The events of "Storm Front" and "Fool Moon" cause Murphy to distrust Harry, and she reacts in a hostile and violent manner when she suspects he had a hand in the victims' deaths. She also takes action against Harry when she thinks he is keeping information from her because of his other commitments, such as to the White Council. In both books she physically assaults him and attempts to arrest him. However, the events of "Grave Peril" and "Summer Knight" lead her to put more trust in him, and she becomes one of his closest friends once he takes the plunge and 'clues her in' to the true reality and nature of things.
