The brothers let go of the girl’s arms. She slumped to her hands and knees, and Geoffrey saw her back for the first time. Bloody stripes were clearly visible through the thin cloth of her shift.

Geoffrey found himself on his feet. ‘This is an outrage. She has been whipped!’

Ferron turned that stern glare on him. ‘All due and lawful process has been followed. The girl was given thirty days’ grace in which to make her full and voluntary confession. When the thirty days expired, she was encouraged further to speak.’

‘You call this encouragement?’

‘And when she still failed to speak, she has been brought before the court. Perhaps she will speak here. But you, friar, will keep your silence, or you will be ejected.’

Geoffrey sat, fuming.

Ferron fixed the girl with his cold judgemental stare. ‘Agnes Wooler. You are guilty of wanton destruction. You have damaged an ancient project with holy and pious purposes: you have blunted the swords of our new crusade. And, further, you took many lives in the process.’

Geoffrey put in, ‘No. No lives were lost. She gave the friars in that manufactory sufficient warning. Whatever you think of her actions against the engines, she’s not guilty of murder.’

Ferron ignored him again. ‘Further I put it to you, Agnes Wooler, that you have been complicit in the corruption of a supplicant at the court of Fernando and Isabel, whom God has chosen as His emissaries on earth in this dark time. I mean Cristobal Colon, the navigator.’ And Ferron spoke evenly about the ‘Chinese’ body discovered on the shore at Palos. Colon had believed this to be a relic washed east from Asia. But the body had been examined by a physician, who argued from blood-pooling that its tattoos had been applied after death. Its strange eye-folds were artificial too, the result of a bit of surgery, again performed after death. ‘The body was a fake, designed to baffle Cristobal Colon and to thwart the holy purpose of the monarchs.’

Ferron produced other bits of evidence, selected bits of scholarship fed to Colon. ‘There’s really quite a conspiracy, it seems, to pour this nonsense of westward voyages into Colon’s head. And it can’t be a coincidence that your destruction of God’s engines happened to occur on the very day that Colon’s brother Bartolomeo was there to see it.’

Geoffrey was depressed at how much Ferron knew. Piously cruel he might be, but Ferron was evidently no fool. He tried to protest. ‘What on earth can this wretched English girl have to do with the goings-on at the royal court of Spain? She’s spent most of her adult life in York, locked up in the cell of an anchoress!’
