I thought this book was really interesting and it's one of the first books I've actually taken notes on so I can better remember what I listened to. I thought each of the poisons covered was well explained and researched, and I particularly enjoyed the chemical and biological descriptions of what each poison does to the human body. I also liked the political aspects of some of the chapters, as well as the details of how each poison had been used throughout history.

Admittedly, I wasn't as big on the true crime stories that were told. While I thought they were generally interesting, they seemed to be a little more anecdotal (or more fictitiously fleshed-out) than I would have liked, and it was definitely the element of each section I was least interested in. Maybe for that reason I would try more of a medical/historical book and not one that focused on true crime so much in the future, but I still really enjoyed my listen.
