Phantom is the seventh book (published in English) in the Harry Hole crime series by Scandinavian author, Jo Nesbo and the first that I have read. It took me a little while to become involved in the story, primarily because of the many different voices used to tell the narrative, however once I had time to read a few chapters without interruption I found the book hard to put down.
Harry Hole has returned to Oslo from Asia when he learns that Rakel's son, Oleg, has been charged with murder. As Harry determines to discover the truth his investigations involve understanding the structure of the Oslo drug trade including its infiltration into the police force and city hall. Harry is a flawed and damaged character facing many demons from his past as well as the dangers he encounters from those following him throughout his investigations. The book is about addiction - drugs and alcohol - but it is also about making choices and doing things because, rightly or wrongly, they are the right things to do.
