A Trick of the Light by Louise Penny (2011)

Clara Morrow - one of the first characters I remember meeting in the first book of the Armand Gamache series - is finally having a major exhibit of her work in Montreal, but the joy of it is dampened by the discovery of a childhood friend murdered in Clara's garden during the party after the opening. Clara feels that the former friend has again taken the spotlight away from her. Her husband Peter is feeling great pangs of envy. There are art dealers waiting around like vultures to sign Clara as their artist. Complex sets of emotions that Gamache has to wade through to get to the truth in the deceptively quiet setting of Three Pines. Read a few months ago, so details have already faded, but glad that there are plenty more books in this series to enjoy.
