The Unhinged
David Bernstein

Under the control of a madman... with no way out. Aaron Dupree has turned his life around. After serving six years in prison for his part in an armed robbery, he's released on parole. He's gotten a job and met a girl. Things are looking up... until he's pulled over for speeding-a parole violation-and blackmailed by the officer. He's forced to do terrible things to avoid going back to prison. Aaron soon learns how truly deranged and sick the officer is as he's dragged under a tide of ever-escalating horror.

He thinks he's seen the worst the cop has to offer until he meets the man with the scar, a vicious and twisted monster who lives only to deal pain.
