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 told Eva a dozen times to get it fixed, and Eva had told her a dozen times that a sticky lock was a feature, not a flaw — anyone trying to break in would lose their patience before they lost their nerve. So when the knock came at half past eleven, soft but insistent, Rory found herself fighting the brass for a good ten seconds before the door swung open, and by then she'd already worked herself into an irritation that had nowhere to land. It landed on Lucien Moreau anyway. He stood in the dim stairwell light with his weight tipped onto the ivory-handled cane, one shoulder against the doorframe like he'd been poured there. The charcoal suit was immaculate, of course. It was always immaculate. Even now, well past midnight, not a thread of the platinum hair out of place, not a crease where a crease shouldn't be. The amber eye caught the bare bulb overhead and glinted; the black one gave her nothing at all. "Rory," he said, and the way he said it — the way her name softened on a French tongue — made her stomach do something she resented. "No." She started to close the door. His cane caught it. Not violently. Just a polite, immovable interruption, the brass ferrule wedged against the jamb. "Three minutes." "You don't get three minutes. You don't get three seconds. You don't get to stand there looking like a Savile Row advert at midnight after—" She stopped. Ptolemy had wound himself around her ankles, the traitor, purring up at Lucien like he'd brought tuna. "How did you even find me here? This is Eva's flat." "Which is precisely why I assumed you'd be here." A faint smile. "You always go where someone else's name is on the lease. It makes you feel invisible." That landed too close. She hated that he knew that. She hated that he'd noticed. "Three minutes," he said again, gentler now, and the black eye did something she couldn't read, and against every instinct she'd spent six weeks sharpening, Rory stepped back and let him in. The flat swallowed him whole. It always astonished her how small Eva's place felt the moment another person entered — the books stacked in leaning towers on every surface, the scrolls in their cardboard tubes, the research notes pinned and taped and weighted under chipped mugs. Lucien navigated it with the careful economy of a man who'd learned long ago not to disturb other people's chaos. He didn't sit. He stood in the narrow channel between the sofa and the coffee table and turned to face her, both hands folded over the head of the cane. "You left," he said. "Astute." "In the middle of the night. Without a word." "I left a word." She crossed her arms. "I left several. They were on the mirror, in lipstick. I believe one of them was *don't*." Something flickered across his face — there and gone, like the shadow of a bird across water. He had a beautiful face and he knew it and he used it the way other men used money, but the thing about Lucien, the dangerous thing, was that every so often the mask slipped and you saw the man underneath flinch. She'd built an entire foolish hope on those flinches once. She wasn't doing that again. "I deserved that," he said. "You deserve a great deal more than that." "I know." He set the cane against the arm of the sofa and that small surrender — a man like Lucien giving up the thing that doubled as a weapon — made her go still. "I came to tell you something, and I am going to do it badly, because I have spent six weeks composing it and every version is a lie I'm too tired to perform." Rory said nothing. The radiator ticked. Somewhere below them the curry house was closing down, the clatter of shutters, a man laughing in Bengali. "When I told you to walk away," Lucien said, "in the alley behind Silas' — when I said you were a liability, that I worked alone, that whatever you imagined between us was a fiction—" His jaw tightened. "There was a contract on you. Carrow had put a price on the woman who'd been seen with me, and the surest way to make that price worthless was to make it true that you meant nothing to me. So I made it true. Loudly. In front of the people who needed to hear it." She felt the floor shift very slightly beneath her, the way it did on the Tube when the train started before you'd braced. "You're saying you lied to protect me." "I'm saying I'm a coward who found a convenient excuse to do something I would have done anyway." He looked at her steadily, both eyes now, amber and black. "I am very good at lying, Rory. It's the only thing I've ever been better at than caring about people. So when both were on the table, I chose the thing I'm good at. That is the entire shape of me. I thought you should know it before you decided whether to slam the door." "I already opened the door." "You can still slam it. Doors are forgiving that way." She laughed — one short, helpless sound that surprised them both. It cracked something open in the room. He took half a step toward her, careful, asking, and she didn't step back, and that not-stepping-back felt like the most reckless thing she'd done in years. "Carrow's dead," she said. Her voice had gone rough. "Lucien. The contract's gone. So whatever you're doing here at midnight, you don't have a convenient excuse anymore. There's no one to perform for." "I'm aware." He was close now, close enough that she could smell cedar and something darker underneath it, the faint sulfur-trace that all his kind carried no matter how good the cologne. "That's why I came tonight and not last week. I wanted to be standing here with nothing to hide behind." He glanced at the cane, abandoned by the sofa, and then back at her, and his mouth tipped into something that wasn't quite a smile. "You'll notice I'm doing rather badly." "You're doing terribly," she agreed, and reached up, and the crescent scar on her wrist caught the lamplight as she pressed her palm flat against the lapel of that perfect, ruinous suit. She could feel his heart underneath it, going far too fast for a man who pretended he had none. "Three minutes," she said. "You said three minutes. You've got about forty seconds left." "Then I'd better not waste them on words." "No," Rory said. "You'd better not."
