The Leak

by Jacques Futrelle

his eyes and glared straight into those ofthe financier. "Someone listened at the window?" he went on after amoment.

  "No. It is sixteen stories up, fronting the street, and there is no fireescape."

  "Or the door?"

  "If you knew the arrangement of my offices, you would see how utterlyimpossible that would be, because--"

  "Nothing is impossible, Mr. Grayson," snapped the scientist abruptly."It might be improbable, but not impossible. Don't say that--it annoysme exceedingly." He was silent for a moment. Grayson stared at himblankly. "Did either you or she answer a call on the 'phone?"

  "No one called; we called no one."

  "Any apertures--holes or cracks--in your flooring or walls or ceilings?"demanded the scientist.

  "Private detectives whom I had employed looked for such an opening, andthere was none," replied Grayson.

  Again The Thinking Machine was silent for a long time. Grayson lighted afresh cigar and settled back in his chair patiently. Faint cobwebbylines began to appear on the dome-like brow of the scientist, and slowlythe squint eyes were narrowing.

  "The letters you wrote were intercepted?" he suggested at last.

  "No," exclaimed Grayson flatly. "Those letters were sent direct to thebrokers by a dozen different methods, and every one of them had beendelivered by five minutes of ten o'clock, when 'Change begins business.The last one left me at ten minutes of ten."

  "Dear me! Dear me!" The Thinking Machine rose and paced the length ofthe room.

  "You don't give me credit for the extraordinary precautions I havetaken, particularly in this last P., Q. & X. deal," Grayson continued."I left positively nothing undone to insure absolute secrecy. And MissWinthrop, I know, is innocent of any connection with the affair. Theprivate detectives suspected her at first, as you do, and she waswatched in and out of my office for weeks. When she was not under myeyes, she was under the eyes of men to whom I had promised anextravagant sum of money if they found the leak. She didn't know itthen, and doesn't know it now. I am heartily ashamed of it all, becausethe investigation proved her absolute loyalty to me. On this last dayshe was directly under my eyes for two hours; and she didn't make onemovement that I didn't note, because the thing meant millions to me.That proved beyond all question that it was no fault of hers. What couldI do?"

  The Thinking Machine didn't say. He paused at a window, and for minuteafter minute stood motionless there, with eyes narrowed to mere slits.

  "I was on the point of discharging Miss Winthrop," the financier wenton, "but her innocence was so thoroughly proved to me by this lastaffair that it would have been unjust, and so----"

  Suddenly the scientist turned upon his visitor. "Do you talk in yoursleep?" he demanded.

  "No," was the prompt reply. "I had thought of that too. It is beyond allordinary things, Professor. Yet there is a leak that is costing memillions."

  "It comes down to this, Mr. Grayson," The Thinking Machine informed himcrabbedly. "If only you and Miss Winthrop knew those plans, and no oneelse, and they did leak, and were not deduced from other things, theneither you or she permitted them to leak, intentionally orunintentionally. That is as pure logic as two and two make four; thereis no need to argue it."

  "Well, of course, I didn't," said Grayson.

  "Then Miss Winthrop did," declared The Thinking Machine finally,positively; "unless we credit the opposition, as you call it, withtelepathic gifts hitherto unheard of. By the way, you have referred tothe other side only as the opposition. Do the same men, the same clique,appear against you all the time, or is it only one man?"

  "It's a clique," explained the financier, "with millions back of it,headed by Ralph Matthews, a young man to whom I give credit for beingthe prime factor against me." His lips were set sternly.

  "Why?" demanded the scientist.

  "Because every time he sees me he grins," was the reply. Grayson seemedsuddenly discomfited.

  The Thinking Machine went to a desk, addressed an envelope, folded asheet of paper, placed it inside, then sealed it. At length he turnedback to his visitor. "Is Miss Winthrop at your office now?"

  "Yes."

  "Let us go there, then."

  A few minutes later the eminent financier ushered the eminent scientistinto his private office on the Street. The only person there was a youngwoman--a woman of twenty-six or-seven, perhaps--who turned, saw Grayson,and resumed reading. The financier motioned to a seat. Instead ofsitting, however, The Thinking Machine went straight to Miss Winthropand extended a sealed envelop to her.

  "Mr. Ralph Matthews asked me to hand you this," he said.

  The young woman glanced up into his face frankly, yet with a certaintimidity, took the envelope, and turned it curiously in her hand.

  "Mr. Ralph Matthews," she repeated, as if the name was a strange one. "Idon't think I know him."

  The Thinking Machine stood staring at her aggressively, as she openedthe envelope and drew out the sheet of paper. There was no expressionsave surprise--bewilderment, rather--to be read on her face.

  "Why, it's a blank sheet!" she remarked, puzzled.

  The scientist turned suddenly toward Grayson, who had witnessed theincident with frank astonishment in his eyes. "Your telephone a moment,please," he requested.

  "Certainly; here," replied Grayson.

  "This will do," remarked the scientist.

  He leaned forward over the desk where Miss Winthrop sat, still gazing athim in a sort of bewilderment, picked up the receiver, and held it tohis ear. A few moments later he was talking to Hutchinson Hatch,reporter.

  "I merely wanted to ask you to meet me at my apartment in an hour," saidthe scientist. "It is very important."

  That was all. He hung up the receiver, paused for a moment to admire anexquisitely wrought silver box--a "vanity" box--on Miss Winthrop's desk,beside the telephone, then took a seat beside Grayson and began todiscourse almost pleasantly upon the prevailing meteorologicalconditions. Grayson merely stared; Miss Winthrop continued her reading.

  Professor Augustus S. F. X. Van Dusen, distinguished scientist, andHutchinson Hatch, newspaper reporter, were poking round among thechimney pots and other obstructions on the roof of a skyscraper. Farbelow them the slumber-enshrouded city was spread out like a panorama,streets dotted brilliantly with lights, and roofs hazily visible throughmists of night. Above, the infinite blackness hung like a veil, withstarpoints breaking through here and there.

  "Here are the wires," Hatch said at last, and he stooped.

  The Thinking Machine knelt on the roof beside him, and for severalminutes they remained thus in the darkness, with only the glow of aflashlight to indicate their presence. Finally, The Thinking Machinerose.

  "That's the wire you want, Mr. Hatch," he said. "I'll leave the rest ofit to you."

  "Are you sure?" asked the reporter.

  "I am always sure," was the tart response.

  Hatch opened a small handsatchel and removed several queerly wroughttools. These he spread on the roof beside him; then, kneeling again,began his work. For half an hour he labored in the gloom, with only theflashlight to aid him, and then he rose.

  "It's all right," he said.

  The Thinking Machine examined the work that had been done, grunted hissatisfaction, and together they went to the skylight, leaving a thin,insulated wire behind them, stringing along to mark their path. Theypassed down through the roof and into the darkness of the hall of theupper story. Here the light was extinguished. From far below came thefaint echo of a man's footsteps as the watchman passed through thesilent, deserted building.

  "Be careful!" warned The Thinking Machine.

  They went along the hall to a room in the rear, and still the wiretrailed behind. At the last door they stopped. The Thinking Machinefumbled with some keys, then opened the way. Here an electric light wason. The room was bare of furniture, the only sign of recent occupancybeing a telephone instrument on the wall.

  Here The Thinking Machine s
topped and stared at the spool of wire whichhe had permitted to wind off as he walked, and his thin face expresseddoubt.

  "It wouldn't be safe," he said at last, "to leave the wire exposed as wehave left it. True, this floor is not occupied; but someone might passthis way and disturb it. You take the spool, go back to the roof,winding the wire as you go, then swing the spool down to me over theside of the building, so that I can bring it in through the window. Thatwill be best. I will catch it here, and thus there will be nothing toindicate any connection." Hatch went out quietly and closed the door.

  Twice the following day The Thinking Machine spoke to the financier overthe telephone. Grayson was in his private office, Miss Winthrop at herdesk, when the first call came.

  "Be careful in answering my questions," warned The Thinking Machine whenGrayson answered. "Do you know how long Miss Winthrop has owned thelittle silver box which is now on her desk, near the telephone?"

  Grayson glanced round involuntarily to where the girl sat idly turningover the leaves of her book. "Yes," he answered, "for seven months. Igave it to her last Christmas."

  "Ah!" exclaimed the scientist. "That simplifies matters. Where did youbuy it?"

  Grayson mentioned the name of a well-known jeweler.

  Considerably later in the day The Thinking Machine called Grayson to thetelephone again.

  "What make of typewriter does she use?" came the querulous voice overthe wire.

  Grayson named it.

  While Grayson sat with deeply perplexed lines in his face, thediminutive scientist called upon Hutchinson Hatch at his office.

  "Do you use a typewriter?" demanded The Thinking Machine.

  "Yes."

  "What kind?"

  "Oh, four or five kinds--we have half a dozen different makes in theoffice."

  They passed along through the city room, at that moment practicallydeserted, until finally the watery blue eyes settled upon a typewriterwith the name emblazoned on the front.

  "That's it!" exclaimed The Thinking Machine. "Write something on it," hedirected Hatch.

  Hatch drew up a chair and rolled off several lines of the immortalpractice sentence, beginning, "Now is the time for all good men--"

  The Thinking Machine sat beside him, squinting across the room in deepabstraction, and listening intently. His head was turned away from thereporter, but his ear was within a few inches of the machine. For half aminute he sat there listening, then shook his head.

  "Strike your vowels," he commanded; "first slowly, then rapidly."

  Again Hatch obeyed, while the scientist listened. And again he shook hishead. Then in turn every make of machine in the office was tested thesame way. At the end The Thinking Machine rose and went his way. Therewas an expression nearly approaching complete bewilderment on his face.

  * * * * *

  For hour after hour that night The Thinking Machine half lay in a hugechair in his laboratory, with eyes turned uncompromisingly upward, andan expression of complete concentration on his face. There was no changeeither in his position or his gaze as minute succeeded minute; the browwas deeply wrinkled now, and the thin line of the lips was drawn taut.The tiny clock in the reception room struck ten, eleven, twelve, andfinally one. At just half-past one The Thinking Machine rose suddenly.

  "Positively I am getting stupid!" he grumbled half aloud. "Of course! Ofcourse! Why couldn't I have thought of that in the first place?..."

  So it came about that Grayson did not go to his office on the followingmorning at the usual time. Instead, he called again upon The ThinkingMachine in eager, expectant response to a note which had reached him athis home just before he started to his office.

  "Nothing yet," said The Thinking Machine as the financier entered. "Buthere is something you must do today. At one o'clock," the scientist wenton, "you must issue orders for a gigantic deal of some sort; and youmust issue them precisely as you have issued them in the past; theremust be no variation. Dictate the letters as you have always done toMiss Winthrop--_but don't send them_! When they come to you, keep themuntil you see me."

  "You mean that the deal must be purely imaginative?" inquired thefinancier.

  "Precisely," was the reply. "But make your instructions circumstantial;give them enough detail to make them absolutely logical and convincing."

  Grayson asked a dozen questions, answers to which were curtly denied,then went to his office. The Thinking Machine again called Hatch on thetelephone.

  "I've got it," he announced briefly. "I want the best telegraph operatoryou know. Bring him along and meet me in the room on the top floor wherethe telephone is at precisely fifteen minutes before one o'clocktoday."

  "Telegraph operator?" Hatch repeated.

  "That's what I said--telegraph operator!" replied the scientistirritably. "Goodbye."

  Hatch smiled whimsically at the other end as he heard the receiverbanged on the hook--smiled because he knew the eccentric ways of thissingular man, whose mind so accurately illuminated every problem towhich it was directed. Then he went out to the telegraph room andborrowed the principal operator. They were in the little room on the topfloor at precisely fifteen minutes of one.

  The operator glanced about in astonishment. The room was stillunfurnished, save for the telephone box on the wall.

  "What do I do?" he asked The Thinking Machine.

  "I'll tell you when the time comes," responded the scientist, as heglanced at his watch.

  At three minutes of one o'clock he handed a sheet of blank paper to theoperator, and gave him final instructions.

  There was ludicrous mystification on the operator's face; but he obeyedorders, grinning cheerfully at Hatch as he tilted his cigar up to keepthe smoke out of his eyes. The Thinking Machine stood impatientlylooking on, watch in hand. Hatch didn't know what was happening, but hewas interested.

  At last the operator heard something. His face became suddenly alert. Hecontinued to listen for a moment, and then came a smile of recognition.

  * * * * *

  Less than ten minutes after Miss Winthrop had handed over thetypewritten letters of instruction to Grayson for signature, and whilehe still sat turning them over in his hands, the door opened and TheThinking Machine entered. He tossed a folded sheet of paper on the deskbefore Grayson, and went straight to Miss Winthrop.

  "So you did know Mr. Ralph Matthews after all?" he inquired.

  The girl rose from her desk, and a flash of some subtle emotion passedover her face. "What do you mean, sir?" she demanded.

  "You might as well remove the silver box," The Thinking Machine went onmercilessly. "There is no further need of the connection."

  Miss Winthrop glanced down at the telephone extension on her desk, andher hand darted toward it. The silver "vanity" box was directly underthe receiver, supporting it, so that all weight was removed from thehook, and the line was open. She snatched the box and the receiverdropped back on the hook. The Thinking Machine turned to Grayson.

  "It was Miss Winthrop," he said.

  "Miss Winthrop!" exclaimed Grayson, "I can't believe it!"

  "Read the paper I gave you, Mr. Grayson," directed The Thinking Machinecoldly. "Perhaps that will enlighten her."

  The financier opened the sheet, which had remained folded in his hand,and glanced at what was written there. Slowly he read it aloud:"PEABODY--Sell ten thousand shares L. & W. at 97. MCCRACKEN Co.--Sellten thousand shares L. & W. at 97." He read on down the list,bewildered. Then gradually, as he realized the import of what he read,there came a hardening of the lines about his mouth.

  "I understand, Miss Winthrop," he said at last. "This is the substanceof the orders I dictated, and in some way you made them known to personsfor whom they were not intended. I don't know how you did it, of course;but I understand that you did do it, so----" He stepped to the door andopened it with grave courtesy. "You may go now."

  Miss Winthrop made no
plea--merely bowed and went out. Grayson stoodstaring after her for a moment, then turned to The Thinking Machine andmotioned him to a chair. "What happened?" he asked briskly.

  "Miss Winthrop is a tremendously clever woman," replied The ThinkingMachine. "She neglected to tell you, however, that besides being astenographer and typist she is also a telegraph operator. She is soexpert in each of her lines that she combined the two, if I may say itthat way. In other words, in writing on the typewriter, she was cleverenough to be able to _give the click of the machine the patterns in theMorse telegraphic code_--so that another telegraph operator at the otherend of the 'phone could hear her machine and translate the clicks intowords."

  Grayson sat staring at him incredulously. "I still don't understand," hesaid finally.

  The Thinking Machine rose and went to Miss Winthrop's desk. "Here is anextension telephone with the receiver on the hook. It happens that thelittle silver box which you gave Miss Winthrop is just tall enough tolift this receiver clear of the hook, and the minute the receiver is offthe hook the line is open. When you were at your desk and she was here,you couldn't see this telephone; therefore it was a simple matter forher to lift the receiver, and place the silver box underneath, thusholding the line open permanently.
