The stairwell smelled of iron and cold rain, and beneath that, faintly, of burnt sugar. Detective Harlow Quinn noted the smell the way she noted everything: filed, dated, set aside for later. She went down the spiral steps of South Kentish Town station with one gloved hand skimming the tiled wall, counting treads out of habit — ninety-four to the platform level, the same as any deep-line station of that vintage, though this one had been dark since 1924. The bulbs the forensic team had strung swayed on their cable and threw her shadow up the curve of the wall, long and then short, long and then short, like something following her that couldn't keep pace. At the bottom the passage opened into a cross-tunnel, and the tunnel opened onto the platform, and there was DS Tom Ferris standing in the middle of it with his notebook out and his coat too good for the job. "Ma'am." He looked pleased with himself, which meant he had a theory. "You'll want your torch. Lighting's rubbish past the tenth metre." "What have we got?" "Male, late fifties, no ID. Found by a track-inspection crew at ten past six — they came through the connecting shaft from the running tunnel, saw the light of the candles, called it in." He turned a page. "Cause of death, doc's guessing sharp force, left side, low. She'll say more when she's got him on a table. Probably eight to twelve hours." Quinn switched on her torch and let the beam walk down the platform. The body lay two-thirds of the way along, on its back, one arm flung out toward the tunnel mouth. The pathologist had rolled her kit onto a plastic sheet and was crouched beside it, humming. Around the man, in a loose arc perhaps four metres across, the platform floor was clean. Not swept clean — *scoured*. Beyond that arc the dust lay a full century thick, grey as flour, banked in soft dunes against the wall where the old advertising panels still hung. "Rough sleepers," Ferris said, following her look. "Or urban explorers, the ones who film themselves. Candles, look. They come down here for the atmosphere, they bring drink or something stronger, it goes wrong, one of them puts a knife in another and the rest scarper. Happens twice a year on the Northern line, honest to God. There's a whole forum." "Mm," said Quinn. She walked the edge of the clean arc without crossing it and squaton her heels at its border, elbows on her knees, and looked at the dust. Footprints. Hundreds of them. Not the confusion of a scuffle, not four or five men milling — hundreds, overlapping, deep, layer upon layer, tracking in from the passage she'd just come down and spreading out along the platform in both directions before ending at the wall. She counted eleven distinct tread patterns in one square foot before she stopped counting because it was pointless. Boots. Bare feet. Something with a narrow hoof-hard edge that she chose, for now, not to think about. A child's trainer, size ten or eleven, the tread worn to a smooth heel. "Ferris. How many people at your party?" "Sorry?" "How many people. In your gone-wrong drinking session." He came and stood beside her and shone his own torch down and she watched him try to fit what he was seeing into the shape he had already built. She had done the same thing herself for eighteen years. It was the most human instinct there was, and it had cost her more than she liked to itemise. "Foot traffic builds up," he said. "Over months. Years." "In a sealed station." "It's not sealed, though, is it, ma'am, there's the shaft—" "There's a shaft with a locked grille that Network Rail's own crew needed a key for, and the surface entrance has been a mattress shop since 1927." She stood, knees popping. "Look at the depth of the impressions and then look at the dust that's settled inside them. Which is none. Not a film. Nothing. Every one of these prints was made in the last two or three days." Ferris was quiet. "And they all go the same way." She swept the torch along the wall, forty feet of glazed cream tile and the ghost of an old poster — LEWIS'S FOR VALUE, the lettering unfaded, absurdly fresh in the beam — and stopped at a blank stretch between two tiled pilasters. "In from the passage. Along the platform. And they end there." "That's a wall." "I'm aware it's a wall." She crossed the clean arc then, stepping on the plates the SOCOs had laid, and went to it. Put her palm flat against the tile. It was warm. Not warm like a body, not warm like machinery; warm like a stone that had been sitting in the sun, in a place that had not seen the sun in a hundred years. She took her hand back and looked at the print her glove had left in the dust that wasn't there. "The candles," she said. "Nineteen of them." Ferris flipped back a page, glad to be useful. "Tallow, doc reckons, not paraffin. Set in a ring." "Not a ring." Quinn traced the wax stubs with her torch beam. "Two rows. Nine and nine, with the odd one at the head. That's not atmosphere, Ferris, that's a stall. Somebody was selling something and those candles were their light and the boundary of their pitch. The clean floor's the same — that's the footprint of something that stood here for hours and then went, and took its dust with it." "Took its—" "Two nights ago was the full moon." She said it before she could decide not to. Ferris laughed, uncertain. "You've been on the nights too long, ma'am." Quinn didn't answer. She had knelt beside the dead man. Fifties, as Ferris said, with a broad grey face and hands like paddles, the nails torn. His shoes were the interesting thing. The soles had been walked down to paper, worn through at the ball of the foot in a way that took years — and the uppers were spotless. Not a mark. Not a smear of the grey century that lay six inches to either side of him. She lifted the outflung hand with two fingers and turned it. In the palm, pressed so hard into the flesh that it had left a livid oval when she took it, lay a piece of bone the size of a domino, drilled through at one end, incised with a mark she had seen once before on an evidence bag she had signed for three years ago and never seen again. Her mouth went dry. She heard her own voice, quite level, say, "Bag this separately. Not with the personal effects. Separately, and it comes to me." His coat pockets held eleven pounds in coins, a receipt for nothing legible, and a small brass compass, its casing green-crusted with verdigris, its face etched with markings that were not points of the compass at all. The needle was not pointing north. Quinn knew where north was — she'd been counting steps and turns since the mattress shop's back stair, the way DS Morris had taught her. North was over her left shoulder, up the platform, toward Kentish Town. The needle pointed at the warm wall. She turned the compass in her hands, and turned it again, and walked six paces, and the needle swung and held like a dog that has heard its name. "Ma'am," Ferris said, from a way off, in the voice people used when they wanted her to come back to the version of the world they could stand in. "It's a curiosity shop compass. Broken. It's *broken*, that's all." "Yes," Quinn said. "That'll be it." She slipped it into an evidence bag, and did not label it, and put it in her inside pocket. Then she stood and turned toward the passage — and saw, at the top of the first flight, past the tape and the constable and the huddle of gawpers who had somehow found their way down a stair that did not officially exist, a small red-haired woman in round glasses with a leather satchel dragging at her shoulder. She was not looking at the body. Everyone looked at the body. She was looking at the wall, and tucking her hair behind her left ear, and her lips were moving, counting candles. "Ferris," Quinn said quietly. "Don't let that one leave."
