Hollow Point - The Silencer Series, #7

Somebody is shooting police officers. After several killings, and no progress on finding the shooter by the police department, Recker is asked to lend a hand. One of Vincent's men inside the department, a homicide detective, reaches out to The Silencer, setting up a meeting through Vincent. As Recker, Haley, and Jones investigate the killings, they start to find more questions than answers, and realize that everything is not as cut and dried as it seems.
Once the supposed killer is finally found, Recker thinks he may have been played. He's not so sure that it wasn't a plant and the man was framed. All of which leads him to question, if it's someone else behind the shootings, who has the power and motivation to pull it off? And why?
