Appointment with Death

When a former prison wardress who dominates the lives of her three adult stepchildren and her daughter is found dead at an archaeological dig near the Dead Sea, there are a great many suspects.
Emily Boynton, the stepmother to three children, blackmails the family lawyer into destroying a second will of her late husband that would have freed the children from her dominating influence. She takes herself, the children, and her daughter-in-law on holiday to Europe and the Holy Land. At a dig, Emily is found dead and Hercule Poirot investigates.
