— Impossible to sustain a smoking habit in London these days. Bad news for brain.
— It's good news for breathing.
— Oh, breathing! Breathing's boring.

When you have eliminated the impossible whatever remains must be the truth.

— Because you're an idiot. No, no, don't look like that. Practically everyone is.

— That... was amazing.
— Do you think so?
— Of course it was. It was extraordinary, quite extraordinary.
— That's not what people normally say.
— What do people norrnally say?
— Piss off!

— Shut up, everybody! Don't move, don't speak, don't breathe. I'm trying to think. Anderson, face the other way. You're putting me off.
— What? My face is...?
— Everybody quiet and still. Anderson, turn your back.

War does not follow you, Dr. Watson. You are following her.

— Mrs. Hudson, the landlady, she’s given me a special deal. Owes me a favor. A few years back her husband got himself sentenced to death in Florida. I was able to help out.
— Sorry, you stopped her husband being executed?
— Oh, no, I ensured it.

Between you and me sitting here, why can't people think? Don't it make you mad? Why can't people just think?

— Are these human eyes?
— Put those back!
— They were in the microwave!
— It's an experiment.

— That's fantastic!
— Do you know you do it out loud?
— Sorry, I'll shut up.
— No, it's...fine..

— Mrs. Hudson, I'll be late. Might need some food.
— I'm your landlady, dear, not your housekeeper.
— Something cold will do.

— Both of you?
— Impossible suicides? Four of them? No point sitting at home when there's finally something fun going on!

— Taxi for Sherlock Holmes.
— I didn't order a taxi.
— Doesn't mean you don't need one.

— Seen a lot of injures, then. Violent deaths.
— Well, yes.
— Bit of trouble too, I bet?
— Of course. Yes. Enough for a lifetime, far too much.
— Want to see some more?
— Oh, God, yes.

— Hey, where did you get this? [Takes the ID card] Detective Inspector Lestrade?
— Yeah. I pickpocket him when he's annoying. You can keep that one, I've got plenty at the flat.

— Mrs Hudson's got a phone.
— She's downstairs. I shouted, but she didn't hear.
— I was the other side of London!
— There was no hurry.
