The reader will not find stunning stories, exotic adventures or deadly battles under the sign of cloak and dagger in Boris Grigoriev’s “nostalgic Memoirs”. And yet, the author of this book, undoubtedly, managed, based on his own operational experience and the experience of his colleagues, to give the most objective picture of the life of a Soviet intelligence officer in the 60-90s of the 20th century. Traveling “from the back door” through the Scandinavian countries, setting up in stopping along the way to reflect on the problems of the Foreign Intelligence Service, the thoughtful reader, having followed the author to his native shores, will appreciate both the book and the difficult life of a soldier on the invisible front.
