"Hello?"

"John."

"Hey Sherlock, are you okay?"

"Turn around and walk back the way you came!"

"No, I'm coming in."

"Just do as I ask. Please."

"Where?"

"Stop there."

"Sherlock?"

"Look up, I'm on the rooftop."

"Oh God."

"I...I...I can't come down, so we'll just have to do it like this."

"What's going on?"

"An apology. It's all true."

"What?"

"Everything they said about me. I invented Moriarty."

"Why are you saying this? Sherlock!"

"I'm a fake. The newspaper were right all along. I want you to tell Lestrade, I want you to tell Mrs Hudson and Molly. In fact, tell anyone who will listen to you, that I created Moriarty for my own purpuses."

"Ok, shut up, Sherlock, shut up! The first time we met, the first time we met, you knew all about my sister, right?"

"Nobody could be that clever."

"You could."

"I researched you. Before we met I discovered everything that I could to impress you. It's a trick. Just a magic trick."

"No, alright, stop it now!"

"No stay exactly where you are! Don't move."

"Alright."

"Keep your eyes fixed on my. Please? Will you do this for me?"

"Do what?"

"This phone call, it's...um...my note. That's what people do, don't they? Leave a note..."

"Leave a not when?"

"Goodbye, John."

"No, don't!

SHERLOCK!"
