I can’t remember the title or the author, but I believe it was published in the 90’s (possibly early 2000’s)
It was about a woman whose parents turned over their mail order catalogue clothing compan to her. It is set in “modern” England. The main character has a sister, I believe the sister’s name was Connie? She and her husband own a store where they sell art, textiles etc., from their trips overseas.
The main character also has a brother and sister in law (Judith?) who are both upset that their parents gave the younger sister (main character) control over the family business.
If anyone knows this, I would be grateful if you could post in the thread.
