Le Mystère de la chambre 011

During some months it was common belief that roon 011 of some hospital was cursed and was evil. People died in there. Every friday morning, the nurses entered in this room of the intensive care unit only to find another dead patient. Of course they had been subjects to life-saving surgery and risky treatments but their life wasn't at stake anymore... Or was it?
The patients in room 011 kept dying, weekly, always on fridays.
