Today, another episode from the Revisionist History Live universe. It's an old fashioned lecture, recorded at the New Orleans Book Festival at Tulane University. Malcolm talks about a totally real thing he made up—a taxonomy of the modern mystery story—with a focus on murder mysteries and police procedurals. From Dragnet, to John Grisham, to Sherlock Holmes, it's all in there...and all connected to how we view real policing.
