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 three deadbolts came undone one at a time, each with its own particular complaint, and Rory had the door half-open before she registered who stood on the other side. Lucien Moreau filled the narrow landing as though it had been built around him, one gloved hand resting on the ivory head of his cane, the charcoal of his suit drinking up what little light bled from the stairwell bulb. Rain had darkened his shoulders. A single strand of platinum hair had come loose from its slick discipline and curved against his temple, and for a moment that was all she could look at — that one undisciplined thing about a man who allowed himself nothing of the kind. "Aurora," he said. She didn't open the door any wider. "How did you find me here." "You answered to your own name without thinking. That's careless." His mismatched eyes moved past her, into the flat — over the tide of books and the unspooled scrolls, the lamp throwing yellow over Eva's chaos. "Though I suppose that's rather the point of a friend's flat. No one looks for a woman in a place that belongs to someone else." "That's not an answer." "No," he agreed. "It isn't." Ptolemy chose that moment to wind himself around her ankles, a warm tabby pressure, and she nearly stumbled. Lucien's hand twitched on the cane — an old instinct, to catch her — and stilled. She saw him decide not to. That, more than anything, told her the four months between them had been as long for him as they had for her. "You shouldn't be here," she said. "I'm aware." "I asked you not to come looking." "You did." He inclined his head, a small bow that managed to be both apology and refusal of one. "And I respected it for precisely as long as it was safe to. Things have changed, Aurora. May I come in, or would you prefer to have this conversation where the entire of Brick Lane can enjoy it?" She should have said no. There were a great many reasons to say no, and most of them lived in the memory of a rooftop in Southwark and the things he'd said there — and the things he hadn't, which had been worse. But the rain was steady behind him and his jaw was set in that way she'd learned meant he was carrying something he didn't want to put down in the open, and Rory had never in her life been good at closing a door on a problem. She stepped back. He came in the way he did everything, without hurry and without wasted motion, easing the door shut behind him and turning the topmost deadbolt with a click that felt absurdly intimate in the small room. He set his cane against the bookshelf. He did not take off his gloves. "Tea," she said, because she needed to do something with her hands and there was a kettle. "Or whatever passes for it in Eva's cupboards." "I didn't come for tea." "I know why you came." She filled the kettle anyway, her back to him, watching his reflection ghost across the dark window above the sink. "You came because something's gone wrong and you need me to be useful again." The silence behind her had a texture. She heard him move — the soft displacement of a man crossing a room he'd already mapped — and when he spoke he was closer than she'd braced for. "That's not why I came." "Lucien." "I told myself it was," he said quietly. "Right up until you opened the door. I had a very efficient speech. Information, a name, a debt I thought you'd want to collect. Transactional. The way you prefer things now, since me." A beat. "But you opened the door, and you'd done something to your hair, and I forgot the whole of it." She set the kettle down without turning it on. The crescent scar on her left wrist caught the lamplight as she gripped the counter edge; she felt his gaze land on it, the way it always had, that small flaw he'd once traced with his thumb as though it were the most interesting thing in London. "Don't," she said. "You asked me not to look for you," he went on, relentless and soft, "and I want you to understand that I didn't. Four months, Aurora. I let you have your silence because I owed you that. Because the last thing I did was let you walk off that roof believing I'd chosen the job over you, and I had no right to follow a woman I'd just proven I'd sell out." She turned around. She hadn't meant to. "You did sell me out." "I bought you time," he said, and there it was — the flare of something under the polish, amber eye and black, both of them burning. "There's a difference, and you'd see it if you weren't so determined to make me the villain of a story you'd already decided on. I gave them a Malphora that wasn't you. I sent them three days in the wrong direction. The price was that you had to hate me for it, and I let you, because hating me would keep you moving and grief would not." The flat was very quiet. Outside, a bus hissed through the wet street, throwing brief light up the walls and across the spines of Eva's books. "You let me think," Rory said, and her voice came out smaller than she wanted, "that I'd been a fool. That I'd trusted a man who didn't—" She stopped. Started again. "I cried in a Tesco car park, Lucien. Over you. Do you have any idea how undignified that is." Something crossed his face that she'd never seen on it — not the practiced sympathy he wore for clients, not the smooth amusement, but something raw and unhandsome and entirely his. He took a step closer. She didn't step back, and noticing that she didn't seemed to undo him a little. "I should have told you the truth," he said. "I have a great talent for protecting people in ways that look exactly like betrayal. It's the one inheritance from my father I've never managed to sell." His gloved hand rose, hovered near her face, and stopped. "May I?" "That's a terrible idea." "Yes." "We part badly. It's what we do." "Then we'll part badly again," he murmured, "after. I've come a long way to be hated properly, Aurora. The least you can do is let me earn it." And against every cool-headed, out-of-the-box, sensible thing she had ever prided herself on, Rory found her hand closing over his wrist — over the smooth leather, over the steady pulse beneath it — and she did not pull it away.
