Philadelphia, while grubbing inside a broken store window that he had discovered another symptom of his change. The jagged glass pane had ripped the shirt through to his skin—but had not damaged him. The flesh showed white momentarily, and then even that faded. Seligman experimented cautiously, then recklessly, and found that the radiations, or his treatments, or both, had indeed changed him. He was completely impervious to harm of a minor sort: fire in small amounts did not bother him, sharp edges could no more rip his flesh than they could a piece of treated steel, work produced no callouses; he was, in a limited sense of the word, invulnerable. The indestructible man had been created too late. Too late to bring satisfaction to the myopic butchers who had puttered unceasingly about his body. Perhaps had they managed to survive they might still not comprehend what had occurred. It was too much like the product of a wild coincidence. But that had not lessened his agony.

He smiled a tight, grim smile as he thought: At least I won't have to carry a lantern to them; they'll see me coming by my own glow. Glow little glow worm, glimmer, glimmer.... Seligman threaded his way through the tortured wreckage and crumpled metalwork of what had been a towering structure of shining-planed glass and steel and plastic. Even though he knew he was alone, Seligman turned and looked back over his shoulder, sensing he was being
