In The Murder Stone, Louise Penny gives us a bit more of Armand Gamache the husband.
We also get a deeper look in the character of Peter Morrow and his life before Clara.
Most of the story is set in a fictional auberge in Bellechasse instead of Three Pines like the previous books.
The how of the murder is the most intriguing part this time.
There are plenty of suspects and motives.
