Death Is Now My Neighbour by Colin Dexter

A young woman is shot through her kitchen window in North Oxford, drawing a detective duo into a case that leads from a quiet suburban street to the cutthroat contest for the mastership of an Oxford college. As they uncover blackmail, adultery, and long-buried secrets among academics and their spouses, a second killing exposes the link between the crimes. Ambition and hypocrisy converge inside the ivory tower, culminating in a coolly reasoned reveal of the murderer.
