Heirs of Cain

Among the former prized military elite of the Vietnam War is a psychopathic killer, Seneca. A highly trained warrior with the finely honed tactics of a commando and a genuine thirst for blood, he's been hired to eliminate the president of the United States and three top Middle Eastern leaders. Only the mysterious Cain, a brilliant and lethal former assassin, can track down his one-time comrade and stop him. Against a ticking clock, Cain must hunt this deranged slayer and destroy him before he ruthlessly murders again.
