I was so sure I was right that without touching the nail I pressed the button and tried to raise the window.

I moved the bed so that I could look closely. The nail there looked the same as the one I had just seen. “Then…the window could not have been the means of escape!” So, I returned the nail, pressed the button and again tried to raise the window. “Now I knew that the killer could close the window from outside and the window would lock itself. Indeed, I found a button which, when I pressed it, opened an inner lock. There had to be a hidden lock, I thought, inside the window. Second, if it was not the nails which were holding the windows closed, then something else was holding them closed, something hard to see, something hidden. Two things seemed clear: first, there had to be something wrong with the idea that the nails were holding the windows closed. “That’s the problem, Dupin! Perhaps - perhaps if you pulled out the nail…” How could the murderer put the nail back in its place?” This was the fact that stopped the police. Yet anyone could see the nails which held the windows tightly closed. After the murderer had left he could have closed the window from the outside but he could not have fastened the nail. The killer, and I believe there was just one, escaped through one of these windows. “I knew that what seemed impossible must be proved possible. My friend Dupin was now explaining to me what he had learned when we visited the scene of the crime. And yet, there was no one in the room when police arrived moments after the attack. One voice was speaking in French the other voice had not spoken even one word that anyone could understand. The door and windows to the house all firmly closed, locked on the inside. But the old woman’s body was outside, behind the house. The knife that had killed the old woman, almost separating head from body, was in the room. The damage to the daughter’s body suggested a killer of superhuman strength. Murder had come to the old house on the street called Rue Morgue! Murder had come and gone and left behind the dead bodies of an old woman and her daughter. The story was originally adapted and recorded by VOA Learning English. We present the fourth of five parts of the short story "The Murders in the Rue Morgue," by Edgar Allen Poe.
