The main feature of interest in the field of criminal investigation is not the sensational aspects of the crime itself but rather, the iron chain of reasoning from cause to effect, that reveals, step-by-step, the solution. That's the only truly remarkable aspect of the entire affair.
You'd be amazed what a receptionist picks up. They know everything.
It's difficult having such good friends. Friends are people you want to share with. Friends and family. What's the very worst thing you can do to your very best friends? Tell them your darkest secret. Because, if you tell them, and they decide they rather not know... You can't take it back. You can't unsay it. Once you've opened your heart, you can't close it again.
Breakfast has got to be cool. You know what makes it cool when you're a kid? Dangerous.
— There is, in this facility, a prisoner whose intellectual abilities are of occasional use to the British government.
— What, for, like, really difficult sums, long division, that sort of thing?
— She predicted the exact dates of the last three terrorists attacks on the British mainland after an hour on Twitter. That sort of thing.

— How do you capture a serial killer?

— No, no. But most killers kill someone they know. You're looking for a murderer in a tiny social
grouping. <...> Serial killers choose their victims at random. Surely that must make it more

dummy. You only catch the dumb ones. Now, imagine if the Queen wanted to kill some people.
What would happen then? All that power, all that money, sweet little government, dancing
attendants. A whole country, just to keep her warm and fat. We all love the Queen, don't we? And
I bet she'd love you lot...
— It's all right, everyone. I can personally assure you that Sherlock Holmes is not about to arrest
the Queen.
— Well, of course not. Not Her Majesty. Money. Power. Fame. Some things make you untouchable.
God save the Queen!

— I'm Sherlock Holmes. I wear the damn hat.
— If you ever think I'm becoming a bit full of myself, cocky or overconfident...
— Yes?
— Will you just say the word, "Norbury" to me? Would you?
— Norbury?
— Just that. I'd be very grateful.
