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.

Always, at the end of every book, there are things you will be unsatisfied with, and still more things that later on you will realize were not right. But mistakes are part of what a book is. That itchy, dissatisfied feeling at the end of a novel is useful. It's what keeps you writing and gets you writing the next one. It's what keeps you learning.

She wanted to say, no. She wanted to say, I have a son, there is a child, this cannot happen. Because you know that no one will ever love them like you do.

I met a retired police detective. And he said to me that the interesting thing about heatwaves, from a police perspective, is that the number of people who just walk out of their lives when the weather gets unbearable is astronomic. He said the police prepare themselves for it - for a huge rise in the instances of missing persons. People choose to disappear when it's hot. It was fascinating.

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.

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."
