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.

Harlow Quinn’s boots crunched gravel as she stepped off the curb. The streetlamp beside her flickered, casting a jaundiced glow over the graffiti-draped brick wall. Camden High Street hummed with night owls—students, drunks, a street musician tuning a fiddle—but her car idled silent ten yards down, its radio off. She tapped the bone token—a smooth, irregular shape, carved with a snake swallowing a star—twice against the wall. A section slid inward, revealing a blackness that smelled of damp stone and lemon oil. She adjusted her coat, squared her shoulders, and stepped through. The Tube platform loomed ahead, its concrete cracked and patched with weeds. A single bulb hung from the ceiling, swinging like a metronome. The air thickened—smoke from a half-smoked cigarette, the iron tang of old blood, something else, underlying, sweet as overripe peaches. A uniform cop stood at the far end, his hand on his holster. He didn’t move until she was ten feet from him. “Detective,” he said, voice a mumble. “Thought you said it was bad.” Quinn knelt. The chalk outline was there, but faded, as if drawn days ago. Too precise, though—no smudges, no overspray. The pavement inside it was scuffed, but not from boot heels. Fingertips? Maybe. The area outside was clean. No tire tracks, no footprints. Just silence. “Where’s the body?” she asked. “Gone.” The cop shifted. “Found the outline at dawn. Seventeen hours later, the body was gone. No blood, no nothing. Just the chalk. The medics couldn’t even find a pulse—said the guy was already dead when he hit the ground.” Quinn stood. Her leather watch—worn, its band frayed—read 2:17. She scanned the platform. Graffiti covered the walls: *Beware the Veil*, *Shades collect tears*, *Don’t look back*. The usual. But today, a new tag: a circle, inside it *×*, drawn in a thick, glossy ink that glistened under the bulb. Her eyes flicked to the victim’s satchel, still open. Inside were notebooks—handwritten, the pages filled with equations and sketches of runes— a magnifying glass, a sprig of dried lavender. Beneath them, a flash of brass: the Veil Compass, its casing patinated green. She closed the satchel, careful not to touch the compass. “You recognize this?” Eva Kowalski materialized from the shadows at the platform edge. Her curly red hair poked out from behind round glasses, her freckled nose wrinkled at the smell. “You’re late,” she said. Not a question. She tucked a loose strand behind her left ear, the nervous habit Quinn had known since they were kids. Her satchel—scuffed, leather, stuffed with books—hit her hip as she shifted. “Traffic,” Quinn said. She nodded at the compass. “Shade work.” Eva’s breath hitched. “That’s… that’s a Shade artisan’s work. The patina’s right—verdigris, not rust. The sigils on the face—they’re not for protection. They’re for *warding*.” “Warding what?” “What if the compass wasn’t pointing out? What if it was pointing *in*?” Eva knelt, her satchel thudding. She pressed a finger to the chalk outline. “The victim was here. At night, when the market’s open. Bought something. Or traded.” “Nothing’s traded here without a price,” Quinn said. “Blood, favors, a sliver of your soul. The cop said no body, no blood. That’s not possible here.” Eva flipped open her satchel, pulled out a magnifying glass. “Look at the chalk. See the edges? They’re so sharp, it looks like a stencil. No one *bled* out here. Not from a wound. Maybe… something *sucked* it in.” Quinn studied the chalk. Fine powder, white as bone. No tracks, no stains. The smudge she’d noted earlier—pale, circular, like a coin pressed into wet cement—was still there, near the edge. “What’s that?” “Found it yesterday,” Eva said. “Thought it was a cigarette butt. Smelled like mint. Looked like ash, but… not.” She took a small plastic bag from her satchel, tucked the smudge inside. “Lab’ll tell us what it is. If it’s not… y’know.” “Not human,” Quinn finished. She picked up the compass, turned it over. The sigils glowed faintly, under her thumb. “Morris would’ve loved this. He used to collect oddities. Said they were ‘clues with teeth’.” Eva’s face tightened. “He’s dead, Harlow.” “I know.” Quinn set the compass down, hard, on the pavement. The smudge shifted. “That’s the problem. The evidence doesn’t add up. No body, no blood, no tracks. Why would someone leave a chalk outline? Why a compass?” Eva stood, her satchel slung over her shoulder. “Maybe the victim *wanted* to be found. They put the compass there. Left the smudge. Lured someone here.” Quinn shook her head. “Who lures someone to a hidden market with a stolen compass? And why leave the chalk? Taunt the cops?” “Maybe the chalk’s a warning,” Eva said. “‘I was here.’ ‘Beware.’ Shades leave marks like that. Testing the waters.” The bulb popped. Dark flooded the platform. In the silence, the sigils on the chalk outline glowed, faint but bright, like embers. Quinn fumbled for her phone, its screen casting a blue light. The flashlight illuminated the smudge—now a fine, iridescent powder, sparking like crushed diamonds. “Eva,” she said, “remember what Morris wrote about the rift? The one he couldn’t close? He said it felt like hunger. Like something *wanted* to get through.” Eva’s voice was quiet. “I read the reports. They’re classified. You shouldn’t—” “Classified doesn’t mean it’s not real.” Quinn knelt, the compass in her hand. It vibrated, the needle spinning wildly. “The compass is pointing here. To the rift. The victim was looking for it. Or *to* it.” “Stop,” Eva said. “You don’t know—” “I know the market trades in voids,” Quinn said. “Keys. Portals. People pay to open them, to see what’s on the other side. But what if the Shades aren’t just *selling* rifts? What if they’re *waiting* for someone to open one?” The compass stilled. The sigils on its face dimmed. Quinn stood, the compass in her palm. “The chalk. It’s a seal. Or a *trap*. They drew the outline to keep the rift closed—until the victim came. Then they… let it out.” Eva’s hand went to her satchel. “I’ve seen Shade rituals. Their sigils are old. From before the Veil. They don’t like outsiders meddling. Especially not with rifts.” Quinn stepped out of the outline. The compass hummed. “Tell the lab to check the chalk. Find out what it’s made of. And dig up that smudge. It’s not a coin. It’s a *trigger*.” Eva nodded, her freckles clustered tight. “Harlow… be careful. Whatever this is, it’s not human.” Quinn looked at her, sharp jaw set, eyes sharp as a scalpel. “Neither was Morris.” She walked toward the wall, the compass still in her hand. The section slid open, moonlight pouring in. But the market’s noise—barkers, haggling, laughter—wasn’t there. Just silence. She stepped through, the door sliding shut behind her. Below, in the bowels of the market, the chalk outline glowed. And somewhere, far off, a clock ticked. --- The scene ends as per the mystery’s progression, with the compass guiding Quinn and the mystery of the rift lingering—no conclusion, just a continuation of the investigation.
