Two different cases — a missing person inquiry and an unsolved murder — intertwine in this later Sidney Toler Charlie Chan film. The detective, assisted by son Jimmy (Victor Sen Yung, making a welcome return to the series) and chauffeur Birmingham Brown (Mantan Moreland, entertaining as ever), cheats death as he pursues his investigation. Part of the solution is fairly easy to spot, but there are some pleasing unexpected twists as well. Mildly recommended.
