Hercule Poirot is at an exclusive Adriatic island resort for a holiday. But evil is aboard at his luxury hotel as the scene is being set for murder most foul amongst the distinguished clientele from the cream of Hollywood, Broadway and the British aristocracy. There are nine suspects in all - everyone has a motive and each has a cast iron alibi. Even the Belgian supersleuth is not above suspicion as he sifts through the puzzling clues in Agatha Christies's most elegant whodunit.
