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>

Quinn caught the falling bone
token before it vanished beneath the platform edge.
It lay cold against her
palm, carved from a child’s finger bone and drilled through with a neat black hole.
Her gloved thumb brushed a
red smear from its edge. Blood, fresh enough to shine. “Tell me this is evidence, not an entrance fee.”
DS Niall Mercer stood beside
a shuttered ticket office, his blue scene suit crackling at the elbows.
He stared at the token
as if it had grown teeth. “Uniform found it in the deceased’s pocket.” “Then bag it.”
Mercer held out an evidence
pouch. Quinn dropped the token inside, watched him seal it, then pushed through the crooked metal gate that blocked the old Tube platform.
The station had lost its
name decades ago.
Someone had chipped the enamel
signs down to blank blue slabs, but the old Underground roundels still showed through the grime like bruises beneath skin.
Electricity ran where no current
ought to exist.
Strings of mismatched lamps hung
from rusted girders, their glass shades painted in lurid colours. Green light soaked one end of the platform.
A strip of violet glimmered
over the tracks.
The Veil Market had packed
itself away in a hurry.
Stalls stood empty beneath patched
awnings.
A butcher’s hook swung above
a counter scattered with teeth, most human, some not. Tarnished bottles crowded another stall, each stopper sealed in wax and marked with warning sigils.
Quinn caught the sharp smells
of anise, burned hair, damp brick and old coins. At the far end, someone had chalked a white line around a body.
Mercer fell into step beside
her. “Local rumour says it’s a fringe occult bazaar. Costumes, street magic, that sort of thing.”
Quinn glanced at a glass
jar containing three pale eyes floating in yellow fluid. “Do street magicians usually sell organs by the jar?” “Could be animal parts.” “Get one tested.”
The body lay between the
rails, arranged with care on the black gravel. Male. Mid-thirties. Narrow face, dark hair shaved at the sides, expensive charcoal coat.
His arms crossed over his
chest, hands tucked beneath opposite elbows. Someone had placed two old pennies over his eyes. Quinn crouched at the platform edge. The track bed lay nearly two metres below. No ladder. No steps. The dust on the far rail remained smooth except for the boot marks around the corpse, and each mark pointed away from it. Mercer held a torch over the dead man’s face. “Victim is Adrian Vale. Forty-three. Owner of Vale Restorations in Clerkenwell. Antiques, private collections, discreet clients. His driving licence had an address in Hampstead.” “Cause?” “Pathologist wants the post-mortem. He’s got a wound under the coat. One stab, from the look of it.” “Blood?” “Not much.” Quinn studied the ballast. A dark pool had formed beneath the man’s left shoulder, but it barely filled a dinner plate.
His coat had soaked through
at the back. Blood had dried in the seams, thick and almost black. “He didn’t die here.” Mercer looked down. “He could have bled internally.” “Then why arrange him? Why put coins on his eyes? Why bring him into a station that has no public entrance?” “People do strange things around a body. Guilt, panic, ritual. The market lot might have found him and played at funeral rites.” Quinn climbed down from the platform, boots finding purchase on the rail sleepers. The old steel hummed under her soles. No train ran through this tunnel. Still, the sound travelled along the metal in a low, patient
pulse
. Mercer followed, less gracefully. “You’ve got a theory?” “I’ve got a dead man who was carried in by at least two people.”
She pointed to the gravel
near Vale’s polished shoes. Deep heel impressions dented the ballast. One set belonged to a large boot with a chevron tread. The other showed a narrow sole, smooth at the front, with a chipped heel. “Neither print matches the victim. He wore handmade brogues. Look at the toes, no drag marks. His carriers lowered him, then lifted him again.” “Lifted him?” “They put him down first. Blood transferred to the stones in a broad patch beneath his back. Then they moved him six inches to the right. See the clean crescent? His body blocked the first spill.” Mercer crouched, his expression hardening. “Why?” “Because they wanted him
precisely
here.” Quinn followed the rails with her eyes. The corpse rested where two tracks converged beneath a broken signal box. Above it, a faded station map clung to tiled wall. Thin red lines marked routes that London had buried long ago. Yet one route had changed. A fresh line, black as ink, cut across the old map.
It started at the station
symbol beneath Quinn’s feet and ran north-west through a patch of empty wall. At its end, someone had drawn a small door. Mercer shone his torch upward. “That wasn’t there when forensics came through.” “Photograph it.” A sharp click answered from the platform. “Already did.” Eva Kowalski stood beside the chalk line, her worn leather satchel pressed tight to her hip.
Her curly red hair had
escaped its clip and framed a face gone pale beneath its freckles. Round glasses flashed green in the hanging lights. Quinn rose. “This scene is restricted.” Eva tucked a loose curl behind her left ear. “I work in the British Museum archives. Restriction is most of my day.” “You’re not museum staff tonight.” “No. Tonight, I’m someone who knows what that mark means.” Mercer looked between them. “Do you know her?” “I know her name.” Quinn kept her attention on Eva. “And I know you’ve breached a police cordon.” Eva’s green eyes moved to the body. Her mouth tightened. “Mr Vale came to the archive last week. He requested access to a group of sealed Assyrian tablets. The curator refused him. He had copied the catalogue references before security removed him.” “What tablets?” “The Namtar fragments. They describe threshold rites, doorways between places. Most scholars call them temple myths.” “Most?” Mercer asked. Eva looked at the jars, the teeth, the stalls draped in old
velvet
. “Most scholars do not visit the places where myths shop.” Quinn climbed back onto the platform.
She stopped an arm’s length
from Eva. “Why did Vale want them?” “He brought a brass compass. Small, old, covered in protective marks. He asked where it pointed.” “The Compass is missing?” Eva’s fingers closed around the strap of her satchel. “He called it a Veil Compass. A Shade artisan made it, according to the papers he showed me. The needle finds rifts, openings, things that should stay shut.” Mercer scoffed. “So our antiques dealer came down here chasing a fairy tale, got himself stabbed by a black-market trader, and his toy compass went missing. That’s a workable motive.” Quinn looked down at Vale’s arranged hands. “Then explain the coins.” “Payment for the ferryman. Ancient custom.” Mercer nodded towards the corpse. “He dealt in antiques. He liked the theatre of it.” “The coins are Edwardian,” Quinn said. “Both dates are 1908. They’ve been cleaned with citric acid. Vale’s pockets held a twenty-pound note, two bank cards and car keys. A killer who stages an ancient rite does not use coins struck two thousand years late.” Eva spoke with care. “Some rites favour the symbolism over historical accuracy.” “Do they favour bleach?” The blood on the bone token had sat bright and wet. The blood beneath Vale had crusted in layers. Quinn walked to the place where the white line ended at a narrow maintenance door. A fresh padlock hung from its hasp.
Its brass surface bore no
scratches. Dust lay undisturbed along the threshold. “Who secured this?” “A transit contractor,” Mercer said. “We cut the chain at the street level. This door was locked when we arrived.” Quinn studied the door. The lock’s keyway faced out. A thin line of pale powder ran across the jamb. Not dust. Ground bone, mixed with salt.
She looked back to the
bagged token in Mercer’s hand. “Give me that.” He passed it over. Quinn held the pouch beside the powder. The token’s drilled hole matched the width of the keyway. Fine grains of salt clung to its red-stained edge. “This wasn’t in Vale’s pocket.” Mercer blinked. “The constable said it was.” “The constable found it there. Someone planted it after death.” Eva’s face emptied. “Bone tokens are not keys.” “Then what are they?” “Admission. You show one at the Market’s entrance. The ward recognises it, and the entrance shows itself.” Quinn looked from the token to the sealed door. “This door is the entrance.” “It cannot be,” Eva said. “The Market moves with the full moon. Its doors do not stay in the same place.” “Yet here it is.” A dull impact struck the other side of the maintenance door. Mercer reached for his radio. “Control, this is DS Mercer. We need another unit at the lower access, now.” Static crackled, then shaped itself into a man’s breath. “Quinn.” Her spine locked. The voice came from the radio speaker, hoarse and close. Three years had stripped none of its shape from her memory. DS Morris. Mercer stared at the handset. “Who the hell was that?” The padlock clicked open. It dropped onto the tiles.
