But he forgets that the adventure began because Sophie decided to step in and take Langdon away from Fache, making them fugitives in the first place. After Teabing is revealed as the Teacher, his first thought is how to get Sophie out of the situation, and feeling guilty for taking her to Teabing’s estate in the first place. In the book, he feels responsible for everything they’ve gotten themselves into and feels the need to make it all right again. Langdon feels the responsibility to take care of the people around him. There are several times throughout the book inwhich something will remind him of a lecture he’d given, and he’ll fondly reminisce about his clever discourse. His tendency to know everything also creates a vivid inner monologue, which pulls his attention away from the actions happening around him to a surprising degree. Langdon is trustworthy, and these qualities make Sophie trust him even though he is a completer stranger. He is likeable, capable, and goodhearted. So we can say we listened to Brown’s thoughts through Langdon. Brown’s extensive research into Church history and the machinations of secret societies is given voice in Langdon’s thorough and detailed explications. He serves as a historical tour guide for the story. The police adamantly summons him to the crime scene to help them decipher clues left by the victim at the scene after misunderstanding one of the clues left behind by Sauniere. In this story, he happens to be in Paris when the curator of the Louvre museum is murdered. He seems to be an unintended main character in that the action and adventure of the plot find him, rather than him searching for it. Robert Langdon, Harvard professor of symbology and author of several books on religious symbolism and iconography, is the story’s protagonist. ‘ The Da Vinci Code‘ is the second of the Langdon series, so we get a protagonist whom Brown fans are already familiar with and meet new characters who present a broad spectrum of ideologies that motivate their actions.
