The Holy Grail

S1 E2: In 2003, Dan Brown published "The DaVinci Code". Through mystical clues, the author leads the reader on a sort of treasure hunt, in search of the mysterious Holy Grail. As a matter of fact, we learn that the word Holy Grail does not mean the cup used by Christ at the Last Supper, but rather a genealogical line traced from Jesus and Mary Magdalene's union. Occult reality or literary fantasy?
