The front door was open, and I saw to my surprise that a woman in a plain servant's dress was hanging onto the jamb with both hands, as though afraid of falling.

'What's this?' Barak asked. 'Drunk at one in the afternoon?'

'I don't think it's that.' I had a sudden feeling of dread. Then, seeing us, the woman let out a screeching wail.

'Help! For Jesu's sake, help me! Murder!'

Barak jumped down and ran towards her. I threw the horses' reins quickly over a rail, and ran over. Barak had the woman by the arms; she was staring wildly at him, sobbing loudly.

'Come on, girl,' he said with surprising gentleness. 'What ails you?'

She made an effort to calm herself. She was young and plump-cheeked, a country girl by the look of her.

'The master,' she said. 'Oh, God, the master-'

I saw that the wood of the doorframe was splintered and broken. The door, which hung from one hinge, had been battered in. I looked past her and down a long dim corridor hung with a faded tapestry showing the three kings bearing gifts to the infant Jesus. Then I gripped Barak's arm. The rushes on the wooden floor were criss-crossed with footprints. They were dark red.

'What has happened here?' I whispered.

Barak shook the girl gently. 'We're here to help. Come on now, what's your name?'

Whoever smashed their way in could still be here. I gripped the dagger at my waist.

'I'm Susan, sir, the servant,' the girl said tremulously. 'I'd been shopping in Cheapside with my mistress, we – we came back and found the door like this. And upstairs my master and his brother-' She gulped and looked within. 'Oh, God, sir-'

'Where is your mistress?'

'In the kitchen.' She took a deep, whooping breath. 'She went stiff as a board when she saw them, she couldn't move. I sat her down and said I'd go for help, but when I got to the door I felt faint, I couldn't go another step.' She clung to Barak.

'You're a brave girl, Susan,' he said. 'Now, can you take us to your mistress?'

The girl let go of the door. She shuddered at the sight of the bloody footsteps inside, then swallowed and, clutching Barak's hand tightly, led the way down the corridor.

'Two people, by the look of those prints,' I said. 'A big man and a smaller one.'

'I think we're in the shit here.' Barak murmured.

We followed Susan into a large kitchen with a view onto a stone-flagged yard. The room was dingy, the fireplace black with dirt and stains of rats' piss on the whitewashed ceiling. It struck me that Gristwood's schemings had brought him little profit. A woman sat at a big table worn with years of use. She was small and thin, older than I would had expected, wearing a white apron over a cheap dress. Straggles of grey hair were visible under her white coif. She sat rigidly, her hands clutching the table edge, her head trembling.

'She's shocked out of her wits, poor soul,' I whispered.

The servant crossed to her. 'Madam,' she said hesitantly. 'Some men have come. To help us.'

The woman jerked and stared at us wildly. I raised a soothing hand. 'Goodwife Gristwood?'

'Who are you?' she asked. Something sharp and watchful came into her face.

'We came on some business with your husband and his brother. Susan said you came home and found the place broken into-'

'They're upstairs,' Goodwife Gristwood whispered. 'Upstairs.' She clutched her bony hands together so hard the knuckles whitened.

I took a deep breath. 'May we see?'

She closed her eyes. 'If you can bear it.'

'Susan, stay here and look after your mistress. Barak?'

He nodded. If he was feeling the same shock and fear as I, he gave no sign. As we turned to the door, Susan sat down and hesitantly took her mistress's hand.

We passed the tapestry, which I saw from the style was very ancient, and mounted a narrow wooden staircase to the first floor. The house's lopsidedness was noticeable here, some of the stairs were warped and a large crack ran down the wall. There were more bloody footsteps, wet and glinting – this blood had been shed very recently.

At the top of the stairs a number of doors gave off the hallway. They were closed except for the one straight ahead of us. Like the front door it hung off one hinge, the lock smashed in. I took a deep breath and stepped inside.

The chamber was large and well lit, running the whole length of the house. There was an odd, sulphurous smell in the air. I saw the ceiling's large beams were painted with Latin texts. 'Aureo hamo piscari,' I read. To fish with a golden hook.

No one would fish here again. A man in a stained alchemist's robe lay sprawled on his back over an upturned bench amid a chaos of broken glass pipes and retorts. His face had been completely smashed in; one blue eyeball glared at me from the hideous pulpy mess. I felt my stomach heave and turned quickly to study the rest of the room.

The whole workshop was in chaos, more overturned benches, broken glass everywhere. Next to a large fireplace lay the remains of a large iron-bound chest. It was little more than a heap of broken spars now, the metal bands smashed right through. Whoever had wielded the axe here – and everything pointed to an axe – must have had unusual strength.

Beside the chest Michael Gristwood lay on his back, his body half-covered by a blood-soaked chart of the astral planes that had fallen from the wall. His head was almost severed from his neck; a great spray of arterial blood had stained the floor and even the walls. I blenched again.

'That the lawyer?' Barak asked.

'Ay.' Michael's eyes and mouth were wide open in a last scream of astonished terror.

'Well, he won't be needing Lord Cromwell's bag of gold,' Barak said. I frowned. He shrugged. 'Well, he won't, will he? Come on, let's go back downstairs.'

With a last glance at the butchered remains, I followed him down to the kitchen. Susan seemed to have recovered herself somewhat and was boiling a pan of water on the filthy range. Goodwife Gristwood still sat with her hands clenched.

'Anyone else live here, Susan?' Barak asked.

'No, sir.'

'Is there anyone that could come and sit with you?' I asked Goodwife Gristwood. 'Any other relatives?' Again a momentary sharpness came into her face, then she answered, 'No.'

'Right,' Barak said bluntly. 'I'm going to the earl. He must say what's to be done here.'

'The constable should be told-'

'Pox on the constable. I'm going to the earl now.' He pointed at the women. 'Stay here with them, make sure they don't leave.'

Susan looked up anxiously. 'Do you mean Lord Cromwell, sir? But, sir – but we've done nothing.' Her voice rose in fear.

'Do not worry, Susan,' I said gently. 'He must be told. He-' I hesitated.

Goodwife Gristwood spoke, her voice cold and hard. 'My husband and Sepultus were working for him, Susan. I know that much, I told them they were fools, that he's dangerous. But Michael would never listen to me.' She fixed us with pale blue eyes that were suddenly full of anger. 'Now see what's become of him and Sepultus. The fools.'

'God's bones, woman,' Barak burst out. 'Your husband's lying slain in his gore upstairs. Is that all you have to say about him?' I looked at him in surprise, then realized that under his bravado he too was shocked by what we had seen. Goodwife Gristwood merely smiled bitterly and turned her head away.

'Stay here,' Barak told me again. 'I'll be back soon.' He turned and left the kitchen. Susan gave me a scared look; Goodwife Gristwood had retreated into herself.

'It's all right, Susan,' I said with an attempt at a smile. 'You're not in any trouble. There may be a few questions for you, that's all.' She still looked frightened: that was the effect Cromwell's name had on most people. I set my teeth. What in God's name had I got involved in? And who was Barak to give me orders?
