Quick-witted rare book seller couple Joel and Garda Sloane occasionally dabbles in the dangerous world of detectives. Absent-minded Mr. Oates tells them that cash-strapped Nicholas Torrent is looking to sell a rare scrap of a William Shakespeare manuscript. They track down Nicholas for Oates and they uncover a mystery of missing books.
A fast talking couple solving mysteries is almost a genre of its own with William Powell and Myrna Loy as the movies gained sound. This is a sequel to a movie from a year earlier although that one stars two different actors. The mystery genre owes a lot to Agatha Christie. In many ways, it's a copy of a copy, a sequel to a follower. I hate to say it but it reminds me a lot of all the Lifetime mystery solving people whether they're book sellers, gardeners, or bakers. The quick retorts have moments of almost humor. I don't mind the leads although I don't see how people can develop attachments to a constant rotation of actors for the same roles. I would rather have more of the rapid fire dialogue between the married couple than the slow moving mystery.
