AI The heavy iron gate shrieked, resisting my boot, but I shoved it aside and felt the bitter London rain turn into a freezing torrent. My quarry bolted across the slick cobblestones of the alleyway, a shadow against the dim orange glow of the streetlamps near Camden. I counted his strides. Three, four, five. He was fast, favouring his right leg, but he lacked the discipline for a sustained crawl.
"Stop right there, Herrera!"
He didn't flinch, just veered hard left, vaulting over a stack of rotted wooden pallets. He was heading for the old Northern Line descent. I drew my service pistol, the cold steel biting into my palm, but held my fire. A dead suspect wouldn't lead me to the source of the recent disappearances, and I needed him tied to the mess I’d been tracking for weeks.
I slammed onto the pavement, the impact jarring my teeth, and sprinted after him, my own breaths hitching in the damp evening air. Ahead, the entrance to the abandoned tube station gaped like a jagged, black wound in the earth. The air here tasted of ozone and ancient, stagnant rot.
"You have nowhere to go, Tomás! The station is blocked!"
He didn't answer. He just plunged into the dark.
I reached the threshold, my pulse hammering a frantic rhythm against my ribs. I flicked on my torch, the beam slicing through the gloom to reveal graffiti-covered tiles and the rusted remains of a turnstile. My worn leather watch showed midnight. Somewhere in the deep, a low hum vibrated through the soles of my shoes, rhythmic and aggressive, like a heartbeat.
I hovered on the edge of the stairwell. My gut twisted, that familiar , unwelcome prickle of warning I hadn't felt since the day I lost Morris. This place was wrong. It defied the logic of city planning, smelling of charcoal and burnt ozone, an olfactory marker for those who traded in things that didn't play by the rules of biology. I stepped down, my boots crunching on crushed glass and dry, brittle bones.
The further down I descended, the more the air shimmered , thick with a static charge that raised the hair on my arms. The descent spiralled into a vast, cavernous hall where the old rusted tracks once laid. Now, the station played host to the Veil Market. Neon strips, stolen from better parts of London, cast erratic pulses of emerald light across a labyrinth of makeshift stalls draped in heavy, velvet fabric.
I kept my back to the wall, scanning the crowd. It wasn't a human crowd. Figures clad in layered, stained cloaks slunk through the aisles, their movements twitchy and unnatural. Someone sat on an overturned milk crate, selling jars filled with swirling, translucent smoke, while another barked demands for a bone token from a terrified-looking courier.
Herrera was nowhere to be seen.
"You're a long way from the precinct, Detective."
The voice slithered out from the dark, cold and sharp. I spun, sweeping my torch until the beam locked onto a broad-shouldered man standing in the shadow of a crumbling pillar. He leaned against a rusted support beam, arms crossed over a torso draped in dark leather.
"I’m looking for a man. Hispanic, curly hair, walks with a slight limp."
"Everybody in the city is looking for someone, Harlow. It's the primary export of this miserable island."
I took a predatory step forward, the gun held steady at my side.
"Don't play word games. I saw him head this way. If he’s here, he’s in breach of three city ordinances and potentially a breach of international law, depending on what he’s carrying."
"The law?" The man let out a dry, rattling laugh, his eyes shifting a shade of unnatural, reflective silver. "The law died in these tunnels long before you started pinning badges to your coat. You're trespassing in a space that doesn't acknowledge your authority."
"I don't need acknowledgement. I need a confession."
I pushed past him, my ears straining for the sound of Herrera's ragged breathing. I navigated a tight corridor formed by shelves stacked high with dried herbs and rusted, serrated blades. The heat here was suffocating , a heavy, cloying humidity that clung to my skin. I passed a table where a woman with elongated, spider-like fingers carefully stitched a glowing, pulsing organ into a wooden doll. She didn't look up; she just clicked her teeth, a sound like dry wood snapping.
I turned a sharp corner and saw him.
Herrera stood at a stall draped in mismatched silks, his hand pressed against his chest over the faint outline of a circular medallion. He was arguing with an elderly vendor whose face looked like a topographic map of scar tissue.
"I need it now," Herrera whispered, his voice desperate . "She's fading, and the standard infusions aren't taking."
"The cost for that requires more than mere currency, boy," the vendor hissed, pulling a small, corked vial of shimmering, violet liquid from an iron box. "A piece of your memory. A clear, childhood one. Best if it involves someone you haven't seen in a long time."
I didn't wait any longer. I lunged, closing the distance between us in three long, silent strides. I grabbed Herrera by the shoulder and spun him around, my weapon pressed into his side.
"End of the line, Tommy."
His eyes widened , reflecting the sickly green glow of the market. He looked at me, then at the vial, then back at the dark, crowded aisles. His hands trembled , his left forearm marked by that jagged, white scar.
"Quinn. You don't understand. If I stop, if I let the symptoms progress, it won't just be me. It'll be everything she touched."
"I don't care about your medical drama, Herrera. You're coming to the station. You're going to talk about the warehouse on Wapping, and you're going to tell me exactly how you managed to burn clean a crime scene that should have left a dozen bodies."
"I didn't burn it," he spat, his voice dropping to a frantic, low hum . "I saved them. From things you can't even perceive in your fancy, lit-up world."
"Save the lecture for the DA."
I reached for my cuffs, but the atmosphere in the cavern dropped ten degrees in a single heartbeat. The market attendees, who had been busy with their grotesque trades, suddenly fell silent. Every head in the station turned toward us. The woman with the thin fingers stood up, her shadows growing long and reaching across the floor like oily, predatory limbs.
"The Detective is persistent," the creature said, her voice sounding like a thousand distant whispers . "But she is also very , very fragile."
Herrera looked at the crowd, then at me. His face went pale.
"You shouldn't have followed me, Harlow."
A low, guttural roar echoed from the deeper, darker tunnels behind the stalls. The ground shuddered. Dust rained from the subway ceiling, coating us in a layer of grey, suffocating silt.
"What is that?" I gripped my piece tighter, my knuckles white.
Herrera didn't look at me. He stared back into the darkness of the tunnel mouth, his breath coming in short, ragged bursts.
"That's the reason I left the hospital," he said. "And it's the reason neither of us is walking out of here."
The crowd parted. A massive, hulking shape detached itself from the gloom , its hide shimmering with scales that sucked the light from the air. It wasn't human. It was something starved, something angry, and it was looking directly at the silver badge pinned to my jacket. The beast lunged, and the sound of iron scraping concrete filled the cavern as the market went chaotic .
