that he had located it, he could distinguish its outline with the naked eye. His hand reached out and slid the rifle to him. He fitted it to his shoulder and wriggled his body for closer contact with the ground. The cross-hairs centered on the faint outline on the knoll and then the beast stood up. It was not as large as he had thought it might be—perhaps a little larger than Earth lion-size, but it certainly was no lion. It was a square-set thing and black and inclined to lumpiness and it had an awkward look about it, but there were strength and ferociousness as well. Duncan tilted the muzzle of the rifle so that the cross-hairs centered on the massive neck. He drew in a breath and held it and began the trigger squeeze. The rifle bucked hard against his shoulder and the report hammered in his head and the beast went down. It did not lurch or fall; it simply melted down and disappeared, hidden in the grass. "Dead center," Duncan assured himself. He worked the mechanism and the spent cartridge case flew out. The feeding mechanism snicked and the fresh shell clicked as it slid into the breech. He lay for a moment, watching. And on the knoll where the thing had fallen, the grass was twitching as if the wind were blowing, only there was no wind. But despite the twitching of the grass, there was no sign of the Cytha. It did not struggle up again. It stayed where it had fallen. Duncan got to his feet, dug out the bandanna and mopped at his face. He heard the soft thud of the step behind him and turned his head. It was the tracker. "It's all right, Sipar," he said. "You can quit worrying. I got it. We can go home now." t had been a long, hard chase, longer than he had thought it might be. But it had been successful and that was the thing that counted. For the moment, the vua crop was safe. He tucked the bandanna back into his pocket, went down the slope and started up the knoll. He reached the place where the Cytha had fallen. There were three small gouts of torn, mangled fur and flesh lying on the ground and there was nothing else. He spun around and jerked his rifle up. Every nerve was screamingly alert. He swung his head, searching for the slightest movement, for some shape or color that was not the shape or color of the bush or
