Again they pressed, watching the small door close when Athelstan pushed the apple between the serpent and Eve. He pushed and it re-opened. Slowly they approached the cavity, each trying to control his excitement. Athelstan put his hand gingerly into the small, dark space and brought out two rolls of parchment. He ignored Cranston's excited pleas to hurry and went over to the window, unrolling them carefully. The first was a love poem written in a rough hand in Norman French. At first Athelstan thought it was addressed to a woman but realised it was written to a young man. He handed it over to Cranston.
'Make of that what you wish!'
The second was a small indenture or agreement. The top was perforated, so someone else must have a copy. Athelstan read and knew why John of Gaunt, Duke of Lancaster, was so indebted to Sir Thomas Springall, and why the merchant had possessed secrets which could have brought him even greater wealth. Cranston had already dismissed the poem, but when he read the indenture he sat at the foot of the bed stupefied, the parchment held loosely between his fingers.
'This was written fourteen months ago,' he said quietly. 'As the Black Prince, father of the present king, lay dying. If the Lord Edward had known this, he would have had John of Gaunt's head on a pole on London Bridge. If it was revealed now there would be a public outcry.'
'So we know the reasons for SpringalPs death,' Athelstan said, 'but not the hows, the wherefores, and above all the culprit or culprits. Look, Sir John, let's follow the method of the Schools at Oxford. You sit on the bed, I'll sit beside you. You will recite everything you know about each of the four murders, beginning with Sir Thomas Springall's. Though in fact there was another killing, making five in all.' He pointed to the parchment poem. 'The young boy who died here must also be regarded as a victim.'
And so they began, Cranston occasionally pausing for refreshment as he recited in an almost sing-song voice what they knew about Springall's death, and then Brampton's, Vechey's and Allingham's. Athelstan would correct him and make Cranston repeat the list of facts time and again until the coroner, not famous for his patience, shouted: 'Hell's teeth! What are you doing, Brother? We are wasting time! All we are doing is repeating what we already know.'
'Be patient, Sir John,' Athelstan replied, 'Remember, we are looking for a pattern. In logic when you have a problem, the very words of the puzzle contain the answer. There must be a pattern in each of the murders.' He saw Sir John set his mouth and glare from beneath bushy grey eyebrows. 'Look, there is one murder we know very little about – Vechey's. But three, Allingham's, Brampton's and SpringalPs, we do. There must be common factors, things which link all three. We have already established one: poison. I also suspect Vechey and Brampton were drugged. They would not have allowed people to pluck them up, take them prisoner, tie a noose around their necks and kill them. So we have some matching strands. Let us see if there are more.'
Once again Sir John grudgingly recited the facts they knew. Outside the day drew to a close. Athelstan, now listening with half an ear to Sir John's recitation, looked out of the window and wondered what had happened to Benedicta and Lady Maude. Should they return to escort the ladies? He broke Sir John's concentration by asking but the coroner just glowered.
'The Ladies Benedicta and Maude are well able to look after themselves,' he said. 'You started this, Brother, so we'll see it through to the bitter end. Moreover,' he smiled, 'I asked the young gallant who was sitting by Benedicta to take care of both ladies. I am sure he will.'
Athelstan ground his teeth and glared at the coroner but Sir John smiled sweetly back as if innocent of any devious stratagem. Athelstan again made him repeat all they knew, though this time excluding Sir Thomas Springall's murder. Then he walked over to the window and stared down at the chess board. Absentmindedly he began to count the squares, and his heart quickened.
'There is a pattern, Sir John,' he said softly. 'Yes!' He turned, his lean face bright with excitement. 'There is a pattern!'
'You know who the murderer is, don't you? Come on, you bloody friar!' Cranston roared. 'Tell me! I haven't sat here on this bed like a boy in a schoolroom reciting lists of facts for nothing!'
'Tush, Sir John, patience,' Athelstan replied. 'Let me work it into a pattern. Let me get the proper sequence of events, then I shall tell you what I know and the problem will be resolved. But for now you stay here, examine the indenture, reflect on what you have said. I won't be long!'
Before a bemused Cranston could reply, Athelstan had slipped out of the room, walking gingerly across the noisy Nightingale Gallery, down the stairs and out into Cheap- side. Just in case he met any of the Springall household he went down Friday Street, turning into Bread Street and back up St Mary Le Bow. The church was open. Athelstan went into the nave and sat at the base of a pillar, legs crossed, whilst he stared up at the high altar behind the rood screen. He looked round the cool, beautiful church, at the frescoes on the wall, lectern, and pulpit of exquisitely carved oak. From the stalls in the sanctuary he heard the master assembling the choir, rehearsing the hymns and canticles for the feast of Corpus Christi. Athelstan leaned back, letting his head rest against the coldness of the pillar whilst he stared into the darkness, trying to rearrange what he knew, to make the pattern complete and trap the murderer. This was one occasion when the sons of Cain, the killers, would not turn round and claim with mocking innocence, 'Are we our brother's keepers? We are not responsible because we are innocent,' while the blood of five human beings stained their hands and darkened their souls.
The choir began the beautiful hymn 'Pange Lingua'. Athelstan let his mind and soul be calmed, moved by the rhythmical chanting. At one point the youngest boys, the choir's sopranos, took up the refrain, pure and lucid, filling the entire church with angelic sound.
'Respice. Respice Domine. Look back, oh Lord, look back on us! '
Athelstan muttered the words under his breath. 'Look back, oh Lord,' he prayed. 'Give me wisdom and light. Let me plumb the darkness, root out the wickedness. Let those things that were done in the dark of night be revealed for your justice and that of the king in the full light of day.'
Athelstan meditated for an hour. He saw the irony that here he was in a church, the house of God and gate to heaven, thinking about murder. But gradually the pattern was resolved. The culprits were identified, their motives revealed, and he reluctantly admired their deviousness, the sheer wickedness of their plan. He built his own traps, hedging them about, and, when he was ready, returned to the Springall house.
He found Cranston still resting on Sir Thomas's bed, a cup of claret in his hand, softly singing a lullaby. Athelstan could have sworn he was acting as if there was someone else there. As if he was singing to someone he loved. The friar noticed the coroner's eyes were brimming with tears. He looked away, pretending to stare out of the window as he began to summarise his conclusions. Behind him, Cranston regained control of himself. He listened to the friar describe the motive and the identity of the murderers. At first, the coroner rejected everything his assistant said.
'Too ingenious!' he cried. 'Too clever! Too diabolic!'
Athelstan turned.
'Diabolic, yes. But these murders were crafted in the human soul and decided upon by the human mind even if carried out for malicious, devilish purposes. I think I speak the truth, Sir John.'
Cranston stared moodily down at the floorboards, scuffing his boots over the polished surface. Suddenly the Nightingale Gallery outside creaked and sang. Cranston's hand went towards his dagger and Athelstan rapidly approached the door. It was only the old servant, deeper in his cups than Cranston. He staggered and leaned on the door post.
'You have been here a long time, masters. Are you staying? Waiting for Sir Richard?'
'No,' Cranston replied, 'I have told you already. We are here on the regent's orders!' He lifted the wine cup and drained it. 'But I do thank you for your hospitality, sir. I shall remember it.'
'Oh,' Athelstan added, 'is it possible that I could speak to one of the laundresses?'
The servant looked surprised. He blinked but agreed, and some time later ushered a scared girl into the room. She became even more frightened as Athelstan outlined his request and asked her to bring the napkin as soon as possible. When she did Athelstan poured the dregs of the wine over it, cleaned a dusty part of the room and put it beneath his cloak. The maid servant quickly left. Sir John looked bemused.
'What I have done is vital, Sir John,' Athelstan assured him. 'It may well trap the murderers.'
They left the deserted house, the old manservant locking the door behind them, and went down into a deserted Cheapside. Black rain clouds were scudding in over the Thames. It was dark and some of the merchants had lit the lantern-horns outside their doors, whilst Athelstan glimpsed the beacon light shining red and full in the steeple of St Mary Le Bow. They made their way down Friday Street, Old Fish Street and into the Vintry, and hired a wherry at
