Maybe this is pathetic, but I still dread producing a book that doesn't earn back its advance. I hate obligations that are financially foggy.

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.

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.

I think that there must be a point of self-immersion in a story that is a point of no return. You get far enough in that the story has really touched you to the core and deeply troubled you and made you unhappy and fearful, and then how do you get out of that? I'm a writer, so my way of getting out of that is to write.
