An Invitation to Murder — A.G. Barnett

Actress, icon and darling of the nation, she was the queen of TV crime drama. Then she turned fifty. When replaced on the show by a younger woman, she thinks her days in the limelight are over when an invitation to a murder mystery party from an old friend throws her back into the public eye. This time as a murder suspect. After playing a detective for years, Mary must now become one as she tries to prove her innocent with the help of her puppy-like brother and her surprisingly useful friend and assistant, Dot.
