Dressed to Kill

In this entry in the Michael Shayne detective series, the smart-alec sleuth is at the altar with his bride when shots ring out from a nearby theater. He immediately runs to investigate. He soon finds a series of murders with one thing in common. They are all related to a single stage production. Each victim is discovered wearing a costume from the drama. Shayne soon discovers that the killer is a jilted porter whose actress-lover dumped him. Unfortunately for the enthusiastic gumshoe, his fiancee, disgusted by his love of solving mysteries, dumps him.
