This book should be called ' Why talk to serial killers when you know everything already?' as Mr. Barry-Dee seems to think that we are far more interested in what he has to say anyway. Though he has, apparently, had a great deal of interaction with the people he discusses you would be forgiven for doubting that as he only ever includes a few words from them at the end. It is overly sensational, describing one man as 'a monster in every sense of the word'. I don't see how this can be the case, as one sense of the word is 'a mythological creature' which seems ludicrous unless we all had a mass hallucintion that this man exists. As someone who is studying to (hopefully) become a forensic psychologist, I find books like this one abhorrent as they merely serve to enhance the idea that these people are a different breed to the rest of us, which I find rediculous and not very helpful to those who wish to understand these people better. In addition to this, having read about some of the cases before, I find some of his inferences laughable. This is a man who clearly has his own agenda (pro death penalty, in my opinion). The fact that he takes pains to prove that Henry Lee Lucas is a 'liar' because he contradicts himself seems to suggest that he has little real appreciation of insanity as he judges him on far too rational terms. If you want to learn about this subject, I would suggest 'Guilty by Reason of Insanity by D. Otnow or any of the wonderfully sensative and unsensational accounts of crime wriiten by Brian Masters. Read this is you want to get all the gory details with no genuine thought attatched.
