Chloe Hooper and Susan Orlean join Matthew Condon to share their insights into the dark logic of arson, and how they reconciled confusion and culpability in piecing together portraits of maddeningly elusive subjects. Chloe’s The Arsonist investigates the bullied loner who lit two of the Black Saturday fires. Susan’s The Library Book examines the prime suspect of the devastating 1986 Los Angeles Public Library fire, a handsome drifter who yearned for stardom.
