Filmed on the very cheap, Mystic Circle Murder (aka Religious Racketeers) is distinguished by the presence of Mme. Harry Houdini, in a rare movie appearance. The widow of the famed magician introduces the film by warning the viewer to steer clear of phony psychics who promise to communicate with the dear departed. The story proper then gets under way, with fake fakir La Gagge (Robert Fiske) fleecing wealthy widows Ada Barnard (Betty Compson) and Martha Morgan (Helene Le Berthan). Throughout the film, the many gimmicks used to sucker the gullible into believing they've reached the Great Beyond are exposed and explained. Outside of its novelty value, Mystic Circle Murder has very little to offer.
