I was disappointed in this book. Its title is a misnomer. It should have been called The White City: The Fair that Changed America...and at the same time there was a serial killer in Chicago. 
 The author seems to be writing two books - 1 about the serial killer H.H. Holmes and one about the Chicago World's Fair of 1893. He doesn't do a very good job of intertwining the two stories. He should have chosen one or the other, and since he seemed to favor the story of the architect of the fair, he should have stuck with that. 
 If you like architecture and it's lingo, read this. If you're looking for a true-crime novel, skip it.
