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.

Two people who parted on complicated terms are forced together again when one shows up unannounced at the other's flat. There's history between them — attraction, hurt, and things left unsaid. 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 knock came at half past eleven, three slow raps that didn't belong to anyone Rory expected. Eva was in Lisbon until Sunday. The only other person with a key to the flat on Brick Lane was Rory herself, and she had come only to feed Ptolemy and check that the radiator wasn't leaking again. She stood in the narrow hallway with a tin of cat food in one hand and the other on the first deadbolt. Downstairs, the curry house was closing up. Someone was hosing the pavement, and the smell of cumin and scorched butter drifted up through the floorboards. The knock came again. Patient. Almost courteous. She knew that knock. She had known it for three years, and she had spent the last eight months trying to forget it. "Go away, Lucien," she said through the wood. A pause. "You always did have a gift for knowing who was on the other side of a door." His voice was exactly as she remembered it: low, unhurried, with the French vowels worn smooth by years of speaking English in rooms where people lied to him. It went straight through her, the way it always had, and she hated that more than anything. She turned the first bolt. Then the second. The third stuck, the way Eva's always did, and she had to wrestle it with the heel of her hand while he waited on the landing. She could feel him there without looking, the way she could feel weather coming. When she finally pulled the door open, she made herself look at him. He had not changed. Charcoal suit, cut so precisely it might have been poured onto him. Platinum hair combed back from a face that could have belonged to a painting, if the painting had been bored and dangerous. The ivory-handled cane was in his left hand, and his mismatched eyes, one amber and one black as a moonless sea, moved over her face the way a man reads a letter he has already memorised. "Rory," he said. Nobody else called her that anymore. Her friends from Cardiff had stopped when she moved, and Eva had never been able to manage it, so she'd always said Aurora with a flourish. Only Lucien had shortened it, the first night they met, and somehow made it sound like a secret. "You're not supposed to be here," she said. "No." He shifted his weight, and the cane tapped once against the floorboards. "I'm told that's been a theme." "Who told you I was here?" "Nobody. I guessed. Eva's flat, Eva's cat, Eva's friend who has apparently appointed herself keeper of both." The corner of his mouth moved, not quite a smile. "You always did take the sensible hiding places. It's the one thing I could never fault." "I'm not hiding." "No?" "I work. I have a flat. I have a life that doesn't involve—" She stopped. She had been about to say *you*, and she would not give him the satisfaction of hearing it. Something moved behind his eyes. He glanced past her, into the cramped front room, where books and scrolls and yellowed notes covered every surface. A stack of research on the sofa had tipped over. Ptolemy, grey and indignant, sat on top of the pile and blinked at them both. "She's still doing it," Lucien said quietly. "Eva. Still chasing the Malphora." Rory's breath caught at the name. She didn't let it show on her face. "Don't." "I'm not here about that." "Then what are you here about?" He was silent for a long moment. Downstairs, the hosepipe stopped. The street went quiet except for a taxi somewhere toward Whitechapel. "I needed to see you," he said at last. "I didn't know how else to say it, so I came to the one door I was certain you'd open." It was the wrong thing to say. Or the right thing, and she had spent eight months convincing herself it wouldn't matter whether it was right or wrong. The last time they had spoken properly, he had stood in the rain outside Silas' bar with his hands in his pockets and told her she was making a mistake, that the thing she'd been running from would find her wherever she went. She had told him that he didn't get to decide what she ran from. Then she had walked upstairs and shut the door, and she had not looked back, because looking back was how people got hurt. "You should have called," she said. "You'd have hung up." "Yes." "Then I'm glad I didn't." She folded her arms, partly to stop her hands from shaking and partly as a barrier. Her left wrist ached where the old crescent scar was, the way it always did when she was anxious, a reminder of a childhood accident that she'd never told him the whole story of. He had noticed it on their first night together, traced it with his thumb, and asked her nothing. She had loved him a little for that. She had loved him a lot more for the way he'd asked nothing about anything else, either, which had made it so easy to keep the truth locked away. "Say it, then," she said. "Whatever you came to say." Lucien looked at her for a long moment, and for the first time since she'd opened the door, he seemed unsure of himself. "I was wrong," he said. "About the rain. About you running. I thought I was protecting you." His jaw tightened. "I was only afraid you'd stop needing me to." The words landed heavier than she'd expected. Rory had imagined a hundred versions of this moment, most of them with her shouting, a few with her crying, one where she simply closed the door and never thought about him again. In none of them had he looked at her like this, as though she were the only solid thing in a city that kept shifting underfoot. "That's not fair," she whispered. "No," he agreed. "Nothing about us was ever fair." She should close the door. She knew the exact weight of it in her hand, the three bolts waiting to be slid home, the sensible distance she could put between them in one clean motion. Instead she stepped back, just far enough to let him in, and hated herself for how easily her body had decided before her mind could object.
