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.

I try not to be too precious about my writing, and I try to be willing to walk away from it for a few hours when something's not working, to let things percolate a bit. I try not to hide myself away from life too much, because I think that's a risky thing for a writer to do.

As you'll know yourself, there are these moments when you're writing a book when one remark or moment will pull everything together and you'll think, "That's it. I've got what I need."

I have no control, of course, over how I'm marketed. It's a sad thing, though, that so many people perceive literature to be gendered. The idea that some subjects are male and some are female is just preposterous to me. It's reductive and nonsensical, to separate writers and subjects and plots along gender lines. It's meaningless.

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 always had the urge to write. Not in the sense of wanting to be a writer, but just writing things down, getting words on a page. Graphomania, it's called. I've always had a definite love of stationary products - I used to spend all my pocket-money on pens and notepads. I still do, in a way.

Spending a lot of time away from home was strange. My parents visited me, obviously, but I was in hospital a lot, alone. And then when my health had improved a bit and I was in a sick-bed in the house, with the life of the house going on around me, that was very vivid for me. I always think that's a bit like the position of a novelist in a novel, going through drafts: there but not there, one remove from reality.
