He saw all of this in one prodigious glance. In his second the vision laid before him began to change.

From the comer of his eye he registered that the rest of the world - the yard, and the men who'd occupied it, the houses: the wall he'd been toppling from - all were winking out of existence. Suddenly he was hanging in the air, the carpet vaster by the moment beneath him, its glorious configurations filling his head.

The design was shifting, he saw. The knots were restless, trembling to slip themselves, and the colours seemed to be merging into each other, new forms springing from this marriage of dyes.

Implausible as it seemed, the carpet was coming to life.

A landscape - or rather a confusion of landscapes thrown together in fabulous disarray - was emerging from the warp and the weft. Was that not a mountain he could see below him, pressing its head up through a cloud of colour?; and was that not a river?; and could he not hear its roar as it fell in white water torrents into a shadowed gorge? There was a world below him.

And he was suddenly a bird, a wingless bird hovering for a breathless instant on a balmy, sweet-scented wind, sole witness to the miracle sleeping below.

There was more to claim his eye with every thump of his heart.

A lake, with myriad islands-dotting its placid waters like breaching whales. A dappled quilt of fields, their grasses and grains swept by the same tides of air that kept him aloft. Velvet woodland seeping up the sleek flank of a hill, on whose pinnacle a watchtower perched, sun and cloud-shadow drifting across its white walls.

There were other signs of habitation too, though nothing of the people themselves. A duster of dwellings hugging a river bend; several houses beetling along the edge of a cliff, tempting gravity. And a town too, laid out in a city-planner's nightmare, half its streets hopelessly serpentine, the other half cul-de-sacs.

The same casual indifference to organization was evident everywhere, he saw. Zones temperate and intemperate, fruitful and barren were thrown together in defiance of all laws geological or climatic, as if by a God whose taste was for contradiction.

How fine it would be to walk there, he thought, with so much variety pressed into so little space, not knowing whether turning the next comer would bring ice or fire. Such complexity was beyond the wit of a cartographer. To be there, in that world, would be to live a perpetual adventure.

And at the centre of this burgeoning province, perhaps the most awesome sight of all. A mass of slate-coloured cloud, the innards of which were in perpetual, spiralling motion. The sight reminded him of the birds wheeling above the house in flue Street - an echo of this greater wheel.

At the thought of them, and the place he'd left behind, he heard their voices - and in that moment the wind that had swept up from the world below, keeping him aloft, faltered.

He felt the horror in his stomach first, and then his bowels: he was going to fail.

The tumult of the birds grew louder, crowing their delight at his descent. He, the usurper of their element; he, who had snatched a glimpse of a miracle, would now be dashed to death upon it.

He staved to yell, but the speed of his fall stole the cry from his tongue. The air roared in his ears and tore at his hair. He tried to spread his arms to slow his descent but the attempt instead threw him head over heels, and over again, until he no longer knew earth from sky. There was some mercy in this, he dimly thought. At least he'd be blind to death's proximity. Just tumbling and tumbling until - the world went out.

He fell through a darkness unrelieved by stars, the birds still loud in his ears, and hit the ground, hard.

It hurt, and went on hurting, which struck him as odd. Oblivion, he'd always assumed, would be a painless condition. And soundless too. But there were voices.

‘Say something...' one of them demanded, ‘... if it's only goodbye.'

There was laughter now.

He opened his eyes a hair's breadth. The sun was blindingly bright, until Gideon's bulk eclipsed it.

‘Have you broken anything?' the man wanted to know.

Cal opened his eyes a fraction wider.

‘Say something, man.'

He raised his head a few inches, and looked about him. He was lying in the yard, on the carpet.

‘What happened?'

‘You fell off the wall,' said Shane.

‘Must have missed your footing,' Gideon suggested.

‘Fell,' Cal said, pulling himself up into a sitting position. He felt nauseous.

‘Don't think you've done much damage,' said Gideon. ‘A few scrapes, that's all.'

Cal ‘looked down at himself, verifying the man's remark. He'd taken skin off his right arm from wrist to elbow, and there was tenderness down his body where he'd hit the ground, but there were no sharp pains. The only real harm was to his dignity, and that was seldom fatal.

He got to his feet, wincing, eyes to the ground. The weave was playing dumb. There was no tell-tale tremor in the rows of knots, no sign that hidden heights and depths were about to make themselves known. Nor was there any sign from the others that they'd seen anything miraculous. To all intents and purposes the carpet beneath his feet was simply that: a carpet.

He hobbled towards the yard gate, offering a muttered thanks to Gideon. As he stepped out into the alley, Bazo said: ‘Yer bird flew off.'

Cal gave a small shrug and went on his way.

What had he just experienced? An hallucination, brought on by too much sun or too little breakfast? If so, it had been startlingly real. He looked up at the birds, still circling overhead: They sensed something untoward here too; that was why they'd gathered. Either that, or they and he were sharing the same delusion.

All, in sum, that he could be certain of was his bruising. That, and the fact that though he was standing no more than two miles from his father's house, in the city in which he'd spent his entire life, he felt as homesick as a lost child.

CONTACT

Immacolata crossed the width of heat-raddled pavement between the-steps of the hotel and the shaded interior of Shadwell's Mercedes, she suddenly let out a cry. Her hand went to her head, the sunglasses she always wore in the Kingdom's public places falling from her face.

Shadwell was swiftly out of the car, and opening the door, but his passenger shook her head.

‘Too bright,' she murmured, and stumbled back through the swing-doors into the vestibule of the hotel. It was deserted. Shadwell came in swift pursuit, to find Immacolata standing as far from the door as her legs would carry her. The wraith-sisters were guarding her, their presences distressing the stale air, but he couldn't prevent himself from snatching the opportunity, in the guise of legitimate concern, to reach and touch the woman. Such contact was anathema to her, and a joy to him made more potent because she forbade it. He was obliged therefore to exploit any occasion when he might pass such contact off as accidental.

The ghosts chilled his skin with their disapproval, but Immacolata was quite able to protect her inviolability. She turned, her eyes raging at his presumption. He immediately removed his hand from her arm, his fingers tingling. He would count the minutes until he had a private moment in which to put them to his lips.

‘I'm sorry,' he said. ‘I was concerned.'

A voice intervened. The receptionist had emerged from his room, a copy of Sporting Life in hand.

‘Can I be of help?' he offered.

‘No, no...' said Shadwell.

The receptionist's eyes were not on him, however, but on Immacolata.

Touch of heat stroke, is it?' he said.

‘Maybe,' said Shadwell. Immacolata had moved to the bottom of the stairs, out of the receptionist's enquiring gaze. Thank you for your concern. The receptionist made a face, and returned to his armchair. Shadwell went to Immacolata. She had found the shadows; or the shadows had found her.
