Jo Nesbo writes another excellent thriller

Harry Hole returns to Oslo to attempt to clear the name of the boy, Oleg, who he helped raise. Oleg is accused of murder and is being held by the police.

To follow the trail of the murderer, Harry becomes involved in the Oslo drug trade. He has learned that the murdered boy, Gusto, was known as a drug dealer.

There is also a side story with an alternative point of view as the reader experiences Gusto's life and how he came to his death.

In the story, Harry deals with a number of memorable characters and it is difficult for the reader to determine who is honest and who is not. Even members of the police are suspects.

Since the police could be involved, it is difficult for Harry to find someone to trust and to help him. The reader has to feel for his plight and wonder how he could succeed.

The author has many surprises and where some readers are able to guess at who the killer might be, this novel is unique that it is impossible to tell who is Gusto's murderer.

The conclusion is powerful and the reader is left with the uncertainty of Harry Hole's fate.
