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.

“Those croissants look guilty.” “Guilty of what, exactly?” “Conspiracy. They’re huddled together like they know something about Mr. Duffy’s missing pie.” “Duffy doesn’t lose things. He misplaces them loudly and then accuses everyone within a three-block radius.” “True, but he swears he left the blackberry pie on that windowsill.” “Right where you’re standing. Convenient.” “Oh, please. If I stole it, do you think I’d be buying a bran muffin? Criminals choose éclairs.” “Maybe that’s your genius. Hide your sins behind fiber.” “Very funny. Look, the sill is spotless. No crumbs, no juice stains. Whoever took it cleaned up.” “In this town? People can’t even return library books on time. We’re supposed to believe we’ve got a tidy thief?” “Unless it never made it to the window.” “You’re accusing Mrs. Pritchard of lying? She threatened me with a rolling pin at six a.m. over that pie.” “She threatened the whole town. Maybe the pie collapsed and she didn’t want to admit it.” “Or maybe someone wanted that recipe badly enough to make the pie disappear.” “You think someone stole a whole pie just to decode a secret crust?” “In Maple Falls? Absolutely. Around here, people kill for less than Mrs. Pritchard’s butter ratio.”
