Harry Houdini is known for his daring escapes and illusions, but he also had an obsession with debunking spiritualist frauds.

Today, we’re bringing you the first of a three-part series from another Pushkin podcast, Cautionary Tales, about Houdini’s crusade to expose phony mediums, an undertaking that would lead him to the courtroom and put him on a collision course with his close friend Sir Arthur Conan Doyle. Host Tim Harford stops by The Last Archive for a conversation with Ben Naddaff-Hafrey about Tim’s fondness for historical morality tales, the concept of invisible worlds, and the root of Houdini’s anti-spiritualism. You can listen to the rest of the series on Cautionary Tales.
