The guy explains how people thinks he's mad but he really isn't. He also states how much he loves the old man but his eyes freak him out and he doesn't like them.
The guy goes into the old mans room and he watched sleep every night at midnight to see him without the eye because hes sleep and the eye is closed so he plans to only kill him while hes awake.
The guy is very upset because the eye of the old man is taunting him and he needs to get rid of him forever..so he decides to kill him.
The guy kills the old man by fliiping a bed overtop of him. Now the eye will be gone forever but now the old mans heartbeat is driving him crazy.

The guy finallu gives himself up under the pressure of the heartbeating and the police.
