Tortha Karf was silent for a while, after Verkan Vall had finished.

"You're taking some awful chances, Vall," he said, at length. "The way you plan doing it, the advantages will all be with the nighthound. Those things can see as well at night as you can in daylight. I suppose you know that, though; you're the nighthound specialist, now."

"Yes. But they're accustomed to the Venus hotland marshes; it's been dry weather for the last two weeks, all over the northeastern section of the Northern Continent. I'll be able to hear it, long before it gets close to me. And I'll be wearing an electric headlamp. When I snap that on, it'll be dazzled, for a moment."

"Well, as I said, you're the nighthound specialist. There's the communicator; order anything you need." He lit a fresh cigarette from the end of the old one before crushing it out. "But be careful, Vall. It took me close to forty years to make a paratimer out of you; I don't want to have to repeat the process with somebody else before I can retire."


The grass was wet as Verkan Vall—who reminded himself that here he was called Richard Lee—crossed the yard from the farmhouse to the ramshackle barn, in the early autumn darkness. It had been raining that morning when the strato-rocket from Dhergabar had landed him at the Hagraban Synthetics Works, on the First Level; unaffected by the probabilities of human history, the same rain had been coming down on the old Kinchwalter farm, near Rutter's Fort, on the Fourth Level. And it had persisted all day, in a slow, deliberate drizzle.

He didn't like that. The woods would be wet, muffling his quarry's footsteps, and canceling his only advantage over the night-prowler he hunted. He had no idea, however, of postponing the hunt. If anything, the rain had made it all the more imperative that the nighthound be killed at once. At this season, a falling temperature would speedily follow. The nighthound, a creature of the hot Venus marshes, would suffer from the cold, and, taught by years of domestication to find warmth among human habitations, it would invade some isolated farmhouse, or, worse, one of the little valley villages. If it were not killed tonight, the incident he had come to prevent would certainly occur.

Going to the barn, he spread an old horse blanket on the seat of the jeep, laid his rifle on it, and then backed the jeep outside. Then he took off his coat, removing his pipe and tobacco from the pockets, and

spread it on the wet grass. He unwrapped a package and took out a small plastic spray-gun he had brought with him from the First Level, aiming it at the coat and pressing the trigger until it blew itself empty. A sickening, rancid fetor tainted the air—the scent of the giant poison-roach of Venus, the one creature for which the nighthound bore an inborn, implacable hatred. It was because of this compulsive urge to attack and kill the deadly poison-roach that the first human settlers on Venus, long millennia ago, had domesticated the ugly and savage nighthound. He remembered that the Gavran family derived their title from their vast Venus hotlands estates; that Gavran Sarn, the man who had brought this thing to the Fourth Level, had been born on the inner planet. When Verkan Vall donned that coat, he would become his own living bait for the murderous fury of the creature he sought. At the moment, mastering his queasiness and putting on the coat, he objected less to that danger than to the hideous stench of the scent, to obtain which a valuable specimen had been sacrificed at the Dhergabar Museum of Extraterrestrial Zoology, the evening before.

Carrying the wrapper and the spray-gun to an outside fireplace, he snapped his lighter to them and tossed them in. They were highly inflammable, blazing up and vanishing in a moment. He tested the electric headlamp on the front of his cap; checked his rifle; drew the heavy revolver, an authentic product of his line of operation, and flipped the cylinder out and in again. Then he got into the jeep and drove away.
