'Why did you burn Margot Haden's property?'
'I've told you that, it was tawdry, only cheap items. I thought she had eloped and wouldn't need them any more.'
Athelstan's heart sank: just a flicker of the eye but he was sure she was lying.
'Did Bartholomew Menster ever offer to marry you?'
'Of course not!'
'Were you jealous of his affection for Margot?'
She shook her head, and Athelstan sensed she was telling the truth.
'Did Bartholomew Menster ever discuss with you the legends of Bishop Gundulf's treasure, about it being like the sun?' He paused. 'And hidden beneath the sun.'
Athelstan abruptly recalled that no reference to the latter half of this cryptic riddle had been found in the manuscripts he had taken from the Tower.
Kathryn was now agitated, rubbing her hands together.
'The Tower is full of such legends,' she replied. 'Hidden gems, lost jewels, Gundulf's treasure hoard, Roman silver.'
'Did you and your late husband Stephen know about these lost treasures of the Tower?'
'Of course. We lived within bowshot of the Tower. Stephen was always buying artefacts from the garrison: shields, disused weapons and other curiosities. You've seen most of them yourself! True, Bartholomew discussed the legends with me but I just laughed.'
'Did he ever offer to buy the Paradise Tree?' Sir John broke in.
Kathryn was about to deny that.
'He did, didn't he?' Athelstan persisted.
'On two occasions,' she replied slowly, 'he made an offer but I refused.'
'And you never thought it strange,' Athelstan asked, 'that a clerk, a scribe from the Tower, was interested in the tavern? Didn't you think his interest in the treasure was, perhaps, more than a passing mood?'
'He made offers. I refused and that's the end of the matter.'
'Well, perhaps we have some good news,' Athelstan said. 'The other skeletons were probably victims of the plague: Black Meadow may have been a burial pit when the great pestilence raged.'
Kathryn smiled. 'It's possible. Perhaps that's why it was called Black Meadow.' She wiped her mouth on the back of her hand. 'Stephen always talked about ghosts being seen there.'
'More than ghosts, mistress. The Four Gospels, that strange little company whom you so generously allowed to stay in Black Meadow, have reported barges coming in on the mud flats. Of dark shapes and shadows entering Black Meadow in the direction of the Paradise Tree.'
'I know nothing of that,' she retorted sharply. 'The Thames is like any highway, both good and bad travel there.'
'But where do they go to?' Athelstan asked.
'Petty Wales is a den of thieves.'
Athelstan fought to control his temper.
'Mistress Vestler, in this gatehouse is a serjeant-at-law, Master Odo Whittock. He and Sir Henry Brabazon are, to use Sir John's term, "two cheeks of the same face". They will dig and dig deeply. They will not be satisfied by your answers in court.'
'It's the only response they will get, Brother.'
'Mistress Vestler, I am trying to help. I have been to the Paradise Tree and it's a fine, prosperous tavern. Questions will be asked about your profits.'
'I am a good businesswoman,' she insisted. 'Brother, if I could have a cup of water?'
Athelstan rose, filled a cracked pewter cup and passed it over.
'My profits are what they are.' She sipped at the water. 'I can say no more.'
Athelstan saw his despair mirrored in Sir John's eyes.
'In which case, Mistress Vestler, I will pray for you and do what I can.'
'I will stay,' Hengan said. 'I need to talk about further matters.'
Sir John went across and hammered on the door.
The turnkey waiting on the other side opened it. They went down the steps and out into the cobbled yard. Athelstan plucked at the coroner's sleeve.
'It does not look well, Sir John.'
'No, Brother, it doesn't.' He paused at a scream which came from a darkened doorway. 'Hell's kitchen! That's what this place is: let's be gone!'
Outside the main gate, Henry Flaxwith stood holding a slavering, smiling Samson in his arms.
'You see, Sir Jack, he's well enough now.'
The dog lunged at Sir John, teeth bared.
'Samson is so pleased to see you, Sir John. You know he loves you.'
'Master Flaxwith, I'll take your word for it. Now, put the bloody thing down!'
Flaxwith lowered Samson gently down on to the cobbles and the ugly mastiff pounced on a scrap of meat from the fleshers' yard.
'And my errand?' Athelstan asked. 'To Hilda Smallwode?'
Flaxwith pulled a face. 'I am not too sure whether you will like this. The maid, who is honest enough, said she did not see Master Sholter actually leave, she was in the house. Her mistress stayed for a while but she did send Hilda upstairs to the bedchamber. The maid remembers seeing the St Christopher on a stool but didn't think anything of it. She certainly saw it again on Sunday morning when she called round to see if her mistress was well.'
Athelstan closed his eyes and quietly cursed.
'Well, well, Brother.' Sir John patted him on the shoulder. 'It would seem your theory will not hold up. Master Sholter did forget his St Christopher.'
Athelstan just rubbed the side of his face. 'Sir John, I must think while you must see your poppets.'
And, hitching his chancery bag over his shoulder, Athelstan despondently walked away, leaving a bemused coroner behind him.
Athelstan trudged on, oblivious to the crowds around him, to the constant shouts of the apprentices: 'What do you lack? What do you lack?' Tradesmen plucking at his sleeve, trying to attract his attention; whores flouncing out of doorways. All the little friar could think of was Mistress Vestler sitting there, telling lies while, across the city, two assassins hugged themselves in glee at the terrible crimes they had committed.
Athelstan paused, breathed in and coughed; the friar was suddenly aware that he had gone through the old city gates. He was now near the great Fleet Ditch which stank to high heaven of the saltpetre which covered the mounds of rubbish. Two urchins ran up, saying they would sing him a song for a penny. Athelstan tossed them a coin and sketched a blessing in the air.
'I'll give you that for silence,' he told them. 'Blackfriars!' he announced. 'I'll go to Blackfriars!'
'And then to heaven?' a chapman who had overheard him called out.
Athelstan smiled and walked on, lost in his thoughts and what he had learned.
At last he arrived at the mother house. A lay brother let him through the postern door. Athelstan seized him by the shoulders and stared into the man's vacant eyes, the saliva drooling from slack jaws.
'It's Brother Eustace, isn't it?'
'Abbot Eustace to you,' the lay brother replied.
Athelstan squeezed the old man's shoulder.
'And I am the Cardinal Bishop of Ostia,' he hissed. 'I've come to make a secret visitation, so don't tell anyone I'm here.'
The lay brother chortled with glee. Athelstan moved on across the cloister garth and into the heavy oak scriptorium and library. The old librarian was not there. Athelstan quietly thanked God, otherwise it would have been at least an hour of gossip and chatter. The assistant, a young friar who introduced himself as Brother Sylvester, welcomed him with the kiss of peace.
'I've heard of you, Brother Athelstan. They say when you were a novice you ran away to war.' The words came out in a rush. 'And your brother was killed and you came back and so they made you parish priest in Southwark.'
'Everyone knows my story.' Athelstan grinned. 'But, Brother, I am in a hurry. Is it possible to have a history of the Tower and the Book of the Dead?'
