A Judgement in Stone - 1977

Eunice Parchman becomes a housekeeper in the Cloverdale family. When she teams up with an ex-prostitute, things start to get really strange -- and dangerous for the members of the family.. Four members of the Coverdale family died in the space of 15 minutes on St Valentine's Day. Eunice Parchman, the housekeeper, shot them down on that Sunday evening while they were watching opera on television, and was arrested two weeks later. But the tragedy neither began nor ended there.
