"The Library Window" is Margaret Oliphant's subtle supernatural tale of a young woman spending a summer with her elderly aunt in the Scottish town of St. Rule's. She becomes fascinated by a mysterious window in the College Library opposite their home—one that the townspeople cannot agree even exists—and discovers she possesses an unusual ability to perceive what others cannot. As her perception of the window's interior deepens, she begins to see signs of a mysterious occupant, drawing her into an increasingly absorbing and inexplicable mystery.
