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 by the time Quinn ducked under the blue-and-white tape, but the cobbles of the alley behind St. Pancras still held it, slick and mirrored under the halogen floods. Someone had run a cable from a generator on the pavement, and the whole crooked passage glowed like an operating theatre. The smell came first. Copper, yes, but also something floral and rotten underneath, like lilies left too long in a vase. "Took your time, Guv." DC Ashworth peeled off his latex gloves and offered her a cup of service-station coffee that she refused with a shake of her head. He was twenty-nine, eager, still wearing the cheap suit his mother had bought him for the academy. "Talk me through it." "Male, forty to fifty. No ID yet. Cleaner from the hotel found him at five-twelve this morning when he came out to empty the bins." Ashworth gestured with his chin toward the body, which lay on its back in the centre of the alley, arms flung wide, palms up, as though it had fallen from a great height and been caught mid-surrender. "Single stab wound, left side, below the ribs. Forensics reckon a long, thin blade. Stiletto, maybe." Quinn crouched. Her knees complained. She set her torch down on the cobbles and let the beam play across the dead man's face. Mid-forties. Clean-shaven. A small nick under the jaw where he'd cut himself that morning with a safety razor, and the shave was fresh, which meant he'd dressed expecting to be seen. The suit was Savile Row or close to it. His shoes had been polished within the last day. His fingernails were clean. "Time of death?" "Between one and three. Doctor's being cagey." "He always is." She pressed two fingers to the dead man's lapel, then to the cobbles beside him. "Cobbles are wet." "It rained till four." "And under him?" Ashworth paused. "Sorry, Guv?" "Under him. Did anyone look?" He glanced at the two uniforms by the tape, who pretended suddenly to be very interested in their notebooks. Quinn slid a gloved hand beneath the dead man's shoulder, lifted a fraction, and shone the torch into the gap. Dry. Bone dry. A pale oval of cobble the colour of old teeth, ringed by damp like a tide mark. "He wasn't killed here," Ashworth said, quick to recover. "Dumped after the rain stopped. That fits with the blood, actually. Not enough of it. Stab like that, you'd expect a pool." "Mm." Quinn lowered the shoulder, rose, and walked the circumference of the body in a slow arc. The blood there was — she stopped. "Ashworth. Come here." He came. "What do you see?" "Blood, Guv. Pooled at the wound site. About two hundred mils, Forensics reckon." "And its shape?" He frowned down at it. "Irregular." "Irregular how?" "It's just. A puddle." She squatted again and traced the air above the stain with the tip of her torch. The blood had settled in a rough oval, yes, but the oval was not centred on the wound. It sat perhaps six inches to the dead man's left, and its edge against the cobbles was not ragged, the way spilled blood should be where it crept into the mortar. It was clean. A curve as precise as if someone had drawn it with a compass. "Blood doesn't pool like that," she said. "Not on a surface like this. It should have found the grout lines. Run into the low points." She nodded at the shallow gully where the cobbles dipped toward the drain. "And it should have gone there. Gravity works, Ashworth, even on Tuesdays." "Maybe it clotted before —" "It didn't clot. Look at the sheen." He looked. The surface of the blood caught the halogen and threw it back wet, glossy, as though it had been poured a minute ago. Quinn's jaw worked. She pulled a pen from her inside pocket and, before Ashworth could object, lowered the tip toward the edge of the stain. The pen stopped an eighth of an inch above the blood. Not resting on it. Stopped. As though the air there had thickened. She drew the pen back. Lowered it again. Same result. "Guv —" "Quiet." She stood. Her eyes swept the alley with the patience that eighteen years had taught her, and she began to catalogue the wrongnesses she had been refusing to see. The lilies-and-rot smell, which no one else seemed to notice. The way the halogen light bent, just slightly, around the dead man's outstretched left hand, so that his fingers cast two shadows instead of one, and the second shadow was longer than it should have been. The single bootprint on the wet cobble three feet from the body, which pointed away from the corpse rather than toward it, and which was not a print she recognised from any standard-issue boot she'd ever seen — the tread was a spiral. A spiral. She felt the old cold thing slide under her ribs, the thing that had lived there since Morris. It had the same flavour now as it had in that warehouse in Deptford three years ago, when she had come around the corner and found only his radio on the floor, still warbling, and a smell of lilies. "Guv, you all right?" "How long have you been here, Ashworth?" "Since four-forty." "And it's been raining till when?" "Four. Give or take." "And the body was found at five-twelve." "Yeah." "So the cleaner came out at five-twelve and saw a man freshly murdered, in an alley where it had been pouring rain until four, and the cobbles under his body are dry." Ashworth opened his mouth. Closed it. "Who called it in?" "Cleaner. Name's —" he flicked through his notebook — "Ahmed Osman. Hotel's got his details." "Get him back. I want to speak to him myself. And Ashworth." "Guv?" "Don't touch the blood. Don't let anyone touch the blood. Cordon tighter. Send the uniforms to the end of the alley." He hesitated. "Forensics are on their way." "Tell them to wait." He went. Quinn stayed where she was, in the hot white pool of the lights, and looked down at the dead man whose blood would not sit the way blood sat, and at the second shadow of his left hand, which moved, very slightly, against the cobbles, though nothing in the alley had moved at all. She took out her phone and scrolled to a number she had not called in eleven months. *Evie,* she typed. *Need a word. Off the record. Now.*
