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 way one at a time—three sharp clicks—and the door swung inward to reveal Lucien Moreau leaning against the frame as though he'd done nothing more taxing than stroll across the street. "You changed the locks," he said. "Two of them, anyway. The brass one's new." Aurora kept her hand on the edge of the door, ready to swing it shut again. "Funny. I changed them after you left." "Coincidence." "Was it." Behind her, Ptolemy threaded between her ankles and let out a low complaint at the cold air spilling in from the stairwell. The smell of frying cumin rose up from the curry house below, thick enough to taste. Lucien's gaze flicked past her to the chaos of the flat—books stacked spine-up on every surface, the half-eaten toast abandoned on the arm of the sofa, the lamp she'd never quite gotten to work. "You going to make me stand on the landing?" "I'm considering it." He smiled, and that was the worst of it, because the smile reached the amber eye and left the black one cold the way it always had, and she'd spent six weeks trying to forget how that particular asymmetry made her stomach drop. "It's raining," he said. "You're half demon. You'll survive a little water." "Aurora." She hated how he said her name. Three syllables given the full weight of his accent, the r's softened, the whole thing turned into something that sounded like an apology he had no intention of making. She let go of the door and stepped back. "Five minutes. Wipe your feet." He came in, cane first, the ivory handle catching the lamplight. He didn't wipe his feet. Of course he didn't. He set the cane against the bookcase and turned a slow circle, taking in the research notes pinned to the wall, the scrolls she'd borrowed from Eva and never returned, the general evidence of a life that had kept moving without him. "You've been busy." "Some of us work." "I work." "You collect secrets and sell them to the highest bidder. That's not the same thing." "It pays better." He picked up one of the scrolls, glanced at the script, set it down again with a precision that suggested he'd read every word in the half-second he'd held it. "You're researching Avaros sigils. Should I be flattered or worried?" "Neither. Put that down." "I did." He turned to face her fully. The charcoal suit was immaculate, the collar crisp, not a single platinum hair out of place, and she resented every inch of the effort because it meant he'd dressed before coming, meant he'd stood in front of a mirror somewhere across the city and decided how he wanted her to see him. "You look tired." "I look fine." "You look like you haven't slept since Tuesday." "That's because someone left me a voicemail at three in the morning saying he had something to tell me and then didn't call back for six weeks." She crossed her arms. "So. Here you are. Tell me." Something moved behind his face—just for a second, the practiced ease slipping, like a stone dropping through still water. He bent and scooped up Ptolemy, who permitted it with the long-suffering dignity of a cat who'd been abandoned by everyone in this room at least once. "You kept the cat." "He came with the flat. Don't change the subject." "I'm not changing it. I'm arriving at it slowly." He scratched the tabby under the chin and the traitorous animal began to purr. "The voicemail. Yes. I owe you an explanation for the voicemail." "You owe me a lot of things." "I'm aware." He set Ptolemy down on the back of the sofa and the cat stalked off, tail high. Lucien straightened his cuffs—a tell, she'd learned, the thing he did with his hands when he wanted to look as if his hands weren't a problem. "I left because staying was going to get you killed. I want that on the record before you say anything else." "On whose record? There's no record, Lucien. There's just me, standing in my friend's kitchen at half nine on a Thursday, listening to you justify vanishing." "It wasn't a justification. It was the truth." "They're not mutually exclusive." He laughed—short, surprised, genuine, and she hated that too, because for one stupid moment it pulled the corner of her own mouth before she clamped down on it. "There she is," he said quietly. "Don't." "Don't what?" "Don't do the thing where you find the one true sentence and use it like a key. I know the trick. I watched you do it to other people for months." She moved past him to the kettle, more for something to hold than from any intention to make tea, and filled it at the tap with her back to him. "You don't get to come back and be charming. You forfeited charming." "I didn't come back to be charming." "Then why did you come back?" The kettle's hiss filled the gap. She didn't turn around. She heard him take a step closer—not the cane, just the soft sound of his shoe on the warped floorboard, the one near the radiator that always gave him away because she'd never told him it was there. "Because the thing I needed to tell you isn't the kind of thing you leave on a voicemail," he said. "And because every job I've taken since June has put me within a half-mile of this flat, and I've been telling myself it was the work, and I'm tired of lying to myself when I'm already so good at lying to everyone else." She gripped the edge of the counter. The scar on her wrist caught the light, that pale crescent, and she watched it instead of him. "That's a very nice speech." "It isn't a speech. I didn't rehearse it." A pause. "I rehearsed three others and threw them out on the stairs." That, finally, turned her around. He stood close enough that she could see the rain still beaded on his shoulders, the faint shadow of exhaustion under both eyes, the amber one and the black one alike. "You threw out three speeches," she said. "On the second landing. There's a man down there who thinks I'm unwell." "You are unwell. You're a half-demon information broker who flirts with women he's actively endangering." "Only one woman." He held her gaze. "And I'd very much like to stop endangering her, if she'll let me explain how." The kettle clicked off. Neither of them moved toward it.
