During a flight from France to England, Madame Giselle, a French moneylender, is found dead aboard the plane. At first, her death is thought to be from natural causes—the result of a wasp sting—but it soon becomes clear that it was premeditated murder. Among the passengers on board is the famous detective Hercule Poirot, who takes part in the investigation. He uncovers a series of unexpected facts, makes several brilliant deductions, and ultimately exposes the culprit.
