Dancers in Mourning (Albert Campion #9) 

An old friend of Albert Campion, "Uncle" William Faraday, has written a successful book that has been turned into a hit musical comedy. Jimmy Sutane, an established actor and dancer, is the star of the musical. But recently someone has it in for Sutane and has started playing harmless practical jokes that have caused the highly emotional Jimmy much trauma. Jimmy asks Campion to look into who the prankster may be. So Campion takes a trip to the Sutane household, where he unexpectedly finds more than he bargained for.
