Through Novosad, Wilhelm acquainted Lidia with the Frenchman who agreed to cooperate with the Ukrainian nationalists and gave Lidia her first task to find German documents for a British pilot who was downed in Austria. Lidia had accomplished it. Eventually from her Wilhelm became informed that to Vienna arrived someone very important from OUN. At first Wilhelm met with him at the Novosad's apartment where he became familiar that the person was called Dmytro-Volodymyr and later also introduced him to Maas. In reality Dmytro-Volodymyr was Myroslav Prokop who was one of leaders of OUN and Ukrainian Main Liberation Council (UHVR).
