unless it was relief from the tedium of ultra-civilized life. Hoddan's electronic device did not fill a human need; only a technical one. It had, therefore, no value that would make anybody hospitable to it. And Hoddan would spend his life in jail for failing to recognize the fact. He revolted, immediately. He wanted something! He wanted out. And because he was that kind of man he put his mind to work devising something he wanted, simply and directly, without trying to get it by furnishing other people with what they turned out not to want. He set about designing his escape. With his enforced change in viewpoint, he took the view that he must seem, at least, to give his captors and jailers and—as he saw it—his persecutors what they wanted. They would be pleased to have him dead, provided their consciences were clear. He built on that as a foundation. Very shortly before nightfall he performed certain cryptic actions. He unraveled threads from his shirt and put them aside. There would be a vision-lens in the ceiling of his cell, and somebody would certainly notice what he did. He made a light. He put the threads in his mouth, set fire to his mattress, and laid down calmly upon it. The mattress was of excellent quality. It would smell very badly as it smoldered. It did. Lying flat, he kicked convulsively for a few seconds. He looked like somebody who had taken poison. Then he waited.

His actions had been those of a man who'd anticipated a possible need to commit suicide, and who'd had poison in a part of his shirt for convenience. The jailer did not hurry, because if the inventor of a deathray committed suicide, everybody would feel better. Hoddan had been allowed a reasonable time in which to die. He seemed impressively dead when the jailer opened his cell door, dragged him out, removed the so-far-unscorched other furniture, and set up the fire hose to make an aerosol fog which would put out the fire. He went back to the corridor to wait for the fire to be extinguished. Hoddan crowned him with a stool, feeling an unexpected satisfaction in the act. The jailer collapsed. He did not carry keys. The system was for him to be let out of this corridor by a guard outside. Hoddan
