The murder of Linnet Doyle occurs much earlier than in the classic story. With the entire ship trapped on the Nile, Poirot must navigate a web of three killers — each hiding a different truth. Y/n becomes both his greatest ally and most dangerous distraction. The third woman begins to fall for him, complicating the case. And Poirot, for the first time, feels something he cannot neatly arrange into order.
