Louise Penny's immersive murder mysteries, set in her home province of Quebec, have drawn a large and loyal fan base. But writing came as a second career for the New York Times bestselling author, a former broadcaster who faced a debilitating struggle with alcoholism before taking up writing fiction. Martha Teichner visits Penny in the small town of Knowlton, which could be a stand-in for her fictional town of Three Pines, where too often there is murder afoot. Air Date: Jul 9, 2017
