Now, I - for several years while I was researching this book, I felt quite obsessed by thoughts about sentencing, punishment, how judges arrive at their decisions.

Tentatively I stood a great lump of wood on the chopping block and bought the axe down on it. It flew into two perfect halves. Such was my elation that I ran inside, put on our ancient cracked record of Aretha Franklin singing Respect and danced all by myself for half an hour in our living room, without inhibition, almost crying with jubilation – not just about the wood, but because I could live competently some of the time, and because that day I liked myself.

Well, I'm at some kind of crossroads in my life and I don't know which way to take. It's not about money, I mean, because I'm established enough now as a writer to get a reasonable advance if I wanted to do fiction.

I'm full of restlessness. Not lonely, exactly - my head is racing with ideas. But it is that old treacherous feeling that real life is happening somewhere else, and I'm left out.

We were in a great, seething moment in the 1970s. There was a new Labour government and everything seemed full of hope... But, as we got older and we saw how much women's behaviour contributed to what was wrong, we stopped being able to see ourselves purely as.

People demand a lot of the justice system and they demand things that it can't deliver.

I suppose there must be idiots who dream of signing deals with publishers while fully intending to drink martinis in cool bars or ride around on skateboards. But the actual writers I know are experts in neurotic self-torture. Every page of writing is the result of a thousand tiny decisions and desperate acts of will.
