Il signore e la signora Sherlock Holmes

A man is shot in his car and a young couple is entangled with the murder. Next, the dead body is found in his library at home. Inspector Oscar Piper (James Gleason) investigates the apparent murder. He calls to cancel a golf outing with Hildegarde Withers (ZaSu Pitts). She's intrigue with the case and invites herself into the investigation.

The start is a bit messy but I like the young couple's dilemma. This is a new Hildegarde. She has a few fun scenes but it's generally a downgrade. I do like the handcuff scene. The mystery would work better if the young couple is forced to go on the run with Hildegarde by their side. They could solve the case together. Oscar would be in pursuit and join them later in the story. I just don't like the second half that much. The movie degenerates. The series is also degenerating into a secondary B-movie franchise. The original series would have one more movie before fading away.
