Bill caught one of its legs and instantly it coiled back upon itself and fastened its fanged mouth upon his forearm. Only the invulnerable Beryllium mesh saved it from being fanged through; as it was, the awful pressure of those inhuman teeth was excruciating agony. In desperation Bill aimed another slashing blow at the maniacal face of the being, and saw it become indistinct with blood; using every ounce of strength at his command, the Earthman slowly forced back the face of the thing and with a convulsive movement shattered its vertebrae. When Bill released it, the creature dropped limp on the bloodied translucence of the Jadite flooring. Reeling from fatigue, his body a mass of bruises, Bill methodically examined his attacker. It was about four feet tall, humanoid in shape, even as to features which were delicate--surprisingly beautiful in the repose of death. It had the face of a very beautiful woman in miniature. But there was nothing lovely about the competent taloned hands with their cording of steely muscles, or about the oddly shaped flexible feet--almost hands in themselves, like that of the now extinct apes of thousands of years back when Terra had been young. The body had evidently been evolved with a great simplicity of purpose--and, strangest of all, it was sexless! And this was the thing that had been able to penetrate the defenses of his mind, almost succeeding in probing it without Bill being aware of it. In coordinating his findings, it occurred to Bill Nardon that this unholy creature was the nearest thing to a _homunculi_ he had ever known! But whence had it come? How correlate such a _mind of power_ with such utterly ruthless, coldly calculating ferocity. Bill shivered a little, and it was not altogether from his recent exertions in defense of his life. Stretched upon the exquisite whiteness of the plastic Jadite flooring, there was an infinitely appealing beauty to its face in the ultimate sleep, as if it were a welcome repose. The light brown eyes still open mirrored sadness--that was the incredible fact. The mind that had tip-toed the shores of his consciousness with sandals of foam, was still. But Bill Nardon's mind recovered from the horror of the unexpected attack, felt even more the icy chill of failure as it sought factors and only found an impenetrable mystery instead.
