The Mystery of Mr- Wong

Detective James Lee Wong (Boris Karloff) must find the "Eye of the Daughter of the Moon," a priceless but cursed sapphire stolen in China and smuggled to America. His search takes him into the heart of Chinatown and to the dreaded "House of Hate" to find the deadly gem before it can kill again. The popularity of Asian detectives such as Charlie Chan and Mr. Moto prompted Monogram Pictures to purchase the rights to Hugh Wiley's successful James Lee Wong character. Boris Karloff appeared in five Mr. Wong mysteries while on hiatus from horror films.
