Not only was this a dive into the psychology and motivation of the Green River Killer, but we also get another look into the grisly career of Ted Bundy, written by the guy who caught him -- Robert Keppel.

A bit on the repetitive side, as Ted's favorite topic was Ted, Keppel relives his career on the hunt for one of the most infamous serial killers in the US and how he elicited shocking confessions from Bundy on Death Row in addition to consulting on cases like the Green River Killer, the Atlanta Child Killer and more notable cases.

One of the most poignant aspects was Ted thinking he was relevant, that he could help catch the Riverman. While there were suspects in mind already, Ted didn't need to know, Keppel was able to gain important insight into those who are like Ted -- cold, calculating killers who will do anything to keep killing and not get caught.
