I don't believe Darlie killed her children, premeditated or otherwise. If one looks into the people who worked in her home, it may/or not, depending on our own mindset, be enlightening. I think there was someone so jealous of her and her lifestyle that they destroyed her children and tried to destroy Darlie. That would explain a great many of the "clues" we have seen in this case.
IMO there was someone who hated/was so jealous of Darlie that they killed those boys and tried to kill Darlie.
Until you understand how horrible it was for some of the European people during/after WWII, you might not understand where I'm coming from. But, I was a child who grew up with these people who came to the US after the war and it wasn't always pretty. Hell, in the sixties a neighbor of mine told me how her European relatives were jealous of her. I don't believe many of you understand the feelings that went on during that time period and how they affected people's minds.
