The Northern line dragged its roar across the ceiling and dropped grit from the vaults. Harlow Quinn ducked under the tape at the mouth of the disused Camden platform and tasted iron and ozone on the back of her tongue. Her torch cut a cone through the dark. Tile walls sweated. A row of dead ticket gates stood with their jaws open. Beyond them a man lay on his back across the concrete, arms flung wide, coat spread like a bat wing. DC Ellis waited beside the body with his notebook shut and his gloves still in his pocket. “You beat traffic.” “I walked the last half mile. Camden Road shut for works.” “Lucky you. Drunk took a header off the maintenance walkway, looks like. Cracked his skull on the gate. Council lads found him on the early check.” Quinn stepped past him and crouched. Her knees popped. The worn leather on her left wrist caught the torchlight as she steadied herself against the gate. Sharp jaw set. Brown eyes narrowed against the dark. Crop of salt-and-pepper hair damp with tunnel sweat. Eighteen years left a posture no office chair undid, spine straight even in a crouch. Blood mapped the man’s shirt in a black fan from sternum to chin. A slit opened his coat from left rib to right hip. Clean edge. No ragged tear. “Where is the blood on the floor?” “He bled out under the coat. Soaks in.” Quinn swept the beam left, then right. Concrete showed pale under a skin of dust. Footprints tracked in from the stairwell, two sets of boots, hers and Ellis’s, and the scuff of the council crew. No pool. No drag. No spatter arc on the gates. A wound that wide painted the ground. It always painted the ground. She rose and circled the gates. Her shadow climbed the tile and fell off. “How long since a train ran through here?” “Sixty years. Sealed in the sixties. Kids break in for tags.” “Show me tags.” The walls held no paint. No cans. No fag ends. No piss stink. The air smelled of burnt sugar and hot copper. Stalls left ghosts in the dust, long rectangles where something heavy had stood and then lifted, awning poles scoring half-moon grooves by the wall. Chalk marks looped across the tiles at ankle height, circles inside circles, broken where a shoe scuffed through. Ellis flipped his notebook open and shut. “Gang thing, then. Shanked upstairs and dumped down the vent. Kids move bodies for a laugh.” “With clean shoes?” Quinn tipped her torch to the dead man’s feet. Trainers white at the toe, laces knotted double, soles free of tunnel grime. Trouser cuffs dry. Fingernails packed with something green-black under the tips, like crushed herbs. His right fist clenched a disc of yellowed bone, thumb-sized, a hole bored through the centre. His left hand gripped a small brass compass. Verdigris ate the casing in green scabs. The face bore fine cuts, rings and bars and crossed lines, sigils etched around the rim. The needle shivered and held north-northwest, straight at the blank tile wall behind the gates. Quinn held her own compass from her pocket beside it, a standard Silva. Her needle swung to magnetic north, east of the dead man’s needle by a full hand span. “Iron down here pulls needles. Interference.” “This much?” A stairwell door banged. Footsteps rattled down. A short woman in a waxed jacket picked through the dark with a torch in one hand and the strap of a worn leather satchel full of books cutting into her shoulder. Curly red hair escaped a clip. Round glasses flashed. Freckles stood dark against pale skin in the torch glare. Green eyes fixed on the body and widened. “Back behind the line, love.” “I rang her.” Ellis lifted a hand. “British Museum. Restricted archives. She IDs odd bits for us.” “Eva Kowalski. Ancient History. I catalogue—” “You catalogue what no one else wants to touch.” Quinn straightened to her full height and looked down the extra half foot at the newcomer. Eva tucked hair behind her left ear and hitched the satchel higher. “Who moved him?” “No one moved him.” “Someone did.” Eva stopped at the edge of the dust and stared at the rectangles, the chalk, the bone disc, the compass. Her breath shortened. “You see it.” “I see a dead man with no scene.” Quinn pointed the beam at the scuff through the chalk ring. “What breaks a circle like that?” “A foot. A fight. A rush.” Eva stepped sideways, careful to place her boots on the concrete ribs between dust sheets, and peered at the bone disc without touching it. “That opens a door. You hand it over and you walk in.” “What door?” “The Market uses it. It sets up down here. It sold things under the street, charms and powders and names. Things the law bans and men crave. It holds one night and shifts with the full moon.” Ellis snorted. “Black market in a sealed Tube. Right. Stallholders with lanterns.” “Stallholders with no need for lanterns.” Eva nodded at the grooves by the wall. “Pole feet. Canvas weight. That rectangle held a table six feet long. That one held cages. See the scatter? Seed husk. Feather down.” Quinn swung her torch low. Pale flecks glinted in the dust where Eva pointed. “Full moon was last night.” “It was.” “So the Market stood here last night and gone by dawn.” Eva tucked hair behind her left ear again and crouched over the compass. “May I?” “Gloves.” Eva snapped on latex from her pocket and lifted the brass case by its edge. The needle held its line, steady as a finger, toward the blank wall. “It finds rifts. Tears. Doors too thin. A Shade artisan built the casing to hold the charge. The sigils keep it from burning out the bearer.” “A man bleeds out and clutches a toy.” “He clutched a tool. He felt the tear open and he reached for the one thing that showed the way out.” Quinn took the compass and weighed it in her palm. Cold bit through her glove. The needle ticked a degree west and settled again. “You handle a lot of dead men’s toys for an archivist.” “I handle books men died writing.” Quinn turned the dead man’s cuff back. A stamp marked the inner wrist in violet ink, a crescent cut by a key. Fresh. Last night fresh. “Entry mark?” Eva leaned in, glasses low on her nose. “Buyer. Seller marks sit on the right hand.” Quinn checked the right hand. The bone disc filled the palm. Under the thumb a burn blistered the skin in a straight line, as if a hot wire had kissed it. “He paid. He argued. The circle broke.” Ellis spread his hands. “Or he bought bad gear and dropped dead in an alley and his mates dumped him where no camera sees. Alchemical substances, you said. Fentanyl with glitter.” “Fentanyl leaves foam. Needle tracks. A smell. This man smells of rosemary and smoke.” Quinn pressed two fingers to the wound edge and lifted. The flesh parted without seep or clot. The shirt fibres stood fused along the cut, melted, not sliced. The skin underneath pearled white. “No blade did this. Heat did this. Heat with an edge.” She remembered another platform three years back, another white face, DS Morris with his coat fused to his chest and no blood on the brick and a report that read misadventure because no other word fit. Her watch ticked loud in the quiet. Ellis saw her face and softened his stance. “Harlow. We log it as suspicious death, post-mortem, toxicology. No need to build a cathedral.” “We log what the dust says.” Quinn walked the line of stall ghosts to the blank wall where the needle pointed. Tiles ran floor to ceiling, grimed, hairline cracks threading through. She laid her palm flat. Cold sucked at her skin. A seam breathed faint warm air against her cheek, a vertical line no wider than a hair, straight as a rule from knee height to overhead. “Ellis. Light here.” The beam struck the tiles. The seam vanished under direct glare and reappeared at the edge of vision. “Subsidence crack.” “Subsidence cracks run with stress. This runs plumb.” Eva joined her, satchel banging her hip, and ran a fingertip beside the seam without touching. “A rift sat here. It opened and it shut. The compass still tastes it.”
