You are an expert and award-winning novel writer in the dark Thriller 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>
User/Human

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 thriller genre. A detective is pursuing a suspect through rain-soaked city streets at night. The chase takes them from the street level down into an underground market. The detective must decide whether to follow the suspect into unfamiliar and potentially dangerous territory. 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>

He slammed into the kerb
and kept running.
Quinn hit the pavement a
heartbeat later, her boots skidding on the wet stone as a black cab sprayed the road between them.
The suspect had burst out
from the side entrance beside the green neon of the Raven’s Nest, one hand locked around a satchel, the other clenched on something pale that flashed once under the sign and vanished into his fist. “Oi. Stop.”
He glanced back and grinned
through the rain, all teeth and no fear. “Catch me then, detective.” Quinn lengthened her stride.
The crowd on Camden High
Street split and swore as he carved a hard line through them, shoulder-checking a woman with a plastic carrier bag and sending a box of doughnuts skittering across the road. Wet flyers slapped at lampposts. A bus hissed by.
The suspect ducked round a
parked van, cut into a narrow lane, and Quinn followed close enough to smell him, cheap cologne fighting with sour sweat.
He wore a dark hooded
coat and trainers with luminous soles that flared and smeared in the puddles. Not a local. Not a mugger either. Too clean on the edges, too certain where he wanted to go.
The lane spat them back
out beside a closed kebab shop.
A steel shutter clanged in
the wind.
He vaulted a stack of
milk crates, landed badly, and still kept moving.
Quinn saw the pale thing
in his fist again, a carved sliver on a leather cord. Bone. Token. Her jaw tightened. “Hand over what you nicked.”
He shot her a look
over his shoulder. “Finders keepers.”
He swerved round a corner
shop with barred windows and a neon lottery sign buzzing above the till.
The owner stood inside behind
a mountain of scratch cards, eyes wide, one hand frozen around a broom.
Quinn flashed past the doorway
and heard the man bark something in a language she did not catch.
The suspect hit a side
street and the city changed around them.
Pubs gave way to shuttered
workshops, then to a stretch of graffiti-smeared brick and boarded windows. Someone had spray-painted a crown over an eye on the wall. Fresh paint, recent. Quinn clocked it and kept running. The man ahead did not slow.
He reached the mouth of
an abandoned station entrance ringed with iron railings and a sign half-hidden under stickers and grime. No service. No entry. The steps beneath it descended into darkness. Quinn raised her voice. “Police. One more move and I break your ankle.”
He spun at the top
step, breath heaving, rain running off the hood in dark strings. For a second he looked younger, barely out of his teens, all sharp cheekbones and panic.
Then his expression hardened and
he jammed the bone token against a rusted panel beside the gate. The panel clicked. Quinn slowed just enough to notice the smell rising from the stairwell, damp concrete, old oil, metal touched with something bitter, like burnt herbs. The man backed down the steps. “You don’t want this place.” “Too late.”
She reached him as he
turned and vanished below. Quinn grabbed the rail and took the stairs fast, two at a time. The light from the street thinned behind her. Graffiti crawled over the tiled walls, layers of tags, sigils, half-scrubbed symbols that looked too deliberate to be art. At the bottom, an old ticket barrier stood open, its turnstiles removed, its metal frame scarred with knife marks and candle wax.
He shoved through a black
curtain and disappeared. Quinn followed. The air changed at once. Heat. Spice. Smoke. Voices. The tunnel ahead opened into a cavern of stalls, tarpaulin roofs, dangling bulbs, and glass cases lit from beneath by bruised purple light. People moved between them in coats the colour of soot, their faces half-hidden beneath hoods and scarves. A woman sold jars of something that glimmered like coins in brine. A man with silver rings laid out bones on a
velvet
cloth.
Somewhere nearby, a radio hissed
under a tinny jazz station. The Veil Market. Quinn stepped over the threshold and the entire place
seemed to
notice. The suspect
was already weaving
through the crowd, pushing past a stall piled with enamel charms and rusted keys. A trader shouted at him. “You owe for the last
charm
, Jonas!” He did not look back. Quinn pushed after him, her badge still pinned inside her coat, her hand resting near it out of habit. Eyes tracked her. Conversations faltered.
She caught pieces, quick and
sharp. “Police?” “No, look at her boots.” “Nothing good comes down here unless it’s lost.” The suspect vanished behind a hanging curtain of beadwork and fish vertebrae. Quinn followed into a narrower passage lined with cramped stalls. One sold folded maps that changed when no one watched. Another sold little stoppered bottles filled with ink-black liquid. The smell turned her
stomach
. Rotten fruit. Iron. Tallow. A hand shot out from a doorway and blocked her path. Tomás Herrera stood there under a buzzing strip light, sleeves rolled to the elbow, olive skin damp with sweat, a white cloth in one hand and blood on the cuff of his shirt.
His short curls clung to
his forehead. The Saint Christopher medallion at his throat flashed when he moved.
He looked at Quinn, then
at the badge line under her coat, then back at her face. “Of course. You picked tonight.” “Move.”
He tilted his head towards
the passage the suspect had taken. “That one came in half dead and all nervous. If he led you here, he did not come to buy sweets.” “Tomás, out of my way.”
His gaze flicked to the
people gathering nearby. A woman with a black veil. A tall man in a fox mask. Two brothers with matching scars along their throats. The market had gone quiet in layers, not all at once, the way a room changed before a fight. “You are not dressed for this place, detective.” “Neither are you.” That pulled the smallest twitch from his mouth. “Fair.” The suspect burst back through the curtain at the far end of the passage, eyes huge now, one cheek split open, blood shining on his jaw. He pointed straight at Quinn. “She’s police.” The word dropped through the market like a knife. Voices rose. A stallholder reached under the counter. Someone kicked a stool aside. Quinn took one step towards the suspect and the crowd swallowed him again.
She caught only flashes, the
pale bone token in his hand, a
glint
of teeth, a shoulder slammed into a wall of hanging metal charms. “Jonas, you absolute fool,” Tomás muttered. Quinn shot him a hard look. “You know him.” “I know many idiots. That one owes me for stitches.” A bell rang somewhere deeper in the market, a flat and ugly sound. Not an alarm, a warning. The people around them
began to
shift, not away, towards. One man lifted a brass trinket to his lips and blew a single note. The reply came from somewhere unseen, low and human and wrong. Quinn turned her head, tracking the movement. A side corridor opened beyond a butcher’s stall, its walls blackened with soot and old posters. The suspect had
gone that way
.
If he reached the back
rooms, she would lose him in a warren of service passages and private doors.
If he carried whatever he
had stolen into the wrong hands, it would vanish into the market and into the city with it. She reached for the curtain. Tomás caught her wrist. “Not that one.” Quinn twisted free. “I am not asking.” His grip tightened for a second, then fell away. In the strip light his eyes looked older than his face. “That corridor belongs to people who do not like uniforms, badges, or questions.” “Lucky for me, I left all three at the door.” “You should have left your life there too.” She stepped past him. The corridor stank of mildew and hot wiring. Quinn moved fast, one hand against the wall, the other low and ready. Her boots crunched over broken tiles. At the first junction she found blood on the floor, a fresh smear leading left. The suspect had dragged a sleeve across it. He had gone in a hurry, and someone had followed. A door ahead swung inward on its own. Quinn stopped. The room beyond held shelves, a desk, and rows of tagged envelopes tied with string. Information. Names. Dates. Teeth in little paper packets. A desk lamp glared over a ledger so thick it bowed the plank beneath it. The suspect stood at the far end, one hand pressed to his bleeding cheek, the other reaching for a drawer. He looked up at her and froze. “You shouldn’t be here.” Quinn stepped into the room and the door snapped shut behind her. “Neither should you.” His hand closed around something in the drawer. He yanked it free, and Quinn saw the shape of it in the lamp light, a compact black pistol, old and well used, the grip wrapped in electrical tape. He raised it. A voice came from the dark corner by the filing shelves. “Put that down.” Quinn swung towards the sound. A woman stepped into the light, face half-covered by a scarf, one gloved hand resting on a crowbar. Her eyes landed on Quinn’s badge line and sharpened. The suspect’s mouth
trembled
once. “You said this place would keep me safe.” The woman smiled without
warmth
. “It did. Until you brought a copper with you.” Quinn reached for her weapon as the room erupted, the suspect jerking the pistol towards her, the woman lunging with the crowbar, and from the corridor outside came Tomás’s voice, clipped and
suddenly
urgent. “Harlow, move.”
