A Judgement in Stone by Ruth Rendell
On Valentine’s Day, four members of the Coverdale family–George, Jacqueline, Melinda and Giles–were murdered in the space of 15 minutes. Their housekeeper, Eunice Parchman, shot them, one by one, in the blue light of a televised performance of Don Giovanni. When Detective Chief Superintendent William Vetch arrests Miss Parchman two weeks later, he discovers a second tragedy: the key to the Valentine’s Day massacre hidden within a private humiliation Eunice Parchman has guarded all her life. A brilliant rendering of character, motive, and the heady discovery of truth, A Judgement in Stone is among Ruth Rendell’s finest psychological thrillers.
