The author does a good job of giving an overview of nerve agents, including technical challenges, practical limitations, and political issues. I recommend that listeners start with Appendix A first, then move into Chapter 1. I had a lot of technical questions while listening that were ultimately answered by that appendix.
I liked that the author addressed conspiratorial thinking around nerve agents head on, which gives a non-expert listener a solid feel for the information warfare occuring in conjunction with these matters.
The narrator was good overall, albeit a little slow and robotic at times. I listened at 1.3x and it held my attention. The narrator didn’t have any idiosyncrasies or mouth noises that sometimes can be distracting, which was nice.
