The scent of freshly baked bread wafted through the air as the bell above the door jingled, announcing the arrival of a new customer. "Good morning, Louise!" called out a cheerful voice from behind the counter. "Morning, Margaret," came the reply. "Your cinnamon rolls were a hit at the church bake sale yesterday. I've got a few regulars who are already asking for more." Margaret beamed with pride. "Thank you, Louise. I'm always happy to help out with a good cause." There was a pause as Louise browsed the selection of pastries on display. "Say, Margaret... I couldn't help but notice that Mrs. Thompson wasn't at the bake sale. Is everything all right with her?" Margaret's smile faltered. "I'm afraid not. Have you heard about her missing necklace?" "No, I hadn't," replied Louise, her eyes widening. "What happened?" "Well," began Margaret, lowering her voice to a whisper, "She was supposed to wear it to the wedding last weekend, but when she went to get it out of her jewelry box, it was gone. She's convinced someone must have stolen it." "How terrible!" exclaimed Louise. "Do the police have any leads?" "Not yet," sighed Margaret. "But between you and me, I think there are a few people in this town who might not be as innocent as they seem..." The two women exchanged knowing glances before the bell jingled again, signaling the arrival of another customer. As they turned to greet the newcomer, the mystery of the missing necklace hung heavy in the air, adding an unexpected twist to the otherwise peaceful morning at the bakery.
