Warner Oland works on behalf of French Archaeological Society concerning Egyptian antiquities being sold to private collectors and rival museums. Before the case is solved, Chan will uncover and solve a murder and avoid being done in. Mystery is pretty straight forward with fewer misleading clues than most of this series. "Theory like mist on eyeglasses -- obscures facts." Chan still (as usual) does not reveal all until the end although this time with the paucity of suspects it is more likely that you can guess the guilty party. Story relies more on travelog-type shots, similarity to real-life and contemporary film mysteries about mummies and tombs, and basic lectures on how X-rays work and archaeology to keep interest. It works. Pat Paterson (Charles Boyer's real life wife) does a credible job as the damsel in distress and under the influence of cannabis. Stepin Fetchit's role as a bug-eyed dim-witted servant will upset modern viewers and probably served as comic relief to contemporary audiences. Although an unrecognizable Rita Cansino (Rita Hayworth's real last name) is given a credit at the beginning of the film, she hardly has any lines. Not as good as Charlie Chan in London or Paris, but one that dedicated fans will not want to miss. Recommended.
