Tell Tail Heart -alternative ending in the point of view

“officer there was a 911 call about some shrieking can you respond.”

“Yes operator I will bring back up just incase.”

The door opens the police officers are immediately greeted by a suspiciously hyper suspect. The police are given a tour around the house and they are lead into the owner of the houses room. They are sat down and left to chat. They don’t notice it but the man is sweating profusely, darting around very nervously, and mumbling almost silently. “They know they know they know.” He bursts out “I ADMIT THE DEAD!” He opens up the floor boards to reveal a dismembered corps.
