The protagonist of this story was Luc, a french ex-Interpol detective, that was transferred to Edinburgh. I really, really liked this guy, he is intelligent and kind to the people who are nice to him. I really liked his managerial skills, he knew how to deal with other colleagues, and I respect him for that. This story is told from multiple perspectives, but my most favourite ones were of the killer. I like reading their perspectives, and what kind of insanity drives them to do what they do. The book was narrated by Robin Laing, and he has done an incredible job! I would never read a book in accents, and his use of French and Scottish accents sounded amazing! Just like listening to a play, just close your eyes and you can actually “see” what is going on.
