History of Norfolk — Chapter 22
“ CHAPTER XXII Of the city in Richard the third's time Richard Duke of Gloucester seized the crown as aforesaid, June 23, 1483, and having secured himself (as he supposed) by the murder of his two nephews, thought he should meet with none that dare oppose him; but far was he out of his calculation, for he never enjoyed any ease in his whole life, after he was King. ”
