This isn't my first encounter with this author. In theory, I knew what to expect, but some moments sent shivers down my spine.

The book is substantial, but the action's brisk pace, the dialogues' lightness, and the gripping story make it a quick read. I recommend it to those with strong nerves. What intrigued me the most was the biological aspect of the story - numerous theories and speculations. I'm not sure how plausible what the author writes is, but he skillfully and logically builds tension around his characters.

I enjoyed the duality of the narrative - apart from the standard narrator, we also have the killer's stream of thoughts. I'm reading "The Leopard," and I feel that J. Nesbø employed a similar effect there.

The book has its poignant moments as well. One of the more exciting and favourite characters bids us farewell... unless the author finds a clever way for his spirit to remain with us. I've always liked the parts with his involvement and interactions with Harry.

The final rating is 4/5 for personal reasons I won't disclose here. I recommend giving this read a go, even though it's as bloody as its title! :-)
