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.

"Another batch of cinnamon rolls gone missing?" "Third morning this week. I count them twice before I lock up, Margaret. Twice." "And the back door?" "Bolted. Chain and all. Yet this was sitting on the flour bin when I came in." "A button. Brass, with an anchor on it." "Looks like it came off a captain's coat." "There hasn't been a captain in Pemberton Cove since old Hollis died." "Which is exactly what worries me." "Or it's what somebody *wants* you to think. Who else has a key?" "Only Dolly, my niece. And she's been at her mother's in Bristol all week." "Has she, now? Because I could have sworn I saw her on Tuesday, buying thread at Fenwick's." "That's impossible. She'd have stopped in for tea." "Unless she didn't want to be seen. Tell me, dear, has anything else changed? Any little thing?" "Well... the sugar jar's been moved. And there was a crumb trail leading toward the cellar door." "The cellar? You never mentioned a cellar." "I never go down there. It's been locked since Hollis sold me the building." "Then fetch your lantern, love. And bring a few cinnamon rolls. If we're right, someone's very hungry."
