Symbologist Robert Langdon investigates a murder in Paris. Near the body is a riddle leading to clues hidden in works by Leonardo da Vinci. He joins forces with Cryptologist Sophie Neveu. They learn the victim was a member of the Priory of Sion, a secret society which included da Vinci. The victim sacrificed himself to protect the location of the Holy Grail, hidden for centuries. Langdon and Neveu match wits with an operative of Opus Dei — a Vatican-sanctioned Catholic sect plotting to seize the Grail. But what if the Grail wasn’t a thing but a person? Mary Magdalene, married to Jesus. What if the Merovingian Kings of France are of their bloodline, with descendants of Jesus alive today? I’m no fan of books where characters run about frantically, but this one is well written, a good read and the clues clever. It’s been denounced as an attack on the Catholic Church and criticized for historical and scientific errors, but it does prove Mary Magdalene was never a whore. Ever. Beware religious revisionism!
