Query: Bundy's words are enlightening, the authors are not.

The main problem here is Keppel's massive ego and it appears not to have recovered from the beating it took from Bundy. To think someone who gives expert opinions in court can get so many things wrong, and potentially convict people based on nothing more than a hunch and his 'superior' deduction makes Keppel almost as scary as Bundy.From the first page 'Bundy probably couldn't reach orgasm unless the victim was dead or unconscious' Keppel's credibility falls flat on its face, since I don't think Bundy's wife was either when he impregnated her during a prison visit.In short, Keppel's not a smart guy and his conclusions are often tainted by his own emotional needs.Putting all that aside, Bundy's words are enlightening and make the book worthwhile.
