Synopsis As the wife of an eminent archaeologist, Agatha Christie took part in several expeditions to the Middle East. Drawing upon this experience and exhaustive research, she wrote this ingenious serial killer mystery set in ancient Egypt 4000 years ago. Seeking peace after her husbands death, the Ka-priests daughter Renisenb returns to her father's house on the banks of the Nile. But beneath the calm surface of his prosperous household lurk greed, lust and hate. When the grisly death of the beautiful and venomous concubine Nofret is dismissed as fate, Renisenb becomes increasingly convinced that the source of evil lurks within-and watches as the family's passions explode in murder! Though unlike any of her other novels, it still ends with a climax which few will anticipate.
