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 tinkled, and flour drifted like snow on the counter." "If mornings are soft, this one smells like secrets bruised by sugar." "I found a folded note wedged in the lemon curd tray, whispered to be discreet." "Discreet is also how you bake, but it never keeps a thief away." "Who would steal a recipe that makes the town grin at dawn?" "Someone who wants the festival to collapse, perhaps, or deserves a quieter square." "The ledger shows a hurried payment from a name we pretend not to know." "Names in ledgers never stay hidden; they bubble up like steam from the oven." "Check the delivery log; the crate from yesterday smells of vanilla and deceit." "If the starter is tampered with, the bread won't rise and the crowd will notice." "Then we follow the crumbs, not the rumors, and begin with the back room." "Careful with your steps; the floor boards groan when you stare too hard." "I hear a clink in the tin can—perhaps a key, perhaps a confession." "Then we unlock the mystery before the town chews its own suspicions to crumbs." "Tonight the glaze must shine, and so must the truth behind it." "Agreed, and if we solve it, the bakery stays, the town stays sweet."
