Essentially, either Gilles De Rais was one of the first serial killers, and a quite egregious one by the standards of any period of history, or it was a frame job and land grab by the church and other megalomaniacs to conveniently take advantage of a pretty stupid rich general who was just trying to finish his damn play. **The episode itself has 42% less run-on sentences.
