“My other fascination was with the Nazis and their search for the Holy Grail. There was this theory that they had come to England at some point before the war to Glastonbury to try to find the Holy Grail. It was this Arthurian need, this search for a mythological link with God. But somewhere along the line it was perverted by what I was reading and what I was drawn to. And it was nobody’s fault but my own.”
