AI The pavement spat rainwater under Harlow Quinn’s boots as she rounded the corner, her breath steady despite the burn in her lungs. The suspect—a lanky figure in a dark hoodie—darted between the shadows of Soho’s back alleys, his silhouette flickering under the sickly glow of a dying streetlamp. She’d been tailing him for twenty minutes, ever since he’d slipped something small and metallic into the pocket of a known fence outside The Raven’s Nest. The green neon sign of the bar still buzzed in her peripheral vision, its light bleeding into the wet cobblestones.
She pushed harder, her leather watch strap biting into her wrist as she timed her steps. The suspect glanced back, his face half-hidden, but not before she caught the glint of fear in his eyes. Good. Fear made people sloppy.
He veered left, into a narrow passage reeking of stale beer and something fouler—rotting meat, maybe, or the copper tang of old blood. Harlow didn’t hesitate. She took the turn at a sprint, her shoulder grazing the damp brick. The passage dead-ended at a rusted fire escape, its ladder already swinging as the suspect hauled himself up. She cursed under her breath, scanning for another route. There—a black door, half-hidden behind a stack of sodden crates. The wood was warped, the paint peeling, but the brass handle gleamed as if recently polished.
She wrenched it open.
The stairs beyond were steep, the air thick with the scent of damp earth and something else—ozone, maybe, or the faintest whiff of sulphur. The suspect’s footsteps echoed below, rapid, desperate. Harlow descended, her free hand trailing the wall for balance. The stone was slick, the light fading with every step until she was swallowed by darkness. Then, a flicker . A single bulb, bare and swinging, cast jagged shadows across the landing.
The underground opened up before her.
The Veil Market.
Harlow’s pulse spiked. She’d heard whispers of this place—an abandoned Tube station repurposed as a black market for the city’s underbelly. The kind of place where the Metropolitan Police’s jurisdiction ended and something older, darker, began. The suspect had vanished into the labyrinth of stalls, their canopies patched together from mismatched fabrics, their wares glowing faintly under the dim, erratic lighting of lanterns and candles.
She stepped forward, her boots crunching on something brittle—bone, maybe. The entry requirement, if the rumours were true. A bone token. She didn’t have one.
A hand clamped around her wrist.
“Lost, Detective?”
Harlow twisted, her other hand flying to the pepper spray at her belt. Tomás Herrera stood there, his dark curls damp from the rain, the Saint Christopher medallion at his throat catching the light. His grip was firm but not threatening. She exhaled sharply .
“Herrera. You’re a long way from your clinic.”
“And you’re a long way from your precinct.” His thumb brushed the scar on his forearm, a habit she’d noticed before. “This isn’t your turf.”
“He’s my suspect. Saw him pass something to Jimmy Cole outside the Nest. Small, metallic. Could be a weapon.”
Tomás’s jaw tightened. “Or a key. Or a charm . Or a hundred things that’ll get you killed down here.”
“Then help me.”
A beat. The market’s hum—low murmurs, the clink of glass, the rustle of fabric—pressed in around them. Tomás released her wrist, his fingers lingering a second too long. “You don’t understand what you’re walking into.”
“Then enlighten me.”
He gestured to the stalls. “That one sells cursed jewellery. That one, bottled memories. The bloke in the corner? He trades in names. Real ones.” His voice dropped . “And over there—” He nodded toward a shadowed alcove where the air seemed to shimmer. “That’s where they deal in things that aren’t meant to be dealt in.”
Harlow’s gaze flicked to the alcove. The suspect was there, hunched over a table, his hood now pulled back to reveal a gaunt face and a necklace of small, gleaming teeth. He was talking to a figure draped in a cloak the colour of dried blood.
“He’s mine,” she said.
Tomás blocked her path. “You don’t have a token. They’ll know you don’t belong.”
“I’ll take my chances.”
“You’ll get us both killed.”
She sidestepped him. “Then stay here.”
The market seemed to sense her intent. The murmurs died. Heads turned. A woman with eyes like polished obsidian watched her, lips curled into something that wasn’t quite a smile . Harlow ignored the prickle at the back of her neck and strode forward, her hand resting on the baton at her hip.
The suspect spotted her. His eyes widened, and he bolted, knocking over a table laden with glass vials. They shattered, releasing a cloud of iridescent vapour that made her vision swim. Harlow coughed, waving a hand in front of her face, but didn’t slow down. She vaulted over the debris, her boots skidding on the slick stone.
Tomás was suddenly beside her, his voice a growl. “I told you this was a bad idea.”
“Shut up and keep up.”
They wove through the stalls, the suspect dodging between shoppers with the agility of a rat. Harlow’s lungs burned, her muscles screaming, but she didn’t let up. The suspect ducked behind a curtain of beads, and she followed, shoving through them hard enough to send them clattering to the ground.
The space beyond was a dead end. A single lantern cast long shadows across the walls, which were lined with shelves of jars. Inside each jar, something moved. Harlow didn’t look too closely.
The suspect was gone .
Tomás skidded to a halt beside her, his chest heaving. “There’s another exit. He’ll be heading for the old platform.”
Harlow didn’t answer. Her gaze was locked on the jars. One of them pulsed with a faint, sickly light. Inside, a shadow coiled like smoke.
“Quinn.”
She tore her eyes away. “The platform.”
They backtracked, the market’s denizens watching them with open hostility now. A man with too many teeth bared them in what might have been a grin. A child—no older than ten—held out a bone token, her small hand trembling. Harlow shook her head, and the girl’s face fell.
The platform was a relic of the station’s past, its edges crumbling, the tracks beyond swallowed by darkness. The suspect stood at the far end, his back to them, his hands clutching the railing as if considering a dive into the abyss below .
Harlow slowed, her baton now in her hand. “Police. Step away from the edge.”
The suspect turned. His face was gaunt, his cheeks hollow, but his grin was wide, too wide. “Took you long enough, Detective.”
Tomás grabbed her arm. “That’s not him.”
Harlow’s blood turned to ice. The voice was wrong. Too deep. Too smooth. And the eyes—
The suspect’s eyes were black. Not dark. Not shadowed. Black. Like oil. Like the void.
“Run,” Tomás hissed.
The thing that wasn’t the suspect lunged.
Harlow didn’t think. She swung her baton, the crack of it connecting with something solid, but the figure didn’t flinch. It laughed, a sound like breaking glass, and swiped at her. Its nails were long, curved, and they sliced through her coat like it was paper.
She stumbled back, her breath ragged. Tomás was already moving , snatching a lantern from a nearby stall and hurling it. The glass shattered against the thing’s chest, and for a second, it screamed, its body wreathed in flame. Then the fire died, snuffed out as if by an unseen hand.
The thing advanced.
Harlow’s back hit the wall. Nowhere to go. Nowhere to run. The thing’s breath was hot, reeking of decay. “Detective Quinn,” it whispered, her name a curse on its lips . “We’ve been waiting for you.”
Tomás shoved her aside, a scalpel—where the hell had he got a scalpel?—flashing in his hand. He slashed, and the thing hissed, recoiling. Black blood spattered the stone.
“Move!” Tomás grabbed her wrist, yanking her toward the stairs. Behind them, the thing shrieked, the sound echoing through the market like a physical blow.
Harlow didn’t look back. She ran, her boots pounding up the steps, her heart hammering against her ribs. They burst into the alley, the rain a cold shock against her skin. The passage was empty. The door to the market swung shut behind them with a final, echoing thud.
She bent over, her hands on her knees, gasping. “What the hell was that?”
Tomás didn’t answer. His face was pale, his medallion cold against his skin. He stared at the door, then at her. “You shouldn’t have followed him.”
Harlow straightened, her jaw set. “That thing knew my name.”
“They all know your name, Detective.” His voice was grim. “You’ve been asking too many questions. About the Nest. About the things that happen there.”
She wiped the rain from her face. “And what things are those, Tomás?”
He didn’t answer. Instead, he reached into his coat and pulled out a small, metallic object. A bone token. “You’ll need this if you’re going back.”
Harlow stared at it. “I’m not done with this.”
“Yes, you are.” He pressed the token into her hand. “For tonight. But if you go back, you go alone. And you don’t come looking for me.”
The rain fell harder, the drops like needles against her skin. She closed her fingers around the token. “Why give me this, then?”
Tomás’s gaze was steady. “Because next time, you might not make it out.”
A distant scream echoed from below, cut short. Harlow’s grip tightened.
The door to the market creaked open, just a crack. Something slithered through the gap, a shadow with too many limbs, too many eyes.
Tomás grabbed her arm. “Now, Detective. *Now.*”
