Dana was walking quickly towards Moriarty's office. She was repeating her orders in her mind, and just before she entered his room she replaced her stressed look with a blank one. The only opposite site in being a serial killer was that she had become a very good actress.
She opened the door. She knew she didn't have to be invited. She entered the large room and headed straight to his desk, where he sat, smiling smugly.
"What is it, dear?"
"There was a message left for you."
"Show me." his face became interested.
She typed up quickly in his computer, and in seconds the camera in Sherlock's room was up.
"My suggestion is very clear – we want to leave this place, unharmed, without hurting anyone. The only way it'll happen is if you'll let us leave." Sherlock spoke directly to the camera, and Moriarty rolled his eyes, still smiling. Sherlock looked so pathetic to him. "And since I already know you, I know you wouldn't do it for nothing. I'm not going to offer you a certain sum of money, because I know you're not interested in it. I want to offer you what you wanted the most all along." Moriarty's eyes widened. Could it be? It the great detective finally telling him his secret? "Your freedom."
Moriarty laughed in contempt. Does he honestly think he is threatening him in any way?
"You'll let us go, and in return, I won't destroy you like you destroyed me. I know who you really are, James Scott. I know everything about you. I could return you the favour easily." As Sherlock's smile grew bigger, Moriarty's smile faded away. He was genuinely afraid. His web, his empire, was in danger now. He could either lose the game or lose it all.
"You're free to leave." he said coldly to her.
She turned around and walked away quickly, trying to keep her smile hiden.
"Wait."
She turned.
"Didn't you forget something?" he asked. He opened the drawer in his desk, ad pulled out a file.
"You didn't burn it." she said in relief.
He handed it over to her. She walked to him quickly, and as she took the file from his hands, she led herself smile. Her smile was grateful, and he smiled back to her. At the moment she didn't stop to think about the strange situation – why is Moriarty voluntarily giving her what she wanted? She was too happy to think about it. She felt like she got to Sherlock's room in seconds, and she opened the door with a large smile. Both men got up and smile back to her. They realized the plan worked. Sherlock glanced at her hand and saw what she was holding. He took it away from her gently. She tried to take it back from him, but he whispered: "Wait until we're home." So she led him take it.
They walked out together, and none of the guards in the entire building disturbed them.
