president of Dartmouth Bearing Corporation.... He found a small, wooded glade not far from the Library, and set the 'copter down skillfully, his mind numbed, fighting to see through the haze to the core of incredible truth he had uncovered. The great, jagged piece, so long missing, was suddenly plopped right down into the middle of the puzzle, and now it didn't fit. There were still holes, holes that obscured the picture and twisted it into a nightmarish impossibility. He snapped the telephone switch, tried three numbers without any success, and finally reached the fourth. He heard Dr. Prex's sharp voice on the wire. "Anything happen since I left, Prex?"

Shandor settled back, staring dully at the ground moving below him, the whisps of evening haze rising over the darkening land. There was only one thing to do. He had to have Ingersoll's files. He knew only one way to get them. Half an hour later he was settling the ship down, under cover of darkness, on the vast grounds behind the Ingersoll estate, cutting the motors to effect a quiet landing. Tramping down the ravine toward the huge house, he saw it was dark; down
