You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

The third deadbolt stuck the way it always stuck, and Rory had to jiggle it with her thumb while balancing a mug of tea gone cold in her other hand. Below the floorboards the curry house exhaled heat and cumin and fried onion straight up through the vents, and Ptolemy the tabby wound himself hard around her ankles, complaining about the knocking. She wasn't expecting anyone. Eva was in Oxford until Thursday chasing down some footnote about grave goods, which left Rory on cat duty in the cramped one-bedroom above Brick Lane, surrounded by Eva's drifts of books and scrolls and research notes in three different inks. She had kicked a path through them in her socks. She had told exactly one person where she would be. The door swung inward and the stairwell breath hit her first, damp plaster and rain, and then him. Lucien Moreau stood on the landing with water beaded on the shoulders of his charcoal suit, his slicked-back platinum hair darkened at the edges, one hand resting on the ivory head of his cane. He looked wrong without the low light of Silas's bar behind him. Taller than she remembered, though she knew precisely that he had four inches on her five foot six. Tired in a way tailoring could not hide. Rory's fingers tightened on the mug. "No." "Bonsoir to you too." His mouth tipped, but it didn't reach his eyes, and those were impossible not to stare at up close. One amber, one black. In the bar she had been able to pretend it was a trick of the lamps. On the landing, with the bare bulb buzzing, there was no pretending. "May I come in before your neighbor decides to be interested?" Behind her, Ptolemy hissed. Three weeks. Three weeks since he had put his drink down untouched on the scarred wood at Silas's, since he had looked at her the way he was looking at her now and said, I can't be the man you call when you're in trouble, Rory, and walked out with that even tap of his cane on the floorboards. Three weeks since she had told herself good, fine, she had left Cardiff and Pre-Law and Brendan Carter's disappointed silences and Evan's hands to stop needing men who decided what they could be for her. She didn't move. "How did you find me?" "Eva told me." At her expression he lifted his free hand. "She told me yesterday, before she left. She worries. She said if anything went sideways I should check the flat with the cat and the three locks." "Nothing's sideways." His gaze dropped to her left wrist where her sleeve had ridden up, to the small crescent-shaped scar there, white as milk. A childhood accident on a garden wall in Cardiff, and he knew the story because she had told it to him stupidly at one in the morning over fried rice containers from the Golden Empress, because his accent had thickened when he laughed and she had wanted to keep making him laugh. His eyes lingered half a second too long and her skin burned under it. "Rory." Rain ticked on the skylight in the hall. Somewhere downstairs a pan clattered and someone shouted in Bengali. His suit was dark with rain at the knees, and there was a split in the leather of his shoe she had never seen before. Lucien Moreau did not scuff his shoes. "Please. Five minutes." She hated that her first thought, under the anger, was how good he smelled, wet wool and lime and something warmer, like struck matches. She stepped back because if she didn't she was going to say something she couldn't take back in a hallway. He ducked under the lintel and the flat shrank around him. The sitting room was barely wide enough for Eva's sagging armchair and the low table buried under stacked monographs. Scrolls tied with red ribbon teetered on the windowsill. A tower of photocopies leaned against the kettle. Lucien picked his way through it with his cane, careful not to disturb the piles, and that care did something stupid to her chest. Ptolemy streaked under the armchair and glared out with huge green eyes. "You can put the kettle on if you're going to hover," Rory said, and shut the door and threw all three deadbolts because her hands needed the work. The clicks sounded obscenely loud. "I don't want tea." "What do you want, Lucien?" He turned. In the cramped room, with the curry smell rising and the rain hammering the window over the fire escape, he looked cornered. She had seen him smooth-talking a doorman in rapid Italian, had seen him switch to soft, precise Mandarin for Yu-Fei when he came to collect for the restaurant, had heard him murmur in French to the bartender when he thought she wasn't listening. He used language like his cane, elegant and concealing a blade. Now he cleared his throat and said nothing for a moment. "Evan was in Silas's last night," he said. The name landed like a dropped plate. Rory set the mug down too hard on top of a gazetteer and tea slopped over her knuckles. She wiped it on her jeans. Cool-headed, Eva always teased, our Rory with the ice water in her veins, the girl who talked a Cardiff landlord out of keeping her deposit with case law quoted from memory. Her heart banged against her ribs. "He doesn't know where I live," she said. "I live above the bar now. Silas wouldn't—" "Silas didn't tell him. I was there." Lucien's jaw worked. "He was asking. Offering money for a delivery girl's route. Your route." The flat tilted. She thought of her scooter chained behind the Golden Empress, the insulated box strapped to the back, the late drops down unlit mews where she counted house numbers out loud to keep herself company. She thought of Evan's voice going soft the way it did before it went hard. She crossed her arms to stop herself from rubbing at the scar. "And you told me to stop calling you when I'm in trouble," she said. Her voice came out steady, which satisfied some barrister's daughter part of her even as her eyes stung. "So why are you here? To watch?" His amber eye flashed. "Don't." "Don't what?" "Make me into him." He said it quietly, in French first, ne me confonds pas avec lui, and then in English, as if he couldn't trust her to understand him when it mattered. "I left that night because you asked me to find out who sold your new address to your ex, and the answer was a man I owe money to in Marseille. A man whose father knew my father. You understand? My father is not a kind story from Avaros. If I pulled that thread, it would lead straight to you." She stared at him. The rain ran down the window in crooked veins. Ptolemy crept out and butted his head against Lucien's polished, ruined shoe, and Lucien, the impeccable fixer who charged two hundred pounds just to answer a question, bent without thinking and offered two fingers for the cat to sniff. "I told you to stay away to keep the thread from pulling," he said to the cat, to the floor, to anywhere but her. "Not because I didn't—" He stopped. The unsaid thing sat between them, fat as a book. She remembered the night before that last night, his hand on the back of her neck in the alley behind Silas's while the bins stank and the music thumped through brick, his mouth hovering over hers as he asked in a whisper if she wanted this. She had said yes. She had fisted her hands in those perfect lapels and kissed him until her knees gave. He had tasted like bitters and lime. He had walked her to her door and never touched her again except to leave. "You didn't what?" She hated how breathless it sounded. He looked up at her then, really looked, and her straight black hair was sticking to her damp forehead and her socks didn't match and there were tea stains on her T-shirt and he looked at her like she was the only legible thing in a room full of paper. "I didn't want to be another man who made you smaller to keep you safe," he said. Something cracked clean down the middle of her. Three weeks of telling herself he was cold, he was mercenary, he brokered information and nothing else, and here he was dripping on Eva's rug with his cane and his ruined shoes, having come up three flights in the rain because her ex was asking questions. Attraction was the easy part. Attraction was the way his suit pulled across his shoulders when he straightened, the paleness of his hair against his sun-browned skin, the precise, almost tender way he righted a sliding scroll with the tip of his cane. The hard part was this sudden, furious tenderness rising in her throat like nausea. "You don't get to decide that alone," she said. She stepped over a pile of notes and the floorboard creaked. Curry and rain and cat and him. She was close enough now to see the stubble along his jaw, the faint scar through his left eyebrow she had never asked about. "You don't get to walk away and call it noble, Luc. I left a man who told me what was best for me. I left Wales for that. I'm not doing it in London in a nicer suit." "I know." His voice was rough. He lifted his hand and stopped it in midair beside her cheek, asking. Always asking. That was the difference, and her whole body leaned toward the heat of his palm before her brain caught up. "I know. I'm asking now. Let me stay until the rain stops. Let me call in two favors and get Evan barred from every pub on this side of the river. Let me—" She put her hand over his and pressed his palm to her face. His skin was cold from the street. Her scarred wrist rested against his cuff, crescent white against white shirt, and his thumb brushed over it like a vow. "Stay," she said. "Not just until the rain stops." Outside the window the city hissed. Inside, Ptolemy flopped dramatically onto Lucien's foot and began to purr, and Lucien laughed, surprised and real, and the sound undid the last knot in her stomach. She took his cane and leaned it against the armchair where he could reach it in a second, blade and all, because she knew him, because she chose to know him. When he pulled her in, careful of the books and the cat and everything fragile, his kiss tasted of rain and apology and something beginning again.
