The secret of Chimneys, a novel written by Agatha Christie and published in 1925, tells the story of Anthony Cade, a tour guide with an adventurous past, who accepts a seemingly innocuous assignment: to deliver a scandalous manuscript and some compromising letters to a London publisher. But behind that simple commission lies a web of deceit, blackmail, and international conspiracies that will draw him into the ancient and majestic Chimneys estate, home of the Caterham family. Amid dark corridors, state secrets, and the threat of a scandal capable of triggering a diplomatic crisis in a small Balkan kingdom, the situation comes to a head when a guest is found murdered in the library of the estate. With a corpse, missing royal jewels, a mysterious criminal known as “King Vittorio,” and a Scotland Yard detective on the trail of the truth, Chimneys becomes the scene of an intrigue where no one is what they seem. With her unmistakable talent for plot twists, Agatha Christie delivers a brilliant and electrifying thriller—an irresistible blend of adventure, romance, and classic mystery—where every clue hides a double meaning and every character harbors a secret ready to explode.
