My dad had this philosophy that if you tell children they're beautiful and wonderful then they believe it, and they will be. So I never thought I was unattractive. But I was never one of the girls at school who had lots of boyfriends.

I want any excuse to come home. My dad is not a spring chicken any more. If anyone says, 'Go buy a postage stamp in London,' I'll go and do it.

I never felt I was quite the ticket academically. I always felt I had to put in an enormous amount of effort not to be disappointing. So I worked really hard, but at the time it suited me, because I didn't do very much else.

I'm a dual citizen, as are my husband and children. We have got eight passports between us; we're weighed down by them whenever we go anywhere.

I am a good mother and I feel proud about it.

I spent a lot of time with a real detective, a lady detective inspector who was the only female detective inspector in the whole of East London. She and I hung out a lot. She showed me what she did and I spent time with her. So, [she was] a lot of the inspiration for the way I dressed and sometimes the dialogue in those interview scenes where we're cross examining and questioning the youths and trying to get a confession out of them.

There were moments where I was being kicked in the stomach, and even though I had this brace on to protect me, I still had to prepare myself for it . You can't be relaxed when that's happening. You have to brace your muscles. I can remember thinking as it was about to happen "Wasn't that how Houdini died?" I think it was.
