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 bag that compass.” The scenes-of-crime officer froze with the little brass case pinched in her gloved fingers. Quinn stepped under the tape, her coat skimming a crate of cracked apothecary bottles, and held out her hand. The abandoned platform spread out beneath Camden like a secret someone had built and then denied. Old white tiles sweated damp. Faded Underground roundels clung to the walls. Between them stood a line of market stalls made from railway trestles, velvet drapes, bent brass hooks and old fruit crates. Empty cages hung over the track bed. Candle grease spotted the concrete. Copper stung Quinn’s nose. Not just blood. Incense too, bitter and sweet, with a sharp note of cloves. Mercer waited by the body with a notebook folded in his fist. “You’re late.” “I came from a stabbing in Kentish Town. This had better beat it.” He gave the platform a short sweep of his hand. “Bloke knifed at a goth car boot sale in a dead station. You tell me.” Quinn took the compass. Verdigris rimmed the hinge. Fine sigils ringed the face, too neat for tourist rubbish, and the black needle did not settle north. It twitched, swung, then fixed on the tiled wall at the far end of the platform. She closed the lid. “Who found him?” “Transport maintenance team. They came down after someone tripped a heat sensor on the service line. Found the market half packed, no punters, no traders, one body.” “Names.” “Victim carried ID for Adrian Weller, thirty-eight, antiquities consultant, which often means thief with receipts. No phone. No murder weapon. No witnesses worth the paper. Uniform found the gate at street level chained from the inside.” Quinn looked up. “From the inside.” “Exactly. So one of them locked up and vanished before the first unit got down here. There’s your mystery, wrapped and ribboned.” She crouched beside the body. Male. Well fed. Fresh shave. Good coat, better shoes. He lay on his side near the tunnel mouth, one arm trapped under him, the other crooked across his chest as if someone had arranged it and lost interest halfway through. Blood had dried in a dark fan across his collar and the tiles beside his head. Mercer leaned in. “Single throat cut. Fast. Likely a deal gone wrong. There’s a till over there with no cash, and half these stalls sold contraband by the look of it.” Quinn touched the leather sole of the dead man’s right brogue. Clean. Too clean. The maintenance stair above had shed rust, wet grit and ancient oil all the way down. Her own boots wore an orange smear from heel to toe. She lifted Weller’s foot higher. White dust clung to the edge of the sole. Plaster dust. “Not from the stairs,” she said. Mercer snorted. “He didn’t float.” “He didn’t walk through the route we used.” “He had another way in.” “So where is it?” Mercer spread his hands. “It’s Camden. Every wall has a rat hole.” Quinn moved to the wound. The cut opened the front of the throat in a neat, brutal line. She studied the edges. They looked wrong. Too smooth. Too dark. “Halim.” The SOCO officer stepped forward. “Yes, ma’am?” “Did you get a temperature on the wound?” “Still warm when we logged it.” “Burning?” Halim blinked. “Not burning. Warm.” Quinn pointed to the blackened edges. “That isn’t a knife cut.” Mercer folded his arms. “Looks like a knife cut.” “No tearing. No ragged tissue. The edges sealed.” “With what, a chef’s blowtorch?” Quinn did not answer. She opened Weller’s coat instead. Wallet in the inside pocket. Cards intact. Cash clip still there. Not robbery. In the breast pocket she found a bone token, thumb-sized, smooth on one side and carved on the other with a crescent shape that looked too much like a row of teeth. In the other pocket sat a folded museum slip. Mercer peered over. “What’s that?” She opened it. British Museum, Restricted Archives. A request number. A handwritten note beneath it in neat dark ink. E. Kowalski, retrieval pending. Threshold Instruments, folio IV. Veil Compass, migration records. Mercer read over her shoulder. “Threshold instruments. Christ. He came down here to buy magic beans.” “He came down here for this.” Quinn held up the compass. Mercer scratched his jaw. “Or he bought that tat in Camden High Street and wanted to play Indiana Jones in a tunnel.” Quinn slipped the note into an evidence sleeve and rose. The market drew her eye now in a different way. Not random junk. Not a squatter camp. The nearest stall held labelled drawers. Teeth. Pins. Keys. Dried herbs bound in black thread. Another displayed knives, each laid in exact rows by size. A chalkboard at the back listed stall fees and fines in a cramped mirrored script, then switched halfway into plain English. NO IRON ON THE PLATFORM NO NAMES IN TRADE BONE TOKENS ONLY VEIL MARKET, HOUSE RULES Mercer followed her gaze. “Cute branding.” “Organised,” Quinn said. “Disciplined. Look at the spacing. Every table aligned. Every route kept clear. This wasn’t a rave. This was business.” “Illegal business still ends in a cut throat.” “It does. It usually leaves panic behind as well.” She pointed. A stool lay overturned near the far stall, but the jars on the shelf above it still stood in a straight line. A kettle sat on a brazier, cold on top but warm at the iron base. A ledger remained open with figures entered in different inks and different hands. Whoever had left, had left fast, yet they had not grabbed the loose coins, not the knives, not the boxed powders wrapped in wax paper. “They ran from one thing,” she said. “Not from us. We were nowhere near this place when they moved.” Mercer looked at the chained gate in the distance, then back at her. “You’re dressing up a black market murder because you miss proper puzzles.” She ignored that. The needle inside the compass pressed against the lid as if it wanted out. She opened it again. It swung, held hard, and pointed to the end wall by the tunnel mouth, the same wall beside Weller’s body. She crossed to it. The tiles there looked older from a distance, newer up close. Their glaze held a clean shine under the grime. Fresh work disguised as rot. She ran a gloved finger across the grout. Fine white dust came away on the latex. “Fresh set.” Mercer stepped up beside her. “That wall’s original.” “No. The station’s grout is dark, coal grit, age, seep. This section is chalky. Someone patched it recently.” “With what?” “Plaster and hurry.” She crouched again. The floor in front of the wall held scuffs, half-moons cut through the dust by shoe leather. One large. One smaller. A heel mark dug deep at an angle, the kind a person left when another person shoved them backwards. The marks stopped at the wall. No prints led away. Mercer saw them now. “Hidden door.” “Not on hinges.” “How do you know?” She pointed to the dust. “No arc. No sweep. Nothing opened over the floor.” Mercer’s mouth thinned. “You’ve got a vanishing act now.” “I’ve got an entry point you missed.” She held the compass up beside the wall. The needle quivered, then pinned itself at the centre tile, directly over a torn poster for a long dead comedy night. Halim moved closer with his camera. “You want this documented?” “I want every inch of this wall photographed, measured and dusted. Then lift the poster.” Mercer rapped the tile with his knuckle. “Solid.” Quinn took his pen from his notebook without asking and tapped three places. Tick. Tick. Tock. The centre returned a duller note. Mercer held out his hand for the pen. She gave it back. “Cavity,” she said. He swore under his breath. Halim peeled the poster from the tile in careful strips. Old glue gave way with a papery sigh. Underneath, someone had scratched a ring of symbols into the glaze. They matched the tiny marks etched around the compass face. Not decorative. Functional. Deliberate. Mercer stared at them. “What language is that?” Quinn did not answer at once. Three years fell through her like a dropped stone, a derelict flat in Stepney, Morris on one knee by a scorched bedroom floor, tracing a mark that looked harmless until the room had changed shape around them. He had laughed at it then. Six hours later, he had vanished into a stairwell that had not existed on the plans. She blinked the memory away. “Bag every loose paper on this platform,” she said. “Every token, every label, every scrap. No one leaves with souvenirs.” Mercer looked at her, sharper now. “You’ve seen this before.” “I’ve seen symbols used to hide routes.” “That sounds mad.” “It sounds useful.” A constable at the stairwell called down. “Ma’am, press are gathering at street level. Uniform wants a line.” Mercer answered without looking away from the wall. “Tell them trespass and one fatality. Keep them hungry.” Quinn crouched by Weller again. His right hand had clenched after death. She prised the fingers open. White plaster dust packed the creases of his palm. Under his nails sat green corrosion, the same shade as the compass hinge. He had held the compass hard before he died. In the centre of his palm a half-moon bruise darkened the skin, the mark a token had left when someone pressed it into his hand. He had known where he was going. He had reached it. Then something had turned on him. Mercer knelt across from her. “You’ve got something.” “He came through that wall, not the stairs. Clean soles. Plaster dust. Fresh grout. He held the compass as a guide.” Mercer nodded towards the wound. “And someone on the other side slit his throat and dumped him here.” Quinn shook her head. “No dump job. Look at the blood.” She stood and traced the dark spray on the tiles with two fingers in the air. “The burst starts high and falls left. If he died where he lies, his body would block half of it. It doesn’t. He bled upright, closer to the wall. Then he dropped forward, and someone rolled him onto his side.” “Why?” “To show the wound. To hide the wall.” Mercer rubbed his mouth with the back of his hand. “That is either brilliant or a long walk off the map.” Quinn pointed to the nearest stall. A handwritten tag hung from an empty velvet stand. VEIL COMPASS SHADE WORK POINTS TRUE WHERE MAPS FAIL Mercer read it. “Shade work?” “Someone sold guides to hidden places from this platform. Weller bought one. He followed it here. The traders cleared out, but not before he died.” “And the chained gate?” “Stage dressing. If the wall is the real route, the gate tells us a lie. It turns this into a locked room.” Mercer rose. “All right. We break it.” “Carefully.” He waved two uniforms over with a pry bar and a small hammer. Their boots thudded on old concrete. Around them the station held its breath. Candle stubs shone like blind eyes. Somewhere in the tunnel, water dripped with maddening patience. Halim took one more photograph and stepped back. “Ready.” Quinn put the compass in her palm and felt the needle jerk against the glass. Harder now. Hungry. The uniforms set the pry bar at the seam between two tiles. Mercer nodded. “Go.” Metal bit grout. The first push cracked plaster with a dry snap. White dust spilled down the wall. The second push drove deeper. Something answered from the other side. Not an echo. A blow. The wall shuddered. Tiles clicked against one another. Dust rained over the body and the platform. One of the uniforms jumped back. “Sir?” Mercer snatched the pry bar himself. “Again.” He rammed it into the seam. The hollow behind the wall gave with a groan. A black line split from floor to shoulder height. Cold air punched through it, sharp enough to sting the teeth. The compass needle spun in Quinn’s hand so fast it blurred. Then a fist burst through the crack, pale, shaking, caked in plaster. A woman’s voice tore through the gap. “Move!” The false wall blew inward. Tiles shattered across the platform. A small woman with curly red hair and round glasses stumbled out in a shower of dust, a worn leather satchel locked to her chest. She hit the ground hard, rolled, and looked straight at Quinn with wild green eyes. “Shut it,” she gasped. “Shut it now.” Behind her, something slammed the broken opening from the dark.
