You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The abandoned Tube station stank of mildew and something sweeter underneath, like fruit left too long in a bowl. Detective Harlow Quinn ducked beneath the police tape and let her torch sweep across the tiled wall. Victorian brickwork. A platform sign half-buried under a century of grime: SOUTH KENTWORTH. She hadn't known the station existed until the call came through at half past four in the morning. "Watch your step on the stairs, Guv." DC Patel stood at the bottom of the platform stairwell, gloved hands tucked into his jacket. Behind him, the forensics team worked under portable floodlights that turned the curved ceiling into a bone-white dome. "Who found him?" "Urban explorer. Kid with a camera. He's upstairs with Mallory, shaking like a leaf and asking for his solicitor." "Let him shake. What have we got?" Patel led her along the platform. The body lay just beyond the second floodlight, arranged on his back with his arms crossed over his chest like a figure on a tomb. Male, mid-thirties, expensive shoes, a coat that cost more than Quinn's monthly rent. No visible wounds. His eyes were open and fixed on the tiled ceiling, and the whites were threaded through with tiny red branches, as though every capillary had burst at once. "DS Okonkwo says it looks like a heart attack. Maybe a stroke." Quinn crouched beside the body. Her knees complained. She pressed the back of her glove to the man's cheek, then lifted his hand and let the weight of it settle again. "How long has he been down here?" "Doctor reckons eight hours, ten at the outside. Rigor's just coming off." "And no one noticed a man in a three-thousand-pound coat wandering into a sealed station at rush hour." "The entrance is behind a maintenance hoarding on Gloucester Road. You'd have to know it was there." Quinn grunted. She moved her torch slowly across the body. Something snagged at her, a pressure behind her ribs that wouldn't settle. Eighteen years in the job taught you to trust that pressure, even when you couldn't name it. DS Ben Okonkwo came up behind them, tablet in hand. Broad shoulders, kind face, a tie loosened against the damp. "Morning, Harlow. Or evening, depending. I've sent prelims to the coroner. Cardiac event, most likely. No sign of assault. No defensive wounds. His wallet's still in his pocket with four hundred quid and a black Amex." "So he walked down here, lay down on his back with his arms arranged like Sir Lancelot, and had a heart attack." "People do strange things when they're dying. Disorientation, oxygen deprivation to the brain. I've seen a jumper fold his jacket before he went off the roof." "Folding a jacket is strange. This isn't strange. This is staged." Okonkwo crouched on the opposite side of the body. "Staged by who? There's no one else's prints on him, no drag marks, nothing on CCTV from the street entrance. The lock on the hoarding wasn't forced. He came in alone." "Then show me how he lay down." "Sorry?" "If he collapsed, show me the mechanics. A man has a cardiac event, he clutches his chest, he goes down. He lands how he lands. He doesn't cross his arms over his sternum and close his ankles." Okonkwo looked at the corpse. He sighed. "All right. Post-mortem muscular contraction. It happens." "Not symmetrically. Not like that." Quinn stood. She paced a slow circle around the body, letting her torchlight crawl across the tiles. She paused at the dead man's feet and crouched again. "Ben." "What?" "Look at the dust." Fine grey dust coated the platform like a layer of old talcum. Footprints cut through it — hers, Patel's, the forensics team's, the explorer's tread from earlier in the night. But around the body itself, the dust lay undisturbed in a neat oval, except for one set of prints leading in and stopping beside the dead man's right shoulder. They didn't lead out again. "Someone walked to him and didn't walk away." "Or he walked in and lay down." "Then where are his own prints? He's wearing Italian leather soles with a distinctive pattern. I can see yours from here, Ben, and you've been over by the wall." She shone the torch at the prints beside the shoulder. "These are bare feet." Okonkwo leaned closer. The impressions in the dust were narrow, long-toed, and the weight distribution was strange — as though whoever made them walked on the balls of their feet without ever letting their heel come down. "Could be the explorer," he offered. "The explorer was wearing hiking boots. Patel has the photos." "Then someone else was down here. Fine. But that doesn't change cause of death." "It changes everything about cause of death." She stood and moved to the wall, where the tiles had lost their glaze in patches and the grout had gone black. Her torch caught something at knee height. A smear. Not blood — too dark, almost oily, and it drank the light instead of reflecting it. She didn't touch it. She didn't want to touch it. "Ben, come and look at this." He joined her. He saw the smear. He saw nothing unusual. "Grease. Old tunnel's full of it." "Smell it." "I'd rather not." "Smell it, Sergeant." He bent closer and drew a careful breath. His face did something complicated. "That's the fruit smell. From when we came in." "It's coming off the wall." She stepped back. "It's coming off him, too. I noticed it when I checked his cheek." Okonkwo straightened slowly. "Harlow." "Don't." "Three years ago." "Don't." "When Morris died, you started seeing patterns that weren't—" "Morris died in a locked room with the lights still on and no exit wounds and no entry wounds and a look on his face like he'd watched the world end." Her voice didn't rise. It went flatter, harder, the way a blade does on a whetstone. "And every senior officer in the building told me I was seeing patterns that weren't there. I stopped arguing because I wanted to keep my job. I'm not stopping tonight." She turned back to the body. The dead man stared up at the curved ceiling with his burst-capillary eyes, and Quinn crouched one more time and really looked at him — at the way his coat lay too flat across his chest, at the faint powder on his lips that wasn't drug residue, at the small mark on the inside of his left wrist that she'd mistaken, at first, for a birthmark. It was a symbol. A circle bisected by a wavy line, the line ending in three small hooks. She'd seen it before. On a photograph pinned to the inside of DS Morris's desk drawer, the drawer she'd cleaned out herself three years ago and never quite emptied into the box she was meant to put it in. "Ben." "Yeah." "Get Patel to photograph his left wrist. Close as the camera will go. And don't log it in the shared file. Send it to my personal email." Okonkwo was quiet for a long moment. Then he nodded, just once, and went to find Patel. Quinn stayed where she was, crouched by the body, the fruit-sweet smell curling at the back of her throat. The pressure behind her ribs had become something colder and more specific. She turned her torch off and let the floodlights do their work from twenty feet away, and in the dimness she thought she saw, for half a second, the dust near the dead man's crossed wrists stir as if something had exhaled close to the ground. She watched until the dust went still again. Then she stood up, and reached for her notebook, and began to write.
