On the evening of the twenty-ninth of April 1483 Anthony Woodville dined with Richard of Gloucester at Northampton. The sources describe the dinner as apparently amicable.
Edward IV died before anyone was ready for it. Elizabeth Woodville was ready within hours. She knew what the will said. She knew the threat a formal Protectorship posed to her family, and she knew the constitutional loophole that could render it void. She knew the coronation was the mechanism and the fourth of May was the date and speed was everything. What she did not know was that the information she was moving on was already moving against her, sent north in a sealed letter by a man who had been in the same room and drawn a different conclusion.
Edward IV died before anyone was ready for it. The Woodvilles were ready within hours. Richard of Gloucester did not know his brother was dead for ten days.
