I read The Collector a long time ago. It's a really creepy book and I thought at the time it was almost a manual of "How I'd do it if I did". I have just been leaving through CraigBrown's 99 Glimpses of Princess Margaret left lying around at work. Apparently John Fowles was just one of many admirers, including Picasso who had fantasies about her. His dark fantasy and inspiration for the book repulse me. I wonder if it is a common fantasy? (Not necessarily with the Princess as the object of desire).
