Robert Langdon, the Harvard symbologist, received a call from his former mentor and close friend, Peter Solomon, early one morning. Could he please give a lecture that evening to replace a speaker who was suddenly taken ill? Langdon couldn’t possible deny the request of a dear old friend. So he boarded the private jet Solomon had waiting for him to Washington.
When he arrived at the National Statutory Hall, it was empty. There was no one there, no audience. It turned out that the person Langdon spoke with earlier that morning was not Solomon’s personal assistant. He spoke to a maniac who had kidnapped Solomon and now Langdon had to do his bidding if he wanted to save his friend’s life.
Langdon’s quest was to find the Mason’s ancient pyramid and solve a series of riddles to uncover a long lost treasure, a secret ancient wisdom, buried somewhere in Washington. The Masons had been guarding the secret for generations, waiting for the moment mankind is able to comprehend the powerful knowledge that will take human civilization to a new level.
