She Gets Her Man on AllMovie

Joan Davis, the daughter of a famed woman detective, has inherited none of her mother's deductive prowess. Nonetheless, Joan teams with patrolman Leon Errol to solve a series of blowgun murders. The two erstwhile Sherlocks track down the alleged murder weapon to a theatre, where it is being used as a prop in a play. After disrupting the performance, Davis determines that the murders weren't committed by blowgun, and that the culprit is a mild-mannered gentleman to whom murder is a "hobby." The title She Gets Her Man clues us in on the finale, and also refers to the shaky but affectionate relationship between Joan Davis and Leon Errol.
