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 morning light spilled through the front windows of Sweet Crumb Bakery, catching the flour dust that drifted lazily through the air. The bell above the door chimed, and muddy boots tracked across the black-and-white tile floor. "You heard about Margaret's garden shed, I suppose." "Heard about it? I could see the police lights from my kitchen window at two in the morning." A cinnamon roll was slid across the counter on a small blue plate, still warm enough to send up curls of steam. "They're saying she interrupted a burglar. But nothing was stolen." "Nothing she's told anyone about, anyway." A long pause filled the space between them, occupied only by the gurgle of the coffee pot and the soft tearing of pastry. "You know what I found strange? That locked cabinet of hers was pried open. The one she said held old Christmas decorations." "Margaret never decorated for Christmas a day in her life." "Exactly." The coffee was poured slowly, deliberately, into a ceramic mug with a chipped handle. Outside, a police cruiser rolled past the bakery window without stopping. "I'm going to bring her a loaf of sourdough this afternoon." "I'll come with you."
