Katarina is a fictional character played by Adrienne Hill in the long-running British science fiction television series Doctor Who. She is a companion of the First Doctor. Katarina appeared in the programme from November to December 1965, in five episodes over two stories. For 35 years, none of the episodes to feature her existed in the BBC archives until January 2004 when the second episode of the 12-part serial The Daleks' Master Plan was found. An inhabitant of ancient Troy, Katarina was very unused to modern concepts: she didn't even know what a key was. Katarina was conceived as a permanent companion but this was quickly re-evaluated by the writers, including producer John Wiles, as they realised the writing challenges that came with such an unworldly character. Unable to remove the character from upcoming scripts at short notice, they decided to write out Katarina by killing her early in The Daleks' Master Plan, her second story, making her the first companion in the series to die. Katarina's death was the first scene Hill filmed for the series. Her role as companion in The Daleks' Master Plan was given to the character of Sara Kingdom, who was also killed off in the same story. Character history Katarina is introduced in the serial The Myth Makers, which takes place during the siege of Troy around 1200 BC. She is a handmaiden of the prophetess Cassandra, who was also the princess of Troy. Before meeting the Doctor she was little more than a slave. During the Myth Makers, she was sent by Cassandra to spy on the First Doctor and his friends, particularly Vicki, known to her as Cressida. Katarina befriends Vicki, who sent her to help the Doctor get Steven back into the TARDIS after a spear thrust had badly injured him. Katarina tended to his wounds and helps the TARDIS crew survive the events of the Troy siege. She joins Steven and the Doctor on their travels while Vicki decides to stay behind in Troy with the warrior Troilus. A sweet, simple young woman who cannot really cope with the concept that the universe has suddenly opened up to her, Katarina believes that she is dead, and that the Doctor is a god transporting her to the next life. She refers to the TARDIS the "temple" and also the "Place of Perfection", and literally worships the Doctor, referring to him as
