I really enjoyed this book. It reminded me a lot of books by Erik Larson, that flipped back and forth between two different stories that were linked due to location and circumstances. I remember watching an episode of The Crown on Netflix that focused on the smog, and I meant to look into that more and never did. I learned a lot about the cause behind that and the consequences. I didn't realize it was such a huge ordeal, so I certainly learned a lot about that. I had also never heard of this weirdo that was killing folks, and I do enjoy a true crime. I also especially liked that I got this during the two for one credit sale on Audible.
