Do Not Forsake Me Oh My Darling is the thirteenth episode of the television series The Prisoner, produced while Patrick McGoohan was in America filming Ice Station Zebra. As a workaround to McGoohan's absence the writers contrived to have Number Six's mind implanted in the body of another man (Nigel Stock), who is then sent out of the Village to help capture a scientist. As a result, McGoohan appears in the episode for only a couple of minutes.
But in this earlier draft of the story, Number Six's memories of the Village are unquestionably erased. Six awakens in his flat in a furious mood, storming to his office to angrily resign. Only at the office does he realize that his appearance is not his own and that a year of his life is missing.
Fearing that this is a ploy to force him to reveal confidential information, Six leaves the office, determined to find Saltzman (who became Seltzman in the aired version), the inventor of the body-swap machine. Meanwhile, Number Six's former employer, Sir Charles Portland, is shown to be in collusion with a mysterious, unseen figure, an apparent agent of the Village. They are collaborating to manipulate Six into locating Saltzman, intending to follow Six as he finds the scientist.
Six returns to his house to find Janet, his fiancee, who doesn't recognize him. Six offers Janet a deal in exchange for locating her missing lover. He later meets her at her birthday party and reclaims from her a receipt for developed photographs held at a camera shop, which Six gave to Janet a year ago. He proceeds to kiss her intimately, in a manner that reminds her of her disappeared lover, and then departs from the party.
Six procures the photographs from the shop, which, overlaid atop each other, produce a map with a set of co-ordinates in Kanderfield, Austria. Six finds Saltzman there, and convinces Saltzman of his identity by referring to their arranged meeting at which Six never arrived. However, Saltzman notices that someone has followed Number Six. It is Potter, a former colleague of Number Six's, sent by their employers to tail Six. And tailing Potter has been an agent of the Village, who gases Saltzman, Six and Potter unconscious and proceeds to transport the scientist and Number Six back to the Village.
Saltzman is forced to show his captors how to reverse the mind-transfer process, in order to Number Six and Colonel Oscar to their proper bodies. The Village lacked the ability to perform the reversal; that is why they wanted Saltzman. Saltzman says the reversal requires a third party as a "medium" for the transfer. Saltzman volunteers himself. Number Two consents, and Six, Oscar and Saltzman are linked to the mind-transfer machine after Saltzman reconfigures it.
The unconscious body of Number Six awakens with the correct mind in place. However, the process has been too much for the elderly Saltzman, who is dying. Colonel Oscar is flown out of the Village in the helicopter while Number Six sits by the dying Saltzman's side. Later, Number Two basks in his victory while Six awaits Saltzman's end. But then Six reveals that the reversal process never required a third man -- that was a lie.
Saltzman then revives briefly, speaking of the orders of Number One, and then dies. Six grimly bids farewell to Saltzman -- who is actually the Colonel, in Saltzman's body. A horrified Number Two calls the control room, only to learn that the helicopter and Saltzman are out of range.
This original version of the story is more deeply developed in almost all respects. Number Two is portrayed as an arrogant, self-satisfied braggart who boasts to the Butler of being the one Number Two who won't be leaving his position. While the televised version ignores the issue of Number Six's resignation, the original script has Six angrily carrying it out. His interactions with Janet are also slightly different, with Janet being forceful and unwilling to play what she thinks is a game with an employee of her father's.
Absent from the televised version but present here is the treachery of Number Six's superior, Sir Charles Portland, speaking to an unidentified 'Voice' who is never seen and is observing the transplanted Number Six's actions. Finally, the script makes inventive use of McGoohan's short time. One scene has Number Two conversing with the Colonel-in-Six's-body, who is represented through what the script describes as a single shot of McGoohan. Later, the script has Number Two watching "appropriate stockshots" of Number Six, whose body the Colonel occupies, with Number Two commenting that the Colonel lacks Six's charm. And when Six awakens restored to his own body, he declares, "I'll tell you nothing! I'm a free man!"
At the end, Six sits with the dying Saltzman before revealing that the reversal process didn't need three men. "Only one could end up free," says Number Six in this brief scene. "It could have been me. But I felt it should be Saltzman. Because I'm going to escape anyway."
This script was apparently rewritten in the absence of Patrick McGoohan and after the departure of George Markstein, becoming what was seen onscreen.
