I think it's the natural way for me to write, the way I write naturally, but I think in some of the books, especially in some of the earlier ones, there is a certain amount of writing that isn't dialogue. But, my books seem to me to be something between a novel and a play. (p. 165)

[But the form of the novels] isn't exactly the structure of a play. It's longer than a play, isn't it, and gives me more scope than a play would. I think I should find the actual performance of a play, a play that has to be acted on the stage, too short. Though my books are short compared with some books, if you don't put any descriptive writing in, the book must be short as regards the number of words, but I think I should find the distinct form of a play...
