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>

Detective Harlow Quinn slammed her shoulder into the fleeing figure, the impact jarring her teeth. Rain lashed her closely cropped salt-and-pepper hair, turning the Soho pavement into a treacherous mirror. The suspect twisted free, boots skidding on wet concrete, and bolted toward the narrow alley behind The Raven's Nest. She gave chase without hesitation. Her worn leather watch dug into her wrist as she pumped her arms. Eighteen years on the force had taught her the rhythm of pursuit: breath steady, eyes locked on the target's back, mind already cataloguing escape routes. This one moved with unnatural grace, dodging puddles she would have splashed through. Too clean. Too quick. "Stop! Police!" The words ripped from her throat, raw against the downpour. The suspect glanced back once. A flash of olive skin, short curly dark brown hair plastered to his scalp. Tomás Herrera. She had his file memorized. Former paramedic. Supplier of off-the-books care to the sort of people who shouldn't exist. The clique. He veered left at the alley's mouth, towards the abandoned utility door half-hidden behind overflowing bins. Quinn's lungs burned but her stride lengthened. Morris's face flickered in her memory, three years dead in circumstances that still smelled wrong. Supernatural, her partner had whispered before the end. She'd dismissed it then. Not anymore. The door banged open ahead of her. She followed, descending concrete steps two at a time into darkness that swallowed the city's neon glow. Water dripped from above, each drop echoing like a countdown. Her hand found her torch. The beam cut a harsh white path along damp brick walls covered in layered posters advertising gigs long forgotten. Herrera's footsteps echoed ahead, fading. She pushed harder, ignoring the stitch in her side. The passage narrowed, forcing her to turn sideways. Rust flaked onto her jacket. The air grew thicker, heavier, carrying scents of incense and something metallic that stung her nostrils. Blood. Recent. A faint green light appeared at the end of the tunnel. Not streetlight. Something wrong. Quinn slowed, torch sweeping the floor. A small bone token lay discarded near the threshold, carved with symbols that hurt to look at directly. She hesitated only a second before scooping it up. Evidence. Or invitation. She stepped through. The abandoned Tube station unfolded like a fever dream beneath Camden. The Veil Market. She'd heard the name in hushed interrogations, dismissed it as urban legend. Now it pressed against her from all sides. Stalls constructed from salvaged metal and faded velvet lined the old platforms. Strange lanterns hung from the curved ceiling, casting sickly amber light that seemed to writhe. Figures moved between them, hooded, masked, some clearly not entirely human. The air hummed with low conversation in languages that didn't belong in London. Her military bearing kept her spine straight even as her stomach clenched. Rain still dripped from her coat onto the dusty platform. She scanned the crowd, searching for that distinctive curly hair, the Saint Christopher medallion that would catch the light. "There." She spotted him twenty metres away, weaving between a stall selling vials of glowing liquid and another displaying what looked like preserved eyes in glass jars. He kept glancing back, face tight with something beyond fear. Recognition, perhaps. Quinn moved after him, torch now switched off and returned to her belt. Better to blend. The market's inhabitants parted around her like water around stone. A few stared too long. She met their gazes without flinching. Her sharp jaw tightened. Let them look. She had questions that needed answers. Herrera ducked behind a towering bookshelf that seemed out of place even here. She quickened her pace, hand hovering near her concealed weapon. The bookshelf swung inward as she approached, revealing a hidden room beyond. Clever. Like the one at The Raven's Nest. These people loved their secrets. She pushed through before it could close. The secret room smelled of aged paper and candle wax. Maps covered the walls, similar to those in Silas' bar but marked with routes that shifted when she wasn't looking directly at them. Black-and-white photographs showed people who appeared in multiple images despite wearing different clothes across decades. A single desk dominated the centre, cluttered with leather-bound ledgers. Herrera stood behind it, breathing hard. His warm brown eyes met hers across the space. The scar along his left forearm stood out pale against his olive skin as he gripped the desk edge. "You shouldn't have followed me here, Detective Quinn." His accent carried traces of Seville, softened by years in London. The words came measured, each one weighed before release. No panic. That unsettled her more than flight would have. She closed the door behind her. The bookshelf clicked back into place with finality. "Tomás Herrera. Or do you prefer Tommy when you're stitching up things that bleed black?" A muscle twitched in his cheek. "Names have power down here. Best not throw them around." "Power." She stepped closer, boots leaving wet prints on the stone floor. "That's what this is about, isn't it? Your little clique. The treatments you lost your license for. The patients who aren't patients at all." He reached up slowly, fingers brushing the Saint Christopher medallion at his throat. Protection for travellers. She wondered who he truly travelled with these days. "You lost someone." His voice dropped lower, almost gentle. Too gentle for a suspect. "Three years back. DS Morris. The reports said unexplained circumstances." "Don't." The word cracked like a whip. Quinn's hand tightened into a fist at her side. Rainwater trickled down her neck, cold as memory. "You don't get to say his name." Herrera didn't flinch. "I treated him that night. After. When the others wouldn't." The room seemed to shrink around them. The lanterns on the walls flickered though no breeze stirred. Quinn's mind raced through the file. Morris had been found in an alley not dissimilar to the one above, throat torn but no blood at the scene. Like it had been drained elsewhere. Or never there at all. "Lies." She advanced another step. "You were nowhere near that case." "Wasn't I?" He lifted his left arm, scar gleaming in the low light. "Knife attack, they called it. But we both know different. Same night your partner died. Same shadows moving in the same streets." Her brown eyes narrowed. Military precision kept her from lunging across the desk. Barely. "What are you selling here, Herrera? Information? Or absolution?" He smiled then, small and tired. "Neither. Just survival. For people like your Morris. For people like me who saw too much." The hidden door rattled suddenly. Voices from the market filtered through, agitated. Someone shouted about intruders. Quinn's head snapped toward the sound before returning to him. "You led me here deliberately." "Not deliberately." His fingers drummed once on the ledger. "But I stopped running when I could have lost you in the tunnels. Different thing." "Why?" "Because some questions need asking." He pulled open a drawer, removing a small black notebook. "And some answers need witnessing." The rattling grew louder. Wood splintered. Quinn drew her weapon, keeping it lowered but ready. The room's air thickened further, pressing against her skin like a living thing. The photographs on the walls seemed to watch them now, faces turned in their direction. Herrera slid the notebook across the desk. "Morris's final report. The real one. Not what they put in the official file." She didn't touch it. Not yet. "And the price?" "No price." His warm brown eyes held hers, steady. "Just a warning. What killed him isn't finished. It's been watching you too, Detective. Following the same threads you're pulling." The door burst open behind her. Three figures filled the frame, faces obscured by hoods. One held a bone token similar to the one in her pocket, but this token glowed with inner fire. The lead figure pointed directly at her. "Met copper. No token. She doesn't belong." Herrera moved faster than she expected, rounding the desk to stand beside her. His shoulder brushed hers, solid and unexpectedly reassuring. "She has the token." His voice carried authority now, short sentences clipped with emergency-room efficiency. "Show them." Quinn produced the carved bone from her pocket. It felt warmer than before. The figures hesitated, conferring in whispers that sounded like dry leaves scraping concrete. The leader lowered his hand. "Market law says she leaves at first light. No earlier. No later." They retreated, the bookshelf swinging shut once more. Silence descended, broken only by the distant hum of the market beyond. Quinn turned on Herrera, weapon still in hand though not raised. "Explain." He gestured to the notebook. "Read it. Then decide if you still want to arrest me for whatever you think I've done." She holstered her weapon but kept her distance. The notebook's cover felt like real leather, soft from handling. When she opened it, Morris's familiar scrawl filled the first page. Her partner's handwriting. Undeniable. Dated the night he died. Her throat tightened. "How did you get this?" "Same way I got the scar." Herrera touched his forearm again. "Wrong place, right time. Or maybe right place, wrong time. Depends who you ask." Quinn flipped pages, absorbing dates and codes and references to entities she couldn't begin to understand. One entry made her freeze. Her own name appeared, listed under potential assets. Morris had been watching her too. Protecting her, perhaps. "You treated him." She didn't look up. "After." "Best I could." His words came quieter now. "He asked for you. At the end." The room's lanterns dimmed suddenly. The maps on the walls rippled as if touched by invisible wind. Quinn snapped the notebook shut, gripping it tight enough to whiten her knuckles. "What killed him?" Herrera moved to the far wall, pressing a specific spot on one of the maps. A section slid aside, revealing a narrow tunnel descending further into darkness. "Same thing that's been killing others in your city. Same thing that will come for you if you keep digging alone." She stepped closer to the tunnel's mouth. Cold air breathed from below, carrying the copper scent again. Stronger now. The market's noises had faded completely. Only the two of them remained in this strange sanctuary. "You could have run." Her voice held new edges, suspicion mixed with something dangerously close to trust. "Lost me in the tunnels like you said." "I could have." He joined her at the tunnel entrance. His Saint Christopher medallion caught the lantern light, glinting. "But your partner trusted me with something before he died. A message for you specifically." Quinn's head turned sharply. "What message?" Herrera's warm brown eyes held a depth that made her reconsider everything she thought she knew about the man. His scar seemed to pulse with old pain. "'Tell Harlow the shadows have her name now. And they collect their debts in full.'" The tunnel stretched before them, descending into unknown territory. Quinn weighed the notebook in her hand against the weapon at her hip. The market above would close its doors at first light. Whatever hunted in these depths clearly didn't follow the same rules. She took the first step down. Herrera followed close behind. "Careful where you place your feet, Detective. Some stairs here don't lead where they should." The darkness swallowed them both as the hidden panel slid shut above, cutting off the last traces of amber light. Only the sound of their footsteps remained, and the growing certainty that whatever waited below had been waiting for her specifically. A low growl echoed from ahead. Not animal. Not quite human. Quinn's grip tightened on her torch. "Stay behind me." "With respect," Herrera whispered, voice carrying the precise cadence of a man who'd seen too many impossible patients, "you might want to reconsider that order." The growl came again. Closer this time. Something scraped against stone, claws or scales or both. Quinn clicked on her torch. The beam revealed movement at the tunnel's end, a shape that defied easy description. Multiple limbs. Eyes that reflected light wrong. It knew her name somehow. She felt it in her bones. "Back the way we came," she ordered, already turning. But the panel above had vanished. Only seamless wall remained. Herrera's hand found her elbow in the darkness. "Too late for that now." The thing in the tunnel spoke with Morris's voice, twisted through too many teeth. "Harlow. You came." Quinn raised her weapon, heart hammering against her ribs. The notebook suddenly felt like it burned in her other hand. "What the hell are you?" The creature laughed, a sound like wet paper tearing. "Your partner. What's left of him. The shadows kept the best parts." Herrera pulled her backward as the thing advanced. His medallion swung wildly. "Run, Detective. I'll slow it down." She didn't run. Instead she planted her feet, military precision meeting supernatural horror head-on. Rainwater from the streets above still clung to her coat, mixing now with fresh sweat. "No one's slowing anything down." Her voice echoed strangely in the confined space. "Not until I get answers." The creature wearing Morris's stolen voice lunged forward, all teeth and memory and wrongness. Quinn fired. The shot deafened in the tight tunnel. Herrera shouted something in rapid Spanish. The thing kept coming. She fired again. And the underground market far above them trembled as something ancient stirred in response to the violence below.
