From "About the Author" in Heritage:
Dale Smith is an award-winning playwright. I know, you wouldn't believe it, would you? Be he had plays in London, Northampton, Manchester and Edinburgh. And he's shaken Melvyn Bragg's hand. But don't get too excited: he used to have a pony-tail.
Oh, and people seemed to like his two Brief Encounters for DWM.
He spends a lot of time sleeping. It keeps him happy.
