+
+CHAPTER I
+
+
+The big, mud-spattered touring car, which for the past hour had been
+plowing its way steadily northward from the city of Washington,
+hesitated for a moment before the gateway which marked the end of the
+well kept drive, then swept on to the house.
+
+A man, stoutly built, keen of eye, showing haste in his every movement,
+sprang from the machine and ascended the veranda steps.
+
+"Does Richard Duvall live here?" he inquired, curtly, of the smiling old
+colored woman who came to the door.
+
+"'Deed he do, suh. Does you want to see him?"
+
+"Yes. At once, please. Tell him it is most important. My name is
+Hodgman."
+
+The servant eyed him with cool disfavor. "Set down, suh," she remarked
+stiffly. "I'll tell him you is here."
+
+The caller watched her, as she disappeared into the house, then cast
+himself impatiently into a chair and lit a cigar.
+
+He paid no attention to the attempts of two clumsy collie puppies to
+attract his favorable notice, but contented himself with making a quick
+survey of the wide comfortable veranda, with its big roomy chairs, the
+wicker table, bearing a great jar of red peonies, the smooth green
+lawns, swept by the late afternoon sun.
+
+"Fine old place," he muttered to himself. "Wonder if I can persuade him
+to go?"
+
+As the car which had brought Mr. Hodgman on his hasty trip from
+Washington dashed up to the front of the house, Grace Duvall, looking
+very charming in a blue linen dress, was just approaching it from the
+rear.
+
+She held a pair of shears in her hand, and her apron was filled to
+overflowing with hundred-leaf roses. "Dick--oh, Dick!" she called, as
+she came down the long avenue of syringas and lilacs which led to the
+house. "The sweet peas are nearly ready to bloom."
+
+Richard Duvall, looking as simply pastoral as though he had never
+tracked an international crook to cover, raised his head from the
+flower bed, in which he had been carefully setting out circle after
+circle of geranium plants.
+
+"Are they?" he laughed. "That's good. Now all we need is a few good hot
+days." He gathered up his trowel and rake, and started toward the barn.
+
+Grace put her arm through her husband's and together they strolled
+across the springy green turf, their faces smiling and happy. The
+honeymoon showed no signs of waning.
+
+This lovely old country place, in southern Maryland, had been one of
+Richard Duvall's dreams for many years, and after his marriage to Grace
+Ellicott, in Paris, it had become hers, as well. It was but a short time
+after their return to America that they decided to make it a reality.
+
+Grace had encouraged her husband in the plan of giving up, for a time at
+least, his warfare against crime, his pursuit of criminals of the higher
+and more dangerous type, and had persuaded him to buy the farm which had
+once belonged to his mother's people, and settle down to the life of a
+country gentleman.
+
+His office was still maintained, under the able direction of one of his
+assistants, but Duvall gave little or no attention to its affairs. He
+was glad to withdraw, for the first time in over nine years, from
+active work, and devote his energies to early potatoes, prize dogs,
+hunters, and geranium plants--and, above all, to the peaceful enjoyment
+of his honeymoon, and the making of Grace the happiest woman in the
+world.
+
+She, on her part, found in their present situation all the joys of
+existence for which she had longed. With little or no liking for the
+monotonous round of society and its duties, and a passionate love of
+nature, she found in the many and complex duties of managing her part of
+their extensive estate a far greater happiness than any which city life
+could have offered her.
+
+The considerable fortune which her husband's clever work while in Paris
+had restored to her, had been safely invested in well paying securities,
+and she found her greatest joy in utilizing at least a part of her
+income in beautifying their new home.
+
+Richard had steadily refused to make any use of the money. It was a
+matter of pride with him, that his own savings had enabled him to
+purchase the property; but when Grace proposed to build an addition to
+the house, to provide him with a more comfortable library and work room,
+or insisted upon having the roads throughout the place elaborately
+macadamized, he was obliged to submit to her wishes. In this way, they
+planned and built for the future, together.
+
+The farm was a large one, comprising some two hundred acres, and the old
+stone house surrounded by white oaks and tulip poplars had once been a
+show place, before the declining fortunes of its former owners had
+caused it to fall into a state of mellow and time-honored decay. Now all
+was changed. Grace, with the able assistance of old Uncle Abe Turner, a
+relic of ante bellum times, spent hours daily in bringing order out of
+the chaos of tangled myrtle and ivy, overgrown box and hedge, thickets
+of syringa and lilac bushes and weed-grown lawns.
+
+It was a gigantic task, yet a joyous one--as it ever is, to those who
+came to it with the love of nature in their hearts. To Grace, the plants
+and shrubs, the great strong oaks, the towering poplars, each seemed to
+have a distinct personality. Under her energetic hand, the place once
+more took on the aspect of well kept and orderly beauty which was such a
+contrast to its former down-at-the-heels appearance. It seemed as though
+the growing things realized the personal interest she took in them, and
+responded as they never respond to the ignorant or unsympathetic.
+
+Richard was concerned with his fields of timothy and clover, his early
+corn, his berries and fruit trees, to say nothing of his collies, his
+prize cows and Kentucky horses. In such a life, time never hangs
+heavy--he was busy studying, planning, working, from morning to night,
+and his active mind soon convinced his capable overseer and the farm
+hands as well that, although Richard Duvall was by no means a
+professional farmer, he could still show them a thing or two when it
+came to the rotation of crops, the spraying of fruit trees, or the
+proper treatment of worn out soils. These were aspects of farming life
+which the hide-bound conservatism of the local farmers caused them to
+jeer at, as newfangled notions gotten from books. Later when they saw
+the man who farmed with his head as well as his hands gather in two
+bushels where they had barely been able to secure one, they began to sit
+up and take notice.
+
+"I got the new hedges all set out today," Grace went on, as she patted
+her husband's rather grimy hand. "They will be charming, against the
+gray stone of the wall. But we must have new gate posts. The old ones
+are likely to tumble into the road at any moment."
+
+"I'll have Martin come out tomorrow and look them over. There's plenty
+of stone--down in the lower pasture. Why not carry the wall right along
+the whole front of the property? It ought not to cost a great deal."
+
+"We will. And I'm going to have a new spring house built, too. The old
+one is falling to pieces." She looked up at her husband as he deposited
+the rake in the tool room and they started up the shaded walk toward the
+house. "Aren't you glad, Dick, that we're _alive_?"
+
+He pressed her arm. "Well--I should say so, little girl! Why do you ask
+me that?"
+
+"Oh--you know what your friends all said--that a man might as well be
+dead, as buried out here in the country. I think they are the ones who
+are not alive--cooped up in the city. Don't you?"
+
+Richard nodded. He was thinking for the moment of his former active
+life--when some battle of wits with a noted crook had kept him sleepless
+for nights. "It's--rather different," he laughed. "Isn't it?"
+
+"Yes--and much better. Don't you think so, dear? You wouldn't want to go
+back to it--would you?"
+
+"Not for anything in the world," he assured her, as he swept the newly
+seeded lawns with a contented glance. "I liked the other life, of
+course--the excitement, the danger of it; but this is better--much
+better. Here, Don!" he called to a graceful collie which was barking
+vociferously at some distant vehicle in the road. "Come here and be
+quiet." He turned with Grace to the great vine-covered side porch and
+sank contentedly into a rocking chair. "Well, little girl--it's been a
+busy day, and I'm tired. We got the early rye all cut on the lower field
+today. Guess we'll put in late potatoes, after it's plowed. Here,
+Don--come back here! What's the matter with you?" He rose and whistled
+to the dog, which was bounding across the lawn in the direction of the
+road. "Come back, I say!"
+
+"It's someone coming in," said Grace, uneasily. "In a machine. I wonder
+who it can be?"
+
+"Possibly Hudson, the veterinary. He was coming today, to look at that
+heifer."
+
+"He hasn't a machine like that. This is a big touring car." She turned
+to her husband. "Hadn't you better go in and fix up a bit, Dick? It may
+be company."
+
+Duvall laughed. "If it is, they'll have to take me as I am," he said;
+then again called to the dog.
+
+A moment later the servant, who had interviewed the caller at the front
+door, came out to the side porch. "Gentleman to see you, Mr. Duvall,"
+she said. "Seems to be in a powerful hurry, too."
+
+"All right, Aunt Lucy," said Duvall as he made his way to the front of
+the house.
+
+"Is this Richard Duvall?" the visitor asked, in a quick, almost
+peremptory tone, as the detective joined him.
+
+"Yes. That is my name. What can I do for you?"
+
+The newcomer rose nervously from his chair and began chewing upon his
+half-smoked cigar. "Had the devil of a time to find you, Mr. Duvall."
+
+"You came out from Washington, I suppose," remarked the detective,
+wondering what his visitor could want with him.
+
+"Yes. Got your address from Hicks, of the Treasury Department. He said
+you were about twelve miles out. I seem to have come about twenty."
+
+"Perhaps you went around by way of Laurel. It's much further, that way.
+What can I do for you, Mr.----" He paused interrogatively.
+
+The man looked up at him quickly. "My name's Hodgman--Thomas Hodgman--of
+New York. I represent John Stapleton."
+
+"John Stapleton, the banker?" asked Duvall, surprised.
+
+"Yes. You know him, don't you?"
+
+"Yes. Quite well. I handled a case for him once--some years ago. Why?"
+Duvall's face became grave. He began to realize that the interview was
+likely to become suddenly important. John Stapleton, the
+multi-millionaire banker, was not in the habit of sending messengers to
+anyone, without good reason.
+
+"So he said," went on Mr. Hodgman, resuming his chair. "That's why I'm
+here. He wants you to take another--"
+
+"Another?"
+
+"Yes. Another case. Quick."
+
+"It's quite out of the question."
+
+"Nonsense! This is important. Money's no object; name your own terms."
+
+"It isn't a question of terms, Mr. Hodgman. I have withdrawn, for the
+time being at least, from active professional work."
+
+"I know." The visitor flicked the ashes impatiently from his cigar and
+sought nervously in his pockets for a match. "That's what they told me
+at your office, in New York. Said you were on your honeymoon, and didn't
+want to be bothered."
+
+"That's true. I don't."
+
+"I told Mr. Stapleton that. He sent me to see you; said you might change
+your mind, when you heard about the case."
+
+"It is quite impossible. I do not care to take up any detective work at
+present."
+
+Mr. Hodgman fidgeted nervously in his chair. "You must listen to what I
+have to say, Mr. Duvall, at any rate. Mr. Stapleton would not hear to my
+returning, after seeing you, without having explained to you the nature
+of the case."
+
+Duvall leaned back, and began to fondle the long moist nose of the
+collie which sat beside his chair. "If you insist, Mr. Hodgman, I will
+listen, of course; but I assure you it will be quite useless."
+
+"I hope not. The case is most distressing. Mr. Stapleton's only child
+has been kidnapped!"
+
+"Kidnapped!" Duvall sat up with a start, every line of his face tense
+with professional interest. "When? Where?"
+
+"In Paris. The cablegram arrived this morning. I don't know the details.
+Mrs. Stapleton has been spending the winter abroad. Mr. Stapleton was to
+join her this month. She is living at their house in the Avenue Kleber,
+Paris. The child was out walking with a nurse. It has been stolen.
+That's all I know."
+
+"When did it happen?"
+
+"Yesterday morning. Mrs. Stapleton did not cable at first, believing
+that the boy would be found during the course of the day. Naturally she
+did not wish to alarm her husband needlessly, and the Prefect of Police,
+it seems, had assured her that the child would undoubtedly be recovered
+before night. It wasn't. This morning Mr. Stapleton got a long cablegram
+from his wife, telling him of the boy's disappearance. He's half crazy
+over the thing."
+
+"What is he going to do?"
+
+"I don't know. He sent me to see you at once. I'm his secretary, you
+know. When I couldn't find you in New York, he told me to come here. I
+arrived in Washington an hour ago, and came right out. Mr. Stapleton
+said if any man on earth could find his boy for him, you could."
+
+"I suppose the thing is a matter of blackmail--ransom--"
+
+"Very likely. They will probably demand a huge sum. No requests have
+been made, as yet, so far as I know. These fellows usually wait a week
+or two, before showing their hand, to give the unfortunate parents a
+chance to worry themselves half to death. I suppose they figure that
+then they'll be more likely to come across with the money."
+
+"Yes. That's the scheme. A rotten business, too. Hanging is too good for
+such wretches!"
+
+"That's what I say. Of course you can understand how Mr. Stapleton
+feels."
+
+"Of course. He will sail at once, I suppose."
+
+"That's the worst of it. He can't go till Saturday. Tomorrow's
+Thursday--that's three days off. There's a deal on here involving
+millions--something he's been working to put through for months. Of
+course he doesn't consider anything like that, when it comes to his
+child; but he's got to think of his associates--men who have intrusted
+their money to him. He can't possibly sail before Saturday. He wants you
+to go ahead of him. There's a fast boat leaving in the morning. You
+could take that. We can have a conference tonight. It will mean mighty
+quick work, though." He glanced at his watch. "After six now. There's no
+train till midnight--the sleeper. But Mr. Stapleton told me to charter a
+special. We can be in New York by one o'clock in the morning, if we
+start right now." He looked at Duvall in eager expectancy.
+
+The latter frowned, his gaze wandering off to the distant fields, where
+the newly plowed earth reminded him of his plans for the morrow. Yet
+here was a man, a friend, who had helped him much, in the earlier days
+of his career, begging him to come to his assistance in a matter almost
+of life or death. It was a difficult decision that he was called upon to
+make. The thought of leaving Grace hurt him deeply; yet she would prefer
+to stay behind, in case he should go, to look after the affairs of the
+place. With the assistance of the overseer and the hands, he knew that
+she could manage everything during a brief absence on his part--it
+seemed unlikely that the matter would require more than three or four
+weeks, at the outside.
+
+Mr. Hodgman broke in upon his thoughts. "You'll go, Mr. Duvall? Mr.
+Stapleton is depending on you. He has the utmost faith in your
+abilities. He knows your familiarity with Paris--the work you have done
+there, in the past. He believes that, by intrusting the matter to a
+fellow countryman, he will get his boy back again. He hasn't much faith
+in foreign detectives. He's set his heart on having you start for Paris
+at once. I can't go back and tell him that you have refused." Mr.
+Hodgman spoke in a loud and earnest voice, due to his very evident
+excitement. Neither he nor Duvall noticed that Grace had approached
+them, and was standing in the open doorway of the house.
+
+Before the detective had an opportunity to reply, Grace spoke. "What is
+it, Richard?" she inquired, quietly.
+
+Duvall rose, presented Mr. Hodgman to his wife, and bade her sit down.
+Then, in a few words, he acquainted her with the circumstances which led
+to the latter's visit.
+
+"Think of that poor mother, alone there in Paris," Hodgman supplemented.
+"Think of her suffering, her anxiety. I realize how much we are asking,
+to take Mr. Duvall away from you, especially at this time; but, it is
+Mr. Stapleton's only child--a boy of six. You can understand how he must
+feel."
+
+Grace nodded. "Yes, I can understand," she said, slowly, then turned to
+her husband.
+
+"What do you think, dear?" he asked her.
+
+"I think, Richard, that you had better go."
+
+Mr. Hodgman sprang to his feet, and, coming over to Grace, took her
+hand. He knew that his battle was won. "I thank you, Mrs. Duvall," he
+said, "on Mr. Stapleton's account, as well as on my own. He will
+appreciate deeply what you have done, the sacrifice you are making, and
+he will not forget it." He looked again at his watch nervously, the
+anxiety he felt clearly evident in his every movement. "We had best
+start at once, Mr. Duvall."
+
+Duvall rose. "I will join you in a short while, Mr. Hodgman. I wish to
+say a few words to my wife." He took Grace's arm and drew her within the
+house, leaving Mr. Hodgman pacing nervously up and down the veranda.
+
+The conference between Grace and her husband was short. Each realized
+the distress which tore at the other's heart, as well as the dangers he
+would in all probability be called upon to face; yet they met the
+situation calmly. "You will not be gone long," she told him. "I can
+manage very well."
+
+"I know you can, dear," he said, pressing her to him. "I'm not worried
+about the place. You can run that as well as I can. It's you, I'm
+worried about--leaving you"--
+
+"I'll be all right," she assured him, in spite of her tears. "I have
+Aunt Lucy, and old Uncle Abe, and Rose, and Jennie. I won't be so _very_
+lonely. And you will be very careful--and--and come back soon--won't
+you?"
+
+"Of course, dear. Very soon. Now I'd better get a few things together."
+
+Fifteen minutes later Grace Duvall stood on the steps of the veranda,
+watching the flying automobile as it rapidly became a little red blur in
+the distant road. It was nearly dark. The frogs in the patch of marsh in
+the meadow were piping dismally. She shivered, and a great sense of
+desolation came over her. She sank into a chair and wept, while Don,
+inserting his long white muzzle between her hands, strove to lick away
+her tears.
+
+She heard Aunt Lucy, the old negro cook, singing away at her work in the
+kitchen, accompanied by Uncle Abe, who occupied a bench on the back
+porch. Everything seemed strangely peaceful, and lonely, too, now that
+Richard had gone. She patted the eager head of the collie. "We'll have
+to make the best of it, Don," she said, and rose to enter the house.
+
+Suddenly far down the road she heard the chugging of an automobile. They
+were not frequent visitors, upon this country road. Could it be Richard,
+she wondered, returning for something he had forgotten?
+
+She stood, straining her eyes into the dusk, waiting, while with one
+hand she restrained the eager dog.
+
+Presently she saw that the machine was not a red one. It was not
+Richard. She was about to enter the house, when she realized that the
+rapidly moving car had entered the grounds. She turned on the lights in
+the hallway and stood, waiting, the dog at her side bristling with
+anger.
+
+In a moment the automobile had stopped, and almost before she realized
+it, a small, foreign-looking man stood on the doorstep before her.
+"Madame Duvall?" he inquired, quickly, in a voice which showed plainly
+his nationality.
+
+"Yes," she replied.
+
+"Your husband! May I see him?"
+
+"He is not at home."
+
+The newcomer seemed greatly disturbed. "Then I fear, Madame, that I
+shall be obliged to wait until he returns."
+
+"He will not return. He has gone away for sometime."
+
+"Ah! That is indeed a calamity!" The man's face showed the keenest
+disappointment. "May I ask where I can find him?"
+
+"It will be quite impossible." Grace had no intention of telling her
+visitor where her husband had gone. She knew too well the intricacies of
+his profession, for that. "You cannot find him." She made as though to
+close the door, and thereby terminate the interview.
+
+The newcomer realized her intention. Slowly he raised his hand, in the
+palm of which showed the seal of a ring, turned inward. It was of
+silver, with curious figures worked into it in gold. The man glanced
+from the ring to Grace, eying her steadily. "I think, Madame," he said,
+with a meaning smile, "that you can trust me."
+
+Grace recognized the ring at once. It was similar to one she herself had
+worn, while engaged in the memorable search for the ivory snuff box for
+Monsieur Lefevre, Prefect of Police of Paris. Dear old Lefevre--the
+friend of Richard's, and of her own! This man who stood before her must
+be a messenger from him.
+
+"Come in, please," she said, quietly, and led the way to the library.
+
+The man followed her, calling out a few words to his chauffeur as he did
+so. No sooner had they reached the great book-lined room, than he drew
+from his pocket a sealed envelope.
+
+"Madame Duvall," he said, earnestly, "Monsieur Lefevre has cabled to his
+representatives in Washington a message. That message is contained in
+this envelope. I have instructions to deliver it to your husband
+immediately. In case I could not find him, I am to hand it to you.
+Permit, me, Madame." With a bow, he placed the message in her hand.
+
+Grace took the envelope, broke the heavy seal which it bore, and drawing
+out a slip of paper, hastily read the contents. The message was from
+Monsieur Lefevre. It said:
+
+ My dear Duvall:
+
+ You promised, on the occasion of our last meeting, to come to me
+ should I ever need you. I need you badly, my friend. Come at once,
+ both you, and your dear wife. LEFEVRE.
+
+Grace looked up at the man before her, the letter crumpled in her hand.
+Here was a message the urgency of which could not be denied. She knew
+that, had Richard been at home, he would have gone to Paris at once in
+response to it; for it was to Monsieur Lefevre that they in reality owed
+all their happiness. She recalled vividly their wedding, with the
+lovable old Frenchman, acting as her father for the occasion, giving
+away the bride. She remembered the farewell dinner at the Prefect's
+house, and the beautiful gift he had given her on that occasion.
+Evidently Monsieur Lefevre desired Richard's presence very greatly, and
+her own as well. The thought suddenly came to her--why not go to him?
+
+True, Richard had left her in charge of things at home; but she knew
+that, for a reasonable time, at least, they would go on smoothly enough
+without her. Hendricks, the overseer, was a capable and honest man,
+devoted to her and to her husband.
+
+She could safely leave matters in his charge. Then, too, the thought of
+surprising Richard on the steamer sailing the next day appealed to her
+sense of mischief. How astounded he would be, to find her strolling
+along the deck! And how delighted, too! She wondered that the thought of
+accompanying him had not occurred to her more strongly before. She
+turned to the man, who stood watching her narrowly.
+
+"You know the contents of this message?"
+
+"Yes, Madame," he bowed. "It came to us by cable--in cipher."
+
+"There is a train for New York at midnight, and a steamer tomorrow
+morning."
+
+"Yes, Madame."
+
+"Can you drive me to Washington in your car?"
+
+"I shall be delighted, Madame." The fellow's eyes sparkled with
+satisfaction.
+
+"Very well. Mr. Duvall is in New York. I will take the message to him.
+Wait here, please, until I get some clothes together and give some
+orders to my servants."
+
+In half an hour, the thing was done. Hendricks, the overseer, had been
+given full instructions regarding taking charge of the place, with
+provision for his needs in the way of money, etc., and by ten o'clock,
+at which time the New York sleeper was open, Grace was at the station,
+purchasing her ticket.
+
+The obliging Frenchman gave her every assistance, and bade her _bon
+voyage_ smilingly as he helped her aboard the train. She retired at
+once, and lay in her berth, reading a magazine, and picturing to herself
+Richard's mingled astonishment and joy at their meeting in the morning.
+This time, she was determined that their honeymoon should not be
+interrupted.
+
+After a time, she fell asleep, and dreamed that she and Richard were
+sailing gaily toward Paris, in a large red touring car.
+
+In the morning, she ate a hasty breakfast in the railway station, and
+took a taxicab for the steamship offices. By great good fortune, she was
+able to secure a cabin. Then she hastily visited a banking house where
+she was well known, provided herself with funds, and drove to the dock.
+
+It wanted but half an hour till sailing time. Grace hastened to her
+stateroom, and busied herself in effacing the stains of her night of
+travel. She was determined to meet Richard looking her best.
+
+It was not until the big steamer was passing through the Narrows that
+she came on deck, and began looking about for her husband. In all that
+crowd, she knew it would take time to find him. After searching for an
+hour, she felt somewhat surprised at not seeing him. After another hour
+had passed, her surprise turned to alarm. A hasty visit to the purser,
+and an examination of the sailing list, showed her the astonishing
+truth. Richard was not on board!
+
+
+
+
+CHAPTER II
+
+
+Richard Duvall arrived in New York at half past one o'clock Thursday
+morning. Hodgman, Mr. Stapleton's secretary, had wired ahead the news of
+their coming, and the banker's limousine awaited them at the railway
+station. Fifteen minutes later they were ascending the steps of Mr.
+Stapleton's residence on Fifth Avenue.
+
+Duvall had not been to the house before. His previous interviews with
+the banker had taken place at the latter's office, in Broad Street. He
+had no time now, however, to observe the luxury of his surroundings. Mr.
+Hodgman hurried him at once to the library, and in a few moments Mr.
+Stapleton had joined them.
+
+He greeted Duvall with a nervous handshake, and thanked him for his
+prompt coming. He was clearly laboring under an intense mental strain.
+
+"Mr. Hodgman has explained my reasons for sending for you, Mr. Duvall?"
+he inquired, sinking into a great leather-covered chair.
+
+"Yes." Duvall nodded.
+
+"Then you can appreciate my feelings." He sat in silence for several
+moments, looking gloomily at the floor.
+
+"Perfectly."
+
+"The devils! I wouldn't care if they were to steal my property--money,
+securities, anything like that. I can fight them--on that basis. But my
+child! Don't you see why your coming was of the utmost importance to me?
+I don't dare move against these rascals openly. If I do, they will
+threaten to retaliate by injuring my boy, and I am powerless. Whatever I
+do, must be done secretly. No one must know that you are in my employ.
+No one must know your object in going to Paris. You see that?"
+
+"Most certainly. These fellows cannot hold you responsible for any moves
+the police authorities of Paris may make; over them you of course have
+no control. But if you make any efforts on your own account, any
+independent efforts, to recover your boy, they must by all means be made
+in secret."
+
+"Exactly. You understand, then, what you are to do?"
+
+"Yes. But first I must ask you, Mr. Stapleton, to give me some account
+of the affair. Mr. Hodgman has told me only that your son has been
+kidnapped. No doubt you have learned by this time how the thing was
+done."
+
+"What I have learned, Mr. Duvall, convinces me of the importance of
+being on the ground at once. The affair, as cabled to me by my wife, is
+preposterous--absurd!" He again gazed at the floor in gloomy
+preoccupation.
+
+"How so?" the detective inquired.
+
+"I will tell you. My boy, who, as you know, is six years old, has been
+in the habit of driving, each morning, accompanied by his nurse, from my
+house in the Avenue Kleber, to the Bois de Boulogne. On arriving in the
+Bois, it has been their habit to leave the automobile in which they
+came, and spend an hour or more walking and playing on the grass. I have
+insisted on this, because the boy needs exercise, and he cannot get it
+driving about in a motor car."
+
+"During this hour what becomes of the car?" asked Duvall.
+
+"Our orders have been, of course, for the chauffeur to wait, within
+sight and call. I believe he has done so."
+
+"Thank you. Go ahead."
+
+"On Wednesday the nurse took Jack--the boy's name is Jack--to the Bois
+as usual. She played about with him on the grass for probably an hour.
+Then she sat down to rest. Jack was standing near her, playing with a
+rubber ball. She says--and, gentlemen, my wife cables me that she
+solemnly swears to the truth of her statements--that she turned away for
+a moment to observe passing vehicles in the road--turned back again to
+the child--and found that he was gone."
+
+"Gone--but how?"
+
+"How? That's the question. Here is this woman, sitting on the grass,
+with the child, a hundred yards from the road, in the middle of a large
+field of grass--a lawn. No one is within sight. The nearest person, it
+appears from her testimony, is the chauffeur, three hundred feet away,
+in the road. The woman turns her head for a moment, looks about--and the
+boy is gone. That is the story she tells, and which my wife has cabled
+to me. Do you wonder that I call it preposterous?"
+
+"Hardly," remarked Duvall, with a grim smile. "The boy could not have
+vanished into thin air. The woman must be lying."
+
+"That, Mr. Duvall, is what I cannot understand. I cannot believe that
+the woman is lying. My wife cannot believe it. She has been in our
+employ ever since the boy was born, and is devoted to him. Mrs.
+Stapleton cables that she is completely prostrated."
+
+"But, Mr. Stapleton, you can hardly believe such a story! How could the
+child have been stolen, if her story is true? It is, as you say,
+preposterous."
+
+"I do not say that the story is true, Mr. Duvall. I say that I do not
+think that Mary is lying. She is telling what she believes to be the
+truth. She turned her head for a moment--the boy was gone. That is what
+she says, and I believe her. The question is--how is it possible?"
+
+"It isn't," Hodgman grunted.
+
+"Everything is possible, Hodgman," said the banker, reprovingly. "The
+best proof of that, in this case, is that it has happened. What means
+were used, I cannot imagine; but the apparently impossible _has_
+happened. The boy is gone!"
+
+"Is the nurse a young woman?" the detective inquired.
+
+"About thirty, I should say."
+
+"An American?"
+
+"Yes. Of Irish parentage. Her name is Lanahan--Mary Lanahan."
+
+"A New Yorker?"
+
+"She comes from Paterson, New Jersey. Her people live there."
+
+"Are there any other details--any other points of interest?"
+
+"None, so far as I know. What I have told you, is what has been cabled
+to me by Mrs. Stapleton. She is naturally in a more or less hysterical
+condition. Nothing can be accomplished here. I want you to leave by
+today's steamer. I myself, I regret to say, cannot go until Saturday."
+He passed his hand nervously across his forehead. "Only matters of the
+most vital importance could keep me here at such a time, Mr. Duvall;
+but, unfortunately, such matters confront me now."
+
+"Have you any reason to believe, Mr. Stapleton," Duvall inquired, "that
+the kidnapping is the act of persons from this side of the water? Have
+any such attempts been made in the past?"
+
+Mr. Stapleton remained silent for sometime, buried in thought. Presently
+he spoke. "I am a rich man, Mr. Duvall--a very rich man. Men in my
+position are constantly in receipt of letters of a threatening nature. I
+have received many such letters, in the past."
+
+"Was the matter of the child mentioned in any of them? Were threats made
+involving him?"
+
+"There was one such letter."
+
+"When did you receive it?"
+
+"Last fall--perhaps six months ago."
+
+"Have you the letter now?"
+
+"Yes."
+
+"May I see it?"
+
+The banker rose, went to a heavy rosewood desk at one side of the room,
+drew open one of its drawers, and removed a steel despatch box. He
+opened it with a slender key and took out a package of letters. From
+these, after some hesitation, he selected one and silently handed it to
+Duvall.
+
+The detective examined the letter carefully. It was enclosed in a cheap
+white envelope, such as are sold at all post offices, having the stamp
+printed on it. The letter itself was roughly printed in ink on a sheet
+of ruled paper evidently torn from an ordinary five-cent pad. It said:
+
+ "We demand fifty thousand dollars, to be placed in thousand-dollar
+ bills inside a cigar box and expressed to John Smith, c/o Express
+ Company, Paterson, N. J., next Monday afternoon. The man who will
+ call for the package on Tuesday will know nothing about the matter,
+ and if you arrest him, you will find out nothing. Keep this to
+ yourself and do as we say, if you value the safety of your child."
+
+There was no signature to the letter. Duvall read it through with great
+care, then turned to Mr. Stapleton.
+
+"You have observed, I suppose, that the place to which the money was to
+be sent, Paterson, New Jersey, is the home of your child's nurse, Mary
+Lanahan."
+
+Mr. Stapleton started. "I confess," he said "that, in the agitated state
+of mind into which this affair has thrown me, I had completely
+overlooked the coincidence. What do you infer from it?"
+
+"Only this, Mr. Stapleton, that Mary Lanahan may know more about this
+matter than she is willing to let on. I must keep this letter for the
+present."
+
+"Very well." The banker nodded. "It may prove a valuable clue."
+
+"Possibly. And further, Mr. Stapleton, I shall not sail by today's
+steamer."
+
+"But--why not?" Stapleton sat up in his chair in surprise. "You will
+lose two days."
+
+"I do not think they will be lost. I must make some investigations in
+Paterson, before I leave here. Please give me, if you can, the address
+of Mary Lanahan's parents."
+
+Mr. Stapleton frowned. "I am not sure that I can do so, Mr. Duvall. My
+wife has charge of these matters. But I recollect having heard that her
+father, Patrick Lanahan, is a florist in a small way, and no doubt you
+can readily locate him. But I fear you will be losing valuable time."
+
+Duvall rose. "I feel, as you do, Mr. Stapleton, that I should be in
+Paris at the earliest possible moment; but I think you will agree with
+me that some investigations on this side before I go are absolutely
+necessary, and may prove of inestimable value afterwards."
+
+Mr. Stapleton was silent for several minutes. Presently he raised his
+head. "Under the circumstances, Mr. Duvall, I am forced to admit the
+truth of what you say. Conduct your investigations as quickly as
+possible, however; for we must positively sail by Saturday's boat."
+
+"I shall be ready then." Duvall took up his hat. "Now I think I had
+better get a few hours' sleep, and in the morning I will make an early
+start for Paterson." He bowed to the banker and Mr. Hodgman. "Good
+night, gentlemen. I shall see you both on Saturday morning. The steamer
+sails shortly after noon, I believe. Suppose I come here at ten o'clock,
+and let you know what I have learned?"
+
+Mr. Stapleton rose. "If I receive any further news of importance from
+Paris, Mr. Duvall, I will advise you at your hotel. Where are you
+stopping?"
+
+Duvall gave the name of a Times Square hotel at which he usually
+stopped, and with a quick "good night" left the house.
+
+It was shortly after nine o'clock the next morning when he descended
+from the train at Paterson, and going to a nearby drug store, consulted
+the directory for the address of Patrick Lanahan. He found it without
+difficulty, and, by means of an electric car, was soon before the
+florist's door.
+
+The place was situated on the outskirts of the town, and consisted of a
+small, rather mean-looking cottage, from which spread out on each side,
+like the two wings of an aëroplane, the long glass greenhouses.
+
+A little gate opened to a short brick path, leading to the front door of
+the house.
+
+Duvall went up the path and rang the door bell. A wholesome-looking
+Irish woman, of perhaps fifty, opened the door, and, in response to his
+questions, told him that her husband, Patrick, was out in the garden at
+the rear of the house, busy with his plants.
+
+She directed the detective along a narrow areaway at the side of the
+house, and in a moment reappeared at the back door.
+
+"Pat," she called. "Oh, Pat! Here's a gentleman to see you."
+
+A short, heavy-set man, with gray hair and mustache and a ruddy and
+weatherbeaten face, arose from among a litter of flower pots and bulbs.
+
+"What can I do for you, sir?" he asked, coming forward and wiping his
+hands upon his overalls.
+
+The detective studied the man before him intently. The honest and
+clear-looking eyes told him nothing that was not favorable.
+
+"I came to ask you a few questions, Mr. Lanahan."
+
+"Questions, is it? About what?" The blue eyes showed a sudden flare of
+suspicion.
+
+"About yourself, and your family."
+
+"Who may you be, then? Is it the tax man?"
+
+Duvall smiled. "Not the tax man," he said. "I represent a firm of
+lawyers in Washington. My name is Johnson."
+
+Lanahan, still suspicious, pointed to a couple of kitchen chairs that
+stood on the brick-paved yard beneath a trellis covered with hop vines.
+"Sit down, sir. I'll have a smoke, if you don't mind." He began to fill
+his short clay pipe. "What would lawyers in Washington be wantin' with
+me?"
+
+"That is what I wish to find out, Mr. Lanahan. We--my firm--have been
+advised that a certain Michael Lanahan, of Dublin, recently died,
+leaving a large estate. We are trying to find his heirs. Tell me
+something about yourself and your family."
+
+The look of suspicion and reserve which the old man had up to this time
+shown faded from his face, and was replaced by a smile of incredulity.
+"Money, is it?" he laughed. "Mary--that's my wife--has been seein'
+bubbles in her tay for the week past. What is it you would know?"
+
+"Are you from Dublin?"
+
+"Me father was. I was born right here in Jersey, meself."
+
+"What was his name?"
+
+"Patrick, the same as me own. But he had a brother, Mike."
+
+"Ah. It may be the same." Duvall pretended a sudden interest. "His
+business?"
+
+"Mike's? Faith--I never heard he had any, lest it was drinkin' all the
+good liquor he could lay his hands on."
+
+Duvall pretended to make a series of entries in his notebook. "Now
+about yourself, Mr. Lanahan. Have you any children? Of course, should
+there be any money coming to you, they would share in it."
+
+"Children, is it? I have two."
+
+"Boys?"
+
+"One is a boy--a man be now, I should say. He's in the city--workin'.
+His name is Barney."
+
+"What does he do?"
+
+Lanahan looked up with a quick frown. "The last I heard tell, he was
+tendin' bar, Mr. Johnson--over at Callahan's saloon, on the Bowery. He's
+wild--wild--like me uncle Mike, I should say."
+
+"And the other?"
+
+The old man's face took on a contented look. "The other is me daughter
+Mary, bless her. She's nurse in the family of old man Stapleton, the
+millionaire."
+
+Duvall closed his book. "I see," he remarked, pleasantly. "She's not
+married, I suppose?"
+
+"Mary? Divil a bit! For a time, she was sweet on a French chuffer that
+worked for Mr. Stapleton; but the fellow's gone, now, and she's clane
+forgot him. That was near a year ago."
+
+"Ah, yes. Do you happen to remember his name?"
+
+"Alphonse, it was--Alphonse Valentin, or some such joke of a name. A
+comic valentine he was, too, with his dinky little mustache and his
+cigarettes." He laughed loudly. "Imagine my Mary, married to a gink like
+that!"
+
+Duvall replaced his notebook in his pocket and rose. "I'm mightily
+obliged to you, Mr. Lanahan. We will advise you at once, if our
+investigations show that you are related to the Michael Lanahan whose
+fortune is in our hands. I'm obliged to you for your courtesy."
+
+The florist nodded. "You're welcome, sir. I guess them Lanahan's must be
+a different breed. I never heard tell of any of my people makin' any
+fortune. Good day, sir." He turned to his work, chuckling.
+
+Duvall rode back to the station, and took the first train for New York.
+It was clear that Mary Lanahan's parents had nothing in common with
+blackmailers and kidnappers. Their honesty was as evident as the
+blueness of their eyes, or the redness of their hair. But the
+information about Alphonse Valentin, the chauffeur, and Barney, Mr.
+Lanahan's son, seemed more promising.
+
+It was close to one o'clock when Duvall arrived at Callahan's saloon, on
+the Bowery, near Canal Street. Here a disappointment awaited him. Barney
+Lanahan had thrown up his job and left two months before. Callahan had
+no idea where he had gone. He had not been about the place since. A
+negro porter volunteered the information that he had seen the man
+entering the Broadway saloon of an ex-prizefighter some weeks before;
+but, beyond that, Duvall could learn nothing.
+
+After a hasty luncheon he went to his office on Union Square, where his
+unexpected appearance caused his assistants unlimited surprise. He
+directed them to locate Barney Lanahan at the earliest possible moment.
+He then called up Mr. Stapleton's secretary, Mr. Hodgman, and inquired
+about the chauffeur.
+
+Mr. Hodgman informed him that the banker had employed Valentin in Paris
+some eighteen months previous, and had brought him to this country,
+where he had remained in his employ for about six months. He had been
+discharged, through some dishonesty in the matter of purchasing
+supplies, and nothing further had been seen or heard of him.
+
+Duvall, on receiving this information, proceeded at once to the office
+of the French line, and asked permission to inspect their passenger
+lists for the past year. He concluded that if Valentin had anything to
+do with the kidnapping of Mr. Stapleton's boy, he was, in all
+probability, in Paris, and, if so, would almost certainly have crossed
+by this line. He was therefore not at all surprised to find the name of
+Alphonse Valentin among those sailing during the preceding March.
+
+There was little more that he could accomplish, now, beyond writing a
+long letter to Grace, whom he naturally supposed to be patiently
+awaiting his return in the country. He had a short interview with Mr.
+Hodgman in the evening, and was lucky enough to secure a photograph of
+Alphonse Valentin, the chauffeur, taken at the steering wheel of his
+machine. The car had, it seemed, been photographed, along with a party
+of guests, by a friend of Mr. Stapleton's with a leaning toward amateur
+photography. Duvall placed the photograph among his belongings with a
+smile of satisfaction. He felt that his delay had been by no means
+unprofitable.
+
+One other step he took, before leaving. Accompanied by Mr. Hodgman, he
+made a careful inspection of the room which had been occupied by the
+nurse, Mary Lanahan, at the Stapleton house. The results were
+distressingly meager. All the woman's belongings she had evidently taken
+with her, on going abroad. There appeared to be nothing which would
+afford the slightest clue to her character or habits.
+
+Mr. Hodgman turned to the door with an impatient frown. "Nothing here,"
+he growled, and was about to leave the room.
+
+"Nothing much," said Duvall, glancing carelessly at the wooden edge of
+the bureau. "This woman, Mary Lanahan, is evidently an up-to-date sort
+of person."
+
+Hodgman paused. "Why do you say that?" he asked.
+
+"Smokes cigarettes, I see."
+
+"That so. How do you know?"
+
+Duvall smiled. "Too simple even to mention, Mr. Hodgman. See those burns
+on the varnish?" He pointed to a number of spots along the edge of the
+dresser. "Always find them somewhere about, where there's a cigarette
+smoker." He gazed out of the window for a moment. "Rooms tell a great
+deal about the personality of the people who have occupied them. For
+instance, I've never seen this Lanahan girl, but I know that she's not
+over five feet four, that she has light hair, that she reads in bed,
+that she writes with a stub pen, and that she's a Roman Catholic.
+Furthermore, she is left handed, inclined to be vain, wears her hair in
+waves, or curls, in front, is fond of the theater, and has a long narrow
+scar on the palm of her left hand."
+
+He chuckled quietly, as he saw Mr. Hodgman's look of amazement. "All
+very simple--quite elementary, in fact. I won't even bother to tell you
+how I know--just little things here and there about the room. Here's one
+of them," he said, as he picked up a rusty pen point from the desk.
+"That shows she uses a stub, of course; but the way the point is worn
+also proves that she's left handed. And here's another." He pointed to
+the electric bulb which hung over the head of the bed. "Nobody would use
+that light, except to read by in bed. The others in the room are more
+than sufficient for purposes of illumination. Yet the lamp has been used
+continuously, as its condition shows. See how blackened the glass
+is--and notice also how the white enamel of the back of the bed is worn
+off, just under the lamp. That's from propping a pillow against it,
+night after night." He turned toward the door. "Of course, those things
+aren't of any value, probably, in this case; but I can't help noticing
+them. Force of habit, I suppose."
+
+When Duvall arrived at the Stapleton house on Saturday morning, he found
+the banker somewhat disturbed by a cablegram he had just received. "Mary
+claims attempts made to poison her. Will recover. Come at once," it
+read.
+
+The detective appeared to be somewhat astonished, on reading the
+cablegram. "Looks as though somebody was afraid she might be going to
+talk," he remarked. "The sooner we arrive in Paris, now, the better."
+
+
+
+
+CHAPTER III
+
+
+Grace Duvall's first inclination, on finding herself en route for
+Europe, without her husband, was to send him a wireless, advising him of
+her movements. Then she decided, for several reasons, not to do so.
+Chief among these was the fear that such a startling piece of news would
+be likely to cause him a great deal of unnecessary anxiety. She knew
+that she could never hope to explain matters, within the limits of a
+marconigram. And then, too, it was highly inadvisable, she knew, to
+mention in a wireless message the real reason which had caused her to
+leave home.
+
+So she decided to make the best of the matter, realizing that within a
+few days, she would see Richard in Paris, and explain everything to his
+satisfaction.
+
+Immediately on reaching Paris, she drove to the office of the Prefect of
+Police, and sent in her card to Monsieur Lefevre. She thought it
+possible that he would expect her, as his agent in Washington would no
+doubt have communicated with him. Nor was she mistaken.
+
+He rushed into the anteroom as soon as he received her card, and
+embraced her with true Gallic fervor, kissing her on both cheeks until
+she blushed. Then he drew her into his private office.
+
+"Where is your husband?" he asked, eagerly, as soon as Grace was seated.
+
+"I--I do not know. Probably on his way to Paris."
+
+"But--my dear child! Did he not then come with you?"
+
+"No. He--he had other business."
+
+"Other business! But I understood that he had temporarily retired." The
+Prefect seemed greatly astonished.
+
+"So he had; but an old friend, Mr. Stapleton"--
+
+Lefevre did not allow her to finish. "Stapleton!" he fairly shouted. "He
+is employed by him? Mon Dieu!"
+
+"Why not?" asked Grace in surprise.
+
+"But--it was for that very case that I desired his assistance. And by
+this Stapleton, who cables that the whole police force of Paris are a
+lot of jumping jacks! Sacré! It is insufferable!"
+
+"You wanted my husband for the same case?"
+
+"Assuredly! What else? The child of this pig of a millionaire is
+stolen--what you call--kidnapped! We have been unable to find the
+slightest clue. I am in despair. My men assure me that it is the work of
+an American gang. I conceive the hope that Monsieur Duvall may know
+these men--that he may be in possession of information that will lead to
+their capture. This rich American, he has spoken with contempt of the
+Paris police. The efficiency of my office is questioned. My honor is at
+stake. I send for my friend Duvall, to assist me, and--sacré!--I find
+him already working for this man who has insulted me. It is monstrous!"
+
+Grace could scarcely repress a smile. How excessively French the Prefect
+was, after all. "My husband did not know, when he agreed to take the
+case for Mr. Stapleton, that you wanted him. He does not know it now. He
+has not yet received your message."
+
+"Then he does not know that you are in Paris?"
+
+"No. I thought he would be crossing on the same boat. When I found that
+he wasn't, my first thought was to send him a wireless. Then I realized
+that I couldn't do so, without saying something about the business that
+had called me to Paris--without, in fact, mentioning you. I feared to do
+this--for there are so many people nowadays tapping the wireless. I
+thought it better to keep the matter a secret."
+
+"And you did quite right. I wanted your husband to take up this case,
+quite independently, and without it being known to anyone that he was in
+my employ." He paused for a moment in deep thought. "No doubt his
+employment by Mr. Stapleton is to be kept equally secret."
+
+"I suppose so. He asked me not to say anything about it. I had to tell
+you, to explain matters."
+
+"And he doesn't know that you are in Paris?" The Prefect gave a sudden
+laugh. "_Ma foi!_--what a joke!"
+
+"A joke?"
+
+"Assuredly! Don't you see? I am going to ask _you_ to take up this case,
+yourself. I must use every means to recover the child of this Stapleton,
+before others do so for him. My professional pride will not permit me to
+be beaten. If I can't have your husband, at least I shall have you."
+
+"But--I shall be working in opposition to him."
+
+"Not in opposition. You will both have the same object in view--the
+recovery of Mr. Stapleton's boy. Whichever of you does so first, the
+result will be the same--the boy will be restored to his parents. But I
+want you, my child, to be the one to do this."
+
+"But, Monsieur Lefevre, I could not hope to accomplish anything--where
+trained men have failed."
+
+"Who knows? I remember well the assistance you gave us, in the matter of
+the ivory snuff box. Without your help, we should never have recovered
+it. I have faith in a woman's intuition. You will find this child for
+me, and give your husband the surprise of his life."
+
+"But," said Grace, smiling mischievously at the prospect which opened
+before her, "suppose he should see me?"
+
+"You must disguise yourself somewhat. Change the color of your hair; it
+is easily done--here in Paris." The Prefect laughed. "A slight
+alteration in appearance only will be necessary. And do not recognize
+your husband, should you meet him face to face. That is most important."
+
+"Why?"
+
+"Because, should he become convinced that it is really you, I fear he
+would insist upon your dropping the case entirely, and that would not
+suit my plans at all. Come, my child." The Prefect's eyes twinkled with
+amusement. "Do this thing for me. It will be a little joke, between us.
+The honeymoon detectives, I called you, once. What an amusing thing,
+that now you should be working in competition with each other, on the
+same case!" He began to laugh heartily.
+
+"Well," said Grace, her sense of mischief getting the better of her,
+"now that I'm here, I suppose I might as well keep busy. Richard won't
+be here for two days, and I may find out something in that time."
+
+"Excellent!" The Prefect clapped his hand smartly upon his knee. "You
+have two days' start. In two days, much may be accomplished. Come, let
+us go over the case in detail."
+
+An hour later, Grace left the Prefect's office in a taxicab, having
+arranged to have her baggage sent to Monsieur Lefevre's house, where she
+was to stay while in Paris. Her previous acquaintance with Madame
+Lefevre made this an ideal arrangement. She was to pose as a friend, in
+Paris on a visit.
+
+She ordered the driver of the taxicab to take her to Mr. Stapleton's
+house in the Avenue Kleber.
+
+She found Mrs. Stapleton to be a very pretty and stylish woman of
+thirty; whose beauty, however, was sadly marred by the intense suffering
+through which she was passing. The poor creature had scarcely slept for
+over a week, and her distress was pitiable.
+
+She answered Grace's questions as well as she could, under the
+circumstances. There was, after all, little to say. The nurse, it
+appeared, stuck to her story--that the boy had vanished, in the
+twinkling of an eye, while her back had been turned for but a few
+moments. Mrs. Stapleton could offer no explanation--attempted none.
+
+"It is all so mysterious--so terrible!" she cried. "Poor Mary--she is
+too ill to see you, I fear, or I would have her tell you the story
+herself."
+
+"Too ill?" inquired Grace, who had come more to question the maid, than
+Mrs. Stapleton. "What is the matter with her?"
+
+"They tried to poison her--last Friday."
+
+"They? Who?"
+
+"I do not know. She went out for a walk. The poor woman was half dead,
+from nervous exhaustion and loss of sleep. She tells me that she stopped
+to get a cup of chocolate at a café in the Rue St. Honoré. After that
+she came back to the Champs Élysées, and sat upon a bench. She began
+suddenly to feel deathly ill, and, calling a cab, was driven home. When
+she arrived here, she was unconscious, and had to be carried to her room
+by the servants. She has been in bed ever since. I am glad to say,
+however, that she is better, and I think she could see you, by morning."
+
+Grace left the Stapleton house, feeling somewhat baffled. The more she
+heard of this curious affair, the more inexplicable it seemed. She had
+hoped to visit the scene of the kidnapping, in company with the nurse,
+and examine the spot with her own eyes. This she now realized she could
+not do until the following day. She was walking in the direction of the
+Arc de Triomphe, revolving the affair in her mind, when a young man,
+evidently a Frenchman, of good appearance and not unpleasant face, came
+up beside her, bowed politely, and in excellent English asked her
+regarding Mary Lanahan.
+
+"Miss Lanahan--is she better?" he inquired.
+
+"Who are you, monsieur?" asked Grace, suppressing her inclination to
+resent the man's action, in her hope that she might learn something from
+him of value. His question showed Grace at once that he was acquainted
+with at least one member of the Stapleton household.
+
+"I am a friend of Miss Lanahan's," the man replied. "I hear that she is
+ill. I saw you enter and leave the house, and I ventured to ask you if
+she is better."
+
+"I was told that she is. I did not see her."
+
+A peculiar expression crossed the young man's face; but Grace could not
+determine, so fleeting was it, whether it indicated pleasure or
+disappointment.
+
+They walked along in silence for a few moments, and had almost reached
+the arch, when a ragged little urchin, a veritable Paris gamin, came up
+to Grace's companion and thrust a crumpled bit of paper into his hand,
+then darted off, whistling shrilly.
+
+The man looked after him a moment, then examined the note. Whatever its
+contents, they made a startling impression upon him. He looked about, an
+expression of fear upon his face, turned to Grace with a hurried bow,
+and a quick good evening, and at once walked off in the opposite
+direction at full speed, at the same time fumbling in the breast pocket
+of his coat, as though searching for something in it. In his efforts, he
+dropped several papers to the street. Grace watched him as he picked
+them hurriedly up and moved off into the gathering darkness.
+
+She fancied that one of the bits of paper had escaped his notice, and,
+on going back to the spot, found that she was correct. A small visiting
+card lay upon the sidewalk. She picked it up, and read the name as she
+walked away. It was Alphonse Valentin, Boulevard St. Michel.
+
+Grace slipped the card into her pocketbook. The man's name meant nothing
+to her--she fancied that he was some friend of Miss Lanahan's, concerned
+about her condition. Yet why did he not inquire for her at the house, in
+the ordinary way? And why should the note, handed to him by the street
+urchin, have caused him such evident alarm?
+
+She glanced at her watch, and saw that it was close to seven o'clock.
+She had intended to return to Monsieur Lefevre's for dinner; but a
+sudden determination to find out more about this man Valentin caused her
+to proceed at once to a hotel near the Louvre, where she ate her dinner
+alone.
+
+An hour later she descended from a cab at the number on the Boulevard
+St. Michel, which was inscribed upon Alphonse Valentin's card.
+
+The place was a dingy old building, the main floor of which was occupied
+by a dealer in cheese. A narrow doorway at one side gave access to the
+upper floors. Grace rang the bell, and waited in some trepidation. This
+going about Paris at night was rather an unusual experience. She thought
+of the simple joys of her life at home, and for a moment regretted that
+she had not stayed there. The opening of the door interrupted her
+thoughts.
+
+The woman who stood in the hallway regarded her without particular
+interest, and inquired her business. "I wish to see Monsieur Valentin,"
+said Grace.
+
+"He is not in."
+
+"Then I will wait. I must see him. He expects me."
+
+The woman shrugged her shoulders. "As you wish, mademoiselle. Come this
+way." She led Grace up a flight of stairs, and indicated a door at the
+rear of the upper hall. "That is Monsieur Valentin's room." Then she
+turned away, apparently quite indifferent as to whether Grace entered or
+not.
+
+The latter placed her hand on the knob of the door, and slowly pushed it
+open. The room was dark; but the light from the rear windows rendered
+the objects within it faintly visible. Upon the table stood a lamp. With
+some difficulty the girl succeeded in finding a match, and lit it.
+
+The light of the lamp disclosed a rather large room, with a small
+alcove in the rear, containing a bed. The alcove was curtained off from
+the main room. Grace, however, did not spend much time in examining her
+surroundings. A photograph on the table at once attracted her
+attention--not because it represented anyone she knew, but because,
+across the bottom of it, was inscribed, in a feminine hand, "Mary
+Lanahan."
+
+She had just completed her examination of the photograph, when two other
+objects attracted her attention. One was a crumpled bit of paper, upon
+which a few words were scrawled in lead-pencil. They were, "I am
+suspicious of François. Watch him." The note was unsigned.
+
+The third object upon the table which caught Grace's attention was a box
+of cigarettes, open, and nearly full. They were small gold-tipped
+affairs, of the kind generally used by women, and it was this
+peculiarity that at first attracted her attention. She thought it
+strange, that a man should use such cigarettes. She looked at the box,
+and observed that they were of American make.
+
+Illustration: Once inside he made without hesitation for the table,
+picked up the box of cigarettes and thrust it into his pocket.
+
+Idly she took up one of the cigarettes, and held it in her fingers. She
+read the name of the brand, printed upon the paper wrapper, and was
+about to drop it back into the box, when she heard a curious rasping
+noise outside one of the rear windows. It sounded as though someone were
+climbing the wall of the house. Instinctively she shrank back and
+concealed herself behind one of the curtains which hung before the
+alcove door.
+
+The rasping and scraping continued for some little time, and presently
+Grace, peering through the space between the curtains, saw a face appear
+at one of the windows. It was a determined face, heavily bearded, dark,
+evil looking. Its gleaming eyes swept the room with cautious care, then,
+evidently satisfied that it was unoccupied, their owner began
+noiselessly to raise the sash of the window.
+
+It was slow work. Several minutes passed before the man succeeded in
+raising the sash sufficiently to permit him to crawl into the room. Once
+inside, he made without hesitation for the table, glanced over its
+contents, picked up the box of cigarettes and thrust it into his pocket,
+and then, without paying the least attention to anything else, walked
+quickly to the door of the room and passed out into the hall.
+
+The girl waited for a moment, then stepped into the light. As she did
+so, she realized that she held in her hand one of the gold-tipped
+cigarettes she had taken from the box. She quickly thrust it into her
+pocketbook, and, with sudden decision, left the room and descended the
+stairs. She had an instinctive feeling that the man who had stolen the
+cigarettes was in some way connected with the kidnapping of the
+Stapleton child. She determined to follow him, leaving the interview
+with Alphonse Valentin to another time.
+
+She left the house, and saw the man going down the Boulevard some fifty
+feet in advance of her. She walked along after him, pretending to be
+totally uninterested in her surroundings, while at the same time keeping
+a sharp watch upon him.
+
+He seemed in somewhat of a hurry, and walked briskly along, looking
+neither to left nor to right. Grace kept as close to him as she dared,
+without running the risk of detection. The walk was a long one. When
+half an hour had passed, the girl saw that they were entering the Champs
+Élysées. The Seine they had long since crossed by the Pont Neuf. Up the
+brilliantly lighted avenue they went, toward Arc de Triomphe. At the
+corner of the Avenue Kleber, the man turned to the left. Grace followed,
+wondering where the chase would lead next. To her astonishment, the man
+disappeared suddenly through a gate which formed the servants' entrance
+of one of the stately houses which fronted on the avenue. She looked up.
+It was the house of Mr. Stapleton!
+
+
+
+
+CHAPTER IV
+
+
+On the day following that upon which she arrived in Paris, Grace Duvall
+sallied forth, determined to find out two things--first, the position
+occupied by Alphonse Valentin in the affair of the kidnapping; secondly,
+the identity of the man who had stolen the box of cigarettes from
+Valentin's room, and gone with them to the house in the Avenue Kleber.
+The latter incident seemed trivial enough, at first sight; yet she
+reasoned that no one would risk arrest on the score of burglary, to
+steal anything of such trifling value, without an excellent reason.
+
+She had a short conference with Monsieur Lefevre, before she left the
+house, and told him of the events of the previous night. The Prefect
+seemed greatly interested.
+
+"Could you identify the man who stole the cigarettes?" he asked.
+
+"Easily. I had a splendid view of his face."
+
+"Then go to Mr. Stapleton's house and take a look at all the servants.
+You may find him among them."
+
+"I had intended to do so, this morning."
+
+The Prefect smiled. "I do not know what your investigations will lead
+to, but they seem promising. I have a dozen men working on the case; yet
+so far they have not made the least progress. Their efforts, however,
+are directed toward finding the child. They are searching the city with
+the utmost care. We believe that by discovering the missing boy, we
+shall also find the persons who committed the crime."
+
+"Have you no one under suspicion?"
+
+"No one. The nurse, Mary Lanahan, is of course being closely watched;
+also the chauffeur, François. My men report, however, that he gave them
+the slip for an hour, last night. I have an idea that he may prove to be
+the one who took the cigarettes."
+
+"Can you imagine any reason for his having done so?"
+
+"I confess, my child, that I cannot. It seems utterly absurd; unless,
+indeed, there was something else concealed in the box."
+
+"What?"
+
+The Prefect laughed. "I cannot imagine. But if you can identify the
+man, we shall no doubt find out. As for the matter of Alphonse Valentin,
+we have already had him under observation. So far as we can learn, he is
+merely a chauffeur, out of work, who seems to be somewhat in love with
+the nurse."
+
+"Then his actions have not been suspicious, during the past week?"
+
+"Not in the least. He has hung around the Stapleton house for several
+days, asking for news of the Lanahan woman; but that is all. We
+attribute his actions to a natural anxiety over her illness."
+
+Grace left the house, by no means satisfied with the progress she was
+making. Her interview with Mary Lanahan, and subsequent visit to the
+scene of the crime, told her nothing she had not already known. Her
+greatest disappointment, however, came when she had Mrs. Stapleton bring
+in François, ostensibly to question him about his part in the affair.
+She saw at once that he was not the man who had broken into Alphonse
+Valentin's room on the night before. This man had been heavily bearded
+and tall. François was smooth shaved and rather short. Mrs. Stapleton
+assured her that none of her servants resembled in the least her
+description of the burglar. She left the house, greatly dissatisfied,
+after satisfying herself that this was the case.
+
+Her visit to the house of Alphonse Valentin that afternoon was
+productive of no greater results. The man was out. The woman who opened
+the door--the same one who had admitted her the previous
+evening--regarded her with ill-concealed suspicion, and informed her
+that she had no idea when her lodger would return. Grace left,
+determined to try again the following day.
+
+Throughout the whole evening she hung about the Stapleton house, hoping
+again to see the man with the heavy beard who had disappeared within the
+night before; but he did not put in an appearance. Grace began to feel
+discouraged. She thought of her lilac bushes, at home, of Aunt Lucy
+feeding the chickens, of the dogs, the sweet call of the wood robins
+among the poplar trees on the lawn, and half wished that she had stayed
+at home and left to Richard the apparently hopeless task of finding the
+abductors of little Jack Stapleton.
+
+What, after all, could she hope to do, where the entire police force of
+Paris had failed? The thing was absurd. Monsieur Lefevre had overrated
+her abilities. She heard the sound of church bells, striking the hour of
+ten, and decided to go home and forget the whole affair until tomorrow.
+Tomorrow--the day Richard must arrive! How she longed to be with him!
+This stupid interruption of their honeymoon seemed peculiarly cruel, now
+that over a week had elapsed since they had seen each other. She
+wondered if she would meet him, the next day. Then she thought of her
+changed appearance, of her hair, dyed a jet black, and worn in a new and
+to her mind unbecoming fashion, of her darkened complexion, her
+extremely French costume, her heavy veil, and laughed. If Richard did
+see her, here in Paris, when he fully believed her to be peacefully
+tending her flower beds at home, he would never believe the evidence of
+his senses.
+
+She was strolling toward the Champs Élysées, lost in thought, when
+suddenly she heard the soft throbbing of a high-powered motor car, as it
+came up the street behind her. She turned and glanced toward it; but the
+brilliant glare of the electric headlights blinded her. She could see
+nothing, except that the car was moving very slowly.
+
+Suddenly it stopped, almost abreast of her, and a tall man leaped to the
+sidewalk. Before she had an opportunity so much as to glance in his
+direction, he came swiftly up behind her, threw his arm about her neck,
+and choked her into unconsciousness. Her last sensation was of being
+lifted bodily into the already moving car, and then the feeling of rapid
+motion, quickly blotted out by the coming of insensibility.
+
+When she returned to consciousness, it was broad daylight. She lay upon
+a small wooden bed, in a low-ceilinged little room, the only furniture
+of which was a small chest of drawers and a chair. Upon this chair sat a
+large man, his face so thoroughly hidden by a mask that his features
+were quite unrecognizable. He was regarding her with keen scrutiny.
+
+"Oh--what--where am I?" she gasped.
+
+The man hesitated for a moment, then slowly spoke. "Where you are,
+mademoiselle, is of no importance. Attend to what I have to say."
+
+Grace made no reply. There seemed nothing that she could say. She sat up
+and gazed at the man, half dazed. Her head swam. She felt that she had
+been drugged.
+
+"Ten days ago," the man went on, in a cold and menacing voice, "the
+child of Monsieur Stapleton was taken from his nurse in the Bois de
+Boulogne. You are trying to find that child."
+
+"But--" Grace made a movement of protest.
+
+"It is useless to deny it. You have been watched."
+
+Grace gasped in silence.
+
+"I desire to send a message to the boy's father, and I have chosen you
+to take it to him. I have selected you, because to send one of my own
+men would doubtless result in his arrest. That is why you have been
+brought here."
+
+"The--the child is safe?" asked Grace.
+
+"Perfectly. You shall see for yourself." He motioned to the window.
+
+Grace rose, and looked out. The view comprised a bit of garden,
+surrounded by bushes. She could see nothing beyond--nothing that would
+enable her in any way to identify the place. On the tiny plat of grass
+in the garden sat a child--a little girl, playing with a small black and
+white spaniel. Her dark hair was drawn tightly beneath a pink sunbonnet.
+Her dress, her whole appearance, was that of a peasant child.
+
+Grace turned from the window, bewildered. "I see nothing," she said,
+"except a little girl--"
+
+"That is the child of Monsieur Stapleton," the man said. "Now attend to
+the message."
+
+She sat down again, wondering.
+
+"Tell the boy's father this: He will leave his house tomorrow evening,
+in his automobile, at eight o'clock. He will bring with him, in a
+package, the sum of five hundred thousand francs--one hundred thousand
+dollars. He will have with him, in the automobile, no one but himself
+and his chauffeur. He will leave Paris by the Porte de Versailles, and
+drive along the road to Versailles at a speed of twelve miles an hour.
+Somewhere upon that road, among the many automobiles that will pass him,
+will be one, from which a blue light will flash, as it approaches him.
+It will also slow up. He will toss the package of bank notes into that
+car, and drive on. If the package contains the sum of five hundred
+thousand francs, he will find his child at his house, upon his return.
+If not, or if these instructions are not carried out to the letter--if
+there is any attempt made at pursuit--the child will not be there, and
+you can tell him that he will be given but one more chance. After that,
+the boy will die."
+
+The man in the mask made this gruesome statement with the utmost
+coolness.
+
+Grace listened, aghast at the cruelty of his words, and at the same time
+struck by the extreme ingenuity of the plan. To catch the perpetrators
+of the crime, under these circumstances, seemed impossible. A rapidly
+moving automobile--one of a hundred. An instant's flash of a blue light
+in passing--the tossing into the car of the money--and it would speed
+away into the darkness, beyond any hope of detection. Should Mr.
+Stapleton have others in his car--should he have his car followed by a
+second, containing armed men, the occupants of the kidnapper's machine
+would no doubt refuse to give the signal, and nothing would be
+accomplished. It would be impracticable to line the road, for a possible
+distance of twenty miles, with gendarmes, nor could their presence
+accomplish anything, beyond putting the kidnappers on guard, and
+preventing the carrying out of the plan.
+
+The weakest point in the whole scheme seemed, to Grace at least, the
+delivery of the child to Mr. Stapleton, provided he paid the money
+demanded. Just how that was to be accomplished, without subjecting the
+person who brought the boy to arrest, she did not see. A moment's
+reflection, however, showed her that a stranger might be employed, at
+any point, who for a few francs would agree to take the child to the
+house. She turned to the man before her with feelings not devoid of
+admiration.
+
+"How can Mr. Stapleton know that you will do as you say?"
+
+The man shrugged his shoulders. "That is a chance he must take. If he
+does not believe that the child will be delivered to him, provided he
+pays the money, he had better not pay it. But if he does his part, I
+shall do mine--and this I swear by the memory of my mother!"
+
+Grace shuddered. A wretch of this sort, talking about the memory of his
+mother! "Very well," she said quietly, "I will take your message."
+
+"Good! You will not leave here, of course, until it is dark--tonight.
+You will be blindfolded, and conducted to some point in the city. From
+there, you can make your way to Monsieur Stapleton's house." He rose,
+and went toward the door. "Make no attempt to escape. It will be
+useless. Any attempts on the part of the police to interfere with the
+plan I have outlined will result in nothing. Food will be sent in to you
+at once. Good morning."
+
+It was close to ten o'clock that night, as nearly as Grace could judge,
+when she was led a considerable distance blindfolded, to a closed
+automobile, and driven away. She could form no idea of her whereabouts.
+The car continued on its way, for over an hour. Once she attempted to
+snatch the bandage from her eyes; but a hand was placed upon her arm by
+another occupant of the machine, and a low voice warned her to desist.
+
+After an interminable ride, the car suddenly stopped, and she felt the
+man at her side slip away from her and open the door. Instantly she
+snatched the bandage from her eyes. The man had disappeared. She stepped
+to the sidewalk, and looked about. She was standing upon a brightly
+lighted street, which seemed somehow familiar to her. The man on the box
+of the cab glanced down at her with a look of curious interest. She saw
+his face clearly, in the light of the street. It was the heavily bearded
+man whom she had seen take the box of cigarettes from the room of
+Alphonse Valentin two nights before.
+
+Grace stood with the bandage which had encircled her eyes, still in one
+hand. Suddenly she saw a dark figure uncoil itself from the rear of the
+car, and drop noiselessly to the pavement as the machine started off.
+She gave a low cry of surprise. The man came up to her, a grim smile
+upon his face. It was Alphonse Valentin.
+
+
+
+
+CHAPTER V
+
+
+John Stapleton, the millionaire banker, accompanied by Richard Duvall,
+arrived in Paris early in the afternoon, and went at once to the
+former's house in the Avenue Kleber.
+
+Upon their arrival, Duvall waited for sometime, while the distressed
+husband and wife were closeted together upstairs. At last they descended
+to the library, and Duvall was presented to Mrs. Stapleton.
+
+The joy which her husband's arrival had caused her sent a new glow of
+hope to her careworn cheeks, and she greeted the detective most
+cordially. Clearly she felt that now something would at last be done, to
+find her missing child.
+
+Duvall's first questions related to Mary Lanahan, the nurse. He was
+relieved to find that she had quite recovered from her sudden illness.
+
+"Will you kindly have her brought here, Mrs. Stapleton?" he asked. "I
+would like to question her."
+
+In a few moments the nurse appeared. She was an extremely good-looking
+girl, smart and well dressed. Duvall recognized in her frank face, her
+clear blue eyes, the same appearance of honesty which had impressed him
+during his interview with Patrick Lanahan, her father.
+
+"Mary," said Mrs. Stapleton, "this is Mr. Duvall. He is trying to find
+Jack for us. Tell him your story."
+
+The girl turned to Duvall, who had risen. "I can hardly expect you to
+believe what I am going to say, Mr. Duvall, yet I assure you that it is
+the solemn truth."
+
+"Go ahead, Miss Lanahan," said the detective. "I am prepared to believe
+whatever you may say."
+
+The girl sat down, at Mrs. Stapleton's request. She still was somewhat
+weak, from her recent illness.
+
+"It was a week ago last Wednesday. I left the house with Master Jack at
+half-past ten, and we drove to the Bois."
+
+"Just a moment, please." Duvall stopped her with a quick gesture. "How
+long had you been going to the Bois in this way?"
+
+"Over six weeks."
+
+"And you always left about the same time--half-past ten?"
+
+"Always."
+
+"Who accompanied you besides the child?"
+
+"François--the chauffeur."
+
+"Always?"
+
+"Yes."
+
+Duvall turned to Mrs. Stapleton. "How long has this man François been in
+your employ?"
+
+"A year--in June."
+
+"You have found him honest, reliable?"
+
+"Always. Otherwise I should not have kept him."
+
+The detective turned to Mary Lanahan. "Go ahead, please," he said.
+
+"We reached the Bois shortly before eleven--François had orders to go
+slowly, when Master Jack was in the machine--and drove about for fifteen
+minutes. Then we stopped at the place where we were in the habit of
+playing."
+
+"Was it always the same place?"
+
+"Yes. There is a smooth field of grass there, and a clump of trees by
+the road, where the machine always waited."
+
+"Go on."
+
+"We left the car, and walked out over the grass. Master Jack had a big
+rubber ball, and he was kicking it along, and running after it.
+Sometimes he would kick it to me, and I would throw it back to him. We
+played about in that way for over half an hour. Mrs. Stapleton wished
+the boy to have the exercise."
+
+"I see. And you generally played about in the same place?"
+
+"Yes."
+
+"How far from the road?"
+
+"About three hundred feet."
+
+"And from the nearest bushes, or woods?"
+
+"A little more than that, I should say."
+
+"You could see François, in the machine, from where you were?"
+
+"Yes, I could see the machine. I could not always see François; for
+sometimes he would get out, and walk about, or sit under the trees and
+smoke a cigarette."
+
+"Do you remember noticing him, on this particular morning?"
+
+"Yes. I saw him sitting in the machine."
+
+"What was he doing?"
+
+"Reading a newspaper."
+
+"Had he ever done that before?"
+
+The girl hesitated, as though a new idea had come to her. "No--I cannot
+remember that he ever had."
+
+"Very well. Go ahead with your story."
+
+"Well--after we had played for about half an hour--I got tired and sat
+down on the grass. Master Jack still kept playing about with the ball. I
+sat idly, looking at the sky, the road--dreaming--"
+
+"About what?" interrupted the detective, suddenly.
+
+The girl colored. "About--about some people I know."
+
+"Go ahead."
+
+"I heard the boy playing, behind me. Then I looked around--and--he was
+gone!" The nurse made this statement in a voice so full of awe that it
+carried conviction to her hearers. Duvall felt that, whatever the real
+facts of the disappearance of the child, this woman's story was true.
+
+"What did you do then?"
+
+"I stood up and looked about. I thought Master Jack was hiding from
+me--playing a joke on me. Then I realized that there was no place that
+he could hide. The nearest trees were too far off. He could not have
+reached them. I called and called. I was very much frightened."
+
+"François, who heard me, came running over the grass. I asked him if he
+had seen Master Jack. He said, no, that he had not seen anyone. After
+that we searched everywhere--in the woods, along the road--for nearly an
+hour, but could find nothing. Then we came home, and told Mrs.
+Stapleton." The girl looked at her employers in fright.
+
+"What about the rubber ball?" Duvall asked, suddenly.
+
+"It--it was gone."
+
+"Then it is clear that the child must have been taken away peaceably,
+without objection on his part. Had he struggled, cried, he would have
+dropped the ball, would he not?"
+
+"I suppose so."
+
+"How long was your head turned from him--while you were--dreaming?"
+
+"About a minute."
+
+"Not more?"
+
+"No."
+
+"How do you estimate the time so closely?"
+
+"I'm sure it could not have been longer. A minute is quite a long
+time."
+
+"What time was it when you got back to the house?"
+
+"About--about one o'clock, I think." The girl turned to Mrs. Stapleton
+for confirmation of her answer.
+
+"It was a quarter-past one," said Mrs. Stapleton, promptly. "I noted the
+time particularly, because it was later than usual. Mary had orders to
+bring Jack back for luncheon not later than one."
+
+Duvall began to make some figures on a piece of paper. "You fix the time
+of the boy's disappearance at 11.30. You say you hunted for him an hour.
+That would be 12.30." He looked at the girl searchingly. "You arrived
+home at 1.15. That would mean that it took 45 minutes to get here." He
+turned to Stapleton. "Please send for your chauffeur, François."
+
+Mr. Stapleton rang a bell, and ordered the servant who responded to send
+in the chauffeur. Meanwhile Mary Lanahan was regarding Duvall with
+nervous apprehension.
+
+"We must have hunted for him longer than I thought," she said, at
+length.
+
+Duvall made no reply, but waited until the arrival of the chauffeur. He
+proved to be a short, heavily built man, with long powerful arms, and a
+swarthy face--evidently from the south of France. His countenance was
+stolid and emotionless. He appeared the well trained servant.
+
+Duvall addressed him at once. "How long would it take you, my man,
+driving fast, to reach this house from the spot in the Bois where Master
+Jack was lost?"
+
+The man responded at once. "Ten minutes," he said, "easily."
+
+"What time was it when this woman," the detective indicated the nurse,
+"called to you, on discovering that the child was gone?"
+
+"I do not know."
+
+"Have you no idea?"
+
+"It must have been about twelve o'clock. We hunted for the boy till
+about one--then came home."
+
+"The nurse says it was half-past eleven."
+
+The man shrugged his shoulders. "It may have been. I did not observe the
+time."
+
+"What were you doing?"
+
+"I was asleep."
+
+Mr. Stapleton started. "Asleep?" he demanded, angrily.
+
+The man nodded. "The day was warm. I had nothing to do. For a time I
+read the paper. I must have dozed in my seat; for, the next thing I
+knew, the nurse was calling to me, and the boy was gone."
+
+Duvall frowned. "Then you could not say whether anyone else was near the
+nurse and the boy, at the time he was kidnapped?"
+
+"No, monsieur. I could not."
+
+"That will do." The detective turned to Mr. Stapleton. "Have your man
+drive us to the place where all this occurred."
+
+The banker gave the man the order, and he left the room. Then Duvall
+turned again to Mary Lanahan.
+
+"You were taken suddenly ill one day last week. Tell us about it."
+
+The woman looked up. "It was very mysterious, sir. I went out for a
+walk. At a café in the Rue St. Honoré I had a cup of chocolate."
+
+"Alone?" asked the detective, sharply.
+
+The woman colored. "No," she faltered. "I--I was with a friend."
+
+"Who?"
+
+"A--a gentleman I know." She glanced fearfully at Mr. Stapleton. "I--I
+would rather not give his name."
+
+"Was it Alphonse Valentin?" asked Duvall, quickly.
+
+The woman colored still more deeply. "Yes," she replied, in scarcely
+audible tones.
+
+The banker regarded her in surprise. "Alphonse Valentin!" he cried. "The
+fellow I discharged last year, for dishonesty? Mr. Duvall--he's your
+man!"
+
+"No--no!" exclaimed the nurse, excitedly. "He knows nothing of the
+matter--nothing!"
+
+"That remains to be seen," remarked Duvall, slowly. "Where did you meet
+this fellow, Valentin?"
+
+"At the café in the Rue St. Honoré."
+
+"You had met him there frequently before?"
+
+"Yes."
+
+"After you left the café, what did you do?"
+
+"We walked to the Champs Élysées and sat on a bench, talking. Suddenly I
+felt very ill. Mr. Valentin called a cab and sent me home."
+
+"Give me the address of this café, please."
+
+The woman did so. As Duvall was entering it in his notebook, a servant
+announced that the automobile was at the door.
+
+In fifteen minutes the party, consisting of Mr. Stapleton, Duvall, and
+Mary Lanahan, were leaving the car at the spot in the Bois de Boulogne
+which had been the scene of the kidnapping. François was ordered to
+drive his machine to the exact spot, as nearly as he could tell, that it
+had occupied on the previous occasion. Mary Lanahan led the others to
+the place on the grass where she had sat.
+
+It was evident at once that the distances she had named in telling her
+story were less, if anything, than the actual facts. It was quite
+impossible to see how, in any way, the child could have been taken from
+the spot she indicated, to the woods, without consuming a considerable
+period of time--five minutes, at least. To believe that the nurse could
+have turned away her head for a moment, and then looked around to find
+the boy gone seemed the sheerest fabric of the imagination; yet the
+woman, in repeating her story, stuck to it with a grim pertinacity
+which, it seemed, could come only from the knowledge that she was
+telling the truth.
+
+Ten days had elapsed since the boy had been kidnapped. It seemed almost
+useless to search the spot for any evidences of the crime. Yet Duvall
+began to go over the ground where the nurse testified that she had sat,
+with the most minute care. Inch by inch, he examined the turf,
+subjecting almost every blade of grass to a separate examination. The
+operation required over half an hour, and both Mr. Stapleton and the
+nurse grew tired of watching him, and strolled about aimlessly.
+
+Hence they did not see him pick up a tiny object from the grass. It was
+a half-smoked cigarette, dirty and almost falling to pieces from the
+action of the weather, yet held together by a slender tip of gold.
+
+He placed it carefully within his pocketbook, and rose. "Nothing more to
+be done here," he called to Mr. Stapleton, and in a moment the three
+were proceeding toward the waiting automobile.
+
+Upon the return to the house, Mr. Stapleton drew the detective into his
+library. "Have you discovered anything, Mr. Duvall?" he inquired, making
+an effort to conceal his almost frantic anxiety.
+
+"I do not know--yet. I may have a clue; but I am not sure."
+
+"What do you think of the woman's story?"
+
+"It seems impossible to believe it."
+
+"You think, then, that she had a hand in the matter--she and this fellow
+Valentin?"
+
+"It begins to look like it."
+
+"On what do you base your conclusions, Mr. Duvall? I cannot bring myself
+to believe that Mary Lanahan is lying, ready as I am to suspect this
+fellow Valentin."
+
+"First, Mr. Stapleton, on the facts themselves. The boy could not have
+been taken away without her knowledge. Secondly, upon some minor
+matters--her error of half an hour, in telling her story, for instance."
+
+"I am sorry, Mr. Duvall, but I cannot believe that you are right. I'd
+suspect Valentin, at once; but if Mary Lanahan is not telling the truth,
+then my experience of twenty years in judging human nature has been
+wasted."
+
+"Yet you yourself heard her admit that she was with Valentin only last
+Friday, the day she was taken ill."
+
+"Yes. That is true." Mr. Stapleton passed his hand uncertainly across
+his forehead. "It's too much for me."
+
+"Let me have a word with the nurse, alone, before I go," asked Duvall.
+
+"Certainly," replied the banker. "I'll send her in to you."
+
+When Mary Lanahan entered the room, the detective went up to her and
+eyed her sternly. "Was Alphonse Valentin with you at any time, in the
+Bois, that day?"
+
+"No," replied the girl, steadily.
+
+"Does he smoke gold-tipped cigarettes?" asked Duvall, suddenly.
+
+The effect of this question upon the nurse was startling. She recoiled
+as though the detective had struck her. "He--he does not smoke at all,"
+she gasped, her face gray with fear.
+
+"Don't lie to me!"
+
+"He does not smoke at all," repeated the girl, almost mechanically, and
+stood confronting him with a defiant air.
+
+"Very well. That is all." The detective turned from the room and left
+the house.
+
+He did not, however, go very far. It was rapidly becoming dark. He
+passed down the street until he judged he was out of sight of the house,
+then slowly retraced his steps upon the other side, until he had reached
+a point nearly opposite the small iron gateway which served as the
+servants' entrance to Mr. Stapleton's house. Here, hidden behind a
+tree, he watched for perhaps half an hour.
+
+At the expiration of this period, he was rewarded by seeing a young man,
+evidently an under servant, emerge from the gateway. Duvall watched him
+as he proceeded down the street, then began to follow him.
+
+The young man seemed in no great hurry, and at the junction of the
+avenue with the Champs Élysées, Duvall accosted him, speaking in French.
+
+"Do you want to earn twenty francs, my friend?" he asked pleasantly.
+
+The boy regarded him with a quizzical smile. "Who does not, Monsieur?"
+he replied.
+
+"Let me see the note you have in your hand."
+
+The boy drew back suddenly, and made as though to thrust the letter into
+his pocket. "It is impossible, Monsieur," he began.
+
+Duvall took out a gold twenty-franc piece. "I intend to have the letter,
+my man. If you will give it to me peaceably, here are the twenty francs;
+if not, I shall be obliged to take it from you by force."
+
+The boy regarded the detective for a moment, as though contemplating
+flight. Duvall seized him by the collar. "Give me the note," he cried,
+"or I'll call a gendarme and have you placed under arrest!"
+
+The boy allowed the letter to drop to the pavement, seized the
+twenty-franc piece, and took to his heels.
+
+Duvall picked it up. As he had expected, it was addressed to Alphonse
+Valentin, ---- Boulevard St. Michel. He had waited, on the chance that
+Mary Lanahan would lose no time in warning her probable confederate.
+
+The letter gave him the man's address. That was so much accomplished, at
+least. Then he tore it open, and read the contents. They proved more
+mystifying than anything that he had yet encountered in this mysterious
+affair.
+
+"Destroy the cigarettes!" These three words comprised the entire
+contents of the note.
+
+
+
+
+CHAPTER VI
+
+
+Alphonse Valentin came up to Grace and took her roughly by the arm.
+"Come with me," he said, and started up the street.
+
+At first she felt inclined to resist him. A signal to a passing
+gendarme, and she could have had the man placed under arrest. Monsieur
+Lefevre had taken care to provide her with credentials that would insure
+her obtaining instant assistance from any member of the police.
+
+Then another thought came to her. This man Valentin she very much
+desired to see. His position, clinging to the rear of the automobile,
+indicated that he was in all probability not a confederate of the
+kidnappers. Just what he was, she could not imagine. She determined to
+go along with him, and hear what he had to say.
+
+A few minutes' walk brought them to the man's lodgings. For some
+reason, which she did not understand, the automobile in which she had
+been a prisoner had stopped on the Boulevard St. Michel within a short
+distance of Valentin's rooms.
+
+When they reached the house, Valentin, instead of opening the door with
+a key, rang the bell. The woman who had previously admitted Grace came
+to the door. Valentin nodded.
+
+"Is this the woman?" he asked.
+
+"Yes," said the landlady, recognizing her at once. "This is the one."
+
+"Good!" Valentin closed the door and led the way to his room. Grace
+followed, wondering what the man intended to do.
+
+"Why have you come here twice during the past two days?" he asked,
+abruptly, after he had lit the lamp and carefully shut the door.
+
+Grace determined to be quite frank with him. "I wanted to ask you some
+questions, Monsieur Valentin," she replied.
+
+"Ha! You know my name?"
+
+"Certainly."
+
+He appeared somewhat uneasy. "What are you up to?"
+
+"I am trying to find Mr. Stapleton's child."
+
+A queer smile came over the fellow's face. "Is that why you stole the
+cigarettes?" he asked.
+
+"I did not steal them. They were taken by a man with a black beard, who
+came in through the window when I was here."
+
+"A black beard?" He smiled incredulously. "And you let him take them."
+
+"Yes. Why not? Were they of such great value?"
+
+He glanced about uneasily, but did not reply to her question. "Who was
+the man?" he presently asked.
+
+"I do not know. I followed him. He entered Mr. Stapleton's house."
+
+"Sacré! It must have been François!"
+
+"Hardly. François has no beard."
+
+"But he might have been disguised." He seemed very much perturbed. "What
+a pity I was so careless!"
+
+"Monsieur Valentin, will you please tell me what those cigarettes have
+to do with the kidnapping of Mr. Stapleton's child?"
+
+He looked at her closely for a moment. "Everything," he answered
+gloomily, "and--nothing. I was a fool to have left them here."
+
+Grace began to feel more and more composed. This man did not talk like
+one of the band of criminals. "Do you know where the child is?" she
+suddenly asked.
+
+"Perhaps." He observed her narrowly. "Do you?"
+
+"No. If I did, I should restore him to his poor mother."
+
+"What were you doing in that automobile?"
+
+"I was a prisoner. And you?"
+
+Again he evaded her question. "It is my own affair," he growled.
+
+"Did you not see who it was that drove the car?" she asked.
+
+Instead of replying, he flung himself into a chair. "Sit down,
+Mademoiselle, and tell me the whole story. If I find that you are frank
+with me, I promise to be equally so with you."
+
+Suddenly Grace felt an intuition that the man was honest. She determined
+to do as he asked. "Very well. I will tell you the truth. I am trying to
+recover Mr. Stapleton's child. Last night I was watching the house. I
+was seized from behind, thrown into an automobile, and taken--I do not
+know where. This morning a message to Mr. Stapleton was given me.
+Tonight I was brought here, blindfolded, in an automobile. Then I met
+you. That is all I know."
+
+Valentin appeared disappointed. "Then you do not know where the child
+is?" he asked.
+
+"The child is where I was--I saw it."
+
+As Grace said this, her companion leaped excitedly from his chair. "Then
+we have them!" he cried.
+
+"I do not understand."
+
+"Mademoiselle, this evening I was watching Monsieur Stapleton's house.
+Like yourself, I desire to recover the child. I saw François leave in
+Monsieur Stapleton's automobile. I climbed in behind, as he left the
+house. It was dark. He did not see me. He drove out toward Versailles."
+
+"Toward Versailles?" exclaimed Grace.
+
+"Yes. Why do you seem so surprised."
+
+"Never mind. Go on."
+
+"After a time, he stopped by the roadside. I got out, and hid in the
+shadow of some trees. Presently you were brought, blindfolded, by a man,
+who entered the car with you. When it again started, I climbed on
+behind. That is how I came to meet you."
+
+"Then you don't know where the house is, from which I was brought?"
+
+"No. There are many houses--all about. There was no way of knowing, in
+the dark. Did you come far--when they brought you to the automobile?"
+
+"Yes. Several hundred yards, at least. But you know the spot, on the
+roadside?"
+
+"Yes. I can find it, without difficulty."
+
+"Monsieur Valentin, I have a plan--a very dangerous plan--for recovering
+Mr. Stapleton's boy. I cannot tell you what it is now. Tomorrow I will
+tell you--tomorrow afternoon. I shall want your assistance."
+
+"What am I to do?"
+
+"Can you drive an automobile?"
+
+The man smiled. "Decidedly. It is my profession."
+
+"Splendid! You will wait for me here, and I will come, and tell you what
+you are to do. I shall arrive not later than six o'clock." She rose.
+"Now I must go; but before I do so, tell me one thing. What is the
+mystery of the gold-tipped cigarettes?"
+
+Her question seemed to drive from Valentin's face all the good nature
+that had dwelt there the moment before. "I cannot tell you that," he
+growled. "You must not ask me. Let me advise you to drop the matter of
+the cigarettes, and report your message to Mr. Stapleton at once."
+
+For a moment, Grace almost regretted her frankness. Suppose, after all,
+he should prove to be but a confederate of the kidnappers, in league
+with Mary Lanahan, the nurse, to spirit the boy away in the first place,
+and now sent by them, in the guise of a spy clinging to the rear of the
+automobile, to find out what step she proposed to take to capture them?
+She paused in indecision. Suddenly there was a tapping upon the door of
+the room.
+
+Valentin went to the door and cautiously opened it. The landlady stood
+on the landing outside. "There is a man to see you, at the door below,
+Monsieur," she said in a low tone.
+
+"Who is it?"
+
+"I do not know. He gives the name of Victor Girard."
+
+"Very well. Send him up."
+
+Grace heard the name--Victor Girard. A sudden wave of weakness swept
+over her. It was Richard! He had used the name frequently, in the past.
+She heard him ascending the short flight of stairs. There was no escape.
+Yet Monsieur Lefevre particularly insisted that he should not recognize
+her. She hastily drew down her veil. "Get rid of him as soon as you
+can," she whispered to Valentin, and shrunk back into the shadow.
+
+Duvall came in, glancing sharply about him. He had been waiting to see
+Valentin since early in the evening, and had inquired for him twice
+before, only to find that he was out.
+
+"What can I do for you, Monsieur?" inquired Valentin.
+
+The detective drew the note from his pocket--the note which Mary Lanahan
+had sent to Valentin, and which Duvall had intercepted. "This is for
+you, Monsieur?" he asked, then suddenly paused, astounded. In the dim
+light, he caught sight of Grace, standing on the opposite side of the
+room, watching him closely. "I--I thought--Monsieur--I thought you were
+alone," he gasped, his eyes fixed on Grace as though he had seen a
+ghost. "I--I beg your pardon, but--" He was unable to proceed.
+
+Valentin looked at him in amazement. "What is it, my friend?" he asked
+sharply. "Tell me your business, if you please, and go. I have a
+visitor."
+
+"Yes--Monsieur--so--so I see." Duvall pulled himself together with a
+mighty effort and turned his glance to Valentin. He had suffered a great
+shock. For a moment he would have been ready to swear that Grace, his
+dear wife, stood before him in the flesh--and yet the thing was an
+absurdity: Grace, with her golden brown hair, her clear complexion, was
+three thousand miles away! This woman, dark, typically French, was quite
+evidently an entirely different person; yet the resemblance was
+startling--he felt himself shaking in every fiber.
+
+"Well, Monsieur, give me the letter, since you say it is for me," he
+heard Valentin saying.
+
+In an instant he had recovered his self possession. "Here," he
+exclaimed, handing the note to the man before him. "It is from Mary
+Lanahan. I have read it."
+
+"You have read it, Monsieur!" Valentin exclaimed, angrily. "By what
+right, then, do you presume to read my letters?" He took the note and
+hurriedly read its contents. "Sacré!" he exclaimed. "What does this
+mean?"
+
+"It means, my friend, that I want that box of gold-tipped cigarettes."
+
+Grace started. So Richard, too, was interested in the recovery of these
+mysterious cigarettes. What on earth, she wondered, could it mean?
+
+"In the first place, Monsieur, let me inform you that I have no
+cigarettes, gold-tipped or otherwise. In the second place, I question
+your right to make any such demands."
+
+"Does not the note from Mary Lanahan request you to destroy them?"
+
+Valentin turned pale. "I tell you I have no such cigarettes!" he cried.
+
+"Are they not the sort, then, that you usually smoke?"
+
+"I do not smoke at all, Monsieur."
+
+Duvall laughed. "So you both tell the same story, it seems. My friend, I
+dislike to discuss these matters before a stranger." He glanced
+significantly at Grace.
+
+She dared not go. To speak--even to bid Valentin good evening, would,
+she felt sure, betray her. So she remained silent.
+
+"Then take yourself off. I certainly have no desire to discuss them. I
+tell you, I do not smoke--I have no cigarettes--that is enough!"
+
+"What does that note mean, then?" asked Duvall sternly.
+
+"That is Miss Lanahan's affair--and mine."
+
+Duvall drew out his pocketbook, and extracted from it the bit of
+cigarette stump, with the gold tip, which he had found that morning in
+the Bois de Boulogne. "Monsieur Valentin," he said, "I found this end of
+a cigarette at the exact place in the grass, in the Bois de Boulogne,
+where Mr. Stapleton's child and nurse were, when the boy was stolen. The
+chauffeur was asleep. You could readily have walked up, taken away the
+child, and no one would have been the wiser. The story of Mary Lanahan,
+that no one came near her, that the boy disappeared into thin air, is
+absurd. The presence of the half-smoked cigarette, of a kind which I
+have reason to believe you use, convinces me that you were there in the
+Bois, with the nurse, at the time of the kidnapping--if indeed you did
+not take an active part in it. The message from Mary Lanahan, which I
+have just handed you, directing you to destroy the cigarettes,--which,
+no doubt, she feared, after my questioning, might be used as evidence
+against you,--serves as strong additional proof. I believe that you know
+where Mr. Stapleton's child is."
+
+The statements which her husband made convinced Grace that she had made
+a mistake in confiding in Valentin. She herself had seen the
+gold-tipped cigarettes on his table--had seen them stolen. It was not
+very conclusive evidence, she realized; but, taken with the nurse's
+letter, it was significant.
+
+Valentin, however, did not appear to be greatly alarmed by the
+detective's charges. "You are mistaken, Monsieur," he said quietly. "I
+know nothing about the affair."
+
+"Then what does this note mean?"
+
+"That I cannot tell you. And, if you have any other questions to ask, I
+beg that you will come again--at another time. I, as you see, am engaged
+for the moment." He indicated Grace with a glance.
+
+Duvall looked about, then turned to the door. His object in coming had
+been fulfilled. He had seen Valentin--located him--he hoped frightened
+him. It was one of his theories that a man, frightened by the knowledge
+that he is being closely pursued, is far more likely to make a false
+step, than one who fancies himself secure.
+
+He darted a curious glance at Grace, as he left the room; but her face,
+concealed in the shadow, told him nothing. Her silent presence filled
+him with strange disquietude. He stationed himself outside the doorway
+of the house, determined to learn, if possible, who she was, by
+following her, when she left the place. He had not counted on Valentin's
+being with her.
+
+The two left the house together, and the man at once called a cab. Into
+this he put Grace, all the while eying Duvall savagely. The latter gave
+up all ideas of pursuing Grace, and returned, somewhat disgruntled, to
+his hotel. He had barely reached it, when a message was brought to him,
+summoning him to Mr. Stapleton's house.
+
+Grace, meanwhile, had driven at once to the banker's, and delivered to
+him the message with which she had been intrusted by the man in the
+black mask that morning.
+
+Mr. Stapleton's face grew more and more angry as she proceeded with her
+story. He jumped up, as soon as he learned the purport of it, and,
+ringing up Duvall's hotel, requested the detective to come to him at
+once. Then he turned to Grace.
+
+"You have no idea where this place is located?"
+
+"Not the slightest."
+
+"You say you saw my boy? He was safe?"
+
+"I saw a child, which I was told was yours, Mr. Stapleton. I did not
+recognize him, of course. You know I have never seen your son. Also, he
+was dressed as a girl."
+
+Mr. Stapleton produced a photograph with nervous haste. "Was he like
+this?" he demanded.
+
+"Yes. It was the same." There was sufficient resemblance, even in the
+disguise the boy wore, for Grace to be practically certain of his
+identity.
+
+"How am I to know that these scoundrels will keep their word?" Mr.
+Stapleton groaned, his head on his hands.
+
+"Do you intend, then, to give them the money?"
+
+"Certainly. Do you suppose I would take any chances, for the matter of a
+hundred thousand dollars--or twice as much, for that matter? His mother
+and I are unable to sleep, to eat, to do anything in fact, under the
+strain of this thing. I shall by all means do as they ask."
+
+"But they will get away."
+
+"That is nothing to me. Let them. Once my boy is safe, I can spend
+another hundred thousand to catch them; but not now--when one false step
+might mean his death."
+
+"They won't harm him, Mr. Stapleton. They are too anxious for the
+money, to let anything happen to him."
+
+"I'll take no chances."
+
+Grace rose. "Then I might as well be going," she said. "I don't see that
+I can do anything more. I shall report the matter to the Prefect of
+Police at once."
+
+"Very well. And be good enough to say to him that I particularly desire
+that no steps be taken to prevent the carrying out of the plan. I shall
+pay this money and regain my boy. After that, the police may do as they
+like. Good evening."
+
+"Good evening." Grace left the house, feeling singularly disappointed,
+in spite of the fact that Mr. Stapleton's decision apparently meant that
+Richard's work in Paris, as well as her own, was likely to be brought to
+a sudden termination.
+
+As she was leaving the house, she saw Richard drive up in a cab. The
+sight of him filled her with joy; although she was forced to conceal it,
+and pass him by with a look of indifference. In the darkness, she knew
+she was safe. He recognized her of course,--recognized her, that is, as
+the woman he had seen in Valentin's room,--and her presence here at Mr.
+Stapleton's house evidently filled him with surprise. For a moment, she
+thought he was about to speak to her, as he descended from his cab; but
+she turned away and hurried down the street, and when she looked back,
+he had entered the house.
+
+
+
+
+CHAPTER VII
+
+
+Mr. Stapleton was standing in the middle of the library, when Duvall
+entered. He turned to him excitedly.
+
+"Mr. Duvall," he said, "I have just heard news that I hope will restore
+my boy to me within the next twenty-four hours!"
+
+"From the woman who just left the house?"
+
+"Yes."
+
+"Who is she?"
+
+"An agent of the police."
+
+"Ah! Are you certain of that?"
+
+"I know only what she says."
+
+Duvall looked at him curiously. "What is the news she has brought you?"
+
+"A message from the scoundrels who have stolen the child. They want a
+hundred thousand dollars, to return him."
+
+"And she brought you that message?"
+
+"Yes." The banker regarded his questioner uneasily.
+
+"Does it not seem rather singular, Mr. Stapleton, that a member of the
+Paris police should come to you with a message from the kidnappers?"
+
+Mr. Stapleton frowned. "I had not considered that aspect of the case,
+Mr. Duvall. I was--and am--too anxious to get my boy back, to care by
+whom these fellows deliver their terms."
+
+"What was the message, Mr. Stapleton?"
+
+"I am to drive along the road to Versailles tomorrow evening, leaving
+here at eight o'clock, and moving at the rate of twelve miles an hour.
+Somewhere on that road, an automobile in passing will signal me with a
+blue light. I am then to slow up and toss into the other machine a
+package containing one hundred thousand dollars. If I do this, and make
+no attempt to follow or capture the rascals, they agree to deliver the
+child here--at my house--by the time I return home."
+
+Duvall listened to Mr. Stapleton's words with growing interest. "They
+are a shrewd lot," he exclaimed. "They will get away in their machine,
+and have ample opportunity to examine the package to see that it
+contains the amount they demand. By signaling to confederates at any
+point along the road, or in another automobile, they can advise them
+whether or not to return the child."
+
+"But how will they be able to do this, without running the risk of being
+caught?"
+
+"That is easy. They take the boy to Paris, employ a passerby--a man of
+their own class, no doubt--for a few francs, to deliver him at your
+door. To trace them, through that means, will be impossible. If you give
+them the money, the chances are that they will never be caught."
+
+"Nevertheless, I shall give it to them."
+
+"I expected that, Mr. Stapleton. I can understand your feelings. It is
+not right, of course, to submit to this blackmail; but no doubt, were I
+situated as you are, I would do the same thing. Still, it is a great
+pity."
+
+"Why?"
+
+"Because we have an excellent chance to capture these fellows."
+
+"And lose the boy!"
+
+"Yes, that might be true. Such men are apt to retaliate very promptly,
+and very severely. They have no pity. I wish I might handle the case to
+suit myself."
+
+"What would you do?"
+
+"I would arrange to follow you, in a fast car, keeping say five hundred
+feet in the rear. I should have several men, well armed, in the car. By
+watching carefully, with field glasses if necessary, I would observe the
+car which signaled you with the blue light. When this car passed me, I
+would follow, but make no move which would alarm the kidnappers until
+they had given the signal--whatever it is--that would ensure your boy
+being returned to you. Then I would close in on them, and arrest them."
+
+"Your plan, Mr. Duvall, is open to serious objections. Suppose these
+men, undoubtedly on the watch, observe that they are being followed.
+They will give no signal--and I will lose not only my child, but the one
+hundred thousand dollars as well. No, no, I want no interference in the
+matter whatever."
+
+Duvall remained a moment in silence. "Very well, Mr. Stapleton, I am
+under your orders, of course. But I dislike very much to see these
+fellows get away."
+
+"So do I; but there's no help for it."
+
+"If I can work out a plan for their capture, which will not involve the
+loss of the boy, you are willing, I take it, to let me go ahead?"
+
+"Yes; but I insist that you first submit the plan to me."
+
+"Very well. And now, another matter. This woman who brought the message
+to you is, you say, an agent of the police. Did she attempt to explain
+how she came by the message?"
+
+"Yes. She was forcibly abducted, last night, carried a long distance out
+into the country, and the instructions given her. She was brought back
+to Paris, blindfolded, tonight."
+
+"Mr. Stapleton, what would you say were I to tell you that less than an
+hour ago I saw this woman in the rooms of Alphonse Valentin, a man whom
+I suspect to be very deeply concerned in the kidnapping of your son?"
+
+Stapleton started. "Is it possible?" he said. "Have you any idea what
+she was doing there?"
+
+"No. They seemed on excellent terms, however. Of course, it is not
+impossible that an agent of the police might pose as a friend of one of
+the criminals, and thus obtain information. But it looks decidedly
+queer."
+
+"It does, indeed. Still, as I said before, if I get my boy back, I shall
+be satisfied." He took a turn about the room, chewing nervously upon
+his long black cigar. "Now, Mr. Duvall, what is your plan to capture
+these fellows?"
+
+Duvall sat in deep thought for sometime. "It is not an easy matter, Mr.
+Stapleton, but there is one way which promises success, and that, too,
+without interfering with your arrangements to recover your boy."
+
+"What is it?"
+
+"This. It is necessary for us, in some way, to identify the car which
+gives you the signal of the blue light. It will pass close to you, at a
+moderate speed. I want you to mark that car, so that it may be
+recognized at once."
+
+"How can I do that?"
+
+"I will place in the bottom of your machine a small device, consisting
+of a rubber bulb, equipped with a small nozzle, projecting through a
+hole in the body of the car. The bulb will be filled with indelible red
+stain. When you stand up, to toss the package of money to the
+kidnappers, you must press this bulb with your foot. The two cars will
+then be side by side. The pressure on the bulb will discharge a blast of
+the red stain against the body and wheels of the car opposite you. It
+will then be a simple matter to identify it."
+
+"Yes--yes. I see that. But what then?"
+
+"The car, in passing you, will be headed for Paris. Undoubtedly it is
+the intention of these fellows to enter the city. I shall station myself
+at the Porte de Versailles, and I will arrange to have other men,
+members of the detective bureau, stationed at the neighboring gates in
+the fortifications. All cars entering the city will be momentarily
+halted. The one which bears upon its body or wheels the red stain will
+be seized, its occupants arrested."
+
+"But suppose they have not yet notified their confederates to return the
+boy to me?"
+
+"In that event, I feel certain that the child will be found in the
+automobile with them. Look at the thing as you would, were you in their
+place. They are forced to act with great quickness. Were they to signal,
+by lights or otherwise, to persons along the road, they could hardly
+hope to get the boy to your house before you yourself return there. They
+know you will return home immediately at your best speed as soon as you
+have delivered the money to them. What more likely, then, that they will
+have the boy with them in the car, will drive to some prearranged point
+in Paris, and deliver him to the person who will bring him to your
+house? That would seem, to my mind, their most probable plan."
+
+"And if not--if the child is not with them?"
+
+"Then there are but two courses open to them. The first is to signal, by
+lights or otherwise, to their confederates, before they enter Paris. If
+they do this, the boy will be returned to you, and we will capture the
+men as well. The only other alternative, of course, is for them to
+notify their confederates after they enter Paris."
+
+"But, if you arrest him at the barrier, they cannot do that, and my boy
+will not be sent back."
+
+"That is true; but I do not think they will wait to notify their
+confederates until after they enter Paris."
+
+"Why not, Mr. Duvall?"
+
+"First, because of the danger of being observed, in the crowded streets
+of the city. Secondly, because I do not think the child is in Paris at
+all. The woman who brought you the message from the kidnappers, I
+understand, saw the child at a point some distance in the country. It
+seems unlikely that these men would run the risk of conveying the child
+into the city, in broad daylight. By having the boy with them in the
+car, they avoid all danger of signaling anybody. They merely inspect the
+package of money, run into Paris, fully believing themselves for the
+time being safe, drop the child at a convenient point, divide the
+plunder, and scatter to their respective hiding places. Criminals of
+this sort know perfectly well that they are far safer, hiding in a big
+city, than fleeing through the country in an automobile. I feel scarcely
+any doubt that they have the child with them."
+
+"But if he is still in the country, and they wait until after they are
+in Paris before notifying their confederates?"
+
+"Then the latter are obliged to journey a long distance out into the
+country, get the child, and bring him back to your house. That would
+require a considerable period. They could not possibly do it before you
+return home."
+
+Mr. Stapleton considered the matter for a long time in silence. "Your
+arguments seem sound, Mr. Duvall," he presently observed. "Like
+yourself, I am anxious to capture these fellows. It makes my blood boil,
+to think of their getting away. Of course, your deductions may be
+wrong."
+
+"Then at least we will get the perpetrators of the crime, and it is most
+likely that one of them, at least, may be persuaded to turn state's
+evidence, and disclose the whereabouts of your son."
+
+Mr. Stapleton pondered the matter with great care. Evidently he feared
+any course of action which did not insure the return of the child.
+
+"It seems to me, Mr. Stapleton," the detective went on, "that you owe it
+to the public to let me make this effort to capture these fellows. It is
+a grave danger to the community, to have such rogues at large. Let me
+try my plan. Even if it fails, you are no worse off than you are now.
+The attempt cannot in any way be traced to you."
+
+"Very well," said the banker, nervously. "It is a chance--that's all.
+However, since it seems to involve no breach of faith on my part, I am
+willing to take it."
+
+"Good! I will bring the device I spoke of to your house tomorrow, and
+attach it to your car. Your man François will drive you, I presume."
+
+"Yes."
+
+"You trust him?"
+
+"I have no reasons for not doing so. And besides he will know nothing of
+the affair. His part will be merely to drive the car, as I direct him."
+
+Duvall thought for a moment. "You will not, of course, give him his
+instructions until the last moment--just before you start."
+
+"No. That will be best, I think."
+
+"Undoubtedly. And to avoid any possible interference, I think I had
+better not attach the identifying device of which I have spoken to your
+car until late tomorrow afternoon, immediately before you set out. Then,
+if by any chance your chauffeur is in this plot, he will have no
+opportunity to give a warning."
+
+"Very well. I think, however, that your precautions are needless. There
+has been nothing whatever brought out to connect François with this
+matter."
+
+"I know; but it is well to be careful. You will leave here tomorrow
+evening, at eight o'clock?"
+
+"Yes. Promptly at eight."
+
+"You might do well to have someone with you, some member of the police,
+perhaps."
+
+"The instructions expressly forbid it."
+
+"Ah--I see. These fellows are shrewd." He took up his hat. "Until
+tomorrow then. Good night."
+
+"Good night."
+
+
+
+
+CHAPTER VIII
+
+
+At the same hour that Richard Duvall was arranging with Mr. Stapleton
+his plan for the capture of the kidnappers the following day, Grace was
+closeted with Monsieur Lefevre, the Prefect of Police, in the latter's
+library, going over the affair in all its details. The Prefect was
+speaking, ticking off on his fingers the points in the case as he
+proceeded.
+
+"First, we have the impossible story of the nurse, Mary Lanahan. She
+seems to be telling the truth; yet I believe she is lying. In my
+opinion, she is deeply concerned in the whole matter."
+
+"But what about the attempt to poison her?"
+
+"It is highly probable that she poisoned herself, taking a slight dose
+only. This would divert suspicion from her."
+
+"I see."
+
+"Then we have the case of Alphonse Valentin, and the mysterious
+gold-tipped cigarettes. Your husband, Monsieur Duvall, I am informed,
+has found one of these cigarettes, partly smoked, on the grass at the
+scene of the crime. This might indicate that Valentin was there, with
+her, on some occasion, but not necessarily on the day the kidnapping
+occurred. It might readily have been the day before--or the week before,
+for that matter."
+
+"I thought of that," remarked Grace, quietly. "It seems to me that
+Richard attached too much importance to the matter."
+
+"That remains to be seen. Now, supposing Valentin to be concerned, with
+the nurse, in the plot. He of course does not think, at the start, that
+the possession of the cigarettes would involve him in the affair,
+because he does not know that Monsieur Duvall has found the one in the
+grass. Your husband, however, asks Mary Lanahan what kind of cigarettes
+Valentin smokes. She at once becomes suspicious, and at the first
+opportunity warns Valentin, by letter, to destroy them. That shows
+clearly that they are working together."
+
+"Undoubtedly. But meanwhile the cigarettes are stolen from Valentin's
+room by a man with a dark beard, who subsequently enters Mr.
+Stapleton's house. For that, I confess, I can find no explanation."
+
+"Nor I. The destruction of the cigarettes could be of no importance to
+anyone, except to the kidnappers themselves. It is of course possible
+that someone else in Mr. Stapleton's house--François, for instance--is
+concerned in the plot."
+
+"But the man who took the cigarettes had a black beard, while François
+is smooth shaven."
+
+"I know. But it might have been a disguise."
+
+"I do not think so. The man I saw was taller than François, and not so
+heavily built."
+
+The Prefect considered the matter for a moment. "You are certain that he
+entered the Stapleton's house?"
+
+"Absolutely certain. I saw the gate close behind him."
+
+"Then I can only say that, so far, the matter is inexplicable. Now let
+us come back to Valentin. He claims to be working to capture the
+kidnappers--in order to clear the nurse, whom he loves."
+
+"That is as I understand it."
+
+"He denies that he smokes, yet offers no explanation of the presence of
+the cigarettes in his room."
+
+"None. Further, someone sends a note to Valentin, advising him that the
+writer is suspicious of François--suggesting that he watch him. Can this
+mean that François is in the plot, and they fear he may be
+weakening--preparing to turn against them?"
+
+"It certainly looks that way."
+
+"I wish I could see one of these famous cigarettes."
+
+Grace laughed suddenly. "Why," she exclaimed, "I have one in my
+pocketbook. I had quite forgotten it." She opened her purse and took out
+the slender white cylinder.
+
+Lefevre examined the thing closely. "An Egyptian cigarette of American
+make," he mused. "Expensive, here in Paris, and rarely used, except by
+Americans."
+
+"That is true; yet I understand that this man Valentin has lived a great
+deal in America."
+
+For a moment the Prefect did not reply. Then a puzzled look crossed his
+face. "This is a woman's cigarette," he exclaimed. "No man would smoke
+such a thing." He brought his hand down sharply upon his knee. "My
+girl, it is not impossible that the child was stolen not by a man at
+all, but by a woman."
+
+"A woman, apparently, that both Valentin and the nurse are trying to
+shield."
+
+The Prefect sat for a moment buried in thought. Then he glanced at Grace
+keenly. "It seems to me," he remarked, in a quiet tone, "that we should
+endeavor to determine whether or not Mrs. Stapleton is in the habit of
+using cigarettes."
+
+"Mrs. Stapleton!" gasped Grace, in amazement.
+
+"Yes. I confess the idea is a new one, to me; but it may prove of
+interest."
+
+"But why should the boy's mother wish to kidnap him?"
+
+"I do not know. There is but one point of significance. During the past
+week my men have, naturally, questioned Mrs. Stapleton closely as to her
+movements during the past two or three months. They did this, to
+determine, if possible, whether the criminals were of Paris, or from
+some other place, where Mrs. Stapleton may have been, with the child,
+during the past winter. You know these fellows work in bands, and have
+their regular field of operations."
+
+"I see. And where had she been?"
+
+"Monte Carlo!" The Prefect uttered the two words significantly.
+
+Grace was quick to grasp his meaning.
+
+"Then you mean that possibly Mrs. Stapleton may have lost large sums at
+the gambling tables, and, fearing to tell her husband of her losses, has
+enlisted the services of the nurse, and of her friend Valentin, and
+spirited the child away for a few weeks, in order to get the sum of one
+hundred thousand dollars from her husband without his knowledge?"
+
+"It is by no means impossible. I would recommend that you investigate
+the matter thoroughly. If we find that Mrs. Stapleton uses gold-tipped
+cigarettes of this variety, it may go far toward a solution of the whole
+affair."
+
+Grace, remembering Mrs. Stapleton's grief-stricken appearance, felt that
+the clue was a very slender one, but determined to follow it up,
+nevertheless.
+
+"Now," went on the Prefect, "we come to the sudden and most unexpected
+appearance of Valentin, clinging to the rear of the automobile that
+brought you back to Paris tonight."
+
+"As I have told you, he claims to have clambered into Mr. Stapleton's
+car."
+
+"Driven by François?"
+
+"Yes."
+
+"And you say the man who drove the car had a black beard--the same man,
+in fact, who broke into Valentin's room and stole the cigarettes?"
+
+"Yes."
+
+"Then either Valentin is lying, or the man with the black beard is
+François. Let us look at his story from both sides. If he is telling the
+truth, then François is one of the kidnappers."
+
+"So it would seem. You are having him watched, you say?"
+
+"Yes. My men report that he did leave the house, in Mr. Stapleton's
+automobile tonight, at about nine o'clock. That would seem to agree with
+Valentin's story. They also report that he returned about eleven,
+alone."
+
+"They did not follow him?"
+
+"No. It is impossible to do so, in another car, without arousing his
+suspicion, and putting him on his guard. We do not wish him to know that
+he is being watched."
+
+"But Mr. Stapleton must know where he has been--why the car was out."
+
+"Yes. We have questioned him. He says the man reported that the gasolene
+tank was leaking, and that he ordered him to have it repaired at once."
+
+"And was it repaired?"
+
+The Prefect smiled. "Yes. The car was at a garage in the Boulevard St.
+Michel from half past nine until half past ten."
+
+Grace fell back, astonished. "Then Valentin is lying!" she cried.
+
+"So it seems; unless, of course, François took out another car from the
+garage, while his own was being fixed."
+
+"They would know that at the garage."
+
+"They deny it. But these fellows all hang together. They would think
+nothing of protecting a brother chauffeur, in the matter of a little joy
+ride."
+
+"Valentin says nothing about this, in his story."
+
+"He may have omitted it, as an unimportant detail. I mean that he may
+have slipped into the second car, as he did into the first, without
+being observed. It was dark of course. He may not have thought it
+necessary to mention it. All this, of course, is on the assumption that
+he is telling the truth. Now let us say that he is lying--that the man
+with the black beard is not François, but someone else concerned, with
+Valentin in the plot. What is the purpose of his tale?"
+
+"I cannot imagine. Can you, Monsieur?"
+
+"No, not immediately. The first contradiction, of course, is this. If
+Valentin and the man with the black beard are working together, why
+should the latter have broken into his room to get the cigarettes?"
+
+"There seems no sense to it."
+
+"Yet he may have realized the danger of the cigarettes being in
+Valentin's possession, and instead of trying to warn him simply came and
+took them away. It is not a particularly plausible explanation; but let
+us admit it, for the moment, in order to get ahead with our reasoning.
+Suppose Valentin, the man with the black beard, and Mary Lanahan, the
+nurse, to be all working together, either with Mrs. Stapleton, or with
+outside parties. They have the child safely hidden. They abduct you, and
+send the message to Mr. Stapleton through you. They do not trust you,
+knowing, no doubt, that you are an agent of my office. They send
+Valentin along, on the back of the machine, to pretend to be an enemy of
+theirs trying, like yourself, to recover the child. He thus gets into
+your confidence. He advises you to report your message from the
+kidnappers to Mr. Stapleton at once. He questions you, and learns that
+you do not know the location of the house where the child is hidden. He
+then offers to show you as nearly as he can where the house is located.
+If he is in league with the kidnappers, he will take you, and the men
+whom tomorrow I shall send with you, to some location miles removed from
+the actual point where the child is concealed, and you will waste the
+day in a useless search. Decidedly it would be a clever move on their
+part."
+
+"It certainly would."
+
+"Further, you told this fellow that you had a plan to capture the
+scoundrels. You are to acquaint him with that plan, tomorrow afternoon.
+If you do so, he will no doubt get to the telephone on some pretext and
+warn his comrades of what you intend to do. I strongly recommend that
+you put no faith in the fellow whatever."
+
+"Still, you would advise trying to locate the house, as he suggests?"
+
+"Yes, we may be wrong about him. We must leave no stone unturned. And
+now we come to your interview with Mr. Stapleton. You gave him the
+message, of course. What did he say?"
+
+"He said that he intended to carry out the instructions I gave him to
+the letter--pay these fellows their money, and get back the boy."
+
+Monsieur Lefevre uttered an exclamation of anger. "Sacré! He must not do
+that! The stupid fellow! He will spoil everything!"
+
+Grace laughed quietly to herself. "Hardly stupid, Monsieur! The poor man
+is half mad over the boy's loss. He will do anything, to get him back. I
+can scarcely blame him."
+
+The Prefect held out his hand. "I beg your pardon, my child. You are
+right. It is perhaps but natural for him to feel as he does. But there
+are other things at stake, than the recovery of the child. For Monsieur
+Stapleton to pay over this huge sum to these criminals, and then to
+allow them to escape, is not only a grave reflection upon the efficiency
+of the Paris police, but is an injustice to the public as well. If these
+men are successful in this attempt, they will make others. Other
+children will be stolen. I cannot permit it. It must be prevented at all
+costs. These men must be brought to justice."
+
+"How can you prevent it, Monsieur? Mr. Stapleton is determined."
+
+"That, my child, is the question. I cannot stop Monsieur Stapleton if
+he wishes to drive out the road to Versailles and toss a hundred
+thousand dollars into the first automobile that passes him, showing a
+blue light." He rose and began to walk up and down the room.
+
+"I have a plan, Monsieur," said Grace, quietly.
+
+"What is it, my child?" The Prefect regarded her with an indulgent
+smile. He was very fond of Grace. He regretted that he had been unable
+to secure the services of her husband in this case. He knew, from past
+experience, her cleverness; but he did not believe that in a matter of
+this sort she would be able to outwit men who were probably among the
+shrewdest criminals in Paris.
+
+"First," said Grace, "we will have the location pointed out to us by
+Valentin thoroughly searched."
+
+"Assuredly! It will, however, probably result in nothing. Even if
+Valentin is telling the truth, these fellows will beyond question have
+moved the child before now to prepare for the work of tomorrow evening."
+
+"Possibly. At any rate, we will try. After that, I shall want Valentin
+to drive a motor car for me. He is an accomplished chauffeur."
+
+"You will take him into your confidence, then?" asked the Prefect, in
+some alarm.
+
+"No. I shall tell him nothing, except that he is to drive the car, and
+where."
+
+"Very well. But be careful. What next?"
+
+Grace leaned over and spoke to the Prefect in low tones for several
+minutes. He listened to what she said, occasionally smiling, and nodding
+his head. Presently he brought his hand down sharply upon the table.
+"Bravo!" he exclaimed. "You were born to be a detective. We will get the
+kidnappers, the money, and in all probability the child as well. I
+congratulate you!"
+
+"You think it will work, then?"
+
+"I do not see how it can fail. It is an inspiration. I shall certainly
+feel very well satisfied indeed, if I can return to Monsieur Stapleton
+both his child and his money, and at the same time place the kidnappers
+behind the bars. I could never permit it to be said that the police of
+Paris would knowingly allow a desperate band of criminals to get away
+with half a million of francs without lifting a hand to prevent it." He
+rose and glanced at his watch. "Come, my child. It is after midnight.
+You have had a long and exciting day. You had better get some rest."
+
+Grace rose. "Richard seemed awfully puzzled when he saw me."
+
+"Did he?" The Prefect laughed mischievously. "Really it is a great joke
+upon him. To be within a step of his own wife, and not to know her!"
+
+Grace seemed scarcely to appreciate the humor of the situation. "I think
+it's a shame," she said, "Poor Richard. He'll never forgive me. I really
+think I ought to tell him."
+
+Monsieur Lefevre shook his head. "If you do that, my dear child,
+everything will be spoiled. He will insist upon your dropping the case
+at once, and that would certainly not be fair to me."
+
+"But, Monsieur, after all, you really do not need me, with all the
+clever men you have upon your staff."
+
+"Who knows? Perhaps you may succeed, where they will fail. I have great
+faith in the intuition of a woman. And already you have advanced the
+case further in forty-eight hours than my men have done in ten days. It
+was a chance, I will admit, that these rascals should have chosen you to
+deliver their demands to Monsieur Stapleton. I confess I do not
+understand their reasons for doing so. They must have known that
+besides telling your story to him, you would also tell it to me. It may
+have been sheer bravado on their part--it is a characteristic, I have
+noted, in many criminals. They seem to glory in defying the police.
+These fellows, no doubt, think that they have matters so arranged that
+capture is impossible. I think we shall give them a little surprise."
+
+He turned to the door, and held it open, allowing Grace to pass into the
+hall. "Good night, my child," he called out to her, as she began to
+ascend the stairs. "I think I will smoke one more cigar."
+
+As for Grace, she lay awake a long time, thinking of Richard, of their
+home in the country, of the happy hours they had spent there--before
+this unexpected interruption to their honeymoon. It seemed very queer to
+her, to be lying there, alone. She had not gotten used to it. And
+somewhere, in this big city, Richard was also sleeping--and she not with
+him! The excitement of the affair was beginning to die out. The meeting
+with Richard on the boat, which she had planned when she set out from
+home, had not materialized. She had postponed this meeting, in her
+thoughts, until his arrival in Paris, and now--he had come, and still
+she had not been able so much as to touch his hand. She finally went to
+sleep, devoutly praying that tomorrow, and the capture of the
+kidnappers, would mark the end of their needless and cruel separation.
+
+
+
+
+CHAPTER IX
+
+
+Promptly at eight o'clock the next evening Mr. John Stapleton left his
+house in the Avenue Kleber, in a big French touring car, with François
+at the wheel.
+
+The car presented no points of peculiarity, being like a thousand others
+to be seen any evening upon the streets of Paris. It was of large size,
+high powered, and painted a green so dark as to be almost black.
+
+Mr. Stapleton sat in the tonneau, wearing a dark blue serge suit, and a
+Panama hat. In his left hand he clutched a small package, about the size
+of a cigar box. In the package were banknotes amounting to one hundred
+thousand dollars.
+
+Close beside his right foot lay a rubber bulb, from which a short pipe
+extended through a hole bored in the side of the car. The end of the
+pipe held a small brass nozzle. It projected but a short distance beyond
+the body of the car, and in the dim light of early evening was quite
+invisible.
+
+Mr. Stapleton told his chauffeur to drive out the road toward
+Versailles. "I feel like getting some fresh air," he added. "It's rather
+warm, tonight." Inwardly he was burning up with excitement.
+
+From Paris to Versailles is a matter of some fourteen miles. Mr.
+Stapleton's car proceeded slowly. He wanted to run no chances of missing
+the car with the blue light.
+
+At the Porte de Versailles he paused long enough to see Richard Duvall,
+standing in the shadow of the gateway. Then he passed outside of Paris.
+
+There were many automobiles and other vehicles on the road. The evening
+was a pleasant one, and all Paris seemed out taking the air. The
+majority of the vehicles were coming toward the city. He observed a car,
+some distance behind him, containing a single occupant, a man of middle
+age, but paid no attention to it. His eyes were strained to detect in
+the cars approaching him some evidence of the signal light which was to
+rouse him to sudden action.
+
+He noticed that François, like himself, was carefully scrutinizing each
+car as it approached them. He wondered if the chauffeur could have any
+idea of the purpose of his expedition; but presently dismissed the
+thought as entirely unlikely, and devoted himself to the passing cars.
+
+He had proceeded perhaps four or five miles beyond the fortifications,
+when he saw a large car approaching slowly from the direction of
+Versailles. It contained but two persons, the chauffeur, and a heavily
+veiled woman.
+
+The chauffeur, who was keenly observing the machine in which Mr.
+Stapleton sat, began to swerve to the right side of the road, so as to
+pass as closely to the banker's car as possible. At the same moment
+there showed through the gathering darkness a brilliant spot of blue
+light in the tonneau where sat the woman.
+
+Mr. Stapleton was on his feet in an instant. The two cars approached
+each other rapidly. It was necessary for him to act with great
+quickness. He shifted the package containing the money from his left
+hand to his right, and a moment later had tossed it lightly into the
+other car.
+
+He saw at once that it landed safely within, and at the same instant he
+pressed his foot down hard upon the rubber bulb. In a moment the car
+with the blue light had swept past, and was disappearing rapidly in the
+direction of Paris.
+
+Mr. Stapleton leaned forward and addressed François in a voice which
+quivered with excitement. "Drive home at once," he commanded.
+
+In a moment he was following the first car toward the city.
+
+He did not notice, as he swept down the darkening road, the car which
+had been following him all the way from Paris. It continued on its way
+toward Versailles. In it were two people. At the wheel sat a man who
+bore, in the semi-darkness, a striking resemblance to François, Mr.
+Stapleton's chauffeur, while in the rear sat a figure, in dark suit and
+Panama hat, which seemed for all the world like that of the banker
+himself. Had a casual observer not seen Mr. Stapleton turn back toward
+Paris, he would have concluded that he was still on his way toward
+Versailles.
+
+The occupants of this second car also appeared to be keenly watching the
+various automobiles which passed them, as though expecting some signal,
+some recognition; yet, in spite of their eager and expectant glances,
+they seemed doomed to disappointment.
+
+At last Versailles was reached. The elderly man in the tonneau gave a
+short command, his chauffeur turned the car about, and they began to
+return to Paris. Nothing further whatever happened on the Versailles
+road.
+
+Meanwhile, Richard Duvall, at the Porte de Versailles, was carefully
+scrutinizing the various incoming machines that passed the gate and
+entered the city. With a brilliant electric searchlight he examined
+their bodies and wheels, looking always for the telltale red stains
+which would identify the kidnappers' car. Beside him stood Vernet, one
+of the Prefect's assistants, with whom Duvall had become well acquainted
+during his former stay in Paris.
+
+"Well, Monsieur Duvall," remarked the latter, "a most ingenious
+plan--this of yours. I wonder if it will be successful?"
+
+"I feel sure of it."
+
+"I hope you are right." He looked at his watch. "Half past eight. About
+time, I should think, from what you tell me. Here is a big fellow, now.
+A Pasquet, by her looks. Six-cylinder, too."
+
+Duvall glanced at the oncoming car. A wagon which preceded it was just
+passing the gates. The big Pasquet slowed up, and almost stopped.
+
+The detective threw the rays of his searchlight on the body of the car,
+then started back with an exclamation. From one end to the other, the
+dark green finish of the sides and wheels was spattered and streaked
+with bright red paint. Dust had settled in it, in places, especially on
+the wheels; but above, on the doors, it was clear and unmistakable.
+
+"Vernet," he shouted, excitedly, "it is the one! Quick! Don't let them
+get away."
+
+Vernet stepped up to the quivering motor. At the wheel sat a young man,
+quite composed. In the tonneau, a veiled woman reclined at ease. In her
+hands she held a brown paper package.
+
+She leaned toward Vernet, and spoke a single word to him. Duvall did not
+hear what it was; but its effect upon the Prefect's man was
+instantaneous--electrical. He stepped back and raised his hat. "Pardon,
+Madame," he said, and the Pasquet rolled through the gate and into the
+streets of Paris unmolested.
+
+Duvall had sprung forward, and, as he did so, swept the occupants of the
+car with his electric searchlight. Suddenly he drew back in amazement,
+just as Vernet allowed the car to pass on. He could scarcely believe
+that what he saw was a reality. There was the big black car, its body
+and wheels plentifully bespattered with the identifying red stain--and
+there, at the wheel, sat Alphonse Valentin, while the veiled woman in
+the rear was--Grace!
+
+He did not know it was Grace--he did know that it was the woman who had
+been with Valentin in his room, who had brought the message from the
+kidnappers to Mr. Stapleton, who, in some far off and intangible way,
+reminded him of Grace.
+
+There she sat, in her hand the package containing Mr. Stapleton's
+money--and Vernet doffed his cap to her, and permitted her to go on! Was
+this woman, then, hoodwinking even the police?
+
+He sprang to Vernet's side. "Stop them!" he cried, in a hoarse voice.
+"They are the ones I am after."
+
+Vernet shook his head. "Impossible, Monsieur. They are given safe
+conduct by Monsieur the Prefect himself."
+
+"But--they are thieves--kidnappers!"
+
+Vernet shrugged his shoulders. "It may be so, Monsieur Duvall; but my
+orders are to let them pass."
+
+The detective ground his teeth, helpless. His scheme for identifying
+the criminals had worked perfectly. He had found them, only to see both
+them and Mr. Stapleton's hundred thousand dollars as well slip quietly
+through his fingers. He cursed the whole police force of Paris roundly,
+in his anger.
+
+The arrival of another car distracted his attention. It was Mr.
+Stapleton, hurrying home, in the hope of finding his boy. Duvall did not
+stop him. The banker was evidently thinking of nothing but his lost son.
+
+Several other cars passed. Duvall had no interest in them. He was about
+to turn away, with the intention of hunting up Mr. Stapleton and
+learning whether or not the boy had been returned to him, when he heard
+a familiar voice calling him by name. He turned. It was Monsieur
+Lefevre, in a big dark green car.
+
+"Mon Dieu! Duvall!" the Prefect cried, in pretended surprise. "You here!
+In Paris! Or do my eyes deceive me?"
+
+The detective looked a bit sheepish. He realized that in not calling on
+his old friend before now, he had been guilty of an apparent rudeness
+which Monsieur Lefevre might justly resent. "Monsieur," he cried, "it is
+indeed I." He put out his hand, and grasped that of his old chief
+warmly. "A little matter of business brought me to Paris. I have only
+just arrived."
+
+"Indeed." The Prefect's eyes twinkled. "I hope, my dear fellow, that
+your other engagements will permit you to come and see me before long."
+
+"I shall come this very evening, Monsieur. In fact, I have a matter of
+the utmost importance to discuss with you. Shall you be at liberty?"
+
+"In an hour, _mon ami_. Until then I have other things to occupy me.
+Come to the Prefecture in an hour. I shall be waiting for you. For the
+present, adieu." He called an order to his chauffeur, and drove rapidly
+off into the darkness.
+
+Duvall turned on his heel and began to look for a taxicab. "Good night,
+Vernet," he called out, as he went up the street.
+
+In half an hour, he had reached Mr. Stapleton's house. He found the
+unfortunate banker striding up and down his library in a towering rage.
+"The fellows have deceived me!" he cried. "They have not brought back my
+boy. Did you see anything of them? Tell me!" He grasped Duvall nervously
+by the arm.
+
+"The car into which you threw the package of money contained, besides
+the chauffeur, but one occupant, a woman, did it not?"
+
+"Yes--yes! Did you get her?"
+
+"No."
+
+"Why not? Did your scheme to identify the car fail to work?"
+
+"On the contrary, it worked perfectly. I stopped the car at the barrier.
+The woman in it had the package of money in her hand."
+
+"And you did not arrest her! In Heaven's name, why not?"
+
+"The police would not permit me to do so. The woman was the same one who
+brought you the message last night, the supposed agent of the police.
+They allowed her to pass the gates."
+
+"What?" the banker fairly shouted his question. "This is ridiculous! Is
+the woman a criminal, or is she a detective? She cannot be both, and if
+she is the latter why was she in that car, with my money in her hand?"
+
+"I do not know. But I mean to find out very shortly."
+
+"How? I'd like to know!"
+
+"I am going to see the Prefect of Police at once."
+
+Mr. Stapleton sank into a chair, and groaned. "I had hoped to have Jack
+with me by now. His poor mother is distracted. Isn't there anything, Mr.
+Duvall, that you can do?"
+
+"I hope to answer that question better, Mr. Stapleton, after I have seen
+Monsieur Lefevre. If this woman, and her companion, Valentin, are really
+the kidnappers, they are in Paris, and we shall be able to lay our hands
+on them without difficulty. If they are not, your money, at least is
+safe. I must leave you now; but as soon as I learn anything, I will
+report to you at once. Good night."
+
+He left the house, more mystified than he had ever been in his life.
+From the start, this case had apparently been one in which all the clues
+led to absurd contradictions, or else to nothing at all.
+
+In fifteen minutes he was at the Prefecture.
+
+Monsieur Lefevre sent out word that he would be occupied for a few
+moments, and the detective sat down as patiently as possible, to wait.
+
+
+
+
+CHAPTER X
+
+
+The events of the Versailles road left Grace Duvall in a high state of
+good humor. The plan she had suggested had been a success--at least so
+far as her own part in it was concerned. How Monsieur Lefevre had fared,
+she did not yet know. She looked down at the brown paper package she
+held in her hand, and ordered Valentin to drive to the Prefecture.
+
+The day had been an eventful one. Immediately after breakfast Grace had
+gone to Mr. Stapleton's house and had a long interview with Mrs.
+Stapleton. That lady, apparently quite prostrated from worry and alarm
+over the fate of her son, received her in her boudoir, where she lay, a
+charming picture, upon a divan.
+
+Grace had no more than entered the room, when she detected the odor of
+cigarette smoke, faint but unmistakable. She glanced at the table which
+stood beside the divan upon which Mrs. Stapleton lay. On it, a tiny
+porcelain ash receiver contained a fluffy mass of gray-white ashes, and
+the half smoked remains of a cigarette. The tip, partly covered by the
+ashes, was of gold.
+
+The girl engaged her hostess in a long conversation, quieting her fears,
+which seemed real enough, and predicting the early recovery of her boy.
+It was quite evident that Mrs. Stapleton was terribly nervous. No doubt
+this accounted for the cigarettes. Although Grace did not use them
+herself, she knew how their quieting effect on the nerves made them
+almost necessities, at times, to their devotees.
+
+Presently she observed that Mrs. Stapleton held within her left hand,
+concealed beneath the folds of her kimono, a small pasteboard box, a box
+of cigarettes. Grace determined upon a bold move.
+
+"May I have one of your cigarettes, Mrs. Stapleton?" she asked, in her
+sweetest manner. "I've forgotten to bring any with me--and--you know how
+it is."
+
+Mrs. Stapleton's features relaxed into something approaching a smile.
+She had been lying there wondering whether she dared offer one to Grace,
+and thus be able to sooth her own overstrained nerves. She brought
+forth the box and extended it toward her visitor. Grace took one of the
+tiny cylinders and lit it. _It was of the same make as the one she had
+secured in Alphonse Valentin's room!_
+
+She took her departure a little later, wondering greatly. The whole
+affair had begun to take on an air of baffling contradiction.
+
+She spent the rest of the morning, and most of the afternoon, searching
+the houses near the point on the road to Versailles indicated by
+Valentin. With her were three men from the Prefect's office--silent,
+able men, in plain clothes, who pretended to be keepers from the _Jardin
+des Plantes_, in search of a dangerous cobra, which was supposed to have
+escaped from its cage the night before.
+
+The terrified householders threw open their doors with unassumed
+alacrity. The suggestion of a deadly reptile lurking in their gardens
+was a veritable open sesame. Yet no traces of the missing boy were
+found, and, more remarkable still, Grace was unable to identify any of
+the many gardens as the one in which she had seen the child playing with
+the spaniel. This disappointed her greatly. She knew well that, if
+Valentin was telling the truth, the garden was here; yet, although they
+visited every house within a quarter of a mile, they were unable to
+locate it. She remembered now that in her agitation, her eager
+examination of the child, she had not fixed upon her mind any salient
+point in the garden itself. All that she remembered was a bit of grass,
+a gravel walk, and the child playing with the dog. A dozen of the little
+enclosures presented similar features. She returned to the prefecture,
+baffled.
+
+"The fellow is undoubtedly lying," had been Monsieur Lefevre's comment.
+"He is trying to throw you off the track, in order to protect the nurse,
+and possibly Mrs. Stapleton as well. I should not be surprised to find
+that the boy's mother is the guilty person."
+
+Grace did not agree with him; so she said nothing. In spite of the fact
+that Mrs. Stapleton used cigarettes similar to those which seemed in
+some queer way to be at the bottom of the mystery, she had an intuitive
+feeling that the grief which the banker's wife showed was entirely real.
+
+At half past seven, Grace left the prefecture in a high-powered car,
+furnished by Monsieur Lefevre. Alphonse Valentin was at the wheel. In
+her hand she held a pocket electric searchlight, across the front of
+which had been affixed a circular bit of blue glass.
+
+At ten minutes to eight she arrived at Versailles. She at once ordered
+Valentin to turn and drive back toward Paris at moderate speed. She did
+not take him into her confidence regarding what she proposed to do, but
+kept a keen watch for the car containing Mr. Stapleton.
+
+Her plan had worked. Mr. Stapleton, seeing her signal, had tossed her
+the package of money--she only hoped that the other part of her plan had
+been carried out with equal success.
+
+The other part of the plan had been this: Monsieur Lefevre, who in build
+and general appearance was not unlike Mr. Stapleton, was to follow the
+latter's car in a machine of the same make and general appearance. He
+was to be driven by a chauffeur made up to resemble François
+sufficiently to be mistaken for him in the dim light of early evening.
+He himself was to make such alterations in his appearance and dress as
+would enable him to pass, under a cursory examination, for Stapleton. In
+the bottom of the car two armed men lay concealed.
+
+When the car containing Mr. Stapleton turned back toward Paris, after
+having unwittingly delivered the money to Grace, the Prefect would
+continue on toward Versailles. He would know that the car containing the
+kidnappers was still ahead of him; since, had it not been, it, instead
+of Grace's car, would have signaled Mr. Stapleton.
+
+Grace had started out from Versailles especially early, convinced that
+the kidnappers would not leave there until eight, at least. In this
+assumption she was correct. The car containing the kidnappers was, at
+that moment, creeping toward Paris some two miles in her rear, looking
+everywhere for Mr. Stapleton.
+
+The Prefect pursued his way toward Versailles in anxious expectancy.
+Each moment he thought to see the blue signal flash from the various
+cars which passed him. When it came, his men were to spring up, and at
+once bring the other car to a standstill by firing their guns, heavily
+charged with buckshot, at its wheels. A punctured tire, and the thing
+was done. His men, assisted by the chauffeur, would then overpower the
+occupants of the other car before they could realize what had happened.
+In it they hoped to find the child.
+
+The plan was well conceived; but unfortunately it did not work.
+Whatever the reason, none of the cars which passed the Prefect on his
+way to Versailles displayed the telltale blue light. All seemed but
+peaceable automobilists, intent on reaching Paris and its restaurants as
+quickly as possible. Had his disguise been penetrated? He could not
+believe it. He returned to the Prefecture in great disgust, wondering in
+what way matters had gone wrong.
+
+Grace was waiting for him, an eager smile on her face. "Here is the
+money," she said, placing the package on his desk. "Did you get the
+men?"
+
+"No." The Prefect flung himself into a chair. "They did not signal."
+
+"But why, I wonder?" The failure of her plan was extremely annoying.
+
+"I can think of but one reason. There must have been some way in which
+these fellows knew the Stapleton car when they approached it--some
+signal, perhaps, that I was unable to give."
+
+"But no such signal was mentioned in the instructions I brought to Mr.
+Stapleton. He gave none, as we approached him."
+
+"Did you observe anything peculiar about the appearance of his car,
+anything that might have served as a clue to enable these fellows to
+recognize it, even in the dark, with certainty?"
+
+Grace thought a moment, then her face fell. "There was one thing that I
+noticed as Mr. Stapleton's car came up to us; but I am afraid I failed
+to realize its significance at the time."
+
+"What was it?"
+
+"The electric headlight on the side nearest to me was working very
+badly. In fact, it seemed to be almost out. The other was burning
+brilliantly."
+
+The Prefect sprang to his feet. "Sacré!" he exclaimed. "Of course. The
+thing is as plain as the nose on your face!"
+
+"But who--"
+
+"François! The fellow is in this thing up to his neck. _He_ claims to have
+been asleep when the boy was stolen. _He_ drives the car which brings
+you back, after your abduction. _He_, disguised, steals the box of
+cigarettes. _He_ fixes the lights so that the kidnappers are advised,
+not only beyond any doubt that they are signaling the right car, but
+that all is safe--that Monsieur Stapleton has no detectives or members
+of the police hidden in his tonneau. The thing is perfectly clear.
+Believe me, my child, had there been anyone in that car with Mr.
+Stapleton, those lights would have both been burning with equal
+brightness, as mine were. They did not give me the signal, when they
+passed me, because the lights failed to tell them that all was well."
+
+Grace looked up quickly. "Then, if that is true, François knew that Mr.
+Stapleton had thrown the money into the wrong car."
+
+"Undoubtedly, and by this time, no doubt, his confederates know it as
+well. Naturally the child has not been delivered. We are just where we
+were before."
+
+"You will arrest François at once, I suppose."
+
+"No. It will be useless. By leaving him free, we may learn something. By
+locking him up, with no tangible evidence against him, we accomplish
+nothing at all."
+
+"Then what do you advise?"
+
+"You will return the money to Mr. Stapleton at once. You can tell him,
+if you wish, how it came into your possession. He will be furious, of
+course; but he must understand that the capture of these scoundrels is
+quite as important to the city of Paris as the recovery of his son. We
+have done our best, and failed. We must try again."
+
+"Richard was at the Porte de Versailles," remarked Grace, quietly. "He
+tried to stop my car."
+
+"Yes. I saw him. He is coming here at once."
+
+The girl rose, in nervous haste. "I must go, then. It would be most
+unwise to have him find me here."
+
+There was a quick knock at the door. The Prefect rose, and opened it;
+then turned to Grace with a grim smile. "Your husband is waiting in the
+anteroom," he whispered.
+
+"But--what shall I do?"
+
+"Wait in here." Monsieur Lefevre opened the door which led to his
+private office. "You can hear everything quite plainly. From what you
+tell me, I should not be surprised if he insisted upon your arrest at
+once."
+
+"It isn't fair to him. Poor Richard! I'm afraid he'll never forgive me
+for all this."
+
+"Nonsense! You are engaged in a very laudable attempt to recover Mrs.
+Stapleton's child. So is he. Your interests are identical. Only," he
+paused with a significant smile, "from my standpoint, I should much
+prefer that the credit for the boy's recovery should belong to the
+police of Paris, of which you, for the time being, are one."
+
+Richard Duvall came into the Prefect's office, somewhat ill at ease. The
+room, familiar to him because of the events of the past, reminded him
+forcibly of Grace--who had, indeed been upon his mind constantly for the
+past few days. It was here, in this very room, that she had first told
+him that she loved him--during the exciting pursuit of Victor Girard,
+and the million francs. He gazed about at its familiar aspect, and
+sighed.
+
+"Sit down, my dear Duvall," said the Prefect, shaking hands with him
+warmly. "What, may I ask, brings you to Paris, at the cost of
+interrupting your honeymoon? I had supposed that nothing could be of
+sufficient importance for that. In fact, had I known you would consider
+it for a moment, I should have cabled to you, to give me your assistance
+in a most trying case."
+
+"What case, Monsieur?"
+
+"The mysterious kidnapping of the child of Monsieur Stapleton."
+
+"It is that very case that brings me to Paris. I am in Mr. Stapleton's
+employ."
+
+Monsieur Lefevre affected to be greatly surprised. "Is it possible,
+_mon ami_? That is bad news indeed. This fellow Stapleton no longer has
+confidence in my office. He retains you to do that which he believes I
+shall fail to do. I am sorry, my dear Duvall, that we are on opposite
+sides of the fence."
+
+"But, Monsieur, I did not know that you wanted me. Mr. Stapleton is an
+old friend. I could not refuse to come to his assistance."
+
+Lefevre's eyes twinkled. "Have you made any progress, then, my friend?"
+
+"Yes. Tonight I put in operation a plan whereby I might identify an
+automobile containing the kidnappers, into which Mr. Stapleton had been
+directed to throw a package containing one hundred thousand dollars."
+
+"Indeed. You interest me. And did you succeed in identifying it?"
+
+"I did. I stopped the car, at the Porte de Versailles. I knew it to be
+the one into which the money had been thrown. The car was driven by a
+man named Alphonse Valentin, whom I have every reason to suspect is
+concerned in this affair. Its only other occupant was a woman--whom I
+met last night in Valentin's rooms, and who brought Mr. Stapleton a
+message from the kidnappers. This woman is, I believe, at the bottom of
+the whole thing."
+
+"Indeed. And did you arrest her?"
+
+"No. She claims to be an agent of your office. Vernet, who was at the
+gates at my request, refused to place her and her companion under
+arrest. She got away with Mr. Stapleton's money. I believe, Monsieur
+Lefevre, that you are being made a fool of by a member of your own
+staff."
+
+The Prefect leaned over, and picked up the package containing the money
+which lay upon his desk. "I do not agree with you, my friend. Here is
+Monsieur Stapleton's money."
+
+Duvall started back in his chair, amazed. "Good Lord, Chief, am I losing
+my senses? What is this affair, anyway, a joke?"
+
+"Far from it, Monsieur Duvall. The criminals are still at large. The boy
+is in their hands. We must recover him."
+
+"But--this money--"
+
+"I arranged to get it, in order to prevent Monsieur Stapleton from
+making a fool of himself. I wish to capture these men--not to let them
+blackmail him out of half a million francs."
+
+"Had you not interfered, Monsieur Lefevre, they would have been in my
+hands, by now. I would have had them safely the moment they attempted to
+enter Paris. I knew their car."
+
+The Prefect was filled with curiosity. "How?" he asked.
+
+"My means of a device with which Mr. Stapleton's car was equipped, the
+body of the one into which he threw the money was spattered with red
+paint. I could have identified it anywhere."
+
+"My dear Duvall! I feel that I should beg your pardon. Your plan was
+cleverness itself, and I will admit that, had I not interfered, you
+would in all probability have captured these men. I did not know what
+you had done, of course. Yet in their escape I have one consolation. It
+would have been extremely distasteful to me, to have had Mr. Stapleton
+boast that a private detective in his employ had succeeded, where the
+police of Paris had failed."
+
+"Then it would appear, Monsieur," said Duvall somewhat stiffly, "that we
+are, in this matter at least, in opposition."
+
+"Let us rather say, my friend, in competition." He placed his hand on
+Duvall's shoulder. "You must not blame me, if I feel a pride in my
+office. When you were working for the city of Paris, you, too, felt
+that pride. I am truly sorry that I have not the benefit of your
+services now. However, I think you will admit, _mon ami_, that the young
+woman who is handing this case is no mean adversary." The Prefect
+regarded the detective with a quizzical smile, behind which his eyes
+twinkled merrily.
+
+"Who is this woman?" asked Duvall, quickly.
+
+"Her name is--Goncourt--Estelle Goncourt."
+
+"A Frenchwoman?"
+
+"Partly. I believe her mother was English." The twinkle in his eye
+spread--he smiled upon the detective with expansive good humor. "Why do
+you ask?"
+
+"You will think it strange, perhaps, Monsieur Lefevre, but when I first
+saw Miss Goncourt, she reminded me strongly of my wife."
+
+"Of Grace?"
+
+"Yes. Have you not observed it?"
+
+"Now that you speak of it, perhaps there is something similar in the
+manner--the carriage. But your wife, my dear Duvall, is a blonde, while
+Mademoiselle Goncourt is decidedly a brunette."
+
+"Yes. Of course. But, nevertheless, the resemblance is striking." He
+rose to go. "I hope, Monsieur, that this kidnapped boy may be restored
+to his father very soon. I am anxious to return to America."
+
+"What! Leave Paris so quickly? My dear Duvall, I thought you Americans
+loved our city so well, that you never wanted to leave it."
+
+"Paris is all right, Monsieur; but," he laughed heartily, "I must get
+back to my wife and my farm. I was forced to leave in the very middle of
+my spring plowing."
+
+The Prefect roared. "You--a farmer! Mon Dieu! How droll! Potatoes, I
+suppose, and chickens, and dogs, and pigs--"
+
+"Exactly--and, believe me, Monsieur, they are more to my liking, than
+all the gaieties of Paris. Some day you must make us a visit, and see
+for yourself." He turned toward the door.
+
+"I shall, Duvall, I shall. But first we have to find this boy. What do
+you propose to do next?"
+
+Duvall smiled. "What do you?" he retorted.
+
+"A bottle of champagne, my friend, and a dinner at the Café Royale, that
+we find the child before you do!"
+
+"Done! Now I'll be off. Good night."
+
+The Prefect was still laughing when Grace peeped in from the private
+office, to find that Richard had gone. "I think it's a shame to treat
+him so," she said. "The poor fellow! And he _would_ have gotten the
+kidnappers, if we hadn't interfered."
+
+Monsieur Lefevre picked up the package containing Mr. Stapleton's money
+and placed it carefully in his safe. "Tomorrow you must return it to
+him," he said. "And then, I would suggest that you keep a close watch
+upon Mrs. Stapleton. My men have not been keeping her under
+surveillance. We have had no suspicions of her whatever. She may, if she
+is concerned in this matter, be imprudent enough to attempt to visit the
+child."
+
+"And if not?"
+
+"Then watch François. If nothing comes of your efforts in either
+direction, I fear that we must wait for the kidnappers to make the next
+move. Of course there is Valentin--"
+
+"Valentin is innocent."
+
+"How do you know that?"
+
+"I have watched him. He did everything in his power, tonight, to assist
+me. Had he been in league with the kidnappers, he could, after he knew
+that I had secured the money, easily have driven the car to some quiet
+spot and taken it from me. I was waiting for some such move; but he, as
+you know, did not attempt it. I am sure that he is doing his best to
+assist us."
+
+"In that event, perhaps you can induce him to tell you the secret of the
+box of cigarettes. I feel sure that this knowledge would go far toward
+solving the entire affair."
+
+"I'll have a talk with him tomorrow."
+
+"Good! And now, if you are ready, we will return home at once."
+
+"Dear old Richard!" said Grace, as the Prefect helped her into his
+automobile. "I wish I were with him tonight."
+
+Lefevre smiled, and patted her hand. "So do I, my dear. But, remember,
+you have only to find Mr. Stapleton's child, and you can return to your
+chickens and your cows with the knowledge that you have done both his
+parents and myself an inestimable service."
+
+
+
+
+CHAPTER XI
+
+
+It was close to eight o'clock next evening when Grace Duvall arrived at
+Mr. Stapleton's house with the package containing the money.
+
+She was accompanied, for safety, by two men from the Prefecture, who
+escorted her to the door.
+
+She had paid a previous visit to the house, during the forenoon; but Mr.
+Stapleton was not at home, and she was informed that he would not return
+until evening.
+
+Mrs. Stapleton she saw again; but her talk with the latter resulted in
+nothing. The poor lady was in utter despair, after the fiasco of the
+night before, and spent the day in her rooms, weeping.
+
+It was quite clear to Grace that her grief was very real. She made up
+her mind that, whatever the mystery of the gold-tipped cigarettes, Mrs.
+Stapleton had nothing to do with it. Nor had the chauffeur, Valentin,
+been more communicative. He refused pointblank to explain the presence
+of the cigarettes in his room, or the reason why Mary Lanahan had
+written requesting him to destroy them. He said that it was a matter
+which concerned only the nurse and himself, and assured Grace that an
+answer to her questions would not assist in the least in recovering the
+missing child.
+
+Mr. Stapleton was awaiting her in the library when she entered. The
+Prefect had telephoned him, advising him that the money was safe, and
+would be returned to him at once. Beyond that, he knew nothing, except
+what Duvall had told him the night before. Consequently he was in a
+decidedly bad humor.
+
+Grace laid the money on the table. "Here is your hundred thousand
+dollars, Mr. Stapleton," she said.
+
+The irate banker glared at her. "I cannot thank you for bringing it
+back, Miss," he growled. "Did I not particularly request that the police
+take no steps in the matter?"
+
+"You did, Mr. Stapleton; but we acted for what we thought to be your
+best interests."
+
+"Hang your thoughts about my best interests! I can take care of them.
+If you had let things alone, I'd have my boy back by now."
+
+"And these men, these criminals, who stole him, would be at liberty to
+do the same thing over again tomorrow."
+
+Mr. Stapleton was silent for a moment. "How did the thing happen?" he
+presently asked.
+
+Grace told him. "The real cause of our failure, we believe, lies at the
+door of your chauffeur, François." She explained the reasons for their
+suspicions.
+
+Mr. Stapleton seemed puzzled. "The fellow seems honest enough."
+
+"Where is he now?" Grace inquired.
+
+"He asked permission to visit his people. As I had no use for him this
+evening, I told him he might go."
+
+"Ah! In that event, we may learn something. He is being closely
+watched."
+
+As Grace spoke, a servant entered the room. "There is a gentleman to see
+you, sir," he said to Mr. Stapleton.
+
+"Who is it?"
+
+"He would not give his name. He said his business was urgent."
+
+"Where is he now?"
+
+"In the reception room, sir."
+
+Mr. Stapleton rose. "Excuse me a moment," he said, and went into the
+adjoining room.
+
+The library was separated from the reception room by a short passageway,
+or alcove, in which hung a pair of heavy curtains. Grace sat quietly,
+waiting for Mr. Stapleton to return. Suddenly she realized that she
+could distinctly hear what was going on in the room adjoining. For a
+moment she thought of going into the hall; then a word or two caught her
+attention, and in a moment she was close to the curtains, listening
+intently to a most remarkable conversation.
+
+The man who had asked to see Mr. Stapleton stood in the reception room,
+near a broad window overlooking the street without. He was tall and
+somewhat heavily built; but what at once attracted Grace's attention was
+his heavy black beard. She recognized him at once as the man who had
+broken into Valentin's room to steal the cigarettes, and had later
+driven the car which brought her back to Paris after her abduction.
+
+He was speaking to Mr. Stapleton in a quiet and assured tone, as though
+discussing a topic of no greater importance than the weather.
+
+"Mr. Stapleton," he said, "I have your son in my possession. He is
+quite safe. I gave you an opportunity to have him returned to you last
+night; but you did not avail yourself of it."
+
+"I did my best," exclaimed the astounded banker, mastering his desire to
+take the fellow by the throat.
+
+"That may be; yet my plans were interfered with. You did not carry out
+my instructions."
+
+"I did--to the letter."
+
+The man frowned. "It is useless to discuss the matter now," he growled.
+"I come to give you one more chance. It will be the last--"
+
+"You damned scoundrel!"
+
+The man with the black beard held up his hand. "It will avail nothing,
+Monsieur," he said, calmly, "to excite yourself. If you want back your
+boy, listen to what I have to say."
+
+"Very well. Go ahead."
+
+"First, I want no interference by the police, or by the man Duvall, who
+is acting for you."
+
+Mr. Stapleton drew back in astonishment. "How do you know that Mr.
+Duvall is acting for me?" he said.
+
+"It is my business to know, Monsieur. Let it suffice that I _do_ know.
+If you hope ever to see your child again, you had better listen to what
+I have to say, and carry out my instructions to the letter." His voice
+was harsh, menacing.
+
+Mr. Stapleton directed him by a gesture, to proceed. He was too angry to
+speak.
+
+"Tomorrow night at this hour--eight o'clock--I shall come here, to this
+house, and ask for you. You will hand me a package containing one
+hundred thousand dollars. I will examine the money here, and satisfy
+myself that the amount is correct.
+
+"I shall then leave the house, and walk to the Arc de Triomphe; which,
+as you know, is but a short distance away. At the Arc de Triomphe, I
+shall wait for an automobile, which will stop for me. In that automobile
+I shall drive away. If I get away safely without interference, there
+will be telephoned to your house, within half an hour, the address of
+the place where your boy is to be found. If I do _not_ get away safely,
+that address will _not_ be telephoned to you, and you will not see your
+child alive again. This is your last chance, Monsieur. It is most
+important, I assure you, that nothing should happen to prevent my safe
+departure tomorrow night."
+
+For a moment Grace was undecided as to how she should act. She feared
+greatly, under the circumstances, to make any move which would endanger
+the safety of Mr. Stapleton's child. Yet her duty, as an agent of the
+police, was clear. She must use every effort to effect this man's
+capture, before he left the house.
+
+She knew that she could not reach the street without passing the door of
+the reception room, in which case both Mr. Stapleton and his caller
+would see her. There was nothing to do but telephone. She flew to a
+small alcove room which opened off the rear of the library, in which she
+knew the telephone instrument was located. Once in this small room, she
+closed the door, for fear the others might overhear her, then called up
+the Prefecture. Monsieur Lefevre was out; but she acquainted one of his
+assistants with the circumstances, and requested him to send a man to
+the house at once.
+
+It would take at least ten minutes, perhaps more, for the man from the
+Prefecture to reach the house even though he came by automobile, as he
+no doubt would. What should she do, to keep the man in the reception
+room from leaving before the police should arrive?
+
+The question was solved for her, quite unexpectedly. In opening the
+door of the small room, to re-enter the library, she accidentally struck
+against a chair. The sound aroused both Mr. Stapleton and his visitor.
+The former, who had, in his excitement, completely forgotten Grace's
+presence, appeared at once in the doorway between the two rooms. "Come
+here, Miss Goncourt," he said sternly.
+
+Grace entered the reception room. The man with the black beard eyed her
+keenly. "Ah--a representative of the police, I believe. Our conversation
+has been overheard, then, Monsieur Stapleton?"
+
+The banker was violently angry. He turned to Grace. "You have heard?" he
+demanded.
+
+"Yes."
+
+"Then I insist that you do not interfere in the matter in any way. I
+intend to get my boy back this time, in spite of you all."
+
+Grace made no reply. She saw the man with the black beard eying her
+keenly. "I think, Monsieur, that I had better go," he remarked.
+
+Grace regarded him with a level look. "You cannot leave this house," she
+said. "It is being watched. If you attempt to do so, I will give the
+alarm."
+
+"And for what reason should I stay?" the man inquired calmly.
+
+"I have telephoned to the Prefecture. A man will be here in a few
+minutes, to place you under arrest. I advise you to remain here quietly
+until he arrives."
+
+The kidnapper strolled over to the window which overlooked the Avenue
+Kleber, drew aside the curtain, and looked out. Grace wondered if he was
+making a signal of any sort to confederates outside. He gazed into the
+street intently for a moment, then turned back toward the center of the
+room. "I shall follow your advice, Mademoiselle, and wait," he remarked,
+calmly.
+
+Mr. Stapleton was speechless with rage. He dared not do anything; for he
+knew that he would only lay himself open to a charge of resisting the
+police, and helping a criminal to escape. He sat in his chair, inwardly
+cursing Grace and the entire police force of Paris as well.
+
+None of the three spoke for a considerable time. After what seemed to
+Grace ages, she heard the faint ringing of the doorbell, and presently
+the frightened servant arrived, with the information that a detective
+from the Prefecture was in the hall, and desired to see Mr. Stapleton
+immediately. He had scarcely succeeded in delivering this message, when
+a heavily built man in citizen's clothes shouldered past him into the
+room.
+
+He gazed quickly about. Grace did not remember having ever seen him
+before. "I am from the Prefect of Police," he announced, striding toward
+the kidnapper. "I am here to arrest this man." In a moment the click of
+the handcuffs, as he snapped them upon the wrists of the man with the
+black beard, came to Grace's ears.
+
+The kidnapper smiled pleasantly. "I am quite ready to accompany you, my
+friend," he said.
+
+Mr. Stapleton was regarding the scene in helpless rage. He resented
+bitterly the way in which the police continually interfered with his
+plans to get back his child. In one way, he was glad to feel that the
+guilty man was under arrest; but, if it resulted in the death of the
+missing boy, it would be a tragedy, indeed. He turned to the man with
+the black beard who stood, smiling, near the door. "I hope you will
+understand," he said, "that I have nothing to do with this
+matter--nothing whatever. The presence of this woman here was a pure
+accident. I had forgotten that she was in the next room. I'd be glad
+enough to see you put behind the bars for the rest of your life; but
+not if it is going to prevent me from getting back my child."
+
+The man with the black beard continued to smile pleasantly. "I believe
+you, my friend," he said. "However, there is no harm done. When I return
+tomorrow night--for I shall return, depend upon it, in spite of the
+efforts of this gentleman," he waved his hand lightly toward the man
+from the Prefecture, "I trust that you will have persuaded Monsieur
+Lefevre, and your man Duvall as well, to let me do so in peace. It is
+the only way in which anything can be accomplished--I assure you of
+that." He turned to his captor. "I am ready to accompany you, Monsieur."
+
+The officer started toward the door leading into the hall. He had taken
+but a single step when the servant, with a frightened look upon his
+face, appeared in the doorway. "Mr. Stapleton," he stammered, "there is
+a man here from the office of the Prefect of Police."
+
+Stapleton strode toward the door. "Another?" he exclaimed. "What does
+this mean?"
+
+The man in charge of the kidnapper stepped forward, speaking in a quick,
+low tone. "Leave the matter to me, Monsieur," he whispered. "This
+fellow who has just arrived is an impostor, a confederate. He pretends
+to be an agent of the police, in order to rescue his comrade, who has
+undoubtedly signaled to him from the window. Be good enough to step into
+that room," he pointed to the library, "and let me deal with him."
+
+Mr. Stapleton hesitated. "What do you propose to do?" he asked.
+
+"Quick!" said the other, offering no explanations. "He will be here at
+once." He turned to the astonished servant. "Bring the man in."
+
+The puzzled banker moved toward the adjoining room. "You will accompany
+him, please," the Prefect's man said to Grace. "There may be danger."
+
+"I am not afraid, Monsieur," replied Grace, who did not entirely like
+the way things were going.
+
+The man, however, paid no attention to her remonstrances. "Go--at once,
+I command you, in the name of the law!"
+
+She hesitated no longer, but followed Mr. Stapleton into the library. As
+she did so, the new arrival entered the reception room.
+
+The man with the black beard stood to one side of the doorway. His
+captor advanced toward the newcomer. "I have him here," he exclaimed,
+pointing to the kidnapper, "safely ironed."
+
+"Who are you?" curtly inquired the man who had just entered the room.
+
+"A private detective. Here is your man. Let us get him out of here at
+once."
+
+The official made no reply, but stepped quickly up to the man with the
+black beard. "Come along with me," he said, roughly, and placed his hand
+upon the other's arm.
+
+As he did so, the kidnapper shook his wrists briskly. The handcuffs fell
+clattering to the floor. Without a word he threw his powerful arms about
+the neck of the astonished official, and throttled him into instant
+silence. His companion, no less quick, whipped out a handkerchief, and
+knotted it about the official's mouth. He was unable to utter a sound.
+
+The whole thing was so quickly done that Grace, who was watching the
+room through the curtains in the doorway, had barely time to utter a
+cry, before the newcomer was lying helpless and silent upon the floor,
+choked into insensibility; while the two men, quite evidently
+confederates, made ready to go.
+
+The black-bearded fellow quickly replaced the handcuffs upon his own
+wrists. "Quick, Ramond," he cried. "Let us get out at once."
+
+Grace was by this time in the room. She knew that she must in some way
+prevent these men from escaping. But how--how? They glared at her
+ominously. The younger man drew a revolver. Before any of them could
+speak, the servant appeared in the doorway for the third time. His face
+was pale as death. His knees knocked together from terror as he beheld
+the gleaming revolver, the man lying upon the floor.
+
+"Monsieur Duvall is here!" he gasped, and stood silent.
+
+The man on the floor, recovering his senses, began to struggle to his
+feet. As he did so, Duvall pushed his way past the frightened servant
+and strode into the room.
+
+"Quick, Monsieur Duvall!" the fellow with the revolver cried. "I am from
+the Prefecture. I have one of the kidnappers in irons. The other," he
+pointed to the struggling man on the floor, "is about to escape me. Give
+me your assistance at once!"
+
+Grace was so astounded by the sudden entrance of her husband, as well as
+by the kidnapper's words, that for a moment she remained speechless.
+Duvall bent over the man upon the floor and seized him by the throat.
+
+"Richard! Richard!" Grace screamed, forgetful of Monsieur Lefevre and
+her own disguise. "Look out!"
+
+Almost before the words had left her lips, the man with the revolver
+brought it down with a dull thud upon Duvall's head as he bent over the
+prostrate man; then, grasping his companion by the arm, he rushed from
+the room.
+
+"Richard! Richard!" screamed Grace, throwing her arms about the
+senseless body of her husband.
+
+Mr. Stapleton, who had entered the room, regarded her in amazement.
+"What are you doing?" he exclaimed.
+
+Grace rose, her face white with suffering. "A doctor, quick! He is hurt!
+My God--don't you see? He is hurt!" As she spoke, she fell back,
+fainting, to the floor.
+
+
+
+
+CHAPTER XII
+
+
+When Richard Duvall returned to consciousness, an hour later, he lay
+upon a couch in Mr. Stapleton's library. A doctor, hastily summoned, was
+bending over him. Mr. Stapleton sat grimly in an arm chair. There was no
+one else in the room.
+
+"My wife! Is she here?" the detective cried, as he tried to rise.
+
+The doctor pushed him gently back. "Compose yourself, Monsieur," he said
+in a soothing voice. "You are not badly hurt. Merely stunned for the
+moment. A slight cut--that is all. You will be quite yourself again in
+half an hour."
+
+"But my wife!" He gazed eagerly about the room.
+
+"What do you mean, Duvall?" inquired Mr. Stapleton, calmly. "Why do you
+think your wife is here?"
+
+"A trace of delirium. He will be all right in a few moments. Very usual
+in such cases," the doctor whispered.
+
+"I heard her voice. She called to me by name, just as that fellow struck
+me."
+
+"My dear sir, your mind is wandering. Compose yourself, I beg." The
+doctor attempted to press his patient back upon the pillows.
+
+Duvall passed his hand over his forehead, completely bewildered. "I
+could have sworn I heard her voice," he cried.
+
+"It was Miss Goncourt, the young woman from the Prefecture, that you
+heard, Duvall," remarked Mr. Stapleton quietly. He did not tell the
+detective that Grace, on recovering from her faint, and learning from
+the doctor that Richard's wound was a superficial one only, and not at
+all serious, had sworn them both to secrecy, on the plea that the matter
+was a purely private one, and likely to cause her great unhappiness if
+divulged. Mr. Stapleton had agreed, but had done so only upon her
+agreeing not to acquaint the police with his plans for the following
+night.
+
+She had suddenly conceived a violent animosity toward these fellows who
+had not only baffled both her husband and herself, but had made the
+former a victim of a dangerous assault. She was determined to go to
+work in desperate earnest, to capture them, or locate the child, before
+the following evening. She had promised Mr. Stapleton not to acquaint
+Monsieur Lefevre with the plan for returning the child which the man
+with the black beard had proposed. The situation put her on her mettle.
+She determined to get at the bottom of the whole affair before another
+twenty-four hours had passed. Upon leaving the house she called a
+taxicab, and at once ordered the chauffeur to drive her to the point on
+the Versailles road where, according to Valentin, she had been placed in
+the automobile after her interview with the kidnappers. Here, she
+believed, lay the starting point of the whole mysterious affair.
+
+Duvall, his consciousness returning, insisted upon getting up from the
+couch, and going to work with equal determination. The way in which he
+had been checkmated, in the whole affair, roused him, as well, to
+desperation. His professional skill, upon which the banker had set such
+great store, seemed to have deserted him. He felt humiliated, ashamed.
+In three days, he had accomplished nothing whatever. It was galling in
+the extreme.
+
+Mr. Stapleton's explanations of his hallucination regarding his wife he
+accepted as true. The resemblance which Miss Goncourt bore to Grace,
+together with his constant thoughts of her, were, he argued, no doubt
+responsible for it. The blow upon the head made his recollections of the
+moments immediately preceding and following the assault extremely hazy.
+He put the matter out of his mind, and set to work with renewed energy.
+
+So far, it seemed, he had met with but a single clue of any
+importance,--the cigarette with the gold tip which he had found in the
+Bois de Boulogne. He determined to follow this clue until he arrived at
+some definite result.
+
+As soon as the doctor had departed after dressing the wound in his head,
+Duvall took a stiff drink of brandy, and, sitting down with Mr.
+Stapleton at the latter's desk, began to reconstruct, as far as he
+could, all the details of the kidnapping. He spoke his thoughts aloud,
+taking Mr. Stapleton into his confidence, since in this way he could
+most readily get his ideas into concrete form.
+
+"Mr. Stapleton, I am, I confess, greatly humiliated at the progress, or
+lack of progress, which I have made in this case so far. I have made up
+my mind, however, to get these fellows, if it takes me the rest of the
+summer."
+
+"You will have to work more quickly than that, Mr. Duvall," observed the
+banker coldly. "I have made arrangements to recover my child by tomorrow
+night."
+
+"You are going to buy these rascals off, then?"
+
+"Yes."
+
+"How?"
+
+"I decline to say. I've had enough interference with my plans already.
+Neither you nor the police have accomplished anything. Miss Goncourt
+knows what I propose to do; but she has given me her word not to
+interfere. If you are to accomplish anything, it must be before eight
+o'clock tomorrow night."
+
+"Very well. I will make my plans accordingly."
+
+"What do you propose to do?"
+
+"That I cannot say, at the moment. I think, however, that I shall first
+try to find out who it is that smokes these gold-tipped cigarettes." He
+drew the fragment of cigarette which he had found from his pocket, and
+placing it on the desk before him regarded it critically.
+
+Mr. Stapleton gave a grunt. "What are they, Exquisites?"
+
+"Yes. How did you know?"
+
+The banker laughed. "Easy enough. My wife smokes them."
+
+The detective looked up quickly. "Indeed! Brings them from America with
+her, I suppose."
+
+"Yes."
+
+Duvall began mentally to check off, in his mind, the various persons who
+might have used the cigarette which lay before him. Valentin, he now
+believed, was out of the question. His presence in the automobile, with
+Grace, the night before, indicated that he had nothing to do with the
+kidnappers.
+
+There remained Mrs. Stapleton. Duvall had talked with her--seen her
+grief. He was too shrewd a judge of human nature to think for a moment
+that it was assumed.
+
+Who else? Suddenly an idea flashed into his mind. He wondered that he
+had not thought of it before. The nurse! He recalled vividly the marks
+he had observed on the dresser in the woman's room in New York.
+
+"Is Mary Lanahan in the house?" he inquired of Stapleton.
+
+"Yes. Why?"
+
+"Kindly have her come here."
+
+Mr. Stapleton pressed a button on his desk in silence. In a few moments,
+the nurse had been brought to the room by one of the other servants. She
+was haggard with grief and fear.
+
+Duvall requested her to be seated, and began to ask her a number of
+apparently unimportant questions regarding the kidnapping.
+
+She answered them frankly enough, although it was clear that she was
+very ill at ease.
+
+Presently Duvall got up, and, calling Mr. Stapleton to one side, asked
+him, in a low tone, to detain the nurse in the library for a few
+moments. He wished to search her room.
+
+"But it has already been thoroughly searched by the police."
+
+"I know. But I must search it again. It will require but a few moments."
+
+Stapleton nodded. "I will wait for you here, Mr. Duvall," he said.
+"Mary, you will wait, as well."
+
+The nurse's room was on the third floor, in a rear building. Duvall
+found it, after some slight difficulty, with the assistance of one of
+the other servants.
+
+He seemed, on entering the room, to have but one object in view. He went
+at once to the mantel, and, taking from it the two small bottle-shaped
+vases which stood upon it, shook them both vigorously. A faint rattling
+sound came from the second. He turned it upside down upon the palm of
+his hand, and there tumbled out a quantity of ashes, and the butts of
+several partly smoked cigarettes. With a quiet smile he replaced them in
+the vase, and returned to the library.
+
+"Mary, you may go now," he said.
+
+When the woman had gone, he turned to Mr. Stapleton. "It was Mary
+Lanahan herself who smoked the cigarette which I found in the grass," he
+said.
+
+"Well, what of it?" The matter seemed to the banker to be utterly
+without significance.
+
+"She had, no doubt, stolen them from Mrs. Stapleton."
+
+"Very likely. Not a very serious matter, however."
+
+"No. But the question now arises, Why did she turn the box over to
+Valentin, and subsequently ask him to destroy it?"
+
+"I cannot imagine."
+
+"And why, later, were these cigarettes stolen from Valentin, as I
+understand they were?"
+
+"It's too much for me. What do you make of it?"
+
+"I have a theory, Mr. Stapleton; but I cannot say just what it is--yet.
+By the way, where is your man, François, tonight?"
+
+"He is visiting his people, somewhere in the suburbs."
+
+"Ah! Then I would like to search his room, as well."
+
+"Go ahead. You will find nothing, I fear. The police have gone over it
+with a fine-tooth comb." He rose. "Come along, I'll go with you."
+
+The room occupied by the chauffeur was at the very top of the house,
+with two windows opening through the slanting mansard roof. One of
+these, Duvall noted, commanded a view over the houses adjoining toward
+the north, beyond which could be seen the Avenue du Bois de Boulogne. A
+second window, toward the south, commanded an extensive view toward
+Passy.
+
+Mr. Stapleton, puffing because of the unaccustomed stairs, sat down upon
+the bed. "I cannot imagine what you hope to find here, Duvall," he
+grumbled.
+
+The detective made no reply, but began a systematic inspection of the
+room. One of the first objects which attracted his attention was an
+ordinary electric searchlight, of the pocket variety, lying on the man's
+dresser. He picked it up, and examined it carefully.
+
+"I got it for François," observed Mr. Stapleton, "so that he could
+examine the car, at night, in case of any accident or repair."
+
+"Of course. Very useful, too. But why, I wonder, does he keep it here in
+his room, instead of in the garage?"
+
+"Possibly to light himself up the stairs, at night," said Stapleton.
+
+"Then I should think he would have it with him," remarked Duvall, dryly.
+"Wouldn't be of much use to him tonight, for instance." He was about to
+put the thing down, when his attention was attracted by two objects,
+hanging one on each side of the dresser, from its two uprights. They
+were apparently Christmas tree ornaments, made of thin glass, and they
+hung from the back of the dresser by means of two bits of ribbon.
+
+They seemed at first glance to be merely souvenirs of some party, some
+entertainment, which the chauffeur had preserved as mementos of the
+occasion. They were shaped like little cups, with a paper fringe about
+the top, to which the gay ribbons were attached. Duvall had seen such
+ornaments often before, at Christmas time. They were intended to be hung
+from the tree by their ribbons, and were filled with small candies or
+bonbons. He had almost passed them by, when something in their colors
+caused him to pause. One was a deep blue, the other an equally deep red.
+He examined the wooden uprights of the dresser with great care. All
+along the top of the dresser at its back was a heavy coating of dust.
+The top of the uprights, over which the loops of ribbon which supported
+the little baskets had been passed, contained no dust whatever.
+
+Evidently the baskets had been taken down, and that too quite recently.
+For what purpose? he wondered. Suddenly he had an inspiration. He took
+down the little blue basket, and quickly placed it over the end of the
+searchlight. It fitted perfectly, the paper collar at its top holding
+the glass hemisphere snugly in place.
+
+Mr. Stapleton was watching Duvall without particular interest. Suddenly
+the detective pointed the searchlight toward him and pressed the button
+which threw on the current. Mr. Stapleton started back, as his face was
+flooded with a beam of brilliant blue light.
+
+Duvall replaced the little basket in the same position in which he had
+found it, and laid the searchlight upon the dresser. "Rather neat, isn't
+it?" he exclaimed.
+
+"What do you make of it?" asked the banker.
+
+"Your man François evidently is in the habit of making signals," the
+detective replied, laughing. He was beginning to feel hopeful. The
+search of the two rooms was bearing fruit.
+
+For the next half-hour, Duvall went over the contents of the chauffeur's
+room with the utmost care. He removed and replaced, just as he found
+them, the contents of the dresser drawers. He opened a small wooden
+trunk which stood at one side of the room, and examined its contents
+minutely. He explored the closet, looked behind the pictures, sounded
+the walls. Nothing further of an unusual nature rewarded his efforts.
+Still he seemed unsatisfied.
+
+"What more can you hope to find, Mr. Duvall?" inquired the banker, who
+had begun to find the proceedings tiresome.
+
+The detective stood in the center of the room, and glanced about in some
+perplexity. "I had hoped to find one thing more," he said; "but I am
+afraid it isn't here."
+
+Suddenly he strode over to the mantel, upon which stood a small
+nickel-plated alarm clock of American make.
+
+"This clock doesn't seem to be going," he remarked, then whipped out his
+magnifying glass and carefully studied the brass handle which projected
+from the back, by which it was wound up. "It hasn't been wound for
+several days, either. The back is covered with dust." He picked up the
+clock and tried to wind it; but the handle resisted his efforts.
+
+In an instant he took out his knife, and a moment later was removing the
+screws which held the metal back of the clock in place.
+
+Mr. Stapleton watched him curiously. Duvall's methods savored, to him,
+of the accepted sleuth of fiction. He took little stock in the tiny
+clues upon which the whole modern science of criminology is built.
+
+In a few moments the detective had removed the screws and lifted out the
+rear plate of the clock. As he did so, he gave a grunt of satisfaction.
+A small pasteboard box fell out upon the mantel.
+
+"What is it?" asked Stapleton.
+
+"The box of cigarettes," remarked Duvall, as he opened it. "There are
+three missing. I shall take a fourth." He selected one of the
+paper-covered tubes, placed it within his pocketbook, then thrust the
+box back into the clock, and rapidly replaced the metal plate.
+
+"I don't think there is anything further to be done here, Mr.
+Stapleton," he remarked. "I think I'll be getting along to my room.
+Tomorrow I shall be quite busy."
+
+He stopped for a moment, on his way out, to glance from the window which
+faced toward the north. Between the buildings and trees ran the Avenue
+du Bois de Boulogne, its course illuminated by many street lamps, and
+the flashing lights of passing motor cars. Duvall gazed intently at the
+scene before him for a few moments, then turned to the door, and,
+accompanied by Mr. Stapleton, descended the stairs.
+
+As he was about to leave the house, the banker, who evidently had
+something on his mind, stopped him.
+
+"Mr. Duvall," he said, earnestly, "I would like very much to know what
+you intend to do."
+
+"I'm going to catch these fellows, if I possibly can," the detective
+replied, earnestly.
+
+"What steps do you propose to take?"
+
+"I cannot exactly say--yet. Why do you ask?"
+
+"I'll tell you. The fellow who was here tonight, the one with the black
+beard, is coming to see me tomorrow night, at eight o'clock. I cannot
+tell you more than that. I did not intend to tell you that much--but I
+am obliged to do so."
+
+"Obliged! Why?"
+
+"Because I want your promise that you will make no attempt to stop him.
+If I had said nothing, you might have watched the house, and, upon
+recognizing the fellow as the one who was here tonight, have placed him
+under arrest. I want you to do nothing to interfere with either his
+coming or his going. He will be safe, after he once leaves the Arc de
+Triomphe in his automobile."
+
+"But the police?"
+
+"They know nothing of the matter. Miss Goncourt has given me her word to
+remain silent. She has even agreed to have the men on watch about the
+house withdrawn. Both you and the police may do your best to catch this
+man, after I have carried out my compact with him; but until then I
+want you to keep your hands off."
+
+Duvall was silent for a moment. "Very well, Mr. Stapleton, I shall do as
+you say. In fact, to assure you that I am carrying out your wishes, I
+will agree to remain here with you, at the house, throughout the
+evening."
+
+"Good! I shall expect you. Good night."
+
+"Good night." Duvall left the house, and went at once to his hotel.
+
+Here, a few moments later, he seated himself in an easy chair, and
+taking from his pocket the cigarette which he had secured in the
+chauffeur's room, regarded it critically.
+
+After some little time, he took a match from a box upon a nearby table,
+and, placing the gold tip of the cigarette between his lips, carefully
+lit it.
+
+He drew the smoke into his lungs, inhaling it deeply. Once--twice--three
+times he repeated the operation, then threw himself back into his chair,
+and, closing his eyes, sat buried in thought. In his preoccupation, he
+allowed the end of the cigarette to fall unheeded to the floor.
+
+After many minutes he opened his eyes and started up. "I've got it!" he
+cried, and, picking up the half-burned cigarette from the floor, threw
+it carelessly into the fireplace.
+
+Then he sat down at his table, drew out a sheet of paper and a map of
+the city of Paris, and began to make a series of drawings and
+calculations that occupied him far into the night.
+
+
+
+
+CHAPTER XIII
+
+
+It was nearly ten o'clock when the taxicab containing Grace Duvall
+stopped alongside the road, at a point some four miles beyond the city,
+in the direction of Versailles. She had been unable to give the driver
+the exact location at which she desired to be put down, but had directed
+him to drive on until she told him to stop.
+
+The spot was quite familiar to her, owing to the hours she had spent in
+the vicinity with the searching party the day before.
+
+The taxicab driver seemed rather surprised to see her alight at this
+somewhat lonely spot; but he shrugged his shoulders with true Parisian
+indifference, pocketed the tip she gave him, and drove rapidly off in
+the darkness.
+
+Left to herself by the roadside, Grace began to fear that she had, after
+all, done a rather foolish thing. Now that she was here, she hardly knew
+how to begin.
+
+All about her she saw the dark outlines of cottages among the trees,
+with here and there a straggling light which betokened some household
+late in getting to bed. The country people in this vicinity--growers of
+flowers and vegetables or dairymen for the most part--were asleep with
+their cows about the time that Paris began to dine.
+
+Occasionally the silence about her was broken by the mournful howling of
+a dog; but otherwise all was still.
+
+The night was cloudless, and the lightening of the sky toward the east
+told her that before long a moon would rise above the trees.
+
+Near the road she found a little rustic bench, and upon this she sat
+down to think.
+
+The howling of the dog had suggested to her mind a possible clue to the
+house within which Mr. Stapleton's boy had been, for a time at least,
+confined. She could remember nothing of the garden, and but little of
+the room in which she had been confined; but the dog, playing upon the
+grass with the child, had fixed itself in her memory. She recollected
+distinctly that he was a poodle, mostly black, with fine curling hair,
+like astrakhan fur, and a pointed nose.
+
+There were many dogs of this sort, she well knew, and yet there was one
+peculiarity which had impressed itself upon her memory, which would
+inevitably serve to identify this particular dog, should she ever see
+him again. His long and bushy tail, black for the most part like the
+rest of his body, terminated in a plume of white hair.
+
+It was a most unusual marking in a French poodle. She had never seen it
+before, and she was a great lover of dogs, and knew them thoroughly. It
+was this fact, no doubt, which had caused her to notice the animal, at a
+time when her mind was filled with matters of vastly greater importance.
+
+She had sought carefully for such a dog, on the occasion of the previous
+search, but had not found him. The tale about the escaped cobra had
+caused the country folk to lock up their pets without loss of time.
+
+Now she hoped to find this dog, and through him discover the location of
+the house in which she had been confined. After that--well, she would do
+the best she could.
+
+It occurred to her that she was not at all likely to discover the
+whereabouts of the black poodle by sitting here on a bench; yet she
+dared not start out until the moon had risen sufficiently high to light
+up her way.
+
+In about an hour, the rim of the golden disk showed itself above the
+treetops, and a little later the black shadows about her began to grow
+luminous, and resolve themselves into white-walled cottages, hedges, and
+outbuildings of various sorts.
+
+A narrow lane ran off from the main road, bordered on each side by
+lindens and poplars.
+
+Along this lane the houses of the little hamlet were set, some near the
+road, others quite a distance back. She rose, and began to walk slowly
+along the lane.
+
+As she had expected, dogs of various sorts and sizes, to judge by their
+voices, began barking as soon as she came opposite the first house. A
+small fox terrier ran through the gateway of a garden, yelping sharply.
+The deep-toned baying of a hound sounded farther up the street. A small
+white poodle, and a black one of the same size, ran after her, as she
+went along, making friendly attempts to play. The one she sought,
+however, seemed nowhere in evidence.
+
+The lane ascended a gently sloping hill, at the top of which stood a
+house, somewhat larger than the others, whose outbuildings and pastures
+proclaimed it to be a dairy farm. There was a hedge of roses along the
+roadside, and a little wooden gate.
+
+Grace heard a sharp bark on the other side of the gate as she passed it,
+and, stopping, glanced over. In the shadow stood a black poodle; but
+whether his tail showed the markings for which she sought she was unable
+to tell on account of the darkness. She gave the gate a gentle push, and
+it slowly opened. The dog ran out into the road. As he crossed a patch
+of moonlight, she saw that her search was ended. This, she was
+convinced, was the dog--and the house!
+
+Her next problem was how to get inside. Try as she would, she could
+think of no excuse which would adequately account for her presence in
+this little frequented locality at such a time of night. That the
+occupants of the house had long ago retired was evidenced by the
+blackness of the windows, the silence which brooded over the whole
+place.
+
+She looked about her. Just across the lane from the little gate a
+building loomed formless against a shadowy clump of trees. She went
+over to it, and found that it was a small shed. The door stood open.
+Inside stood a tumbledown old wagon, dust covered, and quite evidently
+unused for a long time. The shelter of the shed seemed grateful--as
+though she had arrived somewhere, instead of being a wanderer in the
+night.
+
+There seemed nothing to do, now, but wait for daylight. She climbed into
+the creaking wagon and sat upon the seat. There was a back to it, which,
+like the seat, was covered with old and torn velveteen. She leaned back
+in the shadow and closed her eyes. Her walk, the night air, had made her
+tired. In the distance she heard, after a long time, the faint booming
+of a bell. She looked at her watch. It was midnight.
+
+The next thing that Grace remembered was the loud barking of a dog. She
+sat up, feeling stiff and cold. Her neck and left shoulder ached
+painfully. A glance through the open door of the shed told her that it
+was still night; but there was a gray radiance in the air, a soft pale
+light, that betokened the coming of dawn.
+
+She crept stiffly down from the wagon, and again consulted her watch. It
+marked the hour of four. Through a dusty window in the side of the shed
+she saw the eastern sky, rose streaked and bright, heralding the sun.
+
+As the light increased, she saw the dog that had disturbed her sleep
+running about on the grass in front of the house opposite. The house
+seemed much nearer, in the daylight, than it had appeared at night. She
+examined the dog closely. The white tip of his tail, waving gaily in the
+morning light, showed her that it was the one she had sought.
+
+She crouched in the dim shadow of the half-open door and watched the
+scene before her. There was a man, moving about among the small
+buildings to the right. She heard him performing some task--she could
+not at first make out what. Presently the lowing of cattle, the rattle
+of a bucket, as it was drawn up by a creaking windlass, told her that
+the man was tending his cows.
+
+Quite half an hour later she saw him going toward the house, a pail,
+evidently well filled, in each hand.
+
+Then ensued another long silence. The curling wisp of smoke from the
+chimney of the cottage indicated breakfast, and Grace suddenly realized
+that she felt cold, and hungry. For the first time in her life she
+realized how important one's breakfast is, in beginning the day.
+
+Presently the man reappeared and went toward a small building which
+Grace took to be the barn. She could see him clearly now; for the sun
+had risen above the trees and lit up the whole scene brilliantly. He was
+a small, wizened man, with gray hair and a slight stoop. She was quite
+certain that she had never seen him before.
+
+He went to the barn, and she saw that he was engaged in harnessing a
+horse, which he presently attached to a farm wagon. She noted the wagon
+particularly. It was a low two-wheeled affair, with a dingy canvas top.
+A large patch in the canvas showed yellow-white in the sunlight. The
+horse was white.
+
+In a little while the man began to put in the cart a variety of objects
+which he brought from the barn. They appeared to be baskets of
+vegetables or fruit, and cans of milk. Presently he stopped, and went
+toward the house. In a few minutes he returned. This time a woman was
+with him. They carried between them a large wicker basket, which
+appeared to be quite heavy. There was a top on the basket. Grace
+wondered if it could be filled with laundry.
+
+The couple placed the basket in the wagon, putting it in from the front,
+so that it occupied a position close beside the driver. In getting it up
+over the wheel the woman let her end of it slip, and the man cursed her
+with such sudden sharpness that Grace was startled and crouched back
+into the shed. She wondered what the basket could contain, that made the
+man so careful, and the thought came to her, might it not be Mr.
+Stapleton's boy?
+
+The idea possessed her completely. As the man drove out into the lane,
+and rattled down the hill toward the main road, she suddenly realized
+that she must follow; yet how could she hope to do so, on foot? The
+woman had gone back into the house. Regardless of consequences, Grace
+ran out into the lane, and after the wagon at full speed.
+
+When she reached the main road the vehicle had already turned into it
+and was some distance away, headed for Paris, at a speed which, slow for
+a horse, was still much faster than she could possibly walk.
+
+She looked up and down the road helplessly. There were several other
+wagons approaching, all going in the same direction--cityward. She
+realized that they were country people, farmers, taking their vegetables
+and flowers to the markets.
+
+The first one to reach her was driven by a buxom-looking young woman,
+wearing a plaid shawl. Grace hailed her. "Will you be so good, Madame,
+as to take me to Paris?"
+
+The woman glanced at her shrewdly. "I have a heavy load, Mademoiselle,"
+she replied. Her voice was cold, uninterested.
+
+"I will pay you five francs--"
+
+The words had barely left Grace's lips, before the woman had pulled up
+her horse. "Five francs, Mademoiselle? That is another matter. Get in."
+
+Grace clambered up beside the woman and glanced down the road ahead. The
+canvas-covered wagon was still in sight--mounting a hill some three or
+four hundred yards ahead.
+
+The woman looked at her curiously, noting her dress, her hands, her
+shoes. "You are not of the country, Mademoiselle," she remarked,
+pleasantly.
+
+"No. I belong in Paris." She turned to her companion. "I should like to
+return there as quickly as possible."
+
+"My Susette does not care to go above a walk," the woman remarked,
+gazing at her horse, plodding along with mechanical steps, as though
+utterly unconcerned as to whether or not they ever reached Paris. The
+wagon ahead was now out of sight, over the brow of the hill.
+
+"Would you like to make a louis?" Grace took a gold piece from her purse
+and held it in the sunlight. It glistened brightly.
+
+The woman drew back, regarding her companion suspiciously. "A louis? Who
+would not? What do you mean, Mademoiselle?"
+
+"There is a wagon ahead of us, a canvas-covered wagon, with a white
+horse. I am following it. If you will keep that wagon in sight until we
+get to Paris, I will give you this louis."
+
+She turned the gold piece about, making it sparkle in the sun. The woman
+glanced first at her face, then more carefully at the coin, then,
+reaching over, took it in her fingers, and raised it to her mouth. Grace
+wondered what she was about to do. In a moment she had sunk her teeth
+into it, then returned it to her companion. "It shall be as you say,
+Mademoiselle," she exclaimed as she pulled in the reins. "Allons,
+Susette!"
+
+The horse, evidently awakened from his morning dreams, started forward
+with a suddenness which almost precipitated Grace from her seat. The
+trees along the roadside began to fly past them. In ten minutes they
+were close behind the canvas-covered wagon, now moving along at a brisk
+pace.
+
+When they reached the fortifications, the two wagons were separated by
+not more than a dozen feet. Grace's companion glanced at her sharply.
+"From here I go to Grennelle, Mademoiselle," she exclaimed.
+
+Grace looked at the wagon ahead. "Follow it, please," she said. "I will
+give you another five francs."
+
+The woman obeyed in silence. The wagon in front of them headed off
+toward the northwest, going in the direction of Passy. Before a great
+while it crossed the Pont de Passy, turned into the Rue Nicolo, and came
+to a stop before a small brick house, standing in a little garden.
+
+Grace jumped down at the corner, after giving the woman the louis and
+the additional five francs. "Thank you," she said, and started slowly up
+the street.
+
+The wagon with the canvas cover stood quietly alongside the curb. The
+old man who drove it had approached the door of the house, and was
+ringing the bell.
+
+Presently one of the windows on the top floor was thrown open, and a
+man's head was thrust out. Grace could not see his face clearly. He
+looked down at the man at the door, who at the same time looked up. The
+window was instantly closed, and a few moments later the door of the
+house opened and the man came out.
+
+He stood talking with the driver in low tones for a few moments. Grace
+had walked on up the street, fearing to attract attention. Looking back,
+she saw that the two men were gazing after her. She dared not turn her
+head again, but at the next corner turned into a cross street. Then she
+stopped, and cautiously peered around the corner. The two men had gone
+to the wagon and were lifting out the large basket. A few moments later
+they disappeared with it into the house.
+
+After a time, the old man returned with the basket in his hands. From
+the way he carried it Grace could see that it was empty. He tossed it
+carelessly into the wagon, mounted the seat, and drove off.
+
+Grace looked at her watch. It was half past seven. She felt cold and
+hungry, and determined to get something to eat at once. A little pastry
+cook's shop and restaurant on the opposite side of the street attracted
+her attention, and she crossed over, entered, and ordered rolls and
+coffee. She could see the windows of the house into which the two men
+had carried the basket, from where she sat.
+
+She scarcely knew what to do next. It seemed almost certain that Mr.
+Stapleton's child was in the house across the way, and yet--it was
+merely an intuition, a guess, which might turn out to be entirely wrong.
+Yet she feared to go away, not knowing at what moment the child, if he
+was indeed there, might be taken elsewhere, and the clue hopelessly
+lost.
+
+She finished her rolls and coffee, taking as much time to consume them
+as she could. She had just made up her mind to go, when the door of the
+house across the street opened, and a man came out. He was dark, and
+heavily built, and dressed in the costume affected by artists. He headed
+directly for the pastry shop, and Grace realized that he was about to
+enter it.
+
+She turned her face away, fearing lest he might have noticed her, as she
+walked up the street. He did not even glance in her direction, however,
+but went at once to a counter at the rear of the place.
+
+The proprietor came up to him with a smile, rubbing his hands together
+cheerily. "Ah! Monsieur Durand. Up early this morning, I see. What can I
+do for you?"
+
+She did not catch the other's reply, nor did she dare to glance at his
+face. She shrank back into her corner, and, picking up a newspaper which
+lay in the window sill, began to read.
+
+The new customer remained but a few moments. When he left, Grace saw
+that he carried a large paper bag with him, which appeared to contain
+rolls or bread.
+
+He again entered the house, but this time remained inside but a few
+moments. A little later she left the shop, and watched him as he
+disappeared down the street.
+
+For half an hour she walked about, wondering whether she should
+telephone Monsieur Lefevre now, or wait until she had made certain that
+the whole affair was, after all, not a wild goose chase. Suddenly she
+was seized with a new determination. She went boldly up to the house,
+and rang the bell.
+
+In a few moments a sleepy-looking maid opened the door, eying Grace with
+lazy indifference.
+
+"I wish to see Monsieur Durand," the latter said.
+
+"He's out."
+
+"Then I must wait. I am a model. He instructed me to come at eight
+o'clock, and to wait until he returned."
+
+The girl shrugged her shoulders, and pointed to the stairs. "Top floor
+front," she grumbled, and turned away.
+
+Grace lost no time in getting up the stairs. To her surprise, the door
+of the studio, upon which was a card bearing Monsieur Durand's name, was
+unlocked. She pushed her way boldly in, and looked about. The room was
+scantily furnished, and contained little besides a couple of modeling
+stands, several large plaster figures and casts, two chairs, and a
+couch, evidently used as a bed. At the rear of the room was a closet.
+She turned to it and threw it open. It contained only an assortment of
+clothes.
+
+She felt completely baffled. There was no possible place, here, in which
+the child she was seeking could be hidden. Evidently she had been on
+the wrong track. And yet--what had the wicker basket contained?
+
+Suddenly she stopped, quivering with excitement. From somewhere in the
+room--she could not tell where--there came a low sobbing sound, as of a
+child, crying to itself. It vibrated throughout the room, at one moment
+close to her ears, the next far off, intangible, like a whispered echo.
+She stood, listening, every nerve tense with excitement, and still that
+low sobbing went on, coming from nowhere, evanescent as a dream.
+
+The thing seemed unreal, horrifying. She gazed about helpless. Then she
+heard the front door of the house suddenly slam, followed by the sound
+of heavy footsteps on the stairs.
+
+
+
+
+CHAPTER XIV.
+
+
+Richard Duvall rose, the following day, with a less troubled mind than
+at any time since his arrival in Paris.
+
+His calculations of the night before had brought him to a definite
+conclusion.
+
+After breakfasting in the café of the hotel he returned to his room, and
+rang up Monsieur Lefevre.
+
+"I want the assistance of one of your men, Monsieur," he said.
+
+"Ah!" laughed the Prefect. "You are--what you Americans call--up a tree,
+is it not?"
+
+"Not at all. You have said that there existed between us a competition,
+to recover Mr. Stapleton's child. I think I am going to win. But since I
+am not in a position to make the necessary arrests, myself, I am going
+to share the glory with you, my dear friend, by allowing one of your men
+to do so for me."
+
+"So you are confident?"
+
+"Reasonably so. Can you spare Vernet for the day? He is a good man."
+
+"One of my best. You shall have him. And if you succeed, I shall still
+regard myself the loser, and will buy the champagne, and the dinner at
+the Café Royale, as I agreed."
+
+"And I shall be most happy to do the same should I fail. Oblige me by
+requesting Vernet to come to my rooms at the hotel at once. Good by."
+
+Duvall hung up the receiver, and sat down with the drawings he had made
+before him. He awaited the coming of Vernet with impatience.
+
+The latter appeared in some twenty minutes.
+
+"What can I do for you, Monsieur Duvall?" he asked.
+
+"Good morning, Vernet. Sit down, and have a cigar. I have a little
+matter I wish to talk over with you."
+
+"Concerning the missing child of Monsieur Stapleton, I understand,"
+remarked Vernet, as he lit a cigar and drew his chair up to the table.
+He glanced at the drawings before him. "What are these, may I ask?"
+
+Duvall took up his pencil. "This, Vernet, is a map of a small part of
+Paris. Here, as you see, is the Avenue Kleber, terminating at the
+Champs Élysées just in front of the Arc de Triomphe."
+
+"I see. It is quite plain."
+
+"Here--this black square--is Mr. Stapleton's house. From there to the
+arch is a matter of some six hundred yards."
+
+"About that, I should say. What of it?"
+
+"Wait. The black-bearded fellow--the kidnapper--who visited Mr.
+Stapleton last night, and escaped by the ruse of being arrested by one
+of his confederates, will arrive at Mr. Stapleton's house at eight
+o'clock tonight."
+
+"Mon Dieu! If that is so, we have him!"
+
+"Not so fast. We shall not interfere with him--then."
+
+"But, Monsieur, would you let this fellow escape? It is my duty to
+arrest him, as soon as he puts in an appearance."
+
+"You are mistaken, Vernet. Your duty is to do as I instruct you.
+Monsieur Lefevre has placed you under my orders for the day."
+
+Vernet laughed. "That is so," he said. "What do you wish me to do?"
+
+"The man will come to Mr. Stapleton's house at eight o'clock, and will
+be given a large sum of money. He has agreed, if he is not interfered
+with, to have the address where the boy may be found telephoned to Mr.
+Stapleton within half an hour."
+
+"Ah! Then we shall follow, and get him after he has telephoned."
+
+Duvall laughed. "We are dealing with a far shrewder man than that,
+Vernet. This fellow will do no telephoning."
+
+"Then how will he let Monsieur Stapleton know?"
+
+"That is just what I am trying to find out. Put yourself in his place.
+He is known--he dare not remain in Paris--he gets five hundred thousand
+francs to give up the child. Is it not natural to suppose that he will
+leave the city at once?"
+
+"Yes. That is what I should do, in his place."
+
+"Of course. Now I understand that the fellow will walk from Mr.
+Stapleton's house to the Arc de Triomphe, a distance of six hundred
+yards. He can do that easily in ten minutes."
+
+"Yes."
+
+"Once at the arch, he will stand awaiting a fast automobile, which will
+come along the Champs Élysées. This automobile will stop for an instant
+and pick him up, then proceed at high speed along the Avenue du Bois de
+Boulogne."
+
+"Why do you think that?"
+
+"Because it will afford him the quickest and safest road out of Paris.
+From the arch to the Porte Dauphine is less than a mile. He can make it
+in five minutes. In fifteen minutes altogether then, he is outside the
+walls. In another fifteen minutes, he is beyond pursuit, in the
+country."
+
+"But you forget, Monsieur Duvall, that he has not yet advised his
+confederates that all is well, and that the address of the place where
+the boy is hidden is to be telephoned to Mr. Stapleton."
+
+"No, Vernet, I haven't forgotten that. In fact, I am coming to it now.
+Suppose you were in this fellow's place--how would you do it?"
+
+Vernet scratched his head thoughtfully. "He might fire a pistol from the
+car."
+
+"Too dangerous. The noise of the explosion would attract attention. He
+must work silently."
+
+"A wave of the hand, perhaps, to someone along the street."
+
+"Also dangerous. This fellow realizes that every possible step will be
+taken to capture not only himself, but his confederates. He anticipates,
+no doubt, that the road will be carefully watched. Why take chances,
+and run the risk of his confederates, at least, being arrested, when
+there are simpler, easier ways?"
+
+"Such as what?"
+
+"Do you not remember the signal, used on the Versailles road, the blue
+light?"
+
+"Ah! Exactly. He will signal to some one in a house along the way."
+
+"That would be easier and safer; but you will remember that there are no
+houses along the way--none, at least, in which a man of this sort could
+have a confederate hidden. But I should not say none. There is one,
+perhaps."
+
+"Indeed, Monsieur. And what house is that?"
+
+"Mr. Stapleton's. Look!" He drew toward him the sheet of paper. "Here,"
+he placed the point of his pencil upon the black square which indicated
+the location of the banker's residence, "is the house. The north window
+of a room on the top floor commands a view of the Avenue du Bois de
+Boulogne, from a point some 500 feet west of the Arc de Triomphe, to
+where it intersects the Avenue Malakoff. Beyond there, the view is
+interrupted. In fact, the trees along the Avenue du Bois de Boulogne are
+to some extent an obstruction; but at the crossing with the Avenue
+Malakoff there is a wide and uninterrupted view."
+
+"But a confederate in Monsieur Stapleton's own house?"
+
+"Yes. The chauffeur, François."
+
+"You astonish me, Monsieur. We have suspected the fellow, it is true.
+The very room of which you speak has been searched. We found nothing.
+How do you know that what you say is true?"
+
+"Never mind how I know it--now. The point is this--François, I fully
+believe, will be in that room, tonight, at eight o'clock, watching
+carefully the automobiles which pass the intersection of the Avenue
+Malakoff--"
+
+"Not necessarily, Monsieur. We can easily prevent it, by placing him
+under arrest."
+
+"That is exactly what we must _not_ do. Don't you see, it is absolutely
+necessary, for the recovery of Mr. Stapleton's child, that the signals
+go through uninterrupted?"
+
+"Of course, I had forgotten that. And these signals?"
+
+"Naturally I cannot tell--yet. I think, however, that the automobile for
+which François will be looking will show a brilliant blue light, while
+crossing the Avenue Malakoff. That is, of course, if our friend the
+kidnapper gets safely away, without being pursued."
+
+"And otherwise?"
+
+"I think the light would be red. He can make either, very simply, by
+means of a powerful electric searchlight--one of these pocket affairs,
+you know, fitted with colored glasses."
+
+"You interest me wonderfully, Monsieur Duvall. What next?"
+
+"It is, of course, most important that the signal given shall be the
+correct one. There must be no interference whatever with this fellow's
+escape--_up to that point_."
+
+"Ah--I begin to see. And what after that?"
+
+"First, let us continue with François. He will, I think, return a blue
+signal to the man in the automobile, to show that he has seen, and
+understood. He has the means to do so all ready, in his room."
+
+"And then?"
+
+"He will make, I think, a similar signal from his south window to some
+one who is on watch, in the direction of Passy. This second person, who
+no doubt has the child in his care, will then go to a telephone,
+transmit the address of the house where the child is hidden, to
+Mr. Stapleton, and quietly depart, to join his confederate
+in--say--Brussels. He will run not the slightest risk of capture. If, on
+the other hand, that message fails to go through, the address will _not_
+be telephoned, and the child will probably be killed."
+
+Vernet frowned grimly. "It is a remarkable plan, Monsieur. These fellows
+are no bunglers. I think, however, that we shall be able to stop them."
+
+"How?"
+
+"I will station myself at the Porte Dauphine with a fast automobile, a
+racer. When these fellows pass, I will follow them, and overtake them."
+
+"An excellent idea, Vernet; but how, may I ask, will you know the car,
+when it passes you? There are hundreds of cars on the Avenue du Bois de
+Boulogne, at eight o'clock in the evening."
+
+Vernet laughed. "I confess, Monsieur, you have me there."
+
+"Of course you might station a man at the intersection of the Avenue
+Malakoff and the Avenue du Bois de Boulogne; but I do not think he
+would be able to see the signal. By placing on the end of the
+searchlight a paper tube, the light would be invisible except in the
+direction in which it is pointed--and that, you will remember, is
+diagonally upward. A man on the sidewalk would not see it at all."
+
+"Then, Monsieur, I fail to see that there is anything we can do."
+
+"There is one thing, Vernet. You forget the answering signal, from the
+window."
+
+The Frenchman looked at his companion with undisguised admiration.
+"Sacré!" he exclaimed. "You have a mind, Monsieur Duvall, in a
+thousand."
+
+"Thanks," answered Duvall, dryly. "Now, my idea is, to have you select
+some point near the intersection of the two avenues, from which the
+window in the rear of Mr. Stapleton's house can be clearly seen. Station
+yourself there, tonight, with the fastest automobile you can secure. Let
+one man watch the window, another the vehicles passing in the Avenue du
+Bois de Boulogne. The moment you see the blue light, start after your
+man. He should be just across the intersection, on his way down the
+Avenue du Bois de Boulogne."
+
+Vernet rubbed his hands together with satisfaction. "We shall get
+him--never fear."
+
+"Of course," said Duvall, slowly, "all this is pure assumption on my
+part, based upon what I have discovered in the chauffeur's room. It may
+not turn out as I say, but the chances are fifty to one that it will."
+
+"And you, Monsieur? Where will you be?"
+
+"I shall be in the room, with François. I do not propose that _he_ shall
+escape. And further--I do not know that I am correct, in my assumption
+regarding his signals to Passy. He may go out, and send the telephone
+message himself. In that case, I shall follow. Or he may, through some
+unforeseen accident, get the wrong signal, in which case I propose to
+overpower him, and give the right one. Suppose we go, now, and take a
+look at the intersection of the Avenue Malakoff and the Avenue du Bois
+de Boulogne, and see what arrangements can best be made. Also, if Mr.
+Stapleton is out in his car, we may be able to take a few observations
+from his chauffeur's window." He took up his hat, lighted a cigar, and
+led the way to the door.
+
+They drove to the Arc de Triomphe in a cab, and, after dismissing it,
+walked slowly down the Avenue du Bois de Boulogne. At the intersection
+with the Avenue Malakoff they stopped and gazed about carefully,
+although in such a way as not to attract attention. A brief inspection
+served to confirm all that Duvall had said. It took them some little
+time to locate the window in the rear of Mr. Stapleton's house; but
+after a time they managed to do so, and saw that it commanded an
+uninterrupted view of the point where they stood.
+
+Vernet was highly satisfied, as they parted. It was deemed unnecessary
+for him to visit the chauffeur's room, and thereby run the risk of their
+being seen entering the banker's house together. Vernet departed to make
+his arrangements for the evening, strictly cautioned by his companion
+not to let Monsieur Lefevre into his secret. "It is a bet," he told
+Vernet. "I hope we shall succeed in winning it."
+
+After his companion had departed, Duvall dropped in to see Mr.
+Stapleton. He learned that the banker was out, driving in the Bois with
+Mrs. Stapleton, who, overcome by anxiety and grief, had great need of
+the fresh air to retain her health. She was fast breaking down under the
+strain.
+
+Duvall went up to have another look at the chauffeur's room. He had been
+unable to get a thoroughly clear idea of the view from the window, the
+night before, owing to the darkness.
+
+He found everything as he had left it,--the searchlight on the dresser,
+the colored glass ornaments hanging from their gay ribbons. The north
+window overlooked with perfect clearness the intersection of the two
+avenues, as he and Vernet had seen them from below. The other window
+presented a more distant view. Nearby roofs and chimneys obstructed it
+in part; but between them could be seen the villas and buildings in
+Passy, smiling in the sunlight. The sight impressed Duvall the more
+strongly with the cleverness of the men he sought to arrest. Somewhere
+in all that maze of buildings, that wide vista of houses and trees and
+distant fields, Mr. Stapleton's child lay concealed, and it needed but a
+flash of light from this window to set him free. Passing his fingers
+idly along the window sill, Duvall suddenly observed two parallel
+scratches in the white paint, which had apparently been made with the
+point of a knife. He knelt down, and sighted between them. His line of
+vision swept clear of the nearby roofs and chimneys, toward Passy.
+
+The detective turned from the window, a smile of satisfaction on his
+face, and proceeded to make a careful examination of the chauffeur's
+closet. It was here that he intended to lie hidden. He felt certain
+that, in order the better to perceive and send his signals, as well as
+to escape detection from below, the chauffeur would allow his room to
+remain unlighted.
+
+This, Duvall reasoned, would render it easy for him to lie concealed
+until the signal which would insure the safe return of the lost child
+had been given, after which he would call upon François with precision
+and despatch. Should anything occur to prevent the chauffeur from giving
+the favorable signal, he proposed to give it himself.
+
+The closet was close to the north window, and its door opened in such a
+way that Duvall saw at once that in the darkened room he could readily
+open it sufficiently to see all that François did, without running any
+serious risk of detection.
+
+He left the house at a little after noon and stopped in at a well known
+restaurant on the Boulevard des Italiens for lunch. He felt very well
+satisfied with the course that events were taking. If only he could get
+through with this thing, and get back to Grace, and the farm, he would
+be supremely happy. He became so absorbed in his thoughts that he failed
+to notice a gentleman who slipped quietly into the chair opposite him,
+until the latter leaned over and touched his arm.
+
+He looked up suddenly. It was Monsieur Lefevre!
+
+
+
+
+CHAPTER XV
+
+
+The few seconds that elapsed while Grace Duvall stood in the deserted
+studio in Passy, waiting for the arrival of the person who was ascending
+the stairs, seemed like eternities, so crowded were they with terror.
+
+What should she do--what, indeed, could she do? A dozen plans raced
+madly through her brain, confusing her, baffling her with their
+futility.
+
+That the missing boy was within the sound of her voice, she knew; for
+even as she stood trembling at the ominous footsteps on the creaking
+stairs, she could hear the low troubled childish moaning, coming
+apparently from the very air in front of her, yet affording not the
+slightest clue as to the boy's whereabouts.
+
+She glanced about the room in desperation. Nearer and nearer came the
+creaking footfalls on the stairs. She dared not leave the room now, and
+thereby meet the approaching man face to face on the landing; yet to
+remain where she was would result only in her being obliged to make some
+lame and halting excuse for her presence, and go, as soon as the man
+entered the room.
+
+Even this she could not count upon. The fellow, no doubt a desperate and
+unscrupulous ruffian, might attack her, might detain her a prisoner
+until the child had been safely removed to another place, beyond all
+hope of discovery. All the work of the past twelve hours would come to
+nothing. And even should he let her go, in safety, he could not fail to
+suspect the reasons for her presence and warn his companions.
+
+Clearly the only thing to do was to remain in the room, in hiding. There
+was but one place in which she could hope to escape instant
+detection--the closet. Yet even this promised but temporary safety; the
+man would be almost certain to open it, for some reason or other, and
+discover her presence.
+
+It was her only chance, however, and she took it. Even as the footsteps
+of the approaching man sounded upon the landing outside, Grace flew
+across the room and into the closet, closing the door softly behind her.
+In her haste, one arm of a velveteen coat which hung upon a hook,
+became jammed in the door, with the result that it would not entirely
+close. She realized that it was too late to remedy the trouble now, and
+crouched back trembling with excitement.
+
+The jamming of the door had caused it to remain slightly open, with a
+space half an inch broad between it and the casing. Through this, Grace
+could see a part of the room before her. She watched the door to the
+hallway intently, as it was thrown open.
+
+The man she had seen in the pastry shop came in, several packages in his
+hands. These he placed upon a table, and at once began to prepare
+breakfast. A small alcohol lamp served for coffee, and butter, rolls,
+and fruit he produced from the paper bags before him. There was also a
+bottle of milk. Grace wondered if this was intended for the child.
+
+The man went about his preparations silently. Grace occasionally
+obtained a good view of his face. He was apparently about thirty years
+of age, dark and swarthy. There was something familiar about his manner,
+his general appearance; although what it was, she could not tell. She
+was certain, however, that she had seen him before.
+
+Once or twice he made a move, as though to approach the closet; but
+each time it was something else that claimed his attention. Once it was
+to get a package of cigarettes that lay upon one of the modeling stands.
+Grace wondered what she would have done, had he kept on toward her, and
+opened the closet door.
+
+She fell to thinking, in momentary snatches, about home, and Richard.
+How curious it seemed for them both to be here in Paris, separated for
+all these days, yet so near each other! She wondered if Richard had
+written to her, and what he would think, not to have heard from her.
+Then she remembered that after all he had been in Paris but a few
+days--there was scarcely time for a letter to have reached him. She
+thought of Uncle Abe, pottering about among the flower beds, of Aunt
+Lucy grumbling good naturedly over her wash tubs, of Rose, singing her
+queer camp meeting songs in the spring twilight, of Don, and the other
+dogs, the chickens, and her beloved flowers, and wondered how all of
+them were getting along with Richard and herself both away.
+
+Her reveries were interrupted by a sudden sound which made her start
+forward, tense with excitement. The man in the studio had gone for a
+moment beyond the line of her vision, into a corner of the room to her
+left. She could not see what he was doing there, and it was while
+waiting for him to reappear that she had fallen into her day dream.
+
+The sound which startled her was the voice of a child, not crying, this
+time, but speaking clearly and distinctly. "I want to go home!" it said,
+in a high nervous voice. "I want to see my mamma!"
+
+The man answered roughly, impatiently. "You can't go now. Be quiet and
+come and eat your breakfast."
+
+He appeared suddenly in the line of view commanded by the crack in the
+door, and Grace saw that he held a small boy by one hand, and was
+leading him to the table. Here he placed him in a chair and set before
+him a glass of milk and a roll. "Hurry up now!" the man growled. "Eat
+your breakfast. I've got to go out."
+
+The man's words set Grace's heart to beating with renewed quickness. If
+the man was going out, she would be able to escape, and take the boy
+with her.
+
+She did not doubt that he was Mr. Stapleton's child. The girl's dress
+which he had worn on the former occasion had been removed, and in place
+of it he wore a suit of dark blue, somewhat dirty and worn. His face
+still appeared to be very dark, and his hair, which had formerly been
+long and curly, was cropped close to his head. He appeared to be well,
+but very nervous. Grace watched him eagerly as he devoured the roll and
+milk.
+
+When he had finished, the man took him by the hand and again led him to
+the corner of the room beyond Grace's sight. She strained her face
+against the opening in the door, striving in vain to see what he was
+doing; but it was useless.
+
+She heard the boy begin to object, begging the man in a querulous voice
+to let him go out and play. His captor, however, silenced him with a
+sharp word, accompanied by a blow. "Get in there, and keep quiet!" Grace
+heard him say, and after that all was silent. A moment later the man
+reappeared, put on his hat, and, going out, locked the door carefully
+behind him. Grace wondered if the maid had told him of her call, and
+thereby roused his suspicions.
+
+She waited until she heard the front door close, and then, emerging
+quickly from the closet, went toward the side of the room to which the
+man had gone with the child.
+
+At first sight, there appeared to be no place where the latter could
+have been hidden. The two walls were of gray-tinted plaster, cracked and
+stained with age. There was a rickety chair and a battered plaster
+figure of a centaur, against which leaned an easel and a mass of
+sketches, covered with cobwebs and dust.
+
+With extreme care, she examined the walls and floor. It seemed most
+likely that some trapdoor existed, affording an entrance to a secret
+closet in which the boy had been placed. A few moments' effort showed no
+traces whatever of such a hiding place. The floor was of planks, covered
+with dust, and the cracks between the boards were filled with dirt and
+showed nowhere evidences of having been recently moved. The walls she
+sounded gently with the handle of a modeling tool which she snatched up
+from the table; but they gave forth a uniformly solid sound.
+
+She stood, surveying the place in perplexity. Then a sudden thought
+occurred to her. The ceiling! It swept low down, at the corner of the
+room, and above it she knew there must be an attic. She went over and
+began to examine the dusty plaster surface with minute care.
+
+A sound of footsteps upon the stairs sent her scurrying back into the
+closet. She wondered why the man had returned so soon. Greatly to her
+surprise, she saw, as soon as the door opened, that the newcomer was not
+the one who had left her a short time before, but an older man, more
+heavily built. As he turned and glanced toward the side of the room
+where she was hidden, she saw that he wore a heavy black beard. It was
+the kidnapper himself--the man whom she had seen at Mr. Stapleton's
+house the night before!
+
+He appeared to be annoyed, at not finding anyone in the studio, and
+after a moment sat down and lighting a cigar, began to read a newspaper
+which he drew from his pocket.
+
+Grace watched him intently, hardly daring to breathe for fear he might
+hear her. An hour passed, and the air in the closet became close and
+hot. She felt so nervous that she could have screamed, when the door of
+the room suddenly opened and Durand appeared.
+
+The two greeted each other with a nod. "Where have you been?" the older
+man demanded, somewhat angrily.
+
+"I had to get a new battery." He took a short black cylinder from his
+pocket and laid it on the table.
+
+"Is the boy here?"
+
+"Yes."
+
+"Good! Now listen to your instructions." He lowered his voice, glancing
+swiftly toward the closed door of the room. "At eight o'clock I shall go
+to the banker's house and get the money. At eight fifteen, or a little
+before, François will get his signal and repeat to you. If he flashes
+the blue light, you will release the boy, leave the room, lock the door,
+and go at once to the Place du Trocadero. From the little tobacco shop
+you will telephone the address of this place--No. 42, isn't it?--to
+Monsieur Stapleton. That will be about half past eight. Do not telephone
+before that. Then wait for me in front of the shop. Do you understand?"
+
+"Perfectly. And if I get the red signal?"
+
+"In that event, do not release the boy, but lock the door and come to
+the tobacco shop, as before. I will communicate with you there. Old
+Martelle is perfectly safe. But I do not think there will be any
+trouble. You will get the blue light."
+
+"You seem sure."
+
+"I am. This man Stapleton is not going to take any more chances. Once I
+am in the automobile, I am safe."
+
+"They could arrest you while you are walking to the Arc de Triomphe,
+after leaving the house."
+
+"That is true; but what would they gain. They would not get the boy,
+would they? And they have no evidence to show that I stole him. Further,
+François reports this morning that he overheard Stapleton and his wife
+talking. There is to be no interference--at least not until I get away
+in the machine. They will follow me, of course. I fully expect it. But
+you know the steps I have taken to take care of _that_ game." He laughed
+grimly. "No--no--the thing is absolutely safe. We will get away without
+the least trouble."
+
+"Nevertheless, if anything goes wrong, and I do not get the red signal,
+what shall we do then?"
+
+"We'll talk that over, when the time comes. You meet me at Martelle's."
+
+"But suppose you can't be there? They might get you, you know."
+
+The man with the beard frowned darkly, and an evil expression came over
+his face. "If you get the red signal, and I do not meet you at
+Martelle's at half past eight, come back here, get the boy, and take him
+to Lavillac. And before you do so, cut off his left hand, and send it to
+Stapleton with a letter telling him that if I am not set free at once,
+you will send his head. That will bring them to terms."
+
+Grace shuddered as she heard the man's words.
+
+His companion nodded. "I understand," he said. "But I hope it won't be
+necessary."
+
+"It won't. They can't get me. I've planned too carefully. That American
+detective, Duvall, is a joke. He was out on the Boulevard du Bois de
+Boulogne this morning with one of the Prefect's men. They are figuring
+to have an automobile at the Avenue Malakoff and follow me." He laughed
+loudly. "Much good that will do them!"
+
+"How about François?"
+
+"Oh--in a week or two, after we are safely away, François will sprain
+his wrist, and be forced to give up his position as Monsieur Stapleton's
+chauffeur. He will join us in New York."
+
+The younger man puffed meditatively at his cigarette. "What's become of
+that woman Lefevre had snooping around? Seen anything of her, since
+last night?"
+
+"No. She hasn't been about. Not much danger of _her_ finding out
+anything."
+
+The other rubbed his chin, in deep thought. "She nearly got you, last
+night," he presently remarked.
+
+"Oh, no. Not a chance. I knew she was in the house, and I figured she
+would telephone to headquarters as soon as she learned who I was. All I
+had to do was to signal you, through the window, and the thing was done.
+Of course I didn't expect the Prefect's man to get there quite as soon
+as he did; but you handled him all right." As he spoke, the man rose,
+went to a small mirror that hung on the wall, and carefully removed the
+black beard which was so distinguishing a feature of his appearance.
+
+"Pretty hot, this thing," he announced, as he threw it on the table.
+"Got anything to drink about? I'm thirsty."
+
+Grace saw, as he turned toward her, that he bore a striking resemblance
+to the masked man who had given her the first message to Mr. Stapleton,
+in the room of the house on the road to Versailles. She trembled as she
+heard him ask for the drink. Suppose the bottle should be in the
+closet? She shrunk back in terror as the younger man rose and started
+toward her.
+
+Her alarm was needless, however. The fellow drew open one of the drawers
+of a small dresser that stood on the opposite side of the room, and took
+out a light green bottle. "Absinthe?" he inquired.
+
+"All right. One won't do any harm. Don't take any more, though." He
+began to pour out the drink into a glass which stood upon the table.
+"When you get the signal from François," he went on, "you are to answer
+it, as usual, so he'll know you've seen him. He doesn't want to stay in
+his room very long--for fear he might be missed."
+
+"They suspect him, of course."
+
+"Yes. He's being watched right along; when he's out of the house, that
+is. They've searched his room, and all that; but they haven't found
+anything." He chuckled, and began to sip his drink. "Nothing to find."
+
+The other man sat down at the table, and the two began talking over
+their plans of escape. Grace could not hear all they said; but, as
+nearly as she could gather, they intended, as soon as the younger man
+had joined the other, to run for Brussels in the automobile. Near the
+frontier they would leave the machine, change their disguises, and cross
+the frontier on foot. Once in Belgium, they seemed to think they would
+be quite safe.
+
+It was along toward noon when the older man readjusted his disguise and
+left the house. "I'm going to get something to eat," he announced. "I
+won't be back. You'd better not leave the place again. I'll send you in
+something, if you like." He glanced at the rolls and milk on the table.
+
+"It won't be necessary. I've got all I need. Guess I'll take a nap this
+afternoon. Well, good luck," he concluded, as the other started toward
+the door. "See you later."
+
+"All right." The black-bearded man passed noiselessly into the hall.
+"Don't sleep too long. Eight o'clock, remember." In a moment he was
+gone.
+
+Grace watched the other as he finished drinking his absinthe and lit a
+cigarette. Presently he went over to the cot and, throwing himself upon
+it, was soon snoring loudly.
+
+The long hot afternoon wore itself on. Grace leaned back against the
+wall of the closet, weak from the nervous tension of the situation. The
+place was hot and close. She felt faint from lack of air, from hunger.
+At times she dozed off, then recovered herself with a start, and stood
+trembling, fearful lest she had made some noise which might attract the
+attention of the sleeping man.
+
+After a time, the low complaining of the child began again, at first
+faint and seemingly far off, then growing in volume, until the tearful
+cries of "Let me out--let me out!" seemed to come from a point scarcely
+beyond the reach of her hand.
+
+The child's complaints at last awoke the sleeping man. With a muttered
+curse he rose, crossed the room, and disappeared from sight. Grace heard
+a low scraping sound, as of a panel being drawn back, and presently the
+man again appeared with the child, and again supplied him with bread and
+milk.
+
+After he had eaten, the man gave him a magazine with bright-colored
+pictures in it, to amuse him, and lay on the bed, smoking. The boy sat
+on the floor, looking at the book.
+
+Once or twice he tried to speak, but the man sharply bade him be quiet.
+About sundown, a step was heard on the stairs, and once again the boy
+was hastily placed in his hiding place, with threats of punishment if he
+cried.
+
+The new arrival was only a model, in search of work. The man spoke to
+her gruffly, and informed her that he had all the models he needed.
+After she left, he did not again release the child, but sat, reading,
+for a long time.
+
+At last he rose, took up the short black cylinder, which Grace saw was
+an electric searchlight, from the table, and went over and sat in the
+sill of the large double window which faced to the north. The window was
+open, and the room in darkness.
+
+Grace pushed the door of her closet open slightly, so as to get a better
+view. The window was directly opposite the closet, at the other end of
+the room. She could see the silent figure of the watcher, silhouetted
+blackly against the night sky without. Off to the north were many
+lights--the lights of the houses toward the Champs Élysées, and the Arc
+de Triomphe.
+
+For many minutes she watched, over the man's shoulder, waiting for the
+signal which would set both herself and Mr. Stapleton's boy free from
+their long confinement.
+
+Presently she heard the man utter a quick oath, and saw him peer out of
+the window, his figure tense and rigid, a pair of field glasses held to
+his eyes. In another moment he had dropped the glasses, picked up his
+electric searchlight, and flashed a signal into the darkness.
+
+It took him but a moment. In another he had rushed to the door, and
+Grace heard him turn the key in the lock and clatter down the stairs.
+
+She crept swiftly to the window and looked out. At first she could see
+nothing, but a confused maze of lights. In a moment she had seized the
+field glasses and was nervously sweeping the horizon. Suddenly she held
+them still for a moment, then drew back with a cry of dismay. Far off
+toward the Avenue Kleber there gleamed a light, high in the upper room
+of a house. It shone for a few moments, steady, baleful, full of unknown
+terror, then winked suddenly out and was gone. She dropped the field
+glasses upon the floor and staggered back against the table. _The light
+was red!_ She was locked in. The two men would undoubtedly be back in
+fifteen or twenty minutes. And then--she shuddered as she thought of
+what they intended to do to the kidnapped child. To herself she gave
+scarcely a thought. Then Richard's face came before her eyes, and she
+fell upon the window seat, sobbing bitterly.
+
+
+
+
+CHAPTER XVI
+
+
+When Monsieur Lefevre touched Richard Duvall on the shoulder, in the
+restaurant in the Boulevard des Italiens, he was filled with a very
+great feeling of anxiety, although he concealed it behind a mask of
+pleased surprise at the unexpected meeting.
+
+Since early the evening before he had had no word from Grace. He knew
+from Mr. Stapleton that she had left his house a short while after nine;
+but since then she had completely disappeared.
+
+The Prefect at first thought that she had been unable to keep her
+identity from her husband any longer, and had joined him. He later
+learned from Vernet that this was not the case. Now the old gentleman
+began to feel seriously alarmed at her continued absence.
+
+"How goes everything, my friend?" he asked, with an elaborate show of
+carelessness. "Have you found the kidnappers yet?"
+
+Duvall smiled. "Not yet. But I expect to have them, before the evening
+is over."
+
+"Indeed! I congratulate you. Have you seen anything of Mademoiselle
+Goncourt?"
+
+"No. Why?"
+
+"I thought perhaps you might have met her. You two are after the same
+game, you know."
+
+Duvall smiled grimly. "I don't believe she's following the same trail
+that I am," he said. "I expect to win that bet, Monsieur."
+
+The Prefect seemed a trifle uneasy. "The evening is not yet over,
+Monsieur," he replied. "But, in any event, I hope that Monsieur
+Stapleton's son will be returned to him without further delay, whoever
+brings about the result."
+
+"Come to his house tonight, Monsieur. I have arranged a little matter
+with Vernet which may surprise you. And then, too, we shall have to go
+and get the boy." He rose, and took up his hat. "We shall want you with
+us."
+
+"By all means. I shall be there, my friend. What hour would you
+suggest?"
+
+"Half past eight, at the latest."
+
+"Good! I shall be there at that time. Good day, _mon ami_."
+
+"Au revoir. Give my respects to Mademoiselle Goncourt." He left the
+restaurant and, going to his room at the hotel, proceeded to write a
+long letter to Grace. He reproached her for not having written to him.
+Here he had been in Paris four days, and had not heard a word from her!
+A letter, he felt, should have come by the very next steamer--several,
+in fact. He told her how greatly he missed her, how deeply he loved her,
+and how soon he hoped to return to her arms. And even as he wrote,
+Grace, half dead from fatigue, stood hidden in the closet at Passy, a
+mile away, watching with frightened eyes the kidnapper asleep on the
+pallet bed.
+
+Duvall had arranged to be at Mr. Stapleton's house a little before eight
+that night, and it still lacked twenty minutes of the hour when he
+ascended the steps of the banker's residence and was ushered into the
+library.
+
+Mr. Stapleton sat in grim silence, awaiting the coming of his visitor.
+He did not seem particularly glad to see Duvall. The latter's apparent
+failure to make any headway in the matter of recovering his missing boy
+had caused the banker to lose confidence in his abilities.
+
+"Good evening, Duvall," he remarked, indifferently.
+
+"Good evening, Mr. Stapleton. You are ready for your man, I see." He
+glanced at the package of banknotes which lay at the banker's elbow.
+
+"Quite. You have done nothing to interfere with his coming or going, I
+trust."
+
+"Nothing."
+
+Stapleton glanced at the clock. "He will be here very soon, now. May I
+ask you to wait in my study, upstairs? It would never do for you to be
+here. The man might be afraid to enter."
+
+"No--you are right. I must not be here. But I prefer not to wait in the
+study. I have another plan."
+
+"What is it?" inquired the banker, uneasily.
+
+"Where is François, your chauffeur?"
+
+"At his dinner, I believe. Why?"
+
+"Will you kindly find out for sure? I want to go to his room."
+
+Mr. Stapleton summoned a servant, who told him that the chauffeur was
+just finishing his dinner. "You will be very careful, Duvall," he said,
+anxiously. "I don't want anything done which will alarm these fellows."
+
+"Oh, François won't see me. I shall keep out of his sight. Perhaps I had
+better go up now." He nodded to the banker, and at once ascended the
+stairs which lead to the servants' quarters.
+
+At the door of the chauffeur's room he paused. It was closed. He pushed
+it gently open, and in a moment was in the room. The place was quite
+dark; but by means of a pocket light Duvall soon found the closet, and a
+moment later was safely ensconced within. He left the door ajar, and to
+his satisfaction found that he could see through the north window
+without difficulty. Here he waited, until the chauffeur should arrive.
+
+Mr. Stapleton, meanwhile, sat grimly in the library below, waiting for
+the coming of the kidnapper. Promptly at eight o'clock, his butler
+announced that the man had arrived.
+
+"Show him in at once," exclaimed the banker, as he rose and began to
+walk up and down the room.
+
+In a moment the man came into the library. His powerful figure, his
+black beard, his assured manner, rendered him an easily recognized
+figure.
+
+"I have come, Monsieur, as I said I would," he remarked, calmly. "I
+trust you have the money in readiness."
+
+Stapleton stepped over to the desk and picked up the package of
+banknotes. "Here it is," he growled. "I understand that you will, in
+return for this money, send me word at once as to where my son is to be
+found."
+
+"Within half an hour, Monsieur, at the latest; provided, of course, I am
+not interfered with in my escape."
+
+"There will be no interference, until I get back my boy. After that, I
+shall spend another hundred thousand dollars, if need be, to bring you
+to justice."
+
+"That, Monsieur, is quite within the terms of our agreement. The moment
+you receive the address, you are free from any obligation to me. May I
+see the money?" He extended his hand.
+
+Mr. Stapleton placed the banknotes in it. "Count them," he growled, "and
+assure yourself that you have received the amount you demand."
+
+The kidnapper sat down with the utmost coolness and began to count over
+the notes. They were all of large denomination, and the operation
+consumed but a few moments. As soon as he had finished, the man placed
+the bundle of notes carefully in an inside pocket and rose. "The amount
+is correct, Monsieur," he said. "Permit me to bid you a very good
+evening." Without further delay, he bowed, took up his hat, and left
+the room.
+
+At the door he glanced quickly at his watch, then strode off up the
+street at a rapid pace, toward the Arc de Triomphe.
+
+For some eight or ten minutes he walked, at the expiration of which time
+he arrived at the Place de l'Étoile, and at once crossed to the pavement
+surrounding the great triumphal arch.
+
+Up and down the twelve great avenues which radiate from the Place of the
+Star flashed innumerable automobiles, coming and going like huge jeweled
+fireflies.
+
+The kidnapper paused at a point on the very outer edge of the circular
+pavement which surrounds the arch, and waited, expectant, his eyes fixed
+upon the broad sweep of the Champs Élysées.
+
+For some moments he stood thus, rigid, motionless. Suddenly a big black
+racing car swept from the line of traffic and approached the curb. The
+man on the sidewalk raised his hand, and made a momentary gesture. The
+car quivered to the side of the street, pausing but the fraction of a
+second as the tall figure of the kidnapper stepped in. Another moment,
+and it had swept around the great arch and was flying down the Avenue du
+Bois de Boulogne.
+
+Close behind it came a second car, which, like the first, contained but
+a single occupant in addition to the chauffeur. With scarcely fifty feet
+between them, the two machines swept down the broad street toward the
+intersection with the Avenue Malakoff.
+
+In a few moments, both had reached it. But here their ways parted. The
+first car, turning in a quick and dangerous quadrant, swept into the
+Avenue Malakoff and sped southward like the wind. The second car
+continued on toward the Porte Dauphine. As it passed the intersection
+with the Avenue Malakoff, the chauffeur, unobserved by his passenger,
+directed a cylindrical black object toward the southern sky and held it
+there, motionless, until his car had disappeared in the shadow of the
+trees to the west.
+
+Just inside the Avenue Malakoff lay a third car, its powerful engine
+shaking it from end to end with its rapid pulsations. Two men sat in the
+tonneau. One of them was occupied in watching a distant window in the
+rear of a house on the Avenue Kleber with a pair of field glasses. The
+other kept his gaze fixed upon the road before him.
+
+Suddenly the man with the field glasses turned, and pointed toward the
+car which was just passing from sight along the Avenue du Bois de
+Boulogne. "Quick!" he muttered. "After him!"
+
+The automobile shot forward like a racehorse under the whip, and in a
+moment was flying down the avenue in hot pursuit.
+
+The foremost car was making high speed; but the one which pursued it was
+clearly the faster of the two. Slowly the space which separated them
+began to decrease. The man in the first car spoke quietly to his
+chauffeur, and the great car jumped forward with renewed speed.
+
+Vernet, in charge of the pursuing car, swore softly to himself as he saw
+his quarry pull away from him. He had confidence, however, in the speed
+of his own machine, and urged his driver to greater efforts.
+
+For several miles the two swept on, the rear car gaining slowly, in
+spite of the other's best efforts. They had passed the fortifications
+and were now in the Bois de Boulogne, and with clearer roads ahead the
+chase seemed likely to be a long one.
+
+Suddenly, to Vernet's astonishment, the forward car began to slow up. In
+a moment the Prefect's men ranged alongside, and covered the solitary
+passenger with their revolvers.
+
+"Surrender!" Vernet cried. "You are my prisoner."
+
+The man in the other car looked up, and calmly began to light a
+cigarette. "Are you a bandit, my friend?" he inquired, calmly.
+
+The detective was taken aback. The two cars had now come to a standstill
+at one side of the road. "Search him!" he said quickly to his companion.
+
+The second man climbed into the car. Its occupant made no protest. "What
+do you wish with me, gentlemen?" he asked, with a sarcastic smile. "My
+watch--my money?"
+
+"The searchlight, first of all," replied the detective, "with which you
+signaled."
+
+The man looked at him in astonishment. "What are you talking about,
+Monsieur?" he inquired. "Is this then a joke?"
+
+Vernet began to feel a trifle uneasy. This man certainly did not appear
+to resemble in any way the prisoner he had sought. He was a clean-shaven
+young man, elegantly dressed, and quite evidently a gentleman. "Do you
+deny," asked the detective, "that on passing the Avenue Malakoff a few
+moments ago you flashed a blue light toward the Avenue Kleber?"
+
+The young man laughed. "Of course I deny it," he said. "Why the devil
+should I be flashing blue lights at the Avenue Kleber? And who are you,
+to ask me any such nonsensical questions?"
+
+"I am an agent of the police, Monsieur. Who are you?"
+
+"I am Anton Lemaitre, stock broker, of the firm of Lemaitre and
+Bossard." He handed a card to the dumbfounded Vernet. "I am trying a new
+automobile, which I think of purchasing. My chauffeur proposed that we
+try it out in the Bois, where there is more opportunity to speed than in
+the city."
+
+"Why did you then run away?"
+
+"My dear sir, I saw you following me. I wish to own a fast car--the
+fastest car in Paris, if possible. I directed my driver to see what he
+could do. I do not believe, however, that I shall now buy the car, since
+yours is faster. What make is it, Monsieur, if I may ask?"
+
+Vernet smothered an oath. Clearly this man was telling the truth. He
+directed his companion to get in with Monsieur Lemaitre. "Drive to the
+Prefecture," he said, "and let the gentleman tell his story to Monsieur
+Lefevre." He himself ordered his chauffeur to proceed with all despatch
+to Mr. Stapleton's house. The affair had ended in a fiasco. He felt that
+he must see Duvall at once.
+
+In fifteen minutes he was at the house. Mr. Stapleton was waiting
+patiently in the library for the telephone call which would announce the
+hiding place of his boy. With him were Mrs. Stapleton and Monsieur
+Lefevre.
+
+The poor man and his wife were in a pitiable state, their eyes glued to
+the clock which stood on the mantel. It was marked twenty-six minutes
+past eight. "Only four minutes more!" gasped Mrs. Stapleton, through her
+tears. "My God! why don't they hurry?"
+
+Her husband endeavored to console her. "They may be a few moments late,
+my dear. Don't excite yourself. I am sure they will keep their word."
+
+Vernet went over to Monsieur Lefevre and explained the events of the
+evening in a few words. The Prefect smiled grimly. "So Monsieur Duvall
+has failed again!" he remarked, in a low voice. "Mon Dieu! If we do not
+soon hear from Mademoiselle Goncourt, I shall begin to feel nervous
+myself."
+
+Slowly the hands of the clock crept around. As the half hour was
+reached, and the telephone bell remained silent, Mrs. Stapleton uttered
+a groan of despair, and sank upon the couch, weeping pitifully. Mr.
+Stapleton, watch in hand, paced up and down the room. "They have been
+interfered with," he stormed, "or they would have communicated with me
+before now!" He turned to Monsieur Lefevre. "You have done nothing, I
+hope, to again prevent me from recovering my son?"
+
+"Nothing, Monsieur."
+
+Mr. Stapleton waited another five minutes. It now wanted twenty minutes
+to nine. The telephone bell remained persistently silent. The banker
+closed his watch with a snap and thrust it into his pocket. His face was
+pale with rage and suffering. Drops of perspiration collected on his
+forehead. "The scoundrels!" he cried. "They have broken their word, and
+robbed me of a hundred thousand dollars in the bargain. I will give
+another hundred thousand to the man who will capture them, dead or
+alive, and find my boy!"
+
+There was a profound silence, broken only by the quick sobbing of Mrs.
+Stapleton. Neither Lefevre nor Vernet ventured to speak.
+
+Suddenly there arose sounds of a commotion among the servants gathered
+in the hall without. In their devotion to their employer they had
+collected there to welcome the lost boy. There were exclamations, cries
+of astonishment--and dismay.
+
+The occupants of the room turned in surprise toward the door. As they
+did so, Richard Duvall appeared in the doorway. He staggered, and with
+difficulty supported himself by clutching the side of the door. His face
+was covered with blood, his clothes torn and disheveled.
+
+He swayed a moment, unsteadily in the door.
+
+"What is it--what is wrong?" cried Stapleton, starting toward him.
+
+"The child is at 42 Rue Nicolo, Passy," gasped the detective, then fell
+heavily upon the library floor.
+
+
+
+
+CHAPTER XVII
+
+
+Richard Duvall, waiting with nervous impatience in the closet in
+François' room, at last heard a soft and guarded step upon the stairs.
+He drew back, his muscles tense, and gazed fixedly at the door.
+
+Although the room was dark, the glow of the street lamps from without,
+the faint light of the evening sky, sufficed, now that his eyes had
+become accustomed to the darkness, to enable him not only to recognize
+the chauffeur as he entered the room, but to follow his movements with
+little or no difficulty.
+
+The man seemed hurried. He groped his way to the dresser at the opposite
+side of the room, and felt about for the searchlight which Duvall knew
+lay within easy reach.
+
+Having secured it, he directed it for a brief moment upon his watch,
+noted the time, then, going to the door, opened it, and began to listen
+intently.
+
+The detective at once surmised that he was listening for the departure
+of his confederate, the man with the black beard.
+
+Presently the chauffeur drew back, closing the door with a grunt of
+satisfaction, and once more approached the dresser. Duvall concluded
+that he had gone to get the colored glasses by which he would be able to
+make the required signals.
+
+In a moment he returned to the window, and Duvall saw him place the two
+glass cups upon the sill, and lean out expectantly.
+
+It seemed a long time before he stirred. The detective, looking over his
+shoulder, found that his line of vision was interrupted so that he could
+not see the lights which flashed past the entrance of the Avenue
+Malakoff. He was forced to content himself with keeping a close watch
+upon the chauffeur.
+
+Suddenly the man, by an almost instantaneous movement, clapped one of
+the little glass cups over the end of the tube which formed the
+searchlight, and directed it toward the street. Duvall could not tell
+whether the signal was blue, or red. He had every reason to believe,
+however, that it was the former.
+
+The chauffeur held the tube upon the window sill for a few seconds
+only, then withdrew it, and started to cross the room toward the south
+window. As he did so, he swept the light into the room, and for an
+instant it fell upon the crack in the closet door through which Duvall
+was peering. He was conscious of a blinding blue radiance, close to his
+eyes, and the sudden flash caused him to draw back with a quick and
+involuntary movement. He realized that the chauffeur had not seen him,
+and that, in a few moments more, the signal would be given which would
+bring untold happiness to both Mr. Stapleton and his wife.
+
+The momentary recoil, however, was fatal to his plans. Although he moved
+his head but a fraction of an inch, the suddenness of the movement was
+sufficient to cause a metal coat hanger, which hung, empty, from a hook,
+to click sharply against its neighbor.
+
+The chauffeur spun around with the quickness of a cat, and, grasping the
+knob of the closet door, threw it open. In his hand he still clutched
+the tube of the searchlight.
+
+Duvall at the same moment reached for the revolver which lay in a side
+pocket of his coat. He realized instantly that, now that his presence
+had been discovered, the chauffeur would of course not send the signal
+to his confederates in Passy which would result in the telephoning of
+the address to Mr. Stapleton, but would on the contrary flash a red
+signal, which the detective fully believed would result in the child's
+death.
+
+It was imperative that this should be prevented. Duvall had determined
+to be present in the chauffeur's room for two reasons,--first, to send
+the favorable signal to Passy himself, should things go wrong, and the
+chauffeur receive a red flash from the street; secondly, to arrest
+François in the act of receiving and sending the signals.
+
+He now realized that he must do both, and that, too, without a moment's
+delay.
+
+As the chauffeur threw open the door he flashed the blue light full upon
+the crouching figure of the detective.
+
+The latter, revolver in hand, commanded him sharply to throw up his
+hands.
+
+The chauffeur did so--thereby directing the light of the electric lamp
+toward the ceiling. The sudden change from the glare which an instant
+before had been in his eyes, to almost total darkness, left Duvall
+momentarily blind. His eyes could not instantaneously respond to the
+withdrawal of the light. The figure of the chauffeur appeared but a dark
+and formless shadow.
+
+The latter, however, not having faced the glare of the light, was able
+to see without difficulty. With lightning like quickness he spun around
+on one foot, until his back instead of his face was toward the
+detective. Then his right foot rose, in the famous and deadly blow of
+the _savate_.
+
+It has been said that this backward kick, so dear to the heart of the
+Parisian crook, is more to be feared than any possible onslaught in good
+old Anglo-Saxon style with the fists. Certainly in this instance it was
+too much for Richard Duvall. The unexpected blow, coming during the
+moment when the sudden darkness had left him blinded and confused, sent
+him crashing back into the depths of the closet, buried beneath a mass
+of clothing. His arms, entangled in falling coats and waistcoats, were
+helpless. The revolver flew from his hand, and lay useless on the floor.
+
+The chauffeur went about his business calmly. His first move was to
+direct the searchlight carefully into the interior of the closet,
+slipping the blue cup from the end of it as he did so and allowing it
+to fall unheeded to the floor. His second was to draw a long and
+peculiarly deadly looking knife.
+
+His quick eye saw at once that the revolver was no longer in the
+detective's grasp. His searchlight enabled him to discern it, lying on
+the floor to one side of the closet. Before Duvall could extricate
+himself from the articles of clothing in which he was entangled,
+François had stooped quickly, picked up the revolver, and slammed the
+door of the closet upon him. As he struggled to his feet, the detective
+heard the click of the key as it turned in the lock. He was a prisoner.
+
+Without losing a moment, the chauffeur tossed the revolver upon the
+table, took up the cup-shaped bit of red glass, fitted it to the tube of
+the searchlight, and, going to the south window, placed it upon the sill
+in such a way that its crimson glare was directed almost due south. It
+was evident that the position in which the light was placed was marked
+by the two tiny scratches cut in the woodwork of the window sill. In a
+moment he had turned back toward the closet door.
+
+Duvall, meanwhile, realized that only by instant and superhuman effort
+could he hope to remedy the frightful situation which his unlucky
+movement had precipitated.
+
+He braced his shoulders and back against the rear wall of the closet,
+put his two feet against the door, and with every atom of strength in
+his body strove to force it open.
+
+His movements had been quick. Just as the chauffeur turned back from the
+window toward the room, Duvall, his muscles knotted with effort, drove
+the full force of his body against the closet door.
+
+The lock, a cheap affair, was torn loose in a twinkling, and an instant
+later the two men had grappled in the center of the room.
+
+The detective's one desire was to get to the window, remove the red
+light which he knew was flashing its fateful message across the
+housetops, and substitute for it a blue light, which he hoped even now
+might shine forth in time to redeem the situation.
+
+This, however, the chauffeur was equally determined to prevent. He
+realized that he was caught, that his complicity in the affair was
+known, and that he must warn his comrades of his danger, so that, by
+refusing to give up the boy, they might effect his release. He was
+fighting for his liberty as desperately as Duvall was fighting for that
+of Mr. Stapleton's child.
+
+The two men were evenly matched. The chauffeur was perhaps the stronger,
+in shoulders and arms, due to his profession. The constant grip upon the
+steering wheel had given to his upper body muscles like steel.
+
+The detective, though somewhat less powerful in this direction, was
+stronger in the back and legs. He had been an athlete, at college, and
+his recent life upon the farm at home had toughened and hardened him
+from head to foot.
+
+He rushed at his opponent, threw his arms around the latter's waist, and
+strove to lift him and throw him to the floor.
+
+The chauffeur at the same time got his right arm about Duvall's throat,
+and with his left did his best to gouge out one of the latter's eyes.
+His was the style of fighting that considers not means, but results.
+
+For a moment they swayed heavily about the room, the detective burying
+his face in his opponent's side to protect his eyes, and at the same
+time striving with all his might to force him back toward the bed.
+
+François, however, fought well. He began to compress his adversary's
+throat in a choking grip of wrist and forearm which threatened to put an
+end to the struggle in short order. At the same time his left thumb
+continually sought the detective's eyes.
+
+Suddenly it reached one of them. Duvall felt a blinding sense of pain as
+the thumb nail sank into the soft and tender muscles about the eye. The
+shock was fatal to the plans of the chauffeur; for it raised up in his
+opponent a great and deadly rage, that for an instant gave him the
+strength of a madman. He raised his opponent from the floor as though
+the latter had been a child, broke the grip upon his throat by
+straightening his head, and with a mighty heave hurled him to the floor.
+
+The fellow struck upon his side, his temple crashing loudly against the
+wooden floor. Duvall stood over him for an instant, breathing heavily,
+convulsively, then turned and snatched the searchlight from the window
+sill and threw it upon the bed.
+
+There was a trunk against the wall of the room, near the window, and
+about it a broad leather strap. Duvall tore the strap from its place,
+and in a few moments had fastened it about the chauffeur's arms and
+body.
+
+A towel, knotted about his ankles, rendered him helpless. Then the
+detective began to search upon the floor for the bit of blue glass.
+
+In his heart there was no joy at the victory he had just won. He had
+captured one of the kidnappers, it was true; but on the other hand he
+had, by his own carelessness, prevented the safe return of the kidnapped
+boy to his parents.
+
+He pictured the father and mother, patiently waiting below for the
+telephone message which would never come, and wondered how he would dare
+to tell them the truth.
+
+At last his nervous fingers closed upon the little glass cup, where it
+had rolled under the edge of the dresser when François had thrown it
+down. Trembling with haste, he fixed it to the searchlight which he took
+from the bed, and, with a hopeless feeling, approached the window, and
+began to wave the light frantically in the direction of Passy.
+
+For several moments there was no response. As a matter of fact, he
+scarcely expected any. Then all of a sudden he saw a faint red gleam,
+like a star, flash from the distant night, and then go out.
+
+He stood, helpless, waiting for it to reappear, hardly daring to hope
+that it would do so. Suddenly it shone again, this time for a longer
+period, and then disappeared. He wondered what it meant, and was
+scarcely surprised when the light again flashed, this time making five
+quick flashes, which he instantly recognized as Morse code for the
+letter "P." There was a brief interval, then once more the signals began
+to flash. This time he read them without difficulty. There were four
+letters, spelling the word "Help."
+
+For an instant he leveled the tube of the searchlight toward the point
+from which the flashes came, guiding it by the scratches on the sill,
+and began pressing the button which turned the light on and off. "Where
+are you?" he spelled out, then waited fearfully for the reply. He dared
+send no other message. The person at the other end, the one who sent
+this ominous word, "help," must be one of the kidnappers; yet why should
+he signal for assistance? He could make nothing of the matter, but he
+reasoned that anyone calling for help would be sure to give their
+location, otherwise how could they expect to receive it.
+
+For a moment the red flashes began again, and this time he began to get
+the numbers. There were four quick flashes and a long dash, then others
+in rapid succession: "4-2-R-u-e-N-i-c-o-l-o, P-a-s-s-y," the message
+read. "C-o-m-e q-u-i-c-k."
+
+Duvall's head reeled, as he spelled out the words. He had not realized
+until now that he was wounded. The blood, pouring down his face from the
+great gash in his cheek, spattered thickly upon the window sill. He
+turned from the window, then realized that he must send some answer, to
+let this mysterious person at the other end of the line know that his
+message had been safely received.
+
+"Will come at once. Who are you?" he spelled out, laboriously, his head
+spinning, his fingers trembling from weakness as he tried to stop the
+flow of blood from his wound.
+
+"G-R-A-C-E D-U-V-A-L-L" came back the flashes, quick, clear cut,
+unmistakable.
+
+Duvall dropped the searchlight to the floor with a harsh laugh. His
+brain was reeling--the whole thing became a foolish, senseless
+nightmare. He wondered if he was delirious, and had dreamed it all.
+Again he flashed a signal into the darkness. "Who are you?" he spelled
+out again. He did not believe that he had read the former answer aright.
+Evidently his imagination was playing him tricks--Grace had been on his
+mind so constantly, throughout the day. He wiped the blood from his eyes
+and stared eagerly out into the darkness. There was no response.
+
+Then he remembered the words of the message, "Come quick." There was no
+time for idle speculations as to the identity of the person who had sent
+him the message.
+
+He rushed to the stairs, and with tottering footsteps descended to the
+library below. François, the chauffeur, still lay, bound and
+unconscious, upon the floor.
+
+
+
+
+CHAPTER XVIII
+
+
+For a few moments after being left alone in the studio at Passy, Grace
+almost lost her courage. She knew that the man who had remained on guard
+in the room had received the danger signal--the red light--which told
+him that the plans of his confederates had miscarried. She remembered
+the instructions which the black-bearded man had given him. "If I do not
+meet you at Martelle's, take the boy to Lavillac. And before you do so,
+cut off his left hand and send it to Mr. Stapleton."
+
+The very thought of the thing made her sick. She rushed to the door, and
+tore frantically at the knob; but it resisted all her efforts. She
+glanced at the windows, knowing that to escape by means of them from her
+position on the top floor of the house was impossible. And then--should
+she escape, she would be obliged to leave the child, and this she by no
+means wanted to do.
+
+Suddenly she heard again the faint moaning. The sound almost drove her
+frantic. She rushed to the window and looked out, praying for guidance,
+for some ray of hope in the frightful situation in which she found
+herself.
+
+Already several minutes had passed since the departure of the man. It
+would not be long, she felt, before he returned, and, for all she knew,
+the black-bearded man with him. Would they attack her, if they found her
+there? She could hide again, of course; but that would not accomplish
+anything, except perhaps, to save herself. And she had set out to rescue
+the child.
+
+In a whirl of indecision, she glanced out of the window, toward the
+point in the north where she had seen the red light. She wondered where
+it was, from what place it had been sent. Then suddenly, as she swept
+the horizon with eager eyes, she saw, where a few moments before the red
+light had flashed, a gleam of blue. Unlike the red signal, however,
+which had been steady, as though fixed in place, this one moved about
+restlessly, now pointing full at her, now almost disappearing to the
+right or left.
+
+She seized the field glasses and gazed at the light in wonder. Did this
+mean that the kidnappers had been successful, after all, and that the
+former signal had been a mistake, or did it indicate that the person
+giving the first signal had been overpowered, and that the light was in
+the hands of friends?
+
+She had no means of knowing; but here was someone who was trying to send
+her word that all was well. She determined to reply.
+
+Her one thought was to get to Mr. Stapleton her present address. She
+knew that the man who had been intrusted with the task of telephoning it
+to the banker, would not now do so. She would try to send the address
+herself.
+
+Then came to her a great feeling of joy, that she was familiar with the
+Morse code. Richard had taught it to her, during their trip from Paris
+to New York the year before. She remembered how she had been interested
+in the wireless, and Richard had offered to teach her the alphabet.
+
+She picked up the searchlight and examined it. It was an ordinary pocket
+lamp, with a dry battery, such as are sold at stores dealing in
+electrical goods, and she saw, from its size, that it was an unusually
+powerful one.
+
+Midway along one side was a tiny button, by pressing which the circuit
+was completed, and the light made to flash. By pressing this button
+momentarily, she could get a quick flash, comparable to a dot. By
+holding it down longer, she could produce a dash.
+
+She did not stop to remove the red glass which was fixed over the front
+of the light; in fact, she concluded that it would be better to let it
+remain. There were many white lights all about--among them, her own
+would have but a small chance of being seen. But red was significant,
+conspicuous, indicative of danger, and that she was in grave danger she
+very well knew.
+
+She decided to first send the word "help." She knew that if the person
+receiving the message was a friend, he would at once ask where she was,
+since that would be to Mr. Stapleton and his party the most essential
+and important news she could give.
+
+On the other hand, were it to be received by one of the kidnappers, he
+would ask her, not where she was, but what was the matter.
+
+Painfully, fearful of mistakes, she deciphered the message which slowly
+flashed across the mile of night. "Where are you."
+
+Illustration: With trembling fingers she spelled out her reply, giving
+the address and adding, "Come quick!"
+
+With trembling fingers, she spelled out her reply, giving the address
+and adding, "Come quick." When she got the answer, "Will come at once,"
+she felt that there was still a chance that the boy might be saved. Then
+came the request for her name. She gave this impatiently. What
+difference did it matter, so long as they came quickly.
+
+She hastily lighted a candle which stood upon the table, then cast about
+her for some means whereby she might prevent the black-bearded man and
+his companion from entering the room, in case they should return before
+help arrived. There was one thing, of course, that she could do,
+barricade the door.
+
+But, with the exception of the table and the light iron bed, there was
+nothing with which she could hope to secure it. Suddenly her eyes fell
+upon the great plaster centaur. It was a figure such as one might see in
+any art gallery or museum. It stood upon a plaster slab some six inches
+thick, which in turn rested upon a low wooden base. The figure was at
+least five feet high--a horse with a human torso and head. She knew that
+if she could jam this in front of the door, securing it in place with
+the bed and table, she might prevent the kidnappers from entering for
+some little time; long enough, she hoped, to insure the arrival of the
+police before they had succeeded in breaking in.
+
+She wondered if she could manage to move the thing. At first sight, it
+seemed impossible, and yet the base might by chance be fitted with
+rollers or casters. She rushed over to the figure and began to tug at it
+with all her strength.
+
+She needed but a moment to discover that she could not possibly move it;
+but as she bent over it, her head close to its side, she heard something
+which made her start with sudden joy.
+
+It was the low sobbing of a child--the same moaning sound which she had
+heard from time to time ever since she had first entered the room.
+
+At times the sound had appeared to come from afar off; at others, it had
+seemed to be close at hand, as though originating at some point in the
+very air about her.
+
+All of a sudden the truth came to her like a flash. The child was
+concealed within the hollow body of the statue. The thing seemed so
+simple, so apparent, that she wondered that it had not occurred to her
+before.
+
+She gave up her attempt to barricade the door, and began feverishly to
+look for the opening in the plaster cast through which the child must
+have entered.
+
+It took but a few moments to find it. The whole side of the horse's body
+had been sawed free, by two longitudinal cuts, one along the back, the
+other along the belly, and two similar cuts, at the shoulder, and the
+flank. Heavy strips of canvas, glued across the lower cut, on the under
+side of the horse's belly, served as hinges, and were not visible from
+above.
+
+She inserted the blade of a modeling tool which she caught up from the
+table, in the upper longitudinal cut, and pried the plaster side of the
+horse free. It fell heavily toward her, disclosing a long narrow
+opening; the interior, in fact, of the statue, where lay, upon a sort of
+bed made of an old comfort, the missing son of Mr. Stapleton.
+
+The boy, who had evidently until a moment before been asleep, gazed up
+at her in surprised alarm. For over two weeks, now, he had been kept
+from his parents, made to move about from place to place, frightened by
+strange men. He had come to expect the unusual, the terrifying, and it
+was a scared little face that looked appealingly up at the girl as she
+bent over him.
+
+For the time being she forgot the dangers which surrounded them, in her
+joy at the discovery of the boy. It had come so suddenly, so
+unexpectedly. If she could only escape, now, with the child, nothing
+else would matter in the least. And between her and freedom there lay
+but the thickness of a single door, and yet it seemed that she could not
+pass it.
+
+She lifted the child from his hiding place and stood him upon the floor,
+then quickly swung the heavy slab of plaster back into position. At
+least, she reasoned, the kidnappers, when they returned, should not at
+once learn that their captive had escaped.
+
+She knew that the hiding place had been but a temporary one, a means
+whereby the child might be kept out of sight during the day in case
+strangers should happen to enter the room. As soon as the kidnappers
+returned, they would, she realized, spirit the child away to some more
+secure retreat.
+
+She went to the door and again shook it frantically, pulling at the knob
+with all her strength, without producing the slightest result. The lock
+was evidently a strong one--the door held firm and unyielding, though
+she threw against it her entire weight.
+
+Evidently there was no hope of escape here. Then she again bethought
+herself of the window. For a moment she gazed out into the darkness. The
+pavement was thirty feet below. No one was in sight. How could she ever
+reach the ground, with the child as well, even if she had possessed a
+rope? The thing was impossible.
+
+Clearly there was nothing to do but wait. Possibly the assistance she
+expected from her friends, or the police, would arrive very soon--surely
+she could in some way keep the kidnappers occupied until then!
+
+And suddenly she realized that the time had come. She heard the door of
+the house close softly, and upon the stair the sound of mounting
+footsteps.
+
+Which was it, the police, or the kidnappers? The latter, she felt
+morally certain, since the former, in their haste to rescue the child,
+would beyond any question have arrived in an automobile, and at top
+speed.
+
+The newcomers were mounting the stairs in a leisurely manner, as though
+free from any anxiety. Grace heard them pause for a moment on the first
+landing, then start up the second flight of stairs. It seemed to her out
+of the question, to stand in the middle of the room and await their
+entrance. At least she could postpone the fatal moment a little while,
+by hiding, with the boy, in the closet. She stepped into it, the child's
+hand in hers, and drew the door shut, just as the two men entered the
+room. On her way, she hastily blew out the candle.
+
+They were the same two men that she had seen before,--the black-bearded
+man, now without his beard, and the artist, Durand. She saw this, as
+soon as the latter had relit the candle. She wondered if he would notice
+that the wick was still warm. Evidently he did not; for they threw
+themselves into chairs, lit cigarettes, and began to talk.
+
+"Now we can speak freely," said Durand. "How did things go?"
+
+"I got the money--gave the blue signal, and expected to be halfway to
+Brussels by now. What nonsense is this about a red light?"
+
+"It is no nonsense, I assure you. I saw it with my own eyes, as plain as
+day."
+
+"Then François must have made a mistake, or else he has been placed
+under arrest--the latter, no doubt. Now the question is, What shall we
+do? I think we ought to get out of Paris as soon as possible. It isn't
+safe to stay here." He looked about him nervously.
+
+"Why not? You didn't telephone Monsieur Stapleton this address, did
+you?"
+
+"No, naturally not."
+
+"Then I don't see but what we are quite safe. No one knows the child is
+here."
+
+"Then you don't intend to give him up?"
+
+"Not yet. I must first find out whether or not François is in trouble."
+
+"Let him look out for himself."
+
+The older man frowned. "Since when, my friend," he asked, "have I been
+in the habit of deserting my comrades? François must go free, or Mr.
+Stapleton does not get his boy. That's flat. The first thing is to send
+his father something that will let him see that we mean business."
+
+"We've got to be sure about François, first."
+
+"I'll find that out, tonight. My plan is this. We must first get the
+child away to Lavillac's place. This is too unsafe, here. Anyone might
+come in."
+
+"They'd have difficulty in finding the hiding place." The younger man
+grinned.
+
+"That's all very well; but the other place is safer. And
+then--Lavillac's woman can look after the brat while we are away. What a
+pity François had to get into a mess at the last moment! I hoped to be
+rid of the boy, by now." The older man rose and began striding up and
+down the room.
+
+"Well," he said at length, sharply, "we might as well get along. I move
+that we wrap the boy in a coat, take him down to the car, run quickly
+out to Lavillac's place, leave him there, and start for Brussels at
+once. The rest we can do by 'phone. François set free--the boy the same.
+Meanwhile, we've got to show this man Stapleton we mean business; so
+we'd better arrange to send him one of the kid's hands at once. If we
+don't, he'll have the whole Paris police force after us."
+
+"All right. I'll get him out." He strode quickly over to the statue,
+pulled out the side, and gazed blankly into the empty space before him.
+
+"Sacré! The child's gone!" he exclaimed, excitedly. "Somebody has been
+here--in this room--since I left it, half an hour ago."
+
+"The door was locked."
+
+"I know; but somebody's been here, nevertheless, for the child is
+gone."
+
+"He may not be gone, Durand. It is true that he is no longer in the
+house; but he may be in the room, for all that. Search the closet."
+
+The man named Durand stepped quickly to the closet door. "Not much
+chance," he grumbled. "And if the police knew that he was here, and have
+spirited him away, they may even now be waiting to spring a trap of
+which you and I are the rats. For all we know the place is surrounded at
+this very moment."
+
+"Then the sooner we get away from it the better. Search the closet. If
+he's not there, we'd better make tracks for the frontier as quickly as
+possible. We can do nothing more without the child. François will have
+to look out for himself."
+
+Durand went impatiently up to the closet door and flung it open, then
+both he and his companion recoiled in surprise as Grace stepped out,
+holding the child by the hand.
+
+"Mon Dieu!" gasped the two men in unison.
+
+The one who had worn the black beard was the first to recover himself.
+"Quick!" he cried, motioning toward Grace. "The woman is a detective.
+Tie her up, and let's get away at once. No doubt she has sent word to
+her friends. We can't afford to stay here another minute." He seemed
+greatly excited and, rushing to the window, inspected the silent street
+below.
+
+Durand, meanwhile, had thrown himself upon the girl, seized her hands,
+and with a quick motion had secured them with a bit of cord he snatched
+from within the closet.
+
+She offered no resistance, made no outcry. Both seemed equally useless.
+The boy stood by, watching the scene in childish wonder. So many queer
+things had happened to him, however, during the past few days, that he,
+too, remained silent.
+
+In a moment the older man withdrew his head from the window, rushed to
+the closet, and drawing out a long gray coat, wrapped it about the
+child. "You will come along with us, Mademoiselle," he said sternly.
+"Make no attempt to escape, if you value your life."
+
+"But what do we want with her?" the younger man asked, impatiently.
+
+"You fool! Would you leave her here, to give our description to the
+police? It would mean certain capture in a few hours. This woman has got
+to be put where she can do no harm until we are safely over the
+frontier. It may be wiser to silence her altogether. We'll decide about
+that when we reach Lavillac's. The first thing is to get out of this
+house without losing a moment's time. Come!" He started for the door.
+
+As he did so, Grace heard, far off, the steady throbbing of an
+automobile. She felt a wave of hope sweep over her. It might be her
+friends, coming to her assistance. If so, they might yet arrive in time.
+
+The two men evidently also heard the sound. "Hurry--hurry!" the older
+one urged, as they began to descend the stairs. "They may be on us at
+any moment. Go out the rear way."
+
+Grace heard the sounds of the approaching automobile growing more and
+more distinct. In another minute it would stop before the door of the
+house. But in that minute her captors would not only have been able to
+descend the stairs, but would already be making good their escape
+through the garden at the rear of the building.
+
+She must do something, she knew, to prevent this; but what--what? Bound
+as she was, how could she hope to prevent the escape of these men. She
+looked ahead of her, to where, a step or two in advance, the man of the
+black beard was hastily descending the stairs, the boy firmly held in
+his arms. Behind her came his companion, candle in hand, close at her
+heels.
+
+They were within half a dozen steps of the lower hall. From this she
+could see a dark passageway, leading to the rear of the house. Already
+the noise of the automobile without told her that it was stopping at the
+door. She heard the sound of rapid footsteps on the sidewalk; yet
+realized that, before her friends could break in, their quarry would
+have flown.
+
+Without a moment's hesitation she sprang forward, throwing her whole
+weight upon the man in front of her.
+
+The sudden shock, as she precipitated herself upon his shoulders, threw
+him off his balance, and he pitched forward headlong into the hallway
+below. The two of them, together with the child, rolled in a tangled
+heap to the floor. The second man, candle in hand, stopped on the stairs
+and gazed helplessly down, not realizing for a moment what had happened.
+
+"Help! Help!" Grace screamed at the top of her voice, as she struggled
+to regain her feet, and at the same moment there came the sound of heavy
+blows upon the front door.
+
+The man who had been carrying the child rose to his feet with an oath,
+just as his companion joined him. He turned on Grace with a howl of
+fury, and struck her a quick blow in the face. She had a confused vision
+of fleeing men, the dancing light of a candle, a rush of fresh air, and
+then all was blotted out in a wave of oblivion.
+
+
+
+
+CHAPTER XIX
+
+
+The startling and dramatic entrance of Richard Duvall into Mr.
+Stapleton's library, ending with his announcement of the whereabouts of
+the kidnapped child, and his subsequent collapse, threw the entire party
+into confusion.
+
+Mrs. Stapleton started up with a scream, her overwrought nerves no
+longer able to resist the frightful strain under which she had for so
+many days been laboring.
+
+Her husband, who had completely forgotten the detective's presence in
+the house, in his anxious vigil at the telephone, called out instantly
+to one of the servants, ordering him to tell François to bring his
+automobile to the door.
+
+Monsieur Lefevre, accompanied by Vernet, sprang quickly to Duvall's
+assistance. The Prefect felt that, if the latter's statement was
+correct, he had won out in the long duel for the honor of recovering the
+kidnapped child; but no consideration of this nature could make him any
+less concerned for the detective's welfare, or any the less thankful
+that, no matter by whose efforts, the missing child had at last been
+located. He had hoped that to Grace Duvall would ultimately fall the
+prize of success; but these things were, after all, of no serious
+weight, compared with the great fact, that the success had at last come.
+
+Assisted by Vernet, he placed Duvall upon a couch, and called for
+brandy, and a basin of cold water.
+
+In a few moments, under Vernet's skilful ministrations, the detective's
+wound had been washed and temporarily bound up, and he had been restored
+to consciousness. A little of the brandy soon served to dispel his
+faintness. He declared himself ready to accompany the expedition to
+Passy.
+
+The Prefect endeavored to dissuade him; but to no purpose. The message
+which he had received in the chauffeur's room, to the effect that the
+person calling for help was Grace Duvall, his own wife, seemed so
+mysterious, so utterly inexplicable to him, that he could conceive no
+reasonable explanation for it. There was but one thing to do,--to go
+himself and sift the matter to the bottom. He did not expect to find
+Grace there, and yet--what else could the message mean?
+
+Just as he staggered to his feet, with the announcement that he would
+accompany the party to Passy, two of the servants rushed into the
+library, and with scared faces announced that François lay, bound and
+unconscious, on the floor of his room. Mr. Stapleton looked quickly at
+Duvall.
+
+"It's all right, Mr. Stapleton," exclaimed the detective. "The fellow is
+one of the gang." He turned to Monsieur Lefevre. "You'd better have him
+placed under arrest at once. And if your car is here, we'll use that,
+instead of Mr. Stapleton's. There's not a moment to be lost."
+
+"By all means. My automobile is at the door. Vernet," he turned to his
+assistant, "have one of your men take charge of this fellow François at
+once. We must set out immediately."
+
+Mr. Stapleton took his wife in his arms, and embraced her tenderly.
+"Don't worry, dear," he said. "I'll be back with the boy, inside of half
+an hour. Come along!" he shouted to the others, as he made for the door.
+"No time to waste now."
+
+In a few moments the entire party, consisting of Mr. Stapleton, Duvall,
+Monsieur Lefevre, Vernet, and the Prefect's chauffeur, were driving
+toward Passy at a rate which set at naught all speed regulations and
+sent the few pedestrians who happened to cross their path scampering to
+the sidewalk for safety.
+
+Duvall explained, as they went along, the mysterious messages which he
+had received by flashlight. No one understood them but Monsieur Lefevre.
+He gave a great sigh of relief. The continued and unexplained absence of
+Grace had alarmed him greatly. Now he began to understand the reasons
+for it. That part of Duvall's story which spoke of haste, the appeal for
+prompt assistance, made him look grave. He leaned over to his chauffeur
+and urged him to even greater speed.
+
+The trees and houses along the Avenue Kleber, and later the Rue
+Franklin, swept by the speeding machine in a whirl of dust. In what
+seemed an incredibly short time the automobile dashed into the Rue
+Nicolo, and thundered up to No. 42.
+
+Vernet was the first to ascend the steps of the house, closely followed
+by Duvall and the others of the party. As they reached the front door,
+and rapped loudly, they all heard a sudden commotion within, followed by
+cries and shouts and a fall. Instantly all four threw their combined
+weight against the door, shattering the lock and bursting it in.
+
+The semidarkness showed a terrifying spectacle. On the floor lay a
+woman, unconscious, clutching in her arms a child, trapped in a long
+gray coat. Down the dark hallway leading to the rear of the house dashed
+the figures of two men. One of them turned, as the attacking party
+entered, and hurled the lighted candle which he bore full into their
+faces. The entire scene was instantly plunged into darkness.
+
+The momentary light of the candle, however, had been sufficient to send
+a thrill of joy through at least one of the entering party. Mr.
+Stapleton recognized, in the white and tearful face of the child, his
+kidnapped boy, and, stooping, raised him tenderly in his arms.
+
+Duvall, not knowing whether the unconscious woman was the supposed agent
+of the police, Mademoiselle Goncourt, or Grace, his wife, lifted her in
+his arms and carried her out into the air.
+
+Vernet, followed by the Prefect, and the chauffeur, who had at once
+joined them, dashed fearlessly along the dark passage by which the two
+men were attempting to escape.
+
+There was a crash, as the rear door was burst out, followed by a volley
+of shots as Vernet opened upon the fleeing men with his automatic
+revolver.
+
+In a moment the affair was over. The foremost of the two men crumpled up
+before he had taken half a dozen strides through the garden, and his
+companion raised his hands and surrendered, begging for mercy. Within a
+few moments he was handcuffed, and Vernet, bending over his wounded
+companion, was directing the chauffeur to summon an ambulance at once.
+
+Monsieur Lefevre returned hastily to the street. His sole concern now
+was for Grace. He prayed fervently that no serious harm had befallen
+her, and realized that Duvall was likely to resent bitterly the
+deception which has been practised upon him.
+
+The latter, however, was in no mood for recriminations. No sooner had he
+carried his unconscious burden to the street, when Grace opened her
+eyes, threw her arms about his neck, and kissed him.
+
+"Richard--Richard!" she cried, happily. "I'm so glad--so glad!" then
+rested content in his arms.
+
+The detective's brain was in a whirl. In no possible way could he
+account for the presence here, in Paris, under such tragic and
+inexplicable circumstances, of the wife whom he had left, so short a
+time before, peacefully sitting on the rosecovered porch of their home
+in Maryland. The thing seemed incredible, unbelievable; yet here was
+Grace, with her soft arms about his neck, her kisses on his lips, to
+prove its reality.
+
+He looked at Monsieur Lefevre dully as the latter joined them upon the
+sidewalk, but could say nothing.
+
+"It seems," remarked the Prefect, with a grave smile, "that not only has
+Mr. Stapleton found his boy, but you have found your wife."
+
+Duvall frowned. "What is she doing here?" he asked.
+
+"We will speak of that later, my friend," observed Lefevre, quietly.
+"Just at present I propose that we return to Mr. Stapleton's without a
+moment's delay. Her heart is breaking with anxiety." He took Grace's arm
+and assisted her to enter the automobile, where Mr. Stapleton had
+already preceded them with his son. "It is to you, my dear child," he
+said to Grace, as she sunk weakly back upon the cushioned seat, "that
+Mrs. Stapleton will owe all her happiness."
+
+It was a cheerful party that broke in upon the banker's wife a short
+time later. Duvall, under the stimulus of Grace's presence, had
+completely forgotten his wound; while Grace, who had been but
+momentarily stunned by the blow which the kidnapper had given her, was
+radiant with joy at once more feeling her husband's arms about her.
+
+Monsieur Lefevre carried them both off to his house, as soon as the boy
+had been restored to his mother. The happiness of the banker's reunited
+family was too great to permit them to be even mildly interested in the
+affairs of Richard Duvall and his wife, and they, too, wished to be
+alone. It seemed to them both as though ages had passed since they had
+seen each other; they could scarcely realize that it had been but a
+little over two weeks. Richard especially seemed unable to grasp the
+truth of the situation. He plied Grace with numberless questions, and
+could scarcely believe that he had actually been within arm's length of
+her on at least four different occasions during the past week without
+knowing it.
+
+Monsieur Lefevre advised him to leave the whole matter until the next
+day. "You should be proud of your wife, Monsieur," he said, gravely.
+"But for her, I doubt if Monsieur Stapleton would ever have seen his boy
+again. And that reminds me," he smiled mischievously, "that I have won
+that little bet. It was Mademoiselle Goncourt, of my office, that
+recovered the lost child."
+
+"I think the honors are pretty evenly divided, Monsieur," laughed Grace,
+happily, as she pressed her husband's hand. "Don't forget that if
+Richard hadn't gotten my message, all my work would have gone for
+nothing."
+
+"Suppose we call it a draw, then," said the Prefect. "All in the family,
+as you Americans say. And to show that I am not prejudiced, one way or
+the other, I suggest that you both, with Mr. and Mrs. Stapleton, dine
+with me tomorrow evening. There are many points connected with this case
+which are by no means cleared up, and we should talk them over. Although
+we have secured the missing child, and three of the kidnappers, we do
+not yet know how the child was stolen, or whether the nurse, Mary
+Lanahan, is innocent or guilty of any part in his mysterious
+disappearance in the Bois de Boulogne. I confess that I have all along
+considered her guilty, and am inclined to order her arrest at once."
+
+"It will be useless, Monsieur," remarked Duvall, quietly. "She is
+entirely innocent."
+
+"You mean that she knows nothing of how the boy was spirited away?"
+
+"Nothing!"
+
+"Mon Dieu! Then the thing may forever remain a mystery."
+
+"Not at all. It is simple enough."
+
+Monsieur Lefevre turned to him with a look of inquiry. "You mean, then,
+that you have solved it?"
+
+"I do."
+
+"Then may I ask that you will be good enough to explain it at once?"
+
+Duvall laughed. "Monsieur Lefevre," he said, "I have a splitting
+headache, a bad wound in my cheek, and a burning desire to spend the
+next two hours talking to my wife." He drew Grace toward him, and put
+his arm through hers. "I am very much afraid that the explanation of
+the disappearance of Mr. Stapleton's boy will have to be put off until
+tomorrow."
+
+Monsieur Lefevre watched the two as they went, arm in arm, up the
+stairs.
+
+"Mon Dieu!" he said softly to himself. "They are just as much in love
+with each other as ever."
+
+
+
+
+CHAPTER XX
+
+
+"I must confess," remarked Monsieur Lefevre, as he sat with Mr.
+Stapleton and Duvall over their after dinner cigars the following
+evening, "that while the case as a whole appears simple enough to me,
+there are one or two points that I fail to understand."
+
+"There are a great many that _I_ fail to understand," exclaimed the
+banker, chewing reflectively on his cigar. "However, now that the boy is
+safe at home, it really makes very little difference."
+
+"On the contrary, Mr. Stapleton," remarked Duvall, "it makes a great
+deal of difference. For instance, I understand that you have discharged
+the nurse, Mary Lanahan."
+
+"Yes. You say that she is quite innocent of any part in the kidnapping
+of my boy; but the fact remains that I don't trust her. I am informed
+that she was married to that fellow, Valentin, this afternoon."
+
+Duvall smiled. "That was quite to be expected."
+
+"At one time," said Mr. Stapleton, "you believed this fellow Valentin to
+have been concerned in the plot."
+
+"Yes. That is true. My early investigations of the matter showed me at
+once that there was some understanding between these two, something
+which they were endeavoring to conceal. I did not at first understand
+the motive which actuated them. I thought it was guilt. In reality, it
+was love. Therefore I am not surprised to learn of their marriage." He
+gazed critically at his cigar for a time, in silence.
+
+"As matters have turned out, gentlemen," he resumed, after a few
+moments, "there is no cause for anything but congratulation on all
+hands. The child is recovered, the criminals are under arrest, the
+money--the hundred thousand dollars you paid out, Mr. Stapleton--was
+found on the kidnapper's person and returned to you."
+
+"Exactly. Nothing could be more satisfactory all around."
+
+"And yet," went on the detective, "I have never before taken part in a
+case in which I have done so little, in which I have been so uniformly
+unsuccessful."
+
+Mr. Stapleton raised his hand. "My dear Duvall," he began, "but for you,
+we should have been nowhere."
+
+"You are wrong, my friend. Had I kept out of the case altogether, your
+son would have been returned to you just the same. It is true that the
+men who kidnapped him would not have been caught, and your money would
+not have been returned to you; but the prime object which you sought,
+the recovery of your child, would have been realized in any event."
+
+"That is true," remarked the Prefect; "but, from the standpoint of the
+police, it is the detection and capture of the criminal that is desired,
+not the buying of him off. By insisting on that, Mr. Stapleton, you
+rendered our work extremely difficult."
+
+"So difficult, indeed," said Duvall, earnestly, "that but for the
+energy, the courage, the wit of a woman, all our plans would have
+failed. I refer to my wife. It is to her that all the credit in this
+affair is due."
+
+"By all means!" said Mr. Stapleton. "I could not fail to realize, when
+she told her story at dinner tonight, how much Mrs. Stapleton and
+myself owe her. I shall have something to say on the subject of our
+debt, as soon as the ladies rejoin us. But tell us, Mr. Duvall, a little
+more about the case, as you now understand it. I confess that I am
+becoming more and more interested. What, for instance, was the mystery,
+if indeed there was any, connected with the box of gold-tipped
+cigarettes?"
+
+Duvall smiled. "That, my dear sir, is in fact the crux, the starting
+point, of the whole affair." He settled back in his chair comfortably.
+"Otherwise the case was simple enough. Certain scoundrels steal a child,
+hold it for ransom, and frighten the parents into paying over a large
+sum. Nothing unusual in that. A clever scheme or two for turning the
+money over, and returning the child--simple, yet perfect enough to defy
+all attempts to foil them.
+
+"The real mystery lay in the utter absence of any clues which would
+throw light on the actual stealing of the child. In this respect the
+case was unique. A trusted nurse swears that the child has disappeared
+in broad daylight, without the slightest knowledge of how it was
+accomplished. Here we have a case so simple, so devoid of incident of
+any sort, that we are baffled at the very start by the impossibility of
+the thing. Yet the nurse is a woman of good reputation, honest, clearly
+telling what she believes to be the truth.
+
+"But a single clue existed upon which I could build the least semblance
+of a case. I refer to the half-smoked cigarette with the gold tip, which
+I discovered in the grass at the scene of the crime. Without that
+apparently trivial clue, the criminals would in all probability never
+have been captured at all."
+
+"But," exclaimed Mr. Stapleton, "I don't see how you make that out."
+
+"Nor I," observed the Prefect.
+
+"No. I suppose not. And yet, it is simple enough. That half-smoked
+cigarette and nothing else is the basic reason for the arrest of the
+three men now in your hands."
+
+Monsieur Lefevre smiled. "Be good enough," he said, "to explain."
+
+"Very well, I will. But first, let me indicate to you my course of
+reasoning. When I originally found the cigarette, I regarded it as of
+very small value, from the standpoint of evidence. It happened to be
+lying in the grass at the point where the crime occurred; but during
+the week or more which had elapsed between the stealing of the boy and
+my examination of the ground, a hundred people might have walked over
+the spot. I took it, because I realized that it _might_ have a bearing
+on the case, and I have learned to discard no clue, however trifling it
+may appear, until it has been proven valueless.
+
+"Now to go back to the cigarette, I observed at once that it was of
+American make, yet of such small size as to have been either used by a
+woman, or by a man of rather effeminate taste.
+
+"Now if the cigarette had been used by a woman, it meant one of two
+things. Either it was used by Mary Lanahan herself, in which case it
+apparently proved nothing, or by some other woman who was there with
+her, and who might have had a hand in the kidnapping.
+
+"On the other hand, if used by a man, it pointed clearly to the
+chauffeur, Valentin, for several reasons. He was a friend, a former
+lover, of the nurse. He had been discharged by Mr. Stapleton for
+dishonesty. He was, I had reason to know, of rather a weak and
+effeminate type. The cigarette was of American make, and he had but
+recently come from America. These things pointed to Valentin. The fact
+that the nurse was in love with him would cause her to shield him. I
+determined to try the matter out at once.
+
+"As soon as I returned to the house, therefore, I confronted her, and
+asked her if Valentin smoked gold-tipped cigarettes. I did this, not
+because I expected to get any reply of value, but because I wished to
+observe her manner, her face, when I flung the question at her.
+
+"She was greatly startled. She denied that Valentin smoked. Fifteen
+minutes later, she sent him a message to destroy the cigarettes.
+
+"I at once concluded that they were working together, and were both
+guilty, a conclusion in which, however much I was justified by the
+evidence, I was quite wrong.
+
+"Then came the attempt on the part of someone--the man with the black
+beard, I am told--to steal the cigarettes from Valentin. I learned that
+the man was followed to Mr. Stapleton's house.
+
+"This at once threw a new light upon the matter, although I will admit a
+confusing one. Someone else, besides the nurse, desired the box of
+cigarettes removed as evidence; someone, in fact, who belonged to, or
+had friends in, the house. Who could this be? I could think of no one,
+outside of Mary Lanahan herself, but the chauffeur, François."
+
+"Why did you first suspect him?" asked Mr. Stapleton.
+
+"Because he was the only person, besides the nurse, who was present at
+the time of the kidnapping. I did not abandon my suspicions of either
+the nurse or Valentin. I fully believed that they knew a great deal more
+about the affair than they admitted. But I became convinced that
+François, too, was in the thing. He had testified that he was asleep
+when the affair occurred. I concluded at once that he was lying.
+
+"At the first opportunity, therefore, I made a thorough search of his
+room, and found the box of cigarettes hidden in a clock on his mantel."
+
+"Ha! I did not know that," exclaimed the Prefect. "What were they doing
+there?"
+
+"I concluded that the fellow with the black beard who stole them from
+Valentin, in order to prevent their use as evidence against him, turned
+them over to François for a definite purpose."
+
+"And that purpose was?"
+
+"Their use in subsequent crimes of a similar nature."
+
+Mr. Stapleton and the Prefect gazed at Duvall in bewilderment. "Explain
+yourself, my friend," exclaimed the latter. "I confess I do not
+understand what you are talking about. Who, may I ask, really smoked the
+cigarette, the remains of which you found in the grass?"
+
+"Mary Lanahan," said the detective, with a smile.
+
+"The nurse! Name of a dog! Then I fail to see that the matter is of the
+slightest importance one way or the other."
+
+"On the contrary, Monsieur, it is of the greatest importance. May I ask
+whether you are, by any chance, familiar with the properties of an
+Eastern drug, made from hemp, and generally known as hashish?"
+
+The Prefect sat up suddenly, and clapped his hands to his knees. "Mon
+Dieu!" he exclaimed. "Now I begin to understand."
+
+"More than I do," said Mr. Stapleton.
+
+"The cigarettes were drugged, that is all," went on Duvall. "The men who
+planned this thing went to work very carefully. They ascertained,
+through François, that Mary Lanahan was in the habit, no doubt on the
+sly, of using cigarettes. I discovered the fact, myself, before I left
+New York. They also learned that she smoked the same brand as Mrs.
+Stapleton herself used. No doubt she helped herself from Mrs.
+Stapleton's supply. They therefore secured, also through François, a box
+of these cigarettes, and had them heavily drugged with hashish. The box
+of drugged cigarettes was substituted, later on, for her own."
+
+"But," exclaimed Mr. Stapleton, "how could Mary Lanahan swear that she
+turned away but a moment--that no one came near her?"
+
+"When Mary Lanahan testified that, she believed that she was telling the
+truth. The hashish had simply destroyed her conception of the passage of
+time."
+
+"Is that its effect?"
+
+"Yes. It produces a delightful languor, a stupor in which all
+realization of the passage of time ceases. Sometimes, to those who use
+the drug, it may apparently require hours to walk a few yards. To make a
+momentary movement of the hand may seem to take many minutes. On the
+other hand, in the stupor which the drug induces, hours may be spent in
+the contemplation of a flower, a bit of scenery, the page of a book,
+without any realization on the part of the user that more than a few
+seconds have elapsed. That is what happened to Mary Lanahan. She inhaled
+a few puffs of the cigarette, heavily charged with the drug; without
+knowing, of course, of its presence. She probably passed at once into a
+state of stupor which may have extended over fifteen minutes or more.
+She was not unconscious. She sat upon the grass, looking off toward the
+distant sky, in a waking dream, not unlike a trance, in which all the
+world about her--the world of sound, of movement--had simply ceased to
+exist. She was to all intents and purposes unconscious of what was going
+on about her. The kidnapper, whom I strongly suspect to be François,
+merely strolled up behind her, picked up the boy, and walked off with
+him."
+
+The detective's listeners looked at him in astonishment. Presently Mr.
+Stapleton spoke. "Why do you think it was François?" he asked.
+
+"Oh, for many reasons. Had he, on approaching, found the nurse not
+sufficiently under the influence of the drug, he could have pretended to
+wish to speak to her, on some trivial matter. Again, the child would go
+away with him of course without making an outcry, which he would
+probably not have done, with a stranger. There are other reasons. He no
+doubt took the boy to the road, and handed him to his confederates,
+passing in another car. The affair occurred, you will remember, in a
+little frequented part of the Bois.
+
+"The subsequent actions of Mary Lanahan are a trifle difficult to
+account for; but I suppose them to have been as follows: On slowly
+coming out of her stupor, and realizing that the boy was gone, she was
+terribly frightened. It had seemed to her but a moment since she turned
+away. She fears that the cigarette has made her drowsy--she has heard
+that they sometimes contain opium. She thinks she may have dozed off;
+but is not willing to admit it. Especially does she not want her
+employers to know that she uses cigarettes. She fears that such
+knowledge would cost her her place. It is not until later that she
+begins to suspect the cigarettes."
+
+"When is that?" inquired Lefevre.
+
+"Several days later, when she is supposed to have been poisoned. She was
+with Valentin at the time; although, on account of Mr. Stapleton's
+dislike for him, she feared to admit it. She smokes another of the
+cigarettes, while sitting on a bench with him, in the Champs Élysées.
+Suddenly she is taken ill--a frequent result of hashish, when taken in
+excessive doses, or by one otherwise nervously upset. Valentin takes the
+box, puts her into a cab, and goes to his room, where he leaves the
+cigarettes. No doubt, as she begins to feel ill, she discusses with him
+the possibility of the cigarettes having been poisoned. It is for that
+reason that she gives them to him.
+
+"Her sudden message to Valentin to destroy them arose from a fear that I
+would discover the part which they had played in the boy's loss. This
+would, she knew, not only cost her her place, but would make her, in a
+way, responsible for the entire affair. She feared Mr. Stapleton's
+wrath, and therefore both she and Valentin remained dumb, so far as the
+cigarettes were concerned.
+
+"They both, however, were all this time doing their best to find the
+child. Her message to Valentin, that she was suspicious of François,
+telling Valentin to watch him, arose no doubt from a realization that
+the box of drugged cigarettes had been substituted for her own by the
+chauffeur.
+
+"Valentin, acting on her advice, does watch François, as his presence
+clinging to the rear of the latter's car the other night has proved. He
+tells me, today, that François did not take his car to the garage that
+night at all. The men there who so testified lied, at his request,
+supposing it merely an excuse to cover a joy ride.
+
+"François, not wishing that the drugged cigarettes should remain in the
+nurse's hands as evidence against him, evidently made an attempt to
+recover them, discovered that she had turned them over to Valentin, and,
+being watched himself, sent word of the matter to his confederate, the
+fellow who went about in the black beard. He must have been admitted to
+Mr. Stapleton's house that night by François himself.
+
+"I came to the conclusion, early in the course of my investigations,
+that the cigarette, the end of which I had found in the Bois, had been
+smoked by Mary Lanahan, and I so told Mr. Stapleton."
+
+The banker nodded. "Yes," he said; "but you did not then say anything
+about the hashish."
+
+"I was not certain of it. I intended to have the fragment I had found
+analyzed. When I discovered the cigarettes in François' room, you will
+remember that I took one of them. I smoked that cigarette, before going
+to bed that night. It produced exactly the sensations that Mary Lanahan
+must have felt. I floated away in the land of dreams for over half an
+hour, and came to with no recollection whatever of the passage of time.
+It is a remarkable drug, but an extremely dangerous one.
+
+"After that, the case became simple enough. I knew at once, beyond any
+question, that François was one of the kidnappers. My plans last night
+would have worked perfectly, but for the chauffeur's accidental
+discovery of me, hiding in the closet. Had that not happened, the boy
+would have been returned, according to program, and François I had
+safely in my hands."
+
+"But we wouldn't have got the others," laughed the Prefect. "You must
+thank your wife for that. Vernet has told me how the kidnappers
+outwitted you at the Avenue Malakoff. The car from which the signal
+apparently was made contained a well known stockbroker, who knew nothing
+of the matter at all. He merely happened to be passing the Avenue
+Malakoff at the precise moment when the signal was given to François."
+
+"You are mistaken, Monsieur," observed the detective, quietly. "The
+signal was undoubtedly made from that car; not by Monsieur Lemaitre, I
+will admit, but by his chauffeur. He has admitted to Vernet that a
+stranger paid him fifty francs to do so, on the plea that it was some
+signal to a woman. The man knows nothing of the affair, beyond that."
+
+As he finished speaking, there was a ripple of laughter from the hall,
+and Mrs. Stapleton, Madame Lefevre, and Grace came in.
+
+"We have been debating a most important question," said Mrs. Stapleton,
+with an assumption of extreme gravity, "and we beg that you, Monsieur
+Lefevre, will be so good as to decide it."
+
+"What is this question so grave, Madame," inquired the Prefect, rising,
+with a smile. "I am all impatience to hear it."
+
+"The question is this, Monsieur Lefevre: Which deserves the greater
+credit for the recovery of my boy--Mr. Duvall, or his charming wife?"
+
+The Prefect stepped forward, placed one hand affectionately upon
+Duvall's shoulder, and with the other grasped Grace by the arm.
+
+"The question you propound, Madame," he said, looking from the detective
+to his wife with a smile, "is easily answered. The credit belongs
+equally to both. And that, my children, is as it should be. This affair,
+so happily terminated, has taught me one important lesson. It is this:
+The husband and the wife should never be in opposition to each other.
+They must work together always, not only in matters of this sort, but in
+all the affairs of life. I attempted a risky experiment in allowing
+these two dear friends of mine to attack this case from opposite sides.
+But for some very excellent strokes of luck, it might have resulted most
+unhappily for all concerned. Hereafter, should Monsieur Duvall and his
+wife serve me, it must be together, or not at all." He turned to Grace.
+"I feel that I owe you both a great debt, my child, for having once
+again so rudely interrupted the course of your honeymoon. What
+reparation can I make? Ask of me what you will."
+
+"Anything?" inquired Grace, laughing.
+
+"Anything." The Prefect bowed gallantly.
+
+"Then I demand your promise, Monsieur, to visit us at our place in
+Maryland, before the end of the year."
+
+"That," exclaimed the Prefect, as he bent and kissed her hand, "would be
+the most delightful way of paying a debt that I could possibly
+imagine."

+
+1.A. By reading or using any part of this Project Gutenberg-tm

+and accept all the terms of this license and intellectual property
+(trademark/copyright) agreement. If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or destroy
+all copies of Project Gutenberg-tm electronic works in your possession.

+
+1.B. "Project Gutenberg" is a registered trademark. It may only be

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

+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:

+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges. If you are redistributing or providing access to a work

+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT

+refund. If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund. If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+

+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive

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

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

+<h2>CHAPTER I</h2>
+
+
+<p class="cap extraspacetop">THE big, mud-spattered touring car, which
+for the past hour had been plowing its
+way steadily northward from the city of
+Washington, hesitated for a moment before the
+gateway which marked the end of the well kept
+drive, then swept on to the house.</p>
+
+<p>A man, stoutly built, keen of eye, showing haste
+in his every movement, sprang from the machine
+and ascended the veranda steps.</p>
+
+<p>"Does Richard Duvall live here?" he inquired,
+curtly, of the smiling old colored woman who
+came to the door.</p>
+
+<p>"'Deed he do, suh. Does you want to see
+him?"</p>
+
+<p>"Yes. At once, please. Tell him it is most
+important. My name is Hodgman."</p>
+
+<p>The servant eyed him with cool disfavor. "Set<span class='pagenum'><a name="Page_4" id="Page_4">[4]</a></span>
+down, suh," she remarked stiffly. "I'll tell him
+you is here."</p>
+
+<p>The caller watched her, as she disappeared
+into the house, then cast himself impatiently into
+a chair and lit a cigar.</p>
+
+<p>He paid no attention to the attempts of two
+clumsy collie puppies to attract his favorable
+notice, but contented himself with making a quick
+survey of the wide comfortable veranda, with its
+big roomy chairs, the wicker table, bearing a
+great jar of red peonies, the smooth green lawns,
+swept by the late afternoon sun.</p>
+
+<p>"Fine old place," he muttered to himself.
+"Wonder if I can persuade him to go?"</p>
+
+<p>As the car which had brought Mr. Hodgman
+on his hasty trip from Washington dashed up to
+the front of the house, Grace Duvall, looking
+very charming in a blue linen dress, was just approaching
+it from the rear.</p>
+
+<p>She held a pair of shears in her hand, and her
+apron was filled to overflowing with hundred-leaf
+roses. "Dick&mdash;oh, Dick!" she called, as she came
+down the long avenue of syringas and lilacs which
+led to the house. "The sweet peas are nearly
+ready to bloom."</p>
+
+<p>Richard Duvall, looking as simply pastoral as
+though he had never tracked an international<span class='pagenum'><a name="Page_5" id="Page_5">[5]</a></span>
+crook to cover, raised his head from the flower
+bed, in which he had been carefully setting out
+circle after circle of geranium plants.</p>
+
+<p>"Are they?" he laughed. "That's good. Now
+all we need is a few good hot days." He gathered
+up his trowel and rake, and started toward
+the barn.</p>
+
+<p>Grace put her arm through her husband's and
+together they strolled across the springy green
+turf, their faces smiling and happy. The honeymoon
+showed no signs of waning.</p>
+
+<p>This lovely old country place, in southern
+Maryland, had been one of Richard Duvall's
+dreams for many years, and after his marriage
+to Grace Ellicott, in Paris, it had become hers,
+as well. It was but a short time after their return
+to America that they decided to make it a reality.</p>
+
+<p>Grace had encouraged her husband in the plan
+of giving up, for a time at least, his warfare
+against crime, his pursuit of criminals of the
+higher and more dangerous type, and had persuaded
+him to buy the farm which had once belonged
+to his mother's people, and settle down to
+the life of a country gentleman.</p>
+
+<p>His office was still maintained, under the able
+direction of one of his assistants, but Duvall gave
+little or no attention to its affairs. He was glad<span class='pagenum'><a name="Page_6" id="Page_6">[6]</a></span>
+to withdraw, for the first time in over nine years,
+from active work, and devote his energies to early
+potatoes, prize dogs, hunters, and geranium plants&mdash;and,
+above all, to the peaceful enjoyment of his
+honeymoon, and the making of Grace the happiest
+woman in the world.</p>
+
+<p>She, on her part, found in their present situation
+all the joys of existence for which she had
+longed. With little or no liking for the monotonous
+round of society and its duties, and a passionate
+love of nature, she found in the many
+and complex duties of managing her part of their
+extensive estate a far greater happiness than any
+which city life could have offered her.</p>
+
+<p>The considerable fortune which her husband's
+clever work while in Paris had restored to her,
+had been safely invested in well paying securities,
+and she found her greatest joy in utilizing at
+least a part of her income in beautifying their new
+home.</p>
+
+<p>Richard had steadily refused to make any use
+of the money. It was a matter of pride with him,
+that his own savings had enabled him to purchase
+the property; but when Grace proposed to build
+an addition to the house, to provide him with a
+more comfortable library and work room, or
+insisted upon having the roads throughout the<span class='pagenum'><a name="Page_7" id="Page_7">[7]</a></span>
+place elaborately macadamized, he was obliged
+to submit to her wishes. In this way, they planned
+and built for the future, together.</p>
+
+<p>The farm was a large one, comprising some
+two hundred acres, and the old stone house surrounded
+by white oaks and tulip poplars had once
+been a show place, before the declining fortunes
+of its former owners had caused it to fall into a
+state of mellow and time-honored decay. Now
+all was changed. Grace, with the able assistance
+of old Uncle Abe Turner, a relic of ante bellum
+times, spent hours daily in bringing order out of
+the chaos of tangled myrtle and ivy, overgrown
+box and hedge, thickets of syringa and lilac bushes
+and weed-grown lawns.</p>
+
+<p>It was a gigantic task, yet a joyous one&mdash;as it
+ever is, to those who came to it with the love of
+nature in their hearts. To Grace, the plants and
+shrubs, the great strong oaks, the towering poplars,
+each seemed to have a distinct personality.
+Under her energetic hand, the place once more
+took on the aspect of well kept and orderly beauty
+which was such a contrast to its former down-at-the-heels
+appearance. It seemed as though the
+growing things realized the personal interest she
+took in them, and responded as they never respond
+to the ignorant or unsympathetic.<span class='pagenum'><a name="Page_8" id="Page_8">[8]</a></span></p>

+<p>Richard was concerned with his fields of timothy
+and clover, his early corn, his berries and fruit
+trees, to say nothing of his collies, his prize cows
+and Kentucky horses. In such a life, time never
+hangs heavy&mdash;he was busy studying, planning,
+working, from morning to night, and his active
+mind soon convinced his capable overseer and the
+farm hands as well that, although Richard Duvall
+was by no means a professional farmer, he could
+still show them a thing or two when it came to
+the rotation of crops, the spraying of fruit trees,
+or the proper treatment of worn out soils. These
+were aspects of farming life which the hide-bound
+conservatism of the local farmers caused them to
+jeer at, as newfangled notions gotten from books.
+Later when they saw the man who farmed with
+his head as well as his hands gather in two bushels
+where they had barely been able to secure one,
+they began to sit up and take notice.</p>
+
+<p>"I got the new hedges all set out today," Grace
+went on, as she patted her husband's rather grimy
+hand. "They will be charming, against the gray
+stone of the wall. But we must have new gate
+posts. The old ones are likely to tumble into the
+road at any moment."</p>
+
+<p>"I'll have Martin come out tomorrow and look
+them over. There's plenty of stone&mdash;down in the<span class='pagenum'><a name="Page_9" id="Page_9">[9]</a></span>
+lower pasture. Why not carry the wall right
+along the whole front of the property? It ought
+not to cost a great deal."</p>
+
+<p>"We will. And I'm going to have a new spring
+house built, too. The old one is falling to
+pieces." She looked up at her husband as he deposited
+the rake in the tool room and they started
+up the shaded walk toward the house. "Aren't
+you glad, Dick, that we're <i>alive</i>?"</p>
+
+<p>He pressed her arm. "Well&mdash;I should say
+so, little girl! Why do you ask me that?"</p>
+
+<p>"Oh&mdash;you know what your friends all said&mdash;that
+a man might as well be dead, as buried out
+here in the country. I think they are the ones
+who are not alive&mdash;cooped up in the city. Don't
+you?"</p>
+
+<p>Richard nodded. He was thinking for the
+moment of his former active life&mdash;when some
+battle of wits with a noted crook had kept him
+sleepless for nights. "It's&mdash;rather different," he
+laughed. "Isn't it?"</p>
+
+<p>"Yes&mdash;and much better. Don't you think so,
+dear? You wouldn't want to go back to it&mdash;would
+you?"</p>
+
+<p>"Not for anything in the world," he assured
+her, as he swept the newly seeded lawns with a
+contented glance. "I liked the other life, of course&mdash;the excitement,<span class='pagenum'><a name="Page_10" id="Page_10">[10]</a></span>
+the danger of it; but this is
+better&mdash;much better. Here, Don!" he called to
+a graceful collie which was barking vociferously at
+some distant vehicle in the road. "Come here
+and be quiet." He turned with Grace to the great
+vine-covered side porch and sank contentedly into
+a rocking chair. "Well, little girl&mdash;it's been a
+busy day, and I'm tired. We got the early rye
+all cut on the lower field today. Guess we'll put
+in late potatoes, after it's plowed. Here, Don&mdash;come
+back here! What's the matter with you?"
+He rose and whistled to the dog, which was bounding
+across the lawn in the direction of the road.
+"Come back, I say!"</p>
+
+<p>"It's someone coming in," said Grace, uneasily.
+"In a machine. I wonder who it can be?"</p>
+
+<p>"Possibly Hudson, the veterinary. He was
+coming today, to look at that heifer."</p>
+
+<p>"He hasn't a machine like that. This is a big
+touring car." She turned to her husband.
+"Hadn't you better go in and fix up a bit, Dick?
+It may be company."</p>
+
+<p>Duvall laughed. "If it is, they'll have to take
+me as I am," he said; then again called to the dog.</p>
+
+<p>A moment later the servant, who had interviewed
+the caller at the front door, came out to
+the side porch. "Gentleman to see you, Mr. Duvall,"<span class='pagenum'><a name="Page_11" id="Page_11">[11]</a></span>
+she said. "Seems to be in a powerful
+hurry, too."</p>
+
+<p>"All right, Aunt Lucy," said Duvall as he made
+his way to the front of the house.</p>
+
+<p>"Is this Richard Duvall?" the visitor asked,
+in a quick, almost peremptory tone, as the detective
+joined him.</p>
+
+<p>"Yes. That is my name. What can I do for
+you?"</p>
+
+<p>The newcomer rose nervously from his chair
+and began chewing upon his half-smoked cigar.
+"Had the devil of a time to find you, Mr. Duvall."</p>
+
+<p>"You came out from Washington, I suppose,"
+remarked the detective, wondering what his visitor
+could want with him.</p>
+
+<p>"Yes. Got your address from Hicks, of the
+Treasury Department. He said you were about
+twelve miles out. I seem to have come about
+twenty."</p>
+
+<p>"Perhaps you went around by way of Laurel.
+It's much further, that way. What can I do
+for you, Mr.&mdash;&mdash;" He paused interrogatively.</p>
+
+<p>The man looked up at him quickly. "My
+name's Hodgman&mdash;Thomas Hodgman&mdash;of New
+York. I represent John Stapleton."</p>
+
+<p> <span class='pagenum'><a name="Page_12" id="Page_12">[12]</a></span>"John Stapleton, the banker?" asked Duvall,
+surprised.</p>
+
+<p>"Yes. You know him, don't you?"</p>
+
+<p>"Yes. Quite well. I handled a case for him
+once&mdash;some years ago. Why?" Duvall's face
+became grave. He began to realize that the interview
+was likely to become suddenly important.
+John Stapleton, the multi-millionaire banker, was
+not in the habit of sending messengers to anyone,
+without good reason.</p>
+
+<p>"So he said," went on Mr. Hodgman, resuming
+his chair. "That's why I'm here. He wants you
+to take another&mdash;"</p>
+
+<p>"Another?"</p>
+
+<p>"Yes. Another case. Quick."</p>
+
+<p>"It's quite out of the question."</p>
+
+<p>"Nonsense! This is important. Money's no
+object; name your own terms."</p>
+
+<p>"It isn't a question of terms, Mr. Hodgman.
+I have withdrawn, for the time being at least,
+from active professional work."</p>
+
+<p>"I know." The visitor flicked the ashes impatiently
+from his cigar and sought nervously in
+his pockets for a match. "That's what they told
+me at your office, in New York. Said you were
+on your honeymoon, and didn't want to be bothered."</p>
+
+<p><span class='pagenum'><a name="Page_13" id="Page_13">[13]</a></span>"That's true. I don't."</p>
+
+<p>"I told Mr. Stapleton that. He sent me to see
+you; said you might change your mind, when you
+heard about the case."</p>
+
+<p>"It is quite impossible. I do not care to take
+up any detective work at present."</p>
+
+<p>Mr. Hodgman fidgeted nervously in his chair.
+"You must listen to what I have to say, Mr.
+Duvall, at any rate. Mr. Stapleton would not
+hear to my returning, after seeing you, without
+having explained to you the nature of the
+case."</p>
+
+<p>Duvall leaned back, and began to fondle the
+long moist nose of the collie which sat beside his
+chair. "If you insist, Mr. Hodgman, I will listen,
+of course; but I assure you it will be quite useless."</p>
+
+<p>"I hope not. The case is most distressing.
+Mr. Stapleton's only child has been kidnapped!"</p>
+
+<p>"Kidnapped!" Duvall sat up with a start,
+every line of his face tense with professional interest.
+"When? Where?"</p>
+
+<p>"In Paris. The cablegram arrived this morning.
+I don't know the details. Mrs. Stapleton
+has been spending the winter abroad. Mr. Stapleton
+was to join her this month. She is living at
+their house in the Avenue Kleber, Paris. The<span class='pagenum'><a name="Page_14" id="Page_14">[14]</a></span>
+child was out walking with a nurse. It has been
+stolen. That's all I know."</p>
+
+<p>"When did it happen?"</p>
+
+<p>"Yesterday morning. Mrs. Stapleton did not
+cable at first, believing that the boy would be
+found during the course of the day. Naturally
+she did not wish to alarm her husband needlessly,
+and the Prefect of Police, it seems, had assured
+her that the child would undoubtedly be recovered
+before night. It wasn't. This morning Mr.
+Stapleton got a long cablegram from his wife,
+telling him of the boy's disappearance. He's half
+crazy over the thing."</p>
+
+<p>"What is he going to do?"</p>
+
+<p>"I don't know. He sent me to see you at once.
+I'm his secretary, you know. When I couldn't
+find you in New York, he told me to come here.
+I arrived in Washington an hour ago, and came
+right out. Mr. Stapleton said if any man on
+earth could find his boy for him, you could."</p>
+
+<p>"I suppose the thing is a matter of blackmail&mdash;ransom&mdash;"</p>
+
+<p>"Very likely. They will probably demand a
+huge sum. No requests have been made, as yet,
+so far as I know. These fellows usually wait a
+week or two, before showing their hand, to give
+the unfortunate parents a chance to worry themselves<span class='pagenum'><a name="Page_15" id="Page_15">[15]</a></span>
+half to death. I suppose they figure that
+then they'll be more likely to come across with
+the money."</p>
+
+<p>"Yes. That's the scheme. A rotten business,
+too. Hanging is too good for such wretches!"</p>
+
+<p>"That's what I say. Of course you can understand
+how Mr. Stapleton feels."</p>
+
+<p>"Of course. He will sail at once, I suppose."</p>
+
+<p>"That's the worst of it. He can't go till Saturday.
+Tomorrow's Thursday&mdash;that's three days
+off. There's a deal on here involving millions&mdash;something
+he's been working to put through for
+months. Of course he doesn't consider anything
+like that, when it comes to his child; but he's
+got to think of his associates&mdash;men who have
+intrusted their money to him. He can't possibly
+sail before Saturday. He wants you to go ahead
+of him. There's a fast boat leaving in the morning.
+You could take that. We can have a conference tonight.
+It will mean mighty quick work,
+though." He glanced at his watch. "After six
+now. There's no train till midnight&mdash;the sleeper.
+But Mr. Stapleton told me to charter a special.
+We can be in New York by one o'clock in the
+morning, if we start right now." He looked at
+Duvall in eager expectancy.</p>
+
+<p>The latter frowned, his gaze wandering off to<span class='pagenum'><a name="Page_16" id="Page_16">[16]</a></span>
+the distant fields, where the newly plowed earth
+reminded him of his plans for the morrow. Yet
+here was a man, a friend, who had helped him
+much, in the earlier days of his career, begging
+him to come to his assistance in a matter almost
+of life or death. It was a difficult decision that
+he was called upon to make. The thought of
+leaving Grace hurt him deeply; yet she would prefer
+to stay behind, in case he should go, to look
+after the affairs of the place. With the assistance
+of the overseer and the hands, he knew that she
+could manage everything during a brief absence
+on his part&mdash;it seemed unlikely that the matter
+would require more than three or four weeks, at
+the outside.</p>
+
+<p>Mr. Hodgman broke in upon his thoughts.
+"You'll go, Mr. Duvall? Mr. Stapleton is depending
+on you. He has the utmost faith in your
+abilities. He knows your familiarity with Paris&mdash;the
+work you have done there, in the past. He
+believes that, by intrusting the matter to a fellow
+countryman, he will get his boy back again. He
+hasn't much faith in foreign detectives. He's set
+his heart on having you start for Paris at once.
+I can't go back and tell him that you have refused."
+Mr. Hodgman spoke in a loud and earnest
+voice, due to his very evident excitement.<span class='pagenum'><a name="Page_17" id="Page_17">[17]</a></span>
+Neither he nor Duvall noticed that Grace had
+approached them, and was standing in the open
+doorway of the house.</p>
+
+<p>Before the detective had an opportunity to
+reply, Grace spoke. "What is it, Richard?" she
+inquired, quietly.</p>
+
+<p>Duvall rose, presented Mr. Hodgman to his
+wife, and bade her sit down. Then, in a few
+words, he acquainted her with the circumstances
+which led to the latter's visit.</p>
+
+<p>"Think of that poor mother, alone there in
+Paris," Hodgman supplemented. "Think of her
+suffering, her anxiety. I realize how much we
+are asking, to take Mr. Duvall away from you,
+especially at this time; but, it is Mr. Stapleton's
+only child&mdash;a boy of six. You can understand
+how he must feel."</p>
+
+<p>Grace nodded. "Yes, I can understand," she
+said, slowly, then turned to her husband.</p>
+
+<p>"What do you think, dear?" he asked her.</p>
+
+<p>"I think, Richard, that you had better go."</p>
+
+<p>Mr. Hodgman sprang to his feet, and, coming
+over to Grace, took her hand. He knew that his
+battle was won. "I thank you, Mrs. Duvall,"
+he said, "on Mr. Stapleton's account, as well as
+on my own. He will appreciate deeply what you
+have done, the sacrifice you are making, and he<span class='pagenum'><a name="Page_18" id="Page_18">[18]</a></span>
+will not forget it." He looked again at his watch
+nervously, the anxiety he felt clearly evident in
+his every movement. "We had best start at once,
+Mr. Duvall."</p>
+
+<p>Duvall rose. "I will join you in a short while,
+Mr. Hodgman. I wish to say a few words to
+my wife." He took Grace's arm and drew her
+within the house, leaving Mr. Hodgman pacing
+nervously up and down the veranda.</p>
+
+<p>The conference between Grace and her husband
+was short. Each realized the distress which
+tore at the other's heart, as well as the dangers
+he would in all probability be called upon to face;
+yet they met the situation calmly. "You will not
+be gone long," she told him. "I can manage very
+well."</p>
+
+<p>"I know you can, dear," he said, pressing her
+to him. "I'm not worried about the place. You
+can run that as well as I can. It's you, I'm
+worried about&mdash;leaving you"&mdash;</p>
+
+<p>"I'll be all right," she assured him, in spite of
+her tears. "I have Aunt Lucy, and old Uncle Abe,
+and Rose, and Jennie. I won't be so <i>very</i> lonely.
+And you will be very careful&mdash;and&mdash;and come
+back soon&mdash;won't you?"</p>
+
+<p>"Of course, dear. Very soon. Now I'd better
+get a few things together."</p>
+
+<p><span class='pagenum'><a name="Page_19" id="Page_19">[19]</a></span>Fifteen minutes later Grace Duvall stood on
+the steps of the veranda, watching the flying automobile
+as it rapidly became a little red blur in
+the distant road. It was nearly dark. The frogs
+in the patch of marsh in the meadow were piping
+dismally. She shivered, and a great sense of
+desolation came over her. She sank into a chair
+and wept, while Don, inserting his long white
+muzzle between her hands, strove to lick away
+her tears.</p>
+
+<p>She heard Aunt Lucy, the old negro cook, singing
+away at her work in the kitchen, accompanied
+by Uncle Abe, who occupied a bench on the back
+porch. Everything seemed strangely peaceful,
+and lonely, too, now that Richard had gone. She
+patted the eager head of the collie. "We'll have
+to make the best of it, Don," she said, and rose
+to enter the house.</p>
+
+<p>Suddenly far down the road she heard the
+chugging of an automobile. They were not frequent
+visitors, upon this country road. Could it
+be Richard, she wondered, returning for something
+he had forgotten?</p>
+
+<p>She stood, straining her eyes into the dusk,
+waiting, while with one hand she restrained the
+eager dog.</p>
+
+<p>Presently she saw that the machine was not a<span class='pagenum'><a name="Page_20" id="Page_20">[20]</a></span>
+red one. It was not Richard. She was about to
+enter the house, when she realized that the rapidly
+moving car had entered the grounds. She
+turned on the lights in the hallway and stood,
+waiting, the dog at her side bristling with anger.</p>
+
+<p>In a moment the automobile had stopped, and
+almost before she realized it, a small, foreign-looking
+man stood on the doorstep before her.
+"Madame Duvall?" he inquired, quickly, in a
+voice which showed plainly his nationality.</p>
+
+<p>"Yes," she replied.</p>
+
+<p>"Your husband! May I see him?"</p>
+
+<p>"He is not at home."</p>
+
+<p>The newcomer seemed greatly disturbed.
+"Then I fear, Madame, that I shall be obliged
+to wait until he returns."</p>
+
+<p>"He will not return. He has gone away for
+sometime."</p>
+
+<p>"Ah! That is indeed a calamity!" The man's
+face showed the keenest disappointment. "May I
+ask where I can find him?"</p>
+
+<p>"It will be quite impossible." Grace had no
+intention of telling her visitor where her husband
+had gone. She knew too well the intricacies of
+his profession, for that. "You cannot find him."
+She made as though to close the door, and thereby
+terminate the interview.</p>
+
+<p><span class='pagenum'><a name="Page_21" id="Page_21">[21]</a></span>The newcomer realized her intention. Slowly
+he raised his hand, in the palm of which showed
+the seal of a ring, turned inward. It was of
+silver, with curious figures worked into it in gold.
+The man glanced from the ring to Grace, eying
+her steadily. "I think, Madame," he said, with
+a meaning smile, "that you can trust me."</p>
+
+<p>Grace recognized the ring at once. It was
+similar to one she herself had worn, while engaged
+in the memorable search for the ivory snuff
+box for Monsieur Lefevre, Prefect of Police
+of Paris. Dear old Lefevre&mdash;the friend of
+Richard's, and of her own! This man who
+stood before her must be a messenger from
+him.</p>
+
+<p>"Come in, please," she said, quietly, and led
+the way to the library.</p>
+
+<p>The man followed her, calling out a few words
+to his chauffeur as he did so. No sooner had
+they reached the great book-lined room, than he
+drew from his pocket a sealed envelope.</p>
+
+<p>"Madame Duvall," he said, earnestly, "Monsieur
+Lefevre has cabled to his representatives in
+Washington a message. That message is contained
+in this envelope. I have instructions to
+deliver it to your husband immediately. In case
+I could not find him, I am to hand it to you.<span class='pagenum'><a name="Page_22" id="Page_22">[22]</a></span>
+Permit, me, Madame." With a bow, he placed
+the message in her hand.</p>
+
+<p>Grace took the envelope, broke the heavy seal
+which it bore, and drawing out a slip of paper,
+hastily read the contents. The message was from
+Monsieur Lefevre. It said:</p>
+
+<div class="blockquote extraspacetop"><p>My dear Duvall:</p>
+
+<p>You promised, on the occasion of our last meeting,
+to come to me should I ever need you. I
+need you badly, my friend. Come at once, both
+you, and your dear wife.</p>
+<p class="right extraspacebot"><span class="smcap">Lefevre.</span></p></div>
+
+<p>Grace looked up at the man before her, the
+letter crumpled in her hand. Here was a message
+the urgency of which could not be denied.
+She knew that, had Richard been at home, he
+would have gone to Paris at once in response to
+it; for it was to Monsieur Lefevre that they in
+reality owed all their happiness. She recalled
+vividly their wedding, with the lovable old
+Frenchman, acting as her father for the occasion,
+giving away the bride. She remembered the farewell
+dinner at the Prefect's house, and the beautiful
+gift he had given her on that occasion. Evidently
+Monsieur Lefevre desired Richard's presence
+very greatly, and her own as well. The<span class='pagenum'><a name="Page_23" id="Page_23">[23]</a></span>
+thought suddenly came to her&mdash;why not go to
+him?</p>
+
+<p>True, Richard had left her in charge of things
+at home; but she knew that, for a reasonable
+time, at least, they would go on smoothly enough
+without her. Hendricks, the overseer, was a
+capable and honest man, devoted to her and to
+her husband.</p>
+
+<p>She could safely leave matters in his charge.
+Then, too, the thought of surprising Richard on
+the steamer sailing the next day appealed to her
+sense of mischief. How astounded he would be,
+to find her strolling along the deck! And how
+delighted, too! She wondered that the thought
+of accompanying him had not occurred to her
+more strongly before. She turned to the man,
+who stood watching her narrowly.</p>
+
+<p>"You know the contents of this message?"</p>
+
+<p>"Yes, Madame," he bowed. "It came to us by
+cable&mdash;in cipher."</p>
+
+<p>"There is a train for New York at midnight,
+and a steamer tomorrow morning."</p>
+
+<p>"Yes, Madame."</p>
+
+<p>"Can you drive me to Washington in your
+car?"</p>
+
+<p>"I shall be delighted, Madame." The fellow's
+eyes sparkled with satisfaction.</p>
+
+<p><span class='pagenum'><a name="Page_24" id="Page_24">[24]</a></span>"Very well. Mr. Duvall is in New York. I
+will take the message to him. Wait here, please,
+until I get some clothes together and give some
+orders to my servants."</p>
+
+<p>In half an hour, the thing was done. Hendricks,
+the overseer, had been given full instructions
+regarding taking charge of the place, with
+provision for his needs in the way of money, etc.,
+and by ten o'clock, at which time the New York
+sleeper was open, Grace was at the station, purchasing
+her ticket.</p>
+
+<p>The obliging Frenchman gave her every assistance,
+and bade her <i>bon voyage</i> smilingly as he
+helped her aboard the train. She retired at once,
+and lay in her berth, reading a magazine, and
+picturing to herself Richard's mingled astonishment
+and joy at their meeting in the morning.
+This time, she was determined that their honeymoon
+should not be interrupted.</p>
+
+<p>After a time, she fell asleep, and dreamed that
+she and Richard were sailing gaily toward Paris,
+in a large red touring car.</p>
+
+<p>In the morning, she ate a hasty breakfast in
+the railway station, and took a taxicab for the
+steamship offices. By great good fortune, she
+was able to secure a cabin. Then she hastily
+visited a banking house where she was well<span class='pagenum'><a name="Page_25" id="Page_25">[25]</a></span>
+known, provided herself with funds, and drove to
+the dock.</p>
+
+<p>It wanted but half an hour till sailing time.
+Grace hastened to her stateroom, and busied herself
+in effacing the stains of her night of travel.
+She was determined to meet Richard looking her
+best.</p>
+
+<p>It was not until the big steamer was passing
+through the Narrows that she came on deck, and
+began looking about for her husband. In all that
+crowd, she knew it would take time to find him.
+After searching for an hour, she felt somewhat
+surprised at not seeing him. After another hour
+had passed, her surprise turned to alarm. A
+hasty visit to the purser, and an examination of
+the sailing list, showed her the astonishing truth.
+Richard was not on board!</p>

+<h2>CHAPTER II</h2>
+
+<p class="cap extraspacetop">RICHARD DUVALL arrived in New York
+at half past one o'clock Thursday morning.
+Hodgman, Mr. Stapleton's secretary,
+had wired ahead the news of their coming,
+and the banker's limousine awaited them at the
+railway station. Fifteen minutes later they were
+ascending the steps of Mr. Stapleton's residence
+on Fifth Avenue.</p>
+
+<p>Duvall had not been to the house before. His
+previous interviews with the banker had taken
+place at the latter's office, in Broad Street. He
+had no time now, however, to observe the luxury
+of his surroundings. Mr. Hodgman hurried him
+at once to the library, and in a few moments Mr.
+Stapleton had joined them.</p>
+
+<p>He greeted Duvall with a nervous handshake,
+and thanked him for his prompt coming. He
+was clearly laboring under an intense mental
+strain.</p>
+
+<p>"Mr. Hodgman has explained my reasons for
+sending for you, Mr. Duvall?" he inquired, sinking
+into a great leather-covered chair.</p>
+
+<p><span class='pagenum'><a name="Page_27" id="Page_27">[27]</a></span>"Yes." Duvall nodded.</p>
+
+<p>"Then you can appreciate my feelings." He
+sat in silence for several moments, looking gloomily
+at the floor.</p>
+
+<p>"Perfectly."</p>
+
+<p>"The devils! I wouldn't care if they were
+to steal my property&mdash;money, securities, anything
+like that. I can fight them&mdash;on that basis.
+But my child! Don't you see why your coming
+was of the utmost importance to me? I don't
+dare move against these rascals openly. If I do,
+they will threaten to retaliate by injuring my
+boy, and I am powerless. Whatever I do, must
+be done secretly. No one must know that you
+are in my employ. No one must know your object
+in going to Paris. You see that?"</p>
+
+<p>"Most certainly. These fellows cannot hold
+you responsible for any moves the police authorities
+of Paris may make; over them you of course
+have no control. But if you make any efforts on
+your own account, any independent efforts, to
+recover your boy, they must by all means be
+made in secret."</p>
+
+<p>"Exactly. You understand, then, what you are
+to do?"</p>
+
+<p>"Yes. But first I must ask you, Mr. Stapleton,
+to give me some account of the affair. Mr.<span class='pagenum'><a name="Page_28" id="Page_28">[28]</a></span>
+Hodgman has told me only that your son has
+been kidnapped. No doubt you have learned by
+this time how the thing was done."</p>
+
+<p>"What I have learned, Mr. Duvall, convinces
+me of the importance of being on the ground at
+once. The affair, as cabled to me by my wife, is
+preposterous&mdash;absurd!" He again gazed at the
+floor in gloomy preoccupation.</p>
+
+<p>"How so?" the detective inquired.</p>
+
+<p>"I will tell you. My boy, who, as you know, is
+six years old, has been in the habit of driving, each
+morning, accompanied by his nurse, from my house
+in the Avenue Kleber, to the Bois de Boulogne.
+On arriving in the Bois, it has been their habit
+to leave the automobile in which they came, and
+spend an hour or more walking and playing on
+the grass. I have insisted on this, because the
+boy needs exercise, and he cannot get it driving
+about in a motor car."</p>
+
+<p>"During this hour what becomes of the car?"
+asked Duvall.</p>
+
+<p>"Our orders have been, of course, for the
+chauffeur to wait, within sight and call. I believe
+he has done so."</p>
+
+<p>"Thank you. Go ahead."</p>
+
+<p>"On Wednesday the nurse took Jack&mdash;the
+boy's name is Jack&mdash;to the Bois as usual. She<span class='pagenum'><a name="Page_29" id="Page_29">[29]</a></span>
+played about with him on the grass for probably
+an hour. Then she sat down to rest. Jack was
+standing near her, playing with a rubber ball.
+She says&mdash;and, gentlemen, my wife cables me that
+she solemnly swears to the truth of her statements&mdash;that
+she turned away for a moment to observe
+passing vehicles in the road&mdash;turned back again
+to the child&mdash;and found that he was gone."</p>
+
+<p>"Gone&mdash;but how?"</p>
+
+<p>"How? That's the question. Here is this
+woman, sitting on the grass, with the child, a
+hundred yards from the road, in the middle of a
+large field of grass&mdash;a lawn. No one is within
+sight. The nearest person, it appears from her
+testimony, is the chauffeur, three hundred feet
+away, in the road. The woman turns her head
+for a moment, looks about&mdash;and the boy is gone.
+That is the story she tells, and which my wife
+has cabled to me. Do you wonder that I call it
+preposterous?"</p>
+
+<p>"Hardly," remarked Duvall, with a grim smile.
+"The boy could not have vanished into thin air.
+The woman must be lying."</p>
+
+<p>"That, Mr. Duvall, is what I cannot understand.
+I cannot believe that the woman is lying.
+My wife cannot believe it. She has been in our
+employ ever since the boy was born, and is devoted<span class='pagenum'><a name="Page_30" id="Page_30">[30]</a></span>
+to him. Mrs. Stapleton cables that she is
+completely prostrated."</p>
+
+<p>"But, Mr. Stapleton, you can hardly believe
+such a story! How could the child have been
+stolen, if her story is true? It is, as you say, preposterous."</p>
+
+<p>"I do not say that the story is true, Mr. Duvall.
+I say that I do not think that Mary is
+lying. She is telling what she believes to be the
+truth. She turned her head for a moment&mdash;the
+boy was gone. That is what she says, and I believe
+her. The question is&mdash;how is it possible?"</p>
+
+<p>"It isn't," Hodgman grunted.</p>
+
+<p>"Everything is possible, Hodgman," said the
+banker, reprovingly. "The best proof of that,
+in this case, is that it has happened. What means
+were used, I cannot imagine; but the apparently
+impossible <i>has</i> happened. The boy is gone!"</p>
+
+<p>"Is the nurse a young woman?" the detective
+inquired.</p>
+
+<p>"About thirty, I should say."</p>
+
+<p>"An American?"</p>
+
+<p>"Yes. Of Irish parentage. Her name is Lanahan&mdash;Mary
+Lanahan."</p>
+
+<p>"A New Yorker?"</p>
+
+<p>"She comes from Paterson, New Jersey. Her
+people live there."</p>
+
+<p><span class='pagenum'><a name="Page_31" id="Page_31">[31]</a></span>"Are there any other details&mdash;any other points
+of interest?"</p>
+
+<p>"None, so far as I know. What I have told
+you, is what has been cabled to me by Mrs. Stapleton.
+She is naturally in a more or less hysterical
+condition. Nothing can be accomplished here.
+I want you to leave by today's steamer. I myself,
+I regret to say, cannot go until Saturday." He
+passed his hand nervously across his forehead.
+"Only matters of the most vital importance could
+keep me here at such a time, Mr. Duvall; but,
+unfortunately, such matters confront me now."</p>
+
+<p>"Have you any reason to believe, Mr. Stapleton,"
+Duvall inquired, "that the kidnapping is the
+act of persons from this side of the water? Have
+any such attempts been made in the past?"</p>
+
+<p>Mr. Stapleton remained silent for sometime,
+buried in thought. Presently he spoke. "I am
+a rich man, Mr. Duvall&mdash;a very rich man. Men
+in my position are constantly in receipt of letters
+of a threatening nature. I have received many
+such letters, in the past."</p>
+
+<p>"Was the matter of the child mentioned in
+any of them? Were threats made involving
+him?"</p>
+
+<p>"There was one such letter."</p>
+
+<p>"When did you receive it?"</p>
+
+<p><span class='pagenum'><a name="Page_32" id="Page_32">[32]</a></span>"Last fall&mdash;perhaps six months ago."</p>
+
+<p>"Have you the letter now?"</p>
+
+<p>"Yes."</p>
+
+<p>"May I see it?"</p>
+
+<p>The banker rose, went to a heavy rosewood
+desk at one side of the room, drew open one of
+its drawers, and removed a steel despatch box.
+He opened it with a slender key and took out a
+package of letters. From these, after some hesitation,
+he selected one and silently handed it to
+Duvall.</p>
+
+<p>The detective examined the letter carefully.
+It was enclosed in a cheap white envelope, such
+as are sold at all post offices, having the stamp
+printed on it. The letter itself was roughly
+printed in ink on a sheet of ruled paper evidently
+torn from an ordinary five-cent pad. It said:</p>
+
+<p class="blockquote extraspacetop extraspacebot">"We demand fifty thousand dollars, to be
+placed in thousand-dollar bills inside a cigar box
+and expressed to John Smith, c/o Express Company,
+Paterson, N. J., next Monday afternoon.
+The man who will call for the package on Tuesday
+will know nothing about the matter, and if
+you arrest him, you will find out nothing. Keep
+this to yourself and do as we say, if you value
+the safety of your child."</p><p><span class='pagenum'><a name="Page_33" id="Page_33">[33]</a></span></p>
+
+<p>There was no signature to the letter. Duvall
+read it through with great care, then turned to
+Mr. Stapleton.</p>
+
+<p>"You have observed, I suppose, that the place
+to which the money was to be sent, Paterson, New
+Jersey, is the home of your child's nurse, Mary
+Lanahan."</p>
+
+<p>Mr. Stapleton started. "I confess," he said
+"that, in the agitated state of mind into which this
+affair has thrown me, I had completely overlooked
+the coincidence. What do you infer from
+it?"</p>
+
+<p>"Only this, Mr. Stapleton, that Mary Lanahan
+may know more about this matter than she is
+willing to let on. I must keep this letter for the
+present."</p>
+
+<p>"Very well." The banker nodded. "It may
+prove a valuable clue."</p>
+
+<p>"Possibly. And further, Mr. Stapleton, I shall
+not sail by today's steamer."</p>
+
+<p>"But&mdash;why not?" Stapleton sat up in his chair
+in surprise. "You will lose two days."</p>
+
+<p>"I do not think they will be lost. I must make
+some investigations in Paterson, before I leave
+here. Please give me, if you can, the address of
+Mary Lanahan's parents."</p>
+
+<p>Mr. Stapleton frowned. "I am not sure that<span class='pagenum'><a name="Page_34" id="Page_34">[34]</a></span>
+I can do so, Mr. Duvall. My wife has charge
+of these matters. But I recollect having heard
+that her father, Patrick Lanahan, is a florist in
+a small way, and no doubt you can readily locate
+him. But I fear you will be losing valuable
+time."</p>
+
+<p>Duvall rose. "I feel, as you do, Mr. Stapleton,
+that I should be in Paris at the earliest possible
+moment; but I think you will agree with me
+that some investigations on this side before I go
+are absolutely necessary, and may prove of inestimable
+value afterwards."</p>
+
+<p>Mr. Stapleton was silent for several minutes.
+Presently he raised his head. "Under the circumstances,
+Mr. Duvall, I am forced to admit
+the truth of what you say. Conduct your investigations
+as quickly as possible, however; for we
+must positively sail by Saturday's boat."</p>
+
+<p>"I shall be ready then." Duvall took up his
+hat. "Now I think I had better get a few hours'
+sleep, and in the morning I will make an early
+start for Paterson." He bowed to the banker
+and Mr. Hodgman. "Good night, gentlemen. I
+shall see you both on Saturday morning. The
+steamer sails shortly after noon, I believe. Suppose
+I come here at ten o'clock, and let you know
+what I have learned?"</p>
+
+<p><span class='pagenum'><a name="Page_35" id="Page_35">[35]</a></span>Mr. Stapleton rose. "If I receive any further
+news of importance from Paris, Mr. Duvall, I
+will advise you at your hotel. Where are you
+stopping?"</p>
+
+<p>Duvall gave the name of a Times Square hotel
+at which he usually stopped, and with a quick
+"good night" left the house.</p>
+
+<p>It was shortly after nine o'clock the next morning
+when he descended from the train at Paterson,
+and going to a nearby drug store, consulted the
+directory for the address of Patrick Lanahan.
+He found it without difficulty, and, by means of
+an electric car, was soon before the florist's door.</p>
+
+<p>The place was situated on the outskirts of the
+town, and consisted of a small, rather mean-looking
+cottage, from which spread out on each side,
+like the two wings of an a&euml;roplane, the long glass
+greenhouses.</p>
+
+<p>A little gate opened to a short brick path, leading
+to the front door of the house.</p>
+
+<p>Duvall went up the path and rang the door
+bell. A wholesome-looking Irish woman, of perhaps
+fifty, opened the door, and, in response to
+his questions, told him that her husband, Patrick,
+was out in the garden at the rear of the house,
+busy with his plants.</p>
+
+<p>She directed the detective along a narrow areaway<span class='pagenum'><a name="Page_36" id="Page_36">[36]</a></span>
+at the side of the house, and in a moment reappeared
+at the back door.</p>
+
+<p>"Pat," she called. "Oh, Pat! Here's a gentleman
+to see you."</p>
+
+<p>A short, heavy-set man, with gray hair and
+mustache and a ruddy and weatherbeaten face,
+arose from among a litter of flower pots and
+bulbs.</p>
+
+<p>"What can I do for you, sir?" he asked, coming
+forward and wiping his hands upon his overalls.</p>
+
+<p>The detective studied the man before him intently.
+The honest and clear-looking eyes told
+him nothing that was not favorable.</p>
+
+<p>"I came to ask you a few questions, Mr. Lanahan."</p>
+
+<p>"Questions, is it? About what?" The blue
+eyes showed a sudden flare of suspicion.</p>
+
+<p>"About yourself, and your family."</p>
+
+<p>"Who may you be, then? Is it the tax man?"</p>
+
+<p>Duvall smiled. "Not the tax man," he said.
+"I represent a firm of lawyers in Washington. My
+name is Johnson."</p>
+
+<p>Lanahan, still suspicious, pointed to a couple
+of kitchen chairs that stood on the brick-paved
+yard beneath a trellis covered with hop vines.
+"Sit down, sir. I'll have a smoke, if you don't<span class='pagenum'><a name="Page_37" id="Page_37">[37]</a></span>
+mind." He began to fill his short clay pipe.
+"What would lawyers in Washington be wantin'
+with me?"</p>
+
+<p>"That is what I wish to find out, Mr. Lanahan.
+We&mdash;my firm&mdash;have been advised that a
+certain Michael Lanahan, of Dublin, recently
+died, leaving a large estate. We are trying to
+find his heirs. Tell me something about yourself
+and your family."</p>
+
+<p>The look of suspicion and reserve which the
+old man had up to this time shown faded from
+his face, and was replaced by a smile of incredulity.
+"Money, is it?" he laughed. "Mary&mdash;that's
+my wife&mdash;has been seein' bubbles in her tay for
+the week past. What is it you would know?"</p>
+
+<p>"Are you from Dublin?"</p>
+
+<p>"Me father was. I was born right here in
+Jersey, meself."</p>
+
+<p>"What was his name?"</p>
+
+<p>"Patrick, the same as me own. But he had a
+brother, Mike."</p>
+
+<p>"Ah. It may be the same." Duvall pretended
+a sudden interest. "His business?"</p>
+
+<p>"Mike's? Faith&mdash;I never heard he had any,
+lest it was drinkin' all the good liquor he could
+lay his hands on."</p>
+
+<p>Duvall pretended to make a series of entries<span class='pagenum'><a name="Page_38" id="Page_38">[38]</a></span>
+in his notebook. "Now about yourself, Mr.
+Lanahan. Have you any children? Of course,
+should there be any money coming to you, they
+would share in it."</p>
+
+<p>"Children, is it? I have two."</p>
+
+<p>"Boys?"</p>
+
+<p>"One is a boy&mdash;a man be now, I should say.
+He's in the city&mdash;workin'. His name is Barney."</p>
+
+<p>"What does he do?"</p>
+
+<p>Lanahan looked up with a quick frown. "The
+last I heard tell, he was tendin' bar, Mr. Johnson&mdash;over
+at Callahan's saloon, on the Bowery. He's
+wild&mdash;wild&mdash;like me uncle Mike, I should say."</p>
+
+<p>"And the other?"</p>
+
+<p>The old man's face took on a contented look.
+"The other is me daughter Mary, bless her. She's
+nurse in the family of old man Stapleton, the millionaire."</p>
+
+<p>Duvall closed his book. "I see," he remarked,
+pleasantly. "She's not married, I suppose?"</p>
+
+<p>"Mary? Divil a bit! For a time, she was
+sweet on a French chuffer that worked for Mr.
+Stapleton; but the fellow's gone, now, and she's
+clane forgot him. That was near a year ago."</p>
+
+<p>"Ah, yes. Do you happen to remember his
+name?"</p>
+
+<p>"Alphonse, it was&mdash;Alphonse Valentin, or some<span class='pagenum'><a name="Page_39" id="Page_39">[39]</a></span>
+such joke of a name. A comic valentine he was,
+too, with his dinky little mustache and his cigarettes."
+He laughed loudly. "Imagine my Mary,
+married to a gink like that!"</p>
+
+<p>Duvall replaced his notebook in his pocket
+and rose. "I'm mightily obliged to you, Mr.
+Lanahan. We will advise you at once, if our investigations
+show that you are related to the
+Michael Lanahan whose fortune is in our hands.
+I'm obliged to you for your courtesy."</p>
+
+<p>The florist nodded. "You're welcome, sir. I
+guess them Lanahan's must be a different breed.
+I never heard tell of any of my people makin'
+any fortune. Good day, sir." He turned to his
+work, chuckling.</p>
+
+<p>Duvall rode back to the station, and took the
+first train for New York. It was clear that Mary
+Lanahan's parents had nothing in common with
+blackmailers and kidnappers. Their honesty was
+as evident as the blueness of their eyes, or the
+redness of their hair. But the information about
+Alphonse Valentin, the chauffeur, and Barney,
+Mr. Lanahan's son, seemed more promising.</p>
+
+<p>It was close to one o'clock when Duvall arrived
+at Callahan's saloon, on the Bowery, near Canal
+Street. Here a disappointment awaited him.
+Barney Lanahan had thrown up his job and left<span class='pagenum'><a name="Page_40" id="Page_40">[40]</a></span>
+two months before. Callahan had no idea where
+he had gone. He had not been about the place
+since. A negro porter volunteered the information
+that he had seen the man entering the Broadway
+saloon of an ex-prizefighter some weeks before;
+but, beyond that, Duvall could learn nothing.</p>
+
+<p>After a hasty luncheon he went to his office
+on Union Square, where his unexpected appearance
+caused his assistants unlimited surprise. He
+directed them to locate Barney Lanahan at the
+earliest possible moment. He then called up Mr.
+Stapleton's secretary, Mr. Hodgman, and inquired
+about the chauffeur.</p>
+
+<p>Mr. Hodgman informed him that the banker
+had employed Valentin in Paris some eighteen
+months previous, and had brought him to this
+country, where he had remained in his employ
+for about six months. He had been discharged,
+through some dishonesty in the matter of purchasing
+supplies, and nothing further had been
+seen or heard of him.</p>
+
+<p>Duvall, on receiving this information, proceeded
+at once to the office of the French line,
+and asked permission to inspect their passenger
+lists for the past year. He concluded that if
+Valentin had anything to do with the kidnapping
+of Mr. Stapleton's boy, he was, in all probability,<span class='pagenum'><a name="Page_41" id="Page_41">[41]</a></span>
+in Paris, and, if so, would almost certainly have
+crossed by this line. He was therefore not at all
+surprised to find the name of Alphonse Valentin
+among those sailing during the preceding March.</p>
+
+<p>There was little more that he could accomplish,
+now, beyond writing a long letter to Grace, whom
+he naturally supposed to be patiently awaiting his
+return in the country. He had a short interview
+with Mr. Hodgman in the evening, and was lucky
+enough to secure a photograph of Alphonse Valentin,
+the chauffeur, taken at the steering wheel
+of his machine. The car had, it seemed, been
+photographed, along with a party of guests, by
+a friend of Mr. Stapleton's with a leaning toward
+amateur photography. Duvall placed the photograph
+among his belongings with a smile of satisfaction.
+He felt that his delay had been by no
+means unprofitable.</p>
+
+<p>One other step he took, before leaving. Accompanied
+by Mr. Hodgman, he made a careful
+inspection of the room which had been occupied
+by the nurse, Mary Lanahan, at the Stapleton
+house. The results were distressingly meager.
+All the woman's belongings she had evidently
+taken with her, on going abroad. There appeared
+to be nothing which would afford the slightest
+clue to her character or habits.</p>
+
+<p><span class='pagenum'><a name="Page_42" id="Page_42">[42]</a></span>Mr. Hodgman turned to the door with an impatient
+frown. "Nothing here," he growled, and
+was about to leave the room.</p>
+
+<p>"Nothing much," said Duvall, glancing carelessly
+at the wooden edge of the bureau. "This
+woman, Mary Lanahan, is evidently an up-to-date
+sort of person."</p>
+
+<p>Hodgman paused. "Why do you say that?"
+he asked.</p>
+
+<p>"Smokes cigarettes, I see."</p>
+
+<p>"That so. How do you know?"</p>
+
+<p>Duvall smiled. "Too simple even to mention,
+Mr. Hodgman. See those burns on the varnish?"
+He pointed to a number of spots along the edge
+of the dresser. "Always find them somewhere
+about, where there's a cigarette smoker." He
+gazed out of the window for a moment. "Rooms
+tell a great deal about the personality of the people
+who have occupied them. For instance, I've
+never seen this Lanahan girl, but I know that she's
+not over five feet four, that she has light hair,
+that she reads in bed, that she writes with a stub
+pen, and that she's a Roman Catholic. Furthermore,
+she is left handed, inclined to be vain,
+wears her hair in waves, or curls, in front, is
+fond of the theater, and has a long narrow scar
+on the palm of her left hand."</p>
+
+<p><span class='pagenum'><a name="Page_43" id="Page_43">[43]</a></span>He chuckled quietly, as he saw Mr. Hodgman's
+look of amazement. "All very simple&mdash;quite
+elementary, in fact. I won't even bother to
+tell you how I know&mdash;just little things here and
+there about the room. Here's one of them," he
+said, as he picked up a rusty pen point from the
+desk. "That shows she uses a stub, of course;
+but the way the point is worn also proves that
+she's left handed. And here's another." He
+pointed to the electric bulb which hung over the
+head of the bed. "Nobody would use that light,
+except to read by in bed. The others in the room
+are more than sufficient for purposes of illumination.
+Yet the lamp has been used continuously, as
+its condition shows. See how blackened the glass
+is&mdash;and notice also how the white enamel of the
+back of the bed is worn off, just under the lamp.
+That's from propping a pillow against it, night
+after night." He turned toward the door. "Of
+course, those things aren't of any value, probably,
+in this case; but I can't help noticing them. Force
+of habit, I suppose."</p>
+
+<p>When Duvall arrived at the Stapleton house
+on Saturday morning, he found the banker somewhat
+disturbed by a cablegram he had just received.
+"Mary claims attempts made to poison
+her. Will recover. Come at once," it read.</p>
+
+<p><span class='pagenum'><a name="Page_44" id="Page_44">[44]</a></span>The detective appeared to be somewhat astonished,
+on reading the cablegram. "Looks as
+though somebody was afraid she might be going
+to talk," he remarked. "The sooner we arrive
+in Paris, now, the better."</p>
+

+<h2>CHAPTER III</h2>
+
+<p class="cap extraspacetop">GRACE DUVALL'S first inclination, on
+finding herself en route for Europe, without
+her husband, was to send him a wireless,
+advising him of her movements. Then she
+decided, for several reasons, not to do so. Chief
+among these was the fear that such a startling
+piece of news would be likely to cause him a
+great deal of unnecessary anxiety. She knew that
+she could never hope to explain matters, within
+the limits of a marconigram. And then, too, it
+was highly inadvisable, she knew, to mention in
+a wireless message the real reason which had
+caused her to leave home.</p>
+
+<p>So she decided to make the best of the matter,
+realizing that within a few days, she would see
+Richard in Paris, and explain everything to his
+satisfaction.</p>
+
+<p>Immediately on reaching Paris, she drove to
+the office of the Prefect of Police, and sent in her
+card to Monsieur Lefevre. She thought it possible
+that he would expect her, as his agent in<span class='pagenum'><a name="Page_46" id="Page_46">[46]</a></span>
+Washington would no doubt have communicated
+with him. Nor was she mistaken.</p>
+
+<p>He rushed into the anteroom as soon as he
+received her card, and embraced her with true
+Gallic fervor, kissing her on both cheeks until
+she blushed. Then he drew her into his private
+office.</p>
+
+<p>"Where is your husband?" he asked, eagerly,
+as soon as Grace was seated.</p>
+
+<p>"I&mdash;I do not know. Probably on his way to
+Paris."</p>
+
+<p>"But&mdash;my dear child! Did he not then come
+with you?"</p>
+
+<p>"No. He&mdash;he had other business."</p>
+
+<p>"Other business! But I understood that he had
+temporarily retired." The Prefect seemed greatly
+astonished.</p>
+
+<p>"So he had; but an old friend, Mr. Stapleton"&mdash;</p>
+
+<p>Lefevre did not allow her to finish. "Stapleton!"
+he fairly shouted. "He is employed by
+him? Mon Dieu!"</p>
+
+<p>"Why not?" asked Grace in surprise.</p>
+
+<p>"But&mdash;it was for that very case that I desired
+his assistance. And by this Stapleton, who cables
+that the whole police force of Paris are a lot of
+jumping jacks! Sacr&eacute;! It is insufferable!"</p>
+
+<p><span class='pagenum'><a name="Page_47" id="Page_47">[47]</a></span>"You wanted my husband for the same case?"</p>
+
+<p>"Assuredly! What else? The child of this
+pig of a millionaire is stolen&mdash;what you call&mdash;kidnapped!
+We have been unable to find the slightest
+clue. I am in despair. My men assure me
+that it is the work of an American gang. I conceive
+the hope that Monsieur Duvall may know
+these men&mdash;that he may be in possession of information
+that will lead to their capture. This
+rich American, he has spoken with contempt of
+the Paris police. The efficiency of my office is
+questioned. My honor is at stake. I send for
+my friend Duvall, to assist me, and&mdash;sacr&eacute;!&mdash;I
+find him already working for this man who has
+insulted me. It is monstrous!"</p>
+
+<p>Grace could scarcely repress a smile. How
+excessively French the Prefect was, after all.
+"My husband did not know, when he agreed to
+take the case for Mr. Stapleton, that you wanted
+him. He does not know it now. He has not yet
+received your message."</p>
+
+<p>"Then he does not know that you are in
+Paris?"</p>
+
+<p>"No. I thought he would be crossing on the
+same boat. When I found that he wasn't, my
+first thought was to send him a wireless. Then
+I realized that I couldn't do so, without saying<span class='pagenum'><a name="Page_48" id="Page_48">[48]</a></span>
+something about the business that had called me
+to Paris&mdash;without, in fact, mentioning you. I
+feared to do this&mdash;for there are so many people
+nowadays tapping the wireless. I thought it better
+to keep the matter a secret."</p>
+
+<p>"And you did quite right. I wanted your husband
+to take up this case, quite independently,
+and without it being known to anyone that he
+was in my employ." He paused for a moment
+in deep thought. "No doubt his employment by
+Mr. Stapleton is to be kept equally secret."</p>
+
+<p>"I suppose so. He asked me not to say anything
+about it. I had to tell you, to explain matters."</p>
+
+<p>"And he doesn't know that you are in Paris?"
+The Prefect gave a sudden laugh. "<i>Ma foi!</i>&mdash;what
+a joke!"</p>
+
+<p>"A joke?"</p>
+
+<p>"Assuredly! Don't you see? I am going to
+ask <i>you</i> to take up this case, yourself. I must
+use every means to recover the child of this Stapleton,
+before others do so for him. My professional
+pride will not permit me to be beaten. If
+I can't have your husband, at least I shall have
+you."</p>
+
+<p>"But&mdash;I shall be working in opposition to him."</p>
+
+<p>"Not in opposition. You will both have the<span class='pagenum'><a name="Page_49" id="Page_49">[49]</a></span>
+same object in view&mdash;the recovery of Mr. Stapleton's
+boy. Whichever of you does so first, the
+result will be the same&mdash;the boy will be restored
+to his parents. But I want you, my child, to be
+the one to do this."</p>
+
+<p>"But, Monsieur Lefevre, I could not hope to
+accomplish anything&mdash;where trained men have
+failed."</p>
+
+<p>"Who knows? I remember well the assistance
+you gave us, in the matter of the ivory snuff box.
+Without your help, we should never have recovered
+it. I have faith in a woman's intuition. You
+will find this child for me, and give your husband
+the surprise of his life."</p>
+
+<p>"But," said Grace, smiling mischievously at the
+prospect which opened before her, "suppose he
+should see me?"</p>
+
+<p>"You must disguise yourself somewhat. Change
+the color of your hair; it is easily done&mdash;here in
+Paris." The Prefect laughed. "A slight alteration
+in appearance only will be necessary. And
+do not recognize your husband, should you meet
+him face to face. That is most important."</p>
+
+<p>"Why?"</p>
+
+<p>"Because, should he become convinced that it
+is really you, I fear he would insist upon your
+dropping the case entirely, and that would not<span class='pagenum'><a name="Page_50" id="Page_50">[50]</a></span>
+suit my plans at all. Come, my child." The Prefect's
+eyes twinkled with amusement. "Do this
+thing for me. It will be a little joke, between us.
+The honeymoon detectives, I called you, once.
+What an amusing thing, that now you should be
+working in competition with each other, on the
+same case!" He began to laugh heartily.</p>
+
+<p>"Well," said Grace, her sense of mischief getting
+the better of her, "now that I'm here, I suppose
+I might as well keep busy. Richard won't
+be here for two days, and I may find out something
+in that time."</p>
+
+<p>"Excellent!" The Prefect clapped his hand
+smartly upon his knee. "You have two days'
+start. In two days, much may be accomplished.
+Come, let us go over the case in detail."</p>
+
+<p>An hour later, Grace left the Prefect's office
+in a taxicab, having arranged to have her baggage
+sent to Monsieur Lefevre's house, where she was
+to stay while in Paris. Her previous acquaintance
+with Madame Lefevre made this an ideal arrangement.
+She was to pose as a friend, in Paris
+on a visit.</p>
+
+<p>She ordered the driver of the taxicab to take
+her to Mr. Stapleton's house in the Avenue
+Kleber.</p>
+
+<p>She found Mrs. Stapleton to be a very pretty<span class='pagenum'><a name="Page_51" id="Page_51">[51]</a></span>
+and stylish woman of thirty; whose beauty, however,
+was sadly marred by the intense suffering
+through which she was passing. The poor creature
+had scarcely slept for over a week, and her
+distress was pitiable.</p>
+
+<p>She answered Grace's questions as well as she
+could, under the circumstances. There was, after
+all, little to say. The nurse, it appeared, stuck to
+her story&mdash;that the boy had vanished, in the
+twinkling of an eye, while her back had been
+turned for but a few moments. Mrs. Stapleton
+could offer no explanation&mdash;attempted none.</p>
+
+<p>"It is all so mysterious&mdash;so terrible!" she cried.
+"Poor Mary&mdash;she is too ill to see you, I fear,
+or I would have her tell you the story herself."</p>
+
+<p>"Too ill?" inquired Grace, who had come more
+to question the maid, than Mrs. Stapleton.
+"What is the matter with her?"</p>
+
+<p>"They tried to poison her&mdash;last Friday."</p>
+
+<p>"They? Who?"</p>
+
+<p>"I do not know. She went out for a walk.
+The poor woman was half dead, from nervous
+exhaustion and loss of sleep. She tells me that
+she stopped to get a cup of chocolate at a caf&eacute;
+in the Rue St. Honor&eacute;. After that she came
+back to the Champs &Eacute;lys&eacute;es, and sat upon a bench.
+She began suddenly to feel deathly ill, and, calling<span class='pagenum'><a name="Page_52" id="Page_52">[52]</a></span>
+a cab, was driven home. When she arrived
+here, she was unconscious, and had to be carried
+to her room by the servants. She has been
+in bed ever since. I am glad to say, however,
+that she is better, and I think she could see you,
+by morning."</p>
+
+<p>Grace left the Stapleton house, feeling somewhat
+baffled. The more she heard of this curious
+affair, the more inexplicable it seemed. She had
+hoped to visit the scene of the kidnapping, in
+company with the nurse, and examine the spot
+with her own eyes. This she now realized she
+could not do until the following day. She was
+walking in the direction of the Arc de Triomphe,
+revolving the affair in her mind, when a young
+man, evidently a Frenchman, of good appearance
+and not unpleasant face, came up beside her,
+bowed politely, and in excellent English asked her
+regarding Mary Lanahan.</p>
+
+<p>"Miss Lanahan&mdash;is she better?" he inquired.</p>
+
+<p>"Who are you, monsieur?" asked Grace, suppressing
+her inclination to resent the man's action,
+in her hope that she might learn something from
+him of value. His question showed Grace at
+once that he was acquainted with at least one
+member of the Stapleton household.</p>
+
+<p>"I am a friend of Miss Lanahan's," the man<span class='pagenum'><a name="Page_53" id="Page_53">[53]</a></span>
+replied. "I hear that she is ill. I saw you enter
+and leave the house, and I ventured to ask you
+if she is better."</p>
+
+<p>"I was told that she is. I did not see her."</p>
+
+<p>A peculiar expression crossed the young man's
+face; but Grace could not determine, so fleeting
+was it, whether it indicated pleasure or disappointment.</p>
+
+<p>They walked along in silence for a few moments,
+and had almost reached the arch, when
+a ragged little urchin, a veritable Paris gamin,
+came up to Grace's companion and thrust a crumpled
+bit of paper into his hand, then darted off,
+whistling shrilly.</p>
+
+<p>The man looked after him a moment, then
+examined the note. Whatever its contents, they
+made a startling impression upon him. He
+looked about, an expression of fear upon his
+face, turned to Grace with a hurried bow, and a
+quick good evening, and at once walked off in the
+opposite direction at full speed, at the same time
+fumbling in the breast pocket of his coat, as
+though searching for something in it. In his efforts,
+he dropped several papers to the street.
+Grace watched him as he picked them hurriedly
+up and moved off into the gathering darkness.</p>
+
+<p>She fancied that one of the bits of paper had<span class='pagenum'><a name="Page_54" id="Page_54">[54]</a></span>
+escaped his notice, and, on going back to the spot,
+found that she was correct. A small visiting card
+lay upon the sidewalk. She picked it up, and read
+the name as she walked away. It was Alphonse
+Valentin, Boulevard St. Michel.</p>
+
+<p>Grace slipped the card into her pocketbook.
+The man's name meant nothing to her&mdash;she
+fancied that he was some friend of Miss Lanahan's,
+concerned about her condition. Yet why
+did he not inquire for her at the house, in the
+ordinary way? And why should the note, handed
+to him by the street urchin, have caused him such
+evident alarm?</p>
+
+<p>She glanced at her watch, and saw that it was
+close to seven o'clock. She had intended to return
+to Monsieur Lefevre's for dinner; but a
+sudden determination to find out more about this
+man Valentin caused her to proceed at once to a
+hotel near the Louvre, where she ate her dinner
+alone.</p>
+
+<p>An hour later she descended from a cab at the
+number on the Boulevard St. Michel, which was
+inscribed upon Alphonse Valentin's card.</p>
+
+<p>The place was a dingy old building, the main
+floor of which was occupied by a dealer in cheese.
+A narrow doorway at one side gave access to the
+upper floors. Grace rang the bell, and waited in<span class='pagenum'><a name="Page_55" id="Page_55">[55]</a></span>
+some trepidation. This going about Paris at
+night was rather an unusual experience. She
+thought of the simple joys of her life at home,
+and for a moment regretted that she had not
+stayed there. The opening of the door interrupted
+her thoughts.</p>
+
+<p>The woman who stood in the hallway regarded
+her without particular interest, and inquired her
+business. "I wish to see Monsieur Valentin," said
+Grace.</p>
+
+<p>"He is not in."</p>
+
+<p>"Then I will wait. I must see him. He expects
+me."</p>
+
+<p>The woman shrugged her shoulders. "As you
+wish, mademoiselle. Come this way." She led
+Grace up a flight of stairs, and indicated a door
+at the rear of the upper hall. "That is Monsieur
+Valentin's room." Then she turned away, apparently
+quite indifferent as to whether Grace entered
+or not.</p>
+
+<p>The latter placed her hand on the knob of the
+door, and slowly pushed it open. The room was
+dark; but the light from the rear windows rendered
+the objects within it faintly visible. Upon
+the table stood a lamp. With some difficulty the
+girl succeeded in finding a match, and lit it.</p>
+
+<p>The light of the lamp disclosed a rather large<span class='pagenum'><a name="Page_56" id="Page_56">[56]</a></span>
+room, with a small alcove in the rear, containing
+a bed. The alcove was curtained off from the
+main room. Grace, however, did not spend much
+time in examining her surroundings. A photograph
+on the table at once attracted her attention&mdash;not
+because it represented anyone she knew,
+but because, across the bottom of it, was inscribed,
+in a feminine hand, "Mary Lanahan."</p>
+
+<p>She had just completed her examination of the
+photograph, when two other objects attracted her
+attention. One was a crumpled bit of paper,
+upon which a few words were scrawled in
+lead-pencil. They were, "I am suspicious of
+Fran&ccedil;ois. Watch him." The note was unsigned.</p>
+
+<p>The third object upon the table which caught
+Grace's attention was a box of cigarettes, open,
+and nearly full. They were small gold-tipped
+affairs, of the kind generally used by women, and
+it was this peculiarity that at first attracted her
+attention. She thought it strange, that a man
+should use such cigarettes. She looked at the
+box, and observed that they were of American
+make.</p>
+
+<div class="figcenter extraspacetop" >
+<img src="images/illus02a.jpg" width="384" height="623" alt="Once inside he made without hesitation for the table, picked
+up the box of cigarettes and thrust it into his pocket." title="" /></div>
+<p class="center caption blockquote">Once inside he made without hesitation for the table, picked
+up the box of cigarettes and thrust it into his pocket.</p>
+
+<p class="extraspacetop">Idly she took up one of the cigarettes, and held
+it in her fingers. She read the name of the brand,
+printed upon the paper wrapper, and was about
+<span class='pagenum'><a name="Page_57" id="Page_57">[57]</a></span>to drop it back into the box, when she heard a
+curious rasping noise outside one of the rear windows.
+It sounded as though someone were climbing
+the wall of the house. Instinctively she
+shrank back and concealed herself behind one
+of the curtains which hung before the alcove
+door.</p>
+
+<p>The rasping and scraping continued for some
+little time, and presently Grace, peering through
+the space between the curtains, saw a face appear
+at one of the windows. It was a determined face,
+heavily bearded, dark, evil looking. Its gleaming
+eyes swept the room with cautious care, then, evidently
+satisfied that it was unoccupied, their
+owner began noiselessly to raise the sash of the
+window.</p>
+
+<p>It was slow work. Several minutes passed before
+the man succeeded in raising the sash sufficiently
+to permit him to crawl into the room.
+Once inside, he made without hesitation for the
+table, glanced over its contents, picked up the box
+of cigarettes and thrust it into his pocket, and
+then, without paying the least attention to anything
+else, walked quickly to the door of the room
+and passed out into the hall.</p>
+
+<p>The girl waited for a moment, then stepped
+into the light. As she did so, she realized that<span class='pagenum'><a name="Page_58" id="Page_58">[58]</a></span>
+she held in her hand one of the gold-tipped cigarettes
+she had taken from the box. She quickly
+thrust it into her pocketbook, and, with sudden
+decision, left the room and descended the stairs.
+She had an instinctive feeling that the man who
+had stolen the cigarettes was in some way connected
+with the kidnapping of the Stapleton
+child. She determined to follow him, leaving
+the interview with Alphonse Valentin to another
+time.</p>
+
+<p>She left the house, and saw the man going
+down the Boulevard some fifty feet in advance of
+her. She walked along after him, pretending to
+be totally uninterested in her surroundings, while
+at the same time keeping a sharp watch upon
+him.</p>
+
+<p>He seemed in somewhat of a hurry, and walked
+briskly along, looking neither to left nor to right.
+Grace kept as close to him as she dared, without
+running the risk of detection. The walk was a
+long one. When half an hour had passed, the
+girl saw that they were entering the Champs
+&Eacute;lys&eacute;es. The Seine they had long since crossed
+by the Pont Neuf. Up the brilliantly lighted avenue
+they went, toward Arc de Triomphe. At the
+corner of the Avenue Kleber, the man turned to
+the left. Grace followed, wondering where the<span class='pagenum'><a name="Page_59" id="Page_59">[59]</a></span>
+chase would lead next. To her astonishment, the
+man disappeared suddenly through a gate which
+formed the servants' entrance of one of the stately
+houses which fronted on the avenue. She looked
+up. It was the house of Mr. Stapleton!</p>
+

+<p><span class='pagenum'><a name="Page_60" id="Page_60">[60]</a></span></p>
+<h2>CHAPTER IV</h2>
+
+<p class="cap extraspacetop">ON the day following that upon which she
+arrived in Paris, Grace Duvall sallied
+forth, determined to find out two things&mdash;first,
+the position occupied by Alphonse Valentin
+in the affair of the kidnapping; secondly, the identity
+of the man who had stolen the box of cigarettes
+from Valentin's room, and gone with them
+to the house in the Avenue Kleber. The latter
+incident seemed trivial enough, at first sight; yet
+she reasoned that no one would risk arrest on the
+score of burglary, to steal anything of such trifling
+value, without an excellent reason.</p>
+
+<p>She had a short conference with Monsieur
+Lefevre, before she left the house, and told him
+of the events of the previous night. The Prefect
+seemed greatly interested.</p>
+
+<p>"Could you identify the man who stole the
+cigarettes?" he asked.</p>
+
+<p>"Easily. I had a splendid view of his face."</p>
+
+<p>"Then go to Mr. Stapleton's house and take a<span class='pagenum'><a name="Page_61" id="Page_61">[61]</a></span>
+look at all the servants. You may find him
+among them."</p>
+
+<p>"I had intended to do so, this morning."</p>
+
+<p>The Prefect smiled. "I do not know what
+your investigations will lead to, but they seem
+promising. I have a dozen men working on the
+case; yet so far they have not made the least
+progress. Their efforts, however, are directed
+toward finding the child. They are searching the
+city with the utmost care. We believe that by
+discovering the missing boy, we shall also find the
+persons who committed the crime."</p>
+
+<p>"Have you no one under suspicion?"</p>
+
+<p>"No one. The nurse, Mary Lanahan, is of
+course being closely watched; also the chauffeur,
+Fran&ccedil;ois. My men report, however, that he gave
+them the slip for an hour, last night. I have an
+idea that he may prove to be the one who took
+the cigarettes."</p>
+
+<p>"Can you imagine any reason for his having
+done so?"</p>
+
+<p>"I confess, my child, that I cannot. It seems
+utterly absurd; unless, indeed, there was something
+else concealed in the box."</p>
+
+<p>"What?"</p>
+
+<p>The Prefect laughed. "I cannot imagine. But<span class='pagenum'><a name="Page_62" id="Page_62">[62]</a></span>
+if you can identify the man, we shall no doubt find
+out. As for the matter of Alphonse Valentin,
+we have already had him under observation. So
+far as we can learn, he is merely a chauffeur, out
+of work, who seems to be somewhat in love with
+the nurse."</p>
+
+<p>"Then his actions have not been suspicious,
+during the past week?"</p>
+
+<p>"Not in the least. He has hung around the
+Stapleton house for several days, asking for news
+of the Lanahan woman; but that is all. We attribute
+his actions to a natural anxiety over her
+illness."</p>
+
+<p>Grace left the house, by no means satisfied with
+the progress she was making. Her interview with
+Mary Lanahan, and subsequent visit to the scene
+of the crime, told her nothing she had not already
+known. Her greatest disappointment, however,
+came when she had Mrs. Stapleton bring in
+Fran&ccedil;ois, ostensibly to question him about his part
+in the affair. She saw at once that he was not
+the man who had broken into Alphonse Valentin's
+room on the night before. This man had been
+heavily bearded and tall. Fran&ccedil;ois was smooth
+shaved and rather short. Mrs. Stapleton assured
+her that none of her servants resembled in the<span class='pagenum'><a name="Page_63" id="Page_63">[63]</a></span>
+least her description of the burglar. She left the
+house, greatly dissatisfied, after satisfying herself
+that this was the case.</p>
+
+<p>Her visit to the house of Alphonse Valentin
+that afternoon was productive of no greater results.
+The man was out. The woman who
+opened the door&mdash;the same one who had admitted
+her the previous evening&mdash;regarded her
+with ill-concealed suspicion, and informed her
+that she had no idea when her lodger would return.
+Grace left, determined to try again the
+following day.</p>
+
+<p>Throughout the whole evening she hung about
+the Stapleton house, hoping again to see the man
+with the heavy beard who had disappeared within
+the night before; but he did not put in an appearance.
+Grace began to feel discouraged.
+She thought of her lilac bushes, at home, of Aunt
+Lucy feeding the chickens, of the dogs, the sweet
+call of the wood robins among the poplar trees
+on the lawn, and half wished that she had stayed
+at home and left to Richard the apparently hopeless
+task of finding the abductors of little Jack
+Stapleton.</p>
+
+<p>What, after all, could she hope to do, where
+the entire police force of Paris had failed? The<span class='pagenum'><a name="Page_64" id="Page_64">[64]</a></span>
+thing was absurd. Monsieur Lefevre had overrated
+her abilities. She heard the sound of church
+bells, striking the hour of ten, and decided to go
+home and forget the whole affair until tomorrow.
+Tomorrow&mdash;the day Richard must arrive!
+How she longed to be with him! This stupid interruption
+of their honeymoon seemed peculiarly
+cruel, now that over a week had elapsed since
+they had seen each other. She wondered if she
+would meet him, the next day. Then she thought
+of her changed appearance, of her hair, dyed a
+jet black, and worn in a new and to her mind
+unbecoming fashion, of her darkened complexion,
+her extremely French costume, her heavy veil,
+and laughed. If Richard did see her, here in
+Paris, when he fully believed her to be peacefully
+tending her flower beds at home, he would never
+believe the evidence of his senses.</p>
+
+<p>She was strolling toward the Champs &Eacute;lys&eacute;es,
+lost in thought, when suddenly she heard the soft
+throbbing of a high-powered motor car, as it
+came up the street behind her. She turned and
+glanced toward it; but the brilliant glare of the
+electric headlights blinded her. She could see
+nothing, except that the car was moving very
+slowly.</p>
+
+<p><span class='pagenum'><a name="Page_65" id="Page_65">[65]</a></span>Suddenly it stopped, almost abreast of her, and
+a tall man leaped to the sidewalk. Before she
+had an opportunity so much as to glance in his
+direction, he came swiftly up behind her, threw
+his arm about her neck, and choked her into unconsciousness.
+Her last sensation was of being
+lifted bodily into the already moving car, and
+then the feeling of rapid motion, quickly blotted
+out by the coming of insensibility.</p>
+
+<p>When she returned to consciousness, it was
+broad daylight. She lay upon a small wooden
+bed, in a low-ceilinged little room, the only furniture
+of which was a small chest of drawers and
+a chair. Upon this chair sat a large man, his
+face so thoroughly hidden by a mask that his
+features were quite unrecognizable. He was regarding
+her with keen scrutiny.</p>
+
+<p>"Oh&mdash;what&mdash;where am I?" she gasped.</p>
+
+<p>The man hesitated for a moment, then slowly
+spoke. "Where you are, mademoiselle, is of no
+importance. Attend to what I have to say."</p>
+
+<p>Grace made no reply. There seemed nothing
+that she could say. She sat up and gazed at the
+man, half dazed. Her head swam. She felt
+that she had been drugged.</p>
+
+<p>"Ten days ago," the man went on, in a cold<span class='pagenum'><a name="Page_66" id="Page_66">[66]</a></span>
+and menacing voice, "the child of Monsieur
+Stapleton was taken from his nurse in the Bois
+de Boulogne. You are trying to find that child."</p>
+
+<p>"But&mdash;" Grace made a movement of protest.</p>
+
+<p>"It is useless to deny it. You have been watched."</p>
+
+<p>Grace gasped in silence.</p>
+
+<p>"I desire to send a message to the boy's father,
+and I have chosen you to take it to him. I have
+selected you, because to send one of my own men
+would doubtless result in his arrest. That is why
+you have been brought here."</p>
+
+<p>"The&mdash;the child is safe?" asked Grace.</p>
+
+<p>"Perfectly. You shall see for yourself." He
+motioned to the window.</p>
+
+<p>Grace rose, and looked out. The view
+comprised a bit of garden, surrounded by
+bushes. She could see nothing beyond&mdash;nothing
+that would enable her in any way to identify
+the place. On the tiny plat of grass in the
+garden sat a child&mdash;a little girl, playing with
+a small black and white spaniel. Her dark hair
+was drawn tightly beneath a pink sunbonnet. Her
+dress, her whole appearance, was that of a peasant
+child.</p>
+
+<p>Grace turned from the window, bewildered.
+"I see nothing," she said, "except a little girl&mdash;"</p>
+
+<p><span class='pagenum'><a name="Page_67" id="Page_67">[67]</a></span>"That is the child of Monsieur Stapleton," the
+man said. "Now attend to the message."</p>
+
+<p>She sat down again, wondering.</p>
+
+<p>"Tell the boy's father this: He will leave his
+house tomorrow evening, in his automobile, at
+eight o'clock. He will bring with him, in a
+package, the sum of five hundred thousand francs&mdash;one
+hundred thousand dollars. He will have
+with him, in the automobile, no one but himself
+and his chauffeur. He will leave Paris by the
+Porte de Versailles, and drive along the road to
+Versailles at a speed of twelve miles an hour.
+Somewhere upon that road, among the many automobiles
+that will pass him, will be one, from
+which a blue light will flash, as it approaches him.
+It will also slow up. He will toss the package
+of bank notes into that car, and drive on. If the
+package contains the sum of five hundred thousand
+francs, he will find his child at his house,
+upon his return. If not, or if these instructions
+are not carried out to the letter&mdash;if there is any
+attempt made at pursuit&mdash;the child will not be
+there, and you can tell him that he will be given
+but one more chance. After that, the boy will die."</p>
+
+<p>The man in the mask made this gruesome
+statement with the utmost coolness.</p>
+
+<p><span class='pagenum'><a name="Page_68" id="Page_68">[68]</a></span>Grace listened, aghast at the cruelty of his
+words, and at the same time struck by the extreme
+ingenuity of the plan. To catch the perpetrators
+of the crime, under these circumstances, seemed
+impossible. A rapidly moving automobile&mdash;one
+of a hundred. An instant's flash of a blue light
+in passing&mdash;the tossing into the car of the money&mdash;and
+it would speed away into the darkness, beyond
+any hope of detection. Should Mr. Stapleton
+have others in his car&mdash;should he have his car
+followed by a second, containing armed men, the
+occupants of the kidnapper's machine would no
+doubt refuse to give the signal, and nothing would
+be accomplished. It would be impracticable to
+line the road, for a possible distance of twenty
+miles, with gendarmes, nor could their presence
+accomplish anything, beyond putting the kidnappers
+on guard, and preventing the carrying out
+of the plan.</p>
+
+<p>The weakest point in the whole scheme seemed,
+to Grace at least, the delivery of the child to Mr.
+Stapleton, provided he paid the money demanded.
+Just how that was to be accomplished, without
+subjecting the person who brought the boy to
+arrest, she did not see. A moment's reflection,
+however, showed her that a stranger might be<span class='pagenum'><a name="Page_69" id="Page_69">[69]</a></span>
+employed, at any point, who for a few francs
+would agree to take the child to the house. She
+turned to the man before her with feelings not
+devoid of admiration.</p>
+
+<p>"How can Mr. Stapleton know that you will
+do as you say?"</p>
+
+<p>The man shrugged his shoulders. "That is a
+chance he must take. If he does not believe that
+the child will be delivered to him, provided he
+pays the money, he had better not pay it. But
+if he does his part, I shall do mine&mdash;and this I
+swear by the memory of my mother!"</p>
+
+<p>Grace shuddered. A wretch of this sort, talking
+about the memory of his mother! "Very
+well," she said quietly, "I will take your message."</p>
+
+<p>"Good! You will not leave here, of course,
+until it is dark&mdash;tonight. You will be blindfolded,
+and conducted to some point in the city. From
+there, you can make your way to Monsieur Stapleton's
+house." He rose, and went toward the
+door. "Make no attempt to escape. It will be
+useless. Any attempts on the part of the police
+to interfere with the plan I have outlined will
+result in nothing. Food will be sent in to you at
+once. Good morning."</p>
+
+<p><span class='pagenum'><a name="Page_70" id="Page_70">[70]</a></span>It was close to ten o'clock that night, as nearly
+as Grace could judge, when she was led a considerable
+distance blindfolded, to a closed automobile,
+and driven away. She could form no idea
+of her whereabouts. The car continued on its
+way, for over an hour. Once she attempted to
+snatch the bandage from her eyes; but a hand
+was placed upon her arm by another occupant of
+the machine, and a low voice warned her to
+desist.</p>
+
+<p>After an interminable ride, the car suddenly
+stopped, and she felt the man at her side slip
+away from her and open the door. Instantly she
+snatched the bandage from her eyes. The man
+had disappeared. She stepped to the sidewalk,
+and looked about. She was standing upon a
+brightly lighted street, which seemed somehow
+familiar to her. The man on the box of the
+cab glanced down at her with a look of curious
+interest. She saw his face clearly, in the light of
+the street. It was the heavily bearded man whom
+she had seen take the box of cigarettes from the
+room of Alphonse Valentin two nights before.</p>
+
+<p>Grace stood with the bandage which had encircled
+her eyes, still in one hand. Suddenly she
+saw a dark figure uncoil itself from the rear of<span class='pagenum'><a name="Page_71" id="Page_71">[71]</a></span>
+the car, and drop noiselessly to the pavement as
+the machine started off. She gave a low cry of
+surprise. The man came up to her, a grim smile
+upon his face. It was Alphonse Valentin.</p>

+<h2>CHAPTER V</h2>
+
+<p class="cap extraspacetop">JOHN STAPLETON, the millionaire banker,
+accompanied by Richard Duvall, arrived in
+Paris early in the afternoon, and went at
+once to the former's house in the Avenue Kleber.</p>
+
+<p>Upon their arrival, Duvall waited for sometime,
+while the distressed husband and wife were
+closeted together upstairs. At last they descended
+to the library, and Duvall was presented to Mrs.
+Stapleton.</p>
+
+<p>The joy which her husband's arrival had caused
+her sent a new glow of hope to her careworn
+cheeks, and she greeted the detective most cordially.
+Clearly she felt that now something would
+at last be done, to find her missing child.</p>
+
+<p>Duvall's first questions related to Mary Lanahan,
+the nurse. He was relieved to find that she
+had quite recovered from her sudden illness.</p>
+
+<p>"Will you kindly have her brought here, Mrs.
+Stapleton?" he asked. "I would like to question
+her."</p>
+
+<p><span class='pagenum'><a name="Page_73" id="Page_73">[73]</a></span>In a few moments the nurse appeared. She
+was an extremely good-looking girl, smart and
+well dressed. Duvall recognized in her frank
+face, her clear blue eyes, the same appearance of
+honesty which had impressed him during his interview
+with Patrick Lanahan, her father.</p>
+
+<p>"Mary," said Mrs. Stapleton, "this is Mr.
+Duvall. He is trying to find Jack for us. Tell
+him your story."</p>
+
+<p>The girl turned to Duvall, who had risen. "I
+can hardly expect you to believe what I am going
+to say, Mr. Duvall, yet I assure you that it is
+the solemn truth."</p>
+
+<p>"Go ahead, Miss Lanahan," said the detective.
+"I am prepared to believe whatever you may
+say."</p>
+
+<p>The girl sat down, at Mrs. Stapleton's request.
+She still was somewhat weak, from her recent illness.</p>
+
+<p>"It was a week ago last Wednesday. I left
+the house with Master Jack at half-past ten, and
+we drove to the Bois."</p>
+
+<p>"Just a moment, please." Duvall stopped her
+with a quick gesture. "How long had you been
+going to the Bois in this way?"</p>
+
+<p>"Over six weeks."</p>
+
+<p><span class='pagenum'><a name="Page_74" id="Page_74">[74]</a></span>"And you always left about the same time&mdash;half-past
+ten?"</p>
+
+<p>"Always."</p>
+
+<p>"Who accompanied you besides the child?"</p>
+
+<p>"Fran&ccedil;ois&mdash;the chauffeur."</p>
+
+<p>"Always?"</p>
+
+<p>"Yes."</p>
+
+<p>Duvall turned to Mrs. Stapleton. "How
+long has this man Fran&ccedil;ois been in your employ?"</p>
+
+<p>"A year&mdash;in June."</p>
+
+<p>"You have found him honest, reliable?"</p>
+
+<p>"Always. Otherwise I should not have kept
+him."</p>
+
+<p>The detective turned to Mary Lanahan. "Go
+ahead, please," he said.</p>
+
+<p>"We reached the Bois shortly before eleven&mdash;Fran&ccedil;ois
+had orders to go slowly, when Master
+Jack was in the machine&mdash;and drove about for
+fifteen minutes. Then we stopped at the place
+where we were in the habit of playing."</p>
+
+<p>"Was it always the same place?"</p>
+
+<p>"Yes. There is a smooth field of grass there,
+and a clump of trees by the road, where the machine
+always waited."</p>
+
+<p>"Go on."</p>
+
+<p><span class='pagenum'><a name="Page_75" id="Page_75">[75]</a></span>"We left the car, and walked out over the
+grass. Master Jack had a big rubber ball, and
+he was kicking it along, and running after it.
+Sometimes he would kick it to me, and I would
+throw it back to him. We played about in that
+way for over half an hour. Mrs. Stapleton
+wished the boy to have the exercise."</p>
+
+<p>"I see. And you generally played about in
+the same place?"</p>
+
+<p>"Yes."</p>
+
+<p>"How far from the road?"</p>
+
+<p>"About three hundred feet."</p>
+
+<p>"And from the nearest bushes, or woods?"</p>
+
+<p>"A little more than that, I should say."</p>
+
+<p>"You could see Fran&ccedil;ois, in the machine, from
+where you were?"</p>
+
+<p>"Yes, I could see the machine. I could not
+always see Fran&ccedil;ois; for sometimes he would get
+out, and walk about, or sit under the trees and
+smoke a cigarette."</p>
+
+<p>"Do you remember noticing him, on this particular
+morning?"</p>
+
+<p>"Yes. I saw him sitting in the machine."</p>
+
+<p>"What was he doing?"</p>
+
+<p>"Reading a newspaper."</p>
+
+<p>"Had he ever done that before?"</p>
+
+<p><span class='pagenum'><a name="Page_76" id="Page_76">[76]</a></span>The girl hesitated, as though a new idea had
+come to her. "No&mdash;I cannot remember that he
+ever had."</p>
+
+<p>"Very well. Go ahead with your story."</p>
+
+<p>"Well&mdash;after we had played for about half
+an hour&mdash;I got tired and sat down on the grass.
+Master Jack still kept playing about with the ball.
+I sat idly, looking at the sky, the road&mdash;dreaming&mdash;"</p>
+
+<p>"About what?" interrupted the detective, suddenly.</p>
+
+<p>The girl colored. "About&mdash;about some people
+I know."</p>
+
+<p>"Go ahead."</p>
+
+<p>"I heard the boy playing, behind me. Then
+I looked around&mdash;and&mdash;he was gone!" The
+nurse made this statement in a voice so full of
+awe that it carried conviction to her hearers.
+Duvall felt that, whatever the real facts of the
+disappearance of the child, this woman's story
+was true.</p>
+
+<p>"What did you do then?"</p>
+
+<p>"I stood up and looked about. I thought Master
+Jack was hiding from me&mdash;playing a joke on
+me. Then I realized that there was no place that
+he could hide. The nearest trees were too far<span class='pagenum'><a name="Page_77" id="Page_77">[77]</a></span>
+off. He could not have reached them. I called
+and called. I was very much frightened."</p>
+
+<p>"Fran&ccedil;ois, who heard me, came running over
+the grass. I asked him if he had seen Master
+Jack. He said, no, that he had not seen anyone.
+After that we searched everywhere&mdash;in the
+woods, along the road&mdash;for nearly an hour, but
+could find nothing. Then we came home, and
+told Mrs. Stapleton." The girl looked at her
+employers in fright.</p>
+
+<p>"What about the rubber ball?" Duvall asked,
+suddenly.</p>
+
+<p>"It&mdash;it was gone."</p>
+
+<p>"Then it is clear that the child must have been
+taken away peaceably, without objection on his
+part. Had he struggled, cried, he would have
+dropped the ball, would he not?"</p>
+
+<p>"I suppose so."</p>
+
+<p>"How long was your head turned from him&mdash;while
+you were&mdash;dreaming?"</p>
+
+<p>"About a minute."</p>
+
+<p>"Not more?"</p>
+
+<p>"No."</p>
+
+<p>"How do you estimate the time so closely?"</p>
+
+<p>"I'm sure it could not have been longer. A
+minute is quite a long time."</p>
+
+<p><span class='pagenum'><a name="Page_78" id="Page_78">[78]</a></span>"What time was it when you got back to the
+house?"</p>
+
+<p>"About&mdash;about one o'clock, I think." The girl
+turned to Mrs. Stapleton for confirmation of her
+answer.</p>
+
+<p>"It was a quarter-past one," said Mrs. Stapleton,
+promptly. "I noted the time particularly, because
+it was later than usual. Mary had orders
+to bring Jack back for luncheon not later than
+one."</p>
+
+<p>Duvall began to make some figures on a piece
+of paper. "You fix the time of the boy's disappearance
+at 11.30. You say you hunted for him
+an hour. That would be 12.30." He looked at
+the girl searchingly. "You arrived home at 1.15.
+That would mean that it took 45 minutes to
+get here." He turned to Stapleton. "Please
+send for your chauffeur, Fran&ccedil;ois."</p>
+
+<p>Mr. Stapleton rang a bell, and ordered the
+servant who responded to send in the chauffeur.
+Meanwhile Mary Lanahan was regarding Duvall
+with nervous apprehension.</p>
+
+<p>"We must have hunted for him longer than I
+thought," she said, at length.</p>
+
+<p>Duvall made no reply, but waited until the arrival
+of the chauffeur. He proved to be a short,<span class='pagenum'><a name="Page_79" id="Page_79">[79]</a></span>
+heavily built man, with long powerful arms, and
+a swarthy face&mdash;evidently from the south of
+France. His countenance was stolid and emotionless.
+He appeared the well trained servant.</p>
+
+<p>Duvall addressed him at once. "How long
+would it take you, my man, driving fast, to reach
+this house from the spot in the Bois where Master
+Jack was lost?"</p>
+
+<p>The man responded at once. "Ten minutes,"
+he said, "easily."</p>
+
+<p>"What time was it when this woman," the
+detective indicated the nurse, "called to you, on
+discovering that the child was gone?"</p>
+
+<p>"I do not know."</p>
+
+<p>"Have you no idea?"</p>
+
+<p>"It must have been about twelve o'clock. We
+hunted for the boy till about one&mdash;then came
+home."</p>
+
+<p>"The nurse says it was half-past eleven."</p>
+
+<p>The man shrugged his shoulders. "It may
+have been. I did not observe the time."</p>
+
+<p>"What were you doing?"</p>
+
+<p>"I was asleep."</p>
+
+<p>Mr. Stapleton started. "Asleep?" he demanded,
+angrily.</p>
+
+<p>The man nodded. "The day was warm. I<span class='pagenum'><a name="Page_80" id="Page_80">[80]</a></span>
+had nothing to do. For a time I read the paper.
+I must have dozed in my seat; for, the next thing
+I knew, the nurse was calling to me, and the boy
+was gone."</p>
+
+<p>Duvall frowned. "Then you could not say
+whether anyone else was near the nurse and the
+boy, at the time he was kidnapped?"</p>
+
+<p>"No, monsieur. I could not."</p>
+
+<p>"That will do." The detective turned to Mr.
+Stapleton. "Have your man drive us to the
+place where all this occurred."</p>
+
+<p>The banker gave the man the order, and he
+left the room. Then Duvall turned again to
+Mary Lanahan.</p>
+
+<p>"You were taken suddenly ill one day last week.
+Tell us about it."</p>
+
+<p>The woman looked up. "It was very mysterious,
+sir. I went out for a walk. At a caf&eacute; in
+the Rue St. Honor&eacute; I had a cup of chocolate."</p>
+
+<p>"Alone?" asked the detective, sharply.</p>
+
+<p>The woman colored. "No," she faltered. "I&mdash;I
+was with a friend."</p>
+
+<p>"Who?"</p>
+
+<p>"A&mdash;a gentleman I know." She glanced fearfully
+at Mr. Stapleton. "I&mdash;I would rather not
+give his name."</p>
+
+<p><span class='pagenum'><a name="Page_81" id="Page_81">[81]</a></span>"Was it Alphonse Valentin?" asked Duvall,
+quickly.</p>
+
+<p>The woman colored still more deeply. "Yes,"
+she replied, in scarcely audible tones.</p>
+
+<p>The banker regarded her in surprise. "Alphonse
+Valentin!" he cried. "The fellow I discharged
+last year, for dishonesty? Mr. Duvall&mdash;he's
+your man!"</p>
+
+<p>"No&mdash;no!" exclaimed the nurse, excitedly.
+"He knows nothing of the matter&mdash;nothing!"</p>
+
+<p>"That remains to be seen," remarked Duvall,
+slowly. "Where did you meet this fellow, Valentin?"</p>
+
+<p>"At the caf&eacute; in the Rue St. Honor&eacute;."</p>
+
+<p>"You had met him there frequently before?"</p>
+
+<p>"Yes."</p>
+
+<p>"After you left the caf&eacute;, what did you
+do?"</p>
+
+<p>"We walked to the Champs &Eacute;lys&eacute;es and sat
+on a bench, talking. Suddenly I felt very ill. Mr.
+Valentin called a cab and sent me home."</p>
+
+<p>"Give me the address of this caf&eacute;, please."</p>
+
+<p>The woman did so. As Duvall was entering
+it in his notebook, a servant announced that the
+automobile was at the door.</p>
+
+<p><span class='pagenum'><a name="Page_82" id="Page_82">[82]</a></span>In fifteen minutes the party, consisting of Mr.
+Stapleton, Duvall, and Mary Lanahan, were leaving
+the car at the spot in the Bois de Boulogne
+which had been the scene of the kidnapping.
+Fran&ccedil;ois was ordered to drive his machine to the
+exact spot, as nearly as he could tell, that it had
+occupied on the previous occasion. Mary Lanahan
+led the others to the place on the grass where
+she had sat.</p>
+
+<p>It was evident at once that the distances she
+had named in telling her story were less, if anything,
+than the actual facts. It was quite impossible
+to see how, in any way, the child could
+have been taken from the spot she indicated, to
+the woods, without consuming a considerable
+period of time&mdash;five minutes, at least. To believe
+that the nurse could have turned away her
+head for a moment, and then looked around to
+find the boy gone seemed the sheerest fabric of
+the imagination; yet the woman, in repeating her
+story, stuck to it with a grim pertinacity which,
+it seemed, could come only from the knowledge
+that she was telling the truth.</p>
+
+<p>Ten days had elapsed since the boy had been
+kidnapped. It seemed almost useless to search
+the spot for any evidences of the crime. Yet<span class='pagenum'><a name="Page_83" id="Page_83">[83]</a></span>
+Duvall began to go over the ground where the
+nurse testified that she had sat, with the most
+minute care. Inch by inch, he examined the turf,
+subjecting almost every blade of grass to a separate
+examination. The operation required over
+half an hour, and both Mr. Stapleton and the
+nurse grew tired of watching him, and strolled
+about aimlessly.</p>
+
+<p>Hence they did not see him pick up a tiny object
+from the grass. It was a half-smoked cigarette,
+dirty and almost falling to pieces from the
+action of the weather, yet held together by a
+slender tip of gold.</p>
+
+<p>He placed it carefully within his pocketbook,
+and rose. "Nothing more to be done here," he
+called to Mr. Stapleton, and in a moment the
+three were proceeding toward the waiting automobile.</p>
+
+<p>Upon the return to the house, Mr. Stapleton
+drew the detective into his library. "Have you
+discovered anything, Mr. Duvall?" he inquired,
+making an effort to conceal his almost frantic
+anxiety.</p>
+
+<p>"I do not know&mdash;yet. I may have a clue; but
+I am not sure."</p>
+
+<p>"What do you think of the woman's story?"</p>
+
+<p><span class='pagenum'><a name="Page_84" id="Page_84">[84]</a></span>"It seems impossible to believe it."</p>
+
+<p>"You think, then, that she had a hand in the
+matter&mdash;she and this fellow Valentin?"</p>
+
+<p>"It begins to look like it."</p>
+
+<p>"On what do you base your conclusions, Mr.
+Duvall? I cannot bring myself to believe that
+Mary Lanahan is lying, ready as I am to suspect
+this fellow Valentin."</p>
+
+<p>"First, Mr. Stapleton, on the facts themselves.
+The boy could not have been taken away without
+her knowledge. Secondly, upon some minor
+matters&mdash;her error of half an hour, in telling her
+story, for instance."</p>
+
+<p>"I am sorry, Mr. Duvall, but I cannot believe
+that you are right. I'd suspect Valentin, at once;
+but if Mary Lanahan is not telling the truth,
+then my experience of twenty years in judging
+human nature has been wasted."</p>
+
+<p>"Yet you yourself heard her admit that she was
+with Valentin only last Friday, the day she was
+taken ill."</p>
+
+<p>"Yes. That is true." Mr. Stapleton passed
+his hand uncertainly across his forehead. "It's
+too much for me."</p>
+
+<p>"Let me have a word with the nurse, alone,
+before I go," asked Duvall.</p>
+
+<p><span class='pagenum'><a name="Page_85" id="Page_85">[85]</a></span>"Certainly," replied the banker. "I'll send her
+in to you."</p>
+
+<p>When Mary Lanahan entered the room, the
+detective went up to her and eyed her sternly.
+"Was Alphonse Valentin with you at any time,
+in the Bois, that day?"</p>
+
+<p>"No," replied the girl, steadily.</p>
+
+<p>"Does he smoke gold-tipped cigarettes?" asked
+Duvall, suddenly.</p>
+
+<p>The effect of this question upon the nurse was
+startling. She recoiled as though the detective
+had struck her. "He&mdash;he does not smoke at all,"
+she gasped, her face gray with fear.</p>
+
+<p>"Don't lie to me!"</p>
+
+<p>"He does not smoke at all," repeated the girl,
+almost mechanically, and stood confronting him
+with a defiant air.</p>
+
+<p>"Very well. That is all." The detective
+turned from the room and left the house.</p>
+
+<p>He did not, however, go very far. It was
+rapidly becoming dark. He passed down the
+street until he judged he was out of sight of the
+house, then slowly retraced his steps upon the
+other side, until he had reached a point nearly
+opposite the small iron gateway which served as
+the servants' entrance to Mr. Stapleton's house.<span class='pagenum'><a name="Page_86" id="Page_86">[86]</a></span>
+Here, hidden behind a tree, he watched for perhaps
+half an hour.</p>
+
+<p>At the expiration of this period, he was rewarded
+by seeing a young man, evidently an
+under servant, emerge from the gateway. Duvall
+watched him as he proceeded down the
+street, then began to follow him.</p>
+
+<p>The young man seemed in no great hurry, and
+at the junction of the avenue with the Champs
+&Eacute;lys&eacute;es, Duvall accosted him, speaking in
+French.</p>
+
+<p>"Do you want to earn twenty francs, my
+friend?" he asked pleasantly.</p>
+
+<p>The boy regarded him with a quizzical smile.
+"Who does not, Monsieur?" he replied.</p>
+
+<p>"Let me see the note you have in your hand."</p>
+
+<p>The boy drew back suddenly, and made as
+though to thrust the letter into his pocket. "It
+is impossible, Monsieur," he began.</p>
+
+<p>Duvall took out a gold twenty-franc piece. "I
+intend to have the letter, my man. If you will
+give it to me peaceably, here are the twenty francs;
+if not, I shall be obliged to take it from you by
+force."</p>
+
+<p>The boy regarded the detective for a moment,
+as though contemplating flight. Duvall seized<span class='pagenum'><a name="Page_87" id="Page_87">[87]</a></span>
+him by the collar. "Give me the note," he cried,
+"or I'll call a gendarme and have you placed
+under arrest!"</p>
+
+<p>The boy allowed the letter to drop to the pavement,
+seized the twenty-franc piece, and took to
+his heels.</p>
+
+<p>Duvall picked it up. As he had expected, it
+was addressed to Alphonse Valentin, &mdash;&mdash; Boulevard
+St. Michel. He had waited, on the chance
+that Mary Lanahan would lose no time in warning
+her probable confederate.</p>
+
+<p>The letter gave him the man's address. That
+was so much accomplished, at least. Then he tore
+it open, and read the contents. They proved more
+mystifying than anything that he had yet encountered
+in this mysterious affair.</p>
+
+<p>"Destroy the cigarettes!" These three words
+comprised the entire contents of the note.</p>
+

+<h2>CHAPTER VI</h2>
+
+<p class="cap extraspacetop">ALPHONSE VALENTIN came up to
+Grace and took her roughly by the arm.
+"Come with me," he said, and started
+up the street.</p>
+
+<p>At first she felt inclined to resist him. A signal
+to a passing gendarme, and she could have
+had the man placed under arrest. Monsieur Lefevre
+had taken care to provide her with credentials
+that would insure her obtaining instant assistance
+from any member of the police.</p>
+
+<p>Then another thought came to her. This man
+Valentin she very much desired to see. His position,
+clinging to the rear of the automobile,
+indicated that he was in all probability not a
+confederate of the kidnappers. Just what he
+was, she could not imagine. She determined to
+go along with him, and hear what he had to
+say.</p>
+
+<p>A few minutes' walk brought them to the man's<span class='pagenum'><a name="Page_89" id="Page_89">[89]</a></span>
+lodgings. For some reason, which she did not
+understand, the automobile in which she had been
+a prisoner had stopped on the Boulevard St.
+Michel within a short distance of Valentin's
+rooms.</p>
+
+<p>When they reached the house, Valentin, instead
+of opening the door with a key, rang the
+bell. The woman who had previously admitted
+Grace came to the door. Valentin nodded.</p>
+
+<p>"Is this the woman?" he asked.</p>
+
+<p>"Yes," said the landlady, recognizing her at
+once. "This is the one."</p>
+
+<p>"Good!" Valentin closed the door and led
+the way to his room. Grace followed, wondering
+what the man intended to do.</p>
+
+<p>"Why have you come here twice during the
+past two days?" he asked, abruptly, after he had
+lit the lamp and carefully shut the door.</p>
+
+<p>Grace determined to be quite frank with him.
+"I wanted to ask you some questions, Monsieur
+Valentin," she replied.</p>
+
+<p>"Ha! You know my name?"</p>
+
+<p>"Certainly."</p>
+
+<p>He appeared somewhat uneasy. "What are
+you up to?"</p>
+
+<p>"I am trying to find Mr. Stapleton's child."</p>
+
+<p><span class='pagenum'><a name="Page_90" id="Page_90">[90]</a></span>A queer smile came over the fellow's face. "Is
+that why you stole the cigarettes?" he asked.</p>
+
+<p>"I did not steal them. They were taken by a
+man with a black beard, who came in through
+the window when I was here."</p>
+
+<p>"A black beard?" He smiled incredulously.
+"And you let him take them."</p>
+
+<p>"Yes. Why not? Were they of such great
+value?"</p>
+
+<p>He glanced about uneasily, but did not reply
+to her question. "Who was the man?" he presently
+asked.</p>
+
+<p>"I do not know. I followed him. He entered
+Mr. Stapleton's house."</p>
+
+<p>"Sacr&eacute;! It must have been Fran&ccedil;ois!"</p>
+
+<p>"Hardly. Fran&ccedil;ois has no beard."</p>
+
+<p>"But he might have been disguised." He
+seemed very much perturbed. "What a pity I
+was so careless!"</p>
+
+<p>"Monsieur Valentin, will you please tell me
+what those cigarettes have to do with the kidnapping
+of Mr. Stapleton's child?"</p>
+
+<p>He looked at her closely for a moment.
+"Everything," he answered gloomily, "and&mdash;nothing.
+I was a fool to have left them
+here."</p>
+
+<p><span class='pagenum'><a name="Page_91" id="Page_91">[91]</a></span>Grace began to feel more and more composed.
+This man did not talk like one of the band of
+criminals. "Do you know where the child is?"
+she suddenly asked.</p>
+
+<p>"Perhaps." He observed her narrowly. "Do
+you?"</p>
+
+<p>"No. If I did, I should restore him to his
+poor mother."</p>
+
+<p>"What were you doing in that automobile?"</p>
+
+<p>"I was a prisoner. And you?"</p>
+
+<p>Again he evaded her question. "It is my own
+affair," he growled.</p>
+
+<p>"Did you not see who it was that drove the
+car?" she asked.</p>
+
+<p>Instead of replying, he flung himself into a
+chair. "Sit down, Mademoiselle, and tell me the
+whole story. If I find that you are frank with
+me, I promise to be equally so with you."</p>
+
+<p>Suddenly Grace felt an intuition that the man
+was honest. She determined to do as he asked.
+"Very well. I will tell you the truth. I am trying
+to recover Mr. Stapleton's child. Last night
+I was watching the house. I was seized from
+behind, thrown into an automobile, and taken&mdash;I
+do not know where. This morning a message
+to Mr. Stapleton was given me. Tonight I was<span class='pagenum'><a name="Page_92" id="Page_92">[92]</a></span>
+brought here, blindfolded, in an automobile.
+Then I met you. That is all I know."</p>
+
+<p>Valentin appeared disappointed. "Then you
+do not know where the child is?" he asked.</p>
+
+<p>"The child is where I was&mdash;I saw it."</p>
+
+<p>As Grace said this, her companion leaped excitedly
+from his chair. "Then we have them!"
+he cried.</p>
+
+<p>"I do not understand."</p>
+
+<p>"Mademoiselle, this evening I was watching
+Monsieur Stapleton's house. Like yourself, I desire
+to recover the child. I saw Fran&ccedil;ois leave in
+Monsieur Stapleton's automobile. I climbed in
+behind, as he left the house. It was dark. He
+did not see me. He drove out toward Versailles."</p>
+
+<p>"Toward Versailles?" exclaimed Grace.</p>
+
+<p>"Yes. Why do you seem so surprised."</p>
+
+<p>"Never mind. Go on."</p>
+
+<p>"After a time, he stopped by the roadside. I
+got out, and hid in the shadow of some trees.
+Presently you were brought, blindfolded, by a
+man, who entered the car with you. When it
+again started, I climbed on behind. That is how
+I came to meet you."</p>
+
+<p>"Then you don't know where the house is, from
+which I was brought?"</p>
+
+<p><span class='pagenum'><a name="Page_93" id="Page_93">[93]</a></span>"No. There are many houses&mdash;all about.
+There was no way of knowing, in the dark. Did
+you come far&mdash;when they brought you to the automobile?"</p>
+
+<p>"Yes. Several hundred yards, at least. But
+you know the spot, on the roadside?"</p>
+
+<p>"Yes. I can find it, without difficulty."</p>
+
+<p>"Monsieur Valentin, I have a plan&mdash;a very
+dangerous plan&mdash;for recovering Mr. Stapleton's
+boy. I cannot tell you what it is now. Tomorrow
+I will tell you&mdash;tomorrow afternoon. I shall
+want your assistance."</p>
+
+<p>"What am I to do?"</p>
+
+<p>"Can you drive an automobile?"</p>
+
+<p>The man smiled. "Decidedly. It is my profession."</p>
+
+<p>"Splendid! You will wait for me here, and I
+will come, and tell you what you are to do. I
+shall arrive not later than six o'clock." She rose.
+"Now I must go; but before I do so, tell me one
+thing. What is the mystery of the gold-tipped
+cigarettes?"</p>
+
+<p>Her question seemed to drive from Valentin's
+face all the good nature that had dwelt there the
+moment before. "I cannot tell you that," he
+growled. "You must not ask me. Let me advise<span class='pagenum'><a name="Page_94" id="Page_94">[94]</a></span>
+you to drop the matter of the cigarettes, and
+report your message to Mr. Stapleton at once."</p>
+
+<p>For a moment, Grace almost regretted her
+frankness. Suppose, after all, he should prove
+to be but a confederate of the kidnappers, in
+league with Mary Lanahan, the nurse, to spirit
+the boy away in the first place, and now sent by
+them, in the guise of a spy clinging to the rear of
+the automobile, to find out what step she proposed
+to take to capture them? She paused in
+indecision. Suddenly there was a tapping upon
+the door of the room.</p>
+
+<p>Valentin went to the door and cautiously opened
+it. The landlady stood on the landing outside.
+"There is a man to see you, at the door below,
+Monsieur," she said in a low tone.</p>
+
+<p>"Who is it?"</p>
+
+<p>"I do not know. He gives the name of Victor
+Girard."</p>
+
+<p>"Very well. Send him up."</p>
+
+<p>Grace heard the name&mdash;Victor Girard. A
+sudden wave of weakness swept over her. It was
+Richard! He had used the name frequently, in
+the past. She heard him ascending the short flight
+of stairs. There was no escape. Yet Monsieur
+Lefevre particularly insisted that he should not<span class='pagenum'><a name="Page_95" id="Page_95">[95]</a></span>
+recognize her. She hastily drew down her veil.
+"Get rid of him as soon as you can," she whispered
+to Valentin, and shrunk back into the
+shadow.</p>
+
+<p>Duvall came in, glancing sharply about him.
+He had been waiting to see Valentin since early
+in the evening, and had inquired for him twice
+before, only to find that he was out.</p>
+
+<p>"What can I do for you, Monsieur?" inquired
+Valentin.</p>
+
+<p>The detective drew the note from his pocket&mdash;the
+note which Mary Lanahan had sent to Valentin,
+and which Duvall had intercepted. "This
+is for you, Monsieur?" he asked, then suddenly
+paused, astounded. In the dim light, he caught
+sight of Grace, standing on the opposite side of
+the room, watching him closely. "I&mdash;I thought&mdash;Monsieur&mdash;I
+thought you were alone," he
+gasped, his eyes fixed on Grace as though he had
+seen a ghost. "I&mdash;I beg your pardon, but&mdash;"
+He was unable to proceed.</p>
+
+<p>Valentin looked at him in amazement. "What
+is it, my friend?" he asked sharply. "Tell me
+your business, if you please, and go. I have a
+visitor."</p>
+
+<p>"Yes&mdash;Monsieur&mdash;so&mdash;so I see." Duvall<span class='pagenum'><a name="Page_96" id="Page_96">[96]</a></span>
+pulled himself together with a mighty effort and
+turned his glance to Valentin. He had suffered
+a great shock. For a moment he would have
+been ready to swear that Grace, his dear wife,
+stood before him in the flesh&mdash;and yet the thing
+was an absurdity: Grace, with her golden
+brown hair, her clear complexion, was three
+thousand miles away! This woman, dark, typically
+French, was quite evidently an entirely different
+person; yet the resemblance was startling&mdash;he
+felt himself shaking in every fiber.</p>
+
+<p>"Well, Monsieur, give me the letter, since you
+say it is for me," he heard Valentin saying.</p>
+
+<p>In an instant he had recovered his self possession.
+"Here," he exclaimed, handing the note to
+the man before him. "It is from Mary Lanahan.
+I have read it."</p>
+
+<p>"You have read it, Monsieur!" Valentin exclaimed,
+angrily. "By what right, then, do you
+presume to read my letters?" He took the note
+and hurriedly read its contents. "Sacr&eacute;!" he exclaimed.
+"What does this mean?"</p>
+
+<p>"It means, my friend, that I want that box of
+gold-tipped cigarettes."</p>
+
+<p>Grace started. So Richard, too, was interested
+in the recovery of these mysterious cigarettes.<span class='pagenum'><a name="Page_97" id="Page_97">[97]</a></span>
+What on earth, she wondered, could it
+mean?</p>
+
+<p>"In the first place, Monsieur, let me inform you
+that I have no cigarettes, gold-tipped or otherwise.
+In the second place, I question your right
+to make any such demands."</p>
+
+<p>"Does not the note from Mary Lanahan request
+you to destroy them?"</p>
+
+<p>Valentin turned pale. "I tell you I have no
+such cigarettes!" he cried.</p>
+
+<p>"Are they not the sort, then, that you usually
+smoke?"</p>
+
+<p>"I do not smoke at all, Monsieur."</p>
+
+<p>Duvall laughed. "So you both tell the same
+story, it seems. My friend, I dislike to discuss
+these matters before a stranger." He glanced
+significantly at Grace.</p>
+
+<p>She dared not go. To speak&mdash;even to bid
+Valentin good evening, would, she felt sure, betray
+her. So she remained silent.</p>
+
+<p>"Then take yourself off. I certainly have no
+desire to discuss them. I tell you, I do not smoke&mdash;I
+have no cigarettes&mdash;that is enough!"</p>
+
+<p>"What does that note mean, then?" asked
+Duvall sternly.</p>
+
+<p>"That is Miss Lanahan's affair&mdash;and mine."</p>
+
+<p><span class='pagenum'><a name="Page_98" id="Page_98">[98]</a></span>Duvall drew out his pocketbook, and extracted
+from it the bit of cigarette stump, with the gold
+tip, which he had found that morning in the Bois
+de Boulogne. "Monsieur Valentin," he said, "I
+found this end of a cigarette at the exact place in
+the grass, in the Bois de Boulogne, where Mr.
+Stapleton's child and nurse were, when the boy
+was stolen. The chauffeur was asleep. You could
+readily have walked up, taken away the child,
+and no one would have been the wiser. The
+story of Mary Lanahan, that no one came near
+her, that the boy disappeared into thin air, is
+absurd. The presence of the half-smoked cigarette,
+of a kind which I have reason to believe
+you use, convinces me that you were there in the
+Bois, with the nurse, at the time of the kidnapping&mdash;if
+indeed you did not take an active part
+in it. The message from Mary Lanahan, which
+I have just handed you, directing you to destroy
+the cigarettes,&mdash;which, no doubt, she feared, after
+my questioning, might be used as evidence against
+you,&mdash;serves as strong additional proof. I believe
+that you know where Mr. Stapleton's child
+is."</p>
+
+<p>The statements which her husband made convinced
+Grace that she had made a mistake in confiding<span class='pagenum'><a name="Page_99" id="Page_99">[99]</a></span>
+in Valentin. She herself had seen the gold-tipped
+cigarettes on his table&mdash;had seen them
+stolen. It was not very conclusive evidence, she
+realized; but, taken with the nurse's letter, it was
+significant.</p>
+
+<p>Valentin, however, did not appear to be greatly
+alarmed by the detective's charges. "You are mistaken,
+Monsieur," he said quietly. "I know nothing
+about the affair."</p>
+
+<p>"Then what does this note mean?"</p>
+
+<p>"That I cannot tell you. And, if you have any
+other questions to ask, I beg that you will come
+again&mdash;at another time. I, as you see, am engaged
+for the moment." He indicated Grace
+with a glance.</p>
+
+<p>Duvall looked about, then turned to the door.
+His object in coming had been fulfilled. He had
+seen Valentin&mdash;located him&mdash;he hoped frightened
+him. It was one of his theories that a man,
+frightened by the knowledge that he is being
+closely pursued, is far more likely to make a false
+step, than one who fancies himself secure.</p>
+
+<p>He darted a curious glance at Grace, as he left
+the room; but her face, concealed in the shadow,
+told him nothing. Her silent presence filled him
+with strange disquietude. He stationed himself<span class='pagenum'><a name="Page_100" id="Page_100">[100]</a></span>
+outside the doorway of the house, determined
+to learn, if possible, who she was, by following
+her, when she left the place. He had not counted
+on Valentin's being with her.</p>
+
+<p>The two left the house together, and the man
+at once called a cab. Into this he put Grace,
+all the while eying Duvall savagely. The latter
+gave up all ideas of pursuing Grace, and returned,
+somewhat disgruntled, to his hotel. He had
+barely reached it, when a message was brought
+to him, summoning him to Mr. Stapleton's house.</p>
+
+<p>Grace, meanwhile, had driven at once to the
+banker's, and delivered to him the message with
+which she had been intrusted by the man in the
+black mask that morning.</p>
+
+<p>Mr. Stapleton's face grew more and more
+angry as she proceeded with her story. He
+jumped up, as soon as he learned the purport
+of it, and, ringing up Duvall's hotel, requested the
+detective to come to him at once. Then he turned
+to Grace.</p>
+
+<p>"You have no idea where this place is located?"</p>
+
+<p>"Not the slightest."</p>
+
+<p>"You say you saw my boy? He was safe?"</p>
+
+<p>"I saw a child, which I was told was yours,
+Mr. Stapleton. I did not recognize him, of<span class='pagenum'><a name="Page_101" id="Page_101">[101]</a></span>
+course. You know I have never seen your son.
+Also, he was dressed as a girl."</p>
+
+<p>Mr. Stapleton produced a photograph with
+nervous haste. "Was he like this?" he demanded.</p>
+
+<p>"Yes. It was the same." There was sufficient
+resemblance, even in the disguise the boy wore,
+for Grace to be practically certain of his
+identity.</p>
+
+<p>"How am I to know that these scoundrels will
+keep their word?" Mr. Stapleton groaned, his
+head on his hands.</p>
+
+<p>"Do you intend, then, to give them the
+money?"</p>
+
+<p>"Certainly. Do you suppose I would take any
+chances, for the matter of a hundred thousand
+dollars&mdash;or twice as much, for that matter?
+His mother and I are unable to sleep, to eat,
+to do anything in fact, under the strain of this
+thing. I shall by all means do as they ask."</p>
+
+<p>"But they will get away."</p>
+
+<p>"That is nothing to me. Let them. Once my
+boy is safe, I can spend another hundred thousand
+to catch them; but not now&mdash;when one false step
+might mean his death."</p>
+
+<p>"They won't harm him, Mr. Stapleton. They<span class='pagenum'><a name="Page_102" id="Page_102">[102]</a></span>
+are too anxious for the money, to let anything
+happen to him."</p>
+
+<p>"I'll take no chances."</p>
+
+<p>Grace rose. "Then I might as well be going,"
+she said. "I don't see that I can do anything
+more. I shall report the matter to the Prefect
+of Police at once."</p>
+
+<p>"Very well. And be good enough to say to
+him that I particularly desire that no steps be
+taken to prevent the carrying out of the plan.
+I shall pay this money and regain my boy. After
+that, the police may do as they like. Good evening."</p>
+
+<p>"Good evening." Grace left the house, feeling
+singularly disappointed, in spite of the fact that
+Mr. Stapleton's decision apparently meant that
+Richard's work in Paris, as well as her own, was
+likely to be brought to a sudden termination.</p>
+
+<p>As she was leaving the house, she saw Richard
+drive up in a cab. The sight of him filled her
+with joy; although she was forced to conceal it,
+and pass him by with a look of indifference. In
+the darkness, she knew she was safe. He recognized
+her of course,&mdash;recognized her, that is, as
+the woman he had seen in Valentin's room,&mdash;and
+her presence here at Mr. Stapleton's house<span class='pagenum'><a name="Page_103" id="Page_103">[103]</a></span>
+evidently filled him with surprise. For a moment,
+she thought he was about to speak to her, as he
+descended from his cab; but she turned away
+and hurried down the street, and when she looked
+back, he had entered the house.</p>

+<h2>CHAPTER VII</h2>
+
+<p class="cap extraspacetop">MR. STAPLETON was standing in the
+middle of the library, when Duvall entered.
+He turned to him excitedly.</p>
+
+<p>"Mr. Duvall," he said, "I have just heard news
+that I hope will restore my boy to me within the
+next twenty-four hours!"</p>
+
+<p>"From the woman who just left the house?"</p>
+
+<p>"Yes."</p>
+
+<p>"Who is she?"</p>
+
+<p>"An agent of the police."</p>
+
+<p>"Ah! Are you certain of that?"</p>
+
+<p>"I know only what she says."</p>
+
+<p>Duvall looked at him curiously. "What is the
+news she has brought you?"</p>
+
+<p>"A message from the scoundrels who have
+stolen the child. They want a hundred thousand
+dollars, to return him."</p>
+
+<p>"And she brought you that message?"</p>
+
+<p>"Yes." The banker regarded his questioner
+uneasily.</p>
+
+<p><span class='pagenum'><a name="Page_105" id="Page_105">[105]</a></span>"Does it not seem rather singular, Mr. Stapleton,
+that a member of the Paris police should
+come to you with a message from the kidnappers?"</p>
+
+<p>Mr. Stapleton frowned. "I had not considered
+that aspect of the case, Mr. Duvall. I was&mdash;and
+am&mdash;too anxious to get my boy back, to care
+by whom these fellows deliver their terms."</p>
+
+<p>"What was the message, Mr. Stapleton?"</p>
+
+<p>"I am to drive along the road to Versailles
+tomorrow evening, leaving here at eight o'clock,
+and moving at the rate of twelve miles an hour.
+Somewhere on that road, an automobile in passing
+will signal me with a blue light. I am then
+to slow up and toss into the other machine a
+package containing one hundred thousand dollars.
+If I do this, and make no attempt to follow
+or capture the rascals, they agree to deliver the
+child here&mdash;at my house&mdash;by the time I return
+home."</p>
+
+<p>Duvall listened to Mr. Stapleton's words with
+growing interest. "They are a shrewd lot," he
+exclaimed. "They will get away in their machine,
+and have ample opportunity to examine the package
+to see that it contains the amount they demand.
+By signaling to confederates at any point<span class='pagenum'><a name="Page_106" id="Page_106">[106]</a></span>
+along the road, or in another automobile, they
+can advise them whether or not to return the
+child."</p>
+
+<p>"But how will they be able to do this, without
+running the risk of being caught?"</p>
+
+<p>"That is easy. They take the boy to Paris,
+employ a passerby&mdash;a man of their own class, no
+doubt&mdash;for a few francs, to deliver him at your
+door. To trace them, through that means, will
+be impossible. If you give them the money, the
+chances are that they will never be caught."</p>
+
+<p>"Nevertheless, I shall give it to them."</p>
+
+<p>"I expected that, Mr. Stapleton. I can understand
+your feelings. It is not right, of course,
+to submit to this blackmail; but no doubt, were I
+situated as you are, I would do the same thing.
+Still, it is a great pity."</p>
+
+<p>"Why?"</p>
+
+<p>"Because we have an excellent chance to capture
+these fellows."</p>
+
+<p>"And lose the boy!"</p>
+
+<p>"Yes, that might be true. Such men are apt
+to retaliate very promptly, and very severely.
+They have no pity. I wish I might handle the
+case to suit myself."</p>
+
+<p>"What would you do?"</p>
+
+<p><span class='pagenum'><a name="Page_107" id="Page_107">[107]</a></span>"I would arrange to follow you, in a fast car,
+keeping say five hundred feet in the rear. I
+should have several men, well armed, in the
+car. By watching carefully, with field glasses if
+necessary, I would observe the car which signaled
+you with the blue light. When this car
+passed me, I would follow, but make no move
+which would alarm the kidnappers until they had
+given the signal&mdash;whatever it is&mdash;that would ensure
+your boy being returned to you. Then I
+would close in on them, and arrest them."</p>
+
+<p>"Your plan, Mr. Duvall, is open to serious
+objections. Suppose these men, undoubtedly on
+the watch, observe that they are being followed.
+They will give no signal&mdash;and I will lose not only
+my child, but the one hundred thousand dollars
+as well. No, no, I want no interference in the
+matter whatever."</p>
+
+<p>Duvall remained a moment in silence. "Very
+well, Mr. Stapleton, I am under your orders, of
+course. But I dislike very much to see these
+fellows get away."</p>
+
+<p>"So do I; but there's no help for it."</p>
+
+<p>"If I can work out a plan for their capture,
+which will not involve the loss of the boy, you
+are willing, I take it, to let me go ahead?"</p>
+
+<p><span class='pagenum'><a name="Page_108" id="Page_108">[108]</a></span>"Yes; but I insist that you first submit the
+plan to me."</p>
+
+<p>"Very well. And now, another matter. This
+woman who brought the message to you is, you
+say, an agent of the police. Did she attempt to
+explain how she came by the message?"</p>
+
+<p>"Yes. She was forcibly abducted, last night,
+carried a long distance out into the country, and
+the instructions given her. She was brought back
+to Paris, blindfolded, tonight."</p>
+
+<p>"Mr. Stapleton, what would you say were I to
+tell you that less than an hour ago I saw this
+woman in the rooms of Alphonse Valentin, a man
+whom I suspect to be very deeply concerned in the
+kidnapping of your son?"</p>
+
+<p>Stapleton started. "Is it possible?" he said.
+"Have you any idea what she was doing
+there?"</p>
+
+<p>"No. They seemed on excellent terms, however.
+Of course, it is not impossible that an
+agent of the police might pose as a friend of one
+of the criminals, and thus obtain information.
+But it looks decidedly queer."</p>
+
+<p>"It does, indeed. Still, as I said before, if I
+get my boy back, I shall be satisfied." He took
+a turn about the room, chewing nervously upon<span class='pagenum'><a name="Page_109" id="Page_109">[109]</a></span>
+his long black cigar. "Now, Mr. Duvall, what
+is your plan to capture these fellows?"</p>
+
+<p>Duvall sat in deep thought for sometime.
+"It is not an easy matter, Mr. Stapleton, but
+there is one way which promises success, and that,
+too, without interfering with your arrangements
+to recover your boy."</p>
+
+<p>"What is it?"</p>
+
+<p>"This. It is necessary for us, in some way,
+to identify the car which gives you the signal of
+the blue light. It will pass close to you, at a
+moderate speed. I want you to mark that car,
+so that it may be recognized at once."</p>
+
+<p>"How can I do that?"</p>
+
+<p>"I will place in the bottom of your machine
+a small device, consisting of a rubber bulb,
+equipped with a small nozzle, projecting through
+a hole in the body of the car. The bulb will be
+filled with indelible red stain. When you stand
+up, to toss the package of money to the kidnappers,
+you must press this bulb with your foot.
+The two cars will then be side by side. The
+pressure on the bulb will discharge a blast of the
+red stain against the body and wheels of the car
+opposite you. It will then be a simple matter to
+identify it."</p>
+
+<p><span class='pagenum'><a name="Page_110" id="Page_110">[110]</a></span>"Yes&mdash;yes. I see that. But what then?"</p>
+
+<p>"The car, in passing you, will be headed for
+Paris. Undoubtedly it is the intention of these
+fellows to enter the city. I shall station myself
+at the Porte de Versailles, and I will arrange to
+have other men, members of the detective bureau,
+stationed at the neighboring gates in the
+fortifications. All cars entering the city will be
+momentarily halted. The one which bears upon
+its body or wheels the red stain will be seized,
+its occupants arrested."</p>
+
+<p>"But suppose they have not yet notified their
+confederates to return the boy to me?"</p>
+
+<p>"In that event, I feel certain that the child
+will be found in the automobile with them. Look
+at the thing as you would, were you in their
+place. They are forced to act with great quickness.
+Were they to signal, by lights or otherwise,
+to persons along the road, they could hardly hope
+to get the boy to your house before you yourself
+return there. They know you will return home
+immediately at your best speed as soon as you
+have delivered the money to them. What more
+likely, then, that they will have the boy with
+them in the car, will drive to some prearranged
+point in Paris, and deliver him to the person who<span class='pagenum'><a name="Page_111" id="Page_111">[111]</a></span>
+will bring him to your house? That would seem,
+to my mind, their most probable plan."</p>
+
+<p>"And if not&mdash;if the child is not with them?"</p>
+
+<p>"Then there are but two courses open to them.
+The first is to signal, by lights or otherwise, to
+their confederates, before they enter Paris. If
+they do this, the boy will be returned to you,
+and we will capture the men as well. The only
+other alternative, of course, is for them to notify
+their confederates after they enter Paris."</p>
+
+<p>"But, if you arrest him at the barrier, they
+cannot do that, and my boy will not be sent
+back."</p>
+
+<p>"That is true; but I do not think they will
+wait to notify their confederates until after they
+enter Paris."</p>
+
+<p>"Why not, Mr. Duvall?"</p>
+
+<p>"First, because of the danger of being observed,
+in the crowded streets of the city. Secondly,
+because I do not think the child is in Paris
+at all. The woman who brought you the message
+from the kidnappers, I understand, saw the
+child at a point some distance in the country.
+It seems unlikely that these men would run the
+risk of conveying the child into the city, in broad
+daylight. By having the boy with them in the<span class='pagenum'><a name="Page_112" id="Page_112">[112]</a></span>
+car, they avoid all danger of signaling anybody.
+They merely inspect the package of money, run
+into Paris, fully believing themselves for the time
+being safe, drop the child at a convenient point,
+divide the plunder, and scatter to their respective
+hiding places. Criminals of this sort know perfectly
+well that they are far safer, hiding in a
+big city, than fleeing through the country in an
+automobile. I feel scarcely any doubt that they
+have the child with them."</p>
+
+<p>"But if he is still in the country, and they wait
+until after they are in Paris before notifying
+their confederates?"</p>
+
+<p>"Then the latter are obliged to journey a long
+distance out into the country, get the child, and
+bring him back to your house. That would require
+a considerable period. They could not possibly
+do it before you return home."</p>
+
+<p>Mr. Stapleton considered the matter for a long
+time in silence. "Your arguments seem sound,
+Mr. Duvall," he presently observed. "Like yourself,
+I am anxious to capture these fellows. It
+makes my blood boil, to think of their getting
+away. Of course, your deductions may be
+wrong."</p>
+
+<p><span class='pagenum'><a name="Page_113" id="Page_113">[113]</a></span>"Then at least we will get the perpetrators of
+the crime, and it is most likely that one of them,
+at least, may be persuaded to turn state's evidence,
+and disclose the whereabouts of your
+son."</p>
+
+<p>Mr. Stapleton pondered the matter with great
+care. Evidently he feared any course of action
+which did not insure the return of the child.</p>
+
+<p>"It seems to me, Mr. Stapleton," the detective
+went on, "that you owe it to the public to
+let me make this effort to capture these fellows.
+It is a grave danger to the community, to have
+such rogues at large. Let me try my plan. Even
+if it fails, you are no worse off than you are
+now. The attempt cannot in any way be traced
+to you."</p>
+
+<p>"Very well," said the banker, nervously. "It
+is a chance&mdash;that's all. However, since it seems
+to involve no breach of faith on my part, I am
+willing to take it."</p>
+
+<p>"Good! I will bring the device I spoke of to
+your house tomorrow, and attach it to your car.
+Your man Fran&ccedil;ois will drive you, I presume."</p>
+
+<p>"Yes."</p>
+
+<p>"You trust him?"</p>
+
+<p><span class='pagenum'><a name="Page_114" id="Page_114">[114]</a></span>"I have no reasons for not doing so. And besides
+he will know nothing of the affair. His
+part will be merely to drive the car, as I direct
+him."</p>
+
+<p>Duvall thought for a moment. "You will not,
+of course, give him his instructions until the last
+moment&mdash;just before you start."</p>
+
+<p>"No. That will be best, I think."</p>
+
+<p>"Undoubtedly. And to avoid any possible interference,
+I think I had better not attach the
+identifying device of which I have spoken to your
+car until late tomorrow afternoon, immediately
+before you set out. Then, if by any chance your
+chauffeur is in this plot, he will have no opportunity
+to give a warning."</p>
+
+<p>"Very well. I think, however, that your precautions
+are needless. There has been nothing
+whatever brought out to connect Fran&ccedil;ois with
+this matter."</p>
+
+<p>"I know; but it is well to be careful. You
+will leave here tomorrow evening, at eight
+o'clock?"</p>
+
+<p>"Yes. Promptly at eight."</p>
+
+<p>"You might do well to have someone with
+you, some member of the police, perhaps."</p>
+
+<p>"The instructions expressly forbid it."</p>
+
+<p><span class='pagenum'><a name="Page_115" id="Page_115">[115]</a></span>"Ah&mdash;I see. These fellows are shrewd." He
+took up his hat. "Until tomorrow then. Good
+night."</p>
+
+<p>"Good night."</p>

+<h2>CHAPTER VIII</h2>
+
+<p class="cap extraspacetop">AT the same hour that Richard Duvall was
+arranging with Mr. Stapleton his plan for
+the capture of the kidnappers the following
+day, Grace was closeted with Monsieur
+Lefevre, the Prefect of Police, in the latter's
+library, going over the affair in all its details.
+The Prefect was speaking, ticking off on his fingers
+the points in the case as he proceeded.</p>
+
+<p>"First, we have the impossible story of the
+nurse, Mary Lanahan. She seems to be telling
+the truth; yet I believe she is lying. In my opinion,
+she is deeply concerned in the whole matter."</p>
+
+<p>"But what about the attempt to poison her?"</p>
+
+<p>"It is highly probable that she poisoned herself,
+taking a slight dose only. This would divert
+suspicion from her."</p>
+
+<p>"I see."</p>
+
+<p>"Then we have the case of Alphonse Valentin,
+and the mysterious gold-tipped cigarettes. Your<span class='pagenum'><a name="Page_117" id="Page_117">[117]</a></span>
+husband, Monsieur Duvall, I am informed, has
+found one of these cigarettes, partly smoked, on
+the grass at the scene of the crime. This might
+indicate that Valentin was there, with her, on
+some occasion, but not necessarily on the day the
+kidnapping occurred. It might readily have been
+the day before&mdash;or the week before, for that
+matter."</p>
+
+<p>"I thought of that," remarked Grace, quietly.
+"It seems to me that Richard attached too much
+importance to the matter."</p>
+
+<p>"That remains to be seen. Now, supposing
+Valentin to be concerned, with the nurse, in the
+plot. He of course does not think, at the start,
+that the possession of the cigarettes would involve
+him in the affair, because he does not know
+that Monsieur Duvall has found the one in the
+grass. Your husband, however, asks Mary Lanahan
+what kind of cigarettes Valentin smokes. She
+at once becomes suspicious, and at the first opportunity
+warns Valentin, by letter, to destroy them.
+That shows clearly that they are working together."</p>
+
+<p>"Undoubtedly. But meanwhile the cigarettes
+are stolen from Valentin's room by a man with
+a dark beard, who subsequently enters Mr. Stapleton's<span class='pagenum'><a name="Page_118" id="Page_118">[118]</a></span>
+house. For that, I confess, I can find no
+explanation."</p>
+
+<p>"Nor I. The destruction of the cigarettes
+could be of no importance to anyone, except to
+the kidnappers themselves. It is of course possible
+that someone else in Mr. Stapleton's house&mdash;Fran&ccedil;ois,
+for instance&mdash;is concerned in the
+plot."</p>
+
+<p>"But the man who took the cigarettes had a
+black beard, while Fran&ccedil;ois is smooth shaven."</p>
+
+<p>"I know. But it might have been a disguise."</p>
+
+<p>"I do not think so. The man I saw was taller
+than Fran&ccedil;ois, and not so heavily built."</p>
+
+<p>The Prefect considered the matter for a moment.
+"You are certain that he entered the
+Stapleton's house?"</p>
+
+<p>"Absolutely certain. I saw the gate close behind
+him."</p>
+
+<p>"Then I can only say that, so far, the matter
+is inexplicable. Now let us come back to Valentin.
+He claims to be working to capture the
+kidnappers&mdash;in order to clear the nurse, whom
+he loves."</p>
+
+<p>"That is as I understand it."</p>
+
+<p>"He denies that he smokes, yet offers no explanation<span class='pagenum'><a name="Page_119" id="Page_119">[119]</a></span>
+of the presence of the cigarettes in his
+room."</p>
+
+<p>"None. Further, someone sends a note to
+Valentin, advising him that the writer is suspicious
+of Fran&ccedil;ois&mdash;suggesting that he watch
+him. Can this mean that Fran&ccedil;ois is in the plot,
+and they fear he may be weakening&mdash;preparing
+to turn against them?"</p>
+
+<p>"It certainly looks that way."</p>
+
+<p>"I wish I could see one of these famous cigarettes."</p>
+
+<p>Grace laughed suddenly. "Why," she exclaimed,
+"I have one in my pocketbook. I had
+quite forgotten it." She opened her purse and
+took out the slender white cylinder.</p>
+
+<p>Lefevre examined the thing closely. "An
+Egyptian cigarette of American make," he mused.
+"Expensive, here in Paris, and rarely used, except
+by Americans."</p>
+
+<p>"That is true; yet I understand that this man
+Valentin has lived a great deal in America."</p>
+
+<p>For a moment the Prefect did not reply. Then
+a puzzled look crossed his face. "This is a
+woman's cigarette," he exclaimed. "No man
+would smoke such a thing." He brought his
+hand down sharply upon his knee. "My girl,<span class='pagenum'><a name="Page_120" id="Page_120">[120]</a></span>
+it is not impossible that the child was stolen not
+by a man at all, but by a woman."</p>
+
+<p>"A woman, apparently, that both Valentin and
+the nurse are trying to shield."</p>
+
+<p>The Prefect sat for a moment buried in
+thought. Then he glanced at Grace keenly. "It
+seems to me," he remarked, in a quiet tone, "that
+we should endeavor to determine whether or not
+Mrs. Stapleton is in the habit of using cigarettes."</p>
+
+<p>"Mrs. Stapleton!" gasped Grace, in amazement.</p>
+
+<p>"Yes. I confess the idea is a new one, to me;
+but it may prove of interest."</p>
+
+<p>"But why should the boy's mother wish to
+kidnap him?"</p>
+
+<p>"I do not know. There is but one point of
+significance. During the past week my men have,
+naturally, questioned Mrs. Stapleton closely as
+to her movements during the past two or three
+months. They did this, to determine, if possible,
+whether the criminals were of Paris, or from
+some other place, where Mrs. Stapleton may have
+been, with the child, during the past winter. You
+know these fellows work in bands, and have their
+regular field of operations."</p>
+
+<p>"I see. And where had she been?"</p>
+
+<p><span class='pagenum'><a name="Page_121" id="Page_121">[121]</a></span>"Monte Carlo!" The Prefect uttered the two
+words significantly.</p>
+
+<p>Grace was quick to grasp his meaning.</p>
+
+<p>"Then you mean that possibly Mrs. Stapleton
+may have lost large sums at the gambling tables,
+and, fearing to tell her husband of her losses,
+has enlisted the services of the nurse, and of her
+friend Valentin, and spirited the child away for a
+few weeks, in order to get the sum of one hundred
+thousand dollars from her husband without
+his knowledge?"</p>
+
+<p>"It is by no means impossible. I would recommend
+that you investigate the matter thoroughly.
+If we find that Mrs. Stapleton uses gold-tipped
+cigarettes of this variety, it may go far toward
+a solution of the whole affair."</p>
+
+<p>Grace, remembering Mrs. Stapleton's grief-stricken
+appearance, felt that the clue was a very
+slender one, but determined to follow it up, nevertheless.</p>
+
+<p>"Now," went on the Prefect, "we come to the
+sudden and most unexpected appearance of Valentin,
+clinging to the rear of the automobile that
+brought you back to Paris tonight."</p>
+
+<p>"As I have told you, he claims to have clambered
+into Mr. Stapleton's car."</p>
+
+<p><span class='pagenum'><a name="Page_122" id="Page_122">[122]</a></span>"Driven by Fran&ccedil;ois?"</p>
+
+<p>"Yes."</p>
+
+<p>"And you say the man who drove the car had
+a black beard&mdash;the same man, in fact, who broke
+into Valentin's room and stole the cigarettes?"</p>
+
+<p>"Yes."</p>
+
+<p>"Then either Valentin is lying, or the man with
+the black beard is Fran&ccedil;ois. Let us look at his
+story from both sides. If he is telling the truth,
+then Fran&ccedil;ois is one of the kidnappers."</p>
+
+<p>"So it would seem. You are having him
+watched, you say?"</p>
+
+<p>"Yes. My men report that he did leave the
+house, in Mr. Stapleton's automobile tonight, at
+about nine o'clock. That would seem to agree
+with Valentin's story. They also report that he
+returned about eleven, alone."</p>
+
+<p>"They did not follow him?"</p>
+
+<p>"No. It is impossible to do so, in another car,
+without arousing his suspicion, and putting him
+on his guard. We do not wish him to know that
+he is being watched."</p>
+
+<p>"But Mr. Stapleton must know where he has
+been&mdash;why the car was out."</p>
+
+<p>"Yes. We have questioned him. He says the
+man reported that the gasolene tank was leaking,<span class='pagenum'><a name="Page_123" id="Page_123">[123]</a></span>
+and that he ordered him to have it repaired
+at once."</p>
+
+<p>"And was it repaired?"</p>
+
+<p>The Prefect smiled. "Yes. The car was at
+a garage in the Boulevard St. Michel from half
+past nine until half past ten."</p>
+
+<p>Grace fell back, astonished. "Then Valentin
+is lying!" she cried.</p>
+
+<p>"So it seems; unless, of course, Fran&ccedil;ois took
+out another car from the garage, while his own
+was being fixed."</p>
+
+<p>"They would know that at the garage."</p>
+
+<p>"They deny it. But these fellows all hang together.
+They would think nothing of protecting
+a brother chauffeur, in the matter of a little joy
+ride."</p>
+
+<p>"Valentin says nothing about this, in his
+story."</p>
+
+<p>"He may have omitted it, as an unimportant
+detail. I mean that he may have slipped into the
+second car, as he did into the first, without being
+observed. It was dark of course. He may not
+have thought it necessary to mention it. All this,
+of course, is on the assumption that he is telling
+the truth. Now let us say that he is lying&mdash;that
+the man with the black beard is not Fran&ccedil;ois,<span class='pagenum'><a name="Page_124" id="Page_124">[124]</a></span>
+but someone else concerned, with Valentin in the
+plot. What is the purpose of his tale?"</p>
+
+<p>"I cannot imagine. Can you, Monsieur?"</p>
+
+<p>"No, not immediately. The first contradiction,
+of course, is this. If Valentin and the man
+with the black beard are working together, why
+should the latter have broken into his room to
+get the cigarettes?"</p>
+
+<p>"There seems no sense to it."</p>
+
+<p>"Yet he may have realized the danger of the
+cigarettes being in Valentin's possession, and instead
+of trying to warn him simply came and took
+them away. It is not a particularly plausible
+explanation; but let us admit it, for the moment,
+in order to get ahead with our reasoning. Suppose
+Valentin, the man with the black beard, and
+Mary Lanahan, the nurse, to be all working together,
+either with Mrs. Stapleton, or with outside
+parties. They have the child safely hidden.
+They abduct you, and send the message to Mr.
+Stapleton through you. They do not trust you,
+knowing, no doubt, that you are an agent of my
+office. They send Valentin along, on the back
+of the machine, to pretend to be an enemy of
+theirs trying, like yourself, to recover the child.
+He thus gets into your confidence. He advises<span class='pagenum'><a name="Page_125" id="Page_125">[125]</a></span>
+you to report your message from the kidnappers
+to Mr. Stapleton at once. He questions you, and
+learns that you do not know the location of the
+house where the child is hidden. He then offers
+to show you as nearly as he can where the house
+is located. If he is in league with the kidnappers,
+he will take you, and the men whom tomorrow I
+shall send with you, to some location miles removed
+from the actual point where the child is
+concealed, and you will waste the day in a useless
+search. Decidedly it would be a clever move
+on their part."</p>
+
+<p>"It certainly would."</p>
+
+<p>"Further, you told this fellow that you had a
+plan to capture the scoundrels. You are to acquaint
+him with that plan, tomorrow afternoon.
+If you do so, he will no doubt get to the telephone
+on some pretext and warn his comrades of what
+you intend to do. I strongly recommend that
+you put no faith in the fellow whatever."</p>
+
+<p>"Still, you would advise trying to locate the
+house, as he suggests?"</p>
+
+<p>"Yes, we may be wrong about him. We must
+leave no stone unturned. And now we come to
+your interview with Mr. Stapleton. You gave
+him the message, of course. What did he say?"</p>
+
+<p><span class='pagenum'><a name="Page_126" id="Page_126">[126]</a></span>"He said that he intended to carry out the instructions
+I gave him to the letter&mdash;pay these
+fellows their money, and get back the boy."</p>
+
+<p>Monsieur Lefevre uttered an exclamation of
+anger. "Sacr&eacute;! He must not do that! The
+stupid fellow! He will spoil everything!"</p>
+
+<p>Grace laughed quietly to herself. "Hardly
+stupid, Monsieur! The poor man is half mad
+over the boy's loss. He will do anything, to get
+him back. I can scarcely blame him."</p>
+
+<p>The Prefect held out his hand. "I beg your
+pardon, my child. You are right. It is perhaps
+but natural for him to feel as he does. But there
+are other things at stake, than the recovery of
+the child. For Monsieur Stapleton to pay over
+this huge sum to these criminals, and then to
+allow them to escape, is not only a grave reflection
+upon the efficiency of the Paris police, but is
+an injustice to the public as well. If these men
+are successful in this attempt, they will make
+others. Other children will be stolen. I cannot
+permit it. It must be prevented at all costs.
+These men must be brought to justice."</p>
+
+<p>"How can you prevent it, Monsieur? Mr.
+Stapleton is determined."</p>
+
+<p>"That, my child, is the question. I cannot stop<span class='pagenum'><a name="Page_127" id="Page_127">[127]</a></span>
+Monsieur Stapleton if he wishes to drive out
+the road to Versailles and toss a hundred thousand
+dollars into the first automobile that passes
+him, showing a blue light." He rose and began
+to walk up and down the room.</p>
+
+<p>"I have a plan, Monsieur," said Grace, quietly.</p>
+
+<p>"What is it, my child?" The Prefect regarded
+her with an indulgent smile. He was very fond
+of Grace. He regretted that he had been unable
+to secure the services of her husband in this case.
+He knew, from past experience, her cleverness;
+but he did not believe that in a matter of this
+sort she would be able to outwit men who were
+probably among the shrewdest criminals in
+Paris.</p>
+
+<p>"First," said Grace, "we will have the location
+pointed out to us by Valentin thoroughly
+searched."</p>
+
+<p>"Assuredly! It will, however, probably result
+in nothing. Even if Valentin is telling the truth,
+these fellows will beyond question have moved
+the child before now to prepare for the work of
+tomorrow evening."</p>
+
+<p>"Possibly. At any rate, we will try. After
+that, I shall want Valentin to drive a motor car
+for me. He is an accomplished chauffeur."</p>
+
+<p><span class='pagenum'><a name="Page_128" id="Page_128">[128]</a></span>"You will take him into your confidence, then?"
+asked the Prefect, in some alarm.</p>
+
+<p>"No. I shall tell him nothing, except that he
+is to drive the car, and where."</p>
+
+<p>"Very well. But be careful. What next?"</p>
+
+<p>Grace leaned over and spoke to the Prefect in
+low tones for several minutes. He listened to
+what she said, occasionally smiling, and nodding
+his head. Presently he brought his hand down
+sharply upon the table. "Bravo!" he exclaimed.
+"You were born to be a detective. We will get
+the kidnappers, the money, and in all probability
+the child as well. I congratulate you!"</p>
+
+<p>"You think it will work, then?"</p>
+
+<p>"I do not see how it can fail. It is an inspiration.
+I shall certainly feel very well satisfied
+indeed, if I can return to Monsieur Stapleton
+both his child and his money, and at the same
+time place the kidnappers behind the bars. I
+could never permit it to be said that the police
+of Paris would knowingly allow a desperate band
+of criminals to get away with half a million of
+francs without lifting a hand to prevent it." He
+rose and glanced at his watch. "Come, my
+child. It is after midnight. You have had a long
+and exciting day. You had better get some rest."</p>
+
+<p><span class='pagenum'><a name="Page_129" id="Page_129">[129]</a></span>Grace rose. "Richard seemed awfully puzzled
+when he saw me."</p>
+
+<p>"Did he?" The Prefect laughed mischievously.
+"Really it is a great joke upon him. To
+be within a step of his own wife, and not to know
+her!"</p>
+
+<p>Grace seemed scarcely to appreciate the humor
+of the situation. "I think it's a shame," she said,
+"Poor Richard. He'll never forgive me. I really
+think I ought to tell him."</p>
+
+<p>Monsieur Lefevre shook his head. "If you
+do that, my dear child, everything will be spoiled.
+He will insist upon your dropping the case at
+once, and that would certainly not be fair to me."</p>
+
+<p>"But, Monsieur, after all, you really do not
+need me, with all the clever men you have upon
+your staff."</p>
+
+<p>"Who knows? Perhaps you may succeed,
+where they will fail. I have great faith in the
+intuition of a woman. And already you have
+advanced the case further in forty-eight hours
+than my men have done in ten days. It was a
+chance, I will admit, that these rascals should
+have chosen you to deliver their demands to
+Monsieur Stapleton. I confess I do not understand
+their reasons for doing so. They must<span class='pagenum'><a name="Page_130" id="Page_130">[130]</a></span>
+have known that besides telling your story to him,
+you would also tell it to me. It may have been
+sheer bravado on their part&mdash;it is a characteristic,
+I have noted, in many criminals. They seem to
+glory in defying the police. These fellows, no
+doubt, think that they have matters so arranged
+that capture is impossible. I think we shall give
+them a little surprise."</p>
+
+<p>He turned to the door, and held it open, allowing
+Grace to pass into the hall. "Good night,
+my child," he called out to her, as she began to
+ascend the stairs. "I think I will smoke one more
+cigar."</p>
+
+<p>As for Grace, she lay awake a long time, thinking
+of Richard, of their home in the country, of
+the happy hours they had spent there&mdash;before this
+unexpected interruption to their honeymoon. It
+seemed very queer to her, to be lying there, alone.
+She had not gotten used to it. And somewhere,
+in this big city, Richard was also sleeping&mdash;and
+she not with him! The excitement of the affair
+was beginning to die out. The meeting with Richard
+on the boat, which she had planned when she
+set out from home, had not materialized. She had
+postponed this meeting, in her thoughts, until his
+arrival in Paris, and now&mdash;he had come, and still<span class='pagenum'><a name="Page_131" id="Page_131">[131]</a></span>
+she had not been able so much as to touch his
+hand. She finally went to sleep, devoutly praying
+that tomorrow, and the capture of the kidnappers,
+would mark the end of their needless and
+cruel separation.</p>

+<h2>CHAPTER IX</h2>
+
+<p class="cap extraspacetop">PROMPTLY at eight o'clock the next evening
+Mr. John Stapleton left his house in
+the Avenue Kleber, in a big French touring
+car, with Fran&ccedil;ois at the wheel.</p>
+
+<p>The car presented no points of peculiarity,
+being like a thousand others to be seen any evening
+upon the streets of Paris. It was of large
+size, high powered, and painted a green so dark
+as to be almost black.</p>
+
+<p>Mr. Stapleton sat in the tonneau, wearing a
+dark blue serge suit, and a Panama hat. In his
+left hand he clutched a small package, about the
+size of a cigar box. In the package were banknotes
+amounting to one hundred thousand dollars.</p>
+
+<p>Close beside his right foot lay a rubber bulb,
+from which a short pipe extended through a hole
+bored in the side of the car. The end of the pipe
+held a small brass nozzle. It projected but a
+short distance beyond the body of the car, and<span class='pagenum'><a name="Page_133" id="Page_133">[133]</a></span>
+in the dim light of early evening was quite invisible.</p>
+
+<p>Mr. Stapleton told his chauffeur to drive out
+the road toward Versailles. "I feel like getting
+some fresh air," he added. "It's rather warm,
+tonight." Inwardly he was burning up with excitement.</p>
+
+<p>From Paris to Versailles is a matter of some
+fourteen miles. Mr. Stapleton's car proceeded
+slowly. He wanted to run no chances of missing
+the car with the blue light.</p>
+
+<p>At the Porte de Versailles he paused long
+enough to see Richard Duvall, standing in the
+shadow of the gateway. Then he passed outside
+of Paris.</p>
+
+<p>There were many automobiles and other vehicles
+on the road. The evening was a pleasant
+one, and all Paris seemed out taking the air. The
+majority of the vehicles were coming toward the
+city. He observed a car, some distance behind
+him, containing a single occupant, a man of middle
+age, but paid no attention to it. His eyes
+were strained to detect in the cars approaching
+him some evidence of the signal light which was
+to rouse him to sudden action.</p>
+
+<p>He noticed that Fran&ccedil;ois, like himself, was<span class='pagenum'><a name="Page_134" id="Page_134">[134]</a></span>
+carefully scrutinizing each car as it approached
+them. He wondered if the chauffeur could have
+any idea of the purpose of his expedition; but
+presently dismissed the thought as entirely unlikely,
+and devoted himself to the passing cars.</p>
+
+<p>He had proceeded perhaps four or five miles
+beyond the fortifications, when he saw a large
+car approaching slowly from the direction of
+Versailles. It contained but two persons, the
+chauffeur, and a heavily veiled woman.</p>
+
+<p>The chauffeur, who was keenly observing the
+machine in which Mr. Stapleton sat, began to
+swerve to the right side of the road, so as to
+pass as closely to the banker's car as possible. At
+the same moment there showed through the gathering
+darkness a brilliant spot of blue light in the
+tonneau where sat the woman.</p>
+
+<p>Mr. Stapleton was on his feet in an instant.
+The two cars approached each other rapidly. It
+was necessary for him to act with great quickness.
+He shifted the package containing the money
+from his left hand to his right, and a moment
+later had tossed it lightly into the other car.</p>
+
+<p>He saw at once that it landed safely within, and
+at the same instant he pressed his foot down hard
+upon the rubber bulb. In a moment the car with<span class='pagenum'><a name="Page_135" id="Page_135">[135]</a></span>
+the blue light had swept past, and was disappearing
+rapidly in the direction of Paris.</p>
+
+<p>Mr. Stapleton leaned forward and addressed
+Fran&ccedil;ois in a voice which quivered with excitement.
+"Drive home at once," he commanded.</p>
+
+<p>In a moment he was following the first car
+toward the city.</p>
+
+<p>He did not notice, as he swept down the darkening
+road, the car which had been following
+him all the way from Paris. It continued on its
+way toward Versailles. In it were two people.
+At the wheel sat a man who bore, in the semi-darkness,
+a striking resemblance to Fran&ccedil;ois, Mr.
+Stapleton's chauffeur, while in the rear sat a
+figure, in dark suit and Panama hat, which seemed
+for all the world like that of the banker himself.
+Had a casual observer not seen Mr. Stapleton
+turn back toward Paris, he would have concluded
+that he was still on his way toward Versailles.</p>
+
+<p>The occupants of this second car also appeared
+to be keenly watching the various automobiles
+which passed them, as though expecting some signal,
+some recognition; yet, in spite of their eager
+and expectant glances, they seemed doomed to
+disappointment.</p>
+
+<p>At last Versailles was reached. The elderly<span class='pagenum'><a name="Page_136" id="Page_136">[136]</a></span>
+man in the tonneau gave a short command, his
+chauffeur turned the car about, and they began to
+return to Paris. Nothing further whatever happened
+on the Versailles road.</p>
+
+<p>Meanwhile, Richard Duvall, at the Porte de
+Versailles, was carefully scrutinizing the various
+incoming machines that passed the gate and entered
+the city. With a brilliant electric searchlight
+he examined their bodies and wheels, looking
+always for the telltale red stains which
+would identify the kidnappers' car. Beside him
+stood Vernet, one of the Prefect's assistants, with
+whom Duvall had become well acquainted during
+his former stay in Paris.</p>
+
+<p>"Well, Monsieur Duvall," remarked the latter,
+"a most ingenious plan&mdash;this of yours. I wonder
+if it will be successful?"</p>
+
+<p>"I feel sure of it."</p>
+
+<p>"I hope you are right." He looked at his
+watch. "Half past eight. About time, I should
+think, from what you tell me. Here is a big fellow,
+now. A Pasquet, by her looks. Six-cylinder,
+too."</p>
+
+<p>Duvall glanced at the oncoming car. A wagon
+which preceded it was just passing the gates. The
+big Pasquet slowed up, and almost stopped.</p>
+
+<p><span class='pagenum'><a name="Page_137" id="Page_137">[137]</a></span>The detective threw the rays of his searchlight
+on the body of the car, then started back with an
+exclamation. From one end to the other, the
+dark green finish of the sides and wheels was
+spattered and streaked with bright red paint.
+Dust had settled in it, in places, especially on the
+wheels; but above, on the doors, it was clear and
+unmistakable.</p>
+
+<p>"Vernet," he shouted, excitedly, "it is the one!
+Quick! Don't let them get away."</p>
+
+<p>Vernet stepped up to the quivering motor. At
+the wheel sat a young man, quite composed. In
+the tonneau, a veiled woman reclined at ease. In
+her hands she held a brown paper package.</p>
+
+<p>She leaned toward Vernet, and spoke a single
+word to him. Duvall did not hear what it was;
+but its effect upon the Prefect's man was instantaneous&mdash;electrical.
+He stepped back and raised
+his hat. "Pardon, Madame," he said, and the
+Pasquet rolled through the gate and into the
+streets of Paris unmolested.</p>
+
+<p>Duvall had sprung forward, and, as he did so,
+swept the occupants of the car with his electric
+searchlight. Suddenly he drew back in amazement,
+just as Vernet allowed the car to pass on.
+He could scarcely believe that what he saw was<span class='pagenum'><a name="Page_138" id="Page_138">[138]</a></span>
+a reality. There was the big black car, its body
+and wheels plentifully bespattered with the identifying
+red stain&mdash;and there, at the wheel, sat
+Alphonse Valentin, while the veiled woman in the
+rear was&mdash;Grace!</p>
+
+<p>He did not know it was Grace&mdash;he did know
+that it was the woman who had been with Valentin
+in his room, who had brought the message from
+the kidnappers to Mr. Stapleton, who, in some
+far off and intangible way, reminded him of
+Grace.</p>
+
+<p>There she sat, in her hand the package containing
+Mr. Stapleton's money&mdash;and Vernet doffed
+his cap to her, and permitted her to go on! Was
+this woman, then, hoodwinking even the police?</p>
+
+<p>He sprang to Vernet's side. "Stop them!" he
+cried, in a hoarse voice. "They are the ones I
+am after."</p>
+
+<p>Vernet shook his head. "Impossible, Monsieur.
+They are given safe conduct by Monsieur
+the Prefect himself."</p>
+
+<p>"But&mdash;they are thieves&mdash;kidnappers!"</p>
+
+<p>Vernet shrugged his shoulders. "It may be so,
+Monsieur Duvall; but my orders are to let them
+pass."</p>
+
+<p>The detective ground his teeth, helpless. His<span class='pagenum'><a name="Page_139" id="Page_139">[139]</a></span>
+scheme for identifying the criminals had worked
+perfectly. He had found them, only to see both
+them and Mr. Stapleton's hundred thousand dollars
+as well slip quietly through his fingers. He
+cursed the whole police force of Paris roundly,
+in his anger.</p>
+
+<p>The arrival of another car distracted his attention.
+It was Mr. Stapleton, hurrying home,
+in the hope of finding his boy. Duvall did not
+stop him. The banker was evidently thinking of
+nothing but his lost son.</p>
+
+<p>Several other cars passed. Duvall had no
+interest in them. He was about to turn away,
+with the intention of hunting up Mr. Stapleton
+and learning whether or not the boy had been
+returned to him, when he heard a familiar voice
+calling him by name. He turned. It was Monsieur
+Lefevre, in a big dark green car.</p>
+
+<p>"Mon Dieu! Duvall!" the Prefect cried, in
+pretended surprise. "You here! In Paris! Or
+do my eyes deceive me?"</p>
+
+<p>The detective looked a bit sheepish. He realized
+that in not calling on his old friend before
+now, he had been guilty of an apparent rudeness
+which Monsieur Lefevre might justly resent.
+"Monsieur," he cried, "it is indeed I." He put<span class='pagenum'><a name="Page_140" id="Page_140">[140]</a></span>
+out his hand, and grasped that of his old chief
+warmly. "A little matter of business brought me
+to Paris. I have only just arrived."</p>
+
+<p>"Indeed." The Prefect's eyes twinkled. "I
+hope, my dear fellow, that your other engagements
+will permit you to come and see me before
+long."</p>
+
+<p>"I shall come this very evening, Monsieur. In
+fact, I have a matter of the utmost importance
+to discuss with you. Shall you be at liberty?"</p>
+
+<p>"In an hour, <i>mon ami</i>. Until then I have
+other things to occupy me. Come to the Prefecture
+in an hour. I shall be waiting for you. For
+the present, adieu." He called an order to his
+chauffeur, and drove rapidly off into the darkness.</p>
+
+<p>Duvall turned on his heel and began to look
+for a taxicab. "Good night, Vernet," he called
+out, as he went up the street.</p>
+
+<p>In half an hour, he had reached Mr. Stapleton's
+house. He found the unfortunate banker
+striding up and down his library in a towering
+rage. "The fellows have deceived me!" he cried.
+"They have not brought back my boy. Did you
+see anything of them? Tell me!" He grasped
+Duvall nervously by the arm.</p>
+
+<p><span class='pagenum'><a name="Page_141" id="Page_141">[141]</a></span>"The car into which you threw the package
+of money contained, besides the chauffeur, but
+one occupant, a woman, did it not?"</p>
+
+<p>"Yes&mdash;yes! Did you get her?"</p>
+
+<p>"No."</p>
+
+<p>"Why not? Did your scheme to identify the
+car fail to work?"</p>
+
+<p>"On the contrary, it worked perfectly. I
+stopped the car at the barrier. The woman in it
+had the package of money in her hand."</p>
+
+<p>"And you did not arrest her! In Heaven's
+name, why not?"</p>
+
+<p>"The police would not permit me to do so.
+The woman was the same one who brought you
+the message last night, the supposed agent of
+the police. They allowed her to pass the gates."</p>
+
+<p>"What?" the banker fairly shouted his question.
+"This is ridiculous! Is the woman a criminal,
+or is she a detective? She cannot be both,
+and if she is the latter why was she in that car,
+with my money in her hand?"</p>
+
+<p>"I do not know. But I mean to find out very
+shortly."</p>
+
+<p>"How? I'd like to know!"</p>
+
+<p>"I am going to see the Prefect of Police at
+once."</p>
+
+<p><span class='pagenum'><a name="Page_142" id="Page_142">[142]</a></span>Mr. Stapleton sank into a chair, and groaned.
+"I had hoped to have Jack with me by now.
+His poor mother is distracted. Isn't there anything,
+Mr. Duvall, that you can do?"</p>
+
+<p>"I hope to answer that question better, Mr.
+Stapleton, after I have seen Monsieur Lefevre.
+If this woman, and her companion, Valentin, are
+really the kidnappers, they are in Paris, and we
+shall be able to lay our hands on them without
+difficulty. If they are not, your money, at least
+is safe. I must leave you now; but as soon as
+I learn anything, I will report to you at once.
+Good night."</p>
+
+<p>He left the house, more mystified than he had
+ever been in his life. From the start, this case
+had apparently been one in which all the clues
+led to absurd contradictions, or else to nothing
+at all.</p>
+
+<p>In fifteen minutes he was at the Prefecture.</p>
+
+<p>Monsieur Lefevre sent out word that he would
+be occupied for a few moments, and the detective
+sat down as patiently as possible, to wait.</p>

+<h2>CHAPTER X</h2>
+
+<p class="cap extraspacetop">THE events of the Versailles road left Grace
+Duvall in a high state of good humor.
+The plan she had suggested had been a
+success&mdash;at least so far as her own part in it
+was concerned. How Monsieur Lefevre had
+fared, she did not yet know. She looked down
+at the brown paper package she held in her
+hand, and ordered Valentin to drive to the Prefecture.</p>
+
+<p>The day had been an eventful one. Immediately
+after breakfast Grace had gone to Mr.
+Stapleton's house and had a long interview with
+Mrs. Stapleton. That lady, apparently quite
+prostrated from worry and alarm over the fate
+of her son, received her in her boudoir, where she
+lay, a charming picture, upon a divan.</p>
+
+<p>Grace had no more than entered the room,
+when she detected the odor of cigarette smoke,
+faint but unmistakable. She glanced at the table
+which stood beside the divan upon which Mrs.<span class='pagenum'><a name="Page_144" id="Page_144">[144]</a></span>
+Stapleton lay. On it, a tiny porcelain ash receiver
+contained a fluffy mass of gray-white ashes, and
+the half smoked remains of a cigarette. The tip,
+partly covered by the ashes, was of gold.</p>
+
+<p>The girl engaged her hostess in a long conversation,
+quieting her fears, which seemed real
+enough, and predicting the early recovery of her
+boy. It was quite evident that Mrs. Stapleton
+was terribly nervous. No doubt this accounted
+for the cigarettes. Although Grace did not use
+them herself, she knew how their quieting effect
+on the nerves made them almost necessities, at
+times, to their devotees.</p>
+
+<p>Presently she observed that Mrs. Stapleton
+held within her left hand, concealed beneath the
+folds of her kimono, a small pasteboard box,
+a box of cigarettes. Grace determined upon a
+bold move.</p>
+
+<p>"May I have one of your cigarettes, Mrs.
+Stapleton?" she asked, in her sweetest manner.
+"I've forgotten to bring any with me&mdash;and&mdash;you
+know how it is."</p>
+
+<p>Mrs. Stapleton's features relaxed into something
+approaching a smile. She had been lying
+there wondering whether she dared offer one to
+Grace, and thus be able to sooth her own overstrained<span class='pagenum'><a name="Page_145" id="Page_145">[145]</a></span>
+nerves. She brought forth the box and
+extended it toward her visitor. Grace took one
+of the tiny cylinders and lit it. <i>It was of the
+same make as the one she had secured in Alphonse
+Valentin's room!</i></p>
+
+<p>She took her departure a little later, wondering
+greatly. The whole affair had begun to take
+on an air of baffling contradiction.</p>
+
+<p>She spent the rest of the morning, and most
+of the afternoon, searching the houses near
+the point on the road to Versailles indicated by
+Valentin. With her were three men from the
+Prefect's office&mdash;silent, able men, in plain clothes,
+who pretended to be keepers from the <i>Jardin
+des Plantes</i>, in search of a dangerous cobra, which
+was supposed to have escaped from its cage the
+night before.</p>
+
+<p>The terrified householders threw open their
+doors with unassumed alacrity. The suggestion
+of a deadly reptile lurking in their gardens was a
+veritable open sesame. Yet no traces of the missing
+boy were found, and, more remarkable still,
+Grace was unable to identify any of the many
+gardens as the one in which she had seen the
+child playing with the spaniel. This disappointed
+her greatly. She knew well that, if Valentin was<span class='pagenum'><a name="Page_146" id="Page_146">[146]</a></span>
+telling the truth, the garden was here; yet, although
+they visited every house within a quarter
+of a mile, they were unable to locate it. She remembered
+now that in her agitation, her eager
+examination of the child, she had not fixed upon
+her mind any salient point in the garden itself.
+All that she remembered was a bit of grass, a
+gravel walk, and the child playing with the dog.
+A dozen of the little enclosures presented similar
+features. She returned to the prefecture, baffled.</p>
+
+<p>"The fellow is undoubtedly lying," had been
+Monsieur Lefevre's comment. "He is trying to
+throw you off the track, in order to protect the
+nurse, and possibly Mrs. Stapleton as well. I
+should not be surprised to find that the boy's
+mother is the guilty person."</p>
+
+<p>Grace did not agree with him; so she said
+nothing. In spite of the fact that Mrs. Stapleton
+used cigarettes similar to those which seemed
+in some queer way to be at the bottom of the
+mystery, she had an intuitive feeling that the
+grief which the banker's wife showed was entirely
+real.</p>
+
+<p>At half past seven, Grace left the prefecture
+in a high-powered car, furnished by Monsieur
+Lefevre. Alphonse Valentin was at the wheel.<span class='pagenum'><a name="Page_147" id="Page_147">[147]</a></span>
+In her hand she held a pocket electric searchlight,
+across the front of which had been affixed a circular
+bit of blue glass.</p>
+
+<p>At ten minutes to eight she arrived at Versailles.
+She at once ordered Valentin to turn and
+drive back toward Paris at moderate speed. She
+did not take him into her confidence regarding
+what she proposed to do, but kept a keen watch
+for the car containing Mr. Stapleton.</p>
+
+<p>Her plan had worked. Mr. Stapleton, seeing
+her signal, had tossed her the package of money&mdash;she
+only hoped that the other part of her plan
+had been carried out with equal success.</p>
+
+<p>The other part of the plan had been this:
+Monsieur Lefevre, who in build and general appearance
+was not unlike Mr. Stapleton, was to
+follow the latter's car in a machine of the same
+make and general appearance. He was to be
+driven by a chauffeur made up to resemble Fran&ccedil;ois
+sufficiently to be mistaken for him in the
+dim light of early evening. He himself was to
+make such alterations in his appearance and dress
+as would enable him to pass, under a cursory
+examination, for Stapleton. In the bottom of the
+car two armed men lay concealed.</p>
+
+<p>When the car containing Mr. Stapleton turned<span class='pagenum'><a name="Page_148" id="Page_148">[148]</a></span>
+back toward Paris, after having unwittingly delivered
+the money to Grace, the Prefect would
+continue on toward Versailles. He would know
+that the car containing the kidnappers was still
+ahead of him; since, had it not been, it, instead of
+Grace's car, would have signaled Mr. Stapleton.</p>
+
+<p>Grace had started out from Versailles especially
+early, convinced that the kidnappers
+would not leave there until eight, at least. In
+this assumption she was correct. The car containing
+the kidnappers was, at that moment,
+creeping toward Paris some two miles in her
+rear, looking everywhere for Mr. Stapleton.</p>
+
+<p>The Prefect pursued his way toward Versailles
+in anxious expectancy. Each moment he thought
+to see the blue signal flash from the various cars
+which passed him. When it came, his men were
+to spring up, and at once bring the other car to
+a standstill by firing their guns, heavily charged
+with buckshot, at its wheels. A punctured tire,
+and the thing was done. His men, assisted by the
+chauffeur, would then overpower the occupants
+of the other car before they could realize what
+had happened. In it they hoped to find the
+child.</p>
+
+<p>The plan was well conceived; but unfortunately<span class='pagenum'><a name="Page_149" id="Page_149">[149]</a></span>
+it did not work. Whatever the reason, none of
+the cars which passed the Prefect on his way to
+Versailles displayed the telltale blue light. All
+seemed but peaceable automobilists, intent on
+reaching Paris and its restaurants as quickly as
+possible. Had his disguise been penetrated? He
+could not believe it. He returned to the Prefecture
+in great disgust, wondering in what way
+matters had gone wrong.</p>
+
+<p>Grace was waiting for him, an eager smile
+on her face. "Here is the money," she said,
+placing the package on his desk. "Did you get
+the men?"</p>
+
+<p>"No." The Prefect flung himself into a chair.
+"They did not signal."</p>
+
+<p>"But why, I wonder?" The failure of her
+plan was extremely annoying.</p>
+
+<p>"I can think of but one reason. There must
+have been some way in which these fellows knew
+the Stapleton car when they approached it&mdash;some
+signal, perhaps, that I was unable to give."</p>
+
+<p>"But no such signal was mentioned in the instructions
+I brought to Mr. Stapleton. He gave
+none, as we approached him."</p>
+
+<p>"Did you observe anything peculiar about the
+appearance of his car, anything that might have<span class='pagenum'><a name="Page_150" id="Page_150">[150]</a></span>
+served as a clue to enable these fellows to recognize
+it, even in the dark, with certainty?"</p>
+
+<p>Grace thought a moment, then her face fell.
+"There was one thing that I noticed as Mr.
+Stapleton's car came up to us; but I am afraid
+I failed to realize its significance at the time."</p>
+
+<p>"What was it?"</p>
+
+<p>"The electric headlight on the side nearest to
+me was working very badly. In fact, it seemed
+to be almost out. The other was burning brilliantly."</p>
+
+<p>The Prefect sprang to his feet. "Sacr&eacute;!" he
+exclaimed. "Of course. The thing is as plain as
+the nose on your face!"</p>
+
+<p>"But who&mdash;"</p>
+
+<p>"Fran&ccedil;ois! The fellow is in this thing up to
+his neck. <i>He</i> claims to have been asleep when
+the boy was stolen. <i>He</i> drives the car which
+brings you back, after your abduction. <i>He</i>, disguised,
+steals the box of cigarettes. <i>He</i> fixes the
+lights so that the kidnappers are advised, not
+only beyond any doubt that they are signaling
+the right car, but that all is safe&mdash;that Monsieur
+Stapleton has no detectives or members of the
+police hidden in his tonneau. The thing is perfectly
+clear. Believe me, my child, had there<span class='pagenum'><a name="Page_151" id="Page_151">[151]</a></span>
+been anyone in that car with Mr. Stapleton, those
+lights would have both been burning with equal
+brightness, as mine were. They did not give
+me the signal, when they passed me, because the
+lights failed to tell them that all was well."</p>
+
+<p>Grace looked up quickly. "Then, if that is
+true, Fran&ccedil;ois knew that Mr. Stapleton had
+thrown the money into the wrong car."</p>
+
+<p>"Undoubtedly, and by this time, no doubt, his
+confederates know it as well. Naturally the
+child has not been delivered. We are just where
+we were before."</p>
+
+<p>"You will arrest Fran&ccedil;ois at once, I suppose."</p>
+
+<p>"No. It will be useless. By leaving him free,
+we may learn something. By locking him up,
+with no tangible evidence against him, we accomplish
+nothing at all."</p>
+
+<p>"Then what do you advise?"</p>
+
+<p>"You will return the money to Mr. Stapleton
+at once. You can tell him, if you wish, how it
+came into your possession. He will be furious,
+of course; but he must understand that the capture
+of these scoundrels is quite as important to
+the city of Paris as the recovery of his son. We
+have done our best, and failed. We must try
+again."</p>
+
+<p><span class='pagenum'><a name="Page_152" id="Page_152">[152]</a></span>"Richard was at the Porte de Versailles," remarked
+Grace, quietly. "He tried to stop my
+car."</p>
+
+<p>"Yes. I saw him. He is coming here at
+once."</p>
+
+<p>The girl rose, in nervous haste. "I must go,
+then. It would be most unwise to have him find
+me here."</p>
+
+<p>There was a quick knock at the door. The
+Prefect rose, and opened it; then turned to Grace
+with a grim smile. "Your husband is waiting in
+the anteroom," he whispered.</p>
+
+<p>"But&mdash;what shall I do?"</p>
+
+<p>"Wait in here." Monsieur Lefevre opened
+the door which led to his private office. "You
+can hear everything quite plainly. From what
+you tell me, I should not be surprised if he insisted
+upon your arrest at once."</p>
+
+<p>"It isn't fair to him. Poor Richard! I'm
+afraid he'll never forgive me for all this."</p>
+
+<p>"Nonsense! You are engaged in a very laudable
+attempt to recover Mrs. Stapleton's child.
+So is he. Your interests are identical. Only,"
+he paused with a significant smile, "from my
+standpoint, I should much prefer that the credit
+for the boy's recovery should belong to the police<span class='pagenum'><a name="Page_153" id="Page_153">[153]</a></span>
+of Paris, of which you, for the time being, are
+one."</p>
+
+<p>Richard Duvall came into the Prefect's office,
+somewhat ill at ease. The room, familiar to him
+because of the events of the past, reminded him
+forcibly of Grace&mdash;who had, indeed been upon
+his mind constantly for the past few days. It
+was here, in this very room, that she had first
+told him that she loved him&mdash;during the exciting
+pursuit of Victor Girard, and the million francs.
+He gazed about at its familiar aspect, and
+sighed.</p>
+
+<p>"Sit down, my dear Duvall," said the Prefect,
+shaking hands with him warmly. "What, may
+I ask, brings you to Paris, at the cost of interrupting
+your honeymoon? I had supposed that
+nothing could be of sufficient importance for that.
+In fact, had I known you would consider it for
+a moment, I should have cabled to you, to give
+me your assistance in a most trying case."</p>
+
+<p>"What case, Monsieur?"</p>
+
+<p>"The mysterious kidnapping of the child of
+Monsieur Stapleton."</p>
+
+<p>"It is that very case that brings me to Paris.
+I am in Mr. Stapleton's employ."</p>
+
+<p>Monsieur Lefevre affected to be greatly surprised.<span class='pagenum'><a name="Page_154" id="Page_154">[154]</a></span>
+"Is it possible, <i>mon ami</i>? That is bad
+news indeed. This fellow Stapleton no longer
+has confidence in my office. He retains you to do
+that which he believes I shall fail to do. I am
+sorry, my dear Duvall, that we are on opposite
+sides of the fence."</p>
+
+<p>"But, Monsieur, I did not know that you
+wanted me. Mr. Stapleton is an old friend. I
+could not refuse to come to his assistance."</p>
+
+<p>Lefevre's eyes twinkled. "Have you made any
+progress, then, my friend?"</p>
+
+<p>"Yes. Tonight I put in operation a plan whereby
+I might identify an automobile containing the
+kidnappers, into which Mr. Stapleton had been
+directed to throw a package containing one hundred
+thousand dollars."</p>
+
+<p>"Indeed. You interest me. And did you succeed
+in identifying it?"</p>
+
+<p>"I did. I stopped the car, at the Porte de Versailles.
+I knew it to be the one into which the
+money had been thrown. The car was driven by
+a man named Alphonse Valentin, whom I have
+every reason to suspect is concerned in this affair.
+Its only other occupant was a woman&mdash;whom I
+met last night in Valentin's rooms, and who
+brought Mr. Stapleton a message from the kidnappers.<span class='pagenum'><a name="Page_155" id="Page_155">[155]</a></span>
+This woman is, I believe, at the bottom
+of the whole thing."</p>
+
+<p>"Indeed. And did you arrest her?"</p>
+
+<p>"No. She claims to be an agent of your
+office. Vernet, who was at the gates at my request,
+refused to place her and her companion
+under arrest. She got away with Mr. Stapleton's
+money. I believe, Monsieur Lefevre, that you
+are being made a fool of by a member of your
+own staff."</p>
+
+<p>The Prefect leaned over, and picked up the
+package containing the money which lay upon his
+desk. "I do not agree with you, my friend. Here
+is Monsieur Stapleton's money."</p>
+
+<p>Duvall started back in his chair, amazed.
+"Good Lord, Chief, am I losing my senses?
+What is this affair, anyway, a joke?"</p>
+
+<p>"Far from it, Monsieur Duvall. The criminals
+are still at large. The boy is in their hands.
+We must recover him."</p>
+
+<p>"But&mdash;this money&mdash;"</p>
+
+<p>"I arranged to get it, in order to prevent Monsieur
+Stapleton from making a fool of himself.
+I wish to capture these men&mdash;not to let them
+blackmail him out of half a million francs."</p>
+
+<p>"Had you not interfered, Monsieur Lefevre,<span class='pagenum'><a name="Page_156" id="Page_156">[156]</a></span>
+they would have been in my hands, by now. I
+would have had them safely the moment they
+attempted to enter Paris. I knew their car."</p>
+
+<p>The Prefect was filled with curiosity. "How?"
+he asked.</p>
+
+<p>"My means of a device with which Mr. Stapleton's
+car was equipped, the body of the one into
+which he threw the money was spattered with red
+paint. I could have identified it anywhere."</p>
+
+<p>"My dear Duvall! I feel that I should beg
+your pardon. Your plan was cleverness itself,
+and I will admit that, had I not interfered, you
+would in all probability have captured these men.
+I did not know what you had done, of course.
+Yet in their escape I have one consolation. It
+would have been extremely distasteful to me, to
+have had Mr. Stapleton boast that a private detective
+in his employ had succeeded, where the
+police of Paris had failed."</p>
+
+<p>"Then it would appear, Monsieur," said Duvall
+somewhat stiffly, "that we are, in this matter
+at least, in opposition."</p>
+
+<p>"Let us rather say, my friend, in competition."
+He placed his hand on Duvall's shoulder. "You
+must not blame me, if I feel a pride in my office.
+When you were working for the city of Paris,<span class='pagenum'><a name="Page_157" id="Page_157">[157]</a></span>
+you, too, felt that pride. I am truly sorry that
+I have not the benefit of your services now. However,
+I think you will admit, <i>mon ami</i>, that the
+young woman who is handing this case is no mean
+adversary." The Prefect regarded the detective
+with a quizzical smile, behind which his eyes
+twinkled merrily.</p>
+
+<p>"Who is this woman?" asked Duvall, quickly.</p>
+
+<p>"Her name is&mdash;Goncourt&mdash;Estelle Goncourt."</p>
+
+<p>"A Frenchwoman?"</p>
+
+<p>"Partly. I believe her mother was English."
+The twinkle in his eye spread&mdash;he smiled upon
+the detective with expansive good humor. "Why
+do you ask?"</p>
+
+<p>"You will think it strange, perhaps, Monsieur
+Lefevre, but when I first saw Miss Goncourt, she
+reminded me strongly of my wife."</p>
+
+<p>"Of Grace?"</p>
+
+<p>"Yes. Have you not observed it?"</p>
+
+<p>"Now that you speak of it, perhaps there is
+something similar in the manner&mdash;the carriage.
+But your wife, my dear Duvall, is a blonde, while
+Mademoiselle Goncourt is decidedly a brunette."</p>
+
+<p>"Yes. Of course. But, nevertheless, the resemblance
+is striking." He rose to go. "I hope, Monsieur,
+that this kidnapped boy may be restored<span class='pagenum'><a name="Page_158" id="Page_158">[158]</a></span>
+to his father very soon. I am anxious to return
+to America."</p>
+
+<p>"What! Leave Paris so quickly? My dear
+Duvall, I thought you Americans loved our city
+so well, that you never wanted to leave it."</p>
+
+<p>"Paris is all right, Monsieur; but," he laughed
+heartily, "I must get back to my wife and my
+farm. I was forced to leave in the very middle
+of my spring plowing."</p>
+
+<p>The Prefect roared. "You&mdash;a farmer! Mon
+Dieu! How droll! Potatoes, I suppose, and
+chickens, and dogs, and pigs&mdash;"</p>
+
+<p>"Exactly&mdash;and, believe me, Monsieur, they are
+more to my liking, than all the gaieties of Paris.
+Some day you must make us a visit, and see for
+yourself." He turned toward the door.</p>
+
+<p>"I shall, Duvall, I shall. But first we have
+to find this boy. What do you propose to do
+next?"</p>
+
+<p>Duvall smiled. "What do you?" he retorted.</p>
+
+<p>"A bottle of champagne, my friend, and a dinner
+at the Caf&eacute; Royale, that we find the child
+before you do!"</p>
+
+<p>"Done! Now I'll be off. Good night."</p>
+
+<p>The Prefect was still laughing when Grace
+peeped in from the private office, to find that<span class='pagenum'><a name="Page_159" id="Page_159">[159]</a></span>
+Richard had gone. "I think it's a shame to treat
+him so," she said. "The poor fellow! And he
+<i>would</i> have gotten the kidnappers, if we hadn't
+interfered."</p>
+
+<p>Monsieur Lefevre picked up the package containing
+Mr. Stapleton's money and placed it carefully
+in his safe. "Tomorrow you must return
+it to him," he said. "And then, I would suggest
+that you keep a close watch upon Mrs. Stapleton.
+My men have not been keeping her under surveillance.
+We have had no suspicions of her
+whatever. She may, if she is concerned in this
+matter, be imprudent enough to attempt to visit
+the child."</p>
+
+<p>"And if not?"</p>
+
+<p>"Then watch Fran&ccedil;ois. If nothing comes of
+your efforts in either direction, I fear that we
+must wait for the kidnappers to make the next
+move. Of course there is Valentin&mdash;"</p>
+
+<p>"Valentin is innocent."</p>
+
+<p>"How do you know that?"</p>
+
+<p>"I have watched him. He did everything in
+his power, tonight, to assist me. Had he been
+in league with the kidnappers, he could, after he
+knew that I had secured the money, easily have
+driven the car to some quiet spot and taken it<span class='pagenum'><a name="Page_160" id="Page_160">[160]</a></span>
+from me. I was waiting for some such move;
+but he, as you know, did not attempt it. I am
+sure that he is doing his best to assist us."</p>
+
+<p>"In that event, perhaps you can induce him to
+tell you the secret of the box of cigarettes. I feel
+sure that this knowledge would go far toward
+solving the entire affair."</p>
+
+<p>"I'll have a talk with him tomorrow."</p>
+
+<p>"Good! And now, if you are ready, we will
+return home at once."</p>
+
+<p>"Dear old Richard!" said Grace, as the Prefect
+helped her into his automobile. "I wish I
+were with him tonight."</p>
+
+<p>Lefevre smiled, and patted her hand. "So do
+I, my dear. But, remember, you have only to
+find Mr. Stapleton's child, and you can return to
+your chickens and your cows with the knowledge
+that you have done both his parents and myself
+an inestimable service."</p>

+<h2>CHAPTER XI</h2>
+
+<p class="cap extraspacetop">IT was close to eight o'clock next evening
+when Grace Duvall arrived at Mr. Stapleton's
+house with the package containing the
+money.</p>
+
+<p>She was accompanied, for safety, by two men
+from the Prefecture, who escorted her to the
+door.</p>
+
+<p>She had paid a previous visit to the house,
+during the forenoon; but Mr. Stapleton was not
+at home, and she was informed that he would
+not return until evening.</p>
+
+<p>Mrs. Stapleton she saw again; but her talk
+with the latter resulted in nothing. The poor
+lady was in utter despair, after the fiasco of the
+night before, and spent the day in her rooms,
+weeping.</p>
+
+<p>It was quite clear to Grace that her grief was
+very real. She made up her mind that, whatever
+the mystery of the gold-tipped cigarettes, Mrs.
+Stapleton had nothing to do with it. Nor had<span class='pagenum'><a name="Page_162" id="Page_162">[162]</a></span>
+the chauffeur, Valentin, been more communicative.
+He refused pointblank to explain the presence
+of the cigarettes in his room, or the reason
+why Mary Lanahan had written requesting him
+to destroy them. He said that it was a matter
+which concerned only the nurse and himself, and
+assured Grace that an answer to her questions
+would not assist in the least in recovering the
+missing child.</p>
+
+<p>Mr. Stapleton was awaiting her in the library
+when she entered. The Prefect had telephoned
+him, advising him that the money was safe, and
+would be returned to him at once. Beyond that,
+he knew nothing, except what Duvall had told
+him the night before. Consequently he was in a
+decidedly bad humor.</p>
+
+<p>Grace laid the money on the table. "Here is
+your hundred thousand dollars, Mr. Stapleton,"
+she said.</p>
+
+<p>The irate banker glared at her. "I cannot
+thank you for bringing it back, Miss," he growled.
+"Did I not particularly request that the police
+take no steps in the matter?"</p>
+
+<p>"You did, Mr. Stapleton; but we acted for
+what we thought to be your best interests."</p>
+
+<p>"Hang your thoughts about my best interests!<span class='pagenum'><a name="Page_163" id="Page_163">[163]</a></span>
+I can take care of them. If you had let things
+alone, I'd have my boy back by now."</p>
+
+<p>"And these men, these criminals, who stole him,
+would be at liberty to do the same thing over
+again tomorrow."</p>
+
+<p>Mr. Stapleton was silent for a moment. "How
+did the thing happen?" he presently asked.</p>
+
+<p>Grace told him. "The real cause of our failure,
+we believe, lies at the door of your chauffeur,
+Fran&ccedil;ois." She explained the reasons for their
+suspicions.</p>
+
+<p>Mr. Stapleton seemed puzzled. "The fellow
+seems honest enough."</p>
+
+<p>"Where is he now?" Grace inquired.</p>
+
+<p>"He asked permission to visit his people. As
+I had no use for him this evening, I told him he
+might go."</p>
+
+<p>"Ah! In that event, we may learn something.
+He is being closely watched."</p>
+
+<p>As Grace spoke, a servant entered the room.
+"There is a gentleman to see you, sir," he said
+to Mr. Stapleton.</p>
+
+<p>"Who is it?"</p>
+
+<p>"He would not give his name. He said his
+business was urgent."</p>
+
+<p>"Where is he now?"</p>
+
+<p><span class='pagenum'><a name="Page_164" id="Page_164">[164]</a></span>"In the reception room, sir."</p>
+
+<p>Mr. Stapleton rose. "Excuse me a moment,"
+he said, and went into the adjoining room.</p>
+
+<p>The library was separated from the reception
+room by a short passageway, or alcove, in which
+hung a pair of heavy curtains. Grace sat quietly,
+waiting for Mr. Stapleton to return. Suddenly
+she realized that she could distinctly hear what
+was going on in the room adjoining. For a moment
+she thought of going into the hall; then
+a word or two caught her attention, and in a
+moment she was close to the curtains, listening
+intently to a most remarkable conversation.</p>
+
+<p>The man who had asked to see Mr. Stapleton
+stood in the reception room, near a broad window
+overlooking the street without. He was tall and
+somewhat heavily built; but what at once attracted
+Grace's attention was his heavy black beard. She
+recognized him at once as the man who had
+broken into Valentin's room to steal the cigarettes,
+and had later driven the car which brought
+her back to Paris after her abduction.</p>
+
+<p>He was speaking to Mr. Stapleton in a quiet
+and assured tone, as though discussing a topic of
+no greater importance than the weather.</p>
+
+<p>"Mr. Stapleton," he said, "I have your son in<span class='pagenum'><a name="Page_165" id="Page_165">[165]</a></span>
+my possession. He is quite safe. I gave you
+an opportunity to have him returned to you last
+night; but you did not avail yourself of it."</p>
+
+<p>"I did my best," exclaimed the astounded
+banker, mastering his desire to take the fellow by
+the throat.</p>
+
+<p>"That may be; yet my plans were interfered
+with. You did not carry out my instructions."</p>
+
+<p>"I did&mdash;to the letter."</p>
+
+<p>The man frowned. "It is useless to discuss
+the matter now," he growled. "I come to give
+you one more chance. It will be the last&mdash;"</p>
+
+<p>"You damned scoundrel!"</p>
+
+<p>The man with the black beard held up his hand.
+"It will avail nothing, Monsieur," he said, calmly,
+"to excite yourself. If you want back your boy,
+listen to what I have to say."</p>
+
+<p>"Very well. Go ahead."</p>
+
+<p>"First, I want no interference by the police,
+or by the man Duvall, who is acting for you."</p>
+
+<p>Mr. Stapleton drew back in astonishment.
+"How do you know that Mr. Duvall is acting for
+me?" he said.</p>
+
+<p>"It is my business to know, Monsieur. Let it
+suffice that I <i>do</i> know. If you hope ever to see
+your child again, you had better listen to what<span class='pagenum'><a name="Page_166" id="Page_166">[166]</a></span>
+I have to say, and carry out my instructions to the
+letter." His voice was harsh, menacing.</p>
+
+<p>Mr. Stapleton directed him by a gesture, to
+proceed. He was too angry to speak.</p>
+
+<p>"Tomorrow night at this hour&mdash;eight o'clock&mdash;I
+shall come here, to this house, and ask for
+you. You will hand me a package containing one
+hundred thousand dollars. I will examine the
+money here, and satisfy myself that the amount
+is correct.</p>
+
+<p>"I shall then leave the house, and walk to the
+Arc de Triomphe; which, as you know, is but a
+short distance away. At the Arc de Triomphe,
+I shall wait for an automobile, which will stop
+for me. In that automobile I shall drive away.
+If I get away safely without interference, there
+will be telephoned to your house, within half an
+hour, the address of the place where your boy
+is to be found. If I do <i>not</i> get away safely, that
+address will <i>not</i> be telephoned to you, and you
+will not see your child alive again. This
+is your last chance, Monsieur. It is most important,
+I assure you, that nothing should happen
+to prevent my safe departure tomorrow
+night."</p>
+
+<p>For a moment Grace was undecided as to how<span class='pagenum'><a name="Page_167" id="Page_167">[167]</a></span>
+she should act. She feared greatly, under the
+circumstances, to make any move which would
+endanger the safety of Mr. Stapleton's child. Yet
+her duty, as an agent of the police, was clear.
+She must use every effort to effect this man's capture,
+before he left the house.</p>
+
+<p>She knew that she could not reach the street
+without passing the door of the reception room,
+in which case both Mr. Stapleton and his caller
+would see her. There was nothing to do but
+telephone. She flew to a small alcove room which
+opened off the rear of the library, in which she
+knew the telephone instrument was located. Once
+in this small room, she closed the door, for fear
+the others might overhear her, then called up the
+Prefecture. Monsieur Lefevre was out; but she
+acquainted one of his assistants with the circumstances,
+and requested him to send a man to the
+house at once.</p>
+
+<p>It would take at least ten minutes, perhaps
+more, for the man from the Prefecture to reach
+the house even though he came by automobile, as
+he no doubt would. What should she do, to
+keep the man in the reception room from leaving
+before the police should arrive?</p>
+
+<p>The question was solved for her, quite unexpectedly.<span class='pagenum'><a name="Page_168" id="Page_168">[168]</a></span>
+In opening the door of the small room,
+to re-enter the library, she accidentally struck
+against a chair. The sound aroused both Mr.
+Stapleton and his visitor. The former, who had,
+in his excitement, completely forgotten Grace's
+presence, appeared at once in the doorway between
+the two rooms. "Come here, Miss Goncourt,"
+he said sternly.</p>
+
+<p>Grace entered the reception room. The man
+with the black beard eyed her keenly. "Ah&mdash;a
+representative of the police, I believe. Our conversation
+has been overheard, then, Monsieur
+Stapleton?"</p>
+
+<p>The banker was violently angry. He turned
+to Grace. "You have heard?" he demanded.</p>
+
+<p>"Yes."</p>
+
+<p>"Then I insist that you do not interfere in
+the matter in any way. I intend to get my boy
+back this time, in spite of you all."</p>
+
+<p>Grace made no reply. She saw the man with
+the black beard eying her keenly. "I think,
+Monsieur, that I had better go," he remarked.</p>
+
+<p>Grace regarded him with a level look. "You
+cannot leave this house," she said. "It is being
+watched. If you attempt to do so, I will give
+the alarm."</p>
+
+<p><span class='pagenum'><a name="Page_169" id="Page_169">[169]</a></span>"And for what reason should I stay?" the man
+inquired calmly.</p>
+
+<p>"I have telephoned to the Prefecture. A man
+will be here in a few minutes, to place you under
+arrest. I advise you to remain here quietly until
+he arrives."</p>
+
+<p>The kidnapper strolled over to the window
+which overlooked the Avenue Kleber, drew aside
+the curtain, and looked out. Grace wondered
+if he was making a signal of any sort to confederates
+outside. He gazed into the street intently
+for a moment, then turned back toward the
+center of the room. "I shall follow your advice,
+Mademoiselle, and wait," he remarked, calmly.</p>
+
+<p>Mr. Stapleton was speechless with rage. He
+dared not do anything; for he knew that he would
+only lay himself open to a charge of resisting the
+police, and helping a criminal to escape. He sat
+in his chair, inwardly cursing Grace and the entire
+police force of Paris as well.</p>
+
+<p>None of the three spoke for a considerable
+time. After what seemed to Grace ages, she
+heard the faint ringing of the doorbell, and presently
+the frightened servant arrived, with the
+information that a detective from the Prefecture
+was in the hall, and desired to see Mr. Stapleton<span class='pagenum'><a name="Page_170" id="Page_170">[170]</a></span>
+immediately. He had scarcely succeeded in delivering
+this message, when a heavily built man
+in citizen's clothes shouldered past him into the
+room.</p>
+
+<p>He gazed quickly about. Grace did not remember
+having ever seen him before. "I am
+from the Prefect of Police," he announced, striding
+toward the kidnapper. "I am here to arrest
+this man." In a moment the click of the handcuffs,
+as he snapped them upon the wrists of the
+man with the black beard, came to Grace's ears.</p>
+
+<p>The kidnapper smiled pleasantly. "I am quite
+ready to accompany you, my friend," he said.</p>
+
+<p>Mr. Stapleton was regarding the scene in helpless rage.
+He resented bitterly the way in which
+the police continually interfered with his plans to
+get back his child. In one way, he was glad to
+feel that the guilty man was under arrest; but, if
+it resulted in the death of the missing boy, it
+would be a tragedy, indeed. He turned to the
+man with the black beard who stood, smiling,
+near the door. "I hope you will understand," he
+said, "that I have nothing to do with this matter&mdash;nothing
+whatever. The presence of this woman
+here was a pure accident. I had forgotten that
+she was in the next room. I'd be glad enough to<span class='pagenum'><a name="Page_171" id="Page_171">[171]</a></span>
+see you put behind the bars for the rest of your
+life; but not if it is going to prevent me from
+getting back my child."</p>
+
+<p>The man with the black beard continued to
+smile pleasantly. "I believe you, my friend," he
+said. "However, there is no harm done. When I
+return tomorrow night&mdash;for I shall return, depend
+upon it, in spite of the efforts of this gentleman,"
+he waved his hand lightly toward the
+man from the Prefecture, "I trust that you will
+have persuaded Monsieur Lefevre, and your man
+Duvall as well, to let me do so in peace. It is
+the only way in which anything can be accomplished&mdash;I
+assure you of that." He turned to
+his captor. "I am ready to accompany you, Monsieur."</p>
+
+<p>The officer started toward the door leading
+into the hall. He had taken but a single step
+when the servant, with a frightened look upon
+his face, appeared in the doorway. "Mr. Stapleton,"
+he stammered, "there is a man here from
+the office of the Prefect of Police."</p>
+
+<p>Stapleton strode toward the door. "Another?"
+he exclaimed. "What does this mean?"</p>
+
+<p>The man in charge of the kidnapper stepped
+forward, speaking in a quick, low tone. "Leave<span class='pagenum'><a name="Page_172" id="Page_172">[172]</a></span>
+the matter to me, Monsieur," he whispered.
+"This fellow who has just arrived is an impostor,
+a confederate. He pretends to be an agent
+of the police, in order to rescue his comrade, who
+has undoubtedly signaled to him from the window.
+Be good enough to step into that room,"
+he pointed to the library, "and let me deal with
+him."</p>
+
+<p>Mr. Stapleton hesitated. "What do you propose
+to do?" he asked.</p>
+
+<p>"Quick!" said the other, offering no explanations.
+"He will be here at once." He turned
+to the astonished servant. "Bring the man in."</p>
+
+<p>The puzzled banker moved toward the adjoining room.
+"You will accompany him, please," the
+Prefect's man said to Grace. "There may be
+danger."</p>
+
+<p>"I am not afraid, Monsieur," replied Grace,
+who did not entirely like the way things were
+going.</p>
+
+<p>The man, however, paid no attention to her
+remonstrances. "Go&mdash;at once, I command you,
+in the name of the law!"</p>
+
+<p>She hesitated no longer, but followed Mr.
+Stapleton into the library. As she did so, the
+new arrival entered the reception room.</p>
+
+<p><span class='pagenum'><a name="Page_173" id="Page_173">[173]</a></span>The man with the black beard stood to one
+side of the doorway. His captor advanced toward
+the newcomer. "I have him here," he exclaimed,
+pointing to the kidnapper, "safely
+ironed."</p>
+
+<p>"Who are you?" curtly inquired the man who
+had just entered the room.</p>
+
+<p>"A private detective. Here is your man. Let
+us get him out of here at once."</p>
+
+<p>The official made no reply, but stepped quickly
+up to the man with the black beard. "Come
+along with me," he said, roughly, and placed his
+hand upon the other's arm.</p>
+
+<p>As he did so, the kidnapper shook his wrists
+briskly. The handcuffs fell clattering to the floor.
+Without a word he threw his powerful arms about
+the neck of the astonished official, and throttled
+him into instant silence. His companion, no less
+quick, whipped out a handkerchief, and knotted it
+about the official's mouth. He was unable to
+utter a sound.</p>
+
+<p>The whole thing was so quickly done that
+Grace, who was watching the room through the
+curtains in the doorway, had barely time to utter
+a cry, before the newcomer was lying helpless
+and silent upon the floor, choked into insensibility;<span class='pagenum'><a name="Page_174" id="Page_174">[174]</a></span>
+while the two men, quite evidently confederates,
+made ready to go.</p>
+
+<p>The black-bearded fellow quickly replaced the
+handcuffs upon his own wrists. "Quick, Ramond,"
+he cried. "Let us get out at once."</p>
+
+<p>Grace was by this time in the room. She knew
+that she must in some way prevent these men
+from escaping. But how&mdash;how? They glared
+at her ominously. The younger man drew a
+revolver. Before any of them could speak, the
+servant appeared in the doorway for the third
+time. His face was pale as death. His knees
+knocked together from terror as he beheld the
+gleaming revolver, the man lying upon the floor.</p>
+
+<p>"Monsieur Duvall is here!" he gasped, and
+stood silent.</p>
+
+<p>The man on the floor, recovering his senses,
+began to struggle to his feet. As he did so, Duvall
+pushed his way past the frightened servant
+and strode into the room.</p>
+
+<p>"Quick, Monsieur Duvall!" the fellow with the
+revolver cried. "I am from the Prefecture. I
+have one of the kidnappers in irons. The other,"
+he pointed to the struggling man on the floor,
+"is about to escape me. Give me your assistance
+at once!"</p>
+
+<p><span class='pagenum'><a name="Page_175" id="Page_175">[175]</a></span>Grace was so astounded by the sudden entrance
+of her husband, as well as by the kidnapper's
+words, that for a moment she remained speechless.
+Duvall bent over the man upon the floor
+and seized him by the throat.</p>
+
+<p>"Richard! Richard!" Grace screamed, forgetful
+of Monsieur Lefevre and her own disguise.
+"Look out!"</p>
+
+<p>Almost before the words had left her lips, the
+man with the revolver brought it down with a
+dull thud upon Duvall's head as he bent over the
+prostrate man; then, grasping his companion by
+the arm, he rushed from the room.</p>
+
+<p>"Richard! Richard!" screamed Grace, throwing
+her arms about the senseless body of her
+husband.</p>
+
+<p>Mr. Stapleton, who had entered the room, regarded
+her in amazement. "What are you
+doing?" he exclaimed.</p>
+
+<p>Grace rose, her face white with suffering. "A
+doctor, quick! He is hurt! My God&mdash;don't you
+see? He is hurt!" As she spoke, she fell back,
+fainting, to the floor.</p>

+<h2>CHAPTER XII</h2>
+
+<p class="cap extraspacetop">WHEN Richard Duvall returned to consciousness,
+an hour later, he lay upon
+a couch in Mr. Stapleton's library. A
+doctor, hastily summoned, was bending over him.
+Mr. Stapleton sat grimly in an arm chair. There
+was no one else in the room.</p>
+
+<p>"My wife! Is she here?" the detective cried,
+as he tried to rise.</p>
+
+<p>The doctor pushed him gently back. "Compose
+yourself, Monsieur," he said in a soothing
+voice. "You are not badly hurt. Merely stunned
+for the moment. A slight cut&mdash;that is all. You
+will be quite yourself again in half an hour."</p>
+
+<p>"But my wife!" He gazed eagerly about
+the room.</p>
+
+<p>"What do you mean, Duvall?" inquired Mr.
+Stapleton, calmly. "Why do you think your wife
+is here?"</p>
+
+<p>"A trace of delirium. He will be all right in<span class='pagenum'><a name="Page_177" id="Page_177">[177]</a></span>
+a few moments. Very usual in such cases," the
+doctor whispered.</p>
+
+<p>"I heard her voice. She called to me by name,
+just as that fellow struck me."</p>
+
+<p>"My dear sir, your mind is wandering. Compose
+yourself, I beg." The doctor attempted to
+press his patient back upon the pillows.</p>
+
+<p>Duvall passed his hand over his forehead, completely
+bewildered. "I could have sworn I heard
+her voice," he cried.</p>
+
+<p>"It was Miss Goncourt, the young woman from
+the Prefecture, that you heard, Duvall," remarked
+Mr. Stapleton quietly. He did not tell
+the detective that Grace, on recovering from her
+faint, and learning from the doctor that Richard's
+wound was a superficial one only, and not
+at all serious, had sworn them both to secrecy,
+on the plea that the matter was a purely private
+one, and likely to cause her great unhappiness
+if divulged. Mr. Stapleton had agreed, but had
+done so only upon her agreeing not to acquaint
+the police with his plans for the following night.</p>
+
+<p>She had suddenly conceived a violent animosity
+toward these fellows who had not only baffled
+both her husband and herself, but had made the
+former a victim of a dangerous assault. She was<span class='pagenum'><a name="Page_178" id="Page_178">[178]</a></span>
+determined to go to work in desperate earnest,
+to capture them, or locate the child, before the
+following evening. She had promised Mr.
+Stapleton not to acquaint Monsieur Lefevre with
+the plan for returning the child which the man
+with the black beard had proposed. The situation
+put her on her mettle. She determined to
+get at the bottom of the whole affair before
+another twenty-four hours had passed. Upon
+leaving the house she called a taxicab, and at
+once ordered the chauffeur to drive her to the
+point on the Versailles road where, according to
+Valentin, she had been placed in the automobile
+after her interview with the kidnappers. Here,
+she believed, lay the starting point of the whole
+mysterious affair.</p>
+
+<p>Duvall, his consciousness returning, insisted
+upon getting up from the couch, and going to
+work with equal determination. The way in
+which he had been checkmated, in the whole
+affair, roused him, as well, to desperation. His
+professional skill, upon which the banker had set
+such great store, seemed to have deserted him.
+He felt humiliated, ashamed. In three days, he
+had accomplished nothing whatever. It was galling
+in the extreme.</p>
+
+<p><span class='pagenum'><a name="Page_179" id="Page_179">[179]</a></span>Mr. Stapleton's explanations of his hallucination
+regarding his wife he accepted as true. The
+resemblance which Miss Goncourt bore to Grace,
+together with his constant thoughts of her, were,
+he argued, no doubt responsible for it. The
+blow upon the head made his recollections of the
+moments immediately preceding and following
+the assault extremely hazy. He put the matter
+out of his mind, and set to work with renewed
+energy.</p>
+
+<p>So far, it seemed, he had met with but a single
+clue of any importance,&mdash;the cigarette with the
+gold tip which he had found in the Bois de Boulogne.
+He determined to follow this clue until
+he arrived at some definite result.</p>
+
+<p>As soon as the doctor had departed after dressing
+the wound in his head, Duvall took a stiff
+drink of brandy, and, sitting down with Mr.
+Stapleton at the latter's desk, began to reconstruct,
+as far as he could, all the details of the kidnapping.
+He spoke his thoughts aloud, taking Mr.
+Stapleton into his confidence, since in this way
+he could most readily get his ideas into concrete
+form.</p>
+
+<p>"Mr. Stapleton, I am, I confess, greatly humiliated
+at the progress, or lack of progress, which<span class='pagenum'><a name="Page_180" id="Page_180">[180]</a></span>
+I have made in this case so far. I have made up
+my mind, however, to get these fellows, if it takes
+me the rest of the summer."</p>
+
+<p>"You will have to work more quickly than that,
+Mr. Duvall," observed the banker coldly. "I
+have made arrangements to recover my child by
+tomorrow night."</p>
+
+<p>"You are going to buy these rascals off, then?"</p>
+
+<p>"Yes."</p>
+
+<p>"How?"</p>
+
+<p>"I decline to say. I've had enough interference
+with my plans already. Neither you nor the
+police have accomplished anything. Miss Goncourt
+knows what I propose to do; but she has
+given me her word not to interfere. If you are
+to accomplish anything, it must be before eight
+o'clock tomorrow night."</p>
+
+<p>"Very well. I will make my plans accordingly."</p>
+
+<p>"What do you propose to do?"</p>
+
+<p>"That I cannot say, at the moment. I think,
+however, that I shall first try to find out who it
+is that smokes these gold-tipped cigarettes." He
+drew the fragment of cigarette which he had
+found from his pocket, and placing it on the
+desk before him regarded it critically.</p>
+
+<p><span class='pagenum'><a name="Page_181" id="Page_181">[181]</a></span>Mr. Stapleton gave a grunt. "What are they,
+Exquisites?"</p>
+
+<p>"Yes. How did you know?"</p>
+
+<p>The banker laughed. "Easy enough. My wife
+smokes them."</p>
+
+<p>The detective looked up quickly. "Indeed!
+Brings them from America with her, I suppose."</p>
+
+<p>"Yes."</p>
+
+<p>Duvall began mentally to check off, in his mind,
+the various persons who might have used the
+cigarette which lay before him. Valentin, he
+now believed, was out of the question. His presence
+in the automobile, with Grace, the night
+before, indicated that he had nothing to do with
+the kidnappers.</p>
+
+<p>There remained Mrs. Stapleton. Duvall had
+talked with her&mdash;seen her grief. He was too
+shrewd a judge of human nature to think for a
+moment that it was assumed.</p>
+
+<p>Who else? Suddenly an idea flashed into his
+mind. He wondered that he had not thought of
+it before. The nurse! He recalled vividly the
+marks he had observed on the dresser in the
+woman's room in New York.</p>
+
+<p>"Is Mary Lanahan in the house?" he inquired
+of Stapleton.</p>
+
+<p><span class='pagenum'><a name="Page_182" id="Page_182">[182]</a></span>"Yes. Why?"</p>
+
+<p>"Kindly have her come here."</p>
+
+<p>Mr. Stapleton pressed a button on his desk in
+silence. In a few moments, the nurse had been
+brought to the room by one of the other servants.
+She was haggard with grief and fear.</p>
+
+<p>Duvall requested her to be seated, and began
+to ask her a number of apparently unimportant
+questions regarding the kidnapping.</p>
+
+<p>She answered them frankly enough, although
+it was clear that she was very ill at ease.</p>
+
+<p>Presently Duvall got up, and, calling Mr.
+Stapleton to one side, asked him, in a low tone,
+to detain the nurse in the library for a few moments.
+He wished to search her room.</p>
+
+<p>"But it has already been thoroughly searched
+by the police."</p>
+
+<p>"I know. But I must search it again. It will
+require but a few moments."</p>
+
+<p>Stapleton nodded. "I will wait for you here,
+Mr. Duvall," he said. "Mary, you will wait,
+as well."</p>
+
+<p>The nurse's room was on the third floor, in a
+rear building. Duvall found it, after some slight
+difficulty, with the assistance of one of the other
+servants.</p>
+
+<p><span class='pagenum'><a name="Page_183" id="Page_183">[183]</a></span>He seemed, on entering the room, to have but
+one object in view. He went at once to the mantel,
+and, taking from it the two small bottle-shaped
+vases which stood upon it, shook them both vigorously.
+A faint rattling sound came from the
+second. He turned it upside down upon the
+palm of his hand, and there tumbled out a
+quantity of ashes, and the butts of several
+partly smoked cigarettes. With a quiet smile he
+replaced them in the vase, and returned to the
+library.</p>
+
+<p>"Mary, you may go now," he said.</p>
+
+<p>When the woman had gone, he turned to Mr. Stapleton.
+"It was Mary Lanahan herself who smoked the cigarette
+which I found in the grass," he said.</p>
+
+<p>"Well, what of it?" The matter seemed to
+the banker to be utterly without significance.</p>
+
+<p>"She had, no doubt, stolen them from Mrs. Stapleton."</p>
+
+<p>"Very likely. Not a very serious matter, however."</p>
+
+<p>"No. But the question now arises, Why did she
+turn the box over to Valentin, and subsequently
+ask him to destroy it?"</p>
+
+<p>"I cannot imagine."</p>
+
+<p><span class='pagenum'><a name="Page_184" id="Page_184">[184]</a></span>"And why, later, were these cigarettes stolen
+from Valentin, as I understand they were?"</p>
+
+<p>"It's too much for me. What do you make
+of it?"</p>
+
+<p>"I have a theory, Mr. Stapleton; but I cannot
+say just what it is&mdash;yet. By the way, where is
+your man, Fran&ccedil;ois, tonight?"</p>
+
+<p>"He is visiting his people, somewhere in the
+suburbs."</p>
+
+<p>"Ah! Then I would like to search his room,
+as well."</p>
+
+<p>"Go ahead. You will find nothing, I fear.
+The police have gone over it with a fine-tooth
+comb." He rose. "Come along, I'll go with you."</p>
+
+<p>The room occupied by the chauffeur was at the
+very top of the house, with two windows opening
+through the slanting mansard roof. One of
+these, Duvall noted, commanded a view over the
+houses adjoining toward the north, beyond which
+could be seen the Avenue du Bois de Boulogne.
+A second window, toward the south, commanded
+an extensive view toward Passy.</p>
+
+<p>Mr. Stapleton, puffing because of the unaccustomed
+stairs, sat down upon the bed. "I cannot
+imagine what you hope to find here, Duvall," he
+grumbled.</p>
+
+<p><span class='pagenum'><a name="Page_185" id="Page_185">[185]</a></span>The detective made no reply, but began a systematic
+inspection of the room. One of the first
+objects which attracted his attention was an ordinary
+electric searchlight, of the pocket variety,
+lying on the man's dresser. He picked it up, and
+examined it carefully.</p>
+
+<p>"I got it for Fran&ccedil;ois," observed Mr. Stapleton,
+"so that he could examine the car, at night,
+in case of any accident or repair."</p>
+
+<p>"Of course. Very useful, too. But why, I
+wonder, does he keep it here in his room, instead
+of in the garage?"</p>
+
+<p>"Possibly to light himself up the stairs, at
+night," said Stapleton.</p>
+
+<p>"Then I should think he would have it with
+him," remarked Duvall, dryly. "Wouldn't be
+of much use to him tonight, for instance." He
+was about to put the thing down, when his attention
+was attracted by two objects, hanging one
+on each side of the dresser, from its two uprights.
+They were apparently Christmas tree ornaments,
+made of thin glass, and they hung from the back
+of the dresser by means of two bits of ribbon.</p>
+
+<p>They seemed at first glance to be merely souvenirs
+of some party, some entertainment, which
+the chauffeur had preserved as mementos of the<span class='pagenum'><a name="Page_186" id="Page_186">[186]</a></span>
+occasion. They were shaped like little cups, with
+a paper fringe about the top, to which the gay ribbons
+were attached. Duvall had seen such ornaments
+often before, at Christmas time. They were
+intended to be hung from the tree by their ribbons,
+and were filled with small candies or bonbons.
+He had almost passed them by, when something
+in their colors caused him to pause. One was a
+deep blue, the other an equally deep red. He
+examined the wooden uprights of the dresser
+with great care. All along the top of the dresser
+at its back was a heavy coating of dust. The top
+of the uprights, over which the loops of ribbon
+which supported the little baskets had been
+passed, contained no dust whatever.</p>
+
+<p>Evidently the baskets had been taken down,
+and that too quite recently. For what purpose?
+he wondered. Suddenly he had an inspiration.
+He took down the little blue basket, and quickly
+placed it over the end of the searchlight. It
+fitted perfectly, the paper collar at its top holding
+the glass hemisphere snugly in place.</p>
+
+<p>Mr. Stapleton was watching Duvall without
+particular interest. Suddenly the detective pointed
+the searchlight toward him and pressed the button
+which threw on the current. Mr. Stapleton<span class='pagenum'><a name="Page_187" id="Page_187">[187]</a></span>
+started back, as his face was flooded with a beam
+of brilliant blue light.</p>
+
+<p>Duvall replaced the little basket in the same
+position in which he had found it, and laid the
+searchlight upon the dresser. "Rather neat,
+isn't it?" he exclaimed.</p>
+
+<p>"What do you make of it?" asked the banker.</p>
+
+<p>"Your man Fran&ccedil;ois evidently is in the habit
+of making signals," the detective replied, laughing.
+He was beginning to feel hopeful. The
+search of the two rooms was bearing fruit.</p>
+
+<p>For the next half-hour, Duvall went over the
+contents of the chauffeur's room with the utmost
+care. He removed and replaced, just as he found
+them, the contents of the dresser drawers. He
+opened a small wooden trunk which stood at one
+side of the room, and examined its contents minutely.
+He explored the closet, looked behind the
+pictures, sounded the walls. Nothing further of
+an unusual nature rewarded his efforts. Still he
+seemed unsatisfied.</p>
+
+<p>"What more can you hope to find, Mr. Duvall?"
+inquired the banker, who had begun to
+find the proceedings tiresome.</p>
+
+<p>The detective stood in the center of the room,
+and glanced about in some perplexity. "I had<span class='pagenum'><a name="Page_188" id="Page_188">[188]</a></span>
+hoped to find one thing more," he said; "but
+I am afraid it isn't here."</p>
+
+<p>Suddenly he strode over to the mantel, upon
+which stood a small nickel-plated alarm clock of
+American make.</p>
+
+<p>"This clock doesn't seem to be going," he remarked,
+then whipped out his magnifying glass
+and carefully studied the brass handle which projected
+from the back, by which it was wound up.
+"It hasn't been wound for several days, either.
+The back is covered with dust." He picked up
+the clock and tried to wind it; but the handle resisted
+his efforts.</p>
+
+<p>In an instant he took out his knife, and a moment
+later was removing the screws which held
+the metal back of the clock in place.</p>
+
+<p>Mr. Stapleton watched him curiously. Duvall's
+methods savored, to him, of the accepted sleuth
+of fiction. He took little stock in the tiny clues
+upon which the whole modern science of criminology
+is built.</p>
+
+<p>In a few moments the detective had removed
+the screws and lifted out the rear plate of the
+clock. As he did so, he gave a grunt of satisfaction.
+A small pasteboard box fell out upon
+the mantel.</p>
+
+<p><span class='pagenum'><a name="Page_189" id="Page_189">[189]</a></span>"What is it?" asked Stapleton.</p>
+
+<p>"The box of cigarettes," remarked Duvall, as
+he opened it. "There are three missing. I shall
+take a fourth." He selected one of the paper-covered
+tubes, placed it within his pocketbook,
+then thrust the box back into the clock, and rapidly
+replaced the metal plate.</p>
+
+<p>"I don't think there is anything further to be
+done here, Mr. Stapleton," he remarked. "I
+think I'll be getting along to my room. Tomorrow
+I shall be quite busy."</p>
+
+<p>He stopped for a moment, on his way out, to
+glance from the window which faced toward the
+north. Between the buildings and trees ran the
+Avenue du Bois de Boulogne, its course illuminated
+by many street lamps, and the flashing lights
+of passing motor cars. Duvall gazed intently at
+the scene before him for a few moments, then
+turned to the door, and, accompanied by Mr.
+Stapleton, descended the stairs.</p>
+
+<p>As he was about to leave the house, the banker,
+who evidently had something on his mind, stopped
+him.</p>
+
+<p>"Mr. Duvall," he said, earnestly, "I would
+like very much to know what you intend to
+do."</p>
+
+<p><span class='pagenum'><a name="Page_190" id="Page_190">[190]</a></span>"I'm going to catch these fellows, if I possibly
+can," the detective replied, earnestly.</p>
+
+<p>"What steps do you propose to take?"</p>
+
+<p>"I cannot exactly say&mdash;yet. Why do you
+ask?"</p>
+
+<p>"I'll tell you. The fellow who was here tonight,
+the one with the black beard, is coming to
+see me tomorrow night, at eight o'clock. I cannot
+tell you more than that. I did not intend to
+tell you that much&mdash;but I am obliged to do so."</p>
+
+<p>"Obliged! Why?"</p>
+
+<p>"Because I want your promise that you will
+make no attempt to stop him. If I had said nothing,
+you might have watched the house, and, upon
+recognizing the fellow as the one who was here
+tonight, have placed him under arrest. I want
+you to do nothing to interfere with either his
+coming or his going. He will be safe, after he
+once leaves the Arc de Triomphe in his automobile."</p>
+
+<p>"But the police?"</p>
+
+<p>"They know nothing of the matter. Miss Goncourt
+has given me her word to remain silent.
+She has even agreed to have the men on watch
+about the house withdrawn. Both you and the
+police may do your best to catch this man, after<span class='pagenum'><a name="Page_191" id="Page_191">[191]</a></span>
+I have carried out my compact with him; but until
+then I want you to keep your hands off."</p>
+
+<p>Duvall was silent for a moment. "Very well,
+Mr. Stapleton, I shall do as you say. In fact,
+to assure you that I am carrying out your wishes,
+I will agree to remain here with you, at the
+house, throughout the evening."</p>
+
+<p>"Good! I shall expect you. Good night."</p>
+
+<p>"Good night." Duvall left the house, and went
+at once to his hotel.</p>
+
+<p>Here, a few moments later, he seated himself
+in an easy chair, and taking from his pocket the
+cigarette which he had secured in the chauffeur's
+room, regarded it critically.</p>
+
+<p>After some little time, he took a match from
+a box upon a nearby table, and, placing the gold
+tip of the cigarette between his lips, carefully lit
+it.</p>
+
+<p>He drew the smoke into his lungs, inhaling it
+deeply. Once&mdash;twice&mdash;three times he repeated
+the operation, then threw himself back into his
+chair, and, closing his eyes, sat buried in thought.
+In his preoccupation, he allowed the end of the
+cigarette to fall unheeded to the floor.</p>
+
+<p>After many minutes he opened his eyes and
+started up. "I've got it!" he cried, and, picking<span class='pagenum'><a name="Page_192" id="Page_192">[192]</a></span>
+up the half-burned cigarette from the floor, threw
+it carelessly into the fireplace.</p>
+
+<p>Then he sat down at his table, drew out a
+sheet of paper and a map of the city of Paris,
+and began to make a series of drawings and calculations
+that occupied him far into the night.</p>
+

+<p><span class='pagenum'><a name="Page_193" id="Page_193">[193]</a></span></p>
+<h2>CHAPTER XIII</h2>
+
+<p class="cap extraspacetop">IT was nearly ten o'clock when the taxicab
+containing Grace Duvall stopped alongside
+the road, at a point some four miles beyond
+the city, in the direction of Versailles. She had
+been unable to give the driver the exact location
+at which she desired to be put down, but had
+directed him to drive on until she told him to
+stop.</p>
+
+<p>The spot was quite familiar to her, owing to
+the hours she had spent in the vicinity with the
+searching party the day before.</p>
+
+<p>The taxicab driver seemed rather surprised to
+see her alight at this somewhat lonely spot; but
+he shrugged his shoulders with true Parisian indifference,
+pocketed the tip she gave him, and
+drove rapidly off in the darkness.</p>
+
+<p>Left to herself by the roadside, Grace began
+to fear that she had, after all, done a rather
+foolish thing. Now that she was here, she hardly
+knew how to begin.</p>
+
+<p><span class='pagenum'><a name="Page_194" id="Page_194">[194]</a></span>All about her she saw the dark outlines of
+cottages among the trees, with here and there a
+straggling light which betokened some household
+late in getting to bed. The country people in
+this vicinity&mdash;growers of flowers and vegetables
+or dairymen for the most part&mdash;were asleep with
+their cows about the time that Paris began to
+dine.</p>
+
+<p>Occasionally the silence about her was broken
+by the mournful howling of a dog; but otherwise
+all was still.</p>
+
+<p>The night was cloudless, and the lightening of
+the sky toward the east told her that before long
+a moon would rise above the trees.</p>
+
+<p>Near the road she found a little rustic bench,
+and upon this she sat down to think.</p>
+
+<p>The howling of the dog had suggested to her
+mind a possible clue to the house within which
+Mr. Stapleton's boy had been, for a time at least,
+confined. She could remember nothing of the
+garden, and but little of the room in which she
+had been confined; but the dog, playing upon the
+grass with the child, had fixed itself in her memory.
+She recollected distinctly that he was a
+poodle, mostly black, with fine curling hair, like
+astrakhan fur, and a pointed nose.</p>
+
+<p><span class='pagenum'><a name="Page_195" id="Page_195">[195]</a></span>There were many dogs of this sort, she well
+knew, and yet there was one peculiarity which
+had impressed itself upon her memory, which
+would inevitably serve to identify this particular
+dog, should she ever see him again. His long
+and bushy tail, black for the most part like the
+rest of his body, terminated in a plume of white
+hair.</p>
+
+<p>It was a most unusual marking in a French
+poodle. She had never seen it before, and she
+was a great lover of dogs, and knew them thoroughly.
+It was this fact, no doubt, which had
+caused her to notice the animal, at a time when
+her mind was filled with matters of vastly greater
+importance.</p>
+
+<p>She had sought carefully for such a dog, on
+the occasion of the previous search, but had not
+found him. The tale about the escaped cobra
+had caused the country folk to lock up their pets
+without loss of time.</p>
+
+<p>Now she hoped to find this dog, and through
+him discover the location of the house in which
+she had been confined. After that&mdash;well, she
+would do the best she could.</p>
+
+<p>It occurred to her that she was not at all
+likely to discover the whereabouts of the black<span class='pagenum'><a name="Page_196" id="Page_196">[196]</a></span>
+poodle by sitting here on a bench; yet she dared
+not start out until the moon had risen sufficiently
+high to light up her way.</p>
+
+<p>In about an hour, the rim of the golden disk
+showed itself above the treetops, and a little
+later the black shadows about her began to grow
+luminous, and resolve themselves into white-walled
+cottages, hedges, and outbuildings of various
+sorts.</p>
+
+<p>A narrow lane ran off from the main road,
+bordered on each side by lindens and poplars.</p>
+
+<p>Along this lane the houses of the little hamlet
+were set, some near the road, others quite a distance
+back. She rose, and began to walk slowly
+along the lane.</p>
+
+<p>As she had expected, dogs of various sorts and
+sizes, to judge by their voices, began barking as
+soon as she came opposite the first house. A
+small fox terrier ran through the gateway of a
+garden, yelping sharply. The deep-toned baying
+of a hound sounded farther up the street.
+A small white poodle, and a black one of the
+same size, ran after her, as she went along,
+making friendly attempts to play. The one she
+sought, however, seemed nowhere in evidence.</p>
+
+<p>The lane ascended a gently sloping hill, at the<span class='pagenum'><a name="Page_197" id="Page_197">[197]</a></span>
+top of which stood a house, somewhat larger
+than the others, whose outbuildings and pastures
+proclaimed it to be a dairy farm. There was a
+hedge of roses along the roadside, and a little
+wooden gate.</p>
+
+<p>Grace heard a sharp bark on the other side
+of the gate as she passed it, and, stopping, glanced
+over. In the shadow stood a black poodle; but
+whether his tail showed the markings for which
+she sought she was unable to tell on account of
+the darkness. She gave the gate a gentle push,
+and it slowly opened. The dog ran out into the
+road. As he crossed a patch of moonlight, she
+saw that her search was ended. This, she was
+convinced, was the dog&mdash;and the house!</p>
+
+<p>Her next problem was how to get inside. Try
+as she would, she could think of no excuse which
+would adequately account for her presence in this
+little frequented locality at such a time of night.
+That the occupants of the house had long ago
+retired was evidenced by the blackness of the
+windows, the silence which brooded over the
+whole place.</p>
+
+<p>She looked about her. Just across the lane
+from the little gate a building loomed formless
+against a shadowy clump of trees. She went over<span class='pagenum'><a name="Page_198" id="Page_198">[198]</a></span>
+to it, and found that it was a small shed. The
+door stood open. Inside stood a tumbledown old
+wagon, dust covered, and quite evidently unused
+for a long time. The shelter of the shed seemed
+grateful&mdash;as though she had arrived somewhere,
+instead of being a wanderer in the night.</p>
+
+<p>There seemed nothing to do, now, but wait for
+daylight. She climbed into the creaking wagon
+and sat upon the seat. There was a back to it,
+which, like the seat, was covered with old and
+torn velveteen. She leaned back in the shadow
+and closed her eyes. Her walk, the night air,
+had made her tired. In the distance she
+heard, after a long time, the faint booming
+of a bell. She looked at her watch. It was midnight.</p>
+
+<p>The next thing that Grace remembered was the
+loud barking of a dog. She sat up, feeling stiff
+and cold. Her neck and left shoulder ached painfully.
+A glance through the open door of the
+shed told her that it was still night; but there was
+a gray radiance in the air, a soft pale light, that
+betokened the coming of dawn.</p>
+
+<p>She crept stiffly down from the wagon, and
+again consulted her watch. It marked the hour
+of four. Through a dusty window in the side<span class='pagenum'><a name="Page_199" id="Page_199">[199]</a></span>
+of the shed she saw the eastern sky, rose streaked
+and bright, heralding the sun.</p>
+
+<p>As the light increased, she saw the dog that
+had disturbed her sleep running about on the
+grass in front of the house opposite. The house
+seemed much nearer, in the daylight, than it had
+appeared at night. She examined the dog closely.
+The white tip of his tail, waving gaily in the morning
+light, showed her that it was the one she had
+sought.</p>
+
+<p>She crouched in the dim shadow of the half-open
+door and watched the scene before her.
+There was a man, moving about among the small
+buildings to the right. She heard him performing
+some task&mdash;she could not at first make out
+what. Presently the lowing of cattle, the rattle
+of a bucket, as it was drawn up by a creaking
+windlass, told her that the man was tending his
+cows.</p>
+
+<p>Quite half an hour later she saw him going
+toward the house, a pail, evidently well filled, in
+each hand.</p>
+
+<p>Then ensued another long silence. The curling
+wisp of smoke from the chimney of the cottage
+indicated breakfast, and Grace suddenly
+realized that she felt cold, and hungry. For the<span class='pagenum'><a name="Page_200" id="Page_200">[200]</a></span>
+first time in her life she realized how important
+one's breakfast is, in beginning the day.</p>
+
+<p>Presently the man reappeared and went toward
+a small building which Grace took to be the barn.
+She could see him clearly now; for the sun had
+risen above the trees and lit up the whole scene
+brilliantly. He was a small, wizened man, with
+gray hair and a slight stoop. She was quite certain
+that she had never seen him before.</p>
+
+<p>He went to the barn, and she saw that he was
+engaged in harnessing a horse, which he presently
+attached to a farm wagon. She noted the wagon
+particularly. It was a low two-wheeled affair,
+with a dingy canvas top. A large patch in the
+canvas showed yellow-white in the sunlight. The
+horse was white.</p>
+
+<p>In a little while the man began to put in the
+cart a variety of objects which he brought from
+the barn. They appeared to be baskets of vegetables
+or fruit, and cans of milk. Presently he
+stopped, and went toward the house. In a few
+minutes he returned. This time a woman was
+with him. They carried between them a large
+wicker basket, which appeared to be quite heavy.
+There was a top on the basket. Grace wondered
+if it could be filled with laundry.</p>
+
+<p><span class='pagenum'><a name="Page_201" id="Page_201">[201]</a></span>The couple placed the basket in the wagon,
+putting it in from the front, so that it occupied
+a position close beside the driver. In getting it
+up over the wheel the woman let her end of it
+slip, and the man cursed her with such sudden
+sharpness that Grace was startled and crouched
+back into the shed. She wondered what the
+basket could contain, that made the man so careful,
+and the thought came to her, might it not
+be Mr. Stapleton's boy?</p>
+
+<p>The idea possessed her completely. As the
+man drove out into the lane, and rattled down
+the hill toward the main road, she suddenly realized
+that she must follow; yet how could she
+hope to do so, on foot? The woman had gone
+back into the house. Regardless of consequences,
+Grace ran out into the lane, and after the wagon
+at full speed.</p>
+
+<p>When she reached the main road the vehicle
+had already turned into it and was some distance
+away, headed for Paris, at a speed which, slow
+for a horse, was still much faster than she could
+possibly walk.</p>
+
+<p>She looked up and down the road helplessly.
+There were several other wagons approaching,
+all going in the same direction&mdash;cityward. She<span class='pagenum'><a name="Page_202" id="Page_202">[202]</a></span>
+realized that they were country people, farmers,
+taking their vegetables and flowers to the markets.</p>
+
+<p>The first one to reach her was driven by a
+buxom-looking young woman, wearing a plaid
+shawl. Grace hailed her. "Will you be so good,
+Madame, as to take me to Paris?"</p>
+
+<p>The woman glanced at her shrewdly. "I have
+a heavy load, Mademoiselle," she replied. Her
+voice was cold, uninterested.</p>
+
+<p>"I will pay you five francs&mdash;"</p>
+
+<p>The words had barely left Grace's lips, before
+the woman had pulled up her horse. "Five
+francs, Mademoiselle? That is another matter.
+Get in."</p>
+
+<p>Grace clambered up beside the woman and
+glanced down the road ahead. The canvas-covered
+wagon was still in sight&mdash;mounting a hill
+some three or four hundred yards ahead.</p>
+
+<p>The woman looked at her curiously, noting
+her dress, her hands, her shoes. "You are not
+of the country, Mademoiselle," she remarked,
+pleasantly.</p>
+
+<p>"No. I belong in Paris." She turned to her
+companion. "I should like to return there as
+quickly as possible."</p>
+
+<p><span class='pagenum'><a name="Page_203" id="Page_203">[203]</a></span>"My Susette does not care to go above a walk,"
+the woman remarked, gazing at her horse, plodding
+along with mechanical steps, as though utterly
+unconcerned as to whether or not they ever
+reached Paris. The wagon ahead was now out
+of sight, over the brow of the hill.</p>
+
+<p>"Would you like to make a louis?" Grace
+took a gold piece from her purse and held it in
+the sunlight. It glistened brightly.</p>
+
+<p>The woman drew back, regarding her companion
+suspiciously. "A louis? Who would not?
+What do you mean, Mademoiselle?"</p>
+
+<p>"There is a wagon ahead of us, a canvas-covered
+wagon, with a white horse. I am following
+it. If you will keep that wagon in sight until
+we get to Paris, I will give you this louis."</p>
+
+<p>She turned the gold piece about, making it
+sparkle in the sun. The woman glanced first
+at her face, then more carefully at the coin, then,
+reaching over, took it in her fingers, and raised
+it to her mouth. Grace wondered what she was
+about to do. In a moment she had sunk her teeth
+into it, then returned it to her companion. "It
+shall be as you say, Mademoiselle," she exclaimed
+as she pulled in the reins. "Allons, Susette!"</p>
+
+<p>The horse, evidently awakened from his morning<span class='pagenum'><a name="Page_204" id="Page_204">[204]</a></span>
+dreams, started forward with a suddenness
+which almost precipitated Grace from her seat.
+The trees along the roadside began to fly past
+them. In ten minutes they were close behind
+the canvas-covered wagon, now moving along at
+a brisk pace.</p>
+
+<p>When they reached the fortifications, the two
+wagons were separated by not more than a dozen
+feet. Grace's companion glanced at her sharply.
+"From here I go to Grennelle, Mademoiselle,"
+she exclaimed.</p>
+
+<p>Grace looked at the wagon ahead. "Follow
+it, please," she said. "I will give you another
+five francs."</p>
+
+<p>The woman obeyed in silence. The wagon in
+front of them headed off toward the northwest,
+going in the direction of Passy. Before a great
+while it crossed the Pont de Passy, turned into
+the Rue Nicolo, and came to a stop before a
+small brick house, standing in a little garden.</p>
+
+<p>Grace jumped down at the corner, after giving
+the woman the louis and the additional five francs.
+"Thank you," she said, and started slowly up the
+street.</p>
+
+<p>The wagon with the canvas cover stood quietly
+alongside the curb. The old man who drove it<span class='pagenum'><a name="Page_205" id="Page_205">[205]</a></span>
+had approached the door of the house, and was
+ringing the bell.</p>
+
+<p>Presently one of the windows on the top floor
+was thrown open, and a man's head was thrust
+out. Grace could not see his face clearly. He
+looked down at the man at the door, who at the
+same time looked up. The window was instantly
+closed, and a few moments later the door of the
+house opened and the man came out.</p>
+
+<p>He stood talking with the driver in low tones
+for a few moments. Grace had walked on up
+the street, fearing to attract attention. Looking
+back, she saw that the two men were gazing after
+her. She dared not turn her head again, but at
+the next corner turned into a cross street. Then
+she stopped, and cautiously peered around the
+corner. The two men had gone to the wagon
+and were lifting out the large basket. A few
+moments later they disappeared with it into the
+house.</p>
+
+<p>After a time, the old man returned with the
+basket in his hands. From the way he carried it
+Grace could see that it was empty. He tossed
+it carelessly into the wagon, mounted the seat,
+and drove off.</p>
+
+<p>Grace looked at her watch. It was half past<span class='pagenum'><a name="Page_206" id="Page_206">[206]</a></span>
+seven. She felt cold and hungry, and determined
+to get something to eat at once. A little pastry
+cook's shop and restaurant on the opposite side
+of the street attracted her attention, and she
+crossed over, entered, and ordered rolls and coffee.
+She could see the windows of the house into
+which the two men had carried the basket, from
+where she sat.</p>
+
+<p>She scarcely knew what to do next. It seemed
+almost certain that Mr. Stapleton's child was in
+the house across the way, and yet&mdash;it was merely
+an intuition, a guess, which might turn out to
+be entirely wrong. Yet she feared to go away,
+not knowing at what moment the child, if he was
+indeed there, might be taken elsewhere, and the
+clue hopelessly lost.</p>
+
+<p>She finished her rolls and coffee, taking as
+much time to consume them as she could. She
+had just made up her mind to go, when the door
+of the house across the street opened, and a man
+came out. He was dark, and heavily built, and
+dressed in the costume affected by artists. He
+headed directly for the pastry shop, and Grace
+realized that he was about to enter it.</p>
+
+<p>She turned her face away, fearing lest he might
+have noticed her, as she walked up the street.<span class='pagenum'><a name="Page_207" id="Page_207">[207]</a></span>
+He did not even glance in her direction, however,
+but went at once to a counter at the rear of the
+place.</p>
+
+<p>The proprietor came up to him with a smile,
+rubbing his hands together cheerily. "Ah!
+Monsieur Durand. Up early this morning, I
+see. What can I do for you?"</p>
+
+<p>She did not catch the other's reply, nor did she
+dare to glance at his face. She shrank back into
+her corner, and, picking up a newspaper which
+lay in the window sill, began to read.</p>
+
+<p>The new customer remained but a few moments.
+When he left, Grace saw that he carried
+a large paper bag with him, which appeared to
+contain rolls or bread.</p>
+
+<p>He again entered the house, but this time remained
+inside but a few moments. A little later
+she left the shop, and watched him as he disappeared
+down the street.</p>
+
+<p>For half an hour she walked about, wondering
+whether she should telephone Monsieur Lefevre
+now, or wait until she had made certain that the
+whole affair was, after all, not a wild goose chase.
+Suddenly she was seized with a new determination.
+She went boldly up to the house, and rang
+the bell.</p>
+
+<p><span class='pagenum'><a name="Page_208" id="Page_208">[208]</a></span>In a few moments a sleepy-looking maid
+opened the door, eying Grace with lazy indifference.</p>
+
+<p>"I wish to see Monsieur Durand," the latter
+said.</p>
+
+<p>"He's out."</p>
+
+<p>"Then I must wait. I am a model. He instructed
+me to come at eight o'clock, and to wait
+until he returned."</p>
+
+<p>The girl shrugged her shoulders, and pointed
+to the stairs. "Top floor front," she grumbled,
+and turned away.</p>
+
+<p>Grace lost no time in getting up the stairs. To
+her surprise, the door of the studio, upon which
+was a card bearing Monsieur Durand's name, was
+unlocked. She pushed her way boldly in, and
+looked about. The room was scantily furnished,
+and contained little besides a couple of modeling
+stands, several large plaster figures and casts, two
+chairs, and a couch, evidently used as a bed. At
+the rear of the room was a closet. She turned
+to it and threw it open. It contained only an
+assortment of clothes.</p>
+
+<p>She felt completely baffled. There was no possible
+place, here, in which the child she was seeking
+could be hidden. Evidently she had been on<span class='pagenum'><a name="Page_209" id="Page_209">[209]</a></span>
+the wrong track. And yet&mdash;what had the wicker
+basket contained?</p>
+
+<p>Suddenly she stopped, quivering with excitement.
+From somewhere in the room&mdash;she could
+not tell where&mdash;there came a low sobbing sound,
+as of a child, crying to itself. It vibrated throughout
+the room, at one moment close to her ears,
+the next far off, intangible, like a whispered
+echo. She stood, listening, every nerve tense with
+excitement, and still that low sobbing went on,
+coming from nowhere, evanescent as a dream.</p>
+
+<p>The thing seemed unreal, horrifying. She
+gazed about helpless. Then she heard the front
+door of the house suddenly slam, followed by the
+sound of heavy footsteps on the stairs.</p>

+<h2>CHAPTER XIV.</h2>
+
+<p class="cap extraspacetop">RICHARD DUVALL rose, the following
+day, with a less troubled mind than at
+any time since his arrival in Paris.</p>
+
+<p>His calculations of the night before had
+brought him to a definite conclusion.</p>
+
+<p>After breakfasting in the caf&eacute; of the hotel he
+returned to his room, and rang up Monsieur
+Lefevre.</p>
+
+<p>"I want the assistance of one of your men,
+Monsieur," he said.</p>
+
+<p>"Ah!" laughed the Prefect. "You are&mdash;what
+you Americans call&mdash;up a tree, is it not?"</p>
+
+<p>"Not at all. You have said that there existed
+between us a competition, to recover Mr. Stapleton's
+child. I think I am going to win. But since
+I am not in a position to make the necessary arrests,
+myself, I am going to share the glory with
+you, my dear friend, by allowing one of your
+men to do so for me."</p>
+
+<p>"So you are confident?"</p>
+
+<p><span class='pagenum'><a name="Page_211" id="Page_211">[211]</a></span>"Reasonably so. Can you spare Vernet for the
+day? He is a good man."</p>
+
+<p>"One of my best. You shall have him. And
+if you succeed, I shall still regard myself the
+loser, and will buy the champagne, and the dinner
+at the Caf&eacute; Royale, as I agreed."</p>
+
+<p>"And I shall be most happy to do the same
+should I fail. Oblige me by requesting Vernet
+to come to my rooms at the hotel at once. Good
+by."</p>
+
+<p>Duvall hung up the receiver, and sat down with
+the drawings he had made before him. He
+awaited the coming of Vernet with impatience.</p>
+
+<p>The latter appeared in some twenty minutes.</p>
+
+<p>"What can I do for you, Monsieur Duvall?"
+he asked.</p>
+
+<p>"Good morning, Vernet. Sit down, and have
+a cigar. I have a little matter I wish to talk over
+with you."</p>
+
+<p>"Concerning the missing child of Monsieur
+Stapleton, I understand," remarked Vernet, as he
+lit a cigar and drew his chair up to the table.
+He glanced at the drawings before him. "What
+are these, may I ask?"</p>
+
+<p>Duvall took up his pencil. "This, Vernet, is a
+map of a small part of Paris. Here, as you see,<span class='pagenum'><a name="Page_212" id="Page_212">[212]</a></span>
+is the Avenue Kleber, terminating at the Champs
+&Eacute;lys&eacute;es just in front of the Arc de Triomphe."</p>
+
+<p>"I see. It is quite plain."</p>
+
+<p>"Here&mdash;this black square&mdash;is Mr. Stapleton's
+house. From there to the arch is a matter of
+some six hundred yards."</p>
+
+<p>"About that, I should say. What of it?"</p>
+
+<p>"Wait. The black-bearded fellow&mdash;the kidnapper&mdash;who
+visited Mr. Stapleton last night,
+and escaped by the ruse of being arrested by one
+of his confederates, will arrive at Mr. Stapleton's
+house at eight o'clock tonight."</p>
+
+<p>"Mon Dieu! If that is so, we have him!"</p>
+
+<p>"Not so fast. We shall not interfere with him&mdash;then."</p>
+
+<p>"But, Monsieur, would you let this fellow escape?
+It is my duty to arrest him, as soon as he
+puts in an appearance."</p>
+
+<p>"You are mistaken, Vernet. Your duty is to
+do as I instruct you. Monsieur Lefevre has
+placed you under my orders for the day."</p>
+
+<p>Vernet laughed. "That is so," he said.
+"What do you wish me to do?"</p>
+
+<p>"The man will come to Mr. Stapleton's house
+at eight o'clock, and will be given a large sum
+of money. He has agreed, if he is not interfered<span class='pagenum'><a name="Page_213" id="Page_213">[213]</a></span>
+with, to have the address where the boy may be
+found telephoned to Mr. Stapleton within half
+an hour."</p>
+
+<p>"Ah! Then we shall follow, and get him after
+he has telephoned."</p>
+
+<p>Duvall laughed. "We are dealing with a far
+shrewder man than that, Vernet. This fellow will
+do no telephoning."</p>
+
+<p>"Then how will he let Monsieur Stapleton
+know?"</p>
+
+<p>"That is just what I am trying to find out. Put
+yourself in his place. He is known&mdash;he dare not
+remain in Paris&mdash;he gets five hundred thousand
+francs to give up the child. Is it not natural to
+suppose that he will leave the city at once?"</p>
+
+<p>"Yes. That is what I should do, in his place."</p>
+
+<p>"Of course. Now I understand that the fellow
+will walk from Mr. Stapleton's house to the Arc
+de Triomphe, a distance of six hundred yards.
+He can do that easily in ten minutes."</p>
+
+<p>"Yes."</p>
+
+<p>"Once at the arch, he will stand awaiting a
+fast automobile, which will come along the
+Champs &Eacute;lys&eacute;es. This automobile will stop for
+an instant and pick him up, then proceed at high
+speed along the Avenue du Bois de Boulogne."</p>
+
+<p><span class='pagenum'><a name="Page_214" id="Page_214">[214]</a></span>"Why do you think that?"</p>
+
+<p>"Because it will afford him the quickest and
+safest road out of Paris. From the arch to the
+Porte Dauphine is less than a mile. He can make
+it in five minutes. In fifteen minutes altogether
+then, he is outside the walls. In another fifteen
+minutes, he is beyond pursuit, in the country."</p>
+
+<p>"But you forget, Monsieur Duvall, that he has
+not yet advised his confederates that all is well,
+and that the address of the place where the boy
+is hidden is to be telephoned to Mr. Stapleton."</p>
+
+<p>"No, Vernet, I haven't forgotten that. In
+fact, I am coming to it now. Suppose you
+were in this fellow's place&mdash;how would you do
+it?"</p>
+
+<p>Vernet scratched his head thoughtfully. "He
+might fire a pistol from the car."</p>
+
+<p>"Too dangerous. The noise of the explosion
+would attract attention. He must work
+silently."</p>
+
+<p>"A wave of the hand, perhaps, to someone
+along the street."</p>
+
+<p>"Also dangerous. This fellow realizes that
+every possible step will be taken to capture not
+only himself, but his confederates. He anticipates,
+no doubt, that the road will be carefully<span class='pagenum'><a name="Page_215" id="Page_215">[215]</a></span>
+watched. Why take chances, and run the risk of
+his confederates, at least, being arrested, when
+there are simpler, easier ways?"</p>
+
+<p>"Such as what?"</p>
+
+<p>"Do you not remember the signal, used on the
+Versailles road, the blue light?"</p>
+
+<p>"Ah! Exactly. He will signal to some one
+in a house along the way."</p>
+
+<p>"That would be easier and safer; but you will
+remember that there are no houses along the
+way&mdash;none, at least, in which a man of this sort
+could have a confederate hidden. But I should
+not say none. There is one, perhaps."</p>
+
+<p>"Indeed, Monsieur. And what house is that?"</p>
+
+<p>"Mr. Stapleton's. Look!" He drew toward
+him the sheet of paper. "Here," he placed the
+point of his pencil upon the black square which
+indicated the location of the banker's residence,
+"is the house. The north window of a room on
+the top floor commands a view of the Avenue
+du Bois de Boulogne, from a point some 500 feet
+west of the Arc de Triomphe, to where it intersects
+the Avenue Malakoff. Beyond there, the
+view is interrupted. In fact, the trees along the
+Avenue du Bois de Boulogne are to some extent
+an obstruction; but at the crossing with the Avenue<span class='pagenum'><a name="Page_216" id="Page_216">[216]</a></span>
+Malakoff there is a wide and uninterrupted
+view."</p>
+
+<p>"But a confederate in Monsieur Stapleton's
+own house?"</p>
+
+<p>"Yes. The chauffeur, Fran&ccedil;ois."</p>
+
+<p>"You astonish me, Monsieur. We have suspected
+the fellow, it is true. The very room of
+which you speak has been searched. We found
+nothing. How do you know that what you say
+is true?"</p>
+
+<p>"Never mind how I know it&mdash;now. The point
+is this&mdash;Fran&ccedil;ois, I fully believe, will be in that
+room, tonight, at eight o'clock, watching carefully
+the automobiles which pass the intersection of the
+Avenue Malakoff&mdash;"</p>
+
+<p>"Not necessarily, Monsieur. We can easily
+prevent it, by placing him under arrest."</p>
+
+<p>"That is exactly what we must <i>not</i> do. Don't
+you see, it is absolutely necessary, for the recovery
+of Mr. Stapleton's child, that the signals
+go through uninterrupted?"</p>
+
+<p>"Of course, I had forgotten that. And these
+signals?"</p>
+
+<p>"Naturally I cannot tell&mdash;yet. I think, however,
+that the automobile for which Fran&ccedil;ois will
+be looking will show a brilliant blue light, while<span class='pagenum'><a name="Page_217" id="Page_217">[217]</a></span>
+crossing the Avenue Malakoff. That is, of
+course, if our friend the kidnapper gets safely
+away, without being pursued."</p>
+
+<p>"And otherwise?"</p>
+
+<p>"I think the light would be red. He can make
+either, very simply, by means of a powerful electric
+searchlight&mdash;one of these pocket affairs, you
+know, fitted with colored glasses."</p>
+
+<p>"You interest me wonderfully, Monsieur Duvall.
+What next?"</p>
+
+<p>"It is, of course, most important that the signal
+given shall be the correct one. There must be
+no interference whatever with this fellow's escape&mdash;<i>up
+to that point</i>."</p>
+
+<p>"Ah&mdash;I begin to see. And what after that?"</p>
+
+<p>"First, let us continue with Fran&ccedil;ois. He will,
+I think, return a blue signal to the man in the
+automobile, to show that he has seen, and understood.
+He has the means to do so all ready, in
+his room."</p>
+
+<p>"And then?"</p>
+
+<p>"He will make, I think, a similar signal from
+his south window to some one who is on watch,
+in the direction of Passy. This second person, who
+no doubt has the child in his care, will then go
+to a telephone, transmit the address of the house<span class='pagenum'><a name="Page_218" id="Page_218">[218]</a></span>
+where the child is hidden, to Mr. Stapleton, and
+quietly depart, to join his confederate in&mdash;say&mdash;Brussels.
+He will run not the slightest risk of
+capture. If, on the other hand, that message
+fails to go through, the address will <i>not</i>
+be telephoned, and the child will probably be
+killed."</p>
+
+<p>Vernet frowned grimly. "It is a remarkable
+plan, Monsieur. These fellows are no bunglers.
+I think, however, that we shall be able to stop
+them."</p>
+
+<p>"How?"</p>
+
+<p>"I will station myself at the Porte Dauphine
+with a fast automobile, a racer. When these fellows
+pass, I will follow them, and overtake
+them."</p>
+
+<p>"An excellent idea, Vernet; but how, may I
+ask, will you know the car, when it passes you?
+There are hundreds of cars on the Avenue du
+Bois de Boulogne, at eight o'clock in the evening."</p>
+
+<p>Vernet laughed. "I confess, Monsieur, you
+have me there."</p>
+
+<p>"Of course you might station a man at the intersection
+of the Avenue Malakoff and the Avenue
+du Bois de Boulogne; but I do not think he<span class='pagenum'><a name="Page_219" id="Page_219">[219]</a></span>
+would be able to see the signal. By placing on
+the end of the searchlight a paper tube, the light
+would be invisible except in the direction in
+which it is pointed&mdash;and that, you will remember,
+is diagonally upward. A man on the sidewalk
+would not see it at all."</p>
+
+<p>"Then, Monsieur, I fail to see that there is
+anything we can do."</p>
+
+<p>"There is one thing, Vernet. You forget the
+answering signal, from the window."</p>
+
+<p>The Frenchman looked at his companion with
+undisguised admiration. "Sacr&eacute;!" he exclaimed.
+"You have a mind, Monsieur Duvall, in a thousand."</p>
+
+<p>"Thanks," answered Duvall, dryly. "Now, my
+idea is, to have you select some point near the
+intersection of the two avenues, from which the
+window in the rear of Mr. Stapleton's house can
+be clearly seen. Station yourself there, tonight,
+with the fastest automobile you can secure. Let
+one man watch the window, another the vehicles
+passing in the Avenue du Bois de Boulogne. The
+moment you see the blue light, start after your
+man. He should be just across the intersection,
+on his way down the Avenue du Bois de Boulogne."</p>
+
+<p><span class='pagenum'><a name="Page_220" id="Page_220">[220]</a></span>Vernet rubbed his hands together with satisfaction.
+"We shall get him&mdash;never fear."</p>
+
+<p>"Of course," said Duvall, slowly, "all this is
+pure assumption on my part, based upon what I
+have discovered in the chauffeur's room. It may
+not turn out as I say, but the chances are fifty to
+one that it will."</p>
+
+<p>"And you, Monsieur? Where will you be?"</p>
+
+<p>"I shall be in the room, with Fran&ccedil;ois. I do
+not propose that <i>he</i> shall escape. And further&mdash;I
+do not know that I am correct, in my assumption
+regarding his signals to Passy. He may go out,
+and send the telephone message himself. In that
+case, I shall follow. Or he may, through some
+unforeseen accident, get the wrong signal, in
+which case I propose to overpower him, and give
+the right one. Suppose we go, now, and take a
+look at the intersection of the Avenue Malakoff
+and the Avenue du Bois de Boulogne, and see
+what arrangements can best be made. Also, if
+Mr. Stapleton is out in his car, we may be able
+to take a few observations from his chauffeur's
+window." He took up his hat, lighted a cigar,
+and led the way to the door.</p>
+
+<p>They drove to the Arc de Triomphe in a cab,
+and, after dismissing it, walked slowly down the<span class='pagenum'><a name="Page_221" id="Page_221">[221]</a></span>
+Avenue du Bois de Boulogne. At the intersection
+with the Avenue Malakoff they stopped and gazed
+about carefully, although in such a way as not
+to attract attention. A brief inspection served
+to confirm all that Duvall had said. It took them
+some little time to locate the window in the rear
+of Mr. Stapleton's house; but after a time they
+managed to do so, and saw that it commanded
+an uninterrupted view of the point where they
+stood.</p>
+
+<p>Vernet was highly satisfied, as they parted. It
+was deemed unnecessary for him to visit the
+chauffeur's room, and thereby run the risk of their
+being seen entering the banker's house together.
+Vernet departed to make his arrangements for
+the evening, strictly cautioned by his companion
+not to let Monsieur Lefevre into his secret. "It
+is a bet," he told Vernet. "I hope we shall succeed
+in winning it."</p>
+
+<p>After his companion had departed, Duvall
+dropped in to see Mr. Stapleton. He learned
+that the banker was out, driving in the Bois with
+Mrs. Stapleton, who, overcome by anxiety and
+grief, had great need of the fresh air to retain
+her health. She was fast breaking down under
+the strain.</p>
+
+<p><span class='pagenum'><a name="Page_222" id="Page_222">[222]</a></span>Duvall went up to have another look at the
+chauffeur's room. He had been unable to get
+a thoroughly clear idea of the view from the
+window, the night before, owing to the darkness.</p>
+
+<p>He found everything as he had left it,&mdash;the
+searchlight on the dresser, the colored glass ornaments
+hanging from their gay ribbons. The
+north window overlooked with perfect clearness
+the intersection of the two avenues, as he and
+Vernet had seen them from below. The other
+window presented a more distant view. Nearby
+roofs and chimneys obstructed it in part; but between
+them could be seen the villas and buildings
+in Passy, smiling in the sunlight. The sight impressed
+Duvall the more strongly with the cleverness
+of the men he sought to arrest. Somewhere
+in all that maze of buildings, that wide vista
+of houses and trees and distant fields, Mr. Stapleton's
+child lay concealed, and it needed but a
+flash of light from this window to set him free.
+Passing his fingers idly along the window sill,
+Duvall suddenly observed two parallel scratches
+in the white paint, which had apparently been
+made with the point of a knife. He knelt down,
+and sighted between them. His line of vision<span class='pagenum'><a name="Page_223" id="Page_223">[223]</a></span>
+swept clear of the nearby roofs and chimneys,
+toward Passy.</p>
+
+<p>The detective turned from the window, a smile
+of satisfaction on his face, and proceeded to make
+a careful examination of the chauffeur's closet.
+It was here that he intended to lie hidden. He
+felt certain that, in order the better to perceive
+and send his signals, as well as to escape detection
+from below, the chauffeur would allow his room to
+remain unlighted.</p>
+
+<p>This, Duvall reasoned, would render it easy
+for him to lie concealed until the signal which
+would insure the safe return of the lost child had
+been given, after which he would call upon
+Fran&ccedil;ois with precision and despatch. Should
+anything occur to prevent the chauffeur from giving
+the favorable signal, he proposed to give it
+himself.</p>
+
+<p>The closet was close to the north window, and
+its door opened in such a way that Duvall saw at
+once that in the darkened room he could readily
+open it sufficiently to see all that Fran&ccedil;ois did,
+without running any serious risk of detection.</p>
+
+<p>He left the house at a little after noon and
+stopped in at a well known restaurant on the
+Boulevard des Italiens for lunch. He felt very<span class='pagenum'><a name="Page_224" id="Page_224">[224]</a></span>
+well satisfied with the course that events were
+taking. If only he could get through with this
+thing, and get back to Grace, and the farm, he
+would be supremely happy. He became so absorbed
+in his thoughts that he failed to notice a
+gentleman who slipped quietly into the chair opposite
+him, until the latter leaned over and
+touched his arm.</p>
+
+<p>He looked up suddenly. It was Monsieur
+Lefevre!</p>

+<p><span class='pagenum'><a name="Page_225" id="Page_225">[225]</a></span></p>
+<h2>CHAPTER XV</h2>
+
+<p class="cap extraspacetop">THE few seconds that elapsed while Grace
+Duvall stood in the deserted studio in
+Passy, waiting for the arrival of the person
+who was ascending the stairs, seemed like
+eternities, so crowded were they with terror.</p>
+
+<p>What should she do&mdash;what, indeed, could she
+do? A dozen plans raced madly through her
+brain, confusing her, baffling her with their
+futility.</p>
+
+<p>That the missing boy was within the sound of
+her voice, she knew; for even as she stood trembling
+at the ominous footsteps on the creaking
+stairs, she could hear the low troubled childish
+moaning, coming apparently from the very air
+in front of her, yet affording not the slightest
+clue as to the boy's whereabouts.</p>
+
+<p>She glanced about the room in desperation.
+Nearer and nearer came the creaking footfalls
+on the stairs. She dared not leave the room now,
+and thereby meet the approaching man face to<span class='pagenum'><a name="Page_226" id="Page_226">[226]</a></span>
+face on the landing; yet to remain where she was
+would result only in her being obliged to make
+some lame and halting excuse for her presence,
+and go, as soon as the man entered the room.</p>
+
+<p>Even this she could not count upon. The fellow,
+no doubt a desperate and unscrupulous ruffian,
+might attack her, might detain her a prisoner
+until the child had been safely removed to
+another place, beyond all hope of discovery. All
+the work of the past twelve hours would come to
+nothing. And even should he let her go, in
+safety, he could not fail to suspect the reasons
+for her presence and warn his companions.</p>
+
+<p>Clearly the only thing to do was to remain in
+the room, in hiding. There was but one place
+in which she could hope to escape instant detection&mdash;the
+closet. Yet even this promised but temporary
+safety; the man would be almost certain
+to open it, for some reason or other, and discover
+her presence.</p>
+
+<p>It was her only chance, however, and she took
+it. Even as the footsteps of the approaching
+man sounded upon the landing outside, Grace
+flew across the room and into the closet, closing
+the door softly behind her. In her haste, one
+arm of a velveteen coat which hung upon a hook,<span class='pagenum'><a name="Page_227" id="Page_227">[227]</a></span>
+became jammed in the door, with the result that
+it would not entirely close. She realized that it
+was too late to remedy the trouble now, and
+crouched back trembling with excitement.</p>
+
+<p>The jamming of the door had caused it to remain
+slightly open, with a space half an inch
+broad between it and the casing. Through this,
+Grace could see a part of the room before her.
+She watched the door to the hallway intently, as
+it was thrown open.</p>
+
+<p>The man she had seen in the pastry shop came
+in, several packages in his hands. These he
+placed upon a table, and at once began to prepare
+breakfast. A small alcohol lamp served for
+coffee, and butter, rolls, and fruit he produced
+from the paper bags before him. There was
+also a bottle of milk. Grace wondered if this
+was intended for the child.</p>
+
+<p>The man went about his preparations silently.
+Grace occasionally obtained a good view of his
+face. He was apparently about thirty years of
+age, dark and swarthy. There was something familiar
+about his manner, his general appearance;
+although what it was, she could not tell. She was
+certain, however, that she had seen him before.</p>
+
+<p>Once or twice he made a move, as though<span class='pagenum'><a name="Page_228" id="Page_228">[228]</a></span>
+to approach the closet; but each time it
+was something else that claimed his attention.
+Once it was to get a package of cigarettes that
+lay upon one of the modeling stands. Grace wondered
+what she would have done, had he kept on
+toward her, and opened the closet door.</p>
+
+<p>She fell to thinking, in momentary snatches,
+about home, and Richard. How curious it seemed
+for them both to be here in Paris, separated for
+all these days, yet so near each other! She wondered
+if Richard had written to her, and what
+he would think, not to have heard from her.
+Then she remembered that after all he had been
+in Paris but a few days&mdash;there was scarcely time
+for a letter to have reached him. She thought
+of Uncle Abe, pottering about among the flower
+beds, of Aunt Lucy grumbling good naturedly
+over her wash tubs, of Rose, singing her queer
+camp meeting songs in the spring twilight, of
+Don, and the other dogs, the chickens, and her
+beloved flowers, and wondered how all of them
+were getting along with Richard and herself both
+away.</p>
+
+<p>Her reveries were interrupted by a sudden
+sound which made her start forward, tense with
+excitement. The man in the studio had gone for<span class='pagenum'><a name="Page_229" id="Page_229">[229]</a></span>
+a moment beyond the line of her vision, into a
+corner of the room to her left. She could not
+see what he was doing there, and it was while
+waiting for him to reappear that she had fallen
+into her day dream.</p>
+
+<p>The sound which startled her was the voice
+of a child, not crying, this time, but speaking
+clearly and distinctly. "I want to go home!" it
+said, in a high nervous voice. "I want to see my
+mamma!"</p>
+
+<p>The man answered roughly, impatiently. "You
+can't go now. Be quiet and come and eat your
+breakfast."</p>
+
+<p>He appeared suddenly in the line of view commanded
+by the crack in the door, and Grace saw
+that he held a small boy by one hand, and was
+leading him to the table. Here he placed him in
+a chair and set before him a glass of milk and
+a roll. "Hurry up now!" the man growled. "Eat
+your breakfast. I've got to go out."</p>
+
+<p>The man's words set Grace's heart to beating
+with renewed quickness. If the man was going
+out, she would be able to escape, and take the
+boy with her.</p>
+
+<p>She did not doubt that he was Mr. Stapleton's
+child. The girl's dress which he had worn on<span class='pagenum'><a name="Page_230" id="Page_230">[230]</a></span>
+the former occasion had been removed, and in
+place of it he wore a suit of dark blue, somewhat
+dirty and worn. His face still appeared to be
+very dark, and his hair, which had formerly been
+long and curly, was cropped close to his head.
+He appeared to be well, but very nervous. Grace
+watched him eagerly as he devoured the roll and
+milk.</p>
+
+<p>When he had finished, the man took him by
+the hand and again led him to the corner of the
+room beyond Grace's sight. She strained her
+face against the opening in the door, striving
+in vain to see what he was doing; but it was useless.</p>
+
+<p>She heard the boy begin to object, begging the
+man in a querulous voice to let him go out and
+play. His captor, however, silenced him with a
+sharp word, accompanied by a blow. "Get in
+there, and keep quiet!" Grace heard him say, and
+after that all was silent. A moment later the
+man reappeared, put on his hat, and, going out,
+locked the door carefully behind him. Grace
+wondered if the maid had told him of her call,
+and thereby roused his suspicions.</p>
+
+<p>She waited until she heard the front door close,
+and then, emerging quickly from the closet, went<span class='pagenum'><a name="Page_231" id="Page_231">[231]</a></span>
+toward the side of the room to which the man
+had gone with the child.</p>
+
+<p>At first sight, there appeared to be no place
+where the latter could have been hidden. The
+two walls were of gray-tinted plaster, cracked and
+stained with age. There was a rickety chair and
+a battered plaster figure of a centaur, against
+which leaned an easel and a mass of sketches,
+covered with cobwebs and dust.</p>
+
+<p>With extreme care, she examined the walls and
+floor. It seemed most likely that some trapdoor
+existed, affording an entrance to a secret closet
+in which the boy had been placed. A few moments'
+effort showed no traces whatever of such
+a hiding place. The floor was of planks, covered
+with dust, and the cracks between the boards were
+filled with dirt and showed nowhere evidences of
+having been recently moved. The walls she
+sounded gently with the handle of a modeling
+tool which she snatched up from the
+table; but they gave forth a uniformly solid
+sound.</p>
+
+<p>She stood, surveying the place in perplexity.
+Then a sudden thought occurred to her. The
+ceiling! It swept low down, at the corner of the
+room, and above it she knew there must be an<span class='pagenum'><a name="Page_232" id="Page_232">[232]</a></span>
+attic. She went over and began to examine the
+dusty plaster surface with minute care.</p>
+
+<p>A sound of footsteps upon the stairs sent her
+scurrying back into the closet. She wondered
+why the man had returned so soon. Greatly to
+her surprise, she saw, as soon as the door opened,
+that the newcomer was not the one who had left
+her a short time before, but an older man, more
+heavily built. As he turned and glanced toward
+the side of the room where she was hidden, she
+saw that he wore a heavy black beard. It was
+the kidnapper himself&mdash;the man whom she had
+seen at Mr. Stapleton's house the night before!</p>
+
+<p>He appeared to be annoyed, at not finding anyone
+in the studio, and after a moment sat down
+and lighting a cigar, began to read a newspaper
+which he drew from his pocket.</p>
+
+<p>Grace watched him intently, hardly daring to
+breathe for fear he might hear her. An hour
+passed, and the air in the closet became close and
+hot. She felt so nervous that she could have
+screamed, when the door of the room suddenly
+opened and Durand appeared.</p>
+
+<p>The two greeted each other with a nod.
+"Where have you been?" the older man demanded,
+somewhat angrily.</p>
+
+<p><span class='pagenum'><a name="Page_233" id="Page_233">[233]</a></span>"I had to get a new battery." He took a short
+black cylinder from his pocket and laid it on the
+table.</p>
+
+<p>"Is the boy here?"</p>
+
+<p>"Yes."</p>
+
+<p>"Good! Now listen to your instructions." He
+lowered his voice, glancing swiftly toward the
+closed door of the room. "At eight o'clock I
+shall go to the banker's house and get the money.
+At eight fifteen, or a little before, Fran&ccedil;ois will
+get his signal and repeat to you. If he flashes
+the blue light, you will release the boy, leave the
+room, lock the door, and go at once to the Place
+du Trocadero. From the little tobacco shop you
+will telephone the address of this place&mdash;No.
+42, isn't it?&mdash;to Monsieur Stapleton. That will
+be about half past eight. Do not telephone before
+that. Then wait for me in front of the shop.
+Do you understand?"</p>
+
+<p>"Perfectly. And if I get the red signal?"</p>
+
+<p>"In that event, do not release the boy, but
+lock the door and come to the tobacco shop, as
+before. I will communicate with you there. Old
+Martelle is perfectly safe. But I do not think
+there will be any trouble. You will get the blue
+light."</p>
+
+<p><span class='pagenum'><a name="Page_234" id="Page_234">[234]</a></span>"You seem sure."</p>
+
+<p>"I am. This man Stapleton is not going to
+take any more chances. Once I am in the automobile,
+I am safe."</p>
+
+<p>"They could arrest you while you are walking
+to the Arc de Triomphe, after leaving the
+house."</p>
+
+<p>"That is true; but what would they gain. They
+would not get the boy, would they? And they
+have no evidence to show that I stole him. Further,
+Fran&ccedil;ois reports this morning that he overheard
+Stapleton and his wife talking. There is
+to be no interference&mdash;at least not until I get
+away in the machine. They will follow me, of
+course. I fully expect it. But you know the steps
+I have taken to take care of <i>that</i> game." He
+laughed grimly. "No&mdash;no&mdash;the thing is absolutely
+safe. We will get away without the least
+trouble."</p>
+
+<p>"Nevertheless, if anything goes wrong, and I
+do not get the red signal, what shall we do then?"</p>
+
+<p>"We'll talk that over, when the time comes.
+You meet me at Martelle's."</p>
+
+<p>"But suppose you can't be there? They might
+get you, you know."</p>
+
+<p>The man with the beard frowned darkly, and<span class='pagenum'><a name="Page_235" id="Page_235">[235]</a></span>
+an evil expression came over his face. "If you get
+the red signal, and I do not meet you at Martelle's
+at half past eight, come back here, get
+the boy, and take him to Lavillac. And before
+you do so, cut off his left hand, and send it to
+Stapleton with a letter telling him that if I am
+not set free at once, you will send his head. That
+will bring them to terms."</p>
+
+<p>Grace shuddered as she heard the man's words.</p>
+
+<p>His companion nodded. "I understand," he
+said. "But I hope it won't be necessary."</p>
+
+<p>"It won't. They can't get me. I've planned
+too carefully. That American detective, Duvall,
+is a joke. He was out on the Boulevard du Bois
+de Boulogne this morning with one of the Prefect's
+men. They are figuring to have an automobile
+at the Avenue Malakoff and follow me."
+He laughed loudly. "Much good that will do
+them!"</p>
+
+<p>"How about Fran&ccedil;ois?"</p>
+
+<p>"Oh&mdash;in a week or two, after we are safely
+away, Fran&ccedil;ois will sprain his wrist, and be forced
+to give up his position as Monsieur Stapleton's
+chauffeur. He will join us in New York."</p>
+
+<p>The younger man puffed meditatively at his
+cigarette. "What's become of that woman Lefevre<span class='pagenum'><a name="Page_236" id="Page_236">[236]</a></span>
+had snooping around? Seen anything of
+her, since last night?"</p>
+
+<p>"No. She hasn't been about. Not much danger
+of <i>her</i> finding out anything."</p>
+
+<p>The other rubbed his chin, in deep thought.
+"She nearly got you, last night," he presently
+remarked.</p>
+
+<p>"Oh, no. Not a chance. I knew she was in
+the house, and I figured she would telephone to
+headquarters as soon as she learned who I was.
+All I had to do was to signal you, through the
+window, and the thing was done. Of course I
+didn't expect the Prefect's man to get there quite
+as soon as he did; but you handled him all right."
+As he spoke, the man rose, went to a small mirror
+that hung on the wall, and carefully removed
+the black beard which was so distinguishing a
+feature of his appearance.</p>
+
+<p>"Pretty hot, this thing," he announced, as he
+threw it on the table. "Got anything to drink
+about? I'm thirsty."</p>
+
+<p>Grace saw, as he turned toward her, that he
+bore a striking resemblance to the masked man
+who had given her the first message to Mr.
+Stapleton, in the room of the house on the road
+to Versailles. She trembled as she heard him ask<span class='pagenum'><a name="Page_237" id="Page_237">[237]</a></span>
+for the drink. Suppose the bottle should be in
+the closet? She shrunk back in terror as the
+younger man rose and started toward her.</p>
+
+<p>Her alarm was needless, however. The fellow
+drew open one of the drawers of a small dresser
+that stood on the opposite side of the room, and
+took out a light green bottle. "Absinthe?" he
+inquired.</p>
+
+<p>"All right. One won't do any harm. Don't
+take any more, though." He began to pour out
+the drink into a glass which stood upon the table.
+"When you get the signal from Fran&ccedil;ois," he
+went on, "you are to answer it, as usual, so he'll
+know you've seen him. He doesn't want to stay
+in his room very long&mdash;for fear he might be
+missed."</p>
+
+<p>"They suspect him, of course."</p>
+
+<p>"Yes. He's being watched right along; when
+he's out of the house, that is. They've searched
+his room, and all that; but they haven't found
+anything." He chuckled, and began to sip his
+drink. "Nothing to find."</p>
+
+<p>The other man sat down at the table, and the
+two began talking over their plans of escape.
+Grace could not hear all they said; but, as nearly
+as she could gather, they intended, as soon as the<span class='pagenum'><a name="Page_238" id="Page_238">[238]</a></span>
+younger man had joined the other, to run for
+Brussels in the automobile. Near the frontier
+they would leave the machine, change their disguises,
+and cross the frontier on foot. Once in
+Belgium, they seemed to think they would be quite
+safe.</p>
+
+<p>It was along toward noon when the older man
+readjusted his disguise and left the house. "I'm
+going to get something to eat," he announced. "I
+won't be back. You'd better not leave the place
+again. I'll send you in something, if you like."
+He glanced at the rolls and milk on the table.</p>
+
+<p>"It won't be necessary. I've got all I need.
+Guess I'll take a nap this afternoon. Well, good
+luck," he concluded, as the other started toward
+the door. "See you later."</p>
+
+<p>"All right." The black-bearded man passed
+noiselessly into the hall. "Don't sleep too long.
+Eight o'clock, remember." In a moment he was
+gone.</p>
+
+<p>Grace watched the other as he finished drinking
+his absinthe and lit a cigarette. Presently he went
+over to the cot and, throwing himself upon it, was
+soon snoring loudly.</p>
+
+<p>The long hot afternoon wore itself on. Grace
+leaned back against the wall of the closet, weak<span class='pagenum'><a name="Page_239" id="Page_239">[239]</a></span>
+from the nervous tension of the situation. The
+place was hot and close. She felt faint from lack
+of air, from hunger. At times she dozed off,
+then recovered herself with a start, and stood
+trembling, fearful lest she had made some noise
+which might attract the attention of the sleeping
+man.</p>
+
+<p>After a time, the low complaining of the child
+began again, at first faint and seemingly far off,
+then growing in volume, until the tearful cries of
+"Let me out&mdash;let me out!" seemed to come from
+a point scarcely beyond the reach of her hand.</p>
+
+<p>The child's complaints at last awoke the sleeping
+man. With a muttered curse he rose, crossed
+the room, and disappeared from sight. Grace
+heard a low scraping sound, as of a panel being
+drawn back, and presently the man again appeared
+with the child, and again supplied him with
+bread and milk.</p>
+
+<p>After he had eaten, the man gave him a magazine
+with bright-colored pictures in it, to amuse
+him, and lay on the bed, smoking. The boy sat
+on the floor, looking at the book.</p>
+
+<p>Once or twice he tried to speak, but the man
+sharply bade him be quiet. About sundown, a
+step was heard on the stairs, and once again the<span class='pagenum'><a name="Page_240" id="Page_240">[240]</a></span>
+boy was hastily placed in his hiding place, with
+threats of punishment if he cried.</p>
+
+<p>The new arrival was only a model, in search of
+work. The man spoke to her gruffly, and informed
+her that he had all the models he needed.
+After she left, he did not again release the child,
+but sat, reading, for a long time.</p>
+
+<p>At last he rose, took up the short black cylinder,
+which Grace saw was an electric searchlight, from
+the table, and went over and sat in the sill of
+the large double window which faced to the north.
+The window was open, and the room in darkness.</p>
+
+<p>Grace pushed the door of her closet open
+slightly, so as to get a better view. The window
+was directly opposite the closet, at the other end
+of the room. She could see the silent figure of
+the watcher, silhouetted blackly against the night
+sky without. Off to the north were many lights&mdash;the
+lights of the houses toward the Champs &Eacute;lys&eacute;es,
+and the Arc de Triomphe.</p>
+
+<p>For many minutes she watched, over the man's
+shoulder, waiting for the signal which would set
+both herself and Mr. Stapleton's boy free from
+their long confinement.</p>
+
+<p>Presently she heard the man utter a quick oath,
+and saw him peer out of the window, his figure<span class='pagenum'><a name="Page_241" id="Page_241">[241]</a></span>
+tense and rigid, a pair of field glasses held to
+his eyes. In another moment he had dropped
+the glasses, picked up his electric searchlight, and
+flashed a signal into the darkness.</p>
+
+<p>It took him but a moment. In another he had
+rushed to the door, and Grace heard him turn
+the key in the lock and clatter down the stairs.</p>
+
+<p>She crept swiftly to the window and looked out.
+At first she could see nothing, but a confused maze
+of lights. In a moment she had seized the field
+glasses and was nervously sweeping the horizon.
+Suddenly she held them still for a moment, then
+drew back with a cry of dismay. Far off toward
+the Avenue Kleber there gleamed a light, high in
+the upper room of a house. It shone for a few
+moments, steady, baleful, full of unknown terror,
+then winked suddenly out and was gone. She
+dropped the field glasses upon the floor and staggered
+back against the table. <i>The light was red!</i>
+She was locked in. The two men would undoubtedly
+be back in fifteen or twenty minutes. And
+then&mdash;she shuddered as she thought of what they
+intended to do to the kidnapped child. To herself
+she gave scarcely a thought. Then Richard's
+face came before her eyes, and she fell upon the
+window seat, sobbing bitterly.</p>

+<h2>CHAPTER XVI</h2>
+
+<p class="cap extraspacetop">WHEN Monsieur Lefevre touched Richard
+Duvall on the shoulder, in the
+restaurant in the Boulevard des Italiens,
+he was filled with a very great feeling of anxiety,
+although he concealed it behind a mask of pleased
+surprise at the unexpected meeting.</p>
+
+<p>Since early the evening before he had had no
+word from Grace. He knew from Mr. Stapleton
+that she had left his house a short while after
+nine; but since then she had completely disappeared.</p>
+
+<p>The Prefect at first thought that she had been
+unable to keep her identity from her husband any
+longer, and had joined him. He later learned
+from Vernet that this was not the case. Now the
+old gentleman began to feel seriously alarmed at
+her continued absence.</p>
+
+<p>"How goes everything, my friend?" he asked,
+with an elaborate show of carelessness. "Have
+you found the kidnappers yet?"</p>
+
+<p><span class='pagenum'><a name="Page_243" id="Page_243">[243]</a></span>Duvall smiled. "Not yet. But I expect to
+have them, before the evening is over."</p>
+
+<p>"Indeed! I congratulate you. Have you seen
+anything of Mademoiselle Goncourt?"</p>
+
+<p>"No. Why?"</p>
+
+<p>"I thought perhaps you might have met her.
+You two are after the same game, you know."</p>
+
+<p>Duvall smiled grimly. "I don't believe she's
+following the same trail that I am," he said. "I
+expect to win that bet, Monsieur."</p>
+
+<p>The Prefect seemed a trifle uneasy. "The evening
+is not yet over, Monsieur," he replied. "But,
+in any event, I hope that Monsieur Stapleton's son
+will be returned to him without further delay,
+whoever brings about the result."</p>
+
+<p>"Come to his house tonight, Monsieur. I have
+arranged a little matter with Vernet which may
+surprise you. And then, too, we shall have to go
+and get the boy." He rose, and took up his hat.
+"We shall want you with us."</p>
+
+<p>"By all means. I shall be there, my friend.
+What hour would you suggest?"</p>
+
+<p>"Half past eight, at the latest."</p>
+
+<p>"Good! I shall be there at that time. Good
+day, <i>mon ami</i>."</p>
+
+<p>"Au revoir. Give my respects to Mademoiselle<span class='pagenum'><a name="Page_244" id="Page_244">[244]</a></span>
+Goncourt." He left the restaurant and, going to
+his room at the hotel, proceeded to write a long
+letter to Grace. He reproached her for not having
+written to him. Here he had been in Paris
+four days, and had not heard a word from her!
+A letter, he felt, should have come by the very
+next steamer&mdash;several, in fact. He told her how
+greatly he missed her, how deeply he loved her,
+and how soon he hoped to return to her arms.
+And even as he wrote, Grace, half dead from
+fatigue, stood hidden in the closet at Passy, a mile
+away, watching with frightened eyes the kidnapper
+asleep on the pallet bed.</p>
+
+<p>Duvall had arranged to be at Mr. Stapleton's
+house a little before eight that night, and it still
+lacked twenty minutes of the hour when he ascended
+the steps of the banker's residence and was
+ushered into the library.</p>
+
+<p>Mr. Stapleton sat in grim silence, awaiting the
+coming of his visitor. He did not seem particularly
+glad to see Duvall. The latter's apparent
+failure to make any headway in the matter of
+recovering his missing boy had caused the banker
+to lose confidence in his abilities.</p>
+
+<p>"Good evening, Duvall," he remarked, indifferently.</p>
+
+<p><span class='pagenum'><a name="Page_245" id="Page_245">[245]</a></span>"Good evening, Mr. Stapleton. You are ready
+for your man, I see." He glanced at the package
+of banknotes which lay at the banker's elbow.</p>
+
+<p>"Quite. You have done nothing to interfere
+with his coming or going, I trust."</p>
+
+<p>"Nothing."</p>
+
+<p>Stapleton glanced at the clock. "He will be
+here very soon, now. May I ask you to wait in
+my study, upstairs? It would never do for you
+to be here. The man might be afraid to enter."</p>
+
+<p>"No&mdash;you are right. I must not be here. But
+I prefer not to wait in the study. I have another
+plan."</p>
+
+<p>"What is it?" inquired the banker, uneasily.</p>
+
+<p>"Where is Fran&ccedil;ois, your chauffeur?"</p>
+
+<p>"At his dinner, I believe. Why?"</p>
+
+<p>"Will you kindly find out for sure? I want to
+go to his room."</p>
+
+<p>Mr. Stapleton summoned a servant, who told
+him that the chauffeur was just finishing his dinner.
+"You will be very careful, Duvall," he said,
+anxiously. "I don't want anything done which
+will alarm these fellows."</p>
+
+<p>"Oh, Fran&ccedil;ois won't see me. I shall keep
+out of his sight. Perhaps I had better go up
+now." He nodded to the banker, and at once<span class='pagenum'><a name="Page_246" id="Page_246">[246]</a></span>
+ascended the stairs which lead to the servants'
+quarters.</p>
+
+<p>At the door of the chauffeur's room he paused.
+It was closed. He pushed it gently open, and in
+a moment was in the room. The place was quite
+dark; but by means of a pocket light Duvall soon
+found the closet, and a moment later was safely
+ensconced within. He left the door ajar, and to
+his satisfaction found that he could see through
+the north window without difficulty. Here he
+waited, until the chauffeur should arrive.</p>
+
+<p>Mr. Stapleton, meanwhile, sat grimly in the
+library below, waiting for the coming of the kidnapper.
+Promptly at eight o'clock, his butler
+announced that the man had arrived.</p>
+
+<p>"Show him in at once," exclaimed the banker,
+as he rose and began to walk up and down the
+room.</p>
+
+<p>In a moment the man came into the library.
+His powerful figure, his black beard, his assured
+manner, rendered him an easily recognized figure.</p>
+
+<p>"I have come, Monsieur, as I said I would,"
+he remarked, calmly. "I trust you have the
+money in readiness."</p>
+
+<p>Stapleton stepped over to the desk and picked
+up the package of banknotes. "Here it is," he<span class='pagenum'><a name="Page_247" id="Page_247">[247]</a></span>
+growled. "I understand that you will, in return
+for this money, send me word at once as to where
+my son is to be found."</p>
+
+<p>"Within half an hour, Monsieur, at the latest;
+provided, of course, I am not interfered with in
+my escape."</p>
+
+<p>"There will be no interference, until I get back
+my boy. After that, I shall spend another hundred
+thousand dollars, if need be, to bring you to
+justice."</p>
+
+<p>"That, Monsieur, is quite within the terms of
+our agreement. The moment you receive the address,
+you are free from any obligation to me.
+May I see the money?" He extended his
+hand.</p>
+
+<p>Mr. Stapleton placed the banknotes in it.
+"Count them," he growled, "and assure yourself
+that you have received the amount you demand."</p>
+
+<p>The kidnapper sat down with the utmost coolness
+and began to count over the notes. They
+were all of large denomination, and the operation
+consumed but a few moments. As soon as he had
+finished, the man placed the bundle of notes carefully
+in an inside pocket and rose. "The amount
+is correct, Monsieur," he said. "Permit me to
+bid you a very good evening." Without further<span class='pagenum'><a name="Page_248" id="Page_248">[248]</a></span>
+delay, he bowed, took up his hat, and left the
+room.</p>
+
+<p>At the door he glanced quickly at his watch,
+then strode off up the street at a rapid pace,
+toward the Arc de Triomphe.</p>
+
+<p>For some eight or ten minutes he walked, at
+the expiration of which time he arrived at the
+Place de l'&Eacute;toile, and at once crossed to
+the pavement surrounding the great triumphal
+arch.</p>
+
+<p>Up and down the twelve great avenues which
+radiate from the Place of the Star flashed innumerable
+automobiles, coming and going like huge
+jeweled fireflies.</p>
+
+<p>The kidnapper paused at a point on the very
+outer edge of the circular pavement which surrounds
+the arch, and waited, expectant, his eyes
+fixed upon the broad sweep of the Champs
+&Eacute;lys&eacute;es.</p>
+
+<p>For some moments he stood thus, rigid, motionless.
+Suddenly a big black racing car swept
+from the line of traffic and approached the curb.
+The man on the sidewalk raised his hand, and
+made a momentary gesture. The car quivered
+to the side of the street, pausing but the fraction
+of a second as the tall figure of the kidnapper<span class='pagenum'><a name="Page_249" id="Page_249">[249]</a></span>
+stepped in. Another moment, and it had swept
+around the great arch and was flying down the
+Avenue du Bois de Boulogne.</p>
+
+<p>Close behind it came a second car, which, like
+the first, contained but a single occupant in addition
+to the chauffeur. With scarcely fifty feet
+between them, the two machines swept down the
+broad street toward the intersection with the
+Avenue Malakoff.</p>
+
+<p>In a few moments, both had reached it. But
+here their ways parted. The first car, turning in
+a quick and dangerous quadrant, swept into the
+Avenue Malakoff and sped southward like the
+wind. The second car continued on toward the
+Porte Dauphine. As it passed the intersection
+with the Avenue Malakoff, the chauffeur, unobserved
+by his passenger, directed a cylindrical
+black object toward the southern sky and held it
+there, motionless, until his car had disappeared
+in the shadow of the trees to the west.</p>
+
+<p>Just inside the Avenue Malakoff lay a third
+car, its powerful engine shaking it from end to
+end with its rapid pulsations. Two men sat in
+the tonneau. One of them was occupied in watching
+a distant window in the rear of a house on
+the Avenue Kleber with a pair of field glasses.<span class='pagenum'><a name="Page_250" id="Page_250">[250]</a></span>
+The other kept his gaze fixed upon the road before
+him.</p>
+
+<p>Suddenly the man with the field glasses turned,
+and pointed toward the car which was just passing
+from sight along the Avenue du Bois de Boulogne.
+"Quick!" he muttered. "After him!"</p>
+
+<p>The automobile shot forward like a racehorse
+under the whip, and in a moment was flying down
+the avenue in hot pursuit.</p>
+
+<p>The foremost car was making high speed; but
+the one which pursued it was clearly the faster of
+the two. Slowly the space which separated them
+began to decrease. The man in the first car spoke
+quietly to his chauffeur, and the great car jumped
+forward with renewed speed.</p>
+
+<p>Vernet, in charge of the pursuing car, swore
+softly to himself as he saw his quarry pull away
+from him. He had confidence, however, in the
+speed of his own machine, and urged his driver to
+greater efforts.</p>
+
+<p>For several miles the two swept on, the rear
+car gaining slowly, in spite of the other's best
+efforts. They had passed the fortifications and
+were now in the Bois de Boulogne, and with
+clearer roads ahead the chase seemed likely to be
+a long one.</p>
+
+<p><span class='pagenum'><a name="Page_251" id="Page_251">[251]</a></span>Suddenly, to Vernet's astonishment, the forward
+car began to slow up. In a moment the Prefect's
+men ranged alongside, and covered the solitary
+passenger with their revolvers.</p>
+
+<p>"Surrender!" Vernet cried. "You are my
+prisoner."</p>
+
+<p>The man in the other car looked up, and calmly
+began to light a cigarette. "Are you a bandit,
+my friend?" he inquired, calmly.</p>
+
+<p>The detective was taken aback. The two cars
+had now come to a standstill at one side of the
+road. "Search him!" he said quickly to his companion.</p>
+
+<p>The second man climbed into the car. Its occupant
+made no protest. "What do you wish with
+me, gentlemen?" he asked, with a sarcastic smile.
+"My watch&mdash;my money?"</p>
+
+<p>"The searchlight, first of all," replied the detective,
+"with which you signaled."</p>
+
+<p>The man looked at him in astonishment.
+"What are you talking about, Monsieur?" he
+inquired. "Is this then a joke?"</p>
+
+<p>Vernet began to feel a trifle uneasy. This man
+certainly did not appear to resemble in any way
+the prisoner he had sought. He was a clean-shaven
+young man, elegantly dressed, and quite<span class='pagenum'><a name="Page_252" id="Page_252">[252]</a></span>
+evidently a gentleman. "Do you deny," asked
+the detective, "that on passing the Avenue Malakoff
+a few moments ago you flashed a blue light
+toward the Avenue Kleber?"</p>
+
+<p>The young man laughed. "Of course I deny
+it," he said. "Why the devil should I be flashing
+blue lights at the Avenue Kleber? And who are
+you, to ask me any such nonsensical questions?"</p>
+
+<p>"I am an agent of the police, Monsieur. Who
+are you?"</p>
+
+<p>"I am Anton Lemaitre, stock broker, of the
+firm of Lemaitre and Bossard." He handed a
+card to the dumbfounded Vernet. "I am trying
+a new automobile, which I think of purchasing.
+My chauffeur proposed that we try it out in the
+Bois, where there is more opportunity to speed
+than in the city."</p>
+
+<p>"Why did you then run away?"</p>
+
+<p>"My dear sir, I saw you following me. I
+wish to own a fast car&mdash;the fastest car in Paris,
+if possible. I directed my driver to see what he
+could do. I do not believe, however, that I
+shall now buy the car, since yours is faster. What
+make is it, Monsieur, if I may ask?"</p>
+
+<p>Vernet smothered an oath. Clearly this man
+was telling the truth. He directed his companion<span class='pagenum'><a name="Page_253" id="Page_253">[253]</a></span>
+to get in with Monsieur Lemaitre. "Drive to the
+Prefecture," he said, "and let the gentleman tell
+his story to Monsieur Lefevre." He himself
+ordered his chauffeur to proceed with all despatch
+to Mr. Stapleton's house. The affair had ended
+in a fiasco. He felt that he must see Duvall at
+once.</p>
+
+<p>In fifteen minutes he was at the house. Mr.
+Stapleton was waiting patiently in the library for
+the telephone call which would announce the hiding
+place of his boy. With him were Mrs. Stapleton
+and Monsieur Lefevre.</p>
+
+<p>The poor man and his wife were in a pitiable
+state, their eyes glued to the clock which stood on
+the mantel. It was marked twenty-six minutes
+past eight. "Only four minutes more!" gasped
+Mrs. Stapleton, through her tears. "My God!
+why don't they hurry?"</p>
+
+<p>Her husband endeavored to console her.
+"They may be a few moments late, my dear.
+Don't excite yourself. I am sure they will keep
+their word."</p>
+
+<p>Vernet went over to Monsieur Lefevre and
+explained the events of the evening in a few
+words. The Prefect smiled grimly. "So Monsieur
+Duvall has failed again!" he remarked, in<span class='pagenum'><a name="Page_254" id="Page_254">[254]</a></span>
+a low voice. "Mon Dieu! If we do not soon
+hear from Mademoiselle Goncourt, I shall begin
+to feel nervous myself."</p>
+
+<p>Slowly the hands of the clock crept around.
+As the half hour was reached, and the telephone
+bell remained silent, Mrs. Stapleton uttered a
+groan of despair, and sank upon the couch, weeping
+pitifully. Mr. Stapleton, watch in hand, paced
+up and down the room. "They have been interfered
+with," he stormed, "or they would have
+communicated with me before now!" He turned
+to Monsieur Lefevre. "You have done nothing,
+I hope, to again prevent me from recovering my
+son?"</p>
+
+<p>"Nothing, Monsieur."</p>
+
+<p>Mr. Stapleton waited another five minutes. It
+now wanted twenty minutes to nine. The telephone
+bell remained persistently silent. The banker
+closed his watch with a snap and thrust it into
+his pocket. His face was pale with rage and
+suffering. Drops of perspiration collected on his
+forehead. "The scoundrels!" he cried. "They
+have broken their word, and robbed me of a hundred
+thousand dollars in the bargain. I will give
+another hundred thousand to the man who will
+capture them, dead or alive, and find my boy!"</p>
+
+<p><span class='pagenum'><a name="Page_255" id="Page_255">[255]</a></span>There was a profound silence, broken only by
+the quick sobbing of Mrs. Stapleton. Neither
+Lefevre nor Vernet ventured to speak.</p>
+
+<p>Suddenly there arose sounds of a commotion
+among the servants gathered in the hall without.
+In their devotion to their employer they had collected
+there to welcome the lost boy. There were
+exclamations, cries of astonishment&mdash;and dismay.</p>
+
+<p>The occupants of the room turned in surprise
+toward the door. As they did so, Richard Duvall
+appeared in the doorway. He staggered, and
+with difficulty supported himself by clutching the
+side of the door. His face was covered with
+blood, his clothes torn and disheveled.</p>
+
+<p>He swayed a moment, unsteadily in the door.</p>
+
+<p>"What is it&mdash;what is wrong?" cried Stapleton,
+starting toward him.</p>
+
+<p>"The child is at 42 Rue Nicolo, Passy," gasped
+the detective, then fell heavily upon the library
+floor.</p>
+
+<hr class="r15" />
+<p><span class='pagenum'><a name="Page_256" id="Page_256">[256]</a></span></p>
+<h2>CHAPTER XVII</h2>
+
+<p class="cap extraspacetop">RICHARD DUVALL, waiting with nervous
+impatience in the closet in Fran&ccedil;ois' room,
+at last heard a soft and guarded step
+upon the stairs. He drew back, his muscles tense,
+and gazed fixedly at the door.</p>
+
+<p>Although the room was dark, the glow of the
+street lamps from without, the faint light of the
+evening sky, sufficed, now that his eyes had become
+accustomed to the darkness, to enable him not
+only to recognize the chauffeur as he entered the
+room, but to follow his movements with little or
+no difficulty.</p>
+
+<p>The man seemed hurried. He groped his way
+to the dresser at the opposite side of the room,
+and felt about for the searchlight which Duvall
+knew lay within easy reach.</p>
+
+<p>Having secured it, he directed it for a brief
+moment upon his watch, noted the time, then,
+going to the door, opened it, and began to listen
+intently.</p>
+
+<p><span class='pagenum'><a name="Page_257" id="Page_257">[257]</a></span>The detective at once surmised that he was
+listening for the departure of his confederate, the
+man with the black beard.</p>
+
+<p>Presently the chauffeur drew back, closing the
+door with a grunt of satisfaction, and once more
+approached the dresser. Duvall concluded that
+he had gone to get the colored glasses by which
+he would be able to make the required signals.</p>
+
+<p>In a moment he returned to the window, and
+Duvall saw him place the two glass cups upon the
+sill, and lean out expectantly.</p>
+
+<p>It seemed a long time before he stirred. The
+detective, looking over his shoulder, found that
+his line of vision was interrupted so that he could
+not see the lights which flashed past the entrance
+of the Avenue Malakoff. He was forced to content
+himself with keeping a close watch upon the
+chauffeur.</p>
+
+<p>Suddenly the man, by an almost instantaneous
+movement, clapped one of the little glass cups
+over the end of the tube which formed the searchlight,
+and directed it toward the street. Duvall
+could not tell whether the signal was blue, or red.
+He had every reason to believe, however, that
+it was the former.</p>
+
+<p>The chauffeur held the tube upon the window<span class='pagenum'><a name="Page_258" id="Page_258">[258]</a></span>
+sill for a few seconds only, then withdrew it, and
+started to cross the room toward the south window.
+As he did so, he swept the light into the
+room, and for an instant it fell upon the crack
+in the closet door through which Duvall was
+peering. He was conscious of a blinding blue
+radiance, close to his eyes, and the sudden flash
+caused him to draw back with a quick and involuntary
+movement. He realized that the chauffeur
+had not seen him, and that, in a few moments
+more, the signal would be given which would
+bring untold happiness to both Mr. Stapleton and
+his wife.</p>
+
+<p>The momentary recoil, however, was fatal to
+his plans. Although he moved his head but a
+fraction of an inch, the suddenness of the movement
+was sufficient to cause a metal coat hanger,
+which hung, empty, from a hook, to click sharply
+against its neighbor.</p>
+
+<p>The chauffeur spun around with the quickness
+of a cat, and, grasping the knob of the closet door,
+threw it open. In his hand he still clutched the
+tube of the searchlight.</p>
+
+<p>Duvall at the same moment reached for the
+revolver which lay in a side pocket of his coat.
+He realized instantly that, now that his presence<span class='pagenum'><a name="Page_259" id="Page_259">[259]</a></span>
+had been discovered, the chauffeur would of course
+not send the signal to his confederates in Passy
+which would result in the telephoning of the address
+to Mr. Stapleton, but would on the contrary
+flash a red signal, which the detective fully
+believed would result in the child's death.</p>
+
+<p>It was imperative that this should be prevented.
+Duvall had determined to be present in the chauffeur's
+room for two reasons,&mdash;first, to send
+the favorable signal to Passy himself, should
+things go wrong, and the chauffeur receive a
+red flash from the street; secondly, to arrest
+Fran&ccedil;ois in the act of receiving and sending the
+signals.</p>
+
+<p>He now realized that he must do both, and
+that, too, without a moment's delay.</p>
+
+<p>As the chauffeur threw open the door he flashed
+the blue light full upon the crouching figure of the
+detective.</p>
+
+<p>The latter, revolver in hand, commanded him
+sharply to throw up his hands.</p>
+
+<p>The chauffeur did so&mdash;thereby directing the
+light of the electric lamp toward the ceiling. The
+sudden change from the glare which an instant
+before had been in his eyes, to almost total darkness,
+left Duvall momentarily blind. His eyes<span class='pagenum'><a name="Page_260" id="Page_260">[260]</a></span>
+could not instantaneously respond to the withdrawal
+of the light. The figure of the chauffeur
+appeared but a dark and formless shadow.</p>
+
+<p>The latter, however, not having faced the glare
+of the light, was able to see without difficulty.
+With lightning like quickness he spun around on
+one foot, until his back instead of his face was
+toward the detective. Then his right foot rose,
+in the famous and deadly blow of the <i>savate</i>.</p>
+
+<p>It has been said that this backward kick, so
+dear to the heart of the Parisian crook, is more
+to be feared than any possible onslaught in good
+old Anglo-Saxon style with the fists. Certainly
+in this instance it was too much for Richard Duvall.
+The unexpected blow, coming during the
+moment when the sudden darkness had left him
+blinded and confused, sent him crashing back into
+the depths of the closet, buried beneath a
+mass of clothing. His arms, entangled in falling
+coats and waistcoats, were helpless. The
+revolver flew from his hand, and lay useless on the
+floor.</p>
+
+<p>The chauffeur went about his business calmly.
+His first move was to direct the searchlight carefully
+into the interior of the closet, slipping the
+blue cup from the end of it as he did so and allowing<span class='pagenum'><a name="Page_261" id="Page_261">[261]</a></span>
+it to fall unheeded to the floor. His second
+was to draw a long and peculiarly deadly looking
+knife.</p>
+
+<p>His quick eye saw at once that the revolver was
+no longer in the detective's grasp. His searchlight
+enabled him to discern it, lying on the floor
+to one side of the closet. Before Duvall could
+extricate himself from the articles of clothing in
+which he was entangled, Fran&ccedil;ois had stooped
+quickly, picked up the revolver, and slammed the
+door of the closet upon him. As he struggled
+to his feet, the detective heard the click of the
+key as it turned in the lock. He was a
+prisoner.</p>
+
+<p>Without losing a moment, the chauffeur tossed
+the revolver upon the table, took up the cup-shaped
+bit of red glass, fitted it to the tube of the
+searchlight, and, going to the south window, placed
+it upon the sill in such a way that its crimson glare
+was directed almost due south. It was evident
+that the position in which the light was placed was
+marked by the two tiny scratches cut in the woodwork
+of the window sill. In a moment he had
+turned back toward the closet door.</p>
+
+<p>Duvall, meanwhile, realized that only by instant
+and superhuman effort could he hope to<span class='pagenum'><a name="Page_262" id="Page_262">[262]</a></span>
+remedy the frightful situation which his unlucky
+movement had precipitated.</p>
+
+<p>He braced his shoulders and back against the
+rear wall of the closet, put his two feet against
+the door, and with every atom of strength in his
+body strove to force it open.</p>
+
+<p>His movements had been quick. Just as the
+chauffeur turned back from the window toward
+the room, Duvall, his muscles knotted with effort,
+drove the full force of his body against the closet
+door.</p>
+
+<p>The lock, a cheap affair, was torn loose in a
+twinkling, and an instant later the two men had
+grappled in the center of the room.</p>
+
+<p>The detective's one desire was to get to the
+window, remove the red light which he knew was
+flashing its fateful message across the housetops,
+and substitute for it a blue light, which he hoped
+even now might shine forth in time to redeem the
+situation.</p>
+
+<p>This, however, the chauffeur was equally determined
+to prevent. He realized that he was caught,
+that his complicity in the affair was known,
+and that he must warn his comrades of his danger,
+so that, by refusing to give up the boy, they
+might effect his release. He was fighting for his<span class='pagenum'><a name="Page_263" id="Page_263">[263]</a></span>
+liberty as desperately as Duvall was fighting for
+that of Mr. Stapleton's child.</p>
+
+<p>The two men were evenly matched. The chauffeur
+was perhaps the stronger, in shoulders and
+arms, due to his profession. The constant grip
+upon the steering wheel had given to his upper
+body muscles like steel.</p>
+
+<p>The detective, though somewhat less powerful
+in this direction, was stronger in the back and
+legs. He had been an athlete, at college, and his
+recent life upon the farm at home had toughened
+and hardened him from head to foot.</p>
+
+<p>He rushed at his opponent, threw his arms
+around the latter's waist, and strove to lift him
+and throw him to the floor.</p>
+
+<p>The chauffeur at the same time got his right
+arm about Duvall's throat, and with his left did
+his best to gouge out one of the latter's eyes. His
+was the style of fighting that considers not means,
+but results.</p>
+
+<p>For a moment they swayed heavily about the
+room, the detective burying his face in his opponent's
+side to protect his eyes, and at the same time
+striving with all his might to force him back
+toward the bed.</p>
+
+<p>Fran&ccedil;ois, however, fought well. He began to<span class='pagenum'><a name="Page_264" id="Page_264">[264]</a></span>
+compress his adversary's throat in a choking grip
+of wrist and forearm which threatened to put
+an end to the struggle in short order. At the same
+time his left thumb continually sought the detective's
+eyes.</p>
+
+<p>Suddenly it reached one of them. Duvall felt
+a blinding sense of pain as the thumb nail sank
+into the soft and tender muscles about the eye.
+The shock was fatal to the plans of the chauffeur;
+for it raised up in his opponent a great and deadly
+rage, that for an instant gave him the strength of
+a madman. He raised his opponent from the
+floor as though the latter had been a child, broke
+the grip upon his throat by straightening his head,
+and with a mighty heave hurled him to the floor.</p>
+
+<p>The fellow struck upon his side, his temple
+crashing loudly against the wooden floor. Duvall
+stood over him for an instant, breathing heavily,
+convulsively, then turned and snatched the
+searchlight from the window sill and threw it
+upon the bed.</p>
+
+<p>There was a trunk against the wall of the
+room, near the window, and about it a broad
+leather strap. Duvall tore the strap from its place,
+and in a few moments had fastened it about the
+chauffeur's arms and body.</p>
+
+<p><span class='pagenum'><a name="Page_265" id="Page_265">[265]</a></span>A towel, knotted about his ankles, rendered
+him helpless. Then the detective began to search
+upon the floor for the bit of blue glass.</p>
+
+<p>In his heart there was no joy at the victory
+he had just won. He had captured one of the
+kidnappers, it was true; but on the other hand
+he had, by his own carelessness, prevented the
+safe return of the kidnapped boy to his parents.</p>
+
+<p>He pictured the father and mother, patiently
+waiting below for the telephone message which
+would never come, and wondered how he would
+dare to tell them the truth.</p>
+
+<p>At last his nervous fingers closed upon the little
+glass cup, where it had rolled under the edge of
+the dresser when Fran&ccedil;ois had thrown it down.
+Trembling with haste, he fixed it to the searchlight
+which he took from the bed, and, with a hopeless
+feeling, approached the window, and began
+to wave the light frantically in the direction of
+Passy.</p>
+
+<p>For several moments there was no response.
+As a matter of fact, he scarcely expected any.
+Then all of a sudden he saw a faint red gleam,
+like a star, flash from the distant night, and then
+go out.</p>
+
+<p>He stood, helpless, waiting for it to reappear,<span class='pagenum'><a name="Page_266" id="Page_266">[266]</a></span>
+hardly daring to hope that it would do so. Suddenly
+it shone again, this time for a longer period,
+and then disappeared. He wondered what it
+meant, and was scarcely surprised when the light
+again flashed, this time making five quick flashes,
+which he instantly recognized as Morse code for
+the letter "P." There was a brief interval, then
+once more the signals began to flash. This time
+he read them without difficulty. There were four
+letters, spelling the word "Help."</p>
+
+<p>For an instant he leveled the tube of the
+searchlight toward the point from which the
+flashes came, guiding it by the scratches on the
+sill, and began pressing the button which turned
+the light on and off. "Where are you?" he spelled
+out, then waited fearfully for the reply. He
+dared send no other message. The person at the
+other end, the one who sent this ominous word,
+"help," must be one of the kidnappers; yet why
+should he signal for assistance? He could make
+nothing of the matter, but he reasoned that anyone
+calling for help would be sure to give their location,
+otherwise how could they expect to receive it.</p>
+
+<p>For a moment the red flashes began again,
+and this time he began to get the numbers.
+There were four quick flashes and a long dash,<span class='pagenum'><a name="Page_267" id="Page_267">[267]</a></span>
+then others in rapid succession: "4-2-R-u-e-N-i-c-o-l-o,
+P-a-s-s-y," the message read. "C-o-m-e
+q-u-i-c-k."</p>
+
+<p>Duvall's head reeled, as he spelled out the
+words. He had not realized until now that he
+was wounded. The blood, pouring down his face
+from the great gash in his cheek, spattered thickly
+upon the window sill. He turned from the window,
+then realized that he must send some answer,
+to let this mysterious person at the other end of
+the line know that his message had been safely
+received.</p>
+
+<p>"Will come at once. Who are you?" he spelled
+out, laboriously, his head spinning, his fingers
+trembling from weakness as he tried to stop the
+flow of blood from his wound.</p>
+
+<p>"G-R-A-C-E D-U-V-A-L-L" came back the
+flashes, quick, clear cut, unmistakable.</p>
+
+<p>Duvall dropped the searchlight to the floor
+with a harsh laugh. His brain was reeling&mdash;the
+whole thing became a foolish, senseless nightmare.
+He wondered if he was delirious, and had
+dreamed it all. Again he flashed a signal into the
+darkness. "Who are you?" he spelled out again.
+He did not believe that he had read the former
+answer aright. Evidently his imagination was<span class='pagenum'><a name="Page_268" id="Page_268">[268]</a></span>
+playing him tricks&mdash;Grace had been on his mind
+so constantly, throughout the day. He wiped the
+blood from his eyes and stared eagerly out into
+the darkness. There was no response.</p>
+
+<p>Then he remembered the words of the message,
+"Come quick." There was no time for idle
+speculations as to the identity of the person who
+had sent him the message.</p>
+
+<p>He rushed to the stairs, and with tottering footsteps
+descended to the library below. Fran&ccedil;ois,
+the chauffeur, still lay, bound and unconscious,
+upon the floor.</p>

+<p><span class='pagenum'><a name="Page_269" id="Page_269">[269]</a></span></p>
+<h2>CHAPTER XVIII</h2>
+
+<p class="cap extraspacetop">FOR a few moments after being left alone
+in the studio at Passy, Grace almost lost
+her courage. She knew that the man who
+had remained on guard in the room had received
+the danger signal&mdash;the red light&mdash;which told him
+that the plans of his confederates had miscarried.
+She remembered the instructions which the black-bearded
+man had given him. "If I do not meet
+you at Martelle's, take the boy to Lavillac. And
+before you do so, cut off his left hand and send it
+to Mr. Stapleton."</p>
+
+<p>The very thought of the thing made her sick.
+She rushed to the door, and tore frantically at
+the knob; but it resisted all her efforts. She
+glanced at the windows, knowing that to escape
+by means of them from her position on the top
+floor of the house was impossible. And then&mdash;should
+she escape, she would be obliged to leave
+the child, and this she by no means wanted to do.</p>
+
+<p><span class='pagenum'><a name="Page_270" id="Page_270">[270]</a></span>Suddenly she heard again the faint moaning.
+The sound almost drove her frantic. She rushed
+to the window and looked out, praying for guidance,
+for some ray of hope in the frightful situation
+in which she found herself.</p>
+
+<p>Already several minutes had passed since the
+departure of the man. It would not be long, she
+felt, before he returned, and, for all she knew, the
+black-bearded man with him. Would they attack
+her, if they found her there? She could hide
+again, of course; but that would not accomplish
+anything, except perhaps, to save herself. And
+she had set out to rescue the child.</p>
+
+<p>In a whirl of indecision, she glanced out of the
+window, toward the point in the north where she
+had seen the red light. She wondered where it
+was, from what place it had been sent. Then
+suddenly, as she swept the horizon with eager
+eyes, she saw, where a few moments before the
+red light had flashed, a gleam of blue. Unlike
+the red signal, however, which had been steady,
+as though fixed in place, this one moved about
+restlessly, now pointing full at her, now almost
+disappearing to the right or left.</p>
+
+<p>She seized the field glasses and gazed at the
+light in wonder. Did this mean that the kidnappers<span class='pagenum'><a name="Page_271" id="Page_271">[271]</a></span>
+had been successful, after all, and that the
+former signal had been a mistake, or did it indicate
+that the person giving the first signal had
+been overpowered, and that the light was in the
+hands of friends?</p>
+
+<p>She had no means of knowing; but here was
+someone who was trying to send her word that all
+was well. She determined to reply.</p>
+
+<p>Her one thought was to get to Mr. Stapleton
+her present address. She knew that the man who
+had been intrusted with the task of telephoning it
+to the banker, would not now do so. She would
+try to send the address herself.</p>
+
+<p>Then came to her a great feeling of joy, that
+she was familiar with the Morse code. Richard
+had taught it to her, during their trip from Paris
+to New York the year before. She remembered
+how she had been interested in the wireless,
+and Richard had offered to teach her the
+alphabet.</p>
+
+<p>She picked up the searchlight and examined it.
+It was an ordinary pocket lamp, with a dry battery,
+such as are sold at stores dealing in electrical
+goods, and she saw, from its size, that it was an
+unusually powerful one.</p>
+
+<p>Midway along one side was a tiny button, by<span class='pagenum'><a name="Page_272" id="Page_272">[272]</a></span>
+pressing which the circuit was completed, and
+the light made to flash. By pressing this button
+momentarily, she could get a quick flash, comparable
+to a dot. By holding it down longer, she
+could produce a dash.</p>
+
+<p>She did not stop to remove the red glass which
+was fixed over the front of the light; in fact, she
+concluded that it would be better to let it remain.
+There were many white lights all about&mdash;among
+them, her own would have but a small chance
+of being seen. But red was significant, conspicuous,
+indicative of danger, and that she was in
+grave danger she very well knew.</p>
+
+<p>She decided to first send the word "help." She
+knew that if the person receiving the message was
+a friend, he would at once ask where she was,
+since that would be to Mr. Stapleton and his party
+the most essential and important news she could
+give.</p>
+
+<p>On the other hand, were it to be received by
+one of the kidnappers, he would ask her, not
+where she was, but what was the matter.</p>
+
+<p>Painfully, fearful of mistakes, she deciphered
+the message which slowly flashed across the mile
+of night. "Where are you."</p>
+
+<div class="figcenter extraspacetop" >
+<img src="images/illus03a.jpg" width="355" height="546" alt="With trembling fingers she spelled out her reply, giving the address and

+<p class="center caption blockquote">With trembling fingers she spelled out her reply, giving the address and
+adding, &quot;Come quick!&quot;</p>
+
+<p><span class='pagenum'><a name="Page_273" id="Page_273">[273]</a></span></p>
+<p class="extraspacetop">With trembling fingers, she spelled out her
+reply, giving the address and adding, "Come
+quick." When she got the answer, "Will come
+at once," she felt that there was still a chance
+that the boy might be saved. Then came the request
+for her name. She gave this impatiently.
+What difference did it matter, so long as they
+came quickly.</p>
+
+<p>She hastily lighted a candle which stood upon
+the table, then cast about her for some means
+whereby she might prevent the black-bearded man
+and his companion from entering the room, in
+case they should return before help arrived.
+There was one thing, of course, that she could
+do, barricade the door.</p>
+
+<p>But, with the exception of the table and the
+light iron bed, there was nothing with which she
+could hope to secure it. Suddenly her eyes fell
+upon the great plaster centaur. It was a figure
+such as one might see in any art gallery or museum.
+It stood upon a plaster slab some six inches
+thick, which in turn rested upon a low wooden
+base. The figure was at least five feet high&mdash;a
+horse with a human torso and head. She knew
+that if she could jam this in front of the door,
+securing it in place with the bed and table, she
+might prevent the kidnappers from entering for<span class='pagenum'><a name="Page_274" id="Page_274">[274]</a></span>
+some little time; long enough, she hoped, to insure
+the arrival of the police before they had
+succeeded in breaking in.</p>
+
+<p>She wondered if she could manage to move
+the thing. At first sight, it seemed impossible, and
+yet the base might by chance be fitted with rollers
+or casters. She rushed over to the figure and
+began to tug at it with all her strength.</p>
+
+<p>She needed but a moment to discover that she
+could not possibly move it; but as she bent over it,
+her head close to its side, she heard something
+which made her start with sudden joy.</p>
+
+<p>It was the low sobbing of a child&mdash;the same
+moaning sound which she had heard from time
+to time ever since she had first entered the room.</p>
+
+<p>At times the sound had appeared to come from
+afar off; at others, it had seemed to be close at
+hand, as though originating at some point in the
+very air about her.</p>
+
+<p>All of a sudden the truth came to her like a
+flash. The child was concealed within the hollow
+body of the statue. The thing seemed so simple,
+so apparent, that she wondered that it had not
+occurred to her before.</p>
+
+<p>She gave up her attempt to barricade the door,
+and began feverishly to look for the opening in<span class='pagenum'><a name="Page_275" id="Page_275">[275]</a></span>
+the plaster cast through which the child must have
+entered.</p>
+
+<p>It took but a few moments to find it. The
+whole side of the horse's body had been sawed
+free, by two longitudinal cuts, one along the back,
+the other along the belly, and two similar cuts,
+at the shoulder, and the flank. Heavy strips of
+canvas, glued across the lower cut, on the under
+side of the horse's belly, served as hinges, and
+were not visible from above.</p>
+
+<p>She inserted the blade of a modeling tool
+which she caught up from the table, in the upper
+longitudinal cut, and pried the plaster side of the
+horse free. It fell heavily toward her, disclosing
+a long narrow opening; the interior, in fact, of
+the statue, where lay, upon a sort of bed made of
+an old comfort, the missing son of Mr. Stapleton.</p>
+
+<p>The boy, who had evidently until a moment
+before been asleep, gazed up at her in surprised
+alarm. For over two weeks, now, he had been
+kept from his parents, made to move about from
+place to place, frightened by strange men. He
+had come to expect the unusual, the terrifying,
+and it was a scared little face that looked appealingly
+up at the girl as she bent over him.</p>
+
+<p>For the time being she forgot the dangers which<span class='pagenum'><a name="Page_276" id="Page_276">[276]</a></span>
+surrounded them, in her joy at the discovery of
+the boy. It had come so suddenly, so unexpectedly.
+If she could only escape, now, with the
+child, nothing else would matter in the least. And
+between her and freedom there lay but the thickness
+of a single door, and yet it seemed that she
+could not pass it.</p>
+
+<p>She lifted the child from his hiding place and
+stood him upon the floor, then quickly swung the
+heavy slab of plaster back into position. At least,
+she reasoned, the kidnappers, when they returned,
+should not at once learn that their captive had
+escaped.</p>
+
+<p>She knew that the hiding place had been but a
+temporary one, a means whereby the child might
+be kept out of sight during the day in case
+strangers should happen to enter the room. As
+soon as the kidnappers returned, they would, she
+realized, spirit the child away to some more secure
+retreat.</p>
+
+<p>She went to the door and again shook it frantically,
+pulling at the knob with all her strength,
+without producing the slightest result. The lock
+was evidently a strong one&mdash;the door held firm
+and unyielding, though she threw against it her
+entire weight.</p>
+
+<p><span class='pagenum'><a name="Page_277" id="Page_277">[277]</a></span>Evidently there was no hope of escape here.
+Then she again bethought herself of the window.
+For a moment she gazed out into the darkness.
+The pavement was thirty feet below. No one
+was in sight. How could she ever reach the
+ground, with the child as well, even if she had
+possessed a rope? The thing was impossible.</p>
+
+<p>Clearly there was nothing to do but wait. Possibly
+the assistance she expected from her friends,
+or the police, would arrive very soon&mdash;surely she
+could in some way keep the kidnappers occupied
+until then!</p>
+
+<p>And suddenly she realized that the time had
+come. She heard the door of the house close
+softly, and upon the stair the sound of mounting
+footsteps.</p>
+
+<p>Which was it, the police, or the kidnappers?
+The latter, she felt morally certain, since the former,
+in their haste to rescue the child, would
+beyond any question have arrived in an automobile,
+and at top speed.</p>
+
+<p>The newcomers were mounting the stairs in a
+leisurely manner, as though free from any anxiety.
+Grace heard them pause for a moment on the
+first landing, then start up the second flight of
+stairs. It seemed to her out of the question, to<span class='pagenum'><a name="Page_278" id="Page_278">[278]</a></span>
+stand in the middle of the room and await their
+entrance. At least she could postpone the fatal
+moment a little while, by hiding, with the boy,
+in the closet. She stepped into it, the child's hand
+in hers, and drew the door shut, just as the two
+men entered the room. On her way, she hastily
+blew out the candle.</p>
+
+<p>They were the same two men that she had seen
+before,&mdash;the black-bearded man, now without his
+beard, and the artist, Durand. She saw this, as
+soon as the latter had relit the candle. She wondered
+if he would notice that the wick was still
+warm. Evidently he did not; for they threw
+themselves into chairs, lit cigarettes, and began to
+talk.</p>
+
+<p>"Now we can speak freely," said Durand.
+"How did things go?"</p>
+
+<p>"I got the money&mdash;gave the blue signal, and
+expected to be halfway to Brussels by now. What
+nonsense is this about a red light?"</p>
+
+<p>"It is no nonsense, I assure you. I saw it with
+my own eyes, as plain as day."</p>
+
+<p>"Then Fran&ccedil;ois must have made a mistake, or
+else he has been placed under arrest&mdash;the latter,
+no doubt. Now the question is, What shall we
+do? I think we ought to get out of Paris as soon<span class='pagenum'><a name="Page_279" id="Page_279">[279]</a></span>
+as possible. It isn't safe to stay here." He looked
+about him nervously.</p>
+
+<p>"Why not? You didn't telephone Monsieur
+Stapleton this address, did you?"</p>
+
+<p>"No, naturally not."</p>
+
+<p>"Then I don't see but what we are quite safe.
+No one knows the child is here."</p>
+
+<p>"Then you don't intend to give him up?"</p>
+
+<p>"Not yet. I must first find out whether or not
+Fran&ccedil;ois is in trouble."</p>
+
+<p>"Let him look out for himself."</p>
+
+<p>The older man frowned. "Since when, my
+friend," he asked, "have I been in the habit of
+deserting my comrades? Fran&ccedil;ois must go free,
+or Mr. Stapleton does not get his boy. That's
+flat. The first thing is to send his father something
+that will let him see that we mean business."</p>
+
+<p>"We've got to be sure about Fran&ccedil;ois, first."</p>
+
+<p>"I'll find that out, tonight. My plan is this.
+We must first get the child away to Lavillac's
+place. This is too unsafe, here. Anyone might
+come in."</p>
+
+<p>"They'd have difficulty in finding the hiding
+place." The younger man grinned.</p>
+
+<p>"That's all very well; but the other place is<span class='pagenum'><a name="Page_280" id="Page_280">[280]</a></span>
+safer. And then&mdash;Lavillac's woman can look
+after the brat while we are away. What a pity
+Fran&ccedil;ois had to get into a mess at the last moment!
+I hoped to be rid of the boy, by now."
+The older man rose and began striding up and
+down the room.</p>
+
+<p>"Well," he said at length, sharply, "we might
+as well get along. I move that we wrap the boy
+in a coat, take him down to the car, run quickly
+out to Lavillac's place, leave him there, and start
+for Brussels at once. The rest we can do by
+'phone. Fran&ccedil;ois set free&mdash;the boy the same.
+Meanwhile, we've got to show this man Stapleton
+we mean business; so we'd better arrange to send
+him one of the kid's hands at once. If we don't,
+he'll have the whole Paris police force after
+us."</p>
+
+<p>"All right. I'll get him out." He strode
+quickly over to the statue, pulled out the side, and
+gazed blankly into the empty space before him.</p>
+
+<p>"Sacr&eacute;! The child's gone!" he exclaimed, excitedly.
+"Somebody has been here&mdash;in this room&mdash;since
+I left it, half an hour ago."</p>
+
+<p>"The door was locked."</p>
+
+<p>"I know; but somebody's been here, nevertheless,
+for the child is gone."</p>
+
+<p><span class='pagenum'><a name="Page_281" id="Page_281">[281]</a></span>"He may not be gone, Durand. It is true that
+he is no longer in the house; but he may be in
+the room, for all that. Search the closet."</p>
+
+<p>The man named Durand stepped quickly to
+the closet door. "Not much chance," he
+grumbled. "And if the police knew that he was
+here, and have spirited him away, they may even
+now be waiting to spring a trap of which you and
+I are the rats. For all we know the place is
+surrounded at this very moment."</p>
+
+<p>"Then the sooner we get away from it the better.
+Search the closet. If he's not there, we'd
+better make tracks for the frontier as quickly as
+possible. We can do nothing more without the
+child. Fran&ccedil;ois will have to look out for himself."</p>
+
+<p>Durand went impatiently up to the closet
+door and flung it open, then both he and his companion
+recoiled in surprise as Grace stepped out,
+holding the child by the hand.</p>
+
+<p>"Mon Dieu!" gasped the two men in unison.</p>
+
+<p>The one who had worn the black beard was
+the first to recover himself. "Quick!" he cried,
+motioning toward Grace. "The woman is a detective.
+Tie her up, and let's get away at once.
+No doubt she has sent word to her friends. We<span class='pagenum'><a name="Page_282" id="Page_282">[282]</a></span>
+can't afford to stay here another minute." He
+seemed greatly excited and, rushing to the window,
+inspected the silent street below.</p>
+
+<p>Durand, meanwhile, had thrown himself upon
+the girl, seized her hands, and with a quick motion
+had secured them with a bit of cord he snatched
+from within the closet.</p>
+
+<p>She offered no resistance, made no outcry.
+Both seemed equally useless. The boy stood by,
+watching the scene in childish wonder. So many
+queer things had happened to him, however, during
+the past few days, that he, too, remained
+silent.</p>
+
+<p>In a moment the older man withdrew his head
+from the window, rushed to the closet, and drawing
+out a long gray coat, wrapped it about the
+child. "You will come along with us, Mademoiselle,"
+he said sternly. "Make no attempt to
+escape, if you value your life."</p>
+
+<p>"But what do we want with her?" the
+younger man asked, impatiently.</p>
+
+<p>"You fool! Would you leave her here, to give
+our description to the police? It would mean
+certain capture in a few hours. This woman has
+got to be put where she can do no harm until we
+are safely over the frontier. It may be wiser to<span class='pagenum'><a name="Page_283" id="Page_283">[283]</a></span>
+silence her altogether. We'll decide about that
+when we reach Lavillac's. The first thing is to
+get out of this house without losing a moment's
+time. Come!" He started for the door.</p>
+
+<p>As he did so, Grace heard, far off, the steady
+throbbing of an automobile. She felt a wave of
+hope sweep over her. It might be her friends,
+coming to her assistance. If so, they might yet
+arrive in time.</p>
+
+<p>The two men evidently also heard the sound.
+"Hurry&mdash;hurry!" the older one urged, as they
+began to descend the stairs. "They may be on
+us at any moment. Go out the rear way."</p>
+
+<p>Grace heard the sounds of the approaching
+automobile growing more and more distinct. In
+another minute it would stop before the door of
+the house. But in that minute her captors would
+not only have been able to descend the stairs, but
+would already be making good their escape
+through the garden at the rear of the building.</p>
+
+<p>She must do something, she knew, to prevent
+this; but what&mdash;what? Bound as she was, how
+could she hope to prevent the escape of these men.
+She looked ahead of her, to where, a step or two
+in advance, the man of the black beard was
+hastily descending the stairs, the boy firmly held<span class='pagenum'><a name="Page_284" id="Page_284">[284]</a></span>
+in his arms. Behind her came his companion,
+candle in hand, close at her heels.</p>
+
+<p>They were within half a dozen steps of the
+lower hall. From this she could see a dark passageway,
+leading to the rear of the house.
+Already the noise of the automobile without told
+her that it was stopping at the door. She heard
+the sound of rapid footsteps on the sidewalk; yet
+realized that, before her friends could break in,
+their quarry would have flown.</p>
+
+<p>Without a moment's hesitation she sprang forward,
+throwing her whole weight upon the man
+in front of her.</p>
+
+<p>The sudden shock, as she precipitated herself
+upon his shoulders, threw him off his balance, and
+he pitched forward headlong into the hallway
+below. The two of them, together with the
+child, rolled in a tangled heap to the floor. The
+second man, candle in hand, stopped on the stairs
+and gazed helplessly down, not realizing for a
+moment what had happened.</p>
+
+<p>"Help! Help!" Grace screamed at the top of
+her voice, as she struggled to regain her feet, and
+at the same moment there came the sound of
+heavy blows upon the front door.</p>
+
+<p>The man who had been carrying the child rose<span class='pagenum'><a name="Page_285" id="Page_285">[285]</a></span>
+to his feet with an oath, just as his companion
+joined him. He turned on Grace with a howl
+of fury, and struck her a quick blow in the face.
+She had a confused vision of fleeing men, the
+dancing light of a candle, a rush of fresh air, and
+then all was blotted out in a wave of oblivion.</p>

+<h2>CHAPTER XIX</h2>
+
+<p class="cap extraspacetop">THE startling and dramatic entrance of
+Richard Duvall into Mr. Stapleton's
+library, ending with his announcement of
+the whereabouts of the kidnapped child, and his
+subsequent collapse, threw the entire party into
+confusion.</p>
+
+<p>Mrs. Stapleton started up with a scream, her
+overwrought nerves no longer able to resist the
+frightful strain under which she had for so many
+days been laboring.</p>
+
+<p>Her husband, who had completely forgotten
+the detective's presence in the house, in his anxious
+vigil at the telephone, called out instantly to one
+of the servants, ordering him to tell Fran&ccedil;ois to
+bring his automobile to the door.</p>
+
+<p>Monsieur Lefevre, accompanied by Vernet,
+sprang quickly to Duvall's assistance. The Prefect
+felt that, if the latter's statement was correct,
+he had won out in the long duel for the honor
+of recovering the kidnapped child; but no consideration<span class='pagenum'><a name="Page_287" id="Page_287">[287]</a></span>
+of this nature could make him any less
+concerned for the detective's welfare, or any the
+less thankful that, no matter by whose efforts,
+the missing child had at last been located. He
+had hoped that to Grace Duvall would ultimately
+fall the prize of success; but these things were,
+after all, of no serious weight, compared with
+the great fact, that the success had at last come.</p>
+
+<p>Assisted by Vernet, he placed Duvall upon a
+couch, and called for brandy, and a basin of cold
+water.</p>
+
+<p>In a few moments, under Vernet's skilful ministrations,
+the detective's wound had been washed
+and temporarily bound up, and he had been restored
+to consciousness. A little of the brandy
+soon served to dispel his faintness. He declared
+himself ready to accompany the expedition to
+Passy.</p>
+
+<p>The Prefect endeavored to dissuade him; but
+to no purpose. The message which he had received
+in the chauffeur's room, to the effect that
+the person calling for help was Grace Duvall,
+his own wife, seemed so mysterious, so utterly inexplicable
+to him, that he could conceive no reasonable
+explanation for it. There was but one
+thing to do,&mdash;to go himself and sift the matter<span class='pagenum'><a name="Page_288" id="Page_288">[288]</a></span>
+to the bottom. He did not expect to find Grace
+there, and yet&mdash;what else could the message
+mean?</p>
+
+<p>Just as he staggered to his feet, with the announcement
+that he would accompany the party
+to Passy, two of the servants rushed into the
+library, and with scared faces announced that
+Fran&ccedil;ois lay, bound and unconscious, on the floor
+of his room. Mr. Stapleton looked quickly at
+Duvall.</p>
+
+<p>"It's all right, Mr. Stapleton," exclaimed the
+detective. "The fellow is one of the gang." He
+turned to Monsieur Lefevre. "You'd better have
+him placed under arrest at once. And if your car
+is here, we'll use that, instead of Mr. Stapleton's.
+There's not a moment to be lost."</p>
+
+<p>"By all means. My automobile is at the door.
+Vernet," he turned to his assistant, "have one of
+your men take charge of this fellow Fran&ccedil;ois
+at once. We must set out immediately."</p>
+
+<p>Mr. Stapleton took his wife in his arms, and
+embraced her tenderly. "Don't worry, dear," he
+said. "I'll be back with the boy, inside of half
+an hour. Come along!" he shouted to the others,
+as he made for the door. "No time to waste
+now."</p>
+
+<p><span class='pagenum'><a name="Page_289" id="Page_289">[289]</a></span>In a few moments the entire party, consisting
+of Mr. Stapleton, Duvall, Monsieur Lefevre, Vernet,
+and the Prefect's chauffeur, were driving toward
+Passy at a rate which set at naught all speed
+regulations and sent the few pedestrians who happened
+to cross their path scampering to the sidewalk
+for safety.</p>
+
+<p>Duvall explained, as they went along, the
+mysterious messages which he had received
+by flashlight. No one understood them but
+Monsieur Lefevre. He gave a great sigh of
+relief. The continued and unexplained absence
+of Grace had alarmed him greatly. Now he
+began to understand the reasons for it. That
+part of Duvall's story which spoke of haste, the
+appeal for prompt assistance, made him look
+grave. He leaned over to his chauffeur and urged
+him to even greater speed.</p>
+
+<p>The trees and houses along the Avenue Kleber,
+and later the Rue Franklin, swept by the speeding
+machine in a whirl of dust. In what seemed
+an incredibly short time the automobile dashed
+into the Rue Nicolo, and thundered up to No. 42.</p>
+
+<p>Vernet was the first to ascend the steps of the
+house, closely followed by Duvall and the others
+of the party. As they reached the front door,<span class='pagenum'><a name="Page_290" id="Page_290">[290]</a></span>
+and rapped loudly, they all heard a sudden commotion
+within, followed by cries and shouts and
+a fall. Instantly all four threw their combined
+weight against the door, shattering the lock and
+bursting it in.</p>
+
+<p>The semidarkness showed a terrifying spectacle.
+On the floor lay a woman, unconscious,
+clutching in her arms a child, trapped in a long
+gray coat. Down the dark hallway leading to
+the rear of the house dashed the figures of two
+men. One of them turned, as the attacking party
+entered, and hurled the lighted candle which he
+bore full into their faces. The entire scene was
+instantly plunged into darkness.</p>
+
+<p>The momentary light of the candle, however,
+had been sufficient to send a thrill of joy through
+at least one of the entering party. Mr. Stapleton
+recognized, in the white and tearful face of the
+child, his kidnapped boy, and, stooping, raised him
+tenderly in his arms.</p>
+
+<p>Duvall, not knowing whether the unconscious
+woman was the supposed agent of the police,
+Mademoiselle Goncourt, or Grace, his wife, lifted
+her in his arms and carried her out into the air.</p>
+
+<p>Vernet, followed by the Prefect, and the chauffeur,
+who had at once joined them, dashed fearlessly<span class='pagenum'><a name="Page_291" id="Page_291">[291]</a></span>
+along the dark passage by which the two
+men were attempting to escape.</p>
+
+<p>There was a crash, as the rear door was burst
+out, followed by a volley of shots as Vernet opened
+upon the fleeing men with his automatic revolver.</p>
+
+<p>In a moment the affair was over. The foremost
+of the two men crumpled up before he had taken
+half a dozen strides through the garden, and his
+companion raised his hands and surrendered, begging
+for mercy. Within a few moments he was
+handcuffed, and Vernet, bending over his wounded
+companion, was directing the chauffeur to summon
+an ambulance at once.</p>
+
+<p>Monsieur Lefevre returned hastily to the street.
+His sole concern now was for Grace. He prayed
+fervently that no serious harm had befallen her,
+and realized that Duvall was likely to resent bitterly
+the deception which has been practised upon
+him.</p>
+
+<p>The latter, however, was in no mood for recriminations.
+No sooner had he carried his unconscious
+burden to the street, when Grace opened
+her eyes, threw her arms about his neck, and
+kissed him.</p>
+
+<p>"Richard&mdash;Richard!" she cried, happily. "I'm<span class='pagenum'><a name="Page_292" id="Page_292">[292]</a></span>
+so glad&mdash;so glad!" then rested content in his
+arms.</p>
+
+<p>The detective's brain was in a whirl. In no
+possible way could he account for the presence
+here, in Paris, under such tragic and inexplicable
+circumstances, of the wife whom he had left, so
+short a time before, peacefully sitting on the rosecovered
+porch of their home in Maryland. The
+thing seemed incredible, unbelievable; yet here
+was Grace, with her soft arms about his neck, her
+kisses on his lips, to prove its reality.</p>
+
+<p>He looked at Monsieur Lefevre dully as the
+latter joined them upon the sidewalk, but could
+say nothing.</p>
+
+<p>"It seems," remarked the Prefect, with a grave
+smile, "that not only has Mr. Stapleton found his
+boy, but you have found your wife."</p>
+
+<p>Duvall frowned. "What is she doing here?"
+he asked.</p>
+
+<p>"We will speak of that later, my friend," observed
+Lefevre, quietly. "Just at present I propose
+that we return to Mr. Stapleton's without
+a moment's delay. Her heart is breaking with
+anxiety." He took Grace's arm and assisted her
+to enter the automobile, where Mr. Stapleton had
+already preceded them with his son. "It is to<span class='pagenum'><a name="Page_293" id="Page_293">[293]</a></span>
+you, my dear child," he said to Grace, as she sunk
+weakly back upon the cushioned seat, "that Mrs.
+Stapleton will owe all her happiness."</p>
+
+<p>It was a cheerful party that broke in upon the
+banker's wife a short time later. Duvall, under
+the stimulus of Grace's presence, had completely
+forgotten his wound; while Grace, who had been
+but momentarily stunned by the blow which the
+kidnapper had given her, was radiant with joy at
+once more feeling her husband's arms about
+her.</p>
+
+<p>Monsieur Lefevre carried them both off to his
+house, as soon as the boy had been restored to
+his mother. The happiness of the banker's reunited
+family was too great to permit them to be
+even mildly interested in the affairs of Richard
+Duvall and his wife, and they, too, wished to be
+alone. It seemed to them both as though ages
+had passed since they had seen each other; they
+could scarcely realize that it had been but a little
+over two weeks. Richard especially seemed
+unable to grasp the truth of the situation. He
+plied Grace with numberless questions, and could
+scarcely believe that he had actually been within
+arm's length of her on at least four different occasions
+during the past week without knowing it.</p>
+
+<p><span class='pagenum'><a name="Page_294" id="Page_294">[294]</a></span>Monsieur Lefevre advised him to leave the
+whole matter until the next day. "You should
+be proud of your wife, Monsieur," he said,
+gravely. "But for her, I doubt if Monsieur
+Stapleton would ever have seen his boy again.
+And that reminds me," he smiled mischievously,
+"that I have won that little bet. It was Mademoiselle
+Goncourt, of my office, that recovered
+the lost child."</p>
+
+<p>"I think the honors are pretty evenly divided,
+Monsieur," laughed Grace, happily, as she pressed
+her husband's hand. "Don't forget that if
+Richard hadn't gotten my message, all my work
+would have gone for nothing."</p>
+
+<p>"Suppose we call it a draw, then," said the Prefect.
+"All in the family, as you Americans say.
+And to show that I am not prejudiced, one way or
+the other, I suggest that you both, with Mr. and
+Mrs. Stapleton, dine with me tomorrow evening.
+There are many points connected with this case
+which are by no means cleared up, and we should
+talk them over. Although we have secured the
+missing child, and three of the kidnappers, we
+do not yet know how the child was stolen, or
+whether the nurse, Mary Lanahan, is innocent or<span class='pagenum'><a name="Page_295" id="Page_295">[295]</a></span>
+guilty of any part in his mysterious disappearance
+in the Bois de Boulogne. I confess that I have all
+along considered her guilty, and am inclined to
+order her arrest at once."</p>
+
+<p>"It will be useless, Monsieur," remarked Duvall,
+quietly. "She is entirely innocent."</p>
+
+<p>"You mean that she knows nothing of how the
+boy was spirited away?"</p>
+
+<p>"Nothing!"</p>
+
+<p>"Mon Dieu! Then the thing may forever remain
+a mystery."</p>
+
+<p>"Not at all. It is simple enough."</p>
+
+<p>Monsieur Lefevre turned to him with a look
+of inquiry. "You mean, then, that you have
+solved it?"</p>
+
+<p>"I do."</p>
+
+<p>"Then may I ask that you will be good enough
+to explain it at once?"</p>
+
+<p>Duvall laughed. "Monsieur Lefevre," he
+said, "I have a splitting headache, a bad wound
+in my cheek, and a burning desire to spend the
+next two hours talking to my wife." He drew
+Grace toward him, and put his arm through hers.
+"I am very much afraid that the explanation of<span class='pagenum'><a name="Page_296" id="Page_296">[296]</a></span>
+the disappearance of Mr. Stapleton's boy will
+have to be put off until tomorrow."</p>
+
+<p>Monsieur Lefevre watched the two as they
+went, arm in arm, up the stairs.</p>
+
+<p>"Mon Dieu!" he said softly to himself. "They
+are just as much in love with each other as
+ever."</p>
+
+<hr class="r15" />
+<p><span class='pagenum'><a name="Page_297" id="Page_297">[297]</a></span></p>
+<h2>CHAPTER XX</h2>
+
+<div class="cap">I MUST confess," remarked Monsieur Lefevre,
+as he sat with Mr. Stapleton and
+Duvall over their after dinner cigars the
+following evening, "that while the case as a whole
+appears simple enough to me, there are one or
+two points that I fail to understand."</div>
+
+<p>"There are a great many that <i>I</i> fail to understand,"
+exclaimed the banker, chewing reflectively
+on his cigar. "However, now that the boy
+is safe at home, it really makes very little difference."</p>
+
+<p>"On the contrary, Mr. Stapleton," remarked
+Duvall, "it makes a great deal of difference.
+For instance, I understand that you have discharged
+the nurse, Mary Lanahan."</p>
+
+<p>"Yes. You say that she is quite innocent of
+any part in the kidnapping of my boy; but the fact
+remains that I don't trust her. I am informed
+that she was married to that fellow, Valentin, this
+afternoon."</p>
+
+<p><span class='pagenum'><a name="Page_298" id="Page_298">[298]</a></span>Duvall smiled. "That was quite to be expected."</p>
+
+<p>"At one time," said Mr. Stapleton, "you believed
+this fellow Valentin to have been concerned
+in the plot."</p>
+
+<p>"Yes. That is true. My early investigations
+of the matter showed me at once that there was
+some understanding between these two, something
+which they were endeavoring to conceal.
+I did not at first understand the motive which
+actuated them. I thought it was guilt. In reality,
+it was love. Therefore I am not surprised to
+learn of their marriage." He gazed critically at
+his cigar for a time, in silence.</p>
+
+<p>"As matters have turned out, gentlemen," he
+resumed, after a few moments, "there is no cause
+for anything but congratulation on all hands.
+The child is recovered, the criminals are under
+arrest, the money&mdash;the hundred thousand dollars
+you paid out, Mr. Stapleton&mdash;was found
+on the kidnapper's person and returned to
+you."</p>
+
+<p>"Exactly. Nothing could be more satisfactory
+all around."</p>
+
+<p>"And yet," went on the detective, "I have never
+before taken part in a case in which I have done<span class='pagenum'><a name="Page_299" id="Page_299">[299]</a></span>
+so little, in which I have been so uniformly unsuccessful."</p>
+
+<p>Mr. Stapleton raised his hand. "My dear Duvall,"
+he began, "but for you, we should have
+been nowhere."</p>
+
+<p>"You are wrong, my friend. Had I kept out
+of the case altogether, your son would have been
+returned to you just the same. It is true that
+the men who kidnapped him would not have been
+caught, and your money would not have been
+returned to you; but the prime object which you
+sought, the recovery of your child, would have
+been realized in any event."</p>
+
+<p>"That is true," remarked the Prefect; "but,
+from the standpoint of the police, it is the detection
+and capture of the criminal that is desired,
+not the buying of him off. By insisting on that,
+Mr. Stapleton, you rendered our work extremely
+difficult."</p>
+
+<p>"So difficult, indeed," said Duvall, earnestly,
+"that but for the energy, the courage, the wit of
+a woman, all our plans would have failed. I
+refer to my wife. It is to her that all the credit
+in this affair is due."</p>
+
+<p>"By all means!" said Mr. Stapleton. "I could
+not fail to realize, when she told her story at<span class='pagenum'><a name="Page_300" id="Page_300">[300]</a></span>
+dinner tonight, how much Mrs. Stapleton and myself
+owe her. I shall have something to say on
+the subject of our debt, as soon as the ladies
+rejoin us. But tell us, Mr. Duvall, a little more
+about the case, as you now understand it.
+I confess that I am becoming more and more interested.
+What, for instance, was the mystery,
+if indeed there was any, connected with the box
+of gold-tipped cigarettes?"</p>
+
+<p>Duvall smiled. "That, my dear sir, is in
+fact the crux, the starting point, of the whole
+affair." He settled back in his chair comfortably.
+"Otherwise the case was simple enough. Certain
+scoundrels steal a child, hold it for ransom, and
+frighten the parents into paying over a large sum.
+Nothing unusual in that. A clever scheme or two
+for turning the money over, and returning the
+child&mdash;simple, yet perfect enough to defy all attempts
+to foil them.</p>
+
+<p>"The real mystery lay in the utter absence of
+any clues which would throw light on the actual
+stealing of the child. In this respect the case
+was unique. A trusted nurse swears that the
+child has disappeared in broad daylight, without
+the slightest knowledge of how it was accomplished.
+Here we have a case so simple, so<span class='pagenum'><a name="Page_301" id="Page_301">[301]</a></span>
+devoid of incident of any sort, that we are baffled
+at the very start by the impossibility of the thing.
+Yet the nurse is a woman of good reputation,
+honest, clearly telling what she believes to be the
+truth.</p>
+
+<p>"But a single clue existed upon which I could
+build the least semblance of a case. I refer to
+the half-smoked cigarette with the gold tip, which
+I discovered in the grass at the scene of the crime.
+Without that apparently trivial clue, the criminals
+would in all probability never have been captured
+at all."</p>
+
+<p>"But," exclaimed Mr. Stapleton, "I don't see
+how you make that out."</p>
+
+<p>"Nor I," observed the Prefect.</p>
+
+<p>"No. I suppose not. And yet, it is simple
+enough. That half-smoked cigarette and nothing
+else is the basic reason for the arrest of the three
+men now in your hands."</p>
+
+<p>Monsieur Lefevre smiled. "Be good enough,"
+he said, "to explain."</p>
+
+<p>"Very well, I will. But first, let me indicate
+to you my course of reasoning. When I originally
+found the cigarette, I regarded it as of very small
+value, from the standpoint of evidence. It happened
+to be lying in the grass at the point where<span class='pagenum'><a name="Page_302" id="Page_302">[302]</a></span>
+the crime occurred; but during the week or more
+which had elapsed between the stealing of the
+boy and my examination of the ground, a hundred
+people might have walked over the spot. I took
+it, because I realized that it <i>might</i> have a bearing
+on the case, and I have learned to discard no clue,
+however trifling it may appear, until it has been
+proven valueless.</p>
+
+<p>"Now to go back to the cigarette, I observed
+at once that it was of American make, yet of such
+small size as to have been either used by a woman,
+or by a man of rather effeminate taste.</p>
+
+<p>"Now if the cigarette had been used by a
+woman, it meant one of two things. Either it
+was used by Mary Lanahan herself, in which case
+it apparently proved nothing, or by some other
+woman who was there with her, and who might
+have had a hand in the kidnapping.</p>
+
+<p>"On the other hand, if used by a man, it pointed
+clearly to the chauffeur, Valentin, for several
+reasons. He was a friend, a former lover, of the
+nurse. He had been discharged by Mr. Stapleton
+for dishonesty. He was, I had reason to know,
+of rather a weak and effeminate type. The cigarette
+was of American make, and he had but recently
+come from America. These things pointed<span class='pagenum'><a name="Page_303" id="Page_303">[303]</a></span>
+to Valentin. The fact that the nurse was in love
+with him would cause her to shield him. I determined
+to try the matter out at once.</p>
+
+<p>"As soon as I returned to the house, therefore,
+I confronted her, and asked her if Valentin
+smoked gold-tipped cigarettes. I did this, not
+because I expected to get any reply of value, but
+because I wished to observe her manner, her face,
+when I flung the question at her.</p>
+
+<p>"She was greatly startled. She denied that
+Valentin smoked. Fifteen minutes later, she sent
+him a message to destroy the cigarettes.</p>
+
+<p>"I at once concluded that they were working
+together, and were both guilty, a conclusion in
+which, however much I was justified by the evidence,
+I was quite wrong.</p>
+
+<p>"Then came the attempt on the part of someone&mdash;the
+man with the black beard, I am told&mdash;to
+steal the cigarettes from Valentin. I learned
+that the man was followed to Mr. Stapleton's
+house.</p>
+
+<p>"This at once threw a new light upon the matter,
+although I will admit a confusing one. Someone
+else, besides the nurse, desired the box of
+cigarettes removed as evidence; someone, in fact,
+who belonged to, or had friends in, the house.<span class='pagenum'><a name="Page_304" id="Page_304">[304]</a></span>
+Who could this be? I could think of no one, outside
+of Mary Lanahan herself, but the chauffeur,
+Fran&ccedil;ois."</p>
+
+<p>"Why did you first suspect him?" asked Mr.
+Stapleton.</p>
+
+<p>"Because he was the only person, besides the
+nurse, who was present at the time of the kidnapping.
+I did not abandon my suspicions of
+either the nurse or Valentin. I fully believed
+that they knew a great deal more about the affair
+than they admitted. But I became convinced that
+Fran&ccedil;ois, too, was in the thing. He had testified
+that he was asleep when the affair occurred. I
+concluded at once that he was lying.</p>
+
+<p>"At the first opportunity, therefore, I made a
+thorough search of his room, and found the box
+of cigarettes hidden in a clock on his mantel."</p>
+
+<p>"Ha! I did not know that," exclaimed the
+Prefect. "What were they doing there?"</p>
+
+<p>"I concluded that the fellow with the black
+beard who stole them from Valentin, in order to
+prevent their use as evidence against him, turned
+them over to Fran&ccedil;ois for a definite purpose."</p>
+
+<p>"And that purpose was?"</p>
+
+<p>"Their use in subsequent crimes of a similar
+nature."</p>
+
+<p><span class='pagenum'><a name="Page_305" id="Page_305">[305]</a></span>Mr. Stapleton and the Prefect gazed at Duvall
+in bewilderment. "Explain yourself, my friend,"
+exclaimed the latter. "I confess I do not understand
+what you are talking about. Who, may I
+ask, really smoked the cigarette, the remains of
+which you found in the grass?"</p>
+
+<p>"Mary Lanahan," said the detective, with a
+smile.</p>
+
+<p>"The nurse! Name of a dog! Then I fail
+to see that the matter is of the slightest importance
+one way or the other."</p>
+
+<p>"On the contrary, Monsieur, it is of the greatest
+importance. May I ask whether you are, by
+any chance, familiar with the properties of an
+Eastern drug, made from hemp, and generally
+known as hashish?"</p>
+
+<p>The Prefect sat up suddenly, and clapped his
+hands to his knees. "Mon Dieu!" he exclaimed.
+"Now I begin to understand."</p>
+
+<p>"More than I do," said Mr. Stapleton.</p>
+
+<p>"The cigarettes were drugged, that is all,"
+went on Duvall. "The men who planned this
+thing went to work very carefully. They ascertained,
+through Fran&ccedil;ois, that Mary Lanahan was
+in the habit, no doubt on the sly, of using cigarettes.
+I discovered the fact, myself, before I<span class='pagenum'><a name="Page_306" id="Page_306">[306]</a></span>
+left New York. They also learned that she
+smoked the same brand as Mrs. Stapleton herself
+used. No doubt she helped herself from Mrs.
+Stapleton's supply. They therefore secured, also
+through Fran&ccedil;ois, a box of these cigarettes, and
+had them heavily drugged with hashish. The box
+of drugged cigarettes was substituted, later on,
+for her own."</p>
+
+<p>"But," exclaimed Mr. Stapleton, "how could
+Mary Lanahan swear that she turned away but
+a moment&mdash;that no one came near her?"</p>
+
+<p>"When Mary Lanahan testified that, she believed
+that she was telling the truth. The hashish
+had simply destroyed her conception of the passage
+of time."</p>
+
+<p>"Is that its effect?"</p>
+
+<p>"Yes. It produces a delightful languor, a
+stupor in which all realization of the passage of
+time ceases. Sometimes, to those who use the
+drug, it may apparently require hours to walk
+a few yards. To make a momentary movement
+of the hand may seem to take many minutes. On
+the other hand, in the stupor which the drug
+induces, hours may be spent in the contemplation
+of a flower, a bit of scenery, the page of a
+book, without any realization on the part of the<span class='pagenum'><a name="Page_307" id="Page_307">[307]</a></span>
+user that more than a few seconds have elapsed.
+That is what happened to Mary Lanahan. She
+inhaled a few puffs of the cigarette, heavily
+charged with the drug; without knowing, of
+course, of its presence. She probably passed at
+once into a state of stupor which may have extended
+over fifteen minutes or more. She was not
+unconscious. She sat upon the grass, looking
+off toward the distant sky, in a waking dream,
+not unlike a trance, in which all the world about
+her&mdash;the world of sound, of movement&mdash;had
+simply ceased to exist. She was to all intents and
+purposes unconscious of what was going on about
+her. The kidnapper, whom I strongly suspect
+to be Fran&ccedil;ois, merely strolled up behind her,
+picked up the boy, and walked off with him."</p>
+
+<p>The detective's listeners looked at him in astonishment.
+Presently Mr. Stapleton spoke.
+"Why do you think it was Fran&ccedil;ois?" he asked.</p>
+
+<p>"Oh, for many reasons. Had he, on approaching,
+found the nurse not sufficiently under
+the influence of the drug, he could have pretended
+to wish to speak to her, on some trivial matter.
+Again, the child would go away with him of
+course without making an outcry, which he would
+probably not have done, with a stranger. There<span class='pagenum'><a name="Page_308" id="Page_308">[308]</a></span>
+are other reasons. He no doubt took the boy
+to the road, and handed him to his confederates,
+passing in another car. The affair occurred, you
+will remember, in a little frequented part of the
+Bois.</p>
+
+<p>"The subsequent actions of Mary Lanahan
+are a trifle difficult to account for; but I suppose
+them to have been as follows: On slowly coming
+out of her stupor, and realizing that the boy
+was gone, she was terribly frightened. It had
+seemed to her but a moment since she turned
+away. She fears that the cigarette has made her
+drowsy&mdash;she has heard that they sometimes contain
+opium. She thinks she may have dozed off;
+but is not willing to admit it. Especially does
+she not want her employers to know that she uses
+cigarettes. She fears that such knowledge would
+cost her her place. It is not until later that she
+begins to suspect the cigarettes."</p>
+
+<p>"When is that?" inquired Lefevre.</p>
+
+<p>"Several days later, when she is supposed to
+have been poisoned. She was with Valentin at
+the time; although, on account of Mr. Stapleton's
+dislike for him, she feared to admit it. She
+smokes another of the cigarettes, while sitting on
+a bench with him, in the Champs &Eacute;lys&eacute;es. Suddenly<span class='pagenum'><a name="Page_309" id="Page_309">[309]</a></span>
+she is taken ill&mdash;a frequent result of hashish,
+when taken in excessive doses, or by one
+otherwise nervously upset. Valentin takes the
+box, puts her into a cab, and goes to his room,
+where he leaves the cigarettes. No doubt, as she
+begins to feel ill, she discusses with him the possibility
+of the cigarettes having been poisoned. It
+is for that reason that she gives them to him.</p>
+
+<p>"Her sudden message to Valentin to destroy
+them arose from a fear that I would discover
+the part which they had played in the boy's loss.
+This would, she knew, not only cost her her place,
+but would make her, in a way, responsible for the
+entire affair. She feared Mr. Stapleton's wrath,
+and therefore both she and Valentin remained
+dumb, so far as the cigarettes were concerned.</p>
+
+<p>"They both, however, were all this time doing
+their best to find the child. Her message to Valentin,
+that she was suspicious of Fran&ccedil;ois, telling
+Valentin to watch him, arose no doubt from a
+realization that the box of drugged cigarettes
+had been substituted for her own by the chauffeur.</p>
+
+<p>"Valentin, acting on her advice, does watch
+Fran&ccedil;ois, as his presence clinging to the rear of
+the latter's car the other night has proved. He<span class='pagenum'><a name="Page_310" id="Page_310">[310]</a></span>
+tells me, today, that Fran&ccedil;ois did not take his
+car to the garage that night at all. The men
+there who so testified lied, at his request, supposing
+it merely an excuse to cover a joy ride.</p>
+
+<p>"Fran&ccedil;ois, not wishing that the drugged cigarettes
+should remain in the nurse's hands as evidence
+against him, evidently made an attempt to
+recover them, discovered that she had turned
+them over to Valentin, and, being watched himself,
+sent word of the matter to his confederate,
+the fellow who went about in the black beard. He
+must have been admitted to Mr. Stapleton's house
+that night by Fran&ccedil;ois himself.</p>
+
+<p>"I came to the conclusion, early in the course
+of my investigations, that the cigarette, the end
+of which I had found in the Bois, had been
+smoked by Mary Lanahan, and I so told Mr.
+Stapleton."</p>
+
+<p>The banker nodded. "Yes," he said; "but
+you did not then say anything about the hashish."</p>
+
+<p>"I was not certain of it. I intended to have
+the fragment I had found analyzed. When I
+discovered the cigarettes in Fran&ccedil;ois' room, you
+will remember that I took one of them. I smoked
+that cigarette, before going to bed that night.
+It produced exactly the sensations that Mary Lanahan<span class='pagenum'><a name="Page_311" id="Page_311">[311]</a></span>
+must have felt. I floated away in the land
+of dreams for over half an hour, and came to
+with no recollection whatever of the passage of
+time. It is a remarkable drug, but an extremely
+dangerous one.</p>
+
+<p>"After that, the case became simple enough. I
+knew at once, beyond any question, that Fran&ccedil;ois
+was one of the kidnappers. My plans last night
+would have worked perfectly, but for the chauffeur's
+accidental discovery of me, hiding in the
+closet. Had that not happened, the boy would
+have been returned, according to program, and
+Fran&ccedil;ois I had safely in my hands."</p>
+
+<p>"But we wouldn't have got the others," laughed
+the Prefect. "You must thank your wife for that.
+Vernet has told me how the kidnappers outwitted
+you at the Avenue Malakoff. The car from which
+the signal apparently was made contained a well
+known stockbroker, who knew nothing of the
+matter at all. He merely happened to be passing
+the Avenue Malakoff at the precise moment when
+the signal was given to Fran&ccedil;ois."</p>
+
+<p>"You are mistaken, Monsieur," observed the
+detective, quietly. "The signal was undoubtedly
+made from that car; not by Monsieur Lemaitre,
+I will admit, but by his chauffeur. He has admitted<span class='pagenum'><a name="Page_312" id="Page_312">[312]</a></span>
+to Vernet that a stranger paid him fifty
+francs to do so, on the plea that it was some signal
+to a woman. The man knows nothing of the
+affair, beyond that."</p>
+
+<p>As he finished speaking, there was a ripple of
+laughter from the hall, and Mrs. Stapleton,
+Madame Lefevre, and Grace came in.</p>
+
+<p>"We have been debating a most important question,"
+said Mrs. Stapleton, with an assumption of
+extreme gravity, "and we beg that you, Monsieur
+Lefevre, will be so good as to decide it."</p>
+
+<p>"What is this question so grave, Madame," inquired
+the Prefect, rising, with a smile. "I am all
+impatience to hear it."</p>
+
+<p>"The question is this, Monsieur Lefevre:
+Which deserves the greater credit for the recovery
+of my boy&mdash;Mr. Duvall, or his charming
+wife?"</p>
+
+<p>The Prefect stepped forward, placed one hand
+affectionately upon Duvall's shoulder, and with
+the other grasped Grace by the arm.</p>
+
+<p>"The question you propound, Madame," he
+said, looking from the detective to his wife with
+a smile, "is easily answered. The credit belongs
+equally to both. And that, my children, is as it
+should be. This affair, so happily terminated,<span class='pagenum'><a name="Page_313" id="Page_313">[313]</a></span>
+has taught me one important lesson. It is this:
+The husband and the wife should never be in
+opposition to each other. They must work
+together always, not only in matters of this
+sort, but in all the affairs of life. I attempted a
+risky experiment in allowing these two dear
+friends of mine to attack this case from opposite
+sides. But for some very excellent strokes of
+luck, it might have resulted most unhappily for all
+concerned. Hereafter, should Monsieur Duvall
+and his wife serve me, it must be together, or not
+at all." He turned to Grace. "I feel that I
+owe you both a great debt, my child, for having
+once again so rudely interrupted the course of
+your honeymoon. What reparation can I make?
+Ask of me what you will."</p>
+
+<p>"Anything?" inquired Grace, laughing.</p>
+
+<p>"Anything." The Prefect bowed gallantly.</p>
+
+<p>"Then I demand your promise, Monsieur, to
+visit us at our place in Maryland, before the end
+of the year."</p>
+
+<p class="extraspacebot">"That," exclaimed the Prefect, as he bent and
+kissed her hand, "would be the most delightful
+way of paying a debt that I could possibly
+imagine."</p>

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

+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal

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

+
+
+
+CHAPTER I
+
+
+The big, mud-spattered touring car, which for the past hour had been
+plowing its way steadily northward from the city of Washington,
+hesitated for a moment before the gateway which marked the end of the
+well kept drive, then swept on to the house.
+
+A man, stoutly built, keen of eye, showing haste in his every movement,
+sprang from the machine and ascended the veranda steps.
+
+"Does Richard Duvall live here?" he inquired, curtly, of the smiling old
+colored woman who came to the door.
+
+"'Deed he do, suh. Does you want to see him?"
+
+"Yes. At once, please. Tell him it is most important. My name is
+Hodgman."
+
+The servant eyed him with cool disfavor. "Set down, suh," she remarked
+stiffly. "I'll tell him you is here."
+
+The caller watched her, as she disappeared into the house, then cast
+himself impatiently into a chair and lit a cigar.
+
+He paid no attention to the attempts of two clumsy collie puppies to
+attract his favorable notice, but contented himself with making a quick
+survey of the wide comfortable veranda, with its big roomy chairs, the
+wicker table, bearing a great jar of red peonies, the smooth green
+lawns, swept by the late afternoon sun.
+
+"Fine old place," he muttered to himself. "Wonder if I can persuade him
+to go?"
+
+As the car which had brought Mr. Hodgman on his hasty trip from
+Washington dashed up to the front of the house, Grace Duvall, looking
+very charming in a blue linen dress, was just approaching it from the
+rear.
+
+She held a pair of shears in her hand, and her apron was filled to
+overflowing with hundred-leaf roses. "Dick--oh, Dick!" she called, as
+she came down the long avenue of syringas and lilacs which led to the
+house. "The sweet peas are nearly ready to bloom."
+
+Richard Duvall, looking as simply pastoral as though he had never
+tracked an international crook to cover, raised his head from the
+flower bed, in which he had been carefully setting out circle after
+circle of geranium plants.
+
+"Are they?" he laughed. "That's good. Now all we need is a few good hot
+days." He gathered up his trowel and rake, and started toward the barn.
+
+Grace put her arm through her husband's and together they strolled
+across the springy green turf, their faces smiling and happy. The
+honeymoon showed no signs of waning.
+
+This lovely old country place, in southern Maryland, had been one of
+Richard Duvall's dreams for many years, and after his marriage to Grace
+Ellicott, in Paris, it had become hers, as well. It was but a short time
+after their return to America that they decided to make it a reality.
+
+Grace had encouraged her husband in the plan of giving up, for a time at
+least, his warfare against crime, his pursuit of criminals of the higher
+and more dangerous type, and had persuaded him to buy the farm which had
+once belonged to his mother's people, and settle down to the life of a
+country gentleman.
+
+His office was still maintained, under the able direction of one of his
+assistants, but Duvall gave little or no attention to its affairs. He
+was glad to withdraw, for the first time in over nine years, from
+active work, and devote his energies to early potatoes, prize dogs,
+hunters, and geranium plants--and, above all, to the peaceful enjoyment
+of his honeymoon, and the making of Grace the happiest woman in the
+world.
+
+She, on her part, found in their present situation all the joys of
+existence for which she had longed. With little or no liking for the
+monotonous round of society and its duties, and a passionate love of
+nature, she found in the many and complex duties of managing her part of
+their extensive estate a far greater happiness than any which city life
+could have offered her.
+
+The considerable fortune which her husband's clever work while in Paris
+had restored to her, had been safely invested in well paying securities,
+and she found her greatest joy in utilizing at least a part of her
+income in beautifying their new home.
+
+Richard had steadily refused to make any use of the money. It was a
+matter of pride with him, that his own savings had enabled him to
+purchase the property; but when Grace proposed to build an addition to
+the house, to provide him with a more comfortable library and work room,
+or insisted upon having the roads throughout the place elaborately
+macadamized, he was obliged to submit to her wishes. In this way, they
+planned and built for the future, together.
+
+The farm was a large one, comprising some two hundred acres, and the old
+stone house surrounded by white oaks and tulip poplars had once been a
+show place, before the declining fortunes of its former owners had
+caused it to fall into a state of mellow and time-honored decay. Now all
+was changed. Grace, with the able assistance of old Uncle Abe Turner, a
+relic of ante bellum times, spent hours daily in bringing order out of
+the chaos of tangled myrtle and ivy, overgrown box and hedge, thickets
+of syringa and lilac bushes and weed-grown lawns.
+
+It was a gigantic task, yet a joyous one--as it ever is, to those who
+came to it with the love of nature in their hearts. To Grace, the plants
+and shrubs, the great strong oaks, the towering poplars, each seemed to
+have a distinct personality. Under her energetic hand, the place once
+more took on the aspect of well kept and orderly beauty which was such a
+contrast to its former down-at-the-heels appearance. It seemed as though
+the growing things realized the personal interest she took in them, and
+responded as they never respond to the ignorant or unsympathetic.
+
+Richard was concerned with his fields of timothy and clover, his early
+corn, his berries and fruit trees, to say nothing of his collies, his
+prize cows and Kentucky horses. In such a life, time never hangs
+heavy--he was busy studying, planning, working, from morning to night,
+and his active mind soon convinced his capable overseer and the farm
+hands as well that, although Richard Duvall was by no means a
+professional farmer, he could still show them a thing or two when it
+came to the rotation of crops, the spraying of fruit trees, or the
+proper treatment of worn out soils. These were aspects of farming life
+which the hide-bound conservatism of the local farmers caused them to
+jeer at, as newfangled notions gotten from books. Later when they saw
+the man who farmed with his head as well as his hands gather in two
+bushels where they had barely been able to secure one, they began to sit
+up and take notice.
+
+"I got the new hedges all set out today," Grace went on, as she patted
+her husband's rather grimy hand. "They will be charming, against the
+gray stone of the wall. But we must have new gate posts. The old ones
+are likely to tumble into the road at any moment."
+
+"I'll have Martin come out tomorrow and look them over. There's plenty
+of stone--down in the lower pasture. Why not carry the wall right along
+the whole front of the property? It ought not to cost a great deal."
+
+"We will. And I'm going to have a new spring house built, too. The old
+one is falling to pieces." She looked up at her husband as he deposited
+the rake in the tool room and they started up the shaded walk toward the
+house. "Aren't you glad, Dick, that we're _alive_?"
+
+He pressed her arm. "Well--I should say so, little girl! Why do you ask
+me that?"
+
+"Oh--you know what your friends all said--that a man might as well be
+dead, as buried out here in the country. I think they are the ones who
+are not alive--cooped up in the city. Don't you?"
+
+Richard nodded. He was thinking for the moment of his former active
+life--when some battle of wits with a noted crook had kept him sleepless
+for nights. "It's--rather different," he laughed. "Isn't it?"
+
+"Yes--and much better. Don't you think so, dear? You wouldn't want to go
+back to it--would you?"
+
+"Not for anything in the world," he assured her, as he swept the newly
+seeded lawns with a contented glance. "I liked the other life, of
+course--the excitement, the danger of it; but this is better--much
+better. Here, Don!" he called to a graceful collie which was barking
+vociferously at some distant vehicle in the road. "Come here and be
+quiet." He turned with Grace to the great vine-covered side porch and
+sank contentedly into a rocking chair. "Well, little girl--it's been a
+busy day, and I'm tired. We got the early rye all cut on the lower field
+today. Guess we'll put in late potatoes, after it's plowed. Here,
+Don--come back here! What's the matter with you?" He rose and whistled
+to the dog, which was bounding across the lawn in the direction of the
+road. "Come back, I say!"
+
+"It's someone coming in," said Grace, uneasily. "In a machine. I wonder
+who it can be?"
+
+"Possibly Hudson, the veterinary. He was coming today, to look at that
+heifer."
+
+"He hasn't a machine like that. This is a big touring car." She turned
+to her husband. "Hadn't you better go in and fix up a bit, Dick? It may
+be company."
+
+Duvall laughed. "If it is, they'll have to take me as I am," he said;
+then again called to the dog.
+
+A moment later the servant, who had interviewed the caller at the front
+door, came out to the side porch. "Gentleman to see you, Mr. Duvall,"
+she said. "Seems to be in a powerful hurry, too."
+
+"All right, Aunt Lucy," said Duvall as he made his way to the front of
+the house.
+
+"Is this Richard Duvall?" the visitor asked, in a quick, almost
+peremptory tone, as the detective joined him.
+
+"Yes. That is my name. What can I do for you?"
+
+The newcomer rose nervously from his chair and began chewing upon his
+half-smoked cigar. "Had the devil of a time to find you, Mr. Duvall."
+
+"You came out from Washington, I suppose," remarked the detective,
+wondering what his visitor could want with him.
+
+"Yes. Got your address from Hicks, of the Treasury Department. He said
+you were about twelve miles out. I seem to have come about twenty."
+
+"Perhaps you went around by way of Laurel. It's much further, that way.
+What can I do for you, Mr.----" He paused interrogatively.
+
+The man looked up at him quickly. "My name's Hodgman--Thomas Hodgman--of
+New York. I represent John Stapleton."
+
+"John Stapleton, the banker?" asked Duvall, surprised.
+
+"Yes. You know him, don't you?"
+
+"Yes. Quite well. I handled a case for him once--some years ago. Why?"
+Duvall's face became grave. He began to realize that the interview was
+likely to become suddenly important. John Stapleton, the
+multi-millionaire banker, was not in the habit of sending messengers to
+anyone, without good reason.
+
+"So he said," went on Mr. Hodgman, resuming his chair. "That's why I'm
+here. He wants you to take another--"
+
+"Another?"
+
+"Yes. Another case. Quick."
+
+"It's quite out of the question."
+
+"Nonsense! This is important. Money's no object; name your own terms."
+
+"It isn't a question of terms, Mr. Hodgman. I have withdrawn, for the
+time being at least, from active professional work."
+
+"I know." The visitor flicked the ashes impatiently from his cigar and
+sought nervously in his pockets for a match. "That's what they told me
+at your office, in New York. Said you were on your honeymoon, and didn't
+want to be bothered."
+
+"That's true. I don't."
+
+"I told Mr. Stapleton that. He sent me to see you; said you might change
+your mind, when you heard about the case."
+
+"It is quite impossible. I do not care to take up any detective work at
+present."
+
+Mr. Hodgman fidgeted nervously in his chair. "You must listen to what I
+have to say, Mr. Duvall, at any rate. Mr. Stapleton would not hear to my
+returning, after seeing you, without having explained to you the nature
+of the case."
+
+Duvall leaned back, and began to fondle the long moist nose of the
+collie which sat beside his chair. "If you insist, Mr. Hodgman, I will
+listen, of course; but I assure you it will be quite useless."
+
+"I hope not. The case is most distressing. Mr. Stapleton's only child
+has been kidnapped!"
+
+"Kidnapped!" Duvall sat up with a start, every line of his face tense
+with professional interest. "When? Where?"
+
+"In Paris. The cablegram arrived this morning. I don't know the details.
+Mrs. Stapleton has been spending the winter abroad. Mr. Stapleton was to
+join her this month. She is living at their house in the Avenue Kleber,
+Paris. The child was out walking with a nurse. It has been stolen.
+That's all I know."
+
+"When did it happen?"
+
+"Yesterday morning. Mrs. Stapleton did not cable at first, believing
+that the boy would be found during the course of the day. Naturally she
+did not wish to alarm her husband needlessly, and the Prefect of Police,
+it seems, had assured her that the child would undoubtedly be recovered
+before night. It wasn't. This morning Mr. Stapleton got a long cablegram
+from his wife, telling him of the boy's disappearance. He's half crazy
+over the thing."
+
+"What is he going to do?"
+
+"I don't know. He sent me to see you at once. I'm his secretary, you
+know. When I couldn't find you in New York, he told me to come here. I
+arrived in Washington an hour ago, and came right out. Mr. Stapleton
+said if any man on earth could find his boy for him, you could."
+
+"I suppose the thing is a matter of blackmail--ransom--"
+
+"Very likely. They will probably demand a huge sum. No requests have
+been made, as yet, so far as I know. These fellows usually wait a week
+or two, before showing their hand, to give the unfortunate parents a
+chance to worry themselves half to death. I suppose they figure that
+then they'll be more likely to come across with the money."
+
+"Yes. That's the scheme. A rotten business, too. Hanging is too good for
+such wretches!"
+
+"That's what I say. Of course you can understand how Mr. Stapleton
+feels."
+
+"Of course. He will sail at once, I suppose."
+
+"That's the worst of it. He can't go till Saturday. Tomorrow's
+Thursday--that's three days off. There's a deal on here involving
+millions--something he's been working to put through for months. Of
+course he doesn't consider anything like that, when it comes to his
+child; but he's got to think of his associates--men who have intrusted
+their money to him. He can't possibly sail before Saturday. He wants you
+to go ahead of him. There's a fast boat leaving in the morning. You
+could take that. We can have a conference tonight. It will mean mighty
+quick work, though." He glanced at his watch. "After six now. There's no
+train till midnight--the sleeper. But Mr. Stapleton told me to charter a
+special. We can be in New York by one o'clock in the morning, if we
+start right now." He looked at Duvall in eager expectancy.
+
+The latter frowned, his gaze wandering off to the distant fields, where
+the newly plowed earth reminded him of his plans for the morrow. Yet
+here was a man, a friend, who had helped him much, in the earlier days
+of his career, begging him to come to his assistance in a matter almost
+of life or death. It was a difficult decision that he was called upon to
+make. The thought of leaving Grace hurt him deeply; yet she would prefer
+to stay behind, in case he should go, to look after the affairs of the
+place. With the assistance of the overseer and the hands, he knew that
+she could manage everything during a brief absence on his part--it
+seemed unlikely that the matter would require more than three or four
+weeks, at the outside.
+
+Mr. Hodgman broke in upon his thoughts. "You'll go, Mr. Duvall? Mr.
+Stapleton is depending on you. He has the utmost faith in your
+abilities. He knows your familiarity with Paris--the work you have done
+there, in the past. He believes that, by intrusting the matter to a
+fellow countryman, he will get his boy back again. He hasn't much faith
+in foreign detectives. He's set his heart on having you start for Paris
+at once. I can't go back and tell him that you have refused." Mr.
+Hodgman spoke in a loud and earnest voice, due to his very evident
+excitement. Neither he nor Duvall noticed that Grace had approached
+them, and was standing in the open doorway of the house.
+
+Before the detective had an opportunity to reply, Grace spoke. "What is
+it, Richard?" she inquired, quietly.
+
+Duvall rose, presented Mr. Hodgman to his wife, and bade her sit down.
+Then, in a few words, he acquainted her with the circumstances which led
+to the latter's visit.
+
+"Think of that poor mother, alone there in Paris," Hodgman supplemented.
+"Think of her suffering, her anxiety. I realize how much we are asking,
+to take Mr. Duvall away from you, especially at this time; but, it is
+Mr. Stapleton's only child--a boy of six. You can understand how he must
+feel."
+
+Grace nodded. "Yes, I can understand," she said, slowly, then turned to
+her husband.
+
+"What do you think, dear?" he asked her.
+
+"I think, Richard, that you had better go."
+
+Mr. Hodgman sprang to his feet, and, coming over to Grace, took her
+hand. He knew that his battle was won. "I thank you, Mrs. Duvall," he
+said, "on Mr. Stapleton's account, as well as on my own. He will
+appreciate deeply what you have done, the sacrifice you are making, and
+he will not forget it." He looked again at his watch nervously, the
+anxiety he felt clearly evident in his every movement. "We had best
+start at once, Mr. Duvall."
+
+Duvall rose. "I will join you in a short while, Mr. Hodgman. I wish to
+say a few words to my wife." He took Grace's arm and drew her within the
+house, leaving Mr. Hodgman pacing nervously up and down the veranda.
+
+The conference between Grace and her husband was short. Each realized
+the distress which tore at the other's heart, as well as the dangers he
+would in all probability be called upon to face; yet they met the
+situation calmly. "You will not be gone long," she told him. "I can
+manage very well."
+
+"I know you can, dear," he said, pressing her to him. "I'm not worried
+about the place. You can run that as well as I can. It's you, I'm
+worried about--leaving you"--
+
+"I'll be all right," she assured him, in spite of her tears. "I have
+Aunt Lucy, and old Uncle Abe, and Rose, and Jennie. I won't be so _very_
+lonely. And you will be very careful--and--and come back soon--won't
+you?"
+
+"Of course, dear. Very soon. Now I'd better get a few things together."
+
+Fifteen minutes later Grace Duvall stood on the steps of the veranda,
+watching the flying automobile as it rapidly became a little red blur in
+the distant road. It was nearly dark. The frogs in the patch of marsh in
+the meadow were piping dismally. She shivered, and a great sense of
+desolation came over her. She sank into a chair and wept, while Don,
+inserting his long white muzzle between her hands, strove to lick away
+her tears.
+
+She heard Aunt Lucy, the old negro cook, singing away at her work in the
+kitchen, accompanied by Uncle Abe, who occupied a bench on the back
+porch. Everything seemed strangely peaceful, and lonely, too, now that
+Richard had gone. She patted the eager head of the collie. "We'll have
+to make the best of it, Don," she said, and rose to enter the house.
+
+Suddenly far down the road she heard the chugging of an automobile. They
+were not frequent visitors, upon this country road. Could it be Richard,
+she wondered, returning for something he had forgotten?
+
+She stood, straining her eyes into the dusk, waiting, while with one
+hand she restrained the eager dog.
+
+Presently she saw that the machine was not a red one. It was not
+Richard. She was about to enter the house, when she realized that the
+rapidly moving car had entered the grounds. She turned on the lights in
+the hallway and stood, waiting, the dog at her side bristling with
+anger.
+
+In a moment the automobile had stopped, and almost before she realized
+it, a small, foreign-looking man stood on the doorstep before her.
+"Madame Duvall?" he inquired, quickly, in a voice which showed plainly
+his nationality.
+
+"Yes," she replied.
+
+"Your husband! May I see him?"
+
+"He is not at home."
+
+The newcomer seemed greatly disturbed. "Then I fear, Madame, that I
+shall be obliged to wait until he returns."
+
+"He will not return. He has gone away for sometime."
+
+"Ah! That is indeed a calamity!" The man's face showed the keenest
+disappointment. "May I ask where I can find him?"
+
+"It will be quite impossible." Grace had no intention of telling her
+visitor where her husband had gone. She knew too well the intricacies of
+his profession, for that. "You cannot find him." She made as though to
+close the door, and thereby terminate the interview.
+
+The newcomer realized her intention. Slowly he raised his hand, in the
+palm of which showed the seal of a ring, turned inward. It was of
+silver, with curious figures worked into it in gold. The man glanced
+from the ring to Grace, eying her steadily. "I think, Madame," he said,
+with a meaning smile, "that you can trust me."
+
+Grace recognized the ring at once. It was similar to one she herself had
+worn, while engaged in the memorable search for the ivory snuff box for
+Monsieur Lefevre, Prefect of Police of Paris. Dear old Lefevre--the
+friend of Richard's, and of her own! This man who stood before her must
+be a messenger from him.
+
+"Come in, please," she said, quietly, and led the way to the library.
+
+The man followed her, calling out a few words to his chauffeur as he did
+so. No sooner had they reached the great book-lined room, than he drew
+from his pocket a sealed envelope.
+
+"Madame Duvall," he said, earnestly, "Monsieur Lefevre has cabled to his
+representatives in Washington a message. That message is contained in
+this envelope. I have instructions to deliver it to your husband
+immediately. In case I could not find him, I am to hand it to you.
+Permit, me, Madame." With a bow, he placed the message in her hand.
+
+Grace took the envelope, broke the heavy seal which it bore, and drawing
+out a slip of paper, hastily read the contents. The message was from
+Monsieur Lefevre. It said:
+
+ My dear Duvall:
+
+ You promised, on the occasion of our last meeting, to come to me
+ should I ever need you. I need you badly, my friend. Come at once,
+ both you, and your dear wife. LEFEVRE.
+
+Grace looked up at the man before her, the letter crumpled in her hand.
+Here was a message the urgency of which could not be denied. She knew
+that, had Richard been at home, he would have gone to Paris at once in
+response to it; for it was to Monsieur Lefevre that they in reality owed
+all their happiness. She recalled vividly their wedding, with the
+lovable old Frenchman, acting as her father for the occasion, giving
+away the bride. She remembered the farewell dinner at the Prefect's
+house, and the beautiful gift he had given her on that occasion.
+Evidently Monsieur Lefevre desired Richard's presence very greatly, and
+her own as well. The thought suddenly came to her--why not go to him?
+
+True, Richard had left her in charge of things at home; but she knew
+that, for a reasonable time, at least, they would go on smoothly enough
+without her. Hendricks, the overseer, was a capable and honest man,
+devoted to her and to her husband.
+
+She could safely leave matters in his charge. Then, too, the thought of
+surprising Richard on the steamer sailing the next day appealed to her
+sense of mischief. How astounded he would be, to find her strolling
+along the deck! And how delighted, too! She wondered that the thought of
+accompanying him had not occurred to her more strongly before. She
+turned to the man, who stood watching her narrowly.
+
+"You know the contents of this message?"
+
+"Yes, Madame," he bowed. "It came to us by cable--in cipher."
+
+"There is a train for New York at midnight, and a steamer tomorrow
+morning."
+
+"Yes, Madame."
+
+"Can you drive me to Washington in your car?"
+
+"I shall be delighted, Madame." The fellow's eyes sparkled with
+satisfaction.
+
+"Very well. Mr. Duvall is in New York. I will take the message to him.
+Wait here, please, until I get some clothes together and give some
+orders to my servants."
+
+In half an hour, the thing was done. Hendricks, the overseer, had been
+given full instructions regarding taking charge of the place, with
+provision for his needs in the way of money, etc., and by ten o'clock,
+at which time the New York sleeper was open, Grace was at the station,
+purchasing her ticket.
+
+The obliging Frenchman gave her every assistance, and bade her _bon
+voyage_ smilingly as he helped her aboard the train. She retired at
+once, and lay in her berth, reading a magazine, and picturing to herself
+Richard's mingled astonishment and joy at their meeting in the morning.
+This time, she was determined that their honeymoon should not be
+interrupted.
+
+After a time, she fell asleep, and dreamed that she and Richard were
+sailing gaily toward Paris, in a large red touring car.
+
+In the morning, she ate a hasty breakfast in the railway station, and
+took a taxicab for the steamship offices. By great good fortune, she was
+able to secure a cabin. Then she hastily visited a banking house where
+she was well known, provided herself with funds, and drove to the dock.
+
+It wanted but half an hour till sailing time. Grace hastened to her
+stateroom, and busied herself in effacing the stains of her night of
+travel. She was determined to meet Richard looking her best.
+
+It was not until the big steamer was passing through the Narrows that
+she came on deck, and began looking about for her husband. In all that
+crowd, she knew it would take time to find him. After searching for an
+hour, she felt somewhat surprised at not seeing him. After another hour
+had passed, her surprise turned to alarm. A hasty visit to the purser,
+and an examination of the sailing list, showed her the astonishing
+truth. Richard was not on board!
+
+
+
+
+CHAPTER II
+
+
+Richard Duvall arrived in New York at half past one o'clock Thursday
+morning. Hodgman, Mr. Stapleton's secretary, had wired ahead the news of
+their coming, and the banker's limousine awaited them at the railway
+station. Fifteen minutes later they were ascending the steps of Mr.
+Stapleton's residence on Fifth Avenue.
+
+Duvall had not been to the house before. His previous interviews with
+the banker had taken place at the latter's office, in Broad Street. He
+had no time now, however, to observe the luxury of his surroundings. Mr.
+Hodgman hurried him at once to the library, and in a few moments Mr.
+Stapleton had joined them.
+
+He greeted Duvall with a nervous handshake, and thanked him for his
+prompt coming. He was clearly laboring under an intense mental strain.
+
+"Mr. Hodgman has explained my reasons for sending for you, Mr. Duvall?"
+he inquired, sinking into a great leather-covered chair.
+
+"Yes." Duvall nodded.
+
+"Then you can appreciate my feelings." He sat in silence for several
+moments, looking gloomily at the floor.
+
+"Perfectly."
+
+"The devils! I wouldn't care if they were to steal my property--money,
+securities, anything like that. I can fight them--on that basis. But my
+child! Don't you see why your coming was of the utmost importance to me?
+I don't dare move against these rascals openly. If I do, they will
+threaten to retaliate by injuring my boy, and I am powerless. Whatever I
+do, must be done secretly. No one must know that you are in my employ.
+No one must know your object in going to Paris. You see that?"
+
+"Most certainly. These fellows cannot hold you responsible for any moves
+the police authorities of Paris may make; over them you of course have
+no control. But if you make any efforts on your own account, any
+independent efforts, to recover your boy, they must by all means be made
+in secret."
+
+"Exactly. You understand, then, what you are to do?"
+
+"Yes. But first I must ask you, Mr. Stapleton, to give me some account
+of the affair. Mr. Hodgman has told me only that your son has been
+kidnapped. No doubt you have learned by this time how the thing was
+done."
+
+"What I have learned, Mr. Duvall, convinces me of the importance of
+being on the ground at once. The affair, as cabled to me by my wife, is
+preposterous--absurd!" He again gazed at the floor in gloomy
+preoccupation.
+
+"How so?" the detective inquired.
+
+"I will tell you. My boy, who, as you know, is six years old, has been
+in the habit of driving, each morning, accompanied by his nurse, from my
+house in the Avenue Kleber, to the Bois de Boulogne. On arriving in the
+Bois, it has been their habit to leave the automobile in which they
+came, and spend an hour or more walking and playing on the grass. I have
+insisted on this, because the boy needs exercise, and he cannot get it
+driving about in a motor car."
+
+"During this hour what becomes of the car?" asked Duvall.
+
+"Our orders have been, of course, for the chauffeur to wait, within
+sight and call. I believe he has done so."
+
+"Thank you. Go ahead."
+
+"On Wednesday the nurse took Jack--the boy's name is Jack--to the Bois
+as usual. She played about with him on the grass for probably an hour.
+Then she sat down to rest. Jack was standing near her, playing with a
+rubber ball. She says--and, gentlemen, my wife cables me that she
+solemnly swears to the truth of her statements--that she turned away for
+a moment to observe passing vehicles in the road--turned back again to
+the child--and found that he was gone."
+
+"Gone--but how?"
+
+"How? That's the question. Here is this woman, sitting on the grass,
+with the child, a hundred yards from the road, in the middle of a large
+field of grass--a lawn. No one is within sight. The nearest person, it
+appears from her testimony, is the chauffeur, three hundred feet away,
+in the road. The woman turns her head for a moment, looks about--and the
+boy is gone. That is the story she tells, and which my wife has cabled
+to me. Do you wonder that I call it preposterous?"
+
+"Hardly," remarked Duvall, with a grim smile. "The boy could not have
+vanished into thin air. The woman must be lying."
+
+"That, Mr. Duvall, is what I cannot understand. I cannot believe that
+the woman is lying. My wife cannot believe it. She has been in our
+employ ever since the boy was born, and is devoted to him. Mrs.
+Stapleton cables that she is completely prostrated."
+
+"But, Mr. Stapleton, you can hardly believe such a story! How could the
+child have been stolen, if her story is true? It is, as you say,
+preposterous."
+
+"I do not say that the story is true, Mr. Duvall. I say that I do not
+think that Mary is lying. She is telling what she believes to be the
+truth. She turned her head for a moment--the boy was gone. That is what
+she says, and I believe her. The question is--how is it possible?"
+
+"It isn't," Hodgman grunted.
+
+"Everything is possible, Hodgman," said the banker, reprovingly. "The
+best proof of that, in this case, is that it has happened. What means
+were used, I cannot imagine; but the apparently impossible _has_
+happened. The boy is gone!"
+
+"Is the nurse a young woman?" the detective inquired.
+
+"About thirty, I should say."
+
+"An American?"
+
+"Yes. Of Irish parentage. Her name is Lanahan--Mary Lanahan."
+
+"A New Yorker?"
+
+"She comes from Paterson, New Jersey. Her people live there."
+
+"Are there any other details--any other points of interest?"
+
+"None, so far as I know. What I have told you, is what has been cabled
+to me by Mrs. Stapleton. She is naturally in a more or less hysterical
+condition. Nothing can be accomplished here. I want you to leave by
+today's steamer. I myself, I regret to say, cannot go until Saturday."
+He passed his hand nervously across his forehead. "Only matters of the
+most vital importance could keep me here at such a time, Mr. Duvall;
+but, unfortunately, such matters confront me now."
+
+"Have you any reason to believe, Mr. Stapleton," Duvall inquired, "that
+the kidnapping is the act of persons from this side of the water? Have
+any such attempts been made in the past?"
+
+Mr. Stapleton remained silent for sometime, buried in thought. Presently
+he spoke. "I am a rich man, Mr. Duvall--a very rich man. Men in my
+position are constantly in receipt of letters of a threatening nature. I
+have received many such letters, in the past."
+
+"Was the matter of the child mentioned in any of them? Were threats made
+involving him?"
+
+"There was one such letter."
+
+"When did you receive it?"
+
+"Last fall--perhaps six months ago."
+
+"Have you the letter now?"
+
+"Yes."
+
+"May I see it?"
+
+The banker rose, went to a heavy rosewood desk at one side of the room,
+drew open one of its drawers, and removed a steel despatch box. He
+opened it with a slender key and took out a package of letters. From
+these, after some hesitation, he selected one and silently handed it to
+Duvall.
+
+The detective examined the letter carefully. It was enclosed in a cheap
+white envelope, such as are sold at all post offices, having the stamp
+printed on it. The letter itself was roughly printed in ink on a sheet
+of ruled paper evidently torn from an ordinary five-cent pad. It said:
+
+ "We demand fifty thousand dollars, to be placed in thousand-dollar
+ bills inside a cigar box and expressed to John Smith, c/o Express
+ Company, Paterson, N. J., next Monday afternoon. The man who will
+ call for the package on Tuesday will know nothing about the matter,
+ and if you arrest him, you will find out nothing. Keep this to
+ yourself and do as we say, if you value the safety of your child."
+
+There was no signature to the letter. Duvall read it through with great
+care, then turned to Mr. Stapleton.
+
+"You have observed, I suppose, that the place to which the money was to
+be sent, Paterson, New Jersey, is the home of your child's nurse, Mary
+Lanahan."
+
+Mr. Stapleton started. "I confess," he said "that, in the agitated state
+of mind into which this affair has thrown me, I had completely
+overlooked the coincidence. What do you infer from it?"
+
+"Only this, Mr. Stapleton, that Mary Lanahan may know more about this
+matter than she is willing to let on. I must keep this letter for the
+present."
+
+"Very well." The banker nodded. "It may prove a valuable clue."
+
+"Possibly. And further, Mr. Stapleton, I shall not sail by today's
+steamer."
+
+"But--why not?" Stapleton sat up in his chair in surprise. "You will
+lose two days."
+
+"I do not think they will be lost. I must make some investigations in
+Paterson, before I leave here. Please give me, if you can, the address
+of Mary Lanahan's parents."
+
+Mr. Stapleton frowned. "I am not sure that I can do so, Mr. Duvall. My
+wife has charge of these matters. But I recollect having heard that her
+father, Patrick Lanahan, is a florist in a small way, and no doubt you
+can readily locate him. But I fear you will be losing valuable time."
+
+Duvall rose. "I feel, as you do, Mr. Stapleton, that I should be in
+Paris at the earliest possible moment; but I think you will agree with
+me that some investigations on this side before I go are absolutely
+necessary, and may prove of inestimable value afterwards."
+
+Mr. Stapleton was silent for several minutes. Presently he raised his
+head. "Under the circumstances, Mr. Duvall, I am forced to admit the
+truth of what you say. Conduct your investigations as quickly as
+possible, however; for we must positively sail by Saturday's boat."
+
+"I shall be ready then." Duvall took up his hat. "Now I think I had
+better get a few hours' sleep, and in the morning I will make an early
+start for Paterson." He bowed to the banker and Mr. Hodgman. "Good
+night, gentlemen. I shall see you both on Saturday morning. The steamer
+sails shortly after noon, I believe. Suppose I come here at ten o'clock,
+and let you know what I have learned?"
+
+Mr. Stapleton rose. "If I receive any further news of importance from
+Paris, Mr. Duvall, I will advise you at your hotel. Where are you
+stopping?"
+
+Duvall gave the name of a Times Square hotel at which he usually
+stopped, and with a quick "good night" left the house.
+
+It was shortly after nine o'clock the next morning when he descended
+from the train at Paterson, and going to a nearby drug store, consulted
+the directory for the address of Patrick Lanahan. He found it without
+difficulty, and, by means of an electric car, was soon before the
+florist's door.
+
+The place was situated on the outskirts of the town, and consisted of a
+small, rather mean-looking cottage, from which spread out on each side,
+like the two wings of an aeroplane, the long glass greenhouses.
+
+A little gate opened to a short brick path, leading to the front door of
+the house.
+
+Duvall went up the path and rang the door bell. A wholesome-looking
+Irish woman, of perhaps fifty, opened the door, and, in response to his
+questions, told him that her husband, Patrick, was out in the garden at
+the rear of the house, busy with his plants.
+
+She directed the detective along a narrow areaway at the side of the
+house, and in a moment reappeared at the back door.
+
+"Pat," she called. "Oh, Pat! Here's a gentleman to see you."
+
+A short, heavy-set man, with gray hair and mustache and a ruddy and
+weatherbeaten face, arose from among a litter of flower pots and bulbs.
+
+"What can I do for you, sir?" he asked, coming forward and wiping his
+hands upon his overalls.
+
+The detective studied the man before him intently. The honest and
+clear-looking eyes told him nothing that was not favorable.
+
+"I came to ask you a few questions, Mr. Lanahan."
+
+"Questions, is it? About what?" The blue eyes showed a sudden flare of
+suspicion.
+
+"About yourself, and your family."
+
+"Who may you be, then? Is it the tax man?"
+
+Duvall smiled. "Not the tax man," he said. "I represent a firm of
+lawyers in Washington. My name is Johnson."
+
+Lanahan, still suspicious, pointed to a couple of kitchen chairs that
+stood on the brick-paved yard beneath a trellis covered with hop vines.
+"Sit down, sir. I'll have a smoke, if you don't mind." He began to fill
+his short clay pipe. "What would lawyers in Washington be wantin' with
+me?"
+
+"That is what I wish to find out, Mr. Lanahan. We--my firm--have been
+advised that a certain Michael Lanahan, of Dublin, recently died,
+leaving a large estate. We are trying to find his heirs. Tell me
+something about yourself and your family."
+
+The look of suspicion and reserve which the old man had up to this time
+shown faded from his face, and was replaced by a smile of incredulity.
+"Money, is it?" he laughed. "Mary--that's my wife--has been seein'
+bubbles in her tay for the week past. What is it you would know?"
+
+"Are you from Dublin?"
+
+"Me father was. I was born right here in Jersey, meself."
+
+"What was his name?"
+
+"Patrick, the same as me own. But he had a brother, Mike."
+
+"Ah. It may be the same." Duvall pretended a sudden interest. "His
+business?"
+
+"Mike's? Faith--I never heard he had any, lest it was drinkin' all the
+good liquor he could lay his hands on."
+
+Duvall pretended to make a series of entries in his notebook. "Now
+about yourself, Mr. Lanahan. Have you any children? Of course, should
+there be any money coming to you, they would share in it."
+
+"Children, is it? I have two."
+
+"Boys?"
+
+"One is a boy--a man be now, I should say. He's in the city--workin'.
+His name is Barney."
+
+"What does he do?"
+
+Lanahan looked up with a quick frown. "The last I heard tell, he was
+tendin' bar, Mr. Johnson--over at Callahan's saloon, on the Bowery. He's
+wild--wild--like me uncle Mike, I should say."
+
+"And the other?"
+
+The old man's face took on a contented look. "The other is me daughter
+Mary, bless her. She's nurse in the family of old man Stapleton, the
+millionaire."
+
+Duvall closed his book. "I see," he remarked, pleasantly. "She's not
+married, I suppose?"
+
+"Mary? Divil a bit! For a time, she was sweet on a French chuffer that
+worked for Mr. Stapleton; but the fellow's gone, now, and she's clane
+forgot him. That was near a year ago."
+
+"Ah, yes. Do you happen to remember his name?"
+
+"Alphonse, it was--Alphonse Valentin, or some such joke of a name. A
+comic valentine he was, too, with his dinky little mustache and his
+cigarettes." He laughed loudly. "Imagine my Mary, married to a gink like
+that!"
+
+Duvall replaced his notebook in his pocket and rose. "I'm mightily
+obliged to you, Mr. Lanahan. We will advise you at once, if our
+investigations show that you are related to the Michael Lanahan whose
+fortune is in our hands. I'm obliged to you for your courtesy."
+
+The florist nodded. "You're welcome, sir. I guess them Lanahan's must be
+a different breed. I never heard tell of any of my people makin' any
+fortune. Good day, sir." He turned to his work, chuckling.
+
+Duvall rode back to the station, and took the first train for New York.
+It was clear that Mary Lanahan's parents had nothing in common with
+blackmailers and kidnappers. Their honesty was as evident as the
+blueness of their eyes, or the redness of their hair. But the
+information about Alphonse Valentin, the chauffeur, and Barney, Mr.
+Lanahan's son, seemed more promising.
+
+It was close to one o'clock when Duvall arrived at Callahan's saloon, on
+the Bowery, near Canal Street. Here a disappointment awaited him. Barney
+Lanahan had thrown up his job and left two months before. Callahan had
+no idea where he had gone. He had not been about the place since. A
+negro porter volunteered the information that he had seen the man
+entering the Broadway saloon of an ex-prizefighter some weeks before;
+but, beyond that, Duvall could learn nothing.
+
+After a hasty luncheon he went to his office on Union Square, where his
+unexpected appearance caused his assistants unlimited surprise. He
+directed them to locate Barney Lanahan at the earliest possible moment.
+He then called up Mr. Stapleton's secretary, Mr. Hodgman, and inquired
+about the chauffeur.
+
+Mr. Hodgman informed him that the banker had employed Valentin in Paris
+some eighteen months previous, and had brought him to this country,
+where he had remained in his employ for about six months. He had been
+discharged, through some dishonesty in the matter of purchasing
+supplies, and nothing further had been seen or heard of him.
+
+Duvall, on receiving this information, proceeded at once to the office
+of the French line, and asked permission to inspect their passenger
+lists for the past year. He concluded that if Valentin had anything to
+do with the kidnapping of Mr. Stapleton's boy, he was, in all
+probability, in Paris, and, if so, would almost certainly have crossed
+by this line. He was therefore not at all surprised to find the name of
+Alphonse Valentin among those sailing during the preceding March.
+
+There was little more that he could accomplish, now, beyond writing a
+long letter to Grace, whom he naturally supposed to be patiently
+awaiting his return in the country. He had a short interview with Mr.
+Hodgman in the evening, and was lucky enough to secure a photograph of
+Alphonse Valentin, the chauffeur, taken at the steering wheel of his
+machine. The car had, it seemed, been photographed, along with a party
+of guests, by a friend of Mr. Stapleton's with a leaning toward amateur
+photography. Duvall placed the photograph among his belongings with a
+smile of satisfaction. He felt that his delay had been by no means
+unprofitable.
+
+One other step he took, before leaving. Accompanied by Mr. Hodgman, he
+made a careful inspection of the room which had been occupied by the
+nurse, Mary Lanahan, at the Stapleton house. The results were
+distressingly meager. All the woman's belongings she had evidently taken
+with her, on going abroad. There appeared to be nothing which would
+afford the slightest clue to her character or habits.
+
+Mr. Hodgman turned to the door with an impatient frown. "Nothing here,"
+he growled, and was about to leave the room.
+
+"Nothing much," said Duvall, glancing carelessly at the wooden edge of
+the bureau. "This woman, Mary Lanahan, is evidently an up-to-date sort
+of person."
+
+Hodgman paused. "Why do you say that?" he asked.
+
+"Smokes cigarettes, I see."
+
+"That so. How do you know?"
+
+Duvall smiled. "Too simple even to mention, Mr. Hodgman. See those burns
+on the varnish?" He pointed to a number of spots along the edge of the
+dresser. "Always find them somewhere about, where there's a cigarette
+smoker." He gazed out of the window for a moment. "Rooms tell a great
+deal about the personality of the people who have occupied them. For
+instance, I've never seen this Lanahan girl, but I know that she's not
+over five feet four, that she has light hair, that she reads in bed,
+that she writes with a stub pen, and that she's a Roman Catholic.
+Furthermore, she is left handed, inclined to be vain, wears her hair in
+waves, or curls, in front, is fond of the theater, and has a long narrow
+scar on the palm of her left hand."
+
+He chuckled quietly, as he saw Mr. Hodgman's look of amazement. "All
+very simple--quite elementary, in fact. I won't even bother to tell you
+how I know--just little things here and there about the room. Here's one
+of them," he said, as he picked up a rusty pen point from the desk.
+"That shows she uses a stub, of course; but the way the point is worn
+also proves that she's left handed. And here's another." He pointed to
+the electric bulb which hung over the head of the bed. "Nobody would use
+that light, except to read by in bed. The others in the room are more
+than sufficient for purposes of illumination. Yet the lamp has been used
+continuously, as its condition shows. See how blackened the glass
+is--and notice also how the white enamel of the back of the bed is worn
+off, just under the lamp. That's from propping a pillow against it,
+night after night." He turned toward the door. "Of course, those things
+aren't of any value, probably, in this case; but I can't help noticing
+them. Force of habit, I suppose."
+
+When Duvall arrived at the Stapleton house on Saturday morning, he found
+the banker somewhat disturbed by a cablegram he had just received. "Mary
+claims attempts made to poison her. Will recover. Come at once," it
+read.
+
+The detective appeared to be somewhat astonished, on reading the
+cablegram. "Looks as though somebody was afraid she might be going to
+talk," he remarked. "The sooner we arrive in Paris, now, the better."
+
+
+
+
+CHAPTER III
+
+
+Grace Duvall's first inclination, on finding herself en route for
+Europe, without her husband, was to send him a wireless, advising him of
+her movements. Then she decided, for several reasons, not to do so.
+Chief among these was the fear that such a startling piece of news would
+be likely to cause him a great deal of unnecessary anxiety. She knew
+that she could never hope to explain matters, within the limits of a
+marconigram. And then, too, it was highly inadvisable, she knew, to
+mention in a wireless message the real reason which had caused her to
+leave home.
+
+So she decided to make the best of the matter, realizing that within a
+few days, she would see Richard in Paris, and explain everything to his
+satisfaction.
+
+Immediately on reaching Paris, she drove to the office of the Prefect of
+Police, and sent in her card to Monsieur Lefevre. She thought it
+possible that he would expect her, as his agent in Washington would no
+doubt have communicated with him. Nor was she mistaken.
+
+He rushed into the anteroom as soon as he received her card, and
+embraced her with true Gallic fervor, kissing her on both cheeks until
+she blushed. Then he drew her into his private office.
+
+"Where is your husband?" he asked, eagerly, as soon as Grace was seated.
+
+"I--I do not know. Probably on his way to Paris."
+
+"But--my dear child! Did he not then come with you?"
+
+"No. He--he had other business."
+
+"Other business! But I understood that he had temporarily retired." The
+Prefect seemed greatly astonished.
+
+"So he had; but an old friend, Mr. Stapleton"--
+
+Lefevre did not allow her to finish. "Stapleton!" he fairly shouted. "He
+is employed by him? Mon Dieu!"
+
+"Why not?" asked Grace in surprise.
+
+"But--it was for that very case that I desired his assistance. And by
+this Stapleton, who cables that the whole police force of Paris are a
+lot of jumping jacks! Sacre! It is insufferable!"
+
+"You wanted my husband for the same case?"
+
+"Assuredly! What else? The child of this pig of a millionaire is
+stolen--what you call--kidnapped! We have been unable to find the
+slightest clue. I am in despair. My men assure me that it is the work of
+an American gang. I conceive the hope that Monsieur Duvall may know
+these men--that he may be in possession of information that will lead to
+their capture. This rich American, he has spoken with contempt of the
+Paris police. The efficiency of my office is questioned. My honor is at
+stake. I send for my friend Duvall, to assist me, and--sacre!--I find
+him already working for this man who has insulted me. It is monstrous!"
+
+Grace could scarcely repress a smile. How excessively French the Prefect
+was, after all. "My husband did not know, when he agreed to take the
+case for Mr. Stapleton, that you wanted him. He does not know it now. He
+has not yet received your message."
+
+"Then he does not know that you are in Paris?"
+
+"No. I thought he would be crossing on the same boat. When I found that
+he wasn't, my first thought was to send him a wireless. Then I realized
+that I couldn't do so, without saying something about the business that
+had called me to Paris--without, in fact, mentioning you. I feared to do
+this--for there are so many people nowadays tapping the wireless. I
+thought it better to keep the matter a secret."
+
+"And you did quite right. I wanted your husband to take up this case,
+quite independently, and without it being known to anyone that he was in
+my employ." He paused for a moment in deep thought. "No doubt his
+employment by Mr. Stapleton is to be kept equally secret."
+
+"I suppose so. He asked me not to say anything about it. I had to tell
+you, to explain matters."
+
+"And he doesn't know that you are in Paris?" The Prefect gave a sudden
+laugh. "_Ma foi!_--what a joke!"
+
+"A joke?"
+
+"Assuredly! Don't you see? I am going to ask _you_ to take up this case,
+yourself. I must use every means to recover the child of this Stapleton,
+before others do so for him. My professional pride will not permit me to
+be beaten. If I can't have your husband, at least I shall have you."
+
+"But--I shall be working in opposition to him."
+
+"Not in opposition. You will both have the same object in view--the
+recovery of Mr. Stapleton's boy. Whichever of you does so first, the
+result will be the same--the boy will be restored to his parents. But I
+want you, my child, to be the one to do this."
+
+"But, Monsieur Lefevre, I could not hope to accomplish anything--where
+trained men have failed."
+
+"Who knows? I remember well the assistance you gave us, in the matter of
+the ivory snuff box. Without your help, we should never have recovered
+it. I have faith in a woman's intuition. You will find this child for
+me, and give your husband the surprise of his life."
+
+"But," said Grace, smiling mischievously at the prospect which opened
+before her, "suppose he should see me?"
+
+"You must disguise yourself somewhat. Change the color of your hair; it
+is easily done--here in Paris." The Prefect laughed. "A slight
+alteration in appearance only will be necessary. And do not recognize
+your husband, should you meet him face to face. That is most important."
+
+"Why?"
+
+"Because, should he become convinced that it is really you, I fear he
+would insist upon your dropping the case entirely, and that would not
+suit my plans at all. Come, my child." The Prefect's eyes twinkled with
+amusement. "Do this thing for me. It will be a little joke, between us.
+The honeymoon detectives, I called you, once. What an amusing thing,
+that now you should be working in competition with each other, on the
+same case!" He began to laugh heartily.
+
+"Well," said Grace, her sense of mischief getting the better of her,
+"now that I'm here, I suppose I might as well keep busy. Richard won't
+be here for two days, and I may find out something in that time."
+
+"Excellent!" The Prefect clapped his hand smartly upon his knee. "You
+have two days' start. In two days, much may be accomplished. Come, let
+us go over the case in detail."
+
+An hour later, Grace left the Prefect's office in a taxicab, having
+arranged to have her baggage sent to Monsieur Lefevre's house, where she
+was to stay while in Paris. Her previous acquaintance with Madame
+Lefevre made this an ideal arrangement. She was to pose as a friend, in
+Paris on a visit.
+
+She ordered the driver of the taxicab to take her to Mr. Stapleton's
+house in the Avenue Kleber.
+
+She found Mrs. Stapleton to be a very pretty and stylish woman of
+thirty; whose beauty, however, was sadly marred by the intense suffering
+through which she was passing. The poor creature had scarcely slept for
+over a week, and her distress was pitiable.
+
+She answered Grace's questions as well as she could, under the
+circumstances. There was, after all, little to say. The nurse, it
+appeared, stuck to her story--that the boy had vanished, in the
+twinkling of an eye, while her back had been turned for but a few
+moments. Mrs. Stapleton could offer no explanation--attempted none.
+
+"It is all so mysterious--so terrible!" she cried. "Poor Mary--she is
+too ill to see you, I fear, or I would have her tell you the story
+herself."
+
+"Too ill?" inquired Grace, who had come more to question the maid, than
+Mrs. Stapleton. "What is the matter with her?"
+
+"They tried to poison her--last Friday."
+
+"They? Who?"
+
+"I do not know. She went out for a walk. The poor woman was half dead,
+from nervous exhaustion and loss of sleep. She tells me that she stopped
+to get a cup of chocolate at a cafe in the Rue St. Honore. After that
+she came back to the Champs Elysees, and sat upon a bench. She began
+suddenly to feel deathly ill, and, calling a cab, was driven home. When
+she arrived here, she was unconscious, and had to be carried to her room
+by the servants. She has been in bed ever since. I am glad to say,
+however, that she is better, and I think she could see you, by morning."
+
+Grace left the Stapleton house, feeling somewhat baffled. The more she
+heard of this curious affair, the more inexplicable it seemed. She had
+hoped to visit the scene of the kidnapping, in company with the nurse,
+and examine the spot with her own eyes. This she now realized she could
+not do until the following day. She was walking in the direction of the
+Arc de Triomphe, revolving the affair in her mind, when a young man,
+evidently a Frenchman, of good appearance and not unpleasant face, came
+up beside her, bowed politely, and in excellent English asked her
+regarding Mary Lanahan.
+
+"Miss Lanahan--is she better?" he inquired.
+
+"Who are you, monsieur?" asked Grace, suppressing her inclination to
+resent the man's action, in her hope that she might learn something from
+him of value. His question showed Grace at once that he was acquainted
+with at least one member of the Stapleton household.
+
+"I am a friend of Miss Lanahan's," the man replied. "I hear that she is
+ill. I saw you enter and leave the house, and I ventured to ask you if
+she is better."
+
+"I was told that she is. I did not see her."
+
+A peculiar expression crossed the young man's face; but Grace could not
+determine, so fleeting was it, whether it indicated pleasure or
+disappointment.
+
+They walked along in silence for a few moments, and had almost reached
+the arch, when a ragged little urchin, a veritable Paris gamin, came up
+to Grace's companion and thrust a crumpled bit of paper into his hand,
+then darted off, whistling shrilly.
+
+The man looked after him a moment, then examined the note. Whatever its
+contents, they made a startling impression upon him. He looked about, an
+expression of fear upon his face, turned to Grace with a hurried bow,
+and a quick good evening, and at once walked off in the opposite
+direction at full speed, at the same time fumbling in the breast pocket
+of his coat, as though searching for something in it. In his efforts, he
+dropped several papers to the street. Grace watched him as he picked
+them hurriedly up and moved off into the gathering darkness.
+
+She fancied that one of the bits of paper had escaped his notice, and,
+on going back to the spot, found that she was correct. A small visiting
+card lay upon the sidewalk. She picked it up, and read the name as she
+walked away. It was Alphonse Valentin, Boulevard St. Michel.
+
+Grace slipped the card into her pocketbook. The man's name meant nothing
+to her--she fancied that he was some friend of Miss Lanahan's, concerned
+about her condition. Yet why did he not inquire for her at the house, in
+the ordinary way? And why should the note, handed to him by the street
+urchin, have caused him such evident alarm?
+
+She glanced at her watch, and saw that it was close to seven o'clock.
+She had intended to return to Monsieur Lefevre's for dinner; but a
+sudden determination to find out more about this man Valentin caused her
+to proceed at once to a hotel near the Louvre, where she ate her dinner
+alone.
+
+An hour later she descended from a cab at the number on the Boulevard
+St. Michel, which was inscribed upon Alphonse Valentin's card.
+
+The place was a dingy old building, the main floor of which was occupied
+by a dealer in cheese. A narrow doorway at one side gave access to the
+upper floors. Grace rang the bell, and waited in some trepidation. This
+going about Paris at night was rather an unusual experience. She thought
+of the simple joys of her life at home, and for a moment regretted that
+she had not stayed there. The opening of the door interrupted her
+thoughts.
+
+The woman who stood in the hallway regarded her without particular
+interest, and inquired her business. "I wish to see Monsieur Valentin,"
+said Grace.
+
+"He is not in."
+
+"Then I will wait. I must see him. He expects me."
+
+The woman shrugged her shoulders. "As you wish, mademoiselle. Come this
+way." She led Grace up a flight of stairs, and indicated a door at the
+rear of the upper hall. "That is Monsieur Valentin's room." Then she
+turned away, apparently quite indifferent as to whether Grace entered or
+not.
+
+The latter placed her hand on the knob of the door, and slowly pushed it
+open. The room was dark; but the light from the rear windows rendered
+the objects within it faintly visible. Upon the table stood a lamp. With
+some difficulty the girl succeeded in finding a match, and lit it.
+
+The light of the lamp disclosed a rather large room, with a small
+alcove in the rear, containing a bed. The alcove was curtained off from
+the main room. Grace, however, did not spend much time in examining her
+surroundings. A photograph on the table at once attracted her
+attention--not because it represented anyone she knew, but because,
+across the bottom of it, was inscribed, in a feminine hand, "Mary
+Lanahan."
+
+She had just completed her examination of the photograph, when two other
+objects attracted her attention. One was a crumpled bit of paper, upon
+which a few words were scrawled in lead-pencil. They were, "I am
+suspicious of Francois. Watch him." The note was unsigned.
+
+The third object upon the table which caught Grace's attention was a box
+of cigarettes, open, and nearly full. They were small gold-tipped
+affairs, of the kind generally used by women, and it was this
+peculiarity that at first attracted her attention. She thought it
+strange, that a man should use such cigarettes. She looked at the box,
+and observed that they were of American make.
+
+Illustration: Once inside he made without hesitation for the table,
+picked up the box of cigarettes and thrust it into his pocket.
+
+Idly she took up one of the cigarettes, and held it in her fingers. She
+read the name of the brand, printed upon the paper wrapper, and was
+about to drop it back into the box, when she heard a curious rasping
+noise outside one of the rear windows. It sounded as though someone were
+climbing the wall of the house. Instinctively she shrank back and
+concealed herself behind one of the curtains which hung before the
+alcove door.
+
+The rasping and scraping continued for some little time, and presently
+Grace, peering through the space between the curtains, saw a face appear
+at one of the windows. It was a determined face, heavily bearded, dark,
+evil looking. Its gleaming eyes swept the room with cautious care, then,
+evidently satisfied that it was unoccupied, their owner began
+noiselessly to raise the sash of the window.
+
+It was slow work. Several minutes passed before the man succeeded in
+raising the sash sufficiently to permit him to crawl into the room. Once
+inside, he made without hesitation for the table, glanced over its
+contents, picked up the box of cigarettes and thrust it into his pocket,
+and then, without paying the least attention to anything else, walked
+quickly to the door of the room and passed out into the hall.
+
+The girl waited for a moment, then stepped into the light. As she did
+so, she realized that she held in her hand one of the gold-tipped
+cigarettes she had taken from the box. She quickly thrust it into her
+pocketbook, and, with sudden decision, left the room and descended the
+stairs. She had an instinctive feeling that the man who had stolen the
+cigarettes was in some way connected with the kidnapping of the
+Stapleton child. She determined to follow him, leaving the interview
+with Alphonse Valentin to another time.
+
+She left the house, and saw the man going down the Boulevard some fifty
+feet in advance of her. She walked along after him, pretending to be
+totally uninterested in her surroundings, while at the same time keeping
+a sharp watch upon him.
+
+He seemed in somewhat of a hurry, and walked briskly along, looking
+neither to left nor to right. Grace kept as close to him as she dared,
+without running the risk of detection. The walk was a long one. When
+half an hour had passed, the girl saw that they were entering the Champs
+Elysees. The Seine they had long since crossed by the Pont Neuf. Up the
+brilliantly lighted avenue they went, toward Arc de Triomphe. At the
+corner of the Avenue Kleber, the man turned to the left. Grace followed,
+wondering where the chase would lead next. To her astonishment, the man
+disappeared suddenly through a gate which formed the servants' entrance
+of one of the stately houses which fronted on the avenue. She looked up.
+It was the house of Mr. Stapleton!
+
+
+
+
+CHAPTER IV
+
+
+On the day following that upon which she arrived in Paris, Grace Duvall
+sallied forth, determined to find out two things--first, the position
+occupied by Alphonse Valentin in the affair of the kidnapping; secondly,
+the identity of the man who had stolen the box of cigarettes from
+Valentin's room, and gone with them to the house in the Avenue Kleber.
+The latter incident seemed trivial enough, at first sight; yet she
+reasoned that no one would risk arrest on the score of burglary, to
+steal anything of such trifling value, without an excellent reason.
+
+She had a short conference with Monsieur Lefevre, before she left the
+house, and told him of the events of the previous night. The Prefect
+seemed greatly interested.
+
+"Could you identify the man who stole the cigarettes?" he asked.
+
+"Easily. I had a splendid view of his face."
+
+"Then go to Mr. Stapleton's house and take a look at all the servants.
+You may find him among them."
+
+"I had intended to do so, this morning."
+
+The Prefect smiled. "I do not know what your investigations will lead
+to, but they seem promising. I have a dozen men working on the case; yet
+so far they have not made the least progress. Their efforts, however,
+are directed toward finding the child. They are searching the city with
+the utmost care. We believe that by discovering the missing boy, we
+shall also find the persons who committed the crime."
+
+"Have you no one under suspicion?"
+
+"No one. The nurse, Mary Lanahan, is of course being closely watched;
+also the chauffeur, Francois. My men report, however, that he gave them
+the slip for an hour, last night. I have an idea that he may prove to be
+the one who took the cigarettes."
+
+"Can you imagine any reason for his having done so?"
+
+"I confess, my child, that I cannot. It seems utterly absurd; unless,
+indeed, there was something else concealed in the box."
+
+"What?"
+
+The Prefect laughed. "I cannot imagine. But if you can identify the
+man, we shall no doubt find out. As for the matter of Alphonse Valentin,
+we have already had him under observation. So far as we can learn, he is
+merely a chauffeur, out of work, who seems to be somewhat in love with
+the nurse."
+
+"Then his actions have not been suspicious, during the past week?"
+
+"Not in the least. He has hung around the Stapleton house for several
+days, asking for news of the Lanahan woman; but that is all. We
+attribute his actions to a natural anxiety over her illness."
+
+Grace left the house, by no means satisfied with the progress she was
+making. Her interview with Mary Lanahan, and subsequent visit to the
+scene of the crime, told her nothing she had not already known. Her
+greatest disappointment, however, came when she had Mrs. Stapleton bring
+in Francois, ostensibly to question him about his part in the affair.
+She saw at once that he was not the man who had broken into Alphonse
+Valentin's room on the night before. This man had been heavily bearded
+and tall. Francois was smooth shaved and rather short. Mrs. Stapleton
+assured her that none of her servants resembled in the least her
+description of the burglar. She left the house, greatly dissatisfied,
+after satisfying herself that this was the case.
+
+Her visit to the house of Alphonse Valentin that afternoon was
+productive of no greater results. The man was out. The woman who opened
+the door--the same one who had admitted her the previous
+evening--regarded her with ill-concealed suspicion, and informed her
+that she had no idea when her lodger would return. Grace left,
+determined to try again the following day.
+
+Throughout the whole evening she hung about the Stapleton house, hoping
+again to see the man with the heavy beard who had disappeared within the
+night before; but he did not put in an appearance. Grace began to feel
+discouraged. She thought of her lilac bushes, at home, of Aunt Lucy
+feeding the chickens, of the dogs, the sweet call of the wood robins
+among the poplar trees on the lawn, and half wished that she had stayed
+at home and left to Richard the apparently hopeless task of finding the
+abductors of little Jack Stapleton.
+
+What, after all, could she hope to do, where the entire police force of
+Paris had failed? The thing was absurd. Monsieur Lefevre had overrated
+her abilities. She heard the sound of church bells, striking the hour of
+ten, and decided to go home and forget the whole affair until tomorrow.
+Tomorrow--the day Richard must arrive! How she longed to be with him!
+This stupid interruption of their honeymoon seemed peculiarly cruel, now
+that over a week had elapsed since they had seen each other. She
+wondered if she would meet him, the next day. Then she thought of her
+changed appearance, of her hair, dyed a jet black, and worn in a new and
+to her mind unbecoming fashion, of her darkened complexion, her
+extremely French costume, her heavy veil, and laughed. If Richard did
+see her, here in Paris, when he fully believed her to be peacefully
+tending her flower beds at home, he would never believe the evidence of
+his senses.
+
+She was strolling toward the Champs Elysees, lost in thought, when
+suddenly she heard the soft throbbing of a high-powered motor car, as it
+came up the street behind her. She turned and glanced toward it; but the
+brilliant glare of the electric headlights blinded her. She could see
+nothing, except that the car was moving very slowly.
+
+Suddenly it stopped, almost abreast of her, and a tall man leaped to the
+sidewalk. Before she had an opportunity so much as to glance in his
+direction, he came swiftly up behind her, threw his arm about her neck,
+and choked her into unconsciousness. Her last sensation was of being
+lifted bodily into the already moving car, and then the feeling of rapid
+motion, quickly blotted out by the coming of insensibility.
+
+When she returned to consciousness, it was broad daylight. She lay upon
+a small wooden bed, in a low-ceilinged little room, the only furniture
+of which was a small chest of drawers and a chair. Upon this chair sat a
+large man, his face so thoroughly hidden by a mask that his features
+were quite unrecognizable. He was regarding her with keen scrutiny.
+
+"Oh--what--where am I?" she gasped.
+
+The man hesitated for a moment, then slowly spoke. "Where you are,
+mademoiselle, is of no importance. Attend to what I have to say."
+
+Grace made no reply. There seemed nothing that she could say. She sat up
+and gazed at the man, half dazed. Her head swam. She felt that she had
+been drugged.
+
+"Ten days ago," the man went on, in a cold and menacing voice, "the
+child of Monsieur Stapleton was taken from his nurse in the Bois de
+Boulogne. You are trying to find that child."
+
+"But--" Grace made a movement of protest.
+
+"It is useless to deny it. You have been watched."
+
+Grace gasped in silence.
+
+"I desire to send a message to the boy's father, and I have chosen you
+to take it to him. I have selected you, because to send one of my own
+men would doubtless result in his arrest. That is why you have been
+brought here."
+
+"The--the child is safe?" asked Grace.
+
+"Perfectly. You shall see for yourself." He motioned to the window.
+
+Grace rose, and looked out. The view comprised a bit of garden,
+surrounded by bushes. She could see nothing beyond--nothing that would
+enable her in any way to identify the place. On the tiny plat of grass
+in the garden sat a child--a little girl, playing with a small black and
+white spaniel. Her dark hair was drawn tightly beneath a pink sunbonnet.
+Her dress, her whole appearance, was that of a peasant child.
+
+Grace turned from the window, bewildered. "I see nothing," she said,
+"except a little girl--"
+
+"That is the child of Monsieur Stapleton," the man said. "Now attend to
+the message."
+
+She sat down again, wondering.
+
+"Tell the boy's father this: He will leave his house tomorrow evening,
+in his automobile, at eight o'clock. He will bring with him, in a
+package, the sum of five hundred thousand francs--one hundred thousand
+dollars. He will have with him, in the automobile, no one but himself
+and his chauffeur. He will leave Paris by the Porte de Versailles, and
+drive along the road to Versailles at a speed of twelve miles an hour.
+Somewhere upon that road, among the many automobiles that will pass him,
+will be one, from which a blue light will flash, as it approaches him.
+It will also slow up. He will toss the package of bank notes into that
+car, and drive on. If the package contains the sum of five hundred
+thousand francs, he will find his child at his house, upon his return.
+If not, or if these instructions are not carried out to the letter--if
+there is any attempt made at pursuit--the child will not be there, and
+you can tell him that he will be given but one more chance. After that,
+the boy will die."
+
+The man in the mask made this gruesome statement with the utmost
+coolness.
+
+Grace listened, aghast at the cruelty of his words, and at the same time
+struck by the extreme ingenuity of the plan. To catch the perpetrators
+of the crime, under these circumstances, seemed impossible. A rapidly
+moving automobile--one of a hundred. An instant's flash of a blue light
+in passing--the tossing into the car of the money--and it would speed
+away into the darkness, beyond any hope of detection. Should Mr.
+Stapleton have others in his car--should he have his car followed by a
+second, containing armed men, the occupants of the kidnapper's machine
+would no doubt refuse to give the signal, and nothing would be
+accomplished. It would be impracticable to line the road, for a possible
+distance of twenty miles, with gendarmes, nor could their presence
+accomplish anything, beyond putting the kidnappers on guard, and
+preventing the carrying out of the plan.
+
+The weakest point in the whole scheme seemed, to Grace at least, the
+delivery of the child to Mr. Stapleton, provided he paid the money
+demanded. Just how that was to be accomplished, without subjecting the
+person who brought the boy to arrest, she did not see. A moment's
+reflection, however, showed her that a stranger might be employed, at
+any point, who for a few francs would agree to take the child to the
+house. She turned to the man before her with feelings not devoid of
+admiration.
+
+"How can Mr. Stapleton know that you will do as you say?"
+
+The man shrugged his shoulders. "That is a chance he must take. If he
+does not believe that the child will be delivered to him, provided he
+pays the money, he had better not pay it. But if he does his part, I
+shall do mine--and this I swear by the memory of my mother!"
+
+Grace shuddered. A wretch of this sort, talking about the memory of his
+mother! "Very well," she said quietly, "I will take your message."
+
+"Good! You will not leave here, of course, until it is dark--tonight.
+You will be blindfolded, and conducted to some point in the city. From
+there, you can make your way to Monsieur Stapleton's house." He rose,
+and went toward the door. "Make no attempt to escape. It will be
+useless. Any attempts on the part of the police to interfere with the
+plan I have outlined will result in nothing. Food will be sent in to you
+at once. Good morning."
+
+It was close to ten o'clock that night, as nearly as Grace could judge,
+when she was led a considerable distance blindfolded, to a closed
+automobile, and driven away. She could form no idea of her whereabouts.
+The car continued on its way, for over an hour. Once she attempted to
+snatch the bandage from her eyes; but a hand was placed upon her arm by
+another occupant of the machine, and a low voice warned her to desist.
+
+After an interminable ride, the car suddenly stopped, and she felt the
+man at her side slip away from her and open the door. Instantly she
+snatched the bandage from her eyes. The man had disappeared. She stepped
+to the sidewalk, and looked about. She was standing upon a brightly
+lighted street, which seemed somehow familiar to her. The man on the box
+of the cab glanced down at her with a look of curious interest. She saw
+his face clearly, in the light of the street. It was the heavily bearded
+man whom she had seen take the box of cigarettes from the room of
+Alphonse Valentin two nights before.
+
+Grace stood with the bandage which had encircled her eyes, still in one
+hand. Suddenly she saw a dark figure uncoil itself from the rear of the
+car, and drop noiselessly to the pavement as the machine started off.
+She gave a low cry of surprise. The man came up to her, a grim smile
+upon his face. It was Alphonse Valentin.
+
+
+
+
+CHAPTER V
+
+
+John Stapleton, the millionaire banker, accompanied by Richard Duvall,
+arrived in Paris early in the afternoon, and went at once to the
+former's house in the Avenue Kleber.
+
+Upon their arrival, Duvall waited for sometime, while the distressed
+husband and wife were closeted together upstairs. At last they descended
+to the library, and Duvall was presented to Mrs. Stapleton.
+
+The joy which her husband's arrival had caused her sent a new glow of
+hope to her careworn cheeks, and she greeted the detective most
+cordially. Clearly she felt that now something would at last be done, to
+find her missing child.
+
+Duvall's first questions related to Mary Lanahan, the nurse. He was
+relieved to find that she had quite recovered from her sudden illness.
+
+"Will you kindly have her brought here, Mrs. Stapleton?" he asked. "I
+would like to question her."
+
+In a few moments the nurse appeared. She was an extremely good-looking
+girl, smart and well dressed. Duvall recognized in her frank face, her
+clear blue eyes, the same appearance of honesty which had impressed him
+during his interview with Patrick Lanahan, her father.
+
+"Mary," said Mrs. Stapleton, "this is Mr. Duvall. He is trying to find
+Jack for us. Tell him your story."
+
+The girl turned to Duvall, who had risen. "I can hardly expect you to
+believe what I am going to say, Mr. Duvall, yet I assure you that it is
+the solemn truth."
+
+"Go ahead, Miss Lanahan," said the detective. "I am prepared to believe
+whatever you may say."
+
+The girl sat down, at Mrs. Stapleton's request. She still was somewhat
+weak, from her recent illness.
+
+"It was a week ago last Wednesday. I left the house with Master Jack at
+half-past ten, and we drove to the Bois."
+
+"Just a moment, please." Duvall stopped her with a quick gesture. "How
+long had you been going to the Bois in this way?"
+
+"Over six weeks."
+
+"And you always left about the same time--half-past ten?"
+
+"Always."
+
+"Who accompanied you besides the child?"
+
+"Francois--the chauffeur."
+
+"Always?"
+
+"Yes."
+
+Duvall turned to Mrs. Stapleton. "How long has this man Francois been in
+your employ?"
+
+"A year--in June."
+
+"You have found him honest, reliable?"
+
+"Always. Otherwise I should not have kept him."
+
+The detective turned to Mary Lanahan. "Go ahead, please," he said.
+
+"We reached the Bois shortly before eleven--Francois had orders to go
+slowly, when Master Jack was in the machine--and drove about for fifteen
+minutes. Then we stopped at the place where we were in the habit of
+playing."
+
+"Was it always the same place?"
+
+"Yes. There is a smooth field of grass there, and a clump of trees by
+the road, where the machine always waited."
+
+"Go on."
+
+"We left the car, and walked out over the grass. Master Jack had a big
+rubber ball, and he was kicking it along, and running after it.
+Sometimes he would kick it to me, and I would throw it back to him. We
+played about in that way for over half an hour. Mrs. Stapleton wished
+the boy to have the exercise."
+
+"I see. And you generally played about in the same place?"
+
+"Yes."
+
+"How far from the road?"
+
+"About three hundred feet."
+
+"And from the nearest bushes, or woods?"
+
+"A little more than that, I should say."
+
+"You could see Francois, in the machine, from where you were?"
+
+"Yes, I could see the machine. I could not always see Francois; for
+sometimes he would get out, and walk about, or sit under the trees and
+smoke a cigarette."
+
+"Do you remember noticing him, on this particular morning?"
+
+"Yes. I saw him sitting in the machine."
+
+"What was he doing?"
+
+"Reading a newspaper."
+
+"Had he ever done that before?"
+
+The girl hesitated, as though a new idea had come to her. "No--I cannot
+remember that he ever had."
+
+"Very well. Go ahead with your story."
+
+"Well--after we had played for about half an hour--I got tired and sat
+down on the grass. Master Jack still kept playing about with the ball. I
+sat idly, looking at the sky, the road--dreaming--"
+
+"About what?" interrupted the detective, suddenly.
+
+The girl colored. "About--about some people I know."
+
+"Go ahead."
+
+"I heard the boy playing, behind me. Then I looked around--and--he was
+gone!" The nurse made this statement in a voice so full of awe that it
+carried conviction to her hearers. Duvall felt that, whatever the real
+facts of the disappearance of the child, this woman's story was true.
+
+"What did you do then?"
+
+"I stood up and looked about. I thought Master Jack was hiding from
+me--playing a joke on me. Then I realized that there was no place that
+he could hide. The nearest trees were too far off. He could not have
+reached them. I called and called. I was very much frightened."
+
+"Francois, who heard me, came running over the grass. I asked him if he
+had seen Master Jack. He said, no, that he had not seen anyone. After
+that we searched everywhere--in the woods, along the road--for nearly an
+hour, but could find nothing. Then we came home, and told Mrs.
+Stapleton." The girl looked at her employers in fright.
+
+"What about the rubber ball?" Duvall asked, suddenly.
+
+"It--it was gone."
+
+"Then it is clear that the child must have been taken away peaceably,
+without objection on his part. Had he struggled, cried, he would have
+dropped the ball, would he not?"
+
+"I suppose so."
+
+"How long was your head turned from him--while you were--dreaming?"
+
+"About a minute."
+
+"Not more?"
+
+"No."
+
+"How do you estimate the time so closely?"
+
+"I'm sure it could not have been longer. A minute is quite a long
+time."
+
+"What time was it when you got back to the house?"
+
+"About--about one o'clock, I think." The girl turned to Mrs. Stapleton
+for confirmation of her answer.
+
+"It was a quarter-past one," said Mrs. Stapleton, promptly. "I noted the
+time particularly, because it was later than usual. Mary had orders to
+bring Jack back for luncheon not later than one."
+
+Duvall began to make some figures on a piece of paper. "You fix the time
+of the boy's disappearance at 11.30. You say you hunted for him an hour.
+That would be 12.30." He looked at the girl searchingly. "You arrived
+home at 1.15. That would mean that it took 45 minutes to get here." He
+turned to Stapleton. "Please send for your chauffeur, Francois."
+
+Mr. Stapleton rang a bell, and ordered the servant who responded to send
+in the chauffeur. Meanwhile Mary Lanahan was regarding Duvall with
+nervous apprehension.
+
+"We must have hunted for him longer than I thought," she said, at
+length.
+
+Duvall made no reply, but waited until the arrival of the chauffeur. He
+proved to be a short, heavily built man, with long powerful arms, and a
+swarthy face--evidently from the south of France. His countenance was
+stolid and emotionless. He appeared the well trained servant.
+
+Duvall addressed him at once. "How long would it take you, my man,
+driving fast, to reach this house from the spot in the Bois where Master
+Jack was lost?"
+
+The man responded at once. "Ten minutes," he said, "easily."
+
+"What time was it when this woman," the detective indicated the nurse,
+"called to you, on discovering that the child was gone?"
+
+"I do not know."
+
+"Have you no idea?"
+
+"It must have been about twelve o'clock. We hunted for the boy till
+about one--then came home."
+
+"The nurse says it was half-past eleven."
+
+The man shrugged his shoulders. "It may have been. I did not observe the
+time."
+
+"What were you doing?"
+
+"I was asleep."
+
+Mr. Stapleton started. "Asleep?" he demanded, angrily.
+
+The man nodded. "The day was warm. I had nothing to do. For a time I
+read the paper. I must have dozed in my seat; for, the next thing I
+knew, the nurse was calling to me, and the boy was gone."
+
+Duvall frowned. "Then you could not say whether anyone else was near the
+nurse and the boy, at the time he was kidnapped?"
+
+"No, monsieur. I could not."
+
+"That will do." The detective turned to Mr. Stapleton. "Have your man
+drive us to the place where all this occurred."
+
+The banker gave the man the order, and he left the room. Then Duvall
+turned again to Mary Lanahan.
+
+"You were taken suddenly ill one day last week. Tell us about it."
+
+The woman looked up. "It was very mysterious, sir. I went out for a
+walk. At a cafe in the Rue St. Honore I had a cup of chocolate."
+
+"Alone?" asked the detective, sharply.
+
+The woman colored. "No," she faltered. "I--I was with a friend."
+
+"Who?"
+
+"A--a gentleman I know." She glanced fearfully at Mr. Stapleton. "I--I
+would rather not give his name."
+
+"Was it Alphonse Valentin?" asked Duvall, quickly.
+
+The woman colored still more deeply. "Yes," she replied, in scarcely
+audible tones.
+
+The banker regarded her in surprise. "Alphonse Valentin!" he cried. "The
+fellow I discharged last year, for dishonesty? Mr. Duvall--he's your
+man!"
+
+"No--no!" exclaimed the nurse, excitedly. "He knows nothing of the
+matter--nothing!"
+
+"That remains to be seen," remarked Duvall, slowly. "Where did you meet
+this fellow, Valentin?"
+
+"At the cafe in the Rue St. Honore."
+
+"You had met him there frequently before?"
+
+"Yes."
+
+"After you left the cafe, what did you do?"
+
+"We walked to the Champs Elysees and sat on a bench, talking. Suddenly I
+felt very ill. Mr. Valentin called a cab and sent me home."
+
+"Give me the address of this cafe, please."
+
+The woman did so. As Duvall was entering it in his notebook, a servant
+announced that the automobile was at the door.
+
+In fifteen minutes the party, consisting of Mr. Stapleton, Duvall, and
+Mary Lanahan, were leaving the car at the spot in the Bois de Boulogne
+which had been the scene of the kidnapping. Francois was ordered to
+drive his machine to the exact spot, as nearly as he could tell, that it
+had occupied on the previous occasion. Mary Lanahan led the others to
+the place on the grass where she had sat.
+
+It was evident at once that the distances she had named in telling her
+story were less, if anything, than the actual facts. It was quite
+impossible to see how, in any way, the child could have been taken from
+the spot she indicated, to the woods, without consuming a considerable
+period of time--five minutes, at least. To believe that the nurse could
+have turned away her head for a moment, and then looked around to find
+the boy gone seemed the sheerest fabric of the imagination; yet the
+woman, in repeating her story, stuck to it with a grim pertinacity
+which, it seemed, could come only from the knowledge that she was
+telling the truth.
+
+Ten days had elapsed since the boy had been kidnapped. It seemed almost
+useless to search the spot for any evidences of the crime. Yet Duvall
+began to go over the ground where the nurse testified that she had sat,
+with the most minute care. Inch by inch, he examined the turf,
+subjecting almost every blade of grass to a separate examination. The
+operation required over half an hour, and both Mr. Stapleton and the
+nurse grew tired of watching him, and strolled about aimlessly.
+
+Hence they did not see him pick up a tiny object from the grass. It was
+a half-smoked cigarette, dirty and almost falling to pieces from the
+action of the weather, yet held together by a slender tip of gold.
+
+He placed it carefully within his pocketbook, and rose. "Nothing more to
+be done here," he called to Mr. Stapleton, and in a moment the three
+were proceeding toward the waiting automobile.
+
+Upon the return to the house, Mr. Stapleton drew the detective into his
+library. "Have you discovered anything, Mr. Duvall?" he inquired, making
+an effort to conceal his almost frantic anxiety.
+
+"I do not know--yet. I may have a clue; but I am not sure."
+
+"What do you think of the woman's story?"
+
+"It seems impossible to believe it."
+
+"You think, then, that she had a hand in the matter--she and this fellow
+Valentin?"
+
+"It begins to look like it."
+
+"On what do you base your conclusions, Mr. Duvall? I cannot bring myself
+to believe that Mary Lanahan is lying, ready as I am to suspect this
+fellow Valentin."
+
+"First, Mr. Stapleton, on the facts themselves. The boy could not have
+been taken away without her knowledge. Secondly, upon some minor
+matters--her error of half an hour, in telling her story, for instance."
+
+"I am sorry, Mr. Duvall, but I cannot believe that you are right. I'd
+suspect Valentin, at once; but if Mary Lanahan is not telling the truth,
+then my experience of twenty years in judging human nature has been
+wasted."
+
+"Yet you yourself heard her admit that she was with Valentin only last
+Friday, the day she was taken ill."
+
+"Yes. That is true." Mr. Stapleton passed his hand uncertainly across
+his forehead. "It's too much for me."
+
+"Let me have a word with the nurse, alone, before I go," asked Duvall.
+
+"Certainly," replied the banker. "I'll send her in to you."
+
+When Mary Lanahan entered the room, the detective went up to her and
+eyed her sternly. "Was Alphonse Valentin with you at any time, in the
+Bois, that day?"
+
+"No," replied the girl, steadily.
+
+"Does he smoke gold-tipped cigarettes?" asked Duvall, suddenly.
+
+The effect of this question upon the nurse was startling. She recoiled
+as though the detective had struck her. "He--he does not smoke at all,"
+she gasped, her face gray with fear.
+
+"Don't lie to me!"
+
+"He does not smoke at all," repeated the girl, almost mechanically, and
+stood confronting him with a defiant air.
+
+"Very well. That is all." The detective turned from the room and left
+the house.
+
+He did not, however, go very far. It was rapidly becoming dark. He
+passed down the street until he judged he was out of sight of the house,
+then slowly retraced his steps upon the other side, until he had reached
+a point nearly opposite the small iron gateway which served as the
+servants' entrance to Mr. Stapleton's house. Here, hidden behind a
+tree, he watched for perhaps half an hour.
+
+At the expiration of this period, he was rewarded by seeing a young man,
+evidently an under servant, emerge from the gateway. Duvall watched him
+as he proceeded down the street, then began to follow him.
+
+The young man seemed in no great hurry, and at the junction of the
+avenue with the Champs Elysees, Duvall accosted him, speaking in French.
+
+"Do you want to earn twenty francs, my friend?" he asked pleasantly.
+
+The boy regarded him with a quizzical smile. "Who does not, Monsieur?"
+he replied.
+
+"Let me see the note you have in your hand."
+
+The boy drew back suddenly, and made as though to thrust the letter into
+his pocket. "It is impossible, Monsieur," he began.
+
+Duvall took out a gold twenty-franc piece. "I intend to have the letter,
+my man. If you will give it to me peaceably, here are the twenty francs;
+if not, I shall be obliged to take it from you by force."
+
+The boy regarded the detective for a moment, as though contemplating
+flight. Duvall seized him by the collar. "Give me the note," he cried,
+"or I'll call a gendarme and have you placed under arrest!"
+
+The boy allowed the letter to drop to the pavement, seized the
+twenty-franc piece, and took to his heels.
+
+Duvall picked it up. As he had expected, it was addressed to Alphonse
+Valentin, ---- Boulevard St. Michel. He had waited, on the chance that
+Mary Lanahan would lose no time in warning her probable confederate.
+
+The letter gave him the man's address. That was so much accomplished, at
+least. Then he tore it open, and read the contents. They proved more
+mystifying than anything that he had yet encountered in this mysterious
+affair.
+
+"Destroy the cigarettes!" These three words comprised the entire
+contents of the note.
+
+
+
+
+CHAPTER VI
+
+
+Alphonse Valentin came up to Grace and took her roughly by the arm.
+"Come with me," he said, and started up the street.
+
+At first she felt inclined to resist him. A signal to a passing
+gendarme, and she could have had the man placed under arrest. Monsieur
+Lefevre had taken care to provide her with credentials that would insure
+her obtaining instant assistance from any member of the police.
+
+Then another thought came to her. This man Valentin she very much
+desired to see. His position, clinging to the rear of the automobile,
+indicated that he was in all probability not a confederate of the
+kidnappers. Just what he was, she could not imagine. She determined to
+go along with him, and hear what he had to say.
+
+A few minutes' walk brought them to the man's lodgings. For some
+reason, which she did not understand, the automobile in which she had
+been a prisoner had stopped on the Boulevard St. Michel within a short
+distance of Valentin's rooms.
+
+When they reached the house, Valentin, instead of opening the door with
+a key, rang the bell. The woman who had previously admitted Grace came
+to the door. Valentin nodded.
+
+"Is this the woman?" he asked.
+
+"Yes," said the landlady, recognizing her at once. "This is the one."
+
+"Good!" Valentin closed the door and led the way to his room. Grace
+followed, wondering what the man intended to do.
+
+"Why have you come here twice during the past two days?" he asked,
+abruptly, after he had lit the lamp and carefully shut the door.
+
+Grace determined to be quite frank with him. "I wanted to ask you some
+questions, Monsieur Valentin," she replied.
+
+"Ha! You know my name?"
+
+"Certainly."
+
+He appeared somewhat uneasy. "What are you up to?"
+
+"I am trying to find Mr. Stapleton's child."
+
+A queer smile came over the fellow's face. "Is that why you stole the
+cigarettes?" he asked.
+
+"I did not steal them. They were taken by a man with a black beard, who
+came in through the window when I was here."
+
+"A black beard?" He smiled incredulously. "And you let him take them."
+
+"Yes. Why not? Were they of such great value?"
+
+He glanced about uneasily, but did not reply to her question. "Who was
+the man?" he presently asked.
+
+"I do not know. I followed him. He entered Mr. Stapleton's house."
+
+"Sacre! It must have been Francois!"
+
+"Hardly. Francois has no beard."
+
+"But he might have been disguised." He seemed very much perturbed. "What
+a pity I was so careless!"
+
+"Monsieur Valentin, will you please tell me what those cigarettes have
+to do with the kidnapping of Mr. Stapleton's child?"
+
+He looked at her closely for a moment. "Everything," he answered
+gloomily, "and--nothing. I was a fool to have left them here."
+
+Grace began to feel more and more composed. This man did not talk like
+one of the band of criminals. "Do you know where the child is?" she
+suddenly asked.
+
+"Perhaps." He observed her narrowly. "Do you?"
+
+"No. If I did, I should restore him to his poor mother."
+
+"What were you doing in that automobile?"
+
+"I was a prisoner. And you?"
+
+Again he evaded her question. "It is my own affair," he growled.
+
+"Did you not see who it was that drove the car?" she asked.
+
+Instead of replying, he flung himself into a chair. "Sit down,
+Mademoiselle, and tell me the whole story. If I find that you are frank
+with me, I promise to be equally so with you."
+
+Suddenly Grace felt an intuition that the man was honest. She determined
+to do as he asked. "Very well. I will tell you the truth. I am trying to
+recover Mr. Stapleton's child. Last night I was watching the house. I
+was seized from behind, thrown into an automobile, and taken--I do not
+know where. This morning a message to Mr. Stapleton was given me.
+Tonight I was brought here, blindfolded, in an automobile. Then I met
+you. That is all I know."
+
+Valentin appeared disappointed. "Then you do not know where the child
+is?" he asked.
+
+"The child is where I was--I saw it."
+
+As Grace said this, her companion leaped excitedly from his chair. "Then
+we have them!" he cried.
+
+"I do not understand."
+
+"Mademoiselle, this evening I was watching Monsieur Stapleton's house.
+Like yourself, I desire to recover the child. I saw Francois leave in
+Monsieur Stapleton's automobile. I climbed in behind, as he left the
+house. It was dark. He did not see me. He drove out toward Versailles."
+
+"Toward Versailles?" exclaimed Grace.
+
+"Yes. Why do you seem so surprised."
+
+"Never mind. Go on."
+
+"After a time, he stopped by the roadside. I got out, and hid in the
+shadow of some trees. Presently you were brought, blindfolded, by a man,
+who entered the car with you. When it again started, I climbed on
+behind. That is how I came to meet you."
+
+"Then you don't know where the house is, from which I was brought?"
+
+"No. There are many houses--all about. There was no way of knowing, in
+the dark. Did you come far--when they brought you to the automobile?"
+
+"Yes. Several hundred yards, at least. But you know the spot, on the
+roadside?"
+
+"Yes. I can find it, without difficulty."
+
+"Monsieur Valentin, I have a plan--a very dangerous plan--for recovering
+Mr. Stapleton's boy. I cannot tell you what it is now. Tomorrow I will
+tell you--tomorrow afternoon. I shall want your assistance."
+
+"What am I to do?"
+
+"Can you drive an automobile?"
+
+The man smiled. "Decidedly. It is my profession."
+
+"Splendid! You will wait for me here, and I will come, and tell you what
+you are to do. I shall arrive not later than six o'clock." She rose.
+"Now I must go; but before I do so, tell me one thing. What is the
+mystery of the gold-tipped cigarettes?"
+
+Her question seemed to drive from Valentin's face all the good nature
+that had dwelt there the moment before. "I cannot tell you that," he
+growled. "You must not ask me. Let me advise you to drop the matter of
+the cigarettes, and report your message to Mr. Stapleton at once."
+
+For a moment, Grace almost regretted her frankness. Suppose, after all,
+he should prove to be but a confederate of the kidnappers, in league
+with Mary Lanahan, the nurse, to spirit the boy away in the first place,
+and now sent by them, in the guise of a spy clinging to the rear of the
+automobile, to find out what step she proposed to take to capture them?
+She paused in indecision. Suddenly there was a tapping upon the door of
+the room.
+
+Valentin went to the door and cautiously opened it. The landlady stood
+on the landing outside. "There is a man to see you, at the door below,
+Monsieur," she said in a low tone.
+
+"Who is it?"
+
+"I do not know. He gives the name of Victor Girard."
+
+"Very well. Send him up."
+
+Grace heard the name--Victor Girard. A sudden wave of weakness swept
+over her. It was Richard! He had used the name frequently, in the past.
+She heard him ascending the short flight of stairs. There was no escape.
+Yet Monsieur Lefevre particularly insisted that he should not recognize
+her. She hastily drew down her veil. "Get rid of him as soon as you
+can," she whispered to Valentin, and shrunk back into the shadow.
+
+Duvall came in, glancing sharply about him. He had been waiting to see
+Valentin since early in the evening, and had inquired for him twice
+before, only to find that he was out.
+
+"What can I do for you, Monsieur?" inquired Valentin.
+
+The detective drew the note from his pocket--the note which Mary Lanahan
+had sent to Valentin, and which Duvall had intercepted. "This is for
+you, Monsieur?" he asked, then suddenly paused, astounded. In the dim
+light, he caught sight of Grace, standing on the opposite side of the
+room, watching him closely. "I--I thought--Monsieur--I thought you were
+alone," he gasped, his eyes fixed on Grace as though he had seen a
+ghost. "I--I beg your pardon, but--" He was unable to proceed.
+
+Valentin looked at him in amazement. "What is it, my friend?" he asked
+sharply. "Tell me your business, if you please, and go. I have a
+visitor."
+
+"Yes--Monsieur--so--so I see." Duvall pulled himself together with a
+mighty effort and turned his glance to Valentin. He had suffered a great
+shock. For a moment he would have been ready to swear that Grace, his
+dear wife, stood before him in the flesh--and yet the thing was an
+absurdity: Grace, with her golden brown hair, her clear complexion, was
+three thousand miles away! This woman, dark, typically French, was quite
+evidently an entirely different person; yet the resemblance was
+startling--he felt himself shaking in every fiber.
+
+"Well, Monsieur, give me the letter, since you say it is for me," he
+heard Valentin saying.
+
+In an instant he had recovered his self possession. "Here," he
+exclaimed, handing the note to the man before him. "It is from Mary
+Lanahan. I have read it."
+
+"You have read it, Monsieur!" Valentin exclaimed, angrily. "By what
+right, then, do you presume to read my letters?" He took the note and
+hurriedly read its contents. "Sacre!" he exclaimed. "What does this
+mean?"
+
+"It means, my friend, that I want that box of gold-tipped cigarettes."
+
+Grace started. So Richard, too, was interested in the recovery of these
+mysterious cigarettes. What on earth, she wondered, could it mean?
+
+"In the first place, Monsieur, let me inform you that I have no
+cigarettes, gold-tipped or otherwise. In the second place, I question
+your right to make any such demands."
+
+"Does not the note from Mary Lanahan request you to destroy them?"
+
+Valentin turned pale. "I tell you I have no such cigarettes!" he cried.
+
+"Are they not the sort, then, that you usually smoke?"
+
+"I do not smoke at all, Monsieur."
+
+Duvall laughed. "So you both tell the same story, it seems. My friend, I
+dislike to discuss these matters before a stranger." He glanced
+significantly at Grace.
+
+She dared not go. To speak--even to bid Valentin good evening, would,
+she felt sure, betray her. So she remained silent.
+
+"Then take yourself off. I certainly have no desire to discuss them. I
+tell you, I do not smoke--I have no cigarettes--that is enough!"
+
+"What does that note mean, then?" asked Duvall sternly.
+
+"That is Miss Lanahan's affair--and mine."
+
+Duvall drew out his pocketbook, and extracted from it the bit of
+cigarette stump, with the gold tip, which he had found that morning in
+the Bois de Boulogne. "Monsieur Valentin," he said, "I found this end of
+a cigarette at the exact place in the grass, in the Bois de Boulogne,
+where Mr. Stapleton's child and nurse were, when the boy was stolen. The
+chauffeur was asleep. You could readily have walked up, taken away the
+child, and no one would have been the wiser. The story of Mary Lanahan,
+that no one came near her, that the boy disappeared into thin air, is
+absurd. The presence of the half-smoked cigarette, of a kind which I
+have reason to believe you use, convinces me that you were there in the
+Bois, with the nurse, at the time of the kidnapping--if indeed you did
+not take an active part in it. The message from Mary Lanahan, which I
+have just handed you, directing you to destroy the cigarettes,--which,
+no doubt, she feared, after my questioning, might be used as evidence
+against you,--serves as strong additional proof. I believe that you know
+where Mr. Stapleton's child is."
+
+The statements which her husband made convinced Grace that she had made
+a mistake in confiding in Valentin. She herself had seen the
+gold-tipped cigarettes on his table--had seen them stolen. It was not
+very conclusive evidence, she realized; but, taken with the nurse's
+letter, it was significant.
+
+Valentin, however, did not appear to be greatly alarmed by the
+detective's charges. "You are mistaken, Monsieur," he said quietly. "I
+know nothing about the affair."
+
+"Then what does this note mean?"
+
+"That I cannot tell you. And, if you have any other questions to ask, I
+beg that you will come again--at another time. I, as you see, am engaged
+for the moment." He indicated Grace with a glance.
+
+Duvall looked about, then turned to the door. His object in coming had
+been fulfilled. He had seen Valentin--located him--he hoped frightened
+him. It was one of his theories that a man, frightened by the knowledge
+that he is being closely pursued, is far more likely to make a false
+step, than one who fancies himself secure.
+
+He darted a curious glance at Grace, as he left the room; but her face,
+concealed in the shadow, told him nothing. Her silent presence filled
+him with strange disquietude. He stationed himself outside the doorway
+of the house, determined to learn, if possible, who she was, by
+following her, when she left the place. He had not counted on Valentin's
+being with her.
+
+The two left the house together, and the man at once called a cab. Into
+this he put Grace, all the while eying Duvall savagely. The latter gave
+up all ideas of pursuing Grace, and returned, somewhat disgruntled, to
+his hotel. He had barely reached it, when a message was brought to him,
+summoning him to Mr. Stapleton's house.
+
+Grace, meanwhile, had driven at once to the banker's, and delivered to
+him the message with which she had been intrusted by the man in the
+black mask that morning.
+
+Mr. Stapleton's face grew more and more angry as she proceeded with her
+story. He jumped up, as soon as he learned the purport of it, and,
+ringing up Duvall's hotel, requested the detective to come to him at
+once. Then he turned to Grace.
+
+"You have no idea where this place is located?"
+
+"Not the slightest."
+
+"You say you saw my boy? He was safe?"
+
+"I saw a child, which I was told was yours, Mr. Stapleton. I did not
+recognize him, of course. You know I have never seen your son. Also, he
+was dressed as a girl."
+
+Mr. Stapleton produced a photograph with nervous haste. "Was he like
+this?" he demanded.
+
+"Yes. It was the same." There was sufficient resemblance, even in the
+disguise the boy wore, for Grace to be practically certain of his
+identity.
+
+"How am I to know that these scoundrels will keep their word?" Mr.
+Stapleton groaned, his head on his hands.
+
+"Do you intend, then, to give them the money?"
+
+"Certainly. Do you suppose I would take any chances, for the matter of a
+hundred thousand dollars--or twice as much, for that matter? His mother
+and I are unable to sleep, to eat, to do anything in fact, under the
+strain of this thing. I shall by all means do as they ask."
+
+"But they will get away."
+
+"That is nothing to me. Let them. Once my boy is safe, I can spend
+another hundred thousand to catch them; but not now--when one false step
+might mean his death."
+
+"They won't harm him, Mr. Stapleton. They are too anxious for the
+money, to let anything happen to him."
+
+"I'll take no chances."
+
+Grace rose. "Then I might as well be going," she said. "I don't see that
+I can do anything more. I shall report the matter to the Prefect of
+Police at once."
+
+"Very well. And be good enough to say to him that I particularly desire
+that no steps be taken to prevent the carrying out of the plan. I shall
+pay this money and regain my boy. After that, the police may do as they
+like. Good evening."
+
+"Good evening." Grace left the house, feeling singularly disappointed,
+in spite of the fact that Mr. Stapleton's decision apparently meant that
+Richard's work in Paris, as well as her own, was likely to be brought to
+a sudden termination.
+
+As she was leaving the house, she saw Richard drive up in a cab. The
+sight of him filled her with joy; although she was forced to conceal it,
+and pass him by with a look of indifference. In the darkness, she knew
+she was safe. He recognized her of course,--recognized her, that is, as
+the woman he had seen in Valentin's room,--and her presence here at Mr.
+Stapleton's house evidently filled him with surprise. For a moment, she
+thought he was about to speak to her, as he descended from his cab; but
+she turned away and hurried down the street, and when she looked back,
+he had entered the house.
+
+
+
+
+CHAPTER VII
+
+
+Mr. Stapleton was standing in the middle of the library, when Duvall
+entered. He turned to him excitedly.
+
+"Mr. Duvall," he said, "I have just heard news that I hope will restore
+my boy to me within the next twenty-four hours!"
+
+"From the woman who just left the house?"
+
+"Yes."
+
+"Who is she?"
+
+"An agent of the police."
+
+"Ah! Are you certain of that?"
+
+"I know only what she says."
+
+Duvall looked at him curiously. "What is the news she has brought you?"
+
+"A message from the scoundrels who have stolen the child. They want a
+hundred thousand dollars, to return him."
+
+"And she brought you that message?"
+
+"Yes." The banker regarded his questioner uneasily.
+
+"Does it not seem rather singular, Mr. Stapleton, that a member of the
+Paris police should come to you with a message from the kidnappers?"
+
+Mr. Stapleton frowned. "I had not considered that aspect of the case,
+Mr. Duvall. I was--and am--too anxious to get my boy back, to care by
+whom these fellows deliver their terms."
+
+"What was the message, Mr. Stapleton?"
+
+"I am to drive along the road to Versailles tomorrow evening, leaving
+here at eight o'clock, and moving at the rate of twelve miles an hour.
+Somewhere on that road, an automobile in passing will signal me with a
+blue light. I am then to slow up and toss into the other machine a
+package containing one hundred thousand dollars. If I do this, and make
+no attempt to follow or capture the rascals, they agree to deliver the
+child here--at my house--by the time I return home."
+
+Duvall listened to Mr. Stapleton's words with growing interest. "They
+are a shrewd lot," he exclaimed. "They will get away in their machine,
+and have ample opportunity to examine the package to see that it
+contains the amount they demand. By signaling to confederates at any
+point along the road, or in another automobile, they can advise them
+whether or not to return the child."
+
+"But how will they be able to do this, without running the risk of being
+caught?"
+
+"That is easy. They take the boy to Paris, employ a passerby--a man of
+their own class, no doubt--for a few francs, to deliver him at your
+door. To trace them, through that means, will be impossible. If you give
+them the money, the chances are that they will never be caught."
+
+"Nevertheless, I shall give it to them."
+
+"I expected that, Mr. Stapleton. I can understand your feelings. It is
+not right, of course, to submit to this blackmail; but no doubt, were I
+situated as you are, I would do the same thing. Still, it is a great
+pity."
+
+"Why?"
+
+"Because we have an excellent chance to capture these fellows."
+
+"And lose the boy!"
+
+"Yes, that might be true. Such men are apt to retaliate very promptly,
+and very severely. They have no pity. I wish I might handle the case to
+suit myself."
+
+"What would you do?"
+
+"I would arrange to follow you, in a fast car, keeping say five hundred
+feet in the rear. I should have several men, well armed, in the car. By
+watching carefully, with field glasses if necessary, I would observe the
+car which signaled you with the blue light. When this car passed me, I
+would follow, but make no move which would alarm the kidnappers until
+they had given the signal--whatever it is--that would ensure your boy
+being returned to you. Then I would close in on them, and arrest them."
+
+"Your plan, Mr. Duvall, is open to serious objections. Suppose these
+men, undoubtedly on the watch, observe that they are being followed.
+They will give no signal--and I will lose not only my child, but the one
+hundred thousand dollars as well. No, no, I want no interference in the
+matter whatever."
+
+Duvall remained a moment in silence. "Very well, Mr. Stapleton, I am
+under your orders, of course. But I dislike very much to see these
+fellows get away."
+
+"So do I; but there's no help for it."
+
+"If I can work out a plan for their capture, which will not involve the
+loss of the boy, you are willing, I take it, to let me go ahead?"
+
+"Yes; but I insist that you first submit the plan to me."
+
+"Very well. And now, another matter. This woman who brought the message
+to you is, you say, an agent of the police. Did she attempt to explain
+how she came by the message?"
+
+"Yes. She was forcibly abducted, last night, carried a long distance out
+into the country, and the instructions given her. She was brought back
+to Paris, blindfolded, tonight."
+
+"Mr. Stapleton, what would you say were I to tell you that less than an
+hour ago I saw this woman in the rooms of Alphonse Valentin, a man whom
+I suspect to be very deeply concerned in the kidnapping of your son?"
+
+Stapleton started. "Is it possible?" he said. "Have you any idea what
+she was doing there?"
+
+"No. They seemed on excellent terms, however. Of course, it is not
+impossible that an agent of the police might pose as a friend of one of
+the criminals, and thus obtain information. But it looks decidedly
+queer."
+
+"It does, indeed. Still, as I said before, if I get my boy back, I shall
+be satisfied." He took a turn about the room, chewing nervously upon
+his long black cigar. "Now, Mr. Duvall, what is your plan to capture
+these fellows?"
+
+Duvall sat in deep thought for sometime. "It is not an easy matter, Mr.
+Stapleton, but there is one way which promises success, and that, too,
+without interfering with your arrangements to recover your boy."
+
+"What is it?"
+
+"This. It is necessary for us, in some way, to identify the car which
+gives you the signal of the blue light. It will pass close to you, at a
+moderate speed. I want you to mark that car, so that it may be
+recognized at once."
+
+"How can I do that?"
+
+"I will place in the bottom of your machine a small device, consisting
+of a rubber bulb, equipped with a small nozzle, projecting through a
+hole in the body of the car. The bulb will be filled with indelible red
+stain. When you stand up, to toss the package of money to the
+kidnappers, you must press this bulb with your foot. The two cars will
+then be side by side. The pressure on the bulb will discharge a blast of
+the red stain against the body and wheels of the car opposite you. It
+will then be a simple matter to identify it."
+
+"Yes--yes. I see that. But what then?"
+
+"The car, in passing you, will be headed for Paris. Undoubtedly it is
+the intention of these fellows to enter the city. I shall station myself
+at the Porte de Versailles, and I will arrange to have other men,
+members of the detective bureau, stationed at the neighboring gates in
+the fortifications. All cars entering the city will be momentarily
+halted. The one which bears upon its body or wheels the red stain will
+be seized, its occupants arrested."
+
+"But suppose they have not yet notified their confederates to return the
+boy to me?"
+
+"In that event, I feel certain that the child will be found in the
+automobile with them. Look at the thing as you would, were you in their
+place. They are forced to act with great quickness. Were they to signal,
+by lights or otherwise, to persons along the road, they could hardly
+hope to get the boy to your house before you yourself return there. They
+know you will return home immediately at your best speed as soon as you
+have delivered the money to them. What more likely, then, that they will
+have the boy with them in the car, will drive to some prearranged point
+in Paris, and deliver him to the person who will bring him to your
+house? That would seem, to my mind, their most probable plan."
+
+"And if not--if the child is not with them?"
+
+"Then there are but two courses open to them. The first is to signal, by
+lights or otherwise, to their confederates, before they enter Paris. If
+they do this, the boy will be returned to you, and we will capture the
+men as well. The only other alternative, of course, is for them to
+notify their confederates after they enter Paris."
+
+"But, if you arrest him at the barrier, they cannot do that, and my boy
+will not be sent back."
+
+"That is true; but I do not think they will wait to notify their
+confederates until after they enter Paris."
+
+"Why not, Mr. Duvall?"
+
+"First, because of the danger of being observed, in the crowded streets
+of the city. Secondly, because I do not think the child is in Paris at
+all. The woman who brought you the message from the kidnappers, I
+understand, saw the child at a point some distance in the country. It
+seems unlikely that these men would run the risk of conveying the child
+into the city, in broad daylight. By having the boy with them in the
+car, they avoid all danger of signaling anybody. They merely inspect the
+package of money, run into Paris, fully believing themselves for the
+time being safe, drop the child at a convenient point, divide the
+plunder, and scatter to their respective hiding places. Criminals of
+this sort know perfectly well that they are far safer, hiding in a big
+city, than fleeing through the country in an automobile. I feel scarcely
+any doubt that they have the child with them."
+
+"But if he is still in the country, and they wait until after they are
+in Paris before notifying their confederates?"
+
+"Then the latter are obliged to journey a long distance out into the
+country, get the child, and bring him back to your house. That would
+require a considerable period. They could not possibly do it before you
+return home."
+
+Mr. Stapleton considered the matter for a long time in silence. "Your
+arguments seem sound, Mr. Duvall," he presently observed. "Like
+yourself, I am anxious to capture these fellows. It makes my blood boil,
+to think of their getting away. Of course, your deductions may be
+wrong."
+
+"Then at least we will get the perpetrators of the crime, and it is most
+likely that one of them, at least, may be persuaded to turn state's
+evidence, and disclose the whereabouts of your son."
+
+Mr. Stapleton pondered the matter with great care. Evidently he feared
+any course of action which did not insure the return of the child.
+
+"It seems to me, Mr. Stapleton," the detective went on, "that you owe it
+to the public to let me make this effort to capture these fellows. It is
+a grave danger to the community, to have such rogues at large. Let me
+try my plan. Even if it fails, you are no worse off than you are now.
+The attempt cannot in any way be traced to you."
+
+"Very well," said the banker, nervously. "It is a chance--that's all.
+However, since it seems to involve no breach of faith on my part, I am
+willing to take it."
+
+"Good! I will bring the device I spoke of to your house tomorrow, and
+attach it to your car. Your man Francois will drive you, I presume."
+
+"Yes."
+
+"You trust him?"
+
+"I have no reasons for not doing so. And besides he will know nothing of
+the affair. His part will be merely to drive the car, as I direct him."
+
+Duvall thought for a moment. "You will not, of course, give him his
+instructions until the last moment--just before you start."
+
+"No. That will be best, I think."
+
+"Undoubtedly. And to avoid any possible interference, I think I had
+better not attach the identifying device of which I have spoken to your
+car until late tomorrow afternoon, immediately before you set out. Then,
+if by any chance your chauffeur is in this plot, he will have no
+opportunity to give a warning."
+
+"Very well. I think, however, that your precautions are needless. There
+has been nothing whatever brought out to connect Francois with this
+matter."
+
+"I know; but it is well to be careful. You will leave here tomorrow
+evening, at eight o'clock?"
+
+"Yes. Promptly at eight."
+
+"You might do well to have someone with you, some member of the police,
+perhaps."
+
+"The instructions expressly forbid it."
+
+"Ah--I see. These fellows are shrewd." He took up his hat. "Until
+tomorrow then. Good night."
+
+"Good night."
+
+
+
+
+CHAPTER VIII
+
+
+At the same hour that Richard Duvall was arranging with Mr. Stapleton
+his plan for the capture of the kidnappers the following day, Grace was
+closeted with Monsieur Lefevre, the Prefect of Police, in the latter's
+library, going over the affair in all its details. The Prefect was
+speaking, ticking off on his fingers the points in the case as he
+proceeded.
+
+"First, we have the impossible story of the nurse, Mary Lanahan. She
+seems to be telling the truth; yet I believe she is lying. In my
+opinion, she is deeply concerned in the whole matter."
+
+"But what about the attempt to poison her?"
+
+"It is highly probable that she poisoned herself, taking a slight dose
+only. This would divert suspicion from her."
+
+"I see."
+
+"Then we have the case of Alphonse Valentin, and the mysterious
+gold-tipped cigarettes. Your husband, Monsieur Duvall, I am informed,
+has found one of these cigarettes, partly smoked, on the grass at the
+scene of the crime. This might indicate that Valentin was there, with
+her, on some occasion, but not necessarily on the day the kidnapping
+occurred. It might readily have been the day before--or the week before,
+for that matter."
+
+"I thought of that," remarked Grace, quietly. "It seems to me that
+Richard attached too much importance to the matter."
+
+"That remains to be seen. Now, supposing Valentin to be concerned, with
+the nurse, in the plot. He of course does not think, at the start, that
+the possession of the cigarettes would involve him in the affair,
+because he does not know that Monsieur Duvall has found the one in the
+grass. Your husband, however, asks Mary Lanahan what kind of cigarettes
+Valentin smokes. She at once becomes suspicious, and at the first
+opportunity warns Valentin, by letter, to destroy them. That shows
+clearly that they are working together."
+
+"Undoubtedly. But meanwhile the cigarettes are stolen from Valentin's
+room by a man with a dark beard, who subsequently enters Mr.
+Stapleton's house. For that, I confess, I can find no explanation."
+
+"Nor I. The destruction of the cigarettes could be of no importance to
+anyone, except to the kidnappers themselves. It is of course possible
+that someone else in Mr. Stapleton's house--Francois, for instance--is
+concerned in the plot."
+
+"But the man who took the cigarettes had a black beard, while Francois
+is smooth shaven."
+
+"I know. But it might have been a disguise."
+
+"I do not think so. The man I saw was taller than Francois, and not so
+heavily built."
+
+The Prefect considered the matter for a moment. "You are certain that he
+entered the Stapleton's house?"
+
+"Absolutely certain. I saw the gate close behind him."
+
+"Then I can only say that, so far, the matter is inexplicable. Now let
+us come back to Valentin. He claims to be working to capture the
+kidnappers--in order to clear the nurse, whom he loves."
+
+"That is as I understand it."
+
+"He denies that he smokes, yet offers no explanation of the presence of
+the cigarettes in his room."
+
+"None. Further, someone sends a note to Valentin, advising him that the
+writer is suspicious of Francois--suggesting that he watch him. Can this
+mean that Francois is in the plot, and they fear he may be
+weakening--preparing to turn against them?"
+
+"It certainly looks that way."
+
+"I wish I could see one of these famous cigarettes."
+
+Grace laughed suddenly. "Why," she exclaimed, "I have one in my
+pocketbook. I had quite forgotten it." She opened her purse and took out
+the slender white cylinder.
+
+Lefevre examined the thing closely. "An Egyptian cigarette of American
+make," he mused. "Expensive, here in Paris, and rarely used, except by
+Americans."
+
+"That is true; yet I understand that this man Valentin has lived a great
+deal in America."
+
+For a moment the Prefect did not reply. Then a puzzled look crossed his
+face. "This is a woman's cigarette," he exclaimed. "No man would smoke
+such a thing." He brought his hand down sharply upon his knee. "My
+girl, it is not impossible that the child was stolen not by a man at
+all, but by a woman."
+
+"A woman, apparently, that both Valentin and the nurse are trying to
+shield."
+
+The Prefect sat for a moment buried in thought. Then he glanced at Grace
+keenly. "It seems to me," he remarked, in a quiet tone, "that we should
+endeavor to determine whether or not Mrs. Stapleton is in the habit of
+using cigarettes."
+
+"Mrs. Stapleton!" gasped Grace, in amazement.
+
+"Yes. I confess the idea is a new one, to me; but it may prove of
+interest."
+
+"But why should the boy's mother wish to kidnap him?"
+
+"I do not know. There is but one point of significance. During the past
+week my men have, naturally, questioned Mrs. Stapleton closely as to her
+movements during the past two or three months. They did this, to
+determine, if possible, whether the criminals were of Paris, or from
+some other place, where Mrs. Stapleton may have been, with the child,
+during the past winter. You know these fellows work in bands, and have
+their regular field of operations."
+
+"I see. And where had she been?"
+
+"Monte Carlo!" The Prefect uttered the two words significantly.
+
+Grace was quick to grasp his meaning.
+
+"Then you mean that possibly Mrs. Stapleton may have lost large sums at
+the gambling tables, and, fearing to tell her husband of her losses, has
+enlisted the services of the nurse, and of her friend Valentin, and
+spirited the child away for a few weeks, in order to get the sum of one
+hundred thousand dollars from her husband without his knowledge?"
+
+"It is by no means impossible. I would recommend that you investigate
+the matter thoroughly. If we find that Mrs. Stapleton uses gold-tipped
+cigarettes of this variety, it may go far toward a solution of the whole
+affair."
+
+Grace, remembering Mrs. Stapleton's grief-stricken appearance, felt that
+the clue was a very slender one, but determined to follow it up,
+nevertheless.
+
+"Now," went on the Prefect, "we come to the sudden and most unexpected
+appearance of Valentin, clinging to the rear of the automobile that
+brought you back to Paris tonight."
+
+"As I have told you, he claims to have clambered into Mr. Stapleton's
+car."
+
+"Driven by Francois?"
+
+"Yes."
+
+"And you say the man who drove the car had a black beard--the same man,
+in fact, who broke into Valentin's room and stole the cigarettes?"
+
+"Yes."
+
+"Then either Valentin is lying, or the man with the black beard is
+Francois. Let us look at his story from both sides. If he is telling the
+truth, then Francois is one of the kidnappers."
+
+"So it would seem. You are having him watched, you say?"
+
+"Yes. My men report that he did leave the house, in Mr. Stapleton's
+automobile tonight, at about nine o'clock. That would seem to agree with
+Valentin's story. They also report that he returned about eleven,
+alone."
+
+"They did not follow him?"
+
+"No. It is impossible to do so, in another car, without arousing his
+suspicion, and putting him on his guard. We do not wish him to know that
+he is being watched."
+
+"But Mr. Stapleton must know where he has been--why the car was out."
+
+"Yes. We have questioned him. He says the man reported that the gasolene
+tank was leaking, and that he ordered him to have it repaired at once."
+
+"And was it repaired?"
+
+The Prefect smiled. "Yes. The car was at a garage in the Boulevard St.
+Michel from half past nine until half past ten."
+
+Grace fell back, astonished. "Then Valentin is lying!" she cried.
+
+"So it seems; unless, of course, Francois took out another car from the
+garage, while his own was being fixed."
+
+"They would know that at the garage."
+
+"They deny it. But these fellows all hang together. They would think
+nothing of protecting a brother chauffeur, in the matter of a little joy
+ride."
+
+"Valentin says nothing about this, in his story."
+
+"He may have omitted it, as an unimportant detail. I mean that he may
+have slipped into the second car, as he did into the first, without
+being observed. It was dark of course. He may not have thought it
+necessary to mention it. All this, of course, is on the assumption that
+he is telling the truth. Now let us say that he is lying--that the man
+with the black beard is not Francois, but someone else concerned, with
+Valentin in the plot. What is the purpose of his tale?"
+
+"I cannot imagine. Can you, Monsieur?"
+
+"No, not immediately. The first contradiction, of course, is this. If
+Valentin and the man with the black beard are working together, why
+should the latter have broken into his room to get the cigarettes?"
+
+"There seems no sense to it."
+
+"Yet he may have realized the danger of the cigarettes being in
+Valentin's possession, and instead of trying to warn him simply came and
+took them away. It is not a particularly plausible explanation; but let
+us admit it, for the moment, in order to get ahead with our reasoning.
+Suppose Valentin, the man with the black beard, and Mary Lanahan, the
+nurse, to be all working together, either with Mrs. Stapleton, or with
+outside parties. They have the child safely hidden. They abduct you, and
+send the message to Mr. Stapleton through you. They do not trust you,
+knowing, no doubt, that you are an agent of my office. They send
+Valentin along, on the back of the machine, to pretend to be an enemy of
+theirs trying, like yourself, to recover the child. He thus gets into
+your confidence. He advises you to report your message from the
+kidnappers to Mr. Stapleton at once. He questions you, and learns that
+you do not know the location of the house where the child is hidden. He
+then offers to show you as nearly as he can where the house is located.
+If he is in league with the kidnappers, he will take you, and the men
+whom tomorrow I shall send with you, to some location miles removed from
+the actual point where the child is concealed, and you will waste the
+day in a useless search. Decidedly it would be a clever move on their
+part."
+
+"It certainly would."
+
+"Further, you told this fellow that you had a plan to capture the
+scoundrels. You are to acquaint him with that plan, tomorrow afternoon.
+If you do so, he will no doubt get to the telephone on some pretext and
+warn his comrades of what you intend to do. I strongly recommend that
+you put no faith in the fellow whatever."
+
+"Still, you would advise trying to locate the house, as he suggests?"
+
+"Yes, we may be wrong about him. We must leave no stone unturned. And
+now we come to your interview with Mr. Stapleton. You gave him the
+message, of course. What did he say?"
+
+"He said that he intended to carry out the instructions I gave him to
+the letter--pay these fellows their money, and get back the boy."
+
+Monsieur Lefevre uttered an exclamation of anger. "Sacre! He must not do
+that! The stupid fellow! He will spoil everything!"
+
+Grace laughed quietly to herself. "Hardly stupid, Monsieur! The poor man
+is half mad over the boy's loss. He will do anything, to get him back. I
+can scarcely blame him."
+
+The Prefect held out his hand. "I beg your pardon, my child. You are
+right. It is perhaps but natural for him to feel as he does. But there
+are other things at stake, than the recovery of the child. For Monsieur
+Stapleton to pay over this huge sum to these criminals, and then to
+allow them to escape, is not only a grave reflection upon the efficiency
+of the Paris police, but is an injustice to the public as well. If these
+men are successful in this attempt, they will make others. Other
+children will be stolen. I cannot permit it. It must be prevented at all
+costs. These men must be brought to justice."
+
+"How can you prevent it, Monsieur? Mr. Stapleton is determined."
+
+"That, my child, is the question. I cannot stop Monsieur Stapleton if
+he wishes to drive out the road to Versailles and toss a hundred
+thousand dollars into the first automobile that passes him, showing a
+blue light." He rose and began to walk up and down the room.
+
+"I have a plan, Monsieur," said Grace, quietly.
+
+"What is it, my child?" The Prefect regarded her with an indulgent
+smile. He was very fond of Grace. He regretted that he had been unable
+to secure the services of her husband in this case. He knew, from past
+experience, her cleverness; but he did not believe that in a matter of
+this sort she would be able to outwit men who were probably among the
+shrewdest criminals in Paris.
+
+"First," said Grace, "we will have the location pointed out to us by
+Valentin thoroughly searched."
+
+"Assuredly! It will, however, probably result in nothing. Even if
+Valentin is telling the truth, these fellows will beyond question have
+moved the child before now to prepare for the work of tomorrow evening."
+
+"Possibly. At any rate, we will try. After that, I shall want Valentin
+to drive a motor car for me. He is an accomplished chauffeur."
+
+"You will take him into your confidence, then?" asked the Prefect, in
+some alarm.
+
+"No. I shall tell him nothing, except that he is to drive the car, and
+where."
+
+"Very well. But be careful. What next?"
+
+Grace leaned over and spoke to the Prefect in low tones for several
+minutes. He listened to what she said, occasionally smiling, and nodding
+his head. Presently he brought his hand down sharply upon the table.
+"Bravo!" he exclaimed. "You were born to be a detective. We will get the
+kidnappers, the money, and in all probability the child as well. I
+congratulate you!"
+
+"You think it will work, then?"
+
+"I do not see how it can fail. It is an inspiration. I shall certainly
+feel very well satisfied indeed, if I can return to Monsieur Stapleton
+both his child and his money, and at the same time place the kidnappers
+behind the bars. I could never permit it to be said that the police of
+Paris would knowingly allow a desperate band of criminals to get away
+with half a million of francs without lifting a hand to prevent it." He
+rose and glanced at his watch. "Come, my child. It is after midnight.
+You have had a long and exciting day. You had better get some rest."
+
+Grace rose. "Richard seemed awfully puzzled when he saw me."
+
+"Did he?" The Prefect laughed mischievously. "Really it is a great joke
+upon him. To be within a step of his own wife, and not to know her!"
+
+Grace seemed scarcely to appreciate the humor of the situation. "I think
+it's a shame," she said, "Poor Richard. He'll never forgive me. I really
+think I ought to tell him."
+
+Monsieur Lefevre shook his head. "If you do that, my dear child,
+everything will be spoiled. He will insist upon your dropping the case
+at once, and that would certainly not be fair to me."
+
+"But, Monsieur, after all, you really do not need me, with all the
+clever men you have upon your staff."
+
+"Who knows? Perhaps you may succeed, where they will fail. I have great
+faith in the intuition of a woman. And already you have advanced the
+case further in forty-eight hours than my men have done in ten days. It
+was a chance, I will admit, that these rascals should have chosen you to
+deliver their demands to Monsieur Stapleton. I confess I do not
+understand their reasons for doing so. They must have known that
+besides telling your story to him, you would also tell it to me. It may
+have been sheer bravado on their part--it is a characteristic, I have
+noted, in many criminals. They seem to glory in defying the police.
+These fellows, no doubt, think that they have matters so arranged that
+capture is impossible. I think we shall give them a little surprise."
+
+He turned to the door, and held it open, allowing Grace to pass into the
+hall. "Good night, my child," he called out to her, as she began to
+ascend the stairs. "I think I will smoke one more cigar."
+
+As for Grace, she lay awake a long time, thinking of Richard, of their
+home in the country, of the happy hours they had spent there--before
+this unexpected interruption to their honeymoon. It seemed very queer to
+her, to be lying there, alone. She had not gotten used to it. And
+somewhere, in this big city, Richard was also sleeping--and she not with
+him! The excitement of the affair was beginning to die out. The meeting
+with Richard on the boat, which she had planned when she set out from
+home, had not materialized. She had postponed this meeting, in her
+thoughts, until his arrival in Paris, and now--he had come, and still
+she had not been able so much as to touch his hand. She finally went to
+sleep, devoutly praying that tomorrow, and the capture of the
+kidnappers, would mark the end of their needless and cruel separation.
+
+
+
+
+CHAPTER IX
+
+
+Promptly at eight o'clock the next evening Mr. John Stapleton left his
+house in the Avenue Kleber, in a big French touring car, with Francois
+at the wheel.
+
+The car presented no points of peculiarity, being like a thousand others
+to be seen any evening upon the streets of Paris. It was of large size,
+high powered, and painted a green so dark as to be almost black.
+
+Mr. Stapleton sat in the tonneau, wearing a dark blue serge suit, and a
+Panama hat. In his left hand he clutched a small package, about the size
+of a cigar box. In the package were banknotes amounting to one hundred
+thousand dollars.
+
+Close beside his right foot lay a rubber bulb, from which a short pipe
+extended through a hole bored in the side of the car. The end of the
+pipe held a small brass nozzle. It projected but a short distance beyond
+the body of the car, and in the dim light of early evening was quite
+invisible.
+
+Mr. Stapleton told his chauffeur to drive out the road toward
+Versailles. "I feel like getting some fresh air," he added. "It's rather
+warm, tonight." Inwardly he was burning up with excitement.
+
+From Paris to Versailles is a matter of some fourteen miles. Mr.
+Stapleton's car proceeded slowly. He wanted to run no chances of missing
+the car with the blue light.
+
+At the Porte de Versailles he paused long enough to see Richard Duvall,
+standing in the shadow of the gateway. Then he passed outside of Paris.
+
+There were many automobiles and other vehicles on the road. The evening
+was a pleasant one, and all Paris seemed out taking the air. The
+majority of the vehicles were coming toward the city. He observed a car,
+some distance behind him, containing a single occupant, a man of middle
+age, but paid no attention to it. His eyes were strained to detect in
+the cars approaching him some evidence of the signal light which was to
+rouse him to sudden action.
+
+He noticed that Francois, like himself, was carefully scrutinizing each
+car as it approached them. He wondered if the chauffeur could have any
+idea of the purpose of his expedition; but presently dismissed the
+thought as entirely unlikely, and devoted himself to the passing cars.
+
+He had proceeded perhaps four or five miles beyond the fortifications,
+when he saw a large car approaching slowly from the direction of
+Versailles. It contained but two persons, the chauffeur, and a heavily
+veiled woman.
+
+The chauffeur, who was keenly observing the machine in which Mr.
+Stapleton sat, began to swerve to the right side of the road, so as to
+pass as closely to the banker's car as possible. At the same moment
+there showed through the gathering darkness a brilliant spot of blue
+light in the tonneau where sat the woman.
+
+Mr. Stapleton was on his feet in an instant. The two cars approached
+each other rapidly. It was necessary for him to act with great
+quickness. He shifted the package containing the money from his left
+hand to his right, and a moment later had tossed it lightly into the
+other car.
+
+He saw at once that it landed safely within, and at the same instant he
+pressed his foot down hard upon the rubber bulb. In a moment the car
+with the blue light had swept past, and was disappearing rapidly in the
+direction of Paris.
+
+Mr. Stapleton leaned forward and addressed Francois in a voice which
+quivered with excitement. "Drive home at once," he commanded.
+
+In a moment he was following the first car toward the city.
+
+He did not notice, as he swept down the darkening road, the car which
+had been following him all the way from Paris. It continued on its way
+toward Versailles. In it were two people. At the wheel sat a man who
+bore, in the semi-darkness, a striking resemblance to Francois, Mr.
+Stapleton's chauffeur, while in the rear sat a figure, in dark suit and
+Panama hat, which seemed for all the world like that of the banker
+himself. Had a casual observer not seen Mr. Stapleton turn back toward
+Paris, he would have concluded that he was still on his way toward
+Versailles.
+
+The occupants of this second car also appeared to be keenly watching the
+various automobiles which passed them, as though expecting some signal,
+some recognition; yet, in spite of their eager and expectant glances,
+they seemed doomed to disappointment.
+
+At last Versailles was reached. The elderly man in the tonneau gave a
+short command, his chauffeur turned the car about, and they began to
+return to Paris. Nothing further whatever happened on the Versailles
+road.
+
+Meanwhile, Richard Duvall, at the Porte de Versailles, was carefully
+scrutinizing the various incoming machines that passed the gate and
+entered the city. With a brilliant electric searchlight he examined
+their bodies and wheels, looking always for the telltale red stains
+which would identify the kidnappers' car. Beside him stood Vernet, one
+of the Prefect's assistants, with whom Duvall had become well acquainted
+during his former stay in Paris.
+
+"Well, Monsieur Duvall," remarked the latter, "a most ingenious
+plan--this of yours. I wonder if it will be successful?"
+
+"I feel sure of it."
+
+"I hope you are right." He looked at his watch. "Half past eight. About
+time, I should think, from what you tell me. Here is a big fellow, now.
+A Pasquet, by her looks. Six-cylinder, too."
+
+Duvall glanced at the oncoming car. A wagon which preceded it was just
+passing the gates. The big Pasquet slowed up, and almost stopped.
+
+The detective threw the rays of his searchlight on the body of the car,
+then started back with an exclamation. From one end to the other, the
+dark green finish of the sides and wheels was spattered and streaked
+with bright red paint. Dust had settled in it, in places, especially on
+the wheels; but above, on the doors, it was clear and unmistakable.
+
+"Vernet," he shouted, excitedly, "it is the one! Quick! Don't let them
+get away."
+
+Vernet stepped up to the quivering motor. At the wheel sat a young man,
+quite composed. In the tonneau, a veiled woman reclined at ease. In her
+hands she held a brown paper package.
+
+She leaned toward Vernet, and spoke a single word to him. Duvall did not
+hear what it was; but its effect upon the Prefect's man was
+instantaneous--electrical. He stepped back and raised his hat. "Pardon,
+Madame," he said, and the Pasquet rolled through the gate and into the
+streets of Paris unmolested.
+
+Duvall had sprung forward, and, as he did so, swept the occupants of the
+car with his electric searchlight. Suddenly he drew back in amazement,
+just as Vernet allowed the car to pass on. He could scarcely believe
+that what he saw was a reality. There was the big black car, its body
+and wheels plentifully bespattered with the identifying red stain--and
+there, at the wheel, sat Alphonse Valentin, while the veiled woman in
+the rear was--Grace!
+
+He did not know it was Grace--he did know that it was the woman who had
+been with Valentin in his room, who had brought the message from the
+kidnappers to Mr. Stapleton, who, in some far off and intangible way,
+reminded him of Grace.
+
+There she sat, in her hand the package containing Mr. Stapleton's
+money--and Vernet doffed his cap to her, and permitted her to go on! Was
+this woman, then, hoodwinking even the police?
+
+He sprang to Vernet's side. "Stop them!" he cried, in a hoarse voice.
+"They are the ones I am after."
+
+Vernet shook his head. "Impossible, Monsieur. They are given safe
+conduct by Monsieur the Prefect himself."
+
+"But--they are thieves--kidnappers!"
+
+Vernet shrugged his shoulders. "It may be so, Monsieur Duvall; but my
+orders are to let them pass."
+
+The detective ground his teeth, helpless. His scheme for identifying
+the criminals had worked perfectly. He had found them, only to see both
+them and Mr. Stapleton's hundred thousand dollars as well slip quietly
+through his fingers. He cursed the whole police force of Paris roundly,
+in his anger.
+
+The arrival of another car distracted his attention. It was Mr.
+Stapleton, hurrying home, in the hope of finding his boy. Duvall did not
+stop him. The banker was evidently thinking of nothing but his lost son.
+
+Several other cars passed. Duvall had no interest in them. He was about
+to turn away, with the intention of hunting up Mr. Stapleton and
+learning whether or not the boy had been returned to him, when he heard
+a familiar voice calling him by name. He turned. It was Monsieur
+Lefevre, in a big dark green car.
+
+"Mon Dieu! Duvall!" the Prefect cried, in pretended surprise. "You here!
+In Paris! Or do my eyes deceive me?"
+
+The detective looked a bit sheepish. He realized that in not calling on
+his old friend before now, he had been guilty of an apparent rudeness
+which Monsieur Lefevre might justly resent. "Monsieur," he cried, "it is
+indeed I." He put out his hand, and grasped that of his old chief
+warmly. "A little matter of business brought me to Paris. I have only
+just arrived."
+
+"Indeed." The Prefect's eyes twinkled. "I hope, my dear fellow, that
+your other engagements will permit you to come and see me before long."
+
+"I shall come this very evening, Monsieur. In fact, I have a matter of
+the utmost importance to discuss with you. Shall you be at liberty?"
+
+"In an hour, _mon ami_. Until then I have other things to occupy me.
+Come to the Prefecture in an hour. I shall be waiting for you. For the
+present, adieu." He called an order to his chauffeur, and drove rapidly
+off into the darkness.
+
+Duvall turned on his heel and began to look for a taxicab. "Good night,
+Vernet," he called out, as he went up the street.
+
+In half an hour, he had reached Mr. Stapleton's house. He found the
+unfortunate banker striding up and down his library in a towering rage.
+"The fellows have deceived me!" he cried. "They have not brought back my
+boy. Did you see anything of them? Tell me!" He grasped Duvall nervously
+by the arm.
+
+"The car into which you threw the package of money contained, besides
+the chauffeur, but one occupant, a woman, did it not?"
+
+"Yes--yes! Did you get her?"
+
+"No."
+
+"Why not? Did your scheme to identify the car fail to work?"
+
+"On the contrary, it worked perfectly. I stopped the car at the barrier.
+The woman in it had the package of money in her hand."
+
+"And you did not arrest her! In Heaven's name, why not?"
+
+"The police would not permit me to do so. The woman was the same one who
+brought you the message last night, the supposed agent of the police.
+They allowed her to pass the gates."
+
+"What?" the banker fairly shouted his question. "This is ridiculous! Is
+the woman a criminal, or is she a detective? She cannot be both, and if
+she is the latter why was she in that car, with my money in her hand?"
+
+"I do not know. But I mean to find out very shortly."
+
+"How? I'd like to know!"
+
+"I am going to see the Prefect of Police at once."
+
+Mr. Stapleton sank into a chair, and groaned. "I had hoped to have Jack
+with me by now. His poor mother is distracted. Isn't there anything, Mr.
+Duvall, that you can do?"
+
+"I hope to answer that question better, Mr. Stapleton, after I have seen
+Monsieur Lefevre. If this woman, and her companion, Valentin, are really
+the kidnappers, they are in Paris, and we shall be able to lay our hands
+on them without difficulty. If they are not, your money, at least is
+safe. I must leave you now; but as soon as I learn anything, I will
+report to you at once. Good night."
+
+He left the house, more mystified than he had ever been in his life.
+From the start, this case had apparently been one in which all the clues
+led to absurd contradictions, or else to nothing at all.
+
+In fifteen minutes he was at the Prefecture.
+
+Monsieur Lefevre sent out word that he would be occupied for a few
+moments, and the detective sat down as patiently as possible, to wait.
+
+
+
+
+CHAPTER X
+
+
+The events of the Versailles road left Grace Duvall in a high state of
+good humor. The plan she had suggested had been a success--at least so
+far as her own part in it was concerned. How Monsieur Lefevre had fared,
+she did not yet know. She looked down at the brown paper package she
+held in her hand, and ordered Valentin to drive to the Prefecture.
+
+The day had been an eventful one. Immediately after breakfast Grace had
+gone to Mr. Stapleton's house and had a long interview with Mrs.
+Stapleton. That lady, apparently quite prostrated from worry and alarm
+over the fate of her son, received her in her boudoir, where she lay, a
+charming picture, upon a divan.
+
+Grace had no more than entered the room, when she detected the odor of
+cigarette smoke, faint but unmistakable. She glanced at the table which
+stood beside the divan upon which Mrs. Stapleton lay. On it, a tiny
+porcelain ash receiver contained a fluffy mass of gray-white ashes, and
+the half smoked remains of a cigarette. The tip, partly covered by the
+ashes, was of gold.
+
+The girl engaged her hostess in a long conversation, quieting her fears,
+which seemed real enough, and predicting the early recovery of her boy.
+It was quite evident that Mrs. Stapleton was terribly nervous. No doubt
+this accounted for the cigarettes. Although Grace did not use them
+herself, she knew how their quieting effect on the nerves made them
+almost necessities, at times, to their devotees.
+
+Presently she observed that Mrs. Stapleton held within her left hand,
+concealed beneath the folds of her kimono, a small pasteboard box, a box
+of cigarettes. Grace determined upon a bold move.
+
+"May I have one of your cigarettes, Mrs. Stapleton?" she asked, in her
+sweetest manner. "I've forgotten to bring any with me--and--you know how
+it is."
+
+Mrs. Stapleton's features relaxed into something approaching a smile.
+She had been lying there wondering whether she dared offer one to Grace,
+and thus be able to sooth her own overstrained nerves. She brought
+forth the box and extended it toward her visitor. Grace took one of the
+tiny cylinders and lit it. _It was of the same make as the one she had
+secured in Alphonse Valentin's room!_
+
+She took her departure a little later, wondering greatly. The whole
+affair had begun to take on an air of baffling contradiction.
+
+She spent the rest of the morning, and most of the afternoon, searching
+the houses near the point on the road to Versailles indicated by
+Valentin. With her were three men from the Prefect's office--silent,
+able men, in plain clothes, who pretended to be keepers from the _Jardin
+des Plantes_, in search of a dangerous cobra, which was supposed to have
+escaped from its cage the night before.
+
+The terrified householders threw open their doors with unassumed
+alacrity. The suggestion of a deadly reptile lurking in their gardens
+was a veritable open sesame. Yet no traces of the missing boy were
+found, and, more remarkable still, Grace was unable to identify any of
+the many gardens as the one in which she had seen the child playing with
+the spaniel. This disappointed her greatly. She knew well that, if
+Valentin was telling the truth, the garden was here; yet, although they
+visited every house within a quarter of a mile, they were unable to
+locate it. She remembered now that in her agitation, her eager
+examination of the child, she had not fixed upon her mind any salient
+point in the garden itself. All that she remembered was a bit of grass,
+a gravel walk, and the child playing with the dog. A dozen of the little
+enclosures presented similar features. She returned to the prefecture,
+baffled.
+
+"The fellow is undoubtedly lying," had been Monsieur Lefevre's comment.
+"He is trying to throw you off the track, in order to protect the nurse,
+and possibly Mrs. Stapleton as well. I should not be surprised to find
+that the boy's mother is the guilty person."
+
+Grace did not agree with him; so she said nothing. In spite of the fact
+that Mrs. Stapleton used cigarettes similar to those which seemed in
+some queer way to be at the bottom of the mystery, she had an intuitive
+feeling that the grief which the banker's wife showed was entirely real.
+
+At half past seven, Grace left the prefecture in a high-powered car,
+furnished by Monsieur Lefevre. Alphonse Valentin was at the wheel. In
+her hand she held a pocket electric searchlight, across the front of
+which had been affixed a circular bit of blue glass.
+
+At ten minutes to eight she arrived at Versailles. She at once ordered
+Valentin to turn and drive back toward Paris at moderate speed. She did
+not take him into her confidence regarding what she proposed to do, but
+kept a keen watch for the car containing Mr. Stapleton.
+
+Her plan had worked. Mr. Stapleton, seeing her signal, had tossed her
+the package of money--she only hoped that the other part of her plan had
+been carried out with equal success.
+
+The other part of the plan had been this: Monsieur Lefevre, who in build
+and general appearance was not unlike Mr. Stapleton, was to follow the
+latter's car in a machine of the same make and general appearance. He
+was to be driven by a chauffeur made up to resemble Francois
+sufficiently to be mistaken for him in the dim light of early evening.
+He himself was to make such alterations in his appearance and dress as
+would enable him to pass, under a cursory examination, for Stapleton. In
+the bottom of the car two armed men lay concealed.
+
+When the car containing Mr. Stapleton turned back toward Paris, after
+having unwittingly delivered the money to Grace, the Prefect would
+continue on toward Versailles. He would know that the car containing the
+kidnappers was still ahead of him; since, had it not been, it, instead
+of Grace's car, would have signaled Mr. Stapleton.
+
+Grace had started out from Versailles especially early, convinced that
+the kidnappers would not leave there until eight, at least. In this
+assumption she was correct. The car containing the kidnappers was, at
+that moment, creeping toward Paris some two miles in her rear, looking
+everywhere for Mr. Stapleton.
+
+The Prefect pursued his way toward Versailles in anxious expectancy.
+Each moment he thought to see the blue signal flash from the various
+cars which passed him. When it came, his men were to spring up, and at
+once bring the other car to a standstill by firing their guns, heavily
+charged with buckshot, at its wheels. A punctured tire, and the thing
+was done. His men, assisted by the chauffeur, would then overpower the
+occupants of the other car before they could realize what had happened.
+In it they hoped to find the child.
+
+The plan was well conceived; but unfortunately it did not work.
+Whatever the reason, none of the cars which passed the Prefect on his
+way to Versailles displayed the telltale blue light. All seemed but
+peaceable automobilists, intent on reaching Paris and its restaurants as
+quickly as possible. Had his disguise been penetrated? He could not
+believe it. He returned to the Prefecture in great disgust, wondering in
+what way matters had gone wrong.
+
+Grace was waiting for him, an eager smile on her face. "Here is the
+money," she said, placing the package on his desk. "Did you get the
+men?"
+
+"No." The Prefect flung himself into a chair. "They did not signal."
+
+"But why, I wonder?" The failure of her plan was extremely annoying.
+
+"I can think of but one reason. There must have been some way in which
+these fellows knew the Stapleton car when they approached it--some
+signal, perhaps, that I was unable to give."
+
+"But no such signal was mentioned in the instructions I brought to Mr.
+Stapleton. He gave none, as we approached him."
+
+"Did you observe anything peculiar about the appearance of his car,
+anything that might have served as a clue to enable these fellows to
+recognize it, even in the dark, with certainty?"
+
+Grace thought a moment, then her face fell. "There was one thing that I
+noticed as Mr. Stapleton's car came up to us; but I am afraid I failed
+to realize its significance at the time."
+
+"What was it?"
+
+"The electric headlight on the side nearest to me was working very
+badly. In fact, it seemed to be almost out. The other was burning
+brilliantly."
+
+The Prefect sprang to his feet. "Sacre!" he exclaimed. "Of course. The
+thing is as plain as the nose on your face!"
+
+"But who--"
+
+"Francois! The fellow is in this thing up to his neck. _He_ claims to have
+been asleep when the boy was stolen. _He_ drives the car which brings
+you back, after your abduction. _He_, disguised, steals the box of
+cigarettes. _He_ fixes the lights so that the kidnappers are advised,
+not only beyond any doubt that they are signaling the right car, but
+that all is safe--that Monsieur Stapleton has no detectives or members
+of the police hidden in his tonneau. The thing is perfectly clear.
+Believe me, my child, had there been anyone in that car with Mr.
+Stapleton, those lights would have both been burning with equal
+brightness, as mine were. They did not give me the signal, when they
+passed me, because the lights failed to tell them that all was well."
+
+Grace looked up quickly. "Then, if that is true, Francois knew that Mr.
+Stapleton had thrown the money into the wrong car."
+
+"Undoubtedly, and by this time, no doubt, his confederates know it as
+well. Naturally the child has not been delivered. We are just where we
+were before."
+
+"You will arrest Francois at once, I suppose."
+
+"No. It will be useless. By leaving him free, we may learn something. By
+locking him up, with no tangible evidence against him, we accomplish
+nothing at all."
+
+"Then what do you advise?"
+
+"You will return the money to Mr. Stapleton at once. You can tell him,
+if you wish, how it came into your possession. He will be furious, of
+course; but he must understand that the capture of these scoundrels is
+quite as important to the city of Paris as the recovery of his son. We
+have done our best, and failed. We must try again."
+
+"Richard was at the Porte de Versailles," remarked Grace, quietly. "He
+tried to stop my car."
+
+"Yes. I saw him. He is coming here at once."
+
+The girl rose, in nervous haste. "I must go, then. It would be most
+unwise to have him find me here."
+
+There was a quick knock at the door. The Prefect rose, and opened it;
+then turned to Grace with a grim smile. "Your husband is waiting in the
+anteroom," he whispered.
+
+"But--what shall I do?"
+
+"Wait in here." Monsieur Lefevre opened the door which led to his
+private office. "You can hear everything quite plainly. From what you
+tell me, I should not be surprised if he insisted upon your arrest at
+once."
+
+"It isn't fair to him. Poor Richard! I'm afraid he'll never forgive me
+for all this."
+
+"Nonsense! You are engaged in a very laudable attempt to recover Mrs.
+Stapleton's child. So is he. Your interests are identical. Only," he
+paused with a significant smile, "from my standpoint, I should much
+prefer that the credit for the boy's recovery should belong to the
+police of Paris, of which you, for the time being, are one."
+
+Richard Duvall came into the Prefect's office, somewhat ill at ease. The
+room, familiar to him because of the events of the past, reminded him
+forcibly of Grace--who had, indeed been upon his mind constantly for the
+past few days. It was here, in this very room, that she had first told
+him that she loved him--during the exciting pursuit of Victor Girard,
+and the million francs. He gazed about at its familiar aspect, and
+sighed.
+
+"Sit down, my dear Duvall," said the Prefect, shaking hands with him
+warmly. "What, may I ask, brings you to Paris, at the cost of
+interrupting your honeymoon? I had supposed that nothing could be of
+sufficient importance for that. In fact, had I known you would consider
+it for a moment, I should have cabled to you, to give me your assistance
+in a most trying case."
+
+"What case, Monsieur?"
+
+"The mysterious kidnapping of the child of Monsieur Stapleton."
+
+"It is that very case that brings me to Paris. I am in Mr. Stapleton's
+employ."
+
+Monsieur Lefevre affected to be greatly surprised. "Is it possible,
+_mon ami_? That is bad news indeed. This fellow Stapleton no longer has
+confidence in my office. He retains you to do that which he believes I
+shall fail to do. I am sorry, my dear Duvall, that we are on opposite
+sides of the fence."
+
+"But, Monsieur, I did not know that you wanted me. Mr. Stapleton is an
+old friend. I could not refuse to come to his assistance."
+
+Lefevre's eyes twinkled. "Have you made any progress, then, my friend?"
+
+"Yes. Tonight I put in operation a plan whereby I might identify an
+automobile containing the kidnappers, into which Mr. Stapleton had been
+directed to throw a package containing one hundred thousand dollars."
+
+"Indeed. You interest me. And did you succeed in identifying it?"
+
+"I did. I stopped the car, at the Porte de Versailles. I knew it to be
+the one into which the money had been thrown. The car was driven by a
+man named Alphonse Valentin, whom I have every reason to suspect is
+concerned in this affair. Its only other occupant was a woman--whom I
+met last night in Valentin's rooms, and who brought Mr. Stapleton a
+message from the kidnappers. This woman is, I believe, at the bottom of
+the whole thing."
+
+"Indeed. And did you arrest her?"
+
+"No. She claims to be an agent of your office. Vernet, who was at the
+gates at my request, refused to place her and her companion under
+arrest. She got away with Mr. Stapleton's money. I believe, Monsieur
+Lefevre, that you are being made a fool of by a member of your own
+staff."
+
+The Prefect leaned over, and picked up the package containing the money
+which lay upon his desk. "I do not agree with you, my friend. Here is
+Monsieur Stapleton's money."
+
+Duvall started back in his chair, amazed. "Good Lord, Chief, am I losing
+my senses? What is this affair, anyway, a joke?"
+
+"Far from it, Monsieur Duvall. The criminals are still at large. The boy
+is in their hands. We must recover him."
+
+"But--this money--"
+
+"I arranged to get it, in order to prevent Monsieur Stapleton from
+making a fool of himself. I wish to capture these men--not to let them
+blackmail him out of half a million francs."
+
+"Had you not interfered, Monsieur Lefevre, they would have been in my
+hands, by now. I would have had them safely the moment they attempted to
+enter Paris. I knew their car."
+
+The Prefect was filled with curiosity. "How?" he asked.
+
+"My means of a device with which Mr. Stapleton's car was equipped, the
+body of the one into which he threw the money was spattered with red
+paint. I could have identified it anywhere."
+
+"My dear Duvall! I feel that I should beg your pardon. Your plan was
+cleverness itself, and I will admit that, had I not interfered, you
+would in all probability have captured these men. I did not know what
+you had done, of course. Yet in their escape I have one consolation. It
+would have been extremely distasteful to me, to have had Mr. Stapleton
+boast that a private detective in his employ had succeeded, where the
+police of Paris had failed."
+
+"Then it would appear, Monsieur," said Duvall somewhat stiffly, "that we
+are, in this matter at least, in opposition."
+
+"Let us rather say, my friend, in competition." He placed his hand on
+Duvall's shoulder. "You must not blame me, if I feel a pride in my
+office. When you were working for the city of Paris, you, too, felt
+that pride. I am truly sorry that I have not the benefit of your
+services now. However, I think you will admit, _mon ami_, that the young
+woman who is handing this case is no mean adversary." The Prefect
+regarded the detective with a quizzical smile, behind which his eyes
+twinkled merrily.
+
+"Who is this woman?" asked Duvall, quickly.
+
+"Her name is--Goncourt--Estelle Goncourt."
+
+"A Frenchwoman?"
+
+"Partly. I believe her mother was English." The twinkle in his eye
+spread--he smiled upon the detective with expansive good humor. "Why do
+you ask?"
+
+"You will think it strange, perhaps, Monsieur Lefevre, but when I first
+saw Miss Goncourt, she reminded me strongly of my wife."
+
+"Of Grace?"
+
+"Yes. Have you not observed it?"
+
+"Now that you speak of it, perhaps there is something similar in the
+manner--the carriage. But your wife, my dear Duvall, is a blonde, while
+Mademoiselle Goncourt is decidedly a brunette."
+
+"Yes. Of course. But, nevertheless, the resemblance is striking." He
+rose to go. "I hope, Monsieur, that this kidnapped boy may be restored
+to his father very soon. I am anxious to return to America."
+
+"What! Leave Paris so quickly? My dear Duvall, I thought you Americans
+loved our city so well, that you never wanted to leave it."
+
+"Paris is all right, Monsieur; but," he laughed heartily, "I must get
+back to my wife and my farm. I was forced to leave in the very middle of
+my spring plowing."
+
+The Prefect roared. "You--a farmer! Mon Dieu! How droll! Potatoes, I
+suppose, and chickens, and dogs, and pigs--"
+
+"Exactly--and, believe me, Monsieur, they are more to my liking, than
+all the gaieties of Paris. Some day you must make us a visit, and see
+for yourself." He turned toward the door.
+
+"I shall, Duvall, I shall. But first we have to find this boy. What do
+you propose to do next?"
+
+Duvall smiled. "What do you?" he retorted.
+
+"A bottle of champagne, my friend, and a dinner at the Cafe Royale, that
+we find the child before you do!"
+
+"Done! Now I'll be off. Good night."
+
+The Prefect was still laughing when Grace peeped in from the private
+office, to find that Richard had gone. "I think it's a shame to treat
+him so," she said. "The poor fellow! And he _would_ have gotten the
+kidnappers, if we hadn't interfered."
+
+Monsieur Lefevre picked up the package containing Mr. Stapleton's money
+and placed it carefully in his safe. "Tomorrow you must return it to
+him," he said. "And then, I would suggest that you keep a close watch
+upon Mrs. Stapleton. My men have not been keeping her under
+surveillance. We have had no suspicions of her whatever. She may, if she
+is concerned in this matter, be imprudent enough to attempt to visit the
+child."
+
+"And if not?"
+
+"Then watch Francois. If nothing comes of your efforts in either
+direction, I fear that we must wait for the kidnappers to make the next
+move. Of course there is Valentin--"
+
+"Valentin is innocent."
+
+"How do you know that?"
+
+"I have watched him. He did everything in his power, tonight, to assist
+me. Had he been in league with the kidnappers, he could, after he knew
+that I had secured the money, easily have driven the car to some quiet
+spot and taken it from me. I was waiting for some such move; but he, as
+you know, did not attempt it. I am sure that he is doing his best to
+assist us."
+
+"In that event, perhaps you can induce him to tell you the secret of the
+box of cigarettes. I feel sure that this knowledge would go far toward
+solving the entire affair."
+
+"I'll have a talk with him tomorrow."
+
+"Good! And now, if you are ready, we will return home at once."
+
+"Dear old Richard!" said Grace, as the Prefect helped her into his
+automobile. "I wish I were with him tonight."
+
+Lefevre smiled, and patted her hand. "So do I, my dear. But, remember,
+you have only to find Mr. Stapleton's child, and you can return to your
+chickens and your cows with the knowledge that you have done both his
+parents and myself an inestimable service."
+
+
+
+
+CHAPTER XI
+
+
+It was close to eight o'clock next evening when Grace Duvall arrived at
+Mr. Stapleton's house with the package containing the money.
+
+She was accompanied, for safety, by two men from the Prefecture, who
+escorted her to the door.
+
+She had paid a previous visit to the house, during the forenoon; but Mr.
+Stapleton was not at home, and she was informed that he would not return
+until evening.
+
+Mrs. Stapleton she saw again; but her talk with the latter resulted in
+nothing. The poor lady was in utter despair, after the fiasco of the
+night before, and spent the day in her rooms, weeping.
+
+It was quite clear to Grace that her grief was very real. She made up
+her mind that, whatever the mystery of the gold-tipped cigarettes, Mrs.
+Stapleton had nothing to do with it. Nor had the chauffeur, Valentin,
+been more communicative. He refused pointblank to explain the presence
+of the cigarettes in his room, or the reason why Mary Lanahan had
+written requesting him to destroy them. He said that it was a matter
+which concerned only the nurse and himself, and assured Grace that an
+answer to her questions would not assist in the least in recovering the
+missing child.
+
+Mr. Stapleton was awaiting her in the library when she entered. The
+Prefect had telephoned him, advising him that the money was safe, and
+would be returned to him at once. Beyond that, he knew nothing, except
+what Duvall had told him the night before. Consequently he was in a
+decidedly bad humor.
+
+Grace laid the money on the table. "Here is your hundred thousand
+dollars, Mr. Stapleton," she said.
+
+The irate banker glared at her. "I cannot thank you for bringing it
+back, Miss," he growled. "Did I not particularly request that the police
+take no steps in the matter?"
+
+"You did, Mr. Stapleton; but we acted for what we thought to be your
+best interests."
+
+"Hang your thoughts about my best interests! I can take care of them.
+If you had let things alone, I'd have my boy back by now."
+
+"And these men, these criminals, who stole him, would be at liberty to
+do the same thing over again tomorrow."
+
+Mr. Stapleton was silent for a moment. "How did the thing happen?" he
+presently asked.
+
+Grace told him. "The real cause of our failure, we believe, lies at the
+door of your chauffeur, Francois." She explained the reasons for their
+suspicions.
+
+Mr. Stapleton seemed puzzled. "The fellow seems honest enough."
+
+"Where is he now?" Grace inquired.
+
+"He asked permission to visit his people. As I had no use for him this
+evening, I told him he might go."
+
+"Ah! In that event, we may learn something. He is being closely
+watched."
+
+As Grace spoke, a servant entered the room. "There is a gentleman to see
+you, sir," he said to Mr. Stapleton.
+
+"Who is it?"
+
+"He would not give his name. He said his business was urgent."
+
+"Where is he now?"
+
+"In the reception room, sir."
+
+Mr. Stapleton rose. "Excuse me a moment," he said, and went into the
+adjoining room.
+
+The library was separated from the reception room by a short passageway,
+or alcove, in which hung a pair of heavy curtains. Grace sat quietly,
+waiting for Mr. Stapleton to return. Suddenly she realized that she
+could distinctly hear what was going on in the room adjoining. For a
+moment she thought of going into the hall; then a word or two caught her
+attention, and in a moment she was close to the curtains, listening
+intently to a most remarkable conversation.
+
+The man who had asked to see Mr. Stapleton stood in the reception room,
+near a broad window overlooking the street without. He was tall and
+somewhat heavily built; but what at once attracted Grace's attention was
+his heavy black beard. She recognized him at once as the man who had
+broken into Valentin's room to steal the cigarettes, and had later
+driven the car which brought her back to Paris after her abduction.
+
+He was speaking to Mr. Stapleton in a quiet and assured tone, as though
+discussing a topic of no greater importance than the weather.
+
+"Mr. Stapleton," he said, "I have your son in my possession. He is
+quite safe. I gave you an opportunity to have him returned to you last
+night; but you did not avail yourself of it."
+
+"I did my best," exclaimed the astounded banker, mastering his desire to
+take the fellow by the throat.
+
+"That may be; yet my plans were interfered with. You did not carry out
+my instructions."
+
+"I did--to the letter."
+
+The man frowned. "It is useless to discuss the matter now," he growled.
+"I come to give you one more chance. It will be the last--"
+
+"You damned scoundrel!"
+
+The man with the black beard held up his hand. "It will avail nothing,
+Monsieur," he said, calmly, "to excite yourself. If you want back your
+boy, listen to what I have to say."
+
+"Very well. Go ahead."
+
+"First, I want no interference by the police, or by the man Duvall, who
+is acting for you."
+
+Mr. Stapleton drew back in astonishment. "How do you know that Mr.
+Duvall is acting for me?" he said.
+
+"It is my business to know, Monsieur. Let it suffice that I _do_ know.
+If you hope ever to see your child again, you had better listen to what
+I have to say, and carry out my instructions to the letter." His voice
+was harsh, menacing.
+
+Mr. Stapleton directed him by a gesture, to proceed. He was too angry to
+speak.
+
+"Tomorrow night at this hour--eight o'clock--I shall come here, to this
+house, and ask for you. You will hand me a package containing one
+hundred thousand dollars. I will examine the money here, and satisfy
+myself that the amount is correct.
+
+"I shall then leave the house, and walk to the Arc de Triomphe; which,
+as you know, is but a short distance away. At the Arc de Triomphe, I
+shall wait for an automobile, which will stop for me. In that automobile
+I shall drive away. If I get away safely without interference, there
+will be telephoned to your house, within half an hour, the address of
+the place where your boy is to be found. If I do _not_ get away safely,
+that address will _not_ be telephoned to you, and you will not see your
+child alive again. This is your last chance, Monsieur. It is most
+important, I assure you, that nothing should happen to prevent my safe
+departure tomorrow night."
+
+For a moment Grace was undecided as to how she should act. She feared
+greatly, under the circumstances, to make any move which would endanger
+the safety of Mr. Stapleton's child. Yet her duty, as an agent of the
+police, was clear. She must use every effort to effect this man's
+capture, before he left the house.
+
+She knew that she could not reach the street without passing the door of
+the reception room, in which case both Mr. Stapleton and his caller
+would see her. There was nothing to do but telephone. She flew to a
+small alcove room which opened off the rear of the library, in which she
+knew the telephone instrument was located. Once in this small room, she
+closed the door, for fear the others might overhear her, then called up
+the Prefecture. Monsieur Lefevre was out; but she acquainted one of his
+assistants with the circumstances, and requested him to send a man to
+the house at once.
+
+It would take at least ten minutes, perhaps more, for the man from the
+Prefecture to reach the house even though he came by automobile, as he
+no doubt would. What should she do, to keep the man in the reception
+room from leaving before the police should arrive?
+
+The question was solved for her, quite unexpectedly. In opening the
+door of the small room, to re-enter the library, she accidentally struck
+against a chair. The sound aroused both Mr. Stapleton and his visitor.
+The former, who had, in his excitement, completely forgotten Grace's
+presence, appeared at once in the doorway between the two rooms. "Come
+here, Miss Goncourt," he said sternly.
+
+Grace entered the reception room. The man with the black beard eyed her
+keenly. "Ah--a representative of the police, I believe. Our conversation
+has been overheard, then, Monsieur Stapleton?"
+
+The banker was violently angry. He turned to Grace. "You have heard?" he
+demanded.
+
+"Yes."
+
+"Then I insist that you do not interfere in the matter in any way. I
+intend to get my boy back this time, in spite of you all."
+
+Grace made no reply. She saw the man with the black beard eying her
+keenly. "I think, Monsieur, that I had better go," he remarked.
+
+Grace regarded him with a level look. "You cannot leave this house," she
+said. "It is being watched. If you attempt to do so, I will give the
+alarm."
+
+"And for what reason should I stay?" the man inquired calmly.
+
+"I have telephoned to the Prefecture. A man will be here in a few
+minutes, to place you under arrest. I advise you to remain here quietly
+until he arrives."
+
+The kidnapper strolled over to the window which overlooked the Avenue
+Kleber, drew aside the curtain, and looked out. Grace wondered if he was
+making a signal of any sort to confederates outside. He gazed into the
+street intently for a moment, then turned back toward the center of the
+room. "I shall follow your advice, Mademoiselle, and wait," he remarked,
+calmly.
+
+Mr. Stapleton was speechless with rage. He dared not do anything; for he
+knew that he would only lay himself open to a charge of resisting the
+police, and helping a criminal to escape. He sat in his chair, inwardly
+cursing Grace and the entire police force of Paris as well.
+
+None of the three spoke for a considerable time. After what seemed to
+Grace ages, she heard the faint ringing of the doorbell, and presently
+the frightened servant arrived, with the information that a detective
+from the Prefecture was in the hall, and desired to see Mr. Stapleton
+immediately. He had scarcely succeeded in delivering this message, when
+a heavily built man in citizen's clothes shouldered past him into the
+room.
+
+He gazed quickly about. Grace did not remember having ever seen him
+before. "I am from the Prefect of Police," he announced, striding toward
+the kidnapper. "I am here to arrest this man." In a moment the click of
+the handcuffs, as he snapped them upon the wrists of the man with the
+black beard, came to Grace's ears.
+
+The kidnapper smiled pleasantly. "I am quite ready to accompany you, my
+friend," he said.
+
+Mr. Stapleton was regarding the scene in helpless rage. He resented
+bitterly the way in which the police continually interfered with his
+plans to get back his child. In one way, he was glad to feel that the
+guilty man was under arrest; but, if it resulted in the death of the
+missing boy, it would be a tragedy, indeed. He turned to the man with
+the black beard who stood, smiling, near the door. "I hope you will
+understand," he said, "that I have nothing to do with this
+matter--nothing whatever. The presence of this woman here was a pure
+accident. I had forgotten that she was in the next room. I'd be glad
+enough to see you put behind the bars for the rest of your life; but
+not if it is going to prevent me from getting back my child."
+
+The man with the black beard continued to smile pleasantly. "I believe
+you, my friend," he said. "However, there is no harm done. When I return
+tomorrow night--for I shall return, depend upon it, in spite of the
+efforts of this gentleman," he waved his hand lightly toward the man
+from the Prefecture, "I trust that you will have persuaded Monsieur
+Lefevre, and your man Duvall as well, to let me do so in peace. It is
+the only way in which anything can be accomplished--I assure you of
+that." He turned to his captor. "I am ready to accompany you, Monsieur."
+
+The officer started toward the door leading into the hall. He had taken
+but a single step when the servant, with a frightened look upon his
+face, appeared in the doorway. "Mr. Stapleton," he stammered, "there is
+a man here from the office of the Prefect of Police."
+
+Stapleton strode toward the door. "Another?" he exclaimed. "What does
+this mean?"
+
+The man in charge of the kidnapper stepped forward, speaking in a quick,
+low tone. "Leave the matter to me, Monsieur," he whispered. "This
+fellow who has just arrived is an impostor, a confederate. He pretends
+to be an agent of the police, in order to rescue his comrade, who has
+undoubtedly signaled to him from the window. Be good enough to step into
+that room," he pointed to the library, "and let me deal with him."
+
+Mr. Stapleton hesitated. "What do you propose to do?" he asked.
+
+"Quick!" said the other, offering no explanations. "He will be here at
+once." He turned to the astonished servant. "Bring the man in."
+
+The puzzled banker moved toward the adjoining room. "You will accompany
+him, please," the Prefect's man said to Grace. "There may be danger."
+
+"I am not afraid, Monsieur," replied Grace, who did not entirely like
+the way things were going.
+
+The man, however, paid no attention to her remonstrances. "Go--at once,
+I command you, in the name of the law!"
+
+She hesitated no longer, but followed Mr. Stapleton into the library. As
+she did so, the new arrival entered the reception room.
+
+The man with the black beard stood to one side of the doorway. His
+captor advanced toward the newcomer. "I have him here," he exclaimed,
+pointing to the kidnapper, "safely ironed."
+
+"Who are you?" curtly inquired the man who had just entered the room.
+
+"A private detective. Here is your man. Let us get him out of here at
+once."
+
+The official made no reply, but stepped quickly up to the man with the
+black beard. "Come along with me," he said, roughly, and placed his hand
+upon the other's arm.
+
+As he did so, the kidnapper shook his wrists briskly. The handcuffs fell
+clattering to the floor. Without a word he threw his powerful arms about
+the neck of the astonished official, and throttled him into instant
+silence. His companion, no less quick, whipped out a handkerchief, and
+knotted it about the official's mouth. He was unable to utter a sound.
+
+The whole thing was so quickly done that Grace, who was watching the
+room through the curtains in the doorway, had barely time to utter a
+cry, before the newcomer was lying helpless and silent upon the floor,
+choked into insensibility; while the two men, quite evidently
+confederates, made ready to go.
+
+The black-bearded fellow quickly replaced the handcuffs upon his own
+wrists. "Quick, Ramond," he cried. "Let us get out at once."
+
+Grace was by this time in the room. She knew that she must in some way
+prevent these men from escaping. But how--how? They glared at her
+ominously. The younger man drew a revolver. Before any of them could
+speak, the servant appeared in the doorway for the third time. His face
+was pale as death. His knees knocked together from terror as he beheld
+the gleaming revolver, the man lying upon the floor.
+
+"Monsieur Duvall is here!" he gasped, and stood silent.
+
+The man on the floor, recovering his senses, began to struggle to his
+feet. As he did so, Duvall pushed his way past the frightened servant
+and strode into the room.
+
+"Quick, Monsieur Duvall!" the fellow with the revolver cried. "I am from
+the Prefecture. I have one of the kidnappers in irons. The other," he
+pointed to the struggling man on the floor, "is about to escape me. Give
+me your assistance at once!"
+
+Grace was so astounded by the sudden entrance of her husband, as well as
+by the kidnapper's words, that for a moment she remained speechless.
+Duvall bent over the man upon the floor and seized him by the throat.
+
+"Richard! Richard!" Grace screamed, forgetful of Monsieur Lefevre and
+her own disguise. "Look out!"
+
+Almost before the words had left her lips, the man with the revolver
+brought it down with a dull thud upon Duvall's head as he bent over the
+prostrate man; then, grasping his companion by the arm, he rushed from
+the room.
+
+"Richard! Richard!" screamed Grace, throwing her arms about the
+senseless body of her husband.
+
+Mr. Stapleton, who had entered the room, regarded her in amazement.
+"What are you doing?" he exclaimed.
+
+Grace rose, her face white with suffering. "A doctor, quick! He is hurt!
+My God--don't you see? He is hurt!" As she spoke, she fell back,
+fainting, to the floor.
+
+
+
+
+CHAPTER XII
+
+
+When Richard Duvall returned to consciousness, an hour later, he lay
+upon a couch in Mr. Stapleton's library. A doctor, hastily summoned, was
+bending over him. Mr. Stapleton sat grimly in an arm chair. There was no
+one else in the room.
+
+"My wife! Is she here?" the detective cried, as he tried to rise.
+
+The doctor pushed him gently back. "Compose yourself, Monsieur," he said
+in a soothing voice. "You are not badly hurt. Merely stunned for the
+moment. A slight cut--that is all. You will be quite yourself again in
+half an hour."
+
+"But my wife!" He gazed eagerly about the room.
+
+"What do you mean, Duvall?" inquired Mr. Stapleton, calmly. "Why do you
+think your wife is here?"
+
+"A trace of delirium. He will be all right in a few moments. Very usual
+in such cases," the doctor whispered.
+
+"I heard her voice. She called to me by name, just as that fellow struck
+me."
+
+"My dear sir, your mind is wandering. Compose yourself, I beg." The
+doctor attempted to press his patient back upon the pillows.
+
+Duvall passed his hand over his forehead, completely bewildered. "I
+could have sworn I heard her voice," he cried.
+
+"It was Miss Goncourt, the young woman from the Prefecture, that you
+heard, Duvall," remarked Mr. Stapleton quietly. He did not tell the
+detective that Grace, on recovering from her faint, and learning from
+the doctor that Richard's wound was a superficial one only, and not at
+all serious, had sworn them both to secrecy, on the plea that the matter
+was a purely private one, and likely to cause her great unhappiness if
+divulged. Mr. Stapleton had agreed, but had done so only upon her
+agreeing not to acquaint the police with his plans for the following
+night.
+
+She had suddenly conceived a violent animosity toward these fellows who
+had not only baffled both her husband and herself, but had made the
+former a victim of a dangerous assault. She was determined to go to
+work in desperate earnest, to capture them, or locate the child, before
+the following evening. She had promised Mr. Stapleton not to acquaint
+Monsieur Lefevre with the plan for returning the child which the man
+with the black beard had proposed. The situation put her on her mettle.
+She determined to get at the bottom of the whole affair before another
+twenty-four hours had passed. Upon leaving the house she called a
+taxicab, and at once ordered the chauffeur to drive her to the point on
+the Versailles road where, according to Valentin, she had been placed in
+the automobile after her interview with the kidnappers. Here, she
+believed, lay the starting point of the whole mysterious affair.
+
+Duvall, his consciousness returning, insisted upon getting up from the
+couch, and going to work with equal determination. The way in which he
+had been checkmated, in the whole affair, roused him, as well, to
+desperation. His professional skill, upon which the banker had set such
+great store, seemed to have deserted him. He felt humiliated, ashamed.
+In three days, he had accomplished nothing whatever. It was galling in
+the extreme.
+
+Mr. Stapleton's explanations of his hallucination regarding his wife he
+accepted as true. The resemblance which Miss Goncourt bore to Grace,
+together with his constant thoughts of her, were, he argued, no doubt
+responsible for it. The blow upon the head made his recollections of the
+moments immediately preceding and following the assault extremely hazy.
+He put the matter out of his mind, and set to work with renewed energy.
+
+So far, it seemed, he had met with but a single clue of any
+importance,--the cigarette with the gold tip which he had found in the
+Bois de Boulogne. He determined to follow this clue until he arrived at
+some definite result.
+
+As soon as the doctor had departed after dressing the wound in his head,
+Duvall took a stiff drink of brandy, and, sitting down with Mr.
+Stapleton at the latter's desk, began to reconstruct, as far as he
+could, all the details of the kidnapping. He spoke his thoughts aloud,
+taking Mr. Stapleton into his confidence, since in this way he could
+most readily get his ideas into concrete form.
+
+"Mr. Stapleton, I am, I confess, greatly humiliated at the progress, or
+lack of progress, which I have made in this case so far. I have made up
+my mind, however, to get these fellows, if it takes me the rest of the
+summer."
+
+"You will have to work more quickly than that, Mr. Duvall," observed the
+banker coldly. "I have made arrangements to recover my child by tomorrow
+night."
+
+"You are going to buy these rascals off, then?"
+
+"Yes."
+
+"How?"
+
+"I decline to say. I've had enough interference with my plans already.
+Neither you nor the police have accomplished anything. Miss Goncourt
+knows what I propose to do; but she has given me her word not to
+interfere. If you are to accomplish anything, it must be before eight
+o'clock tomorrow night."
+
+"Very well. I will make my plans accordingly."
+
+"What do you propose to do?"
+
+"That I cannot say, at the moment. I think, however, that I shall first
+try to find out who it is that smokes these gold-tipped cigarettes." He
+drew the fragment of cigarette which he had found from his pocket, and
+placing it on the desk before him regarded it critically.
+
+Mr. Stapleton gave a grunt. "What are they, Exquisites?"
+
+"Yes. How did you know?"
+
+The banker laughed. "Easy enough. My wife smokes them."
+
+The detective looked up quickly. "Indeed! Brings them from America with
+her, I suppose."
+
+"Yes."
+
+Duvall began mentally to check off, in his mind, the various persons who
+might have used the cigarette which lay before him. Valentin, he now
+believed, was out of the question. His presence in the automobile, with
+Grace, the night before, indicated that he had nothing to do with the
+kidnappers.
+
+There remained Mrs. Stapleton. Duvall had talked with her--seen her
+grief. He was too shrewd a judge of human nature to think for a moment
+that it was assumed.
+
+Who else? Suddenly an idea flashed into his mind. He wondered that he
+had not thought of it before. The nurse! He recalled vividly the marks
+he had observed on the dresser in the woman's room in New York.
+
+"Is Mary Lanahan in the house?" he inquired of Stapleton.
+
+"Yes. Why?"
+
+"Kindly have her come here."
+
+Mr. Stapleton pressed a button on his desk in silence. In a few moments,
+the nurse had been brought to the room by one of the other servants. She
+was haggard with grief and fear.
+
+Duvall requested her to be seated, and began to ask her a number of
+apparently unimportant questions regarding the kidnapping.
+
+She answered them frankly enough, although it was clear that she was
+very ill at ease.
+
+Presently Duvall got up, and, calling Mr. Stapleton to one side, asked
+him, in a low tone, to detain the nurse in the library for a few
+moments. He wished to search her room.
+
+"But it has already been thoroughly searched by the police."
+
+"I know. But I must search it again. It will require but a few moments."
+
+Stapleton nodded. "I will wait for you here, Mr. Duvall," he said.
+"Mary, you will wait, as well."
+
+The nurse's room was on the third floor, in a rear building. Duvall
+found it, after some slight difficulty, with the assistance of one of
+the other servants.
+
+He seemed, on entering the room, to have but one object in view. He went
+at once to the mantel, and, taking from it the two small bottle-shaped
+vases which stood upon it, shook them both vigorously. A faint rattling
+sound came from the second. He turned it upside down upon the palm of
+his hand, and there tumbled out a quantity of ashes, and the butts of
+several partly smoked cigarettes. With a quiet smile he replaced them in
+the vase, and returned to the library.
+
+"Mary, you may go now," he said.
+
+When the woman had gone, he turned to Mr. Stapleton. "It was Mary
+Lanahan herself who smoked the cigarette which I found in the grass," he
+said.
+
+"Well, what of it?" The matter seemed to the banker to be utterly
+without significance.
+
+"She had, no doubt, stolen them from Mrs. Stapleton."
+
+"Very likely. Not a very serious matter, however."
+
+"No. But the question now arises, Why did she turn the box over to
+Valentin, and subsequently ask him to destroy it?"
+
+"I cannot imagine."
+
+"And why, later, were these cigarettes stolen from Valentin, as I
+understand they were?"
+
+"It's too much for me. What do you make of it?"
+
+"I have a theory, Mr. Stapleton; but I cannot say just what it is--yet.
+By the way, where is your man, Francois, tonight?"
+
+"He is visiting his people, somewhere in the suburbs."
+
+"Ah! Then I would like to search his room, as well."
+
+"Go ahead. You will find nothing, I fear. The police have gone over it
+with a fine-tooth comb." He rose. "Come along, I'll go with you."
+
+The room occupied by the chauffeur was at the very top of the house,
+with two windows opening through the slanting mansard roof. One of
+these, Duvall noted, commanded a view over the houses adjoining toward
+the north, beyond which could be seen the Avenue du Bois de Boulogne. A
+second window, toward the south, commanded an extensive view toward
+Passy.
+
+Mr. Stapleton, puffing because of the unaccustomed stairs, sat down upon
+the bed. "I cannot imagine what you hope to find here, Duvall," he
+grumbled.
+
+The detective made no reply, but began a systematic inspection of the
+room. One of the first objects which attracted his attention was an
+ordinary electric searchlight, of the pocket variety, lying on the man's
+dresser. He picked it up, and examined it carefully.
+
+"I got it for Francois," observed Mr. Stapleton, "so that he could
+examine the car, at night, in case of any accident or repair."
+
+"Of course. Very useful, too. But why, I wonder, does he keep it here in
+his room, instead of in the garage?"
+
+"Possibly to light himself up the stairs, at night," said Stapleton.
+
+"Then I should think he would have it with him," remarked Duvall, dryly.
+"Wouldn't be of much use to him tonight, for instance." He was about to
+put the thing down, when his attention was attracted by two objects,
+hanging one on each side of the dresser, from its two uprights. They
+were apparently Christmas tree ornaments, made of thin glass, and they
+hung from the back of the dresser by means of two bits of ribbon.
+
+They seemed at first glance to be merely souvenirs of some party, some
+entertainment, which the chauffeur had preserved as mementos of the
+occasion. They were shaped like little cups, with a paper fringe about
+the top, to which the gay ribbons were attached. Duvall had seen such
+ornaments often before, at Christmas time. They were intended to be hung
+from the tree by their ribbons, and were filled with small candies or
+bonbons. He had almost passed them by, when something in their colors
+caused him to pause. One was a deep blue, the other an equally deep red.
+He examined the wooden uprights of the dresser with great care. All
+along the top of the dresser at its back was a heavy coating of dust.
+The top of the uprights, over which the loops of ribbon which supported
+the little baskets had been passed, contained no dust whatever.
+
+Evidently the baskets had been taken down, and that too quite recently.
+For what purpose? he wondered. Suddenly he had an inspiration. He took
+down the little blue basket, and quickly placed it over the end of the
+searchlight. It fitted perfectly, the paper collar at its top holding
+the glass hemisphere snugly in place.
+
+Mr. Stapleton was watching Duvall without particular interest. Suddenly
+the detective pointed the searchlight toward him and pressed the button
+which threw on the current. Mr. Stapleton started back, as his face was
+flooded with a beam of brilliant blue light.
+
+Duvall replaced the little basket in the same position in which he had
+found it, and laid the searchlight upon the dresser. "Rather neat, isn't
+it?" he exclaimed.
+
+"What do you make of it?" asked the banker.
+
+"Your man Francois evidently is in the habit of making signals," the
+detective replied, laughing. He was beginning to feel hopeful. The
+search of the two rooms was bearing fruit.
+
+For the next half-hour, Duvall went over the contents of the chauffeur's
+room with the utmost care. He removed and replaced, just as he found
+them, the contents of the dresser drawers. He opened a small wooden
+trunk which stood at one side of the room, and examined its contents
+minutely. He explored the closet, looked behind the pictures, sounded
+the walls. Nothing further of an unusual nature rewarded his efforts.
+Still he seemed unsatisfied.
+
+"What more can you hope to find, Mr. Duvall?" inquired the banker, who
+had begun to find the proceedings tiresome.
+
+The detective stood in the center of the room, and glanced about in some
+perplexity. "I had hoped to find one thing more," he said; "but I am
+afraid it isn't here."
+
+Suddenly he strode over to the mantel, upon which stood a small
+nickel-plated alarm clock of American make.
+
+"This clock doesn't seem to be going," he remarked, then whipped out his
+magnifying glass and carefully studied the brass handle which projected
+from the back, by which it was wound up. "It hasn't been wound for
+several days, either. The back is covered with dust." He picked up the
+clock and tried to wind it; but the handle resisted his efforts.
+
+In an instant he took out his knife, and a moment later was removing the
+screws which held the metal back of the clock in place.
+
+Mr. Stapleton watched him curiously. Duvall's methods savored, to him,
+of the accepted sleuth of fiction. He took little stock in the tiny
+clues upon which the whole modern science of criminology is built.
+
+In a few moments the detective had removed the screws and lifted out the
+rear plate of the clock. As he did so, he gave a grunt of satisfaction.
+A small pasteboard box fell out upon the mantel.
+
+"What is it?" asked Stapleton.
+
+"The box of cigarettes," remarked Duvall, as he opened it. "There are
+three missing. I shall take a fourth." He selected one of the
+paper-covered tubes, placed it within his pocketbook, then thrust the
+box back into the clock, and rapidly replaced the metal plate.
+
+"I don't think there is anything further to be done here, Mr.
+Stapleton," he remarked. "I think I'll be getting along to my room.
+Tomorrow I shall be quite busy."
+
+He stopped for a moment, on his way out, to glance from the window which
+faced toward the north. Between the buildings and trees ran the Avenue
+du Bois de Boulogne, its course illuminated by many street lamps, and
+the flashing lights of passing motor cars. Duvall gazed intently at the
+scene before him for a few moments, then turned to the door, and,
+accompanied by Mr. Stapleton, descended the stairs.
+
+As he was about to leave the house, the banker, who evidently had
+something on his mind, stopped him.
+
+"Mr. Duvall," he said, earnestly, "I would like very much to know what
+you intend to do."
+
+"I'm going to catch these fellows, if I possibly can," the detective
+replied, earnestly.
+
+"What steps do you propose to take?"
+
+"I cannot exactly say--yet. Why do you ask?"
+
+"I'll tell you. The fellow who was here tonight, the one with the black
+beard, is coming to see me tomorrow night, at eight o'clock. I cannot
+tell you more than that. I did not intend to tell you that much--but I
+am obliged to do so."
+
+"Obliged! Why?"
+
+"Because I want your promise that you will make no attempt to stop him.
+If I had said nothing, you might have watched the house, and, upon
+recognizing the fellow as the one who was here tonight, have placed him
+under arrest. I want you to do nothing to interfere with either his
+coming or his going. He will be safe, after he once leaves the Arc de
+Triomphe in his automobile."
+
+"But the police?"
+
+"They know nothing of the matter. Miss Goncourt has given me her word to
+remain silent. She has even agreed to have the men on watch about the
+house withdrawn. Both you and the police may do your best to catch this
+man, after I have carried out my compact with him; but until then I
+want you to keep your hands off."
+
+Duvall was silent for a moment. "Very well, Mr. Stapleton, I shall do as
+you say. In fact, to assure you that I am carrying out your wishes, I
+will agree to remain here with you, at the house, throughout the
+evening."
+
+"Good! I shall expect you. Good night."
+
+"Good night." Duvall left the house, and went at once to his hotel.
+
+Here, a few moments later, he seated himself in an easy chair, and
+taking from his pocket the cigarette which he had secured in the
+chauffeur's room, regarded it critically.
+
+After some little time, he took a match from a box upon a nearby table,
+and, placing the gold tip of the cigarette between his lips, carefully
+lit it.
+
+He drew the smoke into his lungs, inhaling it deeply. Once--twice--three
+times he repeated the operation, then threw himself back into his chair,
+and, closing his eyes, sat buried in thought. In his preoccupation, he
+allowed the end of the cigarette to fall unheeded to the floor.
+
+After many minutes he opened his eyes and started up. "I've got it!" he
+cried, and, picking up the half-burned cigarette from the floor, threw
+it carelessly into the fireplace.
+
+Then he sat down at his table, drew out a sheet of paper and a map of
+the city of Paris, and began to make a series of drawings and
+calculations that occupied him far into the night.
+
+
+
+
+CHAPTER XIII
+
+
+It was nearly ten o'clock when the taxicab containing Grace Duvall
+stopped alongside the road, at a point some four miles beyond the city,
+in the direction of Versailles. She had been unable to give the driver
+the exact location at which she desired to be put down, but had directed
+him to drive on until she told him to stop.
+
+The spot was quite familiar to her, owing to the hours she had spent in
+the vicinity with the searching party the day before.
+
+The taxicab driver seemed rather surprised to see her alight at this
+somewhat lonely spot; but he shrugged his shoulders with true Parisian
+indifference, pocketed the tip she gave him, and drove rapidly off in
+the darkness.
+
+Left to herself by the roadside, Grace began to fear that she had, after
+all, done a rather foolish thing. Now that she was here, she hardly knew
+how to begin.
+
+All about her she saw the dark outlines of cottages among the trees,
+with here and there a straggling light which betokened some household
+late in getting to bed. The country people in this vicinity--growers of
+flowers and vegetables or dairymen for the most part--were asleep with
+their cows about the time that Paris began to dine.
+
+Occasionally the silence about her was broken by the mournful howling of
+a dog; but otherwise all was still.
+
+The night was cloudless, and the lightening of the sky toward the east
+told her that before long a moon would rise above the trees.
+
+Near the road she found a little rustic bench, and upon this she sat
+down to think.
+
+The howling of the dog had suggested to her mind a possible clue to the
+house within which Mr. Stapleton's boy had been, for a time at least,
+confined. She could remember nothing of the garden, and but little of
+the room in which she had been confined; but the dog, playing upon the
+grass with the child, had fixed itself in her memory. She recollected
+distinctly that he was a poodle, mostly black, with fine curling hair,
+like astrakhan fur, and a pointed nose.
+
+There were many dogs of this sort, she well knew, and yet there was one
+peculiarity which had impressed itself upon her memory, which would
+inevitably serve to identify this particular dog, should she ever see
+him again. His long and bushy tail, black for the most part like the
+rest of his body, terminated in a plume of white hair.
+
+It was a most unusual marking in a French poodle. She had never seen it
+before, and she was a great lover of dogs, and knew them thoroughly. It
+was this fact, no doubt, which had caused her to notice the animal, at a
+time when her mind was filled with matters of vastly greater importance.
+
+She had sought carefully for such a dog, on the occasion of the previous
+search, but had not found him. The tale about the escaped cobra had
+caused the country folk to lock up their pets without loss of time.
+
+Now she hoped to find this dog, and through him discover the location of
+the house in which she had been confined. After that--well, she would do
+the best she could.
+
+It occurred to her that she was not at all likely to discover the
+whereabouts of the black poodle by sitting here on a bench; yet she
+dared not start out until the moon had risen sufficiently high to light
+up her way.
+
+In about an hour, the rim of the golden disk showed itself above the
+treetops, and a little later the black shadows about her began to grow
+luminous, and resolve themselves into white-walled cottages, hedges, and
+outbuildings of various sorts.
+
+A narrow lane ran off from the main road, bordered on each side by
+lindens and poplars.
+
+Along this lane the houses of the little hamlet were set, some near the
+road, others quite a distance back. She rose, and began to walk slowly
+along the lane.
+
+As she had expected, dogs of various sorts and sizes, to judge by their
+voices, began barking as soon as she came opposite the first house. A
+small fox terrier ran through the gateway of a garden, yelping sharply.
+The deep-toned baying of a hound sounded farther up the street. A small
+white poodle, and a black one of the same size, ran after her, as she
+went along, making friendly attempts to play. The one she sought,
+however, seemed nowhere in evidence.
+
+The lane ascended a gently sloping hill, at the top of which stood a
+house, somewhat larger than the others, whose outbuildings and pastures
+proclaimed it to be a dairy farm. There was a hedge of roses along the
+roadside, and a little wooden gate.
+
+Grace heard a sharp bark on the other side of the gate as she passed it,
+and, stopping, glanced over. In the shadow stood a black poodle; but
+whether his tail showed the markings for which she sought she was unable
+to tell on account of the darkness. She gave the gate a gentle push, and
+it slowly opened. The dog ran out into the road. As he crossed a patch
+of moonlight, she saw that her search was ended. This, she was
+convinced, was the dog--and the house!
+
+Her next problem was how to get inside. Try as she would, she could
+think of no excuse which would adequately account for her presence in
+this little frequented locality at such a time of night. That the
+occupants of the house had long ago retired was evidenced by the
+blackness of the windows, the silence which brooded over the whole
+place.
+
+She looked about her. Just across the lane from the little gate a
+building loomed formless against a shadowy clump of trees. She went
+over to it, and found that it was a small shed. The door stood open.
+Inside stood a tumbledown old wagon, dust covered, and quite evidently
+unused for a long time. The shelter of the shed seemed grateful--as
+though she had arrived somewhere, instead of being a wanderer in the
+night.
+
+There seemed nothing to do, now, but wait for daylight. She climbed into
+the creaking wagon and sat upon the seat. There was a back to it, which,
+like the seat, was covered with old and torn velveteen. She leaned back
+in the shadow and closed her eyes. Her walk, the night air, had made her
+tired. In the distance she heard, after a long time, the faint booming
+of a bell. She looked at her watch. It was midnight.
+
+The next thing that Grace remembered was the loud barking of a dog. She
+sat up, feeling stiff and cold. Her neck and left shoulder ached
+painfully. A glance through the open door of the shed told her that it
+was still night; but there was a gray radiance in the air, a soft pale
+light, that betokened the coming of dawn.
+
+She crept stiffly down from the wagon, and again consulted her watch. It
+marked the hour of four. Through a dusty window in the side of the shed
+she saw the eastern sky, rose streaked and bright, heralding the sun.
+
+As the light increased, she saw the dog that had disturbed her sleep
+running about on the grass in front of the house opposite. The house
+seemed much nearer, in the daylight, than it had appeared at night. She
+examined the dog closely. The white tip of his tail, waving gaily in the
+morning light, showed her that it was the one she had sought.
+
+She crouched in the dim shadow of the half-open door and watched the
+scene before her. There was a man, moving about among the small
+buildings to the right. She heard him performing some task--she could
+not at first make out what. Presently the lowing of cattle, the rattle
+of a bucket, as it was drawn up by a creaking windlass, told her that
+the man was tending his cows.
+
+Quite half an hour later she saw him going toward the house, a pail,
+evidently well filled, in each hand.
+
+Then ensued another long silence. The curling wisp of smoke from the
+chimney of the cottage indicated breakfast, and Grace suddenly realized
+that she felt cold, and hungry. For the first time in her life she
+realized how important one's breakfast is, in beginning the day.
+
+Presently the man reappeared and went toward a small building which
+Grace took to be the barn. She could see him clearly now; for the sun
+had risen above the trees and lit up the whole scene brilliantly. He was
+a small, wizened man, with gray hair and a slight stoop. She was quite
+certain that she had never seen him before.
+
+He went to the barn, and she saw that he was engaged in harnessing a
+horse, which he presently attached to a farm wagon. She noted the wagon
+particularly. It was a low two-wheeled affair, with a dingy canvas top.
+A large patch in the canvas showed yellow-white in the sunlight. The
+horse was white.
+
+In a little while the man began to put in the cart a variety of objects
+which he brought from the barn. They appeared to be baskets of
+vegetables or fruit, and cans of milk. Presently he stopped, and went
+toward the house. In a few minutes he returned. This time a woman was
+with him. They carried between them a large wicker basket, which
+appeared to be quite heavy. There was a top on the basket. Grace
+wondered if it could be filled with laundry.
+
+The couple placed the basket in the wagon, putting it in from the front,
+so that it occupied a position close beside the driver. In getting it up
+over the wheel the woman let her end of it slip, and the man cursed her
+with such sudden sharpness that Grace was startled and crouched back
+into the shed. She wondered what the basket could contain, that made the
+man so careful, and the thought came to her, might it not be Mr.
+Stapleton's boy?
+
+The idea possessed her completely. As the man drove out into the lane,
+and rattled down the hill toward the main road, she suddenly realized
+that she must follow; yet how could she hope to do so, on foot? The
+woman had gone back into the house. Regardless of consequences, Grace
+ran out into the lane, and after the wagon at full speed.
+
+When she reached the main road the vehicle had already turned into it
+and was some distance away, headed for Paris, at a speed which, slow for
+a horse, was still much faster than she could possibly walk.
+
+She looked up and down the road helplessly. There were several other
+wagons approaching, all going in the same direction--cityward. She
+realized that they were country people, farmers, taking their vegetables
+and flowers to the markets.
+
+The first one to reach her was driven by a buxom-looking young woman,
+wearing a plaid shawl. Grace hailed her. "Will you be so good, Madame,
+as to take me to Paris?"
+
+The woman glanced at her shrewdly. "I have a heavy load, Mademoiselle,"
+she replied. Her voice was cold, uninterested.
+
+"I will pay you five francs--"
+
+The words had barely left Grace's lips, before the woman had pulled up
+her horse. "Five francs, Mademoiselle? That is another matter. Get in."
+
+Grace clambered up beside the woman and glanced down the road ahead. The
+canvas-covered wagon was still in sight--mounting a hill some three or
+four hundred yards ahead.
+
+The woman looked at her curiously, noting her dress, her hands, her
+shoes. "You are not of the country, Mademoiselle," she remarked,
+pleasantly.
+
+"No. I belong in Paris." She turned to her companion. "I should like to
+return there as quickly as possible."
+
+"My Susette does not care to go above a walk," the woman remarked,
+gazing at her horse, plodding along with mechanical steps, as though
+utterly unconcerned as to whether or not they ever reached Paris. The
+wagon ahead was now out of sight, over the brow of the hill.
+
+"Would you like to make a louis?" Grace took a gold piece from her purse
+and held it in the sunlight. It glistened brightly.
+
+The woman drew back, regarding her companion suspiciously. "A louis? Who
+would not? What do you mean, Mademoiselle?"
+
+"There is a wagon ahead of us, a canvas-covered wagon, with a white
+horse. I am following it. If you will keep that wagon in sight until we
+get to Paris, I will give you this louis."
+
+She turned the gold piece about, making it sparkle in the sun. The woman
+glanced first at her face, then more carefully at the coin, then,
+reaching over, took it in her fingers, and raised it to her mouth. Grace
+wondered what she was about to do. In a moment she had sunk her teeth
+into it, then returned it to her companion. "It shall be as you say,
+Mademoiselle," she exclaimed as she pulled in the reins. "Allons,
+Susette!"
+
+The horse, evidently awakened from his morning dreams, started forward
+with a suddenness which almost precipitated Grace from her seat. The
+trees along the roadside began to fly past them. In ten minutes they
+were close behind the canvas-covered wagon, now moving along at a brisk
+pace.
+
+When they reached the fortifications, the two wagons were separated by
+not more than a dozen feet. Grace's companion glanced at her sharply.
+"From here I go to Grennelle, Mademoiselle," she exclaimed.
+
+Grace looked at the wagon ahead. "Follow it, please," she said. "I will
+give you another five francs."
+
+The woman obeyed in silence. The wagon in front of them headed off
+toward the northwest, going in the direction of Passy. Before a great
+while it crossed the Pont de Passy, turned into the Rue Nicolo, and came
+to a stop before a small brick house, standing in a little garden.
+
+Grace jumped down at the corner, after giving the woman the louis and
+the additional five francs. "Thank you," she said, and started slowly up
+the street.
+
+The wagon with the canvas cover stood quietly alongside the curb. The
+old man who drove it had approached the door of the house, and was
+ringing the bell.
+
+Presently one of the windows on the top floor was thrown open, and a
+man's head was thrust out. Grace could not see his face clearly. He
+looked down at the man at the door, who at the same time looked up. The
+window was instantly closed, and a few moments later the door of the
+house opened and the man came out.
+
+He stood talking with the driver in low tones for a few moments. Grace
+had walked on up the street, fearing to attract attention. Looking back,
+she saw that the two men were gazing after her. She dared not turn her
+head again, but at the next corner turned into a cross street. Then she
+stopped, and cautiously peered around the corner. The two men had gone
+to the wagon and were lifting out the large basket. A few moments later
+they disappeared with it into the house.
+
+After a time, the old man returned with the basket in his hands. From
+the way he carried it Grace could see that it was empty. He tossed it
+carelessly into the wagon, mounted the seat, and drove off.
+
+Grace looked at her watch. It was half past seven. She felt cold and
+hungry, and determined to get something to eat at once. A little pastry
+cook's shop and restaurant on the opposite side of the street attracted
+her attention, and she crossed over, entered, and ordered rolls and
+coffee. She could see the windows of the house into which the two men
+had carried the basket, from where she sat.
+
+She scarcely knew what to do next. It seemed almost certain that Mr.
+Stapleton's child was in the house across the way, and yet--it was
+merely an intuition, a guess, which might turn out to be entirely wrong.
+Yet she feared to go away, not knowing at what moment the child, if he
+was indeed there, might be taken elsewhere, and the clue hopelessly
+lost.
+
+She finished her rolls and coffee, taking as much time to consume them
+as she could. She had just made up her mind to go, when the door of the
+house across the street opened, and a man came out. He was dark, and
+heavily built, and dressed in the costume affected by artists. He headed
+directly for the pastry shop, and Grace realized that he was about to
+enter it.
+
+She turned her face away, fearing lest he might have noticed her, as she
+walked up the street. He did not even glance in her direction, however,
+but went at once to a counter at the rear of the place.
+
+The proprietor came up to him with a smile, rubbing his hands together
+cheerily. "Ah! Monsieur Durand. Up early this morning, I see. What can I
+do for you?"
+
+She did not catch the other's reply, nor did she dare to glance at his
+face. She shrank back into her corner, and, picking up a newspaper which
+lay in the window sill, began to read.
+
+The new customer remained but a few moments. When he left, Grace saw
+that he carried a large paper bag with him, which appeared to contain
+rolls or bread.
+
+He again entered the house, but this time remained inside but a few
+moments. A little later she left the shop, and watched him as he
+disappeared down the street.
+
+For half an hour she walked about, wondering whether she should
+telephone Monsieur Lefevre now, or wait until she had made certain that
+the whole affair was, after all, not a wild goose chase. Suddenly she
+was seized with a new determination. She went boldly up to the house,
+and rang the bell.
+
+In a few moments a sleepy-looking maid opened the door, eying Grace with
+lazy indifference.
+
+"I wish to see Monsieur Durand," the latter said.
+
+"He's out."
+
+"Then I must wait. I am a model. He instructed me to come at eight
+o'clock, and to wait until he returned."
+
+The girl shrugged her shoulders, and pointed to the stairs. "Top floor
+front," she grumbled, and turned away.
+
+Grace lost no time in getting up the stairs. To her surprise, the door
+of the studio, upon which was a card bearing Monsieur Durand's name, was
+unlocked. She pushed her way boldly in, and looked about. The room was
+scantily furnished, and contained little besides a couple of modeling
+stands, several large plaster figures and casts, two chairs, and a
+couch, evidently used as a bed. At the rear of the room was a closet.
+She turned to it and threw it open. It contained only an assortment of
+clothes.
+
+She felt completely baffled. There was no possible place, here, in which
+the child she was seeking could be hidden. Evidently she had been on
+the wrong track. And yet--what had the wicker basket contained?
+
+Suddenly she stopped, quivering with excitement. From somewhere in the
+room--she could not tell where--there came a low sobbing sound, as of a
+child, crying to itself. It vibrated throughout the room, at one moment
+close to her ears, the next far off, intangible, like a whispered echo.
+She stood, listening, every nerve tense with excitement, and still that
+low sobbing went on, coming from nowhere, evanescent as a dream.
+
+The thing seemed unreal, horrifying. She gazed about helpless. Then she
+heard the front door of the house suddenly slam, followed by the sound
+of heavy footsteps on the stairs.
+
+
+
+
+CHAPTER XIV.
+
+
+Richard Duvall rose, the following day, with a less troubled mind than
+at any time since his arrival in Paris.
+
+His calculations of the night before had brought him to a definite
+conclusion.
+
+After breakfasting in the cafe of the hotel he returned to his room, and
+rang up Monsieur Lefevre.
+
+"I want the assistance of one of your men, Monsieur," he said.
+
+"Ah!" laughed the Prefect. "You are--what you Americans call--up a tree,
+is it not?"
+
+"Not at all. You have said that there existed between us a competition,
+to recover Mr. Stapleton's child. I think I am going to win. But since I
+am not in a position to make the necessary arrests, myself, I am going
+to share the glory with you, my dear friend, by allowing one of your men
+to do so for me."
+
+"So you are confident?"
+
+"Reasonably so. Can you spare Vernet for the day? He is a good man."
+
+"One of my best. You shall have him. And if you succeed, I shall still
+regard myself the loser, and will buy the champagne, and the dinner at
+the Cafe Royale, as I agreed."
+
+"And I shall be most happy to do the same should I fail. Oblige me by
+requesting Vernet to come to my rooms at the hotel at once. Good by."
+
+Duvall hung up the receiver, and sat down with the drawings he had made
+before him. He awaited the coming of Vernet with impatience.
+
+The latter appeared in some twenty minutes.
+
+"What can I do for you, Monsieur Duvall?" he asked.
+
+"Good morning, Vernet. Sit down, and have a cigar. I have a little
+matter I wish to talk over with you."
+
+"Concerning the missing child of Monsieur Stapleton, I understand,"
+remarked Vernet, as he lit a cigar and drew his chair up to the table.
+He glanced at the drawings before him. "What are these, may I ask?"
+
+Duvall took up his pencil. "This, Vernet, is a map of a small part of
+Paris. Here, as you see, is the Avenue Kleber, terminating at the
+Champs Elysees just in front of the Arc de Triomphe."
+
+"I see. It is quite plain."
+
+"Here--this black square--is Mr. Stapleton's house. From there to the
+arch is a matter of some six hundred yards."
+
+"About that, I should say. What of it?"
+
+"Wait. The black-bearded fellow--the kidnapper--who visited Mr.
+Stapleton last night, and escaped by the ruse of being arrested by one
+of his confederates, will arrive at Mr. Stapleton's house at eight
+o'clock tonight."
+
+"Mon Dieu! If that is so, we have him!"
+
+"Not so fast. We shall not interfere with him--then."
+
+"But, Monsieur, would you let this fellow escape? It is my duty to
+arrest him, as soon as he puts in an appearance."
+
+"You are mistaken, Vernet. Your duty is to do as I instruct you.
+Monsieur Lefevre has placed you under my orders for the day."
+
+Vernet laughed. "That is so," he said. "What do you wish me to do?"
+
+"The man will come to Mr. Stapleton's house at eight o'clock, and will
+be given a large sum of money. He has agreed, if he is not interfered
+with, to have the address where the boy may be found telephoned to Mr.
+Stapleton within half an hour."
+
+"Ah! Then we shall follow, and get him after he has telephoned."
+
+Duvall laughed. "We are dealing with a far shrewder man than that,
+Vernet. This fellow will do no telephoning."
+
+"Then how will he let Monsieur Stapleton know?"
+
+"That is just what I am trying to find out. Put yourself in his place.
+He is known--he dare not remain in Paris--he gets five hundred thousand
+francs to give up the child. Is it not natural to suppose that he will
+leave the city at once?"
+
+"Yes. That is what I should do, in his place."
+
+"Of course. Now I understand that the fellow will walk from Mr.
+Stapleton's house to the Arc de Triomphe, a distance of six hundred
+yards. He can do that easily in ten minutes."
+
+"Yes."
+
+"Once at the arch, he will stand awaiting a fast automobile, which will
+come along the Champs Elysees. This automobile will stop for an instant
+and pick him up, then proceed at high speed along the Avenue du Bois de
+Boulogne."
+
+"Why do you think that?"
+
+"Because it will afford him the quickest and safest road out of Paris.
+From the arch to the Porte Dauphine is less than a mile. He can make it
+in five minutes. In fifteen minutes altogether then, he is outside the
+walls. In another fifteen minutes, he is beyond pursuit, in the
+country."
+
+"But you forget, Monsieur Duvall, that he has not yet advised his
+confederates that all is well, and that the address of the place where
+the boy is hidden is to be telephoned to Mr. Stapleton."
+
+"No, Vernet, I haven't forgotten that. In fact, I am coming to it now.
+Suppose you were in this fellow's place--how would you do it?"
+
+Vernet scratched his head thoughtfully. "He might fire a pistol from the
+car."
+
+"Too dangerous. The noise of the explosion would attract attention. He
+must work silently."
+
+"A wave of the hand, perhaps, to someone along the street."
+
+"Also dangerous. This fellow realizes that every possible step will be
+taken to capture not only himself, but his confederates. He anticipates,
+no doubt, that the road will be carefully watched. Why take chances,
+and run the risk of his confederates, at least, being arrested, when
+there are simpler, easier ways?"
+
+"Such as what?"
+
+"Do you not remember the signal, used on the Versailles road, the blue
+light?"
+
+"Ah! Exactly. He will signal to some one in a house along the way."
+
+"That would be easier and safer; but you will remember that there are no
+houses along the way--none, at least, in which a man of this sort could
+have a confederate hidden. But I should not say none. There is one,
+perhaps."
+
+"Indeed, Monsieur. And what house is that?"
+
+"Mr. Stapleton's. Look!" He drew toward him the sheet of paper. "Here,"
+he placed the point of his pencil upon the black square which indicated
+the location of the banker's residence, "is the house. The north window
+of a room on the top floor commands a view of the Avenue du Bois de
+Boulogne, from a point some 500 feet west of the Arc de Triomphe, to
+where it intersects the Avenue Malakoff. Beyond there, the view is
+interrupted. In fact, the trees along the Avenue du Bois de Boulogne are
+to some extent an obstruction; but at the crossing with the Avenue
+Malakoff there is a wide and uninterrupted view."
+
+"But a confederate in Monsieur Stapleton's own house?"
+
+"Yes. The chauffeur, Francois."
+
+"You astonish me, Monsieur. We have suspected the fellow, it is true.
+The very room of which you speak has been searched. We found nothing.
+How do you know that what you say is true?"
+
+"Never mind how I know it--now. The point is this--Francois, I fully
+believe, will be in that room, tonight, at eight o'clock, watching
+carefully the automobiles which pass the intersection of the Avenue
+Malakoff--"
+
+"Not necessarily, Monsieur. We can easily prevent it, by placing him
+under arrest."
+
+"That is exactly what we must _not_ do. Don't you see, it is absolutely
+necessary, for the recovery of Mr. Stapleton's child, that the signals
+go through uninterrupted?"
+
+"Of course, I had forgotten that. And these signals?"
+
+"Naturally I cannot tell--yet. I think, however, that the automobile for
+which Francois will be looking will show a brilliant blue light, while
+crossing the Avenue Malakoff. That is, of course, if our friend the
+kidnapper gets safely away, without being pursued."
+
+"And otherwise?"
+
+"I think the light would be red. He can make either, very simply, by
+means of a powerful electric searchlight--one of these pocket affairs,
+you know, fitted with colored glasses."
+
+"You interest me wonderfully, Monsieur Duvall. What next?"
+
+"It is, of course, most important that the signal given shall be the
+correct one. There must be no interference whatever with this fellow's
+escape--_up to that point_."
+
+"Ah--I begin to see. And what after that?"
+
+"First, let us continue with Francois. He will, I think, return a blue
+signal to the man in the automobile, to show that he has seen, and
+understood. He has the means to do so all ready, in his room."
+
+"And then?"
+
+"He will make, I think, a similar signal from his south window to some
+one who is on watch, in the direction of Passy. This second person, who
+no doubt has the child in his care, will then go to a telephone,
+transmit the address of the house where the child is hidden, to
+Mr. Stapleton, and quietly depart, to join his confederate
+in--say--Brussels. He will run not the slightest risk of capture. If, on
+the other hand, that message fails to go through, the address will _not_
+be telephoned, and the child will probably be killed."
+
+Vernet frowned grimly. "It is a remarkable plan, Monsieur. These fellows
+are no bunglers. I think, however, that we shall be able to stop them."
+
+"How?"
+
+"I will station myself at the Porte Dauphine with a fast automobile, a
+racer. When these fellows pass, I will follow them, and overtake them."
+
+"An excellent idea, Vernet; but how, may I ask, will you know the car,
+when it passes you? There are hundreds of cars on the Avenue du Bois de
+Boulogne, at eight o'clock in the evening."
+
+Vernet laughed. "I confess, Monsieur, you have me there."
+
+"Of course you might station a man at the intersection of the Avenue
+Malakoff and the Avenue du Bois de Boulogne; but I do not think he
+would be able to see the signal. By placing on the end of the
+searchlight a paper tube, the light would be invisible except in the
+direction in which it is pointed--and that, you will remember, is
+diagonally upward. A man on the sidewalk would not see it at all."
+
+"Then, Monsieur, I fail to see that there is anything we can do."
+
+"There is one thing, Vernet. You forget the answering signal, from the
+window."
+
+The Frenchman looked at his companion with undisguised admiration.
+"Sacre!" he exclaimed. "You have a mind, Monsieur Duvall, in a
+thousand."
+
+"Thanks," answered Duvall, dryly. "Now, my idea is, to have you select
+some point near the intersection of the two avenues, from which the
+window in the rear of Mr. Stapleton's house can be clearly seen. Station
+yourself there, tonight, with the fastest automobile you can secure. Let
+one man watch the window, another the vehicles passing in the Avenue du
+Bois de Boulogne. The moment you see the blue light, start after your
+man. He should be just across the intersection, on his way down the
+Avenue du Bois de Boulogne."
+
+Vernet rubbed his hands together with satisfaction. "We shall get
+him--never fear."
+
+"Of course," said Duvall, slowly, "all this is pure assumption on my
+part, based upon what I have discovered in the chauffeur's room. It may
+not turn out as I say, but the chances are fifty to one that it will."
+
+"And you, Monsieur? Where will you be?"
+
+"I shall be in the room, with Francois. I do not propose that _he_ shall
+escape. And further--I do not know that I am correct, in my assumption
+regarding his signals to Passy. He may go out, and send the telephone
+message himself. In that case, I shall follow. Or he may, through some
+unforeseen accident, get the wrong signal, in which case I propose to
+overpower him, and give the right one. Suppose we go, now, and take a
+look at the intersection of the Avenue Malakoff and the Avenue du Bois
+de Boulogne, and see what arrangements can best be made. Also, if Mr.
+Stapleton is out in his car, we may be able to take a few observations
+from his chauffeur's window." He took up his hat, lighted a cigar, and
+led the way to the door.
+
+They drove to the Arc de Triomphe in a cab, and, after dismissing it,
+walked slowly down the Avenue du Bois de Boulogne. At the intersection
+with the Avenue Malakoff they stopped and gazed about carefully,
+although in such a way as not to attract attention. A brief inspection
+served to confirm all that Duvall had said. It took them some little
+time to locate the window in the rear of Mr. Stapleton's house; but
+after a time they managed to do so, and saw that it commanded an
+uninterrupted view of the point where they stood.
+
+Vernet was highly satisfied, as they parted. It was deemed unnecessary
+for him to visit the chauffeur's room, and thereby run the risk of their
+being seen entering the banker's house together. Vernet departed to make
+his arrangements for the evening, strictly cautioned by his companion
+not to let Monsieur Lefevre into his secret. "It is a bet," he told
+Vernet. "I hope we shall succeed in winning it."
+
+After his companion had departed, Duvall dropped in to see Mr.
+Stapleton. He learned that the banker was out, driving in the Bois with
+Mrs. Stapleton, who, overcome by anxiety and grief, had great need of
+the fresh air to retain her health. She was fast breaking down under the
+strain.
+
+Duvall went up to have another look at the chauffeur's room. He had been
+unable to get a thoroughly clear idea of the view from the window, the
+night before, owing to the darkness.
+
+He found everything as he had left it,--the searchlight on the dresser,
+the colored glass ornaments hanging from their gay ribbons. The north
+window overlooked with perfect clearness the intersection of the two
+avenues, as he and Vernet had seen them from below. The other window
+presented a more distant view. Nearby roofs and chimneys obstructed it
+in part; but between them could be seen the villas and buildings in
+Passy, smiling in the sunlight. The sight impressed Duvall the more
+strongly with the cleverness of the men he sought to arrest. Somewhere
+in all that maze of buildings, that wide vista of houses and trees and
+distant fields, Mr. Stapleton's child lay concealed, and it needed but a
+flash of light from this window to set him free. Passing his fingers
+idly along the window sill, Duvall suddenly observed two parallel
+scratches in the white paint, which had apparently been made with the
+point of a knife. He knelt down, and sighted between them. His line of
+vision swept clear of the nearby roofs and chimneys, toward Passy.
+
+The detective turned from the window, a smile of satisfaction on his
+face, and proceeded to make a careful examination of the chauffeur's
+closet. It was here that he intended to lie hidden. He felt certain
+that, in order the better to perceive and send his signals, as well as
+to escape detection from below, the chauffeur would allow his room to
+remain unlighted.
+
+This, Duvall reasoned, would render it easy for him to lie concealed
+until the signal which would insure the safe return of the lost child
+had been given, after which he would call upon Francois with precision
+and despatch. Should anything occur to prevent the chauffeur from giving
+the favorable signal, he proposed to give it himself.
+
+The closet was close to the north window, and its door opened in such a
+way that Duvall saw at once that in the darkened room he could readily
+open it sufficiently to see all that Francois did, without running any
+serious risk of detection.
+
+He left the house at a little after noon and stopped in at a well known
+restaurant on the Boulevard des Italiens for lunch. He felt very well
+satisfied with the course that events were taking. If only he could get
+through with this thing, and get back to Grace, and the farm, he would
+be supremely happy. He became so absorbed in his thoughts that he failed
+to notice a gentleman who slipped quietly into the chair opposite him,
+until the latter leaned over and touched his arm.
+
+He looked up suddenly. It was Monsieur Lefevre!
+
+
+
+
+CHAPTER XV
+
+
+The few seconds that elapsed while Grace Duvall stood in the deserted
+studio in Passy, waiting for the arrival of the person who was ascending
+the stairs, seemed like eternities, so crowded were they with terror.
+
+What should she do--what, indeed, could she do? A dozen plans raced
+madly through her brain, confusing her, baffling her with their
+futility.
+
+That the missing boy was within the sound of her voice, she knew; for
+even as she stood trembling at the ominous footsteps on the creaking
+stairs, she could hear the low troubled childish moaning, coming
+apparently from the very air in front of her, yet affording not the
+slightest clue as to the boy's whereabouts.
+
+She glanced about the room in desperation. Nearer and nearer came the
+creaking footfalls on the stairs. She dared not leave the room now, and
+thereby meet the approaching man face to face on the landing; yet to
+remain where she was would result only in her being obliged to make some
+lame and halting excuse for her presence, and go, as soon as the man
+entered the room.
+
+Even this she could not count upon. The fellow, no doubt a desperate and
+unscrupulous ruffian, might attack her, might detain her a prisoner
+until the child had been safely removed to another place, beyond all
+hope of discovery. All the work of the past twelve hours would come to
+nothing. And even should he let her go, in safety, he could not fail to
+suspect the reasons for her presence and warn his companions.
+
+Clearly the only thing to do was to remain in the room, in hiding. There
+was but one place in which she could hope to escape instant
+detection--the closet. Yet even this promised but temporary safety; the
+man would be almost certain to open it, for some reason or other, and
+discover her presence.
+
+It was her only chance, however, and she took it. Even as the footsteps
+of the approaching man sounded upon the landing outside, Grace flew
+across the room and into the closet, closing the door softly behind her.
+In her haste, one arm of a velveteen coat which hung upon a hook,
+became jammed in the door, with the result that it would not entirely
+close. She realized that it was too late to remedy the trouble now, and
+crouched back trembling with excitement.
+
+The jamming of the door had caused it to remain slightly open, with a
+space half an inch broad between it and the casing. Through this, Grace
+could see a part of the room before her. She watched the door to the
+hallway intently, as it was thrown open.
+
+The man she had seen in the pastry shop came in, several packages in his
+hands. These he placed upon a table, and at once began to prepare
+breakfast. A small alcohol lamp served for coffee, and butter, rolls,
+and fruit he produced from the paper bags before him. There was also a
+bottle of milk. Grace wondered if this was intended for the child.
+
+The man went about his preparations silently. Grace occasionally
+obtained a good view of his face. He was apparently about thirty years
+of age, dark and swarthy. There was something familiar about his manner,
+his general appearance; although what it was, she could not tell. She
+was certain, however, that she had seen him before.
+
+Once or twice he made a move, as though to approach the closet; but
+each time it was something else that claimed his attention. Once it was
+to get a package of cigarettes that lay upon one of the modeling stands.
+Grace wondered what she would have done, had he kept on toward her, and
+opened the closet door.
+
+She fell to thinking, in momentary snatches, about home, and Richard.
+How curious it seemed for them both to be here in Paris, separated for
+all these days, yet so near each other! She wondered if Richard had
+written to her, and what he would think, not to have heard from her.
+Then she remembered that after all he had been in Paris but a few
+days--there was scarcely time for a letter to have reached him. She
+thought of Uncle Abe, pottering about among the flower beds, of Aunt
+Lucy grumbling good naturedly over her wash tubs, of Rose, singing her
+queer camp meeting songs in the spring twilight, of Don, and the other
+dogs, the chickens, and her beloved flowers, and wondered how all of
+them were getting along with Richard and herself both away.
+
+Her reveries were interrupted by a sudden sound which made her start
+forward, tense with excitement. The man in the studio had gone for a
+moment beyond the line of her vision, into a corner of the room to her
+left. She could not see what he was doing there, and it was while
+waiting for him to reappear that she had fallen into her day dream.
+
+The sound which startled her was the voice of a child, not crying, this
+time, but speaking clearly and distinctly. "I want to go home!" it said,
+in a high nervous voice. "I want to see my mamma!"
+
+The man answered roughly, impatiently. "You can't go now. Be quiet and
+come and eat your breakfast."
+
+He appeared suddenly in the line of view commanded by the crack in the
+door, and Grace saw that he held a small boy by one hand, and was
+leading him to the table. Here he placed him in a chair and set before
+him a glass of milk and a roll. "Hurry up now!" the man growled. "Eat
+your breakfast. I've got to go out."
+
+The man's words set Grace's heart to beating with renewed quickness. If
+the man was going out, she would be able to escape, and take the boy
+with her.
+
+She did not doubt that he was Mr. Stapleton's child. The girl's dress
+which he had worn on the former occasion had been removed, and in place
+of it he wore a suit of dark blue, somewhat dirty and worn. His face
+still appeared to be very dark, and his hair, which had formerly been
+long and curly, was cropped close to his head. He appeared to be well,
+but very nervous. Grace watched him eagerly as he devoured the roll and
+milk.
+
+When he had finished, the man took him by the hand and again led him to
+the corner of the room beyond Grace's sight. She strained her face
+against the opening in the door, striving in vain to see what he was
+doing; but it was useless.
+
+She heard the boy begin to object, begging the man in a querulous voice
+to let him go out and play. His captor, however, silenced him with a
+sharp word, accompanied by a blow. "Get in there, and keep quiet!" Grace
+heard him say, and after that all was silent. A moment later the man
+reappeared, put on his hat, and, going out, locked the door carefully
+behind him. Grace wondered if the maid had told him of her call, and
+thereby roused his suspicions.
+
+She waited until she heard the front door close, and then, emerging
+quickly from the closet, went toward the side of the room to which the
+man had gone with the child.
+
+At first sight, there appeared to be no place where the latter could
+have been hidden. The two walls were of gray-tinted plaster, cracked and
+stained with age. There was a rickety chair and a battered plaster
+figure of a centaur, against which leaned an easel and a mass of
+sketches, covered with cobwebs and dust.
+
+With extreme care, she examined the walls and floor. It seemed most
+likely that some trapdoor existed, affording an entrance to a secret
+closet in which the boy had been placed. A few moments' effort showed no
+traces whatever of such a hiding place. The floor was of planks, covered
+with dust, and the cracks between the boards were filled with dirt and
+showed nowhere evidences of having been recently moved. The walls she
+sounded gently with the handle of a modeling tool which she snatched up
+from the table; but they gave forth a uniformly solid sound.
+
+She stood, surveying the place in perplexity. Then a sudden thought
+occurred to her. The ceiling! It swept low down, at the corner of the
+room, and above it she knew there must be an attic. She went over and
+began to examine the dusty plaster surface with minute care.
+
+A sound of footsteps upon the stairs sent her scurrying back into the
+closet. She wondered why the man had returned so soon. Greatly to her
+surprise, she saw, as soon as the door opened, that the newcomer was not
+the one who had left her a short time before, but an older man, more
+heavily built. As he turned and glanced toward the side of the room
+where she was hidden, she saw that he wore a heavy black beard. It was
+the kidnapper himself--the man whom she had seen at Mr. Stapleton's
+house the night before!
+
+He appeared to be annoyed, at not finding anyone in the studio, and
+after a moment sat down and lighting a cigar, began to read a newspaper
+which he drew from his pocket.
+
+Grace watched him intently, hardly daring to breathe for fear he might
+hear her. An hour passed, and the air in the closet became close and
+hot. She felt so nervous that she could have screamed, when the door of
+the room suddenly opened and Durand appeared.
+
+The two greeted each other with a nod. "Where have you been?" the older
+man demanded, somewhat angrily.
+
+"I had to get a new battery." He took a short black cylinder from his
+pocket and laid it on the table.
+
+"Is the boy here?"
+
+"Yes."
+
+"Good! Now listen to your instructions." He lowered his voice, glancing
+swiftly toward the closed door of the room. "At eight o'clock I shall go
+to the banker's house and get the money. At eight fifteen, or a little
+before, Francois will get his signal and repeat to you. If he flashes
+the blue light, you will release the boy, leave the room, lock the door,
+and go at once to the Place du Trocadero. From the little tobacco shop
+you will telephone the address of this place--No. 42, isn't it?--to
+Monsieur Stapleton. That will be about half past eight. Do not telephone
+before that. Then wait for me in front of the shop. Do you understand?"
+
+"Perfectly. And if I get the red signal?"
+
+"In that event, do not release the boy, but lock the door and come to
+the tobacco shop, as before. I will communicate with you there. Old
+Martelle is perfectly safe. But I do not think there will be any
+trouble. You will get the blue light."
+
+"You seem sure."
+
+"I am. This man Stapleton is not going to take any more chances. Once I
+am in the automobile, I am safe."
+
+"They could arrest you while you are walking to the Arc de Triomphe,
+after leaving the house."
+
+"That is true; but what would they gain. They would not get the boy,
+would they? And they have no evidence to show that I stole him. Further,
+Francois reports this morning that he overheard Stapleton and his wife
+talking. There is to be no interference--at least not until I get away
+in the machine. They will follow me, of course. I fully expect it. But
+you know the steps I have taken to take care of _that_ game." He laughed
+grimly. "No--no--the thing is absolutely safe. We will get away without
+the least trouble."
+
+"Nevertheless, if anything goes wrong, and I do not get the red signal,
+what shall we do then?"
+
+"We'll talk that over, when the time comes. You meet me at Martelle's."
+
+"But suppose you can't be there? They might get you, you know."
+
+The man with the beard frowned darkly, and an evil expression came over
+his face. "If you get the red signal, and I do not meet you at
+Martelle's at half past eight, come back here, get the boy, and take him
+to Lavillac. And before you do so, cut off his left hand, and send it to
+Stapleton with a letter telling him that if I am not set free at once,
+you will send his head. That will bring them to terms."
+
+Grace shuddered as she heard the man's words.
+
+His companion nodded. "I understand," he said. "But I hope it won't be
+necessary."
+
+"It won't. They can't get me. I've planned too carefully. That American
+detective, Duvall, is a joke. He was out on the Boulevard du Bois de
+Boulogne this morning with one of the Prefect's men. They are figuring
+to have an automobile at the Avenue Malakoff and follow me." He laughed
+loudly. "Much good that will do them!"
+
+"How about Francois?"
+
+"Oh--in a week or two, after we are safely away, Francois will sprain
+his wrist, and be forced to give up his position as Monsieur Stapleton's
+chauffeur. He will join us in New York."
+
+The younger man puffed meditatively at his cigarette. "What's become of
+that woman Lefevre had snooping around? Seen anything of her, since
+last night?"
+
+"No. She hasn't been about. Not much danger of _her_ finding out
+anything."
+
+The other rubbed his chin, in deep thought. "She nearly got you, last
+night," he presently remarked.
+
+"Oh, no. Not a chance. I knew she was in the house, and I figured she
+would telephone to headquarters as soon as she learned who I was. All I
+had to do was to signal you, through the window, and the thing was done.
+Of course I didn't expect the Prefect's man to get there quite as soon
+as he did; but you handled him all right." As he spoke, the man rose,
+went to a small mirror that hung on the wall, and carefully removed the
+black beard which was so distinguishing a feature of his appearance.
+
+"Pretty hot, this thing," he announced, as he threw it on the table.
+"Got anything to drink about? I'm thirsty."
+
+Grace saw, as he turned toward her, that he bore a striking resemblance
+to the masked man who had given her the first message to Mr. Stapleton,
+in the room of the house on the road to Versailles. She trembled as she
+heard him ask for the drink. Suppose the bottle should be in the
+closet? She shrunk back in terror as the younger man rose and started
+toward her.
+
+Her alarm was needless, however. The fellow drew open one of the drawers
+of a small dresser that stood on the opposite side of the room, and took
+out a light green bottle. "Absinthe?" he inquired.
+
+"All right. One won't do any harm. Don't take any more, though." He
+began to pour out the drink into a glass which stood upon the table.
+"When you get the signal from Francois," he went on, "you are to answer
+it, as usual, so he'll know you've seen him. He doesn't want to stay in
+his room very long--for fear he might be missed."
+
+"They suspect him, of course."
+
+"Yes. He's being watched right along; when he's out of the house, that
+is. They've searched his room, and all that; but they haven't found
+anything." He chuckled, and began to sip his drink. "Nothing to find."
+
+The other man sat down at the table, and the two began talking over
+their plans of escape. Grace could not hear all they said; but, as
+nearly as she could gather, they intended, as soon as the younger man
+had joined the other, to run for Brussels in the automobile. Near the
+frontier they would leave the machine, change their disguises, and cross
+the frontier on foot. Once in Belgium, they seemed to think they would
+be quite safe.
+
+It was along toward noon when the older man readjusted his disguise and
+left the house. "I'm going to get something to eat," he announced. "I
+won't be back. You'd better not leave the place again. I'll send you in
+something, if you like." He glanced at the rolls and milk on the table.
+
+"It won't be necessary. I've got all I need. Guess I'll take a nap this
+afternoon. Well, good luck," he concluded, as the other started toward
+the door. "See you later."
+
+"All right." The black-bearded man passed noiselessly into the hall.
+"Don't sleep too long. Eight o'clock, remember." In a moment he was
+gone.
+
+Grace watched the other as he finished drinking his absinthe and lit a
+cigarette. Presently he went over to the cot and, throwing himself upon
+it, was soon snoring loudly.
+
+The long hot afternoon wore itself on. Grace leaned back against the
+wall of the closet, weak from the nervous tension of the situation. The
+place was hot and close. She felt faint from lack of air, from hunger.
+At times she dozed off, then recovered herself with a start, and stood
+trembling, fearful lest she had made some noise which might attract the
+attention of the sleeping man.
+
+After a time, the low complaining of the child began again, at first
+faint and seemingly far off, then growing in volume, until the tearful
+cries of "Let me out--let me out!" seemed to come from a point scarcely
+beyond the reach of her hand.
+
+The child's complaints at last awoke the sleeping man. With a muttered
+curse he rose, crossed the room, and disappeared from sight. Grace heard
+a low scraping sound, as of a panel being drawn back, and presently the
+man again appeared with the child, and again supplied him with bread and
+milk.
+
+After he had eaten, the man gave him a magazine with bright-colored
+pictures in it, to amuse him, and lay on the bed, smoking. The boy sat
+on the floor, looking at the book.
+
+Once or twice he tried to speak, but the man sharply bade him be quiet.
+About sundown, a step was heard on the stairs, and once again the boy
+was hastily placed in his hiding place, with threats of punishment if he
+cried.
+
+The new arrival was only a model, in search of work. The man spoke to
+her gruffly, and informed her that he had all the models he needed.
+After she left, he did not again release the child, but sat, reading,
+for a long time.
+
+At last he rose, took up the short black cylinder, which Grace saw was
+an electric searchlight, from the table, and went over and sat in the
+sill of the large double window which faced to the north. The window was
+open, and the room in darkness.
+
+Grace pushed the door of her closet open slightly, so as to get a better
+view. The window was directly opposite the closet, at the other end of
+the room. She could see the silent figure of the watcher, silhouetted
+blackly against the night sky without. Off to the north were many
+lights--the lights of the houses toward the Champs Elysees, and the Arc
+de Triomphe.
+
+For many minutes she watched, over the man's shoulder, waiting for the
+signal which would set both herself and Mr. Stapleton's boy free from
+their long confinement.
+
+Presently she heard the man utter a quick oath, and saw him peer out of
+the window, his figure tense and rigid, a pair of field glasses held to
+his eyes. In another moment he had dropped the glasses, picked up his
+electric searchlight, and flashed a signal into the darkness.
+
+It took him but a moment. In another he had rushed to the door, and
+Grace heard him turn the key in the lock and clatter down the stairs.
+
+She crept swiftly to the window and looked out. At first she could see
+nothing, but a confused maze of lights. In a moment she had seized the
+field glasses and was nervously sweeping the horizon. Suddenly she held
+them still for a moment, then drew back with a cry of dismay. Far off
+toward the Avenue Kleber there gleamed a light, high in the upper room
+of a house. It shone for a few moments, steady, baleful, full of unknown
+terror, then winked suddenly out and was gone. She dropped the field
+glasses upon the floor and staggered back against the table. _The light
+was red!_ She was locked in. The two men would undoubtedly be back in
+fifteen or twenty minutes. And then--she shuddered as she thought of
+what they intended to do to the kidnapped child. To herself she gave
+scarcely a thought. Then Richard's face came before her eyes, and she
+fell upon the window seat, sobbing bitterly.
+
+
+
+
+CHAPTER XVI
+
+
+When Monsieur Lefevre touched Richard Duvall on the shoulder, in the
+restaurant in the Boulevard des Italiens, he was filled with a very
+great feeling of anxiety, although he concealed it behind a mask of
+pleased surprise at the unexpected meeting.
+
+Since early the evening before he had had no word from Grace. He knew
+from Mr. Stapleton that she had left his house a short while after nine;
+but since then she had completely disappeared.
+
+The Prefect at first thought that she had been unable to keep her
+identity from her husband any longer, and had joined him. He later
+learned from Vernet that this was not the case. Now the old gentleman
+began to feel seriously alarmed at her continued absence.
+
+"How goes everything, my friend?" he asked, with an elaborate show of
+carelessness. "Have you found the kidnappers yet?"
+
+Duvall smiled. "Not yet. But I expect to have them, before the evening
+is over."
+
+"Indeed! I congratulate you. Have you seen anything of Mademoiselle
+Goncourt?"
+
+"No. Why?"
+
+"I thought perhaps you might have met her. You two are after the same
+game, you know."
+
+Duvall smiled grimly. "I don't believe she's following the same trail
+that I am," he said. "I expect to win that bet, Monsieur."
+
+The Prefect seemed a trifle uneasy. "The evening is not yet over,
+Monsieur," he replied. "But, in any event, I hope that Monsieur
+Stapleton's son will be returned to him without further delay, whoever
+brings about the result."
+
+"Come to his house tonight, Monsieur. I have arranged a little matter
+with Vernet which may surprise you. And then, too, we shall have to go
+and get the boy." He rose, and took up his hat. "We shall want you with
+us."
+
+"By all means. I shall be there, my friend. What hour would you
+suggest?"
+
+"Half past eight, at the latest."
+
+"Good! I shall be there at that time. Good day, _mon ami_."
+
+"Au revoir. Give my respects to Mademoiselle Goncourt." He left the
+restaurant and, going to his room at the hotel, proceeded to write a
+long letter to Grace. He reproached her for not having written to him.
+Here he had been in Paris four days, and had not heard a word from her!
+A letter, he felt, should have come by the very next steamer--several,
+in fact. He told her how greatly he missed her, how deeply he loved her,
+and how soon he hoped to return to her arms. And even as he wrote,
+Grace, half dead from fatigue, stood hidden in the closet at Passy, a
+mile away, watching with frightened eyes the kidnapper asleep on the
+pallet bed.
+
+Duvall had arranged to be at Mr. Stapleton's house a little before eight
+that night, and it still lacked twenty minutes of the hour when he
+ascended the steps of the banker's residence and was ushered into the
+library.
+
+Mr. Stapleton sat in grim silence, awaiting the coming of his visitor.
+He did not seem particularly glad to see Duvall. The latter's apparent
+failure to make any headway in the matter of recovering his missing boy
+had caused the banker to lose confidence in his abilities.
+
+"Good evening, Duvall," he remarked, indifferently.
+
+"Good evening, Mr. Stapleton. You are ready for your man, I see." He
+glanced at the package of banknotes which lay at the banker's elbow.
+
+"Quite. You have done nothing to interfere with his coming or going, I
+trust."
+
+"Nothing."
+
+Stapleton glanced at the clock. "He will be here very soon, now. May I
+ask you to wait in my study, upstairs? It would never do for you to be
+here. The man might be afraid to enter."
+
+"No--you are right. I must not be here. But I prefer not to wait in the
+study. I have another plan."
+
+"What is it?" inquired the banker, uneasily.
+
+"Where is Francois, your chauffeur?"
+
+"At his dinner, I believe. Why?"
+
+"Will you kindly find out for sure? I want to go to his room."
+
+Mr. Stapleton summoned a servant, who told him that the chauffeur was
+just finishing his dinner. "You will be very careful, Duvall," he said,
+anxiously. "I don't want anything done which will alarm these fellows."
+
+"Oh, Francois won't see me. I shall keep out of his sight. Perhaps I had
+better go up now." He nodded to the banker, and at once ascended the
+stairs which lead to the servants' quarters.
+
+At the door of the chauffeur's room he paused. It was closed. He pushed
+it gently open, and in a moment was in the room. The place was quite
+dark; but by means of a pocket light Duvall soon found the closet, and a
+moment later was safely ensconced within. He left the door ajar, and to
+his satisfaction found that he could see through the north window
+without difficulty. Here he waited, until the chauffeur should arrive.
+
+Mr. Stapleton, meanwhile, sat grimly in the library below, waiting for
+the coming of the kidnapper. Promptly at eight o'clock, his butler
+announced that the man had arrived.
+
+"Show him in at once," exclaimed the banker, as he rose and began to
+walk up and down the room.
+
+In a moment the man came into the library. His powerful figure, his
+black beard, his assured manner, rendered him an easily recognized
+figure.
+
+"I have come, Monsieur, as I said I would," he remarked, calmly. "I
+trust you have the money in readiness."
+
+Stapleton stepped over to the desk and picked up the package of
+banknotes. "Here it is," he growled. "I understand that you will, in
+return for this money, send me word at once as to where my son is to be
+found."
+
+"Within half an hour, Monsieur, at the latest; provided, of course, I am
+not interfered with in my escape."
+
+"There will be no interference, until I get back my boy. After that, I
+shall spend another hundred thousand dollars, if need be, to bring you
+to justice."
+
+"That, Monsieur, is quite within the terms of our agreement. The moment
+you receive the address, you are free from any obligation to me. May I
+see the money?" He extended his hand.
+
+Mr. Stapleton placed the banknotes in it. "Count them," he growled, "and
+assure yourself that you have received the amount you demand."
+
+The kidnapper sat down with the utmost coolness and began to count over
+the notes. They were all of large denomination, and the operation
+consumed but a few moments. As soon as he had finished, the man placed
+the bundle of notes carefully in an inside pocket and rose. "The amount
+is correct, Monsieur," he said. "Permit me to bid you a very good
+evening." Without further delay, he bowed, took up his hat, and left
+the room.
+
+At the door he glanced quickly at his watch, then strode off up the
+street at a rapid pace, toward the Arc de Triomphe.
+
+For some eight or ten minutes he walked, at the expiration of which time
+he arrived at the Place de l'Etoile, and at once crossed to the pavement
+surrounding the great triumphal arch.
+
+Up and down the twelve great avenues which radiate from the Place of the
+Star flashed innumerable automobiles, coming and going like huge jeweled
+fireflies.
+
+The kidnapper paused at a point on the very outer edge of the circular
+pavement which surrounds the arch, and waited, expectant, his eyes fixed
+upon the broad sweep of the Champs Elysees.
+
+For some moments he stood thus, rigid, motionless. Suddenly a big black
+racing car swept from the line of traffic and approached the curb. The
+man on the sidewalk raised his hand, and made a momentary gesture. The
+car quivered to the side of the street, pausing but the fraction of a
+second as the tall figure of the kidnapper stepped in. Another moment,
+and it had swept around the great arch and was flying down the Avenue du
+Bois de Boulogne.
+
+Close behind it came a second car, which, like the first, contained but
+a single occupant in addition to the chauffeur. With scarcely fifty feet
+between them, the two machines swept down the broad street toward the
+intersection with the Avenue Malakoff.
+
+In a few moments, both had reached it. But here their ways parted. The
+first car, turning in a quick and dangerous quadrant, swept into the
+Avenue Malakoff and sped southward like the wind. The second car
+continued on toward the Porte Dauphine. As it passed the intersection
+with the Avenue Malakoff, the chauffeur, unobserved by his passenger,
+directed a cylindrical black object toward the southern sky and held it
+there, motionless, until his car had disappeared in the shadow of the
+trees to the west.
+
+Just inside the Avenue Malakoff lay a third car, its powerful engine
+shaking it from end to end with its rapid pulsations. Two men sat in the
+tonneau. One of them was occupied in watching a distant window in the
+rear of a house on the Avenue Kleber with a pair of field glasses. The
+other kept his gaze fixed upon the road before him.
+
+Suddenly the man with the field glasses turned, and pointed toward the
+car which was just passing from sight along the Avenue du Bois de
+Boulogne. "Quick!" he muttered. "After him!"
+
+The automobile shot forward like a racehorse under the whip, and in a
+moment was flying down the avenue in hot pursuit.
+
+The foremost car was making high speed; but the one which pursued it was
+clearly the faster of the two. Slowly the space which separated them
+began to decrease. The man in the first car spoke quietly to his
+chauffeur, and the great car jumped forward with renewed speed.
+
+Vernet, in charge of the pursuing car, swore softly to himself as he saw
+his quarry pull away from him. He had confidence, however, in the speed
+of his own machine, and urged his driver to greater efforts.
+
+For several miles the two swept on, the rear car gaining slowly, in
+spite of the other's best efforts. They had passed the fortifications
+and were now in the Bois de Boulogne, and with clearer roads ahead the
+chase seemed likely to be a long one.
+
+Suddenly, to Vernet's astonishment, the forward car began to slow up. In
+a moment the Prefect's men ranged alongside, and covered the solitary
+passenger with their revolvers.
+
+"Surrender!" Vernet cried. "You are my prisoner."
+
+The man in the other car looked up, and calmly began to light a
+cigarette. "Are you a bandit, my friend?" he inquired, calmly.
+
+The detective was taken aback. The two cars had now come to a standstill
+at one side of the road. "Search him!" he said quickly to his companion.
+
+The second man climbed into the car. Its occupant made no protest. "What
+do you wish with me, gentlemen?" he asked, with a sarcastic smile. "My
+watch--my money?"
+
+"The searchlight, first of all," replied the detective, "with which you
+signaled."
+
+The man looked at him in astonishment. "What are you talking about,
+Monsieur?" he inquired. "Is this then a joke?"
+
+Vernet began to feel a trifle uneasy. This man certainly did not appear
+to resemble in any way the prisoner he had sought. He was a clean-shaven
+young man, elegantly dressed, and quite evidently a gentleman. "Do you
+deny," asked the detective, "that on passing the Avenue Malakoff a few
+moments ago you flashed a blue light toward the Avenue Kleber?"
+
+The young man laughed. "Of course I deny it," he said. "Why the devil
+should I be flashing blue lights at the Avenue Kleber? And who are you,
+to ask me any such nonsensical questions?"
+
+"I am an agent of the police, Monsieur. Who are you?"
+
+"I am Anton Lemaitre, stock broker, of the firm of Lemaitre and
+Bossard." He handed a card to the dumbfounded Vernet. "I am trying a new
+automobile, which I think of purchasing. My chauffeur proposed that we
+try it out in the Bois, where there is more opportunity to speed than in
+the city."
+
+"Why did you then run away?"
+
+"My dear sir, I saw you following me. I wish to own a fast car--the
+fastest car in Paris, if possible. I directed my driver to see what he
+could do. I do not believe, however, that I shall now buy the car, since
+yours is faster. What make is it, Monsieur, if I may ask?"
+
+Vernet smothered an oath. Clearly this man was telling the truth. He
+directed his companion to get in with Monsieur Lemaitre. "Drive to the
+Prefecture," he said, "and let the gentleman tell his story to Monsieur
+Lefevre." He himself ordered his chauffeur to proceed with all despatch
+to Mr. Stapleton's house. The affair had ended in a fiasco. He felt that
+he must see Duvall at once.
+
+In fifteen minutes he was at the house. Mr. Stapleton was waiting
+patiently in the library for the telephone call which would announce the
+hiding place of his boy. With him were Mrs. Stapleton and Monsieur
+Lefevre.
+
+The poor man and his wife were in a pitiable state, their eyes glued to
+the clock which stood on the mantel. It was marked twenty-six minutes
+past eight. "Only four minutes more!" gasped Mrs. Stapleton, through her
+tears. "My God! why don't they hurry?"
+
+Her husband endeavored to console her. "They may be a few moments late,
+my dear. Don't excite yourself. I am sure they will keep their word."
+
+Vernet went over to Monsieur Lefevre and explained the events of the
+evening in a few words. The Prefect smiled grimly. "So Monsieur Duvall
+has failed again!" he remarked, in a low voice. "Mon Dieu! If we do not
+soon hear from Mademoiselle Goncourt, I shall begin to feel nervous
+myself."
+
+Slowly the hands of the clock crept around. As the half hour was
+reached, and the telephone bell remained silent, Mrs. Stapleton uttered
+a groan of despair, and sank upon the couch, weeping pitifully. Mr.
+Stapleton, watch in hand, paced up and down the room. "They have been
+interfered with," he stormed, "or they would have communicated with me
+before now!" He turned to Monsieur Lefevre. "You have done nothing, I
+hope, to again prevent me from recovering my son?"
+
+"Nothing, Monsieur."
+
+Mr. Stapleton waited another five minutes. It now wanted twenty minutes
+to nine. The telephone bell remained persistently silent. The banker
+closed his watch with a snap and thrust it into his pocket. His face was
+pale with rage and suffering. Drops of perspiration collected on his
+forehead. "The scoundrels!" he cried. "They have broken their word, and
+robbed me of a hundred thousand dollars in the bargain. I will give
+another hundred thousand to the man who will capture them, dead or
+alive, and find my boy!"
+
+There was a profound silence, broken only by the quick sobbing of Mrs.
+Stapleton. Neither Lefevre nor Vernet ventured to speak.
+
+Suddenly there arose sounds of a commotion among the servants gathered
+in the hall without. In their devotion to their employer they had
+collected there to welcome the lost boy. There were exclamations, cries
+of astonishment--and dismay.
+
+The occupants of the room turned in surprise toward the door. As they
+did so, Richard Duvall appeared in the doorway. He staggered, and with
+difficulty supported himself by clutching the side of the door. His face
+was covered with blood, his clothes torn and disheveled.
+
+He swayed a moment, unsteadily in the door.
+
+"What is it--what is wrong?" cried Stapleton, starting toward him.
+
+"The child is at 42 Rue Nicolo, Passy," gasped the detective, then fell
+heavily upon the library floor.
+
+
+
+
+CHAPTER XVII
+
+
+Richard Duvall, waiting with nervous impatience in the closet in
+Francois' room, at last heard a soft and guarded step upon the stairs.
+He drew back, his muscles tense, and gazed fixedly at the door.
+
+Although the room was dark, the glow of the street lamps from without,
+the faint light of the evening sky, sufficed, now that his eyes had
+become accustomed to the darkness, to enable him not only to recognize
+the chauffeur as he entered the room, but to follow his movements with
+little or no difficulty.
+
+The man seemed hurried. He groped his way to the dresser at the opposite
+side of the room, and felt about for the searchlight which Duvall knew
+lay within easy reach.
+
+Having secured it, he directed it for a brief moment upon his watch,
+noted the time, then, going to the door, opened it, and began to listen
+intently.
+
+The detective at once surmised that he was listening for the departure
+of his confederate, the man with the black beard.
+
+Presently the chauffeur drew back, closing the door with a grunt of
+satisfaction, and once more approached the dresser. Duvall concluded
+that he had gone to get the colored glasses by which he would be able to
+make the required signals.
+
+In a moment he returned to the window, and Duvall saw him place the two
+glass cups upon the sill, and lean out expectantly.
+
+It seemed a long time before he stirred. The detective, looking over his
+shoulder, found that his line of vision was interrupted so that he could
+not see the lights which flashed past the entrance of the Avenue
+Malakoff. He was forced to content himself with keeping a close watch
+upon the chauffeur.
+
+Suddenly the man, by an almost instantaneous movement, clapped one of
+the little glass cups over the end of the tube which formed the
+searchlight, and directed it toward the street. Duvall could not tell
+whether the signal was blue, or red. He had every reason to believe,
+however, that it was the former.
+
+The chauffeur held the tube upon the window sill for a few seconds
+only, then withdrew it, and started to cross the room toward the south
+window. As he did so, he swept the light into the room, and for an
+instant it fell upon the crack in the closet door through which Duvall
+was peering. He was conscious of a blinding blue radiance, close to his
+eyes, and the sudden flash caused him to draw back with a quick and
+involuntary movement. He realized that the chauffeur had not seen him,
+and that, in a few moments more, the signal would be given which would
+bring untold happiness to both Mr. Stapleton and his wife.
+
+The momentary recoil, however, was fatal to his plans. Although he moved
+his head but a fraction of an inch, the suddenness of the movement was
+sufficient to cause a metal coat hanger, which hung, empty, from a hook,
+to click sharply against its neighbor.
+
+The chauffeur spun around with the quickness of a cat, and, grasping the
+knob of the closet door, threw it open. In his hand he still clutched
+the tube of the searchlight.
+
+Duvall at the same moment reached for the revolver which lay in a side
+pocket of his coat. He realized instantly that, now that his presence
+had been discovered, the chauffeur would of course not send the signal
+to his confederates in Passy which would result in the telephoning of
+the address to Mr. Stapleton, but would on the contrary flash a red
+signal, which the detective fully believed would result in the child's
+death.
+
+It was imperative that this should be prevented. Duvall had determined
+to be present in the chauffeur's room for two reasons,--first, to send
+the favorable signal to Passy himself, should things go wrong, and the
+chauffeur receive a red flash from the street; secondly, to arrest
+Francois in the act of receiving and sending the signals.
+
+He now realized that he must do both, and that, too, without a moment's
+delay.
+
+As the chauffeur threw open the door he flashed the blue light full upon
+the crouching figure of the detective.
+
+The latter, revolver in hand, commanded him sharply to throw up his
+hands.
+
+The chauffeur did so--thereby directing the light of the electric lamp
+toward the ceiling. The sudden change from the glare which an instant
+before had been in his eyes, to almost total darkness, left Duvall
+momentarily blind. His eyes could not instantaneously respond to the
+withdrawal of the light. The figure of the chauffeur appeared but a dark
+and formless shadow.
+
+The latter, however, not having faced the glare of the light, was able
+to see without difficulty. With lightning like quickness he spun around
+on one foot, until his back instead of his face was toward the
+detective. Then his right foot rose, in the famous and deadly blow of
+the _savate_.
+
+It has been said that this backward kick, so dear to the heart of the
+Parisian crook, is more to be feared than any possible onslaught in good
+old Anglo-Saxon style with the fists. Certainly in this instance it was
+too much for Richard Duvall. The unexpected blow, coming during the
+moment when the sudden darkness had left him blinded and confused, sent
+him crashing back into the depths of the closet, buried beneath a mass
+of clothing. His arms, entangled in falling coats and waistcoats, were
+helpless. The revolver flew from his hand, and lay useless on the floor.
+
+The chauffeur went about his business calmly. His first move was to
+direct the searchlight carefully into the interior of the closet,
+slipping the blue cup from the end of it as he did so and allowing it
+to fall unheeded to the floor. His second was to draw a long and
+peculiarly deadly looking knife.
+
+His quick eye saw at once that the revolver was no longer in the
+detective's grasp. His searchlight enabled him to discern it, lying on
+the floor to one side of the closet. Before Duvall could extricate
+himself from the articles of clothing in which he was entangled,
+Francois had stooped quickly, picked up the revolver, and slammed the
+door of the closet upon him. As he struggled to his feet, the detective
+heard the click of the key as it turned in the lock. He was a prisoner.
+
+Without losing a moment, the chauffeur tossed the revolver upon the
+table, took up the cup-shaped bit of red glass, fitted it to the tube of
+the searchlight, and, going to the south window, placed it upon the sill
+in such a way that its crimson glare was directed almost due south. It
+was evident that the position in which the light was placed was marked
+by the two tiny scratches cut in the woodwork of the window sill. In a
+moment he had turned back toward the closet door.
+
+Duvall, meanwhile, realized that only by instant and superhuman effort
+could he hope to remedy the frightful situation which his unlucky
+movement had precipitated.
+
+He braced his shoulders and back against the rear wall of the closet,
+put his two feet against the door, and with every atom of strength in
+his body strove to force it open.
+
+His movements had been quick. Just as the chauffeur turned back from the
+window toward the room, Duvall, his muscles knotted with effort, drove
+the full force of his body against the closet door.
+
+The lock, a cheap affair, was torn loose in a twinkling, and an instant
+later the two men had grappled in the center of the room.
+
+The detective's one desire was to get to the window, remove the red
+light which he knew was flashing its fateful message across the
+housetops, and substitute for it a blue light, which he hoped even now
+might shine forth in time to redeem the situation.
+
+This, however, the chauffeur was equally determined to prevent. He
+realized that he was caught, that his complicity in the affair was
+known, and that he must warn his comrades of his danger, so that, by
+refusing to give up the boy, they might effect his release. He was
+fighting for his liberty as desperately as Duvall was fighting for that
+of Mr. Stapleton's child.
+
+The two men were evenly matched. The chauffeur was perhaps the stronger,
+in shoulders and arms, due to his profession. The constant grip upon the
+steering wheel had given to his upper body muscles like steel.
+
+The detective, though somewhat less powerful in this direction, was
+stronger in the back and legs. He had been an athlete, at college, and
+his recent life upon the farm at home had toughened and hardened him
+from head to foot.
+
+He rushed at his opponent, threw his arms around the latter's waist, and
+strove to lift him and throw him to the floor.
+
+The chauffeur at the same time got his right arm about Duvall's throat,
+and with his left did his best to gouge out one of the latter's eyes.
+His was the style of fighting that considers not means, but results.
+
+For a moment they swayed heavily about the room, the detective burying
+his face in his opponent's side to protect his eyes, and at the same
+time striving with all his might to force him back toward the bed.
+
+Francois, however, fought well. He began to compress his adversary's
+throat in a choking grip of wrist and forearm which threatened to put an
+end to the struggle in short order. At the same time his left thumb
+continually sought the detective's eyes.
+
+Suddenly it reached one of them. Duvall felt a blinding sense of pain as
+the thumb nail sank into the soft and tender muscles about the eye. The
+shock was fatal to the plans of the chauffeur; for it raised up in his
+opponent a great and deadly rage, that for an instant gave him the
+strength of a madman. He raised his opponent from the floor as though
+the latter had been a child, broke the grip upon his throat by
+straightening his head, and with a mighty heave hurled him to the floor.
+
+The fellow struck upon his side, his temple crashing loudly against the
+wooden floor. Duvall stood over him for an instant, breathing heavily,
+convulsively, then turned and snatched the searchlight from the window
+sill and threw it upon the bed.
+
+There was a trunk against the wall of the room, near the window, and
+about it a broad leather strap. Duvall tore the strap from its place,
+and in a few moments had fastened it about the chauffeur's arms and
+body.
+
+A towel, knotted about his ankles, rendered him helpless. Then the
+detective began to search upon the floor for the bit of blue glass.
+
+In his heart there was no joy at the victory he had just won. He had
+captured one of the kidnappers, it was true; but on the other hand he
+had, by his own carelessness, prevented the safe return of the kidnapped
+boy to his parents.
+
+He pictured the father and mother, patiently waiting below for the
+telephone message which would never come, and wondered how he would dare
+to tell them the truth.
+
+At last his nervous fingers closed upon the little glass cup, where it
+had rolled under the edge of the dresser when Francois had thrown it
+down. Trembling with haste, he fixed it to the searchlight which he took
+from the bed, and, with a hopeless feeling, approached the window, and
+began to wave the light frantically in the direction of Passy.
+
+For several moments there was no response. As a matter of fact, he
+scarcely expected any. Then all of a sudden he saw a faint red gleam,
+like a star, flash from the distant night, and then go out.
+
+He stood, helpless, waiting for it to reappear, hardly daring to hope
+that it would do so. Suddenly it shone again, this time for a longer
+period, and then disappeared. He wondered what it meant, and was
+scarcely surprised when the light again flashed, this time making five
+quick flashes, which he instantly recognized as Morse code for the
+letter "P." There was a brief interval, then once more the signals began
+to flash. This time he read them without difficulty. There were four
+letters, spelling the word "Help."
+
+For an instant he leveled the tube of the searchlight toward the point
+from which the flashes came, guiding it by the scratches on the sill,
+and began pressing the button which turned the light on and off. "Where
+are you?" he spelled out, then waited fearfully for the reply. He dared
+send no other message. The person at the other end, the one who sent
+this ominous word, "help," must be one of the kidnappers; yet why should
+he signal for assistance? He could make nothing of the matter, but he
+reasoned that anyone calling for help would be sure to give their
+location, otherwise how could they expect to receive it.
+
+For a moment the red flashes began again, and this time he began to get
+the numbers. There were four quick flashes and a long dash, then others
+in rapid succession: "4-2-R-u-e-N-i-c-o-l-o, P-a-s-s-y," the message
+read. "C-o-m-e q-u-i-c-k."
+
+Duvall's head reeled, as he spelled out the words. He had not realized
+until now that he was wounded. The blood, pouring down his face from the
+great gash in his cheek, spattered thickly upon the window sill. He
+turned from the window, then realized that he must send some answer, to
+let this mysterious person at the other end of the line know that his
+message had been safely received.
+
+"Will come at once. Who are you?" he spelled out, laboriously, his head
+spinning, his fingers trembling from weakness as he tried to stop the
+flow of blood from his wound.
+
+"G-R-A-C-E D-U-V-A-L-L" came back the flashes, quick, clear cut,
+unmistakable.
+
+Duvall dropped the searchlight to the floor with a harsh laugh. His
+brain was reeling--the whole thing became a foolish, senseless
+nightmare. He wondered if he was delirious, and had dreamed it all.
+Again he flashed a signal into the darkness. "Who are you?" he spelled
+out again. He did not believe that he had read the former answer aright.
+Evidently his imagination was playing him tricks--Grace had been on his
+mind so constantly, throughout the day. He wiped the blood from his eyes
+and stared eagerly out into the darkness. There was no response.
+
+Then he remembered the words of the message, "Come quick." There was no
+time for idle speculations as to the identity of the person who had sent
+him the message.
+
+He rushed to the stairs, and with tottering footsteps descended to the
+library below. Francois, the chauffeur, still lay, bound and
+unconscious, upon the floor.
+
+
+
+
+CHAPTER XVIII
+
+
+For a few moments after being left alone in the studio at Passy, Grace
+almost lost her courage. She knew that the man who had remained on guard
+in the room had received the danger signal--the red light--which told
+him that the plans of his confederates had miscarried. She remembered
+the instructions which the black-bearded man had given him. "If I do not
+meet you at Martelle's, take the boy to Lavillac. And before you do so,
+cut off his left hand and send it to Mr. Stapleton."
+
+The very thought of the thing made her sick. She rushed to the door, and
+tore frantically at the knob; but it resisted all her efforts. She
+glanced at the windows, knowing that to escape by means of them from her
+position on the top floor of the house was impossible. And then--should
+she escape, she would be obliged to leave the child, and this she by no
+means wanted to do.
+
+Suddenly she heard again the faint moaning. The sound almost drove her
+frantic. She rushed to the window and looked out, praying for guidance,
+for some ray of hope in the frightful situation in which she found
+herself.
+
+Already several minutes had passed since the departure of the man. It
+would not be long, she felt, before he returned, and, for all she knew,
+the black-bearded man with him. Would they attack her, if they found her
+there? She could hide again, of course; but that would not accomplish
+anything, except perhaps, to save herself. And she had set out to rescue
+the child.
+
+In a whirl of indecision, she glanced out of the window, toward the
+point in the north where she had seen the red light. She wondered where
+it was, from what place it had been sent. Then suddenly, as she swept
+the horizon with eager eyes, she saw, where a few moments before the red
+light had flashed, a gleam of blue. Unlike the red signal, however,
+which had been steady, as though fixed in place, this one moved about
+restlessly, now pointing full at her, now almost disappearing to the
+right or left.
+
+She seized the field glasses and gazed at the light in wonder. Did this
+mean that the kidnappers had been successful, after all, and that the
+former signal had been a mistake, or did it indicate that the person
+giving the first signal had been overpowered, and that the light was in
+the hands of friends?
+
+She had no means of knowing; but here was someone who was trying to send
+her word that all was well. She determined to reply.
+
+Her one thought was to get to Mr. Stapleton her present address. She
+knew that the man who had been intrusted with the task of telephoning it
+to the banker, would not now do so. She would try to send the address
+herself.
+
+Then came to her a great feeling of joy, that she was familiar with the
+Morse code. Richard had taught it to her, during their trip from Paris
+to New York the year before. She remembered how she had been interested
+in the wireless, and Richard had offered to teach her the alphabet.
+
+She picked up the searchlight and examined it. It was an ordinary pocket
+lamp, with a dry battery, such as are sold at stores dealing in
+electrical goods, and she saw, from its size, that it was an unusually
+powerful one.
+
+Midway along one side was a tiny button, by pressing which the circuit
+was completed, and the light made to flash. By pressing this button
+momentarily, she could get a quick flash, comparable to a dot. By
+holding it down longer, she could produce a dash.
+
+She did not stop to remove the red glass which was fixed over the front
+of the light; in fact, she concluded that it would be better to let it
+remain. There were many white lights all about--among them, her own
+would have but a small chance of being seen. But red was significant,
+conspicuous, indicative of danger, and that she was in grave danger she
+very well knew.
+
+She decided to first send the word "help." She knew that if the person
+receiving the message was a friend, he would at once ask where she was,
+since that would be to Mr. Stapleton and his party the most essential
+and important news she could give.
+
+On the other hand, were it to be received by one of the kidnappers, he
+would ask her, not where she was, but what was the matter.
+
+Painfully, fearful of mistakes, she deciphered the message which slowly
+flashed across the mile of night. "Where are you."
+
+Illustration: With trembling fingers she spelled out her reply, giving
+the address and adding, "Come quick!"
+
+With trembling fingers, she spelled out her reply, giving the address
+and adding, "Come quick." When she got the answer, "Will come at once,"
+she felt that there was still a chance that the boy might be saved. Then
+came the request for her name. She gave this impatiently. What
+difference did it matter, so long as they came quickly.
+
+She hastily lighted a candle which stood upon the table, then cast about
+her for some means whereby she might prevent the black-bearded man and
+his companion from entering the room, in case they should return before
+help arrived. There was one thing, of course, that she could do,
+barricade the door.
+
+But, with the exception of the table and the light iron bed, there was
+nothing with which she could hope to secure it. Suddenly her eyes fell
+upon the great plaster centaur. It was a figure such as one might see in
+any art gallery or museum. It stood upon a plaster slab some six inches
+thick, which in turn rested upon a low wooden base. The figure was at
+least five feet high--a horse with a human torso and head. She knew that
+if she could jam this in front of the door, securing it in place with
+the bed and table, she might prevent the kidnappers from entering for
+some little time; long enough, she hoped, to insure the arrival of the
+police before they had succeeded in breaking in.
+
+She wondered if she could manage to move the thing. At first sight, it
+seemed impossible, and yet the base might by chance be fitted with
+rollers or casters. She rushed over to the figure and began to tug at it
+with all her strength.
+
+She needed but a moment to discover that she could not possibly move it;
+but as she bent over it, her head close to its side, she heard something
+which made her start with sudden joy.
+
+It was the low sobbing of a child--the same moaning sound which she had
+heard from time to time ever since she had first entered the room.
+
+At times the sound had appeared to come from afar off; at others, it had
+seemed to be close at hand, as though originating at some point in the
+very air about her.
+
+All of a sudden the truth came to her like a flash. The child was
+concealed within the hollow body of the statue. The thing seemed so
+simple, so apparent, that she wondered that it had not occurred to her
+before.
+
+She gave up her attempt to barricade the door, and began feverishly to
+look for the opening in the plaster cast through which the child must
+have entered.
+
+It took but a few moments to find it. The whole side of the horse's body
+had been sawed free, by two longitudinal cuts, one along the back, the
+other along the belly, and two similar cuts, at the shoulder, and the
+flank. Heavy strips of canvas, glued across the lower cut, on the under
+side of the horse's belly, served as hinges, and were not visible from
+above.
+
+She inserted the blade of a modeling tool which she caught up from the
+table, in the upper longitudinal cut, and pried the plaster side of the
+horse free. It fell heavily toward her, disclosing a long narrow
+opening; the interior, in fact, of the statue, where lay, upon a sort of
+bed made of an old comfort, the missing son of Mr. Stapleton.
+
+The boy, who had evidently until a moment before been asleep, gazed up
+at her in surprised alarm. For over two weeks, now, he had been kept
+from his parents, made to move about from place to place, frightened by
+strange men. He had come to expect the unusual, the terrifying, and it
+was a scared little face that looked appealingly up at the girl as she
+bent over him.
+
+For the time being she forgot the dangers which surrounded them, in her
+joy at the discovery of the boy. It had come so suddenly, so
+unexpectedly. If she could only escape, now, with the child, nothing
+else would matter in the least. And between her and freedom there lay
+but the thickness of a single door, and yet it seemed that she could not
+pass it.
+
+She lifted the child from his hiding place and stood him upon the floor,
+then quickly swung the heavy slab of plaster back into position. At
+least, she reasoned, the kidnappers, when they returned, should not at
+once learn that their captive had escaped.
+
+She knew that the hiding place had been but a temporary one, a means
+whereby the child might be kept out of sight during the day in case
+strangers should happen to enter the room. As soon as the kidnappers
+returned, they would, she realized, spirit the child away to some more
+secure retreat.
+
+She went to the door and again shook it frantically, pulling at the knob
+with all her strength, without producing the slightest result. The lock
+was evidently a strong one--the door held firm and unyielding, though
+she threw against it her entire weight.
+
+Evidently there was no hope of escape here. Then she again bethought
+herself of the window. For a moment she gazed out into the darkness. The
+pavement was thirty feet below. No one was in sight. How could she ever
+reach the ground, with the child as well, even if she had possessed a
+rope? The thing was impossible.
+
+Clearly there was nothing to do but wait. Possibly the assistance she
+expected from her friends, or the police, would arrive very soon--surely
+she could in some way keep the kidnappers occupied until then!
+
+And suddenly she realized that the time had come. She heard the door of
+the house close softly, and upon the stair the sound of mounting
+footsteps.
+
+Which was it, the police, or the kidnappers? The latter, she felt
+morally certain, since the former, in their haste to rescue the child,
+would beyond any question have arrived in an automobile, and at top
+speed.
+
+The newcomers were mounting the stairs in a leisurely manner, as though
+free from any anxiety. Grace heard them pause for a moment on the first
+landing, then start up the second flight of stairs. It seemed to her out
+of the question, to stand in the middle of the room and await their
+entrance. At least she could postpone the fatal moment a little while,
+by hiding, with the boy, in the closet. She stepped into it, the child's
+hand in hers, and drew the door shut, just as the two men entered the
+room. On her way, she hastily blew out the candle.
+
+They were the same two men that she had seen before,--the black-bearded
+man, now without his beard, and the artist, Durand. She saw this, as
+soon as the latter had relit the candle. She wondered if he would notice
+that the wick was still warm. Evidently he did not; for they threw
+themselves into chairs, lit cigarettes, and began to talk.
+
+"Now we can speak freely," said Durand. "How did things go?"
+
+"I got the money--gave the blue signal, and expected to be halfway to
+Brussels by now. What nonsense is this about a red light?"
+
+"It is no nonsense, I assure you. I saw it with my own eyes, as plain as
+day."
+
+"Then Francois must have made a mistake, or else he has been placed
+under arrest--the latter, no doubt. Now the question is, What shall we
+do? I think we ought to get out of Paris as soon as possible. It isn't
+safe to stay here." He looked about him nervously.
+
+"Why not? You didn't telephone Monsieur Stapleton this address, did
+you?"
+
+"No, naturally not."
+
+"Then I don't see but what we are quite safe. No one knows the child is
+here."
+
+"Then you don't intend to give him up?"
+
+"Not yet. I must first find out whether or not Francois is in trouble."
+
+"Let him look out for himself."
+
+The older man frowned. "Since when, my friend," he asked, "have I been
+in the habit of deserting my comrades? Francois must go free, or Mr.
+Stapleton does not get his boy. That's flat. The first thing is to send
+his father something that will let him see that we mean business."
+
+"We've got to be sure about Francois, first."
+
+"I'll find that out, tonight. My plan is this. We must first get the
+child away to Lavillac's place. This is too unsafe, here. Anyone might
+come in."
+
+"They'd have difficulty in finding the hiding place." The younger man
+grinned.
+
+"That's all very well; but the other place is safer. And
+then--Lavillac's woman can look after the brat while we are away. What a
+pity Francois had to get into a mess at the last moment! I hoped to be
+rid of the boy, by now." The older man rose and began striding up and
+down the room.
+
+"Well," he said at length, sharply, "we might as well get along. I move
+that we wrap the boy in a coat, take him down to the car, run quickly
+out to Lavillac's place, leave him there, and start for Brussels at
+once. The rest we can do by 'phone. Francois set free--the boy the same.
+Meanwhile, we've got to show this man Stapleton we mean business; so
+we'd better arrange to send him one of the kid's hands at once. If we
+don't, he'll have the whole Paris police force after us."
+
+"All right. I'll get him out." He strode quickly over to the statue,
+pulled out the side, and gazed blankly into the empty space before him.
+
+"Sacre! The child's gone!" he exclaimed, excitedly. "Somebody has been
+here--in this room--since I left it, half an hour ago."
+
+"The door was locked."
+
+"I know; but somebody's been here, nevertheless, for the child is
+gone."
+
+"He may not be gone, Durand. It is true that he is no longer in the
+house; but he may be in the room, for all that. Search the closet."
+
+The man named Durand stepped quickly to the closet door. "Not much
+chance," he grumbled. "And if the police knew that he was here, and have
+spirited him away, they may even now be waiting to spring a trap of
+which you and I are the rats. For all we know the place is surrounded at
+this very moment."
+
+"Then the sooner we get away from it the better. Search the closet. If
+he's not there, we'd better make tracks for the frontier as quickly as
+possible. We can do nothing more without the child. Francois will have
+to look out for himself."
+
+Durand went impatiently up to the closet door and flung it open, then
+both he and his companion recoiled in surprise as Grace stepped out,
+holding the child by the hand.
+
+"Mon Dieu!" gasped the two men in unison.
+
+The one who had worn the black beard was the first to recover himself.
+"Quick!" he cried, motioning toward Grace. "The woman is a detective.
+Tie her up, and let's get away at once. No doubt she has sent word to
+her friends. We can't afford to stay here another minute." He seemed
+greatly excited and, rushing to the window, inspected the silent street
+below.
+
+Durand, meanwhile, had thrown himself upon the girl, seized her hands,
+and with a quick motion had secured them with a bit of cord he snatched
+from within the closet.
+
+She offered no resistance, made no outcry. Both seemed equally useless.
+The boy stood by, watching the scene in childish wonder. So many queer
+things had happened to him, however, during the past few days, that he,
+too, remained silent.
+
+In a moment the older man withdrew his head from the window, rushed to
+the closet, and drawing out a long gray coat, wrapped it about the
+child. "You will come along with us, Mademoiselle," he said sternly.
+"Make no attempt to escape, if you value your life."
+
+"But what do we want with her?" the younger man asked, impatiently.
+
+"You fool! Would you leave her here, to give our description to the
+police? It would mean certain capture in a few hours. This woman has got
+to be put where she can do no harm until we are safely over the
+frontier. It may be wiser to silence her altogether. We'll decide about
+that when we reach Lavillac's. The first thing is to get out of this
+house without losing a moment's time. Come!" He started for the door.
+
+As he did so, Grace heard, far off, the steady throbbing of an
+automobile. She felt a wave of hope sweep over her. It might be her
+friends, coming to her assistance. If so, they might yet arrive in time.
+
+The two men evidently also heard the sound. "Hurry--hurry!" the older
+one urged, as they began to descend the stairs. "They may be on us at
+any moment. Go out the rear way."
+
+Grace heard the sounds of the approaching automobile growing more and
+more distinct. In another minute it would stop before the door of the
+house. But in that minute her captors would not only have been able to
+descend the stairs, but would already be making good their escape
+through the garden at the rear of the building.
+
+She must do something, she knew, to prevent this; but what--what? Bound
+as she was, how could she hope to prevent the escape of these men. She
+looked ahead of her, to where, a step or two in advance, the man of the
+black beard was hastily descending the stairs, the boy firmly held in
+his arms. Behind her came his companion, candle in hand, close at her
+heels.
+
+They were within half a dozen steps of the lower hall. From this she
+could see a dark passageway, leading to the rear of the house. Already
+the noise of the automobile without told her that it was stopping at the
+door. She heard the sound of rapid footsteps on the sidewalk; yet
+realized that, before her friends could break in, their quarry would
+have flown.
+
+Without a moment's hesitation she sprang forward, throwing her whole
+weight upon the man in front of her.
+
+The sudden shock, as she precipitated herself upon his shoulders, threw
+him off his balance, and he pitched forward headlong into the hallway
+below. The two of them, together with the child, rolled in a tangled
+heap to the floor. The second man, candle in hand, stopped on the stairs
+and gazed helplessly down, not realizing for a moment what had happened.
+
+"Help! Help!" Grace screamed at the top of her voice, as she struggled
+to regain her feet, and at the same moment there came the sound of heavy
+blows upon the front door.
+
+The man who had been carrying the child rose to his feet with an oath,
+just as his companion joined him. He turned on Grace with a howl of
+fury, and struck her a quick blow in the face. She had a confused vision
+of fleeing men, the dancing light of a candle, a rush of fresh air, and
+then all was blotted out in a wave of oblivion.
+
+
+
+
+CHAPTER XIX
+
+
+The startling and dramatic entrance of Richard Duvall into Mr.
+Stapleton's library, ending with his announcement of the whereabouts of
+the kidnapped child, and his subsequent collapse, threw the entire party
+into confusion.
+
+Mrs. Stapleton started up with a scream, her overwrought nerves no
+longer able to resist the frightful strain under which she had for so
+many days been laboring.
+
+Her husband, who had completely forgotten the detective's presence in
+the house, in his anxious vigil at the telephone, called out instantly
+to one of the servants, ordering him to tell Francois to bring his
+automobile to the door.
+
+Monsieur Lefevre, accompanied by Vernet, sprang quickly to Duvall's
+assistance. The Prefect felt that, if the latter's statement was
+correct, he had won out in the long duel for the honor of recovering the
+kidnapped child; but no consideration of this nature could make him any
+less concerned for the detective's welfare, or any the less thankful
+that, no matter by whose efforts, the missing child had at last been
+located. He had hoped that to Grace Duvall would ultimately fall the
+prize of success; but these things were, after all, of no serious
+weight, compared with the great fact, that the success had at last come.
+
+Assisted by Vernet, he placed Duvall upon a couch, and called for
+brandy, and a basin of cold water.
+
+In a few moments, under Vernet's skilful ministrations, the detective's
+wound had been washed and temporarily bound up, and he had been restored
+to consciousness. A little of the brandy soon served to dispel his
+faintness. He declared himself ready to accompany the expedition to
+Passy.
+
+The Prefect endeavored to dissuade him; but to no purpose. The message
+which he had received in the chauffeur's room, to the effect that the
+person calling for help was Grace Duvall, his own wife, seemed so
+mysterious, so utterly inexplicable to him, that he could conceive no
+reasonable explanation for it. There was but one thing to do,--to go
+himself and sift the matter to the bottom. He did not expect to find
+Grace there, and yet--what else could the message mean?
+
+Just as he staggered to his feet, with the announcement that he would
+accompany the party to Passy, two of the servants rushed into the
+library, and with scared faces announced that Francois lay, bound and
+unconscious, on the floor of his room. Mr. Stapleton looked quickly at
+Duvall.
+
+"It's all right, Mr. Stapleton," exclaimed the detective. "The fellow is
+one of the gang." He turned to Monsieur Lefevre. "You'd better have him
+placed under arrest at once. And if your car is here, we'll use that,
+instead of Mr. Stapleton's. There's not a moment to be lost."
+
+"By all means. My automobile is at the door. Vernet," he turned to his
+assistant, "have one of your men take charge of this fellow Francois at
+once. We must set out immediately."
+
+Mr. Stapleton took his wife in his arms, and embraced her tenderly.
+"Don't worry, dear," he said. "I'll be back with the boy, inside of half
+an hour. Come along!" he shouted to the others, as he made for the door.
+"No time to waste now."
+
+In a few moments the entire party, consisting of Mr. Stapleton, Duvall,
+Monsieur Lefevre, Vernet, and the Prefect's chauffeur, were driving
+toward Passy at a rate which set at naught all speed regulations and
+sent the few pedestrians who happened to cross their path scampering to
+the sidewalk for safety.
+
+Duvall explained, as they went along, the mysterious messages which he
+had received by flashlight. No one understood them but Monsieur Lefevre.
+He gave a great sigh of relief. The continued and unexplained absence of
+Grace had alarmed him greatly. Now he began to understand the reasons
+for it. That part of Duvall's story which spoke of haste, the appeal for
+prompt assistance, made him look grave. He leaned over to his chauffeur
+and urged him to even greater speed.
+
+The trees and houses along the Avenue Kleber, and later the Rue
+Franklin, swept by the speeding machine in a whirl of dust. In what
+seemed an incredibly short time the automobile dashed into the Rue
+Nicolo, and thundered up to No. 42.
+
+Vernet was the first to ascend the steps of the house, closely followed
+by Duvall and the others of the party. As they reached the front door,
+and rapped loudly, they all heard a sudden commotion within, followed by
+cries and shouts and a fall. Instantly all four threw their combined
+weight against the door, shattering the lock and bursting it in.
+
+The semidarkness showed a terrifying spectacle. On the floor lay a
+woman, unconscious, clutching in her arms a child, trapped in a long
+gray coat. Down the dark hallway leading to the rear of the house dashed
+the figures of two men. One of them turned, as the attacking party
+entered, and hurled the lighted candle which he bore full into their
+faces. The entire scene was instantly plunged into darkness.
+
+The momentary light of the candle, however, had been sufficient to send
+a thrill of joy through at least one of the entering party. Mr.
+Stapleton recognized, in the white and tearful face of the child, his
+kidnapped boy, and, stooping, raised him tenderly in his arms.
+
+Duvall, not knowing whether the unconscious woman was the supposed agent
+of the police, Mademoiselle Goncourt, or Grace, his wife, lifted her in
+his arms and carried her out into the air.
+
+Vernet, followed by the Prefect, and the chauffeur, who had at once
+joined them, dashed fearlessly along the dark passage by which the two
+men were attempting to escape.
+
+There was a crash, as the rear door was burst out, followed by a volley
+of shots as Vernet opened upon the fleeing men with his automatic
+revolver.
+
+In a moment the affair was over. The foremost of the two men crumpled up
+before he had taken half a dozen strides through the garden, and his
+companion raised his hands and surrendered, begging for mercy. Within a
+few moments he was handcuffed, and Vernet, bending over his wounded
+companion, was directing the chauffeur to summon an ambulance at once.
+
+Monsieur Lefevre returned hastily to the street. His sole concern now
+was for Grace. He prayed fervently that no serious harm had befallen
+her, and realized that Duvall was likely to resent bitterly the
+deception which has been practised upon him.
+
+The latter, however, was in no mood for recriminations. No sooner had he
+carried his unconscious burden to the street, when Grace opened her
+eyes, threw her arms about his neck, and kissed him.
+
+"Richard--Richard!" she cried, happily. "I'm so glad--so glad!" then
+rested content in his arms.
+
+The detective's brain was in a whirl. In no possible way could he
+account for the presence here, in Paris, under such tragic and
+inexplicable circumstances, of the wife whom he had left, so short a
+time before, peacefully sitting on the rosecovered porch of their home
+in Maryland. The thing seemed incredible, unbelievable; yet here was
+Grace, with her soft arms about his neck, her kisses on his lips, to
+prove its reality.
+
+He looked at Monsieur Lefevre dully as the latter joined them upon the
+sidewalk, but could say nothing.
+
+"It seems," remarked the Prefect, with a grave smile, "that not only has
+Mr. Stapleton found his boy, but you have found your wife."
+
+Duvall frowned. "What is she doing here?" he asked.
+
+"We will speak of that later, my friend," observed Lefevre, quietly.
+"Just at present I propose that we return to Mr. Stapleton's without a
+moment's delay. Her heart is breaking with anxiety." He took Grace's arm
+and assisted her to enter the automobile, where Mr. Stapleton had
+already preceded them with his son. "It is to you, my dear child," he
+said to Grace, as she sunk weakly back upon the cushioned seat, "that
+Mrs. Stapleton will owe all her happiness."
+
+It was a cheerful party that broke in upon the banker's wife a short
+time later. Duvall, under the stimulus of Grace's presence, had
+completely forgotten his wound; while Grace, who had been but
+momentarily stunned by the blow which the kidnapper had given her, was
+radiant with joy at once more feeling her husband's arms about her.
+
+Monsieur Lefevre carried them both off to his house, as soon as the boy
+had been restored to his mother. The happiness of the banker's reunited
+family was too great to permit them to be even mildly interested in the
+affairs of Richard Duvall and his wife, and they, too, wished to be
+alone. It seemed to them both as though ages had passed since they had
+seen each other; they could scarcely realize that it had been but a
+little over two weeks. Richard especially seemed unable to grasp the
+truth of the situation. He plied Grace with numberless questions, and
+could scarcely believe that he had actually been within arm's length of
+her on at least four different occasions during the past week without
+knowing it.
+
+Monsieur Lefevre advised him to leave the whole matter until the next
+day. "You should be proud of your wife, Monsieur," he said, gravely.
+"But for her, I doubt if Monsieur Stapleton would ever have seen his boy
+again. And that reminds me," he smiled mischievously, "that I have won
+that little bet. It was Mademoiselle Goncourt, of my office, that
+recovered the lost child."
+
+"I think the honors are pretty evenly divided, Monsieur," laughed Grace,
+happily, as she pressed her husband's hand. "Don't forget that if
+Richard hadn't gotten my message, all my work would have gone for
+nothing."
+
+"Suppose we call it a draw, then," said the Prefect. "All in the family,
+as you Americans say. And to show that I am not prejudiced, one way or
+the other, I suggest that you both, with Mr. and Mrs. Stapleton, dine
+with me tomorrow evening. There are many points connected with this case
+which are by no means cleared up, and we should talk them over. Although
+we have secured the missing child, and three of the kidnappers, we do
+not yet know how the child was stolen, or whether the nurse, Mary
+Lanahan, is innocent or guilty of any part in his mysterious
+disappearance in the Bois de Boulogne. I confess that I have all along
+considered her guilty, and am inclined to order her arrest at once."
+
+"It will be useless, Monsieur," remarked Duvall, quietly. "She is
+entirely innocent."
+
+"You mean that she knows nothing of how the boy was spirited away?"
+
+"Nothing!"
+
+"Mon Dieu! Then the thing may forever remain a mystery."
+
+"Not at all. It is simple enough."
+
+Monsieur Lefevre turned to him with a look of inquiry. "You mean, then,
+that you have solved it?"
+
+"I do."
+
+"Then may I ask that you will be good enough to explain it at once?"
+
+Duvall laughed. "Monsieur Lefevre," he said, "I have a splitting
+headache, a bad wound in my cheek, and a burning desire to spend the
+next two hours talking to my wife." He drew Grace toward him, and put
+his arm through hers. "I am very much afraid that the explanation of
+the disappearance of Mr. Stapleton's boy will have to be put off until
+tomorrow."
+
+Monsieur Lefevre watched the two as they went, arm in arm, up the
+stairs.
+
+"Mon Dieu!" he said softly to himself. "They are just as much in love
+with each other as ever."
+
+
+
+
+CHAPTER XX
+
+
+"I must confess," remarked Monsieur Lefevre, as he sat with Mr.
+Stapleton and Duvall over their after dinner cigars the following
+evening, "that while the case as a whole appears simple enough to me,
+there are one or two points that I fail to understand."
+
+"There are a great many that _I_ fail to understand," exclaimed the
+banker, chewing reflectively on his cigar. "However, now that the boy is
+safe at home, it really makes very little difference."
+
+"On the contrary, Mr. Stapleton," remarked Duvall, "it makes a great
+deal of difference. For instance, I understand that you have discharged
+the nurse, Mary Lanahan."
+
+"Yes. You say that she is quite innocent of any part in the kidnapping
+of my boy; but the fact remains that I don't trust her. I am informed
+that she was married to that fellow, Valentin, this afternoon."
+
+Duvall smiled. "That was quite to be expected."
+
+"At one time," said Mr. Stapleton, "you believed this fellow Valentin to
+have been concerned in the plot."
+
+"Yes. That is true. My early investigations of the matter showed me at
+once that there was some understanding between these two, something
+which they were endeavoring to conceal. I did not at first understand
+the motive which actuated them. I thought it was guilt. In reality, it
+was love. Therefore I am not surprised to learn of their marriage." He
+gazed critically at his cigar for a time, in silence.
+
+"As matters have turned out, gentlemen," he resumed, after a few
+moments, "there is no cause for anything but congratulation on all
+hands. The child is recovered, the criminals are under arrest, the
+money--the hundred thousand dollars you paid out, Mr. Stapleton--was
+found on the kidnapper's person and returned to you."
+
+"Exactly. Nothing could be more satisfactory all around."
+
+"And yet," went on the detective, "I have never before taken part in a
+case in which I have done so little, in which I have been so uniformly
+unsuccessful."
+
+Mr. Stapleton raised his hand. "My dear Duvall," he began, "but for you,
+we should have been nowhere."
+
+"You are wrong, my friend. Had I kept out of the case altogether, your
+son would have been returned to you just the same. It is true that the
+men who kidnapped him would not have been caught, and your money would
+not have been returned to you; but the prime object which you sought,
+the recovery of your child, would have been realized in any event."
+
+"That is true," remarked the Prefect; "but, from the standpoint of the
+police, it is the detection and capture of the criminal that is desired,
+not the buying of him off. By insisting on that, Mr. Stapleton, you
+rendered our work extremely difficult."
+
+"So difficult, indeed," said Duvall, earnestly, "that but for the
+energy, the courage, the wit of a woman, all our plans would have
+failed. I refer to my wife. It is to her that all the credit in this
+affair is due."
+
+"By all means!" said Mr. Stapleton. "I could not fail to realize, when
+she told her story at dinner tonight, how much Mrs. Stapleton and
+myself owe her. I shall have something to say on the subject of our
+debt, as soon as the ladies rejoin us. But tell us, Mr. Duvall, a little
+more about the case, as you now understand it. I confess that I am
+becoming more and more interested. What, for instance, was the mystery,
+if indeed there was any, connected with the box of gold-tipped
+cigarettes?"
+
+Duvall smiled. "That, my dear sir, is in fact the crux, the starting
+point, of the whole affair." He settled back in his chair comfortably.
+"Otherwise the case was simple enough. Certain scoundrels steal a child,
+hold it for ransom, and frighten the parents into paying over a large
+sum. Nothing unusual in that. A clever scheme or two for turning the
+money over, and returning the child--simple, yet perfect enough to defy
+all attempts to foil them.
+
+"The real mystery lay in the utter absence of any clues which would
+throw light on the actual stealing of the child. In this respect the
+case was unique. A trusted nurse swears that the child has disappeared
+in broad daylight, without the slightest knowledge of how it was
+accomplished. Here we have a case so simple, so devoid of incident of
+any sort, that we are baffled at the very start by the impossibility of
+the thing. Yet the nurse is a woman of good reputation, honest, clearly
+telling what she believes to be the truth.
+
+"But a single clue existed upon which I could build the least semblance
+of a case. I refer to the half-smoked cigarette with the gold tip, which
+I discovered in the grass at the scene of the crime. Without that
+apparently trivial clue, the criminals would in all probability never
+have been captured at all."
+
+"But," exclaimed Mr. Stapleton, "I don't see how you make that out."
+
+"Nor I," observed the Prefect.
+
+"No. I suppose not. And yet, it is simple enough. That half-smoked
+cigarette and nothing else is the basic reason for the arrest of the
+three men now in your hands."
+
+Monsieur Lefevre smiled. "Be good enough," he said, "to explain."
+
+"Very well, I will. But first, let me indicate to you my course of
+reasoning. When I originally found the cigarette, I regarded it as of
+very small value, from the standpoint of evidence. It happened to be
+lying in the grass at the point where the crime occurred; but during
+the week or more which had elapsed between the stealing of the boy and
+my examination of the ground, a hundred people might have walked over
+the spot. I took it, because I realized that it _might_ have a bearing
+on the case, and I have learned to discard no clue, however trifling it
+may appear, until it has been proven valueless.
+
+"Now to go back to the cigarette, I observed at once that it was of
+American make, yet of such small size as to have been either used by a
+woman, or by a man of rather effeminate taste.
+
+"Now if the cigarette had been used by a woman, it meant one of two
+things. Either it was used by Mary Lanahan herself, in which case it
+apparently proved nothing, or by some other woman who was there with
+her, and who might have had a hand in the kidnapping.
+
+"On the other hand, if used by a man, it pointed clearly to the
+chauffeur, Valentin, for several reasons. He was a friend, a former
+lover, of the nurse. He had been discharged by Mr. Stapleton for
+dishonesty. He was, I had reason to know, of rather a weak and
+effeminate type. The cigarette was of American make, and he had but
+recently come from America. These things pointed to Valentin. The fact
+that the nurse was in love with him would cause her to shield him. I
+determined to try the matter out at once.
+
+"As soon as I returned to the house, therefore, I confronted her, and
+asked her if Valentin smoked gold-tipped cigarettes. I did this, not
+because I expected to get any reply of value, but because I wished to
+observe her manner, her face, when I flung the question at her.
+
+"She was greatly startled. She denied that Valentin smoked. Fifteen
+minutes later, she sent him a message to destroy the cigarettes.
+
+"I at once concluded that they were working together, and were both
+guilty, a conclusion in which, however much I was justified by the
+evidence, I was quite wrong.
+
+"Then came the attempt on the part of someone--the man with the black
+beard, I am told--to steal the cigarettes from Valentin. I learned that
+the man was followed to Mr. Stapleton's house.
+
+"This at once threw a new light upon the matter, although I will admit a
+confusing one. Someone else, besides the nurse, desired the box of
+cigarettes removed as evidence; someone, in fact, who belonged to, or
+had friends in, the house. Who could this be? I could think of no one,
+outside of Mary Lanahan herself, but the chauffeur, Francois."
+
+"Why did you first suspect him?" asked Mr. Stapleton.
+
+"Because he was the only person, besides the nurse, who was present at
+the time of the kidnapping. I did not abandon my suspicions of either
+the nurse or Valentin. I fully believed that they knew a great deal more
+about the affair than they admitted. But I became convinced that
+Francois, too, was in the thing. He had testified that he was asleep
+when the affair occurred. I concluded at once that he was lying.
+
+"At the first opportunity, therefore, I made a thorough search of his
+room, and found the box of cigarettes hidden in a clock on his mantel."
+
+"Ha! I did not know that," exclaimed the Prefect. "What were they doing
+there?"
+
+"I concluded that the fellow with the black beard who stole them from
+Valentin, in order to prevent their use as evidence against him, turned
+them over to Francois for a definite purpose."
+
+"And that purpose was?"
+
+"Their use in subsequent crimes of a similar nature."
+
+Mr. Stapleton and the Prefect gazed at Duvall in bewilderment. "Explain
+yourself, my friend," exclaimed the latter. "I confess I do not
+understand what you are talking about. Who, may I ask, really smoked the
+cigarette, the remains of which you found in the grass?"
+
+"Mary Lanahan," said the detective, with a smile.
+
+"The nurse! Name of a dog! Then I fail to see that the matter is of the
+slightest importance one way or the other."
+
+"On the contrary, Monsieur, it is of the greatest importance. May I ask
+whether you are, by any chance, familiar with the properties of an
+Eastern drug, made from hemp, and generally known as hashish?"
+
+The Prefect sat up suddenly, and clapped his hands to his knees. "Mon
+Dieu!" he exclaimed. "Now I begin to understand."
+
+"More than I do," said Mr. Stapleton.
+
+"The cigarettes were drugged, that is all," went on Duvall. "The men who
+planned this thing went to work very carefully. They ascertained,
+through Francois, that Mary Lanahan was in the habit, no doubt on the
+sly, of using cigarettes. I discovered the fact, myself, before I left
+New York. They also learned that she smoked the same brand as Mrs.
+Stapleton herself used. No doubt she helped herself from Mrs.
+Stapleton's supply. They therefore secured, also through Francois, a box
+of these cigarettes, and had them heavily drugged with hashish. The box
+of drugged cigarettes was substituted, later on, for her own."
+
+"But," exclaimed Mr. Stapleton, "how could Mary Lanahan swear that she
+turned away but a moment--that no one came near her?"
+
+"When Mary Lanahan testified that, she believed that she was telling the
+truth. The hashish had simply destroyed her conception of the passage of
+time."
+
+"Is that its effect?"
+
+"Yes. It produces a delightful languor, a stupor in which all
+realization of the passage of time ceases. Sometimes, to those who use
+the drug, it may apparently require hours to walk a few yards. To make a
+momentary movement of the hand may seem to take many minutes. On the
+other hand, in the stupor which the drug induces, hours may be spent in
+the contemplation of a flower, a bit of scenery, the page of a book,
+without any realization on the part of the user that more than a few
+seconds have elapsed. That is what happened to Mary Lanahan. She inhaled
+a few puffs of the cigarette, heavily charged with the drug; without
+knowing, of course, of its presence. She probably passed at once into a
+state of stupor which may have extended over fifteen minutes or more.
+She was not unconscious. She sat upon the grass, looking off toward the
+distant sky, in a waking dream, not unlike a trance, in which all the
+world about her--the world of sound, of movement--had simply ceased to
+exist. She was to all intents and purposes unconscious of what was going
+on about her. The kidnapper, whom I strongly suspect to be Francois,
+merely strolled up behind her, picked up the boy, and walked off with
+him."
+
+The detective's listeners looked at him in astonishment. Presently Mr.
+Stapleton spoke. "Why do you think it was Francois?" he asked.
+
+"Oh, for many reasons. Had he, on approaching, found the nurse not
+sufficiently under the influence of the drug, he could have pretended to
+wish to speak to her, on some trivial matter. Again, the child would go
+away with him of course without making an outcry, which he would
+probably not have done, with a stranger. There are other reasons. He no
+doubt took the boy to the road, and handed him to his confederates,
+passing in another car. The affair occurred, you will remember, in a
+little frequented part of the Bois.
+
+"The subsequent actions of Mary Lanahan are a trifle difficult to
+account for; but I suppose them to have been as follows: On slowly
+coming out of her stupor, and realizing that the boy was gone, she was
+terribly frightened. It had seemed to her but a moment since she turned
+away. She fears that the cigarette has made her drowsy--she has heard
+that they sometimes contain opium. She thinks she may have dozed off;
+but is not willing to admit it. Especially does she not want her
+employers to know that she uses cigarettes. She fears that such
+knowledge would cost her her place. It is not until later that she
+begins to suspect the cigarettes."
+
+"When is that?" inquired Lefevre.
+
+"Several days later, when she is supposed to have been poisoned. She was
+with Valentin at the time; although, on account of Mr. Stapleton's
+dislike for him, she feared to admit it. She smokes another of the
+cigarettes, while sitting on a bench with him, in the Champs Elysees.
+Suddenly she is taken ill--a frequent result of hashish, when taken in
+excessive doses, or by one otherwise nervously upset. Valentin takes the
+box, puts her into a cab, and goes to his room, where he leaves the
+cigarettes. No doubt, as she begins to feel ill, she discusses with him
+the possibility of the cigarettes having been poisoned. It is for that
+reason that she gives them to him.
+
+"Her sudden message to Valentin to destroy them arose from a fear that I
+would discover the part which they had played in the boy's loss. This
+would, she knew, not only cost her her place, but would make her, in a
+way, responsible for the entire affair. She feared Mr. Stapleton's
+wrath, and therefore both she and Valentin remained dumb, so far as the
+cigarettes were concerned.
+
+"They both, however, were all this time doing their best to find the
+child. Her message to Valentin, that she was suspicious of Francois,
+telling Valentin to watch him, arose no doubt from a realization that
+the box of drugged cigarettes had been substituted for her own by the
+chauffeur.
+
+"Valentin, acting on her advice, does watch Francois, as his presence
+clinging to the rear of the latter's car the other night has proved. He
+tells me, today, that Francois did not take his car to the garage that
+night at all. The men there who so testified lied, at his request,
+supposing it merely an excuse to cover a joy ride.
+
+"Francois, not wishing that the drugged cigarettes should remain in the
+nurse's hands as evidence against him, evidently made an attempt to
+recover them, discovered that she had turned them over to Valentin, and,
+being watched himself, sent word of the matter to his confederate, the
+fellow who went about in the black beard. He must have been admitted to
+Mr. Stapleton's house that night by Francois himself.
+
+"I came to the conclusion, early in the course of my investigations,
+that the cigarette, the end of which I had found in the Bois, had been
+smoked by Mary Lanahan, and I so told Mr. Stapleton."
+
+The banker nodded. "Yes," he said; "but you did not then say anything
+about the hashish."
+
+"I was not certain of it. I intended to have the fragment I had found
+analyzed. When I discovered the cigarettes in Francois' room, you will
+remember that I took one of them. I smoked that cigarette, before going
+to bed that night. It produced exactly the sensations that Mary Lanahan
+must have felt. I floated away in the land of dreams for over half an
+hour, and came to with no recollection whatever of the passage of time.
+It is a remarkable drug, but an extremely dangerous one.
+
+"After that, the case became simple enough. I knew at once, beyond any
+question, that Francois was one of the kidnappers. My plans last night
+would have worked perfectly, but for the chauffeur's accidental
+discovery of me, hiding in the closet. Had that not happened, the boy
+would have been returned, according to program, and Francois I had
+safely in my hands."
+
+"But we wouldn't have got the others," laughed the Prefect. "You must
+thank your wife for that. Vernet has told me how the kidnappers
+outwitted you at the Avenue Malakoff. The car from which the signal
+apparently was made contained a well known stockbroker, who knew nothing
+of the matter at all. He merely happened to be passing the Avenue
+Malakoff at the precise moment when the signal was given to Francois."
+
+"You are mistaken, Monsieur," observed the detective, quietly. "The
+signal was undoubtedly made from that car; not by Monsieur Lemaitre, I
+will admit, but by his chauffeur. He has admitted to Vernet that a
+stranger paid him fifty francs to do so, on the plea that it was some
+signal to a woman. The man knows nothing of the affair, beyond that."
+
+As he finished speaking, there was a ripple of laughter from the hall,
+and Mrs. Stapleton, Madame Lefevre, and Grace came in.
+
+"We have been debating a most important question," said Mrs. Stapleton,
+with an assumption of extreme gravity, "and we beg that you, Monsieur
+Lefevre, will be so good as to decide it."
+
+"What is this question so grave, Madame," inquired the Prefect, rising,
+with a smile. "I am all impatience to hear it."
+
+"The question is this, Monsieur Lefevre: Which deserves the greater
+credit for the recovery of my boy--Mr. Duvall, or his charming wife?"
+
+The Prefect stepped forward, placed one hand affectionately upon
+Duvall's shoulder, and with the other grasped Grace by the arm.
+
+"The question you propound, Madame," he said, looking from the detective
+to his wife with a smile, "is easily answered. The credit belongs
+equally to both. And that, my children, is as it should be. This affair,
+so happily terminated, has taught me one important lesson. It is this:
+The husband and the wife should never be in opposition to each other.
+They must work together always, not only in matters of this sort, but in
+all the affairs of life. I attempted a risky experiment in allowing
+these two dear friends of mine to attack this case from opposite sides.
+But for some very excellent strokes of luck, it might have resulted most
+unhappily for all concerned. Hereafter, should Monsieur Duvall and his
+wife serve me, it must be together, or not at all." He turned to Grace.
+"I feel that I owe you both a great debt, my child, for having once
+again so rudely interrupted the course of your honeymoon. What
+reparation can I make? Ask of me what you will."
+
+"Anything?" inquired Grace, laughing.
+
+"Anything." The Prefect bowed gallantly.
+
+"Then I demand your promise, Monsieur, to visit us at our place in
+Maryland, before the end of the year."
+
+"That," exclaimed the Prefect, as he bent and kissed her hand, "would be
+the most delightful way of paying a debt that I could possibly
+imagine."

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of

+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.

+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.

+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.

+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
