Radford gives a historical perspective on the role of vampiric creatures in Latin American folklore, as well as that of conspiracy theories (did you know one of the leading beliefs about the chupacabra is that it was created as a U.S. weapon experiment?). Most fascinating insight came when he picked apart the "case zero" eyewitness account that started the Chupa craze in Puerto Rico in 1995. Turns out, and Radford really puts in the research here, that the woman who first described the creature most likely based it on the alien in the movie "Species" which she had just seen. Seriously.
