The Threat Of Many

I don't own BBC'S Sherlock. A sort of sequel to my first Sherlock fanfic Revenge, But if you haven't read it, it should still make some sense. Moriarty has finally been jailed.. The end of him? Wrong. Nothing has made his underground followers so determined to help him. They want him out. Now. A gang poses a threat to London. Sherlock and John really do have their hands full..
