What is the theme in The Monkey's Raincoat by Robert Crais?

Women and innocence is the main theme of the book. In the novel, Elvis Cole is a protector of innocence and a defender of women and children. The more Elvis sees that Ellen is a victim who has become subservient, with low self-esteem, the more he wants to help her and transform her. Instead of Ellen getting power from within herself, she seems to be saved, like a damsel in distress, not just from kidnapping but from her own self-image. This tendency in Elvis goes beyond Ellen and her innocent son Perry.
