A missing couple. A marriage built on secrets. And a case that will force Sloane Merritt to question everything she believes about love, loyalty… and what people are capable of hiding.
When Brantley Williams hires Atlanta private investigator Sloane Merritt to find his brother and sister-in-law, the situation doesn’t make sense. Callum and Meredith Williams vanished without a trace—no signs of struggle, no warning, no explanation.
At first glance, it looks like they left willingly.
But the deeper Sloane digs, the more disturbing the truth becomes.
The timeline doesn’t hold.
Their behavior in the weeks leading up to their disappearance was out of character.
And the life they built together begins to fracture under scrutiny.
Did they run? Were they taken? Or is one of them responsible for the other’s disappearance?
All marriages have secrets.
The small ones get overlooked.
The dangerous ones have a way of surfacing.
Meanwhile, a long-buried lead finally emerges.
David Harding has been found—and the truth behind the DNA match is finally within reach.
For the first time in twenty years, Sloane isn’t just chasing a ghost. She’s closing in on the truth about Eden Pike.
But the truth was never lost. It was hidden—on purpose.
Perfect for fans of missing persons thrillers, female-led detective series, and gripping psychological suspense, Dual Motive takes the investigation deeper than ever—where every relationship hides a secret… and the truth about Eden Pike is closer than it’s ever been.
