At the service of the ideological enemy of one’s country. Bulgarians collaborating with the Soviet intelligence during World War II

The research is dedicated to two Bulgarians of high social standing who became associates of the Soviet intelligence in the years of World War II. The author tries to answer the question why they made such a choice, despite the fact that on March 1, 1941, Bulgaria joined the Tripartite Pact and became an ally of Nazi Germany. In 1942 and 1943, both – gen. Vladimir Zaimov and Dr. Alexander Peev, were discovered, convicted, and executed, which makes the search for the reasons why they made this choice particularly important.
