The lady in the lake.

In The Lady in the Lake, hardboiled crime fiction master Raymond Chandler brings us the story of a couple of missing wives—one a rich man's and one a poor man's—who have become the objects of Philip Marlowe's investigation. One of them may have gotten a Mexican divorce and married a gigolo and the other may be dead. Marlowe's not sure he cares about either one, but he's not paid to care.
