Detective Harlow Quinn held her warrant card up to the constable at the top of the stairwell, her other hand already on the railing. The air coming up from below smelled of wet rust and something older—candle wax, maybe, and a sweet rot that reminded her of a church crypt. She checked her watch: 0317. The worn leather band had left a faint groove in her wrist over the years. She descended the stairs with her hand skimming the rail, counting steps out of habit. Eighteen years on the force, and she still counted exits. The stairwell was an abandoned Tube access, its tiles black with age, the metal steps shivering under her shoes. At the bottom, the station opened up. It should have been a platform, but someone had built a market inside it—stalls cobbled together from scaffolding planks and old doors, tarps strung between pillars. Some stalls were dark. Others were lit by oil lamps or jars of pale green light that Quinn couldn't identify. The place smelled of smoke and myrrh and unwashed wool. She noted the exits: the stairwell behind her, a service tunnel to her right, and at the far end, a boarded-up track tunnel. "Ma'am." DS Miles Calloway met her at the cordon line, a thin blue-and-white tape stretched across two stalls that looked ready to collapse. He was younger than her by a decade, eager in a way that made his voice go up at the end of sentences. "Glad you're here. It's... odd." "They're all odd, Calloway." She ducked under the tape. "Walk me through." Calloway consulted his notebook. "Victim is male, mid-fifties, found seated at his stall. No obvious trauma. The market's usual clientele gave statements—or as much as they ever give. Mostly they're denying they saw anything." "Usual clientele?" Quinn glanced at the dark stalls. She could feel eyes on her. "This is the black market I've been hearing about? The one that moves around?" "That's the word. Underneath Camden this month, apparently." Calloway lowered his voice. "Some of these people are... I don't know. The uniforms are spooked. One of them swears a shadow didn't move the way it should have." Quinn didn't react. She stepped toward the stall. A constable with a camera was finishing up; the flash popped, throwing the scene into harsh relief. The victim sat behind a low counter, his back against the tiled wall, his head tilted forward. A man with gray hair and a heavy coat, his hands resting on the counter. On his chest, someone had placed a flat disc of carved bone on a broken leather cord. On the counter beside his right hand lay a small brass compass, its casing gone green with verdigris, its face etched with fine lines that looked almost like writing. Quinn crouched to get level with the body. She didn't touch anything. She studied the man's fingers first—no defensive wounds, no skin under the nails, no bruising on the knuckles. His shoes were polished but laced unevenly, one loop larger than the other. His coat was buttoned wrong, the second button in the first hole, fabric pulling at the hem. "When was he called in?" "Just after two. A vendor two stalls down said he'd been sitting like that for an hour before anyone tried to wake him. Thought he was asleep." "An hour." Quinn looked at the counter. No disturbed dust. No drink, no food wrappers. The stall's other wares—jars of dried roots, bundles of herbs, small hammered-copper charms—were arranged in neat rows. Too neat. A black-market stall with neat rows. "Who's the civilian?" She'd noticed her a moment after the body: a young woman in round glasses and a worn leather satchel, standing a few feet back from the cordon, hugging a notebook to her chest. Curly red hair pulled back, freckled complexion, green eyes behind lenses that caught the oil lamps. Eva Kowalski. Quinn knew the name—she'd seen it in the files on the clique she'd been building, the group of young people with too much money and too many convenient alibis. Kowalski worked at the British Museum. She was the best friend of Aurora, the one Quinn hadn't yet been able to pin down. "She's the museum liaison," Calloway said. "Some of this stuff looked like artifacts, so the DI called her in to catalogue. She's been waiting." "Of course she has." Quinn straightened. "What's your read, Calloway?" Calloway flipped a page. "Honestly? I think it's an overdose. These markets sell all sorts of black-market pharmaceuticals. Or maybe a bad batch of something. He's got no trauma, no sign of a struggle. Could be a heart attack, even. The stall's been stripped—someone probably nicked his cash and his good product after he died. That's why it's so tidy." Quinn let the silence stretch. She looked at the compass on the counter. Its needle was pointing not at the stairwell or the service tunnel but at the boarded-up track tunnel at the far end of the platform. She filed that away. "The stall hasn't been stripped," she said. "Ma'am?" "It's been arranged." She pointed at the rows of jars without touching them. "Look at the spacing. Every jar is exactly the same distance apart. No one fleeing after robbing a dead man lines up his merchandise. And the victim's coat is buttoned wrong. His shoes are laced unevenly. Someone dressed him." Calloway blinked. "Dressed him? Why would—" "Because he wasn't killed here." Quinn moved around the side of the counter, careful not to step where the dust had been disturbed. The floor was filthy—soot, old grime, the fine gray powder of decayed concrete. She crouched again. "Look at the floor. Drag marks, but they stop at the stall's entrance. The dust inside the stall is undisturbed. If he'd been killed here, there'd be some disruption from the body falling, or from whoever found him." "Maybe he died sitting up." "Dying people don't button their coats wrong and then fold their hands on the counter." Quinn looked back at the body. "And rigor. He's stiff, but the position is too upright. Rigor would have set in where he fell, not where someone posed him." Calloway was quiet. Eva Kowalski shifted her weight, and Quinn caught the movement in her peripheral vision. The young woman was watching her, not the body. "What about the compass?" Eva's voice was soft, a little hesitant. She tucked a strand of hair behind her left ear. Quinn turned. "What about it?" "It's not... I mean, it shouldn't be pointing there." Eva gestured toward the boarded-up tunnel. "There's a wall there. Compasses point north, or at least toward whatever you set them to. That one's pointing at a dead end." "Cheap trinket," Calloway said. "Probably magnetic interference from the tube lines." "There's no power down here," Eva said. She looked at Quinn, not Calloway. "The rails were pulled up decades ago. There's nothing to generate a field strong enough to turn a needle like that." Quinn studied her for a long moment. "You're the occult researcher. What do you think it is?" Eva hesitated. She glanced at the carved bone disc on the victim's chest. "The mark on the bone is a gate sigil. It's not from any historical period I've seen. It's not a museum piece. It's... contemporary." "Meaning?" "Meaning someone made it recently, and they made it for a purpose." Eva's fingers went to her hair again, then dropped. "I think someone killed this man somewhere else and brought him here. And I don't think they carried him through the door." Calloway gave a nervous laugh. "What, through the wall?" Eva didn't answer. She was looking at the compass again, at the needle trembling slightly, still pointing at the boarded-up tunnel. Quinn walked to the stall's back wall. The tiles were dark with age and grime, but as she held her phone light up, she saw what she'd missed from a distance: a seam in the tile work, too straight, too clean, running in a rectangle roughly the height and width of a door. There was no handle. No hinges. Just a seam where a door should have been. "Calloway," she said quietly. "Get me the station plans for this place. I want to know what's behind this wall." "I can tell you what's behind it," Eva said. "Nothing. It's solid earth. The tunnel collapses about twenty meters that way. There's no room for a door." Quinn pressed her palm flat against the tile. It was cold—colder than the surrounding wall, cold enough to sting. The compass on the counter, she noticed from the corner of her eye, had begun to spin, slow and deliberate, as if it had just woken up. She looked at the seated dead man, at the bone disc on his chest, at the too-tidy stall and the untouched dust. "Someone went to a lot of trouble to make this look like an ordinary death," she said. "That tells me it wasn't one. And this door—this seam—is what they don't want us to find." Calloway was already on his phone, thumbing for the station plans. Eva Kowalski was watching Quinn with an expression Quinn couldn't quite read—not fear, exactly. Recognition, maybe. Quinn made herself look away first. There was something in that wall, something that made the hair on her arms stand up, something that made her think of her partner Morris and the three-year-old file she'd never been able to close. "Nobody touches the compass," she said. "And nobody touches the body until I've seen what's on the other side of this tile." The needle had stopped spinning. It was pointing at her now. She told herself it was coincidental. She had never been good at believing her own reassurances.
