 CONT: When George brings the girls back to the bedroom it is  daytime. The girls draw the sheer drapes, which still allow a  considerable amount of natural light in the room. He leaves the  room, and when he returns a few minutes later it is completely pitch  black. He soon discovers the body of one of the girls, mistaking her  blood, by its feel, as chocolate sauce. Later during the  investigation they show a flash back to only moments after George  discovers the body, and the room is once again filled with natural  light streaming through the sheer windowpanes.
