And who was prompting that gossip? The same usurper. Like I said, Henry’s claim that Richard killed them was awfully politically convenient. In any case, he was the last to see them alive, so he would know, right?
Where are you getting that Henry was the last to see the princes alive? He was in France from 1471 until he landed with his army in 1485. The princes hadn’t been seen in two years at that point.
