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 hummed its tired pulse above the door, throwing a sickly wash across the rain-slick pavement, and Silas had nearly locked up for the night when the bell over the door gave its small apology and a man stepped in out of the wet. He knew the walk before he knew the face. Twenty-six years had a way of changing a man's features—softening the jaw, hollowing the cheeks, salting the hair—but it could never quite reach the gait. This one came in with the careful economy of someone who had spent his life entering rooms he wasn't certain he'd be allowed to leave. Silas set down the glass he'd been polishing. "We're closed," he said, because it was true, and because some old reflex wanted to test the water before he committed to it. The man stopped beneath the photographs, beneath the framed map of Central Europe that Silas had hung crooked years ago and never bothered to straighten. He pushed back the hood of his coat. Rain dripped from the hem onto the floorboards. "You always did close early, Si. Even in Vienna. Remember the place near the Naschmarkt? You'd have the chairs up before the last drinkers were through their glasses." Silas felt the years drop away from under him like a stair tread giving out. "Daniel." "It's Marsh now, mostly. Has been for a long while." He smiled, and the smile was the thing that had changed least and most all at once. The shape of it was the same. The warmth behind it had gone somewhere Silas couldn't follow. "But Daniel's fine. From you." For a moment neither of them moved. The bar held its breath around them—the dim amber lamps, the old maps with their borders that no longer existed, the smell of spilled whisky soaked so deep into the wood it had become a kind of foundation. Silas had built this place to be a fortress disguised as a refuge. He had not expected the past to simply walk through the front door and shake the rain from its coat. "Sit," he said. "I'll pour." Daniel took the stool at the end of the bar, the one nearest the bookshelf, and Silas wondered if he knew what lay behind it, if some part of the old training had read the seams in the wood and understood. He probably did. Men like them never fully retired; they only changed the labels on their files. Silas poured two measures of the Lagavulin he kept for himself and slid one across. Daniel turned the glass in his fingers without drinking. The lamplight caught the back of his hand—a tremor there, fine and constant, the kind that no longer announced itself but simply lived in a body now. "You look well," Daniel said. "I look old." "That's the same thing, at our age. Looking well is just being upright and unsurprised." He glanced down at Silas's leg, at the way he favored it standing. "Prague?" "Prague," Silas agreed. The word sat between them like a third drinker neither had invited. Prague was the hinge on which both their lives had turned, though only one of them had walked out of it whole, and Silas had never been entirely sure which one that was. He drank. The peat smoke filled his mouth and he let it. "I read you'd opened a bar," Daniel said. "Years ago. I didn't believe it. Silas Blackwood, the man who once told me sentiment was a leak in the hull—pulling pints in Soho." He looked around at the walls, the photographs, the faces caught mid-laugh in cities that had since fallen or been rebuilt. "And then I came in and saw the walls and I thought, no. He hasn't gone soft at all. He's just changed the cover." "Everyone needs somewhere to drink," Silas said. "Even ghosts." "Is that what we are?" "It's what you came here looking for, I think. Or you'd have called ahead." Daniel laughed, and it turned into a cough, and he covered it with the back of the trembling hand. When he lowered it again something in his expression had gone quiet and serious. "I tried to call ahead. Years ago. Eighty-nine, ninety. After the wall came down and everything we'd done in the dark suddenly looked—" he searched for the word— "pointless. I wanted to ask you whether it had been worth it. Whether the boy was worth it." The boy. Silas set his glass down very carefully, as though it might detonate. "Don't," he said. "I've spent twenty-six years not saying it. I think I've earned the saying of it once." Daniel's voice did not rise. It stayed soft, almost gentle, and that was worse. "We left him there, Si. We made a calculation and the calculation said one asset for a network, and the network was the thing, the network was always the thing, and the boy was nineteen and he trusted me because I'd told him to." "We didn't have time—" "No. We didn't. I know all the reasons. I wrote half of them in the report." He finally drank, a small sip, and grimaced not at the whisky but at the memory. "I'm not here to indict you. God knows I was the one holding the radio. I'm here because I'm dying, and a dying man gets sentimental, which you'd have despised in me once, and there are only two people left alive who know what happened in that flat off Wenceslas Square, and I didn't want to be the last one carrying it." The neon outside buzzed and dimmed and steadied. Silas looked at the man before him and tried to find, beneath the ruined face and the shaking hand, the young officer who had quoted poetry in three languages and believed, genuinely believed, that they were the thin and necessary line. Time had not been kind. But then time was never kind; it was only thorough. "His name was Tomáš," Silas said at last. The name came out rusted, unused. "I never let myself say it. I thought if I didn't say it, it wouldn't have weight." "And did it work?" "No." Silas refilled both glasses. His own hand, he noticed, was steady—the body's last small lie. "It's heavier for the silence. Everything is." Daniel nodded slowly, as if this confirmed something he had crossed a city in the rain to hear. Outside, a taxi hissed past on the wet street and was gone. The two of them sat in the amber light beneath the borders that no longer existed, two old men and the boy between them, and for a long while neither felt the need to say anything more at all.
