'Who said that then?' called Father Byrne. 'What boy is talking after lights out?' And he machine-gunned the dark with his torch.

'Me,' said Roper stoutly. 'Sir,' he added. 'I only wanted to know,' he said, now illuminated. 'I don't see how an evil can be turned into a good by a ceremony. That would be like saying that the Devil can be turned into an angel again by just being blessed by a priest. I don't see it, sir.'

'Out, boy,' cried Father Byrne. 'Out of bed this instant.' His torch beckoned. 'You there at the end, turn on the lights.' Feet pattered and horrible raw yellow suddenly struck at our eyes. 'Now then,' cried Father Byrne to Roper, 'down on your knees, boy, and say a prayer for forgiveness. Who are you, worm, to doubt the omnipotence of Almighty God?'

'I wasn't doubting anything, sir,' said Roper, not yet out of bed. 'I was just interested in what you were saying, sir, even though it is a bit late.' And he thrust out a leg from the bed, as from a boat to test the temperature of the water.

'Out, boy,' shouted Father Byrne. 'Down on that floor and pray.'

'Pray for what, sir?' asked Roper, now standing, in faded blue shrunken pyjamas, between his bed and mine. 'For forgiveness because God's given me, in his infinite omnipotence, an enquiring mind?' He, like myself, was something over fifteen.

'No, boy,' said Father Byrne, with a swift Irish change to mellifluous quietness. 'Because you cast doubts on the miraculous, because you blasphemously suggest that God cannot' – crescendo – 'if He so wishes turn evil into good. Kneel, boy. Pray, boy.' (fff.)

'Why doesn't He then, sir?' asked Roper boldly, now down, though as if for an accolade, on his knees. 'Why can't we have what we all want – a universe that's really a unity?'
