Wait Until Dark is a play by Frederick Knott.

The mystery thriller's heroine is Susy Hendrix, a blind Greenwich Village housewife who becomes the target of three thugs searching for the heroin hidden in a doll her husband transported from Canada as a favor to a woman who since has been murdered. The trio tries to convince Susy her spouse has been implicated in the crime and the only way to protect him is to surrender the doll. More murder and mayhem ensue when she refuses, with the stage lights turned off for the final scene when Suzy levels the playing field by plunging her apartment into total darkness.

zy Hendrix: I won't give it to you. at: "I won't give it to you"? "I won't give it to you." You remind me of somebody else who said that! Only she said..."I don't know where it is! I don't know! I don't KNOW I DON'T KNOW I DON'T KNOW I DON'T KNOW I DON'T KNOW!"

at: Oh, Suzy! You don't have to be ashamed. Everybody's frightened of something, I... ooooooo! I have gasoline here! Gasoline. Hmm? Gasoline. This place will go up like a matchbox! The big question, Suzy, is do you want to be outside in the street? Or locked in there with Mike? It's up to you. So, will you give it to me now? zy Hendrix: No. at: 'I won't give it to you'. 'I don't know!'. 'I don't know, I don't know, I don't know I don't know I don't know'. THEN, as it always happens, finally something seemed to snap. Ohhh, yes. And she told me everything she knew. As it turns out, she didn't know where it was, but... she told me everything she could! At last, she wanted to tell me, but, like her, you won't stop at that, will you, Suzy? Hmmm? No! After I'd finished 'questioning' her, she went on, and she told me other things. Little, useful things that just might come in handy, hmm? And then she told me OTHER things. Things I didn't even want to know. Little, intimate things about herself, and Mike, and Carlino... and I said 'Now that's enough, Suzy. That's enough I don't want to know any more' but she went ON AND ON AND ON AND ON... and then finally, she was dead. Now, I'm not going to ask you for it again, Suzy, so when you want to give it to me, you have to tell me. Will you go in there, hmm? Shall I HELP you, Suzy... [Suzy hurls a bowl of hypo into Roat's face]

at: Of course, I knew they'd try and kill me once we had the doll. But, when Carlino walked up to his car just now outside in the street? And saw it start up all by itself and drive straight at him, hmmm? I just couldn't resist turning on the lights to catch his expression, I... I don't think I've ever seen anybody look quite so surprised.

at: Now... what was it you wanted to say to me? zy Hendrix: I'll give you the doll. If you'll just go and leave us alone. at: You have to say 'Please may I give you the doll'. zy Hendrix: PLEASE may I give you the doll? at: You may!

zy Hendrix: [Suzy is trying to make her apartment completely dark] Can you see me moving? oria: Yes, just. zy Hendrix: There must be a light coming from somewhere, where is it coming from? oria: From under the door at the top of the stairs. zy Hendrix: Hell! OK, wait, There's a broom in the spare closet. Go out in the hall and smash every light you can see, just go until you can't see anything. oria: WILL DO, ha ha... [she does] All out! zy Hendrix: Close the door. Now, can you see anything? oria: Nothing at all. zy Hendrix: All dark? oria: Yes. zy Hendrix: Good! OK, off you go then, know what to do? oria: Asbury Park, and tell Sam everything! zy Hendrix: Lock this door, check that the street door is locked, then go out the back way and run until you find a taxi! oria: Bye, Suzy... zy Hendrix: Gloria? I don't know anyone who could do this as well as you. oria: Oh boy, I wish a thing like this would happen every day, HA HA!

at: Well, Suzy... now all the children have gone to bed. Now we can talk.

Susie's husband is asked to hold a doll for a woman as they get off an airplane. She disappears. Mike and Carlino are small time hoods who find the woman's body in Susie's apartment, placed there by her partner, Harry Rote. Susie's blindness is the key to them searching the apartment for the doll that contains smuggled drugs. Mike pretends to be an old friend of Susie's husband while her husband is away and together the crooks invent a story of a police investigation of her husband that only the discovery of the now missing doll can save him from. Rote is a killer, and his stalking of Susie becomes more and more obvious as the story unfolds, leaving us with the question, how does a blind woman defend herself? Written by John Vogel

After an airplane trip, a young woman asks Susie's husband, Sam, to keep a doll for her to avoid spoiling the surprise of her daughter's gift. But the real reason is to avoid her partner, Harry Roat, whom she hopes to cheat of the drugs hidden in the doll. Harry discovers her treachery, murders her and leaves the body in Susie's apartment, where he has tracked Sam and the doll. He concocts an elaborate plan, involving Mike and Carlino, small-time hoods, to get Susie, who recently lost her sight in a fire, to reveal the doll's hiding place. They lure Sam away and take advantage of Susie's blindness, posing as an old friend, a police detective, and a father-son pair of eccentrics. Susie eventually catches on and, with the help of her young neighbor, Gloria, shows everyone that she is indeed "a world-class blind lady." Written by Joe Jurca
