Trent nodded. "I'd say that it sounded like the beginning of a very interesting theory." "And you would be right," Gaddon replied, warming to his subject. "It is my contention that the cosmic rays will prove to be the fountain of youth that men have sought through the ages. That they will react on the glands of a living creature and produce immortality. "Now take your choice. Whose theory would you rather believe? Mathieson's idiotic claims of a death ray, or mine as a source of the utmost benefit to science?" Trent took a moment before replying. When he did so, he spoke with tact, and also with the feeling that his trip to Fenwick's office had proven very valuable. For there was a story here. A big story. "I'd say, doctor, that I'd like to believe your theory was correct. But isn't it a little premature to be so definite about it?" Gaddon snorted. "No more premature than Mathieson's. And I'll tell you something else, Trent. You may not realize it, but you're about to take part in what may be the biggest story of the century. And when it breaks, you'll remember our conversation here. I intend to prove that your American scientists are wrong." Trent noticed the personal emphasis that Gaddon put in his last statement, but he was drawn away from the conversation as he turned the coupe into the guarded entrance to the proving grounds. There was a moment of credential flashing to the guards, and a respectful salute to the scientist in the car beside Trent. Then Trent moved his coupe through the entrance and up the cement roadway to the Administration building. As Gaddon got out of the car he turned to Trent. "I'll leave you here. The members of the Press will be conducted to the launching site at dusk. I'll see you then. In the meantime, don't forget that you've given your word not to release any of the information I've given you." Trent nodded and watched him walk away. He followed the Englishman with his eyes, a frown crossing his face. There was something too cocksure about the man. His ridicule of American scientists could be ignored, but the way he spoke about his theory, as if it had already been a proven fact against the ideas of Mathieson.... A faint chill ran up Fred Trent's back. He couldn't explain it. But it was there. An ominous note of foreboding. He shrugged it off and left his car to walk toward the Administration building. * * * * * The remaining hours of the afternoon dragged by in a monotony of idle speculation. Trent listened to the gathered newspapermen discussing the coming experiment at dusk, accompanied them as Dr. Mathieson, the head of the project, conducted them on a tour of the project, to the launching site, and then back to the central building.
