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 knock came after ten. Rory counted it without meaning to — three sharp raps against the door of Eva's flat, too crisp to be Eva, who knocked like she was trying to break the wood, and too late to be anyone with good intentions. The smell of cumin and fried onions from the curry house below had been seeping through the floorboards all evening, thick enough to cling to her sweater, and Ptolemy had been asleep on top of a stack of Eva's research notes, his tabby tail twitching every time a page shifted in the draft. She had been sitting cross-legged on the floor trying to translate a marginal note Eva had left in terrible Latin, her back against the overstuffed couch that took up too much of the cramped one-bedroom. At the sound she went still. Another three raps. Patient. Precise. She pushed herself up, straight black hair falling forward over her shoulders, and padded to the front door in her socks. Eva's place always felt like a library that had exploded — books double-stacked on the shelves, scrolls unfurled across the kitchen counter and held down with chipped mugs, loose paper covering every surface. Navigating it required sideways steps. "Who is it?" she called. A beat. Then a voice she had not heard in four months, low and accented, familiar enough to tighten her throat. "Rory." Her hand stopped an inch from the first deadbolt. She hadn't expected to hear that particular nickname in that particular voice again. Lucien had always said it like it belonged to him, the r rolled just slightly, an affectation she used to pretend she didn't like. She stared at the door — at the three deadbolts Eva insisted on, all locked, just as Eva had left them when she'd gone to stay with her sister for the week — and felt her pulse start to thud too hard against her ribs. She had been cool-headed when she left him standing in the alley behind Silas' bar. She'd been cool-headed when she hadn't answered his messages. She was not feeling particularly cool-headed now. She threw the first bolt. Then the second. The third stuck the way it always did and she had to jiggle it, the small crescent-shaped scar on her left wrist catching the dim hall light as she twisted her hand. She opened the door. He was exactly as impeccable as she remembered, which was irritating. Rain had darkened the shoulders of his tailored charcoal suit but hadn't managed to make him look disheveled. His platinum blond hair was still slicked back, not a strand out of place, water beading on it. In his right hand he held the ivory-handled cane, the one that concealed a thin blade, though he didn't lean on it so much as pose with it. He was watching her, and even in the poor light of the stairwell his eyes were startling — one amber, warm and human, the other flat black, demon-dark, both fixed on her face. For a second neither of them spoke. The hallway smelled like rain and hot oil. "You moved," he said at last, in English. His gaze flicked past her, over the crowded flat, and came back. "Eva's flat. I went to Silas' first." "You're observant," she said. Her voice came out steadier than she felt. "You also know how to use a phone." "So do you. You chose not to." That landed. Rory tightened her grip on the door, her bright blue eyes narrowing. She was five foot six and he was nearly five eleven, and the stairwell made him seem taller. He'd always used his height like a tool, not looming but inclining, closing distance just enough to make her aware of it. "What do you want, Lucien?" He exhaled, and she saw then that he was holding himself too straight, his left hand tucked slightly against his side under his jacket. Not a pose. A guard. "To come inside before I bleed on Eva's welcome mat," he said lightly, but his French accent sharpened at the edges when he was in pain. "If you can spare the hospitality." Her eyes dropped. A dark line was seeping through the charcoal wool at his ribs, almost invisible until he shifted and the wet fabric caught the light. Rory stared at it, her quick, out-of-the-box brain already sorting possibilities — dumpster behind the curry house, no, the cut was too clean, blade work — while another, more unruly part of her was already stepping back and pulling the door wider. "Christ," she muttered. "Get in." He moved past her with a soft tap of the cane against the threshold, bringing rain and the faint smell of cologne and copper into the cramped flat. Ptolemy lifted his head from the notes, stared at the intruder with flat judgment, then resettled. Rory shut the door and threw all three deadbolts again on instinct, fingers working fast. When she turned, Lucien hadn't gone far. He was taking in the flat with a fixer's inventory glance — the books, the scrolls, the tower of takeaway containers from Golden Empress that she'd meant to return to Yu-Fei — but he stopped when he saw the delivery bag slumped by the couch, the red and gold logo smeared. "You are still running for Yu-Fei," he said. "I work part-time," she said, defensive before she could help it. "It pays rent. Above Silas' bar isn't free, even when Silas likes you." "I know." He said it quietly. "I know where you live, Rory. I know you left Cardiff and Pre-Law and Brendan and Jennifer Carter's very good expectations. I know you left Evan." Her name for her ex in his mouth made her jaw lock. Evan. The reason she'd fled Cardiff at Eva's behest two years ago, the reason she still checked the locks twice. Lucien knew better than to say it like that, as if he had a right to the history. "Don't," she said. Lucien inclined his head, conceding. He swayed slightly and caught himself on the cane, knuckles whitening around the ivory handle. "You're hurt," she said, and the anger drained as fast as it had come. She was already moving, clearing a space on Eva's kitchen counter, shoving aside a scroll that cracked as it rolled. "Sit. Or — don't sit on Eva's books, she'll kill both of us. Sit here." He obeyed, perching against the counter, and with a grimace he unbuttoned his suit jacket one-handed. Underneath his white shirt was cut open along the side, stuck to him with blood. It was not deep, she thought, but it was long, a slash. Rory grabbed the first-aid kit Eva kept wedged between herbal guides — Eva, bless her, prepared for demon scrapes — and a clean tea towel. She had to step close to see, close enough that she could see the rain still in his hair and the faint line of stubble along his jaw he hadn't bothered to shave. "Who did this?" she asked, dabbing. Her hands were steady. She prided herself on that, on being cool-headed when it counted. "A client who decided he did not want to pay in money," Lucien said through his teeth, but he didn't pull away. His heterochromatic eyes dropped to her face. "It is not serious." "It is if you show up at my — at Eva's door at ten at night to get it looked at," she said. She pressed the towel firmer and he hissed, amber eye flaring. "You have other people. You know half the supernatural underworld. You speak four languages, you could have asked for help in any of them." "I did not want other people," he said. The words hung in the hot, curry-scented air between them. Ptolemy jumped down and wove between Rory's ankles, purring. Rory's hands faltered. She remembered the last time they'd been this close — his apartment near Spitalfields, her coat still on because she had intended to leave, his hand hovering at her waist like he wasn't sure he was allowed to touch her. She had kissed him then, because she was tired of being afraid, and he had kissed her back like he'd been waiting. And then she'd panicked. Because it was too soon after Evan, because Lucien was half-demon and knew too many dangerous people, because a girl who'd fled Pre-Law and Cardiff to deliver noodles in London didn't get to want something that complicated. She'd left before morning and told him not to call it anything. He had listened, in his own way. He had given her space until now. "You left," she said suddenly, very quietly. "That night. You let me just walk out." His mouth twitched. "You told me to, Laila." That name — the one he'd called her only once, half-teasing, half-wondering — made her look up. Her black hair brushed his chin. "I was waiting for you to tell me not to," she admitted, and the honesty scraped. "And then you didn't call." "You told me quick thinking was your strength, not mine," he said, and there was humor there, pained. "I thought — I thought you needed time. That your Barrister father did not raise a daughter who lets a half-demon from Avaros make decisions for her. So I waited." "You waited four months and then you bled on Eva's floor?" "It seemed dramatic enough to get your attention." Despite herself, a startled laugh escaped her. She shook her head, pressing the towel again, her left wrist turning so the little crescent scar showed white against her skin. His gaze caught on it, as it always did. He reached with his free hand, hesitated, then brushed the scar with his thumb, barely touching. His fingers were cold. "Rory," he murmured, and this time it wasn't just a name. It was a question, in French-accented English, soft enough that she could pretend she hadn't heard it if she wanted to. She didn't pretend. She leaned in, just an inch. The towel was still pressed to his side, her other hand braced on the counter beside his hip, caging him without meaning to. The cramped flat seemed to shrink until it was only the circle of light over the counter, the rain against the windows above Brick Lane, the cat's tail flicking. "Lucien," she said, matching his tone. "If I let you stay the night, because you can't walk back to Silas' bar like this —" "Yes?" "— you have to actually stay. No disappearing. No brooding fix-it act where you vanish for my own good." His black eye seemed to swallow the light. The amber one never left hers. "I can stay," he said. "If you want me." She looked at the blood on the towel, at the ridiculous, expensive suit ruined for her, at the man who had learned to knock in threes because Eva had three deadbolts and he remembered. Rory swallowed, her heart hammering loud enough she was sure he could hear it. "I want you to stay," she said. He let out a breath she hadn't realized he'd been holding, and his cold hand came up to cup the back of her neck, careful, asking. She tipped forward the last distance, and his mouth met hers, tasting like rain. Behind them, Ptolemy knocked a stack of research notes to the floor with a thump, and neither of them pulled away.
