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.
