"I would rather have you not. It would probably kill me, and if by chance I survive, I'd be in a coma the rest of my life." Sherlock said. He gave the cabby an address. "Earl's Court Road."

About fifty minutes later (because traffic is hell in London), Sherlock stepped out of the car and looked around.

"You agreed to help me raid my apartment, stupid" she followed John out

Sherlock's eyes widened. "Oh yeah. This first. Would you rather have a raided flat, or an insane psychopath killing people for fun. Do choose wisely." he added sarcastically. John cowered behind Sherlock, not knowing whose side to take.

"If we get into a situation where we need a knife, I'm blaming it all on you, but go ahead and do what you want."

"A knife? What use would a knife be?" he hands you a gun. "Take it or leave it."

"nail sharpener." she smiled, knowing he wouldn't get it before taking the gun and pocketting it

"Whatever." Sherlock said, tossing you the gun. (which wasn't on safety by the way) "I'll do something about your flat later. I just need to find Moriarty."

She caught it and held it, nodding at John and waiting for Sherlock to lead the way

Sherlock headed towards an alley, where a man stood with a sniper rifle in his hands.
"Who goes there?!" he growled, a dot of light appeared on Sherlock's temple.
"Sherlock Holmes to see James Moriarty." Sherlock said, his face expressionless.
"He said he was expecting you." he stepped out of the way, letting Sherlock, John, and you pass.

She scented the air, walking slightly slower than the others, checking around.
