Gaudy Night
Dorothy L. Sayers
 Harriet Vane returns reluctantly to Oxford to attend the Gaudy dinner. Expecting hostility because of her notoriety, she is surprised to be welcomed warmly by the dons, and rediscovers her old love of the academic life. Some time later the Warden of Shrewsbury writes to ask for help. There has been an outbreak of anonymous letters, vandalism and threats, apparently from someone within the college, and a scandal is feared. Harriet, herself a victim of poison-pen letters ever since her trial, reluctantly agrees to help, and spends much of the next few months resident at the college, ostensibly to do research on Sheridan Le Fanu and assist a don with her book. As she wrestles with the case, trying to narrow down the list of suspects and avert a major scandal, Harriet is forced to examine her ambivalent feelings about love and marriage, along with her attraction to academia as an intellectual (and emotional) refuge. Her personal dilemma becomes entangled with darkly hinted suspicions and prejudices raised by the crimes at the college, which appear to have been committed by a sexually frustrated female don. Harriet is forced to re-examine her relationship with Wimsey in the light of what she has discovered about herself. Wimsey eventually arrives in Oxford to help her, and she gains a new perspective on him from those who know him, including his nephew, a current undergraduate at the university. The attacks build to a crisis, and the college community of students, dons and servants is almost torn apart by suspicion and fear. There is an attempt to drive a vulnerable student to suicide, and a physical assault on Harriet that almost kills her. The perpetrator is finally unmasked by Wimsey as one of the college servants, revealed to be the widow of a disgraced academic at a northern university. Her husband's academic fraud had been exposed by one of his fellow dons there, destroying his career and driving him to suicide. The don has since moved to Shrewsbury College, and the campaign has been the widow's revenge against intellectual women who move outside their "proper" domestic sphere. At the end of the book, Harriet Vane finally accepts Wimsey's proposal of marriage. (Their marriage and honeymoon—interrupted by another murder mystery—are depicted in Busman's Honeymoon.)
