Even stretched out with unnecessary flashbacks, this short sequel to The Domino Principle (1975) reads more like an additional chapter or two than a full-fledged suspense novel--as jailbird Roy Tucker, forced to assassinate a former President in Principle, now wreaks vengeance on the schemers who set him up, killed his wife, and tried to kill him too. Eluding assassins in Costa Pica, Tucker eliminates a couple of hit-men, flees to Rio, escapes another trap there, and finally makes it back to the US--where his only real friend becomes the conspiracy's latest victim. So Tucker first blackmails the conspirators (led by the top White House military advisor) into sending him money. Then he lures the top henchman to his hideout, forces him into a full confession, and kills him. And finally, before his own inevitable demise, Tucker assassinates that military mastermind (a grenade at the UN), who had planned--with a sort of Trilateral Commission conspiracy--to take over the Arab oilfields for the West. A rudimentary, slapdash follow-up--without the tension or character-interest of The Domino Principle.
