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 chimed as Margaret stepped inside, the warm scent of cinnamon rolls wrapping around her like a familiar hug. "You heard about the Hendersons, I suppose." "Who hasn't? The whole street was talking about it before seven this morning." A paper bag rustled across the counter. "Your usual?" "Please. Do you think she actually did it?" "Eleanor Henderson? The woman volunteers at the library every Tuesday and grows prize-winning dahlias. Does that sound like someone who'd empty a bank account?" "People surprise you." Margaret peered into the glass case at the lemon tarts. "I'll take one of those too. The thing is, I saw her car parked outside the old Millbrook building on Thursday night. Late." A pair of tongs paused in midair. "That building's been empty for two years." "Exactly what I thought." "You should tell Sheriff Paulson." "And say what? That I was driving past at eleven o'clock because I couldn't sleep?" Margaret tucked the bag under her arm and slid a ten across the counter. "Besides, I'd rather figure it out myself first." "Margaret." A pause, loaded with familiar exasperation. "Keep me posted." "Obviously."
