I'm happier not pretending I know anything about El Cid in Spain. He's a Spanish national hero. I'd rather invent a character inspired by him but clearly not identical to him. And then I feel liberated creatively.

I'm still proud of the 'Fionavar Tapestry.' The fact I don't write the same way is as much as anything else the fact a man in his 50s doesn't write the way a man in his 20s does - or he shouldn't.

Do we value privacy in any real way? Thinking about blogs, Twitter, Facebook, MySpace... all these suggest we value exposure rather more. And instead of challenging this transformation, as they are supposed to - certainly at the more thoughtful edges of the art - novelists are buying into it wholesale.

Joe is the hero and Sammy is the sidekick. That's how I feel about it.

The very best way I can make any reader believe in the nuts and bolts of an art form... is to know the mechanics, to make the characters grounded in convincing detail.

And feel that I am happier than I know.
