The manuscript of the book was written by Bogdan Radica during his time in exile. It was finally published in 1974 in Barcelona and Munich, by the emigrant publishing house Hrvatska revija. He also collected his own articles published in the American press, his memoirs from Croatia and Yugoslavia covering the period from November 1944 to May 1946, and his notes from Izgnanički dnevnik (Exile Diary) in which he had made note on his journey from Italy and America. After the Croatian Spring in 1971, following conversations between the editor-in-chief, Vinko Nikolić and Radica in New York, they both decided to print the book. Radica decided to do that in order to explain what are the roots of “the newest Croatian catastrophe” in Tito’s Yugoslavia. In the book, he pointed out the fear and repression of the Communist revolution in Croatia.

Croatia survived the strongest level of repression because it demonstrated much more resistance than the other Yugoslav regions. In the book, Radica describes the situation during those revolutionary days in Zagreb and his hometown Split. He described the killings and jailing of people in those cities, among whom there were many respectable people from public life. Hence, he coined the phrase “great fear in Croatia” to describe the revolutionary terror. When he decided to flee Croatia and Yugoslavia, he sent his wife a telegram importantly titled “I have left Tito's paradise forever.”
