Report repeated from 1952 when this title originally appeared. It is now being published as a virtually new book by a different publisher. Its current interest should not have staled in the more than ten year interval. ""A highly intelligent introduction to the three atomic spies, Allan Nunn May, Klaus Fuchs and Doctor Bruno Pontecervo, which is not just an airing of the facts in their cases- fascinating as they are, but an inquiry into the moral content of their treason, the political climate which prompted it, and the concept of loyalty and freedom such betrayal jeopardized. An exciting interrogation into character and conduct, handled with style and a speculative thoughtfulness"".
