Mystery Writer and Actress Carol Higgins Clark Passes Away at 66.

Carol Higgins Clark, a best-selling suspense novelist and daughter of Mary Higgins Clark, died at the age of 66 due to appendix cancer. She wrote more than a dozen novels on her own and collaborated with her mother on several Christmas-themed books. Her debut novel, "Decked," introduced Regan Reilly, a private investigator who would anchor almost all of her books. Carol's books were known for their humor, in contrast to her mother's psychological suspense. She also had a modest career as an actress, appearing in movies based on her mother's books.
