Among the towering red cliffs of Petra, like some monstrous swollen Buddha, sat the corpse of Mrs. Boynton. A tiny puncture mark on her wrist was the only sign of the fatal injection that had killed her. With only 24 hours available to solve the mystery, Hercule Poirot recalled a chance remark he had overheard back in Jerusalem: "You see, don't you, that she's got to be killed?" Mrs. Boynton was, indeed, the most detestable woman he'd ever met. This classic Christie radio drama stars John Moffatt as Hercule Poirot.
