YES! This is the book we've been waiting for.  Emotion, stunning, hilarious and also tearful, the best characters and the best village and the best writing. I devoured this book and can only hope we will get more (especially after that ending because I cannot wait to see how Flavia goes from there). I loved seeing more of Undine (even thou she irked Flavia) because she provided much-needed comic relief.  This book was equal parts so very cozy and so very heart-pounding.  Flavia is my all-time favorite fictional character and sleuth and so this book was so fun. I was fascinated by the chemical processes and how they were vital to the investigation (also the reference to the mass spec - a flashback to my college days). I love how she works with Dogger and how he treats her as an equal. I don't want to even give one thing away, so suffice it to say that this book is perfection especially if you are a fan of the series.

Note: I listened to the audiobook and I HIGHLY recommend that format for this whole series; the narration is perfection.

Thanks to the publisher for a free ebook copy and free audiobook copy; my review and thoughts are my own.
