What happens
Clark Kent learns that gangster George Latimer, whom Superman once helped send to prison, may possess the last piece of Kryptonite, which strips Superman of his powers. Kent and his friend Bruce Wayne plan to break into Latimer's house to find it. Kent is arrested by police and later learns that Latimer has publicly challenged Superman to appear on stage with him to answer charges of blackmail and framing. Kent is left troubled by the threat. This is part two of the 1947 episode in The Adventures of Superman radio series, broadcast on May 15, 1947. The cast is not named in the transcript.

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.
