Question - the mother's involvement
I watched the movie (online, free as part of my subscription from my Rental site), but a few things I didn't catch (too much noise going on in the street outside and if I "rewind" the movie with the set up on the site, it starts the movie from the beginning so I missed some stuff).
Anyway, it was the part where the mother is responsible for putting the architect in this pit. Was this revenge for him murdering her husband or was she involved with the architect and put him down there to "keep" him?
Alot of things were confusing for me, but it was a not bad movie all the same (for free anyway).
