The old station lay below Camden like a broken tooth under the city. Detective Harlow Quinn stepped off the maintenance stairs and into a platform that no longer existed on any Transport for London map. Tiles the colour of old teeth climbed the walls. Half the station name remained above the tracks. —DEN. Water dripped from the tunnel mouth. It struck the rails with the steady patience of a metronome. Someone had strung red-and-white police tape across the platform. It looked pathetic against the market beyond it. Stalls crowded the darkness beneath shuttered ticket windows: cages of blue moths, stoppered bottles containing weather, knives laid on velvet beside jars of teeth. A woman with a crow’s skull for a face pulled down the grille of her stall when Quinn passed. Another vendor covered a tray of black coins with a cloth. The market had gone quiet for the police. That silence bothered Quinn more than the corpse. DC Arjun Bell crouched beside it near the yellow line, his suit trousers dark at both knees. He wore latex gloves and held a torch under his chin while he stared at something on the floor. “You got here fast,” he called. Quinn checked the cracked face of her leather-watch. “You called at six twenty.” “You answered at six twenty-one.” “I was driving.” Bell rose, broad-shouldered and round-faced, his tie loosened beneath a rain-spotted collar. “You drove here?” “I drove to Camden. Your constable led me through a kebab shop and a locked cellar. Don’t make it sound heroic.” Bell looked past her towards the stairwell. “You bring the token?” Quinn opened her palm. A small disk of polished bone rested there, drilled with a hole at its centre. Black thread looped through it. The surface held a carved eye that seemed to follow movement. Bell scratched at his jaw. “Still hate that thing.” “It got us through the door.” “It got us through a wall. There wasn’t a door.” “Write that in your report.” “I enjoy employment.” Quinn pocketed the token and looked down at the dead man. He lay on his back with one arm thrown across the platform edge, fingers dangling over the tracks. He wore a burgundy velvet coat, cream shirt, and polished boots with silver buckles. Blood had soaked the left side of his chest and spread beneath him in a dark, glossy fan. The wound looked clean. Too clean. A brass compass sat near his right hand. Verdigris stained the seam around its casing. Protective sigils ringed its face in cramped, sharp lines. The needle spun in fast, frantic circles. Quinn did not touch it. “Name?” “Leon Vetch.” Bell consulted his notebook. “Human. Thirty-eight. Trader, fence, occasional information broker. Market regulars called him a rat, which I gather wasn’t affectionate.” “Who found him?” “Stallholder named Mrs Wren. Sells remedies.” “Real remedies?” Bell’s mouth tightened. “I didn’t ask.” “You should have.” “She gave him a bottle marked WOLF LUNG.” “Then you definitely should have.” Bell pointed to the corpse. “Single stab wound. No weapon. Blood loss. The pathologist won’t get down here until the market agrees not to eat him.” “Who told you that?” “A man in a fur hat with no eyelids.” Quinn bent beside the body. The smell hit her: iron, damp brick, old electricity, and a chemical sweetness beneath it. She lowered two fingers near the dead man’s throat. The skin had cooled, but not enough for the station’s temperature. No pulse. No breath. A thin streak of blood ran from Vetch’s left ear to his collar. Quinn studied his hands. His fingernails bore soot, except for the thumb and forefinger of his right hand. Those two digits remained clean. Bell watched her. “Fight with the killer?” “No bruising on the knuckles. No skin under the nails.” “He could have cleaned up.” “Not after losing that much blood.” She followed the smear beneath Vetch’s arm. It travelled three feet across the platform, then stopped. No drag marks. No footprints through it. Nothing except a small, crisp crescent in the blood, as if someone had pressed the edge of a coin there. Bell shuffled closer. “I saw that. Think it’s a stamp.” “From what?” “One of the market freaks.” Quinn lifted her eyes. At the far end of the platform, Eva Kowalski stood behind the tape with her worn leather satchel clutched against her ribs. Her curly red hair had escaped its knot and formed a bright cloud around her face. Her round glasses caught the blue flash of a forensic lamp. A uniformed constable stood beside her, pale and unhappy. “Evie,” Quinn called. “Why are you in my scene?” Eva tucked hair behind her left ear. “Your officer rang the British Museum. He asked for someone who could read symbols.” Bell folded his notebook shut. “I asked for an expert. They sent her.” “They sent the only person foolish enough to take a call before breakfast,” Eva muttered. Quinn lifted the tape. “Come through. Don’t touch anything. Don’t step in the blood.” Eva ducked beneath it and stopped near the compass. Her green eyes sharpened behind the lenses. “Oh.” “That means something,” Bell noted. “It means I’d like not to be standing beside it.” “You know what it is?” “A Veil Compass.” Eva pointed without lowering her satchel. “Shade-made. It detects rifts. Doors between places that shouldn’t connect.” Bell looked at the flooded tunnel. “There’s a tunnel.” “No.” Eva’s freckled face had gone tight. “A rift doesn’t mean an entrance. It means a tear. It can open in a mirror, inside a cupboard, under somebody’s tongue.” The constable made a wet choking noise from behind them. Quinn looked at the spinning needle. “Why did Vetch have it?” “People use them to find crossings. Smugglers. Grave robbers. Cults. Anyone who wants to get from one locked room to another without dealing with locks.” Bell tapped his pen against his notebook. “So he found a doorway down here, somebody stabbed him over it, end of story.” Quinn kept her gaze on the body. “If he found a doorway, why is the compass still here?” “Could have dropped it.” “He kept his hand around it while he died.” Bell glanced down. “His hand’s open.” “Now it is.” Quinn drew a pair of evidence forceps from her kit. She caught the compass by its outer ring and lifted it. The needle bucked harder, then snapped north-east. Not towards the tunnel. Towards the dead man’s chest. Eva’s breath caught. “Put it down.” Quinn held the compass above Vetch’s wound. The needle struck against the glass face, fixed there with such force that the casing vibrated between the forceps. Bell stared. “That’s not possible.” “Your report is getting interesting.” Quinn passed the compass to Eva. “Hold it above his left shoulder.” Eva swallowed and did it. The needle spun loose. “Over his boots.” It pointed to the tunnel. “Over his chest.” The needle locked again. Bell crouched. “You think there’s something inside him?” “I think somebody wanted us to find this body where we found it.” “You don’t leave a body in a public market if you want to hide it.” “No.” Quinn ran her torch along the blood fan. “You leave it here if you want witnesses. You leave a weaponless stabbing, a compass, and a corpse beside a tunnel because you want everyone to look at the tunnel.” Eva stared at Vetch’s velvet coat. “The blood is wrong.” Bell threw up one hand. “Thank Christ. Somebody else sees it.” “Don’t celebrate.” Eva knelt carefully, keeping clear of the stains. “It’s too dark at the edges. Human blood oxidises, but this…” She leaned closer. “It smells burnt.” Quinn had smelled it too. That sweet chemical note. “Where’s the blood spatter?” she asked. Bell scanned the tiles. “There.” Three droplets marked the wall at knee height. A fourth sat on the underside of a bench. All lay to Vetch’s right. “The wound is on his left,” Quinn said. “He turned when he got stabbed.” “Then the spray would curve. These drops travelled straight.” Bell looked from the stains to the corpse. His earlier certainty drained from his face. Quinn set her torch against the tiles and examined the platform edge. The yellow line had peeled in long strips. Beneath it, someone had scratched fresh marks into the concrete: four parallel cuts, each no longer than a finger. They began at the yellow line. They ended at Vetch’s heel. “Eva.” Eva shifted closer. “Know those?” Her glasses slipped down her nose. She pushed them back with one knuckle, then went still. “They’re warding marks,” she whispered. “Or part of them.” “Part?” “They’re upside down.” Bell gave a short laugh that held no humour. “Upside down wards. Great. That clears it up.” Eva looked at him. “A ward pushes something away. Turn it wrong, it does the opposite.” Quinn followed the line of cuts. There were four at the platform edge. Four more hidden beneath Vetch’s coat hem. Another set beneath the bench, where the blood droplets sat in a neat row. Not random. Not a struggle. A shape. She stepped backwards until her calves touched the ticket barrier. From there, the marks connected across the platform in a wide circle, broken only by the corpse at its centre. A circle with its mouth open towards the tracks. Quinn looked at the tunnel. Water kept falling somewhere inside it. The sound had changed. It no longer struck rail or stone. It landed softly, like drops falling into deep water. “Bell,” she called. He turned from the body. “Get everyone off this platform. No panic. No shouting.” His eyes narrowed. “Why?” Quinn pointed at the clean fingers on Vetch’s right hand. “He didn’t die holding the compass. He used it to find the rift.” She pointed at the bloodless crescent near his body. “Then someone opened it inside him.”
