I listened to this story in the middle of a backpacking trip during a rainstorm in a tent, so I was pretty much immersed before it started. Maybe that amplified the appeal this story had for me, because I enjoyed it. I don't tend to try to categorize stories that much, so that wasn't a hangup for me. More than the setting though, there are also specific interactions in the story that I thought were really well done that pulled me in. Mainly the tension between Cohen and Garrett, which not only was interesting, but I also liked the outcome. I also liked how my perception of Bitner evolved through the story. I started out not liking him much, but as more events unfold, a noble character is revealed. He was a well portrayed guy who's harsh in words but his actions are what he holds important and reveal his nature. The overall story of "Catch the Killer" is one we've heard many times, but I think the people in this one make it special.
