I think all families have these secrets, and it's sometimes the strangest things that bring them out. That was part of my interest in the heatwave, in heat as a catalyst for uncovering truths. I was reading Alice in Wonderland to one of my kids recently, and I remembered that it starts on a really hot day. Alice falls asleep because of the heat; the whole story is predicated on falling into a heat-fueled dream.

We all have a family, whether we like it or not; we all come from somewhere, and there's something strange in the way you have, with siblings, two or three personalities yoked together for life. You grow up thinking those family relationships are set in stone and then you get older and realize they're not. They're always shifting.

I think it's dangerous to have lots of time on your hands as a writer. Time to pursue every little alleyway, to follow every single whim. I feel I've done my best writing when I'm stretched for time, when you're most pressured.

We're much better at dealing with dyslexia today than in 50th, but reading difficulties are still a problem in the U.K. I believe there's currently something like eleven thousand functionally illiterate adults in the U.K.

You need a lot of energy to get a novel finished. You need an ability to ignore everyone around you. It's why I don't read my reviews any more. I know a lot of people say that, but I really don't read them.

You learn so much with each book, but it's what you teach yourself by writing your own books and by reading good books written by other people - that's the key. You don't want to worry too much about other people's responses to your work, not during the writing and not after. You just need to read and write, and keep going.

When my family moved from Ireland in the 70s, Britain was such a difficult place to be Irish. It was a decade of real social and economic upheaval in Britain. There were strikes, the three-day week, the oil crises, huge inflation, the winter of discontent and, what was it, four Prime Ministers? And relations between Britain and Ireland at that time were at an all-time low. I was born in the year of Bloody Sunday and of course the pub bombings happened in the mid-1970s.
