A brutal drug. A shattered memory. A city losing its mind.

When a new synthetic drug called Golden Klok begins spreading through London, its effects are as terrifying as they are mysterious—hallucinations, memory loss, and eventually, death. In this gripping tale of crime and conspiracy, Sherlock Holmes finds himself pulled into a case unlike any other.

What begins as a personal tragedy soon unravels into a layered mystery, full of suspense and psychological tension. As Holmes investigates, he uncovers a chilling network of fake pharmaceuticals, experimental mind control, and a shadowy figure known only as the Watchmaker.

With time slipping away and his own mind beginning to fracture, Holmes must race through the dark underbelly of London's infrastructure to stop a plan that could alter the very nature of human memory.

A relentless blend of mystery, thrill, and classic detective fiction—this is Sherlock Holmes at the edge of reason, facing a threat that may be beyond even his understanding.
