Martin leads a "reach back" episode about Franz Ferdinand and why the Serbs thought he was worth shooting. Shoot a guy in a funny hat, start a war. Damn 1914 was weird. The story includes a juicy sex scandal, so be sure to download and give a listen. 

Although the guys don't mention it by name, perhaps the best and most recent works about Franz Ferdinand is The Assassination of the Archduke: Sarajevo 1914 and the Romance That Changed the World by Greg King and Sue Woolmans from 2014. It's worth checking out.
