Christopher Fowler - The Water Room

‘They wouldn’t do that. They approved the rebuilding programme in record time.’

‘It would have happened anyway, because this site is valuable police property. Have you heard talk about a new style of police shop for the Camden area?’

‘What do you mean?’

‘It’s one of the Home Office’s pet ideas, a drop-in community centre staffed by casually dressed officers who liaise with local community leaders. And it’ll sell products licensed to the Metropolitan Police, to interest the kiddies. That’s what they’re saying this place is going to become, some kind of Disney police store, just as soon as they’ve got us out.’

‘Raymond wasn’t happy about my involvement with Ruth Singh,’ reminded Bryant, ‘so we can hardly afford to have your lecturer-’

‘It took them just a few minutes, Arthur. Meera found something. Look.’ He flattened out the crumpled receipts. ‘Greenwood just spent several hundred pounds on climbing equipment- high-tech stuff.’

‘Perhaps he’s taken up mountaineering.’

‘Don’t be daft, he’s in his sixties and has a bronchial condition.’

‘Well, I don’t know. Is it really any business of yours?’

‘He has some specialist classified knowledge. The kind of knowledge that could be open to abuse.’

‘I thought he taught history.’

‘I was thinking of his particular field of interest. Rivers. Specifically, the underground rivers of London.’

Bryant’s interest was aroused. ‘That’s different. The culverts still run through very sensitive areas. Under Buckingham Palace, for example, and virtually under the Houses of Parliament.’

‘Really? I thought they had all dried up long ago.’

‘Not at all. The entire subject is open to misinterpretation, of course. It’s a murky area of London interest; not only are the size, geography and number of the city’s rivers up for dispute, but there is very little left to see, and no accurate way of comparing the present with the past. Consequently, one ends up tracking filthy dribbles of water between drains and across patches of waste ground.’

‘Then why bother studying them at all?’

‘Because just as the old hedgerows shaped our roads, so did the river beds. They created the form of London itself. They are the arteries from which its flesh grew.’

‘Since when were you an expert?’ asked May, surprised.

‘I was going to do an overground guide tour tracing the route of Counter’s Creek. That one’s followed by a mainline railway line all the way from Kensal Green to Olympia, Earl’s Court and the Thames. We studied quite a few, but abandoned the idea because of the difficulty of getting groups around the obstructions. The Westbourne river still surfaces as the Serpentine, you know. Many of the original river beds are mixed in with the Victorian sewer system now. There’s something undeniably magical about the unseen parts of the city, don’t you think? The roofs and sewers and sealed public buildings, the idea that a different map might emerge to chart previously unimagined landscapes.’

‘I agree up to a point. But if there’s nothing left of these rogue rivers, I don’t see why someone would pay my old rival for information about them.’

‘I didn’t say there was nothing left. Most of them were bricked in. The best-known missing river is the Fleet, which starts on Hampstead Heath, going down through Kentish Town, diverting past us to St Pancras, then to Clerkenwell and Holborn, and out to the Thames just past Bridewell. It was also known as the Holebourne, or the stream in the hollow. They used to say it was a river that turned into a brook, a ditch and finally a drain. The Smithfield butchers chucked cow carcasses into it, and it was used as a toilet and communal rubbish dump for centuries, so it kept silting up and becoming a public health hazard. I think it was finally bricked over in the mid 1800s, but that’s the point-most of the rivers ducked underground at various locations and were provided with brick tunnels, but that doesn’t mean they dried up. Look at the Tach Brook, for example. It’s still there, running underneath car parks and public buildings in Westminster. When I was a nipper, I used to climb down the viaduct and muck about beside the water that flowed out into the Thames from Millbank. Underground engineers still have to be wary of such channels, because they know their excavations could be destroyed by them.’

May pulled some papers from his drawer and threw them across the desk. ‘Monica gave me this. Apparently, Greenwood is our top underground man. He’s mapped them all out in his time, and that’s only a partial list.’

Bryant scanned the list of evocative names. The Westbourne, Parr’s Creek, the Roding, the Slade, the Tyburn, Mayes Brook, Hogsmill, the Crane, the Peck, the Ravensbourne, Hackney Brook, the Falcon, the Effra, the Neckinger, the Walbrook, the Wandle, dozens of other smaller tributaries.

‘They run from Hampstead to Acton to Bromley to Barking,’ May added.

‘What do you expect? The city’s in a basin and the water drains down.’ Bryant spelled it out as if talking to a particularly inattentive child. ‘River beds criss-cross the whole of London in a grid, around and underneath and sometimes even through some of the most sensitive buildings in the city. Some of them are connected to the sewers, which means they tap directly beneath government properties.’

‘Here’s the list of stuff Greenwood’s purchased so far. Monica found it in his jacket.’

Bryant dug out his reading glasses and examined the sheets. ‘This equipment is for climbing down, not up. Look at these items: high-powered torches, thigh-boots, pipe-clamps, hardly any ropes. This other receipt is a pharmaceutical treatment for rat bites. Looks like someone’s hired him to get into the remains of an underground river for some dubious purpose, possibly to enter private property.’

‘You think they might be planning to tunnel into the Bank of England, something like that? Wouldn’t it be rather an outmoded notion in these days of computerized security?’

‘Just because it hasn’t been attempted for a few years doesn’t mean it’s outmoded, John. Think about it; someone has searched out an expert in the field who has a blotted copybook, and is proposing a venture that involves purchasing safety harnesses and weighted boots. I’m not saying that your cuckold has any knowledge of his client’s real intentions, but he’s refusing to tell his wife because he doesn’t want to compromise her safety, which suggests he knows something.’

‘I was planning to confront him with the evidence and warn him off, you know, as a friend,’ said May.

‘You said yourself he’s not a friend, so why should he take your advice? Besides, I have a better solution.’

‘What might that be?’ asked May, dreading the answer.

‘We can find out what he’s up to, and stop him from doing it. It’s a clear security issue. Raymond would have no option but to sanction the case.’

‘Arthur, please don’t do anything that would get us into trouble. We don’t need it right now. We have to start playing by the book.’

Bryant’s rheumy blue eyes widened in innocent indignation. ‘I’m surprised at you, John. When have I ever got us into trouble?’

Kallie sanded and undercoated the front door before applying a rich indigo gloss to the wood. She had repainted the bedroom and put up some cheap curtains, working her way down a list of chores, but felt as if she had barely scratched the surface. She hadn’t lived in a house since her parents were together. She was crouched in the hall, trying to thump the lid back on the paint tin without crescenting her palms, when Heather walked past laden with shopping bags.
