In "The Interlopers" by Saki, the shift in point of view is significant in creating surprise. The author begins with an omniscient perspective, providing the background of the longstanding feud between Ulrich and Georg, which sets the stage for the conflict. However, as the narrative progresses, the focus shifts to Ulrich's point of view, limiting the reader's insight into Georg’s actions and motivations.
This creates a sense of uncertainty and builds tension, as the reader is left to piece together Georg's character and choices based on Ulrich’s limited perception of him. The final twist of the story, where the two men come to a moment of potential reconciliation only to be interrupted by an unexpected turn of events, is made all the more surprising because the reader has been drawn into Ulrich's perspective, unaware of how the situation might unfold from a broader view.
In sum, the point of view shift enhances the element of surprise by allowing readers to experience the emotions and thoughts of Ulrich, while simultaneously leaving them in the dark about Georg’s actions until the climax of the story.
