Mysteries of Lisbon plunges us into a veritable whirlwind of adventures and escapades, coincidences and revelations, sentiments and violent passions, vengeance and love affairs, all wrapped in a rhapsodic voyage that takes us from Portugal, France, Italy, and as far as Brazil. In this Lisbon of intrigue and hidden identities, we encounter a series of characters all somewhat linked to the destiny of Pedro da Silva, an orphan in a boarding school. Father Dinis, a descendent of the aristocratic libertines, later becomes a hero who defends justice; a countess maddened by her jealousy and set on vengeance and a prosperous businessman who mysteriously made his fortune as a bloodthirsty pirate. These and many more characters all cross in a story set in the 19th century while searching for the true identity of our main character.
