Poirot: Appointment with Death Airs Sunday, July 25th on PBS

Tomorrow, Sunday July 25th, the third and final installment of this summer's Agatha Christie's Poirot Series X airs on PBS Masterpiece Mystery! Check your local listings for times.

Titled "Appointment with Death", archaeologist Lord Greville Boynton (brilliantly played by Tim Curry), accompanied by his universally despised wealthy second wife Lady Boynton, is in zealous pursuit of a major artifact in Syria. A curious array of onlookers has also gathered in the unforgiving desert heat — among them the tormented Boynton children, a psychiatrist, a nun, a travel writer and a cerebral but not exactly rugged Belgian detective, Hercule Poirot. When most of the camp returns from an expedition, they find Lady Boynton has been stabbed to death. How can Poirot make sense of a murder when most of the suspects weren't even present at the time of death? Poirot's investigation exposes red herrings, broken personalities and a tragic back story buried deep. Will Poirot give up in frustration or will the voices of his little grey cells sing out and solve the case?

David Suchet stars as Hercule Poirot in this adaptation of the novel by Agatha Christie, originally published in 1938.
