For twenty-one years, Gary Ridgway carried out his self-described 'career' as a killing machine, ridding the world of women he considered evil. The world's most prolific serial killer's eerie ability to lure his victims to their deaths and hide their bodies made him far more dangerous than any infamous multiple murderer in the annals of crime.

Happily married, Ridgway worked for the same company for thirty years, eventually emerging as the prime suspect among 40,000 scrutinized by the Green River Task Force. Still, there was no physical evidence linking him to the murders, until 2001 when King County Sheriff Dave Reichert utilized a new DNA process on a saliva sample he had saved since 1987 with stunning results. Ann Rule has followed the case since the first body was found in July 1982. She has compiled voluminous files and gained unparalleled access to all the key players - from Reichert, who has stated that 'there's only one writer who can do this story justice - and that's Ann Rule', to those close to Ridgway and his victims.

GREEN RIVER, RUNNING RED is a harrowing look at a modern monster - a killer who walked among us, undetected. It is also the story of his quarry, who they were - and who they might have become. Two decades in the making, this is the most important and most personal book of Ann Rule's long career.
