By the third flight of stairs, Quinn's torch had gone the colour of weak tea. She tapped it against her palm. The beam rallied, then shrank to a thread. Below, in the ticket hall, Doyle had planted his own torch upright on the floor, and its cone lit the ceiling tiles from beneath — the green of old bottle glass, flaked with ninety years of damp. Hawley Crescent station had closed in 1934. The dark down here had had time to settle. "Guv." Doyle worked his gum, hands in the pockets of his suit jacket. "You're going to love this one." "Give it to me." "Anonymous call, ten past four. Woman's voice. Said there's a body on the platform at Hawley Crescent, then hung up before the operator got a name. Uniform came in through the maintenance door on the alley. Street gate's rusted solid — nobody's opened it since the war." "And the caller knew he was here how?" "That's the bit you'll love." He nodded down the passage. "Come and see." The body lay at the centre of the platform, on its back, arms arranged along its sides. Male, mid-thirties. A wool coat that cost real money, clean shoes, manicured nails. Wrong, all of it, for a squat or a squatters' party. Dr Banerji crouched beside him with her kit open. "Morning, Detective. No wounds. No puncture sites, no ligature marks, no petechiae. His heart stopped. That's what I have until the post-mortem." "Time?" "Between eleven and two, going by temperature and rigor. Lividity's fixed on his back. He died where he lies — nobody moved him after." Quinn circled the body at two metres, torch raised. The dimming beam caught pools of candle wax at regular intervals along both platforms, and beneath the dust, rectangles scuffed clean — rows of them, in lanes, the length of the station. Chalk lines marked the corners of each. "Rave." Doyle spread his hands. "Or a buy. Dealers set up tables, punters come down, something goes wrong for this one. They bolt, he stays. Happens." "Count the cans, Aaron." "What?" "Cans. Bottles. Fag ends. Needles. Vomit in the corners. Find me one." She walked the nearest lane, slow, reading the floor. "A hundred people stood down here for hours. I've policed raves in warehouses, in fields, in a drained lido. They all leave a skin. This lot left nothing. Not a crisp packet." "Maybe they were tidy." "Dealers don't chalk their pitches and light them with candles." A SOCO named Lena looked up from the threshold of the ticket hall, swab in hand. "Detective. The lines across the doorways. I've tested twice. It's salt. Just salt." "Salt at every entrance," Quinn said. "Ritual lot, then." Doyle shrugged. "Occult-themed party. Camden's full of them." Quinn's torch guttered. She checked her watch out of habit — the leather strap had gone soft and dark with years of wear, and the mechanical hands ticked on, unbothered. Doyle saw the gesture and pulled out his own phone. "Dead. Thirty-four per cent when I came down. Yours?" "Watch is wound, not wired." She turned the thought over. "Whatever's flattening batteries down here has no taste for springs." "Cheap torches, guv." She walked to the stairs instead of answering. The dust on the steps held prints in plenty — dozens of sets, overlapping, all sizes. She crouched. Turned. Looked up the flight, then down, and felt the shape of it before the words came. "Lena. Photograph the stairs, every tread. Then tell me how many prints go up." Ten minutes later Lena came back with her camera screen held out and her mouth set in a line. "Down only. I count ninety, maybe a hundred distinct treads descending. Nothing ascends. Not one." "Service tunnel." Doyle was already moving. "Track level. They went out along the line." They followed him along the trackbed — a dry canal of soot where the rails had been lifted decades before — to the tunnel mouth. Victorian brick sealed it, black with old smoke, the mortar crusted. Cobwebs sagged across an inspection hatch, grey and unbroken. "Bricked up in the fifties," Lena said. "Soot's intact. Nothing's gone through there since." Doyle's jaw worked the gum harder. Back on the platform, Quinn knelt by the body and lifted the cord around the dead man's neck. A disc hung from it — bone, thumb-width, polished by handling, carved with a mark: a keyhole inside a spiral. Three years since Morris. His notebook had carried a page of that same mark, copied over and over in his cramped hand, the page he never explained to anyone. She'd memorised it without meaning to, the way the mind keeps what a case leaves open. She set the disc down and stood before the memory could take hold. In his coat pocket she found the compass. Brass, small enough to vanish in a fist, its casing furred with verdigris, the face etched with sigils too fine for machine work. She held it level. The needle pointed down the platform. "North's that way." Doyle pointed the opposite direction. "I know where north is." She turned a full circle, slow. The needle swung with her and settled, every time, on the bricked arch at the platform's end. She walked it back to the body. Over the dead man, the needle lost its purpose and wandered in loose circles. Ten steps away, it snapped back to the arch. "Magnet in the brickwork. Old ironwork in the walls. It's a prop, guv. A toy from one of the stalls." "Then it'll point at any iron." She held it over the trackbed, over Banerji's steel kit case, over Doyle's belt buckle. The needle ignored all of it. It wanted the wall. Lena called from the far lane, voice pitched careful, the way people speak when the floor has just shifted. "Detective. You should see the overlay." The photographs told it in sequence. The scuffed lanes between the pitches crossed and re-crossed — and where the lanes reached the centre of the platform, they bent. A clean arc around one fixed point, trodden by dozens of feet, over and over, through the whole shape of the night. "The lanes cut across the earlier prints," Lena said. "The crowd walked this way for hours. They walked around something. Around him." Doyle stared at the screen, then at the body, then back. "He died after they left. Midnight, Banerji said. Market packed up at eleven." "Lividity says he never moved. He lay here, dying or dead, at the centre of a working market, and ninety people stepped around him like he was a pillar box." Quinn let that sit. "Nobody helped him. Nobody ran. The stalls traded on, and when it was over, they took their tables, their stock, their litter, every trace of themselves — and left him." "All right." Doyle's voice had lost the gum-chewing ease. "Say it was a market. Ninety-odd people come down those stairs. Nobody goes back up. The tunnel's bricked. The gate's rusted shut. Where did they go?" Quinn walked to the arch. The brick stood solid, soot-black, undisturbed, the cobwebs whole. She raised the compass. The needle held true on the wall, steady as a blade, and would not be moved. "They didn't go up, Aaron. Ninety people. Check the tread count again if you like." "People don't walk through walls." "No." The sigils on the compass face caught the last of her torchlight, and the needle did not waver. "So between the bottom of those stairs and this wall, there's a door. Find it."
