Anne Perry and the Murder of the Century by Peter Graham
In 1954, teenagers Juliet Hulme--better known as bestselling mystery writer Anne Perry--and Pauline Parker went for a walk in a New Zealand park with Pauline's mother, Honora. Half an hour later, the girls returned alone, claiming there had been an accident. When Honora was found in a pool of blood with a brick close at hand, the girls were quickly arrested, later confessing to the killing. Their motive? A plan to escape to the United States to become writers, and Honora's determination to keep them apart.
