I spent part of my college years in a Marxist commune. I was not a Marxist. I wasn't even pretending to be one. I was a Marxist-in-law.

Sometimes, a novel is like a train: the first chapter is a comfortable seat in an attractive carriage, and the narrative speeds up. But there are other sorts of trains, and other sorts of novels. They rush by in the dark; passengers framed in the lighted windows are smiling and enjoying themselves.

When a novel has 200,000 words, then it is possible for the reader to experience 200,000 delights, and to turn back to the first page of the book and experience them all over again, perhaps more intensely.

Another thing I learned is that novels, even those from apparently distant times and places, remain current and enlightening, and also comforting.

Somehow, knowing that Alzheimer's is coming mocks all one's aspirations - to tell stories, to think through certain issues as only a novel can do, to be recognised for one's accomplishments and hard work - in a way that old familiar death does not.

With any novel that you begin, you can't foresee how difficult or easy it's going to be, and you can't really prepare yourself. You just have a take it one step at a time and know that it's all right to keep going - you can always fix it.

I love to write about sex. You just have to make it idiosyncratic. You have to have a strong comprehension of your characters, and write it from their point of view. It's really fun. It's not erotic.
