Model input
User/Human
You are an expert novel writer in the cozy mystery genre. Write a scene of about 200 words, with dialogue between two characters. The dialogue should be unattributed, meaning the speaker is not explicitly mentioned. The scene should be set in a small town bakery. Only return the story, nothing else.

The bell over the door had stopped ringing an hour ago, and the last cinnamon twists sat cooling under the fluorescent hum. "You changed the lock." "I changed the lock, and I'd do it again. Somebody was in here Tuesday night, Marjorie." "Somebody, or something. Raccoons are clever." "Raccoons don't wipe down the counter afterward." "...No. No, they don't." "And they don't take the sourdough starter and leave the till alone. Forty-two dollars in cash, untouched, but Great-Grandmother Hetty's starter is gone. Ninety years of continuous feeding, out the window." "You're certain it isn't just misplaced? You've been distracted since the festival announcement." "I know where I keep my own starter. Second shelf, blue crock, right beside the buttermilk." "Then whoever took it wanted to win a ribbon, not rob a bakery." "That's a very short list of people." "It's a list of nine, and I'll thank you to remember I'm on it." "You are. You're also the only one who brought me a casserole afterward, which either makes you innocent or extremely thorough." "Pour the coffee, and I'll be insulted later. Who else knew about the blue crock?" "Everyone who's ever taken my Thursday class." "Then start the kettle. We're going to need the sign-in sheets."
