Book 2 of R.B. Schow’s Sadie Gray series is The Sight Unseen.
When the San Francisco Field Office quietly passes on a high-profile disappearance, Sadie and her partner, Brad Tulle, are sent in to clean up what others won’t touch. Leona Kolsch, a Bay Area socialite with enemies she never saw coming, has vanished without a trace. The last confirmed sighting wasn’t in California. It was 700 miles away in Utah.
What starts as a missing person case quickly unravels into something much darker.
As Sadie and Brad follow the trail across state lines, the case begins to multiply—one victim becomes two, then three—and a chilling pattern starts to take shape. This isn’t random. This is calculated. Controlled. Personal.
They’re not just chasing a suspect.
They’re hunting a serial killer who targets women with eerie precision, slipping in and out unnoticed, always one step ahead. And the deeper Sadie digs, the more unsettling the truth becomes: this killer isn’t just after victims.
He’s after something they represent.
With time running out and the pressure building, Sadie and Brad have to connect the dots before Leona disappears into a growing list of cold cases—all marked by the same haunting signature.
But how do you catch someone who plans everything… and leaves almost nothing behind?
This one pulled me in fast. I loved how the story expanded beyond a single case—it made everything feel bigger, more urgent, and honestly a little more chilling. Sadie continues to be such a strong, steady lead, and I really enjoyed the dynamic between her and Brad as the stakes kept rising.
The pacing felt tight, with just enough twists to keep me guessing without getting lost. And the underlying theme—the idea of a killer driven by something deeper than opportunity—added a layer that stuck with me even after I finished.
If you like crime thrillers that build slowly but hit hard, this is definitely one to add to your list.
