For the thing in the forest, the creature half-human, half-beast, had raised its two shaggy arms before it; and, with eyes fixed and staring, it was walking straight toward them, walking as no other living thing had walked, but one. Chet was seeing again that one--a helplessly hypnotized ape that appeared from a pit in a great pyramid. And the voice within him repeated hopelessly: "They have found you. They have run you down." Chet lay motionless. He still hoped that the dread messenger might pass them by, but the rigidly outstretched arms were extended straight toward him; the creature's short, heavily muscled legs were moving stiffly, tearing a path through the thick grass and bringing him nearer with every step. * * * * * Diane and Harkness had been a few paces in advance of Chet when they dropped into the concealing grass. Chet could see where they lay, and the ape-man, as he approached, turned off as if he had lost the direction. He passed Chet by, passed where Walt and Diane were hiding and stopped! And Chet saw the glazed eyes turn here and there about their peaceful valley. Unseeing they seemed, but again Chet knew better. Was he more sensitively attuned than the others? Who could say? But again he caught a message as plainly as if the words had been shouted inside his brain. "Yes, the valley of the three sentinel peaks and the lake of blue; we can find it again. Houses, shelters--how crudely they build, these white-faced intruders!" Chet even sensed the contempt that accompanied the thoughts. "That is enough; you have done well. You shall have their raw hearts for your reward. Now bring them in--bring them in quickly!" The instant action that followed this command was something Chet would never have believed possible had his own eyes not seen the incredible leap of the huge body. The ape-man's knotted muscles hurled him through the air directly toward the spot where Walt and Diane were hidden. But, had Chet been able to stand off and observe himself, he might have been equally amazed at the sight of a man who leaped erect, who raised a long bow, fitted an arrow, drew it to his shoulder, and did all in the instant while the huge brute's body was in the air. The great ape landed on all fours. When he straightened and stood erect--his arms were extended, and in each of his gnarled hands he held a figure that was helpless in that terrible grasp. No chance to loose the arrow then, though the brute's back was half turned. He had Harkness and Diane by their throats, and Chet knew by the unresisting limpness of Harkness' body that the fearful fire in those blazing eyes had them in a grip even more deadly than the hands of the beast. * * * * * Thoughts were flashing wildly through Chet's brain. "Knocked 'em cold! He'll do the same to me if I meet his eyes. But I can't shoot now; Diane's in line. I must take him face about; get him before he gets me--get him first time!"
