The Count of Monte Cristo

From Wikipedia:

The Count of Monte Cristo (French: Le Comte de Monte-Cristo) is an adventure novel written by French author Alexandre Dumas (père) completed in 1844. It is one of the author's most popular works, along with The Three Musketeers. Like many of his novels, it was expanded from plot outlines suggested by his collaborating ghostwriter Auguste Maquet.

The story takes place in France, Italy, and islands in the Mediterranean during the historical events of 1815–1839: the era of the Bourbon Restoration through the reign of Louis-Philippe of France. It begins on the day that Napoleon left his first island of exile, Elba, beginning the Hundred Days period when Napoleon returned to power. The historical setting is a fundamental element of the book, an adventure story centrally concerned with themes of hope, justice, vengeance, mercy, and forgiveness.

Before he can marry his fiancée Mercédès, Edmond Dantès, a French nineteen-year-old first mate of the Pharaon, is falsely accused of treason, arrested, and imprisoned without trial in the Château d'If, a grim island fortress off Marseille. A fellow prisoner, Abbé Faria, correctly deduces that romantic rival Fernand Mondego, envious crewmate Danglars, and double-dealing magistrate De Villefort are responsible. Over the course of their long imprisonment, Faria educates Dantès and tells him of a cache of treasure he found. After Faria dies, Dantès escapes and finds the treasure. As the powerful and mysterious Count of Monte Cristo, he enters the fashionable Parisian world of the 1830s to avenge himself.

The book is considered a literary classic today. According to Lucy Sante, "The Count of Monte Cristo has become a fixture of Western civilization's literature."
