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>

Herrera's elbow smashed the side
mirror off a parked delivery van.
Glass sprayed across the wet
tarmac.
Detective Harlow Quinn vaulted a
toppled rubbish bin and kept her eyes locked on his black leather jacket. Eighteen years in the Met taught you how to pace a pursuit.
You let the young ones
burn their lungs out in the first two hundred yards.
You wait for the panic
to sour their muscles. Herrera
wasn't slowing
down.
He cut left out of
Soho, leaving the green neon glow of The Raven's Nest behind them, and sprinted north toward Camden.
Quinn pumped her arms, her
boots splashing through oily puddles.
Her lungs burned, a sharp
reminder
of her forty-one years, and the worn leather
watch
on her left wrist slapped against her
pulse
point. Tick-tock. Three minutes since he bolted from the back alley of Silas's bar. Three minutes since she caught him scrubbing thick purple blood off the pavement. Human blood wasn't purple.
Morris's hadn't been, though the
things that killed him left stains just like it on the concrete three years ago. "Herrera!" He didn't look back.
He vaulted a low brick
wall, cutting through a cramped housing estate.
Quinn took the steps two
at a time, her military bearing keeping her centre of gravity low on the slick concrete.
They passed a row of
shuttered shops.
A neon kebab sign buzzed
in a grease-streaked window, casting a sickly pink sheen over a rotting mattress propped against a skip.
The smell of wet dog
and fried onions hung thick in the narrow passage. Herrera skidded around a corner, his trainers losing traction on the wet cobblestones.
He caught himself against a
rusted drainpipe, the heavy canvas medical bag strapped across his chest swinging wide.
Quinn closed the gap to
twenty paces.
She reached under her soaked
coat, her fingers brushing the grip of her baton. "Stop running, Tommy! It's just a question!" "Your questions come with handcuffs, Detective!" "Only when you sprint away from a crime scene!" "No body, no crime!" "Tell that to the gallon of blood in the alley!"
He ducked through a gap
in a chain-link fence. Quinn hit the fence a second later. The rusted steel links bit into her palms as she shoved herself through the narrow opening. A loose wire snagged her woollen coat, ripping the hem.
She wrenched it free and
charged
down a steep concrete ramp leading behind an abandoned Camden warehouse. The alley ended at a boarded-up London Underground entrance. Rusted iron gates, padlocked since the seventies, barred the tiled archway. Old concert posters peeled off the damp plywood like dead skin. Got him. Quinn slowed to a trot, drawing her baton and flicking her wrist. The steel shaft extended with a sharp metallic clack.
She wiped the water from
her brown eyes, her sharp jaw set. Herrera stood with his back against the iron gates, chest heaving.
His short curly dark brown
hair clung to his forehead. With his sleeves rolled up despite the
chill
, the jagged scar along his left forearm gleamed pale under the flickering streetlamp.
His hand went to his
throat, fingers wrapping around the silver Saint Christopher medallion hanging from his neck. "Nowhere left to go, Tomás." "Always somewhere to go in London." "Put the bag on the ground. Step away from the gate." "Can't do that, Quinn. This kit costs more than your pension." "NHS issue?" "Private practice." "The NHS struck you off two years ago for stealing plasma and administering unapproved compounds. Who are you patching up tonight?" Herrera's warm brown eyes darted to the padlock on the gate, then back to her baton.
He shifted his weight to
the balls of his feet. "A friend. Had a bad fall." "People don't bleed violet when they fall, Tommy. And they don't leave claw marks in brick."
His fingers tightened around the
medallion. The olive skin of his throat worked as he swallowed. "Walk away, Detective. Go back to your desk, write up a report on a burst main, and forget you saw me." "Like I forgot DS Morris?" Herrera flinched.
Just a fraction, a tightening
around the eyes, before his mask slipped back into place. "Don't know the name." "Liar. You know what tore him apart in that Rotherhithe basement. You're treating the things that did it." Quinn stepped forward. Five paces between them. Four. "Turn around. Hands behind your back." Herrera reached into his pocket. Quinn tensed, raising the baton, ready to strike his collarbone.
He pulled his hand out
slowly
, palm open. A small, jagged piece of pale yellow bone rested against his skin. Strange carvings scarred its surface, dark as dried tar. "Don't follow me down here, Quinn. For your own sake." "Drop it." He didn't drop it.
He pressed the bone token
flat against the rusted padlock on the Tube gate. The metal didn't click. It hissed. A smell like scorched hair and ozone rolled out from the boarded-up entrance. The heavy iron chain didn't fall away, it dissolved into a greasy grey mist for a split second. Herrera threw his
weight
backward.
He fell right through the
solid iron bars as if they
were made
of smoke, tumbling onto the dark steps beyond. Quinn froze. Her mind, trained on forensics, CCTV, and ballistics, rejected the image. The iron bars solidified again with a low hum. Herrera scrambled to his feet on the other side of the gate. He looked up at her through the rusted diamond mesh, his breathing ragged, and bolted down into the pitch-black stairwell. Quinn stared at the padlock. Solid steel. Untouched. She looked down at the damp concrete by her boot. In his scramble, something had snapped off Herrera's bag or pocket. A second bone token lay in a dirty puddle, half-submerged. She crouched and picked it up. The bone felt warm, vibrating against her calloused thumb like a trapped wasp. Backup was a radio call away. Protocol dictated she secure the perimeter, call in CSU, and wait for daylight and a bolt cutter. Protocol got Morris killed in the dark while she waited by the squad car. Quinn pressed the bone against the rusted lock. Cold fire shot up her arm. The iron bars blurred, turning translucent and watery.
Before the sensation could stop
her, she lowered her shoulder and lunged through the gate. It felt like wading through chest-deep spiderwebs. Thick, freezing strands clung to her face and coat, smelling of
grave
dirt and stagnant river water.
Then she stumbled out the
other side onto cracked Victorian tiles. Behind her, the iron gate snapped back into solid reality, locking her in. She clicked on her torch. The beam cut through the grime of the disused station. Tiles the colour of dried blood lined the walls, spelling out a station name that had
been chiselled
off the plaster decades ago. Water dripped from the arched ceiling. Pitter-patter. From the
depths
of the escalators below, a low roar
echoed
up the shaft. Not a train. Voices. Hundreds of them, layered over the clinking of glass and the hiss of open flames. Quinn killed her torch, unclipped her radio, and turned the volume knob to zero.
If that thing chirped down
here, she was dead. She tucked the baton into her belt, pulled her coat tight to hide the shiny silver buckle of her utility rig, and walked down the dead wooden steps of the escalator. The tunnel opened into the main concourse and the twin platform tubes beyond. Quinn stopped at the bottom of the stairs, pressing her back against a tiled pillar. The abandoned station
pulsed
with life. Braziers filled with green and violet fire burned along the edge of the empty train tracks, casting long, twisting shadows across the platforms. Market stalls made from salvaged timber,
velvet
drapes, and rusted sheet metal crammed every inch of the concourse. The air tasted metallic, heavy with burnt sage, copper, and raw butchered meat. People crowded the narrow aisles. Except half of them didn't move like people. A man in a bespoke Savile Row suit walked past Quinn's pillar. When he turned his head to inspect a rack of glass vials, his eyes had no whites, only solid pools of
glistening
black oil. Beside him, a woman with skin the texture of birch bark haggled with a vendor over a wooden crate filled with writhing, skinless eels. Quinn's hand went to her hip, her fingers curling over the cold steel of her baton. Her heart hammered against her ribs. Every cop instinct screamed at her to draw her weapon, to take control of the room. Every survival instinct told her she wouldn't last ten seconds. She spotted the black leather jacket thirty yards away, near the far end of the northbound platform. Herrera
was weaving
through the crowd, one hand clutching his medical bag, the other pushing past a
hulking
figure wrapped in a stained butcher's apron. Quinn stepped out from behind the pillar. She kept her chin down, her eyes fixed on the back of Herrera's head, letting her military stride relax into the slouched, indifferent walk of a local. She passed a stall draped in cured hides. Small, mummified hands hung from twine strings above the counter, their shrivelled fingers curled into hooks. The vendor, a gaunt man with teeth filed to points, leaned over a brass scale. "Fresh mandrake root, darling? Dug up at the crossroads last midnight." "Just browsing." "Wait." The vendor leaned closer, his nostrils flaring. His tongue
flicked
out, tasting the air between them. "You smell like starched wool and magistrate's ink." Quinn didn't break stride. She shoved her hands into her pockets and cut between two tall figures draped in hooded grey cloaks, losing the vendor in the crush of bodies. Ahead, Herrera stopped at an alcove carved into the tiled wall where an old ticket booth once stood. Heavy crimson curtains hid the interior. He glanced over his shoulder,
scanning
the market, before slipping through the fabric. Quinn reached the alcove ten seconds later. A rusted brass plaque bolted to the brickwork above the curtain read *
Apothecary
*. She stood beside the brickwork, listening. "I need six vials of nightshade distillate and a spool of silver-gut suture." Herrera's voice was tight, breathless. "Silver-gut went up, little doctor." A voice like grinding stones answered from behind the curtain. "Moon's full tomorrow. Market moves to the Rotherhithe tunnels. Transport costs." "Don't play games with me, Vane. I have a bleeder at the Nest." "Then pay the toll. Or give me something better than coin." Quinn shifted her
weight
to peek through the gap in the crimson
velvet
. Her boot crunched down on a discarded glass ampoule. The conversation inside the booth died instantly. Quinn didn't wait. She ripped the curtain back and stepped into the cramped booth. Herrera spun around, his hand dropping into his medical bag. Behind the counter stood a man with no eyes, just smooth, scarred skin stretching from his brow to his cheekbones. Two pale, hairless hounds the size of calves lay at the vendor's feet. As Quinn entered, both beasts raised their heads, their split jaws parting to reveal rows of translucent, needle-sharp teeth. "Harlow," Herrera breathed, all the colour draining from his olive skin. "What did you do?" The blind vendor tilted his head toward Quinn. A slow, wet smile stretched across his face. "Not a customer, little doctor?" "She's with me," Herrera said
quickly
, stepping between Quinn and the counter. "Just a courier. We're leaving." The vendor's smile widened. He raised a long, grey finger and pointed straight at Quinn's chest, right where her warrant card sat tucked inside her breast pocket. "Couriers don't carry the Queen's iron, Tomás. And they don't reek of old ghosts." The vendor snapped his fingers. "Hounds. Meat." The two hairless beasts lunged over the counter.
