Dan Stone’s The Holocaust: An Unfinished History is a book that is difficult to describe; indeed one might say that it is two books in one, a joining of scholarship and screed. One of these books, which comprises most of the pages of the volume, is an eloquent, invaluable, and heartbreaking history of the Holocaust that emphasizes often overlooked aspects of this utterly evil event. The second is Stone’s application of his own research to the political world of the present, to those he sees as the heirs of the anti-Semites of yesteryear, and here his writing becomes suddenly one-sided.
