From the Publisher:
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.
