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 above the door jingled, and flour puffed from the counter as the last tray of scones landed. "You're early." "The sheriff's car is parked outside Mr. Halloran's shop. I thought you'd want to know." "I already know. Half the town knows. Cinnamon roll?" "Two, please. Did you hear what they found?" "A cracked window and an empty cash box. That's what Doris said, anyway, and Doris also swore the Hendersons were in witness protection." "Doris is sometimes right." "Doris is sometimes lucky. Here, they're still warm." "Thank you. Wait, what's this? There's a note tucked under the napkin." "That's odd. I didn't put anything there." "It says, 'Ask the baker where the missing key went.'" "Well, that's ridiculous. Let me see that. Hmm." "Your hands are shaking." "It's the espresso. Too much espresso." "You haven't touched the espresso machine since I walked in." "Then it's the cold." "It's July." "Fine. The spare key to Halloran's has hung on that hook for ten years. Since he lent it to me during the flood." "And the hook is empty." "The hook is empty." "Then I suppose we should have a very quiet conversation with the sheriff." "After the scones. Everything's better after scones."
