Le comte de Monte-Cristo, Tome III

Edmond Dantès, a young seaman with a promising future, is arrested at his wedding ceremony under calomnious charges, and locked up in the Chateau d'If for 14 years. During this time, he secretly meets another detainee, l'Abbé Faria, an erudite believed to be insane, who becomes his friend and teacher, and who, upon his death, gives Edmond the secret to a hidden treasure.
