Edmond Dantès and his friend, the Abbé Faria, navigate a narrow underground passage to reach Faria’s cell. In the cell, Dantès is eager to see the “treasures” that Faria has promised, but Faria first explains how he tells time using sunlight and markings on the wall, which is more accurate than a watch. This explanation baffles Dantès, who struggles to grasp the scientific principles.
Faria then reveals his hidden manuscripts, including a detailed work on the monarchy of Italy, written on strips of cloth with a homemade pen made from a slender stick and cartilage. The ink was made from materials Faria gathered in prison. Faria shows Dantès various items he’s crafted, including a sharp penknife made from an old candlestick, and a lamp fashioned from melted fat and linen for light at night. Dantès is astonished by Faria’s ingenuity and perseverance.
As they continue, Faria shows Dantès another hidden treasure: a rope ladder made from torn shirts and bed linens, which he crafted in case of a chance to escape. Faria explains how he secretly obtained materials over years of imprisonment.
The conversation shifts to Dantès’ own life, where Faria applies his analytical skills to uncover the source of Dantès’ misfortunes. They deduce that Danglars, who held a grudge against Dantès, likely wrote the anonymous letter that led to his arrest. Faria helps Dantès see the connections between those who might benefit from his downfall, including Fernand, who was in love with Dantès’ fiancée, Mercédès.
Finally, Faria expresses suspicion about the deputy who examined Dantès during his arrest. The deputy showed unusual sympathy by burning a letter that could have incriminated Dantès, which Faria finds suspicious and suggests may indicate deeper corruption. The story leaves Dantès realizing the extent of the treachery against him and the complexities of the motives of his enemies.
The abbé and Dantès further discuss their plan for escape from prison. The abbé explains that while human knowledge is limited and that he can teach Dantès many things in two years, he emphasizes that true understanding comes from philosophy, which can't be taught but is applied through the sciences.
The abbé and Dantès embark on an educational journey together, with Dantès quickly mastering several languages and subjects due to his exceptional memory and aptitude. Over time, Dantès becomes a new man, absorbing knowledge and skills with enthusiasm. However, the abbé grows increasingly melancholic and obsessed with the thought of escape.
Eventually, the abbé reveals his escape plan, which involves digging a tunnel from their cells to the gallery where a sentinel is stationed. The plan is to create a trap for the sentinel and use a rope ladder to descend from the prison walls. The work takes over a year to complete, during which the two men carefully excavate their tunnel and avoid detection.
The night before their planned escape, the abbé suffers a severe illness, resembling a fit of apoplexy. Dantès is forced to administer a remedy to the abbé to save his life. Despite his weakened state, the abbé continues to express doubt about their escape plan, fearing that his illness will permanently disable him. He insists that Dantès should go on without him, but Dantès vows to stay and support the abbé, pledging to never leave him.
Faria, recognizing the gravity of their situation, advises Dantès to cover up their tunnel to avoid detection. Despite the obstacles, the bond between Dantès and Faria remains strong, and Dantès' loyalty is unwavering
