I knew that in many of London’s parishes the people were increasingly grouping together into reformist and traditionalist districts. ‘Is everyone in this street of a reformist cast of mind? I know most printers are.’

‘Yes. But the sort of talk I heard that evening would be dangerous in any district. I was angry with them, for if they found themselves arrested I would be questioned too, and I have a wife and three children to think about.’ His voice trembled a little, and I realized how much the thoughtless talk of his neighbours, to say nothing of finding himself at Whitehall facing Lord Parr, had frightened him. ‘I went outside, intending to knock at the door and tell them they should have regard for their safety and mine. But as I reached the door I heard the Dutchman – he has a distinctive accent – saying a man was coming to England who was an agent of the Antichrist himself, who could bring down and destroy the realm, turn true religion to ashes. They mentioned a name, a foreign name. I’m not sure I heard it aright.’

‘What was it?’

‘It sounded like “Jurony Bertano”.’

‘That sounds Spanish, or Italian.’

‘That was all I heard. I banged on the door, called to them to speak more quietly and shut their windows, lest they find themselves in the Tower. They did not answer, but thank God they pulled the window shut and lowered their voices.’ He gave me a searching look. ‘I tell you this only because of the danger to the Queen.’

‘I am truly grateful.’

‘But there is one thing that has puzzled me all along,’ Okedene said. ‘Why would radicals have stolen Queen Catherine’s book and put her in danger?’

‘That is something I wonder about, too.’

‘Certainly I never overheard any mention of the Queen’s name. But as I say, apart from that particular night when I heard that name Jurony Bertano, it was mostly just the occasional phrase I heard.’ He sighed. ‘But nowhere is safe in these days.’

Footsteps sounded outside. Someone had come up the stairs, quietly, and we had not heard. Okedene and I looked at each other in alarm. The door opened. Nicholas came in, looking pleased with himself. ‘Could you not knock?’ I said angrily. ‘Master Okedene, this is my pupil, Nicholas Overton. I apologize for his manners.’

Nicholas looked hurt. He bowed to Okedene, then turned quickly back to me. ‘I am sorry, sir, but I found something in the garden.’

I wished he had not blurted that out in front of Okedene. It was best for his safety that he knew as little as possible. But Nicholas went on. ‘I climbed over the wall. The garden on the other side is very overgrown, with high grass and brambles. There was only a family of beggars there, taking shelter in the ruins of what looks like an abandoned monastic building.’
