1789

In 1789, during the French Revolution, a young French aristocrat named Jason was sentenced to death by guillotine, but was rescued by the Sixth Doctor and became his companion. Later, the meddling of a Dalek caused the TARDIS to return to revolutionary France. Jason was arrested once more and his sentence was almost carried out but he managed to escape again. (AUDIO: The Ultimate Adventure)

1789 was also the year that Rebecca Macardle stopped being a prostitute, and instead took up employment as a government agent. (PROSE: The Adventuress of Henrietta Street)

Behind the scenes
