Good Behavior: Good, Not Best
Good Behavior is simultaneously the definitive collection of Letty Dobesh stories by Blake Crouch and no longer the definitive story of Letty herself.
These stories were originally published as three separate novellas over the course of a few years. As of 2016, they are also the basis for a TNT series starring Michelle Dockery in her first post-Downton role in an ongoing series. The stories are collected in one volume along with author commentary.
However, unlike other book adaptations, I think I might recommend watching the show *before* reading Good Behavior. These stories read a hell of a lot like the rough draft of the show, and might best be appreciated with that in mind.
