Bad Humans - Keep In The Light, #3

Abused by his alcoholic father, Rodney has always had a crush on Liz: the only person who was kind to him. Armed with a magic artifact, Rodney and Liz can see the evil in people. They encounter two such individuals: an ambulance driver who causes accidents so she can rush to the scene and save the lives she just took, and a nursing home orderly who enjoys taking advantage of the helpless. These natural evils intersect with the supernatural evil they've encountered earlier, as well as the mysterious Man in White, who is on his own mission against shadows and demons.
Can Liz and Rodney stop the evil that is in one man's soul, and will the Man in White be on time to save them from an even greater evil?
