+THE FACE OF HATE</h2>
+
+<p>
+It was three o’clock in the morning. Along a deserted pavement of Riverside
+Drive strode briskly a young man whose square-set shoulders and erect poise
+suggested a military training. His coat, thrown carelessly open to the cold
+night wind, displayed an expanse of white indicative of evening dress. As he
+walked his heels clicked sharply on the concrete with the forceful firm tread
+of the type which does things quickly and decisively. The intense stillness of
+the early morning hours carried the sound in little staccato beats that could
+be heard blocks away. A few yards behind him, moving furtively and noiselessly,
+almost as if he had been shod with rubber, crept another figure, that of a
+stocky, broad-shouldered man, who despite his bulk and weight moved silently
+and swiftly through the night, a soft brown hat drawn low over his eyes as if
+he desired to avoid recognition.
+</p>
+
+<p>
+All at once the man ahead paused suddenly and stood looking out over the river.
+Between the Drive and the distance-dimmed lights of the Jersey shore there rose
+like great silhouettes the grim figures of several huge steel-clad battleships,
+their fighting-tops lost in the shadows of the opposite hills. Beside them,
+obscure, with no lights visible, lay the great transports that in a few hours,
+or in a few days—who knew—they would be convoying with their precious cargo of
+fighting men across the war-perilled Atlantic.
+</p>
+
+<p>
+It was on the forward deck of one of these great battleships that the eyes of
+the man ahead were riveted. His shadower, evidently much concerned in his
+actions, crept slowly and stealthily forward, approaching nearer and still
+nearer without being observed.
+</p>
+
+<p>
+A dim light became visible on the warship’s deck and then vanished. Still the
+man stood there watching, a puzzled, anxious look coming into his face. Quickly
+the light reappeared—two flashes, a pause, two flashes, a pause, and then a
+single flash. It was such a light as might have been made by a pocket torch, a
+feeble ray barely strong enough to carry to the adjacent shore, a light that if
+it had been flashed from some sheltered nook by the boat davits might not even
+have attracted the attention of the officer on the bridge nor of the ship’s
+watchmen. Manifestly it was a signal intended for the eyes of some one on
+shore.
+</p>
+
+<p>
+A muttered imprecation escaped the lips of the watcher on the Drive. He stood
+there, straining his eyes toward the ship as if expecting a following signal,
+then he turned and gazed aloft at the windows of the apartment houses lining
+the driveway to see if some answering signal flashed back.
+</p>
+
+<p>
+And in the shadow of the buildings, hardly ten feet away but half sheltered by
+a doorway, stood his sinister pursuer, motionless but alert.
+</p>
+
+<p>
+For perhaps a quarter of an hour they held their positions. At last the man who
+was being followed shrugged his shoulders impatiently and set off again down
+the Drive, from time to time turning his head to watch the spot from which the
+signal had been flashed. Behind him, as doggedly as ever and now a little
+closer, crept the man with the hat over his eyes.
+</p>
+
+<p>
+Regardless of the lateness of the hour, at a third-floor window of one of the
+great apartment houses lining the Drive sat a young girl in her nightrobe, with
+her two great black braids flung forward over her shoulders, about which she
+had placed for warmth’s sake a quilted negligee. Jane Strong was far too
+excited to sleep. An hour before she had come in from a wonderful party. The
+music still was playing mad tunes in her ears. The excitement, the coffee, the
+spirited tilts at arms with her many dancing partners had set her brain on
+fire. Sleep seemed impossible as yet.
+</p>
+
+<p>
+Looking out at the river—a favorite occupation of hers—the sight of the
+warships looming up through the darkness reminded her once more that nearly all
+of the men with whom she had been dancing had been in uniform, bringing into
+prominence in the jumble of ideas in her over-stimulated brain, almost as a new
+discovery, the fact that her country was really engaged in war, that the men,
+the very men whom she knew best, were most of them fighting, or soon going to
+fight in a foreign land. Suddenly she found herself vaguely wishing that there
+was something she might do, something for the war, something to help. Would it
+not be splendid, she thought, to go to France as a Red Cross nurse, to be over
+there in the middle of things, where something exciting was forever going on.
+Life—the only life she knew about, existence as the petted daughter of
+well-to-do parents in a big city—had, ever since the war had begun, seemed
+strangely flat and uninteresting. Parties, to be sure, were fun but hardly any
+one was giving parties this year. The Stantons had entertained only because
+their lieutenant son was going abroad soon, and they wished him to have a
+pleasant memory to carry with him. Most of the interesting men she knew already
+were gone, and now Jack Stanton was going. How she wished she could find some
+way of getting into the war herself.
+</p>
+
+<p>
+The sound of approaching footsteps caught her ear. Wondering who was abroad at
+that hour of the night she pushed up the window softly and looked out. In the
+distance she saw a man approaching, striding briskly toward her. As she stood
+idly watching him and wondering about him, suddenly she caught her breath. She
+had sighted the other figure behind, the man creeping stealthily after him.
+Nearer and nearer they came. In tense expectation she waited, sensing some
+unusual development. They had reached her block now. Almost directly under her
+window the man in advance paused to light a cigarette. His shadow paused, too,
+but some incautious movement on his part must have betrayed him.
+</p>
+
+<p>
+Match in hand, the man in advance stood stock-still, his whole figure taut,
+poised, alert, in an attitude of listening. All at once he wheeled about,
+discovering the man close behind him. He sprang at once for his pursuer. The
+latter took to his heels, dashing around the corner, the man whom he had been
+following now hot at his heels.
+</p>
+
+<p>
+All trembling with nervous excitement Jane leaned out the window to listen and
+watch. She could hear the running feet of both men just around the corner. What
+was happening? The running feet came to an abrupt stop. There was a
+half-smothered cry, a sharp thud, like a body striking the pavement, and then
+came silence. Puzzled, vaguely alarmed, a hundred questions came pouring into
+her brain and lingered there disturbingly. Why had one of these men been
+shadowing the other? Why had the pursuer suddenly become the pursued? Why had
+the running footsteps come to such an abrupt stop? What was the noise she had
+heard? What was happening around the corner? Her fears rapidly growing, she was
+on the point of arousing her family. But what excuse should she give? What
+could she tell them? After all she had merely seen two men run up the side
+street. More than likely they would only laugh at her, and she did not like
+being laughed at. Besides, Dad was always cross when suddenly awakened.
+Undecided what to do she stood at the window, peering into the night.
+</p>
+
+<p>
+Five minutes, ten minutes she stood there in tremulous perplexity. A sense of
+impending tragedy seemed to have laid hold of her. A black horror seized her
+and held her at the window. Something terrible, something tragic, she was sure
+must have happened. Mustering up her strength and trying to calm her fears she
+was about to put down the window when she heard footsteps once more
+approaching. Straining her ears to listen she discovered the sound was that of
+the steps of a man—one man—approaching from around the corner. As she watched
+he turned into the Drive and came on toward her. She shrank back a little,
+fearful of being seen even though her room was in darkness. It was the first
+man. She recognized him at once by his top-hat and his evening clothes. He was
+walking even more briskly than before, almost running. There was no sign
+anywhere of the shorter thick-set man who had been following him. Something in
+the appearance of the figure in the street below struck her all at once as
+vaguely familiar. She wondered if it could be any one she knew.
+</p>
+
+<p>
+Presently he came directly opposite the light on the other side of the Drive so
+that it shone for an instant full on his face. Jane looked and shuddered. Never
+in all her life had she seen any man’s countenance so convulsed, not with pain,
+but with a soul-terrifying expression of hate, of virulent, murderous hate.
+</p>
+
+<p>
+Distorted though the man’s face was with such bitter frightfulness, she
+recognized him, not as any one she knew, but merely as one of the tenants in
+the same apartment building.
+</p>
+
+<p>
+“It’s one of the people next door,” she said to herself and in verification of
+her identification, as he approached the building, the young man cast a swift
+glance over his shoulder, and then, as if satisfied that he was unobserved,
+dashed hurriedly in at the entrance.
+</p>
+
+<p>
+Jane, more than ever wrought up with fear and dread of she knew not what,
+sprang hastily into bed and drew the covers about her shoulders. As yet she did
+not lie down but shiveringly waited. Presently she heard the elevator stop. She
+heard the key opening the door of the next apartment. In a few minutes she
+heard the man moving about his bedroom, separated from her own room by a mere
+six inches of plaster and paper, or whatever it is that apartment-house walls
+are made of.
+</p>
+
+<p>
+What could have happened? She was certain that something terrible had occurred
+in which the young man next door had played a tragic, perhaps even a criminal
+part. She tried in vain to conjecture what circumstance could have been
+responsible for the look of hatred she had seen on his face. She wondered what
+had been the fate of the man who had been following him. Had they quarrelled
+and fought? What could have been the subject of their quarrel?
+</p>
+
+<p>
+She tried to summarize what she knew about the people next door, and was amazed
+to discover how little she had to draw upon. As in most New York apartment
+houses so in Jane’s home all the tenants were utter strangers to each other,
+one family not even knowing the names of any of the others. Occasionally, to be
+sure, one rather resentfully rode up or down in the elevator with some of the
+other tenants but always without noticing or speaking to them. Jane’s family
+had been living in the building for five years, and of the twenty other
+families they knew the names of only two, having learned them by accident
+rather than intention. About the people next door Jane now discovered that she
+really knew nothing at all. There was a man with a gray beard who never took
+off his hat in the elevator, and there was the handsome young chap whom she had
+just seen entering. But what their names were, or their business, or how long
+they had lived there, or whether they were father and son, what servants they
+kept, or whether either or both of them was married—these were questions she
+could have answered as readily as if they had been living in Dallas, Texas, or
+Seattle, Washington, as in the next apartment. Quickly she found that she
+really knew nothing at all about them except—she could not recall that any one
+had told her or how she had got the impression—she was almost certain they were
+some sort of foreigners.
+</p>
+
+<p>
+Just when it was that her troubled thoughts were succeeded by even more
+troubled dreams she was not aware, but it was noon the next day when she was
+awakened by the maid bringing in her breakfast tray.
+</p>
+
+<p>
+“Terrible, Miss Jane, wasn’t it,” said the servant, “about that suicide last
+night, almost under our noses, you might say.”
+</p>
+
+<p>
+“Suicide!” cried the girl, at once wide-awake and interested “What suicide?”
+</p>
+
+<p>
+“A man was found dead in the side street right by our building with a revolver
+in his hand.”
+</p>
+
+<p>
+“What sort of a looking man was he?”
+</p>
+
+<p>
+“I didn’t see him,” said the maid, almost regretfully. “He was taken away
+before I was up. Cook tells me it was the milkman found him and notified the
+police.”
+</p>
+
+<p>
+“Who was he?”
+</p>
+
+<p>
+“Nobody round here knows a thing about him. He shot himself through the heart
+and us sleeping here an’ not knowing anything at all about it.”
+</p>
+
+<p>
+“But didn’t any one know who he was?”
+</p>
+
+<p>
+“Never a soul. The superintendents from all the buildings round took a look at
+the body, but none of them knew him. It wasn’t anybody that lived around here.
+There’s a piece in the afternoon papers about it.”
+</p>
+
+<p>
+“Get me a paper at once,” directed the girl.
+</p>
+
+<p>
+Eagerly she read the paragraph the maid pointed out. It really told very
+little. The body of a plainly dressed man had been found on the sidewalk. There
+was a revolver in his hand with one cartridge discharged, and the bullet had
+penetrated his heart. He had been a short stalky man and had worn a brown soft
+hat. There was nothing about his clothing to identify him, even the marks where
+his suit had been purchased having been removed. He had not been identified.
+The police and the coroner were satisfied that it was a case of suicide.
+</p>
+
+<p>
+Suicide!
+</p>
+
+<p>
+Jane, reading and rereading the paragraph, recalled the unusual occurrence she
+had witnessed the night before. Vividly there stood out before her the strange
+panorama she had seen, the tall young man in evening clothes, and the short
+stalky man with the soft hat who had followed him. The two of them had run
+around the corner. Only one of them had come back. Unforgettably there was
+imprinted in her memory the satanic expression on the young man’s face as he
+had hastened into the house. No wonder he had cast such an anxious glance
+behind him as he entered.
+</p>
+
+<p>
+Suicide!
+</p>
+
+<p>
+Jane was certain that it was no suicide. She remembered the curious thud she
+had heard from around the corner, like a body falling to the pavement. She
+recalled that it must have been at least ten minutes before the other man
+reappeared, time enough to have placed the revolver in the dead man’s hand,
+time enough even to have removed all possible means of identification from the
+man’s clothing.

+</div>
+
+<p>
+It was not suicide, Jane felt certain. It was murder! Slowly but oppressingly,
+overwhelmingly, it dawned on her not only that in all probability a murder had
+been committed, but also that she—more than likely, she alone in all the
+world—knew who the murderer was, who it must have been—the young man next door.

+THE ADDRESS ON THE CARD</h2>
+
+<p>
+Impatiently Jane looked at her wrist watch. It lacked an hour of the time when
+she was to meet her mother at the Ritz for tea. Her nerves still all ajangle
+from excitement and worry over the morning’s tragedy, and her own accidental
+secret knowledge of certain aspects of the case had made it wholly impossible
+for her to do anything that day with even simulated interest.
+</p>
+
+<p>
+She had been debating with herself whether or not to confide to her mother the
+story of the tragic tableau of which she had been an accidental witness, when
+Mrs. Strong had dashed into her bedroom to give her a hurried peck on the cheek
+and to say that she was off to luncheon and the matin&eacute;e with Mrs.
+Starrett.
+</p>
+
+<p>
+“You’re not looking well to-day, dear,” her mother had said. “Stay in bed and
+rest and join us for tea if you like.”
+</p>
+
+<p>
+Before she had opportunity to tell what she had seen, her mother was gone, but
+Jane had found it impossible to obey her well-meant injunction. She rose and
+dressed, her mind busy all the while with the problem of what her duty was. As
+she donned her clothing she paused from time to time to listen for sounds from
+the next apartment.
+</p>
+
+<p>
+What was her neighbor doing now? Had he read of the discovery of the man’s body
+in the street? Perhaps he had fled already? Not a sound was to be heard there.
+He did not look in the least like what Jane imagined a murderer would, yet
+certainly the circumstances pointed all too plainly to his guilt. She had seen
+two men dash around the corner, one in pursuit of the other. One of them had
+come back alone. Not long afterward a body—the body of the other man—had been
+found with a bullet in his heart. It must have been a murder.
+</p>
+
+<p>
+What ought she to do about it? Was it her duty to tell her mother and Dad about
+what she had seen? Mother, she knew, would be horrified and would caution her
+to say nothing to any one, but Dad was different. He had strict ideas about
+right and justice. He would insist on hearing every word she had to tell. More
+than likely he would decide that it was her duty to give the information to the
+authorities. Her face blanched at the thought. She could not do that. She
+pictured to herself the notoriety that would necessarily ensue. She saw herself
+being hounded by reporters, she imagined her picture in the papers, she heard
+herself branded as “the witness in that murder case,” she depicted herself
+being questioned by detectives and badgered by lawyers.
+</p>
+
+<p>
+No, she decided, it would be best for her never to tell a soul, not even her
+parents. In persistent silence lay her safest course. After all she had not
+witnessed the commission of the crime. She was not even sure that the man found
+dead had been one of the two she had watched from her window. If she saw the
+body she would not be able to identify it. She was not even certain in her own
+mind that the man next door had done the shooting, however suspicious his
+actions may have appeared to her. Besides, he did not look in the least like a
+murderer. He was too well-dressed.
+</p>
+
+<p>
+In an effort to put the whole thing out of her mind she tried to read, but was
+unable to keep her thoughts from wandering. She sat down at the piano, but
+music failed to interest or soothe her. She mussed over some unanswered notes
+in her desk but could not summon up enough concentration of mind to answer
+them. Restless and fidgety, unable to keep her thoughts from the unusual
+occurrences that had disturbed her ordinarily too peaceful life, she decided to
+take a walk until it was time to keep her appointment. Something—force of habit
+probably—led her to the shopping district. With still half an hour to kill, she
+went into a little specialty shop to examine some knitting bags displayed in
+the window.
+</p>
+
+<p>
+“Why don’t you knit as all the other girls are doing?” was her father’s
+constant suggestion every time she asserted her desire to be doing something in
+the war.
+</p>
+
+<p>
+“There’s no thrill in knitting,” she would answer. “Fix it, Dad, so that I can
+go to France as a Red Cross nurse or as an ambulance driver, won’t you? I want
+some excitement.”
+</p>
+
+<p>
+Always he had refused to consent to her going, insisting that France in wartime
+was no place for an untrained girl.
+</p>
+
+<p>
+“If I can’t go myself, I certainly am not going to send any knitting,” she
+would spiritedly answer, but several times recently the sight of such charming
+looking knitting bags had tempted her into almost breaking her resolution.
+</p>
+
+<p>
+Inside the shop she found nothing that appealed to her, and contented herself
+with buying some toilet articles. As she made her purchases she noticed, almost
+subconsciously, a man standing near, talking with one of the shopgirls—a
+middle-aged man with a dark mustache.
+</p>
+
+<p>
+“The address, please,” said the girl, who had been waiting on her.
+</p>
+
+<p>
+“Miss Strong,” she answered, giving the number of the apartment house on
+Riverside Drive.
+</p>
+
+<p>
+She recalled afterward that as she mentioned the number the man standing there
+had turned and looked sharply at her, but she thought nothing of it. Her
+father’s name was well known and he had many acquaintances in the city. More
+than likely, she supposed, this man was some friend of her father who had
+recognized the name.
+</p>
+
+<p>
+She lingered a few moments at some of the other counters, aimlessly inspecting
+their offerings, and at last, with ten minutes left to reach the Ritz, emerged
+from the store. She was amazed to see the man who had been inside now standing
+near the entrance, and something within warned her that he had been waiting to
+speak to her. As she attempted to pass him quickly, he stepped in front of her,
+blocking her path, but raising his hat deferentially.
+</p>
+
+<p>
+“I beg your pardon, Miss Strong,” he said, “may I have a word with you?”
+</p>
+
+<p>
+Compelled to halt, she looked at him both appraisingly and resentfully. There
+was nothing offensive nor flirtatious in his manner, and he seemed far too
+respectably dressed to be a beggar. He was almost old enough to be her father,
+and besides there was about him an indefinable air of authority that commanded
+her attention. She decided that, unusual as his request appeared, she would
+hear what he had to say.
+</p>
+
+<p>
+“What is it?” she asked, trying to assume an air of hauteur but without being
+able wholly to mask her curiosity.
+</p>
+
+<p>
+“You are an American, aren’t you?” he asked abruptly.
+</p>
+
+<p>
+“Of course.”
+</p>
+
+<p>
+“A good American?”
+</p>
+
+<p>
+“I hope so.” She decided now that he must be one of the members of some Red
+Cross fund “drive,” or perhaps an overenthusiastic salesman for government
+bonds. “But I don’t quite understand what it is that you wish.”
+</p>
+
+<p>
+“I can’t explain,” said her questioner, “but if you really are a good American
+and you’d like to do your country a great service—an important service—go at
+once to the address on this card.”
+</p>
+
+<p>
+She took the slip of white pasteboard handed her. On it was written in pencil
+“Room 708.” The building was a skyscraper down-town.
+</p>
+
+<p>
+“What is it?” she asked half indignantly, “a new scheme to sell bonds?”
+</p>
+
+<p>
+“No, no, Miss Strong,” he cried, “it is nothing like that. It is a great
+opportunity to do an important service for America.”
+</p>
+
+<p>
+“How did you know my name?”
+</p>
+
+<p>
+“I heard you give it to the clerk just now.”
+</p>
+
+<p>
+“And why,” she inquired with what she intended to be withering sarcasm, “have I
+been selected so suddenly for this important work?”
+</p>
+
+<p>
+“I heard the address you gave, that’s why,” he answered. “That’s what makes it
+so important that you should go to that number at once. Ask for Mr. Fleck.”
+</p>
+
+<p>
+“I can’t go,” she temporized. “I am on my way now to meet my mother at the
+Ritz.”
+</p>
+
+<p>
+“Go to-morrow, then,” he insisted. “I’ll see Mr. Fleck meanwhile and tell him
+about you.”
+</p>
+
+<p>
+Puzzled at the man’s unusual and wholly preposterous request, yet in spite of
+herself impressed by his evident sincerity, Jane turned the card nervously in
+her hand and discovered some small characters on the back; “K-15” they read.
+</p>
+
+<p>
+“What do those figures mean?” she asked.
+</p>
+
+<p>
+“I can’t tell you that. Mr. Fleck will explain everything. Promise me you will
+go to see him.”
+</p>
+
+<p>
+“Who are you?”
+</p>
+
+<p>
+“I can’t tell you that, yet.”
+</p>
+
+<p>
+“Who, then, is Mr. Fleck?”
+</p>
+
+<p>
+“He will explain that to you.”
+</p>
+
+<p>
+“What has my address to do with it? I can’t understand yet why you make this
+preposterous request of me.”
+</p>
+
+<p>
+“I tell you I can’t explain it to you, not yet,” the man replied, “but it’s
+because you live where you do you must go to see Mr. Fleck. It’s about a matter
+of the highest importance to your government. It is more important than life
+and death.”
+</p>
+
+<p>
+His last words startled her. They brought to her mind afresh the mysterious
+occurrence she had witnessed the night before and the equally mysterious death
+near her home. Had this man’s odd request any connection, she wondered, with
+what had happened there? The lure of the unknown, the opportunity for
+adventure, called to her, though prudence bade her be cautious.
+</p>
+
+<p>
+“I’ll ask my mother,” she temporized.
+</p>
+
+<p>
+“Don’t,” cried the man. “You must keep your visit to Mr. Fleck a secret from
+everybody. You mustn’t breathe a word about it even to your father and mother.
+Take my word for it, Miss Strong, that what I am asking you to do is right.
+I’ve two daughters of my own. The thing I’m urging you to do I’d be proud and
+honored to have either of them do if they could. There is no one else in the
+world but you that can do this particular thing. A word to a single living soul
+and you’ll end your usefulness. You must not even tell any one you have talked
+with me. See Mr. Fleck. He’ll explain everything to you. Promise me you’ll see
+him.”
+</p>
+
+<p>
+“I promise,” Jane found herself saying, even against her better judgment, won
+over by the man’s insistence.
+</p>
+
+<p>
+“Good. I knew you would,” said her mysterious questioner, turning on his heel
+and vanishing speedily as if afraid to give her an opportunity of
+reconsidering.
+</p>
+
+<p>
+Puzzled beyond measure not only at the man’s strange conduct but even more at
+her own compliance with his request, Jane made her way slowly and thoughtfully
+to the Ritz, where she found her mother and Mrs. Starrett had already arrived.
+</p>
+
+<p>
+As they sipped their tea the two elder women chatted complacently about the
+matin&eacute;e, about their acquaintances, about other women in the tea-room
+and the gowns they had on, about bridge hands—the usual small talk of afternoon
+tea.
+</p>
+
+<p>
+To Jane, oppressed with her two secrets, all at once their conversation seemed
+the dreariest piffle. Great things were happening everywhere in the world,
+nations at war, men fighting and dying in the trenches of horror for the sake
+of an ideal, kings were being overthrown, dynasties tottering, boundaries of
+nations vanishing. Women, she realized, too, more than ever in history, were
+taking an active and important part in world affairs. In the lands of battle
+they were nursing the wounded, driving ambulances, helping to rehabilitate
+wrecked villages. In the lands where peace still reigned they were voting,
+speech-making, holding jobs, running offices, many of them were uniting to aid
+in movements for civic improvement, for better children, for the improvement of
+the whole human race.
+</p>
+
+<p>
+And here they were—here <i>she</i> was, idling uselessly at the Ritz as she had
+done yesterday, last week, last month—forever, it seemed to her. The vague
+protest that for some time had been growing within her against the
+senselessness and futility of her manner of existence crystallized itself now
+into a determination no longer to submit to it. Courageously she was resolving
+that she would take the first opportunity to escape from this boresome routine
+of pleasure-seeking. She was wondering if the request that had been so
+unexpectedly made of her would prove to be her way out from her prison of
+desuetude.
+</p>
+
+<p>
+The talk of the two women with her drifted aimlessly on. Seldom was she
+included in it, save when her mother, nodding to some one she knew, would turn
+to say:
+</p>
+
+<p>
+“Daughter, there is Mrs. Jones-Lloyd.”
+</p>
+
+<p>
+What did she care about Mrs. Jones-Lloyd? What did she care about any of the
+people about them, aimless, pleasure-hunting drifters like themselves. Left to
+her own devices for mental activity her thoughts kept recurring to the
+surprising adventure she had had a few minutes before. Thoughtfully she
+pondered over the mysterious message that had been given to her. The man had
+said that it was a wonderful opportunity for her to do her country a great
+service. She wondered why he had been so secretive about it. She decided that
+she would investigate further and made up her mind to carry out his
+instructions. What harm could befall her in visiting an office building in the
+business district? At least it would be something to do, something new,
+something different, something surely exciting and, perhaps, something useful.
+</p>
+
+<p>
+It would be better, she decided, for the present at least, to keep her
+intentions entirely to herself. Any hint of her plans to her mother would
+surely result in permission being refused. The man certainly had seemed
+sincere, honest, and perfectly respectable, even if he was not of the sort one
+would ask to dinner. She made up her mind to go down-town to the address given
+the very first thing to-morrow morning. If anything should happen to her, she
+felt that she could always reach her father. His office was in the next block.
+</p>
+
+<p>
+The problem of making the mysterious journey without her mother’s knowledge
+bothered her not at all. As in the case of most apartment-house families, she
+and her mother really saw very little of each other, especially since she had
+become a “young lady.” Mrs. Strong went constantly to lectures, to luncheons,
+to bridge parties, to matin&eacute;es with her own particular friends. Jane’s
+engagements were with another set entirely, school friends most of them, whose
+parents and hers hardly knew each other. Both she and her mother habitually
+breakfasted in bed, generally at different hours, and seldom lunched together.
+At dinner, when Mr. Strong was present, there were no intimacies between mother
+and daughter. The only times they really saw each other for protracted periods
+were when they happened to go shopping, or go to the dressmaker’s together, and
+then the subject always uppermost in the minds of both of them was the
+all-important and absorbing topic of clothes. Occasionally, Jane poured at one
+of her mother’s more formal functions, but for the most part the time of each
+was taken up in a mad, senseless hunt for amusement.
+</p>
+
+<p>
+Suddenly every thought was driven from Jane’s head. Her face went white, and
+with difficulty she managed to suppress an alarmed cry.
+</p>
+
+<p>
+“What is it, daughter?” asked her mother, noting her perturbation. “Are you
+feeling ill?”
+</p>
+
+<p>
+“A touch of neuralgia,” she managed to answer.
+</p>
+
+<p>
+“Too many late hours,” warned Mrs. Starrett reprovingly.
+</p>
+
+<p>
+“I’m afraid so,” said Mrs. Strong. “As soon as I’ve paid my check we’ll go.”
+</p>
+
+<p>
+“I’m perfectly all right now,” said Jane, controlling herself with effort,
+though her face was still white.
+</p>
+
+<p>
+The danger that she had feared had passed for the present at least. Glancing
+toward the entrance a moment before she had been terrified to see entering the
+black-mustached man who had accosted her a few moments before. Her one thought
+now had been that he had followed her here, and in a panic she was wondering
+how she should make explanations if he came up to their table and spoke. To her
+great relief he gave no intimation of having seen her, but settled himself into
+a chair near the door where he was half hidden from her by a great palm.
+Furtively she watched him, trying to divine his intention in having followed
+her there. Respectable enough though he was in appearance and garb, he did not
+seem in the least like the sort of man likely to be found at tea-time in an
+exclusive hotel. As she studied him she soon saw that his attention seemed to
+be riveted on some one sitting at the other side of the room. Wonderingly she
+let her eyes follow his, and once more it was with difficulty that she
+suppressed an excited gasp.
+</p>
+
+<p>
+There, across the room, calmly sipping some coffee, was the handsome young man
+from the next apartment—the man whom she had felt sure, or at least almost
+sure, was a murderer, about whom she had been wondering all day long, picturing
+him as a hunted criminal fleeing from the law. Chatting interestedly with him
+was another man, a young man in the uniform of a lieutenant in the navy.
+</p>
+
+<p>
+What did it all mean? Why was the black-mustached man watching them so
+intently? Her eyes turned back to him. He was still sitting there, leaning
+forward a little, his brows in a pucker of concentration, his eyes still fixed
+on the pair opposite. It looked almost as if he was trying to read their lips
+and tell what they were talking about.
+</p>
+
+<p>
+Jane thrilled with excitement. The black-mustached man, she decided, must be a
+detective. She recalled that he had said to her it was because she lived at the
+address she did that she was available for the mission for which he wanted her.
+Did he, she wondered, know about the mysterious death in the street outside
+their apartment house? Was that the reason he was spying on her neighbor? But
+what could be his motive in seeking to involve her in the matter?
+</p>
+
+<p>
+Unable to find satisfactory answers to her questions she gave herself up
+interestedly to studying the faces of the two young men across the room.
+Neither of them, she decided, could be much more than thirty. The face that
+only a few hours before she had seen utterly convulsed with bitter hate, now
+placid and smiling, was really an attractive one, not in the least like a
+murderer’s. Frank, alert blue eyes looked out from under an intellectual
+forehead. A small military mustache lent emphasis to a clean-shaven, forceful
+jaw. His flaxen hair was neatly trimmed. His linen and clothing were
+immaculate, and the hand that curved around his cup had long, tapering,
+well-manicured fingers. The cut of his clothing, his manners, everything about
+him seemed American, yet there was an indefinable something in his appearance
+that suggested foreign birth or parentage, probably either Swedish or German.
+The man with him was smaller and slighter. Despite the air of importance his
+uniform gave him, it was palpable that he was the less forceful of the two, his
+handsome face, it seemed to Jane, betraying weakness of character and a
+fondness for the good things of life.
+</p>
+
+<p>
+“Come, daughter,” said Mrs. Strong, rising, “we must be going.”
+</p>
+
+<p>
+So intent was Jane on her study of the two men that her mother had to speak
+twice to her.
+</p>
+
+<p>
+“Yes, mother,” she answered obediently, rising hastily as the hint of annoyance
+in her mother’s repeated remark brought her to a realization of having been
+addressed.
+</p>
+
+<p>
+Letting her mother and Mrs. Starrett precede her in the doorway she paused to
+look back at the scene that had interested her so strongly. What <i>could</i>
+it mean? What was going on? How was she involved in it?
+</p>
+
+<p>
+Her glance moved quickly from the watcher to the watched. The blond young man
+caught her eye. Amazedly, it seemed to her, he stopped right in the middle of
+what he was saying and sat there, his gaze fixed full on her. She let her eyes
+fall, abashed, and turned to hasten after her mother, but not so quickly did
+she turn but that she observed he had hastily seized his cup and appeared to be
+drinking to her, not so much impudently as admiringly.

+<h2><a name="CHAPTER_III"></a>CHAPTER III<br/>
+“MR. FLECK”</h2>
+
+<p>
+Twice after the elevator had deposited her on the floor Jane had approached the
+door of Room 708, and twice she had walked timorously past it to the end of the
+hall, trying to muster up courage to enter. A visit to a man’s office in the
+business district was a novelty for her. On the few previous excursions of the
+sort she had made she always had been accompanied by one of her parents. She
+found herself wishing now that she had taken her father into her confidence and
+had asked him to go with her. Making shopping her excuse she had come down-town
+with Mr. Strong but had gotten off at Astor Place, and waited over for another
+train.
+</p>
+
+<p>
+In her hand she held the card given to her by the black-mustached man the
+afternoon before. As she studied it now her curiosity came to the rescue of her
+fast-oozing courage. She must find out what it all meant, whatever the risk or
+peril that might confront her. Boldly she returned to Room 708 and opened the
+door. An office boy seated at a desk looked up inquiringly.
+</p>
+
+<p>
+“Is Mr. Fleck in?” she inquired timidly.
+</p>
+
+<p>
+“Who wishes to see him?”
+</p>
+
+<p>
+“Just say there’s a lady wishes to speak to him,” she faltered, hesitating to
+give her name.
+</p>
+
+<p>
+“Are you Miss Strong?” asked the boy abruptly, “because if you are, he’s
+expecting you.”
+</p>
+
+<p>
+She nodded, and the boy, jumping up, escorted her into an inner room. As she
+entered nervously an alert-looking man, with graying hair and mustache, rose
+courteously to greet her. In the quick glance she gave at her surroundings she
+was conscious only of the great mahogany desk at which he sat and behind it
+some filing cabinets and a huge safe, the outer doors of which stood open.
+</p>
+
+<p>
+“Sit down, won’t you, Miss Strong,” he said, placing a chair for her.
+</p>
+
+<p>
+His manner and his cultured tone, everything about him, reassured her at once.
+They conveyed to her that he was what she would have termed “a gentleman,” and
+with a little sigh of relief she seated herself.
+</p>
+
+<p>
+“I’m afraid,” said Mr. Fleck, smiling, “that Carter’s method of approaching you
+must have alarmed you.”
+</p>
+
+<p>
+“Carter—Oh, the black-mustached man.”
+</p>
+
+<p>
+“Yes, that describes him. You see, he did not wish to act definitely without
+consulting his chief, yet the unexpected opportunity seemed far too vital not
+to be utilized. He did not explain, did he, what it was we wanted of you?”
+</p>
+
+<p>
+“Indeed he didn’t,” said Jane, now wholly herself. “He was most mysterious
+about it.”
+</p>
+
+<p>
+Mr. Fleck smiled amusedly.
+</p>
+
+<p>
+“Carter has been an agent so long that being mysterious is second nature to
+him.”
+</p>
+
+<p>
+“An agent—I don’t understand.”
+</p>
+
+<p>
+“A Department agent,” explained Mr. Fleck, adding, “engaged in secret service
+work for the government.”
+</p>
+
+<p>
+“Oh!”
+</p>
+
+<p>
+Jane’s exclamation was not so much of surprise as of delighted realization, and
+the satisfaction expressed in her face was by no means lost on Mr. Fleck.
+</p>
+
+<p>
+“Would you object,” he asked, moving his chair a little closer to hers, “if,
+before I explain why you are here, I ask you a few questions—very personal
+questions?”
+</p>
+
+<p>
+“Certainly not,” said Jane.
+</p>
+
+<p>
+“You are American-born, of course?”
+</p>
+
+<p>
+“Oh, yes.”
+</p>
+
+<p>
+“And your parents?”
+</p>
+
+<p>
+“American for ten or twelve generations.”
+</p>
+
+<p>
+“How long have you lived in that apartment house on Riverside Drive?”
+</p>
+
+<p>
+“For about five years.”
+</p>
+
+<p>
+“Do you know any of the other tenants in the house?”
+</p>
+
+<p>
+“No—that is, none personally.”
+</p>
+
+<p>
+“Is your time fully occupied?”
+</p>
+
+<p>
+“No, indeed it isn’t, I’ve nothing to do at all, nothing except to try to amuse
+myself.”
+</p>
+
+<p>
+“Good,” said Mr. Fleck. “Now would you be willing to help in some secret work
+for the United States Government, some work of the very highest importance?”
+</p>
+
+<p>
+“Would I?” cried Jane, her eyes shining. “Gladly! Just try me.”
+</p>
+
+<p>
+“Don’t answer too quickly,” warned Mr. Fleck. “Remember, it will be real work,
+serious work, not always pleasant, sometimes possibly a little perilous.
+Remember, too, it must be done with absolute secrecy. You must not let even
+your parents know that you are working with us. You must pledge yourself to
+breathe no word of what you are doing or are asked to do to a living soul.
+Everything that we may tell you is to be buried forever from everybody. No one
+is to be trusted. The minute one other person knows your secret it will no
+longer be a secret. Can we depend upon you?”
+</p>
+
+<p>
+“You may absolutely depend on me,” said Jane slowly and soberly. “I give you my
+word. I have been eager for ever so long to do something to help, to really
+help. My father is doing all he can to aid the government. He’s on the Shipping
+Board.”
+</p>
+
+<p>
+Mr. Fleck nodded. Evidently he was aware of it already.
+</p>
+
+<p>
+“My brother, my only brother,” Jane continued, with a little catch in her
+throat, “is Over There—somewhere Over There—fighting for his government. If
+there is anything I can do to help the country he is fighting for, the country
+he may die for, I pledge you I will do it gladly with my heart, my soul, my
+body—everything.”
+</p>
+
+<p>
+“Thank you,” said Mr. Fleck softly, taking her hand. “I felt sure you were that
+sort of a girl. Now listen.” He moved his chair still closer to hers, and his
+voice became almost a whisper. “In the apartment next to you there live two
+men,—Otto Hoff and his nephew, Fred. They have an old German servant, but we
+can leave her out of it for the present. The old man is a lace importer.
+Apparently they are both above suspicion, yet—”
+</p>
+
+<p>
+He stopped abruptly.
+</p>
+
+<p>
+“You think they are spies—spies for Germany,” questioned Jane excitedly.
+“They’re Germans, of course?”
+</p>
+
+<p>
+“Otto Hoff is German-born, but he has been here for twenty years. Several years
+ago he took out papers and became an American citizen.”
+</p>
+
+<p>
+“And the young man?”
+</p>
+
+<p>
+Jane’s tone was vibrant with interest. It must be the man she had seen from her
+window whom they suspected most.
+</p>
+
+<p>
+“He professes to be American-born.”
+</p>
+
+<p>
+“Oh,” said the girl, rather disappointedly.
+</p>
+
+<p>
+“But,” continued Mr. Fleck, “there’s something queer about it all. He arrived
+in this country only three days before we went into the war. He had a
+certificate, properly endorsed, giving his birthplace as Cincinnati. He arrived
+on a Scandinavian ship. He speaks German as well and as fluently as he speaks
+English, both without accent.”
+</p>
+
+<p>
+“Perhaps he was educated abroad,” suggested Jane, rather amazed at finding
+herself seeking to defend him.
+</p>
+
+<p>
+“He must have been,” said Fleck, “yet I find it hard to believe that Germany at
+this time is letting any young German-American come home if he’s soldier
+material—and young Hoff’s appearance certainly suggests military training.”
+</p>
+
+<p>
+“It surely does.”
+</p>
+
+<p>
+“Unless,” continued Fleck, “there was some special object in sending him here.”
+</p>
+
+<p>
+“You think,” said Jane slowly, “they sent him here—to this country—as a spy.”
+</p>
+
+<p>
+“In our business we dare not think. We cannot merely conjecture. We must
+prove,” said Mr. Fleck. “Maybe the Hoffs are O.K. I do not know. Nobody knows
+yet. Let me tell you some of the circumstances. This much we do know. Von
+Bernstorff is gone. Von Papen is gone. Scores of active German sympathizers and
+propagandists have been rounded up and interned or imprisoned, yet, in spite of
+all we have done, their work goes on. A vast secret organization, well supplied
+with funds, is constantly at work in this country, trying to cripple our
+armies, trying to destroy our munition plants, trying to corrupt our citizens,
+trying to disrupt our Congress. Every move the United States makes is watched.
+As you probably know, every day now large numbers of American troops are
+embarking in transports in the Hudson.”
+</p>
+
+<p>
+“Yes,” said Jane, “you can see them from our windows.”
+</p>
+
+<p>
+“Now then,” said Mr. Fleck, lowering his voice impressively, “here is the fact.
+Some one somewhere on Riverside Drive is keeping close and constant tab on the
+warships and transports there in the river. We have managed recently to
+intercept and decipher some code messages. These messages told not only when
+the transports sailed but how many troops were on each and how strong their
+convoy was. Where these messages originate we have not yet learned. We are
+practically certain that some one in our own navy, some black-hearted traitor
+wearing an officer’s uniform—perhaps several of them—is in communication with
+some one on shore, betraying our government’s most vital secrets.”
+</p>
+
+<p>
+“I can’t believe it,” cried Jane, “our own American officers traitors!”
+</p>
+
+<p>
+“Undoubtedly some of them are,” said Mr. Fleck regretfully. “The German
+efficiency, for years looking forward to this war, carefully built up a
+far-reaching spy system. Years ago, long before the war was thought of—or at
+least before we in this country thought of it—many secret agents of
+Wilhelmstrasse were deliberately planted here. Many of them have been residents
+here for years, masking their real occupation by engaging in business,
+utilizing their time as they waited for the war to come by gathering for
+Germany all of our trade and commercial secrets. Some of these spies have even
+become naturalized, and they and their sons pass for good American citizens. In
+some cases they have even Americanized their names. Insidiously and
+persistently they have worked their way into places, sometimes into high places
+in our chemical plants, our steel factories, yes, even into high places in our
+army and navy and into governmental positions where they can gather information
+first-hand. In no other country has it been so easy for them, because of this
+one fact: so large a proportion of Uncle Sam’s population is of German birth or
+parentage. Why here in New York City alone there are more than three-quarters
+of a million persons, either German-born themselves or born of German parents.
+Many of them, the vast majority of them, probably, are loyal to America, but
+think how the plenitude of German names makes it easy for spies to get into our
+army and navy. Besides that, they employ evil men of other nationalities as
+spies, the criminal riffraff,—Danes, Swedes, Spaniards, Italians, Swiss and
+even South Americans,—all of whom are free to go and come as they choose in
+this country.”
+</p>
+
+<p>
+“I never realized before,” said Jane, “how many Germans there were all about
+us.”
+</p>
+
+<p>
+“In an effort to locate this particular band of naval spies,” continued Mr.
+Fleck, “we have combed the apartment houses and residences along the Drive.
+Three places in particular are under suspicion. The apartment of the Hoffs is
+one of these places. They moved in there thirty days after this country went to
+war. Ordinarily, where the occupants of an apartment are under suspicion, we
+take the superintendent of the building partly into our confidence and plant
+operatives in the house, or else we hire an apartment in the same building. In
+this case neither course is practicable. The superintendent of your building is
+a German-American and we dare not trust him, and there is no vacant apartment
+that we can rent. We have been watching the Hoffs from the outside as best we
+could. Carter, who has had charge of the shadowing, accidentally happened to
+overhear you give your address. He had procured a list of the tenants and
+remembered the location of your apartment. It struck him at once that you would
+be a valuable ally if you would consent to work with us.”
+</p>
+
+<p>
+“What is it that you wish me to do?” asked Jane wonderingly. “You’ll have to
+tell me how to go about it.”
+</p>
+
+<p>
+“All a good detective needs,” said Mr. Fleck, “is, let us say, three
+things—observation, addition and common sense. You must observe everything
+closely, be able to put two and two together and use your common sense. Do you
+know the Hoffs by sight?”
+</p>
+
+<p>
+“Only by sight.”
+</p>
+
+<p>
+“They live in the next apartment on your floor, do they not?”
+</p>
+
+<p>
+“Yes. Young Mr. Hoff’s bedroom is the room next to mine.”
+</p>
+
+<p>
+“Good,” cried Mr. Fleck. “Can you hear anything from the next apartment, any
+conversations?”
+</p>
+
+<p>
+“No, only muffled sounds.”
+</p>
+
+<p>
+“The windows overlook the river and the transports, do they not?”
+</p>
+
+<p>
+“Yes, the windows of Mr. Hoff’s bedroom and the room next. Their apartment is a
+duplicate of ours.”
+</p>
+
+<p>
+Mr. Fleck sprang up and crossed to the big safe. Opening an inner drawer he
+took out a small metal disk and handed it to her. Jane looked at it curiously.
+It bore no wording save the inscription “K-19.”
+</p>
+
+<p>
+“That,” said Mr. Fleck, “is the only thing I can give you in the way of
+credentials. Keep it somewhere safely concealed about your clothing and never
+exhibit it except in case of extreme necessity. If ever you are in peril any
+police officer will recognize it at once and will promptly give you all the
+assistance possible.”
+</p>
+
+<p>
+“But,” protested the girl, “I don’t know yet what I am to do.”
+</p>
+
+<p>
+“For the present I am trusting to your resourcefulness to make opportunities to
+help us. We are watching the house closely from the outside. Carter will
+identify you to the other operatives. Once a day I will expect you to call me
+up, not from your home but from a public ’phone. Here is my number. Say ‘this
+is Miss Jones speaking,’ and I will know who it is. I can communicate with you
+by note without arousing suspicion?”
+</p>
+
+<p>
+“Oh, yes, certainly.”
+</p>
+
+<p>
+“If at any time I have to call you on the ’phone, or if any of the other
+operatives want to communicate with you the password will be ‘I am speaking for
+Miss Jones.’”
+</p>
+
+<p>
+“Isn’t that exciting—a secret password,” cried Jane enthusiastically.
+</p>
+
+<p>
+“If you can manage it without compromising yourself too seriously, I wish you
+would make the young man’s acquaintance.”
+</p>
+
+<p>
+“That will be simple,” said Jane, remembering the admiring way in which he had
+raised his cup in her direction as she left the hotel.
+</p>
+
+<p>
+“If possible find out who their visitors are in the apartment and keep your
+eyes open for any sort of signalling to the transports. If ever there is an
+opportunity to get hold of notes or mail delivered to either of them, don’t
+hesitate to steam it open and copy it.”
+</p>
+
+<p>
+“Must I?” said Jane. “That hardly seems right or fair.”
+</p>
+
+<p>
+“Of course it’s right,” cried Mr. Fleck warmly. “Think of the lives of our
+soldiers that are at stake. The devilish ingenuity of these German spies must
+be thwarted at all costs. They seem to be able to discover every detail of our
+plans. Only two days ago one of our transports was thoroughly inspected from
+stem to stern. Two hours later twenty-six hundred soldiers were put aboard her
+on their way to France. Just by accident, as they were about to sail, a
+time-bomb was discovered in the coal bunkers, a bomb that would have sent them
+all to kingdom come.”
+</p>
+
+<p>
+“How terrible!”
+</p>
+
+<p>
+“Somebody aboard is a traitor. Somebody knew when that inspection was made.
+Somebody put that bomb in place afterward. That shows you the kind of enemies
+we are fighting.”
+</p>
+
+<p>
+Jane shuddered. She was thinking of the sailing of another transport, the one
+that had carried her brother to France.
+</p>
+
+<p>
+“Anything seems right after that,” she said simply.
+</p>
+
+<p>
+“Yes,” said Mr. Fleck, “there is only one effective way to fight those spying
+devils. We must stop at nothing. They stop at nothing—not even murder—to gain
+their ends.”
+</p>
+
+<p>
+“I know that,” said Jane hastily. “I saw something myself you ought to know
+about.”
+</p>
+
+<p>
+As briefly as she could she described the scene she had witnessed in the early
+morning hours from her bedroom window, the man following the younger Hoff,
+Hoff’s discovery and pursuit of him around the corner and of his return alone.
+</p>
+
+<p>
+“And in the morning,” she concluded, “they found a man’s body in the side
+street. He had a bullet through his heart. There was a revolver in his hand.
+The newspapers said that the police and the coroner were satisfied that it was
+a suicide. I caught a glimpse of Mr. Hoff’s face when he came back from around
+that corner. It was all convulsed with hate, the most terrible expression I
+ever saw. I’m almost certain he murdered that man. I’m sure it wasn’t a
+suicide.”
+</p>
+
+<p>
+“I’m sure, too, that it was no suicide,” said Mr. Fleck gravely. “The man who
+was found there was one of my men, K-19, the man whose badge I have just given
+you. He had been detailed to shadow the Hoffs.”

+<h2><a name="CHAPTER_IV"></a>CHAPTER IV<br/>
+THE CLUE IN THE BOOK</h2>
+
+<p>
+Subway passengers sitting opposite Jane Strong as she rode up-town from Mr.
+Fleck’s office, if they observed her at all—and most of them did—saw only a
+slim, good-looking young girl, dressed in a chic tailormade suit, crowned with
+a dashing Paris hat tilted at the proper angle to display best the sheen of her
+black, black hair, which after the prevailing fashion was pulled forward
+becomingly over her ears. Outwardly Jane was unchanged, but within her nerves
+were all atingle at the thought of the tremendous and fascinating
+responsibility so unexpectedly thrust upon her. Her mind, too, was aflame with
+patriotic ardor, but coupled with these new sensations was a persisting sense
+of dread, an intangible, unforgettable feeling of horror that kept cropping up
+every time her fingers touched the little metal disk in her purse.
+</p>
+
+<p>
+The man who had carried it yesterday, the other “K-19” who had undertaken to
+shadow those people next door, now lay dead with a bullet through his heart.
+Was there, she wondered, a similar peril confronting her? Would her life be in
+danger, too? Was that the reason Mr. Fleck had told her of her predecessor’s
+fate—to warn her how desperate were the men against whom she was to match her
+wits? Yet no sense of fear that projected itself into her busy brain as she
+cogitated over the task before her held her back. If anything she was rather
+thrilled at the prospect of meeting actual danger. What bothered her most was
+how she could best go about aiding Mr. Fleck and his men in their work.
+</p>
+
+<p>
+Her opportunity came far more quickly than she had anticipated. She had gotten
+off the train at the 96th Street station, purposing to walk the twenty odd
+blocks to her home as she pondered over the work that lay ahead of her. Busy
+with a horde of struggling new thoughts she proceeded along Broadway, for once
+in her life unheeding the rich gowns and feminine dainties so alluringly
+displayed in the shop windows. Suddenly she pulled herself together with a
+start. Directly ahead of her, plodding along in the same direction, was a
+figure that from behind seemed strangely familiar. She quickened her step until
+she caught up sufficiently with the man ahead to get a good glimpse of his side
+face. Nervously she caught her breath. Without any doubt it was the gray Van
+Dyke beard of old Otto Hoff.
+</p>
+
+<p>
+Where was he going? What was he doing? She paused and looked behind her,
+scanning the pavement on both sides of the street. She was half-hoping that she
+would discover Carter or some of his men shadowing their quarry, but her hope
+was vain. There was no one in the block at the moment but herself and Mr. Hoff.
+If Fleck’s men had been watching his movements, the old man certainly seemed to
+have eluded them.
+</p>
+
+<p>
+What should she do? Vividly there flashed into her mind her chief’s parting
+words.
+</p>
+
+<p>
+“Watch everything,” he had charged her. “Remember everything, report
+everything. No detail is too unimportant. If you see one of the Hoffs leave the
+house, don’t merely report to me that the old man or the young man left the
+house about three o’clock. That won’t do at all. I want to know the exact time.
+Was it six minutes after three or eleven minutes after three? I must know what
+direction he went, if he was alone, how long he was absent, where he went, what
+he did, to whom he talked. Here in my office I take your reports, Carter’s
+reports, a dozen other reports, and study them together. Things that in
+themselves seem trifling, unimportant, of no value, coupled with other
+seemingly unimportant trifles sometimes develop most important evidence.”
+</p>
+
+<p>
+To prove his point he had told her of the seemingly innocent wireless message
+that an operator, listening in, had picked up, at a time when Germans were
+still permitted to use the wireless station on Long Island for commercial
+messages to the Fatherland. On the face of it, it was the mere announcement of
+the death of a relative with a few details. But a little later the same
+operator caught the same message coming from another part of the country, with
+the details slightly different, and still later another message of the same
+purport. Evidently, by comparing the messages, the United States authorities
+had been able to work out a code.
+</p>
+
+<p>
+Remembering this, Jane decided that it was her particular duty just now to
+follow the old German and note everything he did. For several blocks she
+trailed along behind him, without arousing any suspicion on his part that he
+was being followed. He stopped once to light a cigarette, the girl behind him
+diverting suspicion by hastily turning to a shop window. Again he stopped, this
+time before the display of viands in the window of a delicatessen store.
+Thoughtfully Jane noted the number, observing, too, that the name of the
+proprietor above the door was obviously Teutonic. She was half-expecting to see
+her quarry turn in here, but he walked on to the middle of the next block,
+where he entered a stationery store.
+</p>
+
+<p>
+Hesitating but a second, to decide on a course of action, she followed him
+boldly into the store. She felt that she must ascertain just what he was doing
+in there. As she entered she saw that in the back part of the store was a
+lending library. Mr. Hoff had gone back to it and was inspecting the books
+displayed there. Unhesitatingly she, too, approached the book counter.
+</p>
+
+<p>
+“Have you ‘Limehouse Nights’?” she asked the attendant, naming the first book
+that came into her head. She had a copy of the book at home, but that seemed to
+be the only title she could think of.
+</p>
+
+<p>
+“We have several copies,” the girl in charge answered, “but I think they are
+all out. I’ll look.”
+</p>
+
+<p>
+As the clerk examined the shelves, Jane kept up a desultory talk with her,
+questioning her about various books on the shelves, all the while watching the
+old German out of the corner of her eye. His back was toward her, and he seemed
+to be examining various books on the shelves, turning over the pages as if
+unable to decide what he wanted. Curious as to what his taste in reading was,
+Jane endeavored to locate each book that he removed from its place, her idea
+being that she would later try to discover their titles. To her amazement she
+found that it was invariably the third book in each shelf that he removed and
+examined—the third from the end. It did not appear to her that he was examining
+the contents of the pages so much as searching them as if he expected to find
+something there.
+</p>
+
+<p>
+All at once, as she furtively watched from behind him, she heard him give a
+little pleased grunt and she saw him picking out from between the leaves of the
+book a fragment of paper, which he held concealed in his hand. Watching
+closely, Jane saw him thrust this same hand into his trousers pocket, and when
+he brought it out she was certain that the hand was empty. What did this
+curious performance mean? What was the little slip of paper he had found in the
+book? Why had he concealed it in his pocket?
+</p>
+
+<p>
+Still keeping her attention riveted on him, she picked up a book to mask her
+occupation and pretended to be turning its pages. She was glad she had done so,
+for a minute later old Hoff wheeled suddenly and looked sharply about him.
+Apparently having his suspicions disarmed by seeing only herself and the clerk
+there, he turned again to the bookshelves. Jane this time saw him thrust his
+fingers into his waistcoat pocket and withdraw therefrom,—she was almost
+certain of it,—a little slip of paper. She saw him remove from the second row
+of books the fifth from the end, open it quickly and close it again and then
+restore it to its place. As he did so he turned to leave the store.
+</p>
+
+<p>
+“Didn’t you find anything to read to-day, Mr. Hoff?” the clerk asked.
+</p>
+
+<p>
+“Nodding,” he answered. “You keep novels, trash, nodding worth while.”
+</p>
+
+<p>
+Her nerves aquiver, Jane waited until he was out of the store and then stepped
+briskly to the place where he had stood. Hastily she pulled forth the fifth
+book from the end in the second row. Turning its pages she came upon what she
+had anticipated,—a strip of yellow manila paper,—the paper she was sure she had
+seen him take from his pocket. Hastily she examined it, expecting to find some
+message written there. To her chagrin it was just a meaningless jumble of
+figures in three columns.
+</p>
+

+
+<p>
+Her first thought was to thrust the little scrap of paper in her purse and
+start again in pursuit of old Hoff, but a sudden light began to dawn on her.
+This was a cipher message, of course. The old man had left it here for some one
+to come and get. If she followed Hoff, how was she to discover who the message
+was for? Puzzled as to what she should do, she borrowed a pencil from the clerk
+on the pretense of writing a postal and hastily copied the figures, after which
+she restored the slip to the book in which she had found it.
+</p>
+
+<p>
+Glancing about undecidedly, wondering if it would do to take the clerk into her
+confidence, wishing she had some means of reaching Mr. Fleck and asking his
+advice, she spied in a drug-store just across the street a telephone booth. She
+could telephone from there and at the same time keep her eye on the store.
+Quickly she did so, twisting her head around all the time she was ’phoning to
+make sure that no one entered opposite.
+</p>
+
+<p>
+“Is this Mr. Fleck?” she asked. “This is Miss Jones.”
+</p>
+
+<p>
+“So soon?” came back his voice. “What has happened? What is the matter? Have
+you changed your mind?”
+</p>
+
+<p>
+“Not at all,” she answered indignantly. “I’ve discovered something already—a
+cipher message.”
+</p>
+
+<p>
+“What’s that?”
+</p>
+
+<p>
+Even over the wire she could sense the eagerness in Mr. Fleck’s tone, and a
+sense of achievement brought a radiant glow to her cheek.
+</p>
+
+<p>
+“I ran into that man—you know whom—”
+</p>
+
+<p>
+“The young one?” he interrupted.
+</p>
+
+<p>
+“No, the uncle.”
+</p>
+
+<p>
+“Yes, yes, go on,” cried Mr. Fleck impatiently.
+</p>
+
+<p>
+“I followed him along Broadway after I got off at 96th Street and into a
+library and stationery store. I watched him fuss over the books there, and I
+think he got a slip of paper with a message out of one of them.”
+</p>
+
+<p>
+“Good,” cried Mr. Fleck, “that is something new. Go on.”
+</p>
+
+<p>
+“And then he slipped a paper into a book—”
+</p>
+
+<p>
+“Did you notice what book?”
+</p>
+
+<p>
+“I don’t know the title. It was the fifth book from the end on the second
+shelf, and I got the paper and copied it.”
+</p>
+
+<p>
+“Splendid. What did the message say?”
+</p>
+
+<p>
+“It’s just a lot of figures. I put it back after copying it, and I am in a
+drug-store across the street where I can watch to see if any one comes to get
+the message. What shall I do now?”
+</p>
+
+<p>
+“Can you remain there fifteen minutes without arousing suspicion?”
+</p>
+
+<p>
+“Certainly. I’ll say I am waiting for some one.”
+</p>
+
+<p>
+“Good. I’ll get in touch with Carter at once. He’ll tell you what to do when he
+arrives.”
+</p>
+
+<p>
+Impatiently Jane sat there, keeping vigilant watch on the entrance across the
+street, determined to be able to describe minutely each person that entered.
+From time to time she surreptitiously studied the postcard on which she had
+jotted down the mysterious numbers. How utterly meaningless they looked. Surely
+it would be impossible for any one, even Mr. Fleck, to decipher any message
+that these figures might convey. It would be impossible unless one had the key.
+Figures could be made to mean anything at all. She doubted if her discovery
+could be of much importance after all, yet certainly Mr. Fleck had seemed quite
+excited about it.
+</p>
+
+<p>
+She spied Carter passing in a taxi. Two other men were with him. Her first
+impulse was to run out in the street and signal to him, but she waited,
+wondering what she should do. She was glad she had not acted impulsively, for a
+moment later Carter entered alone, evidently having left the car somewhere
+around the corner. She expected that he would address her at once, but that was
+not Carter’s way. He went to the soda counter and ordered something to drink,
+his eyes all the while studying his surroundings. Presently he pretended to
+discover her sitting there. To all appearances it might have been an entirely
+casual meeting of acquaintances.
+</p>
+
+<p>
+“Good-morning, Miss Jones,” he said quite cordially, extending his hand. “I’m
+lucky to have met you, for my daughter gave me a message for you.”
+</p>
+
+<p>
+He put just a little stress on the words “my daughter” and Jane understood that
+he was referring to “Mr. Fleck.”
+</p>
+
+<p>
+“Indeed,” she replied, “what is it?”
+</p>
+
+<p>
+“She wants you to go down-town at once and meet her at Room 708—you know the
+building.”
+</p>
+
+<p>
+“Aren’t you coming, too?”
+</p>
+
+<p>
+“Not right away. I have some errands to do in the neighborhood. I’ve got to buy
+a book for a birthday present. There’s a library around here somewhere, isn’t
+there?”
+</p>
+
+<p>
+“Just across the street,” said Jane, entering into the spirit of the masked
+conversation with interest. “I was looking at a fine book over there a few
+minutes ago. You’ll find it on the second shelf—the fifth book from the end, on
+the north side of the store.”
+</p>
+
+<p>
+“I’ll remember that,” said Carter, repeating, “the fifth book on the second
+shelf.”
+</p>
+
+<p>
+“That’s right,” said Jane, as they left the drug-store together.
+</p>
+
+<p>
+“Which way did the old man go?” asked Carter.
+</p>
+
+<p>
+“Down Broadway—toward home,” she replied. “I wanted to follow him, but it
+seemed more important to stay here and watch to see if any one came for the
+message he left there in the book.”
+</p>
+
+<p>
+“You did just right, and the Chief is tickled to death. He wants to see you
+right away. You have a copy of the message, haven’t you?”
+</p>
+
+<p>
+“Yes, do you wish to see it?”
+</p>
+
+<p>
+“No, but he does. Has anybody entered the store since you were there?”
+</p>
+
+<p>
+“Nobody, that is no one but a couple of girls.”
+</p>
+
+<p>
+“What did they look like? Describe them.”
+</p>
+
+<p>
+“Why,” Jane faltered, “I did not really notice. I was not looking for girls. I
+was watching to see that no other men entered the store.”
+</p>
+
+<p>
+Carter shook his head.
+</p>
+
+<p>
+“You ought to have spotted them, too. You never can tell who the Germans will
+employ. They have women spies, too,—clever ones.”
+</p>
+
+<p>
+“I never thought of their using girls,” protested Jane.
+</p>
+
+<p>
+“Humph,” snapped Carter, “ain’t we using you? Ain’t one of our best little
+operatives right this minute working in a nursegirl’s garb pulling a baby
+carriage with a baby in it up and down Riverside Drive? Well, it can’t be
+helped. You’d better beat it down-town to the Chief right away.”
+</p>
+
+<p>
+“I’ll take a subway express,” said Jane, feeling somewhat crestfallen at his
+implied suggestion of failure.
+</p>
+
+<p>
+Twenty-five minutes later found her once more in Mr. Fleck’s office. Thrilling
+with the excitement of it all she told him in detail how she had followed old
+Hoff and of his peculiar actions in the bookstore.
+</p>
+
+<p>
+“And here,” she said, presenting the postcard, “is an exact copy of the cipher
+message he left there. I copied every figure, in the columns, just as they were
+set down. I don’t suppose though you’ll be able to make head or tail out of it.
+I know I can’t.”
+</p>
+
+<p>
+“Don’t be too sure of that,” smiled Chief Fleck, as he took the card. “When you
+get used to codes, most of them identify themselves at the first glance—at
+least they tell what kind of a code it is. That’s one thing about the Germans
+that makes their spy work clumsy at times. They are so methodical that they
+commit everything to writing. Now the most important things I know are right in
+here”—he tapped his head. “Every once in a while they ransack my rooms, but
+they never find anything worth while. Now this code”—he was studying the card
+intently—“seems to be one of a sort that our friends from Wilhelmstrasse are
+ridiculously fond of using. It is manifestly a book code.”
+</p>
+
+<p>
+“A book code,” Jane repeated perplexedly. “I don’t understand.”
+</p>
+
+<p>
+“It is very simple when two persons who wish to communicate with each other
+secretly both have a copy of some book they have agreed to use. They write
+their message out and then go through the book locating the words of the
+message by page, line and word. That’s what the three columns mean. Our only
+problem is to discover which is the book they both have. They often employ the
+Bible or a dictionary or—”
+</p>
+
+<p>
+He stopped abruptly and studied the columns of figures.
+</p>
+
+<p>
+“This code,” he went on, “on its face is from a book that has at least 544
+pages. One of the pages has at least 76 lines—that’s the middle column—so the
+book must be set in small type.”
+</p>
+
+<p>
+“What book do you suppose it is?” asked Jane interestedly. She was glad now
+that she had listened to Carter. She was sure she was going to like being in
+the service. It was all so interesting, and she was learning so many
+fascinating things.
+</p>
+
+<p>
+“If my theory is right those letters indicate that the book used was an
+almanac. That’s the book that Wilhelmstrasse made use of when a wireless
+message was sent in cipher to the German ambassador directing him to warn
+Americans not to sail on the Lusitania. They betrayed themselves at the Embassy
+by sending out to buy a copy of this almanac. Let’s see how our theory works
+out.”
+</p>
+
+<p>
+Taking up an almanac that lay on his desk he began turning to the pages
+indicated in the first column of figures, checking off the lines indicated in
+the second column and putting a ring around the words marked by the third
+column of figures.
+</p>
+
+<p>
+“Let’s see—page 534—fifth line—second word—that’s (eight). Now then—page
+331—that’s the chronology of the war in the almanac, so I guess we are on the
+right track—fifty-fourth line—sixth word—(transport).”
+</p>
+
+<p>
+“Isn’t it wonderful!” cried Jane.
+</p>
+
+<p>
+“Damn them,” he exploded. “I know we are on the right track. Some transports
+with our troops sailed this morning, and already the German spies are spreading
+the news, hoping to get it to one of their unspeakable U-boats.”
+</p>
+
+<p>
+Quickly he ran through the rest of the cipher, writing it out as he went along:
+</p>
+
+<p>
+EIGHT—TRANSPORT—SAILED—THURSDAY—15,000—INFANTRY—FIVE DESTROYERS.
+</p>
+
+<p>
+As Fleck finished the message his face became almost black with rage.
+</p>
+
+<p>
+“Damn them,” he cried again, “in spite of everything we do they get track of
+all our troop movements. Their information, whenever we succeed in intercepting
+it, is always accurate. If I had my way I’d lock up every German in the country
+until the war was over, and I’d shoot a lot of those I locked up. Until the
+whole country realizes that we are living in a nest of spies—that there are
+German spies all around us, in every city, in every factory, in every regiment,
+on every ship, everywhere right next door to us—this country never can win the
+war.”
+</p>
+
+<p>
+“What does the ‘97’ at the end mean?” questioned Jane timidly, a little bit
+frightened at his outburst, yet more than ever realizing the vast importance of
+his work—and hers.
+</p>
+
+<p>
+“Oh, that’s nothing. Probably old Hoff’s number. Most spies are known just by
+numbers.”
+</p>
+
+<p>
+“Yes, of course,” said Jane, flushing as she recalled that she herself was now
+“K-19.” Was she a spy? Was Mr. Fleck a chief of spies? She always had looked on
+a spy as a despicable sort of person, yet surely the work in which they both
+were engaged was vital to American success at arms—a patriotic and important
+service for one’s country.
+</p>
+
+<p>
+“I suppose,” she said thoughtfully, unwilling to pursue the chain of her own
+thought any further, “that there is evidence enough now to arrest old Mr. Hoff
+right away.”
+</p>
+
+<p>
+“You bet there is,” said Mr. Fleck emphatically, “but that is the last thing I
+am thinking of doing yet. He is only one link in a great chain that extends
+from our battleships and transports there in the North River clear into the
+heart of Berlin. We’ve got to locate both ends of the chain before we start
+smashing the links. We’ve got to find who it is in this country that is
+supplying the money for all their nefarious work, from whom they get their
+orders, how they smuggle their news out. Most of all we have got to find where
+the end of the chain is fastened in our own navy. The traitors there are the
+black-hearted rascals I would most like to get. They are the ones we’ve got to
+get.”
+</p>
+
+<p>
+“Yes, indeed,” assented Jane, suddenly recalling the navy lieutenant she had
+seen in the Ritz chatting so confidentially with old Otto Hoff’s nephew. Was
+he, she wondered, one of the links in the terrible chain? Was he the end—the
+American end of the chain?
+</p>
+
+<p>
+“We’re certain about the old man now,” said Fleck, rising as if to indicate
+that the interview was at an end. “We’ve got to get the young fellow next.
+There is nothing in this to implicate him. That’s your job. Find out all you
+can about him. Get acquainted with him, if possible. That’s one of the weakest
+spots about all German spies. They can’t help boasting to women. Try to get to
+know this Fred Hoff. It’s most important.”
+</p>
+
+<p>
+“I’ll do more than try,” said Jane spiritedly. “I’ll get acquainted right away.
+I’ll make him talk to me.”

+<h2><a name="CHAPTER_V"></a>CHAPTER V<br/>
+ON THE TRAIL</h2>
+
+<p>
+Few men, even fathers, realize how utterly inexperienced is the average
+well-brought-up girl, just emerged from her teens, in the affairs of the great
+mysterious world that lies about her. A boy, in his youth living over again the
+history of his progenitors, escapes his nurse to become an adventurer. At ten
+he is a pirate, at twelve a train robber, at fourteen an aviator, actually
+living in all his thoughts and experiences the life of his hero of the moment,
+learning all the while that the world about him is full of adventurers like
+himself, ready to dispute his claims at the slightest pretext, or to carry off
+his booty by prevailing physical force.
+</p>
+
+<p>
+Well-brought-up girls seldom are fortunate enough to have such educative
+experiences. Their friends are selected for them, gentle untaught creatures
+like themselves. Few of them learn much of the practical side of life. A boy is
+delighted at knowing the toughest boy in the neighborhood. A girl’s ambitions
+always are to know girls “nicer” than she is. The average girl emerges into
+womanhood with her eyes blinded, uninformed on the affairs of life, business,
+politics, untrained in anything useful or practical, knowing more of romance
+and history than she does of present-day facts.
+</p>
+
+<p>
+If Chief Fleck had understood how really inexperienced Jane Strong actually
+was, it is a question whether he would have ventured to entrust so important a
+mission to her as he had done. Jane herself, as she left his office, aroused by
+his revelations of the treacherous work of Germany’s spies, and uplifted by his
+appeal to her patriotism, felt enthusiastically capable of obeying his
+instructions. It seemed very simple, as he had talked about it. All she had to
+do was to get acquainted with the young man next door. Yet the further the
+subway carried her from Mr. Fleck’s office after her second visit there that
+morning, the more her heart sank within her, and the fuller her mind became of
+misgivings.
+</p>
+
+<p>
+In a big city next door in an apartment house is almost the same thing as miles
+away. She ransacked her brain, trying to remember some acquaintance who might
+be likely to know the Hoffs, but failed utterly to recall any one. She reviewed
+all possible means of getting acquainted but could find none that seemed
+practical. Never in her life had she spoken to a man without having been
+introduced to him—except of course to Carter and Mr. Fleck, and these men, she
+told herself, were government officials, something like policemen, only nicer.
+At any rate, she knew them only in a business way, not socially. If she was to
+be successful in learning much about the Hoffs—about young Mr. Hoff—she felt
+that it was necessary to make them social acquaintances.
+</p>
+
+<p>
+She must manage to meet Frederic Hoff in some proper way, but how? She thought
+of such flimsy tricks as dropping a handkerchief or a purse in the elevator
+some time when he happened to be in it, but rejected the plan as
+disadvantageous. “Nice” girls did not do that sort of thing, and even though
+she was seeking to entrap her neighbor she did not for a moment wish him to
+consider her as belonging to the other sort. It rather annoyed her to find that
+she cared what kind of an impression she made on him. What difference did it
+make what a German spy thought of her, especially a murderer? Yet, she argued
+with herself, the better the impression she made at first the more likely she
+would be to gain his confidence, and that she knew would delight Mr. Fleck. Was
+Frederic Hoff, too, really, she wondered, a spy? Her face colored as she
+recalled the mental picture she last had had of him, gallantly and admiringly
+raising his cup to her as she left the Ritz, not obtrusively or impudently, but
+so subtly that she was sure that no one had observed it but herself. It seemed
+preposterous to associate the thought of murder with a man like him.
+</p>
+
+<p>
+As she entered the apartment house she was arguing still with herself about
+him. Her intuition told her that Frederic Hoff was a gentleman, and how could a
+gentleman be what Mr. Fleck seemed to think he was? As the door swung to behind
+her she gave a little quick breath of delight, for she had caught sight of a
+uniformed figure standing by the switchboard. She had recognized him at once.
+It was the naval lieutenant who had been at the Ritz. She heard him saying to
+the girl at the switchboard:
+</p>
+
+<p>
+“Tell Mr. Hoff, young Mr. Hoff, that Lieutenant Kramer is here. I’ll wait for
+him down-stairs.”
+</p>
+
+<p>
+Quick as a flash a course of action came into her mind. She saw an opportunity
+too good to be neglected. She hurried forward to where the lieutenant was
+standing, her hand outstretched, with a smile of recognition—feigned, but
+well-feigned—on her lips.
+</p>
+
+<p>
+“Why, Lieutenant Kramer,” she cried, “how delightful. Have you really kept your
+promise at last and come to see the Strongs?”
+</p>
+
+<p>
+She could hardly restrain her amusement as she watched the embarrassed young
+officer strive in vain to recall where it was that he had met her. She had
+relied on the fact that the men in the navy meet so many girls at social
+functions that it is impossible for any of them to remember all they had met.
+</p>
+
+<p>
+“Really, Miss—” he stammered, struggling for some fitting explanation.
+</p>
+
+<p>
+“Don’t tell me,” she warned reprovingly, “that it isn’t Jane Strong that you
+are here to see, after all those nice things you said to me that day we had tea
+aboard your ship.”
+</p>
+
+<p>
+She was hoping he would not insist on going into particulars as to which ship
+it was. Fortunately she had been to functions on several of the war vessels, so
+that she might find a loop-hole if he was too insistent on details.
+</p>
+
+<p>
+“Indeed, Miss Strong,” said Kramer, gallantly pretending to recall her, “I’m
+delighted to see you again. I’ve been intending to come to see you for ever so
+long, but you understand how busy we are now. In fact, it was business that
+brought me here to-day. I’m calling on Mr. Hoff, who lives here, to take him to
+lunch to discuss some important matters.”
+</p>
+
+<p>
+At his last phrase Jane’s heart thrilled. What important matters could there be
+that a navy lieutenant could fittingly discuss with a German, with the nephew
+of the man whose secret code message they had just succeeded in reading?
+Determining within herself to keep fast hold on the beginning she had made, she
+masked her real thoughts and let her face express frank disappointment.
+</p>
+
+<p>
+“How horrid of you,” she continued, “when I was just going to insist that you
+stay and have luncheon with us.”
+</p>
+
+<p>
+He was protesting that it was quite out of the question when the elevator
+brought down her mother, whom Jane at once summoned as an ally, feeling sure
+that considering how many men of her daughter’s acquaintance she had met, it
+would be perfectly safe to keep up the deception.
+</p>
+
+<p>
+“Oh, mother,” she cried, “you remember Lieutenant Kramer, don’t you? I’ve just
+been urging him to stay and have luncheon with us. Do help me persuade him.”
+</p>
+
+<p>
+“Of course I remember Mr. Kramer,” fibbed the matron cordially, all unaware of
+her daughter’s duplicity. “Do stay, Mr. Kramer, and have luncheon with Jane. I
+ordered luncheon for four, expecting to be home, and now I’ve been called away,
+but your aunt is there to chaperone you. It spoils the servants so to prepare
+meals and have no one to eat them, to say nothing of displeasing Mr. Hoover.
+It’s really your duty—your duty as a patriot—to stay and prevent a food-waste.”
+</p>
+
+<p>
+“I’ve just been trying to explain to your daughter that I was taking Mr. Hoff
+to luncheon with me. Here he is now.”
+</p>
+
+<p>
+Mrs. Strong’s eyes swept the tall figure approaching appraisingly and
+apparently was pleased with his aspect. As Mr. Hoff was presented she hastened
+to include him in the invitation to luncheon.
+</p>
+
+<p>
+“Have pity on a poor girl doomed to eat a lonely luncheon by her parent’s
+neglect,” urged Jane. “Really, you must come, both of you. Nice men to talk to
+are so scarce in these war times that I have no intention of letting you
+escape.”
+</p>
+
+<p>
+“I’m in Kramer’s hands,” said Frederic Hoff gallantly, “but if he takes me to
+some wretched hotel instead of accepting such a charming invitation as this, my
+opinion of him as a host will be shattered.”
+</p>
+
+<p>
+“But,” struggled Kramer, realizing that it must be a case of mistaken identity
+and sure now that he never had met either Jane or her mother before, “we have
+some business to talk over.”
+</p>
+
+<p>
+“Business always can wait a fair lady’s pleasure,” said Hoff. “Is this ruthless
+war making you navy men ungallant?”
+</p>
+
+<p>
+With a mock gesture of surrender, and as a matter of fact, not at all averse to
+pursuing the adventure further, Lieutenant Kramer permitted Jane to lead the
+way to the Strong apartment.
+</p>
+
+<p>
+Soon, with the familiarity of youth and high spirits, the three of them were
+merrily chatting on the weather, the war, the theater and all manner of things.
+Jane, in the midst of the conversation, could not help noting that Hoff had
+seated himself in a chair by the window where he seemed to be keeping a
+vigilant eye on the ships that could be seen from there. Even at the luncheon
+table he got up once and walked to the window to look out, making some clumsy
+excuse about the beautiful view.
+</p>
+
+<p>
+Determined to press the opportunity, Jane endeavored to turn the conversation
+into personal channels.
+</p>
+
+<p>
+“You are an American,” she said turning to Hoff, “are you not? I’m surprised
+that you are not in uniform, too.”
+</p>
+
+<p>
+“A man does not necessarily need to be in uniform to be serving his
+government,” he replied. “Perhaps I am doing something more important.”
+</p>
+
+<p>
+“But you are an American, aren’t you?” she persisted almost impudently, driven
+on by her eagerness to learn all she possibly could about him.
+</p>
+
+<p>
+“I was born in Cincinnati,” he replied hesitantly.
+</p>
+
+<p>
+She could not help observing how diplomatically he had parried both her
+questions. Mentally she recorded his exact words with the idea in her mind of
+repeating what he had said verbatim to her chief.
+</p>
+
+<p>
+“Then you <i>are</i> doing work for the government?”
+</p>
+
+<p>
+Intensely she waited for his answer. Surely he could find no way of evading
+such a direct inquiry as this.
+</p>
+
+<p>
+“Every man who believes in his own country,” he answered, modestly enough, yet
+with a curious reservation that puzzled her, “in times like these is doing his
+bit.”
+</p>
+
+<p>
+She felt far from satisfied. If he was born in America, if he really was an
+American at heart, his replies would have been reassuring, but his name was
+Hoff. His uncle was a German-American, a proved spy or at least a messenger for
+spies. If her guest still considered Prussia his fatherland the answers he had
+made would fit equally well.
+</p>
+
+<p>
+“You’re just as provokingly secretive as these navy men,” she taunted him.
+“When I try to find out now where any of my friends in the navy are stationed
+they won’t tell me a thing, will they, Mr. Kramer?”
+</p>
+
+<p>
+“I’ll tell you where they all are,” said Lieutenant Kramer. “Every letter I’ve
+had from abroad recently from chaps in the service has had the same address—‘A
+deleted port.’”
+</p>
+
+<p>
+“I really think the government is far too strict about it,” she continued. “My
+only brother is over there now fighting. All we know is that he is ‘Somewhere
+in France.’ War makes it hard on all of us.”
+</p>
+
+<p>
+“Yet after all,” said Hoff soberly, “what are our hardships here compared to
+what people are suffering over there, in France, in Belgium, in Germany, even
+in the neutral countries. They know over there, they have known for three
+years, greater horrors than we can imagine.”
+</p>
+
+<p>
+The longer she chatted with him, the more puzzled Jane became. He seemed to
+speak with sincerity and feeling. Her intuition told her that he was a man of
+honor and high ideals, and yet in everything he said there was always reserve,
+hesitation, caution, as if he weighed every word before uttering it. Intently
+she listened, hoping to catch some intonation, some awkward arrangement of
+words that might betray his tongue for German, but the English he spoke was
+perfect—not the English of the United States nor yet of England, but rather the
+manner of speech that one hears from the world-traveler. Question after
+question she put, hoping to trap him into some admission, but skilfully he
+eluded her efforts. She decided at last to try more direct tactics.
+</p>
+
+<p>
+“Your name has a German sound. It is German, isn’t it?” she asked.
+</p>
+
+<p>
+“I told you I was born in Cincinnati,” he answered laughingly. “Some people
+insist that that is a German province.”
+</p>
+
+<p>
+“But you have been in Germany, haven’t you?”
+</p>
+
+<p>
+“Why do you ask?”
+</p>
+
+<p>
+“I was wondering if you had not lived in that country?”
+</p>
+
+<p>
+“I could not well have been there without having lived there, could I?”
+</p>
+
+<p>
+Kramer came to her rescue.
+</p>
+
+<p>
+“Of course he has lived there. Mr. Hoff and I both attended German
+universities. That was what brought us together at the start—our common bond.”
+</p>
+
+<p>
+“Did you attend the same university?” asked Jane. She felt that at last she was
+on the point of finding out something worth while.
+</p>
+
+<p>
+“No,” said Kramer, “unfortunately it was not the same university.”
+</p>
+
+<p>
+She caught her breath and blushed guiltily. If Mr. Kramer had attended a German
+university he could not be an Annapolis graduate. He must be a recent comer in
+the American navy. She knew that since the war began some civilians had been
+admitted. It had just dawned on her that if this was the case, since visiting
+on board ships was no longer permitted, it clearly was impossible for her to
+have met him at any function on a warship. He must have known all along that
+she knew she never had met him. He must have been aware, too, that her mother
+did not know him. She felt that she was getting into perilous waters and
+fearful of making more blunders refrained from further questions. A vague alarm
+began to agitate her. If he had detected her ruse when she first had spoken to
+him, why had he not admitted it? What had been his purpose in accepting her
+invitation and in bringing into it his German friend, Mr. Hoff?
+</p>
+
+<p>
+The ringing of the telephone bell came as a welcome interruption. A maid
+summoned her to answer a call, and excusing herself from the table she went to
+the ’phone desk in the foyer.
+</p>
+
+<p>
+“Hello, is this you, Miss Strong?”
+</p>
+
+<p>
+It was Carter’s voice, but from the anxious stress in it she judged that he was
+in a state of great perturbation.
+</p>
+
+<p>
+“Yes, it is Jane Strong speaking,” she answered.
+</p>
+
+<p>
+“You know who this is?”
+</p>
+
+<p>
+“Of course. I recognize your voice. It’s Mr. C—”
+</p>
+
+<p>
+A warning “sst” over the ’phone checked her before she pronounced the name and
+starting guiltily she turned to look over her shoulder, feeling relieved to see
+the two men still chatting at the table, apparently paying no attention to her.
+</p>
+
+<p>
+“I understand,” she answered quickly. “What is it?”
+</p>
+
+<p>
+“You know that book I told you I was going to buy?”
+</p>
+
+<p>
+“Yes, yes!”
+</p>
+
+<p>
+“It’s not there.”
+</p>
+
+<p>
+“What’s that? The book is gone!”
+</p>
+
+<p>
+“The book is there all right, but it’s not the book I want.”
+</p>
+
+<p>
+“Are you sure,” she questioned, “that you looked at the right book?”
+</p>
+
+<p>
+“I looked at the one you told me to.”
+</p>
+
+<p>
+“Are you certain—the fifth book on the second shelf.”
+</p>

+<p class="caption">Had he been standing there listening? How much had he heard?</p>
+</div>
+
+<p>
+She heard a movement behind her and turning quickly saw Frederic Hoff standing
+behind her, his hat and stick in hand. Panic-stricken, she hung up the receiver
+abruptly. Had he been standing there listening? How much had he heard? He would
+know, of course, what “the fifth book on the second shelf” signified. Had her
+carelessness betrayed to him the fact that he and his uncle were being closely
+watched? Anxiously she studied his face for some intimation of his thoughts. He
+was standing there smiling at her, and to her agitated brain it seemed that in
+his smile there was something sardonic, defying, challenging.
+</p>
+
+<p>
+“I cannot tell you, Miss Strong, how much I have enjoyed your hospitality. You
+made the time so interesting that I had no idea it was so late. You will excuse
+me if I tear myself away at once. I have some important business that demands
+my immediate attention.”
+</p>
+
+<p>
+“I hope you’ll come again,” she managed to stammer, “and you, too, Mr. Kramer.”
+</p>
+
+<p>
+White-faced and terrified she escorted them out, leaving the telephone bell
+jangling angrily. As the door closed behind them, she sank weak and faint into
+a chair, not daring yet to go again to the ’phone until she was sure they were
+out of hearing.
+</p>
+
+<p>
+What was the “immediate business” that was calling them away so suddenly? She
+was more than afraid that her incautious use of the phrase “the fifth book on
+the second shelf” had betrayed her. What else could it mean? Why else would
+they have departed so abruptly?
+</p>
+
+<p>
+Mustering up her strength and courage she went once more to the ’phone.
+</p>
+
+<p>
+“Hello, hello, is that you, Miss Strong? Some one cut us off,” Carter’s voice
+was impatiently saying.
+</p>
+
+<p>
+“Hello, Mr. Carter,” she called, “this is Jane Strong speaking. Where can I see
+you at once? It’s most important.”
+</p>
+
+<p>
+“I’ll be sitting on a bench along the Drive two blocks north of your house
+inside of ten minutes.”
+</p>
+
+<p>
+“I’ll meet you there,” she answered quickly, with a feeling of relief.
+</p>
+
+<p>
+The situation was becoming far too complicated, she felt, for her to handle
+alone. Carter would know what to do. If Hoff and Kramer had learned from her
+about the trailing of old Hoff, the sooner it was reported to more experienced
+operatives than she was the better.
+</p>
+
+<p>
+“Don’t speak to me when you see me sitting on the bench,” warned Carter. “Just
+sit down there beside me and wait till I make sure no one is watching us. I’ll
+speak to you when it’s safe.”
+</p>
+
+<p>
+“I understand,” she answered. “Good-by.”
+</p>
+
+<p>
+As she hastened to don her hat and coat she was almost overwhelmed by a
+revulsion of feeling. Two days ago the world about her had seemed a carefree,
+pleasant, even if sometimes boresome place. Now she shudderingly saw it
+stripped of its mask and revealed for the first time in all its hideousness, a
+place of murders and spying and secret machinations. People about her were no
+longer more or less interesting puppets in a play-world. They were vivid
+actualities, scheming and planning to thwart and overcome each other. Almost
+she wished that her dream had been undisturbed and that she had not been waked
+up to the realities. Almost she was tempted to abandon her new-found
+occupation.
+</p>
+
+<p>
+Then, once more, a feeling of patriotic fervor swept over her. She thought of
+her brother fighting somewhere in the trenches. She pictured to herself the
+other brave soldiers in the great ships in the Hudson. She remembered the evil
+plotters with their death-dealing bombs, striving to bring about a ghastly end
+for them all before they might strengthen the lines of the Allies. She thought,
+too, of those humanity-defying U-boats, forever at their devilish work, guided
+to their prey by crafty, spying creatures right here in New York, more than
+likely by the very people next door.
+</p>
+
+<p>
+With her pretty lips set in a resolute line she left the house and walked
+rapidly north. Come what may she would go on with it. Her country needed her,
+and that was all-sufficient.

+THE MISSING MESSAGE</h2>
+
+<p>
+After Jane left Carter at the drug-store, he did not cross immediately to the
+bookshop opposite. His detective work was not of that sort. He strolled
+leisurely around the corner long enough to give some directions to his two
+aides waiting there and then, moving across the street, paused in front of the
+window of books as if something there had attracted his attention. All the
+while he was keeping a sharp eye for any person who looked as if they might be
+connected in any way with old Hoff. Satisfied that his entrance was unobserved
+he strolled casually in and began looking over the volumes in the lending
+library. The lone clerk in the store—a young woman—at first volunteered some
+suggestions, but as they went unheeded she returned to her work of posting up
+the accounts.
+</p>
+
+<p>
+As soon as her attention was occupied Carter moved at once to the end of the
+shelf that Miss Strong had indicated and removed the fifth book. To his
+amazement he found nothing whatever concealed between the leaves. The books on
+either side on the same shelf failed to yield up anything. He tried the shelf
+above and the shelf below. Perhaps Miss Strong had been mistaken in the
+directions. He examined the books at the other end. There was nothing there. He
+recalled that the girl had said that no one except two girls had entered the
+store between the time she had discovered and copied the cipher and the time of
+his arrival. If these girls had not taken the message away there could be only
+one other explanation—the clerk in the bookstore must have removed it and
+concealed it somewhere.
+</p>
+
+<p>
+“Which of the war books do you think the best?” he asked for the purpose of
+starting a conversation.
+</p>
+
+<p>
+“There’s that many it is hard to say, sir,” the young woman answered.
+</p>
+
+<p>
+Something in her inflection made him look sharply at her. Her accent surely was
+English, or possibly Canadian. A few judicious questions quickly brought out
+the information that she came from Liverpool and that she had three brothers in
+the British army. Carter decided that it was preposterous to suspect her of
+being in league with German agents. There was only one other thing that could
+have happened. Some one else—some one who had eluded Miss Strong’s notice—had
+removed the cipher message.
+</p>
+
+<p>
+Promptly he had telephoned to her to meet him. He was glad that he had done so,
+for her evident perturbation as she answered the ’phone both interested and
+puzzled him. Pausing just long enough to report to Chief Fleck, he hastened to
+the rendezvous, arriving there first. He selected a bench apart from the
+others, where the wall jutted out from the walk, and seating himself, idled
+there as if merely watching the river. In obedience with his instructions Jane,
+when she arrived, planted herself nonchalantly on the same bench, and paying no
+attention to him, pretended to be reading a letter.
+</p>
+
+<p>
+Presently Carter rose and stretching himself lazily, as if about to leave,
+turned to face the Drive, his keen eyes taking in all the passers-by.
+Apparently satisfied, he sat down abruptly and turned to speak to the girl
+beside him.
+</p>
+
+<p>
+“All right, K-19,” he said, “it’s safe. Now we can talk.”
+</p>
+
+<p>
+“I’ve got such a lot to tell,” cried Jane.
+</p>
+
+<p>
+“First,” said Carter, “just where did you put that cipher message when you put
+it back?”
+</p>
+
+<p>
+“What!” cried the girl, her face blanching, “wasn’t it there? Didn’t you find
+it?”
+</p>
+
+<p>
+Carter shook his head.
+</p>
+
+<p>
+“It must be there,” she insisted. “Are you sure you looked in the right
+book—the fifth book from the end on the second shelf on the up-town side of the
+store.”
+</p>
+
+<p>
+“It’s not there. I examined every book there, on the shelves above and below
+and at the other end, too.”
+</p>
+
+<p>
+“The clerk in the store, that girl—must have hidden it,” cried Jane with
+conviction.
+</p>
+
+<p>
+“That’s not likely. She’s an English girl—from Liverpool. She has three
+brothers fighting on the Allies’ side. We can leave her out of it.”
+</p>
+
+<p>
+“Who else could have taken it?”
+</p>
+
+<p>
+“There’s only one answer,” said Carter slowly and impressively. “Some one went
+into that store between the time you copied the message and the time I met you
+at the drug-store. You told me no one but a couple of girls had entered. Was
+there any one else? Think—think!”
+</p>
+
+<p>
+“There was no one,” said Jane thoughtfully, “no one except the two girls
+together. I never thought of suspecting them.”
+</p>
+
+<p>
+“What did they look like? Could you identify them?”
+</p>
+
+<p>
+“I did not notice them particularly,” Jane confessed. “I was expecting Mr.
+Hoff’s confederate to be a man.”
+</p>
+
+<p>
+“They’re using a lot of women spies,” asserted Carter. “Don’t you remember what
+the girls looked like?”
+</p>
+
+<p>
+“One of them,” said Jane thoughtfully, “wore an odd-shaped hat, a sort of a tam
+with a red feather.”
+</p>
+
+<p>
+“Would you know the hat again if you saw it?”
+</p>
+
+<p>
+“I think—I’m sure I would.”
+</p>
+
+<p>
+“Well, that’s something. Watch for that hat, and if you ever see it again trail
+the girl till you find out where she lives. If you locate her telephone Mr.
+Fleck at once. And now, what has happened to you?”
+</p>
+
+<p>
+“I’ve so much to tell, important, very important, I think.”
+</p>
+
+<p>
+She hesitated, wondering how much Carter was in the chief’s confidence. Did he
+know the import of the cipher message she had discovered? Ought she to talk
+freely to him?
+</p>
+
+<p>
+“Do you know what those numbers meant?” she asked.
+</p>
+
+<p>
+“Yes,” he replied, “about the eight transports sailing. The Chief told me about
+it.”
+</p>
+
+<p>
+“Well,” she said, with a sigh of relief, “I have become acquainted with young
+Mr. Hoff already. I’ve just had luncheon with him.”
+</p>
+
+<p>
+“That’s fine,” he cried enthusiastically. “A lucky day it was I ran across
+you.”
+</p>
+
+<p>
+“When you ’phoned me he was there in our apartment, he and a navy lieutenant,
+Mr. Kramer.”
+</p>
+
+<p>
+Attentively he listened as she told of the ruse by which she had inveigled them
+into coming to luncheon, reminding him that it was the same naval officer that
+he himself had seen in close conversation with Hoff at the Ritz the day before.
+He nodded his head in a satisfied way.
+</p>
+
+<p>
+“They are together too much to be up to any good,” he commented. “Tell me the
+rest. What made you so rattled when I ’phoned you?”
+</p>
+
+<p>
+He listened intently as she told of finding young Hoff standing right behind
+her as she had inadvertently mentioned aloud “the fifth book.”
+</p>
+
+<p>
+“Do you suppose,” she questioned anxiously, “that he overheard me and
+understood what we were talking about? He left right away after that. I do hope
+I didn’t betray the fact that they are being watched.”
+</p>
+
+<p>
+“We can’t tell yet,” said Carter. “The precautions they take and the roundabout
+methods they have of communicating with each other show that all Germany’s
+spies constantly act as if they knew they were under surveillance. In fact, I
+suppose every German in this country, whether he is a spy or not, can’t help
+but notice that his neighbors are watching him—and well they might.”
+</p>
+
+<p>
+“I don’t see why,” cried Jane, “Mr. Fleck did not have old Mr. Hoff locked up
+right away. He could not do any more damage then, or be sending any more
+messages about our transports.”
+</p>
+
+<p>
+“That wouldn’t have done the least bit of good,” said Carter decisively.
+“Watching our transports sail and spreading the news is only one of many of
+their activities. Somewhere in this country there is a master-council of German
+plotters, directing the secret movements of many hundreds, perhaps many
+thousands of spies and secret agents. They have their work well mapped out.
+They have men fomenting strikes in the government shipyards and stirring up all
+kinds of labor troubles. Others are busy making bombs and contriving diabolical
+methods of crippling the machinery in munition plants. A flourishing trade in
+false passports is being carried on, enabling their spies to travel back and
+forth across the Atlantic in the guise of American business men, ambulance
+drivers, Red Cross workers and what not. Still others of their agents are
+detailed to arrange for the shipping of the supplies Germany needs to neutral
+countries. By watching shipping closely they gather information, too, that is
+of value to the U-boat commanders. Every time there is any sort of activity
+against the draft, or peace meetings, or Irish agitation, we find traces of
+German handiwork. We have dismantled and sealed up every wireless plant we
+could find in America except those under direct government control, yet we are
+positive that every day wireless messages go from this country
+somewhere—perhaps to Mexico or South America, and from there are relayed to
+Germany, probably by way of Spain. Think of the enormous amount of money
+required to finance these operations and keep all these spies under pay. While
+we try to thwart their plans as we find them, all our efforts are constantly
+directed toward discovering who controls and finances their damnable system. We
+seldom if ever arrest any of the spies we track down, but keep watching,
+watching, watching, hoping that sooner or later the master-spy will be betrayed
+into our hands.”
+</p>
+
+<p>
+“You don’t think then,” said Jane disappointedly, “that old Mr. Hoff is one of
+the important spies.”
+</p>
+
+<p>
+“We can’t tell yet. He may be just one of the cogs—perhaps what they call a
+control-agent. We don’t know yet. Germany has been building up her spy system
+forty years, and it is ingenious beyond imagination. Her codes are the most
+difficult in the world. It took the French three years and a half to decipher a
+code despatch from Von Bethmann Hollweg to Baron von Schoen. By the time they
+had it deciphered in Paris the Germans had discovered what they were doing and
+had changed the code. It is seldom any one of the German spies knows much about
+the work that other spies are doing. The rank and file merely get orders to go
+and do such a thing, or find out about such a thing. Often they are not told
+what they are doing it for. They obey their orders implicitly in detail and
+make their reports, get new orders and go on to do something else. Only their
+master spy-council here knows what the summary of their efforts amounts to.
+Arresting old Hoff, or a dozen more like him, would not cripple them much.
+Other men would be assigned in their places, and the nefarious work would go
+on.”
+</p>
+
+<p>
+“I don’t know,” insisted Jane thoughtfully. “I believe that old Mr. Hoff is a
+far bigger spoke in the wheel than you think. I watched his face as I followed
+him this morning. He is a man of great intelligence, and I should judge a man
+of education.”
+</p>
+
+<p>
+“They’d hardly be using a man of that sort to carry messages,” objected Carter.
+“Maybe you’re right. We have not watched him long enough to find out. We’ve got
+nothing yet on the young fellow. Maybe he’s the real boss of the outfit. At any
+rate he is the one the Chief is anxious to have you keep tabs on. Are you to
+see him again?”
+</p>
+
+<p>
+“Oh, yes,” the girl answered quickly, a touch of color coming to her face, “I
+think so. I asked him to come to see me. I think—in fact I’m sure—he will. Do
+you want me to watch the bookshop to see if they leave any more messages
+there?”
+</p>
+
+<p>
+“No,” said Carter. “I’ve got one of my men assigned to that. You keep after the
+young fellow. Say, does your father keep an automobile?”
+</p>
+
+<p>
+“Yes, but it’s been put up for the winter. We’re going to bring it out as soon
+as Dad can find a chauffeur. Our man—the one we had last year—has been drafted,
+and good chauffeurs are scarce now. Why did you ask?”
+</p>
+
+<p>
+“I’ll find you a chauffeur,” said Carter decisively.
+</p>
+
+<p>
+“You mean”—Jane hesitated—“a detective?”
+</p>
+
+<p>
+Carter grinned.
+</p>
+
+<p>
+“An agent like you and me. K-27 is an expert chauffeur and mechanic with fine
+references. His last job was with the British High Commission, and they gave
+him good testimonials.”
+</p>
+
+<p>
+“What do you want him to do?”
+</p>
+
+<p>
+“Driving the Strong car makes a good excuse for him to be around without
+exciting suspicion. He might even come up-stairs once in a while to get orders
+or do little repair jobs around the apartment. Some day, supposing the people
+next door were all out, he might even succeed in planting a dictograph so that
+you could sit there in your room and hear all that was going on and what the
+Hoffs talked about. That would help a lot. If ever he was caught prowling about
+the hall, the fact that he was your chauffeur would provide him with an alibi.
+Do you think you can fix it up with your father?”
+</p>
+
+<p>
+“I’m sure of it. When can he come?”
+</p>
+
+<p>
+“The sooner the better—to-night—to-morrow.”
+</p>
+
+<p>
+“I’ll tell Dad at dinner to-night that I’ve learned of a good chauffeur and
+have asked him to come in at eight this evening.”
+</p>
+
+<p>
+“Fine,” said Carter. “He’ll be there. And don’t forget to report once a day to
+the Chief.”
+</p>
+
+<p>
+“I won’t.”
+</p>
+
+<p>
+“And if anything unexpected turns up,” said Carter, “and you need help, take a
+good look at that nurse that is passing.”
+</p>
+
+<p>
+Jane turned curiously to inspect a buxom girl in a drab nurse’s costume who was
+wheeling a baby carriage along the sidewalk near-by. Seeing herself observed
+the girl stopped, and at a sign from Carter wheeled her charge up to where they
+were standing.
+</p>
+
+<p>
+“K-22,” said Carter, “I want to introduce you to K-19.”
+</p>
+
+<p>
+Gravely the two girls, nodding, inspected each other.
+</p>
+
+<p>
+“She always wears a blue bow at her neck,” Carter added, “so you can recognize
+her by that.”
+</p>
+
+<p>
+The girl smilingly nodded again and wheeled the carriage on up the Drive.
+</p>
+
+<p>
+“Who is she?” Jane asked eagerly, turning to Carter.
+</p>
+
+<p>
+“Just K-22,” said the agent, “and all she knows about you is that you are K-19.
+That’s the way we work in the service mostly. The less one operative knows
+about another the better, for what you don’t know you can’t talk about.”
+</p>
+
+<p>
+“Doesn’t she even know my name?” persisted Jane.
+</p>
+
+<p>
+“She may have found it out for herself while she has been watching the Hoffs,
+but we didn’t tell her. Nobody in the service knows who you are except the
+Chief and myself—and of course K-27 will have to know if he takes the
+chauffeur’s job.”
+</p>
+
+<p>
+“What is his name?”
+</p>
+
+<p>
+“I don’t know yet,” said Carter gravely. “I haven’t seen his references, so I
+don’t know what name they are made out in. You can find out what to call him
+when he reports to-night. You’ll see that he gets the job?”
+</p>
+
+<p>
+“Indeed I will,” answered Jane, experiencing a sense of relief at the prospect
+of having some one at hand in the household with whom she could discuss her
+activities.
+</p>
+
+<p>
+And as she had anticipated she had little difficulty in interesting her father
+in the subject of a new chauffeur. Mr. Strong for several days had been trying
+to find one without success.
+</p>
+
+<p>
+“You say this man’s last place was with the British High Commission.”
+</p>
+
+<p>
+“Some one of the girls was telling me,” she prevaricated. “I asked her to tell
+him to come here to-night at eight. He ought to be here any minute.”
+</p>
+
+<p>
+Presently the candidate for the place was announced.
+</p>
+
+<p>
+“Mr. Thomas Dean to see about a chauffeur’s position,” the maid said as she
+brought him in, and while her father questioned him, Jane studied him
+carefully.
+</p>
+
+<p>
+He could not be more than thirty, she decided, and the voice in which he
+answered her father’s questions was surely a cultivated one. It would not have
+surprised her in the least to have learned that he was a college man. Even in
+his neat chauffeur’s uniform he seemed every inch a gentleman. He had been
+driving a car for twelve years, he explained. No, he did not drink and had
+never been arrested for speeding.
+</p>
+
+<p>
+“Are you a married man?”
+</p>
+
+<p>
+Jane listened curiously for his answer to this question of her father’s. Surely
+it would be far more interesting if he wasn’t. Of course, he was a chauffeur
+and a detective, but somehow she could not help feeling, perhaps because of his
+easy manner, that more than likely most of the cars he had driven were cars
+that he himself had owned. K-27 she decided was going to be quite a
+satisfactory partner to work with.
+</p>
+
+<p>
+“There’s just one thing,” said her father. “You say you are not married. I
+can’t understand why it is that you are not in the army.”
+</p>
+
+<p>
+“I am not eligible,” said Thomas Dean calmly, though Jane thought she could
+detect a twinkle in his eye. “One of my legs has been broken in three places.”
+</p>
+
+<p>
+“But there are things a young fellow can do for his country besides marching,”
+insisted Mr. Strong. “The government needs mechanics, too.”
+</p>
+
+<p>
+“I know,” said Thomas Dean, almost humbly, “but I have a mother, and my father
+is dead.”
+</p>
+
+<p>
+Jane smiled a little to herself at his answer. She noted how carefully he had
+avoided saying anything about having a mother to support. It would not have
+surprised her in the least to have learned that he was a millionaire, yet her
+father, ordinarily shrewd in judging men, apparently was satisfied.
+</p>
+
+<p>
+“Supporting a mother, I suppose, comes first,” he said. “Well, Dean, when can
+you come?”
+</p>
+
+<p>
+“To-morrow morning if you like,” the new chauffeur answered, nodding gravely to
+Jane as he withdrew.
+</p>
+
+<p>
+Mr. Strong, as soon as they were alone, spoke enthusiastically about the young
+man, complimenting Jane on having discovered him, and as he did so a revulsion
+of feeling swept over her. For the first time she realized into what duplicity
+her work for the government was leading her. She had pledged her word to Chief
+Fleck that she would keep her activities an absolute secret even from her
+parents. Already she was deceiving them, bringing into the household an
+employee who really was a detective, a spy. She was tempted to tell her father,
+at least, what she was doing. He, she knew, was filled with a high spirit of
+patriotism. While he might not wholly approve of what she herself was doing she
+might be able to convince him of the necessity of it. If she could only tell
+him, her conscience would not trouble her, but there was her promise—her sacred
+promise; she couldn’t break that.
+</p>
+
+<p>
+While with troubled mind she debated with herself between her duty to her
+parents and her duty to her country, one of the maids came in with a box of
+flowers for her.
+</p>
+
+<p>
+Eagerly she cut the string and opened the box. Chief Fleck especially wanted
+her to cultivate young Hoff’s acquaintance. If her suspicion as to the sender
+were correct, she could feel that she had made an auspicious beginning.
+</p>
+
+<p>
+In a tremor of excitement she snatched off the lid of the box and tore out the
+accompanying card from its envelope.
+</p>
+
+<p>
+“Mr. Frederic Johann Hoff,” it read, “in appreciation of a most profitable
+afternoon.”
+</p>
+
+<p>
+Wondering at the peculiar sentiment of the card she tore off the enclosing
+tissue paper from the flowers. Orchids, wonderful, delicately tinted orchids,
+nestled in a sheaf of feathery green fern—five of them.
+</p>
+
+<p>
+“Five orchids—the fifth book—a profitable afternoon.”
+</p>
+
+<p>
+Jane felt sure now she had betrayed the government’s watchers to at least one
+of the watched.

+<h2><a name="CHAPTER_VII"></a>CHAPTER VII<br/>
+THE WOMAN ON THE ROOF</h2>
+
+<p>
+It is amazing how much information on any given subject any one—even a wholly
+inexperienced person like Jane Strong—can acquire within a few days when one’s
+mind is set resolutely to the task. It is much more amazing how much one can
+learn when aided and abetted by an experienced chauffeur, or more properly
+speaking a mysterious and cultured secret service operative, masquerading as an
+automobile driver.
+</p>
+
+<p>
+Who Thomas Dean was, why he was in the secret service, and what his real name
+was, were questions that kept perpetually puzzling Jane. In the presence of her
+father and mother, so skilful an actor was he that it was hard to believe him
+anything but what he appeared to be, a respectful, intelligent and prompt young
+man who knew the traffic regulations and the anatomy of automobiles. When he
+and Jane were by themselves he invariably threw off his mask to some extent. He
+became the director instead of the directed, though never letting anything of
+the personal relation creep in. That he was college-bred, Jane felt certain. He
+spoke both German and French much better than she did. He occasionally used
+words that no ordinary chauffeur would be likely to know the meaning of.
+Sharing the secret of such a mission as theirs, they quickly found themselves
+on a friendly basis, yet the girl hesitated whenever her curiosity prompted her
+to try to find out anything that would reveal his identity. There was always
+present the feeling that any exhibition of undue curiosity on her part would be
+a disappointment to her employer. The chief disapproved of curiosity except on
+one subject—what the Germans were doing.
+</p>
+
+<p>
+Many things Jane and her aide learned about the Hoffs in the days following
+Thomas Dean’s coming, reporting them all as directed. Of how much or of how
+little value her discoveries were Jane had no means of knowing. Chief Fleck
+seemed satisfied but was always urging her to acquire more information and more
+details, always details. Dean, too, had seconded the warning about observing
+even what seemed to be insignificant trifles.
+</p>
+
+<p>
+“Most of the Germans,” he said to her, “you will find are very methodical. They
+like to do things according to schedule. For instance, I learned yesterday that
+old Hoff and his nephew frequently go off on all-day automobile trips. They
+always go on Wednesday.”
+</p>
+
+<p>
+“Are they going to-morrow?”
+</p>
+
+<p>
+“The presumption is that they will. They have done so every Wednesday for six
+weeks.”
+</p>
+
+<p>
+“Can’t we follow them in our car?” cried the girl, “and see what they are up
+to?”
+</p>
+
+<p>
+Dean shook his head.
+</p>
+
+<p>
+“The Chief is looking out for that. There is more important work for us to do
+right here. I want to try to install a dictograph in their apartment.”
+</p>
+
+<p>
+“How exciting.”
+</p>
+
+<p>
+“You must find some excuse for me to come up into your apartment and see to it
+that none of your people are about.”
+</p>
+
+<p>
+“That will be easy. Mother and Aunt will be out all day, and it is cook’s
+afternoon off. I can easily send the maids out.”
+</p>
+
+<p>
+“But that’s not all. There is the Hoffs’ servant to be disposed of.”
+</p>
+
+<p>
+“I don’t see how I can manage that,” said Jane. She could think of no possible
+way of overcoming that difficulty.
+</p>
+
+<p>
+“She’s an old German woman—Lena Kraus,” continued Dean. “I’ve found out that
+she always washes on Wednesdays. When she goes up on the roof in the afternoon
+to get the clothes will be our time. It will be your job to see that she stays
+there until I am through. It will not take me more than half an hour.”
+</p>
+
+<p>
+“But what will I do if she starts to come down? How will I stop her?”
+</p>
+
+<p>
+“You’ll have to use your wits. Keep her talking as long as you can. When she
+starts down come with her. Press the elevator button four times. I’ll leave the
+door of the Hoff apartment open and very likely will hear it in time to get
+away.”
+</p>
+
+<p>
+“But how’ll you get their door open?”
+</p>
+
+<p>
+Dean smilingly drew forth a key.
+</p>
+
+<p>
+“I borrowed the superintendent’s bunch last night, pretending I had lost the
+key to my locker in the basement. I knew he had a master-key that unlocks all
+the apartment doors, and there was no trouble in picking it out. I had some wax
+in my hand and made an impression of it right under his nose.”
+</p>
+
+<p>
+“How clever,” cried Jane, “but suppose the Hoffs do not go off to-morrow. What
+will we do then?”
+</p>
+
+<p>
+“You are taking tea with young Hoff this afternoon, aren’t you?”
+</p>
+
+<p>
+“Yes,” said Jane, “that is, he asked me to. I am to meet him at the Biltmore at
+five.”
+</p>
+
+<p>
+“When you’re with him propose doing something together to-morrow afternoon. See
+what he says.”
+</p>
+
+<p>
+“That’s an excellent idea. I’ll ask him to go to the matin&eacute;e with me.”
+</p>
+
+<p>
+“That will do splendidly. Has he been with that navy officer lately?”
+</p>
+
+<p>
+“Not since Sunday, to my knowledge. I wonder if old Mr. Hoff has left any more
+cipher messages at the bookshop?”
+</p>
+
+<p>
+“No,” said Dean, “he hasn’t. The place has been constantly watched, but he
+hasn’t been near it since that first day.”
+</p>
+
+<p>
+“I’m afraid,” sighed Jane despondently, “I betrayed the fact that we were
+watching them to the nephew. He overheard me talking to Carter about the ‘fifth
+book,’ and of course he knew what it meant. I’m certain the old man is still
+reporting about our transports. Every day I can hear some one telephoning to
+him. He waits for the message, and then he goes out.”
+</p>
+
+<p>
+“He certainly is expert in eluding shadowers,” admitted Dean. “Every day he has
+been followed, but always he manages to give the operatives the slip. He must
+know he is being watched.”
+</p>
+
+<p>
+“I’m anxious to know what the nephew will say to me to-day,” said Jane. “I know
+he knows what I am doing. He looks at me in such an amusedly superior way every
+time he sees me.”
+</p>
+
+<p>
+“Be careful about trying to pump him,” cautioned Dean. “He strikes me as by far
+the more intelligent of the two. It would not surprise me in the least if he
+were not old Hoff’s nephew at all, but really his superior, sent over
+especially by Wilhelmstrasse to take charge of the plotters. He doesn’t in the
+least resemble old Hoff.”
+</p>
+
+<p>
+“No indeed, he doesn’t,” admitted Jane. “He certainly is clever, too. We
+haven’t learned a single thing that incriminates him, have we?”
+</p>
+
+<p>
+“Nothing definite, yet everything taken together looks damaging enough. Here is
+a young German of military age and appearance, who arrived from Sweden just
+before we went into the war. He has plenty of money and spends his time idling
+about New York, in frequent communication with at least one navy officer. He
+selects a home overlooking the river from which our soldiers are departing for
+France. You yourself saw him pursuing K-19—the other K-19—who a few hours
+afterward was found murdered.”
+</p>
+
+<p>
+“Things don’t look right,” Jane agreed, yet a few hours later as she sat
+opposite the young man at tea, she found herself doubting. It seemed
+incredible, impossible, that Frederic Hoff could be a murderer. Her instinctive
+sense of justice forced her to admit that it was hard for her to believe him
+even a spy. He seemed so cultured, so clean, so straightforward, so nice. If
+she had not seen that unforgettable look of hate on his face that night as she
+watched him from the window she could not, she would not have believed evil of
+him.
+</p>
+
+<p>
+The tremor of nervous excitement in which she met him quickly passed, and she
+found herself once more chatting intimately with him and enjoying it. He talked
+well on practically all subjects, showing reserve only when she tried to draw
+him out about himself. Her previous experiences with the opposite sex had
+taught her that most men’s favorite topic of conversation is themselves, but
+Mr. Hoff appeared to be the exception. Adroitly he baffled all her efforts to
+get him to discuss his family, his achievements, or his past, even when she
+sought to encourage intimacy by telling about her brother who was abroad in
+Pershing’s army.
+</p>
+
+<p>
+“You must let me be your big brother while he is away,” her escort had
+suggested gallantly.
+</p>
+
+<p>
+“All right, brother,” she had challenged him. “I’ll take you on at once. I have
+seats for a matin&eacute;e to-morrow. I’d much rather go with a brother than
+with one of the girls.”
+</p>
+
+<p>
+“I would be delighted,” he answered unsuspectingly, “but unfortunately I have
+an engagement that takes me out of town.”
+</p>
+
+<p>
+“We’ll go next week, then—Wednesday.”
+</p>
+
+<p>
+“A week is too long to wait. Let me take you to a matin&eacute;e on Saturday.”
+</p>
+
+<p>
+Jane hesitated. At times her conscience troubled her not a little. While
+satisfied that the importance of her trust wholly justified her actions, she
+disliked any deception of her family.
+</p>
+
+<p>
+“Wouldn’t it be better,” she parried, “if you came to call on me some evening
+first? You’ve only just met my mother, and I would like you to know Dad, too.”
+</p>
+
+<p>
+“May I?” he cried with manifest pleasure. “How about to-morrow evening?”
+</p>
+
+<p>
+“That’s Wednesday,” she answered slowly. That was the day she and Dean were
+planning to put in a dictograph. She wondered at herself calmly carrying on
+this casual conversation with the man she was planning to betray. Coloring a
+little from the very shame of it, she continued, “How about making it Thursday
+evening?”
+</p>
+
+<p>
+“Delighted,” cried Hoff, “and about Saturday’s matin&eacute;e—what haven’t you
+seen?”
+</p>
+
+<p>
+Glad for the respite of at least twenty-four hours, Jane, as they talked,
+watched his face, his expression, his eyes. Regardless of the things she
+believed about him, he impressed her as honest and sincere. Certainly there was
+no mistaking the fact that his liking for her and his delight in her society
+were wholly genuine. Her heart warned her that it was his intention to press
+their new-formed acquaintance into close intimacy. Was he, she wondered, like
+herself, pretending friendship merely to unmask secrets for his government? No,
+she could not, she would not believe it. She felt sure that his admiration was
+unfeigned. Something told her that quickly his ardor and determination might
+lead her into embarrassing circumstances. He might even ask her to marry him.
+For a moment she was overcome with timidity and tempted to stop short on her
+new career, but there came to her the thought of the brave Americans in the
+trenches, of the soldiers at sea, of the brutal, lurking U-boats, and sternly
+she put aside all personal considerations.
+</p>
+
+<p>
+“You spoke of going out of town,” she said when the subject of the
+matin&eacute;e had been disposed of. “Don’t you find train travel rather
+disagreeable these days?”
+</p>
+
+<p>
+“Fortunately I’m motoring.”
+</p>
+
+<p>
+“That will be nice, if you don’t have to travel too far.”
+</p>
+
+<p>
+“It is quite a distance for one day, but I am used to it. I make the trip
+often.”
+</p>
+
+<p>
+Feeling that at least she had learned something, Jane rose to go. She knew that
+both the Hoffs would be out of the way to-morrow. The inference from his last
+remark was that they were going to the same place they had gone on previous
+Wednesdays. That was something to report to Mr. Fleck.
+</p>
+
+<p>
+“My car is outside,” she said as they rose. “Can’t I take you home?”
+</p>
+
+<p>
+“Sorry,” said her host, “but I am dining here to-night. Lieutenant Kramer is to
+join me.”
+</p>
+
+<p>
+“Remember me to him,” she said as he escorted her to the automobile, driven by
+Dean.
+</p>
+
+<p>
+A block away from the hotel she tapped on the glass, and as Dean brought the
+car to a stop she climbed into the seat beside him. Only a week ago she would
+have criticized any girl who rode beside the chauffeur. In fact she had spoken
+disapprovingly of a girl in her own set who made a habit of doing it, but now
+she never gave it a thought. Many things in her life seemed to have assumed new
+aspects and values since she had entered on a career of useful activity. In her
+was rapidly developing something of her father’s ability and directness. As she
+wanted to talk confidentially with Dean, she went the easiest way about it,
+entirely regardless of appearances.
+</p>
+
+<p>
+“Apparently you carried it off well,” he commented.
+</p>
+
+<p>
+“I hope so,” she answered, coloring a little. “They’re making their usual
+Wednesday motor trip.”
+</p>
+
+<p>
+“He did not tell you their destination?”
+</p>
+
+<p>
+“No, but Lieutenant Kramer is dining with him to-night at the Biltmore.”
+</p>
+
+<p>
+“Fine. Those things the Chief can take care of. That leaves the way clear for
+us to-morrow afternoon.”
+</p>
+
+<p>
+“What excuse will I make for having you come up to the apartment?”
+</p>
+
+<p>
+“You want me to change some pictures. That will account for the wire if I’m
+caught.”
+</p>
+
+<p>
+“I hope no one sees you.”
+</p>
+
+<p>
+“Nobody’ll see me but the elevator man, and he’ll think nothing of it.”
+</p>
+
+<p>
+Apparently, too, Dean was right, for the next afternoon he entered the Strong
+apartment carrying a suitcase in which was concealed his apparatus and the
+necessary wire.
+</p>
+
+<p>
+“Hurry,” cried Jane, who was waiting for him. “The Hoffs’ maid has just gone up
+on the roof.”
+</p>
+
+<p>
+“We can safely give her at least a few minutes,” said Dean setting to work to
+make a hole through the wall into the apartment adjoining. Just as he had
+finished making it and had pushed one end of the wire through, the telephone
+bell rang, and Jane in dismay sprang to answer it.
+</p>
+
+<p>
+“Disguise your voice,” warned Dean. “If it is a caller say there is no one
+home.”
+</p>
+
+<p>
+“It was Lieutenant Kramer calling,” said Jane as she returned.
+</p>
+
+<p>
+“Did he recognize your voice?”
+</p>
+
+<p>
+“I don’t think so.”
+</p>
+
+<p>
+“What did he say?”
+</p>
+
+<p>
+“He said to tell Miss Strong that he had called.”
+</p>
+
+<p>
+“Then he didn’t suspect you.”
+</p>
+
+<p>
+“Isn’t there danger, though, that he may come up to the Hoff apartment?”
+</p>
+
+<p>
+Dean sprang to the window and looked out at the street below.
+</p>
+
+<p>
+“No, there he goes up the street. He evidently did not try to see if the Hoffs
+were at home. That’s funny.”
+</p>
+
+<p>
+“Why funny?”
+</p>
+
+<p>
+“It means of course that he, too, knows about those Wednesday trips the Hoffs
+make.”
+</p>
+
+<p>
+Cautiously he opened the door into the public hall. There was no one about.
+Catlike in swiftness and silence he moved to the Hoff door and inserted his
+new-made key. It worked perfectly.
+</p>
+
+<p>
+“Now,” he whispered to Jane, “to the roof—quick. I must not be taken by
+surprise. Give me at least ten minutes more—fifteen if you can.”
+</p>
+
+<p>
+Quickly he passed inside, closing the door behind him all but a barely
+noticeable crack, as Jane rang for the elevator and bade the operator take her
+to the roof. As she emerged there and stood waiting for the elevator to descend
+again, an ornamental lattice screened her from the rest of the roof. Cautiously
+and curiously she peered between the slats, trying to see what the Hoff servant
+was doing at the moment. She decided that she would not reveal her presence
+until the woman made ready to go down-stairs.
+</p>
+
+<p>
+As from behind her screen she scanned the roof she espied old Lena over on the
+side next the river bending over a half-filled basket of clothes, apparently
+putting into the basket some of the freshly dried laundry from the lines
+extending all over the roof. As Jane watched her the old woman straightened
+herself up and cast a cautious glance about. Apparently satisfied that she was
+alone she whipped out something from a pocket in her apron and turned in the
+direction of the river.
+</p>
+
+<p>
+Jane gasped in amazement, a thrill of excitement sweeping over her at this new
+discovery. It was plain that the old servant was studying the transports in the
+river below through a pair of powerful field glasses. Curiously Jane observed
+her, wondering what she was trying to ascertain, wondering if through the
+glasses she was able to identify the battleships and other boats. Old Lena’s
+next move was still more puzzling. Hastily dropping her glasses into the basket
+she began to hang again on the line some of the clothes. They were
+handkerchiefs, Jane noted interestedly, one large red one, and the rest white,
+some large, some small, a whole long row of nothing but handkerchiefs.
+</p>
+
+<p>
+All at once it came to Jane what it must mean. The arrangement of the
+handkerchiefs must be some sort of a code. She studied the way they were
+placed, committing the order to memory. “Red—two large—one small—one large—one
+small.” Of course it was a code, a signal to some one aboard one of the ships.
+</p>
+
+<p>
+The line of handkerchiefs completed old Lena once more took up her glasses,
+first looking around as before to see if any one were on the roof. How Jane
+wished that she, too, could see the ships from where she stood. Was some
+traitor in the navy wigwagging to the old woman? She was tempted to spring
+forward and seize her and stop this dastardly signalling, but she remembered
+her duty. She was there to see that Dean was not surprised by old Lena’s
+return. So long as the woman kept signalling he was safe.
+</p>
+
+<p>
+Once more the laundress dropped her glasses and began frantically rearranging
+the handkerchiefs. Again Jane noted their order—red—two small—one large—three
+small—two large. Again the laundress resorted to the glasses, and at last,
+apparently satisfied, began taking down the rest of the laundry and making
+ready to leave the roof. Trying to act as if she had just arrived, Jane stepped
+boldly forward.
+</p>
+
+<p>
+“I wonder,” she said approaching the woman, “if you can tell me where I can
+find a good laundress.”
+</p>
+
+<p>
+“<i>Nicht versteh</i>” said old Lena, eyeing her suspiciously and hostilely,
+and at the same time attempting to pass her with the basket of clothes.
+</p>
+
+<p>
+Deliberately blocking the way, Jane repeated her question, this time in German,
+feeling thankful that her language studies at school were not wholly forgotten
+and that they had included such practical phrases as those required to hire and
+discharge maids and complain about the quality of their work.
+</p>
+
+<p>
+“I know no one,” the old woman answered her, this time in English.
+</p>
+
+<p>
+Jane breathed fast with excitement. The laundress’ slip of the tongue, after
+denying that she understood, was evidence in itself of her deliberate
+duplicity. Realizing her mistake, the old woman now sullenly refused to answer
+any questions, merely shaking her head and trying to dodge past and escape.
+</p>
+
+<p>
+To prolong the questioning, Jane felt, would be only to arouse suspicion, and
+reluctantly she allowed old Lena to precede her to the elevator, anticipating
+her, however, in ringing the bell, pressing the button four times as Dean had
+directed. As they descended together she was almost in a panic. How long had
+she kept the laundress on the roof? She really had no idea. She had been so
+absorbed in her new discovery she had given no thought to the time. For all she
+knew she might have been there only five minutes. Had Dean had time to finish
+his work?
+</p>
+
+<p>
+Almost frenzied with anxiety, wondering if it were too soon, she moved forward
+in the car so as to obstruct old Lena’s view through the door as it opened. One
+glance showed her the Hoff door now tightly closed, and she thought she heard
+the door of her own apartment just closing. Suddenly she remembered that she
+had gone up on the roof without a key. It would be a pretty pass if Dean were
+still in the Hoff apartment and she couldn’t get into her own.
+</p>
+
+<p>
+All in a tremble she pressed the button of her own door, waiting, however, to
+see that the laundress was out of the hall. It was Dean who opened the door,
+and she all but fainted in his arms as she saw that he was back in safety.
+</p>
+
+<p>
+“It’s done,” he cried gleefully, as he caught her and drew her within, closing
+the door carefully behind her. “I just finished my work as you came down.”
+</p>
+
+<p>
+Great drops of perspiration still stood on his forehead and he was breathing
+rapidly.
+</p>
+
+<p>
+“Why, what’s the matter?” he cried, noticing for the first time Jane’s
+perturbation. “Was it too much for you? What happened?”
+</p>
+
+<p>
+“Put this down quick, quick,” gasped Jane, “Red—two large—one small—one
+large—one small—and then—red—two small—one large—three small—two large.”
+</p>
+
+<p>
+Wonderingly he complied, jotting down what she told him in his notebook, and
+turning to ask her what it meant, discovered that she had fainted.

+THE LISTENING EAR</h2>
+
+<p>
+“I don’t know what is the matter with Jane,” sighed Mrs. Strong a few days
+after the employment of the new chauffeur.
+</p>
+
+<p>
+“She’s not ill, is she?” responded her husband. “I never saw her looking more
+fit.”
+</p>
+
+<p>
+“She looks all right,” said her mother. “It is the peculiar way she is acting
+that bothers me. She spends hours and hours moping in her room, and then there
+are times when she takes notions of going out and is positively insistent that
+she must have the car.”
+</p>
+
+<p>
+“Maybe she’s in love,” suggested Mr. Strong, resorting to the common masculine
+suspicion.
+</p>
+
+<p>
+“With whom?” retorted his wife indignantly. “I don’t believe there is an
+eligible man under forty in all New York. None of the men are thinking about
+marriage these days. They all want to go to France, even the married ones. I
+believe you’d go yourself if you were a few years younger.”
+</p>
+
+<p>
+“I certainly would,” announced her husband enthusiastically.
+</p>
+
+<p>
+“Jane tells me she is writing a novel,” Mrs. Strong continued, “and that’s why
+she stays in her room so much. I hope she won’t turn out to be literary.”
+</p>
+
+<p>
+“Don’t worry,” advised Mr. Strong. “With all the men off to war you’ll find
+young women doing all kinds of funny things to work off their energy. If a girl
+can’t be husband-hunting, she’s got to be doing something to keep busy. There
+are worse things than trying to write novels. Jane is all right. Let her
+alone.”
+</p>
+
+<p>
+So, even though her mother’s suspicions had been aroused, the girl in the next
+few days managed to spend many hours with her ears glued to the receiver of the
+dictograph without being discovered. In the Hoffs’ apartment Dean had succeeded
+in locating it over the dining-room table, concealed in the chandelier, and in
+Jane’s room the other end rested in the back of a dresser drawer that she
+always carefully locked when absent.
+</p>
+
+<p>
+The novelty of listening for bits of her neighbors’ conversation quickly wore
+off. To sit almost motionless for hours listening, listening intently for every
+sound, hearing occasional words spoken either in too low tones or too far
+distant to make them understandable, to record bits of conversation that
+sounded harmless, yet might have some sinister meaning, became a most laborious
+task. Yet persistently Jane stuck at it. The greater knowledge she gained of
+the plottings of the German agents, the more important and vital she realized
+it was for every clue to be diligently followed in the hope that the trail
+might at last reach the master-spy, whose manifold activities were menacing
+America.
+</p>
+
+<p>
+In general she was disappointed with the results of her listening. To be sure
+they had furnished indisputable evidence of something they already had
+ascertained—that old Hoff, despite being a naturalized American, still was a
+devoted adherent of the ruler of Germany. Nightly as he and his nephew sat down
+to dinner she could hear his gruff, unpleasant voice ceremoniously proposing
+always the same toast:
+</p>
+
+<p>
+“Der Kaiser!”
+</p>
+
+<p>
+Even when the younger Hoff was dining out, as he sometimes did, Jane could hear
+the old man giving the toast, presumably with only the old servant for an
+auditor. That the woman, too, was a spy, as well as servant, Jane had known
+since the day on the roof, but so far neither she nor Dean had been able to
+make anything out of her handkerchief code, though both were sure the messages
+related to the sailings of transports.
+</p>
+
+<p>
+Only once had she heard anything that she deemed really important. One evening,
+as uncle and nephew dined, there had been an acrimonious dispute.
+</p>
+
+<p>
+“Have you it yet?” the uncle had asked in German.
+</p>
+
+<p>
+“Not yet,” Frederic had answered.
+</p>
+
+<p>
+His seemingly simple reply for some reason appeared to have stirred the elder
+man’s wrath. He broke into a volley of curses and epithets, reproaching his
+nephew for his delay. In the rapid medley of oaths and expostulations Jane
+could distinguish only occasional words—“afraid”—“haste”—”all-highest
+importance”—“American swine.” The younger Hoff had appeared to exercise
+marvelous self-control.
+</p>
+
+<p>
+“There is yet time,” he answered calmly.
+</p>
+
+<p>
+“Donnerwetter,” the old man had exclaimed. “There is yet time, you say—and Emil
+the wonder-worker almost ready has. It must be done at once.”
+</p>
+
+<p>
+The outburst over, old Hoff had subsided into inarticulate mutterings,
+evidently busy with his food, leaving Jane to wonder futilely who Emil might
+be, what he meant by the “wonder-worker,” and what particular task had been
+assigned to the nephew that must be performed immediately. She had hastened to
+report this conversation in detail to Chief Fleck, but if he understood what it
+was about he had taken neither Jane nor Thomas Dean into his confidence.
+</p>
+
+<p>
+Other things, too, Jane had learned and reported, which she knew the chief
+appreciated even though he was sparing in his thanks and compliments. She had
+learned through her almost constant listening that Lieutenant Kramer was a
+regular visitor, coming to the Hoff apartment or seeing Frederic Hoff somewhere
+every other day. Unfortunately he was always conducted into one of the inner
+rooms, so that no more of the conversation than the ordinary greetings and
+farewells ever reached Jane’s ears. The mere fact of his coming so regularly to
+the Hoffs convicted him of treachery, in Jane’s mind. What proper business
+could an American naval officer have in the home of two German agents? The
+excuse that Frederic Hoff was a delightful and entertaining friend was entirely
+too flimsy and unsatisfactory.
+</p>
+
+<p>
+Nothing that she had overheard—and within her heart she felt glad that it was
+so—in any way as yet incriminated young Hoff. When she dared to think about it,
+she found herself almost believing, certainly at least wishing, that the nephew
+was not involved in his uncle’s activities. Most of his time, in fact, was
+spent out of the apartment. He frequently went out early in the morning, not
+returning until the early hours of the next morning. The old man, on the
+contrary, always stayed at home until eleven o’clock. At that hour his
+telephone would ring. The telephone was located near the dining room, so Jane
+could easily hear his conversations. Invariably some brief message was given to
+him, a name, which he repeated aloud as if for verification.
+</p>
+
+<p>
+As Jane overheard them she had set them down:
+</p>
+
+<p class="letter">
+Thursday—“Jones.”<br/>
+Friday—“Simpson.”<br/>
+Saturday—“Marks.”<br/>
+Sunday—“Heilwitz.”<br/>
+Monday—“Lilienthal.”<br/>
+Tuesday—“Wheeler.”
+</p>
+
+<p>
+As she sat by the hour listening Jane kept pondering over these names. What
+could they mean? Were they, too, a code of some sort? Always, as soon as this
+word had come to him, old Hoff went out. Could they be, she wondered, passwords
+by which he gained access somewhere to government buildings or places where
+munitions were being made or shipped?
+</p>
+
+<p>
+Meanwhile her acquaintance with Frederic Hoff had been progressing rapidly. As
+she had suggested he had called on her and had been presented to her father,
+and on the next Saturday they had gone to a matin&eacute;e together. She had
+been eager to see what her father thought of him, for Mr. Strong, she knew, was
+regarded as a shrewd judge of men.
+</p>
+
+<p>
+“What does that young Hoff do who was here last night?” her father had asked at
+the breakfast table.
+</p>
+
+<p>
+“He’s in the importing business with his uncle, I think,” she had answered.
+</p>
+
+<p>
+“Where’d you meet him?”
+</p>
+
+<p>
+“He lives in the apartment next door. Lieutenant Kramer introduced him.”
+</p>
+
+<p>
+“He’s German, isn’t he?”
+</p>
+
+<p>
+“Oh, no,” said Jane, almost unconsciously rallying to defend him, “he was born
+in this country.”
+</p>
+
+<p>
+“Well, it’s a German name.”
+</p>
+
+<p>
+“Don’t you like him?”
+</p>
+
+<p>
+“He talks well,” her father said, “and seems to be well-bred.”
+</p>
+
+<p>
+It was with reluctance, too, that Jane admitted to herself that the better
+acquainted she became with Frederic Hoff the more fascinating she found his
+society. She was always expecting that by some word or action he would reveal
+to her his true character. At the matin&eacute;e she had waited anxiously to
+see what he would do when the orchestra played the national anthem. To her
+amazement he was on his feet almost among the first and remained standing in an
+attitude of the utmost respect until the last bar was completed. If he were
+only pretending the r&ocirc;le of a good American, he certainly was a wonderful
+actor. As her admiration for him increased and her interest in him grew she
+found that almost her only antidote was to try to keep thinking of his face as
+she had seen it the night that K-19—the other K-19—had been so mysteriously
+murdered. She kept wondering if Chief Fleck had made any further discoveries
+about the murder and resolved to ask him about it at the first opportunity. She
+therefore was delighted when on Tuesday, as she made her regular report by
+telephone, he asked if she could come to his office that afternoon with Dean to
+discuss some matters of importance. They found Carter already with the chief
+when they arrived.
+</p>
+
+<p>
+“Thanks to your work, Miss Strong, and to Dean’s dictograph,” said the chief,
+“we have made considerable progress. We have learned a lot more about the
+cipher messages.”
+</p>
+
+<p>
+“You have learned it through me,” cried Jane in amazement.
+</p>
+
+<p>
+“Yes,” said the chief, smiling, “from that list of names you reported.”
+</p>
+
+<p>
+“What were they, a cipher, a code?” questioned the girl breathlessly.
+</p>
+
+<p>
+“No, nothing like that. They are merely the names of various innocent and
+unsuspecting booksellers in various parts of the city.”
+</p>
+
+<p>
+“How did you discover that?”
+</p>
+
+<p>
+“In the simplest and easiest way possible. I listed all the names you reported
+and studied them carefully, trying to find their common denominator. They were
+not in the same neighborhood, so it was not locality. They were not all German,
+so it was not racial. I looked them up in the telephone directory, checking up
+the numbers of the telephones of the Jones, the Simpsons, but that gave no
+clue. Then, as I looked through the telephone lists, I discovered that there
+was a bookstore kept by a man of each name. Then I understood. It is a simple
+plan for throwing off shadowers.”
+</p>
+
+<p>
+“You mean that Mr. Hoff goes to a different bookstore each day to leave a code
+message?”
+</p>
+
+<p>
+“That’s it. The spy who gets the messages each morning calls him up by ’phone,
+mentioning just the one word. From that Mr. Hoff knows just where to go,
+concealing the message in a book before agreed upon.”
+</p>
+
+<p>
+“The fifth book,” interrupted Dean.
+</p>
+
+<p>
+“Not always,” explained Fleck. “It depends on whether there are five letters in
+the name telephoned. I have located and copied several more of the messages.”
+</p>
+
+<p>
+“But who gets the messages he leaves? Who takes them away from the bookshops?”
+asked Jane, mindful of her own failure in that respect.
+</p>
+
+<p>
+“It’s a girl, or rather two girls together, though possibly only one of them is
+in the plot. Very likely the other may not know what her companion is doing.”
+</p>
+
+<p>
+“To whom does this girl take them?”
+</p>
+
+<p>
+“That is still a mystery,” said the chief. “We have ascertained who the girl
+is, where she lives. Her actions have been watched and recorded for every hour
+in the twenty-four for the last three days, and yet we don’t know what she does
+with these messages. Carter has a theory—tell us about it, Carter.”
+</p>
+
+<p>
+“In accordance with instructions,” began Carter, as if he was making out a
+report, “I had operatives K-24 and K-11 shadow the party suspected. On two
+different occasions they followed her to a bookstore and back home again. She
+was accompanied on one occasion by her younger sister. Each time she went
+directly home and stopped there, neither she nor her sister coming out again,
+and no person visiting the apartment, but—”
+</p>
+
+<p>
+“Here’s the interesting part,” interrupted Fleck.
+</p>
+
+<p>
+“On both occasions within a couple of blocks of the bookstore she passed a man
+with a dachshund. She did not speak to the man, but each time she stopped to
+pet the dog.”
+</p>
+
+<p>
+“Was it the same man both times?” asked Dean.
+</p>
+
+<p>
+“Apparently not,” replied Carter, “but it may have been the same dog.
+Dachshunds all look alike.”
+</p>
+
+<p>
+“Go on,” said the chief.
+</p>
+
+<p>
+“Now my theory is that that girl was instructed to walk north until she met the
+man with the dog. I’ll bet anything that code message went under the dog’s
+collar. The next time she gets a message I’m going to get that dog.”
+</p>
+
+<p>
+“It seems preposterous,” scoffed Dean.
+</p>
+
+<p>
+“Rather it shows,” said Fleck, “that these spies all suspect they are being
+watched, and that they resort to the most extraordinary methods of
+communication to throw off shadowers. They have used dachshunds before. There’s
+a New England munition plant to which they used to send a messenger each week
+to learn how their plans for strikes and destruction were progressing. They put
+a different man on the job each time to avoid stirring up suspicion. At the
+station there would always be two children playing with a dachshund. The spy
+would simply follow them as if casually, and they would lead him to a
+rendezvous with the local plotters. Now, Miss Strong,” he said, turning to
+Jane, “I brought you down here for two reasons. First, to give you an inkling
+of how important your task is, and second, to ask you to undertake still
+another task for us. Are you still willing to help?”
+</p>
+
+<p>
+“More than ever,” said the girl firmly.
+</p>
+
+<p>
+“The one disappointment is that we are getting no evidence whatever to involve
+or incriminate young Hoff. To-morrow, while he and his uncle are away on their
+usual auto trip, I am going to have the apartment thoroughly searched.”
+</p>
+
+<p>
+Jane’s face blanched. She recalled what a strain it had been on her nerves the
+day she watched on the roof while Dean installed the dictograph. She felt
+hardly equal to the task of ransacking desks and drawers.
+</p>
+
+<p>
+“There will be no one at home but the old servant. She can be easily disposed
+of. It is imperative that the search be made at once. There is evidence that
+what they are planning—evidently some big coup—is nearing the time for its
+execution. We must find it out in order to thwart them. I have got to know what
+old Hoff meant by the ‘wonder-worker!’ He said that it was nearly ready. I
+suspect that it is some new engine of destruction. We must prevent any disaster
+to transports or munition factories, if that’s what they have in mind.”
+</p>
+
+<p>
+“You think it’s a bomb plot?” asked Jane.
+</p>
+
+<p>
+“I don’t know what it is. These empire-mad fools stop at nothing. Nothing is
+sacred to them, women, children, property. With fanatical energy and ability
+they commit murders, resort to arson, use poisons, foment strikes, wreck
+buildings, blow up ships, do anything, attempt anything to serve the Kaiser.
+Karl Boy-ed spent three millions here in America in two months, and Von Papen a
+million more. What for? Ten thousand dollars to one man to start a bomb
+factory, twenty-five thousand dollars to another to blow up a tunnel. Millions
+on millions for German propaganda was raised right here, and it is far from all
+spent yet. We’ve got to find out what the wonder-worker is and destroy it
+before it destroys—God knows what.”
+</p>
+
+<p>
+“Very well,” said Jane with quiet determination, “I’ll search their apartment.”
+</p>
+
+<p>
+“No, not that,” said the chief, “I’ll send some fake inspectors to test the
+electric wiring, and they’ll do the searching. I do not know for sure that the
+Hoffs suspect you of watching them, but I’m taking no chances. It will be just
+as well for you and Dean to be out of the way to-morrow all day, so that you
+will have an alibi. Germany’s secret agents are suspicious of everybody. They
+do not even trust their own people. What I want you and Dean to do is to try to
+follow the Hoffs and see where they go. I don’t want to use the same persons
+twice to trail them as they may get suspicious.”
+</p>
+
+<p>
+“I can easily do that,” said Jane, feeling relieved. “I’ll tell Mother I want
+our car for all day.”
+</p>
+
+<p>
+“No, don’t use your own car. They might recognize it. I’ll provide another one.
+They gave two of my men the slip last week somewhere the other side of
+Tarrytown. Let’s hope they are not so successful this time.”
+</p>
+
+<p>
+“But won’t they recognize me?”
+</p>
+
+<p>
+“Not if you disguise yourself with goggles and a dust coat. Dean can make up,
+too. He had practice enough at college, eh, Dean?”
+</p>
+
+<p>
+Jane turned to look interestedly at Dean, who had the grace to color up. She
+was right then. He was a college man, working in the secret service not for the
+sake of the job but for the sake of his country.
+</p>
+
+<p>
+“Of course I can disguise myself too,” she said enthusiastically, a new zest in
+her work asserting itself, now that she knew her principal co-operator was
+probably in the same social stratum as herself.
+</p>
+
+<p>
+“You can rely on us, Chief,” said Dean, as they left the office together.
+“We’ll run them down.”
+</p>
+
+<p>
+As they emerged into Broadway and turned north to reach the subway at Fulton
+Street, Dean, with a warning “sst,” suddenly caught Jane’s arm and drew her to
+a shop window, where he appeared to be pointing out some goods displayed there.
+As he did so he whispered:
+</p>
+
+<p>
+“Don’t say a word and don’t turn around, but watch the people passing, in this
+mirror here—quick, now, look.”
+</p>
+
+<p>
+Jane, as she was bidden, glanced, at first curiously and then in recognition
+and amazement, at a tall figure reflected in the mirror, as he passed close
+behind her. It was a man in uniform. Regardless of Dean’s warning she turned
+abruptly to stare uncertainly at the military back now a few paces away.
+</p>
+
+<p>
+“Did you recognize him?” cried Dean.
+</p>
+
+<p>
+“It—it looked like Frederic Hoff,” faltered the girl.
+</p>
+
+<p>
+“It was Frederic Hoff,” corrected her companion, “Frederic Hoff in the uniform
+of a British officer, a British cavalry captain!”

+<h2><a name="CHAPTER_IX"></a>CHAPTER IX<br/>
+THE PURSUIT</h2>
+
+<p>
+Masked by an enormous pair of motor goggles and further shielded from
+recognition by a cap drawn down almost over his nose, Thomas Dean in a
+basket-rigged motorcycle impatiently sat awaiting the arrival of Jane Strong at
+a corner they had agreed upon the evening before. He had been particularly
+insistent that Jane should be on hand at a quarter before eight. He had learned
+by judicious inquiries that always on Wednesdays—at least on the Wednesdays
+previous—the Hoffs had started off on their mysterious trips at eight sharp.
+His intention was to get away ahead of them and pick them up somewhere outside
+the city limits.
+</p>
+
+<p>
+Jane had promised that she would be on hand promptly. Once more he looked
+impatiently at his watch. It lacked just half a minute of the quarter, but
+there was no sign of his fellow operative. The only person visible in the block
+was a boy strolling carelessly in his direction. With a muttered exclamation of
+annoyance Dean restored his watch to his pocket, debating with himself how long
+he ought to wait and whether or not he had better wait if she did not appear
+soon. Very possibly, he realized, something entirely unforeseen might have
+detained her or have prevented her coming. Perhaps her family had doubted her
+story that she was going off on an all-day motor trip with a friend? Maybe
+their suspicions had been aroused by his having reported sick? He had almost
+decided to go on alone when he observed that the boy he had seen approaching
+was standing beside the motorcycle.
+</p>
+
+<p>
+“Good morning, Thomas,” said the boy, a little doubtfully, as if not quite sure
+that it was he.
+</p>
+
+<p>
+Dean gasped in astonishment. The boy’s voice was the voice of Jane. Laughing
+merrily at his amazement and discomfiture, she climbed into the seat beside
+him, asking:
+</p>
+
+<p>
+“How do you like my disguise?”
+</p>
+
+<p>
+“It’s great,” he cried. “You fooled me completely, and I was expecting you.”
+</p>
+
+<p>
+“When Chief Fleck said I ought to disguise myself for fear that the Hoffs
+already suspected me, I happened to remember these clothes. I had them once for
+a play we gave in school.”
+</p>
+
+<p>
+“But you don’t even walk like a girl.”
+</p>
+
+<p>
+Jane laughed again.
+</p>
+
+<p>
+“I practised that walk for days and days. When I first put on this suit my
+brother hooted at the way I walked. He said no girl ever could learn to walk
+like a boy. I made up my mind I’d show him.”
+</p>
+
+<p>
+“But your hair,” protested Dean, almost anxiously. Even if he was just now
+assuming the humble r&ocirc;le of chauffeur he still was an ardent admirer of
+such hair as Jane’s, long, black and luxurious.
+</p>
+
+<p>
+“Tucked up under my cap,” laughed the girl, “and for fear it might tumble down,
+I brought this along. It’s what the sailor boys call a ‘beanie,’ isn’t it?”
+</p>
+
+<p>
+As she spoke she adjusted over her head a visorlike woolen cap that left only
+her face showing.
+</p>
+
+<p>
+“But your mother—didn’t she wonder about your wearing those clothes?”
+</p>
+
+<p>
+“She was in bed when I left. All she caught was just a glimpse of me in Dad’s
+dust coat, and that came to my ankles. I wore it until I was a block away from
+the house. Will I do?”
+</p>
+
+<p>
+“You can’t change your eyes,” said Dean boldly, that is boldly for a chauffeur,
+but he knew that Jane knew he wasn’t a chauffeur except by choice, so that made
+it all right.
+</p>
+
+<p>
+“I couldn’t well leave them behind. I understood that I was to have a lot of
+use for my eyes to-day.”
+</p>
+
+<p>
+“Yes, indeed, you very likely will.”
+</p>
+
+<p>
+“Do you know I hardly recognized you at first and was almost afraid to speak? I
+had expected to find you in a car. What was the idea of the motorcycle?”
+</p>
+
+<p>
+“It was Chief Fleck’s suggestion. The Hoffs will be motoring. People in a car
+seldom pay any attention to motorcyclists. If we were to follow them in a motor
+they’d surely notice it. Last week they managed to dodge the people the Chief
+assigned to trail them. Maybe as two dusty motorcyclists we’ll have better
+luck.”
+</p>
+
+<p>
+“I hope so. Where do you intend waiting to pick them up?”
+</p>
+
+<p>
+“Getty Square in Yonkers is the best place. Everybody going north goes that
+way. I can be tinkering with the machine while you keep watch for them. They
+will not be apt to suspect a pair of Yonkers motorcyclists. There’s no danger
+of missing them.”
+</p>
+
+<p>
+“Did you tell the Chief about seeing Mr. Hoff in that uniform?”
+</p>
+
+<p>
+“Of course. He did not seem even surprised. Some one had reported to him
+already that there was a German going about in British uniform.”
+</p>
+
+<p>
+“What had he heard? What was the man doing?” questioned Jane anxiously. Even
+though she believed Frederic Hoff an alien enemy, even though she was all but
+sure that he was a murderer, she kept finding herself always hoping for
+something in his favor. He seemed far too nice and entertaining to be engaged
+in any nefarious, underhanded, despicable machinations. Yet she had seen him
+masquerading as a British officer. She could not doubt the evidence of her own
+eyes.
+</p>
+
+<p>
+“What happened was this,” continued Dean. “A woman—one of the society lot—was
+driving down Park Avenue day before yesterday morning in her motor. It had been
+raining, and the streets were muddy. At one of the crossings a British officer
+stopped to let the car pass. One of the wheels hit a rut, and his uniform was
+all splashed with mud. He burst into a string of curses—<i>German</i> curses.”
+</p>
+
+<p>
+“He cursed in German?” cried Jane.
+</p>
+
+<p>
+“Sure,” said Dean. “On the impulse of the moment he forgot his r&ocirc;le and
+revealed his true self—an arrogant Prussian officer.”
+</p>
+
+<p>
+“What did the woman do?”
+</p>
+
+<p>
+“Reported him to the first policeman she met, but by that time he had vanished,
+of course.”
+</p>
+
+<p>
+“What did Chief Fleck think about it?”
+</p>
+
+<p>
+“He didn’t seem to take the story seriously.”
+</p>
+
+<p>
+“Do you suppose it could have been Mr. Hoff?”
+</p>
+
+<p>
+“It must have been he, or one of his gang, at any rate. I don’t see why the
+Chief does not order his arrest at once. He is far too dangerous to be at
+large.”
+</p>
+
+<p>
+“There’s no real evidence against him yet,” protested Jane, “not against the
+young man, at least.”
+</p>
+
+<p>
+“Didn’t we both see him in British uniform?”
+</p>
+
+<p>
+“Yes,” admitted the girl.
+</p>
+
+<p>
+“Well, that’s proof, isn’t it? A man with a German name in British uniform in
+wartime can’t be up to any good.”
+</p>
+
+<p>
+“Still we have no actual evidence against him. We don’t know what he was
+doing.”
+</p>
+
+<p>
+“I’d arrest him then for murder and get the evidence that he is a spy
+afterward. It would be easy to fasten the murder of K-19 on him. There’s no
+doubt that he did that.”
+</p>
+
+<p>
+“Has a witness been found?” asked Jane with a quick catch of the breath.
+Somehow she never had been able to persuade herself that the man next door,
+whatever else he might be, had really committed that brutal murder.
+</p>
+
+<p>
+“No, there’s no actual witness, but it could be proved by circumstantial
+evidence. K-19, the man whose work you took up, had instructions to shadow
+young Hoff to his home. At two in the morning he relieved another operative. At
+three you yourself saw him shadowing Hoff.”
+</p>
+
+<p>
+“I saw two men on the sidewalk,” corrected Jane. “One of them was Frederic
+Hoff. I did not see the other distinctly enough to identify him. I saw no
+murder. I merely saw the two of them run around the corner.”
+</p>
+
+<p>
+“Look here,” said Dean sharply, not wholly succeeding in suppressing a note of
+jealousy in his tones, “I believe you are trying to shield Frederic Hoff. What
+is he to you? Has he won you over to his side?”
+</p>
+
+<p>
+“You’ve no right to say such things to me,” cried Jane, nevertheless coloring
+furiously. “I’ve seen the man only three or four times. I am working just as
+hard as you are to prove that he is a German spy, if he is one. I am only
+trying to be fair. I know nothing that convicts him of murder. Any testimony I
+could give would not prove a single thing.”
+</p>
+
+<p>
+“Certainly not, if that’s the way you feel about it,” snapped Dean.
+</p>
+
+<p>
+After that they rode along together in silence, each busy with thoughts of
+their own. Dean was cursing himself for having let his enthusiasm to be of
+service to his government lead him into such circumstances. He felt that his
+chauffeur’s position handicapped him in his relations with Jane, to whom he had
+been strongly attracted from the beginning. The son of a distinguished American
+diplomat, he had been educated for the most part in Europe. Friends of his
+father, when he had offered his services to the government, had convinced him
+that his knowledge of German and French would make him most useful in the
+secret service. Reluctantly he had consented to take up the work, and as he had
+gone further and further into it and had realized the vast machinery for
+surreptitious observation and dangerous activity that the German agents had
+secretly planted in the United States, he had become fascinated with his
+occupation—that is, until he met Jane Strong.
+</p>
+
+<p>
+His association with her under present circumstances was fast becoming
+unbearable. Even though he was aware that she knew he was no ordinary
+chauffeur, he loathed the necessity of having to wear his mask in the presence
+of her family. He wanted to be free to come to see her, to send her flowers and
+to go about with her. For him to take any advantage of their present intimate
+relations to court her seemed to him little short of a betrayal of his
+government, yet at times it was all he could do to keep from telling her that
+he adored her. Love’s sharp instincts, too, had made him realize that Jane was
+already beginning to be attracted by the handsome young German whom they were
+seeking to entrap, and the knowledge of this fact filled him with helpless rage
+and jealousy.
+</p>
+
+<p>
+Jane, too, angered and insulted at first by Dean’s outburst, had been
+endeavoring to analyze her own conduct. Candor reluctantly compelled her to
+admit that each time she met Frederic Hoff she had found herself coming more
+and more under his spell. He had a wonderful personality, talked entertainingly
+and ever exhibited an innate gallantry toward women in general, and herself in
+particular, which Jane had found delightfully interesting. Though she had
+undertaken wholeheartedly to try to get evidence against him, she was forced to
+admit to herself now that she was secretly delighted that there had been
+nothing damaging found as yet, so far as he was concerned, beyond the one fact
+that he had been in British uniform.
+</p>
+
+<p>
+In vain she marshalled the circumstances about him, trying to make herself hate
+him. He was a German, she told herself. He was an enemy of her country. He
+lived with a man who had been proved to be a spy. He surreptitiously associated
+with American naval officers. The dictograph told her that nightly his uncle
+and he in the seclusion of their home toasted America’s arch enemy, the German
+Kaiser. More than likely, too, her reason told her, he was a murderer. She
+ought to hate, to loathe, to despise him, and yet she didn’t. She liked him.
+Whenever he approached she could feel her heart beating faster. She looked
+forward after each meeting with him to the time when she would see him again.
+What, she wondered, could be the matter with her? Assuredly she was a good
+patriotic American girl. Why couldn’t she hate Frederic Hoff as she knew he
+ought to be hated?
+</p>
+
+<p>
+She was still puzzling over her unruly heart when they reached Getty Square,
+and Dean brought the motorcycle to a stop in one of the side streets
+overlooking Broadway. Dismounting, he looked at his watch and made a pretense
+of tinkering with the engine, while Jane kept a sharp lookout on the main
+thoroughfare, by which they expected the Hoffs to approach. Ten minutes, twenty
+minutes, more than half an hour they waited, anxiously scanning each car as it
+passed.
+</p>
+
+<p>
+“I can’t understand it,” said Dean. “They should have been here at least twenty
+minutes ago. I am going to ’phone Carter. He will know what time they started.”
+</p>
+
+<p>
+He had hardly entered an adjacent shop before Jane, still keeping watch, saw
+the Hoffs’ car flash by, going rapidly north. Quickly she sprang out and ran
+into the store. Dean saw her coming and left the telephone booth, his finger on
+his lips in a warning gesture.
+</p>
+
+<p>
+“Don’t bother to ’phone,” cried the girl, misunderstanding his meaning—and
+thinking only that he was trying to prevent her naming the Hoffs. “Come, let’s
+get started.”
+</p>
+
+<p>
+Without speaking he hurried from the store and got the motorcycle under way.
+</p>
+
+<p>
+“Have they passed?” he whispered then.
+</p>
+
+<p>
+“Just a moment ago.”
+</p>
+
+<p>
+Silently he gathered up speed, racing in the direction the Hoffs’ car had gone,
+not addressing her again until perhaps two miles from Getty Square they caught
+up with it close enough to identify the occupants, whereupon he slowed down and
+followed at a more discreet interval.
+</p>
+
+<p>
+“Be careful about speaking to me when there’s any one about,” he warned Jane,
+almost crossly. “Those clothes make you look like a boy, and your walk is all
+right, but your voice gives you away. Did you see that clerk in the store look
+at you when you spoke to me? I tried to warn you to say nothing.”
+</p>
+
+<p>
+“I’ll be careful hereafter,” said Jane humbly, still depressed by her recent
+estimate of herself. “I forgot about my voice.”
+</p>
+
+<p>
+Mile after mile they kept up the pursuit without further exchange of
+conversation. As they passed through various towns along the road Dean
+purposely lagged behind for fear of attracting attention, but always on the
+outskirts he raced until he caught up close enough again to the car to identify
+it, then let his motorcycle lag back again. Thus far the Hoffs had given no
+indication of any intention to leave the main road.
+</p>
+
+<p>
+As the cyclists, far behind, came down a long winding hill on which they had
+managed to catch occasional glimpses of their quarry, Dean, with a muttered
+exclamation, put on a sudden burst of speed. At a rise in the road he had seen
+the Hoffs’ car swing sharply to the left. Furiously he negotiated the rest of
+the hill, arriving at the base just in time to see them boarding a little ferry
+the other side of the railroad tracks. While he and Jane were still five
+hundred yards away the ferryboat, with a warning toot, slipped slowly out into
+the Hudson.
+</p>
+
+<p>
+In blank despair they turned to face each other. The situation seemed hopeless.
+They dared not shout or try to detain the boat. That surely would betray to the
+Hoffs that they were being followed. Despondently Dean clambered off the
+motorcycle and crossed to read a placard on the ferryhouse.
+</p>
+
+<p>
+“There’s not another boat for half an hour,” he said when he returned. “They
+have gained that much on us.”
+</p>
+
+<p>
+“Perhaps we can pick up their trail on the other side of the river,” suggested
+Jane. “There are not nearly so many cars passing as there would be in the
+city.”
+</p>
+
+<p>
+“We can only try,” said Dean gloomily.
+</p>
+
+<p>
+“At least we know where to pick up their trail the next time.”
+</p>
+
+<p>
+“Damn them,” cried Dean, “I believe they suspect that they may be followed and
+time their arrival here so as to be the last aboard the ferryboat. That shuts
+off pursuit effectually. They make this trip every week. I wouldn’t be
+surprised if they have not fixed it with the ferry people to pull out as soon
+as they arrive. A two-dollar bill might do the trick. I’d give five thousand
+right now if we were on the other side of the river. It’s the first time—the
+only time I’ve ever failed the Chief.”
+</p>
+
+<p>
+“Never mind,” said Jane consolingly, “why can’t we be waiting for them at the
+other side next week when they come up here? They’re not apt to suspect
+motorcyclists they meet up here with having followed them.”
+</p>
+
+<p>
+“Perhaps next week will be too late.”
+</p>
+
+<p>
+“I wonder where they are headed for,” said the girl, looking across at the
+rapidly receding boat. “Why, look! What are those buildings over there?”
+</p>
+
+<p>
+“That’s West Point,” Dean exclaimed, noting for the first time where they were.
+</p>
+
+<p>
+“West Point!” she echoed in amazement.
+</p>
+
+<p>
+What mission could the Hoffs have that would take them to the United States
+Government military school was the question that perplexed them both. Could it
+be that the web of treachery and destruction the Kaiser’s busy agents were
+weaving had its deadly strands fastened even here—at West Point?

+CARTER’S DISCOVERY</h2>
+
+<p>
+“It’s the young man I’m after,” said Chief Fleck. “We have the goods on old
+Hoff, but we have nothing incriminating against Frederic yet. The very fact
+that he holds aloof from his uncle’s activities makes me think he is engaged in
+more important work. He’s just the type the Germans would select as a
+director.”
+</p>
+
+<p>
+“That’s right,” said Carter despondently. “There’s nothing except the fact that
+Dean and the girl think they saw him in British uniform. Why didn’t they follow
+and make sure?”
+</p>
+
+<p>
+“They tried to,” said the chief, “but he gave them the slip. I’m inclined to
+believe they were mistaken. More than likely it was a chance resemblance. Lots
+of Britishers of the Anglo-Saxon strain look much like Germans, and a uniform
+makes a big difference in a man’s appearance. I’m afraid there’s nothing in
+that.”
+</p>
+
+<p>
+“But both saw the man—Dean and Miss Strong,” protested Carter.
+</p>
+
+<p>
+“The trouble is,” observed Fleck, “that Dean is getting infatuated with the
+girl. A young man in love is not a keen observer. Anything she thinks she has
+seen he’ll be ready to swear to. I hope the girl keeps her head. Lovers don’t
+make good detectives.”
+</p>
+
+<p>
+“I have watched them together,” said Carter. “I’ll admit he’s struck on her,
+but I don’t think she cares a rap for him. She’s too keenly interested in
+Frederic Hoff.”
+</p>
+
+<p>
+“What do you mean by that?” asked the chief sharply.
+</p>
+
+<p>
+“You can depend on her all right. She’s patriotic through and through. She’s
+the kind that would do her duty, no matter what it cost her. All I meant is
+that Hoff’s the type that interests women. He’s got a way about him. The fact
+that he’s a spy, in peril most of the time, gives him a sort of halo. I never
+knew a daring young criminal yet that didn’t have some woman, and often several
+of them, ready to go the limit for him. All the same, I’m sure we can trust
+Miss Strong.”
+</p>
+
+<p>
+“We’ve got to,” growled Fleck, “for the present at any rate. Is everything
+fixed for the search this afternoon? What have you done to get the
+superintendent out of the way? He’s not to be trusted. His name is Hauser.”
+</p>
+
+<p>
+“I’ve got him fixed. Jimmy Golden, my nephew, who has helped us in a couple of
+cases, is a lawyer. He has telephoned to Hauser to come to his office this
+afternoon.”
+</p>
+
+<p>
+“Suppose he doesn’t go?”
+</p>
+
+<p>
+“He’ll go all right. Jimmy ’phoned him that it was about a legacy. That’s sure
+bait. Jimmy will make Hauser wait an hour, then keep him talking half an hour
+longer. That will give us plenty of time.”
+</p>
+
+<p>
+“Then there’s the woman—the servant, Lena Kraus.”
+</p>
+
+<p>
+“She goes to the roof every Wednesday while the Hoffs are away to signal. Other
+days they apparently do the signalling themselves in some way we haven’t caught
+on to yet. She always goes up about three o’clock and—”
+</p>
+
+<p>
+“Suppose she comes down unexpectedly and catches you? We can’t have that
+happen. That would put them on their guard.”
+</p>
+
+<p>
+“She won’t surprise us. I’ve got a trick up my sleeve for preventing that.”
+</p>
+
+<p>
+“Go to it, then,” said the chief, and Carter went on his way rejoicing.
+</p>
+
+<p>
+Ever since he had been informed that the search of the Hoffs’ apartment was to
+be intrusted to him Carter had been in a state of exuberant delight. He fairly
+revelled in jobs that required a disguise and he welcomed the opportunity it
+gave him and his assistants to don the uniform of employees of the electric
+light company. He even made a point of arriving that afternoon at the apartment
+house in the company’s repair wagon, the vehicle having been procured through
+Fleck’s assistance.
+</p>
+
+<p>
+“There’s a dangerous short circuit somewhere in the house,” he announced to the
+superintendent’s wife.
+</p>
+
+<p>
+“My husband isn’t here,” she answered unsuspectingly. “Do you know where the
+switch-boards are?”
+</p>
+
+<p>
+“We can find them,” said Carter. “We’ll start at the top floor and work down.”
+</p>
+
+<p>
+Always thorough in his methods of camouflage he actually did go through several
+apartments, making a pretense of inspecting switch-boards and wiring, all the
+while keeping watch for the time when old Lena went to the roof. The moment she
+had entered the elevator to ascend with her basket of linen, Carter and his
+aides were at the Hoff door. Equipped with the key Dean had manufactured they
+had no difficulty in entering.
+</p>
+
+<p>
+“Bob,” said Carter to one of his men, “we haven’t much time, and there’s a lot
+to be done. You take the servant’s room and the kitchen, and you, Williams,
+take the old man’s quarters. I’ll take care of the young man’s bedroom, and
+we’ll tackle the living room and dining room later.”
+</p>
+
+<p>
+Thoroughly experienced in this sort of work all three of them set at once to
+their tasks. Carter, standing for a moment in the doorway, surveyed Frederic
+Hoff’s quarters, taking in all the details of the furnishings. Both the sitting
+room and the bedroom adjoining were equipped in military simplicity, with
+hardly an extra article of furniture or adornment, chairs, tables, everything
+of the plainest sort. Moving first into the bedroom, Carter quickly
+investigated pillows and mattress, but in neither place did he find what he
+sought, evidence of a secret hiding place. He rummaged for a while through the
+drawers of two tables, carefully restoring the contents, but discovering
+nothing that aroused his suspicions. The books lying about on the tables and on
+shelves he examined one by one, noting their titles, examining their bindings
+for hidden pockets, holding them up by their backs and shaking the leaves.
+There was nothing there. Lifting the rugs and moving the furniture about he
+made a careful survey of the flooring, seeking to find some panel that might
+conceal a hiding place. Once or twice in corners he went so far as to make
+soundings but apparently the whole floor was intact. His search in the bath
+room was equally profitless, and at last he turned to the clothes press. As he
+opened the door an exclamation of amazement burst from his lips.
+</p>
+
+<p>
+There, concealed behind some other suits, was the complete outfit of a British
+cavalry captain.
+</p>
+
+<p>
+“That’s one on the Chief,” he said to himself. “It must have been Hoff that
+Dean and Miss Strong saw. I wonder where he got it?”
+</p>
+
+<p>
+With a grim smile of satisfaction he devoted himself to going carefully through
+all the pockets and over all the seams of the clothing in the closet. He even
+felt into the toe of the shoes and examined the soles. There was nothing to be
+found anywhere, but he felt satisfied. The uniform in itself was to his mind
+damning proof of the young man’s occupation.
+</p>
+
+<p>
+No explanation that could be given by a young man of German name, even though
+he was American-born, or had an American birth certificate, could possibly
+account for his having a British uniform. It was prima facie evidence that
+Frederic Hoff was a spy. What puzzled Carter most was how Hoff managed to
+smuggle the uniform in and out of the apartment without being observed. For
+more than two weeks now every parcel that had arrived at the house of the Hoffs
+had been searched before it was delivered. The house had been constantly under
+the strictest surveillance. It was out of the question for him to have worn the
+uniform in or out as it could not be easily concealed under other clothing.
+</p>
+
+<p>
+“There’s somebody else in this place in league with the Hoffs,” he muttered to
+himself. “I wonder who it can be.”
+</p>
+
+<p>
+He looked at his watch. The old servant had been out now nearly half an hour.
+She was likely to return at any moment. He must work quickly. Swiftly he went
+through the dresser drawers but without satisfactory result. There was no time
+for him to do more. He hastened into the living room and summoned his aides.
+</p>
+
+<p>
+“Find anything, Bob?” he asked.
+</p>
+
+<p>
+“Not a thing.”
+</p>
+
+<p>
+“Beat it up to the roof,” he directed. “Have you those field glasses with you?”
+</p>
+
+<p>
+“Sure,” replied the operative, “and the handkerchiefs, too.”
+</p>
+
+<p>
+“All right. Get up there before she starts down. Begin putting up handkerchiefs
+and appear to be watching the river. That will mix her up so she will not know
+what to do. She will not dare to leave the roof while you are there. When we’re
+through I’ll send the elevator man up for you with the message that we have
+found the short circuit.”
+</p>
+
+<p>
+He turned to the other operative.
+</p>
+
+<p>
+“Find anything, Williams?”
+</p>
+
+<p>
+“Only this.”
+</p>
+
+<p>
+Carter’s face brightened as his assistant held out to him two copies of an
+afternoon newspaper. In each of them a square was missing where something had
+been cut out.
+</p>
+
+<p>
+“I found them in the waste-paper basket by the old man’s desk,” the man
+explained, “and there was some ashes there—ashes of paper—as if he had burned
+up something. Maybe it was what he cut out of those papers. I could not tell.”
+</p>
+
+<p>
+“We’ve got to get copies of those papers at once and see what it was. Come on,
+I’m going to take them to the Chief. We can get the papers on the way down.”
+</p>
+
+<p>
+Calling the other operative from the roof, before he even had had time to
+attract the attention of Lena Kraus by his activities, they hastened back to
+the office, where Fleck and Carter together scanned the two papers from which
+the clippings had been taken.
+</p>
+
+<p>
+“Why,” said Carter disappointedly, “it is just a couple of advertisements he
+cut out—advertisements for a tooth paste. There’s nothing in that.”
+</p>
+
+<p>
+“Don’t be too sure,” warned Fleck. “If a man cuts out one tooth-paste
+advertisement, the natural presumption would be that he wished to remind
+himself to buy some. When he cuts out two, he must have some special interest
+in that particular tooth paste. We’ll have to find out what his interest is.”
+</p>
+
+<p>
+“Maybe he owns it,” suggested Carter.
+</p>
+
+<p>
+“Perhaps,” said Fleck, as he began studying the advertisements, “but it would
+not surprise me if these advertisements contained some sort of code messages.”
+</p>
+
+<p>
+“Messages in advertisements,” exclaimed Carter incredulously.
+</p>
+
+<p>
+“Why not? The Germans have hundreds of spies at work here in this city and all
+over the country. What would be an easier method of communicating orders to
+them than by code messages concealed in advertising. They have done it before.
+When the German armies got into France they found their way placarded in
+advance with much useful information in harmless looking posters advertising a
+certain brand of chocolate. I’d be willing to bet that every one of these
+advertisements carries a code message. I’ve noticed that these advertisements,
+all peculiarly worded, have been running for some time. I never thought of
+hooking them up with German propaganda, but, see, it is a German firm that
+inserts them.”
+</p>
+
+<p>
+Carefully he cut out the two advertisements and laid them side by side on his
+desk. Turning to Carter he said:
+</p>
+
+<p>
+“Go at once to see Mr. Sprague, the publisher of this paper. Get him to give
+you a copy of each paper that has contained an advertisement of this sort in
+the last six months. Find out what agency places the advertising. Tell him I
+want to know. He’ll understand. We have worked together before.”
+</p>
+
+<p>
+Alone in his office, Fleck bent with wrinkled brow over the first of the two
+advertisements, which read:
+</p>
+
+<p class="center">
+REMEMBER
+</p>
+
+<p class="letter">
+Please, that our new paste, DENTO,<br/>
+will stop decay of your teeth. Sound<br/>
+teeth are passports to good health and<br/>
+comfort. Now, no business man can<br/>
+risk ill health. It is closely allied with<br/>
+failure. The teeth if not watched are<br/>
+quickly gone.
+</p>
+
+<p class="center">
+USE DENTO
+</p>
+
+<p class="letter">
+A genuine, safe, pleasing paste for the<br/>
+teeth, prepared and sold only by the<br/>
+Auer Dental Company, New York.
+</p>
+
+<p>
+He tried all the methods of solving cipher letters that he thought of. He drew
+diagonals this way and that across the advertisement. He tried reading it
+backward. He tried reading every other word, every third word, both backward
+and forward. Nothing that he did revealed any combination of words that made
+sense.
+</p>
+
+<p>
+“Passports,” he muttered to himself, “that’s it. If there is a message there it
+must be something about passports.”
+</p>
+
+<p>
+In despair he turned to the other advertisement. It read:
+</p>
+
+<p class="center">
+DON’T
+</p>
+
+<p class="letter">
+Forget it is imperative for one and all to<br/>
+use cleansing agents on teeth that leave<br/>

+“Ship more of that wonder-working<br/>
+paste immediately. Workers, employers,<br/>
+wives, all ready to commend it. Friday’s<br/>
+supply gone,” writes a druggist to whom<br/>
+a big shipment was made last week.

+
+<p class="center">

+</p>
+
+<p class="letter">
+A genuine, safe, pleasing paste for the<br/>
+teeth, prepared and sold only by the<br/>
+Auer Dental Company, New York.
+</p>
+
+<p>
+Fleck’s eyes gleamed with satisfaction as he read this advertisement and caught
+the phrase “wonder-working.” He felt sure now that he was on the right track.
+He recalled that Jane Strong over the dictograph had heard old Hoff speak of
+something that he called the “wonder-worker.” As soon as Carter returned with
+the other advertisements that had been appearing he felt positive that he would
+be able to unravel the cipher. Two words he was sure of—“passports” and
+“wonder-working.” One footprint does not lead anywhere, but two do, and given
+three footprints, a pathway is indicated.
+</p>
+
+<p>
+His telephone rang sharply. He turned to answer it, suspecting it must be
+Carter with some message about the papers he had sent for.
+</p>
+
+<p>
+“Hello,” he called.
+</p>
+
+<p>
+“Hello,” came a faint voice, as if the speaker were using long distance, and
+had a bad connection, “is this Fleck?”
+</p>
+
+<p>
+“Yes, Fleck,” he answered, “who is this?”
+</p>
+
+<p>
+“Dean speaking,” came the voice faintly.
+</p>
+
+<p>
+“Dean,” cried Fleck, excitedly, “yes, yes. What is it, Dean?”
+</p>
+
+<p>
+He had not expected to hear any results from the expedition that Dean and Jane
+Strong had undertaken until late in the afternoon after the Hoffs returned. The
+fact that Dean was calling him up now would seem to indicate that something of
+importance had happened.
+</p>
+
+<p>
+“I’m telephoning from a doctor’s house near Nyack,” said Dean.
+</p>
+
+<p>
+“What’s that? Speak louder.”
+</p>
+
+<p>
+“I’m here in Doctor Spencer’s office near Nyack with a broken arm,” Dean
+continued. “We’ve had an accident. Somebody’s auto smashed into us, I guess.”
+</p>
+
+<p>
+“Miss Strong? Where is she? Is she hurt?” asked the chief anxiously.
+</p>
+
+<p>
+“I don’t know. She has vanished.”
+</p>
+
+<p>
+Jane Strong vanished! The chief’s figure became suddenly tensed. That it was
+more than a mere automobile accident he felt certain now. Shadowing the Hoffs
+was an occupation that seemed unusually perilous. There flashed into his mind
+the fate of K-19—murdered almost at the Hoffs’ door. And now two more of his
+operatives, one disabled and the other mysteriously missing.
+</p>
+
+<p>
+“Quick,” he said over the ’phone. “Tell me briefly just what happened. Speak as
+loudly as you can.”
+</p>
+
+<p>
+“We got half an hour behind at the West Point Ferry,” Dean’s voice went on,
+still weak and low as if he were speaking with difficulty. “We had some trouble
+getting started on the trail again but finally succeeded. We were dashing along
+about ten or twelve miles south of West Point when an automobile coming out of
+a cross road crashed right into us. It must have knocked me unconscious. I
+didn’t remember anything more till I found myself here. I came to as the doctor
+was setting my arm. I ’phoned as soon as they would let me.”
+</p>
+
+<p>
+“Who brought you there?”
+</p>
+
+<p>
+“I don’t know. All they know here was that some couple in an automobile left me
+here. They said they passed just after an auto hit my motorcycle. They said the
+auto didn’t stop.”
+</p>
+
+<p>
+“And Miss Strong—did they say anything about her?”
+</p>
+
+<p>
+“Not a word. The people here were under the impression I was riding alone.”
+</p>
+
+<p>
+“All right,” said the chief. “I’ll get some one up there at once to look after
+you and pick up any clues.”
+</p>
+
+<p>
+As he hung up the ’phone, his forehead wrinkled into little lines of absorbed
+concentration. He sat at his desk for fully five minutes almost motionless,
+trying to figure it out. What did the accident to Dean signify? How was the
+sudden disappearance of Jane Strong to be accounted for? Had she fled from the
+scene after Dean was disabled, fearing that her name might be coupled with his
+in an account of the accident? It did not seem like the sort of thing she would
+do. The impression she had made on him was that of a girl of high resolve who
+would be apt to carry through anything she undertook, cost what it may. Yet
+what could have happened to her? If she, too, had been injured, why was she not
+with Dean? If she was not injured, why had she not communicated with the
+office? Who were the couple that had brought Dean to the doctor’s office? Why
+had not the doctor taken their names and addresses?
+</p>
+
+<p>
+What part had the Hoffs played in the accident? Had they purposely run down the
+motorcycle? If they had found out they were being shadowed they would not have
+hesitated, he felt sure, to resort to such murderous tactics. Had they not
+already one dastardly murder to their record? He must find out when the Hoffs
+arrived home. They would not be due for an hour or two, but he would caution
+the operatives watching the house to keep more vigilant watch. Reaching for his
+’phone he called up the head-quarters of the operatives.
+</p>
+
+<p>
+“Report to me at once,” he said to the operative who answered his call, “the
+minute the Hoffs have arrived home.”
+</p>
+
+<p>
+“The old man is home now,” the operative answered.
+</p>
+
+<p>
+“What’s that?” cried Fleck.
+</p>
+
+<p>
+“He came in alone five minutes ago on foot. The young man is not home yet with
+the automobile.”
+</p>
+
+<p>
+“Let me know as soon as he arrives,” said Fleck curtly, turning away from the
+’phone.
+</p>
+
+<p>
+He was more perplexed than ever. What could have happened? Where was young Hoff
+with the motor? Where was Jane Strong? Why had she disappeared after Dean had
+been hurt? How had she vanished? The Hoffs’ affairs had assuredly taken a new
+and bothersome turn, over which Fleck sat puzzling many minutes.
+</p>
+
+<p>
+Where was Jane Strong? In the answer to that question, he decided at length,
+lay the crux of the whole situation.

+<h2><a name="CHAPTER_XI"></a>CHAPTER XI<br/>
+JANE’S ADVENTURE</h2>
+
+<p>
+For more than two hours Thomas Dean and Jane had been vainly circling about
+West Point on their motorcycle, striving to pick up some clue that would put
+them once more on the trail of the Hoffs’ car. They had not dared to ask too
+many questions of any one near the ferry, fearful lest the people they were
+pursuing might have a guard posted there to warn them in case of a possible
+pursuit, yet cautious inquiries seemed to indicate that all the automobiles on
+the ferryboat which had preceded had been headed to the north.
+</p>
+
+<p>
+“There’s only one thing we can do,” Dean had said despondently. “We have got to
+run out each road we come to until we reach some shop or garage where the
+people would be likely to have noticed the Hoffs. They may have stopped
+somewhere, or we may meet some one coming toward us who will remember having
+passed them.”
+</p>
+
+<p>
+“It seems like a wild-goose chase,” said Jane, “but I suppose there is nothing
+else to do.”
+</p>
+
+<p>
+The strain of their bitter disappointment was telling on both of them. Each
+felt inclined to blame the other for their having fallen so far behind. They
+rode along in silence, their nerves becoming more and more keyed up as their
+hopes grew less. At garage after garage they paused to question the employees.
+</p>
+
+<p>
+“Did a big gray car with two men, an old man with a beard and a young man
+driving, pass this way about an hour ago?”
+</p>
+
+<p>
+“I don’t remember any such car,” was the invariable answer.
+</p>
+
+<p>
+Time and time again they repeated their query, wording it always the same,
+except for lengthening the interval of time in which the car might have passed,
+for the afternoon was rapidly passing. In their circuit they had now reached
+the roads pointing to the southward.
+</p>
+
+<p>
+“We’ll try this one more garage,” said Dean, as they approached a wayside shed
+bearing a large sign “Gasoline.”
+</p>
+
+<p>
+“I fear it is only wasting time,” said Jane wearily.
+</p>
+
+<p>
+“Don’t you want the Hoffs caught?” snapped her companion.
+</p>
+
+<p>
+“Of course I do,” she retorted heatedly, “but I don’t see you catching them.”
+</p>
+
+<p>
+“I believe you are half glad of it,” snarled her escort as he brought the
+machine to a stop and repeated his usual question.
+</p>
+
+<p>
+“Sure there was a car with two men in it like you describe passed here,” the
+man replied to their amazement and delight. “They stopped here for gas, as they
+generally do. About three hours ago, I guess it musta been.”
+</p>
+
+<p>
+Dean shot a triumphant glance at Jane.
+</p>
+
+<p>
+“An old man with a gray beard and a smooth-shaven young man driving—does that
+describe them?” he repeated.
+</p>
+
+<p>
+“That’s them,” said the garage proprietor. “They come through here every few
+days, always about the same time.”
+</p>
+
+<p>
+“Where do they go?” questioned Dean eagerly, feeling at last that the scent was
+growing hot.
+</p>
+
+<p>
+The man shook his head in a puzzled way.
+</p>
+
+<p>
+“I’ve often wondered about that. They’re always heading south and appear to be
+in a powerful hurry, but the funny part of it is I ain’t never seen them coming
+back.”
+</p>
+
+<p>
+“Do you know their names?”
+</p>
+
+<p>
+“No, I can’t say I do, though it seems as if I’d heard one of them called Fred.
+I can’t say which it was.”
+</p>
+
+<p>
+“Do they always come by on the same day—on Wednesday?” asked Jane, forgetful
+once more of Dean’s warning to let him do the talking lest her voice should
+betray her sex.
+</p>
+
+<p>
+“Come to think of it,” said the man, apparently noticing nothing unusual, “I
+guess it always is on a Wednesday they come by.”
+</p>
+
+<p>
+“Is the number of their car anything like this?” asked Dean, exhibiting an
+entry in his notebook.
+</p>
+
+<p>
+“I couldn’t say,” said the man, studying the figures. “I know it is a New York
+license, and the number ends with two nines like this one does. What might you
+be wanting them for?”
+</p>
+
+<p>
+He spoke to a cloud of dust, for Dean had started up the motorcycle before he
+finished speaking and already was speeding away.
+</p>
+
+<p>
+“Where now?” asked Jane.
+</p>
+
+<p>
+“I don’t know,” he answered frankly, “I only know we are going the direction
+the Hoffs went, and I want to gain on them before they get too far ahead. The
+chap back there had told us all he knew and was beginning to get curious, so I
+thought it better to vamoose.”
+</p>
+
+<p>
+“It’s funny about his never seeing them coming back.”
+</p>
+
+<p>
+“Probably there is nothing mysterious about that. I have a notion they always
+come up one side the river and down the other, taking the 125th Street ferry
+home. That would not be a bad plan to help them in eluding too curious
+observers. All these German spies are trained to leave as blind a trail behind
+them as possible. The thing we have got to discover is what brought them up
+here. We’ve just got to find out their destination.”
+</p>
+
+<p>
+“I am afraid there is little chance of our doing that,” insisted Jane. “We’ve
+nothing to go on.”
+</p>
+
+<p>
+“We’ve learned something. We know that their destination is somewhere between
+here and Fort Lee on this side of the river. That narrows down the search
+considerably. That’s more, too, than anybody else that the Chief has had on
+their trail has learned. Something tells me that we are getting warm right now.
+Obviously the place they come to must be nearer West Point than it is New York.
+They would hardly take too roundabout a course, even for the sake of hiding
+their tracks. Keep a sharp lookout for tire tracks leaving the main road.”
+</p>
+
+<p>
+The route they were following quickly led them into a sparsely inhabited
+mountainous district and instead of the concreted state highway they found
+themselves on a hilly dirt road, full of ruts and loose stones that made travel
+difficult. At times it was all Dean could do to manage the machine, so that he
+had to leave most of the task of observing the by-ways to Jane. For more than
+two miles they had seen neither house nor barn. Once or twice they came upon
+little used lanes leading off through the woods, but none of them showed any
+traces of the recent passing of an automobile.
+</p>
+
+<p>
+As they came dashing around a curve on a steep down-grade, where hardly more
+than the semblance of a road had been cut into the hillside, Jane caught her
+breath sharply. Above the roar of their own motor she thought she heard some
+other noise, something that sounded like another car near-by; yet neither
+behind nor ahead was there another automobile in sight.
+</p>
+
+<p>
+“Listen,” she cried sharply.
+</p>
+
+<p>
+Dean started to slow down, but it was too late. Out of a cut in the hillside,
+half screened by a clump of bushes at the side on which Jane was riding, a
+great gray motor shot out just as they were passing. Jane caught just one
+glimpse of the man on the driver’s seat. It was Frederic Hoff, frantically
+twisting at the wheel in an effort to avert the threatened collision. There
+came a thud and a crash as the forward part of the Hoff car struck the
+motorcycle a glancing blow, overturning it completely. Too terrified even to
+shriek, Jane felt herself being catapulted out of her seat and flung high in
+air. Then came a blank.
+</p>
+
+<p>
+Her companion did not escape so easily. The heavy machine crashed over on him
+and dragged him several yards. His head, as he landed in the roadway, struck a
+stone, and the motorcycle itself pinned him to the earth by its weight, one of
+his arms doubled up in an alarming fashion, as he lay there completely
+senseless.
+</p>
+
+<p>
+Jane fortunately had landed on some soft grass, though with sufficient force to
+leave her badly stunned. As she lay there, a boyish figure in her disguise, her
+senses began gradually to revive, although it was some time before she opened
+her eyes.
+</p>
+
+<p>
+Vaguely, as from a great distance, she began to hear voices, and it seemed to
+her that they were German voices, arguing about something. The voices seemed
+angry and excited. At first she did not bother about them. She was wondering
+how badly she was hurt. Her arms and limbs had a curious sort of deadness about
+them, a detached sensation, as if they belonged to some one else. She wondered
+if she was paralyzed and dared not try to move them, fearful lest she might
+find that it was the terrible truth.
+</p>
+
+<p>
+The voices—the German voices—came nearer, became louder and more strident. She
+struggled to collect her thoughts. Where was she? What had happened? Where was
+Thomas Dean? Gradually some memory of the accident came to her. They had been
+run down by the Hoffs’ car. The voices she kept hearing were those of the two
+Hoffs, angrily wrangling about something. As she revived further she became
+acutely conscious that her head seemed to be splitting. What was it the Hoffs
+were arguing about? Still lying there motionless, with her eyes closed,
+endeavoring to collect herself, she tried to listen to what they were saying.
+</p>
+
+<p>
+“I tell you there is not time. I must hurry. Every minute is precious. I cannot
+delay my work for these swine, no matter if they both are dying or dead,” old
+Otto was angrily shouting with many German oaths.
+</p>
+
+<p>
+“I tell you,” Frederic was saying,—his voice was calmer but determined,—“we’ve
+got to get these people to a doctor. It’s too heartless. I will not leave them
+here.”
+</p>
+
+<p>
+“And betray us at the last moment, when our plans are all ready,” snarled old
+Otto.
+</p>
+
+<p>
+“There is less danger if we bundle them into the car and take them with us than
+if we leave them here,” protested Frederic. “Two bodies right here at the
+entrance would be fine, <i>nicht wahr?</i>”
+</p>
+
+<p>
+His last remark appealed to old Otto.
+</p>
+
+<p>
+“That is so,” he muttered. “It is not safe. We must hide the bodies, both of
+them, yes?”
+</p>
+
+<p>
+The bodies! Jane decided that Dean must have been killed and that they thought
+that she, too, was dead. As she strove to open her eyes she could hear Frederic
+protesting.
+</p>
+
+<p>
+“It’s inhuman,” he cried. “They both are hurt, but perhaps still alive. We must
+take them to a hospital.”
+</p>
+
+<p>
+“And endanger all our plans,” stormed old Otto. “Throw them into the woods.”
+</p>
+
+<p>
+“We’ll do nothing of the sort,” Frederic insisted, his voice becoming unusually
+stern and severe. “I’m going to get both of these people to a doctor at once, I
+tell you.”
+</p>
+
+<p>
+With effort Jane opened her eyes and looked cautiously about. Where was Thomas
+Dean? How badly had he been hurt? The Hoffs’ automobile was slowly backing up.
+As she looked old Otto sprang out of it and righted the motorcycle. As he did
+so Jane saw the body of Dean lying senseless beneath it, but to him the old
+German paid no attention. He was examining the motorcycle and still sputtering
+that the swine should be left to rot.
+</p>
+
+<p>
+“We are going to take them with us in the car,” directed Frederic in a voice of
+authority. “I command it.”
+</p>
+
+<p>
+At the word old Otto’s mutterings ceased, though he shot a black look at the
+younger man.
+</p>
+
+<p>
+“This machine,” he suggested, “it is not hurt. I will take it and do our work.
+There is haste. You remain with the car. Do what you will with these people.”
+</p>
+
+<p>
+“Go then,” said his nephew curtly. “You can take the train at the first station
+and make time.”
+</p>
+
+<p>
+As the old man mounted the motorcycle and sped away Frederic sprang from the
+car, and approaching the spot where Dean’s body lay, began making an
+examination of his injuries.
+</p>
+
+<p>
+“Scalp wound, perhaps fractured skull, broken arm,” Jane heard him saying aloud
+to himself. She noted curiously that as soon as he was left to himself he began
+speaking in English.
+</p>
+
+<p>
+He left Dean and approached her. As he came nearer she closed her eyes again,
+trying to plan some course of action. Her head was throbbing so that she found
+it impossible to think. She felt toward young Hoff a warmth of gratitude for
+not having gone off and left them helpless as his uncle had insisted. Even
+though he was an enemy of her country, a man to be hated, a spy, she could not
+help being glad for his presence there. What would she have done without him,
+with Dean lying there injured and helpless on this lonely mountain road?
+</p>
+
+<p>
+“This chap seems only stunned,” she heard him say as he bent over her, then as
+he looked closer, she heard him exclaim:
+</p>
+
+<p>
+“My God, it’s Jane!”
+</p>
+
+<p>
+In an instant he was down at her side on his knees. Tenderly one of his arms
+went about her and lifted her head.
+</p>
+
+<p>
+“Miss Strong, Jane, Jane,” he implored, “Jane dear, speak to me.”
+</p>
+
+<div class="fig" style="width:100%;">

+<img src="images/illus04.jpg" width="464" height="650" alt="Illustration:" /></a>
+<p class="caption">“Thank God,” he cried. “Jane dear, tell me you are not hurt.”</p>
+</div>
+
+<p>
+Stunned though she still was a flush crept into Jane’s cheeks at the unexpected
+term of endearment, though she still kept her eyes closed. Gently he laid her
+back on the turf and hastened to the automobile, returning with a flask which
+he held to her lips. Slowly Jane opened her eyes.
+</p>
+
+<p>
+“Thank God,” he cried. “Jane dear, tell me you are not hurt.”
+</p>
+
+<p>
+For a moment she lay there, staring wonderingly at him as he bent over her
+imploringly, the tenderest of anxiety showing in every line of his face.
+Unprotestingly she let him slip his strong arm once more under her head. In her
+dazed brain there was a strange conflict of peculiar emotions. He was a German,
+a spy,—she hated him, and yet it was wonderfully comforting to her to have him
+there. Under other circumstances she could have loved him. He was so handsome,
+so masterful and so kind, too. He cared for her. Had he not called her “Jane,
+dear” in his amazement at finding her lying there? But she must not let herself
+think of him in that way. It was her duty, her sacred duty to trap him, to
+thwart his nefarious plans against her country. She must do her duty just as
+her soldier brother was doing his in far away France.
+</p>
+
+<p>
+Still supported by Hoff’s arms she sat up, trying to collect her thoughts and
+gingerly testing the movement of her arms and limbs.
+</p>
+
+<p>
+“Tell me,” he cried again, “Jane, dear, are you hurt?”
+</p>
+
+<p>
+“I don’t think so,” she managed to say.
+</p>
+
+<p>
+With his assistance she got up on her feet and walked uncertainly to the car,
+shuddering as she looked at Dean’s crumpled senseless body.
+</p>
+
+<p>
+“Your friend,” said Hoff, as he placed her in the forward seat and wrapped a
+rug about her, “I am afraid, is badly hurt.”
+</p>
+
+<p>
+“It’s our chauffeur, Thomas Dean,” she explained confusedly.
+</p>
+
+<p>
+She had been wondering what she could say to Frederic to account for her
+presence there. It was unconventional at least for a girl to be motorcycling
+about the country dressed in man’s clothes with a chauffeur. Hoff must surely
+realize now that she had been shadowing him. She felt almost certain that he
+had known it from the very first, since that afternoon when he had overheard
+her telephoning about the “fifth book.” Yet never by word or manner had he
+betrayed the fact that he suspected her. Beyond his customary reserve in
+speaking about himself or his activities, there was nothing to indicate that he
+knew anything yet. Whatever she told him now she must be careful not to betray
+her mission. Perhaps even in spite of all that had happened she still might be
+able to aid Chief Fleck in trapping them.
+</p>
+
+<p>
+But did she really want to trap Frederic Hoff? Had Thomas Dean’s bitter charge
+that she was trying to protect him been true? Frederic Hoff loved her. She,
+yes—she had to admit it to herself—she was beginning to love him. Could she go
+on with it?
+</p>
+
+<p>
+Hoff had been busy lifting the unconscious Dean into the tonneau. As she
+watched him as he lifted up the body unaided she was conscious of admiration of
+his great strength.
+</p>
+
+<p>
+“Will he die?” she whispered.
+</p>
+
+<p>
+“I don’t know,” he answered. “He is badly hurt. We must get him to a doctor at
+once.”
+</p>
+
+<p>
+He stopped a moment longer to examine the car. Fortunately the glancing blow
+that it had struck the motorcycle had done no more damage than shatter one of
+the lamps and bend the mud guard. Soon they were moving rapidly in the
+direction of New York.
+</p>
+
+<p>
+“I think,” said Hoff, “we had better leave him in the care of the first doctor
+we come to. We can say that he is an injured motorcyclist we found lying in the
+road.”
+</p>
+
+<p>
+“And me?” asked Jane, almost fearfully.
+</p>
+
+<p>
+“I’ll take you back to the city with me.”
+</p>
+
+<p>
+“No,” she replied, “that won’t do. I ought to stay by him. Besides, if I return
+with you, it will be hard to explain.”
+</p>
+
+<p>
+He turned to look inquiringly at her and for a moment drove on in silence.
+</p>
+
+<p>
+“There’s nothing more you can do for the man once he is in competent medical
+hands, except to notify his people. Is he married?”
+</p>
+
+<p>
+“No,” said Jane, “he’s not married. I can tell his friends.”
+</p>
+
+<p>
+“Did your parents know about”—he hesitated—“about this trip with the
+chauffeur?”
+</p>
+
+<p>
+Jane blushed guiltily, wondering what he suspected of her. She hoped that he
+did not think she had a habit of going off on such journeys with the chauffeur.
+Even though the man at her side was officially her enemy she resented being put
+into a position that would cheapen her in his eyes.
+</p>
+
+<p>
+“No,” she replied, “they knew nothing about it.”
+</p>
+
+<p>
+Hoff drove on in silence. She had feared that he might ask her more
+embarrassing questions, might insist on knowing where she had been going when
+the accident occurred. A panic seized her. What if he should ask her? What
+could she tell him? He had a masterful way about him. If he took it into his
+head to make her confess she realized that she would have a struggle to keep
+from telling him everything. She made up her mind that she would not, she dare
+not answer any more questions.
+</p>
+
+<p>
+When he spoke again she was relieved to hear a suggestion instead of a query.
+</p>
+
+<p>
+“When we have crossed the ferry,” he said, “you can put on a dust coat to hide
+your costume, and I will send you home in a taxi. Will that be all right?”
+</p>
+
+<p>
+“That will do nicely,” she replied, gratefully conscious that he was
+endeavoring to plan so that her part in the afternoon’s adventures need not
+become public.
+</p>
+
+<p>
+Nevertheless she waited nervously while Hoff and the doctor carried Dean into
+the doctor’s home. What if the doctor’s suspicions should be aroused, and he
+should insist on knowing all the details of the accident? To her astonishment
+the doctor seemed to accept Hoff’s brief recital of finding an injured
+motorcyclist on the road without question. Perhaps if she had seen the amount
+of the bills Hoff left to care for the chauffeur’s treatment she might have
+understood better.
+</p>
+
+<p>
+Yet unconscious though Dean had lain all the way, as they resumed their journey
+without him, she felt a sudden sense of dread at being alone in the car with
+Frederic Hoff. It was not that she longer feared he would endeavor to make her
+tell her reasons for the expedition. She was afraid that with just the two of
+them alone in the car he might seize the opportunity to declare his affection
+for her.
+</p>
+
+<p>
+But, to her amazement, he hardly spoke a word to her on all the rest of the
+journey homeward. Once in a while as she ventured a glance in his direction,
+annoyed a little perhaps by this neglect of her, she saw only a strong face set
+in lines of thought, his brow wrinkled in deep perplexity, and his blue eyes
+looking steadily at the road ahead—and at something far, far beyond.
+</p>
+
+<p>
+Save for an occasional solicitous question about her comfort he did not speak
+again until just after he had put her in a taxi at the ferry. As Jane was
+trying to say her thanks he leaned forward unexpectedly, his tall frame
+blocking the whole doorway.
+</p>
+
+<p>
+“Jane,” he said, his voice vibrant with emotion, “Jane, you must trust me.
+Everything must come out all right. Some day—some day soon when we have won—I
+am coming to find you and tell you that I love you.”
+</p>
+
+<p>
+“When we have won!” Jane shuddered and drew back in the car, aflame with sudden
+wrath.
+</p>
+
+<p>
+She had read and had heard often of the unspeakable conceit of the Prussians.
+She knew that they regarded themselves as supermen who could not be defeated.
+Her challenged American pride rose to battle. As she rode home she was sure now
+that more than she hated anything else in the world she hated Frederic Hoff,
+the spy, the German, who had dared to boast to her that they expected to win.

+<h2><a name="CHAPTER_XII"></a>CHAPTER XII<br/>
+PUZZLES AND PLANS</h2>
+
+<p>
+Chief Fleck had spent a sleepless night trying to put two and two together.
+Instead of the answer being “four” as it should have been each time he
+completed his figuring the result was “zero.” Time and again he mustered the
+facts into columns, only to succeed in puzzling himself the more.
+</p>
+
+<p>
+Two German spies, the Hoffs, had set out together in their motor on their usual
+mysterious Wednesday mission. Two other persons, two of his most intelligent
+operatives, Thomas Dean and Jane Strong, had set out on a motorcycle to shadow
+them.
+</p>
+
+<p>
+What had happened?
+</p>
+
+<p>
+Otto Hoff had returned to his apartment on foot, hours before his usual time,
+seemingly much perturbed about something.
+</p>
+
+<p>
+Frederic Hoff had arrived back at the apartment, also on foot, some hours later
+than usual, and the motor had not been returned to its usual garage. Frederic
+Hoff had appeared to be unusually elated about something.
+</p>
+
+<p>
+Thomas Dean was in a doctor’s home somewhere up the Hudson with a broken arm
+and a bad scalp wound and was unable to tell what had become of either Miss
+Strong or the motorcycle.
+</p>
+
+<p>
+Jane Strong had arrived home in a taxicab half an hour before Frederick Hoff,
+apparently unhurt but in a most peculiar condition of mind. When Chief Fleck
+had called her on the ’phone she had refused to answer any questions. The best
+he could get out of her was a promise that she would come to his office in the
+morning.
+</p>
+
+<p>
+From this situation Fleck’s shrewd and experienced mind had been wholly unable
+to make any satisfactory deductions. That something unforeseen and unusual had
+happened to the Hoffs he was certain. It was the first time on a Wednesday that
+they had not returned together. Whatever it was that had happened it had
+depressed old Otto and had been a cause of elation to Frederic. What could it
+have been? That was the poser.
+</p>
+
+<p>
+Coupled with this was the annoying fact of Jane Strong’s sudden reticence.
+Hitherto he had found her at all times ready and eager whenever he called on
+her—ready to do anything he asked her, or to tell him everything. Why had she
+suddenly balked? He recalled that Dean had hinted, and Carter, too, that the
+girl was becoming interested in the younger of the Germans, yet he scouted the
+possibility of Jane having gone over to the enemy’s side. A girl of her stock,
+living with her parents, with a brother fighting in France, never could be
+guilty of disloyalty, even if she were in love. Yet how was her disinclination
+to talk to be accounted for? After he had received a report that she was at
+home he had waited, expecting her to call him up. When she had not done so, he
+had called her. She had been positively curt and decisive. She had nothing to
+say to him, she had replied, at present. Dean was safe. She would come to his
+office in the morning. There was nothing for him to do but to await her
+arrival.
+</p>
+
+<p>
+He was expecting Carter, too. He had sent him to Nyack the evening before as
+soon as he had learned of Dean’s whereabouts. Carter was to find out everything
+that Dean had learned and report as soon as he could. It was Carter who arrived
+first.
+</p>
+
+<p>
+“Dean doesn’t know what happened to him, nor where the girl went,” said Carter.
+“They had lost the Hoffs’ trail at the Garrison ferry, as he told you over the
+’phone. They had to wait there half an hour for another boat. They scouted
+around West Point, and nearly three hours afterward they picked up the trail
+heading toward New York. About ten miles south of West Point they were clipping
+along a mountain road when something happened. Dean is not sure whether he hit
+a stone in the road or whether an automobile struck them. He was knocked
+unconscious and didn’t remember anything more until he came to and found the
+doctor setting his arm.”
+</p>
+
+<p>
+“Who took him to the doctor’s?”
+</p>
+
+<p>
+“It was a couple, the doctor said, who explained that they had found Dean lying
+in the road under his wrecked motorcycle. The doctor could not remember what
+the couple looked like. Said he had been too busy looking after the injured
+man. I did worm out of him, though, that the man had left two hundred dollars
+with him to take care of Dean.”
+</p>
+
+<p>
+“That’s funny,” said the chief.
+</p>
+
+<p>
+“It sure is,” said Carter. “Looks like hush money to me. What does the girl
+say?”
+</p>
+
+<p>
+“Nothing yet,” said Fleck. “She wouldn’t talk at all last night, but she’s
+coming here at ten.”
+</p>
+
+<p>
+“That’s funny,” said Carter. “Why wouldn’t she talk?”
+</p>
+
+<p>
+“I don’t know yet,” said Fleck decisively, “but I am going to find out. Do you
+really suppose that she has fallen in love with young Hoff?”
+</p>
+
+<p>
+Carter shook his head.
+</p>
+
+<p>
+“Dean thought so, and I know that Dean was in love with her himself, but I
+don’t know. I’d bank on that girl somehow, even if she is in love.”
+</p>
+
+<p>
+“There she comes now,” said the chief as he heard the door of the outer office
+open.
+</p>
+
+<p>
+As Jane entered she faced the two men almost defiantly. She too had had a
+sleepless night. Although she herself had been physically uninjured in the
+accident the shock to her nerves had left her unstrung, and besides she had
+been bothering all through the dark hours as to how much of what had happened
+in the last few hours it was her duty to tell to Chief Fleck.
+</p>
+
+<p>
+As her personal relations with Frederic Hoff and her feelings toward him had in
+no way affected her sense of duty she felt that it was unnecessary for her to
+report the declaration of love he had made to her. Surely an affair that
+involved only the heart was her own property so long as she faithfully reported
+anything and everything that might lead to the exposure of the Hoffs’ plots.
+She could not see that it was any of Chief Fleck’s business, nor her country’s
+either, if Frederic Hoff had fallen in love with her. At any rate it would be
+utterly impossible for her to make any statement about her own feelings toward
+him. Even in her own heart and mind she was not quite sure what they were. From
+the first his forceful personality had had great charm for her. His obvious
+interest in her she had found delightful and flattering. When she recalled how
+gallantly he had insisted on remaining to rescue Dean and herself, even before
+he knew her identity, she was filled with admiration for him. Yet always
+matched against all that she found lovable in him was the knowledge that he was
+a German, a traitor, a spy, perhaps a murderer, and at times she felt that she
+hated him with a hatred that never could be overcome.
+</p>
+
+<p>
+“Well,” said Fleck, studying her countenance, “what have you to tell us?”
+</p>
+
+<p>
+“How is Dean?” she asked. “Will he live?”
+</p>
+
+<p>
+Fleck and Carter exchanged glances. Was she, they wondered, really concerned in
+the handsome young chauffeur’s welfare, or had she merely put the question to
+gain time in framing what she was going to say?
+</p>
+
+<p>
+“I just left him,” said Carter, in response to an almost imperceptible nod from
+the chief; “he’s all right except for a scalp wound and a broken arm.”
+</p>
+
+<p>
+“I’m glad,” said the girl impulsively.
+</p>
+
+<p>
+“What happened to him?” asked Carter.
+</p>
+
+<p>
+“Don’t you know? The Hoffs’ automobile hit us and overturned the motorcycle.”
+</p>
+
+<p>
+“The Hoffs’ car!” cried Fleck and Carter together.
+</p>
+
+<p>
+“Yes, I thought you knew.”
+</p>
+
+<p>
+“Tell us everything,” demanded Fleck. “Where did it happen? Did they run you
+down purposely?”
+</p>
+
+<p>
+“I don’t think so; in fact I am sure they didn’t. It was entirely accidental.”
+</p>
+
+<p>
+“Where did it happen? All Dean could remember was that you had picked up their
+trail about ten miles south of West Point. He could not tell how the accident
+occurred. He didn’t even mention the Hoffs or seem to suspect that they were
+anywhere near at the time.”
+</p>
+
+<p>
+“I don’t think he saw their car at all,” Jane explained. “I caught just a
+glimpse of it before we were crashed into. We were on a mountain road going
+down a steep hill when their motor shot out of a deep cut just as we were
+passing.”
+</p>
+
+<p>
+“What happened then?”
+</p>
+
+<p>
+“I must have been stunned for a moment or two. When I regained my senses the
+Hoffs’ car had stopped, and Frederic was backing the car to where the accident
+had happened. His uncle was storming at him for stopping. He wanted Frederic to
+go on and leave us there, but Frederic wouldn’t do it, and they quarrelled.
+Frederic won out by pointing out that two bodies lying at the entrance would
+arouse suspicion.”
+</p>
+
+<p>
+“At the entrance to what?”
+</p>
+
+<p>
+“I don’t know. He didn’t say. I think I could find the place again.”
+</p>
+
+<p>
+“We’ve got to find it,” said Carter.
+</p>
+
+<p>
+“Indeed we have,” Jane agreed, “and quickly, too. I fear we are going to be too
+late. Old Mr. Hoff seemed to be in terrible haste and spoke of their plans
+being nearly completed.”
+</p>
+
+<p>
+“Go on,” said Fleck quietly, “tell us the rest.”
+</p>
+
+<p>
+“Frederic Hoff stayed behind to pick us up, and the old man went off on the
+motorcycle. I heard them talking about his taking a train at the nearest
+station.”
+</p>
+
+<p>
+“What did young Hoff do when he found it was you lying there?”
+</p>
+
+<p>
+“He seemed surprised and startled.”
+</p>
+
+<p>
+“What did he say?”
+</p>
+
+<p>
+Jane colored and hesitated. There rose in her mind the picture of his tall
+figure bending over her, with anguish in his eyes, with expressions of
+endearment on his lips. She could not, she would not tell them what he had
+said.
+</p>
+
+<p>
+“He asked if I was hurt.”
+</p>
+
+<p>
+“Is that all?”
+</p>
+
+<p>
+Again she blushed and hesitated.
+</p>
+
+<p>
+“That’s all.”
+</p>
+
+<p>
+“Did he not seem amazed at finding you there? Did he not ask you to account for
+your presence there?”
+</p>
+
+<p>
+“No,” said the girl, firmly, “he didn’t.”
+</p>
+
+<p>
+“Didn’t he question you at all?”
+</p>
+
+<p>
+“No,” she insisted, “he was busy getting Dean into the car. He was unconscious,
+and it looked as if he was badly hurt.”
+</p>
+
+<p>
+“Queer, mighty queer,” muttered Carter to himself.
+</p>
+
+<p>
+“Didn’t he ask you who Dean was?” questioned Fleck.
+</p>
+
+<p>
+“I explained that he was our chauffeur. He may have known him by sight at any
+rate.”
+</p>
+
+<p>
+“Go on.”
+</p>
+
+<p>
+“We stopped at the house of the first doctor we came to and left Dean there,
+and then Mr. Hoff brought me on home in the car. At the ferry he put me into a
+taxi.”
+</p>
+
+<p>
+“What did you talk about on the trip home?” asked Fleck suspiciously. “Didn’t
+he try to pump you?”
+</p>
+
+<p>
+“We hardly talked at all. He seemed concerned only in getting me home without
+its becoming known that I had been in an accident.”
+</p>
+
+<p>
+“Is that all?” asked the chief. She could see by his manner that he mistrusted
+her, that he felt that she was keeping something back.
+</p>
+
+<p>
+“We hardly exchanged a dozen words,” she insisted.
+</p>
+
+<p>
+Fleck shook his head in a puzzled way.
+</p>
+
+<p>
+“I can’t understand it at all,” he said. “Old Otto is a common enough type of
+German, painstaking, methodical, stupid, stubborn, ready to commit any crime
+for Prussia, but the young fellow is of far different material. He has brains
+and daring and initiative. He is far more alert and more dangerous. I cannot
+understand his finding you there and not trying to discover what you were
+doing.”
+</p>
+
+<p>
+“I can’t understand that either,” Jane admitted.
+</p>
+
+<p>
+“There’s no doubt in my mind,” the chief continued, “that Frederic Hoff is the
+real conspirator, the head of the plotters.”
+</p>
+
+<p>
+“Why do you say that?” asked Jane quickly. “What did you find out when you
+searched the apartment yesterday?”
+</p>
+
+<p>
+She felt certain from the manner in which he spoke that he must now have some
+damning evidence of Frederic Hoff’s guilt. He was not in the habit of making
+decisions without proof.
+</p>
+
+<p>
+“We found,” said Fleck, his keen eyes fixed on her face as if trying to read
+her innermost thoughts, “a British officer’s uniform hanging in Frederic Hoff’s
+closet, proof positive that he is a dangerous spy.”
+</p>
+
+<p>
+“And,” said Carter, pointing to the two clippings lying on Fleck’s desk, “in
+the old man’s waste-paper basket we found those.”
+</p>
+
+<p>
+Jane picked up the clippings and examined them curiously.
+</p>
+
+<p>
+“What are they?” she asked, looking from one to the other; “cipher messages of
+some sort?”
+</p>
+
+<p>
+“We think so,” said Carter. “We don’t know yet.”
+</p>
+
+<p>
+“I’ve noticed these peculiar advertisements often,” said Jane, studying the
+clippings, “but I never thought of connecting them with the Hoffs. I wonder—”
+Fleck and Carter had their heads together and were talking in low tones.
+</p>
+
+<p>
+“I wonder,” said the chief, “what young Hoff is up to. He must have known the
+girl was there to spy on him. I can’t understand his not quizzing her.”
+</p>
+
+<p>
+“He’s a cagey bird,” Carter replied. “They are both of them expert at throwing
+off shadowers. Both of them know, I think, they are being watched.”
+</p>
+
+<p>
+“Oh, listen,” interrupted Jane, all excitement. “I believe I can read this
+cipher. The number of letters in the word in big type at the beginning of the
+advertisement is the key. See, this word here is ‘remember’—that has eight
+letters. Read every eighth word in this advertisement. I’ve underlined them.”
+</p>
+
+<p>
+Fleck took the paper quickly from her hand and he and Carter bent eagerly over
+it to see if her theory was correct.

+THE SEALED PACKET</h2>
+
+<p>
+“Is this Miss Strong?”
+</p>
+
+<p>
+Jane, her face blanching, held the receiver in wavering hands for a moment
+before she could muster courage to answer. She had recognized Frederic Hoff’s
+voice speaking. What could he want with her now?
+</p>
+
+<p>
+“It is Miss Strong,” she managed to answer.
+</p>
+
+<p>
+“This is Frederic Hoff. May I come in for a moment? It is most important.”
+</p>
+
+<p>
+Again Jane hesitated. Frederic was the last person in the world she felt like
+seeing just at this moment. Only five minutes before she had arrived home from
+Chief Fleck’s office. She was under orders to hold herself in readiness to
+start immediately for the scene of yesterday’s accident. That this trip, unless
+their plans miscarried, would inevitably result in the exposure and disgrace of
+both the Hoffs she felt morally certain. To face on friendly terms the man
+whose downfall she was plotting, the man who only a few hours before had told
+her that he loved her, seemed a task far beyond her endurance, a situation too
+tragic for her to cope with.
+</p>
+
+<p>
+Duty, her duty to her country, her honor, her patriotism, her affection for her
+soldier brother, all bade her mask her feelings and seek one more opportunity
+of leading Hoff to betray himself in conversation if that were possible. Yet,
+to her own amazement and horror, her heart protested vigorously against such
+action. Harassed as she was by conflicting emotions, worn out by the trying
+experiences that had been hers the last few days, she realized at last that she
+was really in love with Hoff. The throb of joy that she had experienced at the
+sound of his voice, the thrill that came to her each time she saw him, the
+delight she found in his presence, the fact that despite all the circumstances,
+she wanted to be near him, to be with him, convinced her against her will and
+judgment that her heart was his. In vain she marshalled the damning facts
+against him. She tried to remember only the expression of murderous hate she
+had seen on his face the night that her predecessor, the other K-19, had been
+murdered. She tried to think of him only as a treacherous spy, an enemy of her
+country forever plotting to destroy Americans, yet she could not. However base
+and treacherous and low her reason told her Frederic Hoff must be, her
+refractory heart persisted in beating faster at the prospect of his coming.
+</p>
+
+<p>
+Hitherto not much given to self-analysis, she now found herself wondering at
+herself. What could be the matter with her? Why must she love this rascal? Why
+could she not fall in love with some decent, clean, patriotic young American,
+with some man like Thomas Dean? Chauffeur though he was now pretending to be,
+she knew that he was a college man, well-bred, and traveled. She knew, too,
+that Dean was in love with her. For him she had a sincere liking, great
+admiration even, and toward him now she was experiencing that feeling of
+sympathy a woman always has for the man she cannot love. But her feeling toward
+Dean, she classified as only that of friendship, nothing at all like the
+passionate affection that was rapidly drawing her closer and closer to Hoff.
+</p>
+
+<p>
+Dared she see him now? Might not her love for him overcome her high desire to
+be of service to her country? Might she not be led by her unruly heart into
+betraying to him the fact that he was in the most imminent peril?
+</p>
+
+<p>
+Yet she must see him, she told herself. Perhaps this very day he might be
+arrested and imprisoned. She might never again have the opportunity of seeing
+him alone and of talking with him. Into her troubled brain came a daring
+thought. Perhaps it was not too late, even yet, to turn him from his evil
+course. Was there, she wishfully wondered, any possibility of her leading him,
+through his love for her, to forsake his comrades, even to betray them? No, she
+admitted to herself, that was a preposterous idea. He was too dominating, too
+forceful, too determined, to be influenced to anything against his will.
+</p>
+
+<p>
+“May I come in, please?” he kept insisting over the ’phone.
+</p>
+
+<p>
+“Only for a minute,” she answered tremulously. “I’m going out soon. I have an
+engagement.”
+</p>
+
+<p>
+“I’ll come right over. I will not keep you long.”
+</p>
+
+<p>
+As she awaited his arrival, subconsciously desirous of looking her best in his
+presence, she stopped almost mechanically before her mirror to adjust her hair,
+letting him wait for her for a few minutes.
+</p>
+
+<p>
+He sprang forward to meet her as she entered the room where he was, his face
+beaming with delight at the sight of her.
+</p>
+
+<p>
+“Jane,” he cried, with a volume of meaning in the monosyllable, as seizing her
+hand, he held it tightly and gazed earnestly into her face.
+</p>
+
+<p>
+Bravely she tried to meet his gaze, to read in his face if she could the object
+of his unexpected visit, but her eyes fell before his, and the hot blood surged
+into her cheeks. Within her raged a desperate battle between her head and
+heart. Mingled with her unwelcome quickening of the pulse at his approach and
+admiration for his audacity in coming to her when he must know that she knew
+what he was, there was also an overwhelming sense of futile rage that he, a
+scheming German plotter, dared intrude his presence into an American home.
+</p>
+
+<p>
+“I’m glad to see you appear no worse for your accident,” he said, releasing her
+hand at last. “You got home all right, without attracting any one’s notice?”
+</p>
+
+<p>
+“Oh, yes,” she answered, trying to make her reply seem wholly indifferent and
+disinterested.
+</p>
+
+<p>
+“Your chauffeur is all right, too,” he went on. “I telephoned this morning. He
+had already left the doctor’s. There’s nothing more the matter with him than a
+broken arm and a scalp wound. That’s fortunate, isn’t it?”
+</p>
+
+<p>
+“Very fortunate,” she admitted.
+</p>
+
+<p>
+All at once as they stood there there seemed to have arisen between them an
+invisible, impenetrable barrier. They faced each other wordlessly, each
+embarrassed by the knowledge of the secret gulf that was between them. Hoff was
+the first to recover from it.
+</p>
+
+<p>
+“Come,” he said, “sit down. There is something I wish to say to you,—something
+of the utmost importance, Jane.”
+</p>
+
+<p>
+Still struggling with her emotions, Jane allowed him to place a chair for her
+and seated herself, striving all the while to crush back into her heart the
+warmth of feeling toward him that always overwhelmed her in his presence,
+endeavoring to present to him a mask of cold indifference. Yet her curiosity,
+as well as her affections, had been greatly stirred by his remark. What was it
+that he was about to say to her? Did he intend, in spite of the insurmountable
+obstacles between them, dared he, ask her to marry him? Tremblingly she waited
+for what he had to say.
+</p>
+
+<p>
+“Jane,” he said, “you know that I love you. I am confident, too, that you love
+me.”
+</p>
+
+<p>
+“I don’t love you,” she forced her unwilling lips to say. “I can’t. When our
+country is at war, when she needs men, brave men, how could any true American
+girl love any man who stayed at home, who idled about the hotels, who—”
+</p>
+
+<p>
+“Girl,” his voice grew suddenly stern and commanding, softening a little as he
+repeated her name, “Jane, dear, let me finish. I love you. There are grave
+reasons—all-important reasons—why I may not now ask you to be my wife.”

+<p class="caption">She could not bring herself to tell him, the man she loved,
+the thing she knew he was.</p>
+</div>
+
+<p>
+“I never could be your wife,” she cried desperately, “the wife of a—”
+</p>
+
+<p>
+The word died in her throat. She could not bring herself to tell him, the man
+she loved, the thing she knew he was.
+</p>
+
+<p>
+“My Jane,” he said, wholly unheeding her impassioned protest, “you know little
+yet of what life means in this great world of ours. You, here in your parents’
+home, sheltered, protected, inexperienced, have not the knowledge nor the means
+of judging me. You must take me on faith, on the faith of your love for me. For
+a woman, life holds but two great treasures, two loves—her husband’s and her
+children’s. With a man it is different. Love is his, too, but there is
+something more, something bigger—duty. Here in your country—”
+</p>
+
+<p>
+Even in her distress she caught his phrase “here in <i>your</i> country” and
+turned ghastly white. Always before in talking with her he had spoken of
+himself as an American. Did he realize, she wondered, that he had at last
+betrayed himself to her? Was he about to strip the mask from himself and his
+activities at last, and in the face of it all expect her, Jane Strong, to admit
+that she loved him?
+</p>
+
+<p>
+“Here in your country,” he went on placidly, “women forced by economic
+conditions have been driven from home into business, into politics, into
+office-holding, even into war activities. Longing for the clinging arms of
+little children they are striving to forget in assuming some part in the
+affairs that belong properly to men. But to the true woman love must ever mean
+more than duty, more than country. Those are words for men. A woman, if she
+would find happiness, must follow her heart, must forsake all for the man she
+loves. A woman’s duty is only to the man she loves, just as a man’s duty is to
+be true to himself, to his country.”
+</p>
+
+<p>
+“But,” she cried, “you told me you were American, that you were born here?”
+</p>
+
+<p>
+“Jane,” he persisted, with an impatient gesture, “we will not discuss that now.
+I love you. You must trust me in spite of everything. I know you will. You
+must. I can answer no questions. I can make no explanations. I can only say I
+love you. That must suffice.”
+</p>
+
+<p>
+“No, no,” she protested, almost sobbing.
+</p>
+
+<p>
+“I came here to-day,” he went on calmly, “to ask a favor of you.”
+</p>
+
+<p>
+“A favor,” she cried.
+</p>
+
+<p>
+Calming herself she forced herself to look into his face. There was something
+so monstrously unbelievable about his audacity that she could hardly believe
+her ears. What sort of a credulous stupid creature was he, she angrily asked
+herself, that in one breath he could all but confess to her that he was a spy
+and in the next beseech her to do him a favor. Yet there came to her now a
+remembrance of her duty to her country. She felt that she must mask her
+feelings toward him, that if she was to be of service she must endeavor bravely
+to lead him on. She must try to induce him to confide in her. Hard as her task
+might be, what was it compared to the work her brother and those other brave
+American boys had undertaken facing the fire of death-dealing guns, facing the
+terrible gas attacks, living for days and weeks in those terrible trenches?
+Reinforced by a sense of duty, she made a pitiable effort at cordiality as she
+asked:
+</p>
+
+<p>
+“What is it you wish of me?”
+</p>
+
+<p>
+From one of his pockets he had brought forth a small packet which he held out
+to her. In spite of her agitation she forced herself to study it observingly,
+making note that it was tied with strong cord and sealed in several places with
+red wax. Curiously, too, she noted that on it was written her own name.
+</p>
+
+<p>
+“Jane,” said Hoff, “to-night I am going away. I may be absent for only a day or
+two if all goes well, but it is possible I may never come back,—may never be
+able to see you again.”
+</p>
+
+<p>
+She caught her breath sharply. There was the solemnity of finality in his
+tones. Where was he going? What might happen to him? She realized that the
+journey he was about to make was in connection with the plot that she and Chief
+Fleck were seeking to uncover. Evidently he anticipated peril in what he was
+about to undertake. Suppose he should be trapped in the commission of some act
+inimical to America’s welfare? What would happen to him? He would be arrested,
+of course. More than likely he would be sent to prison. He might even be shot
+as a spy. What if she were the one responsible for his meeting a disgraceful
+death? How could she go on with it? She must warn him. She must try to persuade
+him to give up his plans. She tried hard to steady herself, to think calmly.
+She must listen to every word he was saying and try to remember it.
+</p>
+
+<p>
+“This little packet is for you,” he went on. “I want you to keep it safely. In
+case anything happens, in the event that within one month I have not returned
+and you have heard nothing of me, I wish you to open it and keep what it
+contains. Promise me that you will do what I ask.”
+</p>
+
+<p>
+In a panic of indecision she got up from her chair, trying to frame a score of
+questions, but none of them succeeded in passing the barrier of her trembling
+lips.
+</p>
+
+<p>
+“Promise me,” he said softly yet impellingly, as he placed the little packet in
+her hand and closed her fingers over it.
+</p>
+
+<p>
+“I promise,” she whispered, hardly knowing what she said.
+</p>
+
+<p>
+Quickly he caught her in his powerful arms. For just a second he held her
+there, his face close to hers, his blue eyes burning into hers with a steady
+inscrutable gaze as if he was trying to read in them the love her lips had
+refused to speak.
+</p>
+
+<p>
+Then, so quickly that it was all over before she quite realized what had
+happened, he had kissed her passionately full on the lips and was gone.
+</p>
+
+<p>
+Overcome with the lassitude which follows emotional crises, trembling in every
+limb, weak as from a long illness, the girl sank back into a chair, still
+clutching in her hand the sealed packet Hoff had entrusted to her. Minute after
+minute she sat there with staring eyes, with heart beating madly, with her
+whole body racked with the torment of her thoughts.
+</p>
+
+<p>
+Slowly she lifted the packet and turned it over and over, wondering what it
+could possibly contain, questioning herself as to what could have been Frederic
+Hoff’s motive in entrusting it to her. Was there, she wondered, under those
+seals, some evidence of his guilt and treachery that he had not dared to leave
+behind him? He must have known that she suspected him and was seeking to entrap
+him. Had he, knowing all this, but sensing the love for him that he had kindled
+in her, taken advantage of it and extorted from her her promise to keep it
+safe?
+</p>
+
+<p>
+Wherein lay her duty now? More than ever she was certain that Frederic Hoff was
+on some hazardous mission for the enemy. He had all but admitted his
+nationality to her. Her own country’s welfare demanded that the Hoffs’ plans
+should be discovered and thwarted. Should she, or should she not open the
+package? Possibly it contained some secret code, some clue to the dastardly
+activities in which he and his uncle were engaged.
+</p>
+
+<p>
+But her heart rebelled. She recalled what he had said, that she must take him
+on trust. The memory of his burning kiss, of that last earnest look he had
+given her, refused to be forgotten. Whatever he was, however base the work in
+which he was engaged, she knew down deep in her heart that Frederic Hoff had
+been earnestly sincere when he had said that he loved her.
+</p>
+
+<p>
+As she debated with herself what she ought to do, the telephone rang again. It
+was Chief Fleck.
+</p>
+
+<p>
+“Can you meet me at the 110th Street subway station in half an hour?” he asked.
+“I’ll be waiting in my car. Arrange it, if you can without arousing your
+family’s suspicion, to be away all night.”
+</p>
+
+<p>
+“I will be there,” she answered.
+</p>
+
+<p>
+As she turned away from the telephone with sudden resolve she thrust the sealed
+packet, still unopened, into the bosom of her gown.
+</p>
+
+<p>
+“I promised him,” she said almost fiercely. “I’ll keep my promise. That much at
+least I owe our love.”

+<h2><a name="CHAPTER_XIV"></a>CHAPTER XIV<br/>
+THE MOUNTAIN’S SECRET</h2>
+
+<p>
+In a turmoil of mental anxiety Jane waited the arrival of Chief Fleck at the
+place he had designated. She was still badly wrought up by the scene through
+which she had just passed with Frederic. There were moments when her heart
+insisted that, regardless of the despicable crimes that were laid at his door,
+she should forsake everything for him, for the man she loved. Had there been in
+her mind the slightest possible doubt as to his guilt she might indeed have
+wavered, but the evidence of his treachery seemed too manifest! She loathed
+herself for caring for him and felt it her sacred duty to go on with her work
+of aiding the government in trying to entrap both of them; yet how could she
+ever do it?
+</p>
+
+<p>
+As she waited she debated with herself whether or not to tell Chief Fleck what
+had passed between herself and Frederic. After all, why should she? That was
+her own secret, not the country’s. If she stifled her love, and gave her best
+efforts to aiding the other operatives in running down the conspirators, what
+more could be expected of her? Certainly she was not going to tell any one of
+the sealed packet Frederic had entrusted to her. She had promised him she would
+keep it safe. Surely there could be no harm in that, yet the little parcel,
+still in the bosom of her gown where she had thrust it, seemed to be burning
+her flesh and searing itself into her very soul.
+</p>
+
+<p>
+In strong contrast with her own spirit of martyrdom was Fleck’s manner. Never
+before had she seen him in such high spirits as he was when he drew up before
+the subway station in a low car built for speed. On the seat beside the
+chauffeur was a young man whom she recognized as another of the operatives. As
+Fleck swung the door of the tonneau open for her she noticed lying on the floor
+under a rug several rifles and drew back questioningly.
+</p>
+
+<p>
+“Come on, Miss Strong,” he cried gaily. “Don’t be afraid of them. We may be
+glad we have them before we return from our hunting expedition.”
+</p>
+
+<p>
+“But,” she asked hesitatingly as she took her seat beside him, “you don’t
+expect to shoot these men—without a trial.”
+</p>
+
+<p>
+Her heart seemed torn in anguish as she sensed anew the peril that lay ahead
+for Frederic. Misgivings that she might be unable to fulfil her task seized
+her, and she was smitten with reproach for her own conduct toward him. Why, an
+hour ago, when there was still opportunity, had she not warned Frederic? If he
+were really sincere in the affection he professed for her maybe she might have
+persuaded him, if not to betray his comrades, at least to abandon them and
+escape from the country. Yet even now her reason told her that any plea she
+might have made would have been worse than futile. Above and beyond his love
+for her she understood that he held sacred what he conceived to be his duty,
+his misguided duty to his erring country. It was too late now for regrets, for
+repentance, too late for her to do anything but to try to serve her country,
+cost her what it might, yet anxiously she awaited Chief Fleck’s reply to her
+question.
+</p>
+
+<p>
+“Wouldn’t I shoot them all on sight, gladly, the damned spies,” he responded.
+“That’s the great trouble with this country, Miss Strong. We’re too
+soft-hearted and chivalrous. The Germans realize that war and sentiment have no
+place together. If killing babies and destroying churches will in their opinion
+help them win the war they do it without compunction. The civilized world
+decided that poison gas was too brutal and dastardly for use, even against an
+enemy, but that didn’t stop the Huns from using it. They put duty to Germany
+above all else, and if their country expects it are ready to rob, murder, use
+bombs, betray friends, do anything and everything, comforted by the knowledge
+that even if we do catch them at it here in this country all we will do to them
+will be put them in jail for a year or two. If I had my way I’d shoot them all
+on sight.”
+</p>
+
+<p>
+“Without any evidence—without trying them?” questioned Jane.
+</p>
+
+<p>
+“Without trial, yes—without evidence, no; but in the case of these Hoffs we
+have evidence enough to stand them both up and shoot them.”
+</p>
+
+<p>
+“Have you learned more?” she asked quickly. “Is Frederic, too, involved with
+his uncle?”
+</p>
+
+<p>
+He shot an appraising glance at her. He had been inclined to regard Dean’s
+suspicion that she was in love with the younger Hoff as the mere figment of
+jealousy, but where two young persons of the opposite sex are thrown together,
+there is always the possibility of romance. Jane colored a little under his
+searching glance, yet what he read in her face seemed to satisfy his doubts,
+and he made up his mind to take her fully into his confidence.
+</p>
+
+<p>
+“Thanks to your quick wit in reading those advertisements,” he said, “we have
+now a fairly complete index of the Hoffs’ activities in the last six months. I
+have been spending the last two hours in going over all the Dento
+advertisements that have appeared. For weeks they have been sending out a
+regular series of bulletins.”
+</p>
+
+<p>
+“Bulletins about what?” asked Jane.
+</p>
+
+<p>
+“About everything of interest to the secret enemies of our country:
+explanations of where and how to get false passports, detailed statements of
+the sailings of our transports, directions for obtaining materials for making
+bombs, instructions for blowing up munition plants, suggestions for smuggling
+rubber, orders for fomenting strikes. They even had the nerve to use the name
+of William Foxley, signed to a testimonial for Dento.”
+</p>
+
+<p>
+“Who is William Foxley?” asked Jane curiously.
+</p>
+
+<p>
+“In the Wilhelmstrasse code that was in use when Von Bernstorff was still in
+this country; in sending their wireless messages they made frequent use of
+proper names which had a code meaning. Boy-ed was ‘Richard Houston,’ Von Papen
+was ‘Thomas Hoggson’ and Bolo Pascha was always mentioned as ‘St. Regis,’ In
+this same code ‘William Foxley’ always meant the German Foreign Office.”
+</p>
+
+<p>
+“But surely you did not learn this from the advertisements?”
+</p>
+
+<p>
+“Not at all. Hugo Schmidt, who was reputed to be the paymaster of the gang, was
+caught trying to burn a copy of this code at the German Club. With the records
+of their wireless messages our government managed to reconstruct the whole
+code. The use of a word or two from this code in these advertisements is most
+significant. It shows that whoever prepared these advertisements was high in
+the confidence of the German government. Only the very topnotch spies are
+likely to be permitted to know the diplomatic code.”
+</p>
+
+<p>
+“And you think, then, that Otto Hoff may be the head of the conspirators in
+this country?” said Jane.
+</p>
+
+<p>
+“Not Otto—Frederic,” said Fleck quickly. “The young man, I am certain, was the
+director, probably sent out from Berlin after the country became too hot for
+Von Papen and Boy-ed. The old man, I believe, merely carried out his orders. I
+doubt even if they are uncle and nephew.”
+</p>
+
+<p>
+“I think you are wrong about that,” protested Jane. “Whenever I was listening
+over the dictograph it was always the old man who was so bitter against
+America. It was he who talked about the wonder-workers and the necessity for
+haste. I never heard Frederic say anything—anything disloyal, that is.”
+</p>
+
+<p>
+“The fact that he knew enough to keep his mouth closed shows that he is the
+more intelligent of the two. Don’t forget, too, that at times he even dared to
+don the uniform of a British officer. You saw him yourself. Undoubtedly he is
+the more dangerous of the pair.”
+</p>
+
+<p>
+“But who read these advertisements?” asked Jane, seeking to change the subject.
+“For whom were the bulletins intended?”
+</p>
+
+<p>
+“It was one of their ways of keeping in communication with their thousands of
+secret agents all over this country. I wouldn’t be surprised if occasionally
+these advertisements were printed in Texas papers and shipped over the border
+into Mexico. We have been watching the mails and the telephone and telegraph
+lines for months, yet all the while Mexico has been sending messages across,
+telling the U-boats everything they needed to know. We never thought of
+checking up the advertising in papers in the Mexican mail.”
+</p>
+
+<p>
+“But what about the messages old Mr. Hoff left in the bookstores? Was that part
+of the plan, too?”
+</p>
+
+<p>
+“It may have been simply a duplicate method of communication in case the other
+failed. The Germans here know that they are constantly watched and take every
+precaution. We’ll land that girl as soon as we have the Hoffs safe behind the
+bars, and then we’ll soon see if Carter’s dachshund theory was right.”
+</p>
+
+<p>
+“But who,” asked Jane, “is the spy in our navy? Who signalled the Hoffs’
+apartment and supplied them with the news about our transports? Was it
+Lieutenant Kramer?”
+</p>
+
+<p>
+“Probably,” said Chief Fleck carelessly, “that is not my end of the work. It is
+up to the Naval Intelligence Bureau to clean out the spies in the navy. I’m
+after the boss-spy. After we land him it will be easier to get the small fry. A
+defiant German prisoner once boasted to me that Germany had a man on every
+American ship, in every American regiment, and in every department in
+Washington. I suspect it comes pretty near being true. A country that has so
+many citizens with German names and such an enormous population of German
+descent has its hands full.”
+</p>
+
+<p>
+As they talked the chief’s car had crossed the ferry, and turning north through
+Englewood, was heading rapidly in the direction of West Point.
+</p>
+
+<p>
+“Where are we going now?” Jane ventured to ask. “To the place where I was
+yesterday—where we had the accident?”
+</p>
+
+<p>
+“Not directly,” the chief replied. “I sent Carter and some men up there ahead
+of us to do some reconnoitering. I’ll get in touch with Carter at the
+restaurant at the State Park. He was to call me up. We are nearly there now.”
+</p>
+
+<p>
+As the car swung into the park and stopped before the entrance of the two-story
+restaurant building, Fleck sprang hastily out and started for the telephone but
+stopped abruptly at the sight of a young man with bandaged head and with one
+arm in a sling who rose from the concrete steps of the building to greet him.
+</p>
+
+<p>
+“Why, Dean,” he exclaimed in amazement, “what are you doing here? How did you
+get here?”
+</p>
+
+<p>
+“You don’t think I was going to be left out at the finish,” laughed the
+chauffeur.
+</p>
+
+<p>
+“But your injuries, your arm—”
+</p>
+
+<p>
+“Both all right, as right as they’ll be for several weeks.”
+</p>
+
+<p>
+“But how did you know we were coming here? How did you manage to get here?”
+</p>
+
+<p>
+“Carter stopped on his way out to make sure about the road. I wanted to come
+with him, but there was no room in his car. He refused to bring me, anyhow. I
+managed to worm out of him what your plans were, and the doctor’s jitney did
+the rest.”
+</p>
+
+<p>
+“Well,” growled the chief, with simulated indignation, though secretly
+delighted with Dean’s show of spirit, “I suppose there’s nothing else to do but
+to take you along. Climb in there beside Miss Strong.”
+</p>
+
+<p>
+As Dean approached the car Jane rose in amazement.
+</p>
+
+<p>
+“Oh, Thomas, Mr. Dean,” she cried, “I’m so glad to see you. I was afraid
+yesterday that you had been badly hurt.”
+</p>
+
+<p>
+“It was a close shave for both of us,” he admitted, flushing with delight at
+the warmth of her greeting, “but what are you doing here? The Chief had no
+business to bring you on a trip like this.”
+</p>
+
+<p>
+All his affection for the girl had revived at this unexpected sight of her, and
+with a lover’s righteous anxiety he resented Fleck’s having exposed her to the
+probable perils of this expedition to the enemy’s secret lair.
+</p>
+
+<p>
+“They needed me,” she said simply, “to show them the way.”
+</p>
+
+<p>
+“That need exists no longer,” he protested, “since I am here. The Chief must
+send you back.”
+</p>
+
+<p>
+“Don’t be absurd,” she objected warmly.
+</p>
+
+<p>
+“But it is no place for a woman,” he insisted doggedly, kicking meaningly at
+the rifles on the floor of the car. “There may be a fight. These men are
+desperate and dangerous and more than likely will resist any attempt to arrest
+them.”
+</p>
+
+<p>
+“I want to be there to see it if they do,” said Jane calmly.
+</p>
+
+<p>
+“Please, won’t you, for my sake,” he begged, “go back home or at least wait
+here for us?”
+</p>
+
+<p>
+“I won’t,” said the girl doggedly.
+</p>
+
+<p>
+“I’ll ask the Chief to send you back.”
+</p>
+
+<p>
+“Don’t you dare,” she retorted hotly, resenting his air of protection toward
+her.
+</p>
+
+<p>
+She was glad for the presence of the two other men in the car. She sensed that
+it was only their being there that kept Dean from making a scene. There was
+nothing in his manner toward her now of the obsequious chauffeur. While she
+admitted to herself that there was no longer the necessity for his continuing
+in his fictitious character she strongly resented his loverlike jealousy for
+her welfare and welcomed the chief’s return, for she saw from his face, as he
+came running up to the car, that he had received some sort of news that had
+highly delighted him.
+</p>
+
+<p>
+Almost before he was in the car he had given orders to start, leaving no
+opportunity for Dean to make his threatened protest against Jane’s presence.
+</p>
+
+<p>
+“I got Carter on the ’phone,” Fleck explained hurriedly as they swung out of
+the park and turned northward. “He has succeeded in locating the place the
+Hoffs go every week. It is about three miles back off the road, over toward the
+river from the place where you two had that accident yesterday. Away off there
+in the woods in a deserted locality is a sort of club, the members of which are
+Austrians or Germans. They have given it out that they are health enthusiasts
+and mountain climbers, ‘Friends of the Air,’ they call themselves.”
+</p>
+
+<p>
+“Who are they really? What are they doing there?” asked Jane interestedly.
+</p>
+
+<p>
+“Carter has not had time yet to learn much about them. The place was some sort
+of a health resort or sanitarium that failed several years ago. Last summer it
+seems to have been taken over by this bunch of Germans. At times there are only
+two or three of them there, but recently the number has increased. Carter
+thinks there must be a dozen men there now.”
+</p>
+
+<p>
+“How did he locate the place?” asked Dean.
+</p>
+
+<p>
+“Carter is a real detective,” said the chief enthusiastically. “He reasoned it
+out that where there were Germans there must be beer. He scouted along the main
+road until he found a wayside saloon where, as he had shrewdly suspected, they
+got their liquid supplies. From the proprietor of the place and the hangers-on
+he had no trouble in getting the information he wanted without arousing their
+suspicions.”
+</p>
+
+<p>
+“Where is Mr. Carter now?” asked Jane.
+</p>
+
+<p>
+“He’s waiting for us a few miles up the road.”
+</p>
+
+<p>
+“He has only four men with him, hasn’t he?” questioned Dean.
+</p>
+
+<p>
+“That’s all.”
+</p>
+
+<p>
+“And there are four of us here.”
+</p>
+
+<p>
+“Three and a half,” said the chief, motioning to Dean’s bandaged arm.
+</p>
+
+<p>
+“It’s my left arm,” he retorted. “I can handle a revolver, at least, with my
+good arm.”
+</p>
+
+<p>
+“And I can shoot, too,” boasted Jane; “that makes nine of us.”
+</p>
+
+<p>
+“Nine of us against twelve of the enemy,” said the chief thoughtfully. “It
+looks like a busy evening.”
+</p>
+
+<p>
+“And don’t forget,” warned Jane, “that the Hoffs are coming up this evening. At
+least young Mr. Hoff told me this morning that he was going away this evening.
+That makes two more on the other side.”
+</p>
+
+<p>
+“And one of them,” muttered Fleck, “a mighty dangerous man.”

+<h2><a name="CHAPTER_XV"></a>CHAPTER XV<br/>
+THE HOUSE IN THE WOODS</h2>
+
+<p>
+At last they had reached their goal, the place which the two spy suspects
+undoubtedly had been in the habit of visiting regularly every week for months
+past.
+</p>
+
+<p>
+Sheltered by a great rock and the underbrush about it, Jane, with Fleck and
+Thomas Dean, peered eagerly out at a dingy, weather-beaten frame structure
+which neighborhood gossip had told them was the sheltering place of the
+“Friends of the Air.” In its outward appearance at least, Jane decided, it was
+disappointingly unmysterious. It looked to her merely like a cheap summer
+boarding-house that had gone long untenanted. There was a two-story main
+building, cheaply constructed and almost without ornament, sadly crying for new
+paint, and the usual outbuildings found about such places in the more remote
+country districts.
+</p>
+
+<p>
+Still from Chief Fleck’s manner she was certain that he regarded their
+achievement in locating the place as of the highest importance. They had run
+their two automobiles noiselessly up the lane leading from the main road until
+they were perhaps half a mile distant from the house and then had concealed
+them in the woods near-by, being careful to obliterate all traces of the wheel
+tracks where they had left the lane. Making a d&eacute;tour among the trees
+they had reached their present position not more than three hundred yards away
+from the buildings. They had carried the rifles with them, and these now were
+close at hand, hidden under the log on which the three of them were sitting.
+Carter, with the other men, under Fleck’s orders, had divided themselves into
+scouting parties and had crept away through the woods to study their
+surroundings at still closer range while the waning afternoon light permitted.
+</p>
+
+<p>
+At first glance one might have been inclined to believe the buildings
+untenanted. There seemed to be no one stirring about the place, and some of the
+unshuttered windows on the second floor were broken. The only indications of
+recent occupation were a pile of kegs at the rear of the house and near-by a
+heap of freshly opened tin cans. Near one of the larger outbuildings, too, was
+a pile of chips and sawdust.
+</p>
+
+<p>
+“There does not seem to be any one about,” whispered Jane. “What do you suppose
+they do here?”
+</p>
+
+<p>
+“I can’t imagine yet,” said Fleck with an impatient shake of his head. “The
+fact that this house is important enough for the Hoffs to visit once a week
+makes it important for us to cautiously and carefully investigate everything
+about it. It may be a secret wireless plant away off here in the woods where no
+one would think of looking for it. It might be a bomb factory where their
+chemists manufacture the bombs and explosives with which they are constantly
+trying to wreck our munition plants and communication lines. Perhaps it is just
+a rendezvous where their various agents, the important ones engaged in their
+damnable work of destruction, come secretly to get their orders from the Hoffs
+and to receive payment for their hellishness accomplished.”
+</p>
+
+<p>
+“It’s all so funny, so perfectly absurd,” said Jane with a nervous little
+laugh.
+</p>
+
+<p>
+“Absurd,” cried Fleck indignantly, “what do you mean? It’s frightfully
+serious.”
+</p>
+
+<p>
+“Of course, I understand,” Jane hastened to say. “I was just thinking, though,
+how funny we are here in America, especially in the big cities. We know nothing
+whatever about our neighbors, about the people right next door to us. In one
+apartment we’ll be doing all we can to help win the war, and in the apartment
+next door the people will be plotting and scheming to help Germany win, and it
+is only by accident we find out about it. Take my own father and mother. They
+haven’t the slightest suspicion of the people next door. They would hardly
+believe me if I told them the Hoffs were German spies. They see them every day
+in the elevator. Young Mr. Hoff has been in our apartment several times. My
+mother has met him and talked with him. I was just thinking how amazed and
+horrified she will be when she hears about it and learns what I have been
+doing.”
+</p>
+
+<p>
+“You are perfectly right,” said Fleck soberly. “We are entirely too careless
+here in America about our acquaintances and neighbors. We know that we are
+decent and respectable, and we’re apt to take it for granted that everybody
+else is. We don’t mind our neighbors’ business enough. Nobody in a New York
+apartment house ever bothers to know who his neighbors are or what their
+business is, so long as they present a respectable appearance. I know New York
+people who live on the same floor with two ex-convicts and have lived there for
+three years without suspecting it. We should have here in America some system
+of registration as they have in Germany. Tenants and travelers ought to be
+required to file reports with the police, giving their occupation and other
+details. If that plan were in use here enemy spies would lack most of the
+opportunities we have been giving them.”
+</p>
+
+<p>
+“Yes,” said Dean, “you are right. I’ve lived in Germany. Over there a crook of
+any sort can hardly move without the police knowing it. Their system certainly
+has its good points.”
+</p>
+
+<p>
+“It surely has,” Fleck agreed. “If the Prussians’ character were only equal to
+their intelligence they would be the most wonderful people in the world, but
+they are rotten clear through. They have no conception of honor as we
+understand it. Only the other day I read of a Prussian officer who led his men
+in an attack on a chateau, guiding them by plans of the place he had made
+himself while being entertained in the chateau as a guest before the war.”
+</p>
+
+<p>
+“Don’t you think any of them have a sense of honor?” asked Jane in a troubled
+tone.
+</p>
+
+<p>
+Her mind had reverted, as she found it frequently doing, to Frederic Hoff and
+the sealed packet he had entrusted to her. He had professed to love her and had
+demanded that she trust him. Was it, she wondered, all a base pretense on his
+part? Was he—for Germany’s sake—taking advantage of her affection for him to
+make her the unwitting custodian of some secret too perilous for him to carry
+about with him? Perhaps that little parcel she was carrying in the bosom of her
+gown contained the code he and his uncle used? Had it not been for Dean’s
+presence she might have been tempted to take Fleck into her confidence and tell
+him of the peculiar incident, though in spite of all she knew about him she
+felt that Frederic Hoff’s feeling for her was real, and that toward her he
+always would show only respect and honor, as he always had done hitherto; and
+yet—
+</p>
+
+<p>
+Before the chief had time to answer her question Dean with a whispered “hist”
+pointed to a path in the rear of the buildings they were watching. Behind the
+house two rugged hills, their sides of precipitous rock so steep that they
+hardly afforded a foothold, came down close together, making a V-shaped cleft
+through which a narrow path ran in the direction of the river. Looking toward
+this cleft to which Dean was pointing they now saw a group of workmen
+approaching the house.
+</p>
+
+<p>
+All of them were in the garb of mechanics, yet as they approached in single
+file down the path, the quick eye of the chief noted that they were keeping
+step.
+</p>
+
+<p>
+“They’ve all of them seen service,” he muttered to himself, “either in prison
+or in the German army.”
+</p>
+
+<p>
+Some of them carried kits of tools, and they walked with the air of fatigue
+that results from a day of hard physical work. They seemed to have no suspicion
+as yet that they were under observation, for as they walked they chatted among
+themselves, the sound of their German gutturals reaching the watchers, but
+unfortunately not distinctly enough to be audible. Dean was busy counting them.
+</p>
+
+<p>
+“There are fourteen,” he announced, “two more than we were expecting to find
+here.”
+</p>
+
+<p>
+“At what do you suppose they are working?” asked Jane curiously.
+</p>
+
+<p>
+“Here comes Carter,” replied Fleck. “Perhaps he can tell us. His face shows
+that he has learned something.”
+</p>
+
+<p>
+Carter, crawling rapidly but silently through the underbrush, approached
+breathlessly, his sweaty, begrimed countenance ablaze with excitement.
+</p>
+
+<p>
+“What’s up?” asked Fleck, as soon as he was within hearing.
+</p>
+
+<p>
+“My God, Chief,” he gasped, “they’ve got three big aeroplanes out there on a
+plateau overlooking the river—three of them all keyed up and ready to start.”
+</p>
+
+<p>
+“Friends of the Air,” muttered Fleck; “so that’s what it means.”
+</p>
+
+<p>
+“They’ve evidently smuggled all the material up and built the three planes
+right here,” Carter went on. “I watched them putting on the finishing touches
+and testing the guy-wires. There is a machine shop, too, rigged up in one of
+those outbuildings. The thing that gets me is how they got the engines here.
+All the planes are equipped with powerful new engines.”
+</p>
+
+<p>
+“If there are traitors in the army and navy, why not in the aeroplane
+factories, too?” suggested Fleck. “A spy in the shipping department could
+easily change the label on even a Liberty motor intended for one of Uncle Sam’s
+flying fields. Even when it didn’t turn up where and when it was expected, it
+would take government red tape three months to find out what had become of the
+missing motors.”
+</p>
+
+<p>
+“These machines”—said Jane suddenly, “they must be the ‘wonder-workers’ old Mr.
+Hoff was always talking about.”
+</p>
+
+<p>
+“And that last advertisement we read,” Dean reminded them, “announced that the
+wonder-workers would be ready Friday. It looks as if we got here not a minute
+too soon.”
+</p>
+
+<p>
+“You bet we didn’t,” said Carter. “Every one of those three planes is fairly
+loaded down with big bombs, scores of them.”
+</p>
+
+<p>
+“To bomb New York,” said Fleck soberly; “that’s their plan. Zeppelins for
+England, big guns to shell Paris, bombs from the air for New York. It’s part of
+their campaign to spread frightfulness, to terrorize the world. Undoubtedly
+that is the reason Berlin sent Frederic Hoff over here, to superintend the
+destruction of the metropolis. There have been whispers for months and months
+that the city some day was to be bombed, but we never were able to discover
+their origin.”
+</p>
+
+<p>
+“And not a single anti-aircraft gun or anything in the whole city to stop them,
+is there?” cried Jane. “Wouldn’t it be terrible?”
+</p>
+
+<p>
+Fleck smiled grimly.
+</p>
+
+<p>
+“Any foolhardy German who tries to bomb New York from the air has a big
+surprise coming to him—a lot of big surprises. The war department may not have
+been doing much advertising, but it has not been idle.”
+</p>
+
+<p>
+“Then we have some anti-aircraft guns!” cried Jane delightedly. “I never heard
+anything about them.”
+</p>
+
+<p>
+“That would be telling government secrets,” said Fleck, smiling mysteriously,
+“but I’d just like to see them try it. I have sort of a notion to let them
+start their bombing.”
+</p>
+
+<p>
+“Oh, no, we mustn’t,” Jane insisted. “We mustn’t let those aeroplanes ever
+start. Can’t we do something right away to cripple them?”
+</p>
+
+<p>
+“There’s plenty of time,” the chief assured her. “It is best for us to wait
+until after dark. The early morning would be ideal time for an aerial attack on
+the city, when everybody is helpless and asleep. There’s generally a fog over
+the river and harbor, too, before sunrise at this season of the year, and that
+might help them to mask their movements. It would take an aeroplane less than
+an hour to reach the city from here, so that there is no likelihood of their
+starting until long after midnight. That gives us plenty of time, and besides
+we must wait until the Hoffs arrive.”
+</p>
+
+<p>
+“That will make two more—sixteen of them against our nine,” warned Dean.
+</p>
+
+<p>
+“We cannot help it how many of them there are,” said Fleck. “It is of vital
+importance for us to know just what their plans are. It is unlikely that they
+will post guards to-night in this secluded spot, where they have been at work
+in safety for months. As soon as it is dark we can smash the aeroplanes.”
+</p>
+
+<p>
+“That will be easy,” said Carter. “I know something about aeroplanes. Cut a
+couple of wires, and they are out of business. Sills, one of my men, is posted
+on bombs, and he’ll know just how to fix the fuses to render them useless.”
+</p>
+
+<p>
+“What’s more,” said Fleck, “if I understand German thoroughness, they will go
+over their final plans in detail to make sure that everything is understood.
+The darkness will let us slip up closer to the house, and we may be able to
+overhear what they say. Don’t forget, too, that our main job is to catch the
+Hoffs red-handed.”
+</p>
+
+<p>
+“That’s right,” said Dean. “They are the brains of the plot. These other
+fellows are just workmen taking orders.”
+</p>
+
+<p>
+“I’m puzzled,” said Fleck, “to know what they plan to do with the aeroplanes
+after the bombing has taken place. There is not one chance in a thousand of
+their being able to return here in safety without discovery. It will be sure
+death for the aviators that take up those machines.”
+</p>
+
+<p>
+“Sure death!”
+</p>
+
+<p>
+With a shudder Jane recalled what Frederic had said to her only a few hours ago
+as they parted—that he was going away and might never return. Was this what he
+had meant? Was he, Frederic, to be one of the foolhardy three who proposed to
+forfeit their lives in this desperate attempt to deal destruction from the air
+on a sleeping city, to wreck innocent homes, to cripple and maim and destroy
+helpless babies and women? She could not, would not believe it of him. That he
+had the courage and daring to undertake such a perilous task she did not doubt.
+She realized, too, that the controlling motive of all his actions was his high
+sense of duty toward his country, and yet in spite of all that she had learned
+about the plots in which she was enmeshed, her heart refused to believe that he
+ever could bring himself to participate in such wanton frightfulness. She
+recalled the spirit of mercy that he had shown toward herself and Thomas Dean
+after the accident as contrasted with the brutal indifference of his uncle. She
+kept hoping against hope that something might happen to prevent his arriving
+here. Devoutly she wished that she might awake and find that it was all a
+terrible mistake, a hideous unreality, and that the “Friends of the Air” were
+not in any way associated with the Hoffs.
+</p>
+
+<p>
+Yet her reason told her it must all be true, terribly, infamously true, and
+that he was one of them, perhaps the leader of them.
+</p>
+
+<p>
+One by one the members of the various scouting parties had come creeping in
+through the forest. All of them verified what Carter had already reported. One
+man, more venturesome than the others, had even dared to creep close up to the
+rear of the house and had seen through the window the workmen, gathered about
+their supper of beer and sausages, toasting the Kaiser with the unanimity of a
+set formality.
+</p>
+
+<p>
+As the light waned, secured from observation by the undergrowth between their
+position and the house, they sat there discussing plans of action, selecting
+while the light still permitted the most advantageous posts from which they
+could make a concerted rush on the plotters. Fleck was insistent that they
+should do nothing to betray their presence until after the Hoffs had arrived,
+and Dean once more voiced his protest against Jane taking part in the attack.
+“I will be of far more use than you with your crippled arm,” she resentfully
+insisted. “I can handle a revolver as well as any man, and a rifle, too, if
+necessary.”
+</p>
+
+<p>
+“Dean is right,” Fleck decided. “It is no work for a woman. Here is an
+automatic, Miss Strong. You will stay here until after we have rounded them up.
+If we get the worst of it, which is not likely to happen, make your way to the
+automobile and telephone the commandant at West Point.”
+</p>
+
+<p>
+Reluctantly Jane assented. She realized that further protest was useless. Fleck
+was in command, and his orders must be obeyed unquestioningly if their plans
+for the capture of the plotters were to be successfully carried out.
+</p>
+
+<p>
+Presently they heard in the distance the sound of an automobile approaching,
+and soon they could distinguish its lights as it negotiated the rough, winding
+woodland road that led to the house. A toot from the horn as it arrived brought
+the men within the house tumbling out the front door with huzzas of greeting
+for their leaders, and Fleck observed that all the men as they came out
+automatically raised their hands in salute.
+</p>
+
+<p>
+“Ex-German soldiers, every one of them,” he muttered.
+</p>
+
+<p>
+As the Hoffs got out of the car a shaft of light from the opened front door
+threw the figures of the new arrivals into sharp relief, and Jane saw, with a
+shudder of terror, that Frederic was dressed in an aviator’s costume. There was
+no longer any doubt left in her mind that he was one of those going to certain
+death, and a dry sob choked her.
+</p>
+
+<p>
+The Hoffs passed within the house, and the door was closed.
+</p>
+
+<p>
+“Now,” cried Fleck, “to your stations, men. Each of you take a rifle. You stay
+here, Miss Strong. Come on, Carter.”

+<h2><a name="CHAPTER_XVI"></a>CHAPTER XVI<br/>
+THE ATTACK ON THE HOUSE</h2>
+
+<p>
+In accordance with instructions already issued two of Fleck’s men rushed for
+the front of the house, where with rifles ready they stood guard, while the
+others took cover in the shadow of one of the outbuildings a few feet distant
+from the rear entrance.
+</p>
+
+<p>
+Apparently the plotters had been so long undisturbed in their mountain fastness
+that they had ceased to take even the most ordinary precautions against
+surprise. So far as could be discovered they had posted no guards over the
+aeroplanes and their deadly cargo, nor at either of the two doors to the main
+building. Nevertheless Fleck, as he crept stealthily up to the building with
+Carter at his side, took out his automatic and held it in readiness, and Carter
+followed his example.
+</p>
+
+<p>
+There was no moon to reveal their movements as they approached the rear of the
+house. The evening was warm, and one of the windows had been left open.
+Noiselessly they crept up to it and looked within. It opened into a large room
+used as a dining hall, where they could see all of the men clustered about one
+of the tables, at the head of which sat old Otto Hoff with Frederic at his
+side. On the table before him was what appeared to be a rough map or blueprint.
+Frederic and five of the other men, Fleck observed, now wore aviation costumes.
+</p>
+
+<p>
+“Comrades,” old Otto was saying in German, “here is the course. You will have
+no difficulty in following it. Down the river straight till you see the lights
+of New York. You each understand what you are then to do, yes?”
+</p>
+
+<p>
+“Certainly,” three of the men, the pilots evidently, responded.
+</p>
+
+<p>
+“Let us, to make sure,” old Otto insisted, “once more rehearse it. Much there
+is at stake for the Fatherland. You, Anton and Fritz, will blow up the
+transports and the warships that guard them. Six great transports are lying
+there, ready to sail at daylight The troops went aboard to-night. We waited
+until it was signalled that it was so. You must not fail. The biggest of those
+transports once belonged to Germany. You must teach these boastful Americans
+their lesson. That one boat you must destroy for certain. Beside the transports
+to-night lie five vessels of war, two battleships, three cruisers. Them you
+must destroy also, if there is time. To each transport, two bombs, to each
+warship, two bombs—twenty you carry. If all goes well, two you will have left.
+With these do what you will, a house, a church, it matters not—anything to
+spread the terror of Germany in the hearts of these money-grabbing Americans.”
+</p>
+
+<p>
+“It will be done,” said Anton solemnly.
+</p>
+
+<p>
+“I have thrown bombs before. You can trust me,” said Fritz.
+</p>
+
+<p>
+“You, Hans and Albert,” old Otto went on, “will fly over the city at good
+height. When you reach the end of the island you turn to the left, so, and come
+down close that your aim may not miss. Here will be the Brooklyn Navy Yard,”—he
+indicated a place on the map. “If there is fog the bridges will locate it for
+you. Smash the ship lying there, the shops, the dry docks; if it is possible
+blow up the munitions stored there.”
+</p>
+
+<p>
+“I know the place well,” Hans replied. “I worked there many months. I can find
+my way in the dark. It will be done.”
+</p>
+
+<p>
+“And to you, Herr Captain,” said Otto, turning to Frederic and saluting, “to
+you, whom the War Office itself sent here to oversee this all-wonderful plan of
+mine which it has seen fit to approve, to you and your mate falls the greatest
+honor and glory. You—”
+</p>
+
+<p>
+A suppressed sob at his side caused Fleck to turn quickly and lay his finger on
+the trigger of his revolver. There, close beside him, listening to all that had
+been said, was Jane. Left alone in the darkness she had found it impossible to
+obey the chief’s orders and remain where she was. Every little sound about her
+had carried new terrors to her heart. Hitherto she had not felt afraid, but the
+solitude filled her mind with wild imaginings. She was seized, too, by an
+irresistible desire to know what part Frederic was playing in this drama of the
+dark. Was his life in peril? Were Fleck and Carter now gathering evidence that
+would bring about his conviction, perhaps his shameful death? She must know
+what was happening. Quietly she had stolen up to peer through the window.
+</p>
+
+<p>
+Fleck, as he recognized her, with an angry gesture of warning to be silent,
+turned back to hear what Otto was saying.
+</p>
+
+<p>
+“—you, Frederic, have the glory of leading the expedition, of bombing that
+damned Wall Street which alone has kept Germany from winning her well-deserved
+victory. You will destroy their foolish skyscrapers, their banks, their
+business buildings. Your work will end this way. You will strike terror into
+the cowardly hearts of these American bankers whose greed for money has led
+them to interfere with our great nation’s rightful ambition. You shall show
+them that their ocean is no protection, that the iron hand of our Kaiser is
+far-reaching. Do your work well, and they will be on their knees begging us for
+peace.”
+</p>
+
+<p>
+“God helping me,” said Frederic, “I will not fail in my duty to my country.”
+</p>
+
+<p>
+There was something magnificent in his manner as he spoke, something almost
+regal, and Fleck regarded him with a puzzled air. Who was he, this man who had
+been sent out from Germany on this mission—this man to whom even old Otto paid
+deference? Despite the assurance with which he had spoken Fleck had observed in
+Frederic an uneasiness, a watchfulness, that none of the others seemed to
+exhibit. He had the appearance of alertly listening, listening, for what?
+Fleck’s first thought was that he might have overheard the little cry that Jane
+had inadvertently given, but he quickly dismissed this theory. If Frederic had
+heard that sound it would have alarmed him, and the look in his eyes now was
+one of expectancy rather than of fear.
+</p>
+
+<p>
+Jane, too, was puzzled and distressed. With trembling hands she clutched at the
+sill of the window for support as she heard Frederic assent to old Otto’s plans
+for him. Her estimate of his character made it seem incredible that he would
+willingly lend himself to this work of wholesale murder, yet she could no
+longer doubt the evidence of her own ears. With overwhelming force it came to
+her that this man who so readily agreed to such bloody, dastardly work as this,
+must undoubtedly be also the murderer of that K-19 whose body had been found
+just around the corner from her home. Bitterly she reproached herself that she
+had allowed herself to care for him. Shamedly she confessed to herself that she
+still loved him—even now.
+</p>
+
+<p>
+“Your great work accomplished,” Otto continued, “remember your orders. Forty
+miles due east of Sandy Hook there will be lying two great submarines, waiting
+to take you off—not U-boats, but two of our powerful, wonderful new X-boats,
+big enough to destroy any of their little cruisers that are patrolling the
+coast, fast enough to escape any of their torpedo boats. How important the war
+office judges your work you may realize from this—it is the first mission on
+which these new X-boats have been dispatched. They are out there now. We have
+had a wireless from them. They are waiting to convey six heroes back to the
+Fatherland, where the highest honors will be bestowed on them at the hands of
+our Emperor himself. Herr Captain and Comrades—”
+</p>
+
+<p>
+He stopped abruptly, and there came into his face a pained look of surprise, of
+terror.
+</p>
+
+<p>
+<i>“Was is dass?</i>” he cried in alarm.
+</p>
+
+<p>
+One of Fleck’s men in hiding out there in the shadow of the building had been
+seized by an irresistible desire to sneeze.
+</p>
+
+<p>
+The terrifying suspicion that there had been some uninvited spectator outside,
+listening to their plotting, swept over the whole room. The whole company,
+hearing the sound that had alarmed old Hoff, arose as one man and stood tensed,
+stupefied with fear, gazing white-faced in the direction from which the sound
+had come.
+</p>
+
+<p>
+Fleck, rudely brushing Jane aside, dropped back from the window and blew a
+sharp blast with a whistle. At the sound his men came running up with their
+rifles ready.
+</p>
+
+<p>
+Inside, the man called Hans, seizing an electric torch, dashed to the door, and
+pulling it wide, rushed forth, his torch lighting the way before him. Before he
+even had time to see the men gathering there and cry an alarm, a blow from the
+butt of Carter’s revolver stretched him senseless on the stoop.
+</p>
+
+<p>
+“In the name of the United States I command you to surrender,” cried Fleck,
+springing boldly into the open doorway, revolver in hand; “the house is
+surrounded.”
+</p>
+
+<p>
+Instantly all within the room was confusion. Some of those nearest the door,
+seeing behind Fleck the protruding muzzles of the guns, promptly threw up their
+hands in token of surrender. Others bolted madly for the front door, only to
+find their egress there blocked by the rifles in the hands of the guard that
+Fleck had had the foresight to station there.
+</p>
+
+<p>
+Old Otto, the pallor of fear on his face giving away to an expression of
+demoniac rage, drew a revolver and aimed it straight at Fleck. Jane, who
+unbidden had followed the raiders as they entered and now was standing
+wide-eyed in the doorway watching the spectacle, was the only one to see that
+just as old Otto pulled the trigger his nephew, whether by accident or design,
+she could not tell, jostled his arm, sending the bullet wide of its mark.
+</p>
+
+<p>
+“Come on, men,” cried Fleck, advancing boldly into the room.
+</p>
+
+<p>
+Eight of the Germans, piteously bleating “Kamerad” stood against the wall near
+the door, their hands stretched high above their heads.
+</p>
+
+<p>
+“Guard these men, Dean,” cried Fleck, as with Carter close at his side he
+dashed into the fray.
+</p>
+
+<p>
+One man already lay senseless outside, eight had surrendered. Four had fled to
+the front of the house. That left only the two Hoffs and one other man against
+five of them. It was Fleck’s intention to try to overpower the trio before the
+four who had fled returned to aid them. Jane, amazed at her own coolness, stood
+beside Dean, her revolver out, helping him guard the prisoners.
+</p>
+
+<p>
+Frederic all the while had been standing by his uncle’s side, strangely enough
+appearing to take little interest or part in the battle. Old Otto, though,
+despite his years, was fighting with vigor enough to require both the work of
+Fleck and Carter to subdue him. Vainly he struggled to wrench himself free from
+their grasp and use his revolver again. Fleck’s strength pulling loose his
+fingers from the weapon was too much for him. As he felt himself being
+disarmed, in a frenzy he tore himself loose from both of them and seizing a
+chair, swung it with all his strength against the hanging lamp above the table
+that supplied the only light in the room.
+</p>
+
+<p>
+In an instant the room was in darkness. The four from the front, rushing back
+to aid their comrades in answer to old Otto’s cries, found themselves unable to
+distinguish friend from foe. Fleck’s men dared not use their weapons in the
+darkness. Back and forth through the room the opposing forces struggled, the
+air thick with cries and muttered oaths, the sound of blows making strange
+medley with the rapid shuffling of feet.
+</p>
+
+<p>
+Jane, remembering the electric torch that had been carried by the man Carter
+had struck down, felt her way to the door and retrieved it from his senseless
+fingers. Returning, she flashed it about the room, endeavoring to assist Fleck
+by its light. As she let the beam fall on Frederic she heard a muttered curse
+at her side and turned to see Thomas Dean aiming his revolver directly at the
+younger Hoff. With a quick movement she thrust up his arm, and the bullet
+buried itself in the wall above his head.
+</p>
+
+<p>
+“What are you trying to do,” snapped Dean; “help that damned spy to escape?”
+</p>
+
+<p>
+“He wasn’t trying to escape,” she angrily retorted. “Look—quick—mind your
+prisoners.”
+</p>
+
+<p>
+He turned just in time to see the Germans behind him lowering their arms. In
+another second they would have been on his back. At the sight of his brandished
+revolver, their arms were quickly raised again.
+</p>
+
+<p>
+Meanwhile Fleck’s men, guided by Jane’s light, were laying about them with
+their rifles clubbed. The plotters were at a disadvantage in not realizing how
+few there were in the attacking party. Fleck’s announcement that the house was
+surrounded had both deceived and disheartened them. When three of their number
+had been knocked senseless to the floor the others surrendered and joined the
+group that stood with hands up.
+</p>
+
+<p>
+To Fleck’s amazement it was Frederic Hoff who led in the surrender.
+</p>
+
+<p>
+“Watch that young Hoff,” he whispered to Carter. “I can’t understand his giving
+up so easily. It may be only a ruse on his part.”
+</p>
+
+<p>
+“Perhaps he’s afraid the girl will be hurt,” whispered Carter, but Fleck was
+not there to hear him, having dashed forward to where old Otto was still
+fighting desperately.
+</p>
+
+<p>
+Somehow in the melee the old man had again got hold of a revolver, and just as
+Fleck seized him he fired again. The bullet, aimed at Fleck, left him unharmed,
+but found a mark in Thomas Dean, who with a little gurgling cry, fell forward
+at Jane’s feet. Carter turned at once to guard the prisoners, as Fleck, with a
+cry of rage, felled old Hoff to the floor, harmless for the present at least.
+</p>
+
+<p>
+Sending one of his men to the other rooms in search of lamps Fleck soon had all
+the prisoners safely shackled, both hand and foot, none of them offering any
+resistance. Investigation showed that old Hoff in falling had struck his head
+in such a way that his neck was broken, killing him instantly. The three who
+had been clubbed were not seriously injured, and as soon as they revived were
+shackled as the others had been.
+</p>
+
+<p>
+Jane, seeing Dean collapse, had turned to aid him and for some time had been
+bending over him, trying to revive him. He had opened his eyes, looked up into
+her face and had tried to say something, and then had collapsed, dying right
+before her eyes.
+</p>
+
+<p>
+“Take the Hoffs’ car outside,” Fleck directed some of his men, “and bring up
+our two cars at once. Carter and I’ll guard the prisoners until you get back.
+There’s a county jail only a few miles away. The sooner we get them there the
+better it will be. It won’t take any court long to settle their fate. They got
+Dean, didn’t they?”
+</p>
+
+<p>
+“Yes,” said Jane, getting up unsteadily from the floor, “I think he’s dead.”
+</p>
+
+<p>
+Fleck bent to examine the body of his aide, feeling for the pulse.
+</p>
+
+<p>
+“Too bad,” he murmured. “That last bullet of old Hoff’s got him, but he died in
+a good cause.”
+</p>
+
+<p>
+Jane, brushing away the tears that came welling unbidden into her eyes, turned
+now for the first time since his surrender to look at Frederic.
+</p>
+
+<p>
+She had expected as she looked at him lying there shackled on the floor to read
+in his expression humiliation at his plight, grief at the failure of his effort
+to aid Germany, possibly reproach for her in having aided in entrapping him. To
+her amazement there was nothing of this in his face.
+</p>
+
+<p>
+As he lay there on the floor he was observing her with a tender look of love,
+and in his eyes what was still more puzzling was an unmistakable expression of
+triumph and happiness.

+<h2><a name="CHAPTER_XVII"></a>CHAPTER XVII<br/>
+SOMETHING UNEXPECTED</h2>
+
+<p>
+Bewildered by the rapidity with which such a succession of terrifying events
+had taken place, Jane sank dazedly into a chair, trying her best to collect her
+thoughts, as she looked about on the recent scene of battle. All of the German
+plotters had been overcome and captured. There, dead on the floor, lay the arch
+conspirator, old Otto Hoff, his clammy face still twisted into a savage
+expression of malignant, defiant hate.
+</p>
+
+<p>
+And there, too, a martyr to the country’s cause, lay Thomas Dean. A sob of pity
+rose in Jane’s throat as she thought of him, and the great tears rolled
+unchecked down her cheeks. He was so young, so brave, so fine. Why must Death
+have come to him when there was yet so much he might have done? With his talent
+and education, with his wonderful spirit of self-sacrifice, he might have gone
+far and high. Regretfully, she recalled that he had loved her, and with kind
+pity in her heart she reproached herself for not having been able to return to
+this fine, clean, American youth the affection she had inspired in him.
+</p>
+
+<p>
+Thomas Dean, she told herself, was the type of man she should have loved, a man
+of her own people, with her own ideals, a man of her country, her flag, and
+yet—
+</p>
+
+<p>
+There on the floor, not a dozen feet away from her, shameful circlets of steel
+girdling both his wrists and his ankles, lay the one man for whom she knew now
+she cared the most in all the world, the man she had just betrayed into Chief
+Fleck’s hands.
+</p>
+
+<p>
+Bitterly she reproached herself for not having tried to induce Frederic to
+escape. In mental anguish she pictured him—the man she loved—standing in the
+prisoner’s dock in some courtroom, branded as a spy, as a leader of spies,
+charged with an attempt to slaughter the inhabitants—the women and children—of
+a sleeping, unprotected city. With growing horror it came to her that in all
+probability she herself would be called on to testify against him. It might
+even be her evidence that would result in his being led out before a firing
+squad and put to an ignominious death.
+</p>
+
+<p>
+She dared not even look in his direction now. What must he be thinking about
+her? He had known that she loved him. In despair and doubt she wondered whether
+he could understand that she, too, had been influenced to perform her
+soul-wracking task by a sense of honor, of duty to her country equally as
+potent as that which had impelled him to participate in this terrible plan to
+destroy New York. Why had she not informed him that his plans were known to the
+United States Government’s agents? Surely she could have convinced him that his
+was a hopeless mission. The plot would have been successfully thwarted, and he
+would not be lying there in shackles, but, even though forced to flee, who
+knew, perhaps some day after peace had come, he might have been able to return
+for her. A great sob rose from her heart, but she stifled it back. She would be
+brave and true. She must be glad for those of her people that had been saved.
+</p>
+
+<p>
+But her parents! What would they say? Her father and mother soon now must learn
+that she had been deceiving them day after day. How horrified and amazed they
+would be to learn that the chauffeur she had brought into the household was in
+reality a government detective, and that she, their daughter, had been a
+witness of his tragic death. What would they think when they learned about her
+part in this gruesome drama that had just been enacted? They, serene in their
+trust in her, supposing she was at the home of one of her girl friends, were
+peacefully asleep in their quiet apartment. How horror-stricken her mother
+would be if she could have seen her daughter at this moment, alone at midnight
+in a mountain shack, one girl among a band of strange men—and two men stretched
+dead on the floor.
+</p>
+
+<p>
+And Frederic! Always her perturbed imaginings led back to Frederic, to the
+terrible fate that lay in store for him, to the awfulness of war that had put
+between them an impassable gulf of blood and guilt and treachery that, in spite
+of their love for each other, kept them at cross purposes and made them
+enemies. Why, she vaguely wondered, must governments disagree and start wars
+and make men hate and kill each other? What was it all for?
+</p>
+
+<p>
+In the midst of her mental wanderings she became conscious that Fleck was
+speaking to Carter.
+</p>
+
+<p>
+“I’ll stay here with Miss Strong and the prisoners,” he was saying. “While we
+are waiting for the men to return with the cars, you’d better make a search of
+the house.”
+</p>
+
+<p>
+“Why not wait until daylight for that?” suggested Carter.
+</p>
+
+<p>
+“It is not safe,” the chief objected. “To-night is the time to do it. A plot
+important enough to have the especial attention of the war office in Berlin
+must have many important persons involved in it. Somebody with money in New
+York, some influential German sympathizer, must have helped old Hoff set up
+these aeroplanes here and equip his shop. Some chemical plant supplied the
+material for those bombs. It must have taken hundreds of thousands of dollars
+to carry the plan to completion. Men rich enough and powerful enough to have
+put through this plot are powerful enough to be still dangerous. The minute
+word reaches the city that the plan has miscarried there will be some one up
+here posthaste to destroy or remove any damaging evidence we may have
+overlooked. Now is the time to do our searching.”
+</p>
+
+<p>
+“You’re right, Chief,” Carter admitted. “It would not surprise me if there is
+not a wireless plant here. I’ll soon find out.”
+</p>
+
+<p>
+“Let me help,” cried Jane.
+</p>
+
+<p>
+Her nerves were suffering from a sharp reaction. All through the excitement of
+the attack she had remained calm and collected, but now she felt that if she
+remained another minute in the same room with the two bodies, if she stayed
+near that row of shackled prisoners, if she should chance to catch Frederic’s
+eye, she either would burst into hysterical weeping or would collapse entirely.
+If only there was some activity in which she could engage it might serve to
+divert the current of maddening thoughts that kept overwhelming her. With
+something to do she might regain her self-control.
+</p>
+
+<p>
+“Please let me help Mr. Carter,” she begged.
+</p>
+
+<p>
+“Certainly,” said Fleck, “go ahead. You have earned the right to do anything
+you wish to-night.”
+</p>
+
+<p>
+Guided by the light of an electric torch Carter and she quickly made their way
+to the upper floor. In most of the rooms they found only cheap cots with
+blankets, evidently the sleeping quarters of the workmen, but in one of the
+rooms was a desk, and from it a ladder led to an unfinished attic. Boldly
+climbing the ladder and flashing their torch about they quickly located a
+high-powered wireless outfit. It was mounted on a sliding shelf by which it
+could be quickly concealed in a secret cupboard, but evidently the plotters had
+felt so secure from intrusion in their retreat that they had been in the habit
+of leaving it exposed.
+</p>
+
+<p>
+“I thought we’d find it,” said Carter exultantly. “It’s an ideal location, up
+here in the mountains. I’d better smash it at once.”
+</p>
+
+<p>
+“Wait,” warned Jane, thoughtfully, “they spoke of having received a wireless
+message from those dreadful X-boats lying there off the coast. If we could only
+find their code-book, perhaps—”
+</p>
+
+<p>
+“Right,” cried Carter, catching her idea at once.
+</p>
+
+<p>
+Together they descended to the room below and began ransacking the desk, Jane
+holding the light while Carter examined the papers they found.
+</p>
+
+<p>
+“Their system sometimes is bad for them,” said Carter. “Here’s a ledger with
+the names of all the men employed here and the amounts paid to each. And look,”
+he went on excitedly, “look what the stupid fools have done with their German
+methodicalness—here are entries showing all the supplies they obtained, from
+whom they got them and what they cost. There’s evidence here for a hundred
+convictions. We’ll just take that book along.”
+</p>
+
+<p>
+There was one small drawer in the desk that was locked. Ruthlessly Carter
+smashed the woodwork and pried it open. Its only contents was a small parcel, a
+folded paper in a parchment envelope. Hastily he drew forth the paper and
+studied it intently.
+</p>
+
+<p>
+“It’s a code,” he cried, “a naval code, evidently the very one they used to
+communicate with those boats. I’ll wager the Washington people even haven’t a
+copy of it. That’s a great find. Come on, we’ve got enough for one night.”
+</p>
+
+<p>
+“Do any of the men in our party understand wireless?” asked Jane as they
+descended.
+</p>
+
+<p>
+“Sure,” said Carter, “Sills does. He used to be the radio man on a battleship.”
+</p>
+
+<p>
+“Couldn’t he be left on watch here?” suggested Jane, “and try to signal those
+X-boats and keep them waiting until to-morrow night? Maybe by that time our—”
+</p>
+
+<p>
+“I get you,” cried Carter; “that’s a good idea. Explain it to the Chief.”
+</p>
+
+<p>
+As Jane unfolded her plan, suggesting the possibility of sending American
+cruisers out to search for the X-boats after Sills had lured them by false
+messages to the surface, Fleck heartily approved of it.
+</p>
+
+<p>
+“I’ll leave Sills here with one other man to guard the house,” he said. “We’ll
+have to let poor Dean’s body remain here for the present, too. We’ll need all
+the room in the cars for the prisoners.”
+</p>
+
+<p>
+There was still much to be done. While some of the men were unceremoniously
+carrying out the shackled prisoners and piling them in the cars, others, under
+Carter’s direction, crippled the three “wonder-workers” and dismantled them,
+carrying their dangerous cargo of bombs into the woods and concealing them.
+</p>
+
+<p>
+None of the prisoners, since the moment the shackles had been put on, had
+uttered a word. Sullen silence held all of them unprotestingly in its grip.
+Even Frederic kept his peace, though from time to time his glance roved about,
+seeking Jane, and always in his eyes was a strange look, not of defeat, nor of
+shame, but rather of exultant triumph. Jane still dared not trust herself to
+look in his direction, but Fleck and Carter, too, observed curiously the
+expression in his eyes. Was he, they wondered, rejoicing over Dean’s untimely
+end? Did he, with true Prussian arrogance, in spite of the failure of his plot,
+still dare to hope that with Dean out of the way, he might escape punishment
+and yet win Jane Strong? Even as they picked him up, the last of the prisoners,
+and put him in the rear seat of the chief’s car, his eyes still sought for
+Jane.
+</p>
+
+<p>
+It was long after midnight before the strange cavalcade left the mountain
+shack. Fleck’s car led the way, with the chief himself at the wheel, and Jane
+beside him. Crowded on the rear seat were Frederic and two other prisoners, and
+standing in the tonneau, facing them with his revolver drawn in case they
+should make an attempt to escape in spite of their shackles, was Fleck’s
+chauffeur. Carter was at the wheel of the second car with five prisoners and a
+man on guard, and the arrangement in the third car was the same. Six men and a
+girl to transport thirteen prisoners! Inwardly Fleck was congratulating himself
+on his forethought in having provided shackles enough to go around, for
+otherwise he surely would have had a perilous job on his hands.
+</p>
+
+<p>
+As they rode down the mountain lane, Jane rejoiced at the darkness that hid her
+face, both from Fleck and from Frederic on the seat behind. Now that there was
+no activity to distract her maddening thoughts once more paced in turmoil
+through her brain. She loved this man, and she was leading him to disgrace and
+death. She hated and despised him. He was a treacherous, dangerous enemy of her
+country whom she had helped to trap, and she was glad, glad, glad. No, no! She
+wasn’t glad. She loved him. He had given her that sealed packet and had charged
+her to keep it for him. He couldn’t be all bad. Why must she love him? Her mind
+told her he was a criminal, an enemy, a spy, a murderer, yet her wilful heart
+insisted that she loved him. How strange life was! She and Frederic loved each
+other. Why could they not marry and be happy? Why was War? Why must nations
+fight? Why must people hate each other? Was the whole world mad? Was she going
+mad herself?
+</p>
+
+<p>
+Slowly and carefully, Fleck, with his lights on full, had steered the
+automobile down the narrow roadway through the woods. He had just turned the
+car safely into the main road, and stopped to look back to see how closely the
+other cars were following. Suddenly from the wayside a dozen men in uniform
+sprang up, the glint of their guns made visible by the automobile lights.
+</p>
+
+<p>
+“Halt,” cried a voice of authority.
+</p>
+
+<p>
+The one glimpse he had caught of the uniform had conveyed to Fleck the welcome
+fact that the party surrounding him were Americans—cavalry troopers.
+</p>
+
+<p>
+“Chief Fleck,” he announced, by way of identification. “Who are you?”
+</p>
+
+<p>
+A tall figure in officer’s clothes sprang up on the running board and peered
+into Fleck’s face.
+</p>
+
+<p>
+“Thank God, Chief,” he said, “that it’s you.”
+</p>
+
+<p>
+“Colonel Brook-White,” cried Fleck in amazement, recognizing the voice as that
+of one of the officers in charge of the British Government’s Intelligence
+Service in America. “What are you doing here?”
+</p>
+
+<p>
+“Trying to round up some bally German spies,” explained Brook-White.
+</p>
+
+<p>
+“I’ve beaten you to it,” cried Fleck, with a note of triumph in his tone. “I’ve
+got them all here in shackles.”
+</p>
+
+<p>
+“Good,” said Brook-White delightedly. “I was fearful I’d be too late. There was
+delay in getting a message to me. As soon as I had it, I tried to reach you and
+couldn’t. I dared not wait but dashed up here in my car. I knew there were some
+American troopers camped near here, and I persuaded the commander to detail
+some of his men to help me. Did you really capture the Hoff chap, old Otto?”
+</p>
+
+<p>
+“He’s better than captured,” said Fleck. “He’s lying dead back there in the
+house.”
+</p>
+
+<p>
+“Good,” cried Brook-White. “He was infernally dangerous according to my
+advices—but Captain Seymour—where is he? Wasn’t he working with you?”
+</p>
+
+<p>
+“Captain Seymour?” cried Fleck in astonishment. “I never heard of him. Who’s
+Captain Seymour?”
+</p>
+
+<p>
+“He’s one of my chaps,” explained Brook-White. “Wasn’t it he who steered you up
+here?”
+</p>
+
+<p>
+“I should say not,” said Fleck emphatically.
+</p>
+
+<p>
+“Good Lord,” cried the British colonel excitedly. “You don’t suppose those
+bloody Boches got him at the last—after all he’s been through? I hope he’s
+safe.”
+</p>
+
+<p>
+“Don’t worry, Colonel Brook-White,” came the calm voice of Frederic Hoff from
+the rear seat. “Chief Fleck has me here safe in shackles with the other
+prisoners.”
+</p>
+
+<p>
+“God,” cried Fleck, in astonished perplexity. “Is Frederic Hoff a Britisher—one
+of your men?”
+</p>
+
+<p>
+“Rather,” said Brook-White. “Chief Fleck, may I present Captain Sir Frederic
+Seymour, of the Royal Kentish Dragoons.”
+</p>
+
+<p>
+But Fleck was too busy just then to heed the introduction, or to pay attention
+to the muttered “<i>Donnerwetters</i>” of indignation that burst from the lips
+of his other prisoners.
+</p>
+
+<p>
+Jane Strong had fainted dead away against his shoulder.

+WHAT THE PACKET CONTAINED</h2>
+
+<p>
+“But,” said Jane, “I can’t understand it yet. How did you, a British officer,
+happen to be living with old Otto Hoff? How did you ever get him to trust you
+with his terrible secrets?”
+</p>
+
+<p>
+Captain Seymour chortled gleefully. Now that he was arrayed in proper British
+clothes, once more comfortable in the uniform of his regiment and had his
+monocle in place and was with Jane again, everything looked radiantly
+different. Even his speech no longer retained its international quality but now
+was tinctured with London mannerisms.
+</p>
+
+<p>
+“Oh, I say,” he replied, “that was a ripping joke on the bally Dutchmen.”
+</p>
+
+<p>
+Jane eyed him uncertainly. He seemed almost like a stranger to her in this
+unfamiliar guise, though for hours she had been eagerly looking forward to his
+coming.
+</p>
+
+<p>
+The exciting developments of the night before still were to her very puzzling.
+She recalled Frederic’s identification of himself, and after that all was
+blank. When she had come to she had found herself in a motor being rapidly
+driven toward New York in the early dawn, with Carter as her escort. He had not
+been inclined to be at all communicative.
+</p>
+
+<p>
+“Let the Captain tell you the story himself,” said Carter. “He knows all the
+details.”
+</p>
+
+<p>
+“But when can I see him?” questioned Jane. “When,” she hesitated, remembering
+the shameful bonds that had held him, “when will he be free?”
+</p>
+
+<p>
+“He’s as free this minute as we are,” Carter explained. “It didn’t take the
+Chief long to get the bracelets off, after Colonel Brook-White had identified
+him. There’s a lot for the Captain to do still, but rest assured, he’ll waste
+no time getting back to the city to see you.”
+</p>
+
+<p>
+“I hope not,” sighed the girl.
+</p>
+
+<p>
+She was too weary, too weak from the revulsion of feeling that had come on
+learning that her lover instead of being a dastardly spy was a wonderful hero,
+to make even a pretense at maidenly modesty. She wanted to see Frederic too
+much to care what any one thought.
+</p>
+
+<p>
+Slipping into her home fortunately without arousing any of her family, she had
+gone to bed with the intention of getting a rest of an hour or two. Sleep, she
+was sure, would be impossible, for she felt far too excited and upset. Yet she
+had not realized how utterly exhausted she was. Hardly had her head touched the
+pillow before she was lost to everything, and it was long after noon when a
+maid aroused her to announce that Captain Seymour had ’phoned that he would
+call at three.
+</p>
+
+<p>
+As she dressed to receive him, she was wondering how she should greet him.
+Blushingly she recalled the impassioned kiss he had pressed on her lips—why it
+was only yesterday. It had seemed ages and ages ago, so much had intervened.
+Mingled with a shyness that arose from her vivid memories was also a shade of
+indignation. Why had he not told her? Did he not trust her? She resolved to
+punish him for not taking her into his confidence by an air of coldness toward
+him. Certainly he deserved it.
+</p>
+
+<p>
+Yet, when he arrived, so full of animation did he appear to be, that the lofty
+manner in which she greeted him apparently went unnoticed. He met her with a
+warm handclasp and anxious inquiries about how she felt after all the exciting
+events. Too filled with eagerness to know all the details of his adventures she
+had found it difficult to maintain her pose, and soon was seated cosily beside
+him, asking him question after question, all the while furtively studying him
+in his proper r&ocirc;le. As Frederic Hoff she had thought him wonderfully
+handsome and masterful. As Captain Sir Frederic Seymour, in his regimental
+finery, he was simply irresistible.
+</p>
+
+<p>
+“A joke?” she repeated. “Do explain, I’m dying to know all about it.”
+</p>
+
+<p>
+“It wasn’t half as difficult a job as one might imagine, you know. Our censor
+chaps at home have got to be quite expert at reading letters, invisible ink and
+all that sort of thing. Hoff for months had been sending cipher messages to the
+war office in Berlin. He kept urging them to act on his all-wonderful plan for
+blowing up New York. They decided finally to try it and notified old Otto they
+were sending over an officer to supervise the job.”
+</p>
+
+<p>
+“What became of him? The officer they sent over?”
+</p>
+
+<p>
+“Our people picked him off a Scandinavian boat and locked him up. They took his
+papers and turned them over to me. Clever, wasn’t it?”
+</p>
+
+<p>
+“And you took his name and his papers and came here in his place? Oh, that was
+a brave, brave thing to do.”
+</p>
+
+<p>
+“I wouldn’t say that,” said Seymour modestly. “I fancy I look a bit like the
+chap, and I speak the language perfectly.”
+</p>
+
+<p>
+“But it was such a terrible risk to take,” cried Jane with a shudder. “Suppose
+they’d found you out?”
+</p>
+
+<p>
+“No danger of that,” laughed Frederic. “Old Otto never had seen the chap who
+was coming. His real nephew, Frederic Hoff, whose American birth certificate
+was used, died years ago. Besides I had the German officer’s papers and knew
+just what his instructions were. The worst of it was when old Otto insisted
+every night on toasting the Kaiser, and when he kept trying to get me mixed up
+in his dirty schemes. I had to go through with the former once in a while, but
+on the latter, I—how do you Americans say it—just stalled along. My orders were
+to land him only on the big thing—his wonder-workers.”
+</p>
+
+<p>
+“But how did you explain to him that British uniform?”
+</p>
+
+<p>
+“Now that was really an idea. The old fellow was getting a bit cross and
+suspicious with me because he thought I wasn’t doing enough while they were
+getting his ‘wonder-workers’ ready. At one time he was so distrustful of me
+that he had me followed.”
+</p>
+
+<p>
+“Oh, yes, I know,” said Jane quickly. With a thrill she remembered the scene
+she had witnessed from her window the night K-19, her predecessor on Chief
+Fleck’s staff, had been murdered. In her relief at discovering that Frederic
+was no German spy, she had forgotten that for weeks and weeks she had all but
+believed him guilty of murder. Now, something told her, surely and confidently,
+that he could explain it all.
+</p>
+
+<p>
+“I saw you from my window one night before I met you,” she went on. “A man was
+following you, and you chased him around the corner.”
+</p>
+
+<p>
+“I remember that,” he said; “the poor chap was found dead the next morning. Old
+Otto killed him. The man had been following me, and I had imagined that he was
+one of old Otto’s spies and knocked him down. I couldn’t find anything on him
+to indicate who he was, so just as he was beginning to revive I left him and
+came on home. It seems old Otto had been watching him trail me. He followed
+along and shot the man. He gleefully told me about it the next day, the hound.
+I ought to have given him over to the police, but that would have upset our
+plans.”
+</p>
+
+<p>
+“I see,” said Jane; “what about Lieutenant Kramer? Was he working with old Mr.
+Hoff?”
+</p>
+
+<p>
+“That’s the funny part of it. Here in this country you’ve got so many kinds of
+secret agents they’re always trampling on each others’ toes. There’s your
+treasury agents, and your Department of Justice agents, and your army
+intelligence men and your naval intelligence men—nine different sets of
+investigators you’ve got, counting the volunteers, so some one told me, and
+each lot trying to make a record for itself and not taking the others into its
+confidence. Rather stupid I call it.”
+</p>
+
+<p>
+“I should say so,” agreed Jane.
+</p>
+
+<p>
+“Here was I watching old Hoff for our government, and Kramer watching me for
+your navy and Fleck watching both of us. It was a funny jumble.”
+</p>
+
+<p>
+“But about that uniform?” Jane persisted.
+</p>
+
+<p>
+“When the old man got to ragging me a bit, I felt I must do something to
+convince him I was all right. I suggested trying to get a British uniform and
+maybe learning thereby some secrets. It delighted him hugely. Of course I just
+went down to Colonel Brook-White and got my own uniform, and that was all there
+was to that.”
+</p>
+
+<p>
+“It puzzled Mr. Carter, though, how you got it in and out of the house. He used
+to open every bundle that came for Mr. Hoff.”
+</p>
+
+<p>
+Sir Frederic laughed delightedly.
+</p>
+
+<p>
+“I had a messenger who used to bring it back and forth in a big lady’s hat-box.
+It always was addressed to you, my dear, but the boy had instructions to
+deliver it to me.”
+</p>
+
+<p>
+“Humph,” snapped Jane with mock indignation. “And when did you first find out
+that I was helping Chief Fleck watch you?”
+</p>
+
+<p>
+“I suspected it from the start. Kramer told me how you’d become acquainted with
+him. Then when I heard you ’phoning Carter about the bookstore I knew for
+certain.”
+</p>
+
+<p>
+“Oh, that’s one thing now I wanted to ask about—those messages Hoff left in the
+bookstore. Who were they for?”
+</p>
+
+<p>
+“Instructions to a German advertising agency on how to word some advertisements
+that contained a code.”
+</p>
+
+<p>
+“Oh, those Dento advertisements?”
+</p>
+
+<p>
+“You knew about them?” cried Seymour in astonishment.
+</p>
+
+<p>
+“Of course,” said Jane proudly. “I was the one who deciphered them; but what
+did that girl do with those messages? Carter had a theory that she slipped them
+under a dachshund’s collar.”
+</p>
+
+<p>
+“That theory’s just like Carter,” laughed Frederic—“regular detective stuff. I
+never heard of any dachshund’s being used. The girl used to slip them into a
+letter box in her apartment-house hallway. Two minutes later a man would get
+them and carry them to their destination.”
+</p>
+
+<p>
+“The traitors in our navy—the men who signalled old Otto and Lena Kraus about
+the transports—who were they? They are the scoundrels I’d like to see arrested
+and shot.”
+</p>
+
+<p>
+“Never worry. They’ll all meet their deserts. I can’t tell even you who they
+are, but I’ve given your Chief Fleck a list of them. They will be quickly
+rounded up now. What else can I tell you?”
+</p>
+
+<p>
+“There’s this,” said Jane, the color rising to her cheeks as she drew forth
+from its hiding place in the bosom of her gown the packet he had entrusted to
+her the morning before, its seals still intact.
+</p>
+
+<p>
+“What?” he cried in delight. “You kept it safe? You did not open it even when
+you saw me arrested, when you must have been convinced that I was a spy? Girl,
+dear girl”—his voice became a caress, and the light of love flamed up in his
+eyes, “you did trust me then, in spite of everything.”
+</p>
+
+<p>
+“I had promised you, and I kept my promise,” faltered Jane, striving for words
+to explain, though she had been unable to explain her actions even to herself.
+“I think my heart trusted you all the time, even though my head and eyes made
+me believe you were what you pretended to be. Even when things looked blackest
+my heart persisted that you were true.”
+</p>
+
+<p>
+“God bless your heart for that,” cried Frederic, as he took the little packet
+from her hands and began breaking the seals. “Yesterday morning, when old
+Otto’s plans were ready, I foresaw the danger of the trip ahead of me. I
+realized I might never come back alive. If they discovered who I was a second
+too soon it would mean my death. I dared not, for my country’s sake, tell even
+you what I was doing. My honor was at stake. I dared not drop the slightest
+hint nor write a single line. The only thing I’d kept about me in the apartment
+that wasn’t filthy German stuff was what’s in here.”
+</p>
+
+<p>
+Slowly he was unwrapping something rolled in tissue paper, as Jane, eager-eyed,
+looked wonderingly on.
+</p>
+
+<p>
+“But,” he went on, “I couldn’t go away from you without leaving some token,
+some clue. If it happened that I never came back, I wanted you to know—”
+</p>
+
+<p>
+He stopped abruptly.
+</p>
+
+<p>
+“To know what?” questioned the girl breathlessly.
+</p>
+
+<p>
+“To know that I loved you, darling, better than all else save honor,” he said,
+taking her into his arms. “See the token I left behind for you. It’s an old,
+old family ring with the Seymour crest. You’ll wear it, girl of mine, won’t
+you, wear it always.”
+</p>
+
+<p>
+Unhesitatingly Jane Strong thrust forth the third finger on her left hand, and
+instinctively her lips turned upward toward his.
+</p>
+
+<p>
+And no matter what might have happened just then in the apartment next door,
+neither of them would have known anything about it.
