“Then Henry will find nothing in his search of the Tower,” she observes. “If Richard did not kill them, there will be no bodies for Henry to bring out. Perhaps they are both alive, hidden somewhere in the Tower or in the houses nearby.”

“And what would Henry do then? If he found them alive?” I am breathless at this speculation. “What would he do if someone came forward and said they had them hidden, safely hidden away, our boys, for all this long time?”

My mother’s smile is as sad and as slow as a falling tear. “Why, he’d have to kill them,” she says simply. “If he were to find my sons alive now, he would kill them at once, and blame it on Richard. If he found my sons alive, he would have to kill them, to take the throne, just as your father killed old King Henry to take the throne. Of course he would. We all know that.”

“And would he do it, do you think? Could he do such a terrible thing?”

She shrugs. “I think he would make himself do it. He would have no choice. Otherwise, he would have risked his life and his army for nothing. His mother would have spent her life plotting and even marrying for nothing. Yes, if Henry ever finds your brother Edward alive he would kill him in that moment. If he finds your brother Richard he would have to put him to death. It would be nothing more to him than continuing the work he did at Bosworth. He’d find some way of settling his conscience. He’s a young man who has lived under the shadow of the sword from the moment when he fled England as a boy of fourteen to the day when he rode home to fight for his claim. Nobody knows better than he that any claimant to the throne has to be killed at once. A king cannot let a pretender live. No king can allow a pretender to live.”

Henry’s court goes with him to the Tower, and more and more men flock to the Tudor standard now that it is triumphant. We hear, through gossip from the city streets, of the round of rewards that comes from the Tudor throne as Henry hands out the spoils of Bosworth in the days before his coronation. His mother has all her lands and wealth returned to her; she enters a greatness that she always claimed but never enjoyed before now. Her husband, Thomas, Lord Stanley, is made Earl of Derby and High Constable of England, the greatest position in the realm, as reward for his great courage in looking both ways at once, the two-faced traitor that he is. I know, for I heard him swear the oath, that he promised his loyalty, his absolute fealty, to my Richard; I saw him go down on his knees and promise his love, even offering his son as a pledge of his loyalty. He swore that his brother, his whole family, were Richard’s true men.
