The Phantom Broadcast (1933)
MysteryCrime
Director: Phil Rosen
A handsome radio singer has it all--fame, money, adoring fans--but what no one knows is that his accompanist, a hunchbacked piano player, is actually the voice behind the arrogant, abusive "singer"'s fame. The two men fall for the same girl, and when the singer turns up dead, suspicion falls upon his assistant and the girl.
