Wait Until Dark, written by Frederick Knott, is a masterfully constructed thriller that moves from one moment of suspense to another as it builds toward an electrifying, breath-stopping final scene. A sinister con man and two ex-convicts are about to meet their match. They have traced the location of a mysterious doll, which they are much interested in, to the Greenwich Village apartment of Sam Hendrix and his blind wife, Susy. Susy knows the only way to play fair is by her rules, so when darkness falls she turns off all the lights leaving both of them to maneuver in the dark until the game ends. Keith A. Anderson directs.
