Editing Princes in the Tower (section)

===Other suspects===
Some scholars have instead accused [[John Howard, 1st Duke of Norfolk]], [[Margaret Beaufort, Countess of Richmond and Derby|Margaret Beaufort]] (Henry VII's mother), or [[Jane Shore]] (Edward IV's mistress). The Beaufort theory was supported by [[Philippa Gregory]] in a 2013 BBC documentary series ''The Real White Queen and her Rivals'',<ref>{{cite web|last1=Gregory|first1=Philippa|title=Philippa Gregory tells the true story behind The White Queen|url=http://www.radiotimes.com/news/2013-06-16/philippa-gregory-tells-the-true-story-behind-the-white-queen|website=Radio Times|publisher=The Radio Times (BBC)|access-date=2 June 2014}}</ref> However, it has been sustained only by speculation about a possible motive, rather than evidence.<ref name="Jonathan Cape"/> Pollard has commented regarding such theories: "None deserve serious consideration. The problem with all these accusations is that they beg the question of access to the Tower without Richard's knowledge and overlook the fact that Richard was responsible for the safekeeping of his nephews".<ref>Pollard p 127</ref>
