You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The green neon bled through the rain-streaked window, painting the bar in a sickly wash that suited Silas just fine. He'd kept the lights low on purpose. Tuesday nights brought the regulars who preferred their faces unexamined, and he had nothing to prove to anyone who walked through that door. Until the door opened, and a man he'd buried twenty years ago walked through it. "Christ," Silas said. The cloth in his hand stilled against the glass. "Daniel Voss." The man stamped rain from his shoes, shook out an umbrella that cost more than Silas made in a slow week. He'd gone soft in the way prosperous men went soft, the edges of him rounded and comfortable, his coat the colour of money kept quiet. But the eyes were the same. They found Silas behind the bar and went very still. "They told me you were dead," Daniel said. "They told a lot of people that. It was useful at the time." "Useful." Daniel laughed without anything behind it and crossed the room. He moved like a man unaccustomed to entering spaces uninvited, hovering at the bar's edge until Silas tipped his head at a stool. "You let me put flowers on a grave, Si. In Prague. There was a stone with your name spelled wrong." "Blackwood with a 'u'. I always hated that." Silas set a glass down and reached for the bottle on the high shelf, the one he didn't pour for paying customers. "Sit down before you fall down. You look like you've seen something worse than a ghost." "I've seen a man I grieved pulling pints in Soho." Daniel sat. He laid his umbrella across the bar like an offering, then thought better of it and hung it from the stool's edge. "Twenty years. I left the service. Did you know that? I went into law. Corporate, contracts, the kind of thing where nobody dies because you forgot a detail." "I heard." Silas poured two fingers, slid one across. "I keep ears in places. You did well. House in Surrey, two girls at university. The younger one rows." The colour went out of Daniel's face. "You've watched me." "I watch everyone I've loved." Silas said it the way he might have read a weather report, but his hand curled tighter around his own glass. "It's a habit. It kept me alive when better men weren't. I'm sorry it frightens you." "It doesn't frighten me." Daniel drank. He grimaced at the burn of it, the way he never had at twenty-six when they'd thrown back worse in worse places. "It just makes me feel like a fool. All these years I built something, and you were sitting in the audience taking notes." The bar held its breath between them. Rain ticked against the window. Somewhere in the back a pipe knocked, the building settling into its arthritis the way Silas settled into his bad knee on cold nights. "You came in here by accident," Silas said. It wasn't a question. "I had a meeting fall through. A client. I was walking, I saw the green sign." Daniel turned the glass in a slow circle on the wood. "I thought I'd get out of the rain. I didn't think." He looked up. "Is that funny to you? After everything, after all the tradecraft, I found you because I was bored and wet." "It's the only way anyone finds anything that matters." Silas leaned against the back counter, easing weight off the left leg. "We spent careers building elaborate ways to meet, dead drops and brush passes and signals in newspaper adverts. And here you are. Wet. Bored." He lifted his glass an inch. "Hello, Daniel." "Hello." The word cracked in the middle. They drank. Outside, a couple ran past under a shared coat, laughing, their voices smearing through the glass and gone. "You should have told me," Daniel said finally. "Prague. You should have got word to me. One line. I'd have kept it. You know I'd have kept it." "That's exactly why I didn't." Silas set his glass down. The signet ring clicked against it. "If you'd known I was alive, you'd have carried it. Every dinner, every Christmas, every time someone mentioned my name and watched your face. You'd have lied for me for two decades and it would have hollowed you out one quiet supper at a time. I've seen what that does. I did you a kindness by being dead." "You did yourself a kindness. Don't dress it up." Daniel's voice rose and then he caught it, pressed it flat. "We were friends. You decided I couldn't be trusted with the truth, so you took it. You always did that. Decided what people could hold." "And I was usually right." "You were always right. That was the worst of it." Daniel pushed the glass away. His hand trembled, the old man's tremor that comes early to people who've been afraid for a living. "Do you know what I wanted to tell you, at that grave? I'd brought the words and there was nobody to give them to. I wanted to say I'd forgiven you for Brno. For leaving Kessler behind. I'd carried it ugly for two years and I came to set it down at your stone and you weren't even under it." Silas didn't move. The neon hummed. When he spoke his voice had dropped to something worn smooth. "I left Kessler because the alternative was losing both of you. There wasn't time to explain it then either." "I know that now. I knew it then." Daniel pressed the heel of his hand to one eye, briefly, then took it away. "That's not the point. The point is I never got to say it. You took even that. My forgiveness was the one thing I had that was mine to give, and you made it useless." The clock above the bottles read half eleven. Silas reached out and, after a moment that cost him something visible, laid his weathered hand over Daniel's on the bar. "Say it now," he said. "I'm not under the stone. Say it now."
