An ad appears in a London paper, looking for a woman with a sense of adventure and no ties. A young woman lands the job, says goodbye to her two roommates, and never contacts them again. Six weeks later, one of the other roommates finds the same ad in the paper and applies. She is hired immediately, and despite her close friendship with her roommate, never writes or calls. Four months later, the last roommate sees the ad in the paper again, and determines to get to the bottom of the mystery.

There's an in-joke in this episode - when the policeman is questioning the heroine about finding the impostor Babs Bryant at the American Embassy, he mentions about the name being quite common in York - he then makes an indirect reference to The Avengers - he says something along the lines of "a TV series comes on and suddenly, everybody gets called Emma" - a reference to Emma Peel from The Avengers. Both Thriller and The Avengers were created by Brian Clemens. See more
