Each of the "unusual investigations" in this book is an expedition into an unfamiliar world - a world of secrets, lies and double lives. Entering this world, Ron Rosenbaum takes a revealing and provocative look at the unsolved mysteries that have fascinated the public over the past quarter century. "Oswald's Ghost" is the journey into the mind of the alleged assassin of JFK that goes beyond "Did he do it?" to "Who was he?". "The Mysterious Murder of JFK's Mistress" explores the secret life and officially unsolved death of Mary Meyer. "The Last Secrets of Skull and Bones" takes us into the basement crypt of a most secret society and explains why George Bush, it is said, lay naked in a coffin there and talked about his sex life.
