The Thin Man

New York City residents Nick and Nora Charles are vacationing in California where Nick previously lived. The former detective still knows a number of people in town, and when one of his acquaintances, Clyde Wynant, mysteriously disappears, he is reluctantly drawn into the case by his own wife and the man's daughter. The Charleses have been living off Nora's considerable wealth since they wed, so Nick doesn't need to return to sleuthing. But Nora finds it exciting, and soon Nick is tracking down Wynant (the Thin Man of the title) who proves to be a murder victim. This brings him into contact with all sorts of unsavory characters who eventually wind up at the Charles's Christmas party where the guilty party is unmasked.
