London, winter: a confidential War Office memorandum vanishes from a locked dispatch case and Captain Paul Lévy becomes the “convenient” culprit—punished by whispers, closed doors, and polite disgrace—until an anonymous note points to General Vallon’s dinner and claims the wrong man has paid; the Belgian Detective and his loyal companion follow a trail of keys, access, and carefully managed reputations through official corridors and private loyalties, where the real theft is not only of paper but of a man’s name; inspired by the atmosphere of interwar secrecy and prejudice while remaining entirely fictional, The Stolen Memorandum is an original Golden Age–style mystery about authority, scapegoats, and the quiet violence of respectability.
