You are an expert and award-winning novel writer in the dark Thriller genre. Your readers are hooked on your stories and can't wait to read the book you have in store. <important> - MUST: Start each chapter in medias res (in the middle of action). AVOID talking about the weather, time of day, the position of the sun, or other boring stuff. - The instructions/summary are just a that, a summary. Feel free to add details, stretch sections and add interesting transitions/descriptions/fillers. - When called for it, have fast-paced action, but otherwise take things slow. This is an experience, and not for people with short attention spans. Enjoy the wine, not slurp Red Bull. - Add descriptions when transitioning places/times/etc, or when coming by new places (e.g. a corner shop, a cafe, etc.). But remember: NOT at the start or end of a chapter. - MUST: AVOID ending in internal monologue, reminiscing or waiting for the next day. A good chapter end is when we're ending right when shit hits the fan. We want to have the reader be excited for what comes next. So no reminiscing, contemplating or summarizing the day. It's popcorn time! </important>

It was time to go to the store.</good> - Avoid redundant adverbs that state the obvious meaning already contained in the verb: - <bad>She whispered quietly to her mom.</bad> - <good>She whispered to her mom.</good> - Use stronger, more descriptive verbs over weak ones: - <bad>Daniel drove quickly to his mother's house.</bad> - <good>Daniel raced to his mother's house.</good> - Omit adverbs that don't add solid meaning like "extremely", "definitely", "truly", "very", "really": - <bad>The movie was extremely boring.</bad> - <good>The movie was dull.</good> - Use adverbs to replace clunky phrasing when they increase clarity: - <bad>He threw the bags into the corner in a rough manner.</bad> - <good>He threw the bags into the corner roughly.</good> - Avoid making simple thoughts needlessly complex: - <bad>After I woke up in the morning the other day, I went downstairs, turned on the stove, and made myself a very good omelet.</bad> - <good>I cooked a delicious omelet for breakfast yesterday morning.</good> - Never backload sentences by putting the main idea at the end: - <bad>I decided not to wear too many layers because it's really hot outside.</bad> - <good>It's sweltering outside today, so I dressed light.</good> - Omit nonessential details that don't contribute to the core meaning: - <bad>It doesn't matter what kind of coffee I buy, where it's from, or if it's organic or not—I need to have cream because I really don't like how the bitterness makes me feel.</bad> - <good>I add cream to my coffee because the bitter taste makes me feel unwell.</good> - Always follow the "show, don't tell" principle. For instance: - Telling: <bad>Michael was terribly afraid of the dark.</bad> - Showing: <good>Michael tensed as his mother switched off the light and left the room.</good>- Telling: <bad>I walked through the forest. It was already Fall, and I was getting cold.</bad> - Showing: <good>Dry orange leaves crunched under my feet. I pulled my coat's collar up and rubbed my hands together.</good>- Add sensory details (sight, smell, taste, sound, touch) to support the "showing" (but keep an active voice) - <bad>The room was filled with the scent of copper.</bad> - <good>Copper stung my nostrils. Blood. Recent.</good> - Use descriptive language more sporadically. While vivid descriptions are engaging, human writers often use them in bursts rather than consistently throughout a piece. When adding them, make them count! Like when we transition from one location to the next, or someone is reminiscing their past, or explaining a concept/their dream... - Avoid adverbs and clichés and overused/commonly used phrases. Aim for fresh and original descriptions. - Avoid writing all sentences in the typical subject, verb, object structure. Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. Like so: <good>Locked. Seems like someone doesn't want his secrets exposed. I can work with that.</good> - Convey events and story through dialogue. It is important to keep a unique voice for every character and make it consistent. - Write dialogue that reveals characters' personalities, motivations, emotions, and attitudes in an interesting and compelling manner - Leave dialogue unattributed. If needed, only use "he/she said" dialogue tags and convey people's actions or face expressions through their speech. Dialogue always is standalone, never part of a paragraph. Like so: - <bad>"I don't know," Helena said nonchalantly, shrugging her shoulders</bad> - <good>"No idea" "Why not? It was your responsibility"</good> - Avoid boring and mushy dialog and descriptions, have dialogue always continue the action, never stall or include unnecessary fluff. Vary the descriptions to not repeat yourself. Avoid conversations that are just "Let's go" "yes, let's" or "Are you ready?" "Yes I'm ready". Those are not interesting. Think hard about every situtation and word of text before writing dialogue. If it doesn't serve a purpose and it's just people talking about their day, leave it. No one wants to have a normal dinner scene, something needs to happen for it to be in the story. Words are expensive to print, so make sure they count! - Put dialogue on its own paragraph to separate scene and action. - Use body language to reveal hidden feelings and implied accusations- Imply feelings and thoughts, never state them directly - NEVER use indicators of uncertainty like "trying" or "maybe" - NEVER use em-dashes, use commas for asides instead </styleGuide> <voiceGuide> Each character in the story needs to have distinct speech patterns: - Word choice preferences - Sentence length tendencies - Cultural/educational influences - Verbal tics and catchphrases Learn how each person talks and continue in their style, and use their Codex entries as reference. <examples> - <bad>"We need to go now." "Yes, we should leave." "I agree."</bad> <good>"Time's up." "Indeed, our departure is rather overdue." "Whatever, let's bounce."</good> - Power Dynamic Example: <bad> "We need to discuss the contract." "Yes, let's talk about it." "I have concerns." </bad> <good> "A word about the contract." "Of course, Mr. Blackwood. Whatever you need." "The terms seem..." A manicured nail tapped the desk. "Inadequate." "I can explain every-" "Can you?" </good> </examples> </voiceGuide> <dialogueFlow> When writing dialogue, consider that it usually has a goal in mind, which gives it a certain flow. Make dialogue sections also quite snappy in the back and forth, and don't spread the lines out as much. It's good to have details before, after, or as a chunk in-between, but we don't want to have a trail of "dialogue breadcrumbs" spread throughout a conversation. <examples> - Pattern 1 - Question/Deflection/Revelation: <good> "Where were you last night?" "Work. The usual." "Lipstick's an interesting shade for spreadsheets." </good> - Pattern 2 - Statement/Contradiction/Escalation: <good> "Your brother's clean." "Tommy doesn't touch drugs." "I'm holding his tox screen." </good> - Pattern 3 - Observation/Denial/Truth: <good> "That's a new watch." "Birthday gift." "We both know what birthdays mean in this business." </good> - Example - A Simple Coffee Order: <bad> "I'll have a coffee." "What size?" "Large, please." </bad> <good> "Black coffee.""Size?""Large. Been a long night." "That bodega shooting?" "You watch too much news." "My brother owns that store." </good> This short exchange: - Advances plot (reveals connection to crime) - Shows character (cop working late) - Creates tension (unexpected connection) - Sets up future conflict (personal stake) - Example - Dinner Scene: <bad> "Pass the salt." "Here you go." "Thanks." </bad> <good> "Salt?" "Perfect as is. Mother's recipe." "Mother always did prefer... bland things." "Unlike your first wife?" </good> - Example - Office Small Talk: <bad> "Nice weather today." "Yes, very nice." "Good for golf." </bad> <good> "Perfect golf weather." "Shame about your membership." "Temporary suspension. Board meets next week." "I know. I called the vote." </good> </examples> </dialogueFlow> <subtextGuide> - Layer dialogue with hidden meaning: <bad>"I hate you!" she yelled angrily.</bad> <good>"I made your favorite dinner." The burnt pot sat accusingly on the stove.</good> - Create tension through indirect communication: <bad>"Are you cheating on me?"</bad> <good>"Late meeting again?" The lipstick stain on his collar caught the light.</good> <examples> - Example 1 - Unspoken Betrayal: <bad> "Did you tell them about our plans?" "No, I would never betray you." "I don't believe you." </bad> <good> "Funny. Johnson mentioned our expansion plans today." "The market's full of rumors." "Mentioned the exact numbers, actually." The pen in his hand snapped. </good> - Example 2 - Failed Marriage: <bad> "You're never home anymore." "I have to work late." "I miss you." </bad> <good> "Your dinner's in the microwave. Again." "Meetings ran long." "They always do." She folded the same shirt for the third time. </good> - Example 3 - Power Struggle: <bad> "You can't fire me." "I'm the boss." "I'll fight this." </bad> <good> "That's my father's nameplate you're sitting behind." "Was." "The board meeting's on Thursday." </good> </examples> </subtextGuide> <sceneDetail> While writing dialogue makes things more fun, sometimes we need to add detail to not have it be a full on theatre piece. <examples> - Example A (Power Dynamic Scene) <good> "Where's my money?" The ledger snapped shut. "I need more time." "Interesting." He pulled out a familiar gold pocket watch. My mother's. "Time is exactly what you bargained with last month." "That was different-" "Was it?" The watch dangled between us. "Four generations of O'Reillys have wound this every night. Your mother. Your grandmother. Your great-grandmother.Shall we see who winds it next?" </good> - Example B (Action Chase) It's much better to be in the head of the character experiencing it, showing a bit of their though-process, mannerisms and personality: <good> Three rules for surviving a goblin chase in Covent Garden: Don't run straight. Don't look back. Don't let them herd you underground. I broke the first rule at Drury Lane. Rookie mistake. The fruit cart I dodged sailed into the wall behind me. Glass shattered. Someone screamed about insurance. *Tourist season's getting rough*, the scream seemed to say. Londoners adapt fast. "Oi! Market's closed!" The goblin's accent was pure East End. They're evolving. Learning. I spotted the Warren Street tube station sign ahead. *Shit.* There went rule three. </good> - Example C (Crime Scene Investigation) <good> "Greek." Davies snapped photos of the symbols. "No, wait. Reverse Greek." "Someone's been watching too many horror films." I picked up a receipt from the floor. Occult supply shop in Camden. Paid by credit card. *Amateur hour*. "Could be dangerous though," Davies said. "Remember Bristol?" "Bristol was Sanskrit. And actual cultists." I pointed to the nearest symbol. "This genius wrote 'darkness' backwards but used a Sigma instead of an S. It's summoning Instagram followers at best." "Speaking of followers..." Davies pointed to heavy foot traffic in the dust. Multiple sets. All new trainers. *Ah.* "Anyone check local uni paranormal societies?" </good> - Example D (Dialogue-heavy) <good> "Found your card in her wallet." The detective slid it across the table. Worn edges. Folded corner. Three years old at least. "Standard practice. I work missing persons." "Funny thing about missing persons.Eventually they stop being missing. Turn up in the Thames. Under motorways. In pieces." "I don't-" "You found four last year. All breathing." She opened a file. "This would've been your first dead one. If we hadn't found her first." The card felt heavier somehow. </good> </examples> </sceneDetail> <sceneOpenings> KEY RULE: Never open with more than one paragraph of description, no matter how beautiful. Description should be earned through action and dialogue. Instead of opening with setting description, open with: - A character doing something specific - A line of dialogue that raises questions - An unexpected observation - A moment of tension or conflict - Start with a hook that's 1-2 sentences maximum - Follow with a smaller paragraph that provides immediate context - Vary paragraph size from the start to create visual interest </sceneOpenings> </proseGuidelines> Write a chapter based on the following instructions: <instructions> Write a fully fleshed out scene of at least 1000 words in the thriller genre. A detective is pursuing a suspect through rain-soaked city streets at night. The chase takes them from the street level down into an underground market. The detective must decide whether to follow the suspect into unfamiliar and potentially dangerous territory. Use the codex entries above as your world reference for characters and setting. Only include the prose of the scene without any markdown or commentary. </instructions>

The suspect vaulted the taxi barrier and slammed shoulder-first into a cyclist, sending the man and his takeaway curry skidding across the pavement. Detective Harlow Quinn cleared the same barrier a breath later, boots splashing through oily water, warrant card clenched in one fist and baton in the other. “Met Police. Move.” People moved. Not fast enough. The man ahead glanced back, and the green glow from The Raven’s Nest sign cut across his face. Olive skin. Short curly dark hair plastered to his forehead. Warm brown eyes gone flat with panic. Tomás Herrera. Former paramedic. Unlicensed, off-book, connected to three bodies that had turned up with strange burn marks under their ribs. He was faster than he looked. Quinn drove through the knot of smokers outside the Soho bar. Someone cursed as she clipped an elbow. Behind her, The Raven’s Nest pulsed green through the rain, its doorway half-choked by drinkers who knew when to look away. Old maps and black-and-white photographs covered the walls inside, she knew that much. She had watched the place for six weeks and had never once seen the same crowd enter twice. Herrera had come out of a hidden back room behind a bookshelf with blood on his cuff and a little white bone token between his fingers. Now he ran. He cut left into an alley narrow enough to scrape both shoulders, and Quinn followed with her baton raised. Bins stank of stale beer, bleach and rotting citrus. Rain drummed on metal lids. A rat shot across her path and vanished under split cardboard. Herrera kicked a bin behind him. Quinn twisted sideways. The bin clipped her thigh and spun away, vomiting black bags over the ground. Pain flared high and hot, but she kept her stride. Military precision had survived worse than Soho refuse. “Herrera.” He did not slow. “You’ve got nowhere clever to go.” “Then stop following, detective.” His accent carried Spain under London, warm vowels sharpened by fear. He vaulted a low wall at the alley’s end. Quinn planted one boot on a crate, caught the slick brick edge, and hauled herself over. Her worn leather watch scraped stone on the way down. The drop on the far side jarred her knees. Herrera sprinted across a service yard and shoved through a fire door into a restaurant kitchen. Quinn hit it before it swung shut. Heat slapped her. Oil spat in pans. A cook yelled as Herrera knocked over a tray of raw pink prawns and sent them sliding across white tiles. Quinn’s boot skidded. She grabbed a steel prep table, steadied herself, and saw him ram through the front of the restaurant. “Police.” A waiter froze with a tower of plates in his hands. “Back door?” He pointed with his chin. “Front. He went front.” Quinn shoved past red paper lanterns and startled diners. Someone had ordered noodles with chilli; the sharp scent hung in the air with garlic and burnt sugar. Herrera smashed through the door into the street, and the bell above it gave one bright little scream. Outside, traffic crawled under broken reflections. Headlights smeared across the wet road. Horns barked. A bus hissed at the kerb. Herrera darted between two taxis, slapped the bonnet of a black cab, and climbed over it when the driver braked too late. Quinn went round. “Oi, love, you dent that and I’ll have your pension.” “Invoice the Crown.” She passed close enough to see the cabbie’s mouth open for more, then she lost him in the rain and engine fumes. Herrera ran north. Not random. Quinn saw it in the way he chose gaps before they opened, in the way he avoided bright shopfronts, in the way his right hand kept checking his coat pocket. The bone token. He had somewhere to spend it, or someone to pay. Her radio crackled at her shoulder. “Quinn, status.” She pressed the transmit button without breaking pace. “Foot pursuit. Male suspect, Tomás Herrera, heading north from Soho. Request units at Tottenham Court Road and Camden approaches.” “Camden?” “He’s not shopping.” A pause. Paper rustled on the other end, some poor night sergeant hunting maps and procedure. “Do you require armed support?” Quinn remembered DS Morris in a locked warehouse three years ago, his service weapon unfired, his face grey, every mirror in the room cracked from the inside. She remembered the report that called it gas exposure because paperwork liked clean lies. “Negative. Keep uniforms wide. Do not engage alone.” Herrera threw a look back at that. Too sharp. He knew she had said it for him. He cut into Charing Cross Road, then down into the Underground entrance. Quinn followed him past the ticket barriers. One commuter protested when Herrera jumped the gate and clipped his briefcase. Quinn slapped her warrant card against the glass as she vaulted the barrier beside it. “Met Police.” The staff member in the booth recoiled and hit a button. Somewhere, a gate beeped in delayed approval. Down the escalator, Herrera took the left side three steps at a time. Quinn kept close, one hand sliding along the moving rail, baton folded against her wrist. Posters flashed by. Musicals. Perfume. A missing cat with a torn corner. The station smelt of wet wool, brake dust and hot electrics. A train screamed below. Herrera reached the platform as the doors began to close. He forced his hand between them. The doors bounced open. He slipped in. Quinn lunged. A woman with a pram blocked the gap. “Move.” “I can’t, the wheel’s stuck.” Quinn hooked the pram frame, lifted, and shoved it clear with more force than grace. The mother gasped. The doors chimed again. Herrera stood inside the carriage, chest heaving, one hand on the pole, the other pressed over his coat pocket. Rain ran off him onto the rubber floor. His Saint Christopher medallion had worked free from his collar and gleamed at his throat. Quinn reached the doors. Herrera looked straight at her and held up the bone token between two fingers. The doors shut in her face. For half a second they stared at each other through smeared glass. His expression shifted, not triumph. Warning. Then the train pulled away. Quinn struck the door with the flat of her palm. “Control, suspect boarded northbound Northern line.” “Received. British Transport Police notified.” “Tell them not to box him in.” “Say again?” “Do not box him in.” The train vanished into the tunnel with a deep metal roar. Quinn turned. At the far end of the platform, a maintenance gate stood ajar. A smear of wet footprints led to it. She looked back at the tunnel. Herrera had boarded the train. Herrera had also left tracks at a gate he had never reached. The token. Quinn crossed the platform against the flow of commuters. A busker stopped playing mid-song as she passed. The maintenance gate had a padlock hanging from it, open, its shackle blackened as though someone had heated it with a torch. Beyond lay a tiled service corridor lit by yellow bulbs. Her radio snapped. “Quinn, stay visible. BTP can intercept at Camden Town.” “He’s left the public line.” “Left how?” “Unclear.” “That is not a location.” “No. It’s a problem.” She ducked through the gate. The corridor swallowed the station noise within ten steps. Tiles gleamed with damp. Old pipes ran along the ceiling, thick with flaking paint. The air cooled and took on the mineral taste of deep concrete. Her footsteps sounded too loud. After forty metres the corridor forked. No footprints on the left. Three wet marks on the right, then none. Quinn crouched. The floor beyond had a thin dusting of grey grit. Undisturbed. She touched the last wet mark. Water. Real enough. The right-hand passage ended at an old service lift with concertina doors. Its sign read OUT OF USE in faded red letters. Someone had scratched a mark into the metal panel beside it, a small circle bisected by a line. Beneath the scratch, a narrow slot had been cut into the wall, too thin for a key, the right size for a coin. Or bone. Quinn’s jaw tightened. “Herrera.” The lift clunked. She stepped back, baton up. The doors did not open. Instead, the wall to her left sighed, and a seam appeared where no seam had been. Damp air rolled out. It carried incense, blood, frying meat and a bitter chemical bite that coated the back of her tongue. A stairwell descended into darkness. Quinn unclipped the torch from her vest and aimed it down. The beam reached twelve steps, then failed. Not faded. Failed. As if the dark had weight. Her radio hissed, then dropped to static. “Control.” Static. “Quinn to Control.” A child laughed below. No child should have been below. Quinn took one step down. The stairs felt old. Older than the Tube. The tiles changed to brick, then to stone blocks worn concave in the centre. Scraps of paper clung to the walls. Not posters. Notices in languages she knew and others that made her eyes want to slide away. Prices. Warnings. Names crossed out with brown ink. Halfway down, a man sat on an upturned crate, blocking the stairs. He wore a long navy coat, a flat cap and no shoes. His feet looked pale and soft, the nails painted black. A brass bowl rested in his lap. Inside it lay teeth, coins, buttons, a dried beetle and three white bone tokens like the one Herrera had carried. “No badge below.” His voice had a North London lilt wrapped around something older. Quinn held up her warrant card. “This badge goes where I go.” He peered at it, then laughed through teeth too small for his mouth. “That little card has no crown down here.” “Tomás Herrera came through.” “Lots of men come through. Some go out.” “Did he pay you?” The man tapped the brass bowl with one black nail. Tick-tock. Tick-tock. “Entry costs bone.” “I don’t have one.” “Everyone has bone.” Quinn let the silence sit between them. Her baton remained low, not hidden. His gaze dropped to it, then to her watch. “Old leather. Dead animal. Counts for nothing.” “You spend much time annoying police?” “Police spend no time here.” He leaned forward and sniffed the air near her sleeve. “Except one, years ago. He cried red.” Morris. Quinn’s grip tightened before she could stop it. The man smiled as if he had tasted the movement. “Move.” “No token.” She took one step closer. “You know what happens if I drag you up those stairs?” “You find the stairs gone.” He tapped the bowl again. Tick-tock. Above her, concrete groaned. The open seam in the wall narrowed by an inch. Quinn checked her watch. Force of habit. The cracked face showed the second hand juddering backwards. Her pulse hit once, hard. “Name your price.” The man’s smile faded into business. “Memory. Small one. First dog. First kiss. Mother’s voice. We take clean.” “No.” “Blood, then. Not much.” He lifted the bowl. The beetle inside clicked its legs against brass. Quinn extended her left hand. The worn leather strap brushed her wrist bone. With her right, she drew a compact folding knife from her pocket, the sort she had carried since uniform days when London still let her believe locks and blades were the worst of it. She cut the pad of her thumb and squeezed. Three drops hit the bowl. The teeth chattered. The man inhaled like a smoker after a week without. “Detective Harlow Quinn.” She had not given her name. “Step soft, Harlow Quinn. The Veil Market dislikes honest shoes.” He moved aside. She descended. The last step delivered her into an abandoned Tube station beneath Camden that no map admitted. The platform stretched under a vaulted roof stained with soot and age. Tracks lay buried beneath planks and carpets. Stalls crowded both sides, built from theatre flats, church doors, corrugated tin and polished mahogany counters that belonged in old banks. Lamps burned blue and green behind coloured glass. Cages hung from hooks. Things inside them whispered in voices that belonged to sleeping people. The market breathed. Vendors called over one another in low tones. A woman with silver pins through her lips weighed black powder on a scale made of finger bones. Two men in tailored suits argued over a jar filled with pale eyes. An elderly Sikh gentleman sold umbrellas from a neat stand, each canopy stitched with constellations that shifted when Quinn looked away. The smell hit in layers: wet stone, cardamom tea, formaldehyde, hot sugar, singed hair. No one stared for long. That bothered her more than staring. Quinn kept to the edge, baton hidden against her thigh. Her brown eyes scanned hands first, exits second, faces third. Old habits. Good habits. Her cropped salt-and-pepper hair clung close to her skull. Rainwater crawled down the back of her collar. A sign above the platform read CAMDEN ROAD, though Camden Road had never had platforms this deep. Herrera moved through the crowd ahead, limping now. He had ditched his coat. His grey shirt stuck to his back, and the scar along his left forearm showed when he pushed past a stall hung with tiny brass bells. His medallion flashed as he turned his head. He saw her. His mouth formed a word. No. Then he ran again. Quinn shoved after him. A vendor hissed as she knocked a bowl of glass beetles from a table. They burst across the floor, wings rasping like paper razors. One sliced her trouser leg. Another leapt for her face. She swatted it aside and felt it cut her knuckle. “Police. Out of my way.” The market went quiet in sections, like lights shutting off down a corridor. Herrera ducked beneath a hanging red curtain. Quinn followed and found herself in a narrow aisle lined with bottles. Each bottle held a different coloured liquid, and each liquid moved against the glass as if it wanted out. A small woman in a fox-fur stole blocked the aisle. “No running near the tinctures.” Quinn lifted her warrant card again. The woman’s eyes clouded white. “Poor little paper shield.” Herrera grabbed a bottle from the stall and hurled it at the ground. The glass shattered. A thick yellow vapour erupted. It smelt of lemons and opened graves. Quinn clamped one hand over her mouth and drove through it. Her eyes watered. Shapes doubled. The aisle stretched, then snapped back. Herrera had reached a set of iron stairs leading down from the platform edge to the old tracks. “Herrera, stop.” He did. That stopped her as well. He stood halfway down, one hand gripping the rail, the other pressed against his ribs. Blood seeped between his fingers. Not from the chase. Older. Darker. “You shouldn’t have come.” “People keep saying that.” “They’ll cut you up for parts before your lot find the gate.” “My lot know where I am.” “No, detective. They know where you stopped being.” Behind Quinn, the market had gone silent. Herrera looked past her shoulder. His face lost colour. Quinn turned. Detective Harlow Quinn had seen armed robbers, bomb scenes, drowning victims, children who lied better than MPs, and one warehouse full of mirrors that screamed without mouths. None of it helped. A tall figure walked down the aisle towards her wearing a beautiful long black Victorian mourning coat. Its face had the smooth blankness of an unmarked egg, except for a vertical mouth full of copper needles. In one gloved hand it carried Quinn’s radio, still crackling with dead static. In the other, it held her warrant card. She looked down. Her hand held nothing. The faceless thing stopped three paces away and tilted its head. “No badge below.” Herrera bolted down the iron stairs. Quinn lunged after him, but the thing opened its needle mouth and spoke in DS Morris’s voice. “Harlow, don’t let it touch your watch.” The leather strap on her left wrist tightened like a noose. Then something beneath the platform began to climb.
