The Daughters Of Cain by Colin Dexter

After an Oxford don is found stabbed in his flat, a seasoned detective and his steadfast sergeant follow a trail through cloistered college politics, petty theft, and a second violent death, with a missing knife and a vulnerable young sex worker at the investigation’s center. As they uncover threads of drug dealing, blackmail, and past grievances, the case exposes the quiet tragedies of several women tied to the victim, testing the detective’s judgment and resolve and culminating in a bleak revelation that offers truth but little solace.
