Evil Lives Here Season 4

What if the person closest to you were a devil in disguise? Would you see the signs? EVIL LIVES HERE tells the true, heart-stopping stories of people who shared a home with a killer. In each case, they see suspicious signs that something is amiss...something they can't quite put their finger on. Sometimes, they turn a blind eye to those signs, not wanting to know where it came from. Eventually, they must come face to face with the horrible truth: that the person they loved, the person they trusted, is a monster.
