An espionage agent investigates the theft of important secrets from a noted official’s home. Who among his household has been stealing the papers? Could it even be the official himself? The whodunit element is strong in this film, which predates and is distinct from the 1960s French movie series, but the pace is a bit on the slow side.

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

Movie 99 for 2021.
