Quinn ducked under the tape at the service shaft off Camden High Street and took the iron ladder down into the dark. Cold breathed up from below. It carried wet concrete and copper and burnt sugar. Her torch cut a white cone through the shaft. Brick gave way to tile. The tile gave way to a platform that had not seen a train in forty years. Blue light strobed from a constable's torch near the far wall. Stalls lined the platform edge. Tarpaulin roofs. Wooden crates. Glass jars with labels in chalk. Strings of dead fairy lights hung between pillars. Dust lay thick across everything except where boots had churned it to mud around a single shape on the ground. The shape was a man. Mid-thirties. Shaved head. A leather apron over a thermal shirt. His arms spread wide. His mouth hung open. His eyes stared at the tunnel roof. DC Ellis stood over him with a notebook slack in one hand. "Morning, guv. Got yourself a Camden stabbing. Nasty one." Quinn stepped onto the platform. Her boots rang on concrete. She checked the worn leather watch on her left wrist. 04:12. "Who has the log?" Ellis flipped a page. "Transit worker heard shouting around three. Called it in. First response thought drunk. Then they saw the blood. Or the lack of it." Quinn crouched. Her sharp jaw set. Her brown eyes tracked the body from crown to boots. No pool spread under him. A thin black line circled his throat. The skin along the line had parted neat as paper. The concrete beneath showed no more than a few dark flecks. "Knife took the carotid. Should have painted the platform." Ellis tapped his pen against the notebook. "Smack head bled out internal? I saw a puncture once swell a chest like a drum. No mess till the pathologist opened him." Quinn did not look up. "Show me a needle. Show me a bruise." A cough echoed from behind a stall. A young woman sat on an upturned crate with a uniformed constable beside her. Curly red hair escaped from under a wool hat. Round glasses caught the torchlight. A worn leather satchel full of books rested against her ankle. Freckles stood stark against pale skin. She tucked hair behind her left ear with a quick hand. "That is Eva Kowalski. Found him. She works up at the British Museum. Says she knows the victim." Eva stood before Ellis finished. She crossed the churned mud with short steps and stopped at the edge of the torchlight. "You moved the jars on his stall." Ellis frowned. "We secured the scene." "You kicked over salt lines. You scuffed chalk with your big boots." Quinn rose to her full height. Military precision squared her shoulders. "You know this place." Eva pushed the glasses up her nose. "This is the Veil Market. It sells things you will not find on any licence. Enchanted goods. Banned alchemical substances. Information for the right price." Ellis gave a short laugh. "Right. Camden night market for wizards." "It moves every full moon. Abandoned Tube station beneath Camden tonight. Next month a crypt. A car park. It needs a bone token to get in." Quinn held out a gloved palm. "Empty your pockets for me." Eva pulled a flat disc of yellowed bone from her coat. A hole pierced one end. A rune burned into the face. "Every buyer carries one. Every seller checks it at the door." Quinn turned toward the body. "He carries one?" Eva nodded toward the right fist. "He never let go of his." Quinn knelt again and eased the fingers open. A twin disc of bone sat in the palm. Scratches marred the rune. "Ellis. Bag this. Photograph first." Ellis crouched with an evidence bag. "So our victim paid entry to buy fairy dust and someone stuck him for his wallet. Wallet is gone, by the way. No phone. Classic robbery." Quinn scanned the stalls. Jars stood intact. Pouches of dried root. Vials of silver liquid. A tray of teeth. Nothing looked rifled. "Robber leaves product worth thousands and takes a phone with no signal down here?" She stood and walked the perimeter of the disturbed dust. Her torch swept low. Boot prints led from the shaft ladder to the body. Two sets. Heavy. Uniform issue. One smaller set with a broken tread. Trainers. Eva's size. No other prints crossed the thick dust toward the stalls or the tunnel mouths. The dust beyond the circle lay smooth as snow. "Where did the killer walk out?" Ellis scratched his neck. "Back up the shaft before the transit bloke came down. Or along the tunnel. We have men checking the northern bore." Quinn followed the smooth dust with her torch to the tiled wall behind the victim's stall. Green and cream tiles formed a diamond pattern. Soot blackened one diamond at shoulder height. The blackening formed a rough arch no wider than a door. "What scorched that?" Eva stepped closer. Her satchel thumped against her calf. "Rift burn. A doorway wore thin. The Market uses them for stock and for escape when police get close." Ellis snorted. "Burn mark from a dosser fire. Kids climb down here all the time." Quinn ignored him and swept the ground at the base of the wall. A small brass compass lay on its side near a crate leg. Verdigris coated the casing. The face bore fine lines that caught the light. Protective sigils etched around the cardinal points. The needle trembled under glass and held firm on the blackened diamond. "Who logged this?" Ellis shrugged. "Trinket from a stall. Junk." Quinn lifted it with two fingers by the edge. The needle did not waver. It pointed at the wall with mechanical intent. "Eva. What does this do?" Eva tucked hair behind her left ear again. Her green eyes fixed on the compass. "A Veil Compass. A Shade artisan crafts them. The needle points toward the nearest supernatural rift or portal. It finds doors you cannot see." Ellis spread his hands. "Or it points north and the wall happens to sit north. Come on, guv. We have a dead man with his throat cut in a drug den. We need dealers, not dowsing rods." Quinn crossed to the victim and pointed her torch at the black line on his throat. "Look at the edge. No serration. No hesitation. A single pass with something sharper than steel. And look at his left hand." The left hand lay open. White powder clung to the fingertips. A broken circle of the same powder ringed the body. Salt. Ash. Chalk. "He drew a circle. Protective sigils. Same marks as on this compass face. Someone scratched through them." She traced the break in the white ring near the victim's knee. A boot-sized smear cut through it from the inside. The smear pointed toward the blackened tiles. "Eva. If a rift opened in that wall, what comes through?" Eva hugged the satchel strap. "Anything with the token frequency. Anything invited. Anything strong enough to force it." Quinn stood in the centre of the broken circle. Her torch beam travelled from the bone token in the evidence bag to the smooth, printless dust to the needle locked on tile. "No one walked in. No one walked out. The killer never touched the dust." Ellis closed his notebook. "So what? He floated?" Quinn met Eva's gaze over the body. "He stepped through there."
