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 Curious Customer The bell above the bakery door chimed as Margaret pushed it open, the aroma of fresh cinnamon rolls enveloping her immediately. "You're here early today." "Couldn't sleep. Besides, I wanted to catch you before the morning rush." Margaret leaned against the counter, studying the young baker's flour-dusted apron. "I heard about the incident at the library last night." "Word travels fast." Sarah pulled a tray of croissants from the oven, her movements deliberate. "It wasn't as dramatic as people are making it sound." "Someone broke in and ransacked the rare books section. That's not nothing." "I know, but..." Sarah set down her tray with a soft clatter. "I was there. I'd left my scarf by the reading table. When I went back around nine, the door was already open." Margaret's eyes narrowed. "You didn't call the police?" "Of course I did. They said nothing was actually stolen, just moved around." Sarah wiped her hands on her apron. "It felt personal, Margaret. Like someone was looking for something specific." "Did you tell the officers that?" "They didn't ask the right questions." Sarah met Margaret's gaze. "But I think you might." Margaret smiled knowingly. "Then I suppose we should talk properly. Lock the door—we have some investigating to do."
