Suth pushed him gently away and looked at him. 'Why are you here?'

Carnelian's head throbbed. He reached up to feel for the spike hammering into it. 'My heart,' he said, not understanding how this could rhythm his father's words.

His father frowned, looked puzzled. He turned his head to one side, listening. 'No, not your heart, the God Emperor's.' His face darkened. 'Why are you here, my Lord?'

'I came to…' He saw the Ruling Ring on his father's finger and pointed. 'Good, they gave it to you.'

His father looked at his ring, frowning. He rubbed his finger over its cypher and showed Carnelian the ink stain on his skin. Carnelian felt that his father's eyes were seeing into his head. This is not the time to examine what has transpired in the coomb, but be assured, my Lord, that you will have to provide me with a full account. Now, why did you come?'

The ache in Carnelian's head made it difficult to think. 'Your letter-'

'Contained nothing about your coming here.'

Carnelian began shaking his head but stopped when it increased the hammering.

The look in his father's eyes softened. 'You are in pain, my son?'

'Just an ache… The letter you sent purported to be from you but was written in another's hand.'

'I should have explained that in the letter. The drugs the Wise have been giving me-'

'Your wound, Father!' Carnelian felt sick that he had forgotten it.

'Do not concern yourself. Under their supervision it heals well enough.' Suth rifted trembling hands. 'But you see how it affects me?' Carnelian stared at his father's hands. They looked so frail. His father rested them on his knees. 'What did you hope to achieve by coming here?'

To discover if you were still alive. To make sure that Aurum was not using your…'

'… corpse?' His father snorted a smile. Then his face hardened again. 'What part has Jaspar played in this?'

'How do you-? Of course, his people outside. Are they suffering like me?'

His father made a dismissive gesture. 'Not as much as you. Why are they here?'

Carnelian grimaced. 'It was the only way I could think of getting to court.'

His father's eyes narrowed. 'Who put this idea in your head?'

Carnelian considered it. ‘Spinel, I suppose.' 'Did he indeed. Was it also his idea for you not to come as yourself?'

Carnelian nodded.

His father rolled his eyes. 'What price did Jaspar ask for aiding you in this farce?' 'None.'

'Do you really believe the Lord Jaspar would do this from kindness?'

'His father's murder made him my natural ally.' 'What do you mean?' 'Ykoriana murdered his fath-'

Suth slapped his hand over Carnelian's mouth. 'You must not make such accusations,' he hissed. 'Here, you must take care even when speaking that name.' He looked round as if there might have been ears lurking in the shadows. 'We are in the very heart of her power.'

'Still. You can see what I mean, Father?'

'What you suggest is utterly impossible.' 'Ammonites…'

'No. The Wise would never conspire with her to give her the leverage to topple the Balance.'

'Surely you could not imagine that any of Jaspar's household would have dared such an act?'

His father shook his head. There is another suspect.'

'An enemy among the Great?'

'Someone much closer to home.'

Carnelian thought it through. His jaw dropped. 'His own father …'

Suth nodded slowly, giving his son time to let it sink in. 'While we were crossing the sea, she gained control of Imago, and with him their faction.'

'But to kill his own father… surely he will be punished.'

Suth made a sign of doubt. 'If there were proof, the Wise and the Clave together would send him for ever into the outer world… but he will have left no proof.'

Carnelian saw again the crucifixion. 'Even now he washes away his guilt with their blood.' Carnelian shook his eyes free of the nightmare and looked at his father. 'Why did he bring me, then? To curry favour with you?'

'No, to make me vulnerable through you.'

Carnelian sagged and his head felt close to exploding. Then I must return immediately to the coomb.'

That would change nothing. The damage is done, but perhaps we can still turn this to our advantage. Whether you stay or go you must remain here at least until you have recovered from the sky sickness.'

'Jaspar did warn me but I chose not to listen.'

His father smiled. 'It is better to be free of him. Besides, by tomorrow it will have gone.' As he stood up,

Carnelian noticed that he was clutching his side. Suth caught his look. 'It spasms sometimes, that is all.'

Carnelian reached up to touch his father's arm. 'I would rather stay.'

'We would hardly see each other. The machinations of the election are interminable and alas, I am at their centre.'

'I would find ways to amuse myself.' That is what I am afraid of,' his father said through a crooked grin.

Carnelian did not recognize the mask his father put up to hide his face. Its right eye sprayed sun rays over the cheek and forehead. Wearing it, his father could have been an angel peering down indulgently upon the little world of men.

'I shall dismiss Jaspar's men and leave some of my Ichorians to make sure you are not disturbed. They will attend to you. In their presence you may remain unmasked. While I am He-who-goes-before they perform the function of our tyadra. Please, do not leave this chamber until either I come myself or send a summons. Will you do that for me, my son?'

Carnelian nodded, smiling, but his smile crumbled as he watched his father's painful walk across the floor. Turquoises and iridescent blues streaked across the opening door. For a moment Carnelian glimpsed the two half-black men standing guard outside wearing the lictors' golden fish-scales, then the door closed. As he lay back, it felt as if his head were being nailed to the bed.

Carnelian found that if he paced about, the pain in his head became more bearable. The shutters drew him with their fevered shaking. He ran his fingers up the bright crack where they met. The smooth wood led his touch up to a cold mechanism. Bringing his fingertips to his nose, he could smell bronze. He brought a lamp to see the handles, then yanked them down. The lock clicked and the shutters slapped against his hands. As he opened his arms, air and light broke over him like a wave. For moments he was blind and blinking but then a round shape formed in the glare: the Plain of Thrones. Beyond lay the Skymere's fading blue. The looser curve of the Sacred Wall hardened up from its edge. Over it, the Guarded Land was a patchy lilac layer squeezing away under a colourless sky. He was so high that he imagined his outstretched arms were wings lifting him soaring above the crater of Osrakum.

Next day, Carnelian was fretting. He had thrown the last of the sickness off as he slept. With his vigour fully returned, he regretted the promise he had made his father. The chamber felt like a cage. He climbed out of bed and was putting more wood on the fire when there was a knocking at the door. Eagerly he grabbed his mask, hid his face and bade whoever was outside to enter.

A two-headed monster came into the chamber. Carnelian backed away, looking round for something to use as a weapon. The monster kneeled on its three legs and bowed its heads. 'Seraph,' two voices chorused in Quya.

Carnelian pressed his mask to his face to see the creature better through the eyeslits. His head jerked up as another of the creatures came into the chamber. This was four-legged and its two abdomens each had its own head. It was carrying a long box with the outermost of its four arms.

'Seraph?' said the monster still kneeling in front of him.

Carnelian looked down. It was offering him a letter in its tattooed hand. He reached behind his head to tie on his mask and then he took the letter gingerly, as if the hand offering it were fanged. Keeping an eye on the creature he turned the letter and saw that it was sealed with his father's Ruling Ring. He broke it open and read:
