He strained his ears, but the sound, if sound it were, was not repeated. He was impatient for MacLean to appear with the lantern, but he could no longer hear MacLean's footfalls. Then his ears caught another sound; it was peculiar, like the patter of bare feet.

"MacLean! Where are you?" he called sharply. "Hurry with that lantern!"

Instead of MacLean's voice in reply, he heard a heavy breathing, the sound of a man taking several long, sobbing breaths. The breathing ceased immediately, but a light patter followed it, and then the scrape of a shod foot across the deck. The sounds came from just ahead, close by, but he could see nothing. But he sensed some kind of a struggle was taking place on the deck.

He started forward, and then stopped dead. Out of the black void before him came MacLean's voice—strangled words in a horrible, ascending pitch:

"Marty! Marty! My God! Ah-h-h!"

There, was the thud of a heavy, falling body striking the deck.

For a second Martin was anchored by horror. Then he leaped forward, giving voice as he did to a great, arousing, wordless bellow. And even as he ran blindly ahead those few paces, he heard a heavy voice give a shouted supplement to his call.

The darkness was suddenly alive with rushing feet. A body hurled itself against him, an arm struck a sweeping blow, and he felt the knife rip through his flannel shirt and graze his shoulder near his neck.

He went reeling backward, his foot tripped on a ring-bolt in the deck, and he fell heavily. His head struck with stunning force against a bulwark stanchion.

The collision scattered his wits, and Martin lay in the scuppers, blinking at the dancing lights before his eyes. In his ears was a great humming. Then, after a moment, the humming broke into parts and became a babel of shouts.
