" Eichmann, seeing this would only go more poorly, asked Wisliceny for his opinion on the matter, subjecting himself to an overlong bit of wind and bluster backed by an utter absence of knowledge. He listened as he forever did, storing away bits for future use and keeping to himself his own advantages. This was his job, to listen and nod while others talked, and he was very good at it. He routinely shucked his uniform for street clothes in order to infiltrate and more closely observe Berlin’s Zionist groups. He’d developed a cadre of informers. He gathered information from the Jewish press. Reported on Agudath Israel. Quietly kept denunciation files. Directed arrests. Helped with Gestapo interrogations. "
