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 small-town bakery, Hearth & Crust, glows with a steady warmth. Flour dust drifts in sunlight from the window, and the smell of butter and spice fills the air. Two bakers stand by the counter, trading whispers as the day begins.] "Back door was ajar again last night, as if inviting trouble." "Or the wind learned a new secret from the flour sacks, perhaps." "Vanilla smeared across the mixer—definitely not from today, and not by accident." "Someone moved the spice jars with the care of a careful thief, almost reverent." "And the recipe notebook? It’s light where it should be heavy, suspiciously so." "A missing page could spell disaster for Mrs. Holloway's festival glaze." "We should zero in on the ledger, the delivery log, and any late returns." "And bake a decoy batch to lure the lurker into the open." "If we trap them here, the town will sleep better with warm loaves." "First, sweep the shelves, then check cameras, then taste-test the decoy." "Right, and keep your voice calm—no heroes, just a careful plan." "Quiet confidence tastes of butter and cinnamon; we’ll get to the bottom."
