The father is making sure his 3rd and final wish was granted. His wish was to put Herbert back in his grave. They put his coffin in the shed.
Once he entered the shed he went to the coffin. When he checked inside the coffin Herbert wasn't there. He was right behind him!
When he turned around and saw dead Herbert he ran. What he didn't know is he dropped the monkey's paw. When Dead Herbert was chasing him he saw the paw and grabbed it!
While dead Herbert picked up the paw he was still running. Herbert ran after him once he got the paw. He reached the house and closed the door.
After he locked the door dead Herbert was mad. Hr forgot he had the monkey's paw! He wished that his father was put into his coffin dead
Dead Herbert's wish came true, but it didn't end well for him either. When Herbert went to check the grave he was stabbed by his mother! She knew what dead Herbert did and had to kill him. So, she did just that and took the Monkey's Paw into a safe place. THE END!!
