Aboard a plane, a woman dies in her seat, apparently the victim of a wasp sting. Then, a venom-tipped dart from a South American blowgun is found in the aisle. Everyone is suspect, including Hercule Poirot, who was sitting a mere fifteen feet from the victim. Poirot finds closer ties between some of the passengers on the plane than they would admit, but who could have wanted the woman dead? He must find the real murderer and the truth of the case, if only to clear his own name. Read by Hugh Fraser.
