who's the murderer on the orient express movie
Murder on the Orient Express Poirot proposes two possible solutions: either that a stranger boarded the train and murdered Cassetti, or that every one of the passengers, who had a connection to the Armstrongs, had all conspired to kill Cassetti together. The ostensible Mrs. Hubbard, in fact Daisy Armstrong's grandmother, the famous actress Linda Arden, confesses the truth of the second solution, yet M. Bouc and Dr. Constantine choose to present the first of the two to the Yugoslav police.
Return to Sender (Dexter) While eating breakfast at Rita's house, Dexter is called to a crime scene, only to discover that it is the same salvage yard where he committed a double murder the previous night. He finds Valerie Castillo's (Valerie Dillman) body lying in the Airstream trailer where he killed her and her husband Jorge (José Zúñiga), despite having thrown the corpses into the ocean. He deduces that the "Ice Truck Killer"—a serial killer with whom Dexter has a personal connection—dived underwater to retrieve the woman's body and plant it in the trailer. In the yard, LaGuerta, Sgt. James Doakes (Erik King) and Dexter's sister Debra (Jennifer Carpenter) discover a young Cuban boy, Oscar (Cesar Flores), hiding in the trunk of a car who claims to have seen somebody take Valerie into the trailer. He begins to fear discovery, and experiences his first nightmare: Debra is a serial killer with an identical modus operandi to Dexter. As the investigation proceeds, he attempts to shoot down each of his colleagues' leads on the case. When Debra asks him to read through her report on the killer, profiling a man sharing many of Dexter's characteristics, he second-guesses her theory and she is hurt. Worried about coming under suspicion, he throws all of his knives overboard from his boat, but while looking at the blood drops from his victims, he notices that Valerie's slide has a happy face etched into the blood. He realizes that this is a hint from the Ice Truck Killer, and plants Jorge's fingerprints and a dry drop of Valerie's blood onto a knife, which he hides in a car at the salvage yard. He convinces Doakes to organize another search of the yard, where an officer (Denver Dowridge) finds the knife. After successfully framing Jorge for Valerie's murder, Dexter discovers that Oscar's description of the man who "saved" him from Valerie is in fact Jesus Christ.
