Book excerpt: A young girl is murdered in a cemetery. And Wexford's doctor has prescribed no alcohol, no rich food and, above all, no police work. When a young girl's body is found in a London cemetery and the local police, under the command of Wexford's nephew, are baffled, Wexford decides to brave his doctor's wrath and the condescension of the London police by doing a little investigating of his own. A compelling story of mysterious identity and untimely death, Murder Being Once Done is Rendell at her most sublime. With her Inspector Wexford novels, Ruth Rendell, winner of the Mystery Writers of America Grand Master Award, has added layers of depth, realism and unease to the classic English mystery. For the canny, tireless, and unflappable policeman is an unblinking observer of human nature, whose study has taught him that under certain circumstances the most unlikely people are capable of the most appalling crimes.
