Open Window is a short story written by Saki, a pen name for British writer Hector Hugh Munro. The story follows a man named Framton Nuttel who visits a new town and is introduced to a woman named Mrs. Sappleton. Mrs. Sappleton tells Framton about her husband and her two brothers who went hunting three years ago and never returned. She believes they will come back through the open window, which she always keeps open for them.
As the story unfolds, Framton sees three figures approaching the house through the open window and becomes terrified. He flees the house, convinced that he has seen ghosts. Mrs. Sappleton's niece explains that the figures were actually hunters returning from their expedition.
The story is a clever and humorous tale that plays with the theme of mistaken identity and the power of suggestion. Saki's witty writing style and unexpected twist at the end make "Open Window" a memorable and entertaining read.
