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>

She ducked under the sagging
caution tape, the yellow plastic a
stark
, ludicrous line against the grimy concrete of the abandoned Tube platform.
The air hung thick with
the metallic tang of dried blood and the damp, earthy smell of deep London soil. Below, the tracks yawned, a black
maw
swallowed by deeper shadow. "Took your time, Detective,"
DS Miller’s voice cut through
the hum of generator lights.
He stood over a huddle
of forensics techs, hands jammed into his pockets, a fresh uniform looking a little too
pristine
for the scene.
Quinn shifted her weight, the
worn leather
watch
on
her
left wrist catching a
glint
of the portable lighting rigs.
Her closely cropped salt-and-pepper hair
did little to ward off the
chill
seeping from the station walls. "Priority call at Liverpool Street. What have we got?"
Miller gestured vaguely towards the
victim. "Male, early thirties. Found by a homeless bloke looking for shelter. Stab wounds. Looks like a turf war, maybe a drug deal gone south. Standard stuff for this part of town."
She moved past him, her
eyes
scanning
the scene with military precision. The platform felt too quiet, too still, even for a murder.
The victim lay splayed near
the edge of the derelict platform, his skin pallid under the harsh lights.
His clothes, though stained and
torn, seemed… specific.
A dark wool coat, not
the typical cheap puffer of a street dealer. Frayed, yes, but good quality at one point. "Standard stuff?"
Quinn knelt, ignoring the tech’s
grunt of annoyance.
She pulled on a new
pair of latex gloves. The man’s eyes were open, fixed on the grimy concrete ceiling
as if staring at a forgotten god
.
His lips were parted, a
silent gasp frozen in death. "Multiple lacerations to the chest and abdomen,"
a forensic officer muttered, snapping
photos. "No defensive wounds on the hands, interestingly. Minimal struggle apparent, beyond the initial altercation." Quinn saw it immediately.
The bloodstains on the wall
behind the victim spread in an unnatural pattern, almost too neat, lacking the wild spatter of a desperate fight.
A faint, cloying scent, like
burnt sugar mixed with something acrid, clung to the air beneath the metallic tang of blood. She took a deep breath, trying to place it. Not chemicals, not
standard
forensics. Something other. "No defensive wounds, but he’s been gutted like a fish,"
Quinn observed, her gaze sharp
. "And this is a Tube station, Miller. Not an alleyway." Miller crouched beside
her
, his expression a careful mask of deference and slight impatience. "Plenty of tunnels in London. Could have been dragged here, then dumped."
He pointed to a drag
mark leading deeper into the disused tunnel. "We're checking down there now." "Dragged?" Quinn leaned closer to the body. His left hand
was curled
, still gripping something small and white.
She carefully pried his fingers
open. A chip of bone. Old, smooth, the kind of relic one might find in an antique shop, except for the faint, almost invisible
etching
on its surface – a symbol.
It reminded her of something
she’d seen once, years ago, in a dusty archive Morris had dragged
her
to. "What's that, then?" Miller asked, leaning in. "Looks like a bone." Quinn straightened, holding the chip delicately in the gloved palm of
her
hand. "But not just any bone." Memories stirred, unsettling and unwelcome. She pushed them down. "Souvenir from a date night, perhaps?" Miller offered with a weak chuckle. "Or a voodoo thing. We get weirder every week." Quinn ignored him.
She glanced at the victim’s
neck. A thin, silver chain lay broken, half-buried in the grime. No pendant. She looked around. The floor was rough, uneven, decades of grit and discarded rubbish making it a
mosaic
of urban decay. Nothing caught
her
eye. "Find anything else on him?"
she asked the forensic tech
. "Wallet, phone, no ID as yet. Cash. Expensive
watch
, though." The tech pointed to the man's right wrist. A sleek, modern timepiece, a silver bezel, a
stark
contrast to Quinn’s own worn leather
watch
. "What about entry points to this station?" Quinn rose, pacing the length of the platform. "Secure?" Miller gestured towards an officer by a ventilation shaft. "Entrance through an old maintenance shaft a few blocks north. Mostly sealed, few loose bricks. How the homeless guy got in." "And out?" "Same way." Quinn paused.
Her brown eyes narrowed, taking
in the scene again. The sparse scattering of debris, the faint graffiti on the walls. Nothing out of place, nothing screaming a struggle beyond the body itself. The air, though, still carried that faint, sickly sweet odour. "Any signs of forced entry on the victim himself? Beyond the obvious." "No blunt force trauma we can see, barring the stab wounds. Looks fairly direct." "Direct." Quinn repeated the word, tasting it. Too direct, perhaps.
She walked to the edge
of the platform, looked down into the inky blackness between the tracks. The air grew thicker down there, colder. A faint, almost imperceptible hum
reverberated
through the soles of
her
boots. It was a
familiar
sensation, a tremor that used to make the hairs on
her
arms stand on end.
She hadn't felt it since
the Morris case. "Miller," she called out, turning. "Bag that bone fragment
carefully
. And I want a full sweep of this entire platform. Every crevice. Every dust bunny. And a chemical analysis of the blood, beyond just DNA. I want to know if there's anything else in there." "Detective, we’ve already got a uniform doing a sweep." Miller looked irritated, his professional mask slipping. "And the chem analysis is
standard
procedure, but this isn't exactly a lab. We'll get it to the pathology lab, but it'll take time." "Then we’ll wait." Quinn’s voice held a steely edge that brooked no argument. "I want to know what that smell is. And why a man who takes a brutal gutting without a fight is found clutching a fragment of bone." She walked towards the entrance of the disused tunnel, beckoning a uniform to light the way. The hum grew stronger, vibrating in
her
teeth. It wasn't the rumble of a distant Underground train. It was something else. She knew it was. The tunnel stretched endlessly, a dark
maw
. "Careful, Detective," Miller warned from behind
her
. "Gas." Quinn ignored him, pushing deeper. The faint, sweet smell grew stronger here, mingling with the metallic stench of the underground. She ran a gloved hand along the rough brick wall. Cold, damp.
Further in, a faint etching
presented itself, barely visible under a layer of grime. A
familiar
symbol. The same one on the bone fragment. Her breath hitched. Morris. His case had
been closed
, ruled an accident. But she had seen things then. Things she couldn’t explain. The way the air had felt, the way the shadows had moved. This, now, felt unsettlingly similar. A
chill
that went deeper than the underground air. "What is it?" Miller’s flashlight beam cut through the darkness, illuminating the symbol. "Nothing." Quinn pulled
her
hand back,
her
face
unreadable
. "Just old graffiti." She stood there for a moment,
her
mind
racing
, searching for a logical explanation. A cult? A gang with a bizarre initiation rite? But the symbol felt ancient, wrong for any street gang. She turned, walking back towards the platform,
her
eyes
scanning
the ceiling as she went. The victim’s eyes, fixed on the concrete. What had he seen? What had a man who'd died without putting up a fight been looking at in his final moments? Back on the platform, she returned to the body. The forensic tech had finished initial photographs and
was preparing
to move the body. Quinn held up a hand. "Hold on." She
scanned
the area around the victim once more. Her gaze fell on a small, dark stain near the man's head, partially obscured by the collar of his coat. It was small, almost insignificant, a dark smudge against the lighter dried blood. Not blood, though. It was oily, almost iridescent under the harsh lights. She knelt again,
carefully
scraping a tiny sample into a sterile vial. The burnt sugar scent intensified
slightly
. "What's that, now?" Miller asked, stepping closer. "An anomaly." Quinn secured the vial. She looked at the blood spatter on the wall again. The unnatural spread. No struggle. The broken chain, the missing pendant. The weird bone fragment. The faint, sickly sweet smell. And the symbol,
etched
in the tunnel. Her jaw, usually sharp, tightened. This wasn't a mugging. This wasn't a drug deal. It was a ritual. A messy, brutal, but ultimately *
deliberate
* ritual. The thought
sent a shiver down
her
spine. The kind of messy ritual that had ended
her
partner. "Miller,"
she said, without turning, her voice low
. "I need every CCTV camera feed for three blocks around that ventilation shaft. I want to know who entered this station in the last forty-eight hours, and who left." "We've already got uniforms canvassing, Detective. Standard procedure." "This isn't
standard
, Miller."
Quinn stood, her eyes locking onto his
. "This is a cold kill. A setup. He was killed here, right here, and no one tried to stop it. They *
wanted
* him found." "Why?" Miller frowned, genuinely puzzled now. "That's what we're going to find out." She looked from the body, to the bone fragment in the forensics bag, to the dark mouth of the tunnel where the symbol lay hidden. The hum still
resonated
in the air, a low thrumming under the city’s roar. "Did anyone else report that smell?" Quinn asked the nearest forensic tech, who was now bagging the victim's personal effects. The tech sniffed the air, confused. "Smell? Just blood, ma'am. And the usual Tube damp." Quinn straightened, a singular thought crystallising in
her
mind. No one else noticed the smell. No one else
seemed to
hear the hum. Just like with Morris. She
wasn’t losing
her
mind. She
was seeing
what others couldn’t. Or wouldn’t. The missing pendant. It meant something. It belonged to the chain on the victim's neck. But if it was broken, and missing, who had it? She turned
her
sharp jaw towards Miller. "Find me the homeless man who reported this." Miller puffed out his chest a little. "Already sent a car to pick him up from the shelter. He’s being brought in for questioning." "Good." Quinn walked along the platform one last time, away from the body, towards the flickering entrance lights. She kept
her
eyes on the ground, searching,
her
boots scuffing gritty concrete.
Then she spotted it, almost
missed in the uneven light. A tiny, almost translucent sliver of something
crystalline
, no bigger than a fingernail clipping, shimmering faintly near a discarded fast-food wrapper. It wasn't glass. It felt cold, unnaturally so, even in the
chill
of the station. She bent, scooped it up, careful not to damage it. It felt like ice, despite the ambient temperature. It
pulsed
with a faint, internal light, almost too dim to perceive. A shard of something, something that shouldn't exist. "What are you doing, Detective?" Miller asked, already moving towards the platform exit. Quinn ignored him. She held the shard up. It
pulsed
again, a soft, unnatural
throb
in
her
gloved hand. Her
eyes narrowed
. This wasn't just a murder. This was a doorway. She heard a faint click behind
her
, then the sudden rush of air as the forensic team finally hauled the victim’s body onto the stretcher. His head lolled unnervingly, his open eyes still fixed on the concrete ceiling. But now, it almost seemed as if they
were looking
directly at *
her
*. A shudder ran through Quinn. She didn't believe in ghosts, not
really
, but what she experienced with Morris left
her
with a healthy dose of unease when faced with the inexplicable. That hum, that scent, those symbols. Someone
was pulling
strings here. Strings made of something far older and darker than drugs or gang turf. "Miller!" she barked, turning to face him just as he was about to step past the tape. "That homeless man. I want him brought directly to my office. And I want a full breakdown of any similar incidents in abandoned locations. Over the last five years. Any unexplained deaths, any unusual missing persons." Miller stopped, his brows
furrowed
. "Detective, that's going to be a massive traw-" "Find it." Her voice was flat, unyielding. She looked down at the shimmering shard in
her
hand. It felt like a piece of a puzzle, a fragment of something
otherworldly
. And she had a horrible feeling it pointed to the same dark path that had consumed DS Morris. The victim's eyes, even from the gurney,
felt like they were watching her
. And then, as the stretcher wheeled away, she saw it. Tucked almost imperceptibly into the victim's inner lapel, a small metal plate with an address
