Adapted from Decoded, Meltzer’s hit show on the annals network, History Decoded explores interesting, unexplained questions. Is usually Fort Knox empty? Why was Hitler so intent on recording the Roman ‘Spear of Destiny’? What’s the federal government hiding in Region 51? Where do the Confederacy’s $19 million in silver and gold go by the end from the Civil Battle? And did Lee Harvey Oswald actually act by itself? Meltzer sifts through the data; weighs competing ideas; separates what we realize to be accurate with what’s still-and maybe forever-unproved or unprovable; and in the end, decodes the mystery, coming to the probably solution. On the way we meet Freemasons, Rosicrucians, Nazi propagandists, and the real DB Cooper.
