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 deadbolts gave one at a time, three sharp clicks, before the door swung inward and there he stood on the landing, rain darkening the shoulders of his charcoal suit. "You changed the locks," Lucien said. "Eva did. After the last time someone broke in." Aurora kept one hand on the door frame and the other on the edge of the door itself, the gap between them no wider than her shoulders. "Which begs the question of how you found this place at all." "I'm an information broker, Aurora. Finding people is the entire profession." Water beaded on the ivory handle of his cane where his gloved fingers wrapped it. "May I come in, or shall we conduct this on the stairs while the curry house below us perfumes the whole conversation?" She didn't move. Ptolemy wound between her ankles, indifferent to the tension, and she nudged the cat back with the side of her foot. "You don't get to just show up." "And yet." He tipped his head, the platinum hair catching the weak hallway light. The amber eye held her; the black one swallowed everything. "I tried calling. Three times. You let it ring out." "That was the message." "I'm fluent in four languages and that one I understood perfectly." A faint pull at the corner of his mouth, not quite a smile. "I came anyway. Because what I have to say I will not say to a phone, and certainly not leave on one." The rain found its rhythm against the window at the end of the corridor. Aurora studied him — the careful composure, the way he held himself a fraction too straight, the cane planted like he needed it for more than affect tonight. She had spent six weeks teaching herself not to notice these things about him. Six weeks dismantling, brick by brick, the particular foolishness of caring whether Lucien Moreau came or went. She stepped back and let the door swing wide. "Wipe your feet." He did, with theatrical precision, and crossed the threshold into the chaos of Eva's flat. Books stacked to hip height. Scrolls in a basket meant for laundry. The lamp she'd left burning threw everything gold and crooked. Lucien took it in with a single sweep of his gaze, the way he took in every room, cataloguing exits and weaknesses and the small confessions a space made about the person inside it. "Charming," he said. "You've been hiding here the whole time." "I haven't been hiding. I've been living. There's a difference, though I wouldn't expect you to know it." She shut the door, threw the top deadbolt out of habit, then hated that she'd done it in front of him. "Say what you came to say." He set the cane against the arm of the sofa and peeled off his gloves one finger at a time. The amber eye never left her. "In Marseille," he started. "Don't." "You asked me to say what I came to say." "Not that." She folded her arms. "Anything but that." "There's nothing else worth the trip." He laid the gloves over the cane's handle, deliberate, buying himself the seconds. "You walked out of that hotel and onto a train and you didn't look back, and I let you, because letting you was easier than the alternative. I've had six weeks to decide whether that was the smartest thing I've ever done or the most cowardly." "And?" "Both. Usually it's both." She laughed, a short ugly sound that surprised her. "You came all this way to be honest. Should I mark the calendar." "Aurora." He took a step and she took one back, and they both heard the floorboard groan under her heel, the small comedy of it. He stopped. Spread his hands. "I'm not going to chase you across the room. I'm not built for farce." "No. You're built for leaving people in train stations with half a sentence finished." "That sentence." His jaw tightened, the only crack in the lacquer of him. "You want to know how it ended." "I stopped wanting to know the moment you didn't tell me." "Liar." Said gently. Said like a man laying down a card he'd held too long. "You've thought about it every night. I've thought about it every night, and I am a creature who does not lose sleep, Aurora. I'm half a thing that doesn't even need it. And still." The rain pressed harder. Ptolemy leapt onto the back of the sofa and settled there, tail flicking, watching them both as though they were the evening's entertainment. "You hurt me," she said. The words came out smaller than she meant. "I don't think you understand that, because I don't think it occurs to you that you can. You move through the world like you're behind glass. And I let myself believe I was on your side of it." "You were." "For one night." "For more than that." He shook his head, slow. "I told myself you'd be safer the further you got from me. People who matter to me have a poor survival rate. It's not modesty. It's arithmetic." He looked away then, the first time, toward the window and the grey sheet of weather behind it. "But arithmetic is a coward's mathematics. I came to tell you I was wrong, and that I'm not asking you to forgive it, only to know it. The rest is yours." Aurora's arms loosened. She didn't decide to let them. They simply unfolded, the way a fist does when there's nothing left to hold. "You can't say things like that and expect me to have an answer ready." "I don't expect anything ready. I expect you to make me wait, which I deserve, and which I'll do." He picked the gloves back up, turned them over in his hands. "I have a room at the Connaught. I'll be there a week. After that I go where the work takes me, as I always have." "And if I don't come." He met her eyes, both of his — the amber and the black, the human half and the other. "Then I'll have told the truth once in my life, and to the right person. That's more than most of my kind manage." A breath. "It would have to be enough." She stood there in the lamplight with the cat watching and the rain coming down, and she found that she had no clever thing to say, no cool-headed deflection, none of the quick footwork she was known for. Only the crescent scar on her wrist, which she pressed her thumb against without thinking, the way she had since she was a child and the ground went uncertain under her. "Don't go yet," she said. Lucien stopped with the gloves half on. "Don't read into it. I'm not — I haven't decided anything." She pushed her hair back from her face. "But you came in out of the rain and I'm not turning you back into it tonight. There's tea. There's a kettle somewhere under all this." She gestured at the disaster of Eva's kitchen. "Sit down before I change my mind." For a moment he didn't move. Then he set the gloves down again, lowered himself onto the edge of the sofa, careful of the books, and Ptolemy descended at once into his lap as though they were old conspirators. "The cat likes me," he said. "The cat has terrible judgement." She turned toward the kettle so he wouldn't see her face. "Runs in the household, apparently."
