Crooked House (2017)

A private investigator is asked by a former lover to investigate her grandfather's murder.  The family is rich beyond belief and all reside in the (admittedly very large) family home. Almost everyone has a motive since the old guy was a sadistic control-freak.

No one in the family is particularly sympathetic, which made the twists and turns enjoyable -- rather like in "Ten Little Indians." I'm not a huge Agatha Christie fan, but I was satisfied.
