I just saw this very entertaining episode, which was the final one of the first season. Considering what happened involving Rod Serling at the end, I wonder if they knew weather or not they had been renewed for a second season at the time it was filmed. If the show hadn't come back for another season, it would've been a clever finale.
shareI had to look it up. But I remember it now. Clever story.
Coming home, Victoria West spots her husband, playwright Gregory West, through the window sharing a drink, and flirting in his study with Mary, an attractive young woman. Gregory quickly destroys a tape, which displeases Mary. When Victoria barges into the room, Mary is nowhere to be found.share
Gregory explains to his wife that any character that he describes into his dictation machine will appear according to his description. To make the character disappear, all he has to do is cut out that portion of the tape and throw it into his fireplace.
Believing none of this, Victoria tells Gregory that he is insane and she is going to have him committed. In response, Gregory pulls a section of tape from his safe and explains that it contains her description, revealing her to be one of his creations, but that recently she has begun to exert her own independence from him. Refusing to believe him, Victoria snatches the tape away from him and throws it into the fire, and promptly begins to feel faint. She realizes too late he was telling the truth, and disappears as the flames consume the tape. Frantic, Gregory rushes to his dictation machine and begins to re-describe Victoria. He quickly reconsiders and instead describes Mrs. Mary West as his wife. Mary appears and fixes her husband a drink, apparently lacking any memory of her previous interval of existence.

Interesting premise.
