Arthur, who has to stay with us until we can be certain of the safety of Wales, is torn between his studies and the view from the high window, where he can see his father’s army growing in numbers, drilling every day. Every day too he sees messengers coming from the west, bringing news from Ireland or from Wales, or from the south—from London, where the streets are buzzing with gossip and the apprentices are openly wearing white roses.

In the afternoons I take him riding with me but after a few days Henry forbids us to go out without a fully armed guard. “If they were to snatch Arthur then my life wouldn’t be worth a groat,” he says bitterly. “The day that he and Harry die is the day of my death sentence and the end of everything.”

“Don’t say that!” I put out my hand. “Don’t ill-wish them!”

“You’re tenderhearted,” he says grudgingly, as if it is a fault. “But foolish. You don’t think, you don’t realize what danger you are in. You cannot take the children out of the castle walls without a guard. I am beginning to think that they should be housed separately—so that anyone coming for Arthur couldn’t get Henry.”

“But my lord husband,” I say. I can hear the quaver in my voice, I can hear the whine of reasonableness against the clarity of a madman.

“I think I’ll keep Arthur in the Tower.”

“No!” I scream. I cannot contain my shock. “No, Henry. No! No! No!”

“To keep him safe.”

“No. I won’t consent. I can’t consent. He’s not to go into the Tower. Not like . . .”

“Not like your brothers?” he asks, quick as a striking snake. “Not like Edward of Warwick? Because you think they are all the same? All boys who might hope to be king?”

“He is not to go into the Tower like them. He is the proclaimed prince. He must live freely. I must be allowed to ride out with him. We cannot be in such danger in our own country that we are prisoners in our own castles.”

His head is turned away from me so I cannot see his expression as he listens. But when he turns back I see his handsome face is twisted up with suspicion. He looks at me as if he would flay the skin from my face to see my thoughts.

“Why are you so determined upon this?” he asks slowly. Almost, I can see his suspicions gathering. “Why are you so determined to keep your sons here? Are you riding out with Arthur to meet with them? Are you hoodwinking me with this talk of safety and riding out? Are you planning to take my son out to hand him over? Are you working with the Yorks to steal my son from me? Have you made an agreement? Forged a deal? Your brother as king, Arthur as his heir? Will you put Arthur in his keeping now, and tell him to invade as soon as the wind turns against me and he can sail?”
