In order to write “Christine” I went to Fontainebleau; in writing “Henri III.” I went to Blois; for “Les Trois Mousquetaires” I went to Boulogne and Béthune; for “Monte-Cristo” I returned to the Catalans and the Château d’If; for “Isaac Laquedem” I revisited Rome; and I certainly spent more time studying Jerusalem and Corinth from a distance than if I had gone there. This gives such a character of veracity to all that I write, that the personages whom I create become eventually such integral parts of the places in which I planted them that, as a consequence, many end by believing in their actual existence. There are even some people who claim to have known them. In this connection, dear readers, I am going to tell you something in confidence--only do not repeat it. I do not wish to injure honest fathers of families who live by this little industry, but if you go to Marseilles you will be shown there the house of Morel on the Cours, the house of Mercédès at the Catalans, and the dungeons of Dantès and Faria at the Château d’If. When I staged “Monte-Cristo” at the Theâtre-Historique, I wrote to Marseilles for a plan of the Château d’If, which was sent to me. This drawing was for the use of the scene painter. The artist to whom I had recourse forwarded me the desired plan. He even did better than I would have dared ask of him; he wrote beneath it: “View of the Château d’If, from the side where Dantès was thrown into the sea.” I have learned since that a worthy man, a guide attached to the Château d’If, sells pens made of fish-bone by the Abbé Faria himself. There is but one unfortunate circumstance concerning this; the fact is, Dantès and the Abbé Faria have never existed save in my imagination; consequently, Dantès could not have been precipitated from the top to the bottom of the Château d’If, nor could the Abbé Faria have made pens. But that is what comes from visiting these localities in person. Therefore, I wished to visit Varennes before commencing my novel, because the first chapter was to open in that city. Besides, historically, Varennes worried me considerably; the more I perused the historical accounts of Varennes, the less I was able to understand, topographically, the king’s arrest. I therefore proposed to my young friend, Paul Bocage, that he accompany me to Varennes. I was sure in advance that he would accept. To merely propose such a trip to his picturesque and charming mind was to make him bound from his chair to the tram. We took the railroad to Châlons. There we bargained with a livery-stable keeper, who agreed, for a consideration of ten francs a day, to furnish us with a horse and carriage. We were seven days on the trip, three days to go from Châlons to Varennes, one day to make the requisite local researches in the city, and three days to return from Varennes to Châlons.
