Model input
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 scent of cinnamon and vanilla wafted through Sweet Loaf Bakery, where sunlight danced across checkered floors and glass cases brimming with scones and tarts. Two women huddled at a corner table, teacups steaming between them. "Did you see the way Mrs. Finch bolted out of the town hall meeting yesterday? Pale as a ghost." "Indeed. And right after old Mr. Wilkins clutched his chest during tea. Heart attack, they say, but I smelled almonds on his breath." "Almonds? Like in those cherry bakewell tarts she sells? Cyanide, you mean?" "Shh! Precisely. Wilkins was poking into her late husband's accounts—rumors of embezzled festival funds. She baked for the event, remember?" "Her hands shook when she handed me my usual this morning. Spilled flour everywhere. And that new assistant of hers, always lurking..." "Mark my words, it's no coincidence the recipe book vanished last week. Poisoned pages, perhaps?" A bell tinkled as the door opened. Both women straightened, sipping their tea with forced smiles. "More cream?" one whispered. "Not unless it's untainted."
