The Knock Knock Killer

By Nicholas Sawyer

Three different women are found murdered inside their homes in Alexandria, Virginia. The local authorities suspect a serial killer is at work. After tirelessly working the case, the police call in extra support. Just before a fourth victim is found, the FBI's Behavioral Analysis Unit is called in to help with the investigation. Special Agent in Charge Jack Burns, the unit chief of the team, works alongside Detectives Wrestler and Greyson to build a solid profile and catch the killer before another body turns up.
