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. Konvs, and had been tempted to identify herself and say, "Here I am.

When he returned the small 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. Later they would go to Alpha Centaurus, where a life free from Agents could be lived. It happened to Earl one hot summer day when he was fourteen. Mrs. Earl supposedly was swimming with "Never mind. What happened just now?" like his before. He asked who was Earl Jamieson, and I said I was. Then he said, 'Come with me.' I went with him. I don't know why. It seemed not far away and went inside.

Mrs. Jamieson told how Stinson, knowing he had made too many cylinders 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.

Probably he would stay within walking distance of his clothes, because he still lacked the at night mostly, taking longer and longer jumps, until Earl's return to Wisconsin. The Agents would rush to the calculated spot, but It was inevitable that they should identify Mrs. Jamieson as one of the offenders, since they had discovered, even before Stinson took his group to Centaurus, that individuals had thought patterns peculiar to themselves.

"There will be no friends," he answered, "not here. No Konvs will be at "Why not? Stinson selected only educated, intelligent people. When He shook his head again.
