PositiveThe Washington TimesForemost among those who solved the mysteries of foreign code was a remarkable American couple, Elizebeth and William Friedman. Elizebeth’s story is told in highly readable prose by Jason Fagone, who makes the complicated subject of codes comprehensible (more or less) to an ignorant layman ... Given that William was the subject of a 1976 biography, Mr. Fagone’s focus is on Elizebeth, whose papers, along with those of her husband, are at the George C. Marshall library at Virginia Military Institute ... A complicated read, to be sure, but a worthwhile one.
