A scream, filled with all the agony of a man in torment, caught up on the echoes of that other cry. Vye sighted a wild waving of bushes. A figure, very small and far away, crawled into the open on hands and knees and then crumpled into only a shadowy blot on the moss. Again the beast's cry, and a shouting! Vye watched a second man back out of the trees, still facing whatever pursued him. He caught the glint of sun on what must be a ray tube. Leaves crisped into a black hole, curls of smoke arose along the path of that blast. The man kept on backing, passed the inert body of his companion, glancing now and then over his shoulder at the slope up which he was making a slow but steady way. He no longer rayed the bush, but there was the crackle of a small fire outlining the ragged hole his beam had cut. Back two strides, three. Then he turned, made a quick dash, again facing around after he had gained some yards in the open. Vye saw now it was Wass. Another dash and an about face. But this time to confront the enemy. There were three of them, as monstrous as those Vye and Hume had fought in the same place. And one of them was wounded, swinging a charred forepaw before it, and giving voice to a wild frenzy of roars. Wass leveled the ray tube, centered sights on the beast nearest to him. The man hammered at the firing button with the flat of his other hand, and almost paid for that second of distraction with his life, for the creature made one of those lightning swift dashes Vye had so luckily escaped. The clawed forepaw tore a strip from the shoulder of Wass' tunic, left sprouting red furrows behind. But the man had thrown the useless tube into its face, was now running for the gap. Vye held the needler braced against his knee to fire. He saw the dart quiver in the upper arm of the beast, and it halted to pull out that sliver of dangerously poisoned metal, crumpled it into a tight twist. Vye continued to fire, never sure of his aim, but seeing those slivers go home in thick legs, in outstretched forelimbs, in wide, pendulous bellies. Then there were three blue shapes lying on the slope behind the man running straight for the gap. Wass hit the invisible barrier full force, was hurled back, to lie gasping on the turf, but already raising himself to crawl again to the gateway he saw and could not believe was barred. Vye closed his eyes. He was very tired now--tired and sleepy--maybe the pain pills were bringing the secondary form of relief. But he could hear, just beyond, the man who beat at that unseen curtain, first in anger and fear, and then just in fear, until the fear was a lonesome crying that went on and on until even that last feeble assault on the barrier failed. * * * * * "We have here the tape report of Ras Hume, Out-Hunter of the Guild." Vye watched the officer in the black and silver of the Patrol, a black and silver modified with the small, green, eye badge of X-Tee, with level and hostile gaze.
