He gazes over the ambassador’s shoulder. Look, he says, this is how it will be: in a year these damp and freezing spaces will be inhabited rooms. His hand sketches the line of the jettied upper storeys, the glazed bays.

Inventories for this project: lime and sand, oak timbers and special cements, spades and shovels, baskets and ropes, tackets, pin nails, roof nails, lead pipes; tiles yellow and tiles blue, window locks, latches, bolts and hinges, iron door handles in the shape of roses; gilding, painting, 2 lb. of frankincense to perfume the new rooms; 6d per day per labourer, and the cost of candles for labour by night.

‘My friend,’ Chapuys says, ‘Anne is desperate and dangerous. Strike first, before she strikes you. Remember how she brought down Wolsey.’

His past lies about him like a burnt house. He has been building, building, but it has taken him years to sweep up the mess.

At the Rolls House, he finds his son, who is packing to go away for the next phase of his education. ‘Gregory, you know St Uncumber? You say that women pray to her to be rid of useless husbands. Now, is there a saint that men can pray to if they wish to be quit of their wives?’

‘I don’t think so.’ Gregory is shocked. ‘The women pray because they have no other means. A man can consult a cleric to find why the marriage is not licit. Or he can chase her away and pay her money to stay in a separate house. As the Duke of Norfolk pays his wife.’

He nods. ‘That’s very helpful, Gregory.’

Anne Boleyn comes up to Whitehall to celebrate the feast of St Matthias with the king. She has changed, all in a season. She is light, starved, she looks as she did in her days of waiting, those futile years of negotiations before he, Thomas Cromwell, came along and cut the knot. Her flamboyant liveliness has faded to something austere, narrow, almost nun-like. But she does not have a nun’s composure. Her fingers play with the jewels at her girdle, tug at her sleeves, touch and retouch the jewels at her throat.

Lady Rochford says, ‘She thought that when she was queen, she would take comfort in going over the days of her coronation, hour by hour. But she says she has forgotten them. When she tries to remember, it’s as if it happened to someone else, and she wasn’t there. She didn’t tell me this, of course. She told brother George.’

From the queen’s rooms comes a dispatch: a prophetess has told her that she will not bear Henry a son while his daughter Mary is alive.

You have to admire it, he says to his nephew. She is on the offensive. She is like a serpent, you do not know when she will strike.

He has always rated Anne highly as a strategist. He has never believed in her as a passionate, spontaneous woman. Everything she does is calculated, like everything he does. He notes, as he has these many years, the careful deployment of her flashing eyes. He wonders what it would take to make her panic.
