On the pages of the book comes to life the image of Friedrich Wilhelm Canaris - a man of mystery, the head of the Abwehr in 1935-1944, who created a wide spy network that covered the countries of Europe, Asia, America, Africa. Moving away from the common image of Canaris, a reactionary, the author shows how, gradually realizing the crime of the Nazi regime, Canaris takes the path of supporting a conspiracy drawn up by a group of Wehrmacht officers in order to eliminate Hitler. The best of the books about Canaris for the first time becomes the property of the Russian readership.
