I was poking around on Red Hen Publications, whose essays are a lot of fun, even if they verge on the absolutely absurd (in my opinion) and sometimes seem to be more attempts to justify fandom and fanfiction premises than straight analysis/speculation of the books, and I found an essay entitled "Loyaulte me lie". It's about Snape, or rather it's an elaborate Dumbledore-Snape Conspiracy Theory that is the most convincing one I've seen yet. But the important thing is obviously the title: I'm not the only one to want to associate Snape and Richard.
