Caitlin Wallace
From Tardis Wiki, the free Doctor Who reference
Caitlin Wallace was a journalist. Going by the pseudonym Caitlin Jones to hide the fact she was the daughter of Dr Christopher Wallace, she visited the Cadogan tunnels with Matthew and Kevin. There, she encountered the Fifth Doctor and Tegan Jovanka. She explored the tunnels so that she could find the truth of her father's disappearance. (AUDIO: Rat Trap)
