What were the steps Madame and Monsieur Loisel took to return the necklace to Madame Forestier?

When
Madame Loisel and Monsieur Loisel discover that the necklace is missing from her neck they begin
to panic. Mr. Loisel went back to every place they had been to see if he could find it. 
"He went to the police station,to the newspapers to post a reward, to the cab companies,
and anywhere else he might find hope in finding the necklace."  To no avail, the couple
could not find the necxklace and knew they had to replace it.  They wrote a letter to Madame
Forestier asking for a week because the clasp had broken and they wanted to get it fixed.  They
visited a jeweler with the case the necklace had come in.  He said he did not sell the necklace
just the case. They continued to go from jeweler to jeweler until they found a necklace that
looked exactly like the one they lost.  It was store in an area of Paris called, "Palais
Royal."  The jeweler would sell it to them for thirty-six francs.  Mr. Loisel had eighteen
thousand francs he inherited from his father and he "signed notes, made ruinous deals, and
visited loan sharks."  They were then able to buy the necklace and give it to Madame
Forestier.  She took the necklace and never opened the case.

From that point
on Madame Loisel and Monsieur Loisel lived horrid lives for the next ten years trying to pay
back all the debts only to find out that the truth is always the better
route.
