Murder in Venice, an explanation of the film’s ending by and with Kenneth Branagh

Let’s start with Rowena. In the final Murder in Venice, we discover that she is the culprit not only of her daughter’s murder, but also of a séance attended by Poirot, conducted by his friend Ariadne Oliver. The woman, who couldn’t live without Alicia, decided to control her by coming up with a plan to distance her from her boyfriend Maxim. To prevent the girl from meeting him again, Rowena began gradually, every day, to poison her with a certain hallucinogenic honey. A year after Alicia’s death, the woman arranges a seance with the medium Joyce Reynolds in an attempt to kill her and Leslie Ferrier, Alicia’s doctor, because she is convinced that both, knowing what happened, are blackmailing her for money. If his plan had succeeded, the two would have died under the pretext of revenge against the children, given that one was a doctor and the other a former military nurse. However, when Poirot arrives, not anticipating the detective’s presence, Rowena begins to poison him with tea in order to confuse him.
