I liked this inversion of roles and perspectives, the idea of making us follow the victim, make us tremble for her, with her despair ... to discover that the worst torturers, n ' is other than itself! Until the second turnaround, where former victim that proved to be the real monster, reveals, through the investigation of the cop before becoming his victims, his targets were the culprits well cruelest she never would be and that their rather sadistic punishments were even deserved. Lemaitre make us feel compassion, the incomprehension and anger against this anti-heroine, we end up actually know only at the end, and we gladly forgive ... if not 'approve' '. Eventful, complex, shielded false pretenses, this novel is good without leaving the aftertaste never seen that one would have liked to find.
