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 ducked under the police
tape and caught the constable by the sleeve before he could bar her again. “Move.”
He glanced at her warrant
card, then at the body on the platform, then back at the sharp set of her jaw. His hand dropped.
The abandoned station gaped beneath
Camden like a throat. Old tiles sweated grime.
A row of stripped advertisement
frames lined the wall, each one holding a different
charm
, sigil, or scrap of paper now, all of it snatched down and bagged by forensics. The air carried damp brick, hot wiring, and something metallic that clung to the back of Quinn’s tongue.
Eva stood near the yellow
line, round glasses low on her nose, one hand hooked through the strap of her worn leather satchel.
She looked up as Quinn
came down the steps. “You’re late.”
Quinn stopped beside the prone
figure wrapped in a white sheet. One gloved hand protruded from the edge, fingers blackened at the nails. “You sounded nervous on the phone.”
Eva tucked a curl behind
her left ear, then looked past Quinn towards the far tunnel. “I have reasons.” Quinn crouched.
The sheet had soaked through
at the chest. Not blood everywhere, not the kind that sprayed and splashed and marked half the room. A dense, dark stain, contained. Neat. Too neat.
The dead man’s boot lay
a pace away, sole up, with a smear of chalk across the tread. “Who found him?” “A trader from the south passage. He heard the alarm wards sing and ran.” “Alarm wards.” Eva’s mouth tightened. “This place runs on more than locksmiths and luck, Detective.”
Quinn lifted the sheet with
two fingers.
The victim’s face had gone
waxy and grey, mouth open in a small, surprised oval.
A line cut across his
throat, shallow enough to look casual, deep enough to finish the work. No blood pooled under his head.
The tiles beneath him shone
clean. Quinn let the sheet fall. “Someone moved him.” Eva blinked once. “No one moved anything. Not through the upper platform. The market wards would have snapped like wire.” Quinn rose and turned in a slow circle. A collapsed stall sat near the ticket barrier, its cloth canopy cut open from the inside. Bottles lay in a broken crescent under a bench. One glass vial still rolled against the rail, tapping tick-tap, tick-tap, each click like a tiny insult. A brass lantern stood upright beside the wall, its wick cold.
Whoever had left it there
had not rushed. She pointed. “Those bottles sit in a line. Not a smash. Not a scramble.” Eva adjusted her glasses and followed the line with her eyes. “Panic after a breach.” “No.” Quinn stepped to the stall and lifted a fallen wooden sign. Blood marked the underside in a narrow crescent. “If he went down here, this sign should have caught the spray. Nothing on top. Only under. He was on his back when this hit.” Eva’s gaze
flicked
to the sheet, then to the sign. “Or the sign fell after he died.” “Then where did the blood on the underside come from?” Eva said nothing. Quinn walked to the far wall, where the tiles had cracked around an old service hatch. Someone had painted a thin ring of white ash around the frame. Half of it had
been smeared
by a shoe. Quinn crouched again and touched the floor beside the hatch. Fine grit. Not platform dust. Fine as flour. “Bone ash.” Eva gave a short, uneasy breath. “From a sealing rite.” Quinn looked up at her. “You came to the same station and drew a different conclusion.” “I came after the trader rang the archives line. The market keeps records in a dozen dead scripts and three living lies. I thought I could identify the victim from the sigils on his cuffs.” “Could you?” Eva unhooked her satchel and opened it. Books and papers shifted with a dry rasp.
She pulled out a folded
photograph and handed it over. The dead man, alive, stood in front of a stall stacked with candle jars and powder bags.
He wore the same dark
coat, the same narrow mouth. In the image, a small brass compass hung from a cord at his neck. Quinn stared at the object. The face in the photo showed a ring of protective sigils
etched
into the brass. Verdigris clung to the casing. “That’s a Veil Compass.” Eva nodded. “Shade work. Not common. Not cheap. It points to the nearest supernatural rift or portal.” Quinn handed back the photograph. “So he carried a guide to the nearest hole in the world, then got himself cut in a sealed market station.” Eva’s eyes sharpened. “You’re looking at the wrong wound.” Quinn turned towards the body. “The throat says murder.” “The throat says closure.” Quinn rose in one smooth motion. “Explain.” Eva looked at the dead man again, and when she spoke, her voice had gone flat with concentration. “The cut lies above the artery. It bled, but not enough to kill him on the spot. The mouth opened because the lungs filled after he stopped breathing. He did not die from that blade first. He died from the shock of crossing a boundary, then someone finished him.” Quinn’s brow lifted. “Boundary.” Eva pointed at the ash ring around the hatch. “Containment. This station used to sit over old service routes. The Veil Market moved in because the underground geometry bent here. The traders keep a working edge on the place. Something opened. Someone dragged him through, killed him elsewhere, then brought him back to the platform to make it look like a market hit.” Quinn studied her for a beat. “You said dragged.” Eva frowned. “No.” “You did.” “I said brought back.” “Choose words
carefully
.” Eva’s fingers tightened on the satchel strap. “Fine. Carried. Moved. The point stands.” Quinn crossed to the victim’s boots. One toe cap bore a crescent of wet clay.
She rubbed it with a
gloved thumb, then held her hand to the lamp light. “Not platform clay. Tunnel clay.” Eva stepped closer. “Where would he have got that?” “From below.” Quinn walked to the edge of the platform and crouched beside the track bed. The rails had vanished into blackness. On the wall, just above where the tunnel mouth narrowed, she spotted a smear of soot and a strip of fresh plaster. Someone had covered a breach in haste. She touched the plaster.
It crumbled at once, revealing
a narrow seam beneath. “Someone patched this after the body came through.” Eva’s face changed. “You said patch.” Quinn stood and brushed grit from her fingers. “Someone wanted a clean story. Market murder. Occult collapse. Easy fit for the file.” “And you don’t accept easy fits.” “No.” From the ticket booth, a man in forensic whites looked up and held a plastic bag between two fingers. “Detective. Found this stuffed in the dead man’s coat. Might interest you.” Quinn took the bag. Inside sat a small bone token, carved with shallow notches, the kind used to cross into the market. One edge had
been snapped
fresh. Eva exhaled through her nose. “He got in legally.” Quinn turned the token once in her palm. “He got in carrying proof he knew the rules.” “Which means?” “Which means he wasn’t some lost fool who wandered into a trap.” Quinn slipped the token back into the bag and gave it to the forensic man. “Check his pockets for wax, not just weapons. Check his cuffs for underground soot. Check his teeth.” The man blinked. “His teeth?” “Do it.” He moved off. Eva folded her arms. “You think he swallowed something.” “I think he carried something that mattered more than money.” “You do enjoy sounding ominous.” “I enjoy being right.” Quinn stepped to the dead man’s left hand and lifted it with two fingers. The wrist had a shallow bruising, almost hidden under the cuff. A band had sat there recently, a watch or bracelet. She looked at Eva. “Did he wear one?” “No. He came from the south passage before dawn and left no time for such details.” Quinn held the wrist under her gaze. “Wrist marks say otherwise. Something bit hard there. Not a cuff. A clasp.” Eva’s
eyes narrowed
behind her glasses. “Like a compass chain.” Quinn did not answer.
She knelt again and pressed
the dead man’s sleeve back from the wrist. A crescent of verdigris had rubbed into the skin. A coppery smell rose as she touched it, sharp enough to sting. “Someone took the compass.” Eva’s voice dropped. “Why would they leave the body and take the compass?” “Because the compass points at the breach.” Quinn glanced towards the patched seam in the wall. “And because the person who took it needed the breach open.” The platform went still.
Even the forensic man stopped
moving. A hard
silence
crawled through the station, broken only by the old electrical buzz and the faint tick of glass against rail.
Then the brass lantern by
the wall lit. No hand touched it. No match flared. The wick caught in a clean blue tongue of flame. Eva took one step back. Quinn had already drawn her weapon. “Do not move.” The lantern flame bent towards the seam in the wall. The ash ring around the hatch shivered. Fine grit slid across the floor in a whispering line, as if something underneath had just inhaled. One of the dead advertisement frames rattled hard against the tiles. Eva stared at the wall. “That is not ward behaviour.” “No.” The patched plaster cracked from the inside. A thin line split across it with a sound like fingernails on glass. Quinn advanced one pace, gun raised, eyes fixed on the widening seam. The forensic man shouted from the track bed and stumbled backwards, one boot skidding on loose gravel. The lantern flame snapped green. Something hit the other side of the wall with enough force to make the tiles jump. Then the seam tore open, and a hand came through, black with soot, fingers splayed and clawing for the platform edge.
