Shou Yuing

Shou Yuing was a young woman living in Carbury, in rural England. Along with archaeologist Peter Warmsly, she seems to have been a regular at a hotel run by Pat and Elizabeth Rowlinson. It was there that she met the Doctor and Ace while they were investigating an interdimensional distress call that they had traced to Carbury. Shou got on with Ace immediately; the young women shared an interest in explosives.

Shou owned a car, which was commandeered by Brigadier Lethbridge-Stewart when he needed to find the Doctor.
