You know, we're each the hero of our own story and we perceive what's going on around us, and especially in a relationship, from the kind of viewpoint of, 'Well, this is my story, and I'm the hero of that, and I justify what I do around it.'

I think 'Tattoo''s a song that can go so many different ways. Some people think of it as a break-up song, but, for me, it's about somebody who comes into your life and really touches you - be they a friend, a family member or someone you're in a relationship with.

If you love somebody, you love them. My parents had a 25-year age gap between them and my mum was the breadwinner, my dad the house husband. I'm a strong believer that a good relationship can work, whatever the situation.

I'm so single. It's funny. I'm usually a relationship girl. I love being in love and having a partner in crime. But it's good to be your own partner in crime. God, that makes me sound like I have multiple-personality disorder.

But I think the real tension lies in the relationship between what you might call the pursuer and his quarry, whether it's the writer or the spy.
