Meet the neighbour who waves politely, the friend who is the life and soul of a party, the colleague who buys the coffee. All are ready to kill, rape or harm. They live cheek by jowl with us; they look, sound and behave like us but they are evil and their crimes have shocked the world.

Evil Up Close hears from the people who knew, loved or trusted those hunted for vicious crimes, of those who lived alongside, laughed with or felt the warmth of a monster; the wives and daughters, husbands and sons, the friends, neighbours, detectives and prosecutors who have eye-balled evil in the dock.
