Robin Miller travels to San Francisco following the apparently accidental death of her former lover Mary Oswell. When Robin learns that Mary died from anaphylactic shock she is positive it was no accident. Mary was working on a secret article on her lawyer; an article that could help earn Mary a promotion and help her boss right out of a job. Robin also learns that since their separation Mary was not wasting time pining away but involved with someone that no one knew about. As Robin gets closer to learning the truth she gets distracted by the possibility of a new romance until her own life is at risk.
