“And Captain Dettmar?” she queried.

“Has been drinking, that is all. I shall get rid of him at Attu-Attu.”

But before Duncan climbed into his bunk, he strapped around himself, against the skin and under his pajama coat, a heavy automatic pistol.

He fell asleep almost immediately, for his was the gift of perfect relaxation. He did things tensely, in the way savages do, but the instant the need passed he relaxed, mind and body. So it was that he slept, while the rain still poured on deck and the yacht plunged and rolled in the brief, sharp sea caused by the squall.

He awoke with a feeling of suffocation and heaviness. The electric fans had stopped, and the air was thick and stifling. Mentally cursing all Lorenzos and storage batteries, he heard his wife moving in the adjoining stateroom and pass out into the main cabin. Evidently heading for the fresher air on deck, he thought, and decided it was a good example to imitate. Putting on his slippers and tucking a pillow and a blanket under his arm, he followed her. As he was about to emerge from the companionway, the ship's clock in the cabin began to strike and he stopped to listen. Four bells sounded. It was two in the morning. From without came the creaking of the gaff-jaw against the mast. The Samoset rolled and righted on a sea, and in the light breeze her canvas gave forth a hollow thrum.

He was just putting his foot out on the damp deck when he heard his wife scream. It was a startled frightened scream that ended in a splash overside. He leaped out and ran aft. In the dim starlight he could make out her head and shoulders disappearing astern in the lazy wake.

“What was it?” Captain Dettmar, who was at the wheel, asked.

“Mrs. Duncan,” was Duncan's reply, as he tore the life-buoy from its hook and flung it aft. “Jibe over to starboard and come up on the wind!” he commanded.

And then Boyd Duncan made a mistake. He dived overboard.

When he came up, he glimpsed the blue-light on the buoy, which had ignited automatically when it struck the water. He swam for it, and found Minnie had reached it first.
