SUMMARY: Linnet Doyle is young, beautiful, and rich. She's the girl who has everything—including the man her best friend loves. Linnet and her new husband take a cruise on the Nile, where they meet the brilliant detective Hercule Poirot. It should be an idyllic trip, yet Poirot has a vague, uneasy feeling that something is dangerously amiss...

SUMMARY: Among the towering red cliffs and the ancient ruins of Petra sits the corpse of Mrs. Boynton, the cruel and tyrannizing matriarch of the Boynton family. A tiny puncture mark on her wrist is the only sign of the fatal injection that killed her. With only twenty-four hours to solve the mystery, Hercule Poirot recalls a remark he overheard back in Jerusalem: "You do see, don't you, that she's got to be killed?" Mrs. Boynton was, indeed, the most detestable woman he had ever met.
