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 knocking started during the part of the night when nothing good ever knocked. Rory had fallen asleep on Eva's sofa with a book open on her chest — something about the pre-Christian burial customs of the Welsh Marches, which Eva had insisted was relevant and Rory had insisted was a cure for insomnia. Both of them had been proved right. Ptolemy was a warm weight against her hip. Eva was in Bristol until Thursday. Three knocks. Not urgent. Measured, almost polite, the rhythm of someone who had all night and no intention of leaving. Rory got up. The book slid to the floor and Ptolemy fled under the coffee table with a sound of great offence. She undid the first deadbolt, then the second, then remembered she had no reason to trust whatever was on the other side and stopped with her hand on the third. "Who is it?" A pause. Then, muffled through two inches of council-issue door: "You are going to make me say it in the corridor." She knew the voice before he finished the sentence. She knew it the way you know a song from its first quarter-second, the way your body knows the top of the stairs in the dark. Her hand stayed where it was on the deadbolt. "Yes," she said. "I think I am." "It's Lucien." "Lucien who?" "Aurora." She turned the bolt. She told herself it was because the hallway light on Brick Lane had a habit of attracting things worse than Frenchmen, and because if she left him out there he would still be there in the morning, immaculate and infuriating, and Mrs. Kaur from the curry house downstairs would have questions. The door opened. He filled the frame the way he always had — not with size, he wasn't a large man, but with a kind of density, as though the air around him had been compressed to a higher standard. Charcoal suit. Waistcoat. The ivory handle of his cane cupped in his right palm. Platinum hair slicked back so neatly it looked painted on. And the eyes: one amber, catching the bad hallway bulb and turning it into something warm; one black, giving nothing back at all. There was a split lip. That was new. A thin dark line at the left corner of his mouth, dried, deliberately unattended. "You look terrible," she said. "I look extraordinary. I have simply had an evening." He glanced past her into the flat. "May I?" "No." "Ah." He didn't move. "Then may I stand here and bleed on the doormat, which I am told belongs to your friend and is embroidered with a Latin curse?" "It's a blessing." "It is not a blessing. I read Latin." He tilted his head, and for one unguarded second the amber eye did something soft, and she hated him for it. "Rory." Nobody else said her name like that. Two syllables he'd never quite anglicised, the r trilled slightly at the front of the mouth, like the name was something he was tasting rather than saying. She stepped back from the door. He came in and took the flat in one long sweep — the towers of books, the pinned map of the Thames with red thread crossing it eleven times, the scroll weighted flat with a mug of cold tea. His mouth twitched. "Your friend has an interior designer, I see. His name is Chaos." "Sit down before you fall down." "I do not fall down." He sat down. On the arm of the sofa, because of course he wouldn't sink into the cushions like a normal person, and he laid the cane across his knees with the exactness of a man setting a table. Rory stayed standing. She was aware of her T-shirt, which had a hole at the collar, and her bare feet, and her hair flattened on one side from the sofa cushion. She was aware of these things because he was not looking at them, and Lucien Moreau not looking at something was the loudest thing he did. "Four months," she said. "Nineteen weeks." "You counted." "I am precise. It is my only virtue and I overuse it." He touched his lip with the pad of his thumb, checked it, found nothing. "You did not call." "You told me not to." "I told you it would be safer not to." "Right, yes." She folded her arms. "Sorry. I must have missed the part where those were different sentences." Something moved in his face. Not much — with him it was never much — but she'd spent long enough learning the dialect. A tightening at the outer corner of the black eye. A stillness settling over him like a coat being buttoned. "They were different sentences," he said quietly. "I have thought about very little else." "That's convenient. You've had nineteen weeks." "Yes." He let that sit there. He didn't defend it. That was the unbearable thing about him — he never argued when you were right, he just absorbed it, and left you standing there holding your own anger like something you'd shoplifted and now couldn't put back. Rory went to the kitchen alcove because it was somewhere else to be. She filled the kettle. The pipes clanked in the wall the way they always did, and Ptolemy came out from under the table to investigate the visitor, and Lucien — she watched from the corner of her eye — lowered one gloveless hand and let the cat headbutt his knuckles. "Why now?" she said, over the rising noise of the kettle. "Because someone is asking about you by name." The kettle roared. She kept her back to him. "Which name?" "That is the interesting question." He shifted; she heard the cane click against the floorboards. "Not Carter. Not Rory. Not the delivery girl from the Golden Empress, though God knows enough of the city has your bicycle memorised." She turned around. "Say it." "Malphora." The kettle clicked off. In the sudden quiet she could hear the traffic on Brick Lane, a siren somewhere north, the small mechanical purr of the cat. "That's not a real name," she said. "It is a very old real name, and someone spent a great deal of money tonight trying to buy it from me, and when I declined they became—" he indicated his lip with two fingers, unhurried — "conversational." "You didn't tell them." "Rory." He said it almost gently. "I have made my living for eleven years by knowing precisely what a piece of information is worth, and I have never once been wrong about the price." The amber eye came up. "I was wrong tonight. I underpriced you. I could have had a house in the sixth arrondissement." Her throat did something inconvenient. "Don't," she said. "Don't what?" "Don't be — decent. Not now. Four months of nothing and then you come in here with a split lip and *I chose you* and I'm supposed to—" She stopped. Her hands were shaking. She pressed them flat on the counter. "You left me on a bridge, Lucien. You put me in a cab and you said it was for my safety and you didn't look back, and I watched you not look back the whole way down Southwark Street." "I know." "You don't get to know. You get to explain." He stood. He crossed the tiny room and he didn't touch her, and that was somehow worse; he stopped a foot away and the space between them hummed like a struck wire. "Because if I had looked back," he said, "I would not have got in the other cab. And you would be dead now, and I would be a man who had loved someone very badly for a very short time." His mouth twisted, not quite a smile. "I am half a demon, Aurora. I am not half a fool. I only wish the two were more clearly divided." She looked up at him. The bad kitchen light made a ruin of his beautiful face and she wanted, absurdly, to put her thumb against the split in his lip. "Nineteen weeks," she said. "Nineteen weeks." He exhaled. "I am not asking to be forgiven. I am asking to sit in this appalling room and drink whatever your friend calls tea and tell you everything I know, and then you may throw me back into the corridor and the Latin doormat will have its revenge." Rory took down two mugs. Her hands had stopped shaking, mostly. "It's a blessing," she said. "The doormat." "It is absolutely not." "Sit down, Lucien." He sat.
