Mathieu Sapin provides us with the Chateau, a mocking journey down the corridors of the Elysee. The goal is not to commit a pro or anti Holland pamphlet, nor reveal adulterated scoops but rather to penetrate the secrets of this mysterious place, the epicenter of power in France and to draw up a panorama as faithful as possible. Small hands are busy behind the scenes to prepare for the summits, the bodyguards who train in the dojo, the flower that lines the daily tables, etc. all this is made with deep respect and curiosity of good quality. Then there and everywhere the ball of various advisors, waltzing at high speed, prematurely worn by the political machine, also from the cohort of journalists everywhere, and behind the scenes, making a permanent information, made frantic by acceleration of time and the development of the ephemeral, continuously info channels, twitter, etc. Overall a very good book, which shows and do not judge, always keeping an amused distance and a refreshing surprise.
