Once again Erik Larson is an consummate historian. His research is outstanding. I only know of Dodd by name and not much else so this was an eye-opener. Once it again, Larson proves his point that had the US government listened to Dodd as well as others, 6 million lives would have not been lost to the mad men of Hitler and his cronies. Dodd, a very staunch Jeffersonian, wants a different way for the ambassadorship, especially in Europe but once again the old boys club in Washington at this time, fails to listen to him. Larson's research into Dodd's life as well as Martha's, was amazing. Martha's tryst with NKVD operative is especially astounding considering the atmosphere at the time. However, unlike the other two books of Larson's that I have read, this one was much drier. His other two books had a mystery element to them, as both involved a murder (Devil in the White City and Thunderstruck) so this book was harder to get through than the others.
