'Moriarty is the Napoleon of crime, Watson. He is the organiser of half that is evil and nearly all that is undetected in this great city.' ~Sherlock Holmes, The Final Problem Shipped off to an expensive resort in Switzerland, Sherlock, John, Millie and Emily begin investigating a series of disappearances. It's all going well; Sherlock's showing off, and John gets a holiday- when suddenly, the re-appearance of an old friend threatens to undo it all. In a spiral of misfortune, the foursome are exposed to the true extent of Moriarty's control: Emily finds herself trapped in a world of power, sex and Irish whispers, Millie is pushed over the edge, and John's loyalty is put to the ultimate test. And with Moran back for revenge, corruption is everything: no-one will be spared. The question is, just how far is Sherlock willing to go to win the game?
