A pact has been agreed upon between British politicians and leading American colonists for a war of independence to take place that Britain would ultimately lose. In return, the new US would secretly pay an amount to Britain each year that would help support the financing of their navy and military to defend themselves and their Empire against a new French Republic. 

Throughout the coming years this pact had been known to only a select few but this knowledge had contributed to important historical events, including the War of 1812, World War II, and the Kennedy Assassination. Nevertheless, the secret had remained in tact until an innocent couple uncovered a trunk containing letters written between the British politicians and the American colonists that describe certain events that lead to the War of Independence. 

The couple contacted a top museum to have the letters authenticated but this act unwittingly set off a chain of events that caused the death of a junior curator of the museum at the hands of the F.B.I. The couple are then chased by the F.B.I. until their eventual capture when they are taken to Washington. 

The director of the F.B.I. is one of the few people in the know and he provides a brief history of the pact and why it must remain a secret. But it doesn't end there as the couple escapes from the clutches of the F.B.I. only to find themselves in the custody of a group of British S.A.S. operatives. Ultimately, they come face to face with someone even more imposing and intimidating than anyone they have ever met before, and their fate is hanging in the balance.
