An ancient code in the monuments of New Orleans. A nefarious cult determined to protect it. A desperate race to uncover the Boy Scouts of America’s darkest secret.

When celebrated Harvard symbologist Robert Langdon is summoned to the French Quarter to analyze a mysterious geometric form—etched into the floor next to the disfigured form of the head docent—he discovers evidence of the unthinkable: the resurgence of the ancient cult of the Trumifori, a secret branch of the Boy Scouts of America that has surfaced from the shadows to carry out its legendary vendetta against its mortal enemy, the Vatican.

Langdon’s worst fears are confirmed when a messenger from the Trumifori appears at Lake Pontchartrain to deliver a fateful ultimatum: Turn over the archbishop, or one cherub will disappear from the Sistine Chapel every day. As the city braces for disaster, Langdon joins forces with the nervy and quick-witted daughter of the murdered docent in a desperate bid to crack the code that will reveal the cult’s secret plan.

Embarking on a frantic hunt, Langdon and his companion follow a 900-year-old trail through New Orleans’s most historic buildings and venerable churches, pursued by a two-handed assassin the cult has sent to thwart them. What they discover threatens to expose a conspiracy that goes all the way back to Davy Crockett and the very founding of the Boy Scouts of America.
