A reader sent the below re the novel. I never put it together - "Dantes" should be a giveaway:
The novel is much more than an adventure, though, but a story of redemption. Alexandre Dumas structures the tale on the lines of Dante's Divina Commedia. The life of Dantès takes a wrong turn, and he ends up in the Inferno of Chateau d'If, with Abbé Faria playing the part of Virgil. Dantès then enters the Purgatorio of revenge and retribution. Finally cleansed of his hate, Dantès finds the enlightenment of Paradiso.
“Until the day when God shall deign to reveal the future to man, all human wisdom is summed up in these two words, -Wait and hope.” — Alexandre Dumas (père)
