I did not see Lancelot for many years after the Round Table oath, nor did I see any of his henchmen. Amhar and Loholt, Arthur’s twins, lived in Lancelot’s capital of Venta where they led bands of spearmen, but the only fighting they seemed to do was in its taverns. Dinas and Lavaine were also in Venta where they presided over a temple dedicated to Mercury, a Roman God, and their ceremonies rivalled the ones held in Lancelot’s palace church that had been consecrated by Bishop Sansum. Sansum was a frequent visitor to Venta and he reported that the Belgic people seemed happy enough with Lancelot, which we took to mean that they were not openly rebellious. Lancelot and his companions also visited Dumnonia, most often going across their border to the Sea Palace, but sometimes travelling as far as Durnovaria to attend some high feast, but I simply stayed away from such festivals if I knew they were coming, and neither Arthur nor Guinevere ever demanded that I attend. Nor was I invited to the great funeral that followed the death of Lancelot’s mother, Elaine. Lancelot, in truth, was not a bad ruler. He was no Arthur, he cared nothing for the quality of justice or the fairness of taxes or the state of the roads, he simply ignored those things, but as they had been ignored before his rule no one noticed any great difference. Lancelot, like Guinevere, cared only for his comfort and, like her, he built a lavish palace that was filled with statues, bright with painted walls and hung, of course, with the extravagant collection of mirrors in which he could admire his own endless reflection. The money for these luxuries was exacted in taxes, and if those taxes were heavy then the compensation was the freedom of the Belgic lands from Saxon raids. Cerdic, astonishingly, had kept his faith with Lancelot and the dreaded Sais spearmen never raided Lancelot’s rich farmlands. But nor did they need to raid, for Lancelot had invited them to come and live in his kingdom. The land had been depopulated by the long years of war and huge stretches of fine fields were growing back to woodland, and so Lancelot invited settlers from Cerdic’s people to till the fields. The Saxons swore oaths of loyalty to Lancelot, they cleared the land, they built new villages, they paid their taxes, and their spearmen even marched in his war-band. His palace guard, we heard, were all Saxons now. The Saxon Guard, he called them, and he chose them for their height and for the colour of their hair. I did not see them in those years, though eventually I met them, and they were all tall blond men who carried axes polished to a mirror brightness. Rumour had it that Lancelot paid tribute to Cerdic, but Arthur angrily denied it when our Council asked him if it was true. Arthur disapproved of Saxon settlers being invited onto British land, but the matter, he said, was Lancelot’s to decide, not ours, and at least the land was at peace. Peace, it seemed, excused all.

Lancelot even boasted that he had converted his Saxon Guard to Christianity, for his baptism, it seems, had not just been for show, but was real enough, or so Galahad told me on one of his frequent visits to Lindinis. He described the church Sansum had built in the Venta palace and told me that every day a choir sang and a bevy of priests celebrated the Christian mysteries. ‘It’s all very beautiful,’ Galahad said wistfully. That was before I had seen the ecstasies in Isca and I had no idea such frenzies took place, so did not ask him whether they happened in Venta, or whether his brother encouraged Dumnonia’s Christians to see him as a deliverer.

‘Has Christianity changed your brother?’ Ceinwyn asked.

Galahad watched the flicker of her hands as she teased a thread from the distaff onto the spindle.

‘No,’ he admitted. ‘He thinks it’s enough to say prayers once a day and then he behaves as he likes thereafter. But many Christians are like that, alas.’

‘And how does he behave?’ Ceinwyn asked.

‘Badly.’

‘Do you want me to leave the room,’ Ceinwyn asked sweetly, ‘so you can tell Derfel without embarrassing me? And then he can tell me when we go to bed.’

Galahad laughed. ‘He’s bored, Lady, and he alleviates his boredom in the usual way. He hunts.’

‘So does Derfel, so do I. Hunting’s not bad.’

‘He hunts girls,’ Galahad said bleakly. ‘He doesn’t treat them badly, but they don’t really have much choice. Some of them like it and they all become rich enough, but they also become his whores.’

‘He sounds like most kings,’ Ceinwyn said drily. ‘Is that all he does?’

‘He spends hours with those two wretched Druids,’ Galahad said, ‘and no one knows why a Christian King would do that, but he claims it’s just friendship. He encourages his poets, he collects mirrors and he visits Guinevere’s Sea Palace.’

‘To do what?’ I asked.

‘To talk, he says.’ Galahad shrugged. ‘He says they talk about religion. Or rather they argue about it. She’s become very devout.’

‘To Isis,’ Ceinwyn said disapprovingly. In the years after the Round Table oath we had all heard how Guinevere was retreating more and more into the practice of her religion so that now the Sea Palace was said to be one huge shrine to Isis, and Guinevere’s attendants, who were all women chosen for their grace and looks, were the priestesses of Isis.

‘The Supreme Goddess,’ Galahad said disparagingly, then carefully crossed himself to keep the pagan evil at bay. ‘Guinevere evidently believes the Goddess has enormous power that can be channelled into human affairs. I can’t imagine Arthur likes it.’

‘He’s bored by it all,’ Ceinwyn said, spinning the last of the thread off the distaff and laying it down.

‘All he ever does now,’ she went on, ‘is complain that Guinevere won’t talk to him about anything except her religion. It must be horribly tedious for him.’ This conversation took place long before Tristan fled to Dumnonia with Iseult, and when Arthur was still a welcome guest at our house.

‘My brother claims to be fascinated by her ideas,’ Galahad said, ‘and maybe he is. He claims she’s the most intelligent woman in Britain and says he won’t marry till he finds another just like her.’

Ceinwyn laughed. ‘A good job he lost me, then. How old is he now?’

‘Thirty-three, I think.’

‘So ancient!’ Ceinwyn said, smiling at me, for I was only a year younger. ‘What happened to Ade?’

‘She gave him a son, and died doing it.’

‘No!’ Ceinwyn said, upset as always at hearing of a death in childbirth. ‘And you say he has a son?’

‘A bastard,’ Galahad said disapprovingly. ‘Peredur, he’s called. Four years old now, and not a bad little boy. In truth I rather like him.’

‘Has there ever been a child you didn’t like?’ I asked him drily.

‘Brush-head,’ he said, and we all smiled at that old nickname.

‘Imagine Lancelot having a son!’ Ceinwyn said with that intonation of surprised import with which women greet such news. To me the existence of another royal bastard seemed entirely unremarkable, but men and women, I notice, respond to these things quite differently.

Galahad, like his brother, had never married. Nor did he have land, but he was happy and was kept busy serving as an envoy for Arthur. He tried to keep the Brotherhood of Britain alive, though I noticed how quickly those duties fell away, and he travelled through all the British kingdoms, carrying messages, settling disputes and using his royal rank to ease whatever problems Dumnonia might have with other states. It was usually Galahad who travelled to Demetia to curb Oengus Mac Airem’s raids on Powys and it was Galahad who, after Tristan’s death, carried the news of Iseult’s fate to her father. I did not see him after that, not for many months.

I tried not to see Arthur either. I was too angry with him, and I would neither answer his letters nor go to the Council. He came to Lindinis twice in the months after Tristan’s death and both times I was coldly polite and both times I left him as soon as I could. He did talk for a long time with Ceinwyn and she tried to reconcile us, but I could not shake the thought of that burning child from my head. But nor could I ignore Arthur altogether. Mordred’s second acclamation was now just months away and the preparations had to be made. The ceremony would be held at Caer Cadarn, just a short walk east of Lindinis, and inevitably Ceinwyn and I were drawn into the planning. Mordred himself even took an interest, perhaps because he realized that the ceremony would at last free him of all discipline. ‘You have to decide,’ I told him one day, ‘who will acclaim you.’

‘Arthur will, won’t he?’ he asked sullenly.

‘It’s usually done by a Druid,’ I said, ‘but if you want a Christian ceremony then you must choose between Emrys or Sansum.’

He shrugged. ‘Sansum, I suppose.’

‘Then we should go and see him,’ I said.

We went on a hard midwinter day. I had other business in Ynys Wydryn, but first went with Mordred to the Christian shrine where a priest told us that Bishop Sansum was busy saying mass and that we must wait. ‘Does he know his King is here?’ I demanded.

‘I shall tell him, Lord,’ the priest said, and scuttled away across the frozen ground. Mordred had wandered off to stand beside his mother’s grave where, even on that cold day, a dozen pilgrims knelt in worship. It was a very simple grave, nothing but a low mound of earth with a stone cross that was dwarfed by the lead urn Sansum had placed to receive the pilgrims’ offerings. ‘The Bishop will be with us soon,’ I said. ‘Shall we wait inside?’

He shook his head and frowned at the low grassy mound. ‘She should have a better grave,’ he said.

‘I think that’s true,’ I said, surprised he had spoken at all. ‘You can build it.’

‘It would have been better,’ he said snidely, ‘if others had paid her that respect.’

‘Lord King,’ I said, ‘we were so busy defending the life of her child that we had small time to worry about her bones. But you are right, and we were remiss.’

He kicked moodily at the urn, then peered inside to see the small treasures that had been left by the pilgrims. Those who were praying at the grave edged away, not for fear of Mordred whom I doubt they even recognized, but because the iron amulet I wore about my neck betrayed that I was a pagan. ‘Why was she buried?’ Mordred suddenly asked me. ‘Why wasn’t she burned?’

‘Because she was a Christian,’ I said, hiding my horror at his ignorance. I explained that Christians believed their bodies would be used again at the final coming of Christ, while we pagans took new shadowbodies in the Otherworld and thus had no need of our corpses which, if we could, we burned to prevent our spirits wandering the earth. If we could not afford a funeral pyre then we burned the dead person’s hair and cut off one foot.

‘I shall make her a vault,’ he said when I had finished my theological explanation. He asked me how his mother had died and I told him the whole story of how Gundleus of Siluria had treacherously married Norwenna, then murdered her as she knelt to him. And I told him how Nimue had taken her revenge on Gundleus.

‘That witch,’ Mordred said. He feared Nimue, and no wonder, for she was becoming ever fiercer, ever gaunter and ever dirtier. She was a recluse now, grubbing a life in the remnants of Merlin’s compound where she chanted her spells, lit fires to her Gods and received few visitors, though once in a while, unannounced, she would stride into Lindinis to consult with Merlin. I would try to feed her on those rare visits, the children would run from her, and she would walk away, muttering to herself with her one eye wild, her robe caked with mud and ashes, and her matted black hair tangled with filth. Beneath her refuge on the Tor she was forced to watch the Christian shrine grow larger, stronger and ever more organized. The old Gods, I thought, were losing Britain fast. Sansum, of course, was desperate for Merlin to die so he could take the Tor for himself and build a church on its fire-scarred summit, but what Sansum did not know was that all Merlin’s land was willed to me.

Mordred, standing beside his mother’s grave, wondered at the similarity of names between my eldest daughter and his dead mother and I told him that Ceinwyn was Norwenna’s cousin. ‘Morwenna and Norwenna are old names in Powys,’ I explained.

‘Did she love me?’ Mordred asked, and the incongruity of that word in his mouth gave me pause. Maybe, I thought, Arthur was right. Maybe Mordred would grow into his responsibilities. Certainly, in all the years I had known him, I had never held such a courteous discussion before.

‘She loved you very much,’ I answered truthfully. ‘The happiest I ever saw your mother,’ I went on,

‘was when you were with her. It was up there.’ I pointed to the black scar where Merlin’s hall and his dream-tower had stood on the Tor. It was there that Norwenna had been murdered and Mordred had been snatched away from her. He had been a baby then, even younger than I had been when I was snatched from my mother, Erce. Did Erce still live? I still had not travelled to Siluria to find her, and that omission made me feel guilty. I touched the iron amulet.

‘When I die,’ Mordred said, ‘I want to be in the same grave as my mother. And I’ll make the grave myself. A vault of stone,’ he declared, ‘with our bodies lifted on a pedestal.’

‘You must talk to the Bishop,’ I said, ‘and I’m sure he’ll be pleased to do whatever he can to help.’

So long, I thought cynically, as he did not have to pay for the vaulted sepulchre. I turned as Sansum hurried across the grass. He bowed to Mordred, then welcomed me to the shrine.

‘You come, I hope, in search of truth, Lord Derfel?’

‘I come to visit that shrine,’ I said, pointing to the Tor, ‘but my Lord King has business of his own with you.’ I left them there alone and led my horse up to the Tor, passing by the group of Christians who, day and night, prayed at the Tor’s foot that its pagan inhabitants would be driven away. I endured their insults, then climbed the steep hill to discover that the water-gate had fallen from its last hinge. I tied my horse to a stake in what remained of the palisade, then carried the bundle of clothes and furs that Ceinwyn had packed so that the poor folk who shared Nimue’s refuge would not freeze in the bitter weather. I gave Nimue the clothes and she dropped them carelessly in the snow, then plucked at my sleeve and drew me into her new hut that she had built exactly where Merlin’s dream-tower had once stood. The hut stank so foully that I almost gagged, but she was oblivious to its mephitic stench. It was a freezing day and an icy sleet was whipping out of the east on a damp wind, yet even so I would rather have stood in the freezing downpour than endure that reeking hut. ‘Look,’ she said proudly, and showed me a cauldron, not the Cauldron, but just a common, patched iron cauldron that hung from a roof beam and was filled with some dark liquid. Sprigs of mistletoe, a pair of bat wings, the sloughed skin of snakes, a broken antler and bunches of herbs also hung from the rafters that were so low that I had to bend double to get inside the hut, which was eye-stingingly full of smoke. A naked man lay on a pallet in the far shadows and complained about my presence.

‘Quiet,’ Nimue snarled at him, then she took a stick and poked it into the cauldron’s dark liquid which steamed gently above a small fire that was generating far more smoke than heat. She stirred the cauldron about, found whatever she wanted and levered it up from the liquid. I saw it was a human skull. ‘You remember Balise?’ Nimue asked me.

‘Of course,’ I said. Balise had been a Druid, an old man when I was young, and now long dead.

‘They burned his body,’ Nimue told me, ‘but not his head, and a Druid’s head, Derfel, is a thing of awesome power. A man brought it to me last week. He had it in a barrel of beeswax. I bought it from him.’

Which meant I had purchased the head. Nimue was forever buying objects of cultic power: the caul of a dead child, the teeth of a dragon, a piece of the Christian’s magical bread, elf bolts, and now a dead man’s head. She used to come to the palace and demand the money for these tawdry things, but I now found it easier to leave her with a little gold, even if it did mean that she would waste the metal on whatever oddity was offered her. She once paid a whole gold ingot for the carcass of a lamb that had been born with two heads, and she had nailed the carcass to the palisade where it overlooked the Christian shrine and there let it rot. I did not like to ask what she had paid for a barrel of wax containing a dead man’s head. ‘I stripped the wax away,’ she told me, ‘and boiled the flesh off the head in the pot.’

That in part explained the hut’s overwhelming stench. ‘There is no more powerful augury,’ she told me, her one eye glinting in the dark hut, ‘than a Druid’s head seethed in a pot of urine with the ten brown herbs of Crom Dubh.’ She let the skull go and it sank beneath the liquid’s dark surface. ‘Now, wait,’ she ordered me.

My head was reeling with the smoke and stench, but I obediently-waited as the liquid’s surface shivered, glinted and finally subsided until it was nothing but a dark sheen as smooth as a fine mirror with only a hint of steam drifting from its black surface. Nimue leaned close and held her breath, and I knew she was seeing portents in the liquid’s surface. The man on the pallet coughed horribly, then feebly clawed at a threadbare blanket to half cover his nakedness. ‘I’m hungry,’ he whined. Nimue ignored him. I waited. ‘I’m disappointed in you, Derfel,’ Nimue suddenly said, her breath just wrinkling the liquid’s surface.

‘Why?’

‘I see a Queen was burned to death on a seashore. I would have liked her ashes, Derfel,’ she said reprovingly. ‘I could have used a Queen’s ashes,’ she went on. ‘You should have known that.’ She fell silent and I said nothing. The liquid was still again, and when Nimue next spoke it was in a strange, deep voice that did not blur the black liquid’s surface at all. ‘Two Kings will come to Cadarn,’ she said, ‘but a man who is no King shall rule there. The dead will be taken in marriage, the lost will come to the light and a sword will lie on the neck of a child.’ Then she screamed terribly, startling the naked man who scuttled frantically into the furthest corner of the hut where he crouched with his hands covering his head. ‘Tell that to Merlin,’ Nimue said to me in her normal voice. ‘He’ll know what it means.’

‘I will tell him,’ I promised her.

‘And tell him,’ she said with a desperate fervour, clutching my arm with a dirt-encrusted claw of a hand, ‘that I have seen the Cauldron in the liquid. Tell him it will be used soon. Soon, Derfel! Tell him that.’

‘I will,’ I said, and then, unable to take the smell any more, I pulled away from her grip and backed out into the sleet.

She followed me out of the hut and plucked a wing of my cloak to cover herself from the sleet. She walked with me towards the broken water-gate and was oddly cheerful. ‘Everyone thinks we’re losing, Derfel,’ she said, ‘everyone thinks those filthy Christians are taking over the land. But they’re not. The Cauldron will be revealed soon, Merlin will be back and the power will be loosed.’

I stopped in the gate and stared down at the group of Christians who were always gathered at the foot of the Tor to pray their extravagant prayers with their arms spread wide. Sansum and Morgan arranged for them to be there so that their constant prayers might serve to drive the pagans off the Tor’s fire-scarred summit. Nimue stared scornfully down at the group. Some of the Christians recognized her and made the sign of the cross. ‘You think Christianity is winning, Derfel?’ she asked me.

‘I fear it,’ I said, listening to the howls of rage from the Tor’s foot. I remembered the frenzied worshippers in Isca and wondered how long the horror of that fanaticism could be kept under control. ‘I do fear it is,’ I said sadly.

‘Christianity isn’t winning,’ Nimue said scornfully. ‘Watch.’ She ducked out from under my cloak and lifted her dirty dress to expose her wretched nakedness to the Christians, and then she thrust her hips obscenely towards them and gave a wailing cry that died in the wind as she dropped the dress. Some of the Christians made the sign of the cross, but most, I noted, instinctively made the pagan sign against evil with their right hands and then spat on the ground. ‘You see?’ she said with a smile, ‘they still believe in the old Gods. They still believe. And soon, Derfel, they will have proof. Tell that to Merlin.’

I did tell Merlin. I stood before him and reported that two Kings would come to Cadarn, but a man who was not a King would rule there, that the dead would be taken in marriage, the lost would come to the light and a sword be laid on the neck of a child.

‘Say it again, Derfel,’ he said, squinting up at me and stroking an old tabby cat that was stretched out on his lap.

I repeated it all solemnly, then added Nimue’s promise that the Cauldron would soon be unveiled and that its horror was imminent. He laughed, shook his head, then laughed again. He soothed the cat on his lap. ‘And did you say she had a Druid’s head?’ he asked.

‘Balise’s head. Lord.’

He tickled the cat under the chin. ‘Balise’s head was burned, Derfel, years ago. It was burned, then pounded into a powder. Pounded to nothing. I know, because I did it.’ He closed his eyes and slept. Next summer, on the eve of a full moon, when the trees that grew about the foot of Caer Cadarn were heavy with leaf, on a morning of brilliant sunshine that shone on hedgerows bright with bryony and bindweed and willowherb and old man’s beard, we acclaimed Mordred our King on the ancient summit of the Caer.

Caer Cadarn’s old fortress stood deserted for much of the year, but it was still our hill of kingship, the solemn place of ritual at Dumnonia’s royal heart, and the fort’s ramparts were kept strong, but the interior of the fort was a sad place of decaying huts that crouched around the big gaunt feasting hall that was a home to birds, bats and mice. That hall occupied the lower part of Caer Cadarn’s wide summit, while on the higher part, to the west, stood a circle of lichen-covered stones surrounding the grey, slab-like boulder that was Dumnonia’s ancient stone of kingship. Here the great God Bel had anointed his half-God, half-human child Beli Mawr as the first of our Kings and ever since, even in the years when the Romans had ruled, our Kings had come to this place to be acclaimed. Mordred had been born on this hill and here too he had been acclaimed as a baby, though that ceremony had merely been a sign of his kingly status and had placed no duties on him. But now he was at the dawn of his manhood and from this day on he would be King in more than name. This second acclamation discharged Arthur’s oath and gave Mordred all of Uther’s power.

The crowds gathered early. The feasting hall had been swept, then hung with banners and decorated with green boughs. Vats of mead and pots of ale were set on the grass, while smoke poured from the great fires where oxen, pigs and deer were being roasted for the feast. Tattooed tribesmen from Isca mingled with the elegant, toga-clad citizens from Durnovaria and Corinium, and both listened to the white-robed bards who sang specially composed songs praising Mordred’s character and forecasting the glories of his reign. Bards never were to be trusted.

I was Mordred’s champion and so, alone among the lords on the hill, I was dressed in my full war gear. It was no longer the shabby, ill-repaired stuff I had worn at that fight outside London, for now I possessed a new and expensive armour that reflected my high status. I had a coat of fine Roman mail that was trimmed with golden rings at its neck, hem and sleeves. I had knee-high boots that gleamed with bronze strips, elbow-length gloves lined with iron plates that protected my forearms and fingers, and a fine silver-chased helmet with a mail flap that protected the back of my neck. The helmet had cheek pieces that hinged across my face and a gold finial from which my freshly brushed wolf-tail hung. I had a green cloak, Hywelbane at my hip and a shield which, in honour of this day, bore Mordred’s red dragon instead of my own white star.

Culhwch had come from Isca. He embraced me. ‘This is a farce, Derfel,’ he growled.

‘A great and happy day, Lord Culhwch,’ I said, straight-faced.

He did not smile, but instead looked sullenly about the expectant crowd. ‘Christians,’ he spat.

‘There do seem a lot of them.’

‘Is Merlin here?’

‘He felt tired,’ I said.

‘You mean he’s got more sense than to come,’ Culhwch said. ‘So who does the honours today?’

‘Bishop Sansum.’

Culhwch spat. His beard had gone grey in the last few months and he moved stiffly, though he was still a great bear of a man. ‘Are you talking to Arthur yet?’ he demanded.

‘We speak when we have to,’ I answered evasively.

‘He wants to be friends with you,’ Culhwch told me.

‘He deals very strangely with friends,’ I said stiffly.

‘He needs friends.’

‘Then he’s lucky to have you,’ I retorted, and turned as a horn-call interrupted our conversation. Spearmen were making a passage in the crowd, using their shields and spear-staffs to press the people gently back, and in the spearmen’s corridor a procession of lords, magistrates and priests walked slowly towards the ring of stones. I took my place in the procession alongside Ceinwyn and my daughters. The gathering that day was a tribute to Arthur rather than to Mordred, for all Arthur’s allies were there. Cuneglas had come from Powys, bringing a dozen lords and his Edling, the Prince Perddel who was now a good-looking boy with his father’s round and earnest face. Agricola, old and stiff-jointed now, accompanied King Meurig, both men in togas. Meurig’s father Tewdric still lived, but the old King had given up his throne, shaved his head into the tonsure of a priest and retired to a monastery in the valley of the Wye where he patiently gathered a library of Christian texts and allowed his pedantic son to rule Gwent in his place. Byrthig, who had succeeded his father as King of Gwynedd, and who now possessed only two teeth, stood fidgeting as though the rituals were a necessary irritant that needed to be finished before he could get back to the waiting mead vats. Oengus Mac Airem, Iseult’s father and the King of Demetia, had come with a party of his dreaded Blackshields, while Lancelot, King of the Belgae, was escorted by a dozen giant men of his Saxon Guard and by the baleful pairs of twins, Dinas and Lavaine and Amhar and Loholt.

Arthur, I noticed, embraced Oengus, who returned the gesture happily. No ill-will there, it seemed, despite Iseult’s awful death. Arthur wore a brown cloak, perhaps not wanting one of his white cloaks to outshine the day’s hero. Guinevere looked splendid in a russet dress that was trimmed with silver and embroidered with her symbol of the moon-crowned stag. Sagramor came in a black gown and had brought his pregnant Saxon wife, Malla, and their two sons. No one came from Kernow. The banners of the Kings, chiefs and Lords were hung from the ramparts where a ring of spearmen, all equipped with newly painted dragon shields, stood guard. A horn sounded again, its noise mournful in the sunny air as twenty other spearmen escorted Mordred towards the stone ring where, fifteen years before, we had first acclaimed him. That first ceremony had been in wintertime and the baby Mordred had been wrapped in fur and carried about the stones in an upturned war shield. Morgan had supervised that first acclamation which had been marked by the sacrifice of a Saxon captive, but this time the ceremony would be an entirely Christian rite. The Christians, I thought grimly, whatever Nimue might think, had won. There were no Druids here except for Dinas and Lavaine and they had no role to play, Merlin was sleeping in Lindinis’s garden, Nimue was on the Tor and no captive would be slaughtered to discover the auguries for the newly acclaimed King’s reign. We had killed a Saxon prisoner at Mordred’s first acclamation, spearing him high in the belly so that his death would be slow and agonizing, and Morgan had watched every painful stagger and every splatter of blood for signs of the future. Those auguries, I remembered, had not been good, though they had promised Mordred a long reign. I tried to remember that poor Saxon’s name, but all I could remember was his terrified face and the fact that I had liked him, and then suddenly his name came winging back across the years. Wlenca! Poor shivering Wlenca. Morgan had insisted on his death, but now, with a crucifix dangling beneath her mask, she was only here as Sansum’s wife and would play no part in the rites.

A muted cheer greeted Mordred’s arrival. The Christians applauded, while we pagans just touched our hands dutifully together and then fell silent. The King was dressed entirely in black: black shirt, black trews, black cloak and a pair of black boots, one of which was monstrously fashioned to encase his clubbed left foot. A gold crucifix hung about his neck and it seemed to me that there was a smirk on his round, ugly face, or perhaps that grimace just betrayed his nervousness. He had kept his beard, but it was a thin thing that did little to improve his bulbous face with its jutting hedges of hair. He walked alone into the royal circle and took his place beside the royal stone.

Sansum, splendid in white and gold, hurried to stand beside the King. The Bishop raised his arms and, without any preamble, began to pray aloud. His voice, always strong, carried right across the huge crowd that pressed behind the Lords, right out to the motionless spearmen on the rampart’s fighting platforms.

‘Lord God!’ he shouted, ‘pour down Thy blessing on this Thy son Mordred, on this blessed King, this light of Britain, this monarch who will lead Thy kingdom of Dumnonia into its new and blessed age.’ I confess I paraphrase the prayer, for in truth I hardly took much notice as Sansum harangued his God. He was good at such harangues, but they were all much alike; always too long, always full of praise for Christianity and always replete with mockery of paganism, so instead of listening I watched the crowd to see who among it spread their arms and closed their eyes. Most did. Arthur, ever ready to show respect to any religion, just stood with head bowed. He held his son’s hand while, on Gwydre’s other side, Guinevere gazed into the sky with a secret smile on her handsome face. Amhar and Loholt, Arthur’s sons by Ailleann, prayed with the Christians, while Dinas and Lavaine just stood, arms folded across their white robes, and stared at Ceinwyn who, just as on that day when she had run from her betrothal, wore neither gold nor silver. Her hair still shone so fine and pale, and she remained for me the loveliest creature that ever walked this earth. Her brother. King Cuneglas, stood on her other side, and catching my eye during one of Sansum’s higher flights of fancy he offered me a wry smile. Mordred, his arms spread in prayer, watched us all with a crooked smile.

When the prayer was done Bishop Sansum took the King’s arm and led him to Arthur who, as the guardian of the kingdom, would now present the new ruler to his people. Arthur smiled at Mordred, as though to give him courage, then led him round the outside of the stone circle and, as Mordred passed, those who were not kings dropped to their knees. I, as his champion, walked behind him with a drawn sword. We walked against the sun, the only time a circle was ever walked thus, to show that our new King was descended from Beli Maw r and could thus defy the natural order of all living things, though Bishop Sansum, of course, declared that the walk against the sun proved the death of pagan superstition. Culhwch, I saw, managed to hide himself during the circle walk so that he would not have to kneel. When two full circles of the stones had been completed Arthur led Mordred to the royal stone and handed him up so that the King stood there alone. Dian, my youngest daughter, then toddled forward with cornflowers woven into her hair and laid a loaf of bread at Mordred’s mismatched feet to symbolize his duty to feed his people. The women murmured at the sight of her, for Dian, like her sisters, had inherited her mother’s careless beauty. She put the loaf down, then looked about her for a sign of what she was supposed to do next and, receiving none, she looked solemnly up into Mordred’s face and immediately burst into tears. The women sighed happily as the child fled crying to her mother and as Ceinwyn scooped her up and dried her tears. Gwydre, Arthur’s son, next carried a leather scourge that he laid at the King’s feet as a symbol of Mordred’s duty to offer the land justice, and then I carried the new royal sword, forged in Gwent and with a hilt of black leather wrapped with golden wire, and gave the sword into Mordred’s right hand. ‘Lord King,’ I said, looking into his eyes, ‘this is for your duty to protect your people.’ Mordred’s smirk had vanished and he stared at me with a cold dignity that made me hope Arthur was right and that the solemnity of this ritual would indeed give Mordred the power to be a good King.

Then, one by one, we presented our gifts. I gave him a fine helmet, trimmed with gold and with a red enamel dragon burned onto its skullpiece. Arthur gave him a scale coat, a spear, and a box of ivory filled with gold coins. Cuneglas offered him ingots of gold from the mines of Powys. Lancelot presented him with a massive cross of gold and a small, gold-framed electrum mirror. Oengus Mac Airem laid two thick bear pelts at his feet, while Sagramor placed a golden Saxon image of a bull’s head on the pile. Sansum presented the King with a piece of the cross on which, he loudly proclaimed, Christ had been crucified. The scrap of dark timber was encased in a Roman glass flask that had been sealed with gold. Only Culhwch presented nothing. Indeed, when the gifts were given and the Lords made a line to kneel before the King and swear their oaths of loyalty, Culhwch was nowhere to be seen. I was the second man to give the oath, following Arthur to the royal stone where I knelt opposite the great heap of shining gold and put my lips to the tip of Mordred’s new sword and swore on my life that I would serve him faithfully. It was a solemn moment, for that was the royal oath, the oath that ruled all others. There was one new thing at that acclamation, a ritual Arthur had devised as a means of continuing the peace he had so carefully constructed and maintained throughout the years. The new ceremony was an extension of his Brotherhood of Britain, for he had persuaded the Kings of Britain - at least those present

- to exchange kisses with Mordred and swear oaths never to fight against each other. Mordred, Meurig, Cuneglas, Byrthig, Oengus and Lancelot all embraced each other, touched their sword blades together and took the oath to keep each other’s peace. Arthur beamed and Oengus Mac Airem, a rogue if ever there was one, gave me a broad wink. Come harvest time, I knew, his spearmen would be raiding Powys’s granaries, whatever oaths he might have sworn.

When the royal oath had been made, I performed the final act of the acclamation. First I gave Mordred my gloved hand and helped him down from the stone and then, when I had conducted him to the northernmost stone of the outer circle, I took his royal sword and laid its bare blade flat on the royal stone. It lay there, glittering, a sword on a stone, the true sign of a King, and then I did the duty of the King’s champion by striding about the circle and spitting at the onlookers and challenging all who listened to dare deny the right of Mordred ap Mordred ap Uther to be the King of this land. I winked at my daughters as I passed, made certain my spittle landed on Sansum’s shining robes, and made equally sure it did not land on Guinevere’s embroidered dress. ‘I declare Mordred ap Mordred ap Uther to be the King!’ I shouted again and again, ‘and if any man denies it, let him fight me now.’ I walked slowly with Hywelbane naked in my hand, and shouted my challenge loud. ‘I declare Mordred ap Mordred ap Uther to be the King, and if any man denies it, let him fight me now.’

I had almost completed the circle when I heard the blade rasp from its scabbard. ‘I deny it!’ A voice shouted and the shout was followed by gasps of horror from the crowd. Ceinwyn blanched, and my daughters, who were already frightened to see me dressed in my unfamiliar iron and steel and leather and wolf-hair, hid their faces in her linen skirt.

I turned slowly and saw that Culhwch had come back to the circle and now faced me with his big battle sword drawn. ‘No,’ I called to him, ‘please.’

Culhwch, grim-faced, strode to the circle’s centre and plucked the King’s gold-hilted sword from the stone. ‘I deny Mordred ap Mordred ap Uther,’ Culhwch said ceremoniously, then threw the royal blade down onto the grass.

‘Kill him,’ Mordred shouted from his place beside Arthur. ‘Do your duty, Lord Derfel!’

‘I deny his fitness to rule!’ Culhwch shouted at the assembly. A wind lifted the banners on the walls and stirred Ceinwyn’s golden hair.

‘I order you to kill him!’ Mordred shouted excitedly.

I walked into the circle to face Culhwch. My duty now was to fight him, and if he killed me then another King’s champion would be selected and so the stupid business would go on until Culhwch, battered and bloody, lay twitching his life blood into Caer Cadarn’s soil, or, more likely, till a full-scale battle erupted on the summit that would end with either Culhwch’s or Mordred’s party triumphant. I pulled the helmet off my head, shook the hair out of my eyes and hung the helmet over the throat of my scabbard. Then, with Hywelbane still in my hand, I embraced Culhwch. ‘Don’t do this,’ I whispered in his ear. ‘I can’t kill you, my friend, so you will just have to kill me.’

‘He’s a bastard little toad, a worm, not a King,’ he murmured.

‘Please,’ I said. ‘I cannot kill you. You know that.’

He hugged me tight. ‘Make peace with Arthur, my friend,’ he whispered, then he stepped away and rammed his sword back into its scabbard. He picked Mordred’s sword out of the grass, gave the King a sour look, then laid the blade back on the stone, ‘I yield the fight,’ he called so that all on the summit could hear him, then he crossed to Cuneglas and knelt at his feet. ‘Will you have my oath, Lord King?’

It was an embarrassing moment, for if the King of Powys accepted Culhwch’s loyalty then Powys’s first act of this new Dumnonian reign was to welcome an enemy of Mordred’s, but Cuneglas did not hesitate. He pushed his sword hilt forward for Culhwch’s kiss. ‘Gladly, Lord Culhwch,’ he said, ‘gladly.’

Culhwch kissed Cuneglas’s sword, then rose and walked to the west gate. His spearmen followed him and thus, with Culhwch’s going, Mordred at last had the kingdom’s power unchallenged. There was silence, then Sansum began to cheer and the Christians followed his lead and so acclaimed their new ruler. Men gathered about the King, calling their congratulations, and I saw that Arthur was left to one side, alone. He looked at me and smiled, but I turned away. I sheathed Hywelbane, then crouched by my still frightened daughters and told them there was nothing to be worried about. I gave Morwenna my helmet to hold, and showed her how the cheek pieces swung back and forward on their hinges. ‘Don’t break it!’ I warned her.

‘Poor wolf,’ Seren said, stroking the wolf-tail.

‘It killed a lot of lambs.’

‘Is that why you killed the wolf?’

‘Of course.’

‘Lord Derfel!’ Mordred’s voice suddenly called, and I straightened and turned round to see that the King had shaken off his admirers and was limping across the royal circle towards me. I walked to meet him, then bowed my head. ‘Lord King.’

The Christians gathered behind Mordred. They were the masters now, and their victory was plain on their faces. ‘You swore an oath, Lord Derfel,’ Mordred said, ‘to obey me.’

‘I did, Lord King.’

‘But Culhwch still lives,’ he said in a puzzled voice. ‘Does he not still live?’

‘He lives, Lord King,’ I said.

Mordred smiled. ‘A broken oath, Lord Derfel, deserves punishment. Isn’t that what you always taught me?’

‘Yes, Lord King.’

‘And the oath, Lord Derfel, was sworn on your life, was it not?’

‘Yes, Lord King.’

He scratched at his thin beard. ‘But your daughters are pretty Derfel, so I would be sorry to lose you from Dumnonia. I forgive you that Culhwch still lives.’

‘Thank you, Lord King,’ I said, fighting back a temptation to hit him.

‘But a broken oath still deserves punishment,’ he said excitedly.

‘Yes, Lord King,’ I agreed. ‘It does.’

He paused a heartbeat, then struck me hard across the face with the leather flail of justice. He laughed, and was so delighted with the surprised reaction on my face that he hit me with the flail a second time.

‘Punishment given, Lord Derfel,’ he said, then turned away. His supporters laughed and applauded. We did not stay for the feast, nor for the wrestling matches and the mock bouts of swordplay and the displays of juggling, nor for the tame dancing bear and the competition of the bards. We walked, a family, back to Lindinis. We walked beside the stream where the willows grew and the purple loosestrife flowered. We walked home.

Cuneglas followed us within the hour. He planned to stay with us for one week, then he would go back to Powys. ‘Come back with me,’ he said.

‘I’m sworn to Mordred, Lord King.’

‘Oh, Derfel, Derfel!’ He put his arm around my neck and walked up the outer courtyard with me. ‘My dear Derfel, you’re as bad as Arthur! You think Mordred cares if you keep your oath?’

‘I hope he doesn’t want me as an enemy.’

‘Who knows what he wants?’ Cuneglas asked. ‘Girls, probably, and fast horses and running deer and strong mead. Come home, Derfel! Culhwch will be there.’

‘I shall miss him, Lord,’ I said. I had hoped that Culhwch would be waiting at Lindinis when we returned from Caer Cadarn, but he had plainly not dared waste a moment and was already racing north to escape the spearmen who would be sent to find him before he crossed the frontier. Cuneglas abandoned his attempt to persuade me north. ‘What was that rogue Oengus doing there?’

he asked me peevishly. ‘And making that promise to keep the peace too!’

‘He knows, Lord King,’ I said, ‘that if he loses Arthur’s friendship then your spears will invade his land.’

‘He’s right,’ Cuneglas said grimly. ‘Maybe I’ll give that job to Culhwch. Will Arthur have any power now?’

‘That depends on Mordred.’

‘Let’s assume Mordred isn’t a complete fool. I can’t comprehend Dumnonia without Arthur.’ He turned as a shout from the gate announced more visitors. I half expected to see dragon shields and a party of Mordred’s men searching for Culhwch, but instead it was Arthur and Oengus Mac Airem who had arrived with a score of spearmen. Arthur hesitated at the gate’s threshold. ‘Am I welcome?’ he called to me.

‘Of course, Lord,’ I replied, though not warmly.

My daughters spied him from a window and a moment later they ran shrieking to welcome him. Cuneglas joined them, pointedly ignoring King Oengus Mac Airem who crossed to my side. I bowed, but Oengus pushed me upright and enfolded me in his arms. His fur collar stank of sweat and old grease. He grinned at me. ‘Arthur tells me you haven’t fought a decent war in ten years,’ he said.

‘It must be that long, Lord.’

‘You’ll be out of practice, Derfel. First proper fight and some slip of a boy will rip your belly out to feed his hounds. How are you?’

‘Older than I was, Lord. But well. And you?’

‘I’m still alive,’ he said, then glanced back at Cuneglas. ‘I assume the King of Powys doesn’t want to greet me?’

‘He feels, Lord King, that your spearmen are too busy on his frontier.’

Oengus laughed. ‘Have to keep them busy, Derfel, you know that. Idle spearmen are trouble. And besides, I’ve got too many of the bastards these days. Ireland’s going Christian!’ he spat. ‘Some interfering Briton called Padraig turned them into milksops. You never dared conquer us with your spears so you sent that piece of seal shit to weaken us, and any Irishman with proper guts is coming to the Irish kingdoms in Britain to escape his Christians. He preached to them with a clover leaf! Can you imagine that? Conquering Ireland with a clover leaf? No wonder all the decent warriors are coming to me, but what can I do with them?’

‘Send them to kill Padraig?’ I suggested.

‘He’s dead already, Derfel, but his followers are all too much alive.’ Oengus had drawn me into a corner of the courtyard where he stopped and looked up into my face. ‘I hear you tried to protect my daughter.’

‘I did, Lord,’ I said. I saw that Ceinwyn had come from the palace and was embracing Arthur. They held each other as they talked and as Ceinwyn glanced reprovingly towards me. I turned back to Oengus. ‘I drew a sword for her, Lord King.’

‘Good of you, Derfel,’ he said carelessly, ‘good of you, but it isn’t important. I’ve several daughters. Not even sure I can remember which one Iseult was. Skinny little thing, yes?’

‘A beautiful girl, Lord King.’

He laughed. ‘Anything young with tits is beautiful when you’re old. I do have one beauty in the brood. Argante, she’s called, and she’ll break a few hearts before her life’s done. Your new King will be looking for a bride, won’t he?’

‘I suppose so.’

‘Argante would do for him,’ Oengus said. He was not being kind to Mordred by suggesting his beautiful daughter as Dumnonia’s Queen, but rather making sure that Dumnonia would go on protecting Demetia from the men of Powys. ‘Maybe I’ll bring Argante on a visit here,’ he said. Then he abandoned the subject of that possible marriage and shoved a scarred fist hard into my chest. ‘Listen, my friend,’ he said forcefully, ‘it isn’t worth falling out with Arthur over Iseult.’

‘Is that why he brought you here, Lord?’ I asked suspiciously.

‘Of course it is, you fool!’ Oengus said happily. ‘And because I can’t stand all those Christians on the Caer. Make your peace, Derfel. Britain isn’t so big that decent men can start spitting at each other. I hear Merlin lives here?’

‘You’ll find him through there,’ I said, pointing towards an arch that led to a garden where Ceinwyn’s roses blossomed, ‘what’s left of him.’

‘I’ll go and kick some life into the bastard. Maybe he can tell me what’s so special about a clover leaf. And I need a charm to help me make new daughters.’ He laughed and walked away. ‘Getting old, Derfel, getting old!’

Arthur gave my three daughters into the keeping of Ceinwyn and their Uncle Cuneglas, then walked towards me. I hesitated, then gestured through the outer gate and walked ahead of him into the meadows where I waited and stared at Caer Cadarn’s banner-hung ramparts above the intervening trees. He stopped behind me. ‘It was at Mordred’s first acclamation,’ he said softly, ‘that you and I first met Tristan. Do you remember?’

I did not turn round. ‘Yes. Lord.’

‘I am no longer your lord, Derfel,’ he said. ‘Our oath to Uther is done, it’s finished. I am not your lord, but I would be your friend.’ He hesitated. ‘And for what happened,’ he went on, ‘I am sorry.’

I still did not turn round. Not out of pride, but because there were tears in my eyes. ‘I am sorry too,’ I said.

‘Will you forgive me?’ he asked humbly. ‘Will we be friends?’

I stared at the Caer and thought of all the things I had done that needed forgiveness. I thought of the bodies on the moor. I had been a young spearman then, but youth was no excuse for slaughter. It was not up to me, I thought, to forgive Arthur for what he had done. He had to do that for himself. ‘We shall be friends,’ I said, ‘till death.’ And then I turned.

And we embraced. Our oath to Uther was done. And Mordred was King.
