The Man Who Smiled by Henning Mankell

This book has all the parts for a great murder mystery: a man with no enemies who turns up dead, a cop who's good at his job but bad at his life, and lots of great detective work. These books are more interested in the psyche of Kurt Wallander and digging up how the police solve the cases than in tricking the reader (who knows from almost the first page who dies and why). A really engaging book.
