You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The floodlights hummed so loud they vibrated in Harlow’s teeth. She stepped over the cracked lip of the abandoned Camden Tube station’s maintenance shaft, her boots sinking into mud that reeked of rot and diesel. Her scuffed leather watch, worn thin at the edges from three years of digging through locked basements and overgrown churchyards, read 2:17 a.m. She’d raided five Veil Market sites in as many months, and this was the first that didn’t reek of burnt sage and stolen spell components. It smelled of bleach. Uniforms fanned out along the tunnel walls, their flashlights bouncing off chipped tile maps of the Northern line. No one moved toward the body slumped against the far wall. They knew she liked to clear the scene herself first, to build her own picture before anyone else’s interpretation clouded it. Her sharp jaw tightened as she closed the distance, the station’s cold seeping through her uniform trousers. The salt-and-pepper crop of her hair brushed the collar of her shirt, the close trim she’d maintained since her army days, before she joined the Met. The man who’d once run this iteration of the Veil Market slumped against a chip in the Camden Town tile, his grey skin stretched tight over high cheekbones. Shade, Harlow registered, the same species that crafted the Veil Compasses she’d spent six months tracking. His hands lay folded over his chest, a small brass compass resting on his palms. Verdigris crept up the compass’s edges, the sigils etched into its face faint in the floodlight’s glow. Mills, the ME who’d handled all her odd death cases since DS Morris died, knelt by the body’s feet, his kit open at his side. He wiped his gloved hands on his scrubs. Time of death checks out between 11 and 13 hours prior. Single stab wound to the heart, should’ve bled out in minutes. Harlow lowered herself to one knee, her weight shifting forward in the smooth, controlled motion of her old military training. She leaned in, her gaze fixed on the stab wound sliced through the Shade’s black wool shirt. The fabric around the cut stayed crisp, no dark stain seeping into the threads. No blood at all, pooled under his body, smeared on his hands, or tracked into the tunnel beyond. Only a faint, rust-colored smudge under his shoulder, thin enough to be a smudge of paint. That’s impossible, Mills said. The wound’s deep enough to nick the aorta. There should be five pints of blood here, minimum. A soft laugh came from the tunnel mouth. Eva Kowalski leaned against the concrete, her round glasses slipping down her nose as she pushed off the wall. Her worn leather satchel bulged with archival texts, its strap cutting into her freckled shoulder. She tucked a strand of curly red hair behind her left ear, the nervous tic Harlow had memorized in the three hours she’d held Eva at the station, a person of interest in the Veil Market ring. She’d picked Eva out of the British Museum’s restricted archives two nights prior, the only occult researcher in London who’d written three papers on Shade artisans and their compasses, her green eyes sharp even in the dark of the station. You’re looking at a Shade, Eva said. They don’t have five pints of blood. They have half that, and it glows blue, not red. Whoever left this scene tried to stage a human murder, didn’t know that basic fact. Only people with the required bone tokens could access the market’s entrance on Camden High Street. No rival group could’ve gotten in without triggering the ward spells at the door. The only unwarded entry is that maintenance shaft you used to break in. She stepped closer, her own boots avoiding the cracks in the concrete that might hold trace evidence. She nodded at the compass, the needle spinning so fast it looked like a silver blur. That’s his Veil Compass. Only points to the nearest rift. Spinning like that means the killer opened a rift to escape, closed it behind them. They used a rift key, something powerful enough to tear a hole in the veil and seal it before anyone tracked the energy. Rival sellers from the next Veil Market over, probably. They’ve been fighting over territory for months. This Shade was the only artisan in London making working compasses. Whoever killed him cornered the market on the only tool that can find hidden portals. Harlow didn’t look up from the body. She’d run through Eva’s theory a dozen times on the drive over. It fit all the surface details, the same story her team had fed her three years prior, when they’d found Morris’s body in an abandoned warehouse, no blood, a single slash across his throat, a broken ritual knife at his side. They’d told her a supernatural cult killed him, that she’d never find the people responsible. She’d spent three years chasing that lead, digging through Eva’s old papers, tracking every Veil Market pop-up, buying every lead that might point her to the cult that took her partner. She reached out, her nitrile glove brushing the compass’s edge. The spinning didn’t slow. She leaned in closer, her nose almost touching the brass, and saw the thin thread wrapped around the needle’s base, tied to the compass’s inner casing, invisible from more than a foot away. Someone had spun the needle, tied it in place to make it look like it was whirring on its own. She plucked the thread with her nail, and the needle snapped to a stop, pointing dead at the tunnel mouth, at the uniformed officer leaning against the concrete just out of Eva’s line of sight. DC Cole, the first officer who’d arrived at Morris’s crime scene, the first one who’d mentioned the supernatural cult lead. She let her gaze travel back to the sigils etched into the compass’s face. Eva had written in her Oxford master’s thesis that Shade artisans etched sigils from the top right, the old Enochian script that read right to left. The sigils on this brass shell read left to right, backwards, the lines uneven, carved by someone who’d copied a photo off the internet, not a master who’d spent years crafting compasses. This was a fake, planted to look like the Shade had been killed for his work. Her gaze flicked to the floor, ten feet from Cole’s boots. A small black button, the kind sewn onto Met Police uniform blouses, lay half-buried in the mud. She’d seen that button fall off Cole’s jacket that morning, during the team briefing, when he’d ripped his blazer off to grab his vest before the raid. He’d said he’d sew it back on later. She stood, her hand resting on the taser at her hip. The fake blood under the Shade’s body was the same formula the Met used for training simulations, the same stuff she’d seen in the academy’s supply lockers, the same stuff someone on her team could walk in and steal any day of the week. The stab wound was the exact width of the standard issue utility knife all officers carried, the blade sharp enough to slice through wool without fraying the edges. They’d staged the whole scene, carved the wound after they killed the Shade, planted the fake compass, spun the needle to sell the rift story, drained the Shade’s real blood to dispose of it somewhere no one would find, to make it look like a supernatural ritual killing, the same thing they’d done to Morris. Morris had come to Harlow three days before he died, had showed her the files he’d compiled on four officers in their unit, smuggling supernatural goods out of Veil Markets, selling them to private collectors for six figures a pop. The Shade had emailed Morris two weeks prior, had offered to testify against the group, had told them he’d been making compasses for them to find rifts to smuggle goods through, that he couldn’t keep doing it. They’d killed the Shade to silence him, staged the scene to feed Harlow’s obsession with the supernatural cult that killed her partner, to keep her chasing a ghost while they kept running their ring. She pulled her gun from its holster, the sound of the safety clicking off echoing through the tunnel. Cole pushed off the wall, his hand reaching for his own weapon. Stay where you are, Harlow said. Eva froze, her head turning to stare at Cole, then back at Harlow, the pieces of her own theory falling apart as she registered the gun, the button in the mud, the compass that had stopped spinning and pointed straight at the officer in the tunnel. Mills stood, his hands raised, not sure who the threat was. The uniforms at the other end of the tunnel turned, their flashlights all swinging to center on Cole, who’d frozen mid-step, his hand still curled around his holster. You killed Morris, Harlow said. You killed this man, tried to stage it like a supernatural rival hit, thought I’d chase the rift story for another three years, never look at the people standing right in front of me. Cole’s jaw tightened. He made a split-second move to yank his gun free, but three uniforms were on him before he could clear the holster, slamming him into the concrete, his arms wrenched behind his back. The clink of handcuffs echoed off the tile walls, and Harlow holstered her weapon, her gaze drifting back to the Shade’s body, to the fake compass that had almost convinced her another supernatural ghost had slipped through her fingers. For three years, she’d looked for monsters in the veil, in the hidden markets and the shadow rifts, and the monster had been on her team the whole time.
