Rain hammered the shutters along Camden High Street and ran in black rivers down the pavement. Quinn ducked under the tape and took the sealed stairwell down. Her boots struck concrete slick with damp and old oil. The air turned cold three steps below street level and smelled of rust, piss, diesel. "You took your time, guv." Patel stood at the bottom with his torch aimed at a rusted gate. Water beaded on his high-vis and his breath smoked. "I came off the A10." Quinn checked the worn leather on her left wrist. The face read 02:14. She squared her shoulders and scanned the tunnel with military straightness in her spine. Patel jerked his chin toward the dark. "Platform's through there. British Transport Police cracked the gate an hour back." Quinn pushed past him. Her torch cut a white bar through dust. The abandoned Tube station opened beneath Camden in a vault of soot-stained tile and snapped cables. A dead ticket hall yawned to the left. To the right the platform stretched fifty metres into dark. A body lay mid-platform under a portable floodlight. Quinn stopped at the edge of the light and let her eyes work. The dead man sprawled on his back in a good wool coat. Early thirties. Pale skin. Dark blood crusted at his left temple. Both hands curled at his chest. His shoes were new and unscuffed except for grey dust on the soles. "No blood pool." Quinn crouched and her brown eyes narrowed. Her sharp jaw set. "Right?" Patel planted his boots wide and shone his torch on the temple wound. "Stabbed or clobbered. Camden beef. Dealers use the tunnels." Quinn ran the beam along the concrete around the corpse. No spatter. No drag marks. No shell. No blade. The dust lay smooth except for two sets of footprints that came from nowhere and stopped ten feet short of the body. "Where are the casings? Where is the weapon?" Quinn rose to her full height and looked down at the platform edge. The drop to the track bed measured four feet. The bed held black water and nothing else. Patel shrugged and his high-vis rustled. "Junkie took a knock and crawled in here to die. We see it every winter." "Eighteen years on the Met and you call this winter death?" Quinn flicked her torch to the dead man's face. No track marks on the neck. No foam at the mouth. No vomit. Nails clean. Coat too dear for a rough sleeper. A scuff sounded behind the floodlight stand. "Eva." Quinn swung the beam up. The light caught round glasses and a flare of red curls. Eva Kowalski froze with one hand on the strap of her worn leather satchel. Books bulged from the top and banged her hip. Freckles stood dark on damp skin. She tucked a curl behind her left ear and blinked in the glare. "Harlow, you need to let me look." Eva stepped forward and her trainers squeaked on tile. Patel blocked her with an arm. "Whoa. Civilians stay behind tape." "She works out of the British Museum store. Restricted archive." Quinn lowered her torch a fraction. Her cropped salt-and-pepper hair dripped rain onto her collar. "Why is she here at two in the morning?" "Ask her." Quinn tilted her head toward the platform and the empty dark past the floodlight. Eva slipped past Patel and knelt by the dead man. She ignored the temple wound and stared at his right fist. "Open his hand." "Evidence—" Patel started forward. "Open his hand." Quinn met his eyes and held them till he dropped his arm. Quinn pulled on a nitrile glove and prised the fingers back. A small disc of yellowed bone rested in the palm. A hole pierced one end. Deep cuts scored the surface in a pattern no pocket knife made. Eva drew breath through her teeth. "Bone token." "What is a bone token?" Quinn turned the disc under the light. The cuts caught shadow. "Passage money." Eva tugged her satchel open and dug past books with cracked spines and loose notes. "This station hosts the Veil Market. Sellers of charms and draughts and banned powders and secrets. Buyers need a token to cross in. The Market shifts ground each full moon." Patel gave a short laugh. "Full moon was last night." "Yes." Eva pulled out a small brass compass. Verdigris bloomed green across the casing and flaked at the hinge. The face bore thin etched sigils around the rim instead of points. Patel rolled his eyes toward Quinn. "Guv, this is Camden. Bloke choked on his own sick and she brings pirate treasure." Quinn ignored him. She watched Eva thumb the compass open. The needle spun once, twice, then locked hard toward the tiled wall behind the body. The needle shivered and held. "What does that point to?" Quinn stepped closer. Her shadow fell across the dial. "A tear." Eva stood and held the compass flat. Her hand shook and the needle never wavered from the wall. "This compass finds rifts. A Shade made it to sniff out weak doors. It points to the nearest one." Quinn crossed to the wall. Tiles sweated with condensation except for one tall arch of dry brick. The arch matched the height of a door. The mortar smelled scorched. Under the torch the soot formed a clean edge, floor to ceiling, wide as a market stall. She pressed her palm near the brick and heat prickled her skin though the tunnel breathed ice. "Patel, your dealer theory needs feet." Quinn swept her beam from the footprints to the body to the dry arch. "Two sets walk out of solid wall and stop. No prints walk back. No blood where a head wound bleeds out. Shoes clean except for dust no Tube tunnel makes. Smell that." Patel sniffed and wrinkled his nose. "Burnt sugar. Ozone." "And rot under it." Quinn crouched again by the dead man's coat and lifted the lapel with two fingers. The lining bore a stamped mark, a small eye inside a circle, inked in violet that glistened though the wool stayed dry. Inside the breast pocket she found a folded paper packet. White powder clumped at the seam and sparked faint blue when the torch hit it. Eva crouched opposite and her glasses fogged. "Alchemical stock. Market grade. You cannot buy that on the street." "This is a closed station. How did he get in with a token and powder and no gate forced?" Quinn looked from the token to the compass needle to the dry arch. Eva tucked hair behind her left ear again and her green eyes flicked to Quinn. "You saw a door like this before. With Morris." Quinn went still. Her hand tightened on the torch till the metal creaked. Three years back DS Morris bled out in a tunnel off Aldgate with no wound Quinn could find and no suspect on camera. The file still sat on her desk. "You knew Morris?" Patel frowned and his torch dipped. "He worked my case for a week." Eva kept her gaze on Quinn. Quinn stood and walked the ten feet from the arch to the corpse in slow paces. Her boots left sharp prints in dust. The victim's prints overlaid hers in depth but not in direction. The soles pointed toe-first from the wall, as if dropped. She knelt and turned the dead man's head. The temple wound held no grit, no rust, no brick dust. The edges puckered white, bloodless, like a burn sealed shut from inside. "Not stabbed here. Not beaten here." Quinn lifted her eyes to the arch and the compass needle that pinned it. "He died on the other side of that wall and fell through when the Market moved on."
