David (Cat's Cradle: Warhead)
From Tardis Wiki, the free Doctor Who reference
Miss David was a female human who ran a carpet shop in Antalya, Turkey. She was an old friend of the Doctor, who had seen the dimensional strings created by the ancient Gallifreyans reflected in, among other places, the patterns of her carpet shop. (PROSE: Cat's Cradle: Time's Crucible)
In 2007 Miss David reluctantly assisted Ace in negotiations to hire a group of Kurdish mercenaries. The Seventh Doctor had one of her carpets at his house in Kent. (PROSE: Cat's Cradle: Warhead)
