The novel is presented as a translation (by "Jean Francois Alden") of memoirs by Louis de Conte, a fictionalized version of Joan of Arc's page, Louis de Contes.
"I like Joan of Arc best of all my books; and it is the best; I know it perfectly well. And besides, it furnished me seven times the pleasure afforded me by any of the others; twelve years of preparation, and two years of writing. The others need no preparation and got none." -- Mark Twain
