This is an enjoyable mystery. The characters are interesting, not only do they solve crimes, but they have difficult interactions with each other, some of which get resolved in the book. The English villages are a delightful setting at least when no one is being poisoned.
The plot is good up to a point. I thought the early part of the book was very clever, but after the murder was apprehended, the story continued with characters who were only tangentially connected to the action. Finally, there was a third part to the story where difficulties among Agatha and her staff were resolved. If you're a long time reader of this series, the epilogue may be interesting, but this is my first book, and I felt the last two sections were padding the page count.
If you like cozy mysteries with a fast pace and an interesting setting, you may enjoy this book and the series, but if you're a serious mystery reader you may want something with more meat. This is a very light story. Too many times things are solved by serendipity.
I reviewed this book for Net Galley.
