at the center of a mare on the always hidden hemisphere of the Moon. "Mitch knows what he wants and is direct about it," was Jack Dukas's comment. "Simple. No conflicts. The scientist's approach. Wise or stupid? Who knows?" Eddie was six, and then seven. The years moved slowly, but he grew and hardened with them. By the time he was twelve, sports and study and awareness of realities had toughened his body and matured his soul considerably. That was fortunate, for this was his and mankind's fateful year. The day came when the household robots were fixing up the guestroom specially for Uncle Mitch again. Dad was afield, a hundred miles away, to look over a vein of quartz crystal that was to be shipped to the lunar laboratories. At 9:00 P.M. Eddie's father had not yet returned. Eddie was sprawled on his bed looking lazily at the translucent blue font of the lamp beside it. The color was rich and beautiful, the carvings snaky and odd. Here was another gift, ordered by Uncle Mitch from a friend in the region of the Asteroids.

He was also thinking of neighborhood pals, to whom he had bragged about his uncle and his expected arrival. As for what happened at that moment: there was transpatial warning, radioed out fifteen seconds ahead, telling of forces gone hopelessly out of control in the lunar laboratories. But Eddie's set was not functioning, and he did not hear it. Beyond the windows of his room there was just calm, pale moonlight. The Moon looked little different than it always looked, except for the blue spots of the atmosphere domes of the great mining centers. But then came the intolerable blue-white light. Perhaps, somewhere, exposed instruments measured its intensity. On the roofs of meteorological stations, maybe. Say conservatively that, for the space of a few seconds, it was five hundred times as strong as full sunshine. Night was broken off. But there was no day like this. For one fragment of a second Eddie glanced at the window. Shadows seemed gone, utterly. Even dark things like tree trunks reflected so much light that they all but vanished in the shimmering glare. As yet, it was a
