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 three deadbolts gave way one after another, a slow percussion that Rory had learned to read like a heartbeat. She'd half-expected Eva, back early with takeaway and apologies. She'd braced for the landlord, or a courier, or the curry-house owner downstairs come to complain about Ptolemy yowling through the floorboards at three in the morning. She had not braced for Lucien Moreau. He stood in the dim of the stairwell with the streetlight behind him, and for one disorienting second the platinum of his hair caught the glow so that he seemed lit from within—some pale, expensive ghost in a charcoal suit. The ivory-handled cane rested loosely in his right hand, more affectation than necessity, though she knew better than most that it was neither. "Rory," he said. One amber eye, one black, both fixed on her with that unhurried attention she'd spent four months trying to forget. "You look like you've seen something terrible." "I have." She didn't move from the doorway. Behind her, Ptolemy threaded a figure-eight around her ankles, supremely indifferent to the tension thickening the air. "You're supposed to be in Marseille." "I was. Marseille is tedious in the winter." He tilted his head, and the streetlight slid off the sharp planes of his face. "Aren't you going to invite me in? I'm told it's poor form to leave a guest standing in a stairwell that smells so aggressively of vindaloo." "You're not a guest. Guests are expected." Her grip tightened on the edge of the door. The third deadbolt was still warm under her palm where she'd thumbed it open. "How did you even find this place? Eva moves like she's being hunted." "Eva *is* being hunted, in a manner of speaking. So are you." A pause, deliberate, the kind he laid down like a card he wanted her to look at. "Which is precisely why I'm here. May I?" She should have shut the door. There was a clean, simple satisfaction in the image of it—the wood swinging closed an inch from that perfect, infuriating face, the bolts sliding home one, two, three, the whole night sealed away on the other side. She'd rehearsed versions of this for months, lying awake in the flat above Silas' bar, composing the cold things she'd say if she ever saw him again. She stepped back and let him in. He moved past her with the unbothered grace of a man entering a room he'd already mapped, and the scent of him followed—cedar and something darker underneath, smoke and warm metal. He took in the chaos of Eva's flat in a single sweep: the books stacked into precarious towers, the scrolls unspooled across the kitchen table, the research notes pinned in overlapping layers to every inch of wall. He didn't comment. He simply folded himself into the one chair not occupied by paper, set the cane across his knees, and looked at her as though they had all the time in the world. "You left without saying goodbye," she said. It came out before she could stop it—not the cold line she'd practiced but the raw, stupid truth, and she hated the way it landed in the small room, hated more the flicker of something across his face that might have been guilt if he were the kind of creature who felt it. "I left," he agreed, "because the alternative was watching you decide you couldn't trust me. I find I'd rather not witness that particular verdict in real time." "That's a very elegant way of saying you ran." "I'm half-demon, Rory. We don't run. We *withdraw strategically*." The corner of his mouth curved, but his eyes didn't follow, and that small dissonance was worse than if he'd laughed. "You're angry. You're entitled. I gave you reason." "You gave me a great deal of reason." She crossed her arms and stayed standing, because sitting felt like surrender and she had so little ground left to hold. Ptolemy leapt onto the table and settled atop a pile of Eva's notes, tail flicking. "You knew what Evan was. You knew before I did, didn't you? You knew what he'd become, and you let me—" "I *suspected*." The word came sharp, the first crack in the lacquered calm. He leaned forward, elbows on his knees, the cane sliding against his palm. "I suspected, and I had nothing I could prove, and I knew that if I told you what I suspected without proof, you'd think I was the same kind of man who'd already taught you to flinch. So I waited. I gathered. And while I was being so very careful, the situation moved faster than I did." A muscle worked in his jaw. "That is the closest thing to an apology I have ever offered another living person. I'd encourage you to take it seriously." The flat went quiet. Somewhere below, a pan clattered in the curry-house kitchen; somewhere outside, a bus sighed to a halt and pulled away. Rory became aware of her own heartbeat, too loud, too fast, the betraying warmth climbing her throat. "Don't," she said softly. "Don't what?" "Don't be *reasonable*. It would be so much easier if you'd just be the villain I'd decided you were." He stood. He did it slowly, the way he did everything, and the small room seemed to shrink around the breadth of him until there was nowhere to look that wasn't him. The mismatched eyes held her—amber and black, light and absence, the two halves of him she'd never managed to reconcile and had stopped, somewhere along the way, wanting to. "I am not a good man," Lucien said. "I want to be very clear, because I think you've begun to imagine I am, and that misunderstanding will only hurt you. I deal in secrets. I trade in other people's desperation. I have done things that would put that crescent scar on your wrist to shame, and I would do them again." He was close now, close enough that she could see the faint silver at the edge of his black iris, the thing that wasn't quite human. "But I have never lied to you. And I came back across a continent because someone is hunting you with intent, and I find I cannot abide the thought of arriving too late twice." The space between them had become a held breath. She could feel the heat coming off him, could see the pulse at his throat moving quicker than his composed face would ever admit. "That's not the same as caring," she whispered. "No," he said. "It's worse. Caring, I could manage." His hand rose—stopped—hovered an inch from her cheek as though awaiting a permission she hadn't yet decided to give. "Tell me to leave, Rory. The bolts are right there. I'll go, and I'll handle this from a distance where it's safer for both of us, and you'll never have to forgive me." She looked at his hand. She looked at the door, the three open bolts gleaming dully in the lamplight, the whole easy ruin of the night just waiting on the other side. "Don't go," she said. And the inch between his hand and her face closed.
