AI Rain slams into Harlow’s collar, seeps through the wool of her blazer, turns Camden’s pavements into slick, garbage-strewn skating rinks. She runs with the military precision drilled into her first during army basic, then 18 years of Metropolitan Police service, boots slapping hard enough to push through standing puddles that soak her socks. Five meters separate her from Tomás Herrera, the former NHS paramedic who’d turned up on her radar six months prior, treating wounded people no hospital would touch, the same man she’d staked out at Silas’ Raven’s Nest bar for three straight nights before he spotted her unmarked car and bolted.
The green neon of the Nest’s Soho sign faded an hour back, but Harlow can still picture it, flickering over the bar’s walls lined with tattered maps and faded black-and-white photos of old London stage acts. She’d first spotted Tomás slipping out of the Nest’s hidden back room, the one accessible through a fake bookshelf, two other members of the clique trailing behind him, and she’d known he had answers. Answers about the three unidentified men fished out of Regent’s Canal with their throats torn open by something that wasn’t human. Answers about her partner, DS Morris, who died in a derelict Camden warehouse three years prior, no wounds on his body, just a wisp of blue light that vanished before forensics could process the scene.
Tomás glances over his shoulder, his short curly dark hair matted to his forehead, and his Saint Christopher medallion bounces against the chest of his waterlogged hoodie. Harlow sees the scar along his left forearm, the pale, thick line from a knife attack, flash as he grabs the top of a chain-link fence separating a closed record shop from a kebab house, hauling himself over and landing hard on the other side. She copies the move, her 5’9” frame clearing the fence with inches to spare, and when she lands, her worn leather watch—frayed strap, scratch across the crystal , a birthday gift from Morris three days before he died—slaps against her left wrist, a quiet reminder of what’s waiting if she loses him.
He cuts down an unlit alley, the brick walls streaked with mold and graffiti, and Harlow pushes her pace, lungs burning, the cold rain cutting into her brown eyes. She draws her taser from her hip as she rounds the alley’s mouth, and skids to a halt ten feet from Tomás, who’s parked in front of a rusted metal grate set into the alley’s rear wall. The grate covers the entrance to an abandoned Tube station, the same one locals whisper about, the one that closed in the 70s after a string of mysterious disappearances. Tomás yanks the grate’s lock free, the metal screeching loud enough to cut through the rain, and he heaves it open, dark air that smells of burnt sugar and iron curling up into the night.
Don’t come down here, Quinn. You don’t know what’s waiting for you.
Harlow levels the taser at his chest, her sharp jaw set, finger hovering over the trigger. I don’t need to know what’s down there to arrest you. I have you on assault, illegal distribution of prescription medication, accessory to three counts of murder. I can put you away for life.
Tomás shakes his head, his warm brown eyes wide, not with guilt, with fear. Those murders aren’t on us. We didn’t dump those men. We were trying to stop whatever did. He pulls a small, smooth chip of white bone from his hoodie pocket, holds it up between his thumb and forefinger. The Veil Market’s down there. You know what that means? No cops. No humans who don’t belong. You can’t cross the threshold unless you have a bone token. The wards tear apart anyone who tries.
Harlow adjusts her grip on the taser. Some cheap parlor trick. You think that scares me?
A rat scurries past her boot, drawn to the half-eaten burger wrapper floating in a puddle, and it launches itself toward the open grate, straight for the dark tunnel. A flash of electric blue light blooms at the tunnel’s mouth, and the rat vanishes mid-jump, nothing left but a wisp of acrid smoke that drifts up to Harlow’s nose. The smell hits her like a punch to the chest. She’d breathed that exact scent, sharp and wrong and burnt, in the warehouse where she found Morris, his radio crushed under his hand, no bullet wounds, no cuts, just that same blue light fading from his forehead.
Her hand shakes. She’d spent three years writing off that light as a trick of the dim warehouse lights, a hallucination from the shock of finding her partner dead. The force had written Morris’s death off as a heart attack, closed the case within a week, but Harlow knew better. She’d seen the light.
Tomás leans against the grate’s edge, his voice softer now, like he knows exactly what she’s remembering. That’s the same light that killed Morris, isn’t it? I know you’ve been chasing that lead for years. You think we had something to do with it.
You left your medallion in that warehouse. I picked it up, logged it as evidence. You were there.
I lost that medallion outside the Raven’s Nest three months before Morris died. Somebody stole it, planted it to frame me. To frame all of us. He glances over his shoulder into the tunnel, and his whole body tenses, like he can hear something moving down in the dark, something that isn’t human. I can’t explain more up here. If the wrong people see us talking, we’re both dead. If you want the truth about Morris, you come down with me. But you need a token. That’s non-negotiable. The wards won’t care that you’re a cop. They’ll tear you apart just as fast as that rat.
He slips into the tunnel, boots hitting the rusted metal stairs leading down, and pauses, half-hidden by shadow. I’ll leave the grate open for two minutes. If you’re not down here by then, I’m gone. You’ll never get another shot at the truth. The grate creaks shut behind him, slow enough for Harlow to catch, the lock clicking into place only if she lets it.
Harlow stares at the dim opening, the distant glow of pink and orange neon seeping up the tunnel walls, the faint sound of haggling voices, of a bell that rumbles too deep for human ears, the Veil Market’s hum drifting up to her. Up the alley, Camden High Street glows, the wail of a police siren cutting through the rain, two blocks over. She can call for backup. She can seal the grate, wait for the tactical team to show up, end this before she steps into something she can’t walk away from. She can spend another three years chasing ghosts, another three years wondering who killed Morris, why the force buried his case so fast.
She scans the alley’s wet ground, her eyes locking on a small, smooth chunk of white bone half-buried in a puddle ten feet from the grate, the same size and shape as the token Tomás held. She bends, grabs it, and it’s warm in her palm, even after sitting in the cold rain for who knows how long. She tucks her taser back into her hip, holsters her service weapon, and slips the bone token into the pocket of her blazer. The sound of Tomás’s boots fading down the tunnel echoes up to her, the grate’s hinges groaning as it pulls toward a closed lock.
Harlow steps forward, slams her palm against the grate’s edge to stop it from sealing, and swings her legs over the tunnel’s mouth. The cold dark of the abandoned Tube station wraps around her, and she wraps her hand around the first stair’s rusted railing, the bone token heavy in her pocket as she takes her first step into the Veil Market.
