Newly divorced school teacher Mia Anderson is looking forward to exploring her identity without her exhusband's criticism. But a frantic call from her much wilder twin Margo suddenly plunges Mia into her sister's life, which Margot has fled - leaving a dead man in her wake. Before Mia can unravel Margot's disappearance, she's faced with Matthew Gray, the dead man's distraught brother. Asking him for help is a long shot - but It's the only way to carry out a dangerous charade. Decelt is the last thing Matthew wants in his life - it ruined his parents' marriage, and it killed his cheating brother, who was seen flirting with Margot the night he was murdered. But Mia is sure that her sister is only a pawn in this deadly game, and he can't let her investigate on her own - not when she's determined to put her own life on the line.
