Synopsis by Hal Erickson
Le Mystere de la Chambre Jaune (Mystery of the Yellow Room) is based on a novel by Gaston Leroux, of Phantom of the Opera fame. Hugette Ex-Duffos plays a scientist's daughter, who is targeted for a murder by an unknown assailant. When the police prove unable to protect the heroine, wisecracking reporter Roland Toutain assumes the responsibility. Toutain not only saves the girl from a second homicidal assault but also exposes the killer's identity. Critics complained that the film was too faithful to the original Leroux novel, dwelling too long on exposition and extraneous characters.
