After "The exile of angels," Gilles Legardinier returns with a novel whose subject is sufficient to itself icing we bloods: Alzheimer's disease. And he treats as a thriller, while taking care to respect the patients with this disease. Here, no trash just to trash, on the contrary, his writing is subtle and compassion for the sick transpires each time a case is mentioned. The characters are profoundly human and a wide range of feelings is transmitted to us through them. Sure, the plot is not very original (a plot to capture a fundamental discovery), but the fact that Alzheimer's is at the heart of the problem, for me completely changed the situation. A novel that brings out everything that there may be good, but also bad in humans and also a beautiful reflection on the future of our planet and how the men used for their own purposes , often forgetting the basics. A novel that will reach many readers in the subject and the sensitivity that emerges from the writing of Gilles Legardinier. A big favorite.
