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 was always the one that stuck. Rory had to put her shoulder into the door, jiggling the brass knob the way Eva had taught her, before it finally surrendered with a complaint of metal. She expected the postman, or Eva returning early with bags of takeaway, or — worst case — a Jehovah's Witness immune to the curry-shop smell that clung to the stairwell. She did not expect Lucien Moreau. He stood on the landing as though he'd been poured there, all sharp lines and stillness, his charcoal suit immaculate despite the rain misting the window behind him. The ivory handle of his cane rested loosely in one gloved hand. The other he kept tucked into his coat pocket, the very picture of a man who had nowhere else to be and all the time in the world to not be there. His mismatched eyes found hers. The amber one caught the weak hallway light. The black one gave nothing back, as always. "Rory," he said. Just that. Her name in his mouth, soft on the vowels, the way no one else said it. She kept one hand on the door. Ptolemy wound between her ankles, oblivious, purring at the stranger as if he were a friend. Traitor. "How did you find this place?" Her voice came out steadier than she felt, which she counted as a small victory. "Eva keeps it off every map there is." "She does." A faint curve at the corner of his mouth. "It took me eleven days. That is, I should say, a record. Your friend is very thorough." "Then she didn't want you here. Which makes two of us." She started to swing the door closed. The tip of the cane caught it. Not hard — he didn't shove, didn't force. He simply set the ivory against the wood and held it, and the gentleness of it was somehow worse than violence. She could have pushed past it. She knew she could. She didn't. "Five minutes," he said. "If you still want me gone after five minutes, I'll go. I'll walk back to whatever hole you think I crawled out of and you won't see me again." "That's what you said in Marseille." The words were out before she could stop them, and she hated how raw they sounded. She watched something move behind his face — a flinch, quickly smoothed, the kind of tell she'd learned to read across a hundred shared rooms and three months of running and one terrible morning when she'd woken alone with a note and an address and no Lucien. "I know what I said," he answered quietly. The rain hissed against the glass. Down in the curry house, someone dropped a pan, and the clatter rose up through the floorboards like applause for a joke nobody had told. Rory's heart was doing something stupid and arrhythmic, and she despised it for that, for betraying her after she'd spent four months teaching it to behave. She stepped back and let the door open. He came in slowly, taking in the flat the way he took in everything — cataloguing it, valuing it. The towers of books on every surface. The scrolls bound with twine. Eva's research notes pinned to the walls in her cramped, furious hand. He set his cane against the bookshelf with deliberate care, and Rory found she was watching his hands, the long clever fingers, and made herself stop. "You're living with the witch," he said. "I'm staying with my friend." She folded her arms. "Four minutes." A breath of a laugh. He turned to face her, and in the small space of the room there was suddenly nowhere safe to look. The last time they'd been this close he'd had his thumb against her jaw and his forehead against hers and he'd told her, in that low and ruined voice, that she had to leave before sunrise. That he wasn't what she thought. That she'd be safer anywhere he wasn't. "I made a mistake," he said now. "You made a decision." She lifted her chin. "There's a difference. A mistake is something you trip into. You sat down and planned mine out to the minute. You bought the train ticket. You wrote the note." She heard her voice fray and pressed on through it. "Don't dress it up as an accident, Lucien. At least give me the dignity of having been left on purpose." He was silent for a moment. Then: "I thought I was protecting you." "From you." "From everything that wants what I am." He took a step closer, and she could smell him now — cedar and cold air and something faintly sulphurous underneath, the half of him that wasn't human at all. "There are things in this city, Rory, that would have used you to reach me. Cut you open to see what I'd do. I have enemies who do not stop at doors. Three deadbolts." His gaze flicked toward the entry. "Three. Did you choose those, or did she?" "Don't." She shook her head. "Don't make this noble. You don't get to walk out and call it love." "I never called it anything." His eyes held hers, and for once neither half of him gave him cover. "That was the cowardice. I let you go without telling you what it was, because if I'd said it I wouldn't have been able to do it." The room went very quiet. Even Ptolemy had stilled, curled now on a stack of grimoires, watching them both with golden unconcern. Rory's throat ached. She thought of all the nights in this borrowed flat, the crescent scar on her wrist pressed to her mouth as she lay awake, the way she'd taught herself to be furious because fury was easier to carry than the other thing. "And what was it," she said, barely above a whisper. "Since you're so brave now. Since you found the door." He didn't answer at once. He reached out instead — slow, asking — and turned her wrist over with two fingers, baring the small pale crescent there. He'd traced it once, in the dark, and asked how she'd got it, and she'd told him a true thing she'd never told anyone. "It was the only honest thing I'd done in years," he said, "loving you. Which is why I had to ruin it." "Lucien—" "I'm not asking you to forgive it." His thumb moved over the scar, once, and then he let go as though it cost him. "I came because something is hunting you that has nothing to do with me, and you should know it. And because eleven days of looking for this door taught me I'd rather be standing on the wrong side of it than safely far away. That's all. That's the truth, finally, and it's too late, and I know it." Outside, the rain came down harder. Rory looked at the open door, and then at him, and did not move to either.
