throat. He moved through the large instrument chamber then and sat on the floor beside the cat. Then the flash went out and his laughter came again ... "All right, gentlemen, the time has come. In a few minutes an automatic control, synchronized with controls in the rocket will be set off in the main laboratory building. If we want to watch the launching we'll have to hurry." "A ll Fred Trent listened to the voice of Mathieson, and saw the famed American scientist start out of the central lobby toward the launching site. The gathered newspapermen followed, their voices filled with excitement now that the moment had come. Trent followed along with them, but felt a peculiar tenseness within him. He had been watching for Gaddon to make his appearance. But as yet the Englishman had not showed up. Was it possible that he wasn't going to watch the rocket launching? As Trent followed the others out into the gathering night, he frowned to himself. It was certainly strange. And entirely unlike the blustering manner Gaddon had displayed on the drive back from Tucson. Or had the man suddenly realized that he had made a fool of himself and was taking this easy way out? But that too didn't seem natural. And Trent found himself edging forward through the ranks of the newsmen, until he had reached the side of Mathieson. The scientist was talking to one of the journalists as they rounded the corner of the Administration building. Now the rockets were in sight, standing tall and immense in the shadows. Mathieson held his hand up in a gesture of halt, and the men behind him drew into a compact circle. Fred turned to Mathieson. "Dr. Mathieson, isn't Dr. Gaddon going to be here for the launching?" The head of the rocket project turned to Trent. Fred could see a suddenly puzzled look in his eyes. "Yes, that is strange ..." Then he laughed. "I suppose Gaddon is in the laboratory supervising the firing controls. Well, if he wants to miss the show, that's his fault. He knows the schedule."
