I've long stopped reading any new "revelations" about this particular issue - and with a good reason, which has been now confirmed once again. Say what you want about Philippa Gregory's novels (not a fan myself), but she isn't so much more ridiculous than many of these authors, for reasons Alison H listed. To me, she ranks somewhere around the level of Josephine Tey who wanted to absolve the princes' mother from the suspicions that she had made peace with her sons' and brother's murderer for some money and a few balls. Err, a name conspicuously missing from the list of this author who all lay Richardians I've ever encountered swear by? Richard Grey, people?
