A Rouge Mossad agent goes to Paraguay with the purpose of assassinating a Dr. Grigori - a Josef Mengele analogue. There is a lot of back and forth, near misses, and complications which keep hunter from prey. And everything ends in a twist that I did not see coming, thought whether it's satisfying is open to debate. The most interesting parts focus on Dr. Grigori, his life in Paraguay, his unrepentant love of the Nazi beliefs, his whining about being a victim. If ever there was a character who deserved to die, then it was him. We see the corruption of the country which harbored the Nazis, the shifting international political climate which made it difficult for escaped Nazis to be captured, and the abject poverty of the countryside which was taken advantage of by escaped monsters. There are some bizarre scenes in the book, the weirdest one being the Nazi beauty pageant, and some might not be interested in the end. I know several people who have abandoned this book, but I stuck with it to the end and am happy I did. Some claim its boring and I have to disagree, but it does take its time. So if you read this book be prepared for that.
