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 hit it. "You're late. The cinnamon rolls have been out since six." "Sorry. I was busy finding out who broke into Mrs. Pemberton's garden shed." "Someone broke into her shed?" "Nothing taken, except her prize-winning gnome. But there were muddy footprints leading straight to the back of this bakery." "Well, that's ridiculous. I'd have noticed." "Would you? You were up to your elbows in rye dough all night, and you sleep like a stone once you're home." "Are you accusing me of something?" "Only of being observant. Tell me, did you leave the back door unlocked?" "Just for the milk delivery. Why?" "Because there's a gnome sitting in your walk-in refrigerator, wearing a tiny apron." "Oh, for heaven's sake. That's not a gnome, that's Reginald. He's a joke Mr. Halloway plays every April." "Then why is Reginald's hat missing?" "Because... hmm." "Because it's stuffed in the flour bin, next to a note." "A note? What does it say?" "'Meet me at the church bell tower at midnight. Bring the recipe.'" "Well. Pour yourself some coffee. It seems we have a long day ahead."
