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>

"Step away from the chalk." Harlow slipped between two uniforms and the jagged circle painted on the floor, gloved hand up, palm steady. The body lay inside it, face turned towards the track, eyes half open as if he tried to watch the place where no train would ever come. "Nobody's touched him," a constable said. "We marked the perimeter after SOCO finished their first pass." "Good," Harlow said. She crouched. The circle wasn't chalk. Her fingertips found grit and a reminder in her nose, resin and something acrid under the metallic tang. Not candle ash. Black salt. Ground obsidian. She straightened, felt her knee crack, and looked at the man in the circle. DS Owen Patel padded over, balancing a tablet and a takeout coffee like a waiter who'd lost a bet. His tie had slid sideways. He nudged it back into line with one finger, then took in Harlow's stance and the circle and the blank rails beyond. "Spooky art installation," he said. "Popular with our Camden set. Meant to keep bad vibes out. Kid tripped in the dark, split his head, bled out before his mates found a signal." "Popular with your Camden set?" Harlow kept her gaze on the dead man's hands. Clean palms. Nails clipped. No residue under them, no defensive injuries. The back of the skull had a crescent split, yes, not messy enough for a heavy fall on a random edge, too neat, too placed. She looked at the floor outside the circle. Scuffs. The mark of one knee. Someone had leaned in here. A trainer drag to the left. The smudge of soot on skin at the right wrist. She clocked each detail the way she always had, like ticks of her old leather watch. "Or some wannabe cult," Patel went on. "Look at those symbols. Netflix taught them this one last winter. We found a ring of kids in Highgate with goat skulls made from papier-mâché and Pimm's. They swore they could invoice Satan." Harlow bent closer to the dead man's face. Late twenties. No ID out yet. The cheeks had a hint of stubble. She sniffed, ignored Patel's coffee, and picked up the faint trace of frankincense under the damp and dust. Frankincense, and... copper. The blood smell hit like a slapped lip. Recent, but the dryness at the edges told its own time. She didn't look at her watch. She didn't need to. She fixed her eyes on the way the spill of blood would have tracked if he'd fallen. It would have spread towards the slight slope near the edge of the platform. Instead, the clot thickened towards the centre of the circle. Someone had stopped the natural run with the ring itself, hard salt, not a chalk line. They'd poured it fast. Some grains still showed sharp edges, not softened with time or damp. "Looks like a bump and a slow leak," Patel said. "These places flood. Slippery tiles, bad luck, too much ketamine. He crawled in there because he thought the circle meant safety. People are like that." "People are like that," Harlow said. He looked pleased she agreed. "We pull CCTV from above, we find whoever he was with. They are looking at negligence, public nuisance, and a caution for trespassing. Maybe possession. Done by lunch." Harlow stepped past him and let her eyes move beyond the pool of lamps. They'd set floodlights up along the platform and strung cable back to a generator that coughed outside the stairwell. The defunct station had been trapped down here like a fly under a glass, adverts peeling, tiles chipped, air heavy. A piece of paper near the far wall fluttered in the breath of the generator. She traced the edges of the circle with her boot. The arrangement of symbols along it had the right alphabet but the wrong grammar. Like a tourist memorising a prayer from the back of a menu. Yet one sigil at twelve o'clock wasn't wrong. It sat crisp, careful, etched with a nail and filled with ash, not just drawn. Protective. Old. She paused, let the lines form in her head where she didn't have to say them out loud. A uniform edged forward. "We bagged something from his coat, ma'am." "Show me." The constable held out a clear evidence bag. Inside lay a small brass compass. It wasn't regulation Boy Scout kit. The casing wore a skin of greenish patina like lichen. The face gleamed behind scuffed glass, etched not with degrees but with sigils so fine they seemed to spin even while still. The needle jittered, a small bird trapped in a jar, and settled on nothing that resembled north. Patel snorted. "Gimmick. Camden stalls sell a thousand of those. Tell you your aura's off, need cleansing." Harlow weighed it in her palm through the plastic. It had the comfortable heft of something made by hand, not stamped. "Where did you find it." "Inside pocket," the constable said. "Left." "Anything else." "Phone, no battery. Wallet with thirty quid, no ID. This weird token thing. Bone, I think." He held out a second bag. A small disc of bone with a drilled hole and faint striations sat inside, oily from fingers. The edges were worn smooth. It had a simple carved design that could have been a letter, or a mark used long enough to forget it started as anything else. Harlow breathed out. The token felt like a whisper of a place she didn't admit to knowing. Old cases left grit in your lungs. "Seal that. Both of them." Patel watched her too carefully. "You look like you have a story for this." "I have a dead man," Harlow said. "You have a long list of assumptions." "Enemies of progress," he said. "All right. Killjoy me. What am I missing." She set the compass down on her knee, still in its bag. The needle juddered, then swung. Not to the turnout sign, not to the stair. It pointed at the tiled wall opposite the platform, straight at a patch of grime and cracked cream that made nothing. Her skin prickled. The generator thumped. The needle shivered and stayed there, stubborn as a held breath. "Your north," she said, quiet. "Coincidence," Patel said. "Magnet in the wall." "There is no magnet in the wall." "We are in a station." "A station with its power cut a decade ago. Nothing hums here except that old machine upstairs and your nerves." She stood and walked to the edge of the platform. The track pit gaped, ballast like chewed gravel. She crouched, tested one sleeper with her gloved fingertips. Dry. Dusty. She leaned out and looked at the rail chairs. Someone had scraped at one with something sharp. Fine shavings lay below in a neat scatter. She tasted an edge to the air there, a bite at the back of the tongue, like licking a battery as a kid because someone dared you. Patel leaned beside her, less comfortable near the drop. "You and Morris used to get like this." She didn't look at him. "Morris observed. He didn't get like anything." He cleared his throat, looked away, and took a sip he didn't want. "So, your wall." She stood, stepped back, and got the light onto the tiles. The white had gone grey with age, but under the soot she found a set of faint scratches that didn't belong to the last century's tiled maintenance. Fresh. Narrow. Someone had prised at mortar. She drew a square in the air with one finger to fix the shape for herself. Not a ticket door. Too small. An access hatch, but not from a railway manual. "You saw a cartoon, didn't you," Patel said. "Secret panels. Inspector Harlow and the Ghost of Platform Nine and a Half." "Who brought the chalk." "Kid with an online order." "The circle went down after the body," she said. She pointed at the crisp edge where the salt met the dried blood. "You see that. It acts like a dam. The reservoir hits a wall. Whoever put him there made that line to hold the flow. And the blow to the head, look at the bruising, shallow, no spatter. It settled. Someone pressed him to the floor but didn't smash him there." He squinted. "Pressed him." "Held him still. He didn't fight. He didn't expect it. He wasn't alone." "We can agree he wasn't alone. How else does he end up down here." Harlow looked at his shoes, then at the dead man's. The soles were too clean. Dust had puffed up when uniforms first arrived, their prints dulling to grey. His lay crisp. The edges of his tread still held factory cuts. "He didn't walk in on his own. His soles don't hold this place. Someone carried him or he came a different way and in a hurry. No grit ground into the rubber. No soot lift on the sides. And there is no sign a group dragged him down the stairs. We would see it in the smear marks and the railings. They went a way that didn't involve our station." "Fairies then," Patel said. His smile didn't reach his eyes. Harlow flicked the evidence bag. The needle swung and snapped back to the same tile. "Find charm, find door." "You sound like my grandmother," he said. "I sound like a detective." She stepped away from the body and paced the platform to the far end, skirting the puddles where the roof had wept in winter. Old crisp packets had gone to rags. The posters showed toothpaste and a new estate in Croydon that never opened. She pushed her palm along the tiles near the spot the compass loved. The mortar felt sandy and new in a few centimetres of line, as if someone had worked at it with a small tool and patched it in haste. The scratch marks made a half frame. At about chest height, a tile bore a hairline crack, straight, as if scored rather than aged. "SOCO photographed that," Patel said. He scrolled his tablet with a frown. "They flagged vandalism, not unusual." "Look for residue on the edges of that crack." "Waste of time." "Look for it," Harlow said. "Unless you want another embarrassed meeting where you explain to Silver why our dead man had a bone disc from a market that doesn't exist." He stilled. "What market." "You know it if you think you don't," she said. "People find it when they deserve to be relieved of their money. Or their tongue." "You have a colourful file cabinet in your head," he said. He clicked his tongue and waved a tech over. "Swab that crack. Both sides. And the grout." The tech nodded, snapped a swab into its sleeve, and got to work. Harlow watched his hands. He moved with that careful boredom good mortuaries bred. He reached the crack, hesitated, peered, and then held up a brow he probably did in mirrors. He dipped, then pulled the swab back and looked at the cotton. It had gone black. "What is it." Patel always asked like it would be stupid to be surprised. "Residue," the tech said. "Soot, looks like, but... it has a sheen. Like metal worked too hot. Smells sweet. Not tar." Patel sniffed, flinched. "That is not sweet." "You have cheap cologne," Harlow said. "It is sweet. And wrong. Bag that." The tech nod, bagged, labelled. Harlow returned to the body. She stared at the pattern of symbols around the circle again, let the wrong ones fade, and pinned the one done with care. It had been set opposite where the compass pointed. It had been carved where someone could reach without leaning, hand at a comfortable angle. Someone had known that one at least, known where it ought to live. Meaning bled with practice. If the rest were theatre, this was a lock. "Your artist," she said, "knew one thing and hid it under rubbish." "Lock," Patel said. "Door. Ghost. All right, go on then. Suppose there is a door. How did our friend die. Magic bullet." Harlow looked at the back of the skull, at the crescent cut. The edge hadn't chipped like a fall onto concrete might. It had the line of something with give, like wood. The skin at the nape had a three-finger bruise, where someone had pressed down and tilted the head forward. She pressed her own neck under her ponytail and felt where that grip would go. "He knelt for it," she said. "He what." "He knelt to put his head somewhere low," she said. "Look at his knees. No fibres from denim here ground with dust. No abrasions. Someone guided him. Head into a space low enough to bump the crown before the blow. He didn't brace. He bent as if to pass through or to peer into a small opening. Whoever stood behind did the rest." "Why dramatics then," Patel said. "If this is murder, why the dan brown doily." "Because someone needed to cover a door they couldn't fully close," Harlow said. "So they built noise around the signal. The circle. The candles that never dripped here. Your kettle logic men upstairs will argue online about pentagrams while our door sits and hums like a bitten tongue." He scoffed, but his shoulders had inched nearer to hers and the circle both. "Search the pockets again for a card," Harlow said. "A museum pass. A library slip. Anything with a stamp." "You're doing that voice again, Harlow." "Which." "The one you use when you already looked." She said nothing. He waited. She waited longer. He huffed and waved the constable back over. "Run them again," Patel said. "He wants a stamp." "I want a link," Harlow said. "He carried a made object and a permission. He didn't buy that compass at a stall with neon mushrooms and a DJ. Someone gave it to him and told him a story that involved rules. People who believe in rules carry passes." Patel worked his jaw. "You ever consider a counsellor. Grief does odd things." She turned her head very slightly. He coloured. He was kinder than he was clever. She turned back to the tile. The hair on her arms had lifted. The air near the wall sharpened. The generator outside chugged and then coughed, slow as a drunk clearing a throat. "Get away from the wall," she said. Patel laughed. "Oh, for, you cannot call it without a wind machine and a choir." "Step back," she said, quieter. She didn't raise her voice. She never wasted it. He saw her face then, saw she'd filed everything else he hated away into something heavy, and he took two steps back on his own. The tech froze. The uniform looked at his sergeant for a cue, saw none, and shuffled. Harlow moved to the side where the sigil sat carved correct. She placed her palm flat on a nearby tile, not the one with the crack, and closed her eyes long enough to measure the temperature shift. The tile radiated faint warmth the rest of the wall lacked. The warmth had pattern. It pulsed. She opened her eyes. "It is not fair," Patel said. "You always look so reasonable." "Open your ears," she said. He went still. At first all he would have heard was old station breath, the rattle of cable, the far cough of a city dressing itself in its own noise. Then, under it, a thin whine built, insect and half red in the skull. The floodlights nearest the wall brightened, dipped, brightened, a tired blink. The needle in the bag hit the glass with a click. The swabbed crack shivered. Mortar dust whispered down and made the smallest ash-fall on the floor. The symbols around the circle seemed to darken without moving, as if something looked out through them and learned its letters. Patel said something that started as a joke and lived one second with that shape, then died before it arrived. The tech took a slow breath and reached for his radio. It made a burp of static, sulked, and went dead. "Back," Harlow said. She pulled the tech with two fingers at his sleeve. He came easier than she would have guessed. The uniform tried to be brave and chose to be sensible instead. He retreated until his heel hit an old poster rail and stopped. A hairline crack across the tile snapped from a line into a split. It widened the way a mouth opens when it doesn't know how to stop. There was no hinge. There was less sound than there should have been, less crunch. The gap had dark inside it, not the ordinary dark of a maintenance void, more like new ink spread in clear water. Patel grabbed her arm, hard enough to prove he had fingers and bones. He breathed a noise like a caught animal. "Harlow," he said, new voice in his throat where his old ones didn't reach. "Tell me this is a riot shield exercise." The body inside the circle gurgled. Every head snapped that way. The dead man's lips parted. A thread of black liquid crawled from the corner of his mouth, not blood, nothing that clotted. It stretched like treacle and then recoiled with its own mind. His tongue twitched. His eyes rolled in their sockets and fixed on the crack in the wall. The tile finished giving way. Something put a hand through.
