there were sounds of movement, the low staccato chatter of typers, occasional bits of conversation, and the hum of electronic equipment. Forsythe was impressed, though not a line on his face showed it. The office to which he had been assigned was lined with electronic calculators, and his name had already been put on the door in gold. It was to his credit that he was impressed by the two factors in that order. In the rear of the room, two technicians were working on an open panel in one of the units. Nearby, a dark-haired, dark-eyed, maturely handsome woman in her early thirties was holding a clip board and making occasional notes as the men worked.

"Oh, yes, certainly," Forsythe said hurriedly. "We are attempting to determine whether the actions of human beings can actually have any effect on the outcome of the prophecy itself. In other words, if it is possible to avert, say, a disaster if it is foretold, or whether the very foretelling itself
