Any main channel, Netflix or Prime please?
I'm thinking of the sort of thing that is usually 3 to 4 parts and shown over consecutive nights.Channel 5 do a lot of these things - usually set in super smart houses the character couldn't afford. Sometimes they are longer but normally less than 5 episodes
i've seen lots but am sure there must be ones I haven't seen.
Stuff like these (which I have seen as samples):
Finding Alice (ITV husband falls down bannisterless stairs of dream home he designed) https://www.imdb.com/title/tt11127412/
The Catch (Ch 5) (seemingly perfect new bf of daughter freaks out her fisherman father) https://www.imdb.com/title/tt11127412/
The Woman in the House Across the Street from the Girl in the Window (Netflix) woman believes she sees murder in house opposite, parody thriller https://www.imdb.com/title/tt13315324/
The Stranger (Netflix, Harlan Coben) https://en.wikipedia.org/wiki/The_Stranger_(British_TV_series)
