'Oh, very funny,' said Bimsley, squeezing into the space. Reaction-gap reduction was a training initiative long touted by the Met to its forces, and was consequently the butt of many jokes. The idea of crime anticipation and prevention was hardly new and not overly successful, but it was well suited to the PCU. At least, At least, thought May, thought May, we should be able to manage an arising situation between a convicted fraudster and an easily duped academic. we should be able to manage an arising situation between a convicted fraudster and an easily duped academic.

'Do you think I can get an advance on my wages?' asked Bimsley. 'I'm broke.'

'You're supposed to be,' replied May. 'You're a junior.'

'Yeah, but I'm working overtime.'

'I'll give you one if you find something.' May shone the torch ahead. The tiles were covered in the kind of calcified slime he associated with river walls at low tide. 'It looks like you can get all the way down there,' he encouraged. 'Take my Valiant.'

Bimsley accepted the torch. 'If I ruin my clothes, I'm going to put in a chit.' He tried to avoid touching the walls, but couldn't help it after something sleek and squeaking ran across his boots. His palm came away green.

'What's that on your right?' called May. 'Down by your boot.'

Bimsley lowered the Valiant. 'I can't see anything,' he called back.

May had spotted the pale keystone of an arch, and a stone known as a voussoir, voussoir, part of a curving cornice, mostly obscured by rubble. 'Pull some of that rubbish away, can you?' part of a curving cornice, mostly obscured by rubble. 'Pull some of that rubbish away, can you?'

Grimacing, Bimsley plunged his hands into the pile and dragged back a rotted mattress. It took him several minutes to remove the panels of wood and piles of brick that had silted up against the top of the underground arch, which he saw was staked with iron bars at six-inch intervals. He shone his torch inside. 'Looks like it goes a long way back,' he called. 'No way of getting in there without cutters.'

'If we can't gain entrance, that means Greenwood hasn't been able to get inside, either. They've probably only just taken the warehouse wall down. That means we're still in time.'

'Yeah, but in time for what?' Bimsley pressed his face against the rusted bars, lowering the torch.

'Nothing at all?'

'Nope.'

'Let's go.' May began stepping back through the debris.

'Hang on.' Bimsley crouched as low as the gap permitted. 'Stinks down here. I think I can see . . .'

He turned around, flashing his torch along the gap, but May had already disappeared from view. Shining the beam through the bars, he could make out a curving brick wall with weeds protruding from it. At the bottom, below a deep ridge, was a thread of glittering silver.

'I think there's water, if that's what you're-Mr May?' The circle of light dropped lower, picking up another reflection. Bimsley pushed himself closer and found one of the bars loose. It jiggled in its concrete setting, then dropped down several inches. After a minute or so of further bullying, he was able to remove it completely. The resulting hole was wide enough to ease his head and shoulder through. He raised the torch again.

He nearly overlooked it because it failed to reflect the beam, but the light picked up something against the wall, a coil of tiny wooden beads fastened together with a strip of leather. Pushing his bulk flat against the bars, he was just able to raise the strand in his fingers.

But now there were two reflections of light above the bracelet, like small gold coins, bright and flat. It took him a moment to work out that they were eyes, and by that time he had heard the throaty rumble of a growl.

The dog attacked before he could unwedge himself. It leapt at him, spraying spittle, its jaws desperately snapping shut on his shoulder, biting down hard, its teeth clamping together through the generous padding. Bimsley cried out and fell back as the material tore, and the rottweiler launched itself into the gap. It got halfway through and stuck, wriggling back and forth with its hind legs off the ground until it twisted sideways, falling back into the cavernous cellar.

He could hear it trying to breach the space again, barking frantically, maddened by its imprisonment, as he stumbled over the chinking bricks toward the alley and the exit.

Back on the street, Bimsley examined the damage to his jacket. 'Bloody dog-must be another way in.' He poked the torn material back in place, then remembered the bracelet. 'Here, this qualify me for an advance?'

'I don't know-let me see.' May raised it to the light and gingerly sniffed. Sandalwood, he thought, santalum album, santalum album, a popular item of cheap jewellery for those on the hippie trail; the cloying smell stayed for years. A flat bone medallion hung in the centre, an intricate design he couldn't decipher without his reading glasses, which were back at the unit. He slipped the bracelet into his pocket as Bimsley limped along behind him before departing for the West End, still complaining about his ruined clothes. a popular item of cheap jewellery for those on the hippie trail; the cloying smell stayed for years.

'He was shaken, but fine,' May told his partner the following morning. 'The dog's teeth just grazed his skin, but I sent him for a tetanus shot all the same, and he's going to charge us for the jacket. You think Greenwood put the dog in there? I can get the RSPCA down now.'

'No, don't do that.' Bryant was sitting on a pile of encyclopedias, taping together a set of surveyor's maps. 'I don't want anything to alert him. Look at this.' He waved the tape roll over the far side of the map. 'That blue line I've marked out is the Fleet. It discharges into the river via a bricked tunnel beneath Blackfriars Bridge, at the very point where Roberto Calvi's body was found on 17 June 1982. He was a senior banker, if you recall, a member of the Italian Masonic lodge P-2. He was discovered hanging there, just about the most unlikely suicide London has ever seen. He'd lost a fortune as the chairman of the Banco Ambrosiano, owing something like 1.2 billion dollars. The money had been siphoned off and hidden from the IOR, the Vatican bank. Blackfriars Bridge has historic connections with the Freemasons, and it looked as though his assassins were deliberately leaving a warning to others, although the official verdict was still suicide. After continuing pressure to reopen the case, the body was exhumed in '92 and was found to exhibit clear evidence of murder. Five years later, prosecutors in Rome indicted four Mafia members. They belonged to the Banda della Magliana, Banda della Magliana, not the kind of people you want to mess around with. The inference that the Vatican hired hitmen to punish their embezzler is unthinkable to the devout, but not beyond the realms of possibility to the rest of us.' not the kind of people you want to mess around with. The inference that the Vatican hired hitmen to punish their embezzler is unthinkable to the devout, but not beyond the realms of possibility to the rest of us.'

'You amaze me,' May marvelled. 'Considering you can't remember your PIN number or where you've left your glasses.'

'This is work,' Bryant retorted, adjusting his spectacles. 'Oh, and I've read up some more on underground rivers. Did you know that in 1909 the Hippodrome Music Hall in Charing Cross Road staged a water spectacle called "The Arctic"? They built icebergs and placed fifteen polar bears in a giant tank. Guess where they got the water for the display? The Cranbourne, the ancient river that runs right underneath the building. And of course we know that there's an artesian well beneath the Palace Theatre, because you nearly fell down it once. It seems there are entrances and exits to rivers all over London. Listen to this.' He raised a leatherbound book and adjusted his reading glasses. ' "Until 1960, the garden of 20, Queen Square, Bloomsbury, WC1 contained a trapdoor and steps leading to the stone tunnels of a stream known as the Devil's Conduit." And there are dozens of other examples. No wonder Ubeda needs to employ an expert like Greenwood as a tracker.'

'I have something to show you.' May rummaged in his pocket and produced the broken sandalwood bracelet. 'Bimsley found it. I thought you'd like to see.'

Bryant wrinkled his nose and held it away. 'Probably came from Camden Market. Where did you get it?'

'Our intrepid DC found it inside the sewer inlet, just before the dog attacked him. There's another way in, but we couldn't find it. I took your advice and let Bimsley handle the dangerous part.'

'Good. You know you're not supposed to do anything too strenuous,' Bryant admonished. 'Sooner or later you'll have to start acting your age.'

'If I did that, I'd never get out of a chair again. It may be nothing, but I thought I might send it to Banbury, see what he can get out of it.'

'Let me take a good look first.' Bryant's desk-lamp revealed a little more information about the panel on the bracelet, but he needed a spotlight to see it properly. Dragging an illuminated magnifying stand from beneath his desk, he set the bracelet underneath and studied it through the distorting glass.

'Oh, I think there's a penis.'

May looked surprised. 'I don't see that. Are you sure?'

'Quite sure. It's rather faint.' Bryant slid the bone panel under a sheet of paper and ran a pencil back and forth across the top. 'See it now?' He held up the rubbed sheet. 'It isn't just any penis, either. I've seen this before.' He had that knowing smile on his face that May had come to dread, the one that said, I know something you don't. I know something you don't.

'Go on, then. You're dying to tell me.'

'Look at the base. It's a penis that's not attached to a body. It's got wings-you can just make out the traces. See these tall flowers in the background-they're lotus leaves. And the other ones intertwined-that's papyrus.'

'What does that mean?'

'The lotus flower and the papyrus reed are the symbols of Lower and Upper Egypt. When they're tied together like this, a new meaning is created, an indication of unity and strength. These are very common symbols, especially when used in conjunction with river glyphs. Rivers feature strongly in Egyptian mythology because life springs from the waters of the Nile. But the penis . . .' He scratched thoughtfully at his unshaven chin. 'According to Plutarch, Osiris was killed by his evil brother Seth, who tricked him into climbing inside a coffin which he then cast into the sea. He later ripped the corpse into fourteen pieces and threw them into the Nile. Isis and her sister Nephthys found all the pieces except the phallus, which had been swallowed by a crocodile, and buried them. They gave new life to Osiris, who stayed in the underworld as its judge and ruler. The penis of Osiris is therefore a potent symbol of fertility and rebirth.'

'Very interesting. But does it have anything to do with Greenwood?'

'It's an Osiris bracelet representing death as a male and rebirth as a woman. It could simply mean the loss of the sun and the arrival of the moon, or any other great change. The flight symbolism is interesting. A winged penis was a Tudor icon used by the prostitutes of south London, specifically the ones working near the river between Blackfriars and Lambeth.'

'Is the bracelet old?'

'No, it's probably quite recent. Things like this are still sold all over the Upper Nile. The symbolism is clearly connected with the site of its discovery. The bracelet cord and clasp are unbroken; it didn't fall off someone's wrist.'

'I wonder why it was left there.'

'I think we can work that out, John. Old beliefs never die. There's hardly a building or thoroughfare in London that doesn't contain a token somewhere in or under its construction. A more interesting question is who who left it. We should congratulate Bimsley on his discovery.' Bryant pinned the bracelet on the wall behind his desk. 'While you were out in the field, Meera and I did a bit of research. The demolished building you entered was once the headquarters of Carolson Watchmakers, who bought it from a violin manufacturer. We know that violins were first produced from this address in 1835, which would lead me to believe that the building would be listed, despite being invisible from the road. But Meera checked with the council and it appears to be a legal demolition. The site has recently been purchased by a development company, and if Jackson Ubeda is involved, his name certainly doesn't appear on the company register. All we can really do is wait for Greenwood to return to the spot.' left it. We should congratulate Bimsley on his discovery.' Bryant pinned the bracelet on the wall behind his desk.

'Let's suppose he has a way of getting into the remaining Fleet tunnel,' May suggested. 'You said it doesn't pass beneath any important buildings on its way to the river, but you may be wrong. There's a discreet bank behind Ludgate Circus, a new one with smoked-glass windows and ram-raid-prevention bars, that deals with fund transfers from the Upper Nile. I think your first idea wasn't so barmy after all, Arthur. Jackson Ubeda was born in Tennessee, but according to his file he's of Egyptian extraction.'

'You think he's about to drop in on an old friend?'

'Or an enemy.' He helped Bryant gather up the maps. 'There's not a jot of evidence, of course, which means we'll have to hope that Greenwood decides to go spelunking while we can still afford to keep an eye on him.'

'I have a better idea,' said Bryant. 'Janice, would you step in here a moment?'

'You won't be able to bellow at me when they finally put a door on your office,' Longbright warned. 'What do you want?'

'Tell me, do you own any valuable jewellery?'

'On my salary? Don't be ridiculous.'

'Well, could we perhaps borrow some for a couple of hours?'

'You nearly got me fired the last time we raided the evidence room. Why?'

'I want you to become a wealthy Egyptian woman for about half an hour.'

Sergeant Longbright straightened her skirt and wondered if she had overdone the eye make-up. She knew that older married women in Cairo sported the look one saw all around the Mediterranean, gold sunglasses and bright boxy jackets, but she felt like a cross between Cleopatra and Dalida. She was wearing an ostentatious emerald necklace which Bryant had borrowed from a sealed evidence bag, much to Kershaw's horror. The waiting room of the Upper Nile Financial Services Group was a cool marble sarcophagus. Longbright seated herself between arrangements of dried flowers on plinths, like a bereaved relative waiting to view a corpse.

She had booked an appointment with the manager, Monsieur Edouard Assaad, explaining that she wished to transfer money from a town near the Sudanese border to an account in London, trusting that he would prefer to speak English rather than French or Arabic. To enter the building, she had been required to pass through a metal detector and have her bag examined, in line with the requirements of banking in Cairo. May specifically wanted to know about the building's vault, and she was considering how to angle the conversation when M. Assaad arrived.

He had agreed to meet with Longbright to reassure her that Upper Nile FSG was the secure and sensible choice for a woman of means. Small and almost absurdly neat, from his waxed black tonsure to his freshly polished Oxford toecaps, he shook her hand warmly and ushered her to a side-room lined with crimson tapestries and low cushions.

'I may also wish to deposit a number of valuable items with you,' Longbright explained as a small silver tray of mint tea arrived. 'Would that be possible?'

'It can certainly be arranged,' promised M. Assaad, supervising the ritual of pouring.

'I was given to understand that you have a vault here on the premises.'

'I'm afraid you have been misinformed, Madam. We primarily deal with electronic transactions, but if you wish, we will contact an affiliated company where space in a secure vault may be set aside for you.'

'Thank you.' She wondered if she had failed to observe the rules of formal hospitality, moving too quickly into the discussion of business. Like Bryant, Longbright had never been adept at small talk. 'I was recommended to you by an old friend of mine, Mr Jackson Ubeda. I assume he is a client of yours?'

'I am sure you would be the first to appreciate that we are unable to divulge the identities of our clients.' M. Assaad's gracious demeanour shifted slightly. Longbright could tell that she had made him suspicious. Or perhaps the mention of Ubeda's name had bothered him.

She decided to press on. 'Surely you do have some kind of underground storage facilities?'

'Alas, no. The lower-ground floors were filled in many years ago. There were apparently some problems with damp undermining the building.'

'That's right, an old river runs near your property.'

'So I have been told.' M. Assaad was clearly losing patience. 'Perhaps you would care to see our chief clerk, who will supply you with the appropriate documentation for your account.' He punched out a number, covering the mouthpiece while he waited for a reply. 'We have a great many friends and clients in Aswan-I am sure you will find our services invaluable.'

Well, that was bloody embarrassing, she thought as she waited for a bus in Farringdon Street. she thought as she waited for a bus in Farringdon Street. I know he saw right through me. I know he saw right through me. More problematic was the idea that the bank had no basement. It meant that Bryant's line of inquiry was misdirected, and as the matter was not an officially sanctioned case for the unit, it could not go much further. As soon as the Met's claim on the unit had ended, Raymond Land would be waiting to approve a number of new investigations for them, so there would be no more time to spend on pet projects.

First Ruth Singh and now this, she thought. she thought. The pair of them have only been back at work for a couple of weeks and they've already managed to set everyone's teeth on edge.

Still, she wondered how long they could continue to follow their own meandering path at the unit without being held accountable. The Home Office demanded results, and they would all have to face the consequences of failure.

RIVERWATCHING

Kallie was growing quite used to it now.

As she turned off the hot tap, the sound of running water continued, gurgling and churning somewhere under the floor. She tried to work out if it ran from the back of the house to the front, but there was no telling if what she could hear was a metre away, or ten. She had tackled Elliot Copeland at the party, telling him about her problems with the basement wiring. He had offered to take a look for her, but had so far failed to make good on the offer, forcing her to make do with the battery lamp. Paul had gone to the pub with Jake Avery, the TV producer from across the road, hoping to find out about job opportunities, while she had been left to do the laundry in Ruth Singh's decrepit washer-dryer.

And the house was starting to bother her.

The omnipresent sound of water, the damp patch growing in the wall and the return of the seemingly invincible spiders were minor causes for concern. She could manage without electricity until someone reliable could be found to repair the system. Even having to bury Heather's cat in her back garden had not fazed her-there was something far less tangible at work within these bricks. The attic echoed with rain, the pipes ticked and tapped with the passage of water, the floorboards stretched and bowed like the deck of a ship. Window frames, dry for so long, now expanded in the wet weather and refused to open or close.

Sometimes it felt as if a stranger's eyes were at her back, watching in silence as she moved about the basement. The sensation didn't occur in the front room or the bedrooms, even though they were the only ones which were overlooked. Something felt wrong inside the building: dead air displaced, events rearranged. It was nothing more than a vague sensation, but she had learned not to overlook such presentiments. She couldn't explain the feeling to herself, or articulate it to Paul, who had a habit of dismissing such ideas with an impatient wave of his hand. According to him she was simply not used to owning a house. More insultingly, he implied that using a room in which a woman had recently died would always be the source of some kind of female hysteria.

Then there was what she had come to think of as the Presence. After returning from the party two nights earlier, she'd felt sure that someone had been in the house. Nothing had been conspicuously moved, but the arrangement of items left out in the kitchen looked wrong to her, as though she was viewing them from a slightly altered perspective, as though the miasmic air within the closed rooms had kaleidoscoped, allowing the dust to drift gently and realign itself in alien patterns, like reordered synapses.

There had been another argument over money, this time because Paul had spent part of his redundancy pay on a laptop computer, when they had agreed to pool their earnings toward the refurbishment of the house. They had never fought this violently before, even when they were sleeping on Neil's sofa. It felt as though the house was siphoning off their happiness, allowing it to stream away beneath the cold bathroom floor.

At twenty past eleven she heard the front door open, and found Paul fighting to free himself from his jacket in the hall. 'I thought you'd be asleep by now,' he said, with the faint struggle for clarity in his voice that marked him as a man who had drunk more than his limit. 'Come and sit in the front room.'

He tugged at her until she sat beside him on the couch. 'I've been wanting to talk to you.'

'You're drunk, Paul.'

'Only a bit. I've just had a chance to think about you, and I can tell you're not happy.'

'Let's discuss this in the morning.'

'Suppose-' he raised his voice, 'suppose we had money in the bank, I mean a decent amount, enough to buy a new place.'

'What are you talking about?'

'I was in the pub with whatsname-Jake-he goes hang-gliding in France-'

'What's this about money? Did he offer you a job?'

Paul pressed the heel of his hand into his eye, concentrating. 'Jake hasn't got anything suitable at his company. He wants me to go hang-gliding with him, you remember I used to-'

'You can't make money from hang-gliding,' she told him. 'Come on, I'll get you to bed.'

'I can manage.' He rose unsteadily. 'Look at this place. We can do better-Jake was talking to the other guy, at the party-'
