Erik Larson, The Devil in the White City

Erik Larson, The Devil in the White City. I thought it was a novel about the world's fair in Chicago, judging by the cover, but instead it was a novelized non-fiction account of a disgusting and ingenious serial murderer operating in Chicago during the world's fair. Maybe it was good, and it was certainly fascinating, but I wanted to bathe in sand and bleach and remove my mind after reading.
