Plot question (major spoilers)
Okay, sometimes I miss obvious things in movies so feel free to call me an idiot for asking this. How did Mrs. Harrison die? Because she never took the poison, right? So was it just one big coincidence that she fell into a coma that evening?
And then why did Kay rip the one page out of the notebook? Was she trying to protect Ralph, or trying to frame him? The comment by the police inspector at the very end of the movie suggests she was trying to implicate Ralph by hiding the one page from the diary, but if that was really her intention then why wouldn't she burn it?
