3.5/5 stars. I feel bad taking away one and a half stars knowing how much research Erik Larson put into this book but there were parts that were soooo slow. 
 I found the story of both the Chicago World Fair and H.H. Holmes to be fascinating. The last 1/4th of the book was absolute 5 out of 5 stars! 
 However the setup and the length sections about the architecture of the fair went on for too long for my liking. I have a trip to Chicago planned for later this year and The Devil in the White City has definitely added some items to my sightseeing list!
