I'm not a big enough player to thrillers say that upsets Lemaître / revolutionize the genre .. but I must admit that in this plot extremely well put together and taut as a bow, the author masterfully blurs the Who is the victim, who is the executioner? and if the victim was the executioner ..? unless the executioner is the prey, who knows ..?
The style is bright and sharp, just to mention some pretty violent passages (do not have it read to your children under 16 years).
I just felt a little long in the journey of Alex: I'll withdraw a star, the smallest.
In summary: VERY GOOD thriller from start to finish.
