Moriarty's conspiracy: A series of events make people around him doubt Shylock, including agents and the media. Don't leave Sherlock. The public thinks he is a liar. He directed those cases himself, solved them himself, and pursued fame and so on. Said that he hired an actor to fabricate moriarty, and he was speculating with Mo Dou. -in general, it is to deny Xia's talent for solving crimes! But we all know this is not true.
Except for several people in the play: Watson and Molly, the sheriff still believes in Shylock.
But in the end, don't threaten Xia to commit suicide to confirm those rumors, or you will kill Watson, the landlord and the detective. He jumped up to save their grace ~
