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.

Two people who parted on complicated terms are forced together again when one shows up unannounced at the other's flat. There's history between them — attraction, hurt, and things left unsaid. Write the scene from the moment the door opens. Use the codex entries above as your world reference for characters and setting. Only include the prose of the scene without any markdown or commentary.

The first deadbolt slid back with a clack. The second took two tries, because her hands were not quite steady, and by the time she reached the third she had already decided not to look through the spyhole. She knew who it was. Nobody else in London knocked with that particular patience, three measured raps spaced like a metronome, as if the door owed him an answer. Rory pulled the door open. Lucien Moreau stood on the landing under the bare bulb, one gloved hand resting on the ivory head of his cane. The charcoal suit was immaculate, cut close across the shoulders, and his platinum hair was slicked back as if he had walked through a storm without acknowledging it. Amber eye, black eye. They regarded her with the same unhurried attention they always had, the way a man studies a chessboard he has already won. "Aurora," he said. Nobody called her that anymore except her mother, and her mother did it with a sigh attached. Lucien said it like a word in a language he was fond of. "You can't just turn up here," she said. "I did not turn up. I arrived." He tilted his head toward the stairwell. "There is a great deal of noise coming from the curry house downstairs, and I could not hear myself think. Might I come in?" "No." "Ah." He nodded slowly, as though she had given a reasonable answer to a question he had not expected her to answer at all. "That is what I expected. Which is why I did not ask permission." He stepped past her before she could block the doorway, and the scent of him reached her, cedar and rain and something faintly metallic underneath, like a coin held too long in the palm. Behind her, Ptolemy the tabby abandoned his post on the bookshelf, dropped onto a stack of Eva's research notes with a thud, and fixed Lucien with the suspicious glare of a creature who had been waiting for a reason to dislike him. "Traitor," Rory muttered to the cat. "He is clearly the only sensible one in the flat." Lucien set his cane against the nearest unburdened surface, which was the arm of the sofa, and surveyed the room. Books stood in towers. Scrolls leaned in corners like drunk sentries. Paper covered the coffee table, the kitchen counter, the windowsill. "Still living in a library, I see. Eva has not changed." "Eva's in Lisbon for three weeks. I'm minding the place. And the cat." She shut the door and, out of habit now, slid all three bolts home. The sound was louder in the small room than it should have been. "Why are you here, Lucien?" He turned to face her. The lamplight caught the amber eye and made it glow like a struck match. "Because you have been avoiding my calls for nine weeks," he said, "and because the people who came to your bar on Tuesday were not looking for a pint." Her stomach tightened. "Silas told me about the men in the back booth. I didn't think—" "No. You did not think. That is rather the problem with you, Aurora. You think very quickly, and then you act before you have finished thinking about the consequences." His voice softened, which was worse than when it was sharp. "I have spent nine weeks making certain those men do not come back. I would like to be thanked. Or shouted at. Either would be preferable to the silence." She folded her arms, aware of the thin white crescent on her left wrist, the old scar she always caught herself touching when she was nervous. She made herself drop her hand. "You left," she said. "After Marseille, you didn't say a word. You just went. I woke up and your side of the bed was cold, and you'd left me a note that said *Don't go back to the bar alone*. That was it. That was everything you had to say." "I know what I wrote." "Then you know it wasn't enough." For a long moment neither of them spoke. Somewhere below, the curry house extractor fan groaned to life. Lucien's jaw moved, very slightly, as though he were choosing among a dozen answers and rejecting each in turn. "It was the only thing I could safely say," he said at last. "Men like me do not make promises we cannot keep. I have a father in Avaros who would like nothing better than to see me on my knees, and a great many people who would be glad to use you to get to me. Staying would have made you a target. Leaving was the kinder choice, even if it did not feel kind to you." "You don't get to decide what's kind for me." "No," he agreed quietly. "I do not. I have been learning that rather slowly." She should have told him to leave. She had the words ready, sharp and clean. Instead she heard herself say, "Did you eat?" His mouth twitched, almost a smile. "That is not the question I expected from you." "Well, you look terrible. Your hair's wet, and you've got that grey look you get when you've been running on coffee and spite." She crossed to the kitchen, filled the kettle, and kept her back to him. "There's soup in the fridge. Yu-Fei sent a container home with me on Monday, and I'm not allowed to let it go to waste." Behind her, she heard the faint tap of the cane being lifted, then the soft footsteps of a man who had not walked into a room without knowing exactly where to stand. He stopped at the counter, close enough that she could feel the heat of him at her back. "Aurora," he said, and this time there was no lightness at all in it. "I am sorry." She closed her eyes. The kettle began to hum. "I know," she said. "That's the worst part."
