Whispering of Echoes - Chris Wendel - Bog

As a serial rapist who controls his victims using their social media presence strikes again, Det. Becker Gray must convince a victim who never reported the crime to come forward and help with the investigation. If she faces her past and agrees to help, the world she's built could crumble and her secret will be revealed. Never one to attack an investigation from only a single angle, Gray bends the rules to kick off a cold case investigation that ultimately leads to the department's past corruption.
