Experts on the subject as well as those slightly less expert have spoken highly of this book. Hagen has written a good, detailed account of certain espionage cases in West Germany since 1945. He has a knack for conveying the essence and feel of these HUMINT collection cases. Conceptually, the author equates the clandestine struggle in Germany with that in Europe as a whole. Practically all cases are those of eastern European services against West Germany or against Allied targets in West Germany. There are good sections on Frenzel, Stashinsky, and Otto John. The weakest chapter, on the Gehlen organization, contains the bulk of the minor errors to be found; the reader should be wary in particular of some accounts of how certain agents were uncovered. The postscript chapter represents Hagen’s view that a two-way flow of information supplied by intelligence services is necessary for a balance between East and West. In the context of the Communist victories recounted, it may be misread as a justification of that massive espionage.
This is a review by the Defense Intelligence School.
A well-recommended book of post-WWII espionage activities in Germany, with discussions on both West and East German espionage operations which convey the nature of the secret clandestine war between competing intelligence services.

An excellent, detailed examination of outstanding cases of espionage in West Germany since 1945, foreword by Sir Kenneth Strong and a postscript essay entitled “Espionage and the Balance of Power” which concludes that “the intelligence services have assumed a new, vital and creative role in world politics. Espionage, after the threat of nuclear war, is today the strongest contributor to the maintenance of peace in the world.”
