Oh, yes, absolutely a very thin premise, Harpgirl. I guess I meant that it is a novel that uses a lot of theories that I was not aware of, ie the Last Supper image, I did the same thing, really studied the painting online, and found it to be quite a logical thought that this person did, in fact, seem to be a woman.

I guess it was a book that made me spend an awful lot of time searching the internet about lots of things that I was not aware even existed.   Perhaps I live in an isolated world.
