Murder at the Mendel — Gail Bowen

As a child Joanne was friends with Sally Love and her parents, but the friendship languished after Sally's father died and she moved away, eventually becoming a very controversial artist. When the Mendel Gallery opens an exhibition of Sally's work, Joanne is eager to attend and to renew their friendship. But it's not so easy being Sally's friend anymore, and soon Joanne finds herself ensnared in a web of intrigue and violence. When the director of a local private gallery is brutally murdered, Joanne finds that the past she and Sally share was far more complicated, and far more sordid, than she had realized.
