The game, as always, is afoot. In this collection of cases, Sherlock Holmes, the most formidable mind in all of London, turns his razor-sharp attention to some of his most baffling investigations yet. From the curious incident of a racehorse gone missing to the dark secrets of a dying detective's family, Watson faithfully records it all, one astonishing deduction at a time. But lurking behind every case, pulling strings from the shadows, is Professor Moriarty, Holmes's most dangerous adversary yet. The game between them has only one ending. And not even Watson sees it coming. Doyle at his most thrilling. Holmes at his most brilliant. And an ending that shook the world.

Twelve cases. Twelve times the impossible becomes elementary. Victorian London is a city of shadows, secrets, and crimes that leave Scotland Yard completely baffled. But they have a secret weapon — Sherlock Holmes, the most singular mind in all of England, and his loyal chronicler, Dr Watson, who records every deduction, every disguise, and every moment of breathtaking brilliance. From twisted murders to vanishing acts that defy explanation, Holmes unravels them all with the calm precision of a man who finds the world, quite frankly, too easy.
