Question: Was the doctor (the owner of the sailboat in the beginning) in on Laura's planned disappearance? Or was the bad weather just a coincidence and gave her the chance to escape? Just though it was weird because her husband commented that she only gets on a boat like once a year, so I don't know how she could have planned her escape so perfectly.
Question: I don't live in the US; is it normal for a gym to contact next of kin and offer condolences when someone is believed to have died? Or is it for plot convenience? Where I come from, any cancellations of memberships, etc, would all be done in writing.
Question: Why after receiving a phone call from Laura's friend at the YMCA does her husband go looking through all her stuff on the bed? Then he finds the ring in the toilet. It just makes no sense why he's tearing through her stuff.
Question: When she discovers the cans are all in order, why doesn't she run out the back door which is right there? Why does she run to the front door?
