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.
