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>

"Keep your hands where I can see them."
Detective Harlow Quinn stepped through
the cordon and ignored the constable’s flinch.
Her worn leather watch sat
heavy on her left wrist, ticking against the
pulse
in her skin as she ducked under the barrier tape.
The air down there carried
a rotten-sweet stink, incense and old drainage and something metallic beneath it.
A line of lanterns cast
a sickly amber sheen over the tiled tunnel, and the abandoned station beyond it had turned into a nest of stalls, tarps, and iron cages. One of the market’s stone-faced traders lay sprawled beside a shuttered apothecary booth, his throat opened from ear to ear.
Quinn crouched, one knee cracking
against the concrete, and held two fingers near the wound without touching it.
Blood had soaked into the
collar of a dark coat and pooled in the grooves between the station tiles.
Too much for a street
cutting.
Too little for a clean
kill. "Detective Quinn."
A voice cut through the
low mutter of uniforms and the scrape of camera legs. "Glad you could drag yourself into the underworld." Harlow turned.
Detective Sergeant Alistair Vale stood
near the ticket barriers, hands shoved into his coat pockets, his tie loosened and his expression already bored with the dead.
He had the pale, pinched
look of a man who had spent two days drinking bad coffee and
calling that diligence
. "Vale." His gaze
flicked
over her, lingering on the notebook in her hand. "You look like you took a wrong turn into a goth convention." "Funny. You here to help, or to ruin the scene with that mouth of yours?"
He stepped closer and stopped
beside the body. "You're missing the obvious. Snuffing one of their own solves half our problem. Market clears, evidence disappears, everyone lies, we go home."
Quinn lifted her eyes to
the dead trader’s hands. "Then explain the hands." Vale folded his arms. "What about them?" She pointed.
The corpse’s right hand clutched
a bone token so
tightly
that the knuckles had split around it. The left hand lay open, palm up, fingers curled inwards as if he had reached for something and never made contact. "He was carrying access," she said. "No one dies with entry in their fist unless they got it out at the end." Vale snorted. "Or he panicked. The whole place goes feral when blue lights show up." "The market’s underground, not stupid." "That’s news to half the people in this city."
Quinn ignored him and leaned
in.
The dead man’s eyes stared
at the ceiling tiles, but the pupils sat tiny, pinched hard by something that had hit him before the blood loss did. No bruising around the mouth. No defensive cuts on the forearms.
His cuffs had pulled back
enough to show pale skin marked with a ring of black ash around the wrist.
She touched the cuff with
the back of one finger. The ash rubbed loose. Vale watched her. "You’ve got that face." "What face?" "The one that says the rest of us are idiots."
She looked up at the
sign above the shuttered booth. Alchemical tinctures, moon salts, tooth powders, all painted in faded gold. Beside the lettering, someone had scratched a symbol into the enamel, a spiral cut through by a single line. Recent. The gouge still gleamed. "Who found him?" "A trader called Marek. Claims he came down for a meeting and found the place like this." Vale jerked his chin towards the platform. "Claims he saw someone running. Black coat. Hood up. Says it was one of yours." "Mine?" "Police. Human. Choose the adjective." Quinn stood and
scanned
the station. The Veil Market sprawled through the old platform like a
clandestine
city built out of theft and superstition. Stalls leaned against tiled pillars. Chains hung with drying herbs, charms, teeth, glass bottles filled with pale fluids. Beyond the body, a stall selling charms made of bent silver fingers had been half tipped over. A rack of hand mirrors lay
shattered
, each shard catching the lantern light and throwing it back in sharp, nervous flashes.
She turned to the nearest
constable. "Witnesses?" "Several, ma'am. None of them agree on anything." "Convenient." "Their stories are changing," Vale said. "I told them
not to contaminate each other, but you know how these people are
." Quinn’s stare moved to him. "These people?" He gave a small shrug. "You know exactly what I mean." She did know.
She also knew the dead
man’s throat had not been cut by any human blade she trusted. A narrow alley of stalls ran off the platform towards a closed curtain of black
velvet
. Quinn followed the blood trail there.
It did not trail, not
properly. It dotted. One drop here, another there, then a smear where someone had dragged the corpse or where the body had jerked after the wound opened. On the canvas wall beside the
velvet
curtain, she found a handprint in blood, fingers spread wide.
Then she found a second
mark beneath it. Not blood. Soot.
She squatted and touched the
floor. Fine grey grit clung to the cracks between the tiles, and the texture bit her fingertip like ground bone.
She lifted her hand and
rubbed the ash between finger and thumb.
It smelled faintly of church
candles left too long in a crypt. Vale glanced over her shoulder. "Found something?" "Less than I want." "That bad, is it?"
She stood and looked past
him to the shuttered main tunnel. A pair of officers kept the crowd back. Traders and dealers and the market’s assorted parasites gathered in pockets of suspicion, their whispers running through the station like mice through wallboards. Nobody met her eye for long. "Who sealed the market?" she asked. Vale blinked once. "No one sealed it. We arrived, cordoned off the area, and waited for you lot to stop treating homicide like theatre." "Then why are the exits clear?" He turned to look. The passageways leading out of the platform were open, unblocked, too neat. No toppled crates, no deadlocks, no broken barriers. For a place full of panicked smugglers and terrified opportunists, it looked curated. Quinn pointed with her pen. "If this had started in the market, those exits would be a mess. Somebody would have shoved carts, broken shelves, dropped goods. Instead, the walkway’s clean." Vale frowned, then shot a look along the platform. "Could be because they ran through the other side." "The other side where?" He gestured vaguely. "Back corridors. Staff tunnels. Whatever the hell they call them down here." "The traders call them nothing because they don’t exist on any plan." One of the market folk, a thin woman with catlike eyes and a silver hoop through one nostril, edged closer to the tape.
Her gloved hands shook around
a paper cup.
She spoke without looking directly
at Quinn. "He didn’t die here." Vale gave a short laugh. "Well, that narrows it down to every body in London." Quinn turned to the woman. "Tell me what you saw." The woman’s eyes
flicked
to Vale, then back to Quinn. "Nothing. Not properly. I heard the bell first." "Bell?" Vale said. The woman swallowed. "A small one. Brass, I think. A little ding, like a pet collar. Then the lights went low. Not out. Low. After that, everyone started staring at the wrong corners." Quinn’s pen stilled. "Wrong corners." The woman nodded once. "You know. The places where nothing stands until something wants to." Vale’s mouth tightened. "That’s helpful." "It’s more helpful than your usual contributions," Quinn said. She faced the woman again. "Did anyone leave with him?" The woman licked her lips. "A man in a dark coat. No face. Or I couldn’t keep it. He held something brass in his hand." Vale raised an
eyebrow
. "Face no-face, brass in hand. We’re
really
cooking now." Quinn stepped away before irritation sharpened her voice. She moved to the dead man again and looked at the blood on the floor from another angle. The drops formed a thin line towards the shuttered apothecary booth, but not from the body. From somewhere behind it. She went around the booth. The narrow space behind it smelled of vinegar, mildew, and hot electrical wire. A broken crate lay smashed in the corner. On the wall, someone had painted a symbol in black tar. The same spiral, cut by the same line. Below it sat a brass compass. Small. Worn. Verdigris crusted the casing, and protective sigils ringed the face. The needle spun once, twice, then settled hard towards the east wall. Vale saw it and stepped in beside her. "That yours?" "Not remotely." "Then don't touch it." Quinn ignored him and took the compass in her gloved hand. The metal felt cold enough to sting through the leather. The needle jumped, then locked again, pointing past the wall and into the service passage behind the booth. She looked at the wall itself. Old tiles, grime, water damage. Nothing unusual, except the mortar along one seam had
been disturbed
. Fresh dust clung to the edges in a pale line. Someone had moved the panel. "Get a torch." Vale gave her a flat look. "You are aware this is a crime scene, not your private hobby cave." "Now." A constable handed over a lamp. Quinn pressed the beam to the seam and
traced
the line down. At knee height, a notch had been cut into the tile. Not with a blade. With something blunt and heavy. She ran her fingertips along the edge, then smiled without
warmth
. "Well, that’s insolent." Vale peered in. "What is?" "This wasn’t a murder. It was a removal." "Of what?" Quinn pointed at the wall. "Of a door no one wants listed in the paperwork." She hooked a fingernail into the notch and pulled. A hidden panel shifted with a damp scrape. The smell that came out hit them both at once, stale water, candle wax, and the sharp, clean bite of ozone. Behind the panel, a narrow stair cut down into darkness. One of the constables muttered, "No one mentioned that." "Of course not," Vale said. "Because this day needed another surprise." Quinn slipped through the gap before anyone could object. The passage tightened around her shoulders as she descended. The compass
pulsed
faintly in her hand, the needle dragging harder the deeper she went. The walls here wore old concrete skin and someone’s newer rituals, chalk circles over flaking paint, salt packed into cracks, a smear of something dark and resinous across the lower step. Halfway down, she stopped. A smear of blood crossed the stair.
Then another, then a line
of it dragged towards a low door at the bottom. The blood did not drip from the steps above. It had
been laid
here afterwards, dragged into place like a signature. Vale’s voice floated down from behind her. "You’re not seriously going in there alone." Quinn glanced back. "You can leave if the paperwork frightens you." He opened his mouth, then shut it when the compass needle gave a sudden twitch. At the bottom of the stairs, the low door hung half open. Someone had raked the paint off it with a blade, revealing wood underneath, old and swollen with damp. The brass numbers on the front had
been scratched
away. Beyond it lay a storage room packed with crates, bundles, and hanging cages full of dead moths pinned to black
silk
. In the centre of the room stood a little brass bell on a table. Next to it, folded
carefully
, sat a Metropolitan Police warrant card. Quinn snatched it up. Her own face stared back from the plastic, younger by three years, the edges frayed, the photo cracked through one corner. DS Morris’s old number had
been written
on the back in neat black ink. Vale came up beside her and went still. "That’s impossible." Quinn did not answer. Her eyes tracked the table instead. Under the card lay a single wet footprint, small and bare, with blood pooled in the arch. Then the bell rang. Once. Bright. Close. Hungry. The compass in Quinn’s hand spun so fast it hissed against its casing, and every moth in the cages burst against the wire at once as the hidden room behind the crates slammed open with a crash of splintering wood.
