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 smell of cardamom buns hung thick in the air, and the ovens ticked as they cooled. "You've scorched the second tray." "I have not. That's caramelization. There's a difference, and I'd expect a woman who judges the county pie competition to know it." "Don't change the subject, Marjorie." "I wasn't aware we had one." "Cyril Bledsoe. Sitting right there at the corner table Tuesday morning, arguing with somebody on the telephone about a key. And now he's in hospital with a cracked skull and everyone's saying he fell down his own cellar stairs." "People do fall." "People who've lived in the same house forty-one years don't fall down stairs they could walk in their sleep." "You've got flour on your chin." "I've got a theory on my chin, and you'd do well to listen. He ordered two coffees. Two. Who was the second one for?" "How should I know? I pour, I don't interrogate." "You remember every order in this town going back to 1994." "...It was for a woman. Tall. Sunglasses indoors, in October, which ought to be a crime all on its own. She left before he did and she didn't touch her cup." "And you weren't going to mention this?" "I'm mentioning it now. Hand me the piping bag."
