Rice brings in with him a little velvet box, which he puts down on the desk: ‘Present. You have to guess.’

He rattles it. Something like grains. His finger explores fragments, scaly, grey. Rice has been surveying abbeys for him. ‘It wouldn’t be St Apollonia’s teeth?’

‘Guess again.’

‘Is it teeth from the comb of Mary Magdalene?’

Rice relents. ‘St Edmund’s nail parings.’

‘Ah. Tip them in with the rest. The man must have had five hundred fingers.’

In the year 1257, an elephant died in the Tower menagerie and was buried in a pit near the chapel. But the following year he was dug up and his remains sent to Westminster Abbey. Now, what did they want at Westminster Abbey, with the remains of an elephant? If not to carve a ton of relics out of him, and make his animal bones into the bones of saints?

According to the custodians of holy relics, part of the power of these artefacts is that they are able to multiply. Bone, wood and stone have, like animals, the ability to breed, yet keep their intact nature; the offspring are in no wise inferior to the originals. So the crown of thorns blossoms. The cross of Christ puts out buds; it flourishes, like a living tree. Christ’s seamless coat weaves copies of itself. Nails give birth to nails.

John ap Rice says, ‘Reason cannot win against these people. You try to open their eyes. But ranged against you are statues of the virgin that weep tears of blood.’

‘And they say I play tricks!’ He broods. ‘John, you must sit down and write. Your compatriots must have prayers.’

‘They must have a Bible, sir, in their own tongue.’

‘Let me first get the king’s assured blessing for the English to have it.’ It is his daily, covert crusade: for Henry to sponsor a great Bible, put it in every church. He is very close now and he thinks he can win Henry to it. His ideal would be a single country, single coinage, just one method of weighing and measuring, and above all one language that everybody owns. You don’t have to go to Wales to be misunderstood. There are parts of this realm not fifty miles from London, where if you ask them to cook you a herring they give you a blank look instead. Only when you’ve pointed to the pan and impersonated a fish do they say, ah, now I see what you mean.

But his greatest ambition for England is this: the prince and his commonwealth should be in accord. He doesn’t want the kingdom to be run like Walter’s house in Putney, with fighting all the time and the sound of banging and shrieking day and night. He wants it to be a household where everybody knows what they have to do, and feels safe doing it. He says to Rice, ‘Stephen Gardiner says I should write a book. What do you think? Perhaps I might if one day I retire. Till then, why should I give my secrets away?’
