This is a real must for any fans of mystery, Agatha Christie or simply just excellent television. It's a very dark tale of justice and overpowering love. It's all about the bringing about of justice for a dead innocent girl. Miss Marple is called in by a recently deceased Jason Rafiel (Caribbean Mystery) to explain why Verity Hunt was murdered, and bring her killer to justice. A dark cloud hangs over Jason's son Michael who was acquitted of Verity's murder, but remains the number one suspect. There are some truly wonderful performances in Nemesis, the three sisters especially, the bodyguards, but it's Joan that shines, she is truly so good in this, I think it's her finest performance in the role. A must mention too for Liz Fraser who plays the mother of another dead girl Nora Hunt, she is so good it's heartbreaking. Overall I'd consider this one of the best Agatha Christie adaptations of all time, the later version is shocking by comparison.
