What happens
Superman, disguised as reporter Clark Kent, investigates the mystery surrounding the dragon's teeth, ten pieces of Chinese jade said to hold the secret of everlasting life. Lois Lane and Jimmy Olsen of the Daily Planet visit Chinatown scholar Dr. Chi Wan, whose tea has just poisoned their editor, Perry White. Superman arrives in time to stop them from drinking it and questions Dr. Wan, who admits to owning nine of the dragon's teeth and names Walter Huffman as the owner of the tenth. Later, Dr. Wan is found beaten to death, and Lois begins to suspect Superman. The story is part three of The Dragon's Teeth serial from the Adventures of Superman radio series, first aired on February 14, 1941.

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.
