‘Sir John,’ Athelstan stepped back, ‘you are correct. Who was this Lady Purity?’

‘A great courtesan of Cheapside. I used to woo her from afar. She certainly wasn’t for the likes of young Jack Cranston, freshly inducted into the Inns of Court, oh no, but I adored her from a distance, worshipping at her altar. I did all I could to discover more about her.’

‘And?’

‘Lady Purity, as she called herself, reserved her favours for the great ones of the land. She also acquired a rather sinister reputation.’

‘As?’

‘As a cozening blackmailer who, when it suited her, could threaten a cleric with a summons to the Archdeacon’s court or an errant husband with the wrath of his wife. She earned money swiftly and smoothly in both her callings, hence her nickname, “Mistress Quicksilver”. As for her title, “Lady Purity”,’ Cranston laughed, ‘well, that was because of her pious ways, at least publicly. In her youth she was a great beauty who acted so innocently, so decorously, you’d think butter wouldn’t melt in her mouth. She was the toast. .’ Cranston walked away as shouts and cries from outside rose and fell. Athelstan remained rooted to the spot, lost in his own wild tumble of thoughts.

‘As I said,’ Cranston continued, coming back, ‘she was the toast of Cheapside. Athelstan, you were right about her relationship with our abbot, that’s what started me thinking. Eleanor Remiet is not the abbot’s sister but his leman.’ Cranston chuckled to himself. ‘She is definitely the mother of the lovely Isabella who, of course, is the abbot’s natural daughter, certainly not his niece. They are, in the eyes of God, though not Holy Mother Church, husband, wife and child. Lady Purity or Mistress Quicksilver, whatever her name, will have her claws very deep into our Lord Abbot. She will demand the best sustenance and purveyance for both herself and her daughter. In her youth, saintly Susannah or not, Lady Purity had a hunger for gold and silver. The passing of the years and the needs of young Isabella will have only whetted her appetite as sharp as a knife.’

‘Which would explain why the abbot stopped paying the Upright Men?’

‘Aye, and God knows what else he has misappropriated. I think it’s time-’

‘Not yet,’ Athelstan gripped Cranston’s sleeve, ‘not yet my Lord Coroner, let me first reflect; there are other matters. .’

Athelstan broke off as the hubbub outside grew. He and Cranston went through a side door into the porch. A group of brothers were gathered round a barrow being pushed up the path. Exclamations rang out, the monks, jostling each other, blocked Athelstan’s view of what was in the barrow. They parted and Athelstan groaned in sheer pity at the horror piled there, the long graceful neck now twisted, the glorious white plumage piled in dirty disarray — Leda the swan! Athelstan stopped the barrow and stared down at the once magnificent bird.

‘How did it happen?’

‘Hanged! Hanged!’ Brother Simon pushed his way through. ‘We found Leda hanged on the gallows near the watergate.’

Athelstan sketched a blessing over the dead bird.

‘Abbot Walter will be distraught,’ one of the brothers exclaimed. ‘He will mourn as if for a loved one.’

‘Aye, but does he love any of us?’ another added.

The question was greeted with silence.

‘Who? How?’ Athelstan asked.

Another monk passed Athelstan a parchment script with the phrase, ‘Answer a fool according to his folly’ scratched in red ink. Beneath this, ‘The Upright Men’.

‘The Upright Men,’ Athelstan murmured. ‘Where will they flee on the day of judgement?’ He looked at the rough, chapped faces of the brothers who stared stonily back. ‘Jerusalem,’ Athelstan added sadly, ‘will not be built on earth.’

‘But Babylon and its proud princes can be brought as low as hell,’ a lay brother retorted.

‘Like this,’ Athelstan pointed at the dead swan, ‘do you know what the great philosopher Anselm said? “Cruelty to God’s creatures comes directly from the evil one”. Leda was,’ Athelstan continued softly, ‘a manifestation of the glory of God.’ He stood aside. ‘Your Lord Abbot needs to be informed.’ Athelstan returned to Cranston, still standing in the porch, and told him what had happened.

‘Abbot Walter is a fool. Athelstan, please excuse me, I’ve other business to attend to. We’ll then meet and confront Abbot Walter and his Lady Purity.’ Cranston strolled away.

Athelstan watched him go and decided to visit the library. Immediately as he entered two of the monks sitting in their carrels swiftly rose. Courteous, gracious and welcoming, Athelstan sensed they were under strict instruction to keep him occupied, whilst a third brought Richer from the scriptorium. Athelstan informed him about the swan. The Frenchman raised his eyes and murmured a prayer.

‘I am sorry,’ Richer lisped, ‘but at the present I’ve other business to deal with. I will see Father Abbot in due time. I have decided,’ Richer gestured around the library, ‘much as I love it here, to return to St Calliste, as Lord Walter said, sooner rather than later, probably in the next few days.’

‘I am sorry,’ Athelstan shook his head, ‘that will not be possible.’

‘What do you mean — I’m a priest, a Benedictine, a citizen of France. I-’

‘Brother Richer, you could be the kinsman of the Archangel Gabriel. If the Crown of England decides that you must delay your return to France until this business is cleared up then that must be so. No harbour master will allow you out of this realm without proper licence. Now, do you have information here on the bloodstone, the Passio Christi?’

Richer, all flustered, waved the friar to a carrel under a window, further light being provided by a covered candle. Athelstan sat and patiently waited until Richer brought a book, a copy of a work Athelstan recognized from his own order’s library at Blackfriars, ‘The Book of Relics’, a compendium describing the great relics of Christendom and their location. Athelstan opened this and found the entry for the bloodstone, short and succinct, telling him very little more than he already knew. Athelstan stared at the entry and leafed through the pages. A bell sounded. The monks, busy over their manuscripts, paused, rose and filed out. Athelstan glanced down the library. The door to the scriptorium remained closed. Richer had not left. Athelstan extinguished the candles, closed the book and moved into the shadows, searching the shelf from where Richer had taken ‘The Book of Relics’. Athelstan was sure there must be more information than just a few lines in a general compendium.

So hidden in the darkness, Prior Alexander did not see Athelstan as he flung open the library door and hurried down, knocking at the scriptorium and entering even before Richer could reply. Athelstan edged out of the corner and softly approached as near as he could. The prior had not bothered to close the door behind him. He heard Richer ask if Prior Alexander had seen ‘that friar — more of a ferret than a priest?’ Athelstan smiled at that. Prior Alexander ignored the question and began a tirade, highly irate at the prospect of Richer leaving so soon. The prior lost all control, shouting at Richer, asking if he cared, and demanding he tell him the reason why? Athelstan felt guilty yet he stayed, listening to what was really a passionate lovers’ quarrel. Richer tried to defend himself, explaining how he had to go, but the prior was besides himself with jealous rage. The argument grew more heated. Athelstan braced himself as he heard a stool crash over, Richer yelled that the prior let go of his arm. Athelstan was about to intervene when the library door rattled. The friar hastily stepped back into the shadows. A servitor entered, clumsily slipping and slithering on the polished floor, loudly shouting how the Lord Abbot demanded the immediate presence of both his prior and sub-prior in his chamber.

The altercation in the scriptorium swifty subsided. Both monks left, followed by the agitated servitor loudly lamenting how the Lord Abbot was stricken at what had happened to poor Leda. Athelstan waited until they’d gone and stepped out of his hiding place. He was about to continue his searches when he heard Cranston shouting his name. Athelstan sighed and walked to the door. The coroner stood at the far end of the portico gallery which ran down to the library, patting the shoulder of the stranger standing next to him as he gestured at Athelstan to join them.
