About the book: 2010 / On June 28, 1914, in the center of the Bosnian city of Sarajevo, the heir to the Austro-Hungarian throne, Archduke Franz Ferdinand and his wife were killed. The assassination attempt led to a chain of events that a month later plunged all the leading states of the world into a protracted war that buried the old patriarchal Europe. Despite the fact that the details of the assassination of Franz Ferdinand are thoroughly known to researchers, there are a huge number of “blank spots” associated with it. It is still unclear who pushed the “Black Hand”, for what reason minimum security measures were not taken in Sarajevo and, finally, who benefited from disturbing the peace of “old lady Europe”».
