+INTRODUCTION
+
+
+As I look back now on the sensational events of the past months since
+the great European War began, it seems to me as if there had never been
+a period in Craig Kennedy’s life more replete with thrilling adventures
+than this.
+
+In fact, scarcely had one mysterious event been straightened out from
+the tangled skein, when another, even more baffling, crowded on its
+very heels.
+
+As was to have been expected with us in America, not all of these
+remarkable experiences grew either directly or indirectly out of the
+war, but there were several that did, and they proved to be only the
+beginning of a succession of events which kept me busy chronicling for
+the _Star_ the exploits of my capable and versatile friend.
+
+Altogether, this period of the war was, I am sure, quite the most
+exciting of the many series of episodes through which Craig has been
+called upon to go. Yet he seemed to meet each situation as it arose
+with a fresh mind, which was amazing even to me who have known him so
+long and so intimately.
+
+As was naturally to be supposed, also, at such a time, it was not long
+before Craig found himself entangled in the marvelous spy system of the
+warring European nations. These systems revealed their devious and dark
+ways, ramifying as they did tentacle-like even across the ocean in
+their efforts to gain their ends in neutral America. Not only so, but,
+as I shall some day endeavor to show later, when the ban of silence
+imposed by neutrality is raised after the war, many of the horrors of
+the war were brought home intimately to us.
+
+I have, after mature consideration, decided that even at present
+nothing but good can come from the publication at least of some part of
+the strange series of adventures through which Kennedy and I have just
+gone, especially those which might, if we had not succeeded, have
+caused most important changes in current history. As for the other
+adventures, no question can be raised about the propriety of their
+publication.
+
+At any rate, it came about that early in August, when the war cloud was
+just beginning to loom blackest, Kennedy was unexpectedly called into
+one of the strangest, most dangerous situations in which his peculiar
+and perilous profession had ever involved him.
+
+
+
+
+CHAPTER I
+THE WAR TERROR
+
+
+“I must see Professor Kennedy—where is he?—I must see him, for God’s
+sake!”
+
+I was almost carried off my feet by the inrush of a wild-eyed girl,
+seemingly half crazed with excitement, as she cried out Craig’s name.
+
+Startled by my own involuntary exclamation of surprise which followed
+the vision that shot past me as I opened our door in response to a
+sudden, sharp series of pushes at the buzzer, Kennedy bounded swiftly
+toward me, and the girl almost flung herself upon him.
+
+“Why, Miss—er—Miss—my dear young lady—what’s the matter?” he stammered,
+catching her by the arm gently.
+
+As Kennedy forced our strange visitor into a chair, I observed that she
+was all a-tremble. Her teeth fairly chattered. Alternately her nervous,
+peaceless hands clutched at an imaginary something in the air, as if
+for support, then, finding none, she would let her wrists fall supine,
+while she gazed about with quivering lips and wild, restless eyes.
+Plainly, there was something she feared. She was almost over the verge
+of hysteria.
+
+She was a striking girl, of medium height and slender form, but it was
+her face that fascinated me, with its delicately molded features,
+intense unfathomable eyes of dark brown, and lips that showed her
+idealistic, high-strung temperament.
+
+“Please,” he soothed, “get yourself together, please—try! What is the
+matter?”
+
+She looked about, as if she feared that the very walls had eyes and
+ears. Yet there seemed to be something bursting from her lips that she
+could not restrain.
+
+“My life,” she cried wildly, “my life is at stake. Oh—help me, help me!
+Unless I commit a murder to-night, I shall be killed myself!”
+
+The words sounded so doubly strange from a girl of her evident
+refinement that I watched her narrowly, not sure yet but that we had a
+plain case of insanity to deal with.
+
+“A murder?” repeated Kennedy incredulously. “_You_ commit a murder?”
+
+Her eyes rested on him, as if fascinated, but she did not flinch as she
+replied desperately, “Yes—Baron Kreiger—you know, the German diplomat
+and financier, who is in America raising money and arousing sympathy
+with his country.”
+
+“Baron Kreiger!” exclaimed Kennedy in surprise, looking at her more
+keenly.
+
+We had not met the Baron, but we had heard much about him, young,
+handsome, of an old family, trusted already in spite of his youth by
+many of the more advanced of old world financial and political leaders,
+one who had made a most favorable impression on democratic America at a
+time when such impressions were valuable.
+
+Glancing from one of us to the other, she seemed suddenly, with a great
+effort, to recollect herself, for she reached into her chatelaine and
+pulled out a card from a case.
+
+It read simply, “Miss Paula Lowe.”
+
+“Yes,” she replied, more calmly now to Kennedy’s repetition of the
+Baron’s name, “you see, I belong to a secret group.” She appeared to
+hesitate, then suddenly added, “I am an anarchist.”
+
+She watched the effect of her confession and, finding the look on
+Kennedy’s face encouraging rather than shocked, went on breathlessly:
+“We are fighting war with war—this iron-bound organization of men and
+women. We have pledged ourselves to exterminate all kings, emperors and
+rulers, ministers of war, generals—but first of all the financiers who
+lend money that makes war possible.”
+
+She paused, her eyes gleaming momentarily with something like the
+militant enthusiasm that must have enlisted her in the paradoxical war
+against war.
+
+“We are at least going to make another war impossible!” she exclaimed,
+for the moment evidently forgetting herself.
+
+“And your plan?” prompted Kennedy, in the most matter-of-fact manner,
+as though he were discussing an ordinary campaign for social
+betterment. “How were you to—reach the Baron?”
+
+“We had a drawing,” she answered with amazing calmness, as if the mere
+telling relieved her pent-up feelings. “Another woman and I were
+chosen. We knew the Baron’s weakness for a pretty face. We planned to
+become acquainted with him—lure him on.”
+
+Her voice trailed off, as if, the first burst of confidence over, she
+felt something that would lock her secret tighter in her breast.
+
+A moment later she resumed, now talking rapidly, disconnectedly, giving
+Kennedy no chance to interrupt or guide the conversation.
+
+“You don’t know, Professor Kennedy,” she began again, “but there are
+similar groups to ours in European countries and the plan is to strike
+terror and consternation everywhere in the world at once. Why, at our
+headquarters there have been drawn up plans and agreements with other
+groups and there are set down the time, place, and manner of all
+the—the removals.”
+
+Momentarily she seemed to be carried away by something like the
+fanaticism of the fervor which had at first captured her, even still
+held her as she recited her incredible story.
+
+“Oh, can’t you understand?” she went on, as if to justify herself. “The
+increase in armies, the frightful implements of slaughter, the total
+failure of the peace propaganda—they have all defied civilization!
+
+“And then, too, the old, red-blooded emotions of battle have all been
+eliminated by the mechanical conditions of modern warfare in which men
+and women are just so many units, automata. Don’t you see? To fight war
+with its own weapons—that has become the only last resort.”
+
+Her eager, flushed face betrayed the enthusiasm which had once carried
+her into the “Group,” as she called it. I wondered what had brought her
+now to us.
+
+“We are no longer making war against man,” she cried. “We are making
+war against picric acid and electric wires!”
+
+I confess that I could not help thinking that there was no doubt that
+to a certain type of mind the reasoning might appeal most strongly.
+
+“And you would do it in war time, too?” asked Kennedy quickly.
+
+She was ready with an answer. “King George of Greece was killed at the
+head of his troops. Remember Nazim Pasha, too. Such people are easily
+reached in time of peace and in time of war, also, by sympathizers on
+their own side. That’s it, you see—we have followers of all
+nationalities.”
+
+She stopped, her burst of enthusiasm spent. A moment later she leaned
+forward, her clean-cut profile showing her more earnest than before.
+“But, oh, Professor Kennedy,” she added, “it is working itself out to
+be more terrible than war itself!”
+
+“Have any of the plans been carried out yet?” asked Craig, I thought a
+little superciliously, for there had certainly been no such wholesale
+assassination yet as she had hinted at.
+
+She seemed to catch her breath. “Yes,” she murmured, then checked
+herself as if in fear of saying too much. “That is, I—I think so.”
+
+I wondered if she were concealing something, perhaps had already had a
+hand in some such enterprise and it had frightened her.
+
+Kennedy leaned forward, observing the girl’s discomfiture. “Miss Lowe,”
+he said, catching her eye and holding it almost hypnotically, “why have
+you come to see me?”
+
+The question, pointblank, seemed to startle her. Evidently she had
+thought to tell only as little as necessary, and in her own way. She
+gave a little nervous laugh, as if to pass it off. But Kennedy’s eyes
+conquered.
+
+“Oh, can’t you understand yet?” she exclaimed, rising passionately and
+throwing out her arms in appeal. “I was carried away with my hatred of
+war. I hate it yet. But now—the sudden realization of what this compact
+all means has—well, caused something in me to—to snap. I don’t care
+what oath I have taken. Oh, Professor Kennedy, you—you must save him!”
+
+I looked up at her quickly. What did she mean? At first she had come to
+be saved herself. “You must save him!” she implored.
+
+Our door buzzer sounded.
+
+She gazed about with a hunted look, as if she felt that some one had
+even now pursued her and found out.
+
+“What shall I do?” she whispered. “Where shall I go?”
+
+“Quick—in here. No one will know,” urged Kennedy, opening the door to
+his room. He paused for an instant, hurriedly. “Tell me—have you and
+this other woman met the Baron yet? How far has it gone?”
+
+The look she gave him was peculiar. I could not fathom what was going
+on in her mind. But there was no hesitation about her answer. “Yes,”
+she replied, “I—we have met him. He is to come back to New York from
+Washington to-day—this afternoon—to arrange a private loan of five
+million dollars with some bankers secretly. We were to see him
+to-night—a quiet dinner, after an automobile ride up the Hudson—”
+
+“Both of you?” interrupted Craig.
+
+“Yes—that—that other woman and myself,” she repeated, with a peculiar
+catch in her voice. “To-night was the time fixed in the drawing for
+the—”
+
+The word stuck in her throat. Kennedy understood. “Yes, yes,” he
+encouraged, “but who is the other woman?”
+
+Before she could reply, the buzzer had sounded again and she had
+retreated from the door. Quickly Kennedy closed it and opened the
+outside door.
+
+It was our old friend Burke of the Secret Service.
+
+Without a word of greeting, a hasty glance seemed to assure him that
+Kennedy and I were alone. He closed the door himself, and, instead of
+sitting down, came close to Craig.
+
+“Kennedy,” he blurted out in a tone of suppressed excitement, “can I
+trust you to keep a big secret?”
+
+Craig looked at him reproachfully, but said nothing.
+
+“I beg your pardon—a thousand times,” hastened Burke. “I was so
+excited, I wasn’t thinking—”
+
+“Once is enough, Burke,” laughed Kennedy, his good nature restored at
+Burke’s crestfallen appearance.
+
+“Well, you see,” went on the Secret Service man, “this thing is so very
+important that—well, I forgot.”
+
+He sat down and hitched his chair close to us, as he went on in a
+lowered, almost awestruck tone.
+
+“Kennedy,” he whispered, “I’m on the trail, I think, of something
+growing out of these terrible conditions in Europe that will tax the
+best in the Secret Service. Think of it, man. There’s an organization,
+right here in this city, a sort of assassin’s club, as it were, aimed
+at all the powerful men the world over. Why, the most refined and
+intellectual reformers have joined with the most red-handed anarchists
+and—”
+
+“Sh! not so loud,” cautioned Craig. “I think I have one of them in the
+next room. Have they done anything yet to the Baron?”
+
+It was Burke’s turn now to look from one to the other of us in
+unfeigned surprise that we should already know something of his secret.
+
+“The Baron?” he repeated, lowering his voice. “What Baron?”
+
+It was evident that Burke knew nothing, at least of this new plot which
+Miss Lowe had indicated. Kennedy beckoned him over to the window
+furthest from the door to his own room.
+
+“What have you discovered?” he asked, forestalling Burke in the
+questioning. “What has happened?”
+
+“You haven’t heard, then?” replied Burke.
+
+Kennedy nodded negatively.
+
+“Fortescue, the American inventor of fortescite, the new explosive,
+died very strangely this morning.”
+
+“Yes,” encouraged Kennedy, as Burke came to a full stop to observe the
+effect of the information.
+
+“Most incomprehensible, too,” he pursued. “No cause, apparently. But it
+might have been overlooked, perhaps, except for one thing. It wasn’t
+known generally, but Fortescue had just perfected a successful
+electro-magnetic gun—powderless, smokeless, flashless, noiseless and of
+tremendous power. To-morrow he was to have signed the contract to sell
+it to England. This morning he is found dead and the final plans of the
+gun are gone!”
+
+Kennedy and Burke were standing mutely looking at each other.
+
+“Who is in the next room?” whispered Burke hoarsely, recollecting
+Kennedy’s caution of silence.
+
+Kennedy did not reply immediately. He was evidently much excited by
+Burke’s news of the wonderful electro-magnetic gun.
+
+“Burke,” he exclaimed suddenly, “let’s join forces. I think we are both
+on the trail of a world-wide conspiracy—a sort of murder syndicate to
+wipe out war!”
+
+Burke’s only reply was a low whistle that involuntarily escaped him as
+he reached over and grasped Craig’s hand, which to him represented the
+sealing of the compact.
+
+As for me, I could not restrain a mental shudder at the power that
+their first murder had evidently placed in the hands of the anarchists,
+if they indeed had the electro-magnetic gun which inventors had been
+seeking for generations. What might they not do with it—perhaps even
+use it themselves and turn the latest invention against society itself!
+
+Hastily Craig gave a whispered account of our strange visit from Miss
+Lowe, while Burke listened, open-mouthed.
+
+He had scarcely finished when he reached for the telephone and asked
+for long distance.
+
+“Is this the German embassy in Washington?” asked Craig a few moments
+later when he got his number. “This is Craig Kennedy, in New York. The
+United States Secret Service will vouch for me—mention to them Mr.
+Burke of their New York office who is here with me now. I understand
+that Baron Kreiger is leaving for New York to meet some bankers this
+afternoon. He must not do so. He is in the gravest danger if he—What?
+He left last night at midnight and is already here?”
+
+Kennedy turned to us blankly.
+
+The door to his room opened suddenly.
+
+There stood Miss Lowe, gazing wild-eyed at us. Evidently her
+supernervous condition had heightened the keenness of her senses. She
+had heard what we were saying. I tried to read her face. It was not
+fear that I saw there. It was rage; it was jealousy.
+
+“The traitress—it is Marie!” she shrieked.
+
+For a moment, obtusely, I did not understand.
+
+“She has made a secret appointment with him,” she cried.
+
+At last I saw the truth. Paula Lowe had fallen in love with the man she
+had sworn to kill!
+
+
+
+
+CHAPTER II
+THE ELECTRO-MAGNETIC GUN
+
+
+“What shall we do?” demanded Burke, instantly taking in the dangerous
+situation that the Baron’s sudden change of plans had opened up.
+
+“Call O’Connor,” I suggested, thinking of the police bureau of missing
+persons, and reaching for the telephone.
+
+“No, no!” almost shouted Craig, seizing my arm. “The police will
+inevitably spoil it all. No, we must play a lone hand in this if we are
+to work it out. How was Fortescue discovered, Burke?”
+
+“Sitting in a chair in his laboratory. He must have been there all
+night. There wasn’t a mark on him, not a sign of violence, yet his face
+was terribly drawn as though he were gasping for breath or his heart
+had suddenly failed him. So far, I believe, the coroner has no clue and
+isn’t advertising the case.”
+
+“Take me there, then,” decided Craig quickly. “Walter, I must trust
+Miss Lowe to you on the journey. We must all go. That must be our
+starting point, if we are to run this thing down.”
+
+I caught his significant look to me and interpreted it to mean that he
+wanted me to watch Miss Lowe especially. I gathered that taking her was
+in the nature of a third degree and as a result he expected to derive
+some information from her. Her face was pale and drawn as we four piled
+into a taxicab for a quick run downtown to the laboratory of Fortescue
+from which Burke had come directly to us with his story.
+
+“What do you know of these anarchists?” asked Kennedy of Burke as we
+sped along. “Why do you suspect them?”
+
+It was evident that he was discussing the case so that Paula could
+overhear, for a purpose.
+
+“Why, we received a tip from abroad—I won’t say where,” replied Burke
+guardedly, taking his cue. “They call themselves the ‘Group,’ I
+believe, which is a common enough term among anarchists. It seems they
+are composed of terrorists of all nations.”
+
+“The leader?” inquired Kennedy, leading him on.
+
+“There is one, I believe, a little florid, stout German. I think he is
+a paranoiac who believes there has fallen on himself a divine mission
+to end all warfare. Quite likely he is one of those who have fled to
+America to avoid military service. Perhaps, why certainly, you must
+know him—Annenberg, an instructor in economics now at the University?”
+
+Craig nodded and raised his eyebrows in mild surprise. We had indeed
+heard of Annenberg and some of his radical theories which had sometimes
+quite alarmed the conservative faculty. I felt that this was getting
+pretty close home to us now.
+
+“How about Mrs. Annenberg?” Craig asked, recalling the clever young
+wife of the middle-aged professor.
+
+At the mere mention of the name, I felt a sort of start in Miss Lowe,
+who was seated next to me in the taxicab. She had quickly recovered
+herself, but not before I saw that Kennedy’s plan of breaking down the
+last barrier of her reserve was working.
+
+“She is one of them, too,” Burke nodded. “I have had my men out
+shadowing them and their friends. They tell me that the Annenbergs hold
+salons—I suppose you would call them that—attended by numbers of men
+and women of high social and intellectual position who dabble in
+radicalism and all sorts of things.”
+
+“Who are the other leaders?” asked Craig. “Have you any idea?”
+
+“Some idea,” returned Burke. “There seems to be a Frenchman, a tall,
+wiry man of forty-five or fifty with a black mustache which once had a
+military twist. There are a couple of Englishmen. Then there are five
+or six Americans who seem to be active. One, I believe, is a young
+woman.”
+
+Kennedy checked him with a covert glance, but did not betray by a
+movement of a muscle to Miss Lowe that either Burke or himself
+suspected her of being the young woman in question.
+
+“There are three Russians,” continued Burke, “all of whom have escaped
+from Siberia. Then there is at least one Austrian, a Spaniard from the
+Ferrer school, and Tomasso and Enrico, two Italians, rather heavily
+built, swarthy, bearded. They look the part. Of course there are
+others. But these in the main, I think, compose what might be called
+‘the inner circle’ of the ‘Group.’”
+
+It was indeed an alarming, terrifying revelation, as we began to
+realize that Miss Lowe had undoubtedly been telling the truth. Not
+alone was there this American group, evidently, but all over Europe the
+lines of the conspiracy had apparently spread. It was not a casual
+gathering of ordinary malcontents. It went deeper than that. It
+included many who in their disgust at war secretly were not unwilling
+to wink at violence to end the curse. I could not but reflect on the
+dangerous ground on which most of them were treading, shaking the basis
+of all civilization in order to cut out one modern excrescence.
+
+The big fact to us, just at present, was that this group had made
+America its headquarters, that plans had been studiously matured and
+even reduced to writing, if Paula were to be believed. Everything had
+been carefully staged for a great simultaneous blow or series of blows
+that would rouse the whole world.
+
+As I watched I could not escape observing that Miss Lowe followed Burke
+furtively now, as though he had some uncanny power.
+
+Fortescue’s laboratory was in an old building on a side street several
+blocks from the main thoroughfares of Manhattan. He had evidently
+chosen it, partly because of its very inaccessibility in order to
+secure the quiet necessary for his work.
+
+“If he had any visitors last night,” commented Kennedy when our cab at
+last pulled up before the place, “they might have come and gone
+unnoticed.”
+
+We entered. Nothing had been disturbed in the laboratory by the coroner
+and Kennedy was able to gain a complete idea of the case rapidly,
+almost as well as if we had been called in immediately.
+
+Fortescue’s body, it seemed, had been discovered sprawled out in a big
+armchair, as Burke had said, by one of his assistants only a few hours
+before when he had come to the laboratory in the morning to open it.
+Evidently he had been there undisturbed all night, keeping a gruesome
+vigil over his looted treasure house.
+
+As we gleaned the meager facts, it became more evident that whoever had
+perpetrated the crime must have had the diabolical cunning to do it in
+some ordinary way that aroused no suspicion on the part of the victim,
+for there was no sign of any violence anywhere.
+
+As we entered the laboratory, I noted an involuntary shudder on the
+part of Paula Lowe, but, as far as I knew, it was no more than might
+have been felt by anyone under the circumstances.
+
+Fortescue’s body had been removed from the chair in which it had been
+found and lay on a couch at the other end of the room, covered merely
+by a sheet. Otherwise, everything, even the armchair, was undisturbed.
+
+Kennedy pulled back a corner of the sheet, disclosing the face,
+contorted and of a peculiar, purplish hue from the congested blood
+vessels. He bent over and I did so, too. There was an unmistakable odor
+of tobacco on him. A moment Kennedy studied the face before us, then
+slowly replaced the sheet.
+
+Miss Lowe had paused just inside the door and seemed resolutely bound
+not to look at anything. Kennedy meanwhile had begun a most minute
+search of the table and floor of the laboratory near the spot where the
+armchair had been sitting.
+
+In my effort to glean what I could from her actions and expressions I
+did not notice that Craig had dropped to his knees and was peering into
+the shadow under the laboratory table. When at last he rose and
+straightened himself up, however, I saw that he was holding in the palm
+of his hand a half-smoked, gold-tipped cigarette, which had evidently
+fallen on the floor beneath the table where it had burned itself out,
+leaving a blackened mark on the wood.
+
+An instant afterward he picked out from the pile of articles found in
+Fortescue’s pockets and lying on another table a silver cigarette case.
+He snapped it open. Fortescue’s cigarettes, of which there were perhaps
+a half dozen in the case, were cork-tipped.
+
+Some one had evidently visited the inventor the night before, had
+apparently offered him a cigarette, for there were any number of the
+cork-tipped stubs lying about. Who was it? I caught Paula looking with
+fascinated gaze at the gold-tipped stub, as Kennedy carefully folded it
+up in a piece of paper and deposited it in his pocket. Did she know
+something about the case, I wondered?
+
+Without a word, Kennedy seemed to take in the scant furniture of the
+laboratory at a glance and a quick step or two brought him before a
+steel filing cabinet. One drawer, which had not been closed as tightly
+as the rest, projected a bit. On its face was a little typewritten card
+bearing the inscription: “E-M GUN.”
+
+He pulled the drawer open and glanced over the data in it.
+
+“Just what is an electro-magnetic gun?” I asked, interpreting the
+initials on the drawer.
+
+“Well,” he explained as he turned over the notes and sketches, “the
+primary principle involved in the construction of such a gun consists
+in impelling the projectile by the magnetic action of a solenoid, the
+sectional coils or helices of which are supplied with current through
+devices actuated by the projectile itself. In other words, the sections
+of helices of the solenoid produce an accelerated motion of the
+projectile by acting successively on it, after a principle involved in
+the construction of electro-magnetic rock drills and dispatch tubes.
+
+“All projectiles used in this gun of Fortescue’s evidently must have
+magnetic properties and projectiles of iron or containing large
+portions of iron are necessary. You see, many coils are wound around
+the barrel of the gun. As the projectile starts it does so under the
+attraction of those coils ahead which the current makes temporary
+magnets. It automatically cuts off the current from those coils that it
+passes, allowing those further on only to attract it, and preventing
+those behind from pulling it back.”
+
+He paused to study the scraps of plans. “Fortescue had evidently also
+worked out a way of changing the poles of the coils as the projectile
+passed, causing them then to repel the projectile, which must have
+added to its velocity. He seems to have overcome the practical
+difficulty that in order to obtain service velocities with service
+projectiles an enormous number of windings and a tremendously long
+barrel are necessary as well as an abnormally heavy current beyond the
+safe carrying capacity of the solenoid which would raise the
+temperature to a point that would destroy the coils.”
+
+He continued turning over the prints and notes in the drawer. When he
+finished, he looked up at us with an expression that indicated that he
+had merely satisfied himself of something he had already suspected.
+
+“You were right, Burke,” he said. “The final plans are gone.”
+
+Burke, who, in the meantime, had been telephoning about the city in a
+vain effort to locate Baron Kreiger, both at such banking offices in
+Wall Street as he might be likely to visit and at some of the hotels
+most frequented by foreigners, merely nodded. He was evidently at a
+loss completely how to proceed.
+
+In fact, there seemed to be innumerable problems—to warn Baron Kreiger,
+to get the list of the assassinations, to guard Miss Lowe against
+falling into the hands of her anarchist friends again, to find the
+murderer of Fortescue, to prevent the use of the electro-magnetic gun,
+and, if possible, to seize the anarchists before they had a chance to
+carry further their plans.
+
+“There is nothing more that we can do here,” remarked Craig briskly,
+betraying no sign of hesitation. “I think the best thing we can do is
+to go to my own laboratory. There at least there is something I must
+investigate sooner or later.”
+
+No one offering either a suggestion or an objection, we four again
+entered our cab. It was quite noticeable now that the visit had shaken
+Paula Lowe, but Kennedy still studiously refrained from questioning
+her, trusting that what she had seen and heard, especially Burke’s
+report as to Baron Kreiger, would have its effect.
+
+Like everyone visiting Craig’s laboratory for the first time, Miss Lowe
+seemed to feel the spell of the innumerable strange and uncanny
+instruments which he had gathered about him in his scientific warfare
+against crime. I could see that she was becoming more and more nervous,
+perhaps fearing even that in some incomprehensible way he might read
+her own thoughts. Yet one thing I did not detect. She showed no
+disposition to turn back on the course on which she had entered by
+coming to us in the first place.
+
+Kennedy was quickly and deftly testing the stub of the little thin,
+gold-tipped cigarette.
+
+“Excessive smoking,” he remarked casually, “causes neuroses of the
+heart and tobacco has a specific affinity for the coronary arteries as
+well as a tremendous effect on the vagus nerve. But I don’t think this
+was any ordinary smoke.”
+
+He had finished his tests and a quiet smile of satisfaction flitted
+momentarily over his face. We had been watching him anxiously,
+wondering what he had found.
+
+As he looked up he remarked to us, with his eyes fixed on Miss Lowe,
+“That was a ladies’ cigarette. Did you notice the size? There has been
+a woman in this case—presumably.”
+
+The girl, suddenly transformed by the rapid-fire succession of
+discoveries, stood before us like a specter.
+
+“The ‘Group,’ as anarchists call it,” pursued Craig, “is the loosest
+sort of organization conceivable, I believe, with no set membership, no
+officers, no laws—just a place of meeting with no fixity, where the
+comrades get together. Could you get us into the inner circle, Miss
+Lowe?”
+
+Her only answer was a little suppressed scream. Kennedy had asked the
+question merely for its effect, for it was only too evident that there
+was no time, even if she could have managed it, for us to play the
+“stool pigeon.”
+
+Kennedy, who had been clearing up the materials he had used in the
+analysis of the cigarette, wheeled about suddenly. “Where is the
+headquarters of the inner circle?” he shot out.
+
+Miss Lowe hesitated. That had evidently been one of the things she had
+determined not to divulge.
+
+“Tell me,” insisted Kennedy. “You must!”
+
+If it had been Burke’s bulldozing she would never have yielded. But as
+she looked into Kennedy’s eyes she read there that he had long since
+fathomed the secret of her wildly beating heart, that if she would
+accomplish the purpose of saving the Baron she must stop at nothing.
+
+“At—Maplehurst,” she answered in a low tone, dropping her eyes from his
+penetrating gaze, “Professor Annenberg’s home—out on Long Island.”
+
+“We must act swiftly if we are to succeed,” considered Kennedy, his
+tone betraying rather sympathy with than triumph over the wretched girl
+who had at last cast everything in the balance to outweigh the terrible
+situation into which she had been drawn. “To send Miss Lowe for that
+fatal list of assassinations is to send her either back into the power
+of this murderous group and let them know that she has told us, or
+perhaps to involve her again in the completion of their plans.”
+
+She sank back into a chair in complete nervous and physical collapse,
+covering her face with her hands at the realization that in her
+new-found passion to save the Baron she had bared her sensitive soul
+for the dissection of three men whom she had never seen before.
+
+“We must have that list,” pursued Kennedy decisively. “We must visit
+Annenberg’s headquarters.”
+
+“And I?” she asked, trembling now with genuine fear at the thought that
+he might ask her to accompany us as he had on our visit to Fortescue’s
+laboratory that morning.
+
+“Miss Lowe,” said Kennedy, bending over her, “you have gone too far now
+ever to turn back. You are not equal to the trip. Would you like to
+remain here? No one will suspect. Here at least you will be safe until
+we return.”
+
+Her answer was a mute expression of thanks and confidence.
+
+
+
+
+CHAPTER III
+THE MURDER SYNDICATE
+
+
+Quickly now Craig completed his arrangements for the visit to the
+headquarters of the real anarchist leader. Burke telephoned for a
+high-powered car, while Miss Lowe told frankly of the habits of
+Annenberg and the chances of finding his place unguarded, which were
+good in the daytime. Kennedy’s only equipment for the excursion
+consisted in a small package which he took from a cabinet at the end of
+the room, and, with a parting reassurance to Paula Lowe, we were soon
+speeding over the bridge to the borough across the river.
+
+We realized that it might prove a desperate undertaking, but the crisis
+was such that it called for any risk.
+
+Our quest took us to a rather dilapidated old house on the outskirts of
+the little Long Island town. The house stood alone, not far from the
+tracks of a trolley that ran at infrequent intervals. Even a hasty
+reconnoitering showed that to stop our motor at even a reasonable
+distance from it was in itself to arouse suspicion.
+
+Although the house seemed deserted, Craig took no chances, but directed
+the car to turn at the next crossroad and then run back along a road
+back of and parallel to that on which Annenberg’s was situated. It was
+perhaps a quarter of a mile away, across an open field, that we stopped
+and ran the car up along the side of the road in some bushes.
+Annenberg’s was plainly visible and it was not at all likely that
+anyone there would suspect trouble from that quarter.
+
+A hasty conference with Burke followed, in which Kennedy unwrapped his
+small package, leaving part of its contents with him, and adding
+careful instructions.
+
+Then Kennedy and I retraced our steps down the road, across by the
+crossroad, and at last back to the mysterious house.
+
+To all appearance there had been no need of such excessive caution. Not
+a sound or motion greeted us as we entered the gate and made our way
+around to the rear of the house. The very isolation of the house was
+now our protection, for we had no inquisitive neighbors to watch us for
+the instant when Kennedy, with the dexterity of a yeggman, inserted his
+knife between the sashes of the kitchen window and turned the catch
+which admitted us.
+
+We made our way on cautious tiptoe through a dining room to a living
+room, and, finding nothing, proceeded upstairs. There was not a soul,
+apparently, in the house, nor in fact anything to indicate that it was
+different from most small suburban homes, until at last we mounted to
+the attic.
+
+It was finished off in one large room across the back of the house and
+two in front. As we opened the door to the larger room, we could only
+gaze about in surprise. This was the rendezvous, the arsenal, literary,
+explosive and toxicological of the “Group.” Ranged on a table were all
+the materials for bomb-making, while in a cabinet I fancied there were
+poisons enough to decimate a city.
+
+On the walls were pictures, mostly newspaper prints, of the assassins
+of McKinley, of King Humbert, of the King of Greece, of King Carlos and
+others, interspersed with portraits of anarchist and anti-militarist
+leaders of all lands.
+
+Kennedy sniffed. Over all I, too, could catch the faint odor of stale
+tobacco. No time was to be lost, however, and while Craig set to work
+rapidly going through the contents of a desk in the corner, I glanced
+over the contents of a drawer of a heavy mission table.
+
+“Here’s some of Annenberg’s literature,” I remarked, coming across a
+small pile of manuscript, entitled “The Human Slaughter House.”
+
+“Read it,” panted Kennedy, seeing that I had about completed my part of
+the job. “It may give a clue.”
+
+Hastily I scanned the mad, frantic indictment of war, while Craig
+continued in his search:
+
+“I see wild beasts all around me, distorted unnaturally, in a life and
+death struggle, with bloodshot eyes, with foaming, gnashing mouths.
+They attack and kill one another and try to mangle each other. I leap
+to my feet. I race out into the night and tread on quaking flesh, step
+on hard heads, and stumble over weapons and helmets. Something is
+clutching at my feet like hands, so that I race away like a hunted deer
+with the hounds at his heels—and ever over more bodies—breathless… out
+of one field into another. Horror is crooning over my head. Horror is
+crooning beneath my feet. And nothing but dying, mangled flesh!
+
+“Of a sudden I see nothing but blood before me. The heavens have opened
+and the red blood pours in through the windows. Blood wells up on an
+altar. The walls run blood from the ceiling to the floor and… a giant
+of blood stands before me. His beard and his hair drip blood. He seats
+himself on the altar and laughs from thick lips. The black executioner
+raises his sword and whirls it above my head. Another moment and my
+head will roll down on the floor. Another moment and the red jet will
+spurt from my neck.
+
+“Murderers! Murderers! None other than murderers!”
+
+I paused in the reading. “There’s nothing here,” I remarked, glancing
+over the curious document for a clue, but finding none.
+
+“Well,” remarked Craig contemplatively, “one can at least easily
+understand how sensitive and imaginative people who have fallen under
+the influence of one who writes in that way can feel justified in
+killing those responsible for bringing such horrors on the human race.
+Hello—what’s this?”
+
+He had discovered a false back of one of the drawers in the desk and
+had jimmied it open. On the top of innumerable papers lay a large linen
+envelope. On its face it bore in typewriting, just like the card on the
+drawer at Fortescue’s, “E-M GUN.”
+
+“It is the original envelope that contained the final plans of the
+electro-magnetic gun,” he explained, opening it.
+
+The envelope was empty. We looked at each other a moment in silence.
+What had been done with the plans?
+
+Suddenly a bell rang, startling me beyond measure. It was, however,
+only the telephone, of which an extension reached up into the
+attic-arsenal. Some one, who did not know that we were there, was
+evidently calling up.
+
+Kennedy quickly unhooked the receiver with a hasty motion to me to be
+silent.
+
+“Hello,” I heard him answer. “Yes, this is it.”
+
+He had disguised his voice. I waited anxiously and watched his face to
+gather what response he received.
+
+“The deuce!” he exclaimed, with his hand over the transmitter so that
+his voice would not be heard at the other end of the line.
+
+“What’s the matter?” I asked eagerly.
+
+“It was Mrs. Annenberg—I am sure. But she was too keen for me. She
+caught on. There must be some password or form of expression that they
+use, which we don’t know, for she hung up the receiver almost as soon
+as she heard me.”
+
+Kennedy waited a minute or so. Then he whistled into the transmitter.
+It was done apparently to see whether there was anyone listening. But
+there was no answer.
+
+“Operator, operator!” he called insistently, moving the hook up and
+down. “Yes, operator. Can you tell me what number that was which just
+called?”
+
+He waited impatiently.
+
+“Bleecker—7l80,” he repeated after the girl. “Thank you. Information,
+please.”
+
+Again we waited, as Craig tried to trace the call up.
+
+“What is the street address of Bleecker, 7180?” he asked. “Five hundred
+and one East Fifth—a tenement. Thank you.”
+
+“A tenement?” I repeated blankly.
+
+“Yes,” he cried, now for the first time excited. “Don’t you begin to
+see the scheme? I’ll wager that Baron Kreiger has been lured to New
+York to purchase the electro-magnetic gun which they have stolen from
+Fortescue and the British. That is the bait that is held out to him by
+the woman. Call up Miss Lowe at the laboratory and see if she knows the
+place.”
+
+I gave central the number, while he fell to at the little secret drawer
+of the desk again. The grinding of the wheels of a passing trolley
+interfered somewhat with giving the number and I had to wait a moment.
+
+“Ah—Walter—here’s the list!” almost shouted Kennedy, as he broke open a
+black-japanned dispatch box in the desk.
+
+I bent over it, as far as the slack of the telephone wire of the
+receiver at my ear would permit. Annenberg had worked with amazing care
+and neatness on the list, even going so far as to draw at the top, in
+black, a death’s head. The rest of it was elaborately prepared in
+flaming red ink.
+
+Craig gasped to observe the list of world-famous men marked for
+destruction in London, Paris, Berlin, Rome, Vienna, St. Petersburg, and
+even in New York and Washington.
+
+“What is the date set?” I asked, still with my ear glued to the
+receiver.
+
+“To-night and to-morrow,” he replied, stuffing the fateful sheet into
+his pocket.
+
+Rummaging about in the drawer of the table, I had come to a package of
+gold-tipped cigarettes which had interested me and I had left them out.
+Kennedy was now looking at them curiously.
+
+“What is to be the method, do you suppose?” I asked.
+
+“By a poison that is among the most powerful, approaching even
+cyanogen,” he replied confidently, tapping the cigarettes. “Do you
+smell the odor in this room? What is it like?”
+
+“Stale tobacco,” I replied.
+
+“Exactly—nicotine. Two or three drops on the mouth-end of a cigar or
+cigarette. The intended victim thinks it is only natural. But it is the
+purest form of the deadly alkaloid—fatal in a few minutes, too.”
+
+He examined the thin little cigarettes more carefully. “Nicotine,” he
+went on, “was about the first alkaloid that was recovered from the body
+by chemical analysis in a homicide case. That is the penetrating,
+persistent odor you smelled at Fortescue’s and also here. It’s a very
+good poison—if you are not particular about being discovered. A pound
+of ordinary smoking tobacco contains from a half to an ounce of it. It
+is almost entirely consumed by combustion; otherwise a pipeful would be
+fatal. Of course they may have thought that investigators would believe
+that their victims were inveterate smokers. But even the worst tobacco
+fiend wouldn’t show traces of the weed to such an extent.”
+
+Miss Lowe answered at last and Kennedy took the telephone.
+
+“What is at five hundred and one East Fifth?” he asked.
+
+“A headquarters of the Group in the city,” she answered. “Why?”
+
+“Well, I believe that the plans of that gun are there and that the
+Baron—”
+
+“You damned spies!” came a voice from behind us.
+
+Kennedy dropped the receiver, turning quickly, his automatic gleaming
+in his hand.
+
+There was just a glimpse of a man with glittering bright blue eyes that
+had an almost fiendish, baleful glare. An instant later the door which
+had so unexpectedly opened banged shut, we heard a key turn in the
+lock—and the man dropped to the floor before even Kennedy’s automatic
+could test its ability to penetrate wood on a chance at hitting
+something the other side of it.
+
+We were prisoners!
+
+My mind worked automatically. At this very moment, perhaps, Baron
+Kreiger might be negotiating for the electro-magnetic gun. We had found
+out where he was, in all probability, but we were powerless to help
+him. I thought of Miss Lowe, and picked up the receiver which Kennedy
+had dropped.
+
+She did not answer. The wire had been cut. We were isolated!
+
+Kennedy had jumped to the window. I followed to restrain him, fearing
+that he had some mad scheme for climbing out. Instead, quickly he
+placed a peculiar arrangement, from the little package he had brought,
+holding it to his eye as if sighting it, his right hand grasping a
+handle as one holds a stereoscope. A moment later, as I examined it
+more closely, I saw that instead of looking at anything he had before
+him a small parabolic mirror turned away from him.
+
+His finger pressed alternately on a button on the handle and I could
+see that there flashed in the little mirror a minute incandescent lamp
+which seemed to have a special filament arrangement.
+
+The glaring sun was streaming in at the window and I wondered what
+could possibly be accomplished by the little light in competition with
+the sun itself.
+
+“Signaling by electric light in the daytime may sound to you
+ridiculous,” explained Craig, still industriously flashing the light,
+“but this arrangement with Professor Donath’s signal mirror makes it
+possible, all right.
+
+“I hadn’t expected this, but I thought I might want to communicate with
+Burke quickly. You see, I sight the lamp and then press the button
+which causes the light in the mirror to flash. It seems a paradox that
+a light like this can be seen from a distance of even five miles and
+yet be invisible to one for whom it was not intended, but it is so. I
+use the ordinary Morse code—two seconds for a dot, six for a dash with
+a four-second interval.”
+
+“What message did you send?” I asked.
+
+“I told him that Baron Kreiger was at five hundred and one East Fifth,
+probably; to get the secret service office in New York by wire and have
+them raid the place, then to come and rescue us. That was Annenberg. He
+must have come up by that trolley we heard passing just before.”
+
+The minutes seemed ages as we waited for Burke to start the machinery
+of the raid and then come for us.
+
+“No—you can’t have a cigarette—and if I had a pair of bracelets with
+me, I’d search you myself,” we heard a welcome voice growl outside the
+door a few minutes later. “Look in that other pocket, Tom.”
+
+The lock grated back and there stood Burke holding in a grip of steel
+the undersized Annenberg, while the chauffeur who had driven our car
+swung open the door.
+
+“I’d have been up sooner,” apologized Burke, giving the anarchist an
+extra twist just to let him know that he was at last in the hands of
+the law, “only I figured that this fellow couldn’t have got far away in
+this God-forsaken Ducktown and I might as well pick him up while I had
+a chance. That’s a great little instrument of yours, Kennedy. I got
+you, fine.”
+
+Annenberg, seeing we were now four to one, concluded that discretion
+was the better part of valor and ceased to struggle, though now and
+then I could see he glanced at Kennedy out of the corner of his eye. To
+every question he maintained a stolid silence.
+
+A few minutes later, with the arch anarchist safely pinioned between
+us, we were speeding back toward New York, laying plans for Burke to
+dispatch warnings abroad to those whose names appeared on the fatal
+list, and at the same time to round up as many of the conspirators as
+possible in America.
+
+As for Kennedy, his main interest now lay in Baron Kreiger and Paula.
+While she had been driven frantic by the outcome of the terrible pact
+into which she had been drawn, some one, undoubtedly, had been trying
+to sell Baron Kreiger the gun that had been stolen from the American
+inventor. Once they had his money and he had received the plans of the
+gun, a fatal cigarette would be smoked. Could we prevent it?
+
+On we tore back to the city, across the bridge and down through the
+canyons of East Side streets.
+
+At last we pulled up before the tenement at five hundred and one. As we
+did so, one of Burke’s men jumped out of the doorway.
+
+“Are we in time?” shouted Burke.
+
+“It’s an awful mix-up,” returned the man. “I can’t make anything out of
+it, so I ordered ’em all held here till you came.”
+
+We pushed past without a word of criticism of his wonderful acumen.
+
+On the top floor we came upon a young man, bending over the form of a
+girl who had fainted. On the floor of the middle of the room was a mass
+of charred papers which had evidently burned a hole in the carpet
+before they had been stamped out. Near by was an unlighted cigarette,
+crushed flat on the floor.
+
+“How is she?” asked Kennedy anxiously of the young man, as he dropped
+down on the other side of the girl.
+
+It was Paula. She had fainted, but was just now coming out of the
+borderland of unconsciousness.
+
+“Was I in time? Had he smoked it?” she moaned weakly, as there swam
+before her eyes, evidently, a hazy vision of our faces.
+
+Kennedy turned to the young man.
+
+“Baron Kreiger, I presume?” he inquired.
+
+The young man nodded.
+
+“Burke of the Secret Service,” introduced Craig, indicating our friend.
+“My name is Kennedy. Tell what happened.”
+
+“I had just concluded a transaction,” returned Kreiger in good but
+carefully guarded English. “Suddenly the door burst open. She seized
+these papers and dashed a cigarette out of my hands. The next instant
+she had touched a match to them and had fallen in a faint almost in the
+blaze. Strangest experience I ever had in my life. Then all these other
+fellows came bursting in—said they were Secret Service men, too.”
+
+Kennedy had no time to reply, for a cry from Annenberg directed our
+attention to the next room where on a couch lay a figure all huddled
+up.
+
+As we looked we saw it was a woman, her head sweating profusely, and
+her hands cold and clammy. There was a strange twitching of the muscles
+of the face, the pupils of her eyes were widely dilated, her pulse weak
+and irregular. Evidently her circulation had failed so that it
+responded only feebly to stimulants, for her respiration was slow and
+labored, with loud inspiratory gasps.
+
+Annenberg had burst with superhuman strength from Burke’s grasp and was
+kneeling by the side of his wife’s deathbed.
+
+“It—was all Paula’s fault—” gasped the woman. “I—knew I had
+better—carry it through—like the Fortescue visit—alone.”
+
+I felt a sense of reassurance at the words. At least my suspicions had
+been unfounded. Paula was innocent of the murder of Fortescue.
+
+“Severe, acute nicotine poisoning,” remarked Kennedy, as he rejoined us
+a moment later. “There is nothing we can do—now.”
+
+Paula moved at the words, as though they had awakened a new energy in
+her. With a supreme effort she raised herself.
+
+“Then I—I failed?” she cried, catching sight of Kennedy.
+
+“No, Miss Lowe,” he answered gently. “You won. The plans of the
+terrible gun are destroyed. The Baron is safe. Mrs. Annenberg has
+herself smoked one of the fatal cigarettes intended for him.”
+
+Kreiger looked at us, uncomprehending. Kennedy picked up the crushed,
+unlighted cigarette and laid it in the palm of his hand beside another,
+half smoked, which he had found beside Mrs. Annenberg.
+
+“They are deadly,” he said simply to Kreiger. “A few drops of pure
+nicotine hidden by that pretty gilt tip would have accomplished all
+that the bitterest anarchist could desire.”
+
+All at once Kreiger seemed to realize what he had escaped so narrowly.
+He turned toward Paula. The revulsion of her feelings at seeing him
+safe was too much for her shattered nerves.
+
+With a faint little cry, she tottered.
+
+Before any of us could reach her, he had caught her in his arms and
+imprinted a warm kiss on the insensible lips.
+
+“Some water—quick!” he cried, still holding her close.
+
+
+
+
+CHAPTER IV
+THE AIR PIRATE
+
+
+Rounding up the “Group” took several days, and it proved to be a great
+story for the _Star_. I was pretty fagged when it was all over, but
+there was a great deal of satisfaction in knowing that we had
+frustrated one of the most daring anarchist plots of recent years.
+
+“Can you arrange to spend the week-end with me at Stuyvesant
+Verplanck’s at Bluffwood?” asked Kennedy over the telephone, the
+afternoon that I had completed my work on the newspaper of undoing what
+Annenberg and the rest had attempted.
+
+“How long since society took you up?” I asked airily, adding, “Is it a
+large house party you are getting up?”
+
+“You have heard of the so-called ‘phantom bandit’ of Bluffwood, haven’t
+you?” he returned rather brusquely, as though there was no time now for
+bantering.
+
+I confess that in the excitement of the anarchists I had forgotten it,
+but now I recalled that for several days I had been reading little
+paragraphs about robberies on the big estates on the Long Island shore
+of the Sound. One of the local correspondents had called the robber a
+“phantom bandit,” but I had thought it nothing more than an attempt to
+make good copy out of a rather ordinary occurrence.
+
+“Well,” he hurried on, “that’s the reason why I have been ‘taken up by
+society,’ as you so elegantly phrase it. From the secret hiding-places
+of the boudoirs and safes of fashionable women at Bluffwood, thousands
+of dollars’ worth of jewels and other trinkets have mysteriously
+vanished. Of course you’ll come along. Why, it will be just the story
+to tone up that alleged page of society news you hand out in the Sunday
+_Star_. There—we’re quits now. Seriously, though, Walter, it really
+seems to be a very baffling case, or rather series of cases. The whole
+colony out there is terrorized. They don’t know who the robber is, or
+how he operates, or who will be the next victim, but his skill and
+success seem almost uncanny. Mr. Verplanck has put one of his cars at
+my disposal and I’m up here at the laboratory gathering some apparatus
+that may be useful. I’ll pick you up anywhere between this and the
+Bridge—how about Columbus Circle in half an hour?”
+
+“Good,” I agreed, deciding quickly from his tone and manner of
+assurance that it would be a case I could not afford to miss.
+
+The Stuyvesant Verplancks, I knew, were among the leaders of the rather
+recherché society at Bluffwood, and the pace at which Bluffwood moved
+and had its being was such as to guarantee a good story in one way or
+another.
+
+“Why,” remarked Kennedy, as we sped out over the picturesque roads of
+the north shore of Long Island, “this fellow, or fellows, seems to have
+taken the measure of all the wealthy members of the exclusive
+organizations out there—the Westport Yacht Club, the Bluffwood Country
+Club, the North Shore Hunt, and all of them. It’s a positive scandal,
+the ease with which he seems to come and go without detection, striking
+now here, now there, often at places that it seems physically
+impossible to get at, and yet always with the same diabolical skill and
+success. One night he will take some baubles worth thousands, the next
+pass them by for something apparently of no value at all, a piece of
+bric-à-brac, a bundle of letters, anything.”
+
+“Seems purposeless, insane, doesn’t it?” I put in.
+
+“Not when he always takes something—often more valuable than money,”
+returned Craig.
+
+He leaned back in the car and surveyed the glimpses of bay and
+countryside as we were whisked by the breaks in the trees.
+
+“Walter,” he remarked meditatively, “have you ever considered the
+possibilities of blackmail if the right sort of evidence were obtained
+under this new ‘white-slavery act’? Scandals that some of the fast set
+may be inclined to wink at, that at worst used to end in Reno, become
+felonies with federal prison sentences looming up in the background.
+Think it over.”
+
+Stuyvesant Verplanck had telephoned rather hurriedly to Craig earlier
+in the day, retaining his services, but telling only in the briefest
+way of the extent of the depredations, and hinting that more than
+jewelry might be at stake.
+
+It was a pleasant ride, but we finished it in silence. Verplanck was,
+as I recalled, a large masterful man, one of those who demanded and
+liked large things—such as the estate of several hundred acres which we
+at last entered.
+
+It was on a neck of land with the restless waters of the Sound on one
+side and the calmer waters of the bay on the other. Westport Bay lay in
+a beautifully wooded, hilly country, and the house itself was on an
+elevation, with a huge sweep of terraced lawn before it down to the
+water’s edge. All around, for miles, were other large estates, a
+veritable colony of wealth.
+
+As we pulled up under the broad stone porte-cochère, Verplanck, who had
+been expecting us, led the way into his library, a great room,
+literally crowded with curios and objects of art which he had collected
+on his travels. It was a superb mental workshop, overlooking the bay,
+with a stretch of several miles of sheltered water.
+
+“You will recall,” began Verplanck, wasting no time over preliminaries,
+but plunging directly into the subject, “that the prominent robberies
+of late have been at seacoast resorts, especially on the shores of Long
+Island Sound, within, say, a hundred miles of New York. There has been
+a great deal of talk about dark and muffled automobiles that have
+conveyed mysterious parties swiftly and silently across country.
+
+“My theory,” he went on self-assertively, “is that the attack has been
+made always along water routes. Under shadow of darkness, it is easy to
+slip into one of the sheltered coves or miniature fiords with which the
+north coast of the Island abounds, land a cut-throat crew primed with
+exact information of the treasure on some of these estates. Once the
+booty is secured, the criminal could put out again into the Sound
+without leaving a clue.”
+
+He seemed to be considering his theory. “Perhaps the robberies last
+summer at Narragansett, Newport, and a dozen other New England places
+were perpetrated by the same cracksman. I believe,” he concluded,
+lowering his voice, “that there plies to-day on the wide waters of the
+Sound a slim, swift motor boat which wears the air of a pleasure craft,
+yet is as black a pirate as ever flew the Jolly Roger. She may at this
+moment be anchored off some exclusive yacht club, flying the
+respectable burgee of the club—who knows?”
+
+He paused as if his deductions settled the case so far. He would have
+resumed in the same vein, if the door had not opened. A lady in a
+cobwebby gown entered the room. She was of middle age, but had retained
+her youth with a skill that her sisters of less leisure always envy.
+Evidently she had not expected to find anyone, yet nothing seemed to
+disconcert her.
+
+“Mrs. Verplanck,” her husband introduced, “Professor Kennedy and his
+associate, Mr. Jameson—those detectives we have heard about. We were
+discussing the robberies.”
+
+“Oh, yes,” she said, smiling, “my husband has been thinking of forming
+himself into a vigilance committee. The local authorities are all at
+sea.”
+
+I thought there was a trace of something veiled in the remark and
+fancied, not only then but later, that there was an air of constraint
+between the couple.
+
+“You have not been robbed yourself?” queried Craig tentatively.
+
+“Indeed we have,” exclaimed Verplanck quickly. “The other night I was
+awakened by the noise of some one down here in this very library. I
+fired a shot, wild, and shouted, but before I could get down here the
+intruder had fled through a window, and half rolling down the terraces.
+Mrs. Verplanck was awakened by the rumpus and both of us heard a
+peculiar whirring noise.”
+
+“Like an automobile muffled down,” she put in.
+
+“No,” he asserted vigorously, “more like a powerful motor boat, one
+with the exhaust under water.”
+
+“Well,” she shrugged, “at any rate, we saw no one.”
+
+“Did the intruder get anything?”
+
+“That’s the lucky part. He had just opened this safe apparently and
+begun to ransack it. This is my private safe. Mrs. Verplanck has
+another built into her own room upstairs where she keeps her jewels.”
+
+“It is not a very modern safe, is it?” ventured Kennedy. “The fellow
+ripped off the outer casing with what they call a ‘can-opener.’”
+
+“No. I keep it against fire rather than burglars. But he overlooked a
+box of valuable heirlooms, some silver with the Verplanck arms. I think
+I must have scared him off just in time. He seized a package in the
+safe, but it was only some business correspondence. I don’t relish
+having lost it, particularly. It related to a gentlemen’s agreement a
+number of us had in the recent cotton corner. I suppose the Government
+would like to have it. But—here’s the point. If it is so easy to get in
+and get away, no one in Bluffwood is safe.”
+
+“Why, he robbed the Montgomery Carter place the other night,” remarked
+Mrs. Verplanck, “and almost got a lot of old Mrs. Carter’s jewels as
+well as stuff belonging to her son, Montgomery, Junior. That was the
+first robbery. Mr. Carter, that is Junior—Monty, everyone calls him—and
+his chauffeur almost captured the fellow, but he managed to escape in
+the woods.”
+
+“In the woods?” repeated Craig.
+
+Mrs. Verplanck nodded. “But they saved the loot he was about to take.”
+
+“Oh, no one is safe any more,” reiterated Verplanck. “Carter seems to
+be the only one who has had a real chance at him, and he was able to
+get away neatly.”
+
+“But he’s not the only one who got off without a loss,” she put in
+significantly. “The last visit—” Then she paused.
+
+“Where was the last attempt?” asked Kennedy.
+
+“At the house of Mrs. Hollingsworth—around the point on this side of
+the bay. You can’t see it from here.”
+
+“I’d like to go there,” remarked Kennedy.
+
+“Very well. Car or boat?”
+
+“Boat, I think.”
+
+“Suppose we go in my little runabout, the _Streamline II_? She’s as
+fast as any ordinary automobile.”
+
+“Very good. Then we can get an idea of the harbor.”
+
+“I’ll telephone first that we are coming,” said Verplanck.
+
+“I think I’ll go, too,” considered Mrs. Verplanck, ringing for a heavy
+wrap.
+
+“Just as you please,” said Verplanck.
+
+The _Streamline_ was a three-stepped boat which. Verplanck had built
+for racing, a beautiful craft, managed much like a racing automobile.
+As she started from the dock, the purring drone of her eight cylinders
+sent her feathering over the waves like a skipping stone. She sank back
+into the water, her bow leaping upward, a cloud of spray in her wake,
+like a waterspout.
+
+Mrs. Hollingsworth was a wealthy divorcée, living rather quietly with
+her two children, of whom the courts had awarded her the care. She was
+a striking woman, one of those for whom the new styles of dress seem
+especially to have been designed. I gathered, however, that she was not
+on very good terms with the little Westport clique in which the
+Verplancks moved, or at least not with Mrs. Verplanck. The two women
+seemed to regard each other rather coldly, I thought, although Mr.
+Verplanck, man-like, seemed to scorn any distinctions and was more than
+cordial. I wondered why Mrs. Verplanck had come.
+
+The Hollingsworth house was a beautiful little place down the bay from
+the Yacht Club, but not as far as Verplanck’s, or the Carter estate,
+which was opposite.
+
+“Yes,” replied Mrs. Hollingsworth when the reason for our visit had
+been explained, “the attempt was a failure. I happened to be awake,
+rather late, or perhaps you would call it early. I thought I heard a
+noise as if some one was trying to break into the drawing-room through
+the window. I switched on all the lights. I have them arranged so for
+just that purpose of scaring off intruders. Then, as I looked out of my
+window on the second floor, I fancied I could see a dark figure slink
+into the shadow of the shrubbery at the side of the house. Then there
+was a whirr. It might have been an automobile, although it sounded
+differently from that—more like a motor boat. At any rate, there was no
+trace of a car that we could discover in the morning. The road had been
+oiled, too, and a car would have left marks. And yet some one was here.
+There were marks on the drawing-room window just where I heard the
+sounds.”
+
+Who could it be? I asked myself as we left. I knew that the great army
+of chauffeurs was infested with thieves, thugs and gunmen. Then, too,
+there were maids, always useful as scouts for these corsairs who prey
+on the rich. Yet so adroitly had everything been done in these cases
+that not a clue seemed to have been left behind by which to trace the
+thief.
+
+We returned to Verplanck’s in the _Streamline_ in record time, dined,
+and then found McNeill, a local detective, waiting to add his quota of
+information. McNeill was of the square-toed, double-chinned,
+bull-necked variety, just the man to take along if there was any
+fighting. He had, however, very little to add to the solution of the
+mystery, apparently believing in the chauffeur-and-maid theory.
+
+It was too late to do anything more that night, and we sat on the
+Verplanck porch, overlooking the beautiful harbor. It was a black, inky
+night, with no moon, one of those nights when the myriad lights on the
+boats were mere points in the darkness. As we looked out over the
+water, considering the case which as yet we had hardly started on,
+Kennedy seemed engrossed in the study in black.
+
+“I thought I saw a moving light for an instant across the bay, above
+the boats, and as though it were in the darkness of the hills on the
+other side. Is there a road over there, above the Carter house?” he
+asked suddenly.
+
+“There is a road part of the way on the crest of the hill,” replied
+Mrs. Verplanck. “You can see a car on it, now and then, through the
+trees, like a moving light.”
+
+“Over there, I mean,” reiterated Kennedy, indicating the light as it
+flashed now faintly, then disappeared, to reappear further along, like
+a gigantic firefly in the night.
+
+“N-no,” said Verplanck. “I don’t think the road runs down as far as
+that. It is further up the bay.”
+
+“What is it then?” asked Kennedy, half to himself. “It seems to be
+traveling rapidly. Now it must be about opposite the Carter house.
+There—it has gone.”
+
+We continued to watch for several minutes, but it did not reappear.
+Could it have been a light on the mast of a boat moving rapidly up the
+bay and perhaps nearer to us than we suspected? Nothing further
+happened, however, and we retired early, expecting to start with fresh
+minds on the case in the morning. Several watchmen whom Verplanck
+employed both on the shore and along the driveways were left guarding
+every possible entrance to the estate.
+
+Yet the next morning as we met in the cheery east breakfast room,
+Verplanck’s gardener came in, hat in hand, with much suppressed
+excitement.
+
+In his hand he held an orange which he had found in the shrubbery
+underneath the windows of the house. In it was stuck a long nail and to
+the nail was fastened a tag.
+
+Kennedy read it quickly.
+
+“If this had been a bomb, you and your detectives would never have
+known what struck you.
+
+
+“AQUAERO.”
+
+
+
+
+CHAPTER V
+THE ULTRA-VIOLET RAY
+
+
+“Good Gad, man!” exclaimed Verplanck, who had read it over Craig’s
+shoulder. “What do you make of _that?_”
+
+Kennedy merely shook his head. Mrs. Verplanck was the calmest of all.
+
+“The light,” I cried. “You remember the light? Could it have been a
+signal to some one on this side of the bay, a signal light in the
+woods?”
+
+“Possibly,” commented Kennedy absently, adding, “Robbery with this
+fellow seems to be an art as carefully strategized as a promoter’s plan
+or a merchant’s trade campaign. I think I’ll run over this morning and
+see if there is any trace of anything on the Carter estate.”
+
+Just then the telephone rang insistently. It was McNeill, much excited,
+though he had not heard of the orange incident. Verplanck answered the
+call.
+
+“Have you heard the news?” asked McNeill. “They report this morning
+that that fellow must have turned up last night at Belle Aire.”
+
+“Belle Aire? Why, man, that’s fifty miles away and on the other side of
+the island. He was here last night,” and Verplanck related briefly the
+find of the morning. “No boat could get around the island in that time
+and as for a car—those roads are almost impossible at night.”
+
+“Can’t help it,” returned McNeill doggedly. “The Halstead estate out at
+Belle Aire was robbed last night. It’s spooky all right.”
+
+“Tell McNeill I want to see him—will meet him in the village directly,”
+cut in Craig before Verplanck had finished.
+
+We bolted a hasty breakfast and in one of Verplanck’s cars hurried to
+meet McNeill.
+
+“What do you intend doing?” he asked helplessly, as Kennedy finished
+his recital of the queer doings of the night before.
+
+“I’m going out now to look around the Carter place. Can you come
+along?”
+
+“Surely,” agreed McNeill, climbing into the car. “You know him?”
+
+“No.”
+
+“Then I’ll introduce you. Queer chap, Carter. He’s a lawyer, although I
+don’t think he has much practice, except managing his mother’s estate.”
+
+McNeill settled back in the luxurious car with an exclamation of
+satisfaction.
+
+“What do you think of Verplanck?” he asked.
+
+“He seems to me to be a very public-spirited man,” answered Kennedy
+discreetly.
+
+That, however, was not what McNeill meant and he ignored it. And so for
+the next ten minutes we were entertained with a little retail scandal
+of Westport and Bluffwood, including a tale that seemed to have gained
+currency that Verplanck and Mrs. Hollingsworth were too friendly to
+please Mrs. Verplanck. I set the whole thing down to the hostility and
+jealousy of the towns people who misinterpret everything possible in
+the smart set, although I could not help recalling how quickly she had
+spoken when we had visited the Hollingsworth house in the _Streamline_
+the day before.
+
+Montgomery Carter happened to be at home and, at least openly,
+interposed no objection to our going about the grounds.
+
+“You see,” explained Kennedy, watching the effect of his words as if to
+note whether Carter himself had noticed anything unusual the night
+before, “we saw a light moving over here last night. To tell the truth,
+I half expected you would have a story to add to ours, of a second
+visit.”
+
+Carter smiled. “No objection at all. I’m simply nonplussed at the nerve
+of this fellow, coming back again. I guess you’ve heard what a narrow
+squeak he had with me. You’re welcome to go anywhere, just so long as
+you don’t disturb my study down there in the boathouse. I use that
+because it overlooks the bay—just the place to study over knotty legal
+problems.”
+
+Back of, or in front of the Carter house, according as you fancied it
+faced the bay or not, was the boathouse, built by Carter’s father, who
+had been a great yachtsman in his day and commodore of the club. His
+son had not gone in much for water sports and had converted the corner
+underneath a sort of observation tower into a sort of country law
+office.
+
+“There has always seemed to me to be something strange about that
+boathouse since the old man died,” remarked McNeill in a half whisper
+as we left Carter. “He always keeps it locked and never lets anyone go
+in there, although they say he has it fitted beautifully with hundreds
+of volumes of law books, too.”
+
+Kennedy had been climbing the hill back of the house and now paused to
+look about. Below was the Carter garage.
+
+“By the way,” exclaimed McNeill, as if he had at last hit on a great
+discovery, “Carter has a new chauffeur, a fellow named Wickham. I just
+saw him driving down to the village. He’s a chap that it might pay us
+to watch—a newcomer, smart as a steel trap, they say, but not much of a
+talker.”
+
+“Suppose you take that job—watch him,” encouraged Kennedy. “We can’t
+know too much about strangers here, McNeill.”
+
+“That’s right,” agreed the detective. “I’ll follow him back to the
+village and get a line on him.”
+
+“Don’t be easily discouraged,” added Kennedy, as McNeill started down
+the hill to the garage. “If he is a fox he’ll try to throw you off the
+trail. Hang on.”
+
+“What was that for?” I asked as the detective disappeared. “Did you
+want to get rid of him?”
+
+“Partly,” replied Craig, descending slowly, after a long survey of the
+surrounding country.
+
+We had reached the garage, deserted now except for our own car.
+
+“I’d like to investigate that tower,” remarked Kennedy with a keen look
+at me, “if it could be done without seeming to violate Mr. Carter’s
+hospitality.”
+
+“Well,” I observed, my eye catching a ladder beside the garage,
+“there’s a ladder. We can do no more than try.”
+
+He walked over to the automobile, took a little package out, slipped it
+into his pocket, and a few minutes later we had set the ladder up
+against the side of the boathouse farthest away from the house. It was
+the work of only a moment for Kennedy to scale it and prowl across the
+roof to the tower, while I stood guard at the foot.
+
+“No one has been up there recently,” he panted breathlessly as he
+rejoined me. “There isn’t a sign.”
+
+We took the ladder quietly back to the garage, then Kennedy led the way
+down the shore to a sort of little summerhouse cut off from the
+boathouse and garage by the trees, though over the top of a hedge one
+could still see the boathouse tower.
+
+We sat down, and Craig filled his lungs with the good salt air,
+sweeping his eye about the blue and green panorama as though this were
+a holiday and not a mystery case.
+
+“Walter,” he said at length, “I wish you’d take the car and go around
+to Verplanck’s. I don’t think you can see the tower through the trees,
+but I should like to be sure.”
+
+I found that it could not be seen, though I tried all over the place
+and got myself disliked by the gardener and suspected by a watchman
+with a dog.
+
+It could not have been from the tower of the boathouse that we had seen
+the light, and I hurried back to Craig to tell him so. But when I
+returned, I found that he was impatiently pacing the little rustic
+summerhouse, no longer interested in what he had sent me to find out.
+
+“What has happened?” I asked eagerly.
+
+“Just come out here and I’ll show you something,” he replied, leaving
+the summerhouse and approaching the boathouse from the other side of
+the hedge, on the beach, so that the house itself cut us off from
+observation from Carter’s.
+
+“I fixed a lens on the top of that tower when I was up there,” he
+explained, pointing up at it. “It must be about fifty feet high. From
+there, you see, it throws a reflection down to this mirror. I did it
+because through a skylight in the tower I could read whatever was
+written by anyone sitting at Carter’s desk in the corner under it.”
+
+“Read?” I repeated, mystified.
+
+“Yes, by invisible light,” he continued. “This invisible light
+business, you know, is pretty well understood by this time. I was only
+repeating what was suggested once by Professor Wood of Johns Hopkins.
+Practically all sources of light, you understand, give out more or less
+ultraviolet light, which plays no part in vision whatever. The human
+eye is sensitive to but few of the light rays that reach it, and if our
+eyes were constituted just the least bit differently we should have an
+entirely different set of images.
+
+“But by the use of various devices we can, as it were, translate these
+ultraviolet rays into terms of what the human eye can see. In order to
+do it, all the visible light rays which show us the thing as we see
+it—the tree green, the sky blue—must be cut off. So in taking an
+ultraviolet photograph a screen must be used which will be opaque to
+these visible rays and yet will let the ultraviolet rays through to
+form the image. That gave Professor Wood a lot of trouble. Glass won’t
+do, for glass cuts off the ultraviolet rays entirely. Quartz is a very
+good medium, but it does not cut off all the visible light. In fact
+there is only one thing that will do the work, and that is metallic
+silver.”
+
+I could not fathom what he was driving at, but the fascination of
+Kennedy himself was quite sufficient.
+
+“Silver,” he went on, “is all right if the objects can be illuminated
+by an electric spark or some other source rich in the rays. But it
+isn’t entirely satisfactory when sunlight is concerned, for various
+reasons that I need not bore you with. Professor Wood has worked out a
+process of depositing nickel on glass. That’s it up there,” he
+concluded, wheeling a lower reflector about until it caught the image
+of the afternoon sun thrown from the lens on the top of the tower.
+
+“You see,” he resumed, “that upper lens is concave so that it enlarges
+tremendously. I can do some wonderful tricks with that.”
+
+I had been lighting a cigarette and held a box of safety wind matches
+in my hand.
+
+“Give me that matchbox,” he asked.
+
+He placed it at the foot of the tower. Then he went off, I should say,
+without exaggeration, a hundred feet.
+
+The lettering on the matchbox could be seen in the silvered mirror,
+enlarged to such a point that the letters were plainly visible!
+
+“Think of the possibilities in that,” he added excitedly. “I saw them
+at once. You can read what some one is writing at a desk a hundred,
+perhaps two hundred feet away.”
+
+“Yes,” I cried, more interested in the practical aspects of it than in
+the mechanics and optics. “What have you found?”
+
+“Some one came into the boathouse while you were away,” he said. “He
+had a note. It read, ‘Those new detectives are watching everything. We
+must have the evidence. You must get those letters to-night, without
+fail.’”
+
+“Letters—evidence,” I repeated. “Who wrote it? Who received it?”
+
+“I couldn’t see over the hedge who had entered the boathouse, and by
+the time I got around here he was gone.”
+
+“Was it Wickham—or intended for Wickham?” I asked.
+
+Kennedy shrugged his shoulders.
+
+“We’ll gain nothing by staying here,” he said. “There is just one
+possibility in the case, and I can guard against that only by returning
+to Verplanck’s and getting some of that stuff I brought up here with
+me. Let us go.”
+
+Late in the afternoon though it was, after our return, Kennedy insisted
+on hurrying from Verplanck’s to the Yacht Club up the bay. It was a
+large building, extending out into the water on made land, from which
+ran a long, substantial dock. He had stopped long enough only to ask
+Verplanck to lend him the services of his best mechanician, a Frenchman
+named Armand.
+
+On the end of the yacht club dock Kennedy and Armand set up a large
+affair which looked like a mortar. I watched curiously, dividing my
+attention between them and the splendid view of the harbor which the
+end of the dock commanded on all sides.
+
+“What is this?” I asked finally. “Fireworks?”
+
+“A rocket mortar of light weight,” explained Kennedy, then dropped into
+French as he explained to Armand the manipulation of the thing.
+
+There was a searchlight near by on the dock.
+
+“You can use that?” queried Kennedy.
+
+“Oh, yes. Mr. Verplanck, he is vice-commodore of the club. Oh, yes, I
+can use that. Why, Monsieur?”
+
+Kennedy had uncovered a round brass case. It did not seem to amount to
+much, as compared to some of the complicated apparatus he had used. In
+it was a four-sided prism of glass—I should have said, cut off the
+corner of a huge glass cube.
+
+He handed it to us.
+
+“Look in it,” he said.
+
+It certainly was about the most curious piece of crystal gazing I had
+ever done. Turn the thing any way I pleased and I could see my face in
+it, just as in an ordinary mirror.
+
+“What do you call it?” Armand asked, much interested.
+
+“A triple mirror,” replied Kennedy, and again, half in English and half
+in French, neither of which I could follow, he explained the use of the
+mirror to the mechanician.
+
+We were returning up the dock, leaving Armand with instructions to be
+at the club at dusk, when we met McNeill, tired and disgusted.
+
+“What luck?” asked Kennedy.
+
+“Nothing,” he returned. “I had a ‘short’ shadow and a ‘long’ shadow at
+Wickham’s heels all day. You know what I mean. Instead of one man,
+two—the second sleuthing in the other’s tracks. If he escaped Number
+One, Number Two would take it up, and I was ready to move up into
+Number Two’s place. They kept him in sight about all the time. Not a
+fact. But then, of course, we don’t know what he was doing before we
+took up tailing him. Say,” he added, “I have just got word from an
+agency with which I correspond in New York that it is reported that a
+yeggman named ‘Australia Mac,’ a very daring and clever chap, has been
+attempting to dispose of some of the goods which we know have been
+stolen through one of the worst ‘fences’ in New York.”
+
+“Is that all?” asked Craig, with the mention of Australia Mac showing
+the first real interest yet in anything that McNeill had done since we
+met him the night before.
+
+“All so far. I wired for more details immediately.”
+
+“Do you know anything about this Australia Mac?”
+
+“Not much. No one does. He’s a new man, it seems, to the police here.”
+
+“Be here at eight o’clock, McNeill,” said Craig, as we left the club
+for Verplanck’s. “If you can find out more about this yeggman, so much
+the better.”
+
+“Have you made any progress?” asked Verplanck as we entered the estate
+a few minutes later.
+
+“Yes,” returned Craig, telling only enough to whet his interest.
+“There’s a clue, as I half expected, from New York, too. But we are so
+far away that we’ll have to stick to my original plan. You can trust
+Armand?”
+
+“Absolutely.”
+
+“Then we shall transfer our activity to the Yacht Club to-night,” was
+all that Kennedy vouchsafed.
+
+
+
+
+CHAPTER VI
+THE TRIPLE MIRROR
+
+
+It was the regular Saturday night dance at the club, a brilliant
+spectacle, faces that radiated pleasure, gowns that for startling
+combinations of color would have shamed a Futurist, music that set the
+feet tapping irresistibly—a scene which I shall pass over because it
+really has no part in the story.
+
+The fascination of the ballroom was utterly lost on Craig. “Think of
+all the houses only half guarded about here to-night,” he mused, as we
+joined Armand and McNeill on the end of the dock. I could not help
+noting that that was the only idea which the gay, variegated, sparkling
+tango throng conveyed to him.
+
+In front of the club was strung out a long line of cars, and at the
+dock several speed boats of national and international reputation,
+among them the famous _Streamline II_, at our instant beck and call. In
+it Craig had already placed some rather bulky pieces of apparatus, as
+well as a brass case containing a second triple mirror like that which
+he had left with Armand.
+
+With McNeill, I walked back along the pier, leaving Kennedy with
+Armand, until we came to the wide porch, where we joined the
+wallflowers and the rocking-chair fleet. Mrs. Verplanck, I observed,
+was a beautiful dancer. I picked her out in the throng immediately,
+dancing with Carter.
+
+McNeill tugged at my sleeve. Without a word I saw what he meant me to
+see. Verplanck and Mrs. Hollingsworth were dancing together. Just then,
+across the porch I caught sight of Kennedy at one of the wide windows.
+He was trying to attract Verplanck’s attention, and as he did so I
+worked my way through the throng of chatting couples leaving the floor
+until I reached him. Verplanck, oblivious, finished the dance; then,
+seeming to recollect that he had something to attend to, caught sight
+of us, and ran off during the intermission from the gay crowd to which
+he resigned Mrs. Hollingsworth.
+
+“What is it?” he asked.
+
+“There’s that light down the bay,” whispered Kennedy.
+
+Instantly Verplanck forgot about the dance.
+
+“Where?” he asked.
+
+“In the same place.”
+
+I had not noticed, but Mrs. Verplanck, woman-like, had been able to
+watch several things at once. She had seen us and had joined us.
+
+“Would you like to run down there in the _Streamline?_” he asked. “It
+will only take a few minutes.”
+
+“Very much.”
+
+“What is it—that light again?” she asked, as she joined us in walking
+down the dock.
+
+“Yes,” answered her husband, pausing to look for a moment at the stuff
+Kennedy had left with Armand. Mrs. Verplanck leaned over the
+_Streamline_, turned as she saw me, and said: “I wish I could go with
+you. But evening dress is not the thing for a shivery night in a speed
+boat. I think I know as much about it as Mr. Verplanck. Are you going
+to leave Armand?”
+
+“Yes,” replied Kennedy, taking his place beside Verplanck, who was
+seated at the steering wheel. “Walter and McNeill, if you two will sit
+back there, we’re ready. All right.”
+
+Armand had cast us off and Mrs. Verplanck waved from the end of the
+float as the _Streamline_ quickly shot out into the night, a buzzing,
+throbbing shape of mahogany and brass, with her exhausts sticking out
+like funnels and booming like a pipe organ. It took her only seconds to
+eat into the miles.
+
+“A little more to port,” said Kennedy, as Verplanck swung her around.
+
+Just then the steady droning of the engine seemed a bit less
+rhythmical. Verplanck throttled her down, but it had no effect. He shut
+her off. Something was wrong. As he crawled out into the space forward
+of us where the engine was, it seemed as if the _Streamline_ had broken
+down suddenly and completely.
+
+Here we were floundering around in the middle of the bay.
+
+“Chuck-chuck-chuck,” came in quick staccato out of the night. It was
+Montgomery Carter, alone, on his way across the bay from the club, in
+his own boat.
+
+“Hello—Carter,” called Verplanck.
+
+“Hello, Verplanck. What’s the matter?”
+
+“Don’t know. Engine trouble of some kind. Can you give us a line?”
+
+“I’ve got to go down to the house,” he said, ranging up near us. “Then
+I can take you back. Perhaps I’d better get you out of the way of any
+other boats first. You don’t mind going over and then back?”
+
+Verplanck looked at Craig. “On the contrary,” muttered Craig, as he
+made fast the welcome line.
+
+The Carter dock was some three miles from the club on the other side of
+the bay. As we came up to it, Carter shut off his engine, bent over it
+a moment, made fast, and left us with a hurried, “Wait here.”
+
+Suddenly, overhead, we heard a peculiar whirring noise that seemed to
+vibrate through the air. Something huge, black, monster-like, slid down
+a board runway into the water, traveled a few feet, in white suds and
+spray, rose in the darkness—and was gone!
+
+As the thing disappeared, I thought I could hear a mocking laugh flung
+back at us.
+
+“What is it?” I asked, straining my eyes at what had seemed for an
+instant like a great flying fish with finny tail and huge fins at the
+sides and above.
+
+“‘Aquaero,’” quoted Kennedy quickly. “Don’t you understand—a
+hydroaeroplane—a flying boat. There are hundreds of privately owned
+flying boats now wherever there is navigable water. That was the secret
+of Carter’s boathouse, of the light we saw in the air.”
+
+“But this Aquaero—who is he?” persisted McNeill.
+“Carter—Wickham—Australia Mac?”
+
+We looked at each other blankly. No one said a word. We were captured,
+just as effectively as if we were ironed in a dungeon. There were the
+black water, the distant lights, which at any other time I should have
+said would have been beautiful.
+
+Kennedy had sprung into Carter’s boat.
+
+“The deuce,” he exclaimed. “He’s put her out of business.”
+
+Verplanck, chagrined, had been going over his own engine feverishly.
+“Do you see that?” he asked suddenly, holding up in the light of a
+lantern a little nut which he had picked out of the complicated
+machinery. “It never belonged to this engine. Some one placed it there,
+knowing it would work its way into a vital part with the vibration.”
+
+Who was the person, the only one who could have done it? The answer was
+on my lips, but I repressed it. Mrs. Verplanck herself had been bending
+over the engine when last I saw her. All at once it flashed over me
+that she knew more about the phantom bandit than she had admitted. Yet
+what possible object could she have had in putting the _Streamline_ out
+of commission?
+
+My mind was working rapidly, piecing together the fragmentary facts.
+The remark of Kennedy, long before, instantly assumed new significance.
+What were the possibilities of blackmail in the right sort of evidence?
+The yeggman had been after what was more valuable than jewels—letters!
+Whose? Suddenly I saw the situation. Carter had not been robbed at all.
+He was in league with the robber. That much was a blind to divert
+suspicion. He was a lawyer—some one’s lawyer. I recalled the message
+about letters and evidence, and as I did so there came to mind a
+picture of Carter and the woman he had been dancing with. In return for
+his inside information about the jewels of the wealthy homes of
+Bluffwood, the yeggman was to get something of interest and importance
+to his client.
+
+The situation called for instant action. Yet what could we do, marooned
+on the other side of the bay?
+
+From the Club dock a long finger of light swept out into the night,
+plainly enough near the dock, but diffused and disclosing nothing in
+the distance. Armand had trained it down the bay in the direction we
+had taken, but by the time the beam reached us it was so weak that it
+was lost.
+
+Craig had leaped up on the Carter dock and was capping and uncapping
+with the brass cover the package which contained the triple mirror.
+
+Still in the distance I could see the wide path of light, aimed toward
+us, but of no avail.
+
+“What are you doing?” I asked.
+
+“Using the triple mirror to signal to Armand. It is something better
+than wireless. Wireless requires heavy and complicated apparatus. This
+is portable, heatless, almost weightless, a source of light depending
+for its power on another source of light at a great distance.”
+
+I wondered how Armand could ever detect its feeble ray.
+
+“Even in the case of a rolling ship,” Kennedy continued, alternately
+covering and uncovering the mirror, “the beam of light which this
+mirror reflects always goes back, unerring, to its source. It would do
+so from an aeroplane, so high in the air that it could not be located.
+The returning beam is invisible to anyone not immediately in the path
+of the ray, and the ray always goes to the observer. It is simply a
+matter of pure mathematics practically applied. The angle of incidence
+equals the angle of reflection. There is not a variation of a foot in
+two miles.”
+
+“What message are you sending him?” asked Verplanck.
+
+“To tell Mrs. Hollingsworth to hurry home immediately,” Kennedy
+replied, still flashing the letters according to his code.
+
+“Mrs. Hollingsworth?” repeated Verplanck, looking up.
+
+“Yes. This hydroaeroplane yeggman is after something besides jewels
+to-night. Were those letters that were stolen from you the only ones
+you had in the safe?”
+
+Verplanck looked up quickly. “Yes, yes. Of course.”
+
+“You had none from a woman—”
+
+“No,” he almost shouted. Of a sudden it seemed to dawn on him what
+Kennedy was driving at—the robbery of his own house with no loss except
+of a packet of letters on business, followed by the attempt on Mrs.
+Hollingsworth. “Do you think I’d keep dynamite, even in the safe?”
+
+To hide his confusion he had turned and was bending again over the
+engine.
+
+“How is it?” asked Kennedy, his signaling over.
+
+“Able to run on four cylinders and one propeller,” replied Verplanck.
+
+“Then let’s try her. Watch the engine. I’ll take the wheel.”
+
+Limping along, the engine skipping and missing, the once peerless
+_Streamline_ started back across the bay. Instead of heading toward the
+club, Kennedy pointed her bow somewhere between that and Verplanck’s.
+
+“I wish Armand would get busy,” he remarked, after glancing now and
+then in the direction of the club. “What can be the matter?”
+
+“What do you mean?” I asked.
+
+There came the boom as if of a gun far away in the direction in which
+he was looking, then another.
+
+“Oh, there it is. Good fellow. I suppose he had to deliver my message
+to Mrs. Hollingsworth himself first.”
+
+From every quarter showed huge balls of fire, rising from the sea, as
+it were, with a brilliantly luminous flame.
+
+“What is it?” I asked, somewhat startled.
+
+“A German invention for use at night against torpedo and aeroplane
+attacks. From that mortar Armand has shot half a dozen bombs of
+phosphide of calcium which are hurled far into the darkness. They are
+so constructed that they float after a short plunge and are ignited on
+contact by the action of the salt water itself.”
+
+It was a beautiful pyrotechnic display, lighting up the shore and hills
+of the bay as if by an unearthly flare.
+
+“There’s that thing now!” exclaimed Kennedy.
+
+In the glow we could see a peculiar, birdlike figure flying through the
+air over toward the Hollingsworth house. It was the hydroaeroplane.
+
+Out from the little stretch of lawn under the accentuated shadow of the
+trees, she streaked into the air, swaying from side to side as the
+pilot operated the stabilizers on the ends of the planes to counteract
+the puffs of wind off the land.
+
+How could she ever be stopped?
+
+The _Streamline_, halting and limping, though she was, had almost
+crossed the bay before the light bombs had been fired by Armand. Every
+moment brought the flying boat nearer.
+
+She swerved. Evidently the pilot had seen us at last and realized who
+we were. I was so engrossed watching the thing that I had not noticed
+that Kennedy had given the wheel to Verplanck and was standing in the
+bow, endeavoring to sight what looked like a huge gun.
+
+In rapid succession half a dozen shots rang out. I fancied I could
+almost hear the ripping and tearing of the tough rubber-coated silken
+wings of the hydroaeroplane as the wind widened the perforation the gun
+had made.
+
+She had not been flying high, but now she swooped down almost like a
+gull, seeking to rest on the water. We were headed toward her now, and
+as the flying boat sank I saw one of the passengers rise in his seat,
+swing his arm, and far out something splashed in the bay.
+
+On the water, with wings helpless, the flying boat was no match for the
+_Streamline_ now. She struck at an acute angle, rebounded in the air
+for a moment, and with a hiss skittered along over the waves, planing
+with the help of her exhaust under the step of the boat.
+
+There she was, a hull, narrow, scow-bowed, like a hydroplane, with a
+long pointed stern and a cockpit for two men, near the bow. There were
+two wide, winglike planes, on a light latticework of wood covered with
+silk, trussed and wired like a kite frame, the upper plane about five
+feet above the lower, which was level with the boat deck. We could see
+the eight-cylindered engine which drove a two-bladed wooden propeller,
+and over the stern were the air rudder and the horizontal planes. There
+she was, the hobbled steed now of the phantom bandit who had
+accomplished the seemingly impossible.
+
+In spite of everything, however, the flying boat reached the shore a
+trifle ahead of us. As she did so both figures in her jumped, and one
+disappeared quickly up the bank, leaving the other alone.
+
+“Verplanck, McNeill—get him,” cried Kennedy, as our own boat grated on
+the beach. “Come, Walter, we’ll take the other one.”
+
+The man had seen that there was no safety in flight. Down the shore he
+stood, without a hat, his hair blown pompadour by the wind.
+
+As we approached Carter turned superciliously, unbuttoning his bulky
+khaki life preserver jacket.
+
+“Well?” he asked coolly.
+
+Not for a moment did Kennedy allow the assumed coolness to take him
+back, knowing that Carter’s delay did not cover the retreat of the
+other man.
+
+“So,” Craig exclaimed, “you are the—the air pirate?”
+
+Carter disdained to reply.
+
+“It was you who suggested the millionaire households, full of jewels,
+silver and gold, only half guarded; you, who knew the habits of the
+people; you, who traded that information in return for another piece of
+thievery by your partner, Australia Mac—Wickham he called himself here
+in Bluffwood. It was you—-”
+
+A car drove up hastily, and I noted that we were still on the
+Hollingsworth estate. Mrs. Hollingsworth had seen us and had driven
+over toward us.
+
+“Montgomery!” she cried, startled.
+
+“Yes,” said Kennedy quickly, “air pirate and lawyer for Mrs. Verplanck
+in the suit which she contemplated bringing—”
+
+Mrs. Hollingsworth grew pale under the ghastly, flickering light from
+the bay.
+
+“Oh!” she cried, realizing at what Kennedy hinted, “the letters!”
+
+“At the bottom of the harbor, now,” said Kennedy. “Mr. Verplanck tells
+me he has destroyed his. The past is blotted out as far as that is
+concerned. The future is—for you three to determine. For the present
+I’ve caught a yeggman and a blackmailer.”
+
+
+
+
+CHAPTER VII
+THE WIRELESS WIRETAPPERS
+
+
+Kennedy did not wait at Bluffwood longer than was necessary. It was
+easy enough now to silence Montgomery Carter, and the reconciliation of
+the Verplancks was assured. In the _Star_ I made the case appear at the
+time to involve merely the capture of Australia Mac.
+
+When I dropped into the office the next day as usual, I found that I
+had another assignment that would take me out on Long Island. The story
+looked promising and I was rather pleased to get it.
+
+“Bound for Seaville, I’ll wager,” sounded a familiar voice in my ear,
+as I hurried up to the train entrance at the Long Island corner of the
+Pennsylvania Station.
+
+I turned quickly, to find Kennedy just behind me, breathless and
+perspiring.
+
+“Er—yes,” I stammered in surprise at seeing him so unexpectedly, “but
+where did you come from? How did you know?”
+
+“Let me introduce Mr. Jack Waldon,” he went on, as we edged our way
+toward the gate, “the brother of Mrs. Tracy Edwards, who disappeared so
+strangely from the houseboat _Lucie_ last night at Seaville. That is
+the case you’re going to write up, isn’t it?”
+
+It was then for the first time that I noticed the excited young man
+beside Kennedy was really his companion.
+
+I shook hands with Waldon, who gave me a grip that was both a greeting
+and an added impulse in our general direction through the wicket.
+
+“Might have known the _Star_ would assign you to this Edwards case,”
+panted Kennedy, mopping his forehead, for the heat in the terminal was
+oppressive and the crowd, though not large, was closely packed. “Mr.
+Jameson is my right-hand man,” he explained to Waldon, taking us each
+by the arm and urging us forward. “Waldon was afraid we might miss the
+train or I should have tried to get you, Walter, at the office.”
+
+It was all done so suddenly that they quite took away what remaining
+breath I had, as we settled ourselves to swelter in the smoker instead
+of in the concourse. I did not even protest at the matter-of-fact
+assurance with which Craig assumed that his deduction as to my
+destination was correct.
+
+Waldon, a handsome young fellow in a flannel suit and yachting cap
+somewhat the worse for his evidently perturbed state of mind, seemed to
+eye me for the moment doubtfully, in spite of Kennedy’s cordial
+greeting.
+
+“I’ve had all the first editions of the evening papers,” I hinted as we
+sped through the tunnel, “but the stories seemed to be quite the
+same—pretty meager in details.”
+
+“Yes,” returned Waldon with a glance at Kennedy, “I tried to keep as
+much out of the papers as I could just now for Lucie’s sake.”
+
+“You needn’t fear Jameson,” remarked Kennedy.
+
+He fumbled in his pocket, then paused a moment and shot a glance of
+inquiry at Waldon, who nodded a mute acquiescence to him.
+
+“There seem to have been a number of very peculiar disappearances
+lately,” resumed Kennedy, “but this case of Mrs. Edwards is by far the
+most extraordinary. Of course the _Star_ hasn’t had that—yet,” he
+concluded, handing me a sheet of notepaper.
+
+“Mr. Waldon didn’t give it out, hoping to avoid scandal.”
+
+I took the paper and read eagerly, in a woman’s hand:
+
+“MY DEAR MISS FOX: I have been down here at Seaville on our houseboat,
+the _Lucie_, for several days for a purpose which now is accomplished.
+
+“Already I had my suspicions of you, from a source which I need not
+name. Therefore, when the _Kronprinz_ got into wireless communication
+with the station at Seaville I determined through our own wireless on
+the _Lucie_ to overhear whether there would be any exchange of messages
+between my husband and yourself.
+
+“I was able to overhear the whole thing and I want you to know that
+your secret is no longer a secret from me, and that I have already told
+Mr. Edwards that I know it. You ruin his life by your intimacy which
+you seem to want to keep up, although you know you have no right to do
+it, but you shall not ruin mine.
+
+“I am thoroughly disillusioned now. I have not decided on what steps to
+take, but—”
+
+Only a casual glance was necessary to show me that the writing seemed
+to grow more and more weak as it progressed, and the note stopped
+abruptly, as if the writer had been suddenly interrupted or some new
+idea had occurred to her.
+
+Hastily I tried to figure it out. Lucie Waldon, as everybody knew, was
+a famous beauty, a marvel of charm and daintiness, slender, with big,
+soulful, wistful eyes. Her marriage to Tracy Edwards, the wealthy
+plunger and stockbroker, had been a great social event the year before,
+and it was reputed at the time that Edwards had showered her with
+jewels and dresses to the wonder and talk even of society.
+
+As for Valerie Fox, I knew she had won quick recognition and even fame
+as a dancer in New York during the previous winter, and I recalled
+reading three or four days before that she had just returned on the
+_Kronprinz_ from a trip abroad.
+
+“I don’t suppose you have had time to see Miss Fox,” I remarked. “Where
+is she?”
+
+“At Beach Park now, I think,” replied Waldon, “a resort a few miles
+nearer the city on the south shore, where there is a large colony of
+actors.”
+
+I handed back the letter to Kennedy.
+
+“What do you make of it?” he asked, as he folded it up and put it back
+into his pocket.
+
+“I hardly know what to say,” I replied. “Of course there have been
+rumors, I believe, that all was not exactly like a honeymoon still with
+the Tracy Edwardses.”
+
+“Yes,” returned Waldon slowly, “I know myself that there has been some
+trouble, but nothing definite until I found this letter last night in
+my sister’s room. She never said anything about it either to mother or
+myself. They haven’t been much together during the summer, and last
+night when she disappeared Tracy was in the city. But I hadn’t thought
+much about it before, for, of course, you know he has large financial
+interests that make him keep in pretty close touch with New York and
+this summer hasn’t been a particularly good one on the stock exchange.”
+
+“And,” I put in, “a plunger doesn’t always make the best of husbands.
+Perhaps there is temperament to be reckoned with here.”
+
+“There seem to be a good many things to be reckoned with,” Craig
+considered. “For example, here’s a houseboat, the _Lucie_, a palatial
+affair, cruising about aimlessly, with a beautiful woman on it. She
+gives a little party, in the absence of her husband, to her brother,
+his fiancée and her mother, who visit her from his yacht, the
+_Nautilus_. They break up, those living on the _Lucie_ going to their
+rooms and the rest back to the yacht, which is anchored out further in
+the deeper water of the bay.
+
+“Some time in the middle of the night her maid, Juanita, finds that she
+is not in her room. Her brother is summoned back from his yacht and
+finds that she has left this pathetic, unfinished letter. But otherwise
+there is no trace of her. Her husband is notified and hurries out
+there, but he can find no clue. Meanwhile, Mr. Waldon, in despair,
+hurries down to the city to engage me quietly.”
+
+“You remember I told you,” suggested Waldon, “that my sister hadn’t
+been feeling well for several days. In fact it seemed that the sea air
+wasn’t doing her much good, and some one last night suggested that she
+try the mountains.”
+
+“Had there been anything that would foreshadow the—er—disappearance?”
+asked Kennedy.
+
+“Only as I say, that for two or three days she seemed to be listless,
+to be sinking by slow and easy stages into a sort of vacant, moody
+state of ill health.”
+
+“She had a doctor, I suppose?” I asked.
+
+“Yes, Dr. Jermyn, Tracy’s own personal physician came down from the
+city several days ago.”
+
+“What did he say?”
+
+“He simply said that it was congestion of the lungs. As far as he could
+see there was no apparent cause for it. I don’t think he was very
+enthusiastic about the mountain air idea. The fact is he was like a
+good many doctors under the circumstances, noncommittal—wanted her
+under observation, and all that sort of thing.”
+
+“What’s your opinion?” I pressed Craig. “Do you think she has run
+away?”
+
+“Naturally, I’d rather not attempt to say yet,” Craig replied
+cautiously. “But there are several possibilities. Yes, she might have
+left the houseboat in some other boat, of course. Then there is the
+possibility of accident. It was a hot night. She might have been
+leaning from the window and have lost her balance. I have even thought
+of drugs, that she might have taken something in her despondency and
+have fallen overboard while under the influence of it. Then, of course,
+there are the two deductions that everyone has made already—either
+suicide or murder.”
+
+Waldon had evidently been turning something over in his mind.
+
+“There was a wireless outfit aboard the houseboat,” he ventured at
+length.
+
+“What of that?” I asked, wondering why he was changing the subject so
+abruptly.
+
+“Why, only this,” he replied. “I have been reading about wireless a
+good deal lately, and if the theories of some scientists are correct,
+the wireless age is not without its dangers as well as its wonders. I
+recall reading not long ago of a German professor who says there is no
+essential difference between wireless waves and the X-rays, and we know
+the terrible physical effects of X-rays. I believe he estimated that
+only one three hundred millionth part of the electrical energy
+generated by sending a message from one station to another near by is
+actually used up in transmitting the message. The rest is dispersed in
+the atmosphere. There must be a good deal of such stray electrical
+energy about Seaville. Isn’t it possible that it might hit some one
+somewhere who was susceptible?”
+
+Kennedy said nothing. Waldon’s was at least a novel idea, whether it
+was plausible or not. The only way to test it out, as far as I could
+determine, was to see whether it fitted with the facts after a careful
+investigation of the case itself.
+
+It was still early in the day and the trains were not as crowded as
+they would be later. Consequently our journey was comfortable enough
+and we found ourselves at last at the little vine-covered station at
+Seaville.
+
+One could almost feel that the gay summer colony was in a state of
+subdued excitement. As we left the quaint station and walked down the
+main street to the town wharf where we expected some one would be
+waiting for us, it seemed as if the mysterious disappearance of the
+beautiful Mrs. Edwards had put a damper on the life of the place. In
+the hotels there were knots of people evidently discussing the affair,
+for as we passed we could tell by their faces that they recognized us.
+One or two bowed and would have joined us, if Waldon had given any
+encouragement. But he did not stop, and we kept on down the street
+quickly.
+
+I myself began to feel the spell of mystery about the case as I had not
+felt it among the distractions of the city. Perhaps I imagined it, but
+there even seemed to be something strange about the houseboat which we
+could descry at anchor far down the bay as we approached the wharf.
+
+We were met, as Waldon had arranged, by a high-powered runabout, the
+tender to his own yacht, a slim little craft of mahogany and brass,
+driven like an automobile, and capable of perhaps twenty-five or thirty
+miles an hour. We jumped in and were soon skimming over the waters of
+the bay like a skipping stone.
+
+It was evident that Waldon was much relieved at having been able to
+bring assistance, in which he had as much confidence as he reposed in
+Kennedy. At any rate it was something to be nearing the scene of action
+again.
+
+The _Lucie_ was perhaps seventy feet long and a most attractive craft,
+with a hull yachty in appearance and of a type which could safely make
+long runs along the coast, a stanch, seaworthy boat, of course without
+the speed of the regularly designed yacht, but more than making up in
+comfort for those on board what was lost in that way. Waldon pointed
+out with obvious pride his own trim yacht swinging gracefully at anchor
+a half mile or so away.
+
+As we approached the houseboat I looked her over carefully. One of the
+first things I noticed was that there rose from the roof the primitive
+inverted V aërial of a wireless telegraph. I thought immediately of the
+unfinished letter and its contents, and shaded my eyes as I took a good
+look at the powerful transatlantic station on the spit of sand perhaps
+three or four miles distant, with its tall steel masts of the latest
+inverted L type and the cluster of little houses below, in which the
+operators and the plant were.
+
+Waldon noticed what I was looking at, and remarked, “It’s a wonderful
+station—and well worth a visit, if you have the time—one of the most
+powerful on the coast, I understand.”
+
+“How did the _Lucie_ come to be equipped with wireless?” asked Craig
+quickly. “It’s a little unusual for a private boat.”
+
+“Mr. Edwards had it done when she was built,” explained Waldon. “His
+idea was to use it to keep in touch with the stock market on trips.”
+
+“And it has proved effective?” asked Craig.
+
+“Oh, yes—that is, it was all right last winter when he went on a short
+cruise down in Florida. This summer he hasn’t been on the boat long
+enough to use it much.”
+
+“Who operates it?”
+
+“He used to hire a licensed operator, although I believe the engineer,
+Pedersen, understands the thing pretty well and could use it if
+necessary.”
+
+“Do you think it was Pedersen who used it for Mrs. Edwards?” asked
+Kennedy.
+
+“I really don’t know,” confessed Waldon. “Pedersen denies absolutely
+that he has touched the thing for weeks. I want you to quiz him. I
+wasn’t able to get him to admit a thing.”
+
+
+
+
+CHAPTER VIII
+THE HOUSEBOAT MYSTERY
+
+
+We had by this time swung around to the side of the houseboat. I
+realized as we mounted the ladder that the marine gasoline engine had
+materially changed the old-time houseboat from a mere scow or barge
+with a low flat house on it, moored in a bay or river, and only with
+difficulty and expense towed from one place to another. Now the
+houseboat was really a fair-sized yacht.
+
+The _Lucie_ was built high in order to give plenty of accommodation for
+the living quarters. The staterooms, dining rooms and saloon were
+really rooms, with seven or eight feet of head room, and furnished just
+as one would find in a tasteful and expensive house.
+
+Down in the hull, of course, was the gasoline motor which drove the
+propeller, so that when the owner wanted a change of scene all that was
+necessary was to get up anchor, start the motor and navigate the
+yacht-houseboat to some other harbor.
+
+Edwards himself met us on the deck. He was a tall man, with a red face,
+a man of action, of outdoor life, apparently a hard worker and a hard
+player. It was quite evident that he had been waiting for the return of
+Waldon anxiously.
+
+“You find us considerably upset, Professor Kennedy,” he greeted Craig,
+as his brother-in-law introduced us.
+
+Edwards turned and led the way toward the saloon. As he entered and
+bade us be seated in the costly cushioned wicker chairs I noticed how
+sumptuously it was furnished, and particularly its mechanical piano,
+its phonograph and the splendid hardwood floor which seemed to invite
+one to dance in the cool breeze that floated across from one set of
+open windows to the other. And yet in spite of everything, there was
+that indefinable air of something lacking, as in a house from which the
+woman is gone.
+
+“You were not here last night, I understand,” remarked Kennedy, taking
+in the room at a glance.
+
+“Unfortunately, no,” replied Edwards, “Business has kept me with my
+nose pretty close to the grindstone this summer. Waldon called me up in
+the middle of the night, however, and I started down in my car, which
+enabled me to get here before the first train. I haven’t been able to
+do a thing since I got here except just wait—wait—wait. I confess that
+I don’t know what else to do. Waldon seemed to think we ought to have
+some one down here—and I guess he was right. Anyhow, I’m glad to see
+you.”
+
+I watched Edwards keenly. For the first time I realized that I had
+neglected to ask Waldon whether he had seen the unfinished letter. The
+question was unnecessary. It was evident that he had not.
+
+“Let me see, Waldon, if I’ve got this thing straight,” Edwards went on,
+pacing restlessly up and down the saloon. “Correct me if I haven’t.
+Last night, as I understand it, there was a sort of little family party
+here, you and Miss Verrall and your mother from the _Nautilus_, and
+Mrs. Edwards and Dr. Jermyn.”
+
+“Yes,” replied Waldon with, I thought, a touch of defiance at the words
+“family party.” He paused as if he would have added that the _Nautilus_
+would have been more congenial, anyhow, then added, “We danced a little
+bit, all except Lucie. She said she wasn’t feeling any too well.”
+
+Edwards had paused by the door. “If you’ll excuse me a minute,” he
+said, “I’ll call Jermyn and Mrs. Edwards’ maid, Juanita. You ought to
+go over the whole thing immediately, Professor Kennedy.”
+
+“Why didn’t you say anything about the letter to him?” asked Kennedy
+under his breath.
+
+“What was the use?” returned Waldon. “I didn’t know how he’d take it.
+Besides, I wanted your advice on the whole thing. Do you want to show
+it to him?”
+
+“Perhaps it’s just as well,” ruminated Kennedy. “It may be possible to
+clear the thing up without involving anybody’s name. At any rate, some
+one is coming down the passage this way.”
+
+Edwards entered with Dr. Jermyn, a clean-shaven man, youthful in
+appearance, yet approaching middle age. I had heard of him before. He
+had studied several years abroad and had gained considerable reputation
+since his return to America.
+
+Dr. Jermyn shook hands with us cordially enough, made some passing
+comment on the tragedy, and stood evidently waiting for us to disclose
+our hands.
+
+“You have been Mrs. Edwards’ physician for some time, I believe?”
+queried Kennedy, fencing for an opening.
+
+“Only since her marriage,” replied the doctor briefly.
+
+“She hadn’t been feeling well for several days, had she?” ventured
+Kennedy again.
+
+“No,” replied Dr. Jermyn quickly. “I doubt whether I can add much to
+what you already know. I suppose Mr. Waldon has told you about her
+illness. The fact is, I suppose her maid Juanita will be able to tell
+you really more than I can.”
+
+I could not help feeling that Dr. Jermyn showed a great deal of
+reluctance in talking.
+
+“You have been with her several days, though, haven’t you?”
+
+“Four days, I think. She was complaining of feeling nervous and
+telegraphed me to come down here. I came prepared to stay over night,
+but Mr. Edwards happened to run down that day, too, and he asked me if
+I wouldn’t remain longer. My practice in the summer is such that I can
+easily leave it with my assistant in the city, so I agreed. Really,
+that is about all I can say. I don’t know yet what was the matter with
+Mrs. Edwards, aside from the nervousness which seemed to be of some
+time standing.”
+
+He stood facing us, thoughtfully stroking his chin, as a very pretty
+and petite maid nervously entered and stood facing us in the doorway.
+
+“Come in, Juanita,” encouraged Edwards. “I want you to tell these
+gentlemen just what you told me about discovering that Madame had
+gone—and anything else that you may recall now.”
+
+“It was Juanita who discovered that Madame was gone, you know,” put in
+Waldon.
+
+“How did you discover it?” prompted Craig.
+
+“It was very hot,” replied the maid, “and often on hot nights I would
+come in and fan Madame since she was so wakeful. Last night I went to
+the door and knocked. There was no reply. I called to her, ‘Madame,
+madame.’ Still there was no answer. The worst I supposed was that she
+had fainted. I continued to call.”
+
+“The door was locked?” inquired Kennedy.
+
+“Yes, sir. My call aroused the others on the boat. Dr. Jermyn came and
+he broke open the door with his shoulder. But the room was empty.
+Madame was gone.”
+
+“How about the windows?” asked Kennedy.
+
+“Open. They were always open these nights. Sometimes Madame would sit
+by the window when there was not much breeze.”
+
+“I should like to see the room,” remarked Craig, with an inquiring
+glance at Edwards.
+
+“Certainly,” he answered, leading the way down a corridor.
+
+Mrs. Edwards’ room was on the starboard side, with wide windows instead
+of portholes. It was furnished magnificently and there was little about
+it that suggested the nautical, except the view from the window.
+
+“The bed had not been slept in,” Edwards remarked as we looked about
+curiously.
+
+Kennedy walked over quickly to the wide series of windows before which
+was a leather-cushioned window seat almost level with the window,
+several feet above the level of the water. It was by this window,
+evidently, that Juanita meant that Mrs. Edwards often sat. It was a
+delightful position, but I could readily see that it would be
+comparatively easy for anyone accidentally or purposely to fall.
+
+“I think myself,” Waldon remarked to Kennedy, “that it must have been
+from the open window that she made her way to the outside. It seems
+that all agree that the door was locked, while the window was wide
+open.”
+
+“There had been no sound—no cry to alarm you?” shot out Kennedy
+suddenly to Juanita.
+
+“No, sir, nothing. I could not sleep myself, and I thought of Madame.”
+
+“You heard nothing?” he asked of Dr. Jermyn.
+
+“Nothing until I heard the maid call,” he replied briefly.
+
+Mentally I ran over again Kennedy’s first list of possibilities—taken
+off by another boat, accident, drugs, suicide, murder.
+
+Was there, I asked myself, sufficient reason for suicide? The letter
+seemed to me to show too proud a spirit for that. In fact the last
+sentence seemed to show that she was contemplating the surest method of
+revenge, rather than surrender. As for accident, why should a person
+fall overboard from a large houseboat into a perfectly calm harbor?
+Then, too, there had been no outcry. Somehow, I could not seem to fit
+any of the theories in with the facts. Evidently it was like many
+another case, one in which we, as yet, had insufficient data for a
+conclusion.
+
+Suddenly I recalled the theory that Waldon himself had advanced
+regarding the wireless, either from the boat itself or from the
+wireless station. For the moment, at least, it seemed plausible that
+she might have been seated at the window, that she might have been
+affected by escaped wireless, or by electrolysis. I knew that some
+physicians had described a disease which they attributed to wireless, a
+sort of anemia with a marked diminution in the number of red corpuscles
+in the blood, due partly to the over etherization of the air by reason
+of the alternating currents used to generate the waves.
+
+“I should like now to inspect the little wireless plant you have here
+on the _Lucie_,” remarked Kennedy. “I noticed the mast as we were
+approaching a few minutes ago.”
+
+I had turned at the sound of his voice in time to catch Edwards and Dr.
+Jermyn eyeing each other furtively. Did they know about the letter,
+after all, I wondered? Was each in doubt about just how much the other
+knew?
+
+There was no time to pursue these speculations. “Certainly,” agreed Mr.
+Edwards promptly, leading the way.
+
+Kennedy seemed keenly interested in inspecting the little wireless
+plant, which was of a curious type and not exactly like any that I had
+seen before.
+
+“Wireless apparatus,” he remarked, as he looked it over, “is divided
+into three parts, the source of power whether battery or dynamo, the
+making and sending of wireless waves, including the key, spark,
+condenser and tuning coil, and the receiving apparatus, head
+telephones, antennae, ground and detector.”
+
+Pedersen, the engineer, came in while we were looking the plant over,
+but seemed uncommunicative to all Kennedy’s efforts to engage him in
+conversation.
+
+“I see,” remarked Kennedy, “that it is a very compact system with
+facilities for a quick change from one wave length to another.”
+
+“Yes,” grunted Pedersen, as averse to talking, evidently, as others on
+the _Lucie_.
+
+“Spark gap, quenched type,” I heard Kennedy mutter almost to himself,
+with a view to showing Pedersen that he knew something about it. “Break
+system relay—operator can overhear any interference while
+transmitting—transformation by a single throw of a six-point switch
+which tunes the oscillating and open circuits to resonance. Very
+clever—very efficient. By the way, Pedersen, are you the only person
+aboard who can operate this?”
+
+“How should I know?” he answered almost surlily.
+
+“You ought to know, if anybody,” answered Kennedy unruffled. “I know
+that it has been operated within the past few days.”
+
+Pedersen shrugged his shoulders. “You might ask the others aboard,” was
+all he said. “Mr. Edwards pays me to operate it only for himself, when
+he has no other operator.”
+
+Kennedy did not pursue the subject, evidently from fear of saying too
+much just at present.
+
+“I wonder if there is anyone else who could have operated it,” said
+Waldon, as we mounted again to the deck.
+
+“I don’t know,” replied Kennedy, pausing on the way up. “You haven’t a
+wireless on the _Nautilus_, have you?”
+
+Waldon shook his head. “Never had any particular use for it myself,” he
+answered.
+
+“You say that Miss Verrall and her mother have gone back to the city?”
+pursued Kennedy, taking care that as before the others were out of
+earshot.
+
+“Yes.”
+
+“I’d like to stay with you tonight, then,” decided Kennedy. “Might we
+go over with you now? There doesn’t seem to be anything more I can do
+here, unless we get some news about Mrs. Edwards.”
+
+Waldon seemed only too glad to agree, and no one on the _Lucie_
+insisted on our staying.
+
+We arrived at the _Nautilus_ a few minutes later, and while we were
+lunching Kennedy dispatched the tender to the Marconi station with a
+note.
+
+It was early in the afternoon when the tender returned with several
+packages and coils of wire. Kennedy immediately set to work on the
+_Nautilus_ stretching out some of the wire.
+
+“What is it you are planning?” asked Waldon, to whom every action of
+Kennedy seemed to be a mystery of the highest interest.
+
+“Improvising my own wireless,” he replied, not averse to talking to the
+young man to whom he seemed to have taken a fancy. “For short
+distances, you know, it isn’t necessary to construct an aërial pole or
+even to use outside wires to receive messages. All that is needed is to
+use just a few wires stretched inside a room. The rest is just the
+apparatus.”
+
+I was quite as much interested as Waldon. “In wireless,” he went on,
+“the signals are not sent in one direction, but in all, so that a
+person within range of the ethereal disturbance can get them if only he
+has the necessary receiving apparatus. This apparatus need not be so
+elaborate and expensive as used to be thought needful if a sensitive
+detector is employed, and I have sent over to the station for a new
+piece of apparatus which I knew they had in almost any Marconi station.
+Why, I’ve got wireless signals using only twelve feet of number
+eighteen copper wire stretched across a room and grounded with a water
+pipe. You might even use a wire mattress on an iron bedstead.”
+
+“Can’t they find out by—er, interference?” I asked, repeating the term
+I had so often heard.
+
+Kennedy laughed. “No, not for radio apparatus which merely receives
+radiograms and is not equipped for sending. I am setting up only one
+side of a wireless outfit here. All I want to do is to hear what is
+being said. I don’t care about saying anything.”
+
+He unwrapped another package which had been loaned to him by the radio
+station and we watched him curiously as he tested it and set it up.
+Some parts of it I recognized such as the very sensitive microphone,
+and another part I could have sworn was a phonograph cylinder, though
+Craig was so busy testing his apparatus that now we could not ask
+questions.
+
+It was late in the afternoon when he finished, and we had just time to
+run up to the dock at Seaville and stop off at the _Lucie_ to see if
+anything had happened in the intervening hours before dinner. There was
+nothing, except that I found time to file a message to the _Star_ and
+meet several fellow newspaper men who had been sent down by other
+papers on the chance of picking up a good story.
+
+We had the _Nautilus_ to ourselves, and as she was a very comfortable
+little craft, we really had a very congenial time, a plunge over her
+side, a good dinner, and then a long talk out on deck under the stars,
+in which we went over every phase of the case. As we discussed it,
+Waldon followed keenly, and it was quite evident from his remarks that
+he had come to the conclusion that Dr. Jermyn at least knew more than
+he had told about the case.
+
+Still, the day wore away with no solution yet of the mystery.
+
+
+
+
+CHAPTER IX
+THE RADIO DETECTIVE
+
+
+It was early the following morning when a launch drew up beside the
+_Nautilus_. In it were Edwards and Dr. Jermyn, wildly excited.
+
+“What’s the matter?” called out Waldon.
+
+“They—they have found the body,” Edwards blurted out.
+
+Waldon paled and clutched the rail. He had thought the world of his
+sister, and not until the last moment had he given up hope that perhaps
+she might be found to have disappeared in some other way than had
+become increasingly evident.
+
+“Where?” cried Kennedy. “Who?”
+
+“Over on Ten Mile Beach,” answered Edwards. “Some fishermen who had
+been out on a cruise and hadn’t heard the story. They took the body to
+town, and there it was recognized. They sent word out to us
+immediately.”
+
+Waldon had already spun the engine of his tender, which was about the
+fastest thing afloat about Seaville, had taken Edwards over, and we
+were off in a cloud of spray, the nose of the boat many inches above
+the surface of the water.
+
+In the little undertaking establishment at Seaville lay the body of the
+beautiful young matron about whom so much anxiety had been felt. I
+could not help thinking what an end was this for the incomparable
+beauty. At the very height of her brief career the poor little woman’s
+life had been suddenly snuffed out. But by what? The body had been
+found, but the mystery had been far from solved.
+
+As Kennedy bent over the body, I heard him murmur to himself, “She had
+everything—everything except happiness.”
+
+“Was it drowning that caused her death?” asked Kennedy of the local
+doctor, who also happened to be coroner and had already arrived on the
+scene.
+
+The doctor shook his head. “I don’t know,” he said doubtfully. “There
+was congestion of the lungs—but I—I can’t say but what she might have
+been dead before she fell or was thrown into the water.”
+
+Dr. Jermyn stood on one side, now and then putting in a word, but for
+the most part silent unless spoken to. Kennedy, however, was making a
+most minute examination.
+
+As he turned the beautiful head, almost reverently, he saw something
+that evidently attracted his attention. I was standing next to him and,
+between us, I think we cut off the view of the others. There on the
+back of the neck, carefully, had been smeared something transparent,
+almost skin-like, which had easily escaped the attention of the rest.
+
+Kennedy tried to pick it off, but only succeeded in pulling off a very
+minute piece to which the flesh seemed to adhere.
+
+“That’s queer,” he whispered to me. “Water, naturally, has no effect on
+it, else it would have been washed off long before. Walter,” he added,
+“just slip across the street quietly to the drug store and get me a
+piece of gauze soaked with acetone.”
+
+As quickly and unostentatiously as I could I did so and handed him the
+wet cloth, contriving at the same time to add Waldon to our barrier,
+for I could see that Kennedy was anxious to be observed as little as
+possible.
+
+“What is it?” I whispered, as he rubbed the transparent skin-like stuff
+off, and dropped the gauze into his pocket.
+
+“A sort of skin varnish,” he remarked under his breath, “waterproof and
+so adhesive that it resists pulling off even with a knife without
+taking the cuticle with it.”
+
+Beneath, as the skin varnish slowly dissolved under his gentle rubbing,
+he had disclosed several very small reddish spots, like little cuts
+that had been made by means of a very sharp instrument. As he did so,
+he gave them a hasty glance, turned the now stony beautiful head
+straight again, stood up, and resumed his talk with the coroner, who
+was evidently getting more and more bewildered by the case.
+
+Edwards, who had completed the arrangements with the undertaker for the
+care of the body as soon as the coroner released it, seemed completely
+unnerved.
+
+“Jermyn,” he said to the doctor, as he turned away and hid his eyes, “I
+can’t stand this. The undertaker wants some stuff from the—er—boat,”
+his voice broke over the name which had been hers. “Will you get it for
+me? I’m going up to a hotel here, and I’ll wait for you there. But I
+can’t go out to the boat—yet.”
+
+“I think Mr. Waldon will be glad to take you out in his tender,”
+suggested Kennedy. “Besides, I feel that I’d like a little fresh air as
+a bracer, too, after such a shock.”
+
+“What were those little cuts?” I asked as Waldon and Dr. Jermyn
+preceded us through the crowd outside to the pier.
+
+“Some one,” he answered in a low tone, “has severed the pneumogastric
+nerves.”
+
+“The pneumogastric nerves?” I repeated.
+
+“Yes, the vagus or wandering nerve, the so-called tenth cranial nerve.
+Unlike the other cranial nerves, which are concerned with the special
+senses or distributed to the skin and muscles of the head and neck, the
+vagus, as its name implies, strays downward into the chest and abdomen
+supplying branches to the throat, lungs, heart and stomach and forms an
+important connecting link between the brain and the sympathetic nervous
+system.”
+
+We had reached the pier, and a nod from Kennedy discouraged further
+conversation on the subject.
+
+A few minutes later we had reached the _Lucie_ and gone up over her
+side. Kennedy waited until Jermyn had disappeared into the room of Mrs.
+Edwards to get what the undertaker had desired. A moment and he had
+passed quietly into Dr. Jermyn’s own room, followed by me. Several
+quick glances about told him what not to waste time over, and at last
+his eye fell on a little portable case of medicines and surgical
+instruments. He opened it quickly and took out a bottle of golden
+yellow liquid.
+
+Kennedy smelled it, then quickly painted some on the back of his hand.
+It dried quickly, like an artificial skin. He had found a bottle of
+skin varnish in Dr. Jermyn’s own medicine chest!
+
+We hurried back to the deck, and a few minutes later the doctor
+appeared with a large package.
+
+“Did you ever hear of coating the skin by a substance which is
+impervious to water, smooth and elastic?” asked Kennedy quietly as
+Waldon’s tender sped along back to Seaville.
+
+“Why—er, yes,” he said frankly, raising his eyes and looking at Craig
+in surprise. “There have been a dozen or more such substances. The best
+is one which I use, made of pyroxylin, the soluble cotton of commerce,
+dissolved in amyl acetate and acetone with some other substances that
+make it perfectly sterile. Why do you ask?”
+
+“Because some one has used a little bit of it to cover a few slight
+cuts on the back of the neck of Mrs. Edwards.”
+
+“Indeed?” he said simply, in a tone of mild surprise.
+
+“Yes,” pursued Kennedy. “They seem to me to be subcutaneous incisions
+of the neck with a very fine scalpel dividing the two great
+pneumogastric nerves. Of course you know what that would mean—the
+victim would pass away naturally by slow and easy stages in three or
+four days, and all that would appear might be congestion of the lungs.
+They are delicate little punctures and elusive nerves to locate, but
+after all it might be done as painlessly, as simply and as safely as a
+barber might remove some dead hairs. A country coroner might easily
+pass over such evidence at an autopsy—especially if it was concealed by
+skin varnish.”
+
+I was surprised at the frankness with which Kennedy spoke, but
+absolutely amazed at the coolness of Jermyn. At first he said
+absolutely nothing. He seemed to be as set in his reticence as he had
+been when we first met.
+
+I watched him narrowly. Waldon, who was driving the boat, had not heard
+what was said, but I had, and I could not conceive how anyone could
+take it so calmly.
+
+Finally Jermyn turned to Kennedy and looked him squarely in the eye.
+“Kennedy,” he said slowly, “this is extraordinary—most extraordinary,”
+then, pausing, added, “if true.”
+
+“There can be no doubt of the truth,” replied Kennedy, eyeing Dr.
+Jermyn just as squarely.
+
+“What do you propose to do about it?” asked the doctor.
+
+“Investigate,” replied Kennedy simply. “While Waldon takes these things
+up to the undertaker’s, we may as well wait here in the boat. I want
+him to stop on the way back for Mr. Edwards. Then we shall go out to
+the _Lucie_. He must go, whether he likes it or not.”
+
+It was indeed a most peculiar situation as Kennedy and I sat in the
+tender with Dr. Jermyn waiting for Waldon to return with Edwards. Not a
+word was spoken.
+
+The tenseness of the situation was not relieved by the return of Waldon
+with Edwards. Waldon seemed to realize without knowing just what it
+was, that something was about to happen. He drove his boat back to the
+_Lucie_ again in record time. This was Kennedy’s turn to be reticent.
+Whatever it was he was revolving in his mind, he answered in scarcely
+more than monosyllables whatever questions were put to him.
+
+“You are not coming aboard?” inquired Edwards in surprise as he and
+Jermyn mounted the steps of the houseboat ladder, and Kennedy remained
+seated in the tender.
+
+“Not yet,” replied Craig coolly.
+
+“But I thought you had something to show me. Waldon told me you had.”
+
+“I think I shall have in a short time,” returned Kennedy. “We shall be
+back immediately. I’m just going to ask Waldon to run over to the
+_Nautilus_ for a few minutes. We’ll tow back your launch, too, in case
+you need it.”
+
+Waldon had cast off obediently.
+
+“There’s one thing sure,” I remarked. “Jermyn can’t get away from the
+_Lucie_ until we return—unless he swims.”
+
+Kennedy did not seem to pay much attention to the remark, for his only
+reply was: “I’m taking a chance by this maneuvering, but I think it
+will work out that I am correct. By the way, Waldon, you needn’t put on
+so much speed. I’m in no great hurry to get back. Half an hour will be
+time enough.”
+
+“Jermyn? What did you mean by Jermyn?” asked Waldon, as we climbed to
+the deck of the _Nautilus_.
+
+He had evidently learned, as I had, that it was little use to try to
+quiz Kennedy until he was ready to be questioned and had decided to try
+it on me.
+
+I had nothing to conceal and I told him quite fully all that I knew.
+Actually, I believe if Jermyn had been there, it would have taken both
+Kennedy and myself to prevent violence. As it was I had a veritable
+madman to deal with while Kennedy gathered up leisurely the wireless
+outfit he had installed on the deck of Waldon’s yacht. It was only by
+telling him that I would certainly demand that Kennedy leave him behind
+if he did not control his feelings that I could calm him before Craig
+had finished his work on the yacht.
+
+Waldon relieved himself by driving the tender back at top speed to the
+_Lucie_, and now it seemed that Kennedy had no objection to traveling
+as fast as the many-cylindered engine was capable of going.
+
+As we entered the saloon of the houseboat, I kept close watch over
+Waldon.
+
+Kennedy began by slipping a record on the phonograph in the corner of
+the saloon, then facing us and addressing Edwards particularly.
+
+“You may be interested to know, Mr. Edwards,” he said, “that your
+wireless outfit here has been put to a use for which you never intended
+it.”
+
+No one said anything, but I am sure that some one in the room then for
+the first time began to suspect what was coming.
+
+“As you know, by the use of an aërial pole, messages may be easily
+received from any number of stations,” continued Craig. “Laws, rules
+and regulations may be adopted to shut out interlopers and plug
+busybody ears, but the greater part of whatever is transmitted by the
+Hertzian waves can be snatched down by other wireless apparatus.
+
+“Down below, in that little room of yours,” went on Craig, “might sit
+an operator with his ear-phone clamped to his head, drinking in the
+news conveyed surely and swiftly to him through the wireless
+signals—plucking from the sky secrets of finance and,” he added,
+leaning forward, “love.”
+
+In his usual dramatic manner Kennedy had swung his little audience
+completely with him.
+
+“In other words,” he resumed, “it might be used for eavesdropping by a
+wireless wiretapper. Now,” he concluded, “I thought that if there was
+any radio detective work being done, I might as well do some, too.”
+
+He toyed for a moment with the phonograph record. “I have used,” he
+explained, “Marconi’s radiotelephone, because in connection with his
+receivers Marconi uses phonographic recorders and on them has captured
+wireless telegraph signals over hundreds of miles.
+
+“He has found that it is possible to receive wireless signals, although
+ordinary records are not loud enough, by using a small microphone on
+the repeating diaphragm and connected with a loud-speaking telephone.
+The chief difficulty was to get a microphone that would carry a
+sufficient current without burning up. There were other difficulties,
+but they have been surmounted and now wireless telegraph messages may
+be automatically recorded and made audible.”
+
+Kennedy started the phonograph, running it along, stopping it, taking
+up the record at a new point.
+
+“Listen,” he exclaimed at length, “there’s something interesting, the
+WXY call—Seaville station—from some one on the _Lucie_ only a few
+minutes ago, sending a message to be relayed by Seaville to the station
+at Beach Park. It seems impossible, but buzzing and ticking forth is
+this message from some one off this very houseboat. It reads: “Miss
+Valerie Fox, Beach Park. I am suspected of the murder of Mrs. Edwards.
+I appeal to you to help me. You must allow me to tell the truth about
+the messages I intercepted for Mrs. Edwards which passed between
+yourself on the ocean and Mr. Edwards in New York via Seaville. You
+rejected me and would not let me save you. Now you must save me.”
+
+Kennedy paused, then added, “The message is signed by Dr. Jermyn!”
+
+At once I saw it all. Jermyn had been the unsuccessful suitor for Miss
+Fox’s affections. But before I could piece out the rest of the tragic
+story, Kennedy had started the phonograph record at an earlier point
+which he had skipped for the present.
+
+“Here’s another record—a brief one—also to Valerie Fox from the
+houseboat: ‘Refuse all interviews. Deny everything. Will see you as
+soon as present excitement dies down.’”
+
+Before Kennedy could finish, Waldon had leaped forward, unable longer
+to control his feelings. If Kennedy had not seized his arm, I verily
+believe he would have cast Dr. Jermyn into the bay into which his
+sister had fallen two nights before in her terribly weakened condition.
+
+“Waldon,” cried Kennedy, “for God’s sake, man—wait! Don’t you
+understand? The second message is signed Tracy Edwards.”
+
+It came as quite as much a shock of surprise to me as to Waldon.
+
+“Don’t you understand?” he repeated. “Your sister first learned from
+Dr. Jermyn what was going on. She moved the _Lucie_ down here near
+Seaville in order to be near the wireless station when the ship bearing
+her rival, Valerie Fox, got in touch with land. With the help of Dr.
+Jermyn she intercepted the wireless messages from the _Kronprinz_ to
+the shore—between her husband and Valerie Fox.”
+
+Kennedy was hurrying on now to his irresistible conclusion. “She found
+that he was infatuated with the famous stage beauty, that he was
+planning to marry another, her rival. She accused him of it, threatened
+to defeat his plans. He knew she knew his unfaithfulness. Instead of
+being your sister’s murderer, Dr. Jermyn was helping her get the
+evidence that would save both her and perhaps win Miss Fox back to
+himself.”
+
+Kennedy had turned sharply on Edwards.
+
+“But,” he added, with a glance that crushed any lingering hope that the
+truth had been concealed, “the same night that Dr. Jermyn arrived here,
+you visited your wife. As she slept you severed the nerves that meant
+life or death to her. Then you covered the cuts with the preparation
+which you knew Dr. Jermyn used. You asked him to stay, while you went
+away, thinking that when death came you would have a perfect
+alibi—perhaps a scapegoat. Edwards, the radio detective convicts you!”
+
+
+
+
+CHAPTER X
+THE CURIO SHOP
+
+
+Edwards crumpled up as Kennedy and I faced him. There was no escape. In
+fact our greatest difficulty was to protect him from Waldon.
+
+Kennedy’s work in the case was over when we had got Edwards ashore and
+in the hands of the authorities. But mine had just begun and it was
+late when I got my story on the wire for the _Star_.
+
+I felt pretty tired and determined to make up for it by sleeping the
+next day. It was no use, however.
+
+“Why, what’s the matter, Mrs. Northrop?” I heard Kennedy ask as he
+opened our door the next morning, just as I had finished dressing.
+
+He had admitted a young woman, who greeted us with nervous,
+wide-staring eyes.
+
+“It’s—it’s about Archer,” she cried, sinking into the nearest chair and
+staring from one to the other of us.
+
+She was the wife of Professor Archer Northrop, director of the
+archeological department at the university. Both Craig and I had known
+her ever since her marriage to Northrop, for she was one of the most
+attractive ladies in the younger set of the faculty, to which Craig
+naturally belonged. Archer had been of the class below us in the
+university. We had hazed him, and out of the mild hazing there had,
+strangely enough, grown a strong friendship.
+
+I recollected quickly that Northrop, according to last reports, had
+been down in the south of Mexico on an archeological expedition. But
+before I could frame, even in my mind, the natural question in a form
+that would not alarm his wife further, Kennedy had it on his lips.
+
+“No bad news from Mitla, I hope?” he asked gently, recalling one of the
+main working stations chosen by the expedition and the reported
+unsettled condition of the country about it. She looked up quickly.
+
+“Didn’t you know—he—came back from Vera Cruz yesterday?” she asked
+slowly, then added, speaking in a broken tone, “and—he
+seems—suddenly—to have disappeared. Oh, such a terrible night of worry!
+No word—and I called up the museum, but Doctor Bernardo, the curator,
+had gone, and no one answered. And this morning—I couldn’t stand it any
+longer—so I came to you.”
+
+“You have no idea, I suppose, of anything that was weighing on his
+mind?” suggested Kennedy.
+
+“No,” she answered promptly.
+
+In default of any further information, Kennedy did not pursue this line
+of questioning. I could not determine from his face or manner whether
+he thought the matter might involve another than Mrs. Northrop, or,
+perhaps, something connected with the unsettled condition of the
+country from which her husband had just arrived.
+
+“Have you any of the letters that Archer wrote home?” asked Craig, at
+length.
+
+“Yes,” she replied eagerly, taking a little packet from her handbag. “I
+thought you might ask that. I brought them.”
+
+“You are an ideal client,” commented Craig encouragingly, taking the
+letters. “Now, Mrs. Northrop, be brave. Trust me to run this thing
+down, and if you hear anything let me know immediately.”
+
+She left us a moment later, visibly relieved.
+
+Scarcely had she gone when Craig, stuffing the letters into his pocket
+unread, seized his hat, and a moment later was striding along toward
+the museum with his habitual rapid, abstracted step which told me that
+he sensed a mystery.
+
+In the museum we met Doctor Bernardo, a man slightly older than
+Northrop, with whom he had been very intimate. He had just arrived and
+was already deeply immersed in the study of some new and beautiful
+colored plates from the National Museum of Mexico City.
+
+“Do you remember seeing Northrop here yesterday afternoon?” greeted
+Craig, without explaining what had happened.
+
+“Yes,” he answered promptly. “I was here with him until very late. At
+least, he was in his own room, working hard, when I left.”
+
+“Did you see him go?”
+
+“Why—er—no,” replied Bernardo, as if that were a new idea. “I left him
+here—at least, I didn’t see him go out.”
+
+Kennedy tried the door of Northrop’s room, which was at the far end, in
+a corner, and communicated with the hall only through the main floor of
+the museum. It was locked. A pass-key from the janitor quickly opened
+it.
+
+Such a sight as greeted us, I shall never forget. There, in his big
+desk-chair, sat Northrop, absolutely rigid, the most horribly contorted
+look on his features that I have ever seen—half of pain, half of fear,
+as if of something nameless.
+
+Kennedy bent over. His hands were cold.
+
+Northrop had been dead at least twelve hours, perhaps longer. All night
+the deserted museum had guarded its terrible secret.
+
+As Craig peered into his face, he saw, in the fleshy part of the neck,
+just below the left ear, a round red mark, with just a drop or two of
+now black coagulated blood in the center. All around we could see a
+vast amount of miscellaneous stuff, partly unpacked, partly just
+opened, and waiting to be taken out of the wrappings by the now
+motionless hands.
+
+“I suppose you are more or less familiar with what Northrop brought
+back?” asked Kennedy of Bernardo, running his eye over the material in
+the room.
+
+“Yes, reasonably,” answered Bernardo. “Before the cases arrived from
+the wharf, he told me in detail what he had managed to bring up with
+him.”
+
+“I wish, then, that you would look it over and see if there is anything
+missing,” requested Craig, already himself busy in going over the room
+for other evidence.
+
+Doctor Bernardo hastily began taking a mental inventory of the stuff.
+While they worked, I tried vainly to frame some theory which would
+explain the startling facts we had so suddenly discovered.
+
+Mitla, I knew, was south of the city of Oaxaca, and there, in its
+ruined palaces, was the crowning achievement of the old Zapotec kings.
+No ruins in America were more elaborately ornamented or richer in lore
+for the archeologist.
+
+Northrop had brought up porphyry blocks with quaint grecques and much
+hieroglyphic painting. Already unpacked were half a dozen copper axes,
+some of the first of that particular style that had ever been brought
+to the United States. Besides the sculptured stones and the mosaics
+were jugs, cups, vases, little gods, sacrificial stones—enough, almost,
+to equip a new alcove in the museum.
+
+Before Northrop was an idol, a hideous thing on which frogs and snakes
+squatted and coiled. It was a fitting piece to accompany the gruesome
+occupant of the little room in his long, last vigil. In fact, it almost
+sent a shudder over me, and if I had been inclined to the
+superstitious, I should certainly have concluded that this was
+retribution for having disturbed the _lares_ and _penates_ of a dead
+race.
+
+Doctor Bernardo was going over the material a second time. By the look
+on his face, even I could guess that something was missing.
+
+“What is it?” asked Craig, following the curator closely.
+
+“Why,” he answered slowly, “there was an inscription—we were looking at
+it earlier in the day—on a small block of porphyry. I don’t see it.”
+
+He paused and went back to his search before we could ask him further
+what he thought the inscription was about.
+
+I thought nothing myself at the time of his reticence, for Kennedy had
+gone over to a window back of Northrop and to the left. It was fully
+twenty feet from the downward slope of the campus there, and, as he
+craned his neck out, he noted that the copper leader of the rain pipe
+ran past it a few feet away.
+
+I, too, looked out. A thick group of trees hid the window from the
+avenue beyond the campus wall, and below us, at a corner of the
+building, was a clump of rhododendrons. As Craig bent over the sill, he
+whipped out a pocket lens.
+
+A moment later he silently handed the glass to me. As nearly as I could
+make out, there were five marks on the dust of the sill.
+
+“Finger-prints!” I exclaimed. “Some one has been clinging to the edge
+of the ledge.”
+
+“In that case,” Craig observed quietly, “there would have been only
+four prints.”
+
+I looked again, puzzled. The prints were flat and well separated.
+
+“No,” he added, “not finger-prints—toe-prints.”
+
+“Toe-prints?” I echoed.
+
+Before he could reply, Craig had dashed out of the room, around, and
+under the window. There, he was carefully going over the soft earth
+around the bushes below.
+
+“What are you looking for?” I asked, joining him.
+
+“Some one—perhaps two—has been here,” he remarked, almost under his
+breath. “One, at least, has removed his shoes. See those shoe-prints up
+to this point? The print of a boot-heel in soft earth shows the
+position and contour of every nail head. Bertillon has made a
+collection of such nails, certain types, sizes, and shapes used in
+certain boots, showing often what country the shoes came from. Even the
+number and pattern are significant. Some factories use a fixed number
+of nails and arrange them in a particular manner. I have made my own
+collection of such prints in this country. These were American shoes.
+Perhaps the clue will not lead us anywhere, though, for I doubt whether
+it was an American foot.”
+
+Kennedy continued to study the marks.
+
+“He removed his shoes—either to help in climbing or to prevent
+noise—ah—here’s the foot! Strange—see how small it is—and broad, how
+prehensile the toes—almost like fingers. Surely that foot could never
+have been encased in American shoes all its life. I shall make plaster
+casts of these, to preserve later.”
+
+He was still scouting about on hands and knees in the dampness of the
+rhododendrons. Suddenly he reached his long arm in among the shrubs and
+picked up a little reed stick. On the end of it was a small cylinder of
+buff brown.
+
+He looked at it curiously, dug his nail into the soft mass, then rubbed
+his nail over the tip of his tongue gingerly.
+
+With a wry face, as if the taste were extremely acrid, he moistened his
+handkerchief and wiped off his tongue vigorously.
+
+“Even that minute particle that was on my nail makes my tongue tingle
+and feel numb,” he remarked, still rubbing. “Let us go back again. I
+want to see Bernardo.”
+
+“Had he any visitors during the day?” queried Kennedy, as he reentered
+the ghastly little room, while the curator stood outside, completely
+unnerved by the tragedy which had been so close to him without his
+apparently knowing it. Kennedy was squeezing out from the little wound
+on Northrop’s neck a few drops of liquid on a sterilized piece of
+glass.
+
+“No; no one,” Bernardo answered, after a moment.
+
+“Did you see anyone in the museum who looked suspicious?” asked
+Kennedy, watching Bernardo’s face keenly.
+
+“No,” he hesitated. “There were several people wandering about among
+the exhibits, of course. One, I recall, late in the afternoon, was a
+little dark-skinned woman, rather good-looking.”
+
+“A Mexican?”
+
+“Yes, I should say so. Not of Spanish descent, though. She was rather
+of the Indian type. She seemed to be much interested in the various
+exhibits, asked me several questions, very intelligently, too. Really,
+I thought she was trying to—er—flirt with me.”
+
+He shot a glance at Craig, half of confession, half of embarrassment.
+
+“And—oh, yes—there was another—a man, a little man, as I recall, with
+shaggy hair. He looked like a Russian to me. I remember, because he
+came to the door, peered around hastily, and went away. I thought he
+might have got into the wrong part of the building and went to direct
+him right—but before I could get out into the hall, he was gone. I
+remember, too, that, as I turned, the woman had followed me and soon
+was asking other questions—which, I will admit—I was glad to answer.”
+
+“Was Northrop in his room while these people were here?”
+
+“Yes; he had locked the door so that none of the students or visitors
+could disturb him.”
+
+“Evidently the woman was diverting your attention while the man entered
+Northrop’s room by the window,” ruminated Craig, as we stood for a
+moment in the outside doorway.
+
+He had already telephoned to our old friend Doctor Leslie, the coroner,
+to take charge of the case, and now was ready to leave. The news had
+spread, and the janitor of the building was waiting to lock the campus
+door to keep back the crowd of students and others.
+
+Our next duty was the painful one of breaking the news to Mrs.
+Northrop. I shall pass it over. Perhaps no one could have done it more
+gently than Kennedy. She did not cry. She was simply dazed. Fortunately
+her mother was with her, had been, in fact, ever since Northrop had
+gone on the expedition.
+
+“Why should anyone want to steal tablets of old Mixtec inscriptions?” I
+asked thoughtfully, as we walked sadly over the campus in the direction
+of the chemistry building. “Have they a sufficient value, even on
+appreciative Fifth Avenue, to warrant murder?”
+
+“Well,” he remarked, “it does seem incomprehensible. Yet people do just
+such things. The psychologists tell us that there is a veritable mania
+for possessing such curios. However, it is possible that there may be
+some deeper significance in this case,” he added, his face puckered in
+thought.
+
+Who was the mysterious Mexican woman, who the shaggy Russian? I asked
+myself. Clearly, at least, if she existed at all, she was one of the
+millions not of Spanish but of Indian descent in the country south of
+us. As I reasoned it out, it seemed to me as if she must have been an
+accomplice. She could not have got into Northrop’s room either before
+or after Doctor Bernardo left. Then, too, the toe-and shoe-prints were
+not hers. But, I figured, she certainly had a part in the plot.
+
+While I was engaged in the vain effort to unravel the tragic affair by
+pure reason, Kennedy was at work with practical science.
+
+He began by examining the little dark cylinder on the end of the reed.
+On a piece of the stuff, broken off, he poured a dark liquid from a
+brown-glass bottle. Then he placed it under a microscope.
+
+“Microscopically,” he said slowly, “it consists almost wholly of
+minute, clear granules which give a blue reaction with iodine. They are
+starch. Mixed with them are some larger starch granules, a few plant
+cells, fibrous matter, and other foreign particles. And then, there is
+the substance that gives that acrid, numbing taste.” He appeared to be
+vacantly studying the floor.
+
+“What do you think it is?” I asked, unable to restrain myself.
+
+“Aconite,” he answered slowly, “of which the active principle is the
+deadly poisonous alkaloid, aconitin.”
+
+He walked over and pulled down a well-thumbed standard work on
+toxicology, turned the pages, then began to read aloud:
+
+Pure aconitin is probably the most actively poisonous substance with
+which we are acquainted and, if administered hypodermically, the
+alkaloid is even more powerfully poisonous than when taken by the
+mouth.
+
+As in the case of most of the poisonous alkaloids, aconitin does not
+produce any decidedly characteristic post-mortem appearances. There is
+no way to distinguish it from other alkaloids, in fact, no reliable
+chemical test. The physiological effects before death are all that can
+be relied on.
+
+Owing to its exceeding toxic nature, the smallness of the dose required
+to produce death, and the lack of tests for recognition, aconitin
+possesses rather more interest in legal medicine than most other
+poisons.
+
+It is one of the few substances which, in the present state of
+toxicology, might be criminally administered and leave no positive
+evidence of the crime. If a small but fatal dose of the poison were to
+be given, especially if it were administered hypodermically, the
+chances of its detection in the body after death would be practically
+none.
+
+
+
+
+CHAPTER XI
+THE “PILLAR OF DEATH”
+
+
+I was looking at him fixedly as the diabolical nature of what must have
+happened sank into my mind. Here was a poison that defied detection. I
+could see by the look on Craig’s face that that problem, alone, was
+enough to absorb his attention. He seemed fully to realize that we had
+to deal with a criminal so clever that he might never be brought to
+justice.
+
+An idea flashed over me.
+
+“How about the letters?” I suggested.
+
+“Good, Walter!” he exclaimed.
+
+He untied the package which Mrs. Northrop had given him and glanced
+quickly over one after another of the letters.
+
+“Ah!” he exclaimed, fairly devouring one dated at Mitla. “Listen—it
+tells about Northrop’s work and goes on:
+
+“‘I have been much interested in a cavern, or _subterraneo_, here, in
+the shape of a cross, each arm of which extends for some twelve feet
+underground. In the center it is guarded by a block of stone popularly
+called “the Pillar of Death.” There is a superstition that whoever
+embraces it will die before the sun goes down.
+
+“‘From the _subterraneo_ is said to lead a long, underground passage
+across the court to another subterranean chamber which is full of
+Mixtec treasure. Treasure hunters have dug all around it, and it is
+said that two old Indians, only, know of the immense amount of buried
+gold and silver, but that they will not reveal it.’”
+
+I started up. Here was the missing link which I had been waiting for.
+
+“There, at least, is the motive,” I blurted out. “That is why Bernardo
+was so reticent. Northrop, in his innocence of heart, had showed him
+that inscription.”
+
+Kennedy said nothing as he finally tied up the little packet of letters
+and locked it in his safe. He was not given to hasty generalizations;
+neither was he one who clung doggedly to a preconceived theory.
+
+It was still early in the afternoon. Craig and I decided to drop into
+the museum again in order to see Doctor Bernardo. He was not there and
+we sat down to wait.
+
+Just then the letter box in the door clicked. It was the postman on his
+rounds. Kennedy walked over and picked up the letter.
+
+The postmark bore the words, “Mexico City,” and a date somewhat later
+than that on which Northrop had left Vera Cruz. In the lower corner,
+underscored, were the words, “Personal—Urgent.”
+
+“I’d like to know what is in that,” remarked Craig, turning it over and
+over.
+
+He appeared to be considering something, for he rose suddenly and
+shoved the letter into his pocket.
+
+I followed, and a few moments later, across the campus in his
+laboratory, he was working quickly over an X-ray apparatus. He had
+placed the letter in it.
+
+“These are what are known as ‘low’ tubes,” he explained. “They give out
+‘soft rays.’” He continued to work for a few moments, then handed me
+the letter.
+
+“Now, Walter,” he said, “if you will just hurry back to the museum and
+replace that letter, I think I will have something that will astonish
+you—though whether it will have any bearing on the case, remains to be
+seen.”
+
+“What is it?” I asked, a few minutes later, when I had rejoined him,
+after returning the letter. He was poring intently over what looked
+like a negative.
+
+“The possibility of reading the contents of documents inclosed in a
+sealed envelope,” he replied, still studying the shadowgraph closely,
+“has already been established by the well-known English scientist,
+Doctor Hall Edwards. He has been experimenting with the method of using
+X-rays recently discovered by a German scientist, by which radiographs
+of very thin substances, such as a sheet of paper, a leaf, an insect’s
+body, may be obtained. These thin substances through which the rays
+used formerly to pass without leaving an impression, can now be
+radiographed.”
+
+I looked carefully as he traced out something on the negative. On it
+was easily possible, following his guidance, to read the words
+inscribed on the sheet of paper inside. So admirably defined were all
+the details that even the gum on the envelope and the edges of the
+sheet of paper inside the envelope could be distinguished.
+
+“Any letter written with ink having a mineral basis can be
+radiographed,” added Craig. “Even when the sheet is folded in the usual
+way, it is possible by taking a radiograph stereoscopically, to
+distinguish the writing, every detail standing out in relief. Besides,
+it can be greatly magnified, which aids in deciphering it if it is
+indistinct or jumbled up. Some of it looks like mirror writing. Ah,” he
+added, “here’s something interesting!”
+
+Together we managed to trace out the contents of several paragraphs, of
+which the significant parts were as follows:
+
+I am expecting that my friend Señora Herreria will be in New York by
+the time you receive this, and should she call on you, I know you will
+accord her every courtesy. She has been in Mexico City for a few days,
+having just returned from Mitla, where she met Professor Northrop. It
+is rumored that Professor Northrop has succeeded in smuggling out of
+the country a very important stone bearing an inscription which, I
+understand, is of more than ordinary interest. I do not know anything
+definite about it, as Señora Herreria is very reticent on the matter,
+but depend on you to find out if possible and let me know of it.
+
+According to the rumors and the statements of the _señora_, it seems
+that Northrop has taken an unfair advantage of the situation down in
+Oaxaca, and I suppose she and others who know about the inscription
+feel that it is really the possession of the government.
+
+You will find that the _señora_ is an accomplished antiquarian and
+scholar. Like many others down here just now, she has a high regard for
+the Japanese. As you know, there exists a natural sympathy between some
+Mexicans and Japanese, owing to what is believed to be a common origin
+of the two races.
+
+In spite of the assertions of many to the contrary, there is little
+doubt left in the minds of students that the Indian races which have
+peopled Mexico were of Mongolian stock. Many words in some dialects are
+easily understood by Chinese immigrants. A secretary of the Japanese
+legation here was able recently to decipher old Mixtec inscriptions
+found in the ruins of Mitla.
+
+Señora Herreria has been much interested in establishing the
+relationship and, I understand, is acquainted with a Japanese curio
+dealer in New York who recently visited Mexico for the same purpose. I
+believe that she wishes to collaborate with him on a monograph on the
+subject, which is expected to have a powerful effect on the public
+opinion both here and at Tokyo.
+
+In regard to the inscription which Northrop has taken with him, I rely
+on you to keep me informed. There seems to be a great deal of mystery
+connected with it, and I am simply hazarding a guess as to its nature.
+If it should prove to be something which might interest either the
+Japanese or ourselves, you can see how important it may be, especially
+in view of the forthcoming mission of General Francisco to Tokyo.
+
+Very sincerely yours,
+DR. EMILIO SANCHEZ, Director.
+
+
+“Bernardo is a Mexican,” I exclaimed, as Kennedy finished reading, “and
+there can be no doubt that the woman he mentioned was this Señora
+Herreria.”
+
+Kennedy said nothing, but seemed to be weighing the various paragraphs
+in the letter.
+
+“Still,” I observed, “so far, the only one against whom we have any
+direct suspicion in the case is the shaggy Russian, whoever he is.”
+
+“A man whom Bernardo says looked like a Russian,” corrected Craig.
+
+He was pacing the laboratory restlessly.
+
+“This is becoming quite an international affair,” he remarked finally,
+pausing before me, his hat on. “Would you like to relax your mind by a
+little excursion among the curio shops of the city? I know something
+about Japanese curios—more, perhaps, than I do of Mexican. It may amuse
+us, even if it doesn’t help in solving the mystery. Meanwhile, I shall
+make arrangements for shadowing Bernardo. I want to know just how he
+acts after he reads that letter.”
+
+He paused long enough to telephone his instructions to an uptown
+detective agency which could be depended on for such mere routine work,
+then joined me with the significant remark: “Blood is thicker than
+water, anyhow, Walter. Still, even if the Mexicans are influenced by
+sentiment, I hardly think that would account for the interest of our
+friends from across the water in the matter.”
+
+I do not know how many of the large and small curio shops of the city
+we visited that afternoon. At another time, I should have enjoyed the
+visits immensely, for anyone seeking articles of beauty will find the
+antique shops of Fifth and Fourth Avenues and the side streets well
+worth visiting.
+
+We came, at length, to one, a small, quaint, dusty rookery, down in a
+basement, entered almost directly from the street. It bore over the
+door a little gilt sign which read simply, “Sato’s.”
+
+As we entered, I could not help being impressed by the wealth of
+articles in beautiful cloisonne enamel, in mother-of-pearl, lacquer,
+and champleve. There were beautiful little koros, or incense burners,
+vases, and teapots. There were enamels incrusted, translucent, and
+painted, works of the famous Namikawa, of Kyoto, and Namikawa, of
+Tokyo. Satsuma vases, splendid and rare examples of the potter’s art,
+crowded gorgeously embroidered screens depicting all sorts of brilliant
+scenes, among others the sacred Fujiyama rising in the stately
+distance. Sato himself greeted us with a ready smile and bow.
+
+“I am just looking for a few things to add to my den,” explained
+Kennedy, adding, “nothing in particular, but merely whatever happens to
+strike my fancy.”
+
+“Surely, then, you have come to the right shop,” greeted Sato. “If
+there is anything that interests you, I shall be glad to show it.”
+
+“Thank you,” replied Craig. “Don’t let me trouble you with your other
+customers. I will call on you if I see anything.”
+
+For several minutes, Craig and I busied ourselves looking about, and we
+did not have to feign interest, either.
+
+“Often things are not as represented,” he whispered to me, after a
+while, “but a connoiseur can tell spurious goods. These are the real
+thing, mostly.”
+
+“Not one in fifty can tell the difference,” put in the voice of Sato,
+at his elbow.
+
+“Well, you see I happen to know,” Craig replied, not the least
+disconcerted. “You can’t always be too sure.”
+
+A laugh and a shrug was Sato’s answer. “It’s well all are not so keen,”
+he said, with a frank acknowledgment that he was not above sharp
+practices.
+
+I glanced now and then at the expressionless face of the curio dealer.
+Was it merely the natural blankness of his countenance that impressed
+me, or was there, in fact, something deep and dark hidden in it,
+something of “East is East and West is West” which I did not and could
+not understand? Craig was admiring the bronzes. He had paused before
+one, a square metal fire-screen of odd design, with the title on a
+card, “Japan Gazing at the World.”
+
+It represented Japan as an eagle, with beak and talons of burnished
+gold, resting on a rocky island about which great waves dashed. The
+bird had an air of dignity and conscious pride in its strength, as it
+looked out at the world, a globe revolving in space.
+
+“Do you suppose there is anything significant in that?” I asked,
+pointing to the continent of North America, also in gold and
+prominently in view.
+
+“Ah, honorable sir,” answered Sato, before Kennedy could reply, “the
+artist intended by that to indicate Japan’s friendliness for America
+and America’s greatness.”
+
+He was inscrutable. It seemed as if he were watching our every move,
+and yet it was done with a polite cordiality that could not give
+offense.
+
+Behind some bronzes of the Japanese Hercules destroying the demons and
+other mythical heroes was a large alcove, or _tokonoma_, decorated with
+peacock, stork, and crane panels. Carvings and lacquer added to the
+beauty of it. A miniature chrysanthemum garden heightened the illusion.
+Carved _hinoki_ wood framed the panels, and the roof was supported by
+columns in the old Japanese style, the whole being a compromise between
+the very simple and quiet and the polychromatic. The dark woods, the
+lanterns, the floor tiles of dark red, and the cushions of rich gold
+and yellow were most alluring. It had the genuine fascination of the
+Orient.
+
+“Will the gentlemen drink a little _sake?_” Sato asked politely.
+
+Craig thanked him and said that we would.
+
+“Otaka!” Sato called.
+
+A peculiar, almost white-skinned attendant answered, and a moment later
+produced four cups and poured out the rice brandy, taking his own
+quietly, apart from us. I watched him drink, curiously. He took the
+cup; then, with a long piece of carved wood, he dipped into the _sake_,
+shaking a few drops on the floor to the four quarters. Finally, with a
+deft sweep, he lifted his heavy mustache with the piece of wood and
+drank off the draft almost without taking breath.
+
+He was a peculiar man of middle height, with a shock of dark, tough,
+woolly hair, well formed and not bad-looking, with a robust general
+physique, as if his ancestors had been meat eaters. His forehead was
+narrow and sloped backward; the cheekbones were prominent; nose hooked,
+broad and wide, with strong nostrils; mouth large, with thick lips, and
+not very prominent chin. His eyes were perhaps the most noticeable
+feature. They were dark gray, almost like those of a European.
+
+As Otaka withdrew with the empty cups, we rose to continue our
+inspection of the wonders of the shop. There were ivories of all
+descriptions. Here was a two-handled sword, with a very large ivory
+handle, a weirdly carved scabbard, and wonderful steel blade. By the
+expression of Craig’s face, Sato knew that he had made a sale.
+
+Craig had been rummaging among some warlike instruments which Sato,
+with the instincts of a true salesman, was now displaying, and had
+picked up a bow. It was short, very strong, and made of pine wood. He
+held it horizontally and twanged the string. I looked up in time to
+catch a pleased expression on the face of Otaka.
+
+“Most people would have held it the other way,” commented Sato.
+
+Craig said nothing, but was examining an arrow, almost twenty inches
+long and thick, made of cane, with a point of metal very sharp but
+badly fastened. He fingered the deep blood groove in the scooplike head
+of the arrow and looked at it carefully.
+
+“I’ll take that,” he said, “only I wish it were one with the regular
+reddish-brown lump in it.”
+
+“Oh, but, honorable sir,” apologized Sato, “the Japanese law prohibits
+that, now. There are few of those, and they are very valuable.”
+
+“I suppose so,” agreed Craig. “This will do, though. You have a
+wonderful shop here, Sato. Some time, when I feel richer, I mean to
+come in again. No, thank you, you need not send them; I’ll carry them.”
+
+We bowed ourselves out, promising to come again when Sato received a
+new consignment from the Orient which he was expecting.
+
+“That other Jap is a peculiar fellow,” I observed, as we walked along
+uptown again.
+
+“He isn’t a Jap,” remarked Craig. “He is an Ainu, one of the aborigines
+who have been driven northward into the island of Yezo.”
+
+“An Ainu?” I repeated.
+
+“Yes. Generally thought, now, to be a white race and nearer of kin to
+Europeans than Asiatics. The Japanese have pushed them northward and
+are now trying to civilize them. They are a dirty, hairy race, but when
+they are brought under civilizing influences they adapt themselves to
+their environment and make very good servants. Still, they are on about
+the lowest scale of humanity.”
+
+“I thought Otaka was very mild,” I commented.
+
+“They are a most inoffensive and peaceable people usually,” he
+answered, “good-natured and amenable to authority. But they become
+dangerous when driven to despair by cruel treatment. The Japanese
+government is very considerate of them—but not all Japanese are.”
+
+
+
+
+CHAPTER XII
+THE ARROW POISON
+
+
+Far into the night Craig was engaged in some very delicate and minute
+microscopic work in the laboratory.
+
+We were about to leave when there was a gentle tap on the door. Kennedy
+opened it and admitted a young man, the operative of the detective
+agency who had been shadowing Bernardo. His report was very brief, but,
+to me at least, significant. Bernardo, on his return to the museum, had
+evidently read the letter, which had agitated him very much, for a few
+moments later he hurriedly left and went downtown to the Prince Henry
+Hotel. The operative had casually edged up to the desk and overheard
+whom he asked for. It was Señora Herreria. Once again, later in the
+evening, he had asked for her, but she was still out.
+
+It was quite early the next morning, when Kennedy had resumed his
+careful microscopic work, that the telephone bell rang, and he answered
+it mechanically. But a moment later a look of intense surprise crossed
+his face.
+
+“It was from Doctor Leslie,” he announced, hanging up the receiver
+quickly. “He has a most peculiar case which he wants me to see—a
+woman.”
+
+Kennedy called a cab, and, at a furious pace, we dashed across the city
+and down to the Metropolitan Hospital, where Doctor Leslie was waiting.
+He met us eagerly and conducted us to a little room where, lying
+motionless on a bed, was a woman.
+
+She was a striking-looking woman, dark of hair and skin, and in life
+she must have been sensuously attractive. But now her face was drawn
+and contorted—with the same ghastly look that had been on the face of
+Northrop.
+
+“She died in a cab,” explained Doctor Leslie, “before they could get
+her to the hospital. At first they suspected the cab driver. But he
+seems to have proved his innocence. He picked her up last night on
+Fifth Avenue, reeling—thought she was intoxicated. And, in fact, he
+seems to have been right. Our tests have shown a great deal of alcohol
+present, but nothing like enough to have had such a serious effect.”
+
+“She told nothing of herself?” asked Kennedy.
+
+“No; she was pretty far gone when the cabby answered her signal. All he
+could get out of her was a word that sounded like ‘Curio-curio.’ He
+says she seemed to complain of something about her mouth and head. Her
+face was drawn and shrunken; her hands were cold and clammy, and then
+convulsions came on. He called an ambulance, but she was past saving
+when it arrived. The numbness seemed to have extended over all her
+body; swallowing was impossible; there was entire loss of her voice as
+well as sight, and death took place by syncope.”
+
+“Have you any clue to the cause of her death?” asked Craig.
+
+“Well, it might have been some trouble with her heart, I suppose,”
+remarked Doctor Leslie tentatively.
+
+“Oh, she looks strong that way. No, hardly anything organic.”
+
+“Well, then I thought she looked like a Mexican,” went on Doctor
+Leslie. “It might be some new tropical disease. I confess I don’t know.
+The fact is,” he added, lowering his voice, “I had my own theory about
+it until a few moments ago. That was why I called you.”
+
+“What do you mean?” asked Craig, evidently bent on testing his own
+theory by the other’s ignorance.
+
+Doctor Leslie made no answer immediately, but raised the sheet which
+covered her body and disclosed, in the fleshy part of the upper arm, a
+curious little red swollen mark with a couple of drops of darkened
+blood.
+
+“I thought at first,” he added, “that we had at last a genuine
+‘poisoned needle’ case. You see, that looked like it. But I have made
+all the tests for curare and strychnin without results.”
+
+At the mere suggestion, a procession of hypodermic-needle and
+white-slavery stories flashed before me.
+
+“But,” objected Kennedy, “clearly this was not a case of kidnaping. It
+is a case of murder. Have you tested for the ordinary poisons?”
+
+Doctor Leslie shook his head. “There was no poison,” he said,
+“absolutely none that any of our tests could discover.”
+
+Kennedy bent over and squeezed out a few drops of liquid from the wound
+on a microscope slide, and covered them.
+
+“You have not identified her yet,” he added, looking up. “I think you
+will find, Leslie, that there is a Señora Herreria registered at the
+Prince Henry who is missing, and that this woman will agree with the
+description of her. Anyhow, I wish you would look it up and let me
+know.”
+
+Half an hour later, Kennedy was preparing to continue his studies with
+the microscope when Doctor Bernardo entered. He seemed most solicitous
+to know what progress was being made on the case, and, although Kennedy
+did not tell much, still he did not discourage conversation on the
+subject.
+
+When we came in the night before, Craig had unwrapped and tossed down
+the Japanese sword and the Ainu bow and arrow on a table, and it was
+not long before they attracted Bernardo’s attention.
+
+“I see you are a collector yourself,” he ventured, picking them up.
+
+“Yes,” answered Craig, offhand; “I picked them up yesterday at Sato’s.
+You know the place?”
+
+“Oh, yes, I know Sato,” answered the curator, seemingly without the
+slightest hesitation. “He has been in Mexico—is quite a student.”
+
+“And the other man, Otaka?”
+
+“Other man—Otaka? You mean his wife?”
+
+I saw Kennedy check a motion of surprise and came to the rescue with
+the natural question: “His wife—with a beard and mustache?”
+
+It was Bernardo’s turn to be surprised. He looked at me a moment, then
+saw that I meant it, and suddenly his face lighted up.
+
+“Oh,” he exclaimed, “that must have been on account of the immigration
+laws or something of the sort. Otaka is his wife. The Ainus are much
+sought after by the Japanese as wives. The women, you know, have a
+custom of tattooing mustaches on themselves. It is hideous, but they
+think it is beautiful.”
+
+“I know,” I pursued, watching Kennedy’s interest in our conversation,
+“but this was not tattooed.”
+
+“Well, then, it must have been false,” insisted Bernardo.
+
+The curator chatted a few moments, during which I expected Kennedy to
+lead the conversation around to Señora Herreria. But he did not,
+evidently fearing to show his hand.
+
+“What did you make of it?” I asked, when he had gone. “Is he trying to
+hide something?”
+
+“I think he has simplified the case,” remarked Craig, leaning back, his
+hands behind his head, gazing up at the ceiling. “Hello, here’s Leslie!
+What did you find, Doctor?” The coroner had entered with a look of awe
+on his face, as if Kennedy had directed him by some sort of necromancy.
+
+“It was Señora Herreria!” he exclaimed. “She has been missing from the
+hotel ever since late yesterday afternoon. What do you think of it?”
+
+“I think,” replied Kennedy, speaking slowly and deliberately, “that it
+is very much like the Northrop case. You haven’t taken that up yet?”
+
+“Only superficially. What do you make of it?” asked the coroner.
+
+“I had an idea that it might be aconitin poisoning,” he said.
+
+Leslie glanced at him keenly for a moment. “Then you’ll never prove
+anything in the laboratory,” he said.
+
+“There are more ways of catching a criminal, Leslie,” put in Craig,
+“than are set down in the medico-legal text-books. I shall depend on
+you and Jameson to gather together a rather cosmopolitan crowd here
+to-night.”
+
+He said it with a quiet confidence which I could not gainsay, although
+I did not understand. However, mostly with the official aid of Doctor
+Leslie, I followed out his instructions, and it was indeed a strange
+party that assembled that night. There were Doctor Bernardo; Sato, the
+curio dealer; Otaka, the Ainu, and ourselves. Mrs. Northrop, of course,
+could not come.
+
+“Mexico,” began Craig, after he had said a few words explaining why he
+had brought us together, “is full of historical treasure. To all
+intents and purposes, the government says, ‘Come and dig.’ But when
+there are finds, then the government swoops down on them for its own
+national museum. The finder scarcely gets a chance to export them.
+However, now seemed to be the time to Professor Northrop to smuggle his
+finds out of the country.
+
+“But evidently it could not be done without exciting all kinds of
+rumors and suspicions. Stories seem to have spread far and fast about
+what he had discovered. He realized the unsettled condition of the
+country—perhaps wanted to confirm his reading of a certain inscription
+by consultation with one scholar whom he thought he could trust. At any
+rate, he came home.”
+
+Kennedy paused, making use of the silence for emphasis. “You have all
+read of the wealth that Cortez found in Mexico. Where are the gold and
+silver of the _conquistadores?_ Gone to the melting pot, centuries ago.
+But is there none left? The Indians believe so. There are persons who
+would stop at nothing—even at murder of American professors, murder of
+their own comrades, to get at the secret.”
+
+He laid his hand almost lovingly on his powerful little microscope as
+he resumed on another line of evidence.
+
+“And while we are on the subject of murders, two very similar deaths
+have occurred,” he went on. “It is of no use to try to gloss them over.
+Frankly, I suspected that they might have been caused by aconite
+poisoning. But, in the case of such poisoning, not only is the lethal
+dose very small but our chemical methods of detection are _nil_. The
+dose of the active principle, aconitin nitrate, is about one
+six-hundredth of a grain. There are no color tests, no reactions, as in
+the case of the other organic poisons.”
+
+I wondered what he was driving at. Was there, indeed, no test? Had the
+murderer used the safest of poisons—one that left no clue? I looked
+covertly at Sato’s face. It was impassive. Doctor Bernardo was visibly
+uneasy as Kennedy proceeded. Cool enough up to the time of the mention
+of the treasure, I fancied, now, that he was growing more and more
+nervous.
+
+Craig laid down on the table the reed stick with the little darkened
+cylinder on the end.
+
+“That,” he said, “is a little article which I picked up beneath
+Northrop’s window yesterday. It is a piece of _anno-noki_, or _bushi_.”
+I fancied I saw just a glint of satisfaction in Otaka’s eyes.
+
+“Like many barbarians,” continued Craig, “the Ainus from time
+immemorial have prepared virulent poisons with which they charged their
+weapons of the chase and warfare. The formulas for the preparations, as
+in the case of other arrow poisons of other tribes, are known only to
+certain members, and the secret is passed down from generation to
+generation as an heirloom, as it were. But in this case it is no longer
+a secret. It has now been proved that the active principle of this
+poison is aconite.”
+
+“If that is the case,” broke in Doctor Leslie, “it is hopeless to
+connect anyone directly in that way with these murders. There is no
+test for aconitin.”
+
+I thought Sato’s face was more composed and impassive than ever. Doctor
+Bernardo, however, was plainly excited.
+
+“What—no test—_none?_” asked Kennedy, leaning forward eagerly. Then, as
+if he could restrain the answer to his own question no longer, he shot
+out: “How about the new starch test just discovered by Professor
+Reichert, of the University of Pennsylvania? Doubtless you never
+dreamed that starch may be a means of detecting the nature of a poison
+in obscure cases in criminology, especially in cases where the quantity
+of poison necessary to cause death is so minute that no trace of it can
+be found in the blood.
+
+“The starch method is a new and extremely inviting subject to me. The
+peculiarities of the starch of any plant are quite as distinctive of
+the plant as are those of the hemoglobin crystals in the blood of an
+animal. I have analyzed the evidence of my microscope in this case
+thoroughly. When the arrow poison is introduced subcutaneously—say, by
+a person shooting a poisoned dart, which he afterward removes in order
+to destroy the evidence—the lethal constituents are rapidly absorbed.
+
+“But the starch remains in the wound. It can be recovered and studied
+microscopically and can be definitely recognized. Doctor Reichert has
+published a study of twelve hundred such starches from all sorts of
+plants. In this case, it not only proves to be aconitin but the starch
+granules themselves can be recognized. They came from this piece of
+arrow poison.”
+
+Every eye was fixed on him now.
+
+“Besides,” he rapped out, “in the soft soil beneath the window of
+Professor Northrop’s room, I found footprints. I have only to compare
+the impressions I took there and those of the people in this room, to
+prove that, while the real murderer stood guard below the window, he
+sent some one more nimble up the rain pipe to shoot the poisoned dart
+at Professor Northrop, and, later, to let down a rope by which he, the
+instigator, could gain the room, remove the dart, and obtain the key to
+the treasure he sought.”
+
+Kennedy was looking straight at Professor Bernardo.
+
+“A friend of mine in Mexico has written me about an inscription,” he
+burst out. “I received the letter only to-day. As nearly as I can
+gather, there was an impression that some of Northrop’s stuff would be
+valuable in proving the alleged kinship between Mexico and Japan,
+perhaps to arouse hatred of the United States.”
+
+“Yes—that is all very well,” insisted Kennedy. “But how about the
+treasure?”
+
+“Treasure?” repeated Bernardo, looking from one of us to another.
+
+“Yes,” pursued Craig relentlessly, “the treasure. You are an expert in
+reading the hieroglyphics. By your own statement, you and Northrop had
+been going over the stuff he had sent up. You know it.”
+
+Bernardo gave a quick glance from Kennedy to me. Evidently he saw that
+the secret was out.
+
+“Yes,” he said huskily, in a low tone, “Northrop and I were to follow
+the directions after we had plotted them out and were to share it
+together on the next expedition, which I could direct as a Mexican
+without so much suspicion. I should still have shared it with his widow
+if this unfortunate affair had not exposed the secret.”
+
+Bernardo had risen earnestly.
+
+“Kennedy,” he cried, “before God, if you will get back that stone and
+keep the secret from going further than this room, I will prove what I
+have said by dividing the Mixtec treasure with Mrs. Northrop and making
+her one of the richest widows in the country!”
+
+“That is what I wanted to be sure of,” nodded Craig. “Bernardo, Señora
+Herreria, of whom your friend wrote to you from Mexico, has been
+murdered in the same way that Professor Northrop was. Otaka was sent by
+her husband to murder Northrop, in order that they might obtain the
+so-called ‘Pillar of Death’ and the key to the treasure. Then, when the
+_señora_ was no doubt under the influence of _sake_ in the pretty
+little Oriental bower at the curio shop, a quick jab, and Otaka had
+removed one who shared the secret with them.”
+
+He had turned and faced the pair.
+
+“Sato,” he added, “you played on the patriotism of the _señora_ until
+you wormed from her the treasure secret. Evidently rumors of it had
+spread from Mexican Indians to Japanese visitors. And then, Otaka, all
+jealousy over one whom she, no doubt, justly considered a rival,
+completed your work by sending her forth to die, unknown, on the
+street. Walter, ring up First Deputy O’Connor. The stone is hidden
+somewhere in the curio shop. We can find it without Sato’s help. The
+quicker such a criminal is lodged safely in jail, the better for
+humanity.”
+
+Sato was on his feet, advancing cautiously toward Craig. I knew the
+dangers, now, of _anno-noki_, as well as the wonders of _jujutsu_, and,
+with a leap, I bounded past Bernardo and between Sato and Kennedy.
+
+How it happened, I don’t know, but, an instant later, I was sprawling.
+
+Before I could recover myself, before even Craig had a chance to pull
+the hair-trigger of his automatic, Sato had seized the Ainu arrow
+poison from the table, had bitten the little cylinder in half, and had
+crammed the other half into the mouth of Otaka.
+
+
+
+
+CHAPTER XIII
+THE RADIUM ROBBER
+
+
+Kennedy simply reached for the telephone and called an ambulance. But
+it was purely perfunctory. Dr. Leslie himself was the only official who
+could handle Sato’s case now.
+
+We had planned a little vacation for ourselves, but the planning came
+to naught. The next night we spent on a sleeper. That in itself is work
+to me.
+
+It all came about through a hurried message from Murray Denison,
+president of the Federal Radium Corporation. Nothing would do but that
+he should take both Kennedy and myself with him post-haste to
+Pittsburgh at the first news of what had immediately been called “the
+great radium robbery.”
+
+Of course the newspapers were full of it. The very novelty of an
+ultra-modern cracksman going off with something worth upward of a
+couple of hundred thousand dollars—and all contained in a few platinum
+tubes which could be tucked away in a vest pocket—had something about
+it powerfully appealing to the imagination.
+
+“Most ingenious, but, you see, the trouble with that safe is that it
+was built to keep radium _in_—not cracksmen _out_,” remarked Kennedy,
+when Denison had rushed us from the train to take a look at the little
+safe in the works of the Corporation.
+
+“Breaking into such a safe as this,” added Kennedy, after a cursory
+examination, “is simple enough, after all.”
+
+It was, however, a remarkably ingenious contrivance, about three feet
+in height and of a weight of perhaps a ton and a half, and all to house
+something weighing only a few grains.
+
+“But,” Denison hastened to explain, “we had to protect the radium not
+only against burglars, but, so to speak, against itself. Radium
+emanations pass through steel and experiments have shown that the best
+metal to contain them is lead. So, the difficulty was solved by making
+a steel outer case enclosing an inside leaden shell three inches
+thick.”
+
+Kennedy had been toying thoughtfully with the door.
+
+“Then the door, too, had to be contrived so as to prevent any escape of
+the emanations through joints. It is lathe turned and circular, a ‘dead
+fit.’ By means of a special contrivance any slight looseness caused by
+wear and tear of closing can be adjusted. And another feature. That is
+the appliance for preventing the loss of emanation when the door is
+opened. Two valves have been inserted into the door and before it is
+opened tubes with mercury are passed through which collect and store
+the emanation.”
+
+“All very nice for the radium,” remarked Craig cheerfully. “But the
+fellow had only to use an electric drill and the gram or more of radium
+was his.”
+
+“I know that—now,” ruefully persisted Denison. “But the safe was
+designed for us specially. The fellow got into it and got away, as far
+as I can see, without leaving a clue.”
+
+“Except one, of course,” interrupted Kennedy quickly.
+
+Denison looked at him a moment keenly, then nodded and said, “Yes—you
+are right. You mean one which he must bear on himself?”
+
+“Exactly. You can’t carry a gram or more of radium bromide long with
+impunity. The man to look for is one who in a few days will have
+somewhere on his body a radium burn which will take months to heal. The
+very thing he stole is a veritable Frankenstein’s monster bent on the
+destruction of the thief himself!”
+
+Kennedy had meanwhile picked up one of the Corporation’s circulars
+lying on a desk. He ran his eye down the list of names.
+
+“So, Hartley Haughton, the broker, is one of your stockholders,” mused
+Kennedy.
+
+“Not only one but _the_ one,” replied Denison with obvious pride.
+
+Haughton was a young man who had come recently into his fortune, and,
+while no one believed it to be large, he had cut quite a figure in Wall
+Street.
+
+“You know, I suppose,” added Denison, “that he is engaged to Felicie
+Woods, the daughter of Mrs. Courtney Woods?”
+
+Kennedy did not, but said nothing.
+
+“A most delightful little girl,” continued Denison thoughtfully. “I
+have known Mrs. Woods for some time. She wanted to invest, but I told
+her frankly that this is, after all, a speculation. We may not be able
+to swing so big a proposition, but, if not, no one can say we have
+taken a dollar of money from widows and orphans.”
+
+“I should like to see the works,” nodded Kennedy approvingly.
+
+“By all means.”
+
+The plant was a row of long low buildings of brick on the outskirts of
+the city, once devoted to the making of vanadium steel. The ore, as
+Denison explained, was brought to Pittsburgh because he had found here
+already a factory which could readily be turned into a plant for the
+extraction of radium. Huge baths and vats and crucibles for the various
+acids and alkalis and other processes used in treating the ore stood at
+various points.
+
+“This must be like extracting gold from sea water,” remarked Kennedy
+jocosely, impressed by the size of the plant as compared to the
+product.
+
+“Except that after we get through we have something infinitely more
+precious than gold,” replied Denison, “something which warrants the
+trouble and outlay. Yes, the fact is that the percentage of radium in
+all such ores is even less than of gold in sea water.”
+
+“Everything seems to be most carefully guarded,” remarked Kennedy as we
+concluded our tour of the well-appointed works.
+
+He had gone over everything in silence, and now at last we had returned
+to the safe.
+
+“Yes,” he repeated slowly, as if confirming his original impression,
+“such an amount of radium as was stolen wouldn’t occasion immediate
+discomfort to the thief, I suppose, but later no infernal machine could
+be more dangerous to him.”
+
+I pictured to myself the series of fearful works of mischief and terror
+that might follow, a curse on the thief worse than that of the weirdest
+curses of the Orient, the danger to the innocent, and the fact that in
+the hands of a criminal it was an instrument for committing crimes that
+might defy detection.
+
+“There is nothing more to do here now,” he concluded. “I can see
+nothing for the present except to go back to New York. The telltale
+burn may not be the only clue, but if the thief is going to profit by
+his spoils we shall hear about it best in New York or by cable from
+London, Paris, or some other European city.”
+
+Our hurried departure from New York had not given us a chance to visit
+the offices of the Radium Corporation for the distribution of the salts
+themselves. They were in a little old office building on William
+Street, near the drug district and yet scarcely a moment’s walk from
+the financial district.
+
+“Our head bookkeeper, Miss Wallace, is ill,” remarked Denison when we
+arrived at the office, “but if there is anything I can do to help you,
+I shall be glad to do it. We depend on Miss Wallace a great deal.
+Haughton says she is the brains of the office.”
+
+Kennedy looked about the well-appointed suite curiously.
+
+“Is this another of those radium safes?” he asked, approaching one
+similar in appearance to that which had been broken open already.
+
+“Yes, only a little larger.”
+
+“How much is in it?”
+
+“Most of our supply. I should say about two and a half grams. Miss
+Wallace has the record.”
+
+“It is of the same construction, I presume,” pursued Kennedy. “I wonder
+whether the lead lining fits closely to the steel?”
+
+“I think not,” considered Denison. “As I remember there was a sort of
+insulating air cushion or something of the sort.”
+
+Denison was quite eager to show us about. In fact ever since he had
+hustled us out to view the scene of the robbery, his high nervous
+tension had given us scarcely a moment’s rest. For hours he had talked
+radium, until I felt that he, like his metal, must have an
+inexhaustible emanation of words. He was one of those nervous, active
+little men, a born salesman, whether of ribbons or radium.
+
+“We have just gone into furnishing radium water,” he went on, bustling
+about and patting a little glass tank.
+
+I looked closely and could see that the water glowed in the dark with a
+peculiar phosphorescence.
+
+“The apparatus for the treatment,” he continued, “consists of two glass
+and porcelain receptacles. Inside the larger receptacle is placed the
+smaller, which contains a tiny quantity of radium. Into the larger
+receptacle is poured about a gallon of filtered water. The emanation
+from that little speck of radium is powerful enough to penetrate its
+porcelain holder and charge the water with its curative properties.
+From a tap at the bottom of the tank the patient draws the number of
+glasses of water a day prescribed. For such purposes the emanation
+within a day or two of being collected is as good as radium itself.
+Why, this water is five thousand times as radioactive as the most
+radioactive natural spring water.”
+
+“You must have control of a comparatively large amount of the metal,”
+suggested Kennedy.
+
+“We are, I believe, the largest holders of radium in the world,” he
+answered. “I have estimated that all told there are not much more than
+ten grams, of which Madame Curie has perhaps three, while Sir Ernest
+Cassel of London is the holder of perhaps as much. We have nearly four
+grams, leaving about six or seven for the rest of the world.”
+
+Kennedy nodded and continued to look about.
+
+“The Radium Corporation,” went on Denison, “has several large deposits
+of radioactive ore in Utah in what is known as the Poor Little Rich
+Valley, a valley so named because from being about the barrenest and
+most unproductive mineral or agricultural hole in the hills, the sudden
+discovery of the radioactive deposits has made it almost priceless.”
+
+He had entered a private office and was looking over some mail that had
+been left on his desk during his absence.
+
+“Look at this,” he called, picking up a clipping from a newspaper which
+had been laid there for his attention. “You see, we have them aroused.”
+
+We read the clipping together hastily:
+
+PLAN TO CORNER WORLD’S RADIUM
+
+
+LONDON.—Plans are being matured to form a large corporation for the
+monopoly of the existing and future supply of radium throughout the
+world. The company is to be called Universal Radium, Limited, and the
+capital of ten million dollars will be offered for public subscription
+at par simultaneously in London, Paris and New York.
+
+The company’s business will be to acquire mines and deposits of
+radioactive substances as well as the control of patents and processes
+connected with the production of radium. The outspoken purpose of the
+new company is to obtain a world-wide monopoly and maintain the price.
+
+“Ah—a competitor,” commented Kennedy, handing back the clipping.
+
+“Yes. You know radium salts used always to come from Europe. Now we are
+getting ready to do some exporting ourselves. Say,” he added excitedly,
+“there’s an idea, possibly, in that.”
+
+“How?” queried Craig.
+
+“Why, since we should be the principal competitors to the foreign
+mines, couldn’t this robbery have been due to the machinations of these
+schemers? To my mind, the United States, because of its supply of
+radium-bearing ores, will have to be reckoned with first in cornering
+the market. This is the point, Kennedy. Would those people who seem to
+be trying to extend their new company all over the world stop at
+anything in order to cripple us at the start?”
+
+How much longer Denison would have rattled on in his effort to explain
+the robbery, I do not know. The telephone rang and a reporter from the
+_Record_, who had just read my own story in the _Star_, asked for an
+interview. I knew that it would be only a question of minutes now
+before the other men were wearing a path out on the stairs, and we
+managed to get away before the onrush began.
+
+“Walter,” said Kennedy, as soon as we had reached the street. “I want
+to get in touch with Halsey Haughton. How can it be done?”
+
+I could think of nothing better at that moment than to inquire at the
+_Star’s_ Wall Street office, which happened to be around the corner. I
+knew the men down there intimately, and a few minutes later we were
+whisked up in the elevator to the office.
+
+They were as glad to see me as I was to see them, for the story of the
+robbery had interested the financial district perhaps more than any
+other.
+
+“Where can I find Halsey Haughton at this hour?” I asked.
+
+“Say,” exclaimed one of the men, “what’s the matter? There have been
+all kinds of rumors in the Street about him to-day. Did you know he was
+ill?”
+
+“No,” I answered. “Where is he?”
+
+“Out at the home of his fiancee, who is the daughter of Mrs. Courtney
+Woods, at Glenclair.”
+
+“What’s the matter?” I persisted.
+
+“That’s just it. No one seems to know. They say—well—they say he has a
+cancer.”
+
+Halsey Haughton suffering from cancer? It was such an uncommon thing to
+hear of a young man that I looked up quickly in surprise. Then all at
+once it flashed over me that Denison and Kennedy had discussed the
+matter of burns from the stolen radium. Might not this be, instead of
+cancer, a radium burn?
+
+Kennedy, who had been standing a little apart from me while I was
+talking with the boys, signaled to me with a quick glance not to say
+too much, and a few minutes later we were on the street again.
+
+I knew without being told that he was bound by the next train to the
+pretty little New Jersey suburb of Glenclair.
+
+It was late when we arrived, yet Kennedy had no hesitation in calling
+at the quaint home of Mrs. Courtney Woods on Woodridge Avenue.
+
+Mrs. Woods, a well-set-up woman of middle age, who had retained her
+youth and good looks in a remarkable manner, met us in the foyer.
+Briefly, Kennedy explained that we had just come in from Pittsburgh
+with Mr. Denison and that it was very important that we should see
+Haughton at once.
+
+We had hardly told her the object of our visit when a young woman of
+perhaps twenty-two or three, a very pretty girl, with all the good
+looks of her mother and a freshness which only youth can possess,
+tiptoed quietly downstairs. Her face told plainly that she was deeply
+worried over the illness of her fiance.
+
+“Who is it, mother?” she whispered from the turn in the stairs. “Some
+gentlemen from the company? Hartley’s door was open when the bell rang,
+and he thought he heard something said about the Pittsburgh affair.”
+
+Though she had whispered, it had not been for the purpose of concealing
+anything from us, but rather that the keen ears of her patient might
+not catch the words. She cast an inquiring glance at us.
+
+“Yes,” responded Kennedy in answer to her look, modulating his tone.
+“We have just left Mr. Denison at the office. Might we see Mr. Haughton
+for a moment? I am sure that nothing we can say or do will be as bad
+for him as our going away, now that he knows that we are here.”
+
+The two women appeared to consult for a moment.
+
+“Felicie,” called a rather nervous voice from the second floor, “is it
+some one from the company?”
+
+“Just a moment, Hartley,” she answered, then, lower to her mother,
+added, “I don’t think it can do any harm, do you, mother?”
+
+“You remember the doctor’s orders, my dear.”
+
+Again the voice called her.
+
+“Hang the doctor’s orders,” the girl exclaimed, with an air of almost
+masculinity. “It can’t be half so bad as to have him worry. Will you
+promise not to stay long? We expect Dr. Bryant in a few moments,
+anyway.”
+
+
+
+
+CHAPTER XIV
+THE SPINTHARISCOPE
+
+
+We followed her upstairs and into Haughton’s room, where he was lying
+in bed, propped up by pillows. Haughton certainly was ill. There was no
+mistake about that. He was a tall, gaunt man with an air about him that
+showed that he found illness very irksome. Around his neck was a
+bandage, and some adhesive tape at the back showed that a plaster of
+some sort had been placed there.
+
+As we entered his eyes traveled restlessly from the face of the girl to
+our own in an inquiring manner. He stretched out a nervous hand to us,
+while Kennedy in a few short sentences explained how we had become
+associated with the case and what we had seen already.
+
+“And there is not a clue?” he repeated as Craig finished.
+
+“Nothing tangible yet,” reiterated Kennedy. “I suppose you have heard
+of this rumor from London of a trust that is going into the radium
+field internationally?”
+
+“Yes,” he answered, “that is the thing you read to me in the morning
+papers, you remember, Felicie. Denison and I have heard such rumors
+before. If it is a fight, then we shall give them a fight. They can’t
+hold us up, if Denison is right in thinking that they are at the bottom
+of this—this robbery.”
+
+“Then you think he may be right?” shot out Kennedy quickly.
+
+Haughton glanced nervously from Kennedy to me.
+
+“Really,” he answered, “you see how impossible it is for me to have an
+opinion? You and Denison have been over the ground. You know much more
+about it than I do. I am afraid I shall have to defer to you.”
+
+Again we heard the bell downstairs, and a moment later a cheery voice,
+as Mrs. Woods met some one down in the foyer, asked, “How is the
+patient to-night?”
+
+We could not catch the reply.
+
+“Dr. Bryant, my physician,” put in Haughton. “Don’t go. I will assume
+the responsibility for your being here. Hello, Doctor. Why, I’m much
+the same to-night, thank you. At least no worse since I took your
+advice and went to bed.”
+
+Dr. Bryant was a bluff, hearty man, with the personal magnetism which
+goes with the making of a successful physician. He had mounted the
+stairs quietly but rapidly, evidently prepared to see us.
+
+“Would you mind waiting in this little dressing room?” asked the
+doctor, motioning to another, smaller room adjoining.
+
+He had taken from his pocket a little instrument with a dial face like
+a watch, which he attached to Haughton’s wrist. “A pocket instrument to
+measure blood pressure,” whispered Craig, as we entered the little
+room.
+
+While the others were gathered about Haughton, we stood in the next
+room, out of earshot. Kennedy had leaned his elbow on a chiffonier. As
+he looked about the little room, more from force of habit than because
+he thought he might discover anything, Kennedy’s eye rested on a glass
+tray on the top in which lay some pins, a collar button or two, which
+Haughton had apparently just taken off, and several other little
+unimportant articles.
+
+Kennedy bent over to look at the glass tray more closely, a puzzled
+look crossed his face, and with a glance at the other room he gathered
+up the tray and its contents.
+
+“Keep up a good courage,” said Dr. Bryant. “You’ll come out all right,
+Haughton.” Then as he left the bedroom he added to us, “Gentlemen, I
+hope you will pardon me, but if you could postpone the remainder of
+your visit until a later day, I am sure you will find it more
+satisfactory.”
+
+There was an air of finality about the doctor, though nothing
+unpleasant in it. We followed him down the stairs, and as we did so,
+Felicie, who had been waiting in a reception room, appeared before the
+portieres, her earnest eyes fixed on his kindly face.
+
+“Dr. Bryant,” she appealed, “is he—is he, really—so badly?”
+
+The Doctor, who had apparently known her all her life, reached down and
+took one of her hands, patting it with his own in a fatherly way.
+“Don’t worry, little girl,” he encouraged. “We are going to come out
+all right—all right.”
+
+She turned from him to us and, with a bright forced smile which showed
+the stuff she was made of, bade us good night.
+
+Outside, the Doctor, apparently regretting that he had virtually forced
+us out, paused before his car. “Are you going down toward the station?
+Yes? I am going that far. I should be glad to drive you there.”
+
+Kennedy climbed into the front seat, leaving me in the rear where the
+wind wafted me their brief conversation as we sped down Woodbridge
+Avenue.
+
+“What seems to be the trouble?” asked Craig.
+
+“Very high blood pressure, for one thing,” replied the Doctor frankly.
+
+“For which the latest thing is the radium water cure, I suppose?”
+ventured Kennedy.
+
+“Well, radioactive water is one cure for hardening of the arteries. But
+I didn’t say he had hardening of the arteries. Still, he is taking the
+water, with good results. You are from the company?”
+
+Kennedy nodded.
+
+“It was the radium water that first interested him in it. Why, we found
+a pressure of 230 pounds, which is frightful, and we have brought it
+down to 150, not far from normal.”
+
+“Still that could have nothing to do with the sore on his neck,”
+hazarded Kennedy.
+
+The Doctor looked at him quickly, then ahead at the path of light which
+his motor shed on the road.
+
+He said nothing, but I fancied that even he felt there was something
+strange in his silence over the new complication. He did not give
+Kennedy a chance to ask whether there were any other such sores.
+
+“At any rate,” he said, as he throttled down his engine with a flourish
+before the pretty little Glenclair station, “that girl needn’t worry.”
+
+There was evidently no use in trying to extract anything further from
+him. He had said all that medical ethics or detective skill could get
+from him. We thanked him and turned to the ticket window to see how
+long we should have to wait.
+
+“Either that doctor doesn’t know what he is talking about or he is
+concealing something,” remarked Craig, as we paced up and down the
+platform. “I am inclined to read the enigma in the latter way.”
+
+Nothing more passed between us during the journey back, and we hurried
+directly to the laboratory, late as it was. Kennedy had evidently been
+revolving something over and over in his mind, for the moment he had
+switched on the light, he unlocked one of his air-and dust-proof
+cabinets and took from it an instrument which he placed on a table
+before him.
+
+It was a peculiar-looking instrument, like a round glass electric
+battery with a cylinder atop, smaller and sticking up like a safety
+valve. On that were an arm, a dial, and a lens fixed in such a way as
+to read the dial. I could not see what else the rather complicated
+little apparatus consisted of, but inside, when Kennedy brought near it
+the pole of a static electric machine two delicate thin leaves of gold
+seemed to fly wide apart when it was charged.
+
+Kennedy had brought the glass tray near the thing. Instantly the leaves
+collapsed and he made a reading through the lens.
+
+“What is it?” I asked.
+
+“A radioscope,” he replied, still observing the scale. “Really a very
+sensitive gold leaf electroscope, devised by one of the students of
+Madame Curie. This method of detection is far more sensitive even than
+the spectroscope.”
+
+“What does it mean when the leaves collapse?” I asked.
+
+“Radium has been near that tray,” he answered. “It is radioactive. I
+suspected it first when I saw that violet color. That is what radium
+does to that kind of glass. You see, if radium exists in a gram of
+inactive matter only to the extent of one in ten-thousand million parts
+its presence can be readily detected by this radioscope, and everything
+that has been rendered radioactive is the same. Ordinarily the air
+between the gold leaves is insulating. Bringing something radioactive
+near them renders the air a good conductor and the leaves fall under
+the radiation.”
+
+“Wonderful!” I exclaimed, marveling at the delicacy of it.
+
+“Take radium water,” he went on, “sufficiently impregnated with radium
+emanations to be luminous in the dark, like that water of Denison’s. It
+would do the same. In fact all mineral waters and the so-called
+curarive muds like fango are slightly radioactive. There seems to be a
+little radium everywhere on earth that experiments have been made, even
+in the interiors of buildings. It is ubiquitous. We are surrounded and
+permeated by radiations—that soil out there on the campus, the air of
+this room, all. But,” he added contemplatively, “there is something
+different about that tray. A lot of radium has been near that, and
+recently.”
+
+“How about that bandage about Haughton’s neck?” I asked suddenly. “Do
+you think radium could have had anything to do with that?” “Well, as to
+burns, there is no particular immediate effect usually, and sometimes
+even up to two weeks or more, unless the exposure has been long and to
+a considerable quantity. Of course radium keeps itself three or four
+degrees warmer than other things about it constantly. But that isn’t
+what does the harm. It is continually emitting little corpuscles, which
+I’ll explain some other time, traveling all the way from twenty to one
+hundred and thirty thousand miles a second, and these corpuscles
+blister and corrode the flesh like quick-moving missiles bombarding it.
+The gravity of such lesions increases with the purity of the radium.
+For instance I have known an exposure of half an hour to a
+comparatively small quantity through a tube, a box and the clothes to
+produce a blister fifteen days later. Curie said he wouldn’t trust
+himself in a room with a kilogram of it. It would destroy his eyesight,
+burn off his skin and kill him eventually. Why, even after a slight
+exposure your clothes are radioactive—the electroscope will show that.”
+
+He was still fumbling with the glass plate and the various articles on
+it.
+
+“There’s something very peculiar about all this,” he muttered, almost
+to himself.
+
+Tired by the quick succession of events of the past two days, I left
+Kennedy still experimenting in his laboratory and retired, still
+wondering when the real clue was to develop. Who could it have been who
+bore the tell-tale burn? Was the mark hidden by the bandage about
+Haughton’s neck the brand of the stolen tubes? Or were there other
+marks on his body which we could not see?
+
+No answer came to me, and I fell asleep and woke up without a radiation
+of light on the subject. Kennedy spent the greater part of the day
+still at work at his laboratory, performing some very delicate
+experiments. Finding nothing to do there, I went down to the _Star_
+office and spent my time reading the reports that came in from the
+small army of reporters who had been assigned to run down clues in the
+case which was the sensation of the moment. I have always felt my own
+lips sealed in such cases, until the time came that the story was
+complete and Kennedy released me from any further need of silence. The
+weird and impossible stories which came in not only to the _Star_ but
+to the other papers surely did make passable copy in this instance, but
+with my knowledge of the case I could see that not one of them brought
+us a step nearer the truth.
+
+One thing which uniformly puzzled the newspapers was the illness of
+Haughton and his enforced idleness at a time which was of so much
+importance to the company which he had promoted and indeed very largely
+financed. Then, of course, there was the romantic side of his
+engagement to Felicie Woods.
+
+Just what connection Felicie Woods had with the radium robbery if any,
+I was myself unable quite to fathom. Still, that made no difference to
+the papers. She was pretty and therefore they published her picture,
+three columns deep, with Haughton and Denison, who were intimately
+concerned with the real loss in little ovals perhaps an inch across and
+two inches in the opposite dimension.
+
+The late afternoon news editions had gone to press, and I had given up
+in despair, determined to go up to the laboratory and sit around idly
+watching Kennedy with his mystifying experiments, in preference to
+waiting for him to summon me.
+
+I had scarcely arrived and settled myself to an impatient watch, when
+an automobile drove up furiously, and Denison himself, very excited,
+jumped out and dashed into the laboratory.
+
+[Illustration] Denison himself, very excited, jumped out and dashed
+into the laboratory.
+
+
+“What’s the matter?” asked Kennedy, looking up from a test tube which
+he had been examining, with an air for all the world expressive of “Why
+so hot, little man?”
+
+“I’ve had a threat,” ejaculated Denison.
+
+He laid on one of the laboratory tables a letter, without heading and
+without signature, written in a disguised hand, with an evident attempt
+to simulate the cramped script of a foreign penmanship.
+
+“I know who did the Pittsburgh job. The same party is out to ruin
+Federal Radium. Remember Pittsburgh and be prepared!
+
+
+“A STOCKHOLDER.”
+
+
+“Well?” demanded Kennedy, looking up.
+
+“That can have only one meaning,” asserted Denison.
+
+“What is that?” inquired Kennedy coolly, as if to confirm his own
+interpretation.
+
+“Why, another robbery—here in New York, of course.”
+
+“But who would do it?” I asked.
+
+“Who?” repeated Denison. “Some one representing that European combine,
+of course. That is only part of the Trust method—ruin of competitors
+whom they cannot absorb.”
+
+“Then you have refused to go into the combine? You know who is backing
+it?”
+
+“No—no,” admitted Denison reluctantly. “We have only signified our
+intent to go it alone, as often as anyone either with or without
+authority has offered to buy us out. No, I do not even know who the
+people are. They never act in the open. The only hints I have ever
+received were through perfectly reputable brokers acting for others.”
+
+“Does Haughton know of this note?” asked Kennedy.
+
+“Yes. As soon as I received it, I called him up.”
+
+“What did he say?”
+
+“He said to disregard it. But—you know what condition he is in. I don’t
+know what to do, whether to surround the office by a squad of
+detectives or remove the radium to a regular safety deposit vault, even
+at the loss of the emanation. Haughton has left it to me.”
+
+Suddenly the thought flashed across my mind that perhaps Haughton could
+act in this uninterested fashion because he had no fear of ruin either
+way. Might he not be playing a game with the combination in which he
+had protected himself so that he would win, no matter what happened?
+
+“What shall I do?” asked Denison. “It is getting late.”
+
+“Neither,” decided Kennedy.
+
+Denison shook his head. “No,” he said, “I shall have some one watch
+there, anyhow.”
+
+
+
+
+CHAPTER XV
+THE ASPHYXIATING SAFE
+
+
+Denison had scarcely gone to arrange for some one to watch the office
+that night, when Kennedy, having gathered up his radioscope and packed
+into a parcel a few other things from various cabinets, announced:
+“Walter, I must see that Miss Wallace, right away. Denison has already
+given me her address. Call a cab while I finish clearing up here. I
+don’t like the looks of this thing, even if Haughton does neglect it.”
+
+We found Miss Wallace at a modest boarding-house in an old but still
+respectable part of the city. She was a very pretty girl, of the
+slender type, rather a business woman than one given much to amusement.
+She had been ill and was still ill. That was evident from the
+solicitous way in which the motherly landlady scrutinized two strange
+callers.
+
+Kennedy presented a card from Denison, and she came down to the parlor
+to see us.
+
+“Miss Wallace,” began Kennedy, “I know it is almost cruel to trouble
+you when you are not feeling like office work, but since the robbery of
+the safe at Pittsburgh, there have been threats of a robbery of the New
+York office.”
+
+She started involuntarily, and it was evident, I thought, that she was
+in a very high-strung state.
+
+“Oh,” she cried, “why, the loss means ruin to Mr. Denison!”
+
+There were genuine tears in her eyes as she said it.
+
+“I thought you would be willing to aid us,” pursued Kennedy
+sympathetically. “Now, for one thing, I want to be perfectly sure just
+how much radium the Corporation owns, or rather owned before the first
+robbery.”
+
+“The books will show it,” she said simply.
+
+“They will?” commented Kennedy. “Then if you will explain to me briefly
+just the system you used in keeping account of it, perhaps I need not
+trouble you any more.”
+
+“I’ll go down there with you,” she answered bravely. “I’m better
+to-day, anyhow, I think.”
+
+She had risen, but it was evident that she was not as strong as she
+wanted us to think.
+
+“The least I can do is to make it as easy as possible by going in a
+car,” remarked Kennedy, following her into the hall where there was a
+telephone.
+
+The hallway was perfectly dark, yet as she preceded us I could see that
+the diamond pin which held her collar in the back sparkled as if a
+lighted candle had been brought near it. I had noticed in the parlor
+that she wore a handsome tortoiseshell comb set with what I thought
+were other brilliants, but when I looked I saw now that there was not
+the same sparkle to the comb which held her dark hair in a soft mass. I
+noticed these little things at the time, not because I thought they had
+any importance, but merely by chance, wondering at the sparkle of the
+one diamond which had caught my eye.
+
+“What do you make of her?” I asked as Kennedy finished telephoning.
+
+“A very charming and capable girl,” he answered noncommittally.
+
+“Did you notice how that diamond in her neck sparkled?” I asked
+quickly.
+
+He nodded. Evidently it had attracted his attention, too.
+
+“What makes it?” I pursued.
+
+“Well, you know radium rays will make a diamond fluoresce in the dark.”
+
+“Yes,” I objected, “but how about those in the comb?”
+
+“Paste, probably,” he answered tersely, as we heard her foot on the
+landing. “The rays won’t affect paste.”
+
+It was indeed a shame to take advantage of Miss Wallace’s loyalty to
+Denison, but she was so game about it that I knew only the utmost
+necessity on Kennedy’s part would have prompted him to do it. She had a
+key to the office so that it was not necessary to wait for Denison, if
+indeed we could have found him.
+
+Together she and Kennedy went over the records. It seemed that there
+were in the safe twenty-five platinum tubes of one hundred milligrams
+each, and that there had been twelve of the same amount at Pittsburgh.
+Little as it seemed in weight it represented a fabulous fortune.
+
+“You have not the combination?” inquired Kennedy.
+
+“No. Only Mr. Denison has that. What are you going to do to protect the
+safe to-night?” she asked.
+
+“Nothing especially,” evaded Kennedy.
+
+“Nothing?” she repeated in amazement.
+
+“I have another plan,” he said, watching her intently. “Miss Wallace,
+it was too much to ask you to come down here. You are ill.”
+
+She was indeed quite pale, as if the excitement had been an
+overexertion.
+
+“No, indeed,” she persisted. Then, feeling her own weakness, she moved
+toward the door of Denison’s office where there was a leather couch.
+“Let me rest here a moment. I do feel queer. I—”
+
+She would have fallen if he had not sprung forward and caught her as
+she sank to the floor, overcome by the exertion.
+
+Together we carried her in to the couch, and as we did so the comb from
+her hair clattered to the floor.
+
+Craig threw open the window, and bathed her face with water until there
+was a faint flutter of the eyelids.
+
+“Walter,” he said, as she began to revive, “I leave her to you. Keep
+her quiet for a few moments. She has unintentionally given me just the
+opportunity I want.”
+
+While she was yet hovering between consciousness and unconsciousness on
+the couch, he had unwrapped the package which he had brought with him.
+For a moment he held the comb which she had dropped near the
+radioscope. With a low exclamation of surprise he shoved it into his
+pocket.
+
+Then from the package he drew a heavy piece of apparatus which looked
+as if it might be the motor part of an electric fan, only in place of
+the fan he fitted a long, slim, vicious-looking steel bit. A flexible
+wire attached the thing to the electric light circuit and I knew that
+it was an electric drill. With his coat off he tugged at the little
+radium safe until he had moved it out, then dropped on his knees behind
+it and switched the current on in the electric drill.
+
+It was a tedious process to drill through the steel of the outer casing
+of the safe and it was getting late. I shut the door to the office so
+that Miss Wallace could not see.
+
+At last by the cessation of the low hum of the boring, I knew that he
+had struck the inner lead lining. Quietly I opened the door and stepped
+out. He was injecting something from an hermetically sealed lead tube
+into the opening he had made and allowing it to run between the two
+linings of lead and steel. Then using the tube itself he sealed the
+opening he had made and dabbed a little black over it.
+
+Quickly he shoved the safe back, then around it concealed several small
+coils with wires also concealed and leading out through a window to a
+court.
+
+“We’ll catch the fellow this time,” he remarked as he worked. “If you
+ever have any idea, Walter, of going into the burglary business, it
+would be well to ascertain if the safes have any of these little
+selenium cells as suggested by my friend, Mr. Hammer, the inventor. For
+by them an alarm can be given miles away the moment an intruder’s
+bull’s-eye falls on a hidden cell sensitive to light.”
+
+While I was delegated to take Miss Wallace home, Kennedy made
+arrangements with a small shopkeeper on the ground floor of a building
+that backed up on the court for the use of his back room that night,
+and had already set up a bell actuated by a system of relays which the
+weak current from the selenium cells could operate.
+
+It was not until nearly midnight that he was ready to leave the
+laboratory again, where he had been busily engaged in studying the
+tortoiseshell comb which Miss Wallace in her weakness had forgotten.
+
+The little shopkeeper let us in sleepily and Kennedy deposited a large
+round package on a chair in the back of the shop, as well as a long
+piece of rubber tubing. Nothing had happened so far.
+
+As we waited the shopkeeper, now wide awake and not at all unconvinced
+that we were bent on some criminal operation, hung around. Kennedy did
+not seem to care. He drew from his pocket a little shiny brass
+instrument in a lead case, which looked like an abbreviated microscope.
+
+“Look through it,” he said, handing it to me.
+
+I looked and could see thousands of minute sparks.
+
+“What is it?” I asked.
+
+“A spinthariscope. In that it is possible to watch the bombardment of
+the countless little corpuscles thrown off by radium, as they strike on
+the zinc blende crystal which forms the base. When radium was
+originally discovered, the interest was merely in its curious
+properties, its power to emit invisible rays which penetrated solid
+substances and rendered things fluorescent, of expending energy without
+apparent loss.
+
+“Then came the discovery,” he went on, “of its curative powers. But the
+first results were not convincing. Still, now that we know the reasons
+why radium may be dangerous and how to protect ourselves against them
+we know we possess one of the most wonderful of curative agencies.”
+
+I was thinking rather of the dangers than of the beneficence of radium
+just now, but Kennedy continued.
+
+“It has cured many malignant growths that seemed hopeless, brought back
+destroyed cells, exercised good effects in diseases of the liver and
+intestines and even the baffling diseases of the arteries. The reason
+why harm, at first, as well as good came, is now understood. Radium
+emits, as I told you before, three kinds of rays, the alpha, beta, and
+gamma rays, each with different properties. The emanation is another
+matter. It does not concern us in this case, as you will see.”
+
+Fascinated as I was by the mystery of the case, I began to see that he
+was gradually arriving at an explanation which had baffled everyone
+else.
+
+“Now, the alpha rays are the shortest,” he launched forth, “in length
+let us say one inch. They exert a very destructive effect on healthy
+tissue. That is the cause of injury. They are stopped by glass,
+aluminum and other metals, and are really particles charged with
+positive electricity. The beta rays come next, say, about an inch and a
+half. They stimulate cell growth. Therefore they are dangerous in
+cancer, though good in other ways. They can be stopped by lead, and are
+really particles charged with negative electricity. The gamma rays are
+the longest, perhaps three inches long, and it is these rays which
+effect cures, for they check the abnormal and stimulate the normal
+cells. They penetrate lead. Lead seems to filter them out from the
+other rays. And at three inches the other rays don’t reach, anyhow. The
+gamma rays are not charged with electricity at all, apparently.”
+
+He had brought a little magnet near the spinthariscope. I looked into
+it.
+
+“A magnet,” he explained, “shows the difference between the alpha,
+beta, and gamma rays. You see those weak and wobbly rays that seem to
+fall to one side? Those are the alpha rays. They have a strong action,
+though, on tissues and cells. Those falling in the other direction are
+the beta rays. The gamma rays seem to flow straight.”
+
+“Then it is the alpha rays with which we are concerned mostly now?” I
+queried, looking up.
+
+“Exactly. That is why, when radium is unprotected or insufficiently
+protected and comes too near, it is destructive of healthy cells,
+produces burns, sores, which are most difficult to heal. It is with the
+explanation of such sores that we must deal.”
+
+It was growing late. We had waited patiently now for some time. Kennedy
+had evidently reserved this explanation, knowing we should have to
+wait. Still nothing happened.
+
+Added to the mystery of the violet-colored glass plate was now that of
+the luminescent diamond. I was about to ask Kennedy point-blank what he
+thought of them, when suddenly the little bell before us began to buzz
+feebly under the influence of a current.
+
+I gave a start. The faithful little selenium cell burglar alarm had
+done the trick. I knew that selenium was a good conductor of
+electricity in the light, poor in the dark. Some one had, therefore,
+flashed a light on one of the cells in the Corporation office. It was
+the moment for which Kennedy had prepared.
+
+Seizing the round package and the tubing, he dashed out on the street
+and around the corner. He tried the door opening into the Radium
+Corporation hallway. It was closed, but unlocked. As it yielded and we
+stumbled in, up the old worn wooden stairs of the building, I knew that
+there must be some one there.
+
+A terrific, penetrating, almost stunning odor seemed to permeate the
+air even in the hall.
+
+Kennedy paused at the door of the office, tried it, found it unlocked,
+but did not open it.
+
+“That smell is ethyldichloracetate,” he explained. “That was what I
+injected into the air cushion of that safe between the two linings. I
+suppose my man here used an electric drill. He might have used thermit
+or an oxyacetylene blowpipe for all I would care. These fumes would
+discourage a cracksman from ‘soup’ to nuts,” he laughed, thoroughly
+pleased at the protection modern science had enabled him to devise.
+
+As we stood an instant by the door, I realized what had happened. We
+had captured our man. He was asphyxiated!
+
+Yet how were we to get to him? Would Craig leave him in there, perhaps
+to die? To go in ourselves meant to share his fate, whatever might be
+the effect of the drug.
+
+Kennedy had torn the wrapping off the package. From it he drew a huge
+globe with bulging windows of glass in the front and several curious
+arrangements on it at other points. To it he fitted the rubber tubing
+and a little pump. Then he placed the globe over his head, like a
+diver’s helmet, and fastened some air-tight rubber arrangement about
+his neck and shoulders.
+
+“Pump, Walter!” he shouted. “This is an oxygen helmet such as is used
+in entering mines filled with deadly gases.”
+
+Without another word he was gone into the blackness of the noxious
+stifle which filled the Radium Corporation office since the cracksman
+had struck the unexpected pocket of rapidly evaporating stuff.
+
+I pumped furiously.
+
+Inside I could hear him blundering around. What was he doing?
+
+He was coming back slowly. Was he, too, overcome?
+
+As he emerged into the darkness of the hallway where I myself was
+almost sickened, I saw that he was dragging with him a limp form.
+
+A rush of outside air from the street door seemed to clear things a
+little. Kennedy tore off the oxygen helmet and dropped down on his
+knees beside the figure, working its arms in the most approved manner
+of resuscitation.
+
+“I think we can do it without calling on the pulmotor,” he panted.
+“Walter, the fumes have cleared away enough now in the outside office.
+Open a window—and keep that street door open, too.”
+
+I did so, found the switch and turned on the lights.
+
+It was Denison himself!
+
+For many minutes Kennedy worked over him. I bent down, loosened his
+collar and shirt, and looked eagerly at his chest for the tell-tale
+marks of the radium which I felt sure must be there. There was not even
+a discoloration.
+
+Not a word was said, as Kennedy brought the stupefied little man
+around.
+
+Denison, pale, shaken, was leaning back now in a big office chair,
+gasping and holding his head.
+
+Kennedy, before him, reached down into his pocket and handed him the
+spinthariscope.
+
+“You see that?” he demanded.
+
+Denison looked through the eyepiece.
+
+“Wh—where did you get so much of it?” he asked, a queer look on his
+face.
+
+“I got that bit of radium from the base of the collar button of Hartley
+Haughton,” replied Kennedy quietly, “a collar button which some one
+intimate with him had substituted for his own, bringing that deadly
+radium with only the minutest protection of a thin strip of metal close
+to the back of his neck, near the spinal cord and the medulla oblongata
+which controls blood pressure. That collar button was worse than the
+poisoned rings of the Borgias. And there is more radium in the pretty
+gift of a tortoiseshell comb with its paste diamonds which Miss Wallace
+wore in her hair. Only a fraction of an inch, not enough to cut off the
+deadly alpha rays, protected the wearers of those articles.”
+
+He paused a moment, while surging through my mind came one after
+another the explanations of the hitherto inexplicable. Denison seemed
+almost to cringe in the chair, weak already from the fumes.
+
+“Besides,” went on Kennedy remorselessly, “when I went in there to drag
+you out, I saw the safe open. I looked. There was nothing in those
+pretty platinum tubes, as I suspected. European trust—bah! All the
+cheap devices of a faker with a confederate in London to send a
+cablegram—and another in New York to send a threatening letter.”
+
+Kennedy extended an accusing forefinger at the man cowering before him.
+
+“This is nothing but a get-rich-quick scheme, Denison. There never was
+a milligram of radium in the Poor Little Rich Valley, not a milligram
+here in all the carefully kept reports of Miss Wallace—except what was
+bought outside by the Corporation with the money it collected from its
+dupes. Haughton has been fleeced. Miss Wallace, blinded by her loyalty
+to you—you will always find such a faithful girl in such schemes as
+yours—has been fooled.
+
+“And how did you repay it? What was cleverer, you said to yourself,
+than to seem to be robbed of what you never had, to blame it on a
+bitter rival who never existed? Then to make assurance doubly sure, you
+planned to disable, perhaps get rid of the come-on whom you had
+trimmed, and the faithful girl whose eyes you had blinded to your
+gigantic swindle.
+
+“Denison,” concluded Kennedy, as the man drew back, his very face
+convicting him, “Denison, you are the radium robber—robber in another
+sense!”
+
+
+
+
+CHAPTER XVI
+THE DEAD LINE
+
+
+Maiden Lane, no less than Wall Street, was deeply interested in the
+radium case. In fact, it seemed that one case in this section of the
+city led to another.
+
+Naturally, the _Star_ and the other papers made much of the capture of
+Denison. Still, I was not prepared for the host of Maiden Lane cases
+that followed. Many of them were essentially trivial. But one proved to
+be of extreme importance.
+
+“Professor Kennedy, I have just heard of your radium case, and I—I feel
+that I can—trust you.”
+
+There was a note of appeal in the hesitating voice of the tall, heavily
+veiled woman whose card had been sent up to us with a nervous “Urgent”
+written across its face.
+
+It was very early in the morning, but our visitor was evidently
+completely unnerved by some news which she had just received and which
+had sent her posting to see Craig.
+
+Kennedy met her gaze directly with a look that arrested her involuntary
+effort to avoid it again. She must have read in his eyes more than in
+his words that she might trust him.
+
+“I—I have a confession to make,” she faltered.
+
+“Please sit down, Mrs. Moulton,” he said simply. “It is my business to
+receive confidences—and to keep them.”
+
+She sank into, rather than sat down in, the deep leather rocker beside
+his desk, and now for the first time raised her veil.
+
+Antoinette Moulton was indeed stunning, an exquisite creature with a
+wonderful charm of slender youth, brightness of eye and brunette
+radiance.
+
+I knew that she had been on the musical comedy stage and had had a
+rapid rise to a star part before her marriage to Lynn Moulton, the
+wealthy lawyer, almost twice her age. I knew also that she had given up
+the stage, apparently without a regret. Yet there was something strange
+about the air of secrecy of her visit. Was there a hint in it of a
+disagreement between the Moultons, I wondered, as I waited while
+Kennedy reassured her.
+
+Her distress was so unconcealed that Craig, for the moment, laid aside
+his ordinary inquisitorial manner. “Tell me just as much or just as
+little as you choose, Mrs. Moulton,” he added tactfully. “I will do my
+best.”
+
+A look almost of gratitude crossed her face.
+
+“When we were married,” she began again, “my husband gave me a
+beautiful diamond necklace. Oh, it must have been worth a hundred
+thousand dollars easily. It was splendid. Everyone has heard of it. You
+know, Lynn—er—Mr. Moulton, has always been an enthusiastic collector of
+jewels.”
+
+She paused again and Kennedy nodded reassuringly. I knew the thought in
+his mind. Moulton had collected one gem that was incomparable with all
+the hundred thousand dollar necklaces in existence.
+
+“Several months ago.” she went on rapidly, still avoiding his eyes and
+forcing the words from her reluctant lips, “I—oh, I needed
+money—terribly.”
+
+She had risen and faced him, pressing her daintily gloved hands
+together in a little tremble of emotion which was none the less genuine
+because she had studied the art of emotion.
+
+“I took the necklace to a jeweler, Herman Schloss, of Maiden Lane, a
+man with whom my husband had often had dealings and whom I thought I
+could trust. Under a promise of secrecy he loaned me fifty thousand
+dollars on it and had an exact replica in paste made by one of his best
+workmen. This morning, just now, Mr. Schloss telephoned me that his
+safe had been robbed last night. My necklace is gone!”
+
+She threw out her hands in a wildly appealing gesture.
+
+“And if Lynn finds that the necklace in our wall safe is of paste—as he
+will find, for he is an expert in diamonds—oh—what shall I do? Can’t
+you—can’t you find my necklace?”
+
+Kennedy was following her now eagerly. “You were blackmailed out of the
+money?” he queried casually, masking his question.
+
+There was a sudden, impulsive drooping of her mouth, an evasion and
+keen wariness in her eyes. “I can’t see that that has anything to do
+with the robbery,” she answered in a low voice.
+
+“I beg your pardon,” corrected Kennedy quickly. “Perhaps not. I’m
+sorry. Force of habit, I suppose. You don’t know anything more about
+the robbery?”
+
+“N—no, only that it seems impossible that it could have happened in a
+place that has the wonderful burglar alarm protection that Mr. Schloss
+described to me.”
+
+“You know him pretty well?”
+
+“Only through this transaction,” she replied hastily. “I wish to heaven
+I had never heard of him.”
+
+The telephone rang insistently.
+
+“Mrs. Moulton,” said Kennedy, as he returned the receiver to the hook,
+“it may interest you to know that the burglar alarm company has just
+called me up about the same case. If I had need of an added incentive,
+which I hope you will believe I have not, that might furnish it. I will
+do my best,” he repeated.
+
+“Thank you—a thousand times,” she cried fervently, and, had I been
+Craig, I think I should have needed no more thanks than the look she
+gave him as he accompanied her to the door of our apartment.
+
+It was still early and the eager crowds were pushing their way to
+business through the narrow network of downtown streets as Kennedy and
+I entered a large office on lower Broadway in the heart of the jewelry
+trade and financial district.
+
+“One of the most amazing robberies that has ever been attempted has
+been reported to us this morning,” announced James McLear, manager of
+the Hale Electric Protection, adding with a look half of anxiety, half
+of skepticism, “that is, if it is true.”
+
+McLear was a stocky man, of powerful build and voice and a general
+appearance of having been once well connected with the city detective
+force before an attractive offer had taken him into this position of
+great responsibility.
+
+“Herman Schloss, one of the best known of Maiden Lane jewelers,” he
+continued, “has been robbed of goods worth two or three hundred
+thousand dollars—and in spite of every modern protection. So that you
+will get it clearly, let me show you what we do here.”
+
+He ushered us into a large room, on the walls of which were hundreds of
+little indicators. From the front they looked like rows of little
+square compartments, tier on tier, about the size of ordinary post
+office boxes. Closer examination showed that each was equipped with a
+delicate needle arranged to oscillate backward and forward upon the
+very minutest interference with the electric current. Under the boxes,
+each of which bore a number, was a series of drops and buzzers numbered
+to correspond with the boxes.
+
+“In nearly every office in Maiden Lane where gems and valuable jewelry
+are stored,” explained McLear, “this electrical system of ours is
+installed. When the safes are closed at night and the doors swung
+together, a current of electricity is constantly shooting around the
+safes, conducted by cleverly concealed wires. These wires are picked up
+by a cable system which finds its way to this central office. Once
+here, the wires are safeguarded in such manner that foreign currents
+from other wires or from lightning cannot disturb the system.”
+
+We looked with intense interest at this huge electrical pulse that felt
+every change over so vast and rich an area.
+
+“Passing a big dividing board,” he went on, “they are distributed and
+connected each in its place to the delicate tangent galvanometers and
+sensitive indicators you see in this room. These instantly announce the
+most minute change in the working of the current, and each office has a
+distinct separate metallic circuit. Why, even a hole as small as a lead
+pencil in anything protected would sound the alarm here.”
+
+Kennedy nodded appreciatively.
+
+“You see,” continued McLear, glad to be able to talk to one who
+followed him so closely, “it is another evidence of science finding for
+us greater security in the use of a tiny electric wire than in massive
+walls of steel and intricate lock devices. But here is a case in which,
+it seems, every known protection has failed. We can’t afford to pass
+that by. If we have fallen down we want to know how, as well as to
+catch the burglar.”
+
+“How are the signals given?” I asked.
+
+“Well, when the day’s business is over, for instance, Schloss would
+swing the heavy safe doors together and over them place the doors of a
+wooden cabinet. That signals an alarm to us here. We answer it and if
+the proper signal is returned, all right. After that no one can tamper
+with the safe later in the night without sounding an alarm that would
+bring a quick investigation.”
+
+“But suppose that it became necessary to open the safe before the next
+morning. Might not some trusted employee return to the office, open it,
+give the proper signals and loot the safe?”
+
+“No indeed,” he answered confidently. “The very moment anyone touches
+the cabinet, the alarm is sounded. Even if the proper code signal is
+returned, it is not sufficient. A couple of our trusted men from the
+central office hustle around there anyhow and they don’t leave until
+they are satisfied that everything is right. We have the authorized
+signatures on hand of those who are supposed to open the safe and a
+duplicate of one of them must be given or there is an arrest.”
+
+McLear considered for a moment.
+
+“For instance, Schloss, like all the rest, was assigned a box in which
+was deposited a sealed envelope containing a key to the office and his
+own signature, in this case, since he alone knew the combination. Now,
+when an alarm is sounded, as it was last night, and the key removed to
+gain entrance to the office, a record is made and the key has to be
+sealed up again by Schloss. A report is also submitted showing when the
+signals are received and anything else that is worth recording. Last
+night our men found nothing wrong, apparently. But this morning we
+learn of the robbery.”
+
+“The point is, then,” ruminated Kennedy, “what happened in the interval
+between the ringing of the alarm and the arrival of the special
+officers? I think I’ll drop around and look Schloss’ place over,” he
+added quietly, evidently eager to begin at the actual scene of the
+crime.
+
+On the door of the office to which McLear took us was one of those
+small blue plates which chance visitors to Maiden Lane must have seen
+often. To the initiated—be he crook or jeweler—this simple sign means
+that the merchant is a member of the Jewelers’ Security Alliance,
+enough in itself, it would seem, to make the boldest burglar hesitate.
+For it is the motto of this organization to “get” the thief at any cost
+and at any time. Still, it had not deterred the burglar in this
+instance.
+
+“I know people are going to think it is a fake burglary,” exclaimed
+Schloss, a stout, prosperous-looking gem broker, as we introduced
+ourselves. “But over two hundred thousands dollars’ worth of stones are
+gone,” he half groaned. “Think of it, man,” he added, “one of the
+greatest robberies since the Dead Line was established. And if they can
+get away with it, why, no one down here is protected any more. Half a
+billion dollars in jewels in Maiden Lane and John Street are easy prey
+for the cracksmen!”
+
+Staggering though the loss must have been to him, he had apparently
+recovered from the first shock of the discovery and had begun the fight
+to get back what had been lost.
+
+It was, as McLear had intimated, a most amazing burglary, too. The door
+of Schloss’ safe was open when Kennedy and I arrived and found the
+excited jeweler nervously pacing the office. Surrounding the safe, I
+noticed a wooden framework constructed in such a way as to be a part of
+the decorative scheme of the office.
+
+Schloss banged the heavy doors shut.
+
+“There, that’s just how it was—shut as tight as a drum. There was
+absolutely no mark of anyone tampering with the combination lock. And
+yet the safe was looted!”
+
+“How did you discover it?” asked Craig. “I presume you carry burglary
+insurance?”
+
+Schloss looked up quickly. “That’s what I expected as a first question.
+No, I carried very little insurance. You see, I thought the safe, one
+of those new chrome steel affairs, was about impregnable. I never lost
+a moment’s sleep over it; didn’t think it possible for anyone to get
+into it. For, as you see, it is completely wired by the Hale Electric
+Protection—that wooden framework about it. No one could touch that when
+it was set without jangling a bell at the central office which would
+send men scurrying here to protect the place.”
+
+“But they must have got past it,” suggested Kennedy.
+
+“Yes—they must have. At least this morning I received the regular Hale
+report. It said that their wires registered last night as though some
+one was tampering with the safe. But by the time they got around, in
+less than five minutes, there was no one here, nothing seemed to be
+disturbed. So they set it down to induction or electrolysis, or
+something the matter with the wires. I got the report the first thing
+when I arrived here with my assistant, Muller.”
+
+Kennedy was on his knees, going over the safe with a fine brush and
+some powder, looking now and then through a small magnifying glass.
+
+“Not a finger print,” he muttered. “The cracksman must have worn
+gloves. But how did he get in? There isn’t a mark of ‘soup’ having been
+used to blow it up, nor of a ‘can-opener’ to rip it open, if that were
+possible, nor of an electric or any other kind of drill.”
+
+“I’ve read of those fellows who burn their way in,” said Schloss.
+
+“But there is no hole,” objected Kennedy, “not a trace of the use of
+thermit to burn the way in or of the oxyacetylene blowpipe to cut a
+piece out. Most extraordinary,” he murmured.
+
+“You see,” shrugged Schloss, “everyone will say it must have been
+opened by one who knew the combination. But I am the only one. I have
+never written it down or told anyone, not even Muller. You understand
+what I am up against?”
+
+“There’s the touch system,” I suggested. “You remember, Craig, the old
+fellow who used to file his finger tips to the quick until they were so
+sensitive that he could actually feel when he had turned the
+combination to the right plunger? Might not that explain the lack of
+finger prints also?” I added eagerly.
+
+“Nothing like that in this case, Walter,” objected Craig positively.
+“This fellow wore gloves, all right. No, this safe has been opened and
+looted by no ordinarily known method. It’s the most amazing case I ever
+saw in that respect—almost as if we had a cracksman in the fourth
+dimension to whom the inside of a closed cube is as accessible as is
+the inside of a plane square to us three dimensional creatures. It is
+almost incomprehensible.”
+
+I fancied I saw Schloss’ face brighten as Kennedy took this view. So
+far, evidently, he had run across only skepticism.
+
+“The stones were unset?” resumed Craig.
+
+“Mostly. Not all.”
+
+“You would recognize some of them if you saw them?”
+
+“Yes indeed. Some could be changed only by re-cutting. Even some of
+those that were set were of odd cut and size—some from a diamond
+necklace which belonged to a—”
+
+There was something peculiar in both his tone and manner as he cut
+short the words.
+
+“To whom?” asked Kennedy casually.
+
+“Oh, once to a well-known woman in society,” he said carefully. “It is
+mine, though, now—at least it was mine. I should prefer to mention no
+names. I will give a description of the stones.”
+
+“Mrs. Lynn Moulton, for instance?” suggested Craig quietly.
+
+Schloss jumped almost as if a burglar alarm had sounded under his very
+ears. “How did you know? Yes—but it was a secret. I made a large loan
+on it, and the time has expired.”
+
+“Why did she need money so badly?” asked Kennedy.
+
+“How should I know?” demanded Schloss.
+
+Here was a deepening mystery, not to be elucidated by continuing this
+line of inquiry with Schloss, it seemed.
+
+
+
+
+CHAPTER XVII
+THE PASTE REPLICA
+
+
+Carefully Craig was going over the office. Outside of the safe, there
+had apparently been nothing of value. The rest of the office was not
+even wired, and it seemed to have been Schloss’ idea that the few
+thousands of burglary insurance amply protected him against such loss.
+As for the safe, its own strength and the careful wiring might well
+have been considered quite sufficient under any hitherto to-be-foreseen
+circumstances.
+
+A glass door, around the bend of a partition, opened from the hallway
+into the office and had apparently been designed with the object of
+making visible the safe so that anyone passing might see whether an
+intruder was tampering with it.
+
+Kennedy had examined the door, perhaps in the expectation of finding
+finger prints there, and was passing on to other things, when a change
+in his position caused his eye to catch a large oval smudge on the
+glass, which was visible when the light struck it at the right angle.
+Quickly he dusted it over with the powder, and brought out the detail
+more clearly. As I examined it, while Craig made preparations to cut
+out the glass to preserve it, it seemed to contain a number of minute
+points and several more or less broken parallel lines. The edges
+gradually trailed off into an indistinct faintness.
+
+Business, naturally, was at a standstill, and as we were working near
+the door, we could see that the news of Schloss’ strange robbery had
+leaked out and was spreading rapidly. Scores of acquaintances in the
+trade stopped at the door to inquire about the rumor.
+
+To each, it seemed that Morris Muller, the working jeweler employed by
+Schloss, repeated the same story.
+
+“Oh,” he said, “it is a big loss—yes—but big as it is, it will not
+break Mr. Schloss. And,” he would add with the tradesman’s idea of
+humor, “I guess he has enough to play a game of poker—eh?”
+
+“Poker?” asked Kennedy smiling. “Is he much of a player?”
+
+“Yes. Nearly every night with his friends he plays.”
+
+Kennedy made a mental note of it. Evidently Schloss trusted Muller
+implicitly. He seemed like a partner, rather than an employee, even
+though he had not been entrusted with the secret combination.
+
+Outside, we ran into city detective Lieutenant Winters, the officer who
+was stationed at the Maiden Lane post, guarding that famous section of
+the Dead Line established by the immortal Byrnes at Fulton Street,
+below which no crook was supposed to dare even to be seen. Winters had
+been detailed on the case.
+
+“You have seen the safe in there?” asked Kennedy, as he was leaving to
+carry on his investigation elsewhere.
+
+Winters seemed to be quite as skeptical as Schloss had intimated the
+public would be. “Yes,” he replied, “there’s been an epidemic of
+robbery with the dull times—people who want to collect their burglary
+insurance, I guess.”
+
+“But,” objected Kennedy, “Schloss carried so little.”
+
+“Well, there was the Hale Protection. How about that?”
+
+Craig looked up quickly, unruffled by the patronizing air of the
+professional toward the amateur detective.
+
+“What is your theory?” he asked. “Do you think he robbed himself?”
+
+Winters shrugged his shoulders. “I’ve been interested in Schloss for
+some time,” he said enigmatically. “He has had some pretty swell
+customers. I’ll keep you wised up, if anything happens,” he added in a
+burst of graciousness, walking off.
+
+On the way to the subway, we paused again to see McLear.
+
+“Well,” he asked, “what do you think of it, now?”
+
+“All most extraordinary,” ruminated Craig. “And the queerest feature of
+all is that the chief loss consists of a diamond necklace that belonged
+once to Mrs. Antoinette Moulton.”
+
+“Mrs. Lynn Moulton?” repeated McLear.
+
+“The same,” assured Kennedy.
+
+McLear appeared somewhat puzzled. “Her husband is one of our old
+subscribers,” he pursued. “He is a lawyer on Wall Street and quite a
+gem collector. Last night his safe was tampered with, but this morning
+he reports no loss. Not half an hour ago he had us on the wire
+congratulating us on scaring off the burglars, if there had been any.”
+
+“What is your opinion,” I asked. “Is there a gang operating?”
+
+“My belief is,” he answered, reminiscently of his days on the detective
+force, “that none of the loot will be recovered until they start to
+‘fence’ it. That would be my lay—to look for the fence. Why, think of
+all the big robberies that have been pulled off lately. Remember,” he
+went on, “the spoils of a burglary consist generally of precious
+stones. They are not currency. They must be turned into currency—or
+what’s the use of robbery?
+
+“But merely to offer them for sale at an ordinary jeweler’s would be
+suspicious. Even pawnbrokers are on the watch. You see what I am
+driving at? I think there is a man or a group of men whose business it
+is to pay cash for stolen property and who have ways of returning gems
+into the regular trade channels. In all these robberies we get a
+glimpse of as dark and mysterious a criminal as has ever been recorded.
+He may be—anybody. About his legitimacy, I believe, no question has
+ever been raised. And, I tell you, his arrest is going to create a
+greater sensation than even the remarkable series of robberies that he
+has planned or made possible. The question is, to my mind, who is this
+fence?”
+
+McLear’s telephone rang and he handed the instrument to Craig.
+
+“Yes, this is Professor Kennedy,” answered Craig. “Oh, too bad you’ve
+had to try all over to get me. I’ve been going from one place to
+another gathering clues and have made good progress, considering I’ve
+hardly started. Why—what’s the matter? Really?”
+
+An interval followed, during which McLear left to answer a personal
+call on another wire.
+
+As Kennedy hung up the receiver, his face wore a peculiar look. “It was
+Mrs. Moulton,” he blurted out. “She thinks that her husband has found
+out that the necklace is paste.”
+
+“How?” I asked.
+
+“The paste replica is gone from her wall safe in the Deluxe.”
+
+I turned, startled at the information. Even Kennedy himself was
+perplexed at the sudden succession of events. I had nothing to say.
+
+Evidently, however, his rule was when in doubt play a trump, for,
+twenty minutes later found us in the office of Lynn Moulton, the famous
+corporation lawyer, in Wall Street.
+
+Moulton was a handsome man of past fifty with a youthful face against
+his iron gray hair and mustache, well dressed, genial, a man who seemed
+keenly in love with the good things of life.
+
+“It is rumored,” began Kennedy, “that an attempt was made on your safe
+here at the office last night.”
+
+“Yes,” he admitted, taking off his glasses and polishing them
+carefully. “I suppose there is no need of concealment, especially as I
+hear that a somewhat similar attempt was made on the safe of my friend
+Herman Schloss in Maiden Lane.”
+
+“You lost nothing?”
+
+Moulton put his glasses on and looked Kennedy in the face frankly.
+
+“Nothing, fortunately,” he said, then went on slowly. “You see, in my
+later years, I have been something of a collector of precious stones
+myself. I don’t wear them, but I have always taken the keenest pleasure
+in owning them and when I was married it gave me a great deal more
+pleasure to have them set in rings, pendants, tiaras, necklaces, and
+other forms for my wife.”
+
+He had risen, with the air of a busy man who had given the subject all
+the consideration he could afford and whose work proceeded almost by
+schedule. “This morning I found my safe tampered with, but, as I said,
+fortunately something must have scared off the burglars.”
+
+He bowed us out politely. What was the explanation, I wondered. It
+seemed, on the face of things, that Antoinette Moulton feared her
+husband. Did he know something else already, and did she know he knew?
+To all appearances he took it very calmly, if he did know. Perhaps that
+was what she feared, his very calmness.
+
+“I must see Mrs. Moulton again,” remarked Kennedy, as we left.
+
+The Moultons lived, we found, in one of the largest suites of a new
+apartment hotel, the Deluxe, and in spite of the fact that our arrival
+had been announced some minutes before we saw Mrs. Moulton, it was
+evident that she had been crying hysterically over the loss of the
+paste jewels and what it implied.
+
+“I missed it this morning, after my return from seeing you,” she
+replied in answer to Craig’s inquiry, then added, wide-eyed with alarm,
+“What shall I do? He must have opened the wall safe and found the
+replica. I don’t dare ask him point-blank.”
+
+“Are you sure he did it?” asked Kennedy, more, I felt, for its moral
+effect on her than through any doubt in his own mind.
+
+“Not sure. But then the wall safe shows no marks, and the replica is
+gone.”
+
+“Might I see your jewel case?” he asked.
+
+“Surely. I’ll get it. The wall safe is in Lynn’s room. I shall probably
+have to fuss a long time with the combination.”
+
+In fact she could not have been very familiar with it for it took
+several minutes before she returned. Meanwhile, Kennedy, who had been
+drumming absently on the arms of his chair, suddenly rose and walked
+quietly over to a scrap basket that stood beside an escritoire. It had
+evidently just been emptied, for the rooms must have been cleaned
+several hours before. He bent down over it and picked up two scraps of
+paper adhering to the wicker work. The rest had evidently been thrown
+away.
+
+I bent over to read them. One was:
+
+—rest Nettie—
+—dying to see—
+
+
+The other read:
+
+—cherche to-d
+—love and ma
+—rman.
+
+
+What did it mean? Hastily, I could fill in “Dearest Nettie,” and “I am
+dying to see you.” Kennedy added, “The Recherche to-day,” that being
+the name of a new apartment uptown, as well as “love and many kisses.”
+But “—rman”—what did that mean? Could it be Herman—Herman Schloss?
+
+She was returning and we resumed our seats quickly.
+
+Kennedy took the jewel case from her and examined it carefully. There
+was not a mark on it.
+
+“Mrs. Moulton,” he said slowly, rising and handing it back to her,
+“have you told me all?”
+
+“Why—yes,” she answered.
+
+Kennedy shook his head gravely.
+
+“I’m afraid not. You must tell me everything.”
+
+“No—no,” she cried vehemently, “there is nothing more.”
+
+We left and outside the Deluxe he paused, looked about, caught sight of
+a taxicab and hailed it.
+
+“Where?” asked the driver.
+
+“Across the street,” he said, “and wait. Put the window in back of you
+down so I can talk. I’ll tell you where to go presently. Now, Walter,
+sit back as far as you can. This may seem like an underhand thing to
+do, but we’ve got to get what that woman won’t tell us or give up the
+case.”
+
+Perhaps half an hour we waited, still puzzling over the scraps of
+paper. Suddenly I felt a nudge from Kennedy. Antoinette Moulton was
+standing in the doorway across the street. Evidently she preferred not
+to ride in her own car, for a moment later she entered a taxicab.
+
+“Follow that black cab,” said Kennedy to our driver.
+
+Sure enough, it stopped in front of the Recherche Apartments and Mrs.
+Moulton stepped out and almost ran in.
+
+We waited a moment, then Kennedy followed. The elevator that had taken
+her up had just returned to the ground floor.
+
+“The same floor again,” remarked Kennedy, jauntily stepping in and
+nodding familiarly to the elevator boy.
+
+Then he paused suddenly, looked at his watch, fixed his gaze
+thoughtfully on me an instant, and exclaimed. “By George—no. I can’t go
+up yet. I clean forgot that engagement at the hotel. One moment, son.
+Let us out. We’ll be back again.”
+
+Considerably mystified, I followed him to the sidewalk.
+
+“You’re entitled to an explanation,” he laughed catching my bewildered
+look as he opened the cab door. “I didn’t want to go up now while she
+is there, but I wanted to get on good terms with that boy. We’ll wait
+until she comes down, then go up.”
+
+“Where?” I asked.
+
+“That’s what I am going through all this elaborate preparation to find
+out. I have no more idea than you have.”
+
+It could not have been more than twenty minutes later when Mrs. Moulton
+emerged rather hurriedly, and drove away.
+
+While we had been waiting I had observed a man on the other side of the
+street who seemed unduly interested in the Recherche, too, for he had
+walked up and down the block no less than six times. Kennedy saw him,
+and as he made no effort to follow Mrs. Moulton, Kennedy did not do so
+either. In fact a little quick glance which she had given at our cab
+had raised a fear that she might have discovered that she was being
+followed.
+
+Kennedy and I paid off our cabman and sauntered into the Recherche in
+the most debonair manner we could assume.
+
+“Now, son, we’ll go up,” he said to the boy who, remembering us, and
+now not at all clear in his mind that he might not have seen us before
+that, whisked us to the tenth floor.
+
+“Let me see,” said Kennedy, “it’s number one hundred and—er——”
+
+“Three,” prompted the boy.
+
+He pressed the buzzer and a neatly dressed colored maid responded.
+
+“I had an appointment here with Mrs. Moulton this morning,” remarked
+Kennedy.
+
+“She has just gone,” replied the maid, off her guard.
+
+“And was to meet Mr. Schloss here in half an hour,” he added quickly.
+
+It was the maid’s turn to look surprised.
+
+“I didn’t think he was to be here,” she said. “He’s had some—”
+
+“Trouble at the office,” supplied Kennedy. “That’s what it was about.
+Perhaps he hasn’t been able to get away yet. But I had the appointment.
+Ah, I see a telephone in the hall. May I?”
+
+He had stepped politely in, and by dint of cleverly keeping his finger
+on the hook in the half light, he carried on a one-sided conversation
+with himself long enough to get a good chance to look about.
+
+There was an air of quiet and refinement about the apartment in the
+Recherche. It was darkened to give the little glowing electric bulbs in
+their silken shades a full chance to simulate right. The deep velvety
+carpets were noiseless to the foot, and the draperies, the pictures,
+the bronzes, all bespoke taste.
+
+But the chief objects of interest to Craig were the little square green
+baize-covered tables on one of which lay neatly stacked a pile of
+gilt-edged cards and a mahogany box full of ivory chips of red, white
+and blue.
+
+It was none of the old-time gambling places, like Danfield’s, with its
+steel door which Craig had once cut through with an oxyacetylene
+blowpipe in order to rescue a young spendthrift from himself.
+
+Kennedy seemed perfectly well satisfied merely with a cursory view of
+the place, as he hung up the receiver and thanked the maid politely for
+allowing him to use it.
+
+“This is up-to-date gambling in cleaned-up New York,” he remarked as we
+waited for the elevator to return for us. “And the worst of it all is
+that it gets the women as well as the men. Once they are caught in the
+net, they are the most powerful lure to men that the gamblers have yet
+devised.”
+
+We rode down in silence, and as we went down the steps to the street, I
+noticed the man whom we had seen watching the place, lurking down at
+the lower corner. Kennedy quickened his pace and came up behind him.
+
+“Why, Winters!” exclaimed Craig. “You here?”
+
+“I might say the same to you,” grinned the detective not displeased
+evidently that our trail had crossed his. “I suppose you are looking
+for Schloss, too. He’s up in the Recherche a great deal, playing poker.
+I understand he owns an interest in the game up there.”
+
+Kennedy nodded, but said nothing.
+
+“I just saw one of the cappers for the place go out before you went
+in.”
+
+“Capper?” repeated Kennedy surprised. “Antoinette Moulton a steerer for
+a gambling joint? What can a rich society woman have to do with a place
+like that or a man like Schloss?”
+
+Winters smiled sardonically. “Society ladies to-day often get into
+scrapes of which their husbands know nothing,” he remarked. “You didn’t
+know before that Antoinette Moulton, like many of her friends in the
+smart set, was a gambler—and loser—did you?”
+
+Craig shook his head. He had more of human than scientific interest in
+a case of a woman of her caliber gone wrong.
+
+“But you must have read of the famous Moulton diamonds?”
+
+“Yes,” said Craig, blankly, as if it were all news to him.
+
+“Schloss has them—or at least had them. The jewels she wore at the
+opera this winter were paste, I understand.”
+
+“Does Moulton play?” he asked.
+
+“I think so—but not here, naturally. In a way, I suppose, it is his
+fault. They all do it. The example of one drives on another.”
+
+Instantly there flashed over my mind a host of possibilities. Perhaps,
+after all, Winters had been right. Schloss had taken this way to make
+sure of the jewels so that she could not redeem them. Suddenly another
+explanation crowded that out. Had Mrs. Moulton robbed the safe herself,
+or hired some one else to do it for her, and had that person gone back
+on her?
+
+Then a horrid possibility occurred to me. Whatever Antoinette Moulton
+may have been and done, some one must have her in his power. What a
+situation for the woman! My sympathy went out to her in her supreme
+struggle. Even if it had been a real robbery, Schloss might easily
+recover from it. But for her every event spelled ruin and seemed only
+to be bringing that ruin closer.
+
+We left Winters, still watching on the trail of Schloss, and went on
+uptown to the laboratory.
+
+
+
+
+CHAPTER XVIII
+THE BURGLAR’S MICROPHONE
+
+
+That night I was sitting, brooding over the case, while Craig was
+studying a photograph which he made of the smudge on the glass door
+down at Schloss’. He paused in his scrutiny of the print to answer the
+telephone.
+
+“Something has happened to Schloss,” he exclaimed seizing his hat and
+coat. “Winters has been watching him. He didn’t go to the Recherche.
+Winters wants me to meet him at a place several blocks below it Come
+on. He wouldn’t say over the wire what it was. Hurry.”
+
+We met Winters in less than ten minutes at the address he had given, a
+bachelor apartment in the neighborhood of the Recherche.
+
+“Schloss kept rooms here,” explained Winters, hurrying us quickly
+upstairs. “I wanted you to see before anyone else.”
+
+As we entered the large and luxuriously furnished living room of the
+jeweler’s suite, a gruesome sight greeted us.
+
+There lay Schloss on the floor, face down, in a horribly contorted
+position. In one hand, clenched under him partly, the torn sleeve of a
+woman’s dress was grasped convulsively. The room bore unmistakable
+traces of a violent struggle, but except for the hideous object on the
+floor was vacant.
+
+Kennedy bent down over him. Schloss was dead. In a corner, by the door,
+stood a pile of grips, stacked up, packed, and undisturbed.
+
+Winters who had been studying the room while we got our bearings picked
+up a queer-looking revolver from the floor. As he held it up I could
+see that along the top of the barrel was a long cylinder with a ratchet
+or catch at the butt end. He turned it over and over carefully.
+
+“By George,” he muttered, “it has been fired off.”
+
+Kennedy glanced more minutely at the body. There was not a mark on it.
+I stared about vacantly at the place where Winters had picked the thing
+up.
+
+“Look,” I cried, my eye catching a little hole in the baseboard of the
+woodwork near it.
+
+“It must have fallen and exploded on the floor,” remarked Kennedy. “Let
+me see it, Winters.”
+
+Craig held it at arm’s length and pulled the catch. Instead of an
+explosion, there came a cone of light from the top of the gun. As
+Kennedy moved it over the wall, I saw in the center of the circle of
+light a dark spot.
+
+“A new invention,” Craig explained. “All you need to do is to move it
+so that little dark spot falls directly on an object. Pull the
+trigger—the bullet strikes the dark spot. Even a nervous and unskilled
+marksman becomes a good shot in the dark. He can even shoot from behind
+the protection of something—and hit accurately.”
+
+It was too much for me. I could only stand and watch Kennedy as he
+deftly bent over Schloss again and placed a piece of chemically
+prepared paper flat on the forehead of the dead man.
+
+When he withdrew it, I could see that it bore marks of the lines on his
+head. Without a word, Kennedy drew from his pocket a print of the
+photograph of the smudge on Schloss’ door.
+
+“It is possible,” he said, half to himself, “to identify a person by
+means of the arrangement of the sweat glands or pores. Poroscopy, Dr.
+Edmond Locard, director of the Police Laboratory at Lyons, calls it.
+The shape, arrangement, number per square centimeter, all vary in
+different individuals. Besides, here we have added the lines of the
+forehead.”
+
+He was studying the two impressions intensely. When he looked up from
+his examination, his face wore a peculiar expression.
+
+“This is not the head which was placed so close to the glass of the
+door of Schloss’ office, peering through, on the night of the robbery,
+in order to see before picking the lock whether the office was empty
+and everything ready for the hasty attack on the safe.”
+
+“That disposes of my theory that Schloss robbed himself,” remarked
+Winters reluctantly. “But the struggle here, the sleeve of the dress,
+the pistol—could he have been shot?”
+
+“No, I think not,” considered Kennedy. “It looks to me more like a case
+of apoplexy.”
+
+“What shall we do?” asked Winters. “Far from clearing anything up, this
+complicates it.”
+
+“Where’s Muller?” asked Kennedy. “Does he know? Perhaps he can shed
+some light on it.”
+
+The clang of an ambulance bell outside told that the aid summoned by
+Winters had arrived.
+
+We left the body in charge of the surgeon and of a policeman who
+arrived about the same time, and followed Winters.
+
+Muller lived in a cheap boarding house in a shabbily respectable street
+downtown, and without announcing ourselves we climbed the stairs to his
+room. He looked up surprised but not disconcerted as we entered.
+
+“What’s the matter?” he asked.
+
+“Muller,” shot out Winters, “we have just found Mr. Schloss dead!”
+
+“D-dead!” he stammered.
+
+The man seemed speechless with horror.
+
+“Yes, and with his grips packed as if to run away.”
+
+Muller looked dazedly from one of us to the other, but shut up like a
+clam.
+
+“I think you had better come along with us as a material witness,”
+burst out Winters roughly.
+
+Kennedy said nothing, leaving that sort of third degree work to the
+detective. But he was not idle, as Winters tried to extract more than
+the monosyllables, “I don’t know,” in answer to every inquiry of Muller
+about his employer’s life and business.
+
+A low exclamation from Craig attracted my attention from Winters. In a
+corner he had discovered a small box and had opened it. Inside was a
+dry battery and a most peculiar instrument, something like a little
+flat telephone transmitter yet attached by wires to earpieces that
+fitted over the head after the manner of those of a wireless detector.
+
+“What’s this?” asked Kennedy, dangling it before Muller.
+
+He looked at it phlegmatically. “A deaf instrument I have been working
+on,” replied the jeweler. “My hearing is getting poor.”
+
+Kennedy looked hastily from the instrument to the man.
+
+“I think I’ll take it along with us,” he said quietly.
+
+Winters, true to his instincts, had been searching Muller in the
+meantime. Besides the various assortment that a man carries in his
+pockets usually, including pens, pencils, notebooks, a watch, a
+handkerchief, a bunch of keys, one of which was large enough to open a
+castle, there was a bunch of blank and unissued pawn-tickets bearing
+the name, “Stein’s One Per Cent. a Month Loans,” and an address on the
+Bowery.
+
+Was Muller the “fence” we were seeking, or only a tool for the “fence”
+higher up? Who was this Stein?
+
+What it all meant I could only guess. It was a far cry from the wealth
+of Diamond Lane to a dingy Bowery pawnshop, even though pawnbroking at
+one per cent. a month—and more, on the side—pays. I knew, too, that
+diamonds are hoarded on the East Side as nowhere else in the world,
+outside of India. It was no uncommon thing, I had heard, for a
+pawnbroker whose shop seemed dirty and greasy to the casual visitor to
+have stored away in his vault gems running into the hundreds of
+thousands of dollars.
+
+“Mrs. Moulton must know of this,” remarked Kennedy. “Winters, you and
+Jameson bring Muller along. I am going up to the Deluxe.”
+
+I must say that I was surprised at finding Mrs. Moulton there. Outside
+the suite Winters and I waited with the unresisting Muller, while
+Kennedy entered. But through the door which he left ajar I could hear
+what passed.
+
+“Mrs. Moulton,” he began, “something terrible has happened—”
+
+He broke off, and I gathered that her pale face and agitated manner
+told him that she knew already.
+
+“Where is Mr. Moulton?” he went on, changing his question.
+
+“Mr. Moulton is at his office,” she answered tremulously. “He
+telephoned while I was out that he had to work to-night. Oh, Mr.
+Kennedy—he knows—he knows. I know it. He has avoided me ever since I
+missed the replica from-”
+
+“Sh!” cautioned Craig. He had risen and gone to the door.
+
+“Winters,” he whispered, “I want you to go down to Lynn Moulton’s
+office. Meanwhile Jameson can take care of Muller. I am going over to
+that place of Stein’s presently. Bring Moulton up there. You will wait
+here, Walter, for the present,” he nodded.
+
+He returned to the room where I could hear her crying softly.
+
+“Now, Mrs. Moulton,” he said gently, “I’m afraid I must trouble you to
+go with me. I am going over to a pawnbroker’s on the Bowery.”
+
+“The Bowery?” she repeated, with a genuinely surprised shudder. “Oh,
+no, Mr. Kennedy. Don’t ask me to go anywhere to-night. I am—I am in no
+condition to go anywhere—to do anything—I—”
+
+“But you must,” said Kennedy in a low voice.
+
+“I can’t. Oh—have mercy on me. I am terribly upset. You—”
+
+“It is your duty to go, Mrs. Moulton,” he repeated.
+
+“I don’t understand.” she murmured. “A pawnbroker’s?”
+
+“Come,” urged Kennedy, not harshly but firmly, then, as she held back,
+added, playing a trump card, “We must work quickly. In his hands we
+found the fragments of a torn dress. When the police—”
+
+She uttered a shriek. A glance had told her, if she had deceived
+herself before, that Kennedy knew her secret.
+
+Antoinette Moulton was standing before him, talking rapidly.
+
+“Some one has told Lynn. I know it. There is nothing now that I can
+conceal. If you had come half an hour later you would not have found
+me. He had written to Mr. Schloss, threatening him that if he did not
+leave the country he would shoot him at sight. Mr. Schloss showed me
+the letter.
+
+“It had come to this. I must either elope with Schloss, or lose his
+aid. The thought of either was unendurable. I hated him—yet was
+dependent on him.
+
+“To-night I met him, in his empty apartment, alone. I knew that he had
+what was left of his money with him, that everything was packed up. I
+went prepared. I would not elope. My plan was no less than to make him
+pay the balance on the necklace that he had lost—or to murder him.
+
+“I carried a new pistol in my muff, one which Lynn had just bought. I
+don’t know how I did it. I was desperate.
+
+“He told me he loved me, that Lynn did not, never had—that Lynn had
+married me only to show off his wealth and diamonds, to give him a
+social! position—that I was merely a—a piece of property—a dummy.
+
+“He tried to kiss me. It was revolting. I struggled away from him.
+
+“And in the struggle, the revolver fell from my muff and exploded on
+the floor.
+
+“At once he was aflame with suspicion.
+
+“‘So—it’s murder you want!’ he shouted. ‘Well, murder it shall be!’
+
+“I saw death in his eye as he seized my arm. I was defenseless now. The
+old passion came over him. Before he killed—he—would have his way with
+me.
+
+“I screamed. With a wild effort I twisted away from him.
+
+“He raised his hand to strike me, I saw his eyes, glassy. Then he sank
+back—fell to the floor—dead of apoplexy—dead of his furious emotions.
+
+“I fled.
+
+“And now you have found me.”
+
+She had turned, hastily, to leave the room. Kennedy blocked the door.
+
+“Mrs. Moulton,” he said firmly, “listen to me. What was the first
+question you asked me? ‘Can I trust you?’ And I told you you could.
+This is no time for—for suicide.” He shot the word out bluntly. “All
+may not be lost. I have sent for your husband. Muller is outside.”
+
+“Muller?” she cried. “He made the replica.”
+
+“Very well. I am going to clear this thing up. Come. You _must_.”
+
+It was all confused to me, the dash in a car to the little pawnbroker’s
+on the first floor of a five-story tenement, the quick entry into the
+place by one of Muller’s keys.
+
+Over the safe in back was a framework like that which had covered
+Schloss’ safe. Kennedy tore it away, regardless of the alarm which it
+must have sounded. In a moment he was down before it on his knees.
+
+“This is how Schloss’ safe was opened so quickly,” he muttered, working
+feverishly. “Here is some of their own medicine.”
+
+He had placed the peculiar telephone-like transmitter close to the
+combination lock and was turning the combination rapidly.
+
+Suddenly he rose, gave the bolts a twist, and the ponderous doors swung
+open.
+
+“What is it?” I asked eagerly.
+
+“A burglar’s microphone,” he answered, hastily looking over the
+contents of the safe. “The microphone is now used by burglars for
+picking combination locks. When you turn the lock, a slight sound is
+made when the proper number comes opposite the working point. It can be
+heard sometimes by a sensitive ear, although it is imperceptible to
+most persons. But by using a microphone it is an easy matter to hear
+the sounds which allow of opening the lock.”
+
+He had taken a yellow chamois bag out of the safe and opened it.
+
+Inside sparkled the famous Moulton diamonds. He held them up—in all
+their wicked brilliancy. No one spoke.
+
+Then he took another yellow bag, more dirty and worn than the first. As
+he opened it, Mrs. Moulton could restrain herself no longer.
+
+“The replica!” she cried. “The replica!”
+
+Without a word, Craig handed the real necklace to her. Then he slipped
+the paste jewels into the newer of the bags and restored both it and
+the empty one to their places, banged shut the door of the safe, and
+replaced the wooden screen.
+
+“Quick!” he said to her, “you have still a minute to get away.
+Hurry—anywhere—away—only away!”
+
+The look of gratitude that came over her face, as she understood the
+full meaning of it was such as I had never seen before.
+
+“Quick!” he repeated.
+
+It was too late.
+
+“For God’s sake, Kennedy,” shouted a voice at the street door, “what
+are you doing here?”
+
+It was McLear himself. He had come with the Hale patrol, on his mettle
+now to take care of the epidemic of robberies.
+
+Before Craig could reply a cab drew up with a rush at the curb and two
+men, half fighting, half cursing, catapulted themselves into the shop.
+
+They were Winters and Moulton.
+
+Without a word, taking advantage of the first shock of surprise,
+Kennedy had clapped a piece of chemical paper on the foreheads of Mrs.
+Moulton, then of Moulton, and on Muller’s. Oblivious to the rest of us,
+he studied the impressions in the full light of the counter.
+
+Moulton was facing his wife with a scornful curl of the lip.
+
+“I’ve been told of the paste replica—and I wrote Schloss that I’d shoot
+him down like the dog he is, you—you traitress,” he hissed.
+
+She drew herself up scornfully.
+
+“And I have been told why you married me—to show off your wicked jewels
+and help you in your—”
+
+“You lie!” he cried fiercely. “Muller—some one—open this safe—whosever
+it is. If what I have been told is true, there is in it one new bag
+containing the necklace. It was stolen from Schloss to whom you sold
+_my_ jewels. The other old bag, stolen from me, contains the paste
+replica you had made to deceive me.”
+
+It was all so confused that I do not know how it happened. I think it
+was Muller who opened the safe.
+
+“There is the new yellow bag,” cried Moulton, “from Schloss’ own safe.
+Open it.”
+
+McLear had taken it. He did so. There sparkled not the real gems, but
+the replica.
+
+“The devil!” Moulton exclaimed, breaking from Winters and seizing the
+old bag.
+
+He tore it open and—it was empty.
+
+“One moment,” interrupted Kennedy, looking up quietly from the counter.
+“Seal that safe again, McLear. In it are the Schloss jewels and the
+products of half a dozen other robberies which the dupe Muller—or
+Stein, as you please—pulled off, some as a blind to conceal the real
+criminal. You may have shown him how to leave no finger prints, but you
+yourself have left what is just as good—your own forehead print.
+McLear—you were right. There’s your criminal—Lynn Moulton, professional
+fence, the brains of the thing.”
+
+
+
+
+CHAPTER XIX
+THE GERM LETTER
+
+
+Lynn Moulton made no fight and Kennedy did not pursue the case, for,
+with the rescue of Antoinette Moulton, his interest ceased.
+
+Blackmail takes various forms, and the Moulton affair was only one
+phase of it. It was not long before we had to meet a much stranger
+attempt.
+
+“Read the letter, Professor Kennedy. Then I will tell you the sequel.”
+
+Mrs. Hunter Blake lay back in the cushions of her invalid chair in the
+sun parlor of the great Blake mansion on Riverside Drive, facing the
+Hudson with its continuous reel of maritime life framed against the
+green-hilled background of the Jersey shore.
+
+Her nurse, Miss Dora Sears, gently smoothed out the pillows and
+adjusted them so that the invalid could more easily watch us. Mrs.
+Blake, wealthy, known as a philanthropist, was not an old woman, but
+had been for years a great sufferer from rheumatism.
+
+I watched Miss Sears eagerly. Full-bosomed, fine of face and figure,
+she was something more than a nurse; she was a companion. She had
+bright, sparkling black eyes and an expression about her well-cut mouth
+which made one want to laugh with her. It seemed to say that the world
+was a huge joke and she invited you to enjoy the joke with her.
+
+Kennedy took the letter which Miss Sears proffered him, and as he did
+so I could not help noticing her full, plump forearm on which gleamed a
+handsome plain gold bracelet. He spread the letter out on a dainty
+wicker table in such a way that we both could see it.
+
+We had been summoned over the telephone to the Blake mansion by
+Reginald Blake, Mrs. Blake’s eldest son. Reginald had been very
+reticent over the reason, but had seemed very anxious and insistent
+that Kennedy should come immediately.
+
+Craig read quickly and I followed him, fascinated by the letter from
+its very opening paragraph.
+
+“Dear Madam,” it began. “Having received my diploma as doctor of
+medicine and bacteriology at Heidelberg in 1909, I came to the United
+States to study a most serious disease which is prevalent in several of
+the western mountain states.”
+
+So far, I reflected, it looked like an ordinary appeal for aid. The
+next words, however, were queer: “I have four hundred persons of wealth
+on my list. Your name was—”
+
+Kennedy turned the page. On the next leaf of the letter sheet was
+pasted a strip of gelatine. The first page had adhered slightly to the
+gelatine.
+
+“Chosen by fate,” went on the sentence ominously.
+
+“By opening this letter,” I read, “you have liberated millions of the
+virulent bacteria of this disease. Without a doubt you are infected by
+this time, for no human body is impervious to them, and up to the
+present only one in one hundred has fully recovered after going through
+all its stages.”
+
+I gasped. The gelatine had evidently been arranged so that when the two
+sheets were pulled apart, the germs would be thrown into the air about
+the person opening the letter. It was a very ingenious device.
+
+The letter continued, “I am happy to say, however, that I have a
+prophylactic which will destroy any number of these germs if used up to
+the ninth day. It is necessary only that you should place five thousand
+dollars in an envelope and leave it for me to be called for at the desk
+of the Prince Henry Hotel. When the messenger delivers the money to me,
+the prophylactic will be sent immediately.
+
+“First of all, take a match and burn this letter to avoid spreading the
+disease. Then change your clothes and burn the old ones. Enclosed you
+will find in a germ-proof envelope an exact copy of this letter. The
+room should then be thoroughly fumigated. Do not come into close
+contact with anyone near and dear to you until you have used the
+prophylactic. Tell no one. In case you do, the prophylactic will not be
+sent under any circumstances. Very truly yours, DR. HANS HOPF.”
+
+“Blackmail!” exclaimed Kennedy, looking intently again at the gelatine
+on the second page, as I involuntarily backed away and held my breath.
+
+“Yes, I know,” responded Mrs. Blake anxiously, “but is it true?”
+
+There could be no doubt from the tone of her voice that she more than
+half believed that it was true.
+
+“I cannot say—yet,” replied Craig, still cautiously scanning the
+apparently innocent piece of gelatine on the original letter which Mrs.
+Blake had not destroyed. “I shall have to keep it and examine it.”
+
+On the gelatine I could see a dark mass which evidently was supposed to
+contain the germs.
+
+“I opened the letter here in this room,” she went on. “At first I
+thought nothing of it. But this morning, when Buster, my prize
+Pekinese, who had been with me, sitting on my lap at the time, and
+closer to the letter even than I was, when Buster was taken suddenly
+ill, I—well, I began to worry.”
+
+She finished with a little nervous laugh, as people will to hide their
+real feelings.
+
+“I should like to see the dog,” remarked Kennedy simply.
+
+“Miss Sears,” asked her mistress, “will you get Buster, please?”
+
+The nurse left the room. No longer was there the laughing look on her
+face. This was serious business.
+
+A few minutes later she reappeared, carrying gingerly a small dog
+basket. Mrs. Blake lifted the lid. Inside was a beautiful little
+“Peke,” and it was easy to see that Buster was indeed ill.
+
+“Who is your doctor?” asked Craig, considering.
+
+“Dr. Rae Wilson, a very well-known woman physician.”
+
+Kennedy nodded recognition of the name. “What does she say?” he asked,
+observing the dog narrowly.
+
+“We haven’t told anyone, outside, of it yet,” replied Mrs. Blake. “In
+fact until Buster fell sick, I thought it was a hoax.”
+
+“You haven’t told anyone?”
+
+“Only Reginald and my daughter Betty. Betty is frantic—not with fear
+for herself, but with fear for me. No one can reassure her. In fact it
+was as much for her sake as anyone’s that I sent for you. Reginald has
+tried to trace the thing down himself, but has not succeeded.”
+
+She paused. The door opened and Reginald Blake entered. He was a young
+fellow, self confident and no doubt very efficient at the new dances,
+though scarcely fitted to rub elbows with a cold world which, outside
+of his own immediate circle, knew not the name of Blake. He stood for a
+moment regarding us through the smoke of his cigarette.
+
+“Tell me just what you have done,” asked Kennedy of him as his mother
+introduced him, although he had done the talking for her over the
+telephone.
+
+“Done?” he drawled. “Why, as soon as mother told me of the letter, I
+left an envelope up at the Prince Henry, as it directed.”
+
+“With the money?” put in Craig quickly.
+
+“Oh, no—just as a decoy.”
+
+“Yes. What happened?”
+
+“Well, I waited around a long time. It was far along in the day when a
+woman appeared at the desk. I had instructed the clerk to be on the
+watch for anyone who asked for mail addressed to a Dr. Hopf. The clerk
+slammed the register. That was the signal. I moved up closer.”
+
+“What did she look like?” asked Kennedy keenly.
+
+“I couldn’t see her face. But she was beautifully dressed, with a long
+light flowing linen duster, a veil that hid her features and on her
+hands and arms a long pair of motoring doeskin gloves. By George, she
+was a winner—in general looks, though. Well, something about the clerk,
+I suppose, must have aroused her suspicions. For, a moment later, she
+was gone in the crowd. Evidently she had thought of the danger and had
+picked out a time when the lobby would be full and everybody busy. But
+she did not leave by the front entrance through which she entered. I
+concluded that she must have left by one of the side street carriage
+doors.”
+
+“And she got away?”
+
+“Yes. I found that she asked one of the boys at the door to crank up a
+car standing at the curb. She slid into the seat, and was off in a
+minute.”
+
+Kennedy said nothing. But I knew that he was making a mighty effort to
+restrain comment on the bungling amateur detective work of the son of
+our client.
+
+Reginald saw the look on his face. “Still,” he hastened, “I got the
+number of the car. It was 200859 New York.”
+
+“You have looked it up?” queried Kennedy quickly.
+
+“I didn’t need to do it. A few minutes later Dr. Rae Wilson herself
+came out—storming like mad. Her car had been stolen at the very door of
+the hotel by this woman with the innocent aid of the hotel employees.”
+
+Kennedy was evidently keenly interested. The mention of the stolen car
+had apparently at once suggested an idea to him.
+
+“Mrs. Blake,” he said, as he rose to go, “I shall take this letter with
+me. Will you see that Buster is sent up to my laboratory immediately?”
+
+She nodded. It was evident that Buster was a great pet with her and
+that it was with difficulty she kept from smoothing his silky coat.
+
+“You—you won’t hurt Buster?” she pleaded.
+
+“No. Trust me. More than that, if there is any possible way of
+untangling this mystery, I shall do it.”
+
+Mrs. Blake looked rather than spoke her thanks. As we went downstairs,
+accompanied by Miss Sears, we could see in the music room a very
+interesting couple, chatting earnestly over the piano.
+
+Betty Blake, a slip of a girl in her first season, was dividing her
+attention between her visitor and the door by which we were passing.
+
+She rose as she heard us, leaving the young man standing alone at the
+piano. He was of an age perhaps a year or two older than Reginald
+Blake. It was evident that, whatever Miss Betty might think, he had
+eyes for no one else but the pretty debutante. He even seemed to be
+regarding Kennedy sullenly, as if he were a possible rival.
+
+“You—you don’t think it is serious?” whispered Betty in an undertone,
+scarcely waiting to be introduced. She had evidently known of our
+visit, but had been unable to get away to be present upstairs.
+
+“Really, Miss Blake,” reassured Kennedy, “I can’t say. All I can do is
+to repeat what I have already said to your mother. Keep up a good heart
+and trust me to work it out.”
+
+“Thank you,” she murmured, and then, impulsively extending her small
+hand to Craig, she added, “Mr. Kennedy, if there is anything I can do
+to help you, I beg that you will call on me.”
+
+“I shall not forget,” he answered, relinquishing the hand reluctantly.
+Then, as she thanked him, and turned again to her guest, he added in a
+low tone to me, “A remarkable girl, Walter, a girl that can be depended
+on.”
+
+We followed Miss Sears down the hall.
+
+“Who was that young man in the music room?” asked Kennedy, when we were
+out of earshot.
+
+“Duncan Baldwin,” she answered. “A friend and bosom companion of
+Reginald.”
+
+“He seems to think more of Betty than of her brother,” Craig remarked
+dryly.
+
+Miss Sears smiled. “Sometimes, we think they are secretly engaged,” she
+returned. We had almost reached the door. “By the way,” she asked
+anxiously, “do you think there are any precautions that I should take
+for Mrs. Blake—and the rest?”
+
+“Hardly,” answered Kennedy, after a moment’s consideration, “as long as
+you have taken none in particular already. Still, I suppose it will do
+no harm to be as antiseptic as possible.”
+
+“I shall try,” she promised, her face showing that she considered the
+affair now in a much more serious light than she had before our visit.
+
+“And keep me informed of anything that turns up,” added Kennedy handing
+her a card with the telephone number of the laboratory.
+
+As we left the Blake mansion, Kennedy remarked, “We must trace that car
+somehow—at least we must get someone working on that.”
+
+Half an hour later we were in a towering office building on Liberty
+Street, the home of various kinds of insurance. Kennedy stopped before
+a door which bore the name, “Douglas Garwood: Insurance Adjuster.”
+
+Briefly, Craig told the story of the stolen car, omitting the account
+of the dastardly method taken to blackmail Mrs. Blake. As he proceeded
+a light seemed to break on the face of Garwood, a heavyset man, whose
+very gaze was inquisitorial.
+
+“Yes, the theft has been reported to us already by Dr. Wilson herself,”
+he interrupted. “The car was insured in a company I represent.”
+
+“I had hoped so,” remarked Kennedy, “Do you know the woman?” he added,
+watching the insurance adjuster who had been listening intently as he
+told about the fair motor car thief.
+
+“Know her?” repeated Garwood emphatically. “Why, man, we have been so
+close to that woman that I feel almost intimate with her. The
+descriptions are those of a lady, well-dressed, and with a voice and
+manner that would carry her through any of the fashionable hotels,
+perhaps into society itself.”
+
+“One of a gang of blackmailers, then,” I hazarded.
+
+Garwood shrugged his shoulders. “Perhaps,” he acquiesced. “It is
+automobile thieving that interests me, though. Why,” he went on, rising
+excitedly, “the gangs of these thieves are getting away with half a
+million dollars’ worth of high-priced cars every year. The police seem
+to be powerless to stop it. We appeal to them, but with no result. So,
+now we have taken things into our own hands.”
+
+“What are you doing in this case?” asked Kennedy.
+
+“What the insurance companies have to do to recover stolen
+automobiles,” Garwood replied. “For, with all deference to your friend,
+Deputy O’Connor, it is the insurance companies rather than the police
+who get stolen cars back.”
+
+He had pulled out a postal card from a pigeon hole in his desk,
+selecting it from several apparently similar. We read:
+
+$250.00 REWARD
+
+
+We will pay $100.00 for car, $150.00 additional for information which
+will convict the thief. When last seen, driven by a woman, name not
+known, who is described as dark-haired, well-dressed, slight,
+apparently thirty years old. The car is a Dixon, 1912, seven-passenger,
+touring, No. 193,222, license No. 200,859, New York; dark red body,
+mohair top, brass lamps, has no wind shield; rear axle brake band
+device has extra nut on turnbuckle not painted. Car last seen near
+Prince Henry Hotel, New York City, Friday, the 10th.
+
+Communicate by telegraph or telephone, after notifying nearest police
+department, with Douglas Garwood, New York City.
+
+“The secret of it is,” explained Garwood, as we finished reading, “that
+there are innumerable people who keep their eyes open and like to earn
+money easily. Thus we have several hundreds of amateur and enthusiastic
+detectives watching all over the city and country for any car that
+looks suspicious.”
+
+Kennedy thanked him for his courtesy, and we rose to go. “I shall be
+glad to keep you informed of anything that turns up,” he promised.
+
+
+
+
+CHAPTER XX
+THE ARTIFICIAL KIDNEY
+
+
+In the laboratory, Kennedy quietly set to work. He began by tearing
+from the germ letter the piece of gelatine and first examining it with
+a pocket lens. Then, with a sterile platinum wire, he picked out
+several minute sections of the black spot on the gelatine and placed
+them in agar, blood serum, and other media on which they would be
+likely to grow.
+
+“I shall have to wait until to-morrow to examine them properly,” he
+remarked. “There are colonies of something there, all right, but I must
+have them more fully developed.”
+
+A hurried telephone call late in the day from Miss Sears told us that
+Mrs. Blake herself had begun to complain, and that Dr. Wilson had been
+summoned but had been unable to give an opinion on the nature of the
+malady.
+
+Kennedy quickly decided on making a visit to the doctor, who lived not
+far downtown from the laboratory.
+
+Dr. Rae Wilson proved to be a nervous little woman, inclined, I felt,
+to be dictatorial. I thought that secretly she felt a little piqued at
+our having been taken into the Blakes’ confidence before herself, and
+Kennedy made every effort to smooth that aspect over tactfully.
+
+“Have you any idea what it can be?” he asked finally.
+
+She shook her head noncommittally. “I have taken blood smears,” she
+answered, “but so far haven’t been able to discover anything. I shall
+have to have her under observation for a day or two before I can answer
+that. Still, as Mrs. Blake is so ill, I have ordered another trained
+nurse to relieve Miss Sears of the added work, a very efficient nurse,
+a Miss Rogers.”
+
+Kennedy had risen to go. “You have had no word about your car?” he
+asked casually.
+
+“None yet. I’m not worrying. It was insured.”
+
+“Who is this arch criminal, Dr. Hopf?” I mused as we retraced our steps
+to the laboratory. “Is Mrs. Blake stricken now by the same trouble that
+seems to have affected Buster?”
+
+“Only my examination will show,” he said. “I shall let nothing
+interfere with that now. It must be the starting point for any work
+that I may do in the case.”
+
+We arrived at Kennedy’s workshop of scientific crime and he immediately
+plunged into work. Looking up he caught sight of me standing helplessly
+idle.
+
+“Walter,” he remarked thoughtfully adjusting a microscope, “suppose you
+run down and see Garwood. Perhaps he has something to report. And by
+the way, while you are out, make inquiries about the Blakes, young
+Baldwin, Miss Sears and this Dr. Wilson. I have heard of her before, at
+least by name. Perhaps you may find something interesting.”
+
+Glad to have a chance to seem to be doing something whether it amounted
+to anything or not, I dropped in to see Garwood. So far he had nothing
+to report except the usual number of false alarms. From his office I
+went up to the _Star_ where fortunately I found one of the reporters
+who wrote society notes.
+
+The Blakes, I found, as we already knew, to be well known and moving in
+the highest social circles. As far as known they had no particular
+enemies, other than those common to all people of great wealth. Dr.
+Wilson had a large practice, built up in recent years, and was one of
+the best known society physicians for women. Miss Sears was unknown, as
+far as I could determine. As for Duncan Baldwin, I found that he had
+become acquainted with Reginald Blake in college, that he came of no
+particular family and seemed to have no great means, although he was
+very popular in the best circles. In fact he had had, thanks to his
+friend, a rather meteoric rise in society, though it was reported that
+he was somewhat involved in debt as a result.
+
+I returned to the laboratory to find that Craig had taken out of a
+cabinet a peculiar looking arrangement. It consisted of thirty-two
+tubes, each about sixteen inches long, with S-turns, like a minute
+radiator. It was altogether not over a cubic foot in size, and enclosed
+in a glass cylinder. There were in it, perhaps, fifty feet of tubes, a
+perfectly-closed tubular system which I noticed Kennedy was keeping
+absolutely sterile in a germicidal solution of some kind.
+
+Inside the tubes and surrounding them was a saline solution which was
+kept at a uniform temperature by a special heating apparatus.
+
+Kennedy had placed the apparatus on the laboratory table and then
+gently took the little dog from his basket and laid him beside it. A
+few minutes later the poor little suffering Buster was mercifully under
+the influence of an anesthetic.
+
+Quickly Craig worked. First he attached the end of one of the tubes by
+means of a little cannula to the carotid artery of the dog. Then the
+other was attached to the jugular vein.
+
+As he released the clamp which held the artery, the little dog’s
+feverishly beating heart spurted the arterial blood from the carotid
+into the tubes holding the normal salt solution and that pressure, in
+turn, pumped the salt solution which filled the tubes into the jugular
+vein, thus replacing the arterial blood that had poured into the tubes
+from the other end and maintaining the normal hydrostatic conditions in
+the body circulation. The dog was being kept alive, although perhaps a
+third of his blood was out of his body.
+
+“You see,” he said at length, after we had watched the process a few
+minutes, “what I have here is in reality an artificial kidney. It is a
+system that has been devised by several doctors at Johns Hopkins.
+
+“If there is any toxin in the blood of this dog, the kidneys are
+naturally endeavoring to eliminate it. Perhaps it is being eliminated
+too slowly. In that case this arrangement which I have here will aid
+them. We call it vividiffusion and it depends for its action on the
+physical principle of osmosis, the passage of substances of a certain
+kind through a porous membrane, such as these tubes of celloidin.
+
+“Thus any substance, any poison that is dialyzable is diffused into the
+surrounding salt solution and the blood is passed back into the body,
+with no air in it, no infection, and without alteration. Clotting is
+prevented by the injection of a harmless substance derived from
+leeches, known as hirudin. I prevent the loss of anything in the blood
+which I want retained by placing in the salt solution around the tubes
+an amount of that substance equal to that held in solution by the
+blood. Of course that does not apply to the colloidal substances in the
+blood which would not pass by osmosis under any circumstances. But by
+such adjustments I can remove and study any desired substance in the
+blood, provided it is capable of diffusion. In fact this little
+apparatus has been found in practice to compare favorably with the
+kidneys themselves in removing even a lethal dose of poison.”
+
+I watched in amazement. He was actually cleaning the blood of the dog
+and putting it back again, purified, into the little body. Far from
+being cruel, as perhaps it might seem, it was in reality probably the
+only method by which the animal could be saved, and at the same time it
+was giving us a clue as to some elusive, subtle substance used in the
+case.
+
+“Indeed,” Kennedy went on reflectively, “this process can be kept up
+for several hours without injury to the dog, though I do not think that
+will be necessary to relieve the unwonted strain that has been put upon
+his natural organs. Finally, at the close of the operation, serious
+loss of blood is overcome by driving back the greater part of it into
+his body, closing up the artery and vein, and taking good care of the
+animal so that he will make a quick recovery.”
+
+For a long time I watched the fascinating process of seeing the life
+blood coursing through the porous tubes in the salt solution, while
+Kennedy gave his undivided attention to the success of the delicate
+experiment. It was late when I left him, still at work over Buster, and
+went up to our apartment to turn in, convinced that nothing more would
+happen that night.
+
+The next morning, with characteristic energy, Craig was at work early,
+examining the cultures he had made from the black spots on the
+gelatine.
+
+By the look of perplexity on his face, I knew that he had discovered
+something that instead of clearing the mystery up, further deepened it.
+
+“What do you find?” I asked anxiously.
+
+“Walter,” he exclaimed, laying aside the last of the slides which he
+had been staining and looking at intently through the microscope, “that
+stuff on the gelatine is entirely harmless. There was nothing in it
+except common mold.”
+
+For the moment I did not comprehend. “Mold?” I repeated.
+
+“Yes,” he replied, “just common, ordinary mold such as grows on the top
+of a jar of fruit or preserves when it is exposed to the air.”
+
+I stifled an exclamation of incredulity. It seemed impossible that the
+deadly germ note should be harmless, in view of the events that had
+followed its receipt.
+
+Just then the laboratory door was flung open and Reginald Blake, pale
+and excited, entered. He had every mark of having been up all night.
+
+“What’s the matter?” asked Craig.
+
+“It’s about my mother,” he blurted out. “She seems to be getting worse
+all the time. Miss Sears is alarmed, and Betty is almost ill herself
+with worry. Dr. Wilson doesn’t seem to know what it is that affects
+her, and neither does the new nurse. Can’t you _do_ something?”
+
+There was a tone of appeal in his voice that was not like the
+self-sufficient Reginald of the day before.
+
+“Does there seem to be any immediate danger?” asked Kennedy.
+
+“Perhaps not—I can’t say,” he urged. “But she is gradually getting
+worse instead of better.”
+
+Kennedy thought a moment. “Has anything else happened?” he asked
+slowly.
+
+“N-no. That’s enough, isn’t it?”
+
+“Indeed it is,” replied Craig, trying to be reassuring. Then,
+recollecting Betty, he added, “Reginald, go back and tell your sister
+for me that she must positively make the greatest effort of her life to
+control herself. Tell her that her mother needs her—needs her well and
+brave. I shall be up at the house immediately. Do the best you can. I
+depend on you.”
+
+Kennedy’s words seemed to have a bracing effect on Reginald and a few
+moments later he left, much calmer.
+
+“I hope I have given him something to do which will keep him from
+mussing things up again,” remarked Kennedy, mindful of Reginald’s
+former excursion into detective work.
+
+Meanwhile Craig plunged furiously into his study of the substances he
+had isolated from the saline solution in which he had “washed” the
+blood of the little Pekinese.
+
+“There’s no use doing anything in the dark,” he explained. “Until we
+know what it is we are fighting we can’t very well fight.”
+
+For the moment I was overwhelmed by the impending tragedy that seemed
+to be hanging over Mrs. Blake. The more I thought of it, the more
+inexplicable became the discovery of the mold.
+
+“That is all very well about the mold on the gelatine strip in the
+letter,” I insisted at length. “But, Craig, there must be something
+wrong somewhere. Mere molds could not have made Buster so ill, and now
+the infection, or whatever it is, has spread to Mrs. Blake herself.
+What have you found out by studying Buster?”
+
+He looked up from his close scrutiny of the material in one of the test
+tubes which contained something he had recovered from the saline
+solution of the diffusion apparatus.
+
+I could read on his face that whatever it was, it was serious. “What is
+it?” I repeated almost breathlessly.
+
+“I suppose I might coin a word to describe it,” he answered slowly,
+measuring his phrases. “Perhaps it might be called
+hyper-amino-acidemia.”
+
+I puckered my eyes at the mouth-filling term Kennedy smiled. “It would
+mean,” he explained, “a great quantity of the amino-acids,
+non-coagulable, nitrogenous compounds in the blood. You know the
+indols, the phenols, and the amins are produced both by putrefactive
+bacteria and by the process of metabolism, the burning up of the
+tissues in the process of utilizing the energy that means life. But
+under normal circumstances, the amins are not present in the blood in
+any such quantities as I have discovered by this new method of
+diffusion.”
+
+He paused a moment, as if in deference to my inability to follow him on
+such an abstruse topic, then resumed, “As far as I am able to
+determine, this poison or toxin is an amin similar to that secreted by
+certain cephalopods found in the neighborhood of Naples. It is an
+aromatic amin. Smell it.”
+
+I bent over and inhaled the peculiar odor.
+
+“Those creatures,” he continued, “catch their prey by this highly
+active poison secreted by the so-called salivary glands. Even a little
+bit will kill a crab easily.”
+
+I was following him now with intense interest, thinking of the
+astuteness of a mind capable of thinking of such a poison.
+
+“Indeed, it is surprising,” he resumed thoughtfully, “how many an
+innocent substance can be changed by bacteria into a virulent poison.
+In fact our poisons and our drugs are in many instances the close
+relations of harmless compounds that represent the intermediate steps
+in the daily process of metabolism.”
+
+“Then,” I put in, “the toxin was produced by germs, after all?”
+
+“I did not say that,” he corrected. “It might have been. But I find no
+germs in the blood of Buster. Nor did Dr. Wilson find any in the blood
+smears which she took from Mrs. Blake.”
+
+He seemed to have thrown the whole thing back again into the limbo of
+the unexplainable, and I felt nonplussed.
+
+“The writer of that letter,” he went on, waving the piece of sterile
+platinum wire with which he had been transferring drops of liquid in
+his search for germs, “was a much more skillful bacteriologist than I
+thought, evidently. No, the trouble does not seem to be from germs
+breathed in, or from germs at all—it is from some kind of germ-free
+toxin that has been injected or otherwise introduced.”
+
+Vaguely now I began to appreciate the terrible significance of what he
+had discovered.
+
+“But the letter?” I persisted mechanically.
+
+“The writer of that was quite as shrewd a psychologist as
+bacteriologist,” pursued Craig impressively. “He calculated the moral
+effect of the letter, then of Buster’s illness, and finally of reaching
+Mrs. Blake herself.”
+
+“You think Dr. Rae Wilson knows nothing of it yet?” I queried.
+
+Kennedy appeared to consider his answer carefully. Then he said slowly:
+“Almost any doctor with a microscope and the faintest trace of a
+scientific education could recognize disease germs either naturally or
+feloniously implanted. But when it comes to the detection of
+concentrated, filtered, germ-free toxins, almost any scientist might be
+baffled. Walter,” he concluded, “this is not mere blackmail, although
+perhaps the visit of that woman to the Prince Henry—a desperate thing
+in itself, although she did get away by her quick thinking—perhaps that
+shows that these people are ready to stop at nothing. No, it goes
+deeper than blackmail.”
+
+I stood aghast at the discovery of this new method of scientific
+murder. The astute criminal, whoever he might be, had planned to leave
+not even the slender clue that might be afforded by disease germs. He
+was operating, not with disease itself, but with something showing the
+ultimate effects, perhaps, of disease with none of the preliminary
+symptoms, baffling even to the best of physicians.
+
+I scarcely knew what to say. Before I realized it, however, Craig was
+at last ready for the promised visit to Mrs. Blake. We went together,
+carrying Buster, in his basket, not recovered, to be sure, but a very
+different little animal from the dying creature that had been sent to
+us at the laboratory.
+
+
+
+
+CHAPTER XXI
+THE POISON BRACELET
+
+
+We reached the Blake mansion and were promptly admitted. Miss Betty,
+bearing up bravely under Reginald’s reassurances, greeted us before we
+were fairly inside the door, though she and her brother were not able
+to conceal the fact that their mother was no better. Miss Sears was
+out, for an airing, and the new nurse, Miss Rogers, was in charge of
+the patient.
+
+“How do you feel, this morning?” inquired Kennedy as we entered the
+sun-parlor, where Mrs. Blake had first received us.
+
+A single glance was enough to satisfy me of the seriousness of her
+condition. She seemed to be in almost a stupor from which she roused
+herself only with difficulty. It was as if some overpowering toxin were
+gradually undermining her already weakened constitution.
+
+She nodded recognition, but nothing further.
+
+Kennedy had set the dog basket down near her wheel-chair and she caught
+sight of it.
+
+“Buster?” she murmured, raising her eyes. “Is—he—all right?”
+
+For answer, Craig simply raised the lid of the basket. Buster already
+seemed to have recognized the voice of his mistress, and, with an
+almost human instinct, to realize that though he himself was still weak
+and ill, she needed encouragement.
+
+As Mrs. Blake stretched out her slender hand, drawn with pain, to his
+silky head, he gave a little yelp of delight and his little red tongue
+eagerly caressed her hand.
+
+It was as though the two understood each other. Although Mrs. Blake, as
+yet, had no more idea what had happened to her pet, she seemed to feel
+by some subtle means of thought transference that the intelligent
+little animal was conveying to her a message of hope. The caress, the
+sharp, joyous yelp, and the happy wagging of the bushy tail seemed to
+brighten her up, at least for the moment, almost as if she had received
+a new impetus.
+
+“Buster!” she exclaimed, overjoyed to get her pet back again in so much
+improved condition.
+
+“I wouldn’t exert myself too much, Mrs. Blake,” cautioned Kennedy.
+
+“Were—were there any germs in the letter?” she asked, as Reginald and
+Betty stood on the other side of the chair, much encouraged,
+apparently, at this show of throwing off the lethargy that had seized
+her.
+
+“Yes, but about as harmless as those would be on a piece of cheese,”
+Kennedy hastened. “But I—I feel so weak, so played out—and my head—”
+
+Her voice trailed off, a too evident reminder that her improvement had
+been only momentary and prompted by the excitement of our arrival.
+
+Betty bent down solicitously and made her more comfortable as only one
+woman can make another. Kennedy, meanwhile, had been talking to Miss
+Rogers, and I could see that he was secretly taking her measure.
+
+“Has Dr. Wilson been here this morning?” I heard him ask.
+
+“Not yet,” she replied. “But we expect her soon.”
+
+“Professor Kennedy?” announced a servant.
+
+“Yes?” answered Craig.
+
+“There is someone on the telephone who wants to speak to you. He said
+he had called the laboratory first and that they told him to call you
+here.”
+
+Kennedy hurried after the servant, while Betty and Reginald joined me,
+waiting, for we seemed to feel that something was about to happen.
+
+“One of the unofficial detectives has unearthed a clue,” he whispered
+to me a few moments later when he returned. “It was Garwood.” Then to
+the others he added, “A car, repainted, and with the number changed,
+but otherwise answering the description of Dr. Wilson’s has been traced
+to the West Side. It is somewhere in the neighborhood of a saloon and
+garage where drivers of taxicabs hang out. Reginald, I wish you would
+come along with us.”
+
+To Betty’s unspoken question Craig hastened to add, “I don’t think
+there is any immediate danger. If there is any change—let me know. I
+shall call up soon. And meanwhile,” he lowered his voice to impress the
+instruction on her, “don’t leave your mother for a moment—not for a
+moment,” he emphasized.
+
+Reginald was ready and together we three set off to meet Garwood at a
+subway station near the point where the car had been reported. We had
+scarcely closed the front door, when we ran into Duncan Baldwin, coming
+down the street, evidently bent on inquiring how Mrs. Blake and Betty
+were.
+
+“Much better,” reassured Kennedy. “Come on, Baldwin. We can’t have too
+many on whom we can rely on an expedition like this.”
+
+“Like what?” he asked, evidently not comprehending.
+
+“There’s a clue, they think, to that car of Dr. Wilson’s,” hastily
+explained Reginald, linking his arm into that of his friend and falling
+in behind us, as Craig hurried ahead.
+
+It did not take long to reach the subway, and as we waited for the
+train, Craig remarked: “This is a pretty good example of how the
+automobile is becoming one of the most dangerous of criminal weapons.
+All one has to do nowadays, apparently, after committing a crime, is to
+jump into a waiting car and breeze away, safe.”
+
+We met Garwood and under his guidance picked our way westward from the
+better known streets in the heart of the city, to a section that was
+anything but prepossessing.
+
+The place which Garwood sought was a typical Raines Law hotel on a
+corner, with a saloon on the first floor, and apparently the requisite
+number of rooms above to give it a legal license.
+
+We had separated a little so that we would not attract undue attention.
+Kennedy and I entered the swinging doors boldly, while the others
+continued across to the other corner to wait with Garwood and take in
+the situation. It was a strange expedition and Reginald was fidgeting
+while Duncan seemed nervous.
+
+Among the group of chauffeurs lounging at the bar and in the back room
+anyone who had ever had any dealings with the gangs of New York might
+have recognized the faces of men whose pictures were in the rogues’
+gallery and who were members of those various aristocratic
+organizations of the underworld.
+
+Kennedy glanced about at the motley crowd. “This is a place where you
+need only to be introduced properly,” he whispered to me, “to have any
+kind of crime committed for you.”
+
+As we stood there, observing, without appearing to do so, through an
+open window on the side street I could tell from the sounds that there
+was a garage in the rear of the hotel.
+
+We were startled to hear a sudden uproar from the street.
+
+Garwood, impatient at our delay, had walked down past the garage to
+reconnoiter. A car was being backed out hurriedly, and as it turned and
+swung around the corner, his trained eye had recognized it.
+
+Instantly he had reasoned that it was an attempt to make a getaway, and
+had raised an alarm.
+
+Those nearest the door piled out, keen for any excitement. We, too,
+dashed out on the street. There we saw passing an automobile, swaying
+and lurching at the terrific speed with which its driver, urged it up
+the avenue. As he flashed by he looked like an Italian to me, perhaps a
+gunman.
+
+Garwood had impressed a passing trolley car into service and was
+pursuing the automobile in it, as it swayed on its tracks as crazily as
+the motor did on the roadway, running with all the power the motorman
+could apply.
+
+A mounted policeman galloped past us, blazing away at the tires. The
+avenue was stirred, as seldom even in its strenuous life, with reports
+of shots, honking of horns, the clang of trolley bells and the shouts
+of men.
+
+The pursuers were losing when there came a rattle and roar from the
+rear wheels which told that the tires were punctured and the heavy car
+was riding on its rims. A huge brewery wagon crossing a side street
+paused to see the fun, effectually blocking the road.
+
+The car jolted to a stop. The chauffeur leaped out and a moment later
+dived down into a cellar. In that congested district, pursuit was
+useless.
+
+“Only an accomplice,” commented Kennedy. “Perhaps we can get him some
+other way if we can catch the man—or woman—higher up.”
+
+Down the street now we could see Garwood surrounded by a curious crowd
+but in possession of the car. I looked about for Duncan and Reginald.
+They had apparently been swallowed up in the crowds of idlers which
+seemed to be pouring out of nowhere, collecting to gape at the
+excitement, after the manner of a New York crowd.
+
+As I ran my eye over them, I caught sight of Reginald near the corner
+where we had left him in an incipient fight with someone who had a
+fancied grievance. A moment later we had rescued him.
+
+“Where’s Duncan?” he panted. “Did anything happen to him? Garwood told
+us to stay here—but we got separated.”
+
+Policemen had appeared on the heels of the crowd and now, except for a
+knot following Garwood, things seemed to be calming down.
+
+The excitement over, and the people thinning out, Kennedy still could
+not find any trace of Duncan. Finally he glanced in again through the
+swinging doors. There was Duncan, evidently quite upset by what had
+occurred, fortifying himself at the bar.
+
+Suddenly from above came a heavy thud, as if someone had fallen on the
+floor above us, followed by a suppressed shuffling of feet and a cry of
+help.
+
+Kennedy sprang toward a side door which led out into the hall to the
+hotel room above. It was locked. Before any of the others he ran out on
+the street and into the hall that way, taking the stairs two at a time,
+past a little cubby-hole of an “office” and down the upper hall to a
+door from which came the cry.
+
+It was a peculiar room into which we burst, half bedroom, half
+workshop, or rather laboratory, for on a deal table by a window stood a
+rack of test-tubes, several beakers, and other paraphernalia.
+
+A chambermaid was shrieking over a woman who was lying lethargic on the
+floor.
+
+I looked more closely.
+
+It was Dora Sears.
+
+For the moment I could not imagine what had happened. Had the events of
+the past few days worked on her mind and driven her into temporary
+insanity? Or had the blackmailing gang of automobile thieves, failing
+in extorting money by their original plan, seized her?
+
+Kennedy bent over and tried to lift her up. As he did so, the gold
+bracelet, unclasped, clattered to the floor.
+
+He picked it up and for a moment looked at it. It was hollow, but in
+that part of it where it unclasped could be seen a minute hypodermic
+needle and traces of a liquid.
+
+“A poison bracelet,” he muttered to himself, “one in which enough of a
+virulent poison could be hidden so that in an emergency death could
+cheat the law.”
+
+“But this Dr. Hopf,” exclaimed Reginald, who stood behind us looking
+from the insensible girl to the bracelet and slowly comprehending what
+it all meant, “she alone knows where and who he is!”
+
+We looked at Kennedy. What was to be done? Was the criminal higher up
+to escape because one of his tools had been cornered and had taken the
+easiest way to get out?
+
+Kennedy had taken down the receiver of the wall telephone in the room.
+A moment later he was calling insistently for his laboratory. One of
+the students in another part of the building answered. Quickly he
+described the apparatus for vividiffusion and how to handle it without
+rupturing any of the delicate tubes.
+
+“The large one,” he ordered, “with one hundred and ninety-two tubes.
+And hurry.”
+
+Before the student appeared, came an ambulance which some one in the
+excitement had summoned. Kennedy quickly commandeered both the young
+doctor and what surgical material he had with him.
+
+Briefly he explained what he proposed to do and before the student
+arrived with the apparatus, they had placed the nurse in such a
+position that they were ready for the operation.
+
+The next room which was unoccupied had been thrown open to us and there
+I waited with Reginald and Duncan, endeavoring to explain to them the
+mysteries of the new process of washing the blood.
+
+The minutes lengthened into hours, as the blood of the poisoned girl
+coursed through its artificial channel, literally being washed of the
+toxin from the poisoned bracelet.
+
+Would it succeed? It had saved the life of Buster. But would it bring
+back the unfortunate before us, long enough even for her to yield her
+secret and enable us to catch the real criminal. What if she died?
+
+As Kennedy worked, the young men with me became more and more
+fascinated, watching him. The vividiffusion apparatus was now in full
+operation.
+
+In the intervals when he left the apparatus in charge of the young
+ambulance surgeon Kennedy was looking over the room. In a trunk which
+was open he found several bundles of papers. As he ran his eye over
+them quickly, he selected some and stuffed them into his pocket, then
+went back to watch the working of the apparatus.
+
+Reginald, who had been growing more and more nervous, at last asked if
+he might call up Betty to find out how his mother was.
+
+He came back from the telephone, his face wrinkled.
+
+“Poor mother,” he remarked anxiously, “do you think she will pull
+through, Professor? Betty says that Dr. Wilson has given her no idea
+yet about the nature of the trouble.”
+
+Kennedy thought a moment. “Of course,” he said, “your mother has had no
+such relative amount of the poison as Buster has had. I think that
+undoubtedly she will recover by purely natural means. I hope so. But if
+not, here is the apparatus,” and he patted the vividiffusion tubes in
+their glass case, “that will save her, too.”
+
+As well as I could I explained to Reginald the nature of the toxin that
+Kennedy had discovered. Duncan listened, putting in a question now and
+then. But it was evident that his thoughts were on something else, and
+now and then Reginald, breaking into his old humor, rallied him about
+thinking of Betty.
+
+A low exclamation from both Kennedy and the surgeon attracted us.
+
+Dora Sears had moved.
+
+The operation of the apparatus was stopped, the artery and vein had
+been joined up, and she was slowly coming out from under the effects of
+the anesthetic.
+
+As we gathered about her, at a little distance, we heard her cry in her
+delirium, “I—I would have—done—anything—for him.”
+
+We strained our ears. Was she talking of the blackmailer, Dr. Hopf?
+
+“Who?” asked Craig, bending over close to her ear.
+
+“I—I would—have done anything,” she repeated as if someone had
+contradicted her. She went on, dreamily, ramblingly, “He—is—is—my
+brother. I—”
+
+She stopped through weakness.
+
+“Where is Dr. Hopf?” asked Kennedy, trying to recall her fleeting
+attention.
+
+“Dr. Hopf? Dr. Hopf?” she repeated, then smiling to herself as people
+will when they are leaving the borderline of anesthesia, she repeated
+the name, “Hopf?”
+
+“Yes,” persisted Kennedy.
+
+“There is no Dr. Hopf,” she added. “Tell me—did—did they—”
+
+“No Dr. Hopf?” Kennedy insisted.
+
+She had lapsed again into half insensibility.
+
+He rose and faced us, speaking rapidly.
+
+“New York seems to have a mysterious and uncanny attraction for odds
+and ends of humanity, among them the great army of adventuresses. In
+fact there often seems to be something decidedly adventurous about the
+nursing profession. This is a girl of unusual education in medicine.
+Evidently she has traveled—her letters show it. Many of them show that
+she has been in Italy. Perhaps it was there that she heard of the drug
+that has been used in this case. It was she who injected the germ-free
+toxin, first into the dog, then into Mrs. Blake, she who wrote the
+blackmail letter which was to have explained the death.”
+
+He paused. Evidently she had heard dimly, was straining every effort to
+hear. In her effort she caught sight of our faces.
+
+Suddenly, as if she had seen an apparition, she raised herself with
+almost superhuman strength.
+
+“Duncan!” she cried. “Duncan! Why—didn’t you—get away—while there was
+time—after you warned me?”
+
+Kennedy had wheeled about and was facing us. He was holding in his hand
+some of the letters he had taken from the trunk. Among others was a
+folded piece of parchment that looked like a diploma. He unfolded it
+and we bent over to read.
+
+It was a diploma from the Central Western College of Nursing. As I read
+the name written in, it was with a shock. It was not Dora Sears, but
+Dora Baldwin.
+
+“A very clever plot,” he ground out, taking a step nearer us. “With the
+aid of your sister and a disreputable gang of chauffeurs you planned to
+hasten the death of Mrs. Blake, to hasten the inheritance of the Blake
+fortune by your future wife. I think your creditors will have less
+chance of collecting now than ever, Duncan Baldwin.”
+
+
+
+
+CHAPTER XXII
+THE DEVIL WORSHIPERS
+
+
+Tragic though the end of the young nurse, Dora Baldwin, had been, the
+scheme of her brother, in which she had become fatally involved, was by
+no means as diabolical as that in the case that confronted us a short
+time after that.
+
+I recall this case particularly not only because it was so weird but
+also because of the unique manner in which it began.
+
+“I am damned—Professor Kennedy—damned!”
+
+The words rang out as the cry of a lost soul. A terrible look of
+inexpressible anguish and fear was written on the face of Craig’s
+visitor, as she uttered them and sank back, trembling, in the easy
+chair, mentally and physically convulsed.
+
+As nearly as I had been able to follow, Mrs. Veda Blair’s story had
+dealt mostly with a Professor and Madame Rapport and something she
+called the “Red Lodge” of the “Temple of the Occult.”
+
+She was not exactly a young woman, although she was a very attractive
+one. She was of an age that is, perhaps, even more interesting than
+youth.
+
+Veda Blair, I knew, had been, before her recent marriage to Seward
+Blair, a Treacy, of an old, though somewhat unfortunate, family. Both
+the Blairs and the Treacys had been intimate and old Seward Blair, when
+he died about a year before, had left his fortune to his son on the
+condition that he marry Veda Treacy.
+
+“Sometimes,” faltered Mrs. Blair, “it is as though I had two souls. One
+of them is dispossessed of its body and the use of its organs and is
+frantic at the sight of the other that has crept in.”
+
+She ended her rambling story, sobbing the terrible words, “Oh—I have
+committed the unpardonable sin—I am anathema—I am damned—damned!”
+
+She said nothing of what terrible thing she had done and Kennedy, for
+the present, did not try to lead the conversation. But of all the
+stories that I have heard poured forth in the confessional of the
+detective’s office, hers, I think, was the wildest.
+
+Was she insane? At least I felt that she was sincere. Still, I wondered
+what sort of hallucination Craig had to deal with, as Veda Blair
+repeated the incoherent tale of her spiritual vagaries.
+
+Almost, I had begun to fancy that this was a case for a doctor, not for
+a detective, when suddenly she asked a most peculiar question.
+
+“Can people affect you for good or evil, merely by thinking about you?”
+she queried. Then a shudder passed over her. “They may be thinking
+about me now!” she murmured in terror.
+
+Her fear was so real and her physical distress so evident that Kennedy,
+who had been listening silently for the most part, rose and hastened to
+reassure her.
+
+“Not unless you make your own fears affect yourself and so play into
+their hands,” he said earnestly.
+
+Veda looked at him a moment, then shook her head mournfully. “I have
+seen Dr. Vaughn,” she said slowly.
+
+Dr. Gilbert Vaughn, I recollected, was a well-known alienist in the
+city.
+
+“He tried to tell me the same thing,” she resumed doubtfully. “But—oh—I
+know what I know! I have felt the death thought—and he knows it!”
+
+“What do you mean?” inquired Kennedy, leaning forward keenly.
+
+“The death thought,” she repeated, “a malicious psychic attack. Some
+one is driving me to death by it. I thought I could fight it off. I
+went away to escape it. Now I have come back—and I have not escaped.
+There is always that disturbing influence—always—directed against me. I
+know it will—kill me!”
+
+I listened, startled. The death thought! What did it mean? What
+terrible power was it? Was it hypnotism? What was this fearsome, cruel
+belief, this modern witchcraft that could unnerve a rich and educated
+woman? Surely, after all, I felt that this was not a case for a doctor
+alone; it called for a detective.
+
+“You see,” she went on, heroically trying to control herself, “I have
+always been interested in the mysterious, the strange, the occult. In
+fact my father and my husband’s father met through their common
+interest. So, you see, I come naturally by it.
+
+“Not long ago I heard of Professor and Madame Rapport and their new
+Temple of the Occult. I went to it, and later Seward became interested,
+too. We have been taken into a sort of inner circle,” she continued
+fearfully, as though there were some evil power in the very words
+themselves, “the Red Lodge.”
+
+“You have told Dr. Vaughn?” shot out Kennedy suddenly, his eyes fixed
+on her face to see what it would betray.
+
+Veda leaned forward, as if to tell a secret, then whispered in a low
+voice, “He knows. Like us—he—he is a—Devil Worshiper!”
+
+“What?” exclaimed Kennedy in wide-eyed astonishment.
+
+“A Devil Worshiper,” she repeated. “You haven’t heard of the Red
+Lodge?”
+
+Kennedy nodded negatively. “Could you get us—initiated?” he hazarded.
+
+“P—perhaps,” she hesitated, in a half-frightened tone. “I—I’ll try to
+get you in to-night.”
+
+She had risen, half dazed, as if her own temerity overwhelmed her.
+
+“You—poor girl,” blurted out Kennedy, his sympathies getting the upper
+hand for the moment as he took the hand she extended mutely. “Trust me.
+I will do all in my power, all in the power of modern science to help
+you fight off this—influence.”
+
+There must have been something magnetic, hypnotic in his eye.
+
+“I will stop here for you,” she murmured, as she almost fled from the
+room.
+
+Personally, I cannot say that I liked the idea of spying. It is not
+usually clean and wholesome. But I realized that occasionally it was
+necessary.
+
+“We are in for it now,” remarked Kennedy half humorously, half
+seriously, “to see the Devil in the twentieth century.”
+
+“And I,” I added, “I am, I suppose, to be the reporter to Satan.”
+
+We said nothing more about it, but I thought much about it, and the
+more I thought, the more incomprehensible the thing seemed. I had heard
+of Devil Worship, but had always associated it with far-off Indian and
+other heathen lands—in fact never among Caucasians in modern times,
+except possibly in Paris. Was there such a cult here in my own city? I
+felt skeptical.
+
+That night, however, promptly at the appointed time, a cab called for
+us, and in it was Veda Blair, nervous but determined.
+
+“Seward has gone ahead,” she explained. “I told him that a friend had
+introduced you, that you had studied the occult abroad. I trust you to
+carry it out.”
+
+Kennedy reassured her.
+
+The curtains were drawn and we could see nothing outside, though we
+must have been driven several miles, far out into the suburbs.
+
+At last the cab stopped. As we left it we could see nothing of the
+building, for the cab had entered a closed courtyard.
+
+“Who enters the Red Lodge?” challenged a sepulchral voice at the
+porte-cochère. “Give the password!”
+
+“The Serpent’s Tooth,” Veda answered.
+
+“Who are these?” asked the voice.
+
+“Neophytes,” she replied, and a whispered parley followed.
+
+“Then enter!” announced the voice at length.
+
+It was a large room into which we were first ushered, to be inducted
+into the rites of Satan.
+
+There seemed to be both men and women, perhaps half a dozen votaries.
+Seward Blair was already present. As I met him, I did not like the look
+in his eye; it was too stary. Dr. Vaughn was there, too, talking in a
+low tone to Madame Rapport. He shot a quick look at us. His were not
+eyes but gimlets that tried to bore into your very soul. Chatting with
+Seward Blair was a Mrs. Langhorne, a very beautiful woman. To-night she
+seemed to be unnaturally excited.
+
+All seemed to be on most intimate terms, and, as we waited a few
+minutes, I could not help recalling a sentence from Huysmans: “The
+worship of the Devil is no more insane than the worship of God. The
+worshipers of Satan are mystics—mystics of an unclean sort, it is true,
+but mystics none the less.”
+
+I did not agree with it, and did not repeat it, of course, but a moment
+later I overheard Dr. Vaughn saying to Kennedy: “Hoffman brought the
+Devil into modern life. Poe forgoes the aid of demons and works
+patiently and precisely by the scientific method. But the result is the
+same.”
+
+“Yes,” agreed Kennedy for the sake of appearances, “in a sense, I
+suppose, we are all devil worshipers in modern society—always have
+been. It is fear that rules and we fear the bad—not the good.”
+
+As we waited, I felt, more and more, the sense of the mysterious, the
+secret, the unknown which have always exercised a powerful attraction
+on the human mind. Even the aeroplane and the submarine, the X-ray and
+wireless have not banished the occult.
+
+In it, I felt, there was fascination for the frivolous and deep appeal
+to the intellectual and spiritual. The Temple of the Occult had
+evidently been designed to appeal to both types. I wondered how, like
+Lucifer, it had fallen. The prime requisite, I could guess already,
+however, was—money. Was it in its worship of the root of all evil that
+it had fallen?
+
+We passed soon into another room, hung entirely in red, with weird,
+cabalistic signs all about, on the walls. It was uncanny, creepy.
+
+A huge reproduction in plaster of one of the most sardonic of Notre
+Dame’s gargoyles seemed to preside over everything—a terrible figure in
+such an atmosphere.
+
+As we entered, we were struck by the blinding glare of the light, in
+contrast with the darkened room in which we had passed our brief
+novitiate, if it might be called such.
+
+Suddenly the lights were extinguished.
+
+The great gargoyle shone with an infernal light of its own!
+
+“Phosphorescent paint,” whispered Kennedy to me.
+
+Still, it did not detract from the weird effect to know what caused it.
+
+There was a startling noise in the general hush.
+
+“Sata!” cried one of the devotees.
+
+A door opened and there appeared the veritable priest of the Devil—pale
+of face, nose sharp, mouth bitter, eyes glassy.
+
+“That is Rapport,” Vaughn whispered to me.
+
+The worshipers crowded forward.
+
+Without a word, he raised his long, lean forefinger and began to single
+them out impressively. As he did so, each spoke, as if imploring aid.
+
+He came to Mrs. Langhorne.
+
+“I have tried the charm,” she cried earnestly, “and the one whom I love
+still hates me, while the one I hate loves me!”
+
+“Concentrate!” replied the priest, “concentrate! Think always ‘I love
+him. He must love me. I want him to love me. I love him. He must love
+me.’ Over and over again you must think it. Then the other side, ‘I
+hate him. He must leave me. I want him to leave me. I hate him—hate
+him.’”
+
+Around the circle he went.
+
+At last his lean finger was outstretched at Veda. It seemed as if some
+imp of the perverse were compelling her unwilling tongue to unlock its
+secrets.
+
+“Sometimes,” she cried in a low, tremulous voice, “something seems to
+seize me, as if by the hand and urge me onward. I cannot flee from it.”
+
+“Defend yourself!” answered the priest subtly. “When you know that some
+one is trying to kill you mentally, defend yourself! Work against it by
+every means in your power. Discourage! Intimidate! Destroy!”
+
+I marveled at these cryptic utterances. They shadowed a modern Black
+Art, of which I had had no conception—a recrudescence in other language
+of the age-old dualism of good and evil. It was a sort of mental
+malpractice.
+
+“Over and over again,” he went on speaking to her, “the same thought is
+to be repeated against an enemy. ‘You know you are going to die! You
+know you are going to die!’ Do it an hour, two hours, at a time. Others
+can help you, all thinking in unison the same thought.”
+
+What was this, I asked myself breathlessly—a new transcendental
+toxicology?
+
+Slowly, a strange mephitic vapor seemed to exhale into the room—or was
+it my heightened imagination?
+
+
+
+
+CHAPTER XXIII
+THE PSYCHIC CURSE
+
+
+There came a sudden noise—nameless—striking terror, low, rattling. I
+stood rooted to the spot. What was it that held me? Was it an atavistic
+joy in the horrible or was it merely a blasphemous curiosity?
+
+I scarcely dared to look.
+
+At last I raised my eyes. There was a live snake, upraised, his fangs
+striking out viciously—a rattler!
+
+I would have drawn back and fled, but Craig caught my arm.
+
+“Caged,” he whispered monosyllabically.
+
+I shuddered. This, at least, was no drawing-room diablerie.
+
+“It is Ophis,” intoned Rapport, “the Serpent—the one active form in
+Nature that cannot be ungraceful!”
+
+The appearance of the basilisk seemed to heighten the tension.
+
+At last it broke loose and then followed the most terrible blasphemies.
+The disciples, now all frenzied, surrounded closer the priest, the
+gargoyle and the serpent.
+
+They worshiped with howls and obscenities. Mad laughter mingled with
+pale fear and wild scorn in turns were written on the hectic faces
+about me.
+
+They had risen—it became a dance, a reel.
+
+The votaries seemed to spin about on their axes, as it were, uttering a
+low, moaning chant as they whirled. It was a mania, the spirit of
+demonism. Something unseen seemed to urge them on.
+
+Disgusted and stifled at the surcharged atmosphere, I would have tried
+to leave, but I seemed frozen to the spot. I could think of nothing
+except Poe’s Masque of the Red Death.
+
+Above all the rest whirled Seward Blair himself. The laugh of the
+fiend, for the moment, was in his mouth. An instant he stood—the oracle
+of the Demon—devil-possessed. Around whirled the frantic devotees,
+howling.
+
+Shrilly he cried, “The Devil is in me!”
+
+Forward staggered the devil dancer—tall, haggard, with deep sunken eyes
+and matted hair, face now smeared with dirt and blood-red with the
+reflection of the strange, unearthly phosphorescence.
+
+He reeled slowly through the crowd, crooning a quatrain, in a low,
+monotonous voice, his eyelids drooping and his head forward on his
+breast:
+
+If the Red Slayer think he slays,
+ Or the slain think he is slain,
+They know not well the subtle ways
+ I keep and pass and turn again!
+
+
+Entranced the whirling crowd paused and watched. One of their number
+had received the “power.”
+
+He was swaying slowly to and fro.
+
+“Look!” whispered Kennedy.
+
+His fingers twitched, his head wagged uncannily. Perspiration seemed to
+ooze from every pore. His breast heaved.
+
+He gave a sudden yell—ear-piercing. Then followed a screech of hellish
+laughter.
+
+The dance had ended, the dancers spellbound at the sight.
+
+He was whirling slowly, eyes protruding now, mouth foaming, chest
+rising and falling like a bellows, muscles quivering.
+
+Cries, vows, imprecations, prayers, all blended in an infernal hubbub.
+
+With a burst of ghastly, guttural laughter, he shrieked, “I _am_ the
+Devil!”
+
+His arms waved—cutting, sawing, hacking the air.
+
+The votaries, trembling, scarcely moved, breathed, as he danced.
+
+Suddenly he gave a great leap into the air—then fell, motionless. They
+crowded around him. The fiendish look was gone—the demoniac laughter
+stilled.
+
+It was over.
+
+The tension of the orgy had been too much for us. We parted, with
+scarcely a word, and yet I could feel that among the rest there was a
+sort of unholy companionship.
+
+Silently, Kennedy and I drove away in the darkened cab, this time with
+Seward and Veda Blair and Mrs. Langhorne.
+
+For several minutes not a word was said. I was, however, much occupied
+in watching the two women. It was not because of anything they said or
+did. That was not necessary. But I felt that there was a feud,
+something that set them against each other.
+
+“How would Rapport use the death thought, I wonder?” asked Craig
+speculatively, breaking the silence.
+
+Blair answered quickly. “Suppose some one tried to break away, to
+renounce the Lodge, expose its secrets. They would treat him so as to
+make him harmless—perhaps insane, confused, afraid to talk, paralyzed,
+or even to commit suicide or be killed in an accident. They would put
+the death thought on him!”
+
+Even in the prosaic jolting of the cab, away from the terrible
+mysteries of the Red Lodge, one could feel the spell.
+
+The cab stopped. Seward was on his feet in a moment and handing Mrs.
+Langhorne out at her home. For a moment they paused on the steps for an
+exchange of words.
+
+In that moment I caught flitting over the face of Veda a look of
+hatred, more intense, more real, more awful than any that had been
+induced under the mysteries of the rites at the Lodge.
+
+It was gone in an instant, and as Seward rejoined us I felt that, with
+Mrs. Langhorne gone, there was less restraint. I wondered whether it
+was she who had inspired the fear in Veda.
+
+Although it was more comfortable, the rest of our journey was made in
+silence and the Blairs dropped us at our apartment with many
+expressions of cordiality as we left them to proceed to their own.
+
+“Of one thing I’m sure,” I remarked, entering the room where only a few
+short hours before Mrs. Blair had related her strange tale. “Whatever
+the cause of it, the devil dancers don’t sham.”
+
+Kennedy did not reply. He was apparently wrapped up in the
+consideration of the remarkable events of the evening.
+
+As for myself, it was a state of affairs which, the day before, I
+should have pronounced utterly beyond the wildest bounds of the
+imagination of the most colorful writer. Yet here it was; I had seen
+it.
+
+I glanced up to find Kennedy standing by the light examining something
+he had apparently picked up at the Red Lodge. I bent over to look at
+it, too. It was a little glass tube.
+
+“An ampoule, I believe the technical name of such a container is,” he
+remarked, holding it closer to the light.
+
+In it were the remains of a dried yellow substance, broken up minutely,
+resembling crystals.
+
+“Who dropped it?” I asked.
+
+“Vaughn, I think,” he replied. “At least, I saw him near Blair,
+stooping over him, at the end, and I imagine this is what I saw
+gleaming for an instant in the light.”
+
+Kennedy said nothing more, and for my part I was thoroughly at sea and
+could make nothing out of it all.
+
+“What object can such a man as Dr. Vaughn possibly have in frequenting
+such a place?” I asked at length, adding, “And there’s that Mrs.
+Langhorne—she was interesting, too.”
+
+Kennedy made no direct reply. “I shall have them shadowed to-morrow,”
+he said briefly, “while I am at work in the laboratory over this
+ampoule.”
+
+As usual, also, Craig had begun on his scientific studies long before I
+was able to shake myself loose from the nightmares that haunted me
+after our weird experience of the evening.
+
+He had already given the order to an agency for the shadowing, and his
+next move was to start me out, also, looking into the history of those
+concerned in the case. As far as I was able to determine, Dr. Vaughn
+had an excellent reputation, and I could find no reason whatever for
+his connection with anything of the nature of the Red Lodge. The
+Rapports seemed to be nearly unknown in New York, although it was
+reported that they had come from Paris lately. Mrs. Langhorne was a
+divorcée from one of the western states, but little was known about
+her, except that she always seemed to be well supplied with money. It
+seemed to be well known in the circle in which Seward Blair moved that
+he was friendly with her, and I had about reached the conclusion that
+she was unscrupulously making use of his friendship, perhaps was not
+above such a thing as blackmail.
+
+Thus the day passed, and we heard no word from Veda Blair, although
+that was explained by the shadows, whose trails crossed in a most
+unexpected manner. Their reports showed that there was a meeting at the
+Red Lodge during the late afternoon, at which all had been present
+except Dr. Vaughn. We learned also from them the exact location of the
+Lodge, in an old house just across the line in Westchester.
+
+It was evidently a long and troublesome analysis that Craig was engaged
+in at the laboratory, for it was some hours after dinner that night
+when he came into the apartment, and even then he said nothing, but
+buried himself in some of the technical works with which his library
+was stocked. He said little, but I gathered that he was in great doubt
+about something, perhaps, as much as anything, about how to proceed
+with so peculiar a case.
+
+It was growing late, and Kennedy was still steeped in his books, when
+the door of the apartment, which we happened to have left unlocked, was
+suddenly thrown open and Seward Blair burst in on us, wildly excited.
+
+“Veda is gone!” he cried, before either of us could ask him what was
+the matter.
+
+“Gone?” repeated Kennedy. “How—where?”
+
+“I don’t know,” Blair blurted out breathlessly. “We had been out
+together this afternoon, and I returned with her. Then I went out to
+the club after dinner for a while, and when I got back I missed her—not
+quarter of an hour ago. I burst into her room—and there I found this
+note. Read it. I don’t know what to do. No one seems to know what has
+become of her. I’ve called up all over and then thought perhaps you
+might help me, might know some friend of hers that I don’t know, with
+whom she might have gone out.”
+
+Blair was plainly eager for us to help him. Kennedy took the paper from
+him. On it, in a trembling hand, were scrawled some words, evidently
+addressed to Blair himself:
+
+“You would forgive me and pity me if you knew what I have been through.
+
+“When I refused to yield my will to the will of the Lodge I suppose I
+aroused the enmity of the Lodge.
+
+“To-night as I lay in bed, alone, I felt that my hour had come, that
+mental forces that were almost irresistible were being directed against
+me.
+
+“I realized that I must fight not only for my sanity but for my life.
+
+“For hours I have fought that fight.
+
+“But during those hours, some one, I won’t say who, seemed to have
+developed such psychic faculties of penetration that they were able to
+make their bodies pass through the walls of my room.
+
+“At last I am conquered. I pray that you—”
+
+The writing broke off abruptly, as if she had left it in wild flight.
+
+“What does that mean?” asked Kennedy, “the ‘will of the Lodge’?”
+
+Blair looked at us keenly. I fancied that there was even something
+accusatory in the look. “Perhaps it was some mental reservation on her
+part,” he suggested. “You do not know yourself of any reason why she
+should fear anything, do you?” he asked pointedly.
+
+Kennedy did not betray even by the motion of an eyelash that we knew
+more than we should ostensibly.
+
+There was a tap at the door. I sprang to open it, thinking perhaps,
+after all, it was Veda herself.
+
+Instead, a man, a stranger, stood there.
+
+“Is this Professor Kennedy?” he asked, touching his hat.
+
+Craig nodded.
+
+“I am from the psychopathic ward of the City Hospital—an orderly, sir,”
+the man introduced.
+
+“Yes,” encouraged Craig, “what can I do for you?”
+
+“A Mrs. Blair has just been brought in, sir, and we can’t find her
+husband. She’s calling for you now.”
+
+Kennedy stared from the orderly to Seward Blair, startled, speechless.
+
+“What has happened?” asked Blair anxiously. “I am Mr. Blair.”
+
+The orderly shook his head. He had delivered his message. That was all
+he knew.
+
+“What do you suppose it is?” I asked, as we sped across town in a
+taxicab. “Is it the curse that she dreaded?”
+
+Kennedy said nothing and Blair appeared to hear nothing. His face was
+drawn in tense lines.
+
+The psychopathic ward is at once one of the most interesting and one of
+the most depressing departments of a large city hospital, harboring, as
+it does, all from the more or less harmless insane to violent
+alcoholics and wrecked drug fiends.
+
+Mrs. Blair, we learned, had been found hatless, without money, dazed,
+having fallen, after an apparently aimless wandering in the streets.
+
+For the moment she lay exhausted on the white bed of the ward, eyes
+glazed, pupils contracted, pulse now quick, now almost evanescent, face
+drawn, breathing difficult, moaning now and then in physical and mental
+agony.
+
+Until she spoke it was impossible to tell what had happened, but the
+ambulance surgeon had found a little red mark on her white forearm and
+had pointed it out, evidently with the idea that she was suffering from
+a drug.
+
+At the mere sight of the mark, Blair stared as though hypnotized.
+Leaning over to Kennedy, so that the others could not hear, he
+whispered, “It is the mark of the serpent!”
+
+Our arrival had been announced to the hospital physician, who entered
+and stood for a moment looking at the patient.
+
+“I think it is a drug—a poison,” he said meditatively.
+
+“You haven’t found out yet what it is, then?” asked Craig.
+
+The physician shook his head doubtfully. “Whatever it is,” he said
+slowly, “it is closely allied to the cyanide groups in its rapacious
+activity. I haven’t the slightest idea of its true nature, but it seems
+to have a powerful affinity for important nerve centers of respiration
+and muscular coordination, as well as for disorganizing the blood. I
+should say that it produces death by respiratory paralysis and
+convulsions. To my mind it is an exact, though perhaps less active,
+counterpart of hydrocyanic acid.”
+
+Kennedy had been listening intently at the start, but before the
+physician had finished he had bent over and made a ligature quickly
+with his handkerchief.
+
+Then he dispatched a messenger with a note. Next he cut about the
+minute wound on her arm until the blood flowed, cupping it to increase
+the flow. Now and then he had them administer a little stimulant.
+
+He had worked rapidly, while Blair watched him with a sort of
+fascination.
+
+“Get Dr. Vaughn,” ordered Craig, as soon as he had a breathing spell
+after his quick work, adding, “and Professor and Madame Rapport.
+Walter, attend to that, will you? I think you will find an officer
+outside. You’ll have to compel them to come, if they won’t come
+otherwise,” he added, giving the address of the Lodge, as we had found
+it.
+
+Blair shot a quick look at him, as though Craig in his knowledge were
+uncanny. Apparently, the address had been a secret which he thought we
+did not know.
+
+I managed to find an officer and dispatch him for the Rapports. A
+hospital orderly, I thought, would serve to get Dr. Vaughn.
+
+
+
+
+CHAPTER XXIV
+THE SERPENT’S TOOTH
+
+
+I had scarcely returned to the ward when, suddenly, an unnatural
+strength seemed to be infused into Veda.
+
+She had risen in bed.
+
+“It shall not catch me!” she cried in a new paroxysm of nameless
+terror. “No—no—it is pursuing me. I am never out of its grasp. I have
+been thought six feet underground—I know it. There it is again—still
+driving me—still driving me!
+
+“Will it never stop? Will no one stop it? Save me! It—is the death
+thought!”
+
+She had risen convulsively and had drawn back in abject, cowering
+terror. What was it she saw? Evidently it was very real and very awful.
+It pursued her relentlessly.
+
+As she lay there, rolling her eyes about, she caught sight of us and
+recognized us for the first time, although she had been calling for us.
+
+“They had the thought on you, too, Professor Kennedy,” she almost
+screamed. “Hour after hour, Rapport and the rest repeated over and over
+again, ‘Why does not some one kill him? Why does he not die?’ They knew
+you—even when I brought you to the Red Lodge. They thought you were a
+spy.”
+
+I turned to Kennedy. He had advanced and was leaning over to catch
+every word. Blair was standing behind me and she had not seen her
+husband yet. A quick glance showed me that he was trembling from head
+to foot like a leaf, as though he, too, were pursued by the nameless
+terror.
+
+“What did they do?” Kennedy asked in a low tone.
+
+Fearfully, gripping the bars of the iron bed, as though they were some
+tangible support for her mind, she answered: “They would get together.
+‘Now, all of you,’ they said, ‘unite yourselves in thought against our
+enemy, against Kennedy, that he must leave off persecuting us. He is
+ripe for destruction!’”
+
+Kennedy glanced sidewise at me, with a significant look.
+
+“God grant,” she implored, “that none haunt me for what I have done in
+my ignorance!”
+
+Just then the door opened and my messenger entered, accompanied by Dr.
+Vaughn.
+
+I had turned to catch the expression on Blair’s face just in time. It
+was a look of abject appeal.
+
+Before Dr. Vaughn could ask a question, or fairly take in the
+situation, Kennedy had faced him.
+
+“What was the purpose of all that elaborate mummery out at the Red
+Lodge?” asked Kennedy pointblank.
+
+I think I looked at Craig in no less amazement than Vaughn. In spite of
+the dramatic scenes through which we had passed, the spell of the
+occult had not fallen on him for an instant.
+
+“Mummery?” repeated Dr. Vaughn, bending his penetrating eyes on
+Kennedy, as if he would force him to betray himself first.
+
+“Yes,” reiterated Craig. “You know as well as I do that it has been
+said that it is a well-established fact that the world wants to be
+deceived and is willing to pay for the privilege.”
+
+Dr. Vaughn still gazed from one to the other of us defiantly.
+
+“You know what I mean,” persisted Kennedy, “the mumbo-jumbo—just as the
+Haitian obi man sticks pins in a doll or melts a wax figure of his
+enemy. That is supposed to be an outward sign. But back of this
+terrible power that people believe moves in darkness and mystery is
+something tangible—something real.”
+
+Dr. Vaughn looked up sharply at him, I think mistaking Kennedy’s
+meaning. If he did, all doubt that Kennedy attributed anything to the
+supernatural was removed as he went on: “At first I had no explanation
+of the curious events I have just witnessed, and the more I thought
+about them, the more obscure did they seem.
+
+“I have tried to reason the thing out,” he continued thoughtfully. “Did
+auto-suggestion, self-hypnotism explain what I have seen? Has Veda
+Blair been driven almost to death by her own fears only?”
+
+No one interrupted and he answered his own question. “Somehow the idea
+that it was purely fear that had driven her on did not satisfy me. As I
+said, I wanted something more tangible. I could not help thinking that
+it was not merely subjective. There was something objective, some force
+at work, something more than psychic in the result achieved by this
+criminal mental marauder, whoever it is.”
+
+I was following Kennedy’s reasoning now closely. As he proceeded, the
+point that he was making seemed more clear to me.
+
+Persons of a certain type of mind could be really mentally unbalanced
+by such methods which we had heard outlined, where the mere fact of
+another trying to exert power over them became known to them. They
+would, as a matter of fact, unbalance themselves, thinking about and
+fighting off imaginary terrors.
+
+Such people, I could readily see, might be quickly controlled, and in
+the wake of such control would follow stifled love, wrecked homes,
+ruined fortunes, suicide and even death.
+
+Dr. Vaughn leaned forward critically. “What did you conclude, then, was
+the explanation of what you saw last night?” he asked sharply.
+
+Kennedy met his question squarely, without flinching. “It looks to me,”
+he replied quietly, “like a sort of hystero-epilepsy. It is well known,
+I believe, to demonologists—those who have studied this sort of thing.
+They have recognized the contortions, the screams, the wild,
+blasphemous talk, the cataleptic rigidity. They are epileptiform.”
+
+Vaughn said nothing, but continued to weigh Kennedy as if in a balance.
+I, who knew him, knew that it would take a greater than Vaughn to find
+him wanting, once Kennedy chose to speak. As for Vaughn, was he trying
+to hide behind some technicality in medical ethics?
+
+“Dr. Vaughn,” continued Craig, as if goading him to the point of
+breaking down his calm silence, “you are specialist enough to know
+these things as well, better than I do. You must know that epilepsy is
+one of the most peculiar diseases.
+
+“The victim may be in good physical condition, apparently. In fact,
+some hardly know that they have it. But it is something more than
+merely the fits. Always there is something wrong mentally. It is not
+the motor disturbance so much as the disturbance of consciousness.”
+
+Kennedy was talking slowly, deliberately, so that none could drop a
+link in the reasoning.
+
+“Perhaps one in ten epileptics has insane periods, more or less,” he
+went on, “and there is no more dangerous form of insanity.
+Self-consciousness is lost, and in this state of automatism the worst
+of crimes have been committed without the subsequent knowledge of the
+patient. In that state they are no more responsible than are the actors
+in one’s dreams.”
+
+The hospital physician entered, accompanied by Craig’s messenger,
+breathless. Craig almost seized the package from his hands and broke
+the seal.
+
+“Ah—this is what I wanted,” he exclaimed, with an air of relief,
+forgetting for the time the exposition of the case that he was engaged
+in. “Here I have some anti-crotalus venine, of Drs. Flexner and
+Noguchi. Fortunately, in the city it is within easy reach.”
+
+Quickly, with the aid of the physician he injected it into Veda’s arm.
+
+“Of all substances in nature,” he remarked, still at work over the
+unfortunate woman, “none is so little known as the venom of serpents.”
+
+It was a startling idea which the sentence had raised in my mind. All
+at once I recalled the first remark of Seward Blair, in which he had
+repeated the password that had admitted us into the Red Lodge—“the
+Serpent’s Tooth.” Could it have been that she had really been bitten at
+some of the orgies by the serpent which they worshiped hideously
+hissing in its cage? I was sure that, at least until they were
+compelled, none would say anything about it. Was that the
+interpretation of the almost hypnotized look on Blair’s face?
+
+“We know next to nothing of the composition of the protein bodies in
+the venoms which have such terrific, quick physiological effects,”
+Kennedy was saying. “They have been studied, it is true, but we cannot
+really say that they are understood—or even that there are any adequate
+tests by which they can be recognized. The fact is, that snake venoms
+are about the safest of poisons for the criminal.”
+
+Kennedy had scarcely propounded this startling idea when a car was
+heard outside. The Rapports had arrived, with the officer I had sent
+after them, protesting and threatening.
+
+They quieted down a bit as they entered, and after a quick glance
+around saw who was present.
+
+Professor Rapport gave one glance at the victim lying exhausted on the
+bed, then drew back, melodramatically, and cried, “The Serpent—the mark
+of the serpent!”
+
+For a moment Kennedy gazed full in the eyes of them all.
+
+“_Was_ it a snake bite?” he asked slowly, then, turning to Mrs. Blair,
+after a quick glance, he went on rapidly, “The first thing to ascertain
+is whether the mark consists of two isolated punctures, from the
+poison-conducting teeth or fangs of the snake, which are constructed
+like a hypodermic needle.”
+
+The hospital physician had bent over her at the words, and before
+Kennedy could go on interrupted: “This was not a snake bite; it was
+more likely from an all-glass hypodermic syringe with a
+platinum-iridium needle.”
+
+Professor Rapport, priest of the Devil, advanced a step menacingly
+toward Kennedy. “Remember,” he said in a low, angry tone, “remember—you
+are pledged to keep the secrets of the Red Lodge!”
+
+Craig brushed aside the sophistry with a sentence. “I do not recognize
+any secrets that I have to keep about the meeting this afternoon to
+which you summoned the Blairs and Mrs. Langhorne, according to reports
+from the shadows I had placed on Mrs. Langhorne and Dr. Vaughn.”
+
+If there is such a thing as the evil eye, Rapport’s must have been a
+pair of them, as he realized that Kennedy had resorted to the simple
+devices of shadowing the devotees.
+
+A cry, almost a shriek, startled us. Kennedy’s encounter with Rapport
+had had an effect which none of us had considered. The step or two in
+advance which the prophet had taken had brought him into the line of
+vision of the still half-stupefied Veda lying back of Kennedy on the
+hospital cot.
+
+The mere sight of him, the sound of his voice and the mention of the
+Red Lodge had been sufficient to penetrate that stupor. She was sitting
+bolt upright, a ghastly, trembling specter. Slowly a smile seemed to
+creep over the cruel face of the mystic. Was it not a recognition of
+his hypnotic power?
+
+Kennedy turned and laid a gentle hand on the quaking convulsed figure
+of the woman. One could feel the electric tension in the air, the
+battle of two powers for good or evil. Which would win—the old
+fascination of the occult or the new power of science?
+
+It was a dramatic moment. Yet not so dramatic as the outcome. To my
+surprise, neither won.
+
+Suddenly she caught sight of her husband. Her face changed. All the
+prehistoric jealousy of which woman is capable seemed to blaze forth.
+
+“I will defend myself!” she cried. “I will fight back! She shall not
+win—she shall not have you—no—she shall not—never!”
+
+I recalled the strained feeling between the two women that I had
+noticed in the cab. Was it Mrs. Langhorne who had been the disturbing
+influence, whose power she feared, over herself and over her husband?
+
+Rapport had fallen back a step, but not from the mind of Kennedy.
+
+“Here,” challenged Craig, facing the group and drawing from his pocket
+the glass ampoule, “I picked this up at the Red Lodge last night.”
+
+He held it out in his hand before the Rapports so that they could not
+help but see it. Were they merely good actors? They betrayed nothing,
+at least by face or action.
+
+“It is crotalin,” he announced, “the venom of the rattlesnake—crotalus
+horridus. It has been noticed that persons suffering from certain
+diseases of which epilepsy is one, after having been bitten by a
+rattlesnake, if they recover from the snake bite, are cured of the
+disease.”
+
+Kennedy was forging straight ahead now in his exposure. “Crotalin,” he
+continued, “is one of the new drugs used in the treatment of epilepsy.
+But it is a powerful two-edged instrument. Some one who knew the drug,
+who perhaps had used it, has tried an artificial bite of a rattler on
+Veda Blair, not for epilepsy, but for another, diabolical purpose,
+thinking to cover up the crime, either as the result of the so-called
+death thought of the Lodge or as the bite of the real rattler at the
+Lodge.”
+
+Kennedy had at last got under Dr. Vaughn’s guard. All his reticence was
+gone.
+
+“I joined the cult,” he confessed. “I did it in order to observe and
+treat one of my patients for epilepsy. I justified myself. I said, ‘I
+will be the exposer, not the accomplice, of this modern Satanism.’ I
+joined it and—”
+
+“There is no use trying to shield anyone, Vaughn,” rapped out Kennedy,
+scarcely taking time to listen. “An epileptic of the most dangerous
+criminal type has arranged this whole elaborate setting as a plot to
+get rid of the wife who brought him his fortune and now stands in the
+way of his unholy love of Mrs. Langhorne. He used you to get the poison
+with which you treated him. He used the Rapports with money to play on
+her mysticism by their so-called death thought, while he watched his
+opportunity to inject the fatal crotalin.”
+
+Craig faced the criminal, whose eyes now showed more plainly than words
+his deranged mental condition, and in a low tone added, “The Devil _is_
+in you, Seward Blair!”
+
+
+
+
+CHAPTER XXV
+THE “HAPPY DUST”
+
+
+Veda Blair’s rescue from the strange use that was made of the venom
+came at a time when the city was aroused as it never had been before
+over the nation-wide agitation against drugs.
+
+Already, it will be recalled, Kennedy and I had had some recent
+experience with dope fiends of various kinds, but this case I set down
+because it drew us more intimately into the crusade.
+
+“I’ve called on you, Professor Kennedy, to see if I can’t interest you
+in the campaign I am planning against drugs.”
+
+Mrs. Claydon Sutphen, social leader and suffragist, had scarcely more
+than introduced herself when she launched earnestly into the reason for
+her visit to us.
+
+“You don’t realize it, perhaps,” she continued rapidly, “but very often
+a little silver bottle of tablets is as much a necessary to some women
+of the smart set as cosmetics.”
+
+“I’ve heard of such cases,” nodded Craig encouragingly.
+
+“Well, you see I became interested in the subject,” she added, “when I
+saw some of my own friends going down. That’s how I came to plan the
+campaign in the first place.”
+
+She paused, evidently nervous. “I’ve been threatened, too,” she went
+on, “but I’m not going to give up the fight. People think that drugs
+are a curse only to the underworld, but they have no idea what inroads
+the habit has made in the upper world, too. Oh, it is awful!” she
+exclaimed.
+
+Suddenly, she leaned over and whispered, “Why, there’s my own sister,
+Mrs. Garrett. She began taking drugs after an operation, and now they
+have a terrible hold on her. I needn’t try to conceal anything. It’s
+all been published in the papers—everybody knows it. Think of
+it—divorced, disgraced, all through these cursed drugs! Dr. Coleman,
+our family physician, has done everything known to break up the habit,
+but he hasn’t succeeded.”
+
+Dr. Coleman, I knew, was a famous society physician. If he had failed,
+I wondered why she thought a detective might succeed. But it was
+evidently another purpose she had in mind in introducing the subject.
+
+“So you can understand what it all means to me, personally,” she
+resumed, with a sigh. “I’ve studied the thing—I’ve been forced to study
+it. Why, now the exploiters are even making drug fiends of
+mere—children!”
+
+Mrs. Sutphen spread out a crumpled sheet of note paper before us on
+which was written something in a trembling scrawl. “For instance,
+here’s a letter I received only yesterday.”
+
+Kennedy glanced over it carefully. It was signed “A Friend,” and read:
+
+“I have heard of your drug war in the newspapers and wish to help you,
+only I don’t dare to do so openly. But I can assure you that if you
+will investigate what I am about to tell you, you will soon be on the
+trail of those higher up in this terrible drug business. There is a
+little center of the traffic on West 66th Street, just off Broadway. I
+cannot tell you more, but if you can investigate it, you will be doing
+more good than you can possibly realize now. There is one girl there,
+whom they call ‘Snowbird.’ If you could only get hold of her quietly
+and place her in a sanitarium you might save her yet.”
+
+Craig was more than ordinarily interested. “And the children—what did
+you mean by that?”
+
+“Why, it’s literally true,” asserted Mrs. Sutphen in a horrified tone.
+“Some of the victims are actually school children. Up there in 66th
+Street we have found a man named Armstrong, who seems to be very
+friendly with this young girl whom they call ‘Snowbird.’ Her real name,
+by the way, is Sawtelle, I believe. She can’t be over eighteen, a mere
+child, yet she’s a slave to the stuff.”
+
+“Oh, then you have actually already acted on the hint in the letter?”
+asked Craig.
+
+“Yes,” she replied, “I’ve had one of the agents of our Anti-Drug
+Society, a social worker, investigating the neighborhood.”
+
+Kennedy nodded for her to go on.
+
+“I’ve even investigated myself a little, and now I want to employ some
+one to break the thing up. My husband had heard of you and so here I
+am. Can you help me?”
+
+There was a note of appeal in her voice that was irresistible to a man
+who had the heart of Kennedy.
+
+“Tell me just what you have discovered so far,” he asked simply.
+
+“Well,” she replied slowly, “after my agent verified the contents of
+the letter, I watched until I saw this girl—she’s a mere child, as I
+said—going to a cabaret in the neighborhood. What struck me was that I
+saw her go in looking like a wreck and come out a beautiful creature,
+with bright eyes, flushed cheeks, almost youthful again. A most
+remarkable girl she is, too,” mused Mrs. Sutphen, “who always wears a
+white gown, white hat, white shoes and white stockings. It must be a
+mania with her.”
+
+Mrs. Sutphen seemed to have exhausted her small store of information,
+and as she rose to go Kennedy rose also. “I shall be glad to look into
+the case, Mrs. Sutphen,” he promised. “I’m sure there is something that
+can be done—there must be.”
+
+“Thank you, ever so much,” she murmured, as she paused at the door,
+something still on her mind. “And perhaps, too,” she added, “you may
+run across my sister, Mrs. Garrett.”
+
+“Indeed,” he assured her, “if there is anything I can possibly do that
+will assist you personally, I shall be only too happy to do it.”
+
+“Thank you again, ever so much,” she repeated with just a little choke
+in her voice.
+
+For several moments Kennedy sat contemplating the anonymous letter
+which she had left with him, studying both its contents and the
+handwriting.
+
+“We must go over the ground up there again,” he remarked finally.
+“Perhaps we can do better than Mrs. Sutphen and her drug investigator
+have done.”
+
+Half an hour later we had arrived and were sauntering along the street
+in question, walking slowly up and down in the now fast-gathering dusk.
+It was a typical cheap apartment block of variegated character, with
+people sitting idly on the narrow front steps and children spilling out
+into the roadway in imminent danger of their young lives from every
+passing automobile.
+
+On the crowded sidewalk a creation in white hurtled past us. One glance
+at the tense face in the flickering arc light was enough for Kennedy.
+He pulled my arm and we turned and followed at a safe distance.
+
+She looked like a girl who could not have been more than eighteen, if
+she was as old as that. She was pretty, too, but already her face was
+beginning to look old and worn from the use of drugs. It was
+unmistakable.
+
+In spite of the fact that she was hurrying, it was not difficult to
+follow her in the crowd, as she picked her way in and out, and finally
+turned into Broadway where the white lights were welcoming the night.
+
+Under the glare of a huge electric sign she stopped a moment, then
+entered one of the most notorious of the cabarets.
+
+We entered also at a discreet distance and sat down at a table.
+
+“Don’t look around, Walter,” whispered Craig, as the waiter took our
+order, “but to your right is Mrs. Sutphen.”
+
+If he had mentioned any other name in the world, I could not have been
+more surprised. I waited impatiently until I could pick her out from
+the corner of my eye. Sure enough, it was Mrs. Sutphen and another
+woman. What they were doing there I could not imagine, for neither had
+the look of habitues of such a place.
+
+I followed Kennedy’s eye and found that he was gazing furtively at a
+flashily dressed young man who was sitting alone at the far end in a
+sort of booth upholstered in leather.
+
+The girl in white, whom I was now sure was Miss Sawtelle, went over and
+greeted him. It was too far to see just what happened, but the young
+woman after sitting down rose and left almost immediately. As nearly as
+I could make out, she had got something from him which she had dropped
+into her handbag and was now hugging the handbag close to herself
+almost as if it were gold.
+
+We sat for a few minutes debating just what to do, when Mrs. Sutphen
+and her friend rose. As she passed out, a quick, covert glance told us
+to follow. We did so and the two turned into Broadway.
+
+“Let me present you to Miss McCann,” introduced Mrs. Sutphen as we
+caught up with them. “Miss McCann is a social worker and trained
+investigator whom I’m employing.”
+
+We bowed, but before we could ask a question, Mrs. Sutphen cried
+excitedly: “I think I have a clue, anyway. We’ve traced the source of
+the drugs at least as far as that young fellow, ‘Whitecap,’ whom you
+saw in there.”
+
+I had not recognized his face, although I had undoubtedly seen pictures
+of him before. But no sooner had I heard the name than I recognized it
+as that of one of the most notorious gang leaders on the West Side.
+
+Not only that, but Whitecap’s gang played an important part in local
+politics. There was scarcely a form of crime or vice to which Whitecap
+and his followers could not turn a skilled hand, whether it was
+swinging an election, running a gambling club, or dispensing “dope.”
+
+“You see,” she explained, “even before I saw you, my suspicions were
+aroused and I determined to obtain some of the stuff they are using up
+here, if possible. I realized it would be useless for me to try to get
+it myself, so I got Miss McCann from the Neighborhood House to try it.
+She got it and has turned the bottle over to me.”
+
+“May I see it?” asked Craig eagerly.
+
+Mrs. Sutphen reached hastily into her handbag, drew forth a small brown
+glass bottle and handed it to him. Craig retreated into one of the less
+dark side streets. There he pulled out the paraffinned cork from the
+bottle, picked out a piece of cotton stuffed in the neck of the bottle
+and poured out some flat tablets that showed a glistening white in the
+palm of his hand. For an instant he regarded them.
+
+“I may keep these?” he asked.
+
+“Certainly,” replied Mrs. Sutphen. “That’s what I had Miss McCann get
+them for.”
+
+Kennedy dropped the bottle into his pocket.
+
+“So that was the gang leader, ‘Whitecap,’” he remarked as we turned
+again to Broadway.
+
+“Yes,” replied Mrs. Sutphen. “At certain hours, I believe he can be
+found at that cabaret selling this stuff, whatever it is, to anyone who
+comes properly introduced. The thing seems to be so open and notorious
+that it amounts to a scandal.”
+
+We parted a moment later, Mrs. Sutphen and Miss McCann to go to the
+settlement house, Craig and I to continue our investigations.
+
+“First of all, Walter,” he said as we swung aboard an uptown car, “I
+want to stop at the laboratory.”
+
+In his den, which had been the scene of so many triumphs, Kennedy began
+a hasty examination of the tablets, powdering one and testing it with
+one chemical after another.
+
+“What are they?” I asked at length when he seemed to have found the
+right reaction which gave him the clue.
+
+“Happy dust,” he answered briefly.
+
+“Happy dust?” I repeated, looking at him a moment in doubt as to
+whether he was joking or serious. “What is that?”
+
+“The Tenderloin name for heroin—a comparatively new derivative of
+morphine. It is really morphine treated with acetic acid which renders
+it more powerful than morphine alone.”
+
+“How do they take them? What’s the effect?” I asked.
+
+“The person who uses heroin usually powders the tablets and snuffs the
+powder up the nose,” he answered. “In a short time, perhaps only two or
+three weeks, one can become a confirmed victim of ‘happy dust.’ And
+while one is under its influence he is morally, physically and mentally
+irresponsible.”
+
+Kennedy was putting away the paraphernalia he had used, meanwhile
+talking about the drug. “One of the worst aspects of it, too,” he
+continued, “is the desire of the user to share his experience with some
+one else. This passing on of the habit, which seems to be one of the
+strongest desires of the drug fiend, makes him even more dangerous to
+society than he would otherwise be. It makes it harder for anyone once
+addicted to a drug to shake it off, for his friends will give him no
+chance. The only thing to do is to get the victim out of his
+environment and into an entirely new scene.”
+
+The laboratory table cleared again, Kennedy had dropped into a deep
+study.
+
+“Now, why was Mrs. Sutphen there?” he asked aloud. “I can’t think it
+was solely through her interest for that girl they call Snowbird. She
+was interested in her, but she made no attempt to interfere or to
+follow her. No, there must have been another reason.”
+
+“You don’t think she’s a dope fiend herself, do you?” I asked
+hurriedly.
+
+Kennedy smiled. “Hardly, Walter. If she has any obsession on the
+subject, it is more likely to lead her to actual fanaticism against all
+stimulants and narcotics and everything connected with them. No, you
+might possibly persuade me that two and two equal five—but not
+seventeen. It’s not very late. I think we might make another visit to
+that cabaret and see whether the same thing is going on yet.”
+
+
+
+
+CHAPTER XXVI
+THE BINET TEST
+
+
+We rode downtown again and again sauntered in, this time with the
+theater crowd. Our first visit had been so quiet and unostentatious
+that the second attracted no attention or comment from the waiters, or
+anyone else.
+
+As we sat down we glanced over, and there in his corner still was
+Whitecap. Apparently his supply of the dope was inexhaustible, for he
+was still dispensing it. As we watched the tenderloin habitues come and
+go, I came soon to recognize the signs by the mere look on the face—the
+pasty skin, the vacant eye, the nervous quiver of the muscles as though
+every organ and every nerve were crying out for more of the favorite
+nepenthe. Time and again I noticed the victims as they sat at the
+tables, growing more and more haggard and worn, until they could stand
+it no longer. Then they would retire, sometimes after a visit across
+the floor to Whitecap, more often directly, for they had stocked
+themselves up with the drug evidently after the first visit to him. But
+always they would come back, changed in appearance, with what seemed to
+be a new lease of life, but nevertheless still as recognizable as drug
+victims.
+
+It was not long, as we waited, before another woman, older than Miss
+Sawtelle, but dressed in an extreme fashion, hurried into the cabaret
+and with scarcely a look to right or left went directly to Whitecap’s
+corner. I noticed that she, too, had the look.
+
+There was a surreptitious passing of a bottle in exchange for a
+treasury note, and she dropped into the seat beside him.
+
+Before he could interfere, she had opened the bottle, crushed a tablet
+or two in a napkin, and was holding it to her face as though breathing
+the most exquisite perfume. With one quick inspiration of her breath
+after another, she was snuffing the powder up her nose.
+
+Whitecap with an angry gesture pulled the napkin from her face, and one
+could fancy his snarl under his breath, “Say—do you want to get me in
+wrong here?”
+
+But it was too late. Some at least of the happy dust had taken effect,
+at least enough to relieve the terrible pangs she must have been
+suffering.
+
+As she rose and retired, with a hasty apology to Whitecap for her
+indiscretion, Kennedy turned to me and exclaimed, “Think of it. The
+deadliest of all habits is the simplest. No hypodermic; no pipe; no
+paraphernalia of any kind. It’s terrible.”
+
+She returned to sit down and enjoy herself, careful not to obtrude
+herself on Whitecap lest he might become angry at the mere sight of her
+and treasure his anger up against the next time when she would need the
+drug.
+
+Already there was the most marvelous change in her. She seemed
+captivated by the music, the dancing, the life which a few moments
+before she had totally disregarded.
+
+She was seated alone, not far from us, and as she glanced about Kennedy
+caught her eye. She allowed her gaze to rest on us for a moment, the
+signal for a mild flirtation which ended in our exchange of tables and
+we found ourselves opposite the drug fiend, who was following up the
+taking of the dope by a thin-stemmed glass of a liqueur.
+
+I do not recall the conversation, but it was one of those
+inconsequential talks that Bohemians consider so brilliant and
+everybody else so vapid. As we skimmed from one subject to another,
+treating the big facts of life as if they were mere incidents and the
+little as if they overshadowed all else, I could see that Craig, who
+had a faculty of probing into the very soul of anyone, when he chose,
+was gradually leading around to a subject which I knew he wanted, above
+all others, to discuss.
+
+It was not long before, as the most natural remark in the world
+following something he had made her say, just as a clever
+prestidigitator forces a card, he asked, “What was it I saw you
+snuffing over in the booth—happy dust?”
+
+She did not even take the trouble to deny it, but nodded a brazen
+“Yes.” “How did you come to use it first?” he asked, careful not to
+give offense in either tone or manner.
+
+“The usual way, I suppose,” she replied with a laugh that sounded harsh
+and grating. “I was ill and I found out what it was the doctor was
+giving me.”
+
+“And then?”
+
+“Oh, I thought I would use it only as long as it served my purpose and,
+when that was over, give it up.”
+
+“But—?” prompted Craig hypnotically.
+
+“Instead, I was soon using six, eight, ten tablets of heroin a day. I
+found that I needed that amount in order to live. Then it went up by
+leaps to twenty, thirty, forty.”
+
+“Suppose you couldn’t get it, what then?”
+
+“Couldn’t get it?” she repeated with an unspeakable horror. “Once I
+thought I’d try to stop. But my heart skipped beats; then it seemed to
+pound away, as if trying to break through my ribs. I don’t think heroin
+is like other drugs. When one has her ‘coke’—that’s cocaine—taken away,
+she feels like a rag. Fill her up and she can do anything again. But,
+heroin—I think one might murder to get it!”
+
+The expression on the woman’s face was almost tragic. I verily believe
+that she meant it.
+
+“Why,” she cried, “if anyone had told me a year ago that the time would
+ever come when I would value some tiny white tablets above anything
+else in the world, yes, and even above my immortal soul, I would have
+thought him a lunatic.”
+
+It was getting late, and as the woman showed no disposition to leave,
+Kennedy and I excused ourselves.
+
+Outside Craig looked at me keenly. “Can you guess who that was?”
+
+“Although she didn’t tell us her name,” I replied, “I am morally
+certain that it was Mrs. Garrett.”
+
+“Precisely,” he answered, “and what a shame, too, for she must
+evidently once have been a woman of great education and refinement.”
+
+He shook his head sadly. “Walter, there isn’t likely to be anything
+that we can do for some hours now. I have a little experiment I’d like
+to make. Suppose you publish for me a story in the _Star_ about the
+campaign against drugs. Tell about what we have seen to-night, mention
+the cabaret by indirection and Whitecap directly. Then we can sit back
+and see what happens. We’ve got to throw a scare into them somehow, if
+we are going to smoke out anyone higher up than Whitecap. But you’ll
+have to be careful, for if they suspect us our usefulness in the case
+will be over.”
+
+Together, Kennedy and I worked over our story far into the night down
+at the _Star_ office, and the following day waited to see whether
+anything came of it.
+
+It was with a great deal of interest tempered by fear that we dropped
+into the cabaret the following evening. Fortunately no one suspected
+us. In fact, having been there the night before, we had established
+ourselves, as it were, and were welcomed as old patrons and good
+spenders.
+
+I noticed, however, that Whitecap was not there. The story had been
+read by such of the dope fiends as had not fallen too far to keep
+abreast of the times and these and the waiters were busy quietly
+warning off a line of haggard-eyed, disappointed patrons who came
+around, as usual.
+
+Some of them were so obviously dependent on Whitecap that I almost
+regretted having written the story, for they must have been suffering
+the tortures of the damned.
+
+It was in the midst of a reverie of this sort that a low exclamation
+from Kennedy recalled my attention. There was Snowbird with a man
+considerably older than herself. They had just come in and were looking
+about frantically for Whitecap. But Whitecap had been too frightened by
+the story in the _Star_ to sell any more of the magic happy dust openly
+in the cabaret, at least.
+
+The pair, nerve-racked and exhausted, sat down mournfully in a seat
+near us, and as they talked earnestly in low tones we had an excellent
+opportunity for studying Armstrong for the first time.
+
+He was not a bad-looking man, or even a weak one. In back of the
+dissipation of the drugs one fancied he could read the story of a
+brilliant life wrecked. But there was little left to admire or respect.
+As the couple talked earnestly, the one so old, the other so young in
+vice, I had to keep a tight rein on myself to prevent my sympathy for
+the wretched girl getting the better of common sense and kicking the
+older man out of doors.
+
+Finally Armstrong rose to go, with a final imploring glance from the
+girl. Obviously she had persuaded him to forage about to secure the
+heroin, by hook or crook, now that the accustomed source of supply was
+cut off so suddenly.
+
+It was also really our first chance to study the girl carefully under
+the light, for her entrance and exit the night before had been so
+hurried that we had seen comparatively little of her. Craig was
+watching her narrowly. Not only were the effects of the drug plainly
+evident on her face, but it was apparent that the snuffing the powdered
+tablets was destroying the bones in her nose, through shrinkage of the
+blood vessels, as well as undermining the nervous system and causing
+the brain to totter.
+
+I was wondering whether Armstrong knew of any depot for the secret
+distribution of the drug. I could not believe that Whitecap was either
+the chief distributer or the financial head of the illegal traffic. I
+wondered who indeed was the man higher up. Was he an importer of the
+drug, or was he the representative of some chemical company not averse
+to making an illegal dollar now and then by dragging down his fellow
+man?
+
+Kennedy and I were trying to act as if we were enjoying the cabaret
+show and not too much interested in the little drama that was being
+acted before us. I think little Miss Sawtelle noticed, however, that we
+were looking often her way. I was amazed, too, on studying her more
+closely to find that there was something indefinably queer about her,
+aside from the marked effect of the drugs she had been taking. What it
+was I was at a loss to determine, but I felt sure from the expression
+on Kennedy’s face that he had noticed it also.
+
+I was on the point of asking him if he, too, observed anything queer in
+the girl, when Armstrong hurried in and handed her a small package,
+then almost without a word stalked out again, evidently as much to
+Snowbird’s surprise as to our own.
+
+She had literally seized the package, as though she were drowning and
+grasping at a life buoy. Even the surprise at his hasty departure could
+not prevent her, however, from literally tearing the wrapper off, and
+in the sheltering shadow of the table cloth pouring forth the little
+white pellets in her lap, counting them as a miser counts his gold,
+
+“The old thief!” she exclaimed aloud. “He’s held out twenty-five!”
+
+I don’t know which it was that amazed me most, the almost childish
+petulance and ungovernable temper of the girl which made her cry out in
+spite of her surroundings and the circumstances, or the petty rapacity
+of the man who could stoop to such a low level as to rob her in this
+seeming underhand manner.
+
+There was no time for useless repining now. The call of outraged nature
+for its daily and hourly quota of poison was too imperative. She dumped
+the pellets back into the bottle hastily, and disappeared.
+
+When she came back, it was with that expression I had come to know so
+well. At least for a few hours there was a respite for her from the
+terrific pangs she had been suffering. She was almost happy, smiling.
+Even that false happiness, I felt, was superior to Armstrong’s moral
+sense blunted by drugs. I had begun to realize how lying, stealing,
+crimes of all sorts might be laid at the door of this great evil.
+
+In her haste to get where she could snuff the heroin she had forgotten
+a light wrap lying on her chair. As she returned for it, it fell to the
+floor. Instantly Kennedy was on his feet, bending over to pick it up.
+
+She thanked him, and the smile lingered a moment on her face. It was
+enough. It gave Kennedy the chance to pursue a conversation, and in the
+free and easy atmosphere of the cabaret to invite her to sit over at
+our table.
+
+At least all her nervousness was gone and she chatted vivaciously.
+Kennedy said little. He was too busy watching her. It was quite the
+opposite of the case of Mrs. Garrett. Yet I was at a loss to define
+what it was that I sensed.
+
+Still the minutes sped past and we seemed to be getting on famously.
+Unlike his action in the case of the older woman where he had been
+sounding the depths of her heart and mind, in this case his idea seemed
+to be to allow the childish prattle to come out and perhaps explain
+itself.
+
+However, at the end of half an hour when we seemed to be getting no
+further along, Kennedy did not protest at her desire to leave us, “to
+keep a date,” as she expressed it.
+
+“Waiter, the check, please,” ordered Kennedy leisurely.
+
+When he received it, he seemed to be in no great hurry to pay it, but
+went over one item after another, then added up the footing again.
+
+“Strange how some of these waiters grow rich?” Craig remarked finally
+with a gay smile.
+
+The idea of waiters and money quickly brought some petty reminiscences
+to her mind. While she was still talking, Craig casually pulled a
+pencil out of his pocket and scribbled some figures on the back of the
+waiter’s check.
+
+From where I was sitting beside him, I could see that he had written
+some figures similar to the following:
+
+5183
+47395
+654726
+2964375
+47293815
+924738651
+2146073859
+
+
+“Here’s a stunt,” he remarked, breaking into the conversation at a
+convenient point. “Can you repeat these numbers after me?”
+
+Without waiting for her to make excuse, he said quickly “5183.” “5183,”
+she repeated mechanically.
+
+“47395,” came in rapid succession, to which she replied, perhaps a
+little slower than before,
+
+“47395.”
+
+“Now, 654726,” he said.
+
+“654726,” she repeated, I thought with some hesitation.
+
+“Again, 2964375,” he shot out.
+
+“269,” she hesitated, “73—” she stopped.
+
+It was evident that she had reached the limit.
+
+Kennedy smiled, paid the check and we parted at the door.
+
+“What was all that rigmarole?” I inquired as the white figure
+disappeared down the street.
+
+“Part of the Binet test, seeing how many digits one can remember. An
+adult ought to remember from eight to ten, in any order. But she has
+the mentality of a child. That is the queer thing about her.
+Chronologically she may be eighteen years or so old. Mentally she is
+scarcely more than eight. Mrs. Sutphen was right. They have made a
+fiend out of a mere child—a defective who never had a chance against
+them.”
+
+
+
+
+CHAPTER XXVII
+THE LIE DETECTOR
+
+
+As the horror of it all dawned on me, I hated Armstrong worse than
+ever, hated Whitecap, hated the man higher up, whoever he might be, who
+was enriching himself out of the defective, as well as the weakling,
+and the vicious—all three typified by Snowbird, Armstrong and Whitecap.
+
+Having no other place to go, pending further developments of the
+publicity we had given the drug war in the _Star_, Kennedy and I
+decided on a walk home in the bracing night air.
+
+We had scarcely entered the apartment when the hall boy called to us
+frantically: “Some one’s been trying to get you all over town,
+Professor Kennedy. Here’s the message. I wrote it down. An attempt has
+been made to poison Mrs. Sutphen. They said at the other end of the
+line that you’d know.”
+
+We faced each other aghast.
+
+“My God!” exclaimed Kennedy. “Has that been the effect of our story,
+Walter? Instead of smoking out anyone—we’ve almost killed some one.”
+
+As fast as a cab could whisk us around to Mrs. Sutphen’s we hurried.
+
+“I warned her that if she mixed up in any such fight as this she might
+expect almost anything,” remarked Mr. Sutphen nervously, as he met us
+in the reception room. “She’s all right, now, I guess, but if it hadn’t
+been for the prompt work of the ambulance surgeon I sent for, Dr.
+Coleman says she would have died in fifteen minutes.”
+
+“How did it happen?” asked Craig.
+
+“Why, she usually drinks a glass of vichy and milk before retiring,”
+replied Mr. Sutphen. “We don’t know yet whether it was the vichy or the
+milk that was poisoned, but Dr. Coleman thinks it was chloral in one or
+the other, and so did the ambulance surgeon. I tell you I was scared. I
+tried to get Coleman, but he was out on a case, and I happened to think
+of the hospitals as probably the quickest. Dr. Coleman came in just as
+the young surgeon was bringing her around. He—oh, here he is now.”
+
+The famous doctor was just coming downstairs. He saw us, but, I
+suppose, inasmuch as we did not belong to the Sutphen and Coleman set,
+ignored us. “Mrs. Sutphen will be all right now,” he said reassuringly
+as he drew on his gloves. “The nurse has arrived, and I have given her
+instructions what to do. And, by the way, my dear Sutphen, I should
+advise you to deal firmly with her in that matter about which her name
+is appearing in the papers. Women nowadays don’t seem to realize the
+dangers they run in mixing in in all these reforms. I have ordered an
+analysis of both the milk and vichy, but that will do little good
+unless we can find out who poisoned it. And there are so many chances
+for things like that, life is so complex nowadays—”
+
+He passed out with scarcely a nod at us. Kennedy did not attempt to
+question him. He was thinking rapidly.
+
+“Walter, we have no time to lose,” he exclaimed, seizing a telephone
+that stood on a stand near by. “This is the time for action.
+Hello—Police Headquarters, First Deputy O’Connor, please.”
+
+As Kennedy waited I tried to figure out how it could have happened. I
+wondered whether it might not have been Mrs. Garrett. Would she stop at
+anything if she feared the loss of her favorite drug? But then there
+were so many others and so many ways of “getting” anybody who
+interfered with the drug traffic that it seemed impossible to figure it
+out by pure deduction.
+
+“Hello, O’Connor,” I heard Kennedy say; “you read that story in the
+_Star_ this morning about the drug fiends at that Broadway cabaret?
+Yes? Well, Jameson and I wrote it. It’s part of the drug war that Mrs.
+Sutphen has been waging. O’Connor, she’s been poisoned—oh, no—she’s all
+right now. But I want you to send out and arrest Whitecap and that
+fellow Armstrong immediately. I’m going to put them through a
+scientific third degree up in the laboratory to-night. Thank you. No—no
+matter how late it is, bring them up.”
+
+Dr. Coleman had gone long since, Mr. Sutphen had absolutely no interest
+further than the recovery of Mrs. Sutphen just now, and Mrs. Sutphen
+was resting quietly and could not be seen. Accordingly Kennedy and I
+hastened up to the laboratory to wait until O’Connor could “deliver the
+goods.”
+
+It was not long before one of O’Connor’s men came in with Whitecap.
+
+“While we’re waiting,” said Craig, “I wish you would just try this
+little cut-out puzzle.”
+
+I don’t know what Whitecap thought, but I know I looked at Craig’s
+invitation to “play blocks” as a joke scarcely higher in order than the
+number repetition of Snowbird. Whitecap did it, however, sullenly, and
+under compulsion, in, I should say about two minutes.
+
+“I have Armstrong here myself,” called out the voice of our old friend
+O’Connor, as he burst into the room.
+
+“Good!” exclaimed Kennedy. “I shall be ready for him in just a second.
+Have Whitecap held here in the anteroom while you bring Armstrong into
+the laboratory. By the way, Walter, that was another of the Binet
+tests, putting a man at solving puzzles. It involves reflective
+judgment, one of the factors in executive ability. If Whitecap had been
+defective, it would have taken him five minutes to do that puzzle, if
+at all. So you see he is not in the class with Miss Sawtelle. The test
+shows him to be shrewd. He doesn’t even touch his own dope. Now for
+Armstrong.”
+
+I knew enough of the underworld to set Whitecap down, however, as a
+“lobbygow”—an agent for some one higher up, recruiting both the gangs
+and the ranks of street women.
+
+Before us, as O’Connor led in Armstrong, was a little machine with a
+big black cylinder. By means of wires and electrodes Kennedy attached
+it to Armstrong’s chest.
+
+“Now, Armstrong,” he began in an even tone, “I want you to tell the
+truth—the whole truth. You have been getting heroin tablets from
+Whitecap.”
+
+“Yes, sir,” replied the dope fiend defiantly.
+
+“To-day you had to get them elsewhere.”
+
+No answer.
+
+“Never mind,” persisted Kennedy, still calm, “I know. Why, Armstrong,
+you even robbed that girl of twenty-five tablets.”
+
+“I did not,” shot out the answer.
+
+“There were twenty-five short,” accused Kennedy.
+
+The two faced each other. Craig repeated his remark.
+
+“Yes,” replied Armstrong, “I held out the tablets, but it was not for
+myself, I can get all I want. I did it because I didn’t want her to get
+above seventy-five a day. I have tried every way to break her of the
+habit that has got me—and failed. But seventy-five—is the limit!”
+
+“A pretty story!” exclaimed O’Connor.
+
+Craig laid his hand on his arm to check him, as he examined a record
+registered on the cylinder of the machine.
+
+“By the way, Armstrong, I want you to write me out a note that I can
+use to get a hundred heroin tablets. You can write it all but the name
+of the place where I can get them.”
+
+Armstrong was on the point of demurring, but the last sentence
+reassured him. He would reveal nothing by it—yet.
+
+Still the man was trembling like a leaf. He wrote:
+
+“Give Whitecap one hundred shocks—A Victim.”
+
+For a moment Kennedy studied the note carefully. “Oh—er—I forgot,
+Armstrong, but a few days ago an anonymous letter was sent to Mrs.
+Sutphen, signed ‘A Friend.’ Do you know anything about it?”
+
+“A note?” the man repeated. “Mrs. Sutphen? I don’t know anything about
+any note, or Mrs. Sutphen either.”
+
+Kennedy was still studying his record. “This,” he remarked slowly, “is
+what I call my psychophysical test for falsehood. Lying, when it is
+practiced by an expert, is not easily detected by the most careful
+scrutiny of the liar’s appearance and manner.
+
+“However, successful means have been developed for the detection of
+falsehood by the study of experimental psychology. Walter, I think you
+will recall the test I used once, the psychophysical factor of the
+character and rapidity of the mental process known as the association
+of ideas?”
+
+I nodded acquiescence.
+
+“Well,” he resumed, “in criminal jurisprudence, I find an even more
+simple and more subjective test which has been recently devised.
+Professor Stoerring of Bonn has found out that feelings of pleasure and
+pain produce well-defined changes in respiration. Similar effects are
+produced by lying, according to the famous Professor Benussi of Graz.
+
+“These effects are unerring, unequivocal. The utterance of a false
+statement increases respiration; of a true statement decreases. The
+importance and scope of these discoveries are obvious.”
+
+Craig was figuring rapidly on a piece of paper. “This is a certain and
+objective criterion,” he continued as he figured, “between truth and
+falsehood. Even when a clever liar endeavors to escape detection by
+breathing irregularly, it is likely to fail, for Benussi has
+investigated and found that voluntary changes in respiration don’t
+alter the result. You see, the quotient obtained by dividing the time
+of inspiration by the time of expiration gives me the result.”
+
+He looked up suddenly. “Armstrong, you are telling the truth about some
+things—downright lies about others. You are a drug fiend—but I will be
+lenient with you, for one reason. Contrary to everything that I would
+have expected, you are really trying to save that poor half-witted girl
+whom you love from the terrible habit that has gripped you. That is why
+you held out the quarter of the one hundred tablets. That is why you
+wrote the note to Mrs. Sutphen, hoping that she might be treated in
+some institution.”
+
+Kennedy paused as a look of incredulity passed over Armstrong’s face.
+
+“Another thing you said was true,” added Kennedy. “You can get all the
+heroin you want. Armstrong, you will put the address of that place on
+the outside of the note, or both you and Whitecap go to jail. Snowbird
+will be left to her own devices—she can get all the ‘snow,’ as some of
+you fiends call it, that she wants from those who might exploit her.”
+
+“Please, Mr. Kennedy,” pleaded Armstrong.
+
+“No,” interrupted Craig, before the drug fiend could finish. “That is
+final. I must have the name of that place.”
+
+In a shaky hand Armstrong wrote again. Hastily Craig stuffed the note
+into his pocket, and ten minutes later we were mounting the steps of a
+big brownstone house on a fashionable side street just around the
+corner from Fifth Avenue.
+
+As the door was opened by an obsequious colored servant, Craig handed
+him the scrap of paper signed by the password, “A Victim.”
+
+Imitating the cough of a confirmed dope user, Craig was led into a
+large waiting room.
+
+“You’re in pretty bad shape, sah,” commented the servant.
+
+Kennedy nudged me and, taking the cue, I coughed myself red in the
+face.
+
+“Yes,” he said. “Hurry—please.”
+
+The servant knocked at a door, and as it was opened we caught a glimpse
+of Mrs. Garrett in negligee.
+
+“What is it, Sam?” she asked.
+
+“Two gentlemen for some heroin tablets, ma’am.”
+
+“Tell them to go to the chemical works—not to my office, Sam,” growled
+a man’s voice inside.
+
+With a quick motion, Kennedy had Mrs. Garrett by the wrist.
+
+“I knew it,” he ground out. “It was all a fake about how you got the
+habit. You wanted to get it, so you could get and hold him. And neither
+one of you would stop at anything, not even the murder of your sister,
+to prevent the ruin of the devilish business you have built up in
+manufacturing and marketing the stuff.”
+
+He pulled the note from the hand of the surprised negro. “I had the
+right address, the place where you sell hundreds of ounces of the stuff
+a week—but I preferred to come to the doctor’s office where I could
+find you both.”
+
+Kennedy had firmly twisted her wrist until, with a little scream of
+pain, she let go the door handle. Then he gently pushed her aside, and
+the next instant Craig had his hand inside the collar of Dr. Coleman,
+society physician, proprietor of the Coleman Chemical Works downtown,
+the real leader of the drug gang that was debauching whole sections of
+the metropolis.
+
+
+
+
+CHAPTER XXVIII
+THE FAMILY SKELETON
+
+
+Surprised though we were at the unmasking of Dr. Coleman, there was
+nothing to do but to follow the thing out. In such cases we usually ran
+into the greatest difficulty—organized vice. This was no exception.
+
+Even when cases involved only a clever individual or a prominent
+family, it was the same. I recall, for example, the case of a
+well-known family in a New York suburb, which was particularly
+difficult. It began in a rather unusual manner, too.
+
+“Mr. Kennedy—I am ruined—ruined.”
+
+It was early one morning that the telephone rang and I answered it. A
+very excited German, breathless and incoherent, was evidently at the
+other end of the wire.
+
+I handed the receiver to Craig and picked up the morning paper lying on
+the table.
+
+“Minturn—dead?” I heard Craig exclaim. “In the paper this morning? I’ll
+be down to see you directly.”
+
+Kennedy almost tore the paper from me. In the next to the end column
+where late news usually is dropped was a brief account of the sudden
+death of Owen Minturn, one of the foremost criminal lawyers of the
+city, in Josephson’s Baths downtown.
+
+It ended: “It is believed by the coroner that Mr. Minturn was shocked
+to death and evidence is being sought to show that two hundred and
+forty volts of electricity had been thrown into the attorney’s body
+while he was in the electric bath. Joseph Josephson, the proprietor of
+the bath, who operated the switchboard, is being held, pending the
+completion of the inquiry.”
+
+As Kennedy hastily ran his eye over the paragraphs, he became more and
+more excited himself.
+
+“Walter,” he cried, as he finished, “I don’t believe that that was an
+accident at all.”
+
+“Why?” I asked.
+
+He already had his hat on, and I knew he was going to Josephson’s
+breakfastless. I followed reluctantly.
+
+“Because,” he answered, as we hustled along in the early morning crowd,
+“it was only yesterday afternoon that I saw Minturn at his office and
+he made an appointment with me for this very morning. He was a very
+secretive man, but he did tell me this much, that he feared his life
+was in danger and that it was in some way connected with that Pearcy
+case up in Stratfield, Connecticut, where he has an estate. You have
+read of the case?”
+
+Indeed I had. It had seemed to me to be a particularly inexplicable
+affair. Apparently a whole family had been poisoned and a few days
+before old Mr. Randall Pearcy, a retired manufacturer, had died after a
+brief but mysterious illness.
+
+Pearcy had been married a year or so ago to Annette Oakleigh, a
+Broadway comic opera singer, who was his second wife. By his first
+marriage he had had two children, a son, Warner, and a daughter,
+Isabel.
+
+Warner Pearcy, I had heard, had blazed a vermilion trail along the
+Great White Way, but his sister was of the opposite temperament,
+interested in social work, and had attracted much attention by
+organizing a settlement in the slums of Stratfield for the uplift of
+the workers in the Pearcy and other mills.
+
+Broadway, as well as Stratfield, had already woven a fantastic
+background, for the mystery and hints had been broadly made that
+Annette Oakleigh had been indiscreetly intimate with a young physician
+in the town, a Dr. Gunther, a friend, by the way, of Minturn. “There
+has been no trial yet,” went on Kennedy, “but Minturn seems to have
+appeared before the coroner’s jury at Stratfield and to have asserted
+the innocence of Mrs. Pearcy and that of Dr. Gunther so well that,
+although the jury brought in a verdict of murder by poison by some one
+unknown, there has been no mention of the name of anyone else. The
+coroner simply adjourned the inquest so that a more careful analysis
+might be made of the vital organs. And now comes this second tragedy in
+New York.”
+
+“What was the poison?” I asked. “Have they found out yet?”
+
+“They are pretty sure, so Minturn told me, that it was lead poisoning.
+The fact not generally known is,” he added in a lower tone, “that the
+cases were not confined to the Pearcy house. They had even extended to
+Minturn’s too, although about that he said little yesterday. The
+estates up there adjoin, you know.”
+
+Owen Minturn, I recalled, had gained a formidable reputation by his
+successful handling of cases from the lowest strata of society to the
+highest. Indeed it was a byword that his appearance in court indicated
+two things—the guilt of the accused and a verdict of acquittal.
+
+“Of course,” Craig pursued as we were jolted from station to station
+downtown, “you know they say that Minturn never kept a record of a
+case. But written records were as nothing compared to what that man
+must have carried only in his head.”
+
+It was a common saying that, if Minturn should tell all he knew, he
+might hang half a dozen prominent men in society. That was not strictly
+true, perhaps, but it was certain that a revelation of the things
+confided to him by clients which were never put down on paper would
+have caused a series of explosions that would have wrecked at least
+some portions of the social and financial world. He had heard much and
+told little, for he had been a sort of “father confessor.”
+
+Had Minturn, I wondered, known the name of the real criminal?
+
+Josephson’s was a popular bath on Forty-second Street, where many of
+the “sun-dodgers” were accustomed to recuperate during the day from
+their arduous pursuit of pleasure at night and prepare for the
+resumption of their toil during the coming night. It was more than
+that, however, for it had a reputation for being conducted really on a
+high plane.
+
+We met Josephson downstairs. He had been released under bail, though
+the place was temporarily closed and watched over by the agents of the
+coroner and the police. Josephson appeared to be a man of some
+education and quite different from what I had imagined from hearing him
+over the telephone.
+
+“Oh, Mr. Kennedy,” he exclaimed, “who now will come to my baths? Last
+night they were crowded, but to-day—”
+
+He ended with an expressive gesture of his hands.
+
+“One customer I have surely lost, young Mr. Pearcy,” he went on.
+
+“Warner Pearcy?” asked Craig. “Was he here last night?”
+
+“Nearly every night,” replied Josephson, now glib enough as his first
+excitement subsided and his command of English returned. “He was a
+neighbor of Mr. Minturn’s, I hear. Oh, what luck!” growled Josephson as
+the name recalled him to his present troubles.
+
+“Well,” remarked Kennedy with an attempt at reassurance as if to gain
+the masseur’s confidence, “I know as well as you that it is often
+amazing what a tremendous shock a man may receive and yet not be
+killed, and no less amazing how small a shock may kill. It all depends
+on circumstances.”
+
+Josephson shot a covert look at Kennedy. “Yes,” he reiterated, “but I
+cannot see how it _could_ be. If the lights had become short-circuited
+with the bath, that might have thrown a current into the bath. But they
+were not. I know it.”
+
+“Still,” pursued Kennedy, watching him keenly, “it is not all a
+question of current. To kill, the shock must pass through a vital
+organ—the brain, the heart, the upper spinal cord. So, a small shock
+may kill and a large one may not. If it passes in one foot and out by
+the other, the current isn’t likely to be as dangerous as if it passes
+in by a hand or foot and then out by a foot or hand. In one case it
+passes through no vital organ; in the other it is very likely to do so.
+You see, the current can flow through the body only when it has a place
+of entrance and a place of exit. In all cases of accident from electric
+light wires, the victim is touching some conductor—damp earth, salty
+earth, water, something that gives the current an outlet and—”
+
+“But even if the lights had been short-circuited,” interrupted
+Josephson, “Mr. Minturn would have escaped injury unless he had touched
+the taps of the bath. Oh, no, sir, accidents in the medical use of
+electricity are rare. They don’t happen here in my establishment,” he
+maintained stoutly. “The trouble was that the coroner, without any
+knowledge of the physiological effects of electricity on the body,
+simply jumped at once to the conclusion that it was the electric bath
+that did it.”
+
+“Then it was for medical treatment that Mr. Minturn was taking the
+bath?” asked Kennedy, quickly taking up the point.
+
+“Yes, of course,” answered the masseur, eager to explain. “You are
+acquainted with the latest treatment for lead poisoning by means of the
+electric bath?”
+
+Kennedy nodded. “I know that Sir Thomas Oliver, the English authority
+who has written much on dangerous trades, has tried it with marked
+success.”
+
+“Well, sir, that was why Mr. Minturn was here. He came here introduced
+by a Dr. Gunther of Stratfield.”
+
+“Indeed?” remarked Kennedy colorlessly, though I could see that it
+interested him, for evidently Minturn had said nothing of being himself
+a sufferer from the poison. “May I see the bath?”
+
+“Surely,” said Josephson, leading the way upstairs.
+
+It was an oaken tub with metal rods on the two long sides, from which
+depended prismatic carbon rods. Kennedy examined it closely.
+
+“This is what we call a hydro-electric bath,” Josephson explained.
+“Those rods on the sides are the electrodes. You see there are no metal
+parts in the tub itself. The rods are attached by wiring to a wall
+switch out here.”
+
+He pointed to the next room. Kennedy examined the switch with care.
+
+“From it,” went on Josephson, “wires lead to an accumulator battery of
+perhaps thirty volts. It uses very little current. Dr. Gunther tested
+it and found it all right.”
+
+Craig leaned over the bath, and from the carbon electrodes scraped off
+a white powder in minute crystals.
+
+“Ordinarily,” Josephson pursued, “lead is eliminated by the skin and
+kidneys. But now, as you know, it is being helped along by
+electrolysis. I talked to Dr. Gunther about it. It is his opinion that
+it is probably eliminated as a chloride from the tissues of the body to
+the electrodes in the bath in which the patient is wholly or partly
+immersed. On the positive electrodes we get the peroxide. On the
+negative there is a spongy metallic form of lead. But it is only a
+small amount.”
+
+“The body has been removed?” asked Craig.
+
+“Not yet,” the masseur replied. “The coroner has ordered it kept here
+under guard until he makes up his mind what disposition to have made of
+it.”
+
+We were next ushered into a little room on the same floor, at the door
+of which was posted an official from the coroner.
+
+“First of all,” remarked Craig, as he drew back the sheet and began, a
+minute examination of the earthly remains of the great lawyer, “there
+are to be considered the safeguards of the human body against the
+passage through it of a fatal electric current—the high electric
+resistance of the body itself. It is particularly high when the current
+must pass through joints such as wrists, knees, elbows, and quite high
+when the bones of the head are concerned. Still, there might have been
+an incautious application of the current to the head, especially when
+the subject is a person of advanced age or latent cerebral disease,
+though I don’t know that that fits Mr. Minturn. That’s strange,” he
+muttered, looking up, puzzled. “I can find no mark of a burn on the
+body—absolutely no mark of anything.”
+
+“That’s what I say,” put in Josephson, much pleased by what Kennedy
+said, for he had been waiting anxiously to see what Craig discovered on
+his own examination. “It’s impossible.”
+
+“It’s all the more remarkable,” went on Craig, half to himself and
+ignoring Josephson, “because burns due to electric currents are totally
+unlike those produced in other ways. They occur at the point of
+contact, usually about the arms and hands, or the head. Electricity is
+much to be feared when it involves the cranial cavity.” He completed
+his examination of the head which once had carried secrets which
+themselves must have been incandescent.
+
+“Then, too, such burns are most often something more than superficial,
+for considerable heat is developed which leads to massive destruction
+and carbonization of the tissues to a considerable depth. I have seen
+actual losses of substance—a lump of killed flesh surrounded by healthy
+tissues. Besides, such burns show an unexpected indolence when compared
+to the violent pains of ordinary burns. Perhaps that is due to the
+destruction of the nerve endings. How did Minturn die? Was he alone?
+Was he dead when he was discovered?”
+
+“He was alone,” replied Josephson, slowly endeavoring to tell it
+exactly as he had seen it, “but that’s the strange part of it. He
+seemed to be suffering from a convulsion. I think he complained at
+first of a feeling of tightness of his throat and a twitching of the
+muscles of his hands and feet. Anyhow, he called for help. I was up
+here and we rushed in. Dr. Gunther had just brought him and then had
+gone away, after introducing him, and showing him the bath.”
+
+Josephson proceeded slowly, evidently having been warned that anything
+he said might be used against him. “We carried him, when he was this
+way, into this very room. But it was only for a short time. Then came a
+violent convulsion. It seemed to extend rapidly all over his body. His
+legs were rigid, his feet bent, his head back. Why, he was resting only
+on his heels and the back of his head. You see, Mr. Kennedy, that
+simply could not be the electric shock.”
+
+“Hardly,” commented Kennedy, looking again at the body. “It looks more
+like a tetanus convulsion. Yet there does not seem to be any trace of a
+recent wound that might have caused lockjaw. How did he look?”
+
+“Oh, his face finally became livid,” replied Josephson. “He had a
+ghastly, grinning expression, his eyes were wide, there was foam on his
+mouth, and his breathing was difficult.”
+
+“Not like tetanus, either,” revised Craig. “There the convulsion
+usually begins with the face and progresses to the other muscles. Here
+it seems to have gone the other way.”
+
+“That lasted a minute or so,” resumed the masseur. “Then he sank
+back—perfectly limp. I thought he was dead. But he was not. A cold
+sweat broke out all over him and he was as if in a deep sleep.”
+
+“What did you do?” prompted Kennedy.
+
+“I didn’t know what to do. I called an ambulance. But the moment the
+door opened, his body seemed to stiffen again. He had one other
+convulsion—and when he grew limp he was dead.”
+
+
+
+
+CHAPTER XXIX
+THE LEAD POISONER
+
+
+It was a gruesome recital and I was glad to leave the baths finally
+with Kennedy. Josephson was quite evidently relieved at the attitude
+Craig had taken toward the coroner’s conclusion that Minturn had been
+shocked to death. As far as I could see, however, it added to rather
+than cleared up the mystery.
+
+Craig went directly uptown to his laboratory, in contrast with our
+journey down, in abstracted silence, which was his manner when he was
+trying to reason out some particularly knotty problem.
+
+As Kennedy placed the white crystals which he had scraped off the
+electrodes of the tub on a piece of dark paper in the laboratory, he
+wet the tip of his finger and touched just the minutest grain to his
+tongue.
+
+The look on his face told me that something unexpected had happened. He
+held a similar minute speck of the powder out to me.
+
+It was an intensely bitter taste and very persistent, for even after we
+had rinsed out our mouths it seemed to remain, clinging persistently to
+the tongue.
+
+He placed some of the grains in some pure water. They dissolved only
+slightly, if at all. But in a tube in which he mixed a little ether and
+chloroform they dissolved fairly readily.
+
+Next, without a word, he poured just a drop of strong sulphuric acid on
+the crystals. There was not a change in them.
+
+Quickly he reached up into the rack and took down a bottle labeled
+“Potassium Bichromate.”
+
+“Let us see what an oxidizing agent will do,” he remarked.
+
+As he gently added the bichromate, there came a most marvelous,
+kaleidoscopic change. From being almost colorless, the crystals turned
+instantly to a deep blue, then rapidly to purple, lilac, red, and then
+the red slowly faded away and they became colorless again.
+
+“What is it?” I asked, fascinated. “Lead?”
+
+“N-no,” he replied, the lines of his forehead deepening. “No. This is
+sulphate of strychnine.”
+
+“Sulphate of strychnine?” I repeated in astonishment.
+
+“Yes,” he reiterated slowly. “I might have suspected that from the
+convulsions, particularly when Josephson said that the noise and
+excitement of the arrival of the ambulance brought on the fatal
+paroxysm. That is symptomatic. But I didn’t fully realize it until I
+got up here and tasted the stuff. Then I suspected, for that taste is
+characteristic. Even one part diluted seventy thousand times gives that
+decided bitter taste.”
+
+“That’s all very well,” I remarked, recalling the intense bitterness
+yet on my tongue. “But how do you suppose it was possible for anyone to
+administer it? It seems to me that he would have said something, if he
+had swallowed even the minutest part of it. He must have known it. Yet
+apparently he didn’t. At least he said nothing about it—or else
+Josephson is concealing something.”
+
+“Did he swallow it—necessarily?” queried Kennedy, in a tone calculated
+to show me that the chemical world, at least, was full of a number of
+things, and there was much to learn.
+
+“Well, I suppose if it had been given hypodermically, it would have a
+more violent effect,” I persisted, trying to figure out a way that the
+poison might have been given.
+
+“Even more unlikely,” objected Craig, with a delight at discovering a
+new mystery that to me seemed almost fiendish. “No, he would certainly
+have felt a needle, have cried out and said something about it, if
+anyone had tried that. This poisoned needle business isn’t as easy as
+some people seem to think nowadays.”
+
+“Then he might have absorbed it from the water,” I insisted, recalling
+a recent case of Kennedy’s and adding, “by osmosis.”
+
+“You saw how difficult it was to dissolve in water,” Craig rejected
+quietly.
+
+“Well, then,” I concluded in desperation. “How could it have been
+introduced?”
+
+“I have a theory,” was all he would say, reaching for the railway
+guide, “but it will take me up to Stratfield to prove it.”
+
+His plan gave us a little respite and we paused long enough to lunch,
+for which breathing space I was duly thankful. The forenoon saw us on
+the train, Kennedy carrying a large and cumbersome package which he
+brought down with him from the laboratory and which we took turns in
+carrying, though he gave no hint of its contents.
+
+We arrived in Stratfield, a very pretty little mill town, in the middle
+of the afternoon, and with very little trouble were directed to the
+Pearcy house, after Kennedy had checked the parcel with the station
+agent.
+
+Mrs. Pearcy, to whom we introduced ourselves as reporters of the
+_Star_, was a tall blonde. I could not help thinking that she made a
+particularly dashing widow. With her at the time was Isabel Pearcy, a
+slender girl whose sensitive lips and large, earnest eyes indicated a
+fine, high-strung nature.
+
+Even before we had introduced ourselves, I could not help thinking that
+there was a sort of hostility between the women. Certainly it was
+evident that there was as much difference in temperament as between the
+butterfly and the bee.
+
+“No,” replied the elder woman quickly to a request from Kennedy for an
+interview, “there is nothing that I care to say to the newspapers. They
+have said too much already about this—unfortunate affair.”
+
+Whether it was imagination or not, I fancied that there was an air of
+reserve about both women. It struck me as a most peculiar household.
+What was it? Was each suspicious of the other? Was each concealing
+something?
+
+I managed to steal a glance at Kennedy’s face to see whether there was
+anything to confirm my own impression. He was watching Mrs. Pearcy
+closely as she spoke. In fact his next few questions, inconsequential
+as they were, seemed addressed to her solely for the purpose of getting
+her to speak.
+
+I followed his eyes and found that he was watching her mouth, in
+reality. As she answered I noted her beautiful white teeth. Kennedy
+himself had trained me to notice small things, and at the time, though
+I thought it was trivial, I recall noticing on her gums, where they
+joined the teeth, a peculiar bluish-black line.
+
+Kennedy had been careful to address only Mrs. Pearcy at first, and as
+he continued questioning her, she seemed to realize that he was trying
+to lead her along.
+
+“I must positively refuse to talk any more,” she repeated finally,
+rising. “I am not to be tricked into saying anything.”
+
+She had left the room, evidently expecting that Isabel would follow.
+She did not. In fact I felt that Miss Pearcy was visibly relieved by
+the departure of her stepmother. She seemed anxious to ask us something
+and now took the first opportunity.
+
+“Tell me,” she said eagerly, “how did Mr. Minturn die? What do they
+really think of it in New York?”
+
+“They think it is poisoning,” replied Craig, noting the look on her
+face.
+
+She betrayed nothing, as far as I could see, except a natural
+neighborly interest. “Poisoning?” she repeated. “By what?”
+
+“Lead poisoning,” he replied evasively.
+
+She said nothing. It was evident that, slip of a girl though she was,
+she was quite the match of anyone who attempted leading questions.
+Kennedy changed his method.
+
+“You will pardon me,” he said apologetically, “for recalling what must
+be distressing. But we newspapermen often have to do things and ask
+questions that are distasteful. I believe it is rumored that your
+father suffered from lead poisoning?”
+
+“Oh, I don’t know what it was—none of us do,” she cried, almost
+pathetically. “I had been living at the settlement until lately. When
+father grew worse, I came home. He had such strange
+visions—hallucinations, I suppose you would call them. In the daytime
+he would be so very morose and melancholy. Then, too, there were
+terrible pains in his stomach, and his eyesight began to fail. Yes, I
+believe that Dr. Gunther did say it was lead poisoning. But—they have
+said so many things—so many things,” she repeated, plainly distressed
+at the subject of her recent bereavement.
+
+“Your brother is not at home?” asked Kennedy, quickly changing the
+subject.
+
+“No,” she answered, then with a flash as though lifting the veil of a
+confidence, added: “You know, neither Warner nor I have lived here much
+this year. He has been in New York most of the time and I have been at
+the settlement, as I already told you.”
+
+She hesitated, as if wondering whether she should say more, then added
+quickly: “It has been repeated often enough; there is no reason why I
+shouldn’t say it to you. Neither of us exactly approved of father’s
+marriage.”
+
+She checked herself and glanced about, somewhat with the air of one who
+has suddenly considered the possibility of being overheard.
+
+“May I have a glass of water?” asked Kennedy suddenly.
+
+“Why, certainly,” she answered, going to the door, apparently eager for
+an excuse to find out whether there was some one on the other side of
+it.
+
+There was not, nor any indication that there had been.
+
+“Evidently she does not have any suspicions of _that_,” remarked
+Kennedy in an undertone, half to himself.
+
+I had no chance to question him, for she returned almost immediately.
+Instead of drinking the water, however, he held it carefully up to the
+light. It was slightly turbid.
+
+“You drink the water from the tap?” he asked, as he poured some of it
+into a sterilized vial which he drew quickly from his vest pocket.
+
+“Certainly,” she replied, for the moment nonplussed at his strange
+actions. “Everybody drinks the town water in Stratfield.”
+
+A few more questions, none of which were of importance, and Kennedy and
+I excused ourselves.
+
+At the gate, instead of turning toward the town, however, Kennedy went
+on and entered the grounds of the Minturn house next door. The lawyer,
+I had understood, was a widower and, though he lived in Stratfield only
+part of the time, still maintained his house there.
+
+We rang the bell and a middle-aged housekeeper answered.
+
+“I am from the water company,” he began politely. “We are testing the
+water, perhaps will supply consumers with filters. Can you let me have
+a sample?”
+
+She did not demur, but invited us in. As she drew the water, Craig
+watched her hands closely. She seemed to have difficulty in holding the
+glass, and as she handed it to him, I noticed a peculiar hanging down
+of the wrist. Kennedy poured the sample into a second vial, and I
+noticed that it was turbid, too. With no mention of the tragedy to her
+employer, he excused himself, and we walked slowly back to the road.
+
+Between the two houses Kennedy paused, and for several moments appeared
+to be studying them.
+
+We walked slowly back along the road to the town. As we passed the
+local drug store, Kennedy turned and sauntered in.
+
+He found it easy enough to get into conversation with the druggist,
+after making a small purchase, and in the course of a few minutes we
+found ourselves gossiping behind the partition that shut off the arcana
+of the prescription counter from the rest of the store.
+
+Gradually Kennedy led the conversation around to the point which he
+wanted, and asked, “I wish you’d let me fix up a little sulphureted
+hydrogen.”
+
+“Go ahead,” granted the druggist good-naturedly. “I guess you can do
+it. You know as much about drugs as I do. I can stand the smell, if you
+can.”
+
+Kennedy smiled and set to work.
+
+Slowly he passed the gas through the samples of water he had taken from
+the two houses. As he did so the gas, bubbling through, made a blackish
+precipitate.
+
+“What is it?” asked the druggist curiously.
+
+“Lead sulphide,” replied Kennedy, stroking his chin. “This is an
+extremely delicate test. Why, one can get a distinct brownish tinge if
+lead is present in even incredibly minute quantities.”
+
+He continued to work over the vials ranged on the table before him.
+
+“The water contains, I should say, from ten to fifteen hundredths of a
+grain of lead to the gallon,” he remarked finally.
+
+“Where did it come from?” asked the druggist, unable longer to restrain
+his curiosity.
+
+“I got it up at Pearcy’s,” Kennedy replied frankly, turning to observe
+whether the druggist might betray any knowledge of it.
+
+“That’s strange,” he replied in genuine surprise. “Our water in
+Stratfield is supplied by a company to a large area, and it has always
+seemed to me to be of great organic purity.”
+
+“But the pipes are of lead, are they not?” asked Kennedy.
+
+“Y-yes,” answered the druggist, “I think in most places the service
+pipes are of lead. But,” he added earnestly as he saw the implication
+of his admission, “water has never to my knowledge been found to attack
+the pipes so as to affect its quality injuriously.”
+
+He turned his own faucet and drew a glassful. “It is normally quite
+clear,” he added, holding the glass up.
+
+It was in fact perfectly clear, and when he passed some of the gas
+through it nothing happened at all.
+
+Just then a man lounged into the store.
+
+“Hello, Doctor,” greeted the druggist. “Here are a couple of fellows
+that have been investigating the water up at Pearcy’s. They’ve found
+lead in it. That ought to interest you. This is Dr. Gunther,” he
+introduced, turning to us.
+
+It was an unexpected encounter, one I imagine that Kennedy might have
+preferred to take place under other circumstances. But he was equal to
+the occasion.
+
+“We’ve been sent up here to look into the case for the New York
+_Star_,” Kennedy said quickly. “I intended to come around to see you,
+but you have saved me the trouble.”
+
+Dr. Gunther looked from one of us to the other. “Seems to me the New
+York papers ought to have enough to do without sending men all over the
+country making news,” he grunted.
+
+“Well,” drawled Kennedy quietly, “there seems to be a most remarkable
+situation up there at Pearcy’s and Minturn’s, too. As nearly as I can
+make out several people there are suffering from unmistakable signs of
+lead poisoning. There are the pains in the stomach, the colic, and then
+on the gums is that characteristic line of plumbic sulphide, the
+distinctive mark produced by lead. There is the wrist-drop, the
+eyesight affected, the partial paralysis, the hallucinations and a
+condition in old Pearcy’s case almost bordering on insanity—to
+enumerate the symptoms that seem to be present in varying degrees in
+various persons in the two houses.”
+
+Gunther looked at Kennedy, as if in doubt just how to take him.
+
+“That’s what the coroner says, too—lead poisoning,” put in the
+druggist, himself as keen as anyone else for a piece of local news, and
+evidently not averse to stimulating talk from Dr. Gunther, who had been
+Pearcy’s physician.
+
+“That all seems to be true enough,” replied Gunther at length
+guardedly. “I recognized that some time ago.”
+
+“Why do you think it affects each so differently?” asked the druggist.
+
+Dr. Gunther settled himself easily back in a chair to speak as one
+having authority. “Well,” he began slowly, “Miss Pearcy, of course,
+hasn’t been living there much until lately. As for the others, perhaps
+this gentleman here from the _Star_ knows that lead, once absorbed, may
+remain latent in the system and then make itself felt. It is like
+arsenic, an accumulative poison, slowly collecting in the body until
+the limit is reached, or until the body, becoming weakened from some
+other cause, gives way to it.”
+
+He shifted his position slowly, and went on, as if defending the course
+of action he had taken in the case.
+
+“Then, too, you know, there is an individual as well as family and sex
+susceptibility to lead. Women are especially liable to lead poisoning,
+but then perhaps in this case Mrs. Pearcy comes of a family that is
+very resistant. There are many factors. Personally, I don’t think
+Pearcy himself was resistant. Perhaps Minturn was not, either. At any
+rate, after Pearcy’s death, it was I who advised Minturn to take the
+electrolysis cure in New York. I took him down there,” added Gunther.
+“Confound it, I wish I had stayed with him. But I always found
+Josephson perfectly reliable in hydrotherapy with other patients I sent
+to him, and I understood that he had been very successful with cases
+sent to him by many physicians in the city.” He paused and I waited
+anxiously to see whether Kennedy would make some reference to the
+discovery of the strychnine salts.
+
+“Have you any idea how the lead poisoning could have been caused?”
+asked Kennedy instead.
+
+Dr. Gunther shook his head. “It is a puzzle to me,” he answered. “I am
+sure of only one thing. It could not be from working in lead, for it is
+needless to say that none of them worked.”
+
+“Food?” Craig suggested.
+
+The doctor considered. “I had thought of that. I know that many cases
+of lead poisoning have been traced to the presence of the stuff in
+ordinary foods, drugs and drinks. I have examined the foods, especially
+the bread. They don’t use canned goods. I even went so far as to
+examine the kitchen ware to see if there could be anything wrong with
+the glazing. They don’t drink wines and beers, into which now and then
+the stuff seems to get.”
+
+“You seem to have a good grasp of the subject,” flattered Kennedy, as
+we rose to go. “I can hardly blame you for neglecting the water, since
+everyone here seems to be so sure of the purity of the supply.”
+
+Gunther said nothing. I was not surprised, for, at the very least, no
+one likes to have an outsider come in and put his finger directly on
+the raw spot. What more there might be to it, I could only conjecture.
+
+We left the druggist’s and Kennedy, glancing at his watch, remarked:
+“If you will go down to the station, Walter, and get that package we
+left there, I shall be much obliged to you. I want to make just one
+more stop, at the office of the water company, and I think I shall just
+about have time for it. There’s a pretty good restaurant across the
+street. Meet me there, and by that time I shall know whether to carry
+out a little plan I have outlined or not.”
+
+
+
+
+CHAPTER XXX
+THE ELECTROLYTIC MURDER
+
+
+We dined leisurely, which seemed strange to me, for it was not
+Kennedy’s custom to let moments fly uselessly when he was on a case.
+However, I soon found out why it was. He was waiting for darkness.
+
+As soon as the lights began to glow in the little stores on the main
+street, we sallied forth, taking the direction of the Pearcy and
+Minturn houses.
+
+On the way he dropped into the hardware store and purchased a light
+spade and one of the small pocket electric flashlights, about which he
+wrapped a piece of cardboard in such a way as to make a most effective
+dark lantern.
+
+We trudged along in silence, occasionally changing from carrying the
+heavy package to the light spade.
+
+Both the Pearcy and Minturn houses were in nearly total darkness when
+we arrived. They set well back from the road and were plentifully
+shielded by shrubbery. Then, too, at night it was not a much frequented
+neighborhood. We could easily hear the footsteps of anyone approaching
+on the walk, and an occasional automobile gliding past did not worry us
+in the least.
+
+“I have calculated carefully from an examination of the water company’s
+map,” said Craig, “just where the water pipe of the two houses branches
+off from the main in the road.”
+
+After a measurement or two from some landmark, we set to work a few
+feet inside, under cover of the bushes and the shadows, like two grave
+diggers.
+
+Kennedy had been wielding the spade vigorously for a few minutes when
+it touched something metallic. There, just beneath the frost line, we
+came upon the service pipe.
+
+He widened the hole, and carefully scraped off the damp earth that
+adhered to the pipe. Next he found a valve where he shut off the water
+and cut out a small piece of the pipe.
+
+“I hope they don’t suspect anything like this in the houses with their
+water cut off,” he remarked as he carefully split the piece open
+lengthwise and examined it under the light.
+
+On the interior of the pipe could be seen patchy lumps of white which
+projected about an eighth of an inch above the internal surface. As the
+pipe dried in the warm night air, they could easily be brushed off as a
+white powder.
+
+“What is it—strychnine?” I asked.
+
+“No,” he replied, regarding it thoughtfully with some satisfaction.
+“That is lead carbonate. There can be no doubt that the turbidity of
+the water was due to this powder in suspension. A little dissolves in
+the water, while the scales and incrustations in fine particles are
+carried along in the current. As a matter of fact the amount necessary
+to make the water poisonous need not be large.”
+
+He applied a little instrument to the cut ends of the pipe. As I bent
+over, I could see the needle on its dial deflected just a bit.
+
+“My voltmeter,” he said, reading it, “shows that there is a current of
+about 1.8 volts passing through this pipe all the time.”
+
+“Electrolysis of water pipes!” I exclaimed, thinking of statements I
+had heard by engineers. “That’s what they mean by stray or vagabond
+currents, isn’t it?”
+
+He had seized the lantern and was eagerly following up and down the
+line of the water pipe. At last he stopped, with a low exclamation, at
+a point where an electric light wire supplying the Minturn cottage
+crossed overhead. Fastened inconspicuously to the trunk of a tree which
+served as a support for the wire was another wire which led down from
+it and was buried in the ground.
+
+Craig turned up the soft earth as fast as he could, until he reached
+the pipe at this point. There was the buried wire wound several times
+around it.
+
+As quickly and as neatly as he could he inserted a connection between
+the severed ends of the pipe to restore the flow of water to the
+houses, turned on the water and covered up the holes he had dug. Then
+he unwrapped the package which we had tugged about all day, and in a
+narrow path between the bushes which led to the point where the wire
+had tapped the electric light feed he placed in a shallow hole in the
+ground a peculiar apparatus.
+
+As nearly as I could make it out, it consisted of two flat platforms
+between which, covered over and projected, was a slip of paper which
+moved forward, actuated by clockwork, and pressed on by a sort of
+stylus. Then he covered it over lightly with dirt so that, unless
+anyone had been looking for it, it would never be noticed.
+
+It was late when we reached the city again, but Kennedy had one more
+piece of work and that devolved on me. All the way down on the train he
+had been writing and rewriting something.
+
+“Walter,” he said, as the train pulled into the station, “I want that
+published in to-morrow’s papers.”
+
+I looked over what he had written. It was one of the most sensational
+stories I have ever fathered, beginning, “Latest of the victims of the
+unknown poisoner of whole families in Stratfield, Connecticut, is Miss
+Isabel Pearcy, whose father, Randall Pearcy, died last week.”
+
+I knew that it was a “plant” of some kind, for so far he had discovered
+no evidence that Miss Pearcy had been affected. What his purpose was, I
+could not guess, but I got the story printed.
+
+The next morning early Kennedy was quietly at work in the laboratory.
+
+“What is this treatment of lead poisoning by electrolysis?” I asked,
+now that there had come a lull when I might get an intelligible answer.
+“How does it work?”
+
+“Brand new, Walter,” replied Kennedy. “It has been discovered that ions
+will flow directly through the membranes.”
+
+“Ions?” I repeated. “What are ions?”
+
+“Travelers,” he answered, smiling, “so named by Faraday from the Greek
+verb, _io_, to go. They are little positive and negative charges of
+electricity of which molecules are composed. You know some believe now
+that matter is really composed of electrical energy. I think I can
+explain it best by a simile I use with my classes. It is as though you
+had a ballroom in which the dancers in couples represent the neutral
+molecules. There are a certain number of isolated ladies and
+gentlemen—dissociated ions—” “Who don’t know these new dances?” I
+interrupted.
+
+“They all know this dance,” he laughed. “But, to be serious in the
+simile, suppose at one end of the room there is a large mirror and at
+the other a buffet with cigars and champagne. What happens to the
+dissociated ions?”
+
+“Well, I suppose you want me to say that the ladies gather about the
+mirror and the men about the buffet.”
+
+“Exactly. And some of the dancing partners separate and follow the
+crowd. Well, that room presents a picture of what happens in an
+electrolytic solution at the moment when the electric current is
+passing through it.”
+
+“Thanks,” I laughed. “That was quite adequate to my immature
+understanding.”
+
+Kennedy continued at work, checking up and arranging his data until the
+middle of the afternoon, when he went up to Stratfield.
+
+Having nothing better to do, I wandered out about town in the hope of
+running across some one with whom to while away the hours until Kennedy
+returned. I found out that, since yesterday, Broadway had woven an
+entirely new background for the mystery. Now it was rumored that the
+lawyer Minturn himself had been on very intimate terms with Mrs.
+Pearcy. I did not pay much attention to the rumor, for I knew that
+Broadway is constitutionally unable to believe that anybody is
+straight.
+
+Kennedy had commissioned me to keep in touch with Josephson and I
+finally managed to get around to the Baths, to find them still closed.
+
+As I was talking with him, a very muddy and dusty car pulled up at the
+door and a young man whose face was marred by the red congested blood
+vessels that are in some a mark of dissipation burst in on us.
+
+“What—closed up yet—Joe?” he asked. “Haven’t they taken Minturn’s body
+away?”
+
+“Yes, it was sent up to Stratfield to-day,” replied the masseur, “but
+the coroner seems to want to worry me all he can.”
+
+“Too bad. I was up almost all last night, and to-day I have been out in
+my car—tired to death. Thought I might get some rest here. Where are
+you sending the boys—to the Longacre?”
+
+“Yes. They’ll take good care of you till I open up again. Hope to see
+you back again, then, Mr. Pearcy,” he added, as the young man turned
+and hurried out to his car again. “That was that young Pearcy, you
+know. Nice boy—but living the life too fast. What’s Kennedy
+doing—anything?”
+
+I did not like the jaunty bravado of the masseur which now seemed to be
+returning, since nothing definite had taken shape. I determined that he
+should not pump me, as he evidently was trying to do. I had at least
+fulfilled Kennedy’s commission and felt that the sooner I left
+Josephson the better for both of us.
+
+I was surprised at dinner to receive a wire from Craig saying that he
+was bringing down Dr. Gunther, Mrs. Pearcy and Isabel to New York and
+asking me to have Warner Pearcy and Josephson at the laboratory at nine
+o’clock.
+
+By strategy I managed to persuade Pearcy to come, and as for Josephson,
+he could not very well escape, though I saw that as long as nothing
+more had happened, he was more interested in “fixing” the police so
+that he could resume business than anything else.
+
+As we entered the laboratory that night, Kennedy, who had left his
+party at a downtown hotel to freshen up, met us each at the door.
+Instead of conducting us in front of his laboratory table, which was
+the natural way, he led us singly around through the narrow space back
+of it.
+
+I recall that as I followed him, I half imagined that the floor gave
+way just a bit, and there flashed over me, by a queer association of
+ideas, the recollection of having visited an amusement park not long
+before where merely stepping on an innocent-looking section of the
+flooring had resulted in a tremendous knocking and banging beneath,
+much to the delight of the lovers of slap-stick humor. This was serious
+business, however, and I quickly banished the frivolous thought from my
+mind.
+
+“The discovery of poison, and its identification,” began Craig at last
+when we had all arrived and were seated about him, “often involves not
+only the use of chemistry but also a knowledge of the chemical effect
+of the poison on the body, and the gross as well as microscopic changes
+which it produces in various tissues and organs—changes, some due to
+mere contact, others to the actual chemicophysiological reaction
+between the poison and the body.”
+
+His hand was resting on the poles of a large battery, as he proceeded:
+“Every day the medical detective plays a more and more important part
+in the detection of crime, and I might say that, except in the case of
+crime complicated by a lunacy plea, his work has earned the respect of
+the courts and of detectives, while in the case of insanity the
+discredit is the fault rather of the law itself. The ways in which the
+doctor can be of use in untangling the facts in many forms of crime
+have become so numerous that the profession of medical detective may
+almost be called a specialty.”
+
+Kennedy repeated what he had already told me about electrolysis, then
+placed between the poles of the battery a large piece of raw beef.
+
+He covered the negative electrode with blotting paper and soaked it in
+a beaker near at hand.
+
+“This solution,” he explained, “is composed of potassium iodide. In
+this other beaker I have a mixture of ordinary starch.”
+
+He soaked the positive electrode in the starch and then jammed the two
+against the soft red meat. Then he applied the current.
+
+A few moments later he withdrew the positive electrode. Both it and the
+meat under it were blue!
+
+“What has happened?” he asked. “The iodine ions have actually passed
+through the beef to the positive pole and the paper on the electrode.
+Here we have starch iodide.”
+
+It was a startling idea, this of the introduction of a substance by
+electrolysis.
+
+“I may say,” he resumed, “that the medical view of electricity is
+changing, due in large measure to the genius of the Frenchman, Dr.
+Leduc. The body, we know, is composed largely of water, with salts of
+soda and potash. It is an excellent electrolyte. Yet most doctors
+regard the introduction of substances by the electric current as
+insignificant or nonexistent. But on the contrary the introduction of
+drugs by electrolysis is regular and far from being insignificant may
+very easily bring about death.
+
+“That action,” he went on, looking from one of us to another, “may be
+therapeutic, as in the cure for lead poisoning by removing the lead, or
+it may be toxic—as in the case of actually introducing such a poison as
+strychnine into the body by the same forces that will remove the lead.”
+
+He paused a moment, to enforce the point which had already been
+suggested. I glanced about hastily. If anyone in his little audience
+was guilty, no one betrayed it, for all were following him, fascinated.
+Yet in the wildly throbbing brain of some one of them the guilty
+knowledge must be seared indelibly. Would the mere accusation be enough
+to dissociate the truth from, that brain or would Kennedy have to
+resort to other means?
+
+“Some one,” he went on, in a low, tense voice, leaning forward, “some
+one who knew this effect placed strychnine salts on one of the
+electrodes of the bath which Owen Minturn was to use.”
+
+He did not pause. Evidently he was planning to let the force of his
+exposure be cumulative, until from its sheer momentum it carried
+everything before it.
+
+“Walter,” he ordered quickly. “Lend me a hand.”
+
+Together we moved the laboratory table as he directed.
+
+There, in the floor, concealed by the shadow, he had placed the same
+apparatus which I had seen him bury in the path between the Pearcy and
+Minturn estates at Stratfield.
+
+We scarcely breathed.
+
+“This,” he explained rapidly, “is what is known as a kinograph—the
+invention of Professor HeleShaw of London. It enables me to identify a
+person by his or her walk. Each of you as you entered this room has
+passed over this apparatus and has left a different mark on the paper
+which registers.”
+
+For a moment he stopped, as if gathering strength for the final
+assault.
+
+“Until late this afternoon I had this kinograph secreted at a certain
+place in Stratfield. Some one had tampered with the leaden water pipes
+and the electric light cable. Fearful that the lead poisoning brought
+on by electrolysis might not produce its result in the intended victim,
+that person took advantage of the new discoveries in electrolysis to
+complete that work by introducing the deadly strychnine during the very
+process of cure of the lead poisoning.”
+
+He slapped down a copy of a newspaper. “In the news this morning I told
+just enough of what I had discovered and colored it in such a way that
+I was sure I would arouse apprehension. I did it because I wanted to
+make the criminal revisit the real scene of the crime. There was a
+double motive now—to remove the evidence and to check the spread of the
+poisoning.”
+
+He reached over, tore off the paper with a quick, decisive motion, and
+laid it beside another strip, a little discolored by moisture, as
+though the damp earth had touched it.
+
+“That person, alarmed lest something in the cleverly laid plot, might
+be discovered, went to a certain spot to remove the traces of the
+diabolical work which were hidden there. My kinograph shows the
+footsteps, shows as plainly as if I had been present, the exact person
+who tried to obliterate the evidence.”
+
+An ashen pallor seemed to spread over the face of Miss Pearcy, as
+Kennedy shot out the words.
+
+“That person,” he emphasized, “had planned to put out of the way one
+who had brought disgrace on the Pearcy family. It was an act of private
+justice.”
+
+Mrs. Pearcy could stand the strain no longer. She had broken down and
+was weeping incoherently. I strained my ears to catch what she was
+murmuring. It was Minturn’s name, not Gunther’s, that was on her lips.
+
+“But,” cried Kennedy, raising an accusatory finger from the kinograph
+tracing and pointing it like the finger of Fate itself, “but the
+self-appointed avenger forgot that the leaden water pipe was common to
+the two houses. Old Mr. Pearcy, the wronged, died first. Isabel has
+guessed the family skeleton—has tried hard to shield you, but, Warner
+Pearcy, you are the murderer!”
+
+
+
+
+CHAPTER XXXI
+THE EUGENIC BRIDE
+
+
+Scandal, such as that which Kennedy unearthed in this Pearcy case, was
+never much to his liking, yet he seemed destined, about this period of
+his career, to have a good deal of it.
+
+We had scarcely finished with the indictment that followed the arrest
+of young Pearcy, when we were confronted by a situation which was as
+unique as it was intensely modern.
+
+“There’s absolutely no insanity in Eugenia’s family,” I heard a young
+man remark to Kennedy, as my key turned in the lock of the laboratory
+door.
+
+For a moment I hesitated about breaking in on a confidential
+conference, then reflected that, as they had probably already heard me
+at the lock, I had better go in and excuse myself.
+
+As I swung the door open, I saw a young man pacing up and down the
+laboratory nervously, too preoccupied even to notice the slight noise I
+had made.
+
+He paused in his nervous walk and faced Kennedy, his back to me.
+
+“Kennedy,” he said huskily, “I wouldn’t care if there was insanity in
+her family—for, my God!—the tragedy of it all now—I love her!”
+
+He turned, following Kennedy’s eyes in my direction, and I saw on his
+face the most haggard, haunting look of anxiety that I had ever seen on
+a young person.
+
+Instantly I recognized from the pictures I had seen in the newspapers
+young Quincy Atherton, the last of this famous line of the family, who
+had attracted a great deal of attention several months previously by
+what the newspapers had called his search through society for a
+“eugenics bride,” to infuse new blood into the Atherton stock.
+
+“You need have no fear that Mr. Jameson will be like the other
+newspaper men,” reassured Craig, as he introduced us, mindful of the
+prejudice which the unpleasant notoriety of Atherton’s marriage had
+already engendered in his mind.
+
+I recalled that when I had first heard of Atherton’s “eugenic
+marriage,” I had instinctively felt a prejudice against the very idea
+of such cold, calculating, materialistic, scientific mating, as if one
+of the last fixed points were disappearing in the chaos of the social
+and sex upheaval.
+
+Now, I saw that one great fact of life must always remain. We might
+ride in hydroaeroplanes, delve into the very soul by psychanalysis,
+perhaps even run our machines by the internal forces of radium—even
+marry according to Galton or Mendel. But there would always be love,
+deep passionate love of the man for the woman, love which all the
+discoveries of science might perhaps direct a little less blindly, but
+the consuming flame of which not all the coldness of science could ever
+quench. No tampering with the roots of human nature could ever change
+the roots.
+
+I must say that I rather liked young Atherton. He had a frank, open
+face, the most prominent feature of which was his somewhat aristocratic
+nose. Otherwise he impressed one as being the victim of heredity in
+faults, if at all serious, against which he was struggling heroically.
+
+It was a most pathetic story which he told, a story of how his family
+had degenerated from the strong stock of his ancestors until he was the
+last of the line. He told of his education, how he had fallen, a rather
+wild youth bent in the footsteps of his father who had been a
+notoriously good clubfellow, under the influence of a college
+professor, Dr. Crafts, a classmate of his father’s, of how the
+professor had carefully and persistently fostered in him an idea that
+had completely changed him.
+
+“Crafts always said it was a case of eugenics against euthenics,”
+remarked Atherton, “of birth against environment. He would tell me over
+and over that birth gave me the clay, and it wasn’t such bad clay after
+all, but that environment would shape the vessel.”
+
+Then Atherton launched into a description of how he had striven to find
+a girl who had the strong qualities his family germ plasm seemed to
+have lost, mainly, I gathered, resistance to a taint much like manic
+depressive insanity. And as he talked, it was borne in on me that,
+after all, contrary to my first prejudice, there was nothing very
+romantic indeed about disregarding the plain teachings of science on
+the subject of marriage and one’s children.
+
+In his search for a bride, Dr. Crafts, who had founded a sort of
+Eugenics Bureau, had come to advise him. Others may have looked up
+their brides in Bradstreet’s, or at least the Social Register. Atherton
+had gone higher, had been overjoyed to find that a girl he had met in
+the West, Eugenia Gilman, measured up to what his friend told him were
+the latest teachings of science. He had been overjoyed because, long
+before Crafts had told him, he had found out that he loved her deeply.
+
+“And now,” he went on, half choking with emotion, “she is apparently
+suffering from just the same sort of depression as I myself might
+suffer from if the recessive trait became active.”
+
+“What do you mean, for instance?” asked Craig.
+
+“Well, for one thing, she has the delusion that my relatives are
+persecuting her.”
+
+“Persecuting her?” repeated Craig, stifling the remark that that was
+not in itself a new thing in this or any other family. “How?”
+
+“Oh, making her feel that, after all, it is Atherton family rather than
+Gilman health that counts—little remarks that when our baby is born,
+they hope it will resemble Quincy rather than Eugenia, and all that
+sort of thing, only worse and more cutting, until the thing has begun
+to prey on her mind.”
+
+“I see,” remarked Kennedy thoughtfully. “But don’t you think this is a
+case for a—a doctor, rather than a detective?”
+
+Atherton glanced up quickly. “Kennedy,” he answered slowly, “where
+millions of dollars are involved, no one can guess to what lengths the
+human mind will go—no one, except you.”
+
+“Then you have suspicions of something worse?”
+
+“Y-yes—but nothing definite. Now, take this case. If I should die
+childless, after my wife, the Atherton estate would descend to my
+nearest relative, Burroughs Atherton, a cousin.”
+
+“Unless you willed it to—”
+
+“I have already drawn a will,” he interrupted, “and in case I survive
+Eugenia and die childless, the money goes to the founding of a larger
+Eugenics Bureau, to prevent in the future, as much as possible,
+tragedies such as this of which I find myself a part. If the case is
+reversed, Eugenia will get her third and the remainder will go to the
+Bureau or the Foundation, as I call the new venture. But,” and here
+young Atherton leaned forward and fixed his large eyes keenly on us,
+“Burroughs might break the will. He might show that I was of unsound
+mind, or that Eugenia was, too.”
+
+“Are there no other relatives?”
+
+“Burroughs is the nearest,” he replied, then added frankly, “I have a
+second cousin, a young lady named Edith Atherton, with whom both
+Burroughs and I used to be very friendly.”
+
+It was evident from the way he spoke that he had thought a great deal
+about Edith Atherton, and still thought well of her.
+
+“Your wife thinks it is Burroughs who is persecuting her?” asked
+Kennedy.
+
+Atherton shrugged his shoulders.
+
+“Does she get along badly with Edith? She knows her I presume?”
+
+“Of course. The fact is that since the death of her mother, Edith has
+been living with us. She is a splendid girl, and all alone in the world
+now, and I had hopes that in New York she might meet some one and marry
+well.”
+
+Kennedy was looking squarely at Atherton, wondering whether he might
+ask a question without seeming impertinent. Atherton caught the look,
+read it, and answered quite frankly, “To tell the truth, I suppose I
+might have married Edith, before I met Eugenia, if Professor Crafts had
+not dissuaded me. But it wouldn’t have been real love—nor wise. You
+know,” he went on more frankly, now that the first hesitation was over
+and he realized that if he were to gain anything at all by Kennedy’s
+services, there must be the utmost candor between them, “you know
+cousins may marry if the stocks are known to be strong. But if there is
+a defect, it is almost sure to be intensified. And so I—I gave up the
+idea—never had it, in fact, so strongly as to propose to her. And when
+I met Eugenia all the Athertons on the family tree couldn’t have bucked
+up against the combination.”
+
+He was deadly in earnest as he arose from the chair into which he had
+dropped after I came in.
+
+“Oh, it’s terrible—this haunting fear, this obsession that I have had,
+that, in spite of all I have tried to do, some one, somehow, will
+defeat me. Then comes the situation, just at a time when Eugenia and I
+feel that we have won against Fate, and she in particular needs all the
+consideration and care in the world—and—and I am defeated.”
+
+Atherton was again pacing the laboratory.
+
+“I have my car waiting outside,” he pleaded. “I wish you would go with
+me to see Eugenia—now.”
+
+It was impossible to resist him. Kennedy rose and I followed, not
+without a trace of misgiving.
+
+The Atherton mansion was one of the old houses of the city, a somber
+stone dwelling with a garden about it on a downtown square, on which
+business was already encroaching. We were admitted by a servant who
+seemed to walk over the polished floors with stealthy step as if there
+was something sacred about even the Atherton silence. As we waited in a
+high-ceilinged drawing-room with exquisite old tapestries on the walls,
+I could not help feeling myself the influence of wealth and birth that
+seemed to cry out from every object of art in the house.
+
+On the longer wall of the room, I saw a group of paintings. One, I
+noted especially, must have been Atherton’s ancestor, the founder of
+the line. There was the same nose in Atherton, for instance, a striking
+instance of heredity. I studied the face carefully. There was every
+element of strength in it, and I thought instinctively that, whatever
+might have been the effects of in-breeding and bad alliances, there
+must still be some of that strength left in the present descendant of
+the house of Atherton. The more I thought about the house, the
+portrait, the whole case, the more unable was I to get out of my head a
+feeling that though I had not been in such a position before, I had at
+least read or heard something of which it vaguely reminded me.
+
+Eugenia Atherton was reclining listlessly in her room in a deep leather
+easy chair, when Atherton took us up at last. She did not rise to greet
+us, but I noted that she was attired in what Kennedy once called, as we
+strolled up the Avenue, “the expensive sloppiness of the present
+styles.” In her case the looseness with which her clothes hung was
+exaggerated by the lack of energy with which she wore them.
+
+She had been a beautiful girl, I knew. In fact, one could see that she
+must have been. Now, however, she showed marks of change. Her eyes were
+large, and protruding, not with the fire of passion which is often
+associated with large eyes, but dully, set in a puffy face, a trifle
+florid. Her hands seemed, when she moved them, to shake with an
+involuntary tremor, and in spite of the fact that one almost could feel
+that her heart and lungs were speeding with energy, she had lost weight
+and no longer had the full, rounded figure of health. Her manner showed
+severe mental disturbance, indifference, depression, a distressing
+deterioration. All her attractive Western breeziness was gone. One felt
+the tragedy of it only too keenly.
+
+“I have asked Professor Kennedy, a specialist, to call, my dear,” said
+Atherton gently, without mentioning what the specialty was.
+
+“Another one?” she queried languorously.
+
+There was a colorless indifference in the tone which was almost tragic.
+She said the words slowly and deliberately, as though even her mind
+worked that way.
+
+From the first, I saw that Kennedy had been observing Eugenia Atherton
+keenly. And in the role of specialist in nervous diseases he was
+enabled to do what otherwise would have been difficult to accomplish.
+
+Gradually, from observing her mental condition of indifference which
+made conversation extremely difficult as well as profitless, he began
+to consider her physical condition. I knew him well enough to gather
+from his manner alone as he went on that what had seemed at the start
+to be merely a curious case, because it concerned the Athertons, was
+looming up in his mind as unusual in itself, and was interesting him
+because it baffled him.
+
+Craig had just discovered that her pulse was abnormally high, and that
+consequently she had a high temperature, and was sweating profusely.
+
+“Would you mind turning your head, Mrs. Atherton?” he asked.
+
+She turned slowly, half way, her eyes fixed vacantly on the floor until
+we could see the once striking profile.
+
+“No, all the way around, if you please,” added Kennedy.
+
+She offered no objection, not the slightest resistance. As she turned
+her head as far as she could, Kennedy quickly placed his forefinger and
+thumb gently on her throat, the once beautiful throat, now with skin
+harsh and rough. Softly he moved his fingers just a fraction of an inch
+over the so-called “Adam’s apple” and around it for a little distance.
+
+“Thank you,” he said. “Now around to the other side.”
+
+He made no other remark as he repeated the process, but I fancied I
+could tell that he had had an instant suspicion of something the moment
+he touched her throat.
+
+He rose abstractedly, bowed, and we started to leave the room,
+uncertain whether she knew or cared. Quincy had fixed his eyes silently
+on Craig, as if imploring him to speak, but I knew how unlikely that
+was until he had confirmed his suspicion to the last slightest detail.
+
+We were passing through a dressing room in the suite when we met a tall
+young woman, whose face I instantly recognized, not because I had ever
+seen it before, but because she had the Atherton nose so prominently
+developed.
+
+“My cousin, Edith,” introduced Quincy.
+
+We bowed and stood for a moment chatting. There seemed to be no reason
+why we should leave the suite, since Mrs. Atherton paid so little
+attention to us even when we had been in the same room. Yet a slight
+movement in her room told me that in spite of her lethargy she seemed
+to know that we were there and to recognize who had joined us.
+
+Edith Atherton was a noticeable woman, a woman of temperament, not
+beautiful exactly, but with a stateliness about her, an aloofness. The
+more I studied her face, with its thin sensitive lips and commanding,
+almost imperious eyes, the more there seemed to be something peculiar
+about her. She was dressed very simply in black, but it was the
+simplicity that costs. One thing was quite evident—her pride in the
+family of Atherton.
+
+And as we talked, it seemed to be that she, much more than Eugenia in
+her former blooming health, was a part of the somber house. There came
+over me again the impression I had received before that I had read or
+heard something like this case before.
+
+She did not linger long, but continued her stately way into the room
+where Eugenia sat. And at once it flashed over me what my impression,
+indefinable, half formed, was. I could not help thinking, as I saw her
+pass, of the lady Madeline in “The Fall of the House of Usher.”
+
+
+
+
+CHAPTER XXXII
+THE GERM PLASM
+
+
+I regarded her with utter astonishment and yet found it impossible to
+account for such a feeling. I looked at Atherton, but on his face I
+could see nothing but a sort of questioning fear that only increased my
+illusion, as if he, too, had only a vague, haunting premonition of
+something terrible impending. Almost I began to wonder whether the
+Atherton house might not crumble under the fierceness of a sudden
+whirlwind, while the two women in this case, one representing the
+wasted past, the other the blasted future, dragged Atherton down, as
+the whole scene dissolved into some ghostly tarn. It was only for a
+moment, and then I saw that the more practical Kennedy had been
+examining some bottles on the lady’s dresser before which we had
+paused.
+
+One was a plain bottle of pellets which might have been some
+homeopathic remedy.
+
+“Whatever it is that is the matter with Eugenia,” remarked Atherton,
+“it seems to have baffled the doctors so far.”
+
+Kennedy said nothing, but I saw that he had clumsily overturned the
+bottle and absently set it up again, as though his thoughts were far
+away. Yet with a cleverness that would have done credit to a professor
+of legerdemain he had managed to extract two or three of the pellets.
+
+“Yes,” he said, as he moved slowly toward the staircase in the wide
+hall, “most baffling.”
+
+Atherton was plainly disappointed. Evidently he had expected Kennedy to
+arrive at the truth and set matters right by some sudden piece of
+wizardry, and it was with difficulty that he refrained from saying so.
+
+“I should like to meet Burroughs Atherton,” he remarked as we stood in
+the wide hall on the first floor of the big house. “Is he a frequent
+visitor?”
+
+“Not frequent,” hastened Quincy Atherton, in a tone that showed some
+satisfaction in saying it. “However, by a lucky chance he has promised
+to call to-night—a mere courtesy, I believe, to Edith, since she has
+come to town on a visit.”
+
+“Good!” exclaimed Kennedy. “Now, I leave it to you, Atherton, to make
+some plausible excuse for our meeting Burroughs here.”
+
+“I can do that easily.”
+
+“I shall be here early,” pursued Kennedy as we left.
+
+Back again in the laboratory to which Atherton insisted on accompanying
+us in his car, Kennedy busied himself for a few minutes, crushing up
+one of the tablets and trying one or two reactions with some of the
+powder dissolved, while I looked on curiously.
+
+“Craig,” I remarked contemplatively, after a while, “how about Atherton
+himself? Is he really free from the—er—stigmata, I suppose you call
+them, of insanity?”
+
+“You mean, may the whole trouble lie with him?” he asked, not looking
+up from his work.
+
+“Yes—and the effect on her be a sort of reflex, say, perhaps the effect
+of having sold herself for money and position. In other words, does
+she, did she, ever love him? We don’t know that. Might it not prey on
+her mind, until with the kind help of his precious relatives even
+Nature herself could not stand the strain—especially in the delicate
+condition in which she now finds herself?”
+
+I must admit that I felt the utmost sympathy for the poor girl whom we
+had just seen such a pitiable wreck.
+
+Kennedy closed his eyes tightly until they wrinkled at the corners.
+
+“I think I have found out the immediate cause of her trouble,” he said
+simply, ignoring my suggestion.
+
+“What is it?” I asked eagerly.
+
+“I can’t imagine how they could have failed to guess it, except that
+they never would have suspected to look for anything resembling
+exophthalmic goiter in a person of her stamina,” he answered,
+pronouncing the word slowly. “You have heard of the thyroid gland in
+the neck?”
+
+“Yes?” I queried, for it was a mere name to me.
+
+“It is a vascular organ lying under the chin with a sort of little
+isthmus joining the two parts on either side of the windpipe,” he
+explained. “Well, when there is any deterioration of those glands
+through any cause, all sorts of complications may arise. The thyroid is
+one of the so-called ductless glands, like the adrenals above the
+kidneys, the pineal gland and the pituitary body. In normal activity
+they discharge into the blood substances which are carried to other
+organs and are now known to be absolutely essential.
+
+“The substances which they secrete are called ‘hormones’—those chemical
+messengers, as it were, by which many of the processes of the body are
+regulated. In fact, no field of experimental physiology is richer in
+interest than this. It seems that few ordinary drugs approach in their
+effects on metabolism the hormones of the thyroid. In excess they
+produce such diseases as exophthalmic goiter, and goiter is concerned
+with the enlargement of the glands and surrounding tissues beyond
+anything like natural size. Then, too, a defect in the glands causes
+the disease known as myxedema in adults and cretinism in children. Most
+of all, the gland seems to tell on the germ plasm of the body,
+especially in women.”
+
+I listened in amazement, hardly knowing what to think. Did his
+discovery portend something diabolical, or was it purely a defect in
+nature which Dr. Crafts of the Eugenics Bureau had overlooked?
+
+“One thing at a time, Walter,” cautioned Kennedy, when I put the
+question to him, scarcely expecting an answer yet.
+
+That night in the old Atherton mansion, while we waited for Borroughs
+to arrive, Kennedy, whose fertile mind had contrived to kill at least
+two birds with one stone, busied himself by cutting in on the regular
+telephone line and placing an extension of his own in a closet in the
+library. To it he attached an ordinary telephone receiver fastened to
+an arrangement which was strange to me. As nearly as I can describe it,
+between the diaphragm of the regular receiver and a brownish cylinder,
+like that of a phonograph, and with a needle attached, was fitted an
+air chamber of small size, open to the outer air by a small hole to
+prevent compression.
+
+The work was completed expeditiously, but we had plenty of time to
+wait, for Borroughs Atherton evidently did not consider that an evening
+had fairly begun until nine o’clock.
+
+He arrived at last, however, rather tall, slight of figure,
+narrow-shouldered, designed for the latest models of imported fabrics.
+It was evident merely by shaking hands with Burroughs that he thought
+both the Athertons and the Burroughses just the right combination. He
+was one of those few men against whom I conceive an instinctive
+prejudice, and in this case I felt positive that, whatever faults the
+Atherton germ plasm might contain, he had combined others from the
+determiners of that of the other ancestors he boasted. I could not help
+feeling that Eugenia Atherton was in about as unpleasant an atmosphere
+of social miasma as could be imagined.
+
+Burroughs asked politely after Eugenia, but it was evident that the
+real deference was paid to Edith Atherton and that they got along very
+well together. Burroughs excused himself early, and we followed soon
+after.
+
+“I think I shall go around to this Eugenics Bureau of Dr. Crafts,”
+remarked Kennedy the next day, after a night’s consideration of the
+case.
+
+The Bureau occupied a floor in a dwelling house uptown which had been
+remodeled into an office building. Huge cabinets were stacked up
+against the walls, and in them several women were engaged in filing
+blanks and card records. Another part of the office consisted of an
+extensive library on eugenic subjects.
+
+Dr. Crafts, in charge of the work, whom we found in a little office in
+front partitioned off by ground glass, was an old man with an alert,
+vigorous mind on whom the effects of plain living and high thinking
+showed plainly. He was looking over some new blanks with a young woman
+who seemed to be working with him, directing the force of clerks as
+well as the “field workers,” who were gathering the vast mass of
+information which was being studied. As we introduced ourselves, he
+introduced Dr. Maude Schofield.
+
+“I have heard of your eugenic marriage contests,” began Kennedy, “more
+especially of what you have done for Mr. Quincy Atherton.”
+
+“Well—not exactly a contest in that case, at least,” corrected Dr.
+Crafts with an indulgent smile for a layman.
+
+“No,” put in Dr. Schofield, “the Eugenics Bureau isn’t a human stock
+farm.”
+
+“I see,” commented Kennedy, who had no such idea, anyhow. He was always
+lenient with anyone who had what he often referred to as the “illusion
+of grandeur.”
+
+“We advise people sometimes regarding the desirability or the
+undesirability of marriage,” mollified Dr. Crafts. “This is a sort of
+clearing house for scientific race investigation and improvement.”
+
+“At any rate,” persisted Kennedy, “after investigation, I understand,
+you advised in favor of his marriage with Miss Gilman.”
+
+“Yes, Eugenia Gilman seemed to measure well up to the requirements in
+such a match. Her branch of the Gilmans has always been of the
+vigorous, pioneering type, as well as intellectual. Her father was one
+of the foremost thinkers in the West; in fact had long held ideas on
+the betterment of the race. You see that in the choice of a name for
+his daughter—Eugenia.”
+
+“Then there were no recessive traits in her family,” asked Kennedy
+quickly, “of the same sort that you find in the Athertons?”
+
+“None that we could discover,” answered Dr. Crafts positively.
+
+“No epilepsy, no insanity of any form?”
+
+“No. Of course, you understand that almost no one is what might be
+called eugenically perfect. Strictly speaking, perhaps not over two or
+three per cent. of the population even approximates that standard. But
+it seemed to me that in everything essential in this case, weakness
+latent in Atherton was mating strength in Eugenia and the same way on
+her part for an entirely different set of traits.”
+
+“Still,” considered Kennedy, “there might have been something latent in
+her family germ plasm back of the time through which you could trace
+it?”
+
+Dr. Crafts shrugged his shoulders. “There often is, I must admit,
+something we can’t discover because it lies too far back in the past.”
+
+“And likely to crop out after skipping generations,” put in Maude
+Schofield.
+
+She evidently did not take the same liberal view in the practical
+application of the matter expressed by her chief. I set it down to the
+ardor of youth in a new cause, which often becomes the saner
+conservatism of maturity.
+
+“Of course, you found it much easier than usual to get at the true
+family history of the Athertons,” pursued Kennedy. “It is an old family
+and has been prominent for generations.”
+
+“Naturally,” assented Dr. Crafts.
+
+“You know Burroughs Atherton on both lines of descent?” asked Kennedy,
+changing the subject abruptly.
+
+“Yes, fairly well,” answered Crafts.
+
+“Now, for example,” went on Craig, “how would you advise him to marry?”
+
+I saw at once that he was taking this subterfuge as a way of securing
+information which might otherwise have been withheld if asked for
+directly. Maude Schofield also saw it, I fancied, but this time said
+nothing. “They had a grandfather who was a manic depressive on the
+Atherton side,” said Crafts slowly. “Now, no attempt has ever been made
+to breed that defect out of the family. In the case of Burroughs, it is
+perhaps a little worse, for the other side of his ancestry is not free
+from the taint of alcoholism.”
+
+“And Edith Atherton?”
+
+“The same way. They both carry it. I won’t go into the Mendelian law on
+the subject. We are clearing up much that is obscure. But as to
+Burroughs, he should marry, if at all, some one without that particular
+taint. I believe that in a few generations by proper mating most taints
+might be bred out of families.”
+
+Maude Schofield evidently did not agree with Dr. Crafts on some point,
+and, noticing it, he seemed to be in the position both of explaining
+his contention to us and of defending it before his fair assistant.
+
+“It is my opinion, as far as I have gone with the data,” he added,
+“that there is hope for many of those whose family history shows
+certain nervous taints. A sweeping prohibition of such marriages would
+be futile, perhaps injurious. It is necessary that the mating be
+carefully made, however, to prevent intensifying the taint. You see,
+though I am a eugenist I am not an extremist.”
+
+He paused, then resumed argumentatively: “Then there are other
+questions, too, like that of genius with its close relation to manic
+depressive insanity. Also, there is decrease enough in the birth rate,
+without adding an excuse for it. No, that a young man like Atherton
+should take the subject seriously, instead of spending his time in wild
+dissipation, like his father, is certainly creditable, argues in itself
+that there still must exist some strength in his stock.
+
+“And, of course,” he continued warmly, “when I say that weakness in a
+trait—not in all traits, by any means—should marry strength and that
+strength may marry weakness, I don’t mean that all matches should be
+like that. If we are too strict we may prohibit practically all
+marriages. In Atherton’s case, as in many another, I felt that I should
+interpret the rule as sanely as possible.”
+
+“Strength should marry strength, and weakness should never marry,”
+persisted Maude Schofield. “Nothing short of that will satisfy the true
+eugenist.”
+
+“Theoretically,” objected Crafts. “But Atherton was going to marry,
+anyhow. The only thing for me to do was to lay down a rule which he
+might follow safely. Besides, any other rule meant sure disaster.”
+
+“It was the only rule with half a chance of being followed and at any
+rate,” drawled Kennedy, as the eugenists wrangled, “what difference
+does it make in this case? As nearly as I can make out it is Mrs.
+Atherton herself, not Atherton, who is ill.”
+
+Maude Schofield had risen to return to supervising a clerk who needed
+help. She left us, still unconvinced.
+
+“That is a very clever girl,” remarked Kennedy as she shut the door and
+he scanned Dr. Crafts’ face dosely.
+
+“Very,” assented the Doctor.
+
+“The Schofields come of good stock?” hazarded Kennedy.
+
+“Very,” assented Dr. Crafts again.
+
+Evidently he did not care to talk about individual cases, and I felt
+that the rule was a safe one, to prevent Eugenics from becoming Gossip.
+Kennedy thanked him for his courtesy, and we left apparently on the
+best of terms both with Crafts and his assistant.
+
+
+
+
+CHAPTER XXXIII
+THE SEX CONTROL
+
+
+I did not see Kennedy again that day until late in the afternoon, when
+he came into the laboratory carrying a small package.
+
+“Theory is one thing, practice is another,” he remarked, as he threw
+his hat and coat into a chair.
+
+“Which means—in this case?” I prompted.
+
+“Why, I have just seen Atherton. Of course I didn’t repeat our
+conversation of this morning, and I’m glad I didn’t. He almost makes me
+think you are right, Walter. He’s obsessed by the fear of Burroughs.
+Why, he even told me that Burroughs had gone so far as to take a leaf
+out of his book, so to speak, get in touch with the Eugenics Bureau as
+if to follow his footsteps, but really to pump them about Atherton
+himself. Atherton says it’s all Burroughs’ plan to break his will and
+that the fellow has even gone so far as to cultivate the acquaintance
+of Maude Schofield, knowing that he will get no sympathy from Crafts.”
+
+“First it was Edith Atherton, now it is Maude Schofield that he hitches
+up with Burroughs,” I commented. “Seems to me that I have heard that
+one of the first signs of insanity is belief that everyone about the
+victim is conspiring against him. I haven’t any love for any of
+them—but I must be fair.”
+
+“Well,” said Kennedy, unwrapping the package, “there _is_ this much to
+it. Atherton says Burroughs and Maude Schofield have been seen together
+more than once—and not at intellectual gatherings either. Burroughs is
+a fascinating fellow to a woman, if he wants to be, and the Schofields
+are at least the social equals of the Burroughs. Besides,” he added,
+“in spite of eugenics, feminism, and all the rest—sex, like murder,
+will out. There’s no use having any false ideas about _that_. Atherton
+may see red—but, then, he was quite excited.”
+
+“Over what?” I asked, perplexed more than ever at the turn of events.
+
+“He called me up in the first place. ‘Can’t you do something?’ he
+implored. ‘Eugenia is getting worse all the time.’ She is, too. I saw
+her for a moment, and she was even more vacant than yesterday.”
+
+The thought of the poor girl in the big house somehow brought over me
+again my first impression of Poe’s story.
+
+Kennedy had unwrapped the package which proved to be the instrument he
+had left in the closet at Atherton’s. It was, as I had observed, like
+an ordinary wax cylinder phonograph record.
+
+“You see,” explained Kennedy, “it is nothing more than a successful
+application at last of, say, one of those phonographs you have seen in
+offices for taking dictation, placed so that the feebler vibrations of
+the telephone affect it. Let us see what we have here.”
+
+He had attached the cylinder to an ordinary phonograph, and after a
+number of routine calls had been run off, he came to this, in voices
+which we could only guess at but not recognize, for no names were used.
+
+“How is she to-day?”
+
+“Not much changed—perhaps not so well.”
+
+“It’s all right, though. That is natural. It is working well. I think
+you might increase the dose, one tablet.”
+
+“You’re sure it is all right?” (with anxiety).
+
+“Oh, positively—it has been done in Europe.”
+
+“I hope so. It must be a boy—and an _Atherton_.”
+
+“Never fear.”
+
+That was all. Who was it? The voices were unfamiliar to me, especially
+when repeated mechanically. Besides they may have been disguised. At
+any rate we had learned something. Some one was trying to control the
+sex of the expected Atherton heir. But that was about all. Who it was,
+we knew no better, apparently, than before.
+
+Kennedy did not seem to care much, however. Quickly he got Quincy
+Atherton on the wire and arranged for Atherton to have Dr. Crafts meet
+us at the house at eight o’clock that night, with Maude Schofield. Then
+he asked that Burroughs Atherton be there, and of course, Edith and
+Eugenia.
+
+We arrived almost as the clock was striking, Kennedy carrying the
+phonograph record and another blank record, and a boy tugging along the
+machine itself. Dr. Crafts was the next to appear, expressing surprise
+at meeting us, and I thought a bit annoyed, for he mentioned that it
+had been with reluctance that he had had to give up some work he had
+planned for the evening. Maude Schofield, who came with him, looked
+bored. Knowing that she disapproved of the match with Eugenia, I was
+not surprised. Burroughs arrived, not as late as I had expected, but
+almost insultingly supercilious at finding so many strangers at what
+Atherton had told him was to be a family conference, in order to get
+him to come. Last of all Edith Atherton descended the staircase, the
+personification of dignity, bowing to each with a studied graciousness,
+as if distributing largess, but greeting Burroughs with an air that
+plainly showed how much thicker was blood than water. Eugenia remained
+upstairs, lethargic, almost cataleptic, as Atherton told us when we
+arrived.
+
+“I trust you are not going to keep us long, Quincy,” yawned Burroughs,
+looking ostentatiously at his watch.
+
+“Only long enough for Professor Kennedy to say a few words about
+Eugenia,” replied Atherton nervously, bowing to Kennedy.
+
+Kennedy cleared his throat slowly.
+
+“I don’t know that I have much to say,” began Kennedy, still seated. “I
+suppose Mr. Atherton has told you I have been much interested in the
+peculiar state of health of Mrs. Atherton?”
+
+No one spoke, and he went on easily: “There is something I might say,
+however, about the—er—what I call the chemistry of insanity. Among the
+present wonders of science, as you doubtless know, none stirs the
+imagination so powerfully as the doctrine that at least some forms of
+insanity are the result of chemical changes in the blood. For instance,
+ill temper, intoxication, many things are due to chemical changes in
+the blood acting on the brain.
+
+“Go further back. Take typhoid fever with its delirium, influenza with
+its suicide mania. All due to toxins—poisons. Chemistry—chemistry—all
+of them chemistry.”
+
+Craig had begun carefully so as to win their attention. He had it as he
+went on: “Do we not brew within ourselves poisons which enter the
+circulation and pervade the system? A sudden emotion upsets the
+chemistry of the body. Or poisonous food. Or a drug. It affects many
+things. But we could never have had this chemical theory unless we had
+had physiological chemistry—and some carry it so far as to say that the
+brain secretes thought, just as the liver secretes bile, that thoughts
+are the results of molecular changes.”
+
+“You are, then, a materialist of the most pronounced type,” asserted
+Dr. Crafts.
+
+Kennedy had been reaching over to a table, toying with the phonograph.
+As Crafts spoke he moved a key, and I suspected that it was in order to
+catch the words.
+
+“Not entirely,” he said. “No more than some eugenists.”
+
+“In our field,” put in Maude Schofield, “I might express the thought
+this way—the sociologist has had his day; now it is the biologist, the
+eugenist.”
+
+“That expresses it,” commented Kennedy, still tinkering with the
+record. “Yet it does not mean that because we have new ideas, they
+abolish the old. Often they only explain, amplify, supplement. For
+instance,” he said, looking up at Edith Atherton, “take heredity. Our
+knowledge seems new, but is it? Marriages have always been dictated by
+a sort of eugenics. Society is founded on that.”
+
+“Precisely,” she answered. “The best families have always married into
+the best families. These modern notions simply recognize what the best
+people have always thought—except that it seems to me,” she added with
+a sarcastic flourish, “people of no ancestry are trying to force
+themselves in among their betters.”
+
+“Very true, Edith,” drawled Burroughs, “but we did not have to be
+brought here by Quincy to learn that.”
+
+Quincy Atherton had risen during the discussion and had approached
+Kennedy. Craig continued to finger the phonograph abstractedly, as he
+looked up.
+
+“About this—this insanity theory,” he whispered eagerly. “You think
+that the suspicions I had have been justified?”
+
+I had been watching Kennedy’s hand. As soon as Atherton had started to
+speak, I saw that Craig, as before, had moved the key, evidently
+registering what he said, as he had in the case of the others during
+the discussion.
+
+“One moment, Atherton,” he whispered in reply, “I’m coming to that.
+Now,” he resumed aloud, “there is a disease, or a number of diseases,
+to which my remarks about insanity a while ago might apply very well.
+They have been known for some time to arise from various affections of
+the thyroid glands in the neck. These glands, strange to say, if acted
+on in certain ways can cause degenerations of mind and body, which are
+well known, but in spite of much study are still very little
+understood. For example, there is a definite interrelation between them
+and sex—especially in woman.”
+
+Rapidly he sketched what he had already told me of the thyroid and the
+hormones. “These hormones,” added Kennedy, “are closely related to many
+reactions in the body, such as even the mother’s secretion of milk at
+the proper time and then only. That and many other functions are due to
+the presence and character of these chemical secretions from the
+thyroid and other ductless glands. It is a fascinating study. For we
+know that anything that will upset—reduce or increase—the hormones is a
+matter intimately concerned with health. Such changes,” he said
+earnestly, leaning forward, “might be aimed directly at the very heart
+of what otherwise would be a true eugenic marriage. It is even possible
+that loss of sex itself might be made to follow deep changes of the
+thyroid.”
+
+He stopped a moment. Even if he had accomplished nothing else he had
+struck a note which had caused the Athertons to forget their former
+superciliousness.
+
+“If there is an oversupply of thyroid hormones,” continued Craig, “that
+excess will produce many changes, for instance a condition very much
+like exophthalmic goiter. And,” he said, straightening up, “I find that
+Eugenia Atherton has within her blood an undue proportion of these
+thyroid hormones. Now, is it overfunction of the glands,
+hyper-secretion—or is it something else?”
+
+No one moved as Kennedy skillfully led his disclosure along step by
+step.
+
+“That question,” he began again slowly, shifting his position in the
+chair, “raises in my mind, at least, a question which has often
+occurred to me before. Is it possible for a person, taking advantage of
+the scientific knowledge we have gained, to devise and successfully
+execute a murder without fear of discovery? In other words, can a
+person be removed with that technical nicety of detail which will leave
+no clue and will be set down as something entirely natural, though
+unfortunate?”
+
+It was a terrible idea he was framing, and he dwelt on it so that we
+might accept it at its full value. “As one doctor has said,” he added,
+“although toxicologists and chemists have not always possessed
+infallible tests for practical use, it is at present a pretty certain
+observation that every poison leaves its mark. But then on the other
+hand, students of criminology have said that a skilled physician or
+surgeon is about the only person now capable of carrying out a really
+scientific murder.
+
+“Which is true? It seems to me, at least in the latter case, that the
+very nicety of the handiwork must often serve as a clue in itself. The
+trained hand leaves the peculiar mark characteristic of its training.
+No matter how shrewdly the deed is planned, the execution of it is
+daily becoming a more and more difficult feat, thanks to our increasing
+knowledge of microbiology and pathology.”
+
+He had risen, as he finished the sentence, every eye fixed on him, as
+if he had been a master hypnotist.
+
+“Perhaps,” he said, taking off the cylinder from the phonograph and
+placing on one which I knew was that which had lain in the library
+closet over night, “perhaps some of the things I have said will explain
+or be explained by the record on this cylinder.”
+
+He had started the machine. So magical was the effect on the little
+audience that I am tempted to repeat what I had already heard, but had
+not myself yet been able to explain:
+
+“How is she to-day?”
+
+“Not much changed—perhaps not so well.”
+
+“It’s all right, though. That is natural. It is working well. I think
+you might increase the dose one tablet.”
+
+“You’re sure it is all right?”
+
+“Oh, positively—it has been done in Europe.”
+
+“I hope so. It must be a boy—and an _Atherton_.”
+
+“Never fear.”
+
+No one moved a muscle. If there was anyone in the room guilty of
+playing on the feelings and the health of an unfortunate woman, that
+person must have had superb control of his own feelings.
+
+“As you know,” resumed Kennedy thoughtfully, “there are and have been
+many theories of sex control. One of the latest, but by no means the
+only one, is that it can be done by use of the extracts of various
+glands administered to the mother. I do not know with what scientific
+authority it was stated, but I do know that some one has recently said
+that adrenalin, derived from the suprarenal glands, induces boys to
+develop—cholin, from the bile of the liver, girls. It makes no
+difference—in this case. There may have been a show of science. But it
+was to cover up a crime. Some one has been administering to Eugenia
+Atherton tablets of thyroid extract—ostensibly to aid her in fulfilling
+the dearest ambition of her soul—to become the mother of a new line of
+Athertons which might bear the same relation to the future of the
+country as the great family of the Edwards mothered by Elizabeth
+Tuttle.”
+
+He was bending over the two phonograph cylinders now, rapidly comparing
+the new one which he had made and that which he had just allowed to
+reel off its astounding revelation.
+
+“When a voice speaks into a phonograph,” he said, half to himself, “its
+modulations received on the diaphragm are written by a needle point
+upon the surface of a cylinder or disk in a series of fine waving or
+zigzag lines of infinitely varying depth or breadth. Dr. Marage and
+others have been able to distinguish vocal sounds by the naked eye on
+phonograph records. Mr. Edison has studied them with the microscope in
+his world-wide search for the perfect voice.
+
+“In fact, now it is possible to identify voices by the records they
+make, to get at the precise meaning of each slightest variation of the
+lines with mathematical accuracy. They can no more be falsified than
+handwriting can be forged so that modern science cannot detect it or
+than typewriting can be concealed and attributed to another machine.
+The voice is like a finger print, a portrait parlé—unescapable.”
+
+He glanced up, then back again. “This microscope shows me,” he said,
+“that the voices on that cylinder you heard are identical with two on
+this record which I have just made in this room.”
+
+“Walter,” he said, motioning to me, “look.”
+
+I glanced into the eyepiece and saw a series of lines and curves,
+peculiar waves lapping together and making an appearance in some spots
+almost like tooth marks. Although I did not understand the details of
+the thing, I could readily see that by study one might learn as much
+about it as about loops, whorls, and arches on finger tips.
+
+“The upper and lower lines,” he explained, “with long regular waves, on
+that highly magnified section of the record, are formed by the voice
+with no overtones. The three lines in the middle, with rhythmic
+ripples, show the overtones.”
+
+He paused a moment and faced us. “Many a person,” he resumed, “is a
+biotype in whom a full complement of what are called inhibitions never
+develops. That is part of your eugenics. Throughout life, and in spite
+of the best of training, that person reacts now and then to a certain
+stimulus directly. A man stands high; once a year he falls with a
+lethal quantity of alcohol. A woman, brilliant, accomplished, slips
+away and spends a day with a lover as unlike herself as can be
+imagined.
+
+“The voice that interests me most on these records,” he went on,
+emphasizing the words with one of the cylinders which he still held,
+“is that of a person who has been working on the family pride of
+another. That person has persuaded the other to administer to Eugenia
+an extract because ‘it must be a boy and an Atherton.’ That person is a
+high-class defective, born with a criminal instinct, reacting to it in
+an artful way. Thank God, the love of a man whom theoretical eugenics
+condemned, roused us in—”
+
+A cry at the door brought us all to our feet, with hearts thumping as
+if they were bursting.
+
+It was Eugenia Atherton, wild-eyed, erect, staring.
+
+I stood aghast at the vision. Was she really to be the Lady Madeline in
+this fall of the House of Atherton?
+
+“Edith—I—I missed you. I heard voices. Is—is it true—what this
+man—says? Is my—my baby—”
+
+Quincy Atherton leaped forward and caught her as she reeled. Quickly
+Craig threw open a window for air, and as he did so leaned far out and
+blew shrilly on a police whistle.
+
+The young man looked up from Eugenia, over whom he was bending,
+scarcely heeding what else went on about him. Still, there was no trace
+of anger on his face, in spite of the great wrong that had been done
+him. There was room for only one great emotion—only anxiety for the
+poor girl who had suffered so cruelly merely for taking his name.
+
+Kennedy saw the unspoken question in his eyes.
+
+“Eugenia is a pure normal, as Dr. Crafts told you,” he said gently. “A
+few weeks, perhaps only days, of treatment—the thyroid will revert to
+its normal state—and Eugenia Gilman will be the mother of a new house
+of Atherton which may eclipse even the proud record of the founder of
+the old.”
+
+“Who blew the whistle?” demanded a gruff voice at the door, as a tall
+bluecoat puffed past the scandalized butler.
+
+“Arrest that woman,” pointed Kennedy. “She is the poisoner. Either as
+wife of Burroughs, whom she fascinates and controls as she does Edith,
+she planned to break the will of Quincy or, in the other event, to
+administer the fortune as head of the Eugenics Foundation after the
+death of Dr. Crafts, who would have followed Eugenia and Quincy
+Atherton.”
+
+I followed the direction of Kennedy’s accusing finger. Maude
+Schofield’s face betrayed more than even her tongue could have
+confessed.
+
+
+
+
+CHAPTER XXXIV
+THE BILLIONAIRE BABY
+
+
+Coming to us directly as a result of the talk that the Atherton case
+provoked was another that involved the happiness of a wealthy family to
+a no less degree.
+
+“I suppose you have heard of the ‘billionaire baby,’ Morton Hazleton
+III?” asked Kennedy of me one afternoon shortly afterward.
+
+The mere mention of the name conjured up in my mind a picture of the
+lusty two-year-old heir of two fortunes, as the feature articles in the
+_Star_ had described that little scion of wealth—his luxurious nursery,
+his magnificent toys, his own motor car, a trained nurse and a
+detective on guard every hour of the day and night, every possible
+precaution for his health and safety.
+
+“Gad, what a lucky kid!” I exclaimed involuntarily.
+
+“Oh, I don’t know about that,” put in Kennedy. “The fortune may be
+exaggerated. His happiness is, I’m sure.”
+
+He had pulled from his pocketbook a card and handed it to me. It read:
+“Gilbert Butler, American representative, Lloyd’s.”
+
+“Lloyd’s?” I queried. “What has Lloyd’s to do with the billion-dollar
+baby?”
+
+“Very much. The child has been insured with them for some fabulous sum
+against accident, including kidnaping.”
+
+“Yes?” I prompted, “sensing” a story.
+
+“Well, there seem to have been threats of some kind, I understand. Mr.
+Butler has called on me once already to-day to retain my services and
+is going to—ah—there he is again now.”
+
+Kennedy had answered the door buzzer himself, and Mr. Butler, a tall,
+sloping-shouldered Englishman, entered.
+
+“Has anything new developed?” asked Kennedy, introducing me.
+
+“I can’t say,” replied Butler dubiously. “I rather think we have found
+something that may have a bearing on the case. You know Miss Haversham,
+Veronica Haversham?”
+
+“The actress and professional beauty? Yes—at least I have seen her.
+Why?”
+
+“We hear that Morton Hazleton knows her, anyhow,” remarked Butler
+dryly.
+
+“Well?”
+
+“Then you don’t know the gossip?” he cut in. “She is said to be in a
+sanitarium near the city. I’ll have to find that out for you. It’s a
+fast set she has been traveling with lately, including not only
+Hazleton, but Dr. Maudsley, the Hazleton physician, and one or two
+others, who if they were poorer might be called desperate characters.”
+
+“Does Mrs. Hazleton know of—of his reputed intimacy?”
+
+“I can’t say that, either. I presume that she is no fool.”
+
+Morton Hazleton, Jr., I knew, belonged to a rather smart group of young
+men. He had been mentioned in several near-scandals, but as far as I
+knew there had been nothing quite as public and definite as this one.
+
+“Wouldn’t that account for her fears?” I asked.
+
+“Hardly,” replied Butler, shaking his head. “You see, Mrs. Hazleton is
+a nervous wreck, but it’s about the baby, and caused, she says, by her
+fears for its safety. It came to us only in a roundabout way, through a
+servant in the house who keeps us in touch. The curious feature is that
+we can seem to get nothing definite from her about her fears. They may
+be groundless.”
+
+Butler shrugged his shoulders and proceeded, “And they may be
+well-founded. But we prefer to run no chances in a case of this kind.
+The child, you know, is guarded in the house. In his perambulator he is
+doubly guarded, and when he goes out for his airing in the automobile,
+two men, the chauffeur and a detective, are always there, besides his
+nurse, and often his mother or grandmother. Even in the nursery suite
+they have iron shutters which can be pulled down and padlocked at night
+and are constructed so as to give plenty of fresh air even to a
+scientific baby. Master Hazleton was the best sort of risk, we thought.
+But now—we don’t know.”
+
+“You can protect yourselves, though,” suggested Kennedy.
+
+“Yes, we have, under the policy, the right to take certain measures to
+protect ourselves in addition to the precautions taken by the
+Hazletons. We have added our own detective to those already on duty.
+But we—we don’t know what to guard against,” he concluded, perplexed.
+“We’d like to know—that’s all. It’s too big a risk.”
+
+“I may see Mrs. Hazleton?” mused Kennedy.
+
+“Yes. Under the circumstances she can scarcely refuse to see anyone we
+send. I’ve arranged already for you to meet her within an hour. Is that
+all right?”
+
+“Certainly.”
+
+The Hazleton home in winter in the city was uptown, facing the river.
+The large grounds adjoining made the Hazletons quite independent of the
+daily infant parade which one sees along Riverside Drive.
+
+As we entered the grounds we could almost feel the very atmosphere on
+guard. We did not see the little subject of so much concern, but I
+remembered his much heralded advent, when his grandparents had settled
+a cold million on him, just as a reward for coming into the world.
+Evidently, Morton, Sr., had hoped that Morton, Jr., would calm down,
+now that there was a third generation to consider. It seemed that he
+had not. I wondered if that had really been the occasion of the threats
+or whatever it was that had caused Mrs. Hazleton’s fears, and whether
+Veronica Haversham or any of the fast set around her had had anything
+to do with it.
+
+Millicent Hazleton was a very pretty little woman, in whom one saw
+instinctively the artistic temperament. She had been an actress, too,
+when young Morton Hazleton married her, and at first, at least, they
+had seemed very devoted to each other.
+
+We were admitted to see her in her own library, a tastefully furnished
+room on the second floor of the house, facing a garden at the side.
+
+“Mrs. Hazleton,” began Butler, smoothing the way for us, “of course you
+realize that we are working in your interests. Professor Kennedy,
+therefore, in a sense, represents both of us.”
+
+“I am quite sure I shall be delighted to help you,” she said with an
+absent expression, though not ungraciously.
+
+Butler, having introduced us, courteously withdrew. “I leave this
+entirely in your hands,” he said, as he excused himself. “If you want
+me to do anything more, call on me.”
+
+I must say that I was much surprised at the way she had received us.
+Was there in it, I wondered, an element of fear lest if she refused to
+talk suspicion might grow even greater? One could see anxiety plainly
+enough on her face, as she waited for Kennedy to begin.
+
+A few moments of general conversation then followed.
+
+“Just what is it you fear?” he asked, after having gradually led around
+to the subject. “Have there been any threatening letters?”
+
+“N-no,” she hesitated, “at least nothing—definite.”
+
+“Gossip?” he hinted.
+
+“No.” She said it so positively that I fancied it might be taken for a
+plain “Yes.”
+
+“Then what is it?” he asked, very deferentially, but firmly.
+
+She had been looking out at the garden. “You couldn’t understand,” she
+remarked. “No detective—” she stopped.
+
+“You may be sure, Mrs. Hazleton, that I have not come here
+unnecessarily to intrude,” he reassured her. “It is exactly as Mr.
+Butler put it. We—want to help you.”
+
+I fancied there seemed to be something compelling about his manner. It
+was at once sympathetic and persuasive. Quite evidently he was taking
+pains to break down the prejudice in her mind which she had already
+shown toward the ordinary detective.
+
+“You would think me crazy,” she remarked slowly. “But it is just a—a
+dream—just dreams.”
+
+I don’t think she had intended to say anything, for she stopped short
+and looked at him quickly as if to make sure whether he could
+understand. As for myself, I must say I felt a little skeptical. To my
+surprise, Kennedy seemed to take the statement at its face value.
+
+“Ah,” he remarked, “an anxiety dream? You will pardon me, Mrs.
+Hazleton, but before we go further let me tell you frankly that I am
+much more than an ordinary detective. If you will permit me, I should
+rather have you think of me as a psychologist, a specialist, one who
+has come to set your mind at rest rather than to worm things from you
+by devious methods against which you have to be on guard. It is just
+for such an unusual case as yours that Mr. Butler has called me in. By
+the way, as our interview may last a few minutes, would you mind
+sitting down? I think you’ll find it easier to talk if you can get your
+mind perfectly at rest, and for the moment trust to the nurse and the
+detectives who are guarding the garden, I am sure, perfectly.”
+
+She had been standing by the window during the interview and was quite
+evidently growing more and more nervous. With a bow Kennedy placed her
+at her ease on a chaise lounge.
+
+“Now,” he continued, standing near her, but out of sight, “you must try
+to remain free from all external influences and impressions. Don’t
+move. Avoid every use of a muscle. Don’t let anything distract you.
+Just concentrate your attention on your psychic activities. Don’t
+suppress one idea as unimportant, irrelevant, or nonsensical. Simply
+tell me what occurs to you in connection with the dreams—everything,”
+emphasized Craig.
+
+I could not help feeling surprised to find that she accepted Kennedy’s
+deferential commands, for after all that was what they amounted to.
+Almost I felt that she was turning to him for help, that he had broken
+down some barrier to her confidence. He seemed to exert a sort of
+hypnotic influence over her.
+
+“I have had cases before which involved dreams,” he was saying quietly
+and reassuringly. “Believe me, I do not share the world’s opinion that
+dreams are nothing. Nor yet do I believe in them superstitiously. I can
+readily understand how a dream can play a mighty part in shaping the
+feelings of a high-tensioned woman. Might I ask exactly what it is you
+fear in your dreams?”
+
+She sank her head back in the cushions, and for a moment closed her
+eyes, half in weariness, half in tacit obedience to him. “Oh, I have
+such horrible dreams,” she said at length, “full of anxiety and fear
+for Morton and little Morton. I can’t explain it. But they are so
+horrible.”
+
+Kennedy said nothing. She was talking freely at last.
+
+“Only last night,” she went on, “I dreamt that Morton was dead. I could
+see the funeral, all the preparations, and the procession. It seemed
+that in the crowd there was a woman. I could not see her face, but she
+had fallen down and the crowd was around her. Then Dr. Maudsley
+appeared. Then all of a sudden the dream changed. I thought I was on
+the sand, at the seashore, or perhaps a lake. I was with Junior and it
+seemed as if he were wading in the water, his head bobbing up and down
+in the waves. It was like a desert, too—the sand. I turned, and there
+was a lion behind me. I did not seem to be afraid of him, although I
+was so close that I could almost feel his shaggy mane. Yet I feared
+that he might bite Junior. The next I knew I was running with the child
+in my arms. I escaped—and—oh, the relief!”
+
+She sank back, half exhausted, half terrified still by the
+recollection.
+
+“In your dream when Dr. Maudsley appeared,” asked Kennedy, evidently
+interested in filling in the gap, “what did he do?”
+
+“Do?” she repeated. “In the dream? Nothing.”
+
+“Are you sure?” he asked, shooting a quick glance at her.
+
+“Yes. That part of the dream became indistinct. I’m sure he did
+nothing, except shoulder through the crowd. I think he had just
+entered. Then that part of the dream seemed to end and the second part
+began.”
+
+Piece by piece Kennedy went over it, putting it together as if it were
+a mosaic.
+
+“Now, the woman. You say her face was hidden?”
+
+She hesitated. “N—no. I saw it. But it was no one I knew.”
+
+Kennedy did not dwell on the contradiction, but added, “And the crowd?”
+
+“Strangers, too.”
+
+“Dr. Maudsley is your family physician?” he questioned.
+
+“Yes.”
+
+“Did he call—er—yesterday?”
+
+“He calls every day to supervise the nurse who has Junior in charge.”
+
+“Could one always be true to oneself in the face of any temptation?” he
+asked suddenly.
+
+It was a bold question. Yet such had been the gradual manner of his
+leading up to it that, before she knew it, she had answered quite
+frankly, “Yes—if one always thought of home and her child, I cannot see
+how one could help controlling herself.”
+
+She seemed to catch her breath, almost as though the words had escaped
+her before she knew it.
+
+“Is there anything besides your dream that alarms you,” he asked,
+changing the subject quickly, “any suspicion of—say the servants?”
+
+“No,” she said, watching him now. “But some time ago we caught a
+burglar upstairs here. He managed to escape. That has made me nervous.
+I didn’t think it was possible.”
+
+“Anything else?”
+
+“No,” she said positively, this time on her guard.
+
+Kennedy saw that she had made up her mind to say no more.
+
+“Mrs. Hazleton,” he said, rising. “I can hardly thank you too much for
+the manner in which you have met my questions. It will make it much
+easier for me to quiet your fears. And if anything else occurs to you,
+you may rest assured I shall violate no confidences in your telling
+me.”
+
+I could not help the feeling, however, that there was just a little air
+of relief on her face as we left.
+
+
+
+
+CHAPTER XXXV
+THE PSYCHANALYSIS
+
+
+“H-m,” mused Kennedy as we walked along after leaving the house. “There
+were several ‘complexes,’ as they are called, there—the most
+interesting and important being the erotic, as usual. Now, take the
+lion in the dream, with his mane. That, I suspect, was Dr. Maudsley. If
+you are acquainted with him, you will recall his heavy, almost tawny
+beard.”
+
+Kennedy seemed to be revolving something in his mind and I did not
+interrupt. I had known him too long to feel that even a dream might not
+have its value with him. Indeed, several times before he had given me
+glimpses into the fascinating possibilities of the new psychology.
+
+“In spite of the work of thousands of years, little progress has been
+made in the scientific understanding of dreams,” he remarked a few
+moments later. “Freud, of Vienna—you recall the name?—has done most, I
+think in that direction.”
+
+I recalled something of the theories of the Freudists, but said
+nothing.
+
+“It is an unpleasant feature of his philosophy,” he went on, “but Freud
+finds the conclusion irresistible that all humanity underneath the
+shell is sensuous and sensual in nature. Practically all dreams betray
+some delight of the senses and sexual dreams are a large proportion.
+There is, according to the theory, always a wish hidden or expressed in
+a dream. The dream is one of three things, the open, the disguised or
+the distorted fulfillment of a wish, sometimes recognized, sometimes
+repressed.
+
+“Anxiety dreams are among the most interesting and important Anxiety
+may originate in psycho-sexual excitement, the repressed libido, as the
+Freudists call it. Neurotic fear has its origin in sexual life and
+corresponds to a libido which has been turned away from its object and
+has not succeeded in being applied. All so-called day dreams of women
+are erotic; of men they are either ambition or love.
+
+“Often dreams, apparently harmless, turn out to be sinister if we take
+pains to interpret them. All have the mark of the beast. For example,
+there was that unknown woman who had fallen down and was surrounded by
+a crowd. If a woman dreams that, it is sexual. It can mean only a
+fallen woman. That is the symbolism. The crowd always denotes a secret.
+
+“Take also the dream of death. If there is no sorrow felt, then there
+is another cause for it. But if there is sorrow, then the dreamer
+really desires death or absence. I expect to have you quarrel with
+that. But read Freud, and remember that in childhood death is
+synonymous with being away. Thus for example, if a girl dreams that her
+mother is dead, perhaps it means only that she wishes her away so that
+she can enjoy some pleasure that her strict parent, by her presence,
+denies.
+
+“Then there was that dream about the baby in the water. That, I think,
+was a dream of birth. You see, I asked her practically to repeat the
+dreams because there were several gaps. At such points one usually
+finds first hesitation, then something that shows one of the main
+complexes. Perhaps the subject grows angry at the discovery.
+
+“Now, from the tangle of the dream thought, I find that she fears that
+her husband is too intimate with another woman, and that perhaps
+unconsciously she has turned to Dr. Maudsley for sympathy. Dr.
+Maudsley, as I said, is not only bearded, but somewhat of a social
+lion. He had called on her the day before. Of such stuff are all dream
+lions when there is no fear. But she shows that she has been guilty of
+no wrongdoing—she escaped, and felt relieved.”
+
+“I’m glad of that,” I put in. “I don’t like these scandals. On the
+_Star_ when I have to report them, I do it always under protest. I
+don’t know what your psychanalysis is going to show in the end, but I
+for one have the greatest sympathy for that poor little woman in the
+big house alone, surrounded by and dependent on servants, while her
+husband is out collecting scandals.”
+
+“Which suggests our next step,” he said, turning the subject. “I hope
+that Butler has found out the retreat of Veronica Haversham.”
+
+We discovered Miss Haversham at last at Dr. Klemm’s sanitarium, up in
+the hills of Westchester County, a delightful place with a reputation
+for its rest cures. Dr. Klemm was an old friend of Kennedy’s, having
+had some connection with the medical school at the University.
+
+She had gone up there rather suddenly, it seemed, to recuperate. At
+least that was what was given out, though there seemed to be much
+mystery about her, and she was taking no treatment as far as was known.
+
+“Who is her physician?” asked Kennedy of Dr. Klemm as we sat in his
+luxurious office.
+
+“A Dr. Maudsley of the city.”
+
+Kennedy glanced quickly at me in time to check an exclamation.
+
+“I wonder if I could see her?”
+
+“Why, of course—if she is willing,” replied Dr. Klemm.
+
+“I will have to have some excuse,” ruminated Kennedy. “Tell her I am a
+specialist in nervous troubles from the city, have been visiting one of
+the other patients, anything.”
+
+Dr. Klemm pulled down a switch on a large oblong oak box on his desk,
+asked for Miss Haversham, and waited a moment.
+
+“What is that?” I asked.
+
+“A vocaphone,” replied Kennedy. “This sanitarium is quite up to date,
+Klemm.”
+
+The doctor nodded and smiled. “Yes, Kennedy,” he replied.
+“Communicating with every suite of rooms we have the vocaphone. I find
+it very convenient to have these microphones, as I suppose you would
+call them, catching your words without talking into them directly as
+you have to do in the telephone and then at the other end emitting the
+words without the use of an earpiece, from the box itself, as if from a
+megaphone horn. Miss Haversham, this is Dr. Klemm. There is a Dr.
+Kennedy here visiting another patient, a specialist from New York. He’d
+like very much to see you if you can spare a few minutes.”
+
+“Tell him to come up.” The voice seemed to come from the vocaphone as
+though she were in the room with us.
+
+Veronica Haversham was indeed wonderful, one of the leading figures in
+the night life of New York, a statuesque brunette of striking beauty,
+though I had heard of often ungovernable temper. Yet there was
+something strange about her face here. It seemed perhaps a little
+yellow, and I am sure that her nose had a peculiar look as if she were
+suffering from an incipient rhinitis. The pupils of her eyes were as
+fine as pin heads, her eyebrows were slightly elevated. Indeed, I felt
+that she had made no mistake in taking a rest if she would preserve the
+beauty which had made her popularity so meteoric.
+
+“Miss Haversham,” began Kennedy, “they tell me that you are suffering
+from nervousness. Perhaps I can help you. At any rate it will do no
+harm to try. I know Dr. Maudsley well, and if he doesn’t approve—well,
+you may throw the treatment into the waste basket.”
+
+“I’m sure I have no reason to refuse,” she said. “What would you
+suggest?”
+
+“Well, first of all, there is a very simple test I’d like to try. You
+won’t find that it bothers you in the least—and if I can’t help you,
+then no harm is done.”
+
+Again I watched Kennedy as he tactfully went through the preparations
+for another kind of psychanalysis, placing Miss Haversham at her ease
+on a davenport in such a way that nothing would distract her attention.
+As she reclined against the leather pillows in the shadow it was not
+difficult to understand the lure by which she held together the little
+coterie of her intimates. One beautiful white arm, bare to the elbow,
+hung carelessly over the edge of the davenport, displaying a plain gold
+bracelet.
+
+“Now,” began Kennedy, on whom I knew the charms of Miss Haversham
+produced a negative effect, although one would never have guessed it
+from his manner, “as I read off from this list of words, I wish that
+you would repeat the first thing, anything,” he emphasized, “that comes
+into your head, no matter how trivial it may seem. Don’t force yourself
+to think. Let your ideas flow naturally. It depends altogether on your
+paying attention to the words and answering as quickly as you
+can—remember, the first word that comes into your mind. It is easy to
+do. We’ll call it a game,” he reassured.
+
+Kennedy handed a copy of the list to me to record the answers. There
+must have been some fifty words, apparently senseless, chosen at
+random, it seemed. They were:
+
+head to dance salt white lie
+green sick new child to fear
+water pride to pray sad stork
+to sing ink money to marry false
+death angry foolish dear anxiety
+long needle despise to quarrel to kiss
+ship voyage finger old bride
+to pay to sin expensive family pure
+window bread to fall friend ridicule
+cold rich unjust luck to sleep
+
+“The Jung association word test is part of the Freud psychanalysis,
+also,” he whispered to me, “You remember we tried something based on
+the same idea once before?”
+
+I nodded. I had heard of the thing in connection with blood-pressure
+tests, but not this way.
+
+Kennedy called out the first word, “Head,” while in his hand he held a
+stop watch which registered to one-fifth of a second.
+
+Quickly she replied, “Ache,” with an involuntary movement of her hand
+toward her beautiful forehead.
+
+“Good,” exclaimed Kennedy. “You seem to grasp the idea better than most
+of my patients.”
+
+I had recorded the answer, he the time, and we found out, I recall
+afterward, that the time averaged something like two and two-fifths
+seconds.
+
+I thought her reply to the second word, “green,” was curious. It came
+quickly, “Envy.”
+
+However, I shall not attempt to give all the replies, but merely some
+of the most significant. There did not seem to be any hesitation about
+most of the words, but whenever Kennedy tried to question her about a
+word that seemed to him interesting she made either evasive or
+hesitating answers, until it became evident that in the back of her
+head was some idea which she was repressing and concealing from us,
+something that she set off with a mental “No Thoroughfare.”
+
+He had finished going through the list, and Kennedy was now studying
+over the answers and comparing the time records.
+
+“Now,” he said at length, running his eye over the words again, “I want
+to repeat the performance. Try to remember and duplicate your first
+replies,” he said.
+
+Again we went through what at first had seemed to me to be a solemn
+farce, but which I began to see was quite important. Sometimes she
+would repeat the answer exactly as before. At other times a new word
+would occur to her. Kennedy was keen to note all the differences in the
+two lists.
+
+One which I recall because the incident made an impression on me had to
+do with the trio, “Death—life—inevitable.”
+
+“Why that?” he asked casually.
+
+“Haven’t you ever heard the saying, ‘One should let nothing which one
+can have escape, even if a little wrong is done; no opportunity should
+be missed; life is so short, death inevitable’?”
+
+There were several others which to Kennedy seemed more important, but
+long after we had finished I pondered this answer. Was that her
+philosophy of life? Undoubtedly she would never have remembered the
+phrase if it had not been so, at least in a measure.
+
+She had begun to show signs of weariness, and Kennedy quickly brought
+the conversation around to subjects of apparently a general nature, but
+skillfully contrived so as to lead the way along lines her answers had
+indicated.
+
+Kennedy had risen to go, still chatting. Almost unintentionally he
+picked up from a dressing table a bottle of white tablets, without a
+label, shaking it to emphasize an entirely, and I believe purposely,
+irrelevant remark.
+
+“By the way,” he said, breaking off naturally, “what is that?”
+
+“Only something Dr. Maudsley had prescribed for me,” she answered
+quickly.
+
+As he replaced the bottle and went on with the thread of the
+conversation, I saw that in shaking the bottle he had abstracted a
+couple of the tablets before she realized it. “I can’t tell you just
+what to do without thinking the case over,” he concluded, rising to go.
+“Yours is a peculiar case, Miss Haversham, baffling. I’ll have to study
+it over, perhaps ask Dr. Maudsley If I may see you again. Meanwhile, I
+am sure what he is doing is the correct thing.”
+
+Inasmuch as she had said nothing about what Dr. Maudsley was doing, I
+wondered whether there was not just a trace of suspicion in her glance
+at him from under her long dark lashes.
+
+“I can’t see that you have done anything,” she remarked pointedly. “But
+then doctors are queer—queer.”
+
+That parting shot also had in it, for me, something to ponder over. In
+fact I began to wonder if she might not be a great deal more clever
+than even Kennedy gave her credit for being, whether she might not have
+submitted to his tests for pure love of pulling the wool over his eyes.
+
+Downstairs again, Kennedy paused only long enough to speak a few words
+with his friend Dr. Klemm.
+
+“I suppose you have no idea what Dr. Maudsley has prescribed for her?”
+he asked carelessly.
+
+“Nothing, as far as I know, except rest and simple food.”
+
+He seemed to hesitate, then he said under his voice, “I suppose you
+know that she is a regular dope fiend, seasons her cigarettes with
+opium, and all that.”
+
+“I guessed as much,” remarked Kennedy, “but how does she get it here?”
+
+“She doesn’t.”
+
+“I see,” remarked Craig, apparently weighing now the man before him. At
+length he seemed to decide to risk something.
+
+“Klemm,” he said, “I wish you would do something for me. I see you have
+the vocaphone here. Now if—say Hazleton—should call—will you listen in
+on that vocaphone for me?” Dr. Klemm looked squarely at him.
+
+“Kennedy,” he said, “it’s unprofessional, but—-”
+
+“So it is to let her be doped up under guise of a cure.”
+
+“What?” he asked, startled. “She’s getting the stuff now?”
+
+“No, I didn’t say she was getting opium, or from anyone here. All the
+same, if you would just keep an ear open—-”
+
+“It’s unprofessional, but—you’d not ask it without a good reason. I’ll
+try.”
+
+It was very late when we got back to the city and we dined at an uptown
+restaurant which we had almost to ourselves.
+
+Kennedy had placed the little whitish tablets in a small paper packet
+for safe keeping. As we waited for our order he drew one from his
+pocket, and after looking at it a moment crushed it to a powder in the
+paper.
+
+“What is it?” I asked curiously. “Cocaine?”
+
+“No,” he said, shaking his head doubtfully.
+
+He had tried to dissolve a little of the powder in some water from the
+glass before him, but it would not dissolve.
+
+As he continued to look at it his eye fell on the cut-glass vinegar
+cruet before us. It was full of the white vinegar.
+
+“Really acetic acid,” he remarked, pouring out a little.
+
+The white powder dissolved.
+
+For several minutes he continued looking at the stuff.
+
+“That, I think,” he remarked finally, “is heroin.”
+
+“More ‘happy dust’?” I replied with added interest now, thinking of our
+previous case. “Is the habit so extensive?”
+
+“Yes,” he replied, “the habit is comparatively new, although in Paris,
+I believe, they call the drug fiends, ‘heroinomaniacs.’ It is, as I
+told you before, a derivative of morphine. Its scientific name is
+diacetyl-morphin. It is New York’s newest peril, one of the most
+dangerous drugs yet. Thousands are slaves to it, although its sale is
+supposedly restricted. It is rotting the heart out of the Tenderloin.
+Did you notice Veronica Haversham’s yellowish whiteness, her down-drawn
+mouth, elevated eyebrows, and contracted eyes? She may have taken it up
+to escape other drugs. Some people have—and have just got a new habit.
+It can be taken hypodermically, or in a tablet, or by powdering the
+tablet to a white crystalline powder and snuffing up the nose. That’s
+the way she takes it. It produces rhinitis of the nasal passages, which
+I see you observed, but did not understand. It has a more profound
+effect than morphine, and is ten times as powerful as codeine. And one
+of the worst features is that so many people start with it, thinking it
+is as harmless as it has been advertised. I wouldn’t be surprised if
+she used from seventy-five to a hundred one-twelfth grain tablets a
+day. Some of them do, you know.”
+
+“And Dr. Maudsley,” I asked quickly, “do you think it is through him or
+in spite of him?”
+
+“That’s what I’d like to know. About those words,” he continued, “what
+did you make of the list and the answers?”
+
+I had made nothing and said so, rather quickly.
+
+“Those,” he explained, “were words selected and arranged to strike
+almost all the common complexes in analyzing and diagnosing. You’d
+think any intelligent person could give a fluent answer to them,
+perhaps a misleading answer. But try it yourself, Walter. You’ll find
+you can’t. You may start all right, but not all the words will be
+reacted to in the same time or with the same smoothness and ease. Yet,
+like the expressions of a dream, they often seem senseless. But they
+have a meaning as soon as they are ‘psychanalyzed.’ All the mistakes in
+answering the second time, for example, have a reason, if we can only
+get at it. They are not arbitrary answers, but betray the inmost
+subconscious thoughts, those things marked, split off from
+consciousness and repressed into the unconscious. Associations, like
+dreams, never lie. You may try to conceal the emotions and unconscious
+actions, but you can’t.”
+
+I listened, fascinated by Kennedy’s explanation.
+
+“Anyone can see that that woman has something on her mind besides the
+heroin habit. It may be that she is trying to shake the habit off in
+order to do it; it may be that she seeks relief from her thoughts by
+refuge in the habit; and it may be that some one has purposely caused
+her to contract this new habit in the guise of throwing off an old. The
+only way by which to find out is to study the case.”
+
+He paused. He had me keenly on edge, but I knew that he was not yet in
+a position to answer his queries positively.
+
+“Now I found,” he went on, “that the religious complexes were extremely
+few; as I expected the erotic were many. If you will look over the
+three lists you will find something queer about every such word as,
+‘child, ‘to marry,’ ‘bride,’ ‘to lie,’ ‘stork,’ and so on. We’re on the
+right track. That woman does know something about that child.”
+
+“My eye catches the words ‘to sin,’ ‘to fall,’ ‘pure,’ and others,” I
+remarked, glancing over the list.
+
+“Yes, there’s something there, too. I got the hint for the drug from
+her hesitation over ‘needle’ and ‘white.’ But the main complex has to
+do with words relating to that child and to love. In short, I think we
+are going to find it to be the reverse of the rule of the French, that
+it will be a case of ‘cherchez l’homme.’”
+
+Early the next day Kennedy, after a night of studying over the case,
+journeyed up to the sanitarium again. We found Dr. Klemm eager to meet
+us.
+
+“What is it?” asked Kennedy, equally eager.
+
+“I overheard some surprising things over the vocaphone,” he hastened.
+“Hazleton called. Why, there must have been some wild orgies in that
+precious set of theirs, and, would you believe it, many of them seem to
+have been at what Dr. Maudsley calls his ‘stable studio,’ a den he has
+fixed up artistically over his garage on a side street.”
+
+“Indeed?”
+
+“I couldn’t get it all, but I did hear her repeating over and over to
+Hazleton, ‘Aren’t you all mine? Aren’t you all mine?’ There must be
+some vague jealousy lurking in the heart of that ardent woman. I can’t
+figure it out.”
+
+“I’d like to see her again,” remarked Kennedy. “Will you ask her if I
+may?”
+
+
+
+
+CHAPTER XXXVI
+THE ENDS OF JUSTICE
+
+
+A few minutes later we were in the sitting room of her suite. She
+received us rather ungraciously, I thought.
+
+“Do you feel any better?” asked Kennedy.
+
+“No,” she replied curtly. “Excuse me for a moment. I wish to see that
+maid of mine. Clarisse!”
+
+She had hardly left the room when Kennedy was on his feet. The bottle
+of white tablets, nearly empty, was still on the table. I saw him take
+some very fine white powder and dust it quickly over the bottle. It
+seemed to adhere, and from his pocket he quickly drew a piece of what
+seemed to be specially prepared paper, laid it over the bottle where
+the powder adhered, fitting it over the curves. He withdrew it quickly,
+for outside we heard her light step, returning. I am sure she either
+saw or suspected that Kennedy had been touching the bottle of tablets,
+for there was a look of startled fear on her face.
+
+“Then you do not feel like continuing the tests we abandoned last
+night?” asked Kennedy, apparently not noticing her look.
+
+“No, I do not,” she almost snapped. “You—you are detectives. Mrs.
+Hazleton has sent you.”
+
+“Indeed, Mrs. Hazleton has not sent us,” insisted Kennedy, never for an
+instant showing his surprise at her mention of the name.
+
+“You are. You can tell her, you can tell everybody. I’ll tell—I’ll tell
+myself. I won’t wait. That child is mine—mine—not hers. Now—go!”
+
+Veronica Haversham on the stage never towered in a fit of passion as
+she did now in real life, as her ungovernable feelings broke forth
+tempestuously on us.
+
+I was astounded, bewildered at the revelation, the possibilities in
+those simple words, “The child is mine.” For a moment I was stunned.
+Then as the full meaning dawned on me I wondered in a flood of
+consciousness whether it was true. Was it the product of her
+drug-disordered brain? Had her desperate love for Hazleton produced a
+hallucination?
+
+Kennedy, silent, saw that the case demanded quick action. I shall never
+forget the breathless ride down from the sanitarium to the Hazleton
+house on Riverside Drive.
+
+“Mrs. Hazleton,” he cried, as we hurried in, “you will pardon me for
+this unceremonious intrusion, but it is most important. May I trouble
+you to place your fingers on this paper—so?”
+
+He held out to her a piece of the prepared paper. She looked at him
+once, then saw from his face that he was not to be questioned. Almost
+tremulously she did as he said, saying not a word. I wondered whether
+she knew the story of Veronica, or whether so far only hints of it had
+been brought to her.
+
+“Thank you,” he said quickly. “Now, if I may see Morton?”
+
+It was the first time we had seen the baby about whom the rapidly
+thickening events were crowding. He was a perfect specimen of
+well-cared-for, scientific infant.
+
+Kennedy took the little chubby fingers playfully in his own. He seemed
+at once to win the child’s confidence, though he may have violated
+scientific rules. One by one he pressed the little fingers on the
+paper, until little Morton crowed with delight as one little piggy
+after another “went to market.” He had deserted thousands of dollars’
+worth of toys just to play with the simple piece of paper Kennedy had
+brought with him. As I looked at him, I thought of what Kennedy had
+said at the start. Perhaps this innocent child was not to be envied
+after all. I could hardly restrain my excitement over the astounding
+situation which had suddenly developed.
+
+“That will do,” announced Kennedy finally, carelessly folding up the
+paper and slipping it into his pocket. “You must excuse me now.”
+
+“You see,” he explained on the way to the laboratory, “that powder
+adheres to fresh finger prints, taking all the gradations. Then the
+paper with its paraffine and glycerine coating takes off the powder.”
+
+In the laboratory he buried himself in work, with microscope compasses,
+calipers, while I fumed impotently at the window.
+
+“Walter,” he called suddenly, “get Dr. Maudsley on the telephone. Tell
+him to come immediately to the laboratory.”
+
+Meanwhile Kennedy was busy arranging what he had discovered in logical
+order and putting on it the finishing touches.
+
+As Dr. Maudsley entered Kennedy greeted him and began by plunging
+directly into the case in answer to his rather discourteous inquiry as
+to why he had been so hastily summoned.
+
+“Dr. Maudsley,” said Craig, “I have asked you to call alone because,
+while I am on the verge of discovering the truth in an important case
+affecting Morton Hazleton and his wife, I am frankly perplexed as to
+how to go ahead.”
+
+The doctor seemed to shake with excitement as Kennedy proceeded.
+
+“Dr. Maudsley,” Craig added, dropping his voice, “is Morton III the son
+of Millicent Hazleton or not? You were the physician in attendance on
+her at the birth. Is he?”
+
+Maudsley had been watching Kennedy furtively at first, but as he rapped
+out the words I thought the doctor’s eyes would pop out of his head.
+Perspiration in great beads collected on his face.
+
+“P—professor K—Kennedy,” he muttered, frantically rubbing his face and
+lower jaw as if to compose the agitation he could so ill conceal, “let
+me explain.”
+
+“Yes, yes—go on,” urged Kennedy.
+
+“Mrs. Hazleton’s baby was born—dead. I knew how much she and the rest
+of the family had longed for an heir, how much it meant. And
+I—substituted for the dead child a newborn baby from the maternity
+hospital. It—it belonged to Veronica Haversham—then a poor chorus girl.
+I did not intend that she should ever know it. I intended that she
+should think her baby was dead. But in some way she found out. Since
+then she has become a famous beauty, has numbered among her friends
+even Hazleton himself. For nearly two years I have tried to keep her
+from divulging the secret. From time to time hints of it have leaked
+out. I knew that if Hazleton with his infatuation of her were to
+learn—-”
+
+“And Mrs. Hazleton, has she been told?” interrupted Kennedy.
+
+“I have been trying to keep it from her as long as I can, but it has
+been difficult to keep Veronica from telling it. Hazleton himself was
+so wild over her. And she wanted her son as she—-”
+
+“Maudsley,” snapped out Kennedy, slapping down on the table the mass of
+prints and charts which he had hurriedly collected and was studying,
+“you lie! Morton is Millicent Hazleton’s son. The whole story is
+blackmail. I knew it when she told me of her dreams and I suspected
+first some such devilish scheme as yours. Now I know it
+scientifically.”
+
+He turned over the prints.
+
+“I suppose that study of these prints, Maudsley, will convey nothing to
+you. I know that it is usually stated that there are no two sets of
+finger prints in the world that are identical or that can be confused.
+Still, there are certain similarities of finger prints and other
+characteristics, and these similarities have recently been exhaustively
+studied by Bertilion, who has found that there are clear relationships
+sometimes between mother and child in these respects. If Solomon were
+alive, doctor, he would not now have to resort to the expedient to
+which he did when the two women disputed over the right to the living
+child. Modern science is now deciding by exact laboratory methods the
+same problem as he solved by his unique knowledge of feminine
+psychology.
+
+“I saw how this case was tending. Not a moment too soon, I said to
+myself, ‘The hand of the child will tell.’ By the very variations in
+unlike things, such as finger and palm prints, as tabulated and
+arranged by Bertillon after study in thousands of cases, by the very
+loops, whorls, arches and composites, I have proved my case.
+
+“The dominancy, not the identity, of heredity through the infinite
+varieties of finger markings is sometimes very striking. Unique
+patterns in a parent have been repeated with marvelous accuracy in the
+child. I knew that negative results might prove nothing in regard to
+parentage, a caution which it is important to observe. But I was
+prepared to meet even that.
+
+“I would have gone on into other studies, such as Tammasia’s, of
+heredity in the veining of the back of the hands; I would have measured
+the hands, compared the relative proportion of the parts; I would have
+studied them under the X-ray as they are being studied to-day; I would
+have tried the Reichert blood crystal test which is being perfected now
+so that it will tell heredity itself. There is no scientific stone I
+would have left unturned until I had delved at the truth of this
+riddle. Fortunately it was not necessary. Simple finger prints have
+told me enough. And best of all, it has been in time to frustrate that
+devilish scheme you and Veronica Haversham have been slowly unfolding.”
+
+Maudsley crumpled up, as it were, at Kennedy’s denunciation. He seemed
+to shrink toward the door.
+
+“Yes,” cried Kennedy, with extended forefinger, “you may go—for the
+present. Don’t try to run away. You’re watched from this moment on.”
+
+Maudsley had retreated precipitately.
+
+I looked at Kennedy inquiringly. What to do? It was indeed a delicate
+situation, requiring the utmost care to handle. If the story had been
+told to Hazleton, what might he not have already done? He must be found
+first of all if we were to meet the conspiracy of these two.
+
+Kennedy reached quickly for the telephone. “There is one stream of
+scandal that can be dammed at its source,” he remarked, calling a
+number. “Hello. Klemm’s Sanitarium? I’d like to speak with Miss
+Haversham. What—gone? Disappeared? Escaped?”
+
+He hung up the receiver and looked at me blankly. I was speechless.
+
+A thousand ideas flew through our minds at once. Had she perceived the
+import of our last visit and was she now on her way to complete her
+plotted slander of Millicent Hazleton, though it pulled down on herself
+in the end the whole structure?
+
+Hastily Kennedy called Hazleton’s home, Butler, and one after another
+of Hazleton’s favorite clubs. It was not until noon that Butler himself
+found him and came with him, under protest, to the laboratory.
+
+“What is it—what have you found?” cried Butler, his lean form a-quiver
+with suppressed excitement.
+
+Briefly, one fact after another, sparing Hazleton nothing, Kennedy
+poured forth the story, how by hint and innuendo Maudsley had been
+working on Millicent, undermining her, little knowing that he had
+attacked in her a very tower of strength, how Veronica, infatuated by
+him, had infatuated him, had led him on step by step.
+
+Pale and agitated, with nerves unstrung by the life he had been
+leading, Hazleton listened. And as Kennedy hammered one fact after
+another home, he clenched his fists until the nails dug into his very
+palms.
+
+“The scoundrels,” he ground out, as Kennedy finished by painting the
+picture of the brave little broken-hearted woman fighting off she knew
+not what, and the golden-haired, innocent baby stretching out his arms
+in glee at the very chance to prove that he was what he was. “The
+scoundrels—take me to Maudsley now. I must see Maudsley. Quick!”
+
+As we pulled up before the door of the reconstructed stable-studio,
+Kennedy jumped out. The door was unlocked. Up the broad flight of
+stairs, Hazleton went two at a time. We followed him closely.
+
+Lying on the divan in the room that had been the scene of so many
+orgies, locked in each other’s arms, were two figures—Veronica
+Haversham and Dr. Maudsley.
+
+She must have gone there directly after our visit to Dr. Klemm’s, must
+have been waiting for him when he returned with his story of the
+exposure to answer her fears of us as Mrs. Hazleton’s detectives. In a
+frenzy of intoxication she must have flung her arms blindly about him
+in a last wild embrace.
+
+Hazleton looked, aghast.
+
+He leaned over and took her arm. Before he could frame the name,
+“Veronica!” he had recoiled.
+
+The two were cold and rigid.
+
+“An overdose of heroin this time,” muttered Kennedy.
+
+My head was in a whirl.
+
+Hazleton stared blankly at the two figures abjectly lying before him,
+as the truth burned itself indelibly into his soul. He covered his face
+with his hands. And still he saw it all.
+
+Craig said nothing. He was content to let what he had shown work in the
+man’s mind.
+
+“For the sake of—that baby—would she—would she forgive?” asked
+Hazleton, turning desperately toward Kennedy.
+
+Deliberately Kennedy faced him, not as scientist and millionaire, but
+as man and man.
+
+“From my psychanalysis,” he said slowly, “I should say that it IS
+within your power, in time, to change those dreams.”
+
+Hazleton grasped Kennedy’s hand before he knew it.
+
+“Kennedy—home—quick. This is the first manful impulse I have had for
+two years. And, Jameson—you’ll tone down that part of it in the
+newspapers that Junior—might read—when he grows up?”

+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of
+computers including obsolete, old, middle-aged and new computers. It
+exists because of the efforts of hundreds of volunteers and donations
+from people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future
+generations. To learn more about the Project Gutenberg Literary
+Archive Foundation and how your efforts and donations can help, see
+Sections 3 and 4 and the Foundation information page at
+www.gutenberg.org
+
+Section 3. Information about the Project Gutenberg Literary
+Archive Foundation

+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Contributions to the Project Gutenberg Literary

+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without
+widespread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine-readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To SEND
+DONATIONS or determine the status of compliance for any particular
+state visit www.gutenberg.org/donate
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations. To
+donate, please visit: www.gutenberg.org/donate
+
+Section 5. General Information About Project Gutenberg-tm electronic works
+
+Professor Michael S. Hart was the originator of the Project
+Gutenberg-tm concept of a library of electronic works that could be
+freely shared with anyone. For forty years, he produced and
+distributed Project Gutenberg-tm eBooks with only a loose network of
+volunteer support.
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as not protected by copyright in
+the U.S. unless a copyright notice is included. Thus, we do not
+necessarily keep eBooks in compliance with any particular paper
+edition.
+
+Most people start at our website which has the main PG search
+facility: www.gutenberg.org
+
+This website includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.

+<h2><a name="chap00"></a>INTRODUCTION</h2>
+
+<p>
+As I look back now on the sensational events of the past months since the great
+European War began, it seems to me as if there had never been a period in Craig
+Kennedy’s life more replete with thrilling adventures than this.
+</p>
+
+<p>
+In fact, scarcely had one mysterious event been straightened out from the
+tangled skein, when another, even more baffling, crowded on its very heels.
+</p>
+
+<p>
+As was to have been expected with us in America, not all of these remarkable
+experiences grew either directly or indirectly out of the war, but there were
+several that did, and they proved to be only the beginning of a succession of
+events which kept me busy chronicling for the <i>Star</i> the exploits of my
+capable and versatile friend.
+</p>
+
+<p>
+Altogether, this period of the war was, I am sure, quite the most exciting of
+the many series of episodes through which Craig has been called upon to go. Yet
+he seemed to meet each situation as it arose with a fresh mind, which was
+amazing even to me who have known him so long and so intimately.
+</p>
+
+<p>
+As was naturally to be supposed, also, at such a time, it was not long before
+Craig found himself entangled in the marvelous spy system of the warring
+European nations. These systems revealed their devious and dark ways, ramifying
+as they did tentacle-like even across the ocean in their efforts to gain their
+ends in neutral America. Not only so, but, as I shall some day endeavor to show
+later, when the ban of silence imposed by neutrality is raised after the war,
+many of the horrors of the war were brought home intimately to us.
+</p>
+
+<p>
+I have, after mature consideration, decided that even at present nothing but
+good can come from the publication at least of some part of the strange series
+of adventures through which Kennedy and I have just gone, especially those
+which might, if we had not succeeded, have caused most important changes in
+current history. As for the other adventures, no question can be raised about
+the propriety of their publication.
+</p>
+
+<p>
+At any rate, it came about that early in August, when the war cloud was just
+beginning to loom blackest, Kennedy was unexpectedly called into one of the
+strangest, most dangerous situations in which his peculiar and perilous
+profession had ever involved him.
+</p>

+
+<h2><a name="chap01"></a>CHAPTER I<br/>
+THE WAR TERROR</h2>
+
+<p>
+“I must see Professor Kennedy—where is he?—I must see him, for God’s sake!”
+</p>
+
+<p>
+I was almost carried off my feet by the inrush of a wild-eyed girl, seemingly
+half crazed with excitement, as she cried out Craig’s name.
+</p>
+
+<p>
+Startled by my own involuntary exclamation of surprise which followed the
+vision that shot past me as I opened our door in response to a sudden, sharp
+series of pushes at the buzzer, Kennedy bounded swiftly toward me, and the girl
+almost flung herself upon him.
+</p>
+
+<p>
+“Why, Miss—er—Miss—my dear young lady—what’s the matter?” he stammered,
+catching her by the arm gently.
+</p>
+
+<p>
+As Kennedy forced our strange visitor into a chair, I observed that she was all
+a-tremble. Her teeth fairly chattered. Alternately her nervous, peaceless hands
+clutched at an imaginary something in the air, as if for support, then, finding
+none, she would let her wrists fall supine, while she gazed about with
+quivering lips and wild, restless eyes. Plainly, there was something she
+feared. She was almost over the verge of hysteria.
+</p>
+
+<p>
+She was a striking girl, of medium height and slender form, but it was her face
+that fascinated me, with its delicately molded features, intense unfathomable
+eyes of dark brown, and lips that showed her idealistic, high-strung
+temperament.
+</p>
+
+<p>
+“Please,” he soothed, “get yourself together, please—try! What is the matter?”
+</p>
+
+<p>
+She looked about, as if she feared that the very walls had eyes and ears. Yet
+there seemed to be something bursting from her lips that she could not
+restrain.
+</p>
+
+<p>
+“My life,” she cried wildly, “my life is at stake. Oh—help me, help me! Unless
+I commit a murder to-night, I shall be killed myself!”
+</p>
+
+<p>
+The words sounded so doubly strange from a girl of her evident refinement that
+I watched her narrowly, not sure yet but that we had a plain case of insanity
+to deal with.
+</p>
+
+<p>
+“A murder?” repeated Kennedy incredulously. “<i>You</i> commit a murder?”
+</p>
+
+<p>
+Her eyes rested on him, as if fascinated, but she did not flinch as she replied
+desperately, “Yes—Baron Kreiger—you know, the German diplomat and financier,
+who is in America raising money and arousing sympathy with his country.”
+</p>
+
+<p>
+“Baron Kreiger!” exclaimed Kennedy in surprise, looking at her more keenly.
+</p>
+
+<p>
+We had not met the Baron, but we had heard much about him, young, handsome, of
+an old family, trusted already in spite of his youth by many of the more
+advanced of old world financial and political leaders, one who had made a most
+favorable impression on democratic America at a time when such impressions were
+valuable.
+</p>
+
+<p>
+Glancing from one of us to the other, she seemed suddenly, with a great effort,
+to recollect herself, for she reached into her chatelaine and pulled out a card
+from a case.
+</p>
+
+<p>
+It read simply, “Miss Paula Lowe.”
+</p>
+
+<p>
+“Yes,” she replied, more calmly now to Kennedy’s repetition of the Baron’s
+name, “you see, I belong to a secret group.” She appeared to hesitate, then
+suddenly added, “I am an anarchist.”
+</p>
+
+<p>
+She watched the effect of her confession and, finding the look on Kennedy’s
+face encouraging rather than shocked, went on breathlessly: “We are fighting
+war with war—this iron-bound organization of men and women. We have pledged
+ourselves to exterminate all kings, emperors and rulers, ministers of war,
+generals—but first of all the financiers who lend money that makes war
+possible.”
+</p>
+
+<p>
+She paused, her eyes gleaming momentarily with something like the militant
+enthusiasm that must have enlisted her in the paradoxical war against war.
+</p>
+
+<p>
+“We are at least going to make another war impossible!” she exclaimed, for the
+moment evidently forgetting herself.
+</p>
+
+<p>
+“And your plan?” prompted Kennedy, in the most matter-of-fact manner, as though
+he were discussing an ordinary campaign for social betterment. “How were you
+to—reach the Baron?”
+</p>
+
+<p>
+“We had a drawing,” she answered with amazing calmness, as if the mere telling
+relieved her pent-up feelings. “Another woman and I were chosen. We knew the
+Baron’s weakness for a pretty face. We planned to become acquainted with
+him—lure him on.”
+</p>
+
+<p>
+Her voice trailed off, as if, the first burst of confidence over, she felt
+something that would lock her secret tighter in her breast.
+</p>
+
+<p>
+A moment later she resumed, now talking rapidly, disconnectedly, giving Kennedy
+no chance to interrupt or guide the conversation.
+</p>
+
+<p>
+“You don’t know, Professor Kennedy,” she began again, “but there are similar
+groups to ours in European countries and the plan is to strike terror and
+consternation everywhere in the world at once. Why, at our headquarters there
+have been drawn up plans and agreements with other groups and there are set
+down the time, place, and manner of all the—the removals.”
+</p>
+
+<p>
+Momentarily she seemed to be carried away by something like the fanaticism of
+the fervor which had at first captured her, even still held her as she recited
+her incredible story.
+</p>
+
+<p>
+“Oh, can’t you understand?” she went on, as if to justify herself. “The
+increase in armies, the frightful implements of slaughter, the total failure of
+the peace propaganda—they have all defied civilization!
+</p>
+
+<p>
+“And then, too, the old, red-blooded emotions of battle have all been
+eliminated by the mechanical conditions of modern warfare in which men and
+women are just so many units, automata. Don’t you see? To fight war with its
+own weapons—that has become the only last resort.”
+</p>
+
+<p>
+Her eager, flushed face betrayed the enthusiasm which had once carried her into
+the “Group,” as she called it. I wondered what had brought her now to us.
+</p>
+
+<p>
+“We are no longer making war against man,” she cried. “We are making war
+against picric acid and electric wires!”
+</p>
+
+<p>
+I confess that I could not help thinking that there was no doubt that to a
+certain type of mind the reasoning might appeal most strongly.
+</p>
+
+<p>
+“And you would do it in war time, too?” asked Kennedy quickly.
+</p>
+
+<p>
+She was ready with an answer. “King George of Greece was killed at the head of
+his troops. Remember Nazim Pasha, too. Such people are easily reached in time
+of peace and in time of war, also, by sympathizers on their own side. That’s
+it, you see—we have followers of all nationalities.”
+</p>
+
+<p>
+She stopped, her burst of enthusiasm spent. A moment later she leaned forward,
+her clean-cut profile showing her more earnest than before. “But, oh, Professor
+Kennedy,” she added, “it is working itself out to be more terrible than war
+itself!”
+</p>
+
+<p>
+“Have any of the plans been carried out yet?” asked Craig, I thought a little
+superciliously, for there had certainly been no such wholesale assassination
+yet as she had hinted at.
+</p>
+
+<p>
+She seemed to catch her breath. “Yes,” she murmured, then checked herself as if
+in fear of saying too much. “That is, I—I think so.”
+</p>
+
+<p>
+I wondered if she were concealing something, perhaps had already had a hand in
+some such enterprise and it had frightened her.
+</p>
+
+<p>
+Kennedy leaned forward, observing the girl’s discomfiture. “Miss Lowe,” he
+said, catching her eye and holding it almost hypnotically, “why have you come
+to see me?”
+</p>
+
+<p>
+The question, pointblank, seemed to startle her. Evidently she had thought to
+tell only as little as necessary, and in her own way. She gave a little nervous
+laugh, as if to pass it off. But Kennedy’s eyes conquered.
+</p>
+
+<p>
+“Oh, can’t you understand yet?” she exclaimed, rising passionately and throwing
+out her arms in appeal. “I was carried away with my hatred of war. I hate it
+yet. But now—the sudden realization of what this compact all means has—well,
+caused something in me to—to snap. I don’t care what oath I have taken. Oh,
+Professor Kennedy, you—you must save him!”
+</p>
+
+<p>
+I looked up at her quickly. What did she mean? At first she had come to be
+saved herself. “You must save him!” she implored.
+</p>
+
+<p>
+Our door buzzer sounded.
+</p>
+
+<p>
+She gazed about with a hunted look, as if she felt that some one had even now
+pursued her and found out.
+</p>
+
+<p>
+“What shall I do?” she whispered. “Where shall I go?”
+</p>
+
+<p>
+“Quick—in here. No one will know,” urged Kennedy, opening the door to his room.
+He paused for an instant, hurriedly. “Tell me—have you and this other woman met
+the Baron yet? How far has it gone?”
+</p>
+
+<p>
+The look she gave him was peculiar. I could not fathom what was going on in her
+mind. But there was no hesitation about her answer. “Yes,” she replied, “I—we
+have met him. He is to come back to New York from Washington to-day—this
+afternoon—to arrange a private loan of five million dollars with some bankers
+secretly. We were to see him to-night—a quiet dinner, after an automobile ride
+up the Hudson—”
+</p>
+
+<p>
+“Both of you?” interrupted Craig.
+</p>
+
+<p>
+“Yes—that—that other woman and myself,” she repeated, with a peculiar catch in
+her voice. “To-night was the time fixed in the drawing for the—”
+</p>
+
+<p>
+The word stuck in her throat. Kennedy understood. “Yes, yes,” he encouraged,
+“but who is the other woman?”
+</p>
+
+<p>
+Before she could reply, the buzzer had sounded again and she had retreated from
+the door. Quickly Kennedy closed it and opened the outside door.
+</p>
+
+<p>
+It was our old friend Burke of the Secret Service.
+</p>
+
+<p>
+Without a word of greeting, a hasty glance seemed to assure him that Kennedy
+and I were alone. He closed the door himself, and, instead of sitting down,
+came close to Craig.
+</p>
+
+<p>
+“Kennedy,” he blurted out in a tone of suppressed excitement, “can I trust you
+to keep a big secret?”
+</p>
+
+<p>
+Craig looked at him reproachfully, but said nothing.
+</p>
+
+<p>
+“I beg your pardon—a thousand times,” hastened Burke. “I was so excited, I
+wasn’t thinking—”
+</p>
+
+<p>
+“Once is enough, Burke,” laughed Kennedy, his good nature restored at Burke’s
+crestfallen appearance.
+</p>
+
+<p>
+“Well, you see,” went on the Secret Service man, “this thing is so very
+important that—well, I forgot.”
+</p>
+
+<p>
+He sat down and hitched his chair close to us, as he went on in a lowered,
+almost awestruck tone.
+</p>
+
+<p>
+“Kennedy,” he whispered, “I’m on the trail, I think, of something growing out
+of these terrible conditions in Europe that will tax the best in the Secret
+Service. Think of it, man. There’s an organization, right here in this city, a
+sort of assassin’s club, as it were, aimed at all the powerful men the world
+over. Why, the most refined and intellectual reformers have joined with the
+most red-handed anarchists and—”
+</p>
+
+<p>
+“Sh! not so loud,” cautioned Craig. “I think I have one of them in the next
+room. Have they done anything yet to the Baron?”
+</p>
+
+<p>
+It was Burke’s turn now to look from one to the other of us in unfeigned
+surprise that we should already know something of his secret.
+</p>
+
+<p>
+“The Baron?” he repeated, lowering his voice. “What Baron?”
+</p>
+
+<p>
+It was evident that Burke knew nothing, at least of this new plot which Miss
+Lowe had indicated. Kennedy beckoned him over to the window furthest from the
+door to his own room.
+</p>
+
+<p>
+“What have you discovered?” he asked, forestalling Burke in the questioning.
+“What has happened?”
+</p>
+
+<p>
+“You haven’t heard, then?” replied Burke.
+</p>
+
+<p>
+Kennedy nodded negatively.
+</p>
+
+<p>
+“Fortescue, the American inventor of fortescite, the new explosive, died very
+strangely this morning.”
+</p>
+
+<p>
+“Yes,” encouraged Kennedy, as Burke came to a full stop to observe the effect
+of the information.
+</p>
+
+<p>
+“Most incomprehensible, too,” he pursued. “No cause, apparently. But it might
+have been overlooked, perhaps, except for one thing. It wasn’t known generally,
+but Fortescue had just perfected a successful electro-magnetic gun—powderless,
+smokeless, flashless, noiseless and of tremendous power. To-morrow he was to
+have signed the contract to sell it to England. This morning he is found dead
+and the final plans of the gun are gone!”
+</p>
+
+<p>
+Kennedy and Burke were standing mutely looking at each other.
+</p>
+
+<p>
+“Who is in the next room?” whispered Burke hoarsely, recollecting Kennedy’s
+caution of silence.
+</p>
+
+<p>
+Kennedy did not reply immediately. He was evidently much excited by Burke’s
+news of the wonderful electro-magnetic gun.
+</p>
+
+<p>
+“Burke,” he exclaimed suddenly, “let’s join forces. I think we are both on the
+trail of a world-wide conspiracy—a sort of murder syndicate to wipe out war!”
+</p>
+
+<p>
+Burke’s only reply was a low whistle that involuntarily escaped him as he
+reached over and grasped Craig’s hand, which to him represented the sealing of
+the compact.
+</p>
+
+<p>
+As for me, I could not restrain a mental shudder at the power that their first
+murder had evidently placed in the hands of the anarchists, if they indeed had
+the electro-magnetic gun which inventors had been seeking for generations. What
+might they not do with it—perhaps even use it themselves and turn the latest
+invention against society itself!
+</p>
+
+<p>
+Hastily Craig gave a whispered account of our strange visit from Miss Lowe,
+while Burke listened, open-mouthed.
+</p>
+
+<p>
+He had scarcely finished when he reached for the telephone and asked for long
+distance.
+</p>
+
+<p>
+“Is this the German embassy in Washington?” asked Craig a few moments later
+when he got his number. “This is Craig Kennedy, in New York. The United States
+Secret Service will vouch for me—mention to them Mr. Burke of their New York
+office who is here with me now. I understand that Baron Kreiger is leaving for
+New York to meet some bankers this afternoon. He must not do so. He is in the
+gravest danger if he—What? He left last night at midnight and is already here?”
+</p>
+
+<p>
+Kennedy turned to us blankly.
+</p>
+
+<p>
+The door to his room opened suddenly.
+</p>
+
+<p>
+There stood Miss Lowe, gazing wild-eyed at us. Evidently her supernervous
+condition had heightened the keenness of her senses. She had heard what we were
+saying. I tried to read her face. It was not fear that I saw there. It was
+rage; it was jealousy.
+</p>
+
+<p>
+“The traitress—it is Marie!” she shrieked.
+</p>
+
+<p>
+For a moment, obtusely, I did not understand.
+</p>
+
+<p>
+“She has made a secret appointment with him,” she cried.
+</p>
+
+<p>
+At last I saw the truth. Paula Lowe had fallen in love with the man she had
+sworn to kill!

+<h2><a name="chap02"></a>CHAPTER II<br/>
+THE ELECTRO-MAGNETIC GUN</h2>
+
+<p>
+“What shall we do?” demanded Burke, instantly taking in the dangerous situation
+that the Baron’s sudden change of plans had opened up.
+</p>
+
+<p>
+“Call O’Connor,” I suggested, thinking of the police bureau of missing persons,
+and reaching for the telephone.
+</p>
+
+<p>
+“No, no!” almost shouted Craig, seizing my arm. “The police will inevitably
+spoil it all. No, we must play a lone hand in this if we are to work it out.
+How was Fortescue discovered, Burke?”
+</p>
+
+<p>
+“Sitting in a chair in his laboratory. He must have been there all night. There
+wasn’t a mark on him, not a sign of violence, yet his face was terribly drawn
+as though he were gasping for breath or his heart had suddenly failed him. So
+far, I believe, the coroner has no clue and isn’t advertising the case.”
+</p>
+
+<p>
+“Take me there, then,” decided Craig quickly. “Walter, I must trust Miss Lowe
+to you on the journey. We must all go. That must be our starting point, if we
+are to run this thing down.”
+</p>
+
+<p>
+I caught his significant look to me and interpreted it to mean that he wanted
+me to watch Miss Lowe especially. I gathered that taking her was in the nature
+of a third degree and as a result he expected to derive some information from
+her. Her face was pale and drawn as we four piled into a taxicab for a quick
+run downtown to the laboratory of Fortescue from which Burke had come directly
+to us with his story.
+</p>
+
+<p>
+“What do you know of these anarchists?” asked Kennedy of Burke as we sped
+along. “Why do you suspect them?”
+</p>
+
+<p>
+It was evident that he was discussing the case so that Paula could overhear,
+for a purpose.
+</p>
+
+<p>
+“Why, we received a tip from abroad—I won’t say where,” replied Burke
+guardedly, taking his cue. “They call themselves the ‘Group,’ I believe, which
+is a common enough term among anarchists. It seems they are composed of
+terrorists of all nations.”
+</p>
+
+<p>
+“The leader?” inquired Kennedy, leading him on.
+</p>
+
+<p>
+“There is one, I believe, a little florid, stout German. I think he is a
+paranoiac who believes there has fallen on himself a divine mission to end all
+warfare. Quite likely he is one of those who have fled to America to avoid
+military service. Perhaps, why certainly, you must know him—Annenberg, an
+instructor in economics now at the University?”
+</p>
+
+<p>
+Craig nodded and raised his eyebrows in mild surprise. We had indeed heard of
+Annenberg and some of his radical theories which had sometimes quite alarmed
+the conservative faculty. I felt that this was getting pretty close home to us
+now.
+</p>
+
+<p>
+“How about Mrs. Annenberg?” Craig asked, recalling the clever young wife of the
+middle-aged professor.
+</p>
+
+<p>
+At the mere mention of the name, I felt a sort of start in Miss Lowe, who was
+seated next to me in the taxicab. She had quickly recovered herself, but not
+before I saw that Kennedy’s plan of breaking down the last barrier of her
+reserve was working.
+</p>
+
+<p>
+“She is one of them, too,” Burke nodded. “I have had my men out shadowing them
+and their friends. They tell me that the Annenbergs hold salons—I suppose you
+would call them that—attended by numbers of men and women of high social and
+intellectual position who dabble in radicalism and all sorts of things.”
+</p>
+
+<p>
+“Who are the other leaders?” asked Craig. “Have you any idea?”
+</p>
+
+<p>
+“Some idea,” returned Burke. “There seems to be a Frenchman, a tall, wiry man
+of forty-five or fifty with a black mustache which once had a military twist.
+There are a couple of Englishmen. Then there are five or six Americans who seem
+to be active. One, I believe, is a young woman.”
+</p>
+
+<p>
+Kennedy checked him with a covert glance, but did not betray by a movement of a
+muscle to Miss Lowe that either Burke or himself suspected her of being the
+young woman in question.
+</p>
+
+<p>
+“There are three Russians,” continued Burke, “all of whom have escaped from
+Siberia. Then there is at least one Austrian, a Spaniard from the Ferrer
+school, and Tomasso and Enrico, two Italians, rather heavily built, swarthy,
+bearded. They look the part. Of course there are others. But these in the main,
+I think, compose what might be called ‘the inner circle’ of the ‘Group.’”
+</p>
+
+<p>
+It was indeed an alarming, terrifying revelation, as we began to realize that
+Miss Lowe had undoubtedly been telling the truth. Not alone was there this
+American group, evidently, but all over Europe the lines of the conspiracy had
+apparently spread. It was not a casual gathering of ordinary malcontents. It
+went deeper than that. It included many who in their disgust at war secretly
+were not unwilling to wink at violence to end the curse. I could not but
+reflect on the dangerous ground on which most of them were treading, shaking
+the basis of all civilization in order to cut out one modern excrescence.
+</p>
+
+<p>
+The big fact to us, just at present, was that this group had made America its
+headquarters, that plans had been studiously matured and even reduced to
+writing, if Paula were to be believed. Everything had been carefully staged for
+a great simultaneous blow or series of blows that would rouse the whole world.
+</p>
+
+<p>
+As I watched I could not escape observing that Miss Lowe followed Burke
+furtively now, as though he had some uncanny power.
+</p>
+
+<p>
+Fortescue’s laboratory was in an old building on a side street several blocks
+from the main thoroughfares of Manhattan. He had evidently chosen it, partly
+because of its very inaccessibility in order to secure the quiet necessary for
+his work.
+</p>
+
+<p>
+“If he had any visitors last night,” commented Kennedy when our cab at last
+pulled up before the place, “they might have come and gone unnoticed.”
+</p>
+
+<p>
+We entered. Nothing had been disturbed in the laboratory by the coroner and
+Kennedy was able to gain a complete idea of the case rapidly, almost as well as
+if we had been called in immediately.
+</p>
+
+<p>
+Fortescue’s body, it seemed, had been discovered sprawled out in a big
+armchair, as Burke had said, by one of his assistants only a few hours before
+when he had come to the laboratory in the morning to open it. Evidently he had
+been there undisturbed all night, keeping a gruesome vigil over his looted
+treasure house.
+</p>
+
+<p>
+As we gleaned the meager facts, it became more evident that whoever had
+perpetrated the crime must have had the diabolical cunning to do it in some
+ordinary way that aroused no suspicion on the part of the victim, for there was
+no sign of any violence anywhere.
+</p>
+
+<p>
+As we entered the laboratory, I noted an involuntary shudder on the part of
+Paula Lowe, but, as far as I knew, it was no more than might have been felt by
+anyone under the circumstances.
+</p>
+
+<p>
+Fortescue’s body had been removed from the chair in which it had been found and
+lay on a couch at the other end of the room, covered merely by a sheet.
+Otherwise, everything, even the armchair, was undisturbed.
+</p>
+
+<p>
+Kennedy pulled back a corner of the sheet, disclosing the face, contorted and
+of a peculiar, purplish hue from the congested blood vessels. He bent over and
+I did so, too. There was an unmistakable odor of tobacco on him. A moment
+Kennedy studied the face before us, then slowly replaced the sheet.
+</p>
+
+<p>
+Miss Lowe had paused just inside the door and seemed resolutely bound not to
+look at anything. Kennedy meanwhile had begun a most minute search of the table
+and floor of the laboratory near the spot where the armchair had been sitting.
+</p>
+
+<p>
+In my effort to glean what I could from her actions and expressions I did not
+notice that Craig had dropped to his knees and was peering into the shadow
+under the laboratory table. When at last he rose and straightened himself up,
+however, I saw that he was holding in the palm of his hand a half-smoked,
+gold-tipped cigarette, which had evidently fallen on the floor beneath the
+table where it had burned itself out, leaving a blackened mark on the wood.
+</p>
+
+<p>
+An instant afterward he picked out from the pile of articles found in
+Fortescue’s pockets and lying on another table a silver cigarette case. He
+snapped it open. Fortescue’s cigarettes, of which there were perhaps a half
+dozen in the case, were cork-tipped.
+</p>
+
+<p>
+Some one had evidently visited the inventor the night before, had apparently
+offered him a cigarette, for there were any number of the cork-tipped stubs
+lying about. Who was it? I caught Paula looking with fascinated gaze at the
+gold-tipped stub, as Kennedy carefully folded it up in a piece of paper and
+deposited it in his pocket. Did she know something about the case, I wondered?
+</p>
+
+<p>
+Without a word, Kennedy seemed to take in the scant furniture of the laboratory
+at a glance and a quick step or two brought him before a steel filing cabinet.
+One drawer, which had not been closed as tightly as the rest, projected a bit.
+On its face was a little typewritten card bearing the inscription: “E-M GUN.”
+</p>
+
+<p>
+He pulled the drawer open and glanced over the data in it.
+</p>
+
+<p>
+“Just what is an electro-magnetic gun?” I asked, interpreting the initials on
+the drawer.
+</p>
+
+<p>
+“Well,” he explained as he turned over the notes and sketches, “the primary
+principle involved in the construction of such a gun consists in impelling the
+projectile by the magnetic action of a solenoid, the sectional coils or helices
+of which are supplied with current through devices actuated by the projectile
+itself. In other words, the sections of helices of the solenoid produce an
+accelerated motion of the projectile by acting successively on it, after a
+principle involved in the construction of electro-magnetic rock drills and
+dispatch tubes.
+</p>
+
+<p>
+“All projectiles used in this gun of Fortescue’s evidently must have magnetic
+properties and projectiles of iron or containing large portions of iron are
+necessary. You see, many coils are wound around the barrel of the gun. As the
+projectile starts it does so under the attraction of those coils ahead which
+the current makes temporary magnets. It automatically cuts off the current from
+those coils that it passes, allowing those further on only to attract it, and
+preventing those behind from pulling it back.”
+</p>
+
+<p>
+He paused to study the scraps of plans. “Fortescue had evidently also worked
+out a way of changing the poles of the coils as the projectile passed, causing
+them then to repel the projectile, which must have added to its velocity. He
+seems to have overcome the practical difficulty that in order to obtain service
+velocities with service projectiles an enormous number of windings and a
+tremendously long barrel are necessary as well as an abnormally heavy current
+beyond the safe carrying capacity of the solenoid which would raise the
+temperature to a point that would destroy the coils.”
+</p>
+
+<p>
+He continued turning over the prints and notes in the drawer. When he finished,
+he looked up at us with an expression that indicated that he had merely
+satisfied himself of something he had already suspected.
+</p>
+
+<p>
+“You were right, Burke,” he said. “The final plans are gone.”
+</p>
+
+<p>
+Burke, who, in the meantime, had been telephoning about the city in a vain
+effort to locate Baron Kreiger, both at such banking offices in Wall Street as
+he might be likely to visit and at some of the hotels most frequented by
+foreigners, merely nodded. He was evidently at a loss completely how to
+proceed.
+</p>
+
+<p>
+In fact, there seemed to be innumerable problems—to warn Baron Kreiger, to get
+the list of the assassinations, to guard Miss Lowe against falling into the
+hands of her anarchist friends again, to find the murderer of Fortescue, to
+prevent the use of the electro-magnetic gun, and, if possible, to seize the
+anarchists before they had a chance to carry further their plans.
+</p>
+
+<p>
+“There is nothing more that we can do here,” remarked Craig briskly, betraying
+no sign of hesitation. “I think the best thing we can do is to go to my own
+laboratory. There at least there is something I must investigate sooner or
+later.”
+</p>
+
+<p>
+No one offering either a suggestion or an objection, we four again entered our
+cab. It was quite noticeable now that the visit had shaken Paula Lowe, but
+Kennedy still studiously refrained from questioning her, trusting that what she
+had seen and heard, especially Burke’s report as to Baron Kreiger, would have
+its effect.
+</p>
+
+<p>
+Like everyone visiting Craig’s laboratory for the first time, Miss Lowe seemed
+to feel the spell of the innumerable strange and uncanny instruments which he
+had gathered about him in his scientific warfare against crime. I could see
+that she was becoming more and more nervous, perhaps fearing even that in some
+incomprehensible way he might read her own thoughts. Yet one thing I did not
+detect. She showed no disposition to turn back on the course on which she had
+entered by coming to us in the first place.
+</p>
+
+<p>
+Kennedy was quickly and deftly testing the stub of the little thin, gold-tipped
+cigarette.
+</p>
+
+<p>
+“Excessive smoking,” he remarked casually, “causes neuroses of the heart and
+tobacco has a specific affinity for the coronary arteries as well as a
+tremendous effect on the vagus nerve. But I don’t think this was any ordinary
+smoke.”
+</p>
+
+<p>
+He had finished his tests and a quiet smile of satisfaction flitted momentarily
+over his face. We had been watching him anxiously, wondering what he had found.
+</p>
+
+<p>
+As he looked up he remarked to us, with his eyes fixed on Miss Lowe, “That was
+a ladies’ cigarette. Did you notice the size? There has been a woman in this
+case—presumably.”
+</p>
+
+<p>
+The girl, suddenly transformed by the rapid-fire succession of discoveries,
+stood before us like a specter.
+</p>
+
+<p>
+“The ‘Group,’ as anarchists call it,” pursued Craig, “is the loosest sort of
+organization conceivable, I believe, with no set membership, no officers, no
+laws—just a place of meeting with no fixity, where the comrades get together.
+Could you get us into the inner circle, Miss Lowe?”
+</p>
+
+<p>
+Her only answer was a little suppressed scream. Kennedy had asked the question
+merely for its effect, for it was only too evident that there was no time, even
+if she could have managed it, for us to play the “stool pigeon.”
+</p>
+
+<p>
+Kennedy, who had been clearing up the materials he had used in the analysis of
+the cigarette, wheeled about suddenly. “Where is the headquarters of the inner
+circle?” he shot out.
+</p>
+
+<p>
+Miss Lowe hesitated. That had evidently been one of the things she had
+determined not to divulge.
+</p>
+
+<p>
+“Tell me,” insisted Kennedy. “You must!”
+</p>
+
+<p>
+If it had been Burke’s bulldozing she would never have yielded. But as she
+looked into Kennedy’s eyes she read there that he had long since fathomed the
+secret of her wildly beating heart, that if she would accomplish the purpose of
+saving the Baron she must stop at nothing.
+</p>
+
+<p>
+“At—Maplehurst,” she answered in a low tone, dropping her eyes from his
+penetrating gaze, “Professor Annenberg’s home—out on Long Island.”
+</p>
+
+<p>
+“We must act swiftly if we are to succeed,” considered Kennedy, his tone
+betraying rather sympathy with than triumph over the wretched girl who had at
+last cast everything in the balance to outweigh the terrible situation into
+which she had been drawn. “To send Miss Lowe for that fatal list of
+assassinations is to send her either back into the power of this murderous
+group and let them know that she has told us, or perhaps to involve her again
+in the completion of their plans.”
+</p>
+
+<p>
+She sank back into a chair in complete nervous and physical collapse, covering
+her face with her hands at the realization that in her new-found passion to
+save the Baron she had bared her sensitive soul for the dissection of three men
+whom she had never seen before.
+</p>
+
+<p>
+“We must have that list,” pursued Kennedy decisively. “We must visit
+Annenberg’s headquarters.”
+</p>
+
+<p>
+“And I?” she asked, trembling now with genuine fear at the thought that he
+might ask her to accompany us as he had on our visit to Fortescue’s laboratory
+that morning.
+</p>
+
+<p>
+“Miss Lowe,” said Kennedy, bending over her, “you have gone too far now ever to
+turn back. You are not equal to the trip. Would you like to remain here? No one
+will suspect. Here at least you will be safe until we return.”
+</p>
+
+<p>
+Her answer was a mute expression of thanks and confidence.

+<h2><a name="chap03"></a>CHAPTER III<br/>
+THE MURDER SYNDICATE</h2>
+
+<p>
+Quickly now Craig completed his arrangements for the visit to the headquarters
+of the real anarchist leader. Burke telephoned for a high-powered car, while
+Miss Lowe told frankly of the habits of Annenberg and the chances of finding
+his place unguarded, which were good in the daytime. Kennedy’s only equipment
+for the excursion consisted in a small package which he took from a cabinet at
+the end of the room, and, with a parting reassurance to Paula Lowe, we were
+soon speeding over the bridge to the borough across the river.
+</p>
+
+<p>
+We realized that it might prove a desperate undertaking, but the crisis was
+such that it called for any risk.
+</p>
+
+<p>
+Our quest took us to a rather dilapidated old house on the outskirts of the
+little Long Island town. The house stood alone, not far from the tracks of a
+trolley that ran at infrequent intervals. Even a hasty reconnoitering showed
+that to stop our motor at even a reasonable distance from it was in itself to
+arouse suspicion.
+</p>
+
+<p>
+Although the house seemed deserted, Craig took no chances, but directed the car
+to turn at the next crossroad and then run back along a road back of and
+parallel to that on which Annenberg’s was situated. It was perhaps a quarter of
+a mile away, across an open field, that we stopped and ran the car up along the
+side of the road in some bushes. Annenberg’s was plainly visible and it was not
+at all likely that anyone there would suspect trouble from that quarter.
+</p>
+
+<p>
+A hasty conference with Burke followed, in which Kennedy unwrapped his small
+package, leaving part of its contents with him, and adding careful
+instructions.
+</p>
+
+<p>
+Then Kennedy and I retraced our steps down the road, across by the crossroad,
+and at last back to the mysterious house.
+</p>
+
+<p>
+To all appearance there had been no need of such excessive caution. Not a sound
+or motion greeted us as we entered the gate and made our way around to the rear
+of the house. The very isolation of the house was now our protection, for we
+had no inquisitive neighbors to watch us for the instant when Kennedy, with the
+dexterity of a yeggman, inserted his knife between the sashes of the kitchen
+window and turned the catch which admitted us.
+</p>
+
+<p>
+We made our way on cautious tiptoe through a dining room to a living room, and,
+finding nothing, proceeded upstairs. There was not a soul, apparently, in the
+house, nor in fact anything to indicate that it was different from most small
+suburban homes, until at last we mounted to the attic.
+</p>
+
+<p>
+It was finished off in one large room across the back of the house and two in
+front. As we opened the door to the larger room, we could only gaze about in
+surprise. This was the rendezvous, the arsenal, literary, explosive and
+toxicological of the “Group.” Ranged on a table were all the materials for
+bomb-making, while in a cabinet I fancied there were poisons enough to decimate
+a city.
+</p>
+
+<p>
+On the walls were pictures, mostly newspaper prints, of the assassins of
+McKinley, of King Humbert, of the King of Greece, of King Carlos and others,
+interspersed with portraits of anarchist and anti-militarist leaders of all
+lands.
+</p>
+
+<p>
+Kennedy sniffed. Over all I, too, could catch the faint odor of stale tobacco.
+No time was to be lost, however, and while Craig set to work rapidly going
+through the contents of a desk in the corner, I glanced over the contents of a
+drawer of a heavy mission table.
+</p>
+
+<p>
+“Here’s some of Annenberg’s literature,” I remarked, coming across a small pile
+of manuscript, entitled “The Human Slaughter House.”
+</p>
+
+<p>
+“Read it,” panted Kennedy, seeing that I had about completed my part of the
+job. “It may give a clue.”
+</p>
+
+<p>
+Hastily I scanned the mad, frantic indictment of war, while Craig continued in
+his search:

+“I see wild beasts all around me, distorted unnaturally, in a life and death
+struggle, with bloodshot eyes, with foaming, gnashing mouths. They attack and
+kill one another and try to mangle each other. I leap to my feet. I race out
+into the night and tread on quaking flesh, step on hard heads, and stumble over
+weapons and helmets. Something is clutching at my feet like hands, so that I
+race away like a hunted deer with the hounds at his heels—and ever over more
+bodies—breathless… out of one field into another. Horror is crooning over my
+head. Horror is crooning beneath my feet. And nothing but dying, mangled flesh!
+</p>
+
+<p>
+“Of a sudden I see nothing but blood before me. The heavens have opened and the
+red blood pours in through the windows. Blood wells up on an altar. The walls
+run blood from the ceiling to the floor and… a giant of blood stands before me.
+His beard and his hair drip blood. He seats himself on the altar and laughs
+from thick lips. The black executioner raises his sword and whirls it above my
+head. Another moment and my head will roll down on the floor. Another moment
+and the red jet will spurt from my neck.
+</p>
+
+<p>
+“Murderers! Murderers! None other than murderers!”
+</p>
+
+<p class="p2">
+I paused in the reading. “There’s nothing here,” I remarked, glancing over the
+curious document for a clue, but finding none.
+</p>
+
+<p>
+“Well,” remarked Craig contemplatively, “one can at least easily understand how
+sensitive and imaginative people who have fallen under the influence of one who
+writes in that way can feel justified in killing those responsible for bringing
+such horrors on the human race. Hello—what’s this?”
+</p>
+
+<p>
+He had discovered a false back of one of the drawers in the desk and had
+jimmied it open. On the top of innumerable papers lay a large linen envelope.
+On its face it bore in typewriting, just like the card on the drawer at
+Fortescue’s, “E-M GUN.”
+</p>
+
+<p>
+“It is the original envelope that contained the final plans of the
+electro-magnetic gun,” he explained, opening it.
+</p>
+
+<p>
+The envelope was empty. We looked at each other a moment in silence. What had
+been done with the plans?
+</p>
+
+<p>
+Suddenly a bell rang, startling me beyond measure. It was, however, only the
+telephone, of which an extension reached up into the attic-arsenal. Some one,
+who did not know that we were there, was evidently calling up.
+</p>
+
+<p>
+Kennedy quickly unhooked the receiver with a hasty motion to me to be silent.
+</p>
+
+<p>
+“Hello,” I heard him answer. “Yes, this is it.”
+</p>
+
+<p>
+He had disguised his voice. I waited anxiously and watched his face to gather
+what response he received.
+</p>
+
+<p>
+“The deuce!” he exclaimed, with his hand over the transmitter so that his voice
+would not be heard at the other end of the line.
+</p>
+
+<p>
+“What’s the matter?” I asked eagerly.
+</p>
+
+<p>
+“It was Mrs. Annenberg—I am sure. But she was too keen for me. She caught on.
+There must be some password or form of expression that they use, which we don’t
+know, for she hung up the receiver almost as soon as she heard me.”
+</p>
+
+<p>
+Kennedy waited a minute or so. Then he whistled into the transmitter. It was
+done apparently to see whether there was anyone listening. But there was no
+answer.
+</p>
+
+<p>
+“Operator, operator!” he called insistently, moving the hook up and down. “Yes,
+operator. Can you tell me what number that was which just called?”
+</p>
+
+<p>
+He waited impatiently.
+</p>
+
+<p>
+“Bleecker—7l80,” he repeated after the girl. “Thank you. Information, please.”
+</p>
+
+<p>
+Again we waited, as Craig tried to trace the call up.
+</p>
+
+<p>
+“What is the street address of Bleecker, 7180?” he asked. “Five hundred and one
+East Fifth—a tenement. Thank you.”
+</p>
+
+<p>
+“A tenement?” I repeated blankly.
+</p>
+
+<p>
+“Yes,” he cried, now for the first time excited. “Don’t you begin to see the
+scheme? I’ll wager that Baron Kreiger has been lured to New York to purchase
+the electro-magnetic gun which they have stolen from Fortescue and the British.
+That is the bait that is held out to him by the woman. Call up Miss Lowe at the
+laboratory and see if she knows the place.”
+</p>
+
+<p>
+I gave central the number, while he fell to at the little secret drawer of the
+desk again. The grinding of the wheels of a passing trolley interfered somewhat
+with giving the number and I had to wait a moment.
+</p>
+
+<p>
+“Ah—Walter—here’s the list!” almost shouted Kennedy, as he broke open a
+black-japanned dispatch box in the desk.
+</p>
+
+<p>
+I bent over it, as far as the slack of the telephone wire of the receiver at my
+ear would permit. Annenberg had worked with amazing care and neatness on the
+list, even going so far as to draw at the top, in black, a death’s head. The
+rest of it was elaborately prepared in flaming red ink.
+</p>
+
+<p>
+Craig gasped to observe the list of world-famous men marked for destruction in
+London, Paris, Berlin, Rome, Vienna, St. Petersburg, and even in New York and
+Washington.
+</p>
+
+<p>
+“What is the date set?” I asked, still with my ear glued to the receiver.
+</p>
+
+<p>
+“To-night and to-morrow,” he replied, stuffing the fateful sheet into his
+pocket.
+</p>
+
+<p>
+Rummaging about in the drawer of the table, I had come to a package of
+gold-tipped cigarettes which had interested me and I had left them out. Kennedy
+was now looking at them curiously.
+</p>
+
+<p>
+“What is to be the method, do you suppose?” I asked.
+</p>
+
+<p>
+“By a poison that is among the most powerful, approaching even cyanogen,” he
+replied confidently, tapping the cigarettes. “Do you smell the odor in this
+room? What is it like?”
+</p>
+
+<p>
+“Stale tobacco,” I replied.
+</p>
+
+<p>
+“Exactly—nicotine. Two or three drops on the mouth-end of a cigar or cigarette.
+The intended victim thinks it is only natural. But it is the purest form of the
+deadly alkaloid—fatal in a few minutes, too.”
+</p>
+
+<p>
+He examined the thin little cigarettes more carefully. “Nicotine,” he went on,
+“was about the first alkaloid that was recovered from the body by chemical
+analysis in a homicide case. That is the penetrating, persistent odor you
+smelled at Fortescue’s and also here. It’s a very good poison—if you are not
+particular about being discovered. A pound of ordinary smoking tobacco contains
+from a half to an ounce of it. It is almost entirely consumed by combustion;
+otherwise a pipeful would be fatal. Of course they may have thought that
+investigators would believe that their victims were inveterate smokers. But
+even the worst tobacco fiend wouldn’t show traces of the weed to such an
+extent.”
+</p>
+
+<p>
+Miss Lowe answered at last and Kennedy took the telephone.
+</p>
+
+<p>
+“What is at five hundred and one East Fifth?” he asked.
+</p>
+
+<p>
+“A headquarters of the Group in the city,” she answered. “Why?”
+</p>
+
+<p>
+“Well, I believe that the plans of that gun are there and that the Baron—”
+</p>
+
+<p>
+“You damned spies!” came a voice from behind us.
+</p>
+
+<p>
+Kennedy dropped the receiver, turning quickly, his automatic gleaming in his
+hand.
+</p>
+
+<p>
+There was just a glimpse of a man with glittering bright blue eyes that had an
+almost fiendish, baleful glare. An instant later the door which had so
+unexpectedly opened banged shut, we heard a key turn in the lock—and the man
+dropped to the floor before even Kennedy’s automatic could test its ability to
+penetrate wood on a chance at hitting something the other side of it.
+</p>
+
+<p>
+We were prisoners!
+</p>
+
+<p>
+My mind worked automatically. At this very moment, perhaps, Baron Kreiger might
+be negotiating for the electro-magnetic gun. We had found out where he was, in
+all probability, but we were powerless to help him. I thought of Miss Lowe, and
+picked up the receiver which Kennedy had dropped.
+</p>
+
+<p>
+She did not answer. The wire had been cut. We were isolated!
+</p>
+
+<p>
+Kennedy had jumped to the window. I followed to restrain him, fearing that he
+had some mad scheme for climbing out. Instead, quickly he placed a peculiar
+arrangement, from the little package he had brought, holding it to his eye as
+if sighting it, his right hand grasping a handle as one holds a stereoscope. A
+moment later, as I examined it more closely, I saw that instead of looking at
+anything he had before him a small parabolic mirror turned away from him.
+</p>
+
+<p>
+His finger pressed alternately on a button on the handle and I could see that
+there flashed in the little mirror a minute incandescent lamp which seemed to
+have a special filament arrangement.
+</p>
+
+<p>
+The glaring sun was streaming in at the window and I wondered what could
+possibly be accomplished by the little light in competition with the sun
+itself.
+</p>
+
+<p>
+“Signaling by electric light in the daytime may sound to you ridiculous,”
+explained Craig, still industriously flashing the light, “but this arrangement
+with Professor Donath’s signal mirror makes it possible, all right.
+</p>
+
+<p>
+“I hadn’t expected this, but I thought I might want to communicate with Burke
+quickly. You see, I sight the lamp and then press the button which causes the
+light in the mirror to flash. It seems a paradox that a light like this can be
+seen from a distance of even five miles and yet be invisible to one for whom it
+was not intended, but it is so. I use the ordinary Morse code—two seconds for a
+dot, six for a dash with a four-second interval.”
+</p>
+
+<p>
+“What message did you send?” I asked.
+</p>
+
+<p>
+“I told him that Baron Kreiger was at five hundred and one East Fifth,
+probably; to get the secret service office in New York by wire and have them
+raid the place, then to come and rescue us. That was Annenberg. He must have
+come up by that trolley we heard passing just before.”
+</p>
+
+<p>
+The minutes seemed ages as we waited for Burke to start the machinery of the
+raid and then come for us.
+</p>
+
+<p>
+“No—you can’t have a cigarette—and if I had a pair of bracelets with me, I’d
+search you myself,” we heard a welcome voice growl outside the door a few
+minutes later. “Look in that other pocket, Tom.”
+</p>
+
+<p>
+The lock grated back and there stood Burke holding in a grip of steel the
+undersized Annenberg, while the chauffeur who had driven our car swung open the
+door.
+</p>
+
+<p>
+“I’d have been up sooner,” apologized Burke, giving the anarchist an extra
+twist just to let him know that he was at last in the hands of the law, “only I
+figured that this fellow couldn’t have got far away in this God-forsaken
+Ducktown and I might as well pick him up while I had a chance. That’s a great
+little instrument of yours, Kennedy. I got you, fine.”
+</p>
+
+<p>
+Annenberg, seeing we were now four to one, concluded that discretion was the
+better part of valor and ceased to struggle, though now and then I could see he
+glanced at Kennedy out of the corner of his eye. To every question he
+maintained a stolid silence.
+</p>
+
+<p>
+A few minutes later, with the arch anarchist safely pinioned between us, we
+were speeding back toward New York, laying plans for Burke to dispatch warnings
+abroad to those whose names appeared on the fatal list, and at the same time to
+round up as many of the conspirators as possible in America.
+</p>
+
+<p>
+As for Kennedy, his main interest now lay in Baron Kreiger and Paula. While she
+had been driven frantic by the outcome of the terrible pact into which she had
+been drawn, some one, undoubtedly, had been trying to sell Baron Kreiger the
+gun that had been stolen from the American inventor. Once they had his money
+and he had received the plans of the gun, a fatal cigarette would be smoked.
+Could we prevent it?
+</p>
+
+<p>
+On we tore back to the city, across the bridge and down through the canyons of
+East Side streets.
+</p>
+
+<p>
+At last we pulled up before the tenement at five hundred and one. As we did so,
+one of Burke’s men jumped out of the doorway.
+</p>
+
+<p>
+“Are we in time?” shouted Burke.
+</p>
+
+<p>
+“It’s an awful mix-up,” returned the man. “I can’t make anything out of it, so
+I ordered ’em all held here till you came.”
+</p>
+
+<p>
+We pushed past without a word of criticism of his wonderful acumen.
+</p>
+
+<p>
+On the top floor we came upon a young man, bending over the form of a girl who
+had fainted. On the floor of the middle of the room was a mass of charred
+papers which had evidently burned a hole in the carpet before they had been
+stamped out. Near by was an unlighted cigarette, crushed flat on the floor.
+</p>
+
+<p>
+“How is she?” asked Kennedy anxiously of the young man, as he dropped down on
+the other side of the girl.
+</p>
+
+<p>
+It was Paula. She had fainted, but was just now coming out of the borderland of
+unconsciousness.
+</p>
+
+<p>
+“Was I in time? Had he smoked it?” she moaned weakly, as there swam before her
+eyes, evidently, a hazy vision of our faces.
+</p>
+
+<p>
+Kennedy turned to the young man.
+</p>
+
+<p>
+“Baron Kreiger, I presume?” he inquired.
+</p>
+
+<p>
+The young man nodded.
+</p>
+
+<p>
+“Burke of the Secret Service,” introduced Craig, indicating our friend. “My
+name is Kennedy. Tell what happened.”
+</p>
+
+<p>
+“I had just concluded a transaction,” returned Kreiger in good but carefully
+guarded English. “Suddenly the door burst open. She seized these papers and
+dashed a cigarette out of my hands. The next instant she had touched a match to
+them and had fallen in a faint almost in the blaze. Strangest experience I ever
+had in my life. Then all these other fellows came bursting in—said they were
+Secret Service men, too.”
+</p>
+
+<p>
+Kennedy had no time to reply, for a cry from Annenberg directed our attention
+to the next room where on a couch lay a figure all huddled up.
+</p>
+
+<p>
+As we looked we saw it was a woman, her head sweating profusely, and her hands
+cold and clammy. There was a strange twitching of the muscles of the face, the
+pupils of her eyes were widely dilated, her pulse weak and irregular. Evidently
+her circulation had failed so that it responded only feebly to stimulants, for
+her respiration was slow and labored, with loud inspiratory gasps.
+</p>
+
+<p>
+Annenberg had burst with superhuman strength from Burke’s grasp and was
+kneeling by the side of his wife’s deathbed.
+</p>
+
+<p>
+“It—was all Paula’s fault—” gasped the woman. “I—knew I had better—carry it
+through—like the Fortescue visit—alone.”
+</p>
+
+<p>
+I felt a sense of reassurance at the words. At least my suspicions had been
+unfounded. Paula was innocent of the murder of Fortescue.
+</p>
+
+<p>
+“Severe, acute nicotine poisoning,” remarked Kennedy, as he rejoined us a
+moment later. “There is nothing we can do—now.”
+</p>
+
+<p>
+Paula moved at the words, as though they had awakened a new energy in her. With
+a supreme effort she raised herself.
+</p>
+
+<p>
+“Then I—I failed?” she cried, catching sight of Kennedy.
+</p>
+
+<p>
+“No, Miss Lowe,” he answered gently. “You won. The plans of the terrible gun
+are destroyed. The Baron is safe. Mrs. Annenberg has herself smoked one of the
+fatal cigarettes intended for him.”
+</p>
+
+<p>
+Kreiger looked at us, uncomprehending. Kennedy picked up the crushed, unlighted
+cigarette and laid it in the palm of his hand beside another, half smoked,
+which he had found beside Mrs. Annenberg.
+</p>
+
+<p>
+“They are deadly,” he said simply to Kreiger. “A few drops of pure nicotine
+hidden by that pretty gilt tip would have accomplished all that the bitterest
+anarchist could desire.”
+</p>
+
+<p>
+All at once Kreiger seemed to realize what he had escaped so narrowly. He
+turned toward Paula. The revulsion of her feelings at seeing him safe was too
+much for her shattered nerves.
+</p>
+
+<p>
+With a faint little cry, she tottered.
+</p>
+
+<p>
+Before any of us could reach her, he had caught her in his arms and imprinted a
+warm kiss on the insensible lips.
+</p>
+
+<p>
+“Some water—quick!” he cried, still holding her close.

+THE AIR PIRATE</h2>
+
+<p>
+Rounding up the “Group” took several days, and it proved to be a great story
+for the <i>Star</i>. I was pretty fagged when it was all over, but there was a
+great deal of satisfaction in knowing that we had frustrated one of the most
+daring anarchist plots of recent years.
+</p>
+
+<p>
+“Can you arrange to spend the week-end with me at Stuyvesant Verplanck’s at
+Bluffwood?” asked Kennedy over the telephone, the afternoon that I had
+completed my work on the newspaper of undoing what Annenberg and the rest had
+attempted.
+</p>
+
+<p>
+“How long since society took you up?” I asked airily, adding, “Is it a large
+house party you are getting up?”
+</p>
+
+<p>
+“You have heard of the so-called ‘phantom bandit’ of Bluffwood, haven’t you?”
+he returned rather brusquely, as though there was no time now for bantering.
+</p>
+
+<p>
+I confess that in the excitement of the anarchists I had forgotten it, but now
+I recalled that for several days I had been reading little paragraphs about
+robberies on the big estates on the Long Island shore of the Sound. One of the
+local correspondents had called the robber a “phantom bandit,” but I had
+thought it nothing more than an attempt to make good copy out of a rather
+ordinary occurrence.
+</p>
+
+<p>
+“Well,” he hurried on, “that’s the reason why I have been ‘taken up by
+society,’ as you so elegantly phrase it. From the secret hiding-places of the
+boudoirs and safes of fashionable women at Bluffwood, thousands of dollars’
+worth of jewels and other trinkets have mysteriously vanished. Of course you’ll
+come along. Why, it will be just the story to tone up that alleged page of
+society news you hand out in the Sunday <i>Star</i>. There—we’re quits now.
+Seriously, though, Walter, it really seems to be a very baffling case, or
+rather series of cases. The whole colony out there is terrorized. They don’t
+know who the robber is, or how he operates, or who will be the next victim, but
+his skill and success seem almost uncanny. Mr. Verplanck has put one of his
+cars at my disposal and I’m up here at the laboratory gathering some apparatus
+that may be useful. I’ll pick you up anywhere between this and the Bridge—how
+about Columbus Circle in half an hour?”
+</p>
+
+<p>
+“Good,” I agreed, deciding quickly from his tone and manner of assurance that
+it would be a case I could not afford to miss.
+</p>
+
+<p>
+The Stuyvesant Verplancks, I knew, were among the leaders of the rather
+recherché society at Bluffwood, and the pace at which Bluffwood moved and had
+its being was such as to guarantee a good story in one way or another.
+</p>
+
+<p>
+“Why,” remarked Kennedy, as we sped out over the picturesque roads of the north
+shore of Long Island, “this fellow, or fellows, seems to have taken the measure
+of all the wealthy members of the exclusive organizations out there—the
+Westport Yacht Club, the Bluffwood Country Club, the North Shore Hunt, and all
+of them. It’s a positive scandal, the ease with which he seems to come and go
+without detection, striking now here, now there, often at places that it seems
+physically impossible to get at, and yet always with the same diabolical skill
+and success. One night he will take some baubles worth thousands, the next pass
+them by for something apparently of no value at all, a piece of bric-à-brac, a
+bundle of letters, anything.”
+</p>
+
+<p>
+“Seems purposeless, insane, doesn’t it?” I put in.
+</p>
+
+<p>
+“Not when he always takes something—often more valuable than money,” returned
+Craig.
+</p>
+
+<p>
+He leaned back in the car and surveyed the glimpses of bay and countryside as
+we were whisked by the breaks in the trees.
+</p>
+
+<p>
+“Walter,” he remarked meditatively, “have you ever considered the possibilities
+of blackmail if the right sort of evidence were obtained under this new
+‘white-slavery act’? Scandals that some of the fast set may be inclined to wink
+at, that at worst used to end in Reno, become felonies with federal prison
+sentences looming up in the background. Think it over.”
+</p>
+
+<p>
+Stuyvesant Verplanck had telephoned rather hurriedly to Craig earlier in the
+day, retaining his services, but telling only in the briefest way of the extent
+of the depredations, and hinting that more than jewelry might be at stake.
+</p>
+
+<p>
+It was a pleasant ride, but we finished it in silence. Verplanck was, as I
+recalled, a large masterful man, one of those who demanded and liked large
+things—such as the estate of several hundred acres which we at last entered.
+</p>
+
+<p>
+It was on a neck of land with the restless waters of the Sound on one side and
+the calmer waters of the bay on the other. Westport Bay lay in a beautifully
+wooded, hilly country, and the house itself was on an elevation, with a huge
+sweep of terraced lawn before it down to the water’s edge. All around, for
+miles, were other large estates, a veritable colony of wealth.
+</p>
+
+<p>
+As we pulled up under the broad stone porte-cochère, Verplanck, who had been
+expecting us, led the way into his library, a great room, literally crowded
+with curios and objects of art which he had collected on his travels. It was a
+superb mental workshop, overlooking the bay, with a stretch of several miles of
+sheltered water.
+</p>
+
+<p>
+“You will recall,” began Verplanck, wasting no time over preliminaries, but
+plunging directly into the subject, “that the prominent robberies of late have
+been at seacoast resorts, especially on the shores of Long Island Sound,
+within, say, a hundred miles of New York. There has been a great deal of talk
+about dark and muffled automobiles that have conveyed mysterious parties
+swiftly and silently across country.
+</p>
+
+<p>
+“My theory,” he went on self-assertively, “is that the attack has been made
+always along water routes. Under shadow of darkness, it is easy to slip into
+one of the sheltered coves or miniature fiords with which the north coast of
+the Island abounds, land a cut-throat crew primed with exact information of the
+treasure on some of these estates. Once the booty is secured, the criminal
+could put out again into the Sound without leaving a clue.”
+</p>
+
+<p>
+He seemed to be considering his theory. “Perhaps the robberies last summer at
+Narragansett, Newport, and a dozen other New England places were perpetrated by
+the same cracksman. I believe,” he concluded, lowering his voice, “that there
+plies to-day on the wide waters of the Sound a slim, swift motor boat which
+wears the air of a pleasure craft, yet is as black a pirate as ever flew the
+Jolly Roger. She may at this moment be anchored off some exclusive yacht club,
+flying the respectable burgee of the club—who knows?”
+</p>
+
+<p>
+He paused as if his deductions settled the case so far. He would have resumed
+in the same vein, if the door had not opened. A lady in a cobwebby gown entered
+the room. She was of middle age, but had retained her youth with a skill that
+her sisters of less leisure always envy. Evidently she had not expected to find
+anyone, yet nothing seemed to disconcert her.
+</p>
+
+<p>
+“Mrs. Verplanck,” her husband introduced, “Professor Kennedy and his associate,
+Mr. Jameson—those detectives we have heard about. We were discussing the
+robberies.”
+</p>
+
+<p>
+“Oh, yes,” she said, smiling, “my husband has been thinking of forming himself
+into a vigilance committee. The local authorities are all at sea.”
+</p>
+
+<p>
+I thought there was a trace of something veiled in the remark and fancied, not
+only then but later, that there was an air of constraint between the couple.
+</p>
+
+<p>
+“You have not been robbed yourself?” queried Craig tentatively.
+</p>
+
+<p>
+“Indeed we have,” exclaimed Verplanck quickly. “The other night I was awakened
+by the noise of some one down here in this very library. I fired a shot, wild,
+and shouted, but before I could get down here the intruder had fled through a
+window, and half rolling down the terraces. Mrs. Verplanck was awakened by the
+rumpus and both of us heard a peculiar whirring noise.”
+</p>
+
+<p>
+“Like an automobile muffled down,” she put in.
+</p>
+
+<p>
+“No,” he asserted vigorously, “more like a powerful motor boat, one with the
+exhaust under water.”
+</p>
+
+<p>
+“Well,” she shrugged, “at any rate, we saw no one.”
+</p>
+
+<p>
+“Did the intruder get anything?”
+</p>
+
+<p>
+“That’s the lucky part. He had just opened this safe apparently and begun to
+ransack it. This is my private safe. Mrs. Verplanck has another built into her
+own room upstairs where she keeps her jewels.”
+</p>
+
+<p>
+“It is not a very modern safe, is it?” ventured Kennedy. “The fellow ripped off
+the outer casing with what they call a ‘can-opener.’”
+</p>
+
+<p>
+“No. I keep it against fire rather than burglars. But he overlooked a box of
+valuable heirlooms, some silver with the Verplanck arms. I think I must have
+scared him off just in time. He seized a package in the safe, but it was only
+some business correspondence. I don’t relish having lost it, particularly. It
+related to a gentlemen’s agreement a number of us had in the recent cotton
+corner. I suppose the Government would like to have it. But—here’s the point.
+If it is so easy to get in and get away, no one in Bluffwood is safe.”
+</p>
+
+<p>
+“Why, he robbed the Montgomery Carter place the other night,” remarked Mrs.
+Verplanck, “and almost got a lot of old Mrs. Carter’s jewels as well as stuff
+belonging to her son, Montgomery, Junior. That was the first robbery. Mr.
+Carter, that is Junior—Monty, everyone calls him—and his chauffeur almost
+captured the fellow, but he managed to escape in the woods.”
+</p>
+
+<p>
+“In the woods?” repeated Craig.
+</p>
+
+<p>
+Mrs. Verplanck nodded. “But they saved the loot he was about to take.”
+</p>
+
+<p>
+“Oh, no one is safe any more,” reiterated Verplanck. “Carter seems to be the
+only one who has had a real chance at him, and he was able to get away neatly.”
+</p>
+
+<p>
+“But he’s not the only one who got off without a loss,” she put in
+significantly. “The last visit—” Then she paused.
+</p>
+
+<p>
+“Where was the last attempt?” asked Kennedy.
+</p>
+
+<p>
+“At the house of Mrs. Hollingsworth—around the point on this side of the bay.
+You can’t see it from here.”
+</p>
+
+<p>
+“I’d like to go there,” remarked Kennedy.
+</p>
+
+<p>
+“Very well. Car or boat?”
+</p>
+
+<p>
+“Boat, I think.”
+</p>
+
+<p>
+“Suppose we go in my little runabout, the <i>Streamline II</i>? She’s as fast
+as any ordinary automobile.”
+</p>
+
+<p>
+“Very good. Then we can get an idea of the harbor.”
+</p>
+
+<p>
+“I’ll telephone first that we are coming,” said Verplanck.
+</p>
+
+<p>
+“I think I’ll go, too,” considered Mrs. Verplanck, ringing for a heavy wrap.
+</p>
+
+<p>
+“Just as you please,” said Verplanck.
+</p>
+
+<p>
+The <i>Streamline</i> was a three-stepped boat which. Verplanck had built for
+racing, a beautiful craft, managed much like a racing automobile. As she
+started from the dock, the purring drone of her eight cylinders sent her
+feathering over the waves like a skipping stone. She sank back into the water,
+her bow leaping upward, a cloud of spray in her wake, like a waterspout.
+</p>
+
+<p>
+Mrs. Hollingsworth was a wealthy divorcée, living rather quietly with her two
+children, of whom the courts had awarded her the care. She was a striking
+woman, one of those for whom the new styles of dress seem especially to have
+been designed. I gathered, however, that she was not on very good terms with
+the little Westport clique in which the Verplancks moved, or at least not with
+Mrs. Verplanck. The two women seemed to regard each other rather coldly, I
+thought, although Mr. Verplanck, man-like, seemed to scorn any distinctions and
+was more than cordial. I wondered why Mrs. Verplanck had come.
+</p>
+
+<p>
+The Hollingsworth house was a beautiful little place down the bay from the
+Yacht Club, but not as far as Verplanck’s, or the Carter estate, which was
+opposite.
+</p>
+
+<p>
+“Yes,” replied Mrs. Hollingsworth when the reason for our visit had been
+explained, “the attempt was a failure. I happened to be awake, rather late, or
+perhaps you would call it early. I thought I heard a noise as if some one was
+trying to break into the drawing-room through the window. I switched on all the
+lights. I have them arranged so for just that purpose of scaring off intruders.
+Then, as I looked out of my window on the second floor, I fancied I could see a
+dark figure slink into the shadow of the shrubbery at the side of the house.
+Then there was a whirr. It might have been an automobile, although it sounded
+differently from that—more like a motor boat. At any rate, there was no trace
+of a car that we could discover in the morning. The road had been oiled, too,
+and a car would have left marks. And yet some one was here. There were marks on
+the drawing-room window just where I heard the sounds.”
+</p>
+
+<p>
+Who could it be? I asked myself as we left. I knew that the great army of
+chauffeurs was infested with thieves, thugs and gunmen. Then, too, there were
+maids, always useful as scouts for these corsairs who prey on the rich. Yet so
+adroitly had everything been done in these cases that not a clue seemed to have
+been left behind by which to trace the thief.
+</p>
+
+<p>
+We returned to Verplanck’s in the <i>Streamline</i> in record time, dined, and
+then found McNeill, a local detective, waiting to add his quota of information.
+McNeill was of the square-toed, double-chinned, bull-necked variety, just the
+man to take along if there was any fighting. He had, however, very little to
+add to the solution of the mystery, apparently believing in the
+chauffeur-and-maid theory.
+</p>
+
+<p>
+It was too late to do anything more that night, and we sat on the Verplanck
+porch, overlooking the beautiful harbor. It was a black, inky night, with no
+moon, one of those nights when the myriad lights on the boats were mere points
+in the darkness. As we looked out over the water, considering the case which as
+yet we had hardly started on, Kennedy seemed engrossed in the study in black.
+</p>
+
+<p>
+“I thought I saw a moving light for an instant across the bay, above the boats,
+and as though it were in the darkness of the hills on the other side. Is there
+a road over there, above the Carter house?” he asked suddenly.
+</p>
+
+<p>
+“There is a road part of the way on the crest of the hill,” replied Mrs.
+Verplanck. “You can see a car on it, now and then, through the trees, like a
+moving light.”
+</p>
+
+<p>
+“Over there, I mean,” reiterated Kennedy, indicating the light as it flashed
+now faintly, then disappeared, to reappear further along, like a gigantic
+firefly in the night.
+</p>
+
+<p>
+“N-no,” said Verplanck. “I don’t think the road runs down as far as that. It is
+further up the bay.”
+</p>
+
+<p>
+“What is it then?” asked Kennedy, half to himself. “It seems to be traveling
+rapidly. Now it must be about opposite the Carter house. There—it has gone.”
+</p>
+
+<p>
+We continued to watch for several minutes, but it did not reappear. Could it
+have been a light on the mast of a boat moving rapidly up the bay and perhaps
+nearer to us than we suspected? Nothing further happened, however, and we
+retired early, expecting to start with fresh minds on the case in the morning.
+Several watchmen whom Verplanck employed both on the shore and along the
+driveways were left guarding every possible entrance to the estate.
+</p>
+
+<p>
+Yet the next morning as we met in the cheery east breakfast room, Verplanck’s
+gardener came in, hat in hand, with much suppressed excitement.
+</p>
+
+<p>
+In his hand he held an orange which he had found in the shrubbery underneath
+the windows of the house. In it was stuck a long nail and to the nail was
+fastened a tag.
+</p>
+
+<p>
+Kennedy read it quickly.
+</p>
+
+<p class="letter">
+“If this had been a bomb, you and your detectives would never have known what

+THE ULTRA-VIOLET RAY</h2>
+
+<p>
+“Good Gad, man!” exclaimed Verplanck, who had read it over Craig’s shoulder.
+“What do you make of <i>that?</i>”
+</p>
+
+<p>
+Kennedy merely shook his head. Mrs. Verplanck was the calmest of all.
+</p>
+
+<p>
+“The light,” I cried. “You remember the light? Could it have been a signal to
+some one on this side of the bay, a signal light in the woods?”
+</p>
+
+<p>
+“Possibly,” commented Kennedy absently, adding, “Robbery with this fellow seems
+to be an art as carefully strategized as a promoter’s plan or a merchant’s
+trade campaign. I think I’ll run over this morning and see if there is any
+trace of anything on the Carter estate.”
+</p>
+
+<p>
+Just then the telephone rang insistently. It was McNeill, much excited, though
+he had not heard of the orange incident. Verplanck answered the call.
+</p>
+
+<p>
+“Have you heard the news?” asked McNeill. “They report this morning that that
+fellow must have turned up last night at Belle Aire.”
+</p>
+
+<p>
+“Belle Aire? Why, man, that’s fifty miles away and on the other side of the
+island. He was here last night,” and Verplanck related briefly the find of the
+morning. “No boat could get around the island in that time and as for a
+car—those roads are almost impossible at night.”
+</p>
+
+<p>
+“Can’t help it,” returned McNeill doggedly. “The Halstead estate out at Belle
+Aire was robbed last night. It’s spooky all right.”
+</p>
+
+<p>
+“Tell McNeill I want to see him—will meet him in the village directly,” cut in
+Craig before Verplanck had finished.
+</p>
+
+<p>
+We bolted a hasty breakfast and in one of Verplanck’s cars hurried to meet
+McNeill.
+</p>
+
+<p>
+“What do you intend doing?” he asked helplessly, as Kennedy finished his
+recital of the queer doings of the night before.
+</p>
+
+<p>
+“I’m going out now to look around the Carter place. Can you come along?”
+</p>
+
+<p>
+“Surely,” agreed McNeill, climbing into the car. “You know him?”
+</p>
+
+<p>
+“No.”
+</p>
+
+<p>
+“Then I’ll introduce you. Queer chap, Carter. He’s a lawyer, although I don’t
+think he has much practice, except managing his mother’s estate.”
+</p>
+
+<p>
+McNeill settled back in the luxurious car with an exclamation of satisfaction.
+</p>
+
+<p>
+“What do you think of Verplanck?” he asked.
+</p>
+
+<p>
+“He seems to me to be a very public-spirited man,” answered Kennedy discreetly.
+</p>
+
+<p>
+That, however, was not what McNeill meant and he ignored it. And so for the
+next ten minutes we were entertained with a little retail scandal of Westport
+and Bluffwood, including a tale that seemed to have gained currency that
+Verplanck and Mrs. Hollingsworth were too friendly to please Mrs. Verplanck. I
+set the whole thing down to the hostility and jealousy of the towns people who
+misinterpret everything possible in the smart set, although I could not help
+recalling how quickly she had spoken when we had visited the Hollingsworth
+house in the <i>Streamline</i> the day before.
+</p>
+
+<p>
+Montgomery Carter happened to be at home and, at least openly, interposed no
+objection to our going about the grounds.
+</p>
+
+<p>
+“You see,” explained Kennedy, watching the effect of his words as if to note
+whether Carter himself had noticed anything unusual the night before, “we saw a
+light moving over here last night. To tell the truth, I half expected you would
+have a story to add to ours, of a second visit.”
+</p>
+
+<p>
+Carter smiled. “No objection at all. I’m simply nonplussed at the nerve of this
+fellow, coming back again. I guess you’ve heard what a narrow squeak he had
+with me. You’re welcome to go anywhere, just so long as you don’t disturb my
+study down there in the boathouse. I use that because it overlooks the bay—just
+the place to study over knotty legal problems.”
+</p>
+
+<p>
+Back of, or in front of the Carter house, according as you fancied it faced the
+bay or not, was the boathouse, built by Carter’s father, who had been a great
+yachtsman in his day and commodore of the club. His son had not gone in much
+for water sports and had converted the corner underneath a sort of observation
+tower into a sort of country law office.
+</p>
+
+<p>
+“There has always seemed to me to be something strange about that boathouse
+since the old man died,” remarked McNeill in a half whisper as we left Carter.
+“He always keeps it locked and never lets anyone go in there, although they say
+he has it fitted beautifully with hundreds of volumes of law books, too.”
+</p>
+
+<p>
+Kennedy had been climbing the hill back of the house and now paused to look
+about. Below was the Carter garage.
+</p>
+
+<p>
+“By the way,” exclaimed McNeill, as if he had at last hit on a great discovery,
+“Carter has a new chauffeur, a fellow named Wickham. I just saw him driving
+down to the village. He’s a chap that it might pay us to watch—a newcomer,
+smart as a steel trap, they say, but not much of a talker.”
+</p>
+
+<p>
+“Suppose you take that job—watch him,” encouraged Kennedy. “We can’t know too
+much about strangers here, McNeill.”
+</p>
+
+<p>
+“That’s right,” agreed the detective. “I’ll follow him back to the village and
+get a line on him.”
+</p>
+
+<p>
+“Don’t be easily discouraged,” added Kennedy, as McNeill started down the hill
+to the garage. “If he is a fox he’ll try to throw you off the trail. Hang on.”
+</p>
+
+<p>
+“What was that for?” I asked as the detective disappeared. “Did you want to get
+rid of him?”
+</p>
+
+<p>
+“Partly,” replied Craig, descending slowly, after a long survey of the
+surrounding country.
+</p>
+
+<p>
+We had reached the garage, deserted now except for our own car.
+</p>
+
+<p>
+“I’d like to investigate that tower,” remarked Kennedy with a keen look at me,
+“if it could be done without seeming to violate Mr. Carter’s hospitality.”
+</p>
+
+<p>
+“Well,” I observed, my eye catching a ladder beside the garage, “there’s a
+ladder. We can do no more than try.”
+</p>
+
+<p>
+He walked over to the automobile, took a little package out, slipped it into
+his pocket, and a few minutes later we had set the ladder up against the side
+of the boathouse farthest away from the house. It was the work of only a moment
+for Kennedy to scale it and prowl across the roof to the tower, while I stood
+guard at the foot.
+</p>
+
+<p>
+“No one has been up there recently,” he panted breathlessly as he rejoined me.
+“There isn’t a sign.”
+</p>
+
+<p>
+We took the ladder quietly back to the garage, then Kennedy led the way down
+the shore to a sort of little summerhouse cut off from the boathouse and garage
+by the trees, though over the top of a hedge one could still see the boathouse
+tower.
+</p>
+
+<p>
+We sat down, and Craig filled his lungs with the good salt air, sweeping his
+eye about the blue and green panorama as though this were a holiday and not a
+mystery case.
+</p>
+
+<p>
+“Walter,” he said at length, “I wish you’d take the car and go around to
+Verplanck’s. I don’t think you can see the tower through the trees, but I
+should like to be sure.”
+</p>
+
+<p>
+I found that it could not be seen, though I tried all over the place and got
+myself disliked by the gardener and suspected by a watchman with a dog.
+</p>
+
+<p>
+It could not have been from the tower of the boathouse that we had seen the
+light, and I hurried back to Craig to tell him so. But when I returned, I found
+that he was impatiently pacing the little rustic summerhouse, no longer
+interested in what he had sent me to find out.
+</p>
+
+<p>
+“What has happened?” I asked eagerly.
+</p>
+
+<p>
+“Just come out here and I’ll show you something,” he replied, leaving the
+summerhouse and approaching the boathouse from the other side of the hedge, on
+the beach, so that the house itself cut us off from observation from Carter’s.
+</p>
+
+<p>
+“I fixed a lens on the top of that tower when I was up there,” he explained,
+pointing up at it. “It must be about fifty feet high. From there, you see, it
+throws a reflection down to this mirror. I did it because through a skylight in
+the tower I could read whatever was written by anyone sitting at Carter’s desk
+in the corner under it.”
+</p>
+
+<p>
+“Read?” I repeated, mystified.
+</p>
+
+<p>
+“Yes, by invisible light,” he continued. “This invisible light business, you
+know, is pretty well understood by this time. I was only repeating what was
+suggested once by Professor Wood of Johns Hopkins. Practically all sources of
+light, you understand, give out more or less ultraviolet light, which plays no
+part in vision whatever. The human eye is sensitive to but few of the light
+rays that reach it, and if our eyes were constituted just the least bit
+differently we should have an entirely different set of images.
+</p>
+
+<p>
+“But by the use of various devices we can, as it were, translate these
+ultraviolet rays into terms of what the human eye can see. In order to do it,
+all the visible light rays which show us the thing as we see it—the tree green,
+the sky blue—must be cut off. So in taking an ultraviolet photograph a screen
+must be used which will be opaque to these visible rays and yet will let the
+ultraviolet rays through to form the image. That gave Professor Wood a lot of
+trouble. Glass won’t do, for glass cuts off the ultraviolet rays entirely.
+Quartz is a very good medium, but it does not cut off all the visible light. In
+fact there is only one thing that will do the work, and that is metallic
+silver.”
+</p>
+
+<p>
+I could not fathom what he was driving at, but the fascination of Kennedy
+himself was quite sufficient.
+</p>
+
+<p>
+“Silver,” he went on, “is all right if the objects can be illuminated by an
+electric spark or some other source rich in the rays. But it isn’t entirely
+satisfactory when sunlight is concerned, for various reasons that I need not
+bore you with. Professor Wood has worked out a process of depositing nickel on
+glass. That’s it up there,” he concluded, wheeling a lower reflector about
+until it caught the image of the afternoon sun thrown from the lens on the top
+of the tower.
+</p>
+
+<p>
+“You see,” he resumed, “that upper lens is concave so that it enlarges
+tremendously. I can do some wonderful tricks with that.”
+</p>
+
+<p>
+I had been lighting a cigarette and held a box of safety wind matches in my
+hand.
+</p>
+
+<p>
+“Give me that matchbox,” he asked.
+</p>
+
+<p>
+He placed it at the foot of the tower. Then he went off, I should say, without
+exaggeration, a hundred feet.
+</p>
+
+<p>
+The lettering on the matchbox could be seen in the silvered mirror, enlarged to
+such a point that the letters were plainly visible!
+</p>
+
+<p>
+“Think of the possibilities in that,” he added excitedly. “I saw them at once.
+You can read what some one is writing at a desk a hundred, perhaps two hundred
+feet away.”
+</p>
+
+<p>
+“Yes,” I cried, more interested in the practical aspects of it than in the
+mechanics and optics. “What have you found?”
+</p>
+
+<p>
+“Some one came into the boathouse while you were away,” he said. “He had a
+note. It read, ‘Those new detectives are watching everything. We must have the
+evidence. You must get those letters to-night, without fail.’”
+</p>
+
+<p>
+“Letters—evidence,” I repeated. “Who wrote it? Who received it?”
+</p>
+
+<p>
+“I couldn’t see over the hedge who had entered the boathouse, and by the time I
+got around here he was gone.”
+</p>
+
+<p>
+“Was it Wickham—or intended for Wickham?” I asked.
+</p>
+
+<p>
+Kennedy shrugged his shoulders.
+</p>
+
+<p>
+“We’ll gain nothing by staying here,” he said. “There is just one possibility
+in the case, and I can guard against that only by returning to Verplanck’s and
+getting some of that stuff I brought up here with me. Let us go.”
+</p>
+
+<p>
+Late in the afternoon though it was, after our return, Kennedy insisted on
+hurrying from Verplanck’s to the Yacht Club up the bay. It was a large
+building, extending out into the water on made land, from which ran a long,
+substantial dock. He had stopped long enough only to ask Verplanck to lend him
+the services of his best mechanician, a Frenchman named Armand.
+</p>
+
+<p>
+On the end of the yacht club dock Kennedy and Armand set up a large affair
+which looked like a mortar. I watched curiously, dividing my attention between
+them and the splendid view of the harbor which the end of the dock commanded on
+all sides.
+</p>
+
+<p>
+“What is this?” I asked finally. “Fireworks?”
+</p>
+
+<p>
+“A rocket mortar of light weight,” explained Kennedy, then dropped into French
+as he explained to Armand the manipulation of the thing.
+</p>
+
+<p>
+There was a searchlight near by on the dock.
+</p>
+
+<p>
+“You can use that?” queried Kennedy.
+</p>
+
+<p>
+“Oh, yes. Mr. Verplanck, he is vice-commodore of the club. Oh, yes, I can use
+that. Why, Monsieur?”
+</p>
+
+<p>
+Kennedy had uncovered a round brass case. It did not seem to amount to much, as
+compared to some of the complicated apparatus he had used. In it was a
+four-sided prism of glass—I should have said, cut off the corner of a huge
+glass cube.
+</p>
+
+<p>
+He handed it to us.
+</p>
+
+<p>
+“Look in it,” he said.
+</p>
+
+<p>
+It certainly was about the most curious piece of crystal gazing I had ever
+done. Turn the thing any way I pleased and I could see my face in it, just as
+in an ordinary mirror.
+</p>
+
+<p>
+“What do you call it?” Armand asked, much interested.
+</p>
+
+<p>
+“A triple mirror,” replied Kennedy, and again, half in English and half in
+French, neither of which I could follow, he explained the use of the mirror to
+the mechanician.
+</p>
+
+<p>
+We were returning up the dock, leaving Armand with instructions to be at the
+club at dusk, when we met McNeill, tired and disgusted.
+</p>
+
+<p>
+“What luck?” asked Kennedy.
+</p>
+
+<p>
+“Nothing,” he returned. “I had a ‘short’ shadow and a ‘long’ shadow at
+Wickham’s heels all day. You know what I mean. Instead of one man, two—the
+second sleuthing in the other’s tracks. If he escaped Number One, Number Two
+would take it up, and I was ready to move up into Number Two’s place. They kept
+him in sight about all the time. Not a fact. But then, of course, we don’t know
+what he was doing before we took up tailing him. Say,” he added, “I have just
+got word from an agency with which I correspond in New York that it is reported
+that a yeggman named ‘Australia Mac,’ a very daring and clever chap, has been
+attempting to dispose of some of the goods which we know have been stolen
+through one of the worst ‘fences’ in New York.”
+</p>
+
+<p>
+“Is that all?” asked Craig, with the mention of Australia Mac showing the first
+real interest yet in anything that McNeill had done since we met him the night
+before.
+</p>
+
+<p>
+“All so far. I wired for more details immediately.”
+</p>
+
+<p>
+“Do you know anything about this Australia Mac?”
+</p>
+
+<p>
+“Not much. No one does. He’s a new man, it seems, to the police here.”
+</p>
+
+<p>
+“Be here at eight o’clock, McNeill,” said Craig, as we left the club for
+Verplanck’s. “If you can find out more about this yeggman, so much the better.”
+</p>
+
+<p>
+“Have you made any progress?” asked Verplanck as we entered the estate a few
+minutes later.
+</p>
+
+<p>
+“Yes,” returned Craig, telling only enough to whet his interest. “There’s a
+clue, as I half expected, from New York, too. But we are so far away that we’ll
+have to stick to my original plan. You can trust Armand?”
+</p>
+
+<p>
+“Absolutely.”
+</p>
+
+<p>
+“Then we shall transfer our activity to the Yacht Club to-night,” was all that
+Kennedy vouchsafed.

+THE TRIPLE MIRROR</h2>
+
+<p>
+It was the regular Saturday night dance at the club, a brilliant spectacle,
+faces that radiated pleasure, gowns that for startling combinations of color
+would have shamed a Futurist, music that set the feet tapping irresistibly—a
+scene which I shall pass over because it really has no part in the story.
+</p>
+
+<p>
+The fascination of the ballroom was utterly lost on Craig. “Think of all the
+houses only half guarded about here to-night,” he mused, as we joined Armand
+and McNeill on the end of the dock. I could not help noting that that was the
+only idea which the gay, variegated, sparkling tango throng conveyed to him.
+</p>
+
+<p>
+In front of the club was strung out a long line of cars, and at the dock
+several speed boats of national and international reputation, among them the
+famous <i>Streamline II</i>, at our instant beck and call. In it Craig had
+already placed some rather bulky pieces of apparatus, as well as a brass case
+containing a second triple mirror like that which he had left with Armand.
+</p>
+
+<p>
+With McNeill, I walked back along the pier, leaving Kennedy with Armand, until
+we came to the wide porch, where we joined the wallflowers and the
+rocking-chair fleet. Mrs. Verplanck, I observed, was a beautiful dancer. I
+picked her out in the throng immediately, dancing with Carter.
+</p>
+
+<p>
+McNeill tugged at my sleeve. Without a word I saw what he meant me to see.
+Verplanck and Mrs. Hollingsworth were dancing together. Just then, across the
+porch I caught sight of Kennedy at one of the wide windows. He was trying to
+attract Verplanck’s attention, and as he did so I worked my way through the
+throng of chatting couples leaving the floor until I reached him. Verplanck,
+oblivious, finished the dance; then, seeming to recollect that he had something
+to attend to, caught sight of us, and ran off during the intermission from the
+gay crowd to which he resigned Mrs. Hollingsworth.
+</p>
+
+<p>
+“What is it?” he asked.
+</p>
+
+<p>
+“There’s that light down the bay,” whispered Kennedy.
+</p>
+
+<p>
+Instantly Verplanck forgot about the dance.
+</p>
+
+<p>
+“Where?” he asked.
+</p>
+
+<p>
+“In the same place.”
+</p>
+
+<p>
+I had not noticed, but Mrs. Verplanck, woman-like, had been able to watch
+several things at once. She had seen us and had joined us.
+</p>
+
+<p>
+“Would you like to run down there in the <i>Streamline?</i>” he asked. “It will
+only take a few minutes.”
+</p>
+
+<p>
+“Very much.”
+</p>
+
+<p>
+“What is it—that light again?” she asked, as she joined us in walking down the
+dock.
+</p>
+
+<p>
+“Yes,” answered her husband, pausing to look for a moment at the stuff Kennedy
+had left with Armand. Mrs. Verplanck leaned over the <i>Streamline</i>, turned
+as she saw me, and said: “I wish I could go with you. But evening dress is not
+the thing for a shivery night in a speed boat. I think I know as much about it
+as Mr. Verplanck. Are you going to leave Armand?”
+</p>
+
+<p>
+“Yes,” replied Kennedy, taking his place beside Verplanck, who was seated at
+the steering wheel. “Walter and McNeill, if you two will sit back there, we’re
+ready. All right.”
+</p>
+
+<p>
+Armand had cast us off and Mrs. Verplanck waved from the end of the float as
+the <i>Streamline</i> quickly shot out into the night, a buzzing, throbbing
+shape of mahogany and brass, with her exhausts sticking out like funnels and
+booming like a pipe organ. It took her only seconds to eat into the miles.
+</p>
+
+<p>
+“A little more to port,” said Kennedy, as Verplanck swung her around.
+</p>
+
+<p>
+Just then the steady droning of the engine seemed a bit less rhythmical.
+Verplanck throttled her down, but it had no effect. He shut her off. Something
+was wrong. As he crawled out into the space forward of us where the engine was,
+it seemed as if the <i>Streamline</i> had broken down suddenly and completely.
+</p>
+
+<p>
+Here we were floundering around in the middle of the bay.
+</p>
+
+<p>
+“Chuck-chuck-chuck,” came in quick staccato out of the night. It was Montgomery
+Carter, alone, on his way across the bay from the club, in his own boat.
+</p>
+
+<p>
+“Hello—Carter,” called Verplanck.
+</p>
+
+<p>
+“Hello, Verplanck. What’s the matter?”
+</p>
+
+<p>
+“Don’t know. Engine trouble of some kind. Can you give us a line?”
+</p>
+
+<p>
+“I’ve got to go down to the house,” he said, ranging up near us. “Then I can
+take you back. Perhaps I’d better get you out of the way of any other boats
+first. You don’t mind going over and then back?”
+</p>
+
+<p>
+Verplanck looked at Craig. “On the contrary,” muttered Craig, as he made fast
+the welcome line.
+</p>
+
+<p>
+The Carter dock was some three miles from the club on the other side of the
+bay. As we came up to it, Carter shut off his engine, bent over it a moment,
+made fast, and left us with a hurried, “Wait here.”
+</p>
+
+<p>
+Suddenly, overhead, we heard a peculiar whirring noise that seemed to vibrate
+through the air. Something huge, black, monster-like, slid down a board runway
+into the water, traveled a few feet, in white suds and spray, rose in the
+darkness—and was gone!
+</p>
+
+<p>
+As the thing disappeared, I thought I could hear a mocking laugh flung back at
+us.
+</p>
+
+<p>
+“What is it?” I asked, straining my eyes at what had seemed for an instant like
+a great flying fish with finny tail and huge fins at the sides and above.
+</p>
+
+<p>
+“‘Aquaero,’” quoted Kennedy quickly. “Don’t you understand—a hydroaeroplane—a
+flying boat. There are hundreds of privately owned flying boats now wherever
+there is navigable water. That was the secret of Carter’s boathouse, of the
+light we saw in the air.”
+</p>
+
+<p>
+“But this Aquaero—who is he?” persisted McNeill. “Carter—Wickham—Australia
+Mac?”
+</p>
+
+<p>
+We looked at each other blankly. No one said a word. We were captured, just as
+effectively as if we were ironed in a dungeon. There were the black water, the
+distant lights, which at any other time I should have said would have been
+beautiful.
+</p>
+
+<p>
+Kennedy had sprung into Carter’s boat.
+</p>
+
+<p>
+“The deuce,” he exclaimed. “He’s put her out of business.”
+</p>
+
+<p>
+Verplanck, chagrined, had been going over his own engine feverishly. “Do you
+see that?” he asked suddenly, holding up in the light of a lantern a little nut
+which he had picked out of the complicated machinery. “It never belonged to
+this engine. Some one placed it there, knowing it would work its way into a
+vital part with the vibration.”
+</p>
+
+<p>
+Who was the person, the only one who could have done it? The answer was on my
+lips, but I repressed it. Mrs. Verplanck herself had been bending over the
+engine when last I saw her. All at once it flashed over me that she knew more
+about the phantom bandit than she had admitted. Yet what possible object could
+she have had in putting the <i>Streamline</i> out of commission?
+</p>
+
+<p>
+My mind was working rapidly, piecing together the fragmentary facts. The remark
+of Kennedy, long before, instantly assumed new significance. What were the
+possibilities of blackmail in the right sort of evidence? The yeggman had been
+after what was more valuable than jewels—letters! Whose? Suddenly I saw the
+situation. Carter had not been robbed at all. He was in league with the robber.
+That much was a blind to divert suspicion. He was a lawyer—some one’s lawyer. I
+recalled the message about letters and evidence, and as I did so there came to
+mind a picture of Carter and the woman he had been dancing with. In return for
+his inside information about the jewels of the wealthy homes of Bluffwood, the
+yeggman was to get something of interest and importance to his client.
+</p>
+
+<p>
+The situation called for instant action. Yet what could we do, marooned on the
+other side of the bay?
+</p>
+
+<p>
+From the Club dock a long finger of light swept out into the night, plainly
+enough near the dock, but diffused and disclosing nothing in the distance.
+Armand had trained it down the bay in the direction we had taken, but by the
+time the beam reached us it was so weak that it was lost.
+</p>
+
+<p>
+Craig had leaped up on the Carter dock and was capping and uncapping with the
+brass cover the package which contained the triple mirror.
+</p>
+
+<p>
+Still in the distance I could see the wide path of light, aimed toward us, but
+of no avail.
+</p>
+
+<p>
+“What are you doing?” I asked.
+</p>
+
+<p>
+“Using the triple mirror to signal to Armand. It is something better than
+wireless. Wireless requires heavy and complicated apparatus. This is portable,
+heatless, almost weightless, a source of light depending for its power on
+another source of light at a great distance.”
+</p>
+
+<p>
+I wondered how Armand could ever detect its feeble ray.
+</p>
+
+<p>
+“Even in the case of a rolling ship,” Kennedy continued, alternately covering
+and uncovering the mirror, “the beam of light which this mirror reflects always
+goes back, unerring, to its source. It would do so from an aeroplane, so high
+in the air that it could not be located. The returning beam is invisible to
+anyone not immediately in the path of the ray, and the ray always goes to the
+observer. It is simply a matter of pure mathematics practically applied. The
+angle of incidence equals the angle of reflection. There is not a variation of
+a foot in two miles.”
+</p>
+
+<p>
+“What message are you sending him?” asked Verplanck.
+</p>
+
+<p>
+“To tell Mrs. Hollingsworth to hurry home immediately,” Kennedy replied, still
+flashing the letters according to his code.
+</p>
+
+<p>
+“Mrs. Hollingsworth?” repeated Verplanck, looking up.
+</p>
+
+<p>
+“Yes. This hydroaeroplane yeggman is after something besides jewels to-night.
+Were those letters that were stolen from you the only ones you had in the
+safe?”
+</p>
+
+<p>
+Verplanck looked up quickly. “Yes, yes. Of course.”
+</p>
+
+<p>
+“You had none from a woman—”
+</p>
+
+<p>
+“No,” he almost shouted. Of a sudden it seemed to dawn on him what Kennedy was
+driving at—the robbery of his own house with no loss except of a packet of
+letters on business, followed by the attempt on Mrs. Hollingsworth. “Do you
+think I’d keep dynamite, even in the safe?”
+</p>
+
+<p>
+To hide his confusion he had turned and was bending again over the engine.
+</p>
+
+<p>
+“How is it?” asked Kennedy, his signaling over.
+</p>
+
+<p>
+“Able to run on four cylinders and one propeller,” replied Verplanck.
+</p>
+
+<p>
+“Then let’s try her. Watch the engine. I’ll take the wheel.”
+</p>
+
+<p>
+Limping along, the engine skipping and missing, the once peerless
+<i>Streamline</i> started back across the bay. Instead of heading toward the
+club, Kennedy pointed her bow somewhere between that and Verplanck’s.
+</p>
+
+<p>
+“I wish Armand would get busy,” he remarked, after glancing now and then in the
+direction of the club. “What can be the matter?”
+</p>
+
+<p>
+“What do you mean?” I asked.
+</p>
+
+<p>
+There came the boom as if of a gun far away in the direction in which he was
+looking, then another.
+</p>
+
+<p>
+“Oh, there it is. Good fellow. I suppose he had to deliver my message to Mrs.
+Hollingsworth himself first.”
+</p>
+
+<p>
+From every quarter showed huge balls of fire, rising from the sea, as it were,
+with a brilliantly luminous flame.
+</p>
+
+<p>
+“What is it?” I asked, somewhat startled.
+</p>
+
+<p>
+“A German invention for use at night against torpedo and aeroplane attacks.
+From that mortar Armand has shot half a dozen bombs of phosphide of calcium
+which are hurled far into the darkness. They are so constructed that they float
+after a short plunge and are ignited on contact by the action of the salt water
+itself.”
+</p>
+
+<p>
+It was a beautiful pyrotechnic display, lighting up the shore and hills of the
+bay as if by an unearthly flare.
+</p>
+
+<p>
+“There’s that thing now!” exclaimed Kennedy.
+</p>
+
+<p>
+In the glow we could see a peculiar, birdlike figure flying through the air
+over toward the Hollingsworth house. It was the hydroaeroplane.
+</p>
+
+<p>
+Out from the little stretch of lawn under the accentuated shadow of the trees,
+she streaked into the air, swaying from side to side as the pilot operated the
+stabilizers on the ends of the planes to counteract the puffs of wind off the
+land.
+</p>
+
+<p>
+How could she ever be stopped?
+</p>
+
+<p>
+The <i>Streamline</i>, halting and limping, though she was, had almost crossed
+the bay before the light bombs had been fired by Armand. Every moment brought
+the flying boat nearer.
+</p>
+
+<p>
+She swerved. Evidently the pilot had seen us at last and realized who we were.
+I was so engrossed watching the thing that I had not noticed that Kennedy had
+given the wheel to Verplanck and was standing in the bow, endeavoring to sight
+what looked like a huge gun.
+</p>
+
+<p>
+In rapid succession half a dozen shots rang out. I fancied I could almost hear
+the ripping and tearing of the tough rubber-coated silken wings of the
+hydroaeroplane as the wind widened the perforation the gun had made.
+</p>
+
+<p>
+She had not been flying high, but now she swooped down almost like a gull,
+seeking to rest on the water. We were headed toward her now, and as the flying
+boat sank I saw one of the passengers rise in his seat, swing his arm, and far
+out something splashed in the bay.
+</p>
+
+<p>
+On the water, with wings helpless, the flying boat was no match for the
+<i>Streamline</i> now. She struck at an acute angle, rebounded in the air for a
+moment, and with a hiss skittered along over the waves, planing with the help
+of her exhaust under the step of the boat.
+</p>
+
+<p>
+There she was, a hull, narrow, scow-bowed, like a hydroplane, with a long
+pointed stern and a cockpit for two men, near the bow. There were two wide,
+winglike planes, on a light latticework of wood covered with silk, trussed and
+wired like a kite frame, the upper plane about five feet above the lower, which
+was level with the boat deck. We could see the eight-cylindered engine which
+drove a two-bladed wooden propeller, and over the stern were the air rudder and
+the horizontal planes. There she was, the hobbled steed now of the phantom
+bandit who had accomplished the seemingly impossible.
+</p>
+
+<p>
+In spite of everything, however, the flying boat reached the shore a trifle
+ahead of us. As she did so both figures in her jumped, and one disappeared
+quickly up the bank, leaving the other alone.
+</p>
+
+<p>
+“Verplanck, McNeill—get him,” cried Kennedy, as our own boat grated on the
+beach. “Come, Walter, we’ll take the other one.”
+</p>
+
+<p>
+The man had seen that there was no safety in flight. Down the shore he stood,
+without a hat, his hair blown pompadour by the wind.
+</p>
+
+<p>
+As we approached Carter turned superciliously, unbuttoning his bulky khaki life
+preserver jacket.
+</p>
+
+<p>
+“Well?” he asked coolly.
+</p>
+
+<p>
+Not for a moment did Kennedy allow the assumed coolness to take him back,
+knowing that Carter’s delay did not cover the retreat of the other man.
+</p>
+
+<p>
+“So,” Craig exclaimed, “you are the—the air pirate?”
+</p>
+
+<p>
+Carter disdained to reply.
+</p>
+
+<p>
+“It was you who suggested the millionaire households, full of jewels, silver
+and gold, only half guarded; you, who knew the habits of the people; you, who
+traded that information in return for another piece of thievery by your
+partner, Australia Mac—Wickham he called himself here in Bluffwood. It was
+you—-”
+</p>
+
+<p>
+A car drove up hastily, and I noted that we were still on the Hollingsworth
+estate. Mrs. Hollingsworth had seen us and had driven over toward us.
+</p>
+
+<p>
+“Montgomery!” she cried, startled.
+</p>
+
+<p>
+“Yes,” said Kennedy quickly, “air pirate and lawyer for Mrs. Verplanck in the
+suit which she contemplated bringing—”
+</p>
+
+<p>
+Mrs. Hollingsworth grew pale under the ghastly, flickering light from the bay.
+</p>
+
+<p>
+“Oh!” she cried, realizing at what Kennedy hinted, “the letters!”
+</p>
+
+<p>
+“At the bottom of the harbor, now,” said Kennedy. “Mr. Verplanck tells me he
+has destroyed his. The past is blotted out as far as that is concerned. The
+future is—for you three to determine. For the present I’ve caught a yeggman and
+a blackmailer.”

+THE WIRELESS WIRETAPPERS</h2>
+
+<p>
+Kennedy did not wait at Bluffwood longer than was necessary. It was easy enough
+now to silence Montgomery Carter, and the reconciliation of the Verplancks was
+assured. In the <i>Star</i> I made the case appear at the time to involve
+merely the capture of Australia Mac.
+</p>
+
+<p>
+When I dropped into the office the next day as usual, I found that I had
+another assignment that would take me out on Long Island. The story looked
+promising and I was rather pleased to get it.
+</p>
+
+<p>
+“Bound for Seaville, I’ll wager,” sounded a familiar voice in my ear, as I
+hurried up to the train entrance at the Long Island corner of the Pennsylvania
+Station.
+</p>
+
+<p>
+I turned quickly, to find Kennedy just behind me, breathless and perspiring.
+</p>
+
+<p>
+“Er—yes,” I stammered in surprise at seeing him so unexpectedly, “but where did
+you come from? How did you know?”
+</p>
+
+<p>
+“Let me introduce Mr. Jack Waldon,” he went on, as we edged our way toward the
+gate, “the brother of Mrs. Tracy Edwards, who disappeared so strangely from the
+houseboat <i>Lucie</i> last night at Seaville. That is the case you’re going to
+write up, isn’t it?”
+</p>
+
+<p>
+It was then for the first time that I noticed the excited young man beside
+Kennedy was really his companion.
+</p>
+
+<p>
+I shook hands with Waldon, who gave me a grip that was both a greeting and an
+added impulse in our general direction through the wicket.
+</p>
+
+<p>
+“Might have known the <i>Star</i> would assign you to this Edwards case,”
+panted Kennedy, mopping his forehead, for the heat in the terminal was
+oppressive and the crowd, though not large, was closely packed. “Mr. Jameson is
+my right-hand man,” he explained to Waldon, taking us each by the arm and
+urging us forward. “Waldon was afraid we might miss the train or I should have
+tried to get you, Walter, at the office.”
+</p>
+
+<p>
+It was all done so suddenly that they quite took away what remaining breath I
+had, as we settled ourselves to swelter in the smoker instead of in the
+concourse. I did not even protest at the matter-of-fact assurance with which
+Craig assumed that his deduction as to my destination was correct.
+</p>
+
+<p>
+Waldon, a handsome young fellow in a flannel suit and yachting cap somewhat the
+worse for his evidently perturbed state of mind, seemed to eye me for the
+moment doubtfully, in spite of Kennedy’s cordial greeting.
+</p>
+
+<p>
+“I’ve had all the first editions of the evening papers,” I hinted as we sped
+through the tunnel, “but the stories seemed to be quite the same—pretty meager
+in details.”
+</p>
+
+<p>
+“Yes,” returned Waldon with a glance at Kennedy, “I tried to keep as much out
+of the papers as I could just now for Lucie’s sake.”
+</p>
+
+<p>
+“You needn’t fear Jameson,” remarked Kennedy.
+</p>
+
+<p>
+He fumbled in his pocket, then paused a moment and shot a glance of inquiry at
+Waldon, who nodded a mute acquiescence to him.
+</p>
+
+<p>
+“There seem to have been a number of very peculiar disappearances lately,”
+resumed Kennedy, “but this case of Mrs. Edwards is by far the most
+extraordinary. Of course the <i>Star</i> hasn’t had that—yet,” he concluded,
+handing me a sheet of notepaper.
+</p>
+
+<p>
+“Mr. Waldon didn’t give it out, hoping to avoid scandal.”
+</p>
+
+<p>
+I took the paper and read eagerly, in a woman’s hand:
+</p>
+
+<p class="p2">
+“M<small>Y</small> D<small>EAR</small> M<small>ISS</small> F<small>OX</small>:
+I have been down here at Seaville on our houseboat, the <i>Lucie</i>, for
+several days for a purpose which now is accomplished.
+</p>
+
+<p>
+“Already I had my suspicions of you, from a source which I need not name.
+Therefore, when the <i>Kronprinz</i> got into wireless communication with the
+station at Seaville I determined through our own wireless on the <i>Lucie</i>
+to overhear whether there would be any exchange of messages between my husband
+and yourself.
+</p>
+
+<p>
+“I was able to overhear the whole thing and I want you to know that your secret
+is no longer a secret from me, and that I have already told Mr. Edwards that I
+know it. You ruin his life by your intimacy which you seem to want to keep up,
+although you know you have no right to do it, but you shall not ruin mine.
+</p>
+
+<p>
+“I am thoroughly disillusioned now. I have not decided on what steps to take,
+but—”
+</p>
+
+<p class="p2">
+Only a casual glance was necessary to show me that the writing seemed to grow
+more and more weak as it progressed, and the note stopped abruptly, as if the
+writer had been suddenly interrupted or some new idea had occurred to her.
+</p>
+
+<p>
+Hastily I tried to figure it out. Lucie Waldon, as everybody knew, was a famous
+beauty, a marvel of charm and daintiness, slender, with big, soulful, wistful
+eyes. Her marriage to Tracy Edwards, the wealthy plunger and stockbroker, had
+been a great social event the year before, and it was reputed at the time that
+Edwards had showered her with jewels and dresses to the wonder and talk even of
+society.
+</p>
+
+<p>
+As for Valerie Fox, I knew she had won quick recognition and even fame as a
+dancer in New York during the previous winter, and I recalled reading three or
+four days before that she had just returned on the <i>Kronprinz</i> from a trip
+abroad.
+</p>
+
+<p>
+“I don’t suppose you have had time to see Miss Fox,” I remarked. “Where is
+she?”
+</p>
+
+<p>
+“At Beach Park now, I think,” replied Waldon, “a resort a few miles nearer the
+city on the south shore, where there is a large colony of actors.”
+</p>
+
+<p>
+I handed back the letter to Kennedy.
+</p>
+
+<p>
+“What do you make of it?” he asked, as he folded it up and put it back into his
+pocket.
+</p>
+
+<p>
+“I hardly know what to say,” I replied. “Of course there have been rumors, I
+believe, that all was not exactly like a honeymoon still with the Tracy
+Edwardses.”
+</p>
+
+<p>
+“Yes,” returned Waldon slowly, “I know myself that there has been some trouble,
+but nothing definite until I found this letter last night in my sister’s room.
+She never said anything about it either to mother or myself. They haven’t been
+much together during the summer, and last night when she disappeared Tracy was
+in the city. But I hadn’t thought much about it before, for, of course, you
+know he has large financial interests that make him keep in pretty close touch
+with New York and this summer hasn’t been a particularly good one on the stock
+exchange.”
+</p>
+
+<p>
+“And,” I put in, “a plunger doesn’t always make the best of husbands. Perhaps
+there is temperament to be reckoned with here.”
+</p>
+
+<p>
+“There seem to be a good many things to be reckoned with,” Craig considered.
+“For example, here’s a houseboat, the <i>Lucie</i>, a palatial affair, cruising
+about aimlessly, with a beautiful woman on it. She gives a little party, in the
+absence of her husband, to her brother, his fiancée and her mother, who visit
+her from his yacht, the <i>Nautilus</i>. They break up, those living on the
+<i>Lucie</i> going to their rooms and the rest back to the yacht, which is
+anchored out further in the deeper water of the bay.
+</p>
+
+<p>
+“Some time in the middle of the night her maid, Juanita, finds that she is not
+in her room. Her brother is summoned back from his yacht and finds that she has
+left this pathetic, unfinished letter. But otherwise there is no trace of her.
+Her husband is notified and hurries out there, but he can find no clue.
+Meanwhile, Mr. Waldon, in despair, hurries down to the city to engage me
+quietly.”
+</p>
+
+<p>
+“You remember I told you,” suggested Waldon, “that my sister hadn’t been
+feeling well for several days. In fact it seemed that the sea air wasn’t doing
+her much good, and some one last night suggested that she try the mountains.”
+</p>
+
+<p>
+“Had there been anything that would foreshadow the—er—disappearance?” asked
+Kennedy.
+</p>
+
+<p>
+“Only as I say, that for two or three days she seemed to be listless, to be
+sinking by slow and easy stages into a sort of vacant, moody state of ill
+health.”
+</p>
+
+<p>
+“She had a doctor, I suppose?” I asked.
+</p>
+
+<p>
+“Yes, Dr. Jermyn, Tracy’s own personal physician came down from the city
+several days ago.”
+</p>
+
+<p>
+“What did he say?”
+</p>
+
+<p>
+“He simply said that it was congestion of the lungs. As far as he could see
+there was no apparent cause for it. I don’t think he was very enthusiastic
+about the mountain air idea. The fact is he was like a good many doctors under
+the circumstances, noncommittal—wanted her under observation, and all that sort
+of thing.”
+</p>
+
+<p>
+“What’s your opinion?” I pressed Craig. “Do you think she has run away?”
+</p>
+
+<p>
+“Naturally, I’d rather not attempt to say yet,” Craig replied cautiously. “But
+there are several possibilities. Yes, she might have left the houseboat in some
+other boat, of course. Then there is the possibility of accident. It was a hot
+night. She might have been leaning from the window and have lost her balance. I
+have even thought of drugs, that she might have taken something in her
+despondency and have fallen overboard while under the influence of it. Then, of
+course, there are the two deductions that everyone has made already—either
+suicide or murder.”
+</p>
+
+<p>
+Waldon had evidently been turning something over in his mind.
+</p>
+
+<p>
+“There was a wireless outfit aboard the houseboat,” he ventured at length.
+</p>
+
+<p>
+“What of that?” I asked, wondering why he was changing the subject so abruptly.
+</p>
+
+<p>
+“Why, only this,” he replied. “I have been reading about wireless a good deal
+lately, and if the theories of some scientists are correct, the wireless age is
+not without its dangers as well as its wonders. I recall reading not long ago
+of a German professor who says there is no essential difference between
+wireless waves and the X-rays, and we know the terrible physical effects of
+X-rays. I believe he estimated that only one three hundred millionth part of
+the electrical energy generated by sending a message from one station to
+another near by is actually used up in transmitting the message. The rest is
+dispersed in the atmosphere. There must be a good deal of such stray electrical
+energy about Seaville. Isn’t it possible that it might hit some one somewhere
+who was susceptible?”
+</p>
+
+<p>
+Kennedy said nothing. Waldon’s was at least a novel idea, whether it was
+plausible or not. The only way to test it out, as far as I could determine, was
+to see whether it fitted with the facts after a careful investigation of the
+case itself.
+</p>
+
+<p>
+It was still early in the day and the trains were not as crowded as they would
+be later. Consequently our journey was comfortable enough and we found
+ourselves at last at the little vine-covered station at Seaville.
+</p>
+
+<p>
+One could almost feel that the gay summer colony was in a state of subdued
+excitement. As we left the quaint station and walked down the main street to
+the town wharf where we expected some one would be waiting for us, it seemed as
+if the mysterious disappearance of the beautiful Mrs. Edwards had put a damper
+on the life of the place. In the hotels there were knots of people evidently
+discussing the affair, for as we passed we could tell by their faces that they
+recognized us. One or two bowed and would have joined us, if Waldon had given
+any encouragement. But he did not stop, and we kept on down the street quickly.
+</p>
+
+<p>
+I myself began to feel the spell of mystery about the case as I had not felt it
+among the distractions of the city. Perhaps I imagined it, but there even
+seemed to be something strange about the houseboat which we could descry at
+anchor far down the bay as we approached the wharf.
+</p>
+
+<p>
+We were met, as Waldon had arranged, by a high-powered runabout, the tender to
+his own yacht, a slim little craft of mahogany and brass, driven like an
+automobile, and capable of perhaps twenty-five or thirty miles an hour. We
+jumped in and were soon skimming over the waters of the bay like a skipping
+stone.
+</p>
+
+<p>
+It was evident that Waldon was much relieved at having been able to bring
+assistance, in which he had as much confidence as he reposed in Kennedy. At any
+rate it was something to be nearing the scene of action again.
+</p>
+
+<p>
+The <i>Lucie</i> was perhaps seventy feet long and a most attractive craft,
+with a hull yachty in appearance and of a type which could safely make long
+runs along the coast, a stanch, seaworthy boat, of course without the speed of
+the regularly designed yacht, but more than making up in comfort for those on
+board what was lost in that way. Waldon pointed out with obvious pride his own
+trim yacht swinging gracefully at anchor a half mile or so away.
+</p>
+
+<p>
+As we approached the houseboat I looked her over carefully. One of the first
+things I noticed was that there rose from the roof the primitive inverted V
+aërial of a wireless telegraph. I thought immediately of the unfinished letter
+and its contents, and shaded my eyes as I took a good look at the powerful
+transatlantic station on the spit of sand perhaps three or four miles distant,
+with its tall steel masts of the latest inverted L type and the cluster of
+little houses below, in which the operators and the plant were.
+</p>
+
+<p>
+Waldon noticed what I was looking at, and remarked, “It’s a wonderful
+station—and well worth a visit, if you have the time—one of the most powerful
+on the coast, I understand.”
+</p>
+
+<p>
+“How did the <i>Lucie</i> come to be equipped with wireless?” asked Craig
+quickly. “It’s a little unusual for a private boat.”
+</p>
+
+<p>
+“Mr. Edwards had it done when she was built,” explained Waldon. “His idea was
+to use it to keep in touch with the stock market on trips.”
+</p>
+
+<p>
+“And it has proved effective?” asked Craig.
+</p>
+
+<p>
+“Oh, yes—that is, it was all right last winter when he went on a short cruise
+down in Florida. This summer he hasn’t been on the boat long enough to use it
+much.”
+</p>
+
+<p>
+“Who operates it?”
+</p>
+
+<p>
+“He used to hire a licensed operator, although I believe the engineer,
+Pedersen, understands the thing pretty well and could use it if necessary.”
+</p>
+
+<p>
+“Do you think it was Pedersen who used it for Mrs. Edwards?” asked Kennedy.
+</p>
+
+<p>
+“I really don’t know,” confessed Waldon. “Pedersen denies absolutely that he
+has touched the thing for weeks. I want you to quiz him. I wasn’t able to get
+him to admit a thing.”

+<h2><a name="chap08"></a>CHAPTER VIII<br/>
+THE HOUSEBOAT MYSTERY</h2>
+
+<p>
+We had by this time swung around to the side of the houseboat. I realized as we
+mounted the ladder that the marine gasoline engine had materially changed the
+old-time houseboat from a mere scow or barge with a low flat house on it,
+moored in a bay or river, and only with difficulty and expense towed from one
+place to another. Now the houseboat was really a fair-sized yacht.
+</p>
+
+<p>
+The <i>Lucie</i> was built high in order to give plenty of accommodation for
+the living quarters. The staterooms, dining rooms and saloon were really rooms,
+with seven or eight feet of head room, and furnished just as one would find in
+a tasteful and expensive house.
+</p>
+
+<p>
+Down in the hull, of course, was the gasoline motor which drove the propeller,
+so that when the owner wanted a change of scene all that was necessary was to
+get up anchor, start the motor and navigate the yacht-houseboat to some other
+harbor.
+</p>
+
+<p>
+Edwards himself met us on the deck. He was a tall man, with a red face, a man
+of action, of outdoor life, apparently a hard worker and a hard player. It was
+quite evident that he had been waiting for the return of Waldon anxiously.
+</p>
+
+<p>
+“You find us considerably upset, Professor Kennedy,” he greeted Craig, as his
+brother-in-law introduced us.
+</p>
+
+<p>
+Edwards turned and led the way toward the saloon. As he entered and bade us be
+seated in the costly cushioned wicker chairs I noticed how sumptuously it was
+furnished, and particularly its mechanical piano, its phonograph and the
+splendid hardwood floor which seemed to invite one to dance in the cool breeze
+that floated across from one set of open windows to the other. And yet in spite
+of everything, there was that indefinable air of something lacking, as in a
+house from which the woman is gone.
+</p>
+
+<p>
+“You were not here last night, I understand,” remarked Kennedy, taking in the
+room at a glance.
+</p>
+
+<p>
+“Unfortunately, no,” replied Edwards, “Business has kept me with my nose pretty
+close to the grindstone this summer. Waldon called me up in the middle of the
+night, however, and I started down in my car, which enabled me to get here
+before the first train. I haven’t been able to do a thing since I got here
+except just wait—wait—wait. I confess that I don’t know what else to do. Waldon
+seemed to think we ought to have some one down here—and I guess he was right.
+Anyhow, I’m glad to see you.”
+</p>
+
+<p>
+I watched Edwards keenly. For the first time I realized that I had neglected to
+ask Waldon whether he had seen the unfinished letter. The question was
+unnecessary. It was evident that he had not.
+</p>
+
+<p>
+“Let me see, Waldon, if I’ve got this thing straight,” Edwards went on, pacing
+restlessly up and down the saloon. “Correct me if I haven’t. Last night, as I
+understand it, there was a sort of little family party here, you and Miss
+Verrall and your mother from the <i>Nautilus</i>, and Mrs. Edwards and Dr.
+Jermyn.”
+</p>
+
+<p>
+“Yes,” replied Waldon with, I thought, a touch of defiance at the words “family
+party.” He paused as if he would have added that the <i>Nautilus</i> would have
+been more congenial, anyhow, then added, “We danced a little bit, all except
+Lucie. She said she wasn’t feeling any too well.”
+</p>
+
+<p>
+Edwards had paused by the door. “If you’ll excuse me a minute,” he said, “I’ll
+call Jermyn and Mrs. Edwards’ maid, Juanita. You ought to go over the whole
+thing immediately, Professor Kennedy.”
+</p>
+
+<p>
+“Why didn’t you say anything about the letter to him?” asked Kennedy under his
+breath.
+</p>
+
+<p>
+“What was the use?” returned Waldon. “I didn’t know how he’d take it. Besides,
+I wanted your advice on the whole thing. Do you want to show it to him?”
+</p>
+
+<p>
+“Perhaps it’s just as well,” ruminated Kennedy. “It may be possible to clear
+the thing up without involving anybody’s name. At any rate, some one is coming
+down the passage this way.”
+</p>
+
+<p>
+Edwards entered with Dr. Jermyn, a clean-shaven man, youthful in appearance,
+yet approaching middle age. I had heard of him before. He had studied several
+years abroad and had gained considerable reputation since his return to
+America.
+</p>
+
+<p>
+Dr. Jermyn shook hands with us cordially enough, made some passing comment on
+the tragedy, and stood evidently waiting for us to disclose our hands.
+</p>
+
+<p>
+“You have been Mrs. Edwards’ physician for some time, I believe?” queried
+Kennedy, fencing for an opening.
+</p>
+
+<p>
+“Only since her marriage,” replied the doctor briefly.
+</p>
+
+<p>
+“She hadn’t been feeling well for several days, had she?” ventured Kennedy
+again.
+</p>
+
+<p>
+“No,” replied Dr. Jermyn quickly. “I doubt whether I can add much to what you
+already know. I suppose Mr. Waldon has told you about her illness. The fact is,
+I suppose her maid Juanita will be able to tell you really more than I can.”
+</p>
+
+<p>
+I could not help feeling that Dr. Jermyn showed a great deal of reluctance in
+talking.
+</p>
+
+<p>
+“You have been with her several days, though, haven’t you?”
+</p>
+
+<p>
+“Four days, I think. She was complaining of feeling nervous and telegraphed me
+to come down here. I came prepared to stay over night, but Mr. Edwards happened
+to run down that day, too, and he asked me if I wouldn’t remain longer. My
+practice in the summer is such that I can easily leave it with my assistant in
+the city, so I agreed. Really, that is about all I can say. I don’t know yet
+what was the matter with Mrs. Edwards, aside from the nervousness which seemed
+to be of some time standing.”
+</p>
+
+<p>
+He stood facing us, thoughtfully stroking his chin, as a very pretty and petite
+maid nervously entered and stood facing us in the doorway.
+</p>
+
+<p>
+“Come in, Juanita,” encouraged Edwards. “I want you to tell these gentlemen
+just what you told me about discovering that Madame had gone—and anything else
+that you may recall now.”
+</p>
+
+<p>
+“It was Juanita who discovered that Madame was gone, you know,” put in Waldon.
+</p>
+
+<p>
+“How did you discover it?” prompted Craig.
+</p>
+
+<p>
+“It was very hot,” replied the maid, “and often on hot nights I would come in
+and fan Madame since she was so wakeful. Last night I went to the door and
+knocked. There was no reply. I called to her, ‘Madame, madame.’ Still there was
+no answer. The worst I supposed was that she had fainted. I continued to call.”
+</p>
+
+<p>
+“The door was locked?” inquired Kennedy.
+</p>
+
+<p>
+“Yes, sir. My call aroused the others on the boat. Dr. Jermyn came and he broke
+open the door with his shoulder. But the room was empty. Madame was gone.”
+</p>
+
+<p>
+“How about the windows?” asked Kennedy.
+</p>
+
+<p>
+“Open. They were always open these nights. Sometimes Madame would sit by the
+window when there was not much breeze.”
+</p>
+
+<p>
+“I should like to see the room,” remarked Craig, with an inquiring glance at
+Edwards.
+</p>
+
+<p>
+“Certainly,” he answered, leading the way down a corridor.
+</p>
+
+<p>
+Mrs. Edwards’ room was on the starboard side, with wide windows instead of
+portholes. It was furnished magnificently and there was little about it that
+suggested the nautical, except the view from the window.
+</p>
+
+<p>
+“The bed had not been slept in,” Edwards remarked as we looked about curiously.
+</p>
+
+<p>
+Kennedy walked over quickly to the wide series of windows before which was a
+leather-cushioned window seat almost level with the window, several feet above
+the level of the water. It was by this window, evidently, that Juanita meant
+that Mrs. Edwards often sat. It was a delightful position, but I could readily
+see that it would be comparatively easy for anyone accidentally or purposely to
+fall.
+</p>
+
+<p>
+“I think myself,” Waldon remarked to Kennedy, “that it must have been from the
+open window that she made her way to the outside. It seems that all agree that
+the door was locked, while the window was wide open.”
+</p>
+
+<p>
+“There had been no sound—no cry to alarm you?” shot out Kennedy suddenly to
+Juanita.
+</p>
+
+<p>
+“No, sir, nothing. I could not sleep myself, and I thought of Madame.”
+</p>
+
+<p>
+“You heard nothing?” he asked of Dr. Jermyn.
+</p>
+
+<p>
+“Nothing until I heard the maid call,” he replied briefly.
+</p>
+
+<p>
+Mentally I ran over again Kennedy’s first list of possibilities—taken off by
+another boat, accident, drugs, suicide, murder.
+</p>
+
+<p>
+Was there, I asked myself, sufficient reason for suicide? The letter seemed to
+me to show too proud a spirit for that. In fact the last sentence seemed to
+show that she was contemplating the surest method of revenge, rather than
+surrender. As for accident, why should a person fall overboard from a large
+houseboat into a perfectly calm harbor? Then, too, there had been no outcry.
+Somehow, I could not seem to fit any of the theories in with the facts.
+Evidently it was like many another case, one in which we, as yet, had
+insufficient data for a conclusion.
+</p>
+
+<p>
+Suddenly I recalled the theory that Waldon himself had advanced regarding the
+wireless, either from the boat itself or from the wireless station. For the
+moment, at least, it seemed plausible that she might have been seated at the
+window, that she might have been affected by escaped wireless, or by
+electrolysis. I knew that some physicians had described a disease which they
+attributed to wireless, a sort of anemia with a marked diminution in the number
+of red corpuscles in the blood, due partly to the over etherization of the air
+by reason of the alternating currents used to generate the waves.
+</p>
+
+<p>
+“I should like now to inspect the little wireless plant you have here on the
+<i>Lucie</i>,” remarked Kennedy. “I noticed the mast as we were approaching a
+few minutes ago.”
+</p>
+
+<p>
+I had turned at the sound of his voice in time to catch Edwards and Dr. Jermyn
+eyeing each other furtively. Did they know about the letter, after all, I
+wondered? Was each in doubt about just how much the other knew?
+</p>
+
+<p>
+There was no time to pursue these speculations. “Certainly,” agreed Mr. Edwards
+promptly, leading the way.
+</p>
+
+<p>
+Kennedy seemed keenly interested in inspecting the little wireless plant, which
+was of a curious type and not exactly like any that I had seen before.
+</p>
+
+<p>
+“Wireless apparatus,” he remarked, as he looked it over, “is divided into three
+parts, the source of power whether battery or dynamo, the making and sending of
+wireless waves, including the key, spark, condenser and tuning coil, and the
+receiving apparatus, head telephones, antennae, ground and detector.”
+</p>
+
+<p>
+Pedersen, the engineer, came in while we were looking the plant over, but
+seemed uncommunicative to all Kennedy’s efforts to engage him in conversation.
+</p>
+
+<p>
+“I see,” remarked Kennedy, “that it is a very compact system with facilities
+for a quick change from one wave length to another.”
+</p>
+
+<p>
+“Yes,” grunted Pedersen, as averse to talking, evidently, as others on the
+<i>Lucie</i>.
+</p>
+
+<p>
+“Spark gap, quenched type,” I heard Kennedy mutter almost to himself, with a
+view to showing Pedersen that he knew something about it. “Break system
+relay—operator can overhear any interference while transmitting—transformation
+by a single throw of a six-point switch which tunes the oscillating and open
+circuits to resonance. Very clever—very efficient. By the way, Pedersen, are
+you the only person aboard who can operate this?”
+</p>
+
+<p>
+“How should I know?” he answered almost surlily.
+</p>
+
+<p>
+“You ought to know, if anybody,” answered Kennedy unruffled. “I know that it
+has been operated within the past few days.”
+</p>
+
+<p>
+Pedersen shrugged his shoulders. “You might ask the others aboard,” was all he
+said. “Mr. Edwards pays me to operate it only for himself, when he has no other
+operator.”
+</p>
+
+<p>
+Kennedy did not pursue the subject, evidently from fear of saying too much just
+at present.
+</p>
+
+<p>
+“I wonder if there is anyone else who could have operated it,” said Waldon, as
+we mounted again to the deck.
+</p>
+
+<p>
+“I don’t know,” replied Kennedy, pausing on the way up. “You haven’t a wireless
+on the <i>Nautilus</i>, have you?”
+</p>
+
+<p>
+Waldon shook his head. “Never had any particular use for it myself,” he
+answered.
+</p>
+
+<p>
+“You say that Miss Verrall and her mother have gone back to the city?” pursued
+Kennedy, taking care that as before the others were out of earshot.
+</p>
+
+<p>
+“Yes.”
+</p>
+
+<p>
+“I’d like to stay with you tonight, then,” decided Kennedy. “Might we go over
+with you now? There doesn’t seem to be anything more I can do here, unless we
+get some news about Mrs. Edwards.”
+</p>
+
+<p>
+Waldon seemed only too glad to agree, and no one on the <i>Lucie</i> insisted
+on our staying.
+</p>
+
+<p>
+We arrived at the <i>Nautilus</i> a few minutes later, and while we were
+lunching Kennedy dispatched the tender to the Marconi station with a note.
+</p>
+
+<p>
+It was early in the afternoon when the tender returned with several packages
+and coils of wire. Kennedy immediately set to work on the <i>Nautilus</i>
+stretching out some of the wire.
+</p>
+
+<p>
+“What is it you are planning?” asked Waldon, to whom every action of Kennedy
+seemed to be a mystery of the highest interest.
+</p>
+
+<p>
+“Improvising my own wireless,” he replied, not averse to talking to the young
+man to whom he seemed to have taken a fancy. “For short distances, you know, it
+isn’t necessary to construct an aërial pole or even to use outside wires to
+receive messages. All that is needed is to use just a few wires stretched
+inside a room. The rest is just the apparatus.”
+</p>
+
+<p>
+I was quite as much interested as Waldon. “In wireless,” he went on, “the
+signals are not sent in one direction, but in all, so that a person within
+range of the ethereal disturbance can get them if only he has the necessary
+receiving apparatus. This apparatus need not be so elaborate and expensive as
+used to be thought needful if a sensitive detector is employed, and I have sent
+over to the station for a new piece of apparatus which I knew they had in
+almost any Marconi station. Why, I’ve got wireless signals using only twelve
+feet of number eighteen copper wire stretched across a room and grounded with a
+water pipe. You might even use a wire mattress on an iron bedstead.”
+</p>
+
+<p>
+“Can’t they find out by—er, interference?” I asked, repeating the term I had so
+often heard.
+</p>
+
+<p>
+Kennedy laughed. “No, not for radio apparatus which merely receives radiograms
+and is not equipped for sending. I am setting up only one side of a wireless
+outfit here. All I want to do is to hear what is being said. I don’t care about
+saying anything.”
+</p>
+
+<p>
+He unwrapped another package which had been loaned to him by the radio station
+and we watched him curiously as he tested it and set it up. Some parts of it I
+recognized such as the very sensitive microphone, and another part I could have
+sworn was a phonograph cylinder, though Craig was so busy testing his apparatus
+that now we could not ask questions.
+</p>
+
+<p>
+It was late in the afternoon when he finished, and we had just time to run up
+to the dock at Seaville and stop off at the <i>Lucie</i> to see if anything had
+happened in the intervening hours before dinner. There was nothing, except that
+I found time to file a message to the <i>Star</i> and meet several fellow
+newspaper men who had been sent down by other papers on the chance of picking
+up a good story.
+</p>
+
+<p>
+We had the <i>Nautilus</i> to ourselves, and as she was a very comfortable
+little craft, we really had a very congenial time, a plunge over her side, a
+good dinner, and then a long talk out on deck under the stars, in which we went
+over every phase of the case. As we discussed it, Waldon followed keenly, and
+it was quite evident from his remarks that he had come to the conclusion that
+Dr. Jermyn at least knew more than he had told about the case.
+</p>
+
+<p>
+Still, the day wore away with no solution yet of the mystery.

+<h2><a name="chap09"></a>CHAPTER IX<br/>
+THE RADIO DETECTIVE</h2>
+
+<p>
+It was early the following morning when a launch drew up beside the
+<i>Nautilus</i>. In it were Edwards and Dr. Jermyn, wildly excited.
+</p>
+
+<p>
+“What’s the matter?” called out Waldon.
+</p>
+
+<p>
+“They—they have found the body,” Edwards blurted out.
+</p>
+
+<p>
+Waldon paled and clutched the rail. He had thought the world of his sister, and
+not until the last moment had he given up hope that perhaps she might be found
+to have disappeared in some other way than had become increasingly evident.
+</p>
+
+<p>
+“Where?” cried Kennedy. “Who?”
+</p>
+
+<p>
+“Over on Ten Mile Beach,” answered Edwards. “Some fishermen who had been out on
+a cruise and hadn’t heard the story. They took the body to town, and there it
+was recognized. They sent word out to us immediately.”
+</p>
+
+<p>
+Waldon had already spun the engine of his tender, which was about the fastest
+thing afloat about Seaville, had taken Edwards over, and we were off in a cloud
+of spray, the nose of the boat many inches above the surface of the water.
+</p>
+
+<p>
+In the little undertaking establishment at Seaville lay the body of the
+beautiful young matron about whom so much anxiety had been felt. I could not
+help thinking what an end was this for the incomparable beauty. At the very
+height of her brief career the poor little woman’s life had been suddenly
+snuffed out. But by what? The body had been found, but the mystery had been far
+from solved.
+</p>
+
+<p>
+As Kennedy bent over the body, I heard him murmur to himself, “She had
+everything—everything except happiness.”
+</p>
+
+<p>
+“Was it drowning that caused her death?” asked Kennedy of the local doctor, who
+also happened to be coroner and had already arrived on the scene.
+</p>
+
+<p>
+The doctor shook his head. “I don’t know,” he said doubtfully. “There was
+congestion of the lungs—but I—I can’t say but what she might have been dead
+before she fell or was thrown into the water.”
+</p>
+
+<p>
+Dr. Jermyn stood on one side, now and then putting in a word, but for the most
+part silent unless spoken to. Kennedy, however, was making a most minute
+examination.
+</p>
+
+<p>
+As he turned the beautiful head, almost reverently, he saw something that
+evidently attracted his attention. I was standing next to him and, between us,
+I think we cut off the view of the others. There on the back of the neck,
+carefully, had been smeared something transparent, almost skin-like, which had
+easily escaped the attention of the rest.
+</p>
+
+<p>
+Kennedy tried to pick it off, but only succeeded in pulling off a very minute
+piece to which the flesh seemed to adhere.
+</p>
+
+<p>
+“That’s queer,” he whispered to me. “Water, naturally, has no effect on it,
+else it would have been washed off long before. Walter,” he added, “just slip
+across the street quietly to the drug store and get me a piece of gauze soaked
+with acetone.”
+</p>
+
+<p>
+As quickly and unostentatiously as I could I did so and handed him the wet
+cloth, contriving at the same time to add Waldon to our barrier, for I could
+see that Kennedy was anxious to be observed as little as possible.
+</p>
+
+<p>
+“What is it?” I whispered, as he rubbed the transparent skin-like stuff off,
+and dropped the gauze into his pocket.
+</p>
+
+<p>
+“A sort of skin varnish,” he remarked under his breath, “waterproof and so
+adhesive that it resists pulling off even with a knife without taking the
+cuticle with it.”
+</p>
+
+<p>
+Beneath, as the skin varnish slowly dissolved under his gentle rubbing, he had
+disclosed several very small reddish spots, like little cuts that had been made
+by means of a very sharp instrument. As he did so, he gave them a hasty glance,
+turned the now stony beautiful head straight again, stood up, and resumed his
+talk with the coroner, who was evidently getting more and more bewildered by
+the case.
+</p>
+
+<p>
+Edwards, who had completed the arrangements with the undertaker for the care of
+the body as soon as the coroner released it, seemed completely unnerved.
+</p>
+
+<p>
+“Jermyn,” he said to the doctor, as he turned away and hid his eyes, “I can’t
+stand this. The undertaker wants some stuff from the—er—boat,” his voice broke
+over the name which had been hers. “Will you get it for me? I’m going up to a
+hotel here, and I’ll wait for you there. But I can’t go out to the boat—yet.”
+</p>
+
+<p>
+“I think Mr. Waldon will be glad to take you out in his tender,” suggested
+Kennedy. “Besides, I feel that I’d like a little fresh air as a bracer, too,
+after such a shock.”
+</p>
+
+<p>
+“What were those little cuts?” I asked as Waldon and Dr. Jermyn preceded us
+through the crowd outside to the pier.
+</p>
+
+<p>
+“Some one,” he answered in a low tone, “has severed the pneumogastric nerves.”
+</p>
+
+<p>
+“The pneumogastric nerves?” I repeated.
+</p>
+
+<p>
+“Yes, the vagus or wandering nerve, the so-called tenth cranial nerve. Unlike
+the other cranial nerves, which are concerned with the special senses or
+distributed to the skin and muscles of the head and neck, the vagus, as its
+name implies, strays downward into the chest and abdomen supplying branches to
+the throat, lungs, heart and stomach and forms an important connecting link
+between the brain and the sympathetic nervous system.”
+</p>
+
+<p>
+We had reached the pier, and a nod from Kennedy discouraged further
+conversation on the subject.
+</p>
+
+<p>
+A few minutes later we had reached the <i>Lucie</i> and gone up over her side.
+Kennedy waited until Jermyn had disappeared into the room of Mrs. Edwards to
+get what the undertaker had desired. A moment and he had passed quietly into
+Dr. Jermyn’s own room, followed by me. Several quick glances about told him
+what not to waste time over, and at last his eye fell on a little portable case
+of medicines and surgical instruments. He opened it quickly and took out a
+bottle of golden yellow liquid.
+</p>
+
+<p>
+Kennedy smelled it, then quickly painted some on the back of his hand. It dried
+quickly, like an artificial skin. He had found a bottle of skin varnish in Dr.
+Jermyn’s own medicine chest!
+</p>
+
+<p>
+We hurried back to the deck, and a few minutes later the doctor appeared with a
+large package.
+</p>
+
+<p>
+“Did you ever hear of coating the skin by a substance which is impervious to
+water, smooth and elastic?” asked Kennedy quietly as Waldon’s tender sped along
+back to Seaville.
+</p>
+
+<p>
+“Why—er, yes,” he said frankly, raising his eyes and looking at Craig in
+surprise. “There have been a dozen or more such substances. The best is one
+which I use, made of pyroxylin, the soluble cotton of commerce, dissolved in
+amyl acetate and acetone with some other substances that make it perfectly
+sterile. Why do you ask?”
+</p>
+
+<p>
+“Because some one has used a little bit of it to cover a few slight cuts on the
+back of the neck of Mrs. Edwards.”
+</p>
+
+<p>
+“Indeed?” he said simply, in a tone of mild surprise.
+</p>
+
+<p>
+“Yes,” pursued Kennedy. “They seem to me to be subcutaneous incisions of the
+neck with a very fine scalpel dividing the two great pneumogastric nerves. Of
+course you know what that would mean—the victim would pass away naturally by
+slow and easy stages in three or four days, and all that would appear might be
+congestion of the lungs. They are delicate little punctures and elusive nerves
+to locate, but after all it might be done as painlessly, as simply and as
+safely as a barber might remove some dead hairs. A country coroner might easily
+pass over such evidence at an autopsy—especially if it was concealed by skin
+varnish.”
+</p>
+
+<p>
+I was surprised at the frankness with which Kennedy spoke, but absolutely
+amazed at the coolness of Jermyn. At first he said absolutely nothing. He
+seemed to be as set in his reticence as he had been when we first met.
+</p>
+
+<p>
+I watched him narrowly. Waldon, who was driving the boat, had not heard what
+was said, but I had, and I could not conceive how anyone could take it so
+calmly.
+</p>
+
+<p>
+Finally Jermyn turned to Kennedy and looked him squarely in the eye. “Kennedy,”
+he said slowly, “this is extraordinary—most extraordinary,” then, pausing,
+added, “if true.”
+</p>
+
+<p>
+“There can be no doubt of the truth,” replied Kennedy, eyeing Dr. Jermyn just
+as squarely.
+</p>
+
+<p>
+“What do you propose to do about it?” asked the doctor.
+</p>
+
+<p>
+“Investigate,” replied Kennedy simply. “While Waldon takes these things up to
+the undertaker’s, we may as well wait here in the boat. I want him to stop on
+the way back for Mr. Edwards. Then we shall go out to the <i>Lucie</i>. He must
+go, whether he likes it or not.”
+</p>
+
+<p>
+It was indeed a most peculiar situation as Kennedy and I sat in the tender with
+Dr. Jermyn waiting for Waldon to return with Edwards. Not a word was spoken.
+</p>
+
+<p>
+The tenseness of the situation was not relieved by the return of Waldon with
+Edwards. Waldon seemed to realize without knowing just what it was, that
+something was about to happen. He drove his boat back to the <i>Lucie</i> again
+in record time. This was Kennedy’s turn to be reticent. Whatever it was he was
+revolving in his mind, he answered in scarcely more than monosyllables whatever
+questions were put to him.
+</p>
+
+<p>
+“You are not coming aboard?” inquired Edwards in surprise as he and Jermyn
+mounted the steps of the houseboat ladder, and Kennedy remained seated in the
+tender.
+</p>
+
+<p>
+“Not yet,” replied Craig coolly.
+</p>
+
+<p>
+“But I thought you had something to show me. Waldon told me you had.”
+</p>
+
+<p>
+“I think I shall have in a short time,” returned Kennedy. “We shall be back
+immediately. I’m just going to ask Waldon to run over to the <i>Nautilus</i>
+for a few minutes. We’ll tow back your launch, too, in case you need it.”
+</p>
+
+<p>
+Waldon had cast off obediently.
+</p>
+
+<p>
+“There’s one thing sure,” I remarked. “Jermyn can’t get away from the
+<i>Lucie</i> until we return—unless he swims.”
+</p>
+
+<p>
+Kennedy did not seem to pay much attention to the remark, for his only reply
+was: “I’m taking a chance by this maneuvering, but I think it will work out
+that I am correct. By the way, Waldon, you needn’t put on so much speed. I’m in
+no great hurry to get back. Half an hour will be time enough.”
+</p>
+
+<p>
+“Jermyn? What did you mean by Jermyn?” asked Waldon, as we climbed to the deck
+of the <i>Nautilus</i>.
+</p>
+
+<p>
+He had evidently learned, as I had, that it was little use to try to quiz
+Kennedy until he was ready to be questioned and had decided to try it on me.
+</p>
+
+<p>
+I had nothing to conceal and I told him quite fully all that I knew. Actually,
+I believe if Jermyn had been there, it would have taken both Kennedy and myself
+to prevent violence. As it was I had a veritable madman to deal with while
+Kennedy gathered up leisurely the wireless outfit he had installed on the deck
+of Waldon’s yacht. It was only by telling him that I would certainly demand
+that Kennedy leave him behind if he did not control his feelings that I could
+calm him before Craig had finished his work on the yacht.
+</p>
+
+<p>
+Waldon relieved himself by driving the tender back at top speed to the
+<i>Lucie</i>, and now it seemed that Kennedy had no objection to traveling as
+fast as the many-cylindered engine was capable of going.
+</p>
+
+<p>
+As we entered the saloon of the houseboat, I kept close watch over Waldon.
+</p>
+
+<p>
+Kennedy began by slipping a record on the phonograph in the corner of the
+saloon, then facing us and addressing Edwards particularly.
+</p>
+
+<p>
+“You may be interested to know, Mr. Edwards,” he said, “that your wireless
+outfit here has been put to a use for which you never intended it.”
+</p>
+
+<p>
+No one said anything, but I am sure that some one in the room then for the
+first time began to suspect what was coming.
+</p>
+
+<p>
+“As you know, by the use of an aërial pole, messages may be easily received
+from any number of stations,” continued Craig. “Laws, rules and regulations may
+be adopted to shut out interlopers and plug busybody ears, but the greater part
+of whatever is transmitted by the Hertzian waves can be snatched down by other
+wireless apparatus.
+</p>
+
+<p>
+“Down below, in that little room of yours,” went on Craig, “might sit an
+operator with his ear-phone clamped to his head, drinking in the news conveyed
+surely and swiftly to him through the wireless signals—plucking from the sky
+secrets of finance and,” he added, leaning forward, “love.”
+</p>
+
+<p>
+In his usual dramatic manner Kennedy had swung his little audience completely
+with him.
+</p>
+
+<p>
+“In other words,” he resumed, “it might be used for eavesdropping by a wireless
+wiretapper. Now,” he concluded, “I thought that if there was any radio
+detective work being done, I might as well do some, too.”
+</p>
+
+<p>
+He toyed for a moment with the phonograph record. “I have used,” he explained,
+“Marconi’s radiotelephone, because in connection with his receivers Marconi
+uses phonographic recorders and on them has captured wireless telegraph signals
+over hundreds of miles.
+</p>
+
+<p>
+“He has found that it is possible to receive wireless signals, although
+ordinary records are not loud enough, by using a small microphone on the
+repeating diaphragm and connected with a loud-speaking telephone. The chief
+difficulty was to get a microphone that would carry a sufficient current
+without burning up. There were other difficulties, but they have been
+surmounted and now wireless telegraph messages may be automatically recorded
+and made audible.”
+</p>
+
+<p>
+Kennedy started the phonograph, running it along, stopping it, taking up the
+record at a new point.
+</p>
+
+<p>
+“Listen,” he exclaimed at length, “there’s something interesting, the WXY
+call—Seaville station—from some one on the <i>Lucie</i> only a few minutes ago,
+sending a message to be relayed by Seaville to the station at Beach Park. It
+seems impossible, but buzzing and ticking forth is this message from some one
+off this very houseboat. It reads: “Miss Valerie Fox, Beach Park. I am
+suspected of the murder of Mrs. Edwards. I appeal to you to help me. You must
+allow me to tell the truth about the messages I intercepted for Mrs. Edwards
+which passed between yourself on the ocean and Mr. Edwards in New York via
+Seaville. You rejected me and would not let me save you. Now you must save me.”
+</p>
+
+<p>
+Kennedy paused, then added, “The message is signed by Dr. Jermyn!”
+</p>
+
+<p>
+At once I saw it all. Jermyn had been the unsuccessful suitor for Miss Fox’s
+affections. But before I could piece out the rest of the tragic story, Kennedy
+had started the phonograph record at an earlier point which he had skipped for
+the present.
+</p>
+
+<p>
+“Here’s another record—a brief one—also to Valerie Fox from the houseboat:
+‘Refuse all interviews. Deny everything. Will see you as soon as present
+excitement dies down.’”
+</p>
+
+<p>
+Before Kennedy could finish, Waldon had leaped forward, unable longer to
+control his feelings. If Kennedy had not seized his arm, I verily believe he
+would have cast Dr. Jermyn into the bay into which his sister had fallen two
+nights before in her terribly weakened condition.
+</p>
+
+<p>
+“Waldon,” cried Kennedy, “for God’s sake, man—wait! Don’t you understand? The
+second message is signed Tracy Edwards.”
+</p>
+
+<p>
+It came as quite as much a shock of surprise to me as to Waldon.
+</p>
+
+<p>
+“Don’t you understand?” he repeated. “Your sister first learned from Dr. Jermyn
+what was going on. She moved the <i>Lucie</i> down here near Seaville in order
+to be near the wireless station when the ship bearing her rival, Valerie Fox,
+got in touch with land. With the help of Dr. Jermyn she intercepted the
+wireless messages from the <i>Kronprinz</i> to the shore—between her husband
+and Valerie Fox.”
+</p>
+
+<p>
+Kennedy was hurrying on now to his irresistible conclusion. “She found that he
+was infatuated with the famous stage beauty, that he was planning to marry
+another, her rival. She accused him of it, threatened to defeat his plans. He
+knew she knew his unfaithfulness. Instead of being your sister’s murderer, Dr.
+Jermyn was helping her get the evidence that would save both her and perhaps
+win Miss Fox back to himself.”
+</p>
+
+<p>
+Kennedy had turned sharply on Edwards.
+</p>
+
+<p>
+“But,” he added, with a glance that crushed any lingering hope that the truth
+had been concealed, “the same night that Dr. Jermyn arrived here, you visited
+your wife. As she slept you severed the nerves that meant life or death to her.
+Then you covered the cuts with the preparation which you knew Dr. Jermyn used.
+You asked him to stay, while you went away, thinking that when death came you
+would have a perfect alibi—perhaps a scapegoat. Edwards, the radio detective
+convicts you!”

+THE CURIO SHOP</h2>
+
+<p>
+Edwards crumpled up as Kennedy and I faced him. There was no escape. In fact
+our greatest difficulty was to protect him from Waldon.
+</p>
+
+<p>
+Kennedy’s work in the case was over when we had got Edwards ashore and in the
+hands of the authorities. But mine had just begun and it was late when I got my
+story on the wire for the <i>Star</i>.
+</p>
+
+<p>
+I felt pretty tired and determined to make up for it by sleeping the next day.
+It was no use, however.
+</p>
+
+<p>
+“Why, what’s the matter, Mrs. Northrop?” I heard Kennedy ask as he opened our
+door the next morning, just as I had finished dressing.
+</p>
+
+<p>
+He had admitted a young woman, who greeted us with nervous, wide-staring eyes.
+</p>
+
+<p>
+“It’s—it’s about Archer,” she cried, sinking into the nearest chair and staring
+from one to the other of us.
+</p>
+
+<p>
+She was the wife of Professor Archer Northrop, director of the archeological
+department at the university. Both Craig and I had known her ever since her
+marriage to Northrop, for she was one of the most attractive ladies in the
+younger set of the faculty, to which Craig naturally belonged. Archer had been
+of the class below us in the university. We had hazed him, and out of the mild
+hazing there had, strangely enough, grown a strong friendship.
+</p>
+
+<p>
+I recollected quickly that Northrop, according to last reports, had been down
+in the south of Mexico on an archeological expedition. But before I could
+frame, even in my mind, the natural question in a form that would not alarm his
+wife further, Kennedy had it on his lips.
+</p>
+
+<p>
+“No bad news from Mitla, I hope?” he asked gently, recalling one of the main
+working stations chosen by the expedition and the reported unsettled condition
+of the country about it. She looked up quickly.
+</p>
+
+<p>
+“Didn’t you know—he—came back from Vera Cruz yesterday?” she asked slowly, then
+added, speaking in a broken tone, “and—he seems—suddenly—to have disappeared.
+Oh, such a terrible night of worry! No word—and I called up the museum, but
+Doctor Bernardo, the curator, had gone, and no one answered. And this morning—I
+couldn’t stand it any longer—so I came to you.”
+</p>
+
+<p>
+“You have no idea, I suppose, of anything that was weighing on his mind?”
+suggested Kennedy.
+</p>
+
+<p>
+“No,” she answered promptly.
+</p>
+
+<p>
+In default of any further information, Kennedy did not pursue this line of
+questioning. I could not determine from his face or manner whether he thought
+the matter might involve another than Mrs. Northrop, or, perhaps, something
+connected with the unsettled condition of the country from which her husband
+had just arrived.
+</p>
+
+<p>
+“Have you any of the letters that Archer wrote home?” asked Craig, at length.
+</p>
+
+<p>
+“Yes,” she replied eagerly, taking a little packet from her handbag. “I thought
+you might ask that. I brought them.”
+</p>
+
+<p>
+“You are an ideal client,” commented Craig encouragingly, taking the letters.
+“Now, Mrs. Northrop, be brave. Trust me to run this thing down, and if you hear
+anything let me know immediately.”
+</p>
+
+<p>
+She left us a moment later, visibly relieved.
+</p>
+
+<p>
+Scarcely had she gone when Craig, stuffing the letters into his pocket unread,
+seized his hat, and a moment later was striding along toward the museum with
+his habitual rapid, abstracted step which told me that he sensed a mystery.
+</p>
+
+<p>
+In the museum we met Doctor Bernardo, a man slightly older than Northrop, with
+whom he had been very intimate. He had just arrived and was already deeply
+immersed in the study of some new and beautiful colored plates from the
+National Museum of Mexico City.
+</p>
+
+<p>
+“Do you remember seeing Northrop here yesterday afternoon?” greeted Craig,
+without explaining what had happened.
+</p>
+
+<p>
+“Yes,” he answered promptly. “I was here with him until very late. At least, he
+was in his own room, working hard, when I left.”
+</p>
+
+<p>
+“Did you see him go?”
+</p>
+
+<p>
+“Why—er—no,” replied Bernardo, as if that were a new idea. “I left him here—at
+least, I didn’t see him go out.”
+</p>
+
+<p>
+Kennedy tried the door of Northrop’s room, which was at the far end, in a
+corner, and communicated with the hall only through the main floor of the
+museum. It was locked. A pass-key from the janitor quickly opened it.
+</p>
+
+<p>
+Such a sight as greeted us, I shall never forget. There, in his big desk-chair,
+sat Northrop, absolutely rigid, the most horribly contorted look on his
+features that I have ever seen—half of pain, half of fear, as if of something
+nameless.
+</p>
+
+<p>
+Kennedy bent over. His hands were cold.
+</p>
+
+<p>
+Northrop had been dead at least twelve hours, perhaps longer. All night the
+deserted museum had guarded its terrible secret.
+</p>
+
+<p>
+As Craig peered into his face, he saw, in the fleshy part of the neck, just
+below the left ear, a round red mark, with just a drop or two of now black
+coagulated blood in the center. All around we could see a vast amount of
+miscellaneous stuff, partly unpacked, partly just opened, and waiting to be
+taken out of the wrappings by the now motionless hands.
+</p>
+
+<p>
+“I suppose you are more or less familiar with what Northrop brought back?”
+asked Kennedy of Bernardo, running his eye over the material in the room.
+</p>
+
+<p>
+“Yes, reasonably,” answered Bernardo. “Before the cases arrived from the wharf,
+he told me in detail what he had managed to bring up with him.”
+</p>
+
+<p>
+“I wish, then, that you would look it over and see if there is anything
+missing,” requested Craig, already himself busy in going over the room for
+other evidence.
+</p>
+
+<p>
+Doctor Bernardo hastily began taking a mental inventory of the stuff. While
+they worked, I tried vainly to frame some theory which would explain the
+startling facts we had so suddenly discovered.
+</p>
+
+<p>
+Mitla, I knew, was south of the city of Oaxaca, and there, in its ruined
+palaces, was the crowning achievement of the old Zapotec kings. No ruins in
+America were more elaborately ornamented or richer in lore for the
+archeologist.
+</p>
+
+<p>
+Northrop had brought up porphyry blocks with quaint grecques and much
+hieroglyphic painting. Already unpacked were half a dozen copper axes, some of
+the first of that particular style that had ever been brought to the United
+States. Besides the sculptured stones and the mosaics were jugs, cups, vases,
+little gods, sacrificial stones—enough, almost, to equip a new alcove in the
+museum.
+</p>
+
+<p>
+Before Northrop was an idol, a hideous thing on which frogs and snakes squatted
+and coiled. It was a fitting piece to accompany the gruesome occupant of the
+little room in his long, last vigil. In fact, it almost sent a shudder over me,
+and if I had been inclined to the superstitious, I should certainly have
+concluded that this was retribution for having disturbed the <i>lares</i> and
+<i>penates</i> of a dead race.
+</p>
+
+<p>
+Doctor Bernardo was going over the material a second time. By the look on his
+face, even I could guess that something was missing.
+</p>
+
+<p>
+“What is it?” asked Craig, following the curator closely.
+</p>
+
+<p>
+“Why,” he answered slowly, “there was an inscription—we were looking at it
+earlier in the day—on a small block of porphyry. I don’t see it.”
+</p>
+
+<p>
+He paused and went back to his search before we could ask him further what he
+thought the inscription was about.
+</p>
+
+<p>
+I thought nothing myself at the time of his reticence, for Kennedy had gone
+over to a window back of Northrop and to the left. It was fully twenty feet
+from the downward slope of the campus there, and, as he craned his neck out, he
+noted that the copper leader of the rain pipe ran past it a few feet away.
+</p>
+
+<p>
+I, too, looked out. A thick group of trees hid the window from the avenue
+beyond the campus wall, and below us, at a corner of the building, was a clump
+of rhododendrons. As Craig bent over the sill, he whipped out a pocket lens.
+</p>
+
+<p>
+A moment later he silently handed the glass to me. As nearly as I could make
+out, there were five marks on the dust of the sill.
+</p>
+
+<p>
+“Finger-prints!” I exclaimed. “Some one has been clinging to the edge of the
+ledge.”
+</p>
+
+<p>
+“In that case,” Craig observed quietly, “there would have been only four
+prints.”
+</p>
+
+<p>
+I looked again, puzzled. The prints were flat and well separated.
+</p>
+
+<p>
+“No,” he added, “not finger-prints—toe-prints.”
+</p>
+
+<p>
+“Toe-prints?” I echoed.
+</p>
+
+<p>
+Before he could reply, Craig had dashed out of the room, around, and under the
+window. There, he was carefully going over the soft earth around the bushes
+below.
+</p>
+
+<p>
+“What are you looking for?” I asked, joining him.
+</p>
+
+<p>
+“Some one—perhaps two—has been here,” he remarked, almost under his breath.
+“One, at least, has removed his shoes. See those shoe-prints up to this point?
+The print of a boot-heel in soft earth shows the position and contour of every
+nail head. Bertillon has made a collection of such nails, certain types, sizes,
+and shapes used in certain boots, showing often what country the shoes came
+from. Even the number and pattern are significant. Some factories use a fixed
+number of nails and arrange them in a particular manner. I have made my own
+collection of such prints in this country. These were American shoes. Perhaps
+the clue will not lead us anywhere, though, for I doubt whether it was an
+American foot.”
+</p>
+
+<p>
+Kennedy continued to study the marks.
+</p>
+
+<p>
+“He removed his shoes—either to help in climbing or to prevent noise—ah—here’s
+the foot! Strange—see how small it is—and broad, how prehensile the toes—almost
+like fingers. Surely that foot could never have been encased in American shoes
+all its life. I shall make plaster casts of these, to preserve later.”
+</p>
+
+<p>
+He was still scouting about on hands and knees in the dampness of the
+rhododendrons. Suddenly he reached his long arm in among the shrubs and picked
+up a little reed stick. On the end of it was a small cylinder of buff brown.
+</p>
+
+<p>
+He looked at it curiously, dug his nail into the soft mass, then rubbed his
+nail over the tip of his tongue gingerly.
+</p>
+
+<p>
+With a wry face, as if the taste were extremely acrid, he moistened his
+handkerchief and wiped off his tongue vigorously.
+</p>
+
+<p>
+“Even that minute particle that was on my nail makes my tongue tingle and feel
+numb,” he remarked, still rubbing. “Let us go back again. I want to see
+Bernardo.”
+</p>
+
+<p>
+“Had he any visitors during the day?” queried Kennedy, as he reentered the
+ghastly little room, while the curator stood outside, completely unnerved by
+the tragedy which had been so close to him without his apparently knowing it.
+Kennedy was squeezing out from the little wound on Northrop’s neck a few drops
+of liquid on a sterilized piece of glass.
+</p>
+
+<p>
+“No; no one,” Bernardo answered, after a moment.
+</p>
+
+<p>
+“Did you see anyone in the museum who looked suspicious?” asked Kennedy,
+watching Bernardo’s face keenly.
+</p>
+
+<p>
+“No,” he hesitated. “There were several people wandering about among the
+exhibits, of course. One, I recall, late in the afternoon, was a little
+dark-skinned woman, rather good-looking.”
+</p>
+
+<p>
+“A Mexican?”
+</p>
+
+<p>
+“Yes, I should say so. Not of Spanish descent, though. She was rather of the
+Indian type. She seemed to be much interested in the various exhibits, asked me
+several questions, very intelligently, too. Really, I thought she was trying
+to—er—flirt with me.”
+</p>
+
+<p>
+He shot a glance at Craig, half of confession, half of embarrassment.
+</p>
+
+<p>
+“And—oh, yes—there was another—a man, a little man, as I recall, with shaggy
+hair. He looked like a Russian to me. I remember, because he came to the door,
+peered around hastily, and went away. I thought he might have got into the
+wrong part of the building and went to direct him right—but before I could get
+out into the hall, he was gone. I remember, too, that, as I turned, the woman
+had followed me and soon was asking other questions—which, I will admit—I was
+glad to answer.”
+</p>
+
+<p>
+“Was Northrop in his room while these people were here?”
+</p>
+
+<p>
+“Yes; he had locked the door so that none of the students or visitors could
+disturb him.”
+</p>
+
+<p>
+“Evidently the woman was diverting your attention while the man entered
+Northrop’s room by the window,” ruminated Craig, as we stood for a moment in
+the outside doorway.
+</p>
+
+<p>
+He had already telephoned to our old friend Doctor Leslie, the coroner, to take
+charge of the case, and now was ready to leave. The news had spread, and the
+janitor of the building was waiting to lock the campus door to keep back the
+crowd of students and others.
+</p>
+
+<p>
+Our next duty was the painful one of breaking the news to Mrs. Northrop. I
+shall pass it over. Perhaps no one could have done it more gently than Kennedy.
+She did not cry. She was simply dazed. Fortunately her mother was with her, had
+been, in fact, ever since Northrop had gone on the expedition.
+</p>
+
+<p>
+“Why should anyone want to steal tablets of old Mixtec inscriptions?” I asked
+thoughtfully, as we walked sadly over the campus in the direction of the
+chemistry building. “Have they a sufficient value, even on appreciative Fifth
+Avenue, to warrant murder?”
+</p>
+
+<p>
+“Well,” he remarked, “it does seem incomprehensible. Yet people do just such
+things. The psychologists tell us that there is a veritable mania for
+possessing such curios. However, it is possible that there may be some deeper
+significance in this case,” he added, his face puckered in thought.
+</p>
+
+<p>
+Who was the mysterious Mexican woman, who the shaggy Russian? I asked myself.
+Clearly, at least, if she existed at all, she was one of the millions not of
+Spanish but of Indian descent in the country south of us. As I reasoned it out,
+it seemed to me as if she must have been an accomplice. She could not have got
+into Northrop’s room either before or after Doctor Bernardo left. Then, too,
+the toe-and shoe-prints were not hers. But, I figured, she certainly had a part
+in the plot.
+</p>
+
+<p>
+While I was engaged in the vain effort to unravel the tragic affair by pure
+reason, Kennedy was at work with practical science.
+</p>
+
+<p>
+He began by examining the little dark cylinder on the end of the reed. On a
+piece of the stuff, broken off, he poured a dark liquid from a brown-glass
+bottle. Then he placed it under a microscope.
+</p>
+
+<p>
+“Microscopically,” he said slowly, “it consists almost wholly of minute, clear
+granules which give a blue reaction with iodine. They are starch. Mixed with
+them are some larger starch granules, a few plant cells, fibrous matter, and
+other foreign particles. And then, there is the substance that gives that
+acrid, numbing taste.” He appeared to be vacantly studying the floor.
+</p>
+
+<p>
+“What do you think it is?” I asked, unable to restrain myself.
+</p>
+
+<p>
+“Aconite,” he answered slowly, “of which the active principle is the deadly
+poisonous alkaloid, aconitin.”
+</p>
+
+<p>
+He walked over and pulled down a well-thumbed standard work on toxicology,
+turned the pages, then began to read aloud:
+</p>
+
+<p class="p2">
+Pure aconitin is probably the most actively poisonous substance with which we
+are acquainted and, if administered hypodermically, the alkaloid is even more
+powerfully poisonous than when taken by the mouth.
+</p>
+
+<p>
+As in the case of most of the poisonous alkaloids, aconitin does not produce
+any decidedly characteristic post-mortem appearances. There is no way to
+distinguish it from other alkaloids, in fact, no reliable chemical test. The
+physiological effects before death are all that can be relied on.
+</p>
+
+<p>
+Owing to its exceeding toxic nature, the smallness of the dose required to
+produce death, and the lack of tests for recognition, aconitin possesses rather
+more interest in legal medicine than most other poisons.
+</p>
+
+<p>
+It is one of the few substances which, in the present state of toxicology,
+might be criminally administered and leave no positive evidence of the crime.
+If a small but fatal dose of the poison were to be given, especially if it were
+administered hypodermically, the chances of its detection in the body after
+death would be practically none.

+THE “PILLAR OF DEATH”</h2>
+
+<p>
+I was looking at him fixedly as the diabolical nature of what must have
+happened sank into my mind. Here was a poison that defied detection. I could
+see by the look on Craig’s face that that problem, alone, was enough to absorb
+his attention. He seemed fully to realize that we had to deal with a criminal
+so clever that he might never be brought to justice.
+</p>
+
+<p>
+An idea flashed over me.
+</p>
+
+<p>
+“How about the letters?” I suggested.
+</p>
+
+<p>
+“Good, Walter!” he exclaimed.
+</p>
+
+<p>
+He untied the package which Mrs. Northrop had given him and glanced quickly
+over one after another of the letters.
+</p>
+
+<p>
+“Ah!” he exclaimed, fairly devouring one dated at Mitla. “Listen—it tells about
+Northrop’s work and goes on:
+</p>
+
+<p class="p2">
+“‘I have been much interested in a cavern, or <i>subterraneo</i>, here, in the
+shape of a cross, each arm of which extends for some twelve feet underground.
+In the center it is guarded by a block of stone popularly called “the Pillar of
+Death.” There is a superstition that whoever embraces it will die before the
+sun goes down.
+</p>
+
+<p>
+“‘From the <i>subterraneo</i> is said to lead a long, underground passage
+across the court to another subterranean chamber which is full of Mixtec
+treasure. Treasure hunters have dug all around it, and it is said that two old
+Indians, only, know of the immense amount of buried gold and silver, but that
+they will not reveal it.’”
+</p>
+
+<p>
+I started up. Here was the missing link which I had been waiting for.
+</p>
+
+<p>
+“There, at least, is the motive,” I blurted out. “That is why Bernardo was so
+reticent. Northrop, in his innocence of heart, had showed him that
+inscription.”
+</p>
+
+<p>
+Kennedy said nothing as he finally tied up the little packet of letters and
+locked it in his safe. He was not given to hasty generalizations; neither was
+he one who clung doggedly to a preconceived theory.
+</p>
+
+<p>
+It was still early in the afternoon. Craig and I decided to drop into the
+museum again in order to see Doctor Bernardo. He was not there and we sat down
+to wait.
+</p>
+
+<p>
+Just then the letter box in the door clicked. It was the postman on his rounds.
+Kennedy walked over and picked up the letter.
+</p>
+
+<p>
+The postmark bore the words, “Mexico City,” and a date somewhat later than that
+on which Northrop had left Vera Cruz. In the lower corner, underscored, were
+the words, “Personal—Urgent.”
+</p>
+
+<p>
+“I’d like to know what is in that,” remarked Craig, turning it over and over.
+</p>
+
+<p>
+He appeared to be considering something, for he rose suddenly and shoved the
+letter into his pocket.
+</p>
+
+<p>
+I followed, and a few moments later, across the campus in his laboratory, he
+was working quickly over an X-ray apparatus. He had placed the letter in it.
+</p>
+
+<p>
+“These are what are known as ‘low’ tubes,” he explained. “They give out ‘soft
+rays.’” He continued to work for a few moments, then handed me the letter.
+</p>
+
+<p>
+“Now, Walter,” he said, “if you will just hurry back to the museum and replace
+that letter, I think I will have something that will astonish you—though
+whether it will have any bearing on the case, remains to be seen.”
+</p>
+
+<p>
+“What is it?” I asked, a few minutes later, when I had rejoined him, after
+returning the letter. He was poring intently over what looked like a negative.
+</p>
+
+<p>
+“The possibility of reading the contents of documents inclosed in a sealed
+envelope,” he replied, still studying the shadowgraph closely, “has already
+been established by the well-known English scientist, Doctor Hall Edwards. He
+has been experimenting with the method of using X-rays recently discovered by a
+German scientist, by which radiographs of very thin substances, such as a sheet
+of paper, a leaf, an insect’s body, may be obtained. These thin substances
+through which the rays used formerly to pass without leaving an impression, can
+now be radiographed.”
+</p>
+
+<p>
+I looked carefully as he traced out something on the negative. On it was easily
+possible, following his guidance, to read the words inscribed on the sheet of
+paper inside. So admirably defined were all the details that even the gum on
+the envelope and the edges of the sheet of paper inside the envelope could be
+distinguished.
+</p>
+
+<p>
+“Any letter written with ink having a mineral basis can be radiographed,” added
+Craig. “Even when the sheet is folded in the usual way, it is possible by
+taking a radiograph stereoscopically, to distinguish the writing, every detail
+standing out in relief. Besides, it can be greatly magnified, which aids in
+deciphering it if it is indistinct or jumbled up. Some of it looks like mirror
+writing. Ah,” he added, “here’s something interesting!”
+</p>
+
+<p>
+Together we managed to trace out the contents of several paragraphs, of which
+the significant parts were as follows:
+</p>
+
+<p class="p2">
+I am expecting that my friend Señora Herreria will be in New York by the time
+you receive this, and should she call on you, I know you will accord her every
+courtesy. She has been in Mexico City for a few days, having just returned from
+Mitla, where she met Professor Northrop. It is rumored that Professor Northrop
+has succeeded in smuggling out of the country a very important stone bearing an
+inscription which, I understand, is of more than ordinary interest. I do not
+know anything definite about it, as Señora Herreria is very reticent on the
+matter, but depend on you to find out if possible and let me know of it.
+</p>
+
+<p>
+According to the rumors and the statements of the <i>señora</i>, it seems that
+Northrop has taken an unfair advantage of the situation down in Oaxaca, and I
+suppose she and others who know about the inscription feel that it is really
+the possession of the government.
+</p>
+
+<p>
+You will find that the <i>señora</i> is an accomplished antiquarian and
+scholar. Like many others down here just now, she has a high regard for the
+Japanese. As you know, there exists a natural sympathy between some Mexicans
+and Japanese, owing to what is believed to be a common origin of the two races.
+</p>
+
+<p>
+In spite of the assertions of many to the contrary, there is little doubt left
+in the minds of students that the Indian races which have peopled Mexico were
+of Mongolian stock. Many words in some dialects are easily understood by
+Chinese immigrants. A secretary of the Japanese legation here was able recently
+to decipher old Mixtec inscriptions found in the ruins of Mitla.
+</p>
+
+<p>
+Señora Herreria has been much interested in establishing the relationship and,
+I understand, is acquainted with a Japanese curio dealer in New York who
+recently visited Mexico for the same purpose. I believe that she wishes to
+collaborate with him on a monograph on the subject, which is expected to have a
+powerful effect on the public opinion both here and at Tokyo.
+</p>
+
+<p>
+In regard to the inscription which Northrop has taken with him, I rely on you
+to keep me informed. There seems to be a great deal of mystery connected with
+it, and I am simply hazarding a guess as to its nature. If it should prove to
+be something which might interest either the Japanese or ourselves, you can see
+how important it may be, especially in view of the forthcoming mission of
+General Francisco to Tokyo.
+</p>
+
+<p class="right">
+Very sincerely yours,<br/>
+D<small>R</small>. E<small>MILIO</small> S<small>ANCHEZ</small>, Director.
+</p>
+
+<p>
+“Bernardo is a Mexican,” I exclaimed, as Kennedy finished reading, “and there
+can be no doubt that the woman he mentioned was this Señora Herreria.”
+</p>
+
+<p>
+Kennedy said nothing, but seemed to be weighing the various paragraphs in the
+letter.
+</p>
+
+<p>
+“Still,” I observed, “so far, the only one against whom we have any direct
+suspicion in the case is the shaggy Russian, whoever he is.”
+</p>
+
+<p>
+“A man whom Bernardo says looked like a Russian,” corrected Craig.
+</p>
+
+<p>
+He was pacing the laboratory restlessly.
+</p>
+
+<p>
+“This is becoming quite an international affair,” he remarked finally, pausing
+before me, his hat on. “Would you like to relax your mind by a little excursion
+among the curio shops of the city? I know something about Japanese curios—more,
+perhaps, than I do of Mexican. It may amuse us, even if it doesn’t help in
+solving the mystery. Meanwhile, I shall make arrangements for shadowing
+Bernardo. I want to know just how he acts after he reads that letter.”
+</p>
+
+<p>
+He paused long enough to telephone his instructions to an uptown detective
+agency which could be depended on for such mere routine work, then joined me
+with the significant remark: “Blood is thicker than water, anyhow, Walter.
+Still, even if the Mexicans are influenced by sentiment, I hardly think that
+would account for the interest of our friends from across the water in the
+matter.”
+</p>
+
+<p>
+I do not know how many of the large and small curio shops of the city we
+visited that afternoon. At another time, I should have enjoyed the visits
+immensely, for anyone seeking articles of beauty will find the antique shops of
+Fifth and Fourth Avenues and the side streets well worth visiting.
+</p>
+
+<p>
+We came, at length, to one, a small, quaint, dusty rookery, down in a basement,
+entered almost directly from the street. It bore over the door a little gilt
+sign which read simply, “Sato’s.”
+</p>
+
+<p>
+As we entered, I could not help being impressed by the wealth of articles in
+beautiful cloisonne enamel, in mother-of-pearl, lacquer, and champleve. There
+were beautiful little koros, or incense burners, vases, and teapots. There were
+enamels incrusted, translucent, and painted, works of the famous Namikawa, of
+Kyoto, and Namikawa, of Tokyo. Satsuma vases, splendid and rare examples of the
+potter’s art, crowded gorgeously embroidered screens depicting all sorts of
+brilliant scenes, among others the sacred Fujiyama rising in the stately
+distance. Sato himself greeted us with a ready smile and bow.
+</p>
+
+<p>
+“I am just looking for a few things to add to my den,” explained Kennedy,
+adding, “nothing in particular, but merely whatever happens to strike my
+fancy.”
+</p>
+
+<p>
+“Surely, then, you have come to the right shop,” greeted Sato. “If there is
+anything that interests you, I shall be glad to show it.”
+</p>
+
+<p>
+“Thank you,” replied Craig. “Don’t let me trouble you with your other
+customers. I will call on you if I see anything.”
+</p>
+
+<p>
+For several minutes, Craig and I busied ourselves looking about, and we did not
+have to feign interest, either.
+</p>
+
+<p>
+“Often things are not as represented,” he whispered to me, after a while, “but
+a connoiseur can tell spurious goods. These are the real thing, mostly.”
+</p>
+
+<p>
+“Not one in fifty can tell the difference,” put in the voice of Sato, at his
+elbow.
+</p>
+
+<p>
+“Well, you see I happen to know,” Craig replied, not the least disconcerted.
+“You can’t always be too sure.”
+</p>
+
+<p>
+A laugh and a shrug was Sato’s answer. “It’s well all are not so keen,” he
+said, with a frank acknowledgment that he was not above sharp practices.
+</p>
+
+<p>
+I glanced now and then at the expressionless face of the curio dealer. Was it
+merely the natural blankness of his countenance that impressed me, or was
+there, in fact, something deep and dark hidden in it, something of “East is
+East and West is West” which I did not and could not understand? Craig was
+admiring the bronzes. He had paused before one, a square metal fire-screen of
+odd design, with the title on a card, “Japan Gazing at the World.”
+</p>
+
+<p>
+It represented Japan as an eagle, with beak and talons of burnished gold,
+resting on a rocky island about which great waves dashed. The bird had an air
+of dignity and conscious pride in its strength, as it looked out at the world,
+a globe revolving in space.
+</p>
+
+<p>
+“Do you suppose there is anything significant in that?” I asked, pointing to
+the continent of North America, also in gold and prominently in view.
+</p>
+
+<p>
+“Ah, honorable sir,” answered Sato, before Kennedy could reply, “the artist
+intended by that to indicate Japan’s friendliness for America and America’s
+greatness.”
+</p>
+
+<p>
+He was inscrutable. It seemed as if he were watching our every move, and yet it
+was done with a polite cordiality that could not give offense.
+</p>
+
+<p>
+Behind some bronzes of the Japanese Hercules destroying the demons and other
+mythical heroes was a large alcove, or <i>tokonoma</i>, decorated with peacock,
+stork, and crane panels. Carvings and lacquer added to the beauty of it. A
+miniature chrysanthemum garden heightened the illusion. Carved <i>hinoki</i>
+wood framed the panels, and the roof was supported by columns in the old
+Japanese style, the whole being a compromise between the very simple and quiet
+and the polychromatic. The dark woods, the lanterns, the floor tiles of dark
+red, and the cushions of rich gold and yellow were most alluring. It had the
+genuine fascination of the Orient.
+</p>
+
+<p>
+“Will the gentlemen drink a little <i>sake?</i>” Sato asked politely.
+</p>
+
+<p>
+Craig thanked him and said that we would.
+</p>
+
+<p>
+“Otaka!” Sato called.
+</p>
+
+<p>
+A peculiar, almost white-skinned attendant answered, and a moment later
+produced four cups and poured out the rice brandy, taking his own quietly,
+apart from us. I watched him drink, curiously. He took the cup; then, with a
+long piece of carved wood, he dipped into the <i>sake</i>, shaking a few drops
+on the floor to the four quarters. Finally, with a deft sweep, he lifted his
+heavy mustache with the piece of wood and drank off the draft almost without
+taking breath.
+</p>
+
+<p>
+He was a peculiar man of middle height, with a shock of dark, tough, woolly
+hair, well formed and not bad-looking, with a robust general physique, as if
+his ancestors had been meat eaters. His forehead was narrow and sloped
+backward; the cheekbones were prominent; nose hooked, broad and wide, with
+strong nostrils; mouth large, with thick lips, and not very prominent chin. His
+eyes were perhaps the most noticeable feature. They were dark gray, almost like
+those of a European.
+</p>
+
+<p>
+As Otaka withdrew with the empty cups, we rose to continue our inspection of
+the wonders of the shop. There were ivories of all descriptions. Here was a
+two-handled sword, with a very large ivory handle, a weirdly carved scabbard,
+and wonderful steel blade. By the expression of Craig’s face, Sato knew that he
+had made a sale.
+</p>
+
+<p>
+Craig had been rummaging among some warlike instruments which Sato, with the
+instincts of a true salesman, was now displaying, and had picked up a bow. It
+was short, very strong, and made of pine wood. He held it horizontally and
+twanged the string. I looked up in time to catch a pleased expression on the
+face of Otaka.
+</p>
+
+<p>
+“Most people would have held it the other way,” commented Sato.
+</p>
+
+<p>
+Craig said nothing, but was examining an arrow, almost twenty inches long and
+thick, made of cane, with a point of metal very sharp but badly fastened. He
+fingered the deep blood groove in the scooplike head of the arrow and looked at
+it carefully.
+</p>
+
+<p>
+“I’ll take that,” he said, “only I wish it were one with the regular
+reddish-brown lump in it.”
+</p>
+
+<p>
+“Oh, but, honorable sir,” apologized Sato, “the Japanese law prohibits that,
+now. There are few of those, and they are very valuable.”
+</p>
+
+<p>
+“I suppose so,” agreed Craig. “This will do, though. You have a wonderful shop
+here, Sato. Some time, when I feel richer, I mean to come in again. No, thank
+you, you need not send them; I’ll carry them.”
+</p>
+
+<p>
+We bowed ourselves out, promising to come again when Sato received a new
+consignment from the Orient which he was expecting.
+</p>
+
+<p>
+“That other Jap is a peculiar fellow,” I observed, as we walked along uptown
+again.
+</p>
+
+<p>
+“He isn’t a Jap,” remarked Craig. “He is an Ainu, one of the aborigines who
+have been driven northward into the island of Yezo.”
+</p>
+
+<p>
+“An Ainu?” I repeated.
+</p>
+
+<p>
+“Yes. Generally thought, now, to be a white race and nearer of kin to Europeans
+than Asiatics. The Japanese have pushed them northward and are now trying to
+civilize them. They are a dirty, hairy race, but when they are brought under
+civilizing influences they adapt themselves to their environment and make very
+good servants. Still, they are on about the lowest scale of humanity.”
+</p>
+
+<p>
+“I thought Otaka was very mild,” I commented.
+</p>
+
+<p>
+“They are a most inoffensive and peaceable people usually,” he answered,
+“good-natured and amenable to authority. But they become dangerous when driven
+to despair by cruel treatment. The Japanese government is very considerate of
+them—but not all Japanese are.”

+THE ARROW POISON</h2>
+
+<p>
+Far into the night Craig was engaged in some very delicate and minute
+microscopic work in the laboratory.
+</p>
+
+<p>
+We were about to leave when there was a gentle tap on the door. Kennedy opened
+it and admitted a young man, the operative of the detective agency who had been
+shadowing Bernardo. His report was very brief, but, to me at least,
+significant. Bernardo, on his return to the museum, had evidently read the
+letter, which had agitated him very much, for a few moments later he hurriedly
+left and went downtown to the Prince Henry Hotel. The operative had casually
+edged up to the desk and overheard whom he asked for. It was Señora Herreria.
+Once again, later in the evening, he had asked for her, but she was still out.
+</p>
+
+<p>
+It was quite early the next morning, when Kennedy had resumed his careful
+microscopic work, that the telephone bell rang, and he answered it
+mechanically. But a moment later a look of intense surprise crossed his face.
+</p>
+
+<p>
+“It was from Doctor Leslie,” he announced, hanging up the receiver quickly. “He
+has a most peculiar case which he wants me to see—a woman.”
+</p>
+
+<p>
+Kennedy called a cab, and, at a furious pace, we dashed across the city and
+down to the Metropolitan Hospital, where Doctor Leslie was waiting. He met us
+eagerly and conducted us to a little room where, lying motionless on a bed, was
+a woman.
+</p>
+
+<p>
+She was a striking-looking woman, dark of hair and skin, and in life she must
+have been sensuously attractive. But now her face was drawn and contorted—with
+the same ghastly look that had been on the face of Northrop.
+</p>
+
+<p>
+“She died in a cab,” explained Doctor Leslie, “before they could get her to the
+hospital. At first they suspected the cab driver. But he seems to have proved
+his innocence. He picked her up last night on Fifth Avenue, reeling—thought she
+was intoxicated. And, in fact, he seems to have been right. Our tests have
+shown a great deal of alcohol present, but nothing like enough to have had such
+a serious effect.”
+</p>
+
+<p>
+“She told nothing of herself?” asked Kennedy.
+</p>
+
+<p>
+“No; she was pretty far gone when the cabby answered her signal. All he could
+get out of her was a word that sounded like ‘Curio-curio.’ He says she seemed
+to complain of something about her mouth and head. Her face was drawn and
+shrunken; her hands were cold and clammy, and then convulsions came on. He
+called an ambulance, but she was past saving when it arrived. The numbness
+seemed to have extended over all her body; swallowing was impossible; there was
+entire loss of her voice as well as sight, and death took place by syncope.”
+</p>
+
+<p>
+“Have you any clue to the cause of her death?” asked Craig.
+</p>
+
+<p>
+“Well, it might have been some trouble with her heart, I suppose,” remarked
+Doctor Leslie tentatively.
+</p>
+
+<p>
+“Oh, she looks strong that way. No, hardly anything organic.”
+</p>
+
+<p>
+“Well, then I thought she looked like a Mexican,” went on Doctor Leslie. “It
+might be some new tropical disease. I confess I don’t know. The fact is,” he
+added, lowering his voice, “I had my own theory about it until a few moments
+ago. That was why I called you.”
+</p>
+
+<p>
+“What do you mean?” asked Craig, evidently bent on testing his own theory by
+the other’s ignorance.
+</p>
+
+<p>
+Doctor Leslie made no answer immediately, but raised the sheet which covered
+her body and disclosed, in the fleshy part of the upper arm, a curious little
+red swollen mark with a couple of drops of darkened blood.
+</p>
+
+<p>
+“I thought at first,” he added, “that we had at last a genuine ‘poisoned
+needle’ case. You see, that looked like it. But I have made all the tests for
+curare and strychnin without results.”
+</p>
+
+<p>
+At the mere suggestion, a procession of hypodermic-needle and white-slavery
+stories flashed before me.
+</p>
+
+<p>
+“But,” objected Kennedy, “clearly this was not a case of kidnaping. It is a
+case of murder. Have you tested for the ordinary poisons?”
+</p>
+
+<p>
+Doctor Leslie shook his head. “There was no poison,” he said, “absolutely none
+that any of our tests could discover.”
+</p>
+
+<p>
+Kennedy bent over and squeezed out a few drops of liquid from the wound on a
+microscope slide, and covered them.
+</p>
+
+<p>
+“You have not identified her yet,” he added, looking up. “I think you will
+find, Leslie, that there is a Señora Herreria registered at the Prince Henry
+who is missing, and that this woman will agree with the description of her.
+Anyhow, I wish you would look it up and let me know.”
+</p>
+
+<p>
+Half an hour later, Kennedy was preparing to continue his studies with the
+microscope when Doctor Bernardo entered. He seemed most solicitous to know what
+progress was being made on the case, and, although Kennedy did not tell much,
+still he did not discourage conversation on the subject.
+</p>
+
+<p>
+When we came in the night before, Craig had unwrapped and tossed down the
+Japanese sword and the Ainu bow and arrow on a table, and it was not long
+before they attracted Bernardo’s attention.
+</p>
+
+<p>
+“I see you are a collector yourself,” he ventured, picking them up.
+</p>
+
+<p>
+“Yes,” answered Craig, offhand; “I picked them up yesterday at Sato’s. You know
+the place?”
+</p>
+
+<p>
+“Oh, yes, I know Sato,” answered the curator, seemingly without the slightest
+hesitation. “He has been in Mexico—is quite a student.”
+</p>
+
+<p>
+“And the other man, Otaka?”
+</p>
+
+<p>
+“Other man—Otaka? You mean his wife?”
+</p>
+
+<p>
+I saw Kennedy check a motion of surprise and came to the rescue with the
+natural question: “His wife—with a beard and mustache?”
+</p>
+
+<p>
+It was Bernardo’s turn to be surprised. He looked at me a moment, then saw that
+I meant it, and suddenly his face lighted up.
+</p>
+
+<p>
+“Oh,” he exclaimed, “that must have been on account of the immigration laws or
+something of the sort. Otaka is his wife. The Ainus are much sought after by
+the Japanese as wives. The women, you know, have a custom of tattooing
+mustaches on themselves. It is hideous, but they think it is beautiful.”
+</p>
+
+<p>
+“I know,” I pursued, watching Kennedy’s interest in our conversation, “but this
+was not tattooed.”
+</p>
+
+<p>
+“Well, then, it must have been false,” insisted Bernardo.
+</p>
+
+<p>
+The curator chatted a few moments, during which I expected Kennedy to lead the
+conversation around to Señora Herreria. But he did not, evidently fearing to
+show his hand.
+</p>
+
+<p>
+“What did you make of it?” I asked, when he had gone. “Is he trying to hide
+something?”
+</p>
+
+<p>
+“I think he has simplified the case,” remarked Craig, leaning back, his hands
+behind his head, gazing up at the ceiling. “Hello, here’s Leslie! What did you
+find, Doctor?” The coroner had entered with a look of awe on his face, as if
+Kennedy had directed him by some sort of necromancy.
+</p>
+
+<p>
+“It was Señora Herreria!” he exclaimed. “She has been missing from the hotel
+ever since late yesterday afternoon. What do you think of it?”
+</p>
+
+<p>
+“I think,” replied Kennedy, speaking slowly and deliberately, “that it is very
+much like the Northrop case. You haven’t taken that up yet?”
+</p>
+
+<p>
+“Only superficially. What do you make of it?” asked the coroner.
+</p>
+
+<p>
+“I had an idea that it might be aconitin poisoning,” he said.
+</p>
+
+<p>
+Leslie glanced at him keenly for a moment. “Then you’ll never prove anything in
+the laboratory,” he said.
+</p>
+
+<p>
+“There are more ways of catching a criminal, Leslie,” put in Craig, “than are
+set down in the medico-legal text-books. I shall depend on you and Jameson to
+gather together a rather cosmopolitan crowd here to-night.”
+</p>
+
+<p>
+He said it with a quiet confidence which I could not gainsay, although I did
+not understand. However, mostly with the official aid of Doctor Leslie, I
+followed out his instructions, and it was indeed a strange party that assembled
+that night. There were Doctor Bernardo; Sato, the curio dealer; Otaka, the
+Ainu, and ourselves. Mrs. Northrop, of course, could not come.
+</p>
+
+<p>
+“Mexico,” began Craig, after he had said a few words explaining why he had
+brought us together, “is full of historical treasure. To all intents and
+purposes, the government says, ‘Come and dig.’ But when there are finds, then
+the government swoops down on them for its own national museum. The finder
+scarcely gets a chance to export them. However, now seemed to be the time to
+Professor Northrop to smuggle his finds out of the country.
+</p>
+
+<p>
+“But evidently it could not be done without exciting all kinds of rumors and
+suspicions. Stories seem to have spread far and fast about what he had
+discovered. He realized the unsettled condition of the country—perhaps wanted
+to confirm his reading of a certain inscription by consultation with one
+scholar whom he thought he could trust. At any rate, he came home.”
+</p>
+
+<p>
+Kennedy paused, making use of the silence for emphasis. “You have all read of
+the wealth that Cortez found in Mexico. Where are the gold and silver of the
+<i>conquistadores?</i> Gone to the melting pot, centuries ago. But is there
+none left? The Indians believe so. There are persons who would stop at
+nothing—even at murder of American professors, murder of their own comrades, to
+get at the secret.”
+</p>
+
+<p>
+He laid his hand almost lovingly on his powerful little microscope as he
+resumed on another line of evidence.
+</p>
+
+<p>
+“And while we are on the subject of murders, two very similar deaths have
+occurred,” he went on. “It is of no use to try to gloss them over. Frankly, I
+suspected that they might have been caused by aconite poisoning. But, in the
+case of such poisoning, not only is the lethal dose very small but our chemical
+methods of detection are <i>nil</i>. The dose of the active principle, aconitin
+nitrate, is about one six-hundredth of a grain. There are no color tests, no
+reactions, as in the case of the other organic poisons.”
+</p>
+
+<p>
+I wondered what he was driving at. Was there, indeed, no test? Had the murderer
+used the safest of poisons—one that left no clue? I looked covertly at Sato’s
+face. It was impassive. Doctor Bernardo was visibly uneasy as Kennedy
+proceeded. Cool enough up to the time of the mention of the treasure, I
+fancied, now, that he was growing more and more nervous.
+</p>
+
+<p>
+Craig laid down on the table the reed stick with the little darkened cylinder
+on the end.
+</p>
+
+<p>
+“That,” he said, “is a little article which I picked up beneath Northrop’s
+window yesterday. It is a piece of <i>anno-noki</i>, or <i>bushi</i>.” I
+fancied I saw just a glint of satisfaction in Otaka’s eyes.
+</p>
+
+<p>
+“Like many barbarians,” continued Craig, “the Ainus from time immemorial have
+prepared virulent poisons with which they charged their weapons of the chase
+and warfare. The formulas for the preparations, as in the case of other arrow
+poisons of other tribes, are known only to certain members, and the secret is
+passed down from generation to generation as an heirloom, as it were. But in
+this case it is no longer a secret. It has now been proved that the active
+principle of this poison is aconite.”
+</p>
+
+<p>
+“If that is the case,” broke in Doctor Leslie, “it is hopeless to connect
+anyone directly in that way with these murders. There is no test for aconitin.”
+</p>
+
+<p>
+I thought Sato’s face was more composed and impassive than ever. Doctor
+Bernardo, however, was plainly excited.
+</p>
+
+<p>
+“What—no test—<i>none?</i>” asked Kennedy, leaning forward eagerly. Then, as if
+he could restrain the answer to his own question no longer, he shot out: “How
+about the new starch test just discovered by Professor Reichert, of the
+University of Pennsylvania? Doubtless you never dreamed that starch may be a
+means of detecting the nature of a poison in obscure cases in criminology,
+especially in cases where the quantity of poison necessary to cause death is so
+minute that no trace of it can be found in the blood.
+</p>
+
+<p>
+“The starch method is a new and extremely inviting subject to me. The
+peculiarities of the starch of any plant are quite as distinctive of the plant
+as are those of the hemoglobin crystals in the blood of an animal. I have
+analyzed the evidence of my microscope in this case thoroughly. When the arrow
+poison is introduced subcutaneously—say, by a person shooting a poisoned dart,
+which he afterward removes in order to destroy the evidence—the lethal
+constituents are rapidly absorbed.
+</p>
+
+<p>
+“But the starch remains in the wound. It can be recovered and studied
+microscopically and can be definitely recognized. Doctor Reichert has published
+a study of twelve hundred such starches from all sorts of plants. In this case,
+it not only proves to be aconitin but the starch granules themselves can be
+recognized. They came from this piece of arrow poison.”
+</p>
+
+<p>
+Every eye was fixed on him now.
+</p>
+
+<p>
+“Besides,” he rapped out, “in the soft soil beneath the window of Professor
+Northrop’s room, I found footprints. I have only to compare the impressions I
+took there and those of the people in this room, to prove that, while the real
+murderer stood guard below the window, he sent some one more nimble up the rain
+pipe to shoot the poisoned dart at Professor Northrop, and, later, to let down
+a rope by which he, the instigator, could gain the room, remove the dart, and
+obtain the key to the treasure he sought.”
+</p>
+
+<p>
+Kennedy was looking straight at Professor Bernardo.
+</p>
+
+<p>
+“A friend of mine in Mexico has written me about an inscription,” he burst out.
+“I received the letter only to-day. As nearly as I can gather, there was an
+impression that some of Northrop’s stuff would be valuable in proving the
+alleged kinship between Mexico and Japan, perhaps to arouse hatred of the
+United States.”
+</p>
+
+<p>
+“Yes—that is all very well,” insisted Kennedy. “But how about the treasure?”
+</p>
+
+<p>
+“Treasure?” repeated Bernardo, looking from one of us to another.
+</p>
+
+<p>
+“Yes,” pursued Craig relentlessly, “the treasure. You are an expert in reading
+the hieroglyphics. By your own statement, you and Northrop had been going over
+the stuff he had sent up. You know it.”
+</p>
+
+<p>
+Bernardo gave a quick glance from Kennedy to me. Evidently he saw that the
+secret was out.
+</p>
+
+<p>
+“Yes,” he said huskily, in a low tone, “Northrop and I were to follow the
+directions after we had plotted them out and were to share it together on the
+next expedition, which I could direct as a Mexican without so much suspicion. I
+should still have shared it with his widow if this unfortunate affair had not
+exposed the secret.”
+</p>
+
+<p>
+Bernardo had risen earnestly.
+</p>
+
+<p>
+“Kennedy,” he cried, “before God, if you will get back that stone and keep the
+secret from going further than this room, I will prove what I have said by
+dividing the Mixtec treasure with Mrs. Northrop and making her one of the
+richest widows in the country!”
+</p>
+
+<p>
+“That is what I wanted to be sure of,” nodded Craig. “Bernardo, Señora
+Herreria, of whom your friend wrote to you from Mexico, has been murdered in
+the same way that Professor Northrop was. Otaka was sent by her husband to
+murder Northrop, in order that they might obtain the so-called ‘Pillar of
+Death’ and the key to the treasure. Then, when the <i>señora</i> was no doubt
+under the influence of <i>sake</i> in the pretty little Oriental bower at the
+curio shop, a quick jab, and Otaka had removed one who shared the secret with
+them.”
+</p>
+
+<p>
+He had turned and faced the pair.
+</p>
+
+<p>
+“Sato,” he added, “you played on the patriotism of the <i>señora</i> until you
+wormed from her the treasure secret. Evidently rumors of it had spread from
+Mexican Indians to Japanese visitors. And then, Otaka, all jealousy over one
+whom she, no doubt, justly considered a rival, completed your work by sending
+her forth to die, unknown, on the street. Walter, ring up First Deputy
+O’Connor. The stone is hidden somewhere in the curio shop. We can find it
+without Sato’s help. The quicker such a criminal is lodged safely in jail, the
+better for humanity.”
+</p>
+
+<p>
+Sato was on his feet, advancing cautiously toward Craig. I knew the dangers,
+now, of <i>anno-noki</i>, as well as the wonders of <i>jujutsu</i>, and, with a
+leap, I bounded past Bernardo and between Sato and Kennedy.
+</p>
+
+<p>
+How it happened, I don’t know, but, an instant later, I was sprawling.
+</p>
+
+<p>
+Before I could recover myself, before even Craig had a chance to pull the
+hair-trigger of his automatic, Sato had seized the Ainu arrow poison from the
+table, had bitten the little cylinder in half, and had crammed the other half
+into the mouth of Otaka.

+<h2><a name="chap13"></a>CHAPTER XIII<br/>
+THE RADIUM ROBBER</h2>
+
+<p>
+Kennedy simply reached for the telephone and called an ambulance. But it was
+purely perfunctory. Dr. Leslie himself was the only official who could handle
+Sato’s case now.
+</p>
+
+<p>
+We had planned a little vacation for ourselves, but the planning came to
+naught. The next night we spent on a sleeper. That in itself is work to me.
+</p>
+
+<p>
+It all came about through a hurried message from Murray Denison, president of
+the Federal Radium Corporation. Nothing would do but that he should take both
+Kennedy and myself with him post-haste to Pittsburgh at the first news of what
+had immediately been called “the great radium robbery.”
+</p>
+
+<p>
+Of course the newspapers were full of it. The very novelty of an ultra-modern
+cracksman going off with something worth upward of a couple of hundred thousand
+dollars—and all contained in a few platinum tubes which could be tucked away in
+a vest pocket—had something about it powerfully appealing to the imagination.
+</p>
+
+<p>
+“Most ingenious, but, you see, the trouble with that safe is that it was built
+to keep radium <i>in</i>—not cracksmen <i>out</i>,” remarked Kennedy, when
+Denison had rushed us from the train to take a look at the little safe in the
+works of the Corporation.
+</p>
+
+<p>
+“Breaking into such a safe as this,” added Kennedy, after a cursory
+examination, “is simple enough, after all.”
+</p>
+
+<p>
+It was, however, a remarkably ingenious contrivance, about three feet in height
+and of a weight of perhaps a ton and a half, and all to house something
+weighing only a few grains.
+</p>
+
+<p>
+“But,” Denison hastened to explain, “we had to protect the radium not only
+against burglars, but, so to speak, against itself. Radium emanations pass
+through steel and experiments have shown that the best metal to contain them is
+lead. So, the difficulty was solved by making a steel outer case enclosing an
+inside leaden shell three inches thick.”
+</p>
+
+<p>
+Kennedy had been toying thoughtfully with the door.
+</p>
+
+<p>
+“Then the door, too, had to be contrived so as to prevent any escape of the
+emanations through joints. It is lathe turned and circular, a ‘dead fit.’ By
+means of a special contrivance any slight looseness caused by wear and tear of
+closing can be adjusted. And another feature. That is the appliance for
+preventing the loss of emanation when the door is opened. Two valves have been
+inserted into the door and before it is opened tubes with mercury are passed
+through which collect and store the emanation.”
+</p>
+
+<p>
+“All very nice for the radium,” remarked Craig cheerfully. “But the fellow had
+only to use an electric drill and the gram or more of radium was his.”
+</p>
+
+<p>
+“I know that—now,” ruefully persisted Denison. “But the safe was designed for
+us specially. The fellow got into it and got away, as far as I can see, without
+leaving a clue.”
+</p>
+
+<p>
+“Except one, of course,” interrupted Kennedy quickly.
+</p>
+
+<p>
+Denison looked at him a moment keenly, then nodded and said, “Yes—you are
+right. You mean one which he must bear on himself?”
+</p>
+
+<p>
+“Exactly. You can’t carry a gram or more of radium bromide long with impunity.
+The man to look for is one who in a few days will have somewhere on his body a
+radium burn which will take months to heal. The very thing he stole is a
+veritable Frankenstein’s monster bent on the destruction of the thief himself!”
+</p>
+
+<p>
+Kennedy had meanwhile picked up one of the Corporation’s circulars lying on a
+desk. He ran his eye down the list of names.
+</p>
+
+<p>
+“So, Hartley Haughton, the broker, is one of your stockholders,” mused Kennedy.
+</p>
+
+<p>
+“Not only one but <i>the</i> one,” replied Denison with obvious pride.
+</p>
+
+<p>
+Haughton was a young man who had come recently into his fortune, and, while no
+one believed it to be large, he had cut quite a figure in Wall Street.
+</p>
+
+<p>
+“You know, I suppose,” added Denison, “that he is engaged to Felicie Woods, the
+daughter of Mrs. Courtney Woods?”
+</p>
+
+<p>
+Kennedy did not, but said nothing.
+</p>
+
+<p>
+“A most delightful little girl,” continued Denison thoughtfully. “I have known
+Mrs. Woods for some time. She wanted to invest, but I told her frankly that
+this is, after all, a speculation. We may not be able to swing so big a
+proposition, but, if not, no one can say we have taken a dollar of money from
+widows and orphans.”
+</p>
+
+<p>
+“I should like to see the works,” nodded Kennedy approvingly.
+</p>
+
+<p>
+“By all means.”
+</p>
+
+<p>
+The plant was a row of long low buildings of brick on the outskirts of the
+city, once devoted to the making of vanadium steel. The ore, as Denison
+explained, was brought to Pittsburgh because he had found here already a
+factory which could readily be turned into a plant for the extraction of
+radium. Huge baths and vats and crucibles for the various acids and alkalis and
+other processes used in treating the ore stood at various points.
+</p>
+
+<p>
+“This must be like extracting gold from sea water,” remarked Kennedy jocosely,
+impressed by the size of the plant as compared to the product.
+</p>
+
+<p>
+“Except that after we get through we have something infinitely more precious
+than gold,” replied Denison, “something which warrants the trouble and outlay.
+Yes, the fact is that the percentage of radium in all such ores is even less
+than of gold in sea water.”
+</p>
+
+<p>
+“Everything seems to be most carefully guarded,” remarked Kennedy as we
+concluded our tour of the well-appointed works.
+</p>
+
+<p>
+He had gone over everything in silence, and now at last we had returned to the
+safe.
+</p>
+
+<p>
+“Yes,” he repeated slowly, as if confirming his original impression, “such an
+amount of radium as was stolen wouldn’t occasion immediate discomfort to the
+thief, I suppose, but later no infernal machine could be more dangerous to
+him.”
+</p>
+
+<p>
+I pictured to myself the series of fearful works of mischief and terror that
+might follow, a curse on the thief worse than that of the weirdest curses of
+the Orient, the danger to the innocent, and the fact that in the hands of a
+criminal it was an instrument for committing crimes that might defy detection.
+</p>
+
+<p>
+“There is nothing more to do here now,” he concluded. “I can see nothing for
+the present except to go back to New York. The telltale burn may not be the
+only clue, but if the thief is going to profit by his spoils we shall hear
+about it best in New York or by cable from London, Paris, or some other
+European city.”
+</p>
+
+<p>
+Our hurried departure from New York had not given us a chance to visit the
+offices of the Radium Corporation for the distribution of the salts themselves.
+They were in a little old office building on William Street, near the drug
+district and yet scarcely a moment’s walk from the financial district.
+</p>
+
+<p>
+“Our head bookkeeper, Miss Wallace, is ill,” remarked Denison when we arrived
+at the office, “but if there is anything I can do to help you, I shall be glad
+to do it. We depend on Miss Wallace a great deal. Haughton says she is the
+brains of the office.”
+</p>
+
+<p>
+Kennedy looked about the well-appointed suite curiously.
+</p>
+
+<p>
+“Is this another of those radium safes?” he asked, approaching one similar in
+appearance to that which had been broken open already.
+</p>
+
+<p>
+“Yes, only a little larger.”
+</p>
+
+<p>
+“How much is in it?”
+</p>
+
+<p>
+“Most of our supply. I should say about two and a half grams. Miss Wallace has
+the record.”
+</p>
+
+<p>
+“It is of the same construction, I presume,” pursued Kennedy. “I wonder whether
+the lead lining fits closely to the steel?”
+</p>
+
+<p>
+“I think not,” considered Denison. “As I remember there was a sort of
+insulating air cushion or something of the sort.”
+</p>
+
+<p>
+Denison was quite eager to show us about. In fact ever since he had hustled us
+out to view the scene of the robbery, his high nervous tension had given us
+scarcely a moment’s rest. For hours he had talked radium, until I felt that he,
+like his metal, must have an inexhaustible emanation of words. He was one of
+those nervous, active little men, a born salesman, whether of ribbons or
+radium.
+</p>
+
+<p>
+“We have just gone into furnishing radium water,” he went on, bustling about
+and patting a little glass tank.
+</p>
+
+<p>
+I looked closely and could see that the water glowed in the dark with a
+peculiar phosphorescence.
+</p>
+
+<p>
+“The apparatus for the treatment,” he continued, “consists of two glass and
+porcelain receptacles. Inside the larger receptacle is placed the smaller,
+which contains a tiny quantity of radium. Into the larger receptacle is poured
+about a gallon of filtered water. The emanation from that little speck of
+radium is powerful enough to penetrate its porcelain holder and charge the
+water with its curative properties. From a tap at the bottom of the tank the
+patient draws the number of glasses of water a day prescribed. For such
+purposes the emanation within a day or two of being collected is as good as
+radium itself. Why, this water is five thousand times as radioactive as the
+most radioactive natural spring water.”
+</p>
+
+<p>
+“You must have control of a comparatively large amount of the metal,” suggested
+Kennedy.
+</p>
+
+<p>
+“We are, I believe, the largest holders of radium in the world,” he answered.
+“I have estimated that all told there are not much more than ten grams, of
+which Madame Curie has perhaps three, while Sir Ernest Cassel of London is the
+holder of perhaps as much. We have nearly four grams, leaving about six or
+seven for the rest of the world.”
+</p>
+
+<p>
+Kennedy nodded and continued to look about.
+</p>
+
+<p>
+“The Radium Corporation,” went on Denison, “has several large deposits of
+radioactive ore in Utah in what is known as the Poor Little Rich Valley, a
+valley so named because from being about the barrenest and most unproductive
+mineral or agricultural hole in the hills, the sudden discovery of the
+radioactive deposits has made it almost priceless.”
+</p>
+
+<p>
+He had entered a private office and was looking over some mail that had been
+left on his desk during his absence.
+</p>
+
+<p>
+“Look at this,” he called, picking up a clipping from a newspaper which had
+been laid there for his attention. “You see, we have them aroused.”
+</p>
+
+<p>
+We read the clipping together hastily:
+</p>
+
+<h5>PLAN TO CORNER WORLD’S RADIUM</h5>
+
+<p>
+L<small>ONDON</small>.—Plans are being matured to form a large corporation for
+the monopoly of the existing and future supply of radium throughout the world.
+The company is to be called Universal Radium, Limited, and the capital of ten
+million dollars will be offered for public subscription at par simultaneously
+in London, Paris and New York.
+</p>
+
+<p>
+The company’s business will be to acquire mines and deposits of radioactive
+substances as well as the control of patents and processes connected with the
+production of radium. The outspoken purpose of the new company is to obtain a
+world-wide monopoly and maintain the price.
+</p>
+
+<p class="p2">
+“Ah—a competitor,” commented Kennedy, handing back the clipping.
+</p>
+
+<p>
+“Yes. You know radium salts used always to come from Europe. Now we are getting
+ready to do some exporting ourselves. Say,” he added excitedly, “there’s an
+idea, possibly, in that.”
+</p>
+
+<p>
+“How?” queried Craig.
+</p>
+
+<p>
+“Why, since we should be the principal competitors to the foreign mines,
+couldn’t this robbery have been due to the machinations of these schemers? To
+my mind, the United States, because of its supply of radium-bearing ores, will
+have to be reckoned with first in cornering the market. This is the point,
+Kennedy. Would those people who seem to be trying to extend their new company
+all over the world stop at anything in order to cripple us at the start?”
+</p>
+
+<p>
+How much longer Denison would have rattled on in his effort to explain the
+robbery, I do not know. The telephone rang and a reporter from the
+<i>Record</i>, who had just read my own story in the <i>Star</i>, asked for an
+interview. I knew that it would be only a question of minutes now before the
+other men were wearing a path out on the stairs, and we managed to get away
+before the onrush began.
+</p>
+
+<p>
+“Walter,” said Kennedy, as soon as we had reached the street. “I want to get in
+touch with Halsey Haughton. How can it be done?”
+</p>
+
+<p>
+I could think of nothing better at that moment than to inquire at the
+<i>Star’s</i> Wall Street office, which happened to be around the corner. I
+knew the men down there intimately, and a few minutes later we were whisked up
+in the elevator to the office.
+</p>
+
+<p>
+They were as glad to see me as I was to see them, for the story of the robbery
+had interested the financial district perhaps more than any other.
+</p>
+
+<p>
+“Where can I find Halsey Haughton at this hour?” I asked.
+</p>
+
+<p>
+“Say,” exclaimed one of the men, “what’s the matter? There have been all kinds
+of rumors in the Street about him to-day. Did you know he was ill?”
+</p>
+
+<p>
+“No,” I answered. “Where is he?”
+</p>
+
+<p>
+“Out at the home of his fiancee, who is the daughter of Mrs. Courtney Woods, at
+Glenclair.”
+</p>
+
+<p>
+“What’s the matter?” I persisted.
+</p>
+
+<p>
+“That’s just it. No one seems to know. They say—well—they say he has a cancer.”
+</p>
+
+<p>
+Halsey Haughton suffering from cancer? It was such an uncommon thing to hear of
+a young man that I looked up quickly in surprise. Then all at once it flashed
+over me that Denison and Kennedy had discussed the matter of burns from the
+stolen radium. Might not this be, instead of cancer, a radium burn?
+</p>
+
+<p>
+Kennedy, who had been standing a little apart from me while I was talking with
+the boys, signaled to me with a quick glance not to say too much, and a few
+minutes later we were on the street again.
+</p>
+
+<p>
+I knew without being told that he was bound by the next train to the pretty
+little New Jersey suburb of Glenclair.
+</p>
+
+<p>
+It was late when we arrived, yet Kennedy had no hesitation in calling at the
+quaint home of Mrs. Courtney Woods on Woodridge Avenue.
+</p>
+
+<p>
+Mrs. Woods, a well-set-up woman of middle age, who had retained her youth and
+good looks in a remarkable manner, met us in the foyer. Briefly, Kennedy
+explained that we had just come in from Pittsburgh with Mr. Denison and that it
+was very important that we should see Haughton at once.
+</p>
+
+<p>
+We had hardly told her the object of our visit when a young woman of perhaps
+twenty-two or three, a very pretty girl, with all the good looks of her mother
+and a freshness which only youth can possess, tiptoed quietly downstairs. Her
+face told plainly that she was deeply worried over the illness of her fiance.
+</p>
+
+<p>
+“Who is it, mother?” she whispered from the turn in the stairs. “Some gentlemen
+from the company? Hartley’s door was open when the bell rang, and he thought he
+heard something said about the Pittsburgh affair.”
+</p>
+
+<p>
+Though she had whispered, it had not been for the purpose of concealing
+anything from us, but rather that the keen ears of her patient might not catch
+the words. She cast an inquiring glance at us.
+</p>
+
+<p>
+“Yes,” responded Kennedy in answer to her look, modulating his tone. “We have
+just left Mr. Denison at the office. Might we see Mr. Haughton for a moment? I
+am sure that nothing we can say or do will be as bad for him as our going away,
+now that he knows that we are here.”
+</p>
+
+<p>
+The two women appeared to consult for a moment.
+</p>
+
+<p>
+“Felicie,” called a rather nervous voice from the second floor, “is it some one
+from the company?”
+</p>
+
+<p>
+“Just a moment, Hartley,” she answered, then, lower to her mother, added, “I
+don’t think it can do any harm, do you, mother?”
+</p>
+
+<p>
+“You remember the doctor’s orders, my dear.”
+</p>
+
+<p>
+Again the voice called her.
+</p>
+
+<p>
+“Hang the doctor’s orders,” the girl exclaimed, with an air of almost
+masculinity. “It can’t be half so bad as to have him worry. Will you promise
+not to stay long? We expect Dr. Bryant in a few moments, anyway.”
+</p>

+THE SPINTHARISCOPE</h2>
+
+<p>
+We followed her upstairs and into Haughton’s room, where he was lying in bed,
+propped up by pillows. Haughton certainly was ill. There was no mistake about
+that. He was a tall, gaunt man with an air about him that showed that he found
+illness very irksome. Around his neck was a bandage, and some adhesive tape at
+the back showed that a plaster of some sort had been placed there.
+</p>
+
+<p>
+As we entered his eyes traveled restlessly from the face of the girl to our own
+in an inquiring manner. He stretched out a nervous hand to us, while Kennedy in
+a few short sentences explained how we had become associated with the case and
+what we had seen already.
+</p>
+
+<p>
+“And there is not a clue?” he repeated as Craig finished.
+</p>
+
+<p>
+“Nothing tangible yet,” reiterated Kennedy. “I suppose you have heard of this
+rumor from London of a trust that is going into the radium field
+internationally?”
+</p>
+
+<p>
+“Yes,” he answered, “that is the thing you read to me in the morning papers,
+you remember, Felicie. Denison and I have heard such rumors before. If it is a
+fight, then we shall give them a fight. They can’t hold us up, if Denison is
+right in thinking that they are at the bottom of this—this robbery.”
+</p>
+
+<p>
+“Then you think he may be right?” shot out Kennedy quickly.
+</p>
+
+<p>
+Haughton glanced nervously from Kennedy to me.
+</p>
+
+<p>
+“Really,” he answered, “you see how impossible it is for me to have an opinion?
+You and Denison have been over the ground. You know much more about it than I
+do. I am afraid I shall have to defer to you.”
+</p>
+
+<p>
+Again we heard the bell downstairs, and a moment later a cheery voice, as Mrs.
+Woods met some one down in the foyer, asked, “How is the patient to-night?”
+</p>
+
+<p>
+We could not catch the reply.
+</p>
+
+<p>
+“Dr. Bryant, my physician,” put in Haughton. “Don’t go. I will assume the
+responsibility for your being here. Hello, Doctor. Why, I’m much the same
+to-night, thank you. At least no worse since I took your advice and went to
+bed.”
+</p>
+
+<p>
+Dr. Bryant was a bluff, hearty man, with the personal magnetism which goes with
+the making of a successful physician. He had mounted the stairs quietly but
+rapidly, evidently prepared to see us.
+</p>
+
+<p>
+“Would you mind waiting in this little dressing room?” asked the doctor,
+motioning to another, smaller room adjoining.
+</p>
+
+<p>
+He had taken from his pocket a little instrument with a dial face like a watch,
+which he attached to Haughton’s wrist. “A pocket instrument to measure blood
+pressure,” whispered Craig, as we entered the little room.
+</p>
+
+<p>
+While the others were gathered about Haughton, we stood in the next room, out
+of earshot. Kennedy had leaned his elbow on a chiffonier. As he looked about
+the little room, more from force of habit than because he thought he might
+discover anything, Kennedy’s eye rested on a glass tray on the top in which lay
+some pins, a collar button or two, which Haughton had apparently just taken
+off, and several other little unimportant articles.
+</p>
+
+<p>
+Kennedy bent over to look at the glass tray more closely, a puzzled look
+crossed his face, and with a glance at the other room he gathered up the tray
+and its contents.
+</p>
+
+<p>
+“Keep up a good courage,” said Dr. Bryant. “You’ll come out all right,
+Haughton.” Then as he left the bedroom he added to us, “Gentlemen, I hope you
+will pardon me, but if you could postpone the remainder of your visit until a
+later day, I am sure you will find it more satisfactory.”
+</p>
+
+<p>
+There was an air of finality about the doctor, though nothing unpleasant in it.
+We followed him down the stairs, and as we did so, Felicie, who had been
+waiting in a reception room, appeared before the portieres, her earnest eyes
+fixed on his kindly face.
+</p>
+
+<p>
+“Dr. Bryant,” she appealed, “is he—is he, really—so badly?”
+</p>
+
+<p>
+The Doctor, who had apparently known her all her life, reached down and took
+one of her hands, patting it with his own in a fatherly way. “Don’t worry,
+little girl,” he encouraged. “We are going to come out all right—all right.”
+</p>
+
+<p>
+She turned from him to us and, with a bright forced smile which showed the
+stuff she was made of, bade us good night.
+</p>
+
+<p>
+Outside, the Doctor, apparently regretting that he had virtually forced us out,
+paused before his car. “Are you going down toward the station? Yes? I am going
+that far. I should be glad to drive you there.”
+</p>
+
+<p>
+Kennedy climbed into the front seat, leaving me in the rear where the wind
+wafted me their brief conversation as we sped down Woodbridge Avenue.
+</p>
+
+<p>
+“What seems to be the trouble?” asked Craig.
+</p>
+
+<p>
+“Very high blood pressure, for one thing,” replied the Doctor frankly.
+</p>
+
+<p>
+“For which the latest thing is the radium water cure, I suppose?” ventured
+Kennedy.
+</p>
+
+<p>
+“Well, radioactive water is one cure for hardening of the arteries. But I
+didn’t say he had hardening of the arteries. Still, he is taking the water,
+with good results. You are from the company?”
+</p>
+
+<p>
+Kennedy nodded.
+</p>
+
+<p>
+“It was the radium water that first interested him in it. Why, we found a
+pressure of 230 pounds, which is frightful, and we have brought it down to 150,
+not far from normal.”
+</p>
+
+<p>
+“Still that could have nothing to do with the sore on his neck,” hazarded
+Kennedy.
+</p>
+
+<p>
+The Doctor looked at him quickly, then ahead at the path of light which his
+motor shed on the road.
+</p>
+
+<p>
+He said nothing, but I fancied that even he felt there was something strange in
+his silence over the new complication. He did not give Kennedy a chance to ask
+whether there were any other such sores.
+</p>
+
+<p>
+“At any rate,” he said, as he throttled down his engine with a flourish before
+the pretty little Glenclair station, “that girl needn’t worry.”
+</p>
+
+<p>
+There was evidently no use in trying to extract anything further from him. He
+had said all that medical ethics or detective skill could get from him. We
+thanked him and turned to the ticket window to see how long we should have to
+wait.
+</p>
+
+<p>
+“Either that doctor doesn’t know what he is talking about or he is concealing
+something,” remarked Craig, as we paced up and down the platform. “I am
+inclined to read the enigma in the latter way.”
+</p>
+
+<p>
+Nothing more passed between us during the journey back, and we hurried directly
+to the laboratory, late as it was. Kennedy had evidently been revolving
+something over and over in his mind, for the moment he had switched on the
+light, he unlocked one of his air-and dust-proof cabinets and took from it an
+instrument which he placed on a table before him.
+</p>
+
+<p>
+It was a peculiar-looking instrument, like a round glass electric battery with
+a cylinder atop, smaller and sticking up like a safety valve. On that were an
+arm, a dial, and a lens fixed in such a way as to read the dial. I could not
+see what else the rather complicated little apparatus consisted of, but inside,
+when Kennedy brought near it the pole of a static electric machine two delicate
+thin leaves of gold seemed to fly wide apart when it was charged.
+</p>
+
+<p>
+Kennedy had brought the glass tray near the thing. Instantly the leaves
+collapsed and he made a reading through the lens.
+</p>
+
+<p>
+“What is it?” I asked.
+</p>
+
+<p>
+“A radioscope,” he replied, still observing the scale. “Really a very sensitive
+gold leaf electroscope, devised by one of the students of Madame Curie. This
+method of detection is far more sensitive even than the spectroscope.”
+</p>
+
+<p>
+“What does it mean when the leaves collapse?” I asked.
+</p>
+
+<p>
+“Radium has been near that tray,” he answered. “It is radioactive. I suspected
+it first when I saw that violet color. That is what radium does to that kind of
+glass. You see, if radium exists in a gram of inactive matter only to the
+extent of one in ten-thousand million parts its presence can be readily
+detected by this radioscope, and everything that has been rendered radioactive
+is the same. Ordinarily the air between the gold leaves is insulating. Bringing
+something radioactive near them renders the air a good conductor and the leaves
+fall under the radiation.”
+</p>
+
+<p>
+“Wonderful!” I exclaimed, marveling at the delicacy of it.
+</p>
+
+<p>
+“Take radium water,” he went on, “sufficiently impregnated with radium
+emanations to be luminous in the dark, like that water of Denison’s. It would
+do the same. In fact all mineral waters and the so-called curarive muds like
+fango are slightly radioactive. There seems to be a little radium everywhere on
+earth that experiments have been made, even in the interiors of buildings. It
+is ubiquitous. We are surrounded and permeated by radiations—that soil out
+there on the campus, the air of this room, all. But,” he added contemplatively,
+“there is something different about that tray. A lot of radium has been near
+that, and recently.”
+</p>
+
+<p>
+“How about that bandage about Haughton’s neck?” I asked suddenly. “Do you think
+radium could have had anything to do with that?” “Well, as to burns, there is
+no particular immediate effect usually, and sometimes even up to two weeks or
+more, unless the exposure has been long and to a considerable quantity. Of
+course radium keeps itself three or four degrees warmer than other things about
+it constantly. But that isn’t what does the harm. It is continually emitting
+little corpuscles, which I’ll explain some other time, traveling all the way
+from twenty to one hundred and thirty thousand miles a second, and these
+corpuscles blister and corrode the flesh like quick-moving missiles bombarding
+it. The gravity of such lesions increases with the purity of the radium. For
+instance I have known an exposure of half an hour to a comparatively small
+quantity through a tube, a box and the clothes to produce a blister fifteen
+days later. Curie said he wouldn’t trust himself in a room with a kilogram of
+it. It would destroy his eyesight, burn off his skin and kill him eventually.
+Why, even after a slight exposure your clothes are radioactive—the electroscope
+will show that.”
+</p>
+
+<p>
+He was still fumbling with the glass plate and the various articles on it.
+</p>
+
+<p>
+“There’s something very peculiar about all this,” he muttered, almost to
+himself.
+</p>
+
+<p>
+Tired by the quick succession of events of the past two days, I left Kennedy
+still experimenting in his laboratory and retired, still wondering when the
+real clue was to develop. Who could it have been who bore the tell-tale burn?
+Was the mark hidden by the bandage about Haughton’s neck the brand of the
+stolen tubes? Or were there other marks on his body which we could not see?
+</p>
+
+<p>
+No answer came to me, and I fell asleep and woke up without a radiation of
+light on the subject. Kennedy spent the greater part of the day still at work
+at his laboratory, performing some very delicate experiments. Finding nothing
+to do there, I went down to the <i>Star</i> office and spent my time reading
+the reports that came in from the small army of reporters who had been assigned
+to run down clues in the case which was the sensation of the moment. I have
+always felt my own lips sealed in such cases, until the time came that the
+story was complete and Kennedy released me from any further need of silence.
+The weird and impossible stories which came in not only to the <i>Star</i> but
+to the other papers surely did make passable copy in this instance, but with my
+knowledge of the case I could see that not one of them brought us a step nearer
+the truth.
+</p>
+
+<p>
+One thing which uniformly puzzled the newspapers was the illness of Haughton
+and his enforced idleness at a time which was of so much importance to the
+company which he had promoted and indeed very largely financed. Then, of
+course, there was the romantic side of his engagement to Felicie Woods.
+</p>
+
+<p>
+Just what connection Felicie Woods had with the radium robbery if any, I was
+myself unable quite to fathom. Still, that made no difference to the papers.
+She was pretty and therefore they published her picture, three columns deep,
+with Haughton and Denison, who were intimately concerned with the real loss in
+little ovals perhaps an inch across and two inches in the opposite dimension.
+</p>
+
+<p>
+The late afternoon news editions had gone to press, and I had given up in
+despair, determined to go up to the laboratory and sit around idly watching
+Kennedy with his mystifying experiments, in preference to waiting for him to
+summon me.
+</p>
+
+<p>
+I had scarcely arrived and settled myself to an impatient watch, when an
+automobile drove up furiously, and Denison himself, very excited, jumped out
+and dashed into the laboratory.
+</p>
+
+<div class="fig" style="width:100%;">

+<p class="caption">Denison himself, very excited, jumped out and dashed into
+the laboratory.</p>
+</div>
+
+<p>
+“What’s the matter?” asked Kennedy, looking up from a test tube which he had
+been examining, with an air for all the world expressive of “Why so hot, little
+man?”
+</p>
+
+<p>
+“I’ve had a threat,” ejaculated Denison.
+</p>
+
+<p>
+He laid on one of the laboratory tables a letter, without heading and without
+signature, written in a disguised hand, with an evident attempt to simulate the
+cramped script of a foreign penmanship.
+</p>
+
+<p class="letter">
+“I know who did the Pittsburgh job. The same party is out to ruin Federal
+Radium. Remember Pittsburgh and be prepared!
+</p>
+
+<p class="right">
+“A S<small>TOCKHOLDER</small>.”
+</p>
+
+<p>
+“Well?” demanded Kennedy, looking up.
+</p>
+
+<p>
+“That can have only one meaning,” asserted Denison.
+</p>
+
+<p>
+“What is that?” inquired Kennedy coolly, as if to confirm his own
+interpretation.
+</p>
+
+<p>
+“Why, another robbery—here in New York, of course.”
+</p>
+
+<p>
+“But who would do it?” I asked.
+</p>
+
+<p>
+“Who?” repeated Denison. “Some one representing that European combine, of
+course. That is only part of the Trust method—ruin of competitors whom they
+cannot absorb.”
+</p>
+
+<p>
+“Then you have refused to go into the combine? You know who is backing it?”
+</p>
+
+<p>
+“No—no,” admitted Denison reluctantly. “We have only signified our intent to go
+it alone, as often as anyone either with or without authority has offered to
+buy us out. No, I do not even know who the people are. They never act in the
+open. The only hints I have ever received were through perfectly reputable
+brokers acting for others.”
+</p>
+
+<p>
+“Does Haughton know of this note?” asked Kennedy.
+</p>
+
+<p>
+“Yes. As soon as I received it, I called him up.”
+</p>
+
+<p>
+“What did he say?”
+</p>
+
+<p>
+“He said to disregard it. But—you know what condition he is in. I don’t know
+what to do, whether to surround the office by a squad of detectives or remove
+the radium to a regular safety deposit vault, even at the loss of the
+emanation. Haughton has left it to me.”
+</p>
+
+<p>
+Suddenly the thought flashed across my mind that perhaps Haughton could act in
+this uninterested fashion because he had no fear of ruin either way. Might he
+not be playing a game with the combination in which he had protected himself so
+that he would win, no matter what happened?
+</p>
+
+<p>
+“What shall I do?” asked Denison. “It is getting late.”
+</p>
+
+<p>
+“Neither,” decided Kennedy.
+</p>
+
+<p>
+Denison shook his head. “No,” he said, “I shall have some one watch there,
+anyhow.”

+THE ASPHYXIATING SAFE</h2>
+
+<p>
+Denison had scarcely gone to arrange for some one to watch the office that
+night, when Kennedy, having gathered up his radioscope and packed into a parcel
+a few other things from various cabinets, announced: “Walter, I must see that
+Miss Wallace, right away. Denison has already given me her address. Call a cab
+while I finish clearing up here. I don’t like the looks of this thing, even if
+Haughton does neglect it.”
+</p>
+
+<p>
+We found Miss Wallace at a modest boarding-house in an old but still
+respectable part of the city. She was a very pretty girl, of the slender type,
+rather a business woman than one given much to amusement. She had been ill and
+was still ill. That was evident from the solicitous way in which the motherly
+landlady scrutinized two strange callers.
+</p>
+
+<p>
+Kennedy presented a card from Denison, and she came down to the parlor to see
+us.
+</p>
+
+<p>
+“Miss Wallace,” began Kennedy, “I know it is almost cruel to trouble you when
+you are not feeling like office work, but since the robbery of the safe at
+Pittsburgh, there have been threats of a robbery of the New York office.”
+</p>
+
+<p>
+She started involuntarily, and it was evident, I thought, that she was in a
+very high-strung state.
+</p>
+
+<p>
+“Oh,” she cried, “why, the loss means ruin to Mr. Denison!”
+</p>
+
+<p>
+There were genuine tears in her eyes as she said it.
+</p>
+
+<p>
+“I thought you would be willing to aid us,” pursued Kennedy sympathetically.
+“Now, for one thing, I want to be perfectly sure just how much radium the
+Corporation owns, or rather owned before the first robbery.”
+</p>
+
+<p>
+“The books will show it,” she said simply.
+</p>
+
+<p>
+“They will?” commented Kennedy. “Then if you will explain to me briefly just
+the system you used in keeping account of it, perhaps I need not trouble you
+any more.”
+</p>
+
+<p>
+“I’ll go down there with you,” she answered bravely. “I’m better to-day,
+anyhow, I think.”
+</p>
+
+<p>
+She had risen, but it was evident that she was not as strong as she wanted us
+to think.
+</p>
+
+<p>
+“The least I can do is to make it as easy as possible by going in a car,”
+remarked Kennedy, following her into the hall where there was a telephone.
+</p>
+
+<p>
+The hallway was perfectly dark, yet as she preceded us I could see that the
+diamond pin which held her collar in the back sparkled as if a lighted candle
+had been brought near it. I had noticed in the parlor that she wore a handsome
+tortoiseshell comb set with what I thought were other brilliants, but when I
+looked I saw now that there was not the same sparkle to the comb which held her
+dark hair in a soft mass. I noticed these little things at the time, not
+because I thought they had any importance, but merely by chance, wondering at
+the sparkle of the one diamond which had caught my eye.
+</p>
+
+<p>
+“What do you make of her?” I asked as Kennedy finished telephoning.
+</p>
+
+<p>
+“A very charming and capable girl,” he answered noncommittally.
+</p>
+
+<p>
+“Did you notice how that diamond in her neck sparkled?” I asked quickly.
+</p>
+
+<p>
+He nodded. Evidently it had attracted his attention, too.
+</p>
+
+<p>
+“What makes it?” I pursued.
+</p>
+
+<p>
+“Well, you know radium rays will make a diamond fluoresce in the dark.”
+</p>
+
+<p>
+“Yes,” I objected, “but how about those in the comb?”
+</p>
+
+<p>
+“Paste, probably,” he answered tersely, as we heard her foot on the landing.
+“The rays won’t affect paste.”
+</p>
+
+<p>
+It was indeed a shame to take advantage of Miss Wallace’s loyalty to Denison,
+but she was so game about it that I knew only the utmost necessity on Kennedy’s
+part would have prompted him to do it. She had a key to the office so that it
+was not necessary to wait for Denison, if indeed we could have found him.
+</p>
+
+<p>
+Together she and Kennedy went over the records. It seemed that there were in
+the safe twenty-five platinum tubes of one hundred milligrams each, and that
+there had been twelve of the same amount at Pittsburgh. Little as it seemed in
+weight it represented a fabulous fortune.
+</p>
+
+<p>
+“You have not the combination?” inquired Kennedy.
+</p>
+
+<p>
+“No. Only Mr. Denison has that. What are you going to do to protect the safe
+to-night?” she asked.
+</p>
+
+<p>
+“Nothing especially,” evaded Kennedy.
+</p>
+
+<p>
+“Nothing?” she repeated in amazement.
+</p>
+
+<p>
+“I have another plan,” he said, watching her intently. “Miss Wallace, it was
+too much to ask you to come down here. You are ill.”
+</p>
+
+<p>
+She was indeed quite pale, as if the excitement had been an overexertion.
+</p>
+
+<p>
+“No, indeed,” she persisted. Then, feeling her own weakness, she moved toward
+the door of Denison’s office where there was a leather couch. “Let me rest here
+a moment. I do feel queer. I—”
+</p>
+
+<p>
+She would have fallen if he had not sprung forward and caught her as she sank
+to the floor, overcome by the exertion.
+</p>
+
+<p>
+Together we carried her in to the couch, and as we did so the comb from her
+hair clattered to the floor.
+</p>
+
+<p>
+Craig threw open the window, and bathed her face with water until there was a
+faint flutter of the eyelids.
+</p>
+
+<p>
+“Walter,” he said, as she began to revive, “I leave her to you. Keep her quiet
+for a few moments. She has unintentionally given me just the opportunity I
+want.”
+</p>
+
+<p>
+While she was yet hovering between consciousness and unconsciousness on the
+couch, he had unwrapped the package which he had brought with him. For a moment
+he held the comb which she had dropped near the radioscope. With a low
+exclamation of surprise he shoved it into his pocket.
+</p>
+
+<p>
+Then from the package he drew a heavy piece of apparatus which looked as if it
+might be the motor part of an electric fan, only in place of the fan he fitted
+a long, slim, vicious-looking steel bit. A flexible wire attached the thing to
+the electric light circuit and I knew that it was an electric drill. With his
+coat off he tugged at the little radium safe until he had moved it out, then
+dropped on his knees behind it and switched the current on in the electric
+drill.
+</p>
+
+<p>
+It was a tedious process to drill through the steel of the outer casing of the
+safe and it was getting late. I shut the door to the office so that Miss
+Wallace could not see.
+</p>
+
+<p>
+At last by the cessation of the low hum of the boring, I knew that he had
+struck the inner lead lining. Quietly I opened the door and stepped out. He was
+injecting something from an hermetically sealed lead tube into the opening he
+had made and allowing it to run between the two linings of lead and steel. Then
+using the tube itself he sealed the opening he had made and dabbed a little
+black over it.
+</p>
+
+<p>
+Quickly he shoved the safe back, then around it concealed several small coils
+with wires also concealed and leading out through a window to a court.
+</p>
+
+<p>
+“We’ll catch the fellow this time,” he remarked as he worked. “If you ever have
+any idea, Walter, of going into the burglary business, it would be well to
+ascertain if the safes have any of these little selenium cells as suggested by
+my friend, Mr. Hammer, the inventor. For by them an alarm can be given miles
+away the moment an intruder’s bull’s-eye falls on a hidden cell sensitive to
+light.”
+</p>
+
+<p>
+While I was delegated to take Miss Wallace home, Kennedy made arrangements with
+a small shopkeeper on the ground floor of a building that backed up on the
+court for the use of his back room that night, and had already set up a bell
+actuated by a system of relays which the weak current from the selenium cells
+could operate.
+</p>
+
+<p>
+It was not until nearly midnight that he was ready to leave the laboratory
+again, where he had been busily engaged in studying the tortoiseshell comb
+which Miss Wallace in her weakness had forgotten.
+</p>
+
+<p>
+The little shopkeeper let us in sleepily and Kennedy deposited a large round
+package on a chair in the back of the shop, as well as a long piece of rubber
+tubing. Nothing had happened so far.
+</p>
+
+<p>
+As we waited the shopkeeper, now wide awake and not at all unconvinced that we
+were bent on some criminal operation, hung around. Kennedy did not seem to
+care. He drew from his pocket a little shiny brass instrument in a lead case,
+which looked like an abbreviated microscope.
+</p>
+
+<p>
+“Look through it,” he said, handing it to me.
+</p>
+
+<p>
+I looked and could see thousands of minute sparks.
+</p>
+
+<p>
+“What is it?” I asked.
+</p>
+
+<p>
+“A spinthariscope. In that it is possible to watch the bombardment of the
+countless little corpuscles thrown off by radium, as they strike on the zinc
+blende crystal which forms the base. When radium was originally discovered, the
+interest was merely in its curious properties, its power to emit invisible rays
+which penetrated solid substances and rendered things fluorescent, of expending
+energy without apparent loss.
+</p>
+
+<p>
+“Then came the discovery,” he went on, “of its curative powers. But the first
+results were not convincing. Still, now that we know the reasons why radium may
+be dangerous and how to protect ourselves against them we know we possess one
+of the most wonderful of curative agencies.”
+</p>
+
+<p>
+I was thinking rather of the dangers than of the beneficence of radium just
+now, but Kennedy continued.
+</p>
+
+<p>
+“It has cured many malignant growths that seemed hopeless, brought back
+destroyed cells, exercised good effects in diseases of the liver and intestines
+and even the baffling diseases of the arteries. The reason why harm, at first,
+as well as good came, is now understood. Radium emits, as I told you before,
+three kinds of rays, the alpha, beta, and gamma rays, each with different
+properties. The emanation is another matter. It does not concern us in this
+case, as you will see.”
+</p>
+
+<p>
+Fascinated as I was by the mystery of the case, I began to see that he was
+gradually arriving at an explanation which had baffled everyone else.
+</p>
+
+<p>
+“Now, the alpha rays are the shortest,” he launched forth, “in length let us
+say one inch. They exert a very destructive effect on healthy tissue. That is
+the cause of injury. They are stopped by glass, aluminum and other metals, and
+are really particles charged with positive electricity. The beta rays come
+next, say, about an inch and a half. They stimulate cell growth. Therefore they
+are dangerous in cancer, though good in other ways. They can be stopped by
+lead, and are really particles charged with negative electricity. The gamma
+rays are the longest, perhaps three inches long, and it is these rays which
+effect cures, for they check the abnormal and stimulate the normal cells. They
+penetrate lead. Lead seems to filter them out from the other rays. And at three
+inches the other rays don’t reach, anyhow. The gamma rays are not charged with
+electricity at all, apparently.”
+</p>
+
+<p>
+He had brought a little magnet near the spinthariscope. I looked into it.
+</p>
+
+<p>
+“A magnet,” he explained, “shows the difference between the alpha, beta, and
+gamma rays. You see those weak and wobbly rays that seem to fall to one side?
+Those are the alpha rays. They have a strong action, though, on tissues and
+cells. Those falling in the other direction are the beta rays. The gamma rays
+seem to flow straight.”
+</p>
+
+<p>
+“Then it is the alpha rays with which we are concerned mostly now?” I queried,
+looking up.
+</p>
+
+<p>
+“Exactly. That is why, when radium is unprotected or insufficiently protected
+and comes too near, it is destructive of healthy cells, produces burns, sores,
+which are most difficult to heal. It is with the explanation of such sores that
+we must deal.”
+</p>
+
+<p>
+It was growing late. We had waited patiently now for some time. Kennedy had
+evidently reserved this explanation, knowing we should have to wait. Still
+nothing happened.
+</p>
+
+<p>
+Added to the mystery of the violet-colored glass plate was now that of the
+luminescent diamond. I was about to ask Kennedy point-blank what he thought of
+them, when suddenly the little bell before us began to buzz feebly under the
+influence of a current.
+</p>
+
+<p>
+I gave a start. The faithful little selenium cell burglar alarm had done the
+trick. I knew that selenium was a good conductor of electricity in the light,
+poor in the dark. Some one had, therefore, flashed a light on one of the cells
+in the Corporation office. It was the moment for which Kennedy had prepared.
+</p>
+
+<p>
+Seizing the round package and the tubing, he dashed out on the street and
+around the corner. He tried the door opening into the Radium Corporation
+hallway. It was closed, but unlocked. As it yielded and we stumbled in, up the
+old worn wooden stairs of the building, I knew that there must be some one
+there.
+</p>
+
+<p>
+A terrific, penetrating, almost stunning odor seemed to permeate the air even
+in the hall.
+</p>
+
+<p>
+Kennedy paused at the door of the office, tried it, found it unlocked, but did
+not open it.
+</p>
+
+<p>
+“That smell is ethyldichloracetate,” he explained. “That was what I injected
+into the air cushion of that safe between the two linings. I suppose my man
+here used an electric drill. He might have used thermit or an oxyacetylene
+blowpipe for all I would care. These fumes would discourage a cracksman from
+‘soup’ to nuts,” he laughed, thoroughly pleased at the protection modern
+science had enabled him to devise.
+</p>
+
+<p>
+As we stood an instant by the door, I realized what had happened. We had
+captured our man. He was asphyxiated!
+</p>
+
+<p>
+Yet how were we to get to him? Would Craig leave him in there, perhaps to die?
+To go in ourselves meant to share his fate, whatever might be the effect of the
+drug.
+</p>
+
+<p>
+Kennedy had torn the wrapping off the package. From it he drew a huge globe
+with bulging windows of glass in the front and several curious arrangements on
+it at other points. To it he fitted the rubber tubing and a little pump. Then
+he placed the globe over his head, like a diver’s helmet, and fastened some
+air-tight rubber arrangement about his neck and shoulders.
+</p>
+
+<p>
+“Pump, Walter!” he shouted. “This is an oxygen helmet such as is used in
+entering mines filled with deadly gases.”
+</p>
+
+<p>
+Without another word he was gone into the blackness of the noxious stifle which
+filled the Radium Corporation office since the cracksman had struck the
+unexpected pocket of rapidly evaporating stuff.
+</p>
+
+<p>
+I pumped furiously.
+</p>
+
+<p>
+Inside I could hear him blundering around. What was he doing?
+</p>
+
+<p>
+He was coming back slowly. Was he, too, overcome?
+</p>
+
+<p>
+As he emerged into the darkness of the hallway where I myself was almost
+sickened, I saw that he was dragging with him a limp form.
+</p>
+
+<p>
+A rush of outside air from the street door seemed to clear things a little.
+Kennedy tore off the oxygen helmet and dropped down on his knees beside the
+figure, working its arms in the most approved manner of resuscitation.
+</p>
+
+<p>
+“I think we can do it without calling on the pulmotor,” he panted. “Walter, the
+fumes have cleared away enough now in the outside office. Open a window—and
+keep that street door open, too.”
+</p>
+
+<p>
+I did so, found the switch and turned on the lights.
+</p>
+
+<p>
+It was Denison himself!
+</p>
+
+<p>
+For many minutes Kennedy worked over him. I bent down, loosened his collar and
+shirt, and looked eagerly at his chest for the tell-tale marks of the radium
+which I felt sure must be there. There was not even a discoloration.
+</p>
+
+<p>
+Not a word was said, as Kennedy brought the stupefied little man around.
+</p>
+
+<p>
+Denison, pale, shaken, was leaning back now in a big office chair, gasping and
+holding his head.
+</p>
+
+<p>
+Kennedy, before him, reached down into his pocket and handed him the
+spinthariscope.
+</p>
+
+<p>
+“You see that?” he demanded.
+</p>
+
+<p>
+Denison looked through the eyepiece.
+</p>
+
+<p>
+“Wh—where did you get so much of it?” he asked, a queer look on his face.
+</p>
+
+<p>
+“I got that bit of radium from the base of the collar button of Hartley
+Haughton,” replied Kennedy quietly, “a collar button which some one intimate
+with him had substituted for his own, bringing that deadly radium with only the
+minutest protection of a thin strip of metal close to the back of his neck,
+near the spinal cord and the medulla oblongata which controls blood pressure.
+That collar button was worse than the poisoned rings of the Borgias. And there
+is more radium in the pretty gift of a tortoiseshell comb with its paste
+diamonds which Miss Wallace wore in her hair. Only a fraction of an inch, not
+enough to cut off the deadly alpha rays, protected the wearers of those
+articles.”
+</p>
+
+<p>
+He paused a moment, while surging through my mind came one after another the
+explanations of the hitherto inexplicable. Denison seemed almost to cringe in
+the chair, weak already from the fumes.
+</p>
+
+<p>
+“Besides,” went on Kennedy remorselessly, “when I went in there to drag you
+out, I saw the safe open. I looked. There was nothing in those pretty platinum
+tubes, as I suspected. European trust—bah! All the cheap devices of a faker
+with a confederate in London to send a cablegram—and another in New York to
+send a threatening letter.”
+</p>
+
+<p>
+Kennedy extended an accusing forefinger at the man cowering before him.
+</p>
+
+<p>
+“This is nothing but a get-rich-quick scheme, Denison. There never was a
+milligram of radium in the Poor Little Rich Valley, not a milligram here in all
+the carefully kept reports of Miss Wallace—except what was bought outside by
+the Corporation with the money it collected from its dupes. Haughton has been
+fleeced. Miss Wallace, blinded by her loyalty to you—you will always find such
+a faithful girl in such schemes as yours—has been fooled.
+</p>
+
+<p>
+“And how did you repay it? What was cleverer, you said to yourself, than to
+seem to be robbed of what you never had, to blame it on a bitter rival who
+never existed? Then to make assurance doubly sure, you planned to disable,
+perhaps get rid of the come-on whom you had trimmed, and the faithful girl
+whose eyes you had blinded to your gigantic swindle.
+</p>
+
+<p>
+“Denison,” concluded Kennedy, as the man drew back, his very face convicting
+him, “Denison, you are the radium robber—robber in another sense!”

+THE DEAD LINE</h2>
+
+<p>
+Maiden Lane, no less than Wall Street, was deeply interested in the radium
+case. In fact, it seemed that one case in this section of the city led to
+another.
+</p>
+
+<p>
+Naturally, the <i>Star</i> and the other papers made much of the capture of
+Denison. Still, I was not prepared for the host of Maiden Lane cases that
+followed. Many of them were essentially trivial. But one proved to be of
+extreme importance.
+</p>
+
+<p>
+“Professor Kennedy, I have just heard of your radium case, and I—I feel that I
+can—trust you.”
+</p>
+
+<p>
+There was a note of appeal in the hesitating voice of the tall, heavily veiled
+woman whose card had been sent up to us with a nervous “Urgent” written across
+its face.
+</p>
+
+<p>
+It was very early in the morning, but our visitor was evidently completely
+unnerved by some news which she had just received and which had sent her
+posting to see Craig.
+</p>
+
+<p>
+Kennedy met her gaze directly with a look that arrested her involuntary effort
+to avoid it again. She must have read in his eyes more than in his words that
+she might trust him.
+</p>
+
+<p>
+“I—I have a confession to make,” she faltered.
+</p>
+
+<p>
+“Please sit down, Mrs. Moulton,” he said simply. “It is my business to receive
+confidences—and to keep them.”
+</p>
+
+<p>
+She sank into, rather than sat down in, the deep leather rocker beside his
+desk, and now for the first time raised her veil.
+</p>
+
+<p>
+Antoinette Moulton was indeed stunning, an exquisite creature with a wonderful
+charm of slender youth, brightness of eye and brunette radiance.
+</p>
+
+<p>
+I knew that she had been on the musical comedy stage and had had a rapid rise
+to a star part before her marriage to Lynn Moulton, the wealthy lawyer, almost
+twice her age. I knew also that she had given up the stage, apparently without
+a regret. Yet there was something strange about the air of secrecy of her
+visit. Was there a hint in it of a disagreement between the Moultons, I
+wondered, as I waited while Kennedy reassured her.
+</p>
+
+<p>
+Her distress was so unconcealed that Craig, for the moment, laid aside his
+ordinary inquisitorial manner. “Tell me just as much or just as little as you
+choose, Mrs. Moulton,” he added tactfully. “I will do my best.”
+</p>
+
+<p>
+A look almost of gratitude crossed her face.
+</p>
+
+<p>
+“When we were married,” she began again, “my husband gave me a beautiful
+diamond necklace. Oh, it must have been worth a hundred thousand dollars
+easily. It was splendid. Everyone has heard of it. You know, Lynn—er—Mr.
+Moulton, has always been an enthusiastic collector of jewels.”
+</p>
+
+<p>
+She paused again and Kennedy nodded reassuringly. I knew the thought in his
+mind. Moulton had collected one gem that was incomparable with all the hundred
+thousand dollar necklaces in existence.
+</p>
+
+<p>
+“Several months ago.” she went on rapidly, still avoiding his eyes and forcing
+the words from her reluctant lips, “I—oh, I needed money—terribly.”
+</p>
+
+<p>
+She had risen and faced him, pressing her daintily gloved hands together in a
+little tremble of emotion which was none the less genuine because she had
+studied the art of emotion.
+</p>
+
+<p>
+“I took the necklace to a jeweler, Herman Schloss, of Maiden Lane, a man with
+whom my husband had often had dealings and whom I thought I could trust. Under
+a promise of secrecy he loaned me fifty thousand dollars on it and had an exact
+replica in paste made by one of his best workmen. This morning, just now, Mr.
+Schloss telephoned me that his safe had been robbed last night. My necklace is
+gone!”
+</p>
+
+<p>
+She threw out her hands in a wildly appealing gesture.
+</p>
+
+<p>
+“And if Lynn finds that the necklace in our wall safe is of paste—as he will
+find, for he is an expert in diamonds—oh—what shall I do? Can’t you—can’t you
+find my necklace?”
+</p>
+
+<p>
+Kennedy was following her now eagerly. “You were blackmailed out of the money?”
+he queried casually, masking his question.
+</p>
+
+<p>
+There was a sudden, impulsive drooping of her mouth, an evasion and keen
+wariness in her eyes. “I can’t see that that has anything to do with the
+robbery,” she answered in a low voice.
+</p>
+
+<p>
+“I beg your pardon,” corrected Kennedy quickly. “Perhaps not. I’m sorry. Force
+of habit, I suppose. You don’t know anything more about the robbery?”
+</p>
+
+<p>
+“N—no, only that it seems impossible that it could have happened in a place
+that has the wonderful burglar alarm protection that Mr. Schloss described to
+me.”
+</p>
+
+<p>
+“You know him pretty well?”
+</p>
+
+<p>
+“Only through this transaction,” she replied hastily. “I wish to heaven I had
+never heard of him.”
+</p>
+
+<p>
+The telephone rang insistently.
+</p>
+
+<p>
+“Mrs. Moulton,” said Kennedy, as he returned the receiver to the hook, “it may
+interest you to know that the burglar alarm company has just called me up about
+the same case. If I had need of an added incentive, which I hope you will
+believe I have not, that might furnish it. I will do my best,” he repeated.
+</p>
+
+<p>
+“Thank you—a thousand times,” she cried fervently, and, had I been Craig, I
+think I should have needed no more thanks than the look she gave him as he
+accompanied her to the door of our apartment.
+</p>
+
+<p>
+It was still early and the eager crowds were pushing their way to business
+through the narrow network of downtown streets as Kennedy and I entered a large
+office on lower Broadway in the heart of the jewelry trade and financial
+district.
+</p>
+
+<p>
+“One of the most amazing robberies that has ever been attempted has been
+reported to us this morning,” announced James McLear, manager of the Hale
+Electric Protection, adding with a look half of anxiety, half of skepticism,
+“that is, if it is true.”
+</p>
+
+<p>
+McLear was a stocky man, of powerful build and voice and a general appearance
+of having been once well connected with the city detective force before an
+attractive offer had taken him into this position of great responsibility.
+</p>
+
+<p>
+“Herman Schloss, one of the best known of Maiden Lane jewelers,” he continued,
+“has been robbed of goods worth two or three hundred thousand dollars—and in
+spite of every modern protection. So that you will get it clearly, let me show
+you what we do here.”
+</p>
+
+<p>
+He ushered us into a large room, on the walls of which were hundreds of little
+indicators. From the front they looked like rows of little square compartments,
+tier on tier, about the size of ordinary post office boxes. Closer examination
+showed that each was equipped with a delicate needle arranged to oscillate
+backward and forward upon the very minutest interference with the electric
+current. Under the boxes, each of which bore a number, was a series of drops
+and buzzers numbered to correspond with the boxes.
+</p>
+
+<p>
+“In nearly every office in Maiden Lane where gems and valuable jewelry are
+stored,” explained McLear, “this electrical system of ours is installed. When
+the safes are closed at night and the doors swung together, a current of
+electricity is constantly shooting around the safes, conducted by cleverly
+concealed wires. These wires are picked up by a cable system which finds its
+way to this central office. Once here, the wires are safeguarded in such manner
+that foreign currents from other wires or from lightning cannot disturb the
+system.”
+</p>
+
+<p>
+We looked with intense interest at this huge electrical pulse that felt every
+change over so vast and rich an area.
+</p>
+
+<p>
+“Passing a big dividing board,” he went on, “they are distributed and connected
+each in its place to the delicate tangent galvanometers and sensitive
+indicators you see in this room. These instantly announce the most minute
+change in the working of the current, and each office has a distinct separate
+metallic circuit. Why, even a hole as small as a lead pencil in anything
+protected would sound the alarm here.”
+</p>
+
+<p>
+Kennedy nodded appreciatively.
+</p>
+
+<p>
+“You see,” continued McLear, glad to be able to talk to one who followed him so
+closely, “it is another evidence of science finding for us greater security in
+the use of a tiny electric wire than in massive walls of steel and intricate
+lock devices. But here is a case in which, it seems, every known protection has
+failed. We can’t afford to pass that by. If we have fallen down we want to know
+how, as well as to catch the burglar.”
+</p>
+
+<p>
+“How are the signals given?” I asked.
+</p>
+
+<p>
+“Well, when the day’s business is over, for instance, Schloss would swing the
+heavy safe doors together and over them place the doors of a wooden cabinet.
+That signals an alarm to us here. We answer it and if the proper signal is
+returned, all right. After that no one can tamper with the safe later in the
+night without sounding an alarm that would bring a quick investigation.”
+</p>
+
+<p>
+“But suppose that it became necessary to open the safe before the next morning.
+Might not some trusted employee return to the office, open it, give the proper
+signals and loot the safe?”
+</p>
+
+<p>
+“No indeed,” he answered confidently. “The very moment anyone touches the
+cabinet, the alarm is sounded. Even if the proper code signal is returned, it
+is not sufficient. A couple of our trusted men from the central office hustle
+around there anyhow and they don’t leave until they are satisfied that
+everything is right. We have the authorized signatures on hand of those who are
+supposed to open the safe and a duplicate of one of them must be given or there
+is an arrest.”
+</p>
+
+<p>
+McLear considered for a moment.
+</p>
+
+<p>
+“For instance, Schloss, like all the rest, was assigned a box in which was
+deposited a sealed envelope containing a key to the office and his own
+signature, in this case, since he alone knew the combination. Now, when an
+alarm is sounded, as it was last night, and the key removed to gain entrance to
+the office, a record is made and the key has to be sealed up again by Schloss.
+A report is also submitted showing when the signals are received and anything
+else that is worth recording. Last night our men found nothing wrong,
+apparently. But this morning we learn of the robbery.”
+</p>
+
+<p>
+“The point is, then,” ruminated Kennedy, “what happened in the interval between
+the ringing of the alarm and the arrival of the special officers? I think I’ll
+drop around and look Schloss’ place over,” he added quietly, evidently eager to
+begin at the actual scene of the crime.
+</p>
+
+<p>
+On the door of the office to which McLear took us was one of those small blue
+plates which chance visitors to Maiden Lane must have seen often. To the
+initiated—be he crook or jeweler—this simple sign means that the merchant is a
+member of the Jewelers’ Security Alliance, enough in itself, it would seem, to
+make the boldest burglar hesitate. For it is the motto of this organization to
+“get” the thief at any cost and at any time. Still, it had not deterred the
+burglar in this instance.
+</p>
+
+<p>
+“I know people are going to think it is a fake burglary,” exclaimed Schloss, a
+stout, prosperous-looking gem broker, as we introduced ourselves. “But over two
+hundred thousands dollars’ worth of stones are gone,” he half groaned. “Think
+of it, man,” he added, “one of the greatest robberies since the Dead Line was
+established. And if they can get away with it, why, no one down here is
+protected any more. Half a billion dollars in jewels in Maiden Lane and John
+Street are easy prey for the cracksmen!”
+</p>
+
+<p>
+Staggering though the loss must have been to him, he had apparently recovered
+from the first shock of the discovery and had begun the fight to get back what
+had been lost.
+</p>
+
+<p>
+It was, as McLear had intimated, a most amazing burglary, too. The door of
+Schloss’ safe was open when Kennedy and I arrived and found the excited jeweler
+nervously pacing the office. Surrounding the safe, I noticed a wooden framework
+constructed in such a way as to be a part of the decorative scheme of the
+office.
+</p>
+
+<p>
+Schloss banged the heavy doors shut.
+</p>
+
+<p>
+“There, that’s just how it was—shut as tight as a drum. There was absolutely no
+mark of anyone tampering with the combination lock. And yet the safe was
+looted!”
+</p>
+
+<p>
+“How did you discover it?” asked Craig. “I presume you carry burglary
+insurance?”
+</p>
+
+<p>
+Schloss looked up quickly. “That’s what I expected as a first question. No, I
+carried very little insurance. You see, I thought the safe, one of those new
+chrome steel affairs, was about impregnable. I never lost a moment’s sleep over
+it; didn’t think it possible for anyone to get into it. For, as you see, it is
+completely wired by the Hale Electric Protection—that wooden framework about
+it. No one could touch that when it was set without jangling a bell at the
+central office which would send men scurrying here to protect the place.”
+</p>
+
+<p>
+“But they must have got past it,” suggested Kennedy.
+</p>
+
+<p>
+“Yes—they must have. At least this morning I received the regular Hale report.
+It said that their wires registered last night as though some one was tampering
+with the safe. But by the time they got around, in less than five minutes,
+there was no one here, nothing seemed to be disturbed. So they set it down to
+induction or electrolysis, or something the matter with the wires. I got the
+report the first thing when I arrived here with my assistant, Muller.”
+</p>
+
+<p>
+Kennedy was on his knees, going over the safe with a fine brush and some
+powder, looking now and then through a small magnifying glass.
+</p>
+
+<p>
+“Not a finger print,” he muttered. “The cracksman must have worn gloves. But
+how did he get in? There isn’t a mark of ‘soup’ having been used to blow it up,
+nor of a ‘can-opener’ to rip it open, if that were possible, nor of an electric
+or any other kind of drill.”
+</p>
+
+<p>
+“I’ve read of those fellows who burn their way in,” said Schloss.
+</p>
+
+<p>
+“But there is no hole,” objected Kennedy, “not a trace of the use of thermit to
+burn the way in or of the oxyacetylene blowpipe to cut a piece out. Most
+extraordinary,” he murmured.
+</p>
+
+<p>
+“You see,” shrugged Schloss, “everyone will say it must have been opened by one
+who knew the combination. But I am the only one. I have never written it down
+or told anyone, not even Muller. You understand what I am up against?”
+</p>
+
+<p>
+“There’s the touch system,” I suggested. “You remember, Craig, the old fellow
+who used to file his finger tips to the quick until they were so sensitive that
+he could actually feel when he had turned the combination to the right plunger?
+Might not that explain the lack of finger prints also?” I added eagerly.
+</p>
+
+<p>
+“Nothing like that in this case, Walter,” objected Craig positively. “This
+fellow wore gloves, all right. No, this safe has been opened and looted by no
+ordinarily known method. It’s the most amazing case I ever saw in that
+respect—almost as if we had a cracksman in the fourth dimension to whom the
+inside of a closed cube is as accessible as is the inside of a plane square to
+us three dimensional creatures. It is almost incomprehensible.”
+</p>
+
+<p>
+I fancied I saw Schloss’ face brighten as Kennedy took this view. So far,
+evidently, he had run across only skepticism.
+</p>
+
+<p>
+“The stones were unset?” resumed Craig.
+</p>
+
+<p>
+“Mostly. Not all.”
+</p>
+
+<p>
+“You would recognize some of them if you saw them?”
+</p>
+
+<p>
+“Yes indeed. Some could be changed only by re-cutting. Even some of those that
+were set were of odd cut and size—some from a diamond necklace which belonged
+to a—”
+</p>
+
+<p>
+There was something peculiar in both his tone and manner as he cut short the
+words.
+</p>
+
+<p>
+“To whom?” asked Kennedy casually.
+</p>
+
+<p>
+“Oh, once to a well-known woman in society,” he said carefully. “It is mine,
+though, now—at least it was mine. I should prefer to mention no names. I will
+give a description of the stones.”
+</p>
+
+<p>
+“Mrs. Lynn Moulton, for instance?” suggested Craig quietly.
+</p>
+
+<p>
+Schloss jumped almost as if a burglar alarm had sounded under his very ears.
+“How did you know? Yes—but it was a secret. I made a large loan on it, and the
+time has expired.”
+</p>
+
+<p>
+“Why did she need money so badly?” asked Kennedy.
+</p>
+
+<p>
+“How should I know?” demanded Schloss.
+</p>
+
+<p>
+Here was a deepening mystery, not to be elucidated by continuing this line of
+inquiry with Schloss, it seemed.

+THE PASTE REPLICA</h2>
+
+<p>
+Carefully Craig was going over the office. Outside of the safe, there had
+apparently been nothing of value. The rest of the office was not even wired,
+and it seemed to have been Schloss’ idea that the few thousands of burglary
+insurance amply protected him against such loss. As for the safe, its own
+strength and the careful wiring might well have been considered quite
+sufficient under any hitherto to-be-foreseen circumstances.
+</p>
+
+<p>
+A glass door, around the bend of a partition, opened from the hallway into the
+office and had apparently been designed with the object of making visible the
+safe so that anyone passing might see whether an intruder was tampering with
+it.
+</p>
+
+<p>
+Kennedy had examined the door, perhaps in the expectation of finding finger
+prints there, and was passing on to other things, when a change in his position
+caused his eye to catch a large oval smudge on the glass, which was visible
+when the light struck it at the right angle. Quickly he dusted it over with the
+powder, and brought out the detail more clearly. As I examined it, while Craig
+made preparations to cut out the glass to preserve it, it seemed to contain a
+number of minute points and several more or less broken parallel lines. The
+edges gradually trailed off into an indistinct faintness.
+</p>
+
+<p>
+Business, naturally, was at a standstill, and as we were working near the door,
+we could see that the news of Schloss’ strange robbery had leaked out and was
+spreading rapidly. Scores of acquaintances in the trade stopped at the door to
+inquire about the rumor.
+</p>
+
+<p>
+To each, it seemed that Morris Muller, the working jeweler employed by Schloss,
+repeated the same story.
+</p>
+
+<p>
+“Oh,” he said, “it is a big loss—yes—but big as it is, it will not break Mr.
+Schloss. And,” he would add with the tradesman’s idea of humor, “I guess he has
+enough to play a game of poker—eh?”
+</p>
+
+<p>
+“Poker?” asked Kennedy smiling. “Is he much of a player?”
+</p>
+
+<p>
+“Yes. Nearly every night with his friends he plays.”
+</p>
+
+<p>
+Kennedy made a mental note of it. Evidently Schloss trusted Muller implicitly.
+He seemed like a partner, rather than an employee, even though he had not been
+entrusted with the secret combination.
+</p>
+
+<p>
+Outside, we ran into city detective Lieutenant Winters, the officer who was
+stationed at the Maiden Lane post, guarding that famous section of the Dead
+Line established by the immortal Byrnes at Fulton Street, below which no crook
+was supposed to dare even to be seen. Winters had been detailed on the case.
+</p>
+
+<p>
+“You have seen the safe in there?” asked Kennedy, as he was leaving to carry on
+his investigation elsewhere.
+</p>
+
+<p>
+Winters seemed to be quite as skeptical as Schloss had intimated the public
+would be. “Yes,” he replied, “there’s been an epidemic of robbery with the dull
+times—people who want to collect their burglary insurance, I guess.”
+</p>
+
+<p>
+“But,” objected Kennedy, “Schloss carried so little.”
+</p>
+
+<p>
+“Well, there was the Hale Protection. How about that?”
+</p>
+
+<p>
+Craig looked up quickly, unruffled by the patronizing air of the professional
+toward the amateur detective.
+</p>
+
+<p>
+“What is your theory?” he asked. “Do you think he robbed himself?”
+</p>
+
+<p>
+Winters shrugged his shoulders. “I’ve been interested in Schloss for some
+time,” he said enigmatically. “He has had some pretty swell customers. I’ll
+keep you wised up, if anything happens,” he added in a burst of graciousness,
+walking off.
+</p>
+
+<p>
+On the way to the subway, we paused again to see McLear.
+</p>
+
+<p>
+“Well,” he asked, “what do you think of it, now?”
+</p>
+
+<p>
+“All most extraordinary,” ruminated Craig. “And the queerest feature of all is
+that the chief loss consists of a diamond necklace that belonged once to Mrs.
+Antoinette Moulton.”
+</p>
+
+<p>
+“Mrs. Lynn Moulton?” repeated McLear.
+</p>
+
+<p>
+“The same,” assured Kennedy.
+</p>
+
+<p>
+McLear appeared somewhat puzzled. “Her husband is one of our old subscribers,”
+he pursued. “He is a lawyer on Wall Street and quite a gem collector. Last
+night his safe was tampered with, but this morning he reports no loss. Not half
+an hour ago he had us on the wire congratulating us on scaring off the
+burglars, if there had been any.”
+</p>
+
+<p>
+“What is your opinion,” I asked. “Is there a gang operating?”
+</p>
+
+<p>
+“My belief is,” he answered, reminiscently of his days on the detective force,
+“that none of the loot will be recovered until they start to ‘fence’ it. That
+would be my lay—to look for the fence. Why, think of all the big robberies that
+have been pulled off lately. Remember,” he went on, “the spoils of a burglary
+consist generally of precious stones. They are not currency. They must be
+turned into currency—or what’s the use of robbery?
+</p>
+
+<p>
+“But merely to offer them for sale at an ordinary jeweler’s would be
+suspicious. Even pawnbrokers are on the watch. You see what I am driving at? I
+think there is a man or a group of men whose business it is to pay cash for
+stolen property and who have ways of returning gems into the regular trade
+channels. In all these robberies we get a glimpse of as dark and mysterious a
+criminal as has ever been recorded. He may be—anybody. About his legitimacy, I
+believe, no question has ever been raised. And, I tell you, his arrest is going
+to create a greater sensation than even the remarkable series of robberies that
+he has planned or made possible. The question is, to my mind, who is this
+fence?”
+</p>
+
+<p>
+McLear’s telephone rang and he handed the instrument to Craig.
+</p>
+
+<p>
+“Yes, this is Professor Kennedy,” answered Craig. “Oh, too bad you’ve had to
+try all over to get me. I’ve been going from one place to another gathering
+clues and have made good progress, considering I’ve hardly started. Why—what’s
+the matter? Really?”
+</p>
+
+<p>
+An interval followed, during which McLear left to answer a personal call on
+another wire.
+</p>
+
+<p>
+As Kennedy hung up the receiver, his face wore a peculiar look. “It was Mrs.
+Moulton,” he blurted out. “She thinks that her husband has found out that the
+necklace is paste.”
+</p>
+
+<p>
+“How?” I asked.
+</p>
+
+<p>
+“The paste replica is gone from her wall safe in the Deluxe.”
+</p>
+
+<p>
+I turned, startled at the information. Even Kennedy himself was perplexed at
+the sudden succession of events. I had nothing to say.
+</p>
+
+<p>
+Evidently, however, his rule was when in doubt play a trump, for, twenty
+minutes later found us in the office of Lynn Moulton, the famous corporation
+lawyer, in Wall Street.
+</p>
+
+<p>
+Moulton was a handsome man of past fifty with a youthful face against his iron
+gray hair and mustache, well dressed, genial, a man who seemed keenly in love
+with the good things of life.
+</p>
+
+<p>
+“It is rumored,” began Kennedy, “that an attempt was made on your safe here at
+the office last night.”
+</p>
+
+<p>
+“Yes,” he admitted, taking off his glasses and polishing them carefully. “I
+suppose there is no need of concealment, especially as I hear that a somewhat
+similar attempt was made on the safe of my friend Herman Schloss in Maiden
+Lane.”
+</p>
+
+<p>
+“You lost nothing?”
+</p>
+
+<p>
+Moulton put his glasses on and looked Kennedy in the face frankly.
+</p>
+
+<p>
+“Nothing, fortunately,” he said, then went on slowly. “You see, in my later
+years, I have been something of a collector of precious stones myself. I don’t
+wear them, but I have always taken the keenest pleasure in owning them and when
+I was married it gave me a great deal more pleasure to have them set in rings,
+pendants, tiaras, necklaces, and other forms for my wife.”
+</p>
+
+<p>
+He had risen, with the air of a busy man who had given the subject all the
+consideration he could afford and whose work proceeded almost by schedule.
+“This morning I found my safe tampered with, but, as I said, fortunately
+something must have scared off the burglars.”
+</p>
+
+<p>
+He bowed us out politely. What was the explanation, I wondered. It seemed, on
+the face of things, that Antoinette Moulton feared her husband. Did he know
+something else already, and did she know he knew? To all appearances he took it
+very calmly, if he did know. Perhaps that was what she feared, his very
+calmness.
+</p>
+
+<p>
+“I must see Mrs. Moulton again,” remarked Kennedy, as we left.
+</p>
+
+<p>
+The Moultons lived, we found, in one of the largest suites of a new apartment
+hotel, the Deluxe, and in spite of the fact that our arrival had been announced
+some minutes before we saw Mrs. Moulton, it was evident that she had been
+crying hysterically over the loss of the paste jewels and what it implied.
+</p>
+
+<p>
+“I missed it this morning, after my return from seeing you,” she replied in
+answer to Craig’s inquiry, then added, wide-eyed with alarm, “What shall I do?
+He must have opened the wall safe and found the replica. I don’t dare ask him
+point-blank.”
+</p>
+
+<p>
+“Are you sure he did it?” asked Kennedy, more, I felt, for its moral effect on
+her than through any doubt in his own mind.
+</p>
+
+<p>
+“Not sure. But then the wall safe shows no marks, and the replica is gone.”
+</p>
+
+<p>
+“Might I see your jewel case?” he asked.
+</p>
+
+<p>
+“Surely. I’ll get it. The wall safe is in Lynn’s room. I shall probably have to
+fuss a long time with the combination.”
+</p>
+
+<p>
+In fact she could not have been very familiar with it for it took several
+minutes before she returned. Meanwhile, Kennedy, who had been drumming absently
+on the arms of his chair, suddenly rose and walked quietly over to a scrap
+basket that stood beside an escritoire. It had evidently just been emptied, for
+the rooms must have been cleaned several hours before. He bent down over it and
+picked up two scraps of paper adhering to the wicker work. The rest had
+evidently been thrown away.
+</p>
+
+<p>
+I bent over to read them. One was:
+</p>
+
+<p class="poem">
+—rest Nettie—<br/>
+—dying to see—
+</p>
+
+<p>
+The other read:
+</p>
+
+<p class="poem">
+—cherche to-d<br/>
+—love and ma<br/>
+—rman.
+</p>
+
+<p>
+What did it mean? Hastily, I could fill in “Dearest Nettie,” and “I am dying to
+see you.” Kennedy added, “The Recherche to-day,” that being the name of a new
+apartment uptown, as well as “love and many kisses.” But “—rman”—what did that
+mean? Could it be Herman—Herman Schloss?
+</p>
+
+<p>
+She was returning and we resumed our seats quickly.
+</p>
+
+<p>
+Kennedy took the jewel case from her and examined it carefully. There was not a
+mark on it.
+</p>
+
+<p>
+“Mrs. Moulton,” he said slowly, rising and handing it back to her, “have you
+told me all?”
+</p>
+
+<p>
+“Why—yes,” she answered.
+</p>
+
+<p>
+Kennedy shook his head gravely.
+</p>
+
+<p>
+“I’m afraid not. You must tell me everything.”
+</p>
+
+<p>
+“No—no,” she cried vehemently, “there is nothing more.”
+</p>
+
+<p>
+We left and outside the Deluxe he paused, looked about, caught sight of a
+taxicab and hailed it.
+</p>
+
+<p>
+“Where?” asked the driver.
+</p>
+
+<p>
+“Across the street,” he said, “and wait. Put the window in back of you down so
+I can talk. I’ll tell you where to go presently. Now, Walter, sit back as far
+as you can. This may seem like an underhand thing to do, but we’ve got to get
+what that woman won’t tell us or give up the case.”
+</p>
+
+<p>
+Perhaps half an hour we waited, still puzzling over the scraps of paper.
+Suddenly I felt a nudge from Kennedy. Antoinette Moulton was standing in the
+doorway across the street. Evidently she preferred not to ride in her own car,
+for a moment later she entered a taxicab.
+</p>
+
+<p>
+“Follow that black cab,” said Kennedy to our driver.
+</p>
+
+<p>
+Sure enough, it stopped in front of the Recherche Apartments and Mrs. Moulton
+stepped out and almost ran in.
+</p>
+
+<p>
+We waited a moment, then Kennedy followed. The elevator that had taken her up
+had just returned to the ground floor.
+</p>
+
+<p>
+“The same floor again,” remarked Kennedy, jauntily stepping in and nodding
+familiarly to the elevator boy.
+</p>
+
+<p>
+Then he paused suddenly, looked at his watch, fixed his gaze thoughtfully on me
+an instant, and exclaimed. “By George—no. I can’t go up yet. I clean forgot
+that engagement at the hotel. One moment, son. Let us out. We’ll be back
+again.”
+</p>
+
+<p>
+Considerably mystified, I followed him to the sidewalk.
+</p>
+
+<p>
+“You’re entitled to an explanation,” he laughed catching my bewildered look as
+he opened the cab door. “I didn’t want to go up now while she is there, but I
+wanted to get on good terms with that boy. We’ll wait until she comes down,
+then go up.”
+</p>
+
+<p>
+“Where?” I asked.
+</p>
+
+<p>
+“That’s what I am going through all this elaborate preparation to find out. I
+have no more idea than you have.”
+</p>
+
+<p>
+It could not have been more than twenty minutes later when Mrs. Moulton emerged
+rather hurriedly, and drove away.
+</p>
+
+<p>
+While we had been waiting I had observed a man on the other side of the street
+who seemed unduly interested in the Recherche, too, for he had walked up and
+down the block no less than six times. Kennedy saw him, and as he made no
+effort to follow Mrs. Moulton, Kennedy did not do so either. In fact a little
+quick glance which she had given at our cab had raised a fear that she might
+have discovered that she was being followed.
+</p>
+
+<p>
+Kennedy and I paid off our cabman and sauntered into the Recherche in the most
+debonair manner we could assume.
+</p>
+
+<p>
+“Now, son, we’ll go up,” he said to the boy who, remembering us, and now not at
+all clear in his mind that he might not have seen us before that, whisked us to
+the tenth floor.
+</p>
+
+<p>
+“Let me see,” said Kennedy, “it’s number one hundred and—er——”
+</p>
+
+<p>
+“Three,” prompted the boy.
+</p>
+
+<p>
+He pressed the buzzer and a neatly dressed colored maid responded.
+</p>
+
+<p>
+“I had an appointment here with Mrs. Moulton this morning,” remarked Kennedy.
+</p>
+
+<p>
+“She has just gone,” replied the maid, off her guard.
+</p>
+
+<p>
+“And was to meet Mr. Schloss here in half an hour,” he added quickly.
+</p>
+
+<p>
+It was the maid’s turn to look surprised.
+</p>
+
+<p>
+“I didn’t think he was to be here,” she said. “He’s had some—”
+</p>
+
+<p>
+“Trouble at the office,” supplied Kennedy. “That’s what it was about. Perhaps
+he hasn’t been able to get away yet. But I had the appointment. Ah, I see a
+telephone in the hall. May I?”
+</p>
+
+<p>
+He had stepped politely in, and by dint of cleverly keeping his finger on the
+hook in the half light, he carried on a one-sided conversation with himself
+long enough to get a good chance to look about.
+</p>
+
+<p>
+There was an air of quiet and refinement about the apartment in the Recherche.
+It was darkened to give the little glowing electric bulbs in their silken
+shades a full chance to simulate right. The deep velvety carpets were noiseless
+to the foot, and the draperies, the pictures, the bronzes, all bespoke taste.
+</p>
+
+<p>
+But the chief objects of interest to Craig were the little square green
+baize-covered tables on one of which lay neatly stacked a pile of gilt-edged
+cards and a mahogany box full of ivory chips of red, white and blue.
+</p>
+
+<p>
+It was none of the old-time gambling places, like Danfield’s, with its steel
+door which Craig had once cut through with an oxyacetylene blowpipe in order to
+rescue a young spendthrift from himself.
+</p>
+
+<p>
+Kennedy seemed perfectly well satisfied merely with a cursory view of the
+place, as he hung up the receiver and thanked the maid politely for allowing
+him to use it.
+</p>
+
+<p>
+“This is up-to-date gambling in cleaned-up New York,” he remarked as we waited
+for the elevator to return for us. “And the worst of it all is that it gets the
+women as well as the men. Once they are caught in the net, they are the most
+powerful lure to men that the gamblers have yet devised.”
+</p>
+
+<p>
+We rode down in silence, and as we went down the steps to the street, I noticed
+the man whom we had seen watching the place, lurking down at the lower corner.
+Kennedy quickened his pace and came up behind him.
+</p>
+
+<p>
+“Why, Winters!” exclaimed Craig. “You here?”
+</p>
+
+<p>
+“I might say the same to you,” grinned the detective not displeased evidently
+that our trail had crossed his. “I suppose you are looking for Schloss, too.
+He’s up in the Recherche a great deal, playing poker. I understand he owns an
+interest in the game up there.”
+</p>
+
+<p>
+Kennedy nodded, but said nothing.
+</p>
+
+<p>
+“I just saw one of the cappers for the place go out before you went in.”
+</p>
+
+<p>
+“Capper?” repeated Kennedy surprised. “Antoinette Moulton a steerer for a
+gambling joint? What can a rich society woman have to do with a place like that
+or a man like Schloss?”
+</p>
+
+<p>
+Winters smiled sardonically. “Society ladies to-day often get into scrapes of
+which their husbands know nothing,” he remarked. “You didn’t know before that
+Antoinette Moulton, like many of her friends in the smart set, was a
+gambler—and loser—did you?”
+</p>
+
+<p>
+Craig shook his head. He had more of human than scientific interest in a case
+of a woman of her caliber gone wrong.
+</p>
+
+<p>
+“But you must have read of the famous Moulton diamonds?”
+</p>
+
+<p>
+“Yes,” said Craig, blankly, as if it were all news to him.
+</p>
+
+<p>
+“Schloss has them—or at least had them. The jewels she wore at the opera this
+winter were paste, I understand.”
+</p>
+
+<p>
+“Does Moulton play?” he asked.
+</p>
+
+<p>
+“I think so—but not here, naturally. In a way, I suppose, it is his fault. They
+all do it. The example of one drives on another.”
+</p>
+
+<p>
+Instantly there flashed over my mind a host of possibilities. Perhaps, after
+all, Winters had been right. Schloss had taken this way to make sure of the
+jewels so that she could not redeem them. Suddenly another explanation crowded
+that out. Had Mrs. Moulton robbed the safe herself, or hired some one else to
+do it for her, and had that person gone back on her?
+</p>
+
+<p>
+Then a horrid possibility occurred to me. Whatever Antoinette Moulton may have
+been and done, some one must have her in his power. What a situation for the
+woman! My sympathy went out to her in her supreme struggle. Even if it had been
+a real robbery, Schloss might easily recover from it. But for her every event
+spelled ruin and seemed only to be bringing that ruin closer.
+</p>
+
+<p>
+We left Winters, still watching on the trail of Schloss, and went on uptown to
+the laboratory.

+THE BURGLAR’S MICROPHONE</h2>
+
+<p>
+That night I was sitting, brooding over the case, while Craig was studying a
+photograph which he made of the smudge on the glass door down at Schloss’. He
+paused in his scrutiny of the print to answer the telephone.
+</p>
+
+<p>
+“Something has happened to Schloss,” he exclaimed seizing his hat and coat.
+“Winters has been watching him. He didn’t go to the Recherche. Winters wants me
+to meet him at a place several blocks below it Come on. He wouldn’t say over
+the wire what it was. Hurry.”
+</p>
+
+<p>
+We met Winters in less than ten minutes at the address he had given, a bachelor
+apartment in the neighborhood of the Recherche.
+</p>
+
+<p>
+“Schloss kept rooms here,” explained Winters, hurrying us quickly upstairs. “I
+wanted you to see before anyone else.”
+</p>
+
+<p>
+As we entered the large and luxuriously furnished living room of the jeweler’s
+suite, a gruesome sight greeted us.
+</p>
+
+<p>
+There lay Schloss on the floor, face down, in a horribly contorted position. In
+one hand, clenched under him partly, the torn sleeve of a woman’s dress was
+grasped convulsively. The room bore unmistakable traces of a violent struggle,
+but except for the hideous object on the floor was vacant.
+</p>
+
+<p>
+Kennedy bent down over him. Schloss was dead. In a corner, by the door, stood a
+pile of grips, stacked up, packed, and undisturbed.
+</p>
+
+<p>
+Winters who had been studying the room while we got our bearings picked up a
+queer-looking revolver from the floor. As he held it up I could see that along
+the top of the barrel was a long cylinder with a ratchet or catch at the butt
+end. He turned it over and over carefully.
+</p>
+
+<p>
+“By George,” he muttered, “it has been fired off.”
+</p>
+
+<p>
+Kennedy glanced more minutely at the body. There was not a mark on it. I stared
+about vacantly at the place where Winters had picked the thing up.
+</p>
+
+<p>
+“Look,” I cried, my eye catching a little hole in the baseboard of the woodwork
+near it.
+</p>
+
+<p>
+“It must have fallen and exploded on the floor,” remarked Kennedy. “Let me see
+it, Winters.”
+</p>
+
+<p>
+Craig held it at arm’s length and pulled the catch. Instead of an explosion,
+there came a cone of light from the top of the gun. As Kennedy moved it over
+the wall, I saw in the center of the circle of light a dark spot.
+</p>
+
+<p>
+“A new invention,” Craig explained. “All you need to do is to move it so that
+little dark spot falls directly on an object. Pull the trigger—the bullet
+strikes the dark spot. Even a nervous and unskilled marksman becomes a good
+shot in the dark. He can even shoot from behind the protection of something—and
+hit accurately.”
+</p>
+
+<p>
+It was too much for me. I could only stand and watch Kennedy as he deftly bent
+over Schloss again and placed a piece of chemically prepared paper flat on the
+forehead of the dead man.
+</p>
+
+<p>
+When he withdrew it, I could see that it bore marks of the lines on his head.
+Without a word, Kennedy drew from his pocket a print of the photograph of the
+smudge on Schloss’ door.
+</p>
+
+<p>
+“It is possible,” he said, half to himself, “to identify a person by means of
+the arrangement of the sweat glands or pores. Poroscopy, Dr. Edmond Locard,
+director of the Police Laboratory at Lyons, calls it. The shape, arrangement,
+number per square centimeter, all vary in different individuals. Besides, here
+we have added the lines of the forehead.”
+</p>
+
+<p>
+He was studying the two impressions intensely. When he looked up from his
+examination, his face wore a peculiar expression.
+</p>
+
+<p>
+“This is not the head which was placed so close to the glass of the door of
+Schloss’ office, peering through, on the night of the robbery, in order to see
+before picking the lock whether the office was empty and everything ready for
+the hasty attack on the safe.”
+</p>
+
+<p>
+“That disposes of my theory that Schloss robbed himself,” remarked Winters
+reluctantly. “But the struggle here, the sleeve of the dress, the pistol—could
+he have been shot?”
+</p>
+
+<p>
+“No, I think not,” considered Kennedy. “It looks to me more like a case of
+apoplexy.”
+</p>
+
+<p>
+“What shall we do?” asked Winters. “Far from clearing anything up, this
+complicates it.”
+</p>
+
+<p>
+“Where’s Muller?” asked Kennedy. “Does he know? Perhaps he can shed some light
+on it.”
+</p>
+
+<p>
+The clang of an ambulance bell outside told that the aid summoned by Winters
+had arrived.
+</p>
+
+<p>
+We left the body in charge of the surgeon and of a policeman who arrived about
+the same time, and followed Winters.
+</p>
+
+<p>
+Muller lived in a cheap boarding house in a shabbily respectable street
+downtown, and without announcing ourselves we climbed the stairs to his room.
+He looked up surprised but not disconcerted as we entered.
+</p>
+
+<p>
+“What’s the matter?” he asked.
+</p>
+
+<p>
+“Muller,” shot out Winters, “we have just found Mr. Schloss dead!”
+</p>
+
+<p>
+“D-dead!” he stammered.
+</p>
+
+<p>
+The man seemed speechless with horror.
+</p>
+
+<p>
+“Yes, and with his grips packed as if to run away.”
+</p>
+
+<p>
+Muller looked dazedly from one of us to the other, but shut up like a clam.
+</p>
+
+<p>
+“I think you had better come along with us as a material witness,” burst out
+Winters roughly.
+</p>
+
+<p>
+Kennedy said nothing, leaving that sort of third degree work to the detective.
+But he was not idle, as Winters tried to extract more than the monosyllables,
+“I don’t know,” in answer to every inquiry of Muller about his employer’s life
+and business.
+</p>
+
+<p>
+A low exclamation from Craig attracted my attention from Winters. In a corner
+he had discovered a small box and had opened it. Inside was a dry battery and a
+most peculiar instrument, something like a little flat telephone transmitter
+yet attached by wires to earpieces that fitted over the head after the manner
+of those of a wireless detector.
+</p>
+
+<p>
+“What’s this?” asked Kennedy, dangling it before Muller.
+</p>
+
+<p>
+He looked at it phlegmatically. “A deaf instrument I have been working on,”
+replied the jeweler. “My hearing is getting poor.”
+</p>
+
+<p>
+Kennedy looked hastily from the instrument to the man.
+</p>
+
+<p>
+“I think I’ll take it along with us,” he said quietly.
+</p>
+
+<p>
+Winters, true to his instincts, had been searching Muller in the meantime.
+Besides the various assortment that a man carries in his pockets usually,
+including pens, pencils, notebooks, a watch, a handkerchief, a bunch of keys,
+one of which was large enough to open a castle, there was a bunch of blank and
+unissued pawn-tickets bearing the name, “Stein’s One Per Cent. a Month Loans,”
+and an address on the Bowery.
+</p>
+
+<p>
+Was Muller the “fence” we were seeking, or only a tool for the “fence” higher
+up? Who was this Stein?
+</p>
+
+<p>
+What it all meant I could only guess. It was a far cry from the wealth of
+Diamond Lane to a dingy Bowery pawnshop, even though pawnbroking at one per
+cent. a month—and more, on the side—pays. I knew, too, that diamonds are
+hoarded on the East Side as nowhere else in the world, outside of India. It was
+no uncommon thing, I had heard, for a pawnbroker whose shop seemed dirty and
+greasy to the casual visitor to have stored away in his vault gems running into
+the hundreds of thousands of dollars.
+</p>
+
+<p>
+“Mrs. Moulton must know of this,” remarked Kennedy. “Winters, you and Jameson
+bring Muller along. I am going up to the Deluxe.”
+</p>
+
+<p>
+I must say that I was surprised at finding Mrs. Moulton there. Outside the
+suite Winters and I waited with the unresisting Muller, while Kennedy entered.
+But through the door which he left ajar I could hear what passed.
+</p>
+
+<p>
+“Mrs. Moulton,” he began, “something terrible has happened—”
+</p>
+
+<p>
+He broke off, and I gathered that her pale face and agitated manner told him
+that she knew already.
+</p>
+
+<p>
+“Where is Mr. Moulton?” he went on, changing his question.
+</p>
+
+<p>
+“Mr. Moulton is at his office,” she answered tremulously. “He telephoned while
+I was out that he had to work to-night. Oh, Mr. Kennedy—he knows—he knows. I
+know it. He has avoided me ever since I missed the replica from-”
+</p>
+
+<p>
+“Sh!” cautioned Craig. He had risen and gone to the door.
+</p>
+
+<p>
+“Winters,” he whispered, “I want you to go down to Lynn Moulton’s office.
+Meanwhile Jameson can take care of Muller. I am going over to that place of
+Stein’s presently. Bring Moulton up there. You will wait here, Walter, for the
+present,” he nodded.
+</p>
+
+<p>
+He returned to the room where I could hear her crying softly.
+</p>
+
+<p>
+“Now, Mrs. Moulton,” he said gently, “I’m afraid I must trouble you to go with
+me. I am going over to a pawnbroker’s on the Bowery.”
+</p>
+
+<p>
+“The Bowery?” she repeated, with a genuinely surprised shudder. “Oh, no, Mr.
+Kennedy. Don’t ask me to go anywhere to-night. I am—I am in no condition to go
+anywhere—to do anything—I—”
+</p>
+
+<p>
+“But you must,” said Kennedy in a low voice.
+</p>
+
+<p>
+“I can’t. Oh—have mercy on me. I am terribly upset. You—”
+</p>
+
+<p>
+“It is your duty to go, Mrs. Moulton,” he repeated.
+</p>
+
+<p>
+“I don’t understand.” she murmured. “A pawnbroker’s?”
+</p>
+
+<p>
+“Come,” urged Kennedy, not harshly but firmly, then, as she held back, added,
+playing a trump card, “We must work quickly. In his hands we found the
+fragments of a torn dress. When the police—”
+</p>
+
+<p>
+She uttered a shriek. A glance had told her, if she had deceived herself
+before, that Kennedy knew her secret.
+</p>
+
+<p>
+Antoinette Moulton was standing before him, talking rapidly.
+</p>
+
+<p>
+“Some one has told Lynn. I know it. There is nothing now that I can conceal. If
+you had come half an hour later you would not have found me. He had written to
+Mr. Schloss, threatening him that if he did not leave the country he would
+shoot him at sight. Mr. Schloss showed me the letter.
+</p>
+
+<p>
+“It had come to this. I must either elope with Schloss, or lose his aid. The
+thought of either was unendurable. I hated him—yet was dependent on him.
+</p>
+
+<p>
+“To-night I met him, in his empty apartment, alone. I knew that he had what was
+left of his money with him, that everything was packed up. I went prepared. I
+would not elope. My plan was no less than to make him pay the balance on the
+necklace that he had lost—or to murder him.
+</p>
+
+<p>
+“I carried a new pistol in my muff, one which Lynn had just bought. I don’t
+know how I did it. I was desperate.
+</p>
+
+<p>
+“He told me he loved me, that Lynn did not, never had—that Lynn had married me
+only to show off his wealth and diamonds, to give him a social! position—that I
+was merely a—a piece of property—a dummy.
+</p>
+
+<p>
+“He tried to kiss me. It was revolting. I struggled away from him.
+</p>
+
+<p>
+“And in the struggle, the revolver fell from my muff and exploded on the floor.
+</p>
+
+<p>
+“At once he was aflame with suspicion.
+</p>
+
+<p>
+“‘So—it’s murder you want!’ he shouted. ‘Well, murder it shall be!’
+</p>
+
+<p>
+“I saw death in his eye as he seized my arm. I was defenseless now. The old
+passion came over him. Before he killed—he—would have his way with me.
+</p>
+
+<p>
+“I screamed. With a wild effort I twisted away from him.
+</p>
+
+<p>
+“He raised his hand to strike me, I saw his eyes, glassy. Then he sank
+back—fell to the floor—dead of apoplexy—dead of his furious emotions.
+</p>
+
+<p>
+“I fled.
+</p>
+
+<p>
+“And now you have found me.”
+</p>
+
+<p>
+She had turned, hastily, to leave the room. Kennedy blocked the door.
+</p>
+
+<p>
+“Mrs. Moulton,” he said firmly, “listen to me. What was the first question you
+asked me? ‘Can I trust you?’ And I told you you could. This is no time for—for
+suicide.” He shot the word out bluntly. “All may not be lost. I have sent for
+your husband. Muller is outside.”
+</p>
+
+<p>
+“Muller?” she cried. “He made the replica.”
+</p>
+
+<p>
+“Very well. I am going to clear this thing up. Come. You <i>must</i>.”
+</p>
+
+<p>
+It was all confused to me, the dash in a car to the little pawnbroker’s on the
+first floor of a five-story tenement, the quick entry into the place by one of
+Muller’s keys.
+</p>
+
+<p>
+Over the safe in back was a framework like that which had covered Schloss’
+safe. Kennedy tore it away, regardless of the alarm which it must have sounded.
+In a moment he was down before it on his knees.
+</p>
+
+<p>
+“This is how Schloss’ safe was opened so quickly,” he muttered, working
+feverishly. “Here is some of their own medicine.”
+</p>
+
+<p>
+He had placed the peculiar telephone-like transmitter close to the combination
+lock and was turning the combination rapidly.
+</p>
+
+<p>
+Suddenly he rose, gave the bolts a twist, and the ponderous doors swung open.
+</p>
+
+<p>
+“What is it?” I asked eagerly.
+</p>
+
+<p>
+“A burglar’s microphone,” he answered, hastily looking over the contents of the
+safe. “The microphone is now used by burglars for picking combination locks.
+When you turn the lock, a slight sound is made when the proper number comes
+opposite the working point. It can be heard sometimes by a sensitive ear,
+although it is imperceptible to most persons. But by using a microphone it is
+an easy matter to hear the sounds which allow of opening the lock.”
+</p>
+
+<p>
+He had taken a yellow chamois bag out of the safe and opened it.
+</p>
+
+<p>
+Inside sparkled the famous Moulton diamonds. He held them up—in all their
+wicked brilliancy. No one spoke.
+</p>
+
+<p>
+Then he took another yellow bag, more dirty and worn than the first. As he
+opened it, Mrs. Moulton could restrain herself no longer.
+</p>
+
+<p>
+“The replica!” she cried. “The replica!”
+</p>
+
+<p>
+Without a word, Craig handed the real necklace to her. Then he slipped the
+paste jewels into the newer of the bags and restored both it and the empty one
+to their places, banged shut the door of the safe, and replaced the wooden
+screen.
+</p>
+
+<p>
+“Quick!” he said to her, “you have still a minute to get away.
+Hurry—anywhere—away—only away!”
+</p>
+
+<p>
+The look of gratitude that came over her face, as she understood the full
+meaning of it was such as I had never seen before.
+</p>
+
+<p>
+“Quick!” he repeated.
+</p>
+
+<p>
+It was too late.
+</p>
+
+<p>
+“For God’s sake, Kennedy,” shouted a voice at the street door, “what are you
+doing here?”
+</p>
+
+<p>
+It was McLear himself. He had come with the Hale patrol, on his mettle now to
+take care of the epidemic of robberies.
+</p>
+
+<p>
+Before Craig could reply a cab drew up with a rush at the curb and two men,
+half fighting, half cursing, catapulted themselves into the shop.
+</p>
+
+<p>
+They were Winters and Moulton.
+</p>
+
+<p>
+Without a word, taking advantage of the first shock of surprise, Kennedy had
+clapped a piece of chemical paper on the foreheads of Mrs. Moulton, then of
+Moulton, and on Muller’s. Oblivious to the rest of us, he studied the
+impressions in the full light of the counter.
+</p>
+
+<p>
+Moulton was facing his wife with a scornful curl of the lip.
+</p>
+
+<p>
+“I’ve been told of the paste replica—and I wrote Schloss that I’d shoot him
+down like the dog he is, you—you traitress,” he hissed.
+</p>
+
+<p>
+She drew herself up scornfully.
+</p>
+
+<p>
+“And I have been told why you married me—to show off your wicked jewels and
+help you in your—”
+</p>
+
+<p>
+“You lie!” he cried fiercely. “Muller—some one—open this safe—whosever it is.
+If what I have been told is true, there is in it one new bag containing the
+necklace. It was stolen from Schloss to whom you sold <i>my</i> jewels. The
+other old bag, stolen from me, contains the paste replica you had made to
+deceive me.”
+</p>
+
+<p>
+It was all so confused that I do not know how it happened. I think it was
+Muller who opened the safe.
+</p>
+
+<p>
+“There is the new yellow bag,” cried Moulton, “from Schloss’ own safe. Open
+it.”
+</p>
+
+<p>
+McLear had taken it. He did so. There sparkled not the real gems, but the
+replica.
+</p>
+
+<p>
+“The devil!” Moulton exclaimed, breaking from Winters and seizing the old bag.
+</p>
+
+<p>
+He tore it open and—it was empty.
+</p>
+
+<p>
+“One moment,” interrupted Kennedy, looking up quietly from the counter. “Seal
+that safe again, McLear. In it are the Schloss jewels and the products of half
+a dozen other robberies which the dupe Muller—or Stein, as you please—pulled
+off, some as a blind to conceal the real criminal. You may have shown him how
+to leave no finger prints, but you yourself have left what is just as good—your
+own forehead print. McLear—you were right. There’s your criminal—Lynn Moulton,
+professional fence, the brains of the thing.”

+<h2><a name="chap19"></a>CHAPTER XIX<br/>
+THE GERM LETTER</h2>
+
+<p>
+Lynn Moulton made no fight and Kennedy did not pursue the case, for, with the
+rescue of Antoinette Moulton, his interest ceased.
+</p>
+
+<p>
+Blackmail takes various forms, and the Moulton affair was only one phase of it.
+It was not long before we had to meet a much stranger attempt.
+</p>
+
+<p>
+“Read the letter, Professor Kennedy. Then I will tell you the sequel.”
+</p>
+
+<p>
+Mrs. Hunter Blake lay back in the cushions of her invalid chair in the sun
+parlor of the great Blake mansion on Riverside Drive, facing the Hudson with
+its continuous reel of maritime life framed against the green-hilled background
+of the Jersey shore.
+</p>
+
+<p>
+Her nurse, Miss Dora Sears, gently smoothed out the pillows and adjusted them
+so that the invalid could more easily watch us. Mrs. Blake, wealthy, known as a
+philanthropist, was not an old woman, but had been for years a great sufferer
+from rheumatism.
+</p>
+
+<p>
+I watched Miss Sears eagerly. Full-bosomed, fine of face and figure, she was
+something more than a nurse; she was a companion. She had bright, sparkling
+black eyes and an expression about her well-cut mouth which made one want to
+laugh with her. It seemed to say that the world was a huge joke and she invited
+you to enjoy the joke with her.
+</p>
+
+<p>
+Kennedy took the letter which Miss Sears proffered him, and as he did so I
+could not help noticing her full, plump forearm on which gleamed a handsome
+plain gold bracelet. He spread the letter out on a dainty wicker table in such
+a way that we both could see it.
+</p>
+
+<p>
+We had been summoned over the telephone to the Blake mansion by Reginald Blake,
+Mrs. Blake’s eldest son. Reginald had been very reticent over the reason, but
+had seemed very anxious and insistent that Kennedy should come immediately.
+</p>
+
+<p>
+Craig read quickly and I followed him, fascinated by the letter from its very
+opening paragraph.
+</p>
+
+<p>
+“Dear Madam,” it began. “Having received my diploma as doctor of medicine and
+bacteriology at Heidelberg in 1909, I came to the United States to study a most
+serious disease which is prevalent in several of the western mountain states.”
+</p>
+
+<p>
+So far, I reflected, it looked like an ordinary appeal for aid. The next words,
+however, were queer: “I have four hundred persons of wealth on my list. Your
+name was—”
+</p>
+
+<p>
+Kennedy turned the page. On the next leaf of the letter sheet was pasted a
+strip of gelatine. The first page had adhered slightly to the gelatine.
+</p>
+
+<p>
+“Chosen by fate,” went on the sentence ominously.
+</p>
+
+<p>
+“By opening this letter,” I read, “you have liberated millions of the virulent
+bacteria of this disease. Without a doubt you are infected by this time, for no
+human body is impervious to them, and up to the present only one in one hundred
+has fully recovered after going through all its stages.”
+</p>
+
+<p>
+I gasped. The gelatine had evidently been arranged so that when the two sheets
+were pulled apart, the germs would be thrown into the air about the person
+opening the letter. It was a very ingenious device.
+</p>
+
+<p>
+The letter continued, “I am happy to say, however, that I have a prophylactic
+which will destroy any number of these germs if used up to the ninth day. It is
+necessary only that you should place five thousand dollars in an envelope and
+leave it for me to be called for at the desk of the Prince Henry Hotel. When
+the messenger delivers the money to me, the prophylactic will be sent
+immediately.
+</p>
+
+<p>
+“First of all, take a match and burn this letter to avoid spreading the
+disease. Then change your clothes and burn the old ones. Enclosed you will find
+in a germ-proof envelope an exact copy of this letter. The room should then be
+thoroughly fumigated. Do not come into close contact with anyone near and dear
+to you until you have used the prophylactic. Tell no one. In case you do, the
+prophylactic will not be sent under any circumstances. Very truly yours,
+D<small>R</small>. H<small>ANS</small> H<small>OPF</small>.”
+</p>
+
+<p>
+“Blackmail!” exclaimed Kennedy, looking intently again at the gelatine on the
+second page, as I involuntarily backed away and held my breath.
+</p>
+
+<p>
+“Yes, I know,” responded Mrs. Blake anxiously, “but is it true?”
+</p>
+
+<p>
+There could be no doubt from the tone of her voice that she more than half
+believed that it was true.
+</p>
+
+<p>
+“I cannot say—yet,” replied Craig, still cautiously scanning the apparently
+innocent piece of gelatine on the original letter which Mrs. Blake had not
+destroyed. “I shall have to keep it and examine it.”
+</p>
+
+<p>
+On the gelatine I could see a dark mass which evidently was supposed to contain
+the germs.
+</p>
+
+<p>
+“I opened the letter here in this room,” she went on. “At first I thought
+nothing of it. But this morning, when Buster, my prize Pekinese, who had been
+with me, sitting on my lap at the time, and closer to the letter even than I
+was, when Buster was taken suddenly ill, I—well, I began to worry.”
+</p>
+
+<p>
+She finished with a little nervous laugh, as people will to hide their real
+feelings.
+</p>
+
+<p>
+“I should like to see the dog,” remarked Kennedy simply.
+</p>
+
+<p>
+“Miss Sears,” asked her mistress, “will you get Buster, please?”
+</p>
+
+<p>
+The nurse left the room. No longer was there the laughing look on her face.
+This was serious business.
+</p>
+
+<p>
+A few minutes later she reappeared, carrying gingerly a small dog basket. Mrs.
+Blake lifted the lid. Inside was a beautiful little “Peke,” and it was easy to
+see that Buster was indeed ill.
+</p>
+
+<p>
+“Who is your doctor?” asked Craig, considering.
+</p>
+
+<p>
+“Dr. Rae Wilson, a very well-known woman physician.”
+</p>
+
+<p>
+Kennedy nodded recognition of the name. “What does she say?” he asked,
+observing the dog narrowly.
+</p>
+
+<p>
+“We haven’t told anyone, outside, of it yet,” replied Mrs. Blake. “In fact
+until Buster fell sick, I thought it was a hoax.”
+</p>
+
+<p>
+“You haven’t told anyone?”
+</p>
+
+<p>
+“Only Reginald and my daughter Betty. Betty is frantic—not with fear for
+herself, but with fear for me. No one can reassure her. In fact it was as much
+for her sake as anyone’s that I sent for you. Reginald has tried to trace the
+thing down himself, but has not succeeded.”
+</p>
+
+<p>
+She paused. The door opened and Reginald Blake entered. He was a young fellow,
+self confident and no doubt very efficient at the new dances, though scarcely
+fitted to rub elbows with a cold world which, outside of his own immediate
+circle, knew not the name of Blake. He stood for a moment regarding us through
+the smoke of his cigarette.
+</p>
+
+<p>
+“Tell me just what you have done,” asked Kennedy of him as his mother
+introduced him, although he had done the talking for her over the telephone.
+</p>
+
+<p>
+“Done?” he drawled. “Why, as soon as mother told me of the letter, I left an
+envelope up at the Prince Henry, as it directed.”
+</p>
+
+<p>
+“With the money?” put in Craig quickly.
+</p>
+
+<p>
+“Oh, no—just as a decoy.”
+</p>
+
+<p>
+“Yes. What happened?”
+</p>
+
+<p>
+“Well, I waited around a long time. It was far along in the day when a woman
+appeared at the desk. I had instructed the clerk to be on the watch for anyone
+who asked for mail addressed to a Dr. Hopf. The clerk slammed the register.
+That was the signal. I moved up closer.”
+</p>
+
+<p>
+“What did she look like?” asked Kennedy keenly.
+</p>
+
+<p>
+“I couldn’t see her face. But she was beautifully dressed, with a long light
+flowing linen duster, a veil that hid her features and on her hands and arms a
+long pair of motoring doeskin gloves. By George, she was a winner—in general
+looks, though. Well, something about the clerk, I suppose, must have aroused
+her suspicions. For, a moment later, she was gone in the crowd. Evidently she
+had thought of the danger and had picked out a time when the lobby would be
+full and everybody busy. But she did not leave by the front entrance through
+which she entered. I concluded that she must have left by one of the side
+street carriage doors.”
+</p>
+
+<p>
+“And she got away?”
+</p>
+
+<p>
+“Yes. I found that she asked one of the boys at the door to crank up a car
+standing at the curb. She slid into the seat, and was off in a minute.”
+</p>
+
+<p>
+Kennedy said nothing. But I knew that he was making a mighty effort to restrain
+comment on the bungling amateur detective work of the son of our client.
+</p>
+
+<p>
+Reginald saw the look on his face. “Still,” he hastened, “I got the number of
+the car. It was 200859 New York.”
+</p>
+
+<p>
+“You have looked it up?” queried Kennedy quickly.
+</p>
+
+<p>
+“I didn’t need to do it. A few minutes later Dr. Rae Wilson herself came
+out—storming like mad. Her car had been stolen at the very door of the hotel by
+this woman with the innocent aid of the hotel employees.”
+</p>
+
+<p>
+Kennedy was evidently keenly interested. The mention of the stolen car had
+apparently at once suggested an idea to him.
+</p>
+
+<p>
+“Mrs. Blake,” he said, as he rose to go, “I shall take this letter with me.
+Will you see that Buster is sent up to my laboratory immediately?”
+</p>
+
+<p>
+She nodded. It was evident that Buster was a great pet with her and that it was
+with difficulty she kept from smoothing his silky coat.
+</p>
+
+<p>
+“You—you won’t hurt Buster?” she pleaded.
+</p>
+
+<p>
+“No. Trust me. More than that, if there is any possible way of untangling this
+mystery, I shall do it.”
+</p>
+
+<p>
+Mrs. Blake looked rather than spoke her thanks. As we went downstairs,
+accompanied by Miss Sears, we could see in the music room a very interesting
+couple, chatting earnestly over the piano.
+</p>
+
+<p>
+Betty Blake, a slip of a girl in her first season, was dividing her attention
+between her visitor and the door by which we were passing.
+</p>
+
+<p>
+She rose as she heard us, leaving the young man standing alone at the piano. He
+was of an age perhaps a year or two older than Reginald Blake. It was evident
+that, whatever Miss Betty might think, he had eyes for no one else but the
+pretty debutante. He even seemed to be regarding Kennedy sullenly, as if he
+were a possible rival.
+</p>
+
+<p>
+“You—you don’t think it is serious?” whispered Betty in an undertone, scarcely
+waiting to be introduced. She had evidently known of our visit, but had been
+unable to get away to be present upstairs.
+</p>
+
+<p>
+“Really, Miss Blake,” reassured Kennedy, “I can’t say. All I can do is to
+repeat what I have already said to your mother. Keep up a good heart and trust
+me to work it out.”
+</p>
+
+<p>
+“Thank you,” she murmured, and then, impulsively extending her small hand to
+Craig, she added, “Mr. Kennedy, if there is anything I can do to help you, I
+beg that you will call on me.”
+</p>
+
+<p>
+“I shall not forget,” he answered, relinquishing the hand reluctantly. Then, as
+she thanked him, and turned again to her guest, he added in a low tone to me,
+“A remarkable girl, Walter, a girl that can be depended on.”
+</p>
+
+<p>
+We followed Miss Sears down the hall.
+</p>
+
+<p>
+“Who was that young man in the music room?” asked Kennedy, when we were out of
+earshot.
+</p>
+
+<p>
+“Duncan Baldwin,” she answered. “A friend and bosom companion of Reginald.”
+</p>
+
+<p>
+“He seems to think more of Betty than of her brother,” Craig remarked dryly.
+</p>
+
+<p>
+Miss Sears smiled. “Sometimes, we think they are secretly engaged,” she
+returned. We had almost reached the door. “By the way,” she asked anxiously,
+“do you think there are any precautions that I should take for Mrs. Blake—and
+the rest?”
+</p>
+
+<p>
+“Hardly,” answered Kennedy, after a moment’s consideration, “as long as you
+have taken none in particular already. Still, I suppose it will do no harm to
+be as antiseptic as possible.”
+</p>
+
+<p>
+“I shall try,” she promised, her face showing that she considered the affair
+now in a much more serious light than she had before our visit.
+</p>
+
+<p>
+“And keep me informed of anything that turns up,” added Kennedy handing her a
+card with the telephone number of the laboratory.
+</p>
+
+<p>
+As we left the Blake mansion, Kennedy remarked, “We must trace that car
+somehow—at least we must get someone working on that.”
+</p>
+
+<p>
+Half an hour later we were in a towering office building on Liberty Street, the
+home of various kinds of insurance. Kennedy stopped before a door which bore
+the name, “Douglas Garwood: Insurance Adjuster.”
+</p>
+
+<p>
+Briefly, Craig told the story of the stolen car, omitting the account of the
+dastardly method taken to blackmail Mrs. Blake. As he proceeded a light seemed
+to break on the face of Garwood, a heavyset man, whose very gaze was
+inquisitorial.
+</p>
+
+<p>
+“Yes, the theft has been reported to us already by Dr. Wilson herself,” he
+interrupted. “The car was insured in a company I represent.”
+</p>
+
+<p>
+“I had hoped so,” remarked Kennedy, “Do you know the woman?” he added, watching
+the insurance adjuster who had been listening intently as he told about the
+fair motor car thief.
+</p>
+
+<p>
+“Know her?” repeated Garwood emphatically. “Why, man, we have been so close to
+that woman that I feel almost intimate with her. The descriptions are those of
+a lady, well-dressed, and with a voice and manner that would carry her through
+any of the fashionable hotels, perhaps into society itself.”
+</p>
+
+<p>
+“One of a gang of blackmailers, then,” I hazarded.
+</p>
+
+<p>
+Garwood shrugged his shoulders. “Perhaps,” he acquiesced. “It is automobile
+thieving that interests me, though. Why,” he went on, rising excitedly, “the
+gangs of these thieves are getting away with half a million dollars’ worth of
+high-priced cars every year. The police seem to be powerless to stop it. We
+appeal to them, but with no result. So, now we have taken things into our own
+hands.”
+</p>
+
+<p>
+“What are you doing in this case?” asked Kennedy.
+</p>
+
+<p>
+“What the insurance companies have to do to recover stolen automobiles,”
+Garwood replied. “For, with all deference to your friend, Deputy O’Connor, it
+is the insurance companies rather than the police who get stolen cars back.”
+</p>
+
+<p>
+He had pulled out a postal card from a pigeon hole in his desk, selecting it
+from several apparently similar. We read:
+</p>
+
+<h5>$250.00 REWARD</h5>
+
+<p>
+We will pay $100.00 for car, $150.00 additional for information which will
+convict the thief. When last seen, driven by a woman, name not known, who is
+described as dark-haired, well-dressed, slight, apparently thirty years old.
+The car is a Dixon, 1912, seven-passenger, touring, No. 193,222, license No.
+200,859, New York; dark red body, mohair top, brass lamps, has no wind shield;
+rear axle brake band device has extra nut on turnbuckle not painted. Car last
+seen near Prince Henry Hotel, New York City, Friday, the 10th.
+</p>
+
+<p>
+Communicate by telegraph or telephone, after notifying nearest police
+department, with Douglas Garwood, New York City.
+</p>
+
+<p class="p2">
+“The secret of it is,” explained Garwood, as we finished reading, “that there
+are innumerable people who keep their eyes open and like to earn money easily.
+Thus we have several hundreds of amateur and enthusiastic detectives watching
+all over the city and country for any car that looks suspicious.”
+</p>
+
+<p>
+Kennedy thanked him for his courtesy, and we rose to go. “I shall be glad to
+keep you informed of anything that turns up,” he promised.

+THE ARTIFICIAL KIDNEY</h2>
+
+<p>
+In the laboratory, Kennedy quietly set to work. He began by tearing from the
+germ letter the piece of gelatine and first examining it with a pocket lens.
+Then, with a sterile platinum wire, he picked out several minute sections of
+the black spot on the gelatine and placed them in agar, blood serum, and other
+media on which they would be likely to grow.
+</p>
+
+<p>
+“I shall have to wait until to-morrow to examine them properly,” he remarked.
+“There are colonies of something there, all right, but I must have them more
+fully developed.”
+</p>
+
+<p>
+A hurried telephone call late in the day from Miss Sears told us that Mrs.
+Blake herself had begun to complain, and that Dr. Wilson had been summoned but
+had been unable to give an opinion on the nature of the malady.
+</p>
+
+<p>
+Kennedy quickly decided on making a visit to the doctor, who lived not far
+downtown from the laboratory.
+</p>
+
+<p>
+Dr. Rae Wilson proved to be a nervous little woman, inclined, I felt, to be
+dictatorial. I thought that secretly she felt a little piqued at our having
+been taken into the Blakes’ confidence before herself, and Kennedy made every
+effort to smooth that aspect over tactfully.
+</p>
+
+<p>
+“Have you any idea what it can be?” he asked finally.
+</p>
+
+<p>
+She shook her head noncommittally. “I have taken blood smears,” she answered,
+“but so far haven’t been able to discover anything. I shall have to have her
+under observation for a day or two before I can answer that. Still, as Mrs.
+Blake is so ill, I have ordered another trained nurse to relieve Miss Sears of
+the added work, a very efficient nurse, a Miss Rogers.”
+</p>
+
+<p>
+Kennedy had risen to go. “You have had no word about your car?” he asked
+casually.
+</p>
+
+<p>
+“None yet. I’m not worrying. It was insured.”
+</p>
+
+<p>
+“Who is this arch criminal, Dr. Hopf?” I mused as we retraced our steps to the
+laboratory. “Is Mrs. Blake stricken now by the same trouble that seems to have
+affected Buster?”
+</p>
+
+<p>
+“Only my examination will show,” he said. “I shall let nothing interfere with
+that now. It must be the starting point for any work that I may do in the
+case.”
+</p>
+
+<p>
+We arrived at Kennedy’s workshop of scientific crime and he immediately plunged
+into work. Looking up he caught sight of me standing helplessly idle.
+</p>
+
+<p>
+“Walter,” he remarked thoughtfully adjusting a microscope, “suppose you run
+down and see Garwood. Perhaps he has something to report. And by the way, while
+you are out, make inquiries about the Blakes, young Baldwin, Miss Sears and
+this Dr. Wilson. I have heard of her before, at least by name. Perhaps you may
+find something interesting.”
+</p>
+
+<p>
+Glad to have a chance to seem to be doing something whether it amounted to
+anything or not, I dropped in to see Garwood. So far he had nothing to report
+except the usual number of false alarms. From his office I went up to the
+<i>Star</i> where fortunately I found one of the reporters who wrote society
+notes.
+</p>
+
+<p>
+The Blakes, I found, as we already knew, to be well known and moving in the
+highest social circles. As far as known they had no particular enemies, other
+than those common to all people of great wealth. Dr. Wilson had a large
+practice, built up in recent years, and was one of the best known society
+physicians for women. Miss Sears was unknown, as far as I could determine. As
+for Duncan Baldwin, I found that he had become acquainted with Reginald Blake
+in college, that he came of no particular family and seemed to have no great
+means, although he was very popular in the best circles. In fact he had had,
+thanks to his friend, a rather meteoric rise in society, though it was reported
+that he was somewhat involved in debt as a result.
+</p>
+
+<p>
+I returned to the laboratory to find that Craig had taken out of a cabinet a
+peculiar looking arrangement. It consisted of thirty-two tubes, each about
+sixteen inches long, with S-turns, like a minute radiator. It was altogether
+not over a cubic foot in size, and enclosed in a glass cylinder. There were in
+it, perhaps, fifty feet of tubes, a perfectly-closed tubular system which I
+noticed Kennedy was keeping absolutely sterile in a germicidal solution of some
+kind.
+</p>
+
+<p>
+Inside the tubes and surrounding them was a saline solution which was kept at a
+uniform temperature by a special heating apparatus.
+</p>
+
+<p>
+Kennedy had placed the apparatus on the laboratory table and then gently took
+the little dog from his basket and laid him beside it. A few minutes later the
+poor little suffering Buster was mercifully under the influence of an
+anesthetic.
+</p>
+
+<p>
+Quickly Craig worked. First he attached the end of one of the tubes by means of
+a little cannula to the carotid artery of the dog. Then the other was attached
+to the jugular vein.
+</p>
+
+<p>
+As he released the clamp which held the artery, the little dog’s feverishly
+beating heart spurted the arterial blood from the carotid into the tubes
+holding the normal salt solution and that pressure, in turn, pumped the salt
+solution which filled the tubes into the jugular vein, thus replacing the
+arterial blood that had poured into the tubes from the other end and
+maintaining the normal hydrostatic conditions in the body circulation. The dog
+was being kept alive, although perhaps a third of his blood was out of his
+body.
+</p>
+
+<p>
+“You see,” he said at length, after we had watched the process a few minutes,
+“what I have here is in reality an artificial kidney. It is a system that has
+been devised by several doctors at Johns Hopkins.
+</p>
+
+<p>
+“If there is any toxin in the blood of this dog, the kidneys are naturally
+endeavoring to eliminate it. Perhaps it is being eliminated too slowly. In that
+case this arrangement which I have here will aid them. We call it vividiffusion
+and it depends for its action on the physical principle of osmosis, the passage
+of substances of a certain kind through a porous membrane, such as these tubes
+of celloidin.
+</p>
+
+<p>
+“Thus any substance, any poison that is dialyzable is diffused into the
+surrounding salt solution and the blood is passed back into the body, with no
+air in it, no infection, and without alteration. Clotting is prevented by the
+injection of a harmless substance derived from leeches, known as hirudin. I
+prevent the loss of anything in the blood which I want retained by placing in
+the salt solution around the tubes an amount of that substance equal to that
+held in solution by the blood. Of course that does not apply to the colloidal
+substances in the blood which would not pass by osmosis under any
+circumstances. But by such adjustments I can remove and study any desired
+substance in the blood, provided it is capable of diffusion. In fact this
+little apparatus has been found in practice to compare favorably with the
+kidneys themselves in removing even a lethal dose of poison.”
+</p>
+
+<p>
+I watched in amazement. He was actually cleaning the blood of the dog and
+putting it back again, purified, into the little body. Far from being cruel, as
+perhaps it might seem, it was in reality probably the only method by which the
+animal could be saved, and at the same time it was giving us a clue as to some
+elusive, subtle substance used in the case.
+</p>
+
+<p>
+“Indeed,” Kennedy went on reflectively, “this process can be kept up for
+several hours without injury to the dog, though I do not think that will be
+necessary to relieve the unwonted strain that has been put upon his natural
+organs. Finally, at the close of the operation, serious loss of blood is
+overcome by driving back the greater part of it into his body, closing up the
+artery and vein, and taking good care of the animal so that he will make a
+quick recovery.”
+</p>
+
+<p>
+For a long time I watched the fascinating process of seeing the life blood
+coursing through the porous tubes in the salt solution, while Kennedy gave his
+undivided attention to the success of the delicate experiment. It was late when
+I left him, still at work over Buster, and went up to our apartment to turn in,
+convinced that nothing more would happen that night.
+</p>
+
+<p>
+The next morning, with characteristic energy, Craig was at work early,
+examining the cultures he had made from the black spots on the gelatine.
+</p>
+
+<p>
+By the look of perplexity on his face, I knew that he had discovered something
+that instead of clearing the mystery up, further deepened it.
+</p>
+
+<p>
+“What do you find?” I asked anxiously.
+</p>
+
+<p>
+“Walter,” he exclaimed, laying aside the last of the slides which he had been
+staining and looking at intently through the microscope, “that stuff on the
+gelatine is entirely harmless. There was nothing in it except common mold.”
+</p>
+
+<p>
+For the moment I did not comprehend. “Mold?” I repeated.
+</p>
+
+<p>
+“Yes,” he replied, “just common, ordinary mold such as grows on the top of a
+jar of fruit or preserves when it is exposed to the air.”
+</p>
+
+<p>
+I stifled an exclamation of incredulity. It seemed impossible that the deadly
+germ note should be harmless, in view of the events that had followed its
+receipt.
+</p>
+
+<p>
+Just then the laboratory door was flung open and Reginald Blake, pale and
+excited, entered. He had every mark of having been up all night.
+</p>
+
+<p>
+“What’s the matter?” asked Craig.
+</p>
+
+<p>
+“It’s about my mother,” he blurted out. “She seems to be getting worse all the
+time. Miss Sears is alarmed, and Betty is almost ill herself with worry. Dr.
+Wilson doesn’t seem to know what it is that affects her, and neither does the
+new nurse. Can’t you <i>do</i> something?”
+</p>
+
+<p>
+There was a tone of appeal in his voice that was not like the self-sufficient
+Reginald of the day before.
+</p>
+
+<p>
+“Does there seem to be any immediate danger?” asked Kennedy.
+</p>
+
+<p>
+“Perhaps not—I can’t say,” he urged. “But she is gradually getting worse
+instead of better.”
+</p>
+
+<p>
+Kennedy thought a moment. “Has anything else happened?” he asked slowly.
+</p>
+
+<p>
+“N-no. That’s enough, isn’t it?”
+</p>
+
+<p>
+“Indeed it is,” replied Craig, trying to be reassuring. Then, recollecting
+Betty, he added, “Reginald, go back and tell your sister for me that she must
+positively make the greatest effort of her life to control herself. Tell her
+that her mother needs her—needs her well and brave. I shall be up at the house
+immediately. Do the best you can. I depend on you.”
+</p>
+
+<p>
+Kennedy’s words seemed to have a bracing effect on Reginald and a few moments
+later he left, much calmer.
+</p>
+
+<p>
+“I hope I have given him something to do which will keep him from mussing
+things up again,” remarked Kennedy, mindful of Reginald’s former excursion into
+detective work.
+</p>
+
+<p>
+Meanwhile Craig plunged furiously into his study of the substances he had
+isolated from the saline solution in which he had “washed” the blood of the
+little Pekinese.
+</p>
+
+<p>
+“There’s no use doing anything in the dark,” he explained. “Until we know what
+it is we are fighting we can’t very well fight.”
+</p>
+
+<p>
+For the moment I was overwhelmed by the impending tragedy that seemed to be
+hanging over Mrs. Blake. The more I thought of it, the more inexplicable became
+the discovery of the mold.
+</p>
+
+<p>
+“That is all very well about the mold on the gelatine strip in the letter,” I
+insisted at length. “But, Craig, there must be something wrong somewhere. Mere
+molds could not have made Buster so ill, and now the infection, or whatever it
+is, has spread to Mrs. Blake herself. What have you found out by studying
+Buster?”
+</p>
+
+<p>
+He looked up from his close scrutiny of the material in one of the test tubes
+which contained something he had recovered from the saline solution of the
+diffusion apparatus.
+</p>
+
+<p>
+I could read on his face that whatever it was, it was serious. “What is it?” I
+repeated almost breathlessly.
+</p>
+
+<p>
+“I suppose I might coin a word to describe it,” he answered slowly, measuring
+his phrases. “Perhaps it might be called hyper-amino-acidemia.”
+</p>
+
+<p>
+I puckered my eyes at the mouth-filling term Kennedy smiled. “It would mean,”
+he explained, “a great quantity of the amino-acids, non-coagulable, nitrogenous
+compounds in the blood. You know the indols, the phenols, and the amins are
+produced both by putrefactive bacteria and by the process of metabolism, the
+burning up of the tissues in the process of utilizing the energy that means
+life. But under normal circumstances, the amins are not present in the blood in
+any such quantities as I have discovered by this new method of diffusion.”
+</p>
+
+<p>
+He paused a moment, as if in deference to my inability to follow him on such an
+abstruse topic, then resumed, “As far as I am able to determine, this poison or
+toxin is an amin similar to that secreted by certain cephalopods found in the
+neighborhood of Naples. It is an aromatic amin. Smell it.”
+</p>
+
+<p>
+I bent over and inhaled the peculiar odor.
+</p>
+
+<p>
+“Those creatures,” he continued, “catch their prey by this highly active poison
+secreted by the so-called salivary glands. Even a little bit will kill a crab
+easily.”
+</p>
+
+<p>
+I was following him now with intense interest, thinking of the astuteness of a
+mind capable of thinking of such a poison.
+</p>
+
+<p>
+“Indeed, it is surprising,” he resumed thoughtfully, “how many an innocent
+substance can be changed by bacteria into a virulent poison. In fact our
+poisons and our drugs are in many instances the close relations of harmless
+compounds that represent the intermediate steps in the daily process of
+metabolism.”
+</p>
+
+<p>
+“Then,” I put in, “the toxin was produced by germs, after all?”
+</p>
+
+<p>
+“I did not say that,” he corrected. “It might have been. But I find no germs in
+the blood of Buster. Nor did Dr. Wilson find any in the blood smears which she
+took from Mrs. Blake.”
+</p>
+
+<p>
+He seemed to have thrown the whole thing back again into the limbo of the
+unexplainable, and I felt nonplussed.
+</p>
+
+<p>
+“The writer of that letter,” he went on, waving the piece of sterile platinum
+wire with which he had been transferring drops of liquid in his search for
+germs, “was a much more skillful bacteriologist than I thought, evidently. No,
+the trouble does not seem to be from germs breathed in, or from germs at all—it
+is from some kind of germ-free toxin that has been injected or otherwise
+introduced.”
+</p>
+
+<p>
+Vaguely now I began to appreciate the terrible significance of what he had
+discovered.
+</p>
+
+<p>
+“But the letter?” I persisted mechanically.
+</p>
+
+<p>
+“The writer of that was quite as shrewd a psychologist as bacteriologist,”
+pursued Craig impressively. “He calculated the moral effect of the letter, then
+of Buster’s illness, and finally of reaching Mrs. Blake herself.”
+</p>
+
+<p>
+“You think Dr. Rae Wilson knows nothing of it yet?” I queried.
+</p>
+
+<p>
+Kennedy appeared to consider his answer carefully. Then he said slowly: “Almost
+any doctor with a microscope and the faintest trace of a scientific education
+could recognize disease germs either naturally or feloniously implanted. But
+when it comes to the detection of concentrated, filtered, germ-free toxins,
+almost any scientist might be baffled. Walter,” he concluded, “this is not mere
+blackmail, although perhaps the visit of that woman to the Prince Henry—a
+desperate thing in itself, although she did get away by her quick
+thinking—perhaps that shows that these people are ready to stop at nothing. No,
+it goes deeper than blackmail.”
+</p>
+
+<p>
+I stood aghast at the discovery of this new method of scientific murder. The
+astute criminal, whoever he might be, had planned to leave not even the slender
+clue that might be afforded by disease germs. He was operating, not with
+disease itself, but with something showing the ultimate effects, perhaps, of
+disease with none of the preliminary symptoms, baffling even to the best of
+physicians.
+</p>
+
+<p>
+I scarcely knew what to say. Before I realized it, however, Craig was at last
+ready for the promised visit to Mrs. Blake. We went together, carrying Buster,
+in his basket, not recovered, to be sure, but a very different little animal
+from the dying creature that had been sent to us at the laboratory.

+<h2><a name="chap21"></a>CHAPTER XXI<br/>
+THE POISON BRACELET</h2>
+
+<p>
+We reached the Blake mansion and were promptly admitted. Miss Betty, bearing up
+bravely under Reginald’s reassurances, greeted us before we were fairly inside
+the door, though she and her brother were not able to conceal the fact that
+their mother was no better. Miss Sears was out, for an airing, and the new
+nurse, Miss Rogers, was in charge of the patient.
+</p>
+
+<p>
+“How do you feel, this morning?” inquired Kennedy as we entered the sun-parlor,
+where Mrs. Blake had first received us.
+</p>
+
+<p>
+A single glance was enough to satisfy me of the seriousness of her condition.
+She seemed to be in almost a stupor from which she roused herself only with
+difficulty. It was as if some overpowering toxin were gradually undermining her
+already weakened constitution.
+</p>
+
+<p>
+She nodded recognition, but nothing further.
+</p>
+
+<p>
+Kennedy had set the dog basket down near her wheel-chair and she caught sight
+of it.
+</p>
+
+<p>
+“Buster?” she murmured, raising her eyes. “Is—he—all right?”
+</p>
+
+<p>
+For answer, Craig simply raised the lid of the basket. Buster already seemed to
+have recognized the voice of his mistress, and, with an almost human instinct,
+to realize that though he himself was still weak and ill, she needed
+encouragement.
+</p>
+
+<p>
+As Mrs. Blake stretched out her slender hand, drawn with pain, to his silky
+head, he gave a little yelp of delight and his little red tongue eagerly
+caressed her hand.
+</p>
+
+<p>
+It was as though the two understood each other. Although Mrs. Blake, as yet,
+had no more idea what had happened to her pet, she seemed to feel by some
+subtle means of thought transference that the intelligent little animal was
+conveying to her a message of hope. The caress, the sharp, joyous yelp, and the
+happy wagging of the bushy tail seemed to brighten her up, at least for the
+moment, almost as if she had received a new impetus.
+</p>
+
+<p>
+“Buster!” she exclaimed, overjoyed to get her pet back again in so much
+improved condition.
+</p>
+
+<p>
+“I wouldn’t exert myself too much, Mrs. Blake,” cautioned Kennedy.
+</p>
+
+<p>
+“Were—were there any germs in the letter?” she asked, as Reginald and Betty
+stood on the other side of the chair, much encouraged, apparently, at this show
+of throwing off the lethargy that had seized her.
+</p>
+
+<p>
+“Yes, but about as harmless as those would be on a piece of cheese,” Kennedy
+hastened. “But I—I feel so weak, so played out—and my head—”
+</p>
+
+<p>
+Her voice trailed off, a too evident reminder that her improvement had been
+only momentary and prompted by the excitement of our arrival.
+</p>
+
+<p>
+Betty bent down solicitously and made her more comfortable as only one woman
+can make another. Kennedy, meanwhile, had been talking to Miss Rogers, and I
+could see that he was secretly taking her measure.
+</p>
+
+<p>
+“Has Dr. Wilson been here this morning?” I heard him ask.
+</p>
+
+<p>
+“Not yet,” she replied. “But we expect her soon.”
+</p>
+
+<p>
+“Professor Kennedy?” announced a servant.
+</p>
+
+<p>
+“Yes?” answered Craig.
+</p>
+
+<p>
+“There is someone on the telephone who wants to speak to you. He said he had
+called the laboratory first and that they told him to call you here.”
+</p>
+
+<p>
+Kennedy hurried after the servant, while Betty and Reginald joined me, waiting,
+for we seemed to feel that something was about to happen.
+</p>
+
+<p>
+“One of the unofficial detectives has unearthed a clue,” he whispered to me a
+few moments later when he returned. “It was Garwood.” Then to the others he
+added, “A car, repainted, and with the number changed, but otherwise answering
+the description of Dr. Wilson’s has been traced to the West Side. It is
+somewhere in the neighborhood of a saloon and garage where drivers of taxicabs
+hang out. Reginald, I wish you would come along with us.”
+</p>
+
+<p>
+To Betty’s unspoken question Craig hastened to add, “I don’t think there is any
+immediate danger. If there is any change—let me know. I shall call up soon. And
+meanwhile,” he lowered his voice to impress the instruction on her, “don’t
+leave your mother for a moment—not for a moment,” he emphasized.
+</p>
+
+<p>
+Reginald was ready and together we three set off to meet Garwood at a subway
+station near the point where the car had been reported. We had scarcely closed
+the front door, when we ran into Duncan Baldwin, coming down the street,
+evidently bent on inquiring how Mrs. Blake and Betty were.
+</p>
+
+<p>
+“Much better,” reassured Kennedy. “Come on, Baldwin. We can’t have too many on
+whom we can rely on an expedition like this.”
+</p>
+
+<p>
+“Like what?” he asked, evidently not comprehending.
+</p>
+
+<p>
+“There’s a clue, they think, to that car of Dr. Wilson’s,” hastily explained
+Reginald, linking his arm into that of his friend and falling in behind us, as
+Craig hurried ahead.
+</p>
+
+<p>
+It did not take long to reach the subway, and as we waited for the train, Craig
+remarked: “This is a pretty good example of how the automobile is becoming one
+of the most dangerous of criminal weapons. All one has to do nowadays,
+apparently, after committing a crime, is to jump into a waiting car and breeze
+away, safe.”
+</p>
+
+<p>
+We met Garwood and under his guidance picked our way westward from the better
+known streets in the heart of the city, to a section that was anything but
+prepossessing.
+</p>
+
+<p>
+The place which Garwood sought was a typical Raines Law hotel on a corner, with
+a saloon on the first floor, and apparently the requisite number of rooms above
+to give it a legal license.
+</p>
+
+<p>
+We had separated a little so that we would not attract undue attention. Kennedy
+and I entered the swinging doors boldly, while the others continued across to
+the other corner to wait with Garwood and take in the situation. It was a
+strange expedition and Reginald was fidgeting while Duncan seemed nervous.
+</p>
+
+<p>
+Among the group of chauffeurs lounging at the bar and in the back room anyone
+who had ever had any dealings with the gangs of New York might have recognized
+the faces of men whose pictures were in the rogues’ gallery and who were
+members of those various aristocratic organizations of the underworld.
+</p>
+
+<p>
+Kennedy glanced about at the motley crowd. “This is a place where you need only
+to be introduced properly,” he whispered to me, “to have any kind of crime
+committed for you.”
+</p>
+
+<p>
+As we stood there, observing, without appearing to do so, through an open
+window on the side street I could tell from the sounds that there was a garage
+in the rear of the hotel.
+</p>
+
+<p>
+We were startled to hear a sudden uproar from the street.
+</p>
+
+<p>
+Garwood, impatient at our delay, had walked down past the garage to
+reconnoiter. A car was being backed out hurriedly, and as it turned and swung
+around the corner, his trained eye had recognized it.
+</p>
+
+<p>
+Instantly he had reasoned that it was an attempt to make a getaway, and had
+raised an alarm.
+</p>
+
+<p>
+Those nearest the door piled out, keen for any excitement. We, too, dashed out
+on the street. There we saw passing an automobile, swaying and lurching at the
+terrific speed with which its driver, urged it up the avenue. As he flashed by
+he looked like an Italian to me, perhaps a gunman.
+</p>
+
+<p>
+Garwood had impressed a passing trolley car into service and was pursuing the
+automobile in it, as it swayed on its tracks as crazily as the motor did on the
+roadway, running with all the power the motorman could apply.
+</p>
+
+<p>
+A mounted policeman galloped past us, blazing away at the tires. The avenue was
+stirred, as seldom even in its strenuous life, with reports of shots, honking
+of horns, the clang of trolley bells and the shouts of men.
+</p>
+
+<p>
+The pursuers were losing when there came a rattle and roar from the rear wheels
+which told that the tires were punctured and the heavy car was riding on its
+rims. A huge brewery wagon crossing a side street paused to see the fun,
+effectually blocking the road.
+</p>
+
+<p>
+The car jolted to a stop. The chauffeur leaped out and a moment later dived
+down into a cellar. In that congested district, pursuit was useless.
+</p>
+
+<p>
+“Only an accomplice,” commented Kennedy. “Perhaps we can get him some other way
+if we can catch the man—or woman—higher up.”
+</p>
+
+<p>
+Down the street now we could see Garwood surrounded by a curious crowd but in
+possession of the car. I looked about for Duncan and Reginald. They had
+apparently been swallowed up in the crowds of idlers which seemed to be pouring
+out of nowhere, collecting to gape at the excitement, after the manner of a New
+York crowd.
+</p>
+
+<p>
+As I ran my eye over them, I caught sight of Reginald near the corner where we
+had left him in an incipient fight with someone who had a fancied grievance. A
+moment later we had rescued him.
+</p>
+
+<p>
+“Where’s Duncan?” he panted. “Did anything happen to him? Garwood told us to
+stay here—but we got separated.”
+</p>
+
+<p>
+Policemen had appeared on the heels of the crowd and now, except for a knot
+following Garwood, things seemed to be calming down.
+</p>
+
+<p>
+The excitement over, and the people thinning out, Kennedy still could not find
+any trace of Duncan. Finally he glanced in again through the swinging doors.
+There was Duncan, evidently quite upset by what had occurred, fortifying
+himself at the bar.
+</p>
+
+<p>
+Suddenly from above came a heavy thud, as if someone had fallen on the floor
+above us, followed by a suppressed shuffling of feet and a cry of help.
+</p>
+
+<p>
+Kennedy sprang toward a side door which led out into the hall to the hotel room
+above. It was locked. Before any of the others he ran out on the street and
+into the hall that way, taking the stairs two at a time, past a little
+cubby-hole of an “office” and down the upper hall to a door from which came the
+cry.
+</p>
+
+<p>
+It was a peculiar room into which we burst, half bedroom, half workshop, or
+rather laboratory, for on a deal table by a window stood a rack of test-tubes,
+several beakers, and other paraphernalia.
+</p>
+
+<p>
+A chambermaid was shrieking over a woman who was lying lethargic on the floor.
+</p>
+
+<p>
+I looked more closely.
+</p>
+
+<p>
+It was Dora Sears.
+</p>
+
+<p>
+For the moment I could not imagine what had happened. Had the events of the
+past few days worked on her mind and driven her into temporary insanity? Or had
+the blackmailing gang of automobile thieves, failing in extorting money by
+their original plan, seized her?
+</p>
+
+<p>
+Kennedy bent over and tried to lift her up. As he did so, the gold bracelet,
+unclasped, clattered to the floor.
+</p>
+
+<p>
+He picked it up and for a moment looked at it. It was hollow, but in that part
+of it where it unclasped could be seen a minute hypodermic needle and traces of
+a liquid.
+</p>
+
+<p>
+“A poison bracelet,” he muttered to himself, “one in which enough of a virulent
+poison could be hidden so that in an emergency death could cheat the law.”
+</p>
+
+<p>
+“But this Dr. Hopf,” exclaimed Reginald, who stood behind us looking from the
+insensible girl to the bracelet and slowly comprehending what it all meant,
+“she alone knows where and who he is!”
+</p>
+
+<p>
+We looked at Kennedy. What was to be done? Was the criminal higher up to escape
+because one of his tools had been cornered and had taken the easiest way to get
+out?
+</p>
+
+<p>
+Kennedy had taken down the receiver of the wall telephone in the room. A moment
+later he was calling insistently for his laboratory. One of the students in
+another part of the building answered. Quickly he described the apparatus for
+vividiffusion and how to handle it without rupturing any of the delicate tubes.
+</p>
+
+<p>
+“The large one,” he ordered, “with one hundred and ninety-two tubes. And
+hurry.”
+</p>
+
+<p>
+Before the student appeared, came an ambulance which some one in the excitement
+had summoned. Kennedy quickly commandeered both the young doctor and what
+surgical material he had with him.
+</p>
+
+<p>
+Briefly he explained what he proposed to do and before the student arrived with
+the apparatus, they had placed the nurse in such a position that they were
+ready for the operation.
+</p>
+
+<p>
+The next room which was unoccupied had been thrown open to us and there I
+waited with Reginald and Duncan, endeavoring to explain to them the mysteries
+of the new process of washing the blood.
+</p>
+
+<p>
+The minutes lengthened into hours, as the blood of the poisoned girl coursed
+through its artificial channel, literally being washed of the toxin from the
+poisoned bracelet.
+</p>
+
+<p>
+Would it succeed? It had saved the life of Buster. But would it bring back the
+unfortunate before us, long enough even for her to yield her secret and enable
+us to catch the real criminal. What if she died?
+</p>
+
+<p>
+As Kennedy worked, the young men with me became more and more fascinated,
+watching him. The vividiffusion apparatus was now in full operation.
+</p>
+
+<p>
+In the intervals when he left the apparatus in charge of the young ambulance
+surgeon Kennedy was looking over the room. In a trunk which was open he found
+several bundles of papers. As he ran his eye over them quickly, he selected
+some and stuffed them into his pocket, then went back to watch the working of
+the apparatus.
+</p>
+
+<p>
+Reginald, who had been growing more and more nervous, at last asked if he might
+call up Betty to find out how his mother was.
+</p>
+
+<p>
+He came back from the telephone, his face wrinkled.
+</p>
+
+<p>
+“Poor mother,” he remarked anxiously, “do you think she will pull through,
+Professor? Betty says that Dr. Wilson has given her no idea yet about the
+nature of the trouble.”
+</p>
+
+<p>
+Kennedy thought a moment. “Of course,” he said, “your mother has had no such
+relative amount of the poison as Buster has had. I think that undoubtedly she
+will recover by purely natural means. I hope so. But if not, here is the
+apparatus,” and he patted the vividiffusion tubes in their glass case, “that
+will save her, too.”
+</p>
+
+<p>
+As well as I could I explained to Reginald the nature of the toxin that Kennedy
+had discovered. Duncan listened, putting in a question now and then. But it was
+evident that his thoughts were on something else, and now and then Reginald,
+breaking into his old humor, rallied him about thinking of Betty.
+</p>
+
+<p>
+A low exclamation from both Kennedy and the surgeon attracted us.
+</p>
+
+<p>
+Dora Sears had moved.
+</p>
+
+<p>
+The operation of the apparatus was stopped, the artery and vein had been joined
+up, and she was slowly coming out from under the effects of the anesthetic.
+</p>
+
+<p>
+As we gathered about her, at a little distance, we heard her cry in her
+delirium, “I—I would have—done—anything—for him.”
+</p>
+
+<p>
+We strained our ears. Was she talking of the blackmailer, Dr. Hopf?
+</p>
+
+<p>
+“Who?” asked Craig, bending over close to her ear.
+</p>
+
+<p>
+“I—I would—have done anything,” she repeated as if someone had contradicted
+her. She went on, dreamily, ramblingly, “He—is—is—my brother. I—”
+</p>
+
+<p>
+She stopped through weakness.
+</p>
+
+<p>
+“Where is Dr. Hopf?” asked Kennedy, trying to recall her fleeting attention.
+</p>
+
+<p>
+“Dr. Hopf? Dr. Hopf?” she repeated, then smiling to herself as people will when
+they are leaving the borderline of anesthesia, she repeated the name, “Hopf?”
+</p>
+
+<p>
+“Yes,” persisted Kennedy.
+</p>
+
+<p>
+“There is no Dr. Hopf,” she added. “Tell me—did—did they—”
+</p>
+
+<p>
+“No Dr. Hopf?” Kennedy insisted.
+</p>
+
+<p>
+She had lapsed again into half insensibility.
+</p>
+
+<p>
+He rose and faced us, speaking rapidly.
+</p>
+
+<p>
+“New York seems to have a mysterious and uncanny attraction for odds and ends
+of humanity, among them the great army of adventuresses. In fact there often
+seems to be something decidedly adventurous about the nursing profession. This
+is a girl of unusual education in medicine. Evidently she has traveled—her
+letters show it. Many of them show that she has been in Italy. Perhaps it was
+there that she heard of the drug that has been used in this case. It was she
+who injected the germ-free toxin, first into the dog, then into Mrs. Blake, she
+who wrote the blackmail letter which was to have explained the death.”
+</p>
+
+<p>
+He paused. Evidently she had heard dimly, was straining every effort to hear.
+In her effort she caught sight of our faces.
+</p>
+
+<p>
+Suddenly, as if she had seen an apparition, she raised herself with almost
+superhuman strength.
+</p>
+
+<p>
+“Duncan!” she cried. “Duncan! Why—didn’t you—get away—while there was
+time—after you warned me?”
+</p>
+
+<p>
+Kennedy had wheeled about and was facing us. He was holding in his hand some of
+the letters he had taken from the trunk. Among others was a folded piece of
+parchment that looked like a diploma. He unfolded it and we bent over to read.
+</p>
+
+<p>
+It was a diploma from the Central Western College of Nursing. As I read the
+name written in, it was with a shock. It was not Dora Sears, but Dora Baldwin.
+</p>
+
+<p>
+“A very clever plot,” he ground out, taking a step nearer us. “With the aid of
+your sister and a disreputable gang of chauffeurs you planned to hasten the
+death of Mrs. Blake, to hasten the inheritance of the Blake fortune by your
+future wife. I think your creditors will have less chance of collecting now
+than ever, Duncan Baldwin.”

+<h2><a name="chap22"></a>CHAPTER XXII<br/>
+THE DEVIL WORSHIPERS</h2>
+
+<p>
+Tragic though the end of the young nurse, Dora Baldwin, had been, the scheme of
+her brother, in which she had become fatally involved, was by no means as
+diabolical as that in the case that confronted us a short time after that.
+</p>
+
+<p>
+I recall this case particularly not only because it was so weird but also
+because of the unique manner in which it began.
+</p>
+
+<p>
+“I am damned—Professor Kennedy—damned!”
+</p>
+
+<p>
+The words rang out as the cry of a lost soul. A terrible look of inexpressible
+anguish and fear was written on the face of Craig’s visitor, as she uttered
+them and sank back, trembling, in the easy chair, mentally and physically
+convulsed.
+</p>
+
+<p>
+As nearly as I had been able to follow, Mrs. Veda Blair’s story had dealt
+mostly with a Professor and Madame Rapport and something she called the “Red
+Lodge” of the “Temple of the Occult.”
+</p>
+
+<p>
+She was not exactly a young woman, although she was a very attractive one. She
+was of an age that is, perhaps, even more interesting than youth.
+</p>
+
+<p>
+Veda Blair, I knew, had been, before her recent marriage to Seward Blair, a
+Treacy, of an old, though somewhat unfortunate, family. Both the Blairs and the
+Treacys had been intimate and old Seward Blair, when he died about a year
+before, had left his fortune to his son on the condition that he marry Veda
+Treacy.
+</p>
+
+<p>
+“Sometimes,” faltered Mrs. Blair, “it is as though I had two souls. One of them
+is dispossessed of its body and the use of its organs and is frantic at the
+sight of the other that has crept in.”
+</p>
+
+<p>
+She ended her rambling story, sobbing the terrible words, “Oh—I have committed
+the unpardonable sin—I am anathema—I am damned—damned!”
+</p>
+
+<p>
+She said nothing of what terrible thing she had done and Kennedy, for the
+present, did not try to lead the conversation. But of all the stories that I
+have heard poured forth in the confessional of the detective’s office, hers, I
+think, was the wildest.
+</p>
+
+<p>
+Was she insane? At least I felt that she was sincere. Still, I wondered what
+sort of hallucination Craig had to deal with, as Veda Blair repeated the
+incoherent tale of her spiritual vagaries.
+</p>
+
+<p>
+Almost, I had begun to fancy that this was a case for a doctor, not for a
+detective, when suddenly she asked a most peculiar question.
+</p>
+
+<p>
+“Can people affect you for good or evil, merely by thinking about you?” she
+queried. Then a shudder passed over her. “They may be thinking about me now!”
+she murmured in terror.
+</p>
+
+<p>
+Her fear was so real and her physical distress so evident that Kennedy, who had
+been listening silently for the most part, rose and hastened to reassure her.
+</p>
+
+<p>
+“Not unless you make your own fears affect yourself and so play into their
+hands,” he said earnestly.
+</p>
+
+<p>
+Veda looked at him a moment, then shook her head mournfully. “I have seen Dr.
+Vaughn,” she said slowly.
+</p>
+
+<p>
+Dr. Gilbert Vaughn, I recollected, was a well-known alienist in the city.
+</p>
+
+<p>
+“He tried to tell me the same thing,” she resumed doubtfully. “But—oh—I know
+what I know! I have felt the death thought—and he knows it!”
+</p>
+
+<p>
+“What do you mean?” inquired Kennedy, leaning forward keenly.
+</p>
+
+<p>
+“The death thought,” she repeated, “a malicious psychic attack. Some one is
+driving me to death by it. I thought I could fight it off. I went away to
+escape it. Now I have come back—and I have not escaped. There is always that
+disturbing influence—always—directed against me. I know it will—kill me!”
+</p>
+
+<p>
+I listened, startled. The death thought! What did it mean? What terrible power
+was it? Was it hypnotism? What was this fearsome, cruel belief, this modern
+witchcraft that could unnerve a rich and educated woman? Surely, after all, I
+felt that this was not a case for a doctor alone; it called for a detective.
+</p>
+
+<p>
+“You see,” she went on, heroically trying to control herself, “I have always
+been interested in the mysterious, the strange, the occult. In fact my father
+and my husband’s father met through their common interest. So, you see, I come
+naturally by it.
+</p>
+
+<p>
+“Not long ago I heard of Professor and Madame Rapport and their new Temple of
+the Occult. I went to it, and later Seward became interested, too. We have been
+taken into a sort of inner circle,” she continued fearfully, as though there
+were some evil power in the very words themselves, “the Red Lodge.”
+</p>
+
+<p>
+“You have told Dr. Vaughn?” shot out Kennedy suddenly, his eyes fixed on her
+face to see what it would betray.
+</p>
+
+<p>
+Veda leaned forward, as if to tell a secret, then whispered in a low voice, “He
+knows. Like us—he—he is a—Devil Worshiper!”
+</p>
+
+<p>
+“What?” exclaimed Kennedy in wide-eyed astonishment.
+</p>
+
+<p>
+“A Devil Worshiper,” she repeated. “You haven’t heard of the Red Lodge?”
+</p>
+
+<p>
+Kennedy nodded negatively. “Could you get us—initiated?” he hazarded.
+</p>
+
+<p>
+“P—perhaps,” she hesitated, in a half-frightened tone. “I—I’ll try to get you
+in to-night.”
+</p>
+
+<p>
+She had risen, half dazed, as if her own temerity overwhelmed her.
+</p>
+
+<p>
+“You—poor girl,” blurted out Kennedy, his sympathies getting the upper hand for
+the moment as he took the hand she extended mutely. “Trust me. I will do all in
+my power, all in the power of modern science to help you fight off
+this—influence.”
+</p>
+
+<p>
+There must have been something magnetic, hypnotic in his eye.
+</p>
+
+<p>
+“I will stop here for you,” she murmured, as she almost fled from the room.
+</p>
+
+<p>
+Personally, I cannot say that I liked the idea of spying. It is not usually
+clean and wholesome. But I realized that occasionally it was necessary.
+</p>
+
+<p>
+“We are in for it now,” remarked Kennedy half humorously, half seriously, “to
+see the Devil in the twentieth century.”
+</p>
+
+<p>
+“And I,” I added, “I am, I suppose, to be the reporter to Satan.”
+</p>
+
+<p>
+We said nothing more about it, but I thought much about it, and the more I
+thought, the more incomprehensible the thing seemed. I had heard of Devil
+Worship, but had always associated it with far-off Indian and other heathen
+lands—in fact never among Caucasians in modern times, except possibly in Paris.
+Was there such a cult here in my own city? I felt skeptical.
+</p>
+
+<p>
+That night, however, promptly at the appointed time, a cab called for us, and
+in it was Veda Blair, nervous but determined.
+</p>
+
+<p>
+“Seward has gone ahead,” she explained. “I told him that a friend had
+introduced you, that you had studied the occult abroad. I trust you to carry it
+out.”
+</p>
+
+<p>
+Kennedy reassured her.
+</p>
+
+<p>
+The curtains were drawn and we could see nothing outside, though we must have
+been driven several miles, far out into the suburbs.
+</p>
+
+<p>
+At last the cab stopped. As we left it we could see nothing of the building,
+for the cab had entered a closed courtyard.
+</p>
+
+<p>
+“Who enters the Red Lodge?” challenged a sepulchral voice at the porte-cochère.
+“Give the password!”
+</p>
+
+<p>
+“The Serpent’s Tooth,” Veda answered.
+</p>
+
+<p>
+“Who are these?” asked the voice.
+</p>
+
+<p>
+“Neophytes,” she replied, and a whispered parley followed.
+</p>
+
+<p>
+“Then enter!” announced the voice at length.
+</p>
+
+<p>
+It was a large room into which we were first ushered, to be inducted into the
+rites of Satan.
+</p>
+
+<p>
+There seemed to be both men and women, perhaps half a dozen votaries. Seward
+Blair was already present. As I met him, I did not like the look in his eye; it
+was too stary. Dr. Vaughn was there, too, talking in a low tone to Madame
+Rapport. He shot a quick look at us. His were not eyes but gimlets that tried
+to bore into your very soul. Chatting with Seward Blair was a Mrs. Langhorne, a
+very beautiful woman. To-night she seemed to be unnaturally excited.
+</p>
+
+<p>
+All seemed to be on most intimate terms, and, as we waited a few minutes, I
+could not help recalling a sentence from Huysmans: “The worship of the Devil is
+no more insane than the worship of God. The worshipers of Satan are
+mystics—mystics of an unclean sort, it is true, but mystics none the less.”
+</p>
+
+<p>
+I did not agree with it, and did not repeat it, of course, but a moment later I
+overheard Dr. Vaughn saying to Kennedy: “Hoffman brought the Devil into modern
+life. Poe forgoes the aid of demons and works patiently and precisely by the
+scientific method. But the result is the same.”
+</p>
+
+<p>
+“Yes,” agreed Kennedy for the sake of appearances, “in a sense, I suppose, we
+are all devil worshipers in modern society—always have been. It is fear that
+rules and we fear the bad—not the good.”
+</p>
+
+<p>
+As we waited, I felt, more and more, the sense of the mysterious, the secret,
+the unknown which have always exercised a powerful attraction on the human
+mind. Even the aeroplane and the submarine, the X-ray and wireless have not
+banished the occult.
+</p>
+
+<p>
+In it, I felt, there was fascination for the frivolous and deep appeal to the
+intellectual and spiritual. The Temple of the Occult had evidently been
+designed to appeal to both types. I wondered how, like Lucifer, it had fallen.
+The prime requisite, I could guess already, however, was—money. Was it in its
+worship of the root of all evil that it had fallen?
+</p>
+
+<p>
+We passed soon into another room, hung entirely in red, with weird, cabalistic
+signs all about, on the walls. It was uncanny, creepy.
+</p>
+
+<p>
+A huge reproduction in plaster of one of the most sardonic of Notre Dame’s
+gargoyles seemed to preside over everything—a terrible figure in such an
+atmosphere.
+</p>
+
+<p>
+As we entered, we were struck by the blinding glare of the light, in contrast
+with the darkened room in which we had passed our brief novitiate, if it might
+be called such.
+</p>
+
+<p>
+Suddenly the lights were extinguished.
+</p>
+
+<p>
+The great gargoyle shone with an infernal light of its own!
+</p>
+
+<p>
+“Phosphorescent paint,” whispered Kennedy to me.
+</p>
+
+<p>
+Still, it did not detract from the weird effect to know what caused it.
+</p>
+
+<p>
+There was a startling noise in the general hush.
+</p>
+
+<p>
+“Sata!” cried one of the devotees.
+</p>
+
+<p>
+A door opened and there appeared the veritable priest of the Devil—pale of
+face, nose sharp, mouth bitter, eyes glassy.
+</p>
+
+<p>
+“That is Rapport,” Vaughn whispered to me.
+</p>
+
+<p>
+The worshipers crowded forward.
+</p>
+
+<p>
+Without a word, he raised his long, lean forefinger and began to single them
+out impressively. As he did so, each spoke, as if imploring aid.
+</p>
+
+<p>
+He came to Mrs. Langhorne.
+</p>
+
+<p>
+“I have tried the charm,” she cried earnestly, “and the one whom I love still
+hates me, while the one I hate loves me!”
+</p>
+
+<p>
+“Concentrate!” replied the priest, “concentrate! Think always ‘I love him. He
+must love me. I want him to love me. I love him. He must love me.’ Over and
+over again you must think it. Then the other side, ‘I hate him. He must leave
+me. I want him to leave me. I hate him—hate him.’”
+</p>
+
+<p>
+Around the circle he went.
+</p>
+
+<p>
+At last his lean finger was outstretched at Veda. It seemed as if some imp of
+the perverse were compelling her unwilling tongue to unlock its secrets.
+</p>
+
+<p>
+“Sometimes,” she cried in a low, tremulous voice, “something seems to seize me,
+as if by the hand and urge me onward. I cannot flee from it.”
+</p>
+
+<p>
+“Defend yourself!” answered the priest subtly. “When you know that some one is
+trying to kill you mentally, defend yourself! Work against it by every means in
+your power. Discourage! Intimidate! Destroy!”
+</p>
+
+<p>
+I marveled at these cryptic utterances. They shadowed a modern Black Art, of
+which I had had no conception—a recrudescence in other language of the age-old
+dualism of good and evil. It was a sort of mental malpractice.
+</p>
+
+<p>
+“Over and over again,” he went on speaking to her, “the same thought is to be
+repeated against an enemy. ‘You know you are going to die! You know you are
+going to die!’ Do it an hour, two hours, at a time. Others can help you, all
+thinking in unison the same thought.”
+</p>
+
+<p>
+What was this, I asked myself breathlessly—a new transcendental toxicology?
+</p>
+
+<p>
+Slowly, a strange mephitic vapor seemed to exhale into the room—or was it my
+heightened imagination?
+</p>

+<h2><a name="chap23"></a>CHAPTER XXIII<br/>
+THE PSYCHIC CURSE</h2>
+
+<p>
+There came a sudden noise—nameless—striking terror, low, rattling. I stood
+rooted to the spot. What was it that held me? Was it an atavistic joy in the
+horrible or was it merely a blasphemous curiosity?
+</p>
+
+<p>
+I scarcely dared to look.
+</p>
+
+<p>
+At last I raised my eyes. There was a live snake, upraised, his fangs striking
+out viciously—a rattler!
+</p>
+
+<p>
+I would have drawn back and fled, but Craig caught my arm.
+</p>
+
+<p>
+“Caged,” he whispered monosyllabically.
+</p>
+
+<p>
+I shuddered. This, at least, was no drawing-room diablerie.
+</p>
+
+<p>
+“It is Ophis,” intoned Rapport, “the Serpent—the one active form in Nature that
+cannot be ungraceful!”
+</p>
+
+<p>
+The appearance of the basilisk seemed to heighten the tension.
+</p>
+
+<p>
+At last it broke loose and then followed the most terrible blasphemies. The
+disciples, now all frenzied, surrounded closer the priest, the gargoyle and the
+serpent.
+</p>
+
+<p>
+They worshiped with howls and obscenities. Mad laughter mingled with pale fear
+and wild scorn in turns were written on the hectic faces about me.
+</p>
+
+<p>
+They had risen—it became a dance, a reel.
+</p>
+
+<p>
+The votaries seemed to spin about on their axes, as it were, uttering a low,
+moaning chant as they whirled. It was a mania, the spirit of demonism.
+Something unseen seemed to urge them on.
+</p>
+
+<p>
+Disgusted and stifled at the surcharged atmosphere, I would have tried to
+leave, but I seemed frozen to the spot. I could think of nothing except Poe’s
+Masque of the Red Death.
+</p>
+
+<p>
+Above all the rest whirled Seward Blair himself. The laugh of the fiend, for
+the moment, was in his mouth. An instant he stood—the oracle of the
+Demon—devil-possessed. Around whirled the frantic devotees, howling.
+</p>
+
+<p>
+Shrilly he cried, “The Devil is in me!”
+</p>
+
+<p>
+Forward staggered the devil dancer—tall, haggard, with deep sunken eyes and
+matted hair, face now smeared with dirt and blood-red with the reflection of
+the strange, unearthly phosphorescence.
+</p>
+
+<p>
+He reeled slowly through the crowd, crooning a quatrain, in a low, monotonous
+voice, his eyelids drooping and his head forward on his breast:
+</p>
+
+<p class="poem">
+If the Red Slayer think he slays,<br/>
+    Or the slain think he is slain,<br/>
+They know not well the subtle ways<br/>
+    I keep and pass and turn again!
+</p>
+
+<p>
+Entranced the whirling crowd paused and watched. One of their number had
+received the “power.”
+</p>
+
+<p>
+He was swaying slowly to and fro.
+</p>
+
+<p>
+“Look!” whispered Kennedy.
+</p>
+
+<p>
+His fingers twitched, his head wagged uncannily. Perspiration seemed to ooze
+from every pore. His breast heaved.
+</p>
+
+<p>
+He gave a sudden yell—ear-piercing. Then followed a screech of hellish
+laughter.
+</p>
+
+<p>
+The dance had ended, the dancers spellbound at the sight.
+</p>
+
+<p>
+He was whirling slowly, eyes protruding now, mouth foaming, chest rising and
+falling like a bellows, muscles quivering.
+</p>
+
+<p>
+Cries, vows, imprecations, prayers, all blended in an infernal hubbub.
+</p>
+
+<p>
+With a burst of ghastly, guttural laughter, he shrieked, “I <i>am</i> the
+Devil!”
+</p>
+
+<p>
+His arms waved—cutting, sawing, hacking the air.
+</p>
+
+<p>
+The votaries, trembling, scarcely moved, breathed, as he danced.
+</p>
+
+<p>
+Suddenly he gave a great leap into the air—then fell, motionless. They crowded
+around him. The fiendish look was gone—the demoniac laughter stilled.
+</p>
+
+<p>
+It was over.
+</p>
+
+<p>
+The tension of the orgy had been too much for us. We parted, with scarcely a
+word, and yet I could feel that among the rest there was a sort of unholy
+companionship.
+</p>
+
+<p>
+Silently, Kennedy and I drove away in the darkened cab, this time with Seward
+and Veda Blair and Mrs. Langhorne.
+</p>
+
+<p>
+For several minutes not a word was said. I was, however, much occupied in
+watching the two women. It was not because of anything they said or did. That
+was not necessary. But I felt that there was a feud, something that set them
+against each other.
+</p>
+
+<p>
+“How would Rapport use the death thought, I wonder?” asked Craig speculatively,
+breaking the silence.
+</p>
+
+<p>
+Blair answered quickly. “Suppose some one tried to break away, to renounce the
+Lodge, expose its secrets. They would treat him so as to make him
+harmless—perhaps insane, confused, afraid to talk, paralyzed, or even to commit
+suicide or be killed in an accident. They would put the death thought on him!”
+</p>
+
+<p>
+Even in the prosaic jolting of the cab, away from the terrible mysteries of the
+Red Lodge, one could feel the spell.
+</p>
+
+<p>
+The cab stopped. Seward was on his feet in a moment and handing Mrs. Langhorne
+out at her home. For a moment they paused on the steps for an exchange of
+words.
+</p>
+
+<p>
+In that moment I caught flitting over the face of Veda a look of hatred, more
+intense, more real, more awful than any that had been induced under the
+mysteries of the rites at the Lodge.
+</p>
+
+<p>
+It was gone in an instant, and as Seward rejoined us I felt that, with Mrs.
+Langhorne gone, there was less restraint. I wondered whether it was she who had
+inspired the fear in Veda.
+</p>
+
+<p>
+Although it was more comfortable, the rest of our journey was made in silence
+and the Blairs dropped us at our apartment with many expressions of cordiality
+as we left them to proceed to their own.
+</p>
+
+<p>
+“Of one thing I’m sure,” I remarked, entering the room where only a few short
+hours before Mrs. Blair had related her strange tale. “Whatever the cause of
+it, the devil dancers don’t sham.”
+</p>
+
+<p>
+Kennedy did not reply. He was apparently wrapped up in the consideration of the
+remarkable events of the evening.
+</p>
+
+<p>
+As for myself, it was a state of affairs which, the day before, I should have
+pronounced utterly beyond the wildest bounds of the imagination of the most
+colorful writer. Yet here it was; I had seen it.
+</p>
+
+<p>
+I glanced up to find Kennedy standing by the light examining something he had
+apparently picked up at the Red Lodge. I bent over to look at it, too. It was a
+little glass tube.
+</p>
+
+<p>
+“An ampoule, I believe the technical name of such a container is,” he remarked,
+holding it closer to the light.
+</p>
+
+<p>
+In it were the remains of a dried yellow substance, broken up minutely,
+resembling crystals.
+</p>
+
+<p>
+“Who dropped it?” I asked.
+</p>
+
+<p>
+“Vaughn, I think,” he replied. “At least, I saw him near Blair, stooping over
+him, at the end, and I imagine this is what I saw gleaming for an instant in
+the light.”
+</p>
+
+<p>
+Kennedy said nothing more, and for my part I was thoroughly at sea and could
+make nothing out of it all.
+</p>
+
+<p>
+“What object can such a man as Dr. Vaughn possibly have in frequenting such a
+place?” I asked at length, adding, “And there’s that Mrs. Langhorne—she was
+interesting, too.”
+</p>
+
+<p>
+Kennedy made no direct reply. “I shall have them shadowed to-morrow,” he said
+briefly, “while I am at work in the laboratory over this ampoule.”
+</p>
+
+<p>
+As usual, also, Craig had begun on his scientific studies long before I was
+able to shake myself loose from the nightmares that haunted me after our weird
+experience of the evening.
+</p>
+
+<p>
+He had already given the order to an agency for the shadowing, and his next
+move was to start me out, also, looking into the history of those concerned in
+the case. As far as I was able to determine, Dr. Vaughn had an excellent
+reputation, and I could find no reason whatever for his connection with
+anything of the nature of the Red Lodge. The Rapports seemed to be nearly
+unknown in New York, although it was reported that they had come from Paris
+lately. Mrs. Langhorne was a divorcée from one of the western states, but
+little was known about her, except that she always seemed to be well supplied
+with money. It seemed to be well known in the circle in which Seward Blair
+moved that he was friendly with her, and I had about reached the conclusion
+that she was unscrupulously making use of his friendship, perhaps was not above
+such a thing as blackmail.
+</p>
+
+<p>
+Thus the day passed, and we heard no word from Veda Blair, although that was
+explained by the shadows, whose trails crossed in a most unexpected manner.
+Their reports showed that there was a meeting at the Red Lodge during the late
+afternoon, at which all had been present except Dr. Vaughn. We learned also
+from them the exact location of the Lodge, in an old house just across the line
+in Westchester.
+</p>
+
+<p>
+It was evidently a long and troublesome analysis that Craig was engaged in at
+the laboratory, for it was some hours after dinner that night when he came into
+the apartment, and even then he said nothing, but buried himself in some of the
+technical works with which his library was stocked. He said little, but I
+gathered that he was in great doubt about something, perhaps, as much as
+anything, about how to proceed with so peculiar a case.
+</p>
+
+<p>
+It was growing late, and Kennedy was still steeped in his books, when the door
+of the apartment, which we happened to have left unlocked, was suddenly thrown
+open and Seward Blair burst in on us, wildly excited.
+</p>
+
+<p>
+“Veda is gone!” he cried, before either of us could ask him what was the
+matter.
+</p>
+
+<p>
+“Gone?” repeated Kennedy. “How—where?”
+</p>
+
+<p>
+“I don’t know,” Blair blurted out breathlessly. “We had been out together this
+afternoon, and I returned with her. Then I went out to the club after dinner
+for a while, and when I got back I missed her—not quarter of an hour ago. I
+burst into her room—and there I found this note. Read it. I don’t know what to
+do. No one seems to know what has become of her. I’ve called up all over and
+then thought perhaps you might help me, might know some friend of hers that I
+don’t know, with whom she might have gone out.”
+</p>
+
+<p>
+Blair was plainly eager for us to help him. Kennedy took the paper from him. On
+it, in a trembling hand, were scrawled some words, evidently addressed to Blair
+himself:
+</p>
+
+<p class="p2">
+“You would forgive me and pity me if you knew what I have been through.
+</p>
+
+<p>
+“When I refused to yield my will to the will of the Lodge I suppose I aroused
+the enmity of the Lodge.
+</p>
+
+<p>
+“To-night as I lay in bed, alone, I felt that my hour had come, that mental
+forces that were almost irresistible were being directed against me.
+</p>
+
+<p>
+“I realized that I must fight not only for my sanity but for my life.
+</p>
+
+<p>
+“For hours I have fought that fight.
+</p>
+
+<p>
+“But during those hours, some one, I won’t say who, seemed to have developed
+such psychic faculties of penetration that they were able to make their bodies
+pass through the walls of my room.
+</p>
+
+<p>
+“At last I am conquered. I pray that you—”
+</p>
+
+<p class="p2">
+The writing broke off abruptly, as if she had left it in wild flight.
+</p>
+
+<p>
+“What does that mean?” asked Kennedy, “the ‘will of the Lodge’?”
+</p>
+
+<p>
+Blair looked at us keenly. I fancied that there was even something accusatory
+in the look. “Perhaps it was some mental reservation on her part,” he
+suggested. “You do not know yourself of any reason why she should fear
+anything, do you?” he asked pointedly.
+</p>
+
+<p>
+Kennedy did not betray even by the motion of an eyelash that we knew more than
+we should ostensibly.
+</p>
+
+<p>
+There was a tap at the door. I sprang to open it, thinking perhaps, after all,
+it was Veda herself.
+</p>
+
+<p>
+Instead, a man, a stranger, stood there.
+</p>
+
+<p>
+“Is this Professor Kennedy?” he asked, touching his hat.
+</p>
+
+<p>
+Craig nodded.
+</p>
+
+<p>
+“I am from the psychopathic ward of the City Hospital—an orderly, sir,” the man
+introduced.
+</p>
+
+<p>
+“Yes,” encouraged Craig, “what can I do for you?”
+</p>
+
+<p>
+“A Mrs. Blair has just been brought in, sir, and we can’t find her husband.
+She’s calling for you now.”
+</p>
+
+<p>
+Kennedy stared from the orderly to Seward Blair, startled, speechless.
+</p>
+
+<p>
+“What has happened?” asked Blair anxiously. “I am Mr. Blair.”
+</p>
+
+<p>
+The orderly shook his head. He had delivered his message. That was all he knew.
+</p>
+
+<p>
+“What do you suppose it is?” I asked, as we sped across town in a taxicab. “Is
+it the curse that she dreaded?”
+</p>
+
+<p>
+Kennedy said nothing and Blair appeared to hear nothing. His face was drawn in
+tense lines.
+</p>
+
+<p>
+The psychopathic ward is at once one of the most interesting and one of the
+most depressing departments of a large city hospital, harboring, as it does,
+all from the more or less harmless insane to violent alcoholics and wrecked
+drug fiends.
+</p>
+
+<p>
+Mrs. Blair, we learned, had been found hatless, without money, dazed, having
+fallen, after an apparently aimless wandering in the streets.
+</p>
+
+<p>
+For the moment she lay exhausted on the white bed of the ward, eyes glazed,
+pupils contracted, pulse now quick, now almost evanescent, face drawn,
+breathing difficult, moaning now and then in physical and mental agony.
+</p>
+
+<p>
+Until she spoke it was impossible to tell what had happened, but the ambulance
+surgeon had found a little red mark on her white forearm and had pointed it
+out, evidently with the idea that she was suffering from a drug.
+</p>
+
+<p>
+At the mere sight of the mark, Blair stared as though hypnotized. Leaning over
+to Kennedy, so that the others could not hear, he whispered, “It is the mark of
+the serpent!”
+</p>
+
+<p>
+Our arrival had been announced to the hospital physician, who entered and stood
+for a moment looking at the patient.
+</p>
+
+<p>
+“I think it is a drug—a poison,” he said meditatively.
+</p>
+
+<p>
+“You haven’t found out yet what it is, then?” asked Craig.
+</p>
+
+<p>
+The physician shook his head doubtfully. “Whatever it is,” he said slowly, “it
+is closely allied to the cyanide groups in its rapacious activity. I haven’t
+the slightest idea of its true nature, but it seems to have a powerful affinity
+for important nerve centers of respiration and muscular coordination, as well
+as for disorganizing the blood. I should say that it produces death by
+respiratory paralysis and convulsions. To my mind it is an exact, though
+perhaps less active, counterpart of hydrocyanic acid.”
+</p>
+
+<p>
+Kennedy had been listening intently at the start, but before the physician had
+finished he had bent over and made a ligature quickly with his handkerchief.
+</p>
+
+<p>
+Then he dispatched a messenger with a note. Next he cut about the minute wound
+on her arm until the blood flowed, cupping it to increase the flow. Now and
+then he had them administer a little stimulant.
+</p>
+
+<p>
+He had worked rapidly, while Blair watched him with a sort of fascination.
+</p>
+
+<p>
+“Get Dr. Vaughn,” ordered Craig, as soon as he had a breathing spell after his
+quick work, adding, “and Professor and Madame Rapport. Walter, attend to that,
+will you? I think you will find an officer outside. You’ll have to compel them
+to come, if they won’t come otherwise,” he added, giving the address of the
+Lodge, as we had found it.
+</p>
+
+<p>
+Blair shot a quick look at him, as though Craig in his knowledge were uncanny.
+Apparently, the address had been a secret which he thought we did not know.
+</p>
+
+<p>
+I managed to find an officer and dispatch him for the Rapports. A hospital
+orderly, I thought, would serve to get Dr. Vaughn.

+THE SERPENT’S TOOTH</h2>
+
+<p>
+I had scarcely returned to the ward when, suddenly, an unnatural strength
+seemed to be infused into Veda.
+</p>
+
+<p>
+She had risen in bed.
+</p>
+
+<p>
+“It shall not catch me!” she cried in a new paroxysm of nameless terror.
+“No—no—it is pursuing me. I am never out of its grasp. I have been thought six
+feet underground—I know it. There it is again—still driving me—still driving
+me!
+</p>
+
+<p>
+“Will it never stop? Will no one stop it? Save me! It—is the death thought!”
+</p>
+
+<p>
+She had risen convulsively and had drawn back in abject, cowering terror. What
+was it she saw? Evidently it was very real and very awful. It pursued her
+relentlessly.
+</p>
+
+<p>
+As she lay there, rolling her eyes about, she caught sight of us and recognized
+us for the first time, although she had been calling for us.
+</p>
+
+<p>
+“They had the thought on you, too, Professor Kennedy,” she almost screamed.
+“Hour after hour, Rapport and the rest repeated over and over again, ‘Why does
+not some one kill him? Why does he not die?’ They knew you—even when I brought
+you to the Red Lodge. They thought you were a spy.”
+</p>
+
+<p>
+I turned to Kennedy. He had advanced and was leaning over to catch every word.
+Blair was standing behind me and she had not seen her husband yet. A quick
+glance showed me that he was trembling from head to foot like a leaf, as though
+he, too, were pursued by the nameless terror.
+</p>
+
+<p>
+“What did they do?” Kennedy asked in a low tone.
+</p>
+
+<p>
+Fearfully, gripping the bars of the iron bed, as though they were some tangible
+support for her mind, she answered: “They would get together. ‘Now, all of
+you,’ they said, ‘unite yourselves in thought against our enemy, against
+Kennedy, that he must leave off persecuting us. He is ripe for destruction!’”
+</p>
+
+<p>
+Kennedy glanced sidewise at me, with a significant look.
+</p>
+
+<p>
+“God grant,” she implored, “that none haunt me for what I have done in my
+ignorance!”
+</p>
+
+<p>
+Just then the door opened and my messenger entered, accompanied by Dr. Vaughn.
+</p>
+
+<p>
+I had turned to catch the expression on Blair’s face just in time. It was a
+look of abject appeal.
+</p>
+
+<p>
+Before Dr. Vaughn could ask a question, or fairly take in the situation,
+Kennedy had faced him.
+</p>
+
+<p>
+“What was the purpose of all that elaborate mummery out at the Red Lodge?”
+asked Kennedy pointblank.
+</p>
+
+<p>
+I think I looked at Craig in no less amazement than Vaughn. In spite of the
+dramatic scenes through which we had passed, the spell of the occult had not
+fallen on him for an instant.
+</p>
+
+<p>
+“Mummery?” repeated Dr. Vaughn, bending his penetrating eyes on Kennedy, as if
+he would force him to betray himself first.
+</p>
+
+<p>
+“Yes,” reiterated Craig. “You know as well as I do that it has been said that
+it is a well-established fact that the world wants to be deceived and is
+willing to pay for the privilege.”
+</p>
+
+<p>
+Dr. Vaughn still gazed from one to the other of us defiantly.
+</p>
+
+<p>
+“You know what I mean,” persisted Kennedy, “the mumbo-jumbo—just as the Haitian
+obi man sticks pins in a doll or melts a wax figure of his enemy. That is
+supposed to be an outward sign. But back of this terrible power that people
+believe moves in darkness and mystery is something tangible—something real.”
+</p>
+
+<p>
+Dr. Vaughn looked up sharply at him, I think mistaking Kennedy’s meaning. If he
+did, all doubt that Kennedy attributed anything to the supernatural was removed
+as he went on: “At first I had no explanation of the curious events I have just
+witnessed, and the more I thought about them, the more obscure did they seem.
+</p>
+
+<p>
+“I have tried to reason the thing out,” he continued thoughtfully. “Did
+auto-suggestion, self-hypnotism explain what I have seen? Has Veda Blair been
+driven almost to death by her own fears only?”
+</p>
+
+<p>
+No one interrupted and he answered his own question. “Somehow the idea that it
+was purely fear that had driven her on did not satisfy me. As I said, I wanted
+something more tangible. I could not help thinking that it was not merely
+subjective. There was something objective, some force at work, something more
+than psychic in the result achieved by this criminal mental marauder, whoever
+it is.”
+</p>
+
+<p>
+I was following Kennedy’s reasoning now closely. As he proceeded, the point
+that he was making seemed more clear to me.
+</p>
+
+<p>
+Persons of a certain type of mind could be really mentally unbalanced by such
+methods which we had heard outlined, where the mere fact of another trying to
+exert power over them became known to them. They would, as a matter of fact,
+unbalance themselves, thinking about and fighting off imaginary terrors.
+</p>
+
+<p>
+Such people, I could readily see, might be quickly controlled, and in the wake
+of such control would follow stifled love, wrecked homes, ruined fortunes,
+suicide and even death.
+</p>
+
+<p>
+Dr. Vaughn leaned forward critically. “What did you conclude, then, was the
+explanation of what you saw last night?” he asked sharply.
+</p>
+
+<p>
+Kennedy met his question squarely, without flinching. “It looks to me,” he
+replied quietly, “like a sort of hystero-epilepsy. It is well known, I believe,
+to demonologists—those who have studied this sort of thing. They have
+recognized the contortions, the screams, the wild, blasphemous talk, the
+cataleptic rigidity. They are epileptiform.”
+</p>
+
+<p>
+Vaughn said nothing, but continued to weigh Kennedy as if in a balance. I, who
+knew him, knew that it would take a greater than Vaughn to find him wanting,
+once Kennedy chose to speak. As for Vaughn, was he trying to hide behind some
+technicality in medical ethics?
+</p>
+
+<p>
+“Dr. Vaughn,” continued Craig, as if goading him to the point of breaking down
+his calm silence, “you are specialist enough to know these things as well,
+better than I do. You must know that epilepsy is one of the most peculiar
+diseases.
+</p>
+
+<p>
+“The victim may be in good physical condition, apparently. In fact, some hardly
+know that they have it. But it is something more than merely the fits. Always
+there is something wrong mentally. It is not the motor disturbance so much as
+the disturbance of consciousness.”
+</p>
+
+<p>
+Kennedy was talking slowly, deliberately, so that none could drop a link in the
+reasoning.
+</p>
+
+<p>
+“Perhaps one in ten epileptics has insane periods, more or less,” he went on,
+“and there is no more dangerous form of insanity. Self-consciousness is lost,
+and in this state of automatism the worst of crimes have been committed without
+the subsequent knowledge of the patient. In that state they are no more
+responsible than are the actors in one’s dreams.”
+</p>
+
+<p>
+The hospital physician entered, accompanied by Craig’s messenger, breathless.
+Craig almost seized the package from his hands and broke the seal.
+</p>
+
+<p>
+“Ah—this is what I wanted,” he exclaimed, with an air of relief, forgetting for
+the time the exposition of the case that he was engaged in. “Here I have some
+anti-crotalus venine, of Drs. Flexner and Noguchi. Fortunately, in the city it
+is within easy reach.”
+</p>
+
+<p>
+Quickly, with the aid of the physician he injected it into Veda’s arm.
+</p>
+
+<p>
+“Of all substances in nature,” he remarked, still at work over the unfortunate
+woman, “none is so little known as the venom of serpents.”
+</p>
+
+<p>
+It was a startling idea which the sentence had raised in my mind. All at once I
+recalled the first remark of Seward Blair, in which he had repeated the
+password that had admitted us into the Red Lodge—“the Serpent’s Tooth.” Could
+it have been that she had really been bitten at some of the orgies by the
+serpent which they worshiped hideously hissing in its cage? I was sure that, at
+least until they were compelled, none would say anything about it. Was that the
+interpretation of the almost hypnotized look on Blair’s face?
+</p>
+
+<p>
+“We know next to nothing of the composition of the protein bodies in the venoms
+which have such terrific, quick physiological effects,” Kennedy was saying.
+“They have been studied, it is true, but we cannot really say that they are
+understood—or even that there are any adequate tests by which they can be
+recognized. The fact is, that snake venoms are about the safest of poisons for
+the criminal.”
+</p>
+
+<p>
+Kennedy had scarcely propounded this startling idea when a car was heard
+outside. The Rapports had arrived, with the officer I had sent after them,
+protesting and threatening.
+</p>
+
+<p>
+They quieted down a bit as they entered, and after a quick glance around saw
+who was present.
+</p>
+
+<p>
+Professor Rapport gave one glance at the victim lying exhausted on the bed,
+then drew back, melodramatically, and cried, “The Serpent—the mark of the
+serpent!”
+</p>
+
+<p>
+For a moment Kennedy gazed full in the eyes of them all.
+</p>
+
+<p>
+“<i>Was</i> it a snake bite?” he asked slowly, then, turning to Mrs. Blair,
+after a quick glance, he went on rapidly, “The first thing to ascertain is
+whether the mark consists of two isolated punctures, from the poison-conducting
+teeth or fangs of the snake, which are constructed like a hypodermic needle.”
+</p>
+
+<p>
+The hospital physician had bent over her at the words, and before Kennedy could
+go on interrupted: “This was not a snake bite; it was more likely from an
+all-glass hypodermic syringe with a platinum-iridium needle.”
+</p>
+
+<p>
+Professor Rapport, priest of the Devil, advanced a step menacingly toward
+Kennedy. “Remember,” he said in a low, angry tone, “remember—you are pledged to
+keep the secrets of the Red Lodge!”
+</p>
+
+<p>
+Craig brushed aside the sophistry with a sentence. “I do not recognize any
+secrets that I have to keep about the meeting this afternoon to which you
+summoned the Blairs and Mrs. Langhorne, according to reports from the shadows I
+had placed on Mrs. Langhorne and Dr. Vaughn.”
+</p>
+
+<p>
+If there is such a thing as the evil eye, Rapport’s must have been a pair of
+them, as he realized that Kennedy had resorted to the simple devices of
+shadowing the devotees.
+</p>
+
+<p>
+A cry, almost a shriek, startled us. Kennedy’s encounter with Rapport had had
+an effect which none of us had considered. The step or two in advance which the
+prophet had taken had brought him into the line of vision of the still
+half-stupefied Veda lying back of Kennedy on the hospital cot.
+</p>
+
+<p>
+The mere sight of him, the sound of his voice and the mention of the Red Lodge
+had been sufficient to penetrate that stupor. She was sitting bolt upright, a
+ghastly, trembling specter. Slowly a smile seemed to creep over the cruel face
+of the mystic. Was it not a recognition of his hypnotic power?
+</p>
+
+<p>
+Kennedy turned and laid a gentle hand on the quaking convulsed figure of the
+woman. One could feel the electric tension in the air, the battle of two powers
+for good or evil. Which would win—the old fascination of the occult or the new
+power of science?
+</p>
+
+<p>
+It was a dramatic moment. Yet not so dramatic as the outcome. To my surprise,
+neither won.
+</p>
+
+<p>
+Suddenly she caught sight of her husband. Her face changed. All the prehistoric
+jealousy of which woman is capable seemed to blaze forth.
+</p>
+
+<p>
+“I will defend myself!” she cried. “I will fight back! She shall not win—she
+shall not have you—no—she shall not—never!”
+</p>
+
+<p>
+I recalled the strained feeling between the two women that I had noticed in the
+cab. Was it Mrs. Langhorne who had been the disturbing influence, whose power
+she feared, over herself and over her husband?
+</p>
+
+<p>
+Rapport had fallen back a step, but not from the mind of Kennedy.
+</p>
+
+<p>
+“Here,” challenged Craig, facing the group and drawing from his pocket the
+glass ampoule, “I picked this up at the Red Lodge last night.”
+</p>
+
+<p>
+He held it out in his hand before the Rapports so that they could not help but
+see it. Were they merely good actors? They betrayed nothing, at least by face
+or action.
+</p>
+
+<p>
+“It is crotalin,” he announced, “the venom of the rattlesnake—crotalus
+horridus. It has been noticed that persons suffering from certain diseases of
+which epilepsy is one, after having been bitten by a rattlesnake, if they
+recover from the snake bite, are cured of the disease.”
+</p>
+
+<p>
+Kennedy was forging straight ahead now in his exposure. “Crotalin,” he
+continued, “is one of the new drugs used in the treatment of epilepsy. But it
+is a powerful two-edged instrument. Some one who knew the drug, who perhaps had
+used it, has tried an artificial bite of a rattler on Veda Blair, not for
+epilepsy, but for another, diabolical purpose, thinking to cover up the crime,
+either as the result of the so-called death thought of the Lodge or as the bite
+of the real rattler at the Lodge.”
+</p>
+
+<p>
+Kennedy had at last got under Dr. Vaughn’s guard. All his reticence was gone.
+</p>
+
+<p>
+“I joined the cult,” he confessed. “I did it in order to observe and treat one
+of my patients for epilepsy. I justified myself. I said, ‘I will be the
+exposer, not the accomplice, of this modern Satanism.’ I joined it and—”
+</p>
+
+<p>
+“There is no use trying to shield anyone, Vaughn,” rapped out Kennedy, scarcely
+taking time to listen. “An epileptic of the most dangerous criminal type has
+arranged this whole elaborate setting as a plot to get rid of the wife who
+brought him his fortune and now stands in the way of his unholy love of Mrs.
+Langhorne. He used you to get the poison with which you treated him. He used
+the Rapports with money to play on her mysticism by their so-called death
+thought, while he watched his opportunity to inject the fatal crotalin.”
+</p>
+
+<p>
+Craig faced the criminal, whose eyes now showed more plainly than words his
+deranged mental condition, and in a low tone added, “The Devil <i>is</i> in
+you, Seward Blair!”

+THE “HAPPY DUST”</h2>
+
+<p>
+Veda Blair’s rescue from the strange use that was made of the venom came at a
+time when the city was aroused as it never had been before over the nation-wide
+agitation against drugs.
+</p>
+
+<p>
+Already, it will be recalled, Kennedy and I had had some recent experience with
+dope fiends of various kinds, but this case I set down because it drew us more
+intimately into the crusade.
+</p>
+
+<p>
+“I’ve called on you, Professor Kennedy, to see if I can’t interest you in the
+campaign I am planning against drugs.”
+</p>
+
+<p>
+Mrs. Claydon Sutphen, social leader and suffragist, had scarcely more than
+introduced herself when she launched earnestly into the reason for her visit to
+us.
+</p>
+
+<p>
+“You don’t realize it, perhaps,” she continued rapidly, “but very often a
+little silver bottle of tablets is as much a necessary to some women of the
+smart set as cosmetics.”
+</p>
+
+<p>
+“I’ve heard of such cases,” nodded Craig encouragingly.
+</p>
+
+<p>
+“Well, you see I became interested in the subject,” she added, “when I saw some
+of my own friends going down. That’s how I came to plan the campaign in the
+first place.”
+</p>
+
+<p>
+She paused, evidently nervous. “I’ve been threatened, too,” she went on, “but
+I’m not going to give up the fight. People think that drugs are a curse only to
+the underworld, but they have no idea what inroads the habit has made in the
+upper world, too. Oh, it is awful!” she exclaimed.
+</p>
+
+<p>
+Suddenly, she leaned over and whispered, “Why, there’s my own sister, Mrs.
+Garrett. She began taking drugs after an operation, and now they have a
+terrible hold on her. I needn’t try to conceal anything. It’s all been
+published in the papers—everybody knows it. Think of it—divorced, disgraced,
+all through these cursed drugs! Dr. Coleman, our family physician, has done
+everything known to break up the habit, but he hasn’t succeeded.”
+</p>
+
+<p>
+Dr. Coleman, I knew, was a famous society physician. If he had failed, I
+wondered why she thought a detective might succeed. But it was evidently
+another purpose she had in mind in introducing the subject.
+</p>
+
+<p>
+“So you can understand what it all means to me, personally,” she resumed, with
+a sigh. “I’ve studied the thing—I’ve been forced to study it. Why, now the
+exploiters are even making drug fiends of mere—children!”
+</p>
+
+<p>
+Mrs. Sutphen spread out a crumpled sheet of note paper before us on which was
+written something in a trembling scrawl. “For instance, here’s a letter I
+received only yesterday.”
+</p>
+
+<p>
+Kennedy glanced over it carefully. It was signed “A Friend,” and read:
+</p>
+
+<p class="p2">
+“I have heard of your drug war in the newspapers and wish to help you, only I
+don’t dare to do so openly. But I can assure you that if you will investigate
+what I am about to tell you, you will soon be on the trail of those higher up
+in this terrible drug business. There is a little center of the traffic on West
+66th Street, just off Broadway. I cannot tell you more, but if you can
+investigate it, you will be doing more good than you can possibly realize now.
+There is one girl there, whom they call ‘Snowbird.’ If you could only get hold
+of her quietly and place her in a sanitarium you might save her yet.”
+</p>
+
+<p class="p2">
+Craig was more than ordinarily interested. “And the children—what did you mean
+by that?”
+</p>
+
+<p>
+“Why, it’s literally true,” asserted Mrs. Sutphen in a horrified tone. “Some of
+the victims are actually school children. Up there in 66th Street we have found
+a man named Armstrong, who seems to be very friendly with this young girl whom
+they call ‘Snowbird.’ Her real name, by the way, is Sawtelle, I believe. She
+can’t be over eighteen, a mere child, yet she’s a slave to the stuff.”
+</p>
+
+<p>
+“Oh, then you have actually already acted on the hint in the letter?” asked
+Craig.
+</p>
+
+<p>
+“Yes,” she replied, “I’ve had one of the agents of our Anti-Drug Society, a
+social worker, investigating the neighborhood.”
+</p>
+
+<p>
+Kennedy nodded for her to go on.
+</p>
+
+<p>
+“I’ve even investigated myself a little, and now I want to employ some one to
+break the thing up. My husband had heard of you and so here I am. Can you help
+me?”
+</p>
+
+<p>
+There was a note of appeal in her voice that was irresistible to a man who had
+the heart of Kennedy.
+</p>
+
+<p>
+“Tell me just what you have discovered so far,” he asked simply.
+</p>
+
+<p>
+“Well,” she replied slowly, “after my agent verified the contents of the
+letter, I watched until I saw this girl—she’s a mere child, as I said—going to
+a cabaret in the neighborhood. What struck me was that I saw her go in looking
+like a wreck and come out a beautiful creature, with bright eyes, flushed
+cheeks, almost youthful again. A most remarkable girl she is, too,” mused Mrs.
+Sutphen, “who always wears a white gown, white hat, white shoes and white
+stockings. It must be a mania with her.”
+</p>
+
+<p>
+Mrs. Sutphen seemed to have exhausted her small store of information, and as
+she rose to go Kennedy rose also. “I shall be glad to look into the case, Mrs.
+Sutphen,” he promised. “I’m sure there is something that can be done—there must
+be.”
+</p>
+
+<p>
+“Thank you, ever so much,” she murmured, as she paused at the door, something
+still on her mind. “And perhaps, too,” she added, “you may run across my
+sister, Mrs. Garrett.”
+</p>
+
+<p>
+“Indeed,” he assured her, “if there is anything I can possibly do that will
+assist you personally, I shall be only too happy to do it.”
+</p>
+
+<p>
+“Thank you again, ever so much,” she repeated with just a little choke in her
+voice.
+</p>
+
+<p>
+For several moments Kennedy sat contemplating the anonymous letter which she
+had left with him, studying both its contents and the handwriting.
+</p>
+
+<p>
+“We must go over the ground up there again,” he remarked finally. “Perhaps we
+can do better than Mrs. Sutphen and her drug investigator have done.”
+</p>
+
+<p>
+Half an hour later we had arrived and were sauntering along the street in
+question, walking slowly up and down in the now fast-gathering dusk. It was a
+typical cheap apartment block of variegated character, with people sitting idly
+on the narrow front steps and children spilling out into the roadway in
+imminent danger of their young lives from every passing automobile.
+</p>
+
+<p>
+On the crowded sidewalk a creation in white hurtled past us. One glance at the
+tense face in the flickering arc light was enough for Kennedy. He pulled my arm
+and we turned and followed at a safe distance.
+</p>
+
+<p>
+She looked like a girl who could not have been more than eighteen, if she was
+as old as that. She was pretty, too, but already her face was beginning to look
+old and worn from the use of drugs. It was unmistakable.
+</p>
+
+<p>
+In spite of the fact that she was hurrying, it was not difficult to follow her
+in the crowd, as she picked her way in and out, and finally turned into
+Broadway where the white lights were welcoming the night.
+</p>
+
+<p>
+Under the glare of a huge electric sign she stopped a moment, then entered one
+of the most notorious of the cabarets.
+</p>
+
+<p>
+We entered also at a discreet distance and sat down at a table.
+</p>
+
+<p>
+“Don’t look around, Walter,” whispered Craig, as the waiter took our order,
+“but to your right is Mrs. Sutphen.”
+</p>
+
+<p>
+If he had mentioned any other name in the world, I could not have been more
+surprised. I waited impatiently until I could pick her out from the corner of
+my eye. Sure enough, it was Mrs. Sutphen and another woman. What they were
+doing there I could not imagine, for neither had the look of habitues of such a
+place.
+</p>
+
+<p>
+I followed Kennedy’s eye and found that he was gazing furtively at a flashily
+dressed young man who was sitting alone at the far end in a sort of booth
+upholstered in leather.
+</p>
+
+<p>
+The girl in white, whom I was now sure was Miss Sawtelle, went over and greeted
+him. It was too far to see just what happened, but the young woman after
+sitting down rose and left almost immediately. As nearly as I could make out,
+she had got something from him which she had dropped into her handbag and was
+now hugging the handbag close to herself almost as if it were gold.
+</p>
+
+<p>
+We sat for a few minutes debating just what to do, when Mrs. Sutphen and her
+friend rose. As she passed out, a quick, covert glance told us to follow. We
+did so and the two turned into Broadway.
+</p>
+
+<p>
+“Let me present you to Miss McCann,” introduced Mrs. Sutphen as we caught up
+with them. “Miss McCann is a social worker and trained investigator whom I’m
+employing.”
+</p>
+
+<p>
+We bowed, but before we could ask a question, Mrs. Sutphen cried excitedly: “I
+think I have a clue, anyway. We’ve traced the source of the drugs at least as
+far as that young fellow, ‘Whitecap,’ whom you saw in there.”
+</p>
+
+<p>
+I had not recognized his face, although I had undoubtedly seen pictures of him
+before. But no sooner had I heard the name than I recognized it as that of one
+of the most notorious gang leaders on the West Side.
+</p>
+
+<p>
+Not only that, but Whitecap’s gang played an important part in local politics.
+There was scarcely a form of crime or vice to which Whitecap and his followers
+could not turn a skilled hand, whether it was swinging an election, running a
+gambling club, or dispensing “dope.”
+</p>
+
+<p>
+“You see,” she explained, “even before I saw you, my suspicions were aroused
+and I determined to obtain some of the stuff they are using up here, if
+possible. I realized it would be useless for me to try to get it myself, so I
+got Miss McCann from the Neighborhood House to try it. She got it and has
+turned the bottle over to me.”
+</p>
+
+<p>
+“May I see it?” asked Craig eagerly.
+</p>
+
+<p>
+Mrs. Sutphen reached hastily into her handbag, drew forth a small brown glass
+bottle and handed it to him. Craig retreated into one of the less dark side
+streets. There he pulled out the paraffinned cork from the bottle, picked out a
+piece of cotton stuffed in the neck of the bottle and poured out some flat
+tablets that showed a glistening white in the palm of his hand. For an instant
+he regarded them.
+</p>
+
+<p>
+“I may keep these?” he asked.
+</p>
+
+<p>
+“Certainly,” replied Mrs. Sutphen. “That’s what I had Miss McCann get them
+for.”
+</p>
+
+<p>
+Kennedy dropped the bottle into his pocket.
+</p>
+
+<p>
+“So that was the gang leader, ‘Whitecap,’” he remarked as we turned again to
+Broadway.
+</p>
+
+<p>
+“Yes,” replied Mrs. Sutphen. “At certain hours, I believe he can be found at
+that cabaret selling this stuff, whatever it is, to anyone who comes properly
+introduced. The thing seems to be so open and notorious that it amounts to a
+scandal.”
+</p>
+
+<p>
+We parted a moment later, Mrs. Sutphen and Miss McCann to go to the settlement
+house, Craig and I to continue our investigations.
+</p>
+
+<p>
+“First of all, Walter,” he said as we swung aboard an uptown car, “I want to
+stop at the laboratory.”
+</p>
+
+<p>
+In his den, which had been the scene of so many triumphs, Kennedy began a hasty
+examination of the tablets, powdering one and testing it with one chemical
+after another.
+</p>
+
+<p>
+“What are they?” I asked at length when he seemed to have found the right
+reaction which gave him the clue.
+</p>
+
+<p>
+“Happy dust,” he answered briefly.
+</p>
+
+<p>
+“Happy dust?” I repeated, looking at him a moment in doubt as to whether he was
+joking or serious. “What is that?”
+</p>
+
+<p>
+“The Tenderloin name for heroin—a comparatively new derivative of morphine. It
+is really morphine treated with acetic acid which renders it more powerful than
+morphine alone.”
+</p>
+
+<p>
+“How do they take them? What’s the effect?” I asked.
+</p>
+
+<p>
+“The person who uses heroin usually powders the tablets and snuffs the powder
+up the nose,” he answered. “In a short time, perhaps only two or three weeks,
+one can become a confirmed victim of ‘happy dust.’ And while one is under its
+influence he is morally, physically and mentally irresponsible.”
+</p>
+
+<p>
+Kennedy was putting away the paraphernalia he had used, meanwhile talking about
+the drug. “One of the worst aspects of it, too,” he continued, “is the desire
+of the user to share his experience with some one else. This passing on of the
+habit, which seems to be one of the strongest desires of the drug fiend, makes
+him even more dangerous to society than he would otherwise be. It makes it
+harder for anyone once addicted to a drug to shake it off, for his friends will
+give him no chance. The only thing to do is to get the victim out of his
+environment and into an entirely new scene.”
+</p>
+
+<p>
+The laboratory table cleared again, Kennedy had dropped into a deep study.
+</p>
+
+<p>
+“Now, why was Mrs. Sutphen there?” he asked aloud. “I can’t think it was solely
+through her interest for that girl they call Snowbird. She was interested in
+her, but she made no attempt to interfere or to follow her. No, there must have
+been another reason.”
+</p>
+
+<p>
+“You don’t think she’s a dope fiend herself, do you?” I asked hurriedly.
+</p>
+
+<p>
+Kennedy smiled. “Hardly, Walter. If she has any obsession on the subject, it is
+more likely to lead her to actual fanaticism against all stimulants and
+narcotics and everything connected with them. No, you might possibly persuade
+me that two and two equal five—but not seventeen. It’s not very late. I think
+we might make another visit to that cabaret and see whether the same thing is
+going on yet.”

+THE BINET TEST</h2>
+
+<p>
+We rode downtown again and again sauntered in, this time with the theater
+crowd. Our first visit had been so quiet and unostentatious that the second
+attracted no attention or comment from the waiters, or anyone else.
+</p>
+
+<p>
+As we sat down we glanced over, and there in his corner still was Whitecap.
+Apparently his supply of the dope was inexhaustible, for he was still
+dispensing it. As we watched the tenderloin habitues come and go, I came soon
+to recognize the signs by the mere look on the face—the pasty skin, the vacant
+eye, the nervous quiver of the muscles as though every organ and every nerve
+were crying out for more of the favorite nepenthe. Time and again I noticed the
+victims as they sat at the tables, growing more and more haggard and worn,
+until they could stand it no longer. Then they would retire, sometimes after a
+visit across the floor to Whitecap, more often directly, for they had stocked
+themselves up with the drug evidently after the first visit to him. But always
+they would come back, changed in appearance, with what seemed to be a new lease
+of life, but nevertheless still as recognizable as drug victims.
+</p>
+
+<p>
+It was not long, as we waited, before another woman, older than Miss Sawtelle,
+but dressed in an extreme fashion, hurried into the cabaret and with scarcely a
+look to right or left went directly to Whitecap’s corner. I noticed that she,
+too, had the look.
+</p>
+
+<p>
+There was a surreptitious passing of a bottle in exchange for a treasury note,
+and she dropped into the seat beside him.
+</p>
+
+<p>
+Before he could interfere, she had opened the bottle, crushed a tablet or two
+in a napkin, and was holding it to her face as though breathing the most
+exquisite perfume. With one quick inspiration of her breath after another, she
+was snuffing the powder up her nose.
+</p>
+
+<p>
+Whitecap with an angry gesture pulled the napkin from her face, and one could
+fancy his snarl under his breath, “Say—do you want to get me in wrong here?”
+</p>
+
+<p>
+But it was too late. Some at least of the happy dust had taken effect, at least
+enough to relieve the terrible pangs she must have been suffering.
+</p>
+
+<p>
+As she rose and retired, with a hasty apology to Whitecap for her indiscretion,
+Kennedy turned to me and exclaimed, “Think of it. The deadliest of all habits
+is the simplest. No hypodermic; no pipe; no paraphernalia of any kind. It’s
+terrible.”
+</p>
+
+<p>
+She returned to sit down and enjoy herself, careful not to obtrude herself on
+Whitecap lest he might become angry at the mere sight of her and treasure his
+anger up against the next time when she would need the drug.
+</p>
+
+<p>
+Already there was the most marvelous change in her. She seemed captivated by
+the music, the dancing, the life which a few moments before she had totally
+disregarded.
+</p>
+
+<p>
+She was seated alone, not far from us, and as she glanced about Kennedy caught
+her eye. She allowed her gaze to rest on us for a moment, the signal for a mild
+flirtation which ended in our exchange of tables and we found ourselves
+opposite the drug fiend, who was following up the taking of the dope by a
+thin-stemmed glass of a liqueur.
+</p>
+
+<p>
+I do not recall the conversation, but it was one of those inconsequential talks
+that Bohemians consider so brilliant and everybody else so vapid. As we skimmed
+from one subject to another, treating the big facts of life as if they were
+mere incidents and the little as if they overshadowed all else, I could see
+that Craig, who had a faculty of probing into the very soul of anyone, when he
+chose, was gradually leading around to a subject which I knew he wanted, above
+all others, to discuss.
+</p>
+
+<p>
+It was not long before, as the most natural remark in the world following
+something he had made her say, just as a clever prestidigitator forces a card,
+he asked, “What was it I saw you snuffing over in the booth—happy dust?”
+</p>
+
+<p>
+She did not even take the trouble to deny it, but nodded a brazen “Yes.” “How
+did you come to use it first?” he asked, careful not to give offense in either
+tone or manner.
+</p>
+
+<p>
+“The usual way, I suppose,” she replied with a laugh that sounded harsh and
+grating. “I was ill and I found out what it was the doctor was giving me.”
+</p>
+
+<p>
+“And then?”
+</p>
+
+<p>
+“Oh, I thought I would use it only as long as it served my purpose and, when
+that was over, give it up.”
+</p>
+
+<p>
+“But—?” prompted Craig hypnotically.
+</p>
+
+<p>
+“Instead, I was soon using six, eight, ten tablets of heroin a day. I found
+that I needed that amount in order to live. Then it went up by leaps to twenty,
+thirty, forty.”
+</p>
+
+<p>
+“Suppose you couldn’t get it, what then?”
+</p>
+
+<p>
+“Couldn’t get it?” she repeated with an unspeakable horror. “Once I thought I’d
+try to stop. But my heart skipped beats; then it seemed to pound away, as if
+trying to break through my ribs. I don’t think heroin is like other drugs. When
+one has her ‘coke’—that’s cocaine—taken away, she feels like a rag. Fill her up
+and she can do anything again. But, heroin—I think one might murder to get it!”
+</p>
+
+<p>
+The expression on the woman’s face was almost tragic. I verily believe that she
+meant it.
+</p>
+
+<p>
+“Why,” she cried, “if anyone had told me a year ago that the time would ever
+come when I would value some tiny white tablets above anything else in the
+world, yes, and even above my immortal soul, I would have thought him a
+lunatic.”
+</p>
+
+<p>
+It was getting late, and as the woman showed no disposition to leave, Kennedy
+and I excused ourselves.
+</p>
+
+<p>
+Outside Craig looked at me keenly. “Can you guess who that was?”
+</p>
+
+<p>
+“Although she didn’t tell us her name,” I replied, “I am morally certain that
+it was Mrs. Garrett.”
+</p>
+
+<p>
+“Precisely,” he answered, “and what a shame, too, for she must evidently once
+have been a woman of great education and refinement.”
+</p>
+
+<p>
+He shook his head sadly. “Walter, there isn’t likely to be anything that we can
+do for some hours now. I have a little experiment I’d like to make. Suppose you
+publish for me a story in the <i>Star</i> about the campaign against drugs.
+Tell about what we have seen to-night, mention the cabaret by indirection and
+Whitecap directly. Then we can sit back and see what happens. We’ve got to
+throw a scare into them somehow, if we are going to smoke out anyone higher up
+than Whitecap. But you’ll have to be careful, for if they suspect us our
+usefulness in the case will be over.”
+</p>
+
+<p>
+Together, Kennedy and I worked over our story far into the night down at the
+<i>Star</i> office, and the following day waited to see whether anything came
+of it.
+</p>
+
+<p>
+It was with a great deal of interest tempered by fear that we dropped into the
+cabaret the following evening. Fortunately no one suspected us. In fact, having
+been there the night before, we had established ourselves, as it were, and were
+welcomed as old patrons and good spenders.
+</p>
+
+<p>
+I noticed, however, that Whitecap was not there. The story had been read by
+such of the dope fiends as had not fallen too far to keep abreast of the times
+and these and the waiters were busy quietly warning off a line of haggard-eyed,
+disappointed patrons who came around, as usual.
+</p>
+
+<p>
+Some of them were so obviously dependent on Whitecap that I almost regretted
+having written the story, for they must have been suffering the tortures of the
+damned.
+</p>
+
+<p>
+It was in the midst of a reverie of this sort that a low exclamation from
+Kennedy recalled my attention. There was Snowbird with a man considerably older
+than herself. They had just come in and were looking about frantically for
+Whitecap. But Whitecap had been too frightened by the story in the <i>Star</i>
+to sell any more of the magic happy dust openly in the cabaret, at least.
+</p>
+
+<p>
+The pair, nerve-racked and exhausted, sat down mournfully in a seat near us,
+and as they talked earnestly in low tones we had an excellent opportunity for
+studying Armstrong for the first time.
+</p>
+
+<p>
+He was not a bad-looking man, or even a weak one. In back of the dissipation of
+the drugs one fancied he could read the story of a brilliant life wrecked. But
+there was little left to admire or respect. As the couple talked earnestly, the
+one so old, the other so young in vice, I had to keep a tight rein on myself to
+prevent my sympathy for the wretched girl getting the better of common sense
+and kicking the older man out of doors.
+</p>
+
+<p>
+Finally Armstrong rose to go, with a final imploring glance from the girl.
+Obviously she had persuaded him to forage about to secure the heroin, by hook
+or crook, now that the accustomed source of supply was cut off so suddenly.
+</p>
+
+<p>
+It was also really our first chance to study the girl carefully under the
+light, for her entrance and exit the night before had been so hurried that we
+had seen comparatively little of her. Craig was watching her narrowly. Not only
+were the effects of the drug plainly evident on her face, but it was apparent
+that the snuffing the powdered tablets was destroying the bones in her nose,
+through shrinkage of the blood vessels, as well as undermining the nervous
+system and causing the brain to totter.
+</p>
+
+<p>
+I was wondering whether Armstrong knew of any depot for the secret distribution
+of the drug. I could not believe that Whitecap was either the chief distributer
+or the financial head of the illegal traffic. I wondered who indeed was the man
+higher up. Was he an importer of the drug, or was he the representative of some
+chemical company not averse to making an illegal dollar now and then by
+dragging down his fellow man?
+</p>
+
+<p>
+Kennedy and I were trying to act as if we were enjoying the cabaret show and
+not too much interested in the little drama that was being acted before us. I
+think little Miss Sawtelle noticed, however, that we were looking often her
+way. I was amazed, too, on studying her more closely to find that there was
+something indefinably queer about her, aside from the marked effect of the
+drugs she had been taking. What it was I was at a loss to determine, but I felt
+sure from the expression on Kennedy’s face that he had noticed it also.
+</p>
+
+<p>
+I was on the point of asking him if he, too, observed anything queer in the
+girl, when Armstrong hurried in and handed her a small package, then almost
+without a word stalked out again, evidently as much to Snowbird’s surprise as
+to our own.
+</p>
+
+<p>
+She had literally seized the package, as though she were drowning and grasping
+at a life buoy. Even the surprise at his hasty departure could not prevent her,
+however, from literally tearing the wrapper off, and in the sheltering shadow
+of the table cloth pouring forth the little white pellets in her lap, counting
+them as a miser counts his gold,
+</p>
+
+<p>
+“The old thief!” she exclaimed aloud. “He’s held out twenty-five!”
+</p>
+
+<p>
+I don’t know which it was that amazed me most, the almost childish petulance
+and ungovernable temper of the girl which made her cry out in spite of her
+surroundings and the circumstances, or the petty rapacity of the man who could
+stoop to such a low level as to rob her in this seeming underhand manner.
+</p>
+
+<p>
+There was no time for useless repining now. The call of outraged nature for its
+daily and hourly quota of poison was too imperative. She dumped the pellets
+back into the bottle hastily, and disappeared.
+</p>
+
+<p>
+When she came back, it was with that expression I had come to know so well. At
+least for a few hours there was a respite for her from the terrific pangs she
+had been suffering. She was almost happy, smiling. Even that false happiness, I
+felt, was superior to Armstrong’s moral sense blunted by drugs. I had begun to
+realize how lying, stealing, crimes of all sorts might be laid at the door of
+this great evil.
+</p>
+
+<p>
+In her haste to get where she could snuff the heroin she had forgotten a light
+wrap lying on her chair. As she returned for it, it fell to the floor.
+Instantly Kennedy was on his feet, bending over to pick it up.
+</p>
+
+<p>
+She thanked him, and the smile lingered a moment on her face. It was enough. It
+gave Kennedy the chance to pursue a conversation, and in the free and easy
+atmosphere of the cabaret to invite her to sit over at our table.
+</p>
+
+<p>
+At least all her nervousness was gone and she chatted vivaciously. Kennedy said
+little. He was too busy watching her. It was quite the opposite of the case of
+Mrs. Garrett. Yet I was at a loss to define what it was that I sensed.
+</p>
+
+<p>
+Still the minutes sped past and we seemed to be getting on famously. Unlike his
+action in the case of the older woman where he had been sounding the depths of
+her heart and mind, in this case his idea seemed to be to allow the childish
+prattle to come out and perhaps explain itself.
+</p>
+
+<p>
+However, at the end of half an hour when we seemed to be getting no further
+along, Kennedy did not protest at her desire to leave us, “to keep a date,” as
+she expressed it.
+</p>
+
+<p>
+“Waiter, the check, please,” ordered Kennedy leisurely.
+</p>
+
+<p>
+When he received it, he seemed to be in no great hurry to pay it, but went over
+one item after another, then added up the footing again.
+</p>
+
+<p>
+“Strange how some of these waiters grow rich?” Craig remarked finally with a
+gay smile.
+</p>
+
+<p>
+The idea of waiters and money quickly brought some petty reminiscences to her
+mind. While she was still talking, Craig casually pulled a pencil out of his
+pocket and scribbled some figures on the back of the waiter’s check.
+</p>
+
+<p>
+From where I was sitting beside him, I could see that he had written some
+figures similar to the following:
+</p>
+
+<p class="letter">
+5183<br/>
+47395<br/>
+654726<br/>
+2964375<br/>
+47293815<br/>
+924738651<br/>
+2146073859
+</p>
+
+<p>
+“Here’s a stunt,” he remarked, breaking into the conversation at a convenient
+point. “Can you repeat these numbers after me?”
+</p>
+
+<p>
+Without waiting for her to make excuse, he said quickly “5183.” “5183,” she
+repeated mechanically.
+</p>
+
+<p>
+“47395,” came in rapid succession, to which she replied, perhaps a little
+slower than before,
+</p>
+
+<p>
+“47395.”
+</p>
+
+<p>
+“Now, 654726,” he said.
+</p>
+
+<p>
+“654726,” she repeated, I thought with some hesitation.
+</p>
+
+<p>
+“Again, 2964375,” he shot out.
+</p>
+
+<p>
+“269,” she hesitated, “73—” she stopped.
+</p>
+
+<p>
+It was evident that she had reached the limit.
+</p>
+
+<p>
+Kennedy smiled, paid the check and we parted at the door.
+</p>
+
+<p>
+“What was all that rigmarole?” I inquired as the white figure disappeared down
+the street.
+</p>
+
+<p>
+“Part of the Binet test, seeing how many digits one can remember. An adult
+ought to remember from eight to ten, in any order. But she has the mentality of
+a child. That is the queer thing about her. Chronologically she may be eighteen
+years or so old. Mentally she is scarcely more than eight. Mrs. Sutphen was
+right. They have made a fiend out of a mere child—a defective who never had a
+chance against them.”

+THE LIE DETECTOR</h2>
+
+<p>
+As the horror of it all dawned on me, I hated Armstrong worse than ever, hated
+Whitecap, hated the man higher up, whoever he might be, who was enriching
+himself out of the defective, as well as the weakling, and the vicious—all
+three typified by Snowbird, Armstrong and Whitecap.
+</p>
+
+<p>
+Having no other place to go, pending further developments of the publicity we
+had given the drug war in the <i>Star</i>, Kennedy and I decided on a walk home
+in the bracing night air.
+</p>
+
+<p>
+We had scarcely entered the apartment when the hall boy called to us
+frantically: “Some one’s been trying to get you all over town, Professor
+Kennedy. Here’s the message. I wrote it down. An attempt has been made to
+poison Mrs. Sutphen. They said at the other end of the line that you’d know.”
+</p>
+
+<p>
+We faced each other aghast.
+</p>
+
+<p>
+“My God!” exclaimed Kennedy. “Has that been the effect of our story, Walter?
+Instead of smoking out anyone—we’ve almost killed some one.”
+</p>
+
+<p>
+As fast as a cab could whisk us around to Mrs. Sutphen’s we hurried.
+</p>
+
+<p>
+“I warned her that if she mixed up in any such fight as this she might expect
+almost anything,” remarked Mr. Sutphen nervously, as he met us in the reception
+room. “She’s all right, now, I guess, but if it hadn’t been for the prompt work
+of the ambulance surgeon I sent for, Dr. Coleman says she would have died in
+fifteen minutes.”
+</p>
+
+<p>
+“How did it happen?” asked Craig.
+</p>
+
+<p>
+“Why, she usually drinks a glass of vichy and milk before retiring,” replied
+Mr. Sutphen. “We don’t know yet whether it was the vichy or the milk that was
+poisoned, but Dr. Coleman thinks it was chloral in one or the other, and so did
+the ambulance surgeon. I tell you I was scared. I tried to get Coleman, but he
+was out on a case, and I happened to think of the hospitals as probably the
+quickest. Dr. Coleman came in just as the young surgeon was bringing her
+around. He—oh, here he is now.”
+</p>
+
+<p>
+The famous doctor was just coming downstairs. He saw us, but, I suppose,
+inasmuch as we did not belong to the Sutphen and Coleman set, ignored us. “Mrs.
+Sutphen will be all right now,” he said reassuringly as he drew on his gloves.
+“The nurse has arrived, and I have given her instructions what to do. And, by
+the way, my dear Sutphen, I should advise you to deal firmly with her in that
+matter about which her name is appearing in the papers. Women nowadays don’t
+seem to realize the dangers they run in mixing in in all these reforms. I have
+ordered an analysis of both the milk and vichy, but that will do little good
+unless we can find out who poisoned it. And there are so many chances for
+things like that, life is so complex nowadays—”
+</p>
+
+<p>
+He passed out with scarcely a nod at us. Kennedy did not attempt to question
+him. He was thinking rapidly.
+</p>
+
+<p>
+“Walter, we have no time to lose,” he exclaimed, seizing a telephone that stood
+on a stand near by. “This is the time for action. Hello—Police Headquarters,
+First Deputy O’Connor, please.”
+</p>
+
+<p>
+As Kennedy waited I tried to figure out how it could have happened. I wondered
+whether it might not have been Mrs. Garrett. Would she stop at anything if she
+feared the loss of her favorite drug? But then there were so many others and so
+many ways of “getting” anybody who interfered with the drug traffic that it
+seemed impossible to figure it out by pure deduction.
+</p>
+
+<p>
+“Hello, O’Connor,” I heard Kennedy say; “you read that story in the <i>Star</i>
+this morning about the drug fiends at that Broadway cabaret? Yes? Well, Jameson
+and I wrote it. It’s part of the drug war that Mrs. Sutphen has been waging.
+O’Connor, she’s been poisoned—oh, no—she’s all right now. But I want you to
+send out and arrest Whitecap and that fellow Armstrong immediately. I’m going
+to put them through a scientific third degree up in the laboratory to-night.
+Thank you. No—no matter how late it is, bring them up.”
+</p>
+
+<p>
+Dr. Coleman had gone long since, Mr. Sutphen had absolutely no interest further
+than the recovery of Mrs. Sutphen just now, and Mrs. Sutphen was resting
+quietly and could not be seen. Accordingly Kennedy and I hastened up to the
+laboratory to wait until O’Connor could “deliver the goods.”
+</p>
+
+<p>
+It was not long before one of O’Connor’s men came in with Whitecap.
+</p>
+
+<p>
+“While we’re waiting,” said Craig, “I wish you would just try this little
+cut-out puzzle.”
+</p>
+
+<p>
+I don’t know what Whitecap thought, but I know I looked at Craig’s invitation
+to “play blocks” as a joke scarcely higher in order than the number repetition
+of Snowbird. Whitecap did it, however, sullenly, and under compulsion, in, I
+should say about two minutes.
+</p>
+
+<p>
+“I have Armstrong here myself,” called out the voice of our old friend
+O’Connor, as he burst into the room.
+</p>
+
+<p>
+“Good!” exclaimed Kennedy. “I shall be ready for him in just a second. Have
+Whitecap held here in the anteroom while you bring Armstrong into the
+laboratory. By the way, Walter, that was another of the Binet tests, putting a
+man at solving puzzles. It involves reflective judgment, one of the factors in
+executive ability. If Whitecap had been defective, it would have taken him five
+minutes to do that puzzle, if at all. So you see he is not in the class with
+Miss Sawtelle. The test shows him to be shrewd. He doesn’t even touch his own
+dope. Now for Armstrong.”
+</p>
+
+<p>
+I knew enough of the underworld to set Whitecap down, however, as a
+“lobbygow”—an agent for some one higher up, recruiting both the gangs and the
+ranks of street women.
+</p>
+
+<p>
+Before us, as O’Connor led in Armstrong, was a little machine with a big black
+cylinder. By means of wires and electrodes Kennedy attached it to Armstrong’s
+chest.
+</p>
+
+<p>
+“Now, Armstrong,” he began in an even tone, “I want you to tell the truth—the
+whole truth. You have been getting heroin tablets from Whitecap.”
+</p>
+
+<p>
+“Yes, sir,” replied the dope fiend defiantly.
+</p>
+
+<p>
+“To-day you had to get them elsewhere.”
+</p>
+
+<p>
+No answer.
+</p>
+
+<p>
+“Never mind,” persisted Kennedy, still calm, “I know. Why, Armstrong, you even
+robbed that girl of twenty-five tablets.”
+</p>
+
+<p>
+“I did not,” shot out the answer.
+</p>
+
+<p>
+“There were twenty-five short,” accused Kennedy.
+</p>
+
+<p>
+The two faced each other. Craig repeated his remark.
+</p>
+
+<p>
+“Yes,” replied Armstrong, “I held out the tablets, but it was not for myself, I
+can get all I want. I did it because I didn’t want her to get above
+seventy-five a day. I have tried every way to break her of the habit that has
+got me—and failed. But seventy-five—is the limit!”
+</p>
+
+<p>
+“A pretty story!” exclaimed O’Connor.
+</p>
+
+<p>
+Craig laid his hand on his arm to check him, as he examined a record registered
+on the cylinder of the machine.
+</p>
+
+<p>
+“By the way, Armstrong, I want you to write me out a note that I can use to get
+a hundred heroin tablets. You can write it all but the name of the place where
+I can get them.”
+</p>
+
+<p>
+Armstrong was on the point of demurring, but the last sentence reassured him.
+He would reveal nothing by it—yet.
+</p>
+
+<p>
+Still the man was trembling like a leaf. He wrote:
+</p>
+
+<p>
+“Give Whitecap one hundred shocks—A Victim.”
+</p>
+
+<p>
+For a moment Kennedy studied the note carefully. “Oh—er—I forgot, Armstrong,
+but a few days ago an anonymous letter was sent to Mrs. Sutphen, signed ‘A
+Friend.’ Do you know anything about it?”
+</p>
+
+<p>
+“A note?” the man repeated. “Mrs. Sutphen? I don’t know anything about any
+note, or Mrs. Sutphen either.”
+</p>
+
+<p>
+Kennedy was still studying his record. “This,” he remarked slowly, “is what I
+call my psychophysical test for falsehood. Lying, when it is practiced by an
+expert, is not easily detected by the most careful scrutiny of the liar’s
+appearance and manner.
+</p>
+
+<p>
+“However, successful means have been developed for the detection of falsehood
+by the study of experimental psychology. Walter, I think you will recall the
+test I used once, the psychophysical factor of the character and rapidity of
+the mental process known as the association of ideas?”
+</p>
+
+<p>
+I nodded acquiescence.
+</p>
+
+<p>
+“Well,” he resumed, “in criminal jurisprudence, I find an even more simple and
+more subjective test which has been recently devised. Professor Stoerring of
+Bonn has found out that feelings of pleasure and pain produce well-defined
+changes in respiration. Similar effects are produced by lying, according to the
+famous Professor Benussi of Graz.
+</p>
+
+<p>
+“These effects are unerring, unequivocal. The utterance of a false statement
+increases respiration; of a true statement decreases. The importance and scope
+of these discoveries are obvious.”
+</p>
+
+<p>
+Craig was figuring rapidly on a piece of paper. “This is a certain and
+objective criterion,” he continued as he figured, “between truth and falsehood.
+Even when a clever liar endeavors to escape detection by breathing irregularly,
+it is likely to fail, for Benussi has investigated and found that voluntary
+changes in respiration don’t alter the result. You see, the quotient obtained
+by dividing the time of inspiration by the time of expiration gives me the
+result.”
+</p>
+
+<p>
+He looked up suddenly. “Armstrong, you are telling the truth about some
+things—downright lies about others. You are a drug fiend—but I will be lenient
+with you, for one reason. Contrary to everything that I would have expected,
+you are really trying to save that poor half-witted girl whom you love from the
+terrible habit that has gripped you. That is why you held out the quarter of
+the one hundred tablets. That is why you wrote the note to Mrs. Sutphen, hoping
+that she might be treated in some institution.”
+</p>
+
+<p>
+Kennedy paused as a look of incredulity passed over Armstrong’s face.
+</p>
+
+<p>
+“Another thing you said was true,” added Kennedy. “You can get all the heroin
+you want. Armstrong, you will put the address of that place on the outside of
+the note, or both you and Whitecap go to jail. Snowbird will be left to her own
+devices—she can get all the ‘snow,’ as some of you fiends call it, that she
+wants from those who might exploit her.”
+</p>
+
+<p>
+“Please, Mr. Kennedy,” pleaded Armstrong.
+</p>
+
+<p>
+“No,” interrupted Craig, before the drug fiend could finish. “That is final. I
+must have the name of that place.”
+</p>
+
+<p>
+In a shaky hand Armstrong wrote again. Hastily Craig stuffed the note into his
+pocket, and ten minutes later we were mounting the steps of a big brownstone
+house on a fashionable side street just around the corner from Fifth Avenue.
+</p>
+
+<p>
+As the door was opened by an obsequious colored servant, Craig handed him the
+scrap of paper signed by the password, “A Victim.”
+</p>
+
+<p>
+Imitating the cough of a confirmed dope user, Craig was led into a large
+waiting room.
+</p>
+
+<p>
+“You’re in pretty bad shape, sah,” commented the servant.
+</p>
+
+<p>
+Kennedy nudged me and, taking the cue, I coughed myself red in the face.
+</p>
+
+<p>
+“Yes,” he said. “Hurry—please.”
+</p>
+
+<p>
+The servant knocked at a door, and as it was opened we caught a glimpse of Mrs.
+Garrett in negligee.
+</p>
+
+<p>
+“What is it, Sam?” she asked.
+</p>
+
+<p>
+“Two gentlemen for some heroin tablets, ma’am.”
+</p>
+
+<p>
+“Tell them to go to the chemical works—not to my office, Sam,” growled a man’s
+voice inside.
+</p>
+
+<p>
+With a quick motion, Kennedy had Mrs. Garrett by the wrist.
+</p>
+
+<p>
+“I knew it,” he ground out. “It was all a fake about how you got the habit. You
+wanted to get it, so you could get and hold him. And neither one of you would
+stop at anything, not even the murder of your sister, to prevent the ruin of
+the devilish business you have built up in manufacturing and marketing the
+stuff.”
+</p>
+
+<p>
+He pulled the note from the hand of the surprised negro. “I had the right
+address, the place where you sell hundreds of ounces of the stuff a week—but I
+preferred to come to the doctor’s office where I could find you both.”
+</p>
+
+<p>
+Kennedy had firmly twisted her wrist until, with a little scream of pain, she
+let go the door handle. Then he gently pushed her aside, and the next instant
+Craig had his hand inside the collar of Dr. Coleman, society physician,
+proprietor of the Coleman Chemical Works downtown, the real leader of the drug
+gang that was debauching whole sections of the metropolis.

+THE FAMILY SKELETON</h2>
+
+<p>
+Surprised though we were at the unmasking of Dr. Coleman, there was nothing to
+do but to follow the thing out. In such cases we usually ran into the greatest
+difficulty—organized vice. This was no exception.
+</p>
+
+<p>
+Even when cases involved only a clever individual or a prominent family, it was
+the same. I recall, for example, the case of a well-known family in a New York
+suburb, which was particularly difficult. It began in a rather unusual manner,
+too.
+</p>
+
+<p>
+“Mr. Kennedy—I am ruined—ruined.”
+</p>
+
+<p>
+It was early one morning that the telephone rang and I answered it. A very
+excited German, breathless and incoherent, was evidently at the other end of
+the wire.
+</p>
+
+<p>
+I handed the receiver to Craig and picked up the morning paper lying on the
+table.
+</p>
+
+<p>
+“Minturn—dead?” I heard Craig exclaim. “In the paper this morning? I’ll be down
+to see you directly.”
+</p>
+
+<p>
+Kennedy almost tore the paper from me. In the next to the end column where late
+news usually is dropped was a brief account of the sudden death of Owen
+Minturn, one of the foremost criminal lawyers of the city, in Josephson’s Baths
+downtown.
+</p>
+
+<p>
+It ended: “It is believed by the coroner that Mr. Minturn was shocked to death
+and evidence is being sought to show that two hundred and forty volts of
+electricity had been thrown into the attorney’s body while he was in the
+electric bath. Joseph Josephson, the proprietor of the bath, who operated the
+switchboard, is being held, pending the completion of the inquiry.”
+</p>
+
+<p>
+As Kennedy hastily ran his eye over the paragraphs, he became more and more
+excited himself.
+</p>
+
+<p>
+“Walter,” he cried, as he finished, “I don’t believe that that was an accident
+at all.”
+</p>
+
+<p>
+“Why?” I asked.
+</p>
+
+<p>
+He already had his hat on, and I knew he was going to Josephson’s
+breakfastless. I followed reluctantly.
+</p>
+
+<p>
+“Because,” he answered, as we hustled along in the early morning crowd, “it was
+only yesterday afternoon that I saw Minturn at his office and he made an
+appointment with me for this very morning. He was a very secretive man, but he
+did tell me this much, that he feared his life was in danger and that it was in
+some way connected with that Pearcy case up in Stratfield, Connecticut, where
+he has an estate. You have read of the case?”
+</p>
+
+<p>
+Indeed I had. It had seemed to me to be a particularly inexplicable affair.
+Apparently a whole family had been poisoned and a few days before old Mr.
+Randall Pearcy, a retired manufacturer, had died after a brief but mysterious
+illness.
+</p>
+
+<p>
+Pearcy had been married a year or so ago to Annette Oakleigh, a Broadway comic
+opera singer, who was his second wife. By his first marriage he had had two
+children, a son, Warner, and a daughter, Isabel.
+</p>
+
+<p>
+Warner Pearcy, I had heard, had blazed a vermilion trail along the Great White
+Way, but his sister was of the opposite temperament, interested in social work,
+and had attracted much attention by organizing a settlement in the slums of
+Stratfield for the uplift of the workers in the Pearcy and other mills.
+</p>
+
+<p>
+Broadway, as well as Stratfield, had already woven a fantastic background, for
+the mystery and hints had been broadly made that Annette Oakleigh had been
+indiscreetly intimate with a young physician in the town, a Dr. Gunther, a
+friend, by the way, of Minturn. “There has been no trial yet,” went on Kennedy,
+“but Minturn seems to have appeared before the coroner’s jury at Stratfield and
+to have asserted the innocence of Mrs. Pearcy and that of Dr. Gunther so well
+that, although the jury brought in a verdict of murder by poison by some one
+unknown, there has been no mention of the name of anyone else. The coroner
+simply adjourned the inquest so that a more careful analysis might be made of
+the vital organs. And now comes this second tragedy in New York.”
+</p>
+
+<p>
+“What was the poison?” I asked. “Have they found out yet?”
+</p>
+
+<p>
+“They are pretty sure, so Minturn told me, that it was lead poisoning. The fact
+not generally known is,” he added in a lower tone, “that the cases were not
+confined to the Pearcy house. They had even extended to Minturn’s too, although
+about that he said little yesterday. The estates up there adjoin, you know.”
+</p>
+
+<p>
+Owen Minturn, I recalled, had gained a formidable reputation by his successful
+handling of cases from the lowest strata of society to the highest. Indeed it
+was a byword that his appearance in court indicated two things—the guilt of the
+accused and a verdict of acquittal.
+</p>
+
+<p>
+“Of course,” Craig pursued as we were jolted from station to station downtown,
+“you know they say that Minturn never kept a record of a case. But written
+records were as nothing compared to what that man must have carried only in his
+head.”
+</p>
+
+<p>
+It was a common saying that, if Minturn should tell all he knew, he might hang
+half a dozen prominent men in society. That was not strictly true, perhaps, but
+it was certain that a revelation of the things confided to him by clients which
+were never put down on paper would have caused a series of explosions that
+would have wrecked at least some portions of the social and financial world. He
+had heard much and told little, for he had been a sort of “father confessor.”
+</p>
+
+<p>
+Had Minturn, I wondered, known the name of the real criminal?
+</p>
+
+<p>
+Josephson’s was a popular bath on Forty-second Street, where many of the
+“sun-dodgers” were accustomed to recuperate during the day from their arduous
+pursuit of pleasure at night and prepare for the resumption of their toil
+during the coming night. It was more than that, however, for it had a
+reputation for being conducted really on a high plane.
+</p>
+
+<p>
+We met Josephson downstairs. He had been released under bail, though the place
+was temporarily closed and watched over by the agents of the coroner and the
+police. Josephson appeared to be a man of some education and quite different
+from what I had imagined from hearing him over the telephone.
+</p>
+
+<p>
+“Oh, Mr. Kennedy,” he exclaimed, “who now will come to my baths? Last night
+they were crowded, but to-day—”
+</p>
+
+<p>
+He ended with an expressive gesture of his hands.
+</p>
+
+<p>
+“One customer I have surely lost, young Mr. Pearcy,” he went on.
+</p>
+
+<p>
+“Warner Pearcy?” asked Craig. “Was he here last night?”
+</p>
+
+<p>
+“Nearly every night,” replied Josephson, now glib enough as his first
+excitement subsided and his command of English returned. “He was a neighbor of
+Mr. Minturn’s, I hear. Oh, what luck!” growled Josephson as the name recalled
+him to his present troubles.
+</p>
+
+<p>
+“Well,” remarked Kennedy with an attempt at reassurance as if to gain the
+masseur’s confidence, “I know as well as you that it is often amazing what a
+tremendous shock a man may receive and yet not be killed, and no less amazing
+how small a shock may kill. It all depends on circumstances.”
+</p>
+
+<p>
+Josephson shot a covert look at Kennedy. “Yes,” he reiterated, “but I cannot
+see how it <i>could</i> be. If the lights had become short-circuited with the
+bath, that might have thrown a current into the bath. But they were not. I know
+it.”
+</p>
+
+<p>
+“Still,” pursued Kennedy, watching him keenly, “it is not all a question of
+current. To kill, the shock must pass through a vital organ—the brain, the
+heart, the upper spinal cord. So, a small shock may kill and a large one may
+not. If it passes in one foot and out by the other, the current isn’t likely to
+be as dangerous as if it passes in by a hand or foot and then out by a foot or
+hand. In one case it passes through no vital organ; in the other it is very
+likely to do so. You see, the current can flow through the body only when it
+has a place of entrance and a place of exit. In all cases of accident from
+electric light wires, the victim is touching some conductor—damp earth, salty
+earth, water, something that gives the current an outlet and—”
+</p>
+
+<p>
+“But even if the lights had been short-circuited,” interrupted Josephson, “Mr.
+Minturn would have escaped injury unless he had touched the taps of the bath.
+Oh, no, sir, accidents in the medical use of electricity are rare. They don’t
+happen here in my establishment,” he maintained stoutly. “The trouble was that
+the coroner, without any knowledge of the physiological effects of electricity
+on the body, simply jumped at once to the conclusion that it was the electric
+bath that did it.”
+</p>
+
+<p>
+“Then it was for medical treatment that Mr. Minturn was taking the bath?” asked
+Kennedy, quickly taking up the point.
+</p>
+
+<p>
+“Yes, of course,” answered the masseur, eager to explain. “You are acquainted
+with the latest treatment for lead poisoning by means of the electric bath?”
+</p>
+
+<p>
+Kennedy nodded. “I know that Sir Thomas Oliver, the English authority who has
+written much on dangerous trades, has tried it with marked success.”
+</p>
+
+<p>
+“Well, sir, that was why Mr. Minturn was here. He came here introduced by a Dr.
+Gunther of Stratfield.”
+</p>
+
+<p>
+“Indeed?” remarked Kennedy colorlessly, though I could see that it interested
+him, for evidently Minturn had said nothing of being himself a sufferer from
+the poison. “May I see the bath?”
+</p>
+
+<p>
+“Surely,” said Josephson, leading the way upstairs.
+</p>
+
+<p>
+It was an oaken tub with metal rods on the two long sides, from which depended
+prismatic carbon rods. Kennedy examined it closely.
+</p>
+
+<p>
+“This is what we call a hydro-electric bath,” Josephson explained. “Those rods
+on the sides are the electrodes. You see there are no metal parts in the tub
+itself. The rods are attached by wiring to a wall switch out here.”
+</p>
+
+<p>
+He pointed to the next room. Kennedy examined the switch with care.
+</p>
+
+<p>
+“From it,” went on Josephson, “wires lead to an accumulator battery of perhaps
+thirty volts. It uses very little current. Dr. Gunther tested it and found it
+all right.”
+</p>
+
+<p>
+Craig leaned over the bath, and from the carbon electrodes scraped off a white
+powder in minute crystals.
+</p>
+
+<p>
+“Ordinarily,” Josephson pursued, “lead is eliminated by the skin and kidneys.
+But now, as you know, it is being helped along by electrolysis. I talked to Dr.
+Gunther about it. It is his opinion that it is probably eliminated as a
+chloride from the tissues of the body to the electrodes in the bath in which
+the patient is wholly or partly immersed. On the positive electrodes we get the
+peroxide. On the negative there is a spongy metallic form of lead. But it is
+only a small amount.”
+</p>
+
+<p>
+“The body has been removed?” asked Craig.
+</p>
+
+<p>
+“Not yet,” the masseur replied. “The coroner has ordered it kept here under
+guard until he makes up his mind what disposition to have made of it.”
+</p>
+
+<p>
+We were next ushered into a little room on the same floor, at the door of which
+was posted an official from the coroner.
+</p>
+
+<p>
+“First of all,” remarked Craig, as he drew back the sheet and began, a minute
+examination of the earthly remains of the great lawyer, “there are to be
+considered the safeguards of the human body against the passage through it of a
+fatal electric current—the high electric resistance of the body itself. It is
+particularly high when the current must pass through joints such as wrists,
+knees, elbows, and quite high when the bones of the head are concerned. Still,
+there might have been an incautious application of the current to the head,
+especially when the subject is a person of advanced age or latent cerebral
+disease, though I don’t know that that fits Mr. Minturn. That’s strange,” he
+muttered, looking up, puzzled. “I can find no mark of a burn on the
+body—absolutely no mark of anything.”
+</p>
+
+<p>
+“That’s what I say,” put in Josephson, much pleased by what Kennedy said, for
+he had been waiting anxiously to see what Craig discovered on his own
+examination. “It’s impossible.”
+</p>
+
+<p>
+“It’s all the more remarkable,” went on Craig, half to himself and ignoring
+Josephson, “because burns due to electric currents are totally unlike those
+produced in other ways. They occur at the point of contact, usually about the
+arms and hands, or the head. Electricity is much to be feared when it involves
+the cranial cavity.” He completed his examination of the head which once had
+carried secrets which themselves must have been incandescent.
+</p>
+
+<p>
+“Then, too, such burns are most often something more than superficial, for
+considerable heat is developed which leads to massive destruction and
+carbonization of the tissues to a considerable depth. I have seen actual losses
+of substance—a lump of killed flesh surrounded by healthy tissues. Besides,
+such burns show an unexpected indolence when compared to the violent pains of
+ordinary burns. Perhaps that is due to the destruction of the nerve endings.
+How did Minturn die? Was he alone? Was he dead when he was discovered?”
+</p>
+
+<p>
+“He was alone,” replied Josephson, slowly endeavoring to tell it exactly as he
+had seen it, “but that’s the strange part of it. He seemed to be suffering from
+a convulsion. I think he complained at first of a feeling of tightness of his
+throat and a twitching of the muscles of his hands and feet. Anyhow, he called
+for help. I was up here and we rushed in. Dr. Gunther had just brought him and
+then had gone away, after introducing him, and showing him the bath.”
+</p>
+
+<p>
+Josephson proceeded slowly, evidently having been warned that anything he said
+might be used against him. “We carried him, when he was this way, into this
+very room. But it was only for a short time. Then came a violent convulsion. It
+seemed to extend rapidly all over his body. His legs were rigid, his feet bent,
+his head back. Why, he was resting only on his heels and the back of his head.
+You see, Mr. Kennedy, that simply could not be the electric shock.”
+</p>
+
+<p>
+“Hardly,” commented Kennedy, looking again at the body. “It looks more like a
+tetanus convulsion. Yet there does not seem to be any trace of a recent wound
+that might have caused lockjaw. How did he look?”
+</p>
+
+<p>
+“Oh, his face finally became livid,” replied Josephson. “He had a ghastly,
+grinning expression, his eyes were wide, there was foam on his mouth, and his
+breathing was difficult.”
+</p>
+
+<p>
+“Not like tetanus, either,” revised Craig. “There the convulsion usually begins
+with the face and progresses to the other muscles. Here it seems to have gone
+the other way.”
+</p>
+
+<p>
+“That lasted a minute or so,” resumed the masseur. “Then he sank back—perfectly
+limp. I thought he was dead. But he was not. A cold sweat broke out all over
+him and he was as if in a deep sleep.”
+</p>
+
+<p>
+“What did you do?” prompted Kennedy.
+</p>
+
+<p>
+“I didn’t know what to do. I called an ambulance. But the moment the door
+opened, his body seemed to stiffen again. He had one other convulsion—and when
+he grew limp he was dead.”

+<h2><a name="chap29"></a>CHAPTER XXIX<br/>
+THE LEAD POISONER</h2>
+
+<p>
+It was a gruesome recital and I was glad to leave the baths finally with
+Kennedy. Josephson was quite evidently relieved at the attitude Craig had taken
+toward the coroner’s conclusion that Minturn had been shocked to death. As far
+as I could see, however, it added to rather than cleared up the mystery.
+</p>
+
+<p>
+Craig went directly uptown to his laboratory, in contrast with our journey
+down, in abstracted silence, which was his manner when he was trying to reason
+out some particularly knotty problem.
+</p>
+
+<p>
+As Kennedy placed the white crystals which he had scraped off the electrodes of
+the tub on a piece of dark paper in the laboratory, he wet the tip of his
+finger and touched just the minutest grain to his tongue.
+</p>
+
+<p>
+The look on his face told me that something unexpected had happened. He held a
+similar minute speck of the powder out to me.
+</p>
+
+<p>
+It was an intensely bitter taste and very persistent, for even after we had
+rinsed out our mouths it seemed to remain, clinging persistently to the tongue.
+</p>
+
+<p>
+He placed some of the grains in some pure water. They dissolved only slightly,
+if at all. But in a tube in which he mixed a little ether and chloroform they
+dissolved fairly readily.
+</p>
+
+<p>
+Next, without a word, he poured just a drop of strong sulphuric acid on the
+crystals. There was not a change in them.
+</p>
+
+<p>
+Quickly he reached up into the rack and took down a bottle labeled “Potassium
+Bichromate.”
+</p>
+
+<p>
+“Let us see what an oxidizing agent will do,” he remarked.
+</p>
+
+<p>
+As he gently added the bichromate, there came a most marvelous, kaleidoscopic
+change. From being almost colorless, the crystals turned instantly to a deep
+blue, then rapidly to purple, lilac, red, and then the red slowly faded away
+and they became colorless again.
+</p>
+
+<p>
+“What is it?” I asked, fascinated. “Lead?”
+</p>
+
+<p>
+“N-no,” he replied, the lines of his forehead deepening. “No. This is sulphate
+of strychnine.”
+</p>
+
+<p>
+“Sulphate of strychnine?” I repeated in astonishment.
+</p>
+
+<p>
+“Yes,” he reiterated slowly. “I might have suspected that from the convulsions,
+particularly when Josephson said that the noise and excitement of the arrival
+of the ambulance brought on the fatal paroxysm. That is symptomatic. But I
+didn’t fully realize it until I got up here and tasted the stuff. Then I
+suspected, for that taste is characteristic. Even one part diluted seventy
+thousand times gives that decided bitter taste.”
+</p>
+
+<p>
+“That’s all very well,” I remarked, recalling the intense bitterness yet on my
+tongue. “But how do you suppose it was possible for anyone to administer it? It
+seems to me that he would have said something, if he had swallowed even the
+minutest part of it. He must have known it. Yet apparently he didn’t. At least
+he said nothing about it—or else Josephson is concealing something.”
+</p>
+
+<p>
+“Did he swallow it—necessarily?” queried Kennedy, in a tone calculated to show
+me that the chemical world, at least, was full of a number of things, and there
+was much to learn.
+</p>
+
+<p>
+“Well, I suppose if it had been given hypodermically, it would have a more
+violent effect,” I persisted, trying to figure out a way that the poison might
+have been given.
+</p>
+
+<p>
+“Even more unlikely,” objected Craig, with a delight at discovering a new
+mystery that to me seemed almost fiendish. “No, he would certainly have felt a
+needle, have cried out and said something about it, if anyone had tried that.
+This poisoned needle business isn’t as easy as some people seem to think
+nowadays.”
+</p>
+
+<p>
+“Then he might have absorbed it from the water,” I insisted, recalling a recent
+case of Kennedy’s and adding, “by osmosis.”
+</p>
+
+<p>
+“You saw how difficult it was to dissolve in water,” Craig rejected quietly.
+</p>
+
+<p>
+“Well, then,” I concluded in desperation. “How could it have been introduced?”
+</p>
+
+<p>
+“I have a theory,” was all he would say, reaching for the railway guide, “but
+it will take me up to Stratfield to prove it.”
+</p>
+
+<p>
+His plan gave us a little respite and we paused long enough to lunch, for which
+breathing space I was duly thankful. The forenoon saw us on the train, Kennedy
+carrying a large and cumbersome package which he brought down with him from the
+laboratory and which we took turns in carrying, though he gave no hint of its
+contents.
+</p>
+
+<p>
+We arrived in Stratfield, a very pretty little mill town, in the middle of the
+afternoon, and with very little trouble were directed to the Pearcy house,
+after Kennedy had checked the parcel with the station agent.
+</p>
+
+<p>
+Mrs. Pearcy, to whom we introduced ourselves as reporters of the <i>Star</i>,
+was a tall blonde. I could not help thinking that she made a particularly
+dashing widow. With her at the time was Isabel Pearcy, a slender girl whose
+sensitive lips and large, earnest eyes indicated a fine, high-strung nature.
+</p>
+
+<p>
+Even before we had introduced ourselves, I could not help thinking that there
+was a sort of hostility between the women. Certainly it was evident that there
+was as much difference in temperament as between the butterfly and the bee.
+</p>
+
+<p>
+“No,” replied the elder woman quickly to a request from Kennedy for an
+interview, “there is nothing that I care to say to the newspapers. They have
+said too much already about this—unfortunate affair.”
+</p>
+
+<p>
+Whether it was imagination or not, I fancied that there was an air of reserve
+about both women. It struck me as a most peculiar household. What was it? Was
+each suspicious of the other? Was each concealing something?
+</p>
+
+<p>
+I managed to steal a glance at Kennedy’s face to see whether there was anything
+to confirm my own impression. He was watching Mrs. Pearcy closely as she spoke.
+In fact his next few questions, inconsequential as they were, seemed addressed
+to her solely for the purpose of getting her to speak.
+</p>
+
+<p>
+I followed his eyes and found that he was watching her mouth, in reality. As
+she answered I noted her beautiful white teeth. Kennedy himself had trained me
+to notice small things, and at the time, though I thought it was trivial, I
+recall noticing on her gums, where they joined the teeth, a peculiar
+bluish-black line.
+</p>
+
+<p>
+Kennedy had been careful to address only Mrs. Pearcy at first, and as he
+continued questioning her, she seemed to realize that he was trying to lead her
+along.
+</p>
+
+<p>
+“I must positively refuse to talk any more,” she repeated finally, rising. “I
+am not to be tricked into saying anything.”
+</p>
+
+<p>
+She had left the room, evidently expecting that Isabel would follow. She did
+not. In fact I felt that Miss Pearcy was visibly relieved by the departure of
+her stepmother. She seemed anxious to ask us something and now took the first
+opportunity.
+</p>
+
+<p>
+“Tell me,” she said eagerly, “how did Mr. Minturn die? What do they really
+think of it in New York?”
+</p>
+
+<p>
+“They think it is poisoning,” replied Craig, noting the look on her face.
+</p>
+
+<p>
+She betrayed nothing, as far as I could see, except a natural neighborly
+interest. “Poisoning?” she repeated. “By what?”
+</p>
+
+<p>
+“Lead poisoning,” he replied evasively.
+</p>
+
+<p>
+She said nothing. It was evident that, slip of a girl though she was, she was
+quite the match of anyone who attempted leading questions. Kennedy changed his
+method.
+</p>
+
+<p>
+“You will pardon me,” he said apologetically, “for recalling what must be
+distressing. But we newspapermen often have to do things and ask questions that
+are distasteful. I believe it is rumored that your father suffered from lead
+poisoning?”
+</p>
+
+<p>
+“Oh, I don’t know what it was—none of us do,” she cried, almost pathetically.
+“I had been living at the settlement until lately. When father grew worse, I
+came home. He had such strange visions—hallucinations, I suppose you would call
+them. In the daytime he would be so very morose and melancholy. Then, too,
+there were terrible pains in his stomach, and his eyesight began to fail. Yes,
+I believe that Dr. Gunther did say it was lead poisoning. But—they have said so
+many things—so many things,” she repeated, plainly distressed at the subject of
+her recent bereavement.
+</p>
+
+<p>
+“Your brother is not at home?” asked Kennedy, quickly changing the subject.
+</p>
+
+<p>
+“No,” she answered, then with a flash as though lifting the veil of a
+confidence, added: “You know, neither Warner nor I have lived here much this
+year. He has been in New York most of the time and I have been at the
+settlement, as I already told you.”
+</p>
+
+<p>
+She hesitated, as if wondering whether she should say more, then added quickly:
+“It has been repeated often enough; there is no reason why I shouldn’t say it
+to you. Neither of us exactly approved of father’s marriage.”
+</p>
+
+<p>
+She checked herself and glanced about, somewhat with the air of one who has
+suddenly considered the possibility of being overheard.
+</p>
+
+<p>
+“May I have a glass of water?” asked Kennedy suddenly.
+</p>
+
+<p>
+“Why, certainly,” she answered, going to the door, apparently eager for an
+excuse to find out whether there was some one on the other side of it.
+</p>
+
+<p>
+There was not, nor any indication that there had been.
+</p>
+
+<p>
+“Evidently she does not have any suspicions of <i>that</i>,” remarked Kennedy
+in an undertone, half to himself.
+</p>
+
+<p>
+I had no chance to question him, for she returned almost immediately. Instead
+of drinking the water, however, he held it carefully up to the light. It was
+slightly turbid.
+</p>
+
+<p>
+“You drink the water from the tap?” he asked, as he poured some of it into a
+sterilized vial which he drew quickly from his vest pocket.
+</p>
+
+<p>
+“Certainly,” she replied, for the moment nonplussed at his strange actions.
+“Everybody drinks the town water in Stratfield.”
+</p>
+
+<p>
+A few more questions, none of which were of importance, and Kennedy and I
+excused ourselves.
+</p>
+
+<p>
+At the gate, instead of turning toward the town, however, Kennedy went on and
+entered the grounds of the Minturn house next door. The lawyer, I had
+understood, was a widower and, though he lived in Stratfield only part of the
+time, still maintained his house there.
+</p>
+
+<p>
+We rang the bell and a middle-aged housekeeper answered.
+</p>
+
+<p>
+“I am from the water company,” he began politely. “We are testing the water,
+perhaps will supply consumers with filters. Can you let me have a sample?”
+</p>
+
+<p>
+She did not demur, but invited us in. As she drew the water, Craig watched her
+hands closely. She seemed to have difficulty in holding the glass, and as she
+handed it to him, I noticed a peculiar hanging down of the wrist. Kennedy
+poured the sample into a second vial, and I noticed that it was turbid, too.
+With no mention of the tragedy to her employer, he excused himself, and we
+walked slowly back to the road.
+</p>
+
+<p>
+Between the two houses Kennedy paused, and for several moments appeared to be
+studying them.
+</p>
+
+<p>
+We walked slowly back along the road to the town. As we passed the local drug
+store, Kennedy turned and sauntered in.
+</p>
+
+<p>
+He found it easy enough to get into conversation with the druggist, after
+making a small purchase, and in the course of a few minutes we found ourselves
+gossiping behind the partition that shut off the arcana of the prescription
+counter from the rest of the store.
+</p>
+
+<p>
+Gradually Kennedy led the conversation around to the point which he wanted, and
+asked, “I wish you’d let me fix up a little sulphureted hydrogen.”
+</p>
+
+<p>
+“Go ahead,” granted the druggist good-naturedly. “I guess you can do it. You
+know as much about drugs as I do. I can stand the smell, if you can.”
+</p>
+
+<p>
+Kennedy smiled and set to work.
+</p>
+
+<p>
+Slowly he passed the gas through the samples of water he had taken from the two
+houses. As he did so the gas, bubbling through, made a blackish precipitate.
+</p>
+
+<p>
+“What is it?” asked the druggist curiously.
+</p>
+
+<p>
+“Lead sulphide,” replied Kennedy, stroking his chin. “This is an extremely
+delicate test. Why, one can get a distinct brownish tinge if lead is present in
+even incredibly minute quantities.”
+</p>
+
+<p>
+He continued to work over the vials ranged on the table before him.
+</p>
+
+<p>
+“The water contains, I should say, from ten to fifteen hundredths of a grain of
+lead to the gallon,” he remarked finally.
+</p>
+
+<p>
+“Where did it come from?” asked the druggist, unable longer to restrain his
+curiosity.
+</p>
+
+<p>
+“I got it up at Pearcy’s,” Kennedy replied frankly, turning to observe whether
+the druggist might betray any knowledge of it.
+</p>
+
+<p>
+“That’s strange,” he replied in genuine surprise. “Our water in Stratfield is
+supplied by a company to a large area, and it has always seemed to me to be of
+great organic purity.”
+</p>
+
+<p>
+“But the pipes are of lead, are they not?” asked Kennedy.
+</p>
+
+<p>
+“Y-yes,” answered the druggist, “I think in most places the service pipes are
+of lead. But,” he added earnestly as he saw the implication of his admission,
+“water has never to my knowledge been found to attack the pipes so as to affect
+its quality injuriously.”
+</p>
+
+<p>
+He turned his own faucet and drew a glassful. “It is normally quite clear,” he
+added, holding the glass up.
+</p>
+
+<p>
+It was in fact perfectly clear, and when he passed some of the gas through it
+nothing happened at all.
+</p>
+
+<p>
+Just then a man lounged into the store.
+</p>
+
+<p>
+“Hello, Doctor,” greeted the druggist. “Here are a couple of fellows that have
+been investigating the water up at Pearcy’s. They’ve found lead in it. That
+ought to interest you. This is Dr. Gunther,” he introduced, turning to us.
+</p>
+
+<p>
+It was an unexpected encounter, one I imagine that Kennedy might have preferred
+to take place under other circumstances. But he was equal to the occasion.
+</p>
+
+<p>
+“We’ve been sent up here to look into the case for the New York <i>Star</i>,”
+Kennedy said quickly. “I intended to come around to see you, but you have saved
+me the trouble.”
+</p>
+
+<p>
+Dr. Gunther looked from one of us to the other. “Seems to me the New York
+papers ought to have enough to do without sending men all over the country
+making news,” he grunted.
+</p>
+
+<p>
+“Well,” drawled Kennedy quietly, “there seems to be a most remarkable situation
+up there at Pearcy’s and Minturn’s, too. As nearly as I can make out several
+people there are suffering from unmistakable signs of lead poisoning. There are
+the pains in the stomach, the colic, and then on the gums is that
+characteristic line of plumbic sulphide, the distinctive mark produced by lead.
+There is the wrist-drop, the eyesight affected, the partial paralysis, the
+hallucinations and a condition in old Pearcy’s case almost bordering on
+insanity—to enumerate the symptoms that seem to be present in varying degrees
+in various persons in the two houses.”
+</p>
+
+<p>
+Gunther looked at Kennedy, as if in doubt just how to take him.
+</p>
+
+<p>
+“That’s what the coroner says, too—lead poisoning,” put in the druggist,
+himself as keen as anyone else for a piece of local news, and evidently not
+averse to stimulating talk from Dr. Gunther, who had been Pearcy’s physician.
+</p>
+
+<p>
+“That all seems to be true enough,” replied Gunther at length guardedly. “I
+recognized that some time ago.”
+</p>
+
+<p>
+“Why do you think it affects each so differently?” asked the druggist.
+</p>
+
+<p>
+Dr. Gunther settled himself easily back in a chair to speak as one having
+authority. “Well,” he began slowly, “Miss Pearcy, of course, hasn’t been living
+there much until lately. As for the others, perhaps this gentleman here from
+the <i>Star</i> knows that lead, once absorbed, may remain latent in the system
+and then make itself felt. It is like arsenic, an accumulative poison, slowly
+collecting in the body until the limit is reached, or until the body, becoming
+weakened from some other cause, gives way to it.”
+</p>
+
+<p>
+He shifted his position slowly, and went on, as if defending the course of
+action he had taken in the case.
+</p>
+
+<p>
+“Then, too, you know, there is an individual as well as family and sex
+susceptibility to lead. Women are especially liable to lead poisoning, but then
+perhaps in this case Mrs. Pearcy comes of a family that is very resistant.
+There are many factors. Personally, I don’t think Pearcy himself was resistant.
+Perhaps Minturn was not, either. At any rate, after Pearcy’s death, it was I
+who advised Minturn to take the electrolysis cure in New York. I took him down
+there,” added Gunther. “Confound it, I wish I had stayed with him. But I always
+found Josephson perfectly reliable in hydrotherapy with other patients I sent
+to him, and I understood that he had been very successful with cases sent to
+him by many physicians in the city.” He paused and I waited anxiously to see
+whether Kennedy would make some reference to the discovery of the strychnine
+salts.
+</p>
+
+<p>
+“Have you any idea how the lead poisoning could have been caused?” asked
+Kennedy instead.
+</p>
+
+<p>
+Dr. Gunther shook his head. “It is a puzzle to me,” he answered. “I am sure of
+only one thing. It could not be from working in lead, for it is needless to say
+that none of them worked.”
+</p>
+
+<p>
+“Food?” Craig suggested.
+</p>
+
+<p>
+The doctor considered. “I had thought of that. I know that many cases of lead
+poisoning have been traced to the presence of the stuff in ordinary foods,
+drugs and drinks. I have examined the foods, especially the bread. They don’t
+use canned goods. I even went so far as to examine the kitchen ware to see if
+there could be anything wrong with the glazing. They don’t drink wines and
+beers, into which now and then the stuff seems to get.”
+</p>
+
+<p>
+“You seem to have a good grasp of the subject,” flattered Kennedy, as we rose
+to go. “I can hardly blame you for neglecting the water, since everyone here
+seems to be so sure of the purity of the supply.”
+</p>
+
+<p>
+Gunther said nothing. I was not surprised, for, at the very least, no one likes
+to have an outsider come in and put his finger directly on the raw spot. What
+more there might be to it, I could only conjecture.
+</p>
+
+<p>
+We left the druggist’s and Kennedy, glancing at his watch, remarked: “If you
+will go down to the station, Walter, and get that package we left there, I
+shall be much obliged to you. I want to make just one more stop, at the office
+of the water company, and I think I shall just about have time for it. There’s
+a pretty good restaurant across the street. Meet me there, and by that time I
+shall know whether to carry out a little plan I have outlined or not.”

+<h2><a name="chap30"></a>CHAPTER XXX<br/>
+THE ELECTROLYTIC MURDER</h2>
+
+<p>
+We dined leisurely, which seemed strange to me, for it was not Kennedy’s custom
+to let moments fly uselessly when he was on a case. However, I soon found out
+why it was. He was waiting for darkness.
+</p>
+
+<p>
+As soon as the lights began to glow in the little stores on the main street, we
+sallied forth, taking the direction of the Pearcy and Minturn houses.
+</p>
+
+<p>
+On the way he dropped into the hardware store and purchased a light spade and
+one of the small pocket electric flashlights, about which he wrapped a piece of
+cardboard in such a way as to make a most effective dark lantern.
+</p>
+
+<p>
+We trudged along in silence, occasionally changing from carrying the heavy
+package to the light spade.
+</p>
+
+<p>
+Both the Pearcy and Minturn houses were in nearly total darkness when we
+arrived. They set well back from the road and were plentifully shielded by
+shrubbery. Then, too, at night it was not a much frequented neighborhood. We
+could easily hear the footsteps of anyone approaching on the walk, and an
+occasional automobile gliding past did not worry us in the least.
+</p>
+
+<p>
+“I have calculated carefully from an examination of the water company’s map,”
+said Craig, “just where the water pipe of the two houses branches off from the
+main in the road.”
+</p>
+
+<p>
+After a measurement or two from some landmark, we set to work a few feet
+inside, under cover of the bushes and the shadows, like two grave diggers.
+</p>
+
+<p>
+Kennedy had been wielding the spade vigorously for a few minutes when it
+touched something metallic. There, just beneath the frost line, we came upon
+the service pipe.
+</p>
+
+<p>
+He widened the hole, and carefully scraped off the damp earth that adhered to
+the pipe. Next he found a valve where he shut off the water and cut out a small
+piece of the pipe.
+</p>
+
+<p>
+“I hope they don’t suspect anything like this in the houses with their water
+cut off,” he remarked as he carefully split the piece open lengthwise and
+examined it under the light.
+</p>
+
+<p>
+On the interior of the pipe could be seen patchy lumps of white which projected
+about an eighth of an inch above the internal surface. As the pipe dried in the
+warm night air, they could easily be brushed off as a white powder.
+</p>
+
+<p>
+“What is it—strychnine?” I asked.
+</p>
+
+<p>
+“No,” he replied, regarding it thoughtfully with some satisfaction. “That is
+lead carbonate. There can be no doubt that the turbidity of the water was due
+to this powder in suspension. A little dissolves in the water, while the scales
+and incrustations in fine particles are carried along in the current. As a
+matter of fact the amount necessary to make the water poisonous need not be
+large.”
+</p>
+
+<p>
+He applied a little instrument to the cut ends of the pipe. As I bent over, I
+could see the needle on its dial deflected just a bit.
+</p>
+
+<p>
+“My voltmeter,” he said, reading it, “shows that there is a current of about
+1.8 volts passing through this pipe all the time.”
+</p>
+
+<p>
+“Electrolysis of water pipes!” I exclaimed, thinking of statements I had heard
+by engineers. “That’s what they mean by stray or vagabond currents, isn’t it?”
+</p>
+
+<p>
+He had seized the lantern and was eagerly following up and down the line of the
+water pipe. At last he stopped, with a low exclamation, at a point where an
+electric light wire supplying the Minturn cottage crossed overhead. Fastened
+inconspicuously to the trunk of a tree which served as a support for the wire
+was another wire which led down from it and was buried in the ground.
+</p>
+
+<p>
+Craig turned up the soft earth as fast as he could, until he reached the pipe
+at this point. There was the buried wire wound several times around it.
+</p>
+
+<p>
+As quickly and as neatly as he could he inserted a connection between the
+severed ends of the pipe to restore the flow of water to the houses, turned on
+the water and covered up the holes he had dug. Then he unwrapped the package
+which we had tugged about all day, and in a narrow path between the bushes
+which led to the point where the wire had tapped the electric light feed he
+placed in a shallow hole in the ground a peculiar apparatus.
+</p>
+
+<p>
+As nearly as I could make it out, it consisted of two flat platforms between
+which, covered over and projected, was a slip of paper which moved forward,
+actuated by clockwork, and pressed on by a sort of stylus. Then he covered it
+over lightly with dirt so that, unless anyone had been looking for it, it would
+never be noticed.
+</p>
+
+<p>
+It was late when we reached the city again, but Kennedy had one more piece of
+work and that devolved on me. All the way down on the train he had been writing
+and rewriting something.
+</p>
+
+<p>
+“Walter,” he said, as the train pulled into the station, “I want that published
+in to-morrow’s papers.”
+</p>
+
+<p>
+I looked over what he had written. It was one of the most sensational stories I
+have ever fathered, beginning, “Latest of the victims of the unknown poisoner
+of whole families in Stratfield, Connecticut, is Miss Isabel Pearcy, whose
+father, Randall Pearcy, died last week.”
+</p>
+
+<p>
+I knew that it was a “plant” of some kind, for so far he had discovered no
+evidence that Miss Pearcy had been affected. What his purpose was, I could not
+guess, but I got the story printed.
+</p>
+
+<p>
+The next morning early Kennedy was quietly at work in the laboratory.
+</p>
+
+<p>
+“What is this treatment of lead poisoning by electrolysis?” I asked, now that
+there had come a lull when I might get an intelligible answer. “How does it
+work?”
+</p>
+
+<p>
+“Brand new, Walter,” replied Kennedy. “It has been discovered that ions will
+flow directly through the membranes.”
+</p>
+
+<p>
+“Ions?” I repeated. “What are ions?”
+</p>
+
+<p>
+“Travelers,” he answered, smiling, “so named by Faraday from the Greek verb,
+<i>io</i>, to go. They are little positive and negative charges of electricity
+of which molecules are composed. You know some believe now that matter is
+really composed of electrical energy. I think I can explain it best by a simile
+I use with my classes. It is as though you had a ballroom in which the dancers
+in couples represent the neutral molecules. There are a certain number of
+isolated ladies and gentlemen—dissociated ions—” “Who don’t know these new
+dances?” I interrupted.
+</p>
+
+<p>
+“They all know this dance,” he laughed. “But, to be serious in the simile,
+suppose at one end of the room there is a large mirror and at the other a
+buffet with cigars and champagne. What happens to the dissociated ions?”
+</p>
+
+<p>
+“Well, I suppose you want me to say that the ladies gather about the mirror and
+the men about the buffet.”
+</p>
+
+<p>
+“Exactly. And some of the dancing partners separate and follow the crowd. Well,
+that room presents a picture of what happens in an electrolytic solution at the
+moment when the electric current is passing through it.”
+</p>
+
+<p>
+“Thanks,” I laughed. “That was quite adequate to my immature understanding.”
+</p>
+
+<p>
+Kennedy continued at work, checking up and arranging his data until the middle
+of the afternoon, when he went up to Stratfield.
+</p>
+
+<p>
+Having nothing better to do, I wandered out about town in the hope of running
+across some one with whom to while away the hours until Kennedy returned. I
+found out that, since yesterday, Broadway had woven an entirely new background
+for the mystery. Now it was rumored that the lawyer Minturn himself had been on
+very intimate terms with Mrs. Pearcy. I did not pay much attention to the
+rumor, for I knew that Broadway is constitutionally unable to believe that
+anybody is straight.
+</p>
+
+<p>
+Kennedy had commissioned me to keep in touch with Josephson and I finally
+managed to get around to the Baths, to find them still closed.
+</p>
+
+<p>
+As I was talking with him, a very muddy and dusty car pulled up at the door and
+a young man whose face was marred by the red congested blood vessels that are
+in some a mark of dissipation burst in on us.
+</p>
+
+<p>
+“What—closed up yet—Joe?” he asked. “Haven’t they taken Minturn’s body away?”
+</p>
+
+<p>
+“Yes, it was sent up to Stratfield to-day,” replied the masseur, “but the
+coroner seems to want to worry me all he can.”
+</p>
+
+<p>
+“Too bad. I was up almost all last night, and to-day I have been out in my
+car—tired to death. Thought I might get some rest here. Where are you sending
+the boys—to the Longacre?”
+</p>
+
+<p>
+“Yes. They’ll take good care of you till I open up again. Hope to see you back
+again, then, Mr. Pearcy,” he added, as the young man turned and hurried out to
+his car again. “That was that young Pearcy, you know. Nice boy—but living the
+life too fast. What’s Kennedy doing—anything?”
+</p>
+
+<p>
+I did not like the jaunty bravado of the masseur which now seemed to be
+returning, since nothing definite had taken shape. I determined that he should
+not pump me, as he evidently was trying to do. I had at least fulfilled
+Kennedy’s commission and felt that the sooner I left Josephson the better for
+both of us.
+</p>
+
+<p>
+I was surprised at dinner to receive a wire from Craig saying that he was
+bringing down Dr. Gunther, Mrs. Pearcy and Isabel to New York and asking me to
+have Warner Pearcy and Josephson at the laboratory at nine o’clock.
+</p>
+
+<p>
+By strategy I managed to persuade Pearcy to come, and as for Josephson, he
+could not very well escape, though I saw that as long as nothing more had
+happened, he was more interested in “fixing” the police so that he could resume
+business than anything else.
+</p>
+
+<p>
+As we entered the laboratory that night, Kennedy, who had left his party at a
+downtown hotel to freshen up, met us each at the door. Instead of conducting us
+in front of his laboratory table, which was the natural way, he led us singly
+around through the narrow space back of it.
+</p>
+
+<p>
+I recall that as I followed him, I half imagined that the floor gave way just a
+bit, and there flashed over me, by a queer association of ideas, the
+recollection of having visited an amusement park not long before where merely
+stepping on an innocent-looking section of the flooring had resulted in a
+tremendous knocking and banging beneath, much to the delight of the lovers of
+slap-stick humor. This was serious business, however, and I quickly banished
+the frivolous thought from my mind.
+</p>
+
+<p>
+“The discovery of poison, and its identification,” began Craig at last when we
+had all arrived and were seated about him, “often involves not only the use of
+chemistry but also a knowledge of the chemical effect of the poison on the
+body, and the gross as well as microscopic changes which it produces in various
+tissues and organs—changes, some due to mere contact, others to the actual
+chemicophysiological reaction between the poison and the body.”
+</p>
+
+<p>
+His hand was resting on the poles of a large battery, as he proceeded: “Every
+day the medical detective plays a more and more important part in the detection
+of crime, and I might say that, except in the case of crime complicated by a
+lunacy plea, his work has earned the respect of the courts and of detectives,
+while in the case of insanity the discredit is the fault rather of the law
+itself. The ways in which the doctor can be of use in untangling the facts in
+many forms of crime have become so numerous that the profession of medical
+detective may almost be called a specialty.”
+</p>
+
+<p>
+Kennedy repeated what he had already told me about electrolysis, then placed
+between the poles of the battery a large piece of raw beef.
+</p>
+
+<p>
+He covered the negative electrode with blotting paper and soaked it in a beaker
+near at hand.
+</p>
+
+<p>
+“This solution,” he explained, “is composed of potassium iodide. In this other
+beaker I have a mixture of ordinary starch.”
+</p>
+
+<p>
+He soaked the positive electrode in the starch and then jammed the two against
+the soft red meat. Then he applied the current.
+</p>
+
+<p>
+A few moments later he withdrew the positive electrode. Both it and the meat
+under it were blue!
+</p>
+
+<p>
+“What has happened?” he asked. “The iodine ions have actually passed through
+the beef to the positive pole and the paper on the electrode. Here we have
+starch iodide.”
+</p>
+
+<p>
+It was a startling idea, this of the introduction of a substance by
+electrolysis.
+</p>
+
+<p>
+“I may say,” he resumed, “that the medical view of electricity is changing, due
+in large measure to the genius of the Frenchman, Dr. Leduc. The body, we know,
+is composed largely of water, with salts of soda and potash. It is an excellent
+electrolyte. Yet most doctors regard the introduction of substances by the
+electric current as insignificant or nonexistent. But on the contrary the
+introduction of drugs by electrolysis is regular and far from being
+insignificant may very easily bring about death.
+</p>
+
+<p>
+“That action,” he went on, looking from one of us to another, “may be
+therapeutic, as in the cure for lead poisoning by removing the lead, or it may
+be toxic—as in the case of actually introducing such a poison as strychnine
+into the body by the same forces that will remove the lead.”
+</p>
+
+<p>
+He paused a moment, to enforce the point which had already been suggested. I
+glanced about hastily. If anyone in his little audience was guilty, no one
+betrayed it, for all were following him, fascinated. Yet in the wildly
+throbbing brain of some one of them the guilty knowledge must be seared
+indelibly. Would the mere accusation be enough to dissociate the truth from,
+that brain or would Kennedy have to resort to other means?
+</p>
+
+<p>
+“Some one,” he went on, in a low, tense voice, leaning forward, “some one who
+knew this effect placed strychnine salts on one of the electrodes of the bath
+which Owen Minturn was to use.”
+</p>
+
+<p>
+He did not pause. Evidently he was planning to let the force of his exposure be
+cumulative, until from its sheer momentum it carried everything before it.
+</p>
+
+<p>
+“Walter,” he ordered quickly. “Lend me a hand.”
+</p>
+
+<p>
+Together we moved the laboratory table as he directed.
+</p>
+
+<p>
+There, in the floor, concealed by the shadow, he had placed the same apparatus
+which I had seen him bury in the path between the Pearcy and Minturn estates at
+Stratfield.
+</p>
+
+<p>
+We scarcely breathed.
+</p>
+
+<p>
+“This,” he explained rapidly, “is what is known as a kinograph—the invention of
+Professor HeleShaw of London. It enables me to identify a person by his or her
+walk. Each of you as you entered this room has passed over this apparatus and
+has left a different mark on the paper which registers.”
+</p>
+
+<p>
+For a moment he stopped, as if gathering strength for the final assault.
+</p>
+
+<p>
+“Until late this afternoon I had this kinograph secreted at a certain place in
+Stratfield. Some one had tampered with the leaden water pipes and the electric
+light cable. Fearful that the lead poisoning brought on by electrolysis might
+not produce its result in the intended victim, that person took advantage of
+the new discoveries in electrolysis to complete that work by introducing the
+deadly strychnine during the very process of cure of the lead poisoning.”
+</p>
+
+<p>
+He slapped down a copy of a newspaper. “In the news this morning I told just
+enough of what I had discovered and colored it in such a way that I was sure I
+would arouse apprehension. I did it because I wanted to make the criminal
+revisit the real scene of the crime. There was a double motive now—to remove
+the evidence and to check the spread of the poisoning.”
+</p>
+
+<p>
+He reached over, tore off the paper with a quick, decisive motion, and laid it
+beside another strip, a little discolored by moisture, as though the damp earth
+had touched it.
+</p>
+
+<p>
+“That person, alarmed lest something in the cleverly laid plot, might be
+discovered, went to a certain spot to remove the traces of the diabolical work
+which were hidden there. My kinograph shows the footsteps, shows as plainly as
+if I had been present, the exact person who tried to obliterate the evidence.”
+</p>
+
+<p>
+An ashen pallor seemed to spread over the face of Miss Pearcy, as Kennedy shot
+out the words.
+</p>
+
+<p>
+“That person,” he emphasized, “had planned to put out of the way one who had
+brought disgrace on the Pearcy family. It was an act of private justice.”
+</p>
+
+<p>
+Mrs. Pearcy could stand the strain no longer. She had broken down and was
+weeping incoherently. I strained my ears to catch what she was murmuring. It
+was Minturn’s name, not Gunther’s, that was on her lips.
+</p>
+
+<p>
+“But,” cried Kennedy, raising an accusatory finger from the kinograph tracing
+and pointing it like the finger of Fate itself, “but the self-appointed avenger
+forgot that the leaden water pipe was common to the two houses. Old Mr. Pearcy,
+the wronged, died first. Isabel has guessed the family skeleton—has tried hard
+to shield you, but, Warner Pearcy, you are the murderer!”

+THE EUGENIC BRIDE</h2>
+
+<p>
+Scandal, such as that which Kennedy unearthed in this Pearcy case, was never
+much to his liking, yet he seemed destined, about this period of his career, to
+have a good deal of it.
+</p>
+
+<p>
+We had scarcely finished with the indictment that followed the arrest of young
+Pearcy, when we were confronted by a situation which was as unique as it was
+intensely modern.
+</p>
+
+<p>
+“There’s absolutely no insanity in Eugenia’s family,” I heard a young man
+remark to Kennedy, as my key turned in the lock of the laboratory door.
+</p>
+
+<p>
+For a moment I hesitated about breaking in on a confidential conference, then
+reflected that, as they had probably already heard me at the lock, I had better
+go in and excuse myself.
+</p>
+
+<p>
+As I swung the door open, I saw a young man pacing up and down the laboratory
+nervously, too preoccupied even to notice the slight noise I had made.
+</p>
+
+<p>
+He paused in his nervous walk and faced Kennedy, his back to me.
+</p>
+
+<p>
+“Kennedy,” he said huskily, “I wouldn’t care if there was insanity in her
+family—for, my God!—the tragedy of it all now—I love her!”
+</p>
+
+<p>
+He turned, following Kennedy’s eyes in my direction, and I saw on his face the
+most haggard, haunting look of anxiety that I had ever seen on a young person.
+</p>
+
+<p>
+Instantly I recognized from the pictures I had seen in the newspapers young
+Quincy Atherton, the last of this famous line of the family, who had attracted
+a great deal of attention several months previously by what the newspapers had
+called his search through society for a “eugenics bride,” to infuse new blood
+into the Atherton stock.
+</p>
+
+<p>
+“You need have no fear that Mr. Jameson will be like the other newspaper men,”
+reassured Craig, as he introduced us, mindful of the prejudice which the
+unpleasant notoriety of Atherton’s marriage had already engendered in his mind.
+</p>
+
+<p>
+I recalled that when I had first heard of Atherton’s “eugenic marriage,” I had
+instinctively felt a prejudice against the very idea of such cold, calculating,
+materialistic, scientific mating, as if one of the last fixed points were
+disappearing in the chaos of the social and sex upheaval.
+</p>
+
+<p>
+Now, I saw that one great fact of life must always remain. We might ride in
+hydroaeroplanes, delve into the very soul by psychanalysis, perhaps even run
+our machines by the internal forces of radium—even marry according to Galton or
+Mendel. But there would always be love, deep passionate love of the man for the
+woman, love which all the discoveries of science might perhaps direct a little
+less blindly, but the consuming flame of which not all the coldness of science
+could ever quench. No tampering with the roots of human nature could ever
+change the roots.
+</p>
+
+<p>
+I must say that I rather liked young Atherton. He had a frank, open face, the
+most prominent feature of which was his somewhat aristocratic nose. Otherwise
+he impressed one as being the victim of heredity in faults, if at all serious,
+against which he was struggling heroically.
+</p>
+
+<p>
+It was a most pathetic story which he told, a story of how his family had
+degenerated from the strong stock of his ancestors until he was the last of the
+line. He told of his education, how he had fallen, a rather wild youth bent in
+the footsteps of his father who had been a notoriously good clubfellow, under
+the influence of a college professor, Dr. Crafts, a classmate of his father’s,
+of how the professor had carefully and persistently fostered in him an idea
+that had completely changed him.
+</p>
+
+<p>
+“Crafts always said it was a case of eugenics against euthenics,” remarked
+Atherton, “of birth against environment. He would tell me over and over that
+birth gave me the clay, and it wasn’t such bad clay after all, but that
+environment would shape the vessel.”
+</p>
+
+<p>
+Then Atherton launched into a description of how he had striven to find a girl
+who had the strong qualities his family germ plasm seemed to have lost, mainly,
+I gathered, resistance to a taint much like manic depressive insanity. And as
+he talked, it was borne in on me that, after all, contrary to my first
+prejudice, there was nothing very romantic indeed about disregarding the plain
+teachings of science on the subject of marriage and one’s children.
+</p>
+
+<p>
+In his search for a bride, Dr. Crafts, who had founded a sort of Eugenics
+Bureau, had come to advise him. Others may have looked up their brides in
+Bradstreet’s, or at least the Social Register. Atherton had gone higher, had
+been overjoyed to find that a girl he had met in the West, Eugenia Gilman,
+measured up to what his friend told him were the latest teachings of science.
+He had been overjoyed because, long before Crafts had told him, he had found
+out that he loved her deeply.
+</p>
+
+<p>
+“And now,” he went on, half choking with emotion, “she is apparently suffering
+from just the same sort of depression as I myself might suffer from if the
+recessive trait became active.”
+</p>
+
+<p>
+“What do you mean, for instance?” asked Craig.
+</p>
+
+<p>
+“Well, for one thing, she has the delusion that my relatives are persecuting
+her.”
+</p>
+
+<p>
+“Persecuting her?” repeated Craig, stifling the remark that that was not in
+itself a new thing in this or any other family. “How?”
+</p>
+
+<p>
+“Oh, making her feel that, after all, it is Atherton family rather than Gilman
+health that counts—little remarks that when our baby is born, they hope it will
+resemble Quincy rather than Eugenia, and all that sort of thing, only worse and
+more cutting, until the thing has begun to prey on her mind.”
+</p>
+
+<p>
+“I see,” remarked Kennedy thoughtfully. “But don’t you think this is a case for
+a—a doctor, rather than a detective?”
+</p>
+
+<p>
+Atherton glanced up quickly. “Kennedy,” he answered slowly, “where millions of
+dollars are involved, no one can guess to what lengths the human mind will
+go—no one, except you.”
+</p>
+
+<p>
+“Then you have suspicions of something worse?”
+</p>
+
+<p>
+“Y-yes—but nothing definite. Now, take this case. If I should die childless,
+after my wife, the Atherton estate would descend to my nearest relative,
+Burroughs Atherton, a cousin.”
+</p>
+
+<p>
+“Unless you willed it to—”
+</p>
+
+<p>
+“I have already drawn a will,” he interrupted, “and in case I survive Eugenia
+and die childless, the money goes to the founding of a larger Eugenics Bureau,
+to prevent in the future, as much as possible, tragedies such as this of which
+I find myself a part. If the case is reversed, Eugenia will get her third and
+the remainder will go to the Bureau or the Foundation, as I call the new
+venture. But,” and here young Atherton leaned forward and fixed his large eyes
+keenly on us, “Burroughs might break the will. He might show that I was of
+unsound mind, or that Eugenia was, too.”
+</p>
+
+<p>
+“Are there no other relatives?”
+</p>
+
+<p>
+“Burroughs is the nearest,” he replied, then added frankly, “I have a second
+cousin, a young lady named Edith Atherton, with whom both Burroughs and I used
+to be very friendly.”
+</p>
+
+<p>
+It was evident from the way he spoke that he had thought a great deal about
+Edith Atherton, and still thought well of her.
+</p>
+
+<p>
+“Your wife thinks it is Burroughs who is persecuting her?” asked Kennedy.
+</p>
+
+<p>
+Atherton shrugged his shoulders.
+</p>
+
+<p>
+“Does she get along badly with Edith? She knows her I presume?”
+</p>
+
+<p>
+“Of course. The fact is that since the death of her mother, Edith has been
+living with us. She is a splendid girl, and all alone in the world now, and I
+had hopes that in New York she might meet some one and marry well.”
+</p>
+
+<p>
+Kennedy was looking squarely at Atherton, wondering whether he might ask a
+question without seeming impertinent. Atherton caught the look, read it, and
+answered quite frankly, “To tell the truth, I suppose I might have married
+Edith, before I met Eugenia, if Professor Crafts had not dissuaded me. But it
+wouldn’t have been real love—nor wise. You know,” he went on more frankly, now
+that the first hesitation was over and he realized that if he were to gain
+anything at all by Kennedy’s services, there must be the utmost candor between
+them, “you know cousins may marry if the stocks are known to be strong. But if
+there is a defect, it is almost sure to be intensified. And so I—I gave up the
+idea—never had it, in fact, so strongly as to propose to her. And when I met
+Eugenia all the Athertons on the family tree couldn’t have bucked up against
+the combination.”
+</p>
+
+<p>
+He was deadly in earnest as he arose from the chair into which he had dropped
+after I came in.
+</p>
+
+<p>
+“Oh, it’s terrible—this haunting fear, this obsession that I have had, that, in
+spite of all I have tried to do, some one, somehow, will defeat me. Then comes
+the situation, just at a time when Eugenia and I feel that we have won against
+Fate, and she in particular needs all the consideration and care in the
+world—and—and I am defeated.”
+</p>
+
+<p>
+Atherton was again pacing the laboratory.
+</p>
+
+<p>
+“I have my car waiting outside,” he pleaded. “I wish you would go with me to
+see Eugenia—now.”
+</p>
+
+<p>
+It was impossible to resist him. Kennedy rose and I followed, not without a
+trace of misgiving.
+</p>
+
+<p>
+The Atherton mansion was one of the old houses of the city, a somber stone
+dwelling with a garden about it on a downtown square, on which business was
+already encroaching. We were admitted by a servant who seemed to walk over the
+polished floors with stealthy step as if there was something sacred about even
+the Atherton silence. As we waited in a high-ceilinged drawing-room with
+exquisite old tapestries on the walls, I could not help feeling myself the
+influence of wealth and birth that seemed to cry out from every object of art
+in the house.
+</p>
+
+<p>
+On the longer wall of the room, I saw a group of paintings. One, I noted
+especially, must have been Atherton’s ancestor, the founder of the line. There
+was the same nose in Atherton, for instance, a striking instance of heredity. I
+studied the face carefully. There was every element of strength in it, and I
+thought instinctively that, whatever might have been the effects of in-breeding
+and bad alliances, there must still be some of that strength left in the
+present descendant of the house of Atherton. The more I thought about the
+house, the portrait, the whole case, the more unable was I to get out of my
+head a feeling that though I had not been in such a position before, I had at
+least read or heard something of which it vaguely reminded me.
+</p>
+
+<p>
+Eugenia Atherton was reclining listlessly in her room in a deep leather easy
+chair, when Atherton took us up at last. She did not rise to greet us, but I
+noted that she was attired in what Kennedy once called, as we strolled up the
+Avenue, “the expensive sloppiness of the present styles.” In her case the
+looseness with which her clothes hung was exaggerated by the lack of energy
+with which she wore them.
+</p>
+
+<p>
+She had been a beautiful girl, I knew. In fact, one could see that she must
+have been. Now, however, she showed marks of change. Her eyes were large, and
+protruding, not with the fire of passion which is often associated with large
+eyes, but dully, set in a puffy face, a trifle florid. Her hands seemed, when
+she moved them, to shake with an involuntary tremor, and in spite of the fact
+that one almost could feel that her heart and lungs were speeding with energy,
+she had lost weight and no longer had the full, rounded figure of health. Her
+manner showed severe mental disturbance, indifference, depression, a
+distressing deterioration. All her attractive Western breeziness was gone. One
+felt the tragedy of it only too keenly.
+</p>
+
+<p>
+“I have asked Professor Kennedy, a specialist, to call, my dear,” said Atherton
+gently, without mentioning what the specialty was.
+</p>
+
+<p>
+“Another one?” she queried languorously.
+</p>
+
+<p>
+There was a colorless indifference in the tone which was almost tragic. She
+said the words slowly and deliberately, as though even her mind worked that
+way.
+</p>
+
+<p>
+From the first, I saw that Kennedy had been observing Eugenia Atherton keenly.
+And in the role of specialist in nervous diseases he was enabled to do what
+otherwise would have been difficult to accomplish.
+</p>
+
+<p>
+Gradually, from observing her mental condition of indifference which made
+conversation extremely difficult as well as profitless, he began to consider
+her physical condition. I knew him well enough to gather from his manner alone
+as he went on that what had seemed at the start to be merely a curious case,
+because it concerned the Athertons, was looming up in his mind as unusual in
+itself, and was interesting him because it baffled him.
+</p>
+
+<p>
+Craig had just discovered that her pulse was abnormally high, and that
+consequently she had a high temperature, and was sweating profusely.
+</p>
+
+<p>
+“Would you mind turning your head, Mrs. Atherton?” he asked.
+</p>
+
+<p>
+She turned slowly, half way, her eyes fixed vacantly on the floor until we
+could see the once striking profile.
+</p>
+
+<p>
+“No, all the way around, if you please,” added Kennedy.
+</p>
+
+<p>
+She offered no objection, not the slightest resistance. As she turned her head
+as far as she could, Kennedy quickly placed his forefinger and thumb gently on
+her throat, the once beautiful throat, now with skin harsh and rough. Softly he
+moved his fingers just a fraction of an inch over the so-called “Adam’s apple”
+and around it for a little distance.
+</p>
+
+<p>
+“Thank you,” he said. “Now around to the other side.”
+</p>
+
+<p>
+He made no other remark as he repeated the process, but I fancied I could tell
+that he had had an instant suspicion of something the moment he touched her
+throat.
+</p>
+
+<p>
+He rose abstractedly, bowed, and we started to leave the room, uncertain
+whether she knew or cared. Quincy had fixed his eyes silently on Craig, as if
+imploring him to speak, but I knew how unlikely that was until he had confirmed
+his suspicion to the last slightest detail.
+</p>
+
+<p>
+We were passing through a dressing room in the suite when we met a tall young
+woman, whose face I instantly recognized, not because I had ever seen it
+before, but because she had the Atherton nose so prominently developed.
+</p>
+
+<p>
+“My cousin, Edith,” introduced Quincy.
+</p>
+
+<p>
+We bowed and stood for a moment chatting. There seemed to be no reason why we
+should leave the suite, since Mrs. Atherton paid so little attention to us even
+when we had been in the same room. Yet a slight movement in her room told me
+that in spite of her lethargy she seemed to know that we were there and to
+recognize who had joined us.
+</p>
+
+<p>
+Edith Atherton was a noticeable woman, a woman of temperament, not beautiful
+exactly, but with a stateliness about her, an aloofness. The more I studied her
+face, with its thin sensitive lips and commanding, almost imperious eyes, the
+more there seemed to be something peculiar about her. She was dressed very
+simply in black, but it was the simplicity that costs. One thing was quite
+evident—her pride in the family of Atherton.
+</p>
+
+<p>
+And as we talked, it seemed to be that she, much more than Eugenia in her
+former blooming health, was a part of the somber house. There came over me
+again the impression I had received before that I had read or heard something
+like this case before.
+</p>
+
+<p>
+She did not linger long, but continued her stately way into the room where
+Eugenia sat. And at once it flashed over me what my impression, indefinable,
+half formed, was. I could not help thinking, as I saw her pass, of the lady
+Madeline in “The Fall of the House of Usher.”
+</p>

+<h2><a name="chap32"></a>CHAPTER XXXII<br/>
+THE GERM PLASM</h2>
+
+<p>
+I regarded her with utter astonishment and yet found it impossible to account
+for such a feeling. I looked at Atherton, but on his face I could see nothing
+but a sort of questioning fear that only increased my illusion, as if he, too,
+had only a vague, haunting premonition of something terrible impending. Almost
+I began to wonder whether the Atherton house might not crumble under the
+fierceness of a sudden whirlwind, while the two women in this case, one
+representing the wasted past, the other the blasted future, dragged Atherton
+down, as the whole scene dissolved into some ghostly tarn. It was only for a
+moment, and then I saw that the more practical Kennedy had been examining some
+bottles on the lady’s dresser before which we had paused.
+</p>
+
+<p>
+One was a plain bottle of pellets which might have been some homeopathic
+remedy.
+</p>
+
+<p>
+“Whatever it is that is the matter with Eugenia,” remarked Atherton, “it seems
+to have baffled the doctors so far.”
+</p>
+
+<p>
+Kennedy said nothing, but I saw that he had clumsily overturned the bottle and
+absently set it up again, as though his thoughts were far away. Yet with a
+cleverness that would have done credit to a professor of legerdemain he had
+managed to extract two or three of the pellets.
+</p>
+
+<p>
+“Yes,” he said, as he moved slowly toward the staircase in the wide hall, “most
+baffling.”
+</p>
+
+<p>
+Atherton was plainly disappointed. Evidently he had expected Kennedy to arrive
+at the truth and set matters right by some sudden piece of wizardry, and it was
+with difficulty that he refrained from saying so.
+</p>
+
+<p>
+“I should like to meet Burroughs Atherton,” he remarked as we stood in the wide
+hall on the first floor of the big house. “Is he a frequent visitor?”
+</p>
+
+<p>
+“Not frequent,” hastened Quincy Atherton, in a tone that showed some
+satisfaction in saying it. “However, by a lucky chance he has promised to call
+to-night—a mere courtesy, I believe, to Edith, since she has come to town on a
+visit.”
+</p>
+
+<p>
+“Good!” exclaimed Kennedy. “Now, I leave it to you, Atherton, to make some
+plausible excuse for our meeting Burroughs here.”
+</p>
+
+<p>
+“I can do that easily.”
+</p>
+
+<p>
+“I shall be here early,” pursued Kennedy as we left.
+</p>
+
+<p>
+Back again in the laboratory to which Atherton insisted on accompanying us in
+his car, Kennedy busied himself for a few minutes, crushing up one of the
+tablets and trying one or two reactions with some of the powder dissolved,
+while I looked on curiously.
+</p>
+
+<p>
+“Craig,” I remarked contemplatively, after a while, “how about Atherton
+himself? Is he really free from the—er—stigmata, I suppose you call them, of
+insanity?”
+</p>
+
+<p>
+“You mean, may the whole trouble lie with him?” he asked, not looking up from
+his work.
+</p>
+
+<p>
+“Yes—and the effect on her be a sort of reflex, say, perhaps the effect of
+having sold herself for money and position. In other words, does she, did she,
+ever love him? We don’t know that. Might it not prey on her mind, until with
+the kind help of his precious relatives even Nature herself could not stand the
+strain—especially in the delicate condition in which she now finds herself?”
+</p>
+
+<p>
+I must admit that I felt the utmost sympathy for the poor girl whom we had just
+seen such a pitiable wreck.
+</p>
+
+<p>
+Kennedy closed his eyes tightly until they wrinkled at the corners.
+</p>
+
+<p>
+“I think I have found out the immediate cause of her trouble,” he said simply,
+ignoring my suggestion.
+</p>
+
+<p>
+“What is it?” I asked eagerly.
+</p>
+
+<p>
+“I can’t imagine how they could have failed to guess it, except that they never
+would have suspected to look for anything resembling exophthalmic goiter in a
+person of her stamina,” he answered, pronouncing the word slowly. “You have
+heard of the thyroid gland in the neck?”
+</p>
+
+<p>
+“Yes?” I queried, for it was a mere name to me.
+</p>
+
+<p>
+“It is a vascular organ lying under the chin with a sort of little isthmus
+joining the two parts on either side of the windpipe,” he explained. “Well,
+when there is any deterioration of those glands through any cause, all sorts of
+complications may arise. The thyroid is one of the so-called ductless glands,
+like the adrenals above the kidneys, the pineal gland and the pituitary body.
+In normal activity they discharge into the blood substances which are carried
+to other organs and are now known to be absolutely essential.
+</p>
+
+<p>
+“The substances which they secrete are called ‘hormones’—those chemical
+messengers, as it were, by which many of the processes of the body are
+regulated. In fact, no field of experimental physiology is richer in interest
+than this. It seems that few ordinary drugs approach in their effects on
+metabolism the hormones of the thyroid. In excess they produce such diseases as
+exophthalmic goiter, and goiter is concerned with the enlargement of the glands
+and surrounding tissues beyond anything like natural size. Then, too, a defect
+in the glands causes the disease known as myxedema in adults and cretinism in
+children. Most of all, the gland seems to tell on the germ plasm of the body,
+especially in women.”
+</p>
+
+<p>
+I listened in amazement, hardly knowing what to think. Did his discovery
+portend something diabolical, or was it purely a defect in nature which Dr.
+Crafts of the Eugenics Bureau had overlooked?
+</p>
+
+<p>
+“One thing at a time, Walter,” cautioned Kennedy, when I put the question to
+him, scarcely expecting an answer yet.
+</p>
+
+<p>
+That night in the old Atherton mansion, while we waited for Borroughs to
+arrive, Kennedy, whose fertile mind had contrived to kill at least two birds
+with one stone, busied himself by cutting in on the regular telephone line and
+placing an extension of his own in a closet in the library. To it he attached
+an ordinary telephone receiver fastened to an arrangement which was strange to
+me. As nearly as I can describe it, between the diaphragm of the regular
+receiver and a brownish cylinder, like that of a phonograph, and with a needle
+attached, was fitted an air chamber of small size, open to the outer air by a
+small hole to prevent compression.
+</p>
+
+<p>
+The work was completed expeditiously, but we had plenty of time to wait, for
+Borroughs Atherton evidently did not consider that an evening had fairly begun
+until nine o’clock.
+</p>
+
+<p>
+He arrived at last, however, rather tall, slight of figure, narrow-shouldered,
+designed for the latest models of imported fabrics. It was evident merely by
+shaking hands with Burroughs that he thought both the Athertons and the
+Burroughses just the right combination. He was one of those few men against
+whom I conceive an instinctive prejudice, and in this case I felt positive
+that, whatever faults the Atherton germ plasm might contain, he had combined
+others from the determiners of that of the other ancestors he boasted. I could
+not help feeling that Eugenia Atherton was in about as unpleasant an atmosphere
+of social miasma as could be imagined.
+</p>
+
+<p>
+Burroughs asked politely after Eugenia, but it was evident that the real
+deference was paid to Edith Atherton and that they got along very well
+together. Burroughs excused himself early, and we followed soon after.
+</p>
+
+<p>
+“I think I shall go around to this Eugenics Bureau of Dr. Crafts,” remarked
+Kennedy the next day, after a night’s consideration of the case.
+</p>
+
+<p>
+The Bureau occupied a floor in a dwelling house uptown which had been remodeled
+into an office building. Huge cabinets were stacked up against the walls, and
+in them several women were engaged in filing blanks and card records. Another
+part of the office consisted of an extensive library on eugenic subjects.
+</p>
+
+<p>
+Dr. Crafts, in charge of the work, whom we found in a little office in front
+partitioned off by ground glass, was an old man with an alert, vigorous mind on
+whom the effects of plain living and high thinking showed plainly. He was
+looking over some new blanks with a young woman who seemed to be working with
+him, directing the force of clerks as well as the “field workers,” who were
+gathering the vast mass of information which was being studied. As we
+introduced ourselves, he introduced Dr. Maude Schofield.
+</p>
+
+<p>
+“I have heard of your eugenic marriage contests,” began Kennedy, “more
+especially of what you have done for Mr. Quincy Atherton.”
+</p>
+
+<p>
+“Well—not exactly a contest in that case, at least,” corrected Dr. Crafts with
+an indulgent smile for a layman.
+</p>
+
+<p>
+“No,” put in Dr. Schofield, “the Eugenics Bureau isn’t a human stock farm.”
+</p>
+
+<p>
+“I see,” commented Kennedy, who had no such idea, anyhow. He was always lenient
+with anyone who had what he often referred to as the “illusion of grandeur.”
+</p>
+
+<p>
+“We advise people sometimes regarding the desirability or the undesirability of
+marriage,” mollified Dr. Crafts. “This is a sort of clearing house for
+scientific race investigation and improvement.”
+</p>
+
+<p>
+“At any rate,” persisted Kennedy, “after investigation, I understand, you
+advised in favor of his marriage with Miss Gilman.”
+</p>
+
+<p>
+“Yes, Eugenia Gilman seemed to measure well up to the requirements in such a
+match. Her branch of the Gilmans has always been of the vigorous, pioneering
+type, as well as intellectual. Her father was one of the foremost thinkers in
+the West; in fact had long held ideas on the betterment of the race. You see
+that in the choice of a name for his daughter—Eugenia.”
+</p>
+
+<p>
+“Then there were no recessive traits in her family,” asked Kennedy quickly, “of
+the same sort that you find in the Athertons?”
+</p>
+
+<p>
+“None that we could discover,” answered Dr. Crafts positively.
+</p>
+
+<p>
+“No epilepsy, no insanity of any form?”
+</p>
+
+<p>
+“No. Of course, you understand that almost no one is what might be called
+eugenically perfect. Strictly speaking, perhaps not over two or three per cent.
+of the population even approximates that standard. But it seemed to me that in
+everything essential in this case, weakness latent in Atherton was mating
+strength in Eugenia and the same way on her part for an entirely different set
+of traits.”
+</p>
+
+<p>
+“Still,” considered Kennedy, “there might have been something latent in her
+family germ plasm back of the time through which you could trace it?”
+</p>
+
+<p>
+Dr. Crafts shrugged his shoulders. “There often is, I must admit, something we
+can’t discover because it lies too far back in the past.”
+</p>
+
+<p>
+“And likely to crop out after skipping generations,” put in Maude Schofield.
+</p>
+
+<p>
+She evidently did not take the same liberal view in the practical application
+of the matter expressed by her chief. I set it down to the ardor of youth in a
+new cause, which often becomes the saner conservatism of maturity.
+</p>
+
+<p>
+“Of course, you found it much easier than usual to get at the true family
+history of the Athertons,” pursued Kennedy. “It is an old family and has been
+prominent for generations.”
+</p>
+
+<p>
+“Naturally,” assented Dr. Crafts.
+</p>
+
+<p>
+“You know Burroughs Atherton on both lines of descent?” asked Kennedy, changing
+the subject abruptly.
+</p>
+
+<p>
+“Yes, fairly well,” answered Crafts.
+</p>
+
+<p>
+“Now, for example,” went on Craig, “how would you advise him to marry?”
+</p>
+
+<p>
+I saw at once that he was taking this subterfuge as a way of securing
+information which might otherwise have been withheld if asked for directly.
+Maude Schofield also saw it, I fancied, but this time said nothing. “They had a
+grandfather who was a manic depressive on the Atherton side,” said Crafts
+slowly. “Now, no attempt has ever been made to breed that defect out of the
+family. In the case of Burroughs, it is perhaps a little worse, for the other
+side of his ancestry is not free from the taint of alcoholism.”
+</p>
+
+<p>
+“And Edith Atherton?”
+</p>
+
+<p>
+“The same way. They both carry it. I won’t go into the Mendelian law on the
+subject. We are clearing up much that is obscure. But as to Burroughs, he
+should marry, if at all, some one without that particular taint. I believe that
+in a few generations by proper mating most taints might be bred out of
+families.”
+</p>
+
+<p>
+Maude Schofield evidently did not agree with Dr. Crafts on some point, and,
+noticing it, he seemed to be in the position both of explaining his contention
+to us and of defending it before his fair assistant.
+</p>
+
+<p>
+“It is my opinion, as far as I have gone with the data,” he added, “that there
+is hope for many of those whose family history shows certain nervous taints. A
+sweeping prohibition of such marriages would be futile, perhaps injurious. It
+is necessary that the mating be carefully made, however, to prevent
+intensifying the taint. You see, though I am a eugenist I am not an extremist.”
+</p>
+
+<p>
+He paused, then resumed argumentatively: “Then there are other questions, too,
+like that of genius with its close relation to manic depressive insanity. Also,
+there is decrease enough in the birth rate, without adding an excuse for it.
+No, that a young man like Atherton should take the subject seriously, instead
+of spending his time in wild dissipation, like his father, is certainly
+creditable, argues in itself that there still must exist some strength in his
+stock.
+</p>
+
+<p>
+“And, of course,” he continued warmly, “when I say that weakness in a trait—not
+in all traits, by any means—should marry strength and that strength may marry
+weakness, I don’t mean that all matches should be like that. If we are too
+strict we may prohibit practically all marriages. In Atherton’s case, as in
+many another, I felt that I should interpret the rule as sanely as possible.”
+</p>
+
+<p>
+“Strength should marry strength, and weakness should never marry,” persisted
+Maude Schofield. “Nothing short of that will satisfy the true eugenist.”
+</p>
+
+<p>
+“Theoretically,” objected Crafts. “But Atherton was going to marry, anyhow. The
+only thing for me to do was to lay down a rule which he might follow safely.
+Besides, any other rule meant sure disaster.”
+</p>
+
+<p>
+“It was the only rule with half a chance of being followed and at any rate,”
+drawled Kennedy, as the eugenists wrangled, “what difference does it make in
+this case? As nearly as I can make out it is Mrs. Atherton herself, not
+Atherton, who is ill.”
+</p>
+
+<p>
+Maude Schofield had risen to return to supervising a clerk who needed help. She
+left us, still unconvinced.
+</p>
+
+<p>
+“That is a very clever girl,” remarked Kennedy as she shut the door and he
+scanned Dr. Crafts’ face dosely.
+</p>
+
+<p>
+“Very,” assented the Doctor.
+</p>
+
+<p>
+“The Schofields come of good stock?” hazarded Kennedy.
+</p>
+
+<p>
+“Very,” assented Dr. Crafts again.
+</p>
+
+<p>
+Evidently he did not care to talk about individual cases, and I felt that the
+rule was a safe one, to prevent Eugenics from becoming Gossip. Kennedy thanked
+him for his courtesy, and we left apparently on the best of terms both with
+Crafts and his assistant.

+THE SEX CONTROL</h2>
+
+<p>
+I did not see Kennedy again that day until late in the afternoon, when he came
+into the laboratory carrying a small package.
+</p>
+
+<p>
+“Theory is one thing, practice is another,” he remarked, as he threw his hat
+and coat into a chair.
+</p>
+
+<p>
+“Which means—in this case?” I prompted.
+</p>
+
+<p>
+“Why, I have just seen Atherton. Of course I didn’t repeat our conversation of
+this morning, and I’m glad I didn’t. He almost makes me think you are right,
+Walter. He’s obsessed by the fear of Burroughs. Why, he even told me that
+Burroughs had gone so far as to take a leaf out of his book, so to speak, get
+in touch with the Eugenics Bureau as if to follow his footsteps, but really to
+pump them about Atherton himself. Atherton says it’s all Burroughs’ plan to
+break his will and that the fellow has even gone so far as to cultivate the
+acquaintance of Maude Schofield, knowing that he will get no sympathy from
+Crafts.”
+</p>
+
+<p>
+“First it was Edith Atherton, now it is Maude Schofield that he hitches up with
+Burroughs,” I commented. “Seems to me that I have heard that one of the first
+signs of insanity is belief that everyone about the victim is conspiring
+against him. I haven’t any love for any of them—but I must be fair.”
+</p>
+
+<p>
+“Well,” said Kennedy, unwrapping the package, “there <i>is</i> this much to it.
+Atherton says Burroughs and Maude Schofield have been seen together more than
+once—and not at intellectual gatherings either. Burroughs is a fascinating
+fellow to a woman, if he wants to be, and the Schofields are at least the
+social equals of the Burroughs. Besides,” he added, “in spite of eugenics,
+feminism, and all the rest—sex, like murder, will out. There’s no use having
+any false ideas about <i>that</i>. Atherton may see red—but, then, he was quite
+excited.”
+</p>
+
+<p>
+“Over what?” I asked, perplexed more than ever at the turn of events.
+</p>
+
+<p>
+“He called me up in the first place. ‘Can’t you do something?’ he implored.
+‘Eugenia is getting worse all the time.’ She is, too. I saw her for a moment,
+and she was even more vacant than yesterday.”
+</p>
+
+<p>
+The thought of the poor girl in the big house somehow brought over me again my
+first impression of Poe’s story.
+</p>
+
+<p>
+Kennedy had unwrapped the package which proved to be the instrument he had left
+in the closet at Atherton’s. It was, as I had observed, like an ordinary wax
+cylinder phonograph record.
+</p>
+
+<p>
+“You see,” explained Kennedy, “it is nothing more than a successful application
+at last of, say, one of those phonographs you have seen in offices for taking
+dictation, placed so that the feebler vibrations of the telephone affect it.
+Let us see what we have here.”
+</p>
+
+<p>
+He had attached the cylinder to an ordinary phonograph, and after a number of
+routine calls had been run off, he came to this, in voices which we could only
+guess at but not recognize, for no names were used.
+</p>
+
+<p>
+“How is she to-day?”
+</p>
+
+<p>
+“Not much changed—perhaps not so well.”
+</p>
+
+<p>
+“It’s all right, though. That is natural. It is working well. I think you might
+increase the dose, one tablet.”
+</p>
+
+<p>
+“You’re sure it is all right?” (with anxiety).
+</p>
+
+<p>
+“Oh, positively—it has been done in Europe.”
+</p>
+
+<p>
+“I hope so. It must be a boy—and an <i>Atherton</i>.”
+</p>
+
+<p>
+“Never fear.”
+</p>
+
+<p class="p2">
+That was all. Who was it? The voices were unfamiliar to me, especially when
+repeated mechanically. Besides they may have been disguised. At any rate we had
+learned something. Some one was trying to control the sex of the expected
+Atherton heir. But that was about all. Who it was, we knew no better,
+apparently, than before.
+</p>
+
+<p>
+Kennedy did not seem to care much, however. Quickly he got Quincy Atherton on
+the wire and arranged for Atherton to have Dr. Crafts meet us at the house at
+eight o’clock that night, with Maude Schofield. Then he asked that Burroughs
+Atherton be there, and of course, Edith and Eugenia.
+</p>
+
+<p>
+We arrived almost as the clock was striking, Kennedy carrying the phonograph
+record and another blank record, and a boy tugging along the machine itself.
+Dr. Crafts was the next to appear, expressing surprise at meeting us, and I
+thought a bit annoyed, for he mentioned that it had been with reluctance that
+he had had to give up some work he had planned for the evening. Maude
+Schofield, who came with him, looked bored. Knowing that she disapproved of the
+match with Eugenia, I was not surprised. Burroughs arrived, not as late as I
+had expected, but almost insultingly supercilious at finding so many strangers
+at what Atherton had told him was to be a family conference, in order to get
+him to come. Last of all Edith Atherton descended the staircase, the
+personification of dignity, bowing to each with a studied graciousness, as if
+distributing largess, but greeting Burroughs with an air that plainly showed
+how much thicker was blood than water. Eugenia remained upstairs, lethargic,
+almost cataleptic, as Atherton told us when we arrived.
+</p>
+
+<p>
+“I trust you are not going to keep us long, Quincy,” yawned Burroughs, looking
+ostentatiously at his watch.
+</p>
+
+<p>
+“Only long enough for Professor Kennedy to say a few words about Eugenia,”
+replied Atherton nervously, bowing to Kennedy.
+</p>
+
+<p>
+Kennedy cleared his throat slowly.
+</p>
+
+<p>
+“I don’t know that I have much to say,” began Kennedy, still seated. “I suppose
+Mr. Atherton has told you I have been much interested in the peculiar state of
+health of Mrs. Atherton?”
+</p>
+
+<p>
+No one spoke, and he went on easily: “There is something I might say, however,
+about the—er—what I call the chemistry of insanity. Among the present wonders
+of science, as you doubtless know, none stirs the imagination so powerfully as
+the doctrine that at least some forms of insanity are the result of chemical
+changes in the blood. For instance, ill temper, intoxication, many things are
+due to chemical changes in the blood acting on the brain.
+</p>
+
+<p>
+“Go further back. Take typhoid fever with its delirium, influenza with its
+suicide mania. All due to toxins—poisons. Chemistry—chemistry—all of them
+chemistry.”
+</p>
+
+<p>
+Craig had begun carefully so as to win their attention. He had it as he went
+on: “Do we not brew within ourselves poisons which enter the circulation and
+pervade the system? A sudden emotion upsets the chemistry of the body. Or
+poisonous food. Or a drug. It affects many things. But we could never have had
+this chemical theory unless we had had physiological chemistry—and some carry
+it so far as to say that the brain secretes thought, just as the liver secretes
+bile, that thoughts are the results of molecular changes.”
+</p>
+
+<p>
+“You are, then, a materialist of the most pronounced type,” asserted Dr.
+Crafts.
+</p>
+
+<p>
+Kennedy had been reaching over to a table, toying with the phonograph. As
+Crafts spoke he moved a key, and I suspected that it was in order to catch the
+words.
+</p>
+
+<p>
+“Not entirely,” he said. “No more than some eugenists.”
+</p>
+
+<p>
+“In our field,” put in Maude Schofield, “I might express the thought this
+way—the sociologist has had his day; now it is the biologist, the eugenist.”
+</p>
+
+<p>
+“That expresses it,” commented Kennedy, still tinkering with the record. “Yet
+it does not mean that because we have new ideas, they abolish the old. Often
+they only explain, amplify, supplement. For instance,” he said, looking up at
+Edith Atherton, “take heredity. Our knowledge seems new, but is it? Marriages
+have always been dictated by a sort of eugenics. Society is founded on that.”
+</p>
+
+<p>
+“Precisely,” she answered. “The best families have always married into the best
+families. These modern notions simply recognize what the best people have
+always thought—except that it seems to me,” she added with a sarcastic
+flourish, “people of no ancestry are trying to force themselves in among their
+betters.”
+</p>
+
+<p>
+“Very true, Edith,” drawled Burroughs, “but we did not have to be brought here
+by Quincy to learn that.”
+</p>
+
+<p>
+Quincy Atherton had risen during the discussion and had approached Kennedy.
+Craig continued to finger the phonograph abstractedly, as he looked up.
+</p>
+
+<p>
+“About this—this insanity theory,” he whispered eagerly. “You think that the
+suspicions I had have been justified?”
+</p>
+
+<p>
+I had been watching Kennedy’s hand. As soon as Atherton had started to speak, I
+saw that Craig, as before, had moved the key, evidently registering what he
+said, as he had in the case of the others during the discussion.
+</p>
+
+<p>
+“One moment, Atherton,” he whispered in reply, “I’m coming to that. Now,” he
+resumed aloud, “there is a disease, or a number of diseases, to which my
+remarks about insanity a while ago might apply very well. They have been known
+for some time to arise from various affections of the thyroid glands in the
+neck. These glands, strange to say, if acted on in certain ways can cause
+degenerations of mind and body, which are well known, but in spite of much
+study are still very little understood. For example, there is a definite
+interrelation between them and sex—especially in woman.”
+</p>
+
+<p>
+Rapidly he sketched what he had already told me of the thyroid and the
+hormones. “These hormones,” added Kennedy, “are closely related to many
+reactions in the body, such as even the mother’s secretion of milk at the
+proper time and then only. That and many other functions are due to the
+presence and character of these chemical secretions from the thyroid and other
+ductless glands. It is a fascinating study. For we know that anything that will
+upset—reduce or increase—the hormones is a matter intimately concerned with
+health. Such changes,” he said earnestly, leaning forward, “might be aimed
+directly at the very heart of what otherwise would be a true eugenic marriage.
+It is even possible that loss of sex itself might be made to follow deep
+changes of the thyroid.”
+</p>
+
+<p>
+He stopped a moment. Even if he had accomplished nothing else he had struck a
+note which had caused the Athertons to forget their former superciliousness.
+</p>
+
+<p>
+“If there is an oversupply of thyroid hormones,” continued Craig, “that excess
+will produce many changes, for instance a condition very much like exophthalmic
+goiter. And,” he said, straightening up, “I find that Eugenia Atherton has
+within her blood an undue proportion of these thyroid hormones. Now, is it
+overfunction of the glands, hyper-secretion—or is it something else?”
+</p>
+
+<p>
+No one moved as Kennedy skillfully led his disclosure along step by step.
+</p>
+
+<p>
+“That question,” he began again slowly, shifting his position in the chair,
+“raises in my mind, at least, a question which has often occurred to me before.
+Is it possible for a person, taking advantage of the scientific knowledge we
+have gained, to devise and successfully execute a murder without fear of
+discovery? In other words, can a person be removed with that technical nicety
+of detail which will leave no clue and will be set down as something entirely
+natural, though unfortunate?”
+</p>
+
+<p>
+It was a terrible idea he was framing, and he dwelt on it so that we might
+accept it at its full value. “As one doctor has said,” he added, “although
+toxicologists and chemists have not always possessed infallible tests for
+practical use, it is at present a pretty certain observation that every poison
+leaves its mark. But then on the other hand, students of criminology have said
+that a skilled physician or surgeon is about the only person now capable of
+carrying out a really scientific murder.
+</p>
+
+<p>
+“Which is true? It seems to me, at least in the latter case, that the very
+nicety of the handiwork must often serve as a clue in itself. The trained hand
+leaves the peculiar mark characteristic of its training. No matter how shrewdly
+the deed is planned, the execution of it is daily becoming a more and more
+difficult feat, thanks to our increasing knowledge of microbiology and
+pathology.”
+</p>
+
+<p>
+He had risen, as he finished the sentence, every eye fixed on him, as if he had
+been a master hypnotist.
+</p>
+
+<p>
+“Perhaps,” he said, taking off the cylinder from the phonograph and placing on
+one which I knew was that which had lain in the library closet over night,
+“perhaps some of the things I have said will explain or be explained by the
+record on this cylinder.”
+</p>
+
+<p>
+He had started the machine. So magical was the effect on the little audience
+that I am tempted to repeat what I had already heard, but had not myself yet
+been able to explain:
+</p>
+
+<p class="p2">
+“How is she to-day?”
+</p>
+
+<p>
+“Not much changed—perhaps not so well.”
+</p>
+
+<p>
+“It’s all right, though. That is natural. It is working well. I think you might
+increase the dose one tablet.”
+</p>
+
+<p>
+“You’re sure it is all right?”
+</p>
+
+<p>
+“Oh, positively—it has been done in Europe.”
+</p>
+
+<p>
+“I hope so. It must be a boy—and an <i>Atherton</i>.”
+</p>
+
+<p>
+“Never fear.”
+</p>
+
+<p>
+No one moved a muscle. If there was anyone in the room guilty of playing on the
+feelings and the health of an unfortunate woman, that person must have had
+superb control of his own feelings.
+</p>
+
+<p>
+“As you know,” resumed Kennedy thoughtfully, “there are and have been many
+theories of sex control. One of the latest, but by no means the only one, is
+that it can be done by use of the extracts of various glands administered to
+the mother. I do not know with what scientific authority it was stated, but I
+do know that some one has recently said that adrenalin, derived from the
+suprarenal glands, induces boys to develop—cholin, from the bile of the liver,
+girls. It makes no difference—in this case. There may have been a show of
+science. But it was to cover up a crime. Some one has been administering to
+Eugenia Atherton tablets of thyroid extract—ostensibly to aid her in fulfilling
+the dearest ambition of her soul—to become the mother of a new line of
+Athertons which might bear the same relation to the future of the country as
+the great family of the Edwards mothered by Elizabeth Tuttle.”
+</p>
+
+<p>
+He was bending over the two phonograph cylinders now, rapidly comparing the new
+one which he had made and that which he had just allowed to reel off its
+astounding revelation.
+</p>
+
+<p>
+“When a voice speaks into a phonograph,” he said, half to himself, “its
+modulations received on the diaphragm are written by a needle point upon the
+surface of a cylinder or disk in a series of fine waving or zigzag lines of
+infinitely varying depth or breadth. Dr. Marage and others have been able to
+distinguish vocal sounds by the naked eye on phonograph records. Mr. Edison has
+studied them with the microscope in his world-wide search for the perfect
+voice.
+</p>
+
+<p>
+“In fact, now it is possible to identify voices by the records they make, to
+get at the precise meaning of each slightest variation of the lines with
+mathematical accuracy. They can no more be falsified than handwriting can be
+forged so that modern science cannot detect it or than typewriting can be
+concealed and attributed to another machine. The voice is like a finger print,
+a portrait parlé—unescapable.”
+</p>
+
+<p>
+He glanced up, then back again. “This microscope shows me,” he said, “that the
+voices on that cylinder you heard are identical with two on this record which I
+have just made in this room.”
+</p>
+
+<p>
+“Walter,” he said, motioning to me, “look.”
+</p>
+
+<p>
+I glanced into the eyepiece and saw a series of lines and curves, peculiar
+waves lapping together and making an appearance in some spots almost like tooth
+marks. Although I did not understand the details of the thing, I could readily
+see that by study one might learn as much about it as about loops, whorls, and
+arches on finger tips.
+</p>
+
+<p>
+“The upper and lower lines,” he explained, “with long regular waves, on that
+highly magnified section of the record, are formed by the voice with no
+overtones. The three lines in the middle, with rhythmic ripples, show the
+overtones.”
+</p>
+
+<p>
+He paused a moment and faced us. “Many a person,” he resumed, “is a biotype in
+whom a full complement of what are called inhibitions never develops. That is
+part of your eugenics. Throughout life, and in spite of the best of training,
+that person reacts now and then to a certain stimulus directly. A man stands
+high; once a year he falls with a lethal quantity of alcohol. A woman,
+brilliant, accomplished, slips away and spends a day with a lover as unlike
+herself as can be imagined.
+</p>
+
+<p>
+“The voice that interests me most on these records,” he went on, emphasizing
+the words with one of the cylinders which he still held, “is that of a person
+who has been working on the family pride of another. That person has persuaded
+the other to administer to Eugenia an extract because ‘it must be a boy and an
+Atherton.’ That person is a high-class defective, born with a criminal
+instinct, reacting to it in an artful way. Thank God, the love of a man whom
+theoretical eugenics condemned, roused us in—”
+</p>
+
+<p>
+A cry at the door brought us all to our feet, with hearts thumping as if they
+were bursting.
+</p>
+
+<p>
+It was Eugenia Atherton, wild-eyed, erect, staring.
+</p>
+
+<p>
+I stood aghast at the vision. Was she really to be the Lady Madeline in this
+fall of the House of Atherton?
+</p>
+
+<p>
+“Edith—I—I missed you. I heard voices. Is—is it true—what this man—says? Is
+my—my baby—”
+</p>
+
+<p>
+Quincy Atherton leaped forward and caught her as she reeled. Quickly Craig
+threw open a window for air, and as he did so leaned far out and blew shrilly
+on a police whistle.
+</p>
+
+<p>
+The young man looked up from Eugenia, over whom he was bending, scarcely
+heeding what else went on about him. Still, there was no trace of anger on his
+face, in spite of the great wrong that had been done him. There was room for
+only one great emotion—only anxiety for the poor girl who had suffered so
+cruelly merely for taking his name.
+</p>
+
+<p>
+Kennedy saw the unspoken question in his eyes.
+</p>
+
+<p>
+“Eugenia is a pure normal, as Dr. Crafts told you,” he said gently. “A few
+weeks, perhaps only days, of treatment—the thyroid will revert to its normal
+state—and Eugenia Gilman will be the mother of a new house of Atherton which
+may eclipse even the proud record of the founder of the old.”
+</p>
+
+<p>
+“Who blew the whistle?” demanded a gruff voice at the door, as a tall bluecoat
+puffed past the scandalized butler.
+</p>
+
+<p>
+“Arrest that woman,” pointed Kennedy. “She is the poisoner. Either as wife of
+Burroughs, whom she fascinates and controls as she does Edith, she planned to
+break the will of Quincy or, in the other event, to administer the fortune as
+head of the Eugenics Foundation after the death of Dr. Crafts, who would have
+followed Eugenia and Quincy Atherton.”
+</p>
+
+<p>
+I followed the direction of Kennedy’s accusing finger. Maude Schofield’s face
+betrayed more than even her tongue could have confessed.

+THE BILLIONAIRE BABY</h2>
+
+<p>
+Coming to us directly as a result of the talk that the Atherton case provoked
+was another that involved the happiness of a wealthy family to a no less
+degree.
+</p>
+
+<p>
+“I suppose you have heard of the ‘billionaire baby,’ Morton Hazleton III?”
+asked Kennedy of me one afternoon shortly afterward.
+</p>
+
+<p>
+The mere mention of the name conjured up in my mind a picture of the lusty
+two-year-old heir of two fortunes, as the feature articles in the <i>Star</i>
+had described that little scion of wealth—his luxurious nursery, his
+magnificent toys, his own motor car, a trained nurse and a detective on guard
+every hour of the day and night, every possible precaution for his health and
+safety.
+</p>
+
+<p>
+“Gad, what a lucky kid!” I exclaimed involuntarily.
+</p>
+
+<p>
+“Oh, I don’t know about that,” put in Kennedy. “The fortune may be exaggerated.
+His happiness is, I’m sure.”
+</p>
+
+<p>
+He had pulled from his pocketbook a card and handed it to me. It read: “Gilbert
+Butler, American representative, Lloyd’s.”
+</p>
+
+<p>
+“Lloyd’s?” I queried. “What has Lloyd’s to do with the billion-dollar baby?”
+</p>
+
+<p>
+“Very much. The child has been insured with them for some fabulous sum against
+accident, including kidnaping.”
+</p>
+
+<p>
+“Yes?” I prompted, “sensing” a story.
+</p>
+
+<p>
+“Well, there seem to have been threats of some kind, I understand. Mr. Butler
+has called on me once already to-day to retain my services and is going
+to—ah—there he is again now.”
+</p>
+
+<p>
+Kennedy had answered the door buzzer himself, and Mr. Butler, a tall,
+sloping-shouldered Englishman, entered.
+</p>
+
+<p>
+“Has anything new developed?” asked Kennedy, introducing me.
+</p>
+
+<p>
+“I can’t say,” replied Butler dubiously. “I rather think we have found
+something that may have a bearing on the case. You know Miss Haversham,
+Veronica Haversham?”
+</p>
+
+<p>
+“The actress and professional beauty? Yes—at least I have seen her. Why?”
+</p>
+
+<p>
+“We hear that Morton Hazleton knows her, anyhow,” remarked Butler dryly.
+</p>
+
+<p>
+“Well?”
+</p>
+
+<p>
+“Then you don’t know the gossip?” he cut in. “She is said to be in a sanitarium
+near the city. I’ll have to find that out for you. It’s a fast set she has been
+traveling with lately, including not only Hazleton, but Dr. Maudsley, the
+Hazleton physician, and one or two others, who if they were poorer might be
+called desperate characters.”
+</p>
+
+<p>
+“Does Mrs. Hazleton know of—of his reputed intimacy?”
+</p>
+
+<p>
+“I can’t say that, either. I presume that she is no fool.”
+</p>
+
+<p>
+Morton Hazleton, Jr., I knew, belonged to a rather smart group of young men. He
+had been mentioned in several near-scandals, but as far as I knew there had
+been nothing quite as public and definite as this one.
+</p>
+
+<p>
+“Wouldn’t that account for her fears?” I asked.
+</p>
+
+<p>
+“Hardly,” replied Butler, shaking his head. “You see, Mrs. Hazleton is a
+nervous wreck, but it’s about the baby, and caused, she says, by her fears for
+its safety. It came to us only in a roundabout way, through a servant in the
+house who keeps us in touch. The curious feature is that we can seem to get
+nothing definite from her about her fears. They may be groundless.”
+</p>
+
+<p>
+Butler shrugged his shoulders and proceeded, “And they may be well-founded. But
+we prefer to run no chances in a case of this kind. The child, you know, is
+guarded in the house. In his perambulator he is doubly guarded, and when he
+goes out for his airing in the automobile, two men, the chauffeur and a
+detective, are always there, besides his nurse, and often his mother or
+grandmother. Even in the nursery suite they have iron shutters which can be
+pulled down and padlocked at night and are constructed so as to give plenty of
+fresh air even to a scientific baby. Master Hazleton was the best sort of risk,
+we thought. But now—we don’t know.”
+</p>
+
+<p>
+“You can protect yourselves, though,” suggested Kennedy.
+</p>
+
+<p>
+“Yes, we have, under the policy, the right to take certain measures to protect
+ourselves in addition to the precautions taken by the Hazletons. We have added
+our own detective to those already on duty. But we—we don’t know what to guard
+against,” he concluded, perplexed. “We’d like to know—that’s all. It’s too big
+a risk.”
+</p>
+
+<p>
+“I may see Mrs. Hazleton?” mused Kennedy.
+</p>
+
+<p>
+“Yes. Under the circumstances she can scarcely refuse to see anyone we send.
+I’ve arranged already for you to meet her within an hour. Is that all right?”
+</p>
+
+<p>
+“Certainly.”
+</p>
+
+<p>
+The Hazleton home in winter in the city was uptown, facing the river. The large
+grounds adjoining made the Hazletons quite independent of the daily infant
+parade which one sees along Riverside Drive.
+</p>
+
+<p>
+As we entered the grounds we could almost feel the very atmosphere on guard. We
+did not see the little subject of so much concern, but I remembered his much
+heralded advent, when his grandparents had settled a cold million on him, just
+as a reward for coming into the world. Evidently, Morton, Sr., had hoped that
+Morton, Jr., would calm down, now that there was a third generation to
+consider. It seemed that he had not. I wondered if that had really been the
+occasion of the threats or whatever it was that had caused Mrs. Hazleton’s
+fears, and whether Veronica Haversham or any of the fast set around her had had
+anything to do with it.
+</p>
+
+<p>
+Millicent Hazleton was a very pretty little woman, in whom one saw
+instinctively the artistic temperament. She had been an actress, too, when
+young Morton Hazleton married her, and at first, at least, they had seemed very
+devoted to each other.
+</p>
+
+<p>
+We were admitted to see her in her own library, a tastefully furnished room on
+the second floor of the house, facing a garden at the side.
+</p>
+
+<p>
+“Mrs. Hazleton,” began Butler, smoothing the way for us, “of course you realize
+that we are working in your interests. Professor Kennedy, therefore, in a
+sense, represents both of us.”
+</p>
+
+<p>
+“I am quite sure I shall be delighted to help you,” she said with an absent
+expression, though not ungraciously.
+</p>
+
+<p>
+Butler, having introduced us, courteously withdrew. “I leave this entirely in
+your hands,” he said, as he excused himself. “If you want me to do anything
+more, call on me.”
+</p>
+
+<p>
+I must say that I was much surprised at the way she had received us. Was there
+in it, I wondered, an element of fear lest if she refused to talk suspicion
+might grow even greater? One could see anxiety plainly enough on her face, as
+she waited for Kennedy to begin.
+</p>
+
+<p>
+A few moments of general conversation then followed.
+</p>
+
+<p>
+“Just what is it you fear?” he asked, after having gradually led around to the
+subject. “Have there been any threatening letters?”
+</p>
+
+<p>
+“N-no,” she hesitated, “at least nothing—definite.”
+</p>
+
+<p>
+“Gossip?” he hinted.
+</p>
+
+<p>
+“No.” She said it so positively that I fancied it might be taken for a plain
+“Yes.”
+</p>
+
+<p>
+“Then what is it?” he asked, very deferentially, but firmly.
+</p>
+
+<p>
+She had been looking out at the garden. “You couldn’t understand,” she
+remarked. “No detective—” she stopped.
+</p>
+
+<p>
+“You may be sure, Mrs. Hazleton, that I have not come here unnecessarily to
+intrude,” he reassured her. “It is exactly as Mr. Butler put it. We—want to
+help you.”
+</p>
+
+<p>
+I fancied there seemed to be something compelling about his manner. It was at
+once sympathetic and persuasive. Quite evidently he was taking pains to break
+down the prejudice in her mind which she had already shown toward the ordinary
+detective.
+</p>
+
+<p>
+“You would think me crazy,” she remarked slowly. “But it is just a—a dream—just
+dreams.”
+</p>
+
+<p>
+I don’t think she had intended to say anything, for she stopped short and
+looked at him quickly as if to make sure whether he could understand. As for
+myself, I must say I felt a little skeptical. To my surprise, Kennedy seemed to
+take the statement at its face value.
+</p>
+
+<p>
+“Ah,” he remarked, “an anxiety dream? You will pardon me, Mrs. Hazleton, but
+before we go further let me tell you frankly that I am much more than an
+ordinary detective. If you will permit me, I should rather have you think of me
+as a psychologist, a specialist, one who has come to set your mind at rest
+rather than to worm things from you by devious methods against which you have
+to be on guard. It is just for such an unusual case as yours that Mr. Butler
+has called me in. By the way, as our interview may last a few minutes, would
+you mind sitting down? I think you’ll find it easier to talk if you can get
+your mind perfectly at rest, and for the moment trust to the nurse and the
+detectives who are guarding the garden, I am sure, perfectly.”
+</p>
+
+<p>
+She had been standing by the window during the interview and was quite
+evidently growing more and more nervous. With a bow Kennedy placed her at her
+ease on a chaise lounge.
+</p>
+
+<p>
+“Now,” he continued, standing near her, but out of sight, “you must try to
+remain free from all external influences and impressions. Don’t move. Avoid
+every use of a muscle. Don’t let anything distract you. Just concentrate your
+attention on your psychic activities. Don’t suppress one idea as unimportant,
+irrelevant, or nonsensical. Simply tell me what occurs to you in connection
+with the dreams—everything,” emphasized Craig.
+</p>
+
+<p>
+I could not help feeling surprised to find that she accepted Kennedy’s
+deferential commands, for after all that was what they amounted to. Almost I
+felt that she was turning to him for help, that he had broken down some barrier
+to her confidence. He seemed to exert a sort of hypnotic influence over her.
+</p>
+
+<p>
+“I have had cases before which involved dreams,” he was saying quietly and
+reassuringly. “Believe me, I do not share the world’s opinion that dreams are
+nothing. Nor yet do I believe in them superstitiously. I can readily understand
+how a dream can play a mighty part in shaping the feelings of a high-tensioned
+woman. Might I ask exactly what it is you fear in your dreams?”
+</p>
+
+<p>
+She sank her head back in the cushions, and for a moment closed her eyes, half
+in weariness, half in tacit obedience to him. “Oh, I have such horrible
+dreams,” she said at length, “full of anxiety and fear for Morton and little
+Morton. I can’t explain it. But they are so horrible.”
+</p>
+
+<p>
+Kennedy said nothing. She was talking freely at last.
+</p>
+
+<p>
+“Only last night,” she went on, “I dreamt that Morton was dead. I could see the
+funeral, all the preparations, and the procession. It seemed that in the crowd
+there was a woman. I could not see her face, but she had fallen down and the
+crowd was around her. Then Dr. Maudsley appeared. Then all of a sudden the
+dream changed. I thought I was on the sand, at the seashore, or perhaps a lake.
+I was with Junior and it seemed as if he were wading in the water, his head
+bobbing up and down in the waves. It was like a desert, too—the sand. I turned,
+and there was a lion behind me. I did not seem to be afraid of him, although I
+was so close that I could almost feel his shaggy mane. Yet I feared that he
+might bite Junior. The next I knew I was running with the child in my arms. I
+escaped—and—oh, the relief!”
+</p>
+
+<p>
+She sank back, half exhausted, half terrified still by the recollection.
+</p>
+
+<p>
+“In your dream when Dr. Maudsley appeared,” asked Kennedy, evidently interested
+in filling in the gap, “what did he do?”
+</p>
+
+<p>
+“Do?” she repeated. “In the dream? Nothing.”
+</p>
+
+<p>
+“Are you sure?” he asked, shooting a quick glance at her.
+</p>
+
+<p>
+“Yes. That part of the dream became indistinct. I’m sure he did nothing, except
+shoulder through the crowd. I think he had just entered. Then that part of the
+dream seemed to end and the second part began.”
+</p>
+
+<p>
+Piece by piece Kennedy went over it, putting it together as if it were a
+mosaic.
+</p>
+
+<p>
+“Now, the woman. You say her face was hidden?”
+</p>
+
+<p>
+She hesitated. “N—no. I saw it. But it was no one I knew.”
+</p>
+
+<p>
+Kennedy did not dwell on the contradiction, but added, “And the crowd?”
+</p>
+
+<p>
+“Strangers, too.”
+</p>
+
+<p>
+“Dr. Maudsley is your family physician?” he questioned.
+</p>
+
+<p>
+“Yes.”
+</p>
+
+<p>
+“Did he call—er—yesterday?”
+</p>
+
+<p>
+“He calls every day to supervise the nurse who has Junior in charge.”
+</p>
+
+<p>
+“Could one always be true to oneself in the face of any temptation?” he asked
+suddenly.
+</p>
+
+<p>
+It was a bold question. Yet such had been the gradual manner of his leading up
+to it that, before she knew it, she had answered quite frankly, “Yes—if one
+always thought of home and her child, I cannot see how one could help
+controlling herself.”
+</p>
+
+<p>
+She seemed to catch her breath, almost as though the words had escaped her
+before she knew it.
+</p>
+
+<p>
+“Is there anything besides your dream that alarms you,” he asked, changing the
+subject quickly, “any suspicion of—say the servants?”
+</p>
+
+<p>
+“No,” she said, watching him now. “But some time ago we caught a burglar
+upstairs here. He managed to escape. That has made me nervous. I didn’t think
+it was possible.”
+</p>
+
+<p>
+“Anything else?”
+</p>
+
+<p>
+“No,” she said positively, this time on her guard.
+</p>
+
+<p>
+Kennedy saw that she had made up her mind to say no more.
+</p>
+
+<p>
+“Mrs. Hazleton,” he said, rising. “I can hardly thank you too much for the
+manner in which you have met my questions. It will make it much easier for me
+to quiet your fears. And if anything else occurs to you, you may rest assured I
+shall violate no confidences in your telling me.”
+</p>
+
+<p>
+I could not help the feeling, however, that there was just a little air of
+relief on her face as we left.

+<h2><a name="chap35"></a>CHAPTER XXXV<br/>
+THE PSYCHANALYSIS</h2>
+
+<p>
+“H-m,” mused Kennedy as we walked along after leaving the house. “There were
+several ‘complexes,’ as they are called, there—the most interesting and
+important being the erotic, as usual. Now, take the lion in the dream, with his
+mane. That, I suspect, was Dr. Maudsley. If you are acquainted with him, you
+will recall his heavy, almost tawny beard.”
+</p>
+
+<p>
+Kennedy seemed to be revolving something in his mind and I did not interrupt. I
+had known him too long to feel that even a dream might not have its value with
+him. Indeed, several times before he had given me glimpses into the fascinating
+possibilities of the new psychology.
+</p>
+
+<p>
+“In spite of the work of thousands of years, little progress has been made in
+the scientific understanding of dreams,” he remarked a few moments later.
+“Freud, of Vienna—you recall the name?—has done most, I think in that
+direction.”
+</p>
+
+<p>
+I recalled something of the theories of the Freudists, but said nothing.
+</p>
+
+<p>
+“It is an unpleasant feature of his philosophy,” he went on, “but Freud finds
+the conclusion irresistible that all humanity underneath the shell is sensuous
+and sensual in nature. Practically all dreams betray some delight of the senses
+and sexual dreams are a large proportion. There is, according to the theory,
+always a wish hidden or expressed in a dream. The dream is one of three things,
+the open, the disguised or the distorted fulfillment of a wish, sometimes
+recognized, sometimes repressed.
+</p>
+
+<p>
+“Anxiety dreams are among the most interesting and important Anxiety may
+originate in psycho-sexual excitement, the repressed libido, as the Freudists
+call it. Neurotic fear has its origin in sexual life and corresponds to a
+libido which has been turned away from its object and has not succeeded in
+being applied. All so-called day dreams of women are erotic; of men they are
+either ambition or love.
+</p>
+
+<p>
+“Often dreams, apparently harmless, turn out to be sinister if we take pains to
+interpret them. All have the mark of the beast. For example, there was that
+unknown woman who had fallen down and was surrounded by a crowd. If a woman
+dreams that, it is sexual. It can mean only a fallen woman. That is the
+symbolism. The crowd always denotes a secret.
+</p>
+
+<p>
+“Take also the dream of death. If there is no sorrow felt, then there is
+another cause for it. But if there is sorrow, then the dreamer really desires
+death or absence. I expect to have you quarrel with that. But read Freud, and
+remember that in childhood death is synonymous with being away. Thus for
+example, if a girl dreams that her mother is dead, perhaps it means only that
+she wishes her away so that she can enjoy some pleasure that her strict parent,
+by her presence, denies.
+</p>
+
+<p>
+“Then there was that dream about the baby in the water. That, I think, was a
+dream of birth. You see, I asked her practically to repeat the dreams because
+there were several gaps. At such points one usually finds first hesitation,
+then something that shows one of the main complexes. Perhaps the subject grows
+angry at the discovery.
+</p>
+
+<p>
+“Now, from the tangle of the dream thought, I find that she fears that her
+husband is too intimate with another woman, and that perhaps unconsciously she
+has turned to Dr. Maudsley for sympathy. Dr. Maudsley, as I said, is not only
+bearded, but somewhat of a social lion. He had called on her the day before. Of
+such stuff are all dream lions when there is no fear. But she shows that she
+has been guilty of no wrongdoing—she escaped, and felt relieved.”
+</p>
+
+<p>
+“I’m glad of that,” I put in. “I don’t like these scandals. On the <i>Star</i>
+when I have to report them, I do it always under protest. I don’t know what
+your psychanalysis is going to show in the end, but I for one have the greatest
+sympathy for that poor little woman in the big house alone, surrounded by and
+dependent on servants, while her husband is out collecting scandals.”
+</p>
+
+<p>
+“Which suggests our next step,” he said, turning the subject. “I hope that
+Butler has found out the retreat of Veronica Haversham.”
+</p>
+
+<p>
+We discovered Miss Haversham at last at Dr. Klemm’s sanitarium, up in the hills
+of Westchester County, a delightful place with a reputation for its rest cures.
+Dr. Klemm was an old friend of Kennedy’s, having had some connection with the
+medical school at the University.
+</p>
+
+<p>
+She had gone up there rather suddenly, it seemed, to recuperate. At least that
+was what was given out, though there seemed to be much mystery about her, and
+she was taking no treatment as far as was known.
+</p>
+
+<p>
+“Who is her physician?” asked Kennedy of Dr. Klemm as we sat in his luxurious
+office.
+</p>
+
+<p>
+“A Dr. Maudsley of the city.”
+</p>
+
+<p>
+Kennedy glanced quickly at me in time to check an exclamation.
+</p>
+
+<p>
+“I wonder if I could see her?”
+</p>
+
+<p>
+“Why, of course—if she is willing,” replied Dr. Klemm.
+</p>
+
+<p>
+“I will have to have some excuse,” ruminated Kennedy. “Tell her I am a
+specialist in nervous troubles from the city, have been visiting one of the
+other patients, anything.”
+</p>
+
+<p>
+Dr. Klemm pulled down a switch on a large oblong oak box on his desk, asked for
+Miss Haversham, and waited a moment.
+</p>
+
+<p>
+“What is that?” I asked.
+</p>
+
+<p>
+“A vocaphone,” replied Kennedy. “This sanitarium is quite up to date, Klemm.”
+</p>
+
+<p>
+The doctor nodded and smiled. “Yes, Kennedy,” he replied. “Communicating with
+every suite of rooms we have the vocaphone. I find it very convenient to have
+these microphones, as I suppose you would call them, catching your words
+without talking into them directly as you have to do in the telephone and then
+at the other end emitting the words without the use of an earpiece, from the
+box itself, as if from a megaphone horn. Miss Haversham, this is Dr. Klemm.
+There is a Dr. Kennedy here visiting another patient, a specialist from New
+York. He’d like very much to see you if you can spare a few minutes.”
+</p>
+
+<p>
+“Tell him to come up.” The voice seemed to come from the vocaphone as though
+she were in the room with us.
+</p>
+
+<p>
+Veronica Haversham was indeed wonderful, one of the leading figures in the
+night life of New York, a statuesque brunette of striking beauty, though I had
+heard of often ungovernable temper. Yet there was something strange about her
+face here. It seemed perhaps a little yellow, and I am sure that her nose had a
+peculiar look as if she were suffering from an incipient rhinitis. The pupils
+of her eyes were as fine as pin heads, her eyebrows were slightly elevated.
+Indeed, I felt that she had made no mistake in taking a rest if she would
+preserve the beauty which had made her popularity so meteoric.
+</p>
+
+<p>
+“Miss Haversham,” began Kennedy, “they tell me that you are suffering from
+nervousness. Perhaps I can help you. At any rate it will do no harm to try. I
+know Dr. Maudsley well, and if he doesn’t approve—well, you may throw the
+treatment into the waste basket.”
+</p>
+
+<p>
+“I’m sure I have no reason to refuse,” she said. “What would you suggest?”
+</p>
+
+<p>
+“Well, first of all, there is a very simple test I’d like to try. You won’t
+find that it bothers you in the least—and if I can’t help you, then no harm is
+done.”
+</p>
+
+<p>
+Again I watched Kennedy as he tactfully went through the preparations for
+another kind of psychanalysis, placing Miss Haversham at her ease on a
+davenport in such a way that nothing would distract her attention. As she
+reclined against the leather pillows in the shadow it was not difficult to
+understand the lure by which she held together the little coterie of her
+intimates. One beautiful white arm, bare to the elbow, hung carelessly over the
+edge of the davenport, displaying a plain gold bracelet.
+</p>
+
+<p>
+“Now,” began Kennedy, on whom I knew the charms of Miss Haversham produced a
+negative effect, although one would never have guessed it from his manner, “as
+I read off from this list of words, I wish that you would repeat the first
+thing, anything,” he emphasized, “that comes into your head, no matter how
+trivial it may seem. Don’t force yourself to think. Let your ideas flow
+naturally. It depends altogether on your paying attention to the words and
+answering as quickly as you can—remember, the first word that comes into your
+mind. It is easy to do. We’ll call it a game,” he reassured.
+</p>
+
+<p>
+Kennedy handed a copy of the list to me to record the answers. There must have
+been some fifty words, apparently senseless, chosen at random, it seemed. They
+were:

+<p>
+“The Jung association word test is part of the Freud psychanalysis, also,” he
+whispered to me, “You remember we tried something based on the same idea once
+before?”
+</p>
+
+<p>
+I nodded. I had heard of the thing in connection with blood-pressure tests, but
+not this way.
+</p>
+
+<p>
+Kennedy called out the first word, “Head,” while in his hand he held a stop
+watch which registered to one-fifth of a second.
+</p>
+
+<p>
+Quickly she replied, “Ache,” with an involuntary movement of her hand toward
+her beautiful forehead.
+</p>
+
+<p>
+“Good,” exclaimed Kennedy. “You seem to grasp the idea better than most of my
+patients.”
+</p>
+
+<p>
+I had recorded the answer, he the time, and we found out, I recall afterward,
+that the time averaged something like two and two-fifths seconds.
+</p>
+
+<p>
+I thought her reply to the second word, “green,” was curious. It came quickly,
+“Envy.”
+</p>
+
+<p>
+However, I shall not attempt to give all the replies, but merely some of the
+most significant. There did not seem to be any hesitation about most of the
+words, but whenever Kennedy tried to question her about a word that seemed to
+him interesting she made either evasive or hesitating answers, until it became
+evident that in the back of her head was some idea which she was repressing and
+concealing from us, something that she set off with a mental “No Thoroughfare.”
+</p>
+
+<p>
+He had finished going through the list, and Kennedy was now studying over the
+answers and comparing the time records.
+</p>
+
+<p>
+“Now,” he said at length, running his eye over the words again, “I want to
+repeat the performance. Try to remember and duplicate your first replies,” he
+said.
+</p>
+
+<p>
+Again we went through what at first had seemed to me to be a solemn farce, but
+which I began to see was quite important. Sometimes she would repeat the answer
+exactly as before. At other times a new word would occur to her. Kennedy was
+keen to note all the differences in the two lists.
+</p>
+
+<p>
+One which I recall because the incident made an impression on me had to do with
+the trio, “Death—life—inevitable.”
+</p>
+
+<p>
+“Why that?” he asked casually.
+</p>
+
+<p>
+“Haven’t you ever heard the saying, ‘One should let nothing which one can have
+escape, even if a little wrong is done; no opportunity should be missed; life
+is so short, death inevitable’?”
+</p>
+
+<p>
+There were several others which to Kennedy seemed more important, but long
+after we had finished I pondered this answer. Was that her philosophy of life?
+Undoubtedly she would never have remembered the phrase if it had not been so,
+at least in a measure.
+</p>
+
+<p>
+She had begun to show signs of weariness, and Kennedy quickly brought the
+conversation around to subjects of apparently a general nature, but skillfully
+contrived so as to lead the way along lines her answers had indicated.
+</p>
+
+<p>
+Kennedy had risen to go, still chatting. Almost unintentionally he picked up
+from a dressing table a bottle of white tablets, without a label, shaking it to
+emphasize an entirely, and I believe purposely, irrelevant remark.
+</p>
+
+<p>
+“By the way,” he said, breaking off naturally, “what is that?”
+</p>
+
+<p>
+“Only something Dr. Maudsley had prescribed for me,” she answered quickly.
+</p>
+
+<p>
+As he replaced the bottle and went on with the thread of the conversation, I
+saw that in shaking the bottle he had abstracted a couple of the tablets before
+she realized it. “I can’t tell you just what to do without thinking the case
+over,” he concluded, rising to go. “Yours is a peculiar case, Miss Haversham,
+baffling. I’ll have to study it over, perhaps ask Dr. Maudsley If I may see you
+again. Meanwhile, I am sure what he is doing is the correct thing.”
+</p>
+
+<p>
+Inasmuch as she had said nothing about what Dr. Maudsley was doing, I wondered
+whether there was not just a trace of suspicion in her glance at him from under
+her long dark lashes.
+</p>
+
+<p>
+“I can’t see that you have done anything,” she remarked pointedly. “But then
+doctors are queer—queer.”
+</p>
+
+<p>
+That parting shot also had in it, for me, something to ponder over. In fact I
+began to wonder if she might not be a great deal more clever than even Kennedy
+gave her credit for being, whether she might not have submitted to his tests
+for pure love of pulling the wool over his eyes.
+</p>
+
+<p>
+Downstairs again, Kennedy paused only long enough to speak a few words with his
+friend Dr. Klemm.
+</p>
+
+<p>
+“I suppose you have no idea what Dr. Maudsley has prescribed for her?” he asked
+carelessly.
+</p>
+
+<p>
+“Nothing, as far as I know, except rest and simple food.”
+</p>
+
+<p>
+He seemed to hesitate, then he said under his voice, “I suppose you know that
+she is a regular dope fiend, seasons her cigarettes with opium, and all that.”
+</p>
+
+<p>
+“I guessed as much,” remarked Kennedy, “but how does she get it here?”
+</p>
+
+<p>
+“She doesn’t.”
+</p>
+
+<p>
+“I see,” remarked Craig, apparently weighing now the man before him. At length
+he seemed to decide to risk something.
+</p>
+
+<p>
+“Klemm,” he said, “I wish you would do something for me. I see you have the
+vocaphone here. Now if—say Hazleton—should call—will you listen in on that
+vocaphone for me?” Dr. Klemm looked squarely at him.
+</p>
+
+<p>
+“Kennedy,” he said, “it’s unprofessional, but—-”
+</p>
+
+<p>
+“So it is to let her be doped up under guise of a cure.”
+</p>
+
+<p>
+“What?” he asked, startled. “She’s getting the stuff now?”
+</p>
+
+<p>
+“No, I didn’t say she was getting opium, or from anyone here. All the same, if
+you would just keep an ear open—-”
+</p>
+
+<p>
+“It’s unprofessional, but—you’d not ask it without a good reason. I’ll try.”
+</p>
+
+<p>
+It was very late when we got back to the city and we dined at an uptown
+restaurant which we had almost to ourselves.
+</p>
+
+<p>
+Kennedy had placed the little whitish tablets in a small paper packet for safe
+keeping. As we waited for our order he drew one from his pocket, and after
+looking at it a moment crushed it to a powder in the paper.
+</p>
+
+<p>
+“What is it?” I asked curiously. “Cocaine?”
+</p>
+
+<p>
+“No,” he said, shaking his head doubtfully.
+</p>
+
+<p>
+He had tried to dissolve a little of the powder in some water from the glass
+before him, but it would not dissolve.
+</p>
+
+<p>
+As he continued to look at it his eye fell on the cut-glass vinegar cruet
+before us. It was full of the white vinegar.
+</p>
+
+<p>
+“Really acetic acid,” he remarked, pouring out a little.
+</p>
+
+<p>
+The white powder dissolved.
+</p>
+
+<p>
+For several minutes he continued looking at the stuff.
+</p>
+
+<p>
+“That, I think,” he remarked finally, “is heroin.”
+</p>
+
+<p>
+“More ‘happy dust’?” I replied with added interest now, thinking of our
+previous case. “Is the habit so extensive?”
+</p>
+
+<p>
+“Yes,” he replied, “the habit is comparatively new, although in Paris, I
+believe, they call the drug fiends, ‘heroinomaniacs.’ It is, as I told you
+before, a derivative of morphine. Its scientific name is diacetyl-morphin. It
+is New York’s newest peril, one of the most dangerous drugs yet. Thousands are
+slaves to it, although its sale is supposedly restricted. It is rotting the
+heart out of the Tenderloin. Did you notice Veronica Haversham’s yellowish
+whiteness, her down-drawn mouth, elevated eyebrows, and contracted eyes? She
+may have taken it up to escape other drugs. Some people have—and have just got
+a new habit. It can be taken hypodermically, or in a tablet, or by powdering
+the tablet to a white crystalline powder and snuffing up the nose. That’s the
+way she takes it. It produces rhinitis of the nasal passages, which I see you
+observed, but did not understand. It has a more profound effect than morphine,
+and is ten times as powerful as codeine. And one of the worst features is that
+so many people start with it, thinking it is as harmless as it has been
+advertised. I wouldn’t be surprised if she used from seventy-five to a hundred
+one-twelfth grain tablets a day. Some of them do, you know.”
+</p>
+
+<p>
+“And Dr. Maudsley,” I asked quickly, “do you think it is through him or in
+spite of him?”
+</p>
+
+<p>
+“That’s what I’d like to know. About those words,” he continued, “what did you
+make of the list and the answers?”
+</p>
+
+<p>
+I had made nothing and said so, rather quickly.
+</p>
+
+<p>
+“Those,” he explained, “were words selected and arranged to strike almost all
+the common complexes in analyzing and diagnosing. You’d think any intelligent
+person could give a fluent answer to them, perhaps a misleading answer. But try
+it yourself, Walter. You’ll find you can’t. You may start all right, but not
+all the words will be reacted to in the same time or with the same smoothness
+and ease. Yet, like the expressions of a dream, they often seem senseless. But
+they have a meaning as soon as they are ‘psychanalyzed.’ All the mistakes in
+answering the second time, for example, have a reason, if we can only get at
+it. They are not arbitrary answers, but betray the inmost subconscious
+thoughts, those things marked, split off from consciousness and repressed into
+the unconscious. Associations, like dreams, never lie. You may try to conceal
+the emotions and unconscious actions, but you can’t.”
+</p>
+
+<p>
+I listened, fascinated by Kennedy’s explanation.
+</p>
+
+<p>
+“Anyone can see that that woman has something on her mind besides the heroin
+habit. It may be that she is trying to shake the habit off in order to do it;
+it may be that she seeks relief from her thoughts by refuge in the habit; and
+it may be that some one has purposely caused her to contract this new habit in
+the guise of throwing off an old. The only way by which to find out is to study
+the case.”
+</p>
+
+<p>
+He paused. He had me keenly on edge, but I knew that he was not yet in a
+position to answer his queries positively.
+</p>
+
+<p>
+“Now I found,” he went on, “that the religious complexes were extremely few; as
+I expected the erotic were many. If you will look over the three lists you will
+find something queer about every such word as, ‘child, ‘to marry,’ ‘bride,’ ‘to
+lie,’ ‘stork,’ and so on. We’re on the right track. That woman does know
+something about that child.”
+</p>
+
+<p>
+“My eye catches the words ‘to sin,’ ‘to fall,’ ‘pure,’ and others,” I remarked,
+glancing over the list.
+</p>
+
+<p>
+“Yes, there’s something there, too. I got the hint for the drug from her
+hesitation over ‘needle’ and ‘white.’ But the main complex has to do with words
+relating to that child and to love. In short, I think we are going to find it
+to be the reverse of the rule of the French, that it will be a case of
+‘cherchez l’homme.’”
+</p>
+
+<p>
+Early the next day Kennedy, after a night of studying over the case, journeyed
+up to the sanitarium again. We found Dr. Klemm eager to meet us.
+</p>
+
+<p>
+“What is it?” asked Kennedy, equally eager.
+</p>
+
+<p>
+“I overheard some surprising things over the vocaphone,” he hastened. “Hazleton
+called. Why, there must have been some wild orgies in that precious set of
+theirs, and, would you believe it, many of them seem to have been at what Dr.
+Maudsley calls his ‘stable studio,’ a den he has fixed up artistically over his
+garage on a side street.”
+</p>
+
+<p>
+“Indeed?”
+</p>
+
+<p>
+“I couldn’t get it all, but I did hear her repeating over and over to Hazleton,
+‘Aren’t you all mine? Aren’t you all mine?’ There must be some vague jealousy
+lurking in the heart of that ardent woman. I can’t figure it out.”
+</p>
+
+<p>
+“I’d like to see her again,” remarked Kennedy. “Will you ask her if I may?”
+</p>

+THE ENDS OF JUSTICE</h2>
+
+<p>
+A few minutes later we were in the sitting room of her suite. She received us
+rather ungraciously, I thought.
+</p>
+
+<p>
+“Do you feel any better?” asked Kennedy.
+</p>
+
+<p>
+“No,” she replied curtly. “Excuse me for a moment. I wish to see that maid of
+mine. Clarisse!”
+</p>
+
+<p>
+She had hardly left the room when Kennedy was on his feet. The bottle of white
+tablets, nearly empty, was still on the table. I saw him take some very fine
+white powder and dust it quickly over the bottle. It seemed to adhere, and from
+his pocket he quickly drew a piece of what seemed to be specially prepared
+paper, laid it over the bottle where the powder adhered, fitting it over the
+curves. He withdrew it quickly, for outside we heard her light step, returning.
+I am sure she either saw or suspected that Kennedy had been touching the bottle
+of tablets, for there was a look of startled fear on her face.
+</p>
+
+<p>
+“Then you do not feel like continuing the tests we abandoned last night?” asked
+Kennedy, apparently not noticing her look.
+</p>
+
+<p>
+“No, I do not,” she almost snapped. “You—you are detectives. Mrs. Hazleton has
+sent you.”
+</p>
+
+<p>
+“Indeed, Mrs. Hazleton has not sent us,” insisted Kennedy, never for an instant
+showing his surprise at her mention of the name.
+</p>
+
+<p>
+“You are. You can tell her, you can tell everybody. I’ll tell—I’ll tell myself.
+I won’t wait. That child is mine—mine—not hers. Now—go!”
+</p>
+
+<p>
+Veronica Haversham on the stage never towered in a fit of passion as she did
+now in real life, as her ungovernable feelings broke forth tempestuously on us.
+</p>
+
+<p>
+I was astounded, bewildered at the revelation, the possibilities in those
+simple words, “The child is mine.” For a moment I was stunned. Then as the full
+meaning dawned on me I wondered in a flood of consciousness whether it was
+true. Was it the product of her drug-disordered brain? Had her desperate love
+for Hazleton produced a hallucination?
+</p>
+
+<p>
+Kennedy, silent, saw that the case demanded quick action. I shall never forget
+the breathless ride down from the sanitarium to the Hazleton house on Riverside
+Drive.
+</p>
+
+<p>
+“Mrs. Hazleton,” he cried, as we hurried in, “you will pardon me for this
+unceremonious intrusion, but it is most important. May I trouble you to place
+your fingers on this paper—so?”
+</p>
+
+<p>
+He held out to her a piece of the prepared paper. She looked at him once, then
+saw from his face that he was not to be questioned. Almost tremulously she did
+as he said, saying not a word. I wondered whether she knew the story of
+Veronica, or whether so far only hints of it had been brought to her.
+</p>
+
+<p>
+“Thank you,” he said quickly. “Now, if I may see Morton?”
+</p>
+
+<p>
+It was the first time we had seen the baby about whom the rapidly thickening
+events were crowding. He was a perfect specimen of well-cared-for, scientific
+infant.
+</p>
+
+<p>
+Kennedy took the little chubby fingers playfully in his own. He seemed at once
+to win the child’s confidence, though he may have violated scientific rules.
+One by one he pressed the little fingers on the paper, until little Morton
+crowed with delight as one little piggy after another “went to market.” He had
+deserted thousands of dollars’ worth of toys just to play with the simple piece
+of paper Kennedy had brought with him. As I looked at him, I thought of what
+Kennedy had said at the start. Perhaps this innocent child was not to be envied
+after all. I could hardly restrain my excitement over the astounding situation
+which had suddenly developed.
+</p>
+
+<p>
+“That will do,” announced Kennedy finally, carelessly folding up the paper and
+slipping it into his pocket. “You must excuse me now.”
+</p>
+
+<p>
+“You see,” he explained on the way to the laboratory, “that powder adheres to
+fresh finger prints, taking all the gradations. Then the paper with its
+paraffine and glycerine coating takes off the powder.”
+</p>
+
+<p>
+In the laboratory he buried himself in work, with microscope compasses,
+calipers, while I fumed impotently at the window.
+</p>
+
+<p>
+“Walter,” he called suddenly, “get Dr. Maudsley on the telephone. Tell him to
+come immediately to the laboratory.”
+</p>
+
+<p>
+Meanwhile Kennedy was busy arranging what he had discovered in logical order
+and putting on it the finishing touches.
+</p>
+
+<p>
+As Dr. Maudsley entered Kennedy greeted him and began by plunging directly into
+the case in answer to his rather discourteous inquiry as to why he had been so
+hastily summoned.
+</p>
+
+<p>
+“Dr. Maudsley,” said Craig, “I have asked you to call alone because, while I am
+on the verge of discovering the truth in an important case affecting Morton
+Hazleton and his wife, I am frankly perplexed as to how to go ahead.”
+</p>
+
+<p>
+The doctor seemed to shake with excitement as Kennedy proceeded.
+</p>
+
+<p>
+“Dr. Maudsley,” Craig added, dropping his voice, “is Morton III the son of
+Millicent Hazleton or not? You were the physician in attendance on her at the
+birth. Is he?”
+</p>
+
+<p>
+Maudsley had been watching Kennedy furtively at first, but as he rapped out the
+words I thought the doctor’s eyes would pop out of his head. Perspiration in
+great beads collected on his face.
+</p>
+
+<p>
+“P—professor K—Kennedy,” he muttered, frantically rubbing his face and lower
+jaw as if to compose the agitation he could so ill conceal, “let me explain.”
+</p>
+
+<p>
+“Yes, yes—go on,” urged Kennedy.
+</p>
+
+<p>
+“Mrs. Hazleton’s baby was born—dead. I knew how much she and the rest of the
+family had longed for an heir, how much it meant. And I—substituted for the
+dead child a newborn baby from the maternity hospital. It—it belonged to
+Veronica Haversham—then a poor chorus girl. I did not intend that she should
+ever know it. I intended that she should think her baby was dead. But in some
+way she found out. Since then she has become a famous beauty, has numbered
+among her friends even Hazleton himself. For nearly two years I have tried to
+keep her from divulging the secret. From time to time hints of it have leaked
+out. I knew that if Hazleton with his infatuation of her were to learn—-”
+</p>
+
+<p>
+“And Mrs. Hazleton, has she been told?” interrupted Kennedy.
+</p>
+
+<p>
+“I have been trying to keep it from her as long as I can, but it has been
+difficult to keep Veronica from telling it. Hazleton himself was so wild over
+her. And she wanted her son as she—-”
+</p>
+
+<p>
+“Maudsley,” snapped out Kennedy, slapping down on the table the mass of prints
+and charts which he had hurriedly collected and was studying, “you lie! Morton
+is Millicent Hazleton’s son. The whole story is blackmail. I knew it when she
+told me of her dreams and I suspected first some such devilish scheme as yours.
+Now I know it scientifically.”
+</p>
+
+<p>
+He turned over the prints.
+</p>
+
+<p>
+“I suppose that study of these prints, Maudsley, will convey nothing to you. I
+know that it is usually stated that there are no two sets of finger prints in
+the world that are identical or that can be confused. Still, there are certain
+similarities of finger prints and other characteristics, and these similarities
+have recently been exhaustively studied by Bertilion, who has found that there
+are clear relationships sometimes between mother and child in these respects.
+If Solomon were alive, doctor, he would not now have to resort to the expedient
+to which he did when the two women disputed over the right to the living child.
+Modern science is now deciding by exact laboratory methods the same problem as
+he solved by his unique knowledge of feminine psychology.
+</p>
+
+<p>
+“I saw how this case was tending. Not a moment too soon, I said to myself, ‘The
+hand of the child will tell.’ By the very variations in unlike things, such as
+finger and palm prints, as tabulated and arranged by Bertillon after study in
+thousands of cases, by the very loops, whorls, arches and composites, I have
+proved my case.
+</p>
+
+<p>
+“The dominancy, not the identity, of heredity through the infinite varieties of
+finger markings is sometimes very striking. Unique patterns in a parent have
+been repeated with marvelous accuracy in the child. I knew that negative
+results might prove nothing in regard to parentage, a caution which it is
+important to observe. But I was prepared to meet even that.
+</p>
+
+<p>
+“I would have gone on into other studies, such as Tammasia’s, of heredity in
+the veining of the back of the hands; I would have measured the hands, compared
+the relative proportion of the parts; I would have studied them under the X-ray
+as they are being studied to-day; I would have tried the Reichert blood crystal
+test which is being perfected now so that it will tell heredity itself. There
+is no scientific stone I would have left unturned until I had delved at the
+truth of this riddle. Fortunately it was not necessary. Simple finger prints
+have told me enough. And best of all, it has been in time to frustrate that
+devilish scheme you and Veronica Haversham have been slowly unfolding.”
+</p>
+
+<p>
+Maudsley crumpled up, as it were, at Kennedy’s denunciation. He seemed to
+shrink toward the door.
+</p>
+
+<p>
+“Yes,” cried Kennedy, with extended forefinger, “you may go—for the present.
+Don’t try to run away. You’re watched from this moment on.”
+</p>
+
+<p>
+Maudsley had retreated precipitately.
+</p>
+
+<p>
+I looked at Kennedy inquiringly. What to do? It was indeed a delicate
+situation, requiring the utmost care to handle. If the story had been told to
+Hazleton, what might he not have already done? He must be found first of all if
+we were to meet the conspiracy of these two.
+</p>
+
+<p>
+Kennedy reached quickly for the telephone. “There is one stream of scandal that
+can be dammed at its source,” he remarked, calling a number. “Hello. Klemm’s
+Sanitarium? I’d like to speak with Miss Haversham. What—gone? Disappeared?
+Escaped?”
+</p>
+
+<p>
+He hung up the receiver and looked at me blankly. I was speechless.
+</p>
+
+<p>
+A thousand ideas flew through our minds at once. Had she perceived the import
+of our last visit and was she now on her way to complete her plotted slander of
+Millicent Hazleton, though it pulled down on herself in the end the whole
+structure?
+</p>
+
+<p>
+Hastily Kennedy called Hazleton’s home, Butler, and one after another of
+Hazleton’s favorite clubs. It was not until noon that Butler himself found him
+and came with him, under protest, to the laboratory.
+</p>
+
+<p>
+“What is it—what have you found?” cried Butler, his lean form a-quiver with
+suppressed excitement.
+</p>
+
+<p>
+Briefly, one fact after another, sparing Hazleton nothing, Kennedy poured forth
+the story, how by hint and innuendo Maudsley had been working on Millicent,
+undermining her, little knowing that he had attacked in her a very tower of
+strength, how Veronica, infatuated by him, had infatuated him, had led him on
+step by step.
+</p>
+
+<p>
+Pale and agitated, with nerves unstrung by the life he had been leading,
+Hazleton listened. And as Kennedy hammered one fact after another home, he
+clenched his fists until the nails dug into his very palms.
+</p>
+
+<p>
+“The scoundrels,” he ground out, as Kennedy finished by painting the picture of
+the brave little broken-hearted woman fighting off she knew not what, and the
+golden-haired, innocent baby stretching out his arms in glee at the very chance
+to prove that he was what he was. “The scoundrels—take me to Maudsley now. I
+must see Maudsley. Quick!”
+</p>
+
+<p>
+As we pulled up before the door of the reconstructed stable-studio, Kennedy
+jumped out. The door was unlocked. Up the broad flight of stairs, Hazleton went
+two at a time. We followed him closely.
+</p>
+
+<p>
+Lying on the divan in the room that had been the scene of so many orgies,
+locked in each other’s arms, were two figures—Veronica Haversham and Dr.
+Maudsley.
+</p>
+
+<p>
+She must have gone there directly after our visit to Dr. Klemm’s, must have
+been waiting for him when he returned with his story of the exposure to answer
+her fears of us as Mrs. Hazleton’s detectives. In a frenzy of intoxication she
+must have flung her arms blindly about him in a last wild embrace.
+</p>
+
+<p>
+Hazleton looked, aghast.
+</p>
+
+<p>
+He leaned over and took her arm. Before he could frame the name, “Veronica!” he
+had recoiled.
+</p>
+
+<p>
+The two were cold and rigid.
+</p>
+
+<p>
+“An overdose of heroin this time,” muttered Kennedy.
+</p>
+
+<p>
+My head was in a whirl.
+</p>
+
+<p>
+Hazleton stared blankly at the two figures abjectly lying before him, as the
+truth burned itself indelibly into his soul. He covered his face with his
+hands. And still he saw it all.
+</p>
+
+<p>
+Craig said nothing. He was content to let what he had shown work in the man’s
+mind.
+</p>
+
+<p>
+“For the sake of—that baby—would she—would she forgive?” asked Hazleton,
+turning desperately toward Kennedy.
+</p>
+
+<p>
+Deliberately Kennedy faced him, not as scientist and millionaire, but as man
+and man.
+</p>
+
+<p>
+“From my psychanalysis,” he said slowly, “I should say that it IS within your
+power, in time, to change those dreams.”
+</p>
+
+<p>
+Hazleton grasped Kennedy’s hand before he knew it.
+</p>
+

+1.A. By reading or using any part of this Project Gutenberg&#8482;
+electronic work, you indicate that you have read, understand, agree to
+and accept all the terms of this license and intellectual property
+(trademark/copyright) agreement. If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or
+destroy all copies of Project Gutenberg&#8482; electronic works in your
+possession. If you paid a fee for obtaining a copy of or access to a

+<div style='display:block; margin:1em 0'>
+1.B. &#8220;Project Gutenberg&#8221; is a registered trademark. It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement. There are a few
+things that you can do with most Project Gutenberg&#8482; electronic works
+even without complying with the full terms of this agreement. See
+paragraph 1.C below. There are a lot of things you can do with Project
+Gutenberg&#8482; electronic works if you follow the terms of this
+agreement and help preserve free future access to Project Gutenberg&#8482;
+electronic works. See paragraph 1.E below.
+</div>
+
+<div style='display:block; margin:1em 0'>
+1.C. The Project Gutenberg Literary Archive Foundation (&#8220;the
+Foundation&#8221; or PGLAF), owns a compilation copyright in the collection
+of Project Gutenberg&#8482; electronic works. Nearly all the individual
+works in the collection are in the public domain in the United
+States. If an individual work is unprotected by copyright law in the
+United States and you are located in the United States, we do not
+claim a right to prevent you from copying, distributing, performing,
+displaying or creating derivative works based on the work as long as
+all references to Project Gutenberg are removed. Of course, we hope
+that you will support the Project Gutenberg&#8482; mission of promoting
+free access to electronic works by freely sharing Project Gutenberg&#8482;
+works in compliance with the terms of this agreement for keeping the
+Project Gutenberg&#8482; name associated with the work. You can easily
+comply with the terms of this agreement by keeping this work in the
+same format with its attached full Project Gutenberg&#8482; License when
+you share it without charge with others.
+</div>
+
+<div style='display:block; margin:1em 0'>
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are
+in a constant state of change. If you are outside the United States,
+check the laws of your country in addition to the terms of this
+agreement before downloading, copying, displaying, performing,
+distributing or creating derivative works based on this work or any
+other Project Gutenberg&#8482; work. The Foundation makes no
+representations concerning the copyright status of any work in any
+country other than the United States.

+Project Gutenberg&#8482; is synonymous with the free distribution of

+Volunteers and financial support to provide volunteers with the

+goals and ensuring that the Project Gutenberg&#8482; collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure

+increasing the number of public domain and licensed works that can be

+The Foundation is committed to complying with the laws regulating

+INTRODUCTION
+
+
+As I look back now on the sensational events of the past months since
+the great European War began, it seems to me as if there had never been
+a period in Craig Kennedy's life more replete with thrilling adventures
+than this.
+
+In fact, scarcely had one mysterious event been straightened out from
+the tangled skein, when another, even more baffling, crowded on its
+very heels.
+
+As was to have been expected with us in America, not all of these
+remarkable experiences grew either directly or indirectly out of the
+war, but there were several that did, and they proved to be only the
+beginning of a succession of events which kept me busy chronicling for
+the Star the exploits of my capable and versatile friend.
+
+Altogether, this period of the war was, I am sure, quite the most
+exciting of the many series of episodes through which Craig has been
+called upon to go. Yet he seemed to meet each situation as it arose
+with a fresh mind, which was amazing even to me who have known him so
+long and so intimately.
+
+As was naturally to be supposed, also, at such a time, it was not long
+before Craig found himself entangled in the marvelous spy system of the
+warring European nations. These systems revealed their devious and dark
+ways, ramifying as they did tentacle-like even across the ocean in
+their efforts to gain their ends in neutral America. Not only so, but,
+as I shall some day endeavor to show later, when the ban of silence
+imposed by neutrality is raised after the war, many of the horrors of
+the war were brought home intimately to us.
+
+I have, after mature consideration, decided that even at present
+nothing but good can come from the publication at least of some part of
+the strange series of adventures through which Kennedy and I have just
+gone, especially those which might, if we had not succeeded, have
+caused most important changes in current history. As for the other
+adventures, no question can be raised about the propriety of their
+publication.
+
+At any rate, it came about that early in August, when the war cloud was
+just beginning to loom blackest, Kennedy was unexpectedly called into
+one of the strangest, most dangerous situations in which his peculiar
+and perilous profession had ever involved him.
+
+
+
+
+CHAPTER I
+
+THE WAR TERROR
+
+
+"I must see Professor Kennedy--where is he?--I must see him, for God's
+sake!"
+
+I was almost carried off my feet by the inrush of a wild-eyed girl,
+seemingly half crazed with excitement, as she cried out Craig's name.
+
+Startled by my own involuntary exclamation of surprise which followed
+the vision that shot past me as I opened our door in response to a
+sudden, sharp series of pushes at the buzzer, Kennedy bounded swiftly
+toward me, and the girl almost flung herself upon him.
+
+"Why, Miss--er--Miss--my dear young lady--what's the matter?" he
+stammered, catching her by the arm gently.
+
+As Kennedy forced our strange visitor into a chair, I observed that she
+was all a-tremble. Her teeth fairly chattered. Alternately her nervous,
+peaceless hands clutched at an imaginary something in the air, as if
+for support, then, finding none, she would let her wrists fall supine,
+while she gazed about with quivering lips and wild, restless eyes.
+Plainly, there was something she feared. She was almost over the verge
+of hysteria.
+
+She was a striking girl, of medium height and slender form, but it was
+her face that fascinated me, with its delicately molded features,
+intense unfathomable eyes of dark brown, and lips that showed her
+idealistic, high-strung temperament.
+
+"Please," he soothed, "get yourself together, please--try! What is the
+matter?"
+
+She looked about, as if she feared that the very walls had eyes and
+ears. Yet there seemed to be something bursting from her lips that she
+could not restrain.
+
+"My life," she cried wildly, "my life is at stake. Oh--help me, help
+me! Unless I commit a murder to-night, I shall be killed myself!"
+
+The words sounded so doubly strange from a girl of her evident
+refinement that I watched her narrowly, not sure yet but that we had a
+plain case of insanity to deal with.
+
+"A murder?" repeated Kennedy incredulously. "YOU commit a murder?"
+
+Her eyes rested on him, as if fascinated, but she did not flinch as she
+replied desperately, "Yes--Baron Kreiger--you know, the German diplomat
+and financier, who is in America raising money and arousing sympathy
+with his country."
+
+"Baron Kreiger!" exclaimed Kennedy in surprise, looking at her more
+keenly.
+
+We had not met the Baron, but we had heard much about him, young,
+handsome, of an old family, trusted already in spite of his youth by
+many of the more advanced of old world financial and political leaders,
+one who had made a most favorable impression on democratic America at a
+time when such impressions were valuable.
+
+Glancing from one of us to the other, she seemed suddenly, with a great
+effort, to recollect herself, for she reached into her chatelaine and
+pulled out a card from a case.
+
+It read simply, "Miss Paula Lowe."
+
+"Yes," she replied, more calmly now to Kennedy's repetition of the
+Baron's name, "you see, I belong to a secret group." She appeared to
+hesitate, then suddenly added, "I am an anarchist."
+
+She watched the effect of her confession and, finding the look on
+Kennedy's face encouraging rather than shocked, went on breathlessly:
+"We are fighting war with war--this iron-bound organization of men and
+women. We have pledged ourselves to exterminate all kings, emperors and
+rulers, ministers of war, generals--but first of all the financiers who
+lend money that makes war possible."
+
+She paused, her eyes gleaming momentarily with something like the
+militant enthusiasm that must have enlisted her in the paradoxical war
+against war.
+
+"We are at least going to make another war impossible!" she exclaimed,
+for the moment evidently forgetting herself.
+
+"And your plan?" prompted Kennedy, in the most matter-of-fact manner,
+as though he were discussing an ordinary campaign for social
+betterment. "How were you to--reach the Baron?"
+
+"We had a drawing," she answered with amazing calmness, as if the mere
+telling relieved her pent-up feelings. "Another woman and I were
+chosen. We knew the Baron's weakness for a pretty face. We planned to
+become acquainted with him--lure him on."
+
+Her voice trailed off, as if, the first burst of confidence over, she
+felt something that would lock her secret tighter in her breast.
+
+A moment later she resumed, now talking rapidly, disconnectedly, giving
+Kennedy no chance to interrupt or guide the conversation.
+
+"You don't know, Professor Kennedy," she began again, "but there are
+similar groups to ours in European countries and the plan is to strike
+terror and consternation everywhere in the world at once. Why, at our
+headquarters there have been drawn up plans and agreements with other
+groups and there are set down the time, place, and manner of all
+the--the removals."
+
+Momentarily she seemed to be carried away by something like the
+fanaticism of the fervor which had at first captured her, even still
+held her as she recited her incredible story.
+
+"Oh, can't you understand?" she went on, as if to justify herself. "The
+increase in armies, the frightful implements of slaughter, the total
+failure of the peace propaganda--they have all defied civilization!
+
+"And then, too, the old, red-blooded emotions of battle have all been
+eliminated by the mechanical conditions of modern warfare in which men
+and women are just so many units, automata. Don't you see? To fight war
+with its own weapons--that has become the only last resort."
+
+Her eager, flushed face betrayed the enthusiasm which had once carried
+her into the "Group," as she called it. I wondered what had brought her
+now to us.
+
+"We are no longer making war against man," she cried. "We are making
+war against picric acid and electric wires!"
+
+I confess that I could not help thinking that there was no doubt that
+to a certain type of mind the reasoning might appeal most strongly.
+
+"And you would do it in war time, too?" asked Kennedy quickly.
+
+She was ready with an answer. "King George of Greece was killed at the
+head of his troops. Remember Nazim Pasha, too. Such people are easily
+reached in time of peace and in time of war, also, by sympathizers on
+their own side. That's it, you see--we have followers of all
+nationalities."
+
+She stopped, her burst of enthusiasm spent. A moment later she leaned
+forward, her clean-cut profile showing her more earnest than before.
+"But, oh, Professor Kennedy," she added, "it is working itself out to
+be more terrible than war itself!"
+
+"Have any of the plans been carried out yet?" asked Craig, I thought a
+little superciliously, for there had certainly been no such wholesale
+assassination yet as she had hinted at.
+
+She seemed to catch her breath. "Yes," she murmured, then checked
+herself as if in fear of saying too much. "That is, I--I think so."
+
+I wondered if she were concealing something, perhaps had already had a
+hand in some such enterprise and it had frightened her.
+
+Kennedy leaned forward, observing the girl's discomfiture. "Miss Lowe,"
+he said, catching her eye and holding it almost hypnotically, "why have
+you come to see me?"
+
+The question, pointblank, seemed to startle her. Evidently she had
+thought to tell only as little as necessary, and in her own way. She
+gave a little nervous laugh, as if to pass it off. But Kennedy's eyes
+conquered.
+
+"Oh, can't you understand yet?" she exclaimed, rising passionately and
+throwing out her arms in appeal. "I was carried away with my hatred of
+war. I hate it yet. But now--the sudden realization of what this
+compact all means has--well, caused something in me to--to snap. I
+don't care what oath I have taken. Oh, Professor Kennedy, you--you must
+save him!"
+
+I looked up at her quickly. What did she mean? At first she had come to
+be saved herself. "You must save him!" she implored.
+
+Our door buzzer sounded.
+
+She gazed about with a hunted look, as if she felt that some one had
+even now pursued her and found out.
+
+"What shall I do?" she whispered. "Where shall I go?"
+
+"Quick--in here. No one will know," urged Kennedy, opening the door to
+his room. He paused for an instant, hurriedly. "Tell me--have you and
+this other woman met the Baron yet? How far has it gone?"
+
+The look she gave him was peculiar. I could not fathom what was going
+on in her mind. But there was no hesitation about her answer. "Yes,"
+she replied, "I--we have met him. He is to come back to New York from
+Washington to-day--this afternoon--to arrange a private loan of five
+million dollars with some bankers secretly. We were to see him
+to-night--a quiet dinner, after an automobile ride up the Hudson--"
+
+"Both of you?" interrupted Craig.
+
+"Yes--that--that other woman and myself," she repeated, with a peculiar
+catch in her voice. "To-night was the time fixed in the drawing for
+the--"
+
+The word stuck in her throat. Kennedy understood. "Yes, yes," he
+encouraged, "but who is the other woman?"
+
+Before she could reply, the buzzer had sounded again and she had
+retreated from the door. Quickly Kennedy closed it and opened the
+outside door.
+
+It was our old friend Burke of the Secret Service.
+
+Without a word of greeting, a hasty glance seemed to assure him that
+Kennedy and I were alone. He closed the door himself, and, instead of
+sitting down, came close to Craig.
+
+"Kennedy," he blurted out in a tone of suppressed excitement, "can I
+trust you to keep a big secret?"
+
+Craig looked at him reproachfully, but said nothing.
+
+"I beg your pardon--a thousand times," hastened Burke. "I was so
+excited, I wasn't thinking--"
+
+"Once is enough, Burke," laughed Kennedy, his good nature restored at
+Burke's crestfallen appearance.
+
+"Well, you see," went on the Secret Service man, "this thing is so very
+important that--well, I forgot."
+
+He sat down and hitched his chair close to us, as he went on in a
+lowered, almost awestruck tone.
+
+"Kennedy," he whispered, "I'm on the trail, I think, of something
+growing out of these terrible conditions in Europe that will tax the
+best in the Secret Service. Think of it, man. There's an organization,
+right here in this city, a sort of assassin's club, as it were, aimed
+at all the powerful men the world over. Why, the most refined and
+intellectual reformers have joined with the most red-handed anarchists
+and--"
+
+"Sh! not so loud," cautioned Craig. "I think I have one of them in the
+next room. Have they done anything yet to the Baron?"
+
+It was Burke's turn now to look from one to the other of us in
+unfeigned surprise that we should already know something of his secret.
+
+"The Baron?" he repeated, lowering his voice. "What Baron?"
+
+It was evident that Burke knew nothing, at least of this new plot which
+Miss Lowe had indicated. Kennedy beckoned him over to the window
+furthest from the door to his own room.
+
+"What have you discovered?" he asked, forestalling Burke in the
+questioning. "What has happened?"
+
+"You haven't heard, then?" replied Burke.
+
+Kennedy nodded negatively.
+
+"Fortescue, the American inventor of fortescite, the new explosive,
+died very strangely this morning."
+
+"Yes," encouraged Kennedy, as Burke came to a full stop to observe the
+effect of the information.
+
+"Most incomprehensible, too," he pursued. "No cause, apparently. But it
+might have been overlooked, perhaps, except for one thing. It wasn't
+known generally, but Fortescue had just perfected a successful
+electro-magnetic gun--powderless, smokeless, flashless, noiseless and
+of tremendous power. To-morrow he was to have signed the contract to
+sell it to England. This morning he is found dead and the final plans
+of the gun are gone!"
+
+Kennedy and Burke were standing mutely looking at each other.
+
+"Who is in the next room?" whispered Burke hoarsely, recollecting
+Kennedy's caution of silence.
+
+Kennedy did not reply immediately. He was evidently much excited by
+Burke's news of the wonderful electro-magnetic gun.
+
+"Burke," he exclaimed suddenly, "let's join forces. I think we are both
+on the trail of a world-wide conspiracy--a sort of murder syndicate to
+wipe out war!"
+
+Burke's only reply was a low whistle that involuntarily escaped him as
+he reached over and grasped Craig's hand, which to him represented the
+sealing of the compact.
+
+As for me, I could not restrain a mental shudder at the power that
+their first murder had evidently placed in the hands of the anarchists,
+if they indeed had the electro-magnetic gun which inventors had been
+seeking for generations. What might they not do with it--perhaps even
+use it themselves and turn the latest invention against society itself!
+
+Hastily Craig gave a whispered account of our strange visit from Miss
+Lowe, while Burke listened, open-mouthed.
+
+He had scarcely finished when he reached for the telephone and asked
+for long distance.
+
+"Is this the German embassy in Washington?" asked Craig a few moments
+later when he got his number. "This is Craig Kennedy, in New York. The
+United States Secret Service will vouch for me--mention to them Mr.
+Burke of their New York office who is here with me now. I understand
+that Baron Kreiger is leaving for New York to meet some bankers this
+afternoon. He must not do so. He is in the gravest danger if he--What?
+He left last night at midnight and is already here?"
+
+Kennedy turned to us blankly.
+
+The door to his room opened suddenly.
+
+There stood Miss Lowe, gazing wild-eyed at us. Evidently her
+supernervous condition had heightened the keenness of her senses. She
+had heard what we were saying. I tried to read her face. It was not
+fear that I saw there. It was rage; it was jealousy.
+
+"The traitress--it is Marie!" she shrieked.
+
+For a moment, obtusely, I did not understand.
+
+"She has made a secret appointment with him," she cried.
+
+At last I saw the truth. Paula Lowe had fallen in love with the man she
+had sworn to kill!
+
+
+
+
+CHAPTER II
+
+THE ELECTRO-MAGNETIC GUN
+
+
+"What shall we do?" demanded Burke, instantly taking in the dangerous
+situation that the Baron's sudden change of plans had opened up.
+
+"Call O'Connor," I suggested, thinking of the police bureau of missing
+persons, and reaching for the telephone.
+
+"No, no!" almost shouted Craig, seizing my arm. "The police will
+inevitably spoil it all. No, we must play a lone hand in this if we are
+to work it out. How was Fortescue discovered, Burke?"
+
+"Sitting in a chair in his laboratory. He must have been there all
+night. There wasn't a mark on him, not a sign of violence, yet his face
+was terribly drawn as though he were gasping for breath or his heart
+had suddenly failed him. So far, I believe, the coroner has no clue and
+isn't advertising the case."
+
+"Take me there, then," decided Craig quickly. "Walter, I must trust
+Miss Lowe to you on the journey. We must all go. That must be our
+starting point, if we are to run this thing down."
+
+I caught his significant look to me and interpreted it to mean that he
+wanted me to watch Miss Lowe especially. I gathered that taking her was
+in the nature of a third degree and as a result he expected to derive
+some information from her. Her face was pale and drawn as we four piled
+into a taxicab for a quick run downtown to the laboratory of Fortescue
+from which Burke had come directly to us with his story.
+
+"What do you know of these anarchists?" asked Kennedy of Burke as we
+sped along. "Why do you suspect them?"
+
+It was evident that he was discussing the case so that Paula could
+overhear, for a purpose.
+
+"Why, we received a tip from abroad--I won't say where," replied Burke
+guardedly, taking his cue. "They call themselves the 'Group,' I
+believe, which is a common enough term among anarchists. It seems they
+are composed of terrorists of all nations."
+
+"The leader?" inquired Kennedy, leading him on.
+
+"There is one, I believe, a little florid, stout German. I think he is
+a paranoiac who believes there has fallen on himself a divine mission
+to end all warfare. Quite likely he is one of those who have fled to
+America to avoid military service. Perhaps, why certainly, you must
+know him--Annenberg, an instructor in economics now at the University?"
+
+Craig nodded and raised his eyebrows in mild surprise. We had indeed
+heard of Annenberg and some of his radical theories which had sometimes
+quite alarmed the conservative faculty. I felt that this was getting
+pretty close home to us now.
+
+"How about Mrs. Annenberg?" Craig asked, recalling the clever young
+wife of the middle-aged professor.
+
+At the mere mention of the name, I felt a sort of start in Miss Lowe,
+who was seated next to me in the taxicab. She had quickly recovered
+herself, but not before I saw that Kennedy's plan of breaking down the
+last barrier of her reserve was working.
+
+"She is one of them, too," Burke nodded. "I have had my men out
+shadowing them and their friends. They tell me that the Annenbergs hold
+salons--I suppose you would call them that--attended by numbers of men
+and women of high social and intellectual position who dabble in
+radicalism and all sorts of things."
+
+"Who are the other leaders?" asked Craig. "Have you any idea?"
+
+"Some idea," returned Burke. "There seems to be a Frenchman, a tall,
+wiry man of forty-five or fifty with a black mustache which once had a
+military twist. There are a couple of Englishmen. Then there are five
+or six Americans who seem to be active. One, I believe, is a young
+woman."
+
+Kennedy checked him with a covert glance, but did not betray by a
+movement of a muscle to Miss Lowe that either Burke or himself
+suspected her of being the young woman in question.
+
+"There are three Russians," continued Burke, "all of whom have escaped
+from Siberia. Then there is at least one Austrian, a Spaniard from the
+Ferrer school, and Tomasso and Enrico, two Italians, rather heavily
+built, swarthy, bearded. They look the part. Of course there are
+others. But these in the main, I think, compose what might be called
+'the inner circle' of the 'Group.'"
+
+It was indeed an alarming, terrifying revelation, as we began to
+realize that Miss Lowe had undoubtedly been telling the truth. Not
+alone was there this American group, evidently, but all over Europe the
+lines of the conspiracy had apparently spread. It was not a casual
+gathering of ordinary malcontents. It went deeper than that. It
+included many who in their disgust at war secretly were not unwilling
+to wink at violence to end the curse. I could not but reflect on the
+dangerous ground on which most of them were treading, shaking the basis
+of all civilization in order to cut out one modern excrescence.
+
+The big fact to us, just at present, was that this group had made
+America its headquarters, that plans had been studiously matured and
+even reduced to writing, if Paula were to be believed. Everything had
+been carefully staged for a great simultaneous blow or series of blows
+that would rouse the whole world.
+
+As I watched I could not escape observing that Miss Lowe followed Burke
+furtively now, as though he had some uncanny power.
+
+Fortescue's laboratory was in an old building on a side street several
+blocks from the main thoroughfares of Manhattan. He had evidently
+chosen it, partly because of its very inaccessibility in order to
+secure the quiet necessary for his work.
+
+"If he had any visitors last night," commented Kennedy when our cab at
+last pulled up before the place, "they might have come and gone
+unnoticed."
+
+We entered. Nothing had been disturbed in the laboratory by the coroner
+and Kennedy was able to gain a complete idea of the case rapidly,
+almost as well as if we had been called in immediately.
+
+Fortescue's body, it seemed, had been discovered sprawled out in a big
+armchair, as Burke had said, by one of his assistants only a few hours
+before when he had come to the laboratory in the morning to open it.
+Evidently he had been there undisturbed all night, keeping a gruesome
+vigil over his looted treasure house.
+
+As we gleaned the meager facts, it became more evident that whoever had
+perpetrated the crime must have had the diabolical cunning to do it in
+some ordinary way that aroused no suspicion on the part of the victim,
+for there was no sign of any violence anywhere.
+
+As we entered the laboratory, I noted an involuntary shudder on the
+part of Paula Lowe, but, as far as I knew, it was no more than might
+have been felt by anyone under the circumstances.
+
+Fortescue's body had been removed from the chair in which it had been
+found and lay on a couch at the other end of the room, covered merely
+by a sheet. Otherwise, everything, even the armchair, was undisturbed.
+
+Kennedy pulled back a corner of the sheet, disclosing the face,
+contorted and of a peculiar, purplish hue from the congested blood
+vessels. He bent over and I did so, too. There was an unmistakable odor
+of tobacco on him. A moment Kennedy studied the face before us, then
+slowly replaced the sheet.
+
+Miss Lowe had paused just inside the door and seemed resolutely bound
+not to look at anything. Kennedy meanwhile had begun a most minute
+search of the table and floor of the laboratory near the spot where the
+armchair had been sitting.
+
+In my effort to glean what I could from her actions and expressions I
+did not notice that Craig had dropped to his knees and was peering into
+the shadow under the laboratory table. When at last he rose and
+straightened himself up, however, I saw that he was holding in the palm
+of his hand a half-smoked, gold-tipped cigarette, which had evidently
+fallen on the floor beneath the table where it had burned itself out,
+leaving a blackened mark on the wood.
+
+An instant afterward he picked out from the pile of articles found in
+Fortescue's pockets and lying on another table a silver cigarette case.
+He snapped it open. Fortescue's cigarettes, of which there were perhaps
+a half dozen in the case, were cork-tipped.
+
+Some one had evidently visited the inventor the night before, had
+apparently offered him a cigarette, for there were any number of the
+cork-tipped stubs lying about. Who was it? I caught Paula looking with
+fascinated gaze at the gold-tipped stub, as Kennedy carefully folded it
+up in a piece of paper and deposited it in his pocket. Did she know
+something about the case, I wondered?
+
+Without a word, Kennedy seemed to take in the scant furniture of the
+laboratory at a glance and a quick step or two brought him before a
+steel filing cabinet. One drawer, which had not been closed as tightly
+as the rest, projected a bit. On its face was a little typewritten card
+bearing the inscription: "E-M GUN."
+
+He pulled the drawer open and glanced over the data in it.
+
+"Just what is an electro-magnetic gun?" I asked, interpreting the
+initials on the drawer.
+
+"Well," he explained as he turned over the notes and sketches, "the
+primary principle involved in the construction of such a gun consists
+in impelling the projectile by the magnetic action of a solenoid, the
+sectional coils or helices of which are supplied with current through
+devices actuated by the projectile itself. In other words, the sections
+of helices of the solenoid produce an accelerated motion of the
+projectile by acting successively on it, after a principle involved in
+the construction of electro-magnetic rock drills and dispatch tubes.
+
+"All projectiles used in this gun of Fortescue's evidently must have
+magnetic properties and projectiles of iron or containing large
+portions of iron are necessary. You see, many coils are wound around
+the barrel of the gun. As the projectile starts it does so under the
+attraction of those coils ahead which the current makes temporary
+magnets. It automatically cuts off the current from those coils that it
+passes, allowing those further on only to attract it, and preventing
+those behind from pulling it back."
+
+He paused to study the scraps of plans. "Fortescue had evidently also
+worked out a way of changing the poles of the coils as the projectile
+passed, causing them then to repel the projectile, which must have
+added to its velocity. He seems to have overcome the practical
+difficulty that in order to obtain service velocities with service
+projectiles an enormous number of windings and a tremendously long
+barrel are necessary as well as an abnormally heavy current beyond the
+safe carrying capacity of the solenoid which would raise the
+temperature to a point that would destroy the coils."
+
+He continued turning over the prints and notes in the drawer. When he
+finished, he looked up at us with an expression that indicated that he
+had merely satisfied himself of something he had already suspected.
+
+"You were right, Burke," he said. "The final plans are gone."
+
+Burke, who, in the meantime, had been telephoning about the city in a
+vain effort to locate Baron Kreiger, both at such banking offices in
+Wall Street as he might be likely to visit and at some of the hotels
+most frequented by foreigners, merely nodded. He was evidently at a
+loss completely how to proceed.
+
+In fact, there seemed to be innumerable problems--to warn Baron
+Kreiger, to get the list of the assassinations, to guard Miss Lowe
+against falling into the hands of her anarchist friends again, to find
+the murderer of Fortescue, to prevent the use of the electro-magnetic
+gun, and, if possible, to seize the anarchists before they had a chance
+to carry further their plans.
+
+"There is nothing more that we can do here," remarked Craig briskly,
+betraying no sign of hesitation. "I think the best thing we can do is
+to go to my own laboratory. There at least there is something I must
+investigate sooner or later."
+
+No one offering either a suggestion or an objection, we four again
+entered our cab. It was quite noticeable now that the visit had shaken
+Paula Lowe, but Kennedy still studiously refrained from questioning
+her, trusting that what she had seen and heard, especially Burke's
+report as to Baron Kreiger, would have its effect.
+
+Like everyone visiting Craig's laboratory for the first time, Miss Lowe
+seemed to feel the spell of the innumerable strange and uncanny
+instruments which he had gathered about him in his scientific warfare
+against crime. I could see that she was becoming more and more nervous,
+perhaps fearing even that in some incomprehensible way he might read
+her own thoughts. Yet one thing I did not detect. She showed no
+disposition to turn back on the course on which she had entered by
+coming to us in the first place.
+
+Kennedy was quickly and deftly testing the stub of the little thin,
+gold-tipped cigarette.
+
+"Excessive smoking," he remarked casually, "causes neuroses of the
+heart and tobacco has a specific affinity for the coronary arteries as
+well as a tremendous effect on the vagus nerve. But I don't think this
+was any ordinary smoke."
+
+He had finished his tests and a quiet smile of satisfaction flitted
+momentarily over his face. We had been watching him anxiously,
+wondering what he had found.
+
+As he looked up he remarked to us, with his eyes fixed on Miss Lowe,
+"That was a ladies' cigarette. Did you notice the size? There has been
+a woman in this case--presumably."
+
+The girl, suddenly transformed by the rapid-fire succession of
+discoveries, stood before us like a specter.
+
+"The 'Group,' as anarchists call it," pursued Craig, "is the loosest
+sort of organization conceivable, I believe, with no set membership, no
+officers, no laws--just a place of meeting with no fixity, where the
+comrades get together. Could you get us into the inner circle, Miss
+Lowe?"
+
+Her only answer was a little suppressed scream. Kennedy had asked the
+question merely for its effect, for it was only too evident that there
+was no time, even if she could have managed it, for us to play the
+"stool pigeon."
+
+Kennedy, who had been clearing up the materials he had used in the
+analysis of the cigarette, wheeled about suddenly. "Where is the
+headquarters of the inner circle?" he shot out.
+
+Miss Lowe hesitated. That had evidently been one of the things she had
+determined not to divulge.
+
+"Tell me," insisted Kennedy. "You must!"
+
+If it had been Burke's bulldozing she would never have yielded. But as
+she looked into Kennedy's eyes she read there that he had long since
+fathomed the secret of her wildly beating heart, that if she would
+accomplish the purpose of saving the Baron she must stop at nothing.
+
+"At--Maplehurst," she answered in a low tone, dropping her eyes from
+his penetrating gaze, "Professor Annenberg's home--out on Long Island."
+
+"We must act swiftly if we are to succeed," considered Kennedy, his
+tone betraying rather sympathy with than triumph over the wretched girl
+who had at last cast everything in the balance to outweigh the terrible
+situation into which she had been drawn. "To send Miss Lowe for that
+fatal list of assassinations is to send her either back into the power
+of this murderous group and let them know that she has told us, or
+perhaps to involve her again in the completion of their plans."
+
+She sank back into a chair in complete nervous and physical collapse,
+covering her face with her hands at the realization that in her
+new-found passion to save the Baron she had bared her sensitive soul
+for the dissection of three men whom she had never seen before.
+
+"We must have that list," pursued Kennedy decisively. "We must visit
+Annenberg's headquarters."
+
+"And I?" she asked, trembling now with genuine fear at the thought that
+he might ask her to accompany us as he had on our visit to Fortescue's
+laboratory that morning.
+
+"Miss Lowe," said Kennedy, bending over her, "you have gone too far now
+ever to turn back. You are not equal to the trip. Would you like to
+remain here? No one will suspect. Here at least you will be safe until
+we return."
+
+Her answer was a mute expression of thanks and confidence.
+
+
+
+
+CHAPTER III
+
+THE MURDER SYNDICATE
+
+
+Quickly now Craig completed his arrangements for the visit to the
+headquarters of the real anarchist leader. Burke telephoned for a
+high-powered car, while Miss Lowe told frankly of the habits of
+Annenberg and the chances of finding his place unguarded, which were
+good in the daytime. Kennedy's only equipment for the excursion
+consisted in a small package which he took from a cabinet at the end of
+the room, and, with a parting reassurance to Paula Lowe, we were soon
+speeding over the bridge to the borough across the river.
+
+We realized that it might prove a desperate undertaking, but the crisis
+was such that it called for any risk.
+
+Our quest took us to a rather dilapidated old house on the outskirts of
+the little Long Island town. The house stood alone, not far from the
+tracks of a trolley that ran at infrequent intervals. Even a hasty
+reconnoitering showed that to stop our motor at even a reasonable
+distance from it was in itself to arouse suspicion.
+
+Although the house seemed deserted, Craig took no chances, but directed
+the car to turn at the next crossroad and then run back along a road
+back of and parallel to that on which Annenberg's was situated. It was
+perhaps a quarter of a mile away, across an open field, that we stopped
+and ran the car up along the side of the road in some bushes.
+Annenberg's was plainly visible and it was not at all likely that
+anyone there would suspect trouble from that quarter.
+
+A hasty conference with Burke followed, in which Kennedy unwrapped his
+small package, leaving part of its contents with him, and adding
+careful instructions.
+
+Then Kennedy and I retraced our steps down the road, across by the
+crossroad, and at last back to the mysterious house.
+
+To all appearance there had been no need of such excessive caution. Not
+a sound or motion greeted us as we entered the gate and made our way
+around to the rear of the house. The very isolation of the house was
+now our protection, for we had no inquisitive neighbors to watch us for
+the instant when Kennedy, with the dexterity of a yeggman, inserted his
+knife between the sashes of the kitchen window and turned the catch
+which admitted us.
+
+We made our way on cautious tiptoe through a dining room to a living
+room, and, finding nothing, proceeded upstairs. There was not a soul,
+apparently, in the house, nor in fact anything to indicate that it was
+different from most small suburban homes, until at last we mounted to
+the attic.
+
+It was finished off in one large room across the back of the house and
+two in front. As we opened the door to the larger room, we could only
+gaze about in surprise. This was the rendezvous, the arsenal, literary,
+explosive and toxicological of the "Group." Ranged on a table were all
+the materials for bomb-making, while in a cabinet I fancied there were
+poisons enough to decimate a city.
+
+On the walls were pictures, mostly newspaper prints, of the assassins
+of McKinley, of King Humbert, of the King of Greece, of King Carlos and
+others, interspersed with portraits of anarchist and anti-militarist
+leaders of all lands.
+
+Kennedy sniffed. Over all I, too, could catch the faint odor of stale
+tobacco. No time was to be lost, however, and while Craig set to work
+rapidly going through the contents of a desk in the corner, I glanced
+over the contents of a drawer of a heavy mission table.
+
+"Here's some of Annenberg's literature," I remarked, coming across a
+small pile of manuscript, entitled "The Human Slaughter House."
+
+"Read it," panted Kennedy, seeing that I had about completed my part of
+the job. "It may give a clue."
+
+Hastily I scanned the mad, frantic indictment of war, while Craig
+continued in his search:
+
+"I see wild beasts all around me, distorted unnaturally, in a life and
+death struggle, with bloodshot eyes, with foaming, gnashing mouths.
+They attack and kill one another and try to mangle each other. I leap
+to my feet. I race out into the night and tread on quaking flesh, step
+on hard heads, and stumble over weapons and helmets. Something is
+clutching at my feet like hands, so that I race away like a hunted deer
+with the hounds at his heels--and ever over more bodies--breathless...
+out of one field into another. Horror is crooning over my head. Horror
+is crooning beneath my feet. And nothing but dying, mangled flesh!
+
+"Of a sudden I see nothing but blood before me. The heavens have opened
+and the red blood pours in through the windows. Blood wells up on an
+altar. The walls run blood from the ceiling to the floor and... a giant
+of blood stands before me. His beard and his hair drip blood. He seats
+himself on the altar and laughs from thick lips. The black executioner
+raises his sword and whirls it above my head. Another moment and my
+head will roll down on the floor. Another moment and the red jet will
+spurt from my neck.
+
+"Murderers! Murderers! None other than murderers!"
+
+I paused in the reading. "There's nothing here," I remarked, glancing
+over the curious document for a clue, but finding none.
+
+"Well," remarked Craig contemplatively, "one can at least easily
+understand how sensitive and imaginative people who have fallen under
+the influence of one who writes in that way can feel justified in
+killing those responsible for bringing such horrors on the human race.
+Hello--what's this?"
+
+He had discovered a false back of one of the drawers in the desk and
+had jimmied it open. On the top of innumerable papers lay a large linen
+envelope. On its face it bore in typewriting, just like the card on the
+drawer at Fortescue's, "E-M GUN."
+
+"It is the original envelope that contained the final plans of the
+electro-magnetic gun," he explained, opening it.
+
+The envelope was empty. We looked at each other a moment in silence.
+What had been done with the plans?
+
+Suddenly a bell rang, startling me beyond measure. It was, however,
+only the telephone, of which an extension reached up into the
+attic-arsenal. Some one, who did not know that we were there, was
+evidently calling up.
+
+Kennedy quickly unhooked the receiver with a hasty motion to me to be
+silent.
+
+"Hello," I heard him answer. "Yes, this is it."
+
+He had disguised his voice. I waited anxiously and watched his face to
+gather what response he received.
+
+"The deuce!" he exclaimed, with his hand over the transmitter so that
+his voice would not be heard at the other end of the line.
+
+"What's the matter?" I asked eagerly.
+
+"It was Mrs. Annenberg--I am sure. But she was too keen for me. She
+caught on. There must be some password or form of expression that they
+use, which we don't know, for she hung up the receiver almost as soon
+as she heard me."
+
+Kennedy waited a minute or so. Then he whistled into the transmitter.
+It was done apparently to see whether there was anyone listening. But
+there was no answer.
+
+"Operator, operator!" he called insistently, moving the hook up and
+down. "Yes, operator. Can you tell me what number that was which just
+called?"
+
+He waited impatiently.
+
+"Bleecker--7l80," he repeated after the girl. "Thank you. Information,
+please."
+
+Again we waited, as Craig tried to trace the call up.
+
+"What is the street address of Bleecker, 7180?" he asked. "Five hundred
+and one East Fifth--a tenement. Thank you."
+
+"A tenement?" I repeated blankly.
+
+"Yes," he cried, now for the first time excited. "Don't you begin to
+see the scheme? I'll wager that Baron Kreiger has been lured to New
+York to purchase the electro-magnetic gun which they have stolen from
+Fortescue and the British. That is the bait that is held out to him by
+the woman. Call up Miss Lowe at the laboratory and see if she knows the
+place."
+
+I gave central the number, while he fell to at the little secret drawer
+of the desk again. The grinding of the wheels of a passing trolley
+interfered somewhat with giving the number and I had to wait a moment.
+
+"Ah--Walter--here's the list!" almost shouted Kennedy, as he broke open
+a black-japanned dispatch box in the desk.
+
+I bent over it, as far as the slack of the telephone wire of the
+receiver at my ear would permit. Annenberg had worked with amazing care
+and neatness on the list, even going so far as to draw at the top, in
+black, a death's head. The rest of it was elaborately prepared in
+flaming red ink.
+
+Craig gasped to observe the list of world-famous men marked for
+destruction in London, Paris, Berlin, Rome, Vienna, St. Petersburg, and
+even in New York and Washington.
+
+"What is the date set?" I asked, still with my ear glued to the
+receiver.
+
+"To-night and to-morrow," he replied, stuffing the fateful sheet into
+his pocket.
+
+Rummaging about in the drawer of the table, I had come to a package of
+gold-tipped cigarettes which had interested me and I had left them out.
+Kennedy was now looking at them curiously.
+
+"What is to be the method, do you suppose?" I asked.
+
+"By a poison that is among the most powerful, approaching even
+cyanogen," he replied confidently, tapping the cigarettes. "Do you
+smell the odor in this room? What is it like?"
+
+"Stale tobacco," I replied.
+
+"Exactly--nicotine. Two or three drops on the mouth-end of a cigar or
+cigarette. The intended victim thinks it is only natural. But it is the
+purest form of the deadly alkaloid--fatal in a few minutes, too."
+
+He examined the thin little cigarettes more carefully. "Nicotine," he
+went on, "was about the first alkaloid that was recovered from the body
+by chemical analysis in a homicide case. That is the penetrating,
+persistent odor you smelled at Fortescue's and also here. It's a very
+good poison--if you are not particular about being discovered. A pound
+of ordinary smoking tobacco contains from a half to an ounce of it. It
+is almost entirely consumed by combustion; otherwise a pipeful would be
+fatal. Of course they may have thought that investigators would believe
+that their victims were inveterate smokers. But even the worst tobacco
+fiend wouldn't show traces of the weed to such an extent."
+
+Miss Lowe answered at last and Kennedy took the telephone.
+
+"What is at five hundred and one East Fifth?" he asked.
+
+"A headquarters of the Group in the city," she answered. "Why?"
+
+"Well, I believe that the plans of that gun are there and that the
+Baron--"
+
+"You damned spies!" came a voice from behind us.
+
+Kennedy dropped the receiver, turning quickly, his automatic gleaming
+in his hand.
+
+There was just a glimpse of a man with glittering bright blue eyes that
+had an almost fiendish, baleful glare. An instant later the door which
+had so unexpectedly opened banged shut, we heard a key turn in the
+lock--and the man dropped to the floor before even Kennedy's automatic
+could test its ability to penetrate wood on a chance at hitting
+something the other side of it.
+
+We were prisoners!
+
+My mind worked automatically. At this very moment, perhaps, Baron
+Kreiger might be negotiating for the electro-magnetic gun. We had found
+out where he was, in all probability, but we were powerless to help
+him. I thought of Miss Lowe, and picked up the receiver which Kennedy
+had dropped.
+
+She did not answer. The wire had been cut. We were isolated!
+
+Kennedy had jumped to the window. I followed to restrain him, fearing
+that he had some mad scheme for climbing out. Instead, quickly he
+placed a peculiar arrangement, from the little package he had brought,
+holding it to his eye as if sighting it, his right hand grasping a
+handle as one holds a stereoscope. A moment later, as I examined it
+more closely, I saw that instead of looking at anything he had before
+him a small parabolic mirror turned away from him.
+
+His finger pressed alternately on a button on the handle and I could
+see that there flashed in the little mirror a minute incandescent lamp
+which seemed to have a special filament arrangement.
+
+The glaring sun was streaming in at the window and I wondered what
+could possibly be accomplished by the little light in competition with
+the sun itself.
+
+"Signaling by electric light in the daytime may sound to you
+ridiculous," explained Craig, still industriously flashing the light,
+"but this arrangement with Professor Donath's signal mirror makes it
+possible, all right.
+
+"I hadn't expected this, but I thought I might want to communicate with
+Burke quickly. You see, I sight the lamp and then press the button
+which causes the light in the mirror to flash. It seems a paradox that
+a light like this can be seen from a distance of even five miles and
+yet be invisible to one for whom it was not intended, but it is so. I
+use the ordinary Morse code--two seconds for a dot, six for a dash with
+a four-second interval."
+
+"What message did you send?" I asked.
+
+"I told him that Baron Kreiger was at five hundred and one East Fifth,
+probably; to get the secret service office in New York by wire and have
+them raid the place, then to come and rescue us. That was Annenberg. He
+must have come up by that trolley we heard passing just before."
+
+The minutes seemed ages as we waited for Burke to start the machinery
+of the raid and then come for us.
+
+"No--you can't have a cigarette--and if I had a pair of bracelets with
+me, I'd search you myself," we heard a welcome voice growl outside the
+door a few minutes later. "Look in that other pocket, Tom."
+
+The lock grated back and there stood Burke holding in a grip of steel
+the undersized Annenberg, while the chauffeur who had driven our car
+swung open the door.
+
+"I'd have been up sooner," apologized Burke, giving the anarchist an
+extra twist just to let him know that he was at last in the hands of
+the law, "only I figured that this fellow couldn't have got far away in
+this God-forsaken Ducktown and I might as well pick him up while I had
+a chance. That's a great little instrument of yours, Kennedy. I got
+you, fine."
+
+Annenberg, seeing we were now four to one, concluded that discretion
+was the better part of valor and ceased to struggle, though now and
+then I could see he glanced at Kennedy out of the corner of his eye. To
+every question he maintained a stolid silence.
+
+A few minutes later, with the arch anarchist safely pinioned between
+us, we were speeding back toward New York, laying plans for Burke to
+dispatch warnings abroad to those whose names appeared on the fatal
+list, and at the same time to round up as many of the conspirators as
+possible in America.
+
+As for Kennedy, his main interest now lay in Baron Kreiger and Paula.
+While she had been driven frantic by the outcome of the terrible pact
+into which she had been drawn, some one, undoubtedly, had been trying
+to sell Baron Kreiger the gun that had been stolen from the American
+inventor. Once they had his money and he had received the plans of the
+gun, a fatal cigarette would be smoked. Could we prevent it?
+
+On we tore back to the city, across the bridge and down through the
+canyons of East Side streets.
+
+At last we pulled up before the tenement at five hundred and one. As we
+did so, one of Burke's men jumped out of the doorway.
+
+"Are we in time?" shouted Burke.
+
+"It's an awful mix-up," returned the man. "I can't make anything out of
+it, so I ordered 'em all held here till you came."
+
+We pushed past without a word of criticism of his wonderful acumen.
+
+On the top floor we came upon a young man, bending over the form of a
+girl who had fainted. On the floor of the middle of the room was a mass
+of charred papers which had evidently burned a hole in the carpet
+before they had been stamped out. Near by was an unlighted cigarette,
+crushed flat on the floor.
+
+"How is she?" asked Kennedy anxiously of the young man, as he dropped
+down on the other side of the girl.
+
+It was Paula. She had fainted, but was just now coming out of the
+borderland of unconsciousness.
+
+"Was I in time? Had he smoked it?" she moaned weakly, as there swam
+before her eyes, evidently, a hazy vision of our faces.
+
+Kennedy turned to the young man.
+
+"Baron Kreiger, I presume?" he inquired.
+
+The young man nodded.
+
+"Burke of the Secret Service," introduced Craig, indicating our friend.
+"My name is Kennedy. Tell what happened."
+
+"I had just concluded a transaction," returned Kreiger in good but
+carefully guarded English. "Suddenly the door burst open. She seized
+these papers and dashed a cigarette out of my hands. The next instant
+she had touched a match to them and had fallen in a faint almost in the
+blaze. Strangest experience I ever had in my life. Then all these other
+fellows came bursting in--said they were Secret Service men, too."
+
+Kennedy had no time to reply, for a cry from Annenberg directed our
+attention to the next room where on a couch lay a figure all huddled up.
+
+As we looked we saw it was a woman, her head sweating profusely, and
+her hands cold and clammy. There was a strange twitching of the muscles
+of the face, the pupils of her eyes were widely dilated, her pulse weak
+and irregular. Evidently her circulation had failed so that it
+responded only feebly to stimulants, for her respiration was slow and
+labored, with loud inspiratory gasps.
+
+Annenberg had burst with superhuman strength from Burke's grasp and was
+kneeling by the side of his wife's deathbed.
+
+"It--was all Paula's fault--" gasped the woman. "I--knew I had
+better--carry it through--like the Fortescue visit--alone."
+
+I felt a sense of reassurance at the words. At least my suspicions had
+been unfounded. Paula was innocent of the murder of Fortescue.
+
+"Severe, acute nicotine poisoning," remarked Kennedy, as he rejoined us
+a moment later. "There is nothing we can do--now."
+
+Paula moved at the words, as though they had awakened a new energy in
+her. With a supreme effort she raised herself.
+
+"Then I--I failed?" she cried, catching sight of Kennedy.
+
+"No, Miss Lowe," he answered gently. "You won. The plans of the
+terrible gun are destroyed. The Baron is safe. Mrs. Annenberg has
+herself smoked one of the fatal cigarettes intended for him."
+
+Kreiger looked at us, uncomprehending. Kennedy picked up the crushed,
+unlighted cigarette and laid it in the palm of his hand beside another,
+half smoked, which he had found beside Mrs. Annenberg.
+
+"They are deadly," he said simply to Kreiger. "A few drops of pure
+nicotine hidden by that pretty gilt tip would have accomplished all
+that the bitterest anarchist could desire."
+
+All at once Kreiger seemed to realize what he had escaped so narrowly.
+He turned toward Paula. The revulsion of her feelings at seeing him
+safe was too much for her shattered nerves.
+
+With a faint little cry, she tottered.
+
+Before any of us could reach her, he had caught her in his arms and
+imprinted a warm kiss on the insensible lips.
+
+"Some water--quick!" he cried, still holding her close.
+
+
+
+
+CHAPTER IV
+
+THE AIR PIRATE
+
+
+Rounding up the "Group" took several days, and it proved to be a great
+story for the Star. I was pretty fagged when it was all over, but there
+was a great deal of satisfaction in knowing that we had frustrated one
+of the most daring anarchist plots of recent years.
+
+"Can you arrange to spend the week-end with me at Stuyvesant
+Verplanck's at Bluffwood?" asked Kennedy over the telephone, the
+afternoon that I had completed my work on the newspaper of undoing what
+Annenberg and the rest had attempted.
+
+"How long since society took you up?" I asked airily, adding, "Is it a
+large house party you are getting up?"
+
+"You have heard of the so-called 'phantom bandit' of Bluffwood, haven't
+you?" he returned rather brusquely, as though there was no time now for
+bantering.
+
+I confess that in the excitement of the anarchists I had forgotten it,
+but now I recalled that for several days I had been reading little
+paragraphs about robberies on the big estates on the Long Island shore
+of the Sound. One of the local correspondents had called the robber a
+"phantom bandit," but I had thought it nothing more than an attempt to
+make good copy out of a rather ordinary occurrence.
+
+"Well," he hurried on, "that's the reason why I have been 'taken up by
+society,' as you so elegantly phrase it. From the secret hiding-places
+of the boudoirs and safes of fashionable women at Bluffwood, thousands
+of dollars' worth of jewels and other trinkets have mysteriously
+vanished. Of course you'll come along. Why, it will be just the story
+to tone up that alleged page of society news you hand out in the Sunday
+Star. There--we're quits now. Seriously, though, Walter, it really
+seems to be a very baffling case, or rather series of cases. The whole
+colony out there is terrorized. They don't know who the robber is, or
+how he operates, or who will be the next victim, but his skill and
+success seem almost uncanny. Mr. Verplanck has put one of his cars at
+my disposal and I'm up here at the laboratory gathering some apparatus
+that may be useful. I'll pick you up anywhere between this and the
+Bridge--how about Columbus Circle in half an hour?"
+
+"Good," I agreed, deciding quickly from his tone and manner of
+assurance that it would be a case I could not afford to miss.
+
+The Stuyvesant Verplancks, I knew, were among the leaders of the rather
+recherche society at Bluffwood, and the pace at which Bluffwood moved
+and had its being was such as to guarantee a good story in one way or
+another.
+
+"Why," remarked Kennedy, as we sped out over the picturesque roads of
+the north shore of Long Island, "this fellow, or fellows, seems to have
+taken the measure of all the wealthy members of the exclusive
+organizations out there--the Westport Yacht Club, the Bluffwood Country
+Club, the North Shore Hunt, and all of them. It's a positive scandal,
+the ease with which he seems to come and go without detection, striking
+now here, now there, often at places that it seems physically
+impossible to get at, and yet always with the same diabolical skill and
+success. One night he will take some baubles worth thousands, the next
+pass them by for something apparently of no value at all, a piece of
+bric-a-brac, a bundle of letters, anything."
+
+"Seems purposeless, insane, doesn't it?" I put in.
+
+"Not when he always takes something--often more valuable than money,"
+returned Craig.
+
+He leaned back in the car and surveyed the glimpses of bay and
+countryside as we were whisked by the breaks in the trees.
+
+"Walter," he remarked meditatively, "have you ever considered the
+possibilities of blackmail if the right sort of evidence were obtained
+under this new 'white-slavery act'? Scandals that some of the fast set
+may be inclined to wink at, that at worst used to end in Reno, become
+felonies with federal prison sentences looming up in the background.
+Think it over."
+
+Stuyvesant Verplanck had telephoned rather hurriedly to Craig earlier
+in the day, retaining his services, but telling only in the briefest
+way of the extent of the depredations, and hinting that more than
+jewelry might be at stake.
+
+It was a pleasant ride, but we finished it in silence. Verplanck was,
+as I recalled, a large masterful man, one of those who demanded and
+liked large things--such as the estate of several hundred acres which
+we at last entered.
+
+It was on a neck of land with the restless waters of the Sound on one
+side and the calmer waters of the bay on the other. Westport Bay lay in
+a beautifully wooded, hilly country, and the house itself was on an
+elevation, with a huge sweep of terraced lawn before it down to the
+water's edge. All around, for miles, were other large estates, a
+veritable colony of wealth.
+
+As we pulled up under the broad stone porte-cochere, Verplanck, who had
+been expecting us, led the way into his library, a great room,
+literally crowded with curios and objects of art which he had collected
+on his travels. It was a superb mental workshop, overlooking the bay,
+with a stretch of several miles of sheltered water.
+
+"You will recall," began Verplanck, wasting no time over preliminaries,
+but plunging directly into the subject, "that the prominent robberies
+of late have been at seacoast resorts, especially on the shores of Long
+Island Sound, within, say, a hundred miles of New York. There has been
+a great deal of talk about dark and muffled automobiles that have
+conveyed mysterious parties swiftly and silently across country.
+
+"My theory," he went on self-assertively, "is that the attack has been
+made always along water routes. Under shadow of darkness, it is easy to
+slip into one of the sheltered coves or miniature fiords with which the
+north coast of the Island abounds, land a cut-throat crew primed with
+exact information of the treasure on some of these estates. Once the
+booty is secured, the criminal could put out again into the Sound
+without leaving a clue."
+
+He seemed to be considering his theory. "Perhaps the robberies last
+summer at Narragansett, Newport, and a dozen other New England places
+were perpetrated by the same cracksman. I believe," he concluded,
+lowering his voice, "that there plies to-day on the wide waters of the
+Sound a slim, swift motor boat which wears the air of a pleasure craft,
+yet is as black a pirate as ever flew the Jolly Roger. She may at this
+moment be anchored off some exclusive yacht club, flying the
+respectable burgee of the club--who knows?"
+
+He paused as if his deductions settled the case so far. He would have
+resumed in the same vein, if the door had not opened. A lady in a
+cobwebby gown entered the room. She was of middle age, but had retained
+her youth with a skill that her sisters of less leisure always envy.
+Evidently she had not expected to find anyone, yet nothing seemed to
+disconcert her.
+
+"Mrs. Verplanck," her husband introduced, "Professor Kennedy and his
+associate, Mr. Jameson--those detectives we have heard about. We were
+discussing the robberies."
+
+"Oh, yes," she said, smiling, "my husband has been thinking of forming
+himself into a vigilance committee. The local authorities are all at
+sea."
+
+I thought there was a trace of something veiled in the remark and
+fancied, not only then but later, that there was an air of constraint
+between the couple.
+
+"You have not been robbed yourself?" queried Craig tentatively.
+
+"Indeed we have," exclaimed Verplanck quickly. "The other night I was
+awakened by the noise of some one down here in this very library. I
+fired a shot, wild, and shouted, but before I could get down here the
+intruder had fled through a window, and half rolling down the terraces.
+Mrs. Verplanck was awakened by the rumpus and both of us heard a
+peculiar whirring noise."
+
+"Like an automobile muffled down," she put in.
+
+"No," he asserted vigorously, "more like a powerful motor boat, one
+with the exhaust under water."
+
+"Well," she shrugged, "at any rate, we saw no one."
+
+"Did the intruder get anything?"
+
+"That's the lucky part. He had just opened this safe apparently and
+begun to ransack it. This is my private safe. Mrs. Verplanck has
+another built into her own room upstairs where she keeps her jewels."
+
+"It is not a very modern safe, is it?" ventured Kennedy. "The fellow
+ripped off the outer casing with what they call a 'can-opener.'"
+
+"No. I keep it against fire rather than burglars. But he overlooked a
+box of valuable heirlooms, some silver with the Verplanck arms. I think
+I must have scared him off just in time. He seized a package in the
+safe, but it was only some business correspondence. I don't relish
+having lost it, particularly. It related to a gentlemen's agreement a
+number of us had in the recent cotton corner. I suppose the Government
+would like to have it. But--here's the point. If it is so easy to get
+in and get away, no one in Bluffwood is safe."
+
+"Why, he robbed the Montgomery Carter place the other night," remarked
+Mrs. Verplanck, "and almost got a lot of old Mrs. Carter's jewels as
+well as stuff belonging to her son, Montgomery, Junior. That was the
+first robbery. Mr. Carter, that is Junior--Monty, everyone calls
+him--and his chauffeur almost captured the fellow, but he managed to
+escape in the woods."
+
+"In the woods?" repeated Craig.
+
+Mrs. Verplanck nodded. "But they saved the loot he was about to take."
+
+"Oh, no one is safe any more," reiterated Verplanck. "Carter seems to
+be the only one who has had a real chance at him, and he was able to
+get away neatly."
+
+"But he's not the only one who got off without a loss," she put in
+significantly. "The last visit--" Then she paused.
+
+"Where was the last attempt?" asked Kennedy.
+
+"At the house of Mrs. Hollingsworth--around the point on this side of
+the bay. You can't see it from here."
+
+"I'd like to go there," remarked Kennedy.
+
+"Very well. Car or boat?"
+
+"Boat, I think."
+
+"Suppose we go in my little runabout, the Streamline II? She's as fast
+as any ordinary automobile."
+
+"Very good. Then we can get an idea of the harbor."
+
+"I'll telephone first that we are coming," said Verplanck.
+
+"I think I'll go, too," considered Mrs. Verplanck, ringing for a heavy
+wrap.
+
+"Just as you please," said Verplanck.
+
+The Streamline was a three-stepped boat which. Verplanck had built for
+racing, a beautiful craft, managed much like a racing automobile. As
+she started from the dock, the purring drone of her eight cylinders
+sent her feathering over the waves like a skipping stone. She sank back
+into the water, her bow leaping upward, a cloud of spray in her wake,
+like a waterspout.
+
+Mrs. Hollingsworth was a wealthy divorcee, living rather quietly with
+her two children, of whom the courts had awarded her the care. She was
+a striking woman, one of those for whom the new styles of dress seem
+especially to have been designed. I gathered, however, that she was not
+on very good terms with the little Westport clique in which the
+Verplancks moved, or at least not with Mrs. Verplanck. The two women
+seemed to regard each other rather coldly, I thought, although Mr.
+Verplanck, man-like, seemed to scorn any distinctions and was more than
+cordial. I wondered why Mrs. Verplanck had come.
+
+The Hollingsworth house was a beautiful little place down the bay from
+the Yacht Club, but not as far as Verplanck's, or the Carter estate,
+which was opposite.
+
+"Yes," replied Mrs. Hollingsworth when the reason for our visit had
+been explained, "the attempt was a failure. I happened to be awake,
+rather late, or perhaps you would call it early. I thought I heard a
+noise as if some one was trying to break into the drawing-room through
+the window. I switched on all the lights. I have them arranged so for
+just that purpose of scaring off intruders. Then, as I looked out of my
+window on the second floor, I fancied I could see a dark figure slink
+into the shadow of the shrubbery at the side of the house. Then there
+was a whirr. It might have been an automobile, although it sounded
+differently from that--more like a motor boat. At any rate, there was
+no trace of a car that we could discover in the morning. The road had
+been oiled, too, and a car would have left marks. And yet some one was
+here. There were marks on the drawing-room window just where I heard
+the sounds."
+
+Who could it be? I asked myself as we left. I knew that the great army
+of chauffeurs was infested with thieves, thugs and gunmen. Then, too,
+there were maids, always useful as scouts for these corsairs who prey
+on the rich. Yet so adroitly had everything been done in these cases
+that not a clue seemed to have been left behind by which to trace the
+thief.
+
+We returned to Verplanck's in the Streamline in record time, dined, and
+then found McNeill, a local detective, waiting to add his quota of
+information. McNeill was of the square-toed, double-chinned,
+bull-necked variety, just the man to take along if there was any
+fighting. He had, however, very little to add to the solution of the
+mystery, apparently believing in the chauffeur-and-maid theory.
+
+It was too late to do anything more that night, and we sat on the
+Verplanck porch, overlooking the beautiful harbor. It was a black, inky
+night, with no moon, one of those nights when the myriad lights on the
+boats were mere points in the darkness. As we looked out over the
+water, considering the case which as yet we had hardly started on,
+Kennedy seemed engrossed in the study in black.
+
+"I thought I saw a moving light for an instant across the bay, above
+the boats, and as though it were in the darkness of the hills on the
+other side. Is there a road over there, above the Carter house?" he
+asked suddenly.
+
+"There is a road part of the way on the crest of the hill," replied
+Mrs. Verplanck. "You can see a car on it, now and then, through the
+trees, like a moving light."
+
+"Over there, I mean," reiterated Kennedy, indicating the light as it
+flashed now faintly, then disappeared, to reappear further along, like
+a gigantic firefly in the night.
+
+"N-no," said Verplanck. "I don't think the road runs down as far as
+that. It is further up the bay."
+
+"What is it then?" asked Kennedy, half to himself. "It seems to be
+traveling rapidly. Now it must be about opposite the Carter house.
+There--it has gone."
+
+We continued to watch for several minutes, but it did not reappear.
+Could it have been a light on the mast of a boat moving rapidly up the
+bay and perhaps nearer to us than we suspected? Nothing further
+happened, however, and we retired early, expecting to start with fresh
+minds on the case in the morning. Several watchmen whom Verplanck
+employed both on the shore and along the driveways were left guarding
+every possible entrance to the estate.
+
+Yet the next morning as we met in the cheery east breakfast room,
+Verplanck's gardener came in, hat in hand, with much suppressed
+excitement.
+
+In his hand he held an orange which he had found in the shrubbery
+underneath the windows of the house. In it was stuck a long nail and to
+the nail was fastened a tag.
+
+Kennedy read it quickly.
+
+"If this had been a bomb, you and your detectives would never have
+known what struck you.
+
+"AQUAERO."
+
+
+
+
+CHAPTER V
+
+THE ULTRA-VIOLET RAY
+
+
+"Good Gad, man!" exclaimed Verplanck, who had read it over Craig's
+shoulder. "What do you make of THAT?"
+
+Kennedy merely shook his head. Mrs. Verplanck was the calmest of all.
+
+"The light," I cried. "You remember the light? Could it have been a
+signal to some one on this side of the bay, a signal light in the
+woods?"
+
+"Possibly," commented Kennedy absently, adding, "Robbery with this
+fellow seems to be an art as carefully strategized as a promoter's plan
+or a merchant's trade campaign. I think I'll run over this morning and
+see if there is any trace of anything on the Carter estate."
+
+Just then the telephone rang insistently. It was McNeill, much excited,
+though he had not heard of the orange incident. Verplanck answered the
+call.
+
+"Have you heard the news?" asked McNeill. "They report this morning
+that that fellow must have turned up last night at Belle Aire."
+
+"Belle Aire? Why, man, that's fifty miles away and on the other side of
+the island. He was here last night," and Verplanck related briefly the
+find of the morning. "No boat could get around the island in that time
+and as for a car--those roads are almost impossible at night."
+
+"Can't help it," returned McNeill doggedly. "The Halstead estate out at
+Belle Aire was robbed last night. It's spooky all right."
+
+"Tell McNeill I want to see him--will meet him in the village
+directly," cut in Craig before Verplanck had finished.
+
+We bolted a hasty breakfast and in one of Verplanck's cars hurried to
+meet McNeill.
+
+"What do you intend doing?" he asked helplessly, as Kennedy finished
+his recital of the queer doings of the night before.
+
+"I'm going out now to look around the Carter place. Can you come along?"
+
+"Surely," agreed McNeill, climbing into the car. "You know him?"
+
+"No."
+
+"Then I'll introduce you. Queer chap, Carter. He's a lawyer, although I
+don't think he has much practice, except managing his mother's estate."
+
+McNeill settled back in the luxurious car with an exclamation of
+satisfaction.
+
+"What do you think of Verplanck?" he asked.
+
+"He seems to me to be a very public-spirited man," answered Kennedy
+discreetly.
+
+That, however, was not what McNeill meant and he ignored it. And so for
+the next ten minutes we were entertained with a little retail scandal
+of Westport and Bluffwood, including a tale that seemed to have gained
+currency that Verplanck and Mrs. Hollingsworth were too friendly to
+please Mrs. Verplanck. I set the whole thing down to the hostility and
+jealousy of the towns people who misinterpret everything possible in
+the smart set, although I could not help recalling how quickly she had
+spoken when we had visited the Hollingsworth house in the Streamline
+the day before.
+
+Montgomery Carter happened to be at home and, at least openly,
+interposed no objection to our going about the grounds.
+
+"You see," explained Kennedy, watching the effect of his words as if to
+note whether Carter himself had noticed anything unusual the night
+before, "we saw a light moving over here last night. To tell the truth,
+I half expected you would have a story to add to ours, of a second
+visit."
+
+Carter smiled. "No objection at all. I'm simply nonplussed at the nerve
+of this fellow, coming back again. I guess you've heard what a narrow
+squeak he had with me. You're welcome to go anywhere, just so long as
+you don't disturb my study down there in the boathouse. I use that
+because it overlooks the bay--just the place to study over knotty legal
+problems."
+
+Back of, or in front of the Carter house, according as you fancied it
+faced the bay or not, was the boathouse, built by Carter's father, who
+had been a great yachtsman in his day and commodore of the club. His
+son had not gone in much for water sports and had converted the corner
+underneath a sort of observation tower into a sort of country law
+office.
+
+"There has always seemed to me to be something strange about that
+boathouse since the old man died," remarked McNeill in a half whisper
+as we left Carter. "He always keeps it locked and never lets anyone go
+in there, although they say he has it fitted beautifully with hundreds
+of volumes of law books, too."
+
+Kennedy had been climbing the hill back of the house and now paused to
+look about. Below was the Carter garage.
+
+"By the way," exclaimed McNeill, as if he had at last hit on a great
+discovery, "Carter has a new chauffeur, a fellow named Wickham. I just
+saw him driving down to the village. He's a chap that it might pay us
+to watch--a newcomer, smart as a steel trap, they say, but not much of
+a talker."
+
+"Suppose you take that job--watch him," encouraged Kennedy. "We can't
+know too much about strangers here, McNeill."
+
+"That's right," agreed the detective. "I'll follow him back to the
+village and get a line on him."
+
+"Don't be easily discouraged," added Kennedy, as McNeill started down
+the hill to the garage. "If he is a fox he'll try to throw you off the
+trail. Hang on."
+
+"What was that for?" I asked as the detective disappeared. "Did you
+want to get rid of him?"
+
+"Partly," replied Craig, descending slowly, after a long survey of the
+surrounding country.
+
+We had reached the garage, deserted now except for our own car.
+
+"I'd like to investigate that tower," remarked Kennedy with a keen look
+at me, "if it could be done without seeming to violate Mr. Carter's
+hospitality."
+
+"Well," I observed, my eye catching a ladder beside the garage,
+"there's a ladder. We can do no more than try."
+
+He walked over to the automobile, took a little package out, slipped it
+into his pocket, and a few minutes later we had set the ladder up
+against the side of the boathouse farthest away from the house. It was
+the work of only a moment for Kennedy to scale it and prowl across the
+roof to the tower, while I stood guard at the foot.
+
+"No one has been up there recently," he panted breathlessly as he
+rejoined me. "There isn't a sign."
+
+We took the ladder quietly back to the garage, then Kennedy led the way
+down the shore to a sort of little summerhouse cut off from the
+boathouse and garage by the trees, though over the top of a hedge one
+could still see the boathouse tower.
+
+We sat down, and Craig filled his lungs with the good salt air,
+sweeping his eye about the blue and green panorama as though this were
+a holiday and not a mystery case.
+
+"Walter," he said at length, "I wish you'd take the car and go around
+to Verplanck's. I don't think you can see the tower through the trees,
+but I should like to be sure."
+
+I found that it could not be seen, though I tried all over the place
+and got myself disliked by the gardener and suspected by a watchman
+with a dog.
+
+It could not have been from the tower of the boathouse that we had seen
+the light, and I hurried back to Craig to tell him so. But when I
+returned, I found that he was impatiently pacing the little rustic
+summerhouse, no longer interested in what he had sent me to find out.
+
+"What has happened?" I asked eagerly.
+
+"Just come out here and I'll show you something," he replied, leaving
+the summerhouse and approaching the boathouse from the other side of
+the hedge, on the beach, so that the house itself cut us off from
+observation from Carter's.
+
+"I fixed a lens on the top of that tower when I was up there," he
+explained, pointing up at it. "It must be about fifty feet high. From
+there, you see, it throws a reflection down to this mirror. I did it
+because through a skylight in the tower I could read whatever was
+written by anyone sitting at Carter's desk in the corner under it."
+
+"Read?" I repeated, mystified.
+
+"Yes, by invisible light," he continued. "This invisible light
+business, you know, is pretty well understood by this time. I was only
+repeating what was suggested once by Professor Wood of Johns Hopkins.
+Practically all sources of light, you understand, give out more or less
+ultraviolet light, which plays no part in vision whatever. The human
+eye is sensitive to but few of the light rays that reach it, and if our
+eyes were constituted just the least bit differently we should have an
+entirely different set of images.
+
+"But by the use of various devices we can, as it were, translate these
+ultraviolet rays into terms of what the human eye can see. In order to
+do it, all the visible light rays which show us the thing as we see
+it--the tree green, the sky blue--must be cut off. So in taking an
+ultraviolet photograph a screen must be used which will be opaque to
+these visible rays and yet will let the ultraviolet rays through to
+form the image. That gave Professor Wood a lot of trouble. Glass won't
+do, for glass cuts off the ultraviolet rays entirely. Quartz is a very
+good medium, but it does not cut off all the visible light. In fact
+there is only one thing that will do the work, and that is metallic
+silver."
+
+I could not fathom what he was driving at, but the fascination of
+Kennedy himself was quite sufficient.
+
+"Silver," he went on, "is all right if the objects can be illuminated
+by an electric spark or some other source rich in the rays. But it
+isn't entirely satisfactory when sunlight is concerned, for various
+reasons that I need not bore you with. Professor Wood has worked out a
+process of depositing nickel on glass. That's it up there," he
+concluded, wheeling a lower reflector about until it caught the image
+of the afternoon sun thrown from the lens on the top of the tower.
+
+"You see," he resumed, "that upper lens is concave so that it enlarges
+tremendously. I can do some wonderful tricks with that."
+
+I had been lighting a cigarette and held a box of safety wind matches
+in my hand.
+
+"Give me that matchbox," he asked.
+
+He placed it at the foot of the tower. Then he went off, I should say,
+without exaggeration, a hundred feet.
+
+The lettering on the matchbox could be seen in the silvered mirror,
+enlarged to such a point that the letters were plainly visible!
+
+"Think of the possibilities in that," he added excitedly. "I saw them
+at once. You can read what some one is writing at a desk a hundred,
+perhaps two hundred feet away."
+
+"Yes," I cried, more interested in the practical aspects of it than in
+the mechanics and optics. "What have you found?"
+
+"Some one came into the boathouse while you were away," he said. "He
+had a note. It read, 'Those new detectives are watching everything. We
+must have the evidence. You must get those letters to-night, without
+fail.'"
+
+"Letters--evidence," I repeated. "Who wrote it? Who received it?"
+
+"I couldn't see over the hedge who had entered the boathouse, and by
+the time I got around here he was gone."
+
+"Was it Wickham--or intended for Wickham?" I asked.
+
+Kennedy shrugged his shoulders.
+
+"We'll gain nothing by staying here," he said. "There is just one
+possibility in the case, and I can guard against that only by returning
+to Verplanck's and getting some of that stuff I brought up here with
+me. Let us go."
+
+Late in the afternoon though it was, after our return, Kennedy insisted
+on hurrying from Verplanck's to the Yacht Club up the bay. It was a
+large building, extending out into the water on made land, from which
+ran a long, substantial dock. He had stopped long enough only to ask
+Verplanck to lend him the services of his best mechanician, a Frenchman
+named Armand.
+
+On the end of the yacht club dock Kennedy and Armand set up a large
+affair which looked like a mortar. I watched curiously, dividing my
+attention between them and the splendid view of the harbor which the
+end of the dock commanded on all sides.
+
+"What is this?" I asked finally. "Fireworks?"
+
+"A rocket mortar of light weight," explained Kennedy, then dropped into
+French as he explained to Armand the manipulation of the thing.
+
+There was a searchlight near by on the dock.
+
+"You can use that?" queried Kennedy.
+
+"Oh, yes. Mr. Verplanck, he is vice-commodore of the club. Oh, yes, I
+can use that. Why, Monsieur?"
+
+Kennedy had uncovered a round brass case. It did not seem to amount to
+much, as compared to some of the complicated apparatus he had used. In
+it was a four-sided prism of glass--I should have said, cut off the
+corner of a huge glass cube.
+
+He handed it to us.
+
+"Look in it," he said.
+
+It certainly was about the most curious piece of crystal gazing I had
+ever done. Turn the thing any way I pleased and I could see my face in
+it, just as in an ordinary mirror.
+
+"What do you call it?" Armand asked, much interested.
+
+"A triple mirror," replied Kennedy, and again, half in English and half
+in French, neither of which I could follow, he explained the use of the
+mirror to the mechanician.
+
+We were returning up the dock, leaving Armand with instructions to be
+at the club at dusk, when we met McNeill, tired and disgusted.
+
+"What luck?" asked Kennedy.
+
+"Nothing," he returned. "I had a 'short' shadow and a 'long' shadow at
+Wickham's heels all day. You know what I mean. Instead of one man,
+two--the second sleuthing in the other's tracks. If he escaped Number
+One, Number Two would take it up, and I was ready to move up into
+Number Two's place. They kept him in sight about all the time. Not a
+fact. But then, of course, we don't know what he was doing before we
+took up tailing him. Say," he added, "I have just got word from an
+agency with which I correspond in New York that it is reported that a
+yeggman named 'Australia Mac,' a very daring and clever chap, has been
+attempting to dispose of some of the goods which we know have been
+stolen through one of the worst 'fences' in New York."
+
+"Is that all?" asked Craig, with the mention of Australia Mac showing
+the first real interest yet in anything that McNeill had done since we
+met him the night before.
+
+"All so far. I wired for more details immediately."
+
+"Do you know anything about this Australia Mac?"
+
+"Not much. No one does. He's a new man, it seems, to the police here."
+
+"Be here at eight o'clock, McNeill," said Craig, as we left the club
+for Verplanck's. "If you can find out more about this yeggman, so much
+the better."
+
+"Have you made any progress?" asked Verplanck as we entered the estate
+a few minutes later.
+
+"Yes," returned Craig, telling only enough to whet his interest.
+"There's a clue, as I half expected, from New York, too. But we are so
+far away that we'll have to stick to my original plan. You can trust
+Armand?"
+
+"Absolutely."
+
+"Then we shall transfer our activity to the Yacht Club to-night," was
+all that Kennedy vouchsafed.
+
+
+
+
+CHAPTER VI
+
+THE TRIPLE MIRROR
+
+
+It was the regular Saturday night dance at the club, a brilliant
+spectacle, faces that radiated pleasure, gowns that for startling
+combinations of color would have shamed a Futurist, music that set the
+feet tapping irresistibly--a scene which I shall pass over because it
+really has no part in the story.
+
+The fascination of the ballroom was utterly lost on Craig. "Think of
+all the houses only half guarded about here to-night," he mused, as we
+joined Armand and McNeill on the end of the dock. I could not help
+noting that that was the only idea which the gay, variegated, sparkling
+tango throng conveyed to him.
+
+In front of the club was strung out a long line of cars, and at the
+dock several speed boats of national and international reputation,
+among them the famous Streamline II, at our instant beck and call. In
+it Craig had already placed some rather bulky pieces of apparatus, as
+well as a brass case containing a second triple mirror like that which
+he had left with Armand.
+
+With McNeill, I walked back along the pier, leaving Kennedy with
+Armand, until we came to the wide porch, where we joined the
+wallflowers and the rocking-chair fleet. Mrs. Verplanck, I observed,
+was a beautiful dancer. I picked her out in the throng immediately,
+dancing with Carter.
+
+McNeill tugged at my sleeve. Without a word I saw what he meant me to
+see. Verplanck and Mrs. Hollingsworth were dancing together. Just then,
+across the porch I caught sight of Kennedy at one of the wide windows.
+He was trying to attract Verplanck's attention, and as he did so I
+worked my way through the throng of chatting couples leaving the floor
+until I reached him. Verplanck, oblivious, finished the dance; then,
+seeming to recollect that he had something to attend to, caught sight
+of us, and ran off during the intermission from the gay crowd to which
+he resigned Mrs. Hollingsworth.
+
+"What is it?" he asked.
+
+"There's that light down the bay," whispered Kennedy.
+
+Instantly Verplanck forgot about the dance.
+
+"Where?" he asked.
+
+"In the same place."
+
+I had not noticed, but Mrs. Verplanck, woman-like, had been able to
+watch several things at once. She had seen us and had joined us.
+
+"Would you like to run down there in the Streamline?" he asked. "It
+will only take a few minutes."
+
+"Very much."
+
+"What is it--that light again?" she asked, as she joined us in walking
+down the dock.
+
+"Yes," answered her husband, pausing to look for a moment at the stuff
+Kennedy had left with Armand. Mrs. Verplanck leaned over the
+Streamline, turned as she saw me, and said: "I wish I could go with
+you. But evening dress is not the thing for a shivery night in a speed
+boat. I think I know as much about it as Mr. Verplanck. Are you going
+to leave Armand?"
+
+"Yes," replied Kennedy, taking his place beside Verplanck, who was
+seated at the steering wheel. "Walter and McNeill, if you two will sit
+back there, we're ready. All right."
+
+Armand had cast us off and Mrs. Verplanck waved from the end of the
+float as the Streamline quickly shot out into the night, a buzzing,
+throbbing shape of mahogany and brass, with her exhausts sticking out
+like funnels and booming like a pipe organ. It took her only seconds to
+eat into the miles.
+
+"A little more to port," said Kennedy, as Verplanck swung her around.
+
+Just then the steady droning of the engine seemed a bit less
+rhythmical. Verplanck throttled her down, but it had no effect. He shut
+her off. Something was wrong. As he crawled out into the space forward
+of us where the engine was, it seemed as if the Streamline had broken
+down suddenly and completely.
+
+Here we were floundering around in the middle of the bay.
+
+"Chuck-chuck-chuck," came in quick staccato out of the night. It was
+Montgomery Carter, alone, on his way across the bay from the club, in
+his own boat.
+
+"Hello--Carter," called Verplanck.
+
+"Hello, Verplanck. What's the matter?"
+
+"Don't know. Engine trouble of some kind. Can you give us a line?"
+
+"I've got to go down to the house," he said, ranging up near us. "Then
+I can take you back. Perhaps I'd better get you out of the way of any
+other boats first. You don't mind going over and then back?"
+
+Verplanck looked at Craig. "On the contrary," muttered Craig, as he
+made fast the welcome line.
+
+The Carter dock was some three miles from the club on the other side of
+the bay. As we came up to it, Carter shut off his engine, bent over it
+a moment, made fast, and left us with a hurried, "Wait here."
+
+Suddenly, overhead, we heard a peculiar whirring noise that seemed to
+vibrate through the air. Something huge, black, monster-like, slid down
+a board runway into the water, traveled a few feet, in white suds and
+spray, rose in the darkness--and was gone!
+
+As the thing disappeared, I thought I could hear a mocking laugh flung
+back at us.
+
+"What is it?" I asked, straining my eyes at what had seemed for an
+instant like a great flying fish with finny tail and huge fins at the
+sides and above.
+
+"'Aquaero,'" quoted Kennedy quickly. "Don't you understand--a
+hydroaeroplane--a flying boat. There are hundreds of privately owned
+flying boats now wherever there is navigable water. That was the secret
+of Carter's boathouse, of the light we saw in the air."
+
+"But this Aquaero--who is he?" persisted McNeill.
+"Carter--Wickham--Australia Mac?"
+
+We looked at each other blankly. No one said a word. We were captured,
+just as effectively as if we were ironed in a dungeon. There were the
+black water, the distant lights, which at any other time I should have
+said would have been beautiful.
+
+Kennedy had sprung into Carter's boat.
+
+"The deuce," he exclaimed. "He's put her out of business."
+
+Verplanck, chagrined, had been going over his own engine feverishly.
+"Do you see that?" he asked suddenly, holding up in the light of a
+lantern a little nut which he had picked out of the complicated
+machinery. "It never belonged to this engine. Some one placed it there,
+knowing it would work its way into a vital part with the vibration."
+
+Who was the person, the only one who could have done it? The answer was
+on my lips, but I repressed it. Mrs. Verplanck herself had been bending
+over the engine when last I saw her. All at once it flashed over me
+that she knew more about the phantom bandit than she had admitted. Yet
+what possible object could she have had in putting the Streamline out
+of commission?
+
+My mind was working rapidly, piecing together the fragmentary facts.
+The remark of Kennedy, long before, instantly assumed new significance.
+What were the possibilities of blackmail in the right sort of evidence?
+The yeggman had been after what was more valuable than jewels--letters!
+Whose? Suddenly I saw the situation. Carter had not been robbed at all.
+He was in league with the robber. That much was a blind to divert
+suspicion. He was a lawyer--some one's lawyer. I recalled the message
+about letters and evidence, and as I did so there came to mind a
+picture of Carter and the woman he had been dancing with. In return for
+his inside information about the jewels of the wealthy homes of
+Bluffwood, the yeggman was to get something of interest and importance
+to his client.
+
+The situation called for instant action. Yet what could we do, marooned
+on the other side of the bay?
+
+From the Club dock a long finger of light swept out into the night,
+plainly enough near the dock, but diffused and disclosing nothing in
+the distance. Armand had trained it down the bay in the direction we
+had taken, but by the time the beam reached us it was so weak that it
+was lost.
+
+Craig had leaped up on the Carter dock and was capping and uncapping
+with the brass cover the package which contained the triple mirror.
+
+Still in the distance I could see the wide path of light, aimed toward
+us, but of no avail.
+
+"What are you doing?" I asked.
+
+"Using the triple mirror to signal to Armand. It is something better
+than wireless. Wireless requires heavy and complicated apparatus. This
+is portable, heatless, almost weightless, a source of light depending
+for its power on another source of light at a great distance."
+
+I wondered how Armand could ever detect its feeble ray.
+
+"Even in the case of a rolling ship," Kennedy continued, alternately
+covering and uncovering the mirror, "the beam of light which this
+mirror reflects always goes back, unerring, to its source. It would do
+so from an aeroplane, so high in the air that it could not be located.
+The returning beam is invisible to anyone not immediately in the path
+of the ray, and the ray always goes to the observer. It is simply a
+matter of pure mathematics practically applied. The angle of incidence
+equals the angle of reflection. There is not a variation of a foot in
+two miles."
+
+"What message are you sending him?" asked Verplanck.
+
+"To tell Mrs. Hollingsworth to hurry home immediately," Kennedy
+replied, still flashing the letters according to his code.
+
+"Mrs. Hollingsworth?" repeated Verplanck, looking up.
+
+"Yes. This hydroaeroplane yeggman is after something besides jewels
+to-night. Were those letters that were stolen from you the only ones
+you had in the safe?"
+
+Verplanck looked up quickly. "Yes, yes. Of course."
+
+"You had none from a woman--"
+
+"No," he almost shouted. Of a sudden it seemed to dawn on him what
+Kennedy was driving at--the robbery of his own house with no loss
+except of a packet of letters on business, followed by the attempt on
+Mrs. Hollingsworth. "Do you think I'd keep dynamite, even in the safe?"
+
+To hide his confusion he had turned and was bending again over the
+engine.
+
+"How is it?" asked Kennedy, his signaling over.
+
+"Able to run on four cylinders and one propeller," replied Verplanck.
+
+"Then let's try her. Watch the engine. I'll take the wheel."
+
+Limping along, the engine skipping and missing, the once peerless
+Streamline started back across the bay. Instead of heading toward the
+club, Kennedy pointed her bow somewhere between that and Verplanck's.
+
+"I wish Armand would get busy," he remarked, after glancing now and
+then in the direction of the club. "What can be the matter?"
+
+"What do you mean?" I asked.
+
+There came the boom as if of a gun far away in the direction in which
+he was looking, then another.
+
+"Oh, there it is. Good fellow. I suppose he had to deliver my message
+to Mrs. Hollingsworth himself first."
+
+From every quarter showed huge balls of fire, rising from the sea, as
+it were, with a brilliantly luminous flame.
+
+"What is it?" I asked, somewhat startled.
+
+"A German invention for use at night against torpedo and aeroplane
+attacks. From that mortar Armand has shot half a dozen bombs of
+phosphide of calcium which are hurled far into the darkness. They are
+so constructed that they float after a short plunge and are ignited on
+contact by the action of the salt water itself."
+
+It was a beautiful pyrotechnic display, lighting up the shore and hills
+of the bay as if by an unearthly flare.
+
+"There's that thing now!" exclaimed Kennedy.
+
+In the glow we could see a peculiar, birdlike figure flying through the
+air over toward the Hollingsworth house. It was the hydroaeroplane.
+
+Out from the little stretch of lawn under the accentuated shadow of the
+trees, she streaked into the air, swaying from side to side as the
+pilot operated the stabilizers on the ends of the planes to counteract
+the puffs of wind off the land.
+
+How could she ever be stopped?
+
+The Streamline, halting and limping, though she was, had almost crossed
+the bay before the light bombs had been fired by Armand. Every moment
+brought the flying boat nearer.
+
+She swerved. Evidently the pilot had seen us at last and realized who
+we were. I was so engrossed watching the thing that I had not noticed
+that Kennedy had given the wheel to Verplanck and was standing in the
+bow, endeavoring to sight what looked like a huge gun.
+
+In rapid succession half a dozen shots rang out. I fancied I could
+almost hear the ripping and tearing of the tough rubber-coated silken
+wings of the hydroaeroplane as the wind widened the perforation the gun
+had made.
+
+She had not been flying high, but now she swooped down almost like a
+gull, seeking to rest on the water. We were headed toward her now, and
+as the flying boat sank I saw one of the passengers rise in his seat,
+swing his arm, and far out something splashed in the bay.
+
+On the water, with wings helpless, the flying boat was no match for the
+Streamline now. She struck at an acute angle, rebounded in the air for
+a moment, and with a hiss skittered along over the waves, planing with
+the help of her exhaust under the step of the boat.
+
+There she was, a hull, narrow, scow-bowed, like a hydroplane, with a
+long pointed stern and a cockpit for two men, near the bow. There were
+two wide, winglike planes, on a light latticework of wood covered with
+silk, trussed and wired like a kite frame, the upper plane about five
+feet above the lower, which was level with the boat deck. We could see
+the eight-cylindered engine which drove a two-bladed wooden propeller,
+and over the stern were the air rudder and the horizontal planes. There
+she was, the hobbled steed now of the phantom bandit who had
+accomplished the seemingly impossible.
+
+In spite of everything, however, the flying boat reached the shore a
+trifle ahead of us. As she did so both figures in her jumped, and one
+disappeared quickly up the bank, leaving the other alone.
+
+"Verplanck, McNeill--get him," cried Kennedy, as our own boat grated on
+the beach. "Come, Walter, we'll take the other one."
+
+The man had seen that there was no safety in flight. Down the shore he
+stood, without a hat, his hair blown pompadour by the wind.
+
+As we approached Carter turned superciliously, unbuttoning his bulky
+khaki life preserver jacket.
+
+"Well?" he asked coolly.
+
+Not for a moment did Kennedy allow the assumed coolness to take him
+back, knowing that Carter's delay did not cover the retreat of the
+other man.
+
+"So," Craig exclaimed, "you are the--the air pirate?"
+
+Carter disdained to reply.
+
+"It was you who suggested the millionaire households, full of jewels,
+silver and gold, only half guarded; you, who knew the habits of the
+people; you, who traded that information in return for another piece of
+thievery by your partner, Australia Mac--Wickham he called himself here
+in Bluffwood. It was you---"
+
+A car drove up hastily, and I noted that we were still on the
+Hollingsworth estate. Mrs. Hollingsworth had seen us and had driven
+over toward us.
+
+"Montgomery!" she cried, startled.
+
+"Yes," said Kennedy quickly, "air pirate and lawyer for Mrs. Verplanck
+in the suit which she contemplated bringing--"
+
+Mrs. Hollingsworth grew pale under the ghastly, flickering light from
+the bay.
+
+"Oh!" she cried, realizing at what Kennedy hinted, "the letters!"
+
+"At the bottom of the harbor, now," said Kennedy. "Mr. Verplanck tells
+me he has destroyed his. The past is blotted out as far as that is
+concerned. The future is--for you three to determine. For the present
+I've caught a yeggman and a blackmailer."
+
+
+
+
+CHAPTER VII
+
+THE WIRELESS WIRETAPPERS
+
+
+Kennedy did not wait at Bluffwood longer than was necessary. It was
+easy enough now to silence Montgomery Carter, and the reconciliation of
+the Verplancks was assured. In the Star I made the case appear at the
+time to involve merely the capture of Australia Mac.
+
+When I dropped into the office the next day as usual, I found that I
+had another assignment that would take me out on Long Island. The story
+looked promising and I was rather pleased to get it.
+
+"Bound for Seaville, I'll wager," sounded a familiar voice in my ear,
+as I hurried up to the train entrance at the Long Island corner of the
+Pennsylvania Station.
+
+I turned quickly, to find Kennedy just behind me, breathless and
+perspiring.
+
+"Er--yes," I stammered in surprise at seeing him so unexpectedly, "but
+where did you come from? How did you know?"
+
+"Let me introduce Mr. Jack Waldon," he went on, as we edged our way
+toward the gate, "the brother of Mrs. Tracy Edwards, who disappeared so
+strangely from the houseboat Lucie last night at Seaville. That is the
+case you're going to write up, isn't it?"
+
+It was then for the first time that I noticed the excited young man
+beside Kennedy was really his companion.
+
+I shook hands with Waldon, who gave me a grip that was both a greeting
+and an added impulse in our general direction through the wicket.
+
+"Might have known the Star would assign you to this Edwards case,"
+panted Kennedy, mopping his forehead, for the heat in the terminal was
+oppressive and the crowd, though not large, was closely packed. "Mr.
+Jameson is my right-hand man," he explained to Waldon, taking us each
+by the arm and urging us forward. "Waldon was afraid we might miss the
+train or I should have tried to get you, Walter, at the office."
+
+It was all done so suddenly that they quite took away what remaining
+breath I had, as we settled ourselves to swelter in the smoker instead
+of in the concourse. I did not even protest at the matter-of-fact
+assurance with which Craig assumed that his deduction as to my
+destination was correct.
+
+Waldon, a handsome young fellow in a flannel suit and yachting cap
+somewhat the worse for his evidently perturbed state of mind, seemed to
+eye me for the moment doubtfully, in spite of Kennedy's cordial
+greeting.
+
+"I've had all the first editions of the evening papers," I hinted as we
+sped through the tunnel, "but the stories seemed to be quite the
+same--pretty meager in details."
+
+"Yes," returned Waldon with a glance at Kennedy, "I tried to keep as
+much out of the papers as I could just now for Lucie's sake."
+
+"You needn't fear Jameson," remarked Kennedy.
+
+He fumbled in his pocket, then paused a moment and shot a glance of
+inquiry at Waldon, who nodded a mute acquiescence to him.
+
+"There seem to have been a number of very peculiar disappearances
+lately," resumed Kennedy, "but this case of Mrs. Edwards is by far the
+most extraordinary. Of course the Star hasn't had that--yet," he
+concluded, handing me a sheet of notepaper.
+
+"Mr. Waldon didn't give it out, hoping to avoid scandal."
+
+I took the paper and read eagerly, in a woman's hand:
+
+"MY DEAR MISS FOX: I have been down here at Seaville on our houseboat,
+the Lucie, for several days for a purpose which now is accomplished.
+
+"Already I had my suspicions of you, from a source which I need not
+name. Therefore, when the Kronprinz got into wireless communication
+with the station at Seaville I determined through our own wireless on
+the Lucie to overhear whether there would be any exchange of messages
+between my husband and yourself.
+
+"I was able to overhear the whole thing and I want you to know that
+your secret is no longer a secret from me, and that I have already told
+Mr. Edwards that I know it. You ruin his life by your intimacy which
+you seem to want to keep up, although you know you have no right to do
+it, but you shall not ruin mine.
+
+"I am thoroughly disillusioned now. I have not decided on what steps to
+take, but--"
+
+Only a casual glance was necessary to show me that the writing seemed
+to grow more and more weak as it progressed, and the note stopped
+abruptly, as if the writer had been suddenly interrupted or some new
+idea had occurred to her.
+
+Hastily I tried to figure it out. Lucie Waldon, as everybody knew, was
+a famous beauty, a marvel of charm and daintiness, slender, with big,
+soulful, wistful eyes. Her marriage to Tracy Edwards, the wealthy
+plunger and stockbroker, had been a great social event the year before,
+and it was reputed at the time that Edwards had showered her with
+jewels and dresses to the wonder and talk even of society.
+
+As for Valerie Fox, I knew she had won quick recognition and even fame
+as a dancer in New York during the previous winter, and I recalled
+reading three or four days before that she had just returned on the
+Kronprinz from a trip abroad.
+
+"I don't suppose you have had time to see Miss Fox," I remarked. "Where
+is she?"
+
+"At Beach Park now, I think," replied Waldon, "a resort a few miles
+nearer the city on the south shore, where there is a large colony of
+actors."
+
+I handed back the letter to Kennedy.
+
+"What do you make of it?" he asked, as he folded it up and put it back
+into his pocket.
+
+"I hardly know what to say," I replied. "Of course there have been
+rumors, I believe, that all was not exactly like a honeymoon still with
+the Tracy Edwardses."
+
+"Yes," returned Waldon slowly, "I know myself that there has been some
+trouble, but nothing definite until I found this letter last night in
+my sister's room. She never said anything about it either to mother or
+myself. They haven't been much together during the summer, and last
+night when she disappeared Tracy was in the city. But I hadn't thought
+much about it before, for, of course, you know he has large financial
+interests that make him keep in pretty close touch with New York and
+this summer hasn't been a particularly good one on the stock exchange."
+
+"And," I put in, "a plunger doesn't always make the best of husbands.
+Perhaps there is temperament to be reckoned with here."
+
+"There seem to be a good many things to be reckoned with," Craig
+considered. "For example, here's a houseboat, the Lucie, a palatial
+affair, cruising about aimlessly, with a beautiful woman on it. She
+gives a little party, in the absence of her husband, to her brother,
+his fiancee and her mother, who visit her from his yacht, the Nautilus.
+They break up, those living on the Lucie going to their rooms and the
+rest back to the yacht, which is anchored out further in the deeper
+water of the bay.
+
+"Some time in the middle of the night her maid, Juanita, finds that she
+is not in her room. Her brother is summoned back from his yacht and
+finds that she has left this pathetic, unfinished letter. But otherwise
+there is no trace of her. Her husband is notified and hurries out
+there, but he can find no clue. Meanwhile, Mr. Waldon, in despair,
+hurries down to the city to engage me quietly."
+
+"You remember I told you," suggested Waldon, "that my sister hadn't
+been feeling well for several days. In fact it seemed that the sea air
+wasn't doing her much good, and some one last night suggested that she
+try the mountains."
+
+"Had there been anything that would foreshadow the--er--disappearance?"
+asked Kennedy.
+
+"Only as I say, that for two or three days she seemed to be listless,
+to be sinking by slow and easy stages into a sort of vacant, moody
+state of ill health."
+
+"She had a doctor, I suppose?" I asked.
+
+"Yes, Dr. Jermyn, Tracy's own personal physician came down from the
+city several days ago."
+
+"What did he say?"
+
+"He simply said that it was congestion of the lungs. As far as he could
+see there was no apparent cause for it. I don't think he was very
+enthusiastic about the mountain air idea. The fact is he was like a
+good many doctors under the circumstances, noncommittal--wanted her
+under observation, and all that sort of thing."
+
+"What's your opinion?" I pressed Craig. "Do you think she has run away?"
+
+"Naturally, I'd rather not attempt to say yet," Craig replied
+cautiously. "But there are several possibilities. Yes, she might have
+left the houseboat in some other boat, of course. Then there is the
+possibility of accident. It was a hot night. She might have been
+leaning from the window and have lost her balance. I have even thought
+of drugs, that she might have taken something in her despondency and
+have fallen overboard while under the influence of it. Then, of course,
+there are the two deductions that everyone has made already--either
+suicide or murder."
+
+Waldon had evidently been turning something over in his mind.
+
+"There was a wireless outfit aboard the houseboat," he ventured at
+length.
+
+"What of that?" I asked, wondering why he was changing the subject so
+abruptly.
+
+"Why, only this," he replied. "I have been reading about wireless a
+good deal lately, and if the theories of some scientists are correct,
+the wireless age is not without its dangers as well as its wonders. I
+recall reading not long ago of a German professor who says there is no
+essential difference between wireless waves and the X-rays, and we know
+the terrible physical effects of X-rays. I believe he estimated that
+only one three hundred millionth part of the electrical energy
+generated by sending a message from one station to another near by is
+actually used up in transmitting the message. The rest is dispersed in
+the atmosphere. There must be a good deal of such stray electrical
+energy about Seaville. Isn't it possible that it might hit some one
+somewhere who was susceptible?"
+
+Kennedy said nothing. Waldon's was at least a novel idea, whether it
+was plausible or not. The only way to test it out, as far as I could
+determine, was to see whether it fitted with the facts after a careful
+investigation of the case itself.
+
+It was still early in the day and the trains were not as crowded as
+they would be later. Consequently our journey was comfortable enough
+and we found ourselves at last at the little vine-covered station at
+Seaville.
+
+One could almost feel that the gay summer colony was in a state of
+subdued excitement. As we left the quaint station and walked down the
+main street to the town wharf where we expected some one would be
+waiting for us, it seemed as if the mysterious disappearance of the
+beautiful Mrs. Edwards had put a damper on the life of the place. In
+the hotels there were knots of people evidently discussing the affair,
+for as we passed we could tell by their faces that they recognized us.
+One or two bowed and would have joined us, if Waldon had given any
+encouragement. But he did not stop, and we kept on down the street
+quickly.
+
+I myself began to feel the spell of mystery about the case as I had not
+felt it among the distractions of the city. Perhaps I imagined it, but
+there even seemed to be something strange about the houseboat which we
+could descry at anchor far down the bay as we approached the wharf.
+
+We were met, as Waldon had arranged, by a high-powered runabout, the
+tender to his own yacht, a slim little craft of mahogany and brass,
+driven like an automobile, and capable of perhaps twenty-five or thirty
+miles an hour. We jumped in and were soon skimming over the waters of
+the bay like a skipping stone.
+
+It was evident that Waldon was much relieved at having been able to
+bring assistance, in which he had as much confidence as he reposed in
+Kennedy. At any rate it was something to be nearing the scene of action
+again.
+
+The Lucie was perhaps seventy feet long and a most attractive craft,
+with a hull yachty in appearance and of a type which could safely make
+long runs along the coast, a stanch, seaworthy boat, of course without
+the speed of the regularly designed yacht, but more than making up in
+comfort for those on board what was lost in that way. Waldon pointed
+out with obvious pride his own trim yacht swinging gracefully at anchor
+a half mile or so away.
+
+As we approached the houseboat I looked her over carefully. One of the
+first things I noticed was that there rose from the roof the primitive
+inverted V aerial of a wireless telegraph. I thought immediately of the
+unfinished letter and its contents, and shaded my eyes as I took a good
+look at the powerful transatlantic station on the spit of sand perhaps
+three or four miles distant, with its tall steel masts of the latest
+inverted L type and the cluster of little houses below, in which the
+operators and the plant were.
+
+Waldon noticed what I was looking at, and remarked, "It's a wonderful
+station--and well worth a visit, if you have the time--one of the most
+powerful on the coast, I understand."
+
+"How did the Lucie come to be equipped with wireless?" asked Craig
+quickly. "It's a little unusual for a private boat."
+
+"Mr. Edwards had it done when she was built," explained Waldon. "His
+idea was to use it to keep in touch with the stock market on trips."
+
+"And it has proved effective?" asked Craig.
+
+"Oh, yes--that is, it was all right last winter when he went on a short
+cruise down in Florida. This summer he hasn't been on the boat long
+enough to use it much."
+
+"Who operates it?"
+
+"He used to hire a licensed operator, although I believe the engineer,
+Pedersen, understands the thing pretty well and could use it if
+necessary."
+
+"Do you think it was Pedersen who used it for Mrs. Edwards?" asked
+Kennedy.
+
+"I really don't know," confessed Waldon. "Pedersen denies absolutely
+that he has touched the thing for weeks. I want you to quiz him. I
+wasn't able to get him to admit a thing."
+
+
+
+
+CHAPTER VIII
+
+THE HOUSEBOAT MYSTERY
+
+
+We had by this time swung around to the side of the houseboat. I
+realized as we mounted the ladder that the marine gasoline engine had
+materially changed the old-time houseboat from a mere scow or barge
+with a low flat house on it, moored in a bay or river, and only with
+difficulty and expense towed from one place to another. Now the
+houseboat was really a fair-sized yacht.
+
+The Lucie was built high in order to give plenty of accommodation for
+the living quarters. The staterooms, dining rooms and saloon were
+really rooms, with seven or eight feet of head room, and furnished just
+as one would find in a tasteful and expensive house.
+
+Down in the hull, of course, was the gasoline motor which drove the
+propeller, so that when the owner wanted a change of scene all that was
+necessary was to get up anchor, start the motor and navigate the
+yacht-houseboat to some other harbor.
+
+Edwards himself met us on the deck. He was a tall man, with a red face,
+a man of action, of outdoor life, apparently a hard worker and a hard
+player. It was quite evident that he had been waiting for the return of
+Waldon anxiously.
+
+"You find us considerably upset, Professor Kennedy," he greeted Craig,
+as his brother-in-law introduced us.
+
+Edwards turned and led the way toward the saloon. As he entered and
+bade us be seated in the costly cushioned wicker chairs I noticed how
+sumptuously it was furnished, and particularly its mechanical piano,
+its phonograph and the splendid hardwood floor which seemed to invite
+one to dance in the cool breeze that floated across from one set of
+open windows to the other. And yet in spite of everything, there was
+that indefinable air of something lacking, as in a house from which the
+woman is gone.
+
+"You were not here last night, I understand," remarked Kennedy, taking
+in the room at a glance.
+
+"Unfortunately, no," replied Edwards, "Business has kept me with my
+nose pretty close to the grindstone this summer. Waldon called me up in
+the middle of the night, however, and I started down in my car, which
+enabled me to get here before the first train. I haven't been able to
+do a thing since I got here except just wait--wait--wait. I confess
+that I don't know what else to do. Waldon seemed to think we ought to
+have some one down here--and I guess he was right. Anyhow, I'm glad to
+see you."
+
+I watched Edwards keenly. For the first time I realized that I had
+neglected to ask Waldon whether he had seen the unfinished letter. The
+question was unnecessary. It was evident that he had not.
+
+"Let me see, Waldon, if I've got this thing straight," Edwards went on,
+pacing restlessly up and down the saloon. "Correct me if I haven't.
+Last night, as I understand it, there was a sort of little family party
+here, you and Miss Verrall and your mother from the Nautilus, and Mrs.
+Edwards and Dr. Jermyn."
+
+"Yes," replied Waldon with, I thought, a touch of defiance at the words
+"family party." He paused as if he would have added that the Nautilus
+would have been more congenial, anyhow, then added, "We danced a little
+bit, all except Lucie. She said she wasn't feeling any too well."
+
+Edwards had paused by the door. "If you'll excuse me a minute," he
+said, "I'll call Jermyn and Mrs. Edwards' maid, Juanita. You ought to
+go over the whole thing immediately, Professor Kennedy."
+
+"Why didn't you say anything about the letter to him?" asked Kennedy
+under his breath.
+
+"What was the use?" returned Waldon. "I didn't know how he'd take it.
+Besides, I wanted your advice on the whole thing. Do you want to show
+it to him?"
+
+"Perhaps it's just as well," ruminated Kennedy. "It may be possible to
+clear the thing up without involving anybody's name. At any rate, some
+one is coming down the passage this way."
+
+Edwards entered with Dr. Jermyn, a clean-shaven man, youthful in
+appearance, yet approaching middle age. I had heard of him before. He
+had studied several years abroad and had gained considerable reputation
+since his return to America.
+
+Dr. Jermyn shook hands with us cordially enough, made some passing
+comment on the tragedy, and stood evidently waiting for us to disclose
+our hands.
+
+"You have been Mrs. Edwards' physician for some time, I believe?"
+queried Kennedy, fencing for an opening.
+
+"Only since her marriage," replied the doctor briefly.
+
+"She hadn't been feeling well for several days, had she?" ventured
+Kennedy again.
+
+"No," replied Dr. Jermyn quickly. "I doubt whether I can add much to
+what you already know. I suppose Mr. Waldon has told you about her
+illness. The fact is, I suppose her maid Juanita will be able to tell
+you really more than I can."
+
+I could not help feeling that Dr. Jermyn showed a great deal of
+reluctance in talking.
+
+"You have been with her several days, though, haven't you?"
+
+"Four days, I think. She was complaining of feeling nervous and
+telegraphed me to come down here. I came prepared to stay over night,
+but Mr. Edwards happened to run down that day, too, and he asked me if
+I wouldn't remain longer. My practice in the summer is such that I can
+easily leave it with my assistant in the city, so I agreed. Really,
+that is about all I can say. I don't know yet what was the matter with
+Mrs. Edwards, aside from the nervousness which seemed to be of some
+time standing."
+
+He stood facing us, thoughtfully stroking his chin, as a very pretty
+and petite maid nervously entered and stood facing us in the doorway.
+
+"Come in, Juanita," encouraged Edwards. "I want you to tell these
+gentlemen just what you told me about discovering that Madame had
+gone--and anything else that you may recall now."
+
+"It was Juanita who discovered that Madame was gone, you know," put in
+Waldon.
+
+"How did you discover it?" prompted Craig.
+
+"It was very hot," replied the maid, "and often on hot nights I would
+come in and fan Madame since she was so wakeful. Last night I went to
+the door and knocked. There was no reply. I called to her, 'Madame,
+madame.' Still there was no answer. The worst I supposed was that she
+had fainted. I continued to call."
+
+"The door was locked?" inquired Kennedy.
+
+"Yes, sir. My call aroused the others on the boat. Dr. Jermyn came and
+he broke open the door with his shoulder. But the room was empty.
+Madame was gone."
+
+"How about the windows?" asked Kennedy.
+
+"Open. They were always open these nights. Sometimes Madame would sit
+by the window when there was not much breeze."
+
+"I should like to see the room," remarked Craig, with an inquiring
+glance at Edwards.
+
+"Certainly," he answered, leading the way down a corridor.
+
+Mrs. Edwards' room was on the starboard side, with wide windows instead
+of portholes. It was furnished magnificently and there was little about
+it that suggested the nautical, except the view from the window.
+
+"The bed had not been slept in," Edwards remarked as we looked about
+curiously.
+
+Kennedy walked over quickly to the wide series of windows before which
+was a leather-cushioned window seat almost level with the window,
+several feet above the level of the water. It was by this window,
+evidently, that Juanita meant that Mrs. Edwards often sat. It was a
+delightful position, but I could readily see that it would be
+comparatively easy for anyone accidentally or purposely to fall.
+
+"I think myself," Waldon remarked to Kennedy, "that it must have been
+from the open window that she made her way to the outside. It seems
+that all agree that the door was locked, while the window was wide
+open."
+
+"There had been no sound--no cry to alarm you?" shot out Kennedy
+suddenly to Juanita.
+
+"No, sir, nothing. I could not sleep myself, and I thought of Madame."
+
+"You heard nothing?" he asked of Dr. Jermyn.
+
+"Nothing until I heard the maid call," he replied briefly.
+
+Mentally I ran over again Kennedy's first list of possibilities--taken
+off by another boat, accident, drugs, suicide, murder.
+
+Was there, I asked myself, sufficient reason for suicide? The letter
+seemed to me to show too proud a spirit for that. In fact the last
+sentence seemed to show that she was contemplating the surest method of
+revenge, rather than surrender. As for accident, why should a person
+fall overboard from a large houseboat into a perfectly calm harbor?
+Then, too, there had been no outcry. Somehow, I could not seem to fit
+any of the theories in with the facts. Evidently it was like many
+another case, one in which we, as yet, had insufficient data for a
+conclusion.
+
+Suddenly I recalled the theory that Waldon himself had advanced
+regarding the wireless, either from the boat itself or from the
+wireless station. For the moment, at least, it seemed plausible that
+she might have been seated at the window, that she might have been
+affected by escaped wireless, or by electrolysis. I knew that some
+physicians had described a disease which they attributed to wireless, a
+sort of anemia with a marked diminution in the number of red corpuscles
+in the blood, due partly to the over etherization of the air by reason
+of the alternating currents used to generate the waves.
+
+"I should like now to inspect the little wireless plant you have here
+on the Lucie," remarked Kennedy. "I noticed the mast as we were
+approaching a few minutes ago."
+
+I had turned at the sound of his voice in time to catch Edwards and Dr.
+Jermyn eyeing each other furtively. Did they know about the letter,
+after all, I wondered? Was each in doubt about just how much the other
+knew?
+
+There was no time to pursue these speculations. "Certainly," agreed Mr.
+Edwards promptly, leading the way.
+
+Kennedy seemed keenly interested in inspecting the little wireless
+plant, which was of a curious type and not exactly like any that I had
+seen before.
+
+"Wireless apparatus," he remarked, as he looked it over, "is divided
+into three parts, the source of power whether battery or dynamo, the
+making and sending of wireless waves, including the key, spark,
+condenser and tuning coil, and the receiving apparatus, head
+telephones, antennae, ground and detector."
+
+Pedersen, the engineer, came in while we were looking the plant over,
+but seemed uncommunicative to all Kennedy's efforts to engage him in
+conversation.
+
+"I see," remarked Kennedy, "that it is a very compact system with
+facilities for a quick change from one wave length to another."
+
+"Yes," grunted Pedersen, as averse to talking, evidently, as others on
+the Lucie.
+
+"Spark gap, quenched type," I heard Kennedy mutter almost to himself,
+with a view to showing Pedersen that he knew something about it. "Break
+system relay--operator can overhear any interference while
+transmitting--transformation by a single throw of a six-point switch
+which tunes the oscillating and open circuits to resonance. Very
+clever--very efficient. By the way, Pedersen, are you the only person
+aboard who can operate this?"
+
+"How should I know?" he answered almost surlily.
+
+"You ought to know, if anybody," answered Kennedy unruffled. "I know
+that it has been operated within the past few days."
+
+Pedersen shrugged his shoulders. "You might ask the others aboard," was
+all he said. "Mr. Edwards pays me to operate it only for himself, when
+he has no other operator."
+
+Kennedy did not pursue the subject, evidently from fear of saying too
+much just at present.
+
+"I wonder if there is anyone else who could have operated it," said
+Waldon, as we mounted again to the deck.
+
+"I don't know," replied Kennedy, pausing on the way up. "You haven't a
+wireless on the Nautilus, have you?"
+
+Waldon shook his head. "Never had any particular use for it myself," he
+answered.
+
+"You say that Miss Verrall and her mother have gone back to the city?"
+pursued Kennedy, taking care that as before the others were out of
+earshot.
+
+"Yes."
+
+"I'd like to stay with you tonight, then," decided Kennedy. "Might we
+go over with you now? There doesn't seem to be anything more I can do
+here, unless we get some news about Mrs. Edwards."
+
+Waldon seemed only too glad to agree, and no one on the Lucie insisted
+on our staying.
+
+We arrived at the Nautilus a few minutes later, and while we were
+lunching Kennedy dispatched the tender to the Marconi station with a
+note.
+
+It was early in the afternoon when the tender returned with several
+packages and coils of wire. Kennedy immediately set to work on the
+Nautilus stretching out some of the wire.
+
+"What is it you are planning?" asked Waldon, to whom every action of
+Kennedy seemed to be a mystery of the highest interest.
+
+"Improvising my own wireless," he replied, not averse to talking to the
+young man to whom he seemed to have taken a fancy. "For short
+distances, you know, it isn't necessary to construct an aerial pole or
+even to use outside wires to receive messages. All that is needed is to
+use just a few wires stretched inside a room. The rest is just the
+apparatus."
+
+I was quite as much interested as Waldon. "In wireless," he went on,
+"the signals are not sent in one direction, but in all, so that a
+person within range of the ethereal disturbance can get them if only he
+has the necessary receiving apparatus. This apparatus need not be so
+elaborate and expensive as used to be thought needful if a sensitive
+detector is employed, and I have sent over to the station for a new
+piece of apparatus which I knew they had in almost any Marconi station.
+Why, I've got wireless signals using only twelve feet of number
+eighteen copper wire stretched across a room and grounded with a water
+pipe. You might even use a wire mattress on an iron bedstead."
+
+"Can't they find out by--er, interference?" I asked, repeating the term
+I had so often heard.
+
+Kennedy laughed. "No, not for radio apparatus which merely receives
+radiograms and is not equipped for sending. I am setting up only one
+side of a wireless outfit here. All I want to do is to hear what is
+being said. I don't care about saying anything."
+
+He unwrapped another package which had been loaned to him by the radio
+station and we watched him curiously as he tested it and set it up.
+Some parts of it I recognized such as the very sensitive microphone,
+and another part I could have sworn was a phonograph cylinder, though
+Craig was so busy testing his apparatus that now we could not ask
+questions.
+
+It was late in the afternoon when he finished, and we had just time to
+run up to the dock at Seaville and stop off at the Lucie to see if
+anything had happened in the intervening hours before dinner. There was
+nothing, except that I found time to file a message to the Star and
+meet several fellow newspaper men who had been sent down by other
+papers on the chance of picking up a good story.
+
+We had the Nautilus to ourselves, and as she was a very comfortable
+little craft, we really had a very congenial time, a plunge over her
+side, a good dinner, and then a long talk out on deck under the stars,
+in which we went over every phase of the case. As we discussed it,
+Waldon followed keenly, and it was quite evident from his remarks that
+he had come to the conclusion that Dr. Jermyn at least knew more than
+he had told about the case.
+
+Still, the day wore away with no solution yet of the mystery.
+
+
+
+
+CHAPTER IX
+
+THE RADIO DETECTIVE
+
+
+It was early the following morning when a launch drew up beside the
+Nautilus. In it were Edwards and Dr. Jermyn, wildly excited.
+
+"What's the matter?" called out Waldon.
+
+"They--they have found the body," Edwards blurted out.
+
+Waldon paled and clutched the rail. He had thought the world of his
+sister, and not until the last moment had he given up hope that perhaps
+she might be found to have disappeared in some other way than had
+become increasingly evident.
+
+"Where?" cried Kennedy. "Who?"
+
+"Over on Ten Mile Beach," answered Edwards. "Some fishermen who had
+been out on a cruise and hadn't heard the story. They took the body to
+town, and there it was recognized. They sent word out to us
+immediately."
+
+Waldon had already spun the engine of his tender, which was about the
+fastest thing afloat about Seaville, had taken Edwards over, and we
+were off in a cloud of spray, the nose of the boat many inches above
+the surface of the water.
+
+In the little undertaking establishment at Seaville lay the body of the
+beautiful young matron about whom so much anxiety had been felt. I
+could not help thinking what an end was this for the incomparable
+beauty. At the very height of her brief career the poor little woman's
+life had been suddenly snuffed out. But by what? The body had been
+found, but the mystery had been far from solved.
+
+As Kennedy bent over the body, I heard him murmur to himself, "She had
+everything--everything except happiness."
+
+"Was it drowning that caused her death?" asked Kennedy of the local
+doctor, who also happened to be coroner and had already arrived on the
+scene.
+
+The doctor shook his head. "I don't know," he said doubtfully. "There
+was congestion of the lungs--but I--I can't say but what she might have
+been dead before she fell or was thrown into the water."
+
+Dr. Jermyn stood on one side, now and then putting in a word, but for
+the most part silent unless spoken to. Kennedy, however, was making a
+most minute examination.
+
+As he turned the beautiful head, almost reverently, he saw something
+that evidently attracted his attention. I was standing next to him and,
+between us, I think we cut off the view of the others. There on the
+back of the neck, carefully, had been smeared something transparent,
+almost skin-like, which had easily escaped the attention of the rest.
+
+Kennedy tried to pick it off, but only succeeded in pulling off a very
+minute piece to which the flesh seemed to adhere.
+
+"That's queer," he whispered to me. "Water, naturally, has no effect on
+it, else it would have been washed off long before. Walter," he added,
+"just slip across the street quietly to the drug store and get me a
+piece of gauze soaked with acetone."
+
+As quickly and unostentatiously as I could I did so and handed him the
+wet cloth, contriving at the same time to add Waldon to our barrier,
+for I could see that Kennedy was anxious to be observed as little as
+possible.
+
+"What is it?" I whispered, as he rubbed the transparent skin-like stuff
+off, and dropped the gauze into his pocket.
+
+"A sort of skin varnish," he remarked under his breath, "waterproof and
+so adhesive that it resists pulling off even with a knife without
+taking the cuticle with it."
+
+Beneath, as the skin varnish slowly dissolved under his gentle rubbing,
+he had disclosed several very small reddish spots, like little cuts
+that had been made by means of a very sharp instrument. As he did so,
+he gave them a hasty glance, turned the now stony beautiful head
+straight again, stood up, and resumed his talk with the coroner, who
+was evidently getting more and more bewildered by the case.
+
+Edwards, who had completed the arrangements with the undertaker for the
+care of the body as soon as the coroner released it, seemed completely
+unnerved.
+
+"Jermyn," he said to the doctor, as he turned away and hid his eyes, "I
+can't stand this. The undertaker wants some stuff from the--er--boat,"
+his voice broke over the name which had been hers. "Will you get it for
+me? I'm going up to a hotel here, and I'll wait for you there. But I
+can't go out to the boat--yet."
+
+"I think Mr. Waldon will be glad to take you out in his tender,"
+suggested Kennedy. "Besides, I feel that I'd like a little fresh air as
+a bracer, too, after such a shock."
+
+"What were those little cuts?" I asked as Waldon and Dr. Jermyn
+preceded us through the crowd outside to the pier.
+
+"Some one," he answered in a low tone, "has severed the pneumogastric
+nerves."
+
+"The pneumogastric nerves?" I repeated.
+
+"Yes, the vagus or wandering nerve, the so-called tenth cranial nerve.
+Unlike the other cranial nerves, which are concerned with the special
+senses or distributed to the skin and muscles of the head and neck, the
+vagus, as its name implies, strays downward into the chest and abdomen
+supplying branches to the throat, lungs, heart and stomach and forms an
+important connecting link between the brain and the sympathetic nervous
+system."
+
+We had reached the pier, and a nod from Kennedy discouraged further
+conversation on the subject.
+
+A few minutes later we had reached the Lucie and gone up over her side.
+Kennedy waited until Jermyn had disappeared into the room of Mrs.
+Edwards to get what the undertaker had desired. A moment and he had
+passed quietly into Dr. Jermyn's own room, followed by me. Several
+quick glances about told him what not to waste time over, and at last
+his eye fell on a little portable case of medicines and surgical
+instruments. He opened it quickly and took out a bottle of golden
+yellow liquid.
+
+Kennedy smelled it, then quickly painted some on the back of his hand.
+It dried quickly, like an artificial skin. He had found a bottle of
+skin varnish in Dr. Jermyn's own medicine chest!
+
+We hurried back to the deck, and a few minutes later the doctor
+appeared with a large package.
+
+"Did you ever hear of coating the skin by a substance which is
+impervious to water, smooth and elastic?" asked Kennedy quietly as
+Waldon's tender sped along back to Seaville.
+
+"Why--er, yes," he said frankly, raising his eyes and looking at Craig
+in surprise. "There have been a dozen or more such substances. The best
+is one which I use, made of pyroxylin, the soluble cotton of commerce,
+dissolved in amyl acetate and acetone with some other substances that
+make it perfectly sterile. Why do you ask?"
+
+"Because some one has used a little bit of it to cover a few slight
+cuts on the back of the neck of Mrs. Edwards."
+
+"Indeed?" he said simply, in a tone of mild surprise.
+
+"Yes," pursued Kennedy. "They seem to me to be subcutaneous incisions
+of the neck with a very fine scalpel dividing the two great
+pneumogastric nerves. Of course you know what that would mean--the
+victim would pass away naturally by slow and easy stages in three or
+four days, and all that would appear might be congestion of the lungs.
+They are delicate little punctures and elusive nerves to locate, but
+after all it might be done as painlessly, as simply and as safely as a
+barber might remove some dead hairs. A country coroner might easily
+pass over such evidence at an autopsy--especially if it was concealed
+by skin varnish."
+
+I was surprised at the frankness with which Kennedy spoke, but
+absolutely amazed at the coolness of Jermyn. At first he said
+absolutely nothing. He seemed to be as set in his reticence as he had
+been when we first met.
+
+I watched him narrowly. Waldon, who was driving the boat, had not heard
+what was said, but I had, and I could not conceive how anyone could
+take it so calmly.
+
+Finally Jermyn turned to Kennedy and looked him squarely in the eye.
+"Kennedy," he said slowly, "this is extraordinary--most extraordinary,"
+then, pausing, added, "if true."
+
+"There can be no doubt of the truth," replied Kennedy, eyeing Dr.
+Jermyn just as squarely.
+
+"What do you propose to do about it?" asked the doctor.
+
+"Investigate," replied Kennedy simply. "While Waldon takes these things
+up to the undertaker's, we may as well wait here in the boat. I want
+him to stop on the way back for Mr. Edwards. Then we shall go out to
+the Lucie. He must go, whether he likes it or not."
+
+It was indeed a most peculiar situation as Kennedy and I sat in the
+tender with Dr. Jermyn waiting for Waldon to return with Edwards. Not a
+word was spoken.
+
+The tenseness of the situation was not relieved by the return of Waldon
+with Edwards. Waldon seemed to realize without knowing just what it
+was, that something was about to happen. He drove his boat back to the
+Lucie again in record time. This was Kennedy's turn to be reticent.
+Whatever it was he was revolving in his mind, he answered in scarcely
+more than monosyllables whatever questions were put to him.
+
+"You are not coming aboard?" inquired Edwards in surprise as he and
+Jermyn mounted the steps of the houseboat ladder, and Kennedy remained
+seated in the tender.
+
+"Not yet," replied Craig coolly.
+
+"But I thought you had something to show me. Waldon told me you had."
+
+"I think I shall have in a short time," returned Kennedy. "We shall be
+back immediately. I'm just going to ask Waldon to run over to the
+Nautilus for a few minutes. We'll tow back your launch, too, in case
+you need it."
+
+Waldon had cast off obediently.
+
+"There's one thing sure," I remarked. "Jermyn can't get away from the
+Lucie until we return--unless he swims."
+
+Kennedy did not seem to pay much attention to the remark, for his only
+reply was: "I'm taking a chance by this maneuvering, but I think it
+will work out that I am correct. By the way, Waldon, you needn't put on
+so much speed. I'm in no great hurry to get back. Half an hour will be
+time enough."
+
+"Jermyn? What did you mean by Jermyn?" asked Waldon, as we climbed to
+the deck of the Nautilus.
+
+He had evidently learned, as I had, that it was little use to try to
+quiz Kennedy until he was ready to be questioned and had decided to try
+it on me.
+
+I had nothing to conceal and I told him quite fully all that I knew.
+Actually, I believe if Jermyn had been there, it would have taken both
+Kennedy and myself to prevent violence. As it was I had a veritable
+madman to deal with while Kennedy gathered up leisurely the wireless
+outfit he had installed on the deck of Waldon's yacht. It was only by
+telling him that I would certainly demand that Kennedy leave him behind
+if he did not control his feelings that I could calm him before Craig
+had finished his work on the yacht.
+
+Waldon relieved himself by driving the tender back at top speed to the
+Lucie, and now it seemed that Kennedy had no objection to traveling as
+fast as the many-cylindered engine was capable of going.
+
+As we entered the saloon of the houseboat, I kept close watch over
+Waldon.
+
+Kennedy began by slipping a record on the phonograph in the corner of
+the saloon, then facing us and addressing Edwards particularly.
+
+"You may be interested to know, Mr. Edwards," he said, "that your
+wireless outfit here has been put to a use for which you never intended
+it."
+
+No one said anything, but I am sure that some one in the room then for
+the first time began to suspect what was coming.
+
+"As you know, by the use of an aerial pole, messages may be easily
+received from any number of stations," continued Craig. "Laws, rules
+and regulations may be adopted to shut out interlopers and plug
+busybody ears, but the greater part of whatever is transmitted by the
+Hertzian waves can be snatched down by other wireless apparatus.
+
+"Down below, in that little room of yours," went on Craig, "might sit
+an operator with his ear-phone clamped to his head, drinking in the
+news conveyed surely and swiftly to him through the wireless
+signals--plucking from the sky secrets of finance and," he added,
+leaning forward, "love."
+
+In his usual dramatic manner Kennedy had swung his little audience
+completely with him.
+
+"In other words," he resumed, "it might be used for eavesdropping by a
+wireless wiretapper. Now," he concluded, "I thought that if there was
+any radio detective work being done, I might as well do some, too."
+
+He toyed for a moment with the phonograph record. "I have used," he
+explained, "Marconi's radiotelephone, because in connection with his
+receivers Marconi uses phonographic recorders and on them has captured
+wireless telegraph signals over hundreds of miles.
+
+"He has found that it is possible to receive wireless signals, although
+ordinary records are not loud enough, by using a small microphone on
+the repeating diaphragm and connected with a loud-speaking telephone.
+The chief difficulty was to get a microphone that would carry a
+sufficient current without burning up. There were other difficulties,
+but they have been surmounted and now wireless telegraph messages may
+be automatically recorded and made audible."
+
+Kennedy started the phonograph, running it along, stopping it, taking
+up the record at a new point.
+
+"Listen," he exclaimed at length, "there's something interesting, the
+WXY call--Seaville station--from some one on the Lucie only a few
+minutes ago, sending a message to be relayed by Seaville to the station
+at Beach Park. It seems impossible, but buzzing and ticking forth is
+this message from some one off this very houseboat. It reads: "Miss
+Valerie Fox, Beach Park. I am suspected of the murder of Mrs. Edwards.
+I appeal to you to help me. You must allow me to tell the truth about
+the messages I intercepted for Mrs. Edwards which passed between
+yourself on the ocean and Mr. Edwards in New York via Seaville. You
+rejected me and would not let me save you. Now you must save me."
+
+Kennedy paused, then added, "The message is signed by Dr. Jermyn!"
+
+At once I saw it all. Jermyn had been the unsuccessful suitor for Miss
+Fox's affections. But before I could piece out the rest of the tragic
+story, Kennedy had started the phonograph record at an earlier point
+which he had skipped for the present.
+
+"Here's another record--a brief one--also to Valerie Fox from the
+houseboat: 'Refuse all interviews. Deny everything. Will see you as
+soon as present excitement dies down.'"
+
+Before Kennedy could finish, Waldon had leaped forward, unable longer
+to control his feelings. If Kennedy had not seized his arm, I verily
+believe he would have cast Dr. Jermyn into the bay into which his
+sister had fallen two nights before in her terribly weakened condition.
+
+"Waldon," cried Kennedy, "for God's sake, man--wait! Don't you
+understand? The second message is signed Tracy Edwards."
+
+It came as quite as much a shock of surprise to me as to Waldon.
+
+"Don't you understand?" he repeated. "Your sister first learned from
+Dr. Jermyn what was going on. She moved the Lucie down here near
+Seaville in order to be near the wireless station when the ship bearing
+her rival, Valerie Fox, got in touch with land. With the help of Dr.
+Jermyn she intercepted the wireless messages from the Kronprinz to the
+shore--between her husband and Valerie Fox."
+
+Kennedy was hurrying on now to his irresistible conclusion. "She found
+that he was infatuated with the famous stage beauty, that he was
+planning to marry another, her rival. She accused him of it, threatened
+to defeat his plans. He knew she knew his unfaithfulness. Instead of
+being your sister's murderer, Dr. Jermyn was helping her get the
+evidence that would save both her and perhaps win Miss Fox back to
+himself."
+
+Kennedy had turned sharply on Edwards.
+
+"But," he added, with a glance that crushed any lingering hope that the
+truth had been concealed, "the same night that Dr. Jermyn arrived here,
+you visited your wife. As she slept you severed the nerves that meant
+life or death to her. Then you covered the cuts with the preparation
+which you knew Dr. Jermyn used. You asked him to stay, while you went
+away, thinking that when death came you would have a perfect
+alibi--perhaps a scapegoat. Edwards, the radio detective convicts you!"
+
+
+
+
+CHAPTER X
+
+THE CURIO SHOP
+
+
+Edwards crumpled up as Kennedy and I faced him. There was no escape. In
+fact our greatest difficulty was to protect him from Waldon.
+
+Kennedy's work in the case was over when we had got Edwards ashore and
+in the hands of the authorities. But mine had just begun and it was
+late when I got my story on the wire for the Star.
+
+I felt pretty tired and determined to make up for it by sleeping the
+next day. It was no use, however.
+
+"Why, what's the matter, Mrs. Northrop?" I heard Kennedy ask as he
+opened our door the next morning, just as I had finished dressing.
+
+He had admitted a young woman, who greeted us with nervous,
+wide-staring eyes.
+
+"It's--it's about Archer," she cried, sinking into the nearest chair
+and staring from one to the other of us.
+
+She was the wife of Professor Archer Northrop, director of the
+archeological department at the university. Both Craig and I had known
+her ever since her marriage to Northrop, for she was one of the most
+attractive ladies in the younger set of the faculty, to which Craig
+naturally belonged. Archer had been of the class below us in the
+university. We had hazed him, and out of the mild hazing there had,
+strangely enough, grown a strong friendship.
+
+I recollected quickly that Northrop, according to last reports, had
+been down in the south of Mexico on an archeological expedition. But
+before I could frame, even in my mind, the natural question in a form
+that would not alarm his wife further, Kennedy had it on his lips.
+
+"No bad news from Mitla, I hope?" he asked gently, recalling one of the
+main working stations chosen by the expedition and the reported
+unsettled condition of the country about it. She looked up quickly.
+
+"Didn't you know--he--came back from Vera Cruz yesterday?" she asked
+slowly, then added, speaking in a broken tone, "and--he
+seems--suddenly--to have disappeared. Oh, such a terrible night of
+worry! No word--and I called up the museum, but Doctor Bernardo, the
+curator, had gone, and no one answered. And this morning--I couldn't
+stand it any longer--so I came to you."
+
+"You have no idea, I suppose, of anything that was weighing on his
+mind?" suggested Kennedy.
+
+"No," she answered promptly.
+
+In default of any further information, Kennedy did not pursue this line
+of questioning. I could not determine from his face or manner whether
+he thought the matter might involve another than Mrs. Northrop, or,
+perhaps, something connected with the unsettled condition of the
+country from which her husband had just arrived.
+
+"Have you any of the letters that Archer wrote home?" asked Craig, at
+length.
+
+"Yes," she replied eagerly, taking a little packet from her handbag. "I
+thought you might ask that. I brought them."
+
+"You are an ideal client," commented Craig encouragingly, taking the
+letters. "Now, Mrs. Northrop, be brave. Trust me to run this thing
+down, and if you hear anything let me know immediately."
+
+She left us a moment later, visibly relieved.
+
+Scarcely had she gone when Craig, stuffing the letters into his pocket
+unread, seized his hat, and a moment later was striding along toward
+the museum with his habitual rapid, abstracted step which told me that
+he sensed a mystery.
+
+In the museum we met Doctor Bernardo, a man slightly older than
+Northrop, with whom he had been very intimate. He had just arrived and
+was already deeply immersed in the study of some new and beautiful
+colored plates from the National Museum of Mexico City.
+
+"Do you remember seeing Northrop here yesterday afternoon?" greeted
+Craig, without explaining what had happened.
+
+"Yes," he answered promptly. "I was here with him until very late. At
+least, he was in his own room, working hard, when I left."
+
+"Did you see him go?"
+
+"Why--er--no," replied Bernardo, as if that were a new idea. "I left
+him here--at least, I didn't see him go out."
+
+Kennedy tried the door of Northrop's room, which was at the far end, in
+a corner, and communicated with the hall only through the main floor of
+the museum. It was locked. A pass-key from the janitor quickly opened
+it.
+
+Such a sight as greeted us, I shall never forget. There, in his big
+desk-chair, sat Northrop, absolutely rigid, the most horribly contorted
+look on his features that I have ever seen--half of pain, half of fear,
+as if of something nameless.
+
+Kennedy bent over. His hands were cold.
+
+Northrop had been dead at least twelve hours, perhaps longer. All night
+the deserted museum had guarded its terrible secret.
+
+As Craig peered into his face, he saw, in the fleshy part of the neck,
+just below the left ear, a round red mark, with just a drop or two of
+now black coagulated blood in the center. All around we could see a
+vast amount of miscellaneous stuff, partly unpacked, partly just
+opened, and waiting to be taken out of the wrappings by the now
+motionless hands.
+
+"I suppose you are more or less familiar with what Northrop brought
+back?" asked Kennedy of Bernardo, running his eye over the material in
+the room.
+
+"Yes, reasonably," answered Bernardo. "Before the cases arrived from
+the wharf, he told me in detail what he had managed to bring up with
+him."
+
+"I wish, then, that you would look it over and see if there is anything
+missing," requested Craig, already himself busy in going over the room
+for other evidence.
+
+Doctor Bernardo hastily began taking a mental inventory of the stuff.
+While they worked, I tried vainly to frame some theory which would
+explain the startling facts we had so suddenly discovered.
+
+Mitla, I knew, was south of the city of Oaxaca, and there, in its
+ruined palaces, was the crowning achievement of the old Zapotec kings.
+No ruins in America were more elaborately ornamented or richer in lore
+for the archeologist.
+
+Northrop had brought up porphyry blocks with quaint grecques and much
+hieroglyphic painting. Already unpacked were half a dozen copper axes,
+some of the first of that particular style that had ever been brought
+to the United States. Besides the sculptured stones and the mosaics
+were jugs, cups, vases, little gods, sacrificial stones--enough,
+almost, to equip a new alcove in the museum.
+
+Before Northrop was an idol, a hideous thing on which frogs and snakes
+squatted and coiled. It was a fitting piece to accompany the gruesome
+occupant of the little room in his long, last vigil. In fact, it almost
+sent a shudder over me, and if I had been inclined to the
+superstitious, I should certainly have concluded that this was
+retribution for having disturbed the lares and penates of a dead race.
+
+Doctor Bernardo was going over the material a second time. By the look
+on his face, even I could guess that something was missing.
+
+"What is it?" asked Craig, following the curator closely.
+
+"Why," he answered slowly, "there was an inscription--we were looking
+at it earlier in the day--on a small block of porphyry. I don't see it."
+
+He paused and went back to his search before we could ask him further
+what he thought the inscription was about.
+
+I thought nothing myself at the time of his reticence, for Kennedy had
+gone over to a window back of Northrop and to the left. It was fully
+twenty feet from the downward slope of the campus there, and, as he
+craned his neck out, he noted that the copper leader of the rain pipe
+ran past it a few feet away.
+
+I, too, looked out. A thick group of trees hid the window from the
+avenue beyond the campus wall, and below us, at a corner of the
+building, was a clump of rhododendrons. As Craig bent over the sill, he
+whipped out a pocket lens.
+
+A moment later he silently handed the glass to me. As nearly as I could
+make out, there were five marks on the dust of the sill.
+
+"Finger-prints!" I exclaimed. "Some one has been clinging to the edge
+of the ledge."
+
+"In that case," Craig observed quietly, "there would have been only
+four prints."
+
+I looked again, puzzled. The prints were flat and well separated.
+
+"No," he added, "not finger-prints--toe-prints."
+
+"Toe-prints?" I echoed.
+
+Before he could reply, Craig had dashed out of the room, around, and
+under the window. There, he was carefully going over the soft earth
+around the bushes below.
+
+"What are you looking for?" I asked, joining him.
+
+"Some one--perhaps two--has been here," he remarked, almost under his
+breath. "One, at least, has removed his shoes. See those shoe-prints up
+to this point? The print of a boot-heel in soft earth shows the
+position and contour of every nail head. Bertillon has made a
+collection of such nails, certain types, sizes, and shapes used in
+certain boots, showing often what country the shoes came from. Even the
+number and pattern are significant. Some factories use a fixed number
+of nails and arrange them in a particular manner. I have made my own
+collection of such prints in this country. These were American shoes.
+Perhaps the clue will not lead us anywhere, though, for I doubt whether
+it was an American foot."
+
+Kennedy continued to study the marks.
+
+"He removed his shoes--either to help in climbing or to prevent
+noise--ah--here's the foot! Strange--see how small it is--and broad,
+how prehensile the toes--almost like fingers. Surely that foot could
+never have been encased in American shoes all its life. I shall make
+plaster casts of these, to preserve later."
+
+He was still scouting about on hands and knees in the dampness of the
+rhododendrons. Suddenly he reached his long arm in among the shrubs and
+picked up a little reed stick. On the end of it was a small cylinder of
+buff brown.
+
+He looked at it curiously, dug his nail into the soft mass, then rubbed
+his nail over the tip of his tongue gingerly.
+
+With a wry face, as if the taste were extremely acrid, he moistened his
+handkerchief and wiped off his tongue vigorously.
+
+"Even that minute particle that was on my nail makes my tongue tingle
+and feel numb," he remarked, still rubbing. "Let us go back again. I
+want to see Bernardo."
+
+"Had he any visitors during the day?" queried Kennedy, as he reentered
+the ghastly little room, while the curator stood outside, completely
+unnerved by the tragedy which had been so close to him without his
+apparently knowing it. Kennedy was squeezing out from the little wound
+on Northrop's neck a few drops of liquid on a sterilized piece of glass.
+
+"No; no one," Bernardo answered, after a moment.
+
+"Did you see anyone in the museum who looked suspicious?" asked
+Kennedy, watching Bernardo's face keenly.
+
+"No," he hesitated. "There were several people wandering about among
+the exhibits, of course. One, I recall, late in the afternoon, was a
+little dark-skinned woman, rather good-looking."
+
+"A Mexican?"
+
+"Yes, I should say so. Not of Spanish descent, though. She was rather
+of the Indian type. She seemed to be much interested in the various
+exhibits, asked me several questions, very intelligently, too. Really,
+I thought she was trying to--er--flirt with me."
+
+He shot a glance at Craig, half of confession, half of embarrassment.
+
+"And--oh, yes--there was another--a man, a little man, as I recall,
+with shaggy hair. He looked like a Russian to me. I remember, because
+he came to the door, peered around hastily, and went away. I thought he
+might have got into the wrong part of the building and went to direct
+him right--but before I could get out into the hall, he was gone. I
+remember, too, that, as I turned, the woman had followed me and soon
+was asking other questions--which, I will admit--I was glad to answer."
+
+"Was Northrop in his room while these people were here?"
+
+"Yes; he had locked the door so that none of the students or visitors
+could disturb him."
+
+"Evidently the woman was diverting your attention while the man entered
+Northrop's room by the window," ruminated Craig, as we stood for a
+moment in the outside doorway.
+
+He had already telephoned to our old friend Doctor Leslie, the coroner,
+to take charge of the case, and now was ready to leave. The news had
+spread, and the janitor of the building was waiting to lock the campus
+door to keep back the crowd of students and others.
+
+Our next duty was the painful one of breaking the news to Mrs.
+Northrop. I shall pass it over. Perhaps no one could have done it more
+gently than Kennedy. She did not cry. She was simply dazed. Fortunately
+her mother was with her, had been, in fact, ever since Northrop had
+gone on the expedition.
+
+"Why should anyone want to steal tablets of old Mixtec inscriptions?" I
+asked thoughtfully, as we walked sadly over the campus in the direction
+of the chemistry building. "Have they a sufficient value, even on
+appreciative Fifth Avenue, to warrant murder?"
+
+"Well," he remarked, "it does seem incomprehensible. Yet people do just
+such things. The psychologists tell us that there is a veritable mania
+for possessing such curios. However, it is possible that there may be
+some deeper significance in this case," he added, his face puckered in
+thought.
+
+Who was the mysterious Mexican woman, who the shaggy Russian? I asked
+myself. Clearly, at least, if she existed at all, she was one of the
+millions not of Spanish but of Indian descent in the country south of
+us. As I reasoned it out, it seemed to me as if she must have been an
+accomplice. She could not have got into Northrop's room either before
+or after Doctor Bernardo left. Then, too, the toe-and shoe-prints were
+not hers. But, I figured, she certainly had a part in the plot.
+
+While I was engaged in the vain effort to unravel the tragic affair by
+pure reason, Kennedy was at work with practical science.
+
+He began by examining the little dark cylinder on the end of the reed.
+On a piece of the stuff, broken off, he poured a dark liquid from a
+brown-glass bottle. Then he placed it under a microscope.
+
+"Microscopically," he said slowly, "it consists almost wholly of
+minute, clear granules which give a blue reaction with iodine. They are
+starch. Mixed with them are some larger starch granules, a few plant
+cells, fibrous matter, and other foreign particles. And then, there is
+the substance that gives that acrid, numbing taste." He appeared to be
+vacantly studying the floor.
+
+"What do you think it is?" I asked, unable to restrain myself.
+
+"Aconite," he answered slowly, "of which the active principle is the
+deadly poisonous alkaloid, aconitin."
+
+He walked over and pulled down a well-thumbed standard work on
+toxicology, turned the pages, then began to read aloud:
+
+Pure aconitin is probably the most actively poisonous substance with
+which we are acquainted and, if administered hypodermically, the
+alkaloid is even more powerfully poisonous than when taken by the mouth.
+
+As in the case of most of the poisonous alkaloids, aconitin does not
+produce any decidedly characteristic post-mortem appearances. There is
+no way to distinguish it from other alkaloids, in fact, no reliable
+chemical test. The physiological effects before death are all that can
+be relied on.
+
+Owing to its exceeding toxic nature, the smallness of the dose required
+to produce death, and the lack of tests for recognition, aconitin
+possesses rather more interest in legal medicine than most other
+poisons.
+
+It is one of the few substances which, in the present state of
+toxicology, might be criminally administered and leave no positive
+evidence of the crime. If a small but fatal dose of the poison were to
+be given, especially if it were administered hypodermically, the
+chances of its detection in the body after death would be practically
+none.
+
+
+
+
+CHAPTER XI
+
+THE "PILLAR OF DEATH"
+
+
+I was looking at him fixedly as the diabolical nature of what must have
+happened sank into my mind. Here was a poison that defied detection. I
+could see by the look on Craig's face that that problem, alone, was
+enough to absorb his attention. He seemed fully to realize that we had
+to deal with a criminal so clever that he might never be brought to
+justice.
+
+An idea flashed over me.
+
+"How about the letters?" I suggested.
+
+"Good, Walter!" he exclaimed.
+
+He untied the package which Mrs. Northrop had given him and glanced
+quickly over one after another of the letters.
+
+"Ah!" he exclaimed, fairly devouring one dated at Mitla. "Listen--it
+tells about Northrop's work and goes on:
+
+"'I have been much interested in a cavern, or subterraneo, here, in the
+shape of a cross, each arm of which extends for some twelve feet
+underground. In the center it is guarded by a block of stone popularly
+called "the Pillar of Death." There is a superstition that whoever
+embraces it will die before the sun goes down.
+
+"'From the subterraneo is said to lead a long, underground passage
+across the court to another subterranean chamber which is full of
+Mixtec treasure. Treasure hunters have dug all around it, and it is
+said that two old Indians, only, know of the immense amount of buried
+gold and silver, but that they will not reveal it.'"
+
+I started up. Here was the missing link which I had been waiting for.
+
+"There, at least, is the motive," I blurted out. "That is why Bernardo
+was so reticent. Northrop, in his innocence of heart, had showed him
+that inscription."
+
+Kennedy said nothing as he finally tied up the little packet of letters
+and locked it in his safe. He was not given to hasty generalizations;
+neither was he one who clung doggedly to a preconceived theory.
+
+It was still early in the afternoon. Craig and I decided to drop into
+the museum again in order to see Doctor Bernardo. He was not there and
+we sat down to wait.
+
+Just then the letter box in the door clicked. It was the postman on his
+rounds. Kennedy walked over and picked up the letter.
+
+The postmark bore the words, "Mexico City," and a date somewhat later
+than that on which Northrop had left Vera Cruz. In the lower corner,
+underscored, were the words, "Personal--Urgent."
+
+"I'd like to know what is in that," remarked Craig, turning it over and
+over.
+
+He appeared to be considering something, for he rose suddenly and
+shoved the letter into his pocket.
+
+I followed, and a few moments later, across the campus in his
+laboratory, he was working quickly over an X-ray apparatus. He had
+placed the letter in it.
+
+"These are what are known as 'low' tubes," he explained. "They give out
+'soft rays.'" He continued to work for a few moments, then handed me
+the letter.
+
+"Now, Walter," he said, "if you will just hurry back to the museum and
+replace that letter, I think I will have something that will astonish
+you--though whether it will have any bearing on the case, remains to be
+seen."
+
+"What is it?" I asked, a few minutes later, when I had rejoined him,
+after returning the letter. He was poring intently over what looked
+like a negative.
+
+"The possibility of reading the contents of documents inclosed in a
+sealed envelope," he replied, still studying the shadowgraph closely,
+"has already been established by the well-known English scientist,
+Doctor Hall Edwards. He has been experimenting with the method of using
+X-rays recently discovered by a German scientist, by which radiographs
+of very thin substances, such as a sheet of paper, a leaf, an insect's
+body, may be obtained. These thin substances through which the rays
+used formerly to pass without leaving an impression, can now be
+radiographed."
+
+I looked carefully as he traced out something on the negative. On it
+was easily possible, following his guidance, to read the words
+inscribed on the sheet of paper inside. So admirably defined were all
+the details that even the gum on the envelope and the edges of the
+sheet of paper inside the envelope could be distinguished.
+
+"Any letter written with ink having a mineral basis can be
+radiographed," added Craig. "Even when the sheet is folded in the usual
+way, it is possible by taking a radiograph stereoscopically, to
+distinguish the writing, every detail standing out in relief. Besides,
+it can be greatly magnified, which aids in deciphering it if it is
+indistinct or jumbled up. Some of it looks like mirror writing. Ah," he
+added, "here's something interesting!"
+
+Together we managed to trace out the contents of several paragraphs, of
+which the significant parts were as follows:
+
+ I am expecting that my friend Senora Herreria will be in New York
+by the time you receive this, and should she call on you, I know you
+will accord her every courtesy. She has been in Mexico City for a few
+days, having just returned from Mitla, where she met Professor
+Northrop. It is rumored that Professor Northrop has succeeded in
+smuggling out of the country a very important stone bearing an
+inscription which, I understand, is of more than ordinary interest. I
+do not know anything definite about it, as Senora Herreria is very
+reticent on the matter, but depend on you to find out if possible and
+let me know of it.
+
+According to the rumors and the statements of the senora, it seems that
+Northrop has taken an unfair advantage of the situation down in Oaxaca,
+and I suppose she and others who know about the inscription feel that
+it is really the possession of the government.
+
+You will find that the senora is an accomplished antiquarian and
+scholar. Like many others down here just now, she has a high regard for
+the Japanese. As you know, there exists a natural sympathy between some
+Mexicans and Japanese, owing to what is believed to be a common origin
+of the two races.
+
+In spite of the assertions of many to the contrary, there is little
+doubt left in the minds of students that the Indian races which have
+peopled Mexico were of Mongolian stock. Many words in some dialects are
+easily understood by Chinese immigrants. A secretary of the Japanese
+legation here was able recently to decipher old Mixtec inscriptions
+found in the ruins of Mitla.
+
+Senora Herreria has been much interested in establishing the
+relationship and, I understand, is acquainted with a Japanese curio
+dealer in New York who recently visited Mexico for the same purpose. I
+believe that she wishes to collaborate with him on a monograph on the
+subject, which is expected to have a powerful effect on the public
+opinion both here and at Tokyo.
+
+In regard to the inscription which Northrop has taken with him, I rely
+on you to keep me informed. There seems to be a great deal of mystery
+connected with it, and I am simply hazarding a guess as to its nature.
+If it should prove to be something which might interest either the
+Japanese or ourselves, you can see how important it may be, especially
+in view of the forthcoming mission of General Francisco to Tokyo.
+
+Very sincerely yours,
+
+DR. EMILIO SANCHEZ, Director.
+
+"Bernardo is a Mexican," I exclaimed, as Kennedy finished reading, "and
+there can be no doubt that the woman he mentioned was this Senora
+Herreria."
+
+Kennedy said nothing, but seemed to be weighing the various paragraphs
+in the letter.
+
+"Still," I observed, "so far, the only one against whom we have any
+direct suspicion in the case is the shaggy Russian, whoever he is."
+
+"A man whom Bernardo says looked like a Russian," corrected Craig.
+
+He was pacing the laboratory restlessly.
+
+"This is becoming quite an international affair," he remarked finally,
+pausing before me, his hat on. "Would you like to relax your mind by a
+little excursion among the curio shops of the city? I know something
+about Japanese curios--more, perhaps, than I do of Mexican. It may
+amuse us, even if it doesn't help in solving the mystery. Meanwhile, I
+shall make arrangements for shadowing Bernardo. I want to know just how
+he acts after he reads that letter."
+
+He paused long enough to telephone his instructions to an uptown
+detective agency which could be depended on for such mere routine work,
+then joined me with the significant remark: "Blood is thicker than
+water, anyhow, Walter. Still, even if the Mexicans are influenced by
+sentiment, I hardly think that would account for the interest of our
+friends from across the water in the matter."
+
+I do not know how many of the large and small curio shops of the city
+we visited that afternoon. At another time, I should have enjoyed the
+visits immensely, for anyone seeking articles of beauty will find the
+antique shops of Fifth and Fourth Avenues and the side streets well
+worth visiting.
+
+We came, at length, to one, a small, quaint, dusty rookery, down in a
+basement, entered almost directly from the street. It bore over the
+door a little gilt sign which read simply, "Sato's."
+
+As we entered, I could not help being impressed by the wealth of
+articles in beautiful cloisonne enamel, in mother-of-pearl, lacquer,
+and champleve. There were beautiful little koros, or incense burners,
+vases, and teapots. There were enamels incrusted, translucent, and
+painted, works of the famous Namikawa, of Kyoto, and Namikawa, of
+Tokyo. Satsuma vases, splendid and rare examples of the potter's art,
+crowded gorgeously embroidered screens depicting all sorts of brilliant
+scenes, among others the sacred Fujiyama rising in the stately
+distance. Sato himself greeted us with a ready smile and bow.
+
+"I am just looking for a few things to add to my den," explained
+Kennedy, adding, "nothing in particular, but merely whatever happens to
+strike my fancy."
+
+"Surely, then, you have come to the right shop," greeted Sato. "If
+there is anything that interests you, I shall be glad to show it."
+
+"Thank you," replied Craig. "Don't let me trouble you with your other
+customers. I will call on you if I see anything."
+
+For several minutes, Craig and I busied ourselves looking about, and we
+did not have to feign interest, either.
+
+"Often things are not as represented," he whispered to me, after a
+while, "but a connoiseur can tell spurious goods. These are the real
+thing, mostly."
+
+"Not one in fifty can tell the difference," put in the voice of Sato,
+at his elbow.
+
+"Well, you see I happen to know," Craig replied, not the least
+disconcerted. "You can't always be too sure."
+
+A laugh and a shrug was Sato's answer. "It's well all are not so keen,"
+he said, with a frank acknowledgment that he was not above sharp
+practices.
+
+I glanced now and then at the expressionless face of the curio dealer.
+Was it merely the natural blankness of his countenance that impressed
+me, or was there, in fact, something deep and dark hidden in it,
+something of "East is East and West is West" which I did not and could
+not understand? Craig was admiring the bronzes. He had paused before
+one, a square metal fire-screen of odd design, with the title on a
+card, "Japan Gazing at the World."
+
+It represented Japan as an eagle, with beak and talons of burnished
+gold, resting on a rocky island about which great waves dashed. The
+bird had an air of dignity and conscious pride in its strength, as it
+looked out at the world, a globe revolving in space.
+
+"Do you suppose there is anything significant in that?" I asked,
+pointing to the continent of North America, also in gold and
+prominently in view.
+
+"Ah, honorable sir," answered Sato, before Kennedy could reply, "the
+artist intended by that to indicate Japan's friendliness for America
+and America's greatness."
+
+He was inscrutable. It seemed as if he were watching our every move,
+and yet it was done with a polite cordiality that could not give
+offense.
+
+Behind some bronzes of the Japanese Hercules destroying the demons and
+other mythical heroes was a large alcove, or tokonoma, decorated with
+peacock, stork, and crane panels. Carvings and lacquer added to the
+beauty of it. A miniature chrysanthemum garden heightened the illusion.
+Carved hinoki wood framed the panels, and the roof was supported by
+columns in the old Japanese style, the whole being a compromise between
+the very simple and quiet and the polychromatic. The dark woods, the
+lanterns, the floor tiles of dark red, and the cushions of rich gold
+and yellow were most alluring. It had the genuine fascination of the
+Orient.
+
+"Will the gentlemen drink a little sake?" Sato asked politely.
+
+Craig thanked him and said that we would.
+
+"Otaka!" Sato called.
+
+A peculiar, almost white-skinned attendant answered, and a moment later
+produced four cups and poured out the rice brandy, taking his own
+quietly, apart from us. I watched him drink, curiously. He took the
+cup; then, with a long piece of carved wood, he dipped into the sake,
+shaking a few drops on the floor to the four quarters. Finally, with a
+deft sweep, he lifted his heavy mustache with the piece of wood and
+drank off the draft almost without taking breath.
+
+He was a peculiar man of middle height, with a shock of dark, tough,
+woolly hair, well formed and not bad-looking, with a robust general
+physique, as if his ancestors had been meat eaters. His forehead was
+narrow and sloped backward; the cheekbones were prominent; nose hooked,
+broad and wide, with strong nostrils; mouth large, with thick lips, and
+not very prominent chin. His eyes were perhaps the most noticeable
+feature. They were dark gray, almost like those of a European.
+
+As Otaka withdrew with the empty cups, we rose to continue our
+inspection of the wonders of the shop. There were ivories of all
+descriptions. Here was a two-handled sword, with a very large ivory
+handle, a weirdly carved scabbard, and wonderful steel blade. By the
+expression of Craig's face, Sato knew that he had made a sale.
+
+Craig had been rummaging among some warlike instruments which Sato,
+with the instincts of a true salesman, was now displaying, and had
+picked up a bow. It was short, very strong, and made of pine wood. He
+held it horizontally and twanged the string. I looked up in time to
+catch a pleased expression on the face of Otaka.
+
+"Most people would have held it the other way," commented Sato.
+
+Craig said nothing, but was examining an arrow, almost twenty inches
+long and thick, made of cane, with a point of metal very sharp but
+badly fastened. He fingered the deep blood groove in the scooplike head
+of the arrow and looked at it carefully.
+
+"I'll take that," he said, "only I wish it were one with the regular
+reddish-brown lump in it."
+
+"Oh, but, honorable sir," apologized Sato, "the Japanese law prohibits
+that, now. There are few of those, and they are very valuable."
+
+"I suppose so," agreed Craig. "This will do, though. You have a
+wonderful shop here, Sato. Some time, when I feel richer, I mean to
+come in again. No, thank you, you need not send them; I'll carry them."
+
+We bowed ourselves out, promising to come again when Sato received a
+new consignment from the Orient which he was expecting.
+
+"That other Jap is a peculiar fellow," I observed, as we walked along
+uptown again.
+
+"He isn't a Jap," remarked Craig. "He is an Ainu, one of the aborigines
+who have been driven northward into the island of Yezo."
+
+"An Ainu?" I repeated.
+
+"Yes. Generally thought, now, to be a white race and nearer of kin to
+Europeans than Asiatics. The Japanese have pushed them northward and
+are now trying to civilize them. They are a dirty, hairy race, but when
+they are brought under civilizing influences they adapt themselves to
+their environment and make very good servants. Still, they are on about
+the lowest scale of humanity."
+
+"I thought Otaka was very mild," I commented.
+
+"They are a most inoffensive and peaceable people usually," he
+answered, "good-natured and amenable to authority. But they become
+dangerous when driven to despair by cruel treatment. The Japanese
+government is very considerate of them--but not all Japanese are."
+
+
+
+
+CHAPTER XII
+
+THE ARROW POISON
+
+
+Far into the night Craig was engaged in some very delicate and minute
+microscopic work in the laboratory.
+
+We were about to leave when there was a gentle tap on the door. Kennedy
+opened it and admitted a young man, the operative of the detective
+agency who had been shadowing Bernardo. His report was very brief, but,
+to me at least, significant. Bernardo, on his return to the museum, had
+evidently read the letter, which had agitated him very much, for a few
+moments later he hurriedly left and went downtown to the Prince Henry
+Hotel. The operative had casually edged up to the desk and overheard
+whom he asked for. It was Senora Herreria. Once again, later in the
+evening, he had asked for her, but she was still out.
+
+It was quite early the next morning, when Kennedy had resumed his
+careful microscopic work, that the telephone bell rang, and he answered
+it mechanically. But a moment later a look of intense surprise crossed
+his face.
+
+"It was from Doctor Leslie," he announced, hanging up the receiver
+quickly. "He has a most peculiar case which he wants me to see--a
+woman."
+
+Kennedy called a cab, and, at a furious pace, we dashed across the city
+and down to the Metropolitan Hospital, where Doctor Leslie was waiting.
+He met us eagerly and conducted us to a little room where, lying
+motionless on a bed, was a woman.
+
+She was a striking-looking woman, dark of hair and skin, and in life
+she must have been sensuously attractive. But now her face was drawn
+and contorted--with the same ghastly look that had been on the face of
+Northrop.
+
+"She died in a cab," explained Doctor Leslie, "before they could get
+her to the hospital. At first they suspected the cab driver. But he
+seems to have proved his innocence. He picked her up last night on
+Fifth Avenue, reeling--thought she was intoxicated. And, in fact, he
+seems to have been right. Our tests have shown a great deal of alcohol
+present, but nothing like enough to have had such a serious effect."
+
+"She told nothing of herself?" asked Kennedy.
+
+"No; she was pretty far gone when the cabby answered her signal. All he
+could get out of her was a word that sounded like 'Curio-curio.' He
+says she seemed to complain of something about her mouth and head. Her
+face was drawn and shrunken; her hands were cold and clammy, and then
+convulsions came on. He called an ambulance, but she was past saving
+when it arrived. The numbness seemed to have extended over all her
+body; swallowing was impossible; there was entire loss of her voice as
+well as sight, and death took place by syncope."
+
+"Have you any clue to the cause of her death?" asked Craig.
+
+"Well, it might have been some trouble with her heart, I suppose,"
+remarked Doctor Leslie tentatively.
+
+"Oh, she looks strong that way. No, hardly anything organic."
+
+"Well, then I thought she looked like a Mexican," went on Doctor
+Leslie. "It might be some new tropical disease. I confess I don't know.
+The fact is," he added, lowering his voice, "I had my own theory about
+it until a few moments ago. That was why I called you."
+
+"What do you mean?" asked Craig, evidently bent on testing his own
+theory by the other's ignorance.
+
+Doctor Leslie made no answer immediately, but raised the sheet which
+covered her body and disclosed, in the fleshy part of the upper arm, a
+curious little red swollen mark with a couple of drops of darkened
+blood.
+
+"I thought at first," he added, "that we had at last a genuine
+'poisoned needle' case. You see, that looked like it. But I have made
+all the tests for curare and strychnin without results."
+
+At the mere suggestion, a procession of hypodermic-needle and
+white-slavery stories flashed before me.
+
+"But," objected Kennedy, "clearly this was not a case of kidnaping. It
+is a case of murder. Have you tested for the ordinary poisons?"
+
+Doctor Leslie shook his head. "There was no poison," he said,
+"absolutely none that any of our tests could discover."
+
+Kennedy bent over and squeezed out a few drops of liquid from the wound
+on a microscope slide, and covered them.
+
+"You have not identified her yet," he added, looking up. "I think you
+will find, Leslie, that there is a Senora Herreria registered at the
+Prince Henry who is missing, and that this woman will agree with the
+description of her. Anyhow, I wish you would look it up and let me
+know."
+
+Half an hour later, Kennedy was preparing to continue his studies with
+the microscope when Doctor Bernardo entered. He seemed most solicitous
+to know what progress was being made on the case, and, although Kennedy
+did not tell much, still he did not discourage conversation on the
+subject.
+
+When we came in the night before, Craig had unwrapped and tossed down
+the Japanese sword and the Ainu bow and arrow on a table, and it was
+not long before they attracted Bernardo's attention.
+
+"I see you are a collector yourself," he ventured, picking them up.
+
+"Yes," answered Craig, offhand; "I picked them up yesterday at Sato's.
+You know the place?"
+
+"Oh, yes, I know Sato," answered the curator, seemingly without the
+slightest hesitation. "He has been in Mexico--is quite a student."
+
+"And the other man, Otaka?"
+
+"Other man--Otaka? You mean his wife?"
+
+I saw Kennedy check a motion of surprise and came to the rescue with
+the natural question: "His wife--with a beard and mustache?"
+
+It was Bernardo's turn to be surprised. He looked at me a moment, then
+saw that I meant it, and suddenly his face lighted up.
+
+"Oh," he exclaimed, "that must have been on account of the immigration
+laws or something of the sort. Otaka is his wife. The Ainus are much
+sought after by the Japanese as wives. The women, you know, have a
+custom of tattooing mustaches on themselves. It is hideous, but they
+think it is beautiful."
+
+"I know," I pursued, watching Kennedy's interest in our conversation,
+"but this was not tattooed."
+
+"Well, then, it must have been false," insisted Bernardo.
+
+The curator chatted a few moments, during which I expected Kennedy to
+lead the conversation around to Senora Herreria. But he did not,
+evidently fearing to show his hand.
+
+"What did you make of it?" I asked, when he had gone. "Is he trying to
+hide something?"
+
+"I think he has simplified the case," remarked Craig, leaning back, his
+hands behind his head, gazing up at the ceiling. "Hello, here's Leslie!
+What did you find, Doctor?" The coroner had entered with a look of awe
+on his face, as if Kennedy had directed him by some sort of necromancy.
+
+"It was Senora Herreria!" he exclaimed. "She has been missing from the
+hotel ever since late yesterday afternoon. What do you think of it?"
+
+"I think," replied Kennedy, speaking slowly and deliberately, "that it
+is very much like the Northrop case. You haven't taken that up yet?"
+
+"Only superficially. What do you make of it?" asked the coroner.
+
+"I had an idea that it might be aconitin poisoning," he said.
+
+Leslie glanced at him keenly for a moment. "Then you'll never prove
+anything in the laboratory," he said.
+
+"There are more ways of catching a criminal, Leslie," put in Craig,
+"than are set down in the medico-legal text-books. I shall depend on
+you and Jameson to gather together a rather cosmopolitan crowd here
+to-night."
+
+He said it with a quiet confidence which I could not gainsay, although
+I did not understand. However, mostly with the official aid of Doctor
+Leslie, I followed out his instructions, and it was indeed a strange
+party that assembled that night. There were Doctor Bernardo; Sato, the
+curio dealer; Otaka, the Ainu, and ourselves. Mrs. Northrop, of course,
+could not come.
+
+"Mexico," began Craig, after he had said a few words explaining why he
+had brought us together, "is full of historical treasure. To all
+intents and purposes, the government says, 'Come and dig.' But when
+there are finds, then the government swoops down on them for its own
+national museum. The finder scarcely gets a chance to export them.
+However, now seemed to be the time to Professor Northrop to smuggle his
+finds out of the country.
+
+"But evidently it could not be done without exciting all kinds of
+rumors and suspicions. Stories seem to have spread far and fast about
+what he had discovered. He realized the unsettled condition of the
+country--perhaps wanted to confirm his reading of a certain inscription
+by consultation with one scholar whom he thought he could trust. At any
+rate, he came home."
+
+Kennedy paused, making use of the silence for emphasis. "You have all
+read of the wealth that Cortez found in Mexico. Where are the gold and
+silver of the conquistadores? Gone to the melting pot, centuries ago.
+But is there none left? The Indians believe so. There are persons who
+would stop at nothing--even at murder of American professors, murder of
+their own comrades, to get at the secret."
+
+He laid his hand almost lovingly on his powerful little microscope as
+he resumed on another line of evidence.
+
+"And while we are on the subject of murders, two very similar deaths
+have occurred," he went on. "It is of no use to try to gloss them over.
+Frankly, I suspected that they might have been caused by aconite
+poisoning. But, in the case of such poisoning, not only is the lethal
+dose very small but our chemical methods of detection are nil. The dose
+of the active principle, aconitin nitrate, is about one six-hundredth
+of a grain. There are no color tests, no reactions, as in the case of
+the other organic poisons."
+
+I wondered what he was driving at. Was there, indeed, no test? Had the
+murderer used the safest of poisons--one that left no clue? I looked
+covertly at Sato's face. It was impassive. Doctor Bernardo was visibly
+uneasy as Kennedy proceeded. Cool enough up to the time of the mention
+of the treasure, I fancied, now, that he was growing more and more
+nervous.
+
+Craig laid down on the table the reed stick with the little darkened
+cylinder on the end.
+
+"That," he said, "is a little article which I picked up beneath
+Northrop's window yesterday. It is a piece of anno-noki, or bushi." I
+fancied I saw just a glint of satisfaction in Otaka's eyes.
+
+"Like many barbarians," continued Craig, "the Ainus from time
+immemorial have prepared virulent poisons with which they charged their
+weapons of the chase and warfare. The formulas for the preparations, as
+in the case of other arrow poisons of other tribes, are known only to
+certain members, and the secret is passed down from generation to
+generation as an heirloom, as it were. But in this case it is no longer
+a secret. It has now been proved that the active principle of this
+poison is aconite."
+
+"If that is the case," broke in Doctor Leslie, "it is hopeless to
+connect anyone directly in that way with these murders. There is no
+test for aconitin."
+
+I thought Sato's face was more composed and impassive than ever. Doctor
+Bernardo, however, was plainly excited.
+
+"What--no test--NONE?" asked Kennedy, leaning forward eagerly. Then, as
+if he could restrain the answer to his own question no longer, he shot
+out: "How about the new starch test just discovered by Professor
+Reichert, of the University of Pennsylvania? Doubtless you never
+dreamed that starch may be a means of detecting the nature of a poison
+in obscure cases in criminology, especially in cases where the quantity
+of poison necessary to cause death is so minute that no trace of it can
+be found in the blood.
+
+"The starch method is a new and extremely inviting subject to me. The
+peculiarities of the starch of any plant are quite as distinctive of
+the plant as are those of the hemoglobin crystals in the blood of an
+animal. I have analyzed the evidence of my microscope in this case
+thoroughly. When the arrow poison is introduced subcutaneously--say, by
+a person shooting a poisoned dart, which he afterward removes in order
+to destroy the evidence--the lethal constituents are rapidly absorbed.
+
+"But the starch remains in the wound. It can be recovered and studied
+microscopically and can be definitely recognized. Doctor Reichert has
+published a study of twelve hundred such starches from all sorts of
+plants. In this case, it not only proves to be aconitin but the starch
+granules themselves can be recognized. They came from this piece of
+arrow poison."
+
+Every eye was fixed on him now.
+
+"Besides," he rapped out, "in the soft soil beneath the window of
+Professor Northrop's room, I found footprints. I have only to compare
+the impressions I took there and those of the people in this room, to
+prove that, while the real murderer stood guard below the window, he
+sent some one more nimble up the rain pipe to shoot the poisoned dart
+at Professor Northrop, and, later, to let down a rope by which he, the
+instigator, could gain the room, remove the dart, and obtain the key to
+the treasure he sought."
+
+Kennedy was looking straight at Professor Bernardo.
+
+"A friend of mine in Mexico has written me about an inscription," he
+burst out. "I received the letter only to-day. As nearly as I can
+gather, there was an impression that some of Northrop's stuff would be
+valuable in proving the alleged kinship between Mexico and Japan,
+perhaps to arouse hatred of the United States."
+
+"Yes--that is all very well," insisted Kennedy. "But how about the
+treasure?"
+
+"Treasure?" repeated Bernardo, looking from one of us to another.
+
+"Yes," pursued Craig relentlessly, "the treasure. You are an expert in
+reading the hieroglyphics. By your own statement, you and Northrop had
+been going over the stuff he had sent up. You know it."
+
+Bernardo gave a quick glance from Kennedy to me. Evidently he saw that
+the secret was out.
+
+"Yes," he said huskily, in a low tone, "Northrop and I were to follow
+the directions after we had plotted them out and were to share it
+together on the next expedition, which I could direct as a Mexican
+without so much suspicion. I should still have shared it with his widow
+if this unfortunate affair had not exposed the secret."
+
+Bernardo had risen earnestly.
+
+"Kennedy," he cried, "before God, if you will get back that stone and
+keep the secret from going further than this room, I will prove what I
+have said by dividing the Mixtec treasure with Mrs. Northrop and making
+her one of the richest widows in the country!"
+
+"That is what I wanted to be sure of," nodded Craig. "Bernardo, Senora
+Herreria, of whom your friend wrote to you from Mexico, has been
+murdered in the same way that Professor Northrop was. Otaka was sent by
+her husband to murder Northrop, in order that they might obtain the
+so-called 'Pillar of Death' and the key to the treasure. Then, when the
+senora was no doubt under the influence of sake in the pretty little
+Oriental bower at the curio shop, a quick jab, and Otaka had removed
+one who shared the secret with them."
+
+He had turned and faced the pair.
+
+"Sato," he added, "you played on the patriotism of the senora until you
+wormed from her the treasure secret. Evidently rumors of it had spread
+from Mexican Indians to Japanese visitors. And then, Otaka, all
+jealousy over one whom she, no doubt, justly considered a rival,
+completed your work by sending her forth to die, unknown, on the
+street. Walter, ring up First Deputy O'Connor. The stone is hidden
+somewhere in the curio shop. We can find it without Sato's help. The
+quicker such a criminal is lodged safely in jail, the better for
+humanity."
+
+Sato was on his feet, advancing cautiously toward Craig. I knew the
+dangers, now, of anno-noki, as well as the wonders of jujutsu, and,
+with a leap, I bounded past Bernardo and between Sato and Kennedy.
+
+How it happened, I don't know, but, an instant later, I was sprawling.
+
+Before I could recover myself, before even Craig had a chance to pull
+the hair-trigger of his automatic, Sato had seized the Ainu arrow
+poison from the table, had bitten the little cylinder in half, and had
+crammed the other half into the mouth of Otaka.
+
+
+
+
+CHAPTER XIII
+
+THE RADIUM ROBBER
+
+
+Kennedy simply reached for the telephone and called an ambulance. But
+it was purely perfunctory. Dr. Leslie himself was the only official who
+could handle Sato's case now.
+
+We had planned a little vacation for ourselves, but the planning came
+to naught. The next night we spent on a sleeper. That in itself is work
+to me.
+
+It all came about through a hurried message from Murray Denison,
+president of the Federal Radium Corporation. Nothing would do but that
+he should take both Kennedy and myself with him post-haste to
+Pittsburgh at the first news of what had immediately been called "the
+great radium robbery."
+
+Of course the newspapers were full of it. The very novelty of an
+ultra-modern cracksman going off with something worth upward of a
+couple of hundred thousand dollars--and all contained in a few platinum
+tubes which could be tucked away in a vest pocket--had something about
+it powerfully appealing to the imagination.
+
+"Most ingenious, but, you see, the trouble with that safe is that it
+was built to keep radium IN--not cracksmen OUT," remarked Kennedy, when
+Denison had rushed us from the train to take a look at the little safe
+in the works of the Corporation.
+
+"Breaking into such a safe as this," added Kennedy, after a cursory
+examination, "is simple enough, after all."
+
+It was, however, a remarkably ingenious contrivance, about three feet
+in height and of a weight of perhaps a ton and a half, and all to house
+something weighing only a few grains.
+
+"But," Denison hastened to explain, "we had to protect the radium not
+only against burglars, but, so to speak, against itself. Radium
+emanations pass through steel and experiments have shown that the best
+metal to contain them is lead. So, the difficulty was solved by making
+a steel outer case enclosing an inside leaden shell three inches thick."
+
+Kennedy had been toying thoughtfully with the door.
+
+"Then the door, too, had to be contrived so as to prevent any escape of
+the emanations through joints. It is lathe turned and circular, a 'dead
+fit.' By means of a special contrivance any slight looseness caused by
+wear and tear of closing can be adjusted. And another feature. That is
+the appliance for preventing the loss of emanation when the door is
+opened. Two valves have been inserted into the door and before it is
+opened tubes with mercury are passed through which collect and store
+the emanation."
+
+"All very nice for the radium," remarked Craig cheerfully. "But the
+fellow had only to use an electric drill and the gram or more of radium
+was his."
+
+"I know that--now," ruefully persisted Denison. "But the safe was
+designed for us specially. The fellow got into it and got away, as far
+as I can see, without leaving a clue."
+
+"Except one, of course," interrupted Kennedy quickly.
+
+Denison looked at him a moment keenly, then nodded and said, "Yes--you
+are right. You mean one which he must bear on himself?"
+
+"Exactly. You can't carry a gram or more of radium bromide long with
+impunity. The man to look for is one who in a few days will have
+somewhere on his body a radium burn which will take months to heal. The
+very thing he stole is a veritable Frankenstein's monster bent on the
+destruction of the thief himself!"
+
+Kennedy had meanwhile picked up one of the Corporation's circulars
+lying on a desk. He ran his eye down the list of names.
+
+"So, Hartley Haughton, the broker, is one of your stockholders," mused
+Kennedy.
+
+"Not only one but THE one," replied Denison with obvious pride.
+
+Haughton was a young man who had come recently into his fortune, and,
+while no one believed it to be large, he had cut quite a figure in Wall
+Street.
+
+"You know, I suppose," added Denison, "that he is engaged to Felicie
+Woods, the daughter of Mrs. Courtney Woods?"
+
+Kennedy did not, but said nothing.
+
+"A most delightful little girl," continued Denison thoughtfully. "I
+have known Mrs. Woods for some time. She wanted to invest, but I told
+her frankly that this is, after all, a speculation. We may not be able
+to swing so big a proposition, but, if not, no one can say we have
+taken a dollar of money from widows and orphans."
+
+"I should like to see the works," nodded Kennedy approvingly.
+
+"By all means."
+
+The plant was a row of long low buildings of brick on the outskirts of
+the city, once devoted to the making of vanadium steel. The ore, as
+Denison explained, was brought to Pittsburgh because he had found here
+already a factory which could readily be turned into a plant for the
+extraction of radium. Huge baths and vats and crucibles for the various
+acids and alkalis and other processes used in treating the ore stood at
+various points.
+
+"This must be like extracting gold from sea water," remarked Kennedy
+jocosely, impressed by the size of the plant as compared to the product.
+
+"Except that after we get through we have something infinitely more
+precious than gold," replied Denison, "something which warrants the
+trouble and outlay. Yes, the fact is that the percentage of radium in
+all such ores is even less than of gold in sea water."
+
+"Everything seems to be most carefully guarded," remarked Kennedy as we
+concluded our tour of the well-appointed works.
+
+He had gone over everything in silence, and now at last we had returned
+to the safe.
+
+"Yes," he repeated slowly, as if confirming his original impression,
+"such an amount of radium as was stolen wouldn't occasion immediate
+discomfort to the thief, I suppose, but later no infernal machine could
+be more dangerous to him."
+
+I pictured to myself the series of fearful works of mischief and terror
+that might follow, a curse on the thief worse than that of the weirdest
+curses of the Orient, the danger to the innocent, and the fact that in
+the hands of a criminal it was an instrument for committing crimes that
+might defy detection.
+
+"There is nothing more to do here now," he concluded. "I can see
+nothing for the present except to go back to New York. The telltale
+burn may not be the only clue, but if the thief is going to profit by
+his spoils we shall hear about it best in New York or by cable from
+London, Paris, or some other European city."
+
+Our hurried departure from New York had not given us a chance to visit
+the offices of the Radium Corporation for the distribution of the salts
+themselves. They were in a little old office building on William
+Street, near the drug district and yet scarcely a moment's walk from
+the financial district.
+
+"Our head bookkeeper, Miss Wallace, is ill," remarked Denison when we
+arrived at the office, "but if there is anything I can do to help you,
+I shall be glad to do it. We depend on Miss Wallace a great deal.
+Haughton says she is the brains of the office."
+
+Kennedy looked about the well-appointed suite curiously.
+
+"Is this another of those radium safes?" he asked, approaching one
+similar in appearance to that which had been broken open already.
+
+"Yes, only a little larger."
+
+"How much is in it?"
+
+"Most of our supply. I should say about two and a half grams. Miss
+Wallace has the record."
+
+"It is of the same construction, I presume," pursued Kennedy. "I wonder
+whether the lead lining fits closely to the steel?"
+
+"I think not," considered Denison. "As I remember there was a sort of
+insulating air cushion or something of the sort."
+
+Denison was quite eager to show us about. In fact ever since he had
+hustled us out to view the scene of the robbery, his high nervous
+tension had given us scarcely a moment's rest. For hours he had talked
+radium, until I felt that he, like his metal, must have an
+inexhaustible emanation of words. He was one of those nervous, active
+little men, a born salesman, whether of ribbons or radium.
+
+"We have just gone into furnishing radium water," he went on, bustling
+about and patting a little glass tank.
+
+I looked closely and could see that the water glowed in the dark with a
+peculiar phosphorescence.
+
+"The apparatus for the treatment," he continued, "consists of two glass
+and porcelain receptacles. Inside the larger receptacle is placed the
+smaller, which contains a tiny quantity of radium. Into the larger
+receptacle is poured about a gallon of filtered water. The emanation
+from that little speck of radium is powerful enough to penetrate its
+porcelain holder and charge the water with its curative properties.
+From a tap at the bottom of the tank the patient draws the number of
+glasses of water a day prescribed. For such purposes the emanation
+within a day or two of being collected is as good as radium itself.
+Why, this water is five thousand times as radioactive as the most
+radioactive natural spring water."
+
+"You must have control of a comparatively large amount of the metal,"
+suggested Kennedy.
+
+"We are, I believe, the largest holders of radium in the world," he
+answered. "I have estimated that all told there are not much more than
+ten grams, of which Madame Curie has perhaps three, while Sir Ernest
+Cassel of London is the holder of perhaps as much. We have nearly four
+grams, leaving about six or seven for the rest of the world."
+
+Kennedy nodded and continued to look about.
+
+"The Radium Corporation," went on Denison, "has several large deposits
+of radioactive ore in Utah in what is known as the Poor Little Rich
+Valley, a valley so named because from being about the barrenest and
+most unproductive mineral or agricultural hole in the hills, the sudden
+discovery of the radioactive deposits has made it almost priceless."
+
+He had entered a private office and was looking over some mail that had
+been left on his desk during his absence.
+
+"Look at this," he called, picking up a clipping from a newspaper which
+had been laid there for his attention. "You see, we have them aroused."
+
+We read the clipping together hastily:
+
+PLAN TO CORNER WORLD'S RADIUM
+
+LONDON.--Plans are being matured to form a large corporation for the
+monopoly of the existing and future supply of radium throughout the
+world. The company is to be called Universal Radium, Limited, and the
+capital of ten million dollars will be offered for public subscription
+at par simultaneously in London, Paris and New York.
+
+The company's business will be to acquire mines and deposits of
+radioactive substances as well as the control of patents and processes
+connected with the production of radium. The outspoken purpose of the
+new company is to obtain a world-wide monopoly and maintain the price.
+
+ "Ah--a competitor," commented Kennedy, handing back the clipping.
+
+"Yes. You know radium salts used always to come from Europe. Now we are
+getting ready to do some exporting ourselves. Say," he added excitedly,
+"there's an idea, possibly, in that."
+
+"How?" queried Craig.
+
+"Why, since we should be the principal competitors to the foreign
+mines, couldn't this robbery have been due to the machinations of these
+schemers? To my mind, the United States, because of its supply of
+radium-bearing ores, will have to be reckoned with first in cornering
+the market. This is the point, Kennedy. Would those people who seem to
+be trying to extend their new company all over the world stop at
+anything in order to cripple us at the start?"
+
+How much longer Denison would have rattled on in his effort to explain
+the robbery, I do not know. The telephone rang and a reporter from the
+Record, who had just read my own story in the Star, asked for an
+interview. I knew that it would be only a question of minutes now
+before the other men were wearing a path out on the stairs, and we
+managed to get away before the onrush began.
+
+"Walter," said Kennedy, as soon as we had reached the street. "I want
+to get in touch with Halsey Haughton. How can it be done?"
+
+I could think of nothing better at that moment than to inquire at the
+Star's Wall Street office, which happened to be around the corner. I
+knew the men down there intimately, and a few minutes later we were
+whisked up in the elevator to the office.
+
+They were as glad to see me as I was to see them, for the story of the
+robbery had interested the financial district perhaps more than any
+other.
+
+"Where can I find Halsey Haughton at this hour?" I asked.
+
+"Say," exclaimed one of the men, "what's the matter? There have been
+all kinds of rumors in the Street about him to-day. Did you know he was
+ill?"
+
+"No," I answered. "Where is he?"
+
+"Out at the home of his fiancee, who is the daughter of Mrs. Courtney
+Woods, at Glenclair."
+
+"What's the matter?" I persisted.
+
+"That's just it. No one seems to know. They say--well--they say he has
+a cancer."
+
+Halsey Haughton suffering from cancer? It was such an uncommon thing to
+hear of a young man that I looked up quickly in surprise. Then all at
+once it flashed over me that Denison and Kennedy had discussed the
+matter of burns from the stolen radium. Might not this be, instead of
+cancer, a radium burn?
+
+Kennedy, who had been standing a little apart from me while I was
+talking with the boys, signaled to me with a quick glance not to say
+too much, and a few minutes later we were on the street again.
+
+I knew without being told that he was bound by the next train to the
+pretty little New Jersey suburb of Glenclair.
+
+It was late when we arrived, yet Kennedy had no hesitation in calling
+at the quaint home of Mrs. Courtney Woods on Woodridge Avenue.
+
+Mrs. Woods, a well-set-up woman of middle age, who had retained her
+youth and good looks in a remarkable manner, met us in the foyer.
+Briefly, Kennedy explained that we had just come in from Pittsburgh
+with Mr. Denison and that it was very important that we should see
+Haughton at once.
+
+We had hardly told her the object of our visit when a young woman of
+perhaps twenty-two or three, a very pretty girl, with all the good
+looks of her mother and a freshness which only youth can possess,
+tiptoed quietly downstairs. Her face told plainly that she was deeply
+worried over the illness of her fiance.
+
+"Who is it, mother?" she whispered from the turn in the stairs. "Some
+gentlemen from the company? Hartley's door was open when the bell rang,
+and he thought he heard something said about the Pittsburgh affair."
+
+Though she had whispered, it had not been for the purpose of concealing
+anything from us, but rather that the keen ears of her patient might
+not catch the words. She cast an inquiring glance at us.
+
+"Yes," responded Kennedy in answer to her look, modulating his tone.
+"We have just left Mr. Denison at the office. Might we see Mr. Haughton
+for a moment? I am sure that nothing we can say or do will be as bad
+for him as our going away, now that he knows that we are here."
+
+The two women appeared to consult for a moment.
+
+"Felicie," called a rather nervous voice from the second floor, "is it
+some one from the company?"
+
+"Just a moment, Hartley," she answered, then, lower to her mother,
+added, "I don't think it can do any harm, do you, mother?"
+
+"You remember the doctor's orders, my dear."
+
+Again the voice called her.
+
+"Hang the doctor's orders," the girl exclaimed, with an air of almost
+masculinity. "It can't be half so bad as to have him worry. Will you
+promise not to stay long? We expect Dr. Bryant in a few moments,
+anyway."
+
+
+
+
+CHAPTER XIV
+
+THE SPINTHARISCOPE
+
+
+We followed her upstairs and into Haughton's room, where he was lying
+in bed, propped up by pillows. Haughton certainly was ill. There was no
+mistake about that. He was a tall, gaunt man with an air about him that
+showed that he found illness very irksome. Around his neck was a
+bandage, and some adhesive tape at the back showed that a plaster of
+some sort had been placed there.
+
+As we entered his eyes traveled restlessly from the face of the girl to
+our own in an inquiring manner. He stretched out a nervous hand to us,
+while Kennedy in a few short sentences explained how we had become
+associated with the case and what we had seen already.
+
+"And there is not a clue?" he repeated as Craig finished.
+
+"Nothing tangible yet," reiterated Kennedy. "I suppose you have heard
+of this rumor from London of a trust that is going into the radium
+field internationally?"
+
+"Yes," he answered, "that is the thing you read to me in the morning
+papers, you remember, Felicie. Denison and I have heard such rumors
+before. If it is a fight, then we shall give them a fight. They can't
+hold us up, if Denison is right in thinking that they are at the bottom
+of this--this robbery."
+
+"Then you think he may be right?" shot out Kennedy quickly.
+
+Haughton glanced nervously from Kennedy to me.
+
+"Really," he answered, "you see how impossible it is for me to have an
+opinion? You and Denison have been over the ground. You know much more
+about it than I do. I am afraid I shall have to defer to you."
+
+Again we heard the bell downstairs, and a moment later a cheery voice,
+as Mrs. Woods met some one down in the foyer, asked, "How is the
+patient to-night?"
+
+We could not catch the reply.
+
+"Dr. Bryant, my physician," put in Haughton. "Don't go. I will assume
+the responsibility for your being here. Hello, Doctor. Why, I'm much
+the same to-night, thank you. At least no worse since I took your
+advice and went to bed."
+
+Dr. Bryant was a bluff, hearty man, with the personal magnetism which
+goes with the making of a successful physician. He had mounted the
+stairs quietly but rapidly, evidently prepared to see us.
+
+"Would you mind waiting in this little dressing room?" asked the
+doctor, motioning to another, smaller room adjoining.
+
+He had taken from his pocket a little instrument with a dial face like
+a watch, which he attached to Haughton's wrist. "A pocket instrument to
+measure blood pressure," whispered Craig, as we entered the little room.
+
+While the others were gathered about Haughton, we stood in the next
+room, out of earshot. Kennedy had leaned his elbow on a chiffonier. As
+he looked about the little room, more from force of habit than because
+he thought he might discover anything, Kennedy's eye rested on a glass
+tray on the top in which lay some pins, a collar button or two, which
+Haughton had apparently just taken off, and several other little
+unimportant articles.
+
+Kennedy bent over to look at the glass tray more closely, a puzzled
+look crossed his face, and with a glance at the other room he gathered
+up the tray and its contents.
+
+"Keep up a good courage," said Dr. Bryant. "You'll come out all right,
+Haughton." Then as he left the bedroom he added to us, "Gentlemen, I
+hope you will pardon me, but if you could postpone the remainder of
+your visit until a later day, I am sure you will find it more
+satisfactory."
+
+There was an air of finality about the doctor, though nothing
+unpleasant in it. We followed him down the stairs, and as we did so,
+Felicie, who had been waiting in a reception room, appeared before the
+portieres, her earnest eyes fixed on his kindly face.
+
+"Dr. Bryant," she appealed, "is he--is he, really--so badly?"
+
+The Doctor, who had apparently known her all her life, reached down and
+took one of her hands, patting it with his own in a fatherly way.
+"Don't worry, little girl," he encouraged. "We are going to come out
+all right--all right."
+
+She turned from him to us and, with a bright forced smile which showed
+the stuff she was made of, bade us good night.
+
+Outside, the Doctor, apparently regretting that he had virtually forced
+us out, paused before his car. "Are you going down toward the station?
+Yes? I am going that far. I should be glad to drive you there."
+
+Kennedy climbed into the front seat, leaving me in the rear where the
+wind wafted me their brief conversation as we sped down Woodbridge
+Avenue.
+
+"What seems to be the trouble?" asked Craig.
+
+"Very high blood pressure, for one thing," replied the Doctor frankly.
+
+"For which the latest thing is the radium water cure, I suppose?"
+ventured Kennedy.
+
+"Well, radioactive water is one cure for hardening of the arteries. But
+I didn't say he had hardening of the arteries. Still, he is taking the
+water, with good results. You are from the company?"
+
+Kennedy nodded.
+
+"It was the radium water that first interested him in it. Why, we found
+a pressure of 230 pounds, which is frightful, and we have brought it
+down to 150, not far from normal."
+
+"Still that could have nothing to do with the sore on his neck,"
+hazarded Kennedy.
+
+The Doctor looked at him quickly, then ahead at the path of light which
+his motor shed on the road.
+
+He said nothing, but I fancied that even he felt there was something
+strange in his silence over the new complication. He did not give
+Kennedy a chance to ask whether there were any other such sores.
+
+"At any rate," he said, as he throttled down his engine with a flourish
+before the pretty little Glenclair station, "that girl needn't worry."
+
+There was evidently no use in trying to extract anything further from
+him. He had said all that medical ethics or detective skill could get
+from him. We thanked him and turned to the ticket window to see how
+long we should have to wait.
+
+"Either that doctor doesn't know what he is talking about or he is
+concealing something," remarked Craig, as we paced up and down the
+platform. "I am inclined to read the enigma in the latter way."
+
+Nothing more passed between us during the journey back, and we hurried
+directly to the laboratory, late as it was. Kennedy had evidently been
+revolving something over and over in his mind, for the moment he had
+switched on the light, he unlocked one of his air-and dust-proof
+cabinets and took from it an instrument which he placed on a table
+before him.
+
+It was a peculiar-looking instrument, like a round glass electric
+battery with a cylinder atop, smaller and sticking up like a safety
+valve. On that were an arm, a dial, and a lens fixed in such a way as
+to read the dial. I could not see what else the rather complicated
+little apparatus consisted of, but inside, when Kennedy brought near it
+the pole of a static electric machine two delicate thin leaves of gold
+seemed to fly wide apart when it was charged.
+
+Kennedy had brought the glass tray near the thing. Instantly the leaves
+collapsed and he made a reading through the lens.
+
+"What is it?" I asked.
+
+"A radioscope," he replied, still observing the scale. "Really a very
+sensitive gold leaf electroscope, devised by one of the students of
+Madame Curie. This method of detection is far more sensitive even than
+the spectroscope."
+
+"What does it mean when the leaves collapse?" I asked.
+
+"Radium has been near that tray," he answered. "It is radioactive. I
+suspected it first when I saw that violet color. That is what radium
+does to that kind of glass. You see, if radium exists in a gram of
+inactive matter only to the extent of one in ten-thousand million parts
+its presence can be readily detected by this radioscope, and everything
+that has been rendered radioactive is the same. Ordinarily the air
+between the gold leaves is insulating. Bringing something radioactive
+near them renders the air a good conductor and the leaves fall under
+the radiation."
+
+"Wonderful!" I exclaimed, marveling at the delicacy of it.
+
+"Take radium water," he went on, "sufficiently impregnated with radium
+emanations to be luminous in the dark, like that water of Denison's. It
+would do the same. In fact all mineral waters and the so-called
+curarive muds like fango are slightly radioactive. There seems to be a
+little radium everywhere on earth that experiments have been made, even
+in the interiors of buildings. It is ubiquitous. We are surrounded and
+permeated by radiations--that soil out there on the campus, the air of
+this room, all. But," he added contemplatively, "there is something
+different about that tray. A lot of radium has been near that, and
+recently."
+
+"How about that bandage about Haughton's neck?" I asked suddenly. "Do
+you think radium could have had anything to do with that?" "Well, as to
+burns, there is no particular immediate effect usually, and sometimes
+even up to two weeks or more, unless the exposure has been long and to
+a considerable quantity. Of course radium keeps itself three or four
+degrees warmer than other things about it constantly. But that isn't
+what does the harm. It is continually emitting little corpuscles, which
+I'll explain some other time, traveling all the way from twenty to one
+hundred and thirty thousand miles a second, and these corpuscles
+blister and corrode the flesh like quick-moving missiles bombarding it.
+The gravity of such lesions increases with the purity of the radium.
+For instance I have known an exposure of half an hour to a
+comparatively small quantity through a tube, a box and the clothes to
+produce a blister fifteen days later. Curie said he wouldn't trust
+himself in a room with a kilogram of it. It would destroy his eyesight,
+burn off his skin and kill him eventually. Why, even after a slight
+exposure your clothes are radioactive--the electroscope will show that."
+
+He was still fumbling with the glass plate and the various articles on
+it.
+
+"There's something very peculiar about all this," he muttered, almost
+to himself.
+
+Tired by the quick succession of events of the past two days, I left
+Kennedy still experimenting in his laboratory and retired, still
+wondering when the real clue was to develop. Who could it have been who
+bore the tell-tale burn? Was the mark hidden by the bandage about
+Haughton's neck the brand of the stolen tubes? Or were there other
+marks on his body which we could not see?
+
+No answer came to me, and I fell asleep and woke up without a radiation
+of light on the subject. Kennedy spent the greater part of the day
+still at work at his laboratory, performing some very delicate
+experiments. Finding nothing to do there, I went down to the Star
+office and spent my time reading the reports that came in from the
+small army of reporters who had been assigned to run down clues in the
+case which was the sensation of the moment. I have always felt my own
+lips sealed in such cases, until the time came that the story was
+complete and Kennedy released me from any further need of silence. The
+weird and impossible stories which came in not only to the Star but to
+the other papers surely did make passable copy in this instance, but
+with my knowledge of the case I could see that not one of them brought
+us a step nearer the truth.
+
+One thing which uniformly puzzled the newspapers was the illness of
+Haughton and his enforced idleness at a time which was of so much
+importance to the company which he had promoted and indeed very largely
+financed. Then, of course, there was the romantic side of his
+engagement to Felicie Woods.
+
+Just what connection Felicie Woods had with the radium robbery if any,
+I was myself unable quite to fathom. Still, that made no difference to
+the papers. She was pretty and therefore they published her picture,
+three columns deep, with Haughton and Denison, who were intimately
+concerned with the real loss in little ovals perhaps an inch across and
+two inches in the opposite dimension.
+
+The late afternoon news editions had gone to press, and I had given up
+in despair, determined to go up to the laboratory and sit around idly
+watching Kennedy with his mystifying experiments, in preference to
+waiting for him to summon me.
+
+I had scarcely arrived and settled myself to an impatient watch, when
+an automobile drove up furiously, and Denison himself, very excited,
+jumped out and dashed into the laboratory.
+
+"What's the matter?" asked Kennedy, looking up from a test tube which
+he had been examining, with an air for all the world expressive of "Why
+so hot, little man?"
+
+"I've had a threat," ejaculated Denison.
+
+He laid on one of the laboratory tables a letter, without heading and
+without signature, written in a disguised hand, with an evident attempt
+to simulate the cramped script of a foreign penmanship.
+
+"I know who did the Pittsburgh job. The same party is out to ruin
+Federal Radium. Remember Pittsburgh and be prepared!
+
+"A STOCKHOLDER."
+
+"Well?" demanded Kennedy, looking up.
+
+"That can have only one meaning," asserted Denison.
+
+"What is that?" inquired Kennedy coolly, as if to confirm his own
+interpretation.
+
+"Why, another robbery--here in New York, of course."
+
+"But who would do it?" I asked.
+
+"Who?" repeated Denison. "Some one representing that European combine,
+of course. That is only part of the Trust method--ruin of competitors
+whom they cannot absorb."
+
+"Then you have refused to go into the combine? You know who is backing
+it?"
+
+"No--no," admitted Denison reluctantly. "We have only signified our
+intent to go it alone, as often as anyone either with or without
+authority has offered to buy us out. No, I do not even know who the
+people are. They never act in the open. The only hints I have ever
+received were through perfectly reputable brokers acting for others."
+
+"Does Haughton know of this note?" asked Kennedy.
+
+"Yes. As soon as I received it, I called him up."
+
+"What did he say?"
+
+"He said to disregard it. But--you know what condition he is in. I
+don't know what to do, whether to surround the office by a squad of
+detectives or remove the radium to a regular safety deposit vault, even
+at the loss of the emanation. Haughton has left it to me."
+
+Suddenly the thought flashed across my mind that perhaps Haughton could
+act in this uninterested fashion because he had no fear of ruin either
+way. Might he not be playing a game with the combination in which he
+had protected himself so that he would win, no matter what happened?
+
+"What shall I do?" asked Denison. "It is getting late."
+
+"Neither," decided Kennedy.
+
+Denison shook his head. "No," he said, "I shall have some one watch
+there, anyhow."
+
+
+
+
+CHAPTER XV
+
+THE ASPHYXIATING SAFE
+
+
+Denison had scarcely gone to arrange for some one to watch the office
+that night, when Kennedy, having gathered up his radioscope and packed
+into a parcel a few other things from various cabinets, announced:
+"Walter, I must see that Miss Wallace, right away. Denison has already
+given me her address. Call a cab while I finish clearing up here. I
+don't like the looks of this thing, even if Haughton does neglect it."
+
+We found Miss Wallace at a modest boarding-house in an old but still
+respectable part of the city. She was a very pretty girl, of the
+slender type, rather a business woman than one given much to amusement.
+She had been ill and was still ill. That was evident from the
+solicitous way in which the motherly landlady scrutinized two strange
+callers.
+
+Kennedy presented a card from Denison, and she came down to the parlor
+to see us.
+
+"Miss Wallace," began Kennedy, "I know it is almost cruel to trouble
+you when you are not feeling like office work, but since the robbery of
+the safe at Pittsburgh, there have been threats of a robbery of the New
+York office."
+
+She started involuntarily, and it was evident, I thought, that she was
+in a very high-strung state.
+
+"Oh," she cried, "why, the loss means ruin to Mr. Denison!"
+
+There were genuine tears in her eyes as she said it.
+
+"I thought you would be willing to aid us," pursued Kennedy
+sympathetically. "Now, for one thing, I want to be perfectly sure just
+how much radium the Corporation owns, or rather owned before the first
+robbery."
+
+"The books will show it," she said simply.
+
+"They will?" commented Kennedy. "Then if you will explain to me briefly
+just the system you used in keeping account of it, perhaps I need not
+trouble you any more."
+
+"I'll go down there with you," she answered bravely. "I'm better
+to-day, anyhow, I think."
+
+She had risen, but it was evident that she was not as strong as she
+wanted us to think.
+
+"The least I can do is to make it as easy as possible by going in a
+car," remarked Kennedy, following her into the hall where there was a
+telephone.
+
+The hallway was perfectly dark, yet as she preceded us I could see that
+the diamond pin which held her collar in the back sparkled as if a
+lighted candle had been brought near it. I had noticed in the parlor
+that she wore a handsome tortoiseshell comb set with what I thought
+were other brilliants, but when I looked I saw now that there was not
+the same sparkle to the comb which held her dark hair in a soft mass. I
+noticed these little things at the time, not because I thought they had
+any importance, but merely by chance, wondering at the sparkle of the
+one diamond which had caught my eye.
+
+"What do you make of her?" I asked as Kennedy finished telephoning.
+
+"A very charming and capable girl," he answered noncommittally.
+
+"Did you notice how that diamond in her neck sparkled?" I asked quickly.
+
+He nodded. Evidently it had attracted his attention, too.
+
+"What makes it?" I pursued.
+
+"Well, you know radium rays will make a diamond fluoresce in the dark."
+
+"Yes," I objected, "but how about those in the comb?"
+
+"Paste, probably," he answered tersely, as we heard her foot on the
+landing. "The rays won't affect paste."
+
+It was indeed a shame to take advantage of Miss Wallace's loyalty to
+Denison, but she was so game about it that I knew only the utmost
+necessity on Kennedy's part would have prompted him to do it. She had a
+key to the office so that it was not necessary to wait for Denison, if
+indeed we could have found him.
+
+Together she and Kennedy went over the records. It seemed that there
+were in the safe twenty-five platinum tubes of one hundred milligrams
+each, and that there had been twelve of the same amount at Pittsburgh.
+Little as it seemed in weight it represented a fabulous fortune.
+
+"You have not the combination?" inquired Kennedy.
+
+"No. Only Mr. Denison has that. What are you going to do to protect the
+safe to-night?" she asked.
+
+"Nothing especially," evaded Kennedy.
+
+"Nothing?" she repeated in amazement.
+
+"I have another plan," he said, watching her intently. "Miss Wallace,
+it was too much to ask you to come down here. You are ill."
+
+She was indeed quite pale, as if the excitement had been an
+overexertion.
+
+"No, indeed," she persisted. Then, feeling her own weakness, she moved
+toward the door of Denison's office where there was a leather couch.
+"Let me rest here a moment. I do feel queer. I--"
+
+She would have fallen if he had not sprung forward and caught her as
+she sank to the floor, overcome by the exertion.
+
+Together we carried her in to the couch, and as we did so the comb from
+her hair clattered to the floor.
+
+Craig threw open the window, and bathed her face with water until there
+was a faint flutter of the eyelids.
+
+"Walter," he said, as she began to revive, "I leave her to you. Keep
+her quiet for a few moments. She has unintentionally given me just the
+opportunity I want."
+
+While she was yet hovering between consciousness and unconsciousness on
+the couch, he had unwrapped the package which he had brought with him.
+For a moment he held the comb which she had dropped near the
+radioscope. With a low exclamation of surprise he shoved it into his
+pocket.
+
+Then from the package he drew a heavy piece of apparatus which looked
+as if it might be the motor part of an electric fan, only in place of
+the fan he fitted a long, slim, vicious-looking steel bit. A flexible
+wire attached the thing to the electric light circuit and I knew that
+it was an electric drill. With his coat off he tugged at the little
+radium safe until he had moved it out, then dropped on his knees behind
+it and switched the current on in the electric drill.
+
+It was a tedious process to drill through the steel of the outer casing
+of the safe and it was getting late. I shut the door to the office so
+that Miss Wallace could not see.
+
+At last by the cessation of the low hum of the boring, I knew that he
+had struck the inner lead lining. Quietly I opened the door and stepped
+out. He was injecting something from an hermetically sealed lead tube
+into the opening he had made and allowing it to run between the two
+linings of lead and steel. Then using the tube itself he sealed the
+opening he had made and dabbed a little black over it.
+
+Quickly he shoved the safe back, then around it concealed several small
+coils with wires also concealed and leading out through a window to a
+court.
+
+"We'll catch the fellow this time," he remarked as he worked. "If you
+ever have any idea, Walter, of going into the burglary business, it
+would be well to ascertain if the safes have any of these little
+selenium cells as suggested by my friend, Mr. Hammer, the inventor. For
+by them an alarm can be given miles away the moment an intruder's
+bull's-eye falls on a hidden cell sensitive to light."
+
+While I was delegated to take Miss Wallace home, Kennedy made
+arrangements with a small shopkeeper on the ground floor of a building
+that backed up on the court for the use of his back room that night,
+and had already set up a bell actuated by a system of relays which the
+weak current from the selenium cells could operate.
+
+It was not until nearly midnight that he was ready to leave the
+laboratory again, where he had been busily engaged in studying the
+tortoiseshell comb which Miss Wallace in her weakness had forgotten.
+
+The little shopkeeper let us in sleepily and Kennedy deposited a large
+round package on a chair in the back of the shop, as well as a long
+piece of rubber tubing. Nothing had happened so far.
+
+As we waited the shopkeeper, now wide awake and not at all unconvinced
+that we were bent on some criminal operation, hung around. Kennedy did
+not seem to care. He drew from his pocket a little shiny brass
+instrument in a lead case, which looked like an abbreviated microscope.
+
+"Look through it," he said, handing it to me.
+
+I looked and could see thousands of minute sparks.
+
+"What is it?" I asked.
+
+"A spinthariscope. In that it is possible to watch the bombardment of
+the countless little corpuscles thrown off by radium, as they strike on
+the zinc blende crystal which forms the base. When radium was
+originally discovered, the interest was merely in its curious
+properties, its power to emit invisible rays which penetrated solid
+substances and rendered things fluorescent, of expending energy without
+apparent loss.
+
+"Then came the discovery," he went on, "of its curative powers. But the
+first results were not convincing. Still, now that we know the reasons
+why radium may be dangerous and how to protect ourselves against them
+we know we possess one of the most wonderful of curative agencies."
+
+I was thinking rather of the dangers than of the beneficence of radium
+just now, but Kennedy continued.
+
+"It has cured many malignant growths that seemed hopeless, brought back
+destroyed cells, exercised good effects in diseases of the liver and
+intestines and even the baffling diseases of the arteries. The reason
+why harm, at first, as well as good came, is now understood. Radium
+emits, as I told you before, three kinds of rays, the alpha, beta, and
+gamma rays, each with different properties. The emanation is another
+matter. It does not concern us in this case, as you will see."
+
+Fascinated as I was by the mystery of the case, I began to see that he
+was gradually arriving at an explanation which had baffled everyone
+else.
+
+"Now, the alpha rays are the shortest," he launched forth, "in length
+let us say one inch. They exert a very destructive effect on healthy
+tissue. That is the cause of injury. They are stopped by glass,
+aluminum and other metals, and are really particles charged with
+positive electricity. The beta rays come next, say, about an inch and a
+half. They stimulate cell growth. Therefore they are dangerous in
+cancer, though good in other ways. They can be stopped by lead, and are
+really particles charged with negative electricity. The gamma rays are
+the longest, perhaps three inches long, and it is these rays which
+effect cures, for they check the abnormal and stimulate the normal
+cells. They penetrate lead. Lead seems to filter them out from the
+other rays. And at three inches the other rays don't reach, anyhow. The
+gamma rays are not charged with electricity at all, apparently."
+
+He had brought a little magnet near the spinthariscope. I looked into
+it.
+
+"A magnet," he explained, "shows the difference between the alpha,
+beta, and gamma rays. You see those weak and wobbly rays that seem to
+fall to one side? Those are the alpha rays. They have a strong action,
+though, on tissues and cells. Those falling in the other direction are
+the beta rays. The gamma rays seem to flow straight."
+
+"Then it is the alpha rays with which we are concerned mostly now?" I
+queried, looking up.
+
+"Exactly. That is why, when radium is unprotected or insufficiently
+protected and comes too near, it is destructive of healthy cells,
+produces burns, sores, which are most difficult to heal. It is with the
+explanation of such sores that we must deal."
+
+It was growing late. We had waited patiently now for some time. Kennedy
+had evidently reserved this explanation, knowing we should have to
+wait. Still nothing happened.
+
+Added to the mystery of the violet-colored glass plate was now that of
+the luminescent diamond. I was about to ask Kennedy point-blank what he
+thought of them, when suddenly the little bell before us began to buzz
+feebly under the influence of a current.
+
+I gave a start. The faithful little selenium cell burglar alarm had
+done the trick. I knew that selenium was a good conductor of
+electricity in the light, poor in the dark. Some one had, therefore,
+flashed a light on one of the cells in the Corporation office. It was
+the moment for which Kennedy had prepared.
+
+Seizing the round package and the tubing, he dashed out on the street
+and around the corner. He tried the door opening into the Radium
+Corporation hallway. It was closed, but unlocked. As it yielded and we
+stumbled in, up the old worn wooden stairs of the building, I knew that
+there must be some one there.
+
+A terrific, penetrating, almost stunning odor seemed to permeate the
+air even in the hall.
+
+Kennedy paused at the door of the office, tried it, found it unlocked,
+but did not open it.
+
+"That smell is ethyldichloracetate," he explained. "That was what I
+injected into the air cushion of that safe between the two linings. I
+suppose my man here used an electric drill. He might have used thermit
+or an oxyacetylene blowpipe for all I would care. These fumes would
+discourage a cracksman from 'soup' to nuts," he laughed, thoroughly
+pleased at the protection modern science had enabled him to devise.
+
+As we stood an instant by the door, I realized what had happened. We
+had captured our man. He was asphyxiated!
+
+Yet how were we to get to him? Would Craig leave him in there, perhaps
+to die? To go in ourselves meant to share his fate, whatever might be
+the effect of the drug.
+
+Kennedy had torn the wrapping off the package. From it he drew a huge
+globe with bulging windows of glass in the front and several curious
+arrangements on it at other points. To it he fitted the rubber tubing
+and a little pump. Then he placed the globe over his head, like a
+diver's helmet, and fastened some air-tight rubber arrangement about
+his neck and shoulders.
+
+"Pump, Walter!" he shouted. "This is an oxygen helmet such as is used
+in entering mines filled with deadly gases."
+
+Without another word he was gone into the blackness of the noxious
+stifle which filled the Radium Corporation office since the cracksman
+had struck the unexpected pocket of rapidly evaporating stuff.
+
+I pumped furiously.
+
+Inside I could hear him blundering around. What was he doing?
+
+He was coming back slowly. Was he, too, overcome?
+
+As he emerged into the darkness of the hallway where I myself was
+almost sickened, I saw that he was dragging with him a limp form.
+
+A rush of outside air from the street door seemed to clear things a
+little. Kennedy tore off the oxygen helmet and dropped down on his
+knees beside the figure, working its arms in the most approved manner
+of resuscitation.
+
+"I think we can do it without calling on the pulmotor," he panted.
+"Walter, the fumes have cleared away enough now in the outside office.
+Open a window--and keep that street door open, too."
+
+I did so, found the switch and turned on the lights.
+
+It was Denison himself!
+
+For many minutes Kennedy worked over him. I bent down, loosened his
+collar and shirt, and looked eagerly at his chest for the tell-tale
+marks of the radium which I felt sure must be there. There was not even
+a discoloration.
+
+Not a word was said, as Kennedy brought the stupefied little man around.
+
+Denison, pale, shaken, was leaning back now in a big office chair,
+gasping and holding his head.
+
+Kennedy, before him, reached down into his pocket and handed him the
+spinthariscope.
+
+"You see that?" he demanded.
+
+Denison looked through the eyepiece.
+
+"Wh--where did you get so much of it?" he asked, a queer look on his
+face.
+
+"I got that bit of radium from the base of the collar button of Hartley
+Haughton," replied Kennedy quietly, "a collar button which some one
+intimate with him had substituted for his own, bringing that deadly
+radium with only the minutest protection of a thin strip of metal close
+to the back of his neck, near the spinal cord and the medulla oblongata
+which controls blood pressure. That collar button was worse than the
+poisoned rings of the Borgias. And there is more radium in the pretty
+gift of a tortoiseshell comb with its paste diamonds which Miss Wallace
+wore in her hair. Only a fraction of an inch, not enough to cut off the
+deadly alpha rays, protected the wearers of those articles."
+
+He paused a moment, while surging through my mind came one after
+another the explanations of the hitherto inexplicable. Denison seemed
+almost to cringe in the chair, weak already from the fumes.
+
+"Besides," went on Kennedy remorselessly, "when I went in there to drag
+you out, I saw the safe open. I looked. There was nothing in those
+pretty platinum tubes, as I suspected. European trust--bah! All the
+cheap devices of a faker with a confederate in London to send a
+cablegram--and another in New York to send a threatening letter."
+
+Kennedy extended an accusing forefinger at the man cowering before him.
+
+"This is nothing but a get-rich-quick scheme, Denison. There never was
+a milligram of radium in the Poor Little Rich Valley, not a milligram
+here in all the carefully kept reports of Miss Wallace--except what was
+bought outside by the Corporation with the money it collected from its
+dupes. Haughton has been fleeced. Miss Wallace, blinded by her loyalty
+to you--you will always find such a faithful girl in such schemes as
+yours--has been fooled.
+
+"And how did you repay it? What was cleverer, you said to yourself,
+than to seem to be robbed of what you never had, to blame it on a
+bitter rival who never existed? Then to make assurance doubly sure, you
+planned to disable, perhaps get rid of the come-on whom you had
+trimmed, and the faithful girl whose eyes you had blinded to your
+gigantic swindle.
+
+"Denison," concluded Kennedy, as the man drew back, his very face
+convicting him, "Denison, you are the radium robber--robber in another
+sense!"
+
+
+
+
+CHAPTER XVI
+
+THE DEAD LINE
+
+
+Maiden Lane, no less than Wall Street, was deeply interested in the
+radium case. In fact, it seemed that one case in this section of the
+city led to another.
+
+Naturally, the Star and the other papers made much of the capture of
+Denison. Still, I was not prepared for the host of Maiden Lane cases
+that followed. Many of them were essentially trivial. But one proved to
+be of extreme importance.
+
+"Professor Kennedy, I have just heard of your radium case, and I--I
+feel that I can--trust you."
+
+There was a note of appeal in the hesitating voice of the tall, heavily
+veiled woman whose card had been sent up to us with a nervous "Urgent"
+written across its face.
+
+It was very early in the morning, but our visitor was evidently
+completely unnerved by some news which she had just received and which
+had sent her posting to see Craig.
+
+Kennedy met her gaze directly with a look that arrested her involuntary
+effort to avoid it again. She must have read in his eyes more than in
+his words that she might trust him.
+
+"I--I have a confession to make," she faltered.
+
+"Please sit down, Mrs. Moulton," he said simply. "It is my business to
+receive confidences--and to keep them."
+
+She sank into, rather than sat down in, the deep leather rocker beside
+his desk, and now for the first time raised her veil.
+
+Antoinette Moulton was indeed stunning, an exquisite creature with a
+wonderful charm of slender youth, brightness of eye and brunette
+radiance.
+
+I knew that she had been on the musical comedy stage and had had a
+rapid rise to a star part before her marriage to Lynn Moulton, the
+wealthy lawyer, almost twice her age. I knew also that she had given up
+the stage, apparently without a regret. Yet there was something strange
+about the air of secrecy of her visit. Was there a hint in it of a
+disagreement between the Moultons, I wondered, as I waited while
+Kennedy reassured her.
+
+Her distress was so unconcealed that Craig, for the moment, laid aside
+his ordinary inquisitorial manner. "Tell me just as much or just as
+little as you choose, Mrs. Moulton," he added tactfully. "I will do my
+best."
+
+A look almost of gratitude crossed her face.
+
+"When we were married," she began again, "my husband gave me a
+beautiful diamond necklace. Oh, it must have been worth a hundred
+thousand dollars easily. It was splendid. Everyone has heard of it. You
+know, Lynn--er--Mr. Moulton, has always been an enthusiastic collector
+of jewels."
+
+She paused again and Kennedy nodded reassuringly. I knew the thought in
+his mind. Moulton had collected one gem that was incomparable with all
+the hundred thousand dollar necklaces in existence.
+
+"Several months ago." she went on rapidly, still avoiding his eyes and
+forcing the words from her reluctant lips, "I--oh, I needed
+money--terribly."
+
+She had risen and faced him, pressing her daintily gloved hands
+together in a little tremble of emotion which was none the less genuine
+because she had studied the art of emotion.
+
+"I took the necklace to a jeweler, Herman Schloss, of Maiden Lane, a
+man with whom my husband had often had dealings and whom I thought I
+could trust. Under a promise of secrecy he loaned me fifty thousand
+dollars on it and had an exact replica in paste made by one of his best
+workmen. This morning, just now, Mr. Schloss telephoned me that his
+safe had been robbed last night. My necklace is gone!"
+
+She threw out her hands in a wildly appealing gesture.
+
+"And if Lynn finds that the necklace in our wall safe is of paste--as
+he will find, for he is an expert in diamonds--oh--what shall I do?
+Can't you--can't you find my necklace?"
+
+Kennedy was following her now eagerly. "You were blackmailed out of the
+money?" he queried casually, masking his question.
+
+There was a sudden, impulsive drooping of her mouth, an evasion and
+keen wariness in her eyes. "I can't see that that has anything to do
+with the robbery," she answered in a low voice.
+
+"I beg your pardon," corrected Kennedy quickly. "Perhaps not. I'm
+sorry. Force of habit, I suppose. You don't know anything more about
+the robbery?"
+
+"N--no, only that it seems impossible that it could have happened in a
+place that has the wonderful burglar alarm protection that Mr. Schloss
+described to me."
+
+"You know him pretty well?"
+
+"Only through this transaction," she replied hastily. "I wish to heaven
+I had never heard of him."
+
+The telephone rang insistently.
+
+"Mrs. Moulton," said Kennedy, as he returned the receiver to the hook,
+"it may interest you to know that the burglar alarm company has just
+called me up about the same case. If I had need of an added incentive,
+which I hope you will believe I have not, that might furnish it. I will
+do my best," he repeated.
+
+"Thank you--a thousand times," she cried fervently, and, had I been
+Craig, I think I should have needed no more thanks than the look she
+gave him as he accompanied her to the door of our apartment.
+
+It was still early and the eager crowds were pushing their way to
+business through the narrow network of downtown streets as Kennedy and
+I entered a large office on lower Broadway in the heart of the jewelry
+trade and financial district.
+
+"One of the most amazing robberies that has ever been attempted has
+been reported to us this morning," announced James McLear, manager of
+the Hale Electric Protection, adding with a look half of anxiety, half
+of skepticism, "that is, if it is true."
+
+McLear was a stocky man, of powerful build and voice and a general
+appearance of having been once well connected with the city detective
+force before an attractive offer had taken him into this position of
+great responsibility.
+
+"Herman Schloss, one of the best known of Maiden Lane jewelers," he
+continued, "has been robbed of goods worth two or three hundred
+thousand dollars--and in spite of every modern protection. So that you
+will get it clearly, let me show you what we do here."
+
+He ushered us into a large room, on the walls of which were hundreds of
+little indicators. From the front they looked like rows of little
+square compartments, tier on tier, about the size of ordinary post
+office boxes. Closer examination showed that each was equipped with a
+delicate needle arranged to oscillate backward and forward upon the
+very minutest interference with the electric current. Under the boxes,
+each of which bore a number, was a series of drops and buzzers numbered
+to correspond with the boxes.
+
+"In nearly every office in Maiden Lane where gems and valuable jewelry
+are stored," explained McLear, "this electrical system of ours is
+installed. When the safes are closed at night and the doors swung
+together, a current of electricity is constantly shooting around the
+safes, conducted by cleverly concealed wires. These wires are picked up
+by a cable system which finds its way to this central office. Once
+here, the wires are safeguarded in such manner that foreign currents
+from other wires or from lightning cannot disturb the system."
+
+We looked with intense interest at this huge electrical pulse that felt
+every change over so vast and rich an area.
+
+"Passing a big dividing board," he went on, "they are distributed and
+connected each in its place to the delicate tangent galvanometers and
+sensitive indicators you see in this room. These instantly announce the
+most minute change in the working of the current, and each office has a
+distinct separate metallic circuit. Why, even a hole as small as a lead
+pencil in anything protected would sound the alarm here."
+
+Kennedy nodded appreciatively.
+
+"You see," continued McLear, glad to be able to talk to one who
+followed him so closely, "it is another evidence of science finding for
+us greater security in the use of a tiny electric wire than in massive
+walls of steel and intricate lock devices. But here is a case in which,
+it seems, every known protection has failed. We can't afford to pass
+that by. If we have fallen down we want to know how, as well as to
+catch the burglar."
+
+"How are the signals given?" I asked.
+
+"Well, when the day's business is over, for instance, Schloss would
+swing the heavy safe doors together and over them place the doors of a
+wooden cabinet. That signals an alarm to us here. We answer it and if
+the proper signal is returned, all right. After that no one can tamper
+with the safe later in the night without sounding an alarm that would
+bring a quick investigation."
+
+"But suppose that it became necessary to open the safe before the next
+morning. Might not some trusted employee return to the office, open it,
+give the proper signals and loot the safe?"
+
+"No indeed," he answered confidently. "The very moment anyone touches
+the cabinet, the alarm is sounded. Even if the proper code signal is
+returned, it is not sufficient. A couple of our trusted men from the
+central office hustle around there anyhow and they don't leave until
+they are satisfied that everything is right. We have the authorized
+signatures on hand of those who are supposed to open the safe and a
+duplicate of one of them must be given or there is an arrest."
+
+McLear considered for a moment.
+
+"For instance, Schloss, like all the rest, was assigned a box in which
+was deposited a sealed envelope containing a key to the office and his
+own signature, in this case, since he alone knew the combination. Now,
+when an alarm is sounded, as it was last night, and the key removed to
+gain entrance to the office, a record is made and the key has to be
+sealed up again by Schloss. A report is also submitted showing when the
+signals are received and anything else that is worth recording. Last
+night our men found nothing wrong, apparently. But this morning we
+learn of the robbery."
+
+"The point is, then," ruminated Kennedy, "what happened in the interval
+between the ringing of the alarm and the arrival of the special
+officers? I think I'll drop around and look Schloss' place over," he
+added quietly, evidently eager to begin at the actual scene of the
+crime.
+
+On the door of the office to which McLear took us was one of those
+small blue plates which chance visitors to Maiden Lane must have seen
+often. To the initiated--be he crook or jeweler--this simple sign means
+that the merchant is a member of the Jewelers' Security Alliance,
+enough in itself, it would seem, to make the boldest burglar hesitate.
+For it is the motto of this organization to "get" the thief at any cost
+and at any time. Still, it had not deterred the burglar in this
+instance.
+
+"I know people are going to think it is a fake burglary," exclaimed
+Schloss, a stout, prosperous-looking gem broker, as we introduced
+ourselves. "But over two hundred thousands dollars' worth of stones are
+gone," he half groaned. "Think of it, man," he added, "one of the
+greatest robberies since the Dead Line was established. And if they can
+get away with it, why, no one down here is protected any more. Half a
+billion dollars in jewels in Maiden Lane and John Street are easy prey
+for the cracksmen!"
+
+Staggering though the loss must have been to him, he had apparently
+recovered from the first shock of the discovery and had begun the fight
+to get back what had been lost.
+
+It was, as McLear had intimated, a most amazing burglary, too. The door
+of Schloss' safe was open when Kennedy and I arrived and found the
+excited jeweler nervously pacing the office. Surrounding the safe, I
+noticed a wooden framework constructed in such a way as to be a part of
+the decorative scheme of the office.
+
+Schloss banged the heavy doors shut.
+
+"There, that's just how it was--shut as tight as a drum. There was
+absolutely no mark of anyone tampering with the combination lock. And
+yet the safe was looted!"
+
+"How did you discover it?" asked Craig. "I presume you carry burglary
+insurance?"
+
+Schloss looked up quickly. "That's what I expected as a first question.
+No, I carried very little insurance. You see, I thought the safe, one
+of those new chrome steel affairs, was about impregnable. I never lost
+a moment's sleep over it; didn't think it possible for anyone to get
+into it. For, as you see, it is completely wired by the Hale Electric
+Protection--that wooden framework about it. No one could touch that
+when it was set without jangling a bell at the central office which
+would send men scurrying here to protect the place."
+
+"But they must have got past it," suggested Kennedy.
+
+"Yes--they must have. At least this morning I received the regular Hale
+report. It said that their wires registered last night as though some
+one was tampering with the safe. But by the time they got around, in
+less than five minutes, there was no one here, nothing seemed to be
+disturbed. So they set it down to induction or electrolysis, or
+something the matter with the wires. I got the report the first thing
+when I arrived here with my assistant, Muller."
+
+Kennedy was on his knees, going over the safe with a fine brush and
+some powder, looking now and then through a small magnifying glass.
+
+"Not a finger print," he muttered. "The cracksman must have worn
+gloves. But how did he get in? There isn't a mark of 'soup' having been
+used to blow it up, nor of a 'can-opener' to rip it open, if that were
+possible, nor of an electric or any other kind of drill."
+
+"I've read of those fellows who burn their way in," said Schloss.
+
+"But there is no hole," objected Kennedy, "not a trace of the use of
+thermit to burn the way in or of the oxyacetylene blowpipe to cut a
+piece out. Most extraordinary," he murmured.
+
+"You see," shrugged Schloss, "everyone will say it must have been
+opened by one who knew the combination. But I am the only one. I have
+never written it down or told anyone, not even Muller. You understand
+what I am up against?"
+
+"There's the touch system," I suggested. "You remember, Craig, the old
+fellow who used to file his finger tips to the quick until they were so
+sensitive that he could actually feel when he had turned the
+combination to the right plunger? Might not that explain the lack of
+finger prints also?" I added eagerly.
+
+"Nothing like that in this case, Walter," objected Craig positively.
+"This fellow wore gloves, all right. No, this safe has been opened and
+looted by no ordinarily known method. It's the most amazing case I ever
+saw in that respect--almost as if we had a cracksman in the fourth
+dimension to whom the inside of a closed cube is as accessible as is
+the inside of a plane square to us three dimensional creatures. It is
+almost incomprehensible."
+
+I fancied I saw Schloss' face brighten as Kennedy took this view. So
+far, evidently, he had run across only skepticism.
+
+"The stones were unset?" resumed Craig.
+
+"Mostly. Not all."
+
+"You would recognize some of them if you saw them?"
+
+"Yes indeed. Some could be changed only by re-cutting. Even some of
+those that were set were of odd cut and size--some from a diamond
+necklace which belonged to a--"
+
+There was something peculiar in both his tone and manner as he cut
+short the words.
+
+"To whom?" asked Kennedy casually.
+
+"Oh, once to a well-known woman in society," he said carefully. "It is
+mine, though, now--at least it was mine. I should prefer to mention no
+names. I will give a description of the stones."
+
+"Mrs. Lynn Moulton, for instance?" suggested Craig quietly.
+
+Schloss jumped almost as if a burglar alarm had sounded under his very
+ears. "How did you know? Yes--but it was a secret. I made a large loan
+on it, and the time has expired."
+
+"Why did she need money so badly?" asked Kennedy.
+
+"How should I know?" demanded Schloss.
+
+Here was a deepening mystery, not to be elucidated by continuing this
+line of inquiry with Schloss, it seemed.
+
+
+
+
+CHAPTER XVII
+
+THE PASTE REPLICA
+
+
+Carefully Craig was going over the office. Outside of the safe, there
+had apparently been nothing of value. The rest of the office was not
+even wired, and it seemed to have been Schloss' idea that the few
+thousands of burglary insurance amply protected him against such loss.
+As for the safe, its own strength and the careful wiring might well
+have been considered quite sufficient under any hitherto to-be-foreseen
+circumstances.
+
+A glass door, around the bend of a partition, opened from the hallway
+into the office and had apparently been designed with the object of
+making visible the safe so that anyone passing might see whether an
+intruder was tampering with it.
+
+Kennedy had examined the door, perhaps in the expectation of finding
+finger prints there, and was passing on to other things, when a change
+in his position caused his eye to catch a large oval smudge on the
+glass, which was visible when the light struck it at the right angle.
+Quickly he dusted it over with the powder, and brought out the detail
+more clearly. As I examined it, while Craig made preparations to cut
+out the glass to preserve it, it seemed to contain a number of minute
+points and several more or less broken parallel lines. The edges
+gradually trailed off into an indistinct faintness.
+
+Business, naturally, was at a standstill, and as we were working near
+the door, we could see that the news of Schloss' strange robbery had
+leaked out and was spreading rapidly. Scores of acquaintances in the
+trade stopped at the door to inquire about the rumor.
+
+To each, it seemed that Morris Muller, the working jeweler employed by
+Schloss, repeated the same story.
+
+"Oh," he said, "it is a big loss--yes--but big as it is, it will not
+break Mr. Schloss. And," he would add with the tradesman's idea of
+humor, "I guess he has enough to play a game of poker--eh?"
+
+"Poker?" asked Kennedy smiling. "Is he much of a player?"
+
+"Yes. Nearly every night with his friends he plays."
+
+Kennedy made a mental note of it. Evidently Schloss trusted Muller
+implicitly. He seemed like a partner, rather than an employee, even
+though he had not been entrusted with the secret combination.
+
+Outside, we ran into city detective Lieutenant Winters, the officer who
+was stationed at the Maiden Lane post, guarding that famous section of
+the Dead Line established by the immortal Byrnes at Fulton Street,
+below which no crook was supposed to dare even to be seen. Winters had
+been detailed on the case.
+
+"You have seen the safe in there?" asked Kennedy, as he was leaving to
+carry on his investigation elsewhere.
+
+Winters seemed to be quite as skeptical as Schloss had intimated the
+public would be. "Yes," he replied, "there's been an epidemic of
+robbery with the dull times--people who want to collect their burglary
+insurance, I guess."
+
+"But," objected Kennedy, "Schloss carried so little."
+
+"Well, there was the Hale Protection. How about that?"
+
+Craig looked up quickly, unruffled by the patronizing air of the
+professional toward the amateur detective.
+
+"What is your theory?" he asked. "Do you think he robbed himself?"
+
+Winters shrugged his shoulders. "I've been interested in Schloss for
+some time," he said enigmatically. "He has had some pretty swell
+customers. I'll keep you wised up, if anything happens," he added in a
+burst of graciousness, walking off.
+
+On the way to the subway, we paused again to see McLear.
+
+"Well," he asked, "what do you think of it, now?"
+
+"All most extraordinary," ruminated Craig. "And the queerest feature of
+all is that the chief loss consists of a diamond necklace that belonged
+once to Mrs. Antoinette Moulton."
+
+"Mrs. Lynn Moulton?" repeated McLear.
+
+"The same," assured Kennedy.
+
+McLear appeared somewhat puzzled. "Her husband is one of our old
+subscribers," he pursued. "He is a lawyer on Wall Street and quite a
+gem collector. Last night his safe was tampered with, but this morning
+he reports no loss. Not half an hour ago he had us on the wire
+congratulating us on scaring off the burglars, if there had been any."
+
+"What is your opinion," I asked. "Is there a gang operating?"
+
+"My belief is," he answered, reminiscently of his days on the detective
+force, "that none of the loot will be recovered until they start to
+'fence' it. That would be my lay--to look for the fence. Why, think of
+all the big robberies that have been pulled off lately. Remember," he
+went on, "the spoils of a burglary consist generally of precious
+stones. They are not currency. They must be turned into currency--or
+what's the use of robbery?
+
+"But merely to offer them for sale at an ordinary jeweler's would be
+suspicious. Even pawnbrokers are on the watch. You see what I am
+driving at? I think there is a man or a group of men whose business it
+is to pay cash for stolen property and who have ways of returning gems
+into the regular trade channels. In all these robberies we get a
+glimpse of as dark and mysterious a criminal as has ever been recorded.
+He may be--anybody. About his legitimacy, I believe, no question has
+ever been raised. And, I tell you, his arrest is going to create a
+greater sensation than even the remarkable series of robberies that he
+has planned or made possible. The question is, to my mind, who is this
+fence?"
+
+McLear's telephone rang and he handed the instrument to Craig.
+
+"Yes, this is Professor Kennedy," answered Craig. "Oh, too bad you've
+had to try all over to get me. I've been going from one place to
+another gathering clues and have made good progress, considering I've
+hardly started. Why--what's the matter? Really?"
+
+An interval followed, during which McLear left to answer a personal
+call on another wire.
+
+As Kennedy hung up the receiver, his face wore a peculiar look. "It was
+Mrs. Moulton," he blurted out. "She thinks that her husband has found
+out that the necklace is paste."
+
+"How?" I asked.
+
+"The paste replica is gone from her wall safe in the Deluxe."
+
+I turned, startled at the information. Even Kennedy himself was
+perplexed at the sudden succession of events. I had nothing to say.
+
+Evidently, however, his rule was when in doubt play a trump, for,
+twenty minutes later found us in the office of Lynn Moulton, the famous
+corporation lawyer, in Wall Street.
+
+Moulton was a handsome man of past fifty with a youthful face against
+his iron gray hair and mustache, well dressed, genial, a man who seemed
+keenly in love with the good things of life.
+
+"It is rumored," began Kennedy, "that an attempt was made on your safe
+here at the office last night."
+
+"Yes," he admitted, taking off his glasses and polishing them
+carefully. "I suppose there is no need of concealment, especially as I
+hear that a somewhat similar attempt was made on the safe of my friend
+Herman Schloss in Maiden Lane."
+
+"You lost nothing?"
+
+Moulton put his glasses on and looked Kennedy in the face frankly.
+
+"Nothing, fortunately," he said, then went on slowly. "You see, in my
+later years, I have been something of a collector of precious stones
+myself. I don't wear them, but I have always taken the keenest pleasure
+in owning them and when I was married it gave me a great deal more
+pleasure to have them set in rings, pendants, tiaras, necklaces, and
+other forms for my wife."
+
+He had risen, with the air of a busy man who had given the subject all
+the consideration he could afford and whose work proceeded almost by
+schedule. "This morning I found my safe tampered with, but, as I said,
+fortunately something must have scared off the burglars."
+
+He bowed us out politely. What was the explanation, I wondered. It
+seemed, on the face of things, that Antoinette Moulton feared her
+husband. Did he know something else already, and did she know he knew?
+To all appearances he took it very calmly, if he did know. Perhaps that
+was what she feared, his very calmness.
+
+"I must see Mrs. Moulton again," remarked Kennedy, as we left.
+
+The Moultons lived, we found, in one of the largest suites of a new
+apartment hotel, the Deluxe, and in spite of the fact that our arrival
+had been announced some minutes before we saw Mrs. Moulton, it was
+evident that she had been crying hysterically over the loss of the
+paste jewels and what it implied.
+
+"I missed it this morning, after my return from seeing you," she
+replied in answer to Craig's inquiry, then added, wide-eyed with alarm,
+"What shall I do? He must have opened the wall safe and found the
+replica. I don't dare ask him point-blank."
+
+"Are you sure he did it?" asked Kennedy, more, I felt, for its moral
+effect on her than through any doubt in his own mind.
+
+"Not sure. But then the wall safe shows no marks, and the replica is
+gone."
+
+"Might I see your jewel case?" he asked.
+
+"Surely. I'll get it. The wall safe is in Lynn's room. I shall probably
+have to fuss a long time with the combination."
+
+In fact she could not have been very familiar with it for it took
+several minutes before she returned. Meanwhile, Kennedy, who had been
+drumming absently on the arms of his chair, suddenly rose and walked
+quietly over to a scrap basket that stood beside an escritoire. It had
+evidently just been emptied, for the rooms must have been cleaned
+several hours before. He bent down over it and picked up two scraps of
+paper adhering to the wicker work. The rest had evidently been thrown
+away.
+
+I bent over to read them. One was:
+
+ --rest Nettie--
+ --dying to see--
+
+The other read:
+
+ --cherche to-d
+ --love and ma
+ --rman.
+
+What did it mean? Hastily, I could fill in "Dearest Nettie," and "I am
+dying to see you." Kennedy added, "The Recherche to-day," that being
+the name of a new apartment uptown, as well as "love and many kisses."
+But "--rman"--what did that mean? Could it be Herman--Herman Schloss?
+
+She was returning and we resumed our seats quickly.
+
+Kennedy took the jewel case from her and examined it carefully. There
+was not a mark on it.
+
+"Mrs. Moulton," he said slowly, rising and handing it back to her,
+"have you told me all?"
+
+"Why--yes," she answered.
+
+Kennedy shook his head gravely.
+
+"I'm afraid not. You must tell me everything."
+
+"No--no," she cried vehemently, "there is nothing more."
+
+We left and outside the Deluxe he paused, looked about, caught sight of
+a taxicab and hailed it.
+
+"Where?" asked the driver.
+
+"Across the street," he said, "and wait. Put the window in back of you
+down so I can talk. I'll tell you where to go presently. Now, Walter,
+sit back as far as you can. This may seem like an underhand thing to
+do, but we've got to get what that woman won't tell us or give up the
+case."
+
+Perhaps half an hour we waited, still puzzling over the scraps of
+paper. Suddenly I felt a nudge from Kennedy. Antoinette Moulton was
+standing in the doorway across the street. Evidently she preferred not
+to ride in her own car, for a moment later she entered a taxicab.
+
+"Follow that black cab," said Kennedy to our driver.
+
+Sure enough, it stopped in front of the Recherche Apartments and Mrs.
+Moulton stepped out and almost ran in.
+
+We waited a moment, then Kennedy followed. The elevator that had taken
+her up had just returned to the ground floor.
+
+"The same floor again," remarked Kennedy, jauntily stepping in and
+nodding familiarly to the elevator boy.
+
+Then he paused suddenly, looked at his watch, fixed his gaze
+thoughtfully on me an instant, and exclaimed. "By George--no. I can't
+go up yet. I clean forgot that engagement at the hotel. One moment,
+son. Let us out. We'll be back again."
+
+Considerably mystified, I followed him to the sidewalk.
+
+"You're entitled to an explanation," he laughed catching my bewildered
+look as he opened the cab door. "I didn't want to go up now while she
+is there, but I wanted to get on good terms with that boy. We'll wait
+until she comes down, then go up."
+
+"Where?" I asked.
+
+"That's what I am going through all this elaborate preparation to find
+out. I have no more idea than you have."
+
+It could not have been more than twenty minutes later when Mrs. Moulton
+emerged rather hurriedly, and drove away.
+
+While we had been waiting I had observed a man on the other side of the
+street who seemed unduly interested in the Recherche, too, for he had
+walked up and down the block no less than six times. Kennedy saw him,
+and as he made no effort to follow Mrs. Moulton, Kennedy did not do so
+either. In fact a little quick glance which she had given at our cab
+had raised a fear that she might have discovered that she was being
+followed.
+
+Kennedy and I paid off our cabman and sauntered into the Recherche in
+the most debonair manner we could assume.
+
+"Now, son, we'll go up," he said to the boy who, remembering us, and
+now not at all clear in his mind that he might not have seen us before
+that, whisked us to the tenth floor.
+
+"Let me see," said Kennedy, "it's number one hundred and--er---"
+
+"Three," prompted the boy.
+
+He pressed the buzzer and a neatly dressed colored maid responded.
+
+"I had an appointment here with Mrs. Moulton this morning," remarked
+Kennedy.
+
+"She has just gone," replied the maid, off her guard.
+
+"And was to meet Mr. Schloss here in half an hour," he added quickly.
+
+It was the maid's turn to look surprised.
+
+"I didn't think he was to be here," she said. "He's had some--"
+
+"Trouble at the office," supplied Kennedy. "That's what it was about.
+Perhaps he hasn't been able to get away yet. But I had the appointment.
+Ah, I see a telephone in the hall. May I?"
+
+He had stepped politely in, and by dint of cleverly keeping his finger
+on the hook in the half light, he carried on a one-sided conversation
+with himself long enough to get a good chance to look about.
+
+There was an air of quiet and refinement about the apartment in the
+Recherche. It was darkened to give the little glowing electric bulbs in
+their silken shades a full chance to simulate right. The deep velvety
+carpets were noiseless to the foot, and the draperies, the pictures,
+the bronzes, all bespoke taste.
+
+But the chief objects of interest to Craig were the little square green
+baize-covered tables on one of which lay neatly stacked a pile of
+gilt-edged cards and a mahogany box full of ivory chips of red, white
+and blue.
+
+It was none of the old-time gambling places, like Danfield's, with its
+steel door which Craig had once cut through with an oxyacetylene
+blowpipe in order to rescue a young spendthrift from himself.
+
+Kennedy seemed perfectly well satisfied merely with a cursory view of
+the place, as he hung up the receiver and thanked the maid politely for
+allowing him to use it.
+
+"This is up-to-date gambling in cleaned-up New York," he remarked as we
+waited for the elevator to return for us. "And the worst of it all is
+that it gets the women as well as the men. Once they are caught in the
+net, they are the most powerful lure to men that the gamblers have yet
+devised."
+
+We rode down in silence, and as we went down the steps to the street, I
+noticed the man whom we had seen watching the place, lurking down at
+the lower corner. Kennedy quickened his pace and came up behind him.
+
+"Why, Winters!" exclaimed Craig. "You here?"
+
+"I might say the same to you," grinned the detective not displeased
+evidently that our trail had crossed his. "I suppose you are looking
+for Schloss, too. He's up in the Recherche a great deal, playing poker.
+I understand he owns an interest in the game up there."
+
+Kennedy nodded, but said nothing.
+
+"I just saw one of the cappers for the place go out before you went in."
+
+"Capper?" repeated Kennedy surprised. "Antoinette Moulton a steerer for
+a gambling joint? What can a rich society woman have to do with a place
+like that or a man like Schloss?"
+
+Winters smiled sardonically. "Society ladies to-day often get into
+scrapes of which their husbands know nothing," he remarked. "You didn't
+know before that Antoinette Moulton, like many of her friends in the
+smart set, was a gambler--and loser--did you?"
+
+Craig shook his head. He had more of human than scientific interest in
+a case of a woman of her caliber gone wrong.
+
+"But you must have read of the famous Moulton diamonds?"
+
+"Yes," said Craig, blankly, as if it were all news to him.
+
+"Schloss has them--or at least had them. The jewels she wore at the
+opera this winter were paste, I understand."
+
+"Does Moulton play?" he asked.
+
+"I think so--but not here, naturally. In a way, I suppose, it is his
+fault. They all do it. The example of one drives on another."
+
+Instantly there flashed over my mind a host of possibilities. Perhaps,
+after all, Winters had been right. Schloss had taken this way to make
+sure of the jewels so that she could not redeem them. Suddenly another
+explanation crowded that out. Had Mrs. Moulton robbed the safe herself,
+or hired some one else to do it for her, and had that person gone back
+on her?
+
+Then a horrid possibility occurred to me. Whatever Antoinette Moulton
+may have been and done, some one must have her in his power. What a
+situation for the woman! My sympathy went out to her in her supreme
+struggle. Even if it had been a real robbery, Schloss might easily
+recover from it. But for her every event spelled ruin and seemed only
+to be bringing that ruin closer.
+
+We left Winters, still watching on the trail of Schloss, and went on
+uptown to the laboratory.
+
+
+
+
+CHAPTER XVIII
+
+THE BURGLAR'S MICROPHONE
+
+
+That night I was sitting, brooding over the case, while Craig was
+studying a photograph which he made of the smudge on the glass door
+down at Schloss'. He paused in his scrutiny of the print to answer the
+telephone.
+
+"Something has happened to Schloss," he exclaimed seizing his hat and
+coat. "Winters has been watching him. He didn't go to the Recherche.
+Winters wants me to meet him at a place several blocks below it Come
+on. He wouldn't say over the wire what it was. Hurry."
+
+We met Winters in less than ten minutes at the address he had given, a
+bachelor apartment in the neighborhood of the Recherche.
+
+"Schloss kept rooms here," explained Winters, hurrying us quickly
+upstairs. "I wanted you to see before anyone else."
+
+As we entered the large and luxuriously furnished living room of the
+jeweler's suite, a gruesome sight greeted us.
+
+There lay Schloss on the floor, face down, in a horribly contorted
+position. In one hand, clenched under him partly, the torn sleeve of a
+woman's dress was grasped convulsively. The room bore unmistakable
+traces of a violent struggle, but except for the hideous object on the
+floor was vacant.
+
+Kennedy bent down over him. Schloss was dead. In a corner, by the door,
+stood a pile of grips, stacked up, packed, and undisturbed.
+
+Winters who had been studying the room while we got our bearings picked
+up a queer-looking revolver from the floor. As he held it up I could
+see that along the top of the barrel was a long cylinder with a ratchet
+or catch at the butt end. He turned it over and over carefully.
+
+"By George," he muttered, "it has been fired off."
+
+Kennedy glanced more minutely at the body. There was not a mark on it.
+I stared about vacantly at the place where Winters had picked the thing
+up.
+
+"Look," I cried, my eye catching a little hole in the baseboard of the
+woodwork near it.
+
+"It must have fallen and exploded on the floor," remarked Kennedy. "Let
+me see it, Winters."
+
+Craig held it at arm's length and pulled the catch. Instead of an
+explosion, there came a cone of light from the top of the gun. As
+Kennedy moved it over the wall, I saw in the center of the circle of
+light a dark spot.
+
+"A new invention," Craig explained. "All you need to do is to move it
+so that little dark spot falls directly on an object. Pull the
+trigger--the bullet strikes the dark spot. Even a nervous and unskilled
+marksman becomes a good shot in the dark. He can even shoot from behind
+the protection of something--and hit accurately."
+
+It was too much for me. I could only stand and watch Kennedy as he
+deftly bent over Schloss again and placed a piece of chemically
+prepared paper flat on the forehead of the dead man.
+
+When he withdrew it, I could see that it bore marks of the lines on his
+head. Without a word, Kennedy drew from his pocket a print of the
+photograph of the smudge on Schloss' door.
+
+"It is possible," he said, half to himself, "to identify a person by
+means of the arrangement of the sweat glands or pores. Poroscopy, Dr.
+Edmond Locard, director of the Police Laboratory at Lyons, calls it.
+The shape, arrangement, number per square centimeter, all vary in
+different individuals. Besides, here we have added the lines of the
+forehead."
+
+He was studying the two impressions intensely. When he looked up from
+his examination, his face wore a peculiar expression.
+
+"This is not the head which was placed so close to the glass of the
+door of Schloss' office, peering through, on the night of the robbery,
+in order to see before picking the lock whether the office was empty
+and everything ready for the hasty attack on the safe."
+
+"That disposes of my theory that Schloss robbed himself," remarked
+Winters reluctantly. "But the struggle here, the sleeve of the dress,
+the pistol--could he have been shot?"
+
+"No, I think not," considered Kennedy. "It looks to me more like a case
+of apoplexy."
+
+"What shall we do?" asked Winters. "Far from clearing anything up, this
+complicates it."
+
+"Where's Muller?" asked Kennedy. "Does he know? Perhaps he can shed
+some light on it."
+
+The clang of an ambulance bell outside told that the aid summoned by
+Winters had arrived.
+
+We left the body in charge of the surgeon and of a policeman who
+arrived about the same time, and followed Winters.
+
+Muller lived in a cheap boarding house in a shabbily respectable street
+downtown, and without announcing ourselves we climbed the stairs to his
+room. He looked up surprised but not disconcerted as we entered.
+
+"What's the matter?" he asked.
+
+"Muller," shot out Winters, "we have just found Mr. Schloss dead!"
+
+"D-dead!" he stammered.
+
+The man seemed speechless with horror.
+
+"Yes, and with his grips packed as if to run away."
+
+Muller looked dazedly from one of us to the other, but shut up like a
+clam.
+
+"I think you had better come along with us as a material witness,"
+burst out Winters roughly.
+
+Kennedy said nothing, leaving that sort of third degree work to the
+detective. But he was not idle, as Winters tried to extract more than
+the monosyllables, "I don't know," in answer to every inquiry of Muller
+about his employer's life and business.
+
+A low exclamation from Craig attracted my attention from Winters. In a
+corner he had discovered a small box and had opened it. Inside was a
+dry battery and a most peculiar instrument, something like a little
+flat telephone transmitter yet attached by wires to earpieces that
+fitted over the head after the manner of those of a wireless detector.
+
+"What's this?" asked Kennedy, dangling it before Muller.
+
+He looked at it phlegmatically. "A deaf instrument I have been working
+on," replied the jeweler. "My hearing is getting poor."
+
+Kennedy looked hastily from the instrument to the man.
+
+"I think I'll take it along with us," he said quietly.
+
+Winters, true to his instincts, had been searching Muller in the
+meantime. Besides the various assortment that a man carries in his
+pockets usually, including pens, pencils, notebooks, a watch, a
+handkerchief, a bunch of keys, one of which was large enough to open a
+castle, there was a bunch of blank and unissued pawn-tickets bearing
+the name, "Stein's One Per Cent. a Month Loans," and an address on the
+Bowery.
+
+Was Muller the "fence" we were seeking, or only a tool for the "fence"
+higher up? Who was this Stein?
+
+What it all meant I could only guess. It was a far cry from the wealth
+of Diamond Lane to a dingy Bowery pawnshop, even though pawnbroking at
+one per cent. a month--and more, on the side--pays. I knew, too, that
+diamonds are hoarded on the East Side as nowhere else in the world,
+outside of India. It was no uncommon thing, I had heard, for a
+pawnbroker whose shop seemed dirty and greasy to the casual visitor to
+have stored away in his vault gems running into the hundreds of
+thousands of dollars.
+
+"Mrs. Moulton must know of this," remarked Kennedy. "Winters, you and
+Jameson bring Muller along. I am going up to the Deluxe."
+
+I must say that I was surprised at finding Mrs. Moulton there. Outside
+the suite Winters and I waited with the unresisting Muller, while
+Kennedy entered. But through the door which he left ajar I could hear
+what passed.
+
+"Mrs. Moulton," he began, "something terrible has happened--"
+
+He broke off, and I gathered that her pale face and agitated manner
+told him that she knew already.
+
+"Where is Mr. Moulton?" he went on, changing his question.
+
+"Mr. Moulton is at his office," she answered tremulously. "He
+telephoned while I was out that he had to work to-night. Oh, Mr.
+Kennedy--he knows--he knows. I know it. He has avoided me ever since I
+missed the replica from-"
+
+"Sh!" cautioned Craig. He had risen and gone to the door.
+
+"Winters," he whispered, "I want you to go down to Lynn Moulton's
+office. Meanwhile Jameson can take care of Muller. I am going over to
+that place of Stein's presently. Bring Moulton up there. You will wait
+here, Walter, for the present," he nodded.
+
+He returned to the room where I could hear her crying softly.
+
+"Now, Mrs. Moulton," he said gently, "I'm afraid I must trouble you to
+go with me. I am going over to a pawnbroker's on the Bowery."
+
+"The Bowery?" she repeated, with a genuinely surprised shudder. "Oh,
+no, Mr. Kennedy. Don't ask me to go anywhere to-night. I am--I am in no
+condition to go anywhere--to do anything--I--"
+
+"But you must," said Kennedy in a low voice.
+
+"I can't. Oh--have mercy on me. I am terribly upset. You--"
+
+"It is your duty to go, Mrs. Moulton," he repeated.
+
+"I don't understand." she murmured. "A pawnbroker's?"
+
+"Come," urged Kennedy, not harshly but firmly, then, as she held back,
+added, playing a trump card, "We must work quickly. In his hands we
+found the fragments of a torn dress. When the police--"
+
+She uttered a shriek. A glance had told her, if she had deceived
+herself before, that Kennedy knew her secret.
+
+Antoinette Moulton was standing before him, talking rapidly.
+
+"Some one has told Lynn. I know it. There is nothing now that I can
+conceal. If you had come half an hour later you would not have found
+me. He had written to Mr. Schloss, threatening him that if he did not
+leave the country he would shoot him at sight. Mr. Schloss showed me
+the letter.
+
+"It had come to this. I must either elope with Schloss, or lose his
+aid. The thought of either was unendurable. I hated him--yet was
+dependent on him.
+
+"To-night I met him, in his empty apartment, alone. I knew that he had
+what was left of his money with him, that everything was packed up. I
+went prepared. I would not elope. My plan was no less than to make him
+pay the balance on the necklace that he had lost--or to murder him.
+
+"I carried a new pistol in my muff, one which Lynn had just bought. I
+don't know how I did it. I was desperate.
+
+"He told me he loved me, that Lynn did not, never had--that Lynn had
+married me only to show off his wealth and diamonds, to give him a
+social! position--that I was merely a--a piece of property--a dummy.
+
+"He tried to kiss me. It was revolting. I struggled away from him.
+
+"And in the struggle, the revolver fell from my muff and exploded on
+the floor.
+
+"At once he was aflame with suspicion.
+
+"'So--it's murder you want!' he shouted. 'Well, murder it shall be!'
+
+"I saw death in his eye as he seized my arm. I was defenseless now. The
+old passion came over him. Before he killed--he--would have his way
+with me.
+
+"I screamed. With a wild effort I twisted away from him.
+
+"He raised his hand to strike me, I saw his eyes, glassy. Then he sank
+back--fell to the floor--dead of apoplexy--dead of his furious emotions.
+
+"I fled.
+
+"And now you have found me."
+
+She had turned, hastily, to leave the room. Kennedy blocked the door.
+
+"Mrs. Moulton," he said firmly, "listen to me. What was the first
+question you asked me? 'Can I trust you?' And I told you you could.
+This is no time for--for suicide." He shot the word out bluntly. "All
+may not be lost. I have sent for your husband. Muller is outside."
+
+"Muller?" she cried. "He made the replica."
+
+"Very well. I am going to clear this thing up. Come. You MUST."
+
+It was all confused to me, the dash in a car to the little pawnbroker's
+on the first floor of a five-story tenement, the quick entry into the
+place by one of Muller's keys.
+
+Over the safe in back was a framework like that which had covered
+Schloss' safe. Kennedy tore it away, regardless of the alarm which it
+must have sounded. In a moment he was down before it on his knees.
+
+"This is how Schloss' safe was opened so quickly," he muttered, working
+feverishly. "Here is some of their own medicine."
+
+He had placed the peculiar telephone-like transmitter close to the
+combination lock and was turning the combination rapidly.
+
+Suddenly he rose, gave the bolts a twist, and the ponderous doors swung
+open.
+
+"What is it?" I asked eagerly.
+
+"A burglar's microphone," he answered, hastily looking over the
+contents of the safe. "The microphone is now used by burglars for
+picking combination locks. When you turn the lock, a slight sound is
+made when the proper number comes opposite the working point. It can be
+heard sometimes by a sensitive ear, although it is imperceptible to
+most persons. But by using a microphone it is an easy matter to hear
+the sounds which allow of opening the lock."
+
+He had taken a yellow chamois bag out of the safe and opened it.
+
+Inside sparkled the famous Moulton diamonds. He held them up--in all
+their wicked brilliancy. No one spoke.
+
+Then he took another yellow bag, more dirty and worn than the first. As
+he opened it, Mrs. Moulton could restrain herself no longer.
+
+"The replica!" she cried. "The replica!"
+
+Without a word, Craig handed the real necklace to her. Then he slipped
+the paste jewels into the newer of the bags and restored both it and
+the empty one to their places, banged shut the door of the safe, and
+replaced the wooden screen.
+
+"Quick!" he said to her, "you have still a minute to get away.
+Hurry--anywhere--away--only away!"
+
+The look of gratitude that came over her face, as she understood the
+full meaning of it was such as I had never seen before.
+
+"Quick!" he repeated.
+
+It was too late.
+
+"For God's sake, Kennedy," shouted a voice at the street door, "what
+are you doing here?"
+
+It was McLear himself. He had come with the Hale patrol, on his mettle
+now to take care of the epidemic of robberies.
+
+Before Craig could reply a cab drew up with a rush at the curb and two
+men, half fighting, half cursing, catapulted themselves into the shop.
+
+They were Winters and Moulton.
+
+Without a word, taking advantage of the first shock of surprise,
+Kennedy had clapped a piece of chemical paper on the foreheads of Mrs.
+Moulton, then of Moulton, and on Muller's. Oblivious to the rest of us,
+he studied the impressions in the full light of the counter.
+
+Moulton was facing his wife with a scornful curl of the lip.
+
+"I've been told of the paste replica--and I wrote Schloss that I'd
+shoot him down like the dog he is, you--you traitress," he hissed.
+
+She drew herself up scornfully.
+
+"And I have been told why you married me--to show off your wicked
+jewels and help you in your--"
+
+"You lie!" he cried fiercely. "Muller--some one--open this
+safe--whosever it is. If what I have been told is true, there is in it
+one new bag containing the necklace. It was stolen from Schloss to whom
+you sold my jewels. The other old bag, stolen from me, contains the
+paste replica you had made to deceive me."
+
+It was all so confused that I do not know how it happened. I think it
+was Muller who opened the safe.
+
+"There is the new yellow bag," cried Moulton, "from Schloss' own safe.
+Open it."
+
+McLear had taken it. He did so. There sparkled not the real gems, but
+the replica.
+
+"The devil!" Moulton exclaimed, breaking from Winters and seizing the
+old bag.
+
+He tore it open and--it was empty.
+
+"One moment," interrupted Kennedy, looking up quietly from the counter.
+"Seal that safe again, McLear. In it are the Schloss jewels and the
+products of half a dozen other robberies which the dupe Muller--or
+Stein, as you please--pulled off, some as a blind to conceal the real
+criminal. You may have shown him how to leave no finger prints, but you
+yourself have left what is just as good--your own forehead print.
+McLear--you were right. There's your criminal--Lynn Moulton,
+professional fence, the brains of the thing."
+
+
+
+
+CHAPTER XIX
+
+THE GERM LETTER
+
+
+Lynn Moulton made no fight and Kennedy did not pursue the case, for,
+with the rescue of Antoinette Moulton, his interest ceased.
+
+Blackmail takes various forms, and the Moulton affair was only one
+phase of it. It was not long before we had to meet a much stranger
+attempt.
+
+"Read the letter, Professor Kennedy. Then I will tell you the sequel."
+
+Mrs. Hunter Blake lay back in the cushions of her invalid chair in the
+sun parlor of the great Blake mansion on Riverside Drive, facing the
+Hudson with its continuous reel of maritime life framed against the
+green-hilled background of the Jersey shore.
+
+Her nurse, Miss Dora Sears, gently smoothed out the pillows and
+adjusted them so that the invalid could more easily watch us. Mrs.
+Blake, wealthy, known as a philanthropist, was not an old woman, but
+had been for years a great sufferer from rheumatism.
+
+I watched Miss Sears eagerly. Full-bosomed, fine of face and figure,
+she was something more than a nurse; she was a companion. She had
+bright, sparkling black eyes and an expression about her well-cut mouth
+which made one want to laugh with her. It seemed to say that the world
+was a huge joke and she invited you to enjoy the joke with her.
+
+Kennedy took the letter which Miss Sears proffered him, and as he did
+so I could not help noticing her full, plump forearm on which gleamed a
+handsome plain gold bracelet. He spread the letter out on a dainty
+wicker table in such a way that we both could see it.
+
+We had been summoned over the telephone to the Blake mansion by
+Reginald Blake, Mrs. Blake's eldest son. Reginald had been very
+reticent over the reason, but had seemed very anxious and insistent
+that Kennedy should come immediately.
+
+Craig read quickly and I followed him, fascinated by the letter from
+its very opening paragraph.
+
+"Dear Madam," it began. "Having received my diploma as doctor of
+medicine and bacteriology at Heidelberg in 1909, I came to the United
+States to study a most serious disease which is prevalent in several of
+the western mountain states."
+
+So far, I reflected, it looked like an ordinary appeal for aid. The
+next words, however, were queer: "I have four hundred persons of wealth
+on my list. Your name was--"
+
+Kennedy turned the page. On the next leaf of the letter sheet was
+pasted a strip of gelatine. The first page had adhered slightly to the
+gelatine.
+
+"Chosen by fate," went on the sentence ominously.
+
+"By opening this letter," I read, "you have liberated millions of the
+virulent bacteria of this disease. Without a doubt you are infected by
+this time, for no human body is impervious to them, and up to the
+present only one in one hundred has fully recovered after going through
+all its stages."
+
+I gasped. The gelatine had evidently been arranged so that when the two
+sheets were pulled apart, the germs would be thrown into the air about
+the person opening the letter. It was a very ingenious device.
+
+The letter continued, "I am happy to say, however, that I have a
+prophylactic which will destroy any number of these germs if used up to
+the ninth day. It is necessary only that you should place five thousand
+dollars in an envelope and leave it for me to be called for at the desk
+of the Prince Henry Hotel. When the messenger delivers the money to me,
+the prophylactic will be sent immediately.
+
+"First of all, take a match and burn this letter to avoid spreading the
+disease. Then change your clothes and burn the old ones. Enclosed you
+will find in a germ-proof envelope an exact copy of this letter. The
+room should then be thoroughly fumigated. Do not come into close
+contact with anyone near and dear to you until you have used the
+prophylactic. Tell no one. In case you do, the prophylactic will not be
+sent under any circumstances. Very truly yours, DR. HANS HOPF."
+
+"Blackmail!" exclaimed Kennedy, looking intently again at the gelatine
+on the second page, as I involuntarily backed away and held my breath.
+
+"Yes, I know," responded Mrs. Blake anxiously, "but is it true?"
+
+There could be no doubt from the tone of her voice that she more than
+half believed that it was true.
+
+"I cannot say--yet," replied Craig, still cautiously scanning the
+apparently innocent piece of gelatine on the original letter which Mrs.
+Blake had not destroyed. "I shall have to keep it and examine it."
+
+On the gelatine I could see a dark mass which evidently was supposed to
+contain the germs.
+
+"I opened the letter here in this room," she went on. "At first I
+thought nothing of it. But this morning, when Buster, my prize
+Pekinese, who had been with me, sitting on my lap at the time, and
+closer to the letter even than I was, when Buster was taken suddenly
+ill, I--well, I began to worry."
+
+She finished with a little nervous laugh, as people will to hide their
+real feelings.
+
+"I should like to see the dog," remarked Kennedy simply.
+
+"Miss Sears," asked her mistress, "will you get Buster, please?"
+
+The nurse left the room. No longer was there the laughing look on her
+face. This was serious business.
+
+A few minutes later she reappeared, carrying gingerly a small dog
+basket. Mrs. Blake lifted the lid. Inside was a beautiful little
+"Peke," and it was easy to see that Buster was indeed ill.
+
+"Who is your doctor?" asked Craig, considering.
+
+"Dr. Rae Wilson, a very well-known woman physician."
+
+Kennedy nodded recognition of the name. "What does she say?" he asked,
+observing the dog narrowly.
+
+"We haven't told anyone, outside, of it yet," replied Mrs. Blake. "In
+fact until Buster fell sick, I thought it was a hoax."
+
+"You haven't told anyone?"
+
+"Only Reginald and my daughter Betty. Betty is frantic--not with fear
+for herself, but with fear for me. No one can reassure her. In fact it
+was as much for her sake as anyone's that I sent for you. Reginald has
+tried to trace the thing down himself, but has not succeeded."
+
+She paused. The door opened and Reginald Blake entered. He was a young
+fellow, self confident and no doubt very efficient at the new dances,
+though scarcely fitted to rub elbows with a cold world which, outside
+of his own immediate circle, knew not the name of Blake. He stood for a
+moment regarding us through the smoke of his cigarette.
+
+"Tell me just what you have done," asked Kennedy of him as his mother
+introduced him, although he had done the talking for her over the
+telephone.
+
+"Done?" he drawled. "Why, as soon as mother told me of the letter, I
+left an envelope up at the Prince Henry, as it directed."
+
+"With the money?" put in Craig quickly.
+
+"Oh, no--just as a decoy."
+
+"Yes. What happened?"
+
+"Well, I waited around a long time. It was far along in the day when a
+woman appeared at the desk. I had instructed the clerk to be on the
+watch for anyone who asked for mail addressed to a Dr. Hopf. The clerk
+slammed the register. That was the signal. I moved up closer."
+
+"What did she look like?" asked Kennedy keenly.
+
+"I couldn't see her face. But she was beautifully dressed, with a long
+light flowing linen duster, a veil that hid her features and on her
+hands and arms a long pair of motoring doeskin gloves. By George, she
+was a winner--in general looks, though. Well, something about the
+clerk, I suppose, must have aroused her suspicions. For, a moment
+later, she was gone in the crowd. Evidently she had thought of the
+danger and had picked out a time when the lobby would be full and
+everybody busy. But she did not leave by the front entrance through
+which she entered. I concluded that she must have left by one of the
+side street carriage doors."
+
+"And she got away?"
+
+"Yes. I found that she asked one of the boys at the door to crank up a
+car standing at the curb. She slid into the seat, and was off in a
+minute."
+
+Kennedy said nothing. But I knew that he was making a mighty effort to
+restrain comment on the bungling amateur detective work of the son of
+our client.
+
+Reginald saw the look on his face. "Still," he hastened, "I got the
+number of the car. It was 200859 New York."
+
+"You have looked it up?" queried Kennedy quickly.
+
+"I didn't need to do it. A few minutes later Dr. Rae Wilson herself
+came out--storming like mad. Her car had been stolen at the very door
+of the hotel by this woman with the innocent aid of the hotel
+employees."
+
+Kennedy was evidently keenly interested. The mention of the stolen car
+had apparently at once suggested an idea to him.
+
+"Mrs. Blake," he said, as he rose to go, "I shall take this letter with
+me. Will you see that Buster is sent up to my laboratory immediately?"
+
+She nodded. It was evident that Buster was a great pet with her and
+that it was with difficulty she kept from smoothing his silky coat.
+
+"You--you won't hurt Buster?" she pleaded.
+
+"No. Trust me. More than that, if there is any possible way of
+untangling this mystery, I shall do it."
+
+Mrs. Blake looked rather than spoke her thanks. As we went downstairs,
+accompanied by Miss Sears, we could see in the music room a very
+interesting couple, chatting earnestly over the piano.
+
+Betty Blake, a slip of a girl in her first season, was dividing her
+attention between her visitor and the door by which we were passing.
+
+She rose as she heard us, leaving the young man standing alone at the
+piano. He was of an age perhaps a year or two older than Reginald
+Blake. It was evident that, whatever Miss Betty might think, he had
+eyes for no one else but the pretty debutante. He even seemed to be
+regarding Kennedy sullenly, as if he were a possible rival.
+
+"You--you don't think it is serious?" whispered Betty in an undertone,
+scarcely waiting to be introduced. She had evidently known of our
+visit, but had been unable to get away to be present upstairs.
+
+"Really, Miss Blake," reassured Kennedy, "I can't say. All I can do is
+to repeat what I have already said to your mother. Keep up a good heart
+and trust me to work it out."
+
+"Thank you," she murmured, and then, impulsively extending her small
+hand to Craig, she added, "Mr. Kennedy, if there is anything I can do
+to help you, I beg that you will call on me."
+
+"I shall not forget," he answered, relinquishing the hand reluctantly.
+Then, as she thanked him, and turned again to her guest, he added in a
+low tone to me, "A remarkable girl, Walter, a girl that can be depended
+on."
+
+We followed Miss Sears down the hall.
+
+"Who was that young man in the music room?" asked Kennedy, when we were
+out of earshot.
+
+"Duncan Baldwin," she answered. "A friend and bosom companion of
+Reginald."
+
+"He seems to think more of Betty than of her brother," Craig remarked
+dryly.
+
+Miss Sears smiled. "Sometimes, we think they are secretly engaged," she
+returned. We had almost reached the door. "By the way," she asked
+anxiously, "do you think there are any precautions that I should take
+for Mrs. Blake--and the rest?"
+
+"Hardly," answered Kennedy, after a moment's consideration, "as long as
+you have taken none in particular already. Still, I suppose it will do
+no harm to be as antiseptic as possible."
+
+"I shall try," she promised, her face showing that she considered the
+affair now in a much more serious light than she had before our visit.
+
+"And keep me informed of anything that turns up," added Kennedy handing
+her a card with the telephone number of the laboratory.
+
+As we left the Blake mansion, Kennedy remarked, "We must trace that car
+somehow--at least we must get someone working on that."
+
+Half an hour later we were in a towering office building on Liberty
+Street, the home of various kinds of insurance. Kennedy stopped before
+a door which bore the name, "Douglas Garwood: Insurance Adjuster."
+
+Briefly, Craig told the story of the stolen car, omitting the account
+of the dastardly method taken to blackmail Mrs. Blake. As he proceeded
+a light seemed to break on the face of Garwood, a heavyset man, whose
+very gaze was inquisitorial.
+
+"Yes, the theft has been reported to us already by Dr. Wilson herself,"
+he interrupted. "The car was insured in a company I represent."
+
+"I had hoped so," remarked Kennedy, "Do you know the woman?" he added,
+watching the insurance adjuster who had been listening intently as he
+told about the fair motor car thief.
+
+"Know her?" repeated Garwood emphatically. "Why, man, we have been so
+close to that woman that I feel almost intimate with her. The
+descriptions are those of a lady, well-dressed, and with a voice and
+manner that would carry her through any of the fashionable hotels,
+perhaps into society itself."
+
+"One of a gang of blackmailers, then," I hazarded.
+
+Garwood shrugged his shoulders. "Perhaps," he acquiesced. "It is
+automobile thieving that interests me, though. Why," he went on, rising
+excitedly, "the gangs of these thieves are getting away with half a
+million dollars' worth of high-priced cars every year. The police seem
+to be powerless to stop it. We appeal to them, but with no result. So,
+now we have taken things into our own hands."
+
+"What are you doing in this case?" asked Kennedy.
+
+"What the insurance companies have to do to recover stolen
+automobiles," Garwood replied. "For, with all deference to your friend,
+Deputy O'Connor, it is the insurance companies rather than the police
+who get stolen cars back."
+
+He had pulled out a postal card from a pigeon hole in his desk,
+selecting it from several apparently similar. We read:
+
+$250.00 REWARD
+
+We will pay $100.00 for car, $150.00 additional for information which
+will convict the thief. When last seen, driven by a woman, name not
+known, who is described as dark-haired, well-dressed, slight,
+apparently thirty years old. The car is a Dixon, 1912, seven-passenger,
+touring, No. 193,222, license No. 200,859, New York; dark red body,
+mohair top, brass lamps, has no wind shield; rear axle brake band
+device has extra nut on turnbuckle not painted. Car last seen near
+Prince Henry Hotel, New York City, Friday, the 10th.
+
+Communicate by telegraph or telephone, after notifying nearest police
+department, with Douglas Garwood, New York City. "The secret of it is,"
+explained Garwood, as we finished reading, "that there are innumerable
+people who keep their eyes open and like to earn money easily. Thus we
+have several hundreds of amateur and enthusiastic detectives watching
+all over the city and country for any car that looks suspicious."
+
+Kennedy thanked him for his courtesy, and we rose to go. "I shall be
+glad to keep you informed of anything that turns up," he promised.
+
+
+
+
+CHAPTER XX
+
+THE ARTIFICIAL KIDNEY
+
+
+In the laboratory, Kennedy quietly set to work. He began by tearing
+from the germ letter the piece of gelatine and first examining it with
+a pocket lens. Then, with a sterile platinum wire, he picked out
+several minute sections of the black spot on the gelatine and placed
+them in agar, blood serum, and other media on which they would be
+likely to grow.
+
+"I shall have to wait until to-morrow to examine them properly," he
+remarked. "There are colonies of something there, all right, but I must
+have them more fully developed."
+
+A hurried telephone call late in the day from Miss Sears told us that
+Mrs. Blake herself had begun to complain, and that Dr. Wilson had been
+summoned but had been unable to give an opinion on the nature of the
+malady.
+
+Kennedy quickly decided on making a visit to the doctor, who lived not
+far downtown from the laboratory.
+
+Dr. Rae Wilson proved to be a nervous little woman, inclined, I felt,
+to be dictatorial. I thought that secretly she felt a little piqued at
+our having been taken into the Blakes' confidence before herself, and
+Kennedy made every effort to smooth that aspect over tactfully.
+
+"Have you any idea what it can be?" he asked finally.
+
+She shook her head noncommittally. "I have taken blood smears," she
+answered, "but so far haven't been able to discover anything. I shall
+have to have her under observation for a day or two before I can answer
+that. Still, as Mrs. Blake is so ill, I have ordered another trained
+nurse to relieve Miss Sears of the added work, a very efficient nurse,
+a Miss Rogers."
+
+Kennedy had risen to go. "You have had no word about your car?" he
+asked casually.
+
+"None yet. I'm not worrying. It was insured."
+
+"Who is this arch criminal, Dr. Hopf?" I mused as we retraced our steps
+to the laboratory. "Is Mrs. Blake stricken now by the same trouble that
+seems to have affected Buster?"
+
+"Only my examination will show," he said. "I shall let nothing
+interfere with that now. It must be the starting point for any work
+that I may do in the case."
+
+We arrived at Kennedy's workshop of scientific crime and he immediately
+plunged into work. Looking up he caught sight of me standing helplessly
+idle.
+
+"Walter," he remarked thoughtfully adjusting a microscope, "suppose you
+run down and see Garwood. Perhaps he has something to report. And by
+the way, while you are out, make inquiries about the Blakes, young
+Baldwin, Miss Sears and this Dr. Wilson. I have heard of her before, at
+least by name. Perhaps you may find something interesting."
+
+Glad to have a chance to seem to be doing something whether it amounted
+to anything or not, I dropped in to see Garwood. So far he had nothing
+to report except the usual number of false alarms. From his office I
+went up to the Star where fortunately I found one of the reporters who
+wrote society notes.
+
+The Blakes, I found, as we already knew, to be well known and moving in
+the highest social circles. As far as known they had no particular
+enemies, other than those common to all people of great wealth. Dr.
+Wilson had a large practice, built up in recent years, and was one of
+the best known society physicians for women. Miss Sears was unknown, as
+far as I could determine. As for Duncan Baldwin, I found that he had
+become acquainted with Reginald Blake in college, that he came of no
+particular family and seemed to have no great means, although he was
+very popular in the best circles. In fact he had had, thanks to his
+friend, a rather meteoric rise in society, though it was reported that
+he was somewhat involved in debt as a result.
+
+I returned to the laboratory to find that Craig had taken out of a
+cabinet a peculiar looking arrangement. It consisted of thirty-two
+tubes, each about sixteen inches long, with S-turns, like a minute
+radiator. It was altogether not over a cubic foot in size, and enclosed
+in a glass cylinder. There were in it, perhaps, fifty feet of tubes, a
+perfectly-closed tubular system which I noticed Kennedy was keeping
+absolutely sterile in a germicidal solution of some kind.
+
+Inside the tubes and surrounding them was a saline solution which was
+kept at a uniform temperature by a special heating apparatus.
+
+Kennedy had placed the apparatus on the laboratory table and then
+gently took the little dog from his basket and laid him beside it. A
+few minutes later the poor little suffering Buster was mercifully under
+the influence of an anesthetic.
+
+Quickly Craig worked. First he attached the end of one of the tubes by
+means of a little cannula to the carotid artery of the dog. Then the
+other was attached to the jugular vein.
+
+As he released the clamp which held the artery, the little dog's
+feverishly beating heart spurted the arterial blood from the carotid
+into the tubes holding the normal salt solution and that pressure, in
+turn, pumped the salt solution which filled the tubes into the jugular
+vein, thus replacing the arterial blood that had poured into the tubes
+from the other end and maintaining the normal hydrostatic conditions in
+the body circulation. The dog was being kept alive, although perhaps a
+third of his blood was out of his body.
+
+"You see," he said at length, after we had watched the process a few
+minutes, "what I have here is in reality an artificial kidney. It is a
+system that has been devised by several doctors at Johns Hopkins.
+
+"If there is any toxin in the blood of this dog, the kidneys are
+naturally endeavoring to eliminate it. Perhaps it is being eliminated
+too slowly. In that case this arrangement which I have here will aid
+them. We call it vividiffusion and it depends for its action on the
+physical principle of osmosis, the passage of substances of a certain
+kind through a porous membrane, such as these tubes of celloidin.
+
+"Thus any substance, any poison that is dialyzable is diffused into the
+surrounding salt solution and the blood is passed back into the body,
+with no air in it, no infection, and without alteration. Clotting is
+prevented by the injection of a harmless substance derived from
+leeches, known as hirudin. I prevent the loss of anything in the blood
+which I want retained by placing in the salt solution around the tubes
+an amount of that substance equal to that held in solution by the
+blood. Of course that does not apply to the colloidal substances in the
+blood which would not pass by osmosis under any circumstances. But by
+such adjustments I can remove and study any desired substance in the
+blood, provided it is capable of diffusion. In fact this little
+apparatus has been found in practice to compare favorably with the
+kidneys themselves in removing even a lethal dose of poison."
+
+I watched in amazement. He was actually cleaning the blood of the dog
+and putting it back again, purified, into the little body. Far from
+being cruel, as perhaps it might seem, it was in reality probably the
+only method by which the animal could be saved, and at the same time it
+was giving us a clue as to some elusive, subtle substance used in the
+case.
+
+"Indeed," Kennedy went on reflectively, "this process can be kept up
+for several hours without injury to the dog, though I do not think that
+will be necessary to relieve the unwonted strain that has been put upon
+his natural organs. Finally, at the close of the operation, serious
+loss of blood is overcome by driving back the greater part of it into
+his body, closing up the artery and vein, and taking good care of the
+animal so that he will make a quick recovery."
+
+For a long time I watched the fascinating process of seeing the life
+blood coursing through the porous tubes in the salt solution, while
+Kennedy gave his undivided attention to the success of the delicate
+experiment. It was late when I left him, still at work over Buster, and
+went up to our apartment to turn in, convinced that nothing more would
+happen that night.
+
+The next morning, with characteristic energy, Craig was at work early,
+examining the cultures he had made from the black spots on the gelatine.
+
+By the look of perplexity on his face, I knew that he had discovered
+something that instead of clearing the mystery up, further deepened it.
+
+"What do you find?" I asked anxiously.
+
+"Walter," he exclaimed, laying aside the last of the slides which he
+had been staining and looking at intently through the microscope, "that
+stuff on the gelatine is entirely harmless. There was nothing in it
+except common mold."
+
+For the moment I did not comprehend. "Mold?" I repeated.
+
+"Yes," he replied, "just common, ordinary mold such as grows on the top
+of a jar of fruit or preserves when it is exposed to the air."
+
+I stifled an exclamation of incredulity. It seemed impossible that the
+deadly germ note should be harmless, in view of the events that had
+followed its receipt.
+
+Just then the laboratory door was flung open and Reginald Blake, pale
+and excited, entered. He had every mark of having been up all night.
+
+"What's the matter?" asked Craig.
+
+"It's about my mother," he blurted out. "She seems to be getting worse
+all the time. Miss Sears is alarmed, and Betty is almost ill herself
+with worry. Dr. Wilson doesn't seem to know what it is that affects
+her, and neither does the new nurse. Can you DO something?"
+
+There was a tone of appeal in his voice that was not like the
+self-sufficient Reginald of the day before.
+
+"Does there seem to be any immediate danger?" asked Kennedy.
+
+"Perhaps not--I can't say," he urged. "But she is gradually getting
+worse instead of better."
+
+Kennedy thought a moment. "Has anything else happened?" he asked slowly.
+
+"N-no. That's enough, isn't it?"
+
+"Indeed it is," replied Craig, trying to be reassuring. Then,
+recollecting Betty, he added, "Reginald, go back and tell your sister
+for me that she must positively make the greatest effort of her life to
+control herself. Tell her that her mother needs her--needs her well and
+brave. I shall be up at the house immediately. Do the best you can. I
+depend on you."
+
+Kennedy's words seemed to have a bracing effect on Reginald and a few
+moments later he left, much calmer.
+
+"I hope I have given him something to do which will keep him from
+mussing things up again," remarked Kennedy, mindful of Reginald's
+former excursion into detective work.
+
+Meanwhile Craig plunged furiously into his study of the substances he
+had isolated from the saline solution in which he had "washed" the
+blood of the little Pekinese.
+
+"There's no use doing anything in the dark," he explained. "Until we
+know what it is we are fighting we can't very well fight."
+
+For the moment I was overwhelmed by the impending tragedy that seemed
+to be hanging over Mrs. Blake. The more I thought of it, the more
+inexplicable became the discovery of the mold.
+
+"That is all very well about the mold on the gelatine strip in the
+letter," I insisted at length. "But, Craig, there must be something
+wrong somewhere. Mere molds could not have made Buster so ill, and now
+the infection, or whatever it is, has spread to Mrs. Blake herself.
+What have you found out by studying Buster?"
+
+He looked up from his close scrutiny of the material in one of the test
+tubes which contained something he had recovered from the saline
+solution of the diffusion apparatus.
+
+I could read on his face that whatever it was, it was serious. "What is
+it?" I repeated almost breathlessly.
+
+"I suppose I might coin a word to describe it," he answered slowly,
+measuring his phrases. "Perhaps it might be called
+hyper-amino-acidemia."
+
+I puckered my eyes at the mouth-filling term Kennedy smiled. "It would
+mean," he explained, "a great quantity of the amino-acids,
+non-coagulable, nitrogenous compounds in the blood. You know the
+indols, the phenols, and the amins are produced both by putrefactive
+bacteria and by the process of metabolism, the burning up of the
+tissues in the process of utilizing the energy that means life. But
+under normal circumstances, the amins are not present in the blood in
+any such quantities as I have discovered by this new method of
+diffusion."
+
+He paused a moment, as if in deference to my inability to follow him on
+such an abstruse topic, then resumed, "As far as I am able to
+determine, this poison or toxin is an amin similar to that secreted by
+certain cephalopods found in the neighborhood of Naples. It is an
+aromatic amin. Smell it."
+
+I bent over and inhaled the peculiar odor.
+
+"Those creatures," he continued, "catch their prey by this highly
+active poison secreted by the so-called salivary glands. Even a little
+bit will kill a crab easily."
+
+I was following him now with intense interest, thinking of the
+astuteness of a mind capable of thinking of such a poison.
+
+"Indeed, it is surprising," he resumed thoughtfully, "how many an
+innocent substance can be changed by bacteria into a virulent poison.
+In fact our poisons and our drugs are in many instances the close
+relations of harmless compounds that represent the intermediate steps
+in the daily process of metabolism."
+
+"Then," I put in, "the toxin was produced by germs, after all?"
+
+"I did not say that," he corrected. "It might have been. But I find no
+germs in the blood of Buster. Nor did Dr. Wilson find any in the blood
+smears which she took from Mrs. Blake."
+
+He seemed to have thrown the whole thing back again into the limbo of
+the unexplainable, and I felt nonplussed.
+
+"The writer of that letter," he went on, waving the piece of sterile
+platinum wire with which he had been transferring drops of liquid in
+his search for germs, "was a much more skillful bacteriologist than I
+thought, evidently. No, the trouble does not seem to be from germs
+breathed in, or from germs at all--it is from some kind of germ-free
+toxin that has been injected or otherwise introduced."
+
+Vaguely now I began to appreciate the terrible significance of what he
+had discovered.
+
+"But the letter?" I persisted mechanically.
+
+"The writer of that was quite as shrewd a psychologist as
+bacteriologist," pursued Craig impressively. "He calculated the moral
+effect of the letter, then of Buster's illness, and finally of reaching
+Mrs. Blake herself."
+
+"You think Dr. Rae Wilson knows nothing of it yet?" I queried.
+
+Kennedy appeared to consider his answer carefully. Then he said slowly:
+"Almost any doctor with a microscope and the faintest trace of a
+scientific education could recognize disease germs either naturally or
+feloniously implanted. But when it comes to the detection of
+concentrated, filtered, germ-free toxins, almost any scientist might be
+baffled. Walter," he concluded, "this is not mere blackmail, although
+perhaps the visit of that woman to the Prince Henry--a desperate thing
+in itself, although she did get away by her quick thinking--perhaps
+that shows that these people are ready to stop at nothing. No, it goes
+deeper than blackmail."
+
+I stood aghast at the discovery of this new method of scientific
+murder. The astute criminal, whoever he might be, had planned to leave
+not even the slender clue that might be afforded by disease germs. He
+was operating, not with disease itself, but with something showing the
+ultimate effects, perhaps, of disease with none of the preliminary
+symptoms, baffling even to the best of physicians.
+
+I scarcely knew what to say. Before I realized it, however, Craig was
+at last ready for the promised visit to Mrs. Blake. We went together,
+carrying Buster, in his basket, not recovered, to be sure, but a very
+different little animal from the dying creature that had been sent to
+us at the laboratory.
+
+
+
+
+CHAPTER XXI
+
+THE POISON BRACELET
+
+
+We reached the Blake mansion and were promptly admitted. Miss Betty,
+bearing up bravely under Reginald's reassurances, greeted us before we
+were fairly inside the door, though she and her brother were not able
+to conceal the fact that their mother was no better. Miss Sears was
+out, for an airing, and the new nurse, Miss Rogers, was in charge of
+the patient.
+
+"How do you feel, this morning?" inquired Kennedy as we entered the
+sun-parlor, where Mrs. Blake had first received us.
+
+A single glance was enough to satisfy me of the seriousness of her
+condition. She seemed to be in almost a stupor from which she roused
+herself only with difficulty. It was as if some overpowering toxin were
+gradually undermining her already weakened constitution.
+
+She nodded recognition, but nothing further.
+
+Kennedy had set the dog basket down near her wheel-chair and she caught
+sight of it.
+
+"Buster?" she murmured, raising her eyes. "Is--he--all right?"
+
+For answer, Craig simply raised the lid of the basket. Buster already
+seemed to have recognized the voice of his mistress, and, with an
+almost human instinct, to realize that though he himself was still weak
+and ill, she needed encouragement.
+
+As Mrs. Blake stretched out her slender hand, drawn with pain, to his
+silky head, he gave a little yelp of delight and his little red tongue
+eagerly caressed her hand.
+
+It was as though the two understood each other. Although Mrs. Blake, as
+yet, had no more idea what had happened to her pet, she seemed to feel
+by some subtle means of thought transference that the intelligent
+little animal was conveying to her a message of hope. The caress, the
+sharp, joyous yelp, and the happy wagging of the bushy tail seemed to
+brighten her up, at least for the moment, almost as if she had received
+a new impetus.
+
+"Buster!" she exclaimed, overjoyed to get her pet back again in so much
+improved condition.
+
+"I wouldn't exert myself too much, Mrs. Blake," cautioned Kennedy.
+
+"Were--were there any germs in the letter?" she asked, as Reginald and
+Betty stood on the other side of the chair, much encouraged,
+apparently, at this show of throwing off the lethargy that had seized
+her.
+
+"Yes, but about as harmless as those would be on a piece of cheese,"
+Kennedy hastened. "But I--I feel so weak, so played out--and my head--"
+
+Her voice trailed off, a too evident reminder that her improvement had
+been only momentary and prompted by the excitement of our arrival.
+
+Betty bent down solicitously and made her more comfortable as only one
+woman can make another. Kennedy, meanwhile, had been talking to Miss
+Rogers, and I could see that he was secretly taking her measure.
+
+"Has Dr. Wilson been here this morning?" I heard him ask.
+
+"Not yet," she replied. "But we expect her soon."
+
+"Professor Kennedy?" announced a servant.
+
+"Yes?" answered Craig.
+
+"There is someone on the telephone who wants to speak to you. He said
+he had called the laboratory first and that they told him to call you
+here."
+
+Kennedy hurried after the servant, while Betty and Reginald joined me,
+waiting, for we seemed to feel that something was about to happen.
+
+"One of the unofficial detectives has unearthed a clue," he whispered
+to me a few moments later when he returned. "It was Garwood." Then to
+the others he added, "A car, repainted, and with the number changed,
+but otherwise answering the description of Dr. Wilson's has been traced
+to the West Side. It is somewhere in the neighborhood of a saloon and
+garage where drivers of taxicabs hang out. Reginald, I wish you would
+come along with us."
+
+To Betty's unspoken question Craig hastened to add, "I don't think
+there is any immediate danger. If there is any change--let me know. I
+shall call up soon. And meanwhile," he lowered his voice to impress the
+instruction on her, "don't leave your mother for a moment--not for a
+moment," he emphasized.
+
+Reginald was ready and together we three set off to meet Garwood at a
+subway station near the point where the car had been reported. We had
+scarcely closed the front door, when we ran into Duncan Baldwin, coming
+down the street, evidently bent on inquiring how Mrs. Blake and Betty
+were.
+
+"Much better," reassured Kennedy. "Come on, Baldwin. We can't have too
+many on whom we can rely on an expedition like this."
+
+"Like what?" he asked, evidently not comprehending.
+
+"There's a clue, they think, to that car of Dr. Wilson's," hastily
+explained Reginald, linking his arm into that of his friend and falling
+in behind us, as Craig hurried ahead.
+
+It did not take long to reach the subway, and as we waited for the
+train, Craig remarked: "This is a pretty good example of how the
+automobile is becoming one of the most dangerous of criminal weapons.
+All one has to do nowadays, apparently, after committing a crime, is to
+jump into a waiting car and breeze away, safe."
+
+We met Garwood and under his guidance picked our way westward from the
+better known streets in the heart of the city, to a section that was
+anything but prepossessing.
+
+The place which Garwood sought was a typical Raines Law hotel on a
+corner, with a saloon on the first floor, and apparently the requisite
+number of rooms above to give it a legal license.
+
+We had separated a little so that we would not attract undue attention.
+Kennedy and I entered the swinging doors boldly, while the others
+continued across to the other corner to wait with Garwood and take in
+the situation. It was a strange expedition and Reginald was fidgeting
+while Duncan seemed nervous.
+
+Among the group of chauffeurs lounging at the bar and in the back room
+anyone who had ever had any dealings with the gangs of New York might
+have recognized the faces of men whose pictures were in the rogues'
+gallery and who were members of those various aristocratic
+organizations of the underworld.
+
+Kennedy glanced about at the motley crowd. "This is a place where you
+need only to be introduced properly," he whispered to me, "to have any
+kind of crime committed for you."
+
+As we stood there, observing, without appearing to do so, through an
+open window on the side street I could tell from the sounds that there
+was a garage in the rear of the hotel.
+
+We were startled to hear a sudden uproar from the street.
+
+Garwood, impatient at our delay, had walked down past the garage to
+reconnoiter. A car was being backed out hurriedly, and as it turned and
+swung around the corner, his trained eye had recognized it.
+
+Instantly he had reasoned that it was an attempt to make a getaway, and
+had raised an alarm.
+
+Those nearest the door piled out, keen for any excitement. We, too,
+dashed out on the street. There we saw passing an automobile, swaying
+and lurching at the terrific speed with which its driver, urged it up
+the avenue. As he flashed by he looked like an Italian to me, perhaps a
+gunman.
+
+Garwood had impressed a passing trolley car into service and was
+pursuing the automobile in it, as it swayed on its tracks as crazily as
+the motor did on the roadway, running with all the power the motorman
+could apply.
+
+A mounted policeman galloped past us, blazing away at the tires. The
+avenue was stirred, as seldom even in its strenuous life, with reports
+of shots, honking of horns, the clang of trolley bells and the shouts
+of men.
+
+The pursuers were losing when there came a rattle and roar from the
+rear wheels which told that the tires were punctured and the heavy car
+was riding on its rims. A huge brewery wagon crossing a side street
+paused to see the fun, effectually blocking the road.
+
+The car jolted to a stop. The chauffeur leaped out and a moment later
+dived down into a cellar. In that congested district, pursuit was
+useless.
+
+"Only an accomplice," commented Kennedy. "Perhaps we can get him some
+other way if we can catch the man--or woman--higher up."
+
+Down the street now we could see Garwood surrounded by a curious crowd
+but in possession of the car. I looked about for Duncan and Reginald.
+They had apparently been swallowed up in the crowds of idlers which
+seemed to be pouring out of nowhere, collecting to gape at the
+excitement, after the manner of a New York crowd.
+
+As I ran my eye over them, I caught sight of Reginald near the corner
+where we had left him in an incipient fight with someone who had a
+fancied grievance. A moment later we had rescued him.
+
+"Where's Duncan?" he panted. "Did anything happen to him? Garwood told
+us to stay here--but we got separated."
+
+Policemen had appeared on the heels of the crowd and now, except for a
+knot following Garwood, things seemed to be calming down.
+
+The excitement over, and the people thinning out, Kennedy still could
+not find any trace of Duncan. Finally he glanced in again through the
+swinging doors. There was Duncan, evidently quite upset by what had
+occurred, fortifying himself at the bar.
+
+Suddenly from above came a heavy thud, as if someone had fallen on the
+floor above us, followed by a suppressed shuffling of feet and a cry of
+help.
+
+Kennedy sprang toward a side door which led out into the hall to the
+hotel room above. It was locked. Before any of the others he ran out on
+the street and into the hall that way, taking the stairs two at a time,
+past a little cubby-hole of an "office" and down the upper hall to a
+door from which came the cry.
+
+It was a peculiar room into which we burst, half bedroom, half
+workshop, or rather laboratory, for on a deal table by a window stood a
+rack of test-tubes, several beakers, and other paraphernalia.
+
+A chambermaid was shrieking over a woman who was lying lethargic on the
+floor.
+
+I looked more closely.
+
+It was Dora Sears.
+
+For the moment I could not imagine what had happened. Had the events of
+the past few days worked on her mind and driven her into temporary
+insanity? Or had the blackmailing gang of automobile thieves, failing
+in extorting money by their original plan, seized her?
+
+Kennedy bent over and tried to lift her up. As he did so, the gold
+bracelet, unclasped, clattered to the floor.
+
+He picked it up and for a moment looked at it. It was hollow, but in
+that part of it where it unclasped could be seen a minute hypodermic
+needle and traces of a liquid.
+
+"A poison bracelet," he muttered to himself, "one in which enough of a
+virulent poison could be hidden so that in an emergency death could
+cheat the law."
+
+"But this Dr. Hopf," exclaimed Reginald, who stood behind us looking
+from the insensible girl to the bracelet and slowly comprehending what
+it all meant, "she alone knows where and who he is!"
+
+We looked at Kennedy. What was to be done? Was the criminal higher up
+to escape because one of his tools had been cornered and had taken the
+easiest way to get out?
+
+Kennedy had taken down the receiver of the wall telephone in the room.
+A moment later he was calling insistently for his laboratory. One of
+the students in another part of the building answered. Quickly he
+described the apparatus for vividiffusion and how to handle it without
+rupturing any of the delicate tubes.
+
+"The large one," he ordered, "with one hundred and ninety-two tubes.
+And hurry."
+
+Before the student appeared, came an ambulance which some one in the
+excitement had summoned. Kennedy quickly commandeered both the young
+doctor and what surgical material he had with him.
+
+Briefly he explained what he proposed to do and before the student
+arrived with the apparatus, they had placed the nurse in such a
+position that they were ready for the operation.
+
+The next room which was unoccupied had been thrown open to us and there
+I waited with Reginald and Duncan, endeavoring to explain to them the
+mysteries of the new process of washing the blood.
+
+The minutes lengthened into hours, as the blood of the poisoned girl
+coursed through its artificial channel, literally being washed of the
+toxin from the poisoned bracelet.
+
+Would it succeed? It had saved the life of Buster. But would it bring
+back the unfortunate before us, long enough even for her to yield her
+secret and enable us to catch the real criminal. What if she died?
+
+As Kennedy worked, the young men with me became more and more
+fascinated, watching him. The vividiffusion apparatus was now in full
+operation.
+
+In the intervals when he left the apparatus in charge of the young
+ambulance surgeon Kennedy was looking over the room. In a trunk which
+was open he found several bundles of papers. As he ran his eye over
+them quickly, he selected some and stuffed them into his pocket, then
+went back to watch the working of the apparatus.
+
+Reginald, who had been growing more and more nervous, at last asked if
+he might call up Betty to find out how his mother was.
+
+He came back from the telephone, his face wrinkled.
+
+"Poor mother," he remarked anxiously, "do you think she will pull
+through, Professor? Betty says that Dr. Wilson has given her no idea
+yet about the nature of the trouble."
+
+Kennedy thought a moment. "Of course," he said, "your mother has had no
+such relative amount of the poison as Buster has had. I think that
+undoubtedly she will recover by purely natural means. I hope so. But if
+not, here is the apparatus," and he patted the vividiffusion tubes in
+their glass case, "that will save her, too."
+
+As well as I could I explained to Reginald the nature of the toxin that
+Kennedy had discovered. Duncan listened, putting in a question now and
+then. But it was evident that his thoughts were on something else, and
+now and then Reginald, breaking into his old humor, rallied him about
+thinking of Betty.
+
+A low exclamation from both Kennedy and the surgeon attracted us.
+
+Dora Sears had moved.
+
+The operation of the apparatus was stopped, the artery and vein had
+been joined up, and she was slowly coming out from under the effects of
+the anesthetic.
+
+As we gathered about her, at a little distance, we heard her cry in her
+delirium, "I--I would have--done--anything--for him."
+
+We strained our ears. Was she talking of the blackmailer, Dr. Hopf?
+
+"Who?" asked Craig, bending over close to her ear.
+
+"I--I would--have done anything," she repeated as if someone had
+contradicted her. She went on, dreamily, ramblingly, "He--is--is--my
+brother. I--"
+
+She stopped through weakness.
+
+"Where is Dr. Hopf?" asked Kennedy, trying to recall her fleeting
+attention.
+
+"Dr. Hopf? Dr. Hopf?" she repeated, then smiling to herself as people
+will when they are leaving the borderline of anesthesia, she repeated
+the name, "Hopf?"
+
+"Yes," persisted Kennedy.
+
+"There is no Dr. Hopf," she added. "Tell me--did--did they--"
+
+"No Dr. Hopf?" Kennedy insisted.
+
+She had lapsed again into half insensibility.
+
+He rose and faced us, speaking rapidly.
+
+"New York seems to have a mysterious and uncanny attraction for odds
+and ends of humanity, among them the great army of adventuresses. In
+fact there often seems to be something decidedly adventurous about the
+nursing profession. This is a girl of unusual education in medicine.
+Evidently she has traveled--her letters show it. Many of them show that
+she has been in Italy. Perhaps it was there that she heard of the drug
+that has been used in this case. It was she who injected the germ-free
+toxin, first into the dog, then into Mrs. Blake, she who wrote the
+blackmail letter which was to have explained the death."
+
+He paused. Evidently she had heard dimly, was straining every effort to
+hear. In her effort she caught sight of our faces.
+
+Suddenly, as if she had seen an apparition, she raised herself with
+almost superhuman strength.
+
+"Duncan!" she cried. "Duncan! Why--didn't you--get away--while there
+was time--after you warned me?"
+
+Kennedy had wheeled about and was facing us. He was holding in his hand
+some of the letters he had taken from the trunk. Among others was a
+folded piece of parchment that looked like a diploma. He unfolded it
+and we bent over to read.
+
+It was a diploma from the Central Western College of Nursing. As I read
+the name written in, it was with a shock. It was not Dora Sears, but
+Dora Baldwin.
+
+"A very clever plot," he ground out, taking a step nearer us. "With the
+aid of your sister and a disreputable gang of chauffeurs you planned to
+hasten the death of Mrs. Blake, to hasten the inheritance of the Blake
+fortune by your future wife. I think your creditors will have less
+chance of collecting now than ever, Duncan Baldwin."
+
+
+
+
+CHAPTER XXII
+
+THE DEVIL WORSHIPERS
+
+
+Tragic though the end of the young nurse, Dora Baldwin, had been, the
+scheme of her brother, in which she had become fatally involved, was by
+no means as diabolical as that in the case that confronted us a short
+time after that.
+
+I recall this case particularly not only because it was so weird but
+also because of the unique manner in which it began.
+
+"I am damned--Professor Kennedy--damned!"
+
+The words rang out as the cry of a lost soul. A terrible look of
+inexpressible anguish and fear was written on the face of Craig's
+visitor, as she uttered them and sank back, trembling, in the easy
+chair, mentally and physically convulsed.
+
+As nearly as I had been able to follow, Mrs. Veda Blair's story had
+dealt mostly with a Professor and Madame Rapport and something she
+called the "Red Lodge" of the "Temple of the Occult."
+
+She was not exactly a young woman, although she was a very attractive
+one. She was of an age that is, perhaps, even more interesting than
+youth.
+
+Veda Blair, I knew, had been, before her recent marriage to Seward
+Blair, a Treacy, of an old, though somewhat unfortunate, family. Both
+the Blairs and the Treacys had been intimate and old Seward Blair, when
+he died about a year before, had left his fortune to his son on the
+condition that he marry Veda Treacy.
+
+"Sometimes," faltered Mrs. Blair, "it is as though I had two souls. One
+of them is dispossessed of its body and the use of its organs and is
+frantic at the sight of the other that has crept in."
+
+She ended her rambling story, sobbing the terrible words, "Oh--I have
+committed the unpardonable sin--I am anathema--I am damned--damned!"
+
+She said nothing of what terrible thing she had done and Kennedy, for
+the present, did not try to lead the conversation. But of all the
+stories that I have heard poured forth in the confessional of the
+detective's office, hers, I think, was the wildest.
+
+Was she insane? At least I felt that she was sincere. Still, I wondered
+what sort of hallucination Craig had to deal with, as Veda Blair
+repeated the incoherent tale of her spiritual vagaries.
+
+Almost, I had begun to fancy that this was a case for a doctor, not for
+a detective, when suddenly she asked a most peculiar question.
+
+"Can people affect you for good or evil, merely by thinking about you?"
+she queried. Then a shudder passed over her. "They may be thinking
+about me now!" she murmured in terror.
+
+Her fear was so real and her physical distress so evident that Kennedy,
+who had been listening silently for the most part, rose and hastened to
+reassure her.
+
+"Not unless you make your own fears affect yourself and so play into
+their hands," he said earnestly.
+
+Veda looked at him a moment, then shook her head mournfully. "I have
+seen Dr. Vaughn," she said slowly.
+
+Dr. Gilbert Vaughn, I recollected, was a well-known alienist in the
+city.
+
+"He tried to tell me the same thing," she resumed doubtfully.
+"But--oh--I know what I know! I have felt the death thought--and he
+knows it!"
+
+"What do you mean?" inquired Kennedy, leaning forward keenly.
+
+"The death thought," she repeated, "a malicious psychic attack. Some
+one is driving me to death by it. I thought I could fight it off. I
+went away to escape it. Now I have come back--and I have not escaped.
+There is always that disturbing influence--always--directed against me.
+I know it will--kill me!"
+
+I listened, startled. The death thought! What did it mean? What
+terrible power was it? Was it hypnotism? What was this fearsome, cruel
+belief, this modern witchcraft that could unnerve a rich and educated
+woman? Surely, after all, I felt that this was not a case for a doctor
+alone; it called for a detective.
+
+"You see," she went on, heroically trying to control herself, "I have
+always been interested in the mysterious, the strange, the occult. In
+fact my father and my husband's father met through their common
+interest. So, you see, I come naturally by it.
+
+"Not long ago I heard of Professor and Madame Rapport and their new
+Temple of the Occult. I went to it, and later Seward became interested,
+too. We have been taken into a sort of inner circle," she continued
+fearfully, as though there were some evil power in the very words
+themselves, "the Red Lodge."
+
+"You have told Dr. Vaughn?" shot out Kennedy suddenly, his eyes fixed
+on her face to see what it would betray.
+
+Veda leaned forward, as if to tell a secret, then whispered in a low
+voice, "He knows. Like us--he--he is a--Devil Worshiper!"
+
+"What?" exclaimed Kennedy in wide-eyed astonishment.
+
+"A Devil Worshiper," she repeated. "You haven't heard of the Red Lodge?"
+
+Kennedy nodded negatively. "Could you get us--initiated?" he hazarded.
+
+"P--perhaps," she hesitated, in a half-frightened tone. "I--I'll try to
+get you in to-night."
+
+She had risen, half dazed, as if her own temerity overwhelmed her.
+
+"You--poor girl," blurted out Kennedy, his sympathies getting the upper
+hand for the moment as he took the hand she extended mutely. "Trust me.
+I will do all in my power, all in the power of modern science to help
+you fight off this--influence."
+
+There must have been something magnetic, hypnotic in his eye.
+
+"I will stop here for you," she murmured, as she almost fled from the
+room.
+
+Personally, I cannot say that I liked the idea of spying. It is not
+usually clean and wholesome. But I realized that occasionally it was
+necessary.
+
+"We are in for it now," remarked Kennedy half humorously, half
+seriously, "to see the Devil in the twentieth century."
+
+"And I," I added, "I am, I suppose, to be the reporter to Satan."
+
+We said nothing more about it, but I thought much about it, and the
+more I thought, the more incomprehensible the thing seemed. I had heard
+of Devil Worship, but had always associated it with far-off Indian and
+other heathen lands--in fact never among Caucasians in modern times,
+except possibly in Paris. Was there such a cult here in my own city? I
+felt skeptical.
+
+That night, however, promptly at the appointed time, a cab called for
+us, and in it was Veda Blair, nervous but determined.
+
+"Seward has gone ahead," she explained. "I told him that a friend had
+introduced you, that you had studied the occult abroad. I trust you to
+carry it out."
+
+Kennedy reassured her.
+
+The curtains were drawn and we could see nothing outside, though we
+must have been driven several miles, far out into the suburbs.
+
+At last the cab stopped. As we left it we could see nothing of the
+building, for the cab had entered a closed courtyard.
+
+"Who enters the Red Lodge?" challenged a sepulchral voice at the
+porte-cochere. "Give the password!"
+
+"The Serpent's Tooth," Veda answered.
+
+"Who are these?" asked the voice.
+
+"Neophytes," she replied, and a whispered parley followed.
+
+"Then enter!" announced the voice at length.
+
+It was a large room into which we were first ushered, to be inducted
+into the rites of Satan.
+
+There seemed to be both men and women, perhaps half a dozen votaries.
+Seward Blair was already present. As I met him, I did not like the look
+in his eye; it was too stary. Dr. Vaughn was there, too, talking in a
+low tone to Madame Rapport. He shot a quick look at us. His were not
+eyes but gimlets that tried to bore into your very soul. Chatting with
+Seward Blair was a Mrs. Langhorne, a very beautiful woman. To-night she
+seemed to be unnaturally excited.
+
+All seemed to be on most intimate terms, and, as we waited a few
+minutes, I could not help recalling a sentence from Huysmans: "The
+worship of the Devil is no more insane than the worship of God. The
+worshipers of Satan are mystics--mystics of an unclean sort, it is
+true, but mystics none the less."
+
+I did not agree with it, and did not repeat it, of course, but a moment
+later I overheard Dr. Vaughn saying to Kennedy: "Hoffman brought the
+Devil into modern life. Poe forgoes the aid of demons and works
+patiently and precisely by the scientific method. But the result is the
+same."
+
+"Yes," agreed Kennedy for the sake of appearances, "in a sense, I
+suppose, we are all devil worshipers in modern society--always have
+been. It is fear that rules and we fear the bad--not the good."
+
+As we waited, I felt, more and more, the sense of the mysterious, the
+secret, the unknown which have always exercised a powerful attraction
+on the human mind. Even the aeroplane and the submarine, the X-ray and
+wireless have not banished the occult.
+
+In it, I felt, there was fascination for the frivolous and deep appeal
+to the intellectual and spiritual. The Temple of the Occult had
+evidently been designed to appeal to both types. I wondered how, like
+Lucifer, it had fallen. The prime requisite, I could guess already,
+however, was--money. Was it in its worship of the root of all evil that
+it had fallen?
+
+We passed soon into another room, hung entirely in red, with weird,
+cabalistic signs all about, on the walls. It was uncanny, creepy.
+
+A huge reproduction in plaster of one of the most sardonic of Notre
+Dame's gargoyles seemed to preside over everything--a terrible figure
+in such an atmosphere.
+
+As we entered, we were struck by the blinding glare of the light, in
+contrast with the darkened room in which we had passed our brief
+novitiate, if it might be called such.
+
+Suddenly the lights were extinguished.
+
+The great gargoyle shone with an infernal light of its own!
+
+"Phosphorescent paint," whispered Kennedy to me.
+
+Still, it did not detract from the weird effect to know what caused it.
+
+There was a startling noise in the general hush.
+
+"Sata!" cried one of the devotees.
+
+A door opened and there appeared the veritable priest of the
+Devil--pale of face, nose sharp, mouth bitter, eyes glassy.
+
+"That is Rapport," Vaughn whispered to me.
+
+The worshipers crowded forward.
+
+Without a word, he raised his long, lean forefinger and began to single
+them out impressively. As he did so, each spoke, as if imploring aid.
+
+He came to Mrs. Langhorne.
+
+"I have tried the charm," she cried earnestly, "and the one whom I love
+still hates me, while the one I hate loves me!"
+
+"Concentrate!" replied the priest, "concentrate! Think always 'I love
+him. He must love me. I want him to love me. I love him. He must love
+me.' Over and over again you must think it. Then the other side, 'I
+hate him. He must leave me. I want him to leave me. I hate him--hate
+him.'"
+
+Around the circle he went.
+
+At last his lean finger was outstretched at Veda. It seemed as if some
+imp of the perverse were compelling her unwilling tongue to unlock its
+secrets.
+
+"Sometimes," she cried in a low, tremulous voice, "something seems to
+seize me, as if by the hand and urge me onward. I cannot flee from it."
+
+"Defend yourself!" answered the priest subtly. "When you know that some
+one is trying to kill you mentally, defend yourself! Work against it by
+every means in your power. Discourage! Intimidate! Destroy!"
+
+I marveled at these cryptic utterances. They shadowed a modern Black
+Art, of which I had had no conception--a recrudescence in other
+language of the age-old dualism of good and evil. It was a sort of
+mental malpractice.
+
+"Over and over again," he went on speaking to her, "the same thought is
+to be repeated against an enemy. 'You know you are going to die! You
+know you are going to die!' Do it an hour, two hours, at a time. Others
+can help you, all thinking in unison the same thought."
+
+What was this, I asked myself breathlessly--a new transcendental
+toxicology?
+
+Slowly, a strange mephitic vapor seemed to exhale into the room--or was
+it my heightened imagination?
+
+
+
+
+CHAPTER XXIII
+
+THE PSYCHIC CURSE
+
+
+There came a sudden noise--nameless--striking terror, low, rattling. I
+stood rooted to the spot. What was it that held me? Was it an atavistic
+joy in the horrible or was it merely a blasphemous curiosity?
+
+I scarcely dared to look.
+
+At last I raised my eyes. There was a live snake, upraised, his fangs
+striking out viciously--a rattler!
+
+I would have drawn back and fled, but Craig caught my arm.
+
+"Caged," he whispered monosyllabically.
+
+I shuddered. This, at least, was no drawing-room diablerie.
+
+"It is Ophis," intoned Rapport, "the Serpent--the one active form in
+Nature that cannot be ungraceful!"
+
+The appearance of the basilisk seemed to heighten the tension.
+
+At last it broke loose and then followed the most terrible blasphemies.
+The disciples, now all frenzied, surrounded closer the priest, the
+gargoyle and the serpent.
+
+They worshiped with howls and obscenities. Mad laughter mingled with
+pale fear and wild scorn in turns were written on the hectic faces
+about me.
+
+They had risen--it became a dance, a reel.
+
+The votaries seemed to spin about on their axes, as it were, uttering a
+low, moaning chant as they whirled. It was a mania, the spirit of
+demonism. Something unseen seemed to urge them on.
+
+Disgusted and stifled at the surcharged atmosphere, I would have tried
+to leave, but I seemed frozen to the spot. I could think of nothing
+except Poe's Masque of the Red Death.
+
+Above all the rest whirled Seward Blair himself. The laugh of the
+fiend, for the moment, was in his mouth. An instant he stood--the
+oracle of the Demon--devil-possessed. Around whirled the frantic
+devotees, howling.
+
+Shrilly he cried, "The Devil is in me!"
+
+Forward staggered the devil dancer--tall, haggard, with deep sunken
+eyes and matted hair, face now smeared with dirt and blood-red with the
+reflection of the strange, unearthly phosphorescence.
+
+He reeled slowly through the crowd, crooning a quatrain, in a low,
+monotonous voice, his eyelids drooping and his head forward on his
+breast:
+
+ If the Red Slayer think he slays,
+ Or the slain think he is slain,
+ They know not well the subtle ways
+ I keep and pass and turn again!
+
+Entranced the whirling crowd paused and watched. One of their number
+had received the "power."
+
+He was swaying slowly to and fro.
+
+"Look!" whispered Kennedy.
+
+His fingers twitched, his head wagged uncannily. Perspiration seemed to
+ooze from every pore. His breast heaved.
+
+He gave a sudden yell--ear-piercing. Then followed a screech of hellish
+laughter.
+
+The dance had ended, the dancers spellbound at the sight.
+
+He was whirling slowly, eyes protruding now, mouth foaming, chest
+rising and falling like a bellows, muscles quivering.
+
+Cries, vows, imprecations, prayers, all blended in an infernal hubbub.
+
+With a burst of ghastly, guttural laughter, he shrieked, "I AM the
+Devil!"
+
+His arms waved--cutting, sawing, hacking the air.
+
+The votaries, trembling, scarcely moved, breathed, as he danced.
+
+Suddenly he gave a great leap into the air--then fell, motionless. They
+crowded around him. The fiendish look was gone--the demoniac laughter
+stilled.
+
+It was over.
+
+The tension of the orgy had been too much for us. We parted, with
+scarcely a word, and yet I could feel that among the rest there was a
+sort of unholy companionship.
+
+Silently, Kennedy and I drove away in the darkened cab, this time with
+Seward and Veda Blair and Mrs. Langhorne.
+
+For several minutes not a word was said. I was, however, much occupied
+in watching the two women. It was not because of anything they said or
+did. That was not necessary. But I felt that there was a feud,
+something that set them against each other.
+
+"How would Rapport use the death thought, I wonder?" asked Craig
+speculatively, breaking the silence.
+
+Blair answered quickly. "Suppose some one tried to break away, to
+renounce the Lodge, expose its secrets. They would treat him so as to
+make him harmless--perhaps insane, confused, afraid to talk, paralyzed,
+or even to commit suicide or be killed in an accident. They would put
+the death thought on him!"
+
+Even in the prosaic jolting of the cab, away from the terrible
+mysteries of the Red Lodge, one could feel the spell.
+
+The cab stopped. Seward was on his feet in a moment and handing Mrs.
+Langhorne out at her home. For a moment they paused on the steps for an
+exchange of words.
+
+In that moment I caught flitting over the face of Veda a look of
+hatred, more intense, more real, more awful than any that had been
+induced under the mysteries of the rites at the Lodge.
+
+It was gone in an instant, and as Seward rejoined us I felt that, with
+Mrs. Langhorne gone, there was less restraint. I wondered whether it
+was she who had inspired the fear in Veda.
+
+Although it was more comfortable, the rest of our journey was made in
+silence and the Blairs dropped us at our apartment with many
+expressions of cordiality as we left them to proceed to their own.
+
+"Of one thing I'm sure," I remarked, entering the room where only a few
+short hours before Mrs. Blair had related her strange tale. "Whatever
+the cause of it, the devil dancers don't sham."
+
+Kennedy did not reply. He was apparently wrapped up in the
+consideration of the remarkable events of the evening.
+
+As for myself, it was a state of affairs which, the day before, I
+should have pronounced utterly beyond the wildest bounds of the
+imagination of the most colorful writer. Yet here it was; I had seen it.
+
+I glanced up to find Kennedy standing by the light examining something
+he had apparently picked up at the Red Lodge. I bent over to look at
+it, too. It was a little glass tube.
+
+"An ampoule, I believe the technical name of such a container is," he
+remarked, holding it closer to the light.
+
+In it were the remains of a dried yellow substance, broken up minutely,
+resembling crystals.
+
+"Who dropped it?" I asked.
+
+"Vaughn, I think," he replied. "At least, I saw him near Blair,
+stooping over him, at the end, and I imagine this is what I saw
+gleaming for an instant in the light."
+
+Kennedy said nothing more, and for my part I was thoroughly at sea and
+could make nothing out of it all.
+
+"What object can such a man as Dr. Vaughn possibly have in frequenting
+such a place?" I asked at length, adding, "And there's that Mrs.
+Langhorne--she was interesting, too."
+
+Kennedy made no direct reply. "I shall have them shadowed to-morrow,"
+he said briefly, "while I am at work in the laboratory over this
+ampoule."
+
+As usual, also, Craig had begun on his scientific studies long before I
+was able to shake myself loose from the nightmares that haunted me
+after our weird experience of the evening.
+
+He had already given the order to an agency for the shadowing, and his
+next move was to start me out, also, looking into the history of those
+concerned in the case. As far as I was able to determine, Dr. Vaughn
+had an excellent reputation, and I could find no reason whatever for
+his connection with anything of the nature of the Red Lodge. The
+Rapports seemed to be nearly unknown in New York, although it was
+reported that they had come from Paris lately. Mrs. Langhorne was a
+divorcee from one of the western states, but little was known about
+her, except that she always seemed to be well supplied with money. It
+seemed to be well known in the circle in which Seward Blair moved that
+he was friendly with her, and I had about reached the conclusion that
+she was unscrupulously making use of his friendship, perhaps was not
+above such a thing as blackmail.
+
+Thus the day passed, and we heard no word from Veda Blair, although
+that was explained by the shadows, whose trails crossed in a most
+unexpected manner. Their reports showed that there was a meeting at the
+Red Lodge during the late afternoon, at which all had been present
+except Dr. Vaughn. We learned also from them the exact location of the
+Lodge, in an old house just across the line in Westchester.
+
+It was evidently a long and troublesome analysis that Craig was engaged
+in at the laboratory, for it was some hours after dinner that night
+when he came into the apartment, and even then he said nothing, but
+buried himself in some of the technical works with which his library
+was stocked. He said little, but I gathered that he was in great doubt
+about something, perhaps, as much as anything, about how to proceed
+with so peculiar a case.
+
+It was growing late, and Kennedy was still steeped in his books, when
+the door of the apartment, which we happened to have left unlocked, was
+suddenly thrown open and Seward Blair burst in on us, wildly excited.
+
+"Veda is gone!" he cried, before either of us could ask him what was
+the matter.
+
+"Gone?" repeated Kennedy. "How--where?"
+
+"I don't know," Blair blurted out breathlessly. "We had been out
+together this afternoon, and I returned with her. Then I went out to
+the club after dinner for a while, and when I got back I missed
+her--not quarter of an hour ago. I burst into her room--and there I
+found this note. Read it. I don't know what to do. No one seems to know
+what has become of her. I've called up all over and then thought
+perhaps you might help me, might know some friend of hers that I don't
+know, with whom she might have gone out."
+
+Blair was plainly eager for us to help him. Kennedy took the paper from
+him. On it, in a trembling hand, were scrawled some words, evidently
+addressed to Blair himself:
+
+"You would forgive me and pity me if you knew what I have been through.
+
+"When I refused to yield my will to the will of the Lodge I suppose I
+aroused the enmity of the Lodge.
+
+"To-night as I lay in bed, alone, I felt that my hour had come, that
+mental forces that were almost irresistible were being directed against
+me.
+
+"I realized that I must fight not only for my sanity but for my life.
+
+"For hours I have fought that fight.
+
+"But during those hours, some one, I won't say who, seemed to have
+developed such psychic faculties of penetration that they were able to
+make their bodies pass through the walls of my room.
+
+"At last I am conquered. I pray that you--"
+
+The writing broke off abruptly, as if she had left it in wild flight.
+
+"What does that mean?" asked Kennedy, "the 'will of the Lodge'?"
+
+Blair looked at us keenly. I fancied that there was even something
+accusatory in the look. "Perhaps it was some mental reservation on her
+part," he suggested. "You do not know yourself of any reason why she
+should fear anything, do you?" he asked pointedly.
+
+Kennedy did not betray even by the motion of an eyelash that we knew
+more than we should ostensibly.
+
+There was a tap at the door. I sprang to open it, thinking perhaps,
+after all, it was Veda herself.
+
+Instead, a man, a stranger, stood there.
+
+"Is this Professor Kennedy?" he asked, touching his hat.
+
+Craig nodded.
+
+"I am from the psychopathic ward of the City Hospital--an orderly,
+sir," the man introduced.
+
+"Yes," encouraged Craig, "what can I do for you?"
+
+"A Mrs. Blair has just been brought in, sir, and we can't find her
+husband. She's calling for you now."
+
+Kennedy stared from the orderly to Seward Blair, startled, speechless.
+
+"What has happened?" asked Blair anxiously. "I am Mr. Blair."
+
+The orderly shook his head. He had delivered his message. That was all
+he knew.
+
+"What do you suppose it is?" I asked, as we sped across town in a
+taxicab. "Is it the curse that she dreaded?"
+
+Kennedy said nothing and Blair appeared to hear nothing. His face was
+drawn in tense lines.
+
+The psychopathic ward is at once one of the most interesting and one of
+the most depressing departments of a large city hospital, harboring, as
+it does, all from the more or less harmless insane to violent
+alcoholics and wrecked drug fiends.
+
+Mrs. Blair, we learned, had been found hatless, without money, dazed,
+having fallen, after an apparently aimless wandering in the streets.
+
+For the moment she lay exhausted on the white bed of the ward, eyes
+glazed, pupils contracted, pulse now quick, now almost evanescent, face
+drawn, breathing difficult, moaning now and then in physical and mental
+agony.
+
+Until she spoke it was impossible to tell what had happened, but the
+ambulance surgeon had found a little red mark on her white forearm and
+had pointed it out, evidently with the idea that she was suffering from
+a drug.
+
+At the mere sight of the mark, Blair stared as though hypnotized.
+Leaning over to Kennedy, so that the others could not hear, he
+whispered, "It is the mark of the serpent!"
+
+Our arrival had been announced to the hospital physician, who entered
+and stood for a moment looking at the patient.
+
+"I think it is a drug--a poison," he said meditatively.
+
+"You haven't found out yet what it is, then?" asked Craig.
+
+The physician shook his head doubtfully. "Whatever it is," he said
+slowly, "it is closely allied to the cyanide groups in its rapacious
+activity. I haven't the slightest idea of its true nature, but it seems
+to have a powerful affinity for important nerve centers of respiration
+and muscular coordination, as well as for disorganizing the blood. I
+should say that it produces death by respiratory paralysis and
+convulsions. To my mind it is an exact, though perhaps less active,
+counterpart of hydrocyanic acid."
+
+Kennedy had been listening intently at the start, but before the
+physician had finished he had bent over and made a ligature quickly
+with his handkerchief.
+
+Then he dispatched a messenger with a note. Next he cut about the
+minute wound on her arm until the blood flowed, cupping it to increase
+the flow. Now and then he had them administer a little stimulant.
+
+He had worked rapidly, while Blair watched him with a sort of
+fascination.
+
+"Get Dr. Vaughn," ordered Craig, as soon as he had a breathing spell
+after his quick work, adding, "and Professor and Madame Rapport.
+Walter, attend to that, will you? I think you will find an officer
+outside. You'll have to compel them to come, if they won't come
+otherwise," he added, giving the address of the Lodge, as we had found
+it.
+
+Blair shot a quick look at him, as though Craig in his knowledge were
+uncanny. Apparently, the address had been a secret which he thought we
+did not know.
+
+I managed to find an officer and dispatch him for the Rapports. A
+hospital orderly, I thought, would serve to get Dr. Vaughn.
+
+
+
+
+CHAPTER XXIV
+
+THE SERPENT'S TOOTH
+
+
+I had scarcely returned to the ward when, suddenly, an unnatural
+strength seemed to be infused into Veda.
+
+She had risen in bed.
+
+"It shall not catch me!" she cried in a new paroxysm of nameless
+terror. "No--no--it is pursuing me. I am never out of its grasp. I have
+been thought six feet underground--I know it. There it is again--still
+driving me--still driving me!
+
+"Will it never stop? Will no one stop it? Save me! It--is the death
+thought!"
+
+She had risen convulsively and had drawn back in abject, cowering
+terror. What was it she saw? Evidently it was very real and very awful.
+It pursued her relentlessly.
+
+As she lay there, rolling her eyes about, she caught sight of us and
+recognized us for the first time, although she had been calling for us.
+
+"They had the thought on you, too, Professor Kennedy," she almost
+screamed. "Hour after hour, Rapport and the rest repeated over and over
+again, 'Why does not some one kill him? Why does he not die?' They knew
+you--even when I brought you to the Red Lodge. They thought you were a
+spy."
+
+I turned to Kennedy. He had advanced and was leaning over to catch
+every word. Blair was standing behind me and she had not seen her
+husband yet. A quick glance showed me that he was trembling from head
+to foot like a leaf, as though he, too, were pursued by the nameless
+terror.
+
+"What did they do?" Kennedy asked in a low tone.
+
+Fearfully, gripping the bars of the iron bed, as though they were some
+tangible support for her mind, she answered: "They would get together.
+'Now, all of you,' they said, 'unite yourselves in thought against our
+enemy, against Kennedy, that he must leave off persecuting us. He is
+ripe for destruction!'"
+
+Kennedy glanced sidewise at me, with a significant look.
+
+"God grant," she implored, "that none haunt me for what I have done in
+my ignorance!"
+
+Just then the door opened and my messenger entered, accompanied by Dr.
+Vaughn.
+
+I had turned to catch the expression on Blair's face just in time. It
+was a look of abject appeal.
+
+Before Dr. Vaughn could ask a question, or fairly take in the
+situation, Kennedy had faced him.
+
+"What was the purpose of all that elaborate mummery out at the Red
+Lodge?" asked Kennedy pointblank.
+
+I think I looked at Craig in no less amazement than Vaughn. In spite of
+the dramatic scenes through which we had passed, the spell of the
+occult had not fallen on him for an instant.
+
+"Mummery?" repeated Dr. Vaughn, bending his penetrating eyes on
+Kennedy, as if he would force him to betray himself first.
+
+"Yes," reiterated Craig. "You know as well as I do that it has been
+said that it is a well-established fact that the world wants to be
+deceived and is willing to pay for the privilege."
+
+Dr. Vaughn still gazed from one to the other of us defiantly.
+
+"You know what I mean," persisted Kennedy, "the mumbo-jumbo--just as
+the Haitian obi man sticks pins in a doll or melts a wax figure of his
+enemy. That is supposed to be an outward sign. But back of this
+terrible power that people believe moves in darkness and mystery is
+something tangible--something real."
+
+Dr. Vaughn looked up sharply at him, I think mistaking Kennedy's
+meaning. If he did, all doubt that Kennedy attributed anything to the
+supernatural was removed as he went on: "At first I had no explanation
+of the curious events I have just witnessed, and the more I thought
+about them, the more obscure did they seem.
+
+"I have tried to reason the thing out," he continued thoughtfully. "Did
+auto-suggestion, self-hypnotism explain what I have seen? Has Veda
+Blair been driven almost to death by her own fears only?"
+
+No one interrupted and he answered his own question. "Somehow the idea
+that it was purely fear that had driven her on did not satisfy me. As I
+said, I wanted something more tangible. I could not help thinking that
+it was not merely subjective. There was something objective, some force
+at work, something more than psychic in the result achieved by this
+criminal mental marauder, whoever it is."
+
+I was following Kennedy's reasoning now closely. As he proceeded, the
+point that he was making seemed more clear to me.
+
+Persons of a certain type of mind could be really mentally unbalanced
+by such methods which we had heard outlined, where the mere fact of
+another trying to exert power over them became known to them. They
+would, as a matter of fact, unbalance themselves, thinking about and
+fighting off imaginary terrors.
+
+Such people, I could readily see, might be quickly controlled, and in
+the wake of such control would follow stifled love, wrecked homes,
+ruined fortunes, suicide and even death.
+
+Dr. Vaughn leaned forward critically. "What did you conclude, then, was
+the explanation of what you saw last night?" he asked sharply.
+
+Kennedy met his question squarely, without flinching. "It looks to me,"
+he replied quietly, "like a sort of hystero-epilepsy. It is well known,
+I believe, to demonologists--those who have studied this sort of thing.
+They have recognized the contortions, the screams, the wild,
+blasphemous talk, the cataleptic rigidity. They are epileptiform."
+
+Vaughn said nothing, but continued to weigh Kennedy as if in a balance.
+I, who knew him, knew that it would take a greater than Vaughn to find
+him wanting, once Kennedy chose to speak. As for Vaughn, was he trying
+to hide behind some technicality in medical ethics?
+
+"Dr. Vaughn," continued Craig, as if goading him to the point of
+breaking down his calm silence, "you are specialist enough to know
+these things as well, better than I do. You must know that epilepsy is
+one of the most peculiar diseases.
+
+"The victim may be in good physical condition, apparently. In fact,
+some hardly know that they have it. But it is something more than
+merely the fits. Always there is something wrong mentally. It is not
+the motor disturbance so much as the disturbance of consciousness."
+
+Kennedy was talking slowly, deliberately, so that none could drop a
+link in the reasoning.
+
+"Perhaps one in ten epileptics has insane periods, more or less," he
+went on, "and there is no more dangerous form of insanity.
+Self-consciousness is lost, and in this state of automatism the worst
+of crimes have been committed without the subsequent knowledge of the
+patient. In that state they are no more responsible than are the actors
+in one's dreams."
+
+The hospital physician entered, accompanied by Craig's messenger,
+breathless. Craig almost seized the package from his hands and broke
+the seal.
+
+"Ah--this is what I wanted," he exclaimed, with an air of relief,
+forgetting for the time the exposition of the case that he was engaged
+in. "Here I have some anti-crotalus venine, of Drs. Flexner and
+Noguchi. Fortunately, in the city it is within easy reach."
+
+Quickly, with the aid of the physician he injected it into Veda's arm.
+
+"Of all substances in nature," he remarked, still at work over the
+unfortunate woman, "none is so little known as the venom of serpents."
+
+It was a startling idea which the sentence had raised in my mind. All
+at once I recalled the first remark of Seward Blair, in which he had
+repeated the password that had admitted us into the Red Lodge--"the
+Serpent's Tooth." Could it have been that she had really been bitten at
+some of the orgies by the serpent which they worshiped hideously
+hissing in its cage? I was sure that, at least until they were
+compelled, none would say anything about it. Was that the
+interpretation of the almost hypnotized look on Blair's face?
+
+"We know next to nothing of the composition of the protein bodies in
+the venoms which have such terrific, quick physiological effects,"
+Kennedy was saying. "They have been studied, it is true, but we cannot
+really say that they are understood--or even that there are any
+adequate tests by which they can be recognized. The fact is, that snake
+venoms are about the safest of poisons for the criminal."
+
+Kennedy had scarcely propounded this startling idea when a car was
+heard outside. The Rapports had arrived, with the officer I had sent
+after them, protesting and threatening.
+
+They quieted down a bit as they entered, and after a quick glance
+around saw who was present.
+
+Professor Rapport gave one glance at the victim lying exhausted on the
+bed, then drew back, melodramatically, and cried, "The Serpent--the
+mark of the serpent!"
+
+For a moment Kennedy gazed full in the eyes of them all.
+
+"WAS it a snake bite?" he asked slowly, then, turning to Mrs. Blair,
+after a quick glance, he went on rapidly, "The first thing to ascertain
+is whether the mark consists of two isolated punctures, from the
+poison-conducting teeth or fangs of the snake, which are constructed
+like a hypodermic needle."
+
+The hospital physician had bent over her at the words, and before
+Kennedy could go on interrupted: "This was not a snake bite; it was
+more likely from an all-glass hypodermic syringe with a
+platinum-iridium needle."
+
+Professor Rapport, priest of the Devil, advanced a step menacingly
+toward Kennedy. "Remember," he said in a low, angry tone,
+"remember--you are pledged to keep the secrets of the Red Lodge!"
+
+Craig brushed aside the sophistry with a sentence. "I do not recognize
+any secrets that I have to keep about the meeting this afternoon to
+which you summoned the Blairs and Mrs. Langhorne, according to reports
+from the shadows I had placed on Mrs. Langhorne and Dr. Vaughn."
+
+If there is such a thing as the evil eye, Rapport's must have been a
+pair of them, as he realized that Kennedy had resorted to the simple
+devices of shadowing the devotees.
+
+A cry, almost a shriek, startled us. Kennedy's encounter with Rapport
+had had an effect which none of us had considered. The step or two in
+advance which the prophet had taken had brought him into the line of
+vision of the still half-stupefied Veda lying back of Kennedy on the
+hospital cot.
+
+The mere sight of him, the sound of his voice and the mention of the
+Red Lodge had been sufficient to penetrate that stupor. She was sitting
+bolt upright, a ghastly, trembling specter. Slowly a smile seemed to
+creep over the cruel face of the mystic. Was it not a recognition of
+his hypnotic power?
+
+Kennedy turned and laid a gentle hand on the quaking convulsed figure
+of the woman. One could feel the electric tension in the air, the
+battle of two powers for good or evil. Which would win--the old
+fascination of the occult or the new power of science?
+
+It was a dramatic moment. Yet not so dramatic as the outcome. To my
+surprise, neither won.
+
+Suddenly she caught sight of her husband. Her face changed. All the
+prehistoric jealousy of which woman is capable seemed to blaze forth.
+
+"I will defend myself!" she cried. "I will fight back! She shall not
+win--she shall not have you--no--she shall not--never!"
+
+I recalled the strained feeling between the two women that I had
+noticed in the cab. Was it Mrs. Langhorne who had been the disturbing
+influence, whose power she feared, over herself and over her husband?
+
+Rapport had fallen back a step, but not from the mind of Kennedy.
+
+"Here," challenged Craig, facing the group and drawing from his pocket
+the glass ampoule, "I picked this up at the Red Lodge last night."
+
+He held it out in his hand before the Rapports so that they could not
+help but see it. Were they merely good actors? They betrayed nothing,
+at least by face or action.
+
+"It is crotalin," he announced, "the venom of the rattlesnake--crotalus
+horridus. It has been noticed that persons suffering from certain
+diseases of which epilepsy is one, after having been bitten by a
+rattlesnake, if they recover from the snake bite, are cured of the
+disease."
+
+Kennedy was forging straight ahead now in his exposure. "Crotalin," he
+continued, "is one of the new drugs used in the treatment of epilepsy.
+But it is a powerful two-edged instrument. Some one who knew the drug,
+who perhaps had used it, has tried an artificial bite of a rattler on
+Veda Blair, not for epilepsy, but for another, diabolical purpose,
+thinking to cover up the crime, either as the result of the so-called
+death thought of the Lodge or as the bite of the real rattler at the
+Lodge."
+
+Kennedy had at last got under Dr. Vaughn's guard. All his reticence was
+gone.
+
+"I joined the cult," he confessed. "I did it in order to observe and
+treat one of my patients for epilepsy. I justified myself. I said, 'I
+will be the exposer, not the accomplice, of this modern Satanism.' I
+joined it and--"
+
+"There is no use trying to shield anyone, Vaughn," rapped out Kennedy,
+scarcely taking time to listen. "An epileptic of the most dangerous
+criminal type has arranged this whole elaborate setting as a plot to
+get rid of the wife who brought him his fortune and now stands in the
+way of his unholy love of Mrs. Langhorne. He used you to get the poison
+with which you treated him. He used the Rapports with money to play on
+her mysticism by their so-called death thought, while he watched his
+opportunity to inject the fatal crotalin."
+
+Craig faced the criminal, whose eyes now showed more plainly than words
+his deranged mental condition, and in a low tone added, "The Devil is
+in you, Seward Blair!"
+
+
+
+
+CHAPTER XXV
+
+THE "HAPPY DUST"
+
+
+Veda Blair's rescue from the strange use that was made of the venom
+came at a time when the city was aroused as it never had been before
+over the nation-wide agitation against drugs.
+
+Already, it will be recalled, Kennedy and I had had some recent
+experience with dope fiends of various kinds, but this case I set down
+because it drew us more intimately into the crusade.
+
+"I've called on you, Professor Kennedy, to see if I can't interest you
+in the campaign I am planning against drugs."
+
+Mrs. Claydon Sutphen, social leader and suffragist, had scarcely more
+than introduced herself when she launched earnestly into the reason for
+her visit to us.
+
+"You don't realize it, perhaps," she continued rapidly, "but very often
+a little silver bottle of tablets is as much a necessary to some women
+of the smart set as cosmetics."
+
+"I've heard of such cases," nodded Craig encouragingly.
+
+"Well, you see I became interested in the subject," she added, "when I
+saw some of my own friends going down. That's how I came to plan the
+campaign in the first place."
+
+She paused, evidently nervous. "I've been threatened, too," she went
+on, "but I'm not going to give up the fight. People think that drugs
+are a curse only to the underworld, but they have no idea what inroads
+the habit has made in the upper world, too. Oh, it is awful!" she
+exclaimed.
+
+Suddenly, she leaned over and whispered, "Why, there's my own sister,
+Mrs. Garrett. She began taking drugs after an operation, and now they
+have a terrible hold on her. I needn't try to conceal anything. It's
+all been published in the papers--everybody knows it. Think of
+it--divorced, disgraced, all through these cursed drugs! Dr. Coleman,
+our family physician, has done everything known to break up the habit,
+but he hasn't succeeded."
+
+Dr. Coleman, I knew, was a famous society physician. If he had failed,
+I wondered why she thought a detective might succeed. But it was
+evidently another purpose she had in mind in introducing the subject.
+
+"So you can understand what it all means to me, personally," she
+resumed, with a sigh. "I've studied the thing--I've been forced to
+study it. Why, now the exploiters are even making drug fiends of
+mere--children!"
+
+Mrs. Sutphen spread out a crumpled sheet of note paper before us on
+which was written something in a trembling scrawl. "For instance,
+here's a letter I received only yesterday."
+
+Kennedy glanced over it carefully. It was signed "A Friend," and read:
+
+"I have heard of your drug war in the newspapers and wish to help you,
+only I don't dare to do so openly. But I can assure you that if you
+will investigate what I am about to tell you, you will soon be on the
+trail of those higher up in this terrible drug business. There is a
+little center of the traffic on West 66th Street, just off Broadway. I
+cannot tell you more, but if you can investigate it, you will be doing
+more good than you can possibly realize now. There is one girl there,
+whom they call 'Snowbird.' If you could only get hold of her quietly
+and place her in a sanitarium you might save her yet."
+
+Craig was more than ordinarily interested. "And the children--what did
+you mean by that?"
+
+"Why, it's literally true," asserted Mrs. Sutphen in a horrified tone.
+"Some of the victims are actually school children. Up there in 66th
+Street we have found a man named Armstrong, who seems to be very
+friendly with this young girl whom they call 'Snowbird.' Her real name,
+by the way, is Sawtelle, I believe. She can't be over eighteen, a mere
+child, yet she's a slave to the stuff."
+
+"Oh, then you have actually already acted on the hint in the letter?"
+asked Craig.
+
+"Yes," she replied, "I've had one of the agents of our Anti-Drug
+Society, a social worker, investigating the neighborhood."
+
+Kennedy nodded for her to go on.
+
+"I've even investigated myself a little, and now I want to employ some
+one to break the thing up. My husband had heard of you and so here I
+am. Can you help me?"
+
+There was a note of appeal in her voice that was irresistible to a man
+who had the heart of Kennedy.
+
+"Tell me just what you have discovered so far," he asked simply.
+
+"Well," she replied slowly, "after my agent verified the contents of
+the letter, I watched until I saw this girl--she's a mere child, as I
+said--going to a cabaret in the neighborhood. What struck me was that I
+saw her go in looking like a wreck and come out a beautiful creature,
+with bright eyes, flushed cheeks, almost youthful again. A most
+remarkable girl she is, too," mused Mrs. Sutphen, "who always wears a
+white gown, white hat, white shoes and white stockings. It must be a
+mania with her."
+
+Mrs. Sutphen seemed to have exhausted her small store of information,
+and as she rose to go Kennedy rose also. "I shall be glad to look into
+the case, Mrs. Sutphen," he promised. "I'm sure there is something that
+can be done--there must be."
+
+"Thank you, ever so much," she murmured, as she paused at the door,
+something still on her mind. "And perhaps, too," she added, "you may
+run across my sister, Mrs. Garrett."
+
+"Indeed," he assured her, "if there is anything I can possibly do that
+will assist you personally, I shall be only too happy to do it."
+
+"Thank you again, ever so much," she repeated with just a little choke
+in her voice.
+
+For several moments Kennedy sat contemplating the anonymous letter
+which she had left with him, studying both its contents and the
+handwriting.
+
+"We must go over the ground up there again," he remarked finally.
+"Perhaps we can do better than Mrs. Sutphen and her drug investigator
+have done."
+
+Half an hour later we had arrived and were sauntering along the street
+in question, walking slowly up and down in the now fast-gathering dusk.
+It was a typical cheap apartment block of variegated character, with
+people sitting idly on the narrow front steps and children spilling out
+into the roadway in imminent danger of their young lives from every
+passing automobile.
+
+On the crowded sidewalk a creation in white hurtled past us. One glance
+at the tense face in the flickering arc light was enough for Kennedy.
+He pulled my arm and we turned and followed at a safe distance.
+
+She looked like a girl who could not have been more than eighteen, if
+she was as old as that. She was pretty, too, but already her face was
+beginning to look old and worn from the use of drugs. It was
+unmistakable.
+
+In spite of the fact that she was hurrying, it was not difficult to
+follow her in the crowd, as she picked her way in and out, and finally
+turned into Broadway where the white lights were welcoming the night.
+
+Under the glare of a huge electric sign she stopped a moment, then
+entered one of the most notorious of the cabarets.
+
+We entered also at a discreet distance and sat down at a table.
+
+"Don't look around, Walter," whispered Craig, as the waiter took our
+order, "but to your right is Mrs. Sutphen."
+
+If he had mentioned any other name in the world, I could not have been
+more surprised. I waited impatiently until I could pick her out from
+the corner of my eye. Sure enough, it was Mrs. Sutphen and another
+woman. What they were doing there I could not imagine, for neither had
+the look of habitues of such a place.
+
+I followed Kennedy's eye and found that he was gazing furtively at a
+flashily dressed young man who was sitting alone at the far end in a
+sort of booth upholstered in leather.
+
+The girl in white, whom I was now sure was Miss Sawtelle, went over and
+greeted him. It was too far to see just what happened, but the young
+woman after sitting down rose and left almost immediately. As nearly as
+I could make out, she had got something from him which she had dropped
+into her handbag and was now hugging the handbag close to herself
+almost as if it were gold.
+
+We sat for a few minutes debating just what to do, when Mrs. Sutphen
+and her friend rose. As she passed out, a quick, covert glance told us
+to follow. We did so and the two turned into Broadway.
+
+"Let me present you to Miss McCann," introduced Mrs. Sutphen as we
+caught up with them. "Miss McCann is a social worker and trained
+investigator whom I'm employing."
+
+We bowed, but before we could ask a question, Mrs. Sutphen cried
+excitedly: "I think I have a clue, anyway. We've traced the source of
+the drugs at least as far as that young fellow, 'Whitecap,' whom you
+saw in there."
+
+I had not recognized his face, although I had undoubtedly seen pictures
+of him before. But no sooner had I heard the name than I recognized it
+as that of one of the most notorious gang leaders on the West Side.
+
+Not only that, but Whitecap's gang played an important part in local
+politics. There was scarcely a form of crime or vice to which Whitecap
+and his followers could not turn a skilled hand, whether it was
+swinging an election, running a gambling club, or dispensing "dope."
+
+"You see," she explained, "even before I saw you, my suspicions were
+aroused and I determined to obtain some of the stuff they are using up
+here, if possible. I realized it would be useless for me to try to get
+it myself, so I got Miss McCann from the Neighborhood House to try it.
+She got it and has turned the bottle over to me."
+
+"May I see it?" asked Craig eagerly.
+
+Mrs. Sutphen reached hastily into her handbag, drew forth a small brown
+glass bottle and handed it to him. Craig retreated into one of the less
+dark side streets. There he pulled out the paraffinned cork from the
+bottle, picked out a piece of cotton stuffed in the neck of the bottle
+and poured out some flat tablets that showed a glistening white in the
+palm of his hand. For an instant he regarded them.
+
+"I may keep these?" he asked.
+
+"Certainly," replied Mrs. Sutphen. "That's what I had Miss McCann get
+them for."
+
+Kennedy dropped the bottle into his pocket.
+
+"So that was the gang leader, 'Whitecap,'" he remarked as we turned
+again to Broadway.
+
+"Yes," replied Mrs. Sutphen. "At certain hours, I believe he can be
+found at that cabaret selling this stuff, whatever it is, to anyone who
+comes properly introduced. The thing seems to be so open and notorious
+that it amounts to a scandal."
+
+We parted a moment later, Mrs. Sutphen and Miss McCann to go to the
+settlement house, Craig and I to continue our investigations.
+
+"First of all, Walter," he said as we swung aboard an uptown car, "I
+want to stop at the laboratory."
+
+In his den, which had been the scene of so many triumphs, Kennedy began
+a hasty examination of the tablets, powdering one and testing it with
+one chemical after another.
+
+"What are they?" I asked at length when he seemed to have found the
+right reaction which gave him the clue.
+
+"Happy dust," he answered briefly.
+
+"Happy dust?" I repeated, looking at him a moment in doubt as to
+whether he was joking or serious. "What is that?"
+
+"The Tenderloin name for heroin--a comparatively new derivative of
+morphine. It is really morphine treated with acetic acid which renders
+it more powerful than morphine alone."
+
+"How do they take them? What's the effect?" I asked.
+
+"The person who uses heroin usually powders the tablets and snuffs the
+powder up the nose," he answered. "In a short time, perhaps only two or
+three weeks, one can become a confirmed victim of 'happy dust.' And
+while one is under its influence he is morally, physically and mentally
+irresponsible."
+
+Kennedy was putting away the paraphernalia he had used, meanwhile
+talking about the drug. "One of the worst aspects of it, too," he
+continued, "is the desire of the user to share his experience with some
+one else. This passing on of the habit, which seems to be one of the
+strongest desires of the drug fiend, makes him even more dangerous to
+society than he would otherwise be. It makes it harder for anyone once
+addicted to a drug to shake it off, for his friends will give him no
+chance. The only thing to do is to get the victim out of his
+environment and into an entirely new scene."
+
+The laboratory table cleared again, Kennedy had dropped into a deep
+study.
+
+"Now, why was Mrs. Sutphen there?" he asked aloud. "I can't think it
+was solely through her interest for that girl they call Snowbird. She
+was interested in her, but she made no attempt to interfere or to
+follow her. No, there must have been another reason."
+
+"You don't think she's a dope fiend herself, do you?" I asked hurriedly.
+
+Kennedy smiled. "Hardly, Walter. If she has any obsession on the
+subject, it is more likely to lead her to actual fanaticism against all
+stimulants and narcotics and everything connected with them. No, you
+might possibly persuade me that two and two equal five--but not
+seventeen. It's not very late. I think we might make another visit to
+that cabaret and see whether the same thing is going on yet."
+
+
+
+
+CHAPTER XXVI
+
+THE BINET TEST
+
+
+We rode downtown again and again sauntered in, this time with the
+theater crowd. Our first visit had been so quiet and unostentatious
+that the second attracted no attention or comment from the waiters, or
+anyone else.
+
+As we sat down we glanced over, and there in his corner still was
+Whitecap. Apparently his supply of the dope was inexhaustible, for he
+was still dispensing it. As we watched the tenderloin habitues come and
+go, I came soon to recognize the signs by the mere look on the
+face--the pasty skin, the vacant eye, the nervous quiver of the muscles
+as though every organ and every nerve were crying out for more of the
+favorite nepenthe. Time and again I noticed the victims as they sat at
+the tables, growing more and more haggard and worn, until they could
+stand it no longer. Then they would retire, sometimes after a visit
+across the floor to Whitecap, more often directly, for they had stocked
+themselves up with the drug evidently after the first visit to him. But
+always they would come back, changed in appearance, with what seemed to
+be a new lease of life, but nevertheless still as recognizable as drug
+victims.
+
+It was not long, as we waited, before another woman, older than Miss
+Sawtelle, but dressed in an extreme fashion, hurried into the cabaret
+and with scarcely a look to right or left went directly to Whitecap's
+corner. I noticed that she, too, had the look.
+
+There was a surreptitious passing of a bottle in exchange for a
+treasury note, and she dropped into the seat beside him.
+
+Before he could interfere, she had opened the bottle, crushed a tablet
+or two in a napkin, and was holding it to her face as though breathing
+the most exquisite perfume. With one quick inspiration of her breath
+after another, she was snuffing the powder up her nose.
+
+Whitecap with an angry gesture pulled the napkin from her face, and one
+could fancy his snarl under his breath, "Say--do you want to get me in
+wrong here?"
+
+But it was too late. Some at least of the happy dust had taken effect,
+at least enough to relieve the terrible pangs she must have been
+suffering.
+
+As she rose and retired, with a hasty apology to Whitecap for her
+indiscretion, Kennedy turned to me and exclaimed, "Think of it. The
+deadliest of all habits is the simplest. No hypodermic; no pipe; no
+paraphernalia of any kind. It's terrible."
+
+She returned to sit down and enjoy herself, careful not to obtrude
+herself on Whitecap lest he might become angry at the mere sight of her
+and treasure his anger up against the next time when she would need the
+drug.
+
+Already there was the most marvelous change in her. She seemed
+captivated by the music, the dancing, the life which a few moments
+before she had totally disregarded.
+
+She was seated alone, not far from us, and as she glanced about Kennedy
+caught her eye. She allowed her gaze to rest on us for a moment, the
+signal for a mild flirtation which ended in our exchange of tables and
+we found ourselves opposite the drug fiend, who was following up the
+taking of the dope by a thin-stemmed glass of a liqueur.
+
+I do not recall the conversation, but it was one of those
+inconsequential talks that Bohemians consider so brilliant and
+everybody else so vapid. As we skimmed from one subject to another,
+treating the big facts of life as if they were mere incidents and the
+little as if they overshadowed all else, I could see that Craig, who
+had a faculty of probing into the very soul of anyone, when he chose,
+was gradually leading around to a subject which I knew he wanted, above
+all others, to discuss.
+
+It was not long before, as the most natural remark in the world
+following something he had made her say, just as a clever
+prestidigitator forces a card, he asked, "What was it I saw you
+snuffing over in the booth--happy dust?"
+
+She did not even take the trouble to deny it, but nodded a brazen
+"Yes." "How did you come to use it first?" he asked, careful not to
+give offense in either tone or manner.
+
+"The usual way, I suppose," she replied with a laugh that sounded harsh
+and grating. "I was ill and I found out what it was the doctor was
+giving me."
+
+"And then?"
+
+"Oh, I thought I would use it only as long as it served my purpose and,
+when that was over, give it up."
+
+"But--?" prompted Craig hypnotically.
+
+"Instead, I was soon using six, eight, ten tablets of heroin a day. I
+found that I needed that amount in order to live. Then it went up by
+leaps to twenty, thirty, forty."
+
+"Suppose you couldn't get it, what then?"
+
+"Couldn't get it?" she repeated with an unspeakable horror. "Once I
+thought I'd try to stop. But my heart skipped beats; then it seemed to
+pound away, as if trying to break through my ribs. I don't think heroin
+is like other drugs. When one has her 'coke'--that's cocaine--taken
+away, she feels like a rag. Fill her up and she can do anything again.
+But, heroin--I think one might murder to get it!"
+
+The expression on the woman's face was almost tragic. I verily believe
+that she meant it.
+
+"Why," she cried, "if anyone had told me a year ago that the time would
+ever come when I would value some tiny white tablets above anything
+else in the world, yes, and even above my immortal soul, I would have
+thought him a lunatic."
+
+It was getting late, and as the woman showed no disposition to leave,
+Kennedy and I excused ourselves.
+
+Outside Craig looked at me keenly. "Can you guess who that was?"
+
+"Although she didn't tell us her name," I replied, "I am morally
+certain that it was Mrs. Garrett."
+
+"Precisely," he answered, "and what a shame, too, for she must
+evidently once have been a woman of great education and refinement."
+
+He shook his head sadly. "Walter, there isn't likely to be anything
+that we can do for some hours now. I have a little experiment I'd like
+to make. Suppose you publish for me a story in the Star about the
+campaign against drugs. Tell about what we have seen to-night, mention
+the cabaret by indirection and Whitecap directly. Then we can sit back
+and see what happens. We've got to throw a scare into them somehow, if
+we are going to smoke out anyone higher up than Whitecap. But you'll
+have to be careful, for if they suspect us our usefulness in the case
+will be over."
+
+Together, Kennedy and I worked over our story far into the night down
+at the Star office, and the following day waited to see whether
+anything came of it.
+
+It was with a great deal of interest tempered by fear that we dropped
+into the cabaret the following evening. Fortunately no one suspected
+us. In fact, having been there the night before, we had established
+ourselves, as it were, and were welcomed as old patrons and good
+spenders.
+
+I noticed, however, that Whitecap was not there. The story had been
+read by such of the dope fiends as had not fallen too far to keep
+abreast of the times and these and the waiters were busy quietly
+warning off a line of haggard-eyed, disappointed patrons who came
+around, as usual.
+
+Some of them were so obviously dependent on Whitecap that I almost
+regretted having written the story, for they must have been suffering
+the tortures of the damned.
+
+It was in the midst of a reverie of this sort that a low exclamation
+from Kennedy recalled my attention. There was Snowbird with a man
+considerably older than herself. They had just come in and were looking
+about frantically for Whitecap. But Whitecap had been too frightened by
+the story in the Star to sell any more of the magic happy dust openly
+in the cabaret, at least.
+
+The pair, nerve-racked and exhausted, sat down mournfully in a seat
+near us, and as they talked earnestly in low tones we had an excellent
+opportunity for studying Armstrong for the first time.
+
+He was not a bad-looking man, or even a weak one. In back of the
+dissipation of the drugs one fancied he could read the story of a
+brilliant life wrecked. But there was little left to admire or respect.
+As the couple talked earnestly, the one so old, the other so young in
+vice, I had to keep a tight rein on myself to prevent my sympathy for
+the wretched girl getting the better of common sense and kicking the
+older man out of doors.
+
+Finally Armstrong rose to go, with a final imploring glance from the
+girl. Obviously she had persuaded him to forage about to secure the
+heroin, by hook or crook, now that the accustomed source of supply was
+cut off so suddenly.
+
+It was also really our first chance to study the girl carefully under
+the light, for her entrance and exit the night before had been so
+hurried that we had seen comparatively little of her. Craig was
+watching her narrowly. Not only were the effects of the drug plainly
+evident on her face, but it was apparent that the snuffing the powdered
+tablets was destroying the bones in her nose, through shrinkage of the
+blood vessels, as well as undermining the nervous system and causing
+the brain to totter.
+
+I was wondering whether Armstrong knew of any depot for the secret
+distribution of the drug. I could not believe that Whitecap was either
+the chief distributer or the financial head of the illegal traffic. I
+wondered who indeed was the man higher up. Was he an importer of the
+drug, or was he the representative of some chemical company not averse
+to making an illegal dollar now and then by dragging down his fellow
+man?
+
+Kennedy and I were trying to act as if we were enjoying the cabaret
+show and not too much interested in the little drama that was being
+acted before us. I think little Miss Sawtelle noticed, however, that we
+were looking often her way. I was amazed, too, on studying her more
+closely to find that there was something indefinably queer about her,
+aside from the marked effect of the drugs she had been taking. What it
+was I was at a loss to determine, but I felt sure from the expression
+on Kennedy's face that he had noticed it also.
+
+I was on the point of asking him if he, too, observed anything queer in
+the girl, when Armstrong hurried in and handed her a small package,
+then almost without a word stalked out again, evidently as much to
+Snowbird's surprise as to our own.
+
+She had literally seized the package, as though she were drowning and
+grasping at a life buoy. Even the surprise at his hasty departure could
+not prevent her, however, from literally tearing the wrapper off, and
+in the sheltering shadow of the table cloth pouring forth the little
+white pellets in her lap, counting them as a miser counts his gold,
+
+"The old thief!" she exclaimed aloud. "He's held out twenty-five!"
+
+I don't know which it was that amazed me most, the almost childish
+petulance and ungovernable temper of the girl which made her cry out in
+spite of her surroundings and the circumstances, or the petty rapacity
+of the man who could stoop to such a low level as to rob her in this
+seeming underhand manner.
+
+There was no time for useless repining now. The call of outraged nature
+for its daily and hourly quota of poison was too imperative. She dumped
+the pellets back into the bottle hastily, and disappeared.
+
+When she came back, it was with that expression I had come to know so
+well. At least for a few hours there was a respite for her from the
+terrific pangs she had been suffering. She was almost happy, smiling.
+Even that false happiness, I felt, was superior to Armstrong's moral
+sense blunted by drugs. I had begun to realize how lying, stealing,
+crimes of all sorts might be laid at the door of this great evil.
+
+In her haste to get where she could snuff the heroin she had forgotten
+a light wrap lying on her chair. As she returned for it, it fell to the
+floor. Instantly Kennedy was on his feet, bending over to pick it up.
+
+She thanked him, and the smile lingered a moment on her face. It was
+enough. It gave Kennedy the chance to pursue a conversation, and in the
+free and easy atmosphere of the cabaret to invite her to sit over at
+our table.
+
+At least all her nervousness was gone and she chatted vivaciously.
+Kennedy said little. He was too busy watching her. It was quite the
+opposite of the case of Mrs. Garrett. Yet I was at a loss to define
+what it was that I sensed.
+
+Still the minutes sped past and we seemed to be getting on famously.
+Unlike his action in the case of the older woman where he had been
+sounding the depths of her heart and mind, in this case his idea seemed
+to be to allow the childish prattle to come out and perhaps explain
+itself.
+
+However, at the end of half an hour when we seemed to be getting no
+further along, Kennedy did not protest at her desire to leave us, "to
+keep a date," as she expressed it.
+
+"Waiter, the check, please," ordered Kennedy leisurely.
+
+When he received it, he seemed to be in no great hurry to pay it, but
+went over one item after another, then added up the footing again.
+
+"Strange how some of these waiters grow rich?" Craig remarked finally
+with a gay smile.
+
+The idea of waiters and money quickly brought some petty reminiscences
+to her mind. While she was still talking, Craig casually pulled a
+pencil out of his pocket and scribbled some figures on the back of the
+waiter's check.
+
+From where I was sitting beside him, I could see that he had written
+some figures similar to the following:
+
+5183 47395 654726 2964375 47293815 924738651 2146073859
+
+"Here's a stunt," he remarked, breaking into the conversation at a
+convenient point. "Can you repeat these numbers after me?"
+
+Without waiting for her to make excuse, he said quickly "5183." "5183,"
+she repeated mechanically.
+
+"47395," came in rapid succession, to which she replied, perhaps a
+little slower than before,
+
+"47395."
+
+"Now, 654726," he said.
+
+"654726," she repeated, I thought with some hesitation.
+
+"Again, 2964375," he shot out.
+
+"269," she hesitated, "73--" she stopped.
+
+It was evident that she had reached the limit.
+
+Kennedy smiled, paid the check and we parted at the door.
+
+"What was all that rigmarole?" I inquired as the white figure
+disappeared down the street.
+
+"Part of the Binet test, seeing how many digits one can remember. An
+adult ought to remember from eight to ten, in any order. But she has
+the mentality of a child. That is the queer thing about her.
+Chronologically she may be eighteen years or so old. Mentally she is
+scarcely more than eight. Mrs. Sutphen was right. They have made a
+fiend out of a mere child--a defective who never had a chance against
+them."
+
+
+
+
+CHAPTER XXVII
+
+THE LIE DETECTOR
+
+
+As the horror of it all dawned on me, I hated Armstrong worse than
+ever, hated Whitecap, hated the man higher up, whoever he might be, who
+was enriching himself out of the defective, as well as the weakling,
+and the vicious--all three typified by Snowbird, Armstrong and Whitecap.
+
+Having no other place to go, pending further developments of the
+publicity we had given the drug war in the Star, Kennedy and I decided
+on a walk home in the bracing night air.
+
+We had scarcely entered the apartment when the hall boy called to us
+frantically: "Some one's been trying to get you all over town,
+Professor Kennedy. Here's the message. I wrote it down. An attempt has
+been made to poison Mrs. Sutphen. They said at the other end of the
+line that you'd know."
+
+We faced each other aghast.
+
+"My God!" exclaimed Kennedy. "Has that been the effect of our story,
+Walter? Instead of smoking out anyone--we've almost killed some one."
+
+As fast as a cab could whisk us around to Mrs. Sutphen's we hurried.
+
+"I warned her that if she mixed up in any such fight as this she might
+expect almost anything," remarked Mr. Sutphen nervously, as he met us
+in the reception room. "She's all right, now, I guess, but if it hadn't
+been for the prompt work of the ambulance surgeon I sent for, Dr.
+Coleman says she would have died in fifteen minutes."
+
+"How did it happen?" asked Craig.
+
+"Why, she usually drinks a glass of vichy and milk before retiring,"
+replied Mr. Sutphen. "We don't know yet whether it was the vichy or the
+milk that was poisoned, but Dr. Coleman thinks it was chloral in one or
+the other, and so did the ambulance surgeon. I tell you I was scared. I
+tried to get Coleman, but he was out on a case, and I happened to think
+of the hospitals as probably the quickest. Dr. Coleman came in just as
+the young surgeon was bringing her around. He--oh, here he is now."
+
+The famous doctor was just coming downstairs. He saw us, but, I
+suppose, inasmuch as we did not belong to the Sutphen and Coleman set,
+ignored us. "Mrs. Sutphen will be all right now," he said reassuringly
+as he drew on his gloves. "The nurse has arrived, and I have given her
+instructions what to do. And, by the way, my dear Sutphen, I should
+advise you to deal firmly with her in that matter about which her name
+is appearing in the papers. Women nowadays don't seem to realize the
+dangers they run in mixing in in all these reforms. I have ordered an
+analysis of both the milk and vichy, but that will do little good
+unless we can find out who poisoned it. And there are so many chances
+for things like that, life is so complex nowadays--"
+
+He passed out with scarcely a nod at us. Kennedy did not attempt to
+question him. He was thinking rapidly.
+
+"Walter, we have no time to lose," he exclaimed, seizing a telephone
+that stood on a stand near by. "This is the time for action.
+Hello--Police Headquarters, First Deputy O'Connor, please."
+
+As Kennedy waited I tried to figure out how it could have happened. I
+wondered whether it might not have been Mrs. Garrett. Would she stop at
+anything if she feared the loss of her favorite drug? But then there
+were so many others and so many ways of "getting" anybody who
+interfered with the drug traffic that it seemed impossible to figure it
+out by pure deduction.
+
+"Hello, O'Connor," I heard Kennedy say; "you read that story in the
+Star this morning about the drug fiends at that Broadway cabaret? Yes?
+Well, Jameson and I wrote it. It's part of the drug war that Mrs.
+Sutphen has been waging. O'Connor, she's been poisoned--oh, no--she's
+all right now. But I want you to send out and arrest Whitecap and that
+fellow Armstrong immediately. I'm going to put them through a
+scientific third degree up in the laboratory to-night. Thank you.
+No--no matter how late it is, bring them up."
+
+Dr. Coleman had gone long since, Mr. Sutphen had absolutely no interest
+further than the recovery of Mrs. Sutphen just now, and Mrs. Sutphen
+was resting quietly and could not be seen. Accordingly Kennedy and I
+hastened up to the laboratory to wait until O'Connor could "deliver the
+goods."
+
+It was not long before one of O'Connor's men came in with Whitecap.
+
+"While we're waiting," said Craig, "I wish you would just try this
+little cut-out puzzle."
+
+I don't know what Whitecap thought, but I know I looked at Craig's
+invitation to "play blocks" as a joke scarcely higher in order than the
+number repetition of Snowbird. Whitecap did it, however, sullenly, and
+under compulsion, in, I should say about two minutes.
+
+"I have Armstrong here myself," called out the voice of our old friend
+O'Connor, as he burst into the room.
+
+"Good!" exclaimed Kennedy. "I shall be ready for him in just a second.
+Have Whitecap held here in the anteroom while you bring Armstrong into
+the laboratory. By the way, Walter, that was another of the Binet
+tests, putting a man at solving puzzles. It involves reflective
+judgment, one of the factors in executive ability. If Whitecap had been
+defective, it would have taken him five minutes to do that puzzle, if
+at all. So you see he is not in the class with Miss Sawtelle. The test
+shows him to be shrewd. He doesn't even touch his own dope. Now for
+Armstrong."
+
+I knew enough of the underworld to set Whitecap down, however, as a
+"lobbygow"--an agent for some one higher up, recruiting both the gangs
+and the ranks of street women.
+
+Before us, as O'Connor led in Armstrong, was a little machine with a
+big black cylinder. By means of wires and electrodes Kennedy attached
+it to Armstrong's chest.
+
+"Now, Armstrong," he began in an even tone, "I want you to tell the
+truth--the whole truth. You have been getting heroin tablets from
+Whitecap."
+
+"Yes, sir," replied the dope fiend defiantly.
+
+"To-day you had to get them elsewhere."
+
+No answer.
+
+"Never mind," persisted Kennedy, still calm, "I know. Why, Armstrong,
+you even robbed that girl of twenty-five tablets."
+
+"I did not," shot out the answer.
+
+"There were twenty-five short," accused Kennedy.
+
+The two faced each other. Craig repeated his remark.
+
+"Yes," replied Armstrong, "I held out the tablets, but it was not for
+myself, I can get all I want. I did it because I didn't want her to get
+above seventy-five a day. I have tried every way to break her of the
+habit that has got me--and failed. But seventy-five--is the limit!"
+
+"A pretty story!" exclaimed O'Connor.
+
+Craig laid his hand on his arm to check him, as he examined a record
+registered on the cylinder of the machine.
+
+"By the way, Armstrong, I want you to write me out a note that I can
+use to get a hundred heroin tablets. You can write it all but the name
+of the place where I can get them."
+
+Armstrong was on the point of demurring, but the last sentence
+reassured him. He would reveal nothing by it--yet.
+
+Still the man was trembling like a leaf. He wrote:
+
+"Give Whitecap one hundred shocks--A Victim."
+
+For a moment Kennedy studied the note carefully. "Oh--er--I forgot,
+Armstrong, but a few days ago an anonymous letter was sent to Mrs.
+Sutphen, signed 'A Friend.' Do you know anything about it?"
+
+"A note?" the man repeated. "Mrs. Sutphen? I don't know anything about
+any note, or Mrs. Sutphen either."
+
+Kennedy was still studying his record. "This," he remarked slowly, "is
+what I call my psychophysical test for falsehood. Lying, when it is
+practiced by an expert, is not easily detected by the most careful
+scrutiny of the liar's appearance and manner.
+
+"However, successful means have been developed for the detection of
+falsehood by the study of experimental psychology. Walter, I think you
+will recall the test I used once, the psychophysical factor of the
+character and rapidity of the mental process known as the association
+of ideas?"
+
+I nodded acquiescence.
+
+"Well," he resumed, "in criminal jurisprudence, I find an even more
+simple and more subjective test which has been recently devised.
+Professor Stoerring of Bonn has found out that feelings of pleasure and
+pain produce well-defined changes in respiration. Similar effects are
+produced by lying, according to the famous Professor Benussi of Graz.
+
+"These effects are unerring, unequivocal. The utterance of a false
+statement increases respiration; of a true statement decreases. The
+importance and scope of these discoveries are obvious."
+
+Craig was figuring rapidly on a piece of paper. "This is a certain and
+objective criterion," he continued as he figured, "between truth and
+falsehood. Even when a clever liar endeavors to escape detection by
+breathing irregularly, it is likely to fail, for Benussi has
+investigated and found that voluntary changes in respiration don't
+alter the result. You see, the quotient obtained by dividing the time
+of inspiration by the time of expiration gives me the result."
+
+He looked up suddenly. "Armstrong, you are telling the truth about some
+things--downright lies about others. You are a drug fiend--but I will
+be lenient with you, for one reason. Contrary to everything that I
+would have expected, you are really trying to save that poor
+half-witted girl whom you love from the terrible habit that has gripped
+you. That is why you held out the quarter of the one hundred tablets.
+That is why you wrote the note to Mrs. Sutphen, hoping that she might
+be treated in some institution."
+
+Kennedy paused as a look of incredulity passed over Armstrong's face.
+
+"Another thing you said was true," added Kennedy. "You can get all the
+heroin you want. Armstrong, you will put the address of that place on
+the outside of the note, or both you and Whitecap go to jail. Snowbird
+will be left to her own devices--she can get all the 'snow,' as some of
+you fiends call it, that she wants from those who might exploit her."
+
+"Please, Mr. Kennedy," pleaded Armstrong.
+
+"No," interrupted Craig, before the drug fiend could finish. "That is
+final. I must have the name of that place."
+
+In a shaky hand Armstrong wrote again. Hastily Craig stuffed the note
+into his pocket, and ten minutes later we were mounting the steps of a
+big brownstone house on a fashionable side street just around the
+corner from Fifth Avenue.
+
+As the door was opened by an obsequious colored servant, Craig handed
+him the scrap of paper signed by the password, "A Victim."
+
+Imitating the cough of a confirmed dope user, Craig was led into a
+large waiting room.
+
+"You're in pretty bad shape, sah," commented the servant.
+
+Kennedy nudged me and, taking the cue, I coughed myself red in the face.
+
+"Yes," he said. "Hurry--please."
+
+The servant knocked at a door, and as it was opened we caught a glimpse
+of Mrs. Garrett in negligee.
+
+"What is it, Sam?" she asked.
+
+"Two gentlemen for some heroin tablets, ma'am."
+
+"Tell them to go to the chemical works--not to my office, Sam," growled
+a man's voice inside.
+
+With a quick motion, Kennedy had Mrs. Garrett by the wrist.
+
+"I knew it," he ground out. "It was all a fake about how you got the
+habit. You wanted to get it, so you could get and hold him. And neither
+one of you would stop at anything, not even the murder of your sister,
+to prevent the ruin of the devilish business you have built up in
+manufacturing and marketing the stuff."
+
+He pulled the note from the hand of the surprised negro. "I had the
+right address, the place where you sell hundreds of ounces of the stuff
+a week--but I preferred to come to the doctor's office where I could
+find you both."
+
+Kennedy had firmly twisted her wrist until, with a little scream of
+pain, she let go the door handle. Then he gently pushed her aside, and
+the next instant Craig had his hand inside the collar of Dr. Coleman,
+society physician, proprietor of the Coleman Chemical Works downtown,
+the real leader of the drug gang that was debauching whole sections of
+the metropolis.
+
+
+
+
+CHAPTER XXVIII
+
+THE FAMILY SKELETON
+
+
+Surprised though we were at the unmasking of Dr. Coleman, there was
+nothing to do but to follow the thing out. In such cases we usually ran
+into the greatest difficulty--organized vice. This was no exception.
+
+Even when cases involved only a clever individual or a prominent
+family, it was the same. I recall, for example, the case of a
+well-known family in a New York suburb, which was particularly
+difficult. It began in a rather unusual manner, too.
+
+"Mr. Kennedy--I am ruined--ruined."
+
+It was early one morning that the telephone rang and I answered it. A
+very excited German, breathless and incoherent, was evidently at the
+other end of the wire.
+
+I handed the receiver to Craig and picked up the morning paper lying on
+the table.
+
+"Minturn--dead?" I heard Craig exclaim. "In the paper this morning?
+I'll be down to see you directly."
+
+Kennedy almost tore the paper from me. In the next to the end column
+where late news usually is dropped was a brief account of the sudden
+death of Owen Minturn, one of the foremost criminal lawyers of the
+city, in Josephson's Baths downtown.
+
+It ended: "It is believed by the coroner that Mr. Minturn was shocked
+to death and evidence is being sought to show that two hundred and
+forty volts of electricity had been thrown into the attorney's body
+while he was in the electric bath. Joseph Josephson, the proprietor of
+the bath, who operated the switchboard, is being held, pending the
+completion of the inquiry."
+
+As Kennedy hastily ran his eye over the paragraphs, he became more and
+more excited himself.
+
+"Walter," he cried, as he finished, "I don't believe that that was an
+accident at all."
+
+"Why?" I asked.
+
+He already had his hat on, and I knew he was going to Josephson's
+breakfastless. I followed reluctantly.
+
+"Because," he answered, as we hustled along in the early morning crowd,
+"it was only yesterday afternoon that I saw Minturn at his office and
+he made an appointment with me for this very morning. He was a very
+secretive man, but he did tell me this much, that he feared his life
+was in danger and that it was in some way connected with that Pearcy
+case up in Stratfield, Connecticut, where he has an estate. You have
+read of the case?"
+
+Indeed I had. It had seemed to me to be a particularly inexplicable
+affair. Apparently a whole family had been poisoned and a few days
+before old Mr. Randall Pearcy, a retired manufacturer, had died after a
+brief but mysterious illness.
+
+Pearcy had been married a year or so ago to Annette Oakleigh, a
+Broadway comic opera singer, who was his second wife. By his first
+marriage he had had two children, a son, Warner, and a daughter, Isabel.
+
+Warner Pearcy, I had heard, had blazed a vermilion trail along the
+Great White Way, but his sister was of the opposite temperament,
+interested in social work, and had attracted much attention by
+organizing a settlement in the slums of Stratfield for the uplift of
+the workers in the Pearcy and other mills.
+
+Broadway, as well as Stratfield, had already woven a fantastic
+background, for the mystery and hints had been broadly made that
+Annette Oakleigh had been indiscreetly intimate with a young physician
+in the town, a Dr. Gunther, a friend, by the way, of Minturn. "There
+has been no trial yet," went on Kennedy, "but Minturn seems to have
+appeared before the coroner's jury at Stratfield and to have asserted
+the innocence of Mrs. Pearcy and that of Dr. Gunther so well that,
+although the jury brought in a verdict of murder by poison by some one
+unknown, there has been no mention of the name of anyone else. The
+coroner simply adjourned the inquest so that a more careful analysis
+might be made of the vital organs. And now comes this second tragedy in
+New York."
+
+"What was the poison?" I asked. "Have they found out yet?"
+
+"They are pretty sure, so Minturn told me, that it was lead poisoning.
+The fact not generally known is," he added in a lower tone, "that the
+cases were not confined to the Pearcy house. They had even extended to
+Minturn's too, although about that he said little yesterday. The
+estates up there adjoin, you know."
+
+Owen Minturn, I recalled, had gained a formidable reputation by his
+successful handling of cases from the lowest strata of society to the
+highest. Indeed it was a byword that his appearance in court indicated
+two things--the guilt of the accused and a verdict of acquittal.
+
+"Of course," Craig pursued as we were jolted from station to station
+downtown, "you know they say that Minturn never kept a record of a
+case. But written records were as nothing compared to what that man
+must have carried only in his head."
+
+It was a common saying that, if Minturn should tell all he knew, he
+might hang half a dozen prominent men in society. That was not strictly
+true, perhaps, but it was certain that a revelation of the things
+confided to him by clients which were never put down on paper would
+have caused a series of explosions that would have wrecked at least
+some portions of the social and financial world. He had heard much and
+told little, for he had been a sort of "father confessor."
+
+Had Minturn, I wondered, known the name of the real criminal?
+
+Josephson's was a popular bath on Forty-second Street, where many of
+the "sun-dodgers" were accustomed to recuperate during the day from
+their arduous pursuit of pleasure at night and prepare for the
+resumption of their toil during the coming night. It was more than
+that, however, for it had a reputation for being conducted really on a
+high plane.
+
+We met Josephson downstairs. He had been released under bail, though
+the place was temporarily closed and watched over by the agents of the
+coroner and the police. Josephson appeared to be a man of some
+education and quite different from what I had imagined from hearing him
+over the telephone.
+
+"Oh, Mr. Kennedy," he exclaimed, "who now will come to my baths? Last
+night they were crowded, but to-day--"
+
+He ended with an expressive gesture of his hands.
+
+"One customer I have surely lost, young Mr. Pearcy," he went on.
+
+"Warner Pearcy?" asked Craig. "Was he here last night?"
+
+"Nearly every night," replied Josephson, now glib enough as his first
+excitement subsided and his command of English returned. "He was a
+neighbor of Mr. Minturn's, I hear. Oh, what luck!" growled Josephson as
+the name recalled him to his present troubles.
+
+"Well," remarked Kennedy with an attempt at reassurance as if to gain
+the masseur's confidence, "I know as well as you that it is often
+amazing what a tremendous shock a man may receive and yet not be
+killed, and no less amazing how small a shock may kill. It all depends
+on circumstances."
+
+Josephson shot a covert look at Kennedy. "Yes," he reiterated, "but I
+cannot see how it COULD be. If the lights had become short-circuited
+with the bath, that might have thrown a current into the bath. But they
+were not. I know it."
+
+"Still," pursued Kennedy, watching him keenly, "it is not all a
+question of current. To kill, the shock must pass through a vital
+organ--the brain, the heart, the upper spinal cord. So, a small shock
+may kill and a large one may not. If it passes in one foot and out by
+the other, the current isn't likely to be as dangerous as if it passes
+in by a hand or foot and then out by a foot or hand. In one case it
+passes through no vital organ; in the other it is very likely to do so.
+You see, the current can flow through the body only when it has a place
+of entrance and a place of exit. In all cases of accident from electric
+light wires, the victim is touching some conductor--damp earth, salty
+earth, water, something that gives the current an outlet and--"
+
+"But even if the lights had been short-circuited," interrupted
+Josephson, "Mr. Minturn would have escaped injury unless he had touched
+the taps of the bath. Oh, no, sir, accidents in the medical use of
+electricity are rare. They don't happen here in my establishment," he
+maintained stoutly. "The trouble was that the coroner, without any
+knowledge of the physiological effects of electricity on the body,
+simply jumped at once to the conclusion that it was the electric bath
+that did it."
+
+"Then it was for medical treatment that Mr. Minturn was taking the
+bath?" asked Kennedy, quickly taking up the point.
+
+"Yes, of course," answered the masseur, eager to explain. "You are
+acquainted with the latest treatment for lead poisoning by means of the
+electric bath?"
+
+Kennedy nodded. "I know that Sir Thomas Oliver, the English authority
+who has written much on dangerous trades, has tried it with marked
+success."
+
+"Well, sir, that was why Mr. Minturn was here. He came here introduced
+by a Dr. Gunther of Stratfield."
+
+"Indeed?" remarked Kennedy colorlessly, though I could see that it
+interested him, for evidently Minturn had said nothing of being himself
+a sufferer from the poison. "May I see the bath?"
+
+"Surely," said Josephson, leading the way upstairs.
+
+It was an oaken tub with metal rods on the two long sides, from which
+depended prismatic carbon rods. Kennedy examined it closely.
+
+"This is what we call a hydro-electric bath," Josephson explained.
+"Those rods on the sides are the electrodes. You see there are no metal
+parts in the tub itself. The rods are attached by wiring to a wall
+switch out here."
+
+He pointed to the next room. Kennedy examined the switch with care.
+
+"From it," went on Josephson, "wires lead to an accumulator battery of
+perhaps thirty volts. It uses very little current. Dr. Gunther tested
+it and found it all right."
+
+Craig leaned over the bath, and from the carbon electrodes scraped off
+a white powder in minute crystals.
+
+"Ordinarily," Josephson pursued, "lead is eliminated by the skin and
+kidneys. But now, as you know, it is being helped along by
+electrolysis. I talked to Dr. Gunther about it. It is his opinion that
+it is probably eliminated as a chloride from the tissues of the body to
+the electrodes in the bath in which the patient is wholly or partly
+immersed. On the positive electrodes we get the peroxide. On the
+negative there is a spongy metallic form of lead. But it is only a
+small amount."
+
+"The body has been removed?" asked Craig.
+
+"Not yet," the masseur replied. "The coroner has ordered it kept here
+under guard until he makes up his mind what disposition to have made of
+it."
+
+We were next ushered into a little room on the same floor, at the door
+of which was posted an official from the coroner.
+
+"First of all," remarked Craig, as he drew back the sheet and began, a
+minute examination of the earthly remains of the great lawyer, "there
+are to be considered the safeguards of the human body against the
+passage through it of a fatal electric current--the high electric
+resistance of the body itself. It is particularly high when the current
+must pass through joints such as wrists, knees, elbows, and quite high
+when the bones of the head are concerned. Still, there might have been
+an incautious application of the current to the head, especially when
+the subject is a person of advanced age or latent cerebral disease,
+though I don't know that that fits Mr. Minturn. That's strange," he
+muttered, looking up, puzzled. "I can find no mark of a burn on the
+body--absolutely no mark of anything."
+
+"That's what I say," put in Josephson, much pleased by what Kennedy
+said, for he had been waiting anxiously to see what Craig discovered on
+his own examination. "It's impossible."
+
+"It's all the more remarkable," went on Craig, half to himself and
+ignoring Josephson, "because burns due to electric currents are totally
+unlike those produced in other ways. They occur at the point of
+contact, usually about the arms and hands, or the head. Electricity is
+much to be feared when it involves the cranial cavity." He completed
+his examination of the head which once had carried secrets which
+themselves must have been incandescent.
+
+"Then, too, such burns are most often something more than superficial,
+for considerable heat is developed which leads to massive destruction
+and carbonization of the tissues to a considerable depth. I have seen
+actual losses of substance--a lump of killed flesh surrounded by
+healthy tissues. Besides, such burns show an unexpected indolence when
+compared to the violent pains of ordinary burns. Perhaps that is due to
+the destruction of the nerve endings. How did Minturn die? Was he
+alone? Was he dead when he was discovered?"
+
+"He was alone," replied Josephson, slowly endeavoring to tell it
+exactly as he had seen it, "but that's the strange part of it. He
+seemed to be suffering from a convulsion. I think he complained at
+first of a feeling of tightness of his throat and a twitching of the
+muscles of his hands and feet. Anyhow, he called for help. I was up
+here and we rushed in. Dr. Gunther had just brought him and then had
+gone away, after introducing him, and showing him the bath."
+
+Josephson proceeded slowly, evidently having been warned that anything
+he said might be used against him. "We carried him, when he was this
+way, into this very room. But it was only for a short time. Then came a
+violent convulsion. It seemed to extend rapidly all over his body. His
+legs were rigid, his feet bent, his head back. Why, he was resting only
+on his heels and the back of his head. You see, Mr. Kennedy, that
+simply could not be the electric shock."
+
+"Hardly," commented Kennedy, looking again at the body. "It looks more
+like a tetanus convulsion. Yet there does not seem to be any trace of a
+recent wound that might have caused lockjaw. How did he look?"
+
+"Oh, his face finally became livid," replied Josephson. "He had a
+ghastly, grinning expression, his eyes were wide, there was foam on his
+mouth, and his breathing was difficult."
+
+"Not like tetanus, either," revised Craig. "There the convulsion
+usually begins with the face and progresses to the other muscles. Here
+it seems to have gone the other way."
+
+"That lasted a minute or so," resumed the masseur. "Then he sank
+back--perfectly limp. I thought he was dead. But he was not. A cold
+sweat broke out all over him and he was as if in a deep sleep."
+
+"What did you do?" prompted Kennedy.
+
+"I didn't know what to do. I called an ambulance. But the moment the
+door opened, his body seemed to stiffen again. He had one other
+convulsion--and when he grew limp he was dead."
+
+
+
+
+CHAPTER XXIX
+
+THE LEAD POISONER
+
+
+It was a gruesome recital and I was glad to leave the baths finally
+with Kennedy. Josephson was quite evidently relieved at the attitude
+Craig had taken toward the coroner's conclusion that Minturn had been
+shocked to death. As far as I could see, however, it added to rather
+than cleared up the mystery.
+
+Craig went directly uptown to his laboratory, in contrast with our
+journey down, in abstracted silence, which was his manner when he was
+trying to reason out some particularly knotty problem.
+
+As Kennedy placed the white crystals which he had scraped off the
+electrodes of the tub on a piece of dark paper in the laboratory, he
+wet the tip of his finger and touched just the minutest grain to his
+tongue.
+
+The look on his face told me that something unexpected had happened. He
+held a similar minute speck of the powder out to me.
+
+It was an intensely bitter taste and very persistent, for even after we
+had rinsed out our mouths it seemed to remain, clinging persistently to
+the tongue.
+
+He placed some of the grains in some pure water. They dissolved only
+slightly, if at all. But in a tube in which he mixed a little ether and
+chloroform they dissolved fairly readily.
+
+Next, without a word, he poured just a drop of strong sulphuric acid on
+the crystals. There was not a change in them.
+
+Quickly he reached up into the rack and took down a bottle labeled
+"Potassium Bichromate."
+
+"Let us see what an oxidizing agent will do," he remarked.
+
+As he gently added the bichromate, there came a most marvelous,
+kaleidoscopic change. From being almost colorless, the crystals turned
+instantly to a deep blue, then rapidly to purple, lilac, red, and then
+the red slowly faded away and they became colorless again.
+
+"What is it?" I asked, fascinated. "Lead?"
+
+"N-no," he replied, the lines of his forehead deepening. "No. This is
+sulphate of strychnine."
+
+"Sulphate of strychnine?" I repeated in astonishment.
+
+"Yes," he reiterated slowly. "I might have suspected that from the
+convulsions, particularly when Josephson said that the noise and
+excitement of the arrival of the ambulance brought on the fatal
+paroxysm. That is symptomatic. But I didn't fully realize it until I
+got up here and tasted the stuff. Then I suspected, for that taste is
+characteristic. Even one part diluted seventy thousand times gives that
+decided bitter taste."
+
+"That's all very well," I remarked, recalling the intense bitterness
+yet on my tongue. "But how do you suppose it was possible for anyone to
+administer it? It seems to me that he would have said something, if he
+had swallowed even the minutest part of it. He must have known it. Yet
+apparently he didn't. At least he said nothing about it--or else
+Josephson is concealing something."
+
+"Did he swallow it--necessarily?" queried Kennedy, in a tone calculated
+to show me that the chemical world, at least, was full of a number of
+things, and there was much to learn.
+
+"Well, I suppose if it had been given hypodermically, it would have a
+more violent effect," I persisted, trying to figure out a way that the
+poison might have been given.
+
+"Even more unlikely," objected Craig, with a delight at discovering a
+new mystery that to me seemed almost fiendish. "No, he would certainly
+have felt a needle, have cried out and said something about it, if
+anyone had tried that. This poisoned needle business isn't as easy as
+some people seem to think nowadays."
+
+"Then he might have absorbed it from the water," I insisted, recalling
+a recent case of Kennedy's and adding, "by osmosis."
+
+"You saw how difficult it was to dissolve in water," Craig rejected
+quietly.
+
+"Well, then," I concluded in desperation. "How could it have been
+introduced?"
+
+"I have a theory," was all he would say, reaching for the railway
+guide, "but it will take me up to Stratfield to prove it."
+
+His plan gave us a little respite and we paused long enough to lunch,
+for which breathing space I was duly thankful. The forenoon saw us on
+the train, Kennedy carrying a large and cumbersome package which he
+brought down with him from the laboratory and which we took turns in
+carrying, though he gave no hint of its contents.
+
+We arrived in Stratfield, a very pretty little mill town, in the middle
+of the afternoon, and with very little trouble were directed to the
+Pearcy house, after Kennedy had checked the parcel with the station
+agent.
+
+Mrs. Pearcy, to whom we introduced ourselves as reporters of the Star,
+was a tall blonde. I could not help thinking that she made a
+particularly dashing widow. With her at the time was Isabel Pearcy, a
+slender girl whose sensitive lips and large, earnest eyes indicated a
+fine, high-strung nature.
+
+Even before we had introduced ourselves, I could not help thinking that
+there was a sort of hostility between the women. Certainly it was
+evident that there was as much difference in temperament as between the
+butterfly and the bee.
+
+"No," replied the elder woman quickly to a request from Kennedy for an
+interview, "there is nothing that I care to say to the newspapers. They
+have said too much already about this--unfortunate affair."
+
+Whether it was imagination or not, I fancied that there was an air of
+reserve about both women. It struck me as a most peculiar household.
+What was it? Was each suspicious of the other? Was each concealing
+something?
+
+I managed to steal a glance at Kennedy's face to see whether there was
+anything to confirm my own impression. He was watching Mrs. Pearcy
+closely as she spoke. In fact his next few questions, inconsequential
+as they were, seemed addressed to her solely for the purpose of getting
+her to speak.
+
+I followed his eyes and found that he was watching her mouth, in
+reality. As she answered I noted her beautiful white teeth. Kennedy
+himself had trained me to notice small things, and at the time, though
+I thought it was trivial, I recall noticing on her gums, where they
+joined the teeth, a peculiar bluish-black line.
+
+Kennedy had been careful to address only Mrs. Pearcy at first, and as
+he continued questioning her, she seemed to realize that he was trying
+to lead her along.
+
+"I must positively refuse to talk any more," she repeated finally,
+rising. "I am not to be tricked into saying anything."
+
+She had left the room, evidently expecting that Isabel would follow.
+She did not. In fact I felt that Miss Pearcy was visibly relieved by
+the departure of her stepmother. She seemed anxious to ask us something
+and now took the first opportunity.
+
+"Tell me," she said eagerly, "how did Mr. Minturn die? What do they
+really think of it in New York?"
+
+"They think it is poisoning," replied Craig, noting the look on her
+face.
+
+She betrayed nothing, as far as I could see, except a natural
+neighborly interest. "Poisoning?" she repeated. "By what?"
+
+"Lead poisoning," he replied evasively.
+
+She said nothing. It was evident that, slip of a girl though she was,
+she was quite the match of anyone who attempted leading questions.
+Kennedy changed his method.
+
+"You will pardon me," he said apologetically, "for recalling what must
+be distressing. But we newspapermen often have to do things and ask
+questions that are distasteful. I believe it is rumored that your
+father suffered from lead poisoning?"
+
+"Oh, I don't know what it was--none of us do," she cried, almost
+pathetically. "I had been living at the settlement until lately. When
+father grew worse, I came home. He had such strange
+visions--hallucinations, I suppose you would call them. In the daytime
+he would be so very morose and melancholy. Then, too, there were
+terrible pains in his stomach, and his eyesight began to fail. Yes, I
+believe that Dr. Gunther did say it was lead poisoning. But--they have
+said so many things--so many things," she repeated, plainly distressed
+at the subject of her recent bereavement.
+
+"Your brother is not at home?" asked Kennedy, quickly changing the
+subject.
+
+"No," she answered, then with a flash as though lifting the veil of a
+confidence, added: "You know, neither Warner nor I have lived here much
+this year. He has been in New York most of the time and I have been at
+the settlement, as I already told you."
+
+She hesitated, as if wondering whether she should say more, then added
+quickly: "It has been repeated often enough; there is no reason why I
+shouldn't say it to you. Neither of us exactly approved of father's
+marriage."
+
+She checked herself and glanced about, somewhat with the air of one who
+has suddenly considered the possibility of being overheard.
+
+"May I have a glass of water?" asked Kennedy suddenly.
+
+"Why, certainly," she answered, going to the door, apparently eager for
+an excuse to find out whether there was some one on the other side of
+it.
+
+There was not, nor any indication that there had been.
+
+"Evidently she does not have any suspicions of THAT," remarked Kennedy
+in an undertone, half to himself.
+
+I had no chance to question him, for she returned almost immediately.
+Instead of drinking the water, however, he held it carefully up to the
+light. It was slightly turbid.
+
+"You drink the water from the tap?" he asked, as he poured some of it
+into a sterilized vial which he drew quickly from his vest pocket.
+
+"Certainly," she replied, for the moment nonplussed at his strange
+actions. "Everybody drinks the town water in Stratfield."
+
+A few more questions, none of which were of importance, and Kennedy and
+I excused ourselves.
+
+At the gate, instead of turning toward the town, however, Kennedy went
+on and entered the grounds of the Minturn house next door. The lawyer,
+I had understood, was a widower and, though he lived in Stratfield only
+part of the time, still maintained his house there.
+
+We rang the bell and a middle-aged housekeeper answered.
+
+"I am from the water company," he began politely. "We are testing the
+water, perhaps will supply consumers with filters. Can you let me have
+a sample?"
+
+She did not demur, but invited us in. As she drew the water, Craig
+watched her hands closely. She seemed to have difficulty in holding the
+glass, and as she handed it to him, I noticed a peculiar hanging down
+of the wrist. Kennedy poured the sample into a second vial, and I
+noticed that it was turbid, too. With no mention of the tragedy to her
+employer, he excused himself, and we walked slowly back to the road.
+
+Between the two houses Kennedy paused, and for several moments appeared
+to be studying them.
+
+We walked slowly back along the road to the town. As we passed the
+local drug store, Kennedy turned and sauntered in.
+
+He found it easy enough to get into conversation with the druggist,
+after making a small purchase, and in the course of a few minutes we
+found ourselves gossiping behind the partition that shut off the arcana
+of the prescription counter from the rest of the store.
+
+Gradually Kennedy led the conversation around to the point which he
+wanted, and asked, "I wish you'd let me fix up a little sulphureted
+hydrogen."
+
+"Go ahead," granted the druggist good-naturedly. "I guess you can do
+it. You know as much about drugs as I do. I can stand the smell, if you
+can."
+
+Kennedy smiled and set to work.
+
+Slowly he passed the gas through the samples of water he had taken from
+the two houses. As he did so the gas, bubbling through, made a blackish
+precipitate.
+
+"What is it?" asked the druggist curiously.
+
+"Lead sulphide," replied Kennedy, stroking his chin. "This is an
+extremely delicate test. Why, one can get a distinct brownish tinge if
+lead is present in even incredibly minute quantities."
+
+He continued to work over the vials ranged on the table before him.
+
+"The water contains, I should say, from ten to fifteen hundredths of a
+grain of lead to the gallon," he remarked finally.
+
+"Where did it come from?" asked the druggist, unable longer to restrain
+his curiosity.
+
+"I got it up at Pearcy's," Kennedy replied frankly, turning to observe
+whether the druggist might betray any knowledge of it.
+
+"That's strange," he replied in genuine surprise. "Our water in
+Stratfield is supplied by a company to a large area, and it has always
+seemed to me to be of great organic purity."
+
+"But the pipes are of lead, are they not?" asked Kennedy.
+
+"Y-yes," answered the druggist, "I think in most places the service
+pipes are of lead. But," he added earnestly as he saw the implication
+of his admission, "water has never to my knowledge been found to attack
+the pipes so as to affect its quality injuriously."
+
+He turned his own faucet and drew a glassful. "It is normally quite
+clear," he added, holding the glass up.
+
+It was in fact perfectly clear, and when he passed some of the gas
+through it nothing happened at all.
+
+Just then a man lounged into the store.
+
+"Hello, Doctor," greeted the druggist. "Here are a couple of fellows
+that have been investigating the water up at Pearcy's. They've found
+lead in it. That ought to interest you. This is Dr. Gunther," he
+introduced, turning to us.
+
+It was an unexpected encounter, one I imagine that Kennedy might have
+preferred to take place under other circumstances. But he was equal to
+the occasion.
+
+"We've been sent up here to look into the case for the New York Star,"
+Kennedy said quickly. "I intended to come around to see you, but you
+have saved me the trouble."
+
+Dr. Gunther looked from one of us to the other. "Seems to me the New
+York papers ought to have enough to do without sending men all over the
+country making news," he grunted.
+
+"Well," drawled Kennedy quietly, "there seems to be a most remarkable
+situation up there at Pearcy's and Minturn's, too. As nearly as I can
+make out several people there are suffering from unmistakable signs of
+lead poisoning. There are the pains in the stomach, the colic, and then
+on the gums is that characteristic line of plumbic sulphide, the
+distinctive mark produced by lead. There is the wrist-drop, the
+eyesight affected, the partial paralysis, the hallucinations and a
+condition in old Pearcy's case almost bordering on insanity--to
+enumerate the symptoms that seem to be present in varying degrees in
+various persons in the two houses."
+
+Gunther looked at Kennedy, as if in doubt just how to take him.
+
+"That's what the coroner says, too--lead poisoning," put in the
+druggist, himself as keen as anyone else for a piece of local news, and
+evidently not averse to stimulating talk from Dr. Gunther, who had been
+Pearcy's physician.
+
+"That all seems to be true enough," replied Gunther at length
+guardedly. "I recognized that some time ago."
+
+"Why do you think it affects each so differently?" asked the druggist.
+
+Dr. Gunther settled himself easily back in a chair to speak as one
+having authority. "Well," he began slowly, "Miss Pearcy, of course,
+hasn't been living there much until lately. As for the others, perhaps
+this gentleman here from the Star knows that lead, once absorbed, may
+remain latent in the system and then make itself felt. It is like
+arsenic, an accumulative poison, slowly collecting in the body until
+the limit is reached, or until the body, becoming weakened from some
+other cause, gives way to it."
+
+He shifted his position slowly, and went on, as if defending the course
+of action he had taken in the case.
+
+"Then, too, you know, there is an individual as well as family and sex
+susceptibility to lead. Women are especially liable to lead poisoning,
+but then perhaps in this case Mrs. Pearcy comes of a family that is
+very resistant. There are many factors. Personally, I don't think
+Pearcy himself was resistant. Perhaps Minturn was not, either. At any
+rate, after Pearcy's death, it was I who advised Minturn to take the
+electrolysis cure in New York. I took him down there," added Gunther.
+"Confound it, I wish I had stayed with him. But I always found
+Josephson perfectly reliable in hydrotherapy with other patients I sent
+to him, and I understood that he had been very successful with cases
+sent to him by many physicians in the city." He paused and I waited
+anxiously to see whether Kennedy would make some reference to the
+discovery of the strychnine salts.
+
+"Have you any idea how the lead poisoning could have been caused?"
+asked Kennedy instead.
+
+Dr. Gunther shook his head. "It is a puzzle to me," he answered. "I am
+sure of only one thing. It could not be from working in lead, for it is
+needless to say that none of them worked."
+
+"Food?" Craig suggested.
+
+The doctor considered. "I had thought of that. I know that many cases
+of lead poisoning have been traced to the presence of the stuff in
+ordinary foods, drugs and drinks. I have examined the foods, especially
+the bread. They don't use canned goods. I even went so far as to
+examine the kitchen ware to see if there could be anything wrong with
+the glazing. They don't drink wines and beers, into which now and then
+the stuff seems to get."
+
+"You seem to have a good grasp of the subject," flattered Kennedy, as
+we rose to go. "I can hardly blame you for neglecting the water, since
+everyone here seems to be so sure of the purity of the supply."
+
+Gunther said nothing. I was not surprised, for, at the very least, no
+one likes to have an outsider come in and put his finger directly on
+the raw spot. What more there might be to it, I could only conjecture.
+
+We left the druggist's and Kennedy, glancing at his watch, remarked:
+"If you will go down to the station, Walter, and get that package we
+left there, I shall be much obliged to you. I want to make just one
+more stop, at the office of the water company, and I think I shall just
+about have time for it. There's a pretty good restaurant across the
+street. Meet me there, and by that time I shall know whether to carry
+out a little plan I have outlined or not."
+
+
+
+
+CHAPTER XXX
+
+THE ELECTROLYTIC MURDER
+
+
+We dined leisurely, which seemed strange to me, for it was not
+Kennedy's custom to let moments fly uselessly when he was on a case.
+However, I soon found out why it was. He was waiting for darkness.
+
+As soon as the lights began to glow in the little stores on the main
+street, we sallied forth, taking the direction of the Pearcy and
+Minturn houses.
+
+On the way he dropped into the hardware store and purchased a light
+spade and one of the small pocket electric flashlights, about which he
+wrapped a piece of cardboard in such a way as to make a most effective
+dark lantern.
+
+We trudged along in silence, occasionally changing from carrying the
+heavy package to the light spade.
+
+Both the Pearcy and Minturn houses were in nearly total darkness when
+we arrived. They set well back from the road and were plentifully
+shielded by shrubbery. Then, too, at night it was not a much frequented
+neighborhood. We could easily hear the footsteps of anyone approaching
+on the walk, and an occasional automobile gliding past did not worry us
+in the least.
+
+"I have calculated carefully from an examination of the water company's
+map," said Craig, "just where the water pipe of the two houses branches
+off from the main in the road."
+
+After a measurement or two from some landmark, we set to work a few
+feet inside, under cover of the bushes and the shadows, like two grave
+diggers.
+
+Kennedy had been wielding the spade vigorously for a few minutes when
+it touched something metallic. There, just beneath the frost line, we
+came upon the service pipe.
+
+He widened the hole, and carefully scraped off the damp earth that
+adhered to the pipe. Next he found a valve where he shut off the water
+and cut out a small piece of the pipe.
+
+"I hope they don't suspect anything like this in the houses with their
+water cut off," he remarked as he carefully split the piece open
+lengthwise and examined it under the light.
+
+On the interior of the pipe could be seen patchy lumps of white which
+projected about an eighth of an inch above the internal surface. As the
+pipe dried in the warm night air, they could easily be brushed off as a
+white powder.
+
+"What is it--strychnine?" I asked.
+
+"No," he replied, regarding it thoughtfully with some satisfaction.
+"That is lead carbonate. There can be no doubt that the turbidity of
+the water was due to this powder in suspension. A little dissolves in
+the water, while the scales and incrustations in fine particles are
+carried along in the current. As a matter of fact the amount necessary
+to make the water poisonous need not be large."
+
+He applied a little instrument to the cut ends of the pipe. As I bent
+over, I could see the needle on its dial deflected just a bit.
+
+"My voltmeter," he said, reading it, "shows that there is a current of
+about 1.8 volts passing through this pipe all the time."
+
+"Electrolysis of water pipes!" I exclaimed, thinking of statements I
+had heard by engineers. "That's what they mean by stray or vagabond
+currents, isn't it?"
+
+He had seized the lantern and was eagerly following up and down the
+line of the water pipe. At last he stopped, with a low exclamation, at
+a point where an electric light wire supplying the Minturn cottage
+crossed overhead. Fastened inconspicuously to the trunk of a tree which
+served as a support for the wire was another wire which led down from
+it and was buried in the ground.
+
+Craig turned up the soft earth as fast as he could, until he reached
+the pipe at this point. There was the buried wire wound several times
+around it.
+
+As quickly and as neatly as he could he inserted a connection between
+the severed ends of the pipe to restore the flow of water to the
+houses, turned on the water and covered up the holes he had dug. Then
+he unwrapped the package which we had tugged about all day, and in a
+narrow path between the bushes which led to the point where the wire
+had tapped the electric light feed he placed in a shallow hole in the
+ground a peculiar apparatus.
+
+As nearly as I could make it out, it consisted of two flat platforms
+between which, covered over and projected, was a slip of paper which
+moved forward, actuated by clockwork, and pressed on by a sort of
+stylus. Then he covered it over lightly with dirt so that, unless
+anyone had been looking for it, it would never be noticed.
+
+It was late when we reached the city again, but Kennedy had one more
+piece of work and that devolved on me. All the way down on the train he
+had been writing and rewriting something.
+
+"Walter," he said, as the train pulled into the station, "I want that
+published in to-morrow's papers."
+
+I looked over what he had written. It was one of the most sensational
+stories I have ever fathered, beginning, "Latest of the victims of the
+unknown poisoner of whole families in Stratfield, Connecticut, is Miss
+Isabel Pearcy, whose father, Randall Pearcy, died last week."
+
+I knew that it was a "plant" of some kind, for so far he had discovered
+no evidence that Miss Pearcy had been affected. What his purpose was, I
+could not guess, but I got the story printed.
+
+The next morning early Kennedy was quietly at work in the laboratory.
+
+"What is this treatment of lead poisoning by electrolysis?" I asked,
+now that there had come a lull when I might get an intelligible answer.
+"How does it work?"
+
+"Brand new, Walter," replied Kennedy. "It has been discovered that ions
+will flow directly through the membranes."
+
+"Ions?" I repeated. "What are ions?"
+
+"Travelers," he answered, smiling, "so named by Faraday from the Greek
+verb, io, to go. They are little positive and negative charges of
+electricity of which molecules are composed. You know some believe now
+that matter is really composed of electrical energy. I think I can
+explain it best by a simile I use with my classes. It is as though you
+had a ballroom in which the dancers in couples represent the neutral
+molecules. There are a certain number of isolated ladies and
+gentlemen--dissociated ions--" "Who don't know these new dances?" I
+interrupted.
+
+"They all know this dance," he laughed. "But, to be serious in the
+simile, suppose at one end of the room there is a large mirror and at
+the other a buffet with cigars and champagne. What happens to the
+dissociated ions?"
+
+"Well, I suppose you want me to say that the ladies gather about the
+mirror and the men about the buffet."
+
+"Exactly. And some of the dancing partners separate and follow the
+crowd. Well, that room presents a picture of what happens in an
+electrolytic solution at the moment when the electric current is
+passing through it."
+
+"Thanks," I laughed. "That was quite adequate to my immature
+understanding."
+
+Kennedy continued at work, checking up and arranging his data until the
+middle of the afternoon, when he went up to Stratfield.
+
+Having nothing better to do, I wandered out about town in the hope of
+running across some one with whom to while away the hours until Kennedy
+returned. I found out that, since yesterday, Broadway had woven an
+entirely new background for the mystery. Now it was rumored that the
+lawyer Minturn himself had been on very intimate terms with Mrs.
+Pearcy. I did not pay much attention to the rumor, for I knew that
+Broadway is constitutionally unable to believe that anybody is straight.
+
+Kennedy had commissioned me to keep in touch with Josephson and I
+finally managed to get around to the Baths, to find them still closed.
+
+As I was talking with him, a very muddy and dusty car pulled up at the
+door and a young man whose face was marred by the red congested blood
+vessels that are in some a mark of dissipation burst in on us.
+
+"What--closed up yet--Joe?" he asked. "Haven't they taken Minturn's
+body away?"
+
+"Yes, it was sent up to Stratfield to-day," replied the masseur, "but
+the coroner seems to want to worry me all he can."
+
+"Too bad. I was up almost all last night, and to-day I have been out in
+my car--tired to death. Thought I might get some rest here. Where are
+you sending the boys--to the Longacre?"
+
+"Yes. They'll take good care of you till I open up again. Hope to see
+you back again, then, Mr. Pearcy," he added, as the young man turned
+and hurried out to his car again. "That was that young Pearcy, you
+know. Nice boy--but living the life too fast. What's Kennedy
+doing--anything?"
+
+I did not like the jaunty bravado of the masseur which now seemed to be
+returning, since nothing definite had taken shape. I determined that he
+should not pump me, as he evidently was trying to do. I had at least
+fulfilled Kennedy's commission and felt that the sooner I left
+Josephson the better for both of us.
+
+I was surprised at dinner to receive a wire from Craig saying that he
+was bringing down Dr. Gunther, Mrs. Pearcy and Isabel to New York and
+asking me to have Warner Pearcy and Josephson at the laboratory at nine
+o'clock.
+
+By strategy I managed to persuade Pearcy to come, and as for Josephson,
+he could not very well escape, though I saw that as long as nothing
+more had happened, he was more interested in "fixing" the police so
+that he could resume business than anything else.
+
+As we entered the laboratory that night, Kennedy, who had left his
+party at a downtown hotel to freshen up, met us each at the door.
+Instead of conducting us in front of his laboratory table, which was
+the natural way, he led us singly around through the narrow space back
+of it.
+
+I recall that as I followed him, I half imagined that the floor gave
+way just a bit, and there flashed over me, by a queer association of
+ideas, the recollection of having visited an amusement park not long
+before where merely stepping on an innocent-looking section of the
+flooring had resulted in a tremendous knocking and banging beneath,
+much to the delight of the lovers of slap-stick humor. This was serious
+business, however, and I quickly banished the frivolous thought from my
+mind.
+
+"The discovery of poison, and its identification," began Craig at last
+when we had all arrived and were seated about him, "often involves not
+only the use of chemistry but also a knowledge of the chemical effect
+of the poison on the body, and the gross as well as microscopic changes
+which it produces in various tissues and organs--changes, some due to
+mere contact, others to the actual chemicophysiological reaction
+between the poison and the body."
+
+His hand was resting on the poles of a large battery, as he proceeded:
+"Every day the medical detective plays a more and more important part
+in the detection of crime, and I might say that, except in the case of
+crime complicated by a lunacy plea, his work has earned the respect of
+the courts and of detectives, while in the case of insanity the
+discredit is the fault rather of the law itself. The ways in which the
+doctor can be of use in untangling the facts in many forms of crime
+have become so numerous that the profession of medical detective may
+almost be called a specialty."
+
+Kennedy repeated what he had already told me about electrolysis, then
+placed between the poles of the battery a large piece of raw beef.
+
+He covered the negative electrode with blotting paper and soaked it in
+a beaker near at hand.
+
+"This solution," he explained, "is composed of potassium iodide. In
+this other beaker I have a mixture of ordinary starch."
+
+He soaked the positive electrode in the starch and then jammed the two
+against the soft red meat. Then he applied the current.
+
+A few moments later he withdrew the positive electrode. Both it and the
+meat under it were blue!
+
+"What has happened?" he asked. "The iodine ions have actually passed
+through the beef to the positive pole and the paper on the electrode.
+Here we have starch iodide."
+
+It was a startling idea, this of the introduction of a substance by
+electrolysis.
+
+"I may say," he resumed, "that the medical view of electricity is
+changing, due in large measure to the genius of the Frenchman, Dr.
+Leduc. The body, we know, is composed largely of water, with salts of
+soda and potash. It is an excellent electrolyte. Yet most doctors
+regard the introduction of substances by the electric current as
+insignificant or nonexistent. But on the contrary the introduction of
+drugs by electrolysis is regular and far from being insignificant may
+very easily bring about death.
+
+"That action," he went on, looking from one of us to another, "may be
+therapeutic, as in the cure for lead poisoning by removing the lead, or
+it may be toxic--as in the case of actually introducing such a poison
+as strychnine into the body by the same forces that will remove the
+lead."
+
+He paused a moment, to enforce the point which had already been
+suggested. I glanced about hastily. If anyone in his little audience
+was guilty, no one betrayed it, for all were following him, fascinated.
+Yet in the wildly throbbing brain of some one of them the guilty
+knowledge must be seared indelibly. Would the mere accusation be enough
+to dissociate the truth from, that brain or would Kennedy have to
+resort to other means?
+
+"Some one," he went on, in a low, tense voice, leaning forward, "some
+one who knew this effect placed strychnine salts on one of the
+electrodes of the bath which Owen Minturn was to use."
+
+He did not pause. Evidently he was planning to let the force of his
+exposure be cumulative, until from its sheer momentum it carried
+everything before it.
+
+"Walter," he ordered quickly. "Lend me a hand."
+
+Together we moved the laboratory table as he directed.
+
+There, in the floor, concealed by the shadow, he had placed the same
+apparatus which I had seen him bury in the path between the Pearcy and
+Minturn estates at Stratfield.
+
+We scarcely breathed.
+
+"This," he explained rapidly, "is what is known as a kinograph--the
+invention of Professor HeleShaw of London. It enables me to identify a
+person by his or her walk. Each of you as you entered this room has
+passed over this apparatus and has left a different mark on the paper
+which registers."
+
+For a moment he stopped, as if gathering strength for the final assault.
+
+"Until late this afternoon I had this kinograph secreted at a certain
+place in Stratfield. Some one had tampered with the leaden water pipes
+and the electric light cable. Fearful that the lead poisoning brought
+on by electrolysis might not produce its result in the intended victim,
+that person took advantage of the new discoveries in electrolysis to
+complete that work by introducing the deadly strychnine during the very
+process of cure of the lead poisoning."
+
+He slapped down a copy of a newspaper. "In the news this morning I told
+just enough of what I had discovered and colored it in such a way that
+I was sure I would arouse apprehension. I did it because I wanted to
+make the criminal revisit the real scene of the crime. There was a
+double motive now--to remove the evidence and to check the spread of
+the poisoning."
+
+He reached over, tore off the paper with a quick, decisive motion, and
+laid it beside another strip, a little discolored by moisture, as
+though the damp earth had touched it.
+
+"That person, alarmed lest something in the cleverly laid plot, might
+be discovered, went to a certain spot to remove the traces of the
+diabolical work which were hidden there. My kinograph shows the
+footsteps, shows as plainly as if I had been present, the exact person
+who tried to obliterate the evidence."
+
+An ashen pallor seemed to spread over the face of Miss Pearcy, as
+Kennedy shot out the words.
+
+"That person," he emphasized, "had planned to put out of the way one
+who had brought disgrace on the Pearcy family. It was an act of private
+justice."
+
+Mrs. Pearcy could stand the strain no longer. She had broken down and
+was weeping incoherently. I strained my ears to catch what she was
+murmuring. It was Minturn's name, not Gunther's, that was on her lips.
+
+"But," cried Kennedy, raising an accusatory finger from the kinograph
+tracing and pointing it like the finger of Fate itself, "but the
+self-appointed avenger forgot that the leaden water pipe was common to
+the two houses. Old Mr. Pearcy, the wronged, died first. Isabel has
+guessed the family skeleton--has tried hard to shield you, but, Warner
+Pearcy, you are the murderer!"
+
+
+
+
+CHAPTER XXXI
+
+THE EUGENIC BRIDE
+
+
+Scandal, such as that which Kennedy unearthed in this Pearcy case, was
+never much to his liking, yet he seemed destined, about this period of
+his career, to have a good deal of it.
+
+We had scarcely finished with the indictment that followed the arrest
+of young Pearcy, when we were confronted by a situation which was as
+unique as it was intensely modern.
+
+"There's absolutely no insanity in Eugenia's family," I heard a young
+man remark to Kennedy, as my key turned in the lock of the laboratory
+door.
+
+For a moment I hesitated about breaking in on a confidential
+conference, then reflected that, as they had probably already heard me
+at the lock, I had better go in and excuse myself.
+
+As I swung the door open, I saw a young man pacing up and down the
+laboratory nervously, too preoccupied even to notice the slight noise I
+had made.
+
+He paused in his nervous walk and faced Kennedy, his back to me.
+
+"Kennedy," he said huskily, "I wouldn't care if there was insanity in
+her family--for, my God!--the tragedy of it all now--I love her!"
+
+He turned, following Kennedy's eyes in my direction, and I saw on his
+face the most haggard, haunting look of anxiety that I had ever seen on
+a young person.
+
+Instantly I recognized from the pictures I had seen in the newspapers
+young Quincy Atherton, the last of this famous line of the family, who
+had attracted a great deal of attention several months previously by
+what the newspapers had called his search through society for a
+"eugenics bride," to infuse new blood into the Atherton stock.
+
+"You need have no fear that Mr. Jameson will be like the other
+newspaper men," reassured Craig, as he introduced us, mindful of the
+prejudice which the unpleasant notoriety of Atherton's marriage had
+already engendered in his mind.
+
+I recalled that when I had first heard of Atherton's "eugenic
+marriage," I had instinctively felt a prejudice against the very idea
+of such cold, calculating, materialistic, scientific mating, as if one
+of the last fixed points were disappearing in the chaos of the social
+and sex upheaval.
+
+Now, I saw that one great fact of life must always remain. We might
+ride in hydroaeroplanes, delve into the very soul by psychanalysis,
+perhaps even run our machines by the internal forces of radium--even
+marry according to Galton or Mendel. But there would always be love,
+deep passionate love of the man for the woman, love which all the
+discoveries of science might perhaps direct a little less blindly, but
+the consuming flame of which not all the coldness of science could ever
+quench. No tampering with the roots of human nature could ever change
+the roots.
+
+I must say that I rather liked young Atherton. He had a frank, open
+face, the most prominent feature of which was his somewhat aristocratic
+nose. Otherwise he impressed one as being the victim of heredity in
+faults, if at all serious, against which he was struggling heroically.
+
+It was a most pathetic story which he told, a story of how his family
+had degenerated from the strong stock of his ancestors until he was the
+last of the line. He told of his education, how he had fallen, a rather
+wild youth bent in the footsteps of his father who had been a
+notoriously good clubfellow, under the influence of a college
+professor, Dr. Crafts, a classmate of his father's, of how the
+professor had carefully and persistently fostered in him an idea that
+had completely changed him.
+
+"Crafts always said it was a case of eugenics against euthenics,"
+remarked Atherton, "of birth against environment. He would tell me over
+and over that birth gave me the clay, and it wasn't such bad clay after
+all, but that environment would shape the vessel."
+
+Then Atherton launched into a description of how he had striven to find
+a girl who had the strong qualities his family germ plasm seemed to
+have lost, mainly, I gathered, resistance to a taint much like manic
+depressive insanity. And as he talked, it was borne in on me that,
+after all, contrary to my first prejudice, there was nothing very
+romantic indeed about disregarding the plain teachings of science on
+the subject of marriage and one's children.
+
+In his search for a bride, Dr. Crafts, who had founded a sort of
+Eugenics Bureau, had come to advise him. Others may have looked up
+their brides in Bradstreet's, or at least the Social Register. Atherton
+had gone higher, had been overjoyed to find that a girl he had met in
+the West, Eugenia Gilman, measured up to what his friend told him were
+the latest teachings of science. He had been overjoyed because, long
+before Crafts had told him, he had found out that he loved her deeply.
+
+"And now," he went on, half choking with emotion, "she is apparently
+suffering from just the same sort of depression as I myself might
+suffer from if the recessive trait became active."
+
+"What do you mean, for instance?" asked Craig.
+
+"Well, for one thing, she has the delusion that my relatives are
+persecuting her."
+
+"Persecuting her?" repeated Craig, stifling the remark that that was
+not in itself a new thing in this or any other family. "How?"
+
+"Oh, making her feel that, after all, it is Atherton family rather than
+Gilman health that counts--little remarks that when our baby is born,
+they hope it will resemble Quincy rather than Eugenia, and all that
+sort of thing, only worse and more cutting, until the thing has begun
+to prey on her mind."
+
+"I see," remarked Kennedy thoughtfully. "But don't you think this is a
+case for a--a doctor, rather than a detective?"
+
+Atherton glanced up quickly. "Kennedy," he answered slowly, "where
+millions of dollars are involved, no one can guess to what lengths the
+human mind will go--no one, except you."
+
+"Then you have suspicions of something worse?"
+
+"Y-yes--but nothing definite. Now, take this case. If I should die
+childless, after my wife, the Atherton estate would descend to my
+nearest relative, Burroughs Atherton, a cousin."
+
+"Unless you willed it to--"
+
+"I have already drawn a will," he interrupted, "and in case I survive
+Eugenia and die childless, the money goes to the founding of a larger
+Eugenics Bureau, to prevent in the future, as much as possible,
+tragedies such as this of which I find myself a part. If the case is
+reversed, Eugenia will get her third and the remainder will go to the
+Bureau or the Foundation, as I call the new venture. But," and here
+young Atherton leaned forward and fixed his large eyes keenly on us,
+"Burroughs might break the will. He might show that I was of unsound
+mind, or that Eugenia was, too."
+
+"Are there no other relatives?"
+
+"Burroughs is the nearest," he replied, then added frankly, "I have a
+second cousin, a young lady named Edith Atherton, with whom both
+Burroughs and I used to be very friendly."
+
+It was evident from the way he spoke that he had thought a great deal
+about Edith Atherton, and still thought well of her.
+
+"Your wife thinks it is Burroughs who is persecuting her?" asked
+Kennedy.
+
+Atherton shrugged his shoulders.
+
+"Does she get along badly with Edith? She knows her I presume?"
+
+"Of course. The fact is that since the death of her mother, Edith has
+been living with us. She is a splendid girl, and all alone in the world
+now, and I had hopes that in New York she might meet some one and marry
+well."
+
+Kennedy was looking squarely at Atherton, wondering whether he might
+ask a question without seeming impertinent. Atherton caught the look,
+read it, and answered quite frankly, "To tell the truth, I suppose I
+might have married Edith, before I met Eugenia, if Professor Crafts had
+not dissuaded me. But it wouldn't have been real love--nor wise. You
+know," he went on more frankly, now that the first hesitation was over
+and he realized that if he were to gain anything at all by Kennedy's
+services, there must be the utmost candor between them, "you know
+cousins may marry if the stocks are known to be strong. But if there is
+a defect, it is almost sure to be intensified. And so I--I gave up the
+idea--never had it, in fact, so strongly as to propose to her. And when
+I met Eugenia all the Athertons on the family tree couldn't have bucked
+up against the combination."
+
+He was deadly in earnest as he arose from the chair into which he had
+dropped after I came in.
+
+"Oh, it's terrible--this haunting fear, this obsession that I have had,
+that, in spite of all I have tried to do, some one, somehow, will
+defeat me. Then comes the situation, just at a time when Eugenia and I
+feel that we have won against Fate, and she in particular needs all the
+consideration and care in the world--and--and I am defeated."
+
+Atherton was again pacing the laboratory.
+
+"I have my car waiting outside," he pleaded. "I wish you would go with
+me to see Eugenia--now."
+
+It was impossible to resist him. Kennedy rose and I followed, not
+without a trace of misgiving.
+
+The Atherton mansion was one of the old houses of the city, a somber
+stone dwelling with a garden about it on a downtown square, on which
+business was already encroaching. We were admitted by a servant who
+seemed to walk over the polished floors with stealthy step as if there
+was something sacred about even the Atherton silence. As we waited in a
+high-ceilinged drawing-room with exquisite old tapestries on the walls,
+I could not help feeling myself the influence of wealth and birth that
+seemed to cry out from every object of art in the house.
+
+On the longer wall of the room, I saw a group of paintings. One, I
+noted especially, must have been Atherton's ancestor, the founder of
+the line. There was the same nose in Atherton, for instance, a striking
+instance of heredity. I studied the face carefully. There was every
+element of strength in it, and I thought instinctively that, whatever
+might have been the effects of in-breeding and bad alliances, there
+must still be some of that strength left in the present descendant of
+the house of Atherton. The more I thought about the house, the
+portrait, the whole case, the more unable was I to get out of my head a
+feeling that though I had not been in such a position before, I had at
+least read or heard something of which it vaguely reminded me.
+
+Eugenia Atherton was reclining listlessly in her room in a deep leather
+easy chair, when Atherton took us up at last. She did not rise to greet
+us, but I noted that she was attired in what Kennedy once called, as we
+strolled up the Avenue, "the expensive sloppiness of the present
+styles." In her case the looseness with which her clothes hung was
+exaggerated by the lack of energy with which she wore them.
+
+She had been a beautiful girl, I knew. In fact, one could see that she
+must have been. Now, however, she showed marks of change. Her eyes were
+large, and protruding, not with the fire of passion which is often
+associated with large eyes, but dully, set in a puffy face, a trifle
+florid. Her hands seemed, when she moved them, to shake with an
+involuntary tremor, and in spite of the fact that one almost could feel
+that her heart and lungs were speeding with energy, she had lost weight
+and no longer had the full, rounded figure of health. Her manner showed
+severe mental disturbance, indifference, depression, a distressing
+deterioration. All her attractive Western breeziness was gone. One felt
+the tragedy of it only too keenly.
+
+"I have asked Professor Kennedy, a specialist, to call, my dear," said
+Atherton gently, without mentioning what the specialty was.
+
+"Another one?" she queried languorously.
+
+There was a colorless indifference in the tone which was almost tragic.
+She said the words slowly and deliberately, as though even her mind
+worked that way.
+
+From the first, I saw that Kennedy had been observing Eugenia Atherton
+keenly. And in the role of specialist in nervous diseases he was
+enabled to do what otherwise would have been difficult to accomplish.
+
+Gradually, from observing her mental condition of indifference which
+made conversation extremely difficult as well as profitless, he began
+to consider her physical condition. I knew him well enough to gather
+from his manner alone as he went on that what had seemed at the start
+to be merely a curious case, because it concerned the Athertons, was
+looming up in his mind as unusual in itself, and was interesting him
+because it baffled him.
+
+Craig had just discovered that her pulse was abnormally high, and that
+consequently she had a high temperature, and was sweating profusely.
+
+"Would you mind turning your head, Mrs. Atherton?" he asked.
+
+She turned slowly, half way, her eyes fixed vacantly on the floor until
+we could see the once striking profile.
+
+"No, all the way around, if you please," added Kennedy.
+
+She offered no objection, not the slightest resistance. As she turned
+her head as far as she could, Kennedy quickly placed his forefinger and
+thumb gently on her throat, the once beautiful throat, now with skin
+harsh and rough. Softly he moved his fingers just a fraction of an inch
+over the so-called "Adam's apple" and around it for a little distance.
+
+"Thank you," he said. "Now around to the other side."
+
+He made no other remark as he repeated the process, but I fancied I
+could tell that he had had an instant suspicion of something the moment
+he touched her throat.
+
+He rose abstractedly, bowed, and we started to leave the room,
+uncertain whether she knew or cared. Quincy had fixed his eyes silently
+on Craig, as if imploring him to speak, but I knew how unlikely that
+was until he had confirmed his suspicion to the last slightest detail.
+
+We were passing through a dressing room in the suite when we met a tall
+young woman, whose face I instantly recognized, not because I had ever
+seen it before, but because she had the Atherton nose so prominently
+developed.
+
+"My cousin, Edith," introduced Quincy.
+
+We bowed and stood for a moment chatting. There seemed to be no reason
+why we should leave the suite, since Mrs. Atherton paid so little
+attention to us even when we had been in the same room. Yet a slight
+movement in her room told me that in spite of her lethargy she seemed
+to know that we were there and to recognize who had joined us.
+
+Edith Atherton was a noticeable woman, a woman of temperament, not
+beautiful exactly, but with a stateliness about her, an aloofness. The
+more I studied her face, with its thin sensitive lips and commanding,
+almost imperious eyes, the more there seemed to be something peculiar
+about her. She was dressed very simply in black, but it was the
+simplicity that costs. One thing was quite evident--her pride in the
+family of Atherton.
+
+And as we talked, it seemed to be that she, much more than Eugenia in
+her former blooming health, was a part of the somber house. There came
+over me again the impression I had received before that I had read or
+heard something like this case before.
+
+She did not linger long, but continued her stately way into the room
+where Eugenia sat. And at once it flashed over me what my impression,
+indefinable, half formed, was. I could not help thinking, as I saw her
+pass, of the lady Madeline in "The Fall of the House of Usher."
+
+
+
+
+CHAPTER XXXII
+
+THE GERM PLASM
+
+
+I regarded her with utter astonishment and yet found it impossible to
+account for such a feeling. I looked at Atherton, but on his face I
+could see nothing but a sort of questioning fear that only increased my
+illusion, as if he, too, had only a vague, haunting premonition of
+something terrible impending. Almost I began to wonder whether the
+Atherton house might not crumble under the fierceness of a sudden
+whirlwind, while the two women in this case, one representing the
+wasted past, the other the blasted future, dragged Atherton down, as
+the whole scene dissolved into some ghostly tarn. It was only for a
+moment, and then I saw that the more practical Kennedy had been
+examining some bottles on the lady's dresser before which we had paused.
+
+One was a plain bottle of pellets which might have been some
+homeopathic remedy.
+
+"Whatever it is that is the matter with Eugenia," remarked Atherton,
+"it seems to have baffled the doctors so far."
+
+Kennedy said nothing, but I saw that he had clumsily overturned the
+bottle and absently set it up again, as though his thoughts were far
+away. Yet with a cleverness that would have done credit to a professor
+of legerdemain he had managed to extract two or three of the pellets.
+
+"Yes," he said, as he moved slowly toward the staircase in the wide
+hall, "most baffling."
+
+Atherton was plainly disappointed. Evidently he had expected Kennedy to
+arrive at the truth and set matters right by some sudden piece of
+wizardry, and it was with difficulty that he refrained from saying so.
+
+"I should like to meet Burroughs Atherton," he remarked as we stood in
+the wide hall on the first floor of the big house. "Is he a frequent
+visitor?"
+
+"Not frequent," hastened Quincy Atherton, in a tone that showed some
+satisfaction in saying it. "However, by a lucky chance he has promised
+to call to-night--a mere courtesy, I believe, to Edith, since she has
+come to town on a visit."
+
+"Good!" exclaimed Kennedy. "Now, I leave it to you, Atherton, to make
+some plausible excuse for our meeting Burroughs here."
+
+"I can do that easily."
+
+"I shall be here early," pursued Kennedy as we left.
+
+Back again in the laboratory to which Atherton insisted on accompanying
+us in his car, Kennedy busied himself for a few minutes, crushing up
+one of the tablets and trying one or two reactions with some of the
+powder dissolved, while I looked on curiously.
+
+"Craig," I remarked contemplatively, after a while, "how about Atherton
+himself? Is he really free from the--er--stigmata, I suppose you call
+them, of insanity?"
+
+"You mean, may the whole trouble lie with him?" he asked, not looking
+up from his work.
+
+"Yes--and the effect on her be a sort of reflex, say, perhaps the
+effect of having sold herself for money and position. In other words,
+does she, did she, ever love him? We don't know that. Might it not prey
+on her mind, until with the kind help of his precious relatives even
+Nature herself could not stand the strain--especially in the delicate
+condition in which she now finds herself?"
+
+I must admit that I felt the utmost sympathy for the poor girl whom we
+had just seen such a pitiable wreck.
+
+Kennedy closed his eyes tightly until they wrinkled at the corners.
+
+"I think I have found out the immediate cause of her trouble," he said
+simply, ignoring my suggestion.
+
+"What is it?" I asked eagerly.
+
+"I can't imagine how they could have failed to guess it, except that
+they never would have suspected to look for anything resembling
+exophthalmic goiter in a person of her stamina," he answered,
+pronouncing the word slowly. "You have heard of the thyroid gland in
+the neck?"
+
+"Yes?" I queried, for it was a mere name to me.
+
+"It is a vascular organ lying under the chin with a sort of little
+isthmus joining the two parts on either side of the windpipe," he
+explained. "Well, when there is any deterioration of those glands
+through any cause, all sorts of complications may arise. The thyroid is
+one of the so-called ductless glands, like the adrenals above the
+kidneys, the pineal gland and the pituitary body. In normal activity
+they discharge into the blood substances which are carried to other
+organs and are now known to be absolutely essential.
+
+"The substances which they secrete are called 'hormones'--those
+chemical messengers, as it were, by which many of the processes of the
+body are regulated. In fact, no field of experimental physiology is
+richer in interest than this. It seems that few ordinary drugs approach
+in their effects on metabolism the hormones of the thyroid. In excess
+they produce such diseases as exophthalmic goiter, and goiter is
+concerned with the enlargement of the glands and surrounding tissues
+beyond anything like natural size. Then, too, a defect in the glands
+causes the disease known as myxedema in adults and cretinism in
+children. Most of all, the gland seems to tell on the germ plasm of the
+body, especially in women."
+
+I listened in amazement, hardly knowing what to think. Did his
+discovery portend something diabolical, or was it purely a defect in
+nature which Dr. Crafts of the Eugenics Bureau had overlooked?
+
+"One thing at a time, Walter," cautioned Kennedy, when I put the
+question to him, scarcely expecting an answer yet.
+
+That night in the old Atherton mansion, while we waited for Borroughs
+to arrive, Kennedy, whose fertile mind had contrived to kill at least
+two birds with one stone, busied himself by cutting in on the regular
+telephone line and placing an extension of his own in a closet in the
+library. To it he attached an ordinary telephone receiver fastened to
+an arrangement which was strange to me. As nearly as I can describe it,
+between the diaphragm of the regular receiver and a brownish cylinder,
+like that of a phonograph, and with a needle attached, was fitted an
+air chamber of small size, open to the outer air by a small hole to
+prevent compression.
+
+The work was completed expeditiously, but we had plenty of time to
+wait, for Borroughs Atherton evidently did not consider that an evening
+had fairly begun until nine o'clock.
+
+He arrived at last, however, rather tall, slight of figure,
+narrow-shouldered, designed for the latest models of imported fabrics.
+It was evident merely by shaking hands with Burroughs that he thought
+both the Athertons and the Burroughses just the right combination. He
+was one of those few men against whom I conceive an instinctive
+prejudice, and in this case I felt positive that, whatever faults the
+Atherton germ plasm might contain, he had combined others from the
+determiners of that of the other ancestors he boasted. I could not help
+feeling that Eugenia Atherton was in about as unpleasant an atmosphere
+of social miasma as could be imagined.
+
+Burroughs asked politely after Eugenia, but it was evident that the
+real deference was paid to Edith Atherton and that they got along very
+well together. Burroughs excused himself early, and we followed soon
+after.
+
+"I think I shall go around to this Eugenics Bureau of Dr. Crafts,"
+remarked Kennedy the next day, after a night's consideration of the
+case.
+
+The Bureau occupied a floor in a dwelling house uptown which had been
+remodeled into an office building. Huge cabinets were stacked up
+against the walls, and in them several women were engaged in filing
+blanks and card records. Another part of the office consisted of an
+extensive library on eugenic subjects.
+
+Dr. Crafts, in charge of the work, whom we found in a little office in
+front partitioned off by ground glass, was an old man with an alert,
+vigorous mind on whom the effects of plain living and high thinking
+showed plainly. He was looking over some new blanks with a young woman
+who seemed to be working with him, directing the force of clerks as
+well as the "field workers," who were gathering the vast mass of
+information which was being studied. As we introduced ourselves, he
+introduced Dr. Maude Schofield.
+
+"I have heard of your eugenic marriage contests," began Kennedy, "more
+especially of what you have done for Mr. Quincy Atherton."
+
+"Well--not exactly a contest in that case, at least," corrected Dr.
+Crafts with an indulgent smile for a layman.
+
+"No," put in Dr. Schofield, "the Eugenics Bureau isn't a human stock
+farm."
+
+"I see," commented Kennedy, who had no such idea, anyhow. He was always
+lenient with anyone who had what he often referred to as the "illusion
+of grandeur."
+
+"We advise people sometimes regarding the desirability or the
+undesirability of marriage," mollified Dr. Crafts. "This is a sort of
+clearing house for scientific race investigation and improvement."
+
+"At any rate," persisted Kennedy, "after investigation, I understand,
+you advised in favor of his marriage with Miss Gilman."
+
+"Yes, Eugenia Gilman seemed to measure well up to the requirements in
+such a match. Her branch of the Gilmans has always been of the
+vigorous, pioneering type, as well as intellectual. Her father was one
+of the foremost thinkers in the West; in fact had long held ideas on
+the betterment of the race. You see that in the choice of a name for
+his daughter--Eugenia."
+
+"Then there were no recessive traits in her family," asked Kennedy
+quickly, "of the same sort that you find in the Athertons?"
+
+"None that we could discover," answered Dr. Crafts positively.
+
+"No epilepsy, no insanity of any form?"
+
+"No. Of course, you understand that almost no one is what might be
+called eugenically perfect. Strictly speaking, perhaps not over two or
+three per cent. of the population even approximates that standard. But
+it seemed to me that in everything essential in this case, weakness
+latent in Atherton was mating strength in Eugenia and the same way on
+her part for an entirely different set of traits."
+
+"Still," considered Kennedy, "there might have been something latent in
+her family germ plasm back of the time through which you could trace
+it?"
+
+Dr. Crafts shrugged his shoulders. "There often is, I must admit,
+something we can't discover because it lies too far back in the past."
+
+"And likely to crop out after skipping generations," put in Maude
+Schofield.
+
+She evidently did not take the same liberal view in the practical
+application of the matter expressed by her chief. I set it down to the
+ardor of youth in a new cause, which often becomes the saner
+conservatism of maturity.
+
+"Of course, you found it much easier than usual to get at the true
+family history of the Athertons," pursued Kennedy. "It is an old family
+and has been prominent for generations."
+
+"Naturally," assented Dr. Crafts.
+
+"You know Burroughs Atherton on both lines of descent?" asked Kennedy,
+changing the subject abruptly.
+
+"Yes, fairly well," answered Crafts.
+
+"Now, for example," went on Craig, "how would you advise him to marry?"
+
+I saw at once that he was taking this subterfuge as a way of securing
+information which might otherwise have been withheld if asked for
+directly. Maude Schofield also saw it, I fancied, but this time said
+nothing. "They had a grandfather who was a manic depressive on the
+Atherton side," said Crafts slowly. "Now, no attempt has ever been made
+to breed that defect out of the family. In the case of Burroughs, it is
+perhaps a little worse, for the other side of his ancestry is not free
+from the taint of alcoholism."
+
+"And Edith Atherton?"
+
+"The same way. They both carry it. I won't go into the Mendelian law on
+the subject. We are clearing up much that is obscure. But as to
+Burroughs, he should marry, if at all, some one without that particular
+taint. I believe that in a few generations by proper mating most taints
+might be bred out of families."
+
+Maude Schofield evidently did not agree with Dr. Crafts on some point,
+and, noticing it, he seemed to be in the position both of explaining
+his contention to us and of defending it before his fair assistant.
+
+"It is my opinion, as far as I have gone with the data," he added,
+"that there is hope for many of those whose family history shows
+certain nervous taints. A sweeping prohibition of such marriages would
+be futile, perhaps injurious. It is necessary that the mating be
+carefully made, however, to prevent intensifying the taint. You see,
+though I am a eugenist I am not an extremist."
+
+He paused, then resumed argumentatively: "Then there are other
+questions, too, like that of genius with its close relation to manic
+depressive insanity. Also, there is decrease enough in the birth rate,
+without adding an excuse for it. No, that a young man like Atherton
+should take the subject seriously, instead of spending his time in wild
+dissipation, like his father, is certainly creditable, argues in itself
+that there still must exist some strength in his stock.
+
+"And, of course," he continued warmly, "when I say that weakness in a
+trait--not in all traits, by any means--should marry strength and that
+strength may marry weakness, I don't mean that all matches should be
+like that. If we are too strict we may prohibit practically all
+marriages. In Atherton's case, as in many another, I felt that I should
+interpret the rule as sanely as possible."
+
+"Strength should marry strength, and weakness should never marry,"
+persisted Maude Schofield. "Nothing short of that will satisfy the true
+eugenist."
+
+"Theoretically," objected Crafts. "But Atherton was going to marry,
+anyhow. The only thing for me to do was to lay down a rule which he
+might follow safely. Besides, any other rule meant sure disaster."
+
+"It was the only rule with half a chance of being followed and at any
+rate," drawled Kennedy, as the eugenists wrangled, "what difference
+does it make in this case? As nearly as I can make out it is Mrs.
+Atherton herself, not Atherton, who is ill."
+
+Maude Schofield had risen to return to supervising a clerk who needed
+help. She left us, still unconvinced.
+
+"That is a very clever girl," remarked Kennedy as she shut the door and
+he scanned Dr. Crafts' face dosely.
+
+"Very," assented the Doctor.
+
+"The Schofields come of good stock?" hazarded Kennedy.
+
+"Very," assented Dr. Crafts again.
+
+Evidently he did not care to talk about individual cases, and I felt
+that the rule was a safe one, to prevent Eugenics from becoming Gossip.
+Kennedy thanked him for his courtesy, and we left apparently on the
+best of terms both with Crafts and his assistant.
+
+
+
+
+CHAPTER XXXIII
+
+THE SEX CONTROL
+
+
+I did not see Kennedy again that day until late in the afternoon, when
+he came into the laboratory carrying a small package.
+
+"Theory is one thing, practice is another," he remarked, as he threw
+his hat and coat into a chair.
+
+"Which means--in this case?" I prompted.
+
+"Why, I have just seen Atherton. Of course I didn't repeat our
+conversation of this morning, and I'm glad I didn't. He almost makes me
+think you are right, Walter. He's obsessed by the fear of Burroughs.
+Why, he even told me that Burroughs had gone so far as to take a leaf
+out of his book, so to speak, get in touch with the Eugenics Bureau as
+if to follow his footsteps, but really to pump them about Atherton
+himself. Atherton says it's all Burroughs' plan to break his will and
+that the fellow has even gone so far as to cultivate the acquaintance
+of Maude Schofield, knowing that he will get no sympathy from Crafts."
+
+"First it was Edith Atherton, now it is Maude Schofield that he hitches
+up with Burroughs," I commented. "Seems to me that I have heard that
+one of the first signs of insanity is belief that everyone about the
+victim is conspiring against him. I haven't any love for any of
+them--but I must be fair."
+
+"Well," said Kennedy, unwrapping the package, "there IS this much to
+it. Atherton says Burroughs and Maude Schofield have been seen together
+more than once--and not at intellectual gatherings either. Burroughs is
+a fascinating fellow to a woman, if he wants to be, and the Schofields
+are at least the social equals of the Burroughs. Besides," he added,
+"in spite of eugenics, feminism, and all the rest--sex, like murder,
+will out. There's no use having any false ideas about THAT. Atherton
+may see red--but, then, he was quite excited."
+
+"Over what?" I asked, perplexed more than ever at the turn of events.
+
+"He called me up in the first place. 'Can't you do something?' he
+implored. 'Eugenia is getting worse all the time.' She is, too. I saw
+her for a moment, and she was even more vacant than yesterday."
+
+The thought of the poor girl in the big house somehow brought over me
+again my first impression of Poe's story.
+
+Kennedy had unwrapped the package which proved to be the instrument he
+had left in the closet at Atherton's. It was, as I had observed, like
+an ordinary wax cylinder phonograph record.
+
+"You see," explained Kennedy, "it is nothing more than a successful
+application at last of, say, one of those phonographs you have seen in
+offices for taking dictation, placed so that the feebler vibrations of
+the telephone affect it. Let us see what we have here."
+
+He had attached the cylinder to an ordinary phonograph, and after a
+number of routine calls had been run off, he came to this, in voices
+which we could only guess at but not recognize, for no names were used.
+
+"How is she to-day?"
+
+"Not much changed--perhaps not so well."
+
+"It's all right, though. That is natural. It is working well. I think
+you might increase the dose, one tablet."
+
+"You're sure it is all right?" (with anxiety).
+
+"Oh, positively--it has been done in Europe."
+
+"I hope so. It must be a boy--and an ATHERTON?"
+
+"Never fear."
+
+That was all. Who was it? The voices were unfamiliar to me, especially
+when repeated mechanically. Besides they may have been disguised. At
+any rate we had learned something. Some one was trying to control the
+sex of the expected Atherton heir. But that was about all. Who it was,
+we knew no better, apparently, than before.
+
+Kennedy did not seem to care much, however. Quickly he got Quincy
+Atherton on the wire and arranged for Atherton to have Dr. Crafts meet
+us at the house at eight o'clock that night, with Maude Schofield. Then
+he asked that Burroughs Atherton be there, and of course, Edith and
+Eugenia.
+
+We arrived almost as the clock was striking, Kennedy carrying the
+phonograph record and another blank record, and a boy tugging along the
+machine itself. Dr. Crafts was the next to appear, expressing surprise
+at meeting us, and I thought a bit annoyed, for he mentioned that it
+had been with reluctance that he had had to give up some work he had
+planned for the evening. Maude Schofield, who came with him, looked
+bored. Knowing that she disapproved of the match with Eugenia, I was
+not surprised. Burroughs arrived, not as late as I had expected, but
+almost insultingly supercilious at finding so many strangers at what
+Atherton had told him was to be a family conference, in order to get
+him to come. Last of all Edith Atherton descended the staircase, the
+personification of dignity, bowing to each with a studied graciousness,
+as if distributing largess, but greeting Burroughs with an air that
+plainly showed how much thicker was blood than water. Eugenia remained
+upstairs, lethargic, almost cataleptic, as Atherton told us when we
+arrived.
+
+"I trust you are not going to keep us long, Quincy," yawned Burroughs,
+looking ostentatiously at his watch.
+
+"Only long enough for Professor Kennedy to say a few words about
+Eugenia," replied Atherton nervously, bowing to Kennedy.
+
+Kennedy cleared his throat slowly.
+
+"I don't know that I have much to say," began Kennedy, still seated. "I
+suppose Mr. Atherton has told you I have been much interested in the
+peculiar state of health of Mrs. Atherton?"
+
+No one spoke, and he went on easily: "There is something I might say,
+however, about the--er--what I call the chemistry of insanity. Among
+the present wonders of science, as you doubtless know, none stirs the
+imagination so powerfully as the doctrine that at least some forms of
+insanity are the result of chemical changes in the blood. For instance,
+ill temper, intoxication, many things are due to chemical changes in
+the blood acting on the brain.
+
+"Go further back. Take typhoid fever with its delirium, influenza with
+its suicide mania. All due to toxins--poisons.
+Chemistry--chemistry--all of them chemistry."
+
+Craig had begun carefully so as to win their attention. He had it as he
+went on: "Do we not brew within ourselves poisons which enter the
+circulation and pervade the system? A sudden emotion upsets the
+chemistry of the body. Or poisonous food. Or a drug. It affects many
+things. But we could never have had this chemical theory unless we had
+had physiological chemistry--and some carry it so far as to say that
+the brain secretes thought, just as the liver secretes bile, that
+thoughts are the results of molecular changes."
+
+"You are, then, a materialist of the most pronounced type," asserted
+Dr. Crafts.
+
+Kennedy had been reaching over to a table, toying with the phonograph.
+As Crafts spoke he moved a key, and I suspected that it was in order to
+catch the words.
+
+"Not entirely," he said. "No more than some eugenists."
+
+"In our field," put in Maude Schofield, "I might express the thought
+this way--the sociologist has had his day; now it is the biologist, the
+eugenist."
+
+"That expresses it," commented Kennedy, still tinkering with the
+record. "Yet it does not mean that because we have new ideas, they
+abolish the old. Often they only explain, amplify, supplement. For
+instance," he said, looking up at Edith Atherton, "take heredity. Our
+knowledge seems new, but is it? Marriages have always been dictated by
+a sort of eugenics. Society is founded on that."
+
+"Precisely," she answered. "The best families have always married into
+the best families. These modern notions simply recognize what the best
+people have always thought--except that it seems to me," she added with
+a sarcastic flourish, "people of no ancestry are trying to force
+themselves in among their betters."
+
+"Very true, Edith," drawled Burroughs, "but we did not have to be
+brought here by Quincy to learn that."
+
+Quincy Atherton had risen during the discussion and had approached
+Kennedy. Craig continued to finger the phonograph abstractedly, as he
+looked up.
+
+"About this--this insanity theory," he whispered eagerly. "You think
+that the suspicions I had have been justified?"
+
+I had been watching Kennedy's hand. As soon as Atherton had started to
+speak, I saw that Craig, as before, had moved the key, evidently
+registering what he said, as he had in the case of the others during
+the discussion.
+
+"One moment, Atherton," he whispered in reply, "I'm coming to that.
+Now," he resumed aloud, "there is a disease, or a number of diseases,
+to which my remarks about insanity a while ago might apply very well.
+They have been known for some time to arise from various affections of
+the thyroid glands in the neck. These glands, strange to say, if acted
+on in certain ways can cause degenerations of mind and body, which are
+well known, but in spite of much study are still very little
+understood. For example, there is a definite interrelation between them
+and sex--especially in woman."
+
+Rapidly he sketched what he had already told me of the thyroid and the
+hormones. "These hormones," added Kennedy, "are closely related to many
+reactions in the body, such as even the mother's secretion of milk at
+the proper time and then only. That and many other functions are due to
+the presence and character of these chemical secretions from the
+thyroid and other ductless glands. It is a fascinating study. For we
+know that anything that will upset--reduce or increase--the hormones is
+a matter intimately concerned with health. Such changes," he said
+earnestly, leaning forward, "might be aimed directly at the very heart
+of what otherwise would be a true eugenic marriage. It is even possible
+that loss of sex itself might be made to follow deep changes of the
+thyroid."
+
+He stopped a moment. Even if he had accomplished nothing else he had
+struck a note which had caused the Athertons to forget their former
+superciliousness.
+
+"If there is an oversupply of thyroid hormones," continued Craig, "that
+excess will produce many changes, for instance a condition very much
+like exophthalmic goiter. And," he said, straightening up, "I find that
+Eugenia Atherton has within her blood an undue proportion of these
+thyroid hormones. Now, is it overfunction of the glands,
+hyper-secretion--or is it something else?"
+
+No one moved as Kennedy skillfully led his disclosure along step by
+step.
+
+"That question," he began again slowly, shifting his position in the
+chair, "raises in my mind, at least, a question which has often
+occurred to me before. Is it possible for a person, taking advantage of
+the scientific knowledge we have gained, to devise and successfully
+execute a murder without fear of discovery? In other words, can a
+person be removed with that technical nicety of detail which will leave
+no clue and will be set down as something entirely natural, though
+unfortunate?"
+
+It was a terrible idea he was framing, and he dwelt on it so that we
+might accept it at its full value. "As one doctor has said," he added,
+"although toxicologists and chemists have not always possessed
+infallible tests for practical use, it is at present a pretty certain
+observation that every poison leaves its mark. But then on the other
+hand, students of criminology have said that a skilled physician or
+surgeon is about the only person now capable of carrying out a really
+scientific murder.
+
+"Which is true? It seems to me, at least in the latter case, that the
+very nicety of the handiwork must often serve as a clue in itself. The
+trained hand leaves the peculiar mark characteristic of its training.
+No matter how shrewdly the deed is planned, the execution of it is
+daily becoming a more and more difficult feat, thanks to our increasing
+knowledge of microbiology and pathology."
+
+He had risen, as he finished the sentence, every eye fixed on him, as
+if he had been a master hypnotist.
+
+"Perhaps," he said, taking off the cylinder from the phonograph and
+placing on one which I knew was that which had lain in the library
+closet over night, "perhaps some of the things I have said will explain
+or be explained by the record on this cylinder."
+
+He had started the machine. So magical was the effect on the little
+audience that I am tempted to repeat what I had already heard, but had
+not myself yet been able to explain:
+
+"How is she to-day?"
+
+"Not much changed--perhaps not so well."
+
+"It's all right, though. That is natural. It is working well. I think
+you might increase the dose one tablet."
+
+"You're sure it is all right?"
+
+"Oh, positively--it has been done in Europe."
+
+"I hope so. It must be a boy--and an ATHERTON."
+
+"Never fear."
+
+No one moved a muscle. If there was anyone in the room guilty of
+playing on the feelings and the health of an unfortunate woman, that
+person must have had superb control of his own feelings.
+
+"As you know," resumed Kennedy thoughtfully, "there are and have been
+many theories of sex control. One of the latest, but by no means the
+only one, is that it can be done by use of the extracts of various
+glands administered to the mother. I do not know with what scientific
+authority it was stated, but I do know that some one has recently said
+that adrenalin, derived from the suprarenal glands, induces boys to
+develop--cholin, from the bile of the liver, girls. It makes no
+difference--in this case. There may have been a show of science. But it
+was to cover up a crime. Some one has been administering to Eugenia
+Atherton tablets of thyroid extract--ostensibly to aid her in
+fulfilling the dearest ambition of her soul--to become the mother of a
+new line of Athertons which might bear the same relation to the future
+of the country as the great family of the Edwards mothered by Elizabeth
+Tuttle."
+
+He was bending over the two phonograph cylinders now, rapidly comparing
+the new one which he had made and that which he had just allowed to
+reel off its astounding revelation.
+
+"When a voice speaks into a phonograph," he said, half to himself, "its
+modulations received on the diaphragm are written by a needle point
+upon the surface of a cylinder or disk in a series of fine waving or
+zigzag lines of infinitely varying depth or breadth. Dr. Marage and
+others have been able to distinguish vocal sounds by the naked eye on
+phonograph records. Mr. Edison has studied them with the microscope in
+his world-wide search for the perfect voice.
+
+"In fact, now it is possible to identify voices by the records they
+make, to get at the precise meaning of each slightest variation of the
+lines with mathematical accuracy. They can no more be falsified than
+handwriting can be forged so that modern science cannot detect it or
+than typewriting can be concealed and attributed to another machine.
+The voice is like a finger print, a portrait parle--unescapable."
+
+He glanced up, then back again. "This microscope shows me," he said,
+"that the voices on that cylinder you heard are identical with two on
+this record which I have just made in this room."
+
+"Walter," he said, motioning to me, "look."
+
+I glanced into the eyepiece and saw a series of lines and curves,
+peculiar waves lapping together and making an appearance in some spots
+almost like tooth marks. Although I did not understand the details of
+the thing, I could readily see that by study one might learn as much
+about it as about loops, whorls, and arches on finger tips.
+
+"The upper and lower lines," he explained, "with long regular waves, on
+that highly magnified section of the record, are formed by the voice
+with no overtones. The three lines in the middle, with rhythmic
+ripples, show the overtones."
+
+He paused a moment and faced us. "Many a person," he resumed, "is a
+biotype in whom a full complement of what are called inhibitions never
+develops. That is part of your eugenics. Throughout life, and in spite
+of the best of training, that person reacts now and then to a certain
+stimulus directly. A man stands high; once a year he falls with a
+lethal quantity of alcohol. A woman, brilliant, accomplished, slips
+away and spends a day with a lover as unlike herself as can be imagined.
+
+"The voice that interests me most on these records," he went on,
+emphasizing the words with one of the cylinders which he still held,
+"is that of a person who has been working on the family pride of
+another. That person has persuaded the other to administer to Eugenia
+an extract because 'it must be a boy and an Atherton.' That person is a
+high-class defective, born with a criminal instinct, reacting to it in
+an artful way. Thank God, the love of a man whom theoretical eugenics
+condemned, roused us in--"
+
+A cry at the door brought us all to our feet, with hearts thumping as
+if they were bursting.
+
+It was Eugenia Atherton, wild-eyed, erect, staring.
+
+I stood aghast at the vision. Was she really to be the Lady Madeline in
+this fall of the House of Atherton?
+
+"Edith--I--I missed you. I heard voices. Is--is it true--what this
+man--says? Is my--my baby--"
+
+Quincy Atherton leaped forward and caught her as she reeled. Quickly
+Craig threw open a window for air, and as he did so leaned far out and
+blew shrilly on a police whistle.
+
+The young man looked up from Eugenia, over whom he was bending,
+scarcely heeding what else went on about him. Still, there was no trace
+of anger on his face, in spite of the great wrong that had been done
+him. There was room for only one great emotion--only anxiety for the
+poor girl who had suffered so cruelly merely for taking his name.
+
+Kennedy saw the unspoken question in his eyes.
+
+"Eugenia is a pure normal, as Dr. Crafts told you," he said gently. "A
+few weeks, perhaps only days, of treatment--the thyroid will revert to
+its normal state--and Eugenia Gilman will be the mother of a new house
+of Atherton which may eclipse even the proud record of the founder of
+the old."
+
+"Who blew the whistle?" demanded a gruff voice at the door, as a tall
+bluecoat puffed past the scandalized butler.
+
+"Arrest that woman," pointed Kennedy. "She is the poisoner. Either as
+wife of Burroughs, whom she fascinates and controls as she does Edith,
+she planned to break the will of Quincy or, in the other event, to
+administer the fortune as head of the Eugenics Foundation after the
+death of Dr. Crafts, who would have followed Eugenia and Quincy
+Atherton."
+
+I followed the direction of Kennedy's accusing finger. Maude
+Schofield's face betrayed more than even her tongue could have
+confessed.
+
+
+
+
+CHAPTER XXXIV
+
+THE BILLIONAIRE BABY
+
+
+Coming to us directly as a result of the talk that the Atherton case
+provoked was another that involved the happiness of a wealthy family to
+a no less degree.
+
+"I suppose you have heard of the 'billionaire baby,' Morton Hazleton
+III?" asked Kennedy of me one afternoon shortly afterward.
+
+The mere mention of the name conjured up in my mind a picture of the
+lusty two-year-old heir of two fortunes, as the feature articles in the
+Star had described that little scion of wealth--his luxurious nursery,
+his magnificent toys, his own motor car, a trained nurse and a
+detective on guard every hour of the day and night, every possible
+precaution for his health and safety.
+
+"Gad, what a lucky kid!" I exclaimed involuntarily.
+
+"Oh, I don't know about that," put in Kennedy. "The fortune may be
+exaggerated. His happiness is, I'm sure."
+
+He had pulled from his pocketbook a card and handed it to me. It read:
+"Gilbert Butler, American representative, Lloyd's."
+
+"Lloyd's?" I queried. "What has Lloyd's to do with the billion-dollar
+baby?"
+
+"Very much. The child has been insured with them for some fabulous sum
+against accident, including kidnaping."
+
+"Yes?" I prompted, "sensing" a story.
+
+"Well, there seem to have been threats of some kind, I understand. Mr.
+Butler has called on me once already to-day to retain my services and
+is going to--ah--there he is again now."
+
+Kennedy had answered the door buzzer himself, and Mr. Butler, a tall,
+sloping-shouldered Englishman, entered.
+
+"Has anything new developed?" asked Kennedy, introducing me.
+
+"I can't say," replied Butler dubiously. "I rather think we have found
+something that may have a bearing on the case. You know Miss Haversham,
+Veronica Haversham?"
+
+"The actress and professional beauty? Yes--at least I have seen her.
+Why?"
+
+"We hear that Morton Hazleton knows her, anyhow," remarked Butler dryly.
+
+"Well?"
+
+"Then you don't know the gossip?" he cut in. "She is said to be in a
+sanitarium near the city. I'll have to find that out for you. It's a
+fast set she has been traveling with lately, including not only
+Hazleton, but Dr. Maudsley, the Hazleton physician, and one or two
+others, who if they were poorer might be called desperate characters."
+
+"Does Mrs. Hazleton know of--of his reputed intimacy?"
+
+"I can't say that, either. I presume that she is no fool."
+
+Morton Hazleton, Jr., I knew, belonged to a rather smart group of young
+men. He had been mentioned in several near-scandals, but as far as I
+knew there had been nothing quite as public and definite as this one.
+
+"Wouldn't that account for her fears?" I asked.
+
+"Hardly," replied Butler, shaking his head. "You see, Mrs. Hazleton is
+a nervous wreck, but it's about the baby, and caused, she says, by her
+fears for its safety. It came to us only in a roundabout way, through a
+servant in the house who keeps us in touch. The curious feature is that
+we can seem to get nothing definite from her about her fears. They may
+be groundless."
+
+Butler shrugged his shoulders and proceeded, "And they may be
+well-founded. But we prefer to run no chances in a case of this kind.
+The child, you know, is guarded in the house. In his perambulator he is
+doubly guarded, and when he goes out for his airing in the automobile,
+two men, the chauffeur and a detective, are always there, besides his
+nurse, and often his mother or grandmother. Even in the nursery suite
+they have iron shutters which can be pulled down and padlocked at night
+and are constructed so as to give plenty of fresh air even to a
+scientific baby. Master Hazleton was the best sort of risk, we thought.
+But now--we don't know."
+
+"You can protect yourselves, though," suggested Kennedy.
+
+"Yes, we have, under the policy, the right to take certain measures to
+protect ourselves in addition to the precautions taken by the
+Hazletons. We have added our own detective to those already on duty.
+But we--we don't know what to guard against," he concluded, perplexed.
+"We'd like to know--that's all. It's too big a risk."
+
+"I may see Mrs. Hazleton?" mused Kennedy.
+
+"Yes. Under the circumstances she can scarcely refuse to see anyone we
+send. I've arranged already for you to meet her within an hour. Is that
+all right?"
+
+"Certainly."
+
+The Hazleton home in winter in the city was uptown, facing the river.
+The large grounds adjoining made the Hazletons quite independent of the
+daily infant parade which one sees along Riverside Drive.
+
+As we entered the grounds we could almost feel the very atmosphere on
+guard. We did not see the little subject of so much concern, but I
+remembered his much heralded advent, when his grandparents had settled
+a cold million on him, just as a reward for coming into the world.
+Evidently, Morton, Sr., had hoped that Morton, Jr., would calm down,
+now that there was a third generation to consider. It seemed that he
+had not. I wondered if that had really been the occasion of the threats
+or whatever it was that had caused Mrs. Hazleton's fears, and whether
+Veronica Haversham or any of the fast set around her had had anything
+to do with it.
+
+Millicent Hazleton was a very pretty little woman, in whom one saw
+instinctively the artistic temperament. She had been an actress, too,
+when young Morton Hazleton married her, and at first, at least, they
+had seemed very devoted to each other.
+
+We were admitted to see her in her own library, a tastefully furnished
+room on the second floor of the house, facing a garden at the side.
+
+"Mrs. Hazleton," began Butler, smoothing the way for us, "of course you
+realize that we are working in your interests. Professor Kennedy,
+therefore, in a sense, represents both of us."
+
+"I am quite sure I shall be delighted to help you," she said with an
+absent expression, though not ungraciously.
+
+Butler, having introduced us, courteously withdrew. "I leave this
+entirely in your hands," he said, as he excused himself. "If you want
+me to do anything more, call on me."
+
+I must say that I was much surprised at the way she had received us.
+Was there in it, I wondered, an element of fear lest if she refused to
+talk suspicion might grow even greater? One could see anxiety plainly
+enough on her face, as she waited for Kennedy to begin.
+
+A few moments of general conversation then followed.
+
+"Just what is it you fear?" he asked, after having gradually led around
+to the subject. "Have there been any threatening letters?"
+
+"N-no," she hesitated, "at least nothing--definite."
+
+"Gossip?" he hinted.
+
+"No." She said it so positively that I fancied it might be taken for a
+plain "Yes."
+
+"Then what is it?" he asked, very deferentially, but firmly.
+
+She had been looking out at the garden. "You couldn't understand," she
+remarked. "No detective--" she stopped.
+
+"You may be sure, Mrs. Hazleton, that I have not come here
+unnecessarily to intrude," he reassured her. "It is exactly as Mr.
+Butler put it. We--want to help you."
+
+I fancied there seemed to be something compelling about his manner. It
+was at once sympathetic and persuasive. Quite evidently he was taking
+pains to break down the prejudice in her mind which she had already
+shown toward the ordinary detective.
+
+"You would think me crazy," she remarked slowly. "But it is just a--a
+dream--just dreams."
+
+I don't think she had intended to say anything, for she stopped short
+and looked at him quickly as if to make sure whether he could
+understand. As for myself, I must say I felt a little skeptical. To my
+surprise, Kennedy seemed to take the statement at its face value.
+
+"Ah," he remarked, "an anxiety dream? You will pardon me, Mrs.
+Hazleton, but before we go further let me tell you frankly that I am
+much more than an ordinary detective. If you will permit me, I should
+rather have you think of me as a psychologist, a specialist, one who
+has come to set your mind at rest rather than to worm things from you
+by devious methods against which you have to be on guard. It is just
+for such an unusual case as yours that Mr. Butler has called me in. By
+the way, as our interview may last a few minutes, would you mind
+sitting down? I think you'll find it easier to talk if you can get your
+mind perfectly at rest, and for the moment trust to the nurse and the
+detectives who are guarding the garden, I am sure, perfectly."
+
+She had been standing by the window during the interview and was quite
+evidently growing more and more nervous. With a bow Kennedy placed her
+at her ease on a chaise lounge.
+
+"Now," he continued, standing near her, but out of sight, "you must try
+to remain free from all external influences and impressions. Don't
+move. Avoid every use of a muscle. Don't let anything distract you.
+Just concentrate your attention on your psychic activities. Don't
+suppress one idea as unimportant, irrelevant, or nonsensical. Simply
+tell me what occurs to you in connection with the dreams--everything,"
+emphasized Craig.
+
+I could not help feeling surprised to find that she accepted Kennedy's
+deferential commands, for after all that was what they amounted to.
+Almost I felt that she was turning to him for help, that he had broken
+down some barrier to her confidence. He seemed to exert a sort of
+hypnotic influence over her.
+
+"I have had cases before which involved dreams," he was saying quietly
+and reassuringly. "Believe me, I do not share the world's opinion that
+dreams are nothing. Nor yet do I believe in them superstitiously. I can
+readily understand how a dream can play a mighty part in shaping the
+feelings of a high-tensioned woman. Might I ask exactly what it is you
+fear in your dreams?"
+
+She sank her head back in the cushions, and for a moment closed her
+eyes, half in weariness, half in tacit obedience to him. "Oh, I have
+such horrible dreams," she said at length, "full of anxiety and fear
+for Morton and little Morton. I can't explain it. But they are so
+horrible."
+
+Kennedy said nothing. She was talking freely at last.
+
+"Only last night," she went on, "I dreamt that Morton was dead. I could
+see the funeral, all the preparations, and the procession. It seemed
+that in the crowd there was a woman. I could not see her face, but she
+had fallen down and the crowd was around her. Then Dr. Maudsley
+appeared. Then all of a sudden the dream changed. I thought I was on
+the sand, at the seashore, or perhaps a lake. I was with Junior and it
+seemed as if he were wading in the water, his head bobbing up and down
+in the waves. It was like a desert, too--the sand. I turned, and there
+was a lion behind me. I did not seem to be afraid of him, although I
+was so close that I could almost feel his shaggy mane. Yet I feared
+that he might bite Junior. The next I knew I was running with the child
+in my arms. I escaped--and--oh, the relief!"
+
+She sank back, half exhausted, half terrified still by the recollection.
+
+"In your dream when Dr. Maudsley appeared," asked Kennedy, evidently
+interested in filling in the gap, "what did he do?"
+
+"Do?" she repeated. "In the dream? Nothing."
+
+"Are you sure?" he asked, shooting a quick glance at her.
+
+"Yes. That part of the dream became indistinct. I'm sure he did
+nothing, except shoulder through the crowd. I think he had just
+entered. Then that part of the dream seemed to end and the second part
+began."
+
+Piece by piece Kennedy went over it, putting it together as if it were
+a mosaic.
+
+"Now, the woman. You say her face was hidden?"
+
+She hesitated. "N--no. I saw it. But it was no one I knew."
+
+Kennedy did not dwell on the contradiction, but added, "And the crowd?"
+
+"Strangers, too."
+
+"Dr. Maudsley is your family physician?" he questioned.
+
+"Yes."
+
+"Did he call--er--yesterday?"
+
+"He calls every day to supervise the nurse who has Junior in charge."
+
+"Could one always be true to oneself in the face of any temptation?" he
+asked suddenly.
+
+It was a bold question. Yet such had been the gradual manner of his
+leading up to it that, before she knew it, she had answered quite
+frankly, "Yes--if one always thought of home and her child, I cannot
+see how one could help controlling herself."
+
+She seemed to catch her breath, almost as though the words had escaped
+her before she knew it.
+
+"Is there anything besides your dream that alarms you," he asked,
+changing the subject quickly, "any suspicion of--say the servants?"
+
+"No," she said, watching him now. "But some time ago we caught a
+burglar upstairs here. He managed to escape. That has made me nervous.
+I didn't think it was possible."
+
+"Anything else?"
+
+"No," she said positively, this time on her guard.
+
+Kennedy saw that she had made up her mind to say no more.
+
+"Mrs. Hazleton," he said, rising. "I can hardly thank you too much for
+the manner in which you have met my questions. It will make it much
+easier for me to quiet your fears. And if anything else occurs to you,
+you may rest assured I shall violate no confidences in your telling me."
+
+I could not help the feeling, however, that there was just a little air
+of relief on her face as we left.
+
+
+
+
+CHAPTER XXXV
+
+THE PSYCHANALYSIS
+
+
+"H--M," mused Kennedy as we walked along after leaving the house.
+"There were several 'complexes,' as they are called, there--the most
+interesting and important being the erotic, as usual. Now, take the
+lion in the dream, with his mane. That, I suspect, was Dr. Maudsley. If
+you are acquainted with him, you will recall his heavy, almost tawny
+beard."
+
+Kennedy seemed to be revolving something in his mind and I did not
+interrupt. I had known him too long to feel that even a dream might not
+have its value with him. Indeed, several times before he had given me
+glimpses into the fascinating possibilities of the new psychology.
+
+"In spite of the work of thousands of years, little progress has been
+made in the scientific understanding of dreams," he remarked a few
+moments later. "Freud, of Vienna--you recall the name?--has done most,
+I think in that direction."
+
+I recalled something of the theories of the Freudists, but said nothing.
+
+"It is an unpleasant feature of his philosophy," he went on, "but Freud
+finds the conclusion irresistible that all humanity underneath the
+shell is sensuous and sensual in nature. Practically all dreams betray
+some delight of the senses and sexual dreams are a large proportion.
+There is, according to the theory, always a wish hidden or expressed in
+a dream. The dream is one of three things, the open, the disguised or
+the distorted fulfillment of a wish, sometimes recognized, sometimes
+repressed.
+
+"Anxiety dreams are among the most interesting and important Anxiety
+may originate in psycho-sexual excitement, the repressed libido, as the
+Freudists call it. Neurotic fear has its origin in sexual life and
+corresponds to a libido which has been turned away from its object and
+has not succeeded in being applied. All so-called day dreams of women
+are erotic; of men they are either ambition or love.
+
+"Often dreams, apparently harmless, turn out to be sinister if we take
+pains to interpret them. All have the mark of the beast. For example,
+there was that unknown woman who had fallen down and was surrounded by
+a crowd. If a woman dreams that, it is sexual. It can mean only a
+fallen woman. That is the symbolism. The crowd always denotes a secret.
+
+"Take also the dream of death. If there is no sorrow felt, then there
+is another cause for it. But if there is sorrow, then the dreamer
+really desires death or absence. I expect to have you quarrel with
+that. But read Freud, and remember that in childhood death is
+synonymous with being away. Thus for example, if a girl dreams that her
+mother is dead, perhaps it means only that she wishes her away so that
+she can enjoy some pleasure that her strict parent, by her presence,
+denies.
+
+"Then there was that dream about the baby in the water. That, I think,
+was a dream of birth. You see, I asked her practically to repeat the
+dreams because there were several gaps. At such points one usually
+finds first hesitation, then something that shows one of the main
+complexes. Perhaps the subject grows angry at the discovery.
+
+"Now, from the tangle of the dream thought, I find that she fears that
+her husband is too intimate with another woman, and that perhaps
+unconsciously she has turned to Dr. Maudsley for sympathy. Dr.
+Maudsley, as I said, is not only bearded, but somewhat of a social
+lion. He had called on her the day before. Of such stuff are all dream
+lions when there is no fear. But she shows that she has been guilty of
+no wrongdoing--she escaped, and felt relieved."
+
+"I'm glad of that," I put in. "I don't like these scandals. On the Star
+when I have to report them, I do it always under protest. I don't know
+what your psychanalysis is going to show in the end, but I for one have
+the greatest sympathy for that poor little woman in the big house
+alone, surrounded by and dependent on servants, while her husband is
+out collecting scandals."
+
+"Which suggests our next step," he said, turning the subject. "I hope
+that Butler has found out the retreat of Veronica Haversham."
+
+We discovered Miss Haversham at last at Dr. Klemm's sanitarium, up in
+the hills of Westchester County, a delightful place with a reputation
+for its rest cures. Dr. Klemm was an old friend of Kennedy's, having
+had some connection with the medical school at the University.
+
+She had gone up there rather suddenly, it seemed, to recuperate. At
+least that was what was given out, though there seemed to be much
+mystery about her, and she was taking no treatment as far as was known.
+
+"Who is her physician?" asked Kennedy of Dr. Klemm as we sat in his
+luxurious office.
+
+"A Dr. Maudsley of the city."
+
+Kennedy glanced quickly at me in time to check an exclamation.
+
+"I wonder if I could see her?"
+
+"Why, of course--if she is willing," replied Dr. Klemm.
+
+"I will have to have some excuse," ruminated Kennedy. "Tell her I am a
+specialist in nervous troubles from the city, have been visiting one of
+the other patients, anything."
+
+Dr. Klemm pulled down a switch on a large oblong oak box on his desk,
+asked for Miss Haversham, and waited a moment.
+
+"What is that?" I asked.
+
+"A vocaphone," replied Kennedy. "This sanitarium is quite up to date,
+Klemm."
+
+The doctor nodded and smiled. "Yes, Kennedy," he replied.
+"Communicating with every suite of rooms we have the vocaphone. I find
+it very convenient to have these microphones, as I suppose you would
+call them, catching your words without talking into them directly as
+you have to do in the telephone and then at the other end emitting the
+words without the use of an earpiece, from the box itself, as if from a
+megaphone horn. Miss Haversham, this is Dr. Klemm. There is a Dr.
+Kennedy here visiting another patient, a specialist from New York. He'd
+like very much to see you if you can spare a few minutes."
+
+"Tell him to come up." The voice seemed to come from the vocaphone as
+though she were in the room with us.
+
+Veronica Haversham was indeed wonderful, one of the leading figures in
+the night life of New York, a statuesque brunette of striking beauty,
+though I had heard of often ungovernable temper. Yet there was
+something strange about her face here. It seemed perhaps a little
+yellow, and I am sure that her nose had a peculiar look as if she were
+suffering from an incipient rhinitis. The pupils of her eyes were as
+fine as pin heads, her eyebrows were slightly elevated. Indeed, I felt
+that she had made no mistake in taking a rest if she would preserve the
+beauty which had made her popularity so meteoric.
+
+"Miss Haversham," began Kennedy, "they tell me that you are suffering
+from nervousness. Perhaps I can help you. At any rate it will do no
+harm to try. I know Dr. Maudsley well, and if he doesn't approve--well,
+you may throw the treatment into the waste basket."
+
+"I'm sure I have no reason to refuse," she said. "What would you
+suggest?"
+
+"Well, first of all, there is a very simple test I'd like to try. You
+won't find that it bothers you in the least--and if I can't help you,
+then no harm is done."
+
+Again I watched Kennedy as he tactfully went through the preparations
+for another kind of psychanalysis, placing Miss Haversham at her ease
+on a davenport in such a way that nothing would distract her attention.
+As she reclined against the leather pillows in the shadow it was not
+difficult to understand the lure by which she held together the little
+coterie of her intimates. One beautiful white arm, bare to the elbow,
+hung carelessly over the edge of the davenport, displaying a plain gold
+bracelet.
+
+"Now," began Kennedy, on whom I knew the charms of Miss Haversham
+produced a negative effect, although one would never have guessed it
+from his manner, "as I read off from this list of words, I wish that
+you would repeat the first thing, anything," he emphasized, "that comes
+into your head, no matter how trivial it may seem. Don't force yourself
+to think. Let your ideas flow naturally. It depends altogether on your
+paying attention to the words and answering as quickly as you
+can--remember, the first word that comes into your mind. It is easy to
+do. We'll call it a game," he reassured.
+
+Kennedy handed a copy of the list to me to record the answers. There
+must have been some fifty words, apparently senseless, chosen at
+random, it seemed. They were:
+
+
+ head to dance salt white lie
+
+ green sick new child to fear
+
+ water pride to pray sad stork
+
+ to sing ink money to marry false
+
+ death angry foolish dear anxiety
+
+ long needle despise to quarrel to kiss
+
+ ship voyage finger old bride
+
+ to pay to sin expensive family pure
+
+ window bread to fall friend ridicule
+
+ cold rich unjust luck to sleep
+
+
+"The Jung association word test is part of the Freud psychanalysis,
+also," he whispered to me, "You remember we tried something based on
+the same idea once before?"
+
+I nodded. I had heard of the thing in connection with blood-pressure
+tests, but not this way.
+
+Kennedy called out the first word, "Head," while in his hand he held a
+stop watch which registered to one-fifth of a second.
+
+Quickly she replied, "Ache," with an involuntary movement of her hand
+toward her beautiful forehead.
+
+"Good," exclaimed Kennedy. "You seem to grasp the idea better than most
+of my patients."
+
+I had recorded the answer, he the time, and we found out, I recall
+afterward, that the time averaged something like two and two-fifths
+seconds.
+
+I thought her reply to the second word, "green," was curious. It came
+quickly, "Envy."
+
+However, I shall not attempt to give all the replies, but merely some
+of the most significant. There did not seem to be any hesitation about
+most of the words, but whenever Kennedy tried to question her about a
+word that seemed to him interesting she made either evasive or
+hesitating answers, until it became evident that in the back of her
+head was some idea which she was repressing and concealing from us,
+something that she set off with a mental "No Thoroughfare."
+
+He had finished going through the list, and Kennedy was now studying
+over the answers and comparing the time records.
+
+"Now," he said at length, running his eye over the words again, "I want
+to repeat the performance. Try to remember and duplicate your first
+replies," he said.
+
+Again we went through what at first had seemed to me to be a solemn
+farce, but which I began to see was quite important. Sometimes she
+would repeat the answer exactly as before. At other times a new word
+would occur to her. Kennedy was keen to note all the differences in the
+two lists.
+
+One which I recall because the incident made an impression on me had to
+do with the trio, "Death--life--inevitable."
+
+"Why that?" he asked casually.
+
+"Haven't you ever heard the saying, 'One should let nothing which one
+can have escape, even if a little wrong is done; no opportunity should
+be missed; life is so short, death inevitable'?"
+
+There were several others which to Kennedy seemed more important, but
+long after we had finished I pondered this answer. Was that her
+philosophy of life? Undoubtedly she would never have remembered the
+phrase if it had not been so, at least in a measure.
+
+She had begun to show signs of weariness, and Kennedy quickly brought
+the conversation around to subjects of apparently a general nature, but
+skillfully contrived so as to lead the way along lines her answers had
+indicated.
+
+Kennedy had risen to go, still chatting. Almost unintentionally he
+picked up from a dressing table a bottle of white tablets, without a
+label, shaking it to emphasize an entirely, and I believe purposely,
+irrelevant remark.
+
+"By the way," he said, breaking off naturally, "what is that?"
+
+"Only something Dr. Maudsley had prescribed for me," she answered
+quickly.
+
+As he replaced the bottle and went on with the thread of the
+conversation, I saw that in shaking the bottle he had abstracted a
+couple of the tablets before she realized it. "I can't tell you just
+what to do without thinking the case over," he concluded, rising to go.
+"Yours is a peculiar case, Miss Haversham, baffling. I'll have to study
+it over, perhaps ask Dr. Maudsley If I may see you again. Meanwhile, I
+am sure what he is doing is the correct thing."
+
+Inasmuch as she had said nothing about what Dr. Maudsley was doing, I
+wondered whether there was not just a trace of suspicion in her glance
+at him from under her long dark lashes.
+
+"I can't see that you have done anything," she remarked pointedly. "But
+then doctors are queer--queer."
+
+That parting shot also had in it, for me, something to ponder over. In
+fact I began to wonder if she might not be a great deal more clever
+than even Kennedy gave her credit for being, whether she might not have
+submitted to his tests for pure love of pulling the wool over his eyes.
+
+Downstairs again, Kennedy paused only long enough to speak a few words
+with his friend Dr. Klemm.
+
+"I suppose you have no idea what Dr. Maudsley has prescribed for her?"
+he asked carelessly.
+
+"Nothing, as far as I know, except rest and simple food."
+
+He seemed to hesitate, then he said under his voice, "I suppose you
+know that she is a regular dope fiend, seasons her cigarettes with
+opium, and all that."
+
+"I guessed as much," remarked Kennedy, "but how does she get it here?"
+
+"She doesn't."
+
+"I see," remarked Craig, apparently weighing now the man before him. At
+length he seemed to decide to risk something.
+
+"Klemm," he said, "I wish you would do something for me. I see you have
+the vocaphone here. Now if--say Hazleton--should call--will you listen
+in on that vocaphone for me?" Dr. Klemm looked squarely at him.
+
+"Kennedy," he said, "it's unprofessional, but---"
+
+"So it is to let her be doped up under guise of a cure."
+
+"What?" he asked, startled. "She's getting the stuff now?"
+
+"No, I didn't say she was getting opium, or from anyone here. All the
+same, if you would just keep an ear open---"
+
+"It's unprofessional, but--you'd not ask it without a good reason. I'll
+try."
+
+It was very late when we got back to the city and we dined at an uptown
+restaurant which we had almost to ourselves.
+
+Kennedy had placed the little whitish tablets in a small paper packet
+for safe keeping. As we waited for our order he drew one from his
+pocket, and after looking at it a moment crushed it to a powder in the
+paper.
+
+"What is it?" I asked curiously. "Cocaine?"
+
+"No," he said, shaking his head doubtfully.
+
+He had tried to dissolve a little of the powder in some water from the
+glass before him, but it would not dissolve.
+
+As he continued to look at it his eye fell on the cut-glass vinegar
+cruet before us. It was full of the white vinegar.
+
+"Really acetic acid," he remarked, pouring out a little.
+
+The white powder dissolved.
+
+For several minutes he continued looking at the stuff.
+
+"That, I think," he remarked finally, "is heroin."
+
+"More 'happy dust'?" I replied with added interest now, thinking of our
+previous case. "Is the habit so extensive?"
+
+"Yes," he replied, "the habit is comparatively new, although in Paris,
+I believe, they call the drug fiends, 'heroinomaniacs.' It is, as I
+told you before, a derivative of morphine. Its scientific name is
+diacetyl-morphin. It is New York's newest peril, one of the most
+dangerous drugs yet. Thousands are slaves to it, although its sale is
+supposedly restricted. It is rotting the heart out of the Tenderloin.
+Did you notice Veronica Haversham's yellowish whiteness, her down-drawn
+mouth, elevated eyebrows, and contracted eyes? She may have taken it up
+to escape other drugs. Some people have--and have just got a new habit.
+It can be taken hypodermically, or in a tablet, or by powdering the
+tablet to a white crystalline powder and snuffing up the nose. That's
+the way she takes it. It produces rhinitis of the nasal passages, which
+I see you observed, but did not understand. It has a more profound
+effect than morphine, and is ten times as powerful as codeine. And one
+of the worst features is that so many people start with it, thinking it
+is as harmless as it has been advertised. I wouldn't be surprised if
+she used from seventy-five to a hundred one-twelfth grain tablets a
+day. Some of them do, you know."
+
+"And Dr. Maudsley," I asked quickly, "do you think it is through him or
+in spite of him?"
+
+"That's what I'd like to know. About those words," he continued, "what
+did you make of the list and the answers?"
+
+I had made nothing and said so, rather quickly.
+
+"Those," he explained, "were words selected and arranged to strike
+almost all the common complexes in analyzing and diagnosing. You'd
+think any intelligent person could give a fluent answer to them,
+perhaps a misleading answer. But try it yourself, Walter. You'll find
+you can't. You may start all right, but not all the words will be
+reacted to in the same time or with the same smoothness and ease. Yet,
+like the expressions of a dream, they often seem senseless. But they
+have a meaning as soon as they are 'psychanalyzed.' All the mistakes in
+answering the second time, for example, have a reason, if we can only
+get at it. They are not arbitrary answers, but betray the inmost
+subconscious thoughts, those things marked, split off from
+consciousness and repressed into the unconscious. Associations, like
+dreams, never lie. You may try to conceal the emotions and unconscious
+actions, but you can't."
+
+I listened, fascinated by Kennedy's explanation.
+
+"Anyone can see that that woman has something on her mind besides the
+heroin habit. It may be that she is trying to shake the habit off in
+order to do it; it may be that she seeks relief from her thoughts by
+refuge in the habit; and it may be that some one has purposely caused
+her to contract this new habit in the guise of throwing off an old. The
+only way by which to find out is to study the case."
+
+He paused. He had me keenly on edge, but I knew that he was not yet in
+a position to answer his queries positively.
+
+"Now I found," he went on, "that the religious complexes were extremely
+few; as I expected the erotic were many. If you will look over the
+three lists you will find something queer about every such word as,
+'child, 'to marry,' 'bride,' 'to lie,' 'stork,' and so on. We're on the
+right track. That woman does know something about that child."
+
+"My eye catches the words 'to sin,' 'to fall,' 'pure,' and others," I
+remarked, glancing over the list.
+
+"Yes, there's something there, too. I got the hint for the drug from
+her hesitation over 'needle' and 'white.' But the main complex has to
+do with words relating to that child and to love. In short, I think we
+are going to find it to be the reverse of the rule of the French, that
+it will be a case of 'cherchez l'homme.'"
+
+Early the next day Kennedy, after a night of studying over the case,
+journeyed up to the sanitarium again. We found Dr. Klemm eager to meet
+us.
+
+"What is it?" asked Kennedy, equally eager.
+
+"I overheard some surprising things over the vocaphone," he hastened.
+"Hazleton called. Why, there must have been some wild orgies in that
+precious set of theirs, and, would you believe it, many of them seem to
+have been at what Dr. Maudsley calls his 'stable studio,' a den he has
+fixed up artistically over his garage on a side street."
+
+"Indeed?"
+
+"I couldn't get it all, but I did hear her repeating over and over to
+Hazleton, 'Aren't you all mine? Aren't you all mine?' There must be
+some vague jealousy lurking in the heart of that ardent woman. I can't
+figure it out."
+
+"I'd like to see her again," remarked Kennedy. "Will you ask her if I
+may?"
+
+
+
+
+CHAPTER XXXVI
+
+THE ENDS OF JUSTICE
+
+
+A few minutes later we were in the sitting room of her suite. She
+received us rather ungraciously, I thought.
+
+"Do you feel any better?" asked Kennedy.
+
+"No," she replied curtly. "Excuse me for a moment. I wish to see that
+maid of mine. Clarisse!"
+
+She had hardly left the room when Kennedy was on his feet. The bottle
+of white tablets, nearly empty, was still on the table. I saw him take
+some very fine white powder and dust it quickly over the bottle. It
+seemed to adhere, and from his pocket he quickly drew a piece of what
+seemed to be specially prepared paper, laid it over the bottle where
+the powder adhered, fitting it over the curves. He withdrew it quickly,
+for outside we heard her light step, returning. I am sure she either
+saw or suspected that Kennedy had been touching the bottle of tablets,
+for there was a look of startled fear on her face.
+
+"Then you do not feel like continuing the tests we abandoned last
+night?" asked Kennedy, apparently not noticing her look.
+
+"No, I do not," she almost snapped. "You--you are detectives. Mrs.
+Hazleton has sent you."
+
+"Indeed, Mrs. Hazleton has not sent us," insisted Kennedy, never for an
+instant showing his surprise at her mention of the name.
+
+"You are. You can tell her, you can tell everybody. I'll tell--I'll
+tell myself. I won't wait. That child is mine--mine--not hers. Now--go!"
+
+Veronica Haversham on the stage never towered in a fit of passion as
+she did now in real life, as her ungovernable feelings broke forth
+tempestuously on us.
+
+I was astounded, bewildered at the revelation, the possibilities in
+those simple words, "The child is mine." For a moment I was stunned.
+Then as the full meaning dawned on me I wondered in a flood of
+consciousness whether it was true. Was it the product of her
+drug-disordered brain? Had her desperate love for Hazleton produced a
+hallucination?
+
+Kennedy, silent, saw that the case demanded quick action. I shall never
+forget the breathless ride down from the sanitarium to the Hazleton
+house on Riverside Drive.
+
+"Mrs. Hazleton," he cried, as we hurried in, "you will pardon me for
+this unceremonious intrusion, but it is most important. May I trouble
+you to place your fingers on this paper--so?"
+
+He held out to her a piece of the prepared paper. She looked at him
+once, then saw from his face that he was not to be questioned. Almost
+tremulously she did as he said, saying not a word. I wondered whether
+she knew the story of Veronica, or whether so far only hints of it had
+been brought to her.
+
+"Thank you," he said quickly. "Now, if I may see Morton?"
+
+It was the first time we had seen the baby about whom the rapidly
+thickening events were crowding. He was a perfect specimen of
+well-cared-for, scientific infant.
+
+Kennedy took the little chubby fingers playfully in his own. He seemed
+at once to win the child's confidence, though he may have violated
+scientific rules. One by one he pressed the little fingers on the
+paper, until little Morton crowed with delight as one little piggy
+after another "went to market." He had deserted thousands of dollars'
+worth of toys just to play with the simple piece of paper Kennedy had
+brought with him. As I looked at him, I thought of what Kennedy had
+said at the start. Perhaps this innocent child was not to be envied
+after all. I could hardly restrain my excitement over the astounding
+situation which had suddenly developed.
+
+"That will do," announced Kennedy finally, carelessly folding up the
+paper and slipping it into his pocket. "You must excuse me now."
+
+"You see," he explained on the way to the laboratory, "that powder
+adheres to fresh finger prints, taking all the gradations. Then the
+paper with its paraffine and glycerine coating takes off the powder."
+
+In the laboratory he buried himself in work, with microscope compasses,
+calipers, while I fumed impotently at the window.
+
+"Walter," he called suddenly, "get Dr. Maudsley on the telephone. Tell
+him to come immediately to the laboratory."
+
+Meanwhile Kennedy was busy arranging what he had discovered in logical
+order and putting on it the finishing touches.
+
+As Dr. Maudsley entered Kennedy greeted him and began by plunging
+directly into the case in answer to his rather discourteous inquiry as
+to why he had been so hastily summoned.
+
+"Dr. Maudsley," said Craig, "I have asked you to call alone because,
+while I am on the verge of discovering the truth in an important case
+affecting Morton Hazleton and his wife, I am frankly perplexed as to
+how to go ahead."
+
+The doctor seemed to shake with excitement as Kennedy proceeded.
+
+"Dr. Maudsley," Craig added, dropping his voice, "is Morton III the son
+of Millicent Hazleton or not? You were the physician in attendance on
+her at the birth. Is he?"
+
+Maudsley had been watching Kennedy furtively at first, but as he rapped
+out the words I thought the doctor's eyes would pop out of his head.
+Perspiration in great beads collected on his face.
+
+"P--professor K--Kennedy," he muttered, frantically rubbing his face
+and lower jaw as if to compose the agitation he could so ill conceal,
+"let me explain."
+
+"Yes, yes--go on," urged Kennedy.
+
+"Mrs. Hazleton's baby was born--dead. I knew how much she and the rest
+of the family had longed for an heir, how much it meant. And
+I--substituted for the dead child a newborn baby from the maternity
+hospital. It--it belonged to Veronica Haversham--then a poor chorus
+girl. I did not intend that she should ever know it. I intended that
+she should think her baby was dead. But in some way she found out.
+Since then she has become a famous beauty, has numbered among her
+friends even Hazleton himself. For nearly two years I have tried to
+keep her from divulging the secret. From time to time hints of it have
+leaked out. I knew that if Hazleton with his infatuation of her were to
+learn---"
+
+"And Mrs. Hazleton, has she been told?" interrupted Kennedy.
+
+"I have been trying to keep it from her as long as I can, but it has
+been difficult to keep Veronica from telling it. Hazleton himself was
+so wild over her. And she wanted her son as she---"
+
+"Maudsley," snapped out Kennedy, slapping down on the table the mass of
+prints and charts which he had hurriedly collected and was studying,
+"you lie! Morton is Millicent Hazleton's son. The whole story is
+blackmail. I knew it when she told me of her dreams and I suspected
+first some such devilish scheme as yours. Now I know it scientifically."
+
+He turned over the prints.
+
+"I suppose that study of these prints, Maudsley, will convey nothing to
+you. I know that it is usually stated that there are no two sets of
+finger prints in the world that are identical or that can be confused.
+Still, there are certain similarities of finger prints and other
+characteristics, and these similarities have recently been exhaustively
+studied by Bertilion, who has found that there are clear relationships
+sometimes between mother and child in these respects. If Solomon were
+alive, doctor, he would not now have to resort to the expedient to
+which he did when the two women disputed over the right to the living
+child. Modern science is now deciding by exact laboratory methods the
+same problem as he solved by his unique knowledge of feminine
+psychology.
+
+"I saw how this case was tending. Not a moment too soon, I said to
+myself, 'The hand of the child will tell.' By the very variations in
+unlike things, such as finger and palm prints, as tabulated and
+arranged by Bertillon after study in thousands of cases, by the very
+loops, whorls, arches and composites, I have proved my case.
+
+"The dominancy, not the identity, of heredity through the infinite
+varieties of finger markings is sometimes very striking. Unique
+patterns in a parent have been repeated with marvelous accuracy in the
+child. I knew that negative results might prove nothing in regard to
+parentage, a caution which it is important to observe. But I was
+prepared to meet even that.
+
+"I would have gone on into other studies, such as Tammasia's, of
+heredity in the veining of the back of the hands; I would have measured
+the hands, compared the relative proportion of the parts; I would have
+studied them under the X-ray as they are being studied to-day; I would
+have tried the Reichert blood crystal test which is being perfected now
+so that it will tell heredity itself. There is no scientific stone I
+would have left unturned until I had delved at the truth of this
+riddle. Fortunately it was not necessary. Simple finger prints have
+told me enough. And best of all, it has been in time to frustrate that
+devilish scheme you and Veronica Haversham have been slowly unfolding."
+
+Maudsley crumpled up, as it were, at Kennedy's denunciation. He seemed
+to shrink toward the door.
+
+"Yes," cried Kennedy, with extended forefinger, "you may go--for the
+present. Don't try to run away. You're watched from this moment on."
+
+Maudsley had retreated precipitately.
+
+I looked at Kennedy inquiringly. What to do? It was indeed a delicate
+situation, requiring the utmost care to handle. If the story had been
+told to Hazleton, what might he not have already done? He must be found
+first of all if we were to meet the conspiracy of these two.
+
+Kennedy reached quickly for the telephone. "There is one stream of
+scandal that can be dammed at its source," he remarked, calling a
+number. "Hello. Klemm's Sanitarium? I'd like to speak with Miss
+Haversham. What--gone? Disappeared? Escaped?"
+
+He hung up the receiver and looked at me blankly. I was speechless.
+
+A thousand ideas flew through our minds at once. Had she perceived the
+import of our last visit and was she now on her way to complete her
+plotted slander of Millicent Hazleton, though it pulled down on herself
+in the end the whole structure?
+
+Hastily Kennedy called Hazleton's home, Butler, and one after another
+of Hazleton's favorite clubs. It was not until noon that Butler himself
+found him and came with him, under protest, to the laboratory.
+
+"What is it--what have you found?" cried Butler, his lean form a-quiver
+with suppressed excitement.
+
+Briefly, one fact after another, sparing Hazleton nothing, Kennedy
+poured forth the story, how by hint and innuendo Maudsley had been
+working on Millicent, undermining her, little knowing that he had
+attacked in her a very tower of strength, how Veronica, infatuated by
+him, had infatuated him, had led him on step by step.
+
+Pale and agitated, with nerves unstrung by the life he had been
+leading, Hazleton listened. And as Kennedy hammered one fact after
+another home, he clenched his fists until the nails dug into his very
+palms.
+
+"The scoundrels," he ground out, as Kennedy finished by painting the
+picture of the brave little broken-hearted woman fighting off she knew
+not what, and the golden-haired, innocent baby stretching out his arms
+in glee at the very chance to prove that he was what he was. "The
+scoundrels--take me to Maudsley now. I must see Maudsley. Quick!"
+
+As we pulled up before the door of the reconstructed stable-studio,
+Kennedy jumped out. The door was unlocked. Up the broad flight of
+stairs, Hazleton went two at a time. We followed him closely.
+
+Lying on the divan in the room that had been the scene of so many
+orgies, locked in each other's arms, were two figures--Veronica
+Haversham and Dr. Maudsley.
+
+She must have gone there directly after our visit to Dr. Klemm's, must
+have been waiting for him when he returned with his story of the
+exposure to answer her fears of us as Mrs. Hazleton's detectives. In a
+frenzy of intoxication she must have flung her arms blindly about him
+in a last wild embrace.
+
+Hazleton looked, aghast.
+
+He leaned over and took her arm. Before he could frame the name,
+"Veronica!" he had recoiled.
+
+The two were cold and rigid.
+
+"An overdose of heroin this time," muttered Kennedy.
+
+My head was in a whirl.
+
+Hazleton stared blankly at the two figures abjectly lying before him,
+as the truth burned itself indelibly into his soul. He covered his face
+with his hands. And still he saw it all.
+
+Craig said nothing. He was content to let what he had shown work in the
+man's mind.
+
+"For the sake of--that baby--would she--would she forgive?" asked
+Hazleton, turning desperately toward Kennedy.
+
+Deliberately Kennedy faced him, not as scientist and millionaire, but
+as man and man.
+
+"From my psychanalysis," he said slowly, "I should say that it IS
+within your power, in time, to change those dreams."
+
+Hazleton grasped Kennedy's hand before he knew it.
+
+"Kennedy--home--quick. This is the first manful impulse I have had for
+two years. And, Jameson--you'll tone down that part of it in the
+newspapers that Junior--might read--when he grows up?"

+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or

+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.

+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation information page at www.gutenberg.org
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation

+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent

+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit www.gutenberg.org/donate
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: www.gutenberg.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For forty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+Most people start at our Web site which has the main PG search facility:
+
+ www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.

+INTRODUCTION
+
+
+As I look back now on the sensational events of the past months
+since the great European War began, it seems to me as if there had
+never been a period in Craig Kennedy's life more replete with
+thrilling adventures than this.
+
+In fact, scarcely had one mysterious event been straightened out
+from the tangled skein, when another, even more baffling, crowded
+on its very heels.
+
+As was to have been expected with us in America, not all of these
+remarkable experiences grew either directly or indirectly out of
+the war, but there were several that did, and they proved to be
+only the beginning of a succession of events which kept me busy
+chronicling for the Star the exploits of my capable and versatile
+friend.
+
+Altogether, this period of the war was, I am sure, quite the most
+exciting of the many series of episodes through which Craig has
+been called upon to go. Yet he seemed to meet each situation as it
+arose with a fresh mind, which was amazing even to me who have
+known him so long and so intimately.
+
+As was naturally to be supposed, also, at such a time, it was not
+long before Craig found himself entangled in the marvelous spy
+system of the warring European nations. These systems revealed
+their devious and dark ways, ramifying as they did tentacle-like
+even across the ocean in their efforts to gain their ends in
+neutral America. Not only so, but, as I shall some day endeavor to
+show later, when the ban of silence imposed by neutrality is
+raised after the war, many of the horrors of the war were brought
+home intimately to us.
+
+I have, after mature consideration, decided that even at present
+nothing but good can come from the publication at least of some
+part of the strange series of adventures through which Kennedy and
+I have just gone, especially those which might, if we had not
+succeeded, have caused most important changes in current history.
+As for the other adventures, no question can be raised about the
+propriety of their publication.
+
+At any rate, it came about that early in August, when the war
+cloud was just beginning to loom blackest, Kennedy was
+unexpectedly called into one of the strangest, most dangerous
+situations in which his peculiar and perilous profession had ever
+involved him.
+
+
+
+
+CHAPTER I
+
+THE WAR TERROR
+
+
+"I must see Professor Kennedy--where is he?--I must see him, for
+God's sake!"
+
+I was almost carried off my feet by the inrush of a wild-eyed
+girl, seemingly half crazed with excitement, as she cried out
+Craig's name.
+
+Startled by my own involuntary exclamation of surprise which
+followed the vision that shot past me as I opened our door in
+response to a sudden, sharp series of pushes at the buzzer,
+Kennedy bounded swiftly toward me, and the girl almost flung
+herself upon him.
+
+"Why, Miss--er--Miss--my dear young lady--what's the matter?" he
+stammered, catching her by the arm gently.
+
+As Kennedy forced our strange visitor into a chair, I observed
+that she was all a-tremble. Her teeth fairly chattered.
+Alternately her nervous, peaceless hands clutched at an imaginary
+something in the air, as if for support, then, finding none, she
+would let her wrists fall supine, while she gazed about with
+quivering lips and wild, restless eyes. Plainly, there was
+something she feared. She was almost over the verge of hysteria.
+
+She was a striking girl, of medium height and slender form, but it
+was her face that fascinated me, with its delicately molded
+features, intense unfathomable eyes of dark brown, and lips that
+showed her idealistic, high-strung temperament.
+
+"Please," he soothed, "get yourself together, please--try! What is
+the matter?"
+
+She looked about, as if she feared that the very walls had eyes
+and ears. Yet there seemed to be something bursting from her lips
+that she could not restrain.
+
+"My life," she cried wildly, "my life is at stake. Oh--help me,
+help me! Unless I commit a murder to-night, I shall be killed
+myself!"
+
+The words sounded so doubly strange from a girl of her evident
+refinement that I watched her narrowly, not sure yet but that we
+had a plain case of insanity to deal with.
+
+"A murder?" repeated Kennedy incredulously. "YOU commit a murder?"
+
+Her eyes rested on him, as if fascinated, but she did not flinch
+as she replied desperately, "Yes--Baron Kreiger--you know, the
+German diplomat and financier, who is in America raising money and
+arousing sympathy with his country."
+
+"Baron Kreiger!" exclaimed Kennedy in surprise, looking at her
+more keenly.
+
+We had not met the Baron, but we had heard much about him, young,
+handsome, of an old family, trusted already in spite of his youth
+by many of the more advanced of old world financial and political
+leaders, one who had made a most favorable impression on
+democratic America at a time when such impressions were valuable.
+
+Glancing from one of us to the other, she seemed suddenly, with a
+great effort, to recollect herself, for she reached into her
+chatelaine and pulled out a card from a case.
+
+It read simply, "Miss Paula Lowe."
+
+"Yes," she replied, more calmly now to Kennedy's repetition of the
+Baron's name, "you see, I belong to a secret group." She appeared
+to hesitate, then suddenly added, "I am an anarchist."
+
+She watched the effect of her confession and, finding the look on
+Kennedy's face encouraging rather than shocked, went on
+breathlessly: "We are fighting war with war--this iron-bound
+organization of men and women. We have pledged ourselves to
+exterminate all kings, emperors and rulers, ministers of war,
+generals--but first of all the financiers who lend money that
+makes war possible."
+
+She paused, her eyes gleaming momentarily with something like the
+militant enthusiasm that must have enlisted her in the paradoxical
+war against war.
+
+"We are at least going to make another war impossible!" she
+exclaimed, for the moment evidently forgetting herself.
+
+"And your plan?" prompted Kennedy, in the most matter-of-fact
+manner, as though he were discussing an ordinary campaign for
+social betterment. "How were you to--reach the Baron?"
+
+"We had a drawing," she answered with amazing calmness, as if the
+mere telling relieved her pent-up feelings. "Another woman and I
+were chosen. We knew the Baron's weakness for a pretty face. We
+planned to become acquainted with him--lure him on."
+
+Her voice trailed off, as if, the first burst of confidence over,
+she felt something that would lock her secret tighter in her
+breast.
+
+A moment later she resumed, now talking rapidly, disconnectedly,
+giving Kennedy no chance to interrupt or guide the conversation.
+
+"You don't know, Professor Kennedy," she began again, "but there
+are similar groups to ours in European countries and the plan is
+to strike terror and consternation everywhere in the world at
+once. Why, at our headquarters there have been drawn up plans and
+agreements with other groups and there are set down the time,
+place, and manner of all the--the removals."
+
+Momentarily she seemed to be carried away by something like the
+fanaticism of the fervor which had at first captured her, even
+still held her as she recited her incredible story.
+
+"Oh, can't you understand?" she went on, as if to justify herself.
+"The increase in armies, the frightful implements of slaughter,
+the total failure of the peace propaganda--they have all defied
+civilization!
+
+"And then, too, the old, red-blooded emotions of battle have all
+been eliminated by the mechanical conditions of modern warfare in
+which men and women are just so many units, automata. Don't you
+see? To fight war with its own weapons--that has become the only
+last resort."
+
+Her eager, flushed face betrayed the enthusiasm which had once
+carried her into the "Group," as she called it. I wondered what
+had brought her now to us.
+
+"We are no longer making war against man," she cried. "We are
+making war against picric acid and electric wires!"
+
+I confess that I could not help thinking that there was no doubt
+that to a certain type of mind the reasoning might appeal most
+strongly.
+
+"And you would do it in war time, too?" asked Kennedy quickly.
+
+She was ready with an answer. "King George of Greece was killed at
+the head of his troops. Remember Nazim Pasha, too. Such people are
+easily reached in time of peace and in time of war, also, by
+sympathizers on their own side. That's it, you see--we have
+followers of all nationalities."
+
+She stopped, her burst of enthusiasm spent. A moment later she
+leaned forward, her clean-cut profile showing her more earnest
+than before. "But, oh, Professor Kennedy," she added, "it is
+working itself out to be more terrible than war itself!"
+
+"Have any of the plans been carried out yet?" asked Craig, I
+thought a little superciliously, for there had certainly been no
+such wholesale assassination yet as she had hinted at.
+
+She seemed to catch her breath. "Yes," she murmured, then checked
+herself as if in fear of saying too much. "That is, I--I think
+so."
+
+I wondered if she were concealing something, perhaps had already
+had a hand in some such enterprise and it had frightened her.
+
+Kennedy leaned forward, observing the girl's discomfiture. "Miss
+Lowe," he said, catching her eye and holding it almost
+hypnotically, "why have you come to see me?"
+
+The question, pointblank, seemed to startle her. Evidently she had
+thought to tell only as little as necessary, and in her own way.
+She gave a little nervous laugh, as if to pass it off. But
+Kennedy's eyes conquered.
+
+"Oh, can't you understand yet?" she exclaimed, rising passionately
+and throwing out her arms in appeal. "I was carried away with my
+hatred of war. I hate it yet. But now--the sudden realization of
+what this compact all means has--well, caused something in me to--
+to snap. I don't care what oath I have taken. Oh, Professor
+Kennedy, you--you must save him!"
+
+I looked up at her quickly. What did she mean? At first she had
+come to be saved herself. "You must save him!" she implored.
+
+Our door buzzer sounded.
+
+She gazed about with a hunted look, as if she felt that some one
+had even now pursued her and found out.
+
+"What shall I do?" she whispered. "Where shall I go?"
+
+"Quick--in here. No one will know," urged Kennedy, opening the
+door to his room. He paused for an instant, hurriedly. "Tell me--
+have you and this other woman met the Baron yet? How far has it
+gone?"
+
+The look she gave him was peculiar. I could not fathom what was
+going on in her mind. But there was no hesitation about her
+answer. "Yes," she replied, "I--we have met him. He is to come
+back to New York from Washington to-day--this afternoon--to
+arrange a private loan of five million dollars with some bankers
+secretly. We were to see him to-night--a quiet dinner, after an
+automobile ride up the Hudson--"
+
+"Both of you?" interrupted Craig.
+
+"Yes--that--that other woman and myself," she repeated, with a
+peculiar catch in her voice. "To-night was the time fixed in the
+drawing for the--"
+
+The word stuck in her throat. Kennedy understood. "Yes, yes," he
+encouraged, "but who is the other woman?"
+
+Before she could reply, the buzzer had sounded again and she had
+retreated from the door. Quickly Kennedy closed it and opened the
+outside door.
+
+It was our old friend Burke of the Secret Service.
+
+Without a word of greeting, a hasty glance seemed to assure him
+that Kennedy and I were alone. He closed the door himself, and,
+instead of sitting down, came close to Craig.
+
+"Kennedy," he blurted out in a tone of suppressed excitement, "can
+I trust you to keep a big secret?"
+
+Craig looked at him reproachfully, but said nothing.
+
+"I beg your pardon--a thousand times," hastened Burke. "I was so
+excited, I wasn't thinking--"
+
+"Once is enough, Burke," laughed Kennedy, his good nature restored
+at Burke's crestfallen appearance.
+
+"Well, you see," went on the Secret Service man, "this thing is so
+very important that--well, I forgot."
+
+He sat down and hitched his chair close to us, as he went on in a
+lowered, almost awestruck tone.
+
+"Kennedy," he whispered, "I'm on the trail, I think, of something
+growing out of these terrible conditions in Europe that will tax
+the best in the Secret Service. Think of it, man. There's an
+organization, right here in this city, a sort of assassin's club,
+as it were, aimed at all the powerful men the world over. Why, the
+most refined and intellectual reformers have joined with the most
+red-handed anarchists and--"
+
+"Sh! not so loud," cautioned Craig. "I think I have one of them in
+the next room. Have they done anything yet to the Baron?"
+
+It was Burke's turn now to look from one to the other of us in
+unfeigned surprise that we should already know something of his
+secret.
+
+"The Baron?" he repeated, lowering his voice. "What Baron?"
+
+It was evident that Burke knew nothing, at least of this new plot
+which Miss Lowe had indicated. Kennedy beckoned him over to the
+window furthest from the door to his own room.
+
+"What have you discovered?" he asked, forestalling Burke in the
+questioning. "What has happened?"
+
+"You haven't heard, then?" replied Burke.
+
+Kennedy nodded negatively.
+
+"Fortescue, the American inventor of fortescite, the new
+explosive, died very strangely this morning."
+
+"Yes," encouraged Kennedy, as Burke came to a full stop to observe
+the effect of the information.
+
+"Most incomprehensible, too," he pursued. "No cause, apparently.
+But it might have been overlooked, perhaps, except for one thing.
+It wasn't known generally, but Fortescue had just perfected a
+successful electro-magnetic gun--powderless, smokeless, flashless,
+noiseless and of tremendous power. To-morrow he was to have signed
+the contract to sell it to England. This morning he is found dead
+and the final plans of the gun are gone!"
+
+Kennedy and Burke were standing mutely looking at each other.
+
+"Who is in the next room?" whispered Burke hoarsely, recollecting
+Kennedy's caution of silence.
+
+Kennedy did not reply immediately. He was evidently much excited
+by Burke's news of the wonderful electro-magnetic gun.
+
+"Burke," he exclaimed suddenly, "let's join forces. I think we are
+both on the trail of a world-wide conspiracy--a sort of murder
+syndicate to wipe out war!"
+
+Burke's only reply was a low whistle that involuntarily escaped
+him as he reached over and grasped Craig's hand, which to him
+represented the sealing of the compact.
+
+As for me, I could not restrain a mental shudder at the power that
+their first murder had evidently placed in the hands of the
+anarchists, if they indeed had the electro-magnetic gun which
+inventors had been seeking for generations. What might they not do
+with it--perhaps even use it themselves and turn the latest
+invention against society itself!
+
+Hastily Craig gave a whispered account of our strange visit from
+Miss Lowe, while Burke listened, open-mouthed.
+
+He had scarcely finished when he reached for the telephone and
+asked for long distance.
+
+"Is this the German embassy in Washington?" asked Craig a few
+moments later when he got his number. "This is Craig Kennedy, in
+New York. The United States Secret Service will vouch for me--
+mention to them Mr. Burke of their New York office who is here
+with me now. I understand that Baron Kreiger is leaving for New
+York to meet some bankers this afternoon. He must not do so. He is
+in the gravest danger if he--What? He left last night at midnight
+and is already here?"
+
+Kennedy turned to us blankly.
+
+The door to his room opened suddenly.
+
+There stood Miss Lowe, gazing wild-eyed at us. Evidently her
+supernervous condition had heightened the keenness of her senses.
+She had heard what we were saying. I tried to read her face. It
+was not fear that I saw there. It was rage; it was jealousy.
+
+"The traitress--it is Marie!" she shrieked.
+
+For a moment, obtusely, I did not understand.
+
+"She has made a secret appointment with him," she cried.
+
+At last I saw the truth. Paula Lowe had fallen in love with the
+man she had sworn to kill!
+
+
+
+
+CHAPTER II
+
+THE ELECTRO-MAGNETIC GUN
+
+
+"What shall we do?" demanded Burke, instantly taking in the
+dangerous situation that the Baron's sudden change of plans had
+opened up.
+
+"Call O'Connor," I suggested, thinking of the police bureau of
+missing persons, and reaching for the telephone.
+
+"No, no!" almost shouted Craig, seizing my arm. "The police will
+inevitably spoil it all. No, we must play a lone hand in this if
+we are to work it out. How was Fortescue discovered, Burke?"
+
+"Sitting in a chair in his laboratory. He must have been there all
+night. There wasn't a mark on him, not a sign of violence, yet his
+face was terribly drawn as though he were gasping for breath or
+his heart had suddenly failed him. So far, I believe, the coroner
+has no clue and isn't advertising the case."
+
+"Take me there, then," decided Craig quickly. "Walter, I must
+trust Miss Lowe to you on the journey. We must all go. That must
+be our starting point, if we are to run this thing down."
+
+I caught his significant look to me and interpreted it to mean
+that he wanted me to watch Miss Lowe especially. I gathered that
+taking her was in the nature of a third degree and as a result he
+expected to derive some information from her. Her face was pale
+and drawn as we four piled into a taxicab for a quick run downtown
+to the laboratory of Fortescue from which Burke had come directly
+to us with his story.
+
+"What do you know of these anarchists?" asked Kennedy of Burke as
+we sped along. "Why do you suspect them?"
+
+It was evident that he was discussing the case so that Paula could
+overhear, for a purpose.
+
+"Why, we received a tip from abroad--I won't say where," replied
+Burke guardedly, taking his cue. "They call themselves the
+'Group,' I believe, which is a common enough term among
+anarchists. It seems they are composed of terrorists of all
+nations."
+
+"The leader?" inquired Kennedy, leading him on.
+
+"There is one, I believe, a little florid, stout German. I think
+he is a paranoiac who believes there has fallen on himself a
+divine mission to end all warfare. Quite likely he is one of those
+who have fled to America to avoid military service. Perhaps, why
+certainly, you must know him--Annenberg, an instructor in
+economics now at the University?"
+
+Craig nodded and raised his eyebrows in mild surprise. We had
+indeed heard of Annenberg and some of his radical theories which
+had sometimes quite alarmed the conservative faculty. I felt that
+this was getting pretty close home to us now.
+
+"How about Mrs. Annenberg?" Craig asked, recalling the clever
+young wife of the middle-aged professor.
+
+At the mere mention of the name, I felt a sort of start in Miss
+Lowe, who was seated next to me in the taxicab. She had quickly
+recovered herself, but not before I saw that Kennedy's plan of
+breaking down the last barrier of her reserve was working.
+
+"She is one of them, too," Burke nodded. "I have had my men out
+shadowing them and their friends. They tell me that the Annenbergs
+hold salons--I suppose you would call them that--attended by
+numbers of men and women of high social and intellectual position
+who dabble in radicalism and all sorts of things." "Who are the
+other leaders?" asked Craig. "Have you any idea?"
+
+"Some idea," returned Burke. "There seems to be a Frenchman, a
+tall, wiry man of forty-five or fifty with a black mustache which
+once had a military twist. There are a couple of Englishmen. Then
+there are five or six Americans who seem to be active. One, I
+believe, is a young woman."
+
+Kennedy checked him with a covert glance, but did not betray by a
+movement of a muscle to Miss Lowe that either Burke or himself
+suspected her of being the young woman in question.
+
+"There are three Russians," continued Burke, "all of whom have
+escaped from Siberia. Then there is at least one Austrian, a
+Spaniard from the Ferrer school, and Tomasso and Enrico, two
+Italians, rather heavily built, swarthy, bearded. They look the
+part. Of course there are others. But these in the main, I think,
+compose what might be called 'the inner circle' of the 'Group.'"
+
+It was indeed an alarming, terrifying revelation, as we began to
+realize that Miss Lowe had undoubtedly been telling the truth. Not
+alone was there this American group, evidently, but all over
+Europe the lines of the conspiracy had apparently spread. It was
+not a casual gathering of ordinary malcontents. It went deeper
+than that. It included many who in their disgust at war secretly
+were not unwilling to wink at violence to end the curse. I could
+not but reflect on the dangerous ground on which most of them were
+treading, shaking the basis of all civilization in order to cut
+out one modern excrescence.
+
+The big fact to us, just at present, was that this group had made
+America its headquarters, that plans had been studiously matured
+and even reduced to writing, if Paula were to be believed.
+Everything had been carefully staged for a great simultaneous blow
+or series of blows that would rouse the whole world.
+
+As I watched I could not escape observing that Miss Lowe followed
+Burke furtively now, as though he had some uncanny power.
+
+Fortescue's laboratory was in an old building on a side street
+several blocks from the main thoroughfares of Manhattan. He had
+evidently chosen it, partly because of its very inaccessibility in
+order to secure the quiet necessary for his work.
+
+"If he had any visitors last night," commented Kennedy when our
+cab at last pulled up before the place, "they might have come and
+gone unnoticed."
+
+We entered. Nothing had been disturbed in the laboratory by the
+coroner and Kennedy was able to gain a complete idea of the case
+rapidly, almost as well as if we had been called in immediately.
+
+Fortescue's body, it seemed, had been discovered sprawled out in a
+big armchair, as Burke had said, by one of his assistants only a
+few hours before when he had come to the laboratory in the morning
+to open it. Evidently he had been there undisturbed all night,
+keeping a gruesome vigil over his looted treasure house.
+
+As we gleaned the meager facts, it became more evident that
+whoever had perpetrated the crime must have had the diabolical
+cunning to do it in some ordinary way that aroused no suspicion on
+the part of the victim, for there was no sign of any violence
+anywhere.
+
+As we entered the laboratory, I noted an involuntary shudder on
+the part of Paula Lowe, but, as far as I knew, it was no more than
+might have been felt by anyone under the circumstances.
+
+Fortescue's body had been removed from the chair in which it had
+been found and lay on a couch at the other end of the room,
+covered merely by a sheet. Otherwise, everything, even the
+armchair, was undisturbed.
+
+Kennedy pulled back a corner of the sheet, disclosing the face,
+contorted and of a peculiar, purplish hue from the congested blood
+vessels. He bent over and I did so, too. There was an unmistakable
+odor of tobacco on him. A moment Kennedy studied the face before
+us, then slowly replaced the sheet.
+
+Miss Lowe had paused just inside the door and seemed resolutely
+bound not to look at anything. Kennedy meanwhile had begun a most
+minute search of the table and floor of the laboratory near the
+spot where the armchair had been sitting.
+
+In my effort to glean what I could from her actions and
+expressions I did not notice that Craig had dropped to his knees
+and was peering into the shadow under the laboratory table. When
+at last he rose and straightened himself up, however, I saw that
+he was holding in the palm of his hand a half-smoked, gold-tipped
+cigarette, which had evidently fallen on the floor beneath the
+table where it had burned itself out, leaving a blackened mark on
+the wood.
+
+An instant afterward he picked out from the pile of articles found
+in Fortescue's pockets and lying on another table a silver
+cigarette case. He snapped it open. Fortescue's cigarettes, of
+which there were perhaps a half dozen in the case, were cork-
+tipped.
+
+Some one had evidently visited the inventor the night before, had
+apparently offered him a cigarette, for there were any number of
+the cork-tipped stubs lying about. Who was it? I caught Paula
+looking with fascinated gaze at the gold-tipped stub, as Kennedy
+carefully folded it up in a piece of paper and deposited it in his
+pocket. Did she know something about the case, I wondered?
+
+Without a word, Kennedy seemed to take in the scant furniture of
+the laboratory at a glance and a quick step or two brought him
+before a steel filing cabinet. One drawer, which had not been
+closed as tightly as the rest, projected a bit. On its face was a
+little typewritten card bearing the inscription: "E-M GUN."
+
+He pulled the drawer open and glanced over the data in it.
+
+"Just what is an electro-magnetic gun?" I asked, interpreting the
+initials on the drawer.
+
+"Well," he explained as he turned over the notes and sketches,
+"the primary principle involved in the construction of such a gun
+consists in impelling the projectile by the magnetic action of a
+solenoid, the sectional coils or helices of which are supplied
+with current through devices actuated by the projectile itself. In
+other words, the sections of helices of the solenoid produce an
+accelerated motion of the projectile by acting successively on it,
+after a principle involved in the construction of electro-magnetic
+rock drills and dispatch tubes.
+
+"All projectiles used in this gun of Fortescue's evidently must
+have magnetic properties and projectiles of iron or containing
+large portions of iron are necessary. You see, many coils are
+wound around the barrel of the gun. As the projectile starts it
+does so under the attraction of those coils ahead which the
+current makes temporary magnets. It automatically cuts off the
+current from those coils that it passes, allowing those further on
+only to attract it, and preventing those behind from pulling it
+back."
+
+He paused to study the scraps of plans. "Fortescue had evidently
+also worked out a way of changing the poles of the coils as the
+projectile passed, causing them then to repel the projectile,
+which must have added to its velocity. He seems to have overcome
+the practical difficulty that in order to obtain service
+velocities with service projectiles an enormous number of windings
+and a tremendously long barrel are necessary as well as an
+abnormally heavy current beyond the safe carrying capacity of the
+solenoid which would raise the temperature to a point that would
+destroy the coils."
+
+He continued turning over the prints and notes in the drawer. When
+he finished, he looked up at us with an expression that indicated
+that he had merely satisfied himself of something he had already
+suspected.
+
+"You were right, Burke," he said. "The final plans are gone."
+
+Burke, who, in the meantime, had been telephoning about the city
+in a vain effort to locate Baron Kreiger, both at such banking
+offices in Wall Street as he might be likely to visit and at some
+of the hotels most frequented by foreigners, merely nodded. He was
+evidently at a loss completely how to proceed.
+
+In fact, there seemed to be innumerable problems--to warn Baron
+Kreiger, to get the list of the assassinations, to guard Miss Lowe
+against falling into the hands of her anarchist friends again, to
+find the murderer of Fortescue, to prevent the use of the electro-
+magnetic gun, and, if possible, to seize the anarchists before
+they had a chance to carry further their plans.
+
+"There is nothing more that we can do here," remarked Craig
+briskly, betraying no sign of hesitation. "I think the best thing
+we can do is to go to my own laboratory. There at least there is
+something I must investigate sooner or later."
+
+No one offering either a suggestion or an objection, we four again
+entered our cab. It was quite noticeable now that the visit had
+shaken Paula Lowe, but Kennedy still studiously refrained from
+questioning her, trusting that what she had seen and heard,
+especially Burke's report as to Baron Kreiger, would have its
+effect.
+
+Like everyone visiting Craig's laboratory for the first time, Miss
+Lowe seemed to feel the spell of the innumerable strange and
+uncanny instruments which he had gathered about him in his
+scientific warfare against crime. I could see that she was
+becoming more and more nervous, perhaps fearing even that in some
+incomprehensible way he might read her own thoughts. Yet one thing
+I did not detect. She showed no disposition to turn back on the
+course on which she had entered by coming to us in the first
+place.
+
+Kennedy was quickly and deftly testing the stub of the little
+thin, gold-tipped cigarette.
+
+"Excessive smoking," he remarked casually, "causes neuroses of the
+heart and tobacco has a specific affinity for the coronary
+arteries as well as a tremendous effect on the vagus nerve. But I
+don't think this was any ordinary smoke."
+
+He had finished his tests and a quiet smile of satisfaction
+flitted momentarily over his face. We had been watching him
+anxiously, wondering what he had found.
+
+As he looked up he remarked to us, with his eyes fixed on Miss
+Lowe, "That was a ladies' cigarette. Did you notice the size?
+There has been a woman in this case--presumably."
+
+The girl, suddenly transformed by the rapid-fire succession of
+discoveries, stood before us like a specter.
+
+"The 'Group,' as anarchists call it," pursued Craig, "is the
+loosest sort of organization conceivable, I believe, with no set
+membership, no officers, no laws--just a place of meeting with no
+fixity, where the comrades get together. Could you get us into the
+inner circle, Miss Lowe?"
+
+Her only answer was a little suppressed scream. Kennedy had asked
+the question merely for its effect, for it was only too evident
+that there was no time, even if she could have managed it, for us
+to play the "stool pigeon."
+
+Kennedy, who had been clearing up the materials he had used in the
+analysis of the cigarette, wheeled about suddenly. "Where is the
+headquarters of the inner circle?" he shot out.
+
+Miss Lowe hesitated. That had evidently been one of the things she
+had determined not to divulge.
+
+"Tell me," insisted Kennedy. "You must!"
+
+If it had been Burke's bulldozing she would never have yielded.
+But as she looked into Kennedy's eyes she read there that he had
+long since fathomed the secret of her wildly beating heart, that
+if she would accomplish the purpose of saving the Baron she must
+stop at nothing.
+
+"At--Maplehurst," she answered in a low tone, dropping her eyes
+from his penetrating gaze, "Professor Annenberg's home--out on
+Long Island."
+
+"We must act swiftly if we are to succeed," considered Kennedy,
+his tone betraying rather sympathy with than triumph over the
+wretched girl who had at last cast everything in the balance to
+outweigh the terrible situation into which she had been drawn. "To
+send Miss Lowe for that fatal list of assassinations is to send
+her either back into the power of this murderous group and let
+them know that she has told us, or perhaps to involve her again in
+the completion of their plans."
+
+She sank back into a chair in complete nervous and physical
+collapse, covering her face with her hands at the realization that
+in her new-found passion to save the Baron she had bared her
+sensitive soul for the dissection of three men whom she had never
+seen before.
+
+"We must have that list," pursued Kennedy decisively. "We must
+visit Annenberg's headquarters."
+
+"And I?" she asked, trembling now with genuine fear at the thought
+that he might ask her to accompany us as he had on our visit to
+Fortescue's laboratory that morning.
+
+"Miss Lowe," said Kennedy, bending over her, "you have gone too
+far now ever to turn back. You are not equal to the trip. Would
+you like to remain here? No one will suspect. Here at least you
+will be safe until we return."
+
+Her answer was a mute expression of thanks and confidence.
+
+
+
+
+CHAPTER III
+
+THE MURDER SYNDICATE
+
+
+Quickly now Craig completed his arrangements for the visit to the
+headquarters of the real anarchist leader. Burke telephoned for a
+high-powered car, while Miss Lowe told frankly of the habits of
+Annenberg and the chances of finding his place unguarded, which
+were good in the daytime. Kennedy's only equipment for the
+excursion consisted in a small package which he took from a
+cabinet at the end of the room, and, with a parting reassurance to
+Paula Lowe, we were soon speeding over the bridge to the borough
+across the river.
+
+We realized that it might prove a desperate undertaking, but the
+crisis was such that it called for any risk.
+
+Our quest took us to a rather dilapidated old house on the
+outskirts of the little Long Island town. The house stood alone,
+not far from the tracks of a trolley that ran at infrequent
+intervals. Even a hasty reconnoitering showed that to stop our
+motor at even a reasonable distance from it was in itself to
+arouse suspicion.
+
+Although the house seemed deserted, Craig took no chances, but
+directed the car to turn at the next crossroad and then run back
+along a road back of and parallel to that on which Annenberg's was
+situated. It was perhaps a quarter of a mile away, across an open
+field, that we stopped and ran the car up along the side of the
+road in some bushes. Annenberg's was plainly visible and it was
+not at all likely that anyone there would suspect trouble from
+that quarter.
+
+A hasty conference with Burke followed, in which Kennedy unwrapped
+his small package, leaving part of its contents with him, and
+adding careful instructions.
+
+Then Kennedy and I retraced our steps down the road, across by the
+crossroad, and at last back to the mysterious house.
+
+To all appearance there had been no need of such excessive
+caution. Not a sound or motion greeted us as we entered the gate
+and made our way around to the rear of the house. The very
+isolation of the house was now our protection, for we had no
+inquisitive neighbors to watch us for the instant when Kennedy,
+with the dexterity of a yeggman, inserted his knife between the
+sashes of the kitchen window and turned the catch which admitted
+us.
+
+We made our way on cautious tiptoe through a dining room to a
+living room, and, finding nothing, proceeded upstairs. There was
+not a soul, apparently, in the house, nor in fact anything to
+indicate that it was different from most small suburban homes,
+until at last we mounted to the attic.
+
+It was finished off in one large room across the back of the house
+and two in front. As we opened the door to the larger room, we
+could only gaze about in surprise. This was the rendezvous, the
+arsenal, literary, explosive and toxicological of the "Group."
+Ranged on a table were all the materials for bomb-making, while in
+a cabinet I fancied there were poisons enough to decimate a city.
+
+On the walls were pictures, mostly newspaper prints, of the
+assassins of McKinley, of King Humbert, of the King of Greece, of
+King Carlos and others, interspersed with portraits of anarchist
+and anti-militarist leaders of all lands.
+
+Kennedy sniffed. Over all I, too, could catch the faint odor of
+stale tobacco. No time was to be lost, however, and while Craig
+set to work rapidly going through the contents of a desk in the
+corner, I glanced over the contents of a drawer of a heavy mission
+table.
+
+"Here's some of Annenberg's literature," I remarked, coming across
+a small pile of manuscript, entitled "The Human Slaughter House."
+
+"Read it," panted Kennedy, seeing that I had about completed my
+part of the job. "It may give a clue."
+
+Hastily I scanned the mad, frantic indictment of war, while Craig
+continued in his search:
+
+"I see wild beasts all around me, distorted unnaturally, in a life
+and death struggle, with bloodshot eyes, with foaming, gnashing
+mouths. They attack and kill one another and try to mangle each
+other. I leap to my feet. I race out into the night and tread on
+quaking flesh, step on hard heads, and stumble over weapons and
+helmets. Something is clutching at my feet like hands, so that I
+race away like a hunted deer with the hounds at his heels--and
+ever over more bodies--breathless... out of one field into
+another. Horror is crooning over my head. Horror is crooning
+beneath my feet. And nothing but dying, mangled flesh!
+
+"Of a sudden I see nothing but blood before me. The heavens have
+opened and the red blood pours in through the windows. Blood wells
+up on an altar. The walls run blood from the ceiling to the floor
+and... a giant of blood stands before me. His beard and his hair
+drip blood. He seats himself on the altar and laughs from thick
+lips. The black executioner raises his sword and whirls it above
+my head. Another moment and my head will roll down on the floor.
+Another moment and the red jet will spurt from my neck.
+
+"Murderers! Murderers! None other than murderers!"
+
+I paused in the reading. "There's nothing here," I remarked,
+glancing over the curious document for a clue, but finding none.
+
+"Well," remarked Craig contemplatively, "one can at least easily
+understand how sensitive and imaginative people who have fallen
+under the influence of one who writes in that way can feel
+justified in killing those responsible for bringing such horrors
+on the human race. Hello--what's this?"
+
+He had discovered a false back of one of the drawers in the desk
+and had jimmied it open. On the top of innumerable papers lay a
+large linen envelope. On its face it bore in typewriting, just
+like the card on the drawer at Fortescue's, "E-M GUN."
+
+"It is the original envelope that contained the final plans of the
+electro-magnetic gun," he explained, opening it.
+
+The envelope was empty. We looked at each other a moment in
+silence. What had been done with the plans?
+
+Suddenly a bell rang, startling me beyond measure. It was,
+however, only the telephone, of which an extension reached up into
+the attic-arsenal. Some one, who did not know that we were there,
+was evidently calling up.
+
+Kennedy quickly unhooked the receiver with a hasty motion to me to
+be silent.
+
+"Hello," I heard him answer. "Yes, this is it."
+
+He had disguised his voice. I waited anxiously and watched his
+face to gather what response he received.
+
+"The deuce!" he exclaimed, with his hand over the transmitter so
+that his voice would not be heard at the other end of the line.
+
+"What's the matter?" I asked eagerly.
+
+"It was Mrs. Annenberg--I am sure. But she was too keen for me.
+She caught on. There must be some password or form of expression
+that they use, which we don't know, for she hung up the receiver
+almost as soon as she heard me."
+
+Kennedy waited a minute or so. Then he whistled into the
+transmitter. It was done apparently to see whether there was
+anyone listening. But there was no answer.
+
+"Operator, operator!" he called insistently, moving the hook up
+and down. "Yes, operator. Can you tell me what number that was
+which just called?"
+
+He waited impatiently.
+
+"Bleecker--7l80," he repeated after the girl. "Thank you.
+Information, please."
+
+Again we waited, as Craig tried to trace the call up.
+
+"What is the street address of Bleecker, 7180?" he asked. "Five
+hundred and one East Fifth--a tenement. Thank you."
+
+"A tenement?" I repeated blankly.
+
+"Yes," he cried, now for the first time excited. "Don't you begin
+to see the scheme? I'll wager that Baron Kreiger has been lured to
+New York to purchase the electro-magnetic gun which they have
+stolen from Fortescue and the British. That is the bait that is
+held out to him by the woman. Call up Miss Lowe at the laboratory
+and see if she knows the place."
+
+I gave central the number, while he fell to at the little secret
+drawer of the desk again. The grinding of the wheels of a passing
+trolley interfered somewhat with giving the number and I had to
+wait a moment.
+
+"Ah--Walter--here's the list!" almost shouted Kennedy, as he broke
+open a black-japanned dispatch box in the desk.
+
+I bent over it, as far as the slack of the telephone wire of the
+receiver at my ear would permit. Annenberg had worked with amazing
+care and neatness on the list, even going so far as to draw at the
+top, in black, a death's head. The rest of it was elaborately
+prepared in flaming red ink.
+
+Craig gasped to observe the list of world-famous men marked for
+destruction in London, Paris, Berlin, Rome, Vienna, St.
+Petersburg, and even in New York and Washington.
+
+"What is the date set?" I asked, still with my ear glued to the
+receiver.
+
+"To-night and to-morrow," he replied, stuffing the fateful sheet
+into his pocket.
+
+Rummaging about in the drawer of the table, I had come to a
+package of gold-tipped cigarettes which had interested me and I
+had left them out. Kennedy was now looking at them curiously.
+
+"What is to be the method, do you suppose?" I asked.
+
+"By a poison that is among the most powerful, approaching even
+cyanogen," he replied confidently, tapping the cigarettes. "Do you
+smell the odor in this room? What is it like?"
+
+"Stale tobacco," I replied.
+
+"Exactly--nicotine. Two or three drops on the mouth-end of a cigar
+or cigarette. The intended victim thinks it is only natural. But
+it is the purest form of the deadly alkaloid--fatal in a few
+minutes, too."
+
+He examined the thin little cigarettes more carefully. "Nicotine,"
+he went on, "was about the first alkaloid that was recovered from
+the body by chemical analysis in a homicide case. That is the
+penetrating, persistent odor you smelled at Fortescue's and also
+here. It's a very good poison--if you are not particular about
+being discovered. A pound of ordinary smoking tobacco contains
+from a half to an ounce of it. It is almost entirely consumed by
+combustion; otherwise a pipeful would be fatal. Of course they may
+have thought that investigators would believe that their victims
+were inveterate smokers. But even the worst tobacco fiend wouldn't
+show traces of the weed to such an extent."
+
+Miss Lowe answered at last and Kennedy took the telephone.
+
+"What is at five hundred and one East Fifth?" he asked.
+
+"A headquarters of the Group in the city," she answered. "Why?"
+
+"Well, I believe that the plans of that gun are there and that the
+Baron--"
+
+"You damned spies!" came a voice from behind us.
+
+Kennedy dropped the receiver, turning quickly, his automatic
+gleaming in his hand.
+
+There was just a glimpse of a man with glittering bright blue eyes
+that had an almost fiendish, baleful glare. An instant later the
+door which had so unexpectedly opened banged shut, we heard a key
+turn in the lock--and the man dropped to the floor before even
+Kennedy's automatic could test its ability to penetrate wood on a
+chance at hitting something the other side of it.
+
+We were prisoners!
+
+My mind worked automatically. At this very moment, perhaps, Baron
+Kreiger might be negotiating for the electro-magnetic gun. We had
+found out where he was, in all probability, but we were powerless
+to help him. I thought of Miss Lowe, and picked up the receiver
+which Kennedy had dropped.
+
+She did not answer. The wire had been cut. We were isolated!
+
+Kennedy had jumped to the window. I followed to restrain him,
+fearing that he had some mad scheme for climbing out. Instead,
+quickly he placed a peculiar arrangement, from the little package
+he had brought, holding it to his eye as if sighting it, his right
+hand grasping a handle as one holds a stereoscope. A moment later,
+as I examined it more closely, I saw that instead of looking at
+anything he had before him a small parabolic mirror turned away
+from him.
+
+His finger pressed alternately on a button on the handle and I
+could see that there flashed in the little mirror a minute
+incandescent lamp which seemed to have a special filament
+arrangement.
+
+The glaring sun was streaming in at the window and I wondered what
+could possibly be accomplished by the little light in competition
+with the sun itself.
+
+"Signaling by electric light in the daytime may sound to you
+ridiculous," explained Craig, still industriously flashing the
+light, "but this arrangement with Professor Donath's signal mirror
+makes it possible, all right.
+
+"I hadn't expected this, but I thought I might want to communicate
+with Burke quickly. You see, I sight the lamp and then press the
+button which causes the light in the mirror to flash. It seems a
+paradox that a light like this can be seen from a distance of even
+five miles and yet be invisible to one for whom it was not
+intended, but it is so. I use the ordinary Morse code--two seconds
+for a dot, six for a dash with a four-second interval."
+
+"What message did you send?" I asked.
+
+"I told him that Baron Kreiger was at five hundred and one East
+Fifth, probably; to get the secret service office in New York by
+wire and have them raid the place, then to come and rescue us.
+That was Annenberg. He must have come up by that trolley we heard
+passing just before."
+
+The minutes seemed ages as we waited for Burke to start the
+machinery of the raid and then come for us.
+
+"No--you can't have a cigarette--and if I had a pair of bracelets
+with me, I'd search you myself," we heard a welcome voice growl
+outside the door a few minutes later. "Look in that other pocket,
+Tom."
+
+The lock grated back and there stood Burke holding in a grip of
+steel the undersized Annenberg, while the chauffeur who had driven
+our car swung open the door.
+
+"I'd have been up sooner," apologized Burke, giving the anarchist
+an extra twist just to let him know that he was at last in the
+hands of the law, "only I figured that this fellow couldn't have
+got far away in this God-forsaken Ducktown and I might as well
+pick him up while I had a chance. That's a great little instrument
+of yours, Kennedy. I got you, fine."
+
+Annenberg, seeing we were now four to one, concluded that
+discretion was the better part of valor and ceased to struggle,
+though now and then I could see he glanced at Kennedy out of the
+corner of his eye. To every question he maintained a stolid
+silence.
+
+A few minutes later, with the arch anarchist safely pinioned
+between us, we were speeding back toward New York, laying plans
+for Burke to dispatch warnings abroad to those whose names
+appeared on the fatal list, and at the same time to round up as
+many of the conspirators as possible in America.
+
+As for Kennedy, his main interest now lay in Baron Kreiger and
+Paula. While she had been driven frantic by the outcome of the
+terrible pact into which she had been drawn, some one,
+undoubtedly, had been trying to sell Baron Kreiger the gun that
+had been stolen from the American inventor. Once they had his
+money and he had received the plans of the gun, a fatal cigarette
+would be smoked. Could we prevent it?
+
+On we tore back to the city, across the bridge and down through
+the canyons of East Side streets.
+
+At last we pulled up before the tenement at five hundred and one.
+As we did so, one of Burke's men jumped out of the doorway.
+
+"Are we in time?" shouted Burke.
+
+"It's an awful mix-up," returned the man. "I can't make anything
+out of it, so I ordered 'em all held here till you came."
+
+We pushed past without a word of criticism of his wonderful
+acumen.
+
+On the top floor we came upon a young man, bending over the form
+of a girl who had fainted. On the floor of the middle of the room
+was a mass of charred papers which had evidently burned a hole in
+the carpet before they had been stamped out. Near by was an
+unlighted cigarette, crushed flat on the floor.
+
+"How is she?" asked Kennedy anxiously of the young man, as he
+dropped down on the other side of the girl.
+
+It was Paula. She had fainted, but was just now coming out of the
+borderland of unconsciousness.
+
+"Was I in time? Had he smoked it?" she moaned weakly, as there
+swam before her eyes, evidently, a hazy vision of our faces.
+
+Kennedy turned to the young man.
+
+"Baron Kreiger, I presume?" he inquired.
+
+The young man nodded.
+
+"Burke of the Secret Service," introduced Craig, indicating our
+friend. "My name is Kennedy. Tell what happened."
+
+"I had just concluded a transaction," returned Kreiger in good but
+carefully guarded English. "Suddenly the door burst open. She
+seized these papers and dashed a cigarette out of my hands. The
+next instant she had touched a match to them and had fallen in a
+faint almost in the blaze. Strangest experience I ever had in my
+life. Then all these other fellows came bursting in--said they
+were Secret Service men, too."
+
+Kennedy had no time to reply, for a cry from Annenberg directed
+our attention to the next room where on a couch lay a figure all
+huddled up.
+
+As we looked we saw it was a woman, her head sweating profusely,
+and her hands cold and clammy. There was a strange twitching of
+the muscles of the face, the pupils of her eyes were widely
+dilated, her pulse weak and irregular. Evidently her circulation
+had failed so that it responded only feebly to stimulants, for her
+respiration was slow and labored, with loud inspiratory gasps.
+
+Annenberg had burst with superhuman strength from Burke's grasp
+and was kneeling by the side of his wife's deathbed.
+
+"It--was all Paula's fault--" gasped the woman. "I--knew I had
+better--carry it through--like the Fortescue visit--alone."
+
+I felt a sense of reassurance at the words. At least my suspicions
+had been unfounded. Paula was innocent of the murder of Fortescue.
+
+"Severe, acute nicotine poisoning," remarked Kennedy, as he
+rejoined us a moment later. "There is nothing we can do--now."
+
+Paula moved at the words, as though they had awakened a new energy
+in her. With a supreme effort she raised herself.
+
+"Then I--I failed?" she cried, catching sight of Kennedy.
+
+"No, Miss Lowe," he answered gently. "You won. The plans of the
+terrible gun are destroyed. The Baron is safe. Mrs. Annenberg has
+herself smoked one of the fatal cigarettes intended for him."
+
+Kreiger looked at us, uncomprehending. Kennedy picked up the
+crushed, unlighted cigarette and laid it in the palm of his hand
+beside another, half smoked, which he had found beside Mrs.
+Annenberg.
+
+"They are deadly," he said simply to Kreiger. "A few drops of pure
+nicotine hidden by that pretty gilt tip would have accomplished
+all that the bitterest anarchist could desire."
+
+All at once Kreiger seemed to realize what he had escaped so
+narrowly. He turned toward Paula. The revulsion of her feelings at
+seeing him safe was too much for her shattered nerves.
+
+With a faint little cry, she tottered.
+
+Before any of us could reach her, he had caught her in his arms
+and imprinted a warm kiss on the insensible lips.
+
+"Some water--quick!" he cried, still holding her close.
+
+
+
+
+CHAPTER IV
+
+THE AIR PIRATE
+
+
+Rounding up the "Group" took several days, and it proved to be a
+great story for the Star. I was pretty fagged when it was all
+over, but there was a great deal of satisfaction in knowing that
+we had frustrated one of the most daring anarchist plots of recent
+years.
+
+"Can you arrange to spend the week-end with me at Stuyvesant
+Verplanck's at Bluffwood?" asked Kennedy over the telephone, the
+afternoon that I had completed my work on the newspaper of undoing
+what Annenberg and the rest had attempted.
+
+"How long since society took you up?" I asked airily, adding, "Is
+it a large house party you are getting up?"
+
+"You have heard of the so-called 'phantom bandit' of Bluffwood,
+haven't you?" he returned rather brusquely, as though there was no
+time now for bantering.
+
+I confess that in the excitement of the anarchists I had forgotten
+it, but now I recalled that for several days I had been reading
+little paragraphs about robberies on the big estates on the Long
+Island shore of the Sound. One of the local correspondents had
+called the robber a "phantom bandit," but I had thought it nothing
+more than an attempt to make good copy out of a rather ordinary
+occurrence.
+
+"Well," he hurried on, "that's the reason why I have been 'taken
+up by society,' as you so elegantly phrase it. From the secret
+hiding-places of the boudoirs and safes of fashionable women at
+Bluffwood, thousands of dollars' worth of jewels and other
+trinkets have mysteriously vanished. Of course you'll come along.
+Why, it will be just the story to tone up that alleged page of
+society news you hand out in the Sunday Star. There--we're quits
+now. Seriously, though, Walter, it really seems to be a very
+baffling case, or rather series of cases. The whole colony out
+there is terrorized. They don't know who the robber is, or how he
+operates, or who will be the next victim, but his skill and
+success seem almost uncanny. Mr. Verplanck has put one of his cars
+at my disposal and I'm up here at the laboratory gathering some
+apparatus that may be useful. I'll pick you up anywhere between
+this and the Bridge--how about Columbus Circle in half an hour?"
+
+"Good," I agreed, deciding quickly from his tone and manner of
+assurance that it would be a case I could not afford to miss.
+
+The Stuyvesant Verplancks, I knew, were among the leaders of the
+rather recherche society at Bluffwood, and the pace at which
+Bluffwood moved and had its being was such as to guarantee a good
+story in one way or another.
+
+"Why," remarked Kennedy, as we sped out over the picturesque roads
+of the north shore of Long Island, "this fellow, or fellows, seems
+to have taken the measure of all the wealthy members of the
+exclusive organizations out there--the Westport Yacht Club, the
+Bluffwood Country Club, the North Shore Hunt, and all of them.
+It's a positive scandal, the ease with which he seems to come and
+go without detection, striking now here, now there, often at
+places that it seems physically impossible to get at, and yet
+always with the same diabolical skill and success. One night he
+will take some baubles worth thousands, the next pass them by for
+something apparently of no value at all, a piece of bric-a-brac, a
+bundle of letters, anything."
+
+"Seems purposeless, insane, doesn't it?" I put in.
+
+"Not when he always takes something--often more valuable than
+money," returned Craig.
+
+He leaned back in the car and surveyed the glimpses of bay and
+countryside as we were whisked by the breaks in the trees.
+
+"Walter," he remarked meditatively, "have you ever considered the
+possibilities of blackmail if the right sort of evidence were
+obtained under this new 'white-slavery act'? Scandals that some of
+the fast set may be inclined to wink at, that at worst used to end
+in Reno, become felonies with federal prison sentences looming up
+in the background. Think it over."
+
+Stuyvesant Verplanck had telephoned rather hurriedly to Craig
+earlier in the day, retaining his services, but telling only in
+the briefest way of the extent of the depredations, and hinting
+that more than jewelry might be at stake.
+
+It was a pleasant ride, but we finished it in silence. Verplanck
+was, as I recalled, a large masterful man, one of those who
+demanded and liked large things--such as the estate of several
+hundred acres which we at last entered.
+
+It was on a neck of land with the restless waters of the Sound on
+one side and the calmer waters of the bay on the other. Westport
+Bay lay in a beautifully wooded, hilly country, and the house
+itself was on an elevation, with a huge sweep of terraced lawn
+before it down to the water's edge. All around, for miles, were
+other large estates, a veritable colony of wealth.
+
+As we pulled up under the broad stone porte-cochere, Verplanck,
+who had been expecting us, led the way into his library, a great
+room, literally crowded with curios and objects of art which he
+had collected on his travels. It was a superb mental workshop,
+overlooking the bay, with a stretch of several miles of sheltered
+water.
+
+"You will recall," began Verplanck, wasting no time over
+preliminaries, but plunging directly into the subject, "that the
+prominent robberies of late have been at seacoast resorts,
+especially on the shores of Long Island Sound, within, say, a
+hundred miles of New York. There has been a great deal of talk
+about dark and muffled automobiles that have conveyed mysterious
+parties swiftly and silently across country.
+
+"My theory," he went on self-assertively, "is that the attack has
+been made always along water routes. Under shadow of darkness, it
+is easy to slip into one of the sheltered coves or miniature
+fiords with which the north coast of the Island abounds, land a
+cut-throat crew primed with exact information of the treasure on
+some of these estates. Once the booty is secured, the criminal
+could put out again into the Sound without leaving a clue."
+
+He seemed to be considering his theory. "Perhaps the robberies
+last summer at Narragansett, Newport, and a dozen other New
+England places were perpetrated by the same cracksman. I believe,"
+he concluded, lowering his voice, "that there plies to-day on the
+wide waters of the Sound a slim, swift motor boat which wears the
+air of a pleasure craft, yet is as black a pirate as ever flew the
+Jolly Roger. She may at this moment be anchored off some exclusive
+yacht club, flying the respectable burgee of the club--who knows?"
+
+He paused as if his deductions settled the case so far. He would
+have resumed in the same vein, if the door had not opened. A lady
+in a cobwebby gown entered the room. She was of middle age, but
+had retained her youth with a skill that her sisters of less
+leisure always envy. Evidently she had not expected to find
+anyone, yet nothing seemed to disconcert her.
+
+"Mrs. Verplanck," her husband introduced, "Professor Kennedy and
+his associate, Mr. Jameson--those detectives we have heard about.
+We were discussing the robberies."
+
+"Oh, yes," she said, smiling, "my husband has been thinking of
+forming himself into a vigilance committee. The local authorities
+are all at sea."
+
+I thought there was a trace of something veiled in the remark and
+fancied, not only then but later, that there was an air of
+constraint between the couple.
+
+"You have not been robbed yourself?" queried Craig tentatively.
+
+"Indeed we have," exclaimed Verplanck quickly. "The other night I
+was awakened by the noise of some one down here in this very
+library. I fired a shot, wild, and shouted, but before I could get
+down here the intruder had fled through a window, and half rolling
+down the terraces. Mrs. Verplanck was awakened by the rumpus and
+both of us heard a peculiar whirring noise."
+
+"Like an automobile muffled down," she put in.
+
+"No," he asserted vigorously, "more like a powerful motor boat,
+one with the exhaust under water."
+
+"Well," she shrugged, "at any rate, we saw no one."
+
+"Did the intruder get anything?"
+
+"That's the lucky part. He had just opened this safe apparently
+and begun to ransack it. This is my private safe. Mrs. Verplanck
+has another built into her own room upstairs where she keeps her
+jewels."
+
+"It is not a very modern safe, is it?" ventured Kennedy. "The
+fellow ripped off the outer casing with what they call a 'can-
+opener.'"
+
+"No. I keep it against fire rather than burglars. But he
+overlooked a box of valuable heirlooms, some silver with the
+Verplanck arms. I think I must have scared him off just in time.
+He seized a package in the safe, but it was only some business
+correspondence. I don't relish having lost it, particularly. It
+related to a gentlemen's agreement a number of us had in the
+recent cotton corner. I suppose the Government would like to have
+it. But--here's the point. If it is so easy to get in and get
+away, no one in Bluffwood is safe."
+
+"Why, he robbed the Montgomery Carter place the other night,"
+remarked Mrs. Verplanck, "and almost got a lot of old Mrs.
+Carter's jewels as well as stuff belonging to her son, Montgomery,
+Junior. That was the first robbery. Mr. Carter, that is Junior--
+Monty, everyone calls him--and his chauffeur almost captured the
+fellow, but he managed to escape in the woods."
+
+"In the woods?" repeated Craig.
+
+Mrs. Verplanck nodded. "But they saved the loot he was about to
+take."
+
+"Oh, no one is safe any more," reiterated Verplanck. "Carter seems
+to be the only one who has had a real chance at him, and he was
+able to get away neatly."
+
+"But he's not the only one who got off without a loss," she put in
+significantly. "The last visit--" Then she paused.
+
+"Where was the last attempt?" asked Kennedy.
+
+"At the house of Mrs. Hollingsworth--around the point on this side
+of the bay. You can't see it from here."
+
+"I'd like to go there," remarked Kennedy.
+
+"Very well. Car or boat?"
+
+"Boat, I think."
+
+"Suppose we go in my little runabout, the Streamline II? She's as
+fast as any ordinary automobile."
+
+"Very good. Then we can get an idea of the harbor."
+
+"I'll telephone first that we are coming," said Verplanck.
+
+"I think I'll go, too," considered Mrs. Verplanck, ringing for a
+heavy wrap.
+
+"Just as you please," said Verplanck.
+
+The Streamline was a three-stepped boat which. Verplanck had built
+for racing, a beautiful craft, managed much like a racing
+automobile. As she started from the dock, the purring drone of her
+eight cylinders sent her feathering over the waves like a skipping
+stone. She sank back into the water, her bow leaping upward, a
+cloud of spray in her wake, like a waterspout.
+
+Mrs. Hollingsworth was a wealthy divorcee, living rather quietly
+with her two children, of whom the courts had awarded her the
+care. She was a striking woman, one of those for whom the new
+styles of dress seem especially to have been designed. I gathered,
+however, that she was not on very good terms with the little
+Westport clique in which the Verplancks moved, or at least not
+with Mrs. Verplanck. The two women seemed to regard each other
+rather coldly, I thought, although Mr. Verplanck, man-like, seemed
+to scorn any distinctions and was more than cordial. I wondered
+why Mrs. Verplanck had come.
+
+The Hollingsworth house was a beautiful little place down the bay
+from the Yacht Club, but not as far as Verplanck's, or the Carter
+estate, which was opposite.
+
+"Yes," replied Mrs. Hollingsworth when the reason for our visit
+had been explained, "the attempt was a failure. I happened to be
+awake, rather late, or perhaps you would call it early. I thought
+I heard a noise as if some one was trying to break into the
+drawing-room through the window. I switched on all the lights. I
+have them arranged so for just that purpose of scaring off
+intruders. Then, as I looked out of my window on the second floor,
+I fancied I could see a dark figure slink into the shadow of the
+shrubbery at the side of the house. Then there was a whirr. It
+might have been an automobile, although it sounded differently
+from that--more like a motor boat. At any rate, there was no trace
+of a car that we could discover in the morning. The road had been
+oiled, too, and a car would have left marks. And yet some one was
+here. There were marks on the drawing-room window just where I
+heard the sounds."
+
+Who could it be? I asked myself as we left. I knew that the great
+army of chauffeurs was infested with thieves, thugs and gunmen.
+Then, too, there were maids, always useful as scouts for these
+corsairs who prey on the rich. Yet so adroitly had everything been
+done in these cases that not a clue seemed to have been left
+behind by which to trace the thief.
+
+We returned to Verplanck's in the Streamline in record time,
+dined, and then found McNeill, a local detective, waiting to add
+his quota of information. McNeill was of the square-toed, double-
+chinned, bull-necked variety, just the man to take along if there
+was any fighting. He had, however, very little to add to the
+solution of the mystery, apparently believing in the chauffeur-
+and-maid theory.
+
+It was too late to do anything more that night, and we sat on the
+Verplanck porch, overlooking the beautiful harbor. It was a black,
+inky night, with no moon, one of those nights when the myriad
+lights on the boats were mere points in the darkness. As we looked
+out over the water, considering the case which as yet we had
+hardly started on, Kennedy seemed engrossed in the study in black.
+
+"I thought I saw a moving light for an instant across the bay,
+above the boats, and as though it were in the darkness of the
+hills on the other side. Is there a road over there, above the
+Carter house?" he asked suddenly.
+
+"There is a road part of the way on the crest of the hill,"
+replied Mrs. Verplanck. "You can see a car on it, now and then,
+through the trees, like a moving light."
+
+"Over there, I mean," reiterated Kennedy, indicating the light as
+it flashed now faintly, then disappeared, to reappear further
+along, like a gigantic firefly in the night.
+
+"N-no," said Verplanck. "I don't think the road runs down as far
+as that. It is further up the bay."
+
+"What is it then?" asked Kennedy, half to himself. "It seems to be
+traveling rapidly. Now it must be about opposite the Carter house.
+There--it has gone."
+
+We continued to watch for several minutes, but it did not
+reappear. Could it have been a light on the mast of a boat moving
+rapidly up the bay and perhaps nearer to us than we suspected?
+Nothing further happened, however, and we retired early, expecting
+to start with fresh minds on the case in the morning. Several
+watchmen whom Verplanck employed both on the shore and along the
+driveways were left guarding every possible entrance to the
+estate.
+
+Yet the next morning as we met in the cheery east breakfast room,
+Verplanck's gardener came in, hat in hand, with much suppressed
+excitement.
+
+In his hand he held an orange which he had found in the shrubbery
+underneath the windows of the house. In it was stuck a long nail
+and to the nail was fastened a tag.
+
+Kennedy read it quickly.
+
+"If this had been a bomb, you and your detectives would never have
+known what struck you.
+
+"AQUAERO."
+
+
+
+
+CHAPTER V
+
+THE ULTRA-VIOLET RAY
+
+
+"Good Gad, man!" exclaimed Verplanck, who had read it over Craig's
+shoulder. "What do you make of THAT?"
+
+Kennedy merely shook his head. Mrs. Verplanck was the calmest of
+all.
+
+"The light," I cried. "You remember the light? Could it have been
+a signal to some one on this side of the bay, a signal light in
+the woods?"
+
+"Possibly," commented Kennedy absently, adding, "Robbery with this
+fellow seems to be an art as carefully strategized as a promoter's
+plan or a merchant's trade campaign. I think I'll run over this
+morning and see if there is any trace of anything on the Carter
+estate."
+
+Just then the telephone rang insistently. It was McNeill, much
+excited, though he had not heard of the orange incident. Verplanck
+answered the call.
+
+"Have you heard the news?" asked McNeill. "They report this
+morning that that fellow must have turned up last night at Belle
+Aire."
+
+"Belle Aire? Why, man, that's fifty miles away and on the other
+side of the island. He was here last night," and Verplanck related
+briefly the find of the morning. "No boat could get around the
+island in that time and as for a car--those roads are almost
+impossible at night."
+
+"Can't help it," returned McNeill doggedly. "The Halstead estate
+out at Belle Aire was robbed last night. It's spooky all right."
+
+"Tell McNeill I want to see him--will meet him in the village
+directly," cut in Craig before Verplanck had finished.
+
+We bolted a hasty breakfast and in one of Verplanck's cars hurried
+to meet McNeill.
+
+"What do you intend doing?" he asked helplessly, as Kennedy
+finished his recital of the queer doings of the night before.
+
+"I'm going out now to look around the Carter place. Can you come
+along?"
+
+"Surely," agreed McNeill, climbing into the car. "You know him?"
+
+"No."
+
+"Then I'll introduce you. Queer chap, Carter. He's a lawyer,
+although I don't think he has much practice, except managing his
+mother's estate."
+
+McNeill settled back in the luxurious car with an exclamation of
+satisfaction.
+
+"What do you think of Verplanck?" he asked.
+
+"He seems to me to be a very public-spirited man," answered
+Kennedy discreetly.
+
+That, however, was not what McNeill meant and he ignored it. And
+so for the next ten minutes we were entertained with a little
+retail scandal of Westport and Bluffwood, including a tale that
+seemed to have gained currency that Verplanck and Mrs.
+Hollingsworth were too friendly to please Mrs. Verplanck. I set
+the whole thing down to the hostility and jealousy of the towns
+people who misinterpret everything possible in the smart set,
+although I could not help recalling how quickly she had spoken
+when we had visited the Hollingsworth house in the Streamline the
+day before.
+
+Montgomery Carter happened to be at home and, at least openly,
+interposed no objection to our going about the grounds.
+
+"You see," explained Kennedy, watching the effect of his words as
+if to note whether Carter himself had noticed anything unusual the
+night before, "we saw a light moving over here last night. To tell
+the truth, I half expected you would have a story to add to ours,
+of a second visit."
+
+Carter smiled. "No objection at all. I'm simply nonplussed at the
+nerve of this fellow, coming back again. I guess you've heard what
+a narrow squeak he had with me. You're welcome to go anywhere,
+just so long as you don't disturb my study down there in the
+boathouse. I use that because it overlooks the bay--just the place
+to study over knotty legal problems."
+
+Back of, or in front of the Carter house, according as you fancied
+it faced the bay or not, was the boathouse, built by Carter's
+father, who had been a great yachtsman in his day and commodore of
+the club. His son had not gone in much for water sports and had
+converted the corner underneath a sort of observation tower into a
+sort of country law office.
+
+"There has always seemed to me to be something strange about that
+boathouse since the old man died," remarked McNeill in a half
+whisper as we left Carter. "He always keeps it locked and never
+lets anyone go in there, although they say he has it fitted
+beautifully with hundreds of volumes of law books, too."
+
+Kennedy had been climbing the hill back of the house and now
+paused to look about. Below was the Carter garage.
+
+"By the way," exclaimed McNeill, as if he had at last hit on a
+great discovery, "Carter has a new chauffeur, a fellow named
+Wickham. I just saw him driving down to the village. He's a chap
+that it might pay us to watch--a newcomer, smart as a steel trap,
+they say, but not much of a talker." "Suppose you take that job--
+watch him," encouraged Kennedy. "We can't know too much about
+strangers here, McNeill."
+
+"That's right," agreed the detective. "I'll follow him back to the
+village and get a line on him."
+
+"Don't be easily discouraged," added Kennedy, as McNeill started
+down the hill to the garage. "If he is a fox he'll try to throw
+you off the trail. Hang on."
+
+"What was that for?" I asked as the detective disappeared. "Did
+you want to get rid of him?"
+
+"Partly," replied Craig, descending slowly, after a long survey of
+the surrounding country.
+
+We had reached the garage, deserted now except for our own car.
+
+"I'd like to investigate that tower," remarked Kennedy with a keen
+look at me, "if it could be done without seeming to violate Mr.
+Carter's hospitality."
+
+"Well," I observed, my eye catching a ladder beside the garage,
+"there's a ladder. We can do no more than try."
+
+He walked over to the automobile, took a little package out,
+slipped it into his pocket, and a few minutes later we had set the
+ladder up against the side of the boathouse farthest away from the
+house. It was the work of only a moment for Kennedy to scale it
+and prowl across the roof to the tower, while I stood guard at the
+foot.
+
+"No one has been up there recently," he panted breathlessly as he
+rejoined me. "There isn't a sign."
+
+We took the ladder quietly back to the garage, then Kennedy led
+the way down the shore to a sort of little summerhouse cut off
+from the boathouse and garage by the trees, though over the top of
+a hedge one could still see the boathouse tower.
+
+We sat down, and Craig filled his lungs with the good salt air,
+sweeping his eye about the blue and green panorama as though this
+were a holiday and not a mystery case.
+
+"Walter," he said at length, "I wish you'd take the car and go
+around to Verplanck's. I don't think you can see the tower through
+the trees, but I should like to be sure."
+
+I found that it could not be seen, though I tried all over the
+place and got myself disliked by the gardener and suspected by a
+watchman with a dog.
+
+It could not have been from the tower of the boathouse that we had
+seen the light, and I hurried back to Craig to tell him so. But
+when I returned, I found that he was impatiently pacing the little
+rustic summerhouse, no longer interested in what he had sent me to
+find out.
+
+"What has happened?" I asked eagerly.
+
+"Just come out here and I'll show you something," he replied,
+leaving the summerhouse and approaching the boathouse from the
+other side of the hedge, on the beach, so that the house itself
+cut us off from observation from Carter's.
+
+"I fixed a lens on the top of that tower when I was up there," he
+explained, pointing up at it. "It must be about fifty feet high.
+From there, you see, it throws a reflection down to this mirror. I
+did it because through a skylight in the tower I could read
+whatever was written by anyone sitting at Carter's desk in the
+corner under it."
+
+"Read?" I repeated, mystified.
+
+"Yes, by invisible light," he continued. "This invisible light
+business, you know, is pretty well understood by this time. I was
+only repeating what was suggested once by Professor Wood of Johns
+Hopkins. Practically all sources of light, you understand, give
+out more or less ultraviolet light, which plays no part in vision
+whatever. The human eye is sensitive to but few of the light rays
+that reach it, and if our eyes were constituted just the least bit
+differently we should have an entirely different set of images.
+
+"But by the use of various devices we can, as it were, translate
+these ultraviolet rays into terms of what the human eye can see.
+In order to do it, all the visible light rays which show us the
+thing as we see it--the tree green, the sky blue--must be cut off.
+So in taking an ultraviolet photograph a screen must be used which
+will be opaque to these visible rays and yet will let the
+ultraviolet rays through to form the image. That gave Professor
+Wood a lot of trouble. Glass won't do, for glass cuts off the
+ultraviolet rays entirely. Quartz is a very good medium, but it
+does not cut off all the visible light. In fact there is only one
+thing that will do the work, and that is metallic silver."
+
+I could not fathom what he was driving at, but the fascination of
+Kennedy himself was quite sufficient.
+
+"Silver," he went on, "is all right if the objects can be
+illuminated by an electric spark or some other source rich in the
+rays. But it isn't entirely satisfactory when sunlight is
+concerned, for various reasons that I need not bore you with.
+Professor Wood has worked out a process of depositing nickel on
+glass. That's it up there," he concluded, wheeling a lower
+reflector about until it caught the image of the afternoon sun
+thrown from the lens on the top of the tower.
+
+"You see," he resumed, "that upper lens is concave so that it
+enlarges tremendously. I can do some wonderful tricks with that."
+
+I had been lighting a cigarette and held a box of safety wind
+matches in my hand.
+
+"Give me that matchbox," he asked.
+
+He placed it at the foot of the tower. Then he went off, I should
+say, without exaggeration, a hundred feet.
+
+The lettering on the matchbox could be seen in the silvered
+mirror, enlarged to such a point that the letters were plainly
+visible!
+
+"Think of the possibilities in that," he added excitedly. "I saw
+them at once. You can read what some one is writing at a desk a
+hundred, perhaps two hundred feet away."
+
+"Yes," I cried, more interested in the practical aspects of it
+than in the mechanics and optics. "What have you found?"
+
+"Some one came into the boathouse while you were away," he said.
+"He had a note. It read, 'Those new detectives are watching
+everything. We must have the evidence. You must get those letters
+to-night, without fail.'"
+
+"Letters--evidence," I repeated. "Who wrote it? Who received it?"
+
+"I couldn't see over the hedge who had entered the boathouse, and
+by the time I got around here he was gone."
+
+"Was it Wickham--or intended for Wickham?" I asked.
+
+Kennedy shrugged his shoulders.
+
+"We'll gain nothing by staying here," he said. "There is just one
+possibility in the case, and I can guard against that only by
+returning to Verplanck's and getting some of that stuff I brought
+up here with me. Let us go."
+
+Late in the afternoon though it was, after our return, Kennedy
+insisted on hurrying from Verplanck's to the Yacht Club up the
+bay. It was a large building, extending out into the water on made
+land, from which ran a long, substantial dock. He had stopped long
+enough only to ask Verplanck to lend him the services of his best
+mechanician, a Frenchman named Armand.
+
+On the end of the yacht club dock Kennedy and Armand set up a
+large affair which looked like a mortar. I watched curiously,
+dividing my attention between them and the splendid view of the
+harbor which the end of the dock commanded on all sides.
+
+"What is this?" I asked finally. "Fireworks?"
+
+"A rocket mortar of light weight," explained Kennedy, then dropped
+into French as he explained to Armand the manipulation of the
+thing.
+
+There was a searchlight near by on the dock.
+
+"You can use that?" queried Kennedy.
+
+"Oh, yes. Mr. Verplanck, he is vice-commodore of the club. Oh,
+yes, I can use that. Why, Monsieur?"
+
+Kennedy had uncovered a round brass case. It did not seem to
+amount to much, as compared to some of the complicated apparatus
+he had used. In it was a four-sided prism of glass--I should have
+said, cut off the corner of a huge glass cube.
+
+He handed it to us.
+
+"Look in it," he said.
+
+It certainly was about the most curious piece of crystal gazing I
+had ever done. Turn the thing any way I pleased and I could see my
+face in it, just as in an ordinary mirror.
+
+"What do you call it?" Armand asked, much interested.
+
+"A triple mirror," replied Kennedy, and again, half in English and
+half in French, neither of which I could follow, he explained the
+use of the mirror to the mechanician.
+
+We were returning up the dock, leaving Armand with instructions to
+be at the club at dusk, when we met McNeill, tired and disgusted.
+
+"What luck?" asked Kennedy.
+
+"Nothing," he returned. "I had a 'short' shadow and a 'long'
+shadow at Wickham's heels all day. You know what I mean. Instead
+of one man, two--the second sleuthing in the other's tracks. If he
+escaped Number One, Number Two would take it up, and I was ready
+to move up into Number Two's place. They kept him in sight about
+all the time. Not a fact. But then, of course, we don't know what
+he was doing before we took up tailing him. Say," he added, "I
+have just got word from an agency with which I correspond in New
+York that it is reported that a yeggman named 'Australia Mac,' a
+very daring and clever chap, has been attempting to dispose of
+some of the goods which we know have been stolen through one of
+the worst 'fences' in New York."
+
+"Is that all?" asked Craig, with the mention of Australia Mac
+showing the first real interest yet in anything that McNeill had
+done since we met him the night before.
+
+"All so far. I wired for more details immediately."
+
+"Do you know anything about this Australia Mac?"
+
+"Not much. No one does. He's a new man, it seems, to the police
+here."
+
+"Be here at eight o'clock, McNeill," said Craig, as we left the
+club for Verplanck's. "If you can find out more about this
+yeggman, so much the better."
+
+"Have you made any progress?" asked Verplanck as we entered the
+estate a few minutes later.
+
+"Yes," returned Craig, telling only enough to whet his interest.
+"There's a clue, as I half expected, from New York, too. But we
+are so far away that we'll have to stick to my original plan. You
+can trust Armand?"
+
+"Absolutely."
+
+"Then we shall transfer our activity to the Yacht Club to-night,"
+was all that Kennedy vouchsafed.
+
+
+
+
+CHAPTER VI
+
+THE TRIPLE MIRROR
+
+
+It was the regular Saturday night dance at the club, a brilliant
+spectacle, faces that radiated pleasure, gowns that for startling
+combinations of color would have shamed a Futurist, music that set
+the feet tapping irresistibly--a scene which I shall pass over
+because it really has no part in the story.
+
+The fascination of the ballroom was utterly lost on Craig. "Think
+of all the houses only half guarded about here to-night," he
+mused, as we joined Armand and McNeill on the end of the dock. I
+could not help noting that that was the only idea which the gay,
+variegated, sparkling tango throng conveyed to him.
+
+In front of the club was strung out a long line of cars, and at
+the dock several speed boats of national and international
+reputation, among them the famous Streamline II, at our instant
+beck and call. In it Craig had already placed some rather bulky
+pieces of apparatus, as well as a brass case containing a second
+triple mirror like that which he had left with Armand.
+
+With McNeill, I walked back along the pier, leaving Kennedy with
+Armand, until we came to the wide porch, where we joined the
+wallflowers and the rocking-chair fleet. Mrs. Verplanck, I
+observed, was a beautiful dancer. I picked her out in the throng
+immediately, dancing with Carter.
+
+McNeill tugged at my sleeve. Without a word I saw what he meant me
+to see. Verplanck and Mrs. Hollingsworth were dancing together.
+Just then, across the porch I caught sight of Kennedy at one of
+the wide windows. He was trying to attract Verplanck's attention,
+and as he did so I worked my way through the throng of chatting
+couples leaving the floor until I reached him. Verplanck,
+oblivious, finished the dance; then, seeming to recollect that he
+had something to attend to, caught sight of us, and ran off during
+the intermission from the gay crowd to which he resigned Mrs.
+Hollingsworth.
+
+"What is it?" he asked.
+
+"There's that light down the bay," whispered Kennedy.
+
+Instantly Verplanck forgot about the dance.
+
+"Where?" he asked.
+
+"In the same place."
+
+I had not noticed, but Mrs. Verplanck, woman-like, had been able
+to watch several things at once. She had seen us and had joined
+us.
+
+"Would you like to run down there in the Streamline?" he asked.
+"It will only take a few minutes."
+
+"Very much."
+
+"What is it--that light again?" she asked, as she joined us in
+walking down the dock.
+
+"Yes," answered her husband, pausing to look for a moment at the
+stuff Kennedy had left with Armand. Mrs. Verplanck leaned over the
+Streamline, turned as she saw me, and said: "I wish I could go
+with you. But evening dress is not the thing for a shivery night
+in a speed boat. I think I know as much about it as Mr. Verplanck.
+Are you going to leave Armand?"
+
+"Yes," replied Kennedy, taking his place beside Verplanck, who was
+seated at the steering wheel. "Walter and McNeill, if you two will
+sit back there, we're ready. All right."
+
+Armand had cast us off and Mrs. Verplanck waved from the end of
+the float as the Streamline quickly shot out into the night, a
+buzzing, throbbing shape of mahogany and brass, with her exhausts
+sticking out like funnels and booming like a pipe organ. It took
+her only seconds to eat into the miles.
+
+"A little more to port," said Kennedy, as Verplanck swung her
+around.
+
+Just then the steady droning of the engine seemed a bit less
+rhythmical. Verplanck throttled her down, but it had no effect. He
+shut her off. Something was wrong. As he crawled out into the
+space forward of us where the engine was, it seemed as if the
+Streamline had broken down suddenly and completely.
+
+Here we were floundering around in the middle of the bay.
+
+"Chuck-chuck-chuck," came in quick staccato out of the night. It
+was Montgomery Carter, alone, on his way across the bay from the
+club, in his own boat.
+
+"Hello--Carter," called Verplanck.
+
+"Hello, Verplanck. What's the matter?"
+
+"Don't know. Engine trouble of some kind. Can you give us a line?"
+
+"I've got to go down to the house," he said, ranging up near us.
+"Then I can take you back. Perhaps I'd better get you out of the
+way of any other boats first. You don't mind going over and then
+back?"
+
+Verplanck looked at Craig. "On the contrary," muttered Craig, as
+he made fast the welcome line.
+
+The Carter dock was some three miles from the club on the other
+side of the bay. As we came up to it, Carter shut off his engine,
+bent over it a moment, made fast, and left us with a hurried,
+"Wait here."
+
+Suddenly, overhead, we heard a peculiar whirring noise that seemed
+to vibrate through the air. Something huge, black, monster-like,
+slid down a board runway into the water, traveled a few feet, in
+white suds and spray, rose in the darkness--and was gone!
+
+As the thing disappeared, I thought I could hear a mocking laugh
+flung back at us.
+
+"What is it?" I asked, straining my eyes at what had seemed for an
+instant like a great flying fish with finny tail and huge fins at
+the sides and above.
+
+"'Aquaero,'" quoted Kennedy quickly. "Don't you understand--a
+hydroaeroplane--a flying boat. There are hundreds of privately
+owned flying boats now wherever there is navigable water. That was
+the secret of Carter's boathouse, of the light we saw in the air."
+
+"But this Aquaero--who is he?" persisted McNeill. "Carter--
+Wickham--Australia Mac?"
+
+We looked at each other blankly. No one said a word. We were
+captured, just as effectively as if we were ironed in a dungeon.
+There were the black water, the distant lights, which at any other
+time I should have said would have been beautiful.
+
+Kennedy had sprung into Carter's boat.
+
+"The deuce," he exclaimed. "He's put her out of business."
+
+Verplanck, chagrined, had been going over his own engine
+feverishly. "Do you see that?" he asked suddenly, holding up in
+the light of a lantern a little nut which he had picked out of the
+complicated machinery. "It never belonged to this engine. Some one
+placed it there, knowing it would work its way into a vital part
+with the vibration."
+
+Who was the person, the only one who could have done it? The
+answer was on my lips, but I repressed it. Mrs. Verplanck herself
+had been bending over the engine when last I saw her. All at once
+it flashed over me that she knew more about the phantom bandit
+than she had admitted. Yet what possible object could she have had
+in putting the Streamline out of commission?
+
+My mind was working rapidly, piecing together the fragmentary
+facts. The remark of Kennedy, long before, instantly assumed new
+significance. What were the possibilities of blackmail in the
+right sort of evidence? The yeggman had been after what was more
+valuable than jewels--letters! Whose? Suddenly I saw the
+situation. Carter had not been robbed at all. He was in league
+with the robber. That much was a blind to divert suspicion. He was
+a lawyer--some one's lawyer. I recalled the message about letters
+and evidence, and as I did so there came to mind a picture of
+Carter and the woman he had been dancing with. In return for his
+inside information about the jewels of the wealthy homes of
+Bluffwood, the yeggman was to get something of interest and
+importance to his client.
+
+The situation called for instant action. Yet what could we do,
+marooned on the other side of the bay?
+
+From the Club dock a long finger of light swept out into the
+night, plainly enough near the dock, but diffused and disclosing
+nothing in the distance. Armand had trained it down the bay in the
+direction we had taken, but by the time the beam reached us it was
+so weak that it was lost.
+
+Craig had leaped up on the Carter dock and was capping and
+uncapping with the brass cover the package which contained the
+triple mirror.
+
+Still in the distance I could see the wide path of light, aimed
+toward us, but of no avail.
+
+"What are you doing?" I asked.
+
+"Using the triple mirror to signal to Armand. It is something
+better than wireless. Wireless requires heavy and complicated
+apparatus. This is portable, heatless, almost weightless, a source
+of light depending for its power on another source of light at a
+great distance."
+
+I wondered how Armand could ever detect its feeble ray.
+
+"Even in the case of a rolling ship," Kennedy continued,
+alternately covering and uncovering the mirror, "the beam of light
+which this mirror reflects always goes back, unerring, to its
+source. It would do so from an aeroplane, so high in the air that
+it could not be located. The returning beam is invisible to anyone
+not immediately in the path of the ray, and the ray always goes to
+the observer. It is simply a matter of pure mathematics
+practically applied. The angle of incidence equals the angle of
+reflection. There is not a variation of a foot in two miles."
+
+"What message are you sending him?" asked Verplanck.
+
+"To tell Mrs. Hollingsworth to hurry home immediately," Kennedy
+replied, still flashing the letters according to his code.
+
+"Mrs. Hollingsworth?" repeated Verplanck, looking up.
+
+"Yes. This hydroaeroplane yeggman is after something besides
+jewels to-night. Were those letters that were stolen from you the
+only ones you had in the safe?"
+
+Verplanck looked up quickly. "Yes, yes. Of course."
+
+"You had none from a woman--"
+
+"No," he almost shouted. Of a sudden it seemed to dawn on him what
+Kennedy was driving at--the robbery of his own house with no loss
+except of a packet of letters on business, followed by the attempt
+on Mrs. Hollingsworth. "Do you think I'd keep dynamite, even in
+the safe?"
+
+To hide his confusion he had turned and was bending again over the
+engine.
+
+"How is it?" asked Kennedy, his signaling over.
+
+"Able to run on four cylinders and one propeller," replied
+Verplanck.
+
+"Then let's try her. Watch the engine. I'll take the wheel."
+
+Limping along, the engine skipping and missing, the once peerless
+Streamline started back across the bay. Instead of heading toward
+the club, Kennedy pointed her bow somewhere between that and
+Verplanck's.
+
+"I wish Armand would get busy," he remarked, after glancing now
+and then in the direction of the club. "What can be the matter?"
+
+"What do you mean?" I asked.
+
+There came the boom as if of a gun far away in the direction in
+which he was looking, then another.
+
+"Oh, there it is. Good fellow. I suppose he had to deliver my
+message to Mrs. Hollingsworth himself first."
+
+From every quarter showed huge balls of fire, rising from the sea,
+as it were, with a brilliantly luminous flame.
+
+"What is it?" I asked, somewhat startled.
+
+"A German invention for use at night against torpedo and aeroplane
+attacks. From that mortar Armand has shot half a dozen bombs of
+phosphide of calcium which are hurled far into the darkness. They
+are so constructed that they float after a short plunge and are
+ignited on contact by the action of the salt water itself."
+
+It was a beautiful pyrotechnic display, lighting up the shore and
+hills of the bay as if by an unearthly flare.
+
+"There's that thing now!" exclaimed Kennedy.
+
+In the glow we could see a peculiar, birdlike figure flying
+through the air over toward the Hollingsworth house. It was the
+hydroaeroplane.
+
+Out from the little stretch of lawn under the accentuated shadow
+of the trees, she streaked into the air, swaying from side to side
+as the pilot operated the stabilizers on the ends of the planes to
+counteract the puffs of wind off the land.
+
+How could she ever be stopped?
+
+The Streamline, halting and limping, though she was, had almost
+crossed the bay before the light bombs had been fired by Armand.
+Every moment brought the flying boat nearer.
+
+She swerved. Evidently the pilot had seen us at last and realized
+who we were. I was so engrossed watching the thing that I had not
+noticed that Kennedy had given the wheel to Verplanck and was
+standing in the bow, endeavoring to sight what looked like a huge
+gun.
+
+In rapid succession half a dozen shots rang out. I fancied I could
+almost hear the ripping and tearing of the tough rubber-coated
+silken wings of the hydroaeroplane as the wind widened the
+perforation the gun had made.
+
+She had not been flying high, but now she swooped down almost like
+a gull, seeking to rest on the water. We were headed toward her
+now, and as the flying boat sank I saw one of the passengers rise
+in his seat, swing his arm, and far out something splashed in the
+bay.
+
+On the water, with wings helpless, the flying boat was no match
+for the Streamline now. She struck at an acute angle, rebounded in
+the air for a moment, and with a hiss skittered along over the
+waves, planing with the help of her exhaust under the step of the
+boat.
+
+There she was, a hull, narrow, scow-bowed, like a hydroplane, with
+a long pointed stern and a cockpit for two men, near the bow.
+There were two wide, winglike planes, on a light latticework of
+wood covered with silk, trussed and wired like a kite frame, the
+upper plane about five feet above the lower, which was level with
+the boat deck. We could see the eight-cylindered engine which
+drove a two-bladed wooden propeller, and over the stern were the
+air rudder and the horizontal planes. There she was, the hobbled
+steed now of the phantom bandit who had accomplished the seemingly
+impossible.
+
+In spite of everything, however, the flying boat reached the shore
+a trifle ahead of us. As she did so both figures in her jumped,
+and one disappeared quickly up the bank, leaving the other alone.
+
+"Verplanck, McNeill--get him," cried Kennedy, as our own boat
+grated on the beach. "Come, Walter, we'll take the other one."
+
+The man had seen that there was no safety in flight. Down the
+shore he stood, without a hat, his hair blown pompadour by the
+wind.
+
+As we approached Carter turned superciliously, unbuttoning his
+bulky khaki life preserver jacket.
+
+"Well?" he asked coolly.
+
+Not for a moment did Kennedy allow the assumed coolness to take
+him back, knowing that Carter's delay did not cover the retreat of
+the other man.
+
+"So," Craig exclaimed, "you are the--the air pirate?"
+
+Carter disdained to reply.
+
+"It was you who suggested the millionaire households, full of
+jewels, silver and gold, only half guarded; you, who knew the
+habits of the people; you, who traded that information in return
+for another piece of thievery by your partner, Australia Mac--
+Wickham he called himself here in Bluffwood. It was you---"
+
+A car drove up hastily, and I noted that we were still on the
+Hollingsworth estate. Mrs. Hollingsworth had seen us and had
+driven over toward us.
+
+"Montgomery!" she cried, startled.
+
+"Yes," said Kennedy quickly, "air pirate and lawyer for Mrs.
+Verplanck in the suit which she contemplated bringing--"
+
+Mrs. Hollingsworth grew pale under the ghastly, flickering light
+from the bay.
+
+"Oh!" she cried, realizing at what Kennedy hinted, "the letters!"
+
+"At the bottom of the harbor, now," said Kennedy. "Mr. Verplanck
+tells me he has destroyed his. The past is blotted out as far as
+that is concerned. The future is--for you three to determine. For
+the present I've caught a yeggman and a blackmailer."
+
+
+
+
+CHAPTER VII
+
+THE WIRELESS WIRETAPPERS
+
+
+Kennedy did not wait at Bluffwood longer than was necessary. It
+was easy enough now to silence Montgomery Carter, and the
+reconciliation of the Verplancks was assured. In the Star I made
+the case appear at the time to involve merely the capture of
+Australia Mac.
+
+When I dropped into the office the next day as usual, I found that
+I had another assignment that would take me out on Long Island.
+The story looked promising and I was rather pleased to get it.
+
+"Bound for Seaville, I'll wager," sounded a familiar voice in my
+ear, as I hurried up to the train entrance at the Long Island
+corner of the Pennsylvania Station.
+
+I turned quickly, to find Kennedy just behind me, breathless and
+perspiring.
+
+"Er--yes," I stammered in surprise at seeing him so unexpectedly,
+"but where did you come from? How did you know?"
+
+"Let me introduce Mr. Jack Waldon," he went on, as we edged our
+way toward the gate, "the brother of Mrs. Tracy Edwards, who
+disappeared so strangely from the houseboat Lucie last night at
+Seaville. That is the case you're going to write up, isn't it?"
+
+It was then for the first time that I noticed the excited young
+man beside Kennedy was really his companion.
+
+I shook hands with Waldon, who gave me a grip that was both a
+greeting and an added impulse in our general direction through the
+wicket.
+
+"Might have known the Star would assign you to this Edwards case,"
+panted Kennedy, mopping his forehead, for the heat in the terminal
+was oppressive and the crowd, though not large, was closely
+packed. "Mr. Jameson is my right-hand man," he explained to
+Waldon, taking us each by the arm and urging us forward. "Waldon
+was afraid we might miss the train or I should have tried to get
+you, Walter, at the office."
+
+It was all done so suddenly that they quite took away what
+remaining breath I had, as we settled ourselves to swelter in the
+smoker instead of in the concourse. I did not even protest at the
+matter-of-fact assurance with which Craig assumed that his
+deduction as to my destination was correct.
+
+Waldon, a handsome young fellow in a flannel suit and yachting cap
+somewhat the worse for his evidently perturbed state of mind,
+seemed to eye me for the moment doubtfully, in spite of Kennedy's
+cordial greeting.
+
+"I've had all the first editions of the evening papers," I hinted
+as we sped through the tunnel, "but the stories seemed to be quite
+the same--pretty meager in details."
+
+"Yes," returned Waldon with a glance at Kennedy, "I tried to keep
+as much out of the papers as I could just now for Lucie's sake."
+
+"You needn't fear Jameson," remarked Kennedy.
+
+He fumbled in his pocket, then paused a moment and shot a glance
+of inquiry at Waldon, who nodded a mute acquiescence to him.
+
+"There seem to have been a number of very peculiar disappearances
+lately," resumed Kennedy, "but this case of Mrs. Edwards is by far
+the most extraordinary. Of course the Star hasn't had that--yet,"
+he concluded, handing me a sheet of notepaper.
+
+"Mr. Waldon didn't give it out, hoping to avoid scandal."
+
+I took the paper and read eagerly, in a woman's hand:
+
+"MY DEAR MISS FOX: I have been down here at Seaville on our
+houseboat, the Lucie, for several days for a purpose which now is
+accomplished.
+
+"Already I had my suspicions of you, from a source which I need
+not name. Therefore, when the Kronprinz got into wireless
+communication with the station at Seaville I determined through
+our own wireless on the Lucie to overhear whether there would be
+any exchange of messages between my husband and yourself.
+
+"I was able to overhear the whole thing and I want you to know
+that your secret is no longer a secret from me, and that I have
+already told Mr. Edwards that I know it. You ruin his life by your
+intimacy which you seem to want to keep up, although you know you
+have no right to do it, but you shall not ruin mine.
+
+"I am thoroughly disillusioned now. I have not decided on what
+steps to take, but--"
+
+Only a casual glance was necessary to show me that the writing
+seemed to grow more and more weak as it progressed, and the note
+stopped abruptly, as if the writer had been suddenly interrupted
+or some new idea had occurred to her.
+
+Hastily I tried to figure it out. Lucie Waldon, as everybody knew,
+was a famous beauty, a marvel of charm and daintiness, slender,
+with big, soulful, wistful eyes. Her marriage to Tracy Edwards,
+the wealthy plunger and stockbroker, had been a great social event
+the year before, and it was reputed at the time that Edwards had
+showered her with jewels and dresses to the wonder and talk even
+of society.
+
+As for Valerie Fox, I knew she had won quick recognition and even
+fame as a dancer in New York during the previous winter, and I
+recalled reading three or four days before that she had just
+returned on the Kronprinz from a trip abroad.
+
+"I don't suppose you have had time to see Miss Fox," I remarked.
+"Where is she?"
+
+"At Beach Park now, I think," replied Waldon, "a resort a few
+miles nearer the city on the south shore, where there is a large
+colony of actors."
+
+I handed back the letter to Kennedy.
+
+"What do you make of it?" he asked, as he folded it up and put it
+back into his pocket.
+
+"I hardly know what to say," I replied. "Of course there have been
+rumors, I believe, that all was not exactly like a honeymoon still
+with the Tracy Edwardses."
+
+"Yes," returned Waldon slowly, "I know myself that there has been
+some trouble, but nothing definite until I found this letter last
+night in my sister's room. She never said anything about it either
+to mother or myself. They haven't been much together during the
+summer, and last night when she disappeared Tracy was in the city.
+But I hadn't thought much about it before, for, of course, you
+know he has large financial interests that make him keep in pretty
+close touch with New York and this summer hasn't been a
+particularly good one on the stock exchange."
+
+"And," I put in, "a plunger doesn't always make the best of
+husbands. Perhaps there is temperament to be reckoned with here."
+
+"There seem to be a good many things to be reckoned with," Craig
+considered. "For example, here's a houseboat, the Lucie, a
+palatial affair, cruising about aimlessly, with a beautiful woman
+on it. She gives a little party, in the absence of her husband, to
+her brother, his fiancee and her mother, who visit her from his
+yacht, the Nautilus. They break up, those living on the Lucie
+going to their rooms and the rest back to the yacht, which is
+anchored out further in the deeper water of the bay.
+
+"Some time in the middle of the night her maid, Juanita, finds
+that she is not in her room. Her brother is summoned back from his
+yacht and finds that she has left this pathetic, unfinished
+letter. But otherwise there is no trace of her. Her husband is
+notified and hurries out there, but he can find no clue.
+Meanwhile, Mr. Waldon, in despair, hurries down to the city to
+engage me quietly."
+
+"You remember I told you," suggested Waldon, "that my sister
+hadn't been feeling well for several days. In fact it seemed that
+the sea air wasn't doing her much good, and some one last night
+suggested that she try the mountains."
+
+"Had there been anything that would foreshadow the--er--
+disappearance?" asked Kennedy.
+
+"Only as I say, that for two or three days she seemed to be
+listless, to be sinking by slow and easy stages into a sort of
+vacant, moody state of ill health."
+
+"She had a doctor, I suppose?" I asked.
+
+"Yes, Dr. Jermyn, Tracy's own personal physician came down from
+the city several days ago."
+
+"What did he say?"
+
+"He simply said that it was congestion of the lungs. As far as he
+could see there was no apparent cause for it. I don't think he was
+very enthusiastic about the mountain air idea. The fact is he was
+like a good many doctors under the circumstances, noncommittal--
+wanted her under observation, and all that sort of thing."
+
+"What's your opinion?" I pressed Craig. "Do you think she has run
+away?"
+
+"Naturally, I'd rather not attempt to say yet," Craig replied
+cautiously. "But there are several possibilities. Yes, she might
+have left the houseboat in some other boat, of course. Then there
+is the possibility of accident. It was a hot night. She might have
+been leaning from the window and have lost her balance. I have
+even thought of drugs, that she might have taken something in her
+despondency and have fallen overboard while under the influence of
+it. Then, of course, there are the two deductions that everyone
+has made already--either suicide or murder."
+
+Waldon had evidently been turning something over in his mind.
+
+"There was a wireless outfit aboard the houseboat," he ventured at
+length.
+
+"What of that?" I asked, wondering why he was changing the subject
+so abruptly.
+
+"Why, only this," he replied. "I have been reading about wireless
+a good deal lately, and if the theories of some scientists are
+correct, the wireless age is not without its dangers as well as
+its wonders. I recall reading not long ago of a German professor
+who says there is no essential difference between wireless waves
+and the X-rays, and we know the terrible physical effects of X-
+rays. I believe he estimated that only one three hundred millionth
+part of the electrical energy generated by sending a message from
+one station to another near by is actually used up in transmitting
+the message. The rest is dispersed in the atmosphere. There must
+be a good deal of such stray electrical energy about Seaville.
+Isn't it possible that it might hit some one somewhere who was
+susceptible?"
+
+Kennedy said nothing. Waldon's was at least a novel idea, whether
+it was plausible or not. The only way to test it out, as far as I
+could determine, was to see whether it fitted with the facts after
+a careful investigation of the case itself.
+
+It was still early in the day and the trains were not as crowded
+as they would be later. Consequently our journey was comfortable
+enough and we found ourselves at last at the little vine-covered
+station at Seaville.
+
+One could almost feel that the gay summer colony was in a state of
+subdued excitement. As we left the quaint station and walked down
+the main street to the town wharf where we expected some one would
+be waiting for us, it seemed as if the mysterious disappearance of
+the beautiful Mrs. Edwards had put a damper on the life of the
+place. In the hotels there were knots of people evidently
+discussing the affair, for as we passed we could tell by their
+faces that they recognized us. One or two bowed and would have
+joined us, if Waldon had given any encouragement. But he did not
+stop, and we kept on down the street quickly.
+
+I myself began to feel the spell of mystery about the case as I
+had not felt it among the distractions of the city. Perhaps I
+imagined it, but there even seemed to be something strange about
+the houseboat which we could descry at anchor far down the bay as
+we approached the wharf.
+
+We were met, as Waldon had arranged, by a high-powered runabout,
+the tender to his own yacht, a slim little craft of mahogany and
+brass, driven like an automobile, and capable of perhaps twenty-
+five or thirty miles an hour. We jumped in and were soon skimming
+over the waters of the bay like a skipping stone.
+
+It was evident that Waldon was much relieved at having been able
+to bring assistance, in which he had as much confidence as he
+reposed in Kennedy. At any rate it was something to be nearing the
+scene of action again.
+
+The Lucie was perhaps seventy feet long and a most attractive
+craft, with a hull yachty in appearance and of a type which could
+safely make long runs along the coast, a stanch, seaworthy boat,
+of course without the speed of the regularly designed yacht, but
+more than making up in comfort for those on board what was lost in
+that way. Waldon pointed out with obvious pride his own trim yacht
+swinging gracefully at anchor a half mile or so away.
+
+As we approached the houseboat I looked her over carefully. One of
+the first things I noticed was that there rose from the roof the
+primitive inverted V aerial of a wireless telegraph. I thought
+immediately of the unfinished letter and its contents, and shaded
+my eyes as I took a good look at the powerful transatlantic
+station on the spit of sand perhaps three or four miles distant,
+with its tall steel masts of the latest inverted L type and the
+cluster of little houses below, in which the operators and the
+plant were.
+
+Waldon noticed what I was looking at, and remarked, "It's a
+wonderful station--and well worth a visit, if you have the time--
+one of the most powerful on the coast, I understand."
+
+"How did the Lucie come to be equipped with wireless?" asked Craig
+quickly. "It's a little unusual for a private boat."
+
+"Mr. Edwards had it done when she was built," explained Waldon.
+"His idea was to use it to keep in touch with the stock market on
+trips."
+
+"And it has proved effective?" asked Craig.
+
+"Oh, yes--that is, it was all right last winter when he went on a
+short cruise down in Florida. This summer he hasn't been on the
+boat long enough to use it much."
+
+"Who operates it?"
+
+"He used to hire a licensed operator, although I believe the
+engineer, Pedersen, understands the thing pretty well and could
+use it if necessary."
+
+"Do you think it was Pedersen who used it for Mrs. Edwards?" asked
+Kennedy.
+
+"I really don't know," confessed Waldon. "Pedersen denies
+absolutely that he has touched the thing for weeks. I want you to
+quiz him. I wasn't able to get him to admit a thing."
+
+
+
+
+CHAPTER VIII
+
+THE HOUSEBOAT MYSTERY
+
+
+We had by this time swung around to the side of the houseboat. I
+realized as we mounted the ladder that the marine gasoline engine
+had materially changed the old-time houseboat from a mere scow or
+barge with a low flat house on it, moored in a bay or river, and
+only with difficulty and expense towed from one place to another.
+Now the houseboat was really a fair-sized yacht.
+
+The Lucie was built high in order to give plenty of accommodation
+for the living quarters. The staterooms, dining rooms and saloon
+were really rooms, with seven or eight feet of head room, and
+furnished just as one would find in a tasteful and expensive
+house.
+
+Down in the hull, of course, was the gasoline motor which drove
+the propeller, so that when the owner wanted a change of scene all
+that was necessary was to get up anchor, start the motor and
+navigate the yacht-houseboat to some other harbor.
+
+Edwards himself met us on the deck. He was a tall man, with a red
+face, a man of action, of outdoor life, apparently a hard worker
+and a hard player. It was quite evident that he had been waiting
+for the return of Waldon anxiously.
+
+"You find us considerably upset, Professor Kennedy," he greeted
+Craig, as his brother-in-law introduced us.
+
+Edwards turned and led the way toward the saloon. As he entered
+and bade us be seated in the costly cushioned wicker chairs I
+noticed how sumptuously it was furnished, and particularly its
+mechanical piano, its phonograph and the splendid hardwood floor
+which seemed to invite one to dance in the cool breeze that
+floated across from one set of open windows to the other. And yet
+in spite of everything, there was that indefinable air of
+something lacking, as in a house from which the woman is gone,
+
+"You were not here last night, I understand," remarked Kennedy,
+taking in the room at a glance.
+
+"Unfortunately, no," replied Edwards, "Business has kept me with
+my nose pretty close to the grindstone this summer. Waldon called
+me up in the middle of the night, however, and I started down in
+my car, which enabled me to get here before the first train. I
+haven't been able to do a thing since I got here except just wait-
+-wait--wait. I confess that I don't know what else to do. Waldon
+seemed to think we ought to have some one down here--and I guess
+he was right. Anyhow, I'm glad to see you."
+
+I watched Edwards keenly. For the first time I realized that I had
+neglected to ask Waldon whether he had seen the unfinished letter.
+The question was unnecessary. It was evident that he had not.
+
+"Let me see, Waldon, if I've got this thing straight," Edwards
+went on, pacing restlessly up and down the saloon. "Correct me if
+I haven't. Last night, as I understand it, there was a sort of
+little family party here, you and Miss Verrall and your mother
+from the Nautilus, and Mrs. Edwards and Dr. Jermyn."
+
+"Yes," replied Waldon with, I thought, a touch of defiance at the
+words "family party." He paused as if he would have added that the
+Nautilus would have been more congenial, anyhow, then added, "We
+danced a little bit, all except Lucie. She said she wasn't feeling
+any too well."
+
+Edwards had paused by the door. "If you'll excuse me a minute," he
+said, "I'll call Jermyn and Mrs. Edwards' maid, Juanita. You ought
+to go over the whole thing immediately, Professor Kennedy."
+
+"Why didn't you say anything about the letter to him?" asked
+Kennedy under his breath.
+
+"What was the use?" returned Waldon. "I didn't know how he'd take
+it. Besides, I wanted your advice on the whole thing. Do you want
+to show it to him?"
+
+"Perhaps it's just as well," ruminated Kennedy. "It may be
+possible to clear the thing up without involving anybody's name.
+At any rate, some one is coming down the passage this way."
+
+Edwards entered with Dr. Jermyn, a clean-shaven man, youthful in
+appearance, yet approaching middle age. I had heard of him before.
+He had studied several years abroad and had gained considerable
+reputation since his return to America.
+
+Dr. Jermyn shook hands with us cordially enough, made some passing
+comment on the tragedy, and stood evidently waiting for us to
+disclose our hands.
+
+"You have been Mrs. Edwards' physician for some time, I believe?"
+queried Kennedy, fencing for an opening.
+
+"Only since her marriage," replied the doctor briefly.
+
+"She hadn't been feeling well for several days, had she?" ventured
+Kennedy again.
+
+"No," replied Dr. Jermyn quickly. "I doubt whether I can add much
+to what you already know. I suppose Mr. Waldon has told you about
+her illness. The fact is, I suppose her maid Juanita will be able
+to tell you really more than I can."
+
+I could not help feeling that Dr. Jermyn showed a great deal of
+reluctance in talking.
+
+"You have been with her several days, though, haven't you?"
+
+"Four days, I think. She was complaining of feeling nervous and
+telegraphed me to come down here. I came prepared to stay over
+night, but Mr. Edwards happened to run down that day, too, and he
+asked me if I wouldn't remain longer. My practice in the summer is
+such that I can easily leave it with my assistant in the city, so
+I agreed. Really, that is about all I can say. I don't know yet
+what was the matter with Mrs. Edwards, aside from the nervousness
+which seemed to be of some time standing."
+
+He stood facing us, thoughtfully stroking his chin, as a very
+pretty and petite maid nervously entered and stood facing us in
+the doorway.
+
+"Come in, Juanita," encouraged Edwards. "I want you to tell these
+gentlemen just what you told me about discovering that Madame had
+gone--and anything else that you may recall now."
+
+"It was Juanita who discovered that Madame was gone, you know,"
+put in Waldon.
+
+"How did you discover it?" prompted Craig.
+
+"It was very hot," replied the maid, "and often on hot nights I
+would come in and fan Madame since she was so wakeful. Last night
+I went to the door and knocked. There was no reply. I called to
+her, 'Madame, madame.' Still there was no answer. The worst I
+supposed was that she had fainted. I continued to call."
+
+"The door was locked?" inquired Kennedy.
+
+"Yes, sir. My call aroused the others on the boat. Dr. Jermyn came
+and he broke open the door with his shoulder. But the room was
+empty. Madame was gone."
+
+"How about the windows?" asked Kennedy.
+
+"Open. They were always open these nights. Sometimes Madame would
+sit by the window when there was not much breeze."
+
+"I should like to see the room," remarked Craig, with an inquiring
+glance at Edwards.
+
+"Certainly," he answered, leading the way down a corridor.
+
+Mrs. Edwards' room was on the starboard side, with wide windows
+instead of portholes. It was furnished magnificently and there was
+little about it that suggested the nautical, except the view from
+the window.
+
+"The bed had not been slept in," Edwards remarked as we looked
+about curiously.
+
+Kennedy walked over quickly to the wide series of windows before
+which was a leather-cushioned window seat almost level with the
+window, several feet above the level of the water. It was by this
+window, evidently, that Juanita meant that Mrs. Edwards often sat.
+It was a delightful position, but I could readily see that it
+would be comparatively easy for anyone accidentally or purposely
+to fall.
+
+"I think myself," Waldon remarked to Kennedy, "that it must have
+been from the open window that she made her way to the outside. It
+seems that all agree that the door was locked, while the window
+was wide open."
+
+"There had been no sound--no cry to alarm you?" shot out Kennedy
+suddenly to Juanita.
+
+"No, sir, nothing. I could not sleep myself, and I thought of
+Madame."
+
+"You heard nothing?" he asked of Dr. Jermyn.
+
+"Nothing until I heard the maid call," he replied briefly.
+
+Mentally I ran over again Kennedy's first list of possibilities--
+taken off by another boat, accident, drugs, suicide, murder.
+
+Was there, I asked myself, sufficient reason for suicide? The
+letter seemed to me to show too proud a spirit for that. In fact
+the last sentence seemed to show that she was contemplating the
+surest method of revenge, rather than surrender. As for accident,
+why should a person fall overboard from a large houseboat into a
+perfectly calm harbor? Then, too, there had been no outcry.
+Somehow, I could not seem to fit any of the theories in with the
+facts. Evidently it was like many another case, one in which we,
+as yet, had insufficient data for a conclusion.
+
+Suddenly I recalled the theory that Waldon himself had advanced
+regarding the wireless, either from the boat itself or from the
+wireless station. For the moment, at least, it seemed plausible
+that she might have been seated at the window, that she might have
+been affected by escaped wireless, or by electrolysis. I knew that
+some physicians had described a disease which they attributed to
+wireless, a sort of anemia with a marked diminution in the number
+of red corpuscles in the blood, due partly to the over
+etherization of the air by reason of the alternating currents used
+to generate the waves.
+
+"I should like now to inspect the little wireless plant you have
+here on the Lucie," remarked Kennedy. "I noticed the mast as we
+were approaching a few minutes ago."
+
+I had turned at the sound of his voice in time to catch Edwards
+and Dr. Jermyn eyeing each other furtively. Did they know about
+the letter, after all, I wondered? Was each in doubt about just
+how much the other knew?
+
+There was no time to pursue these speculations. "Certainly,"
+agreed Mr. Edwards promptly, leading the way.
+
+Kennedy seemed keenly interested in inspecting the little wireless
+plant, which was of a curious type and not exactly like any that I
+had seen before.
+
+"Wireless apparatus," he remarked, as he looked it over, "is
+divided into three parts, the source of power whether battery or
+dynamo, the making and sending of wireless waves, including the
+key, spark, condenser and tuning coil, and the receiving
+apparatus, head telephones, antennae, ground and detector."
+
+Pedersen, the engineer, came in while we were looking the plant
+over, but seemed uncommunicative to all Kennedy's efforts to
+engage him in conversation.
+
+"I see," remarked Kennedy, "that it is a very compact system with
+facilities for a quick change from one wave length to another."
+
+"Yes," grunted Pedersen, as averse to talking, evidently, as
+others on the Lucie.
+
+"Spark gap, quenched type," I heard Kennedy mutter almost to
+himself, with a view to showing Pedersen that he knew something
+about it. "Break system relay--operator can overhear any
+interference while transmitting--transformation by a single throw
+of a six-point switch which tunes the oscillating and open
+circuits to resonance. Very clever--very efficient. By the way,
+Pedersen, are you the only person aboard who can operate this?"
+
+"How should I know?" he answered almost surlily.
+
+"You ought to know, if anybody," answered Kennedy unruffled. "I
+know that it has been operated within the past few days."
+
+Pedersen shrugged his shoulders. "You might ask the others
+aboard," was all he said. "Mr. Edwards pays me to operate it only
+for himself, when he has no other operator."
+
+Kennedy did not pursue the subject, evidently from fear of saying
+too much just at present.
+
+"I wonder if there is anyone else who could have operated it,"
+said Waldon, as we mounted again to the deck.
+
+"I don't know," replied Kennedy, pausing on the way up. "You
+haven't a wireless on the Nautilus, have you?"
+
+Waldon shook his head. "Never had any particular use for it
+myself," he answered.
+
+"You say that Miss Verrall and her mother have gone back to the
+city?" pursued Kennedy, taking care that as before the others were
+out of earshot.
+
+"Yes."
+
+"I'd like to stay with you tonight, then," decided Kennedy. "Might
+we go over with you now? There doesn't seem to be anything more I
+can do here, unless we get some news about Mrs. Edwards."
+
+Waldon seemed only too glad to agree, and no one on the Lucie
+insisted on our staying.
+
+We arrived at the Nautilus a few minutes later, and while we were
+lunching Kennedy dispatched the tender to the Marconi station with
+a note.
+
+It was early in the afternoon when the tender returned with
+several packages and coils of wire. Kennedy immediately set to
+work on the Nautilus stretching out some of the wire.
+
+"What is it you are planning?" asked Waldon, to whom every action
+of Kennedy seemed to be a mystery of the highest interest.
+
+"Improvising my own wireless," he replied, not averse to talking
+to the young man to whom he seemed to have taken a fancy. "For
+short distances, you know, it isn't necessary to construct an
+aerial pole or even to use outside wires to receive messages. All
+that is needed is to use just a few wires stretched inside a room.
+The rest is just the apparatus."
+
+I was quite as much interested as Waldon. "In wireless," he went
+on, "the signals are not sent in one direction, but in all, so
+that a person within range of the ethereal disturbance can get
+them if only he has the necessary receiving apparatus. This
+apparatus need not be so elaborate and expensive as used to be
+thought needful if a sensitive detector is employed, and I have
+sent over to the station for a new piece of apparatus which I knew
+they had in almost any Marconi station. Why, I've got wireless
+signals using only twelve feet of number eighteen copper wire
+stretched across a room and grounded with a water pipe. You might
+even use a wire mattress on an iron bedstead."
+
+"Can't they find out by--er, interference?" I asked, repeating the
+term I had so often heard.
+
+Kennedy laughed. "No, not for radio apparatus which merely
+receives radiograms and is not equipped for sending. I am setting
+up only one side of a wireless outfit here. All I want to do is to
+hear what is being said. I don't care about saying anything."
+
+He unwrapped another package which had been loaned to him by the
+radio station and we watched him curiously as he tested it and set
+it up. Some parts of it I recognized such as the very sensitive
+microphone, and another part I could have sworn was a phonograph
+cylinder, though Craig was so busy testing his apparatus that now
+we could not ask questions.
+
+It was late in the afternoon when he finished, and we had just
+time to run up to the dock at Seaville and stop off at the Lucie
+to see if anything had happened in the intervening hours before
+dinner. There was nothing, except that I found time to file a
+message to the Star and meet several fellow newspaper men who had
+been sent down by other papers on the chance of picking up a good
+story.
+
+We had the Nautilus to ourselves, and as she was a very
+comfortable little craft, we really had a very congenial time, a
+plunge over her side, a good dinner, and then a long talk out on
+deck under the stars, in which we went over every phase of the
+case. As we discussed it, Waldon followed keenly, and it was quite
+evident from his remarks that he had come to the conclusion that
+Dr. Jermyn at least knew more than he had told about the case.
+
+Still, the day wore away with no solution yet of the mystery.
+
+
+
+
+CHAPTER IX
+
+THE RADIO DETECTIVE
+
+
+It was early the following morning when a launch drew up beside
+the Nautilus. In it were Edwards and Dr. Jermyn, wildly excited.
+
+"What's the matter?" called out Waldon.
+
+"They--they have found the body," Edwards blurted out.
+
+Waldon paled and clutched the rail. He had thought the world of
+his sister, and not until the last moment had he given up hope
+that perhaps she might be found to have disappeared in some other
+way than had become increasingly evident.
+
+"Where?" cried Kennedy. "Who?"
+
+"Over on Ten Mile Beach," answered Edwards. "Some fishermen who
+had been out on a cruise and hadn't heard the story. They took the
+body to town, and there it was recognized. They sent word out to
+us immediately."
+
+Waldon had already spun the engine of his tender, which was about
+the fastest thing afloat about Seaville, had taken Edwards over,
+and we were off in a cloud of spray, the nose of the boat many
+inches above the surface of the water.
+
+In the little undertaking establishment at Seaville lay the body
+of the beautiful young matron about whom so much anxiety had been
+felt. I could not help thinking what an end was this for the
+incomparable beauty. At the very height of her brief career the
+poor little woman's life had been suddenly snuffed out. But by
+what? The body had been found, but the mystery had been far from
+solved.
+
+As Kennedy bent over the body, I heard him murmur to himself, "She
+had everything--everything except happiness."
+
+"Was it drowning that caused her death?" asked Kennedy of the
+local doctor, who also happened to be coroner and had already
+arrived on the scene.
+
+The doctor shook his head. "I don't know," he said doubtfully.
+"There was congestion of the lungs--but I--I can't say but what
+she might have been dead before she fell or was thrown into the
+water."
+
+Dr. Jermyn stood on one side, now and then putting in a word, but
+for the most part silent unless spoken to. Kennedy, however, was
+making a most minute examination.
+
+As he turned the beautiful head, almost reverently, he saw
+something that evidently attracted his attention. I was standing
+next to him and, between us, I think we cut off the view of the
+others. There on the back of the neck, carefully, had been smeared
+something transparent, almost skin-like, which had easily escaped
+the attention of the rest.
+
+Kennedy tried to pick it off, but only succeeded in pulling off a
+very minute piece to which the flesh seemed to adhere.
+
+"That's queer," he whispered to me. "Water, naturally, has no
+effect on it, else it would have been washed off long before.
+Walter," he added, "just slip across the street quietly to the
+drug store and get me a piece of gauze soaked with acetone."
+
+As quickly and unostentatiously as I could I did so and handed him
+the wet cloth, contriving at the same time to add Waldon to our
+barrier, for I could see that Kennedy was anxious to be observed
+as little as possible.
+
+"What is it?" I whispered, as he rubbed the transparent skin-like
+stuff off, and dropped the gauze into his pocket.
+
+"A sort of skin varnish," he remarked under his breath,
+"waterproof and so adhesive that it resists pulling off even with
+a knife without taking the cuticle with it."
+
+Beneath, as the skin varnish slowly dissolved under his gentle
+rubbing, he had disclosed several very small reddish spots, like
+little cuts that had been made by means of a very sharp
+instrument. As he did so, he gave them a hasty glance, turned the
+now stony beautiful head straight again, stood up, and resumed his
+talk with the coroner, who was evidently getting more and more
+bewildered by the case.
+
+Edwards, who had completed the arrangements with the undertaker
+for the care of the body as soon as the coroner released it,
+seemed completely unnerved.
+
+"Jermyn," he said to the doctor, as he turned away and hid his
+eyes, "I can't stand this. The undertaker wants some stuff from
+the--er--boat," his voice broke over the name which had been hers.
+"Will you get it for me? I'm going up to a hotel here, and I'll
+wait for you there. But I can't go out to the boat--yet."
+
+"I think Mr. Waldon will be glad to take you out in his tender,"
+suggested Kennedy. "Besides, I feel that I'd like a little fresh
+air as a bracer, too, after such a shock."
+
+"What were those little cuts?" I asked as Waldon and Dr. Jermyn
+preceded us through the crowd outside to the pier.
+
+"Some one," he answered in a low tone, "has severed the
+pneumogastric nerves."
+
+"The pneumogastric nerves?" I repeated.
+
+"Yes, the vagus or wandering nerve, the so-called tenth cranial
+nerve. Unlike the other cranial nerves, which are concerned with
+the special senses or distributed to the skin and muscles of the
+head and neck, the vagus, as its name implies, strays downward
+into the chest and abdomen supplying branches to the throat,
+lungs, heart and stomach and forms an important connecting link
+between the brain and the sympathetic nervous system."
+
+We had reached the pier, and a nod from Kennedy discouraged
+further conversation on the subject.
+
+A few minutes later we had reached the Lucie and gone up over her
+side. Kennedy waited until Jermyn had disappeared into the room of
+Mrs. Edwards to get what the undertaker had desired. A moment and
+he had passed quietly into Dr. Jermyn's own room, followed by me.
+Several quick glances about told him what not to waste time over,
+and at last his eye fell on a little portable case of medicines
+and surgical instruments. He opened it quickly and took out a
+bottle of golden yellow liquid.
+
+Kennedy smelled it, then quickly painted some on the back of his
+hand. It dried quickly, like an artificial skin. He had found a
+bottle of skin varnish in Dr. Jermyn's own medicine chest!
+
+We hurried back to the deck, and a few minutes later the doctor
+appeared with a large package.
+
+"Did you ever hear of coating the skin by a substance which is
+impervious to water, smooth and elastic?" asked Kennedy quietly as
+Waldon's tender sped along back to Seaville.
+
+"Why--er, yes," he said frankly, raising his eyes and looking at
+Craig in surprise. "There have been a dozen or more such
+substances. The best is one which I use, made of pyroxylin, the
+soluble cotton of commerce, dissolved in amyl acetate and acetone
+with some other substances that make it perfectly sterile. Why do
+you ask?"
+
+"Because some one has used a little bit of it to cover a few
+slight cuts on the back of the neck of Mrs. Edwards."
+
+"Indeed?" he said simply, in a tone of mild surprise.
+
+"Yes," pursued Kennedy. "They seem to me to be subcutaneous
+incisions of the neck with a very fine scalpel dividing the two
+great pneumogastric nerves. Of course you know what that would
+mean--the victim would pass away naturally by slow and easy stages
+in three or four days, and all that would appear might be
+congestion of the lungs. They are delicate little punctures and
+elusive nerves to locate, but after all it might be done as
+painlessly, as simply and as safely as a barber might remove some
+dead hairs. A country coroner might easily pass over such evidence
+at an autopsy--especially if it was concealed by skin varnish."
+
+I was surprised at the frankness with which Kennedy spoke, but
+absolutely amazed at the coolness of Jermyn. At first he said
+absolutely nothing. He seemed to be as set in his reticence as he
+had been when we first met.
+
+I watched him narrowly. Waldon, who was driving the boat, had not
+heard what was said, but I had, and I could not conceive how
+anyone could take it so calmly.
+
+Finally Jermyn turned to Kennedy and looked him squarely in the
+eye. "Kennedy," he said slowly, "this is extraordinary--most
+extraordinary," then, pausing, added, "if true."
+
+"There can be no doubt of the truth," replied Kennedy, eyeing Dr.
+Jermyn just as squarely.
+
+"What do you propose to do about it?" asked the doctor.
+
+"Investigate," replied Kennedy simply. "While Waldon takes these
+things up to the undertaker's, we may as well wait here in the
+boat. I want him to stop on the way back for Mr. Edwards. Then we
+shall go out to the Lucie. He must go, whether he likes it or
+not."
+
+It was indeed a most peculiar situation as Kennedy and I sat in
+the tender with Dr. Jermyn waiting for Waldon to return with
+Edwards. Not a word was spoken.
+
+The tenseness of the situation was not relieved by the return of
+Waldon with Edwards. Waldon seemed to realize without knowing just
+what it was, that something was about to happen. He drove his boat
+back to the Lucie again in record time. This was Kennedy's turn to
+be reticent. Whatever it was he was revolving in his mind, he
+answered in scarcely more than monosyllables whatever questions
+were put to him.
+
+"You are not coming aboard?" inquired Edwards in surprise as he
+and Jermyn mounted the steps of the houseboat ladder, and Kennedy
+remained seated in the tender.
+
+"Not yet," replied Craig coolly.
+
+"But I thought you had something to show me. Waldon told me you
+had."
+
+"I think I shall have in a short time," returned Kennedy. "We
+shall be back immediately. I'm just going to ask Waldon to run
+over to the Nautilus for a few minutes. We'll tow back your
+launch, too, in case you need it."
+
+Waldon had cast off obediently.
+
+"There's one thing sure," I remarked. "Jermyn can't get away from
+the Lucie until we return--unless he swims."
+
+Kennedy did not seem to pay much attention to the remark, for his
+only reply was: "I'm taking a chance by this maneuvering, but I
+think it will work out that I am correct. By the way, Waldon, you
+needn't put on so much speed. I'm in no great hurry to get back.
+Half an hour will be time enough."
+
+"Jermyn? What did you mean by Jermyn?" asked Waldon, as we climbed
+to the deck of the Nautilus.
+
+He had evidently learned, as I had, that it was little use to try
+to quiz Kennedy until he was ready to be questioned and had
+decided to try it on me.
+
+I had nothing to conceal and I told him quite fully all that I
+knew. Actually, I believe if Jermyn had been there, it would have
+taken both Kennedy and myself to prevent violence. As it was I had
+a veritable madman to deal with while Kennedy gathered up
+leisurely the wireless outfit he had installed on the deck of
+Waldon's yacht. It was only by telling him that I would certainly
+demand that Kennedy leave him behind if he did not control his
+feelings that I could calm him before Craig had finished his work
+on the yacht.
+
+Waldon relieved himself by driving the tender back at top speed to
+the Lucie, and now it seemed that Kennedy had no objection to
+traveling as fast as the many-cylindered engine was capable of
+going.
+
+As we entered the saloon of the houseboat, I kept close watch over
+Waldon.
+
+Kennedy began by slipping a record on the phonograph in the corner
+of the saloon, then facing us and addressing Edwards particularly.
+
+"You may be interested to know, Mr. Edwards," he said, "that your
+wireless outfit here has been put to a use for which you never
+intended it."
+
+No one said anything, but I am sure that some one in the room then
+for the first time began to suspect what was coming.
+
+"As you know, by the use of an aerial pole, messages may be easily
+received from any number of stations," continued Craig. "Laws,
+rules and regulations may be adopted to shut out interlopers and
+plug busybody ears, but the greater part of whatever is
+transmitted by the Hertzian waves can be snatched down by other
+wireless apparatus.
+
+"Down below, in that little room of yours," went on Craig, "might
+sit an operator with his ear-phone clamped to his head, drinking
+in the news conveyed surely and swiftly to him through the
+wireless signals--plucking from the sky secrets of finance and,"
+he added, leaning forward, "love."
+
+In his usual dramatic manner Kennedy had swung his little audience
+completely with him.
+
+"In other words," he resumed, "it might be used for eavesdropping
+by a wireless wiretapper. Now," he concluded, "I thought that if
+there was any radio detective work being done, I might as well do
+some, too."
+
+He toyed for a moment with the phonograph record. "I have used,"
+he explained, "Marconi's radiotelephone, because in connection
+with his receivers Marconi uses phonographic recorders and on them
+has captured wireless telegraph signals over hundreds of miles.
+
+"He has found that it is possible to receive wireless signals,
+although ordinary records are not loud enough, by using a small
+microphone on the repeating diaphragm and connected with a loud-
+speaking telephone. The chief difficulty was to get a microphone
+that would carry a sufficient current without burning up. There
+were other difficulties, but they have been surmounted and now
+wireless telegraph messages may be automatically recorded and made
+audible."
+
+Kennedy started the phonograph, running it along, stopping it,
+taking up the record at a new point.
+
+"Listen," he exclaimed at length, "there's something interesting,
+the WXY call--Seaville station--from some one on the Lucie only a
+few minutes ago, sending a message to be relayed by Seaville to
+the station at Beach Park. It seems impossible, but buzzing and
+ticking forth is this message from some one off this very
+houseboat. It reads: "Miss Valerie Fox, Beach Park. I am suspected
+of the murder of Mrs. Edwards. I appeal to you to help me. You
+must allow me to tell the truth about the messages I intercepted
+for Mrs. Edwards which passed between yourself on the ocean and
+Mr. Edwards in New York via Seaville. You rejected me and would
+not let me save you. Now you must save me."
+
+Kennedy paused, then added, "The message is signed by Dr. Jermyn!"
+
+At once I saw it all. Jermyn had been the unsuccessful suitor for
+Miss Fox's affections. But before I could piece out the rest of
+the tragic story, Kennedy had started the phonograph record at an
+earlier point which he had skipped for the present.
+
+"Here's another record--a brief one--also to Valerie Fox from the
+houseboat: 'Refuse all interviews. Deny everything. Will see you
+as soon as present excitement dies down.'"
+
+Before Kennedy could finish, Waldon had leaped forward, unable
+longer to control his feelings. If Kennedy had not seized his arm,
+I verily believe he would have cast Dr. Jermyn into the bay into
+which his sister had fallen two nights before in her terribly
+weakened condition.
+
+"Waldon," cried Kennedy, "for God's sake, man--wait! Don't you
+understand? The second message is signed Tracy Edwards."
+
+It came as quite as much a shock of surprise to me as to Waldon.
+
+"Don't you understand?" he repeated. "Your sister first learned
+from Dr. Jermyn what was going on. She moved the Lucie down here
+near Seaville in order to be near the wireless station when the
+ship bearing her rival, Valerie Fox, got in touch with land. With
+the help of Dr. Jermyn she intercepted the wireless messages from
+the Kronprinz to the shore--between her husband and Valerie Fox."
+
+Kennedy was hurrying on now to his irresistible conclusion. "She
+found that he was infatuated with the famous stage beauty, that he
+was planning to marry another, her rival. She accused him of it,
+threatened to defeat his plans. He knew she knew his
+unfaithfulness. Instead of being your sister's murderer, Dr.
+Jermyn was helping her get the evidence that would save both her
+and perhaps win Miss Fox back to himself."
+
+Kennedy had turned sharply on Edwards.
+
+"But," he added, with a glance that crushed any lingering hope
+that the truth had been concealed, "the same night that Dr. Jermyn
+arrived here, you visited your wife. As she slept you severed the
+nerves that meant life or death to her. Then you covered the cuts
+with the preparation which you knew Dr. Jermyn used. You asked him
+to stay, while you went away, thinking that when death came you
+would have a perfect alibi--perhaps a scapegoat. Edwards, the
+radio detective convicts you!"
+
+
+
+
+CHAPTER X
+
+THE CURIO SHOP
+
+
+Edwards crumpled up as Kennedy and I faced him. There was no
+escape. In fact our greatest difficulty was to protect him from
+Waldon.
+
+Kennedy's work in the case was over when we had got Edwards ashore
+and in the hands of the authorities. But mine had just begun and
+it was late when I got my story on the wire for the Star.
+
+I felt pretty tired and determined to make up for it by sleeping
+the next day. It was no use, however.
+
+"Why, what's the matter, Mrs. Northrop?" I heard Kennedy ask as he
+opened our door the next morning, just as I had finished dressing.
+
+He had admitted a young woman, who greeted us with nervous, wide-
+staring eyes.
+
+"It's--it's about Archer," she cried, sinking into the nearest
+chair and staring from one to the other of us.
+
+She was the wife of Professor Archer Northrop, director of the
+archeological department at the university. Both Craig and I had
+known her ever since her marriage to Northrop, for she was one of
+the most attractive ladies in the younger set of the faculty, to
+which Craig naturally belonged. Archer had been of the class below
+us in the university. We had hazed him, and out of the mild hazing
+there had, strangely enough, grown a strong friendship.
+
+I recollected quickly that Northrop, according to last reports,
+had been down in the south of Mexico on an archeological
+expedition. But before I could frame, even in my mind, the natural
+question in a form that would not alarm his wife further, Kennedy
+had it on his lips.
+
+"No bad news from Mitla, I hope?" he asked gently, recalling one
+of the main working stations chosen by the expedition and the
+reported unsettled condition of the country about it. She looked
+up quickly.
+
+"Didn't you know--he--came back from Vera Cruz yesterday?" she
+asked slowly, then added, speaking in a broken tone, "and--he
+seems--suddenly--to have disappeared. Oh, such a terrible night of
+worry! No word--and I called up the museum, but Doctor Bernardo,
+the curator, had gone, and no one answered. And this morning--I
+couldn't stand it any longer--so I came to you."
+
+"You have no idea, I suppose, of anything that was weighing on his
+mind?" suggested Kennedy.
+
+"No," she answered promptly.
+
+In default of any further information, Kennedy did not pursue this
+line of questioning. I could not determine from his face or manner
+whether he thought the matter might involve another than Mrs.
+Northrop, or, perhaps, something connected with the unsettled
+condition of the country from which her husband had just arrived.
+
+"Have you any of the letters that Archer wrote home?" asked Craig,
+at length.
+
+"Yes," she replied eagerly, taking a little packet from her
+handbag. "I thought you might ask that. I brought them."
+
+"You are an ideal client," commented Craig encouragingly, taking
+the letters. "Now, Mrs. Northrop, be brave. Trust me to run this
+thing down, and if you hear anything let me know immediately."
+
+She left us a moment later, visibly relieved.
+
+Scarcely had she gone when Craig, stuffing the letters into his
+pocket unread, seized his hat, and a moment later was striding
+along toward the museum with his habitual rapid, abstracted step
+which told me that he sensed a mystery.
+
+In the museum we met Doctor Bernardo, a man slightly older than
+Northrop, with whom he had been very intimate. He had just arrived
+and was already deeply immersed in the study of some new and
+beautiful colored plates from the National Museum of Mexico City.
+
+"Do you remember seeing Northrop here yesterday afternoon?"
+greeted Craig, without explaining what had happened.
+
+"Yes," he answered promptly. "I was here with him until very late.
+At least, he was in his own room, working hard, when I left."
+
+"Did you see him go?"
+
+"Why--er--no," replied Bernardo, as if that were a new idea. "I
+left him here--at least, I didn't see him go out."
+
+Kennedy tried the door of Northrop's room, which was at the far
+end, in a corner, and communicated with the hall only through the
+main floor of the museum. It was locked. A pass-key from the
+janitor quickly opened it.
+
+Such a sight as greeted us, I shall never forget. There, in his
+big desk-chair, sat Northrop, absolutely rigid, the most horribly
+contorted look on his features that I have ever seen--half of
+pain, half of fear, as if of something nameless.
+
+Kennedy bent over. His hands were cold.
+
+Northrop had been dead at least twelve hours, perhaps longer. All
+night the deserted museum had guarded its terrible secret.
+
+As Craig peered into his face, he saw, in the fleshy part of the
+neck, just below the left ear, a round red mark, with just a drop
+or two of now black coagulated blood in the center. All around we
+could see a vast amount of miscellaneous stuff, partly unpacked,
+partly just opened, and waiting to be taken out of the wrappings
+by the now motionless hands.
+
+"I suppose you are more or less familiar with what Northrop
+brought back?" asked Kennedy of Bernardo, running his eye over the
+material in the room.
+
+"Yes, reasonably," answered Bernardo. "Before the cases arrived
+from the wharf, he told me in detail what he had managed to bring
+up with him."
+
+"I wish, then, that you would look it over and see if there is
+anything missing," requested Craig, already himself busy in going
+over the room for other evidence.
+
+Doctor Bernardo hastily began taking a mental inventory of the
+stuff. While they worked, I tried vainly to frame some theory
+which would explain the startling facts we had so suddenly
+discovered.
+
+Mitla, I knew, was south of the city of Oaxaca, and there, in its
+ruined palaces, was the crowning achievement of the old Zapotec
+kings. No ruins in America were more elaborately ornamented or
+richer in lore for the archeologist.
+
+Northrop had brought up porphyry blocks with quaint grecques and
+much hieroglyphic painting. Already unpacked were half a dozen
+copper axes, some of the first of that particular style that had
+ever been brought to the United States. Besides the sculptured
+stones and the mosaics were jugs, cups, vases, little gods,
+sacrificial stones--enough, almost, to equip a new alcove in the
+museum.
+
+Before Northrop was an idol, a hideous thing on which frogs and
+snakes squatted and coiled. It was a fitting piece to accompany
+the gruesome occupant of the little room in his long, last vigil.
+In fact, it almost sent a shudder over me, and if I had been
+inclined to the superstitious, I should certainly have concluded
+that this was retribution for having disturbed the lares and
+penates of a dead race.
+
+Doctor Bernardo was going over the material a second time. By the
+look on his face, even I could guess that something was missing.
+
+"What is it?" asked Craig, following the curator closely.
+
+"Why," he answered slowly, "there was an inscription--we were
+looking at it earlier in the day--on a small block of porphyry. I
+don't see it."
+
+He paused and went back to his search before we could ask him
+further what he thought the inscription was about.
+
+I thought nothing myself at the time of his reticence, for Kennedy
+had gone over to a window back of Northrop and to the left. It was
+fully twenty feet from the downward slope of the campus there,
+and, as he craned his neck out, he noted that the copper leader of
+the rain pipe ran past it a few feet away.
+
+I, too, looked out. A thick group of trees hid the window from the
+avenue beyond the campus wall, and below us, at a corner of the
+building, was a clump of rhododendrons. As Craig bent over the
+sill, he whipped out a pocket lens.
+
+A moment later he silently handed the glass to me. As nearly as I
+could make out, there were five marks on the dust of the sill.
+
+"Finger-prints!" I exclaimed. "Some one has been clinging to the
+edge of the ledge."
+
+"In that case," Craig observed quietly, "there would have been
+only four prints."
+
+I looked again, puzzled. The prints were flat and well separated.
+
+"No," he added, "not finger-prints--toe-prints."
+
+"Toe-prints?" I echoed.
+
+Before he could reply, Craig had dashed out of the room, around,
+and under the window. There, he was carefully going over the soft
+earth around the bushes below.
+
+"What are you looking for?" I asked, joining him.
+
+"Some one--perhaps two--has been here," he remarked, almost under
+his breath. "One, at least, has removed his shoes. See those shoe-
+prints up to this point? The print of a boot-heel in soft earth
+shows the position and contour of every nail head. Bertillon has
+made a collection of such nails, certain types, sizes, and shapes
+used in certain boots, showing often what country the shoes came
+from. Even the number and pattern are significant. Some factories
+use a fixed number of nails and arrange them in a particular
+manner. I have made my own collection of such prints in this
+country. These were American shoes. Perhaps the clue will not lead
+us anywhere, though, for I doubt whether it was an American foot."
+
+Kennedy continued to study the marks.
+
+"He removed his shoes--either to help in climbing or to prevent
+noise--ah--here's the foot! Strange--see how small it is--and
+broad, how prehensile the toes--almost like fingers. Surely that
+foot could never have been encased in American shoes all its life.
+I shall make plaster casts of these, to preserve later."
+
+He was still scouting about on hands and knees in the dampness of
+the rhododendrons. Suddenly he reached his long arm in among the
+shrubs and picked up a little reed stick. On the end of it was a
+small cylinder of buff brown.
+
+He looked at it curiously, dug his nail into the soft mass, then
+rubbed his nail over the tip of his tongue gingerly.
+
+With a wry face, as if the taste were extremely acrid, he
+moistened his handkerchief and wiped off his tongue vigorously.
+
+"Even that minute particle that was on my nail makes my tongue
+tingle and feel numb," he remarked, still rubbing. "Let us go back
+again. I want to see Bernardo."
+
+"Had he any visitors during the day?" queried Kennedy, as he
+reentered the ghastly little room, while the curator stood
+outside, completely unnerved by the tragedy which had been so
+close to him without his apparently knowing it. Kennedy was
+squeezing out from the little wound on Northrop's neck a few drops
+of liquid on a sterilized piece of glass.
+
+"No; no one," Bernardo answered, after a moment.
+
+"Did you see anyone in the museum who looked suspicious?" asked
+Kennedy, watching Bernardo's face keenly.
+
+"No," he hesitated. "There were several people wandering about
+among the exhibits, of course. One, I recall, late in the
+afternoon, was a little dark-skinned woman, rather good-looking."
+
+"A Mexican?"
+
+"Yes, I should say so. Not of Spanish descent, though. She was
+rather of the Indian type. She seemed to be much interested in the
+various exhibits, asked me several questions, very intelligently,
+too. Really, I thought she was trying to--er--flirt with me."
+
+He shot a glance at Craig, half of confession, half of
+embarrassment.
+
+"And--oh, yes--there was another--a man, a little man, as I
+recall, with shaggy hair. He looked like a Russian to me. I
+remember, because he came to the door, peered around hastily, and
+went away. I thought he might have got into the wrong part of the
+building and went to direct him right--but before I could get out
+into the hall, he was gone. I remember, too, that, as I turned,
+the woman had followed me and soon was asking other questions--
+which, I will admit--I was glad to answer."
+
+"Was Northrop in his room while these people were here?"
+
+"Yes; he had locked the door so that none of the students or
+visitors could disturb him."
+
+"Evidently the woman was diverting your attention while the man
+entered Northrop's room by the window," ruminated Craig, as we
+stood for a moment in the outside doorway.
+
+He had already telephoned to our old friend Doctor Leslie, the
+coroner, to take charge of the case, and now was ready to leave.
+The news had spread, and the janitor of the building was waiting
+to lock the campus door to keep back the crowd of students and
+others.
+
+Our next duty was the painful one of breaking the news to Mrs.
+Northrop. I shall pass it over. Perhaps no one could have done it
+more gently than Kennedy. She did not cry. She was simply dazed.
+Fortunately her mother was with her, had been, in fact, ever since
+Northrop had gone on the expedition.
+
+"Why should anyone want to steal tablets of old Mixtec
+inscriptions?" I asked thoughtfully, as we walked sadly over the
+campus in the direction of the chemistry building. "Have they a
+sufficient value, even on appreciative Fifth Avenue, to warrant
+murder?"
+
+"Well," he remarked, "it does seem incomprehensible. Yet people do
+just such things. The psychologists tell us that there is a
+veritable mania for possessing such curios. However, it is
+possible that there may be some deeper significance in this case,"
+he added, his face puckered in thought.
+
+Who was the mysterious Mexican woman, who the shaggy Russian? I
+asked myself. Clearly, at least, if she existed at all, she was
+one of the millions not of Spanish but of Indian descent in the
+country south of us. As I reasoned it out, it seemed to me as if
+she must have been an accomplice. She could not have got into
+Northrop's room either before or after Doctor Bernardo left. Then,
+too, the toe-and shoe-prints were not hers. But, I figured, she
+certainly had a part in the plot.
+
+While I was engaged in the vain effort to unravel the tragic
+affair by pure reason, Kennedy was at work with practical science.
+
+He began by examining the little dark cylinder on the end of the
+reed. On a piece of the stuff, broken off, he poured a dark liquid
+from a brown-glass bottle. Then he placed it under a microscope.
+
+"Microscopically," he said slowly, "it consists almost wholly of
+minute, clear granules which give a blue reaction with iodine.
+They are starch. Mixed with them are some larger starch granules,
+a few plant cells, fibrous matter, and other foreign particles.
+And then, there is the substance that gives that acrid, numbing
+taste." He appeared to be vacantly studying the floor.
+
+"What do you think it is?" I asked, unable to restrain myself.
+
+"Aconite," he answered slowly, "of which the active principle is
+the deadly poisonous alkaloid, aconitin."
+
+He walked over and pulled down a well-thumbed standard work on
+toxicology, turned the pages, then began to read aloud:
+
+Pure aconitin is probably the most actively poisonous substance
+with which we are acquainted and, if administered hypodermically,
+the alkaloid is even more powerfully poisonous than when taken by
+the mouth.
+
+As in the case of most of the poisonous alkaloids, aconitin does
+not produce any decidedly characteristic post-mortem appearances.
+There is no way to distinguish it from other alkaloids, in fact,
+no reliable chemical test. The physiological effects before death
+are all that can be relied on.
+
+Owing to its exceeding toxic nature, the smallness of the dose
+required to produce death, and the lack of tests for recognition,
+aconitin possesses rather more interest in legal medicine than
+most other poisons.
+
+It is one of the few substances which, in the present state of
+toxicology, might be criminally administered and leave no positive
+evidence of the crime. If a small but fatal dose of the poison
+were to be given, especially if it were administered
+hypodermically, the chances of its detection in the body after
+death would be practically none.
+
+
+
+
+CHAPTER XI
+
+THE "PILLAR OF DEATH"
+
+
+I was looking at him fixedly as the diabolical nature of what must
+have happened sank into my mind. Here was a poison that defied
+detection. I could see by the look on Craig's face that that
+problem, alone, was enough to absorb his attention. He seemed
+fully to realize that we had to deal with a criminal so clever
+that he might never be brought to justice.
+
+An idea flashed over me.
+
+"How about the letters?" I suggested.
+
+"Good, Walter!" he exclaimed.
+
+He untied the package which Mrs. Northrop had given him and
+glanced quickly over one after another of the letters.
+
+"Ah!" he exclaimed, fairly devouring one dated at Mitla. "Listen--
+it tells about Northrop's work and goes on:
+
+"'I have been much interested in a cavern, or subterraneo, here,
+in the shape of a cross, each arm of which extends for some twelve
+feet underground. In the center it is guarded by a block of stone
+popularly called "the Pillar of Death." There is a superstition
+that whoever embraces it will die before the sun goes down.
+
+"'From the subterraneo is said to lead a long, underground passage
+across the court to another subterranean chamber which is full of
+Mixtec treasure. Treasure hunters have dug all around it, and it
+is said that two old Indians, only, know of the immense amount of
+buried gold and silver, but that they will not reveal it.'"
+
+I started up. Here was the missing link which I had been waiting
+for.
+
+"There, at least, is the motive," I blurted out. "That is why
+Bernardo was so reticent. Northrop, in his innocence of heart, had
+showed him that inscription."
+
+Kennedy said nothing as he finally tied up the little packet of
+letters and locked it in his safe. He was not given to hasty
+generalizations; neither was he one who clung doggedly to a
+preconceived theory.
+
+It was still early in the afternoon. Craig and I decided to drop
+into the museum again in order to see Doctor Bernardo. He was not
+there and we sat down to wait.
+
+Just then the letter box in the door clicked. It was the postman
+on his rounds. Kennedy walked over and picked up the letter.
+
+The postmark bore the words, "Mexico City," and a date somewhat
+later than that on which Northrop had left Vera Cruz. In the lower
+corner, underscored, were the words, "Personal--Urgent."
+
+"I'd like to know what is in that," remarked Craig, turning it
+over and over.
+
+He appeared to be considering something, for he rose suddenly and
+shoved the letter into his pocket.
+
+I followed, and a few moments later, across the campus in his
+laboratory, he was working quickly over an X-ray apparatus. He had
+placed the letter in it.
+
+"These are what are known as 'low' tubes," he explained. "They
+give out 'soft rays.'" He continued to work for a few moments,
+then handed me the letter.
+
+"Now, Walter," he said, "if you will just hurry back to the museum
+and replace that letter, I think I will have something that will
+astonish you--though whether it will have any bearing on the case,
+remains to be seen."
+
+"What is it?" I asked, a few minutes later, when I had rejoined
+him, after returning the letter. He was poring intently over what
+looked like a negative.
+
+"The possibility of reading the contents of documents inclosed in
+a sealed envelope," he replied, still studying the shadowgraph
+closely, "has already been established by the well-known English
+scientist, Doctor Hall Edwards. He has been experimenting with the
+method of using X-rays recently discovered by a German scientist,
+by which radiographs of very thin substances, such as a sheet of
+paper, a leaf, an insect's body, may be obtained. These thin
+substances through which the rays used formerly to pass without
+leaving an impression, can now be radiographed."
+
+I looked carefully as he traced out something on the negative. On
+it was easily possible, following his guidance, to read the words
+inscribed on the sheet of paper inside. So admirably defined were
+all the details that even the gum on the envelope and the edges of
+the sheet of paper inside the envelope could be distinguished.
+
+"Any letter written with ink having a mineral basis can be
+radiographed," added Craig. "Even when the sheet is folded in the
+usual way, it is possible by taking a radiograph stereoscopically,
+to distinguish the writing, every detail standing out in relief.
+Besides, it can be greatly magnified, which aids in deciphering it
+if it is indistinct or jumbled up. Some of it looks like mirror
+writing. Ah," he added, "here's something interesting!"
+
+Together we managed to trace out the contents of several
+paragraphs, of which the significant parts were as follows:
+
+ I am expecting that my friend Senora Herreria will be in New York
+by the time you receive this, and should she call on you, I know
+you will accord her every courtesy. She has been in Mexico City
+for a few days, having just returned from Mitla, where she met
+Professor Northrop. It is rumored that Professor Northrop has
+succeeded in smuggling out of the country a very important stone
+bearing an inscription which, I understand, is of more than
+ordinary interest. I do not know anything definite about it, as
+Senora Herreria is very reticent on the matter, but depend on you
+to find out if possible and let me know of it.
+
+According to the rumors and the statements of the senora, it seems
+that Northrop has taken an unfair advantage of the situation down
+in Oaxaca, and I suppose she and others who know about the
+inscription feel that it is really the possession of the
+government.
+
+You will find that the senora is an accomplished antiquarian and
+scholar. Like many others down here just now, she has a high
+regard for the Japanese. As you know, there exists a natural
+sympathy between some Mexicans and Japanese, owing to what is
+believed to be a common origin of the two races.
+
+In spite of the assertions of many to the contrary, there is
+little doubt left in the minds of students that the Indian races
+which have peopled Mexico were of Mongolian stock. Many words in
+some dialects are easily understood by Chinese immigrants. A
+secretary of the Japanese legation here was able recently to
+decipher old Mixtec inscriptions found in the ruins of Mitla.
+
+Senora Herreria has been much interested in establishing the
+relationship and, I understand, is acquainted with a Japanese
+curio dealer in New York who recently visited Mexico for the same
+purpose. I believe that she wishes to collaborate with him on a
+monograph on the subject, which is expected to have a powerful
+effect on the public opinion both here and at Tokyo.
+
+In regard to the inscription which Northrop has taken with him, I
+rely on you to keep me informed. There seems to be a great deal of
+mystery connected with it, and I am simply hazarding a guess as to
+its nature. If it should prove to be something which might
+interest either the Japanese or ourselves, you can see how
+important it may be, especially in view of the forthcoming mission
+of General Francisco to Tokyo.
+
+Very sincerely yours,
+
+DR. EMILIO SANCHEZ, Director.
+
+"Bernardo is a Mexican," I exclaimed, as Kennedy finished reading,
+"and there can be no doubt that the woman he mentioned was this
+Senora Herreria."
+
+Kennedy said nothing, but seemed to be weighing the various
+paragraphs in the letter.
+
+"Still," I observed, "so far, the only one against whom we have
+any direct suspicion in the case is the shaggy Russian, whoever he
+is."
+
+"A man whom Bernardo says looked like a Russian," corrected Craig.
+
+He was pacing the laboratory restlessly.
+
+"This is becoming quite an international affair," he remarked
+finally, pausing before me, his hat on. "Would you like to relax
+your mind by a little excursion among the curio shops of the city?
+I know something about Japanese curios--more, perhaps, than I do
+of Mexican. It may amuse us, even if it doesn't help in solving
+the mystery. Meanwhile, I shall make arrangements for shadowing
+Bernardo. I want to know just how he acts after he reads that
+letter."
+
+He paused long enough to telephone his instructions to an uptown
+detective agency which could be depended on for such mere routine
+work, then joined me with the significant remark: "Blood is
+thicker than water, anyhow, Walter. Still, even if the Mexicans
+are influenced by sentiment, I hardly think that would account for
+the interest of our friends from across the water in the matter."
+
+I do not know how many of the large and small curio shops of the
+city we visited that afternoon. At another time, I should have
+enjoyed the visits immensely, for anyone seeking articles of
+beauty will find the antique shops of Fifth and Fourth Avenues and
+the side streets well worth visiting.
+
+We came, at length, to one, a small, quaint, dusty rookery, down
+in a basement, entered almost directly from the street. It bore
+over the door a little gilt sign which read simply, "Sato's."
+
+As we entered, I could not help being impressed by the wealth of
+articles in beautiful cloisonne enamel, in mother-of-pearl,
+lacquer, and champleve. There were beautiful little koros, or
+incense burners, vases, and teapots. There were enamels incrusted,
+translucent, and painted, works of the famous Namikawa, of Kyoto,
+and Namikawa, of Tokyo. Satsuma vases, splendid and rare examples
+of the potter's art, crowded gorgeously embroidered screens
+depicting all sorts of brilliant scenes, among others the sacred
+Fujiyama rising in the stately distance. Sato himself greeted us
+with a ready smile and bow.
+
+"I am just looking for a few things to add to my den," explained
+Kennedy, adding, "nothing in particular, but merely whatever
+happens to strike my fancy."
+
+"Surely, then, you have come to the right shop," greeted Sato. "If
+there is anything that interests you, I shall be glad to show it."
+
+"Thank you," replied Craig. "Don't let me trouble you with your
+other customers. I will call on you if I see anything."
+
+For several minutes, Craig and I busied ourselves looking about,
+and we did not have to feign interest, either.
+
+"Often things are not as represented," he whispered to me, after a
+while, "but a connoiseur can tell spurious goods. These are the
+real thing, mostly."
+
+"Not one in fifty can tell the difference," put in the voice of
+Sato, at his elbow.
+
+"Well, you see I happen to know," Craig replied, not the least
+disconcerted. "You can't always be too sure."
+
+A laugh and a shrug was Sato's answer. "It's well all are not so
+keen," he said, with a frank acknowledgment that he was not above
+sharp practices.
+
+I glanced now and then at the expressionless face of the curio
+dealer. Was it merely the natural blankness of his countenance
+that impressed me, or was there, in fact, something deep and dark
+hidden in it, something of "East is East and West is West" which I
+did not and could not understand? Craig was admiring the bronzes.
+He had paused before one, a square metal fire-screen of odd
+design, with the title on a card, "Japan Gazing at the World."
+
+It represented Japan as an eagle, with beak and talons of
+burnished gold, resting on a rocky island about which great waves
+dashed. The bird had an air of dignity and conscious pride in its
+strength, as it looked out at the world, a globe revolving in
+space.
+
+"Do you suppose there is anything significant in that?" I asked,
+pointing to the continent of North America, also in gold and
+prominently in view.
+
+"Ah, honorable sir," answered Sato, before Kennedy could reply,
+"the artist intended by that to indicate Japan's friendliness for
+America and America's greatness."
+
+He was inscrutable. It seemed as if he were watching our every
+move, and yet it was done with a polite cordiality that could not
+give offense.
+
+Behind some bronzes of the Japanese Hercules destroying the demons
+and other mythical heroes was a large alcove, or tokonoma,
+decorated with peacock, stork, and crane panels. Carvings and
+lacquer added to the beauty of it. A miniature chrysanthemum
+garden heightened the illusion. Carved hinoki wood framed the
+panels, and the roof was supported by columns in the old Japanese
+style, the whole being a compromise between the very simple and
+quiet and the polychromatic. The dark woods, the lanterns, the
+floor tiles of dark red, and the cushions of rich gold and yellow
+were most alluring. It had the genuine fascination of the Orient.
+
+"Will the gentlemen drink a little sake?" Sato asked politely.
+
+Craig thanked him and said that we would.
+
+"Otaka!" Sato called.
+
+A peculiar, almost white-skinned attendant answered, and a moment
+later produced four cups and poured out the rice brandy, taking
+his own quietly, apart from us. I watched him drink, curiously. He
+took the cup; then, with a long piece of carved wood, he dipped
+into the sake, shaking a few drops on the floor to the four
+quarters. Finally, with a deft sweep, he lifted his heavy mustache
+with the piece of wood and drank off the draft almost without
+taking breath.
+
+He was a peculiar man of middle height, with a shock of dark,
+tough, woolly hair, well formed and not bad-looking, with a robust
+general physique, as if his ancestors had been meat eaters. His
+forehead was narrow and sloped backward; the cheekbones were
+prominent; nose hooked, broad and wide, with strong nostrils;
+mouth large, with thick lips, and not very prominent chin. His
+eyes were perhaps the most noticeable feature. They were dark
+gray, almost like those of a European.
+
+As Otaka withdrew with the empty cups, we rose to continue our
+inspection of the wonders of the shop. There were ivories of all
+descriptions. Here was a two-handled sword, with a very large
+ivory handle, a weirdly carved scabbard, and wonderful steel
+blade. By the expression of Craig's face, Sato knew that he had
+made a sale.
+
+Craig had been rummaging among some warlike instruments which
+Sato, with the instincts of a true salesman, was now displaying,
+and had picked up a bow. It was short, very strong, and made of
+pine wood. He held it horizontally and twanged the string. I
+looked up in time to catch a pleased expression on the face of
+Otaka.
+
+"Most people would have held it the other way," commented Sato.
+
+Craig said nothing, but was examining an arrow, almost twenty
+inches long and thick, made of cane, with a point of metal very
+sharp but badly fastened. He fingered the deep blood groove in the
+scooplike head of the arrow and looked at it carefully.
+
+"I'll take that," he said, "only I wish it were one with the
+regular reddish-brown lump in it."
+
+"Oh, but, honorable sir," apologized Sato, "the Japanese law
+prohibits that, now. There are few of those, and they are very
+valuable."
+
+"I suppose so," agreed Craig. "This will do, though. You have a
+wonderful shop here, Sato. Some time, when I feel richer, I mean
+to come in again. No, thank you, you need not send them; I'll
+carry them."
+
+We bowed ourselves out, promising to come again when Sato received
+a new consignment from the Orient which he was expecting.
+
+"That other Jap is a peculiar fellow," I observed, as we walked
+along uptown again.
+
+"He isn't a Jap," remarked Craig. "He is an Ainu, one of the
+aborigines who have been driven northward into the island of
+Yezo."
+
+"An Ainu?" I repeated.
+
+"Yes. Generally thought, now, to be a white race and nearer of kin
+to Europeans than Asiatics. The Japanese have pushed them
+northward and are now trying to civilize them. They are a dirty,
+hairy race, but when they are brought under civilizing influences
+they adapt themselves to their environment and make very good
+servants. Still, they are on about the lowest scale of humanity."
+
+"I thought Otaka was very mild," I commented.
+
+"They are a most inoffensive and peaceable people usually," he
+answered, "good-natured and amenable to authority. But they become
+dangerous when driven to despair by cruel treatment. The Japanese
+government is very considerate of them--but not all Japanese are."
+
+
+
+
+CHAPTER XII
+
+THE ARROW POISON
+
+
+Far into the night Craig was engaged in some very delicate and
+minute microscopic work in the laboratory.
+
+We were about to leave when there was a gentle tap on the door.
+Kennedy opened it and admitted a young man, the operative of the
+detective agency who had been shadowing Bernardo. His report was
+very brief, but, to me at least, significant. Bernardo, on his
+return to the museum, had evidently read the letter, which had
+agitated him very much, for a few moments later he hurriedly left
+and went downtown to the Prince Henry Hotel. The operative had
+casually edged up to the desk and overheard whom he asked for. It
+was Senora Herreria. Once again, later in the evening, he had
+asked for her, but she was still out.
+
+It was quite early the next morning, when Kennedy had resumed his
+careful microscopic work, that the telephone bell rang, and he
+answered it mechanically. But a moment later a look of intense
+surprise crossed his face.
+
+"It was from Doctor Leslie," he announced, hanging up the receiver
+quickly. "He has a most peculiar case which he wants me to see--a
+woman."
+
+Kennedy called a cab, and, at a furious pace, we dashed across the
+city and down to the Metropolitan Hospital, where Doctor Leslie
+was waiting. He met us eagerly and conducted us to a little room
+where, lying motionless on a bed, was a woman.
+
+She was a striking-looking woman, dark of hair and skin, and in
+life she must have been sensuously attractive. But now her face
+was drawn and contorted--with the same ghastly look that had been
+on the face of Northrop.
+
+"She died in a cab," explained Doctor Leslie, "before they could
+get her to the hospital. At first they suspected the cab driver.
+But he seems to have proved his innocence. He picked her up last
+night on Fifth Avenue, reeling--thought she was intoxicated. And,
+in fact, he seems to have been right. Our tests have shown a great
+deal of alcohol present, but nothing like enough to have had such
+a serious effect."
+
+"She told nothing of herself?" asked Kennedy.
+
+"No; she was pretty far gone when the cabby answered her signal.
+All he could get out of her was a word that sounded like 'Curio-
+curio.' He says she seemed to complain of something about her
+mouth and head. Her face was drawn and shrunken; her hands were
+cold and clammy, and then convulsions came on. He called an
+ambulance, but she was past saving when it arrived. The numbness
+seemed to have extended over all her body; swallowing was
+impossible; there was entire loss of her voice as well as sight,
+and death took place by syncope."
+
+"Have you any clue to the cause of her death?" asked Craig.
+
+"Well, it might have been some trouble with her heart, I suppose,"
+remarked Doctor Leslie tentatively.
+
+"Oh, she looks strong that way. No, hardly anything organic."
+
+"Well, then I thought she looked like a Mexican," went on Doctor
+Leslie. "It might be some new tropical disease. I confess I don't
+know. The fact is," he added, lowering his voice, "I had my own
+theory about it until a few moments ago. That was why I called
+you."
+
+"What do you mean?" asked Craig, evidently bent on testing his own
+theory by the other's ignorance.
+
+Doctor Leslie made no answer immediately, but raised the sheet
+which covered her body and disclosed, in the fleshy part of the
+upper arm, a curious little red swollen mark with a couple of
+drops of darkened blood.
+
+"I thought at first," he added, "that we had at last a genuine
+'poisoned needle' case. You see, that looked like it. But I have
+made all the tests for curare and strychnin without results."
+
+At the mere suggestion, a procession of hypodermic-needle and
+white-slavery stories flashed before me.
+
+"But," objected Kennedy, "clearly this was not a case of
+kidnaping. It is a case of murder. Have you tested for the
+ordinary poisons?"
+
+Doctor Leslie shook his head. "There was no poison," he said,
+"absolutely none that any of our tests could discover."
+
+Kennedy bent over and squeezed out a few drops of liquid from the
+wound on a microscope slide, and covered them.
+
+"You have not identified her yet," he added, looking up. "I think
+you will find, Leslie, that there is a Senora Herreria registered
+at the Prince Henry who is missing, and that this woman will agree
+with the description of her. Anyhow, I wish you would look it up
+and let me know."
+
+Half an hour later, Kennedy was preparing to continue his studies
+with the microscope when Doctor Bernardo entered. He seemed most
+solicitous to know what progress was being made on the case, and,
+although Kennedy did not tell much, still he did not discourage
+conversation on the subject.
+
+When we came in the night before, Craig had unwrapped and tossed
+down the Japanese sword and the Ainu bow and arrow on a table, and
+it was not long before they attracted Bernardo's attention.
+
+"I see you are a collector yourself," he ventured, picking them
+up.
+
+"Yes," answered Craig, offhand; "I picked them up yesterday at
+Sato's. You know the place?"
+
+"Oh, yes, I know Sato," answered the curator, seemingly without
+the slightest hesitation. "He has been in Mexico--is quite a
+student."
+
+"And the other man, Otaka?"
+
+"Other man--Otaka? You mean his wife?"
+
+I saw Kennedy check a motion of surprise and came to the rescue
+with the natural question: "His wife--with a beard and mustache?"
+
+It was Bernardo's turn to be surprised. He looked at me a moment,
+then saw that I meant it, and suddenly his face lighted up.
+
+"Oh," he exclaimed, "that must have been on account of the
+immigration laws or something of the sort. Otaka is his wife. The
+Ainus are much sought after by the Japanese as wives. The women,
+you know, have a custom of tattooing mustaches on themselves. It
+is hideous, but they think it is beautiful."
+
+"I know," I pursued, watching Kennedy's interest in our
+conversation, "but this was not tattooed."
+
+"Well, then, it must have been false," insisted Bernardo.
+
+The curator chatted a few moments, during which I expected Kennedy
+to lead the conversation around to Senora Herreria. But he did
+not, evidently fearing to show his hand.
+
+"What did you make of it?" I asked, when he had gone. "Is he
+trying to hide something?"
+
+"I think he has simplified the case," remarked Craig, leaning
+back, his hands behind his head, gazing up at the ceiling. "Hello,
+here's Leslie! What did you find, Doctor?" The coroner had entered
+with a look of awe on his face, as if Kennedy had directed him by
+some sort of necromancy.
+
+"It was Senora Herreria!" he exclaimed. "She has been missing from
+the hotel ever since late yesterday afternoon. What do you think
+of it?"
+
+"I think," replied Kennedy, speaking slowly and deliberately,
+"that it is very much like the Northrop case. You haven't taken
+that up yet?"
+
+"Only superficially. What do you make of it?" asked the coroner.
+
+"I had an idea that it might be aconitin poisoning," he said.
+
+Leslie glanced at him keenly for a moment. "Then you'll never
+prove anything in the laboratory," he said.
+
+"There are more ways of catching a criminal, Leslie," put in
+Craig, "than are set down in the medico-legal text-books. I shall
+depend on you and Jameson to gather together a rather cosmopolitan
+crowd here to-night."
+
+He said it with a quiet confidence which I could not gainsay,
+although I did not understand. However, mostly with the official
+aid of Doctor Leslie, I followed out his instructions, and it was
+indeed a strange party that assembled that night. There were
+Doctor Bernardo; Sato, the curio dealer; Otaka, the Ainu, and
+ourselves. Mrs. Northrop, of course, could not come.
+
+"Mexico," began Craig, after he had said a few words explaining
+why he had brought us together, "is full of historical treasure.
+To all intents and purposes, the government says, 'Come and dig.'
+But when there are finds, then the government swoops down on them
+for its own national museum. The finder scarcely gets a chance to
+export them. However, now seemed to be the time to Professor
+Northrop to smuggle his finds out of the country.
+
+"But evidently it could not be done without exciting all kinds of
+rumors and suspicions. Stories seem to have spread far and fast
+about what he had discovered. He realized the unsettled condition
+of the country--perhaps wanted to confirm his reading of a certain
+inscription by consultation with one scholar whom he thought he
+could trust. At any rate, he came home."
+
+Kennedy paused, making use of the silence for emphasis. "You have
+all read of the wealth that Cortez found in Mexico. Where are the
+gold and silver of the conquistadores? Gone to the melting pot,
+centuries ago. But is there none left? The Indians believe so.
+There are persons who would stop at nothing--even at murder of
+American professors, murder of their own comrades, to get at the
+secret."
+
+He laid his hand almost lovingly on his powerful little microscope
+as he resumed on another line of evidence.
+
+"And while we are on the subject of murders, two very similar
+deaths have occurred," he went on. "It is of no use to try to
+gloss them over. Frankly, I suspected that they might have been
+caused by aconite poisoning. But, in the case of such poisoning,
+not only is the lethal dose very small but our chemical methods of
+detection are nil. The dose of the active principle, aconitin
+nitrate, is about one six-hundredth of a grain. There are no color
+tests, no reactions, as in the case of the other organic poisons."
+
+I wondered what he was driving at. Was there, indeed, no test? Had
+the murderer used the safest of poisons--one that left no clue? I
+looked covertly at Sato's face. It was impassive. Doctor Bernardo
+was visibly uneasy as Kennedy proceeded. Cool enough up to the
+time of the mention of the treasure, I fancied, now, that he was
+growing more and more nervous.
+
+Craig laid down on the table the reed stick with the little
+darkened cylinder on the end.
+
+"That," he said, "is a little article which I picked up beneath
+Northrop's window yesterday. It is a piece of anno-noki, or
+bushi." I fancied I saw just a glint of satisfaction in Otaka's
+eyes.
+
+"Like many barbarians," continued Craig, "the Ainus from time
+immemorial have prepared virulent poisons with which they charged
+their weapons of the chase and warfare. The formulas for the
+preparations, as in the case of other arrow poisons of other
+tribes, are known only to certain members, and the secret is
+passed down from generation to generation as an heirloom, as it
+were. But in this case it is no longer a secret. It has now been
+proved that the active principle of this poison is aconite."
+
+"If that is the case," broke in Doctor Leslie, "it is hopeless to
+connect anyone directly in that way with these murders. There is
+no test for aconitin."
+
+I thought Sato's face was more composed and impassive than ever.
+Doctor Bernardo, however, was plainly excited.
+
+"What--no test--NONE?" asked Kennedy, leaning forward eagerly.
+Then, as if he could restrain the answer to his own question no
+longer, he shot out: "How about the new starch test just
+discovered by Professor Reichert, of the University of
+Pennsylvania? Doubtless you never dreamed that starch may be a
+means of detecting the nature of a poison in obscure cases in
+criminology, especially in cases where the quantity of poison
+necessary to cause death is so minute that no trace of it can be
+found in the blood.
+
+"The starch method is a new and extremely inviting subject to me.
+The peculiarities of the starch of any plant are quite as
+distinctive of the plant as are those of the hemoglobin crystals
+in the blood of an animal. I have analyzed the evidence of my
+microscope in this case thoroughly. When the arrow poison is
+introduced subcutaneously--say, by a person shooting a poisoned
+dart, which he afterward removes in order to destroy the evidence-
+-the lethal constituents are rapidly absorbed.
+
+"But the starch remains in the wound. It can be recovered and
+studied microscopically and can be definitely recognized. Doctor
+Reichert has published a study of twelve hundred such starches
+from all sorts of plants. In this case, it not only proves to be
+aconitin but the starch granules themselves can be recognized.
+They came from this piece of arrow poison."
+
+Every eye was fixed on him now.
+
+"Besides," he rapped out, "in the soft soil beneath the window of
+Professor Northrop's room, I found footprints. I have only to
+compare the impressions I took there and those of the people in
+this room, to prove that, while the real murderer stood guard
+below the window, he sent some one more nimble up the rain pipe to
+shoot the poisoned dart at Professor Northrop, and, later, to let
+down a rope by which he, the instigator, could gain the room,
+remove the dart, and obtain the key to the treasure he sought."
+
+Kennedy was looking straight at Professor Bernardo.
+
+"A friend of mine in Mexico has written me about an inscription,"
+he burst out. "I received the letter only to-day. As nearly as I
+can gather, there was an impression that some of Northrop's stuff
+would be valuable in proving the alleged kinship between Mexico
+and Japan, perhaps to arouse hatred of the United States."
+
+"Yes--that is all very well," insisted Kennedy. "But how about the
+treasure?"
+
+"Treasure?" repeated Bernardo, looking from one of us to another.
+
+"Yes," pursued Craig relentlessly, "the treasure. You are an
+expert in reading the hieroglyphics. By your own statement, you
+and Northrop had been going over the stuff he had sent up. You
+know it."
+
+Bernardo gave a quick glance from Kennedy to me. Evidently he saw
+that the secret was out.
+
+"Yes," he said huskily, in a low tone, "Northrop and I were to
+follow the directions after we had plotted them out and were to
+share it together on the next expedition, which I could direct as
+a Mexican without so much suspicion. I should still have shared it
+with his widow if this unfortunate affair had not exposed the
+secret."
+
+Bernardo had risen earnestly.
+
+"Kennedy," he cried, "before God, if you will get back that stone
+and keep the secret from going further than this room, I will
+prove what I have said by dividing the Mixtec treasure with Mrs.
+Northrop and making her one of the richest widows in the country!"
+
+"That is what I wanted to be sure of," nodded Craig. "Bernardo,
+Senora Herreria, of whom your friend wrote to you from Mexico, has
+been murdered in the same way that Professor Northrop was. Otaka
+was sent by her husband to murder Northrop, in order that they
+might obtain the so-called 'Pillar of Death' and the key to the
+treasure. Then, when the senora was no doubt under the influence
+of sake in the pretty little Oriental bower at the curio shop, a
+quick jab, and Otaka had removed one who shared the secret with
+them."
+
+He had turned and faced the pair.
+
+"Sato," he added, "you played on the patriotism of the senora
+until you wormed from her the treasure secret. Evidently rumors of
+it had spread from Mexican Indians to Japanese visitors. And then,
+Otaka, all jealousy over one whom she, no doubt, justly considered
+a rival, completed your work by sending her forth to die, unknown,
+on the street. Walter, ring up First Deputy O'Connor. The stone is
+hidden somewhere in the curio shop. We can find it without Sato's
+help. The quicker such a criminal is lodged safely in jail, the
+better for humanity."
+
+Sato was on his feet, advancing cautiously toward Craig. I knew
+the dangers, now, of anno-noki, as well as the wonders of jujutsu,
+and, with a leap, I bounded past Bernardo and between Sato and
+Kennedy.
+
+How it happened, I don't know, but, an instant later, I was
+sprawling.
+
+Before I could recover myself, before even Craig had a chance to
+pull the hair-trigger of his automatic, Sato had seized the Ainu
+arrow poison from the table, had bitten the little cylinder in
+half, and had crammed the other half into the mouth of Otaka.
+
+
+
+
+CHAPTER XIII
+
+THE RADIUM ROBBER
+
+
+Kennedy simply reached for the telephone and called an ambulance.
+But it was purely perfunctory. Dr. Leslie himself was the only
+official who could handle Sato's case now.
+
+We had planned a little vacation for ourselves, but the planning
+came to naught. The next night we spent on a sleeper. That in
+itself is work to me.
+
+It all came about through a hurried message from Murray Denison,
+president of the Federal Radium Corporation. Nothing would do but
+that he should take both Kennedy and myself with him post-haste to
+Pittsburgh at the first news of what had immediately been called
+"the great radium robbery."
+
+Of course the newspapers were full of it. The very novelty of an
+ultra-modern cracksman going off with something worth upward of a
+couple of hundred thousand dollars--and all contained in a few
+platinum tubes which could be tucked away in a vest pocket--had
+something about it powerfully appealing to the imagination.
+
+"Most ingenious, but, you see, the trouble with that safe is that
+it was built to keep radium IN--not cracksmen OUT," remarked
+Kennedy, when Denison had rushed us from the train to take a look
+at the little safe in the works of the Corporation.
+
+"Breaking into such a safe as this," added Kennedy, after a
+cursory examination, "is simple enough, after all."
+
+It was, however, a remarkably ingenious contrivance, about three
+feet in height and of a weight of perhaps a ton and a half, and
+all to house something weighing only a few grains.
+
+"But," Denison hastened to explain, "we had to protect the radium
+not only against burglars, but, so to speak, against itself.
+Radium emanations pass through steel and experiments have shown
+that the best metal to contain them is lead. So, the difficulty
+was solved by making a steel outer case enclosing an inside leaden
+shell three inches thick."
+
+Kennedy had been toying thoughtfully with the door.
+
+"Then the door, too, had to be contrived so as to prevent any
+escape of the emanations through joints. It is lathe turned and
+circular, a 'dead fit.' By means of a special contrivance any
+slight looseness caused by wear and tear of closing can be
+adjusted. And another feature. That is the appliance for
+preventing the loss of emanation when the door is opened. Two
+valves have been inserted into the door and before it is opened
+tubes with mercury are passed through which collect and store the
+emanation."
+
+"All very nice for the radium," remarked Craig cheerfully. "But
+the fellow had only to use an electric drill and the gram or more
+of radium was his."
+
+"I know that--now," ruefully persisted Denison. "But the safe was
+designed for us specially. The fellow got into it and got away, as
+far as I can see, without leaving a clue."
+
+"Except one, of course," interrupted Kennedy quickly.
+
+Denison looked at him a moment keenly, then nodded and said, "Yes-
+-you are right. You mean one which he must bear on himself?"
+
+"Exactly. You can't carry a gram or more of radium bromide long
+with impunity. The man to look for is one who in a few days will
+have somewhere on his body a radium burn which will take months to
+heal. The very thing he stole is a veritable Frankenstein's
+monster bent on the destruction of the thief himself!"
+
+Kennedy had meanwhile picked up one of the Corporation's circulars
+lying on a desk. He ran his eye down the list of names.
+
+"So, Hartley Haughton, the broker, is one of your stockholders,"
+mused Kennedy.
+
+"Not only one but THE one," replied Denison with obvious pride.
+
+Haughton was a young man who had come recently into his fortune,
+and, while no one believed it to be large, he had cut quite a
+figure in Wall Street.
+
+"You know, I suppose," added Denison, "that he is engaged to
+Felicie Woods, the daughter of Mrs. Courtney Woods?"
+
+Kennedy did not, but said nothing.
+
+"A most delightful little girl," continued Denison thoughtfully.
+"I have known Mrs. Woods for some time. She wanted to invest, but
+I told her frankly that this is, after all, a speculation. We may
+not be able to swing so big a proposition, but, if not, no one can
+say we have taken a dollar of money from widows and orphans."
+
+"I should like to see the works," nodded Kennedy approvingly.
+
+"By all means."
+
+The plant was a row of long low buildings of brick on the
+outskirts of the city, once devoted to the making of vanadium
+steel. The ore, as Denison explained, was brought to Pittsburgh
+because he had found here already a factory which could readily be
+turned into a plant for the extraction of radium. Huge baths and
+vats and crucibles for the various acids and alkalis and other
+processes used in treating the ore stood at various points.
+
+"This must be like extracting gold from sea water," remarked
+Kennedy jocosely, impressed by the size of the plant as compared
+to the product.
+
+"Except that after we get through we have something infinitely
+more precious than gold," replied Denison, "something which
+warrants the trouble and outlay. Yes, the fact is that the
+percentage of radium in all such ores is even less than of gold in
+sea water."
+
+"Everything seems to be most carefully guarded," remarked Kennedy
+as we concluded our tour of the well-appointed works.
+
+He had gone over everything in silence, and now at last we had
+returned to the safe.
+
+"Yes," he repeated slowly, as if confirming his original
+impression, "such an amount of radium as was stolen wouldn't
+occasion immediate discomfort to the thief, I suppose, but later
+no infernal machine could be more dangerous to him."
+
+I pictured to myself the series of fearful works of mischief and
+terror that might follow, a curse on the thief worse than that of
+the weirdest curses of the Orient, the danger to the innocent, and
+the fact that in the hands of a criminal it was an instrument for
+committing crimes that might defy detection.
+
+"There is nothing more to do here now," he concluded. "I can see
+nothing for the present except to go back to New York. The
+telltale burn may not be the only clue, but if the thief is going
+to profit by his spoils we shall hear about it best in New York or
+by cable from London, Paris, or some other European city."
+
+Our hurried departure from New York had not given us a chance to
+visit the offices of the Radium Corporation for the distribution
+of the salts themselves. They were in a little old office building
+on William Street, near the drug district and yet scarcely a
+moment's walk from the financial district.
+
+"Our head bookkeeper, Miss Wallace, is ill," remarked Denison when
+we arrived at the office, "but if there is anything I can do to
+help you, I shall be glad to do it. We depend on Miss Wallace a
+great deal. Haughton says she is the brains of the office."
+
+Kennedy looked about the well-appointed suite curiously.
+
+"Is this another of those radium safes?" he asked, approaching one
+similar in appearance to that which had been broken open already.
+
+"Yes, only a little larger."
+
+"How much is in it?"
+
+"Most of our supply. I should say about two and a half grams. Miss
+Wallace has the record."
+
+"It is of the same construction, I presume," pursued Kennedy. "I
+wonder whether the lead lining fits closely to the steel?"
+
+"I think not," considered Denison. "As I remember there was a sort
+of insulating air cushion or something of the sort."
+
+Denison was quite eager to show us about. In fact ever since he
+had hustled us out to view the scene of the robbery, his high
+nervous tension had given us scarcely a moment's rest. For hours
+he had talked radium, until I felt that he, like his metal, must
+have an inexhaustible emanation of words. He was one of those
+nervous, active little men, a born salesman, whether of ribbons or
+radium.
+
+"We have just gone into furnishing radium water," he went on,
+bustling about and patting a little glass tank.
+
+I looked closely and could see that the water glowed in the dark
+with a peculiar phosphorescence.
+
+"The apparatus for the treatment," he continued, "consists of two
+glass and porcelain receptacles. Inside the larger receptacle is
+placed the smaller, which contains a tiny quantity of radium. Into
+the larger receptacle is poured about a gallon of filtered water.
+The emanation from that little speck of radium is powerful enough
+to penetrate its porcelain holder and charge the water with its
+curative properties. From a tap at the bottom of the tank the
+patient draws the number of glasses of water a day prescribed. For
+such purposes the emanation within a day or two of being collected
+is as good as radium itself. Why, this water is five thousand
+times as radioactive as the most radioactive natural spring
+water."
+
+"You must have control of a comparatively large amount of the
+metal," suggested Kennedy.
+
+"We are, I believe, the largest holders of radium in the world,"
+he answered. "I have estimated that all told there are not much
+more than ten grams, of which Madame Curie has perhaps three,
+while Sir Ernest Cassel of London is the holder of perhaps as
+much. We have nearly four grams, leaving about six or seven for
+the rest of the world."
+
+Kennedy nodded and continued to look about.
+
+"The Radium Corporation," went on Denison, "has several large
+deposits of radioactive ore in Utah in what is known as the Poor
+Little Rich Valley, a valley so named because from being about the
+barrenest and most unproductive mineral or agricultural hole in
+the hills, the sudden discovery of the radioactive deposits has
+made it almost priceless."
+
+He had entered a private office and was looking over some mail
+that had been left on his desk during his absence.
+
+"Look at this," he called, picking up a clipping from a newspaper
+which had been laid there for his attention. "You see, we have
+them aroused."
+
+We read the clipping together hastily:
+
+PLAN TO CORNER WORLD'S RADIUM
+
+LONDON.--Plans are being matured to form a large corporation for
+the monopoly of the existing and future supply of radium
+throughout the world. The company is to be called Universal
+Radium, Limited, and the capital of ten million dollars will be
+offered for public subscription at par simultaneously in London,
+Paris and New York.
+
+The company's business will be to acquire mines and deposits of
+radioactive substances as well as the control of patents and
+processes connected with the production of radium. The outspoken
+purpose of the new company is to obtain a world-wide monopoly and
+maintain the price.
+
+ "Ah--a competitor," commented Kennedy, handing back the clipping.
+
+"Yes. You know radium salts used always to come from Europe. Now
+we are getting ready to do some exporting ourselves. Say," he
+added excitedly, "there's an idea, possibly, in that."
+
+"How?" queried Craig.
+
+"Why, since we should be the principal competitors to the foreign
+mines, couldn't this robbery have been due to the machinations of
+these schemers? To my mind, the United States, because of its
+supply of radium-bearing ores, will have to be reckoned with first
+in cornering the market. This is the point, Kennedy. Would those
+people who seem to be trying to extend their new company all over
+the world stop at anything in order to cripple us at the start?"
+
+How much longer Denison would have rattled on in his effort to
+explain the robbery, I do not know. The telephone rang and a
+reporter from the Record, who had just read my own story in the
+Star, asked for an interview. I knew that it would be only a
+question of minutes now before the other men were wearing a path
+out on the stairs, and we managed to get away before the onrush
+began.
+
+"Walter," said Kennedy, as soon as we had reached the street. "I
+want to get in touch with Halsey Haughton. How can it be done?"
+
+I could think of nothing better at that moment than to inquire at
+the Star's Wall Street office, which happened to be around the
+corner. I knew the men down there intimately, and a few minutes
+later we were whisked up in the elevator to the office.
+
+They were as glad to see me as I was to see them, for the story of
+the robbery had interested the financial district perhaps more
+than any other.
+
+"Where can I find Halsey Haughton at this hour?" I asked.
+
+"Say," exclaimed one of the men, "what's the matter? There have
+been all kinds of rumors in the Street about him to-day. Did you
+know he was ill?"
+
+"No," I answered. "Where is he?"
+
+"Out at the home of his fiancee, who is the daughter of Mrs.
+Courtney Woods, at Glenclair."
+
+"What's the matter?" I persisted.
+
+"That's just it. No one seems to know. They say--well--they say he
+has a cancer."
+
+Halsey Haughton suffering from cancer? It was such an uncommon
+thing to hear of a young man that I looked up quickly in surprise.
+Then all at once it flashed over me that Denison and Kennedy had
+discussed the matter of burns from the stolen radium. Might not
+this be, instead of cancer, a radium burn?
+
+Kennedy, who had been standing a little apart from me while I was
+talking with the boys, signaled to me with a quick glance not to
+say too much, and a few minutes later we were on the street again.
+
+I knew without being told that he was bound by the next train to
+the pretty little New Jersey suburb of Glenclair.
+
+It was late when we arrived, yet Kennedy had no hesitation in
+calling at the quaint home of Mrs. Courtney Woods on Woodridge
+Avenue.
+
+Mrs. Woods, a well-set-up woman of middle age, who had retained
+her youth and good looks in a remarkable manner, met us in the
+foyer. Briefly, Kennedy explained that we had just come in from
+Pittsburgh with Mr. Denison and that it was very important that we
+should see Haughton at once.
+
+We had hardly told her the object of our visit when a young woman
+of perhaps twenty-two or three, a very pretty girl, with all the
+good looks of her mother and a freshness which only youth can
+possess, tiptoed quietly downstairs. Her face told plainly that
+she was deeply worried over the illness of her fiance.
+
+"Who is it, mother?" she whispered from the turn in the stairs.
+"Some gentlemen from the company? Hartley's door was open when the
+bell rang, and he thought he heard something said about the
+Pittsburgh affair."
+
+Though she had whispered, it had not been for the purpose of
+concealing anything from us, but rather that the keen ears of her
+patient might not catch the words. She cast an inquiring glance at
+us.
+
+"Yes," responded Kennedy in answer to her look, modulating his
+tone. "We have just left Mr. Denison at the office. Might we see
+Mr. Haughton for a moment? I am sure that nothing we can say or do
+will be as bad for him as our going away, now that he knows that
+we are here."
+
+The two women appeared to consult for a moment.
+
+"Felicie," called a rather nervous voice from the second floor,
+"is it some one from the company?"
+
+"Just a moment, Hartley," she answered, then, lower to her mother,
+added, "I don't think it can do any harm, do you, mother?"
+
+"You remember the doctor's orders, my dear."
+
+Again the voice called her.
+
+"Hang the doctor's orders," the girl exclaimed, with an air of
+almost masculinity. "It can't be half so bad as to have him worry.
+Will you promise not to stay long? We expect Dr. Bryant in a few
+moments, anyway."
+
+
+
+
+CHAPTER XIV
+
+THE SPINTHARISCOPE
+
+
+We followed her upstairs and into Haughton's room, where he was
+lying in bed, propped up by pillows. Haughton certainly was ill.
+There was no mistake about that. He was a tall, gaunt man with an
+air about him that showed that he found illness very irksome.
+Around his neck was a bandage, and some adhesive tape at the back
+showed that a plaster of some sort had been placed there.
+
+As we entered his eyes traveled restlessly from the face of the
+girl to our own in an inquiring manner. He stretched out a nervous
+hand to us, while Kennedy in a few short sentences explained how
+we had become associated with the case and what we had seen
+already.
+
+"And there is not a clue?" he repeated as Craig finished.
+
+"Nothing tangible yet," reiterated Kennedy. "I suppose you have
+heard of this rumor from London of a trust that is going into the
+radium field internationally?"
+
+"Yes," he answered, "that is the thing you read to me in the
+morning papers, you remember, Felicie. Denison and I have heard
+such rumors before. If it is a fight, then we shall give them a
+fight. They can't hold us up, if Denison is right in thinking that
+they are at the bottom of this--this robbery."
+
+"Then you think he may be right?" shot out Kennedy quickly.
+
+Haughton glanced nervously from Kennedy to me.
+
+"Really," he answered, "you see how impossible it is for me to
+have an opinion? You and Denison have been over the ground. You
+know much more about it than I do. I am afraid I shall have to
+defer to you."
+
+Again we heard the bell downstairs, and a moment later a cheery
+voice, as Mrs. Woods met some one down in the foyer, asked, "How
+is the patient to-night?"
+
+We could not catch the reply.
+
+"Dr. Bryant, my physician," put in Haughton. "Don't go. I will
+assume the responsibility for your being here. Hello, Doctor. Why,
+I'm much the same to-night, thank you. At least no worse since I
+took your advice and went to bed."
+
+Dr. Bryant was a bluff, hearty man, with the personal magnetism
+which goes with the making of a successful physician. He had
+mounted the stairs quietly but rapidly, evidently prepared to see
+us.
+
+"Would you mind waiting in this little dressing room?" asked the
+doctor, motioning to another, smaller room adjoining.
+
+He had taken from his pocket a little instrument with a dial face
+like a watch, which he attached to Haughton's wrist. "A pocket
+instrument to measure blood pressure," whispered Craig, as we
+entered the little room.
+
+While the others were gathered about Haughton, we stood in the
+next room, out of earshot. Kennedy had leaned his elbow on a
+chiffonier. As he looked about the little room, more from force of
+habit than because he thought he might discover anything,
+Kennedy's eye rested on a glass tray on the top in which lay some
+pins, a collar button or two, which Haughton had apparently just
+taken off, and several other little unimportant articles.
+
+Kennedy bent over to look at the glass tray more closely, a
+puzzled look crossed his face, and with a glance at the other room
+he gathered up the tray and its contents.
+
+"Keep up a good courage," said Dr. Bryant. "You'll come out all
+right, Haughton." Then as he left the bedroom he added to us,
+"Gentlemen, I hope you will pardon me, but if you could postpone
+the remainder of your visit until a later day, I am sure you will
+find it more satisfactory."
+
+There was an air of finality about the doctor, though nothing
+unpleasant in it. We followed him down the stairs, and as we did
+so, Felicie, who had been waiting in a reception room, appeared
+before the portieres, her earnest eyes fixed on his kindly face.
+
+"Dr. Bryant," she appealed, "is he--is he, really--so badly?"
+
+The Doctor, who had apparently known her all her life, reached
+down and took one of her hands, patting it with his own in a
+fatherly way. "Don't worry, little girl," he encouraged. "We are
+going to come out all right--all right."
+
+She turned from him to us and, with a bright forced smile which
+showed the stuff she was made of, bade us good night.
+
+Outside, the Doctor, apparently regretting that he had virtually
+forced us out, paused before his car. "Are you going down toward
+the station? Yes? I am going that far. I should be glad to drive
+you there."
+
+Kennedy climbed into the front seat, leaving me in the rear where
+the wind wafted me their brief conversation as we sped down
+Woodbridge Avenue.
+
+"What seems to be the trouble?" asked Craig.
+
+"Very high blood pressure, for one thing," replied the Doctor
+frankly.
+
+"For which the latest thing is the radium water cure, I suppose?"
+ventured Kennedy.
+
+"Well, radioactive water is one cure for hardening of the
+arteries. But I didn't say he had hardening of the arteries.
+Still, he is taking the water, with good results. You are from the
+company?"
+
+Kennedy nodded.
+
+"It was the radium water that first interested him in it. Why, we
+found a pressure of 230 pounds, which is frightful, and we have
+brought it down to 150, not far from normal."
+
+"Still that could have nothing to do with the sore on his neck,"
+hazarded Kennedy.
+
+The Doctor looked at him quickly, then ahead at the path of light
+which his motor shed on the road.
+
+He said nothing, but I fancied that even he felt there was
+something strange in his silence over the new complication. He did
+not give Kennedy a chance to ask whether there were any other such
+sores.
+
+"At any rate," he said, as he throttled down his engine with a
+flourish before the pretty little Glenclair station, "that girl
+needn't worry."
+
+There was evidently no use in trying to extract anything further
+from him. He had said all that medical ethics or detective skill
+could get from him. We thanked him and turned to the ticket window
+to see how long we should have to wait.
+
+"Either that doctor doesn't know what he is talking about or he is
+concealing something," remarked Craig, as we paced up and down the
+platform. "I am inclined to read the enigma in the latter way."
+
+Nothing more passed between us during the journey back, and we
+hurried directly to the laboratory, late as it was. Kennedy had
+evidently been revolving something over and over in his mind, for
+the moment he had switched on the light, he unlocked one of his
+air-and dust-proof cabinets and took from it an instrument which
+he placed on a table before him.
+
+It was a peculiar-looking instrument, like a round glass electric
+battery with a cylinder atop, smaller and sticking up like a
+safety valve. On that were an arm, a dial, and a lens fixed in
+such a way as to read the dial. I could not see what else the
+rather complicated little apparatus consisted of, but inside, when
+Kennedy brought near it the pole of a static electric machine two
+delicate thin leaves of gold seemed to fly wide apart when it was
+charged.
+
+Kennedy had brought the glass tray near the thing. Instantly the
+leaves collapsed and he made a reading through the lens.
+
+"What is it?" I asked.
+
+"A radioscope," he replied, still observing the scale. "Really a
+very sensitive gold leaf electroscope, devised by one of the
+students of Madame Curie. This method of detection is far more
+sensitive even than the spectroscope."
+
+"What does it mean when the leaves collapse?" I asked.
+
+"Radium has been near that tray," he answered. "It is radioactive.
+I suspected it first when I saw that violet color. That is what
+radium does to that kind of glass. You see, if radium exists in a
+gram of inactive matter only to the extent of one in ten-thousand
+million parts its presence can be readily detected by this
+radioscope, and everything that has been rendered radioactive is
+the same. Ordinarily the air between the gold leaves is
+insulating. Bringing something radioactive near them renders the
+air a good conductor and the leaves fall under the radiation."
+
+"Wonderful!" I exclaimed, marveling at the delicacy of it.
+
+"Take radium water," he went on, "sufficiently impregnated with
+radium emanations to be luminous in the dark, like that water of
+Denison's. It would do the same. In fact all mineral waters and
+the so-called curarive muds like fango are slightly radioactive.
+There seems to be a little radium everywhere on earth that
+experiments have been made, even in the interiors of buildings. It
+is ubiquitous. We are surrounded and permeated by radiations--that
+soil out there on the campus, the air of this room, all. But," he
+added contemplatively, "there is something different about that
+tray. A lot of radium has been near that, and recently."
+
+"How about that bandage about Haughton's neck?" I asked suddenly.
+"Do you think radium could have had anything to do with that?"
+"Well, as to burns, there is no particular immediate effect
+usually, and sometimes even up to two weeks or more, unless the
+exposure has been long and to a considerable quantity. Of course
+radium keeps itself three or four degrees warmer than other things
+about it constantly. But that isn't what does the harm. It is
+continually emitting little corpuscles, which I'll explain some
+other time, traveling all the way from twenty to one hundred and
+thirty thousand miles a second, and these corpuscles blister and
+corrode the flesh like quick-moving missiles bombarding it. The
+gravity of such lesions increases with the purity of the radium.
+For instance I have known an exposure of half an hour to a
+comparatively small quantity through a tube, a box and the clothes
+to produce a blister fifteen days later. Curie said he wouldn't
+trust himself in a room with a kilogram of it. It would destroy
+his eyesight, burn off his skin and kill him eventually. Why, even
+after a slight exposure your clothes are radioactive--the
+electroscope will show that."
+
+He was still fumbling with the glass plate and the various
+articles on it.
+
+"There's something very peculiar about all this," he muttered,
+almost to himself.
+
+Tired by the quick succession of events of the past two days, I
+left Kennedy still experimenting in his laboratory and retired,
+still wondering when the real clue was to develop. Who could it
+have been who bore the tell-tale burn? Was the mark hidden by the
+bandage about Haughton's neck the brand of the stolen tubes? Or
+were there other marks on his body which we could not see?
+
+No answer came to me, and I fell asleep and woke up without a
+radiation of light on the subject. Kennedy spent the greater part
+of the day still at work at his laboratory, performing some very
+delicate experiments. Finding nothing to do there, I went down to
+the Star office and spent my time reading the reports that came in
+from the small army of reporters who had been assigned to run down
+clues in the case which was the sensation of the moment. I have
+always felt my own lips sealed in such cases, until the time came
+that the story was complete and Kennedy released me from any
+further need of silence. The weird and impossible stories which
+came in not only to the Star but to the other papers surely did
+make passable copy in this instance, but with my knowledge of the
+case I could see that not one of them brought us a step nearer the
+truth.
+
+One thing which uniformly puzzled the newspapers was the illness
+of Haughton and his enforced idleness at a time which was of so
+much importance to the company which he had promoted and indeed
+very largely financed. Then, of course, there was the romantic
+side of his engagement to Felicie Woods.
+
+Just what connection Felicie Woods had with the radium robbery if
+any, I was myself unable quite to fathom. Still, that made no
+difference to the papers. She was pretty and therefore they
+published her picture, three columns deep, with Haughton and
+Denison, who were intimately concerned with the real loss in
+little ovals perhaps an inch across and two inches in the opposite
+dimension.
+
+The late afternoon news editions had gone to press, and I had
+given up in despair, determined to go up to the laboratory and sit
+around idly watching Kennedy with his mystifying experiments, in
+preference to waiting for him to summon me.
+
+I had scarcely arrived and settled myself to an impatient watch,
+when an automobile drove up furiously, and Denison himself, very
+excited, jumped out and dashed into the laboratory.
+
+"What's the matter?" asked Kennedy, looking up from a test tube
+which he had been examining, with an air for all the world
+expressive of "Why so hot, little man?"
+
+"I've had a threat," ejaculated Denison.
+
+He laid on one of the laboratory tables a letter, without heading
+and without signature, written in a disguised hand, with an
+evident attempt to simulate the cramped script of a foreign
+penmanship.
+
+"I know who did the Pittsburgh job. The same party is out to ruin
+Federal Radium. Remember Pittsburgh and be prepared!
+
+"A STOCKHOLDER."
+
+"Well?" demanded Kennedy, looking up.
+
+"That can have only one meaning," asserted Denison.
+
+"What is that?" inquired Kennedy coolly, as if to confirm his own
+interpretation.
+
+"Why, another robbery--here in New York, of course."
+
+"But who would do it?" I asked.
+
+"Who?" repeated Denison. "Some one representing that European
+combine, of course. That is only part of the Trust method--ruin of
+competitors whom they cannot absorb."
+
+"Then you have refused to go into the combine? You know who is
+backing it?"
+
+"No--no," admitted Denison reluctantly. "We have only signified
+our intent to go it alone, as often as anyone either with or
+without authority has offered to buy us out. No, I do not even
+know who the people are. They never act in the open. The only
+hints I have ever received were through perfectly reputable
+brokers acting for others."
+
+"Does Haughton know of this note?" asked Kennedy.
+
+"Yes. As soon as I received it, I called him up."
+
+"What did he say?"
+
+"He said to disregard it. But--you know what condition he is in. I
+don't know what to do, whether to surround the office by a squad
+of detectives or remove the radium to a regular safety deposit
+vault, even at the loss of the emanation. Haughton has left it to
+me."
+
+Suddenly the thought flashed across my mind that perhaps Haughton
+could act in this uninterested fashion because he had no fear of
+ruin either way. Might he not be playing a game with the
+combination in which he had protected himself so that he would
+win, no matter what happened?
+
+"What shall I do?" asked Denison. "It is getting late."
+
+"Neither," decided Kennedy.
+
+Denison shook his head. "No," he said, "I shall have some one
+watch there, anyhow."
+
+
+
+
+CHAPTER XV
+
+THE ASPHYXIATING SAFE
+
+
+Denison had scarcely gone to arrange for some one to watch the
+office that night, when Kennedy, having gathered up his radioscope
+and packed into a parcel a few other things from various cabinets,
+announced: "Walter, I must see that Miss Wallace, right away.
+Denison has already given me her address. Call a cab while I
+finish clearing up here. I don't like the looks of this thing,
+even if Haughton does neglect it."
+
+We found Miss Wallace at a modest boarding-house in an old but
+still respectable part of the city. She was a very pretty girl, of
+the slender type, rather a business woman than one given much to
+amusement. She had been ill and was still ill. That was evident
+from the solicitous way in which the motherly landlady scrutinized
+two strange callers.
+
+Kennedy presented a card from Denison, and she came down to the
+parlor to see us.
+
+"Miss Wallace," began Kennedy, "I know it is almost cruel to
+trouble you when you are not feeling like office work, but since
+the robbery of the safe at Pittsburgh, there have been threats of
+a robbery of the New York office."
+
+She started involuntarily, and it was evident, I thought, that she
+was in a very high-strung state.
+
+"Oh," she cried, "why, the loss means ruin to Mr. Denison!"
+
+There were genuine tears in her eyes as she said it.
+
+"I thought you would be willing to aid us," pursued Kennedy
+sympathetically. "Now, for one thing, I want to be perfectly sure
+just how much radium the Corporation owns, or rather owned before
+the first robbery."
+
+"The books will show it," she said simply.
+
+"They will?" commented Kennedy. "Then if you will explain to me
+briefly just the system you used in keeping account of it, perhaps
+I need not trouble you any more."
+
+"I'll go down there with you," she answered bravely. "I'm better
+to-day, anyhow, I think."
+
+She had risen, but it was evident that she was not as strong as
+she wanted us to think.
+
+"The least I can do is to make it as easy as possible by going in
+a car," remarked Kennedy, following her into the hall where there
+was a telephone.
+
+The hallway was perfectly dark, yet as she preceded us I could see
+that the diamond pin which held her collar in the back sparkled as
+if a lighted candle had been brought near it. I had noticed in the
+parlor that she wore a handsome tortoiseshell comb set with what I
+thought were other brilliants, but when I looked I saw now that
+there was not the same sparkle to the comb which held her dark
+hair in a soft mass. I noticed these little things at the time,
+not because I thought they had any importance, but merely by
+chance, wondering at the sparkle of the one diamond which had
+caught my eye.
+
+"What do you make of her?" I asked as Kennedy finished
+telephoning.
+
+"A very charming and capable girl," he answered noncommittally.
+
+"Did you notice how that diamond in her neck sparkled?" I asked
+quickly.
+
+He nodded. Evidently it had attracted his attention, too.
+
+"What makes it?" I pursued.
+
+"Well, you know radium rays will make a diamond fluoresce in the
+dark."
+
+"Yes," I objected, "but how about those in the comb?"
+
+"Paste, probably," he answered tersely, as we heard her foot on
+the landing. "The rays won't affect paste."
+
+It was indeed a shame to take advantage of Miss Wallace's loyalty
+to Denison, but she was so game about it that I knew only the
+utmost necessity on Kennedy's part would have prompted him to do
+it. She had a key to the office so that it was not necessary to
+wait for Denison, if indeed we could have found him.
+
+Together she and Kennedy went over the records. It seemed that
+there were in the safe twenty-five platinum tubes of one hundred
+milligrams each, and that there had been twelve of the same amount
+at Pittsburgh. Little as it seemed in weight it represented a
+fabulous fortune.
+
+"You have not the combination?" inquired Kennedy.
+
+"No. Only Mr. Denison has that. What are you going to do to
+protect the safe to-night?" she asked.
+
+"Nothing especially," evaded Kennedy.
+
+"Nothing?" she repeated in amazement.
+
+"I have another plan," he said, watching her intently. "Miss
+Wallace, it was too much to ask you to come down here. You are
+ill."
+
+She was indeed quite pale, as if the excitement had been an
+overexertion.
+
+"No, indeed," she persisted. Then, feeling her own weakness, she
+moved toward the door of Denison's office where there was a
+leather couch. "Let me rest here a moment. I do feel queer. I--"
+
+She would have fallen if he had not sprung forward and caught her
+as she sank to the floor, overcome by the exertion.
+
+Together we carried her in to the couch, and as we did so the comb
+from her hair clattered to the floor.
+
+Craig threw open the window, and bathed her face with water until
+there was a faint flutter of the eyelids.
+
+"Walter," he said, as she began to revive, "I leave her to you.
+Keep her quiet for a few moments. She has unintentionally given me
+just the opportunity I want."
+
+While she was yet hovering between consciousness and
+unconsciousness on the couch, he had unwrapped the package which
+he had brought with him. For a moment he held the comb which she
+had dropped near the radioscope. With a low exclamation of
+surprise he shoved it into his pocket.
+
+Then from the package he drew a heavy piece of apparatus which
+looked as if it might be the motor part of an electric fan, only
+in place of the fan he fitted a long, slim, vicious-looking steel
+bit. A flexible wire attached the thing to the electric light
+circuit and I knew that it was an electric drill. With his coat
+off he tugged at the little radium safe until he had moved it out,
+then dropped on his knees behind it and switched the current on in
+the electric drill.
+
+It was a tedious process to drill through the steel of the outer
+casing of the safe and it was getting late. I shut the door to the
+office so that Miss Wallace could not see.
+
+At last by the cessation of the low hum of the boring, I knew that
+he had struck the inner lead lining. Quietly I opened the door and
+stepped out. He was injecting something from an hermetically
+sealed lead tube into the opening he had made and allowing it to
+run between the two linings of lead and steel. Then using the tube
+itself he sealed the opening he had made and dabbed a little black
+over it.
+
+Quickly he shoved the safe back, then around it concealed several
+small coils with wires also concealed and leading out through a
+window to a court.
+
+"We'll catch the fellow this time," he remarked as he worked. "If
+you ever have any idea, Walter, of going into the burglary
+business, it would be well to ascertain if the safes have any of
+these little selenium cells as suggested by my friend, Mr. Hammer,
+the inventor. For by them an alarm can be given miles away the
+moment an intruder's bull's-eye falls on a hidden cell sensitive
+to light."
+
+While I was delegated to take Miss Wallace home, Kennedy made
+arrangements with a small shopkeeper on the ground floor of a
+building that backed up on the court for the use of his back room
+that night, and had already set up a bell actuated by a system of
+relays which the weak current from the selenium cells could
+operate.
+
+It was not until nearly midnight that he was ready to leave the
+laboratory again, where he had been busily engaged in studying the
+tortoiseshell comb which Miss Wallace in her weakness had
+forgotten.
+
+The little shopkeeper let us in sleepily and Kennedy deposited a
+large round package on a chair in the back of the shop, as well as
+a long piece of rubber tubing. Nothing had happened so far.
+
+As we waited the shopkeeper, now wide awake and not at all
+unconvinced that we were bent on some criminal operation, hung
+around. Kennedy did not seem to care. He drew from his pocket a
+little shiny brass instrument in a lead case, which looked like an
+abbreviated microscope.
+
+"Look through it," he said, handing it to me.
+
+I looked and could see thousands of minute sparks.
+
+"What is it?" I asked.
+
+"A spinthariscope. In that it is possible to watch the bombardment
+of the countless little corpuscles thrown off by radium, as they
+strike on the zinc blende crystal which forms the base. When
+radium was originally discovered, the interest was merely in its
+curious properties, its power to emit invisible rays which
+penetrated solid substances and rendered things fluorescent, of
+expending energy without apparent loss.
+
+"Then came the discovery," he went on, "of its curative powers.
+But the first results were not convincing. Still, now that we know
+the reasons why radium may be dangerous and how to protect
+ourselves against them we know we possess one of the most
+wonderful of curative agencies."
+
+I was thinking rather of the dangers than of the beneficence of
+radium just now, but Kennedy continued.
+
+"It has cured many malignant growths that seemed hopeless, brought
+back destroyed cells, exercised good effects in diseases of the
+liver and intestines and even the baffling diseases of the
+arteries. The reason why harm, at first, as well as good came, is
+now understood. Radium emits, as I told you before, three kinds of
+rays, the alpha, beta, and gamma rays, each with different
+properties. The emanation is another matter. It does not concern
+us in this case, as you will see."
+
+Fascinated as I was by the mystery of the case, I began to see
+that he was gradually arriving at an explanation which had baffled
+everyone else.
+
+"Now, the alpha rays are the shortest," he launched forth, "in
+length let us say one inch. They exert a very destructive effect
+on healthy tissue. That is the cause of injury. They are stopped
+by glass, aluminum and other metals, and are really particles
+charged with positive electricity. The beta rays come next, say,
+about an inch and a half. They stimulate cell growth. Therefore
+they are dangerous in cancer, though good in other ways. They can
+be stopped by lead, and are really particles charged with negative
+electricity. The gamma rays are the longest, perhaps three inches
+long, and it is these rays which effect cures, for they check the
+abnormal and stimulate the normal cells. They penetrate lead. Lead
+seems to filter them out from the other rays. And at three inches
+the other rays don't reach, anyhow. The gamma rays are not charged
+with electricity at all, apparently."
+
+He had brought a little magnet near the spinthariscope. I looked
+into it.
+
+"A magnet," he explained, "shows the difference between the alpha,
+beta, and gamma rays. You see those weak and wobbly rays that seem
+to fall to one side? Those are the alpha rays. They have a strong
+action, though, on tissues and cells. Those falling in the other
+direction are the beta rays. The gamma rays seem to flow
+straight."
+
+"Then it is the alpha rays with which we are concerned mostly
+now?" I queried, looking up.
+
+"Exactly. That is why, when radium is unprotected or
+insufficiently protected and comes too near, it is destructive of
+healthy cells, produces burns, sores, which are most difficult to
+heal. It is with the explanation of such sores that we must deal."
+
+It was growing late. We had waited patiently now for some time.
+Kennedy had evidently reserved this explanation, knowing we should
+have to wait. Still nothing happened.
+
+Added to the mystery of the violet-colored glass plate was now
+that of the luminescent diamond. I was about to ask Kennedy point-
+blank what he thought of them, when suddenly the little bell
+before us began to buzz feebly under the influence of a current.
+
+I gave a start. The faithful little selenium cell burglar alarm
+had done the trick. I knew that selenium was a good conductor of
+electricity in the light, poor in the dark. Some one had,
+therefore, flashed a light on one of the cells in the Corporation
+office. It was the moment for which Kennedy had prepared.
+
+Seizing the round package and the tubing, he dashed out on the
+street and around the corner. He tried the door opening into the
+Radium Corporation hallway. It was closed, but unlocked. As it
+yielded and we stumbled in, up the old worn wooden stairs of the
+building, I knew that there must be some one there.
+
+A terrific, penetrating, almost stunning odor seemed to permeate
+the air even in the hall.
+
+Kennedy paused at the door of the office, tried it, found it
+unlocked, but did not open it.
+
+"That smell is ethyldichloracetate," he explained. "That was what
+I injected into the air cushion of that safe between the two
+linings. I suppose my man here used an electric drill. He might
+have used thermit or an oxyacetylene blowpipe for all I would
+care. These fumes would discourage a cracksman from 'soup' to
+nuts," he laughed, thoroughly pleased at the protection modern
+science had enabled him to devise.
+
+As we stood an instant by the door, I realized what had happened.
+We had captured our man. He was asphyxiated!
+
+Yet how were we to get to him? Would Craig leave him in there,
+perhaps to die? To go in ourselves meant to share his fate,
+whatever might be the effect of the drug.
+
+Kennedy had torn the wrapping off the package. From it he drew a
+huge globe with bulging windows of glass in the front and several
+curious arrangements on it at other points. To it he fitted the
+rubber tubing and a little pump. Then he placed the globe over his
+head, like a diver's helmet, and fastened some air-tight rubber
+arrangement about his neck and shoulders.
+
+"Pump, Walter I" he shouted. "This is an oxygen helmet such as is
+used in entering mines filled with deadly gases."
+
+Without another word he was gone into the blackness of the noxious
+stifle which filled the Radium Corporation office since the
+cracksman had struck the unexpected pocket of rapidly evaporating
+stuff.
+
+I pumped furiously.
+
+Inside I could hear him blundering around. What was he doing?
+
+He was coming back slowly. Was he, too, overcome?
+
+As he emerged into the darkness of the hallway where I myself was
+almost sickened, I saw that he was dragging with him a limp form.
+
+A rush of outside air from the street door seemed to clear things
+a little. Kennedy tore off the oxygen helmet and dropped down on
+his knees beside the figure, working its arms in the most approved
+manner of resuscitation.
+
+"I think we can do it without calling on the pulmotor," he panted.
+"Walter, the fumes have cleared away enough now in the outside
+office. Open a window--and keep that street door open, too."
+
+I did so, found the switch and turned on the lights.
+
+It was Denison himself!
+
+For many minutes Kennedy worked over him. I bent down, loosened
+his collar and shirt, and looked eagerly at his chest for the
+tell-tale marks of the radium which I felt sure must be there.
+There was not even a discoloration.
+
+Not a word was said, as Kennedy brought the stupefied little man
+around.
+
+Denison, pale, shaken, was leaning back now in a big office chair,
+gasping and holding his head.
+
+Kennedy, before him, reached down into his pocket and handed him
+the spinthariscope.
+
+"You see that?" he demanded.
+
+Denison looked through the eyepiece.
+
+"Wh--where did you get so much of it?" he asked, a queer look on
+his face.
+
+"I got that bit of radium from the base of the collar button of
+Hartley Haughton," replied Kennedy quietly, "a collar button which
+some one intimate with him had substituted for his own, bringing
+that deadly radium with only the minutest protection of a thin
+strip of metal close to the back of his neck, near the spinal cord
+and the medulla oblongata which controls blood pressure. That
+collar button was worse than the poisoned rings of the Borgias.
+And there is more radium in the pretty gift of a tortoiseshell
+comb with its paste diamonds which Miss Wallace wore in her hair.
+Only a fraction of an inch, not enough to cut off the deadly alpha
+rays, protected the wearers of those articles."
+
+He paused a moment, while surging through my mind came one after
+another the explanations of the hitherto inexplicable. Denison
+seemed almost to cringe in the chair, weak already from the fumes.
+
+"Besides," went on Kennedy remorselessly, "when I went in there to
+drag you out, I saw the safe open. I looked. There was nothing in
+those pretty platinum tubes, as I suspected. European trust--bah!
+All the cheap devices of a faker with a confederate in London to
+send a cablegram--and another in New York to send a threatening
+letter."
+
+Kennedy extended an accusing forefinger at the man cowering before
+him.
+
+"This is nothing but a get-rich-quick scheme, Denison. There never
+was a milligram of radium in the Poor Little Rich Valley, not a
+milligram here in all the carefully kept reports of Miss Wallace--
+except what was bought outside by the Corporation with the money
+it collected from its dupes. Haughton has been fleeced. Miss
+Wallace, blinded by her loyalty to you--you will always find such
+a faithful girl in such schemes as yours--has been fooled.
+
+"And how did you repay it? What was cleverer, you said to
+yourself, than to seem to be robbed of what you never had, to
+blame it on a bitter rival who never existed? Then to make
+assurance doubly sure, you planned to disable, perhaps get rid of
+the come-on whom you had trimmed, and the faithful girl whose eyes
+you had blinded to your gigantic swindle.
+
+"Denison," concluded Kennedy, as the man drew back, his very face
+convicting him, "Denison, you are the radium robber--robber in
+another sense!"
+
+
+
+
+CHAPTER XVI
+
+THE DEAD LINE
+
+
+Maiden Lane, no less than Wall Street, was deeply interested in
+the radium case. In fact, it seemed that one case in this section
+of the city led to another.
+
+Naturally, the Star and the other papers made much of the capture
+of Denison. Still, I was not prepared for the host of Maiden Lane
+cases that followed. Many of them were essentially trivial. But
+one proved to be of extreme importance.
+
+"Professor Kennedy, I have just heard of your radium case, and I--
+I feel that I can--trust you."
+
+There was a note of appeal in the hesitating voice of the tall,
+heavily veiled woman whose card had been sent up to us with a
+nervous "Urgent" written across its face.
+
+It was very early in the morning, but our visitor was evidently
+completely unnerved by some news which she had just received and
+which had sent her posting to see Craig.
+
+Kennedy met her gaze directly with a look that arrested her
+involuntary effort to avoid it again. She must have read in his
+eyes more than in his words that she might trust him.
+
+"I--I have a confession to make," she faltered.
+
+"Please sit down, Mrs. Moulton," he said simply. "It is my
+business to receive confidences--and to keep them."
+
+She sank into, rather than sat down in, the deep leather rocker
+beside his desk, and now for the first time raised her veil.
+
+Antoinette Moulton was indeed stunning, an exquisite creature with
+a wonderful charm of slender youth, brightness of eye and brunette
+radiance.
+
+I knew that she had been on the musical comedy stage and had had a
+rapid rise to a star part before her marriage to Lynn Moulton, the
+wealthy lawyer, almost twice her age. I knew also that she had
+given up the stage, apparently without a regret. Yet there was
+something strange about the air of secrecy of her visit. Was there
+a hint in it of a disagreement between the Moultons, I wondered,
+as I waited while Kennedy reassured her.
+
+Her distress was so unconcealed that Craig, for the moment, laid
+aside his ordinary inquisitorial manner. "Tell me just as much or
+just as little as you choose, Mrs. Moulton," he added tactfully.
+"I will do my best."
+
+A look almost of gratitude crossed her face.
+
+"When we were married," she began again, "my husband gave me a
+beautiful diamond necklace. Oh, it must have been worth a hundred
+thousand dollars easily. It was splendid. Everyone has heard of
+it. You know, Lynn--er--Mr. Moulton, has always been an
+enthusiastic collector of jewels."
+
+She paused again and Kennedy nodded reassuringly. I knew the
+thought in his mind. Moulton had collected one gem that was
+incomparable with all the hundred thousand dollar necklaces in
+existence.
+
+"Several months ago." she went on rapidly, still avoiding his eyes
+and forcing the words from her reluctant lips, "I--oh, I needed
+money--terribly."
+
+She had risen and faced him, pressing her daintily gloved hands
+together in a little tremble of emotion which was none the less
+genuine because she had studied the art of emotion.
+
+"I took the necklace to a jeweler, Herman Schloss, of Maiden Lane,
+a man with whom my husband had often had dealings and whom I
+thought I could trust. Under a promise of secrecy he loaned me
+fifty thousand dollars on it and had an exact replica in paste
+made by one of his best workmen. This morning, just now, Mr.
+Schloss telephoned me that his safe had been robbed last night. My
+necklace is gone!"
+
+She threw out her hands in a wildly appealing gesture.
+
+"And if Lynn finds that the necklace in our wall safe is of paste-
+-as he will find, for he is an expert in diamonds--oh--what shall
+I do? Can't you--can't you find my necklace?"
+
+Kennedy was following her now eagerly. "You were blackmailed out
+of the money?" he queried casually, masking his question.
+
+There was a sudden, impulsive drooping of her mouth, an evasion
+and keen wariness in her eyes. "I can't see that that has anything
+to do with the robbery," she answered in a low voice.
+
+"I beg your pardon," corrected Kennedy quickly. "Perhaps not. I'm
+sorry. Force of habit, I suppose. You don't know anything more
+about the robbery?"
+
+"N--no, only that it seems impossible that it could have happened
+in a place that has the wonderful burglar alarm protection that
+Mr. Schloss described to me."
+
+"You know him pretty well?"
+
+"Only through this transaction," she replied hastily. "I wish to
+heaven I had never heard of him."
+
+The telephone rang insistently.
+
+"Mrs. Moulton," said Kennedy, as he returned the receiver to the
+hook, "it may interest you to know that the burglar alarm company
+has just called me up about the same case. If I had need of an
+added incentive, which I hope you will believe I have not, that
+might furnish it. I will do my best," he repeated.
+
+"Thank you--a thousand times," she cried fervently, and, had I
+been Craig, I think I should have needed no more thanks than the
+look she gave him as he accompanied her to the door of our
+apartment.
+
+It was still early and the eager crowds were pushing their way to
+business through the narrow network of downtown streets as Kennedy
+and I entered a large office on lower Broadway in the heart of the
+jewelry trade and financial district.
+
+"One of the most amazing robberies that has ever been attempted
+has been reported to us this morning," announced James McLear,
+manager of the Hale Electric Protection, adding with a look half
+of anxiety, half of skepticism, "that is, if it is true."
+
+McLear was a stocky man, of powerful build and voice and a general
+appearance of having been once well connected with the city
+detective force before an attractive offer had taken him into this
+position of great responsibility.
+
+"Herman Schloss, one of the best known of Maiden Lane jewelers,"
+he continued, "has been robbed of goods worth two or three hundred
+thousand dollars--and in spite of every modern protection. So that
+you will get it clearly, let me show you what we do here."
+
+He ushered us into a large room, on the walls of which were
+hundreds of little indicators. From the front they looked like
+rows of little square compartments, tier on tier, about the size
+of ordinary post office boxes. Closer examination showed that each
+was equipped with a delicate needle arranged to oscillate backward
+and forward upon the very minutest interference with the electric
+current. Under the boxes, each of which bore a number, was a
+series of drops and buzzers numbered to correspond with the boxes.
+
+"In nearly every office in Maiden Lane where gems and valuable
+jewelry are stored," explained McLear, "this electrical system of
+ours is installed. When the safes are closed at night and the
+doors swung together, a current of electricity is constantly
+shooting around the safes, conducted by cleverly concealed wires.
+These wires are picked up by a cable system which finds its way to
+this central office. Once here, the wires are safeguarded in such
+manner that foreign currents from other wires or from lightning
+cannot disturb the system."
+
+We looked with intense interest at this huge electrical pulse that
+felt every change over so vast and rich an area.
+
+"Passing a big dividing board," he went on, "they are distributed
+and connected each in its place to the delicate tangent
+galvanometers and sensitive indicators you see in this room. These
+instantly announce the most minute change in the working of the
+current, and each office has a distinct separate metallic circuit.
+Why, even a hole as small as a lead pencil in anything protected
+would sound the alarm here."
+
+Kennedy nodded appreciatively.
+
+"You see," continued McLear, glad to be able to talk to one who
+followed him so closely, "it is another evidence of science
+finding for us greater security in the use of a tiny electric wire
+than in massive walls of steel and intricate lock devices. But
+here is a case in which, it seems, every known protection has
+failed. We can't afford to pass that by. If we have fallen down we
+want to know how, as well as to catch the burglar."
+
+"How are the signals given?" I asked.
+
+"Well, when the day's business is over, for instance, Schloss
+would swing the heavy safe doors together and over them place the
+doors of a wooden cabinet. That signals an alarm to us here. We
+answer it and if the proper signal is returned, all right. After
+that no one can tamper with the safe later in the night without
+sounding an alarm that would bring a quick investigation."
+
+"But suppose that it became necessary to open the safe before the
+next morning. Might not some trusted employee return to the
+office, open it, give the proper signals and loot the safe?"
+
+"No indeed," he answered confidently. "The very moment anyone
+touches the cabinet, the alarm is sounded. Even if the proper code
+signal is returned, it is not sufficient. A couple of our trusted
+men from the central office hustle around there anyhow and they
+don't leave until they are satisfied that everything is right. We
+have the authorized signatures on hand of those who are supposed
+to open the safe and a duplicate of one of them must be given or
+there is an arrest."
+
+McLear considered for a moment.
+
+"For instance, Schloss, like all the rest, was assigned a box in
+which was deposited a sealed envelope containing a key to the
+office and his own signature, in this case, since he alone knew
+the combination. Now, when an alarm is sounded, as it was last
+night, and the key removed to gain entrance to the office, a
+record is made and the key has to be sealed up again by Schloss. A
+report is also submitted showing when the signals are received and
+anything else that is worth recording. Last night our men found
+nothing wrong, apparently. But this morning we learn of the
+robbery."
+
+"The point is, then," ruminated Kennedy, "what happened in the
+interval between the ringing of the alarm and the arrival of the
+special officers? I think I'll drop around and look Schloss' place
+over," he added quietly, evidently eager to begin at the actual
+scene of the crime.
+
+On the door of the office to which McLear took us was one of those
+small blue plates which chance visitors to Maiden Lane must have
+seen often. To the initiated--be he crook or jeweler--this simple
+sign means that the merchant is a member of the Jewelers' Security
+Alliance, enough in itself, it would seem, to make the boldest
+burglar hesitate. For it is the motto of this organization to
+"get" the thief at any cost and at any time. Still, it had not
+deterred the burglar in this instance.
+
+"I know people are going to think it is a fake burglary,"
+exclaimed Schloss, a stout, prosperous-looking gem broker, as we
+introduced ourselves. "But over two hundred thousands dollars'
+worth of stones are gone," he half groaned. "Think of it, man," he
+added, "one of the greatest robberies since the Dead Line was
+established. And if they can get away with it, why, no one down
+here is protected any more. Half a billion dollars in jewels in
+Maiden Lane and John Street are easy prey for the cracksmen!"
+
+Staggering though the loss must have been to him, he had
+apparently recovered from the first shock of the discovery and had
+begun the fight to get back what had been lost.
+
+It was, as McLear had intimated, a most amazing burglary, too. The
+door of Schloss' safe was open when Kennedy and I arrived and
+found the excited jeweler nervously pacing the office. Surrounding
+the safe, I noticed a wooden framework constructed in such a way
+as to be a part of the decorative scheme of the office.
+
+Schloss banged the heavy doors shut.
+
+"There, that's just how it was--shut as tight as a drum. There was
+absolutely no mark of anyone tampering with the combination lock.
+And yet the safe was looted!"
+
+"How did you discover it?" asked Craig. "I presume you carry
+burglary insurance?"
+
+Schloss looked up quickly. "That's what I expected as a first
+question. No, I carried very little insurance. You see, I thought
+the safe, one of those new chrome steel affairs, was about
+impregnable. I never lost a moment's sleep over it; didn't think
+it possible for anyone to get into it. For, as you see, it is
+completely wired by the Hale Electric Protection--that wooden
+framework about it. No one could touch that when it was set
+without jangling a bell at the central office which would send men
+scurrying here to protect the place."
+
+"But they must have got past it," suggested Kennedy.
+
+"Yes--they must have. At least this morning I received the regular
+Hale report. It said that their wires registered last night as
+though some one was tampering with the safe. But by the time they
+got around, in less than five minutes, there was no one here,
+nothing seemed to be disturbed. So they set it down to induction
+or electrolysis, or something the matter with the wires. I got the
+report the first thing when I arrived here with my assistant,
+Muller."
+
+Kennedy was on his knees, going over the safe with a fine brush
+and some powder, looking now and then through a small magnifying
+glass.
+
+"Not a finger print," he muttered. "The cracksman must have worn
+gloves. But how did he get in? There isn't a mark of 'soup' having
+been used to blow it up, nor of a 'can-opener' to rip it open, if
+that were possible, nor of an electric or any other kind of
+drill."
+
+"I've read of those fellows who burn their way in," said Schloss.
+
+"But there is no hole," objected Kennedy, "not a trace of the use
+of thermit to burn the way in or of the oxyacetylene blowpipe to
+cut a piece out. Most extraordinary," he murmured.
+
+"You see," shrugged Schloss, "everyone will say it must have been
+opened by one who knew the combination. But I am the only one. I
+have never written it down or told anyone, not even Muller. You
+understand what I am up against?"
+
+"There's the touch system," I suggested. "You remember, Craig, the
+old fellow who used to file his finger tips to the quick until
+they were so sensitive that he could actually feel when he had
+turned the combination to the right plunger? Might not that
+explain the lack of finger prints also?" I added eagerly.
+
+"Nothing like that in this case, Walter," objected Craig
+positively. "This fellow wore gloves, all right. No, this safe has
+been opened and looted by no ordinarily known method. It's the
+most amazing case I ever saw in that respect--almost as if we had
+a cracksman in the fourth dimension to whom the inside of a closed
+cube is as accessible as is the inside of a plane square to us
+three dimensional creatures. It is almost incomprehensible."
+
+I fancied I saw Schloss' face brighten as Kennedy took this view.
+So far, evidently, he had run across only skepticism.
+
+"The stones were unset?" resumed Craig.
+
+"Mostly. Not all."
+
+"You would recognize some of them if you saw them?"
+
+"Yes indeed. Some could be changed only by re-cutting. Even some
+of those that were set were of odd cut and size--some from a
+diamond necklace which belonged to a--"
+
+There was something peculiar in both his tone and manner as he cut
+short the words.
+
+"To whom?" asked Kennedy casually.
+
+"Oh, once to a well-known woman in society," he said carefully.
+"It is mine, though, now--at least it was mine. I should prefer to
+mention no names. I will give a description of the stones."
+
+"Mrs. Lynn Moulton, for instance?" suggested Craig quietly.
+
+Schloss jumped almost as if a burglar alarm had sounded under his
+very ears. "How did you know? Yes--but it was a secret. I made a
+large loan on it, and the time has expired."
+
+"Why did she need money so badly?" asked Kennedy.
+
+"How should I know?" demanded Schloss.
+
+Here was a deepening mystery, not to be elucidated by continuing
+this line of inquiry with Schloss, it seemed.
+
+
+
+
+CHAPTER XVII
+
+THE PASTE REPLICA
+
+
+Carefully Craig was going over the office. Outside of the safe,
+there had apparently been nothing of value. The rest of the office
+was not even wired, and it seemed to have been Schloss' idea that
+the few thousands of burglary insurance amply protected him
+against such loss. As for the safe, its own strength and the
+careful wiring might well have been considered quite sufficient
+under any hitherto to-be-foreseen circumstances.
+
+A glass door, around the bend of a partition, opened from the
+hallway into the office and had apparently been designed with the
+object of making visible the safe so that anyone passing might see
+whether an intruder was tampering with it.
+
+Kennedy had examined the door, perhaps in the expectation of
+finding finger prints there, and was passing on to other things,
+when a change in his position caused his eye to catch a large oval
+smudge on the glass, which was visible when the light struck it at
+the right angle. Quickly he dusted it over with the powder, and
+brought out the detail more clearly. As I examined it, while Craig
+made preparations to cut out the glass to preserve it, it seemed
+to contain a number of minute points and several more or less
+broken parallel lines. The edges gradually trailed off into an
+indistinct faintness.
+
+Business, naturally, was at a standstill, and as we were working
+near the door, we could see that the news of Schloss' strange
+robbery had leaked out and was spreading rapidly. Scores of
+acquaintances in the trade stopped at the door to inquire about
+the rumor.
+
+To each, it seemed that Morris Muller, the working jeweler
+employed by Schloss, repeated the same story.
+
+"Oh," he said, "it is a big loss--yes--but big as it is, it will
+not break Mr. Schloss. And," he would add with the tradesman's
+idea of humor, "I guess he has enough to play a game of poker--
+eh?"
+
+"Poker?" asked Kennedy smiling. "Is he much of a player?"
+
+"Yes. Nearly every night with his friends he plays."
+
+Kennedy made a mental note of it. Evidently Schloss trusted Muller
+implicitly. He seemed like a partner, rather than an employee,
+even though he had not been entrusted with the secret combination.
+
+Outside, we ran into city detective Lieutenant Winters, the
+officer who was stationed at the Maiden Lane post, guarding that
+famous section of the Dead Line established by the immortal Byrnes
+at Fulton Street, below which no crook was supposed to dare even
+to be seen. Winters had been detailed on the case.
+
+"You have seen the safe in there?" asked Kennedy, as he was
+leaving to carry on his investigation elsewhere.
+
+Winters seemed to be quite as skeptical as Schloss had intimated
+the public would be. "Yes," he replied, "there's been an epidemic
+of robbery with the dull times--people who want to collect their
+burglary insurance, I guess."
+
+"But," objected Kennedy, "Schloss carried so little."
+
+"Well, there was the Hale Protection. How about that?"
+
+Craig looked up quickly, unruffled by the patronizing air of the
+professional toward the amateur detective.
+
+"What is your theory?" he asked. "Do you think he robbed himself?"
+
+Winters shrugged his shoulders. "I've been interested in Schloss
+for some time," he said enigmatically. "He has had some pretty
+swell customers. I'll keep you wised up, if anything happens," he
+added in a burst of graciousness, walking off.
+
+On the way to the subway, we paused again to see McLear.
+
+"Well," he asked, "what do you think of it, now?"
+
+"All most extraordinary," ruminated Craig. "And the queerest
+feature of all is that the chief loss consists of a diamond
+necklace that belonged once to Mrs. Antoinette Moulton."
+
+"Mrs. Lynn Moulton?" repeated McLear.
+
+"The same," assured Kennedy.
+
+McLear appeared somewhat puzzled. "Her husband is one of our old
+subscribers," he pursued. "He is a lawyer on Wall Street and quite
+a gem collector. Last night his safe was tampered with, but this
+morning he reports no loss. Not half an hour ago he had us on the
+wire congratulating us on scaring off the burglars, if there had
+been any."
+
+"What is your opinion," I asked. "Is there a gang operating?"
+
+"My belief is," he answered, reminiscently of his days on the
+detective force, "that none of the loot will be recovered until
+they start to 'fence' it. That would be my lay--to look for the
+fence. Why, think of all the big robberies that have been pulled
+off lately. Remember," he went on, "the spoils of a burglary
+consist generally of precious stones. They are not currency. They
+must be turned into currency--or what's the use of robbery?
+
+"But merely to offer them for sale at an ordinary jeweler's would
+be suspicious. Even pawnbrokers are on the watch. You see what I
+am driving at? I think there is a man or a group of men whose
+business it is to pay cash for stolen property and who have ways
+of returning gems into the regular trade channels. In all these
+robberies we get a glimpse of as dark and mysterious a criminal as
+has ever been recorded. He may be--anybody. About his legitimacy,
+I believe, no question has ever been raised. And, I tell you, his
+arrest is going to create a greater sensation than even the
+remarkable series of robberies that he has planned or made
+possible. The question is, to my mind, who is this fence?"
+
+McLear's telephone rang and he handed the instrument to Craig.
+
+"Yes, this is Professor Kennedy," answered Craig. "Oh, too bad
+you've had to try all over to get me. I've been going from one
+place to another gathering clues and have made good progress,
+considering I've hardly started. Why--what's the matter? Really?"
+
+An interval followed, during which McLear left to answer a
+personal call on another wire.
+
+As Kennedy hung up the receiver, his face wore a peculiar look.
+"It was Mrs. Moulton," he blurted out. "She thinks that her
+husband has found out that the necklace is paste."
+
+"How?" I asked.
+
+"The paste replica is gone from her wall safe in the Deluxe."
+
+I turned, startled at the information. Even Kennedy himself was
+perplexed at the sudden succession of events. I had nothing to
+say.
+
+Evidently, however, his rule was when in doubt play a trump, for,
+twenty minutes later found us in the office of Lynn Moulton, the
+famous corporation lawyer, in Wall Street.
+
+Moulton was a handsome man of past fifty with a youthful face
+against his iron gray hair and mustache, well dressed, genial, a
+man who seemed keenly in love with the good things of life.
+
+"It is rumored," began Kennedy, "that an attempt was made on your
+safe here at the office last night."
+
+"Yes," he admitted, taking off his glasses and polishing them
+carefully. "I suppose there is no need of concealment, especially
+as I hear that a somewhat similar attempt was made on the safe of
+my friend Herman Schloss in Maiden Lane."
+
+"You lost nothing?"
+
+Moulton put his glasses on and looked Kennedy in the face frankly.
+
+"Nothing, fortunately," he said, then went on slowly. "You see, in
+my later years, I have been something of a collector of precious
+stones myself. I don't wear them, but I have always taken the
+keenest pleasure in owning them and when I was married it gave me
+a great deal more pleasure to have them set in rings, pendants,
+tiaras, necklaces, and other forms for my wife."
+
+He had risen, with the air of a busy man who had given the subject
+all the consideration he could afford and whose work proceeded
+almost by schedule. "This morning I found my safe tampered with,
+but, as I said, fortunately something must have scared off the
+burglars."
+
+He bowed us out politely. What was the explanation, I wondered. It
+seemed, on the face of things, that Antoinette Moulton feared her
+husband. Did he know something else already, and did she know he
+knew? To all appearances he took it very calmly, if he did know.
+Perhaps that was what she feared, his very calmness.
+
+"I must see Mrs. Moulton again," remarked Kennedy, as we left.
+
+The Moultons lived, we found, in one of the largest suites of a
+new apartment hotel, the Deluxe, and in spite of the fact that our
+arrival had been announced some minutes before we saw Mrs.
+Moulton, it was evident that she had been crying hysterically over
+the loss of the paste jewels and what it implied.
+
+"I missed it this morning, after my return from seeing you," she
+replied in answer to Craig's inquiry, then added, wide-eyed with
+alarm, "What shall I do? He must have opened the wall safe and
+found the replica. I don't dare ask him point-blank."
+
+"Are you sure he did it?" asked Kennedy, more, I felt, for its
+moral effect on her than through any doubt in his own mind.
+
+"Not sure. But then the wall safe shows no marks, and the replica
+is gone."
+
+"Might I see your jewel case?" he asked.
+
+"Surely. I'll get it. The wall safe is in Lynn's room. I shall
+probably have to fuss a long time with the combination."
+
+In fact she could not have been very familiar with it for it took
+several minutes before she returned. Meanwhile, Kennedy, who had
+been drumming absently on the arms of his chair, suddenly rose and
+walked quietly over to a scrap basket that stood beside an
+escritoire. It had evidently just been emptied, for the rooms must
+have been cleaned several hours before. He bent down over it and
+picked up two scraps of paper adhering to the wicker work. The
+rest had evidently been thrown away.
+
+I bent over to read them. One was:
+
+ --rest Nettie--
+ --dying to see--
+
+The other read:
+
+ --cherche to-d
+ --love and ma
+ --rman.
+
+What did it mean? Hastily, I could fill in "Dearest Nettie," and
+"I am dying to see you." Kennedy added, "The Recherche to-day,"
+that being the name of a new apartment uptown, as well as "love
+and many kisses." But "--rman"--what did that mean? Could it be
+Herman--Herman Schloss?
+
+She was returning and we resumed our seats quickly.
+
+Kennedy took the jewel case from her and examined it carefully.
+There was not a mark on it.
+
+"Mrs. Moulton," he said slowly, rising and handing it back to her,
+"have you told me all?"
+
+"Why--yes," she answered.
+
+Kennedy shook his head gravely.
+
+"I'm afraid not. You must tell me everything."
+
+"No--no," she cried vehemently, "there is nothing more."
+
+We left and outside the Deluxe he paused, looked about, caught
+sight of a taxicab and hailed it.
+
+"Where?" asked the driver.
+
+"Across the street," he said, "and wait. Put the window in back of
+you down so I can talk. I'll tell you where to go presently. Now,
+Walter, sit back as far as you can. This may seem like an
+underhand thing to do, but we've got to get what that woman won't
+tell us or give up the case."
+
+Perhaps half an hour we waited, still puzzling over the scraps of
+paper. Suddenly I felt a nudge from Kennedy. Antoinette Moulton
+was standing in the doorway across the street. Evidently she
+preferred not to ride in her own car, for a moment later she
+entered a taxicab.
+
+"Follow that black cab," said Kennedy to our driver.
+
+Sure enough, it stopped in front of the Recherche Apartments and
+Mrs. Moulton stepped out and almost ran in.
+
+We waited a moment, then Kennedy followed. The elevator that had
+taken her up had just returned to the ground floor.
+
+"The same floor again," remarked Kennedy, jauntily stepping in and
+nodding familiarly to the elevator boy.
+
+Then he paused suddenly, looked at his watch, fixed his gaze
+thoughtfully on me an instant, and exclaimed. "By George--no. I
+can't go up yet. I clean forgot that engagement at the hotel. One
+moment, son. Let us out. We'll be back again."
+
+Considerably mystified, I followed him to the sidewalk.
+
+"You're entitled to an explanation," he laughed catching my
+bewildered look as he opened the cab door. "I didn't want to go up
+now while she is there, but I wanted to get on good terms with
+that boy. We'll wait until she comes down, then go up."
+
+"Where?" I asked.
+
+"That's what I am going through all this elaborate preparation to
+find out. I have no more idea than you have."
+
+It could not have been more than twenty minutes later when Mrs.
+Moulton emerged rather hurriedly, and drove away.
+
+While we had been waiting I had observed a man on the other side
+of the street who seemed unduly interested in the Recherche, too,
+for he had walked up and down the block no less than six times.
+Kennedy saw him, and as he made no effort to follow Mrs. Moulton,
+Kennedy did not do so either. In fact a little quick glance which
+she had given at our cab had raised a fear that she might have
+discovered that she was being followed.
+
+Kennedy and I paid off our cabman and sauntered into the Recherche
+in the most debonair manner we could assume.
+
+"Now, son, we'll go up," he said to the boy who, remembering us,
+and now not at all clear in his mind that he might not have seen
+us before that, whisked us to the tenth floor.
+
+"Let me see," said Kennedy, "it's number one hundred and--er---"
+
+"Three," prompted the boy.
+
+He pressed the buzzer and a neatly dressed colored maid responded.
+
+"I had an appointment here with Mrs. Moulton this morning,"
+remarked Kennedy.
+
+"She has just gone," replied the maid, off her guard.
+
+"And was to meet Mr. Schloss here in half an hour," he added
+quickly.
+
+It was the maid's turn to look surprised.
+
+"I didn't think he was to be here," she said. "He's had some--"
+
+"Trouble at the office," supplied Kennedy. "That's what it was
+about. Perhaps he hasn't been able to get away yet. But I had the
+appointment. Ah, I see a telephone in the hall. May I?"
+
+He had stepped politely in, and by dint of cleverly keeping his
+finger on the hook in the half light, he carried on a one-sided
+conversation with himself long enough to get a good chance to look
+about.
+
+There was an air of quiet and refinement about the apartment in
+the Recherche. It was darkened to give the little glowing electric
+bulbs in their silken shades a full chance to simulate right. The
+deep velvety carpets were noiseless to the foot, and the
+draperies, the pictures, the bronzes, all bespoke taste.
+
+But the chief objects of interest to Craig were the little square
+green baize-covered tables on one of which lay neatly stacked a
+pile of gilt-edged cards and a mahogany box full of ivory chips of
+red, white and blue.
+
+It was none of the old-time gambling places, like Danfield's, with
+its steel door which Craig had once cut through with an
+oxyacetylene blowpipe in order to rescue a young spendthrift from
+himself.
+
+Kennedy seemed perfectly well satisfied merely with a cursory view
+of the place, as he hung up the receiver and thanked the maid
+politely for allowing him to use it.
+
+"This is up-to-date gambling in cleaned-up New York," he remarked
+as we waited for the elevator to return for us. "And the worst of
+it all is that it gets the women as well as the men. Once they are
+caught in the net, they are the most powerful lure to men that the
+gamblers have yet devised."
+
+We rode down in silence, and as we went down the steps to the
+street, I noticed the man whom we had seen watching the place,
+lurking down at the lower corner. Kennedy quickened his pace and
+came up behind him.
+
+"Why, Winters!" exclaimed Craig. "You here?"
+
+"I might say the same to you," grinned the detective not
+displeased evidently that our trail had crossed his. "I suppose
+you are looking for Schloss, too. He's up in the Recherche a great
+deal, playing poker. I understand he owns an interest in the game
+up there."
+
+Kennedy nodded, but said nothing.
+
+"I just saw one of the cappers for the place go out before you
+went in."
+
+"Capper?" repeated Kennedy surprised. "Antoinette Moulton a
+steerer for a gambling joint? What can a rich society woman have
+to do with a place like that or a man like Schloss?"
+
+Winters smiled sardonically. "Society ladies to-day often get into
+scrapes of which their husbands know nothing," he remarked. "You
+didn't know before that Antoinette Moulton, like many of her
+friends in the smart set, was a gambler--and loser--did you?"
+
+Craig shook his head. He had more of human than scientific
+interest in a case of a woman of her caliber gone wrong.
+
+"But you must have read of the famous Moulton diamonds?"
+
+"Yes," said Craig, blankly, as if it were all news to him.
+
+"Schloss has them--or at least had them. The jewels she wore at
+the opera this winter were paste, I understand."
+
+"Does Moulton play?" he asked.
+
+"I think so--but not here, naturally. In a way, I suppose, it is
+his fault. They all do it. The example of one drives on another."
+
+Instantly there flashed over my mind a host of possibilities.
+Perhaps, after all, Winters had been right. Schloss had taken this
+way to make sure of the jewels so that she could not redeem them.
+Suddenly another explanation crowded that out. Had Mrs. Moulton
+robbed the safe herself, or hired some one else to do it for her,
+and had that person gone back on her?
+
+Then a horrid possibility occurred to me. Whatever Antoinette
+Moulton may have been and done, some one must have her in his
+power. What a situation for the woman! My sympathy went out to her
+in her supreme struggle. Even if it had been a real robbery,
+Schloss might easily recover from it. But for her every event
+spelled ruin and seemed only to be bringing that ruin closer.
+
+We left Winters, still watching on the trail of Schloss, and went
+on uptown to the laboratory.
+
+
+
+
+CHAPTER XVIII
+
+THE BURGLAR'S MICROPHONE
+
+
+That night I was sitting, brooding over the case, while Craig was
+studying a photograph which he made of the smudge on the glass
+door down at Schloss'. He paused in his scrutiny of the print to
+answer the telephone.
+
+"Something has happened to Schloss," he exclaimed seizing his hat
+and coat. "Winters has been watching him. He didn't go to the
+Recherche. Winters wants me to meet him at a place several blocks
+below it Come on. He wouldn't say over the wire what it was.
+Hurry."
+
+We met Winters in less than ten minutes at the address he had
+given, a bachelor apartment in the neighborhood of the Recherche.
+
+"Schloss kept rooms here," explained Winters, hurrying us quickly
+upstairs. "I wanted you to see before anyone else."
+
+As we entered the large and luxuriously furnished living room of
+the jeweler's suite, a gruesome sight greeted us.
+
+There lay Schloss on the floor, face down, in a horribly contorted
+position. In one hand, clenched under him partly, the torn sleeve
+of a woman's dress was grasped convulsively. The room bore
+unmistakable traces of a violent struggle, but except for the
+hideous object on the floor was vacant.
+
+Kennedy bent down over him. Schloss was dead. In a corner, by the
+door, stood a pile of grips, stacked up, packed, and undisturbed.
+
+Winters who had been studying the room while we got our bearings
+picked up a queer-looking revolver from the floor. As he held it
+up I could see that along the top of the barrel was a long
+cylinder with a ratchet or catch at the butt end. He turned it
+over and over carefully.
+
+"By George," he muttered, "it has been fired off."
+
+Kennedy glanced more minutely at the body. There was not a mark on
+it. I stared about vacantly at the place where Winters had picked
+the thing up.
+
+"Look," I cried, my eye catching a little hole in the baseboard of
+the woodwork near it.
+
+"It must have fallen and exploded on the floor," remarked Kennedy.
+"Let me see it, Winters."
+
+Craig held it at arm's length and pulled the catch. Instead of an
+explosion, there came a cone of light from the top of the gun. As
+Kennedy moved it over the wall, I saw in the center of the circle
+of light a dark spot.
+
+"A new invention," Craig explained. "All you need to do is to move
+it so that little dark spot falls directly on an object. Pull the trigger--
+the bullet strikes the dark spot. Even a nervous and unskilled
+marksman becomes a good shot in the dark. He can even shoot
+from behind the protection of something--and hit accurately."
+
+It was too much for me. I could only stand and watch Kennedy as he
+deftly bent over Schloss again and placed a piece of chemically
+prepared paper flat on the forehead of the dead man.
+
+When he withdrew it, I could see that it bore marks of the lines
+on his head. Without a word, Kennedy drew from his pocket a print
+of the photograph of the smudge on Schloss' door.
+
+"It is possible," he said, half to himself, "to identify a person
+by means of the arrangement of the sweat glands or pores.
+Poroscopy, Dr. Edmond Locard, director of the Police Laboratory at
+Lyons, calls it. The shape, arrangement, number per square
+centimeter, all vary in different individuals. Besides, here we
+have added the lines of the forehead."
+
+He was studying the two impressions intensely. When he looked up
+from his examination, his face wore a peculiar expression.
+
+"This is not the head which was placed so close to the glass of
+the door of Schloss' office, peering through, on the night of the
+robbery, in order to see before picking the lock whether the
+office was empty and everything ready for the hasty attack on the
+safe."
+
+"That disposes of my theory that Schloss robbed himself," remarked
+Winters reluctantly. "But the struggle here, the sleeve of the
+dress, the pistol--could he have been shot?"
+
+"No, I think not," considered Kennedy. "It looks to me more like a
+case of apoplexy."
+
+"What shall we do?" asked Winters. "Far from clearing anything up,
+this complicates it."
+
+"Where's Muller?" asked Kennedy. "Does he know? Perhaps he can
+shed some light on it."
+
+The clang of an ambulance bell outside told that the aid summoned
+by Winters had arrived.
+
+We left the body in charge of the surgeon and of a policeman who
+arrived about the same time, and followed Winters.
+
+Muller lived in a cheap boarding house in a shabbily respectable
+street downtown, and without announcing ourselves we climbed the
+stairs to his room. He looked up surprised but not disconcerted as
+we entered.
+
+"What's the matter?" he asked.
+
+"Muller," shot out Winters, "we have just found Mr. Schloss dead!"
+
+"D-dead!" he stammered.
+
+The man seemed speechless with horror.
+
+"Yes, and with his grips packed as if to run away."
+
+Muller looked dazedly from one of us to the other, but shut up
+like a clam.
+
+"I think you had better come along with us as a material witness,"
+burst out Winters roughly.
+
+Kennedy said nothing, leaving that sort of third degree work to
+the detective. But he was not idle, as Winters tried to extract
+more than the monosyllables, "I don't know," in answer to every
+inquiry of Muller about his employer's life and business.
+
+A low exclamation from Craig attracted my attention from Winters.
+In a corner he had discovered a small box and had opened it.
+Inside was a dry battery and a most peculiar instrument, something
+like a little flat telephone transmitter yet attached by wires to
+earpieces that fitted over the head after the manner of those of a
+wireless detector.
+
+"What's this?" asked Kennedy, dangling it before Muller.
+
+He looked at it phlegmatically. "A deaf instrument I have been
+working on," replied the jeweler. "My hearing is getting poor."
+
+Kennedy looked hastily from the instrument to the man.
+
+"I think I'll take it along with us," he said quietly.
+
+Winters, true to his instincts, had been searching Muller in the
+meantime. Besides the various assortment that a man carries in his
+pockets usually, including pens, pencils, notebooks, a watch, a
+handkerchief, a bunch of keys, one of which was large enough to
+open a castle, there was a bunch of blank and unissued pawn-tickets
+bearing the name, "Stein's One Per Cent. a Month Loans," and an
+address on the Bowery.
+
+Was Muller the "fence" we were seeking, or only a tool for the
+"fence" higher up? Who was this Stein?
+
+What it all meant I could only guess. It was a far cry from the
+wealth of Diamond Lane to a dingy Bowery pawnshop, even though
+pawnbroking at one per cent. a month--and more, on the side--pays.
+I knew, too, that diamonds are hoarded on the East Side as nowhere
+else in the world, outside of India. It was no uncommon thing, I
+had heard, for a pawnbroker whose shop seemed dirty and greasy to
+the casual visitor to have stored away in his vault gems running
+into the hundreds of thousands of dollars.
+
+"Mrs. Moulton must know of this," remarked Kennedy. "Winters, you
+and Jameson bring Muller along. I am going up to the Deluxe."
+
+I must say that I was surprised at finding Mrs. Moulton there.
+Outside the suite Winters and I waited with the unresisting
+Muller, while Kennedy entered. But through the door which he left
+ajar I could hear what passed.
+
+"Mrs. Moulton," he began, "something terrible has happened--"
+
+He broke off, and I gathered that her pale face and agitated
+manner told him that she knew already.
+
+"Where is Mr. Moulton?" he went on, changing his question.
+
+"Mr. Moulton is at his office," she answered tremulously. "He
+telephoned while I was out that he had to work to-night. Oh, Mr.
+Kennedy--he knows--he knows. I know it. He has avoided me ever
+since I missed the replica from-"
+
+"Sh!" cautioned Craig. He had risen and gone to the door.
+
+"Winters," he whispered, "I want you to go down to Lynn Moulton's
+office. Meanwhile Jameson can take care of Muller. I am going over
+to that place of Stein's presently. Bring Moulton up there. You
+will wait here, Walter, for the present," he nodded.
+
+He returned to the room where I could hear her crying softly.
+
+"Now, Mrs. Moulton," he said gently, "I'm afraid I must trouble
+you to go with me. I am going over to a pawnbroker's on the
+Bowery."
+
+"The Bowery?" she repeated, with a genuinely surprised shudder.
+"Oh, no, Mr. Kennedy. Don't ask me to go anywhere to-night. I am--
+I am in no condition to go anywhere--to do anything--I--"
+
+"But you must," said Kennedy in a low voice.
+
+"I can't. Oh--have mercy on me. I am terribly upset. You--"
+
+"It is your duty to go, Mrs. Moulton," he repeated.
+
+"I don't understand." she murmured. "A pawnbroker's?"
+
+"Come," urged Kennedy, not harshly but firmly, then, as she held
+back, added, playing a trump card, "We must work quickly. In his
+hands we found the fragments of a torn dress. When the police--"
+
+She uttered a shriek. A glance had told her, if she had deceived
+herself before, that Kennedy knew her secret.
+
+Antoinette Moulton was standing before him, talking rapidly.
+
+"Some one has told Lynn. I know it. There is nothing now that I
+can conceal. If you had come half an hour later you would not have
+found me. He had written to Mr. Schloss, threatening him that if
+he did not leave the country he would shoot him at sight. Mr.
+Schloss showed me the letter.
+
+"It had come to this. I must either elope with Schloss, or lose
+his aid. The thought of either was unendurable. I hated him--yet
+was dependent on him.
+
+"To-night I met him, in his empty apartment, alone. I knew that he
+had what was left of his money with him, that everything was
+packed up. I went prepared. I would not elope. My plan was no less
+than to make him pay the balance on the necklace that he had lost-
+-or to murder him.
+
+"I carried a new pistol in my muff, one which Lynn had just
+bought. I don't know how I did it. I was desperate.
+
+"He told me he loved me, that Lynn did not, never had--that Lynn
+had married me only to show off his wealth and diamonds, to give
+him a social! position--that I was merely a--a piece of property--
+a dummy.
+
+"He tried to kiss me. It was revolting. I struggled away from him.
+
+"And in the struggle, the revolver fell from my muff and exploded
+on the floor.
+
+"At once he was aflame with suspicion.
+
+"'So--it's murder you want!' he shouted. 'Well, murder it shall
+be!'
+
+"I saw death in his eye as he seized my arm. I was defenseless
+now. The old passion came over him. Before he killed--he--would
+have his way with me.
+
+"I screamed. With a wild effort I twisted away from him.
+
+"He raised his hand to strike me, I saw his eyes, glassy. Then he
+sank back--fell to the floor--dead of apoplexy--dead of his
+furious emotions.
+
+"I fled.
+
+"And now you have found me."
+
+She had turned, hastily, to leave the room. Kennedy blocked the
+door.
+
+"Mrs. Moulton," he said firmly, "listen to me. What was the first
+question you asked me? 'Can I trust you?' And I told you you
+could. This is no time for--for suicide." He shot the word out
+bluntly. "All may not be lost. I have sent for your husband.
+Muller is outside."
+
+"Muller?" she cried. "He made the replica."
+
+"Very well. I am going to clear this thing up. Come. You MUST."
+
+It was all confused to me, the dash in a car to the little
+pawnbroker's on the first floor of a five-story tenement, the
+quick entry into the place by one of Muller's keys.
+
+Over the safe in back was a framework like that which had covered
+Schloss' safe. Kennedy tore it away, regardless of the alarm which
+it must have sounded. In a moment he was down before it on his
+knees.
+
+"This is how Schloss' safe was opened so quickly," he muttered,
+working feverishly. "Here is some of their own medicine."
+
+He had placed the peculiar telephone-like transmitter close to the
+combination lock and was turning the combination rapidly.
+
+Suddenly he rose, gave the bolts a twist, and the ponderous doors
+swung open.
+
+"What is it?" I asked eagerly.
+
+"A burglar's microphone," he answered, hastily looking over the
+contents of the safe. "The microphone is now used by burglars for
+picking combination locks. When you turn the lock, a slight sound
+is made when the proper number comes opposite the working point.
+It can be heard sometimes by a sensitive ear, although it is
+imperceptible to most persons. But by using a microphone it is an
+easy matter to hear the sounds which allow of opening the lock."
+
+He had taken a yellow chamois bag out of the safe and opened it.
+
+Inside sparkled the famous Moulton diamonds. He held them up--in
+all their wicked brilliancy. No one spoke.
+
+Then he took another yellow bag, more dirty and worn than the
+first. As he opened it, Mrs. Moulton could restrain herself no
+longer.
+
+"The replica!" she cried. "The replica!"
+
+Without a word, Craig handed the real necklace to her. Then he
+slipped the paste jewels into the newer of the bags and restored
+both it and the empty one to their places, banged shut the door of
+the safe, and replaced the wooden screen.
+
+"Quick!" he said to her, "you have still a minute to get away.
+Hurry--anywhere--away--only away!"
+
+The look of gratitude that came over her face, as she understood
+the full meaning of it was such as I had never seen before.
+
+"Quick!" he repeated.
+
+It was too late.
+
+"For God's sake, Kennedy," shouted a voice at the street door,
+"what are you doing here?"
+
+It was McLear himself. He had come with the Hale patrol, on his
+mettle now to take care of the epidemic of robberies.
+
+Before Craig could reply a cab drew up with a rush at the curb and
+two men, half fighting, half cursing, catapulted themselves into
+the shop.
+
+They were Winters and Moulton.
+
+Without a word, taking advantage of the first shock of surprise,
+Kennedy had clapped a piece of chemical paper on the foreheads of
+Mrs. Moulton, then of Moulton, and on Muller's. Oblivious to the
+rest of us, he studied the impressions in the full light of the
+counter.
+
+Moulton was facing his wife with a scornful curl of the lip.
+
+"I've been told of the paste replica--and I wrote Schloss that I'd
+shoot him down like the dog he is, you--you traitress," he hissed.
+
+She drew herself up scornfully.
+
+"And I have been told why you married me--to show off your wicked
+jewels and help you in your--"
+
+"You lie!" he cried fiercely. "Muller--some one--open this safe--
+whosever it is. If what I have been told is true, there is in it
+one new bag containing the necklace. It was stolen from Schloss to
+whom you sold my jewels. The other old bag, stolen from me,
+contains the paste replica you had made to deceive me."
+
+It was all so confused that I do not know how it happened. I think
+it was Muller who opened the safe.
+
+"There is the new yellow bag," cried Moulton, "from Schloss' own
+safe. Open it."
+
+McLear had taken it. He did so. There sparkled not the real gems,
+but the replica.
+
+"The devil!" Moulton exclaimed, breaking from Winters and seizing
+the old bag.
+
+He tore it open and--it was empty.
+
+"One moment," interrupted Kennedy, looking up quietly from the
+counter. "Seal that safe again, McLear. In it are the Schloss
+jewels and the products of half a dozen other robberies which the
+dupe Muller--or Stein, as you please--pulled off, some as a blind
+to conceal the real criminal. You may have shown him how to leave
+no finger prints, but you yourself have left what is just as good-
+-your own forehead print. McLear--you were right. There's your
+criminal--Lynn Moulton, professional fence, the brains of the
+thing."
+
+
+
+
+CHAPTER XIX
+
+THE GERM LETTER
+
+
+Lynn Moulton made no fight and Kennedy did not pursue the case,
+for, with the rescue of Antoinette Moulton, his interest ceased.
+
+Blackmail takes various forms, and the Moulton affair was only one
+phase of it. It was not long before we had to meet a much stranger
+attempt.
+
+"Read the letter, Professor Kennedy. Then I will tell you the
+sequel."
+
+Mrs. Hunter Blake lay back in the cushions of her invalid chair in
+the sun parlor of the great Blake mansion on Riverside Drive,
+facing the Hudson with its continuous reel of maritime life framed
+against the green-hilled background of the Jersey shore.
+
+Her nurse, Miss Dora Sears, gently smoothed out the pillows and
+adjusted them so that the invalid could more easily watch us. Mrs.
+Blake, wealthy, known as a philanthropist, was not an old woman,
+but had been for years a great sufferer from rheumatism.
+
+I watched Miss Sears eagerly. Full-bosomed, fine of face and
+figure, she was something more than a nurse; she was a companion.
+She had bright, sparkling black eyes and an expression about her
+well-cut mouth which made one want to laugh with her. It seemed to
+say that the world was a huge joke and she invited you to enjoy
+the joke with her.
+
+Kennedy took the letter which Miss Sears proffered him, and as he
+did so I could not help noticing her full, plump forearm on which
+gleamed a handsome plain gold bracelet. He spread the letter out
+on a dainty wicker table in such a way that we both could see it.
+
+We had been summoned over the telephone to the Blake mansion by
+Reginald Blake, Mrs. Blake's eldest son. Reginald had been very
+reticent over the reason, but had seemed very anxious and
+insistent that Kennedy should come immediately.
+
+Craig read quickly and I followed him, fascinated by the letter
+from its very opening paragraph.
+
+"Dear Madam," it began. "Having received my diploma as doctor of
+medicine and bacteriology at Heidelberg in 1909, I came to the
+United States to study a most serious disease which is prevalent
+in several of the western mountain states."
+
+So far, I reflected, it looked like an ordinary appeal for aid.
+The next words, however, were queer: "I have four hundred persons
+of wealth on my list. Your name was--"
+
+Kennedy turned the page. On the next leaf of the letter sheet was
+pasted a strip of gelatine. The first page had adhered slightly to
+the gelatine.
+
+"Chosen by fate," went on the sentence ominously.
+
+"By opening this letter," I read, "you have liberated millions of
+the virulent bacteria of this disease. Without a doubt you are
+infected by this time, for no human body is impervious to them,
+and up to the present only one in one hundred has fully recovered
+after going through all its stages."
+
+I gasped. The gelatine had evidently been arranged so that when
+the two sheets were pulled apart, the germs would be thrown into
+the air about the person opening the letter. It was a very
+ingenious device.
+
+The letter continued, "I am happy to say, however, that I have a
+prophylactic which will destroy any number of these germs if used
+up to the ninth day. It is necessary only that you should place
+five thousand dollars in an envelope and leave it for me to be
+called for at the desk of the Prince Henry Hotel. When the
+messenger delivers the money to me, the prophylactic will be sent
+immediately.
+
+"First of all, take a match and burn this letter to avoid
+spreading the disease. Then change your clothes and burn the old
+ones. Enclosed you will find in a germ-proof envelope an exact
+copy of this letter. The room should then be thoroughly fumigated.
+Do not come into close contact with anyone near and dear to you
+until you have used the prophylactic. Tell no one. In case you do,
+the prophylactic will not be sent under any circumstances. Very
+truly yours, DR. HANS HOPF."
+
+"Blackmail!" exclaimed Kennedy, looking intently again at the
+gelatine on the second page, as I involuntarily backed away and
+held my breath.
+
+"Yes, I know," responded Mrs. Blake anxiously, "but is it true?"
+
+There could be no doubt from the tone of her voice that she more
+than half believed that it was true.
+
+"I cannot say--yet," replied Craig, still cautiously scanning the
+apparently innocent piece of gelatine on the original letter which
+Mrs. Blake had not destroyed. "I shall have to keep it and examine
+it."
+
+On the gelatine I could see a dark mass which evidently was
+supposed to contain the germs.
+
+"I opened the letter here in this room," she went on. "At first I
+thought nothing of it. But this morning, when Buster, my prize
+Pekinese, who had been with me, sitting on my lap at the time, and
+closer to the letter even than I was, when Buster was taken
+suddenly ill, I--well, I began to worry."
+
+She finished with a little nervous laugh, as people will to hide
+their real feelings.
+
+"I should like to see the dog," remarked Kennedy simply.
+
+"Miss Sears," asked her mistress, "will you get Buster, please?"
+
+The nurse left the room. No longer was there the laughing look on
+her face. This was serious business.
+
+A few minutes later she reappeared, carrying gingerly a small dog
+basket. Mrs. Blake lifted the lid. Inside was a beautiful little
+"Peke," and it was easy to see that Buster was indeed ill.
+
+"Who is your doctor?" asked Craig, considering.
+
+"Dr. Rae Wilson, a very well-known woman physician."
+
+Kennedy nodded recognition of the name. "What does she say?" he
+asked, observing the dog narrowly.
+
+"We haven't told anyone, outside, of it yet," replied Mrs. Blake.
+"In fact until Buster fell sick, I thought it was a hoax."
+
+"You haven't told anyone?"
+
+"Only Reginald and my daughter Betty. Betty is frantic--not with
+fear for herself, but with fear for me. No one can reassure her.
+In fact it was as much for her sake as anyone's that I sent for
+you. Reginald has tried to trace the thing down himself, but has
+not succeeded."
+
+She paused. The door opened and Reginald Blake entered. He was a
+young fellow, self confident and no doubt very efficient at the
+new dances, though scarcely fitted to rub elbows with a cold world
+which, outside of his own immediate circle, knew not the name of
+Blake. He stood for a moment regarding us through the smoke of his
+cigarette.
+
+"Tell me just what you have done," asked Kennedy of him as his
+mother introduced him, although he had done the talking for her
+over the telephone.
+
+"Done?" he drawled. "Why, as soon as mother told me of the letter,
+I left an envelope up at the Prince Henry, as it directed."
+
+"With the money?" put in Craig quickly.
+
+"Oh, no--just as a decoy."
+
+"Yes. What happened?"
+
+"Well, I waited around a long time. It was far along in the day
+when a woman appeared at the desk. I had instructed the clerk to
+be on the watch for anyone who asked for mail addressed to a Dr.
+Hopf. The clerk slammed the register. That was the signal. I moved
+up closer."
+
+"What did she look like?" asked Kennedy keenly.
+
+"I couldn't see her face. But she was beautifully dressed, with a
+long light flowing linen duster, a veil that hid her features and
+on her hands and arms a long pair of motoring doeskin gloves. By
+George, she was a winner--in general looks, though. Well,
+something about the clerk, I suppose, must have aroused her
+suspicions. For, a moment later, she was gone in the crowd.
+Evidently she had thought of the danger and had picked out a time
+when the lobby would be full and everybody busy. But she did not
+leave by the front entrance through which she entered. I concluded
+that she must have left by one of the side street carriage doors."
+
+"And she got away?"
+
+"Yes. I found that she asked one of the boys at the door to crank
+up a car standing at the curb. She slid into the seat, and was off
+in a minute."
+
+Kennedy said nothing. But I knew that he was making a mighty
+effort to restrain comment on the bungling amateur detective work
+of the son of our client.
+
+Reginald saw the look on his face. "Still," he hastened, "I got
+the number of the car. It was 200859 New York."
+
+"You have looked it up?" queried Kennedy quickly.
+
+"I didn't need to do it. A few minutes later Dr. Rae Wilson
+herself came out--storming like mad. Her car had been stolen at
+the very door of the hotel by this woman with the innocent aid of
+the hotel employees."
+
+Kennedy was evidently keenly interested. The mention of the stolen
+car had apparently at once suggested an idea to him.
+
+"Mrs. Blake," he said, as he rose to go, "I shall take this letter
+with me. Will you see that Buster is sent up to my laboratory
+immediately?"
+
+She nodded. It was evident that Buster was a great pet with her
+and that it was with difficulty she kept from smoothing his silky
+coat.
+
+"You--you won't hurt Buster?" she pleaded.
+
+"No. Trust me. More than that, if there is any possible way of
+untangling this mystery, I shall do it."
+
+Mrs. Blake looked rather than spoke her thanks. As we went
+downstairs, accompanied by Miss Sears, we could see in the music
+room a very interesting couple, chatting earnestly over the piano.
+
+Betty Blake, a slip of a girl in her first season, was dividing
+her attention between her visitor and the door by which we were
+passing.
+
+She rose as she heard us, leaving the young man standing alone at
+the piano. He was of an age perhaps a year or two older than
+Reginald Blake. It was evident that, whatever Miss Betty might
+think, he had eyes for no one else but the pretty debutante. He
+even seemed to be regarding Kennedy sullenly, as if he were a
+possible rival.
+
+"You--you don't think it is serious?" whispered Betty in an
+undertone, scarcely waiting to be introduced. She had evidently
+known of our visit, but had been unable to get away to be present
+upstairs.
+
+"Really, Miss Blake," reassured Kennedy, "I can't say. All I can
+do is to repeat what I have already said to your mother. Keep up a
+good heart and trust me to work it out."
+
+"Thank you," she murmured, and then, impulsively extending her
+small hand to Craig, she added, "Mr. Kennedy, if there is anything
+I can do to help you, I beg that you will call on me."
+
+"I shall not forget," he answered, relinquishing the hand
+reluctantly. Then, as she thanked him, and turned again to her
+guest, he added in a low tone to me, "A remarkable girl, Walter, a
+girl that can be depended on."
+
+We followed Miss Sears down the hall.
+
+"Who was that young man in the music room?" asked Kennedy, when we
+were out of earshot.
+
+"Duncan Baldwin," she answered. "A friend and bosom companion of
+Reginald."
+
+"He seems to think more of Betty than of her brother," Craig
+remarked dryly.
+
+Miss Sears smiled. "Sometimes, we think they are secretly
+engaged," she returned. We had almost reached the door. "By the
+way," she asked anxiously, "do you think there are any precautions
+that I should take for Mrs. Blake--and the rest?"
+
+"Hardly," answered Kennedy, after a moment's consideration, "as
+long as you have taken none in particular already. Still, I
+suppose it will do no harm to be as antiseptic as possible."
+
+"I shall try," she promised, her face showing that she considered
+the affair now in a much more serious light than she had before
+our visit.
+
+"And keep me informed of anything that turns up," added Kennedy
+handing her a card with the telephone number of the laboratory.
+
+As we left the Blake mansion, Kennedy remarked, "We must trace
+that car somehow--at least we must get someone working on that."
+
+Half an hour later we were in a towering office building on
+Liberty Street, the home of various kinds of insurance. Kennedy
+stopped before a door which bore the name, "Douglas Garwood:
+Insurance Adjuster."
+
+Briefly, Craig told the story of the stolen car, omitting the
+account of the dastardly method taken to blackmail Mrs. Blake. As
+he proceeded a light seemed to break on the face of Garwood, a
+heavyset man, whose very gaze was inquisitorial.
+
+"Yes, the theft has been reported to us already by Dr. Wilson
+herself," he interrupted. "The car was insured in a company I
+represent."
+
+"I had hoped so," remarked Kennedy, "Do you know the woman?" he
+added, watching the insurance adjuster who had been listening
+intently as he told about the fair motor car thief.
+
+"Know her?" repeated Garwood emphatically. "Why, man, we have been
+so close to that woman that I feel almost intimate with her. The
+descriptions are those of a lady, well-dressed, and with a voice
+and manner that would carry her through any of the fashionable
+hotels, perhaps into society itself."
+
+"One of a gang of blackmailers, then," I hazarded.
+
+Garwood shrugged his shoulders. "Perhaps," he acquiesced. "It is
+automobile thieving that interests me, though. Why," he went on,
+rising excitedly, "the gangs of these thieves are getting away
+with half a million dollars' worth of high-priced cars every year.
+The police seem to be powerless to stop it. We appeal to them, but
+with no result. So, now we have taken things into our own hands."
+
+"What are you doing in this case?" asked Kennedy.
+
+"What the insurance companies have to do to recover stolen
+automobiles," Garwood replied. "For, with all deference to your
+friend, Deputy O'Connor, it is the insurance companies rather than
+the police who get stolen cars back."
+
+He had pulled out a postal card from a pigeon hole in his desk,
+selecting it from several apparently similar. We read:
+
+$250.00 REWARD
+
+We will pay $100.00 for car, $150.00 additional for information
+which will convict the thief. When last seen, driven by a woman,
+name not known, who is described as dark-haired, well-dressed,
+slight, apparently thirty years old. The car is a Dixon, 1912,
+seven-passenger, touring, No. 193,222, license No. 200,859, New
+York; dark red body, mohair top, brass lamps, has no wind shield;
+rear axle brake band device has extra nut on turnbuckle not
+painted. Car last seen near Prince Henry Hotel, New York City,
+Friday, the 10th.
+
+Communicate by telegraph or telephone, after notifying nearest
+police department, with Douglas Garwood, New York City. "The
+secret of it is," explained Garwood, as we finished reading, "that
+there are innumerable people who keep their eyes open and like to
+earn money easily. Thus we have several hundreds of amateur and
+enthusiastic detectives watching all over the city and country for
+any car that looks suspicious."
+
+Kennedy thanked him for his courtesy, and we rose to go. "I shall
+be glad to keep you informed of anything that turns up," he
+promised.
+
+
+
+
+CHAPTER XX
+
+THE ARTIFICIAL KIDNEY
+
+
+In the laboratory, Kennedy quietly set to work. He began by
+tearing from the germ letter the piece of gelatine and first
+examining it with a pocket lens. Then, with a sterile platinum
+wire, he picked out several minute sections of the black spot on
+the gelatine and placed them in agar, blood serum, and other media
+on which they would be likely to grow.
+
+"I shall have to wait until to-morrow to examine them properly,"
+he remarked. "There are colonies of something there, all right,
+but I must have them more fully developed."
+
+A hurried telephone call late in the day from Miss Sears told us
+that Mrs. Blake herself had begun to complain, and that Dr. Wilson
+had been summoned but had been unable to give an opinion on the
+nature of the malady.
+
+Kennedy quickly decided on making a visit to the doctor, who lived
+not far downtown from the laboratory.
+
+Dr. Rae Wilson proved to be a nervous little woman, inclined, I
+felt, to be dictatorial. I thought that secretly she felt a little
+piqued at our having been taken into the Blakes' confidence before
+herself, and Kennedy made every effort to smooth that aspect over
+tactfully.
+
+"Have you any idea what it can be?" he asked finally.
+
+She shook her head noncommittally. "I have taken blood smears," she
+answered, "but so far haven't been able to discover anything. I
+shall have to have her under observation for a day or two before I
+can answer that. Still, as Mrs. Blake is so ill, I have ordered
+another trained nurse to relieve Miss Sears of the added work, a
+very efficient nurse, a Miss Rogers."
+
+Kennedy had risen to go. "You have had no word about your car?" he
+asked casually.
+
+"None yet. I'm not worrying. It was insured."
+
+"Who is this arch criminal, Dr. Hopf?" I mused as we retraced our
+steps to the laboratory. "Is Mrs. Blake stricken now by the same
+trouble that seems to have affected Buster?"
+
+"Only my examination will show," he said. "I shall let nothing
+interfere with that now. It must be the starting point for any
+work that I may do in the case."
+
+We arrived at Kennedy's workshop of scientific crime and he
+immediately plunged into work. Looking up he caught sight of me
+standing helplessly idle.
+
+"Walter," he remarked thoughtfully adjusting a microscope,
+"suppose you run down and see Garwood. Perhaps he has something to
+report. And by the way, while you are out, make inquiries about
+the Blakes, young Baldwin, Miss Sears and this Dr. Wilson. I have
+heard of her before, at least by name. Perhaps you may find
+something interesting."
+
+Glad to have a chance to seem to be doing something whether it
+amounted to anything or not, I dropped in to see Garwood. So far
+he had nothing to report except the usual number of false alarms.
+From his office I went up to the Star where fortunately I found
+one of the reporters who wrote society notes.
+
+The Blakes, I found, as we already knew, to be well known and
+moving in the highest social circles. As far as known they had no
+particular enemies, other than those common to all people of great
+wealth. Dr. Wilson had a large practice, built up in recent years,
+and was one of the best known society physicians for women. Miss
+Sears was unknown, as far as I could determine. As for Duncan
+Baldwin, I found that he had become acquainted with Reginald Blake
+in college, that he came of no particular family and seemed to
+have no great means, although he was very popular in the best
+circles. In fact he had had, thanks to his friend, a rather
+meteoric rise in society, though it was reported that he was
+somewhat involved in debt as a result.
+
+I returned to the laboratory to find that Craig had taken out of a
+cabinet a peculiar looking arrangement. It consisted of thirty-two
+tubes, each about sixteen inches long, with S-turns, like a minute
+radiator. It was altogether not over a cubic foot in size, and
+enclosed in a glass cylinder. There were in it, perhaps, fifty
+feet of tubes, a perfectly-closed tubular system which I noticed
+Kennedy was keeping absolutely sterile in a germicidal solution of
+some kind.
+
+Inside the tubes and surrounding them was a saline solution which
+was kept at a uniform temperature by a special heating apparatus.
+
+Kennedy had placed the apparatus on the laboratory table and then
+gently took the little dog from his basket and laid him beside it.
+A few minutes later the poor little suffering Buster was
+mercifully under the influence of an anesthetic.
+
+Quickly Craig worked. First he attached the end of one of the
+tubes by means of a little cannula to the carotid artery of the
+dog. Then the other was attached to the jugular vein.
+
+As he released the clamp which held the artery, the little dog's
+feverishly beating heart spurted the arterial blood from the
+carotid into the tubes holding the normal salt solution and that
+pressure, in turn, pumped the salt solution which filled the tubes
+into the jugular vein, thus replacing the arterial blood that had
+poured into the tubes from the other end and maintaining the
+normal hydrostatic conditions in the body circulation. The dog was
+being kept alive, although perhaps a third of his blood was out of
+his body.
+
+"You see," he said at length, after we had watched the process a
+few minutes, "what I have here is in reality an artificial kidney.
+It is a system that has been devised by several doctors at Johns
+Hopkins.
+
+"If there is any toxin in the blood of this dog, the kidneys are
+naturally endeavoring to eliminate it. Perhaps it is being
+eliminated too slowly. In that case this arrangement which I have
+here will aid them. We call it vividiffusion and it depends for
+its action on the physical principle of osmosis, the passage of
+substances of a certain kind through a porous membrane, such as
+these tubes of celloidin.
+
+"Thus any substance, any poison that is dialyzable is diffused
+into the surrounding salt solution and the blood is passed back
+into the body, with no air in it, no infection, and without
+alteration. Clotting is prevented by the injection of a harmless
+substance derived from leeches, known as hirudin. I prevent the
+loss of anything in the blood which I want retained by placing in
+the salt solution around the tubes an amount of that substance
+equal to that held in solution by the blood. Of course that does
+not apply to the colloidal substances in the blood which would not
+pass by osmosis under any circumstances. But by such adjustments I
+can remove and study any desired substance in the blood, provided
+it is capable of diffusion. In fact this little apparatus has been
+found in practice to compare favorably with the kidneys themselves
+in removing even a lethal dose of poison."
+
+I watched in amazement. He was actually cleaning the blood of the
+dog and putting it back again, purified, into the little body. Far
+from being cruel, as perhaps it might seem, it was in reality
+probably the only method by which the animal could be saved, and
+at the same time it was giving us a clue as to some elusive,
+subtle substance used in the case.
+
+"Indeed," Kennedy went on reflectively, "this process can be kept
+up for several hours without injury to the dog, though I do not
+think that will be necessary to relieve the unwonted strain that
+has been put upon his natural organs. Finally, at the close of the
+operation, serious loss of blood is overcome by driving back the
+greater part of it into his body, closing up the artery and vein,
+and taking good care of the animal so that he will make a quick
+recovery."
+
+For a long time I watched the fascinating process of seeing the
+life blood coursing through the porous tubes in the salt solution,
+while Kennedy gave his undivided attention to the success of the
+delicate experiment. It was late when I left him, still at work
+over Buster, and went up to our apartment to turn in, convinced
+that nothing more would happen that night.
+
+The next morning, with characteristic energy, Craig was at work
+early, examining the cultures he had made from the black spots on
+the gelatine.
+
+By the look of perplexity on his face, I knew that he had
+discovered something that instead of clearing the mystery up,
+further deepened it.
+
+"What do you find?" I asked anxiously.
+
+"Walter," he exclaimed, laying aside the last of the slides which
+he had been staining and looking at intently through the
+microscope, "that stuff on the gelatine is entirely harmless.
+There was nothing in it except common mold."
+
+For the moment I did not comprehend. "Mold?" I repeated.
+
+"Yes," he replied, "just common, ordinary mold such as grows on
+the top of a jar of fruit or preserves when it is exposed to the
+air."
+
+I stifled an exclamation of incredulity. It seemed impossible that
+the deadly germ note should be harmless, in view of the events
+that had followed its receipt.
+
+Just then the laboratory door was flung open and Reginald Blake,
+pale and excited, entered. He had every mark of having been up all
+night.
+
+"What's the matter?" asked Craig.
+
+"It's about my mother," he blurted out. "She seems to be getting
+worse all the time. Miss Sears is alarmed, and Betty is almost ill
+herself with worry. Dr. Wilson doesn't seem to know what it is
+that affects her, and neither does the new nurse. Can you DO
+something?"
+
+There was a tone of appeal in his voice that was not like the
+self-sufficient Reginald of the day before.
+
+"Does there seem to be any immediate danger?" asked Kennedy.
+
+"Perhaps not--I can't say," he urged. "But she is gradually
+getting worse instead of better."
+
+Kennedy thought a moment. "Has anything else happened?" he asked
+slowly.
+
+"N-no. That's enough, isn't it?"
+
+"Indeed it is," replied Craig, trying to be reassuring. Then,
+recollecting Betty, he added, "Reginald, go back and tell your
+sister for me that she must positively make the greatest effort of
+her life to control herself. Tell her that her mother needs her--
+needs her well and brave. I shall be up at the house immediately.
+Do the best you can. I depend on you."
+
+Kennedy's words seemed to have a bracing effect on Reginald and a
+few moments later he left, much calmer.
+
+"I hope I have given him something to do which will keep him from
+mussing things up again," remarked Kennedy, mindful of Reginald's
+former excursion into detective work.
+
+Meanwhile Craig plunged furiously into his study of the substances
+he had isolated from the saline solution in which he had "washed"
+the blood of the little Pekinese.
+
+"There's no use doing anything in the dark," he explained. "Until
+we know what it is we are fighting we can't very well fight."
+
+For the moment I was overwhelmed by the impending tragedy that
+seemed to be hanging over Mrs. Blake. The more I thought of it,
+the more inexplicable became the discovery of the mold.
+
+"That is all very well about the mold on the gelatine strip in the
+letter," I insisted at length. "But, Craig, there must be
+something wrong somewhere. Mere molds could not have made Buster
+so ill, and now the infection, or whatever it is, has spread to
+Mrs. Blake herself. What have you found out by studying Buster?"
+
+He looked up from his close scrutiny of the material in one of the
+test tubes which contained something he had recovered from the
+saline solution of the diffusion apparatus.
+
+I could read on his face that whatever it was, it was serious.
+"What is it?" I repeated almost breathlessly.
+
+"I suppose I might coin a word to describe it," he answered
+slowly, measuring his phrases. "Perhaps it might be called
+hyper-amino-acidemia."
+
+I puckered my eyes at the mouth-filling term Kennedy smiled. "It
+would mean," he explained, "a great quantity of the amino-acids,
+non-coagulable, nitrogenous compounds in the blood. You know the
+indols, the phenols, and the amins are produced both by
+putrefactive bacteria and by the process of metabolism, the
+burning up of the tissues in the process of utilizing the energy
+that means life. But under normal circumstances, the amins are not
+present in the blood in any such quantities as I have discovered
+by this new method of diffusion."
+
+He paused a moment, as if in deference to my inability to follow
+him on such an abstruse topic, then resumed, "As far as I am able
+to determine, this poison or toxin is an amin similar to that
+secreted by certain cephalopods found in the neighborhood of
+Naples. It is an aromatic amin. Smell it."
+
+I bent over and inhaled the peculiar odor.
+
+"Those creatures," he continued, "catch their prey by this highly
+active poison secreted by the so-called salivary glands. Even a
+little bit will kill a crab easily."
+
+I was following him now with intense interest, thinking of the
+astuteness of a mind capable of thinking of such a poison.
+
+"Indeed, it is surprising," he resumed thoughtfully, "how many an
+innocent substance can be changed by bacteria into a virulent
+poison. In fact our poisons and our drugs are in many instances
+the close relations of harmless compounds that represent the
+intermediate steps in the daily process of metabolism."
+
+"Then," I put in, "the toxin was produced by germs, after all?"
+
+"I did not say that," he corrected. "It might have been. But I
+find no germs in the blood of Buster. Nor did Dr. Wilson find any
+in the blood smears which she took from Mrs. Blake."
+
+He seemed to have thrown the whole thing back again into the limbo
+of the unexplainable, and I felt nonplussed.
+
+"The writer of that letter," he went on, waving the piece of
+sterile platinum wire with which he had been transferring drops of
+liquid in his search for germs, "was a much more skillful
+bacteriologist than I thought, evidently. No, the trouble does not
+seem to be from germs breathed in, or from germs at all--it is
+from some kind of germ-free toxin that has been injected or
+otherwise introduced."
+
+Vaguely now I began to appreciate the terrible significance of
+what he had discovered.
+
+"But the letter?" I persisted mechanically.
+
+"The writer of that was quite as shrewd a psychologist as
+bacteriologist," pursued Craig impressively. "He calculated the
+moral effect of the letter, then of Buster's illness, and finally
+of reaching Mrs. Blake herself."
+
+"You think Dr. Rae Wilson knows nothing of it yet?" I queried.
+
+Kennedy appeared to consider his answer carefully. Then he said
+slowly: "Almost any doctor with a microscope and the faintest
+trace of a scientific education could recognize disease germs
+either naturally or feloniously implanted. But when it comes to
+the detection of concentrated, filtered, germ-free toxins, almost
+any scientist might be baffled. Walter," he concluded, "this is
+not mere blackmail, although perhaps the visit of that woman to
+the Prince Henry--a desperate thing in itself, although she did
+get away by her quick thinking--perhaps that shows that these
+people are ready to stop at nothing. No, it goes deeper than
+blackmail."
+
+I stood aghast at the discovery of this new method of scientific
+murder. The astute criminal, whoever he might be, had planned to
+leave not even the slender clue that might be afforded by disease
+germs. He was operating, not with disease itself, but with
+something showing the ultimate effects, perhaps, of disease with
+none of the preliminary symptoms, baffling even to the best of
+physicians.
+
+I scarcely knew what to say. Before I realized it, however, Craig
+was at last ready for the promised visit to Mrs. Blake. We went
+together, carrying Buster, in his basket, not recovered, to be
+sure, but a very different little animal from the dying creature
+that had been sent to us at the laboratory.
+
+
+
+
+CHAPTER XXI
+
+THE POISON BRACELET
+
+
+We reached the Blake mansion and were promptly admitted. Miss
+Betty, bearing up bravely under Reginald's reassurances, greeted
+us before we were fairly inside the door, though she and her
+brother were not able to conceal the fact that their mother was no
+better. Miss Sears was out, for an airing, and the new nurse, Miss
+Rogers, was in charge of the patient.
+
+"How do you feel, this morning?" inquired Kennedy as we entered
+the sun-parlor, where Mrs. Blake had first received us.
+
+A single glance was enough to satisfy me of the seriousness of her
+condition. She seemed to be in almost a stupor from which she
+roused herself only with difficulty. It was as if some
+overpowering toxin were gradually undermining her already weakened
+constitution.
+
+She nodded recognition, but nothing further.
+
+Kennedy had set the dog basket down near her wheel-chair and she
+caught sight of it.
+
+"Buster?" she murmured, raising her eyes. "Is--he--all right?"
+
+For answer, Craig simply raised the lid of the basket. Buster
+already seemed to have recognized the voice of his mistress, and,
+with an almost human instinct, to realize that though he himself
+was still weak and ill, she needed encouragement.
+
+As Mrs. Blake stretched out her slender hand, drawn with pain, to
+his silky head, he gave a little yelp of delight and his little
+red tongue eagerly caressed her hand.
+
+It was as though the two understood each other. Although Mrs.
+Blake, as yet, had no more idea what had happened to her pet, she
+seemed to feel by some subtle means of thought transference that
+the intelligent little animal was conveying to her a message of
+hope. The caress, the sharp, joyous yelp, and the happy wagging of
+the bushy tail seemed to brighten her up, at least for the moment,
+almost as if she had received a new impetus.
+
+"Buster!" she exclaimed, overjoyed to get her pet back again in so
+much improved condition.
+
+"I wouldn't exert myself too much, Mrs. Blake," cautioned Kennedy.
+
+"Were--were there any germs in the letter?" she asked, as Reginald
+and Betty stood on the other side of the chair, much encouraged,
+apparently, at this show of throwing off the lethargy that had
+seized her.
+
+"Yes, but about as harmless as those would be on a piece of
+cheese," Kennedy hastened. "But I--I feel so weak, so played out--
+and my head--"
+
+Her voice trailed off, a too evident reminder that her improvement
+had been only momentary and prompted by the excitement of our
+arrival.
+
+Betty bent down solicitously and made her more comfortable as only
+one woman can make another. Kennedy, meanwhile, had been talking
+to Miss Rogers, and I could see that he was secretly taking her
+measure.
+
+"Has Dr. Wilson been here this morning?" I heard him ask.
+
+"Not yet," she replied. "But we expect her soon."
+
+"Professor Kennedy?" announced a servant.
+
+"Yes?" answered Craig.
+
+"There is someone on the telephone who wants to speak to you. He
+said he had called the laboratory first and that they told him to
+call you here."
+
+Kennedy hurried after the servant, while Betty and Reginald joined
+me, waiting, for we seemed to feel that something was about to
+happen.
+
+"One of the unofficial detectives has unearthed a clue," he
+whispered to me a few moments later when he returned. "It was
+Garwood." Then to the others he added, "A car, repainted, and with
+the number changed, but otherwise answering the description of Dr.
+Wilson's has been traced to the West Side. It is somewhere in the
+neighborhood of a saloon and garage where drivers of taxicabs hang
+out. Reginald, I wish you would come along with us."
+
+To Betty's unspoken question Craig hastened to add, "I don't think
+there is any immediate danger. If there is any change--let me
+know. I shall call up soon. And meanwhile," he lowered his voice
+to impress the instruction on her, "don't leave your mother for a
+moment--not for a moment," he emphasized.
+
+Reginald was ready and together we three set off to meet Garwood
+at a subway station near the point where the car had been
+reported. We had scarcely closed the front door, when we ran into
+Duncan Baldwin, coming down the street, evidently bent on
+inquiring how Mrs. Blake and Betty were.
+
+"Much better," reassured Kennedy. "Come on, Baldwin. We can't have
+too many on whom we can rely on an expedition like this."
+
+"Like what?" he asked, evidently not comprehending.
+
+"There's a clue, they think, to that car of Dr. Wilson's," hastily
+explained Reginald, linking his arm into that of his friend and
+falling in behind us, as Craig hurried ahead.
+
+It did not take long to reach the subway, and as we waited for the
+train, Craig remarked: "This is a pretty good example of how the
+automobile is becoming one of the most dangerous of criminal
+weapons. All one has to do nowadays, apparently, after committing
+a crime, is to jump into a waiting car and breeze away, safe."
+
+We met Garwood and under his guidance picked our way westward from
+the better known streets in the heart of the city, to a section
+that was anything but prepossessing.
+
+The place which Garwood sought was a typical Raines Law hotel on a
+corner, with a saloon on the first floor, and apparently the
+requisite number of rooms above to give it a legal license.
+
+We had separated a little so that we would not attract undue
+attention. Kennedy and I entered the swinging doors boldly, while
+the others continued across to the other corner to wait with
+Garwood and take in the situation. It was a strange expedition and
+Reginald was fidgeting while Duncan seemed nervous.
+
+Among the group of chauffeurs lounging at the bar and in the back
+room anyone who had ever had any dealings with the gangs of New
+York might have recognized the faces of men whose pictures were in
+the rogues' gallery and who were members of those various
+aristocratic organizations of the underworld.
+
+Kennedy glanced about at the motley crowd. "This is a place where
+you need only to be introduced properly," he whispered to me, "to
+have any kind of crime committed for you."
+
+As we stood there, observing, without appearing to do so, through
+an open window on the side street I could tell from the sounds
+that there was a garage in the rear of the hotel.
+
+We were startled to hear a sudden uproar from the street.
+
+Garwood, impatient at our delay, had walked down past the garage
+to reconnoiter. A car was being backed out hurriedly, and as it
+turned and swung around the corner, his trained eye had recognized
+it.
+
+Instantly he had reasoned that it was an attempt to make a
+getaway, and had raised an alarm.
+
+Those nearest the door piled out, keen for any excitement. We,
+too, dashed out on the street. There we saw passing an automobile,
+swaying and lurching at the terrific speed with which its driver,
+urged it up the avenue. As he flashed by he looked like an Italian
+to me, perhaps a gunman.
+
+Garwood had impressed a passing trolley car into service and was
+pursuing the automobile in it, as it swayed on its tracks as
+crazily as the motor did on the roadway, running with all the
+power the motorman could apply.
+
+A mounted policeman galloped past us, blazing away at the tires.
+The avenue was stirred, as seldom even in its strenuous life, with
+reports of shots, honking of horns, the clang of trolley bells and
+the shouts of men.
+
+The pursuers were losing when there came a rattle and roar from
+the rear wheels which told that the tires were punctured and the
+heavy car was riding on its rims. A huge brewery wagon crossing a
+side street paused to see the fun, effectually blocking the road.
+
+The car jolted to a stop. The chauffeur leaped out and a moment
+later dived down into a cellar. In that congested district,
+pursuit was useless.
+
+"Only an accomplice," commented Kennedy. "Perhaps we can get him
+some other way if we can catch the man--or woman--higher up."
+
+Down the street now we could see Garwood surrounded by a curious
+crowd but in possession of the car. I looked about for Duncan and
+Reginald. They had apparently been swallowed up in the crowds of
+idlers which seemed to be pouring out of nowhere, collecting to
+gape at the excitement, after the manner of a New York crowd.
+
+As I ran my eye over them, I caught sight of Reginald near the
+corner where we had left him in an incipient fight with someone
+who had a fancied grievance. A moment later we had rescued him.
+
+"Where's Duncan?" he panted. "Did anything happen to him? Garwood
+told us to stay here--but we got separated."
+
+Policemen had appeared on the heels of the crowd and now, except
+for a knot following Garwood, things seemed to be calming down.
+
+The excitement over, and the people thinning out, Kennedy still
+could not find any trace of Duncan. Finally he glanced in again
+through the swinging doors. There was Duncan, evidently quite
+upset by what had occurred, fortifying himself at the bar.
+
+Suddenly from above came a heavy thud, as if someone had fallen on
+the floor above us, followed by a suppressed shuffling of feet and
+a cry of help.
+
+Kennedy sprang toward a side door which led out into the hall to
+the hotel room above. It was locked. Before any of the others he
+ran out on the street and into the hall that way, taking the
+stairs two at a time, past a little cubby-hole of an "office" and
+down the upper hall to a door from which came the cry.
+
+It was a peculiar room into which we burst, half bedroom, half
+workshop, or rather laboratory, for on a deal table by a window
+stood a rack of test-tubes, several beakers, and other
+paraphernalia.
+
+A chambermaid was shrieking over a woman who was lying lethargic
+on the floor.
+
+I looked more closely.
+
+It was Dora Sears.
+
+For the moment I could not imagine what had happened. Had the
+events of the past few days worked on her mind and driven her into
+temporary insanity? Or had the blackmailing gang of automobile
+thieves, failing in extorting money by their original plan, seized
+her?
+
+Kennedy bent over and tried to lift her up. As he did so, the gold
+bracelet, unclasped, clattered to the floor.
+
+He picked it up and for a moment looked at it. It was hollow, but
+in that part of it where it unclasped could be seen a minute
+hypodermic needle and traces of a liquid.
+
+"A poison bracelet," he muttered to himself, "one in which enough
+of a virulent poison could be hidden so that in an emergency death
+could cheat the law."
+
+"But this Dr. Hopf," exclaimed Reginald, who stood behind us
+looking from the insensible girl to the bracelet and slowly
+comprehending what it all meant, "she alone knows where and who he
+is!"
+
+We looked at Kennedy. What was to be done? Was the criminal higher
+up to escape because one of his tools had been cornered and had
+taken the easiest way to get out?
+
+Kennedy had taken down the receiver of the wall telephone in the
+room. A moment later he was calling insistently for his
+laboratory. One of the students in another part of the building
+answered. Quickly he described the apparatus for vividiffusion and
+how to handle it without rupturing any of the delicate tubes.
+
+"The large one," he ordered, "with one hundred and ninety-two
+tubes. And hurry."
+
+Before the student appeared, came an ambulance which some one in
+the excitement had summoned. Kennedy quickly commandeered both the
+young doctor and what surgical material he had with him.
+
+Briefly he explained what he proposed to do and before the student
+arrived with the apparatus, they had placed the nurse in such a
+position that they were ready for the operation.
+
+The next room which was unoccupied had been thrown open to us and
+there I waited with Reginald and Duncan, endeavoring to explain to
+them the mysteries of the new process of washing the blood.
+
+The minutes lengthened into hours, as the blood of the poisoned
+girl coursed through its artificial channel, literally being
+washed of the toxin from the poisoned bracelet.
+
+Would it succeed? It had saved the life of Buster. But would it
+bring back the unfortunate before us, long enough even for her to
+yield her secret and enable us to catch the real criminal. What if
+she died?
+
+As Kennedy worked, the young men with me became more and more
+fascinated, watching him. The vividiffusion apparatus was now in
+full operation.
+
+In the intervals when he left the apparatus in charge of the young
+ambulance surgeon Kennedy was looking over the room. In a trunk
+which was open he found several bundles of papers. As he ran his
+eye over them quickly, he selected some and stuffed them into his
+pocket, then went back to watch the working of the apparatus.
+
+Reginald, who had been growing more and more nervous, at last
+asked if he might call up Betty to find out how his mother was.
+
+He came back from the telephone, his face wrinkled.
+
+"Poor mother," he remarked anxiously, "do you think she will pull
+through, Professor? Betty says that Dr. Wilson has given her no
+idea yet about the nature of the trouble."
+
+Kennedy thought a moment. "Of course," he said, "your mother has
+had no such relative amount of the poison as Buster has had. I
+think that undoubtedly she will recover by purely natural means. I
+hope so. But if not, here is the apparatus," and he patted the
+vividiffusion tubes in their glass case, "that will save her,
+too."
+
+As well as I could I explained to Reginald the nature of the toxin
+that Kennedy had discovered. Duncan listened, putting in a
+question now and then. But it was evident that his thoughts were
+on something else, and now and then Reginald, breaking into his
+old humor, rallied him about thinking of Betty.
+
+A low exclamation from both Kennedy and the surgeon attracted us.
+
+Dora Sears had moved.
+
+The operation of the apparatus was stopped, the artery and vein
+had been joined up, and she was slowly coming out from under the
+effects of the anesthetic.
+
+As we gathered about her, at a little distance, we heard her cry
+in her delirium, "I--I would have--done--anything--for him."
+
+We strained our ears. Was she talking of the blackmailer, Dr.
+Hopf?
+
+"Who?" asked Craig, bending over close to her ear.
+
+"I--I would--have done anything," she repeated as if someone had
+contradicted her. She went on, dreamily, ramblingly, "He--is--is--
+my brother. I--"
+
+She stopped through weakness.
+
+"Where is Dr. Hopf?" asked Kennedy, trying to recall her fleeting
+attention.
+
+"Dr. Hopf? Dr. Hopf?" she repeated, then smiling to herself as
+people will when they are leaving the borderline of anesthesia,
+she repeated the name, "Hopf?"
+
+"Yes," persisted Kennedy.
+
+"There is no Dr. Hopf," she added. "Tell me--did--did they--"
+
+"No Dr. Hopf?" Kennedy insisted.
+
+She had lapsed again into half insensibility.
+
+He rose and faced us, speaking rapidly.
+
+"New York seems to have a mysterious and uncanny attraction for
+odds and ends of humanity, among them the great army of
+adventuresses. In fact there often seems to be something decidedly
+adventurous about the nursing profession. This is a girl of
+unusual education in medicine. Evidently she has traveled--her
+letters show it. Many of them show that she has been in Italy.
+Perhaps it was there that she heard of the drug that has been used
+in this case. It was she who injected the germ-free toxin, first
+into the dog, then into Mrs. Blake, she who wrote the blackmail
+letter which was to have explained the death."
+
+He paused. Evidently she had heard dimly, was straining every
+effort to hear. In her effort she caught sight of our faces.
+
+Suddenly, as if she had seen an apparition, she raised herself
+with almost superhuman strength.
+
+"Duncan!" she cried. "Duncan! Why--didn't you--get away--while
+there was time--after you warned me?"
+
+Kennedy had wheeled about and was facing us. He was holding in his
+hand some of the letters he had taken from the trunk. Among others
+was a folded piece of parchment that looked like a diploma. He
+unfolded it and we bent over to read.
+
+It was a diploma from the Central Western College of Nursing. As I
+read the name written in, it was with a shock. It was not Dora
+Sears, but Dora Baldwin.
+
+"A very clever plot," he ground out, taking a step nearer us.
+"With the aid of your sister and a disreputable gang of chauffeurs
+you planned to hasten the death of Mrs. Blake, to hasten the
+inheritance of the Blake fortune by your future wife. I think your
+creditors will have less chance of collecting now than ever,
+Duncan Baldwin."
+
+
+
+
+CHAPTER XXII
+
+THE DEVIL WORSHIPERS
+
+
+Tragic though the end of the young nurse, Dora Baldwin, had been,
+the scheme of her brother, in which she had become fatally
+involved, was by no means as diabolical as that in the case that
+confronted us a short time after that.
+
+I recall this case particularly not only because it was so weird
+but also because of the unique manner in which it began.
+
+"I am damned--Professor Kennedy--damned!"
+
+The words rang out as the cry of a lost soul. A terrible look of
+inexpressible anguish and fear was written on the face of Craig's
+visitor, as she uttered them and sank back, trembling, in the easy
+chair, mentally and physically convulsed.
+
+As nearly as I had been able to follow, Mrs. Veda Blair's story
+had dealt mostly with a Professor and Madame Rapport and something
+she called the "Red Lodge" of the "Temple of the Occult."
+
+She was not exactly a young woman, although she was a very
+attractive one. She was of an age that is, perhaps, even more
+interesting than youth.
+
+Veda Blair, I knew, had been, before her recent marriage to Seward
+Blair, a Treacy, of an old, though somewhat unfortunate, family.
+Both the Blairs and the Treacys had been intimate and old Seward
+Blair, when he died about a year before, had left his fortune to
+his son on the condition that he marry Veda Treacy.
+
+"Sometimes," faltered Mrs. Blair, "it is as though I had two
+souls. One of them is dispossessed of its body and the use of its
+organs and is frantic at the sight of the other that has crept
+in."
+
+She ended her rambling story, sobbing the terrible words, "Oh--I
+have committed the unpardonable sin--I am anathema--I am damned--
+damned!"
+
+She said nothing of what terrible thing she had done and Kennedy,
+for the present, did not try to lead the conversation. But of all
+the stories that I have heard poured forth in the confessional of
+the detective's office, hers, I think, was the wildest.
+
+Was she insane? At least I felt that she was sincere. Still, I
+wondered what sort of hallucination Craig had to deal with, as
+Veda Blair repeated the incoherent tale of her spiritual vagaries.
+
+Almost, I had begun to fancy that this was a case for a doctor,
+not for a detective, when suddenly she asked a most peculiar
+question.
+
+"Can people affect you for good or evil, merely by thinking about
+you?" she queried. Then a shudder passed over her. "They may be
+thinking about me now!" she murmured in terror.
+
+Her fear was so real and her physical distress so evident that
+Kennedy, who had been listening silently for the most part, rose
+and hastened to reassure her.
+
+"Not unless you make your own fears affect yourself and so play
+into their hands," he said earnestly.
+
+Veda looked at him a moment, then shook her head mournfully. "I
+have seen Dr. Vaughn," she said slowly.
+
+Dr. Gilbert Vaughn, I recollected, was a well-known alienist in
+the city.
+
+"He tried to tell me the same thing," she resumed doubtfully.
+"But--oh--I know what I know! I have felt the death thought--and
+he knows it!"
+
+"What do you mean?" inquired Kennedy, leaning forward keenly.
+
+"The death thought," she repeated, "a malicious psychic attack.
+Some one is driving me to death by it. I thought I could fight it
+off. I went away to escape it. Now I have come back--and I have
+not escaped. There is always that disturbing influence--always--
+directed against me. I know it will--kill me!"
+
+I listened, startled. The death thought! What did it mean? What
+terrible power was it? Was it hypnotism? What was this fearsome,
+cruel belief, this modern witchcraft that could unnerve a rich and
+educated woman? Surely, after all, I felt that this was not a case
+for a doctor alone; it called for a detective.
+
+"You see," she went on, heroically trying to control herself, "I
+have always been interested in the mysterious, the strange, the
+occult. In fact my father and my husband's father met through
+their common interest. So, you see, I come naturally by it.
+
+"Not long ago I heard of Professor and Madame Rapport and their
+new Temple of the Occult. I went to it, and later Seward became
+interested, too. We have been taken into a sort of inner circle,"
+she continued fearfully, as though there were some evil power in
+the very words themselves, "the Red Lodge."
+
+"You have told Dr. Vaughn?" shot out Kennedy suddenly, his eyes
+fixed on her face to see what it would betray.
+
+Veda leaned forward, as if to tell a secret, then whispered in a
+low voice, "He knows. Like us--he--he is a--Devil Worshiper!"
+
+"What?" exclaimed Kennedy in wide-eyed astonishment.
+
+"A Devil Worshiper," she repeated. "You haven't heard of the Red
+Lodge?"
+
+Kennedy nodded negatively. "Could you get us--initiated?" he
+hazarded.
+
+"P--perhaps," she hesitated, in a half-frightened tone. "I--I'll
+try to get you in to-night."
+
+She had risen, half dazed, as if her own temerity overwhelmed her.
+
+"You--poor girl," blurted out Kennedy, his sympathies getting the
+upper hand for the moment as he took the hand she extended mutely.
+"Trust me. I will do all in my power, all in the power of modern
+science to help you fight off this--influence."
+
+There must have been something magnetic, hypnotic in his eye.
+
+"I will stop here for you," she murmured, as she almost fled from
+the room.
+
+Personally, I cannot say that I liked the idea of spying. It is
+not usually clean and wholesome. But I realized that occasionally
+it was necessary.
+
+"We are in for it now," remarked Kennedy half humorously, half
+seriously, "to see the Devil in the twentieth century."
+
+"And I," I added, "I am, I suppose, to be the reporter to Satan."
+
+We said nothing more about it, but I thought much about it, and
+the more I thought, the more incomprehensible the thing seemed. I
+had heard of Devil Worship, but had always associated it with far-
+off Indian and other heathen lands--in fact never among Caucasians
+in modern times, except possibly in Paris. Was there such a cult
+here in my own city? I felt skeptical.
+
+That night, however, promptly at the appointed time, a cab called
+for us, and in it was Veda Blair, nervous but determined.
+
+"Seward has gone ahead," she explained. "I told him that a friend
+had introduced you, that you had studied the occult abroad. I
+trust you to carry it out."
+
+Kennedy reassured her.
+
+The curtains were drawn and we could see nothing outside, though
+we must have been driven several miles, far out into the suburbs.
+
+At last the cab stopped. As we left it we could see nothing of the
+building, for the cab had entered a closed courtyard.
+
+"Who enters the Red Lodge?" challenged a sepulchral voice at the
+porte-cochere. "Give the password!"
+
+"The Serpent's Tooth," Veda answered.
+
+"Who are these?" asked the voice.
+
+"Neophytes," she replied, and a whispered parley followed.
+
+"Then enter!" announced the voice at length.
+
+It was a large room into which we were first ushered, to be
+inducted into the rites of Satan.
+
+There seemed to be both men and women, perhaps half a dozen
+votaries. Seward Blair was already present. As I met him, I did
+not like the look in his eye; it was too stary. Dr. Vaughn was
+there, too, talking in a low tone to Madame Rapport. He shot a
+quick look at us. His were not eyes but gimlets that tried to bore
+into your very soul. Chatting with Seward Blair was a Mrs.
+Langhorne, a very beautiful woman. To-night she seemed to be
+unnaturally excited.
+
+All seemed to be on most intimate terms, and, as we waited a few
+minutes, I could not help recalling a sentence from Huysmans: "The
+worship of the Devil is no more insane than the worship of God.
+The worshipers of Satan are mystics--mystics of an unclean sort,
+it is true, but mystics none the less."
+
+I did not agree with it, and did not repeat it, of course, but a
+moment later I overheard Dr. Vaughn saying to Kennedy: "Hoffman
+brought the Devil into modern life. Poe forgoes the aid of demons
+and works patiently and precisely by the scientific method. But
+the result is the same."
+
+"Yes," agreed Kennedy for the sake of appearances, "in a sense, I
+suppose, we are all devil worshipers in modern society--always
+have been. It is fear that rules and we fear the bad--not the
+good."
+
+As we waited, I felt, more and more, the sense of the mysterious,
+the secret, the unknown which have always exercised a powerful
+attraction on the human mind. Even the aeroplane and the
+submarine, the X-ray and wireless have not banished the occult.
+
+In it, I felt, there was fascination for the frivolous and deep
+appeal to the intellectual and spiritual. The Temple of the Occult
+had evidently been designed to appeal to both types. I wondered
+how, like Lucifer, it had fallen. The prime requisite, I could
+guess already, however, was--money. Was it in its worship of the
+root of all evil that it had fallen?
+
+We passed soon into another room, hung entirely in red, with
+weird, cabalistic signs all about, on the walls. It was uncanny,
+creepy.
+
+A huge reproduction in plaster of one of the most sardonic of
+Notre Dame's gargoyles seemed to preside over everything--a
+terrible figure in such an atmosphere.
+
+As we entered, we were struck by the blinding glare of the light,
+in contrast with the darkened room in which we had passed our
+brief novitiate, if it might be called such.
+
+Suddenly the lights were extinguished.
+
+The great gargoyle shone with an infernal light of its own!
+
+"Phosphorescent paint," whispered Kennedy to me.
+
+Still, it did not detract from the weird effect to know what
+caused it.
+
+There was a startling noise in the general hush.
+
+"Sata!" cried one of the devotees.
+
+A door opened and there appeared the veritable priest of the
+Devil--pale of face, nose sharp, mouth bitter, eyes glassy.
+
+"That is Rapport," Vaughn whispered to me.
+
+The worshipers crowded forward.
+
+Without a word, he raised his long, lean forefinger and began to
+single them out impressively. As he did so, each spoke, as if
+imploring aid.
+
+He came to Mrs. Langhorne.
+
+"I have tried the charm," she cried earnestly, "and the one whom I
+love still hates me, while the one I hate loves me!"
+
+"Concentrate!" replied the priest, "concentrate! Think always 'I
+love him. He must love me. I want him to love me. I love him. He
+must love me.' Over and over again you must think it. Then the
+other side, 'I hate him. He must leave me. I want him to leave me.
+I hate him--hate him.'"
+
+Around the circle he went.
+
+At last his lean finger was outstretched at Veda. It seemed as if
+some imp of the perverse were compelling her unwilling tongue to
+unlock its secrets.
+
+"Sometimes," she cried in a low, tremulous voice, "something seems
+to seize me, as if by the hand and urge me onward. I cannot flee
+from it."
+
+"Defend yourself!" answered the priest subtly. "When you know that
+some one is trying to kill you mentally, defend yourself! Work
+against it by every means in your power. Discourage! Intimidate!
+Destroy!"
+
+I marveled at these cryptic utterances. They shadowed a modern
+Black Art, of which I had had no conception--a recrudescence in
+other language of the age-old dualism of good and evil. It was a
+sort of mental malpractice.
+
+"Over and over again," he went on speaking to her, "the same
+thought is to be repeated against an enemy. 'You know you are
+going to die! You know you are going to die!' Do it an hour, two
+hours, at a time. Others can help you, all thinking in unison the
+same thought."
+
+What was this, I asked myself breathlessly--a new transcendental
+toxicology?
+
+Slowly, a strange mephitic vapor seemed to exhale into the room--
+or was it my heightened imagination?
+
+
+
+
+CHAPTER XXIII
+
+THE PSYCHIC CURSE
+
+
+There came a sudden noise--nameless--striking terror, low,
+rattling. I stood rooted to the spot. What was it that held me?
+Was it an atavistic joy in the horrible or was it merely a
+blasphemous curiosity?
+
+I scarcely dared to look.
+
+At last I raised my eyes. There was a live snake, upraised, his
+fangs striking out viciously--a rattler!
+
+I would have drawn back and fled, but Craig caught my arm.
+
+"Caged," he whispered monosyllabically.
+
+I shuddered. This, at least, was no drawing-room diablerie.
+
+"It is Ophis," intoned Rapport, "the Serpent--the one active form
+in Nature that cannot be ungraceful!"
+
+The appearance of the basilisk seemed to heighten the tension.
+
+At last it broke loose and then followed the most terrible
+blasphemies. The disciples, now all frenzied, surrounded closer
+the priest, the gargoyle and the serpent.
+
+They worshiped with howls and obscenities. Mad laughter mingled
+with pale fear and wild scorn in turns were written on the hectic
+faces about me.
+
+They had risen--it became a dance, a reel.
+
+The votaries seemed to spin about on their axes, as it were,
+uttering a low, moaning chant as they whirled. It was a mania, the
+spirit of demonism. Something unseen seemed to urge them on.
+
+Disgusted and stifled at the surcharged atmosphere, I would have
+tried to leave, but I seemed frozen to the spot. I could think of
+nothing except Poe's Masque of the Red Death.
+
+Above all the rest whirled Seward Blair himself. The laugh of the
+fiend, for the moment, was in his mouth. An instant he stood--the
+oracle of the Demon--devil-possessed. Around whirled the frantic
+devotees, howling.
+
+Shrilly he cried, "The Devil is in me!"
+
+Forward staggered the devil dancer--tall, haggard, with deep
+sunken eyes and matted hair, face now smeared with dirt and blood-
+red with the reflection of the strange, unearthly phosphorescence.
+
+He reeled slowly through the crowd, crooning a quatrain, in a low,
+monotonous voice, his eyelids drooping and his head forward on his
+breast:
+
+ If the Red Slayer think he slays,
+ Or the slain think he is slain,
+ They know not well the subtle ways
+ I keep and pass and turn again!
+
+Entranced the whirling crowd paused and watched. One of their
+number had received the "power."
+
+He was swaying slowly to and fro.
+
+"Look!" whispered Kennedy.
+
+His fingers twitched, his head wagged uncannily. Perspiration
+seemed to ooze from every pore. His breast heaved.
+
+He gave a sudden yell--ear-piercing. Then followed a screech of
+hellish laughter.
+
+The dance had ended, the dancers spellbound at the sight.
+
+He was whirling slowly, eyes protruding now, mouth foaming, chest
+rising and falling like a bellows, muscles quivering.
+
+Cries, vows, imprecations, prayers, all blended in an infernal
+hubbub.
+
+With a burst of ghastly, guttural laughter, he shrieked, "I AM the
+Devil!"
+
+His arms waved--cutting, sawing, hacking the air.
+
+The votaries, trembling, scarcely moved, breathed, as he danced.
+
+Suddenly he gave a great leap into the air--then fell, motionless.
+They crowded around him. The fiendish look was gone--the demoniac
+laughter stilled.
+
+It was over.
+
+The tension of the orgy had been too much for us. We parted, with
+scarcely a word, and yet I could feel that among the rest there
+was a sort of unholy companionship.
+
+Silently, Kennedy and I drove away in the darkened cab, this time
+with Seward and Veda Blair and Mrs. Langhorne.
+
+For several minutes not a word was said. I was, however, much
+occupied in watching the two women. It was not because of anything
+they said or did. That was not necessary. But I felt that there
+was a feud, something that set them against each other.
+
+"How would Rapport use the death thought, I wonder?" asked Craig
+speculatively, breaking the silence.
+
+Blair answered quickly. "Suppose some one tried to break away, to
+renounce the Lodge, expose its secrets. They would treat him so as
+to make him harmless--perhaps insane, confused, afraid to talk,
+paralyzed, or even to commit suicide or be killed in an accident.
+They would put the death thought on him!"
+
+Even in the prosaic jolting of the cab, away from the terrible
+mysteries of the Red Lodge, one could feel the spell.
+
+The cab stopped. Seward was on his feet in a moment and handing
+Mrs. Langhorne out at her home. For a moment they paused on the
+steps for an exchange of words.
+
+In that moment I caught flitting over the face of Veda a look of
+hatred, more intense, more real, more awful than any that had been
+induced under the mysteries of the rites at the Lodge.
+
+It was gone in an instant, and as Seward rejoined us I felt that,
+with Mrs. Langhorne gone, there was less restraint. I wondered
+whether it was she who had inspired the fear in Veda.
+
+Although it was more comfortable, the rest of our journey was made
+in silence and the Blairs dropped us at our apartment with many
+expressions of cordiality as we left them to proceed to their own.
+
+"Of one thing I'm sure," I remarked, entering the room where only
+a few short hours before Mrs. Blair had related her strange tale.
+"Whatever the cause of it, the devil dancers don't sham."
+
+Kennedy did not reply. He was apparently wrapped up in the
+consideration of the remarkable events of the evening.
+
+As for myself, it was a state of affairs which, the day before, I
+should have pronounced utterly beyond the wildest bounds of the
+imagination of the most colorful writer. Yet here it was; I had
+seen it.
+
+I glanced up to find Kennedy standing by the light examining
+something he had apparently picked up at the Red Lodge. I bent
+over to look at it, too. It was a little glass tube.
+
+"An ampoule, I believe the technical name of such a container is,"
+he remarked, holding it closer to the light.
+
+In it were the remains of a dried yellow substance, broken up
+minutely, resembling crystals.
+
+"Who dropped it?" I asked.
+
+"Vaughn, I think," he replied. "At least, I saw him near Blair,
+stooping over him, at the end, and I imagine this is what I saw
+gleaming for an instant in the light."
+
+Kennedy said nothing more, and for my part I was thoroughly at sea
+and could make nothing out of it all.
+
+"What object can such a man as Dr. Vaughn possibly have in
+frequenting such a place?" I asked at length, adding, "And there's
+that Mrs. Langhorne--she was interesting, too."
+
+Kennedy made no direct reply. "I shall have them shadowed to-
+morrow," he said briefly, "while I am at work in the laboratory
+over this ampoule."
+
+As usual, also, Craig had begun on his scientific studies long
+before I was able to shake myself loose from the nightmares that
+haunted me after our weird experience of the evening.
+
+He had already given the order to an agency for the shadowing, and
+his next move was to start me out, also, looking into the history
+of those concerned in the case. As far as I was able to determine,
+Dr. Vaughn had an excellent reputation, and I could find no reason
+whatever for his connection with anything of the nature of the Red
+Lodge. The Rapports seemed to be nearly unknown in New York,
+although it was reported that they had come from Paris lately.
+Mrs. Langhorne was a divorcee from one of the western states, but
+little was known about her, except that she always seemed to be
+well supplied with money. It seemed to be well known in the circle
+in which Seward Blair moved that he was friendly with her, and I
+had about reached the conclusion that she was unscrupulously
+making use of his friendship, perhaps was not above such a thing
+as blackmail.
+
+Thus the day passed, and we heard no word from Veda Blair,
+although that was explained by the shadows, whose trails crossed
+in a most unexpected manner. Their reports showed that there was a
+meeting at the Red Lodge during the late afternoon, at which all
+had been present except Dr. Vaughn. We learned also from them the
+exact location of the Lodge, in an old house just across the line
+in Westchester.
+
+It was evidently a long and troublesome analysis that Craig was
+engaged in at the laboratory, for it was some hours after dinner
+that night when he came into the apartment, and even then he said
+nothing, but buried himself in some of the technical works with
+which his library was stocked. He said little, but I gathered that
+he was in great doubt about something, perhaps, as much as
+anything, about how to proceed with so peculiar a case.
+
+It was growing late, and Kennedy was still steeped in his books,
+when the door of the apartment, which we happened to have left
+unlocked, was suddenly thrown open and Seward Blair burst in on
+us, wildly excited.
+
+"Veda is gone!" he cried, before either of us could ask him what
+was the matter.
+
+"Gone?" repeated Kennedy. "How--where?"
+
+"I don't know," Blair blurted out breathlessly. "We had been out
+together this afternoon, and I returned with her. Then I went out
+to the club after dinner for a while, and when I got back I missed
+her--not quarter of an hour ago. I burst into her room--and there
+I found this note. Read it. I don't know what to do. No one seems
+to know what has become of her. I've called up all over and then
+thought perhaps you might help me, might know some friend of hers
+that I don't know, with whom she might have gone out."
+
+Blair was plainly eager for us to help him. Kennedy took the paper
+from him. On it, in a trembling hand, were scrawled some words,
+evidently addressed to Blair himself:
+
+"You would forgive me and pity me if you knew what I have been
+through.
+
+"When I refused to yield my will to the will of the Lodge I
+suppose I aroused the enmity of the Lodge.
+
+"To-night as I lay in bed, alone, I felt that my hour had come,
+that mental forces that were almost irresistible were being
+directed against me.
+
+"I realized that I must fight not only for my sanity but for my
+life.
+
+"For hours I have fought that fight.
+
+"But during those hours, some one, I won't say who, seemed to have
+developed such psychic faculties of penetration that they were
+able to make their bodies pass through the walls of my room.
+
+"At last I am conquered. I pray that you--"
+
+The writing broke off abruptly, as if she had left it in wild
+flight.
+
+"What does that mean?" asked Kennedy, "the 'will of the Lodge'?"
+
+Blair looked at us keenly. I fancied that there was even something
+accusatory in the look. "Perhaps it was some mental reservation on
+her part," he suggested. "You do not know yourself of any reason
+why she should fear anything, do you?" he asked pointedly.
+
+Kennedy did not betray even by the motion of an eyelash that we
+knew more than we should ostensibly.
+
+There was a tap at the door. I sprang to open it, thinking
+perhaps, after all, it was Veda herself.
+
+Instead, a man, a stranger, stood there.
+
+"Is this Professor Kennedy?" he asked, touching his hat.
+
+Craig nodded.
+
+"I am from the psychopathic ward of the City Hospital--an orderly,
+sir," the man introduced.
+
+"Yes," encouraged Craig, "what can I do for you?"
+
+"A Mrs. Blair has just been brought in, sir, and we can't find her
+husband. She's calling for you now."
+
+Kennedy stared from the orderly to Seward Blair, startled,
+speechless.
+
+"What has happened?" asked Blair anxiously. "I am Mr. Blair."
+
+The orderly shook his head. He had delivered his message. That was
+all he knew.
+
+"What do you suppose it is?" I asked, as we sped across town in a
+taxicab. "Is it the curse that she dreaded?"
+
+Kennedy said nothing and Blair appeared to hear nothing. His face
+was drawn in tense lines.
+
+The psychopathic ward is at once one of the most interesting and
+one of the most depressing departments of a large city hospital,
+harboring, as it does, all from the more or less harmless insane
+to violent alcoholics and wrecked drug fiends.
+
+Mrs. Blair, we learned, had been found hatless, without money,
+dazed, having fallen, after an apparently aimless wandering in the
+streets.
+
+For the moment she lay exhausted on the white bed of the ward,
+eyes glazed, pupils contracted, pulse now quick, now almost
+evanescent, face drawn, breathing difficult, moaning now and then
+in physical and mental agony.
+
+Until she spoke it was impossible to tell what had happened, but
+the ambulance surgeon had found a little red mark on her white
+forearm and had pointed it out, evidently with the idea that she
+was suffering from a drug.
+
+At the mere sight of the mark, Blair stared as though hypnotized.
+Leaning over to Kennedy, so that the others could not hear, he
+whispered, "It is the mark of the serpent!"
+
+Our arrival had been announced to the hospital physician, who
+entered and stood for a moment looking at the patient.
+
+"I think it is a drug--a poison," he said meditatively.
+
+"You haven't found out yet what it is, then?" asked Craig.
+
+The physician shook his head doubtfully. "Whatever it is," he said
+slowly, "it is closely allied to the cyanide groups in its
+rapacious activity. I haven't the slightest idea of its true
+nature, but it seems to have a powerful affinity for important
+nerve centers of respiration and muscular coordination, as well as
+for disorganizing the blood. I should say that it produces death
+by respiratory paralysis and convulsions. To my mind it is an
+exact, though perhaps less active, counterpart of hydrocyanic
+acid."
+
+Kennedy had been listening intently at the start, but before the
+physician had finished he had bent over and made a ligature
+quickly with his handkerchief.
+
+Then he dispatched a messenger with a note. Next he cut about the
+minute wound on her arm until the blood flowed, cupping it to
+increase the flow. Now and then he had them administer a little
+stimulant.
+
+He had worked rapidly, while Blair watched him with a sort of
+fascination.
+
+"Get Dr. Vaughn," ordered Craig, as soon as he had a breathing
+spell after his quick work, adding, "and Professor and Madame
+Rapport. Walter, attend to that, will you? I think you will find
+an officer outside. You'll have to compel them to come, if they
+won't come otherwise," he added, giving the address of the Lodge,
+as we had found it.
+
+Blair shot a quick look at him, as though Craig in his knowledge
+were uncanny. Apparently, the address had been a secret which he
+thought we did not know.
+
+I managed to find an officer and dispatch him for the Rapports. A
+hospital orderly, I thought, would serve to get Dr. Vaughn.
+
+
+
+
+CHAPTER XXIV
+
+THE SERPENT'S TOOTH
+
+
+I had scarcely returned to the ward when, suddenly, an unnatural
+strength seemed to be infused into Veda.
+
+She had risen in bed.
+
+"It shall not catch me!" she cried in a new paroxysm of nameless
+terror. "No--no--it is pursuing me. I am never out of its grasp. I
+have been thought six feet underground--I know it. There it is
+again--still driving me--still driving me!
+
+"Will it never stop? Will no one stop it? Save me! It--is the
+death thought!"
+
+She had risen convulsively and had drawn back in abject, cowering
+terror. What was it she saw? Evidently it was very real and very
+awful. It pursued her relentlessly.
+
+As she lay there, rolling her eyes about, she caught sight of us
+and recognized us for the first time, although she had been
+calling for us.
+
+"They had the thought on you, too, Professor Kennedy," she almost
+screamed. "Hour after hour, Rapport and the rest repeated over and
+over again, 'Why does not some one kill him? Why does he not die?'
+They knew you--even when I brought you to the Red Lodge. They
+thought you were a spy."
+
+I turned to Kennedy. He had advanced and was leaning over to catch
+every word. Blair was standing behind me and she had not seen her
+husband yet. A quick glance showed me that he was trembling from
+head to foot like a leaf, as though he, too, were pursued by the
+nameless terror.
+
+"What did they do?" Kennedy asked in a low tone.
+
+Fearfully, gripping the bars of the iron bed, as though they were
+some tangible support for her mind, she answered: "They would get
+together. 'Now, all of you,' they said, 'unite yourselves in
+thought against our enemy, against Kennedy, that he must leave off
+persecuting us. He is ripe for destruction!'"
+
+Kennedy glanced sidewise at me, with a significant look.
+
+"God grant," she implored, "that none haunt me for what I have
+done in my ignorance!"
+
+Just then the door opened and my messenger entered, accompanied by
+Dr. Vaughn.
+
+I had turned to catch the expression on Blair's face just in time.
+It was a look of abject appeal.
+
+Before Dr. Vaughn could ask a question, or fairly take in the
+situation, Kennedy had faced him.
+
+"What was the purpose of all that elaborate mummery out at the Red
+Lodge?" asked Kennedy pointblank.
+
+I think I looked at Craig in no less amazement than Vaughn. In
+spite of the dramatic scenes through which we had passed, the
+spell of the occult had not fallen on him for an instant.
+
+"Mummery?" repeated Dr. Vaughn, bending his penetrating eyes on
+Kennedy, as if he would force him to betray himself first.
+
+"Yes," reiterated Craig. "You know as well as I do that it has
+been said that it is a well-established fact that the world wants
+to be deceived and is willing to pay for the privilege."
+
+Dr. Vaughn still gazed from one to the other of us defiantly.
+
+"You know what I mean," persisted Kennedy, "the mumbo-jumbo--just
+as the Haitian obi man sticks pins in a doll or melts a wax figure
+of his enemy. That is supposed to be an outward sign. But back of
+this terrible power that people believe moves in darkness and
+mystery is something tangible--something real."
+
+Dr. Vaughn looked up sharply at him, I think mistaking Kennedy's
+meaning. If he did, all doubt that Kennedy attributed anything to
+the supernatural was removed as he went on: "At first I had no
+explanation of the curious events I have just witnessed, and the
+more I thought about them, the more obscure did they seem.
+
+"I have tried to reason the thing out," he continued thoughtfully.
+"Did auto-suggestion, self-hypnotism explain what I have seen? Has
+Veda Blair been driven almost to death by her own fears only?"
+
+No one interrupted and he answered his own question. "Somehow the
+idea that it was purely fear that had driven her on did not
+satisfy me. As I said, I wanted something more tangible. I could
+not help thinking that it was not merely subjective. There was
+something objective, some force at work, something more than
+psychic in the result achieved by this criminal mental marauder,
+whoever it is."
+
+I was following Kennedy's reasoning now closely. As he proceeded,
+the point that he was making seemed more clear to me.
+
+Persons of a certain type of mind could be really mentally
+unbalanced by such methods which we had heard outlined, where the
+mere fact of another trying to exert power over them became known
+to them. They would, as a matter of fact, unbalance themselves,
+thinking about and fighting off imaginary terrors.
+
+Such people, I could readily see, might be quickly controlled, and
+in the wake of such control would follow stifled love, wrecked
+homes, ruined fortunes, suicide and even death.
+
+Dr. Vaughn leaned forward critically. "What did you conclude,
+then, was the explanation of what you saw last night?" he asked
+sharply.
+
+Kennedy met his question squarely, without flinching. "It looks to
+me," he replied quietly, "like a sort of hystero-epilepsy. It is
+well known, I believe, to demonologists--those who have studied
+this sort of thing. They have recognized the contortions, the
+screams, the wild, blasphemous talk, the cataleptic rigidity. They
+are epileptiform."
+
+Vaughn said nothing, but continued to weigh Kennedy as if in a
+balance. I, who knew him, knew that it would take a greater than
+Vaughn to find him wanting, once Kennedy chose to speak. As for
+Vaughn, was he trying to hide behind some technicality in medical
+ethics?
+
+"Dr. Vaughn," continued Craig, as if goading him to the point of
+breaking down his calm silence, "you are specialist enough to know
+these things as well, better than I do. You must know that
+epilepsy is one of the most peculiar diseases.
+
+"The victim may be in good physical condition, apparently. In
+fact, some hardly know that they have it. But it is something more
+than merely the fits. Always there is something wrong mentally. It
+is not the motor disturbance so much as the disturbance of
+consciousness."
+
+Kennedy was talking slowly, deliberately, so that none could drop
+a link in the reasoning.
+
+"Perhaps one in ten epileptics has insane periods, more or less,"
+he went on, "and there is no more dangerous form of insanity.
+Self-consciousness is lost, and in this state of automatism the
+worst of crimes have been committed without the subsequent
+knowledge of the patient. In that state they are no more
+responsible than are the actors in one's dreams."
+
+The hospital physician entered, accompanied by Craig's messenger,
+breathless. Craig almost seized the package from his hands and
+broke the seal.
+
+"Ah--this is what I wanted," he exclaimed, with an air of relief,
+forgetting for the time the exposition of the case that he was
+engaged in. "Here I have some anti-crotalus venine, of Drs.
+Flexner and Noguchi. Fortunately, in the city it is within easy
+reach."
+
+Quickly, with the aid of the physician he injected it into Veda's
+arm.
+
+"Of all substances in nature," he remarked, still at work over the
+unfortunate woman, "none is so little known as the venom of
+serpents."
+
+It was a startling idea which the sentence had raised in my mind.
+All at once I recalled the first remark of Seward Blair, in which
+he had repeated the password that had admitted us into the Red
+Lodge--"the Serpent's Tooth." Could it have been that she had
+really been bitten at some of the orgies by the serpent which they
+worshiped hideously hissing in its cage? I was sure that, at least
+until they were compelled, none would say anything about it. Was
+that the interpretation of the almost hypnotized look on Blair's
+face?
+
+"We know next to nothing of the composition of the protein bodies
+in the venoms which have such terrific, quick physiological
+effects," Kennedy was saying. "They have been studied, it is true,
+but we cannot really say that they are understood--or even that
+there are any adequate tests by which they can be recognized. The
+fact is, that snake venoms are about the safest of poisons for the
+criminal."
+
+Kennedy had scarcely propounded this startling idea when a car was
+heard outside. The Rapports had arrived, with the officer I had
+sent after them, protesting and threatening.
+
+They quieted down a bit as they entered, and after a quick glance
+around saw who was present.
+
+Professor Rapport gave one glance at the victim lying exhausted on
+the bed, then drew back, melodramatically, and cried, "The
+Serpent--the mark of the serpent!"
+
+For a moment Kennedy gazed full in the eyes of them all.
+
+"WAS it a snake bite?" he asked slowly, then, turning to Mrs.
+Blair, after a quick glance, he went on rapidly, "The first thing
+to ascertain is whether the mark consists of two isolated
+punctures, from the poison-conducting teeth or fangs of the snake,
+which are constructed like a hypodermic needle."
+
+The hospital physician had bent over her at the words, and before
+Kennedy could go on interrupted: "This was not a snake bite; it
+was more likely from an all-glass hypodermic syringe with a
+platinum-iridium needle."
+
+Professor Rapport, priest of the Devil, advanced a step menacingly
+toward Kennedy. "Remember," he said in a low, angry tone,
+"remember--you are pledged to keep the secrets of the Red Lodge!"
+
+Craig brushed aside the sophistry with a sentence. "I do not
+recognize any secrets that I have to keep about the meeting this
+afternoon to which you summoned the Blairs and Mrs. Langhorne,
+according to reports from the shadows I had placed on Mrs.
+Langhorne and Dr. Vaughn."
+
+If there is such a thing as the evil eye, Rapport's must have been
+a pair of them, as he realized that Kennedy had resorted to the
+simple devices of shadowing the devotees.
+
+A cry, almost a shriek, startled us. Kennedy's encounter with
+Rapport had had an effect which none of us had considered. The
+step or two in advance which the prophet had taken had brought him
+into the line of vision of the still half-stupefied Veda lying
+back of Kennedy on the hospital cot.
+
+The mere sight of him, the sound of his voice and the mention of
+the Red Lodge had been sufficient to penetrate that stupor. She
+was sitting bolt upright, a ghastly, trembling specter. Slowly a
+smile seemed to creep over the cruel face of the mystic. Was it
+not a recognition of his hypnotic power?
+
+Kennedy turned and laid a gentle hand on the quaking convulsed
+figure of the woman. One could feel the electric tension in the
+air, the battle of two powers for good or evil. Which would win--
+the old fascination of the occult or the new power of science?
+
+It was a dramatic moment. Yet not so dramatic as the outcome. To
+my surprise, neither won.
+
+Suddenly she caught sight of her husband. Her face changed. All
+the prehistoric jealousy of which woman is capable seemed to blaze
+forth.
+
+"I will defend myself!" she cried. "I will fight back! She shall
+not win--she shall not have you--no--she shall not--never!"
+
+I recalled the strained feeling between the two women that I had
+noticed in the cab. Was it Mrs. Langhorne who had been the
+disturbing influence, whose power she feared, over herself and
+over her husband?
+
+Rapport had fallen back a step, but not from the mind of Kennedy.
+
+"Here," challenged Craig, facing the group and drawing from his
+pocket the glass ampoule, "I picked this up at the Red Lodge last
+night."
+
+He held it out in his hand before the Rapports so that they could
+not help but see it. Were they merely good actors? They betrayed
+nothing, at least by face or action.
+
+"It is crotalin," he announced, "the venom of the rattlesnake--
+crotalus horridus. It has been noticed that persons suffering from
+certain diseases of which epilepsy is one, after having been
+bitten by a rattlesnake, if they recover from the snake bite, are
+cured of the disease."
+
+Kennedy was forging straight ahead now in his exposure.
+"Crotalin," he continued, "is one of the new drugs used in the
+treatment of epilepsy. But it is a powerful two-edged instrument.
+Some one who knew the drug, who perhaps had used it, has tried an
+artificial bite of a rattler on Veda Blair, not for epilepsy, but
+for another, diabolical purpose, thinking to cover up the crime,
+either as the result of the so-called death thought of the Lodge
+or as the bite of the real rattler at the Lodge."
+
+Kennedy had at last got under Dr. Vaughn's guard. All his
+reticence was gone.
+
+"I joined the cult," he confessed. "I did it in order to observe
+and treat one of my patients for epilepsy. I justified myself. I
+said, 'I will be the exposer, not the accomplice, of this modern
+Satanism.' I joined it and--"
+
+"There is no use trying to shield anyone, Vaughn," rapped out
+Kennedy, scarcely taking time to listen. "An epileptic of the most
+dangerous criminal type has arranged this whole elaborate setting
+as a plot to get rid of the wife who brought him his fortune and
+now stands in the way of his unholy love of Mrs. Langhorne. He
+used you to get the poison with which you treated him. He used the
+Rapports with money to play on her mysticism by their so-called
+death thought, while he watched his opportunity to inject the
+fatal crotalin."
+
+Craig faced the criminal, whose eyes now showed more plainly than
+words his deranged mental condition, and in a low tone added, "The
+Devil is in you, Seward Blair!"
+
+
+
+
+CHAPTER XXV
+
+THE "HAPPY DUST"
+
+
+Veda Blair's rescue from the strange use that was made of the
+venom came at a time when the city was aroused as it never had
+been before over the nation-wide agitation against drugs.
+
+Already, it will be recalled, Kennedy and I had had some recent
+experience with dope fiends of various kinds, but this case I set
+down because it drew us more intimately into the crusade.
+
+"I've called on you, Professor Kennedy, to see if I can't interest
+you in the campaign I am planning against drugs."
+
+Mrs. Claydon Sutphen, social leader and suffragist, had scarcely
+more than introduced herself when she launched earnestly into the
+reason for her visit to us.
+
+"You don't realize it, perhaps," she continued rapidly, "but very
+often a little silver bottle of tablets is as much a necessary to
+some women of the smart set as cosmetics."
+
+"I've heard of such cases," nodded Craig encouragingly.
+
+"Well, you see I became interested in the subject," she added,
+"when I saw some of my own friends going down. That's how I came
+to plan the campaign in the first place."
+
+She paused, evidently nervous. "I've been threatened, too," she
+went on, "but I'm not going to give up the fight. People think
+that drugs are a curse only to the underworld, but they have no
+idea what inroads the habit has made in the upper world, too. Oh,
+it is awful!" she exclaimed.
+
+Suddenly, she leaned over and whispered, "Why, there's my own
+sister, Mrs. Garrett. She began taking drugs after an operation,
+and now they have a terrible hold on her. I needn't try to conceal
+anything. It's all been published in the papers--everybody knows
+it. Think of it--divorced, disgraced, all through these cursed
+drugs! Dr. Coleman, our family physician, has done everything
+known to break up the habit, but he hasn't succeeded."
+
+Dr. Coleman, I knew, was a famous society physician. If he had
+failed, I wondered why she thought a detective might succeed. But
+it was evidently another purpose she had in mind in introducing
+the subject.
+
+"So you can understand what it all means to me, personally," she
+resumed, with a sigh. "I've studied the thing--I've been forced to
+study it. Why, now the exploiters are even making drug fiends of
+mere--children!"
+
+Mrs. Sutphen spread out a crumpled sheet of note paper before us
+on which was written something in a trembling scrawl. "For
+instance, here's a letter I received only yesterday."
+
+Kennedy glanced over it carefully. It was signed "A Friend," and
+read:
+
+"I have heard of your drug war in the newspapers and wish to help
+you, only I don't dare to do so openly. But I can assure you that
+if you will investigate what I am about to tell you, you will soon
+be on the trail of those higher up in this terrible drug business.
+There is a little center of the traffic on West 66th Street, just
+off Broadway. I cannot tell you more, but if you can investigate
+it, you will be doing more good than you can possibly realize now.
+There is one girl there, whom they call 'Snowbird.' If you could
+only get hold of her quietly and place her in a sanitarium you
+might save her yet."
+
+Craig was more than ordinarily interested. "And the children--what
+did you mean by that?"
+
+"Why, it's literally true," asserted Mrs. Sutphen in a horrified
+tone. "Some of the victims are actually school children. Up there
+in 66th Street we have found a man named Armstrong, who seems to
+be very friendly with this young girl whom they call 'Snowbird.'
+Her real name, by the way, is Sawtelle, I believe. She can't be
+over eighteen, a mere child, yet she's a slave to the stuff."
+
+"Oh, then you have actually already acted on the hint in the
+letter?" asked Craig.
+
+"Yes," she replied, "I've had one of the agents of our Anti-Drug
+Society, a social worker, investigating the neighborhood."
+
+Kennedy nodded for her to go on.
+
+"I've even investigated myself a little, and now I want to employ
+some one to break the thing up. My husband had heard of you and so
+here I am. Can you help me?"
+
+There was a note of appeal in her voice that was irresistible to a
+man who had the heart of Kennedy.
+
+"Tell me just what you have discovered so far," he asked simply.
+
+"Well," she replied slowly, "after my agent verified the contents
+of the letter, I watched until I saw this girl--she's a mere
+child, as I said--going to a cabaret in the neighborhood. What
+struck me was that I saw her go in looking like a wreck and come
+out a beautiful creature, with bright eyes, flushed cheeks, almost
+youthful again. A most remarkable girl she is, too," mused Mrs.
+Sutphen, "who always wears a white gown, white hat, white shoes
+and white stockings. It must be a mania with her."
+
+Mrs. Sutphen seemed to have exhausted her small store of
+information, and as she rose to go Kennedy rose also. "I shall be
+glad to look into the case, Mrs. Sutphen," he promised. "I'm sure
+there is something that can be done--there must be."
+
+"Thank you, ever so much," she murmured, as she paused at the
+door, something still on her mind. "And perhaps, too," she added,
+"you may run across my sister, Mrs. Garrett."
+
+"Indeed," he assured her, "if there is anything I can possibly do
+that will assist you personally, I shall be only too happy to do
+it."
+
+"Thank you again, ever so much," she repeated with just a little
+choke in her voice.
+
+For several moments Kennedy sat contemplating the anonymous letter
+which she had left with him, studying both its contents and the
+handwriting.
+
+"We must go over the ground up there again," he remarked finally.
+"Perhaps we can do better than Mrs. Sutphen and her drug
+investigator have done."
+
+Half an hour later we had arrived and were sauntering along the
+street in question, walking slowly up and down in the now fast-
+gathering dusk. It was a typical cheap apartment block of
+variegated character, with people sitting idly on the narrow front
+steps and children spilling out into the roadway in imminent
+danger of their young lives from every passing automobile.
+
+On the crowded sidewalk a creation in white hurtled past us. One
+glance at the tense face in the flickering arc light was enough
+for Kennedy. He pulled my arm and we turned and followed at a safe
+distance.
+
+She looked like a girl who could not have been more than eighteen,
+if she was as old as that. She was pretty, too, but already her
+face was beginning to look old and worn from the use of drugs. It
+was unmistakable.
+
+In spite of the fact that she was hurrying, it was not difficult
+to follow her in the crowd, as she picked her way in and out, and
+finally turned into Broadway where the white lights were welcoming
+the night.
+
+Under the glare of a huge electric sign she stopped a moment, then
+entered one of the most notorious of the cabarets.
+
+We entered also at a discreet distance and sat down at a table.
+
+"Don't look around, Walter," whispered Craig, as the waiter took
+our order, "but to your right is Mrs. Sutphen."
+
+If he had mentioned any other name in the world, I could not have
+been more surprised. I waited impatiently until I could pick her
+out from the corner of my eye. Sure enough, it was Mrs. Sutphen
+and another woman. What they were doing there I could not imagine,
+for neither had the look of habitues of such a place.
+
+I followed Kennedy's eye and found that he was gazing furtively at
+a flashily dressed young man who was sitting alone at the far end
+in a sort of booth upholstered in leather.
+
+The girl in white, whom I was now sure was Miss Sawtelle, went
+over and greeted him. It was too far to see just what happened,
+but the young woman after sitting down rose and left almost
+immediately. As nearly as I could make out, she had got something
+from him which she had dropped into her handbag and was now
+hugging the handbag close to herself almost as if it were gold.
+
+We sat for a few minutes debating just what to do, when Mrs.
+Sutphen and her friend rose. As she passed out, a quick, covert
+glance told us to follow. We did so and the two turned into
+Broadway.
+
+"Let me present you to Miss McCann," introduced Mrs. Sutphen as we
+caught up with them. "Miss McCann is a social worker and trained
+investigator whom I'm employing."
+
+We bowed, but before we could ask a question, Mrs. Sutphen cried
+excitedly: "I think I have a clue, anyway. We've traced the source
+of the drugs at least as far as that young fellow, 'Whitecap,'
+whom you saw in there."
+
+I had not recognized his face, although I had undoubtedly seen
+pictures of him before. But no sooner had I heard the name than I
+recognized it as that of one of the most notorious gang leaders on
+the West Side.
+
+Not only that, but Whitecap's gang played an important part in
+local politics. There was scarcely a form of crime or vice to
+which Whitecap and his followers could not turn a skilled hand,
+whether it was swinging an election, running a gambling club, or
+dispensing "dope."
+
+"You see," she explained, "even before I saw you, my suspicions
+were aroused and I determined to obtain some of the stuff they are
+using up here, if possible. I realized it would be useless for me
+to try to get it myself, so I got Miss McCann from the
+Neighborhood House to try it. She got it and has turned the bottle
+over to me."
+
+"May I see it?" asked Craig eagerly.
+
+Mrs. Sutphen reached hastily into her handbag, drew forth a small
+brown glass bottle and handed it to him. Craig retreated into one
+of the less dark side streets. There he pulled out the paraffinned
+cork from the bottle, picked out a piece of cotton stuffed in the
+neck of the bottle and poured out some flat tablets that showed a
+glistening white in the palm of his hand. For an instant he
+regarded them.
+
+"I may keep these?" he asked.
+
+"Certainly," replied Mrs. Sutphen. "That's what I had Miss McCann
+get them for."
+
+Kennedy dropped the bottle into his pocket.
+
+"So that was the gang leader, 'Whitecap,'" he remarked as we
+turned again to Broadway.
+
+"Yes," replied Mrs. Sutphen. "At certain hours, I believe he can
+be found at that cabaret selling this stuff, whatever it is, to
+anyone who comes properly introduced. The thing seems to be so
+open and notorious that it amounts to a scandal."
+
+We parted a moment later, Mrs. Sutphen and Miss McCann to go to
+the settlement house, Craig and I to continue our investigations.
+
+"First of all, Walter," he said as we swung aboard an uptown car,
+"I want to stop at the laboratory."
+
+In his den, which had been the scene of so many triumphs, Kennedy
+began a hasty examination of the tablets, powdering one and
+testing it with one chemical after another.
+
+"What are they?" I asked at length when he seemed to have found
+the right reaction which gave him the clue.
+
+"Happy dust," he answered briefly.
+
+"Happy dust?" I repeated, looking at him a moment in doubt as to
+whether he was joking or serious. "What is that?"
+
+"The Tenderloin name for heroin--a comparatively new derivative of
+morphine. It is really morphine treated with acetic acid which
+renders it more powerful than morphine alone."
+
+"How do they take them? What's the effect?" I asked.
+
+"The person who uses heroin usually powders the tablets and snuffs
+the powder up the nose," he answered. "In a short time, perhaps
+only two or three weeks, one can become a confirmed victim of
+'happy dust.' And while one is under its influence he is morally,
+physically and mentally irresponsible."
+
+Kennedy was putting away the paraphernalia he had used, meanwhile
+talking about the drug. "One of the worst aspects of it, too," he
+continued, "is the desire of the user to share his experience with
+some one else. This passing on of the habit, which seems to be one
+of the strongest desires of the drug fiend, makes him even more
+dangerous to society than he would otherwise be. It makes it
+harder for anyone once addicted to a drug to shake it off, for his
+friends will give him no chance. The only thing to do is to get
+the victim out of his environment and into an entirely new scene."
+
+The laboratory table cleared again, Kennedy had dropped into a
+deep study.
+
+"Now, why was Mrs. Sutphen there?" he asked aloud. "I can't think
+it was solely through her interest for that girl they call
+Snowbird. She was interested in her, but she made no attempt to
+interfere or to follow her. No, there must have been another
+reason."
+
+"You don't think she's a dope fiend herself, do you?" I asked
+hurriedly.
+
+Kennedy smiled. "Hardly, Walter. If she has any obsession on the
+subject, it is more likely to lead her to actual fanaticism
+against all stimulants and narcotics and everything connected with
+them. No, you might possibly persuade me that two and two equal
+five--but not seventeen. It's not very late. I think we might make
+another visit to that cabaret and see whether the same thing is
+going on yet."
+
+
+
+
+CHAPTER XXVI
+
+THE BINET TEST
+
+
+We rode downtown again and again sauntered in, this time with the
+theater crowd. Our first visit had been so quiet and
+unostentatious that the second attracted no attention or comment
+from the waiters, or anyone else.
+
+As we sat down we glanced over, and there in his corner still was
+Whitecap. Apparently his supply of the dope was inexhaustible, for
+he was still dispensing it. As we watched the tenderloin habitues
+come and go, I came soon to recognize the signs by the mere look
+on the face--the pasty skin, the vacant eye, the nervous quiver of
+the muscles as though every organ and every nerve were crying out
+for more of the favorite nepenthe. Time and again I noticed the
+victims as they sat at the tables, growing more and more haggard
+and worn, until they could stand it no longer. Then they would
+retire, sometimes after a visit across the floor to Whitecap, more
+often directly, for they had stocked themselves up with the drug
+evidently after the first visit to him. But always they would come
+back, changed in appearance, with what seemed to be a new lease of
+life, but nevertheless still as recognizable as drug victims.
+
+It was not long, as we waited, before another woman, older than
+Miss Sawtelle, but dressed in an extreme fashion, hurried into the
+cabaret and with scarcely a look to right or left went directly to
+Whitecap's corner. I noticed that she, too, had the look.
+
+There was a surreptitious passing of a bottle in exchange for a
+treasury note, and she dropped into the seat beside him.
+
+Before he could interfere, she had opened the bottle, crushed a
+tablet or two in a napkin, and was holding it to her face as
+though breathing the most exquisite perfume. With one quick
+inspiration of her breath after another, she was snuffing the
+powder up her nose.
+
+Whitecap with an angry gesture pulled the napkin from her face,
+and one could fancy his snarl under his breath, "Say--do you want
+to get me in wrong here?"
+
+But it was too late. Some at least of the happy dust had taken
+effect, at least enough to relieve the terrible pangs she must
+have been suffering.
+
+As she rose and retired, with a hasty apology to Whitecap for her
+indiscretion, Kennedy turned to me and exclaimed, "Think of it.
+The deadliest of all habits is the simplest. No hypodermic; no
+pipe; no paraphernalia of any kind. It's terrible."
+
+She returned to sit down and enjoy herself, careful not to obtrude
+herself on Whitecap lest he might become angry at the mere sight
+of her and treasure his anger up against the next time when she
+would need the drug.
+
+Already there was the most marvelous change in her. She seemed
+captivated by the music, the dancing, the life which a few moments
+before she had totally disregarded.
+
+She was seated alone, not far from us, and as she glanced about
+Kennedy caught her eye. She allowed her gaze to rest on us for a
+moment, the signal for a mild flirtation which ended in our
+exchange of tables and we found ourselves opposite the drug fiend,
+who was following up the taking of the dope by a thin-stemmed
+glass of a liqueur.
+
+I do not recall the conversation, but it was one of those
+inconsequential talks that Bohemians consider so brilliant and
+everybody else so vapid. As we skimmed from one subject to
+another, treating the big facts of life as if they were mere
+incidents and the little as if they overshadowed all else, I could
+see that Craig, who had a faculty of probing into the very soul of
+anyone, when he chose, was gradually leading around to a subject
+which I knew he wanted, above all others, to discuss.
+
+It was not long before, as the most natural remark in the world
+following something he had made her say, just as a clever
+prestidigitator forces a card, he asked, "What was it I saw you
+snuffing over in the booth--happy dust?"
+
+She did not even take the trouble to deny it, but nodded a brazen
+"Yes." "How did you come to use it first?" he asked, careful not
+to give offense in either tone or manner.
+
+"The usual way, I suppose," she replied with a laugh that sounded
+harsh and grating. "I was ill and I found out what it was the
+doctor was giving me."
+
+"And then?"
+
+"Oh, I thought I would use it only as long as it served my purpose
+and, when that was over, give it up."
+
+"But--?" prompted Craig hypnotically.
+
+"Instead, I was soon using six, eight, ten tablets of heroin a
+day. I found that I needed that amount in order to live. Then it
+went up by leaps to twenty, thirty, forty."
+
+"Suppose you couldn't get it, what then?"
+
+"Couldn't get it?" she repeated with an unspeakable horror. "Once
+I thought I'd try to stop. But my heart skipped beats; then it
+seemed to pound away, as if trying to break through my ribs. I
+don't think heroin is like other drugs. When one has her 'coke'--
+that's cocaine--taken away, she feels like a rag. Fill her up and
+she can do anything again. But, heroin--I think one might murder
+to get it!"
+
+The expression on the woman's face was almost tragic. I verily
+believe that she meant it.
+
+"Why," she cried, "if anyone had told me a year ago that the time
+would ever come when I would value some tiny white tablets above
+anything else in the world, yes, and even above my immortal soul,
+I would have thought him a lunatic."
+
+It was getting late, and as the woman showed no disposition to
+leave, Kennedy and I excused ourselves.
+
+Outside Craig looked at me keenly. "Can you guess who that was?"
+
+"Although she didn't tell us her name," I replied, "I am morally
+certain that it was Mrs. Garrett."
+
+"Precisely," he answered, "and what a shame, too, for she must
+evidently once have been a woman of great education and
+refinement."
+
+He shook his head sadly. "Walter, there isn't likely to be
+anything that we can do for some hours now. I have a little
+experiment I'd like to make. Suppose you publish for me a story in
+the Star about the campaign against drugs. Tell about what we have
+seen to-night, mention the cabaret by indirection and Whitecap
+directly. Then we can sit back and see what happens. We've got to
+throw a scare into them somehow, if we are going to smoke out
+anyone higher up than Whitecap. But you'll have to be careful, for
+if they suspect us our usefulness in the case will be over."
+
+Together, Kennedy and I worked over our story far into the night
+down at the Star office, and the following day waited to see
+whether anything came of it.
+
+It was with a great deal of interest tempered by fear that we
+dropped into the cabaret the following evening. Fortunately no one
+suspected us. In fact, having been there the night before, we had
+established ourselves, as it were, and were welcomed as old
+patrons and good spenders.
+
+I noticed, however, that Whitecap was not there. The story had
+been read by such of the dope fiends as had not fallen too far to
+keep abreast of the times and these and the waiters were busy
+quietly warning off a line of haggard-eyed, disappointed patrons
+who came around, as usual.
+
+Some of them were so obviously dependent on Whitecap that I almost
+regretted having written the story, for they must have been
+suffering the tortures of the damned.
+
+It was in the midst of a reverie of this sort that a low
+exclamation from Kennedy recalled my attention. There was Snowbird
+with a man considerably older than herself. They had just come in
+and were looking about frantically for Whitecap. But Whitecap had
+been too frightened by the story in the Star to sell any more of
+the magic happy dust openly in the cabaret, at least.
+
+The pair, nerve-racked and exhausted, sat down mournfully in a
+seat near us, and as they talked earnestly in low tones we had an
+excellent opportunity for studying Armstrong for the first time.
+
+He was not a bad-looking man, or even a weak one. In back of the
+dissipation of the drugs one fancied he could read the story of a
+brilliant life wrecked. But there was little left to admire or
+respect. As the couple talked earnestly, the one so old, the other
+so young in vice, I had to keep a tight rein on myself to prevent
+my sympathy for the wretched girl getting the better of common
+sense and kicking the older man out of doors.
+
+Finally Armstrong rose to go, with a final imploring glance from
+the girl. Obviously she had persuaded him to forage about to
+secure the heroin, by hook or crook, now that the accustomed
+source of supply was cut off so suddenly.
+
+It was also really our first chance to study the girl carefully
+under the light, for her entrance and exit the night before had
+been so hurried that we had seen comparatively little of her.
+Craig was watching her narrowly. Not only were the effects of the
+drug plainly evident on her face, but it was apparent that the
+snuffing the powdered tablets was destroying the bones in her
+nose, through shrinkage of the blood vessels, as well as
+undermining the nervous system and causing the brain to totter.
+
+I was wondering whether Armstrong knew of any depot for the secret
+distribution of the drug. I could not believe that Whitecap was
+either the chief distributer or the financial head of the illegal
+traffic. I wondered who indeed was the man higher up. Was he an
+importer of the drug, or was he the representative of some
+chemical company not averse to making an illegal dollar now and
+then by dragging down his fellow man?
+
+Kennedy and I were trying to act as if we were enjoying the
+cabaret show and not too much interested in the little drama that
+was being acted before us. I think little Miss Sawtelle noticed,
+however, that we were looking often her way. I was amazed, too, on
+studying her more closely to find that there was something
+indefinably queer about her, aside from the marked effect of the
+drugs she had been taking. What it was I was at a loss to
+determine, but I felt sure from the expression on Kennedy's face
+that he had noticed it also.
+
+I was on the point of asking him if he, too, observed anything
+queer in the girl, when Armstrong hurried in and handed her a
+small package, then almost without a word stalked out again,
+evidently as much to Snowbird's surprise as to our own.
+
+She had literally seized the package, as though she were drowning
+and grasping at a life buoy. Even the surprise at his hasty
+departure could not prevent her, however, from literally tearing
+the wrapper off, and in the sheltering shadow of the table cloth
+pouring forth the little white pellets in her lap, counting them
+as a miser counts his gold,
+
+"The old thief!" she exclaimed aloud. "He's held out twenty-five!"
+
+I don't know which it was that amazed me most, the almost childish
+petulance and ungovernable temper of the girl which made her cry
+out in spite of her surroundings and the circumstances, or the
+petty rapacity of the man who could stoop to such a low level as
+to rob her in this seeming underhand manner.
+
+There was no time for useless repining now. The call of outraged
+nature for its daily and hourly quota of poison was too
+imperative. She dumped the pellets back into the bottle hastily,
+and disappeared.
+
+When she came back, it was with that expression I had come to know
+so well. At least for a few hours there was a respite for her from
+the terrific pangs she had been suffering. She was almost happy,
+smiling. Even that false happiness, I felt, was superior to
+Armstrong's moral sense blunted by drugs. I had begun to realize
+how lying, stealing, crimes of all sorts might be laid at the door
+of this great evil.
+
+In her haste to get where she could snuff the heroin she had
+forgotten a light wrap lying on her chair. As she returned for it,
+it fell to the floor. Instantly Kennedy was on his feet, bending
+over to pick it up.
+
+She thanked him, and the smile lingered a moment on her face. It
+was enough. It gave Kennedy the chance to pursue a conversation,
+and in the free and easy atmosphere of the cabaret to invite her
+to sit over at our table.
+
+At least all her nervousness was gone and she chatted vivaciously.
+Kennedy said little. He was too busy watching her. It was quite
+the opposite of the case of Mrs. Garrett. Yet I was at a loss to
+define what it was that I sensed.
+
+Still the minutes sped past and we seemed to be getting on
+famously. Unlike his action in the case of the older woman where
+he had been sounding the depths of her heart and mind, in this
+case his idea seemed to be to allow the childish prattle to come
+out and perhaps explain itself.
+
+However, at the end of half an hour when we seemed to be getting
+no further along, Kennedy did not protest at her desire to leave
+us, "to keep a date," as she expressed it.
+
+"Waiter, the check, please," ordered Kennedy leisurely.
+
+When he received it, he seemed to be in no great hurry to pay it,
+but went over one item after another, then added up the footing
+again.
+
+"Strange how some of these waiters grow rich?" Craig remarked
+finally with a gay smile.
+
+The idea of waiters and money quickly brought some petty
+reminiscences to her mind. While she was still talking, Craig
+casually pulled a pencil out of his pocket and scribbled some
+figures on the back of the waiter's check.
+
+From where I was sitting beside him, I could see that he had
+written some figures similar to the following:
+
+5183 47395 654726 2964375 47293815 924738651 2146073859
+
+"Here's a stunt," he remarked, breaking into the conversation at a
+convenient point. "Can you repeat these numbers after me?"
+
+Without waiting for her to make excuse, he said quickly "5183."
+"5183," she repeated mechanically.
+
+"47395," came in rapid succession, to which she replied, perhaps a
+little slower than before,
+
+"47395."
+
+"Now, 654726," he said.
+
+"654726," she repeated, I thought with some hesitation.
+
+"Again, 2964375," he shot out.
+
+"269," she hesitated, "73--" she stopped.
+
+It was evident that she had reached the limit.
+
+Kennedy smiled, paid the check and we parted at the door.
+
+"What was all that rigmarole?" I inquired as the white figure
+disappeared down the street.
+
+"Part of the Binet test, seeing how many digits one can remember.
+An adult ought to remember from eight to ten, in any order. But
+she has the mentality of a child. That is the queer thing about
+her. Chronologically she may be eighteen years or so old. Mentally
+she is scarcely more than eight. Mrs. Sutphen was right. They have
+made a fiend out of a mere child--a defective who never had a
+chance against them."
+
+
+
+
+CHAPTER XXVII
+
+THE LIE DETECTOR
+
+
+As the horror of it all dawned on me, I hated Armstrong worse than
+ever, hated Whitecap, hated the man higher up, whoever he might
+be, who was enriching himself out of the defective, as well as the
+weakling, and the vicious--all three typified by Snowbird,
+Armstrong and Whitecap.
+
+Having no other place to go, pending further developments of the
+publicity we had given the drug war in the Star, Kennedy and I
+decided on a walk home in the bracing night air.
+
+We had scarcely entered the apartment when the hall boy called to
+us frantically: "Some one's been trying to get you all over town,
+Professor Kennedy. Here's the message. I wrote it down. An attempt
+has been made to poison Mrs. Sutphen. They said at the other end
+of the line that you'd know."
+
+We faced each other aghast.
+
+"My God!" exclaimed Kennedy. "Has that been the effect of our
+story, Walter? Instead of smoking out anyone--we've almost killed
+some one."
+
+As fast as a cab could whisk us around to Mrs. Sutphen's we
+hurried.
+
+"I warned her that if she mixed up in any such fight as this she
+might expect almost anything," remarked Mr. Sutphen nervously, as
+he met us in the reception room. "She's all right, now, I guess,
+but if it hadn't been for the prompt work of the ambulance surgeon
+I sent for, Dr. Coleman says she would have died in fifteen
+minutes."
+
+"How did it happen?" asked Craig.
+
+"Why, she usually drinks a glass of vichy and milk before
+retiring," replied Mr. Sutphen. "We don't know yet whether it was
+the vichy or the milk that was poisoned, but Dr. Coleman thinks it
+was chloral in one or the other, and so did the ambulance surgeon.
+I tell you I was scared. I tried to get Coleman, but he was out on
+a case, and I happened to think of the hospitals as probably the
+quickest. Dr. Coleman came in just as the young surgeon was
+bringing her around. He--oh, here he is now."
+
+The famous doctor was just coming downstairs. He saw us, but, I
+suppose, inasmuch as we did not belong to the Sutphen and Coleman
+set, ignored us. "Mrs. Sutphen will be all right now," he said
+reassuringly as he drew on his gloves. "The nurse has arrived, and
+I have given her instructions what to do. And, by the way, my dear
+Sutphen, I should advise you to deal firmly with her in that
+matter about which her name is appearing in the papers. Women
+nowadays don't seem to realize the dangers they run in mixing in
+in all these reforms. I have ordered an analysis of both the milk
+and vichy, but that will do little good unless we can find out who
+poisoned it. And there are so many chances for things like that,
+life is so complex nowadays--"
+
+He passed out with scarcely a nod at us. Kennedy did not attempt
+to question him. He was thinking rapidly.
+
+"Walter, we have no time to lose," he exclaimed, seizing a
+telephone that stood on a stand near by. "This is the time for
+action. Hello--Police Headquarters, First Deputy O'Connor,
+please."
+
+As Kennedy waited I tried to figure out how it could have
+happened. I wondered whether it might not have been Mrs. Garrett.
+Would she stop at anything if she feared the loss of her favorite
+drug? But then there were so many others and so many ways of
+"getting" anybody who interfered with the drug traffic that it
+seemed impossible to figure it out by pure deduction.
+
+"Hello, O'Connor," I heard Kennedy say; "you read that story in
+the Star this morning about the drug fiends at that Broadway
+cabaret? Yes? Well, Jameson and I wrote it. It's part of the drug
+war that Mrs. Sutphen has been waging. O'Connor, she's been
+poisoned--oh, no--she's all right now. But I want you to send out
+and arrest Whitecap and that fellow Armstrong immediately. I'm
+going to put them through a scientific third degree up in the
+laboratory to-night. Thank you. No--no matter how late it is,
+bring them up."
+
+Dr. Coleman had gone long since, Mr. Sutphen had absolutely no
+interest further than the recovery of Mrs. Sutphen just now, and
+Mrs. Sutphen was resting quietly and could not be seen.
+Accordingly Kennedy and I hastened up to the laboratory to wait
+until O'Connor could "deliver the goods."
+
+It was not long before one of O'Connor's men came in with
+Whitecap.
+
+"While we're waiting," said Craig, "I wish you would just try this
+little cut-out puzzle."
+
+I don't know what Whitecap thought, but I know I looked at Craig's
+invitation to "play blocks" as a joke scarcely higher in order
+than the number repetition of Snowbird. Whitecap did it, however,
+sullenly, and under compulsion, in, I should say about two
+minutes.
+
+"I have Armstrong here myself," called out the voice of our old
+friend O'Connor, as he burst into the room.
+
+"Good!" exclaimed Kennedy. "I shall be ready for him in just a
+second. Have Whitecap held here in the anteroom while you bring
+Armstrong into the laboratory. By the way, Walter, that was
+another of the Binet tests, putting a man at solving puzzles. It
+involves reflective judgment, one of the factors in executive
+ability. If Whitecap had been defective, it would have taken him
+five minutes to do that puzzle, if at all. So you see he is not in
+the class with Miss Sawtelle. The test shows him to be shrewd. He
+doesn't even touch his own dope. Now for Armstrong."
+
+I knew enough of the underworld to set Whitecap down, however, as
+a "lobbygow"--an agent for some one higher up, recruiting both the
+gangs and the ranks of street women.
+
+Before us, as O'Connor led in Armstrong, was a little machine with
+a big black cylinder. By means of wires and electrodes Kennedy
+attached it to Armstrong's chest.
+
+"Now, Armstrong," he began in an even tone, "I want you to tell
+the truth--the whole truth. You have been getting heroin tablets
+from Whitecap."
+
+"Yes, sir," replied the dope fiend defiantly.
+
+"To-day you had to get them elsewhere."
+
+No answer.
+
+"Never mind," persisted Kennedy, still calm, "I know. Why,
+Armstrong, you even robbed that girl of twenty-five tablets."
+
+"I did not," shot out the answer.
+
+"There were twenty-five short," accused Kennedy.
+
+The two faced each other. Craig repeated his remark.
+
+"Yes," replied Armstrong, "I held out the tablets, but it was not
+for myself, I can get all I want. I did it because I didn't want
+her to get above seventy-five a day. I have tried every way to
+break her of the habit that has got me--and failed. But seventy-
+five--is the limit!"
+
+"A pretty story!" exclaimed O'Connor.
+
+Craig laid his hand on his arm to check him, as he examined a
+record registered on the cylinder of the machine.
+
+"By the way, Armstrong, I want you to write me out a note that I
+can use to get a hundred heroin tablets. You can write it all but
+the name of the place where I can get them."
+
+Armstrong was on the point of demurring, but the last sentence
+reassured him. He would reveal nothing by it--yet.
+
+Still the man was trembling like a leaf. He wrote:
+
+"Give Whitecap one hundred shocks--A Victim."
+
+For a moment Kennedy studied the note carefully. "Oh--er--I
+forgot, Armstrong, but a few days ago an anonymous letter was sent
+to Mrs. Sutphen, signed 'A Friend.' Do you know anything about
+it?"
+
+"A note?" the man repeated. "Mrs. Sutphen? I don't know anything
+about any note, or Mrs. Sutphen either."
+
+Kennedy was still studying his record. "This," he remarked slowly,
+"is what I call my psychophysical test for falsehood. Lying, when
+it is practiced by an expert, is not easily detected by the most
+careful scrutiny of the liar's appearance and manner.
+
+"However, successful means have been developed for the detection
+of falsehood by the study of experimental psychology. Walter, I
+think you will recall the test I used once, the psychophysical
+factor of the character and rapidity of the mental process known
+as the association of ideas?"
+
+I nodded acquiescence.
+
+"Well," he resumed, "in criminal jurisprudence, I find an even
+more simple and more subjective test which has been recently
+devised. Professor Stoerring of Bonn has found out that feelings
+of pleasure and pain produce well-defined changes in respiration.
+Similar effects are produced by lying, according to the famous
+Professor Benussi of Graz.
+
+"These effects are unerring, unequivocal. The utterance of a false
+statement increases respiration; of a true statement decreases.
+The importance and scope of these discoveries are obvious."
+
+Craig was figuring rapidly on a piece of paper. "This is a certain
+and objective criterion," he continued as he figured, "between
+truth and falsehood. Even when a clever liar endeavors to escape
+detection by breathing irregularly, it is likely to fail, for
+Benussi has investigated and found that voluntary changes in
+respiration don't alter the result. You see, the quotient obtained
+by dividing the time of inspiration by the time of expiration
+gives me the result."
+
+He looked up suddenly. "Armstrong, you are telling the truth about
+some things--downright lies about others. You are a drug fiend--
+but I will be lenient with you, for one reason. Contrary to
+everything that I would have expected, you are really trying to
+save that poor half-witted girl whom you love from the terrible
+habit that has gripped you. That is why you held out the quarter
+of the one hundred tablets. That is why you wrote the note to Mrs.
+Sutphen, hoping that she might be treated in some institution."
+
+Kennedy paused as a look of incredulity passed over Armstrong's
+face.
+
+"Another thing you said was true," added Kennedy. "You can get all
+the heroin you want. Armstrong, you will put the address of that
+place on the outside of the note, or both you and Whitecap go to
+jail. Snowbird will be left to her own devices--she can get all
+the 'snow,' as some of you fiends call it, that she wants from
+those who might exploit her."
+
+"Please, Mr. Kennedy," pleaded Armstrong.
+
+"No," interrupted Craig, before the drug fiend could finish. "That
+is final. I must have the name of that place."
+
+In a shaky hand Armstrong wrote again. Hastily Craig stuffed the
+note into his pocket, and ten minutes later we were mounting the
+steps of a big brownstone house on a fashionable side street just
+around the corner from Fifth Avenue.
+
+As the door was opened by an obsequious colored servant, Craig
+handed him the scrap of paper signed by the password, "A Victim."
+
+Imitating the cough of a confirmed dope user, Craig was led into a
+large waiting room.
+
+"You're in pretty bad shape, sah," commented the servant.
+
+Kennedy nudged me and, taking the cue, I coughed myself red in the
+face.
+
+"Yes," he said. "Hurry--please."
+
+The servant knocked at a door, and as it was opened we caught a
+glimpse of Mrs. Garrett in negligee.
+
+"What is it, Sam?" she asked.
+
+"Two gentlemen for some heroin tablets, ma'am."
+
+"Tell them to go to the chemical works--not to my office, Sam,"
+growled a man's voice inside.
+
+With a quick motion, Kennedy had Mrs. Garrett by the wrist.
+
+"I knew it," he ground out. "It was all a fake about how you got
+the habit. You wanted to get it, so you could get and hold him.
+And neither one of you would stop at anything, not even the murder
+of your sister, to prevent the ruin of the devilish business you
+have built up in manufacturing and marketing the stuff."
+
+He pulled the note from the hand of the surprised negro. "I had
+the right address, the place where you sell hundreds of ounces of
+the stuff a week--but I preferred to come to the doctor's office
+where I could find you both."
+
+Kennedy had firmly twisted her wrist until, with a little scream
+of pain, she let go the door handle. Then he gently pushed her
+aside, and the next instant Craig had his hand inside the collar
+of Dr. Coleman, society physician, proprietor of the Coleman
+Chemical Works downtown, the real leader of the drug gang that was
+debauching whole sections of the metropolis.
+
+
+
+
+CHAPTER XXVIII
+
+THE FAMILY SKELETON
+
+
+Surprised though we were at the unmasking of Dr. Coleman, there
+was nothing to do but to follow the thing out. In such cases we
+usually ran into the greatest difficulty--organized vice. This was
+no exception.
+
+Even when cases involved only a clever individual or a prominent
+family, it was the same. I recall, for example, the case of a
+well-known family in a New York suburb, which was particularly
+difficult. It began in a rather unusual manner, too.
+
+"Mr. Kennedy--I am ruined--ruined."
+
+It was early one morning that the telephone rang and I answered
+it. A very excited German, breathless and incoherent, was
+evidently at the other end of the wire.
+
+I handed the receiver to Craig and picked up the morning paper
+lying on the table.
+
+"Minturn--dead?" I heard Craig exclaim. "In the paper this
+morning? I'll be down to see you directly."
+
+Kennedy almost tore the paper from me. In the next to the end
+column where late news usually is dropped was a brief account of
+the sudden death of Owen Minturn, one of the foremost criminal
+lawyers of the city, in Josephson's Baths downtown.
+
+It ended: "It is believed by the coroner that Mr. Minturn was
+shocked to death and evidence is being sought to show that two
+hundred and forty volts of electricity had been thrown into the
+attorney's body while he was in the electric bath. Joseph
+Josephson, the proprietor of the bath, who operated the
+switchboard, is being held, pending the completion of the
+inquiry."
+
+As Kennedy hastily ran his eye over the paragraphs, he became more
+and more excited himself.
+
+"Walter," he cried, as he finished, "I don't believe that that was
+an accident at all."
+
+"Why?" I asked.
+
+He already had his hat on, and I knew he was going to Josephson's
+breakfastless. I followed reluctantly.
+
+"Because," he answered, as we hustled along in the early morning
+crowd, "it was only yesterday afternoon that I saw Minturn at his
+office and he made an appointment with me for this very morning.
+He was a very secretive man, but he did tell me this much, that he
+feared his life was in danger and that it was in some way
+connected with that Pearcy case up in Stratfield, Connecticut,
+where he has an estate. You have read of the case?"
+
+Indeed I had. It had seemed to me to be a particularly
+inexplicable affair. Apparently a whole family had been poisoned
+and a few days before old Mr. Randall Pearcy, a retired
+manufacturer, had died after a brief but mysterious illness.
+
+Pearcy had been married a year or so ago to Annette Oakleigh, a
+Broadway comic opera singer, who was his second wife. By his first
+marriage he had had two children, a son, Warner, and a daughter,
+Isabel.
+
+Warner Pearcy, I had heard, had blazed a vermilion trail along the
+Great White Way, but his sister was of the opposite temperament,
+interested in social work, and had attracted much attention by
+organizing a settlement in the slums of Stratfield for the uplift
+of the workers in the Pearcy and other mills.
+
+Broadway, as well as Stratfield, had already woven a fantastic
+background, for the mystery and hints had been broadly made that
+Annette Oakleigh had been indiscreetly intimate with a young
+physician in the town, a Dr. Gunther, a friend, by the way, of
+Minturn. "There has been no trial yet," went on Kennedy, "but
+Minturn seems to have appeared before the coroner's jury at
+Stratfield and to have asserted the innocence of Mrs. Pearcy and
+that of Dr. Gunther so well that, although the jury brought in a
+verdict of murder by poison by some one unknown, there has been no
+mention of the name of anyone else. The coroner simply adjourned
+the inquest so that a more careful analysis might be made of the
+vital organs. And now comes this second tragedy in New York."
+
+"What was the poison?" I asked. "Have they found out yet?"
+
+"They are pretty sure, so Minturn told me, that it was lead
+poisoning. The fact not generally known is," he added in a lower
+tone, "that the cases were not confined to the Pearcy house. They
+had even extended to Minturn's too, although about that he said
+little yesterday. The estates up there adjoin, you know."
+
+Owen Minturn, I recalled, had gained a formidable reputation by
+his successful handling of cases from the lowest strata of society
+to the highest. Indeed it was a byword that his appearance in
+court indicated two things--the guilt of the accused and a verdict
+of acquittal.
+
+"Of course," Craig pursued as we were jolted from station to
+station downtown, "you know they say that Minturn never kept a
+record of a case. But written records were as nothing compared to
+what that man must have carried only in his head."
+
+It was a common saying that, if Minturn should tell all he knew,
+he might hang half a dozen prominent men in society. That was not
+strictly true, perhaps, but it was certain that a revelation of
+the things confided to him by clients which were never put down on
+paper would have caused a series of explosions that would have
+wrecked at least some portions of the social and financial world.
+He had heard much and told little, for he had been a sort of
+"father confessor."
+
+Had Minturn, I wondered, known the name of the real criminal?
+
+Josephson's was a popular bath on Forty-second Street, where many
+of the "sun-dodgers" were accustomed to recuperate during the day
+from their arduous pursuit of pleasure at night and prepare for
+the resumption of their toil during the coming night. It was more
+than that, however, for it had a reputation for being conducted
+really on a high plane.
+
+We met Josephson downstairs. He had been released under bail,
+though the place was temporarily closed and watched over by the
+agents of the coroner and the police. Josephson appeared to be a
+man of some education and quite different from what I had imagined
+from hearing him over the telephone.
+
+"Oh, Mr. Kennedy," he exclaimed, "who now will come to my baths?
+Last night they were crowded, but to-day--"
+
+He ended with an expressive gesture of his hands.
+
+"One customer I have surely lost, young Mr. Pearcy," he went on.
+
+"Warner Pearcy?" asked Craig. "Was he here last night?"
+
+"Nearly every night," replied Josephson, now glib enough as his
+first excitement subsided and his command of English returned. "He
+was a neighbor of Mr. Minturn's, I hear. Oh, what luck!" growled
+Josephson as the name recalled him to his present troubles.
+
+"Well," remarked Kennedy with an attempt at reassurance as if to
+gain the masseur's confidence, "I know as well as you that it is
+often amazing what a tremendous shock a man may receive and yet
+not be killed, and no less amazing how small a shock may kill. It
+all depends on circumstances."
+
+Josephson shot a covert look at Kennedy. "Yes," he reiterated,
+"but I cannot see how it COULD be. If the lights had become short-
+circuited with the bath, that might have thrown a current into the
+bath. But they were not. I know it."
+
+"Still," pursued Kennedy, watching him keenly, "it is not all a
+question of current. To kill, the shock must pass through a vital
+organ--the brain, the heart, the upper spinal cord. So, a small
+shock may kill and a large one may not. If it passes in one foot
+and out by the other, the current isn't likely to be as dangerous
+as if it passes in by a hand or foot and then out by a foot or
+hand. In one case it passes through no vital organ; in the other
+it is very likely to do so. You see, the current can flow through
+the body only when it has a place of entrance and a place of exit.
+In all cases of accident from electric light wires, the victim is
+touching some conductor--damp earth, salty earth, water, something
+that gives the current an outlet and--"
+
+"But even if the lights had been short-circuited," interrupted
+Josephson, "Mr. Minturn would have escaped injury unless he had
+touched the taps of the bath. Oh, no, sir, accidents in the
+medical use of electricity are rare. They don't happen here in my
+establishment," he maintained stoutly. "The trouble was that the
+coroner, without any knowledge of the physiological effects of
+electricity on the body, simply jumped at once to the conclusion
+that it was the electric bath that did it."
+
+"Then it was for medical treatment that Mr. Minturn was taking the
+bath?" asked Kennedy, quickly taking up the point.
+
+"Yes, of course," answered the masseur, eager to explain. "You are
+acquainted with the latest treatment for lead poisoning by means
+of the electric bath?"
+
+Kennedy nodded. "I know that Sir Thomas Oliver, the English
+authority who has written much on dangerous trades, has tried it
+with marked success."
+
+"Well, sir, that was why Mr. Minturn was here. He came here
+introduced by a Dr. Gunther of Stratfield."
+
+"Indeed?" remarked Kennedy colorlessly, though I could see that it
+interested him, for evidently Minturn had said nothing of being
+himself a sufferer from the poison. "May I see the bath?"
+
+"Surely," said Josephson, leading the way upstairs.
+
+It was an oaken tub with metal rods on the two long sides, from
+which depended prismatic carbon rods. Kennedy examined it closely.
+
+"This is what we call a hydro-electric bath," Josephson explained.
+"Those rods on the sides are the electrodes. You see there are no
+metal parts in the tub itself. The rods are attached by wiring to
+a wall switch out here."
+
+He pointed to the next room. Kennedy examined the switch with
+care.
+
+"From it," went on Josephson, "wires lead to an accumulator
+battery of perhaps thirty volts. It uses very little current. Dr.
+Gunther tested it and found it all right."
+
+Craig leaned over the bath, and from the carbon electrodes scraped
+off a white powder in minute crystals.
+
+"Ordinarily," Josephson pursued, "lead is eliminated by the skin
+and kidneys. But now, as you know, it is being helped along by
+electrolysis. I talked to Dr. Gunther about it. It is his opinion
+that it is probably eliminated as a chloride from the tissues of
+the body to the electrodes in the bath in which the patient is
+wholly or partly immersed. On the positive electrodes we get the
+peroxide. On the negative there is a spongy metallic form of lead.
+But it is only a small amount."
+
+"The body has been removed?" asked Craig.
+
+"Not yet," the masseur replied. "The coroner has ordered it kept
+here under guard until he makes up his mind what disposition to
+have made of it."
+
+We were next ushered into a little room on the same floor, at the
+door of which was posted an official from the coroner.
+
+"First of all," remarked Craig, as he drew back the sheet and
+began, a minute examination of the earthly remains of the great
+lawyer, "there are to be considered the safeguards of the human
+body against the passage through it of a fatal electric current--
+the high electric resistance of the body itself. It is
+particularly high when the current must pass through joints such
+as wrists, knees, elbows, and quite high when the bones of the
+head are concerned. Still, there might have been an incautious
+application of the current to the head, especially when the
+subject is a person of advanced age or latent cerebral disease,
+though I don't know that that fits Mr. Minturn. That's strange,"
+he muttered, looking up, puzzled. "I can find no mark of a burn on
+the body--absolutely no mark of anything."
+
+"That's what I say," put in Josephson, much pleased by what
+Kennedy said, for he had been waiting anxiously to see what Craig
+discovered on his own examination. "It's impossible."
+
+"It's all the more remarkable," went on Craig, half to himself and
+ignoring Josephson, "because burns due to electric currents are
+totally unlike those produced in other ways. They occur at the
+point of contact, usually about the arms and hands, or the head.
+Electricity is much to be feared when it involves the cranial
+cavity." He completed his examination of the head which once had
+carried secrets which themselves must have been incandescent.
+
+"Then, too, such burns are most often something more than
+superficial, for considerable heat is developed which leads to
+massive destruction and carbonization of the tissues to a
+considerable depth. I have seen actual losses of substance--a lump
+of killed flesh surrounded by healthy tissues. Besides, such burns
+show an unexpected indolence when compared to the violent pains of
+ordinary burns. Perhaps that is due to the destruction of the
+nerve endings. How did Minturn die? Was he alone? Was he dead when
+he was discovered?"
+
+"He was alone," replied Josephson, slowly endeavoring to tell it
+exactly as he had seen it, "but that's the strange part of it. He
+seemed to be suffering from a convulsion. I think he complained at
+first of a feeling of tightness of his throat and a twitching of
+the muscles of his hands and feet. Anyhow, he called for help. I
+was up here and we rushed in. Dr. Gunther had just brought him and
+then had gone away, after introducing him, and showing him the
+bath."
+
+Josephson proceeded slowly, evidently having been warned that
+anything he said might be used against him. "We carried him, when
+he was this way, into this very room. But it was only for a short
+time. Then came a violent convulsion. It seemed to extend rapidly
+all over his body. His legs were rigid, his feet bent, his head
+back. Why, he was resting only on his heels and the back of his
+head. You see, Mr. Kennedy, that simply could not be the electric
+shock."
+
+"Hardly," commented Kennedy, looking again at the body. "It looks
+more like a tetanus convulsion. Yet there does not seem to be any
+trace of a recent wound that might have caused lockjaw. How did he
+look?"
+
+"Oh, his face finally became livid," replied Josephson. "He had a
+ghastly, grinning expression, his eyes were wide, there was foam
+on his mouth, and his breathing was difficult."
+
+"Not like tetanus, either," revised Craig. "There the convulsion
+usually begins with the face and progresses to the other muscles.
+Here it seems to have gone the other way."
+
+"That lasted a minute or so," resumed the masseur. "Then he sank
+back--perfectly limp. I thought he was dead. But he was not. A
+cold sweat broke out all over him and he was as if in a deep
+sleep."
+
+"What did you do?" prompted Kennedy.
+
+"I didn't know what to do. I called an ambulance. But the moment
+the door opened, his body seemed to stiffen again. He had one
+other convulsion--and when he grew limp he was dead."
+
+
+
+
+CHAPTER XXIX
+
+THE LEAD POISONER
+
+
+It was a gruesome recital and I was glad to leave the baths
+finally with Kennedy. Josephson was quite evidently relieved at
+the attitude Craig had taken toward the coroner's conclusion that
+Minturn had been shocked to death. As far as I could see, however,
+it added to rather than cleared up the mystery.
+
+Craig went directly uptown to his laboratory, in contrast with our
+journey down, in abstracted silence, which was his manner when he
+was trying to reason out some particularly knotty problem.
+
+As Kennedy placed the white crystals which he had scraped off the
+electrodes of the tub on a piece of dark paper in the laboratory,
+he wet the tip of his finger and touched just the minutest grain
+to his tongue.
+
+The look on his face told me that something unexpected had
+happened. He held a similar minute speck of the powder out to me.
+
+It was an intensely bitter taste and very persistent, for even
+after we had rinsed out our mouths it seemed to remain, clinging
+persistently to the tongue.
+
+He placed some of the grains in some pure water. They dissolved
+only slightly, if at all. But in a tube in which he mixed a little
+ether and chloroform they dissolved fairly readily.
+
+Next, without a word, he poured just a drop of strong sulphuric
+acid on the crystals. There was not a change in them.
+
+Quickly he reached up into the rack and took down a bottle labeled
+"Potassium Bichromate."
+
+"Let us see what an oxidizing agent will do," he remarked.
+
+As he gently added the bichromate, there came a most marvelous,
+kaleidoscopic change. From being almost colorless, the crystals
+turned instantly to a deep blue, then rapidly to purple, lilac,
+red, and then the red slowly faded away and they became colorless
+again.
+
+"What is it?" I asked, fascinated. "Lead?"
+
+"N-no," he replied, the lines of his forehead deepening. "No. This
+is sulphate of strychnine."
+
+"Sulphate of strychnine?" I repeated in astonishment.
+
+"Yes," he reiterated slowly. "I might have suspected that from the
+convulsions, particularly when Josephson said that the noise and
+excitement of the arrival of the ambulance brought on the fatal
+paroxysm. That is symptomatic. But I didn't fully realize it until
+I got up here and tasted the stuff. Then I suspected, for that
+taste is characteristic. Even one part diluted seventy thousand
+times gives that decided bitter taste."
+
+"That's all very well," I remarked, recalling the intense
+bitterness yet on my tongue. "But how do you suppose it was
+possible for anyone to administer it? It seems to me that he would
+have said something, if he had swallowed even the minutest part of
+it. He must have known it. Yet apparently he didn't. At least he
+said nothing about it--or else Josephson is concealing something."
+
+"Did he swallow it--necessarily?" queried Kennedy, in a tone
+calculated to show me that the chemical world, at least, was full
+of a number of things, and there was much to learn.
+
+"Well, I suppose if it had been given hypodermically, it would
+have a more violent effect," I persisted, trying to figure out a
+way that the poison might have been given.
+
+"Even more unlikely," objected Craig, with a delight at
+discovering a new mystery that to me seemed almost fiendish. "No,
+he would certainly have felt a needle, have cried out and said
+something about it, if anyone had tried that. This poisoned needle
+business isn't as easy as some people seem to think nowadays."
+
+"Then he might have absorbed it from the water," I insisted,
+recalling a recent case of Kennedy's and adding, "by osmosis."
+
+"You saw how difficult it was to dissolve in water," Craig
+rejected quietly.
+
+"Well, then," I concluded in desperation. "How could it have been
+introduced?"
+
+"I have a theory," was all he would say, reaching for the railway
+guide, "but it will take me up to Stratfield to prove it."
+
+His plan gave us a little respite and we paused long enough to
+lunch, for which breathing space I was duly thankful. The forenoon
+saw us on the train, Kennedy carrying a large and cumbersome
+package which he brought down with him from the laboratory and
+which we took turns in carrying, though he gave no hint of its
+contents.
+
+We arrived in Stratfield, a very pretty little mill town, in the
+middle of the afternoon, and with very little trouble were
+directed to the Pearcy house, after Kennedy had checked the parcel
+with the station agent.
+
+Mrs. Pearcy, to whom we introduced ourselves as reporters of the
+Star, was a tall blonde. I could not help thinking that she made a
+particularly dashing widow. With her at the time was Isabel
+Pearcy, a slender girl whose sensitive lips and large, earnest
+eyes indicated a fine, high-strung nature.
+
+Even before we had introduced ourselves, I could not help thinking
+that there was a sort of hostility between the women. Certainly it
+was evident that there was as much difference in temperament as
+between the butterfly and the bee.
+
+"No," replied the elder woman quickly to a request from Kennedy
+for an interview, "there is nothing that I care to say to the
+newspapers. They have said too much already about this--
+unfortunate affair."
+
+Whether it was imagination or not, I fancied that there was an air
+of reserve about both women. It struck me as a most peculiar
+household. What was it? Was each suspicious of the other? Was each
+concealing something?
+
+I managed to steal a glance at Kennedy's face to see whether there
+was anything to confirm my own impression. He was watching Mrs.
+Pearcy closely as she spoke. In fact his next few questions,
+inconsequential as they were, seemed addressed to her solely for
+the purpose of getting her to speak.
+
+I followed his eyes and found that he was watching her mouth, in
+reality. As she answered I noted her beautiful white teeth.
+Kennedy himself had trained me to notice small things, and at the
+time, though I thought it was trivial, I recall noticing on her
+gums, where they joined the teeth, a peculiar bluish-black line.
+
+Kennedy had been careful to address only Mrs. Pearcy at first, and
+as he continued questioning her, she seemed to realize that he was
+trying to lead her along.
+
+"I must positively refuse to talk any more," she repeated finally,
+rising. "I am not to be tricked into saying anything."
+
+She had left the room, evidently expecting that Isabel would
+follow. She did not. In fact I felt that Miss Pearcy was visibly
+relieved by the departure of her stepmother. She seemed anxious to
+ask us something and now took the first opportunity.
+
+"Tell me," she said eagerly, "how did Mr. Minturn die? What do
+they really think of it in New York?"
+
+"They think it is poisoning," replied Craig, noting the look on
+her face.
+
+She betrayed nothing, as far as I could see, except a natural
+neighborly interest. "Poisoning?" she repeated. "By what?"
+
+"Lead poisoning," he replied evasively.
+
+She said nothing. It was evident that, slip of a girl though she
+was, she was quite the match of anyone who attempted leading
+questions. Kennedy changed his method.
+
+"You will pardon me," he said apologetically, "for recalling what
+must be distressing. But we newspapermen often have to do things
+and ask questions that are distasteful. I believe it is rumored
+that your father suffered from lead poisoning?"
+
+"Oh, I don't know what it was--none of us do," she cried, almost
+pathetically. "I had been living at the settlement until lately.
+When father grew worse, I came home. He had such strange visions--
+hallucinations, I suppose you would call them. In the daytime he
+would be so very morose and melancholy. Then, too, there were
+terrible pains in his stomach, and his eyesight began to fail.
+Yes, I believe that Dr. Gunther did say it was lead poisoning.
+But--they have said so many things--so many things," she repeated,
+plainly distressed at the subject of her recent bereavement.
+
+"Your brother is not at home?" asked Kennedy, quickly changing the
+subject.
+
+"No," she answered, then with a flash as though lifting the veil
+of a confidence, added: "You know, neither Warner nor I have lived
+here much this year. He has been in New York most of the time and
+I have been at the settlement, as I already told you."
+
+She hesitated, as if wondering whether she should say more, then
+added quickly: "It has been repeated often enough; there is no
+reason why I shouldn't say it to you. Neither of us exactly
+approved of father's marriage."
+
+She checked herself and glanced about, somewhat with the air of
+one who has suddenly considered the possibility of being
+overheard.
+
+"May I have a glass of water?" asked Kennedy suddenly.
+
+"Why, certainly," she answered, going to the door, apparently
+eager for an excuse to find out whether there was some one on the
+other side of it.
+
+There was not, nor any indication that there had been.
+
+"Evidently she does not have any suspicions of THAT," remarked
+Kennedy in an undertone, half to himself.
+
+I had no chance to question him, for she returned almost
+immediately. Instead of drinking the water, however, he held it
+carefully up to the light. It was slightly turbid.
+
+"You drink the water from the tap?" he asked, as he poured some of
+it into a sterilized vial which he drew quickly from his vest
+pocket.
+
+"Certainly," she replied, for the moment nonplussed at his strange
+actions. "Everybody drinks the town water in Stratfield."
+
+A few more questions, none of which were of importance, and
+Kennedy and I excused ourselves.
+
+At the gate, instead of turning toward the town, however, Kennedy
+went on and entered the grounds of the Minturn house next door.
+The lawyer, I had understood, was a widower and, though he lived
+in Stratfield only part of the time, still maintained his house
+there.
+
+We rang the bell and a middle-aged housekeeper answered.
+
+"I am from the water company," he began politely. "We are testing
+the water, perhaps will supply consumers with filters. Can you let
+me have a sample?"
+
+She did not demur, but invited us in. As she drew the water, Craig
+watched her hands closely. She seemed to have difficulty in
+holding the glass, and as she handed it to him, I noticed a
+peculiar hanging down of the wrist. Kennedy poured the sample into
+a second vial, and I noticed that it was turbid, too. With no
+mention of the tragedy to her employer, he excused himself, and we
+walked slowly back to the road.
+
+Between the two houses Kennedy paused, and for several moments
+appeared to be studying them.
+
+We walked slowly back along the road to the town. As we passed the
+local drug store, Kennedy turned and sauntered in.
+
+He found it easy enough to get into conversation with the
+druggist, after making a small purchase, and in the course of a
+few minutes we found ourselves gossiping behind the partition that
+shut off the arcana of the prescription counter from the rest of
+the store.
+
+Gradually Kennedy led the conversation around to the point which
+he wanted, and asked, "I wish you'd let me fix up a little
+sulphureted hydrogen."
+
+"Go ahead," granted the druggist good-naturedly. "I guess you can
+do it. You know as much about drugs as I do. I can stand the
+smell, if you can."
+
+Kennedy smiled and set to work.
+
+Slowly he passed the gas through the samples of water he had taken
+from the two houses. As he did so the gas, bubbling through, made
+a blackish precipitate.
+
+"What is it?" asked the druggist curiously.
+
+"Lead sulphide," replied Kennedy, stroking his chin. "This is an
+extremely delicate test. Why, one can get a distinct brownish
+tinge if lead is present in even incredibly minute quantities."
+
+He continued to work over the vials ranged on the table before
+him.
+
+"The water contains, I should say, from ten to fifteen hundredths
+of a grain of lead to the gallon," he remarked finally.
+
+"Where did it come from?" asked the druggist, unable longer to
+restrain his curiosity.
+
+"I got it up at Pearcy's," Kennedy replied frankly, turning to
+observe whether the druggist might betray any knowledge of it.
+
+"That's strange," he replied in genuine surprise. "Our water in
+Stratfield is supplied by a company to a large area, and it has
+always seemed to me to be of great organic purity."
+
+"But the pipes are of lead, are they not?" asked Kennedy.
+
+"Y-yes," answered the druggist, "I think in most places the
+service pipes are of lead. But," he added earnestly as he saw the
+implication of his admission, "water has never to my knowledge
+been found to attack the pipes so as to affect its quality
+injuriously."
+
+He turned his own faucet and drew a glassful. "It is normally
+quite clear," he added, holding the glass up.
+
+It was in fact perfectly clear, and when he passed some of the gas
+through it nothing happened at all.
+
+Just then a man lounged into the store.
+
+"Hello, Doctor," greeted the druggist. "Here are a couple of
+fellows that have been investigating the water up at Pearcy's.
+They've found lead in it. That ought to interest you. This is Dr.
+Gunther," he introduced, turning to us.
+
+It was an unexpected encounter, one I imagine that Kennedy might
+have preferred to take place under other circumstances. But he was
+equal to the occasion.
+
+"We've been sent up here to look into the case for the New York
+Star," Kennedy said quickly. "I intended to come around to see
+you, but you have saved me the trouble."
+
+Dr. Gunther looked from one of us to the other. "Seems to me the
+New York papers ought to have enough to do without sending men all
+over the country making news," he grunted.
+
+"Well," drawled Kennedy quietly, "there seems to be a most
+remarkable situation up there at Pearcy's and Minturn's, too. As
+nearly as I can make out several people there are suffering from
+unmistakable signs of lead poisoning. There are the pains in the
+stomach, the colic, and then on the gums is that characteristic
+line of plumbic sulphide, the distinctive mark produced by lead.
+There is the wrist-drop, the eyesight affected, the partial
+paralysis, the hallucinations and a condition in old Pearcy's case
+almost bordering on insanity--to enumerate the symptoms that seem
+to be present in varying degrees in various persons in the two
+houses."
+
+Gunther looked at Kennedy, as if in doubt just how to take him.
+
+"That's what the coroner says, too--lead poisoning," put in the
+druggist, himself as keen as anyone else for a piece of local
+news, and evidently not averse to stimulating talk from Dr.
+Gunther, who had been Pearcy's physician.
+
+"That all seems to be true enough," replied Gunther at length
+guardedly. "I recognized that some time ago."
+
+"Why do you think it affects each so differently?" asked the
+druggist.
+
+Dr. Gunther settled himself easily back in a chair to speak as one
+having authority. "Well," he began slowly, "Miss Pearcy, of
+course, hasn't been living there much until lately. As for the
+others, perhaps this gentleman here from the Star knows that lead,
+once absorbed, may remain latent in the system and then make
+itself felt. It is like arsenic, an accumulative poison, slowly
+collecting in the body until the limit is reached, or until the
+body, becoming weakened from some other cause, gives way to it."
+
+He shifted his position slowly, and went on, as if defending the
+course of action he had taken in the case.
+
+"Then, too, you know, there is an individual as well as family and
+sex susceptibility to lead. Women are especially liable to lead
+poisoning, but then perhaps in this case Mrs. Pearcy comes of a
+family that is very resistant. There are many factors. Personally,
+I don't think Pearcy himself was resistant. Perhaps Minturn was
+not, either. At any rate, after Pearcy's death, it was I who
+advised Minturn to take the electrolysis cure in New York. I took
+him down there," added Gunther. "Confound it, I wish I had stayed
+with him. But I always found Josephson perfectly reliable in
+hydrotherapy with other patients I sent to him, and I understood
+that he had been very successful with cases sent to him by many
+physicians in the city." He paused and I waited anxiously to see
+whether Kennedy would make some reference to the discovery of the
+strychnine salts.
+
+"Have you any idea how the lead poisoning could have been caused?"
+asked Kennedy instead.
+
+Dr. Gunther shook his head. "It is a puzzle to me," he answered.
+"I am sure of only one thing. It could not be from working in
+lead, for it is needless to say that none of them worked."
+
+"Food?" Craig suggested.
+
+The doctor considered. "I had thought of that. I know that many
+cases of lead poisoning have been traced to the presence of the
+stuff in ordinary foods, drugs and drinks. I have examined the
+foods, especially the bread. They don't use canned goods. I even
+went so far as to examine the kitchen ware to see if there could
+be anything wrong with the glazing. They don't drink wines and
+beers, into which now and then the stuff seems to get."
+
+"You seem to have a good grasp of the subject," flattered Kennedy,
+as we rose to go. "I can hardly blame you for neglecting the
+water, since everyone here seems to be so sure of the purity of
+the supply."
+
+Gunther said nothing. I was not surprised, for, at the very least,
+no one likes to have an outsider come in and put his finger
+directly on the raw spot. What more there might be to it, I could
+only conjecture.
+
+We left the druggist's and Kennedy, glancing at his watch,
+remarked: "If you will go down to the station, Walter, and get
+that package we left there, I shall be much obliged to you. I want
+to make just one more stop, at the office of the water company,
+and I think I shall just about have time for it. There's a pretty
+good restaurant across the street. Meet me there, and by that time
+I shall know whether to carry out a little plan I have outlined or
+not."
+
+
+
+
+CHAPTER XXX
+
+THE ELECTROLYTIC MURDER
+
+
+We dined leisurely, which seemed strange to me, for it was not
+Kennedy's custom to let moments fly uselessly when he was on a
+case. However, I soon found out why it was. He was waiting for
+darkness.
+
+As soon as the lights began to glow in the little stores on the
+main street, we sallied forth, taking the direction of the Pearcy
+and Minturn houses.
+
+On the way he dropped into the hardware store and purchased a
+light spade and one of the small pocket electric flashlights,
+about which he wrapped a piece of cardboard in such a way as to
+make a most effective dark lantern.
+
+We trudged along in silence, occasionally changing from carrying
+the heavy package to the light spade.
+
+Both the Pearcy and Minturn houses were in nearly total darkness
+when we arrived. They set well back from the road and were
+plentifully shielded by shrubbery. Then, too, at night it was not
+a much frequented neighborhood. We could easily hear the footsteps
+of anyone approaching on the walk, and an occasional automobile
+gliding past did not worry us in the least.
+
+"I have calculated carefully from an examination of the water
+company's map," said Craig, "just where the water pipe of the two
+houses branches off from the main in the road."
+
+After a measurement or two from some landmark, we set to work a
+few feet inside, under cover of the bushes and the shadows, like
+two grave diggers.
+
+Kennedy had been wielding the spade vigorously for a few minutes
+when it touched something metallic. There, just beneath the frost
+line, we came upon the service pipe.
+
+He widened the hole, and carefully scraped off the damp earth that
+adhered to the pipe. Next he found a valve where he shut off the
+water and cut out a small piece of the pipe.
+
+"I hope they don't suspect anything like this in the houses with
+their water cut off," he remarked as he carefully split the piece
+open lengthwise and examined it under the light.
+
+On the interior of the pipe could be seen patchy lumps of white
+which projected about an eighth of an inch above the internal
+surface. As the pipe dried in the warm night air, they could
+easily be brushed off as a white powder.
+
+"What is it--strychnine?" I asked.
+
+"No," he replied, regarding it thoughtfully with some
+satisfaction. "That is lead carbonate. There can be no doubt that
+the turbidity of the water was due to this powder in suspension. A
+little dissolves in the water, while the scales and incrustations
+in fine particles are carried along in the current. As a matter of
+fact the amount necessary to make the water poisonous need not be
+large."
+
+He applied a little instrument to the cut ends of the pipe. As I
+bent over, I could see the needle on its dial deflected just a
+bit.
+
+"My voltmeter," he said, reading it, "shows that there is a
+current of about 1.8 volts passing through this pipe all the
+time."
+
+"Electrolysis of water pipes!" I exclaimed, thinking of statements
+I had heard by engineers. "That's what they mean by stray or
+vagabond currents, isn't it?"
+
+He had seized the lantern and was eagerly following up and down
+the line of the water pipe. At last he stopped, with a low
+exclamation, at a point where an electric light wire supplying the
+Minturn cottage crossed overhead. Fastened inconspicuously to the
+trunk of a tree which served as a support for the wire was another
+wire which led down from it and was buried in the ground.
+
+Craig turned up the soft earth as fast as he could, until he
+reached the pipe at this point. There was the buried wire wound
+several times around it.
+
+As quickly and as neatly as he could he inserted a connection
+between the severed ends of the pipe to restore the flow of water
+to the houses, turned on the water and covered up the holes he had
+dug. Then he unwrapped the package which we had tugged about all
+day, and in a narrow path between the bushes which led to the
+point where the wire had tapped the electric light feed he placed
+in a shallow hole in the ground a peculiar apparatus.
+
+As nearly as I could make it out, it consisted of two flat
+platforms between which, covered over and projected, was a slip of
+paper which moved forward, actuated by clockwork, and pressed on
+by a sort of stylus. Then he covered it over lightly with dirt so
+that, unless anyone had been looking for it, it would never be
+noticed.
+
+It was late when we reached the city again, but Kennedy had one
+more piece of work and that devolved on me. All the way down on
+the train he had been writing and rewriting something.
+
+"Walter," he said, as the train pulled into the station, "I want
+that published in to-morrow's papers."
+
+I looked over what he had written. It was one of the most
+sensational stories I have ever fathered, beginning, "Latest of
+the victims of the unknown poisoner of whole families in
+Stratfield, Connecticut, is Miss Isabel Pearcy, whose father,
+Randall Pearcy, died last week."
+
+I knew that it was a "plant" of some kind, for so far he had
+discovered no evidence that Miss Pearcy had been affected. What
+his purpose was, I could not guess, but I got the story printed.
+
+The next morning early Kennedy was quietly at work in the
+laboratory.
+
+"What is this treatment of lead poisoning by electrolysis?" I
+asked, now that there had come a lull when I might get an
+intelligible answer. "How does it work?"
+
+"Brand new, Walter," replied Kennedy. "It has been discovered that
+ions will flow directly through the membranes."
+
+"Ions?" I repeated. "What are ions?"
+
+"Travelers," he answered, smiling, "so named by Faraday from the
+Greek verb, io, to go. They are little positive and negative
+charges of electricity of which molecules are composed. You know
+some believe now that matter is really composed of electrical
+energy. I think I can explain it best by a simile I use with my
+classes. It is as though you had a ballroom in which the dancers
+in couples represent the neutral molecules. There are a certain
+number of isolated ladies and gentlemen--dissociated ions--" "Who
+don't know these new dances?" I interrupted.
+
+"They all know this dance," he laughed. "But, to be serious in the
+simile, suppose at one end of the room there is a large mirror and
+at the other a buffet with cigars and champagne. What happens to
+the dissociated ions?"
+
+"Well, I suppose you want me to say that the ladies gather about
+the mirror and the men about the buffet."
+
+"Exactly. And some of the dancing partners separate and follow the
+crowd. Well, that room presents a picture of what happens in an
+electrolytic solution at the moment when the electric current is
+passing through it."
+
+"Thanks," I laughed. "That was quite adequate to my immature
+understanding."
+
+Kennedy continued at work, checking up and arranging his data
+until the middle of the afternoon, when he went up to Stratfield.
+
+Having nothing better to do, I wandered out about town in the hope
+of running across some one with whom to while away the hours until
+Kennedy returned. I found out that, since yesterday, Broadway had
+woven an entirely new background for the mystery. Now it was
+rumored that the lawyer Minturn himself had been on very intimate
+terms with Mrs. Pearcy. I did not pay much attention to the rumor,
+for I knew that Broadway is constitutionally unable to believe
+that anybody is straight.
+
+Kennedy had commissioned me to keep in touch with Josephson and I
+finally managed to get around to the Baths, to find them still
+closed.
+
+As I was talking with him, a very muddy and dusty car pulled up at
+the door and a young man whose face was marred by the red
+congested blood vessels that are in some a mark of dissipation
+burst in on us.
+
+"What--closed up yet--Joe?" he asked. "Haven't they taken
+Minturn's body away?"
+
+"Yes, it was sent up to Stratfield to-day," replied the masseur,
+"but the coroner seems to want to worry me all he can."
+
+"Too bad. I was up almost all last night, and to-day I have been
+out in my car--tired to death. Thought I might get some rest here.
+Where are you sending the boys--to the Longacre?"
+
+"Yes. They'll take good care of you till I open up again. Hope to
+see you back again, then, Mr. Pearcy," he added, as the young man
+turned and hurried out to his car again. "That was that young
+Pearcy, you know. Nice boy--but living the life too fast. What's
+Kennedy doing--anything?"
+
+I did not like the jaunty bravado of the masseur which now seemed
+to be returning, since nothing definite had taken shape. I
+determined that he should not pump me, as he evidently was trying
+to do. I had at least fulfilled Kennedy's commission and felt that
+the sooner I left Josephson the better for both of us.
+
+I was surprised at dinner to receive a wire from Craig saying that
+he was bringing down Dr. Gunther, Mrs. Pearcy and Isabel to New
+York and asking me to have Warner Pearcy and Josephson at the
+laboratory at nine o'clock.
+
+By strategy I managed to persuade Pearcy to come, and as for
+Josephson, he could not very well escape, though I saw that as
+long as nothing more had happened, he was more interested in
+"fixing" the police so that he could resume business than anything
+else.
+
+As we entered the laboratory that night, Kennedy, who had left his
+party at a downtown hotel to freshen up, met us each at the door.
+Instead of conducting us in front of his laboratory table, which
+was the natural way, he led us singly around through the narrow
+space back of it.
+
+I recall that as I followed him, I half imagined that the floor
+gave way just a bit, and there flashed over me, by a queer
+association of ideas, the recollection of having visited an
+amusement park not long before where merely stepping on an
+innocent-looking section of the flooring had resulted in a
+tremendous knocking and banging beneath, much to the delight of
+the lovers of slap-stick humor. This was serious business,
+however, and I quickly banished the frivolous thought from my
+mind.
+
+"The discovery of poison, and its identification," began Craig at
+last when we had all arrived and were seated about him, "often
+involves not only the use of chemistry but also a knowledge of the
+chemical effect of the poison on the body, and the gross as well
+as microscopic changes which it produces in various tissues and
+organs--changes, some due to mere contact, others to the actual
+chemicophysiological reaction between the poison and the body."
+
+His hand was resting on the poles of a large battery, as he
+proceeded: "Every day the medical detective plays a more and more
+important part in the detection of crime, and I might say that,
+except in the case of crime complicated by a lunacy plea, his work
+has earned the respect of the courts and of detectives, while in
+the case of insanity the discredit is the fault rather of the law
+itself. The ways in which the doctor can be of use in untangling
+the facts in many forms of crime have become so numerous that the
+profession of medical detective may almost be called a specialty."
+
+Kennedy repeated what he had already told me about electrolysis,
+then placed between the poles of the battery a large piece of raw
+beef.
+
+He covered the negative electrode with blotting paper and soaked
+it in a beaker near at hand.
+
+"This solution," he explained, "is composed of potassium iodide.
+In this other beaker I have a mixture of ordinary starch."
+
+He soaked the positive electrode in the starch and then jammed the
+two against the soft red meat. Then he applied the current.
+
+A few moments later he withdrew the positive electrode. Both it
+and the meat under it were blue!
+
+"What has happened?" he asked. "The iodine ions have actually
+passed through the beef to the positive pole and the paper on the
+electrode. Here we have starch iodide."
+
+It was a startling idea, this of the introduction of a substance
+by electrolysis.
+
+"I may say," he resumed, "that the medical view of electricity is
+changing, due in large measure to the genius of the Frenchman, Dr.
+Leduc. The body, we know, is composed largely of water, with salts
+of soda and potash. It is an excellent electrolyte. Yet most
+doctors regard the introduction of substances by the electric
+current as insignificant or nonexistent. But on the contrary the
+introduction of drugs by electrolysis is regular and far from
+being insignificant may very easily bring about death.
+
+"That action," he went on, looking from one of us to another, "may
+be therapeutic, as in the cure for lead poisoning by removing the
+lead, or it may be toxic--as in the case of actually introducing
+such a poison as strychnine into the body by the same forces that
+will remove the lead."
+
+He paused a moment, to enforce the point which had already been
+suggested. I glanced about hastily. If anyone in his little
+audience was guilty, no one betrayed it, for all were following
+him, fascinated. Yet in the wildly throbbing brain of some one of
+them the guilty knowledge must be seared indelibly. Would the mere
+accusation be enough to dissociate the truth from, that brain or
+would Kennedy have to resort to other means?
+
+"Some one," he went on, in a low, tense voice, leaning forward,
+"some one who knew this effect placed strychnine salts on one of
+the electrodes of the bath which Owen Minturn was to use."
+
+He did not pause. Evidently he was planning to let the force of
+his exposure be cumulative, until from its sheer momentum it
+carried everything before it.
+
+"Walter," he ordered quickly. "Lend me a hand."
+
+Together we moved the laboratory table as he directed.
+
+There, in the floor, concealed by the shadow, he had placed the
+same apparatus which I had seen him bury in the path between the
+Pearcy and Minturn estates at Stratfield.
+
+We scarcely breathed.
+
+"This," he explained rapidly, "is what is known as a kinograph--
+the invention of Professor HeleShaw of London. It enables me to
+identify a person by his or her walk. Each of you as you entered
+this room has passed over this apparatus and has left a different
+mark on the paper which registers."
+
+For a moment he stopped, as if gathering strength for the final
+assault.
+
+"Until late this afternoon I had this kinograph secreted at a
+certain place in Stratfield. Some one had tampered with the leaden
+water pipes and the electric light cable. Fearful that the lead
+poisoning brought on by electrolysis might not produce its result
+in the intended victim, that person took advantage of the new
+discoveries in electrolysis to complete that work by introducing
+the deadly strychnine during the very process of cure of the lead
+poisoning."
+
+He slapped down a copy of a newspaper. "In the news this morning I
+told just enough of what I had discovered and colored it in such a
+way that I was sure I would arouse apprehension. I did it because
+I wanted to make the criminal revisit the real scene of the crime.
+There was a double motive now--to remove the evidence and to check
+the spread of the poisoning."
+
+He reached over, tore off the paper with a quick, decisive motion,
+and laid it beside another strip, a little discolored by moisture,
+as though the damp earth had touched it.
+
+"That person, alarmed lest something in the cleverly laid plot,
+might be discovered, went to a certain spot to remove the traces
+of the diabolical work which were hidden there. My kinograph shows
+the footsteps, shows as plainly as if I had been present, the
+exact person who tried to obliterate the evidence,"
+
+An ashen pallor seemed to spread over the face of Miss Pearcy, as
+Kennedy shot out the words.
+
+"That person," he emphasized, "had planned to put out of the way
+one who had brought disgrace on the Pearcy family. It was an act
+of private justice."
+
+Mrs. Pearcy could stand the strain no longer. She had broken down
+and was weeping incoherently. I strained my ears to catch what she
+was murmuring. It was Minturn's name, not Gunther's, that was on
+her lips.
+
+"But," cried Kennedy, raising an accusatory finger from the
+kinograph tracing and pointing it like the finger of Fate itself,
+"but the self-appointed avenger forgot that the leaden water pipe
+was common to the two houses. Old Mr. Pearcy, the wronged, died
+first. Isabel has guessed the family skeleton--has tried hard to
+shield you, but, Warner Pearcy, you are the murderer!"
+
+
+
+
+CHAPTER XXXI
+
+THE EUGENIC BRIDE
+
+
+Scandal, such as that which Kennedy unearthed in this Pearcy case,
+was never much to his liking, yet he seemed destined, about this
+period of his career, to have a good deal of it.
+
+We had scarcely finished with the indictment that followed the
+arrest of young Pearcy, when we were confronted by a situation
+which was as unique as it was intensely modern.
+
+"There's absolutely no insanity in Eugenia's family," I heard a
+young man remark to Kennedy, as my key turned in the lock of the
+laboratory door.
+
+For a moment I hesitated about breaking in on a confidential
+conference, then reflected that, as they had probably already
+heard me at the lock, I had better go in and excuse myself.
+
+As I swung the door open, I saw a young man pacing up and down the
+laboratory nervously, too preoccupied even to notice the slight
+noise I had made.
+
+He paused in his nervous walk and faced Kennedy, his back to me.
+
+"Kennedy," he said huskily, "I wouldn't care if there was insanity
+in her family--for, my God!--the tragedy of it all now--I love
+her!"
+
+He turned, following Kennedy's eyes in my direction, and I saw on
+his face the most haggard, haunting look of anxiety that I had
+ever seen on a young person.
+
+Instantly I recognized from the pictures I had seen in the
+newspapers young Quincy Atherton, the last of this famous line of
+the family, who had attracted a great deal of attention several
+months previously by what the newspapers had called his search
+through society for a "eugenics bride," to infuse new blood into
+the Atherton stock.
+
+"You need have no fear that Mr. Jameson will be like the other
+newspaper men," reassured Craig, as he introduced us, mindful of
+the prejudice which the unpleasant notoriety of Atherton's
+marriage had already engendered in his mind.
+
+I recalled that when I had first heard of Atherton's "eugenic
+marriage," I had instinctively felt a prejudice against the very
+idea of such cold, calculating, materialistic, scientific mating,
+as if one of the last fixed points were disappearing in the chaos
+of the social and sex upheaval.
+
+Now, I saw that one great fact of life must always remain. We
+might ride in hydroaeroplanes, delve into the very soul by
+psychanalysis, perhaps even run our machines by the internal
+forces of radium--even marry according to Galton or Mendel. But
+there would always be love, deep passionate love of the man for
+the woman, love which all the discoveries of science might perhaps
+direct a little less blindly, but the consuming flame of which not
+all the coldness of science could ever quench. No tampering with
+the roots of human nature could ever change the roots.
+
+I must say that I rather liked young Atherton. He had a frank,
+open face, the most prominent feature of which was his somewhat
+aristocratic nose. Otherwise he impressed one as being the victim
+of heredity in faults, if at all serious, against which he was
+struggling heroically.
+
+It was a most pathetic story which he told, a story of how his
+family had degenerated from the strong stock of his ancestors
+until he was the last of the line. He told of his education, how
+he had fallen, a rather wild youth bent in the footsteps of his
+father who had been a notoriously good clubfellow, under the
+influence of a college professor, Dr. Crafts, a classmate of his
+father's, of how the professor had carefully and persistently
+fostered in him an idea that had completely changed him.
+
+"Crafts always said it was a case of eugenics against euthenics,"
+remarked Atherton, "of birth against environment. He would tell me
+over and over that birth gave me the clay, and it wasn't such bad
+clay after all, but that environment would shape the vessel."
+
+Then Atherton launched into a description of how he had striven to
+find a girl who had the strong qualities his family germ plasm
+seemed to have lost, mainly, I gathered, resistance to a taint
+much like manic depressive insanity. And as he talked, it was
+borne in on me that, after all, contrary to my first prejudice,
+there was nothing very romantic indeed about disregarding the
+plain teachings of science on the subject of marriage and one's
+children.
+
+In his search for a bride, Dr. Crafts, who had founded a sort of
+Eugenics Bureau, had come to advise him. Others may have looked up
+their brides in Bradstreet's, or at least the Social Register.
+Atherton had gone higher, had been overjoyed to find that a girl
+he had met in the West, Eugenia Gilman, measured up to what his
+friend told him were the latest teachings of science. He had been
+overjoyed because, long before Crafts had told him, he had found
+out that he loved her deeply.
+
+"And now," he went on, half choking with emotion, "she is
+apparently suffering from just the same sort of depression as I
+myself might suffer from if the recessive trait became active."
+
+"What do you mean, for instance?" asked Craig.
+
+"Well, for one thing, she has the delusion that my relatives are
+persecuting her."
+
+"Persecuting her?" repeated Craig, stifling the remark that that
+was not in itself a new thing in this or any other family. "How?"
+
+"Oh, making her feel that, after all, it is Atherton family rather
+than Gilman health that counts--little remarks that when our baby
+is born, they hope it will resemble Quincy rather than Eugenia,
+and all that sort of thing, only worse and more cutting, until the
+thing has begun to prey on her mind."
+
+"I see," remarked Kennedy thoughtfully. "But don't you think this
+is a case for a--a doctor, rather than a detective?"
+
+Atherton glanced up quickly. "Kennedy," he answered slowly, "where
+millions of dollars are involved, no one can guess to what lengths
+the human mind will go--no one, except you."
+
+"Then you have suspicions of something worse?"
+
+"Y-yes--but nothing definite. Now, take this case. If I should die
+childless, after my wife, the Atherton estate would descend to my
+nearest relative, Burroughs Atherton, a cousin."
+
+"Unless you willed it to--"
+
+"I have already drawn a will," he interrupted, "and in case I
+survive Eugenia and die childless, the money goes to the founding
+of a larger Eugenics Bureau, to prevent in the future, as much as
+possible, tragedies such as this of which I find myself a part. If
+the case is reversed, Eugenia will get her third and the remainder
+will go to the Bureau or the Foundation, as I call the new
+venture. But," and here young Atherton leaned forward and fixed
+his large eyes keenly on us, "Burroughs might break the will. He
+might show that I was of unsound mind, or that Eugenia was, too."
+
+"Are there no other relatives?"
+
+"Burroughs is the nearest," he replied, then added frankly, "I
+have a second cousin, a young lady named Edith Atherton, with whom
+both Burroughs and I used to be very friendly."
+
+It was evident from the way he spoke that he had thought a great
+deal about Edith Atherton, and still thought well of her.
+
+"Your wife thinks it is Burroughs who is persecuting her?" asked
+Kennedy.
+
+Atherton shrugged his shoulders.
+
+"Does she get along badly with Edith? She knows her I presume?"
+
+"Of course. The fact is that since the death of her mother, Edith
+has been living with us. She is a splendid girl, and all alone in
+the world now, and I had hopes that in New York she might meet
+some one and marry well."
+
+Kennedy was looking squarely at Atherton, wondering whether he
+might ask a question without seeming impertinent. Atherton caught
+the look, read it, and answered quite frankly, "To tell the truth,
+I suppose I might have married Edith, before I met Eugenia, if
+Professor Crafts had not dissuaded me. But it wouldn't have been
+real love--nor wise. You know," he went on more frankly, now that
+the first hesitation was over and he realized that if he were to
+gain anything at all by Kennedy's services, there must be the
+utmost candor between them, "you know cousins may marry if the
+stocks are known to be strong. But if there is a defect, it is
+almost sure to be intensified. And so I--I gave up the idea--never
+had it, in fact, so strongly as to propose to her. And when I met
+Eugenia all the Athertons on the family tree couldn't have bucked
+up against the combination."
+
+He was deadly in earnest as he arose from the chair into which he
+had dropped after I came in.
+
+"Oh, it's terrible--this haunting fear, this obsession that I have
+had, that, in spite of all I have tried to do, some one, somehow,
+will defeat me. Then comes the situation, just at a time when
+Eugenia and I feel that we have won against Fate, and she in
+particular needs all the consideration and care in the world--and-
+-and I am defeated."
+
+Atherton was again pacing the laboratory.
+
+"I have my car waiting outside," he pleaded. "I wish you would go
+with me to see Eugenia--now."
+
+It was impossible to resist him. Kennedy rose and I followed, not
+without a trace of misgiving.
+
+The Atherton mansion was one of the old houses of the city, a
+somber stone dwelling with a garden about it on a downtown square,
+on which business was already encroaching. We were admitted by a
+servant who seemed to walk over the polished floors with stealthy
+step as if there was something sacred about even the Atherton
+silence. As we waited in a high-ceilinged drawing-room with
+exquisite old tapestries on the walls, I could not help feeling
+myself the influence of wealth and birth that seemed to cry out
+from every object of art in the house.
+
+On the longer wall of the room, I saw a group of paintings. One, I
+noted especially, must have been Atherton's ancestor, the founder
+of the line. There was the same nose in Atherton, for instance, a
+striking instance of heredity. I studied the face carefully. There
+was every element of strength in it, and I thought instinctively
+that, whatever might have been the effects of in-breeding and bad
+alliances, there must still be some of that strength left in the
+present descendant of the house of Atherton. The more I thought
+about the house, the portrait, the whole case, the more unable was
+I to get out of my head a feeling that though I had not been in
+such a position before, I had at least read or heard something of
+which it vaguely reminded me.
+
+Eugenia Atherton was reclining listlessly in her room in a deep
+leather easy chair, when Atherton took us up at last. She did not
+rise to greet us, but I noted that she was attired in what Kennedy
+once called, as we strolled up the Avenue, "the expensive
+sloppiness of the present styles." In her case the looseness with
+which her clothes hung was exaggerated by the lack of energy with
+which she wore them.
+
+She had been a beautiful girl, I knew. In fact, one could see that
+she must have been. Now, however, she showed marks of change. Her
+eyes were large, and protruding, not with the fire of passion
+which is often associated with large eyes, but dully, set in a
+puffy face, a trifle florid. Her hands seemed, when she moved
+them, to shake with an involuntary tremor, and in spite of the
+fact that one almost could feel that her heart and lungs were
+speeding with energy, she had lost weight and no longer had the
+full, rounded figure of health. Her manner showed severe mental
+disturbance, indifference, depression, a distressing
+deterioration. All her attractive Western breeziness was gone. One
+felt the tragedy of it only too keenly.
+
+"I have asked Professor Kennedy, a specialist, to call, my dear,"
+said Atherton gently, without mentioning what the specialty was.
+
+"Another one?" she queried languorously.
+
+There was a colorless indifference in the tone which was almost
+tragic. She said the words slowly and deliberately, as though even
+her mind worked that way.
+
+From the first, I saw that Kennedy had been observing Eugenia
+Atherton keenly. And in the role of specialist in nervous diseases
+he was enabled to do what otherwise would have been difficult to
+accomplish.
+
+Gradually, from observing her mental condition of indifference
+which made conversation extremely difficult as well as profitless,
+he began to consider her physical condition. I knew him well
+enough to gather from his manner alone as he went on that what had
+seemed at the start to be merely a curious case, because it
+concerned the Athertons, was looming up in his mind as unusual in
+itself, and was interesting him because it baffled him.
+
+Craig had just discovered that her pulse was abnormally high, and
+that consequently she had a high temperature, and was sweating
+profusely.
+
+"Would you mind turning your head, Mrs. Atherton?" he asked.
+
+She turned slowly, half way, her eyes fixed vacantly on the floor
+until we could see the once striking profile.
+
+"No, all the way around, if you please," added Kennedy.
+
+She offered no objection, not the slightest resistance. As she
+turned her head as far as she could, Kennedy quickly placed his
+forefinger and thumb gently on her throat, the once beautiful
+throat, now with skin harsh and rough. Softly he moved his fingers
+just a fraction of an inch over the so-called "Adam's apple" and
+around it for a little distance.
+
+"Thank you," he said. "Now around to the other side."
+
+He made no other remark as he repeated the process, but I fancied
+I could tell that he had had an instant suspicion of something the
+moment he touched her throat.
+
+He rose abstractedly, bowed, and we started to leave the room,
+uncertain whether she knew or cared. Quincy had fixed his eyes
+silently on Craig, as if imploring him to speak, but I knew how
+unlikely that was until he had confirmed his suspicion to the last
+slightest detail.
+
+We were passing through a dressing room in the suite when we met a
+tall young woman, whose face I instantly recognized, not because I
+had ever seen it before, but because she had the Atherton nose so
+prominently developed.
+
+"My cousin, Edith," introduced Quincy.
+
+We bowed and stood for a moment chatting. There seemed to be no
+reason why we should leave the suite, since Mrs. Atherton paid so
+little attention to us even when we had been in the same room. Yet
+a slight movement in her room told me that in spite of her
+lethargy she seemed to know that we were there and to recognize
+who had joined us.
+
+Edith Atherton was a noticeable woman, a woman of temperament, not
+beautiful exactly, but with a stateliness about her, an aloofness.
+The more I studied her face, with its thin sensitive lips and
+commanding, almost imperious eyes, the more there seemed to be
+something peculiar about her. She was dressed very simply in
+black, but it was the simplicity that costs. One thing was quite
+evident--her pride in the family of Atherton.
+
+And as we talked, it seemed to be that she, much more than Eugenia
+in her former blooming health, was a part of the somber house.
+There came over me again the impression I had received before that
+I had read or heard something like this case before.
+
+She did not linger long, but continued her stately way into the
+room where Eugenia sat. And at once it flashed over me what my
+impression, indefinable, half formed, was. I could not help
+thinking, as I saw her pass, of the lady Madeline in "The Fall of
+the House of Usher."
+
+
+
+
+CHAPTER XXXII
+
+THE GERM PLASM
+
+
+I regarded her with utter astonishment and yet found it impossible
+to account for such a feeling. I looked at Atherton, but on his
+face I could see nothing but a sort of questioning fear that only
+increased my illusion, as if he, too, had only a vague, haunting
+premonition of something terrible impending. Almost I began to
+wonder whether the Atherton house might not crumble under the
+fierceness of a sudden whirlwind, while the two women in this
+case, one representing the wasted past, the other the blasted
+future, dragged Atherton down, as the whole scene dissolved into
+some ghostly tarn. It was only for a moment, and then I saw that
+the more practical Kennedy had been examining some bottles on the
+lady's dresser before which we had paused.
+
+One was a plain bottle of pellets which might have been some
+homeopathic remedy.
+
+"Whatever it is that is the matter with Eugenia," remarked
+Atherton, "it seems to have baffled the doctors so far."
+
+Kennedy said nothing, but I saw that he had clumsily overturned
+the bottle and absently set it up again, as though his thoughts
+were far away. Yet with a cleverness that would have done credit
+to a professor of legerdemain he had managed to extract two or
+three of the pellets.
+
+"Yes," he said, as he moved slowly toward the staircase in the
+wide hall, "most baffling."
+
+Atherton was plainly disappointed. Evidently he had expected
+Kennedy to arrive at the truth and set matters right by some
+sudden piece of wizardry, and it was with difficulty that he
+refrained from saying so.
+
+"I should like to meet Burroughs Atherton," he remarked as we
+stood in the wide hall on the first floor of the big house. "Is he
+a frequent visitor?"
+
+"Not frequent," hastened Quincy Atherton, in a tone that showed
+some satisfaction in saying it. "However, by a lucky chance he has
+promised to call to-night--a mere courtesy, I believe, to Edith,
+since she has come to town on a visit."
+
+"Good!" exclaimed Kennedy. "Now, I leave it to you, Atherton, to
+make some plausible excuse for our meeting Burroughs here."
+
+"I can do that easily."
+
+"I shall be here early," pursued Kennedy as we left.
+
+Back again in the laboratory to which Atherton insisted on
+accompanying us in his car, Kennedy busied himself for a few
+minutes, crushing up one of the tablets and trying one or two
+reactions with some of the powder dissolved, while I looked on
+curiously.
+
+"Craig," I remarked contemplatively, after a while, "how about
+Atherton himself? Is he really free from the--er--stigmata, I
+suppose you call them, of insanity?"
+
+"You mean, may the whole trouble lie with him?" he asked, not
+looking up from his work.
+
+"Yes--and the effect on her be a sort of reflex, say, perhaps the
+effect of having sold herself for money and position. In other
+words, does she, did she, ever love him? We don't know that. Might
+it not prey on her mind, until with the kind help of his precious
+relatives even Nature herself could not stand the strain--
+especially in the delicate condition in which she now finds
+herself?"
+
+I must admit that I felt the utmost sympathy for the poor girl
+whom we had just seen such a pitiable wreck.
+
+Kennedy closed his eyes tightly until they wrinkled at the
+corners.
+
+"I think I have found out the immediate cause of her trouble," he
+said simply, ignoring my suggestion.
+
+"What is it?" I asked eagerly.
+
+"I can't imagine how they could have failed to guess it, except
+that they never would have suspected to look for anything
+resembling exophthalmic goiter in a person of her stamina," he
+answered, pronouncing the word slowly. "You have heard of the
+thyroid gland in the neck?"
+
+"Yes?" I queried, for it was a mere name to me.
+
+"It is a vascular organ lying under the chin with a sort of little
+isthmus joining the two parts on either side of the windpipe," he
+explained. "Well, when there is any deterioration of those glands
+through any cause, all sorts of complications may arise. The
+thyroid is one of the so-called ductless glands, like the adrenals
+above the kidneys, the pineal gland and the pituitary body. In
+normal activity they discharge into the blood substances which are
+carried to other organs and are now known to be absolutely
+essential.
+
+"The substances which they secrete are called 'hormones'--those
+chemical messengers, as it were, by which many of the processes of
+the body are regulated. In fact, no field of experimental
+physiology is richer in interest than this. It seems that few
+ordinary drugs approach in their effects on metabolism the
+hormones of the thyroid. In excess they produce such diseases as
+exophthalmic goiter, and goiter is concerned with the enlargement
+of the glands and surrounding tissues beyond anything like natural
+size. Then, too, a defect in the glands causes the disease known
+as myxedema in adults and cretinism in children. Most of all, the
+gland seems to tell on the germ plasm of the body, especially in
+women."
+
+I listened in amazement, hardly knowing what to think. Did his
+discovery portend something diabolical, or was it purely a defect
+in nature which Dr. Crafts of the Eugenics Bureau had overlooked?
+
+"One thing at a time, Walter," cautioned Kennedy, when I put the
+question to him, scarcely expecting an answer yet.
+
+That night in the old Atherton mansion, while we waited for
+Borroughs to arrive, Kennedy, whose fertile mind had contrived to
+kill at least two birds with one stone, busied himself by cutting
+in on the regular telephone line and placing an extension of his
+own in a closet in the library. To it he attached an ordinary
+telephone receiver fastened to an arrangement which was strange to
+me. As nearly as I can describe it, between the diaphragm of the
+regular receiver and a brownish cylinder, like that of a
+phonograph, and with a needle attached, was fitted an air chamber
+of small size, open to the outer air by a small hole to prevent
+compression.
+
+The work was completed expeditiously, but we had plenty of time to
+wait, for Borroughs Atherton evidently did not consider that an
+evening had fairly begun until nine o'clock.
+
+He arrived at last, however, rather tall, slight of figure,
+narrow-shouldered, designed for the latest models of imported
+fabrics. It was evident merely by shaking hands with Burroughs
+that he thought both the Athertons and the Burroughses just the
+right combination. He was one of those few men against whom I
+conceive an instinctive prejudice, and in this case I felt
+positive that, whatever faults the Atherton germ plasm might
+contain, he had combined others from the determiners of that of
+the other ancestors he boasted. I could not help feeling that
+Eugenia Atherton was in about as unpleasant an atmosphere of
+social miasma as could be imagined.
+
+Burroughs asked politely after Eugenia, but it was evident that
+the real deference was paid to Edith Atherton and that they got
+along very well together. Burroughs excused himself early, and we
+followed soon after.
+
+"I think I shall go around to this Eugenics Bureau of Dr. Crafts,"
+remarked Kennedy the next day, after a night's consideration of
+the case.
+
+The Bureau occupied a floor in a dwelling house uptown which had
+been remodeled into an office building. Huge cabinets were stacked
+up against the walls, and in them several women were engaged in
+filing blanks and card records. Another part of the office
+consisted of an extensive library on eugenic subjects.
+
+Dr. Crafts, in charge of the work, whom we found in a little
+office in front partitioned off by ground glass, was an old man
+with an alert, vigorous mind on whom the effects of plain living
+and high thinking showed plainly. He was looking over some new
+blanks with a young woman who seemed to be working with him,
+directing the force of clerks as well as the "field workers," who
+were gathering the vast mass of information which was being
+studied. As we introduced ourselves, he introduced Dr. Maude
+Schofield.
+
+"I have heard of your eugenic marriage contests," began Kennedy,
+"more especially of what you have done for Mr. Quincy Atherton."
+
+"Well--not exactly a contest in that case, at least," corrected
+Dr. Crafts with an indulgent smile for a layman.
+
+"No," put in Dr. Schofield, "the Eugenics Bureau isn't a human
+stock farm."
+
+"I see," commented Kennedy, who had no such idea, anyhow. He was
+always lenient with anyone who had what he often referred to as
+the "illusion of grandeur."
+
+"We advise people sometimes regarding the desirability or the
+undesirability of marriage," mollified Dr. Crafts. "This is a sort
+of clearing house for scientific race investigation and
+improvement."
+
+"At any rate," persisted Kennedy, "after investigation, I
+understand, you advised in favor of his marriage with Miss
+Gilman."
+
+"Yes, Eugenia Gilman seemed to measure well up to the requirements
+in such a match. Her branch of the Gilmans has always been of the
+vigorous, pioneering type, as well as intellectual. Her father was
+one of the foremost thinkers in the West; in fact had long held
+ideas on the betterment of the race. You see that in the choice of
+a name for his daughter--Eugenia."
+
+"Then there were no recessive traits in her family," asked Kennedy
+quickly, "of the same sort that you find in the Athertons?"
+
+"None that we could discover," answered Dr. Crafts positively.
+
+"No epilepsy, no insanity of any form?"
+
+"No. Of course, you understand that almost no one is what might be
+called eugenically perfect. Strictly speaking, perhaps not over
+two or three per cent. of the population even approximates that
+standard. But it seemed to me that in everything essential in this
+case, weakness latent in Atherton was mating strength in Eugenia
+and the same way on her part for an entirely different set of
+traits."
+
+"Still," considered Kennedy, "there might have been something
+latent in her family germ plasm back of the time through which you
+could trace it?"
+
+Dr. Crafts shrugged his shoulders. "There often is, I must admit,
+something we can't discover because it lies too far back in the
+past."
+
+"And likely to crop out after skipping generations," put in Maude
+Schofield.
+
+She evidently did not take the same liberal view in the practical
+application of the matter expressed by her chief. I set it down to
+the ardor of youth in a new cause, which often becomes the saner
+conservatism of maturity.
+
+"Of course, you found it much easier than usual to get at the true
+family history of the Athertons," pursued Kennedy. "It is an old
+family and has been prominent for generations."
+
+"Naturally," assented Dr. Crafts.
+
+"You know Burroughs Atherton on both lines of descent?" asked
+Kennedy, changing the subject abruptly.
+
+"Yes, fairly well," answered Crafts.
+
+"Now, for example," went on Craig, "how would you advise him to
+marry?"
+
+I saw at once that he was taking this subterfuge as a way of
+securing information which might otherwise have been withheld if
+asked for directly. Maude Schofield also saw it, I fancied, but
+this time said nothing. "They had a grandfather who was a manic
+depressive on the Atherton side," said Crafts slowly. "Now, no
+attempt has ever been made to breed that defect out of the family.
+In the case of Burroughs, it is perhaps a little worse, for the
+other side of his ancestry is not free from the taint of
+alcoholism."
+
+"And Edith Atherton?"
+
+"The same way. They both carry it. I won't go into the Mendelian
+law on the subject. We are clearing up much that is obscure. But
+as to Burroughs, he should marry, if at all, some one without that
+particular taint. I believe that in a few generations by proper
+mating most taints might be bred out of families."
+
+Maude Schofield evidently did not agree with Dr. Crafts on some
+point, and, noticing it, he seemed to be in the position both of
+explaining his contention to us and of defending it before his
+fair assistant.
+
+"It is my opinion, as far as I have gone with the data," he added,
+"that there is hope for many of those whose family history shows
+certain nervous taints. A sweeping prohibition of such marriages
+would be futile, perhaps injurious. It is necessary that the
+mating be carefully made, however, to prevent intensifying the
+taint. You see, though I am a eugenist I am not an extremist."
+
+He paused, then resumed argumentatively: "Then there are other
+questions, too, like that of genius with its close relation to
+manic depressive insanity. Also, there is decrease enough in the
+birth rate, without adding an excuse for it. No, that a young man
+like Atherton should take the subject seriously, instead of
+spending his time in wild dissipation, like his father, is
+certainly creditable, argues in itself that there still must exist
+some strength in his stock.
+
+"And, of course," he continued warmly, "when I say that weakness
+in a trait--not in all traits, by any means--should marry strength
+and that strength may marry weakness, I don't mean that all
+matches should be like that. If we are too strict we may prohibit
+practically all marriages. In Atherton's case, as in many another,
+I felt that I should interpret the rule as sanely as possible."
+
+"Strength should marry strength, and weakness should never marry,"
+persisted Maude Schofield. "Nothing short of that will satisfy the
+true eugenist."
+
+"Theoretically," objected Crafts. "But Atherton was going to
+marry, anyhow. The only thing for me to do was to lay down a rule
+which he might follow safely. Besides, any other rule meant sure
+disaster."
+
+"It was the only rule with half a chance of being followed and at
+any rate," drawled Kennedy, as the eugenists wrangled, "what
+difference does it make in this case? As nearly as I can make out
+it is Mrs. Atherton herself, not Atherton, who is ill."
+
+Maude Schofield had risen to return to supervising a clerk who
+needed help. She left us, still unconvinced.
+
+"That is a very clever girl," remarked Kennedy as she shut the
+door and he scanned Dr. Crafts' face dosely.
+
+"Very," assented the Doctor.
+
+"The Schofields come of good stock?" hazarded Kennedy.
+
+"Very," assented Dr. Crafts again.
+
+Evidently he did not care to talk about individual cases, and I
+felt that the rule was a safe one, to prevent Eugenics from
+becoming Gossip. Kennedy thanked him for his courtesy, and we left
+apparently on the best of terms both with Crafts and his
+assistant.
+
+
+
+
+CHAPTER XXXIII
+
+THE SEX CONTROL
+
+
+I did not see Kennedy again that day until late in the afternoon,
+when he came into the laboratory carrying a small package.
+
+"Theory is one thing, practice is another," he remarked, as he
+threw his hat and coat into a chair.
+
+"Which means--in this case?" I prompted.
+
+"Why, I have just seen Atherton. Of course I didn't repeat our
+conversation of this morning, and I'm glad I didn't. He almost
+makes me think you are right, Walter. He's obsessed by the fear of
+Burroughs. Why, he even told me that Burroughs had gone so far as
+to take a leaf out of his book, so to speak, get in touch with the
+Eugenics Bureau as if to follow his footsteps, but really to pump
+them about Atherton himself. Atherton says it's all Burroughs'
+plan to break his will and that the fellow has even gone so far as
+to cultivate the acquaintance of Maude Schofield, knowing that he
+will get no sympathy from Crafts."
+
+"First it was Edith Atherton, now it is Maude Schofield that he
+hitches up with Burroughs," I commented. "Seems to me that I have
+heard that one of the first signs of insanity is belief that
+everyone about the victim is conspiring against him. I haven't any
+love for any of them--but I must be fair."
+
+"Well," said Kennedy, unwrapping the package, "there IS this much
+to it. Atherton says Burroughs and Maude Schofield have been seen
+together more than once--and not at intellectual gatherings
+either. Burroughs is a fascinating fellow to a woman, if he wants
+to be, and the Schofields are at least the social equals of the
+Burroughs. Besides," he added, "in spite of eugenics, feminism,
+and all the rest--sex, like murder, will out. There's no use
+having any false ideas about THAT. Atherton may see red--but,
+then, he was quite excited."
+
+"Over what?" I asked, perplexed more than ever at the turn of
+events.
+
+"He called me up in the first place. 'Can't you do something?' he
+implored. 'Eugenia is getting worse all the time.' She is, too. I
+saw her for a moment, and she was even more vacant than
+yesterday."
+
+The thought of the poor girl in the big house somehow brought over
+me again my first impression of Poe's story.
+
+Kennedy had unwrapped the package which proved to be the
+instrument he had left in the closet at Atherton's. It was, as I
+had observed, like an ordinary wax cylinder phonograph record.
+
+"You see," explained Kennedy, "it is nothing more than a
+successful application at last of, say, one of those phonographs
+you have seen in offices for taking dictation, placed so that the
+feebler vibrations of the telephone affect it. Let us see what we
+have here."
+
+He had attached the cylinder to an ordinary phonograph, and after
+a number of routine calls had been run off, he came to this, in
+voices which we could only guess at but not recognize, for no
+names were used.
+
+"How is she to-day?"
+
+"Not much changed--perhaps not so well."
+
+"It's all right, though. That is natural. It is working well. I
+think you might increase the dose, one tablet."
+
+"You're sure it is all right?" (with anxiety).
+
+"Oh, positively--it has been done in Europe."
+
+"I hope so. It must be a boy--and an ATHERTON?"
+
+"Never fear."
+
+That was all. Who was it? The voices were unfamiliar to me,
+especially when repeated mechanically. Besides they may have been
+disguised. At any rate we had learned something. Some one was
+trying to control the sex of the expected Atherton heir. But that
+was about all. Who it was, we knew no better, apparently, than
+before.
+
+Kennedy did not seem to care much, however. Quickly he got Quincy
+Atherton on the wire and arranged for Atherton to have Dr. Crafts
+meet us at the house at eight o'clock that night, with Maude
+Schofield. Then he asked that Burroughs Atherton be there, and of
+course, Edith and Eugenia.
+
+We arrived almost as the clock was striking, Kennedy carrying the
+phonograph record and another blank record, and a boy tugging
+along the machine itself. Dr. Crafts was the next to appear,
+expressing surprise at meeting us, and I thought a bit annoyed,
+for he mentioned that it had been with reluctance that he had had
+to give up some work he had planned for the evening. Maude
+Schofield, who came with him, looked bored. Knowing that she
+disapproved of the match with Eugenia, I was not surprised.
+Burroughs arrived, not as late as I had expected, but almost
+insultingly supercilious at finding so many strangers at what
+Atherton had told him was to be a family conference, in order to
+get him to come. Last of all Edith Atherton descended the
+staircase, the personification of dignity, bowing to each with a
+studied graciousness, as if distributing largess, but greeting
+Burroughs with an air that plainly showed how much thicker was
+blood than water. Eugenia remained upstairs, lethargic, almost
+cataleptic, as Atherton told us when we arrived.
+
+"I trust you are not going to keep us long, Quincy," yawned
+Burroughs, looking ostentatiously at his watch.
+
+"Only long enough for Professor Kennedy to say a few words about
+Eugenia," replied Atherton nervously, bowing to Kennedy.
+
+Kennedy cleared his throat slowly.
+
+"I don't know that I have much to say," began Kennedy, still
+seated. "I suppose Mr. Atherton has told you I have been much
+interested in the peculiar state of health of Mrs. Atherton?"
+
+No one spoke, and he went on easily: "There is something I might
+say, however, about the--er--what I call the chemistry of
+insanity. Among the present wonders of science, as you doubtless
+know, none stirs the imagination so powerfully as the doctrine
+that at least some forms of insanity are the result of chemical
+changes in the blood. For instance, ill temper, intoxication, many
+things are due to chemical changes in the blood acting on the
+brain.
+
+"Go further back. Take typhoid fever with its delirium, influenza
+with its suicide mania. All due to toxins--poisons. Chemistry--
+chemistry--all of them chemistry."
+
+Craig had begun carefully so as to win their attention. He had it
+as he went on: "Do we not brew within ourselves poisons which
+enter the circulation and pervade the system? A sudden emotion
+upsets the chemistry of the body. Or poisonous food. Or a drug. It
+affects many things. But we could never have had this chemical
+theory unless we had had physiological chemistry--and some carry
+it so far as to say that the brain secretes thought, just as the
+liver secretes bile, that thoughts are the results of molecular
+changes."
+
+"You are, then, a materialist of the most pronounced type,"
+asserted Dr. Crafts.
+
+Kennedy had been reaching over to a table, toying with the
+phonograph. As Crafts spoke he moved a key, and I suspected that
+it was in order to catch the words.
+
+"Not entirely," he said. "No more than some eugenists."
+
+"In our field," put in Maude Schofield, "I might express the
+thought this way--the sociologist has had his day; now it is the
+biologist, the eugenist."
+
+"That expresses it," commented Kennedy, still tinkering with the
+record. "Yet it does not mean that because we have new ideas, they
+abolish the old. Often they only explain, amplify, supplement. For
+instance," he said, looking up at Edith Atherton, "take heredity.
+Our knowledge seems new, but is it? Marriages have always been
+dictated by a sort of eugenics. Society is founded on that."
+
+"Precisely," she answered. "The best families have always married
+into the best families. These modern notions simply recognize what
+the best people have always thought--except that it seems to me,"
+she added with a sarcastic flourish, "people of no ancestry are
+trying to force themselves in among their betters."
+
+"Very true, Edith," drawled Burroughs, "but we did not have to be
+brought here by Quincy to learn that."
+
+Quincy Atherton had risen during the discussion and had approached
+Kennedy. Craig continued to finger the phonograph abstractedly, as
+he looked up.
+
+"About this--this insanity theory," he whispered eagerly. "You
+think that the suspicions I had have been justified?"
+
+I had been watching Kennedy's hand. As soon as Atherton had
+started to speak, I saw that Craig, as before, had moved the key,
+evidently registering what he said, as he had in the case of the
+others during the discussion.
+
+"One moment, Atherton," he whispered in reply, "I'm coming to
+that. Now," he resumed aloud, "there is a disease, or a number of
+diseases, to which my remarks about insanity a while ago might
+apply very well. They have been known for some time to arise from
+various affections of the thyroid glands in the neck. These
+glands, strange to say, if acted on in certain ways can cause
+degenerations of mind and body, which are well known, but in spite
+of much study are still very little understood. For example, there
+is a definite interrelation between them and sex--especially in
+woman."
+
+Rapidly he sketched what he had already told me of the thyroid and
+the hormones. "These hormones," added Kennedy, "are closely
+related to many reactions in the body, such as even the mother's
+secretion of milk at the proper time and then only. That and many
+other functions are due to the presence and character of these
+chemical secretions from the thyroid and other ductless glands. It
+is a fascinating study. For we know that anything that will upset-
+-reduce or increase--the hormones is a matter intimately concerned
+with health. Such changes," he said earnestly, leaning forward,
+"might be aimed directly at the very heart of what otherwise would
+be a true eugenic marriage. It is even possible that loss of sex
+itself might be made to follow deep changes of the thyroid."
+
+He stopped a moment. Even if he had accomplished nothing else he
+had struck a note which had caused the Athertons to forget their
+former superciliousness.
+
+"If there is an oversupply of thyroid hormones," continued Craig,
+"that excess will produce many changes, for instance a condition
+very much like exophthalmic goiter. And," he said, straightening
+up, "I find that Eugenia Atherton has within her blood an undue
+proportion of these thyroid hormones. Now, is it overfunction of
+the glands, hyper-secretion--or is it something else?"
+
+No one moved as Kennedy skillfully led his disclosure along step
+by step.
+
+"That question," he began again slowly, shifting his position in
+the chair, "raises in my mind, at least, a question which has
+often occurred to me before. Is it possible for a person, taking
+advantage of the scientific knowledge we have gained, to devise
+and successfully execute a murder without fear of discovery? In
+other words, can a person be removed with that technical nicety of
+detail which will leave no clue and will be set down as something
+entirely natural, though unfortunate?"
+
+It was a terrible idea he was framing, and he dwelt on it so that
+we might accept it at its full value. "As one doctor has said," he
+added, "although toxicologists and chemists have not always
+possessed infallible tests for practical use, it is at present a
+pretty certain observation that every poison leaves its mark. But
+then on the other hand, students of criminology have said that a
+skilled physician or surgeon is about the only person now capable
+of carrying out a really scientific murder.
+
+"Which is true? It seems to me, at least in the latter case, that
+the very nicety of the handiwork must often serve as a clue in
+itself. The trained hand leaves the peculiar mark characteristic
+of its training. No matter how shrewdly the deed is planned, the
+execution of it is daily becoming a more and more difficult feat,
+thanks to our increasing knowledge of microbiology and pathology."
+
+He had risen, as he finished the sentence, every eye fixed on him,
+as if he had been a master hypnotist.
+
+"Perhaps," he said, taking off the cylinder from the phonograph
+and placing on one which I knew was that which had lain in the
+library closet over night, "perhaps some of the things I have said
+will explain or be explained by the record on this cylinder."
+
+He had started the machine. So magical was the effect on the
+little audience that I am tempted to repeat what I had already
+heard, but had not myself yet been able to explain:
+
+"How is she to-day?"
+
+"Not much changed--perhaps not so well."
+
+"It's all right, though. That is natural. It is working well. I
+think you might increase the dose one tablet."
+
+"You're sure it is all right?"
+
+"Oh, positively--it has been done in Europe."
+
+"I hope so. It must be a boy--and an ATHERTON."
+
+"Never fear."
+
+No one moved a muscle. If there was anyone in the room guilty of
+playing on the feelings and the health of an unfortunate woman,
+that person must have had superb control of his own feelings.
+
+"As you know," resumed Kennedy thoughtfully, "there are and have
+been many theories of sex control. One of the latest, but by no
+means the only one, is that it can be done by use of the extracts
+of various glands administered to the mother. I do not know with
+what scientific authority it was stated, but I do know that some
+one has recently said that adrenalin, derived from the suprarenal
+glands, induces boys to develop--cholin, from the bile of the
+liver, girls. It makes no difference--in this case. There may have
+been a show of science. But it was to cover up a crime. Some one
+has been administering to Eugenia Atherton tablets of thyroid
+extract--ostensibly to aid her in fulfilling the dearest ambition
+of her soul--to become the mother of a new line of Athertons which
+might bear the same relation to the future of the country as the
+great family of the Edwards mothered by Elizabeth Tuttle."
+
+He was bending over the two phonograph cylinders now, rapidly
+comparing the new one which he had made and that which he had just
+allowed to reel off its astounding revelation.
+
+"When a voice speaks into a phonograph," he said, half to himself,
+"its modulations received on the diaphragm are written by a needle
+point upon the surface of a cylinder or disk in a series of fine
+waving or zigzag lines of infinitely varying depth or breadth. Dr.
+Marage and others have been able to distinguish vocal sounds by
+the naked eye on phonograph records. Mr. Edison has studied them
+with the microscope in his world-wide search for the perfect
+voice.
+
+"In fact, now it is possible to identify voices by the records
+they make, to get at the precise meaning of each slightest
+variation of the lines with mathematical accuracy. They can no
+more be falsified than handwriting can be forged so that modern
+science cannot detect it or than typewriting can be concealed and
+attributed to another machine. The voice is like a finger print, a
+portrait parle--unescapable."
+
+He glanced up, then back again. "This microscope shows me," he
+said, "that the voices on that cylinder you heard are identical
+with two on this record which I have just made in this room."
+
+"Walter," he said, motioning to me, "look."
+
+I glanced into the eyepiece and saw a series of lines and curves,
+peculiar waves lapping together and making an appearance in some
+spots almost like tooth marks. Although I did not understand the
+details of the thing, I could readily see that by study one might
+learn as much about it as about loops, whorls, and arches on
+finger tips.
+
+"The upper and lower lines," he explained, "with long regular
+waves, on that highly magnified section of the record, are formed
+by the voice with no overtones. The three lines in the middle,
+with rhythmic ripples, show the overtones."
+
+He paused a moment and faced us. "Many a person," he resumed, "is
+a biotype in whom a full complement of what are called inhibitions
+never develops. That is part of your eugenics. Throughout life,
+and in spite of the best of training, that person reacts now and
+then to a certain stimulus directly. A man stands high; once a
+year he falls with a lethal quantity of alcohol. A woman,
+brilliant, accomplished, slips away and spends a day with a lover
+as unlike herself as can be imagined.
+
+"The voice that interests me most on these records," he went on,
+emphasizing the words with one of the cylinders which he still
+held, "is that of a person who has been working on the family
+pride of another. That person has persuaded the other to
+administer to Eugenia an extract because 'it must be a boy and an
+Atherton.' That person is a high-class defective, born with a
+criminal instinct, reacting to it in an artful way. Thank God, the
+love of a man whom theoretical eugenics condemned, roused us in--"
+
+A cry at the door brought us all to our feet, with hearts thumping
+as if they were bursting.
+
+It was Eugenia Atherton, wild-eyed, erect, staring.
+
+I stood aghast at the vision. Was she really to be the Lady
+Madeline in this fall of the House of Atherton?
+
+"Edith--I--I missed you. I heard voices. Is--is it true--what this
+man--says? Is my--my baby--"
+
+Quincy Atherton leaped forward and caught her as she reeled.
+Quickly Craig threw open a window for air, and as he did so leaned
+far out and blew shrilly on a police whistle.
+
+The young man looked up from Eugenia, over whom he was bending,
+scarcely heeding what else went on about him. Still, there was no
+trace of anger on his face, in spite of the great wrong that had
+been done him. There was room for only one great emotion--only
+anxiety for the poor girl who had suffered so cruelly merely for
+taking his name.
+
+Kennedy saw the unspoken question in his eyes.
+
+"Eugenia is a pure normal, as Dr. Crafts told you," he said
+gently. "A few weeks, perhaps only days, of treatment--the thyroid
+will revert to its normal state--and Eugenia Gilman will be the
+mother of a new house of Atherton which may eclipse even the proud
+record of the founder of the old."
+
+"Who blew the whistle?" demanded a gruff voice at the door, as a
+tall bluecoat puffed past the scandalized butler.
+
+"Arrest that woman," pointed Kennedy. "She is the poisoner. Either
+as wife of Burroughs, whom she fascinates and controls as she does
+Edith, she planned to break the will of Quincy or, in the other
+event, to administer the fortune as head of the Eugenics
+Foundation after the death of Dr. Crafts, who would have followed
+Eugenia and Quincy Atherton."
+
+I followed the direction of Kennedy's accusing finger. Maude
+Schofield's face betrayed more than even her tongue could have
+confessed.
+
+
+
+
+CHAPTER XXXIV
+
+THE BILLIONAIRE BABY
+
+
+Coming to us directly as a result of the talk that the Atherton
+case provoked was another that involved the happiness of a wealthy
+family to a no less degree.
+
+"I suppose you have heard of the 'billionaire baby,' Morton
+Hazleton III?" asked Kennedy of me one afternoon shortly
+afterward.
+
+The mere mention of the name conjured up in my mind a picture of
+the lusty two-year-old heir of two fortunes, as the feature
+articles in the Star had described that little scion of wealth--
+his luxurious nursery, his magnificent toys, his own motor car, a
+trained nurse and a detective on guard every hour of the day and
+night, every possible precaution for his health and safety.
+
+"Gad, what a lucky kid!" I exclaimed involuntarily.
+
+"Oh, I don't know about that," put in Kennedy. "The fortune may be
+exaggerated. His happiness is, I'm sure."
+
+He had pulled from his pocketbook a card and handed it to me. It
+read: "Gilbert Butler, American representative, Lloyd's."
+
+"Lloyd's?" I queried. "What has Lloyd's to do with the billion-
+dollar baby?"
+
+"Very much. The child has been insured with them for some fabulous
+sum against accident, including kidnaping."
+
+"Yes?" I prompted, "sensing" a story.
+
+"Well, there seem to have been threats of some kind, I understand.
+Mr. Butler has called on me once already to-day to retain my
+services and is going to--ah--there he is again now."
+
+Kennedy had answered the door buzzer himself, and Mr. Butler, a
+tall, sloping-shouldered Englishman, entered.
+
+"Has anything new developed?" asked Kennedy, introducing me.
+
+"I can't say," replied Butler dubiously. "I rather think we have
+found something that may have a bearing on the case. You know Miss
+Haversham, Veronica Haversham?"
+
+"The actress and professional beauty? Yes--at least I have seen
+her. Why?"
+
+"We hear that Morton Hazleton knows her, anyhow," remarked Butler
+dryly.
+
+"Well?"
+
+"Then you don't know the gossip?" he cut in. "She is said to be in
+a sanitarium near the city. I'll have to find that out for you.
+It's a fast set she has been traveling with lately, including not
+only Hazleton, but Dr. Maudsley, the Hazleton physician, and one
+or two others, who if they were poorer might be called desperate
+characters."
+
+"Does Mrs. Hazleton know of--of his reputed intimacy?"
+
+"I can't say that, either. I presume that she is no fool."
+
+Morton Hazleton, Jr., I knew, belonged to a rather smart group of
+young men. He had been mentioned in several near-scandals, but as
+far as I knew there had been nothing quite as public and definite
+as this one.
+
+"Wouldn't that account for her fears?" I asked.
+
+"Hardly," replied Butler, shaking his head. "You see, Mrs.
+Hazleton is a nervous wreck, but it's about the baby, and caused,
+she says, by her fears for its safety. It came to us only in a
+roundabout way, through a servant in the house who keeps us in
+touch. The curious feature is that we can seem to get nothing
+definite from her about her fears. They may be groundless."
+
+Butler shrugged his shoulders and proceeded, "And they may be
+well-founded. But we prefer to run no chances in a case of this
+kind. The child, you know, is guarded in the house. In his
+perambulator he is doubly guarded, and when he goes out for his
+airing in the automobile, two men, the chauffeur and a detective,
+are always there, besides his nurse, and often his mother or
+grandmother. Even in the nursery suite they have iron shutters
+which can be pulled down and padlocked at night and are
+constructed so as to give plenty of fresh air even to a scientific
+baby. Master Hazleton was the best sort of risk, we thought. But
+now--we don't know."
+
+"You can protect yourselves, though," suggested Kennedy.
+
+"Yes, we have, under the policy, the right to take certain
+measures to protect ourselves in addition to the precautions taken
+by the Hazletons. We have added our own detective to those already
+on duty. But we--we don't know what to guard against," he
+concluded, perplexed. "We'd like to know--that's all. It's too big
+a risk."
+
+"I may see Mrs. Hazleton?" mused Kennedy.
+
+"Yes. Under the circumstances she can scarcely refuse to see
+anyone we send. I've arranged already for you to meet her within
+an hour. Is that all right?"
+
+"Certainly."
+
+The Hazleton home in winter in the city was uptown, facing the
+river. The large grounds adjoining made the Hazletons quite
+independent of the daily infant parade which one sees along
+Riverside Drive.
+
+As we entered the grounds we could almost feel the very atmosphere
+on guard. We did not see the little subject of so much concern,
+but I remembered his much heralded advent, when his grandparents
+had settled a cold million on him, just as a reward for coming
+into the world. Evidently, Morton, Sr., had hoped that Morton,
+Jr., would calm down, now that there was a third generation to
+consider. It seemed that he had not. I wondered if that had really
+been the occasion of the threats or whatever it was that had
+caused Mrs. Hazleton's fears, and whether Veronica Haversham or
+any of the fast set around her had had anything to do with it.
+
+Millicent Hazleton was a very pretty little woman, in whom one saw
+instinctively the artistic temperament. She had been an actress,
+too, when young Morton Hazleton married her, and at first, at
+least, they had seemed very devoted to each other.
+
+We were admitted to see her in her own library, a tastefully
+furnished room on the second floor of the house, facing a garden
+at the side.
+
+"Mrs. Hazleton," began Butler, smoothing the way for us, "of
+course you realize that we are working in your interests.
+Professor Kennedy, therefore, in a sense, represents both of us."
+
+"I am quite sure I shall be delighted to help you," she said with
+an absent expression, though not ungraciously.
+
+Butler, having introduced us, courteously withdrew. "I leave this
+entirely in your hands," he said, as he excused himself. "If you
+want me to do anything more, call on me."
+
+I must say that I was much surprised at the way she had received
+us. Was there in it, I wondered, an element of fear lest if she
+refused to talk suspicion might grow even greater? One could see
+anxiety plainly enough on her face, as she waited for Kennedy to
+begin.
+
+A few moments of general conversation then followed.
+
+"Just what is it you fear?" he asked, after having gradually led
+around to the subject. "Have there been any threatening letters?"
+
+"N-no," she hesitated, "at least nothing--definite."
+
+"Gossip?" he hinted.
+
+"No." She said it so positively that I fancied it might be taken
+for a plain "Yes."
+
+"Then what is it?" he asked, very deferentially, but firmly.
+
+She had been looking out at the garden. "You couldn't understand,"
+she remarked. "No detective--" she stopped.
+
+"You may be sure, Mrs. Hazleton, that I have not come here
+unnecessarily to intrude," he reassured her. "It is exactly as Mr.
+Butler put it. We--want to help you."
+
+I fancied there seemed to be something compelling about his
+manner. It was at once sympathetic and persuasive. Quite evidently
+he was taking pains to break down the prejudice in her mind which
+she had already shown toward the ordinary detective.
+
+"You would think me crazy," she remarked slowly. "But it is just
+a--a dream--just dreams."
+
+I don't think she had intended to say anything, for she stopped
+short and looked at him quickly as if to make sure whether he
+could understand. As for myself, I must say I felt a little
+skeptical. To my surprise, Kennedy seemed to take the statement at
+its face value.
+
+"Ah," he remarked, "an anxiety dream? You will pardon me, Mrs.
+Hazleton, but before we go further let me tell you frankly that I
+am much more than an ordinary detective. If you will permit me, I
+should rather have you think of me as a psychologist, a
+specialist, one who has come to set your mind at rest rather than
+to worm things from you by devious methods against which you have
+to be on guard. It is just for such an unusual case as yours that
+Mr. Butler has called me in. By the way, as our interview may last
+a few minutes, would you mind sitting down? I think you'll find it
+easier to talk if you can get your mind perfectly at rest, and for
+the moment trust to the nurse and the detectives who are guarding
+the garden, I am sure, perfectly."
+
+She had been standing by the window during the interview and was
+quite evidently growing more and more nervous. With a bow Kennedy
+placed her at her ease on a chaise lounge.
+
+"Now," he continued, standing near her, but out of sight, "you
+must try to remain free from all external influences and
+impressions. Don't move. Avoid every use of a muscle. Don't let
+anything distract you. Just concentrate your attention on your
+psychic activities. Don't suppress one idea as unimportant,
+irrelevant, or nonsensical. Simply tell me what occurs to you in
+connection with the dreams--everything," emphasized Craig.
+
+I could not help feeling surprised to find that she accepted
+Kennedy's deferential commands, for after all that was what they
+amounted to. Almost I felt that she was turning to him for help,
+that he had broken down some barrier to her confidence. He seemed
+to exert a sort of hypnotic influence over her.
+
+"I have had cases before which involved dreams," he was saying
+quietly and reassuringly. "Believe me, I do not share the world's
+opinion that dreams are nothing. Nor yet do I believe in them
+superstitiously. I can readily understand how a dream can play a
+mighty part in shaping the feelings of a high-tensioned woman.
+Might I ask exactly what it is you fear in your dreams?"
+
+She sank her head back in the cushions, and for a moment closed
+her eyes, half in weariness, half in tacit obedience to him. "Oh,
+I have such horrible dreams," she said at length, "full of anxiety
+and fear for Morton and little Morton. I can't explain it. But
+they are so horrible."
+
+Kennedy said nothing. She was talking freely at last.
+
+"Only last night," she went on, "I dreamt that Morton was dead. I
+could see the funeral, all the preparations, and the procession.
+It seemed that in the crowd there was a woman. I could not see her
+face, but she had fallen down and the crowd was around her. Then
+Dr. Maudsley appeared. Then all of a sudden the dream changed. I
+thought I was on the sand, at the seashore, or perhaps a lake. I
+was with Junior and it seemed as if he were wading in the water,
+his head bobbing up and down in the waves. It was like a desert,
+too--the sand. I turned, and there was a lion behind me. I did not
+seem to be afraid of him, although I was so close that I could
+almost feel his shaggy mane. Yet I feared that he might bite
+Junior. The next I knew I was running with the child in my arms. I
+escaped--and--oh, the relief!"
+
+She sank back, half exhausted, half terrified still by the
+recollection.
+
+"In your dream when Dr. Maudsley appeared," asked Kennedy,
+evidently interested in filling in the gap, "what did he do?"
+
+"Do?" she repeated. "In the dream? Nothing."
+
+"Are you sure?" he asked, shooting a quick glance at her.
+
+"Yes. That part of the dream became indistinct. I'm sure he did
+nothing, except shoulder through the crowd. I think he had just
+entered. Then that part of the dream seemed to end and the second
+part began."
+
+Piece by piece Kennedy went over it, putting it together as if it
+were a mosaic.
+
+"Now, the woman. You say her face was hidden?"
+
+She hesitated. "N--no. I saw it. But it was no one I knew."
+
+Kennedy did not dwell on the contradiction, but added, "And the
+crowd?"
+
+"Strangers, too."
+
+"Dr. Maudsley is your family physician?" he questioned.
+
+"Yes."
+
+"Did he call--er--yesterday?"
+
+"He calls every day to supervise the nurse who has Junior in
+charge."
+
+"Could one always be true to oneself in the face of any
+temptation?" he asked suddenly.
+
+It was a bold question. Yet such had been the gradual manner of
+his leading up to it that, before she knew it, she had answered
+quite frankly, "Yes--if one always thought of home and her child,
+I cannot see how one could help controlling herself."
+
+She seemed to catch her breath, almost as though the words had
+escaped her before she knew it.
+
+"Is there anything besides your dream that alarms you," he asked,
+changing the subject quickly, "any suspicion of--say the
+servants?"
+
+"No," she said, watching him now. "But some time ago we caught a
+burglar upstairs here. He managed to escape. That has made me
+nervous. I didn't think it was possible."
+
+"Anything else?"
+
+"No," she said positively, this time on her guard.
+
+Kennedy saw that she had made up her mind to say no more.
+
+"Mrs. Hazleton," he said, rising. "I can hardly thank you too much
+for the manner in which you have met my questions. It will make it
+much easier for me to quiet your fears. And if anything else
+occurs to you, you may rest assured I shall violate no confidences
+in your telling me."
+
+I could not help the feeling, however, that there was just a
+little air of relief on her face as we left.
+
+
+
+
+CHAPTER XXXV
+
+THE PSYCHANALYSIS
+
+
+"H--M," mused Kennedy as we walked along after leaving the house.
+"There were several 'complexes,' as they are called, there--the
+most interesting and important being the erotic, as usual. Now,
+take the lion in the dream, with his mane. That, I suspect, was
+Dr. Maudsley. If you are acquainted with him, you will recall his
+heavy, almost tawny beard."
+
+Kennedy seemed to be revolving something in his mind and I did not
+interrupt. I had known him too long to feel that even a dream
+might not have its value with him. Indeed, several times before he
+had given me glimpses into the fascinating possibilities of the
+new psychology.
+
+"In spite of the work of thousands of years, little progress has
+been made in the scientific understanding of dreams," he remarked
+a few moments later. "Freud, of Vienna--you recall the name?--has
+done most, I think in that direction."
+
+I recalled something of the theories of the Freudists, but said
+nothing.
+
+"It is an unpleasant feature of his philosophy," he went on, "but
+Freud finds the conclusion irresistible that all humanity
+underneath the shell is sensuous and sensual in nature.
+Practically all dreams betray some delight of the senses and
+sexual dreams are a large proportion. There is, according to the
+theory, always a wish hidden or expressed in a dream. The dream is
+one of three things, the open, the disguised or the distorted
+fulfillment of a wish, sometimes recognized, sometimes repressed.
+
+"Anxiety dreams are among the most interesting and important
+Anxiety may originate in psycho-sexual excitement, the repressed
+libido, as the Freudists call it. Neurotic fear has its origin in
+sexual life and corresponds to a libido which has been turned away
+from its object and has not succeeded in being applied. All so-
+called day dreams of women are erotic; of men they are either
+ambition or love.
+
+"Often dreams, apparently harmless, turn out to be sinister if we
+take pains to interpret them. All have the mark of the beast. For
+example, there was that unknown woman who had fallen down and was
+surrounded by a crowd. If a woman dreams that, it is sexual. It
+can mean only a fallen woman. That is the symbolism. The crowd
+always denotes a secret.
+
+"Take also the dream of death. If there is no sorrow felt, then
+there is another cause for it. But if there is sorrow, then the
+dreamer really desires death or absence. I expect to have you
+quarrel with that. But read Freud, and remember that in childhood
+death is synonymous with being away. Thus for example, if a girl
+dreams that her mother is dead, perhaps it means only that she
+wishes her away so that she can enjoy some pleasure that her
+strict parent, by her presence, denies.
+
+"Then there was that dream about the baby in the water. That, I
+think, was a dream of birth. You see, I asked her practically to
+repeat the dreams because there were several gaps. At such points
+one usually finds first hesitation, then something that shows one
+of the main complexes. Perhaps the subject grows angry at the
+discovery.
+
+"Now, from the tangle of the dream thought, I find that she fears
+that her husband is too intimate with another woman, and that
+perhaps unconsciously she has turned to Dr. Maudsley for sympathy.
+Dr. Maudsley, as I said, is not only bearded, but somewhat of a
+social lion. He had called on her the day before. Of such stuff
+are all dream lions when there is no fear. But she shows that she
+has been guilty of no wrongdoing--she escaped, and felt relieved."
+
+"I'm glad of that," I put in. "I don't like these scandals. On the
+Star when I have to report them, I do it always under protest. I
+don't know what your psychanalysis is going to show in the end,
+but I for one have the greatest sympathy for that poor little
+woman in the big house alone, surrounded by and dependent on
+servants, while her husband is out collecting scandals."
+
+"Which suggests our next step," he said, turning the subject. "I
+hope that Butler has found out the retreat of Veronica Haversham."
+
+We discovered Miss Haversham at last at Dr. Klemm's sanitarium, up
+in the hills of Westchester County, a delightful place with a
+reputation for its rest cures. Dr. Klemm was an old friend of
+Kennedy's, having had some connection with the medical school at
+the University.
+
+She had gone up there rather suddenly, it seemed, to recuperate.
+At least that was what was given out, though there seemed to be
+much mystery about her, and she was taking no treatment as far as
+was known.
+
+"Who is her physician?" asked Kennedy of Dr. Klemm as we sat in
+his luxurious office.
+
+"A Dr. Maudsley of the city."
+
+Kennedy glanced quickly at me in time to check an exclamation.
+
+"I wonder if I could see her?"
+
+"Why, of course--if she is willing," replied Dr. Klemm.
+
+"I will have to have some excuse," ruminated Kennedy. "Tell her I
+am a specialist in nervous troubles from the city, have been
+visiting one of the other patients, anything."
+
+Dr. Klemm pulled down a switch on a large oblong oak box on his
+desk, asked for Miss Haversham, and waited a moment.
+
+"What is that?" I asked.
+
+"A vocaphone," replied Kennedy. "This sanitarium is quite up to
+date, Klemm."
+
+The doctor nodded and smiled. "Yes, Kennedy," he replied.
+"Communicating with every suite of rooms we have the vocaphone. I
+find it very convenient to have these microphones, as I suppose
+you would call them, catching your words without talking into them
+directly as you have to do in the telephone and then at the other
+end emitting the words without the use of an earpiece, from the
+box itself, as if from a megaphone horn. Miss Haversham, this is
+Dr. Klemm. There is a Dr. Kennedy here visiting another patient, a
+specialist from New York. He'd like very much to see you if you
+can spare a few minutes."
+
+"Tell him to come up." The voice seemed to come from the vocaphone
+as though she were in the room with us.
+
+Veronica Haversham was indeed wonderful, one of the leading
+figures in the night life of New York, a statuesque brunette of
+striking beauty, though I had heard of often ungovernable temper.
+Yet there was something strange about her face here. It seemed
+perhaps a little yellow, and I am sure that her nose had a
+peculiar look as if she were suffering from an incipient rhinitis.
+The pupils of her eyes were as fine as pin heads, her eyebrows
+were slightly elevated. Indeed, I felt that she had made no
+mistake in taking a rest if she would preserve the beauty which
+had made her popularity so meteoric.
+
+"Miss Haversham," began Kennedy, "they tell me that you are
+suffering from nervousness. Perhaps I can help you. At any rate it
+will do no harm to try. I know Dr. Maudsley well, and if he
+doesn't approve--well, you may throw the treatment into the waste
+basket."
+
+"I'm sure I have no reason to refuse," she said. "What would you
+suggest?"
+
+"Well, first of all, there is a very simple test I'd like to try.
+You won't find that it bothers you in the least--and if I can't
+help you, then no harm is done."
+
+Again I watched Kennedy as he tactfully went through the
+preparations for another kind of psychanalysis, placing Miss
+Haversham at her ease on a davenport in such a way that nothing
+would distract her attention. As she reclined against the leather
+pillows in the shadow it was not difficult to understand the lure
+by which she held together the little coterie of her intimates.
+One beautiful white arm, bare to the elbow, hung carelessly over
+the edge of the davenport, displaying a plain gold bracelet.
+
+"Now," began Kennedy, on whom I knew the charms of Miss Haversham
+produced a negative effect, although one would never have guessed
+it from his manner, "as I read off from this list of words, I wish
+that you would repeat the first thing, anything," he emphasized,
+"that comes into your head, no matter how trivial it may seem.
+Don't force yourself to think. Let your ideas flow naturally. It
+depends altogether on your paying attention to the words and
+answering as quickly as you can--remember, the first word that
+comes into your mind. It is easy to do. We'll call it a game," he
+reassured.
+
+Kennedy handed a copy of the list to me to record the answers.
+There must have been some fifty words, apparently senseless,
+chosen at random, it seemed. They were:
+
+
+ head to dance salt white lie
+
+ green sick new child to fear
+
+ water pride to pray sad stork
+
+ to sing ink money to marry false
+
+ death angry foolish dear anxiety
+
+ long needle despise to quarrel to kiss
+
+ ship voyage finger old bride
+
+ to pay to sin expensive family pure
+
+ window bread to fall friend ridicule
+
+ cold rich unjust luck to sleep
+
+
+"The Jung association word test is part of the Freud
+psychanalysis, also," he whispered to me, "You remember we tried
+something based on the same idea once before?"
+
+I nodded. I had heard of the thing in connection with blood-
+pressure tests, but not this way.
+
+Kennedy called out the first word, "Head," while in his hand he
+held a stop watch which registered to one-fifth of a second.
+
+Quickly she replied, "Ache," with an involuntary movement of her
+hand toward her beautiful forehead.
+
+"Good," exclaimed Kennedy. "You seem to grasp the idea better than
+most of my patients."
+
+I had recorded the answer, he the time, and we found out, I recall
+afterward, that the time averaged something like two and two-
+fifths seconds.
+
+I thought her reply to the second word, "green," was curious. It
+came quickly, "Envy."
+
+However, I shall not attempt to give all the replies, but merely
+some of the most significant. There did not seem to be any
+hesitation about most of the words, but whenever Kennedy tried to
+question her about a word that seemed to him interesting she made
+either evasive or hesitating answers, until it became evident that
+in the back of her head was some idea which she was repressing and
+concealing from us, something that she set off with a mental "No
+Thoroughfare."
+
+He had finished going through the list, and Kennedy was now
+studying over the answers and comparing the time records.
+
+"Now," he said at length, running his eye over the words again, "I
+want to repeat the performance. Try to remember and duplicate your
+first replies," he said.
+
+Again we went through what at first had seemed to me to be a
+solemn farce, but which I began to see was quite important.
+Sometimes she would repeat the answer exactly as before. At other
+times a new word would occur to her. Kennedy was keen to note all
+the differences in the two lists.
+
+One which I recall because the incident made an impression on me
+had to do with the trio, "Death--life--inevitable." "Why that?" he
+asked casually.
+
+"Haven't you ever heard the saying, 'One should let nothing which
+one can have escape, even if a little wrong is done; no
+opportunity should be missed; life is so short, death
+inevitable'?"
+
+There were several others which to Kennedy seemed more important,
+but long after we had finished I pondered this answer. Was that
+her philosophy of life? Undoubtedly she would never have
+remembered the phrase if it had not been so, at least in a
+measure.
+
+She had begun to show signs of weariness, and Kennedy quickly
+brought the conversation around to subjects of apparently a
+general nature, but skillfully contrived so as to lead the way
+along lines her answers had indicated.
+
+Kennedy had risen to go, still chatting. Almost unintentionally he
+picked up from a dressing table a bottle of white tablets, without
+a label, shaking it to emphasize an entirely, and I believe
+purposely, irrelevant remark.
+
+"By the way," he said, breaking off naturally, "what is that?"
+
+"Only something Dr. Maudsley had prescribed for me," she answered
+quickly.
+
+As he replaced the bottle and went on with the thread of the
+conversation, I saw that in shaking the bottle he had abstracted a
+couple of the tablets before she realized it. "I can't tell you
+just what to do without thinking the case over," he concluded,
+rising to go. "Yours is a peculiar case, Miss Haversham, baffling.
+I'll have to study it over, perhaps ask Dr. Maudsley If I may see
+you again. Meanwhile, I am sure what he is doing is the correct
+thing."
+
+Inasmuch as she had said nothing about what Dr. Maudsley was
+doing, I wondered whether there was not just a trace of suspicion
+in her glance at him from under her long dark lashes.
+
+"I can't see that you have done anything," she remarked pointedly.
+"But then doctors are queer--queer."
+
+That parting shot also had in it, for me, something to ponder
+over. In fact I began to wonder if she might not be a great deal
+more clever than even Kennedy gave her credit for being, whether
+she might not have submitted to his tests for pure love of pulling
+the wool over his eyes.
+
+Downstairs again, Kennedy paused only long enough to speak a few
+words with his friend Dr. Klemm.
+
+"I suppose you have no idea what Dr. Maudsley has prescribed for
+her?" he asked carelessly.
+
+"Nothing, as far as I know, except rest and simple food."
+
+He seemed to hesitate, then he said under his voice, "I suppose
+you know that she is a regular dope fiend, seasons her cigarettes
+with opium, and all that."
+
+"I guessed as much," remarked Kennedy, "but how does she get it
+here?"
+
+"She doesn't."
+
+"I see," remarked Craig, apparently weighing now the man before
+him. At length he seemed to decide to risk something.
+
+"Klemm," he said, "I wish you would do something for me. I see you
+have the vocaphone here. Now if--say Hazleton--should call--will
+you listen in on that vocaphone for me?" Dr. Klemm looked squarely
+at him.
+
+"Kennedy," he said, "it's unprofessional, but---"
+
+"So it is to let her be doped up under guise of a cure."
+
+"What?" he asked, startled. "She's getting the stuff now?"
+
+"No, I didn't say she was getting opium, or from anyone here. All
+the same, if you would just keep an ear open---"
+
+"It's unprofessional, but--you'd not ask it without a good reason.
+I'll try."
+
+It was very late when we got back to the city and we dined at an
+uptown restaurant which we had almost to ourselves.
+
+Kennedy had placed the little whitish tablets in a small paper
+packet for safe keeping. As we waited for our order he drew one
+from his pocket, and after looking at it a moment crushed it to a
+powder in the paper.
+
+"What is it?" I asked curiously. "Cocaine?"
+
+"No," he said, shaking his head doubtfully.
+
+He had tried to dissolve a little of the powder in some water from
+the glass before him, but it would not dissolve.
+
+As he continued to look at it his eye fell on the cut-glass
+vinegar cruet before us. It was full of the white vinegar.
+
+"Really acetic acid," he remarked, pouring out a little.
+
+The white powder dissolved.
+
+For several minutes he continued looking at the stuff.
+
+"That, I think," he remarked finally, "is heroin."
+
+"More 'happy dust'?" I replied with added interest now, thinking
+of our previous case. "Is the habit so extensive?"
+
+"Yes," he replied, "the habit is comparatively new, although in
+Paris, I believe, they call the drug fiends, 'heroinomaniacs.' It
+is, as I told you before, a derivative of morphine. Its scientific
+name is diacetyl-morphin. It is New York's newest peril, one of
+the most dangerous drugs yet. Thousands are slaves to it, although
+its sale is supposedly restricted. It is rotting the heart out of
+the Tenderloin. Did you notice Veronica Haversham's yellowish
+whiteness, her down-drawn mouth, elevated eyebrows, and contracted
+eyes? She may have taken it up to escape other drugs. Some people
+have--and have just got a new habit. It can be taken
+hypodermically, or in a tablet, or by powdering the tablet to a
+white crystalline powder and snuffing up the nose. That's the way
+she takes it. It produces rhinitis of the nasal passages, which I
+see you observed, but did not understand. It has a more profound
+effect than morphine, and is ten times as powerful as codeine. And
+one of the worst features is that so many people start with it,
+thinking it is as harmless as it has been advertised. I wouldn't
+be surprised if she used from seventy-five to a hundred one-
+twelfth grain tablets a day. Some of them do, you know."
+
+"And Dr. Maudsley," I asked quickly, "do you think it is through
+him or in spite of him?"
+
+"That's what I'd like to know. About those words," he continued,
+"what did you make of the list and the answers?"
+
+I had made nothing and said so, rather quickly.
+
+"Those," he explained, "were words selected and arranged to strike
+almost all the common complexes in analyzing and diagnosing. You'd
+think any intelligent person could give a fluent answer to them,
+perhaps a misleading answer. But try it yourself, Walter. You'll
+find you can't. You may start all right, but not all the words
+will be reacted to in the same time or with the same smoothness
+and ease. Yet, like the expressions of a dream, they often seem
+senseless. But they have a meaning as soon as they are
+'psychanalyzed.' All the mistakes in answering the second time,
+for example, have a reason, if we can only get at it. They are not
+arbitrary answers, but betray the inmost subconscious thoughts,
+those things marked, split off from consciousness and repressed
+into the unconscious. Associations, like dreams, never lie. You
+may try to conceal the emotions and unconscious actions, but you
+can't."
+
+I listened, fascinated by Kennedy's explanation.
+
+"Anyone can see that that woman has something on her mind besides
+the heroin habit. It may be that she is trying to shake the habit
+off in order to do it; it may be that she seeks relief from her
+thoughts by refuge in the habit; and it may be that some one has
+purposely caused her to contract this new habit in the guise of
+throwing off an old. The only way by which to find out is to study
+the case."
+
+He paused. He had me keenly on edge, but I knew that he was not
+yet in a position to answer his queries positively.
+
+"Now I found," he went on, "that the religious complexes were
+extremely few; as I expected the erotic were many. If you will
+look over the three lists you will find something queer about
+every such word as, 'child, 'to marry,' 'bride,' 'to lie,'
+'stork,' and so on. We're on the right track. That woman does know
+something about that child."
+
+"My eye catches the words 'to sin,' 'to fall,' 'pure,' and
+others," I remarked, glancing over the list.
+
+"Yes, there's something there, too. I got the hint for the drug
+from her hesitation over 'needle' and 'white.' But the main
+complex has to do with words relating to that child and to love.
+In short, I think we are going to find it to be the reverse of the
+rule of the French, that it will be a case of 'cherchez l'homme.'"
+
+Early the next day Kennedy, after a night of studying over the
+case, journeyed up to the sanitarium again. We found Dr. Klemm
+eager to meet us.
+
+"What is it?" asked Kennedy, equally eager.
+
+"I overheard some surprising things over the vocaphone," he
+hastened. "Hazleton called. Why, there must have been some wild
+orgies in that precious set of theirs, and, would you believe it,
+many of them seem to have been at what Dr. Maudsley calls his
+'stable studio,' a den he has fixed up artistically over his
+garage on a side street."
+
+"Indeed?"
+
+"I couldn't get it all, but I did hear her repeating over and over
+to Hazleton, 'Aren't you all mine? Aren't you all mine?' There
+must be some vague jealousy lurking in the heart of that ardent
+woman. I can't figure it out."
+
+"I'd like to see her again," remarked Kennedy. "Will you ask her
+if I may?"
+
+
+
+
+CHAPTER XXXVI
+
+THE ENDS OF JUSTICE
+
+
+A few minutes later we were in the sitting room of her suite. She
+received us rather ungraciously, I thought.
+
+"Do you feel any better?" asked Kennedy.
+
+"No," she replied curtly. "Excuse me for a moment. I wish to see
+that maid of mine. Clarisse!"
+
+She had hardly left the room when Kennedy was on his feet. The
+bottle of white tablets, nearly empty, was still on the table. I
+saw him take some very fine white powder and dust it quickly over
+the bottle. It seemed to adhere, and from his pocket he quickly
+drew a piece of what seemed to be specially prepared paper, laid
+it over the bottle where the powder adhered, fitting it over the
+curves. He withdrew it quickly, for outside we heard her light
+step, returning. I am sure she either saw or suspected that
+Kennedy had been touching the bottle of tablets, for there was a
+look of startled fear on her face.
+
+"Then you do not feel like continuing the tests we abandoned last
+night?" asked Kennedy, apparently not noticing her look.
+
+"No, I do not," she almost snapped. "You--you are detectives. Mrs.
+Hazleton has sent you."
+
+"Indeed, Mrs. Hazleton has not sent us," insisted Kennedy, never
+for an instant showing his surprise at her mention of the name.
+
+"You are. You can tell her, you can tell everybody. I'll tell--
+I'll tell myself. I won't wait. That child is mine--mine--not
+hers. Now--go!"
+
+Veronica Haversham on the stage never towered in a fit of passion
+as she did now in real life, as her ungovernable feelings broke
+forth tempestuously on us.
+
+I was astounded, bewildered at the revelation, the possibilities
+in those simple words, "The child is mine." For a moment I was
+stunned. Then as the full meaning dawned on me I wondered in a
+flood of consciousness whether it was true. Was it the product of
+her drug-disordered brain? Had her desperate love for Hazleton
+produced a hallucination?
+
+Kennedy, silent, saw that the case demanded quick action. I shall
+never forget the breathless ride down from the sanitarium to the
+Hazleton house on Riverside Drive.
+
+"Mrs. Hazleton," he cried, as we hurried in, "you will pardon me
+for this unceremonious intrusion, but it is most important. May I
+trouble you to place your fingers on this paper--so?"
+
+He held out to her a piece of the prepared paper. She looked at
+him once, then saw from his face that he was not to be questioned.
+Almost tremulously she did as he said, saying not a word. I
+wondered whether she knew the story of Veronica, or whether so far
+only hints of it had been brought to her.
+
+"Thank you," he said quickly. "Now, if I may see Morton?"
+
+It was the first time we had seen the baby about whom the rapidly
+thickening events were crowding. He was a perfect specimen of
+well-cared-for, scientific infant.
+
+Kennedy took the little chubby fingers playfully in his own. He
+seemed at once to win the child's confidence, though he may have
+violated scientific rules. One by one he pressed the little
+fingers on the paper, until little Morton crowed with delight as
+one little piggy after another "went to market." He had deserted
+thousands of dollars' worth of toys just to play with the simple
+piece of paper Kennedy had brought with him. As I looked at him, I
+thought of what Kennedy had said at the start. Perhaps this
+innocent child was not to be envied after all. I could hardly
+restrain my excitement over the astounding situation which had
+suddenly developed.
+
+"That will do," announced Kennedy finally, carelessly folding up
+the paper and slipping it into his pocket. "You must excuse me
+now."
+
+"You see," he explained on the way to the laboratory, "that powder
+adheres to fresh finger prints, taking all the gradations. Then
+the paper with its paraffine and glycerine coating takes off the
+powder."
+
+In the laboratory he buried himself in work, with microscope
+compasses, calipers, while I fumed impotently at the window.
+
+"Walter," he called suddenly, "get Dr. Maudsley on the telephone.
+Tell him to come immediately to the laboratory."
+
+Meanwhile Kennedy was busy arranging what he had discovered in
+logical order and putting on it the finishing touches.
+
+As Dr. Maudsley entered Kennedy greeted him and began by plunging
+directly into the case in answer to his rather discourteous
+inquiry as to why he had been so hastily summoned.
+
+"Dr. Maudsley," said Craig, "I have asked you to call alone
+because, while I am on the verge of discovering the truth in an
+important case affecting Morton Hazleton and his wife, I am
+frankly perplexed as to how to go ahead."
+
+The doctor seemed to shake with excitement as Kennedy proceeded.
+
+"Dr. Maudsley," Craig added, dropping his voice, "is Morton III
+the son of Millicent Hazleton or not? You were the physician in
+attendance on her at the birth. Is he?"
+
+Maudsley had been watching Kennedy furtively at first, but as he
+rapped out the words I thought the doctor's eyes would pop out of
+his head. Perspiration in great beads collected on his face.
+
+"P--professor K--Kennedy," he muttered, frantically rubbing his
+face and lower jaw as if to compose the agitation he could so ill
+conceal, "let me explain."
+
+"Yes, yes--go on," urged Kennedy.
+
+"Mrs. Hazleton's baby was born--dead. I knew how much she and the
+rest of the family had longed for an heir, how much it meant. And
+I--substituted for the dead child a newborn baby from the
+maternity hospital. It--it belonged to Veronica Haversham--then a
+poor chorus girl. I did not intend that she should ever know it. I
+intended that she should think her baby was dead. But in some way
+she found out. Since then she has become a famous beauty, has
+numbered among her friends even Hazleton himself. For nearly two
+years I have tried to keep her from divulging the secret. From
+time to time hints of it have leaked out. I knew that if Hazleton
+with his infatuation of her were to learn---" "And Mrs. Hazleton,
+has she been told?" interrupted Kennedy.
+
+"I have been trying to keep it from her as long as I can, but it
+has been difficult to keep Veronica from telling it. Hazleton
+himself was so wild over her. And she wanted her son as she---"
+
+"Maudsley," snapped out Kennedy, slapping down on the table the
+mass of prints and charts which he had hurriedly collected and was
+studying, "you lie! Morton is Millicent Hazleton's son. The whole
+story is blackmail. I knew it when she told me of her dreams and I
+suspected first some such devilish scheme as yours. Now I know it
+scientifically."
+
+He turned over the prints.
+
+"I suppose that study of these prints, Maudsley, will convey
+nothing to you. I know that it is usually stated that there are no
+two sets of finger prints in the world that are identical or that
+can be confused. Still, there are certain similarities of finger
+prints and other characteristics, and these similarities have
+recently been exhaustively studied by Bertilion, who has found
+that there are clear relationships sometimes between mother and
+child in these respects. If Solomon were alive, doctor, he would
+not now have to resort to the expedient to which he did when the
+two women disputed over the right to the living child. Modern
+science is now deciding by exact laboratory methods the same
+problem as he solved by his unique knowledge of feminine
+psychology.
+
+"I saw how this case was tending. Not a moment too soon, I said to
+myself, 'The hand of the child will tell.' By the very variations
+in unlike things, such as finger and palm prints, as tabulated and
+arranged by Bertillon after study in thousands of cases, by the
+very loops, whorls, arches and composites, I have proved my case.
+
+"The dominancy, not the identity, of heredity through the infinite
+varieties of finger markings is sometimes very striking. Unique
+patterns in a parent have been repeated with marvelous accuracy in
+the child. I knew that negative results might prove nothing in
+regard to parentage, a caution which it is important to observe.
+But I was prepared to meet even that.
+
+"I would have gone on into other studies, such as Tammasia's, of
+heredity in the veining of the back of the hands; I would have
+measured the hands, compared the relative proportion of the parts;
+I would have studied them under the X-ray as they are being
+studied to-day; I would have tried the Reichert blood crystal test
+which is being perfected now so that it will tell heredity itself.
+There is no scientific stone I would have left unturned until I
+had delved at the truth of this riddle. Fortunately it was not
+necessary. Simple finger prints have told me enough. And best of
+all, it has been in time to frustrate that devilish scheme you and
+Veronica Haversham have been slowly unfolding."
+
+Maudsley crumpled up, as it were, at Kennedy's denunciation. He
+seemed to shrink toward the door.
+
+"Yes," cried Kennedy, with extended forefinger, "you may go--for
+the present. Don't try to run away. You're watched from this
+moment on."
+
+Maudsley had retreated precipitately.
+
+I looked at Kennedy inquiringly. What to do? It was indeed a
+delicate situation, requiring the utmost care to handle. If the
+story had been told to Hazleton, what might he not have already
+done? He must be found first of all if we were to meet the
+conspiracy of these two.
+
+Kennedy reached quickly for the telephone. "There is one stream of
+scandal that can be dammed at its source," he remarked, calling a
+number. "Hello. Klemm's Sanitarium? I'd like to speak with Miss
+Haversham. What--gone? Disappeared? Escaped?"
+
+He hung up the receiver and looked at me blankly. I was
+speechless.
+
+A thousand ideas flew through our minds at once. Had she perceived
+the import of our last visit and was she now on her way to
+complete her plotted slander of Millicent Hazleton, though it
+pulled down on herself in the end the whole structure?
+
+Hastily Kennedy called Hazleton's home, Butler, and one after
+another of Hazleton's favorite clubs. It was not until noon that
+Butler himself found him and came with him, under protest, to the
+laboratory.
+
+"What is it--what have you found?" cried Butler, his lean form a-
+quiver with suppressed excitement.
+
+Briefly, one fact after another, sparing Hazleton nothing, Kennedy
+poured forth the story, how by hint and innuendo Maudsley had been
+working on Millicent, undermining her, little knowing that he had
+attacked in her a very tower of strength, how Veronica, infatuated
+by him, had infatuated him, had led him on step by step.
+
+Pale and agitated, with nerves unstrung by the life he had been
+leading, Hazleton listened. And as Kennedy hammered one fact after
+another home, he clenched his fists until the nails dug into his
+very palms.
+
+"The scoundrels," he ground out, as Kennedy finished by painting
+the picture of the brave little broken-hearted woman fighting off
+she knew not what, and the golden-haired, innocent baby stretching
+out his arms in glee at the very chance to prove that he was what
+he was. "The scoundrels--take me to Maudsley now. I must see
+Maudsley. Quick!"
+
+As we pulled up before the door of the reconstructed stable-
+studio, Kennedy jumped out. The door was unlocked. Up the broad
+flight of stairs, Hazleton went two at a time. We followed him
+closely.
+
+Lying on the divan in the room that had been the scene of so many
+orgies, locked in each other's arms, were two figures--Veronica
+Haversham and Dr. Maudsley.
+
+She must have gone there directly after our visit to Dr. Klemm's,
+must have been waiting for him when he returned with his story of
+the exposure to answer her fears of us as Mrs. Hazleton's
+detectives. In a frenzy of intoxication she must have flung her
+arms blindly about him in a last wild embrace.
+
+Hazleton looked, aghast.
+
+He leaned over and took her arm. Before he could frame the name,
+"Veronica!" he had recoiled.
+
+The two were cold and rigid.
+
+"An overdose of heroin this time," muttered Kennedy.
+
+My head was in a whirl.
+
+Hazleton stared blankly at the two figures abjectly lying before
+him, as the truth burned itself indelibly into his soul. He
+covered his face with his hands. And still he saw it all.
+
+Craig said nothing. He was content to let what he had shown work
+in the man's mind.
+
+"For the sake of--that baby--would she--would she forgive?" asked
+Hazleton, turning desperately toward Kennedy.
+
+Deliberately Kennedy faced him, not as scientist and millionaire,
+but as man and man.
+
+"From my psychanalysis," he said slowly, "I should say that it IS
+within your power, in time, to change those dreams."
+
+Hazleton grasped Kennedy's hand before he knew it.
+
+"Kennedy--home--quick. This is the first manful impulse I have had
+for two years. And, Jameson--you'll tone down that part of it in
+the newspapers that Junior--might read--when he grows up?"

+Project Gutenberg eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the US
+unless a copyright notice is included. Thus, we usually do not
+keep eBooks in compliance with any particular paper edition.
+
+We are now trying to release all our eBooks one year in advance
+of the official release dates, leaving time for better editing.
+Please be encouraged to tell us about any error or corrections,
+even years after the official publication date.
+
+Please note neither this listing nor its contents are final til
+midnight of the last day of the month of any such announcement.
+The official release date of all Project Gutenberg eBooks is at
+Midnight, Central Time, of the last day of the stated month. A
+preliminary version may often be posted for suggestion, comment
+and editing by those who wish to do so.
+
+Most people start at our Web sites at:

+
+These Web sites include award-winning information about Project
+Gutenberg, including how to donate, how to help produce our new
+eBooks, and how to subscribe to our email newsletter (free!).
+
+
+Those of you who want to download any eBook before announcement
+can get to them as follows, and just download by date. This is
+also a good way to get them instantly upon announcement, as the

+Information about Project Gutenberg (one page)
+
+We produce about two million dollars for each hour we work. The
+time it takes us, a rather conservative estimate, is fifty hours
+to get any eBook selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. Our
+projected audience is one hundred million readers. If the value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour in 2002 as we release over 100 new text
+files per month: 1240 more eBooks in 2001 for a total of 4000+
+We are already on our way to trying for 2000 more eBooks in 2002
+If they reach just 1-2% of the world's population then the total
+will reach over half a trillion eBooks given away by year's end.
+
+The Goal of Project Gutenberg is to Give Away 1 Trillion eBooks!
+This is ten thousand titles each to one hundred million readers,
+which is only about 4% of the present number of computer users.
