Burke McCarty sets out a complex alternative theory regarding the assassination of President Abraham Lincoln, namely the notion that the event was orchestrated by shadowy religious powers. McCarty gathers and presents correspondences and other documents; together these offer an alternate explanation for Lincoln's heinous murder. He alleges that a Treaty in Verona in 1822 was the start of a plot to kill an American President, a plot whose pieces would gradually fall into place in the four decades which followed. McCarty alleges involvement by the Pope and the Catholic church, plus other clandestine figures, pointing to what he considers coded references in letters. Modern historians and scholars consider alternative theories behind the death of President Lincoln as spurious conspiracy. The overwhelming evidence remains that John Wilkes Booth, a vain and agitated man with a craving for notoriety, acted alone in his scheme to murder Abraham Lincoln as the President watched a performance at Ford's Theater.
