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>

“Don’t touch that chalk line.” Detective Harlow Quinn ducked under the half-hauled shutter and stopped dead on the platform edge. The body lay where no body should have been, draped across a rusted station bench as if someone had posed it for a photograph and lost interest halfway through. Broken tiles glittered under the work lights. Old adverts peeled from the tunnel walls in damp curls. The abandoned Tube station beneath Camden had the stale, buried smell of brick dust, old grease and something sweet that did not belong, lilies left too long in funeral water. A uniform constable looked up from his notebook and stepped back at once when he saw her face. “Sorry, ma’am.” Quinn’s brown eyes moved once across the scene and began sorting it. Bench. Victim. Blood on the third pillar. No drag marks. No obvious weapon. Four officers too close together near the stairs, trampling clean dust with city-issued boots. Her jaw tightened. “Push them back. Two metres from the platform edge. No one breathes on this until the SOCO team finish.” The constable snapped into motion. Quinn pulled on gloves with short, hard tugs. Her worn leather watch sat snug on her left wrist, scratched at the rim, old habit, old companion. She crouched near the bench but did not touch. Male, early thirties. Grey suit jacket, cheap cut. White shirt open at the throat. Hands blackened at the fingertips, soot or residue. Eyes open. Mouth fixed in a strain that looked less like fear and more like surprise. Not mugging. Not random. “Cause of death?” “Pending.” DI Leonard Vale stood near the pillar with his coat unbuttoned and his tie skewed. He held a paper cup he should not have brought anywhere near the scene. “Paramedics gave a rough opinion. Cardiac event, likely brought on by drugs or stress. There’s bruising at the neck, but no clear strangulation. Could be a struggle. Could be collapse. Nasty place for a user to wander into, but Camden gets all sorts.” Quinn did not look at him. “Who found him?” “Urban explorers. Two lads with a camera and more nerve than sense. They legged it when they saw the body, then found a signal near the service tunnel and called it in.” “Names?” “Taken.” “You separated them?” Vale hesitated a beat too long. “They’re upstairs with uniforms.” Quinn rose and turned her head at last. Military precision lived in every line of her body. Vale always noticed it when she went still. Stillness meant disapproval. Motion came after. “‘Upstairs with uniforms’ is not the same as separated.” “They’re kids, Harlow, not cartel witnesses.” “That depends what they saw.” Vale lifted his cup, thought better of drinking, lowered it again. “You walked in less than thirty seconds ago.” “And I already know we’re handling this badly.” Silence thinned the air between them. Somewhere deeper in the tunnel, water ticked into water. Quinn stepped closer to the body. The station itself stretched wide and low, one of the old ghost platforms left to rot after maps forgot it. A string of battery lamps cast crude islands of light. Beyond them, the tunnel mouths gaped black and patient. Old posters for West End shows hung in tatters. Someone had sprayed symbols across the far wall in silver paint, circles and slashes layered over Victorian brick. She looked past the graffiti to the dust on the platform. Disturbed in patches, untouched in others. One set of police prints by the stairs. A scatter from the two explorers. Smaller impressions near the bench. Then something else, faint and wrong, as if the dust had been brushed aside in narrow arcs. “Who searched for the weapon?” “BTP did a sweep before we got here. Nothing obvious.” “Nothing obvious,” Quinn repeated. “That phrase should be struck from police use.” Vale gave a dry laugh. “You going to ban common sense next?” “I’d settle for people using it.” She crouched again, this time beside the victim’s shoes. Expensive polish on cheap leather. Fresh scuff on the left toe. Dust thick on the heel, absent at the sole edge. He had not walked much on this platform. He had stepped here recently, then stayed put, or been placed. “Wallet?” “In his pocket. ID says Martin Keel. Thirty-four. Freelance journalist, if his press card’s genuine.” “Phone?” Vale nodded towards an evidence bag on a crate. “Smashed. Found under the bench.” Quinn held out a hand. A constable brought the bag. The screen had burst inward, not out. Impact from above. One corner carried a smear of dark residue, not blood, more like ash mixed with oil. She held it closer to the light. “Who bagged this?” “PC Redman.” “Did Redman note the residue?” Vale checked his pad. “He wrote ‘grime’.” “Of course he did.” Quinn set the bag down and looked at the victim’s neck. Bruising ringed one side, uneven, too low for hands if someone had throttled him from the front. She leaned nearer. Not bruising alone. Tiny crescent marks sat within the discolouration, paired and regular. “Get me a macro camera.” Vale frowned. “You think that’s bite mark analysis now? We’re not doing junk science before lunch.” Quinn ignored him. Her gaze slid to the victim’s shirt cuff. Fine red grit clung to the fabric. Not brick. Too bright. She rubbed a tiny fleck between gloved fingers. It crumbled into a soft powder that left a rusty stain. Not rust. Pigment. She stood and turned slowly, taking in the wall, the bench, the tracks. The station had not died empty. Someone had made use of it. Along the opposite wall sat three market tables folded flat and shoved under tarpaulins. Crates stacked by a sealed kiosk. Wax on the floor in old drips, black and green. A smell under the lilies, now she had it, sharp and bitter, like burnt herbs and pennies. Vale followed her line of sight. “Squatters. Taggers. Addicts. Pick one.” “No.” That single word cut clean. Quinn walked to the nearest pillar. Blood marked it at shoulder height, six small drops, no spray, no swipe. She bent until her face nearly touched the concrete. The droplets sat on top of the grime, bright and recent. Below them, someone had scratched a symbol into the dirt, then smeared half of it away with a shoe. “What do you see?” Vale joined her with a sigh. “I see a dead journalist in an old station. He came here chasing a story, bought from the wrong people, got dosed or threatened, his heart packed in. The bruise came from a scrap. The blood’s from him hitting the pillar.” “He never hit this pillar.” Vale looked at the body, then back. “Why?” “The height’s wrong. Keel was five foot eleven, thereabouts. If he fell into this, the blood would streak or smear. It dropped straight down. Controlled loss, not impact.” “Someone bled here, then.” “Yes.” “Not exactly earth-shattering.” Quinn pointed with two gloved fingers, neat and sharp. “And the body’s on the bench. Shoes nearly clean. No drag marks, no collapse pattern, no pool under where he should have fallen if his heart gave out. Someone put him there after the event.” Vale’s expression shifted. Annoyance first, then reluctant attention. “All right. Staged. Why?” “To be found.” He spread a hand. “Again, not rare.” “No. But this is.” She moved to the scratched symbol by the pillar. “This was partly wiped, not hidden well, just spoiled. Someone in a hurry who still wanted it unreadable to anyone paying half attention.” Vale squinted. “Looks like random lines.” “It looks like that because whoever did it knew enough to ruin the centre stroke.” “Since when do we consult runes?” Quinn’s eyes flicked to him. “Since a decorated sergeant walked into a locked room three years ago and died with both lungs full of river water.” Vale said nothing. He knew better than to touch Morris’s name directly. The dead still occupied space around her. A scene-of-crime photographer hurried over with the camera. Quinn directed him to the neck marks, the red powder on the cuff, the symbol on the floor, the residue on the phone bag. While he worked, she walked the platform edge in measured steps. The rails below vanished beneath rubble and pooled dark water. Between the sleepers, odd bits of debris had gathered, old bottles, newspaper mulch, a snapped umbrella. Then she saw the gap. One clean rectangle in the filth where something had rested until recently. About the size of a small case. “Who’s been down on the track?” “No one,” Vale said. “Too unstable.” Quinn pointed. “Then explain that.” He climbed down with a torch and crouched near the rectangle. “Could be anything.” “Read me the dust line.” He shone the torch around the edges and grunted. “Object removed after the rest settled. Recent.” “How recent?” “Hours.” “Good. Keep going.” He aimed the beam left and right. A trail of fine scratches led from the empty space to the service tunnel mouth, as if metal corners had scraped over stone. Beside them, those same narrow arcs marked the grime. Vale swore under his breath. “A case on wheels?” “No wheels.” Quinn crouched at the platform edge and studied the pattern. “Too uneven. Carried at first, set down, dragged, lifted again. Two people, one weaker than the other.” “You get that from scratches now?” “I get it from rhythm. Short scrape, pause, deeper gouge where one side dropped. Again and again.” A constable approached, breathless. “Ma’am, one of the lads who found the body said there were candles here when they came in. Lots. Green ones. He thought the officers removed them.” “No one removed candles,” Vale said. Quinn’s head turned. “Bring him down. Alone.” The boy arrived pale and shivering under bravado, camera strap still around his neck. “You saw candles?” “Yeah. Around the bench. And, like, tables. Not normal tables. Stalls. Thought it was some immersive thing at first.” “Why didn’t the attending officers note them?” “I don’t know. They were there, then they weren’t.” Vale folded his arms. “People in shock misremember.” The boy bristled. “I know what I saw.” Quinn held his gaze. “What else?” He swallowed. “A woman was here.” “Police?” He shook his head. “No uniform. Curly red hair. Glasses. She had this old satchel. She told us to leave if we valued our teeth.” Quinn’s eyes narrowed by a fraction. “Did she touch the body?” “No. She knelt by that wall.” He pointed to the opposite side, near the tarpaulins. “Then she looked at this little brass compass in her hand. Weird one, all scratched up, green round the edges. Then she heard us and swore.” The station seemed to contract around that detail. Vale gave Quinn a sideways look. “Friend of yours?” Quinn did not answer at once. Eva Kowalski. British Museum archives. Too curious by half. Too often near the edges of things she should have left buried. “What happened next?” “She said, ‘You saw nothing useful, which is lucky for you.’ Then she went through that tunnel.” He pointed past the service arch. “Not the main one. The little brick one with the iron gate.” “There is no gate,” said Vale. The boy’s face went flat with offended certainty. “There was when I saw it.” Quinn moved before anyone else did. Across the platform, under the torn posters, past the folded tables. The tarpaulins smelled of damp canvas and spice. Under one, she glimpsed a row of empty glass phials nestled in straw. Under another, black feathers tied in bundles with red thread. Vale caught up as she reached the brick archway at the rear of the station. It looked like solid wall from three paces off. Up close, mortar lines told a different story. The bricks inside the arch were newer than the rest, set in a rough seal. On the floor, red powder traced a broken circle. Bone-white chips glittered in the cracks. Vale stared. “What the hell is this?” Quinn knelt and picked up one chip with care. Not plaster. Bone, polished on one side, carved on the other. A token, snapped clean through. Her gloved thumb brushed the carving. A tiny market stall beneath a crescent line. The smell changed first. The stale underground air peeled back. In its place came a rush of cardamom, smoke, hot metal and too many voices speaking all at once behind a wall that should have been mute. The sealed bricks shuddered. Dust hissed from the mortar. Somewhere beyond them, a bell rang once, bright and wrong in the buried dark. Vale stepped back. “Quinn.” A crack split the brickwork from top to bottom, thin as a knife cut, and green light bled through.
