Summoned to a Highland estate, Dr. Watson finds himself among tartan, whisky, and whispered tales of a blood-red stag said to grant immortality. But the moors hold more than legend. Outlaws stalk the glens, danger waits in the shadows, and every crack of rifle-fire may signal death. Alone in the wild north, Watson must rely on courage, instinct, and the hard lessons of war. For in these hills, man and myth walk side by side—and mercy may prove as powerful as the gun. A thrilling Sherlock Holmes adventure, rich with Highland mystery, danger, and unforgettable suspense.
