I recently finished "Nemesis" by Jo Nesbo, a Norwegian aurthor. If you are looking for a mystery with great character development, a very intriguing and intricate plot or plots, then this book should appeal to you. It is part of a series of mysteries featuring an alcoholic detective, Harry Hole (sounds like a name I would have found a place for in one of my mysteries, but since Jo has already used him, I guess I can't). Check it out.
