Secret affair between Gérard de Villefort and Hermine Danglars

The secret affair between Gérard de Villefort and Hermine Danglars is one of the most consequential hidden relationships in the novel, a liaison that produces an illegitimate child, drives Villefort to attempted infanticide, and ultimately provides the Count of Monte Cristo with the leverage to destroy both families. The relationship is rooted in the period before either party's current marriage: Villefort, then the deputy procureur at Marseilles, and Hermine, then the wife of the Marquis de Nargonne, conduct their affair in a house at Auteuil belonging to Villefort's father-in-law, the Marquis de Saint-Meran. The house, at 28 Rue de la Fontaine, becomes the site of their secret meetings, with Hermine entering through a small garden gate while Villefort arrives on horseback or by carriage, leaving the vehicle at a nearby inn.

The Illegitimate Child and Its Burial

The affair results in a pregnancy. On the night of 20 September 1817, Hermine gives birth in the red-damask-hung bedroom of the Auteuil house. The child, a boy, is born apparently lifeless. Villefort, believing the infant dead, wraps it in a fine linen napkin marked with a baron's coronet and the letter H (for Hermine), places it in a small box, and buries it in the garden under a plane tree. As he is trampling the earth to conceal the grave, he is stabbed by Bertuccio, a Corsican seeking vengeance for his brother's murder. Bertuccio, believing he has killed Villefort, digs up the box, discovers the infant is still alive, and rescues it. He takes the child to the foundling asylum in Paris, keeping half of the marked napkin as a means of future identification. The child, registered as number 37, is later claimed by a woman from Rogliano and raised in Corsica under the name Benedetto.

The Secret's Persistence and Revelation

For over twenty years, Villefort and Hermine keep the affair and the child's fate hidden. Hermine marries the Baron Danglars, becoming Madame Danglars, while Villefort marries Renee de Saint-Meran and rises to become the king's attorney in Paris. The secret is violently resurrected when Monte Cristo, who has learned the entire history from Bertuccio, orchestrates a series of revelations. At a dinner party at his Auteuil house, Monte Cristo deliberately leads the conversation to the buried infant, causing both Villefort and Madame Danglars to faint. Later, during the trial of Benedetto (now calling himself Andrea Cavalcanti) for the murder of Caderousse, the young man publicly declares himself to be the son of Villefort, born on the night of 27 September 1817 at Auteuil, and describes in detail the napkin and the burial. Villefort, confronted with this irrefutable testimony, confesses his guilt before the entire court.

Consequences and Catastrophe

The exposure of the affair triggers a cascade of catastrophes. Villefort, already reeling from the revelation, returns home to find that his wife Heloise has poisoned herself and their son Edward. He goes mad, digging frantically in his garden. Madame Danglars, exposed as the mother of a convicted murderer, faints in the courtroom and is carried out. The affair's revelation also destroys the planned marriage between Albert de Morcerf and Eugenie Danglars, as the Danglars family is now irredeemably tainted. Monte Cristo, who has orchestrated the entire chain of revelations, confronts Villefort in his study, revealing himself as Edmond Dantes, the man Villefort unjustly imprisoned. The secret affair, born in secrecy and buried in a garden, thus becomes the instrument through which Monte Cristo exacts his most complete and terrible vengeance, destroying the house of Villefort and exposing the corruption at the heart of the Danglars family.
