Read this passage from "The Tell-Tale Heart":
I thought the heart must burst. And now a new anxiety
seized me - the sound would be heard by a neighbour!
The old man's hour had come! With a loud yell, I threw
open the lantern and leaped into the room. He shrieked
once - once only. In an instant I dragged him to the floor,
and pulled the heavy bed over him. I then smiled gaily, to
find the deed so far done. But, for many minutes, the heart
beat on with a muffled sound. This, however, did not vex
me; it would not be heard through the wall. At length it
ceased. The old man was dead.
