‘Can’t reach it,’ she muttered.

‘See that long spear of glass, there? Reach under and hook it through the strap of the pack and drag it out.’

‘It’ll cut me.’

‘Wrap your shirt around your hand or something. Don’t you have any initiative?’

It was the wrong thing to say. Ullii simply closed her eyes and scrunched herself up in the corner.

‘Ullii?’

She blocked him out.

He was quiet for a while, and then he said, ‘If I die, you’ll be all alone up here.’

‘I can climb out.’

‘Down to Ghorr and the scrutators?’

She scrunched herself up into a tighter ball. ‘You can’t help me, Nish.’

‘I wasn’t planning to. Ullii, I’ve been a fool. I treated you badly, and hurt you terribly. I’ve done stupid things and I’m sorry for them …’

‘Yes?’ she said when he did not go on. She liked hearing him talk like that.

‘I have to do something good to make up for it …’

She didn’t reply at once. Ullii was no fool – he was trying to lead her somewhere and she didn’t want to follow. But neither did she want to be alone again.

‘What, Nish?’

‘You’ve done wrong too, Ullii. You betrayed your friends. You’ve condemned Flydd and Irisis, and everyone else in Fiz Gorgo.’

‘It wasn’t my fault. Ghorr made me do it.’

‘No, Ullii. You chose to help Ghorr.’

‘He forced me.’

‘You didn’t have to find this place. You could have told him that you couldn’t see anyone in your lattice.’

‘He was too strong. He was going to hurt me!’

‘You could have resisted.’

‘He threatened me with Scrutator Fusshte. He’s the most evil scrutator of all, Nish.’

‘You could have resisted even Fusshte,’ Nish said inexorably. ‘You could have pretended that you’d lost the lattice. They wouldn’t have known any different.’

‘It was as if Fusshte was looking at me though my clothes; even through my skin.’

‘I’m sure that was horrible, but you betrayed your friends and now they’re all going to be put to death in the most awful way. Once the scrutators have killed them, the last hope of the world will be gone. We’ll lose the war and the lyrinx will eat us all, even you, Ullii. And it’ll all be your fault.’

‘No,’ she said in an almost inaudible squeak. ‘No, no, no!’

‘Yes,’ Nish said.

Ullii couldn’t make herself any smaller or any more insignificant. She couldn’t close down her senses to keep him at bay and she couldn’t escape. She had no choice but to take in what he was saying, though she knew he was manipulating her.

She had betrayed her friends and, for the first time, Ullii had to face up to it. She’d known it all along, but had put it out of mind – even those awful sounds as the guards on the wall had been slain without warning.

And how many people were yet to die? Dozens stood in the yard, waiting in the freezing cold for their doom. She looked out the embrasure. The vast rope-and-canvas platform would soon be finished. Two prisoners were being hauled up in a rope net, their arms and legs dangling out through the mesh.

She heard a faint, mournful wail – a young woman’s cry of soul-rending anguish. It wasn’t Irisis, for she would never have given way like that. Was it little Inouye? Was she wailing because she would never see her babies again, or because she knew that even they would suffer for the crime she’d been accused of?

Nish stood up, still holding his thumb over the gash, and looked over her shoulder. ‘It’s nearly midday. The trials will begin as soon as the last prisoners are lifted up to the amphitheatre, and Ghorr will want it well over before dark. He won’t dare stay here after the sun goes down. Air-dreadnoughts are too vulnerable to flying lyrinx.’

His nearness made her uncomfortable, though the scent of him had always calmed her. Ullii tried to rouse her previous fury by thinking about all the things Nish had done to her, but at the look in his eyes, so familiar, so guilty, so vulnerable, she could not. Violence was simply not in her nature. What would be the point, anyway? Myllii and Yllii couldn’t be brought back and the sooner she joined them the better. ‘What do you want from me, Nish?’

‘I want you to help me. We’ve got to try and save them.’

‘They have hundreds of guards,’ she said dully. ‘And dozens of mancers watching over them. I can’t do anything and neither can you.’

‘We have to try.’

‘I’m too scared.’

‘I’m scared too. But look – we’ve both done wrong, Ullii, and this is the only way we can make up for it. We have to atone for what we’ve done.’

FIVE

The operation on his forearm was more painful than it should have been, because Ullii couldn’t bear to look at the gash and insisted on sewing him up with her eyes closed. Each time the bloody needle, trailing its red threads, came at him he flinched and Ullii jumped, then forced it through his skin and flesh as if to cause the maximum of discomfort. Nish gritted his teeth and restrained himself from crying out, though it wasn’t possible to remain silent when she roughly pulled the sides of the gash together and tied the threads.

‘Thank you,’ he said once it had been done and bound with the tail of a spare shirt from her pack. ‘Now we’d better find a way out of here.’

Nish knew it was hopeless. Ullii was too timid; if he’d had his choice of all the co-conspirators in the world, he couldn’t have found someone with less initiative.

He looked out the window and blanched. How had she climbed the tower without ropes or irons? It was beyond him and that wasn’t cowardice. Nish simply didn’t have the skills to climb down that sheer face. If he tried, he’d certainly fall to his death.

The rubble blocking the stair was still too hot to approach. The rods that supported and tensioned the roof were immovable; he’d tried them earlier.

‘Ullii, you’ll have to climb down and find some rope. I can’t get out any other way.’

‘Rope?’ she said, as if she’d never heard of such a thing. ‘I don’t know where there’s any rope.’

He thought for a moment. ‘Do you know where the front door of Fiz Gorgo is?’

‘Yes. I went through it with Ghorr.’

‘If you can climb down –’

‘Of course I can climb down,’ she said, tossing her head.

‘Then go out into the yard. It’s empty now, but be careful. Ghorr might have guards posted. Around to the left, near the wall, there’s a little stone shed that Inouye uses – she’s the air-floater pilot. The innocent one whose little children are going to be murdered,’ he said deliberately. ‘The door won’t be locked, and you’ll find coils of rope in there. Can you bring one back? And make sure it’s long enough …’ He gauged the distance down to the roof. ‘You’ll need about eight or nine spans. Do you know how much a span is?’

She gave him one of her famous looks and climbed out the embrasure on the side away from the yard. Nish watched her go down, amazed at how easy she made it look, and even more amazed that such a timid person could do it at all. But then, Ullii could be surprisingly competent when she had no choice in the matter.

He glanced up. The amphitheatre looked almost complete now. The ropers, who earlier had been swarming like sailors in the rigging of a merchant vessel, were gone apart from a few above a tower on the other side of Fiz Gorgo, who were tensioning lines with a complicated array of pulleys. He couldn’t see what was going on above the deck.

Nish looked further up, to the nearest of the air-dreadnoughts, but immediately jerked his head below the sill of the embrasure. For a moment he’d thought the grey robed mancer had been staring straight at him. He took another peep. The brass spyglass was not pointed his way at all, but at the horned tower to his left. It had also been struck by that initial blast, but whatever the strange energies or magics inside, they had not been completely liberated. The tower was sagging more than this one and glowing redly three floors below the roof. Bladder-like extrusions of molten material were being forced out of the slit embrasures. One burst, filling the air with shards of brown glass which set instantly, glittering in a momentary ray of sunlight, before tinkling to the paving stones of the yard.
