Background to elements of the plot
A short novel titled Georges by Dumas was published in 1843, before The Count of Monte Cristo was written. This novel is of particular interest to scholars because Dumas reused many of the ideas and plot devices in The Count of Monte Cristo.[5]

Dumas wrote that the germ of the idea of revenge as one theme in his novel The Count of Monte Cristo came from an anecdote (Le Diamant et la Vengeance[6]) published in a memoir of incidents in France in 1838, written by an archivist of the Paris police.[7][8] The archivist was Jacques Peuchet, and the multi-volume book was called Memoirs from the Archives of the Paris Police in English.[9] Dumas included this essay in one of the editions of his novel published in 1846.[10]

Peuchet related the tale of a shoemaker, Pierre Picaud, living in Nîmes in 1807, who was engaged to marry a rich woman when three jealous friends falsely accused him of being a spy on behalf of England in a period of wars between France and England. Picaud was placed under a form of house arrest in the Fenestrelle Fort, where he served as a servant to a rich Italian cleric. When the cleric died, he left his fortune to Picaud, whom he had begun to treat as a son. Picaud then spent years plotting his revenge on the three men who were responsible for his misfortune. He stabbed the first with a dagger on which the words "Number One" were printed, and then he poisoned the second. The third man's son he lured into crime and his daughter into prostitution, finally stabbing the man himself. This third man, named Loupian, had married Picaud's fiancée while Picaud was under arrest.[6]

In another of the true stories reported by Ashton-Wolfe, Peuchet describes a poisoning in a family.[10] This story is also mentioned in the Pléiade edition of this novel,[8] and it probably served as a model for the chapter of the murders inside the Villefort family. The introduction to the Pléiade edition mentions other sources from real life: a man named Abbé Faria existed, was imprisoned but did not die in prison; he died in 1819 and left no large legacy to anyone.[8] As for Dantès, his fate is quite different from his model in Peuchet's book, since that model is murdered by the "Caderousse" of the plot.
