This book is the result of two years of investigation into the networks and methods of one of the most powerful men in france. An investigative book on the borders of business, politics and the freedom to inform. The authors are seasoned investigative journalists, those who don't let themselves be intimidated. Courage was needed to complete this investigation of vincent bollor�, a man who likes to own the media but not to be investigated. One of the authors was thus surprised one day to receive a summons asking him for 750,000 euros in damages for having just sought to interview the senior executives surrounding the businessman! 750,000 euros for just wanting to exercise the profession of informing, which supposes giving the floor to the people we are talking about, it is expensive to pay. Does mr. B have things to hide? Far from dissuading the authors, this unprecedented episode of intimidation of the press even before publication confirmed them in the idea that their investigation was for public health. Methodical construction of an empire with multiple ramifications. They dissect the methods and the personality, as admired as it is feared, of one of the most powerful men in france, who knew, in twenty years, to conquer political circles, spheres industrial and financial, in france and in africa. They tell the story of this universe, where politics, finance and media intersect and where moods are the prerogative of the weak and bluffing the weapon of the powerful. They wonder about the fragility of freedom information in a media world increasingly concentrated in the hands of a few financial empires.
