For more than two decades, investigators hunted one of America's most elusive serial killers, and this book follows one man's effort to understand him. On July 15, 1982, the strangled body of a young woman was found snagged on the pilings of the Green River in Washington State. Soon the so-called Green River Killer was linked to at least forty-nine more deaths, and the case showed no sign of closing.

The authorities then received a startling letter from Ted Bundy, the notorious serial killer who was on death row in Florida. Bundy offered to help catch the Green River Killer, but on one condition: he would speak only with Robert Keppel, the former homicide detective who had worked to trace Bundy's cross-country murder spree.

The book reveals those conversations, in which Bundy considers the Green River Killer's motives and methods and also discloses dark secrets of his own.
