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>

Quinn caught the chain before
it struck the guard’s teeth. “Bone token,”
he snarled, reaching for her
coat.
She held the little white
disc between two fingers.
The guard’s hand stopped an
inch from her lapel. Around them, the market fell quiet.
Canvas awnings sagged over stalls
of bottled smoke, silver knives and jars whose contents pressed damply against the glass. “Police,” Quinn said. “I’m here for the body.” The guard looked past her, towards the abandoned ticket hall. Then he unhooked the chain. “Don’t touch what you don’t understand.” “I’ll add that to the report.” She ducked beneath the chain.
The guard let it snap
shut behind her.
The market’s last customers watched
from under their hoods as she crossed the old station floor.
Their faces caught the yellow
light in pieces: one eye, a row of teeth, a cheek stitched with copper wire. No one asked to see her warrant card. No one asked what a detective wanted in a place that had no place on any London transport map. At the far end of the ticket hall, a uniformed constable stood by a booth with one hand on his radio.
He had gone pale beneath
the grime on his cheeks. “Detective Quinn. It’s inside.” “Who found him?” “Market security. They say he’s one of theirs.” “Names?”
The constable glanced towards the
watching stalls. “They won’t give any.” “Then they can explain that to my sergeant.”
A strip of police tape
crossed the booth entrance.
Quinn lifted it and stepped
through.
The dead man sat behind
the counter with his chin lowered to his chest.
A black spike pinned his
lapel to his shirt.
His hands rested on the
counter, palms down, as if he had been waiting to serve the next customer.
Someone had brushed his grey
hair into a neat side part.
A chalk mark circled his
throat.
DS Bell crouched beside the
booth, gloves on, notebook balanced against one knee. “Market execution,” he said. “They’ve dressed it as a warning. Spike through the heart, mark round the neck. No blood, so I’m guessing they used something clean.” Quinn leaned close to the man’s chest without touching him. The spike pierced cloth, but the shirt beneath showed no tear.
She eased the fabric aside
with the end of a pen. No wound. No blood. “Not through the heart.” Bell followed her gaze. “A prop, then.” “A message, perhaps.” She studied the chalk ring. It looked too tidy. The line passed beneath the man’s collar, then appeared again at the nape. Someone had drawn it while he sat upright. “Any blood on the floor?” “Not a drop.” “On his clothes?” Bell pointed to the man’s cuffs. “Nothing. We’ll know more when the pathologist gets here.” Quinn watched the dead man’s hands.
His right thumb pressed hard
against the counter’s edge. The left fingers curled inwards, stiff but not fully closed. “What did you move?” “Nothing. I checked for a
pulse
. Constable checked his pockets.” The constable stood outside the booth. “I didn’t find anything, Detective.” Quinn turned back to the body. A pale line crossed the skin beneath the man’s
watch
. The strap had gone with someone else, or someone had taken it. She looked at his nails. A dark smear clung beneath one,
not dirt, but a greasy black grit
. “Where does this booth open?” Bell pointed to a narrow door behind the counter. “Store cupboard. It’s locked.” “Key?” “Security have it.” Quinn crossed to the door. No scrape marks around the lock. No dust on the handle. The constable fetched a squat man in a leather apron, who kept his eyes on the floor as he handed over a ring of keys. The cupboard held a mop, a cracked bucket and three boxes of old station notices. Quinn checked the floor. Dust lay smooth across it, except for the round marks left by the bucket and the flat rectangle beneath the boxes. No footprints. No sign that anyone had entered recently. She returned to the booth. “If he was killed here, the killer left no trace.” Bell tapped his notebook against his palm. “They could have wiped the place.” “Then they missed the dust in the cupboard.” “Different route out?” “Through a locked door?” “Not every door needs a key down here.” He had a point. The market had no interest in ordinary locks. Quinn moved around the booth, studying the floor. The dust held several shoeprints near the counter. One set led in from the ticket hall. A second set
seemed to
lead away. She crouched beside them. “Those are one set,” she said. Bell lowered himself beside her. “They go in and out.” “Look at the toes.” The prints nearest the booth pointed towards the counter. The ones leading away pointed the same way. Bell frowned. “Someone walked backwards?” “Across the entire hall, in a straight line? They’d have fallen over the stall legs.”
She traced the outer edge
of a print without touching it. The tread showed a split crescent beneath the heel, the same mark in each impression. “They made the exit trail with a stamp,” Quinn said. “Or a single mould. The depth doesn’t change. See? Heel, toe, same pressure each time. They wanted us to think someone came and went through the hall.” Bell rose. “And the real killer used the cupboard?” “Not unless they floated through it.” A dull click came from the dead man’s left hand. Quinn snapped round. The fingers had shifted against the counter. Bell pulled his radio from his belt. “Don’t,” Quinn said. The dead man’s hand stayed still. Something brass showed beneath his curled fingers, small and round, its green-stained casing half hidden by the cuff. Quinn eased it free with her gloved hand. A compass. The face bore fine marks cut around its rim. Not numbers. Not letters she knew.
Its needle trembled, then swung
towards the tiled wall behind the booth. Bell gave a short laugh with no humour in it. “Someone’s left you a souvenir.” Quinn turned the compass in her hand. The needle swung with the casing, then settled in the same direction.
She took two steps to
the right.
It pointed back towards the
wall. “Not north,” she said. “You’re sure?” “I’ve spent eighteen years being sure about things that turned out to be wrong. I’m sure it isn’t north.” The needle’s tip
quivered
against the glass. Bell stood between her and the wall. “You think he came through it?” “I think something in that direction matters.” “Rift, portal, secret passage. Pick your fancy.” Quinn’s eyes went to his face. “You’ve heard of those?” “Down here, I’ve heard of worse.” The chalk circle. The false wound. The staged footprints. The missing
watch
.
She looked at the dead
man’s posture again.
His shoulders sat too squarely
against the chair. His head hung forward, but his coat bunched beneath the collar as though someone had lifted him by the back. “Help me look at his spine.” Bell pulled on a fresh pair of gloves. Together they eased the body forwards. The dead man’s jacket fell open. A wide bruise spread across the back of his neck, dark at the centre, fading towards the jaw. Quinn pressed two fingers to the base of his skull. “Here,” she said. “And here.” Two small marks sat behind the ears. Not cuts. Bruises, shaped like fingertips. “Strangled,” Bell said. “Or held down while someone tightened a cord. But where’s the cord?” “No fibre. No ligature mark under the chalk.” “Because the chalk came after.” She looked at the body’s back. A faint grey film clung to the coat between the shoulder blades. She touched it with a swab. The dust came away black. The same greasy grit from beneath the man’s nail. Quinn checked the floor behind the chair. No matching smear. She checked the booth’s narrow doorway, the ticket hall, the false footprints. Nothing. “His back touched something dirty,” she said. “Something that left residue.” “The floor?” “Then we’d have it here.” “Someone carried him.” “Someone carried him upright, without brushing the walls or leaving a mark. Through a locked cupboard full of dust.” Quinn closed her fingers around the compass. Its casing felt warm. “Or they brought him through that wall.” Bell’s
eyes narrowed
at the tiles. “There’s brick behind them.” “You checked?” “I looked.” “That isn’t the same thing.” Quinn tucked the compass into an evidence pouch. The needle still pointed towards the wall. A low hum passed through the booth. The bulbs overhead dimmed. Across the ticket hall, a bottle burst on a stall. The watching crowd scattered, their shoes scraping over stone. Bell reached for his radio. Static swallowed his first words. Quinn stepped towards the tiled wall. A dark line had appeared between two cream tiles. It ran from the floor to the ceiling, thin as a hair. “Back,” she said. Bell took one step towards her. “What is that?” The line widened. Cold air pushed through the gap, carrying the smell of wet earth and old pennies. The compass needle struck the glass once, twice, three times. Quinn’s left wrist tightened beneath her worn leather
watch
. She raised her hand, palm out, and drew her sidearm with the other. The wall split. A hand slid through the opening, pale fingers closing round the edge of the tile. A silver police warrant card dangled from its wrist. Quinn knew the cracked leather sleeve. She had watched it vanish with DS Morris three years ago.
Then a voice came through
the gap. “Harlow.”
