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 door opened, and it was not Eva. Rory knew it the way she knew a pothole on the Commercial Road before her front wheel found it: a half-second of warning, too late to swerve. She had undone all three deadbolts because Eva always forgot her keys, and because nobody else knocked like that, two quick raps and a pause, as if apologising for the third. Except someone else did, apparently. Lucien Moreau stood on the narrow landing with rain beading on the shoulders of his charcoal suit. His platinum hair, usually slicked back with ruthless precision, had come loose at the temple, one pale strand stuck to his forehead. He held the ivory-handled cane in his left hand. His right hand was wrapped in a white handkerchief that was not entirely white anymore. The smell of cumin and frying onions drifted up the stairwell from the curry house below. Somewhere behind her, Ptolemy thumped down from a stack of books and came to investigate. "Aurora," he said. Not *Rory*. He had only ever called her Rory once, and she had spent six weeks trying to forget how it sounded in his mouth. "Eva's in Edinburgh," she said. "I know." "Then you've come to the wrong flat." "I went to yours first." His amber eye caught the light from the hall bulb. The black one gave nothing back, it never did. "Silas told me where to find you. Eventually. I think he enjoyed making me wait." "Silas has good instincts." She kept one hand on the door. Her voice came out level, which surprised her, because her pulse had not been level since the latch clicked. "What happened to your hand?" He glanced down at it as if he'd forgotten. "A disagreement." "With?" "Someone who asked about you." That landed somewhere under her ribs. Ptolemy wound between her ankles, tail high, and then, the traitor, stepped over the threshold to sniff the hem of Lucien's trousers. "You should come in," she said, "before the cat decides he likes you." "Is that likely?" "He likes everyone. He's got no judgement at all." Something moved at the corner of Lucien's mouth. Not quite a smile. He stepped past her into the flat, and she shot the deadbolts home behind him, one, two, three, because her hands needed something to do. Eva's flat was not built for two people who were trying not to touch. Every surface held something: books stacked spine-out on the floor, scrolls weighted open with mugs, index cards tacked to the wall in constellations only Eva understood. Lucien had to angle his shoulders to get between the armchair and a tower of Victorian occult journals. He stood in the middle of the tiny sitting room like an expensive watch dropped into a junk drawer. "Sit," Rory said. "Kitchen chair. Don't touch the notes on the table or Eva will kill us both." He sat. She filled the kettle, because that was what you did, because her mother had done it in every crisis of her childhood, and then she dug the first-aid kit out from under the sink where Eva kept it next to a jar of something labelled *DO NOT OPEN — BELLADONNA (PROBABLY)*. When she turned back, he was watching her. "Give me your hand." "It's not serious." "You've bled through a silk handkerchief. Give me your hand, Lucien." He held it out. She unwound the cloth. The cut ran across his palm, clean and shallow, the kind of wound you got from catching a blade rather than being caught by one. She'd seen worse on the kitchen staff at the Golden Empress. It still made her stomach tighten. "You caught it," she said. "It was that or my throat. I have always been fond of my throat." She tipped antiseptic onto a pad and pressed it to his palm harder than strictly necessary. He hissed through his teeth, a word in French she didn't know but could guess. "Who was he?" "A collector. He works for someone in Southwark who has heard there is a woman in Whitechapel with a demon's name written on her soul." His voice was even, the voice he used for business. "He wanted an address." "And you didn't give it to him." "No." "That makes a change." The kettle began to rattle on its base. Neither of them moved toward it. Lucien's hand was very still in hers. "I deserved that." "You did." She started winding gauze around his palm. Her own wrist turned as she worked, and she saw his gaze drop to the small crescent scar there, the one he'd traced with his thumb on the night in question, asking how she got it. *Fell off a wall when I was eight*, she'd told him. *Showing off for Eva.* He'd laughed, the real laugh, the one he didn't use in front of clients. Two days later he'd sold her name. "You told Castellane who I was," she said, not looking up. "You told him I was the one who broke the seal. You didn't ask me. You didn't warn me. I found out from a man with a knife in the car park behind Silas', and when I came to find you, you'd left London." "I told Castellane," Lucien said quietly, "because he already knew there was someone. He was going to take the city apart looking. I gave him a name and a story that made you useless to him. A courier who'd stumbled into something. Harmless. Not worth the effort." He paused. "It worked. He stopped looking." "And the man in the car park?" "Was not Castellane's. That was my mistake. I did not account for everyone who was listening." His jaw tightened. "I have been accounting for them since." She tied off the gauze. Her fingers stayed on the knot a moment longer than they needed to. "That's where you went," she said. "For six weeks." "Yes." "You could have called." "I could have." He looked at their hands. "I wrote you a letter in Lisbon. Four pages. I burned it in Prague because it was cowardly. The second one I wrote in Vienna was worse." "What did it say?" "That I was sorry. That I had done it to keep you alive, and that I would do it again." He lifted his eyes to hers. "That second part was the problem. I didn't think you would forgive a man who meant it." The kettle clicked off. In the silence she could hear the rain on the window, the muffled clatter of the kitchen downstairs, Ptolemy crunching biscuits in the corner. Rory thought about Evan. She tried not to, mostly, but it came anyway: the way he'd rearranged her life around what he decided was good for her, the careful reasonable voice, *I'm only doing this because I love you*. How long it had taken her to see the walls for what they were. "Here's the thing," she said. "I don't need you to protect me by making choices I don't know about. I've had that. I left Cardiff to get away from that. If you'd come to me, if you'd said, *Rory, Castellane's hunting, here's my plan*, I might have hated it. I might have agreed anyway. But it would have been mine." He was quiet for a long moment. "You're right." She hadn't expected him to say it so simply. She'd prepared for the fixer, for elegant evasions in four languages. Not this. "I'm not used to it," he said. "Asking. In my work, the person who asks permission is the person who ends up in the river." He turned his bandaged hand over in hers so that his fingertips rested against the inside of her wrist, right over the scar. "But you are not my work. I should have understood that sooner. I think I did understand it. That's what frightened me." Her breath went shallow. "Lucien." "You asked what I left unsaid." His thumb moved, barely, along the curve of the old scar. "I left most of it. I left the part where I stood outside Silas' bar at two in the morning the night before I went, looking at your window, and didn't knock. I left the part where every city I went to, I found myself wondering what you'd think of it. You would hate Vienna, by the way. Far too tidy." A laugh escaped her before she could stop it, small and startled. "I'd love Lisbon." "You would. The hills would ruin your bicycle." "Everything ruins my bicycle." His mouth curved properly now, and it changed his whole face, took ten years and a great deal of armour off it. She realised she'd moved closer; or he had; or the flat was simply too small for distance. The rain ran down the window behind him in silver threads. His knee was against hers under Eva's table. "So now I'm asking," he said, and his voice had dropped to something rough and unguarded. "Southwark knows there's someone. They don't know where. I can keep it that way, but not alone, and not without you knowing every piece of it. I would like to stay tonight. On the sofa, if you prefer. Under the table with the cat, if necessary." A breath. "And I would like, when this is over, to take you to Lisbon. If you'll let me. That part is not strategy." Rory looked at him: the loose strand of hair, the bandage she'd tied, the mismatched eyes holding hers without any of their usual distance. "The sofa's covered in Eva's manuscripts," she said. "Then I'll move them. Carefully." "She'll know." "She will forgive me eventually. People sometimes do." She turned her hand in his, laced her fingers through his uninjured ones, and felt him go very still, as if he were afraid to breathe and break it. "Ask me about Lisbon again," she said, "when nobody's trying to kill me." "That may be some time." "Then you'd better stay close enough to ask." He lifted her hand, slowly, giving her every chance to pull away, and pressed his lips to the crescent scar on her wrist. His mouth was warm, and he held it there for one long heartbeat before he let go. Behind them, Ptolemy leapt onto the table and sat squarely on Eva's research notes, as if to remind them both whose flat it was.
