Where was the piped piper set?

I assume you mean Pied Piper, a reference to his unusual striped and say, Piebald costume. The story takes place in the (real) German city of Hamelin in the Middle Ages. it is very unusual as it involves abduction of children and the Bad Guy is the focal character ( rather like Dracula or Frankenstein"s monster) He seems to get away with his misdeeds, also rare in Fairy Tales. I never did like it. Now, what if some nut hijacked a school bus, it has happened. In a very loose sense the science-fiction film The Amazing Collossal man is paralell, in one scene he grabbed ahold of a school bus filled with screaming kids ... Evil men are nothing new.
