Dan Brown is a highly successful American author known for his suspenseful thriller novels that often incorporate elements of history, art, symbolism, and cryptography.One of his most famous and influential works is The Da Vinci Code (2003).Tzvetan Todorov is a Bulgarian-French literary theorist, philosopher, and cultural critic known for his influential contributions to the fields of literary theory, semiotics, and structuralism. He played a significant role in shaping the way we analyze narratives and understand the underlying structures and meanings within them. Brown’s The Da Vinci Code has been analyzed from different perspective but not Todorov’s structuralist theory. This research argues that Brown’s characters deploy ambiguity and element of fantastic to create suspense. It focuses on the use of hesitation and uncertainty as a tool of fantastic to create ambiguity in Brown's novel through Todorov's theory of narrative ambiguity. The use of multiple narrators, conflicting accounts of events, and references to real historical figures and events create a narrative that blurs the line between fact and fiction. The ambiguity in the narrative serves as a way for Brown to explore complex themes related to religion, power, and history without taking a definitive stance. By leaving the truth open to interpretation, Brown encourages readers to engage with the narrative on a deeper level, prompting them to question their own assumptions and beliefs.
