Adolf Hitler was deeply into the occult and even established a Nazi organisation called the Ahnenerbe, with a secret mission to track down and confiscate holy relics. Hosted by film and television star Lance Reddick, ‘Book of Secrets’ is a series that asks the question: ‘What if there is a book that serves as a repository for America’s most closely guarded secrets?’ The USA’s story can be told in many ways. While much of the history of the country is well documented and widely available, there is another deeper history, one that has been shrouded in secrecy and hidden from public view.
