Watson: We've only just met and we're going to go look at a flat.
Sherlock: Problem?
Watson: We don't know a thing about each other. I don't know where we're meeting. I don't even know your name.
Sherlock: I know you're an army doctor and you've been invalided home from Afghanistan. I know you've got a brother who's worried about you, but you won't go to him for help because you don't approve of him—possibly because he's an alcoholic, more likely because he recently walked out on his wife. And I know that your therapist thinks your limp's psychosomatic, quite correctly I'm afraid. That's enough to be going on with, don't you think? he exits and pops back in. The name's Sherlock Holmes and the address is 221b Baker Street. Afternoon.

Sherlock: You're a doctor. In fact you're an army doctor.
Watson: Yes.
Sherlock: Any good?
Watson: Very good.
Sherlock: Seen a lot of injuries then. Violent deaths.
Watson: Well. Yes.
Sherlock: Bit of trouble too I bet.
Watson: Of course. Yes. Enough for a lifetime. Far too much.
Sherlock: Wanna see some more?
Watson: Oh god yes.

Watson about Sherlock's deductions: That. Was amazing.
Sherlock: You think so?
Watson: Of course it was. Extraordinary. It was quite extraordinary.
Sherlock: That's not what people normally say.
Watson: What do people normally say?
Sherlock: "Piss off".

Sherlock: We've got ourselves a serial killer. Love those—there's always something to look forward to.

Baker Street. Come at once if convenient. SH
If inconvenient come anyway. SH

Watson: That was ridiculous. That was the most ridiculous thing I've ever done.
Sherlock: You invaded Afghanistan.

Anderson: According to someone, the murderer has the case and we found it in the hands of our favorite psychopath.
Sherlock: I'm not a psychopath, Anderson. I'm a high-functioning sociopath. Do your research.

Sebastian: There's a hole in our security. Find it and we'll pay you. Five figures. This is an advance. Tell me how he got in, there's a bigger one on its way.

Watson: I went to see about a job at that surgery.
Sherlock: How was it?
Watson: Great. She's great.
Sherlock: Who?
Watson: The job.
Sherlock: "She."
Watson: "It."

Sherlock: The world's run on codes and ciphers, John. From the million pound security system at the bank to the PIN machine you took exception to. Cryptography inhabits our every waking moment.

Watson: Where are we headed?
Sherlock: I need to ask some advice.
Watson: What? Sorry?
Sherlock: You heard me perfectly, I'm not saying it again.

Watson: Two men back from China. Both head straight for the Lucky Cat Emporium. What did they see?
Sherlock: It's not what they saw. It's what they both brought back in those suitcases.
Watson: You don't think duty-free.
Sherlock: Think about what Sebastian told us, about Van Coon, about how he stayed afloat in the market.
Watson: "Lost five million."
Sherlock: Made it back in a week. That's how he made such easy money.
Watson: He was a smuggler.

Sherlock: I see you've written up the taxi driver case.
Watson: Uh, yes.
Sherlock: "A Study in Pink". Nice.
Watson: Well, you know. A pink lady, pink case, pink phone. There was a lot of pink. Did you like it?
Sherlock: Um... no.
Watson: Why not? I thought you'd be flattered.
Sherlock: Flattered? "Sherlock sees through everyone and everything in seconds. What's incredible though is how spectacularly ignorant he is about some things."
Watson: Now hang on minute, I didn't mean that in a—
Sherlock: Oh! You meant "spectacularly ignorant" in a nice way.

Sherlock: I've been summoned. Are you coming?
Watson: If you want me to.
Sherlock: Of course. I'd be lost without my blogger.

Watson: That's the phone— the pink phone.
Lestrade: What, from A Study in Pink?
Sherlock: Well obviously it' s not the same phone. But it's supposed to look like— "A Study in Pink"? You read his blog?
Lestrade: Of course I read his blog. We all do. Do you really not know that the Earth goes around the sun?

Sherlock: The curtain rises.
Watson: What?
Sherlock: Nothing.
Watson: No, what did you mean?
Sherlock: I've been expecting this for some time.

Lestrade: There's something else that we haven't thought of.
Sherlock: Is there?
Lestrade: Yes. Why is he doing this, the bomber? If this woman's death was suspicious why point it out?
Sherlock: Good Samaritan.
Lestrade: Who press-gangs suicide bombers?
Sherlock: Bad Samaritan.

Lestrade: Any ideas?
Sherlock: Seven. So far.

Watson: Any time you want to explain?
Sherlock: Homeless network.
Watson: Homeless network?
Sherlock: My eyes and ears all over the city.
Watson: That's clever. So you scratch their backs and...
Sherlock: Yes. And then disinfect myself.
