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 grass or ground. But there was nothing. The heat droned in the hush of afternoon. There was not a breath of moving air. But there was danger—a saw-toothed sense of danger close behind his neck.

"Sipar!" he called in a tense whisper, "Watch out!"

The native stood motionless, unheeding, its eyeballs rolling up until there was only white, while the muscles stood out along its throat like straining ropes of steel.

Duncan slowly swiveled, rifle held almost at arm's length, elbows crooked a little, ready to bring the weapon into play in a fraction of a second.

Nothing stirred. There was no more than emptiness—the emptiness of sun and molten sky, of grass and scraggy bush, of a brown-and-yellow land stretching into foreverness.

Step by step, Duncan covered the hillside and finally came back to the place where the native squatted on its heels and moaned, rocking back and forth, arms locked tightly across its chest, as if it tried to cradle itself in a sort of illusory comfort.

The Earthman walked to the place where the Cytha had fallen and picked up, one by one, the bits of bleeding flesh. They had been mangled by his bullet. They were limp and had no shape. And it was queer, he thought. In all his years of hunting, over many planets, he had never known a bullet to rip out hunks of flesh.

He dropped the bloody pieces back into the grass and wiped his hand upon his thighs. He got up a little stiffly.

He'd found no trail of blood leading through the grass, and surely an animal with a hole of that size would leave a trail.

And as he stood there upon the hillside, with the bloody fingerprints still wet and glistening upon the fabric of his trousers, he felt the first cold touch of fear, as if the fingertips of fear might momentarily, almost casually, have trailed across his heart.
