We crossed the foothills and began to climb upward toward the mountains. The first few days I found myself short of breath as we worked upward into thinner air, then my acclimatization returned and I began to fall into the pattern of the days and nights on the trail. The Trade City was still a beacon in the night, but its glow on the horizon grew dimmer with each day's march. Higher we climbed, along dangerous trails where men had to dismount and let the pack animals pick their way, foot by foot. Here in these altitudes the sun at noonday blazed redder and brighter, and the Dry-towners, who come from the parched lands in the sea-bottoms, were burned and blistered by the fierce light. I had grown up under the blazing sun of Terra, and a red sun like Wolf, even at its hottest, caused me no discomfort. This alone would have made me suspect. Once again I found Cuinn's fierce eyes watching me. As we crossed the passes and began to descend the long trail through the thick forests, we got into nonhuman country. Racing against the Ghost Wind, we skirted the country around Charin, and the woods inhabited by the terrible Ya-men, birdlike creatures who turn cannibal when the Ghost Wind blows. Later the trail wound through thicker forests of indigo trees and grayish-purple brushwood, and at night we heard the howls of the catmen of these latitudes. At night we set guards about the caravan, and the dark spaces and shadows were filled with noises and queer smells and rustlings. Nevertheless, the day's marches and the night watches passed without event until the night I shared guard with Cuinn. I had posted myself at the edge of the camp, the fire behind me. The men were sleeping rolls of snores, huddled close around the fire. The animals, hobbled with double ropes, front feet to hind feet, shifted uneasily and let out long uncanny whines. I heard Cuinn pacing behind me. I heard a rustle at the edge of the forest, a stir and whisper beyond the trees, and turned to speak to him, then saw him slipping away toward the outskirts of the clearing. For a moment I thought nothing of it, thinking that he was taking a few steps toward the gap in the trees where he had disappeared. I suppose I had the idea that he had slipped away to investigate some noise or shadow, and that I should be at hand. Then I saw the flicker of lights beyond the trees--light from the lantern Cuinn had been carrying in his hand! He was signaling! I slipped the safety clasp from the hilt of my skean and went after him. In the dimming glow of the fire I fancied I saw luminous eyes watching me, and the skin on my back crawled. I crept up behind him and leaped. We went down in a tangle of flailing legs and arms, and in less than a second he had his skean out and I was gripping his wrist, trying desperately to force the blade away from my throat. I gasped, "Don't be a fool! One yell and the whole camp will be awake! Who were you signaling?"
