"Nightmare as a Child" is episode 29 of the American television anthology series "The Twilight Zone". It originally aired on April 29, 1960 on CBS. Plot. A school teacher named Helen Foley finds a strange and very serious young girl named Markie on the stairs outside her apartment. The girl seems to know her and tries to jog her memory about a man she saw earlier that day. The man arrives at Helen's door as Markie, frightened, runs out the back way. The man is Peter Selden, who explains that he worked for Helen's  mother when Helen was a child and was the first to find her murdered mother's body. Helen had witnessed the crime but blocked it out. When she mentions Markie, Selden tells her that her nickname was Markie as a child and shows her an old photo of herself. The girl in the photo is identical to the girl Helen met. When Selden leaves, Markie reappears. She tells Helen that she is Helen herself, and that she is there to force her to remember her mother's murder. With the child's prodding, Helen begins to recollect, then Selden returns  and confesses to the murder. He tells Helen that he had been about to do away with her that night as well, but could not because her screams had drawn people to the apartment. He has been "keeping tabs" on her because he knew one day she would recall the murder. Helen manages to run into the hallway and, after a struggle, pushes Selden down the stairs to his death. After talking to the police and returning to her apartment, Helen hears a young girl's voice singing the same tune as Markie. To her relief, the girl is just  an ordinary girl she does not recognize. She tells the girl she has a lovely smile ... and advises her never to lose it. Production notes.
