The world’s oldest family of high-profile assassins, the Firefaxes, have been killing off dignitaries—and being well-compensated to do so—for centuries. The family is thrown into turmoil by their patriarch’s death and the return of their cunning, cruel prodigal, Murdoch. With their father dead, Murdoch is the only one who knows where the Firefax wealth is, kept on a secret island. But two competing intelligence networks in the American Revolution are bent on tracking down the legendary treasure to end the war, whatever the cost. However, these spy networks may have met their match in this wily, dysfunctional family of killers.
