The game has turned deadly, and the hunter has become the hunted. After a masterful gambit, Sherlock Holmes finds himself stripped of his reputation and his freedom, locked away in a military prison, accused of murder, and officially declared insane. His enemies have played their hand perfectly, removing the world's greatest detective from the board.

Left alone in a city that believes his friend is a disgraced madman, Dr. John Watson must step out of the shadows. His only lead is a 20-year-old mystery-the name of a long-dead man, Faulkner, whispered by a captured queen. Armed with little more than his loyalty and a desperate hope, Watson travels to the grim streets of Edinburgh to unravel a secret history of betrayal that connects a rising political star, the late Professor Moriarty, and Holmes's own enigmatic brother, Mycroft.

But as Watson digs deeper, he discovers that this is not just about clearing his friend's name. It is a battle for the soul of the British Empire, fought in a world of whispers, lies, and shifting allegiances. To find the truth, he must answer the ultimate question: in a game orchestrated by the world's greatest minds, where order is more important than morality, who can you truly trust?
