Regarded by many as the best-ever episode of The Prisoner, "Do Not Forsake Me Oh My Darling" was written by Vincent Tilsley. Number Six awakens with the belief that he is actually another man -- to be exact, an Army colonel (Nigel Stock). Failing to recognize his own face in his own mirror, the confused protagonist also learns that "The Colonel" has been missing for a full year. The answer to the mystery rests in the hands of one Professor Seltzman (Hugh Schuster), the inventor of an insidious intellect-transfer machine. Clues essential to the action include a reference to Number Six's former fiancée, and an inventory of the former intelligence agent's code names. Also appearing are Zena Walker as Janet and Clifford Evans as the new Number Two. As originally conceived, "Do Not Forsake Me Oh My Darling" was supposed to have been the series' ninth episode, but instead was rescheduled as episode 13 on British television, making its first appearance on January 7, 1968. When The Prisoner was rebroadcast in America on CBS, the intended episode chronology was restored, and "Do Not Forsake Me Oh My Darling" was properly shown right after episode number eight ("Dance of the Dead") on August 3, 1968.
