Devil in the White City by Erik Larson 2004

[El Dingo]

The age of the book is an interesting point. I bought a 2004 book at a mass-market store with maybe 75 to 100 fiction titles in 2012. Another forum I read (Reddit) had a post about H.H.Holmes possibly because he was featured on a "Supernatural" episode.

Let's see if the media saturation plays out and the Holmes + 1893 Worlds Fair takes over the History Channel and pop culture for no reason whatsoever.
