CHAPTER 3
Meanwhile, Irene Adler heads to a teahouse, where she meets with an unseen man seated at the next table.
Irene is obviously frightened as she explains that she delivered the package, but lost the letter.
She glances suspiciously at her teapot, and asks the server for a fresh cup. The server brings the tea, and she drinks.
Professor Moriarty (Jared Harris) reveals himself, expressing his displeasure in Irene's performance.
He says that she let her feelings for Holmes get in the way of her judgment, and he informs her that he will no longer require her services. Moriarty mocks Irene for setting their meeting at her favorite teahouse. She obviously believed this would keep her safe. Moriarty taps his spoon against his cup, and every single person in the noisy, bustling teahouse suddenly falls silent, gets to their feet, and exits.
They have obviously been hired by Moriarty to pose as customers.
Irene likewise gets to her feet and tries to run away. Moriarty calmly sips his tea as china smashes and a body falls to the ground.
Cut to Holmes, who is waiting for Irene to meet him for dinner. He glances at her watch - she is 10 minutes late.
He knows something is wrong, but he tucks his napkin into the neck of his shirt and begins to eat.
