The word ‘shadow’ is talk about three times in Faulkner’s story, A Rose for Emily. It was stated before the murder of Homer, just after the murder, and when Emily died.
The shadow of Emily is her memories, her father’s death, her past, Homer’s death, the deterioration of the South, the undisclosed of Emily’s upstairs bedroom where she committed necrophilia and homicide. It is type of gothic imagery.
