Unlike Steed's other partners, we know few things about her. She enlisted at an early age in the Intelligence Service as a trainee, under the number 69. Her first contact with the bowler-hatted agent is described in the first episode of season 6: The Forget-me-Knot. This was a rather spectacular meeting: thinking Steed is the "enemy" of her training, she pounces on him before she realizes she has made a mistake. Shortly after, she makes Steed's acquaintance. During their talk, we learn John Steed is considered as an idol by all agents, Tara included. She then helps him to resolve the episode's investigation.
