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.

Only include the prose of the scene without any markdown or commentary.

The knock came at half past eleven, three slow raps that carried up the stairwell over the thud of the bass from Silas' bar. Rory didn't need to look through the peephole. She knew the rhythm. She had lain awake in her bed a hundred nights, remembering it. She looked anyway. Lucien stood on the landing under the bare bulb, rain beaded on the shoulders of his charcoal suit. His platinum hair was slicked back, though a damp strand had escaped to curl against his temple. The ivory head of his cane rested in his gloved hand. Through the fish-eye distortion of the lens, one eye looked amber and the other looked like a hole cut into the night. She had once found that mismatch beautiful. She still did, which annoyed her. She unlocked the door but kept the chain on. "You're dripping on Silas' carpet," she said. "Silas' carpet has survived worse." His voice was low and dry, the vowels still Marseille beneath the polished English. "Hello, Aurora." "Rory. Nobody calls me Aurora except people who want something." "Then I am a man who wants something." His gaze moved past her shoulder, into the narrow hall, the kitchen light, the stack of Yu-Fei's takeaway menus on the radiator. It was a quick, clinical assessment, the way he might read a room before choosing which door to leave by. "May I come in? I would rather not have this conversation with the bulb buzzing over my head." "You had three months to have this conversation. You chose to send nothing. Not a message. Not a bloody postcard." Something flickered behind his eyes, too fast to name. "I know." "Do you?" "Yes." He shifted his weight, and the cane tapped once against the floorboards. "I am not here to argue about the past. I am here because someone is hunting the Ashworth ledger, and they have started with people who touched it. You touched it." Her stomach tightened. She had carried the ledger from the Ashworth safe house to a dead drop in Shoreditch, on his instruction, with no idea what was in it. She had handed it over and walked away and told herself that was the end of it. "That was your job," she said. "Not mine. I delivered a parcel. I deliver parcels for a living." "Yes. And you were very good at it." He said it quietly, and she hated how it landed. "Which is why they will come to you next, and why I would prefer you did not open the door to anyone else tonight." She let out a breath and slid the chain off. The door swung inward. She stepped back, arms folded, and he came in with the careful grace of a man who had learned to walk on a wounded leg and never let anyone see it. Water pooled on the boards around his polished shoes. He glanced at the sofa, the boxes of unpacked books, the mismatched mugs, the single framed photograph of her mother in a Cardiff classroom that she had not yet found the nerve to hang properly. He looked at everything except her. "You kept the mug," he said. She followed his gaze to the chipped blue mug on the counter. It was the one he had bought her from a market stall in Camden, the day she'd laughed so hard at his terrible attempt at a Welsh accent that she'd nearly choked on her tea. "It was the only mug without a crack," she said. "Liar." "Get out of my kitchen, Lucien." "It is not your kitchen. It is Silas' building, and he is in the pub below us, drinking like a man who has never heard of responsibility." He turned, finally, and she saw the lines of fatigue at the corners of his mismatched eyes. Whatever he had been doing these three months, it had not been restful. "Aurora. Rory. Please. Let me say this properly." She waited. Her pulse was loud in her ears, and she resented it. "I lied to you," he said. "Not about everything. But about the parts that mattered. I told myself that keeping you out of my world was a kindness. That you would be safer as a girl who delivered noodles and went home to her books and never once saw what I did at night." His jaw worked. "I was wrong. You had every right to walk away from me. You did it better than I deserved." Her throat ached. She had prepared a dozen cutting replies on the long bus rides home and in the bath and at three in the morning. None of them survived the sincerity in his voice. "You could have told me," she said. "Before. Not after I'd already decided you were a stranger who happened to know my bed." "I know." "Stop saying that." "Then tell me what you want me to say, and I will say it." She laughed, a short, unhappy sound. "That's the problem, isn't it? You always know what people want to hear." "Not you." He took one step toward her, and the cane stayed silent for once. "I never knew what you wanted. That was what I loved about you. You surprised me." The bass from downstairs thumped through the floor. Somewhere a siren rose and faded past Brick Lane. Rory looked at the chipped blue mug, then at the man in the wet charcoal suit who had broken her heart on purpose and then, too late, tried to explain why. "You're still dripping on the carpet," she said, and her voice wavered in a way she couldn't quite hide. "Take off your coat before you catch your death. Then you can tell me everything. Every word. And then you can leave." He almost smiled. "Only if you let me stay until the rain stops." She did not answer. She went to the kitchen to put the kettle on, and she did not look back to see whether he followed.
