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.

"I'm telling you, it wasn't the butter." "Then why did the Mayor turn absolutely purple right before he face-planted into the display case?" "Well, it definitely wasn't the butter. I churn it myself." "What about the blueberries in the scone?" "Picked fresh from Miller's farm yesterday morning." "The same Henry Miller who lost the zoning board election to the Mayor last Tuesday?" "Don't be ridiculous. Henry wouldn't know a poisonous berry from a perfectly ripe gooseberry." "He reads a lot of Agatha Christie. I saw him checking out *A Murder is Announced* twice last month." "That proves nothing. Pass me that piping bag, will you? The vanilla buttercream." "Here. But you have to admit, it’s a bit suspicious. The Mayor comes in every single morning for his pastry, at exactly eight-fifteen." "Eight-ten." "Whatever. And yesterday, Henry was lingering by the day-old rack right before the Mayor walked in." "He was looking at the discounted almond croissants." "He was holding a little glass vial of something, I swear." "It was almond extract! You’re getting powdered sugar all over the counter, stop fidgeting." "I'm just saying, if the sheriff tests the crumbs of that scone..." "They won't find a thing. We use strictly all-natural ingredients here." "Does that include the cyanide?"
