Old Flames (short story)

Summary
The TARDIS materializes near an 18th-century manor, where the Doctor nearly drowns in a frozen lake while following giant cat footprints. He is rescued by the kindly Rector Adams, and eventually recovers and decides to go back to the TARDIS - but on his way he and Sarah see a 20th-century double-decker bus trundling through the woods and decide to remain and investigate. Adams invites them to accompany him to Lady Huntingdon's ball, where the Doctor meets an old "friend" - Iris Wildthyme, fellow renegade Time Lady.

She's brought her human companion, a young man named Turner, to the ball in the hopes that he'll marry Lady Huntingdon's granddaughter Bella and Iris will inherit the estate. The ball ends badly when Adams' body is found outside, mauled by a giant animal. The Doctor attends a dinner with Lady Huntingdon, Iris, Bella and Turner, where it is revealed that Lady Huntingdon and her daughter are shape-shifting cat aliens and that Lady Huntingdon is fully aware of Iris' plans and intends to take Iris' TARDIS, the bus which the Doctor and Sarah spotted earlier.

Bella refuses to help her grandmother, claiming that Earth is the only home she knows now, and Lady Huntingdon transforms into the cat-shape in which she killed Adams and heads into the woods to find Iris' TARDIS. The Doctor beats her to it and uses a Time Lord dimensional message capsule to trap her in a pocket dimension. The Doctor and Sarah then leave, and Iris sets off as well, leaving Turner behind with Bella.
