The family's young live-in chef, Bill Kareama, was swiftly charged with murder and brought to justice. But the brutal crime scarred the idyllic town of Cambridge forever.

As Sloane lures a reluctant TK back into the fight, evidence emerges that casts new light on the Primroses - and who might have wanted them dead.

While the list of suspects grows, Bill's innocence is still far from assured. What will it cost Sloane and TK to uncover the truth?
