I discovered that my imagination came alive when I moved away from the immediate world around me.

I had been plunged into a different world. I found myself spending half my time answering weird questions on book tours in the Midwest. People would stand up and explain to me the situation in their office and ask me whether they should resign or not.

He chose a certain path in life, it proved to be a misguided one, but there, he chose it, he can say that at least. As for myself, I cannot even claim that. You see, I trusted. I trusted in his lorship's wisdom. All those years I served him, I trusted I was doing something worthwhile. I can't even say I made my own mistakes. Really - one has to ask oneself - what dignity is there in that?

I still have a suspicion of charity and think the state has a role to play in many areas. And although for most of the years since I have been a rather privileged writer, I identify more closely than perhaps I should with those social workers. Had I not become a writer that would have been me. Lots of our friends are still in that world and I do feel part of that generation of people who were rather idealistic in the 70s and became disillusioned in the 80s. Not just about social services issues, but the world.

After all, what can we ever gain in forever looking back and blaming ourselves if our lives have not turned out quite as we might have wished?

I couldn't speak Japanese very well, passport regulations were changing, I felt British and my future was in Britain. And it would also make me eligible for literary awards. But I still think I'm regarded as one of their own in Japan.

I really have to think of the things fiction can do that film can't and play to the strengths of the novel. With a novel you can get right inside somebody's head.
