A ghost story from Colombo General Hospital

This case happened at Colombo General  Hospital's Intensive Care Unit where patients always died in the same bed and on all Sunday mornings at 11 a. m, regardless of their medical condition. This puzzled the doctors and some even thought that it had something to do with the supernatural. No one could solve the mystery as to why the deaths took place at 11 AM.   So a hospital-wide expert team was constituted and they decided to go down to the ward to investigate the cause of the incidents. So on the next Sunday morning, a few minutes before 11 a.m., all doctors and nurses nervously waited outside the ward to see for themselves what the terrible phenomenon was all about. Some were holding wooden crosses, prayer books and other holy objects to ward off evil. The clock struck 11...    And then......
