There remained the chance that the paper had been stolen by one of the two German agents--by either without the knowledge of the other.
If Baron von Harden had found it--necessarily before Lanyard returned to the room--he had subsequently been at elaborate pains to conceal his success from both his victim and his confederate. Why? Did he distrust the latter? Again, why?
If "Karl" had been the thief, it must have been after Lanyard"s return, and while the Baron was preoccupied with the task of keeping the prisoner quiet, to let the search proceed.
In that event "Karl" had lied deliberately to his superior. Why? Because the doc.u.ment was salable, and "Karl" intended to realize its value for his personal benefit?
Not an unlikely explanation. Nor could this be called the first instance in which the Prussian spy system, admirably organized though it was, had been betrayed by one of its own agents.
This hypothesis, too, accounted for that most perplexing circ.u.mstance of all, the murder of Baron von Harden. For Lanyard was fully persuaded that had been nothing less than premeditated murder, in no way an accident of faulty aim. Even the most nervous and unstrung man could hardly have missed six shots out of seven, point blank. A nervous man, indeed, could hardly have gained his own consent to take so hideous a chance of injuring or killing a collaborator.
It appeared, then, that one of four things had happened to the cylinder of paper:
Miss Brooke had taken it back into her own care. In which case Lanyard was no more concerned.
Captain Osborne had secured it through Mr. Warde. This, however, Lanyard did not seriously credit.
It had gone to the bottom when the _a.s.syrian_ sank with the body--among others--of Baron von Harden.
Or "Karl" had stolen it.
Privately, indeed, Lanyard rather inclined to hope that the last might prove to be the true solution. He desired earnestly to meet "Karl" once more, on equal terms. And the more counts in the score, the greater his satisfaction in exacting a reckoning in full.
But he antic.i.p.ated. That chapter might only too possibly have been closed forever by the hand of Death. As yet he knew nothing concerning the mortality of the _a.s.syrian_ debacle. He had not enquired of the officers of the U-boat because they knew little if anything more than he. Their gla.s.ses had discovered to them trouble with the lifeboats; they had spoken of one boat capsizing, of "people going overboard like cattle." There must have been many drownings, even with a United States destroyer near by and speeding to the rescue.
A single question troubled Lanyard greatly. Officers and crew of the U-boat had betrayed profoundest consternation upon the advent of that destroyer, presumably a warship of a neutral nation. And that same ship had without hesitation fired upon the submarine.
Was it possible, then, that the United States had already declared war on Germany?
It seemed extremely probable; in such event these Germans would have been notified instantly by wireless from the New York bureau of their country"s Secret Service; whereas, Captain Osborne, receiving the same advice by wireless, might reasonably have kept it quiet lest the news stir to more formidable activity those agents of the Wilhelmstra.s.se whose presence among the pa.s.sengers he must at least have strongly suspected.
Presently the closeness of the atmosphere began to work upon Lanyard"s perceptions. In spite of his long rest, a new drowsiness drugged his senses. He yielded without struggle, knowing he would soon need every ounce of strength and vitality that sleep could give him....
The din of an inferno startled him awake. Those narrow metal walls were echoing a clangour of machinery maniacal in character and overpowering in volume. Clankings, tappings, hissings, coughings, clatterings, stridulation of a wireless spark, drone of dynamos, shrewdish scolding of Diesel motors developing two thousand horsepower, individual efforts of some two thousand valves, combined--or, declined to combine--in a cacophony like nothing under the sun but the chant of a submersible under way on the surface.
Lanyard, gratefully aware of a current of fresh air sweeping through the hold, rolled out of his bunk to find that, while he slept, clothing had been provided for him, rough but adequate; heavy woollen underwear and socks, a sweater, a dungaree coat, trousers of the same stuff, all vilely damp, and a friendless pair of oil-sodden shoes: the sweepings of a dozen lockers, but as welcome as disreputable.
Dressed, he turned aft through the alleyway, entering immediately the central operating room and storm center of that typhoon of noise, a wilderness of polished machinery in active being.
Of the score or more leather-clad machinists silent at their posts, none paid him more heed than a pa.s.sing, incurious glance as he crossed to a narrow steel companion ladder and ascended to the conning tower. This he found deserted; but its deck-hatch was open. He climbed out to the bridge.
The night was calm and heavily overcast, with no sea more than long, slow swells. Through its windless quiet the U-boat racketed with the raving abandon of the Spirit of Discord on a spree in a boiler factory. To the riot of its internal strife was added the remonstrance of waters sliced by the stem and flung back by the sides, a prolonged and stertorous hiss like the rending of an endless sheet of canvas.
To eyes new from the electric illumination of the hold, the blackness was positive, with the palpable quality of an element, relieved alone by the dull glow of the binnacle housing the gyroscope telltale, from which the faintest of golden reflections struck back to pick out a pair of seemingly severed fists gripping the handles of the bridge steering wheel with a singular effect of desperation.
For some moments Lanyard could see nothing more.
The mirthless chuckle of the lieutenant sounded at his elbow.
"So the good Herr Doctor thought he had better come up for air, eh? My friend, the very dead might envy you the sincerity of your slumbers. We have been half an hour on the surface, with all this uproar--and you are only just wakened!"
"Half an hour?" Lanyard repeated thoughtfully. "Then we should be close in...."
"Give us ten minutes more ... if we don"t go aground in this accursed blackness!"
A broad-shouldered body pa.s.sed between Lanyard and the binnacle, momentarily eclipsing its light. Down below in the operating room a bell shrilled, and of a sudden the Diesels were silenced.
The dead quiet that followed the sharp extinction of that hubbub was as startling as the detonation of high explosive had been.
Through this sudden stillness the submarine slipped stealthily, the hissing beneath her bows dying down to gentle sibilance.
From forward the calls of an invisible leadsman were audible. In response the commander uttered throaty orders to the helmsman at his elbow, and those unattached hands shifted the wheel minutely.
Lanyard started to speak, but a growl from the captain, and a touch of the lieutenant"s hand on his sleeve cautioned him to silence.
There was a small pause. The vessel seemed to have lost way altogether, to swim like a spirit ship that Stygian tide. The lieutenant moved forward, leaving Lanyard alone. The voice of the leadsman was stilled. By the wheel the captain stood absolutely motionless, his body vaguely silhouetted against the glow of the binnacle. The hands that gripped the wheel so savagely were as steady as if carven out of stone. An atmosphere of suspense enveloped the boat like a cloud.
Lanyard grew conscious of something huge and formidable, a denser shadow in the darkness beyond the bows, the loom of land. Off to starboard a point of light appeared abruptly, precisely as if a golden pin had punctured the black blanket of the night. The captain growled gutturals of relief and command. The hands on the wheel shifted, steering exceeding small. A second light shone out to port, then shifted slowly into range with the first, till the two were as one. Again the bell sang in the operating room, and the vessel forged ahead quietly to the urge of electric motors alone. A third light and a fourth appeared, well apart to port and starboard, the range lights precisely equidistant between them. Between these the U-boat moved swiftly. They swam back on either hand and were abruptly extinguished as if the night, resenting their insolent trespa.s.s, had gobbled both at a gulp.
The temperature became sensibly warmer and the salt air of the sea was strongly tinctured with the sweet smell of pines and forest mould.
Up forward carbons sputtered and spat; a searchlight was unsheathed and carved the gloom as if it was b.u.t.ter, ranging swiftly over the tree-clad sh.o.r.e of a burnished black lagoon, picking out en pa.s.sant several unpainted wooden structures, then steadying on a long and substantial landing stage, on which several men stood waiting.

AT BASE
As the U-boat, with motors dead and way lessening, glided up alongside the head of that T-shaped landing stage and was made fast, the wireless operator popped up from below, saluted the commander, and delivered a written message.
Lanyard, instinctively aware that this was the expected report from Seventy-ninth Street on Dr. Paul Rodiek, quietly pulled himself together and took quick observations.
At best his chances in the all-too-probable emergency were far from brilliant. Yet one might better perish trying, however hopelessly, than pa.s.sively submit to being shot down.
The lieutenant, waspishly superintending the work of crew and base guards at the mooring lines, stood preoccupied within an arm"s length; while the landing stage was a fair six feet away. From its T-head to the sh.o.r.e, the distance was nothing less than two hundred yards.
Desperate action and miraculous luck might take the Prussian by surprise and enable one to s.n.a.t.c.h the service automatic from its holster at his belt, leap to the stage, and shoot a way landward through the guards cl.u.s.tered there; after which everything would depend on swiftness of foot and the uncertain light permitting one to gain a refuge in the surrounding woodland without a bullet in one"s back.
It was a sorry hope....
With catlike attention Lanyard watched the hands holding that paper to the binnacle light--large hands, heavy and muscular but tremulous with drink and nervous reaction from the long strain and c.u.mulative horror of the cruise then ending. Their aim would not be good, except by accident. None the less, if the report were unfavourable, their first gesture would be toward the holster, signalling to Lanyard that the moment had come to initiate heroic measures.
The Bavarian was an unconscionable time absorbing the import of the message. Bending his face close to the paper, the better to make out the writing, he read with moving lips, slowly, a doltish frown of concentration clouding his congested countenance.
At length, however, he stood up, swaying a little as he folded and pocketed the paper.
