I just finished this series, it's only 3 episodes. It's based on Agatha Christie's novel, I don't actually read novels but this series made me want to read the works of this great author. The story is excellent, you literally don't expect who the killer is, I had previously watched the series "The ABC murders" but to be honest it wasn't as good as this series which I liked a lot, each character has a story that happened to them that is shrouded in mystery, the soundtrack and acting are great. (9.5/10)
