Last Bus to Woodstock
Colin Dexter
 Two young women are waiting for a bus to Woodstock, and they decide to hitch a lift. Later that night, one of them, Sylvia Kaye, is found murdered and apparently sexually assaulted in the car park of the Black Prince pub in Woodstock. Suspicion falls on various characters. The body is reported found by John Sanders, a young man who, it later transpires, is addicted to pornography and sometimes paid Sylvia for sex. He admits to waiting for her on the night of her murder but found her dead. It turns out he interfered with the body but did not murder her. Inspector Morse discovers the lift was offered in a red car and guesses various bits of information about the owner. His discoveries lead him to calculate the chances of finding a red car in North Oxford which meets all the criteria. There is only one, and it belongs to Bernard Crowther, a don at the university who lives on Southdown Road. Crowther admits that, although married, he is having an affair with another woman. He admits giving a lift to two women and dropping them in Woodstock while on the way to meet his mistress. Crowther's wife kills herself, mistakenly thinking that her husband is the murderer; Crowther himself dies shortly afterwards from a heart attack, thinking that she is the killer. In the end it turns out it was neither of them but rather the other girl at the bus stop, Sue Widdowson, who was Crowther’s mistress. Crowther had dropped her off and had sex with Sylvia. Widdowson became insanely jealous, crept up behind Sylvia in the car, and hit her on the back of the head with a tyre lever lying in the lot. A further complication involves Jennifer Coleby who worked with Sylvia in an insurance office. Jennifer is having an affair with her boss, Palmer, and shares a flat with Sue Widdowson. Crowther types coded messages to a girlfriend who proves to be Widdowson. He leaves the messages with Coleby at her work, and she delivers them to Widdowson. The police are sent on a merry dance chasing them.
