Vestal Smith
From Tardis Wiki, the free Doctor Who reference
Vestal Smith was a 24th century computer programmer. She was married to Reginald Smith but often met with Archie Sylvest when his wife, Nimo, was away. Archie considered her to be a warm and understanding person.
In 2310, Vestal invited Archie to her house at 25 Lydall Street for dinner and Voxnic, but Archie instead encountered her husband there. He attempted to convince Reginald that the relationship was entirely platonic and went to a Voxnic bar with him to do so. (PROSE: The Twin Dilemma)
