Rain slashed the Camden cobblestones. Water poured from the canvas awnings of closed market stalls, turning the narrow alleys into slick, treacherous ravines. Detective Harlow Quinn ignored the cold seeping through her wool coat. She kept her brown eyes locked on the figure darting through the shadows ahead, maintaining a relentless, driving pace. Eighteen years of service in the Metropolitan Police ingrained a military precision into her stride. She moved with rigid efficiency, her boots landing flat and hard against the wet pavement, avoiding the deepest puddles, cutting corners sharp tight against the brickwork. Water flattened her closely cropped salt-and-pepper hair against her scalp. She checked the worn leather watch on her left wrist without breaking stride. Midnight. The full moon remained hidden behind a thick blanket of storm clouds, leaving the labyrinth of the market illuminated only by flickering halogen security lights. Ahead of her, Tomás Herrera moved with desperate speed. His boots slapped the mud. He hurdled a discarded wooden pallet, slipped on the landing, and slammed his shoulder into a brick wall. He pushed off immediately. Under the harsh glare of a streetlamp, the rain plastered his short curly dark brown hair to his forehead. His olive skin shone with a mixture of rainwater and sweat. Quinn closed the distance. The chase had started two hours ago in Soho. She had planted herself across the street from The Raven's Nest. The bar's distinctive green neon sign had cast an acidic glow over the puddles. Through the rain-streaked windows, she had observed the interior, noting the old maps and faded black-and-white photographs plastered across the walls. She had watched Herrera approach the bookshelf, slide a heavy tome aside, and vanish into the hidden back room. When he finally emerged and slipped out the rear fire exit, she followed him north to Camden. She knew his file. Born in Seville, Spain. Former NHS paramedic. Stripped of his license after an investigation uncovered unauthorized, bizarre medical treatments administered to patients with unexplainable ailments. Herrera ducked into a dead-end alley cluttered with industrial dumpsters beneath a rusted railway bridge. He hit the chain-link fence at the rear, fingers hooking into the metal diamonds. Quinn drew her weapon and stepped under the archway of the bridge. Her sharp jaw set. She kept the muzzle of her Glock lowered but ready. No more running, Herrera. Turn around. Herrera froze against the fence. He let go of the wire. He turned slowly. His chest heaved. A heavy silver St. Christopher medallion swung from his neck, catching the faint light. He raised his hands. As his wet jacket sleeve retreated, a jagged white scar on his left forearm stood stark against his skin—the remnant of a knife attack he refused to explain to the local constabulary. You need to step back, Detective. You lack the context for this pursuit. Put your hands on your head and interlock your fingers. Herrera backed toward the shadow of a massive industrial dumpster. His warm brown eyes darted. He calculated the distance between them, analyzing the geometry of the tight space. My patients require care. Medical care your hospitals cannot provide. I leave now, or people die. You lost your license for malpractice. You operate an unlicensed clinic for a criminal syndicate. Hands on your head. He lunged sideways. He grabbed the release lever of the industrial dumpster and hauled it down. The massive metal bin tipped forward. A cascade of rotting vegetables, glass bottles, and stagnant black water flooded the alley floor between them. Quinn vaulted backward. Glass shattered against her boots. Herrera used the distraction. He scrambled over the top of the fallen dumpster, vaulted the chain-link fence, and dropped into the deep trench of the railway embankment on the other side. Quinn holstered her weapon. She scaled the fence in three fluid motions, swinging her legs over the top of the wire and dropping into the mud below. Herrera sprinted along the tracks. He veered right, disappearing into the mouth of an abandoned Tube station. Iron gates rusted into a perpetual open maw commanded the entrance. Faded enamel signs pointed into absolute blackness. Quinn halted at the threshold. Cold air rushed up from the subterranean depths. It carried an unnatural chill. It smelled of ozone, copper, and damp earth. A sharp spike of adrenaline pierced her chest. Three years ago, she had followed DS Morris into a similar darkness. They had tracked a murder suspect into an abandoned subterranean reservoir. She remembered the metallic stench of the air. She remembered the impossible shadows stretching across the wet concrete. She remembered Morris bleeding out from wounds no human weapon could inflict, tearing his throat out while the perpetrator dissolved into mist. The official report cited an animal attack. Quinn knew the truth hid in the spaces between the lines. She gripped the textured handle of her sidearm. She stepped into the descent. The transition erased the ambient sounds of the city. The rain faded into a muffled hum, replaced by the rhythmic dripping of water deep within the station. Broken escalators stretched down into the abyss, locked in place by decades of rust. Quinn descended the metal steps. Her rubber soles made no sound. At the bottom of the escalator shaft, the tunnel opened into a wide, vaulted concourse. Phosphorescent fungi clung to the cracked ceramic tiles lining the walls, casting a sickly pale blue light over the platform. Herrera stood at the far end of the concourse. A massive iron bulkhead blocked the tunnel. A hulking figure draped in a patchwork leather coat stood in front of the door. Quinn pressed her back against a tiled pillar. She observed. The entity blocking the door leaned forward. The hood fell back, revealing a face devoid of eyes, covered entirely in thick, rippling scar tissue down to a lipless mouth. Full moon tonight, flesh-mender. The market lies below. Present the toll. Herrera unzipped the breast pocket of his jacket. He withdrew a long, carved object. A bone token. I require passage to the apothecary stalls. The guardians huge hands closed over the bone token. The air pressure in the concourse dropped. The iron bulkhead groaned, sliding upward on rusted tracks. A cacophony of sound spilled from the gap. The Veil Market revealed itself. Dozens of makeshift stalls constructed from scavenged train parts and glowing crystal lined the platform of the buried tunnel. Patrons in elaborate robes and tattered modern street clothes bartered over glass vials filled with swirling luminescent liquids. Smoke in unnatural shades of violet and crimson drifted through the air. The scent of roasted meat mixed with burning sulfur. Herrera adjusted his collar. He stepped under the heavy iron door and vanished into the bustling crowd of the supernatural black market. The guardian gripped the release lever, preparing to seal the bulkhead. Quinn stood motionless behind the pillar. Her breathing slowed. The hum of the unnatural energy vibrating through the underground station rattled her teeth. Every instinct screamed at her to retreat, to return to the surface, to call for backup that would never arrive. This place operated under different laws. A single misstep here meant suffering the same fate as DS Morris. She thumbed the safety off her Glock. She tightened her grip on the grip until her knuckles turned white. She stepped away from the pillar, leaving the shadows behind, and walked directly toward the closing iron door.
