Below them in the bowl of the ship were those who would not know the end consciously....save in one compartment. In a padded cage a prick-eared head stirred where it rested on forepaws, slitted eyes blinked, aware not only of familiar surroundings, but also of the tension and fear generated by human minds and emotions levels above. A pointed nose raised, and there was a growling deep in a throat covered with thick buff-gray hair.

The growl aroused another similar captive. Knowing yellow eyes met yellow eyes. An intelligence, which was certainly not that of the animal body which contained it, fought down instinct raging to send both those bodies hurtling at the fastenings of the twin cages. Curiosity and the ability to adapt had been bred into both from time immemorial. Then something else had been added to sly and cunning brains. A step up had been taken....to weld intelligence to cunning, connect thought to instinct.

More than a generation earlier mankind had chosen barren desert....the "white sands" of New Mexico....as a testing ground for atomic experiments. Humankind could be barred, warded out of the radiation limits; the natural desert dwellers, four-footed and winged, could not be so controlled.

For thousands of years, since the first southward roving Amerindian tribes had met with their kind, there had been a hunter of the open country, a smaller cousin of the wolf, whose natural abilities had made an undeniable impression on the human mind. He was in countless Indian legends as the Shaper or the Trickster, sometimes friend, sometimes enemy. Godling for some tribes, father of all evil for others. In the wealth of tales the coyote, above all other animals, had a firm place.

Driven by the press of civilization into the badlands and deserts, fought with poison, gun, and trap, the coyote had survived, adapting to new ways with all his legendary cunning. Those who had reviled him as vermin had unwillingly added to the folklore which surrounded him, telling their own tales of robbed traps, skillful escapes. He continued to be a trickster, laughing on moonlit nights from the tops of ridges at those who would hunt him down.

Then, close to the end of the twentieth century, when myths were scoffed at, the stories of the coyote's slyness began once more on a fantastic scale. And finally scientists were sufficiently intrigued to seek out this creature that seemed to display in truth all the abilities credited to his immortal namesake by pre-Columbian tribes.

What they discovered was indeed shattering to certain closed minds. For the coyote had not only adapted to the country of the white sands; he had evolved into something which could not be dismissed as an animal, clever and cunning, but limited to beast range. Six cubs had been brought back on the first expedition, coyote in body, their developing minds different. The grandchildren of those cubs were now in the ship's cages, their mutated senses alert, ready for the slightest chance of escape. Sent to Topaz as eyes and ears for less keenly endowed humans, they were not completely under the domination of man. The range of their mental powers was still uncomprehended by those who had bred, trained, and worked with them from the days their eyes had opened and they had taken their first wobbly steps away from their dams.
