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 door jingled as warm air rushed out to greet the morning chill. "You're here early. The cinnamon rolls aren't even out yet." "I'm not here for the rolls, Margaret. I'm here about Edith." "What about her? She was just in yesterday, fussing over the lemon tarts like always." "That's just it. She never made it home." The sound of a tray clattering against the counter filled the silence. "You can't be serious. Edith's lived on Maple Street for forty years. She could walk that route blindfolded." "Her sister called me this morning. The bed wasn't slept in. No note, nothing." "And you came to the bakery first? Shouldn't you be out looking?" "I am looking. You're the last person who saw her, near as I can tell. Did she say anything strange? Anything at all?" A long pause, broken only by the ticking of the wall clock. "Now that you mention it... she did seem distracted. Kept glancing out the window like she was waiting for someone. Wouldn't touch her tea." "Did you see who?" "No. But when she left, she didn't take her usual bag of day-olds. First time in years." "Margaret, I think we'd better sit down."
