AI The metal ladder ruts dug into Harlow’s palms as she hauled herself over the boarded-up entrance of the old Camden Tube station. Her closely cropped salt-and-pepper hair fell into her eyes as she shifted, and she brushed it back with a quick, sharp motion. She moved with the military precision that had defined her career: three quick pulls, boots hitting damp concrete without a sound. Her left wrist snagged on a rusted nail, the scratched leather of her watch strap rubbing raw against her skin. She ignored the sting, snapping her arm free and adjusting the strap.
The air hit her first: thick with mildew, slow-drying diesel, and a thin, acrid tang of burned sage that clung to the back of her throat. Flickering fluorescent lights buzzed overhead, their glow catching the faded blue and red London Underground roundel peeled halfway off the tiled wall. This was not the standard police crime scene she’d logged a hundred times over.
A figure stepped out from behind a pile of cracked ceramic tiles. Eva Kowalski’s round glasses were askew, freckled cheeks flushed, and she tucked a strand of curly red hair behind her left ear—twice, her fingers fumbling the second time, catching on the frames. Her worn leather satchel bulged with books, the straps frayed where they’d worn through last month.
“Harlow,” she said, voice rough . She gestured toward the far platform. “I found him an hour ago. Called your direct line, not the station.”
Harlow nodded. She’d given Eva the number three months prior, after the woman had reached out about the unsolved death of DS Morris, the partner Harlow had lost three years prior. Eva was an expert in London’s hidden supernatural underworld, the only person Harlow trusted to parse the things that didn’t fit in official police reports.
She followed Eva’s gaze to the slumped figure against the far wall. A man in a tattered black wool coat, shoulders hunched as if he’d been trying to hide from the flickering lights. A pool of dark, iridescent blood spread around his boots, not seeping into the concrete but pooling like liquid mercury . At his feet, half-buried in the grime, was a small brass compass.
Harlow pulled a pair of latex gloves from her duty belt, snapping them tight over her fingers. She knelt, keeping her weight shifted so she didn’t disturb the fine dust coating the platform. The man’s face was pale, skin stretched tight over sharp cheekbones, and his hands were crusted with a fine green patina. The compass was clutched in his right fist, his fingers curled so tight Harlow had to wiggle her gloved thumb between his knuckles to pry them loose.
The first thing she noticed was the verdigris coating the brass casing, the same wear the Shade artisan pieces Eva had shown her last year. The face was etched with looping protective sigils, worn thin at the edges. The compass needle didn’t spin on its axis, pointing instead directly at the thin, clean slice across the man’s chest. A faint whiff of burned sage drifted from the man’s inner coat pocket, the same protective incense Eva had explained Shade artisans burned to ward off unwanted supernatural attention.
“Standard gang hit?” Eva said, leaning against a concrete pillar, her satchel slipping off one shoulder. She pulled a dog-eared paperback from the bag, the cover faded to near-black, the title illegible. “I heard a vendor rift was supposed to open here tonight. Full moon, right? Everyone was supposed to set up stalls. Buy, sell, trade. This guy”—she nodded at the body—“he made those compasses, yeah? The ones that point to rifts.”
Harlow didn’t look up from the compass. The needle quivered slightly in the dim light, its tip glowing faint gold for a split second before fading back to silver. “Why leave the compass?” she said. “If it was a robbery over a high-value enchanted item, you’d take the goods.”
Eva shrugged, tucking another strand of red hair behind her ear. Her glasses slipped down her nose, and she pushed them back with a frustrated huff. “Maybe they fought over it. Maybe he didn’t let them take it. The wound—looks like a shadow blade. Morris’s case, remember? The same clean slice, no blood spatter, no weapon left behind.”
Harlow’s jaw tightened. She’d spent three years replaying Morris’s death: the way the paramedics had found him slumped against a warehouse wall, a single brass compass at his feet, needle pointing directly at his chest wound. She’d written it off as a fluke, a copycat killing that would never be solved. Not this.
She ran a gloved finger along the compass’s casing, feeling the smooth verdigris under her touch. No scratches, no dents, no scuff marks where someone had grabbed it forcefully. “If he’d fought someone for this, there’d be marks on the brass,” she said, turning the compass toward the overhead lights. “He held onto it willingly.”
Eva’s posture shifted, suddenly alert. She set the dog-eared book on the concrete, the pages fluttering slightly in the draft from the broken window at the far end of the platform. “Willingly? Then who killed him? And why?”
Harlow stood, brushing concrete dust off her charcoal trousers, and scanned the platform. The dust was a thin, uniform layer over every surface except around the body and her and Eva’s footprints. No other marks, no scuffs, no signs of someone else entering or leaving. No discarded blade, no dropped bone token—no trace of a killer at all.
She knelt again, this time leaning closer to the body’s inner coat pocket. The fabric was torn open, ragged edges frayed where something had been ripped free. A small, carved bone token lay missing, the same entry requirement Eva had explained for the Veil Market: a chipped badger bone, inscribed with a single rift sigil.
Her gaze dragged upward, to the tiled wall behind the man’s head. A faint, glowing crack sliced through the blue tiles, gold light leaking out before fading to nothing. It was a rift—closed now, as quickly as it had opened.
“Someone came through the rift,” Harlow said, her voice quieter now . “Killed him, left through the same rift. That’s why there are no footprints. No one walked on this platform except us.”
Eva stepped closer, her glasses slipping down her nose again. She reached up to push them back, her fingers trembling slightly . “But why? Why kill him and leave the compass? The rift would have closed as soon as they stepped through. They could have taken the compass, sold it for a fortune.”
“Because they didn’t want the market to open,” Harlow said, picking up the compass and holding it up to the spot where the rift had been. The needle twitched, spinning once before settling back on the man’s chest wound. “This compass points to the nearest supernatural rift. Right now, the only strong energy source is the wound itself. The blade came through the rift, killed him, and went back before anyone could see it.”
She turned back to the torn coat pocket, her fingers brushing the frayed fabric. “The victim had his entry token stolen. The killer let themselves in through the rift, came here to stop the market from opening. They didn’t want anyone using these compasses to find hidden rifts, to tap into the underground market that Morris died investigating.”
Eva’s eyes widened . She leaned in, staring at the compass in Harlow’s gloved hand. “You think this is the same killer?”
Harlow nodded, her sharp jaw set tight. She checked her watch again, the leather strap rubbing her raw wrist, and noted the time: 1:17 a.m. The full moon would be high overhead in less than an hour.
She turned back to Eva, holding up the compass so the overhead lights caught the etched sigils. The needle was still, pointing directly at Harlow’s own chest.
Her sharp jaw tightened, and she checked her watch once more—1:19 a.m., the full moon due to peak in nine minutes. She’d spent three years chasing this killer, the one who’d taken Morris, and now they’d handed her a direct clue.
She pulled her service weapon from its holster, the metal cool against her palm, and scanned the platform again, now looking for any faint glint of gold, any sign of a rift opening. Eva grabbed her satchel, rummaging through the straps before pulling out a small wooden stake and holding it ready.
“We need to secure the perimeter,” Harlow said, her voice sharp, efficient , exactly the way she’d been trained . “Alert every unit in Camden to lock down the Tube entrances. No one enters or leaves this station until we find the rift.”
She turned back to the body, kneeling again to study the compass one last time. The sigils on the face glowed faintly, a quiet reminder of the world she’d spent three years trying to ignore. The killer was here, somewhere, and this time, Harlow wasn’t going to let them get away.
