ONE LAST KILL: A dark, gritty detective mystery, a gripping serial killer crime thriller with a twist. (The Far South Series Book 1)

Bobby Ress is a cop with a simple life.
He believes in making a difference.
He loves his wife and his daughter. He has a place in the world.
Then people start dying, a lot of them, in horrible ways. It's a case like no other. And step by gruesome step the simple, true things Bobby knew to be right and good begin to make less and less sense. Because Bobby is learning about pain. He doesn't like to admit it. He doesn't like to know, but he's slowly realizing: If you hurt someone bad enough for long enough then there's nothing, absolutely nothing, they won't do.
