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 there, black coat!”
Detective Harlow Quinn vaulted the
bonnet of a stalled minicab and landed hard enough to send pain up both shins.
The suspect cut left through
the knot of bodies outside a kebab shop, one hand clamped over his ribs, the other clutching a small ivory disc. Bone token.
Quinn had seen it flash
when he shoved a woman into traffic and sent a delivery cyclist skidding across the wet road. Not plastic. Not poker chip. Bone, carved with marks that hooked at the eye and refused to settle into any alphabet she knew. “Police! Move!”
A man in a cheap
navy suit turned too late.
Quinn caught him by the
shoulder, spun round him, and kept running. Her coat snapped behind her. Water sheeted off awnings.
Taxi horns blared in a
foul brass chorus.
Somewhere behind her, uniformed boots
slapped the pavement, but they had fallen back after the second crossing. The suspect knew the alleys. Quinn knew men who ran.
He crashed through a stack
of empty crates outside a grocer’s
, recovered
without looking down, and took the passage beside a shuttered pawnbroker. Quinn followed.
The alley narrowed to a
slick brick throat, bins crowding both walls, their lids trembling under the rain. Sour beer, old fish, diesel, and wet cardboard thickened the air.
Her left shoulder clipped a
rusted drainpipe.
The worn leather watch on
her wrist scraped brick. “Met Police,” she barked. “Last warning.”
The man answered by kicking
a bin over. Quinn hurdled it.
Her shoe came down in
rotten fruit, slid, caught.
She used the wall, palm
flat against grit and slime, and drove herself on.
Her lungs burned in a
clean, useful way.
Her old instructor’s voice would
have called it pace discipline.
Her dead partner Morris would
have called it bloody-mindedness. At the end of the alley, the suspect shouldered through a service door hanging open behind a corner shop. Quinn caught a blur of fluorescent light, shelves of tinned tomatoes, prayer beads, cigarette papers, then a woman’s shriek as he burst through the shop and out the front. Quinn followed through the wreckage. A bell above the door jangled without rhythm. “Back room locked?” she snapped at the shopkeeper, who stood behind the counter with both hands raised and a cricket bat within reach. “Who is that man?” “Bad answer.”
She slammed through the front
door before he found another. Camden High Street sprawled ahead, glazed black and gold under shop signs and headlights. The suspect crossed against traffic, limping now. Good. Quinn had clipped him with the taxi door back near Mornington Crescent.
He had speed, but damage
changed the arithmetic. A double-decker bus roared between them. Quinn hit the wet road, one hand up as if palm and badge could stop two tonnes of red steel. The bus driver leaned on the horn.
She slipped past the grille
with inches to spare and heard a passenger call her mad through the glass. The suspect glanced back. That was his mistake. Quinn saw his face under the hood, pale, narrow, rain dripping from a broken nose. Not fear. Recognition.
His eyes snagged on her
like he knew exactly who hunted him.
Then he vanished down the
steps of a disused Tube entrance that should have had a locked gate across it. Quinn stopped at the top. The old station entrance hunched between a tattoo parlour and a late-night bakery, its tiled
facade
split by grime and age. A faded Underground roundel had lost half its red enamel. Someone had bolted a corrugated metal gate over the stairwell, but the padlock hung open, neat as an invitation. Beyond it, tiled steps descended into dark that breathed warm air and dust. Behind her, London kept moving. Buses hissed. Drunk voices rose and broke. Rain rattled on shopfronts. Ordinary noise, ordinary danger. Below, a different sound drifted up. Coins. Many coins. Low voices. A goat bleating once, sharp and offended. Quinn drew her baton. “Control, Quinn. Suspect entering abandoned Tube station, Camden High Street, north side, old entrance beside a bakery. Request immediate support.” Static chewed her ear. “Control, do you receive?” Nothing. The radio gave one low click, then died. Quinn looked at the black mouth of the stairwell.
Her reflection wavered in the
wet tile beside it, cropped salt-and-pepper hair plastered to her skull, brown eyes flat, sharp
jaw clenched
tight enough to ache. Forty-one years old, eighteen years in, and every bad choice still wore the same face. Morris had gone through a door without waiting for her. They found no body.
Only blood on broken concrete
and his phone ringing from inside a wall. Quinn gripped the baton until her fingers steadied. “Not tonight.” She went down. The first flight stank of piss and wet stone. The second shed the city like old skin. By the third, the air warmed. Candle smoke replaced exhaust. The tiles changed as she descended, white ceramic giving way to cracked green mosaics, then to brick marked with fresh chalk symbols. Some looked like warnings. Some looked like teeth. A turnstile blocked the bottom landing. The suspect stood beyond it, hunched and panting, one hand on a tiled column.
He shoved the bone token
into a narrow brass slot fixed to the wall. The slot swallowed it with a wet click. A gate opened where no gate had been. Quinn saw a glimpse beyond him, lanterns, tarpaulin roofs, hunched stalls, faces turning. A whole hidden concourse stretched under Camden, built inside an abandoned station that had not appeared on any active survey she had ever read. Its platforms had become aisles. Its tracks lay boarded over. Black market, her mind supplied, before common sense could slap the words away. The suspect gave her a thin smile. “Wrong stairs, Detective.” He slipped through. Quinn lunged. The brass gate
began to
close. She jammed her baton into the gap. Metal screamed. The pressure bit down, bent the baton into a shallow bow, and stopped with three inches to spare. Something on the other side hissed. A stallholder with blue lips and a
velvet
cap peered over a display of bottled lights. Beside him, a woman whose veil moved like smoke held up a hand of too many fingers. Quinn did not blink. Blinking conceded ground. “Open it.” The blue-lipped man clicked his tongue. “Market rules, copper. Token or toll.” Quinn shoved her warrant card through the gap. “This is my toll.” The man leaned close, studied it, and laughed hard enough to cough sparks. “That gets you a queue at a magistrates’ court. Not through Camden Below.” Quinn forced the gate another inch with her shoulder. Pain flared where the metal dug into her collarbone. The suspect had slowed ahead, swallowed by the crowd but not gone. Black coat. Blood at the ribs. Limp favouring the right leg. “Name your toll.” The veiled woman’s head tilted. “Memory.” “No.” “Blood.” “No.” “Name, then.” Quinn looked at the closing gate, at her bent baton, at the fleeing suspect, and at the impossible market humming beyond.
Somewhere down there sat answers
men had killed to keep.
Somewhere down there a carved
bone token opened a door London denied existed. “Quinn.” The blue-lipped man’s smile faded. “Full.” “Detective Harlow Quinn.” The brass slot spat out a strip of paper the colour of old skin. Her name wrote itself across it in wet black letters. The gate released her baton and opened. The veiled woman folded the strip into her sleeve. “Mind how you spend yourself, Detective Harlow Quinn.” Quinn stepped through and drove her shoulder into a man carrying a cage of white rats with human hands. “Police. Move.” The market noticed her properly then. Every head turned in stages. Human faces. Almost human faces. One child with antlers held a sugared plum and stared with amber eyes. A butcher in a stained apron chopped something that sang on the block. Glass jars lined a nearby stall, each filled with pale worms coiled around labels in Latin. Charms dangled from wires overhead, brass, bone, tin, and teeth. Their soft clack-clack-clack merged with the murmur of bargaining. The old Tube signs remained behind it all, ghosts of civic order. NORTHBOUND pointed toward a corridor filled with crimson lamps. WAY OUT hung above a brick wall. MIND THE GAP had
been painted
on the platform edge in fresh white letters, though no train had run there for decades. The suspect shoved through a stall selling folded maps that shifted when touched. Quinn pushed after him. “Black coat! Stop him!” No one helped. A few laughed. One vendor swept his wares closer, as if she carried plague in her warrant card. The suspect grabbed a hanging string of charms and yanked it down behind him. Beads and little finger bones scattered across the planks. Quinn’s shoe rolled on one. She hit a stall shoulder-first. Bottles toppled. Thick yellow smoke burst across her face. Her eyes streamed. Bitter almond coated her tongue. “Careful!” snapped the stallholder, a small, bald man with silver nails hammered through both ears. “That’s dream-rot, imported!” “Send an invoice to Scotland Yard.” “Address?” Quinn kicked through the smoke and nearly struck a girl carrying a bowl of black water. The surface reflected stars, though no sky sat overhead. The girl hissed at her. Ahead, the suspect climbed onto the boarded track and dropped between two rows of stalls. Quinn followed, boots thudding on old sleepers under cheap plywood. The underground market swallowed sound badly. Footsteps doubled. Voices came from wrong angles.
Somewhere, a bell rang three
times and a dozen stallholders covered their eyes. “Tommy said no police in the Market.” The name cut through the noise. Quinn turned. A man stood half inside a canvas medical booth, holding a blood-soaked gauze pad in one gloved hand. Late twenties. Olive skin. Short curly dark brown hair damp at the temples. A Saint Christopher medallion flashed at his throat. His left sleeve had ridden up, revealing a scar along his forearm, pale against skin. Tomás Herrera. Quinn knew him from three files and no convictions. Former paramedic. Lost his licence. Seen near too many crime scenes involving victims who recovered before ambulances arrived. He held her gaze, warm brown eyes narrowing. “Detective Quinn. You’re a long way from your paperwork.” She kept moving, but angled close enough to speak. “Black coat. Broken nose. Bleeding from the ribs.” Tomás looked past her, jaw tightening by a fraction. “Half the Market answers to that on a bad Saturday.” “He killed a witness in Soho.” That landed. His gloved fingers curled round the gauze. “Witness to what?” “You first.” A crash broke across the concourse. The suspect had overturned a table of metal masks. They hit the boards with a ringing clamour that set several lamps swinging. Tomás
flicked
his eyes towards the sound. “Don’t follow him to the lower platforms.” “Why?” “Because people who charge down there come back wrong, if they come back noisy enough to count.” Quinn moved. Tomás caught her sleeve. Not hard.
Just enough to leave blood
on the cuff. “Listen to me. This place has rules. You don’t have friends here.” Quinn looked at his hand until he removed it. “Then keep up.” His mouth tightened. “No chance, Detective. I’m not your constable.” “Good. Constables need forms.” She ran. The suspect disappeared beneath an iron sign that read PLATFORM 3 in chipped white paint. Quinn passed beneath it and left the main market’s fever behind. The passage dropped lower, tiled walls sweating mineral damp. Stalls thinned. Goods changed. Less jewellery, more knives. Less chatter, more watching. A woman with a face full of pins weighed grey powder on brass scales. Two men in matching brown coats argued over a jar containing a blinking eye. The smell shifted too, cloves, hot metal, old blood. Quinn heard Tomás behind her despite his protest. His breath came steady. Former paramedic. Fit enough. Foolish enough. “Thought you weren’t my constable.” “I’m here for whoever you get killed.” “Start with him.” The suspect hit the end of the corridor and swiped another token against a black door set into the wall. This one did not open at once. He slammed his palm flat against it. “Come on.” Quinn closed the distance. Twenty feet. Fifteen. He turned and threw something. Tomás shouted a word in Spanish that needed no translation. The object struck the floor between them, a small glass bulb wrapped in copper wire. It
shattered
without a bang. Darkness erupted. Not absence of light. A living black mass punched outward and filled the corridor, thick as ink, cold as river mud. Quinn threw an arm over her face and felt it crawl across her skin. Her ears filled with whispers. Not words at first. Then fragments. Harlow. Left him. Morris called. She drove forward instead of back. Her shoulder hit tile. Her baton found air. Her left hand found Tomás’s coat and shoved him behind her before the darkness could split them. “Wall. Left side. Move.” “I know how to walk blind.” “Then do it faster.” Something brushed Quinn’s cheek. Fingers, long and wet. She struck with the baton. The blow met softness, then a crack like a crab shell under a boot. A shriek tore through the dark. The whispers broke into furious muttering. Tomás’s hand closed over her wrist. “Low step.” She felt it a heartbeat later, the floor dropped where old stairs began. They descended together, one hand on slime-slick tile, the other ready to strike. The blackness thinned with each step until a dirty red glow bled through. They emerged onto Platform 3. The lower platform had no stalls, not in the usual sense. It held cages, curtained booths, and chained lockers bolted to the old tunnel wall. Candles guttered in niches. The track ahead vanished into a round black tunnel marked with sigils scratched over older service numbers. A low
mechanical
thump
pulsed
somewhere beyond, steady as a diseased heart. The suspect stood at the platform edge, one hand pressed to his ribs, the other raising a curved little old black iron knife to his own throat. Quinn stopped ten feet away. “Put it down.” He laughed. Blood painted his teeth. “You don’t even know what you chased.” “I know you stabbed Elian Voss behind The Raven’s Nest.” At the mention of the bar, his face twitched. The Raven’s Nest, Soho. Green neon above the entrance. Old maps and black-and-white photographs on the walls. Quinn had stood in that dim back room two hours earlier, watching Tomás’s prints dry in blood beside a dead informant who had promised her names. Tomás went still at her shoulder. “Elian’s dead?” The suspect’s eyes jumped to him. “Tommy. Still patching monsters and calling it mercy?” Tomás took one step forward. “You were at the Nest.” “Everyone was at the Nest. That’s where rats go when the water rises.” Quinn shifted left, cutting off the tunnel. “Knife down. Hands where I can see them.” The suspect pressed the blade deeper. A red line opened under his jaw. “Arrest me and they’ll peel your station apart. Follow me and they’ll do worse. Either way, Detective, you’re three years late.” Morris moved through the space between words. Quinn’s grip tightened on the baton. “What did you say?” The suspect smiled as if he had found the bruise. “DS Morris screamed longer than they expected.” Tomás muttered, “Madre de Dios.” Quinn crossed the last ten feet. The suspect slashed, not at himself, at her face. She leaned back. The blade kissed the air below her eye. She struck his wrist. Bone cracked. The knife spun onto the platform. He drove his broken nose into her cheek, a savage headbutt that burst white pain behind her eyes. She staggered one step. He slammed both hands into her chest. Quinn fell off the platform. Tomás caught her coat with both hands. The fabric tore. Her boots scraped empty air above the track pit. Below, something moved in the darkness between the rails, large enough to make the sleepers groan. Tomás’s scarred forearm strained as he hauled her upward. “Quinn!” The suspect scooped up the black iron knife with his good hand and ran for the tunnel. Quinn got one knee onto the platform. Behind them, the gate to Platform 3 slammed shut. Every candle went out. From inside the tunnel, the suspect screamed, and something screamed back in his voice.
