At the bottom of the street he lost sight of his quarry behind the rooftops, and so made a detour to the foot bridge that crossed the Woolton Road, mounting the steps three and four at a time. From the top he was rewarded with a good view of the city. North towards Woolton Hill, and off East, and South-East, over Allerton towards Hunt's Cross. Row upon row of council house roofs presented themselves; shimmering in the fierce heat of the afternoon, the herringbone rhythm of the dose-packed streets rapidly giving way to the industrial wastelands of Speke.

Cal could see the pigeon too, though he was a rapidly diminishing dot.

It mattered little, for from this elevation 33's destination was perfectly apparent. Less than two miles from the bridge the air was full of wheeling birds, drawn to the spot no doubt by some concentration of food in the area. Every year brought at least one such day, when the ant or gnat population suddenly boomed, and the bird life of the city was united in its gluttony. Gulls up from the mud banks of the Mersey, flying tip to tip with thrush and jackdaw and starling, all content to join the jamboree while the summer still warmed their backs.

This, no doubt, was the call 33 had heard. Bored with his balanced diet of maize and maple peas, tired of the pecking order of the loft and the predictability of each day - the bird had wanted out: wanted up and away. A day of high life; of food that had to be chased a little, and tasted all the better for that; of the companionship of wild things. All this went through Cal's head, in a vague sort of way, while he watched the circling flocks.

It would be perfectly impossible, he knew, to locate an individual bird amongst these riotous thousands. He would have to trust that 33 would be content with his feast on the wing, and when he was, sated do as he was trained a do, and come home. Nevertheless, the sheer spectacle of, so many birds exercised a peculiar fascination, and crossing the bridge, Cal began to make his way towards the epicentre of this feathered cyclone.

THE PURSUERS

The woman at the window of the Hanover Hotel drew bade the grey curtain and looked own at the street below.

‘Is it possible... ?' she murmured to the shadows that held court in the comer of the room. There was no answer to her question forthcoming, nor did there need to be. Unlikely as it seemed the trail had incontestably led here, to, this dog-tired city, lying bruised and neglected beside a river that had once borne stave ships and, cotton ships and could now barely carry its own weight out to sea. To Liverpool.

‘Such a place,' she said. A minor dust-dervish had whipped itself up in the street outside, lifting antediluvian litter into the air.

‘Why are you so surprised?' said the man who half lay and half sat on the bed, pillows supporting his impressive frame, hands linked behind his heavy head. The face was wide, the features upon it almost too expressive, like those of an actor who'd made a career of crowd-pleasers, and grown expert in cheap effects. His mouth, which knew a thousand variations of the simile, found one that suited his leisurely mood, and said: They've led us quite a dance. But we're almost there. Don't you feel it? I do.'

The woman glanced back at this man. He had taken off the jacket that had been her last loving gift to him, and thrown, it over the back of the chair. The shirt beneath was sweat sodden at the armpits, and the flesh of his face looked waxen in the afternoon light. Despite all she felt for him - and that was enough to make her tearful of computation - he was only human, and today, after so much heat and travel, he wore every one of his fifty-two years plainly. In the time they had been together, pursuing the Fugue, she had lent him what strength she could, as he in his turn had lent her his wit, and his expertise in surviving this realm. The Kingdom of the Cuckoo, the Families had always called it, this wretched human world which she had endured for vengeance's sake.

But very soon now the chase would be over. Shadwell the man on the bed - would profit by what they were so very dose to finding, and she, seeing their quarry besmirched and sold into slavery, would be revenged. Then she would leave the Kingdom to its grimy ways, and happily.

She turned her attentions back to the street. Shadwell was right. They had been led a dance. But the music would cease soon enough.

From where Shadwell lay Immacolata's silhouette was clear against the window. Not for the first time his thoughts turned to the problem of how he would sell this woman. It was a purely academic exercise, of course, but one that pressed his skills to their limits.

He was by profession a salesman; that had been his business since his early adolescence. More than his business, his genius. He prided himself that there was nothing alive or dead he could not find a buyer for. In his time he had been a raw sugar merchant, a small arms salesman, a seller of dolls, dogs, life-insurance, salvation rags and lighting fixtures. He had trafficked in Lourdes water and hashish, in Chinese screens and patented cures for constipation. Amongst this parade of items there had of course been frauds and fakes aplenty, but nothing, nothing that he had not been able to foist upon the public sooner or later, either by seduction or intimidation.

But she - Immacolata, the not quite woman he had shared his every waking moment with these past many years she, he knew, would defy his talents as a salesman.

For one, she was paradoxical, and the buying public had little taste for that. They wanted their merchandise shorn of ambiguity: made simple and safe. She was not safe; oh, certainly nor not with her terrible rage and her still more terrible alleluias; nor was she simple. Beneath the incandescent beauty of her fare, behind eyes that concealed centuries yet could be so immediate they drew blood, beneath the deep olive skin, the Jewess' skin, there lay feelings that would blister the air if given vent.

She was too much herself to be sold, he decided - not for the first time - and told himself to forget the exercise. It was one he could never hope to master; why should he torment himself with it? Immacolata turned away from the window.

‘Arc you rested now?' she asked him.

‘It was you wanted to get out of the sun; he reminded. her. ‘I'm ready to start whenever you are. Though I haven't a clue where we begin...'

‘That's not so difficult; Immacolata said. ‘Remember what my sister prophesied? Events are close to crisis-point.'

As she spoke, the shadows in the comer of the room stirred afresh, and Immacolata's two dead sisters showed their ethereal skirts. Shadwell had never been easy in their presence, and they in their turn had always despised him. But the old one, the Hag, the Beldam, had skills as an oracle, no doubt of that. What she saw in the filth of her sister, the Magdalene's after-birth, was usually proved correct.

‘The Fugue can't stay hidden much longer; said Immacolata. ‘As soon as it's moved it creates vibrations. It can't help itself. So much life, pressed into such a hideway.'

‘And do you feel any of these... vibrations?' said Shadwell, swinging his legs over the edge of the bed and standing up.

Immacolata shook her head. ‘No. Not yet. But we should be ready.'

Shadwell picked up his jacket, and slipped it on. The fining shimmered, casting filaments of seduction across the room. By their momentary brightness he caught sight of the Magdalene and the Hag. The old woman covered her eyes against the spillage from the jacket, fearful of its power. The Magdalena did not concern herself; her lids had long ago been sewn closed over sockets blind from birth.

‘When the movements begin it may take an hour or two to pin-point the location; said Immacolata.

‘An hour?' Shadwell replied. The pursuit that had finally led them here seemed today to have been a lifetime long ‘I can wait an hour.'
