Reason behind 3rd husband's death not discovered??!!??
As much as I like this film, I have to wonder why the death of Catherine's 3rd husband, the museum curator, was not realized to be a murder. He was a multi-millionaire in his 50's -- right there, there would have been at least one opinion in regard to an autopsy, which under the circumstances would DEFINITELY have been performed. He would not knowingly have taken Penicillin, so someone else must have given it to him. The spouse would be an immediate suspect, and would have at least been arrested, if not charged and tried -- gimme a break!
