AI The rain lashed Harlow’s trench coat collar as she hauled open the rusted metal grate covering the manhole, her boots thudding onto damp, mildewed concrete 20 feet below Camden High Street. The full moon hung low over the brick terraces, its silver light spilling through the opening to paint the walls in a pale, ghostly glow—tonight was the full moon, the night the Veil Market moved to this abandoned tunnel, the same night her partner DS Morris had died three years prior. She’d heard the whispers for years: that the market shifted locations with each lunar cycle, that you needed a bone token to slip past the veil between the human world and the realm of magic, that anyone who looked too close vanished without a trace. She’d never believed them—not until tonight.
British Transport Police had called in the Met’s violent crime unit after finding a pool of dark, congealed blood seeping out of a blocked-off tunnel off Platform 13, a section of the line that had been sealed since 1982, after a string of “unexplained disturbances” written off as vandalism. The worn leather strap on her left wrist squeaked as she adjusted her grip on her flashlight, the beam cutting through the dust and fallen plaster to reveal spray-painted letters stenciled on the tunnel wall: VEIL MARKET, the paint still glossy, as if someone had touched it that day.
A young BTP officer, his uniform still damp from the rain, stepped forward, holding out a laminated evidence bag. “Found this by the body, Detective Quinn. Looks like a dog bone, but it’s carved with weird symbols. We ran a forensics check—no prints, no DNA. Just cold, like it’s been buried for years.”
Harlow took the bag, her fingers brushing the plastic. Inside was a cracked wolf bone, its edges worn smooth, the carving matching the sigils she’d memorized from Morris’s case file: the same ones etched into the brass compass sitting in her desk drawer at the station. She slipped the bag into her coat pocket, and the air shifted. The hum of distant chatter bloomed around her, not the muffled traffic of the street above, but a mix of guttural clicks, rolled R’s in a language she didn’ t recognize, and the soft jingle of a bell above a stall door. The tunnel walls no longer looked like cracked concrete—they were draped in frayed velvet , strung with fairy lights that flickered with a blue, otherworldly glow, and rows of wooden stalls lined the path, some stacked with vials of glowing green liquid, others with taxidermied ravens, their eyes pebbled with glass, a vendor selling hand-poured candles shaped like skulls standing beside one stall, haggling with a figure in a long, flowing coat made of shadow.
The BTP officer blinked, staring past her. “Detective? You okay? You look like you’ve seen a ghost.”
Harlow looked back at him, and he was staring at a blank stretch of concrete, no stalls, no velvet drapes, no glowing lights. She’d been seen, the veil had lifted just enough for him to catch a glimpse, but he couldn’t process it. She forced a tight smile, her brown eyes steady as she nodded. “Just tired. Lead me to the body.”
He turned and walked down the tunnel, and Harlow followed, her flashlight beam cutting through the silver moonlight to reveal a small brass compass glinting on the ground near a stack of jewelry boxes. She picked it up, her breath catching in her throat. It was the same compass Morris had been holding when he died, the one she’d taken from the crime scene, the one she’d hidden in her desk for three years. How had it gotten here?
Ahead, a group of officers were huddled around a body, their flashlights pointed down at a stall stacked with enchanted jewelry, a hand-painted sign above it reading JAX’S CURIOSITIES scrawled in ink that looked like it was mixed with dried blood . Detective Inspector Tanner, her direct supervisor for the past year, was leaning over the body, his notebook tucked under one arm, a disgusted frown on his face. He’d been there when she’d submitted her report on Morris’s death, when she’d claimed the killer had not been human, when she’d shown him the sigils and the compass and the weird ash residue on Morris’s hands. He’d transferred her to cold cases a month later, told her she was burnt out, that she needed to stop chasing ghosts.
“Quinn,” he said, not looking up . “You’re not going to believe what we pulled up here. Jax—small-time fence, ran a stall out of a pub basement in Kentish Town—was found with his throat slit. But the weird part? His wallet’s gone, his phone’s gone, but there’s a half-empty bag of heroin on the stall counter. BTP thinks it’s a drug deal gone bad. One of their regulars said he’d been dealing to a new crew out of Kent.”
Harlow shone her flashlight on the body, and her stomach turned. Jax’s throat was torn , not sliced—there were ragged, curved marks gouged into his neck, not the clean, precise incisions a knife would leave. There was no knife on the ground, no trace of a weapon, and the heroin bag looked untouched, half-buried under a pile of small brass trinkets. She knelt down, moving with the military precision she’d honed during her initial police training, crouching low, keeping her flashlight trained on the body first, then the surroundings, always scanning for threats, her salt-and-pepper cropped hair falling forward over her face as she leaned in. She picked up one of the trinkets: a small compass, its casing covered in verdigris patina, the face etched with sigils identical to the ones on the bone token and Morris’s case file. The Veil Compass, exactly as the rumors and her old case notes described it.
“This isn’t a drug deal,” she said, her voice sharp, her brown eyes narrowing as she held up the compass. “That’s a Veil Compass. Jax was selling magical artifacts, not heroin. You can see the sigils on these trinkets—they’re protective wards, against evil spirits, against human attackers. A drug dealer wouldn’t stock this stuff. The heroin bag was planted. Someone wants us to think this is a regular crime.”
Tanner looked up, his brow furrowed , and she could see the doubt in his eyes, the same doubt he’d shown three years ago when she’d told him about Morris’s death. “Harlow, come on. This is Camden. Drug deals go bad here all the time. The wounds could be from a broken bottle, a chair leg—”
“They’re not,” she interrupted, standing up and sweeping her flashlight across the empty stalls. “This wasn’t a human attacker. Look around—these stalls are stripped clean. The vendor who was haggling ten minutes ago is gone, the fairy lights are flickering out, and there’s no sign of a struggle except for the body. Jax was trying to use that compass to call for help, to open a rift to the human world, but someone got to him first. They killed him before he could finish, erased all his records, planted the heroin to lead us astray.”
As she spoke, a soft clicking sound echoed behind her, the sound of claws scraping against concrete. Harlow turned, her flashlight beam catching a shadowy figure standing at the end of the aisle, taller than any human, its shoulders hunched, its hands tipped with long, curved claws. The figure vanished when the beam hit it, leaving only a trail of glowing green dust on the concrete, the same color as the liquid in the vials on the stalls.
Tanner saw it too, his face draining of color, his notebook slipping from his hand to land on the concrete with a soft thud. “What the hell was that?”
“I told you,” Harlow said, her voice quiet but firm, her gaze fixed on the trail of dust leading toward the tunnel mouth. “This isn’t a regular crime scene. Morris died here, three years ago. He was investigating the same thing—this market, the people who sell these artifacts, the ones who want to shut it down permanently. Jax was talking to me last month, said someone had been asking him about the Veil Compass, about the people who ran the market. He said he was scared, that they’d threatened him if he didn’t stop talking to the cops. I told him to come to the station, to file a report. He never showed up.”
She walked over to the stall’s back wall, running her hand over the velvet drape. There was a small slot cut into the wood, filled with chalk sigils identical to the ones on the compass and the bone token. She pulled out her phone, pulling up the photo she’d taken of Morris’s palms, the sigils carved into his skin, the same sigils etched into the slot. They were a perfect match.
“Jax was trying to open a portal through the veil, to get help,” she said, her voice tight with emotion. “But someone got to him first. They didn’t want anyone to know the Veil Market exists, that there’s magic hiding in the cracks of London. They killed him, planted the heroin, and left the compass to make it look like he was just another junkie. Except there’s no junkie here. No one who would buy or sell heroin in a market like this.”
She knelt down again, picking up the Veil Compass, her fingers brushing the verdigris patina. The needle was spinning wildly, then it settled, pointing toward the tunnel mouth, toward the manhole cover above. She followed the needle’s direction, shining her flashlight along the ground, and found a trail of glowing green dust leading out of the tunnel, up the concrete stairs toward the street. The dust was warm under her flashlight beam, almost glowing, and she could smell the burnt sage again, sharp and sweet, clinging to the concrete.
“Tanner,” she said, standing up and slinging her flashlight over her shoulder, her grip tightening on the compass in her pocket. “We need to follow this. This is bigger than a drug deal. This is supernatural, and it’s tied to Morris’s death. The killer is still out there, and they’re going to keep killing until no one knows about the Veil Market anymore.”
Tanner picked up his notebook, his hands shaking slightly , and followed her toward the tunnel mouth. As they stepped back into the abandoned concrete tunnel, the fairy lights vanished, the chatter faded, and the air smelled like mildew and rain again, the Veil Market hidden once more behind the veil. But the trail of dust was still there, leading up the concrete stairs toward the street, and Harlow’s brown eyes glinted with determination as she started up the stairs, the worn leather strap on her left wrist digging into her skin as she moved with the military precision that had carried her through 18 years of decorated police work. She’d spent three years trying to convince everyone that Morris hadn’t died in a regular car crash, that the supernatural was real, that there were people who wanted to hide it. Now she had a crime scene, a trail of evidence, and a suspect who was willing to kill to keep the secret. The evidence didn’t add up, and she was going to find out why.
