That's right. We've found a way to combine two of our favorite things into one episode: Ghosts and true crime! In the early 1800s, the London borough Hammersmith was being terrorized by a ghost. Several people were attacked and people were scared to  come out of their homes.  Concerned groups of citizens would search at night for the Hammersmith ghost, hoping to put a stop to the terror. But what happened instead would set in motion a trial unlike any that people had seen before, setting a legal precedent in the U.K. regarding self defense.
