She presents a program called Jemima Shore Investigates which looks into social issues & public scandals. Jemima is having an affair with a married politician, Tom Amyas, who's also very involved in social issues. At a loose end one night as she waits for Tom, Jemima sees a story in the newspaper about a nun found dead in an isolated tower. Jemima is taken back to her schooldays as she attended the convent school where the nun died. Blessed Eleanor's convent had been founded by a royal patroness, the Blessed Eleanor, who founded the Order of the Tower of Ivory & built a tower as a private retreat in the grounds. It was in this same tower that the nun, Sister Miriam, was found dead. It seems that she had accidentally locked herself in to the tower & starved to death. Jemima not only knew the convent but the nun. Sister Miriam had been Rosabelle Powerstock, a schoolfriend of Jemima's.
