Based on the classic Agatha Christie mystery, Agatha Christie’s Murder Is Easy tells the story of Luke Fitzwilliam who finds himself on the trail of a serial killer after meeting Miss Pinkerton on a train to London. She tells him about a series of suspicious deaths that have taken place in her village. When she later turns up dead herself – while on the way to visit Scotland Yard – Fitzwilliam realizes he needs to find the killer before yet more bodies start piling up. The two-part series features Penelope Wilton (Downton Abbey), Morfydd Clark (Lord of the Rings, Saint Maud), and Douglas Henshall (Shetland).
