The vast majority of writers out there, they finish their books, and no one cares whether their book is late or ever comes out at all. And then it comes out, and two reviews are published, and it sells 12 copies.
As far as I'm concerned, an audience is an audience. Whether it's an audience in Hull or the National Theatre, that's who you play to. It's not money - it's good to get some, but that's not why I do it. You do it because you have to, to tell a story.
