One of Us Is Dead

I got through this on audio as I worked on a tough project and the characters and setting hooked me right away. It starts by establishing some nauseating social dynamics and bad-guys. The story and writing style is engaging, and the characters were interesting but the villain was over-the-top and overwritten. This wasn't enough to take me out of the story but I am not sure if this is because i was listening to the story vs reading it. I am not sure I would have been invested enough to read this in a traditional book. The ending a bit flat and not very satisfying.
