“She cannot have wealth and influence,” Lady Margaret says. “She would use it against your husband and your son. I know that you love her dearly, but, Elizabeth—she has become your enemy. She is no mother to you and your sisters anymore. She was providing funds to the men who hope to throw down the Tudor throne; she was giving them advice, sending them messages. She was plotting with Duchess Margaret, who is mustering an army. She was living with us, playing with your child, our precious prince, seeing you daily, and yet working for our destruction.”

I rise from my chair and go to the window. Outside the first swallows of summer are skimming along the surface of the river, twisting and turning in flight, their bellies a flash of cream as if they are glad to be dipping their beaks into their own reflections, playing with the sweet water of the Thames. I turn back. “Lady Margaret, my mother is not dishonorable. And she would never do anything to hurt me.”

Slowly she shakes her head. “She insisted that you marry my son,” she says. “She demanded it, as the price of her loyalty. She was present at the birth of the prince. She was honored at his christening, she is his godmother. We have honored her and housed her and paid her. But now she plots against her own grandson’s inheritance and strives to put another on his throne. This is dishonorable, Elizabeth. You cannot deny that she is playing a double game, a shameful game.”

I put my hands over my face, so that I can shut out her expression. If she looked triumphant I would simply hate her, but she looks horrified, as if she feels, like me, that everything we have been trying to do is going to be pulled apart.

“She and I have not always agreed.” She appeals to me. “But I did not see her leave court with any pleasure. This is a disaster for us as well as for her. I hoped we would make one family, one royal family standing together. But she was always pretending. She has been untrue to us.”

I can’t defend her; I bow my head and a little moan of horror escapes through my gritted teeth.

“She’s not at peace,” Lady Margaret concludes. “She is going on and on fighting the war that you Yorks have lost. She’s not made peace with us, and now she’s at war with you, her own daughter.”

I give a little wail and sink down in the window seat, my hands hiding my face. There is a silence as Lady Margaret crosses the room and seats herself heavily beside me.

“It’s for her son, isn’t it?” she asks wearily. “That’s the only claim she would fight for in preference to yours. That’s the only pretender that she would put against her grandson. She loves Arthur as well as we do, I know that. The only claim she would favor over his would be that of her own son. She must think that one of her boys, Richard or Edward, is still alive and she hopes to put him on the throne.”
