You are an expert and award-winning novel writer in the dark Thriller genre. Your readers are hooked on your stories and can't wait to read the book you have in store. <important> - MUST: Start each chapter in medias res (in the middle of action). AVOID talking about the weather, time of day, the position of the sun, or other boring stuff. - The instructions/summary are just a that, a summary. Feel free to add details, stretch sections and add interesting transitions/descriptions/fillers. - When called for it, have fast-paced action, but otherwise take things slow. This is an experience, and not for people with short attention spans. Enjoy the wine, not slurp Red Bull. - Add descriptions when transitioning places/times/etc, or when coming by new places (e.g. a corner shop, a cafe, etc.). But remember: NOT at the start or end of a chapter. - MUST: AVOID ending in internal monologue, reminiscing or waiting for the next day. A good chapter end is when we're ending right when shit hits the fan. We want to have the reader be excited for what comes next. So no reminiscing, contemplating or summarizing the day. It's popcorn time! </important>

It was time to go to the store.</good> - Avoid redundant adverbs that state the obvious meaning already contained in the verb: - <bad>She whispered quietly to her mom.</bad> - <good>She whispered to her mom.</good> - Use stronger, more descriptive verbs over weak ones: - <bad>Daniel drove quickly to his mother's house.</bad> - <good>Daniel raced to his mother's house.</good> - Omit adverbs that don't add solid meaning like "extremely", "definitely", "truly", "very", "really": - <bad>The movie was extremely boring.</bad> - <good>The movie was dull.</good> - Use adverbs to replace clunky phrasing when they increase clarity: - <bad>He threw the bags into the corner in a rough manner.</bad> - <good>He threw the bags into the corner roughly.</good> - Avoid making simple thoughts needlessly complex: - <bad>After I woke up in the morning the other day, I went downstairs, turned on the stove, and made myself a very good omelet.</bad> - <good>I cooked a delicious omelet for breakfast yesterday morning.</good> - Never backload sentences by putting the main idea at the end: - <bad>I decided not to wear too many layers because it's really hot outside.</bad> - <good>It's sweltering outside today, so I dressed light.</good> - Omit nonessential details that don't contribute to the core meaning: - <bad>It doesn't matter what kind of coffee I buy, where it's from, or if it's organic or not—I need to have cream because I really don't like how the bitterness makes me feel.</bad> - <good>I add cream to my coffee because the bitter taste makes me feel unwell.</good> - Always follow the "show, don't tell" principle. For instance: - Telling: <bad>Michael was terribly afraid of the dark.</bad> - Showing: <good>Michael tensed as his mother switched off the light and left the room.</good>- Telling: <bad>I walked through the forest. It was already Fall, and I was getting cold.</bad> - Showing: <good>Dry orange leaves crunched under my feet. I pulled my coat's collar up and rubbed my hands together.</good>- Add sensory details (sight, smell, taste, sound, touch) to support the "showing" (but keep an active voice) - <bad>The room was filled with the scent of copper.</bad> - <good>Copper stung my nostrils. Blood. Recent.</good> - Use descriptive language more sporadically. While vivid descriptions are engaging, human writers often use them in bursts rather than consistently throughout a piece. When adding them, make them count! Like when we transition from one location to the next, or someone is reminiscing their past, or explaining a concept/their dream... - Avoid adverbs and clichés and overused/commonly used phrases. Aim for fresh and original descriptions. - Avoid writing all sentences in the typical subject, verb, object structure. Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. Like so: <good>Locked. Seems like someone doesn't want his secrets exposed. I can work with that.</good> - Convey events and story through dialogue. It is important to keep a unique voice for every character and make it consistent. - Write dialogue that reveals characters' personalities, motivations, emotions, and attitudes in an interesting and compelling manner - Leave dialogue unattributed. If needed, only use "he/she said" dialogue tags and convey people's actions or face expressions through their speech. Dialogue always is standalone, never part of a paragraph. Like so: - <bad>"I don't know," Helena said nonchalantly, shrugging her shoulders</bad> - <good>"No idea" "Why not? It was your responsibility"</good> - Avoid boring and mushy dialog and descriptions, have dialogue always continue the action, never stall or include unnecessary fluff. Vary the descriptions to not repeat yourself. Avoid conversations that are just "Let's go" "yes, let's" or "Are you ready?" "Yes I'm ready". Those are not interesting. Think hard about every situtation and word of text before writing dialogue. If it doesn't serve a purpose and it's just people talking about their day, leave it. No one wants to have a normal dinner scene, something needs to happen for it to be in the story. Words are expensive to print, so make sure they count! - Put dialogue on its own paragraph to separate scene and action. - Use body language to reveal hidden feelings and implied accusations- Imply feelings and thoughts, never state them directly - NEVER use indicators of uncertainty like "trying" or "maybe" - NEVER use em-dashes, use commas for asides instead </styleGuide> <voiceGuide> Each character in the story needs to have distinct speech patterns: - Word choice preferences - Sentence length tendencies - Cultural/educational influences - Verbal tics and catchphrases Learn how each person talks and continue in their style, and use their Codex entries as reference. <examples> - <bad>"We need to go now." "Yes, we should leave." "I agree."</bad> <good>"Time's up." "Indeed, our departure is rather overdue." "Whatever, let's bounce."</good> - Power Dynamic Example: <bad> "We need to discuss the contract." "Yes, let's talk about it." "I have concerns." </bad> <good> "A word about the contract." "Of course, Mr. Blackwood. Whatever you need." "The terms seem..." A manicured nail tapped the desk. "Inadequate." "I can explain every-" "Can you?" </good> </examples> </voiceGuide> <dialogueFlow> When writing dialogue, consider that it usually has a goal in mind, which gives it a certain flow. Make dialogue sections also quite snappy in the back and forth, and don't spread the lines out as much. It's good to have details before, after, or as a chunk in-between, but we don't want to have a trail of "dialogue breadcrumbs" spread throughout a conversation. <examples> - Pattern 1 - Question/Deflection/Revelation: <good> "Where were you last night?" "Work. The usual." "Lipstick's an interesting shade for spreadsheets." </good> - Pattern 2 - Statement/Contradiction/Escalation: <good> "Your brother's clean." "Tommy doesn't touch drugs." "I'm holding his tox screen." </good> - Pattern 3 - Observation/Denial/Truth: <good> "That's a new watch." "Birthday gift." "We both know what birthdays mean in this business." </good> - Example - A Simple Coffee Order: <bad> "I'll have a coffee." "What size?" "Large, please." </bad> <good> "Black coffee.""Size?""Large. Been a long night." "That bodega shooting?" "You watch too much news." "My brother owns that store." </good> This short exchange: - Advances plot (reveals connection to crime) - Shows character (cop working late) - Creates tension (unexpected connection) - Sets up future conflict (personal stake) - Example - Dinner Scene: <bad> "Pass the salt." "Here you go." "Thanks." </bad> <good> "Salt?" "Perfect as is. Mother's recipe." "Mother always did prefer... bland things." "Unlike your first wife?" </good> - Example - Office Small Talk: <bad> "Nice weather today." "Yes, very nice." "Good for golf." </bad> <good> "Perfect golf weather." "Shame about your membership." "Temporary suspension. Board meets next week." "I know. I called the vote." </good> </examples> </dialogueFlow> <subtextGuide> - Layer dialogue with hidden meaning: <bad>"I hate you!" she yelled angrily.</bad> <good>"I made your favorite dinner." The burnt pot sat accusingly on the stove.</good> - Create tension through indirect communication: <bad>"Are you cheating on me?"</bad> <good>"Late meeting again?" The lipstick stain on his collar caught the light.</good> <examples> - Example 1 - Unspoken Betrayal: <bad> "Did you tell them about our plans?" "No, I would never betray you." "I don't believe you." </bad> <good> "Funny. Johnson mentioned our expansion plans today." "The market's full of rumors." "Mentioned the exact numbers, actually." The pen in his hand snapped. </good> - Example 2 - Failed Marriage: <bad> "You're never home anymore." "I have to work late." "I miss you." </bad> <good> "Your dinner's in the microwave. Again." "Meetings ran long." "They always do." She folded the same shirt for the third time. </good> - Example 3 - Power Struggle: <bad> "You can't fire me." "I'm the boss." "I'll fight this." </bad> <good> "That's my father's nameplate you're sitting behind." "Was." "The board meeting's on Thursday." </good> </examples> </subtextGuide> <sceneDetail> While writing dialogue makes things more fun, sometimes we need to add detail to not have it be a full on theatre piece. <examples> - Example A (Power Dynamic Scene) <good> "Where's my money?" The ledger snapped shut. "I need more time." "Interesting." He pulled out a familiar gold pocket watch. My mother's. "Time is exactly what you bargained with last month." "That was different-" "Was it?" The watch dangled between us. "Four generations of O'Reillys have wound this every night. Your mother. Your grandmother. Your great-grandmother.Shall we see who winds it next?" </good> - Example B (Action Chase) It's much better to be in the head of the character experiencing it, showing a bit of their though-process, mannerisms and personality: <good> Three rules for surviving a goblin chase in Covent Garden: Don't run straight. Don't look back. Don't let them herd you underground. I broke the first rule at Drury Lane. Rookie mistake. The fruit cart I dodged sailed into the wall behind me. Glass shattered. Someone screamed about insurance. *Tourist season's getting rough*, the scream seemed to say. Londoners adapt fast. "Oi! Market's closed!" The goblin's accent was pure East End. They're evolving. Learning. I spotted the Warren Street tube station sign ahead. *Shit.* There went rule three. </good> - Example C (Crime Scene Investigation) <good> "Greek." Davies snapped photos of the symbols. "No, wait. Reverse Greek." "Someone's been watching too many horror films." I picked up a receipt from the floor. Occult supply shop in Camden. Paid by credit card. *Amateur hour*. "Could be dangerous though," Davies said. "Remember Bristol?" "Bristol was Sanskrit. And actual cultists." I pointed to the nearest symbol. "This genius wrote 'darkness' backwards but used a Sigma instead of an S. It's summoning Instagram followers at best." "Speaking of followers..." Davies pointed to heavy foot traffic in the dust. Multiple sets. All new trainers. *Ah.* "Anyone check local uni paranormal societies?" </good> - Example D (Dialogue-heavy) <good> "Found your card in her wallet." The detective slid it across the table. Worn edges. Folded corner. Three years old at least. "Standard practice. I work missing persons." "Funny thing about missing persons.Eventually they stop being missing. Turn up in the Thames. Under motorways. In pieces." "I don't-" "You found four last year. All breathing." She opened a file. "This would've been your first dead one. If we hadn't found her first." The card felt heavier somehow. </good> </examples> </sceneDetail> <sceneOpenings> KEY RULE: Never open with more than one paragraph of description, no matter how beautiful. Description should be earned through action and dialogue. Instead of opening with setting description, open with: - A character doing something specific - A line of dialogue that raises questions - An unexpected observation - A moment of tension or conflict - Start with a hook that's 1-2 sentences maximum - Follow with a smaller paragraph that provides immediate context - Vary paragraph size from the start to create visual interest </sceneOpenings> </proseGuidelines> Write a chapter based on the following instructions: <instructions> Write a fully fleshed out scene of at least 1000 words in the thriller genre. A detective is pursuing a suspect through rain-soaked city streets at night. The chase takes them from the street level down into an underground market. The detective must decide whether to follow the suspect into unfamiliar and potentially dangerous territory. Use the codex entries above as your world reference for characters and setting. Only include the prose of the scene without any markdown or commentary. </instructions>

"Police! Stop!" Quinn drove her shoulder into the swinging pub door and burst back onto the street, boots punching arcs of dirty water up from the pavement. The hooded figure was already halfway across the road, clearing the bonnet of a black cab in one smooth slide that left a smear of wet on the windscreen. Horn. Swear. Tyres. She ignored all of it and ran. Traffic tore past in both directions. He threaded straight through gaps that did not exist, a dark cut in the glare of headlights and brake lights. Quinn picked the worst opening and took it, one palm flat on the side of a van as it skidded to a stop inches from her hip. "Jesus Christ, watch it!" She kept going. Her lungs burned, cold air sawing in and out, the familiar rhythm of a chase settling into her muscles. Eighteen years of running other people down. You learned what a body could do. You learned when someone moved like they had something to lose. Up ahead, the suspect swung left, vanishing down a side street thick with people spilling from bars and takeaways. No chance to radio properly. She slapped the button on her shoulder mic as she ran. "Control, this is DI Quinn, in foot pursuit, male, dark hoodie, Camden High Street, heading east, he is linked to the Soho stabbing, inform any units nearby." Static crackled in her ear, then a snatch of a reply she lost as she shoved through a knot of tourists. "Oi, watch where you're going!" Warm vinegar and fried food hit her nose, hot grease slick under her soles. He barged a couple away from the edge of the pavement; one of them dropped a cone of chips that exploded under his heel. He never broke stride. He did not check his backtrail. He ran like someone who knew his route and trusted it. Too clean. Too fast. "Move!" Quinn snapped, as a group with umbrellas fanned out in her path, more shield than shelter. She dipped her shoulder, went low, forced a gap between two dripping coats and came out into open street again. She caught sight of his profile for a heartbeat. Pale jaw, a scatter of dark stubble, mouth tight. Not a kid. Late twenties, maybe early thirties. The streetlight cut a brief line along the side of his face. Scar at his temple. She filed it away. He vaulted a railing, feet slamming down on stone steps that dropped steeply between two graffiti-stained walls. He took them three at a time. Quinn hit the top a moment later and felt her stomach drop with the angle of descent. Old Tube entrance. The iron gate at street level hung twisted on one hinge, chain sheared clean. The actual station signs up top had long gone, but the memory of them stayed in the shape of the brickwork, the curve of the arch. Someone had stencilled a new name under the old ghost outline. NO ENTRY. Below, darkness swallowed him. A smear of motion, then nothing. She paused at the lip of the stairs, took one hard breath, shook the water from her eyes and went down. The sound of the street deadened with each step. Traffic became a muffled growl overhead. The air cooled and thickened, heavy with damp stone and old oil, the ghost of electricity from cables that no longer hummed. Her soles slapped the wet concrete, echo slapping back. "Control, lost visual, entering disused station, sending location." Nothing in her ear now. Just a hiss like breath across the mic. She unclipped it, checked the cord, swore under her breath and clipped it back. Brick funneled the sound of her own steps back at her, doubled. It made the back of her neck itch. She adjusted the leather strap of her watch where it had stuck to her skin and drew her torch with one hand, her other resting on the butt of her Glock. The stairwell opened into a short corridor of old cream tiles, most of them cracked or missing. Somebody had tagged over them. Not usual gang spray. Lines and loops that looked like writing until you tried to read them. They refused to settle into sense, twisting in her eye like they did not want to be looked at directly. He had gone this way. Wet prints marked in black the faded red of the floor, each one already softening at the edges. Quinn moved faster. The corridor kinked once, then spat her into a wider space. The old ticket hall, long stripped of glass and machines. Empty would have made sense. Dust, maybe a couple of sleeping bags. Kids. Taggers. Not a heavy red curtain strung across the far wall like a makeshift stage, gathered around the edge of a tiled archway. Not two men in long coats flanking it like door supervisors in some underground club, shoulders filling most of the space. The suspect was in front of them, hood back now. Dark hair, close-cropped, soaked flat to his skull. A plastic carrier bag swung from one hand, the cheap white turned grey by water and dirt. He held out his other hand to one of the men, palm up. A small round object lay there. The thing caught the light of the single working strip overhead, the colour of old ivory, etched with lines. Bone. Quinn flattened herself against the nearest support pillar, breath steadying to something slower and sharper. She peered round. The big man took the disc, weighed it once in his palm, then grinned. His teeth looked too even, too white in the poor light. "Welcome back, Nico." He passed the disc back. The curtain twitched, not from any visible hand, like something on the other side had drawn it aside. A spill of light leaked out, not one colour but many, sun-bright, neon-sour, all at once. Noise rode the light. Voices, a steady low roar. Metal. Laughter. A sound like an animal complaining. The smell hit her next. Spices she could not name, cinnamon and smoke, rot and bleach, burned sugar, wet fur. Nico ducked through the gap with the kind of casual familiarity that turned Quinn's stomach. He had not discovered this place tonight. He belonged here. The curtain fell back. The light and sound dulled, pressed away, but did not vanish. It hummed in the air, just behind the brick. The big man on the left shifted his weight and the light caught his face properly for the first time. He was thick-necked, with coarse black hair tied at the nape. His skin had that hard shine you saw on old fighters. One blue tattoo spiral climbed from his collar up the side of his jaw. It twisted around his ear and disappeared into the hairline. His eyes, when he scanned the empty hall, moved too smoothly. The pupils were pinpoints in a ring of pale grey. Quinn slid back behind the pillar as his gaze swept in her direction. Her fingers closed round the grip of her gun. Urban legends, that was all. Old coppers at late bars talked about a market that moved around the city, only opened for people with the right kind of invitation. A place you could buy anything. No addresses, no photos, just stories. The sort of rubbish they had joked about after Morris died. Her chest tightened once, hard, at the memory of his funeral suit hanging slack on the wardrobe door. She refused the picture and looked back at the curtain. She had him. Nico. The little knife at the Raven's Nest, the body in the alley by Greek Street with their throat opened like a second mouth. Witnesses had put him near. CCTV had caught a sliver of that same profile, that same scar on the temple, the shadow of a carrier bag. Tonight he had walked straight past her at the bar, left without a hurry. And now this. An entrance to nowhere, hidden in a forgotten station under Camden. Quinn eased her gun from its holster. Safety on. Her other hand flicked her torch off and clipped it back. Light would do her no favours now. Move. Do not think. She stepped out from cover. The two men straightened as one, the way dogs did when they scented something off. "You are not supposed to be down here," the one with the spiral tattoo said. His voice sounded like stone dragged on stone, slow, strangely careful with each syllable. Quinn lifted her warrant card in one hand, gun low in the other, pointed at the ground but where she could bring it up in a blink. "Detective Inspector Quinn, Metropolitan Police. The man who just went in is a suspect in a murder investigation. Step aside." The one on the right laughed, a short dry bark. He was narrower than the first, tall and almost lanky, his coat sitting wrong on him, shoulders too high. No cabin crew posture, more like something unsure how to arrange itself into human shape. "Badges," he said. "Everyone loves badges. Got a badge, you think it makes the rules yours." "The rules here are different," the tattooed one said. "Different how?" Quinn said. "Entry by token only." He tapped the chain round his neck with one heavy finger. A line of pale discs hung there, each one no bigger than a two-pound coin. Bone. All of them. Quinn met his gaze and did what she always did when someone tried to move the ground under her. She ignored it. "You block me and you obstruct a murder investigation. That is prison time. Move." The narrow one tilted his head, bird-curious. "Prison time," he repeated, like he tasted the phrase. "For us." "You heard her," the tattooed one said. "She thinks bars can hold us." Three beats of silence. The drip of water somewhere in the dark behind her. The muffled thud of bass far above, from a world that had no idea what sat under its feet. Quinn decided. She took a step closer, just into their space, and pitched her voice flat. "You let me through or I arrest you both. Or I put you down. Choice is yours." His lips peeled back. Not a smile. The narrow one flicked his coat open. His hand blurred, too fast for a man that size. Quinn did not wait to see what he reached for. She moved. Her gun came up, barrel tracking centre mass. Her boot went in low, heel to ankle. Not fancy, just solid. The narrow man's leg buckled, his weight crashing sideways into the tattooed one. Whatever he had reached for, it clattered to the floor. Quinn surged into the opening, one shoulder ducked, driving a forearm into the narrow man's throat to pin him to the curtain. The fabric was thicker than it looked, rough under her fingers, hot from the heat bleeding through from the other side. Something shifted against her back from beyond the curtain, like a crowd pressed in. The tattooed one snarled. It did not sound like a man at all. His hand clamped on her arm, fingers almost meeting round her bicep. Pain flared sharp and hot. His grip felt wrong, the tendons under his skin thick as wire. She twisted, drove the muzzle of her gun into the meat of his wrist and squeezed. The shot turned the small hall into a grenade of sound. Her ears rang, white noise screaming. The smell of burned cordite cut sharply through damp air. He yelped and his hand jerked back, a spray of something dark flicking across the tiles. He moved with it though, not away. He came in low, shoulder first, using sheer weight to slam her back. The curtain took some of the impact, swaying, but the frame behind it stayed solid. Her skull bounced and for a heartbeat the world flickered out at the edges. Get lower. Centre. Move. She stamped on his instep as hard as she could. Felt crunch. He grunted and faltered. The narrow one recovered faster than he should have. His fingers clawed at her sleeve, cold and dry. She tore free, using her momentum to roll sideways. Her boot hit something small and hard. It skittered across the floor and rang off the base of a long-lost ticket kiosk. A bone disc. The tattooed one lunged again, other arm sweeping for her throat. She went under his arm, came up on the other side of them, heart punching against her ribs. For a moment, both men had their backs to the curtain, their balance off. That was all. Quinn dived for the disc. Cold bit her fingertips as she closed her hand round it. Not cold like ice, cold like something taken from a deep drain. Tiny grooves scored its surface, worn by a hundred thumbs. It felt heavier than it had any right to. The tattooed man shouted. "Drop it." She ignored him. The narrow one came at her, hand outstretched. His nails had lengthened, she noticed that in some detached part of her mind, curved and pale like little horns. Quinn snapped the disc up and slammed it against the metal plate bolted to the wall beside the curtain. The plate had looked like nothing before. Dead steel, dark with age. Now the lines carved into it flared to life, sudden and fierce, white-blue, racing out in a web of light. The air shuddered. Sound bent, folding in on itself. Pressure clamped around her skull, her teeth. The world tasted of iron and ozone. Her hair prickled along her scalp. The men flinched back. The narrow one hissed, a high animal noise, eyes squeezed shut. The tattooed one reached for her, fingers grasping, but the curtain snapped open, snatched back by hands she could not see. Light hit her. It drowned the hall in colour and motion. Stalls jammed shoulder to shoulder in a space that could not exist under London. Lanterns and bare bulbs and things that were not any kind of light she recognised hung from cables and bone and chains. Hundreds of bodies moved between them, none of them right. Too tall, too short, too many limbs, wrong joints. Human faces, animal faces, faces that were something else entirely, all turning as one towards the sudden opening. Noise washed over her like a wave. Bells. Laughter. Haggling in a dozen tongues. The sizzle of meat on metal. A child crying. Somewhere, something roared. And in the gap that the crowd made, straight down the main passage of the impossible market, Nico stood on a crate, carrier bag gone, a long thin metal case in his hand. His head snapped up at the sound of the shot, or the flare of light, or the taste of her in the air. He saw her. His eyes widened. He reached into the case. Quinn stepped through the threshold into the Veil Market, gun raised at him, as the narrow doorman launched at her back with a snarl and something like a blade of black glass ignited in Nico's fist.
