The small boat was rounding the bows of the submarine when the adventurer ducked back through conning tower to hold.
He was standing where he had been left when the lieutenant came below.
"It"s all right," this last announced with shabby bravado as he stepped over the body in the doorway. "We are rid of that d.a.m.ned watch for a time.
They won"t return within half an hour at least. I have the dory moored amidships. If we are lively, this dirty job will be over in no time at all."
Lanyard nodded. "I am ready."
"No need to hurry--plenty of time for one more drink." The Prussian splashed brandy into the cup, filling it to the brim. "And G.o.d knows I need it!"
Lanyard watched critically as, with head well back, he drained that staggering dose of raw spirit gulp by gulp without once removing the cup from his lips. No mortal man could drink like that and stand up under it: it was now a mere question of time....
Hardly that: the hand of the murderer shook and wavered widely as he put down the cup. For a moment he swayed with eyes fixed and glazing, features visibly losing plasticity, then lurched forward, knocking the brandy bottle to the floor, swung around a full half turn in blind effort to re-establish equilibrium, fell backward upon the table, and lay racked from head to foot with savage spasms, hands clawing empty air, chest labouring vainly to win sufficient oxygen to combat the poison with which his system was saturated.
Moving to his side, Lanyard laid a hand upon the left breast. The man"s heart was hammering his ribs with agonizing blows, at first rapid, by degrees more slow and feeble.
No power on earth could save him now: he had committed suicide as surely as murder.
Wasting not another glance or thought upon him Lanyard hurried aft to the central operating room.
The time he had spent there, an hour earlier, was by no means lost in purposeless marvelling. He boasted a certain apt.i.tude for mechanics, perhaps legitimately inherited from that obscure origin of his, largely fostered by the requirements of his craft; into the bargain, he had been privileged ere now to gain some slight insight into the principles of submersible operation. If obliged to work swiftly and in some instances upon the advice of intuition rather than practical knowledge, he went not unintelligently about his task, made few false moves.
Turning first to the diving controls, he adjusted the hydroplanes to their extreme downward inclination, then made the rounds of the vent valves, opening all wide. With a sharp hissing and whistling the air from the auxiliary tanks was driven inboard, and as Lanyard manipulated the wheels operating the forward and aft groups of Kingston valves, to the hissing was added the suck and gurgle of water flooding the main and auxiliary ballast and adjusting tanks.
Immediately the U-boat began to sink. Lanyard delayed only to close the switches which controlled the electric motors. As their drone gained volume he grasped the rifle and swarmed up the companion-ladder, pa.s.sing through the conning tower to deck with little or nothing to spare--with, in fact, barely time to throw off the two mooring lines and jump into the small boat before water, sweeping hungrily up over deck and bridge, began to cascade through conning tower and torpedo hatchways.
Constrained to cut the painter lest the dory be drawn down with the fast-sinking submarine, he fitted oars to locks and put his back to them, swinging the small boat hastily clear of whirlpools which formed as the waves closed over the spot where the U-boat had rested.
From first to last less than five minutes" activity had been needed for the task of scotching this water-moccasin of the salt seas and putting its keepers at the mercy of the country whose hospitality they had too long abused.
Well content, after a little, Lanyard lay on his oars and contemplated with much interest what the night permitted to be visible: the landing stage, no more than a dark, vague ma.s.s in the darkness; the land picked out with but few lights, mainly at windows of the base buildings, painting dim ribbons upon the polished floor of the lagoon.
Methodically these were eclipsed as a moving figure pa.s.sed before them.
Listening intently, Lanyard could distinguish the slow footfalls of an unsuspecting sentry--no other sounds, more than gentle voices of the night: murmurs of blind wavelets, the plaintive whisper of a little breeze belated amid the tree-tops of that dark forest, and a slow, weary soughing of swells upon the distant ocean sh.o.r.e.
Perceiving as yet not the slightest indication of an alarm ash.o.r.e, Lanyard ventured to continue rowing, but with utmost caution, lifting and dipping his blades as gingerly as though they were fashioned of brittle gla.s.s, and for want of a better guide keeping the stern of the dory square to the shank of the T-stage.
In time the bows grounded lightly on sand. The melancholy voice of the sea now seemed a heavier sighing in the stillness. He pushed off and rowed on parallel with a dark sh.o.r.e line, so close in that his starboard oar touched bottom at each stroke.
At intervals he paused and rested, striving vainly to garner some clue to his bearings. Inexorably the blackness forbade that. He might have failed ere dawn to grope a way out of that trap had not the disappearance of the submarine been discovered within the hour.
A sudden clamour rose in the quarter of the landing stage, first one great shout of dismay, then two voices bellowing together, then others. Several rifle-shots were fired in the air. More lights broke out in windows ash.o.r.e.
Many feet drummed resoundingly upon the stage, and the confusion of voices attained a pitch of wild, hysteric uproar. Of a sudden a flare was lighted and tossed far out upon the bosom of the lagoon.
Surprised by that sharp and merciless blue glare, Lanyard instinctively shipped oars and picked up the rifle. He could see so clearly that huddle of figures upon the head of the landing stage that he confidently apprehended being fired upon at any moment; but minutes lengthened and he was not. Either the Germans were looking for bigger game than a dory adrift, or the dazzling flare hindered more than aided their vision.
At length persuaded that he had not been detected, Lanyard put aside the rifle and resumed the oars. Now his course was made beautifully clear to him: the blue light showed him that outlet to the sea which he sought within a hundred yards" distance.
Presently the flare began to wane. It was not renewed. Altogether unseen, unsuspected, Lanyard swung the dory into the breach, and drove it seaward with all his might.
Swiftly the lagoon was shut out by narrow closing banks. The blue glare died out behind a black profile of rounded dunes. Lanyard turned the bow eastward, rowing broadside to the sh.o.r.e.
After something more than an hour of this mode of progress, he struck in toward the beach, disembarked in ankle-deep waters, slung the rifle over his shoulder by its strap and, pushing the dory off, abandoned it to the whim of the sea.
Then again he set his face to the east, following the contour of the beach just within the wash of the tide: thereby making sure that there should be no trail of footprints in the sand to guide a possible pursuit in the morning.
The rising sun found him purposefully splashing on, weary but enheartened by the discovery that he had left behind the more thickly wooded section of the island.
Presently, turning in to the dry beach for the first time, he climbed to the summit of a dune somewhat higher than its fellows, and took observations, finding that he had come near to the eastern extremity of the island.
At some distance to his right a wagon road, faintly rutted in sand and overgrown with beach gra.s.s, struck inland.
Following this at a venture, he came, at about eight o"clock, upon the outskirts of a waterside community.
Before proceeding he hid the magazine rifle in a thicket, then made a wide detour, and picked up a roadway which entered the village from the north.
If his disreputable appearance was calculated to excite comment, readiness in disbursing money to remedy such shortcomings made amends for Lanyard"s taciturnity. Within two hours, shaved, bathed, and inconspicuously dressed in a cheap suit of ready-made clothing, he was breakfasting famously upon the plain fare of a commercial tavern.
The town, he learned, was the one-time important whaling port of Edgartown.
He would be able to leave for the mainland on a ferry steamer sailing early in the afternoon.
Ten minutes before going abroad he filed a long telegram in code addressed to the head of the British Secret Service in New York....
Consequences manifold and various ensued.
When the telegram had been delivered and decoded--both transactions being marked by reasonable prompt.i.tude--the head of the British Secret Service in New York called the British Emba.s.sy in Washington on the long distance telephone.
Shortly thereafter an attache of the British Emba.s.sy jumped into a motor-car and had himself driven to one of the cardinal departments of the Federal Government.
When he had kicked his heels in an antechamber upward of an hour, he was received, affably enough, by the head of the department, a smug, open-faced gentleman whose mood was largely preoccupied with illusions of grandeur, who was, in short, interested far more in considering how splendid it was to be himself than in hearing about any mare"s-nest of a German U-boat base on the south sh.o.r.e of Martha"s Vineyard.
He was, however, indulgent enough to promise to give the matter his distinguished consideration in due course.
He even went so far as to have his secretary make a note of what alleged information this young Englishman had to impart.
During the night he chanced to wake up and recall the matter, and concluded that, all things considered, it would do no harm to give the United States Navy a little amus.e.m.e.nt and exercise, even if it should turn out that the rumour of this submarine base was a canard.
So, the next morning, he went to his desk some time before noon, and issued a lot of orders. One of them had to do with the necessity for absolute secrecy.
During the day several minor officials of the department might have been, and indeed were, observed going about their business with painfully tight-lipped expressions.
Also many messages were transmitted by wireless, telephone, and telegraph, to various persons charged with the defense of the Atlantic Coast; some of these were code messages, some were not.
That same night a great forest fire sprang up on the south sh.o.r.e of Martha"s Vineyard, both preceded and accompanied by a series of heavy explosions.
The first United States vessel to reach the lagoon found only charred remains of a landing stage and several buildings and, at the bottom of the lagoon, an incoherent ma.s.s of wreckage, a twisted and shattered chaos of steel plates and framework that might possibly have been a perfectly sound submarine, though sunken, had somebody not been warned in ample time to permit its destruction through the agency of trinitrotoluene, that enormously efficient modern explosive nicknamed by British military and naval experts "T.N.T.," and by the Germans "Trotyl."
