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.

The third deadbolt was the loudest. It always was — a heavy iron clunk that Eva swore could be heard from the curry house downstairs — and Rory had only just thrown it back when she remembered she hadn't asked who was knocking. She pulled the door open on the chain first, the way Eva had drilled into her. Through the gap she saw charcoal wool, a flash of ivory, and one amber eye catching the weak hallway light. Her stomach dropped clean through the floorboards. "Lucien." "Aurora." His voice hadn't changed. It still curled around her name like it was something private, something he'd kept tucked in a pocket. "May I come in? Or shall we conduct this through a four-inch gap, which I confess has its own charm." She didn't move. Ptolemy wound figure-eights around her ankles, oblivious, purring at a man he'd never met. Traitor. "How did you find me?" "You're staying with the witch on Brick Lane. It wasn't a state secret." A pause. The other eye — the black one, the one that drank light rather than reflected it — flicked down the corridor, then back to her. "Though if it were meant to be, you might consider not having your deliveries from the Golden Empress addressed to this door. Yu-Fei's order slips are quite thorough." Of course. Of course he'd found the thread and pulled it. That was what he did. That was what he'd always done, right up until the night it had all come undone. Rory shut the door. For one petty, satisfying second she let him stand there on the wrong side of it. Then she slid the chain free and opened it properly, because pretending she could keep Lucien Moreau out of anything was a fiction neither of them had ever quite believed. He stepped inside the way he stepped into every room — as though it had been waiting for him. The cramped flat seemed to shrink around the cut of his suit. He took in the towers of Eva's books, the scrolls unrolled across the kitchen table and weighted at the corners with mugs, the research notes pinned three deep to the wall, and something almost like amusement softened the hard line of his mouth. "She's not changed, your friend. Still trying to read the entire library before the world ends." "Don't." Rory crossed her arms. "Don't do the charming thing. Not tonight." "I didn't come to be charming." "Then why did you come?" He set the tip of his cane against the floor and leaned on it, both gloved hands stacked over the ivory handle. Up close she could see the things the hallway light had hidden — a fresh nick along his jaw, the faint grey shadow of exhaustion under his eyes. Lucien did not get tired. Lucien did not bleed where people could see. The fact that he'd let her witness either felt deliberate, and that frightened her more than the knock had. "Because there are people asking after you," he said. "By a name you haven't used in some time." The room tilted. She heard herself say, very steadily, "Which name." "Malphora." Ptolemy stopped purring, as if even the cat understood. Rory turned and walked to the kitchen, mostly to put her back to him, to give her face a moment to remember how to be a face. She filled the kettle she didn't want, because her hands needed a task. "I told you that name in confidence." "And I have kept it in confidence. Three years, Aurora. I have not so much as whispered it." His voice came nearer; she heard the soft tap of the cane on the floorboards. "Which is rather the point. If I haven't spoken it, and you haven't, then someone else has learned it another way. And that should concern you a great deal more than I do." She set the kettle on its base without switching it on and gripped the edge of the counter. The crescent scar on her left wrist caught the kitchen light — pale and old, the one mark on her she'd never tried to hide. She felt him notice it. He always noticed everything. "You could have written," she said. "A letter. A note slipped under the door. You didn't have to come yourself." "No." "So why did you." The silence stretched long enough that she finally turned around. He was closer than she'd thought — close enough that she could smell cedar and cold night air and the faint metallic something that clung to him after he'd used the blade in the cane. His mismatched eyes held hers, and for once the practiced ease had gone out of his face entirely. What was left underneath was younger, and rawer, and unbearably difficult to look at. "Because the last time I let you walk away from me," he said quietly, "I told myself it was the professional thing. The kind thing. That you would be safer at a distance from what I am and what I do." His jaw tightened around the nick on it. "And I have spent three years discovering that I am a very good liar in four languages, and that I cannot lie to myself in any of them." Rory's heart was doing something complicated and unforgivable. "That's not fair." "No. It isn't." He didn't move closer; if anything he held himself rigid, as though stillness were the only honesty he had left to offer. "I'm not here to ask anything of you, Aurora. I'm here because someone knows your true name, and that means they can find you anywhere, and the thought of you alone above a curry house with three deadbolts and a cat between you and Avaros—" He stopped. Breathed. "I would not be able to live with myself. So. Here I am. Being unfair." The kettle ticked as it cooled. Downstairs, someone laughed in the curry house, a warm ordinary sound from a warm ordinary world that had nothing to do with realms or true names or half-demons standing in Eva's kitchen looking at her like that. "You hurt me," she said. It came out smaller than she meant it to. "When you sent me off with your good reasons and your charm. You knew exactly what you were doing, and you did it anyway." "I know." "You don't get to walk back in and—" "I know," he said again, and this time something cracked in it. "Tell me to leave and I'll go. I'll watch from the street, I'll keep them off you, and you'll never have to see my face. That much I can do whether you want it or not." His knuckles had gone white on the ivory handle. "But I find I cannot keep doing it from across the city and pretending it costs me nothing." Rory looked at him — at the tired eyes, the fresh cut, the cane, the careful, terrible stillness of a man bracing to be sent away. She thought of the night she'd left. How she'd waited, even then, for him to ask her to stay. How he hadn't. "You're an idiot," she said, and her voice shook. "A clever, fluent, beautifully dressed idiot." The corner of his mouth moved. "I've been called worse. In four languages." "Don't make jokes." She pressed the heel of her hand against her eyes, hard, and when she dropped it he hadn't moved an inch, hadn't dared. "Sit down. You're bleeding on Eva's floor and she'll have us both for it." A breath. "And then you're going to tell me everything you know. Slowly. From the beginning." Something eased in his shoulders — not relief, not quite, but the loosening of a held breath three years deep. "Yes," Lucien said. "From the beginning." Ptolemy hopped onto the chair Rory pulled out for him, settled, and began to purr again, as though he'd known all along how this would go.
