Benjamin Black is a craftsman and these are crafted works. I'm very proud of them. I think they're well made, but Banville is doing something else – he's trying to make a kind of poetry, I suppose. I'm a perfectionist. It's an illness but a good illness. It's a completely different method of writing. Banville writes with a fountain pen on paper in a manuscript book and Black works straight on to the screen. It could take me a whole morning to write a few sentences as Banville, but as Black I'd be very annoyed if I didn't have at least two or three pages done. This drives crime-writers crackers because they think I'm saying that their craft is not worth it. I'm simply saying it's a different thing. I don't know why they worry when I talk about speed; after all, Georges Simenon wrote his books in about 10 days.
