‘You must not blame yourself. Your master will know you did all you could. After all, you are sent here to watch the king, you cannot be too long from London in the winter.’

He thinks, I have been there since Katherine’s trials began: a hundred scholars, a thousand lawyers, ten thousand hours of argument. Almost since the first word was spoken against her marriage, for the cardinal kept me informed; late at night with a glass of wine, he would talk about the king’s great matter and how he saw it would work out.

Badly, he said.

‘Oh, this fire,’ Chapuys says. ‘Do you call this a fire? Do you call this a climate?’ Smoke from the wood eddies past them. ‘Smoke and smells and no heat!’

‘Get a stove. I’ve got stoves.’

‘Oh, yes,’ the ambassador moans, ‘but then the servants stuff them with rubbish and they blow up. Or the chimneys fall apart and you have to send across the sea for a man to fix them. I know all about stoves.’ He rubs his blue hands. ‘I told her chaplain, you know. When she is on her deathbed, I said, ask her whether Prince Arthur left her a virgin or not. All the world must believe a declaration made by a dying woman. But he is an old man. In his grief and trouble he forgot. So now we will never be sure.’

That is a large admission, he thinks: that the truth may be other than what Katherine told us all these years. ‘But do you know,’ Chapuys says, ‘before I left her, she said a troubling thing to me. She said, “It might be all my fault. That I stood out against the king, when I could have made an honourable withdrawal and let him marry again.” I said to her, madam – because I was amazed – madam, what are you thinking, you have right on your side, the great weight of opinion, both lay and clerical – “Ah but,” she said to me, “to the lawyers there was doubt in the case. And if I erred, then I drove the king, who does not brook opposition, to act according to his worse nature, and therefore I partly share in the guilt of his sin.” I said to her, good madam, only the harshest authority would say so; let the king bear his own sins, let him answer for them. But she shook her head.’ Chapuys shakes his, distressed, perplexed. ‘All those deaths, the good Bishop Fisher, Thomas More, the sainted monks of the Charterhouse…“I am going out of life,” she said, “dragging their corpses.”’

He is silent. Chapuys crosses the room to his desk and opens a little inlaid box. ‘Do you know what this is?’

He picks up the silk flower, carefully in case it falls to dust in his fingers. ‘Yes. Her present from Henry. Her present when the New Year’s prince was born.’

‘It shows the king in a good light. I would not have believed him so tender. I am sure I would not have thought to do it.’
