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 trespass, 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 butter, ranging swiftly over the tree-clad shore of a burnished black lagoon, picking out en passant 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 passively 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 shore, the distance was nothing less than two hundred yards.
