'That would have been expensive.'

'Edwin is rich. But they should have capped off that well.' He shook his head again. 'They should have capped it.'

I had a sudden picture of a fall into darkness, a scream echoing off dank brick walls. I shivered despite the heat of the day.

'What did the girls say happened next?'

'Avice ran for the house steward, Needler. He got a rope and climbed down. Ralph was at the bottom with his neck broken, his poor little body still warm. Needler brought him out.'

'Did the steward gave evidence at the inquest?'

'Oh, yes. David Needler was there.' Joseph frowned. I looked at him sharply.

'You don't like him?'

'He's an impertinent fellow. Used to give me sneering looks when I visited from the country.'

'So, according to their testimony, neither girl actually saw what happened?'

'No, they only looked up when they heard the shout. Elizabeth often sat out in the garden alone. Her – well, her relations with the rest of the family were – difficult. She seemed to have taken a particular dislike to Ralph.'

'I see.' I looked him in the eye. 'And what is Elizabeth like?'

He leaned back, laying the crumpled handkerchief in his lap. 'She was like Ralph in some ways. They both had the dark hair and eyes of our side of the family. She was another that liked her own way. Her poor parents indulged her, being their only one. She could be malapert, coming forward with opinions in an unmaidenly way, and she preferred book-learning to ladies' concerns. But she played the virginal well, and enjoyed embroidering. She's young, sir, young. And she has a kind nature – she was always rescuing cats and dogs from the street.'

'I see.'

'But she changed after Peter died, I have to admit that. Not surprising, her mother gone then her father and then their house sold. She withdrew into herself, sir, stopped being the eager, talkative girl I knew. I remember after Peter's funeral, when I said it would be better for her future to go to Edwin rather than back to the country with me, she gave me such a look, such anger in it, then turned away without a word.' I saw tears come to the corner of his eyes at the memory. He blinked them away.

'And things did not go well when she moved to Sir Edwin's?'

'No. After her father died I visited them several times. I was concerned for Elizabeth. Each time Edwin and my mother said she was becoming more difficult, impossible.'

'In what ways?'

'Refusing to talk to the family, keeping to her room, missing meals. Not even taking proper care of her clothes. If anyone tried to chide her she'd either say nothing or else fly into a screaming rage, calling on them all to leave her alone.'

'And she was on bad terms with all three of her cousins?'

'I think Sabine and Avice were confused by her. They told the coroner they had tried to interest her in womanly things but Elizabeth just told them to go away. She is eighteen, a little older than them, but they should have been all girls together. And Edwin's children moved in higher social circles, they could have taught Elizabeth much.' He bit his lip again. 'I had hoped for her advancement. And it has led to this.'

'And why do you think she disliked Ralph so much?'

'That I understood least of all. Edwin told me that lately, if Ralph came near Elizabeth, she would give him such looks of hate it was frightening to see. I saw it myself one evening in February. I was at dinner with the family, all of them were there. It was an uneasy meal, sir. We were eating beefsteak, my brother enjoys it very rare and I do not think Elizabeth liked it – she sat toying with her food. My mother chid her but she wouldn't reply. Then Ralph asked her, quite politely, if she was enjoying her nice red meat. She went quite pale, put down her knife and gave him such a savage look I wondered-'

'Yes.'

He whispered, 'I wondered if she were ill in her mind.'

'Elizabeth has no cause to hate the family that you know of?'

'No. Edwin is mystified, he has been mystified by her since she came to them.'

I wondered what had gone on at Sir Edwin's house, whether there were things Joseph knew but would not say, as is common enough in family matters, though he seemed frank enough. He went on, 'After they found the body, David Needler locked Elizabeth in her room and sent a message to Edwin at the Mercers' Hall. He rode home and when she wouldn't answer his questions he called the constable.' He spread his hands. 'What else could he do? He feared for the safety of his daughters and our old mother.'

'And at the inquest? Elizabeth said nothing then? Nothing at all?'

'No. The coroner told her this was her chance to speak in her defence, but she just sat looking at him with this cold, blank look. It made him angry, and the jury too.' Joseph sighed. 'The jury found Ralph had been murdered by Elizabeth Wentworth and the coroner ordered her taken to Newgate to face a murder charge at the assize. He ordered her to be kept in the Hole for her impertinence in court. And then-'

'Yes?'

'Then Elizabeth turned and looked at me. Just for a second. There was such misery in that look, sir, no anger any more, just misery.' Joseph bit his lip again. 'In the old days when she was small she was fond of me, she used to come and stay on the farm. Both my brothers saw me as a bit of a country clod, but Elizabeth loved the farm, always rushing off to see the animals as soon as she arrived.' He gave a sad smile. 'When she was little she'd try and get the sheep and pigs to play with her like her pet dog or cat and cry when they wouldn't.' He smoothed out the torn, creased handkerchief. 'She embroidered a set of these for me, you know, two years ago. What a mess I have made of it. Yet when I visit her in that awful place she is now, she just lies there, filthy, as though waiting only for death. I beg and plead with her to speak, but she stares through me as though I was not there. And she is up for trial on Saturday, in only five days' time.' His voice fell to a whisper again. 'Sometimes I fear she is possessed.'

'Come, Joseph, there is no point in thinking like that.'

He looked at me imploringly. 'Can you help her, Master Shardlake? Can you save her? You are my last hope.'

I was silent a moment, choosing my words carefully.

'The evidence against her is strong, it would be enough for a jury unless she has something to say in her defence.' I paused, then asked, 'You are sure she is not guilty?'

'Yes,' he said at once. He banged a fist on his chest. 'I feel it here. She was always kind at heart, sir, kind. She is the only one of my family I have known real kindness from. Even if she is ill in her mind, and by God's son she may be, I cannot believe she could kill a little boy.'

I took a deep breath. 'When she is brought into court she will be asked to plead guilty or not guilty. If she refuses then under the law she cannot be tried by a jury. But the alternative is worse.'

Joseph nodded. 'I know.'

'Peine forte et dure. Sharp and hard pains. She will be taken to a cell in Newgate and laid in chains on the floor. They will put a big, sharp stone under her back and a board on top of her. They will put weights on the board.'

'If only she would speak.' Joseph groaned and put his head in his hands. But I went on, I had to; he must know what she faced.

'They will allow her the barest rations of food and water. Each day more weights will be added to the board until she talks or dies of suffocation from the press of the weights. When the weights are heavy enough, because of the pressure of the stone placed underneath her back, her spine will break.' I paused. 'Some brave souls refuse to plead and allow themselves to be pressed to death because if there is no actual finding of guilt one's property is not forfeit to the State. Has Elizabeth any property?'
