Hollywood Stadium Mystery is a 1938 American film directed by David Howard.

A rivalry develops between a district attorney named Devons, who finds murder mysteries amusing but amateurish, and Pauline Ward, a crime novelist.

They play tricks on one another, attempting to prove their point over how to solve a crime.

One night before a prizefight, when the lights are momentarily dimmed, a boxer is suddenly killed in the ring.

The police detain every spectator from ringside, considering them all as suspects, including Edna Mayberry, a woman who had an involvement with the dead fighter.
