"Johnson's book is easily the best introduction to the frequently misunderstood world of counterintelligence. This classic work, packed with timeless principles and highly readable, is a vital addition to the bookshelf of any intelligence professional." -- David N. Edger, former CIA operations officer, and visiting professor, University of Oklahoma
"Counterintelligence, without question, is the toughest job in the world of spying. And, historically, we haven't been as good at it as we should. That needs to change. One glaring shortcoming in recent years has been the lack of a good treatise on the 'art' of counterintelligence. William Johnson's book, which has been out of print for years, fills that gap. He gets it right. Only a respected CI pro like [Johnson] could have described so clearly our arcane business of dangles, doubles, defectors, and deception. Thwarting Enemies at Home and Abroad will not only be a fascinating read for the general public but will also serve as a text for a whole new generation of CI trainees." -- James M. Olson, former chief of CIA counterintelligence and author of Fair Play: The Moral Dilemmas of Spying
