The Thousand Year Man

A man living in Dallas, Texas repeatedly has a dream of a book that is in a cave. He wonders if it exists. This winding tale leads him to find that not only DOES it exist, but the Vatican has been hiding this book for over 85 years. His wife's friend is a Catholic priest who she asks for help. When he uses his church computer to inquire on this bookname, he is presented with a message "Possible match in the secured section." This starts a chain reaction of "Who knows? What do they know? How do they know? and ultimately leads to Rome. Once there he has a conversation with the powerful man in white. They have it. They have had it for a long time. They still can't get near it, they can't open it, they can't read it, but this Texan can. Now they want to know why?
