The wheeling sound, and the picture it evoked, began to dizzy him. He suddenly felt weak, even afraid.

This was no time for such frailties, he chided himself. He had to claim the bird before it flew off again. He picked up his pace. At the top of the stairs he manoeuvred past several items of bedroom furniture, and opened one of the several doors that he was presented with. The room he had chosen was adjacent to the one whose sill 33 occupied. Sun streamed through the curtainless window; the stale heat brought fresh sweat to his brow. The room had been emptied of furniture, the only souvenir of occupancy a calendar for the year 1961. On it, a photograph of a lion beneath a tree, its shaggy, monolithic head laid on vast paws, its gaze contemplative.

Cal went out on to the landing again, selected another door, and was this time delivered into the right room. There, beyond the grimy glass, was the pigeon.

Now it was all a question of tactics. He had to be careful not to startle the bird. He approached the window cautiously. 0n the sun-drenched sill 33 cocked its head, and blinked its eyes but made no move. Cal held his breath, and put his hand on the frame to haul the window up, but there was no budging it. A quick perusal showed why. The frame had been sealed up years ago, a dozen or more nails driven deep into the wood. A primitive form of crime prevention, but no doubt reassuring to an old woman living alone.

From the yard below, he heard Gideon's voice. Peering down, he could just sec the trio dragging a large rolled-up carpet out of the house, Gideon giving orders in a ceaseless stream.

‘- to my left, Bazo. Left! Don't you know which is your left?'

‘I'm going left.'

‘Not your left, yer idiot. My left.'

The bird on the sill was undisturbed by this commotion. It seemed quite happy on its perch.

Cal headed basic downstairs, deciding as he went that the only option remaining was to climb up on to the yard wall and see if he couldn't coax the bird down from there. He cursed himself for not having brought a pocketful of grain. Coos and sweet words would just have to do.

By the time he stepped out into the heat of the yard once more, the removal men had successfully manhandled the carpet out of the house, and were taking a rest after their exertions.

‘No luck?' said Shane, seeing Cal emerge.

The window won't budge. I'll have to try from down here.'

He caught a deprecating look from Bazo. ‘You'll never reach the bugger from here,' rite man said, scratching the expanse of beer-gut that gleamed between T-shirt and belt.

‘I'll try from the wall; said Cal.

‘Watch yerself-' Gideon said.

‘Thanks.'

‘- you could break yer back-.'

Using pits in the crumbling mortar for foothold, Cal hauled himself up on to the eight-toot wall that divided this yard from its neighbour.

The sun was hot on his neck and the top of his head, and thing of the giddiness he'd experienced climbing the stairs returned. He straddled the wall as though it were a horse, until he got used to the height. Though the perch was the width of a brick, and offered ample enough walking space, heights and he had never been happy companions.

‘Looks like it's been a nice piece of handiwork,' said Gideon, in the yard below. Cal glanced own to see that the West Indian was now on his haunches beside the carpet, which he'd rolled out far enough to expose an elaborately woven border.

Bazo wandered over to where Gideon crouched, and scrutinized the property. He was balding, Cal could see, his hair scrupulously pasted down with oil to conceal the spot.

‘Pity it's not in better nick,' said Shane.

‘Hold yer horses; said Bazo. ‘Let's have a better look.'

Cal returned his attention to the problem of standing upright. At least the carpet would divert his audience for a few moments; long enough, he prayed, for him to get to his feet. There was no breath of wind here to alleviate the fury of the sun; he could feel sweat trickle down his torso and glue his underwear to his buttocks. Gingerly, he started to stand, bringing one leg up into a kneeling position - both hands; dinging to the brick like grim death.

From below, there were murmurs of approval as more of the carpet was exposed to light.

‘Look at the work in that; said Gideon.

‘Are you thinkin' what I'm thinkin?' said Bazo, his voice lowered.

‘I don't know ‘til you tell me,' came Gideon's reply.

‘What say we take it down to Gilchrist's. We might get a price for this.'

‘The Chief'll know it's gone,' Shane protested.

‘Keep it down; said Bazo, quietly reminding his companions of Cal's presence. In fad Cal was far too concerned with his inept tight-rope act to bother himself with their petty theft. He had finally got the soles of both feet up on to the top of the wall, and was about to try standing up.

In the yard, the conversation went on.

Take the far end, Shane, let's have a look at the whole thing...

‘D'you think it's Persian?'

‘Haven't a fuckin' clue.'

Very slowly, Cal stood upright, his arms extended at ninety degrees from his body. Feeling as stable as he was ever going to feel, he chanced a quick look up at the window sill. The bird was still there.

From below he heard the sound of the carpet being unrolled further, the men's grunts punctuated with words of admiration.

Ignoring their presence as best he could, he took his first faltering step along the wall.

‘Hey there...' he murmured to the escapee'... remember me?'

33 took no notice. Cal advanced a second trembling step, and a third, his confidence growing. He was getting the trick of this balancing business now.

‘Come on down,' he coaxed, a prosaic Romeo.

The bird finally seemed to recognize his owner's voice, and cocked his head in Cal's direction.

‘Here, boy...' Cal said, tentatively raising his hand towards the window as he risked another step.

At that instant either his foot slipped or the brick gave way beneath his heel. He heard himself loose a yell of alarm, which panicked the birds lining the sill. They were up and off, their wing-beats ironic applause, as he flailed on the wall. His panicked gaze went first to his feet, then to the yard below.

No, not the yard; that had disappeared. It was the carpet he saw. It had been entirely unrolled, and it filled the yard from wall to wall.

What happened next occupied mere seconds, but either his mind was lightning fast, or the moments played truant, for it seemed he had all the time he needed Time to appreciate the startling intricacy of the design laid out beneath him; an awesome proliferation of exquisitely executed detail. Age had bled brightness from the colours of the weave, mellowing vermilion to rose, and cobalt to a chalky blue, and here and there the carpet had become thread-bare, but from where Cal teetered the effect was still overwhelming. Every inch of the carpet was worked with motifs. Even the border brimmed with designs, all subtly different from their neighbours. The effect was not over-busy; every detail was dear to Cal's feasting eyes. In one place a dozen motifs congregated as if banded together; in another, they stood apart rival siblings. Some kept their station along the border; others spilled into the main field, as if eager to join the teeming throng there.

In the field itself ribbons of colour described arabesques across a background of sultry browns and greens, forms that were pure abstraction - bright jottings from some wild man's diary - jostling with stylized flora and fauna. But this complexity paled beside the centre piece of the carpet: a huge medallion, its colours as various as a summer garden; into which a hundred subtle geometries had been cunningly woven, so that the eye could read each pattern as flower or theorem, order or turmoil, and find each choice echoed somewhere in the grand design.
