Without taking sides in the debate, Krulos joins these believers in the field, exploring haunted houses, trekking through creepy forests, and scanning skies and lakes as they collect data on the unknown poltergeists, chupacabras, Skunk Apes (Bigfoot’s stinky cousins), and West Virginia’s Mothman. Along the way, he meets a diverse cast of characters—true believers, skeptics, and hoaxers—from the credible to the quirky, and has a couple of hair-raising encounters that make him second-guess his own beliefs.
