There is an unholy roar. It is something between a moan and a cheer and a wail of panic, a shout to God, a riposte to the devil.

Beneath the jacket, within the horsehair padding, a fibrillation, a quiver of life: his hand heavy and flat on the regal breast, he feels he is raising Lazarus. It is as if his palm, magnetised, is drawing life back into his prince. The king’s respiration, though shallow, seems steady. He, Cromwell, has seen the future; he has seen England without Henry; he prays aloud, ‘Long live the king.’

‘Fetch the surgeons,’ he says. ‘Fetch Butts. Fetch any man with skill. If he dies again, they will not be blamed. My word on that. Get me Richard Cromwell my nephew. Fetch a stool for my lord Norfolk, he has had a shock.’ He is tempted to add, throw a bucket of water on Gentle Norris: whose prayers, he has time to notice, are of a marked papist character.

The tent is now so crowded that it seems to have been picked up by its moorings, to be carried on men’s heads. He takes a last look at Henry before his still form disappears under the ministrations of doctors and priests. He hears a long, retching gasp; but one has heard the same from corpses.

‘Breathe,’ Norfolk shouts. ‘Let the king breathe!’ And as if in obedience, the fallen man takes a deep, sucking, scraping breath. And then he swears. And then he tries to sit up.

And it is over.

But not entirely: not until he has studied the Boleyn expressions around. They look numb, bemused. Their faces are pinched in the bitter cold. Their great hour has passed, before they realised it has arrived. How have they all got here so fast? Where have they come from? he asks Fitz. Only then he realises that the light is fading. What felt like ten minutes has been two hours: two hours since Rafe stood in the doorway, and he dropped his pen on the page.

He says to Fitzwilliam, ‘Of course, it never happened. Or if it did, it was an incident of no importance.’

For Chapuys and the other ambassadors, he will stick by his original version: the king fell, hit his head, and was unconscious for ten minutes. No, at no time did we think he was dead. After ten minutes he sat up. And now he is perfectly well.

The way I tell it, he says to Fitzwilliam, you would think that the blow on the head had improved him. That he actually set out to get it. That every monarch needs a blow on the head, from time to time.

Fitzwilliam is amused. ‘A man’s thoughts at such a time hardly bear scrutiny. I recall thinking, should we not send for the Lord Chancellor? But I don’t know what I thought he was to do.’

‘My thought,’ he confesses, ‘was, somebody get the Archbishop of Canterbury. I think I believed a king couldn’t die without his supervision. Imagine trying to bustle Cranmer across the Thames. He would make you join him in a gospel reading first.’
