'I shall.' He led me to the door. I turned back to him. 'Don't forget that prayer.'

'I won't.'

I unhitched Chancery and rode up the lane. As I passed the Old Barge I looked up at the window where I had seen the figure. It was still shuttered. But as I turned back into Bucklersbury I had the feeling of being watched again. I turned my head abruptly. The streets were getting busy, but I saw a man in a doublet of lusty-gallant red leaning against a wall with his arms folded, staring straight at me. He was in his late twenties, with a strong-featured face, comely but hard, under untidy brown hair. He had a fighter's build, broad shoulders and a narrow waist. As he met my gaze his wide mouth twisted into a mocking grin. Then he turned away and walked with a quick, light step towards the Barge, disappearing into the crowds.

AS I RODE BACK TO Newgate I reflected anxiously on my watcher. Could the man have some connection with the Wentworth case? I had mentioned the case at Lincoln's Inn the afternoon before and gossip travels faster among lawyers than among the washerwomen in Moorgate fields. Or was he some agent of the State, investigating my dealings with the dark-skinned ex-monk? Yet these days I had no connections with politics.

Chancery stirred uneasily and neighed, sensing my worry or perhaps made uneasy by the dreadful smells that assailed us as we passed the Shambles, a foul trail of blood and fluids seeping down the channel from Bladder Street. The stink here was always bad, however much the City might try to regulate the butchers, but on a hot day like this it was unbearable. If this weather went on I should have to buy a nosegay, I thought, noticing that many of the richer-looking passers-by held posies of spring flowers before their faces.

I passed into Newgate Market, still overshadowed by the great monastic church of Greyfriars, behind whose stained-glass windows the king now stored booty taken from the French at sea. Beyond stood the high City wall and, built into it, the chequered towers of Newgate. London's principal gaol is a fine, ancient building, yet it holds more misery than anywhere in London, many of its inhabitants leaving it only for their execution.

I entered the Pope's Head tavern. It was open all hours and did a good trade from visitors to the gaol. Joseph sat at a table overlooking the dusty rear garden, nursing a cup of small beer, the weak beer drunk to quench thirst. A posy of flowers lay beside him. He was looking uneasily at a well-dressed young man who was leaning over him, smiling affably.

'Come, Brother, a game of cards will cheer you up. I am due to meet some friends at an inn nearby. Good company.' He was one of the coneycatchers who infest the City, looking for country people in their dull clothes who were new to town to fleece them of their money.

'Excuse us,' I said sharply, easing myself into a chair. 'This gentleman and I are due to have conference. I am his lawyer.'

The young man raised his eyebrows at Joseph. 'Then you'll lose all your money anyway, sir,' he said. 'Justice is a fat fee.' As he passed me he leaned close. 'Crook-backed bloodsucker,' he murmured softly.

Joseph did not hear. 'I've been to the gaol again,' he said gloomily. 'I told the gaoler I was bringing a lawyer. Another sixpence he charged, to allow the visit. What's more he had a copy of that filthy pamphlet. He told me he's been letting people in to look at Elizabeth for a penny. They call out through the spyhole and insult her. He laughed about it. It's cruel – surely they're not allowed to do that?'

'The gaolers are allowed anything for their own profit. He would have told you in hope of a bribe to keep her free of such pestering.'

He ran a hand through his hair. 'I have had to pay for food for her, water, everything. I can't afford more, sir.' He shook his head. 'These gaolers must be the wickedest men on earth.'

'Ay. But clever enough at turning a profit.' I looked at him seriously. 'I went to Lincoln's Inn yesterday afternoon, Joseph. I learned the judge sitting at Saturday's assize is Forbizer. That is no good news. He's a strong Bible man and incorruptible-'

'But that's good, surely, a Bible man-'

I shook my head. 'Incorruptible, but hard as stone.'

'No sympathy for a young orphan girl half out of her wits?'

'Not for any living creature. I've appeared before him in civil matters.' I leaned forward. 'Joseph, we must get Elizabeth to talk or she's as good as dead.'

He bit his lip in that characteristic gesture of his. 'When I took her some food yesterday she just lay there and looked at it. Not a word of thanks, not even a nod. I think she's hardly eaten for days. I've bought her these flowers but I don't know if she'll look at them.'

'Well, let us see what I can do.'

He nodded gratefully. As we got up I said, 'By the way, does Sir Edwin know you have retained me?'

Joseph shook his head. 'I haven't spoken with Edwin in a week, since I suggested that Elizabeth might not be guilty and he ordered me from his house.' A flash of anger crossed his face. 'He thinks that if I do not want Elizabeth to die, I must be against him and his.'

'Nonetheless,' I said thoughtfully, 'he might have heard.'

'What makes you think so, sir?'

'Oh, nothing. Never mind.'

JOSEPH'S WHOLE BODY seemed to slump as we approached the gaol. We passed the begging grille in the wall through which poor prisoners thrust clutching hands, calling to passers-by for charity for God's love. Those without money got little or no food and it was said some prisoners starved to death. I placed a penny in a grubby, frantic hand, then knocked loudly at the stout wooden door. A spy flap opened and a hard face looked out from under a greasy cap, eyes flicking over my black lawyer's robe.

'Lawyer for Elizabeth Wentworth,' I said, 'with her uncle. He's paid for the visit.' The flap slammed shut and the door opened. The gaoler, dressed in a dirty smock and with a heavy stick at his belt, looked at me curiously as we passed through. Despite the heat of the day the prison with its thick stone walls was cold, a dank chill seeming to emanate from the very stones. The gaoler called out, 'Wilhams!' and a fat turnkey in a leather jerkin appeared, jangling a large ring of keys in one hand.

'Lawyer for the child murderess.' The gaoler smiled evilly at me. 'Seen the pamphlet?'

'Yes,' I answered shortly.

He shook his head. 'She still won't talk; it'll be the press for her. Did you know, lawyer, there's an old rule prisoners should be naked when they're laid out chained for the weights to be put on 'em. Shame to get a view of a nice pair of bubbies, then have to squash 'em flat.'

Joseph's face puckered with distress.

'There is no such rule that I know of,' I said coldly.

The gaoler spat on the floor. 'I know the rules for my own gaol, whatever pen gents may say.' He nodded to the turnkey. 'Take 'em down to the Women's Hole.'

We were led down a wide corridor with wards on either side. Through the barred windows in the doors men were visible sitting or lying on straw pallets, their legs fixed to the walls by long chains. The smell of urine was so strong it stung the nostrils. The turnkey waddled along, keys rattling. Unlocking a heavy door, he led us down a flight of steps into semi-darkness. At the bottom another door faced us. The turnkey pulled aside a flap and peered in before turning to us.

'Still lying just where she was yesterday afternoon when I brought those people down to look at her through the hatch. Silent as a stone she was, hiding herself while they called witch and child killer through the door.' He shook his head.
