Here's a breakdown of the points of view:
* Robert Langdon: The primary focus of the story. We see the world through his eyes, understanding his thoughts, feelings, and actions.
* Sophie Neveu: We get a glimpse into Sophie's thoughts and feelings, particularly her connection to the Priory of Sion and her relationship with Langdon.
* Sir Leigh Teabing: The story offers insights into Teabing's motives and knowledge, but we don't see the world entirely through his eyes.
This third-person limited perspective allows Dan Brown:
* To control the information: He can selectively reveal information to the reader, creating suspense and intrigue.
* To highlight Langdon's intellectual journey: We see his thought processes and his struggle to decipher the clues, making him a more relatable protagonist.
* To create a sense of mystery: By limiting the reader's perspective, Brown maintains a sense of intrigue and keeps the story moving forward.
While the narrative primarily follows Langdon's perspective, the occasional shift to Sophie's point of view adds another layer of complexity and provides the reader with a different emotional perspective on the events unfolding.
