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 aroma of cinnamon scones and fresh coffee enveloped the cozy nook of Millie's Bakery, where sunlight filtered through lace curtains onto checkered tablecloths. Flour-dusted counters gleamed behind the glass case, and a chalkboard announced the daily special: blueberry crumble pie. "Did you hear about Mayor Hargrove? Found stiff as a board in his armchair last night." "Poisoned, they say. Right after the town picnic. That pie he devoured—remember how he raved about it?" "From here? No ma'am, ours don't kill. But Ethel's entry in the contest was suspiciously absent." "Ethel? The one who argued with him over the zoning vote? Her rhubarb pie looked perfect, but smelled off." "Exactly. And her apron had a purple stain—huckleberry juice? Hargrove's lips were blue." "Shh, not so loud. Millie might overhear." "Millie's the best sleuth in Willow Creek. Bet she'll bake clues into tomorrow's loaves." A tray clattered nearby, steam rising from apple turnovers. Outside, autumn leaves swirled past the window, whispering secrets of the small town's unraveling mystery.
