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 third deadbolt was the stubborn one. It always stuck in the cold, and tonight the rain had crept in under the windowsill and made the whole flat smell of wet brick and old paper. Aurora had her thumb pressed against the chain, the door cracked just enough to peer through, when she saw the cane. Ivory handle. Caught the hallway light like something carved from bone. She knew before she lifted her gaze to his face. Of course she did. There was only one man in London who carried a blade dressed up as elegance, who stood in a stranger's stairwell at half past ten on a Tuesday looking as though he'd materialized from a tailor's catalogue and not the rain hammering the curry house below. "Aurora." Lucien Moreau said her name the way he said everything — unhurried, deliberate, as if he had all the time in the world and intended to spend it watching her squirm. "No," she said, and started to shut the door. He didn't move to stop it. That was the worst part. He simply waited, the amber eye and the black one fixed on her through the narrowing gap, and let the silence do the work he was too refined to do himself. She held the door at four inches. Ptolemy threaded between her ankles, tail high, traitorously curious. "How did you find me?" "You're staying with Eva." A faint shrug rolled through his shoulders. The charcoal of his suit was darker at the shoulders, soaked through. "It wasn't difficult. You always run to the same places." "I don't run." "No?" The corner of his mouth moved — not a smile, just the suggestion of one, the ghost of every conversation they'd ever ended badly. "Then perhaps you'll let me in. I'm getting wet, and you know how I feel about my suits." She should have shut the door. She had told herself, in the eleven weeks since Marseille — no, she would not think about Marseille, not the harbor lights, not his hand at the small of her back, not the thing he'd said and then unsaid before dawn — she had told herself that if she ever saw him again she would shut the door and feel nothing. She undid the chain. The deadbolt scraped. She stepped back, and Lucien came in out of the rain like he'd been invited, like he belonged, ducking his head under the low lintel and bringing the smell of him with him — cold air and cedar and something underneath it that wasn't quite human, that her body remembered before her mind caught up. "Charming," he said, surveying the wreckage of Eva's research. Scrolls slid off the sofa. A teetering ziggurat of library books occupied the single armchair. "She still hoards like a dragon." "You can't stay." "I'm aware." He set the cane against the bookshelf with a soft click and turned to face her, and for a moment the polish slipped. Just a moment. She saw the tiredness under his eyes, the wet hair losing its careful slick, a man who'd come a long way in foul weather to stand in a cramped flat that smelled of someone else's dinner. "Something's coming for you, Aurora. I came to warn you. That's all." Her stomach dropped, but she crossed her arms over it, kept her voice flat. "You came all the way from wherever you've been hiding to tell me that in person? You have phones. You have people. You have a hundred ways to pass a message that don't involve standing in Eva's hallway dripping on her carpet." "I do." "So why?" He held her gaze. The black eye gave away nothing — it never had — but the amber one had always been the tell, and right now it was searching her face the way a man reads a letter he already knows by heart and hopes the words have changed. "Because the last time I sent a message instead of coming myself," he said quietly, "you nearly died believing I didn't care whether you did." The flat went very still. Even the rain seemed to hush. "Don't," she said. "You asked." "I didn't ask for that." Her arms tightened. She could feel the old scar at her wrist, the small crescent, pressing against her ribs, and she hated that she'd gone to it, hated that her body knew where to retreat. "You left, Luc. I woke up and you were gone and there was a train ticket on the pillow like I was — like I was a job you'd finished." "I left to keep you out of it." "You left because it was easier." The words landed. She watched them land. Something flickered across his face, quick as a struck match, and then he had it under control again, the fixer's mask sliding back into place, smooth and pleasant and unbearable. "Perhaps both can be true," he said. She laughed, short and joyless, and turned away because she couldn't look at him and stay angry, and staying angry was the only thing keeping her upright. She busied herself with the kettle. Filled it. Set it down without switching it on. Realized she'd done nothing useful and gripped the edge of the counter instead. "What's coming for me," she said to the window, to her own reflection floating on the rain-streaked glass with his shape behind it. "A man who knows one of your names." He said it gently, and the gentleness was worse than anything. "Not Rory. Not Aurora. The other one. The one you don't tell people." Her knuckles went white on the counter. "Malphora," he said. The name moved through the small room like a draught under a door. She felt it touch the back of her neck. She had not heard it spoken aloud in years — had spent years making certain no one alive could speak it — and now it was here, in Eva's flat, in his mouth, and the floor of her careful new life tilted under her feet. She made herself breathe. She made herself turn around. He was closer than she'd realized. Close enough that she could see the rain still beaded on his lashes, close enough to see that the unflappable Lucien Moreau was, for once, not entirely sure of his ground. "How long have you known," she whispered. "Long enough to be afraid for you." His voice dropped, lost its lacquer. "And I do not enjoy being afraid, Aurora. It's an unfamiliar habit. I find I dislike it intensely." She should have stepped back. The kettle, the counter, the three deadbolts, all of it built to keep the world out — and she'd opened the door anyway, and here he stood, dripping and dangerous and the only person who had ever made her feel both safe and entirely unmoored at once. "You don't get to do this," she said, and her voice cracked right down the middle. "You don't get to walk back in and say my name like it means something to you." "It means," he said, very low, "a great deal more than I intended it to." Ptolemy wound between them, oblivious, purring. Outside, the rain came down on Brick Lane, and neither of them moved, and the small space between them filled with everything they had spent eleven weeks not saying.
