Die unsichtbare Front - Der Krieg der Geheimdienste im geteilten Berlin

Armed with information from numerous interviews, access to previously secret documents (many reproduced in the book), extensive research, and their own recollections, the authors roam the existing Cold War literature, correcting lies and false conclusions, putting rumors to rest, and exposing ignorance--in short, setting the record straight. They provide definitive accounts of many key episodes, including the double defection of Otto John, the head of West German counterespionage, and the famous tunnel incident of 1955-56, in which an American tunnel into the Soviet sector was exposed by a highly placed informant and then "discovered" in an elaborate ploy to protect the agent. Battleground Berlin is a remarkable amalgam. It is a fascinating, sometimes gripping spy story, complete with safe houses, forged identities, double agents, and street-corner rendezvous; it is also a scrupulously researched piece of historical scholarship and analysis.
