A guest named Jane checks out of a luxurious hotel after a week-long stay. A few hours later, she realizes that she left her diamond necklace, a family heirloom, in her room. Jane contacts the hotel's lost and found department to report her missing necklace.

After a thorough investigation, the hotel staff discovers that the necklace was mistakenly taken by a housekeeper, who had found it on the floor after Jane's departure. The necklace is promptly returned to Jane, and the hotel takes steps to improve staff training and protocols to prevent similar incidents in the future.
