I don't believe in fate. I don't believe in cushioning your insecurities with a system of belief that tells you 'Don't worry. This may be your life but you're not in control. There is something or someone looking out for you -- it's already organised.' It's all chance and choice, which is far more frightening.

When I worked at The Independent newspaper, I had colleagues who would laugh and say that whenever they picked up the phone to my dad and heard his accent, they thought they were about to hear a five-minute warning to get out the building. People in Britain have always thought it acceptable to make racist remarks about the Irish. The prejudice underlying that supposed joke was everywhere.

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.

I still have a stammer. I hate it; I loathe and despise it. But it's always there, and I have lots of ways to conceal it. I can conceal it now but I'm not good on the telephone. I get my husband to make dentist appointments. And I hate live radio. Hate it. I really try to avoid it at all costs. But it's always there. Stammerers become skilled at sentence construction and synonyms: we have to be. Faced with a problem word, we need to have instant access to eight others we could use instead - ones we could say without stumbling. I think my stammer is a huge part of my being a writer.

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.

People had tell me the most personal things. People I'd never met before would say thing like "Oh, that was the summer I had an affair with my neighbor." The 1976 heatwave occupies a peculiar place in people's psyches.

I think it was Rose Macaulay who said, "A house unkept cannot be so distressing as a life unlived."
