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 over the door had been flickering for a week, and Silas kept meaning to fix it. Instead he watched it stutter against the rain-slicked window, throwing intermittent jade light across the maps on the wall, and told himself tomorrow. It was the slow hour, that dead stretch between the after-work crowd and the night people, when the Nest belonged mostly to him and the low hum of the cooler behind the bar. He was wiping down the brass tap handles when the door opened and let in a gust of November and a man he hadn't seen in nineteen years. For a moment Silas didn't recognize him. The man who came in stamping water off good shoes was heavier through the middle, his hair gone entirely white and cropped close to the skull, and he wore the kind of overcoat that cost more than Silas took in over a week. But then he turned his head to survey the room—that quick, lateral scan, taking in exits and sightlines without seeming to—and the years fell away like silt off a stone. "Marsh," Silas said. Daniel Marsh stopped. His eyes found Silas behind the bar and something complicated moved across his face, surprise overtaken almost immediately by something more guarded. Then he smiled, and the smile at least was the same. "Good God. They told me you'd opened a place. I didn't believe it." He came forward, and there was a hitch in his own stride now, Silas noticed—age, or something worse. "Silas Blackwood. Pouring drinks in Soho. I thought you'd have drunk yourself into a hedgerow somewhere by now." "The night's young." Silas reached for the good bottle, the Lagavulin he kept below the register for occasions he could no longer predict. "Sit down before you fall down. You always did look like a man about to keel over." Marsh laughed, but it cost him something. He lowered himself onto a stool with the care of a man whose body had become a series of negotiations. He set his hat on the bar—an actual hat, felt, with a brim—and Silas poured two measures and slid one across without asking. "You remembered," Marsh said, looking at the glass. "I remember everything. It's the curse of the trade." Silas raised his own. "To the ones who didn't make it home." It was an old toast between them, half a joke once, when they'd been young enough to believe the toast didn't apply to anyone they loved. Marsh's smile thinned. He drank anyway. "You've heard, then," he said. "Heard what?" "About Vance. About Prague." Marsh turned the glass in his fingers. The light caught a heavy ring there, gold, a family crest. The Marsh of nineteen years ago had worn nothing but a cheap watch and a permanent expression of skeptical amusement. "I thought that's why you said it. The toast." "I said it because I always say it." Silas felt the old wariness wake in him, the instinct that never fully slept. "What about Prague?" Marsh studied him a long moment, the way one reads a document for what's been left out. Then he seemed to decide something. He sat back. "Nothing. It's nothing. An old man's nerves." He gestured at the walls, the framed photographs, the maps gone amber with cigarette smoke that no longer happened here. "This is quite the shrine. You kept all of it." "It's décor. People like to feel they've wandered somewhere dangerous." Silas leaned against the back counter and folded his arms. His knee was speaking to him tonight, the way it always did when the weather turned, the souvenir Prague had left him with. "What do you want, Daniel?" The use of the Christian name landed between them like a stone in still water. Marsh's jaw worked. "Can't a man have a drink with someone who once carried him three kilometers with a bullet in his leg?" "That was your leg, not mine." "Was it." Marsh smiled faintly. "I've never been entirely sure whose leg it was, after a certain point. You were bleeding too. You never let on. That was always your trouble, Si. You'd rather die quietly than admit you needed a hand." Silas said nothing. The cooler hummed. Outside, the neon flickered green, green, dark, green. "You blamed me," Marsh said. Quieter now. The bravado had drained out of him along with the road dust of however many years. "After the safehouse. You never said it. You just stopped writing, stopped answering, and one day I heard you'd resigned and that was that. Nineteen years, Silas. I thought you'd died until last month." "I didn't blame you." Silas heard how flat it came out, how unconvincing. He tried again. "I blamed the decision. The decision was yours, but the decision was also—" He stopped. He had rehearsed this conversation, in the early years, in the bad hours, and now that the man sat in front of him the rehearsed words turned to ash. "There were nine people in that building, Daniel. I knew two of their names. I still know them." "So do I." Marsh's voice cracked, just slightly, the hairline fracture of a man who had spent decades not breaking. "You think you're the only one who carries it? You walked away. I stayed. I sat in those rooms and signed off on the reports and built a career on top of it, and every promotion was another floor I poured over the grave." He drank, hard, and set the glass down too sharply. "At least you got to be the man who left. I had to be the man who profited." Silas looked at his old friend—at the expensive coat that was a kind of armor, the ring that announced a station, the white hair, the careful body—and understood, finally, what had changed in him. It wasn't the weight or the age. It was that Marsh had spent nineteen years becoming someone large enough to hold the thing they'd done, and Silas had spent the same years trying to become small enough to slip out from under it. They had walked in opposite directions from the same wound, and arrived, somehow, in the same dim room with the same whisky between them. "I should have written back," Silas said. It was not absolution. It was the only true thing he had. Marsh nodded slowly, eyes wet and fixed on the maps, on a city neither of them had named aloud. "Yes," he said. "You should have." Then, after a long moment, he reached across the scarred wood and put his hand—the heavy ring, the loose old skin—over Silas's wrist. "Pour me another, you stubborn bastard. We've a great deal of silence to make up for, and not much time left to do it in." Silas poured. His hand, he noticed, was not quite steady. Outside, the neon held its green a moment longer than it had all week, as if deciding whether to let the dark have it. Then it flickered out, and the two men sat in the amber light of the lamps, drinking, while the rain came down on Soho and the night people did not yet arrive.
