On episode 32—released on the 32nd of the month—Charles talks to Gareth Russell, who wrote a book about the Titanic (Ship of Dreams: The Sinking of the Titanic and the End of the Edwardian Era) and who, a couple of years ago, was invited to take a trip on the Titan submersible that sunk this week. Among the topics Charles and Gareth discuss are why the Titanic continues to command such interest, whose fault its sinking was, when the conspiracy theories started, and if its ethical to go down to what is, in effect, a mass grave.
