What do M. and Mme Loisel do next?
When M. and Mme Loisel realized that the necklace was missing, they tried finding out where she could have lost it. They concluded that it could have been dropped in the cab. They did not know its number. Therefore, Loisel went over the track where they had walked. When he found nothing, he went to the police and to the cab offices. He even put an advertisement in the newspapers, offering a reward. He then asked Matilda to write a letter to Mme Forestier, explaining that she had broken the clasp of the necklace and would get it repaired. This gave them time to find the necklace. However, they eventually decided to replace the necklace with a new one.
