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 third deadbolt gave way with a sound like a snapped knuckle, and Aurora pulled the door open expecting Eva's takeaway order, or perhaps the landlord come to complain about Ptolemy yowling at the small hours. Instead she got a charcoal suit and a smile that had cost her three sleepless nights the last time she'd seen it. "Bonsoir, Rory." "No." She moved to shut the door. Lucien set the tip of his cane against it, an inch of ivory holding back the whole weight of her decision. He didn't push. He never pushed. That was the maddening thing about him — he simply waited, one amber eye and one black one fixed on her, until the world rearranged itself to his liking. "You haven't asked why I'm here." "Because I don't care why you're here." She leaned harder. The door didn't budge. "And because the answer's always the same. Someone needs something. You need someone to fetch it. And somehow I'm the someone." "Cruel." He tilted his head. "Accurate, but cruel." Down the corridor, the curry house exhaled its evening of cardamom and frying onions up through the floorboards. Ptolemy appeared at Aurora's ankles, regarded the visitor with feline contempt, and slunk back toward the kitchen. "Five minutes," Lucien said. "Then I leave, and you may bolt all three of your locks behind me and pretend Marseille never happened." Her jaw tightened. He'd chosen that word on purpose. Marseille. The harbour at four in the morning, the salt and the diesel, his hand at the small of her back as the men with the wrong sort of patience closed in. The way he'd kissed her on the gangway — not for her, she'd told herself a hundred times since, but for the witnesses, to sell the lie that they were lovers fleeing rather than thieves running. She'd believed her own version right up until she'd caught him watching her sleep on the ferry, and the look on his face had not belonged to any lie. Then London. Then nothing. Then six weeks of silence that she'd dressed up as relief. "Four minutes," she said, and stepped back. He came in the way he came into everywhere — as though the room had been arranged in anticipation of him. His gaze moved across Eva's chaos: the towers of books, the scrolls bleeding off the table edges, the research notes pinned to every flat surface in Eva's spidering hand. "She's still chasing the Avaros texts." "Don't touch anything." "I wouldn't dream of it." He set the cane against the doorframe and didn't sit. "How is your wrist?" The question landed somewhere under her ribs. She folded her arms, hiding the small crescent scar on the left, the old childhood thing he had no business remembering. "Three minutes." "You're counting fast." "You taught me." She held his stare. "What do you want, Lucien?" He reached into his breast pocket and produced an envelope, thick, the colour of old cream, sealed with a smear of black wax. He laid it on the one clear inch of table. "A name," he said. "Yu-Fei wants it found. I told her the only courier in this city I'd trust with it works out of the Golden Empress." A pause. "I didn't tell her the courier hates me." "Smart. She'd have asked questions." Aurora didn't pick up the envelope. "And you came yourself. You don't deliver. You send people who deliver. You sent me, once, and look how that turned out." "I came because I owed you the courtesy of asking with my own mouth." His accent thickened, the way it did when the careful version of him thinned. "And because I am tired of London being a city you and I both live in while arranging never to occupy the same room." The honesty of it sat wrong with her, like a coin in the wrong currency. She turned away, busied her hands with the kettle so they'd have something to do that wasn't reaching. "You left," she said to the window. "You told me to." "You listened. That was the unforgivable part." She watched her own reflection over the dark of Brick Lane, watched his shape behind her, motionless. "Six weeks, Luc. Not a word. I thought you were dead. Then Eva sees you at some auction in Mayfair, very alive, very pressed, buying clocks." She laughed, and it came out raw. "Clocks." "They keep their value." Quiet. "And I thought — if I came near you, I would not have the discipline to stay away. So I stayed away from the start. It seemed the kinder arithmetic." "It wasn't kind. It was cowardly." She turned. He hadn't moved closer, and she hated that she noticed, hated the small disappointment of the distance. "You're a half-demon information broker who walks into rooms full of people who'd flay him for a debt, and you couldn't knock on a door." "This door," he said, "I have stood outside of four times. Tonight is the first I let myself ring." The kettle began its low building roar. Neither of them looked at it. "You should have rung the others," she said. "I know." She crossed the small space before she'd decided to. Stopped an arm's length from him, close enough now to see the faint stubble he never let show, the tired around the black eye that no glamour ever quite smoothed. He smelled of cedar and cold air and something underneath it, scorched, the thing in him that wasn't human. "I'm not your courier," she said. "No." "I'm not the woman on the gangway in Marseille, either. That was a performance." A muscle moved in his cheek. "Was it." "You tell me." Her voice dropped. "You're the one who watched me sleep on the ferry like I was a problem you couldn't price." He went very still. The kettle screamed. She reached past him without breaking his eyes, snapped off the gas, and the silence afterward rang. "That," Lucien said softly, "was not a performance." She should have stepped back. She should have picked up the cream envelope, named her fee, marched him to the three deadbolts, and let London keep them in separate rooms the way it had been doing so politely for six weeks. Instead she stayed exactly where she was, close enough to feel the heat coming off him, and asked the question she'd sworn in Marseille she'd never let herself ask. "Then why did you go?"
