"Do not be overcome by evil, but overcome evil with good." -- Romans 12:21 (NKJV)
Fans of the Harry Hole series need to be prepared for a book that may upset them more than it pleases them. Harry Hole is a wreck here, drawn back into police work merely so that he can be close to his dying father. It's a brilliant portrayal . . . but it's also shocking and disturbing.
The task is to stop a serial killer, a particularly gruesome one. Jo Nesbo writes about the evildoing in a way that will make a big impact on you. If you like your murders neat and clean, this isn't the book for you.
Although the writing is powerful and emotionally moving, the facts seem a little off. It doesn't quite ring true. You almost have to imagine that you, too, are being affected by illegal substances to fully appreciate the story. Normally, the reader is allowed to remain in an unaltered state while reading such a story. It didn't quite work to try to bring us into Harry's world to the extent that Jo Nesbo tries to do here.
Should you read the book? Well, if you are at all squeamish, consider taking a pass. If you love dark, psychologically dense fiction, gird your stomach and read on.
