Found this book to be a very interesting read on the history of the Chicago's World's Fair as well as the "Devil" himself H.H. Holmes. I wasn't sure I would care for all the history on the planning and construction of the fair. Being an avid reader of true crime I was interested in the serial killer Holmes, but found myself completely wrapped up in the enormous feat of the realization of the Chicago's World's Fair named "The Columbian Exposition". I found myself constantly questioning how they could have ever accomplished this enormous undertaking in such a short time frame. The style of flipping back and forth from the fair to Holmes' story was a great way to combine the two subjects that occurred simultaneously and keep your interest sparked for both subjects.
