Mercy Street Rewind is a special feature from In The Past Lane, the podcast about history and why it matters. Historian and cultural critic Megan Kate Nelson joins me for a review of each episode of the PBS drama, "Mercy Street."  It's a fun, fast-paced conversation about the Civil War history behind the show, plus our take on its storylines, characters, and whatever else catches our eye. This week we talk about Season 2, Episode 3. Learn more at the show page: http://inthepastlane.com/mercy-street-rewind-season2/
