The detective pursues a gang of armed thieves

The detective pursues a gang of armed thieves, seemingly intent on retrieving a missing diamond. An emerging witness insists on being referred to as Sherlock Holmes, claiming Professor Moriarty is behind the robbery. Even introducing author Arthur Conan Doyle to the scene fails to convince him otherwise. Yet despite his delusional state, it seems he holds the key to locating the jewel. Geraint Wyn Davies guest stars, with Yannick Bisson
