What happens
Dr. Singer, a physicist working on a top secret thermonuclear weapon, becomes the focus of a counterintelligence hunt after a dying man reveals that the project's progress is reaching the Soviets. Special Agent Whiteside of the FBI and General Busher of the Atomic Energy Commission are told that someone among the six men on the project is passing information out of the country, and they begin watching the scientists closely. As suspicion moves from one colleague to another, agents track each man's movements and arrange medical examinations. Singer is pressed to help find the traitor while his own loyalty is questioned. The episode is part of the radio series Suspense, and it is presented as a CBS broadcast from June 28, 1951, with Joseph Kearns in the title role.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
