Hercule Poirot's vacation in the Holy Land is interrupted by death in Petra, where the lifeless body of Mrs. Boynton, a detestable English woman who cowed her family and strangers alike, is found atop the rose red cliffs. Though her family claims her heart failure was a natural event, the tiny puncture mark on her wrist is a clear sign of the fatal injection that really killed her.
