Women's Murder Club premiered on ABC on October 12, 2007. Based on James Patterson's bestselling novels, four working women in San Francisco - a detective, a district attorney, a medical examiner and a reporter - use their expertise and unique talents to solve murder cases. Each woman is successful in her own field, but because of their unique friendship, they realize that pooling their resources during investigations leads to undiscovered clues and answers in both work and their personal lives.
