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.

Model response

AI
The bell over the door jingled, and flour dust rose in the morning light like something startled. "You're early. I haven't even got the cinnamon buns out." "I'm not here for buns. I'm here because Harold Pettibone's van was parked outside your back door at half eleven last night." "Was it." "It was. And Harold Pettibone has been dead a week and buried since Tuesday." "Then it wasn't his van, was it? Sit down. You look like a woman who hasn't had her tea." "Don't you dare mother me. I know that van. Rust along the wheel arch, that awful bumper sticker about trout." "Margaret. There are four hundred white vans in this county." "With trout stickers?" A long pause, filled with the scrape of a tray being pulled from the oven. "His nephew has the van now. He's been bringing me eggs. Cheap, from his own hens, and I'd rather not have the Health Board asking questions about provenance, so I'd appreciate your discretion." "Eggs. At half eleven at night." "Hens are unpredictable." "You're a terrible liar. You've gone the colour of your own raspberry glaze." "Have a bun, Margaret." "I'll have two. And then you'll tell me the truth."
