If you're looking for actual interview transcripts with serial killers, forget it. While the author claims to have logged "counltess" hours in correspondence and meetings with various murderers, he has very little to show for the work that he supposedly did. Many of the quotes in this book come from sources such as statements to police or court transcripts that are publicly available. The names and crimes of the killers are already well documented elsewhere. Worse still, the style suffers from embarrassing cliches, pretentious hyperbole, and bogus moral outrage that is expressed while missing no opportunity to titillate the reader.This is a lame piece of hack work.
