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>

“Stop, police!” Detective Harlow Quinn vaulted the bonnet of a stalled cab and landed hard enough to jar her teeth. Her shoes skidded on the slick road. A horn blared beside her, close and ugly, and the driver punched the glass with his palm as she cut across the lane. The suspect did not stop. He tore through the traffic with a black hood plastered to his skull, one hand clamped to his ribs, the other clutching a small bone-coloured disc. Thin, fast, limping but not slowed by it. He moved like pain had learned to keep up with him. Quinn drove forward. A bus hissed at the kerb. Headlights smeared across wet tarmac. Someone shouted as she shouldered through a knot of theatre-goers under cheap umbrellas, all perfume, gin breath, and damp wool. One man grabbed at her sleeve. “Oi, watch it!” She twisted free, flashed her warrant card without breaking stride. “Met Police. Move.” That worked on most people. Not on the suspect. He glanced back once, pale cheek under the hood, eyes bright as a fox caught in bins. Then he hooked left into a narrow lane behind a row of restaurants. Quinn followed. The lane swallowed the traffic noise and spat back other sounds, dripping gutters, the rattle of extractor fans, the scrape of crates under a kitchen boy’s hands. Steam rolled from a back door, thick with garlic, burnt butter, and bleach. The suspect kicked over a stack of blue plastic bins. Quinn hit the first bin with her thigh, vaulted the second, and slammed her shoulder into the wall to keep from going down. Pain flashed clean and white. Her worn leather watch scraped brick. “Enough.” The suspect reached the far end of the lane and threw a look over his shoulder. Not panic now. Calculation. He knew the route. Quinn knew that look. Runners always split in two at the eyes before the body chose a direction. He went right. She came out behind him onto a wider street where the pavements shone black beneath the shopfront lights. Soho still throbbed around them, even at this hour, even under rain that needled faces and ran down collars. A kebab shop glowed with harsh white strips. A corner off-licence had barred windows and a tired little sign offering phone repairs, Polish lager, and dreams at discount prices. Two women stood beneath its awning sharing a cigarette, their laughter cutting off as Quinn sprinted past. The suspect barged into a man carrying takeout coffees. Cups burst. Hot liquid splashed across the pavement. “Jesus!” “Move him!” Quinn barked at no one in particular. No one moved him. London loved a spectacle more than duty. She gained three strides when he faltered at the mouth of another street. His left foot dragged. A dark stain spread under his hand at his ribs. Blood, or something close enough to blood to count. He had come out of The Raven’s Nest ten minutes ago, fast and wrong. Quinn had watched from the opposite pavement while the green neon sign buzzed above the bar’s entrance, staining the rain a sickly colour. She had sat in her unmarked car with cold coffee in the cup holder and a file on her passenger seat, photographs, bank transfers, missing persons reports, and one blurred CCTV image of that same hooded man entering the bar two nights before a dealer turned up folded inside a church confessional. The Raven’s Nest looked like a place built from secrets. Old maps covered the walls inside. Black-and-white photographs watched the drinkers from every angle. Quinn had been in once with a warrant that dissolved into legal smoke by morning. The owner had smiled as if he had sold the judge the match. Tonight, the hooded man had stumbled out of the Nest clutching the bone token. Then he had seen Quinn. Now he cut across the road towards a locked gate beside a shuttered music shop. Quinn reached for her radio. “Control, Quinn. Foot pursuit from Soho northbound, suspect male, black hoodie, possible stab wound, carrying evidence. Heading towards Charing Cross Road, I need units to box in—” The radio crackled, spat, and died. Not lost signal. Killed. She looked down at it, then up at the suspect. He had stopped at the gate. No keypad. No visible lock. He pressed the bone disc against the rusted chain, and the chain slackened like a cut tendon. Quinn slowed for half a second. The gate opened onto a set of service steps dropping beneath the pavement. The suspect vanished down them. “Bollocks.” She reached the gate and caught it before it swung shut. The metal felt warm despite the rain. A smell breathed up from below, old dust, copper, wet stone, incense, engine oil, and something sweet that made her tongue prickle. The service stairwell should have led to a basement under the music shop. It did not. It sank too far. Quinn unclipped her baton, thumbed her radio again, and listened to dead air. “Control, receiving?” Static crawled. She shoved the radio back into her coat and descended. The steps twisted in a tight square spiral. Her soles slapped concrete. The rain noise faded above her until London became a memory of tyres and sirens. Graffiti crowded the walls at first, tags, football abuse, a crude crown above the word RAVEN. Then the paint changed. Symbols etched into the concrete with a steady hand. Some looked like letters seen through water. Others hurt to follow. Quinn kept her eyes on the suspect’s blood. Drops marked the stairs at uneven intervals, dark against grey. He had rushed. Good. Injured men made mistakes. At the bottom, a tiled corridor stretched ahead beneath a low arched ceiling. Old Underground tiles, cream and bottle green, cracked but clean. A dead station sign hung crooked on the wall. CAMDEN ROAD, one arrow said, though the real station did not sit anywhere near Soho. Another sign had lost half its letters and now read MIND THE G. The suspect staggered through a circular iron door at the end. Noise rolled out. Voices. Dozens. Hundreds. Trading, arguing, laughing. Metal clinking. Glass chiming. Something alive screeching from inside a cage. Quinn approached the door. The bone token had opened it for him. She had no token, unless she counted evidence still in the suspect’s hand. The iron door stood open by a hand’s width, closing with slow, hydraulic spite. She slipped through sideways just before it sealed. The underground market unfolded in a dead Tube station beneath Camden, or under something wearing Camden’s bones. Quinn stopped with her back to the iron door. The old platform had become a long bazaar. Stalls lined both tracks, each lit by mismatched lamps, oil flames in red glass, buzzing bare bulbs, blue jars that held tiny spinning lights. Tattered awnings hung from iron ribs. The air pressed thick against her face. It tasted of cardamom, rust, hot wax, damp fur, and frying meat from a source she did not care to name. People moved everywhere. Some looked ordinary. Coats, boots, tattoos, umbrellas dripping into the gaps between sleepers. Others did not bother. A woman with silver scales along her throat counted coins with six fingers. Two men in immaculate suits held a conversation without moving their mouths. A child-sized thing in a flat cap dragged a sack that twitched and muttered. Quinn’s hand tightened around the baton. A hidden supernatural black market, she thought, though no sane report would ever accept those words. DS Morris would have laughed once. Then he would have gone quiet. A memory jabbed at her, Morris on a wet concrete floor three years ago, mouth open, eyes wide, no wound on him, his shadow burned into the wall behind him like Hiroshima glass. No. Quinn shut the door on it. The suspect shoved through the crowd ahead, one hand still clamped to his side. He passed beneath a hanging sign made from vertebrae and copper wire. The letters shifted until Quinn understood them. THE VEIL MARKET. She moved after him. A broad man stepped into her path, naked to the waist beneath a butcher’s apron. His skin had the waxy look of old mushrooms. Hooks hung behind him with strips of meat threaded through them, red, blue, black, pearly white. One strip pulsed. “Token?” Quinn held up her warrant card. “Police.” The butcher stared at it. His eyes had no whites. “Token.” “Move.” He smiled, showing little square teeth filed flat at the ends. “Wrong market for badges.” Quinn struck his knee with the baton. The joint cracked sideways. He dropped with a roar that shook jars on the stall. Quinn drove an elbow into the bridge of his nose as he fell, then stepped over him before the crowd decided whether to admire or kill her. “Met Police,” she shouted. “Clear the way.” A ripple passed through the market. Not fear. Interest. That worried her more. The suspect heard the shout. He looked back, saw her, and panic returned to his face. He plunged down from the platform onto the old track bed, scattering a flock of pale beetles the size of pound coins. Quinn followed, landing between rails filmed with grease. Her ankle turned on loose ballast. She caught herself against a pillar wrapped in prayer ribbons and old Oyster cards. A woman at a stall hissed as Quinn brushed past a tray of stoppered vials. “Careful with those, darling. One breaks and you spend Christmas as a staircase.” “Complain to the council.” “Which one?” Quinn vaulted onto the opposite platform. The suspect ducked into a narrower passage under an arch marked STAFF ONLY. Someone had painted a newer warning beneath it in red. NO REFUNDS BEYOND THIS POINT. Quinn slowed at the threshold. The passage beyond lacked stalls. Its walls sweated. Pipes ran overhead, thick as thighs, knocking with pressure. The floor sloped down into gloom broken by green lamps. The suspect’s blood marked the tiles. Her radio gave a single pop. “Quinn?” A voice thinned by static. “Quinn, respond. Where the hell are you?” She snatched it up. “Underground. Disused station beneath Camden, possibly connected to Soho service access. Suspect heading deeper. Send armed support and British Transport Police.” Silence. Then Detective Inspector Vale’s voice cracked through, distorted. “Your GPS places you in Leicester Square.” “Then your map’s lying.” A burst of shrieking feedback made her flinch. Another voice slid through the static, not Vale’s. Male. Familiar in shape, impossible in fact. “Harlow.” The radio slipped in her damp hand. Morris. Not a recording. Not memory. The same tired Welsh edge. The same swallow before her name. “Harlow, don’t come down here.” The channel snapped dead. Quinn stared at the radio for one hard second, then smashed it against the wall. Plastic burst. Batteries skittered across the tiles. A few shoppers nearby pretended not to watch. She looked back towards the main market. Safety, if that word had any rights here, lay through the crowd, up the false stairs, back to wet streets and sane paperwork. She could seal the gate. Call in a cordon. Return with numbers, cameras, rifles, warrants signed by men who would later deny their own signatures. The suspect coughed somewhere down the staff passage. Wet. Weak. Then came another sound. A lock clicking. Quinn advanced. The passage bent twice, each turn tighter than the last. The market noise faded behind her, replaced by drips, pipe knocks, and the soft slap of the suspect’s shoes ahead. Her watch ticked against her wrist, absurdly steady. The corridor opened into an abandoned ticket hall lit by old green lamps. The ceiling arched high above, blackened by soot. Ticket windows lined one wall, their brass grilles stuffed with feathers, teeth, and folded notes. The tiled floor bore a circular mosaic at its centre, a compass rose with the north point chipped out. The suspect stood across the hall before a lift with no doors. His hood had fallen back. He looked younger than Quinn expected, early twenties, perhaps, with a shaved head and a face gone grey from blood loss. His right hand held the bone token. His left pressed a folded packet under his jacket. “Drop it.” He flinched, then raised the token. “Stay back.” Quinn lifted the baton. “Bad choice of threat.” “You don’t know what this is.” “I know you ran from a murder enquiry carrying it.” “Murder?” He laughed, then groaned and bent at the waist. Blood splashed between his trainers. “That’s what he told you? Course he did. Silas feeds the police scraps and you lick the plate.” Quinn stepped closer. “Name.” “Ask your bar friend.” “I’m asking you.” He drew himself up with effort. His lips had taken on a bluish cast. “Eli.” “Packet on the floor, Eli.” “No.” The lift shaft behind him breathed cold air into the hall. Something moved below, far down. Metal dragged over metal. Quinn shifted left, cutting off his angle to a side passage. “You’re bleeding out. I can get you help.” “From who? Your people? His people?” “There’s a difference.” “Not down here.” A voice sounded from the ticket windows. “He is not wrong, Detective.” Quinn turned without turning her back fully. Tomás Herrera stood behind one of the brass grilles, half in shadow, half in green light. Short curly dark brown hair clung damply to his forehead. Olive skin. Warm brown eyes that flicked from her baton to the suspect’s wound with clinical speed. A Saint Christopher medallion rested at his throat, bright against a dark shirt. His sleeves sat rolled to the elbow, exposing the long scar along his left forearm. She knew him from files and two failed interviews. Former paramedic. Struck off. Too many patients who should have died, too many bodies that never reached NHS records. “Tomás Herrera.” “Detective Quinn.” “You picked a strange place to run a clinic.” “Rent upstairs is murder.” “Step away from him.” Tomás looked at Eli. “He will die in minutes.” “He can do that in custody.” “No, he cannot. Custody has fluorescent lights and vending machines. He has a claw wound near the liver and venom in the blood. Your custody sergeant has plasters.” Quinn’s jaw tightened. “Packet first.” Eli shook his head. Tomás raised both hands, palms out. “Listen to me, cariño, whoever pays you, they underpaid. Give her the packet or she breaks something you still need.” Eli’s eyes darted to the empty lift shaft. “He said if I hand it over, they’ll find my sister.” Quinn caught that. “Who said?” Eli swallowed. From the hall behind Quinn, footsteps approached. Not rushed. Measured. Military, almost. She glanced towards the passage she had entered through. Three figures appeared under the arch. Men in dark coats, dry despite the damp air. Their faces looked ordinary until they passed beneath the lamp. Then Quinn saw the mouths. Too wide. Teeth tucked behind lips like folded knives. The market beyond had gone quiet. Tomás swore under his breath in Spanish. Quinn did not lower the baton. “Friends of yours?” “Not since they stopped needing stitches.” The centre man smiled. “Detective Harlow Quinn. Eighteen years in service. Commendation for bravery, Tower Hamlets. Commendation for conduct, Brixton. Partner deceased, case unresolved.” Her grip changed on the baton. He noticed. His smile deepened. “We can resolve things.” Eli whimpered. “See? See, they know.” The man extended a gloved hand. “The packet, boy.” Quinn stepped between them and Eli. “You’re interfering with a police investigation.” “Police?” The man tasted the word. “Down here, that is a costume.” Tomás moved from behind the ticket window through a narrow staff door, carrying a battered black medical bag. “Harlow, this is the part where pride gets people opened.” “You call me Detective.” “Then detect. Three of them. One of you. One dying thief. One disgraced medic with a bag of needles and bad choices.” “Needles work?” “On men, yes.” The three figures advanced. Quinn drew her extendable baton to full length with a sharp snap. The centre man’s eyes slid to it. “How quaint.” Quinn threw the broken radio at his face. He caught it by reflex. She drove forward. The baton cracked across his wrist. Bones gave under the strike, or whatever passed for bones. He snarled. Quinn pivoted and stamped into the knee of the man on the left, then ducked as the third slashed at her face with fingers that had become hooked black claws. A claw grazed her cheek. Heat opened along the cut. Tomás moved fast for a medic. He jammed a syringe into the left man’s neck and thumbed the plunger. The man stiffened, every muscle locking at once, and toppled like a felled statue. “Works on men,” Quinn snapped, blocking another strike. “I rounded up.” Eli staggered towards the lift shaft. “No!” Quinn shouted. He pressed the bone token to the empty air. The shaft lit from within. Not with light, exactly. With depth. A vast dark space opened where the lift should have been, and wind roared upward carrying screams, market bells, and the stink of river mud. The centre man recovered and lunged past Quinn straight for Eli. Quinn caught his coat with one hand and drove the baton into his throat with the other. He choked, folded, then slammed his forehead into hers. White sparks burst across her vision. She hit the floor on one knee. Her palm landed in Eli’s blood. The centre man stepped over her. Tomás shouted something in Spanish and hurled a glass vial. It shattered against the man’s shoulder. Blue fire crawled over his coat. He screamed, more angry than hurt, and spun towards Tomás. Eli stood at the edge of the open shaft, packet in one hand, token in the other. Quinn forced herself up. “Eli, look at me.” His eyes found hers. Huge. Childish now. “Your sister’s name.” His mouth trembled. “Mara.” “I can help Mara. But not if you jump.” The centre man, burning blue, laughed through clenched teeth. “She already jumped.” Eli made a sound no man should make. He opened the packet. Something inside unfolded, black and thin and frantic, like a living shadow cut into strips. The green lamps burst one by one. The mosaic compass cracked across its missing north point. Tomás grabbed Quinn’s arm. “Detective, down!” The thing in Eli’s hand screamed with Morris’s voice. Then every door in the ticket hall slammed open at once.
