You are lead, step-by-step, through a series of historical events depicting each peace of the puzzle. This "mystery-drama" unfolds very neatly before your eyes. The intricacies are very well explained and documented which is not only entertaining but draws you into the mystery even more. We sometimes believe that we (current civilization) are "smarter" or "better" because time and experience and technology is on our side. But by the end of this unsolved mystery, I think you will come to the conclusion I did that some of our ancestors are laughing their putookies off at us. Enjoy.
