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 Investigation The bell above the bakery door chimed as Margaret stepped inside, the aroma of fresh cinnamon rolls enveloping her like a warm embrace. "You're up early today." "Couldn't sleep. Not after what happened to poor Eleanor's prize-winning jam." Margaret leaned against the counter, eyeing the display of pastries. "The competition was supposed to be next week. Someone must have gotten desperate." "That's what troubles me. Eleanor's been winning for fifteen years straight. Who would sabotage her?" "Well, her neighbor Patricia has been experimenting with a new recipe. I've seen her buying unusual ingredients lately." Margaret picked up a croissant, examining it thoughtfully. "Patricia? But they're friends, aren't they?" "Were friends. Things changed after Eleanor refused to share her secret ingredient list." The baker wiped flour from her hands, her expression grave. "So you think Patricia poisoned it?" "I didn't say poisoned. Just... altered. Enough to disqualify Eleanor from competing." Margaret set the croissant down slowly. "We need to talk to Patricia. And I'd like to see Eleanor's kitchen myself." "Thought you might say that. I already called her. You're having breakfast there in an hour."
