A modern-day pathologically greedy mega-billionaire races to resurrect the fascist 1934 Business Plot to take-over America, and destroy a long-hidden Da Vinci secret that, if revealed, would stop him. A mysterious assassin murders the Italian Ambassador in his Washington D.C. Embassy at midnight. Before the Ambassador died, he sent a cryptic email containing hidden clues about an amazing secret spanning 2,400 years, from the assassinations of Ancient Rome's beloved Gracchus Brothers, to Christ's crucifixion, to the Renaissance Medici's torture of Machiavelli, to the American slave trade, to the Crash of 1929, to the right-wing Business Plot to overthrow Franklin Roosevelt, to today's oligarchs.. The clues lead Smithsonian expert Joe Richmond through national landmarks in Washington D.C. and New York City, in a race against time to find the key before sinister forces can destroy it forever. And solving the clues requires Leonardo da Vinci's 'Saper Vedere' or 'knowing how to see.' A wickedly smart epic thriller that reveals surprises in art, philosophy, history, religion, race, politics and wealth that will challenge you at every turn.
