‘I am here about the murder last week of Armistead Greening, God pardon his soul. I understand the coroner has put you in charge of the investigation.’

Fletcher sighed. ‘He has.’

‘I am Serjeant Matthew Shardlake, of Lincoln’s Inn. My pupil, Master Overton. Master Greening’s parents are sore grieved at his loss, and have asked me to assist in the investigations, with your permission. I have a power of attorney.’ I passed the document to him.

‘Please sit, sirs.’ Fletcher removed papers from a couple of stools and laid them on the floor. When we were seated he regarded me seriously. ‘You will know, sir, that if a murderer is not caught within the first two days, and his identity is unknown, the chances of finding him are small.’

‘I know it well. I have been involved in such investigations before, and understand how difficult they are.’ I glanced at the papers piled around. ‘And I know how heavy the duties are for the city constables in these days.’ I smiled sympathetically. ‘Investigating a brutal murder must be yet one more burden.’

Fletcher nodded sadly. ‘It is indeed.’ He hesitated, then said, ‘If you would take on the investigation I should be grateful.’

I nodded. I had read the man aright; many London constables were lazy and venal but Fletcher was conscientious and hopelessly overburdened. And affected, perhaps, by what he had had to do yesterday. The burning.

‘I would keep you informed of any developments, of course,’ I said. ‘And you would be the one to report any discoveries to the coroner.’ And take the credit, I implied.

He nodded.

‘Perhaps I could begin by asking you what you know of the circumstances of the murder. My pupil will take notes, if you will permit.’ Nicholas took quill and paper from his satchel. Fletcher gestured to him to help himself from his inkwell, then folded his arms and sat back.

‘I was visited somewhat after nine on the evening of the tenth, just as the light was fading, by one of my watchmen. He told me that a printer of Paternoster Row, Armistead Greening, had been murdered, and also reported the hue and cry raised by his neighbour, Master Okedene, who discovered the body. I sent a message to the coroner and went across to Paternoster Row. Okedene was there, looking in a bad state. He said he had been working late in his print-shop with his assistant, using the last of the light, when he heard a loud cry for help from Greening’s works next door, then bangs and shouts. Master Okedene is a man of some substance, but Greening was in a small way of business, his workshop little more than a wooden hut.’

‘Not a very secure place, then?’
