I have read every book in the "killing" series, and was not disappointed with Bill and Martin's latest offering. This book was fascinating and had enough new detail to keep me riveted to every page. I liked the way the authors wrote about different war criminals to weave the "killing" of the SS as a theme for the book. It made sense, particularly capping the book with the shock that Otto Skorzeny had worked for Israel's Mossad years after World War II. If you know anything about Skorzeny that would be a big indicator that the SS were dead. I don't know if this is the best of the "killing" series, as I am very partial to "Killing Lincoln," and "Killing Kennedy," but it is definitely in the top three of the seven.I will warn you. Once you start reading this book, you will have a hard time putting it down. Very well done!
