I love Agatha Christie's Poirot the mystery drama, do you?
Don't know about her , Agatha Christie's Poirot
It is a mystery drama adapted from a novel by Christie with such an interesting twist!
I see is it supposed to be a twist of fate?
Actually in each episode Poirot played both the detective in charge of the investigation and the protagonist (usually the murderer)  
It must be an interesting movie that ,who is the actor and the villain?
David Suchet was the actor who played the eponymous detective! The show ran for many episodes too, it was very  popular!
I love detective movie ,any other movie that's similar to the one in question?
