8. A classic detective novel. It must include a detective, amateur or professional. This list of books from the Golden Age of Detective Fiction is a great starting point if you're looking for ideas.
Nick Charles was a detective in New York until he married Nora, at which time he moved to California to manage the various businesses left to Nora by her father. They are back in New York on vacation when the secretary (Julia Wolf) of a former client of Nick's (Clyde Wynant) is murdered. Everyone assumes that Nick is working the case. He isn't too sure he wants the case, but Nora is fascinated with the idea. Nick and Nora spend most of their time drinking. I kind of liked the book, but not as much as the Lord Peter Wimsey series by Dorothy L. Sayers; I think the characters in Sayers's books are much more likable and engaging. I rate The Thin Man 3 out of 5.
