The seal-men passed by--two sleek, blubbery shapes, flipper-arms and legs weaving gracefully, bodies rolling slightly, eyes apparently directed ahead. Close! They had escaped that time, but there was a disturbing thought in Ken's mind and in Beddoes' too, perhaps--as they resumed their slow-motion flight down the second corridor. "What if those two were going to visit us in the cell-chamber? Once they see the dead guard, hell sure will start to pop!" For a period that seemed to be measured in hours they fought their way forward through the retarding pressure of the water. The corridor described a long curve. They were on the last stretch--and still no pursuit! "If only the torp's there!" Ken kept exclaiming in his thoughts. "Just that!" "If only the torp's there!..." Had they come the right way? He had to trust that to the memory of Beddoes. Beddoes, whose mind had clearly been affected by his seven-day nightmare.... He shook his head. He dared not doubt. They increased their pace a little. Imagination stimulated their weary muscles. The _Narwhal_! Men of their own kind! Sun and air! Life again! Ken could have shouted when he saw his partner stop and gesture excitedly before a dark spot in the wall. It could be nothing but the entrance to a trap. He pressed forward, flicking on his flash and making sure by the water-waved beam it threw. But Beddoes was attending to some sight down the corridor; and suddenly he pointed in fright. The first torpooner looked in the indicated direction and saw what was meant. Approaching was a wave of menacing brown-skinned bodies, streaming swiftly through the passage several abreast. Their escape had been discovered. The blubber-men were coming. At once Ken acted, pushing Chan into the narrow opening and scrambling after himself. They wormed along for several feet, till they emerged in a large dark chamber at the far end of which was a big circular entrance barred by three great pale stakes. They were certainly in a whale trap. Rapidly Ken played his flash around, looking for the torp, but it was nowhere visible. To one side was an out-jutting rock with a niche beneath it. It was a promising place and he stumbled his way there, followed by the other. It was then that a most peculiar feeling came over him, a feeling that was instantly a surge of panic. Something else was in the trap! His flash arced around and up, and what lay revealed in its ray caused cold shivers to run down the backs of the two men. Above them, just over the three-toothed outer entrance, hung a black, sleek body, white-striped. Head-on it was, and motionless, eyeing them. A killer whale--alive!--and poised for a lunge! It barred the way to the outer entrance. They could not retrace their steps; already the round brown head of a blubber-men showed in the inner entrance. They were trapped, front and rear, and confronted by the deadliest animal in the sea.
