Sandra Pierce
Sandra "Sandy" Pierce was the wife of Tommy Pierce, who had to keep his career at Torchwood One a secret from her and led her to believe that he was merely a bus mechanic. She enjoyed reading.
Eventually, Tommy decided to tell her the truth, but she did not believe him. He brought home a device that allowed the user to absorb the contents of a book instantly. Sandra enjoyed it and accepted his life at Torchwood, with Tommy believing that she was secretly happy not to be married to a bus mechanic. However, Tommy later returned home and found that she had been retconned by Torchwood.
Sandra could tell that her husband was lying to her. Tommy suffered from alcoholism as a result of the burden of keeping secrets from her. The two drifted apart, and she left him. (AUDIO: Retirement Plan)
