I have two sisters, and I think siblings are always going to be irresistible for novelists. They have been throughout time and they'll continue to be.

Something that had an enormous influence over my relationship with language was my stammer. I had a really bad stammer in my childhood and adolescence, and that imbues you with two things. First, a hyper-sensitivity to grammar, because a stammerer will have problematic sounds, impossible verbal stumbling blocks. Second, writing is just such a joy when you have a problem with speaking. It's so astonishing to watch language coming out of your pen without any hesitation or dysfluency.

I don't want to be influenced as to what I write in the next book, to hear those voices in my head when I'm writing. The idea of second-guessing your reader is dangerous, trying to please some notional reader looking over your shoulder, instead of just yourself.

As other authors have realized, heat can have a strange effect on us, can cause odd chemical reactions in the brain. Heat can bring out secrets; it can change people's personalities.

I have two sisters, and I think siblings are always going to be irresistible for novelists. They have been throughout time and they'll continue to be.

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.

For a while I used to listen to those whispers about babies costing you books, and Cyril Connolly's loathsome quote that "There is no more somber enemy of good art than the pram in the hall." But it's rubbish. Absolute rubbish. A huge amount of your work is done when you're not at your desk. Knotty problems that you need your unconscious to solve. So it can be helpful to walk away and focus on other things and it can be helpful to be a bit harassed in your daily life, to be hungry for time to write.
