Harry ignored her and spoke to his sister. ‘And you - you caused this destruction?’

She whispered, ‘You are a good man, Harry, a good brother. But you are not strong enough to do what is necessary. I prayed. God spoke to me. My mission was clear. It was worth breaking out of my cell for this, wasn’t it?’ She forced a smile, and suddenly she looked as she had when she was a little girl.

His heart broke. He stepped forward. ‘Oh, Agnes—’

But Ferron blocked his way. ‘Keep away. This witch is for the Inquisition. Keep away, I say!’ And he brought his gloved hand slamming down on the top of Harry’s head.

The world peeled away into darkness.

AD 1489

Seville was cold that February morning, and the wind that funnelled along the Guadalquivir was biting. It was a disappointment for Geoffrey, who had at least expected to be able to warm his English blood as a reward for undertaking this hellish trip.

It was a relief to get out of the open air and duck into the great cathedral, where he was supposed to meet Abdul.

In the still, incense-laden calm, he genuflected and crossed himself. The cathedral was a cavern of sandstone and marble. His gaze was drawn upwards to a vaulting roof that was filled with a golden light cast from huge stained-glass windows, a hint of heaven. There was nothing on this scale in England. The cathedral was a sink of wealth; it was expensive, tacky, uplifting, crushing; and it was certainly a monument to the untrammelled power of the Church in Spain.

Abdul Ibn Ibrahim met him just inside the doorway. His turban and long Moorish cloak looked thoroughly out of place in this Christian space.

Geoffrey greeted him. ‘I’m surprised they let you in.’

The Moor shrugged. ‘We Muslims are not barred. Perhaps the priests hope that I will be converted by the sheer stony mass of this place.’ He grinned, comfortable in himself. ‘So you arrived safely. What do you think of Spain, of Seville?’

‘Overwhelming. Like this cathedral.’

Abdul glanced around. ‘I think it’s all a bit tasteless myself. However the cathedral’s not meant for me, is it? Come,’ he said cheerfully. ‘Let me show you what is said to be the finest Moorish monument in Christian Spain.’

It turned out he meant the old mosque’s muezzin tower, called by Christians the Giralda, which still stood. There was a doorway to it from the cathedral interior, and Abdul led Geoffrey up a series of broad ramps. Geoffrey had been expecting a staircase, but Abdul said the ramps had been designed this way so that guards on horseback could climb the tower. The ascent was easy but long, and Geoffrey, not a young man, was wheezing when he reached the top.
