Trace Evidence in Tarrant County

Sheriff Carley Matheson had her hands full:
A sixteen-year-old unsolved murder and a strong
hunch that the killer had resurfaced and struck again.
As if things couldn't get any worse, the Texas Rangers
had sent Sloan McKinney—the one man she'd
always tried to keep at a distance—
to spearhead the investigation.

Now the only way to keep the citizens of Justice, Texas,
safe—and solve two connected crimes—was to join
forces. But someone resented Carley and Sloan digging
up the past, and before long two of Texas's finest found
themselves caught in the crosshairs of a murderer.
