The rider was of medium size, with huge, strong hands and seemingly hollow eyes. Strange eyes, alive and aflame. They had no place in the dust-caked, tired body, yet there they were, seeking, always seeking—searching the clear horizon, and never seeming to find what they sought. The horse moved faster now. They were nearing a river the water would be welcome on tired bodies and dry throats. He spurred his horse, and when they reached the water's edge, he dismounted and unsaddled the horse. Then both man and horse plunged headlong into the waiting torrent, deep into the cool embrace of the clear liquid. They soaked it into their pores and drank deeply of it, feeling life going once more through their veins. Satisfied, they lifted themselves from the water, and the man lay down on the yellow sand of the river bank to sleep. the coffee he had found in one of the ruined cities. He brought water from the river in the battered coffee-pot he had salvaged, and while he waited for it to boil, he went to his horse, Conqueror, stroking his mane and whispering in his ear. Then he led him silently to a grassy slope where he hobbled him and left him for the night. In the fading light, he ate the hard beef jerky and drank the scalding coffee. Refreshed and momentarily content, he sat staring into the at the wood in consuming embrace, taking all and returning nothing but It was the night before he was to go overseas. World War III had been declared, and he had enlisted, receiving his old rank of captain. He was with his wife in the living room of their home. They had put the children to bed—their sons—and now sat on the couch, watching the blazing fire. It was then that he had showed it to her. "I've got something to tell you, and something to show you." He had removed the box from his pocket and opened it. And heard her cry of surprised joy. voice which always seemed to send a thrill through his body. "It's for you so long as you wear it, I'll come back, even from the dead, if need be. Read the inscription." his and making him oblivious to everything except that she was there in in one side, and in the other a picture of the children. He took her in The next morning had been bleak and gray. The mist clung to the wet, sodden ground, and the air was heavy in his lungs. He had driven off in the jeep the army had sent for him, watching her there on the porch until the mist swirled around her feet and she ran back into the house blood in his veins. Three days later they had landed in Spain, merged with another the threat of annihilation by the retaliation forces had been too great. He had done well in the war, and had been decorated many times for bravery in action. Now he felt the victory that seemed to be in the air, and he had wished it would come quickly, so that he might return to her. Home. The very feel of the word was everything a battle-weary soldier needed to make him fight harder and live longer. Suddenly he had become aware of a droning, wooshing sound above him. It targets. When the all-clear had sounded, the men clambered from their dust, their spirits fled on the winds to a new world. Yet these remnants of an army must return—or at least try. Their exodus was just beginning. Somehow he had managed to hold together the few men left from his force. He had always nourished the hope that she might still be alive. And now that the war was over he had to return—had to know whether she was still waiting for him. They had started the long trek. Throughout Europe anarchy reigned. He and his men were alone. All they could do now was fight. Finally they After months of storms and bad luck, they had been shipwrecked somewhere off the coast of Mexico. He had managed to swim ashore, and had been found by a fisherman's family. Many months he had spent swimming and fishing, recovering his strength, inquiring about the United States. The Mexicans had spoken with fear of the land across the had heard was the occasional swish of the wind as it whisked along what might have been dead leaves, but wasn't. He had been on the trail for a long time. His food was nearly exhausted. The mountains were just beginning, and he hoped to find food there. He had not found food, but his luck had been with him. He had found a horse. Not a normal horse, but a mutation. It was almost twice as large as a regular horse. Its skin seemed to shimmer and was like glassy steel to the touch. From the center of its forehead grew a horn, straight out, as the horn of a unicorn. But most startling of all were the animal's eyes which seemed to speak—a silent mental speech, which he could understand. The horse had looked up as he approached it and seemed to say: "Follow me." And he had followed. Over a mountain, until they came to a pass, and empty, but there were cans of food and a rifle and many shells. He had remained there a long time—how long he could not tell, for he could only measure time by the cycles of the sun and the moon. Finally he had taken the horse, the rifle and what food was left, and once again started the long journey home. The farther north he went, the more life seemed to have survived. He had seen great herds of horses like his own, stampeding across the plains, and strange birds which he could not identify. Yet he had seen no human beings. How, he did not know, for it was much changed. A sensing, perhaps, of what it had once been. He could not be more than two days' ride away. Once he was through this desert, he would find her, he would be with her once again all would be well, and his long journey would be over. The images faded. Even memory slept in a flow of warm blood. Body and mind slept into the shadows of the dawn. He awoke and stretched the cramped muscles of his body. At the edge of length of his frame. A deep ridge ran down the length of his torso, separating the muscles, making the chest broad. Well satisfied with his body, he plunged into the cold water, deep down, until he thought his then swiftly returned to the clean air, tingling in every pore. He dried himself and dressed. Conqueror was eating the long grass near the stream. Quickly he saddled him. No time for breakfast. He would ride all day and the next night. And he would be home. Still northward. The hours crawled slower than a dying man. The sun was a torch that pierced his skin, seeming to melt his bones into a streaming hair called stars. In the moonlight he had not seen the crater until he was at its very edge. Even then he might not have seen it had not the horse stopped suddenly. The wind swirled through its vast emptiness, slapping his face with dusty hands. For a moment he thought he heard Then he saw her. She was sitting motionless in a straight wooden chair beside the He was turning wearily away from the window when the movement of the trying to decipher some inscription inside it. He knew then. He had come home. up at the night sky and trying to draw strength from the wind that passed over him. It was no use. There was no strength. Only fear—a He closed the locket and fastened the clasp, and hung it on the doorknob. It moved slowly in the wind, back and forth, like a pendulum. "Forever—forever. Only death is forever." He could have sworn he heard the words. He ran. Away from the house. To the large horse with a horn in the center of its forehead, like a unicorn. Once in the saddle, the spurt of strength left him. His shoulders slumped, his head dropped onto his chest. Conqueror trotted away, the sound of his hooves echoing hollowly in the vast emptiness.
