On the short flight from Le Bourget to Croydon the woman in seat number two dies from a wasp sting. Hercule Poirot is not convinced that a wasp sting caused the death. With a large cast of characters to choose from in this `locked-room' mystery and working with Scotland Yard and the S�ret� he sets out to discover the truth in his very methodical way. Christie satirizes both her own and her husband's profession in this novel with the character Daniel Clancy, a detective story writer and a couple of French archaeologists.
