My idea in Half the Kingdom was simply, or not so simply perhaps, that medical science has given us twenty extra years of life. Those twenty extra years - one is grateful for them, one is happy, but they also give you ten or twenty years more of losing your faculties. That is actually the origin of my notion. Once you live longer than you're supposed to live, things go dreadfully wrong. But nevertheless, you're not dead.

I'm very moved and very excited. And it just seems to me here are houses and trees and streets that feel so different from New York. I feel very attached to London; I love it.

Franz Kafka is a huge influence, more than the Grimms. To allow yourself to get into the coal bucket and fly to the sky ... we learned that from Kafka, that you can have a thought and make a body of it in this way.

It's hard for us sophisticates to believe, but the people my parents worked for were good people. They were socialists of the heart. They were Scottish upper class. I don't think they had political theories in the way my lefty friends in New York do but they did all the things that socialists do. My mother was the Jewish cook from Vienna and they would say, "Come and have dinner with us." I spent weekends with them. Who does that? This is Utopia.

Once you start on an idea it proliferates in itself.

I'm not going to say it's laziness, but I'm not a grand creator of new characters.
