A Rule Against Murder by Louise Penny.
This is the 4th book in the Armand Gamache series. It was also published under the name "The Murder Stone".
As with her other books, I loved it! This book took place mainly at a vacation spot so it didn't have as much about all of the residents of Three Pines but I still enjoyed it.
I also found out that I can order a tea cup with the Three Pines logo on it. The cup is pricey when you add the shipping from Canada but it sure is tempting!
'til next time...
