The Count of Monte Cristo also disguises himself as an Abbe and returns to find Caderousse still a poor man. He gives Caderousse a diamond, yet he knows this shall not bring Caderousse happiness. Caderousse's greed is far too great. The diamond is part of Caderousse's slow punishment. First, Caderousse kills a jeweler, his wife, and is then thrown into prison. The Count, disguised as a Lord Wilmore, later helps Caderousse escape from prison. Caderousse then attempts to rob the count, still not knowing that it is Dantes. During this robbery attempt, Caderousse is murdered by his accomplice, Benedetto. As Caderousse is dying, the Count whispers his identity in Caderousse's ear. Caderousse then cries out to God.
Fernand Mondego became a military hero and had married Mercedes who had given up hope to ever see Dantes again. Mercedes was unaware of the treachery of her husband. They have a fortune, and exist in Parisien society as the Count and Countess de Morcerf. The Count destroys Morcerf by revealing his military treachery to all of Parisien society. Monte Cristo had bought Haydee as a slave. This girl was once the daughter of Ali Pasha who was betrayed by Morcerf. She testifies that the Count sold her into slavery. Her father had been the Count de Morcerf's benefactor. Morcerf had killed her father, surrendered her father's Greek City to the Turks, and sold his wife and daughter into slavery. When this news is revealed to Paris, the Count de Morcerf is thus ruined. His wife and son flee, and he shoots himself.
Monsieur de Villefort had married twice. He has one daughter by his first wife and a son by his second wife. Valentine is his daughter. The Count destroys de Villefort by introducing Andrea Calvacanti into society. Benedetto, alias Calvacanti, is the son of Monsieur de Villefort and Madame Danglars. Long ago, Villefort had attempted to bury the newborn baby alive, but Bertuccio, now Monte Cristo's servant had dug the baby up and saved it. Villefort's crime is revealed in a court of law, since Calvacanti is on trial as an escaped convict. Villefort is thus destroyed. His wife as treacherous as he had also poisoned his entire family. Her motive was to gain a fortune for her son. The Count however, had saved Valentine, sinceMaximilien Morrel, the son of M. Morrel was in love with her. Villefort goes insane.
Danglars had become a rich banker. He has a wife and daughter. His wife is of noble birth, yet when Danglars married her, her repute as a woman was suspect. The Count destroys Danglars by opening credit with him for six million francs. Right when Danglars needs this money, the Count also takes a receipt for five million francs from him to cash. Danglars can no longer uphold his firm. He follows Danglars to Italy, once Danglars flees Paris. (Danglars has been alienated from his wife for years, and his daughter runs off, as a result of a failed marriage contract to Andrea Calvacanti. Monte Cristo had also arranged this failed enterprise. Danglars thus had no reason to stay in Paris.) Danglars tries to redeem his five million francs from Monte Cristo's firm in Italy. Once he does this, Monte Cristo's bandits follow him, and they destroy him financially by holding him captive and requiring him to pay vast sums of money to survive on a little food. Danglars is left with nothing and his hair turns white during his brief captivity with the Monte Cristo's bandits. Monte Cristo does not fail to inform Danglars his true identity.
Thus, the Count's revenge is now complete. He has succeeded in his quest for slow revenge. His enemies have suffered for their sins. He has one last meeting with Mercedes. Mercedes shall lead a life of prayer in a convent, for her son has gone to rebuild his future in the army. The Count of Monte Cristo had assumed the role of Providence by destroying all that had been built by his enemies during his long years of imprisonment. He must now leave. After leaving much of his belongings to Maximilien Morrel and Valentine, to whom he wishes eternal love and happiness, he leaves aboard a ship with Haydee his own new love
