Sherlock Holmes - The Cartographer’s Cathedral

Former Scotland Yard detective Emre Karasu is a man haunted by the past. On the fifth anniversary of his partner’s death, a mysterious package arrives at his London flat-a pair of Ray-Ban Meta smart glasses. When he puts them on, a calm voice introduces itself: 'Hello, Emre. I am HOLMES. I have been waiting for you.' The glasses reveal a hidden message on the wall across the street, and moments later, Emre watches his long-dead mentor gunned down before his eyes. So begins a labyrinthine game orchestrated by a shadowy figure known only as the Cartographer.Armed with the AI’s deductive genius and a medical empathy module called DR. WATSON, Emre plunges into a world of ancient secret societies, encrypted murders, and impossible puzzles.

But the most terrifying revelation is yet to come: the Cartographer isn’t just a killer-he’s a split personality born from a chip implanted in Emre’s own brain. The murders, the ciphers, the breadcrumb trail of horrors-all of it has been orchestrated by a part of himself he never knew existed.Now Emre must race against time to stop a ritual that could merge his consciousness with the AI and unleash a new form of life upon the world.
