I don't think you're happier if you're thin or beautiful or rich or married. You have to make your own happiness. My heroines do not become beautiful elegant swans, they become confident ducks and get on with life.

I love thriller writers. My favourites are Harlan Coban, Lee Child, Ian Rankin, Kathy Reichs and Ed McBain.

I'm pleased to have outsold great writers. But I'm not insane - I realize I am a writer people buy to take on vacation.

I didn't get excited by weight loss, and since I was already happy being fat, I couldn't see the point of it all. I'm 6 ft. and weigh about 18 st. or 19 st., but weighing myself is not something I do with much pleasure.

If I had my life to live all over again, I really think I would have been a fit person. Looking around me, I realise that the men and women who walked and ran and swam and played sport look better and feel better than the rest of us.

The most important thing to realize is that everyone is capable of telling a story.

You say to yourself: 'What could people, in all these countries, find in my books?' and yet I think we're all the same, anywhere. Everybody is a hero or a dramatic person in their own story if you just know where to look.
