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 came undone one by one. Three of them, each a separate complaint of metal, before the door cracked open on its chain. Rory looked out through the gap. The hallway light had burned out weeks ago, so all she got was a silhouette—broad shoulders, the line of a cane, the gleam of platinum hair catching what little light spilled from inside her flat. "You're a difficult woman to find," Lucien said. "I'm not lost. I just didn't want to be found." She didn't move to unlatch the chain. Behind her, Ptolemy wound between her ankles, indifferent to the visitor. "How'd you get past the curry house? They lock the stairwell." "I asked nicely." He tilted his head, and the amber eye caught the light, then the black one swallowed it. "And I tipped extravagantly. Are you going to let me in, or shall I conduct this through a four-inch opening like a confession?" "I haven't decided." "Then decide quickly. I've a feeling the gentleman downstairs is reconsidering his generosity." She held the door a moment longer. Three weeks since she'd last seen him, and her body still did the foolish thing it always did—the catch in her chest, the heat she resented. She'd told herself she was over it. She'd told herself a lot of things. The chain slid free. She stepped back. Lucien came in like he'd been invited, like the last conversation between them hadn't ended with her telling him to go to whatever realm would have him. He set the tip of his cane against the floorboards and surveyed Eva's flat—the towers of books, the scrolls unspooled across the table, the research notes pinned to every spare inch of wall. "Charming," he said. "I see you've taken up residence inside a library that lost a war." "It's Eva's. I'm watching it while she's away." "Watching it." He ran a gloved finger along the spine of a book, then withdrew it before she could tell him not to touch. "Is that what we're calling hiding now?" "What do you want, Lucien?" He turned. In the lamplight she could see him properly now—the charcoal suit, immaculate as always, but the collar slightly loose, a faint shadow beneath his eyes she wasn't used to seeing. Lucien Moreau did not look tired. It unsettled her more than she wanted to admit. "To talk," he said. "We talked. You remember how it ended." "Vividly. You called me a coward in two languages. I was impressed by the second one—your accent in French is appalling, but the sentiment carried." She crossed her arms. "You deserved it." "I did." He said it plainly, no performance, and that disarmed her more than any flourish could. "Which is why I'm here." Ptolemy leapt onto the table and settled among the scrolls, tail flicking. Rory used the moment to put distance between them, moving to the kitchenette, busying her hands with the kettle so she wouldn't have to look at him. "You don't apologise," she said. "That's the whole point of you. The man with all the information and none of the feeling. You told me yourself." "I tell people a great many things." "So which is the lie? The version where you don't care, or this one?" The kettle began its low hum. She heard the cane tap closer, a measured approach, and she kept her eyes on the rising steam. "You asked me to stay," he said. "That night. And I left because staying meant I had something to lose, and I have spent thirty-two years arranging my life so that I never do." A pause. "I told myself it was strategy. It was fear. I'm told there's a difference, though I struggle to locate it." She turned then. He was nearer than she'd expected, close enough that she had to look up, close enough to catch the trace of cedar and something darker beneath the cologne. His mismatched eyes held hers without their usual armour. "You don't get to do this," she said, and her voice came out softer than she meant. "Show up after weeks and—and be honest. It's not fair." "No. It isn't." He set the cane against the counter. The blade hidden inside it, the four languages, the careful charm—he laid all of it down with that single gesture. "Fairness was never something I could offer you. I'm not a good man, Aurora. I'm a useful one. But I find the distinction matters considerably less to me than it used to, and I cannot work out why, except that you're at the centre of it." The kettle clicked off. Neither of them moved toward it. "You hurt me," she said. "I know." "You left me standing in the rain on Greek Street like an idiot." "I know that too." His jaw tightened. "I walked to the end of the road and stood there for an hour, telling myself I'd made the sensible choice. I'm not in the habit of regret. It's a wasteful emotion. And yet." She laughed—short, disbelieving, wet at the edges. "And yet." He reached up, slow enough that she could have stepped away, and tucked a strand of black hair behind her ear. His glove brushed the scar on her wrist as his hand fell, and she felt the touch travel all the way up her arm. "Tell me to leave," he said, "and I'll go. I'll lock all three of your absurd deadbolts behind me and you'll never have to suffer my company again. But I won't pretend I didn't come here meaning to say this, and I won't pretend the saying of it was easy." Outside, a bus groaned past on Brick Lane. Ptolemy yawned, unbothered by the weight of the silence. Rory looked at him—the slight unevenness of his collar, the fatigue he hadn't bothered to hide, the open thing in his face that she'd never once seen there in all the months she'd known him. "You're a coward," she said. "You've established that." "In two languages." "Three, if you'd let me teach you the proper insult." She didn't smile. But she didn't step back either. "Stay," she said. "And if you leave this time, Lucien, I swear—" "I'm not leaving." He caught her hand, the one with the scar, and held it like it mattered. "That's rather the entire point I came here to make."
