Episode #21: A Conversation with Catriona McPherson. A major award winning author of more than 30 novels, McPherson talks about how the Edinburgh-born writer became an author of California-based humorous mysteries with the Last Ditch series. We also talk about her 15-book Dandy Gilver series set in Scotland of the 1920s and ’30s, and her standalone psychological thrillers. The fifth book in her Last Ditch series, “Scot in a Trap,” will be published in December.
