I have to say, that i think the other two reviews are a little harsh on Agatha Raisin number 09.
If you look through the Amazon listings of the Agatha Raisin series you will see that any of the books that are set away from Carsley (and that don't feature James highly) get worse reviews than the ones that do, this is only natural i suppose as we miss the regular character like Mrs. Bloxby, James Lacey, Bill Wong, etc. But we shouldn't condemn the book just because of that, after all there are only so many murders that can happen in Carsley.
I think what maybe the other reviewers felt wrong about this book is that really the murder plays second fiddle plot wise, and that the main focus of the book is about Agatha. She isn't really all that interested in the crime, or goes at it like her normal bulldog self; she tends to spend more time with the residents of the Garden hotel or new love interest Jimmy Jessop. She learns some tough and lessons, as well as softening up and trying to help people more. In General the book shows her grow, something she must do before James comes back on the scene.
I really enjoyed learning about Agatha in this book, and enjoyed the characters (particularly the demanding friendship between Mary and Jennifer which I thought was well developed) and setting of a small sea side town out of season, and that the witch craft element of the story was kept minimal.
Deff deserves more praise !
