I could not be Captain Cook. There was no new island to discover. No lee shore to step upon for the first time. No “Giants of Patagonia” to entice the adventurous to a mythic land in which one might discover Professor Challenger’s “Lost World” and find dinosaurs on an isolated escarpment. But world mysteries abounded. They captured the minds of generations. Yet none were ever solved. Hype and Hyperbole had obscured them for decades. What was the truth behind them? Who were the villains of famous crime sprees who had outwitted their pursuers? The principles of investigative inquiry could be seriously directed beyond biographies of Napoleon and the great events of the march of history. I unintentionally became an ‘investigative historian’ of the world’s most popular mysteries and unsolved crime cases.
