Rosalie Hart's world has been upended. After her husband confesses to an affair, she exiles herself to her late aunt's farmhouse on Maryland's Eastern Shore. With its fields untended and the house itself in disrepair, Barclay Meadow couldn't be more different than the tidy D.C. suburb she used to call home. Just when Rosalie feels convinced things couldn't get any worse, she finds a body floating in her marsh grasses.
