Ghost Tour

Going to be in Rome Mar- 14-19. Any good ghost tours?

Good = I'm not crazy. I don't believe in ghosts or strange orbs. I enjoy a tour that explores the plagues that wiped out communities and changed the direction of the city... the fire that burned out neighborhoods and opened up the building of entirely new parts of the city... the scandals of important leaders that turned out horrific and changed the course of history... the funny and bawdy tale of an innkeeper. Anyone know of a tour with that kind of content?
