And the dead silence of the ship was made audible by a stealthy drip-drip of water from the seams, and the furtive slaver of the tide on the outer plates.

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

"All foolishness, of course, but 'gets on one's nerves … constant association 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—"God!"—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 ashore!" His angry foot thumped the grating. "Get ashore, and report yourself under arrest!"

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