A maid up ending of the Cask of Amontillado  (i got an A-)
There was none

At precisely 10:30 A.M. I got a call from a Mr. Machiano saying while
renovating a palazzo his men found the bones of a human.  When I got to
the scene one of his employees showed me to the bones.  The clothes were
still on the carcass.  I asked Mr. Machiano how the body was discovered,
"My men were knocking down the walls and one of them found a skeleton
with its clothes on, and that’s when I called you."  I asked whom he
bought the palace from.  "A man I would say in his early eighties, named
Montresor."  I then left to learn about this person..  I found out that
he is living with a cousin right near his old home.  I decided to stop
by and ask him a few questions hoping he will remember or know
something.  After about an hour of getting "I do not know. What are you
talking about? Please leave." I realized this was a waste of time and
decided to go.  
Later that night while eating dinner I decided the next morning I would
go back to the crime scene to check for clues.  The next morning I
called Mr. Machiano and asked him to meet me at the palazzo.  As I
approached the body I began to feel a little queasy from last night’s
dinner but luckily I brought some herbal tea to help soothe my stomach. 
Anyway, I began to search the ground around the body hoping to find some
clues.  I noticed a gold bracelet on the ground near the body, and  it
read Montrsor.  I decided to do a little more research on this man.  I
went to the station and asked the secretary to show me the file on any
person missing for more than 20 years.  The list only had about five
people on it with a brief description.  There was a man by the name of
Fortunato on it who has been missing for about 50 years.  He was last
seen wearing a motley.  I then put two and two together and after some
investigation, I found out that the carcass was indeed Fortunato.  Later
that afternoon I decided to visit Mrs. Fortunato.  She took the news
pretty well, but I guess she had a feeling he was dead  She said "The
last time I saw him was fifty years ago during carnival season."  
I went back to Montresor’s house and told him that "Next to Fortunato’s
body was a gold bracelet with your name on it."  He still claimed to
have nothing to do with the murder and had no idea how his bracelet got
near the body.  "It must have fallen off and sunk into the mortar." 
When I said that I could sense his nervousness.  I asked him if he was
okay, then I heard him mumble something.  I asked him to say that louder
I could not quite hear that.  He said "I killed him, and I do not even
regret it."  He kept the murder a secret all these years because he did
not want to go to jail.  "Now you are definitely going to jail."  I felt
kind of bad bringing an eighty year old person to jail, but I had no
choice.  
Epilogue
