Catherine Spencer went to a Catholic school. She worked as a High School English teacher. She married and had four children and five dogs.
When the menopause approached, Catherine began to write. She published her first novel in 1986. With friend and fellow writer Judith Bowen, she is a co-sponsor of the biennial Singletree Workshop, a weekend retreat for romance writers.
Now, Spencer lives with her husband in White Rock, in south of Vancouver, British Columbia. Their four children are adults, and they have five grandchildren.
