Mycroft Holmes: Good evening, Mrs Watson. I'm the other Holmes.
Mary Watson: You mean there's *two* of you? Marvelous!
Dr. John Watson: How did you know I would find you?
Sherlock Holmes: You didn't find me, you collapsed a building on me.
Sherlock Holmes: Uh, hmm... Right. Where are the wagons?
Madam Simza Heron: The wagon is too slow. Can't you ride?
Dr. John Watson: It's not that he can't ride... How is it you put it, Holmes?
Sherlock Holmes: They're dangerous at both ends and... Crafty in the middle. Why would I want anything with a mind of its own bobbing about between my legs?
Dr. John Watson: Oh, how I've missed you, Holmes.
Sherlock Holmes: Have you? Why? I've barely noticed your absence.
Dr. John Watson: What are we doing down here?
Sherlock Holmes: *We* are waiting. *I* am smoking.
Sherlock Holmes: Get that out of my face.
Dr. John Watson: It's not in your face; it's in my hand.
Sherlock Holmes: Get what's in your hand out of my face!
Dr. John Watson: I'm on my honeymoon!
Professor Moriaty: Are you sure you want to play this game?
Sherlock Holmes: I'm afraid you'd lose.
Chosen answer: That's the key code for his fortune concealed in his library. The one Mrs Watson uses to relay to Inspector Lestrade. Like the book reference numbers in a public library.
