You are an expert and award-winning novel writer in the dark Mystery 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 mystery genre. A detective arrives at a crime scene in an unusual location. Something is wrong — the evidence doesn't add up. A colleague is present, offering a different interpretation. Through careful observation and deduction, the detective begins to see what others have missed. 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>

A brass needle spun violently
as Harlow Quinn slid the Veil Compass across broken platform tiles.
She flinched when the needle
jerked toward the yawning tunnel mouth, metal teeth chattering.
She kept her gaze locked
on its restless
dance
while Eva Kowalski crouched by the body, fingers brushing a patterned stain across the man’s collar. “Unnatural,”
Eva murmured, tucking a fiery
curl behind her left ear. “Blood shouldn’t pool like that and stay so dark.” Harlow dropped to one knee, boot scuffing the grimy grout. Sharp
jaw clenched
, she
traced
the stain’s slick edges. Copper stung her nostrils. Recent. Too recent. “It’s not just the pattern,”
she said, voice low
. “Look at the contact points. No spray. No spatter. He lay there willingly.” Eva adjusted her round glasses, green eyes bright behind worn lenses.
She pulled a slender notebook
from her satchel, pages filled with archaic symbols. “Ritual binding requires precise placement. That stain maps a symbol of devotion.”
Her tone held excitement, as
though she’d found a piece in a jigsaw puzzle. Quinn rose, boots
echoing
.
She surveyed the silent stalls
lining the half-collapsed arches.
Each one bristled with forbidden
goods—ivory-coloured bone charms, jars of liquid moonlight, coils of hair labelled by date. No witness, no witness at all. Yet the place hummed with something unseen. Eva caught her eye. “Someone planned this. Someone with access to both occult tomes and—” “—and police credentials,”
Harlow finished sharply
.
She stepped to the nearest
stall, hands hovering above a cluster of antler-tipped wands. Faded footprints arced around the corpse, heading back toward the tunnel. Unmistakable: heavy-soled boots, but no drag marks where the body should have
been carried
. “You spotted that,” Eva said. “I thought he collapsed on the spot.” Quinn tilted her head. “Not a bruise on his ankles. No abrasion on his palms. Whoever killed him moved him here after.”
She flicked her worn leather
watch
on her left wrist, its face scratched but still precise. “So why stage the scene in a half-abandoned Tube station no one’s used since the Eighties?”
Eva flipped back to her
notebook. “Access requires a bone token. Whoever left this body wanted him to be caught here. Public enough for us to find him, private enough for the ritual to work.” “Hm.”
Harlow crouched again, dropping a
gloved finger into a shallow depression in the tile. “Look at this. A depressurised crack. Something forced itself through.”
She scraped at the edge
. “This station never saw traffic. Maintenance closed it decades ago. That fissure didn’t widen on its own.”
She pulled a small torch
from her pocket, beam narrow and bright.
She swept it across the
tunnel walls. Ancient adverts peeled off plaster, slogans praising long-forgotten bakeries. Under her light the fissure glimmered with something oily, iridescent. Eva crouched beside her, breath quick. “Spectral residue,” Eva whispered. Quinn stood, shoulders squared. “Place this in context. Someone staged a body, scattered ritual implements, then opened a portal.”
She flipped the compass in
her hand. The needle
quivered
, now pointing directly down the tunnel. “And our victim? He volunteered, or they lured him.” Eva closed her notebook. “No ID on him.” “We’ll find it,”
Harlow said, voice crisp
. “He won’t stay nameless long.”
She swept her gaze back
to the stalls. Rusted chains dangled from an iron beam overhead. A hollow clang answered her touch. “Someone left in a hurry.” Eva rose, satchel clinking.
She brushed dust from a
carved ivory token lying near the corpse’s hand. A bone token, small and polished,
etched
with a looping rune. “He carried this in his pocket. Entry requirement.” Harlow snatched a latex glove and slipped it on, fingertips grazing the token. She flipped it over. “Entry and exit,” she said. “He needed it to leave. Whoever called him back in must have taken theirs.” A sudden hum cracked the
silence
. The torch
flickered
, then steadied. Eva’s
eyes widened
. “Infrasound,” Harlow said.
She slammed the torch to
full power. The fissure
pulsed
, a shallow breath in the earth. The compass needle whipped back and forth, desperate. Eva swallowed. “That’s new energy. Building fast.” Quinn patted her pocket, found a small mirror.
She angled the beam at
the crack. The reflective face of the mirror captured something beyond the fissure: a shimmer, rippling like a heat haze. Something
tried to
push through. She straightened. “You said ritual binding demands an anchor, yes?” Eva nodded, hair flicking, freckles paling. “The victim’s devotion bound him. But no one crosses over until the anchor is complete.” “So this body was never meant to be his anchor.” Quinn turned to the tunnel, voice flat. “It’s a decoy.” A gust of air blasted the platform. Bits of plaster rained down. The shimmering blurred, then brightened. From the fracture, a shape burst forth—tall, slender,
utterly
dark. It collapsed on its knees, arms sweeping out to drink the station’s stale air. Harlow yanked her service pistol free. She tightened her grip. “Step back,”
she ordered Eva, voice steady
like a drill sergeant. “Stay behind me.” Eva pressed herself against the far wall, hand on the bone token in her satchel. She whispered under her breath, something in Polish. The figure lifted its head. No features. A void where a face might have been. It drew in another breath and rose, limbs stretching. Every step made the crack widen further, the station trembling. Harlow edged forward, pistol levelled. “Identify yourself,” she commanded. “Now.” The shadow lifted an arm. A finger pointed at the stalls. Then at the body. Then back at Harlow. It spoke in a voice like distant thunder, syllables that twisted the air. Harlow pressed her tongue to the roof of her mouth, resisted the urge to flinch. She glanced at Eva, whose round glasses caught the torchlight. Eva swallowed. “It recognises you,”
Eva said, voice tight
. Quinn’s brown
eyes narrowed
. “Of course it does.” The shadow moved faster than light, darting behind a stall of silver-filigreed vials. Harlow fired. The shot
shattered
glass. Liquid flame licked up the iron girders. Heat scorched her cheek. Eva leaped toward the bone token she’d pulled from her satchel. She dropped to her knees,
tracing
a sigil in the dust with trembling finger. Quinn pivoted,
scanning
. Chains above rattled. Sparks fell. The shadow hovered there, knuckles white against rusted links. Then it dropped. It lunged for Harlow, voice crackling like static. Harlow squeezed the trigger again. No effect. The bullet disintegrated on impact, leaving a white scorch. The creature stumbled but regained shape instantly. Eva’s chant grew louder. Her voice cracked, but each word held power. The shadow recoiled, head whipping toward her. The fissure behind them
pulsed
, dark mouth widening. Harlow dashed to her, yanked Eva up. “Not here,” she barked. She grabbed the bone token from Eva’s hand and held it high. The compass on her other hand spun, the needle pointing at the token like a lodestone. Eva crouched, voice trembling. “We need to anchor it back—before it grows too strong.” Harlow glanced at the fissure. It spurted tendrils of dark smoke, curling out to snatch at their ankles. She raised the token, palm clammy. “One wrong move—” A footstep
echoed
behind them. Someone else entered the platform, silhouetted in torchlight. Another figure. A living, breathing human. Harlow’s jaw tightened. The newcomer raised empty hands. “Detective Quinn?” Harlow didn’t lower the token. The shadow shrieked, twisting into a razor-edged spiral. Eva slammed her palm down on the token’s face, sealing the rune. The fissure snapped shut in an instant. Darkness collapsed, dragging the shadow with it. Silence
echoed
. The only sound was the crackle of the burning stall and Harlow’s steady breathing. She backed away, token still raised, pistol aimed at the newcomer. Her bearings snapped back into focus. “That was too close,”
the newcomer said, voice precise
. “I’m DS Darrow. We’ve got reinforcements on the station above. “We?”
Harlow asked, eyes hard
. Darrow nodded, torchbeam revealing a face drained pale. “Orders came through boss. Get you out.” Eva sank to her heels, breath ragged. She wiped dirt from her glasses. “No time. We lost the body. The token’s ours. The portal closed.” “Hate to break it to you,” Harlow said, voice low, “but that body wasn’t the anchor. Something else slipped through.” Darrow swallowed. “What do you mean?” Harlow
flicked
her
watch
to life. Its face caught the dying embers. “The victim was a red herring. The real target is still out there, crossing stations by moonlight. We just saw it.” She planted the bone token on the platform, as though in salute. “This market moves. We need to follow.” Darrow’s jaw twitched. Reinforcement boots clattered down the corridor, voices shouting. Harlow
flicked
the Veil Compass into her jacket pocket, patina
gleaming
. She turned back to the tunnel mouth, where
echoes
of something distant whispered in the darkness. She glanced at Eva, green eyes bright with fear and
resolve
. Then she fixed Darrow with a glare. “Move. We chase before it finds its next victim.” The station
trembled
again. A distant roar,
not quite human, bounced off the walls
. Harlow took the first step into the tunnel. Everything she knew about crime scenes told her to wait for backup. But this was no ordinary crime. She stalked forward, Eva at her heels, Darrow frozen a moment longer.
By the time the officers
from above reached the platform, the three of them had vanished into the black. And somewhere in the labyrinth beneath Camden, the Veil Market had just reopened for business.
