I'm very disturbed by violence against women when it is violence.

The only thing that I was equipped for with my very mediocre college Arts degree was to get a job in teaching.

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.

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.

But I now think what I was doing, in a completely unconscious way, was getting off the turf where my husband and I might be rivals. We were both working in fiction... so I look back and I see that I consciously vacated the contested ground.

I think some people wished I'd kept myself out of the book. But I kind of insist on it because I want the reader to share my engagement with the material, if you like, not pretend that I'm doing it completely intellectually.

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.
