I can not say anything more than has already been said above. This thriller is frankly very different from the (English or American) that one has the habit of reading. Very original, cruel, violent, bloody .... (definitely not for the faint hearted) but is caught in this story full of twists and very clever one who could discover the "strings" before the end. I loved also the writing style, short sentences, fluid, not at all childish as I read in the comments and I think that this style gives more to the story that is divided into three parts that which is also its originality. And what about the cop Camille most atypical !!!!!!!! I liked it a lot. Of course nothing to do with the beautiful American cops, tanned, muscled 1.90 m, it measures 1.45m and is struggling to put his feet on the ground when seated. But that does not prevent him to have a "brain" that works 100 per hour. As for ALEX we love, it is complaining, hate it but it can not leave us indifferent.
