Rewrite the history books? I don't think so. Everything that's been leaked so far simply confirms the traditional story: Here's a man with a spinal deformity who died in battle and has turned up in exactly the right place. Oddly enough the Tudor historians turn out to have been trustworthy- in so far as their record can be checked.
As for information about who Richard really was- and whether he was guilty of the crimes laid at his door, well, we'll have to go to the Akashic records for that.
Even so I'm looking forward enormously to the Channel 4 documentary. I love old bones (any old bones.)
Also (I'm not entirely sure of my reasons) I love Richard.
