The struggle between the Light and the Dark in my books has more to do with the fact that when I was four World War II broke out. England was very nearly invaded by Germany, and that threat, reinforced by the experience of having people drop bombs on your head, led to a very strong sense of Us and Them. Of course Us is always the good, and Them is always the bad. This sense must have stayed with me, and it put me into contact with all the other times that England has been threatened with invasion. We are such mongrels: we have been invaded over and over and over again from Scandinavia, from Ireland, from the Continent. This same fear and resistance--usually unsuccessful-- has been repeated throughout British history. All that goes into the collective subconscious, and, especially if you come from a generation which went through this experience in childhood, it becomes very much a part of your own imagination. So there is this sympathetic link between my growing up and what it must have been like when the real Arthur--what we know about him--was alive. You find this reflected in the books, especially the last. [1989 interview]
