Yellow Fever and How to Cure It

The Doctor shows Peri an image of the Statue of Liberty on the TARDIS scanner. Venturing outside, they find out that they are not in the United States of America, but in a collection of miniature landmarks from around the world situated in Singapore. When walking around, they then noticed that statues begin to move and the Doctor realizes that they’re Autons. The travelers investigate and discover that the evil Rani has allied with the Nestene Consciousness when the Doctor previously encountered them before. She plans on creating new Autons with bullets that can bounce off corners and hands that can melt the nose and face of the adversary. However her villainous commitments are not the only thing that are confined, the Master is also in Singapore and is jealous of the Rani’s actions of working with the Nestene as he himself had previously done and wants to take down her plans. The Doctor and Peri for backup on UNIT with the somewhat retired Brigadier Lethbridge-Stewart, but the fighting task has just begun in a difficult manner.[2][1]

Producer John Nathan-Turner planned on having to film the story on location footage in Singapore while the BBC were featuring the series Tenko.[3] He and production manager Gary Downie went there in October 19, 1984, then when viewing the footage, whereas Holmes started to commission the writing of the first episode for Yellow Fever and how to cure it (also referred as Yellow Fever) on October 26.[3]

Shortly thereafter, Turner asked Holmes to feature the Autons, the Rani, and the Master to make the story interesting, despite the rights and rewrites of the story given, such as The Two Doctors.[3] All three episodes were commissioned on February 6, 1985,[3] and was intended as the third serial of Season 23,[3][4] and was to be directed by Graeme Harper.[3] However, on February 27, 1985, the BBC announced that the production of Doctor Who was to be suspended on a 18 month hiatus until Spring 1986.[3] The story then was rewritten without the Master, but ultimately abandoned due to budget-cost effectiveness and during the show’s suspension.[3] The story would plan to a semi-serial of the sub-season Trial of a Timelord, but the budget would also be too expensive to film at Singapore.[5]

Holmes started work on a story for concluding the season replacement, Trial of a Time Lord, called Time Inc on February 4, 1986, but was unable to create the story idea due to Holmes suffering Hepatitis B, and his story was abandoned when Holmes died of a short illness on May 24, 1986, whilst replaced by The Ultimate Foe by Pip and Jane Baker.[6]

Yellow Fever and How to Cure It remains abandoned without any book or audio adaptations. The story's information can be mostly seen in a documentary on the 2008 DVD of Terror of the Vervoids, Doctor Who: The Lost Season.[4]
