Sarah Jane Smith (audio series)

Released between 2002 and 2006, Big Finish Productions' Sarah Jane Smith series of audio dramas explored the life of Sarah Jane Smith in the years after she was left on Earth by the Doctor. The series took place in the present day, and apparently after the events of TV: A Girl's Best Friend. K9 Mark III did not appear in these stories, as he had broken down and was in a box in Sarah Jane's attic; he was dismantled by Hilda Winters when she found the box.

The final episode of the series, Dreamland, was released only a few weeks before Sladen returned to Doctor Who as Sarah Jane in School Reunion. This return to Doctor Who led to the commissioning of a new TV spin-off series, The Sarah Jane Adventures, which in turn resulted in the Big Finish audio series terminating after nine stories.

The TV continuation does reference the events of the audios, i.e. School Reunion revealed that K9 had been non-functional for some time. There is also mention of Aunt Lavinia leaving Sarah the house. (TV: The Wedding of Sarah Jane Smith)
