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 rain followed Harlow Quinn down Camden Road and quit at the cordon. She ducked the tape, badged the PC stamping his feet by the hoarding, and looked up at what remained of South Kentish Town station. Oxblood tiles behind plywood. A pale scar where the roundel had hung until somebody prised it off. A dead mouth of a doorway, sealed since 1924 and open tonight. "Stairs are dodgy, guv. No power past the gate." The PC passed her a torch. "Body's on the eastbound platform. What's left of a platform." "Who found him?" "Anonymous call, 3:40 this morning. No number withheld. Just gone." She took the stairs one at a time, torch low, and counted the dust. It lay on the treads like grey felt, unbroken until the boots of the first response crew. One set down, one set up. Nobody else. She filed that. DS Hodge waited at the bottom, eating a cereal bar with the reverence of a man who'd been awake since four. "White male, mid-thirties, no wallet ID, no phone that'll switch on." He jerked his chin down the passage. "Urban explorer, is my bet. They love this place. Heart gives out, mate does a runner, rings it in from a call box out of guilt. Happens more than you'd think." "Who strips copper?" "Not a mark on the cabling. I checked." "Then he wasn't thieving." She stepped past him onto the platform. The dead man lay on his back six yards from the bricked arch at the tunnel end, arms at his sides, arranged the way sleepers arrange themselves. Good coat. Brogues polished to a funeral shine. No blood, no swelling, no foam at the lips. His hair had gone white in a streak at both temples, so clean it looked dyed. His eyes were open and filmed grey, like a fish left on ice. "Forties, I'd say," Hodge offered. "Maybe the white's natural." "His driver's licence photo would settle it. If we had his wallet." "Ah." Hodge scratched his neck. "Wallet's there. Cash in it. Eighty quid. Cards gone, ID gone, money left." "So not robbery." Quinn crouched. "Somebody took his name and left his eighty pounds. That's not a thief, Hodge. That's an editor." The man's right fist was closed. She eased the fingers back with a gloved hand. A knuckle of bone sat in the palm, polished yellow, drilled through the middle, a symbol cut into one face — an eye inside a keyhole, or a keyhole inside an eye. "Game piece," Hodge said. "Dice or something." "Dice have six faces." She bagged it herself. Under the body's left shoulder, the torch caught green metal. She worked it free: a small brass compass, crusted with verdigris, its face etched ring on ring with marks too fine to read in this light. The needle did not point up the passage toward north. It dragged, quivering, toward the bricked arch. "Broken," Hodge said. "Compasses don't break toward a wall." He had no answer for that, so she gave him the courtesy of changing the subject. "Ticket hall?" "This way. You're going to love it." The old booking hall stank of candle wax and wet chalk. Collapsible tables stood folded and stacked in ordered rows against the tiled wall. The floor bore a grid of chalked squares, each the size of a market pitch, most scuffed to ghosts. Twine ends and candle stubs and a single torn page lay in the corners, columns of figures in brown ink, a heading in a script Quinn had never seen. "Car boot for nicked goods," Hodge said, warming to it. "Fences rent the pitches. Someone got greedy, fell out over the takings." "Raves leave bottles. Fences leave fag ends. This place was swept." "So they were tidy criminals." "They cleared fifty stalls out of a sealed station in the dark and left one man behind on the platform." She turned the torn page in its bag. "That's not a fallout over takings. That's a closing time." Back on the platform she found the ring. Six feet across, scorched into the tile between the dead man's head and the arch — except scorched was the wrong word. The glaze had run and reset like toffee, shiny as poured glass, and when she held her palm an inch above it the cold rose to meet her skin. No soot. No accelerant. The air over it smelled the way platforms smell before a storm breaks, all metal and charge. "Thermite," Hodge said. "Kids. Internet challenge." "Kids with polish and brogues?" Her watch caught her eye. The second hand had stalled, shuddering against the twelve, four seconds, five, then jumped to catch up. She stood very still. Three years since she'd watched a dead man's watch do that on a mortuary tray while a coroner said the word misadventure with his jaw tight, and nobody, not the coroner, not the Met, not Quinn herself, had ever explained the ozone smell in that locked room, or what Morris's face had been looking at. She put it away. Filed it with the dust. "Guv." The PC from topside leaned down the stairwell. "Woman at the cordon. Found her at the gap in the hoarding with a notebook. Says she's British Museum." The woman sat on a fold-up stool a uniform had given her, red curls flattened by the drizzle, round glasses spotted with rain. Freckles. A satchel of books worn soft at the corners, a museum pass on a lanyard. "Eva Kowalski. I work in the restricted archives." She tucked a strand of hair behind her left ear. "I document disused stations. Tiles, signage. It's legitimate — I can show you the project approval." "At four in the morning?" "Light's irrelevant down there anyway. I heard the sirens and — is it true someone's dead?" Quinn held up the evidence bag with the bone token. Eva went still. Not shocked. Still, the way a reader goes still at a familiar word. Her hand came up and stopped halfway. "May I—" She folded her hands in her lap instead. "It's a game piece." "I didn't say it was a piece of anything." "It looked carved. Like a die. A token." The hair went behind the ear again. "People leave strange things in stations." "Write your number down for the sergeant." Quinn watched her do it, watched the care she took, and let her go. Down on the platform, Hodge had the scenes-of-crime lot photographing the ring. He fell in beside her, lowered his voice. "Explorer, heart attack, guilty mate. Tell me where that theory fails." "It fails at the stairs." Quinn clicked the torch on and laid the beam flat along the platform dust. "Look. First response, down and back. And his. Brogue prints, size nine. They start here." The beam held on two clean heels, side by side, two yards from the bricked arch. "Nothing leads to them. Nothing leads away except twelve steps toward the ring, and then they stop. Nobody carried him — one man can't be carried without drag marks, and there are none. Nobody else walked this platform at all." "Dust can be brushed." "Then show me the brush strokes. Show me one." She straightened. "He didn't fall. He didn't wander in off the street, because the street door was locked from outside until we cut it, and your anonymous caller knew exactly where to send us. Fifty stalls came out of that hall tonight without touching a single stair we can prove, and they left him here with his money in his pocket and his name taken out of his wallet, on his back, hands folded, like something laid out for viewing." Hodge looked at the arch. The bricked-up dark behind the old tiles. "So where did he come from?" Quinn lifted the compass. The needle strained toward the brickwork, steady as a held breath. "That's what you're going to find me," she said. "The second door."
