He saw the sealmen first. Some were quite close, but in the murk he had missed them. Silent specters, they were apparently lifeless, strewn all around at different levels, and most of them floating slowly up toward the dim ice ceiling.
But up under the ice was movement! Living figures were there! And at the sight Kenneth Torrance's lips spread in their first real grin for days. The plan had worked! The sealmen had been destroyed, and already some of the Peary's men were up there and fumbling clumsily across the hundred feet which separated them from the hole in the ice that was the last step to the world above.
A ghostly gray haze of light filtered downward through the water from the hole. Ken counted twelve figures making their way to it. As he wondered about the rest of the crew, he saw three bulging, swaying shapes suddenly emerge from the split in the top of the Peary, and begin an easy rise toward the ice ceiling ninety feet above. There was no apparent danger, and they went up quite slowly, with occasional brief pauses to avoid the risk of the bends. Clasped together, the group of three were, and when they were halfway to the glassy ceiling of the ice, three more left the rent in the submarine and followed likewise. Twelve men were at the top; six others were swimming up; three more were yet to leave the submarine—and after they had abandoned her, he, Ken, would follow with the torpoon and the food it contained.
So he thought, watching from where he lay, down below, and there was in him a great weariness after the triumph so bitterly fought for had been achieved. He rested through minutes of quiet and relaxation, watching what he had brought about; but only minutes—for suddenly without warning all security was gone.
From out the murky shadows to the left a sleek shape came flashing with great speed, to jerk Ken Torrance's eyes around and to widen them with quick alarm.
A sealman! A sealman alive, and moving—and vengeful! A sealman which the explosion of nitromite had not reached!
Doubtless the lone creature was surprised upon seeing all its fellows motionless, drifting like corpses upward, and the men of the Peary escaping. With graceful, beautiful speed, a liquid streak, it flashed into the scene, eeling up and around and down, trying to understand what extraordinary thing had happened. But finally it slowed down and hovered some thirty feet directly above the dark hull of the Peary.
The men rising toward the ice had seen the sealman at the same time Ken Torrance had, and at once increased their efforts, fearing immediate attack. Quickly the two groups shot to the top where the other twelve were, and began a desperate fumbling progress over toward the hole that alone gave exit. But the sealman paid no attention to them. It was looking at something below.
Ken saw what it was.
