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>

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>

Tomás Herrera vaulted the bonnet
of a black cab, struck the wet road shoulder-first and rolled beneath the swing of Quinn’s hand. “Police. Stop.” He came up running.
Quinn drove between two stalled
cars as horns blared around her. Rain polished Camden High Street into a ribbon of smeared brake lights. Tomás cut across the traffic, close enough to slap a delivery van for balance, and vanished into a narrow lane between a tattoo parlour and a shuttered bakery. She followed. Eighteen years taught Quinn how guilty people ran.
Thieves glanced back to measure
distance. Dealers shed evidence. Killers watched hands and waistbands. Tomás watched the roofs.
His short dark curls shone
with rain.
A brown leather satchel bounced
against his hip, the same one he had carried out of the Raven’s Nest forty minutes earlier.
Quinn had watched him leave
beneath the bar’s green neon sign, watched him check both ends of the Soho street, then followed his motorcycle north.
He had spotted her outside
Camden Town station.
Now he hooked his fingers
over the top of a steel bin and dragged it into her path. Quinn hurdled it. Her heel clipped the rim, but she caught the brick wall and kept moving. Pain travelled up her wrist.
Her worn leather watch knocked
against the bricks, its cracked face holding firm. Ahead, Tomás shouldered through a fire door.
Quinn hit it before it
closed. Heat and bass swallowed her.
She entered the back of
a crowded music venue, skidded across a beer-slick concrete floor and collided with a young man carrying plastic cups.
Lager burst over his white
shirt. “What the hell?” “Met Police.” “Does that mean you’re buying another round?” She shoved past him. Tomás threaded through the crowd beyond the stage. Coloured lights swept across his olive skin and flashed on the silver medallion at his throat. Saint Christopher. Patron saint of travellers, worn by a man sprinting towards somewhere no sane traveller would choose. Quinn forced a path after him. “Move.” A woman in silver horns turned and bared pointed teeth. “Buy me dinner first.” Quinn reached Tomás as he cleared the
dance
floor.
Her hand closed on the
satchel strap. The strap snapped. Tomás
lurched
forwards. Quinn landed against a pillar with the satchel clutched to her chest. For half a second, both of them stopped.
His warm brown eyes fixed
on the bag. Quinn opened her coat enough to show the butt of her pistol. “Don’t.” “You don’t understand what you’re holding.” “Then save us both the interview room.” “There won’t be an interview room if you open that.” Tomás stepped towards her. Quinn drew the pistol. The nearest dancers noticed. Screams cut through the music. Bodies surged away, knocking tables over and crushing cups underfoot. Tomás raised his hands. A pale scar ran along his left forearm, puckered and crooked beneath his soaked sleeve. “Detective, listen to me. Put the bag down. Walk out the way you came.” “On your knees.” “No.” “That wasn’t a negotiation.” “Neither is this.”
He tore the Saint Christopher
medallion from his neck and flung it at the overhead lighting rig. The chain wrapped around a cable. Every light in the venue died. Darkness struck. The bass coughed into
silence
. Quinn heard Tomás move.
She caught his sleeve, twisted
and drove him into the pillar. He grunted. An elbow slammed into her ribs.
Her grip loosened, then his
fingers found the satchel.
They fought without room for
finesse. Cloth stretched. A shoulder cracked against brick. Someone stamped on Quinn’s foot while fleeing. The satchel split open. Glass
shattered
between them. A sharp scent flooded the dark, copper and burnt rosemary, with something underneath that dragged Quinn three years into the past. A locked room in Whitechapel. Morris choking on a prayer he had never learnt. Black handprints blooming across the ceiling. Quinn released the bag. Tomás stopped fighting. “Oh, no.” A faint blue glow leaked across the floor. The liquid from the broken vial crawled against the slope. It moved uphill in thin, branching veins, avoiding boots and broken glass. Where it touched the pillar, letters appeared in the brickwork. Not painted. Not carved. Growing. Quinn aimed her pistol at Tomás’s chest. “What did you bring in here?” “Nothing that was meant to break.” The blue veins reached the Saint Christopher medallion. Metal hissed. The glow vanished. Emergency lights
flickered
on. Tomás seized the torn satchel and ran through a door marked STAFF ONLY. Quinn went after him. The door led into a service passage that stank of damp plaster and old cooking oil. Tomás crashed through stacked crates, scattering empty bottles. Quinn followed the noise down two flights of narrow stairs and into a kitchen where a cook stood over a smoking pan. “Back way?” The cook pointed with a knife. “He paid?” Quinn flashed her warrant card without slowing. “Put it on his tab.”
She burst through the rear
door and returned to the rain. Tomás sprinted across the courtyard ahead.
He no longer carried the
satchel. One hand pressed against his ribs. Blood darkened his shirt beneath the arm, the broken glass had found him.
He kicked through a gap
in a chain-link fence. Quinn holstered her pistol and climbed. Wet metal slid beneath her palms. Tomás staggered beyond a row of locked garages, recovered, then disappeared behind a boarded pub.
She dropped on the other
side. “Tomás.” His steps faltered. “You’re bleeding. That doesn’t improve with exercise.” “Neither does a gunshot.” “You’re not shot.” “Let us keep one miracle between us.”
His Seville accent thickened under
strain, rounding the words. Quinn followed him into another alley, this one choked with rubbish bags and discarded furniture. A dead television faced the wall. Its black screen flashed blue as she passed. At the end stood a rusted green gate chained shut. Tomás reached through the bars, found a concealed catch and pulled. The chain fell loose despite the padlock hanging from it. Quinn gained on him. Beyond the gate, a tiled stairwell descended beneath a faded roundel. The station name had vanished under layers of black paint. Council notices covered the entrance, each warning of structural collapse, asbestos and prosecution. Tomás took the stairs three at a time. Quinn caught the gate before it swung shut. “End of the line.” He looked back from the landing below. Blood striped his fingers. “For you, yes.” He continued down. Quinn entered. The traffic noise faded after the first turn. Water dripped through cracked cream tiles. Old advertisements clung to the walls, promising cigarettes, seaside holidays and cures for nerves. Someone had scratched eyes from every human face. At the foot of the stairs, Tomás limped through a ticket hall. Steel barriers blocked the far side. Dust lay thick across the floor, except for the dark tracks beneath his shoes. Quinn drew her pistol again. “Stop running.” He leaned on a ticket machine that had not taken a fare in decades. “I need what remains in that bag.” “You abandoned it.” “I abandoned the glass. The lining has a second pocket.” “And what’s in there?” “A dose.” “Of what?” Tomás glanced towards the barriers. “Something your courts have not named yet.” Quinn advanced. Her shoes crunched over flakes of fallen ceiling. “Three people left the Raven’s Nest in body bags this month. All three had puncture wounds at the base of the skull. All three had your number written inside their clothes.” “I treated them.” “Off the books.” “Your books have narrow margins.” “You lost your medical licence.” “I lost permission. The knowledge stayed.” A tremor ran through his wounded arm. He pressed harder against his ribs. Quinn stopped six feet away. “Who were they?” “People who trusted the wrong seller.” “What seller?” “A man who trades in memories.” “Names.” “Names change. Faces change. Hunger does not.” Quinn’s finger rested along the pistol frame. “The liquid upstairs wrote on a wall.” “Yes.” “You expected me to ignore that.” “I expected you to recognise a warning.” The ticket machine clicked beneath his hand. Quinn saw the movement. His thumb had pressed into a narrow coin return. “Step away from it.” “You followed me from the Nest. You chased me through traffic. You brought a weapon into a place where weapons remember every life they took.” “Step away.” “Your partner said that too.” The ticket hall shrank around her. Tomás’s gaze dropped to her left wrist, to the
watch
Morris had given her after she made detective. The leather strap had split twice since his disappearance. She had repaired it twice. Quinn crossed the distance and drove Tomás against the machine. The muzzle touched the soft flesh beneath his jaw. “You never met Morris.” “No.” “Then you have one breath to explain.” “He came here.” The old machine clunked. Something dropped into its return tray. Tomás reached down with two fingers and lifted a small yellow token. Bone, polished smooth, with a hole bored through its centre. Quinn took it from him. Warmth
pulsed
against her skin. “Where is he?” “Past the barriers.” “He died in Whitechapel.” “You never found a body.” “I found enough.” “No. You found blood. Teeth. Part of a hand.” Quinn pushed the pistol harder into his throat. “You read my file.” “I stitched him closed.” The barriers snapped open. Not one after another. All twelve slammed apart at once. Wind rushed from the tunnels and carried a confusion of smells into the hall. Hot sugar. Formaldehyde. Animal musk. Incense. Rot. Voices followed. Hundreds of them. Quinn looked beyond the barriers. The passage had held darkness seconds ago.
Now red paper lanterns hung
from its ceiling, stretching into the distance. Figures moved beneath them, wrapped in fur,
silk
, feathers and transparent plastic. Tables crowded the old platforms. Glass jars glimmered beside cages. A woman with antlers haggled over a black human tooth. Two boys in school uniform carried a wooden box that kicked from within. The abandoned station had opened its mouth. Tomás shoved Quinn’s arm aside and staggered through the barrier. She seized his collar. “You’re taking me to Morris.” “I’m taking the medicine to a child.” “You used his name to get this far.” “I used his name because it worked.” Quinn hauled him back. His face tightened as the wound at his ribs opened wider. “Where is he?” Tomás looked past her. The barriers
began to
close. The bone token in Quinn’s hand cooled. “You have six seconds, Detective. Stay here and arrest a bleeding man, or come down and learn why Morris begged me to let him die.” The nearest barrier struck Tomás’s shoulder. He slipped through before it sealed. Quinn caught the steel edge. Its motor whined against her grip. Beyond him, the underground market seethed across the tracks and platforms of the dead station. Canvas awnings sagged beneath strings of charms. Copper bowls held flames that bent towards passing customers. Vendors called prices in pounds, years and teeth. A huge pale creature crouched behind a butcher’s counter, cutting strips from meat that twitched under the knife. Quinn’s radio spat static. Then Morris spoke through it. “Harlow, don’t come down.” Her grip slackened. The barrier crushed against her knuckles. Pain sharpened her. She jammed the bone token into the gap, forced herself through and landed on the other side. The steel gates slammed shut behind her. Every voice in the market stopped. Hundreds of faces turned towards the service pistol in her hand. A bell rang once. Tomás went pale. “Put the gun away.” A vendor drew a curved black blade from beneath a bed of crushed ice. Another pulled a chain from a jar. It writhed around his wrist like a living thing. Quinn raised her warrant card. “Metropolitan Police.” The market erupted.
