Here is a review by Ryan: https://www.goodreads.com/review/show/1985669792
Although it has some interesting information in it, Klop suffers from two major flaws.
The first is the flow of the story. it follows a generally linear technique beginjngnwith Klop and his wife’s parents and follows through until there deaths. however, it jumps around in the story telling bits and pieces of the narrative and never strongly connects the pieces.
The second, and more important problem, is that it isn’t really about Klop. It’s more about the events that happen around Klop. You never really get a true sense of the man. Once the author is done describing him physical and gives you an idea that he is a womanizer and a defender of freedom, you never learn much else. There is no great depth that you learn about anyone in the telling of this story.
So, although there are some interesting tidbits about how the Human and Counterintellignecenwar was fought during World War 2 and the early stages of the Cold War, there is not enough of the story and not enough of the human struggle of Klop to make this more than a good book.
