I said nothing. I know that he expected me to be shocked. I was, at everything he’d said, but reading the Spook’s diary back in Chipenden had prepared me for the worst.

Father Cairns gave another deep sniff then coughed deep in his throat. ‘Do you know which of his six brothers John Gregory wronged?’

I’d already guessed. ‘Father Gregory,’ I answered.

‘In devout families such as the Gregorys, it is the tradition that one son takes Holy Orders. When John threw away his vocation, another brother took his place and began training for the priesthood. Yes, Thomas, it was Father Gregory, the brother we buried today. He lost his betrothed and he lost his brother. What else could he do but turn to God?’

When I’d arrived, the church had been almost empty, but as we’d talked I’d become aware of sounds outside the confessional box. There’d been footsteps and the increasing murmur of voices. Now, suddenly, a choir began to sing. It would be well after seven by now and the sun would already have set. I decided to make an excuse and leave but just as I opened my mouth I heard Father Cairns come to his feet.

‘Come with me, Thomas,’ he said. ‘I want to show you something.’

I heard him open his door and go out into the church, so I followed.

He beckoned me towards the altar where, led by another priest, neatly arranged in three rows of ten, a choir of altar boys was standing on the steps. Each wore a black cassock and white surplice.

Father Cairns halted and put his bandaged hand on my right shoulder.

‘Listen to them, Thomas. Don’t they sound like holy angels?’

I’d never heard an angel sing so I couldn’t answer, but they certainly made a better noise than my dad, who used to start singing as we got near to the end of the milking. His voice was bad enough to turn the milk sour.

‘You could have been a member of that choir, Thomas. But you’ve left it too late. Your voice is already beginning to deepen and a chance to serve has been lost.’

He was right about that. Most of the boys were younger than me and their voices were more like girls’ than lads’. In any case, my singing wasn’t much better than my dad’s.

‘Still, there are other things you can do. Let me show you…’

He led the way past the altar, through a door and along a corridor. Then we went out into the garden at the rear of the cathedral. Well, it was more the size of a field than a garden, and rather than flowers and roses, vegetables grew there.

It was already beginning to get dark but there was still enough light to see a hawthorn hedge in the distance with the gravestones of the churchyard just visible beyond it. In the foreground a priest was on his knees, weeding with a trowel. It was a big garden and only a small trowel.

‘You come from a family of farmers, Thomas. It’s good, honest work. You’d be at home working here,’ he said, pointing to the kneeling priest.

I shook my head. ‘I don’t want to be a priest,’ I said firmly.

‘Oh, you could never be a priest!’ Father Cairns said, his voice filled with shock and indignation. ‘You’ve been too close to the Devil for that and now will have to be watched closely for the rest of your life lest you slip back. No, that man is a brother.’

‘A brother?’ I asked, puzzled, thinking he was family or something.

The priest smiled. ‘At a big cathedral like this, priests have assistants who offer support. We call them brothers because, although they can’t administer the sacraments, they do other vital tasks and are part of the family of the Church. Brother Peter is our gardener and very good at it too. What do you say, Thomas? Would you like to be a brother?’

I knew all about being a brother. With being the youngest of seven, I’d been given all the jobs that nobody else wanted to do. It looked like it was the same here. In any case, I already had a job and I didn’t believe what Father Cairns had told me about the Devil and the Spook. It had made me think a bit, but deep down I knew it couldn’t be true. Mr Gregory was a good man.

It was getting darker and chillier by the moment so I decided it was time to go.

‘Thanks for talking to me, Father,’ I said, ‘But could you tell me about the danger to Mr Gregory now, please?’

‘All in good time, Thomas,’ he said, giving me a little smile.

Something in that smile told me that I’d been tricked. That he had no intention at all of helping the Spook.

‘I’ll think about what you’ve told me but I’ve got to be getting back now or I’ll miss my supper,’ I told him. It seemed a good excuse at the time. He’d no way of knowing that I was fasting because I had to be ready to deal with the Bane.

‘We’ve got supper for you here, Thomas,’ said Father Cairns. ‘In fact we’d like you to stay the night.’

Two other priests had come out of the side door and were walking towards us. They were big men and I didn’t like the expressions on their faces.

There was a moment when I could probably have got away, but it seemed silly to run when I wasn’t really sure what was going to happen.

Then it was too late because the priests stood on each side of me, gripping me firmly by my upper arms and shoulders. I didn’t struggle because there was no point. Their hands were big and heavy and I felt that if I stayed in the same spot too long, I’d start to sink into the earth. Then they walked me back into the vestry.

‘This is for your own good, Thomas,’ Father Cairns said, as he followed us inside. ‘The Quisitor will seize John Gregory tonight. He’ll have a trial, of course, but the outcome is certain. Found guilty of dealing with the Devil, he will be burned at the stake. That’s why I can’t let you go back to him. There’s still a chance for you. You’re just a boy and your soul can still be saved without burning. But if you’re with him when he’s arrested then you’ll suffer the same fate. So this is for your own good.’

‘But he’s your cousin!’ I blurted out. ‘He’s family. How can you do this? Let me go and warn him.’

‘Warn him?’ asked Father Cairns. ‘Do you think I haven’t tried to warn him? I’ve been warning him for most of his adult life. Now I need to think about his soul more than his body. The flames will cleanse him. By means of pain, his soul can be saved. Don’t you see? I’m doing it to help him, Thomas. There are much more important things than our brief existence in this world.’

‘You’ve betrayed him! Your own flesh and blood. You’ve told the Quisitor we’re here!’

‘Not both of you, just John. So join us, Thomas. Your soul will be cleansed through prayer and your life will no longer be in danger. What do you say?’

There was no point in arguing with someone who was so sure that he was right, so I didn’t waste my breath. The only sound to be heard was the echo of our footsteps and the jangle of keys as they led me further and further into the gloom of the cathedral.
