One of the best stories the Saturday Evening Post ever ran!...better still on the screen!
In this comedy/mystery a milquetoast ad man finds his good ideas constantly copped by ambitious coworkers. His boss doesn't even seem to see him. The ad man's wife pushes her husband into confronting his boss during a party. Unfortunately, the timid fellow finds himself accused of murder after a corpse is found in the trunk of his car. He is quickly incarcerated for the crime. Meanwhile his wife begins investigating in an attempt to prove his innocence.
