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 bell above the Warm Whisk Bakery door jingled softly, letting in the crisp autumn breeze. Sunlight danced across the oak counter, where trays of golden scones steamed beside jars of wildberry jam. Flour dusted the air like fairy dust. “You won’t believe what I heard last night at the fair.” “Try me. Was it about Mrs. Hargrove’s missing prize jam again?” “Worse. Footprints—muddy ones—leading right from her booth to the mayor’s tent. And they match those fancy boots he flashed at bingo.” “No! That old goat? But why steal jam? He’s got the sweet tooth of a horse, sure, but…” “It’s not the jam. It’s the recipe. Her secret ingredient? It’s the same one swiped from my shop two weeks back. Cinnamon from that rare island spice.” “Your secret? The one you guard like a dragon’s hoard? Oh, Mabel, we’ve got to snoop.” “Tonight? After closing, with flashlights and my rolling pin for luck?” “Perfect. Bring extra scones—bait for any sticky-fingered lurkers.” They clinked coffee mugs, eyes sparkling with mischief, as the oven timer pinged like a clue.
