Murder on a Honeymoon is an American 1935 mystery film starring Edna May Oliver and James Gleason. This was the third and last time Oliver portrayed astute schoolteacher Hildegarde Withers; the two previous films were The Penguin Pool Murder (1932) and Murder on the Blackboard (1934). The film was directed by Lloyd Corrigan from a screenplay by Seton I. Miller and Robert Benchley based on the 1933 novel The Puzzle of the Pepper Tree by Stuart Palmer. Palmer's novel, however, did not include Inspector Piper, and has Withers doing the investigating on her own.

Plot

On a short flight to Catalina Island off the California coast, a passenger named Roswell T. Forrest (Brooks Benedict) gets sick. Hildegarde Withers (Edna May Oliver) and the others aboard are startled when he is found dead upon landing. It appears to be murder to Miss Withers, but she has a tough time convincing local Police Chief Britt (Spencer Charters) and coroner Dr. O'Rourke (Arthur Hoyt).
