So, I'm very picky when it comes to non-fiction, and I wasn't quite sure what to expect here. I am absolutely delighted to say that this went above and beyond my expectations.

I thought the writing was engaging. It had a decent pacing and was easy to follow. I loved reading about Agatha Christie's history in pharmacology. It was absolutely fascinating to hear about her experience with her training/journey to become a certified pharmacist and how that played into her storytelling.

The author also does a really good job of introducing the poison and/or poisoning method and pairing it with a book title that went along with it. It did have sections that were a bit more in-depth with the science of it all, but again, everything was easy enough to follow. (Thank you, Harkup, for taking pity on all of us who only have a layman's knowledge of chemistry!)

I really enjoyed this comprehensive breakdown of plotting with poisons and other deadly things, and I think if you're a Christie fan, you will too.
