'Let's keep on.' Ninefingers scratched at his face and stared round anxiously. 'Let's leave this place as quickly as we can, and never come back.'

Bayaz chuckled. 'The Bloody-Nine, scared of shadows? I'd never have believed it.'

'Every shadow's cast by something,' growled the Northman, but the First of the Magi was not to be put off.

'We have time enough to stop,' he said as he struggled from the saddle. 'We are close to the edge of the city, now. An hour at the most and we are out and on our way. You might find this interesting, Captain Luthar. As would anyone else who would care to join me.'

Ninefingers cursed under his breath in his own tongue. 'Alright, then. I'd rather walk than wait.'

'You have quite piqued my curiosity,' said Brother Longfoot as he jumped down next to them. 'I must confess that the city does not seem so daunting in the light as it did in the rain of yesterday. Indeed, it is hard now to see why it has such a black reputation. Nowhere in all the Circle of the World can there be such a collection of fascinating relics, and I am a curious man, and unashamed to admit it. Yes indeed, I have always been a-'

'We know what you are,' hissed Ferro. 'I'll wait here.'

'Please yourself.' Bayaz dragged his staff from his saddle. 'As always. You and Master Quai can no doubt each delight the other with comical tales while we are gone. I am almost sorry to miss the banter.' Ferro and the apprentice frowned at each other as the rest of them made their way between the ruined statues and up the wide steps, Jezal limping and wincing on his bad leg. They passed through a doorway as big as a house and into a cool, dim, silent space.

It reminded Jezal of the Lords' Round in Adua, but even bigger. A cavernous, circular chamber, like a great bowl with stepped seating up the sides, carved from stone of many colours, whole sections of it smashed and ruined. The bottom was choked with rubble, no doubt the remnants of a collapsed roof.

'Ah. The great dome fallen.' The Magus squinted up through the ragged space into the bright sky beyond. 'A fitting metaphor.' He sighed, shuffling slowly round the curving aisle between the marble shelves. Jezal frowned up at that vast weight of overhanging stone, wondering what might happen if a chunk of it should fall and hit him on the head. He doubted Ferro would be stitching that up. He had not the slightest idea why Bayaz wanted him here, but then he could have said that for the whole journey, and indeed he often had. So he took a deep breath and limped out after the Magus, Ninefingers just behind, the noises of their movement echoing around in the great space.

Longfoot picked his way among the broken steps and peered up at the fallen ceiling with a show of great interest. 'What was this place?' he called out, voice bouncing from the curved walls. 'Some manner of theatre?'

'In a sense,' replied Bayaz. 'This was the great chamber of the Imperial Senate. Here the Emperor sat in state, to hear debates between the wisest citizens of Aulcus. Here decisions were made that have set the course of history.' He clambered up a step and shuffled further, pointed excitedly to the floor, voice shrill with excitement.

'It was on this precise spot, as I remember it, that Calica stood to address the senate, urging caution in the Empire's eastern expansion. It was down there that Juvens replied to him, arguing boldness, and carried the day. I watched them, spellbound. Twenty years old, and breathless with excitement. I still recall their arguments, in every detail. Words, my friends. There can be a greater power in words than in all the steel within the Circle of the World.'

'A blade in your ear still hurts more than a word in it, though,' whispered Logen. Jezal spluttered with laughter, but Bayaz did not seem to notice. He was too busy hurrying from one stone bench to another.

'Here Scarpius gave his exhortation on the dangers of decadence, on the true meaning of citizenship. The senate sat, entranced. His voice rang out like . . . like . . .' Bayaz plucked at the air with his hand, as though hoping to find the right word there. 'Bah. What does it matter now? There are no certainties left in the world. That was the age of great men, doing what was right.' He frowned down at the broken rubble choking the floor of the colossal room. 'This is the age of little men, doing what they must. Little men, with little dreams, walking in giant footsteps. Still, you can see it was a grand building once!'

'Er, yes . . .' ventured Jezal, limping away from the others to peer at some friezes carved into the wall at the very back of the seating. Half-naked warriors, awkwardly posed, pushing at each other with spears. All grand, no doubt, but there was an unpleasant smell to the place. Like rot, like damp, like sweating animals. The odour of a badly cleaned stables. He peered into the shadows, wrinkling his nose. 'What is that smell?'

Ninefingers sniffed the air, and his face fell in an instant. A picture of wide-eyed horror. 'By the . . .' He ripped his sword out, taking a step forward. Jezal turned, fumbling for the grips of his steels, a sudden fear pressing on his chest . . .

He took it at first for some manner of beggar: a dark shape, swathed in rags, squatting on all fours in the darkness only a few paces away. Then he saw the hands; twisted and claw-like on the pitted stone. Then he saw the grey face, if you could call it a face; a chunk of hairless brow, a lumpen jaw bursting with outsize teeth, a flat snout like a pig's, tiny black eyes glinting with fury as it glared back at him. Something between a man and an animal, and more hideous by far than either. Jezal's jaw dropped open, and he stood gawping. It scarcely seemed worth telling Ninefingers that he now believed him.

It was clear there were such things as Shanka in the world.

'Get it!' roared the Northman, scrambling up the steps of the great chamber, drawn sword in hand. 'Kill it!'

Jezal shambled uncertainly towards the thing, but his leg was still halfway to useless and the creature was quick as a fox, turning and skittering across the cold stone towards a crack in the curving wall and wriggling through like a cat through a fence before he had got more than a few lurching steps.

'It's gone!'

Bayaz was already shuffling towards the entrance, the tapping of his staff on the marble echoing above them. 'We see that, Master Luthar. We all very clearly see that!'

'There'll be more,' hissed Logen, 'there're always more! We have to go!'

It had been bad luck, Jezal thought as he lurched back towards the entrance, stumbling down the broken steps and wincing at the pain in his knee. Bad luck that Bayaz had decided to stop, right here and now. Bad luck that Jezal's leg had been broken and he couldn't run after that repulsive thing. Bad luck that they had come to Aulcus, instead of being able to cross the river miles downstream.

'How did they get here?' Logen was shouting at Bayaz.

'I can only guess,' grunted the Magus, wincing and breathing hard. 'After the Maker's death we hunted them. We drove them into the dark corners of the world.'

'There are few corners darker than this one.' Longfoot hurried past them for the entrance and down the steps, two at a time, and Jezal hopped after him.

'What is it?' called Ferro, pulling her bow off her shoulder.

'Flatheads!' roared Ninefingers.

She gazed at him blankly and the Northman flapped his free hand at her. 'Just fucking ride!'

Bad luck. That Jezal had beaten Bremer dan Gorst and been chosen by Bayaz for this mad journey. Bad luck that he had ever held a fencing steel. Bad luck that his father had wanted him to join the army instead of doing nothing with his life like his two brothers. Strange how that had always seemed like good luck at the time. Sometimes it was hard to tell the difference.

Jezal stumbled up to his horse, grabbed the saddle-bow and dragged himself clumsily up. Longfoot and Ninefingers were already in their saddles. Bayaz was just shoving his staff back into its place with trembling hands. Somewhere in the city behind them, a bell began to clang.

'Oh dear,' said Longfoot, peering wide-eyed through the multitude of statues. 'Oh dear.'

'Bad luck,' whispered Jezal.

Ferro was staring at him. 'What?'

'Nothing.' Jezal gritted his teeth, and gave his horse the spurs.

There was no such thing as luck. Luck was a word idiots used to explain the consequences of their own rashness, and selfishness, and stupidity. More often than not bad luck meant bad plans.

And here was the proof.

She had warned Bayaz that there was something in the city besides her and five pink fools. She had warned him, but no one had listened. People only believe what they want to. Idiots, anyway.

She watched the others, while she rode. Quai, on the seat of the jolting cart, eyes narrowed and fixed ahead. Luthar, with his lips curled back from his teeth, pressed into the saddle in the crouch of a practised rider. Bayaz, jaw clenched tight, face pale and drawn, clinging on grimly. Longfoot, looking often over his shoulder, eyes wide with fear and alarm. Ninefingers, jolting in his saddle, breathing hard, spending more time looking at his reins than at the road. Five idiots, and her.

She heard a growl and saw a creature squatting on a low roof. It was like nothing she had seen before a bent-over ape, twisted and long-limbed. Apes do not throw spears, however. Her eyes followed it as it arced downwards. It thudded into the side of the cart and stuck there, wobbling, then they were past and clattering on down the rutted street.

That one might have missed, but there were more creatures in the ruins ahead. Ferro could see them moving in the shadowy buildings. Scuttling along the roofs, lurking in the crumbling windows, the gaping doorways. She was tempted to try a shaft at one of them, but what would have been the point? There were a lot of them out there. Hundreds, it felt like. What good would killing one of them do, when they were soon left behind? A waste of an arrow.

A rock crashed down suddenly beside her and she felt a fragment from it whiz past and nick the back of her hand. It left a bead of dark blood on her skin. Ferro frowned and put her head down, keeping herself low to the bouncing back of her horse. There was no such thing as luck.

But there was no point being a bigger target.

Logen thought he'd left the Shanka far behind, but after the first shock of seeing one, it came as no surprise. He should've known by now. Only friends get left behind. Enemies are always at your heels.

The bells were all around them, echoing out of the ruins. Logen's skull was full of their clashing, stabbing through the cracking hooves and the shrieking wheels and the rushing air. Clanging, far away, near at hand, ahead and behind. The buildings rushed by, grey shapes full of danger.

He saw something flash by and bounce spinning from the stones. A spear. He heard another twitter behind, then saw one clatter across the road in front. He swallowed, narrowing his eyes against the wind in his face, and tried not to imagine a spear thudding into his back. It wasn't too difficult. Just holding on was taking all his concentration.

Ferro had turned in her saddle to shout something at him over her shoulder, but her words were lost in the noise. He shook his head at her and she stabbed her arm furiously at the road ahead. Now he saw it. A crevasse opened in the road before them, rushing up at a gallop. Logen's mouth gaped just as wide and he gave a breathless squeak of horror.

He dragged on the reins, and his horse's hooves slipped and skittered on the old stones, turning sharply to the right. The saddle lurched and Logen clung on, cobbles flying by underneath in a grey blur, the edge of the great chasm rushing past no more than a few strides away on his left, cracks from it cutting out into the crumbling road. He could feel the others nearby, could hear voices shouting, but he couldn't hear their words. He was too busy rolling and bouncing painfully in the saddle, willing himself to stay on, all the while whispering.

'Still alive, still alive, still alive . . .'

A temple loomed up towards them, straddling the road, its towering pillars still intact, a monstrous triangular weight of stone still standing on top. The cart crashed between two of the columns and Logen's horse found its way between two others, dipping suddenly into shadow and back out, all of them surging into a wide hall, open to the sky. The crack had swallowed the wall to the left, and if there had ever been a roof it had vanished long ago. Logen rode on, breathless, eyes fixed on a wide archway straight ahead, a square of brightness in the dark stone, bouncing and jolting with the movement of his horse. That was safety, Logen told himself. If they could get through there they were away. If they could only get through there . . .

He didn't see the spear coming, but if he had there would've been nothing he could've done. It was lucky, in a way, that it missed his leg. It thudded deep into horseflesh just in front of it. That was less lucky. He heard the horse snort as its legs buckled, as he came free of the saddle, mouth dropping open and no sound coming out, the floor of the hall flashing up to meet him. Hard stone crunched into his chest and snatched his wind away. His jaw smacked against the ground and his head flooded with blinding light. He bounced once, then flopped over and over, the world spinning crazily around him, full of strange sound and blinding sky. He slid to a stop on his side.

He lay in a daze, groaning softly, his head reeling, his ears ringing, not knowing where he was or even who. Then the world came suddenly back together.

He jerked his head up. The chasm was no more than a spear's length from him, he could hear the water rushing far away in its bottom. He rolled over, away from his horse, trickles of dark blood working their way along the grooves in the stones underneath it. He saw Ferro, down on one knee, pulling arrows from her quiver and shooting them towards the pillars they had ridden between a few moments before.

There were Shanka there, a lot of them.

'Shit,' grunted Logen, scrambling back, the heels of his boots scraping at the dusty stones.

'Come on!' shouted Luthar, sliding down from his saddle, half hopping across the dusty floor. 'Come on!'

A Flathead charged towards them, shrieking, a great axe in its hand. It leaped up suddenly and turned over in the air, one of Ferro's arrows stuck through its face, but there were others. There were a lot more, creeping around the pillars, spears ready to throw.

'Too many!' shouted Bayaz. The old man frowned up at the great columns, the huge weight of stone above them, the muscles of his jaw clenching tight. The air around him began to shimmer.

'Shit.' Logen stumbled like a drunkard across to Ferro, his balance all gone, the hall tipping back and forward around him, the sound of his own heart pounding in his ears. He heard a sharp bang and a crack shot up one of the pillars, a cloud of dust flying out from it. There was a grinding rumble as the stone above began to shift. A couple of the Shanka looked up as fragments rained down on them, pointing and gibbering.

Logen grabbed tight hold of Ferro's wrist. 'Fuck!' she hissed, fumbling an arrow as he half fell and dragged her over, scrambled up and started to pull her after him. A spear zipped past them and clattered across the stones, tumbled off over the edge of the crack into empty space. He could hear the Shanka moving, grunting and growling to each other, starting to swarm between the pillars and into the hall.

'Come on!' shouted Luthar again, taking a couple of limping steps forward and beckoning wildly.

Logen saw Bayaz standing, his lips curled back and his eyes bulging from his skull, the air around him rippling and twisting, the dust on the ground lifting slowly and curling up around his boots. There was an almighty crack and Logen looked over his shoulder to see a great lump of carved stone plummet down from above. It hit the ground with a crash that made the floor shake, crushing an unlucky Shanka to flat nothing before it could even scream, a jagged sword clattering across the ground and a long spatter of dark blood the only signs that it had ever existed. But more were coming, he could see the black shapes of them through the flying dust, charging forward, weapons held high.

One of the pillars split in half. It buckled, moving with ludicrous slowness, pieces of it flying forward into the hall. The vast mass of stone above began to crack apart, tumbling downwards in chunks as big as houses. Logen turned and flung himself on his face and dragged Ferro down with him, grovelling on the ground, squeezing his eyes shut, throwing his hands over his head.

There was a giant crashing, tearing, splitting such as Logen had never heard in all his life. A roaring and groaning of tortured earth as though the world was falling in. Perhaps it was. The ground bucked and trembled underneath him. There was another deafening crash, a long clattering and scraping, a gentle clicking, then something close to quiet.

Logen unclenched his aching jaw and opened his eyes. The air was full of stinging dust, but it felt as if he was lying on some kind of slope. He coughed and tried to move. There was a sharp grinding sound beneath his chest and the stone underneath him began to shift, the slope getting steeper. He gasped and pressed himself back flat against it, clinging to it with his fingertips. He still had his hand clenched round Ferro's arm, and he felt her fingers squeeze tight into his wrist. He turned his head slowly to look around him, and froze.

The pillars were gone. The hall was gone. The floor was gone. The vast crack had swallowed them all up, and now yawned underneath him. Angry water slapped and hissed at the shattered ruins far below. Logen gaped, hardly able to believe his eyes. He was lying sideways on a huge slab of stone, until a moment ago part of the floor of the hall, now teetering at an angle on the very edge of a plunging cliff.

Ferro's dark fingers were clamped round his wrist, her ripped sleeve gathered up round her elbow, sinews standing out stark from her brown forearm with the effort. Beyond that he could see her shoulder, beyond that her rigid face. The rest of her was invisible dangling over the edge of the slab and into the yawning air.

'Ssss,' she hissed, yellow eyes wide, fingers scrabbling desperately for a hand hold on the smooth slope. A chunk of stone cracked suddenly from the ragged edge and Logen heard it fall, pinging and bouncing from the ruptured earth.

'Shit,' he whispered, hardly daring even to breathe. What the hell were the chances of this? Say one thing for Logen Ninefingers, say that he has poor luck.

He crawled his free hand up the pitted stone until he found a shallow ridge to cling to. He lifted himself inch by inch towards the edge of the block above. He flexed his arm and started to drag at Ferro's wrist.

There was a horrifying scraping and the stone underneath him jolted and tipped slowly upwards. He whimpered and pressed himself back against it, willing it to stop. There was a sickening jolt and some dust filtered down into his face. Stone squealed as the block swung ever so slowly back the other way. He lay there, gasping. No way up, no way down.

'Ssss!' Ferro's eyes flicked to their hands, gripped tight round each other's wrists. She jerked her head up towards the edge of the block, then down towards the gaping crack behind.

'Have to be realistic,' she whispered. Her fingers uncurled, letting him go.

Logen remembered hanging from a building, far above a circle of yellow grass. He remembered sliding back, whispering for help. He remembered Ferro's hand closing round his, pulling him up. He slowly shook his head, and gripped her wrist tighter than ever.

She rolled her yellow eyes at him. 'Stupid fucking pink!'

Jezal coughed, turned over, and spat out dust. He blinked around him. Something was different. It seemed much brighter than it had been, and the edge of the crack was much nearer. Not far away at all, in fact.

'Uh,' he breathed, words failing him. Half the building had collapsed. The rear wall was still standing, and one of the pillars at the far end, broken off halfway up. All the rest was gone, vanished into the yawning chasm. He staggered up, wincing as his weight went onto his bad leg. He saw Bayaz lying propped against the wall nearby.

The Magus' withered face was streaked with sweat, bright eyes glittering in black circles, bones of his face poking through stretched skin. He looked like nothing so much as a week-old corpse. It was a surprise to see him move at all, but Jezal watched him raise one palsied hand to point towards the crack. 'Get them,' he croaked.

The others.

'Over here!' Ninefingers' voice came strangled-sounding from beyond the edge of the crevasse. So he was alive, at least. One great slab was sticking up at an angle and Jezal shuffled gingerly towards it, worried that the floor might suddenly give way beneath him. He peered over into the chasm.

The Northman was lying spread out on his front, left hand up near the top edge of the tilting block, right fist near the bottom clutched tight round Ferro's wrist. Her body was out of sight, her scarred face just visible. They both looked equally horrified. Several tons of stone, rocking, ever so gently, balanced on the finest of margins. It was plain that it might easily slide into the abyss at any moment.

'Do something . . .' whispered Ferro, not even daring to raise her voice. Jezal noticed that she did not suggest any specifics, however.

He licked at the slot in his lip. Perhaps if he were to put his weight on this end it would tilt back level and they could simply crawl off? Could it possibly be so straightforward? He reached out carefully, thumbs rubbing nervously against fingertips, all suddenly weak and sweaty-feeling. He laid his hand gently on the ragged edge while Ninefingers and Ferro stared, holding their breath.

He applied the very slightest pressure, and the slab began to swing smoothly downwards. He put a little more weight on it. There was a loud grating sound and the whole block gave a horrifying lurch.

'Don't fucking push it!' screamed Ninefingers, clinging to the smooth rock with his fingernails.

'What then?' squealed Jezal.

'Get something!'

'Get anything!' hissed Ferro.

Jezal stared around wildly, saw no source of help. Of Longfoot and Quai there was no sign. Either they were dead somewhere at the bottom of the chasm, or they had made a timely bid for freedom. Neither one would have much surprised him. If anyone was going to be saved, Jezal would have to do it by himself.

He dragged his coat off, started to twist it round to make a kind of rope. He weighed it in his hand, shaking his head. Surely this would never work, but what were the choices? He stretched it out, then swung one end over. It slapped against the stone a few inches short of Logen's clutching fingers, sending up a puff of grit.

'Alright, alright, try again!'

Jezal lifted the coat up high, leaning out over the slab as far as he dared, and swung it down again. The arm flopped out just far enough for Logen to seize hold of.

'Yes!' He wound it round his wrist, the material dragging out tight over the edge of the slab.

'Yes! Now pull it!'

Jezal gritted his teeth and hauled, his boots slipping in the dust, his sore arm and his sore leg aching with the effort. The coat came towards him, slowly, slowly, sliding over the stone, inch by torturous inch.

'Yes!' grunted Ninefingers working his shoulders up the slab.

'Pull it!' growled Ferro, wriggling her hips up over the edge and onto the slope.

Jezal hauled for all he was worth, eyes squeezed almost shut, breath hissing between his teeth. A spear clattered down beside him and he looked up to see a score or more Flatheads gathered on the far side of the great crack, waving their misshapen arms. He swallowed and looked away from them. He could not allow himself to think of the danger. All that mattered was to pull. To pull and pull and not let go, however much it hurt. And it was working. Slowly, slowly, they were coming up. Jezal dan Luthar, the hero at last. He would finally have earned his place on this cursed expedition.
