Wait Until Dark is a gripping stage play written by Frederick Knott, first performed on Broadway in 1966.

The play centers around a blind woman named Susy, who unwittingly becomes the target of a group of criminals searching for a valuable doll hidden in her apartment.

As the criminals become increasingly desperate and violent in their attempts to retrieve the doll, Susy must use her wits and resourcefulness to protect herself and outsmart her attackers.

The tension in the play builds steadily as the audience is kept on edge, wondering if Susy will be able to survive and outwit the criminals.
