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>

The corpse moved as Quinn
stepped under the police tape.
Its right hand slipped from
the butcher’s block and struck the tiles with a wet slap. One of the scene examiners recoiled, knocking a numbered evidence marker beneath a stall. “Christ.” “Dead men still obey gravity.”
Detective Harlow Quinn caught the
wrist before the fingers reached a dark pool beneath the block.
The skin felt cold and
waxed, but the joints retained a trace of softness. Dead for hours, not days.
She returned the arm to
the dead man’s chest. “Who moved him?” “No one.”
Detective Sergeant Callum Reed watched
her from the platform edge.
His disposable white suit strained
across his shoulders. Beneath it, the toes of his polished shoes had turned grey with dust from the track bed. “The hand stayed put until you arrived.” “Convenient.” “For the paperwork, I’ll put cause of movement as intimidation.” Quinn straightened. At five foot nine, she could survey most of the scene without shifting position.
Her closely cropped salt-and-pepper hair
left nothing to fall into her eyes, and her sharp jaw tightened as she counted the people on the platform. Two scene examiners. One photographer. Reed. A constable guarding the tunnel.
A civilian woman behind the
tape, small, red-haired, round glasses catching the harsh work lamps. Six living. One dead. Too many footprints.
The abandoned station lay beneath
Camden, beyond a service door that Transport for London insisted opened onto a sealed ventilation shaft. Beyond that door, a spiral stair descended through brick slick with mineral bloom.
The stairs ended at an
old Underground platform absent from every current map.
Someone had filled it with
market stalls. Crooked wooden booths crowded the cream tiles.
Glass jars held teeth, feathers
and finger bones. Copper cages hung from hooks, their doors open.
A green liquid crawled around
the inside of a cracked bottle
as if searching for a way out
.
Incense, mould and old blood
clogged the air. Yet the vendors had vanished.
Only the dead man remained
at his stall. “How did uniforms find this place?” “Anonymous call from a public box on Kentish Town Road.” “Those still exist?” “One does. Caller gave directions, including the warning about the third stair.” Quinn glanced towards the staircase. “What warning?” “Don’t step on it.” “And?” “PC Benton stepped on it.”
A stretcher waited beside the
tunnel entrance, holding a constable beneath a silver thermal blanket.
His face had taken on
the grey cast of old candle wax.
He stared at his boots
and mouthed numbers without sound. Quinn checked her worn leather
watch
. “What happened?” “He says the stair bit him.” “Did it?” Reed’s mouth twitched. “Marks say yes.” Quinn crossed to the corpse.
Her movements carried the precision
of drill, each step placed, each glance
measured
. Eighteen years in the Metropolitan Police had taught her that a crime scene rewarded discipline and punished appetite. Most investigators saw the wound first. The clever ones saw what surrounded it. The dead man lay on a scarred black wooden butcher’s block.
He appeared to be in
his late fifties, with a narrow face, silver hair and a beard clipped close to his jaw. Someone had cut his throat from left to right. A thick lake of blood covered the block and dripped between the floor tiles. Reed crouched opposite her. “Robbery gone wrong. Strange place, strange trade, ordinary motive.” “What was taken?” “Whatever he sold. Stall’s empty.” Quinn looked at the shelves behind him. Dust marked several circular spaces where jars or bottles had stood. A clean rectangle suggested the recent removal of a box. Reed’s interpretation had shape. It lacked
weight
. “The other stalls have stock.” “The killer robbed this one.” “And left the rings.” The corpse wore three rings, a gold wedding band and two heavy silver signets. A
watch
chain crossed his waistcoat. A fat wallet remained inside his coat. Reed lifted his palms. “Targeted goods, then. Drugs. Documents. Something worth killing over.” “His pockets?” “Wallet, railway ticket from 1998, three human molars, museum receipt, bone disc. No identification.” Quinn’s gaze moved to the red-haired woman behind the tape.
She hugged a worn leather
satchel to her ribs. Books had warped its shape over years of use. Freckles stood out against her drained complexion. “The receipt brought her here?” “Request slip from the British Museum restricted archives. Signed Eva Kowalski.” The woman tucked a curl behind her left ear. Quinn returned to the body. “Blood pattern?” “Throat opened while he lay on the block. No cast-off on the walls. No arterial spray, but the cut severed both carotids.” “Which means?” “Low blood pressure. Drugged first.” “Or dead first.” Reed studied the wound again. Quinn bent close enough to smell iron, incense and something sweet beneath both. Almonds, but not quite. The cut gaped above the shirt collar. Blood had soaked the wood beneath the neck, yet the white collar remained clean along its folded edge.
She took a torch from
her pocket and cast the beam across the wound. A pale waxy film coated the exposed tissue. “Look.” “I am.” “Look at the lower edge.” Reed leaned closer. “No bruising.” “No swelling. No living response. Someone cut him after death.” “Fine. They killed him elsewhere, then dressed the scene.” “Carried a corpse down that staircase without touching the dust?” Reed turned towards the route from the service entrance. Grey iron grit coated every shoe and disposable cover at the scene. The victim’s black leather boots shone beneath the block. No grit. No scuffs. No blood. Reed frowned. “Someone cleaned them.” “Why?” “To confuse us.” “That phrase should embarrass you.” Quinn lowered herself until her eyes
aligned
with the floor. Blood had spread into the shallow grooves between the old tiles. Three sets of prints crossed it. The scene examiner’s overshoes had left broad tread marks near the edge. Reed’s prints skirted the pool. A smaller pair led from the platform edge towards the corpse. None led away. “There’s your killer.” Reed pointed at the smaller tracks. “Size five, narrow sole. Our museum scholar wears size five trainers with a matching tread.” Quinn looked at Eva’s white trainers. The soles carried grey iron dust. “Did you seize them?” “Photographed and covered.” “Why is she still wearing them?” “Budget cuts.” Quinn crouched over the bloody impressions. Each print held an even, solid colour from heel to toe. No feathering at the edge. No pressure shift. No shallow patch beneath the arch. “Someone stamped these with a shoe held in their hand.” Reed came around the block. “That’s a reach.” “People walk through their feet. Weight rolls from heel to ball, then leaves through the toes. These landed flat. Same pressure, same angle, same depth.”
She pointed to the final
print, inches from the butcher’s block. “And our killer stopped here without turning, then vanished.” “Could have climbed onto the block.” “No marks on the wood except the corpse’s blood.” “Jumped over it.” “Into the shelves?” Reed looked behind the stall. A dense film of dust covered the floor without a single break. Quinn stood. “Bring Kowalski over.” The constable lifted the tape. Eva stepped beneath it with care, keeping her satchel pressed to her side.
Her curly red hair had
escaped its clasp.
She stopped short of the
blood. “Detective Harlow Quinn.” “Eva Kowalski.” “I know.” “That rarely precedes a pleasant conversation.”
Her voice held the precise
rhythm of lecture halls and reading rooms, though her fingers crushed the satchel flap. Quinn held out a gloved hand. “Shoes.” “I beg your pardon?” “Take off the right one.” Eva glanced at Reed. “He has already photographed it from every conceivable angle. One shot involved a ruler and made the whole process feel indecent.” “The shoe.” Eva removed it and passed it across. Quinn compared the sole with the nearest print. Same broken zigzag pattern. Same worn patch near the outer heel. Reed folded his arms. “Matching tread.” “Not matching damage.” Quinn pointed. The bloody print showed an intact zigzag where Eva’s sole had lost a triangular piece of rubber. Reed’s folded arms loosened. “Old photograph?” “Or another pair.” Eva tucked her hair behind her left ear again. “They stopped making that model fourteen months ago. I bought two pairs because the arch support is excellent. The spare pair vanished from my flat last week.” “Burglary reported?” “Nothing else had moved. I assumed I had misplaced them.” “You have a master’s degree from Oxford, access to restricted archives and a satchel full of books, but losing one shoe failed to trouble you?” “A pair. I lost a pair.” “That correction mattered to you?” “Accuracy usually matters to detectives.” Reed coughed into his fist. Quinn handed back the trainer. “Did you know him?” Eva looked at the corpse. Her throat worked. “His name was Emil Vane.” “You recognised him
quickly
.” “He brokered manuscripts, cursed objects, private collections. He also cheated at cards.” “What did he ask from the museum?” “The request slip will say.” “I’m asking you.” “A folio removed from Constantinople during the Fourth Crusade. The Catalogue of Unfastened Doors.” Reed looked from Eva to Quinn. “That sounds made up.” “Most titles do when translated by Victorians.” “What’s an unfastened door?” Eva’s gaze settled on something beneath the corpse’s left hand. “A breach. A passage between places that should not touch.” Quinn followed her attention. A small brass compass lay half hidden beneath the dead man’s fingers. Verdigris mottled its casing. Protective sigils crowded the face in rings of fine, black engraving. The needle
trembled
, though nothing disturbed it. “Bagged and logged?” “Photographed in place.” Reed nodded to the scene examiner. “Thought it might be the missing stock. Vane grabbed it before he died.” “He died before someone placed him here.” Quinn studied the fingers. Blood stained their tips, but the compass bore none. “He never touched it.”
She shifted the hand aside
without moving the object. The brass casing rested on a clean circle of wood. Blood surrounded it. Reed’s expression hardened. “Placed before the blood.” “Placed after the blood.” Quinn angled the torch. A fine transparent rim hugged the compass. “Wax seal. Whoever set it down protected the underside, poured blood around it, then melted the wax.” Eva took one step closer. “Don’t pick it up.” “That sounded less like advice.” “It was crafted by a Shade artisan. They make instruments that respond badly to warm hands.” Reed stared at her. “A what artisan?” “A Shade.” “Is that a surname?” “No.” Quinn looked at the compass needle. It did not point north.
It aimed across the tracks
at a tiled wall where an old advertisement promoted cigarettes with the promise that gentlemen preferred restraint. “What does it measure?” Eva’s lips compressed. “Proximity.” “To what?” “A supernatural rift or portal.” Reed gave a short laugh. Nobody joined him. Quinn drew an evidence bag from the examiner’s case, wrapped it around her gloved fingers and lifted the compass. The needle swung hard towards the wall. A vibration passed through the casing and into her hand. Not machinery. Not a loose spring. A
pulse
. Quinn set it back down. “Vane entered through that wall.” Reed glanced at the tiles. “There’s six metres of earth behind it.” “His boots have no track dust. Nobody dragged him down the stairs. The pool contains more blood than the body could have lost after death. Those prints implicate Kowalski, but the missing piece on her sole disproves them. The museum slip puts her name in his pocket. Someone wanted us to arrest her before we examined the scene.” “Why?” “Because she knows what the compass does.” Eva’s grip tightened on her satchel. “And because you would bring me here.” Quinn turned to her. “You?” “No. You.” Eva pointed to the corpse’s shirt. A dark mark showed beneath the open collar, close to the sternum. Quinn pulled the fabric aside. Someone had drawn a broken circle on the dead man’s chest. Three vertical cuts divided it. The lines carried a brown crust, not ink.
Her left wrist contracted beneath
the strap of her worn leather
watch
. Three years earlier, Detective Sergeant Morris had vanished from a locked evidence room. Quinn had found his blood beneath a steel cabinet and that same broken circle scratched into the floor. Professional Standards called it an unexplained death after six months without a body. Quinn had never included the symbol in her report. Reed watched her face. “You know it.” “Photograph it.” “Harlow.” “Photograph it.” The camera flashed. Eva crouched near the block, careful of the blood. “That is not a ritual mark. It’s a transit seal. The three lines represent passage, payment and return.” “What was the payment?” Reed’s scepticism had thinned. Eva looked at the teeth in the jars, then at the bone disc in an evidence tray. “Entry to this market requires a bone token.” The disc resembled a large ivory coin, yellowed at the edge. A tiny hole pierced its centre. Quinn picked up the evidence tray. “Human?” “Temporal bone. Cut from behind the ear.” “Vane’s?” Eva examined the corpse’s head without touching it. “No incision.” “Then whoever came through paid with someone else.” The compass needle
began to
twitch. Once. Twice. Tick-tock. Eva rose. “Put it down.” “It’s already down.” The brass casing shuddered against the wood. The needle whipped in a full circle, then snapped towards the tiled wall again. Along the track, the constable pulled off his ear defenders. “Ma’am?” A metallic groan rolled from the sealed tunnel. Dust trickled from the arch. The rails, dead for decades,
began to
hum. Reed reached for his radio. “Control, confirm all lines beneath Camden are isolated.” Static answered. Beneath it, a man counted backwards from thirteen. Quinn stared at the cigarette advertisement. A crack split the smiling gentleman’s face from forehead to chin. Black fluid pushed through the gap and ran upward across the tiles. Eva opened her satchel and dragged out a thick book bound in stained calfskin. “That compass doesn’t open doors.” The wall buckled. “What does?” “It tells whatever lives beyond them where to knock.” Tiles burst across the platform. Quinn seized Eva and hauled her behind the butcher’s block as a blast of stale air extinguished two work lamps. Reed drew his baton, saw what he had drawn, swore, and replaced it with his pistol. A train surged through the broken wall without rails beneath it. Its windows glowed red. Human silhouettes packed every carriage, their palms pressed flat against the glass. The train shrieked to a halt beside the abandoned platform. One door opened. A gaunt man in a torn charcoal suit fell onto his knees. Blood covered his shirt. A warrant card hung from his neck. Quinn knew the number before she read it. DS Morris lifted his head. “Harlow, run.” Something inside the carriage hooked black fingers through his mouth and ripped him backwards as every door on the train opened at once.
