Now, six years later, the discovery of Holly’s remains seems to be the definitive proof needed to close the case. As Cat and Parnell look closer, they find discrepancies that raise troubling questions. But someone will do anything to keep past secrets hidden --- and as they inch closer to the truth, they may be putting themselves in jeopardy.
