Factual error: When Marlene goes to the greenhouse and is killed by the falling glass, this would never have happened. It is a federal law that all greenhouses, skylights, and entry-ways are to be made of safety glass. The glass would have to have been made of either a Tempered glass, which breaks in a thousand pieces, like a car window, or Laminated glass, which cracks but does not fall apart, like a car windshield. Neither one of these glasses would have killed her. Surely, law abiding citizens like Clare and her Husband would have followed the zoning laws that came along with building their greenhouse.
