The Paul Marcus Trilogy

When former CIA code breaker Paul Marcus receives the call, he thinks it's a hoax. He's asked to analyze a cache of papers found locked in an old trunk. They were the last manuscripts written by Isaac Newton. Using Newton's math and notes, Marcus begins to see a pattern leading to a prophecy so frightening, to reveal it will change world events.

When an encrypted letter written by Thomas Jefferson is found hidden in the attic of an old farmhouse in Virginia, the information could offer a clue as to who killed a US Special Forces soldier 220 years after the letter was written. Paul Marcus, who five years earlier broke an encrypted paper written by Isaac Newton, is tasked to see if he can unlock the secret Jefferson had originally meant for only one person. More than two centuries later, a relative of the first man to declare war on America - a nemesis of Thomas Jefferson - vows to fill a family vendetta.
