AI ‘Careful where your knees go, guv. That dust is evidence.’
Quinn put her knee exactly where she wanted it. The platform hadn't seen a train since 1924, but someone had swept it recently enough that her weight lifted a grey ghost of it into her torch beam. The tiles along the wall spelled SOUTH KENTISH TOWN in cracked white, the letters half swallowed by damp, and the air tasted of cold iron and, faintly, of hot wax.
Fenwick stood at the platform edge with his hands in his pockets, working a toothpick around his back teeth. He'd been on the job longer than she had and dressed like it: a shirt the colour of weak tea and a tie with a stain shaped like Denmark.
‘Who found him?’
‘Night crew from the demolition survey. Checking for voids before they pour anything.’ He nodded at the tunnel mouth, a black throat that swallowed her torchlight twelve feet in. ‘Gave me a statement each. None of them came past the ticket hall till they'd had a radio argument about it. Took them ten minutes to agree who'd walk down first.’
‘And the body was just here.’
‘Sat against the tiles, he said. Head down. Like a fella asleep on a night bus.’
‘Then he's been moved.’ Quinn's beam crawled the dust. She traced a bright, clean rectangle at the base of the wall, its edges sharp as a ruled line, and beside it four small round dents in a square. Chair legs. A trestle. She swung the light further along, and the dust gave her more of it: a clean mosaic of shapes on a floor untouched for a century, a ghost map of tables and stalls and walkways, all of it laid over the grime as if a crowd had stood here for a few hours and then the crowd had been lifted away by a hand.
‘Moved by who?’
‘By nobody who used those stairs.’ She pointed her chin at the dust. ‘Look at the footprints. Every set of prints stops short of that wall, right where the stalls were. And there's no prints coming out of the tunnel. Only the survey crew's going in, and those are all present and accounted for, standing round the kettle in the ticket hall and smoking where they shouldn't. So how did he arrive?’
Fenwick crouched, knees announcing themselves, and squinted at the floor. ‘Kids. Urban explorer crowd. They get down here on the old District passage, makes a night of it, phones, torches, the lot. Then the money runs out and the pills come out, and one of them-’ He turned his palm over. ‘You know how it goes.’
‘I know how it goes.’
‘Ambulance isn't going to come down the tunnel, is it? So his mates panic, leave him, or they carry him this far and go. It's a sad, small story, Harlow. I've written it forty times.’
Quinn walked the perimeter of the clean rectangle with her light low, and her beam found the thing the survey crew hadn't stood on: a ring of wax, eight of them, each the size of a bottle cap, each with a blackened wick, arranged in a circle eight feet wide. Inside the circle, chalk. Most of it scuffed to nothing by the heels of the departing crowd, but at the north edge, where a fallen tile had shielded the floor, the marks survived: a shape like a ladder cut in half, letters that weren't letters.
‘Forty stories and none of them had candles,’ she said.
‘Romantic urban explorers.’
‘Romantic urban explorers don't own a hundred candles and a cashmere coat.’ She thumbed the victim's lapel. Grey, single-breasted, hand-finished. ‘Costs more than the deposit on my flat. So does the watch.’ She lifted his left wrist and turned the dial to the light. The glass had clouded, and behind it both hands stood fixed at twenty past four. ‘Stopped. But it's not broken. That's magnetic . Someone put something against this after he was dead. Or it was near something big enough to do it on its own.’
Fenwick straightened and dusted his hands on his trousers. ‘Doctor says no wounds but a bump on the back of the skull, consistent with a fall, and a liver temp that puts him at four hours dead. Bruises on his wrists and ankles, but he's come off a skateboard or been in a scuffle, haven't we all. There's nothing here.’
‘There's a great deal here.’
‘Then tell me.’
Quinn stood up. She took her time, because time was what everyone else had wasted.
‘He's been shaved this morning,’ she said. ‘Clean cloth, clean nails, hair combed with something wet. And there's a nick under his jaw, scabbed over, so that nick is older than today's shave. Which means today's shave was done by someone else, after the nick. A barber, or a caller. Either way it wasn't a man sleeping rough in a tunnel.’ She crouched again at the shoulders. ‘No dust on his shoulders or his collar. Dust in his cuffs and down the front of his shirt. He was laid on his back and dragged by the wrists, and someone put a knee in the grime and then brushed him down. Watching his hands while he did it, so the top stayed clean. Careful, not frightened. This was tidy work.’
‘Tidy.’ Fenwick said the word like he could taste it.
‘And then there's this.’ Quinn teased a cord out from under the victim's collar. A knucklebone, drilled through and threaded, yellowed, the joint scraped clean of everything but a stain that looked like old ink . She set it in an evidence bag and held it to her torch, and her skin crawled a little at the weight of it. ‘Not a pendant. Not jewellery. This has been held a great deal, thumbed smooth on one side. A token. Money, maybe. Somebody paid his way in, or he paid somebody else's.’
‘Paid his way into a shut Tube station in Camden.’
‘The stairs behind us have a chain on them, and that chain has been cut, and the cut is fresh. Someone's been coming and going here for weeks without a torch, because the only torch marks on the floor are the crew's from tonight. He came down the dark like he knew the way. So did a hundred other people, and they all left at the same time, walking out of the dust without leaving prints.’ She straightened her back. ‘It's not the tunnel that's odd, Fenwick. It's that the crowd never passed through it.’
The wind moved behind them. Quinn had been in the tunnels long enough to know the draughts of the Northern line, the slow push and pull at the doors, the hot breath of the trains two hundred metres through the rock, but this came from the tunnel mouth, out of the black, and it brought a smell she'd caught at the stairs and couldn't place then. Myrrh and hot metal. Fruit left too long in a warm room.
Fenwick's toothpick stopped moving.
In her bag, something clicked. Small and insistent, like a beetle against glass.
Quinn opened the flap and took out the brass compass she'd lifted from the victim's coat pocket half an hour ago, its casing scuffed green with verdigris, its face etched with marks that were nearly the chalk marks and not quite . She'd turned it over twice and dropped it in a bag without looking closer, because it had seemed like a prop, a toy a rich man carried to feel clever. The needle inside it swung like a trapped fly.
‘That's north-north-west as far as I can tell,’ Fenwick said.
‘It's east.’ She held it flat. The needle corrected itself, spun a quarter turn, and held. ‘The tunnel's east. And it's a compass that doesn't want to be a compass, so what does it want?’
The hatches of her torch dimmed. Once, twice, the beam brown at the edges and then gone, and the darkness came down on them both so fast that Fenwick's hand found her sleeve like a child's.
Far down the tunnel, past the dead signal, something scraped along the rails and stopped. Then a match struck, bright as a coin, and another, and another, and the black mouth of the tunnel filled with a line of small flames coming on one after the other, hundreds of them, walking towards her.
