The Viking Funeral - Stephen J. Cannell

The Viking Funeral is a detective story about a police officer, Shane Scully, who's life is changed when he sees his best friend, who committed suicide two years ago, drive by him on the freeway. From there things start getting interesting. Scully takes more punishment in this book than John McClane did in any two Die Hard movies. He follows his dead friend into a case involving police corruption, drugs, money laundering, murder, and torture. It's quite a ride. Highly recommended.
