Explanation:
In "The Open Window" by Saki, the character who says these words is Mrs. Sappleton. While waiting for Mrs. Sappleton, Framton is told by Vera, her niece, that there has been a tragedy three years before and that Mrs. Sappleton's husband and two of her brothers went for hunting and never returned. When Mrs. Sappleton comes and explains that the window is open because she is waiting for her husband and her brothers, Framton begins to feel uneasy.
