I discovered Franck Thilliez with the syndrome S & Gataca (which I liked bcp), then I read his other books, such as 2 previously mentioned, have really seduced me. So I waited with some impatience the new thriller & I confess that I have not been disappointed! This is a masterful closed-door which leads us into the depths of the human soul. Taking a book so that I no longer wanted to let go of the day & have eaten in a few hours with undisguised pleasure :) I can only strongly advise large thriller written by a great author !!!
