AL BUEN ENTENDEDOR... . Esta novela es a la literatura lo que la planta nuclear de Chernobyl es al medio ambiente

Judson would be a demagogue, if he could get your attention. . I would have given this no stars if it were an option.     The first 20 pages of this book bored and insulted me. Judson drones on about every fraud known to mankind, but only occasionally scientific fraud. He seems to hope that if we hear enough examples of fraud in the world, we will get fired up and join him in a lynching.     His tone is condescending and assumes that you already agree with him. This is not the type of academician that you could hope to have a meaningful conversation with. He laces his information with references to "the epidemic" of fraud and nobody being "immune" to it, as if by the weight of these descriptive terms you will be swept into his inevitably correct conclusions. I suspect that Judson would have presented a more objective book if he had more worthwhile information to offer.

The Final chapter...or is it? . This is a book you expected Massie to write.....since Nicholas & Alexandra was written in (I think) 1969, an update since 1991 was critical. It gives you an idea what was being discovered in DNA research and proving the bones found were who they were. Its a book a Romanov observer should have, or at least read to glean the information from. Worth it, for sure.
