A shiver ran through the body of the Prussian. He pulled himself together with obvious effort, looked up with an uncertain grin, and pa.s.sed a shaking hand across his writhing lips.

"All foolishness, of course, but 'gets on one's nerves ... constant a.s.sociation with man like that.... 'Know what he's doing now, or was, when I came away? Sitting up with doors and windows locked and blinds drawn, drinking brandy neat. He can't sleep by night if sober, or without 'light in the room. If he does, he knows they will get him ... people he hears crawling up from the sea, slopping round the house, mumbling, whimpering in the dark--"

He broke off abruptly, with a whisper more dreadful than a shriek--"_G.o.d_!"--and jumped to his feet, whipping the automatic from his belt.

A footfall sounded in one of the after compartments. Others followed.

Someone was coming slowly down the alleyway, someone with dragging, heavy feet.

The lieutenant waited motionless, as one petrified with terror.

The bulkhead doorway framed the figure of the commander. He paused there, louring at his subaltern with haunted eyes ablaze in a face like parchment.

"So!" he said, nodding. "As I thought. It is thus I find you, fraternising with one who may be, for all we know, an enemy to the Fatherland. You drunken, babbling fool! Get ash.o.r.e!" His angry foot thumped the grating.

"Get ash.o.r.e, and report yourself under arrest!"

With no more warning than a strangled snarl, the lieutenant shot him through the head.

XI

UNDER THE ROSE

Vague stupefaction replaced the scowl upon the countenance of the commander. He swayed, a hand faltering to his forehead, where dark blood was beginning to well from a cleanly drilled puncture. Then he collapsed completely, falling p.r.o.ne across the raised sill of the bulkhead opening. A convulsive tremor shook savagely his huge frame.

Thereafter he was quite still.

The report of that one shot had reverberated stunningly within those narrow walls of steel. Momentarily Lanyard looked to see the alarmed anchor watch appear; so too, apparently, the lieutenant, who remained immobile, pistol poised in a hand for the moment strangely steady, gaze fixed upon the mouth of the alleyway.

But through a long minute no other sounds were audible than that ceaseless dripping from frames and seams, with that muted, terrible mouthing of waters on the plates.

Unable either to fathom or forecast the workings of the drink-maddened mentality masked by that rat-like face, Lanyard waited with a hand covertly grasping the automatic in his pocket. There was no telling; at any moment that murderous mania might veer his way. And he was not content to die, not yet, not in any event by the hand of a decadent little beast of a Boche.

Slowly the arm of the lieutenant dropped, lowering the pistol till its muzzle chattered on the top of the table: a noise that broke the spell upon his senses. He looked down in dull brutish wonder, then roused and with a gesture of horror let the weapon fall clattering.

His glance shifting to the body of his commander, he started violently, backing up against the plates to put all possible distance between himself and his handiwork. His lips moved, framing phrases at first incoherent, presently articulate in part:

"... _done it at last!... Knew I must soon_...."

Abruptly he looked up at Lanyard.

"Bear witness," he cried: "I was provoked beyond human endurance. He insulted me in your presence ... me!... that sc.u.m!"

Lanyard said nothing, but met his gaze with a blank, non-committal stare, under which the eyes of the lieutenant wavered and fell.

Then with a start he realised anew the significance of that still figure at his feet, and tried to shake some of the swagger back into his wretched, fear-racked being.

"A good job!" he muttered defiantly. "And you will stand by me, I know....

Only there is nothing in that, of course, no justification possible before a court martial. Even your testimony could not save me ... I am done for, utterly...."

He hung his head. Lanyard heard whispered words: "_degraded," "dishonour,"

"firing squad_"....

A chronometer in the central operating compartment tolled eight bells.

With a sharp cry the lieutenant dropped to his knees. "He can't be dead!"

he shrilled. "It is all play-acting, to frighten me!"

Frantically he sought to turn the body over.

Lanyard's hand shot swiftly out, capturing the automatic on the table. With rapid and sure gestures he extracted and pocketed the clip, drew back the breech, ejecting into his palm the one sh.e.l.l in the barrel, and replaced the weapon, all before the Prussian gave over his insane efforts to resurrect the dead.

"He is dead enough," he announced, eyeing Lanyard morosely--"beyond helping.... Look here; are you with me or against me?"

"Need you ask?"

"I count on you, then. Good. I think we can cover this up."

He checked and stood for a while lost in thought.

"How?" Lanyard roused him.

"Simply enough: I go on deck, send the watch ash.o.r.e on some trumped-up errand. They suspect nothing, thinking the commander and I have you in charge. If they heard that shot, I will say one of us dropped a bottle of champagne, and it exploded.... When they are gone, I bring the dory alongside; and with your help it should be an easy matter to carry this body up, weight it, row it out to the middle of the lagoon, dump it overboard. Then we return. Our story is, the commander followed the anchor watch ash.o.r.e; if later he wandered off, got lost in the woods in his alcoholic delirium, that is no affair of ours. Do you understand?"

"Perfectly," said Lanyard with a look of fatuous innocence. "But how about the water--is it deep enough?"

The Prussian took no pains to dissemble his scorn of this question, seemingly so witless. "To cover the body? Why, even here there is sufficient depth at low tide for us to submerge completely, barring the periscopes. And it is deeper yet in the middle."

"Thanks," Lanyard replied meekly.

"Have another drink? No?" The Prussian tossed off a half cupful of undiluted brandy, and shuddered. "Then stop here. I'll be back in a--"

"Half a minute." The lieutenant halted in the act of stepping across the body. Lanyard levelled a hand at the automatic. "Do you mind taking that with you? I have no desire to be found here with it and a dead man, should anything prevent your return."

With a sickly grimace the murderer s.n.a.t.c.hed up the weapon, thrust it in its holster, and hurriedly departed.

Lanyard watched him pa.s.s through the alleyway and turn toward the companion ladder, then followed quietly.

As the lieutenant climbed out on deck, Lanyard ascended to the conning tower and waited there, listening. He could not quite make out what was said; but after a few brusque words of command two pair of boots rang on the gangplank and thumped away down the stage. At the same time Lanyard let himself noiselessly out through the hatch.

As soon as his vision grew reconciled to the change from light to darkness, he discovered the slender figure of the lieutenant skulking on tip-toe after the retreating anchor watch; about midway on the landing stage, however, he paused and bent over one of the piles, apparently fumbling with the painter of a small boat moored in the black shadows below.

At this Lanyard began to move along the deck, one by one working the mooring lines clear of their cleats and dropping them gently overboard, till but two were left to hold the U-boat in place.

Throughout he kept watch upon the manoeuvres of the lieutenant--saw him drop over the side of the stage, heard a thump of feet as he landed in a boat, and a subsequent creak of oar-locks.
