In the 'Emily Rose Story', Emily Rose is a girl who has to endure the horror of being possessed. She is the one that everyone in the story is either trying to help or figure out what's wrong with. Her experiences are what drive the whole story forward.
Miss Emily Grierson herself can be seen as a symbol of the dying Old South. Her decaying mansion represents the decay of the old social order. The rose in the title can be a symbol of love or pity for her. She was once a lady of high standing but as time passed, she was left behind, just like the Old South was being replaced by the new era. And her actions, which seem so out of place in the new society, are like the last gasps of the old traditions.

Some of the DCI Banks novels include 'Aftermath', 'Cold is the Grave', etc. These novels are known for their engaging crime and mystery plots. The main character, DCI Banks, is a complex and interesting detective.
