What happens
The Shadow, a wealthy crime fighter known to his aide Margot Lane, investigates a series of mysterious sinkings of ships on the high seas that have left many dead. Their inquiry leads to Joseph Hart, a disgraced naval designer, who reveals a secret about a private submarine and its owner, Vincent. The story follows the Shadow's attempts to locate the submarine and stop the attacks on merchant and passenger vessels across the Atlantic. This episode of The Mercury Theatre on the Air first aired on June 12, 1938, and the story is told through dramatic radio performance.

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.
