The escalator had stopped years ago, frozen halfway down like it had choked on the dark. Detective Harlow Quinn took the service stairs instead, boots finding the edge of each tread. Water dripped somewhere below, slow as a metronome. The air thickened with cold iron and old electricity. Her torch cut a white strip through the stairwell. Camden roared up on the street. Down here, London held its breath. A uniform waited at the bottom, helmet tucked under his arm. He looked too neat for a place like this, like someone had dropped him from a different life. “Evening, ma’am. You’re the one with the token.” Quinn pulled a knucklebone from her pocket. It sat in her palm like a tooth, polished by handling. A line of tiny scratches ran around it, notches that formed a circle if you stared long enough. The uniform’s eyes stayed on it. “Where’d you get that?” Quinn kept walking. “Evidence.” He swallowed his questions and led her through an arched corridor that once funnelled commuters toward platforms. The tiled walls had peeled into islands of grime. Posters clung in tatters: smiling faces advertising shows that had closed before some of the officers upstairs had been born. The corridor opened into a cavern that shouldn’t have fit under Camden. Lanterns hung from cables, throwing honey-coloured light over a maze of stalls built from scavenged doors and sheet metal. The market buzzed like a nest disturbed with a stick: low voices, clinks of glass, the rustle of paper, the occasional metallic knock that sounded like a coin dropped on stone. Quinn’s watch strap creaked as she checked the time. 02:17. Her wrist felt colder down here. People watched her. Not the curious kind of watching. The counting kind. A cordon of blue-and-white tape cut across the near end of the platform. Two forensics techs in white coveralls stood beside a stall that sold jars of something cloudy. One jar held what looked like a moth the size of Quinn’s hand, wings pinned open in a pale suspension. Her colleague waited by the tape. Detective Constable Imani Patel had her hair tied back and her sleeves rolled to the elbow as if she’d come prepared to scrub blood off the world. She held a small notepad, pen poised. Patel’s gaze flicked over Quinn’s face, then past her shoulder toward the market crowd. “Thought you’d bring half the Yard with you.” Quinn ducked under the tape. “I left them where they belonged. On the street, pretending this place didn’t exist.” Patel moved with her, careful not to touch anything. Her shoes stuck for a moment on the tacky platform. “Tell me you saw the entrance yourself.” Quinn’s eyes tracked the platform edge, the old safety line half buried under soot. “I saw enough. Someone met our witness down here last night. He didn’t walk back out.” Patel tapped her notepad once. “Witness. You mean the bloke who rang in that tip about stolen artefacts?” Quinn stopped at the edge of the light. The market noise dulled in the cordoned area, as if sound respected police tape. Beyond it, a body lay on the platform tiles. The victim’s head tilted toward the tracks, mouth open on nothing. His jacket had been unzipped and peeled back, shirt dragged up. The skin of his chest shone waxy under the torchlight. A thin cut ran from his collarbone to his sternum, neat as a tailor’s line. No pooling blood. Patel crouched near the feet, not too close. She stared at the cut, then at the victim’s hands. “Knife. Clean work. Street gang sort of clean. Quick slice, take what you want, make a point.” Quinn knelt on the opposite side and looked at the man’s fingernails. Dirt and black powder packed under them. The pads of his fingers showed faint burns, like he’d handled something that held heat longer than it should. “What’d they take?” Quinn asked. Patel opened her free hand. A clear plastic evidence bag dangled from her fingers. Inside sat a small brass compass, old enough to have lived in someone’s pocket through wars. Its casing carried a patina of green. Protective sigils had been etched around the face, lines too precise for idle decoration. “The weird trinket he brought. Forensics found it in his coat lining. Thought it was a prop at first.” Quinn stared at it. Something in her stomach tightened, a knot pulled by an unseen hand. “Where’s the needle pointing?” Patel frowned. “What?” “The needle. It’s a compass.” Patel lifted the bag and turned it. The needle quivered, then settled. Not north. It pointed toward the tracks. Patel’s lips pressed into a line. “Magnets. Someone played games.” Quinn reached out. The tech nearest them shifted, ready to object, but Quinn held up her warrant card with two fingers and kept her eyes on the compass. “I’m not touching it. Hold it steady.” Patel held the bag still. The needle jittered, skittering as if it wanted to bite through plastic, then steadied again toward the darkness beyond the platform edge. Quinn’s torch followed the direction. The tracks lay half submerged in stale water. A rusted maintenance ladder disappeared down the tunnel wall. In the tunnel, the dark didn’t sit flat. It folded. Patel leaned closer, squinting. “That tunnel’s just a tunnel.” Quinn angled the light. The beam met something like heat shimmer, except no heat lived down here. The air rippled in a vertical seam, a faint distortion that made the tunnel bricks look like they’d been painted on wet paper. Patel’s breath caught, then she turned it into a scoff and stood. “Optical illusion. We’re underground. Damp. Light bends.” Quinn rose. Her knees cracked and the sound snapped sharp in the hush. “Damp doesn’t make a compass lie.” Patel pointed at the body. “Look at the cut. No hesitation marks. No tearing. Whoever did it knew blades.” Quinn walked around the body, slow, letting her eyes catalogue. The victim’s shoes—cheap trainers—had grey grit on the soles. Not the red dust that coated parts of the platform here, ground down brick and rust. Grey grit belonged to the stairwell and the service corridor. “So he came in through the stairs.” Quinn looked at the tiles around the body. “Where’s his footprint trail?” Patel glanced down, then back up with impatience written across her forehead. “Forensics—” Quinn moved closer to the cut. The skin around it looked too calm. No bruising, no swelling. The edges stayed pale, as if the knife had never touched flesh. Patel watched her face. “You see something.” Quinn lifted the victim’s left hand with two gloved fingers. The hand flopped with dead weight. She turned it palm-up. A faint circular mark sat in the centre, like someone had pressed a coin heated over a flame into his skin. The mark held tiny lines, not random, a pattern too deliberate for injury. Patel leaned in despite herself. “Branding?” Quinn traced the air above it. “Stamp. Not metal. Something else.” Patel straightened, shoulders tightening. “Quinn, we’re not doing ghost stories. We’ve got a dead man, a knife wound, a stolen artefact case. The superintendent wants a name by breakfast.” Quinn’s jaw clenched. The old instinct rose in her, the one that had kept her alive through riots and raids. Follow what you can prove. Ignore the noise. But the noise, down here, wore a different skin. A market vendor stood behind a stall of twisted candles, watching them. The vendor’s eyes looked too pale. His hands never stopped moving, stringing something that glinted like fishbones. Quinn stepped away from the body and addressed Patel without taking her eyes off the vendor. “Who found him?” Patel flipped a page. “Market security. If that’s what you call it. A bloke named Gage. He called 999 from a burner phone and vanished before uniforms arrived. Locals put the tape up themselves. They wanted us contained in one corner like we were the smell.” Quinn’s gaze swept the nearby stalls. Some shutters had been dragged down. Others stayed open, business carrying on in whispers. People treated the cordon like weather: unpleasant but not stopping anything. “So they controlled the scene before we arrived.” Patel’s eyes sharpened. “Now you’re talking sense.” Quinn pointed her torch at the tiles near the victim’s head. A smear of black clung to the grout line. Not soot. It shimmered in the beam, like powdered glass. “Bag that.” One of the techs nodded and moved in. Patel followed the light, then she leaned close and grimaced. “That’s ash. He smoked something. Plenty of these punters smoke weird stuff.” Quinn moved the torch again. The ash formed a curve. Not a spill. A line. She walked the curve, slow. It made a rough circle around the body, broken in two places where boots had smeared it. The circle wasn’t wide, not much bigger than the victim’s outstretched arms. Quinn held her breath and looked at the points where the circle broke. The breaks didn’t match police boots. The tread pattern looked like old leather soles with a raised ridge, narrow, pointed. Not modern footwear. Not a uniform. Patel watched her look. “What?” “Someone stepped into the circle after it went down.” Quinn pointed at the faint ridge marks. “And someone stepped out.” Patel folded her arms. “Fine. A suspect walked around the body. Still a stabbing.” Quinn stepped to the victim’s jacket. Forensics had unzipped it and opened the lining. Quinn didn’t touch. She leaned in close enough to smell it. A sharp tang hit her, like pennies and rain on hot pavement. Under it sat something sweet, rotten at the edges. Patel took a step back, nostrils flaring. “Jesus. What’s that stink?” Quinn kept her gaze on the lining. Thin threads stitched into the fabric, almost invisible until the torch angle caught them. The threads caught light like spider silk. They formed small symbols, repeated, the same shapes etched on the compass face. Patel’s voice flattened. “That’s… sewing.” Quinn’s eyes stayed on the symbols. “That’s a ward.” Patel’s laugh came out hard, a sound with no humour. “You learned that at Detective School, did you?” Quinn’s throat tightened. A memory cracked open: DS Morris’s laugh, the way it had bounced off a brick wall in an alley behind a nightclub, then cut off when the air had torn like fabric. Quinn had stood over his blood and watched it crawl uphill into a drain that wasn’t there. She forced the memory down. She didn’t blink. “Do me a favour,” Quinn said. “Ask your forensics tech what kind of blade makes a cut with no bruising and no blood.” Patel looked at the nearest tech, then back at Quinn with a flicker of irritation. “Oi. Collins. Cut like that—what do you think?” Collins adjusted his mask, eyes darting between the body and Quinn’s face. He held a small camera and tried to look like he belonged. “Honestly? It looks… staged. Like it was made after death. Or with something sharp that cauterised. But there’s no burn.” Patel’s mouth tightened. She shifted her weight. “Post-mortem cut, then. Someone played dress-up.” Quinn crouched again, this time at the edge of the circle. She aimed her torch at the victim’s mouth. His tongue sat dry. No froth. No sign of choking. She glanced at the eyes. Pupils wide, frozen. Fear left marks even in death. This face held surprise, not terror. She looked down at his wrists. Fine red indentations circled both, as if cord had bound him. Not tight enough to cut, tight enough to guide. Quinn stood and stepped to the platform edge, the compass needle still pointing. She peered into the tunnel shimmer. Patel grabbed her sleeve. “Don’t.” Quinn didn’t look away. “You want a name by breakfast. I want a route.” Patel let go, fingers leaving a pale print on Quinn’s jacket. “We don’t go in tunnels without proper kit. We don’t go in—” Patel’s eyes flicked to the shimmer and she swallowed. “We don’t go in whatever that is.” Quinn nodded once, sharp. “Then we make it come to us.” Patel’s brow furrowed. “What does that even mean?” Quinn moved back to the body and pointed at the compass in the evidence bag. “This didn’t sit in his coat by chance. He hid it. Someone marked him.” She tapped the air above the brand on his palm. “Someone drew a circle. Then they used the compass like a key.” Patel shook her head, but her eyes stayed stuck on the compass needle, on its stubborn angle toward the tracks. “You’re building a story because you want it to fit.” Quinn looked past Patel at the market crowd. Two figures in long coats drifted closer, not close enough for the tape, close enough to listen. A stallholder with silver rings stopped ringing up a customer and leaned toward the commotion. Quinn lowered her voice. “This place ran on rules. Entry requirements. Tokens. Private security. People kept order because it benefited them.” She gestured at the open stalls. “A stabbing broke business. A body scared customers.” Patel’s chin lifted, defiant. “So someone dumped him here to scare them.” Quinn shook her head. “No. They cut him neat and left no blood. They kept it tidy. They didn’t want fear. They wanted a message for someone who understood the symbols.” Patel’s eyes narrowed. “And you understood.” Quinn held Patel’s gaze. “I recognised enough to know it didn’t belong in any gang file.” Patel looked away first, lips pressed flat. She scribbled something, pen scratching hard. “What do you want from me, Quinn? You want me to write ‘magic circle’ in the report? You want me laughed out of the unit?” Quinn walked to the tape and lifted it, letting Patel step under and follow her a few paces away from the body. The market noise rose again, voices like water over rocks. A man in a ragged suit leaned out of a stall stacked with old passports and yellowed maps. His eyes tracked Quinn’s watch, not her face. Quinn stopped near a pillar where old Tube signage hung crooked. The word WAY OUT pointed at a brick wall. She turned back to Patel. “You kept your head. Good. Keep it a bit longer.” Quinn nodded toward the compass bag. “That compass didn’t point north. It pointed at a distortion in the tunnel air. That distortion sat inside the arc of the circle. The ward stitched into his coat matched the compass sigils.” Patel’s throat moved. She tucked her notepad away with a stiff motion. “So what did we miss?” Quinn scanned the platform tiles again. The circle. The footprints. The lack of blood. The bindings. The brand. The needle. “The crime scene,” Quinn muttered, then she raised her voice. “It didn’t happen here.” Patel’s eyes snapped to her. “What?” Quinn pointed at the victim’s shoes. “No red dust. He didn’t stand in that circle long enough to pick it up. Someone placed him inside it. They cut him after he died, or they cut him with something that didn’t bleed.” Quinn shifted her torch to the platform edge. “They used that compass to open whatever sat in that tunnel, then they brought him through and laid him down like a parcel.” Patel’s face tightened, then her gaze drifted to the shimmer again. Her confidence cracked at the corner, just enough to show something raw underneath. “You’re telling me someone dragged a corpse through a wall.” Quinn watched the market crowd. The pale-eyed vendor’s hands paused for the first time, his fishbone string going still. Quinn lowered her torch and spoke without raising her voice. “I’m telling you our killer didn’t need the stairs.”
