We cover material from chapters 9-12 on this episode, diving deeper in the the strange features within the Great Pyramid, and reading about Chris Dunn's hypothesis on what this ancient structure may actually have been for. Kyle also reads a relevant article about the story of Caliph Al-Mamun who supposedly dug his way into the great pyramid, creating the rough cut tunnel that tourists use today to enter the structure. We still haven't completed the book by the end of this episode, so there will most likely be a part 5.
