Sherlock, Series 2

Sherlock Holmes:
Nothing in the Bank of England, the Tower of London or Pentonville Prison could possibly match the value of the key that could open all three.

Moriarty:
I can open any door, anywhere with a few tiny lines of computer code. No such thing as a private bank account now. All are mine. No such thing as secrecy. I OWN secrecy. Nuclear codes? I could blow up NATO in alphabetical order. In a world of locked rooms, the man with the key is king. And honey, you should see me in a crown.
