Sixth and final film with Montgomery and Russell. Kind of a Thin Man knockoff, but both were from MGM, so no-one's going to complain. Robert Montgomery is Joel, married to Garda (Rosalind Russell). Joel is hired on to figure out why books from a rich guy's collection are mysteriously appearing on the street, and no-one is reporting them missing. Keep an eye out for Ralph Morgan, as Nick Torrent, owner of the collection. You probably know Morgan's BROTHER, Frank, who was busy making Wizard of Oz, around the same time! Sound and picture are pretty good...looks like it has already been restored. You'll see the same recipe they used in Thin Man... clever but antagonistic banter between hubby and his feisty wife, and they slowly but steadily try to solve the mystery at hand. Reginald Owen is "Charlton", probably best known as the cult leader in Rosemary's Baby. Étienne Girardot is the nervous, little twitchy guy, "Oates", who seems to be mixed up in here, somehow. Girardot was already 82, and he died soon after this came out. some good chemistry between Monty and Russell, who had already worked together so many times. It's fun. shows on Turner Classics here and there.
