Holocaust fiction of the crudest, most amateurish and exploitative sort--as non-Jewish survivor Paul Hammer (his parents were anti-Nazis) comes face to face, 40 years later, with the Jewish kapo (guard) who beat his mother to death. It just so happens, you see, that Hammer's psychiatrist-son is about to marry the granddaughter of multi-billionaire Louis Luckstone, a Jewish survivor; and Hammer immediately recognizes Luckstone as Ludwig Gluckstein, a ruthless kapo at Treblinka. Determined to expose Luckstone, Hammer goes searching in Europe for surviving witnesses--a noble SS guard, a crippled Jewish woman who was forced into demeaning sex-acts, and an infamous SS officer (""one of the most diabolically brutal, inhuman monsters ever to walk the Earth""). Meanwhile, however, Luckstone's CIA/White House connections have unleashed a horde of assassins on Hammer--who manage to kill his new love (a bomb in London) and that noble SS man. And eventually, after lurid/graphic deathcamp flashbacks and hackneyed ponderings on Holocaust horrors, there's a showdown between the survivor/accusers and the evil Luckstone--involving debates on Holocaust guilt (Hammer has some too), speeches about ""absolute moral truth,"" and a cartoon-melodrama windup. Well-meaning, perhaps, but a plodding, shrill thriller/sermon for the most part--with clumsy plot-exposition, dreadful dialogue, and implausible characters; far better treatment of all the issues here abound, in both fiction and nonfiction.
