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 had stopped an hour before Quinn got the call, but the cobbles in the alley behind St Dunstan's still held the water in their grooves like black veins. She ducked under the tape and pulled her coat tighter. The uniforms parted for her without a word. They'd learned. "Morning, Quinn." DI Callum Breece crouched beside the body, a paper cup of station coffee balanced on a brick. "Hope you had your Weetabix." "What've we got?" "Male, mid-thirties. No ID on him. Throat's the main event." Breece gestured with two gloved fingers. "SOCO reckon a blade, maybe six inches. Single draw, left to right. Open and shut, near enough. Mugging gone wrong." Quinn didn't answer. She stepped past him and let her eyes travel the alley end to end before she looked at the body at all. The dead man lay on his back in the mouth of a brick recess that had once held a coal chute. His left arm was flung above his head; his right rested neatly at his side. The coat was a good wool, dark, still buttoned. His shoes were polished. No wallet, no watch, no phone, which fit Breece's theory. The throat was, as advertised, a ruin. She crouched. Her knee clicked. She ignored it. "Time of death?" "Doc says three, four hours. Before the rain stopped." "Before." She looked at the cobbles under the body. Dry. Not quite dry — slightly damp, as any stone in London was always slightly damp — but not running-wet like the alley around him. She moved her gaze outward in slow, careful rings. The water had pooled around him in a perfect lip, as though something had held it back while it fell. "Who found him?" "Bin man. Six-twelve this morning. Called it in straightaway. Cleanest witness you'll ever get. He's in the van with a blanket if you want him." "In a minute." Quinn lowered her face nearer the wound. The cut was clean, yes. Left to right, yes. But there was no arterial spray. A throat opened that deep should have painted the wall behind him up to his shoulder-height, a long fan of it, and there was nothing. A smear on his collar. A rind of dark on the cobbles beneath his neck. That was all. She looked at Breece. "Where's the blood?" "He bled out. It's under him." "Not enough." "He's a small fella." "He's six foot if he's an inch." She straightened. "And he's on his back, Cal. You cut a man's throat standing, he goes forward. You cut it from behind with him on his knees, he pitches face-down. He doesn't lay himself out like a brass on an undertaker's table." Breece sipped his coffee. "So someone arranged him after." "Why?" "Because they're a nutter. It's London." She took out her torch and clicked it on, though the morning was already bright enough. She wanted the angle of the beam. She walked a slow arc around the body, sweeping the cobbles, the brick, the mouth of the recess. There. At the edge of the dry patch — the lip where the rain had refused to come — a line in the damp. Not scuff, not drag. A line drawn in something finer than chalk and paler than salt, already half-washed but not quite gone. She bent. It followed the curve of the dry place and closed on itself. A circle. Broken at one compass point by the shape of the body itself, as if whoever drew it had used him as the southern arc. "Cal. Come look at this." He came over, knees cracking. "What?" "Tell me what you see." "Wet bricks." "Look at the edge. There." He squinted. "Scuff." "It's drawn." "Drawn with what?" She ran her gloved finger along it, and held it up to him. A film of something pale clung to the nitrile. It wasn't salt. It had the wrong weight. It felt, when she rubbed her thumb across it, faintly greasy, like ground bone mixed with tallow. Breece's face did the thing his face always did when he didn't like an answer. It went blank. "Alright," he said. "So your mugger's a weirdo. He drew a circle." "The rain stopped at five. You said he died before the rain stopped." "Yeah." "Then how is the ground under him dry?" Breece opened his mouth. Closed it. Opened it again. "Water pooled here." Quinn nodded at the shallow puddle three feet away. "And here. And ran down the camber there. It didn't go round this spot because of his body, Cal. It went round because of the line." "That's mental." "Look at the cut again." She pointed. "Left to right. A right-handed attacker facing him. But he's been moved onto his back after. And there's no spray on the bricks." She turned slowly, torch lifted. "No spray anywhere. No cast-off on the walls, no boot-prints tracking out of the scene. The bin man came in from the south. Our killer didn't leave." "They had to leave. They're not here." "They didn't leave by the alley." Breece laughed, but it came out thin. "What, they flew?" She crouched a third time and lifted the edge of the dead man's coat with her pen. The lining was sodden — but not with rainwater. Darker than that. Heavier. Soaked through from the inside of the coat, as if his blood had not sprayed outward but had been drawn downward, into him, through him, somewhere else. "Quinn." "I see it." "Quinn, what am I looking at." She didn't answer for a long moment. She was counting the points where the pale line touched the cobbles. Five. Evenly spaced. One of them had been scuffed out by a SOCO boot, but the spacing told her where it had been. The watch on her left wrist felt suddenly heavier. She was aware of it the way she'd been aware of her pulse in the weeks after Morris. Three years. Three years of cases that almost made sense, of files with gaps she could put a finger through. "Cal," she said, standing. "Who took the photographs?" "Yates." "Get them back up here. I want the whole alley shot again before anyone touches anything else. And clear the uniforms off the dry patch. I don't want another boot on that circle." "Quinn, come on. It's a mugging." "It isn't a mugging." She turned her torch off and slid it into her coat pocket. Her voice was flat. "A mugger takes a wallet. They don't take the blood." Breece stared at her. The coffee in his hand had gone cold.
