‘How did Merlin get inside?’ Arthur asked.
I made a guess. ‘The far side, Lord.’ The temple was on the eastern side of the fire-maze and I suspected a passage must surely have been left through the outer spirals. Arthur hauled on his rein and urged Llamrei up the slope of the inner rampart to the path that ran along its crest. The Blackshields scattered rather than face him. We rode up the rampart after Arthur, and though our horses were terrified of the great fire to their right, they followed Llamrei through the whirling sparks and smoke. Once a great section of fire collapsed as we galloped past and my horse swerved away from the inferno onto the outer face of the inner rampart. For a second I thought she was going to tumble down into the ditch and I was hanging desperately out of the saddle with my left hand tangled in her mane, but somehow she found her footing, regained the path and galloped on. Once past the northern tip of the great fire rings Arthur turned down onto the summit plateau again. A glowing ember had landed on his white cloak and started the wool smouldering, and I rode alongside him and beat the small fire out. ‘Where?’ he called to me.
‘There, Lord,’ I pointed to the spirals of fire nearest to the temple. I could see no gap there, but as we drew closer it was apparent that there had been a gap which had been closed with firewood, though that new wood was not nearly so thickly stacked as the rest and there was a narrow space where the fire, rather than being eight or ten feet tall, was no higher than a man’s waist. Beyond that low gap lay the open space between the outer and inner spirals, and in that space we could see more Blackshields waiting.
Arthur walked Llamrei towards the gap. He was leaning forward, speaking to the horse, almost as if he was explaining to her what he wanted. She was frightened. Her ears kept pricking back, and she took short nervous steps, but she did not shy from the raging fires that burned on either side of the only passage into the heart of the hilltop fire. Arthur stopped her a few paces short of the gap and calmed her, though her head kept tossing and her eyes were wide and white. He let her look at the gap, then he patted her neck, spoke to her again, and wheeled away.
He trotted in a wide circle, spurred her ii\to a canter, then spurred her again as he aimed at the gap. She tossed her head and I thought she would baulk, but then she seemed to make up her mind and flew at the flames. Cuneglas and Galahad followed. Culhwch cursed at the risk we were taking, then all of us kicked our horses in Llamrei’s wake.
Arthur crouched over the mare’s neck as she pounded towards the fire. He was letting Llamrei choose her pace and she slowed again. I thought she would shy away, then I saw she was gathering herself for the leap between the flames. I was shouting, trying to cover my fear, then Llamrei jumped and I lost sight of her as the wind snatched a cloak of flaming smoke over the gap. Galahad was next into the space, but Cuneglas’s horse swerved away. I was galloping hard behind Culhwch, and the heat and clamour of the fires was filling the noisy air. I think I half wanted my horse to refuse, but she kept on and I closed my eyes as the flame and smoke surrounded me. I felt the horse rise, heard her whinny, then we thumped down inside the outer ring of flame and I felt a vast relief and wanted to shout in triumph. Then a spear ripped into my cloak just behind my shoulder. I had been so intent on surviving the fire that I had not thought about what waited for us inside the flame ring. A Blackshield had lunged at me and had missed, but now he abandoned the spear and ran to pull me from the saddle. He was too close for my own spear blade to be of use so I simply rammed the staff down at his head and kicked my horse on. The man seized my spear. I let it go, drew Hywelbane and hacked back once. I glimpsed Arthur circling on Llamrei and flailing left and right with his sword, and now I did the same. Galahad kicked a man in the face, speared another, then spurred away. Culhwch had seized a Blackshield’s helmet crest and was dragging the man towards the fire. The man tried desperately to untie the chin strap, then screamed as Culhwch hurled him at the flames before wheeling away.
Issa was through the gap now, and so were Cuneglas and his six followers. The surviving Blackshields had fled towards the centre of the maze of fire and we followed them, trotting between two leaping walls of flame. The borrowed sword in Arthur’s hand was red with light. He kicked Llamrei and she began to canter and the Blackshields, knowing they must be caught, ran aside and dropped their spears to show they would fight no more.
We had to ride halfway around the circle to find the entrance to the inner spiral. The gap between the inner and outer fires was a good thirty paces across, wide enough to let us ride without being roasted alive, but the space inside the spiral’s passage was less than ten paces in width, and these were the biggest fires, the fiercest, and we all hesitated at the entrance. We could still see nothing of what happened within the circle. Did Merlin know we were here? Did the Gods? I looked up, half expecting a vengeful spear to hurtle down from heaven, but there was only the twisting canopy of smoke shrouding the fire-tortured, light-cascading sky.
And so we rode into the last spiral. We rode hard and fast, galloping in a tightening curve between the roaring blast of leaping flames. Our nostrils filled with smoke as embers scorched our faces, but turn by turn we drew ever nearer to the mystery’s centre.
The noise of the fires obscured our coming. I think that Merlin and Nimue had no idea that their ritual was about to be ended for they did not see us. Instead the guards at the circle’s centre saw us first and they shouted in warning and ran to oppose us, but Arthur came out of the fires like a demon cloaked in smoke. Indeed, his clothes streamed smoke as he shouted a challenge and rammed Llamrei hard into the Blackshields’ hasty, half-formed shield wall. He broke that wall by sheer speed and weight, and the rest of us followed, swords swinging, while the handful of loyal Blackshields scattered. Gwydre was there. And Gwydre lived.
He was in the grip of two Blackshields who, seeing Arthur, let the boy go free. Nimue screamed at us, winging curses across the central ring of five fires as Gwydre ran sobbing to his father’s side. Arthur leaned down and with a strong arm lifted his son onto the saddle. Then he turned to look at Merlin. Merlin, his face streaming with sweat, gazed calmly at us. He was halfway up a ladder that was leaning against a gallows made of two tree trunks struck upright in the ground and crossed by a third, and that gallows now stood in the very centre of the five fires that formed the middle ring. The Druid was in a white robe and the sleeves of that robe were red with blood from their cuffs to the elbow. In his hand was a long knife, but on his face, I swear, there was a momentary look of utter relief. The boy Mardoc lived, though he would not have lived for long. The child was already naked, all but for a strip of cloth that had been tied about his mouth to silence his screams, and he was hanging from the gallows by his ankles. Next to him, also hanging by the ankles, was a pale, thin body that looked very white in the flamelight, except that the corpse’s throat had been cut almost to the spine and all the man’s blood had run down into the Cauldron, and still it ran to drip from the lank, reddened ends of Gawain’s long hair. The hair was so long that its gory tresses fell inside the golden rim of the silver Cauldron of Clyddno Eiddyn, and it was only by that long hair that I knew it was Gawain who hung there, for his handsome face was sheeted with blood, hidden by blood, cloaked in blood. Merlin, still with the long knife that had killed Gawain in his hand, seemed dumbstruck by our coming. His look of relief had vanished and now I could not read his face at all, but Nimue was shrieking at us. She held up her left palm, the one with the scar that was the twin of the scar on my left palm. ‘Kill Arthur!’ she shouted at me. ‘Derfel! You are my sworn man! Kill him! We can’t stop now!’
