Harry Hole, along with his new investigating assistant Katrina, are looking into a string of murders where women have been mutilated and murdered across Norway and a snowman is the calling card.
Highlights:
-It's discovered that the children of two of the murdered women have seen the same doctor, but that doctor refuses to reveal the reason. Then the doctor himself "commits suicide" - actually murdered and the police have egg on their face after declaring him the Snowman.
-A journalist who was in contact with the doctor had affairs with a number of the murdered women and, although he wanted nothing to do with the children, took them to a specialist because he had a hereditary illness he worried his children would inherit.
-A policeman who was on the track of the Snowman years earlier is found dead and mutilated himself in the small town where he lived.
-Turns out Katrina is that policeman's daughter and inserted herself into the police force and the investigation in order to solve her father's murder.
-The murderer has a close connection to Harry and even made himself a part of Harry's life in order to control the murders and their investigation.

Reaction:
LOVED! Deep, long yarn that can't fail to draw you in. I loved Harry, the range of characters and the depth of the murder case. I can't wait to read more in this series.
