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 clunk that echoed down the stairwell, and Rory pulled the door open expecting Eva, expecting the curry house owner come to complain about the noise, expecting anyone but the man who stood on the landing with rain darkening the shoulders of his charcoal suit. "You've changed the locks," Lucien said. "You've changed nothing." She held the door at the width of her own body, one bare foot braced against the bottom of it. "Still showing up where you're not wanted." "That presumes I know where I'm wanted. A rare commodity, that information." He tilted his head, and the landing light caught the strange split of his eyes — amber on the left, black as a drowned well on the right. "May I come in, or shall we conduct this on the stairs where Mrs Achterberg downstairs can take notes?" Ptolemy wound between her ankles, traitorous, and slipped out onto the landing to rub against Lucien's trouser leg. Rory watched the cat betray her and felt something tighten under her ribs. "Eva's not here." "I didn't come for Eva." The rain ticked against the small window behind him. She thought about the last time she'd seen him — the warehouse off Limehouse, the blood on the floor that hadn't been hers, the way he'd turned and walked into the dark without a backward glance after she'd asked him, plainly, to stay. Three months of nothing. Three months of telling herself she'd imagined the heat of his hand at the small of her back. She stepped aside. He came in the way he did everything — without hurry, the ivory handle of his cane tapping once on the threshold. The flat closed around him, all of Eva's books and scrolls and the smell of old paper and the curry oil that seeped up through the floorboards. He looked too clean for it. He always had. "Drink?" she said, only because her hands needed something. "If you're offering it instead of throwing it." "Don't tempt me." She poured two fingers of Eva's whisky into the one clean glass and kept the bottle for herself. He didn't sit. He stood in the middle of the cramped room and turned, taking the measure of the chaos, the maps pinned to the wall, the research notes weighted down with chipped mugs. "You've been busy," he said. "Someone had to be. You weren't answering." "No." He set the cane against the table. "I wasn't." The honesty of it landed worse than an excuse would have. She drank straight from the bottle. "Three months, Lucien." "Ninety-one days." "You counted." "I count everything. It's a professional habit." He picked up one of Eva's scrolls, glanced at it, set it down with the care of a man handling something that might wake. "You asked me to stay. In the warehouse." "I remember what I asked." "I want you to understand why I didn't." "I understand perfectly." She put the bottle down hard enough that the whisky climbed the glass walls. "You're a fixer. You fix, you take your fee, you leave. I knew what you were before I let you—" She stopped. The word hung there, unfinished, and she hated that her mouth had betrayed her the way the cat had. "Before you let me," he repeated, soft. "Don't." "You think I left because the job ended." He crossed the small distance between them, and the room had never felt smaller — every book seemed to lean in. "I left because if I had stayed one more minute in that warehouse with you bleeding from a wound you took for me, I'd have done something I couldn't undo. I've spent thirty-two years keeping a careful ledger of what I owe and what I'm owed. You don't fit in the columns, Aurora." She looked up at him. The amber eye held the lamplight; the black one held nothing at all, and she'd learned long ago that the black one was the honest one. "That's not a reason. That's an excuse dressed up in French tailoring." The corner of his mouth moved — not quite a smile. "You wound me." "I'd like to. Properly, this time." "I came back," he said. "Three months late." "Ninety-one days late, and through a thunderstorm, having paid a man a great deal of money to tell me which of Eva's three hiding places you'd actually be in." He reached out, slow enough that she could have stepped back, and touched the inside of her left wrist where the small crescent scar sat pale against her skin. "I don't do this. Cross London for a person. I've built an entire reputation on never being the one who crosses London." She didn't pull her hand away. That was the trouble. Her body had made a decision her mind hadn't signed off on. "Then why," she said, and her voice came out lower than she wanted, "are you standing in my dead friend's flat, getting rain on her floorboards?" "Because the ledger doesn't balance without you in it." His thumb moved over the scar, once. "And I'm tired of pretending the columns add up." The whisky burned in her chest, or maybe it wasn't the whisky. She thought of every clever, cruel thing she'd rehearsed for this exact moment in the long dark hours when she couldn't sleep — the speeches, the slammed door, the dignity of indifference. None of them came. The only thing in her mouth was the truth, and she'd never been good at swallowing it. "You don't get to do this," she said. "You don't get to vanish and then walk back in and touch my wrist like you've got the right." "No," he agreed. "I don't." "So why are you?" "Because you haven't told me to stop." She should have. The word sat ready behind her teeth. Stop. Go. Leave the way you're so very good at leaving. Instead she stood there with his thumb against her pulse and the rain at the window and Ptolemy weaving figure-eights around both their legs as though stitching them together. "You hurt me," she said. "I know." "That's not an apology." "No." He let go of her wrist, but only to bring his hand up, knuckles grazing the line of her jaw, a question more than a claim. "I'm not certain I know how to make one. But I came back. That has to count for something in your ledger, if not mine." She caught his hand. Held it still against her cheek. Looked at the two mismatched eyes and decided, recklessly, to answer the honest one. "It counts," she said. "It doesn't forgive. But it counts."
