Peggy Garratt is shopping one day when she collides with the Doctor and Turlough. She spills her groceries, and the Doctor helps her pick them up. She heads home and finds that her husband, Stan, has come home early because the factory at which he works has shut down. Peggy finds a necklace in her groceries that must belong to the Doctor. She contemplates wearing it next week to a party. She and Stan are worried that someone will know they have it and try to steal it, so he takes it to hide it and then put a lost-and-found ad in the newspaper.
