This should have been written as two separate tales. The politics, mystery, creativity and drive to stage this World's Fair during the industrial revolution was a tale unto itself. The unpleasant story of the serial killer would be suited to those who want to read murder mysteries and tales of gore. All in all it was a good book, historically interesting. Unfortunately, my copy was missing about twenty-five pages that included the first murders in the "castle" and the opening of the World's Fair.
