The Robert Langdon Series
Dan Brown originally started his series of book with Harvard professor Robert Langdon in Angels and Demons, although The Da Vinci Code gave fame to the character. The book's success among the audience and the subsequent controversy it created convinced Dan Brown to write more about the Symbologist (a fictitious academic field of study) and his puzzle-solving adventures.
Angels and Demons - When world-renowned Harvard symbologist Robert Langdon is summoned to a Swiss research facility to analyze a mysterious symbol — seared into the chest of a murdered physicist — he discovers evidence of the unimaginable: the resurgence of an ancient secret brotherhood known as the Illuminati… the most powerful underground organization ever to walk the earth. The Illuminati has surfaced from the shadows to carry out the final phase of its legendary vendetta against its most hated enemy… the Catholic Church.
The Da Vinci Code - Robert Langdon is in Paris to give a lecture. At the reception that follows, he is scheduled to meet with a revered curator from the world-famous Louvre museum. But the curator never shows up and Langdon is told that the curator has been found dead that night. Thus begins a race against time, as Robert Langdon becomes a suspect and, with the help of French cryptologist Sophie Neveu, must decipher a mystifying trail of clues to save an ancient truth or end up themselves as collateral damage.
The Lost Symbol - Robert Langdon is called to deliver a lecture in the U.S. Capitol Building. Within minutes of his arrival, a disturbing object–artfully encoded with five symbols–is discovered. Langdon recognizes the object as an ancient invitation to a long-lost world of esoteric wisdom. When Langdon’s beloved mentor, Peter Solomon is brutally kidnapped, Langdon realizes his only hope is instantly plunged into a clandestine world of Masonic secrets and hidden history dragging him toward a single, inconceivable truth.
Inferno - In the heart of Italy, Robert Langdon is drawn into a harrowing world centered on one of history’s most enduring and mysterious literary masterpieces . . . Dante’s Inferno. Against this backdrop, Langdon battles a chilling adversary and grapples with an ingenious riddle that pulls him into a landscape of classic art, secret passageways, and futuristic science. Drawing from Dante’s dark epic poem, Langdon races to find answers and decide whom to trust . . . before the world is irrevocably altered.
Origin - Robert Langdon arrives at the ultramodern Guggenheim Museum Bilbao to attend a major announcement—the unveiling of a discovery that “will change the face of science forever.” The evening’s host is Edmond Kirsch, a forty-year-old billionaire and futurist whose dazzling high-tech inventions and audacious predictions have made him a renowned global figure. Kirsch is about to reveal an astonishing breakthrough that will answer two of the fundamental questions of human existence.
