This is the first book in the Inspector Morse series, published in 1975.  Beautiful Sylvia Kaye and another young woman had been seen hitching a ride not long before Sylvia's bludgeoned body is found outside a pub in Woodstock, near Oxford. Morse is sure the other hitchhiker can tell him much of what he needs to know. But his confidence is shaken by the cool inscrutability of the girl he's certain was Sylvia's companion on that ill-fated September evening. Shrewd as Morse is, he's also distracted by the complex scenarios that the murder set in motion among Sylvia's girlfriends and their Oxford playmates. To grasp the painful truth, and act upon it, requires from Morse the last atom of his professional discipline. 

On a quiet August morning, Judge Deborah Knott's father Kezzie makes a shocking discovery on a remote corner of his farm: the body of a man bludgeoned to death. Investigating this crime, Deborah's husband, Sheriff's Deputy Dwight Bryant, soon uncovers a long-simmering hostility between Kezzie and the slain man over a land dispute. The local newspaper implies that Deborah's family may have had something to do with the murder-and that Dwight is dragging his feet on the case. Meanwhile, Deborah is given a cigarette lighter that once belonged to her mother. The cryptic inscription inside rekindles Deborah's curiosity about her parents' past, and how they met. For years she has wondered how the daughter of a wealthy attorney could have married a widowed, semi-illiterate bootlegger, and this time she's determined to find the answer. But why are Deborah's brothers so reluctant to talk about the dead man? Is the murder linked to Kezzie's illegal whiskey business? And could his courtship of Deborah's mother have something to do with the bad blood between the two families? Despite Deborah's promise not to interfere in Dwight's work, she cannot stop herself from doing everything she can to help clear her brothers and her father from suspicion.
