Murder, Magic, and Madness at the Fair That Changed America. For my taste it would have been two books. The magic was the absolutely fascinating story of the planning, building and operation of the fair itself. What a revelation of an new world at its outset! That is the birth of modern America.
The second book would have been the story of as mass murderer and all the incumbent details. No thank you. If I wanted to learn more about insane people who do horrible things to there fellow human beings I could just as easily turn on my television and watch the evening news....:(
