In this chapter, the story begins with Monte Cristo and his steward, Bertuccio, embarking on a mysterious journey to a property in Auteuil. As they descend the staircase and prepare to depart, Monte Cristo notices that Bertuccio, a Corsican, makes a sign of the cross and mutters a prayer, indicating his deep unease about the trip.
As they approach Auteuil, Bertuccio's anxiety intensifies. He becomes increasingly nervous and feverishly scans every house they pass. Monte Cristo, curious and persistent, instructs Bertuccio to direct the carriage to Rue de la Fontaine, No. 28, a location that seems to deeply disturb the steward. Despite his evident distress, Bertuccio complies, though his fear is palpable.
Upon arrival, Monte Cristo instructs Bertuccio to knock and announce their presence. The concierge, who answers the door, is informed that Monte Cristo is the new owner of the house. The concierge explains that the previous owner was the Marquis of Saint-Méran, who seldom visited the property. This information triggers an even more intense reaction in Bertuccio, who grows pale and barely maintains his composure.
Monte Cristo, noticing Bertuccio's distress, pushes forward, asking to be shown around the house. Bertuccio, though terrified, leads the way, trembling as they explore the property. They eventually reach a private staircase leading to the garden. Monte Cristo, curious, insists on exploring further, despite Bertuccio's growing agitation. When they reach a particular spot in the garden, Bertuccio finally breaks down, pleading with Monte Cristo to leave the area, as it is the exact location where a significant and terrible event occurred in his past.
Monte Cristo, undeterred and intrigued, presses Bertuccio for more information. Bertuccio, overwhelmed by his memories, begins to reveal that it was in this house, in this very spot, where he exacted revenge—a crime he had never fully confessed except to the Abbé Busoni. Monte Cristo learns that Bertuccio's vengeance was not against the Marquis of Saint-Méran but someone else, though he had carried out his act on this property.
Bertuccio explains that the house's connection to his crime was no coincidence, believing it to be a matter of fate or providence. Monte Cristo, half-mocking and half-intrigued, urges Bertuccio to confess the entire story. Bertuccio, terrified of being dismissed from Monte Cristo's service and sent to his death, begins to tell his tale, revealing that his target was none other than the former royal attorney, M. de Villefort, a man with a reputation for severe and upright justice, whom Bertuccio now calls a villain.
The chapter ends with Monte Cristo sitting down, fully captivated, and urging Bertuccio to recount the full details of his vendetta against Villefort, thus setting the stage for a deeper exploration of Bertuccio's dark past and the intertwining fates of the characters involved.
