When celebrated Harvard symbologist Robert Langdon is summoned to the Lincoln Memorial to analyze a mysterious rune—drawn on a calling card next to the mangled body of the head docent—he discovers evidence of the unthinkable: the resurgence of the ancient cult of the Inquifori, 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 Inquifori appears at the National Gallery of Art to deliver a sinister ultimatum: Turn over the archbishop, or one cherub will disappear from the Sistine Chapel every day. With the countdown under way, Langdon joins forces with the statuesque and charming 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 300-year-old trail through Washington's most venerable churches and historic statues, pursued by a Romanian 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.
I always knew those Boy Scouts were up to no good.
