Despite being from Ireland, I've always avoided writing about it, for two reasons. For a very small country, Ireland has produced an astonishing number of literary geniuses, and at some level I probably never felt, having left as a toddler, that I had the right to try and add my voice. That's part of it. But I also didn't want to write something that was the equivalent of the Irish theme pub. You find them all over the world. The idea of producing a novel that might replicate that type of ersatz really set my teeth on edge.

All the time I was plowing through books on dyslexia, I found myself asking: what if, what if? What if you were a kid the 1950s with this condition, when there were no books on it, when there was no understanding of it. I remember kids in my class at school who just didn't seem to progress in their reading. There was no extra help. People just thought, "Oh, he or she isn't so bright, or they're obstinate."

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.

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.

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.

Why isn't life better designed so it warns you when terrible things are about to happen?

There was so much anti-Irish sentiment not just from other kids at the school I went to in Britain, but also the teachers themselves. I remember very clearly a lot of the things people said to me and my sisters. And of course those sentiments go back a long way. When my dad visited London in the 50s and was looking for somewhere to stay, there were signs outside boarding houses that said "No blacks, no Irish."
