No idea how I got sucked into this show as it’s incredibly slow and seems to mainly involve Nicole Kidman walking around before something happens in the final 2 minutes.
Also, I’m really lousy at whodunnits.
But anyway...
I think that Donald Sutherland’s character is the murderer.
I think it was because Elena was blackmailing him for some reason. Was there ever an explanation for how she and her husband were well off enough to afford a very expensive private school for their son? I don’t think we heard about their jobs (I know she was a sculptor but was that her actual job, and was she earning well?), and their apartment seems modest.
If I was to really eek it out, I’d guess that old Donny was either Elena’s father, or fathered her son, and was a source of income for her. Wasn’t there some conversation at the start between Elena and Grace about the two boys looking a bit similar? I thought this was to line up the Elena/Jonathan affair, but now I’m thinking the resemblance may be down to Donald.
Anyway, here’s my big theory.
The opening credits give it away.
It shows a happy little girl with red curly hair (so Nicole’s character as a child) playing. And then the bubble she’s playing with bursts.
Little girl. Bubble bursting. Kind of feels like something to do with a parent.
So pfiffle my mad theory, and add your own.
