This serial, written by Francis Durbridge, was first broadcast by BBC Radio in 1959.
It stars Peter Coke as Paul Temple and Marjorie Westbury as Steve.
The story involves Dr Conrad’s daughter Betty, who has disappeared from her finishing school in Bavaria. Paul is invited by the police to go over there to help trace the missing girl. Initially, though, even he is baffled, since the only clue to the mystery is an unusual cocktail stick found in her bedroom. Can Paul work it out?
