The king's maternal grandfather, as all old men will tell you, stood six foot four. (His father, however, was more the size of Morgan Williams.) The king stands six foot two, and the cardinal can look him in the eye. Henry likes to have about him men like his brother-in-law Charles Brandon, of a similar impressive height and breadth of padded shoulder. Height is not the fashion in the back alleys; and, obviously, not in Yorkshire.

He smiles. What he says about Gregory is, at least he isn't like I was, when I was his age; and when people say, what were you like? he says, oh, I used to stick knives in people. Gregory would never do that; so he doesn't mind – or minds less than people think – if he doesn't really get to grips with declensions and conjugations. When people tell him what Gregory has failed to do, he says, ‘He's busy growing.’ He understands his need to sleep; he never got much sleep himself, with Walter stamping around, and after he ran away he was always on the ship or on the road, and then he found himself in an army. The thing people don't understand about an army is its great, unpunctuated wastes of inaction: you have to scavenge for food, you are camped out somewhere with a rising water level because your mad capitaine says so, you are shifted abruptly in the middle of the night into some indefensible position, so you never really sleep, your equipment is defective, the gunners keep causing small unwanted explosions, the crossbow-men are either drunk or praying, the arrows are ordered up but not here yet, and your whole mind is occupied by a seething anxiety that things are going to go badly because il principe, or whatever little worshipfulness is in charge today, is not very good at the basic business of thinking. It didn't take him many winters to get out of fighting and into supply. In Italy, you could always fight in the summer, if you felt like it. If you wanted to go out.

‘Asleep?’ Liz says.

‘No. But dreaming.’

‘The Castile soap came. And your book from Germany. It was packaged as something else. I almost sent the boy away.’

In Yorkshire, which smelled of unwashed men, wearing sheepskins and sweating with anger, he had dreams about the Castile soap.

Later she says, ‘So who is the lady?’

His hand, resting on her familiar but lovely left breast, removes itself in bewilderment. ‘What?’ Does she think he has taken up with some woman in Yorkshire? He falls on to his back and wonders how to persuade her this is not so; if necessary he'll take her there, and then she'll see.

‘The emerald lady?’ she says. ‘I only ask because people say the king is wanting to do something very strange, and I can't really believe it. But that is the word in the city.’

Really? Rumour has advanced, in the fortnight while he has been north among the slope-heads.

‘If he tries this,’ she says, ‘then half the people in the world will be against it.’

He had only thought, and Wolsey had only thought, that the Emperor and Spain would be against it. Only the Emperor. He smiles in the dark, hands behind his head. He doesn't say, which people, but waits for Liz to tell him. ‘All women,’ she says. ‘All women everywhere in England. All women who have a daughter but no son. All women who have lost a child. All women who have lost any hope of having a child. All women who are forty.’

She puts her head on his shoulder. Too tired to speak, they lie side by side, in sheets of fine linen, under a quilt of yellow turkey satin. Their bodies breathe out the faint borrowed scent of sun and herbs. In Castilian, he remembers, he can insult people.

‘Are you asleep now?’

‘No. Thinking.’

‘Thomas,’ she says, sounding shocked, ‘it's three o'clock.’

And then it is six. He dreams that all the women of England are in bed, jostling and pushing him out of it. So he gets up, to read his German book, before Liz can do anything about it.

It's not that she says anything; or only, when provoked, she says, ‘My prayer book is good reading for me.’ And indeed she does read her prayer book, taking it in her hand absently in the middle of the day – but only half stopping what she's doing – interspersing her murmured litany with household instructions; it was a wedding present, a book of hours, from her first husband, and he wrote her new married name in it, Elizabeth Williams. Sometimes, feeling jealous, he would like to write other things, contrarian sentiments: he knew Liz's first husband, but that doesn't mean he liked him. He has said, Liz, there's Tyndale's book, his New Testament, in the locked chest there, read it, here's the key; she says, you read it to me if you're so keen, and he says, it's in English, read it for yourself: that's the point, Lizzie. You read it, you'll be surprised what's not in it.

He'd thought this hint would draw her: seemingly not. He can't imagine himself reading to his household; he's not, like Thomas More, some sort of failed priest, a frustrated preacher. He never sees More – a star in another firmament, who acknowledges him with a grim nod – without wanting to ask him, what's wrong with you? Or what's wrong with me? Why does everything you know, and everything you've learned, confirm you in what you believed before? Whereas in my case, what I grew up with, and what I thought I believed, is chipped away a little and a little, a fragment then a piece and then a piece more. With every month that passes, the corners are knocked off the certainties of this world: and the next world too. Show me where it says, in the Bible, ‘Purgatory’. Show me where it says relics, monks, nuns. Show me where it says ‘Pope’.

He turns back to his German book. The king, with help from Thomas More, has written a book against Luther, for which the Pope has granted him the title of Defender of the Faith. It's not that he loves Brother Martin himself; he and the cardinal agree it would be better if Luther had never been born, or better if he had been born more subtle. Still, he keeps up with what's written, with what's smuggled through the Channel ports, and the little East Anglian inlets, the tidal creeks where a small boat with dubious cargo can be beached and pushed out again, by moonlight, to sea. He keeps the cardinal informed, so that when More and his clerical friends storm in, breathing hellfire about the newest heresy, the cardinal can make calming gestures, and say, ‘Gentlemen, I am already informed.’ Wolsey will burn books, but not men. He did so, only last October, at St Paul's Cross: a holocaust of the English language, and so much rag-rich paper consumed, and so much black printers' ink.

The Testament he keeps in the chest is the pirated edition from Antwerp, which is easier to get hold of than the proper German printing. He knows William Tyndale; before London got too hot for him, he lodged six months with Humphrey Monmouth, the master draper, in the city. He is a principled man, a hard man, and Thomas More calls him The Beast; he looks as if he has never laughed in his life, but then, what's there to laugh about, when you're driven from your native shore? His Testament is in octavo, nasty cheap paper: on the title page, where the printer's colophon and address should be, the words ‘PRINTED IN UTOPIA’. He hopes Thomas More has seen one of these. He is tempted to show him, just to see his face.

He closes the new book. It's time to get on with the day. He knows he has not time to put the text into Latin himself, so it can be discreetly circulated; he should ask somebody to do it for him, for love or money. It is surprising how much love there is, these days, between those who read German.

By seven, he is shaved, breakfasted and wrapped beautifully in fresh unborrowed linen and dark fine wool. Sometimes, at this hour, he misses Liz's father; that good old man, who would always be up early, ready to drop a flat hand on his head and say, enjoy your day, Thomas, on my behalf.

He had liked old Wykys. He first came to him on a legal matter. In those days he was – what, twenty-six, twenty-seven? – not long back from abroad, prone to start a sentence in one language and finish it in another. Wykys had been shrewd and had made a tidy fortune in the wool trade. He was a Putney man originally, but that wasn't why he employed him; it was because he came recommended and came cheap. At their first conference, as Wykys laid out the papers, he had said, ‘You're Walter's lad, aren't you? So what happened? Because, by God, there was no one rougher than you were when you were a boy.’

He would have explained, if he'd known what sort of explanation Wykys would understand. I gave up fighting because, when I lived in Florence, I looked at frescoes every day? He said, ‘I found an easier way to be.’

Latterly, Wykys had grown tired, let the business slide. He was still sending broadcloth to the north German market, when – in his opinion, with wool so long in the fleece these days, and good broadcloth hard to weave – he ought to be getting into kerseys, lighter cloth like that, exporting through Antwerp to Italy. But he listened – he was a good listener – to the old man's gripes, and said, ‘Things are changing. Let me take you to the cloth fairs this year.’
