John Dickson's Bullies and Saints is a super-podcast providing excerpts of the book by the same name - a no-holds-barred look at the best and worst of church history.

In this episode, John Dickson takes us to the Crusades and introduces one of the most infamous crusaders of all: Peter the Hermit, a fire and brimstone Christian if ever there was one.
