Quinn ducked under the tape at the Camden siding and took the iron ladder down. The air below tasted of soot and wet lime. Her torch cut a white lane through black dust. The disused platform stretched ahead, tiles blistered, posters stripped to paste scars. A row of shuttered kiosks lined the far wall where no kiosks belonged on any Transit plan. Their shutters wore fresh padlocks. Their shelves behind the grilles held jars and twists of wire and paper packets stamped with hand marks. Her salt-and-pepper crop brushed the low cable tray. Her brown eyes narrowed. Her sharp jaw set. She moved with military precision, boot to boot, torch level. The worn leather watch on her left wrist ticked against the hush. A uniform stood over a shape on the platform edge. “You took your time.” Quinn swept the beam across his boots and the concrete around them. “You trampled my scene.” The uniform shifted his weight and hooked his thumbs in his vest. “Dispatch flagged a body in a service tunnel. I came straight down. No one else touched him. Dr Singh called it before you arrived.” Quinn dropped to a crouch beside the dead man. He lay on his back with his arms folded, palms up, chin tipped to the tunnel roof. Late forties. Shaved head. A trader’s apron knotted at his waist, pockets turned out. His skin held a grey pull, lips cracked, eyes open and filmed with dust. No blood pooled under him. No wound opened his coat. His chest sank inward between the ribs, as if a great weight pressed and then lifted. Quinn pressed two fingers to his throat out of habit and felt nothing but cold. “Name?” “No wallet. No phone. One of the Camden rough sleepers, I reckon. Cold got him. Or bad gear.” Quinn ran the torch from his boots to his scalp. “Dust tells another story.” The platform wore a felt of grey dust, thick as ash, unmarked for yards except for a single set of prints leading from the tunnel mouth to the body. The victim’s own prints. No return prints. No drag marks. No scuff where a body fell. The dust around his shoulders lay smooth, pressed flat in a perfect outline, like a stencil. Quinn stood and paced a slow circle. Her beam caught the kiosks again. Stalls. Not kiosks. Wooden counters bolted to the tile, canvas awnings furled above. A chalk board leaned on one shutter with prices in a cramped hand. Dried herbs hung in bunches. Bottles glowed amber and green. The whole row breathed the order of a market set for trade and then abandoned mid-hour. “This is a market.” The uniform snorted and kicked at a loose ticket stub. “Down here? This station closed in seventy-four. Kids break in for parties.” Quinn stopped at the first stall and lifted a jar with her gloved hand. Inside the glass, moth wings shifted and settled, each wing marked with a letter. “Enchanted goods. Banned alchemy. Information for a price. You ever book a party with stock like this?” Footsteps rang on the platform behind them. A young woman picked her way through the dark with a torch in one fist. Curly red hair escaped a woollen hat and clung to her freckled cheeks. Round glasses caught the light. Green eyes widened at the tape and the body. A worn leather satchel full of books banged her hip. She tucked a strand of hair behind her left ear and stopped short at the sight of Quinn’s warrant card. “You need to stay back.” Quinn raised a hand and blocked the beam with her palm. “Name.” “Eva Kowalski. I work in the restricted archives at the Museum. I use the service passage for my walk home. I found him. I called it in.” The uniform tapped his notebook. “She waited up top till we arrived. I took her details.” Eva hugged the satchel strap and stared at the stalls. “You see them too. Good. Last month they denied the stalls existed.” Quinn fixed her torch on Eva’s face for a beat, then lowered it. “You pass through here often?” “Most nights. The passage cuts ten minutes off my route. Tonight the gate stood open. The stalls were lit. Voices everywhere. Then the lights died.” The uniform cut in and flipped his notebook shut. “With respect, ma’am, witnesses hear voices in tunnels. Sound carries off the Northern line. Bloke had a heart attack among squatters and they legged it. We bag him and go.” Quinn ignored him and crouched again by the open palms. Verdigris stained the right palm in a perfect circle, green as old copper. In the centre of the stain the skin puckered around a small brass disc half-sunk in the flesh. She eased it free with tweezers from her kit. A small brass compass sat in her palm. The case wore a patina of verdigris. The face bore etched sigils, rings within rings, each line cut with tool precision. The needle trembled, swung, and held firm on the blank brick of the tunnel wall behind the stalls. No north mark matched its pull. The needle quivered with live tension, as if hauled by a wire. Quinn held it up to Eva. “You recognise this?” Eva crouched without invitation and peered through her round glasses. She tucked hair behind her left ear again and her breath fogged the brass. “A Shade made that. They sieve ore from rift wash and etch wards into the lid. It seeks the nearest tear. Traders carry one to find the door when the market moves.” The uniform laughed once, short. “Rift. Right. Next you tell me he paid entry with fairy dust.” Quinn turned the dead man’s left fist open. The fingers resisted, then gave. In the hollow of his palm rested a short length of carved bone, polished by handling, one end drilled for a cord. A token. Quinn set the token beside the compass on the concrete and lined them with her torch. “Bone for entry. Brass for direction. The stalls form a market with no punters and no till. One set of prints walks in. None walk out. No blood. No wound except a caved chest and a scorched palm. Your heart attack fails to explain the stock, the token, the compass, or the dust.” She rose to her full height and crossed to the wall where the needle pulled. Five foot nine of her blocked the beam. Brown brick, Victorian courses, weep of salt and water. She pressed her gloved palm flat. The brick drank the heat from her hand faster than brick should. Cold crawled up her wrist and stopped at the worn leather watch. The second hand stuttered, jumped, and held. Eva stepped close with her satchel clutched to her ribs. “The market moves each full moon. It needs a door. The compass finds it.” Quinn ran her torch seam by seam across the mortar. One joint showed no dust. A hairline gap breathed cold air in a steady thread. She pressed her thumb to the gap and felt a pull behind her navel, as if the wall inhaled. She glanced back at the body. The outline in the dust matched the span of a man set down with care, not dropped. Arms folded. Palms up. Token kept. Compass kept. Apron pockets turned out by hands that searched after death and left the valuables of this place untouched. Quinn levelled the beam on the uniform’s boots and then on the empty stretch between body and wall. “You walked in through dust. He left none going back. No one carried him; four feet would mark the felt. He arrived through that wall and died on this side of it. Your squatters never touched him because they never entered here.”
