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, metal sliding against metal, and then the door opened to a face Rory had spent two months learning to forget. Lucien stood in the dim corridor with rain darkening the shoulders of his charcoal suit, his platinum hair flattened against his temple. The ivory cane hung loose in one hand. He looked at her the way a man looks at something he'd lost and never expected to find lying in the street. "You changed the locks," he said. "You noticed." "Three deadbolts. Eva's idea or yours?" Rory kept her hand on the edge of the door, the gap no wider than her shoulders. Ptolemy wove between her ankles, indifferent to the storm of it, and slipped out to investigate the visitor's polished shoes. "What do you want, Lucien?" "A conversation. Five minutes." His amber eye caught the hallway light; the black one swallowed it. "You can keep the chain on if it makes you feel safer." "There's no chain." "Then you'll have to make a choice." She hated that he could still do this — turn a doorway into a negotiation, narrow the whole world down to whether or not she let him in. She'd watched him do it to bookmakers and blood-sellers and worse. She'd told herself she was different. She'd been wrong about that, and she'd promised herself she wouldn't be wrong about it twice. The rain answered for her. A gust drove it sideways down the corridor, spattering his back, and he didn't flinch. Just waited. Patient as a debt. "Five minutes," she said, and stepped back. He came in slowly, drinking the place in the way he drank in everything — the books stacked against the skirting, the scrolls bound with twine, the research notes pinned to the wall in Eva's frantic hand. He set the cane against the bookcase and didn't sit. "She's not here," Rory said. "If that's who you came for." "It isn't." "Then you wasted a trip across the river." "Aurora." Her full name, the way only he said it, the vowels rounded by Marseille. "I came because of what happened at the warehouse." She crossed her arms. The crescent scar on her wrist caught the lamplight. "Nothing happened at the warehouse. You made sure of that. You sent me out the back and you closed the door and you let me think—" She stopped. Started again, flatter. "I waited on Commercial Road for an hour. In the cold. Watching the door you walked back through." "I know." "You don't know. You weren't the one waiting." "I was the one who didn't come out for three days." He said it without weight, which was how she knew it cost him. "There were terms. The kind you settle in person or you don't settle at all. If you'd been there, they'd have used you. A leash around my neck with your name on it." He turned his palm up, the gesture economical. "So I cut the leash before they could fit it." "You could have told me." "You'd have argued." "Yes." Her voice cracked on the word and she despised it. "I'd have argued. That's what people do, Lucien, when they care whether the other one walks out of a room. They argue. They don't get handed out the back like a parcel." Ptolemy hopped onto the arm of the sofa and watched them both, tail twitching. Lucien moved then — not toward her, but to the window, where the rain ran down the glass in long seams. The neon from the curry house below painted his face in shifts of red and gold. "In Marseille," he said, "my father taught me one useful thing before he went back to Avaros. He said affection is a liability you carry on your own books. Never the other person's." A thin smile. "I've kept those books balanced for thirty-two years." "And how's that working out?" "Poorly." He turned. The amber eye found her and held. "I stood in that warehouse with the door shut and I found I could not balance you. I tried. The figures wouldn't come right. So I told myself you were a risk I'd retired, and I went home, and I did not knock on this door for two months because I am, in most things that matter, a coward." The flat was very quiet. The rain filled it. "Don't," Rory said. "Don't what?" "Don't be honest now. You don't get to be a coward for two months and honest for five minutes and have it even out." "No," he agreed. "It doesn't even out. That's rather the point." He took a step, and the floorboard complained beneath him, and he stopped as if the sound were a boundary. "I'm not asking it to even out. I'm asking you to know it. There's a difference." She looked at him — really looked, the way she'd trained herself not to. The wet hair. The shadows beneath his eyes that no tailored suit could press out. The cane left behind by the door, which she'd never once seen him do, because the cane was the blade and the blade was how he survived. He'd come into her flat and set down the only weapon he carried. "You left it by the door," she said. "What?" "The cane. You never leave it where you can't reach it." Something shifted in his face. "No," he said. "I don't." The two months pressed against her chest, every hour of them, every time she'd reached for her phone and put it down again, every time Eva had watched her not say his name across the breakfast table. She'd built three deadbolts against this exact moment. She'd known, on some level beneath the planning, that none of them would hold. "Five minutes is up," she said. "I know." Neither of them moved toward the door. Rory let out a breath she felt she'd been holding since Commercial Road. "There's tea," she said. "It's terrible. Eva buys the cheapest bags in the shop and I haven't had the energy to argue with her about it." The corner of his mouth lifted, careful, like a man testing ice. "I've survived worse." "Have you, though." "Recently," he said, "no." And he stayed where he stood, hands open and empty, waiting on her the way he'd waited in the corridor — except this time the door was already shut behind him, and the only thing left to decide was whether she crossed the room.
