Hitler's example shows: few people have the gift of foresight, but the cost of error can be excessively high. The author studied dozens of memoirs of people who lived in Germany or visited the country in the thirties of the last century: diplomats, military men, journalists, writers, artists, athletes, businessmen, tourists. They saw the violence of the "party in power" over political opponents; repression of national minorities, homosexuals, social democrats and everyone who did not keep up with the totalitarian state pouring with the juice of hatred.
