He gave himself time for a glance out over the still water. The black fin was there, yes, but not too perilously near, he thought--maybe a hundred yards off, and moving away, cutting the water slowly astern of the _Diana_. The small commotion of the monkey's fall must have gone unnoticed, or the shark would have had her in an instant. Ben gave himself time for one other glance, backward. Marsh had no knife. Dummy's chest was dripping blood, but the knife lay several feet away. Dummy was over Marsh, a knee on his chest, one fearsome hand closed around his throat, and Marsh was not struggling. His neck was probably broken already; the black eye-patch dangled over his ear; neither eye would see anything more, and the smile was gone. Joey Mills inside the rail was chattering. "Don't dive, Ben, for God's sake don't! Leave me throw the brute a rope." He had one in his quick little hands, had made it fast to the rail. "Don't heave it, Joey--let it down." Ben could make out the shoe-button dots of eye. They were fixed and possibly blind. "She could never find it," Ben said. The motion of her arms had almost ceased; she could make no progress through the water. Ben caught the rope and let himself down without a splash, gauged his distance from her, and struck out under water, eyes open. He found the black shadow of her body and emerged beside her, about to reach for her, but she had life enough yet to grab at him. He turned his head to save his eyes. He felt the clutch of midget fingers in his hair, the scrabble of her legs at his shoulders, and he swam for his life. Ledyard's wild yell aided him. Until he caught the noise of it he had been concerned only with his need to complete the act, having no time at all to be afraid. The yell brought him sharp knowledge of death, and the one more ounce of speed required to defeat it. He found and seized the rope, and swung with a final burst of violence into safety. Up here in his own element, clutching the rail with Dummy's monkey secure in his other arm, he could look down in time to see not only the black fin lancing toward him from astern but another shape of the same breed, a vast gray hunger shimmering upward from the abyss, shifting to dull silver, cutting water harmlessly at the _Diana's_ side and surging unappeased away. Dummy stumbled over the deck bleeding from the long gash across his ribs. He blinked in love and fear at the naked god and fell to his knees, then forward to clasp Ben's foot and roll his forehead over it.
