First, we run down the "mysterious monoliths" found so far, and get a special call out to Louie Raffloer, the blacksmith who created a much more true-to-Kubrick monolith back in 2001. For our main segment, we are joined by Dr. Leo Igwe, who tells of the latest witchcraft accusations and attacks he and his organization have fought against in Africa. Dr. Igwe delves into some of the factors that cause this dangerous type of superstition to run rampant in the region, and lays out steps that Africans, as well as the rest of the world, can take to help end it. Dr. Igwe's goal is to end witchcraft persecution by 2030, and if you wish to support this cause, you can donate at BetterPlace.org (click "English" at bottom right, then search for "Advocacy for Alleged Witches Nigeria.")
