Traces the serial murders of the notorious Green River Killer, profiling Gary Ridgway as a happily married man who worked for the same company for thirty years, the case's approximate 40,000 suspects, the killer's disturbing capacity for luring and hiding his victims, and the DNA breakthroughs that established his link to the killings.

Rule writes the account of a modern monster, a killer who walked among us undetected. It is also the story of his quarry -- of who these young girls were, and who they might have become. A chilling look at the darkest side of human nature, this is the most important and most personal book of Ann Rule's long career.
