"The Black Cat" & "Tall-tale Heart" by Edgar Allan Poe

"The Black Cat" and "Tall-tale Heart"  

Both stories resemble with each other. Both begin with the satement that the narrator is not mad; Both kill a woman (or an old man); conceal the corpus in a wall (or under the planks). The policemen come and investigate the room throughly and think that the narrator is not the criminal; but at the very last moment, the narrator reveals that he himself is the criminal by knocking the wall (or saying, "Tear up the planks!").  

Both stories develop well, increase tention skillfully driving the reader to turn the pages one after another till the end. They are both horrible, cruel, and full of suspense. The reader is instantaneously abosorbed in the story and cannot stop reading. 

They are self-destruction stories.
