You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The three deadbolts gave way one after another, each one a small surrender, and when Aurora pulled the door open the cold from the stairwell rushed in past her ankles. Lucien stood on the landing with his cane planted before him and rain dotting the shoulders of his charcoal suit. The single bulb above the curry house door caught the amber of his right eye and left the black one in shadow, so that for a moment he looked like two different men deciding whether to step inside. "You changed the locks," he said. "Eva changed them." She kept one hand on the door, the gap no wider than her body. "What do you want, Lucien?" "To stand somewhere that isn't this stairwell. The gentleman downstairs is frying onions and I've a sensitive constitution." Behind her, Ptolemy wound a figure-eight between her shins, purring at the stranger he could smell. Traitor. Aurora glanced back into the flat — the slope of books, the scrolls she'd half-unrolled across the table, the mug of tea going cold — and weighed the cost of letting him over the threshold against the cost of the conversation he'd start if she didn't. She stepped aside. He came in the way he did everything, without hurry, and the cane tapped twice against the floorboards before he found a clear patch of carpet to claim. His gaze moved over the chaos of paper, then to her, then to the tea. "You're still drinking it with too much milk," he said. "You don't get to comment on how I take my tea anymore." "No." He set the cane against the arm of the sofa. "I suppose I don't." The flat had never felt small until he was in it. Aurora folded her arms and stayed near the door, the deadbolts cold against her shoulder blade. "Three months," she said. "Three months and not a word, and now you're dripping on Eva's rug at eleven at night. So either someone's dying or you want something, and I've learned to assume it's the second one." "Both, as it happens." He smiled, but it didn't reach the black eye. "May I sit, or are we conducting this from opposite corners like duellists?" "Suit yourself." He lowered himself onto the sofa, careful with the left leg, and she pretended not to notice the way he was careful. Ptolemy leapt up beside him and Lucien laid one gloved hand on the cat's back as if they were old conspirators. "You look well," he said. "Better than London deserves." "Don't." "Don't what?" "That. The—" She gestured at the whole of him, the voice, the easy charm worn smooth as a river stone. "Whatever this is. You walked out of Silas' bar and you didn't look back, and I told myself that was the cleanest thing that had ever happened to me. Don't ruin it by being charming." The smile faded. He took his time pulling off the glove, finger by finger, and when his bare hand returned to the cat's fur the gesture was gentler than anything he'd said. "I didn't walk out," he said. "I was made to leave. There's a difference, though I grant you it looks the same from where you were standing." "Made to leave." "There were people who would have used you to reach me. The kindest thing I could do was make it look as though you meant nothing." He lifted his eyes to hers. "It was not a convincing performance, for what it's worth. I have rather lost my talent for lying to you." Aurora's throat tightened, and she hated it, hated that three words from him could do what three months of silence hadn't. She crossed to the table because she needed somewhere to put her hands, and began stacking the scrolls that didn't need stacking. "You could have sent word," she said, not looking at him. "A note. One line. *I'm not dead, don't waste your worry.* I'd have torn it up but I'd have had it." "Would you have believed it?" "No." She set the scroll down hard. "But I'd have had it." The rain found a rhythm against the window. Somewhere below, the curry house clattered through its closing, pans into sinks, a man laughing at something in a language she didn't speak. Lucien rose. She heard the cane, the careful shift of weight, and then he was close enough that she caught the scent of him under the rain — cedar, smoke, something darker beneath that she'd never been able to name. "You asked what I want," he said. "I'll tell you, and then you may throw me back down the stairs if you like. I want the thing I told myself I couldn't have, because I've spent three months learning that the danger I was protecting you from is nothing beside the danger of living without you in it. That is the dying part, Aurora. I've been dying of it quite slowly." She turned. He was nearer than she'd judged, that mismatched gaze fixed on her, and the practised charm had gone out of his face entirely. What was left looked younger and far less sure. "You don't get to say things like that," she whispered. "Not after." "I know." "You broke something." "I know that too." His hand lifted, hovered near her jaw without touching. "I'm not asking you to mend it tonight. I'm asking you to let me stand here and feel what I refused myself, for as long as you'll allow it. A minute. I'll take a minute and call it a fortune." Her heart slammed against her ribs hard enough that he must have heard it. She thought of every reason — the locks, the hurt, the version of herself she'd built in his absence, careful and contained. Then she thought of the way the stairwell light had split his face into two men, and how she'd known both of them, and had wanted both anyway. "One minute," she said. He let out a breath like a man set down from a great height. His thumb came to rest, finally, at the corner of her mouth, and the leather-warm of his bare hand was the only soft thing in the cold flat. "You're counting?" he murmured. "I'm counting." "Then I'd best not waste it."
