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.
