Sherlock

— If this woman's death was suspicious, why point it up?
— Good Samaritan.
— Who press-gangs suicide bombers?
— Bad Samaritan.

What now? I'm in shock — look, I've got a blancket. And I just caught you a serial killer.

In the world of locked rooms, the man with a key is king. And honey, you should see me in a crown.

— He's got on with his life.
— What life? I've been away.

[Looking at the mannequin hanging by the throat]
— So did you just talk to him for a really long time?

— We found the case. According to someone, the murderer has the case, and we found it in the hands of our favourite psychopath.
— Not a psychopath, I'm a high-functioning sociopath. Do your research.

— What the hell are you doing here?
— Oh, nice to see you too!

— Did he offer you money to spy on me?
— Yes.
— Did you take it?
— No.
— Pity, we could have split the fee. Think it through next time.

You do see, you just don't observe.

— There's a woman lying dead.
— Perfectly sound analysis, but I was hoping you'd go deeper.

— That was the doorbell. Couldn't you hear it?
— It's in the fridge. It kept ringing.
— Oh, that's not a fault, Sherlock!

Intuitions are not to be ignored. They represent data processed too fast for the conscious mind to comprehend.

Every fairytale needs good old-fashioned villain.

— Now, serviettes... Swan or Sydney Opera House?
— Where did you learn that?
— Many skills are required in the field of criminal investigation.
— Fibbing, Sherlock.
— I once broke an alibi by demonstrating the exact severity of a fold...
— I'm not John, I can tell when you're fibbing.
— OK, I learn it on YouTube.

Dangerous to jump to conclusions.

— You look taller in your photographs
— I take the precaution of a good coat and a short friend.
