Tehran, 1934: a world-famous American heiress is found strangled in an elegant blue drawing-room after a private quarrel with the heir to the throne, and the city’s officials demand discretion before headlines can ignite an international scandal; as the Belgian Detective and his loyal companion move through garden walls, guarded corridors, and immaculate reception rooms, they follow missing love letters, a terrace door left ajar, a royal cuff link placed too conveniently, and a “perfect” piece of evidence that appears too late to be innocent, revealing a murder shaped not only by jealousy and pride but by the terrifying speed with which a state decides what truth is allowed to exist; inspired by historical crime and political atmospheres of its era while remaining entirely fictional, The Blue Drawing-Room is a tense Golden Age–style mystery about power, reputation, and the violence that hides behind protocol.
