Complete story — includes the ending
Moriarty reveals that she faked her murder to distract Sherlock from interfering with her plans, though she did not anticipate his drug overdose. She asks him to let her win and then he can have the United States all to himself. Sherlock uncovers her plan to have the father ( Arnold Vosloo ) of a woman she kidnapped, in addition to smuggling in two lemurs, murder a family associated with the Macedonian naming dispute to make $1 billion trading in currency. He fails to stop the murders after the family's security officer betrays them, and vents his rage against Joan and Gregson. Sherlock purchases drugs and injects himself in the bathroom of the brownstone, where Bell finds him. Moriarty visits him in the hospital, confessing to her part in the murder. She invites him to leave the country with her, where she will help him overcome his addiction. Sherlock reveals that Joan analyzed Moriarty's behavior and concluded that she was in love with Sherlock and thus would return to him; they relied on Moriarty's agents to witness his wild behavior and let her think that she won. The overdose was faked and Moriarty is arrested, Sherlock having recorded their conversation.
