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!”
The man in the charcoal
hoodie cut across the road without looking. A taxi locked its brakes, horn blaring, and missed him by inches.
Detective Harlow Quinn vaulted the
bonnet with less grace and more intent, boots skidding on the slick paint before she hit the far side running.
Pain shot up her left
knee. She ignored it. The suspect glanced back once. Pale face. Narrow chin.
A flash of something bone
white clenched in his fist.
Then he plunged into the
crush of late-night Soho foot traffic and vanished behind a knot of smokers outside a basement club. Quinn shoved through them. “Police.” No one moved fast enough.
A woman swore as Quinn’s
shoulder clipped her drink.
Ice and gin splashed her
coat.
Music pounded up from below
street level, bass heavy enough to shake the railings, and the alley ahead breathed out stale beer, fryer fat and wet brick.
She saw him again at
the far end, one hand on the wall as he slewed round the corner. He knew the ground. That much was plain.
He never hesitated, never wasted
a step. This was not panic. It was route memory.
Quinn touched the radio clipped
to her coat. “Control, this is DI Quinn. Foot pursuit, male, white, mid-thirties, charcoal hoodie, dark jeans. Heading north from Old Compton Street towards Soho Square. Possible connection to the Hatherley homicide. I need units ahead of me.” Static crackled. Then a clipped voice. “Received, DI Quinn. Nearest unit is six minutes out.” “Useless.”
She killed the transmission and
ran harder.
Rain had turned the pavements
treacherous
. Water sheeted along the kerb, carrying cigarette ends, wrappers, a red
silk
scarf that coiled round a drain like a vein. Neon from sex shops and noodle bars broke in every puddle, bright and ugly, green, red,
electric
blue. Each step sent dirty water up the backs of Quinn’s trousers.
Her coat clung to her
shoulders.
Her leather watch strap had
gone dark with rain. The suspect darted through a gap between two delivery vans. Quinn followed and burst into a service lane where bins lined the wall like waiting teeth. The smell hit first, rotting fruit, sour milk, bleach. Then movement to her right.
He swung a bin lid
at her head. Quinn ducked. Metal shrieked against brick.
She drove her shoulder into
his ribs. Both of them slammed into the wall hard enough to scatter water from the drainpipe above. The white object flew from his hand, bounced once near the gutter, and skated under a parked scooter.
He snarled and jabbed with
something in his sleeve, a short blade or sharpened key. Quinn caught his wrist, twisted, felt tendons slip under wet skin.
He dropped the weapon with
a hiss. It rang on the cobbles. “Done,” she said. “On your knees.” He stamped on her instep, tore free and bolted. Quinn lunged for the fallen object instead. Bone. A token, hand-carved, smooth from use, no larger than a poker chip. One side held a drilled hole darkened with soot. The other bore a tiny set of scales
etched
with unnatural precision.
She knew evidence when she
saw it. She also knew bait. By the time she rose, the suspect had reached the mouth of the lane. He looked back again. This time he smiled. Then he ran. Quinn shoved the token into her pocket and went after him.
He took Greek Street, then
cut east.
He favoured the shadows, hugging
shuttered shopfronts, slipping past stacks of black bags waiting for collection. A pair of constables appeared at the far end of the road just in time to block a cyclist and nothing else. The suspect dropped down three steps into a narrow arcade lined with locked boutiques. Quinn shouted and pointed. The constables moved late, and he slipped through the iron gate before they reached it.
By the time Quinn hit
the arcade, the gate stood half-open and groaning on its hinge. One of the constables puffed up beside her. “Ma’am, that passage dead-ends.” “Then he climbed.” They pushed through. The arcade narrowed to a covered service corridor roofed in dirty glass. Water drummed overhead. Mannequins without heads watched from dark windows. At the far end sat
not a dead end but a goods lift with its cage doors spread open
. Descending. Quinn saw the indicator crawl past B1. The constable peered at her. Young. Spots on his chin. Breathless already. “There’s no lower level on the plans.” “Tonight there is.” She sprinted for the lift. The cage had almost dropped out of reach when she caught the inner gate, fingers slipping on rust. The young constable grabbed her elbow, hauling her back before it took her hand off. The lift clanked away into darkness. “Bloody hell.” Quinn bent, hands on thighs for one sharp breath, then straightened. “Stairs.” “There aren’t any.” She
scanned
the corridor. Display windows. Loading doors. Fire alarms. A brass directory from another decade.
Then she saw it, a
fresh smear on the floor where muddy trainer soles had pivoted towards a panelled wall. Too neat. Too clean. The timber grain did not match the boards beside it. Quinn drew her sidearm. The constables copied her, both of them nervous now. “Stay behind me.” She pushed the panel. Nothing. She pressed lower, found the give, and the section swung inward on silent hinges. Cold air exhaled from below, rank with dust, damp concrete and something sweeter underneath, incense or rot dressed as incense. A stairwell dropped steeply into the earth, lit by low amber bulbs caged in wire. The older constable swallowed. “This wasn’t here when we did licensing checks.” “No one asked your permission.” She started down. Boots rang on metal treads. The sound changed after twenty steps. Wider space. Open chamber. Voices drifted up, too many to count, layered and close. Deals struck in murmurs. Laughter cut short. A child crying, no, not a child, something with a child’s pitch and a smoker’s cough. The stairwell ended at a tiled tunnel. Old Underground by the look of it. Cream tiles cracked and nicotine-stained, station roundels chiselled away, cables looped along the ceiling like black vines. New life had grown in the corpse of the place. Bare bulbs hung from hooks. Coloured lanterns glowed from side passages. Hand-painted arrows pointed deeper in, marked with symbols Quinn did not know. And at the tunnel mouth, painted in flaking red on the wall, two words. VEIL MARKET The older constable stopped dead. “Ma’am, we need backup.” Quinn glanced at him. “We needed backup fifteen minutes ago.” “This isn’t legal.” “That’s one theory.” A figure emerged from the murk pushing a tea trolley. At first glance she
looked like an elderly woman in a quilted
coat and fingerless gloves. At second glance her neck bent one joint too many as she peered at them, and her eyes reflected the lantern light silver like coins at the bottom of deep water. “Token,” she rasped. Quinn kept her gun low but ready. “Police. We’re in pursuit of a suspect.” “Token.” The tea seller smiled. Her gums were black. Tiny cups rattled on the trolley with each tremor of the wheels. The younger constable whispered, “Jesus.” “Not his station,” the woman said. People had begun to notice them. Faces appeared in the adjoining passages, then withdrew. A thin man in a butcher’s apron. Two girls with shaved heads and matching fox-fur collars. A child holding a cage covered with cloth, the thing beneath it scratching in impatient bursts. Farther in, under the old station vault, rows of stalls bloomed out of the dark. Tarpaulin awnings, glass cases, trestle tables lit by candle jars and battery lamps. Jars of powders. Bundles of dried herbs. Jewellery made from teeth and brass. Old books chained shut. Bottles filled with liquid that moved against gravity. The suspect cut through the crowd fifty yards ahead. Charcoal hoodie. Quick shoulders. He glanced back once and vanished behind a stall draped in red
silk
strips. Quinn pulled the bone token from her pocket. The tea seller’s smile widened. “Entry for one.” “I’m not asking.” “Still one.” The older constable set a hand near Quinn’s sleeve but did not touch. “Ma’am, if we go in blind and this turns ugly, no one up there even knows where we are.” Quinn looked at the token, then at the market beyond. The tunnel amplified every sound until each footstep and mutter
seemed to
come from several directions at once. No maps. No warrant worth the paper. No support. DS Morris had walked into an empty riverside warehouse three years ago because he had trusted the shape of ordinary crime. Quinn had found only blood, burnt metal and footprints that ended at a locked wall. Internal review had called it gang-related. Quinn had read the scene report until the lies showed through the ink. This felt like the same seam opening under her feet. The younger constable said, too loud, “We can lock down the exits.” “Can you see the exits?” He fell silent. A man brushed past Quinn on his way out. He wore a
velvet
dinner jacket over hospital scrubs. His hand
was wrapped
in bloody bandages. He dropped a coin into the tea seller’s saucer without breaking stride. The coin hissed on contact, as if hot. From somewhere inside the market came a burst of shouting. Then a gunshot. The whole tunnel snapped taut. Traders ducked. Lanterns swung. The tea trolley rattled as the old woman seized it with both hands and hissed through her teeth. Quinn moved before thought could slow her. She slapped the token into the tea seller’s palm and strode into the market. “Stay at the entrance,” she told the constables. “Anyone comes out in a charcoal hoodie, you put him on the floor.” “Ma’am, that order is insane.” “Good. Follow it.” The market swallowed her at once. The old platform had become a bazaar of the obscene and the practical. A fishmonger hacked at something with too many ribs. A woman in a cream wedding dress sold lockets from a pram lined with black
velvet
. At one stall, a square-jawed man with tattooed eyelids weighed teeth on brass scales, then shook his head at an angry customer clutching a
velvet
purse. The air carried cardamom, lamp oil, blood, wet wool and the
electric
tang before lightning, though no sky sat above them. Quinn kept her gun close to her thigh and her eyes moving. “Police. Out of the way.” That won her stares and little else. Ahead, panic rippled through the crowd. People shoved back from a knot of bodies near an old station map case. Quinn shouldered through and saw the first casualty, a bald trader on his knees clutching his side, blood spilling between his fingers. Not arterial. Lucky. Beside him, a
shattered
glass cabinet leaked blue liquid across the platform. It smoked where it touched the tiles. A man in a long green coat pointed with a trembling hand. “He stole from Marrow Finch and shot Rafi.” “Which way?” The man stared at her badge, then at the gun, then at her face
as if arranging her into some private category
. “North tunnel. Goods line.” Quinn turned and caught motion at the edge of sight. Charcoal hoodie, vanishing through a maintenance gate marked STAFF ONLY in peeling letters. She ran. The crowd thinned beyond the stalls. The station gave way to raw service passages where brick sweated behind the flaked tile and pipes clanged overhead. Her breath rasped in the enclosed dark. The suspect’s
footsteps
slapped ahead, sometimes near, sometimes far, thrown by the curves of the tunnel. He knew the acoustics. Clever bastard. “Armed suspect,” Quinn shouted into her radio as she ran. “Underground
structure
beneath Camden, unregistered access route from Soho arcade. I’m in pursuit. Send firearms, BTP, everyone.” Static. Then fragments. “...repeat location... signal weak...” “Of course it is.” The tunnel forked. On the wall, someone had painted symbols in white chalk. One arrow showed a circle pierced by three lines. Another showed a hand with six fingers. A third had
been smeared
by a wet shoulder. Quinn crouched. Fresh mud marked the left branch. Blood, too, just a thumbprint on brick at shoulder height. His, perhaps. Or someone else’s. She took the left. The passage opened on an abandoned platform where old adverts peeled from the walls in long damp curls. A train sat on the track below, carriages blacked out, doors hanging open. Not an Underground train. Too narrow. Too old. Its windows had
been painted
from the inside. Cables snaked from its roof into generator units on the far platform. Footsteps hammered on metal. Quinn looked up. The suspect sprinted across the roof of the first carriage. “Stop or I’ll shoot!” He turned as he ran and fired instead. The shot cracked the tile pillar by Quinn’s head. Shards stung her cheek. She fired once in return, not to kill, to break his stride. The bullet rang off the carriage roof near his feet. He stumbled, windmilled, recovered. Fast.
Then another figure rose from
inside the open train door and grabbed his ankle. The suspect screamed and kicked. Quinn saw only pale hands at first, then a face lifting from the dark, gaunt, olive-skinned, short curly hair plastered to his brow with sweat. A Saint Christopher medallion flashed at his throat. Tomás Herrera. “Gun,” he barked. “Mind the gun.” The suspect wrenched free, but the weapon flew from his hand and clattered down between the carriage and the platform edge. Quinn holstered, jumped to the track bed, snatched the pistol, and hauled herself up the opposite side. Herrera dropped from the carriage roof with less care than sense and hit hard, one hand pressed to his left forearm where a dark stain spread over his sleeve. “You’re bleeding.” “Add it to my file.” “Police,” Quinn said. “I gathered.” The suspect had reached the end of the platform. A steel gate blocked the tunnel beyond. He slammed into it, clawed at a chain wound through the bars, then spun as he realised he had trapped himself. He had the bone-white face Quinn had glimpsed in the alley,
not pale by birth but drained by fright
. Rain still shone on his hood. His chest sawed. In his right hand he held
not a second gun but a glass vial stoppered with wax, the contents black
and shifting, as if it held smoke under water. Herrera went still. “Oh, that is bad.” Quinn levelled the recovered pistol. “Put it down.” The suspect’s laugh came out ragged. “You don’t know what this place does to coppers.” “Interesting sales pitch. Put it down.” He glanced at Herrera. “You sold me out.” Herrera spat blood at the track. “You shot Rafi, idiot.” “Rafi skimmed.” “Everyone skims. You don’t shoot over percentages.” The suspect’s thumb dug under the wax seal. Quinn moved left for a cleaner angle. Herrera moved right, favouring his injured arm. Between them, the suspect’s eyes darted, wild and bright. “What’s in the vial?” Quinn asked. “No clue,” Herrera said. “That’s the honest answer. Finch keeps surprises.” “Helpful.” “Welcome to the Market.” The suspect bared his teeth. “No one takes me upstairs.” He bit the wax, tore the stopper free and hurled the vial at the rails. Glass burst. Black vapour exploded upward with a sound like a hundred people inhaling at once. The dead train shuddered. Painted windows bulged from within. Beneath Quinn’s boots, something in the dark undercarriage woke and
started to
pound against the metal.
Then the chained gate behind
the suspect
began to
open on its own.
