What happens
Clark Kent and Batman search for Robin, who has been taken by the Monkey Burglar's gang, and follow a clue about a state gymnastics medal. Inspector Henderson is under pressure to solve the case within a day. The pair track down former medal winners one by one, visiting the Ains and Edwards families and finding each boy ruled out. Their last lead is Billy Riggs of Metropolis. Meanwhile, a thin man named Fighter Jones and his partner talk in a tenement about their final job and a missing lucky medal belonging to Robin. The episode is part seven of The Adventures of Superman, first broadcast on February 20, 1947.

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.
