Once We Were Bothers by Ronald H. Balson

As Hitler restricted, contained, and murdered the citizens of Germany, young Otto’s parents leave him with Ben’s family.  But eventually Ben’s Jewish family is on the hit list and Ben’s father encourages Otto to go back with his parents who work for the Hitler regime.  Ben’s family's struggle to survive is the meat of the plot.  Ben survives against all odds, moves to the U. S. and lives a quiet life for many years.  But then he recognizes who he believes to be this "brother," living and wealthy beyond belief. Ben tries to expose Otto. But is this newly found ‘Elliot’ really long lost Otto?  Wealth buy silencers. What lawyer would touch this case and be threatened by the repercussions?  Great book.  9 out of 10.
