Fractured love, treachery and cold-blooded murder...
A nightmarish new case plunges Alex and Matthew into personal and professional chaos as they pursue a killer who traffics in the most vile of human traits. They quickly learn that the current killings are somehow tied to a decades old murder, which comes with a hefty mix of suspects. As they begin to dig into the cold case, they start to realize that one of their suspects is hiding an evil so horrific it can barely stand the light of day.
Unfortunately, the evil they stalk is only one side of a multi-sided problem. Twisted around old loves and never forgotten treacheries, the case threatens their growing feelings for each other and dangerously undermines their professional relationship, while pitting them against a killer more deadly than any they've faced. Can they survive the dual threat? Will they reach for each other when things get rough? Or will they let misunderstanding and menace kill the future they've started building together?
