Rain hammered Camden High Street at midnight and turned the shopfront glass black. Detective Harlow Quinn stood under the awning of a shuttered newsagent, rain dripping from her closely cropped salt-and-pepper hair, the worn leather strap of her watch dark with water against her left wrist. Across the road, Tomás Herrera stepped out of an all-night pharmacy with a canvas medical bag pressed against his ribs. Quinn watched his short curly hair catch the light from a bus stop advert. He turned toward the canal, and the Saint Christopher medallion at his throat flashed once. His left sleeve clung to the scar that ran the length of his forearm, a pale line visible each time his arm swung into the glow of the streetlamps. She had tracked him from The Raven's Nest in Soho, where green neon bled across wet pavement and a bookshelf in the rear wall had opened onto a room with no windows, no cameras, and a table scarred by knife cuts. Tomás had stepped out of that room with the same bag. He had seen her warrant card through the bar glass and had kept walking. Quinn crossed the kerb and stepped into the rain. "Tomás Herrera." He stopped with one foot in the gutter. Water rushed around his shoe and carried cigarette ends, a crushed coffee cup, and ticket stubs toward the drain. "Detective Quinn. You have wet socks." "I have questions about the man you stitched up at the Nest tonight." "Then book an appointment." "You lost your licence, Tomás. You do not get appointments. You get cells and paperwork." His warm brown eyes dropped to the bag. His thumb rubbed the canvas seam in a short, repeated stroke. "You followed me from Soho for this? A bag of bandages?" "Open it." "Rain ruins bandages." "Rain ruins a lot of things. Open it." A night bus hissed past and threw a sheet of water across the pavement. Tomás used the spray as cover. He spun on his heel, vaulted a stack of delivery crates outside a noodle bar, and sprinted toward the canal bridge. Quinn drove her shoulder into the crates and felt them topple behind her. Bottles rolled across the pavement. A shopkeeper thrust his head out of a doorway and shouted at the mess, but Quinn kept her eyes on the medical bag as it bounced against Tomás's back. She lifted the radio clipped at her collar. "Control, Quinn. Herrera on foot, Camden High Street, moving toward Chalk Farm Road. Request units at the canal bridge and the Tube station." Static chewed the response into fragments. She heard her call sign, a street name, and a time estimate that promised help too late to matter. Tomás cut through a row of market stalls with canvas roofs sagging under pooled rain. Traders had left crates, garment rails, and buckets of cut flowers under padlocked tarps. Quinn followed him into the narrow lane between two stalls. Her shoe caught the leg of a folding table. Metal screeched across concrete, and a bucket tipped, spilling black water and drowned lilies at her feet. "Stop where you are, Tomás." "You keep shouting that like it has worked before." He ducked under a rail of wet leather jackets and vanished behind a shutter painted with a giant eye. Quinn pushed the jackets aside. Cold water ran down her neck. The jackets slapped her face and shoulders, and the smell of wet hide filled her nose. She came out the other side in time to see Tomás leap over a bicycle that a courier had dropped across the pavement. The courier grabbed at the handlebars and swung a fist at the air where Tomás had been a second before. "Oi. Watch the bike." Quinn hurdled the front wheel. Her landing jarred her knees and sent pain up into her hips. "He has a head start because he eats better than you, Detective." "I eat fine." "You eat petrol station sandwiches in a parked car. I treated one of your lot for scurvy last winter." "Name?" "Patient confidentiality." "You struck gold with that line after the licence went, did you not?" Tomás glanced back. Rain ran off his olive skin and darkened the collar of his shirt. "Ask the people who call me when ambulances refuse the address." He reached the canal bridge and took the steps down two at a time. Quinn followed. The steps shone with algae and discarded gum. A narrowboat sat moored below, its cabin windows lit orange, its roof stacked with plant pots and a rusted bicycle frame. Music drifted from inside, muffled by rain and fibreglass. Tomás ran along the towpath, past a man asleep inside a tent pitched under the bridge, past graffiti that covered the brick in layers of silver and red. His shoes slapped puddles apart. Quinn matched his pace and felt her lungs burn with each breath of cold air. Three years earlier, DS Morris had chased a suspect down a service stairwell near King's Cross and had called for backup from a landing where the radio signal thinned to a thread. Quinn had heard his voice break into pieces. She had found his coat at the bottom of the stairs, folded with care on a dry patch of concrete. She had found his notebook beside it, open to a page with a circle drawn around the sketch of a small bone disc. She had never found Morris. Her radio crackled against her collar. "Quinn, units six minutes out. Repeat, six minutes." Tomás reached a maintenance fence built into the side of the bridge. Rusted signs warned about electrical hazards and trespass. He reached into his coat pocket and produced a flat token carved from bone. Quinn saw the disc catch the light. It matched the sketch in Morris's notebook down to the notch cut into its edge. She stopped ten paces short and raised one hand. "Where did you get that?" Tomás slid the token into a slot set into the fence post. Metal ground against metal inside the post. "You do not want the answer out here." "I want it wherever you give it." "I have a patient with venom in his blood and an hour of useful life left in him. Your questions can queue behind his heart." "Venom from what?" "From something your reports call an exotic animal because the other words upset the typists." The fence released a section of panel with a clunk. Behind it, a concrete stairwell dropped into darkness. Warm air rose from below and carried cinnamon, hot iron, sulphur, and the sweet rot of overripe fruit. Voices drifted up the stairs in a dozen accents. Glass chimed against glass. Something heavy dragged across stone and then stopped. Tomás stepped onto the first stair. "Stay on your side of the fence, Detective." "That token. Show me again." "You saw enough." "Morris drew that token the night he vanished." Tomás paused with his hand on the rail. The medallion at his throat swung and tapped the buttons of his shirt. "Then you understand the fence." "I understand you have evidence linked to a missing officer." "I have a key. It stops being a key once your evidence bags eat it." The panel began to slide back into place on a hydraulic arm. Tomás stepped down another stair and the darkness took his legs. Quinn pulled a sealed evidence pouch from her inside pocket. Rain spotted the plastic at once. Inside sat a bone token she had lifted from the hidden room at The Raven's Nest an hour earlier, logged, photographed, and sealed under Morris's case number. The token had come from a drawer packed with gauze, suture kits, and bottles without labels. Her seal held the chain of custody together. Her seal also held the door shut. She looked at the radio. She looked at the panel as it ate the gap inch by inch. She looked at the evidence pouch and at her watch, where the second hand swept past the water trapped under the glass. "Control, Quinn. Suspect entered a service access under the canal bridge off Chalk Farm Road. I have no visual on the interior. I need units at the fence now." Static answered her, then a voice with half its consonants stripped out. "Quinn, hold position. Repeat, hold position. Units en route." Tomás called up from below, his voice flattened by concrete. "The market moves at the full moon, Detective. That gate opens for the next fool in the queue and then this station belongs to pigeons and rainwater again." "You expect me to let you walk into a black market with that bag?" "I expect you to choose between your missing man and your procedure. You have about eight seconds to make the choice with the door." Quinn tore the evidence seal with her teeth. The plastic split and the bone token dropped into her palm, warm from her body heat. She stepped to the fence post and drove the token into the slot before the panel completed its seal. The mechanism swallowed the token and spat it back into a return tray. The panel froze, shuddered, and reversed direction. Quinn ducked through the gap and felt the panel brush the back of her coat as it changed direction again behind her. The street noise cut off mid-note. The radio gave one last burst of static and died against her collar. The stairwell dropped in switchbacks, each landing lit by caged bulbs that painted the concrete amber. Water dripped from pipes overhead and struck her shoulders through her coat. Tomás stood two landings below, watching her descend. "You broke your own seal." "Log it in your patient notes." "Your backup will love the paperwork." "They can read it to me at the hearing." She reached his landing and followed him down the last flight. The stairs opened onto the platform of an abandoned Tube station beneath Camden, but no trains slept in the tunnel mouths and no adverts hung on the tiled walls. Stalls filled the platform edge to edge, built from scaffold poles, theatre flats, coffin lids, and sheets of hammered copper. Lamps burned inside bottles of blue and green glass. Vendors stood behind counters stacked with jars of teeth, folded maps that shifted their coastlines under the lamplight, vials of black sand, silver instruments laid out on velvet, and cages draped with cloth that bulged and settled in rhythm. Heads turned toward Quinn. Conversations dropped into silence one stall at a time. A woman with ink covering her throat closed a ledger with a snap. A man in a porter's uniform slid a tray of labelled bottles under his counter and rested both hands on the wood, palms down. Tomás walked into the crowd with the medical bag still sealed against his side. A gap opened around him where Quinn got none. She stepped off the last stair, felt the heat of the platform close over her wet clothes, and saw the Saint Christopher medallion flash between two stalls as Tomás turned toward a counter piled with green glass vials. Quinn pushed between the stalls and kept him in sight.
