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 after another, three distinct clicks, and then the door swung inward. Lucien stood on the landing with his weight settled on the cane, the amber eye catching the bare bulb above the curry house stairwell. Rain darkened the shoulders of his charcoal suit. He didn't smile. "You changed the locks," he said. "I added two." Aurora kept one hand on the door, the other braced against the frame, her body filling the gap. Ptolemy wound between her ankles, indifferent to the tension. "What are you doing here, Lucien?" "May I come in, or shall we conduct this on Eva's doorstep for the benefit of the curry house?" Below them, oil hissed in a pan and someone shouted an order in Bengali. She stepped back. Not an invitation so much as a surrender to the cold air pushing past him into the flat. He moved inside the way he moved everywhere — measured, unhurried, as though the room had been waiting for him. His gaze swept the towers of books, the scrolls unspooled across the table, the research notes pinned to the wall in Eva's cramped hand. He took it in and filed it away. He always did. "She's not here," Aurora said, shutting the door. She left the deadbolts open. A small thing. He noticed that too. "If you came for Eva—" "I came for you." The words sat in the air between them. Ptolemy leapt onto a stack of grimoires and began grooming a paw. "Last time," she said, "you told me I was a liability. You said working with me would get us both killed and that you preferred to die for reasons of your own choosing." "I recall the conversation." "You walked out." "I did." He set the tip of the cane against the floorboards and leaned on it, the ivory handle bright under his palm. "I've had occasion to revisit my position." She crossed her arms. "How convenient. Something's gone wrong and now you remember my number." "Aurora." "Don't." Her voice didn't rise. That was the thing about Rory — the colder she got, the quieter. "You don't get to say it like that. Like the last six weeks didn't happen." He was silent. The amber eye held her; the black one gave back nothing, a hole in his face where light went to die. She'd hated that about him once. Then she'd stopped hating it. That had been the trouble. "I was wrong," he said. She laughed, short and disbelieving. "Say that again. I want to make sure I heard it." "I won't. Once is the limit of my dignity." He moved to the table, traced a gloved finger along the edge of a scroll without disturbing it. "I told you that you were a liability because it was easier than the truth. The truth was that I'd grown accustomed to you. I don't grow accustomed to people. It's bad for the trade and worse for the soul, assuming I've kept enough of one to ruin." Rain ticked against the window. Outside, Brick Lane glistened orange under the streetlamps. "That's not an apology," she said. "No. It's an explanation. You're clever enough to know the difference, and I'm coward enough to offer the cheaper of the two." She pulled out a chair and sat, not because her legs had failed her but because standing made her feel like she was bracing for a blow. "Why now, Lucien?" He turned. For the first time something cracked across that composed face — a tightness at the jaw, a flicker. "Because I spent six weeks telling myself the decision was sound. And then I heard your name come through a channel it had no business being in, attached to a price, and I discovered that my sound decision had the structural integrity of wet paper." Her stomach dropped, but she kept her face still. "A price." "Someone is asking after you. Carefully. The kind of careful that costs money and means business." He stepped closer, and now the cane was an afterthought, his hand loose on it. "I don't know who. I intend to. But I couldn't very well learn it from across the city while pretending I'd stopped caring whether you lived." "So this is about keeping me alive." "This is about the fact," he said, low, "that I left you on a different doorstep six weeks ago and I have regretted every hour since. The danger is merely the excuse I required to admit it. I'm a man who needs excuses, Aurora. I've made a career of them." She looked at him. The platinum hair was darker at the edges where the rain had got to it. There was a line between his brows she didn't remember being so deep. "You hurt me," she said. Plain. No drama in it. "I want you to hear that before anything else. You looked me in the face and told me I didn't matter, and I believed you, because you're very good at being believed." "I know." "And I packed up what we'd started and I told myself I'd been stupid to think a man like you—" She stopped. Pressed her lips together. "You don't get to undo that with a warning and a confession." "I'm not asking to undo it." He crouched then, slow, bringing himself level with her where she sat, and the cane lay forgotten across his knees. Up close the heterochromia was startling — the amber warm, the black bottomless, both of them fixed on her. "I'm asking whether there's any version of the next ten minutes in which you don't throw me down the stairs. I'll take the rest as it comes." Ptolemy abandoned the grimoires and padded over to butt his head against Lucien's free hand. The cat had always liked him. Traitor. Aurora exhaled. Something in her chest, wound tight for six weeks, gave a fraction. Not forgiveness. The room before forgiveness. "Ten minutes," she said. "And you tell me everything you know about the price on my head. No charm. No omissions." "On my mother's grave." "Your mother's alive." The corner of his mouth moved. "On the inconvenience of that fact, then." She almost smiled. She hated that she almost smiled. "Sit somewhere I can see you," she said, and pointed at the chair across the table. "Not close. I'm not ready for close." He rose, and obeyed, and the space between them stayed exactly as wide as she'd set it. For now.
