Sherlock: I need your help.
Hermione: With what?
Sherlock: I'll tell you about it in person.
…
"So you've managed to track her down, but so has this terrorist cell, and they're going to execute her in Karachi if their demands aren't met in seventy-two hours?"
"Sixty-nine and a half, now."
"So what do you want to do?"
"Fake her death, obviously. Get her out of the game."
"You know you won't be able to see her for years. At least until Moriarty is resolved."
"I can't let them just kill her, Hermione. It would be like killing the last Amur Leopard."
Sherlock waited for several minutes while Hermione thought. They walked around the frozen park in silence.
"Are you going to help me or not?"
"Of course I am. How good a fake death are we talking, here?"
"Good enough to fool Mycroft. He's going to want absolute proof that she's dead."
"So, video cameras, and a body that can stand up to forensic analysis?" Hermione tapped one finger against her lips.
"If you can swing it."
"Oh, I can swing it. I told you I'd spent a lot of time considering how I ought to have disappeared my parents, didn't I?"
"I do recall something of the sort."
"We're going to need a sample of her hair or blood, an animal with approximately the same body mass as the target, and an invisibility cloak."
"Invisibility cloak?"
"Yes," Hermione said firmly. "If you get the first two, I'll talk to Harry about the last. Meet you at my place in three hours."
