The old monk nodded. ‘May he prosper in his love of beauty.’

Without wasting time he climbed with difficulty up a short flight of steps to a small, richly furnished bed chamber. A capacious wooden four-poster had been hauled to one side. The guard who now accompanied them stuck his lantern into the wall rack and bent to heave open a paving slab in the floor with both hands.

Athanasius went to peer down into the vault and Hildegard heard him give a growl of interest.

‘More light,’ he commanded.

The guard lifted the lantern and brought it over. Hildegard and the cardinal joined Athanasius while the guard allowed his light to play over the treasures stacked below. It picked out the sparkle of gems and worked silver, the gleam of gold chalices, crucifixes, coronets, salvers, plate and medals. It shone over innumerable gold ingots piled like softly glowing bricks from floor to ceiling.

‘We are going down. Show us where the body is.’ Athanasius stepped to one side to allow the cardinal to be the first to descend into the treasury.

**

Hildegard leaned in to have a look.

Under the blazing light of the cresset the body, clearly visible between the towers of gold, was lying stiff and awkward on a heap of coins. It was a young man, little older than King Richard himself. Jewels winked all round him from every part of the vault as the cresset flooded the stronghold with light. It flickered and flared over a priceless hoard. Briefly something glimmered in the corpse’s grip.

Athanasius was descending with painful slowness after the more nimble cardinal then he reached the bottom and the two churchmen moved deeper into the treasury, blocking the light, dark to light. When the guard followed them down his light revealed Athanasius beside the body, crouching on a mound of gold coins and peering into the dead youth’s face. With a swift gesture he indicated the light to be brought closer. The guard crunched over scattered gold and raised the torch aloft. In the cone of light they could all see the fatal wound, a single gash from ear to ear, dried blood gleaming like a string of black pearls around his throat.

In one hand he held a small dagger. The hilt was studded with balas rubies and amethysts. It was locked with the fierce rigor of death between the dead man’s fingers. His dilated pupils were set in a fixed stare at something he could no longer see.

Despite all this, Athanasius felt for a heart-beat and inside the dead man’s shirt found a small crucifix on a thin chain. He inspected the finger nails. He glanced at the feet in soft-soled night boots. He noted the silk hose and short jacket of expensive brocade. Hildegard felt her eyes prick at the sadness of it. Amidst such wealth of treasure the body was bereft of what is most precious of all.

‘Certainly dead,’ grunted Athanasius with a swift glance at the cardinal. ‘Four hours or more. Note the rigor of the limbs?’

With the ceiling low the old monk could not stand to his full height. Tall for a man of advanced years, he had to creep crouch-backed over scattered ingots to the wooden steps where he climbed back up, breathing hard, into the pope’s bed-chamber. He growled to Hildegard, ‘Go down, domina, if you’ve the stomach for it. Tell me what you observe.’

Hildegard let herself into the vault. The guard stoically held the light for her and she looked at what the monk had seen. What else was there? What did he expect her to find that he had not already noticed? She stared at the youth. He was probably no more than eighteen or so. A pleasant face, recently shaven. Reddish hair sprouting from his head with a vitality that made his death seem the more unreal. Did he have the features of a thief? Is larceny written across the human face? Is that what Athanasius expected her to discern?

Blood was caked on the coins underneath his head, a king’s ransom to be cleaned in lye by a trusted servant before they could circulate again.

The cardinal, on his knees, was mumbling a blessing with the desperation of a man who thinks words can return the dead to life. Hildegard climbed out and reached the upper chamber with a sense of relief.

After a few moments the cardinal climbed back after her into his lord’s chamber. He put a hand over his face as if the light dazzled him.

‘Come.’ Athanasius ushered Hildegard across the chamber towards the door.

In parting, he touched the cardinal lightly on the sleeve.

‘How was my lady prioress of Swyne when you left England?’

So it was the prioress he had referred to earlier. ‘She was recovering from an ague but otherwise in good spirits, I’m pleased to say.’

‘She gives little away, that one.’ Athanasius lifted his head as an invitation to agree. When nothing was forthcoming he added, ‘Recent events in England cannot please her?’

‘I expect she’s in great distress. Alexander Neville is not only her brother in Christ, but her blood brother too.’

‘Send her my warmest remembrances when you write to her, domina. Meanwhile,’ Athanasius continued, ‘we have the interesting conundrum of why the body of one of our fellow countrymen has been found in Clement’s treasury.’

‘You recognised him?’

‘Cardinal Grizac identified him. He is, or I should say, was, one of his acolytes.’

‘What do you think he was doing inside the treasury?’ Hildegard asked.

‘Allow me to tell you a little about the cardinal who accompanied us, domina. Although now past his prime, he is a younger brother of the old pope who died some while ago, Urban V, last pope before the second Great Schism that has rent the Christian world. Our cardinal is the son of the lord of Bellegarde, Count of Grizac. As you will understand, with these connections, he is a man of some power. In the past he had many significant roles in the papacy. At one time he was even Dean to the Chapter in York and wrote some impressive music for them.’

‘So he would have met Archbishop Neville while in York?’ Later she would ponder this interesting fact and try to make sense of what it might mean, if anything.

Athanasius was smiling. ‘Quite so. But, far more interesting is that he was expected to become pope.’

Hildegard was startled. ‘So he was passed over?’

‘Yes, and entirely because of the exploits of Clement on the battlefield at Cesena while defending the Papal States.’

‘And that event gave the triple crown to Clement instead.’

Athanasius was watching her carefully. ‘To everyone’s surprise, our Cardinal Grizac declared for him. As a consequence the English threw poor Grizac out as an enemy and he lost his preferment in York. He returned to Avignon and was made bishop here, small compensation, one might think, for his earlier brilliance.’

‘Is he content?’

Athanasius gave her a meaningful look that could have meant anything. ‘Since then,’ he continued, ‘apart from a short spell in Rome, he has resided here in the papal palace or across the river on his estate at Villeneuve. The dead youth was brought by him from England as his acolyte. He renamed him Maurice.’ He pronounced it in the French way. ‘Maurice is - was - noted for his singing,’ he added.

That touch on the sleeve. Sharing the cardinal’s grief. It made sense. Athanasius, against appearances, must have a heart.

**

With just a pull at one or two threads, a secret order was beginning to show itself.

Maurice had been recruited in York from the song school in the Minster. He came over with the cardinal to Avignon when the latter was thrown out of England. The cardinal was Anglic of Grizac. He was the bishop of Avignon. Maurice had been about the same age as King Richard and, like him, was a child born into a courtly world of ambition and intrigue. In order to survive he would have had to make his way through a myriad of unseen dangers. Plots and counter plots. The intrigues of the papal court.
