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 jingles like a cautious friend this morning." "Yeah, and the air smells of cinnamon and trouble, as always." "The lavender sugar jar's been moved again, not by us." "And the note slipped under the flour bin? Not a good sign." "What did it say this time?" "It said, 'The true recipe hides where daylight ends.'" "Someone's playing chef and thief with our family recipe." "Or it's a prank to see which one of us blinks first." "I blinked yesterday, and the croissant went flat, remember?" "This morning the staff meeting smelled of burnt sugar and fear." "Then check the ledger; maybe someone paid for a tip." "The ledger's clean; the only thing paid is attention." "What about the old key under the doormat? We never moved it." "The doormat key? No, I recall Mrs. Hale hid it there." "We should go to the mill after closing, if we must." "And what will we tell the town when flour rains down?" "That we kept baking and maybe unmasked a missing heirloom recipe." "Then let's bake bravely and let the truth rise with the bread." "Meanwhile the town square waits with gossip while the oven cools, but patience bakes best." "Then we fold our sleeves, set the timer, and guard the kitchen like a secret."
