One summer weekend in 1949 â but not our 1949 â the well-connected "Farthing set", a group of upper-crust English families, enjoy a country retreat. Lucy is a minor daughter in one of those families; her parents were both leading figures in the group that overthrew Churchill and negotiated peace with Herr Hitler eight years before. Despite her parents' evident disapproval, Lucy is married â happily â to a London Jew. It was therefore quite a surprise to Lucy when she and her husband David found themselves invited to the retreat. It's even more startling when, on the retreat's first night, a major politician of the Farthing set is found gruesomely murdered, with abundant signs that the killing was ritualistic. It quickly becomes clear to Lucy that she and David were brought to the retreat in order to pin the murder on him. Major political machinations are at stake, including an initiative in Parliament, supported by the Farthing set, to limit the right to vote to university graduates. But whoever's behind the murder, and the frame-up, didn't reckon on the principal investigator from Scotland Yard being a man with very private reasons for sympathizing with outcastsâ¦ and looking beyond the obvious.
