Her majesty's location Nottingham, the diamond jubilee, State of Emergency declared in Burma, More requests from the Greek government. Heavy rains predicted. Bring Umbrella.

II: His forced confession had done its job. Mycroft Holmes had received the one thing that the government had always been loathe to give him. Time off. He used that time to make arrangements for Sherlock to leave the country. He had been involved in some delicate negotiations. It wasn't a good time to be distracted from his work, but then again, his little brother always had been a distraction.

This time, however, his interests and Mycroft's were aligned. Moriarty had been a thorn his side time and time again. A chaotic element in the shifts of power that kept the world running smoothly. Who would guess that James Moriarty would have become infatuated with his little brother? Who would have guessed that Sherlock Holmes would allow himself to die to the world, would allow the media to call him an idiot, just to destroy this criminal's network? It was surprising. But then, Sherlock had always been surprising ever since he was a child, back when his greatest ambition was to be a pirate. Although Mycroft would never admit it, Sherlock made his life bearable, because he always had a way of doing the unexpected.

IV: "I'll be going to Pakistan first, and then Tibet. How do I reach you?"
"You have my number."
"This money won't last for long."
"Don't worry about money. Moriarty stored his private bank account numbers on his phone. You can use his own ill gotten gains to bring down his organization. Poetic justice, is it not?"
"So those were bank account numbers stored in the databank? I thought that they were encrypted?"

" A simple substitution cypher, I believe. It shouldn't take long to decode. I will send it to you."
"Give me the numbers and I'll figure it out myself."
"No need. I told you that I'm working on it."

Sherlock nodded and covered his dark curls with his hat. He pulled up the collar of the cheap dockman's parka that he was wearing, and walked to the door. "You will watch over things while I'm away won't you?"
"I always watch over things. What things in particular concern you?"
"I'll want my coat back."
Mycroft laughed, "You always fill your mind with such useless trivia, my dear brother."
"And John. Will you keep an eye on John?"
"Two eyes, whenever I get the chance, and ..."

"And what?"

"A small thank you wouldn't go amiss."
"What for? If you hadn't let Moriarty's organization get out of hand, then I never would have had to leave London in the first place. It's time to go. Goodbye Mycroft."
"Good Luck, Sherlock."
