The ship, thrown broadside to the wide-spaced swells, had rolled endlessly with a monotonous motion. But now the deck beneath him was steadying. It assumed an abnormal levelness. The boat rose and fell with the waves, but it no longer rolled. There was something beneath holding, drawing on it.

Thorpe knew in that frozen second what it meant. The drum clattered to the rail as he dashed for his room. Gun in hand, he watched with staring eyes where the deserted deck showed dim and vague in the light of the stars and the bow of the ship was lost in the uncertain dark of night.

Wide-eyed he watched into the blackness, and he listened with desperate attention for some slightest sound beyond the splashing of waves and the creaking of spars.

Far in the west a light appeared, to glow and vanish and glow again in the tumbling waters. The Bennington! His heart leaped at the thought, then sank as he knew the destroyer's lights would not appear from that direction.

Through a slow hour that seemed an eternity the oncoming ship drew near, and he knew with a sudden, startling certainty that it was the Adelaide—and Ruth Allaire—coming on, through into the horror awaiting.

He leaned forward tensely as a sound reached his ears. A ghostly echo of a sound, like the softest of smooth, slipping fabric upon hard steel. And as he listened, before his staring eyes, a something came between him and the lighted yacht.

It wavered and swung in the darkness. It was formless, uncertain of outline, and it swung in the night out beyond the ship's rail till it suddenly neared, waved high overhead, and the cold light of the stars shone in pale reflection from an enormous, staring eye.

It surmounted a serpentine form that took shape in the dim radiance without and came lower in undulating folds to crash heavily upon the deck.
