516UpgT9p9L._SY346_Detective Harry Hole is assigned to the case of a young woman who has been found murdered in her flat with a tiny red diamond in the shape of a five-pointed star behind her eyelid. Having to work alongside his nemesis, Tom Waaler, does not appeal to Harry but as he is already on his last warning, he must overcome his hatred for his fellow detective and rouse himself from his alcoholic state when he realises that a serial killer is stalking Oslo.

The Devil’s Star¬†is the fifth in Jo Nesbo’s Harry Hole series and I can safely say it is my favourite so far. Drinking heavily after becoming estranged from his partner and still trying to come to terms with the circumstances behind his colleague’s death, Harry has been avoiding work like the plague. With the National holidays in full swing, however, and a skeleton staff in operation, his superiors have no option but to call him in to work on the serial killer case. Despite his shortcomings, Harry definitely leads a charmed life, as any other police officer would have been thrown out of the force a long time ago!

There were two main reasons why I liked this book so much, the first being the serial killer plot. I enjoyed reading how Harry worked out the pattern that the killings took as it showed that, although he is struggling with his demons, his investigative skills are second to none and the reason he is still able to operate as an officer. There were several clever moments in this plot, not least when the identity of the killer was revealed. There were also some moments that the squeamish would not enjoy!

The second thing I really enjoyed was the Tom  Waaler storyline which reaches a dramatic conclusion. This particular plot has kept me hooked for the past few books and I was pleased with how Jo Nesbo brought it to an end.

I have read that this series gets better as it progresses and I definitely agree! I can’t wait to read the next one!
