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.” Detective Harlow Quinn ducked under the bent tube barrier and stopped dead at the edge of the platform. A white-gloved scene officer had his hand suspended above a line of chalk marks, his face gone pale under the harsh spill of portable lamps. Quinn’s gaze tracked past him, over the disused tiles, over the old advertising frames with their torn paper skins, and fixed on the body laid out beside the track. A man in a charcoal suit. Bare feet. No socks. No shoes within reach. That alone was enough to prick at her temper. She crouched, leather watch creaking on her wrist, and took in the rest in one sweep. Blood had pooled under the head, thick and black where it had sunk into grime between the platform slabs. Not much of it, though. Too little for the amount of damage to the temple. A brass ticket punch lay beside the left hand. A commuter’s relic, absurd and polished clean, its handle still carrying a slick sheen. “Sergeant Mallory told me you’d want the scene frozen,” the scene officer said. “I want it accurate.” A voice behind her cut through the station’s stale stink of rust and dust. “Accurate would be a start, Quinn. Sensational tends to come later.” Detective Harlow Quinn stood without turning. She already knew the cadence. She turned anyway. Detective Quinn. No, the title didn’t need the rank. Harlow Quinn in a dark coat, closely cropped hair, sharp jaw set like stone. Her partner from the Met’s supernatural liaison unit, or as close as she came to a partner these days. DS Mallory Graves had the kind of face that always looked one step away from a smirk, but tonight her mouth had flattened into a thin line. She stood at the end of the platform with a torch in one hand and a paper evidence bag in the other. Mallory held up the bag. “Found this on the stairwell. Bone token.” Quinn took the bag, tilted it against the light. A small, yellowed piece of carved bone with a hole punched through the top. The surface carried a greasy thumbprint and a spiral cut into the centre, crude and deliberate. “Where?” “Top landing. In the drain grate.” “Planted.” Mallory gave a soft huff. “Or dropped. There’s a difference.” “Not here.” Quinn stepped back towards the corpse, careful not to cross the cordon. The platform curved away into darkness at both ends, the station’s broken signage hanging above them like snapped teeth. Camden’s hidden underbelly had always attracted strays, thieves and liars in equal measure. Now the place served as a slaughter room for whatever had dragged a banker, broker, or black-market buyer down here and left him with his shoes missing. Or for whoever wanted the body found. Quinn’s eyes narrowed at the victim’s right hand. The fingernails were clean. Not a trace of dirt beneath them. No defensive skin splits, no bruised knuckles. Yet the sleeve of the suit jacket had a crescent tear at the cuff, fibres peeled back as if snagged hard on metal. She leaned closer, careful, and caught the scent. Copper, yes. But underneath it, a sharp herbal tang. “Something burned him.” Mallory looked over the tape. “The pathologist can tell us more.” “No need. Burn mark here.” Quinn pointed to the inside of the left wrist, where a faint crescent blister had formed in the skin, pale around the edges. “Not a cigarette. Not electricity. Cautery. Clean, narrow, deliberate.” Mallory’s eyebrows climbed. “You think someone tied him down?” Quinn gave the body a look that passed for contempt. “If they had, his shoes wouldn’t be missing.” A flash of annoyance crossed Mallory’s face. “You’re in one of those moods.” “I’m in a working mood.” “Good. Because I’ve got a theory and I’d like at least one person in this station to indulge it.” Quinn reached into her coat and withdrew a pair of gloves. “Indulge away.” Mallory stepped closer but stayed outside the line. She pointed at the body with the torch. “No visible struggle on the platform. No drag marks worth mentioning. One blow to the head, he goes down, hits the edge, dead or dying. Then someone removes the shoes, pockets the wallet, and walks out. Simple robbery.” Quinn slipped on her gloves and lowered herself to the floor beside the corpse. “Simple robbery leaves a watch.” “It can.” “It can’t, not when the victim has an expensive wristwatch and the hands remain untouched.” Mallory’s mouth twitched. “You say that like you’ve already nicked a watchmaker.” Quinn ignored it. She reached for the victim’s left wrist without touching skin and angled the portable lamp. The watch strap had left a deeper impression than it should have. The leather had been fastened too tightly, then loosened recently. The buckle sat on the inside rather than the outside. “Someone took this off after death,” Quinn said. “Or after he was already unconscious.” “Which still fits robbery.” “No.” She tapped the air over the wrist. “See the abrasion? The buckle rubbed this way. That means the watch was worn on the wrong wrist first.” Mallory stared. “And that matters because…” “Because the man was right-handed.” Quinn’s gaze travelled to the body’s dominant side. The right hand lay open, the thumb curled slightly inward. “The abrasion on the left wrist shows habitual use. But the buckle was reversed. Either he wore it there under duress, or someone put it on for him.” Mallory looked from the wrist to Quinn’s face and back again. “That’s a leap.” “It’s a deduction.” “From a watch?” “From a lie disguised as one.” Quinn turned her attention to the shoes. Not there. Not just absent, but cut away. The trouser hems ended in neat, jagged lines. She touched the fabric at the right ankle, where the frayed fibres gleamed under the light. “Knife.” Mallory crouched beside her. “You think they cut him out of his own shoes?” “They cut the shoes off him. Fast.” Quinn glanced up the platform. “And they did it before the blood dried. See the pattern at the heel stain? Pressure print. He stood here after injury, then moved. If he’d been dragged, we’d see a smear.” Mallory crossed her arms. “So he walked.” “Barefoot.” “Still robbery.” Quinn rose in one smooth motion and faced her. “To steal shoes from a corpse in a sealed underground station, after a precise kill, on a platform that has no active public access and one entry controlled by a bone token? That’s not robbery. That’s theatre.” The torch beam in Mallory’s hand wavered a fraction. She recovered it quickly. “Controlled by a bone token,” she repeated. “You sound amused.” “I’m not.” They stood in the old station’s silence, broken only by the distant hiss of a generator and the scrape of gloves as an officer shifted behind the tape. Quinn turned away before Mallory could read more off her face. The staircase leading down from street level had been the obvious choke point. Quinn climbed two steps, then stopped. One of the treads had a nick in the edge, a fresh white scrape against the rusted metal frame. She bent and examined it. Tiny flakes of verdigris clung to the scrape. Brass. Not from the station. From a compass casing, perhaps, or a lock plate. The particles had collected in the seam where the stair met the wall. “Someone came down in a hurry,” she said. “Or left one.” Mallory followed her line of sight. “You think our killer dropped something.” “Or checked direction.” “For what?” Quinn didn’t answer straight away. She pressed two fingers to the scrape, then held them under the lamp. Green dust dusted her glove like old paint. “Rift residue.” Mallory’s expression shifted. Not fear, not yet. A professional hardening around the eyes. “You’re certain?” “Smell it.” Mallory did, and her nose wrinkled. “Metal and vinegar.” “Exactly.” Quinn climbed another step and peered into the grate at the landing. Between the rust bars she spotted a thread caught on the metal, black wool snagged against a bent edge. She tugged it free with tweezers from her kit. Not wool. Velvet. A thin sliver of dark fabric, the kind worn on a coat lining or glove cuff. She held it to the light and found a crescent of wax on one side, stamped with a partial seal. Mallory leaned in. “What’s that?” “An invitation, if the owner reads the right circles. Or a blindfold, if they don’t.” “Quinn.” “Someone wanted access to the Market.” Mallory gave her a sideways look. “The Veil Market?” “Where else do you buy bone tokens and murder with etiquette?” For the first time, Mallory let out a brief, humourless laugh. “You do realise how that sounds.” “I do. It’s still the answer.” Quinn descended to the platform again and crossed to the far end where the old staff door had been welded shut years ago. The metal bulged inward at knee height. She knelt and ran her gloved fingers along the seam. A faint powder coated the hinge. Grey, chalky, bitter to the nose. She snapped her fingers once. “See this?” Mallory bent. “Ash?” “Salt ash. Burnt rosemary. Used for warding, not cleaning.” Mallory straightened. “So now the dead banker carried ritual supplies?” “Or his killer did.” Quinn stood and moved back to the body. The officers watched her in that fixed, resentful way civilians reserved for people who made sense of things too quickly. She ignored them and checked the corpse’s coat pockets, lifting the lapel with care. The inner breast pocket had a torn lining. Empty. There, stitched into the fabric, a hidden slit had been cut open from the inside. “Wallet first,” Mallory said. “Then shoes. Then the watch.” “Then the coat,” Quinn replied. Mallory frowned. “What coat?” Quinn pinched the torn pocket lining between two fingers and turned it out enough for Mallory to see. A fine residue fell into the folds of the dead man’s shirt. Bone dust. Mallory went still. “That came from the pocket?” “Yes.” “You’re saying he carried a bone token.” “I’m saying he carried something cut from bone, and someone searched him for it after he died.” Mallory’s face hardened. “Then why take his shoes?” Quinn looked at the bare feet, at the neat absence where leather should have been. “Because shoes carry you out. Bare feet keep you from being followed.” The words sat between them. One of the officers swallowed audibly. A sharp crack echoed from the far tunnel. Every head turned. Quinn was already moving. “Lights.” Mallory shouted it as she broke towards the end of the platform, torch swinging. Quinn caught the glint before the others did, a small brass circle rolling once across the tiles and stopping against a rusted drain cover. A compass. Her pulse ticked once, hard. The casing flashed green under the lamps, its surface patinated with verdigris. Protective sigils etched the face in a tight ring. The needle jerked, spun, then locked towards the black mouth of the tunnel leading east, where the old line vanished into bricked darkness. Mallory drew a breath. “That yours?” Quinn was already crouching for it. “No.” The compass twitched in her hand the moment she lifted it, as if something beneath the station had awakened and noticed her touch. The needle snapped against the glass, then spun hard again, not towards the tunnel this time but downward, towards the tracks under the platform. A tremor ran through the rail bed. Dust fell from the ceiling in a thin grey curtain. One of the scene officers shouted, “Everyone back!” Quinn looked down between the sleepers. Something moved there. Not a rat. Not water. A seam of darkness, narrow as a knife blade, opened under the platform edge and bled cold air up through the rails. The portable lamps flickered. The brass compass in her palm gave a violent shudder, the needle hammering so fast it blurred. Mallory’s voice cut sharp through the rising panic. “Quinn, what have you got?” Quinn stared at the crack widening under the track. “Not a robbery,” she said. The platform groaned. And from the dark slit beneath the station, a hand reached up, bare and white, and closed around the rail.
