10 More Times The Movie Killer Was Hiding In Plain Sight

Now for a classic Agatha Christie tale, where spotting the killer is all part of the experience So, did you manage to keep up with Poirot?

When proto-Kardashian Linnet Ridgeway is murdered on her honeymoon in Egypt, the obvious suspect is jealous Jacqueline 'Jackie' De Bellefort, once engaged to Simon Doyle, Linnet's new squeeze. She is indeed behind the murder yet she has an airtight alibi: during a furious (and staged) row with Simon aboard the ship, Jackie pretends to shoot him in the leg. She's taken to her cabin and knocked out with a shot of morphine, so who shot Linnet?

Accomplice Simon recovers the discarded pistol, races to Linnet's cabin and sprays her brains over the pillow. He returns to the lounge, shoots himself for real this time and throws the gun overboard.

The perfect crime? Almost.

Poirot knows the depth of Jackie's obsession because she straight out tells him at the start of the film: "One must follow one's star, wherever it leads... even to hell itself." That's enough to arouse the detective's suspicious mind, but do you still need more pointers?

The next fatal giveaway comes when Angela Lansbury is shot right between the eyes, now witness to a desperate cover up attempt from Jackie. How did Poirot guess this one? Because Jackie can't stop running her mouth - "My father taught me to be a crack shot," she brags to the Belgium OCD genius super-snoop. You should've kept your mouth shut Jackie
