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.

Write the scene from the moment the door opens. Use the codex entries above as your world reference for characters and setting. Only include the prose of the scene without any markdown or commentary.

The third deadbolt always stuck. Rory wrestled it free with the heel of her hand, muttering a curse she'd inherited from her father, and only then registered the shape on the other side of the peephole — a slash of charcoal, a glint of pale hair under the stairwell's dying bulb. She froze with her fingers on the chain. She could have left it. She could have pretended she'd never crossed the room, pretended she was still curled on Eva's sagging sofa with a takeaway carton going cold against her knee and Ptolemy kneading the blanket beside her. The smell of cumin and frying onions drifted up through the floorboards from the curry house below, the same smell that had become, over these weeks, something almost like home. But the chain was already off. And he knew she was there. He always knew. She opened the door. Lucien Moreau stood on the landing as though he'd been poured into it, one gloved hand resting atop the ivory handle of his cane, the other tucked into the pocket of a suit that probably cost more than three months of her wages from the Golden Empress. The amber eye caught the light. The black one drank it. He looked at her the way he always had — like she was a ledger he was tallying, a sum he hadn't finished. "Aurora," he said. The accent rolled over the vowels of her name, warm and unhurried. *Oh-roh-rah.* No one else made it sound like that. "You don't get to call me that." Her voice came out steadier than she felt. "Not anymore." "Rory, then." A faint incline of his head, conceding the point with the ease of a man who conceded nothing. "May I come in?" "How did you find me?" "You are asking the wrong man if you expect that to be difficult." A ghost of a smile touched the corner of his mouth and then thought better of it. "Three months, Rory. I had begun to think you'd left the city altogether." "That was rather the idea." The smile died entirely. Behind him, on the stairs, a door slammed somewhere and a baby started crying, and the ordinary noise of Brick Lane filled the silence she refused to. "It's cold out here," he said. "Good." He sighed — a small, theatrical thing — and shifted his weight onto the cane, and she saw then what she hadn't from the peephole: the careful way he favored his left leg, the faint stiffness in his shoulders. Lucien did not show pain. It was, she'd long ago decided, the most fundamental thing about him. He arranged himself like a man who'd never once been caught off guard, and the fact that he was leaning, here, now, told her more than any words could. "You're hurt," she said. "I'm fine." "You're leaning on that thing like it's the only reason you're upright." "How flattering, that you still watch so closely." She hated that he was right. She hated, more, that her hand had already loosened on the door, that her body had already decided what her mouth was still pretending to debate. Ptolemy padded up behind her ankles and butted his head against Lucien's polished shoe, traitorous beast, purring like an engine. "Even the cat," Lucien murmured, looking down at it. "I am winning everyone over tonight except the one who matters." "Don't." The word cracked out of her before she could stop it. "Don't do that. The charm. The — *that.* It doesn't work on me anymore." He looked up. For one unguarded second the amber eye went soft, and something moved behind it that she didn't have a name for and didn't want one. "No," he agreed quietly. "I don't suppose it ever truly did. That was always the trouble with you." She stepped back. It wasn't surrender. She told herself it wasn't surrender, even as she held the door wide and let the cold draft of the landing pour past her into Eva's cramped little kingdom of books. "Five minutes," she said. "And you don't sit on the good chair, it's the only one that doesn't wobble and I'm not having you bleed on it." "I'm not bleeding." "You're limping. Sit on the floor for all I care." He came in. He had to duck slightly under the low lintel — five-eleven in a doorway built for shorter, harder lives — and the flat seemed to shrink around him, the way a room always did when Lucien entered it. He took in the towers of scrolls, the research notes pinned to every wall, Eva's chaos of borrowed knowledge, and she watched him catalogue all of it in a single sweep and say nothing. She shut the door. Slid the first deadbolt. Stopped, with her hand on the second, and decided against it. A small thing. He noticed it anyway. He noticed everything. "Eva's not here," she said, turning. "If that's who you came to—" "I came for you." The kitchen tap was dripping. She'd been meaning to fix it for a week. The drip filled the space where her answer should have gone, and she stood with her back to the door and her arms crossed over the oversized jumper she slept in, and looked at this man she had spent three months teaching herself to stop dreaming about. "You don't get to say that either," she said. But it came out thin. "I know what I am not permitted to say." He crossed to the window, slow, and lowered himself onto the broad sill with the cane braced between his knees, and only when he was settled did she see how white his knuckles had been. "You made the rules very clear the last time. I have thought about them. Often." A pause. "I have also broken several of them by being here, so perhaps we may dispense with the pretense that I am a man who follows rules." "What do you want, Lucien?" He was quiet for a moment. Outside, a bus groaned past, and its headlights swung across the ceiling and over the planes of his face — the scar of light in the amber eye, the dark unknowable pool of the other — and he looked, just then, almost mortal. Almost like the half of him that bled. "Someone is asking questions about you in the wrong places," he said. "Using a name you have not used in a very long time. *Malphora.*" The carton of cold noodles seemed very far away. The warmth of the sofa. The pretending. "That's not possible," she whispered. "Nobody knows that name." "Someone does." He met her eyes, and for once there was no charm in it, no ledger, nothing but the plain hard truth he'd carried up three flights of stairs on a leg that didn't want to hold him. "And so I came. Because whatever you have decided about me, Rory — whatever I deserve to have you decide — I was not going to let you hear it from anyone else." Ptolemy leapt up onto the sill beside him and curled into the curve of his hip as though he belonged there, and Rory stood in the middle of Eva's borrowed flat with all her careful distance crumbling like wet paper, and could not for the life of her remember why she'd ever shut the door on him at all.
