Was it wise to believe always what the dead told you?; were they purged of all deceit by the act of dying, and delivered into their new state like saints? Cleve could not believe such naivete. More likely they took their talents with them, good and bad, and used them as best they could. There would be shoemakers in paradise, wouldn't there?; foolish to think they'd forgotten how to sew leather.

So perhaps Edgar Tait lied about the city. There was more to that place than Billy knew. What about the voices on the wind?, the man with the knife, dropping it amongst a litter of weapons before moving off to God alone knew where? What ritual was that?

Now - with the fear used up, and no untainted reality left to cling to, Cleve saw no reason not to go to the city willingly. What could be there, in those dusty streets, that was worse than what he had seen in the bunk below him, or what had happened to Lowell and Nayler? Beside such atrocities the city was a haven. There was a serenity in its empty thoroughfares and plazas; a sense Cleve had there that all action was over, all rage and distress finished with; that these interiors (with the bath running and the cup brimming) had seen the worst, and were now content to sit out the millennium. When that night brought sleep, and the city opened up in front of him, he went into it not as a frightened man astray in hostile territory, but as a visitor content to relax a while in a place he knew too well to become lost in, but not well enough to be weary of.

As if in response to this new-found ease, the city opened itself to him. Wandering the streets, feet bloody as ever, he found the doors open wide, the curtains at the windows drawn back. He did not disparage the invitation they offered, but went to look more closely at the houses and tenements. On closer inspection he found them not the paradigms of domestic calm he'd first taken them for. In each he discovered some sign of violence recently done. In one, perhaps no more than an overturned chair, or a mark on the floor where a heel had slid in a spot of blood; in others, the manifestations were more obvious. A hammer, its claw clotted, had been left on a table laid with newspapers. There was a room with its floorboards ripped up, and black plastic parcels, suspiciously slick, laid beside the hole. In one, a mirror had been shattered; in another, a set of false teeth left beside a hearth in which a fire flared and spat.

They were murder scenes, all of them. The victims had gone - to other cities, perhaps, full of slaughtered children and murdered friends - leaving these tableaux fixed forever in the breathless moments that followed the crime. Cleve walked down the streets, the perfect voyeur, and peered into scene after scene, reconstructing in his mind's eye the hours that had preceded the studied stillness of each room. Here a child had died: its cot was overturned; here someone had been murdered in their bed, the pillow soaked in blood, the axe on the carpet. Was this damnation then?; the killers obliged to wait out some portion of eternity (all of it, perhaps) in the room they'd murdered in?

Of the malefactors themselves he saw nothing, though logic implied that they must be close by. Was it that they had the power of invisibility to keep themselves from the prying eyes of touring dreamers like himself?; or did a time in this nowhere transform them, so that they were no longer flesh and blood, but became part of their cell: a chair, a china doll?

Then he remembered the man at the perimeter, who'd come in his fine suit, bloody-handed, and walked out into the desert. He had not been invisible.

'Where are you?' he said, standing on the threshold of a mean room, with an open oven, and utensils in the sink, water running on them. 'Show yourself.'

A movement caught his eye and he glanced across to the door. There was a man standing there. He had been there all along, Cleve realized, but so still, and so perfectly a part of this room, that he had not been visible until he moved his eyes and looked Cleve's way. He felt a twinge of unease, thinking that each room he had peered into had, most likely, contained one or more killers, each similarly camouflaged by statis. The man, knowing he'd been seen, stepped out of hiding. He was in late middle-age, and had cut himself that morning as he shaved.

'Who are you?' he said. 'I've seen you before. Walking by.'

He spoke softly and sadly; an unlikely killer, Cleve thought.

'Just a visitor,' he told the man.

'There are no visitors, here,' he replied, 'only prospective citizens.'

Cleve frowned, trying to work out what the man meant. But his dream-mind was sluggish, and before he could solve the riddle of the man's words there were others.

'Do I know you?' the man asked. 'I find I forget more and more. That's no use, is it? If I forget I'll never leave, will I?'

'Leave?' Cleve repeated.

'Make an exchange,' the man said, re-aligning his toupe.

'And go where?'

'Back. Do it over.'

Now he approached Cleve across the room. He stretched out his hands, palms up; they were blistered.

'You can help me,' he said, 'I can make a deal with the best of them.'

'I don't understand you.'

The man clearly thought he was bluffing. His upper lip, which boasted a dyed black moustache, curled. 'Yes you do,' he said. 'You understand perfectly. You just want to sell yourself, the way everybody does. Highest bidder, is it? What are you, an assassin?'

Cleve shook his head. 'I'm just dreaming,' he replied.

The man's fit of pique subsided. 'Be a friend,' he said. 'I've got no influence; not like some. Some of them, you know, they come here and they're out again in a matter of hours. They're professionals. They make arrangements. But me? With me it was a crime of passion. I didn't come prepared. I'll stay here 'til I can make a deal. Please be a friend.'

'I can't help you,' Cleve said, not even certain of what the man was requesting.

The killer nodded. 'Of course not,' he said, 'I didn't expect...'

He turned from Cleve and moved to the oven. Heat flared up from it and made a mirage of the hob. Casually, he put one of his blistered palms on the door and closed it; almost as soon as he had done so it creaked open again. 'Do you know just how appetising it is; the smell of cooking flesh?' he said, as he returned to the oven door and attempted to close it a second time. 'Can anybody blame me? Really?'

Cleve left him to his ramblings; if there was sense there it was probably not worth his labouring over. The talk of exchanges and of escape from the city: it defied Cleve's comprehension.

He wandered on, tired now of peering into the houses. He'd seen all he wanted to see. Surely morning was close, and the bell would ring on the landing. Perhaps he should even wake himself, he thought, and be done with this tour for the night.

As the thought occurred, he saw the girl. She was no more than six or seven years old, and she was standing at the next intersection. This was no killer, surely. He started towards her. She, either out of shyness or some less benign motive, turned to her right and ran off. Cleve followed. By the time he had reached the intersection she was already a long way down the next street; again he gave chase. As dreams would have such pursuits, the laws of physics did not pertain equally to pursuer and pursued. The girl seemed to move easily, while Cleve struggled against air as thick as treacle. He did not give up, however, but pressed on wherever the girl led. He was soon a good distance from any location he recognized in a warren of yards and alleyways - all, he supposed, scenes of blood-letting. Unlike the main thoroughfares, this ghetto contained few entire spaces, only snatches of geography: a grass verge, more red than green; a piece of scaffolding, with a noose depending from it; a pile of earth. And now, simply, a wall.
