The author of the black cat uses flaahback to tell the story. how soes this create suspense

In the black cat, the image of the hanged cat that is left on the burnt building and the markings that look like a noose on the new cat are repetitive images of death and the murderous deed that the narrator committed. Like the endless beating of the victim's heart in "Tell Tale Heart," the constant reminder of the death of the cat through the images of nooses and cats with one eye remind the narrator of his evil deed. The narrator blames the cat (in his mind melding together the two cats into one evil cat) "whose craft has seduced me into murder."

Hope This Helps!    Have A Nice Day!!
