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>

Harlow Quinn grabbed the suspect by the sleeve and felt the fabric fight back like it had a memory of slipping free. “Stop,” she said. He didn’t even turn. He wove through the foot traffic as if everyone else had agreed not to see him. Rain slicked the pavement into a mirror, turning streetlights into smeared coins. Harlow kept her grip, fingers digging where the cuff seam met the knuckle, and yanked. The man stumbled. Then he smiled, small and mean, like she’d picked the wrong door. “You’re late, Detective.” Harlow’s other hand went to her belt, came up with her torch, and swung the beam into his face. Brown eyes. Warm skin. Too calm. The kind of calm that belonged to someone who’d already rehearsed this moment. His name wasn’t in her head. It should have been, not after the photo, not after the call, not after the string of bodies the clique had kept close enough to touch. Still, she couldn’t shake the wrongness, the shape of the case turning in her gut like a lock that wouldn’t open. He pulled free with a twist that didn’t match the strength in his arms. Something glittered at his wrist, bone-white under the rain. Not jewellery. A token. Harlow’s stomach tightened. Bone tokens meant one thing. The Veil Market. He took one step back and the air in front of him shivered, like heat off tar, like glass vibrating. A seam of darkness opened between two parked vans, narrow as a knife cut. The suspect slipped his shoulder through it. The rain hitting the surrounding air sounded thicker, muffled, as if the world didn’t want to be involved. Harlow had seconds, not minutes. Her training screamed at her to secure the suspect, call for backup, keep it clean. Her experience of the impossible screamed something else. Don’t chase into gaps you don’t understand. She lunged anyway. Cold hit first, a damp that sank past her coat and into her bones. The smell followed, metallic and sweet, like old coins warmed in a fist. The city noise dropped away, replaced by a low hum, distant chanting or machinery, too layered to pin down. Harlow’s torch beam sliced forward, showing a stairwell that hadn’t existed a moment ago. She hit the steps hard, one hand on the railing, the other still searching for the suspect’s sleeve. Rainwater dripped from her hair into her eyes. She blinked it away and found him five steps ahead, moving fast but not running. He knew this place. The stairwell widened as they went down. The walls gained brick, then stone, then something that looked like it had grown rather than been built. Charcoal stains crawled along the curve, and the torchlight caught symbols etched at shoulder height, shallow scratches that didn’t show under the beam until she moved, like they fed on perspective. Harlow followed the suspect into a corridor lit by green-blue bulbs, each one flickering like an eyelid over a bruise. The smell thickened. Oil. Spices. Damp paper. An undertone of bleach that promised cleanliness and delivered poison. The suspect glanced over his shoulder, just once. “You want answers, don’t you? You’ve been hunting the wrong man.” “You don’t get to tell me what I want,” Harlow said. Her voice sounded too loud in this place, too normal, like a siren you didn’t belong to. He laughed quietly, then pointed down the corridor. “Then don’t come if you’re scared.” “I’ve lost partners,” she said, and the words came out sharper than she intended. Her worn leather watch on her left wrist clicked as her arm moved. “I don’t scare easy.” His expression changed at that. Not fear. Recognition. The corridor ended in a wide platform beneath what used to be an abandoned Tube line. Harlow found herself in a station swallowed by commerce. Stalls lined both sides, their canopies hung with cords that pulsed faintly, as if something inside them kept beating. Goods sat in glass cases and open crates, not arranged with any human notion of neatness. A row of candles burned without flames, dripping coloured wax that didn’t melt. Dried herbs hung like prayers. Bottles of pale liquid glowed from within, each stopper sealed with wax stamped in unfamiliar scripts. At the far end, a crowd moved with purpose. Not panicked. Not random. Buyers and sellers flowed around each other like blood cells, all direction and no collisions. Harlow swallowed. This wasn’t a market anymore. It was a vein. The suspect didn’t slow. He threaded through two clusters of shoppers and vanished behind a partition made from stacked train seats, their faded upholstery worn down to threads. Harlow pushed through after him. Her torchbeam skimmed signs made of hammered metal. Some names looked like English until the letters rearranged themselves under her gaze. One read VEIL MARKET in capital strokes, then the N bled into a symbol like a closed eye. A voice to her left spoke above the hum. “Bone token. You see a gate, you go.” Harlow turned. A vendor leaned on a counter, wearing a coat too thin for the cold. Their face had the smoothness of someone who rarely let the world touch it. A collection of keys jingled at their belt, each key a different shape, each one stained by something dark. Harlow held her torch steady. “I don’t need lessons.” The vendor’s gaze slid past her, to where the suspect had disappeared. “You follow, you learn. You stay, you pay.” “I’m not buying,” Harlow said. “Oh, but you are,” the vendor replied. Their smile never reached the eyes. “You’re already in.” Harlow took a step after the suspect, and the floor changed under her boot. Not physically. Logically. The corridor ahead seemed to stretch, the distance between her and the train-seat partition stretching too far for the space it occupied. Her torchbeam stuttered, and the wall on the left rippled, showing layers of paint beneath, different colours, different ages, as if the station had worn disguises and swapped them out. She hated it. She didn’t get to hate it. She needed the suspect. She broke left, cutting through a gap between stalls. A hanging chain of tiny bells brushed her coat as she passed, and each bell chimed with a note that felt wrong in her skull, like the sound triggered a reflex she didn’t possess. “Detective Quinn,” someone said behind her, and the name landed like a hand on her throat. Harlow’s shoulders tightened. She pivoted fast enough her torchlight whipped across faces. Silence didn’t happen. The station didn’t pause. People just stopped paying attention. Their heads turned with the unhurried coordination of an audience. Then she saw him. The man from the stairwell stood three metres away, hands open, as if he had never run at all. His bone token hung from a string at his belt now, white against his dark coat. He looked less like a suspect and more like a lecturer. Harlow’s jawline felt like it might crack under the pressure she pushed into it. “How do you know my name?” He nodded toward the vendor behind her. “Information sells better than steel.” Harlow’s torchlight caught the edge of something on his throat. A medallion, or the shape of one. Not Saint Christopher, hers had seen too many cases where symbols got copied and repurposed. This one looked similar in silhouette, but it wasn’t the same. Another wrongness. “You’re not alone,” Harlow said. She scanned, counting bodies, noting how none of them actually moved closer to intervene. They were spaced like tripwires, waiting for her to step into their planned geometry. He tilted his head. “Neither are you.” Her watch clicked again. She hadn’t realised she’d been gripping it. Harlow took a slow step forward, enough to test the ground and test the air. The station hummed back, and for a second she tasted copper on her tongue. Then she felt it, the pull, subtle as a hook under the skin, drawing her toward a door she hadn’t seen before. A booth sat half-hidden between an armour stand and a rack of crooked umbrellas. A curtain of black fabric hung from a rail. The fabric moved though there was no draft. Letters stitched into the cloth shifted colour, from grey to green, then to something like bruised purple. The token around the suspect’s belt twitched. He watched her watch. “You want him,” he said. “Follow the right way.” Harlow’s gaze didn’t leave the curtain. “You were running.” “I was guiding,” he corrected. “There’s a difference.” “There’s no difference,” Harlow said. “In this city, people run because they’re afraid, and they guide because they’re leading you into a trap.” He grinned at that, teeth bright under the dim bulbs. “Then it’s a good thing I’m not afraid of you.” Harlow shifted her stance, placing her body between the suspect and the curtain. She kept her torch angled low. The beam would reach his shoes first, if he moved. He lifted one hand slowly, as if he respected her, as if this was a dance and not a hunt. At his fingertips, something pale appeared, bone-white and thin as fingernails. He flicked it once. It snapped through the air with a dry crack. A shopper screamed. A woman stumbled backward, clutching her wrist as if it had been cut without blood. Her eyes rolled. A thin line of frost traced from her palm to her elbow. The frost didn’t freeze her skin, it calcified it, turning the surface to brittle chalk. She collapsed in a heap among baskets of enchanted spices. Harlow’s blood surged into her ears. She didn’t move fast enough to stop it. The suspect lowered his hand. “See? I don’t need you to chase. I just need you to choose.” Harlow’s torch beam snapped up toward his face. “You’re hurting people.” He shrugged, light as rain on glass. “They came to a market under a city. They trade things they shouldn’t. That’s the rule. You know it. You just pretend your badge makes you exempt.” Something in him hit the nerve of her partner’s death. Not the supernatural origin she still couldn’t name, but the way the case had turned on consent. On permission. Harlow’s voice went colder. “Where is the rest of your lot?” He leaned in slightly. “Which part? The part that cleans up, or the part that sells?” “Both,” Harlow said. He smiled wider. “Then you follow me.” The curtain rippled again. A narrow opening appeared, like a mouth parting. Harlow felt the air from inside pour out, and it carried a scent she recognised from another place, another night, another kind of wrong. Fried metal. Oiled leather. Alcohol. A bar smell, dim and intimate, the kind that came with secrets. The Raven’s Nest. She hadn’t expected this market to connect to it. She hadn’t expected a suspect to direct her down a route that led back to the clique’s throat. Harlow’s mind flashed with two paths: stay on the station floor, call for backup, try to secure evidence under conditions she understood, or step through the curtain and risk losing herself in a place that moved on tokens and rules she didn’t make. She could hear her own pulse. She hated the question. Then the station lights flickered, green-blue turning to a deeper shade like bruising. The hum rose in pitch. The crowd around them shifted, tightening the ring. People who had been strangers now felt like an organised wall. Harlow moved first. She yanked her torch closer and shoved it toward the curtain’s opening, aiming the beam into the darkness. Light flared inside like breath on glass. For a heartbeat, she saw the back of shelves, map-covered walls, black-and-white photographs. Then something snapped the beam sideways, as if unseen hands pushed it away. The curtain swallowed the light. The suspect’s grin sharpened. “Now you know.” Harlow stepped forward anyway, boots scraping on a floor that resisted her weight with faint suction. Her left wrist watch felt suddenly heavy. She kept her grip on her torch. She didn’t let her hand lower, didn’t let her body soften. The curtain parted for her, or forced itself around her, and the world became narrower, compressed. Sound changed, thickened. The hum faded. Rain smell vanished. Instead, she caught smoke and old wood. The inside of the curtain opened into a dim corridor that led to— A bookshelf. Just as she’d heard. A hidden passage, accessible through a bookshelf. The suspect walked ahead of her into a small room. The shelves stood on one side like a false wall. Leather spines and brittle paper sat behind glass, titles she couldn’t read. A green neon glow leaked from somewhere behind the maps. Harlow entered and shut her eyes for one second, forced her senses to reset. She didn’t want to stumble into a trap blind. When she opened them, the suspect had stopped at the centre of the room, one hand raised like he wanted to show her something sacred. “Three years ago,” he said, voice calm enough to make her skin prickle, “you watched a man die under lights you couldn’t name.” Harlow’s throat tightened. “You’re not DS Morris.” “I’m not,” he agreed. “But you still look for him in every darkness.” Harlow gripped her torch until the plastic creaked. “Who are you?” The suspect’s eyes flicked to the shelves. “You should ask who owns the keys.” The hum returned, faintly, from beyond the corridor, as if the market remembered her presence. Harlow turned her head just enough to check the entrance. The curtain behind her was closed. Not with fabric. With solid darkness. The shelves trembled, and the bookshelf shifted a fraction of an inch, like something inside adjusted its grip on the room. The suspect didn’t flinch. He watched her, satisfied. Harlow understood then, not as thought but as instinct, that she hadn’t been invited into a conversation. She’d been locked into a mechanism. She lifted her torch, aimed at the spines, hunting for a symbol that would explain the trigger. Her beam caught a map stuck to the wall behind the bookshelf, old ink scabbed over with new labels. London’s street grid, marked with lines and circles. Soho, Camden, tunnels. Connections. Her eyes landed on a circle labelled QUINN. Then a second circle pulsed, faintly, with the same bone-white glow as the token at the suspect’s belt. Harlow didn’t breathe. The suspect stepped back into the shadow near the photographs, his outline breaking apart at the edges, like the room couldn’t decide where he belonged. “Detective Quinn,” he said again, and her name sounded like a key trying doors. Harlow’s torchlight shook. She felt the room tighten around her. The bookshelf eased forward, preparing to swing. Somewhere outside, something clicked, metal on metal, the sound of a lock finding its final teeth. Harlow took one step toward the shelves, fast enough to make the floor shiver, and thrust her torch at the seam where the bookshelf met the wall. The light hit— Bone. A thin blade of it, hidden in the join, slick with rainwater that shouldn’t have existed here. It glimmered as it slid out, guided by a mechanism she couldn’t see. Harlow lunged, catching the bookshelf with her left hand, letting her torch skid to the floor. Her palm slammed against cold bone-smooth stone. It bit. Pain flared, bright and immediate, and the room rang with a sharp metallic squeal as the blade stalled, then accelerated. Harlow shoved the bookshelf hard, forcing it off its path. The shelf jerked, maps rustling. The mechanism screamed again, and the blade snapped back into the wall like an irritated snake. Silence burst after it, sudden and total, like someone cut the power. The suspect stood perfectly still in the dark, watching her hand, watching the blood that had started to run over her knuckles. His grin faded. For the first time, his certainty wavered. He raised his token. Harlow felt the air tug toward the entrance she’d lost. The darkness around the curtain thickened, forming a new seam, like an exit pretending to be a threat. She had a choice again, but it wasn’t hers. The room had decided. The bookshelf lurched, slamming into place with a final, heavy finality. And the darkness in the doorway split open, not to let her out, but to let something in.
