Meanwhile, German intelligence, convinced of Klementyna Mankowska's pro-German sentiments, selected her as a potential agent. In June 1941 she started a new job, based in Berlin and working at the Foreign Ministry. It was the first stage in her training. While she was in Berlin she remembered a card that had been delivered for her attention a few months earlier care of her coursin Teresa Łubieńska. Harold von Hoepfner was still alive and he was in town. At dinner, with the same casual boasting that he had employed to give her advance notice of the French invasion in May 1940, he openly talked of his imminent posting as part of the vast army that would shortly be invading the Soviet Union. Mankowska had been welcomed into the Hoepfner family's Berlin apartment as a longstanding family friend. It was important, von Hoepfner, pointed out, that the invasion of Russia should be launched soon so that they did not get caught out by the Russian winter like Napoleon. Later the name of Rudolf "Dolf" von Scheliha came up in conversation. Von Scheliha had worked as a German diplomat in the Warsaw embassy between 1932 and 1939.
