Elsbeth extends another invitation to Oliver, drawing him back to Saltburn, where their connection deepens, and he assumes the role of caretaker and companion during Elsbeth’s final days. Predictably, Elsbeth passes away in her hospital bed. However, as the dust settles, Oliver’s grand scheme is unveiled. It becomes evident that he had meticulously orchestrated the entire sequence of events since his initial encounter with Felix, strategically gaining sympathy and access to the inner circle. The culmination of Oliver’s Machiavellian plot is the successful theft of the Catton family’s vast fortune. To achieve this, he poisons Felix through a manipulated confrontation in the maze, leaving him helpless. Oliver also manipulates Venetia’s vulnerable state, providing her with a razor, knowing she might succumb to self-harm in her grief-stricken moment. Claiming responsibility for breaking her, he orchestrates Elsbeth’s demise, whether through a slow poisoning or suffocation with a pillow, maintaining a calculated ambiguity. With his inheritance secured, Oliver jubilantly embraces his newfound wealth and status as the owner of Saltburn, celebrating with a sinister dance to the beat of ‘Murder on the Dancefloor.’ His flawless execution of the plan propels him to the pinnacle of the social hierarchy, reveling in the success of his devious machinations.
