Agent thriller with political empathy

Follet takes the reader into the political situation in Europe and the Middle East in the 60s in the last century. And I was able, as it reflects the respective political camps and positions with a human eye, what to get the reader to think.
The Acktionspannung in this crime builds up gradually, keeping her bow to the very end. Even though I had already guessed how it turns out, I had put the book aside and am reluctant to turn left to the last page.
Anyway, the story gives an idea that the world peace well sometimes stand in the times of the Cold War on a knife edge.
