A Judgement in Stone - Ruth Rendell

Four members of the Coverdale family – George, Jacqueline, Melinda and Giles – died in the space of fifteen minutes on the 14th of February, ‘St. Valentine’s Day. Eunice Parchman, the housekeeper, and the prosaically named Joan Smith shot them down on a Sunday evening while they were watching opera on television. Two weeks later Eunice was arrested for the crime.

But the tragedy neither began nor ended there.
