The first of a new-look series of Hercule Poirot books for the 21st century From seat No.9, Hercule Poirot was ideally placed to observe his fellow air passengers. Over to his right sat a pretty young woman, clearly infatuated with the man opposite; ahead, in seat No.13, sat a Countess with a poorly-concealed cocaine habit; across the gangway in seat No.8, a detective writer was being troubled by an aggressive wasp. What Poirot did not yet realize was that behind him, in seat No.2, sat the slumped, lifeless body of a woman.
