Why and how was Archduke Franz Ferdinand assassinated in Sarajevo in June 1914?  Who were the plotters?  Why did they target the archduke?  What did they hope to accomplish?  Did the Austrians deplore or welcome the tragedy?  And how did the murder end up triggering "the war to end all wars?"  Geoffrey Wawro, author of A Mad Catastrophe:  The Outbreak of World War I and the Collapse of the Habsburg Empire, will take a deep dive into the Sarajevo plot and its aftermath.
