Richard III
I recently picked up a biography of him and have been researching him on the Net. I'm trying to decide for myself whether or not he murdered his nephews. No success as of yet. I have included below a bibliography and some interesting Richard links. It doesn't really matter at this point if he did kill the Princes in the Tower or not, since they are all long dead. Though I'd like to know...But Richard led an intriguing life, and if you're interested in Medieval England at all, I think you'll find these sites enjoyable.
