Thin Man [Blu-ray]

First and best of the famous whodunit series has the wisecracking, martini-sipping husband-and-wife sleuthing team of Nick and Nora Charles investigating the disappearance of an inventor who later is implicated in the murder of his secretary. The film, an adaptation of a Dashiell Hammett private-eye classic, was followed by five sequels. Incidentally, "The Thin Man" refers to the inventor, not Nick Charles.
