A great book by Daniel Silva. Easily my favorite so far in the Gabriel Allon series. This book is basically about hunting down a Nazi SS officer who is alive and thriving in Austria in our current day. The parts of the book that really stick out to the reader are the flashbacks to the World War II period and the suffering that some of the Jewish people had to go through as a part of the "Final Solution." Very well done. I enjoyed it so much I am going to read more on World War II and will likely not wait to buy the next book in the series.
