It was a combination of an intense interest in children's literature, which I've always had, and the feeling that I'd just have a go and see if I could do it.
Since then, I have just read and read - but, that said, I suppose there is a raft of writers to whom I return again and again, not so much because I want to write like them, even if I were capable of it, but simply for a sort of stylistic shot in the arm.
The pleasure of writing fiction is that you are always spotting some new approach, an alternative way of telling a story and manipulating characters; the novel is such a wonderfully flexible form.
