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.

# UNANNOUNCED The knock came at half past nine on a Thursday night when Rory was in her oldest jumper with a cup of tea that had gone cold an hour ago, sitting cross-legged on Eva's sofa while her friend reorganized a stack of grimoires for the third time that week. "I'll get it," Eva said, abandoning her books with obvious relief. She padded across the cluttered flat, and Ptolemy lifted his tabby head from his perch on an armchair, ears pricked with interest. Rory heard the chain rattle as Eva looked through the peephole. A pause. A sharp intake of breath. "Oh, bloody hell," Eva muttered. The deadbolts came undone—all three of them, which meant Eva was either terrified or furious. Possibly both. Rory set down her tea and unfolded from the sofa, her pulse already quickening in that involuntary way it did whenever trouble walked through a door. And Lucien Moreau was always trouble, even if he was the kind of trouble that made her stomach flip. He stepped into the flat like he owned it, the way he stepped into every room. Charcoal suit impeccable despite whatever he'd been doing before this—the suit was always impeccable. Rain pearled on his platinum blond hair, and he carried that ivory-handled cane like it was part of his spine. One amber eye and one black eye swept across the cramped space, cataloguing everything with that unsettling precision of his, before landing on Rory with the weight of something heavy and sharp. Twelve weeks. That's how long it had been since she'd seen him. "Ms. Carter," he said, and his voice was soft in that way that meant he was dangerous. The Marseille accent wrapped around her name like smoke. "I didn't expect to find you here. Though, in retrospect, I should have." Eva's face had gone tight. "He showed up at Silas' bar asking questions. I told him to—" "To find me, yes, I'm aware," Rory cut in, still on her feet, still trying to regulate her breathing like it was nothing. Like her hands weren't remembering the texture of his suit jacket. "What do you want, Lucien?" "Charming as ever." He leaned his weight on the cane, not because he needed it—she'd never quite believed he needed it—but because it gave him something to do with his hands. A tell. She'd learned his tells. "A greeting might be traditional. Perhaps an inquiry into my wellbeing after three months of silence." "Twelve weeks," she said. "And you're the one who walked away." "*I* walked away?" His heterochromatic eyes narrowed. The black one seemed deeper in the lamplight, like an actual void. "Curious interpretation of events." Eva made a small noise of distress and moved toward the kitchen. "Tea. I'm making tea. I'll be in the other room if you need me, which you won't, because you'll both be civilized, yes? Yes. Good." She disappeared, leaving Rory alone with the worst decision she'd ever let herself make, currently standing in Eva's living room dripping rainwater on a stack of first editions. "There's no chair," Lucien observed, glancing around at the cluttered flat. "I suppose we stand, then." "You shouldn't be here." "And yet." He tilted his head, that gesture that made him look like something that had learned human mannerisms from a distance. "I'm standing in your friend's flat, soaking her books, waiting for an explanation. Your explanation, preferably. For why you turned off your phone, stopped responding to messages, and vanished like you'd never agreed to—" "I agreed to nothing," Rory said, but it came out shakier than she wanted. She wrapped her arms around herself. "We ended it, Lucien. You said—you said this was a mistake." "I said no such thing." "You said we were complicated." "We *are* complicated." He shifted his weight, and the cane tapped once against the wooden floor. Ptolemy, undisturbed, continued grooming his paw. "That is not a reason to vanish. That's a reason to *talk* about it." Rory turned toward the window, toward the rainy East London street below, where streetlights smeared orange across the wet pavement. From here, she could see the curry house downstairs lit up warm and gold, could see the blurred figures moving past the steamed windows. Normal people. Normal lives. She'd been trying to have one of those. "You were the one who stopped calling," she said quietly. There was a silence. Long enough that she could hear Eva clattering about in the kitchen with unnecessary aggression, could hear the rain against the window, could hear her own heartbeat in her ears. "Three weeks," Lucien said finally. "Three weeks I gave you space because you asked for it. Because I thought you needed time to process what happened with Evan, to feel safe again without... without complication. Without me. And then I showed up at your flat and got some surly musician who didn't know who I was, and I realized you'd left. You'd simply packed things and gone." She did look at him then, turning sharply enough that her hair swung. His face was calm, but she knew how to read the micro-expressions now—the tightness at the corner of his mouth, the way his jaw worked slightly as if chewing on words he wasn't saying. "I needed space from you specifically," she said, and it was cruel but honest. "Not from... from what happened. But yes, from you. You're intense, Lucien. You're dangerous, and mysterious, and you have secrets that probably have bodies under them—" "Several," he agreed pleasantly. "—and I had just gotten away from someone who controlled me. I couldn't go from Evan's hands straight to... to whatever this is. I needed to remember who I was when I was alone." He absorbed this quietly, then moved—with that unsettling grace of his—to the bookshelf. His cane clicked softly against the floor with each step. He studied the spines of Eva's collection, his heterochromatic gaze catching on titles written in languages Rory couldn't read. "Did you?" he asked finally. "Remember who you were?" The question was so simple that she almost didn't answer it. She almost turned away, suggested he leave, told him she'd moved on. But there was something about Lucien that had always made lying difficult. The half-demon could smell them on her like blood. "Yes," she said. "And then I realized I didn't like her very much. And I realized I'd been using the space as an excuse not to deal with being terrified of you." He turned then, and the streetlight from the window caught the golden eye, made it shine like something precious. "Of me?" "Of this. Of wanting something and having it be... real. Of being with someone and not knowing if I'm making another mistake. Of being—" She stopped, jaw tight. "Of being loved?" he finished quietly. The words hung in the cramped, book-filled space between them. Ptolemy yawned. Outside, London rained on, indifferent and grey. Lucien set his cane against the bookshelf with deliberate care. When he moved toward her, he moved slowly, giving her time to flee, to object, to protect herself. She didn't. "I'm not Evan," he said, stopping close enough that she could smell him—expensive cologne and something else, something like storm clouds and silver. "I won't demand your obedience. I won't dim your brightness. What I will do is show up uninvited at your friend's flat when you disappear. What I will do is speak four languages just so I can curse properly when you're gone. What I will do is stand in the rain like a fool because the alternative is not knowing if you're safe." Rory's breath had gone shallow. "That's not love, that's obsession." "Perhaps they're the same thing when one is half-demon." He reached out, and his fingers found her wrist—the one with the crescent scar, the one that remembered old hurts. His thumb traced it gently. "I've been patient, *mon coeur*. I can be patient still. But I won't pretend you don't matter. I won't pretend I don't." She should have said something clever. Something that protected herself. Instead, she said, "I'm scared." His expression softened in a way she'd rarely seen, vulnerable as a opening door. "So am I."
