The platform tiles still bore the ghost of their original cream and green, though decades of grime had dulled them to the color of old teeth. Detective Harlow Quinn ducked under the police tape strung between two rusted pillars and let her eyes adjust to the portable floodlights her team had set up along the disused platform edge. The abandoned station beneath Camden smelled of standing water and something else — copper, maybe, or burnt sugar. She couldn't place it. "Watch the third rail housing," Sergeant Osei called from further down the platform. "Power's been cut since the sixties, but someone's run cables through here." Quinn stepped over a bundle of insulated wire that snaked across the platform and disappeared into the tunnel mouth. Her worn leather watch caught the floodlight as she checked the time. Quarter past two in the morning. She'd been asleep forty minutes before the call came. The body lay at the far end of the platform, near what had once been the station master's office. A man, mid-fifties, dressed in a tweed coat that looked expensive enough to belong in Mayfair rather than twenty meters beneath Camden High Street. He was on his back with his arms at his sides, palms up, fingers curled inward like a man catching rain. No visible wounds. No blood. His expression was the problem — not pain, not fear, but something Quinn had seen only once before. Awe. A dead man's face frozen in wonder. She crouched beside the body and pulled on a nitrile glove. The overhead fluorescents her team had rigged cast everything in a flat, surgical white that stripped the scene of shadow. She preferred shadow. Shadow told you where things were hiding. "Pathologist gives preliminary cause as cardiac arrest," Osei said, appearing at her shoulder with his tablet. He was young, thorough, and far too willing to accept the first answer. "No signs of struggle, no defensive wounds. Wallet's still in his jacket — Marcus Hale, fifty-three, address in Belgravia. Six hundred quid in cash, untouched." "So a rich man in a tweed coat suffered a heart attack in an abandoned Tube station at God-knows-when, and nobody robbed him." "Stranger things, ma'am." Quinn didn't answer. She lifted Hale's left hand. The fingertips were stained dark, almost black, but not with ink. The discoloration started at the nailbed and faded in a gradient toward the second knuckle, as though he'd dipped his fingers in something that had wicked upward through the skin. She raised the hand closer to the light. The staining had a faint iridescence to it, like petrol on wet asphalt. "What did the pathologist make of this?" Osei leaned in. "Mentioned it. Said it could be chemical exposure. They'll run tox when they get him on the table." Quinn set the hand down and turned her attention to the floor around the body. The platform had collected decades of dust and debris — broken tiles, pigeon feathers, the dessicated husk of a rat — but in the immediate vicinity of the corpse, the dust had been disturbed in a pattern. Not footprints. The disturbance radiated outward from the body in concentric rings, like ripples in a pond that had been frozen mid-expansion. She stood and backed up three paces to see it more clearly. "Get forensics to photograph this from above. I want the full radius of these markings." "Markings?" She pointed. Osei squinted, shifted, then she watched the recognition land on his face. "Could be from the paramedics," he offered. "They were first on scene." "Paramedics don't walk in perfect circles." She left him to arrange the photographs and moved toward the station master's office. The door was gone — had been gone for years by the look of the hinges, which were scabbed with rust — and the room beyond had been converted into something that made Quinn stop at the threshold. Stalls. Or what remained of them. Wooden trestle tables lined the walls, most collapsed or overturned. Fabric canopies in deep jewel tones — amethyst, sapphire, a red so dark it was nearly black — hung from hooks driven into the ceiling. Some had been torn down and lay in heaps. Glass jars littered the floor, most shattered, their contents reduced to stains and residue. A few remained intact on a shelf bolted to the far wall, and Quinn crossed the room to examine them. The jars held liquids of varying opacity and color. One appeared to contain moths suspended in amber fluid, their wings spread and motionless, preserved in positions of flight. Another held what looked like mercury, but it moved against gravity, climbing the interior walls of the jar in slow, deliberate tendrils. She didn't touch it. The whole room had the atmosphere of a bazaar packed up in panic. Quinn turned slowly, cataloging. A wooden crate in the corner held dozens of small objects wrapped in cloth. She knelt and unwrapped one. A brass compass, no larger than a pocket watch, its casing blooming with verdigris. The face was etched with symbols she didn't recognize — not any alphabet she'd encountered in eighteen years of forgery cases, smuggling rings, or organized crime. She held it flat in her palm. The needle swung, then steadied, pointing not north but toward the tunnel mouth behind her. She rotated ninety degrees. The needle followed, maintaining its bearing on the tunnel. Quinn wrapped the compass back in its cloth and stood. She pulled out her phone and photographed the room in methodical sections — walls, floor, ceiling, each table, each jar. "Ma'am?" Osei was at the doorway, tablet pressed against his chest. His face had changed. The professional ease was gone. "What is this place?" "That's what we're going to find out." She stepped past him and back onto the platform. "Who called it in?" "Anonymous. Burner phone. Caller said there was a body in the old station and gave specific directions to the access point through the Camden Lock basement." "Someone wanted us to find him." "Or wanted to do the right thing." "The right thing would have been calling 999 and staying on the line. This person knew the location of a hidden entrance to a station that doesn't appear on any current TfL map. They knew exactly where the body was. They called, gave directions, and vanished. That's not civic duty, Osei. That's stage management." She walked back to the body. Crouched again. This time she opened the tweed coat and checked the interior pockets. In the breast pocket, her fingers found a small disc the size of a two-pound coin. She drew it out. Bone — off-white, smooth, slightly warm to the touch. One side bore a symbol that matched the script on the compass face. The other side was blank. "What's that, then?" Osei asked. Quinn turned the disc in the floodlight. "Looks like a token. Some kind of pass." "For what?" She glanced back at the room full of stalls and jars and impossible mercury. "For entry." She sealed the bone token in an evidence bag, but her mind was already running. A wealthy man from Belgravia comes to a hidden market beneath Camden. He carries a token that grants him access. Something happens — something that freezes a look of awe on his face and stops his heart. The market clears out. Someone calls the police and leads them straight to the body, but not before the vendors pack up. Except they didn't pack up cleanly. They left product behind. They left the stalls. They left in a rush. Quinn stood and looked at the concentric rings in the dust around the body. Something had radiated outward from Marcus Hale — or inward toward him. The paramedics hadn't made those marks. Neither had anyone walking. The pattern was too uniform, too symmetrical. It looked like the aftermath of a shockwave, the kind left in snow or sand after a detonation, but there was no blast damage, no char, no debris pattern consistent with an explosion. "Osei. The caller. Male or female?" He checked his tablet. "Female. Young, dispatch said. Sounded frightened." Quinn filed that. She walked the full length of the platform, scanning the ground. Near the entrance — a steel door that opened onto a narrow staircase leading up to the Camden Lock basement — she found a book. Leather-bound, small enough to fit in a coat pocket. It had been dropped rather than placed, lying face-down and splayed open. She picked it up and turned it over. The cover bore no title. Inside, the pages were covered in dense handwritten notes in two different hands. One wrote in English, a cramped academic script. The other wrote in the same unknown symbols that appeared on the compass and the bone token. Between the pages, someone had pressed a sprig of dried rosemary. It crumbled when she opened to that page. The English notes referenced something called "rift instability" and mentioned coordinates that could have been map references. One passage, underlined twice, read: *The alignment is accelerating. HM insists on attending the next opening despite the readings. I've told him the compass activity alone should be enough to postpone, but he won't hear it.* HM. Hale, Marcus. Quinn closed the book and bagged it. She walked back to the body and stood over it, looking down at the face caught in its final expression. Three years ago, her partner DS Morris had worn a similar look. Not identical — Morris's eyes had been open, and they'd carried something closer to terror than wonder — but the same fundamental quality. The look of someone who had seen something the human face wasn't built to process. The pathologist had ruled Morris's death a stroke. Quinn had accepted it at the time because accepting it was easier than the alternative, which was admitting that the marks on the floor of that warehouse in Deptford — concentric, radiating, perfectly symmetrical — had no rational explanation. She looked at the rings in the dust around Marcus Hale. "Osei. Pull everything we have on Hale. Financial records, travel, known associates. I want to know every place this man has been in the last six months." "Cardiac arrest, ma'am. If the pathologist confirms it—" "The pathologist is going to confirm that his heart stopped. I don't dispute that his heart stopped. I'm interested in what stopped it." She pulled off the nitrile glove and shoved it in her pocket. "A man doesn't come to a place like this to have a heart attack. He came here to buy something, or sell something, or see something. Whatever it was, it killed him. And someone who knew exactly what happened wanted us standing here looking at it." "You think we're being played?" Quinn looked at the room of stalls, the jars of impossible things, the compass that didn't point north. The bone token in its evidence bag felt like it was generating its own gravity in her coat pocket. "I think someone opened a door they couldn't close. And now they need help they can't ask for directly." She turned toward the exit, her footsteps precise and measured against the old platform tiles. Behind her, the floodlights hummed, casting the scene in their flat, honest light. But Quinn had noticed something the lights couldn't reveal — the shadow under the nearest trestle table fell in the wrong direction. Away from the light source, where it should have stretched toward the wall, it reached instead toward the tunnel mouth. Toward whatever the compass needle pointed at. She stopped. Looked at it for a long, still moment. Then she kept walking.
