Death in Darkness — Nell Goddin

A disturbed wife. A nanny. And a pack of cowardly, lying friends... Simon Valette, a cultured and successful Parisian, moves his family to Castillac looking for peace and quiet. But before they've had a chance to settle in, someone is found murdered in the library. Molly and Ben work double-time to disentangle all the lies--including those told by their own friends. Will they manage to trap the killer before another victim trusts the wrong person and winds up dead?
