Chapter 17
“You see, down there I placed the couples of the thermopile beneath the electric furnace on the table. Here I have the mechanism, operated by the feeble current from the thermopile, opening and closing switches, and actuating bells and lights. Then, too, I have the recording instrument. The thing is fundamentally very simple and is based on well-known phenomena. It is not uncertain and can be tested at any time, just as I did then, when I showed a slight fall in temperature. Of course it is not the slight changes I am after, not the gradual but the sudden changes in temperature.”
“I see,” said Carton. “If there is a drop, the current goes one way and we see the red light; a rise and it goes the other, and we see a green light.”
“Exactly,” agreed Kennedy. “No one is going to approach that chamber down-stairs as long as he thinks any one is watching, and we do not know where they are watching. But the moment any sudden great change is registered, such as turning on that electric furnace, we shall know it here.”
It must have been an hour that we sat there discussing the merits of the case and speculating on the strange actions of Loraine Keith.
Suddenly the red light flashed out brilliantly.
“What’s that?” asked Carton quickly.
“I can’t tell, yet,” remarked Kennedy. “Perhaps it is nothing at all. Perhaps it is a draught of cold air from opening the door. We shall have to wait and see.”
We bent over the little machine, straining our eyes and ears to catch the visual and audible signals which it gave.
Gradually the light faded, as the thermopile adjusted itself to the change in temperature.
Suddenly, without warning, a low-toned bell rang before us and a bright-green light flashed up.
“That can have only one meaning,” cried Craig excitedly. “Some one is down there in that inferno—perhaps the bomb-maker himself.”
The bell continued to ring and the light to glow, showing that whoever was there had actually started the electric furnace. What was he preparing to do? I felt that, even though we knew there was some one there, it did us little good. I, for one, had no relish for the job of bearding such a lion in his den.
We looked at Kennedy, wondering what he would do next. From the package in which he had brought the two registering machines he quietly took another package, wrapped up, about eighteen inches long and apparently very heavy. As he did so he kept his attention fixed on the telethermometer. Was he going to wait until the bomb-maker had finished what he had come to accomplish?
It was perhaps fifteen minutes after our first alarm that the signals began to weaken.
“Does that mean that he has gone—escaped?” inquired Carton anxiously.
“No. It means that his furnace is going at full power and that he has forgotten it. It is what I am waiting for. Come on.”
Seizing the package as he hurried from the room, Kennedy dashed out on the street and down the outside cellar stairs, followed by us.
He paused at the thick door and listened. Apparently there was not a sound from the other side, except a whir of a motor and a roar which might have been from the furnace. Softly he tried the door. It was locked on the inside.
Was the bomb-maker there still? He must be. Suppose he heard us. Would he hesitate a moment to send us all to perdition along with himself?
How were we to get past that door? Really, the deathlike stillness on the other side was more mysterious than would have been the detonation of some of the criminal’s explosive.
Kennedy had evidently satisfied himself on one point. If we were to get into that chamber we must do it ourselves, and we must do it quickly.
From the package which he carried he pulled out a stubby little cylinder, perhaps eighteen inches long, very heavy, with a short stump of a lever projecting from one side. Between the stonework of a chimney and the barred door he laid it horizontally, jamming in some pieces of wood to wedge it tighter.
Then he began to pump on the handle vigorously. The almost impregnable door seemed slowly to bulge. Still there was no sign of life from within. Had the bomb-maker left before we arrived?
“This is my scientific sledge-hammer,” panted Kennedy, as he worked the little lever backward and forward more quickly—“a hydraulic ram. There is no swinging of axes or wielding of crowbars necessary in breaking down an obstruction like this, nowadays. Such things are obsolete. This little jimmy, if you want to call it that, has a power of ten tons. That ought to be enough.”
It seemed as if the door were slowly being crushed in before the irresistible ten-ton punch of the hydraulic ram.
Kennedy stopped. Evidently he did not dare to crush the door in altogether. Quickly he released the ram and placed it vertically. Under the now-yawning door jamb he inserted a powerful claw of the ram and again he began to work the handle.
A moment later the powerful door buckled, and Kennedy deftly swung it outward so that it fell with a crash on the cellar floor.
As the noise reverberated, there came a sound of a muttered curse from the cavern. Some one was there.
We pressed forward.
On the floor, in the weird glare of the little furnace, lay a man and a woman, the light playing over their ghastly, set features.
Kennedy knelt over the man, who was nearest the door.
“Call a doctor, quick,” he ordered, reaching over and feeling the pulse of the woman, who had half fallen out of her chair. “They will, be all right soon. They took what they thought was their usual adulterated cocaine—see, here is the box in which it was. Instead, I filled the box with the pure drug. They’ll come around. Besides, Carton needs both of them in his fight.”
“Don’t take any more,” muttered the woman, half conscious. “There’s something wrong with it, Haddon.”
I looked more closely at the face in the half-darkness.
It was Haddon himself.
“I knew he’d come back when the craving for the drug became intense enough,” remarked Kennedy.
Carton looked at Kennedy in amazement. Haddon was the last person in the world whom he had evidently expected to discover here.
“How—what do you mean?”
“The episode of the telephone booth gave me the first hint. That is the favourite stunt of the drug fiend—a few minutes alone, and he thinks no one is the wiser about his habit. Then, too, there was the story about his speed mania. That is a frequent failing of the cocainist. The drug, too, was killing his interest in Loraine Keith—that is the last stage.
“Yet under its influence, just as with his lobbygow and lieutenant, Brodie, he found power and inspiration. With him it took the form of bombs to protect himself in his graft.”
“He can’t—escape this time—Loraine. We’ll leave it—at his house—you know—Carton—”
We looked quickly at the work-table. On it was a gigantic bomb of clockwork over which Haddon had been working. The cocaine which was to have given him inspiration had, thanks to Kennedy, overcome him.
Beside Loraine Keith were a suit-case and a Gladstone. She had evidently been stuffing the corners full of their favourite nepenthe, for, as Kennedy reached down and turned over the closely packed woman’s finery and the few articles belonging to Haddon, innumerable packets from the cabinet dropped out.
“Hulloa—what’s this?” he exclaimed, as he came to a huge roll of bills and a mass of silver and gold coin. “Trying to double-cross us all the time. That was her clever game—to give him the hours he needed to gather what money he could save and make a clean getaway. Even cocaine doesn’t destroy the interest of men and women in that,” he concluded, turning over to Carton the wealth which Haddon had amassed as one of the meanest grafters of the city of graft.
Here was a case which I could not help letting the Star have immediately. Notes or no notes, it was local news of the first order. Besides, anything that concerned Carton was of the highest political significance.
It kept me late at the office and I overslept. Consequently I did not see much of Craig the next morning, especially as he told me he had nothing special, having turned down a case of a robbery of a safe, on the ground that the police were much better fitted to catch ordinary yeggmen than he was. During the day, therefore, I helped in directing the following up of the Haddon case for the Star.
Then, suddenly, a new front page story crowded this one of the main headlines. With a sigh of relief, I glanced at the new thriller, found it had something to do with the Navy Department, and that it came from as far away as Washington. There was no reason now why others could not carry on the graft story, and I left, not unwillingly. My special work just now was keeping on the trail of Kennedy, and I was glad to go back to the apartment and wait for him.
“I suppose you saw that despatch from Washington in this afternoon’s papers?” he queried, as he came in, tossing a late edition of the Record down on my desk.
Across the front page extended a huge black scare-head: “NAVY’S MOST VITAL SECRET STOLEN.”
“Yes,” I shrugged, “but you can’t get me much excited by what the rewrite men on the Record say.”
“Why?” he asked, going directly into his own room.
“Well,” I replied, glancing through the text of the story, “the actual facts are practically the same as in the other papers. Take this, for instance, ‘On the night of the celebration of the anniversary of the battle of Manila there were stolen from the Navy Department plans which the Record learns exclusively represent the greatest naval secret in the world.’ So much for that paragraph—written in the office. Then it goes on:
“The whole secret-service machinery of the Government has been put in operation. No one has been able to extract from the authorities the exact secret which was stolen, but it is believed to be an invention which will revolutionise the structure and construction of the most modern monster battleships. Such knowledge, it is said, in the hands of experts might prove fatal in almost any fight in which our newer ships met others of about equal fighting power, as with it marksmen might direct a shot that would disable our ships.
“It is the opinion of the experts that the theft was executed by a skilled draughtsman or other civilian employe. At any rate, the thief knew what to take and its value. There is, at least, one nation, it is asserted, which faces the problem of bringing its ships up to the standard of our own to which the plans would be very valuable.
“The building had been thrown open to the public for the display of fireworks on the Monument grounds before it. The plans are said to have been on one of the draughting-tables, drawn upon linen to be made into blue-prints. They are known to have been on the tables when the draughting-room was locked for the night.
“The room is on the third floor of the Department and has a balcony looking out on the Monument. Many officers and officials had their families and friends on the balcony to witness the celebration, though it is not known that any one was in the draughting-room itself. All were admitted to the building on passes. The plans were tacked to a draughting-board in the room, but when it was opened in the morning the linen sheet was gone, and so were the thumb-tacks. The plans could readily have been rolled into a small bundle and carried under a coat or wrap.
“While the authorities are trying to minimise the actual loss, it is believed that this position is only an attempt to allay the great public concern.”
I paused. “Now then,” I added, picking up one of the other papers I had brought up-town myself, “take the Express. It says that the plans were important, but would have been made public in a few months, anyhow. Here:
“The theft—or mislaying, as the Department hopes it will prove to be—took place several days ago. Official confirmation of the report is lacking, but from trustworthy unofficial sources it is learned that only unimportant parts of plans are missing, presumably minor structural details of battle-ship construction, and other things of a really trivial character, such as copies of naval regulations, etc.
“The attempt to make a sensational connection between the loss and a controversy which is now going on with a foreign government is greatly to be deplored and is emphatically asserted to be utterly baseless. It bears traces of the jingoism of those ‘interests’ which are urging naval increases.
“There is usually very little about a battle-ship that is not known before her keel is laid, or even before the signing of the contracts. At any rate, when it is asserted that the plans represent the dernier cri in some form of war preparation, it is well to remember that a ‘last cry’ is last only until there is a later. Naval secrets are few, anyway, and as it takes some years to apply them, this loss cannot be of superlative value to any one. Still, there is, of course, a market for such information in spite of the progress toward disarmament, but the rule in this case will be the rule as in a horse trade, ‘Caveat emptor.’”
“So there you are,” I concluded. “You pay your penny for a paper, and you take your choice.”
“And the Star,” inquired Kennedy, coming to the door and adding with an aggravating grin, “the infallible?”
“The Star,” I replied, unruffled, “hits the point squarely when it says that whether the plans were of immediate importance or not, the real point is that if they could be stolen, really important things could be taken also. For instance, ‘The thought of what the thief might have stolen has caused much more alarm than the knowledge of what he has succeeded in taking.’ I think it is about time those people in Washington stopped the leak if—”
The telephone rang insistently.
“I think that’s for me,” exclaimed Craig, bounding out of his room and forgetting his quiz of me. “Hello—yes—is that you, Burke? At the Grand Central—half an hour—all right. I’m bringing Jameson. Good-bye.”
Kennedy jammed down the receiver on the hook.
XIX
THE SUBMARINE MYSTERY
“The Star was not far from right, Walter,” he added, seriously. “If the battleship plans could be stolen, other things could be—other things were. You remember Burke of the secret service? I’m going up to Lookout Hill on the Connecticut shore of the Sound with him to-night. The rewrite men on the Record didn’t have the facts, but they had accurate imaginations. The most vital secret that any navy ever had, that would have enabled us in a couple of years to whip the navies of the world combined against us, has been stolen.”
“And that is?” I asked.
“The practical working-out of the newest of sciences, the science of telautomatics.”
“Telautomatics?” I repeated.
“Yes. There is something weird, fascinating about the very idea. I sit up here safely in this room, turning switches, pressing buttons, depressing levers. Ten miles away a vehicle, a ship, an aeroplane, a submarine obeys me. It may carry enough of the latest and most powerful explosive that modern science can invent, enough, if exploded, to rival the worst of earthquakes. Yet it obeys my will. It goes where I direct it. It explodes where I want it. And it wipes off the face of the earth anything which I want annihilated.
“That’s telautomatics, and that is what has been stolen from our navy and dimly sensed by you clever newspaper men, from whom even the secret service can’t quite hide everything. The publication of the rumour alone that the government knows it has lost something has put the secret service in a hole. What might have been done quietly and in a few days has got to be done in the glare of the limelight and with the blare of a brass band—and it has got to be done right away, too. Come on, Walter. I’ve thrown together all we shall need for one night—and it doesn’t include any pajamas, either.”
A few minutes later we met our friend Burke of the secret service at the new terminal. He had wired Kennedy earlier in the day saying that he would be in New York and would call him up.
“The plans, as I told you in my message,” began Burke, when we had seated ourselves in a compartment of the Pullman, “were those of Captain Shirley, covering the wireless-controlled submarine. The old captain is a thoroughbred, too. I’ve known him in Washington. Comes of an old New England, family with plenty of money but more brains. For years he has been working on this science of radio-telautomatics, has all kinds of patents, which he has dedicated to the United States, too. Of course the basic, pioneer patents are not his. His work has been in the practical application of them. And, Kennedy, there are some secrets about his latest work that he has not patented; he has given them outright to the Navy Department, because they are too valuable even to patent.”
Burke, who liked a good detective tale himself, seemed pleased at holding Kennedy spellbound.
“For instance,” he went on, “he has on the bay up here a submarine which can be made into a crewless dirigible. He calls it the Turtle, I believe, because that was the name of the first American submarine built by Dr. Bushnell during the Revolution, even before Fulton.”
“You have theories of your own on the case?” asked Craig.
“Well, there are several possibilities. You know there are submarine companies in this country, bitter rivals. They might like to have those plans. Then, too, there are foreign governments.”
He paused. Though he said nothing, I felt that there was no doubt what he hinted at. At least one government occurred to me which would like the plans above all others.
“Once some plans of a submarine were stolen, I recall,” ruminated Kennedy. “But that theft, I am satisfied, was committed in behalf of a rival company.”
“But, Kennedy,” exclaimed Burke, “it was bad enough when the plans were stolen. Now Captain Shirley wires me that some one must have tampered with his model. It doesn’t work right. He even believes that his own life may be threatened. And there is scarcely a real clue,” he added dejectedly. “Of course we are watching all the employes who had access to the draughting-room and tracing everybody who was in the building that night. I have a complete list of them. There are three or four who will bear watching. For instance, there is a young attache of one of the embassies, named Nordheim.”
“Nordheim!” I echoed, involuntarily. I had expected an Oriental name.
“Yes, a German. I have been looking up his record, and I find that once he was connected in some way with the famous Titan Iron Works, at Kiel, Germany. We began watching him day before yesterday, but suddenly he disappeared. Then, there is a society woman in Washington, a Mrs. Bayard Brainard, who was at the Department that night. We have been trying to find her. To-day I got word that she was summering in the cottage colony across the bay from Lookout Hill. At any rate, I had to go up there to see the captain, and I thought I’d kill a whole flock of birds with one stone. The chief thought, too, that if you’d take the case with us you had best start on it up there. Next, you will no doubt want to go back to Washington with me.”
Lookout Hill was the name of the famous old estate of the Shirleys, on a point of land jutting out into Long Island Sound and with a neighbouring point enclosing a large, deep, safe harbour. On the highest ground of the estate, with a perfect view of both harbour and sound, stood a large stone house, the home of Captain Shirley, of the United States navy, retired.
Captain Shirley, a man of sixty-two or three, bronzed and wiry, met us eagerly.
“So this is Professor Kennedy; I’m glad to meet you, sir,” he welcomed, clasping Craig’s hand in both of his—a fine figure as he stood erect in the light of the portecochere. “What’s the news from Washington, Burke? Any clues?”
“I can hardly tell,” replied the secret service man, with assumed cheerfulness. “By the way, you’ll have to excuse me for a few minutes while I run back into town on a little errand. Meanwhile, Captain, will you explain to Professor Kennedy just how things are? Perhaps he’d better begin by seeing the Turtle herself.”
Burke had not waited longer than to take leave.
“The Turtle,” repeated the captain, leading the way into the house. “Well, I did call it that at first. But I prefer to call it the Z99. You know the first submarines, abroad at least, were sometimes called Al, A2, A3, and so on. They were of the diving, plunging type, that is, they submerged on an inclined keel, nose down, like the Hollands. Then came the B type, in which the hydroplane appeared; the C type, in which it was more prominent, and a D type, where submergence is on a perfectly even keel, somewhat like our Lakes. Well, this boat of mine is a last word—the Z99. Call it the Turtle, if you like.”
We were standing for a moment in a wide Colonial hall in which a fire was crackling in a huge brick fireplace, taking the chill off the night air.
“Let me give you a demonstration, first,” added the captain. “Perhaps Z99 will work—perhaps not.”
There was an air of disappointment about the old veteran as he spoke, uncertainly now, of what a short time ago he had known to be a certainty and one of the greatest it had ever been given the inventive mind of man to know.
A slip of a girl entered from the library, saw us, paused, and was about to turn back. Silhouetted against the curtained door, there was health, animation, gracefulness, in every line of her wavy chestnut hair, her soft, sparkling brown eyes, her white dress and hat to match, which contrasted with the healthy glow of tan on her full neck and arms, and her dainty little white shoes, ready for anything from tennis to tango.
“My daughter Gladys, Professor Kennedy and Mr. Jameson,” introduced the captain. “We are going to try the Z99 again, Gladys.”
A moment later we four were walking to the edge of the cliff where Captain Shirley had a sort of workshop and signal-station.
He lighted the gas, for Lookout Hill was only on the edge of the town and boasted gas, electricity, and all modern improvements, as well as the atmosphere of old New England.
“The Z99 is moored just below us at my private dock,” began the captain. “I have a shed down there where we usually keep her, but I expected you, and she is waiting, thoroughly overhauled. I have signalled to my men—fellows I can trust, too, who used to be with me in the navy—to cast her off. There—now we are ready.”
The captain turned a switch. Instantly a couple of hundred feet below us, on the dark and rippling water, a light broke forth. Another signal, and the light changed.
It was moving.
“The principle of the thing,” said Captain Shirley, talking to us but watching the moving light intently, “briefly, is that I use the Hertzian waves to actuate relays on the Z99. That is, I send a child with a message, the grown man, through the relay, so to speak, does the work. So, you see, I can sit up here and send my little David out anywhere to strike down a huge Goliath.
“I won’t bore you, yet, with explanations of my radio-combinator, the telecommutator, the aerial coherer relay, and the rest of the technicalities of wireless control of dirigible, self-propelled vessels. They are well known, beginning with pioneers like Wilson and Gardner in England, Roberts in Australia, Wirth and Lirpa in Germany, Gabet in France, and Tesla, Edison, Sims, and the younger Hammond in our own country.
