A man is murdered at a seance which Charlie Chan's daughter Frances (Frances Chan) was attending. The police detective (Joseph Crehan) forces Chan (Sidney Toler) to investigate the crime or his daughter won't be getting released any time soon. Chan's chauffeur Birmingham (Mantan Moreland) was also in the house as a servant, and thinks there are some spooky goings on. In fact everything spooky is really a trick...
A problem for Chan is that multiple attendees at the seance had motives. However, he begins to unravel a clever plot involving false identities, hypnosis and fiendish weapons...
There is nothing wrong with this film at all, the crime is inventive and the solving of the puzzle very satisfying. Its nothing really you haven't seen before with Charlie Chan, though him being assisted by a daughter instead of one of his sons is interesting. An enjoyable film. Interestingly Frances Chan played one of Chan's daughters in a much earlier film (1933's Charlie Chan's Greatest Case) in the series too!
