The Last Good Kiss by James Crumley
Drunken cowboy plays detective, gets mixed up with a drunken writer and his family. Seems a couple of them made some money writing books, so they can afford this nonsense of hiring a private detective for days on end. There are some good bits to it, and some action, but there is a lot of drinking and a lot of stupidity, and the way it ends doesn't really make any sense at all, except it sort of does, given all the other crazy s**t that's been happening. Good enough.
