Adventure in Manhattan on AllMovie

Crime reporter George Melville (Joel McCrea) arrogantly repeated accurate predictions about jewel robberies. He befriends Claire (Jean Arthur), who involves him in a mysterious adventure. Later, George meets producer Blackton Gregory (Reginald Owen), who reveals Claire is an actress hired by other reporters who wanted to show George up. She's starring in a play Gregory is producing, but only as a cover for a tunnel he's having henchmen dig to an art gallery. Gregory is really Belaire, a master thief who everyone but George thinks is dead, so when Claire, now falling in love with George, innocently gives Belaire key information, he uses it against George. To Claire's dismay, this leads to George being fired and, apparently, going nuts.
