When a murder occurs in beautiful Hawaii, the suspects are two young mainlanders on their honeymoon. Mayann Acker is eighteen-years-old. Her husband, William, is twenty-eight and just out of prison.

Linda Spalding is chosen as a juror for Maryann's trail. Surprisingly, the chief witness against her is William. Spalding has her doubts, but on the last day of the trial she is abruptly dismissed from the jury. Maryann is found guilty. Who Named the Knife is the story of how, eighteen years later, Spalding tracks down Maryann and uncovers much more than the answer to the question of her innocence. A complex journey into the twists of fate that spin two lives down different paths, Who Named the Knife offers profound insight into the human heart.
