The stranger was oddly dressed--too lightly dressed if one judged the climate by the frequent snow patches and the biting cold. A strip of coarse cloth, extending from his armpit to about four inches above the knee, was wound about his body and pulled in at the waist by a belt. The belt, far more ornate than the cumbersome wrapping, was made of many small chains linking metal plates and supported a long dagger which hung straight in front. The man also wore a round blue cloak, now swept back on his shoulders to free his bare arms, which was fastened by a large pin under his chin. His footgear, which extended above his calves, was made of animal hide, still bearing patches of shaggy hair. His face was beardless, though a shadowy line along his chin suggested that he had not shaved that particular day. A fur cap concealed most of his dark-brown hair. Was he an Indian? No, for although his skin was tanned, it was as fair as Ross's under that weathering. And his clothing did not resemble any Indian apparel Ross had ever seen. Yet, in spite of his primitive trappings, the man had such an aura of authority, of self-confidence, and competence that it was clear he was top dog in his own section of the world. Soon another man, dressed much like the first, but with a rust-brown cloak, came along, pulling behind him two very reluctant donkeys, whose eyes rolled fearfully at sight of the dead wolf. Both animals wore packs lashed on their backs by ropes of twisted hide. Then another man came along, with another brace of donkeys. Finally, a fourth man, wearing skins for covering and with a mat of beard on his cheeks and chin, appeared. His uncovered head, a bush of uncombed flaxen hair, shone whitish as he knelt beside the dead beast, a knife with a dull-gray blade in his hand, and set to work skinning the wolf with appreciable skill. Three more pairs of donkeys, all heavily laden, were led past the scene before he finished his task. Finally, he rolled the bloody skin into a bundle and gave the flayed body a kick before he ran lightly after the disappearing train of pack animals. CHAPTER 2 Ross, absorbed in the scene before him, was not prepared for the sudden and complete darkness which blotted out not only the action but the light in his own room as well. "What--?" His startled voice rang loudly in his ears, too loudly, for all sound had been wiped out with the light. The faint swish of the ventilating system, of which he had not been actively aware until it had disappeared, was also missing. A trace of the same panic he had known in the cockpit of the atomjet tingled along his nerves. But this time he could meet the unknown with action. Ross slowly moved through the dark, his hands outstretched before him to ward off contact with the wall. He was determined that somehow he would discover the hidden door, escape from this dark cell....
