When M. and Mme Loisel realized that the necklace was missing, they tried finding out where she could have possibly lost it. They concluded that it might have dropped in the cab they were traveling in. But they did not remember its number.So, in an attempt to find the necklace, 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. Meanwhile he asked Matilda to write a letter to Mme Forestier, explaining that she had broken the clasp of the necklace and would get it repaired and return it soon. This gave them time to find the necklace. However, they eventually decided to replace the necklace with a new one.
