Yellow Fever and How to Cure It (unproduced TV story)

✅ Yellow Fever and How to Cure It is an unproduced story for Doctor Who. It was to be the third appearance of the Autons as part of the aborted 1985 season of Colin Baker's Doctor.

It was meant to be scripted by Robert Holmes, and the story was to run for three forty-five minute episodes.

Plot outline
It was to take place in Singapore and feature the return of the Autons, with suggested appearances by the Master, the Rani and the Brigadier on holiday. This story was written later than the rest for this season, so its script was only in its proposal form at the time of its cancellation.

Legacy

 * This is the first of only two original season 23 scripts which did not receive any kind of an adaptation. There were three main reasons: First, the original author for this story, Robert Holmes, died in 1986 and so was unavailable when Target Books elected to publish novelisations of the first three season 23 stories in 1989 and again when Telos Publishing attempted to publish the scripts in 1990. The script was also in its early infancy when abandoned, with only a single episode and a synopsis written before the Trial of a Time Lord story arc replaced the lost season.
 * The Autons finally returned to the screen in the television story Rose.
 * The Brigadier never encountered the Sixth Doctor on screen, with the exception of the NOTVALID Dimensions in Time, his next meeting being with the Doctor's seventh incarnation in Battlefield.
 * The Sixth Doctor and Lethbridge-Stewart met in the audio story The Spectre of Lanyon Moor.
