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 morning light filtered through the checkered curtains of Sweet Crumb Bakery, casting warm squares across the flour-dusted counter. The scent of cinnamon rolls hung heavy in the air, competing with fresh coffee and something darker—suspicion. "You heard about Margaret's garden shed, I suppose." "Heard about it? I drove past it this morning. Police tape everywhere. Looked like something out of a television program." "They found Harold's missing ledger in there. Tucked right behind a bag of potting soil." "Margaret wouldn't know a ledger from a hymnal. Someone planted it." "That's a convenient thing to believe, considering she owes you money." A long pause settled between them. The espresso machine hissed and sputtered. A tray of scones slid from the oven, golden and perfectly cracked on top. "I'm going to pretend you didn't say that. Cream or sugar?" "Black. And I didn't mean anything by it. I'm just saying this town has a way of pointing fingers at the wrong people while the right ones keep on smiling." "Harold kept secrets from everyone. Maybe whoever wanted that ledger hidden knew exactly whose shed would raise the fewest questions." "Or the most." The bell above the door chimed, and they both went quiet.
