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.

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 third deadbolt gave with a heavy clunk, and Rory pulled the door open on the last person she had expected to see on Eva's landing at half past eleven at night. Lucien Moreau stood under the bare bulb with both hands folded over the ivory handle of his cane, as if he had come to read her a will. The charcoal suit was immaculate. The platinum hair was slicked back without a strand out of place. Only his face gave him away. He looked like a man who had rehearsed a speech on the stairs and lost it somewhere between the second floor and the third. "Aurora," he said. Not Rory. Not Laila, the name she had worn for him like a borrowed coat. Her whole name, carefully, like something that might break. "How did you find this place?" She kept one hand on the door and her weight on the balls of her feet. From the flat below came the rattle of a wok and the sweet, scorched smell of cumin and onions. Brick Lane never really went to sleep. "I am a broker of information, *chérie*. It would be embarrassing if I could not find a woman who has been hiding in her friend's flat for three weeks." "I'm not hiding. I'm cat-sitting." Something moved behind her ankles. Ptolemy, Eva's fat tabby, slid out through the gap and sat down on the landing to regard Lucien with total contempt. Lucien looked down at him. The amber eye caught the light and glowed, and the black one swallowed it. "He does not like me," Lucien observed. "He doesn't like anyone. It's why I trust him." The corner of Lucien's mouth twitched. It was almost a smile, and it hurt to see, because she had spent a month cataloguing his smiles and this was one of the small honest ones, the kind he gave when he thought no one was watching. She hated that she still knew the difference. "May I come in?" "No." "Rory." There it was. He had kept the word back until it counted, and it landed exactly as he must have known it would. She looked at the floor. She looked at the cat. She looked at the stripe of light from the flat spilling across his polished shoes. "Five minutes," she said. "And you leave the cane by the door." "You do not trust me." "I trust the blade in it even less." He inclined his head, conceding, and stepped over the threshold. The flat closed around him the way it closed around everyone: too small, too warm, too full. Books climbed the walls in leaning towers. Scrolls stood in an umbrella stand and lay across the radiator. Eva's research notes papered every flat surface in her cramped, furious handwriting, and the kitchen table had vanished under a drift of index cards. Lucien turned in a slow half circle, taking it in with the expression of a man visiting a foreign country he had heard about but never believed in. Rory shut the door and threw the deadbolts one after another. Clunk, clunk, clunk. Each one sounded louder than it should have. When she turned around he was watching her hands. "Three locks," he said quietly. "It's Eva's flat. She's paranoid." "And you?" "I'm just careful." She leaned against the door and folded her arms. Her left thumb found the small crescent scar on her wrist and pressed it, an old habit, the way some people touch a pocket to check for their keys. Lucien's gaze followed the movement. He had once traced that scar with a fingertip, in a room with rain on the windows, and asked how she had got it. She had told him the truth, a swing set and a rusted bolt and being seven years old. It was the first true thing she had told anyone in London. She let her hand drop. He set the cane against the wall beside the coat hooks, gently, the way you would set down a sleeping animal. Without it he seemed both smaller and more dangerous. She had forgotten he stood a little crooked when he wasn't performing, weight on the left, as though some old injury still complained. "You look tired," she said before she could stop herself. "You look well." His eyes moved over her and stopped at her hair, which she had hacked shorter at the sink last week and regretted since. "You cut it." "Don't." "I am only saying it suits you." "You don't get to say things like that." It came out sharper than she meant, and the room went very still. Downstairs the wok clattered on. Ptolemy slid back through the door gap and jumped onto a stack of Sumerian grammars, where he began to wash a paw. "You don't get to turn up at midnight with your good manners and your good suit and tell me my hair suits me. Not after the way it ended." "No," Lucien said. "I do not." She waited for the rest of it, for the clever turn, the elegant deflection. He was so good at those. Instead he stood in the middle of Eva's crowded floor with his hands open at his sides and let the silence stretch until it became his answer. "I lied to you," he said at last. "By leaving out the part that mattered. I have told myself since that night that it was to protect you, and some of that was true. But mostly I was afraid that if you knew what my father's people wanted from me, you would look at me the way you are looking at me now." "How am I looking at you?" "As though you are trying to decide whether I am a monster." She made herself hold his eyes, the amber one and the black. "I wasn't deciding that," she said. "I decided that the first day. I don't care what your father is." She swallowed. "I cared that you let me walk into that warehouse thinking I knew where the exits were." "Yes." "You let me *trust* you." "Yes." His voice cracked on the word, a hairline fracture in all that polish. "And I have not stopped being sorry for it. That is not why I came, but I did not want to stand here and pretend it was not in the room." Rory pushed off the door. She hadn't decided to move, but she was suddenly close enough to smell him: sandalwood, cold rain, a trace of the cigarettes he swore he'd given up. The smell hit her under the ribs. Three weeks of careful, sensible distance, gone in one breath. "Then why did you come?" His throat moved. "Because someone has been asking questions about you. A man with a Cardiff accent, who says he is an old friend, who knows the name Carter and the name Ellis and the name of a certain café in Cathays." He watched her face as the blood left it. "I thought you would want to know. I thought you would rather hear it from me than from him." *Evan.* The floor seemed to tilt. She put out a hand for the table and found instead the front of Lucien's jacket, fine wool, warm, and his hand closed over hers at once. Not tight. Just there, steady, an anchor. "Breathe," he murmured. "Rory. I have you." "You don't," she whispered, but she did not let go. "Then let me try to." She should have stepped back. Every sensible part of her, the cool-headed part that had walked out of one bad man's house and onto a train and into a new life, said to step back now. But his thumb had found the pulse at her wrist, right beside the scar, and he was not moving it. He simply held it, as though he was counting her heartbeat and wanted her to know he was listening. "This doesn't fix anything," she said. Her voice shook. "I know." "I'm still angry." "You should be." "I missed you." It fell out of her like a dropped plate, and she wished immediately she could catch it. "God. I hate that I missed you." Lucien closed his eyes. When he opened them, the amber had gone bright and wet. "*Moi aussi*," he said, so softly she almost lost it under the noise from the street. "Every day, and I hated it too." Neither of them moved. His forehead came down to rest lightly against hers, a question rather than a claim, and she felt his breath shudder out. Behind them Ptolemy knocked a scroll off the radiator with a soft thump, and neither of them so much as flinched. "Stay tonight," she heard herself say. "On the sofa. Only because someone's looking for me and you're apparently the one who knows about it." "Only because of that," he agreed gravely. "And because it's late." "And because it is late." Her hand was still in his. Neither of them let go.
