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>

Quinn caught the dead man’s arm before it slipped from the stretcher. “Nobody moves him.” The paramedics froze. One held the corpse beneath the shoulders, the other beneath the knees. A grey sheet sagged between them, heavy with blood. DS Leo Mercer lowered his camera. “We photographed the body.” “You photographed where someone left it.” The abandoned platform beneath Camden had not carried a train in sixty years, yet someone had scrubbed its cream tiles and painted the old signs black. Stalls crowded the track bed. Their patched awnings hung over jars of teeth, caged insects and stoppered bottles filled with pale smoke. Copper lamps cast a sour green glow. The place smelt of hot metal, wet stone and something medicinal that clung to Quinn’s tongue. A market, according to the caller. An elaborate crime scene, according to the warrant. A bloody circus, according to every instinct Quinn trusted. She guided the dead man’s hand back against his chest. His skin had cooled, but his fingers bent without resistance. No rigor in the wrist. The paramedics had found him less than an hour ago. “Put him down. Same position.” “You want him back in the blood?” “I want him back where you found him.” Mercer gestured towards the floor. “His head was there. Feet towards the platform edge.” “Then put him there.” The paramedics lowered the corpse into a dark pool painted across the tiles. The blood had collected inside a ring of white powder. Symbols cut through it, all hooks and open mouths. Three candles burned beside the dead man’s head. Their flames gave off no smoke. Quinn crouched. The victim looked around fifty, with a narrow face and a beard clipped square beneath his jaw. Someone had dressed him in a black wool coat over striped pyjamas. His bare feet had turned grey at the heels. A deep wound crossed his throat. Mercer folded his arms. “Anonymous call came through at 3.17. Male voice, no accent I could place. Said there’d been a killing at the Veil Market. Gave directions and told control to bring a bone token.” He pointed towards a numbered evidence marker. A yellowed disc lay inside a clear bag. Someone had carved a door into its surface. “The entrance wouldn’t open until I put that in the ticket slot.” “You put unidentified human remains into a machine?” “It looked bovine.” “It has a filling.” Mercer’s mouth tightened. Quinn glanced down the platform. Uniformed officers stood in pairs beneath the black station signs. None had wandered among the stalls. Good. A cage the size of a hatbox clicked each time someone passed, though nothing occupied its interior. Beside it, silver spoons shifted in a velvet-lined case, arranging themselves into neat rows before scattering again. A handwritten notice hung from one stall. NO REFUNDS FOR CURSES ACQUIRED THROUGH MISUSE. “Where are the traders?” “Gone. Food still warm in two stalls. Cash boxes open. No signs of a rush.” “They left money?” “Old coins, foreign notes, teeth. For all I know, that is the money.” “And witnesses?” “One.” Mercer looked towards the far end of the platform. A woman sat beneath an enamel WAY OUT sign with a constable beside her. Curly red hair spilled around her round glasses. Her worn leather satchel rested between her boots, open and packed with books. She kept tucking the same curl behind her left ear. Quinn recognised her from the preliminary identification check. Eva Kowalski. Twenty-six. Oxford graduate. Research assistant at the British Museum. Access to restricted archives, several sealed collections and enough dead languages to make a magistrate nervous. “Her account?” “She arrived after the victim died. Says she came to buy a compass.” “A compass.” “Not for finding north.” Quinn looked at the dead man again. “Nothing down here finds north.” She pulled on nitrile gloves and touched two fingers to the blood beside the victim’s shoulder. The surface had thickened, but the edge near his coat remained glossy. Mercer crouched opposite her. “Throat cut inside the circle. Powder contains salt, crushed bone and silver filings. Dr Patel says the cut severed both carotids. He bled out in minutes.” “Then where’s the spray?” Mercer surveyed the tiles. “Under him.” “Pooling, yes. Not spray.” Quinn pointed to the nearest wall. It stood less than a metre from the corpse, its pale tiles unmarked. “A severed carotid throws blood. The candles are clean. The powder is clean. His coat collar is clean.” “The wound could have opened after his heart stopped.” “Then he didn’t bleed out from it.” Mercer’s gaze settled on the pool. “Someone poured the blood around him.” “And put the wound where we’d stop looking.” Quinn lifted the coat collar with a pen. Beneath it, bruises circled the victim’s neck. Four dark marks on the left. One on the right. “A hand?” “Too wide. Thumb should sit higher.” “Some sort of restraint?” “Something forked.” Mercer photographed the bruising. His flash revealed a dull glint within the victim’s beard. Quinn parted the coarse hairs. A line of tiny metal staples ran beneath the jaw, pinning a strip of translucent material to the skin. Mercer leaned closer. “What is that?” “Not his throat.” Quinn caught the edge with tweezers. The false skin peeled away. Beneath it, the victim’s throat remained intact. The cut belonged to the prosthetic. One paramedic swore. Mercer rose and turned towards the officers. “Scene log. I want the names of everyone who touched him.” Quinn stripped away the remaining membrane. It carried tubes no thicker than veins, each filled with blood. Pressure from the body’s weight had emptied them into the pool. “Stage blood?” “Human blood.” “You know that by looking?” “I know stage blood doesn’t clot.” Quinn ran her gaze over the body from head to foot. The striped pyjama jacket sat buttoned to the collar. One button had slipped into the wrong hole, pulling the fabric across his chest. His black coat bore pale dust along the back and sleeves, but none on the front. His bare soles looked clean. The platform did not. Grit coated every tile. It had settled into the mortar and formed soft drifts beneath the benches. Even the paramedics’ overshoes carried grey smears. “He didn’t walk here.” “We established that.” “No drag marks. No trolley tracks. Four people carried him, minimum.” “Or two strong people.” “Not in this passage.” She nodded towards the narrow arch behind the platform. Iron studs jutted from both walls. Anyone carrying a body between them would have turned sideways. Two people could not manage it without striking his coat or feet. Mercer examined the arch. “Four carriers leave eight sets of prints.” “And we have?” “Paramedics, Kowalski, three uniforms, me.” “Before you arrived.” Mercer’s expression hardened. “None.” Quinn looked towards the market stalls. Dust lay across the platform, but the track bed below looked damp and black. A shallow rail cart sat between two rows of booths. Its wooden deck bore a body-shaped clean patch. “There’s your hearse.” They climbed down from the platform. The Veil Market crowded around them. Bundles of dried roots hung from brass hooks. A glass tank contained dark water and a single white glove, its fingers flexing against the glass. Shelves groaned beneath old books chained shut through their spines. The rail cart’s iron wheels rested on tracks that ended at a brick wall. Mercer scraped dirt from one wheel with a swab. “Fresh grease.” “Blood in the grain.” A brown line had soaked into the cart’s deck. Quinn crouched and followed it to a knot in the wood. The stain stopped there with a clean vertical edge. “Something covered this section.” “A sheet?” “Canvas. Heavy enough to hold its shape.” Mercer studied the dead tracks. “Cart came from nowhere, delivered the body, rolled back to the wall.” “Or the wall isn’t a wall.” Mercer knocked on the bricks. Solid impacts travelled along the tunnel. “Nothing hollow.” “No door marks either.” “That supports wall.” “It supports good workmanship.” A soft metallic tick came from beneath the cart. Quinn reached under it and found a small brass compass wedged behind the axle. Green verdigris filled the grooves of its casing. Protective sigils covered the face in tight circles. Its black needle quivered, then pointed towards the brick wall. Mercer crouched beside her. “Kowalski’s purchase?” “She said she came to buy one. She didn’t say she bought it.” Quinn bagged the compass and straightened. At once, the needle spun inside the evidence bag. It turned past the wall, passed Quinn, then snapped towards the platform. Towards Eva Kowalski. Mercer watched it tremble. “Magnet in her satchel.” “Then it would have pointed at her before I lifted it.” Quinn climbed back onto the platform. Eva’s constable shifted aside at her approach. Up close, the young woman looked less frightened than furious. Chalk dust marked one knee of her corduroy trousers. A fresh scratch crossed the back of her hand. Quinn held up the evidence bag. “You came to buy this.” Eva pushed her glasses higher. “No. I came to identify it.” “Your statement says buy.” “Your sergeant paraphrased. Badly.” Mercer stopped behind Quinn. “I wrote down your exact words.” “You omitted the qualifying clause.” “You said, ‘I came for the Compass.’” “Yes. In English, prepositions carry broad burdens.” Quinn placed the bag on the bench between them. The needle pointed at Eva’s chest. “What does it do?” “It locates ruptures.” “In what?” “The partition between adjacent states of existence.” Mercer gave a dry laugh. “Doors to other worlds.” Eva tucked her hair behind her left ear. “If reducing the concept helps you digest it, yes.” “And you locate these doors for the British Museum?” “The Museum misfiles objects. I correct its errors.” “Objects such as this?” “That is a Veil Compass. A Shade artisan crafted it. The sigils protect the user from directional contamination.” Mercer glanced at Quinn. “Directional contamination.” “Space does not behave well near a rift.” Quinn nudged the bag. The needle kept its aim on Eva. “Why does it point at you?” “It doesn’t.” “It has a funny way of showing that.” “It points through me.” Eva turned on the bench. Behind her stood a sealed service door. Quinn looked from the compass to the door. Rust covered its lock. Dust lay unbroken along the threshold. “What’s behind it?” “An access stair, according to the station plans.” “According to the Market?” “The Market never shares plans.” Quinn studied Eva’s scratched hand. “How did you hurt yourself?” “A bookseller objected when I opened a locked cabinet.” “Where is this bookseller?” “Gone.” “Convenient.” “For someone. Not for him. He left both hands behind.” The constable’s face lost colour. Mercer crouched beside the satchel. “Open it.” Eva placed one palm over the flap. “You have no idea which items in there regard a search as consent.” Quinn met her green eyes. “You can open it, or my colleague can discover how literal that warning is.” Eva held Quinn’s stare, then unbuckled the satchel. Books packed the interior. A notebook. Cotton gloves. Two pencils. A small jar of black grains. Beneath them lay a folded sheet of station plans and a second bone token. Mercer lifted the token with forceps. “One for the entrance. One for the exit?” “The Market moves every full moon. Entry tokens decay after use.” “This one looks healthy.” “So does arsenic.” Quinn unfolded the station plans. Eva had marked the disused platform in red. A service corridor ran behind the sealed door and ended at a lift shaft filled with concrete in 1964. Someone had added another line in blue ink. It passed through the shaft, crossed the platform and continued into blank paper. The route ran beneath the corpse. “Your work?” “No.” “Your map.” “Taken from the Museum archive at noon. The blue line appeared after I entered the Market.” Mercer tapped the jar. “And the dirt?” “Not dirt.” “What is it?” “Residue from a closed rift.” Quinn picked up the jar. Black grains clung to the glass in branching patterns. Three years ago, she had found the same residue beneath DS Morris’s fingernails. The forensic report had called it industrial carbon. No factory within ten miles had produced the trace elements in the sample. The report had vanished from the case file two weeks later. Quinn’s worn leather watch creaked as she tightened her grip. “Where did you get this?” Eva’s eyes dropped to the watch, then returned to Quinn. “From the place your partner died.” Mercer went still. Quinn placed the jar down with care. “His body was never found.” “No.” “You have five seconds to explain how you know his name.” “I don’t know his name.” “You said partner.” “The man on the platform has a message for you.” Quinn crossed the distance before the constable could react. She caught Eva by the front of her coat and pulled her upright. “What message?” Eva did not resist. Her glasses slipped down her nose. “Check his mouth.” Mercer reached the corpse first. He knelt, gripped the victim’s chin and forced the jaw open. Something white rested beneath the tongue. He drew it out with forceps. A Metropolitan Police evidence label. Faded ink covered one side. MORRIS, D. S. CASE 4416. Quinn released Eva. “That number isn’t his case.” Mercer turned the label over. On the back, someone had written one word in fresh red ink. HARLOW. The three candles beside the corpse went out. A sharp crack travelled beneath the platform. The white powder ring split from end to end. Blood drained into the fracture, vanishing faster than the pool could feed it. The Veil Compass whirled inside its bag. Mercer drew his baton. “Everyone back.” The sealed service door buckled inwards. Rust burst from its hinges. Something struck it again, bending the metal around the frame. Eva snatched her satchel. “That is not a rift.” The third impact tore the door free. It sailed across the platform and crushed the bench where Eva had sat. Beyond the doorway, no stair remained. Black tiles stretched into a tunnel lit by copper lamps. A rail cart rolled from the darkness, its wheels clacking over tracks that crossed empty air. A man stood upon it. His suit hung in wet strips. Black grains filled his eyes. Around his left wrist, he wore the braided cord Morris’s daughter had made for him at school. He raised a service pistol and aimed it at Quinn. “Harlow.” The corpse behind Mercer opened its eyes and seized his throat.
