"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 a.s.serted, 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 pa.s.ses. 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 a.s.serted 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 a.s.serted 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. "h.e.l.lo--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 sh.o.r.e 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 b.u.t.tons, 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 bra.s.s 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 emba.s.sies, 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 t.i.tan 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 a.s.sumed 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."
