In the shadowy streets of Victorian London, Sherlock Holmes faces his greatest challenge yet. As the detective's brilliant career reaches its zenith, a sinister presence emerges from the criminal underworld—Professor James Moriarty, the Napoleon of Crime.

With the stakes higher than ever before, Holmes and Watson embark on a perilous journey across Europe, leading to a fateful confrontation at the edge of the Reichenbach Falls.

Arthur Conan Doyle's "The Final Problem" pits the world's foremost detective against his intellectual equal in a battle of wits that will test the limits of reason, loyalty, and sacrifice. This is Holmes as you've never heard him before—vulnerable, hunted, and all too human.
