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>

Harlow Quinn caught the young constable before he could step over the threshold. “Don’t touch anything with bare hands.” The constable froze, one polished shoe hovering over the yellow tape. Harlow slid under it, leather watch creaking against her wrist as she straightened. The abandoned Tube station swallowed her in a throat of brick, rust and stale damp. Voices carried oddly along the platform. Somewhere deeper in the dark, metal clinked against metal. A forensic photographer lowered her camera. “Thought you’d want first look, Detective.” “I always want first look.” Harlow took in the scene in one sweep, sharp jaw set, brown eyes moving with military neatness from left to right. “Who let uniform in here?” “No one did,” said a voice from the tunnel mouth. “He came with me.” Eva Kowalski emerged from the gloom with her worn leather satchel pressed against her side, curls frizzed from the journey down and round glasses catching the glare of portable lamps. She tucked a strand of red hair behind her left ear, then stopped when she saw Harlow’s expression. “You called me in after the officers, not before.” “I called you in because the officers thought I’d enjoy a corpse in a place that smells like wet pennies and old electricity.” Eva’s gaze flicked to the tiled wall, to the copper-coloured smear that ran across it in a broad arc. “That’s not blood.” “No?” “It’s iron salts. Split with something alkaline. See the crusting? And the smell.” Eva reached for her satchel, then seemed to remember where she stood and kept her hands on the strap. “Bitter. Like burnt soap.” Harlow followed the line of the smear. It led from the platform edge towards the centre of the station, where a man lay on his back beneath a tarp that the scene tech had peeled away for the first glance. No obvious wounds. No wild blood spray. No slashed throat. Just a pale face, mouth open as if he had been caught mid-breath and then forgotten. “Name?” Harlow asked. “Unknown,” said the constable. “He had to have one before he became a puzzle.” The constable flushed. Harlow ignored him and crouched near the body. The dead man wore a dark coat with a velvet collar, expensive boots, and gloves tucked into one pocket. Not a dealer’s look, unless he liked vanity with his vice. The station floor around him had a scatter of grit, broken chalk, and three small brass coins stamped with a sigil she did not know. Eva’s head tilted. “Those aren’t coins.” Harlow glanced up. “What are they, then?” “Tokens. Or wards. Old work.” Eva shifted closer, careful not to cross the marker line. “I’ve seen that stamp in restricted catalogues. Pre-war European, mixed with something South Asian. Ugly blend. Purpose built, not decorative.” “Purpose.” “To keep something in. Or out.” Harlow looked past the body, past the tarp, to the far side of the platform. A line of lamp light revealed a ticket booth with its glass cracked like a spider web. Behind it stood a row of hooks, and from one hook hung a bone-white disc the size of a saucer. A token. Not a coin. Not brass. Bone, drilled with a hole, threaded with black cord. The market’s entry requirement. Her eyes narrowed. “Where did you find the token?” The constable pointed to the platform edge. “Near the body.” “That’s not where it was found.” Eva stepped in before the man could answer. “If the Market used this station, the token would sit at the entrance. You’d present it before entry. The body’s central, so someone moved him.” Harlow rose in one clean motion and moved to the platform edge. She crouched and touched the grit without disturbing it, then lifted her fingers to the lamp. “Not moved,” she said. “Dragged.” The photographer frowned. “From where?” “From down there.” She pointed to the black mouth of the tunnel. The line of grit thinned there, but on the lip she saw it, a shallow furrow in the dust, too straight to be an accidental skid and too narrow to belong to a corpse in boots. Something light had gone in first. Something heavy had come after. Harlow stood and stared into the tunnel. The air changed there. Not temperature, not quite. Pressure. A suggestion that the dark had weight. Eva noticed her face. “You see it too.” “I see a tunnel.” “You see the seam.” Harlow gave her a look. “Don’t start talking like a sermon in a crypt.” Eva gave a tight smile and reached into her satchel. She drew out a small brass compass, its casing green with verdigris, face etched with protective sigils so fine they looked like scratches until the light caught them. She opened it in her palm. The needle spun once. Then it jerked, settled, and pointed straight into the tunnel. Harlow’s gaze sharpened. “That yours?” “Not mine. Borrowed from the archives. If it is where I think it is, I want it back before the curator notices.” “A very casual crime at a very unusual scene.” Eva snapped the compass shut. “You called me for unusual.” Harlow did not answer. She stepped to the body again and looked at the dead man’s hands. Fingernails neat. No defensive tears. No dirt under the tips. On the left ring finger she found a faint silver line, as if a band had sat there until recently and slipped off or been removed. “Ring?” “Not on him when we bagged him,” said the forensic photographer. “Of course not.” Harlow’s eyes moved over the coat seams, the cuffs, the inside lining where a tailor would hide a label. “Search the pockets.” A gloved hand obeyed. Out came a folded note, a fountain pen, a railway map, and a length of black ribbon stiffened with something dry. Eva saw the ribbon and went pale in the way only scholars did when a library item turned wrong in front of them. “That’s binding thread.” Harlow took the note. The paper was thick, watermarked, folded twice. No name on the front. She opened it and read the few scrawled words. DELIVER TO THE CLOCKWORK CHAPEL BEFORE THE MARKET MOVES DO NOT TRUST THE DETECTIVE “Charming,” Harlow said. Eva leaned in. “Show me.” She handed it over. Eva read once, then again, lips pressing tight. “Clockwork Chapel is not a chapel. It’s an old term in warding texts for a temporary ritual site. People used abandoned places where power pooled. London had hundreds of them.” “This one had a market.” “Yes. Markets are excellent camouflage.” The constable cleared his throat. “We’ve got statements from two traders and one cleaner. They all say the victim came in with a woman.” Harlow looked up. “A woman.” “Dark coat. Veil over her face. They couldn’t agree on height.” “And no one stopped her.” The constable glanced at Eva, then back at Harlow. “They said she paid with a bone token.” Eva’s fingers tightened on the strap of her satchel. “That narrows it down to a few dozen regulars, and most of them would not carry a corpse through a public route.” “Not a corpse.” Harlow’s eyes returned to the drag marks. “A body. Dead after entry. Someone wanted him found here, not buried elsewhere.” Eva’s brows drew together. “You’re saying staging.” “I’m saying someone with access knew exactly how to make this look like a market killing.” “Which it was.” Harlow turned on her. “Was it?” Eva opened her mouth, then shut it. She hated being cornered and Harlow knew it. That was part of the reason she’d called her in. The dead man’s cuff had ridden up during the examination, revealing a pale wrist marked with a thin crescent bruise. Harlow hooked a finger under the sleeve and pulled it higher. Beneath the bruise, pressed into the skin, sat a tiny puncture wound. “Needle?” the constable asked. Harlow shook her head. “Too neat.” Eva crouched opposite her, careful and poised. “Not a needle. A ritual spike. See the ring of inflammation? The wound held a charge.” “Speak plain.” “It means something was drawn out of him.” Harlow stared at the puncture, then at the brass tokens on the floor, then at the note. “Not killed by force. Drained.” “That would fit the pallor,” Eva said. “And the bloodless look. But no one drains a man here and leaves his body on display unless they want the market to panic.” “Or unless they want us here.” The station seemed to tighten around that thought. A train line groaned somewhere beyond the walls, a low, distant vibration that went through Harlow’s boots and into her teeth. She looked towards the tunnel again. At the far edge of the platform, near the old sign for the westbound line, a shape had not been there moments before. It rested against the tile wall, a bundle of black cloth tied with cord. “Was that there?” she asked. The photographer turned. “No.” “No one moved?” Harlow asked. “Not from this side.” Eva stood, all her scholar’s caution gone thin. “Don’t touch it.” Harlow was already walking. She reached the bundle in four quick strides and cut the cord with the edge of her glove. Inside lay a severed hand, pale and waxen, ring finger bare. A signet ring sat in the palm, stamped with a sigil she recognised from files she had no business knowing existed. Harlow’s mouth tightened. Eva saw the ring too. “That’s not market trade.” “No.” “That belonged to someone who knew the routes.” Harlow lifted the hand by the wrist and turned it. The palm held a smear of black grit and one tiny crescent of green verdigris. She looked back at the body on the platform. The dead man’s left hand. No ring. No matching wound on the wrist. He had not lost the hand here. Someone had brought the hand here separately. Harlow glanced at the station entrance, at the line of officers, at the unsteady focus of the photographers. “Who found him?” The constable blinked. “One of the traders raised the alarm. Said he collapsed near the stall row.” “Which trader?” “Didn’t give a name. Veiled up. Kept to the shadows.” Eva’s voice sharpened. “Did she have gloves?” The constable hesitated. “Yes.” “Silk?” He frowned. “I think so.” Harlow looked at Eva. “You know something.” “I know a lot of people in the restricted archives lie through their teeth. They lie about provenance, lie about access, lie about what they saw and when.” Eva’s fingers slipped to the edge of her satchel. “A silk glove leaves a different trace on binding thread than leather. It doesn’t snag. It slides.” Harlow turned back to the body, then to the note. “Then our veiled woman was careful.” “Careful people survive in that market,” Eva said. “The careless get robbed or sold.” “Or planted.” Eva’s face changed by a shade. “You think the dead man was planted.” “I think someone wanted this scene interpreted one way.” “By who?” Harlow’s eyes went to the wall of the station where the old route map hung, water damaged and half torn away. On the glass, reflected behind the constables and the lamps, she saw movement. Not on the platform. In the tunnel. A pale shape slid past the black mouth, just out of the light, too tall for a man and too thin for comfort. It moved with a limber, patient glide, as if it knew the station better than the people standing in it. Harlow did not blink. The figure stopped. A sliver of face appeared from the dark, smooth and grey as candle ash, eyes catching the lamp in small wet points. The compass in Eva’s hand snapped open on its own. The needle spun hard, then flew to the tunnel. “Quinn,” Eva said, and for once her voice had lost all scholar’s steadiness, “that isn’t on any archive shelf.” The figure in the tunnel lifted one long hand, and every brass token on the platform began to rattle at once.
