'What is it?'

He handed me a paper. 'Judge Forbizer has reconsidered, sir. He asked me to give you this.'

'What?'

'He has reconsidered. You are to have another two weeks to persuade Mistress Wentworth to plead.'

I stared at him uncomprehendingly. No one could have looked less like reconsidering than Forbizer. There was something shifty, uneasy, in the clerk's face. 'A copy of this has gone to Newgate already.' He thrust the paper at me and vanished back into the courtroom.

I looked at it. A brief order above Forbizer's spiky signature, stating Elizabeth Wentworth was to be detained in the Newgate Hole for another twelve days, until the tenth of June, to reconsider her plea. I sat staring around the hall, trying to work it out. It was an extraordinary thing for any judge to do, let alone Forbizer.

There was a touch on my arm. I looked up to find the sharp-faced young man at my elbow. I frowned and he smiled again, a cynical smile that turned up one corner of his mouth, showing white even teeth.

'Master Shardlake,' he said, 'I see you have the order.' His voice was as sharp as his face, with the burr of a London commoner.

'What do you mean? Who are you?'

He gave a small bow. 'Jack Barak, sir, at your service. It was I persuaded Judge Forbizer to grant the order just now. You did not see me slip behind the bench?'

'No. But – what is this?'

His smile vanished and again I saw the hardness in his face. 'I serve Lord Cromwell. It was in his name I persuaded the judge to give you more time. He didn't want to, stiff-necked old arsehole, but my master is not refused. You know that.'

'Cromwell? Why?'

'He would see you, sir. He is nearby, at the Rolls House. He asks me to take you there.'

My heart began pounding with apprehension. 'Why? What does he want? I haven't seen him in close on three years.'

'He has a commission for you, sir.' Barak raised his eyebrows and stared at me insolently with those large brown eyes. 'Two weeks' more life for the girl is your fee, paid in advance.'

BARAK LED ME at a brisk pace to the courthouse stables. My heart still banged against my ribs and the skin on my face had a tight, drawn feeling. I knew Lord Cromwell was not above bullying judges, but he always liked to observe the legal niceties and would not have done this lightly. And Barak was a strange person to use to confront a judge. But though he had risen to be chief minister, Cromwell was the son of a Putney alehouse keeper and was happy to work with men of low birth so long as they were intelligent and ruthless enough. But what in Christ's name did Cromwell want from me? His last mission had plunged me into a hell of murder and violence I still shuddered to recall.

Barak's horse was a beautiful black mare, its coat shining with health. He cantered out while I was still saddling Chancery, pausing in the stable doorway to look back impatiently. 'Ready?' he asked. 'His lordship wants to see you this morning, you know.'

I studied him again as I climbed on the vaulting block and eased myself onto Chancery's back. A hard eye and a fighter's build, as I had observed before. A heavy sword at his hip and a dagger too at his belt. But there was intelligence in his eyes and in the wide, sensual mouth, whose upturned corners seemed made for mockery.

'Wait a moment,' I said, seeing Joseph running across the yard to us, his plump face bright, clutching his cap in his hand. When he had returned from the jakes I told him Forbizer had changed his mind: I said I did not know why. 'Your advocacy, sir,' he had said. 'Your words moved his conscience.' Joseph was ever a naive man.

Now he laid a hand on Chancery's side, beaming up at me. 'I have to go with this gentleman, Joseph,' I said. 'There is another urgent case I must attend to.'

'Some other poor wretch to save from injustice, eh? But you will be back soon?'

I glanced at Barak; he gave a brief nod.

'Soon, Joseph. I will contact you. Listen, now we have some time to investigate Ralph's murder there is something I would have you do for me, if you can. It will be difficult-'

'Anything, sir, anything.'

'I want you to go to your brother Edwin and ask if he will see me at his house. Say I am unsure of Elizabeth's guilt and wish to hear his side of things.'

A shadow came over his face. 'I need to meet the family, Joseph,' I told him gently. 'And see the house and garden. It is important.'

He bit his lip, then nodded slowly. 'I will do what I can.'

I patted his arm. 'Good man. And now I must go.'

'I shall tell Elizabeth!' he called after me as we rode out into the road. 'I shall tell her, thanks to you, she is spared the press!' Barak looked at me, raising an eyebrow cynically.

WE RODE DOWN Old Bailey Street. The Rolls House was not far, directly opposite Lincoln's Inn in fact. A sprawling complex of buildings, it had once been the Domus Conversorum, where Jews who wished to convert to Christianity were instructed. Since the expulsion of all Jews from England centuries before, the building had been used to house the Court of Chancery Rolls, though one or two foreign Jews, who had washed up in England somehow and agreed to convert to Christianity, were still housed there from time to time. The Six Clerks' Office, which administered the Court of Chancery, was located there too. The office of Keeper of the Domus was still combined with the Mastership of the Rolls.

'I thought Lord Cromwell had given up the mastership,' I said to Barak.

'He still keeps an office in the Rolls House. Works there sometimes when he wants to be undisturbed.'

'Can you tell me what this is about?'

He shook his head. 'My master is to tell you himself.'

We rode up Ludgate Hill. It was another hot day; the women bringing produce into town were wearing cloths over their faces to protect them from the dust thrown up by passing carts. I looked down over the red-tiled rooftops of London, and the broad shining band of the river. The tide was out and the Thames mud, stained yellow and green with the refuse that poured every day from the northern shore, lay exposed like a great stain. People said that recently will o'the wisps of flame had been seen at night dancing over the rubbish and wondered uneasily what it portended.

I made another attempt to get information. 'This must be important to your master. Forbizer's not intimidated lightly.'

'He's a care for his skin like all men of the law.' There was an edge of contempt in Barak's voice.

'This sore puzzles me.' I paused, then added, 'Am I in trouble?'

He turned. 'No, not if you do as you're told. It's as I said, my master has a commission for you. Now come: time is important.'

We entered Fleet Street. The dust hung over the Whitefriars' monastic buildings in a pall, for the great friary was in the course of demolition. The gatehouse was covered in scaffolding, men hacking away at the decoration with chisels. A workman stepped into our path, raising a dusty hand.

'Halt your horses, please, sirs,' he called out.

Barak frowned. 'We're on Lord Cromwell's business. Piss off.'

The man wiped his hand on his grubby smock. 'I'm sorry, sir. I only wished to warn you, they're about to blow up the Whiteys' chapter house, the noise could startle the horses-'

'Look-' Barak broke off suddenly. A flash of red light appeared over the wall, followed by a tremendous explosion, louder than a clap of thunder. A heavy crash of falling stone, accompanied by cheers, sounded as a surging cloud of dust rolled over us. Hot-blooded as it looked, Barak's mare only neighed and jerked aside, but Chancery let out a scream and reared up on his hind legs, nearly unseating me. Barak reached across and grabbed the reins.
