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 always stuck. Rory had wrestled with it for the better part of two weeks, ever since Eva had left her the keys and fled to Edinburgh on some errand she refused to explain, and tonight it gave way only after she'd thrown her shoulder into the door and muttered a curse her mother would have despaired of. Ptolemy wound between her ankles, complaining, and she nudged him back with one socked foot as she yanked the door open— —expecting the curry-house delivery boy with her dinner, or perhaps the downstairs landlord come to grumble about the smell of incense. Instead, Lucien Moreau stood on the landing. For a moment, neither of them spoke. The stairwell's single bulb threw half his face into gold and left the other in shadow, so that his mismatched eyes—one amber, one black as a drowned well—seemed to belong to two different men. He was dressed as he always was, charcoal suit pressed to a knife's edge, the ivory handle of his cane resting loosely in one gloved hand. He looked, infuriatingly, as though he had simply stepped out of a photograph she'd been trying not to keep. "Hello, Aurora," he said. The full name. He was the only one who ever used it, drawing the syllables out like he was tasting them, and she hated how the sound of it still landed somewhere beneath her ribs. "No," she said, and started to close the door. His cane came up—not threatening, just a soft tap against the wood, halting it. "Three seconds. That's all I'm asking." "You asked for three seconds the last time. In Marseille. I gave you three seconds and you used them to disappear." Something flickered across his face. To anyone else it would have looked like nothing, a momentary stillness, but she had spent four months learning to read the small weather of his expressions, and she knew it for what it was. A wince. "That's fair," he said quietly. "I know it's fair. I was there." Ptolemy chose that moment to slip past her ankles and out onto the landing, where he promptly began rubbing his head against the toe of Lucien's immaculate Italian shoe. Traitor, she thought. Lucien glanced down at the cat with the faint, pained patience of a man who did not wish to be charmed and was being charmed anyway. "May I come in?" he asked. "It isn't safe to talk on the stair. And before you tell me you don't care whether I'm safe—it isn't safe for you either." That, more than anything, was what made her step back. She told herself it was practical. She told herself it had nothing to do with the way the light caught the platinum of his hair, or the low rasp of his voice, or the particular cologne he wore—something with smoke and orange peel underneath—that came drifting through the doorway and dragged a whole season of her life back up out of the dark. She told herself a great many things, and none of them were true, and she stood aside anyway and let the Frenchman into Eva's flat. He had to turn sideways to fit between the towers of books. Eva's research had colonized every flat surface—scrolls unrolled and pinned with mugs, notebooks splayed open, a half-translated codex propped against the kettle. Lucien moved through it with the careful precision of a man crossing a minefield, set his cane against the arm of the sofa, and turned to face her in the cramped square of space that passed for a sitting room. "You're hard to find," he said. "That was rather the point." "Eva covers her tracks well. Better than most. It took me—" He stopped himself. "It took time." "How much time?" He didn't answer. But she saw it in him, the answer he wasn't giving: too long. Long enough that finding her had cost him something. Lucien Moreau did not spend without expecting return. Rory crossed her arms and leaned against the kitchen counter, putting the width of the room between them, such as it was. "You didn't track me across an entire city to apologize, Luc. You don't do apologies. So whatever this is, say it and go." "I came to warn you." He said it simply, without flourish, and that scared her more than any threat would have. "Someone is asking after a woman matching your description in the lower markets. Asking by the wrong name." The wrong name. Her stomach dropped a slow inch. "Which name." "Malphora." The word sat in the air between them, heavy as a struck bell. She felt the blood leave her face and hoped, foolishly, that he hadn't seen it. He had. He always saw. "You told me that name meant nothing," he said, very gently. "In Marseille. When I asked. You looked me in the eye and told me you'd never heard it." "I lied." "Yes." A breath. "I rather thought you might have." The silence stretched. Ptolemy hopped onto the sofa and curled against the leg of Lucien's trousers, and Lucien, absurdly, did not move to shift him, only stood very still with the cat against his shin and his strange eyes fixed on her face. "Is that why you left?" she asked, before she could stop herself. The question had lived in her for months, a splinter under the skin, and now it came out raw and graceless. "Because you figured it out? Because you realized what I was, and decided I wasn't worth the—" "No." The word cracked out of him, sharp enough that even the cat lifted its head. He took a step toward her, then visibly checked himself, one hand tightening on the back of the sofa. When he spoke again his voice had dropped, gone rough at the edges. "I left because I knew what was coming for you. And I knew that if I stayed near you, I would lead it straight to your door. So I went somewhere loud and visible and made myself easy to follow, and I let them chase me halfway across the continent instead of you." He exhaled. "It worked, for a while. It isn't working anymore." She stared at him. The room felt suddenly too small, the heat of the radiator and the weight of all those unsaid things pressing in. "You could have told me," she whispered. "You'd have insisted on coming with me. And you would have died." His jaw worked. "I have done a great many things I'm not proud of, Aurora. Leaving you on that quay, with you looking at me like—like that—" He stopped, and for the first time in all the time she'd known him, Lucien Moreau seemed unable to find the next word in any of his four languages. "It is the only one I regret." She didn't trust herself to speak. The crescent scar on her wrist throbbed, the way it always did when her pulse went high. She pressed her thumb against it, an old habit, and saw him track the movement, saw something in him soften and break. "Don't," she managed. "Don't come here and be honest with me now. It's not fair. You don't get to be honest now." "I know." He picked up his cane. For one terrible second she thought he meant to leave again, and her whole body went tight with the wanting and the dreading of it. But he only leaned on it, and stayed. "Tell me to go, and I'll go. I'll set a watch on this place from a distance and you'll never see me. That's the safe thing. That's what I should offer you." "And if I don't tell you to go?" His mouth curved, that crooked half-smile she'd dreamed about and despised herself for dreaming. "Then I expect we're both going to be very stupid about this. Again." Outside, somewhere down on Brick Lane, a car alarm wailed and went silent. Ptolemy purred against his leg. And Rory, who was cool-headed and clever and known among her friends for never doing the reckless thing, looked at the half-demon standing among her cousin's books with his heart held out like a knife reversed, and found that she did not, after all, tell him to go.
