The book tells about the attempt of three intelligence services - the KGB, the CIA and the West German BND - to gain access to the card index of the agent archives of the GDR MGB. The story takes place between 1989 and 1990. in Germany. The author at that time worked in Berlin as a correspondent for the Trud newspaper, was an eyewitness to the events described and personally knew some of their participants. The main attention is paid to the CIA’s attempts to identify a “mole” in its ranks, through whose fault the United States lost a number of agents in the most important scientific, diplomatic and intelligence structures of the USSR. One of the ways was access to the foreign intelligence file of the GDR MGB, since Langley had information about close cooperation between the foreign intelligence services of the USSR KGB and the GDR MGB. This operation was codenamed "Rose Tree", and its details are still classified. In order to implement it, the recruitment of the former head of the foreign intelligence service of the GDR, Markus Wolf, was carried out. We are talking about the international life of the period when events unfold: the collapse of the USSR, the reunification of Germany, the activities of Main Directorate “A” (foreign intelligence of the GDR MGB), associated with an attempt to preserve its structure and personnel, and describes the methods of work of the special services at that time. The book is based on the memoirs of leading intelligence officers of that time in the USSR, East and West Germany, the USA, publications in German and American publications, as well as the author’s personal observations. The main characters, Soviet KGB officer Alexander and CIA agent Jim, are real characters who are no longer alive...
