You are an expert and award-winning novel writer in the dark Mystery 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 mystery genre. A detective arrives at a crime scene in an unusual location. Something is wrong — the evidence doesn't add up. A colleague is present, offering a different interpretation. Through careful observation and deduction, the detective begins to see what others have missed. 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>

“Take your foot off the chalk.” Detective Harlow Quinn caught the constable by his stab vest and hauled him backwards. His paper overshoes skidded across the platform, smearing grey dust but missing the thin white line by a finger’s width. “Nobody moves.” The abandoned station swallowed her order and returned it in scraps. Nobody moves. Moves. Moves. Six officers froze among the remains of the Veil Market. Canvas stalls crowded the old platform, their striped awnings sagging beneath soot. Glass jars held teeth, feathers and pale things that contracted when torchlight touched them. Copper cages hung from hooks along the tiled wall. Each cage stood open. A ticket booth squatted at the platform’s far end, its windows painted black from within. Between the rails lay a dead man in a brown wool coat. Quinn released the constable. “Name.” “PC Harding, ma’am.” “Harding, who authorised entry?” “The call came through as an assault in progress. Uniform reached the gate and found it unlocked.” “Which gate?” He pointed towards an iron grille beneath the old EXIT sign. A length of chain hung from it, each link thick as a thumb. No cut marks scarred the metal. The padlock remained closed. Quinn studied the gap where the chain passed through the bars. Someone had unthreaded it without opening the lock. “Who touched the chalk?” “No one, ma’am.” “You almost did.” His mouth tightened. Quinn checked the worn leather watch on her left wrist. Thirty-seven minutes since the first call. Long enough for uniforms to walk through every useful trace and swear they had touched nothing. A camera shutter clicked. “Stop taking photographs.” The crime scene photographer lowered his camera. “They’re for the record.” “The record can wait until I know whether the flash wakes anything.” A soft voice rose behind one of the stalls. “Sensible.” Eva Kowalski stepped out with both hands raised. Her curly red hair had gathered soot, and her round glasses sat crooked on her freckled face. The strap of a worn leather satchel crossed her chest. Books crowded its open mouth beside bundles of paper, a magnifying lens and a linen pouch stained dark at the corners. Quinn’s hand moved to the baton at her belt. “Who let you in?” “Detective Sergeant Vale.” “Vale isn’t here.” “That has become obvious.” Eva tucked a curl behind her left ear. Quinn glanced at Harding. “The red-haired woman. Did she enter before or after you?” “She was here when we arrived.” Every face on the platform turned towards Eva. Eva lowered her hands by inches. “That sounds worse aloud.” “It sounded poor in my head.” “I had a token.” Quinn held out her palm. Eva drew a small disc from her coat pocket. Bone, polished by years of use. A hole pierced its centre, and cramped symbols ringed its edge. Quinn took it with a gloved hand. “Human?” “Not all questions improve with an answer.” “Mine do.” “Finger bone. Adult. The carving predates the death.” PC Harding swallowed. Quinn slipped the token into an evidence bag. “You’ve just lost your fare home.” “This station isn’t home.” “You know what I meant.” Beyond Eva, the platform ended at a bricked tunnel. Old cream tiles lined the walls, split by damp and roots. Signs still named a station that had vanished from public maps decades ago. Yet fresh tracks cut through the grime. Narrow wheels. Boot soles. One set of prints ended against solid brick. The place smelled of paraffin, stale incense and pennies sucked between teeth. Underneath clung a sweet trace, like pears rotting in a locked cupboard. Quinn nodded towards the body. “Walk me through it. No folklore.” “That leaves you with a corpse and poor lighting.” “Start there.” Eva approached the platform edge but stopped short of the chalk line. It formed no circle. Instead, it ran from the black ticket booth, passed beneath two stalls and crossed the platform before descending over the edge. Four short bars interrupted it beside the body. “The dead man is Silas Venn. He traded in routes, names and protected addresses.” “People traffic?” “Information.” “Information traffics people.” Eva’s lips thinned. “He came here to sell the location of a breach.” “A breach in what?” Eva pointed at the tunnel wall. “Reality, if you require the blunt version.” Quinn crouched beside the chalk without crossing it. The dead man lay on his back between the rails, arms loose, head angled towards the bricked tunnel. An old black iron knife rose from his chest. No blood marked the coat around it. A dark pool spread beneath his right hand and soaked into the wooden sleeper. “Your interpretation?” “Someone silenced Venn before the sale. The knife pinned his shade to his body. The chalk held the breach shut. When he died, the protections failed.” “Convenient.” “Accuracy often lacks charm.” Quinn looked at Eva. “You identified him without seeing his face.” A pause. Small, but present. Eva tucked the same curl behind her ear. “His coat.” “Brown wool has become a unique identifier?” “The buttons. Venn used grave coins.” Quinn examined them. Dull silver discs fastened the coat, each stamped with a closed eye. “Grave coins belong on the dead.” “In some traditions.” “In yours?” “I don’t own a tradition.” “Everyone owns one. Most call it habit.” Quinn stepped down from the platform. The rails gave a faint metallic hum beneath her boots. Harding started forwards. “Stay there.” She crouched near the body. A protective suit covered her clothes, but the cold from the track seeped through the knees. Venn’s face had the loose, waxen look of a shop mannequin left near a radiator. Grey hair framed a narrow skull. His eyes remained shut. A blue mark circled his throat. The knife had entered between the third and fourth buttons. Quinn pinched the coat and lifted it away from the shirt beneath. White cotton. Unbroken. “Your assassin has unusual technique.” Eva peered down. “What did you find?” “The knife pierced the coat. Not the shirt.” Harding leaned over the platform. “So it didn’t kill him.” “No.” Quinn ran two fingers beside the iron blade. It pierced several folded layers of wool, then lodged in a wooden slat strapped across the dead man’s chest. Someone had dressed him around it. “The knife’s a prop.” Eva’s face lost its dry amusement. “That symbol is not decorative.” “It can be genuine and planted.” Quinn touched the blue ring around Venn’s throat. Grease came away on her glove. “Stage paint.” “The cause of death could still be strangulation.” “No burst vessels in the eyes. No damage beneath the colour.” Quinn shifted to his hand. The dark pool had reached the next sleeper, though the platform sloped in the opposite direction. She touched its edge with a swab. Thick. Cold. It clung in a glossy thread. “Not blood.” Eva inhaled through her nose. “Lamp oil, iron filings and binding resin.” “You can smell binding resin?” “I work in the British Museum’s restricted archives. Half the collection leaks.” Quinn sealed the swab. “Someone wanted the scene read at a glance. Knife. Blood. Ritual marks. Dead information broker.” “And you think he died elsewhere.” “I think we haven’t established that he died.” Harding let out a short laugh, then stopped when Quinn looked up. She pressed two fingers to Venn’s neck. Cold skin. No pulse. Rigor held the jaw but not the fingers. The contradiction scratched at her. She lifted his wrist. Green powder coated the pads of his thumb and forefinger. Near his palm lay a small brass compass, its casing furred with verdigris. Protective sigils crowded the glass face. The black needle quivered towards Venn’s sternum. Eva’s satchel slipped from her shoulder. “Don’t touch that.” Quinn’s hand stopped above it. “Why?” “It’s a Veil Compass. A Shade artisan made it. The needle points towards the nearest rift.” “It points at him.” “Yes.” “Then your breach has grey hair and poor tailoring.” Eva knelt at the platform edge, her green eyes fixed on the compass. “Venn carried it. The patina stained his fingers.” Quinn compared the powder on Venn’s skin with the compass. Verdigris coated every ridge of the casing in an even bloom. No clean marks showed where fingers had gripped it. “No.” “The colour matches.” “The transfer doesn’t.” She lifted the compass by its chain. The needle swung towards the body, struck the edge of its housing, and trembled there. Beneath the compass, the sleeper showed a clean circle in the dust. Someone had placed it after the dust settled. Quinn held it towards Venn’s feet. The needle still aimed at his chest. She moved it past his shoulder, then over his head. The needle reversed and followed the sternum. Eva took off her glasses and polished them on her sleeve, though the lenses looked clean. “This is wrong.” “An expert opinion at last.” “A human body cannot contain a stable rift.” “Stable?” The needle rattled against the glass. Eva put her glasses back on. “That isn’t stable.” Quinn studied the rails, the body and the four short bars cut into the chalk line. No officer had crossed the line, according to Harding. Yet Venn lay beyond it. Dust covered the sleepers except around his shoulders and shoes. No drag marks led from the platform. No footprints approached him. She looked at the coat again. Its hem rested beneath his calves. The fabric carried no grime from the track bed. Placed from above. Lowered straight down. Her gaze travelled to the overhead tunnel. No ropes. No pulleys. Only cables, flaking tiles and old iron brackets. Then she saw the fibres. A thin black thread clung to a bracket above the body. Another caught on Venn’s collar. Not thread. Hair. Long, coarse and stiff enough to hold a curve. Quinn rose. “Harding, who found the black booth open?” “It wasn’t open.” “The door.” “There isn’t one.” Quinn climbed onto the platform and crossed to it. The booth’s wooden panels met the tiles without a gap. Black paint covered the windows, thick and tar-like. A brass speaking grille sat at mouth height. Below it, someone had carved four vertical cuts into the ledge. Four cuts. Four bars in the chalk. She held the Veil Compass near the grille. The needle pointed behind her, towards Venn. Eva followed at a distance. “The compass settles on the closest opening, not the largest.” “Then the corpse is closer.” “Much.” Quinn crouched beside the base of the booth. Dust lay thick along the skirting except for one clean patch shaped like a knee. She pressed her torch close. A short red hair glowed against the black wood. Eva’s hand rose towards her left ear, then stopped. Quinn picked up the hair with tweezers. “Your token got you in. What got you out?” “I haven’t left.” “Before tonight.” “I’ve used the Market twice.” “And the booth?” “I’ve never touched it.” “Your hair disagrees.” “Hair travels.” “It does when carried.” Eva glanced towards the officers. Her fingers closed around the strap of her satchel. Quinn saw the movement. “Don’t.” “I need a book.” “You need a solicitor.” “I need page two hundred and eleven of Halberg’s Threshold Anatomy.” “You remembered the page.” “I remember useful things.” “Then recite it.” Eva held Quinn’s stare. “‘A false corpse presents the image of death while serving the appetite of a door. Do not bleed it. Do not name the dead it resembles. Above all, do not break the line that denies it passage.’” Silence tightened across the station. Quinn turned towards the chalk. Harding stood inside it. Not across it. Inside. The white marks did not form one line. They formed the edge of a vast shape that continued beneath the stalls, rails and booth. The four small bars beside the corpse joined a larger sigil hidden by market debris. The constable Quinn had pulled back had not been about to enter the design. He had been about to leave it. “Everyone freeze.” The photographer lowered his gaze to his shoes. His left heel rested on the chalk. A white smear marked the sole, and a narrow break split the line beneath him. The black pool between the rails changed direction. It crept uphill. Eva pulled Halberg’s Threshold Anatomy from her satchel and opened it in one motion. Pages fluttered beneath her hands. “No blood,” she murmured. “No name. No broken line.” “The line’s broken.” “Then don’t name the body.” Quinn looked at the waxen face between the rails. The bone structure had shifted. The chin looked broader now. Familiar. Her chest locked. Three years vanished in the angle of that jaw, in the pale scar beneath the lower lip. DS Morris had earned that scar from a bottle outside a pub in Whitechapel. Quinn had driven him to hospital while he bled into her spare shirt and complained about the stitching. The corpse opened its eyes. Morris stared up at her. “Harlow.” The voice came from the speaking grille behind Quinn. Every torch on the platform died. Glass shattered among the stalls. Something heavy dropped from the ceiling and struck PC Harding hard enough to crack tile. Officers shouted. A gun fired, and the muzzle flash caught a nest of black limbs unfolding above the rails. The Veil Compass spun in Quinn’s hand. Morris’s corpse sat upright. “Don’t let it wear me.” His mouth stretched past the limits of his face, and the broken chalk line burst into flame.
