Mr. Moto (Peter Lorre) investigates when a boxer is killed in the ring … but from poison rather than a blow. Originally planned as a Charlie Chan film and rewritten for the Mr. Moto series, but still with Charlie’s Number One Son Lee Chan (Keye Luke) on hand to help with the investigation, the mystery is a bit more mundane than usual. Still, Lorre is appealing as always in the role, and there are some good sequences, including the setup for the final trapping of the killer.

  Mildly recommended. Otto judiciously thinks this movie is OK, but not great.

Movie 216 for 2021.
