He shivered as a howl sounded loudly and echoed, bearing the age-old warning of a wolf pack, hungry and a-hunt. Ross had never heard that sound before, but his human heritage subconsciously recognized it for what it was--death on four feet. Similarly, he was able to identify the gray shadows slinking about the nearest trees, and his hands balled into fists as he looked wildly about him for some weapon. The bunk was under him and three of the four walls of the room enclosed him like a cave. But one of those gray skulkers had raised its head and was looking directly at him, its reddish eyes alight. Ross ripped the top blanket off the bunk with a half-formed idea of snapping it at the animal when it sprang. Stiff-legged, the beast advanced, a guttural growl sounding deep in its throat. To Ross the animal, larger than any dog he had even seen and twice as vicious, was a monster. He had the blanket ready before he realized that the wolf was not watching him after all, and that its attention was focused on a point out of his line of vision. The wolfs muzzle wrinkled in a snarl, revealing long yellow-white teeth. There was a singing twang, and the animal leaped into the air, fell back, and rolled on the ground, biting despairingly at a shaft protruding from just behind its ribs. It howled again, and blood broke from its mouth. Ross was beyond surprise now. He pulled himself together and got up, to walk steadily toward the dying wolf. And he wasn't in the least amazed when his outstretched hands flattened against an unseen barrier. Slowly, he swept his hands right and left, sure that he was touching the wall of his cell. Yet his eyes told him he was on a mountain side, and every sight, sound, and smell was making it real to him. Puzzled, he thought a moment and then, finding an explanation that satisfied him, he nodded once and went back to sit at ease on his bunk. This must be some superior form of TV that included odors, the illusion of wind, and other fancy touches to make it more vivid. The total effect was so convincing that Ross had to keep reminding himself that it was all just a picture. The wolf was dead. Its pack mates had fled into the brush, but since the picture remained, Ross decided that the show was not yet over. He could still hear a click of sound, and he waited for the next bit of action. But the reason for his viewing it still eluded him. A man came into view, crossing before Ross. He stooped to examine the dead wolf, catching it by the tail and hoisting its hindquarters off the ground. Comparing the beast's size with the hunter's, Ross saw that he had not been wrong in his estimation of the animal's unusually large dimensions. The man shouted over his shoulder, his words distinct enough, but unintelligible to Ross.
