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.

The green neon above the door buzzed its usual tired hymn, and Silas Blackwood, as was his habit on Tuesday evenings, stood behind the bar polishing a glass that did not need polishing. Rain had dragged a thin crowd into the Raven's Nest — two students arguing about Kierkegaard in the corner, a woman pretending to read a paperback while waiting for someone who would not come — and Silas found the quiet agreeable. He let his left leg rest against the lower shelf, easing the familiar ache in his knee, and watched the door the way a man watches weather: without expectation, but never without attention. He felt her before he saw her. Some old nerve at the base of his skull, the one MI6 had spent years teaching him to trust, tightened a degree. When the door opened, he did not look up immediately. He finished the glass. He set it on the rack. Then he raised his eyes, and the years folded in on themselves like a map handled too often. "Christ," he said. "Margaret." She had stopped just inside the threshold, rain beading on the shoulders of a coat too expensive for this street. Margaret Hollis. No — she'd remarried, hadn't she. He couldn't remember the name. Her hair had gone entirely white, cropped close to her skull in a way that suited her cheekbones but felt violent somehow, a declaration. She had been a red-haired woman when he'd known her, a woman whose laugh arrived before she did. The woman in the doorway did not look as though she laughed. She looked as though she had been emptied and refilled with something colder. "Silas." Her voice was the same. That, at least. "I wasn't sure you'd still be here." "I'm always here." "Yes." A small, careful smile. "That's rather the problem, isn't it." She came to the bar and sat two stools from the corner, the way they had been trained to sit, so she could see the door without appearing to. He poured her a whisky without asking. Talisker, neat, a splash of water. Her eyebrows lifted. "You remember." "I remember everything," he said, and heard how it came out — heavier than he meant, closer to confession than fact. He set the glass in front of her. His signet ring clicked once against the wood. "How did you find me?" "I didn't. I was at a dinner on Dean Street. I walked past your sign three times before I worked up the nerve." She lifted the glass, considered it. "You know, I once told Henry you were dead." "Henry's the husband?" "Henry was the husband. He died in March." "I'm sorry." "Don't be. He was very kind and I failed him beautifully for twenty-two years." She drank. Closed her eyes briefly. "God. You still buy the good stuff." "I still drink the good stuff. The customers get what they deserve." She laughed then — a single soft note, nothing like the laugh he remembered, but enough. Enough that for a moment he could see the woman who had crouched with him behind a Škoda in a Prague alley in February of 1994, her breath ghosting white, her hand on his wrist to keep him still. The crescent of a streetlamp above them. The weight of a decision neither of them had yet made. "You're limping," she said. "I've been limping a long time." "Yes. I know." She turned the glass a quarter-turn on the bar, and he watched her watch it. "I've thought about that night, Silas. More than I should have. I told myself for years that we did what we had to do. And then I stopped telling myself that, because it wasn't helping." "What helps?" "Nothing." She looked up. Her eyes were grey and tired and unflinching. "That's what I came to tell you, I think. In case you were still trying to find the thing that helps. Nothing does. You just get older, and the guilt becomes a kind of furniture. You stop bumping into it." Silas set the towel down. He was aware of the student in the corner gesturing too broadly, of the woman with the paperback paying her tab and leaving, of the rain picking up against the window. He was aware of his own hand on the bar, older than he remembered hands being, the signet dulled along its ridges. "I wrote you," he said. "After. Twice." "I know." "You didn't answer." "I know." She drank again, and the glass trembled very slightly, and she set it down with great care. "I couldn't, Si. If I'd answered I would have come back. And if I'd come back I would have blamed you, and you would have let me, and we would have made each other very unhappy for a very long time. I chose Henry instead. It was cowardice. I know what it was." "It was survival." "Don't be generous. You were never generous with yourself; don't start being generous with me." He almost smiled. There was a particular pain in being known — truly known, after years of being merely observed — and he had not felt it in so long that it came on him like weather, unbidden and total. He poured himself a finger of the same whisky and lifted the glass a fraction of an inch toward her. She matched it. They drank without speaking. Upstairs, a floorboard creaked: Aurora, home from a delivery run, moving across the flat above. Margaret glanced at the ceiling. "You have someone up there?" "A tenant. A girl from Cardiff. She reminds me of who I might have been, if I'd been braver earlier." "And who's that?" "Someone who ran toward the thing instead of away from it." He looked at Margaret, at the white hair and the thin mouth and the grey eyes that had once undone him in a language he no longer spoke. "I don't know if I ever told you. I meant to. In the letters, I was going to." "Tell me now." He opened his mouth. The neon buzzed. The rain found the gutter. And he found, to his quiet astonishment, that after thirty years he still did not have the words — only the shape of them, worn smooth as a stone in a pocket, a thing carried so long it had become indistinguishable from the hand that carried it. "Another time," he said. She nodded, as though she had expected this, as though it were, in its way, an answer. "Another time," she agreed, and did not finish her drink.
