July 15, 1982: a woman's strangled body was found, caught on the pilings of Washington state's Green River. Before long, the "Green River Killer" would be suspected in at least forty-nine more homicides, with no end in sight. Then the authorities received an unbelievable letter from the infamous serial killer Ted Bundy -- then on Florida's death row -- offering to help catch the Green River Killer. But he would only talk to one man: Robert Keppel, the former homicide detective who had helped track Bundy's cross-county killing spree. Now these conversations are revealed, in which Bundy speculates about the motive and methods of the Green River Killer -- and reveals his own twisted secrets as well. Now, as never before, we look into the face of evil...and into the heart of a killer.
