Neighbours

The couple next door argued a lot.
Actually to call it arguing was unfair. She yelled at him a lot, but he never gave anything back.
"Why are you doing that?" she would shout at him while he was in the garden.
"You never do anything," she would yell as he fixed his car.
"You're lazy," she would scream as he took the dog out.
When she was struck and killed by a large branch which fell from the oak tree in the back garden, nobody believed it was an accident.
After the police quizzed him for days he returned home. Music was played in the house for the first time.
