The book is based on documentary materials and memoirs of direct participants in the events. You will learn about how the development of the Northern Sea Route began; why everyone but the Soviet Union knew about the outbreak of World War II; what the Nazis did in the Barents Sea and where the uninvited guests came from in the Soviet Arctic; who are the ocean "werewolves" and what they traded on the routes of the Northern Sea Route; as well as about the Arctic odyssey of captain-tsur-zee Robert Eissen and the last path of the Comet raider. The Soviet Arctic has been keeping its secrets securely covered by ice for more than 60 years. But the time has come to declassify archival documents, which allows us to take a fresh look at the history of the war years.
