At a Paris book exhibition, a head of state is shot in daylight and the hall is sealed in a storm of procedure, panic, and “official” certainty, yet the Belgian Detective and his loyal companion quickly sense a second story moving beneath the polite banners: a man who would not applaud, a weapon that arrives like a delivery, a badge that opens service doors, a bookseller’s stand with no books, and a briefcase of papers passed hand to hand as the crowd is pushed toward a simple explanation; inspired by historical crime of its era while remaining entirely fictional, The Bullet in the Bookstall is an original Golden Age–style mystery about propaganda, scapegoats, and the quiet machinery that tries to manage truth into a headline.
