Wisconsin. They didn't even know that she was not a native. She never That was back in '07, on the eve of his departure for Alpha Centaurus but she never spoke of this and she was very careful not to move from "There goes one of the old-fashioned ones. That hair-do was popular back in the sixties." They did not suspect that she did this only to cover the thin, pencil-line scar, evidence that a small cylinder lay under her skin behind the ear. Her husband had been one of the small group who developed this tiny 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. Several times in the past seven years Mrs. Jamieson had seen other Konvs, and had been tempted to identify herself and say, "Here I am. while her husband had been one of twenty-eight persons. She decided then that her efforts would be too ineffective. The odds were wrong. She would wait until her son, Earl, was grown. Together they would seek revenge. He did not have the cylinder—not 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 violently, so that she was forced to slap him to prevent hysteria. She looked behind his ear. Apparently they did not miss him. Mrs. Jamieson handed him a pair of trousers. "Here, get yourself dressed. Then we'll talk." "What?" "Never mind. What happened just now?" unusual and terrible to think of at first, but really wonderful." "But what happened? What is this patch behind my ear?" trousers. "Guess I know now. They made me a Konv." also our side." He turned back, a dawning comprehension showing in his eyes. "That's "I saw you. I wasn't sleeping. I was afraid to stay inside alone, so I followed you. I never told anyone." "But you were only nine!" "They would have taken you away if I'd said anything." Mrs. Jamieson held out her hand. "Come here, son. It's time I told you about us." So he sat across the kitchen table from her, and she told the whole history, beginning with Stinson sitting in the laboratory in New Jersey, holding in his hand a small cylinder moulded from silicon Then he made more cylinders. He was the only man in the world who knew how to construct it, and he kept the secret, giving cylinders to selected people. He worked out the basic principle, calling it a reason for noticing them at all was lost. Normal men no longer thought of them as human. Mrs. Jamieson told how Stinson, knowing he had made too many cylinders and given them unwisely, left Earth for Alpha Centaurus. 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 died. Now I will tell you the truth. Your father was one of the great you couldn't do them?" Just like that, it was over. That is, the first shock was over. Mrs. Jamieson watched Earl leave the For the remainder of that summer they worked together. They practiced at night mostly, taking longer and longer jumps, until Earl's 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 for some clue to their identity. It was inevitable that they should identify Mrs. Jamieson as one of Konvs when he left Earth, leaving all those with criminal tendencies "Remember who you are.

She never tired of discussing them. She would tell about Benjamin's wife, Lisa, and try to describe the horror in Lisa's young mind when the news went out that E. Mason Jamieson had been killed. She wanted him to learn as much as possible about his father's death, knowing that soon the Agents would would learn it faster if she avoided the word. The winter passed, and the next summer, and two more summers. Earl was ready for college. They had successfully kept their secret. contacting other Konvs, and sometimes visited them at a remote rendezvous. "When you have finished college," Mrs. Jamieson told her son, "we will go to Centaurus." "Why not now?" "Because when you get there they will need men who can contribute to He shook his head again.

"You understand what I'm saying, don't you?" You are a Konv. You always will be a Konv. Have you forgotten your own father? " Earl did not use the room that first year. He slept in the second 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. long convalescence.

"And you believed him?" Beyond the closed door, out of sight of her son, Mrs. Jamieson gave rein to the excitement that ran through her. He had wanted the names! He didn't know why—not yet—but he would. "He'll do it yet!" she years they might be scattered all over Earth. In the killing of Konvs, cylinder and were now Konvs themselves.

"I remember when you were born," he said, and smiled in reminiscence. "Your father was afraid you would be twins." Love, Benjamin said, the greatest of these is love. Or did someone else say that?
