The Mystery of Mr. Wong is a thrilling mystery made at the height of Hollywood's fascination with Asian sleuths. In the second of what would be a six film series from Monogram, the methodical Mr. Wong (Boris Karloff) investigates the murder of an antiques collector. Along the way he deals with curses, smugglers, and an ever-evolving cast of suspects. Featuring a cast that includes Grant Withers and Lotus Long, the film was directed by William Nigh, the creative force behind such Monogram favorites as The Ape and Black Dragons!
