Cold rain needles stung Harlow’s cheekbones. She vaulted a toppled wheelie bin, her boots splashing through an oil-slicked puddle that reflected the amber glow of Camden’s streetlights. Ahead, a shadow detached itself from the brick wall of a shuttered pub. Tomás Herrera. Harlow lengthened her stride, her lungs burning with the damp night air. Eighteen years on the Met, and her knees still handled the concrete impact without complaint. She wiped water from her closely cropped salt-and-pepper hair, locking her brown eyes on the leather medical bag bouncing against Herrera’s hip. "Stop! Police!" Herrera didn't look back. He vaulted a low iron railing, his short dark curls plastered to his forehead. The collar of his jacket flared open, and a silver Saint Christopher medallion flashed against his olive skin before disappearing beneath his chin. Harlow took the railing in a clean, military-precise hurtle. She landed on the balls of her feet and snatched the radio clipped to her lapel. "Control, this is DS Quinn. In foot pursuit of a male suspect heading north off Chalk Farm Road. Requesting units to intercept at the canal." Static hissed from the receiver, broken and useless. She cursed, releasing the button. A glance at the worn leather watch on her left wrist gave her the time: 02:14. No pedestrian traffic to block him. Just slick cobblestones, overflowing gutters, and the rumble of distant thunder. Herrera cut left into a narrow cul-de-sac that reeked of rotting cabbage and wet soot. Harlow rounded the corner two seconds behind him, her baton already drawn and extended with a sharp metallic snap. The alley ended at a chained concertina gate fronting a derelict brick structure. Faded red tiles lined the entryway, framing a rusted London Underground roundel whose station name had been pried off decades ago. Herrera slammed against the iron bars. He threw a frantic look over his shoulder, his warm brown eyes wide. He tugged at the heavy padlock, his left sleeve riding up to expose the jagged pale scar running the length of his forearm. Harlow slowed to a deliberate walk, blocking the alley's mouth. Rain dripped from her sharp jawline. She kept her baton angled down, ready to strike. "Nowhere to go, Tommy. Drop the bag." Herrera’s chest heaved. He pressed his back against the rusted iron, clutching the leather strap of his kit with white-knuckled fingers. "I didn't steal anything, Detective. Leave it alone. Turn around and walk back to Soho." "You bolted from the back door of The Raven's Nest the second you saw my warrant card. Innocent men finish their pints." "The NHS struck me off two years ago. Carrying suture kits and restricted painkillers looks bad on paper." "You aren't carrying paracetamol in that satchel." Harlow took two measured steps forward. "Three years ago, DS Morris bled out in a warehouse two miles from here. The coroner found traces of an unknown compound in his wounds. The exact same compound forensics pulled from a stained rag behind Silas' bar last week. Open the bag." Herrera swallowed hard. His fingers slipped from the bag's strap and dived into his trouser pocket. "Hands where I can see them!" Harlow lunged forward, raising the baton. Herrera pulled out a flat, circular disc the colour of old ivory. He jammed it into a hollow recess in the brickwork beside the rusted gate. The air pressure in the alley plummeted. Harlow’s ears popped. The heavy padlock didn't click open; it dissolved into a swirl of grey ash. The iron gate swung inward without a screech, revealing a spiral staircase descending into thick, violet-tinged gloom. Harlow froze mid-stride, her boot hovering over a puddle. A tall figure stepped out from the shadows of the stairwell. A heavy wool coat hid the doorman's frame, and a wide-brimmed hat shadowed his face, save for a pair of eyes that reflected the streetlamp like a cat's. He extended a gloved palm. Herrera slapped the pale disc into the doorman's hand. "Bone's good," the doorman rasped, his voice grinding like gravel under a tyre. "Full moon's three nights off. You're cutting your supply runs close, Doctor." "Had an unscheduled detour." Herrera slipped past the giant and started down the steps. "Herrera! Halt!" Harlow sprinted the remaining ten feet. She reached the threshold just as the iron gate swung shut. She threw her weight against the bars, expecting the cold bite of rusted metal. Instead, a jolt of static electricity blasted through her palms, knocking her back a step. Her fingers tingled, numb to the knuckles. Through the iron lattice, the stairwell vanished. Solid brick replaced the empty space, covered in soggy concert posters and fresh graffiti. Harlow stared at the wall. Her breath plumed in the cold air. She dropped her gaze to the wet pavement beside her right boot. Half-submerged in a puddle of black rainwater lay a second ivory disc. It must have fallen from Herrera's pocket when he yanked the first one out. She crouched and picked it up. The material wasn't plastic or wood. Fine porous grain ran through the centre, cold and heavy in her palm. Bone. Carved with concentric rings that made her eyes ache if she stared straight at them. Her radio crackled to life, the signal suddenly crystal clear. "DS Quinn, this is Control. Copy your last? We lost your GPS ping for a moment. Over." Harlow looked from the radio to the recess in the damp brickwork. Morris's lifeless face flashed in her mind—the bloodless skin, the shattered service weapon, the closed investigation file stamped *Unexplained*. She didn't reach for the radio button. Harlow stood, her posture snapping back to rigid military precision. She pressed the bone token into the stone slot. The graffiti-covered brick shimmered like heat haze over summer tarmac. The illusion peeled back, exposing the rusted iron gate and the giant in the wool coat. The doorman looked down at her. His nose twitched, nostrils flaring as he took in the scent of wet wool and gun oil. "Met copper," the giant growled, blocking the stairs. "You're off your beat." Harlow didn't blink. She plucked the bone token from the wall and held it up between two fingers. "Entry requirement met. Step aside, or I'll haul you in for obstructing an officer." The doorman let out a dry, rattling laugh that smelled of sulphur. He stepped back into the alcove, sweeping an arm toward the spiral stairs. "Your funeral, Detective. The Veil Market doesn't recognise the Queen's peace." Harlow holstered her baton, though she left the strap unclipped. She stepped past the doorman and descended into the earth. The spiral stairs wound down far deeper than the standard Northern Line platforms. The damp smell of London clay gave way to a thick cocktail of ozone, burnt sage, and copper. Whispering voices echoed up from the shaft, growing into a dull roar of haggling crowds. She exited the stairwell onto a wide, tiled platform. The abandoned Tube station stretched out before her, bathed in the glow of floating glass orbs filled with bioluminescent green liquid. Rusted tracks ran down the centre pit, bridged by wooden planks that connected two platforms crammed with canvas tents and iron cages. Shoppers brushed past her. A woman in a pinstripe suit haggled with a vendor whose skin had the grey, pebbled texture of river stone. Across the tracks, an apothecary weighed violet powder on brass scales, surrounded by jars of preserved organs that twitched in their brine. Ahead, a flash of dark curls bobbed through the crowd near an archaic brass kiosk. Herrera. Harlow adjusted the collar of her jacket, hiding her radio, and stepped off the platform edge into the press of bodies.
