You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

Write the scene from the moment the door opens. Use the codex entries above as your world reference for characters and setting. Only include the prose of the scene without any markdown or commentary.

The three deadbolts gave one after another, metal sliding against metal, before Aurora even thought to ask who it was. That was the mistake she'd been trained out of, the one Eva nagged her about — but it was nearly midnight, and she'd been expecting the curry house downstairs to send up the last of the day's unsold naan, the way they sometimes did when Mr. Rahman took pity on her. She opened the door on a sliver of yellow stairwell light, and there he was. Lucien Moreau filled the narrow landing the way he filled any space — not by size, though he had a few inches on her, but by sheer composure, as if the building itself had rearranged to make room. His charcoal suit was immaculate despite the rain that had started an hour ago, the shoulders dark with damp, the ivory handle of his cane catching the bare bulb above. His platinum hair was slicked back, a single strand fallen loose against his temple. One amber eye and one of perfect black regarded her with an expression she couldn't read, and she hated that she still tried. "Rory," he said. The accent did what it always did to her name, softened the hard edges into something almost tender. She gripped the door. "No," she said. "I haven't asked you anything yet." "I know you, Lucien. The answer's going to be no." A faint curve at the corner of his mouth — not quite a smile. Behind her, Ptolemy slunk along the back of the sofa, tail flicking, taking in the visitor with the indifferent suspicion of a cat who had seen worse come through these doors. "You're going to leave me standing in the rain," Lucien said. "After Lisbon." "Especially after Lisbon." But she didn't close the door. That was the trouble. She'd rehearsed this moment a hundred times in the four months since she'd walked out of that hotel room with her heart in pieces and her dignity barely stitched together, and in every version she'd slammed the door so hard the deadbolts rattled. In none of them had she stood here in an oversized jumper and bare feet, her wet hair from the shower still cold against her neck, simply looking at him. "Five minutes," he said. "Then I'll go. You have my word." "Your word." She laughed, and it came out uglier than she meant. "Do you know what your word is worth?" Something flickered across his face then, quick as a struck match. For all his polish, she'd learned to catch those flickers — they were the only honest thing about him. "I know exactly what it's worth," he said quietly. "Which is why I'm offering it now." She should have shut the door. Instead she stepped back, and he took it for the invitation it half was, moving past her into the cramped warmth of Eva's flat. He had to angle his shoulders to avoid a tower of Eva's research — leather-bound volumes stacked waist-high, scrolls jutting like the bones of some half-buried thing, sticky notes in three colors of ink crawling up the wall. He glanced at it all, took it in the way he took in everything, filing it away. She watched him decide not to comment. She closed the door but left the deadbolts open. A small rebellion, that. *I am not keeping you. You are not staying.* "Eva's not here," she said. "If that's what this is. Information. Whatever you're—" "It isn't." He turned to face her. The flat was so small that turning brought him close, close enough that she caught the rain-and-cedar smell of him, and her body betrayed her with a memory so vivid it stole the breath from her: his hand at the small of her back on a balcony over the Tagus, the lights of the bridge below, the way he'd said her real name like it was a secret he'd kill to keep. Then morning, and the empty bed, and the note that wasn't even a note, just a name and a number and the words *trust no one with this.* "You left," she said. The words were out before she could stop them, and she despised how raw they sounded. "You got what you needed and you left me there. With Vasco's people three floors down, asking the concierge for the English girl." "I know." "You don't get to just—" She pressed her lips together. "You don't get to *know.* That's not an answer." "It's not meant to be one." He set the cane against the cluttered table, deliberate, and the small surrender of it — putting down the only weapon he carried openly — undid something in her chest. "I left because if I'd stayed they'd have had us both. I left a name because it was the only door I could see out for you. And I have spent four months telling myself it was the right call." A pause. "I came tonight because I've stopped believing it." The rain ticked against the window. Downstairs someone laughed, a door banged, the ordinary noise of a Brick Lane night carrying on as if the floor of her stomach hadn't just dropped away. "You're a fixer," she said, unsteady. "You don't get to have regrets. They're inconvenient." "They are extraordinarily inconvenient." He took a half step closer, and she didn't retreat, and that was its own kind of confession. "Do you imagine I make a habit of this? Crossing a city at midnight to stand in a flat that smells of cumin and tell a woman I was wrong?" "I don't know what you make a habit of, Lucien. That was rather the problem." His jaw tightened. The amber eye held hers; the black one, depthless, gave nothing. "Ask me," he said. "Whatever you've wanted to ask for four months. I'll answer it. Truthfully. That's what I came to give you. Not information you can sell. The other thing." "What other thing?" "The truth about why I didn't take you with me when every part of me wanted to." The air had gone thin. Ptolemy hopped down from the sofa and wound between Lucien's polished shoes, utterly unbothered, and Aurora found she couldn't look away from the man's face — from the loose strand of hair, the rain still beading at his collar, the careful stillness of someone braced for her to throw him out. She thought of Lisbon. She thought of every clever thing she'd planned to say. None of them would come. "Five minutes," she heard herself say. "You said five minutes." "I did." "Then talk fast." She crossed her arms, the crescent scar on her wrist pale in the lamplight. "Because I'm still deciding whether to scream for Mr. Rahman." For the first time, Lucien smiled — the real one, the rare one, the one she'd been stupid enough to fall for over a stolen bottle of wine. "Then I'd best be worth the silence," he said, and began to talk.
