Sophie Neveu
Sophie Neveu is a fictional character in the novel, The Da Vinci Code. Neveu is the granddaughter of Jacques Saunière. She is a French National Police cryptographer, who studied at the Royal Holloway, University of London Information Security Group.
She was raised by her grandfather from an early age, after her parents were killed in a car accident. Her grandfather used to call her "Princesse Sophie" and trained her to solve complicated word puzzles. As a young girl, she accidentally discovered a strange key in her grandfather's room inscribed with the initials "P.S.". Later, as a college student, she made a surprise visit to her grandfather's house in Normandy and, silently horrified, she observed him participating in the Hieros Gamos, a sex ritual. The incident led to her estrangement with her grandfather for ten years until the night of his murder.
Trivia
The French word "neveu" means "nephew". The name "Sophia" is from the Greek word for wisdom. Sophia is also considered the Goddess of Wisdom. Some cultures believe she represents the Goddess that reigns with God.
Movie portrayal
In the movie, Sophie is portrayed by French actress Audrey Tautou.
The film's character is partially different from that of the book's. In the film she is a descendant of the Merovingians, and a living descendant of Jesus Christ, first hinted when her adoptive grandfather calls her "Princesse Sophie". In the book, once Sir Leigh Teabing reveals the truth of the Holy Grail, Sophie briefly considers this possibility, but Langdon quashes it quickly, stating her surname, and her grandfather's (who is biologically hers in this telling), are not Merovingian.
Other actresses considered for the role of Sophie include Julie Delpy, Kate Beckinsale, Sophie Marceau, Virginie Ledoyen, Judith Godrèche and Linda Hardy.
