Hugely excited by the discovery of Richard III’s skeleton in Leicester, I was keen to see the documentary relating how the skeleton was verified. And although i didn’t find the programme particularly satisfying, some of the facts were. It was interesting, for example to see that he did have a significantly deformed spine, but no withered arm.

At the same time I saw a post regarding Mary Ingalls’ blindness (Little House on the Prairie) – fascinating stuff.

So what ‘facts’ presented in historical fiction would you like to have examined / verified?
