Sara Kingdom
Sara Kingdom is a fictional character played by Jean Marsh in the long-running British science fiction television series Doctor Who. A security officer for Mavic Chen from the 40th century, she would later join the First Doctor and Steven to work against Chen's interests. She is sometimes classed as a companion of the First Doctor but the BBC's official Doctor Who website does not include her in their list of companions. Her status as a companion is commented upon in its Episode Guide.
She appeared in parts four to twelve of the twelve-part 1965 serial The Daleks' Master Plan. Only two episodes still exist in the BBC archives in which she appears. Her character took on elements of the companion role to replace the character of Katarina who was killed off earlier in the same story.

Sara is a Space Security Agent, the sister of Bret Vyon, another agent who is aiding the Doctor in trying to defeat the Daleks. Told that Vyon is a traitor by Mavic Chen, the Guardian of the Solar System (who was in league with the Daleks) and ordered to kill whoever is working with him, she shoots her brother and is about to do the same to the Doctor and Steven when they are transported across space to the planet Mira. There she learns, to her horror and grief, that her unquestioning obedience has not only led her to unjustly kill her brother, but also that by doing so she has prevented Vyon from warning Earth of the Dalek plot. She then joins the Doctor in his fight, briefly travelling in the TARDIS to several different locations in space and time as the Doctor and Steven try to return the ship to Kembel for a final confrontation with Mavic Chen and the Daleks.
