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>

Harlow Quinn dropped onto the tracks before the uniform finished his sentence. Gravel slid under her boots as she ducked under the blackened lip of the platform, the stale tang of old oil clinging to the air. The dead Tube line stretched ahead in a tired grey curve, tunnel lights humming with sickly yellow halos. Twenty yards down, a ring of torch beams pinned the body like a stage spotlight. She walked, not rushed, heels kicking grit. Eighteen years on scenes like this had burned the panic out of her stride. A young constable shuffled along the platform above, helmet tucked under his arm. "Detective Quinn, Health and Safety will have my arse if a train comes through." "No trains," she said. "That is the point of an abandoned line." He shut up. The body lay just past the halfway mark between platforms, on the track bed where the sleepers sank into grimy ballast. Male, mid-twenties, wiry. Shirtless. Something had carved a jagged pattern across his chest, a mess of shallow cuts that met in the centre over his sternum. DS Rafi Singh crouched beside him, suit jacket open, tie askew. He glanced up as she approached, eyes tired but mouth already curving into his usual half grin. "Morning, boss. Thought you had the day off." "So did I." Harlow dropped to a knee opposite him, the gravel biting through her trousers. "What have we got." "Urban explorer who picked the wrong playground. Name's Tyler Nokes, according to the wallet." Rafi lifted a clear bag with a worn leather billfold inside. "Mate says they came down here to film content, you know, spooky abandoned Tube, all that. Bloke lagged behind near the entrance, next thing he is a corpse with fancy knife-work and his shoes nicked." Harlow looked at the cuts. Not deep enough for arterial spray, more like scratches that had bled but not bled out. "Time." "Pathologist estimates four, five hours. We pulled them out of the old service tunnel just after six. Mate's upstairs having a chat." She shifted her weight and traced the edge of a dark patch with a gloved finger. Blood, half-dried, sat in a tidy pool under the man's shoulders. None sprayed on the wall behind him, none on the gravel further out. "Uniforms moved him." Rafi shook his head. "Found him like that. They were spooked enough to leave him alone." Harlow frowned. "Then explain why his back is dry and all the blood sits under him." "Gravity." Rafi shrugged. "You get stabbed, you bleed out." "He was not stabbed." She pointed to the chest. "You do not bleed out from scratches like these, not unless you have an underlying condition and a lot of time. No defensive wounds on the hands either. Check the fingers, clean nails, no skin under them." "Could be he froze, went into shock." Rafi rocked back on his heels. "Kids panic, he trips on the tracks, cracks his head, they stage the scene to look like, I do not know, a ritual. Viral clout. Then they bottle it and call us when he stops breathing." She lifted Tyler Nokes's right arm, eyeing the mottled purple of lividity along the inner forearm. "It is settled along his side and back. Pathologist is off. He lay somewhere else before someone rolled him onto this bed of gravel." Rafi's grin faltered. "Boss, we are thirty feet underground. Where else is there to move him from. It is tunnels and locked doors." "You looked at all of them." "Mostly. Platform level, service corridor, storage rooms. You know the drill, quick sweep while SOCO set up. This whole place is a bloody maze. They bricked half of it up after the war." Her gaze drifted past him, down the tunnel. The beam of her torch caught faded white paint on the wall, an old marker: CAMDEN, letters ghosted under grime. Above it, a newer swirl of something darker. At first glance it looked like graffiti, a rough circle knotted with lines and jagged slashes. Rafi followed her light. "Yeah, that. Hipster Satanism. We can get someone from Gangs to tell us which muppet crew back-tagged an abandoned station." The circle bothered her. The cuts on the chest bothered her. The absence of spray, the neat pool, the lividity. Nothing sat right. "Where did you say you pulled them from." "Through there." He jerked his chin towards the far end of the platform. "Old stairwell. Access from a boarded-up door on the high street, Tyler's mate crowbarred his way in for the video." Harlow stood, her knees cracking as she straightened. She scanned the gravel around the body. Footprints smeared the dust, heavier treads from uniforms, lighter ones, trainers, leading in from the platform. None led away. She nudged Tyler's bare foot with care. Pale. Clean, apart from the grit it had picked up here. "No shoes, no socks. No drag marks. If they moved him, they carried him." Rafi stood as well, brushing grit from his trousers. "You have this air of deep suspicion," he said. "Want to share it with the class." "He did not die where he fell, and I do not like art on walls when the body does not fit the canvas." She turned toward the far end. "Show me the stairwell." They walked along the tracks, torches cutting cones through the stale gloom. Halfway, a gust of cooler air breathed across her face, threaded with a faint scent that did not belong down here, not in a dead station. Not damp, not mould. Something sweet, resinous, like burned herbs. "Smell that." "Kids probably lit incense." Rafi swung his torch up. A line of old enamel adverts clung to the tiles, colours long leached away. Between two of them, fresh chalk scrawled another knot of lines, like the one near the body but drawn in a shaky hand. The air tingled against her skin. A metal cabinet sat open against the wall, long stripped of its original contents. Inside, amid dust and spiderwebs, something glinted brass. Harlow reached in and picked it up. A small compass, pocket-sized, brass casing gone green around the edges with age. The glass face bore no numbers, just a ring of odd etched symbols. The needle shivered as she lifted it, then snapped to point down the tunnel, away from the body. Rafi made a face. "Souvenir from the tourist shop of doom. Put it in a bag, we will add petty theft to the charge sheet for when we nick the mate." She turned the compass in her hand, thumb brushing the sigils. The needle trembled, then jerked, reorienting by a degree. It settled again, unwavering. "I want this logged separately," she said. "Not with personal effects." Rafi snorted. "It is a compass. What, you think he navigated his way to hell with it." She did not answer. The brass felt warm despite the chill in the cabinet. Too warm. They reached the end of the platform. A ragged opening yawned in the tiled wall where engineers had once broken through and then half-heartedly bricked it up. The bricks stopped waist high, leaving a jagged gap where someone had recently knocked the top courses out. Splintered timber lay scattered on the floor, remnants of a door or barrier. Harlow ducked through. On the other side, a steep concrete stairwell dropped away, edges furred with old moss. Fluorescent paint arrows glowed faintly on the walls, remnants of maintenance markings. More recent tags sprawled across them, loops and angular sigils in spray paint. At the bottom, the space opened into a wide, low hall. Her torch swept over rows of abandoned metal frames, like market stalls stripped bare. Dust lay heavy on some surfaces, but elsewhere, tracks cut clean paths. Circular footprints around certain tables, like people had gathered close, shuffled, left. "Place must have hosted a rave at some point," Rafi said. "Wild youth, glow sticks, cheap pills." Yet no cans, no cigarette butts, no glow bracelets. The floor was too clean for a rave. Instead she saw wax drippings on one table, pale stubs clung to the steel, and a blackened circle where something had burned hot. And more of those chalk circles on the concrete, overlapping, half scrubbed away in panic or haste. Some had faded so far she only saw them when she moved her light at an angle. "Have SOCO photographed all the markings." "They are on it." "And you swept the perimeter." "Couple of dead rats, old wiring, nothing fun. This whole place is like a forgotten shopping centre for ghosts." Her torchlight snagged on a lean figure at the far end of the hall, hunched over a circle on the floor, dark curls spilling forward. Round glasses flashed as she looked up, startled by the beam. "Quinn," Rafi said, lowering his light. "Museum sent their pet witch." Eva Kowalski straightened, brushing chalk from her hands. Her worn leather satchel bumped at her hip, bulging with books. The freckles across her nose stood out sharp against skin gone a shade paler than usual. "Occult researcher," she said. "The correct term is occult researcher." Harlow walked toward her. "DCI Norris called you in." "He wanted someone who could tell the difference between graffiti and a ritual diagram." Eva nudged the chalk circle with the toe of her boot. "This is not graffiti." Rafi raised both brows. "Go on then, Professor. Tell us what YouTube coven put on our show." Eva ignored him. "These marks," she said to Harlow, kneeling again, "look like someone tried to copy something they did not fully understand. See the repeated triangle with the split base and the hooked crossbar. Whoever drew this saw the original once, and not for long." "The original." "In a manuscript, maybe." Eva wound a red curl around her finger, then seemed to catch herself and dropped her hand. "Some of the symbols are protective. Others, not. They clash. Like mixing Latin and pretend Latin and then pronouncing it all wrong." "Would it work," Harlow asked. Eva hesitated. "Parts might. If you stand in exactly the worst place." "Tyler Nokes," Harlow said. "Does that name mean anything to the museum." Eva shook her head. "We do not loan grimoires to vloggers." "Then what were they doing here." Rafi wandered off to peer at a rusted metal shutter. "He and his mate come down for some spooky footage, stumble across your half-arsed circle, do a little dance, bleed on it, then one of them drops dead of fear. Simple." "Simple," Harlow repeated. "You said upstairs they entered through one point of access." "Yeah." He called back without turning. "Door on the street. Building site above, hole in the hoarding. Kids squeezed through, went down the stairs, found Aladdin's basement." "And you saw no other exits." "Nothing that was not locked, bricked or rusted solid." Harlow walked the hall's edge, torch grazing the walls. In places, the grime broke, revealing arcs where something large had scraped past. Not recent. Years ago, perhaps. Near the far wall, her light caught a vertical seam in the brickwork, almost invisible, a thin line of mortar discoloured compared to the rest. She stepped closer. The seam ran from floor almost to the ceiling, then vanished under a rusted metal beam. There was no handle, no hinges, but the hair on her neck prickled. She held the compass up. The needle had pointed along the tunnel before. Now, down here, it quivered, then swivelled with purpose, settling to point straight at the seam. "Find that in a Christmas cracker," Eva said softly behind her. "It was in a cabinet by the tracks." Eva slipped her glasses up the bridge of her nose. "The casing. Look at the patina, the sigils. This is not tourist tat. I have seen drawings of something like this in restricted catalogues, years ago. Shade work, they called it. Compass attuned to, ah, thresholds." "Thresholds to what." "It depends who you ask." Rafi laughed, low and sceptical. "You two are killing me. It is a broken compass pointing at a wall. End of story." Harlow pressed her palm against the bricks where the needle aimed. Cold. Solid. No obvious give. Yet the compass held steady in her other hand, as if fixed. "Get me the mate," she said. "I want him to walk me through exactly where they went, what they touched, how they ended up with Tyler on the tracks." "He is still in the van," Rafi said. "Uniform said he threw up on their shoes." "Bring him down. Slowly. Watch his feet." "Watch his feet." "If he avoids anything, any spot on the floor, I want to know." Rafi muttered something under his breath but headed back to the stairs. Eva watched him go, then leaned closer to Harlow, lowering her voice. "This whole space hums," she said. "Like static. Something used to happen here that did not want CCTV." "Human traffic. Drugs. Illegal fights." Harlow let her hand fall from the wall. "Black markets love forgotten places." Eva glanced at the bare metal frames, the wax, the chalk, the half-scrubbed sigils. "Not the kind of market you arrest for counterfeit handbags." "Market for what then." Eva's lips parted, then closed again. She shook her head. "Not my call." "It becomes my call the moment a body drops." Eva chewed the inside of her cheek. "There are stories," she said eventually. "Old ones. Of a market that moves under the city. Not metaphorical, not internet. It appears where the walls thin between, ah, here and there. Trade in things that should not exist." Harlow looked at the compass again. The etched symbols caught her torchlight in a dull gleam. "And this." "That would show you where the wall thins the most." "Convenient." "Or lethal, depending which side you stand on." Boots clanged on the stairs. Rafi's voice carried down, clipped, irritable. "Careful, mind the step. Arms where I can see them. You throw up again and you are cleaning it yourself." Harlow turned. A skinny young man edged into view between two uniforms. Hoodie, torn jeans, hands cuffed in front of him. His trainers left faint prints in the dust as he shuffled. He refused to look at the tables, at the chalk marks, at the body that lay somewhere up the tunnel. His eyes tracked the floor like he expected it to bite. "Tyler's mate," Rafi said. "Meet Liam Joyce, star witness and possible grade A idiot." Liam swallowed hard. "I did not kill him," he said at once. "I swear, I did not, I did not touch him." "Good," Harlow said. "Then this will be easy. You will retrace your steps. Where you came in, where you walked, where you stood, what you saw him do. If you lie, I will know." He flicked a panicked look at Eva. "There was no witch stuff," he said. "We just came down for a video. Couple of torches, bit of a laugh. Ty loved this freaky shit but it was just content, you know, clickbait. We did not summon anything." "Start at the door," Harlow said. "Show me." He balked. "Do we have to be here, like, now." "Yes." He squeezed his eyes shut for a heartbeat, then opened them and started forward. The uniforms flanked him, Rafi slightly ahead, his torchbeam bouncing. Liam stepped carefully, skirting one circle of faint chalk, then another, without seeming to register he did it. When they reached the centre of the hall, he veered, unprompted, away from the place where wax pooled thickest. Eva's breath hissed between her teeth. "You see," she murmured. Harlow watched his feet. Every twitch, every shift of weight. Near the far wall, four paces from the seam, he stopped dead. His shoulders bunched. "Carry on," Harlow said. He shook his head. "I am not going near that bit." "What bit." "That." His cuffed hands jerked toward the blank, dirty concrete in front of him, nowhere in particular. "It felt wrong. Last night. Like walking into a freezer at the back of my skull. I told Ty we should not. He laughed. Said it would look sick on camera." "Did he walk there," Harlow asked. Liam nodded, rapid, reluctant. "He stepped right up to it. To, like, show off. Leaned, I do not know, leaned on the wall. Then he jerked. Sort of, like, double vision, like he was in two places at once, then he, he, he just, vanished. For a second. Then he was back and he fell. There was blood on his chest. I thought it was a joke. Then he would not get up." Eva's fingers dug into the strap of her satchel. "Harlow." Harlow lifted the compass. The needle spun, wild now, whipping the full circle then snapping back to the seam so hard the thin metal quivered. A low tremor shuddered through the floor, so brief she might have imagined it. Dust sifted from the ceiling in a thin veil. "Brick walls do not make people vanish," Rafi said, but his voice had lost some of its easy mockery. The mortar line in front of Harlow darkened, as if damp spread from within. A faint crackle tickled her palm, like static discharging. The compass grew hot in her hand. Liam yelped. "The wall," he choked. "It is doing it again." A hairline fracture chased itself up the brick, a pale thread that glowed for a heartbeat, then split wider. Air rushed out, cold and sharp as old stone in winter. Harlow stepped back as the first brick shuddered, bulged, then slipped forward with a dull, decisive thud onto the floor.
