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.

“Does your almond croissant usually come with a side of police tape?” “Only on Thursdays. You want that warmed up or left as evidence?” “Don’t joke. They’re interviewing Mrs. Potts right now. She looks like she’s going to faint into the cinnamon rolls.” “Mrs. Potts faints every time the mayor sneezes. What did they say happened?” “Health inspector collapsed, right there by the display case. Face-first into a strawberry scone.” “Tragic. Those are the last of the summer berries. Did he choke?” “They think poison. He’d only had your coffee and a bite of quiche.” “Well, that narrows it down to every soul in Maplebridge. Half the town lives on my quiche.” “You’re remarkably calm for someone whose name is on the front window.” “I’ll panic once they stop buying eclairs. Until then, I have a mortgage. Besides, I know what went into that quiche.” “You’re sure no one could have slipped something in? The kitchen door was propped open.” “For cooling trays. Not for amateur assassins. Though I did see Harold lurking back there.” “Harold lurks everywhere. It’s his personality.” “He hates the inspector. Failed him on those food truck permits.” “Motives are plentiful. Opportunity, less so.” “You planning to investigate?” “I just came in for a croissant.” “And now you’re leaving with a mystery.” “Fine. Start with Harold?” “I’ll pack us two alibis and four eclairs.” “Four?” “Investigations burn calories.”
