Tracey and his son Peter were members of the Hecate Cult. They nearly sacrificed Brendan Richards on 21 December 1981 before being defeated by Sarah Jane Smith and K9. Tracey and the other cult members were arrested by the police and were charged with attempted murder eight days later. Pollock told Sarah Jane that Tracey usually visited his mother in Cirencester on Sundays. (TV: A Girl's Best Friend)
