Ooh. I don't usually dom ... but Jane Austin /and/ twisted religious fanaticism? I would be interested. I must admit, it's been a good year or two since I've read the book, so I'd want to re-read it, at least in part before I could really do the characters justice. As such, it might be a short while before I could, in all good conscience, agree definitively to your request. I am, however, writing to inform you that your request has not fallen upon deaf ears, nor a heart of stone. So color me interested, and I'll try to be less tenative and more helpful once I have a few days to re-read the book.
Lizzie would indeed, make a succubus, who must needs be /punished/ for her wickedness, and for inspiring such wicked thoughts from an otherwise righteous man.
