Davies was a client of the theatrical agent, Ann Callender, and also worked as a secretary for Callender whenever she was short of work. Callender was the wife of TV producer David Croft, the director, co-writer and producer of "Dad's Army". Croft said that Davies "hastened to suggest herself for the part. After all, being in the office where the script first saw the light of day, she knew the requirements well." Davies went to see Croft in order to read for the part. Croft recalled that "She seemed to be just the right age and type to play the role."
