Everyone loves a good mystery. And the only thing people love more than a good mystery? A real mystery. History Decoded, based on the popular History Channel show Brad Meltzer's Decoded, explores history's ten greatest conspiracies. In each chapter, a famous historical mystery will be explored in depth - like 'Was Lincoln's Assassin Apprehended?' Unanswered Questions of the Kennedy Assassination, 'The Spear of Destiny', 'Lost Confederate Gold', UFO's' and 'Da Vinci' among others. Sometimes the mystery proves to be true, sometimes a hoax-and sometimes not quite provable. Each chapter is profusely illustrated in colour and includes an envelope containing removable facsimile documents (like John Wilkes Booth's alleged unsigned will!)-all keys to unravelling the mystery in question.
