I'm looking forward to this tonight - they must be thrilled to bits with their find!
I'm ashamed to say I know little about Richard III, other than what may now seem to be popularised myths about him - if anyone can recommend a good read or documentary on him, I'd be very grateful.
Oh boy, the choice is huge. I can recommend Sharon Penman's "The Sun in Splendour" - it is a historical novel based on the events surrounding Richard and Edward IV - absolutely engrossing.
The first book I ever read on the story was Elizabeth Jenkins' "The Princes in the Tower". She says Richard, in all probability, had a hand in his nephews' demise but that there was no other option open to him if he hoped to survive. It is a very good read.
