In The Open Window, the rising action occurs as Frampton Nuttel arrives at the Sappleton home and is told the story by Vera, Mrs. Sappleton's niece. She explains to him in great detail that the window remains open as a memorial in waiting. Her aunt expects the return of her husband's hunting party which was lost in the marsh.
Vera is very convincing in her story, she has Mr. Nuttel scared to death and convinced that Mrs. Sappleton is insane.
The climax of the story is when Mrs. Sappleton announces that she sees her husband and brothers coming towards the house.
"Nuttel turns to Vera to extend his sympathy, but Vera is staring out through the open window with a look of horror in her eyes. Nuttel tums around to the window and sees Mrs. Sappleton's husband and brothers walking across the lawn, a spaniel following them, and hears a voice singing "Bertie, why do you bound?'' Nuttel grabs his hat and walking stick and flees from the house."
The resolution of the story occurs as Mrs. Sappleton, puzzled by Mr. Nuttel's hasty departure from her home, is told by Vera that he ran out of the house because of the dog that was approaching the house. You see, said Vera in the resolution, he told me he was terrified of dogs.
