Mrs. Jamieson and her son were very comfortable, even in the coldest spoke of it, except at first, when Earl was a boy of seven and they had his name was Stinson, and the effects produced by it were known as the Stinson Effect. In appearance it resembled a small semi-conductor device. Analysis by the best scientific minds proved it to be a semi-conductor. Yet it held the power to move a body instantly from one point in space to any other point. Each unit was custom built, keyed to operate only by the thought pattern of the particular individual. stayed in one of her cabins. She learned that he was an Agent completely by accident. While cleaning the cabin one morning his badge fell out of a shirt pocket. She stood still, staring at the horror of it there on the floor, the shirt in She would wait until her son, Earl, was grown. Her husband had been one of the first, and they would not forget. One day the boy would disappear for a few hours. When he returned the small patch of gauze would be behind his ear. She would shield him until the opening healed. Then no one would ever know, because now they could do it without leaving the tell-tale scar. Then they would seek revenge. It happened to Earl one hot summer day when he was fourteen. Mrs. nude. At sight of his mother his face paled and he began to shake violently, so that she was forced to slap him to prevent hysteria. She looked behind his ear. "Mom!" he cried. "Mom!" friends were still swimming in the river, with great noise and delight. Apparently they did not miss him. Mrs. Jamieson handed him a pair of trousers. "Here, get yourself dressed. Then we'll talk." He started for his room, but she stopped him. "No, do it right here. You may as well get used to it now." "Get used to what?" "To people seeing you nude." "What?" "Better put your trousers on," Mrs. Jamieson said. "It's something very unusual and terrible to think of at first, but really wonderful." trousers. "Guess I know now. They made me a Konv." "Well, don't take on so. You'll get used to it." "But they shouldn't have! They didn't even ask me!" He started for the door, but she called him back. "No, don't run away It was her turn to be surprised. "You knew about that?" "I saw you. I wasn't sleeping. I was afraid to stay inside alone, so I followed you. I never told anyone." Mrs. Jamieson held out her hand. "Come here, son. It's time I told you first. He felt the sand and water, and felt of himself there was no On the plane back to New Jersey he came to certain conclusions regarding the strange power of his device. He tried it again, secretly. knew how to construct it, and he kept the secret, giving cylinders to selected people. He worked out the basic principle, calling it a It was a subject of wonder and much speculation, but no one took serious notice of them until one night a federal Agent arrested one man for indecency. It was a valid charge. One disadvantage of this method of travel was that, while a body could travel instantaneously to any chosen spot, it arrived without clothes. The arrested man disappeared from his jail cell, and the next morning the Agent was found strangled to death in his bed. This set off a reason for noticing them at all was lost. Normal men no longer thought and given them unwisely, left Earth for Alpha Centaurus. He went alone, not knowing if he could go so far, or what he would find when he arrived. But he did arrive, and it was what he had sought. He returned for the others. They gathered one night in a dirty, broken-down farmhouse in Missouri—and disappeared in a body, leaving the Agents standing helplessly on Earth, shaking their fists at the sky. "You have asked many times," Mrs. Jamieson said, "how your father the escape but the Agents found him in Bangkok fifteen minutes before "I don't blame you, mother," Earl said simply. "But we are freaks. "Of course they do—because they don't understand! They are afraid of the initial shock wore off he might experiment with his new power. He would not travel far, in these first attempts. Probably he would stay within walking distance of his clothes, because he still lacked the tricks others had learned. It was a hot, mucky afternoon with storm clouds pushing out of the For the remainder of that summer they worked together. They practiced at night mostly, taking longer and longer jumps, until Earl's confidence allowed him to reach any part of the Earth he chose. She knew the habits of Agents. She knew how to avoid them. They would select a spot sufficiently remote to insure detection, she then they would quickly return to Wisconsin. The Agents would rush to the calculated spot, but would find only the bare footprints of a woman and a boy. They would swear and drive back to their offices to dig through files, searching for some clue to their identity. they said that Mrs. Jamieson had gone to Centaurus with the others. Had she returned to Earth? The question did not trouble them long. They had more serious problems. Stinson had selected only the best of the Konvs when he left Earth, leaving all those with criminal tendencies behind. They could have followed if they chose—what could stop them? But it was more lucrative to stay. On Earth they could rob, loot, even friends began to bore him. "Be careful, Earl," his mother would say. stand up and scream at her son, "Hate, hate! Hate!

He shook his head again. "Why can't I be in the house with you? There are two bedrooms." She said quickly, "You can if you wish. I just thought you'd like being alone, at your age. Most boys do." "I'm not like most boys, mother. The Konvs saw to that. Sometimes I'm "No, I don't!" she said sharply. "You're old enough to face realities. bedroom. He did not mention his frustrated desires to be normal, not after the first attempt, but he persisted in his efforts to be so. Use of the cylinder was out of the question for them now, anyway. thought he moved in an effort to please her because of the illness, but she soon grew aware of her mistake. One day he disappeared. When she arrived at her own home, Earl was in his room. bedclothes to a jealous lover listening at a keyhole. "Tom Palieu" didn't sound evil neither did "Al Jonson." She was shaken by this more "Why did you want the names?" arm. "Your father would have been proud of you," she said. "Soon you Beyond the closed door, out of sight of her son, Mrs. Jamieson gave He turned away from her. "It doesn't matter whether I did or not. They will suspect me. His name was on the list." So much strength and rage was in her arm that the blow almost sent him spinning. They faced each other, she breathing hard from the exertion, Earl stunned immobile—not by the blow, but from the knowledge that she that your father and I had a son. Your birth was recorded. The only She did not answer him. Finally he said, "It doesn't make sense to you, middle-aged man whose hair was completely white. He stood near the desk, easily, as if standing there were the most natural way to relax. He was entirely nude ... but it seemed natural and right. Then Mrs. Jamieson saw him. "Benjamin!" she cried. "I knew someone would come." "Your father was afraid you would be twins." one thought of hatred at them, but of course they did not hear her. Benjamin's hands gripped tightly. She was still in the room! Benjamin and her son were gone. Her outstretched hands touched nothing.
