The more I researched this book, the more research I had to do. All the experts disagree, and there's little fact left to be found. Henry Tudor rewrote history when he defeated Richard Plantagenet. And Richard, in turn, did some fancy rewriting when he took over from his brother Edward, declaring Edward's two sons illegitimate.

I'd read Josephine Tey's Daughter of Time and for years firmly believed Richard III to be innocent of the crime of killing his nephews, the two princes in the tower. But after spending months reading and then chasing all over England looking for clues, I have to admit that now I think Richard probably done the dark and dirty deed. (Not himself, of course. Like most pragmatic politicians, he had someone else do it so he could deny it later.)

Luckily for me, this is a romance, and not really about Richard, so whether or not he was guilty doesn't influence the book at all.

But does the argument interest you? You can nip over to the Richard III society and take a look at their site. (They probably won't let me in now!)
