Writing under the pseudonym Barbara Vine, Ruth Rendell departs from her famous detective team of Wexford and Burden to tell a gripping tale of family madness. Vera Hillyard is a domineering and possessive woman who strives for obsessive control over a malicious older son, a youngest son who is--or isn't--illegitimate, and a daughter who is a devoted sister to her younger brother. The daughter secretly seeks to escape Vera's grasp and instead provokes a murder. This winner of the 1986 Edgar Award for best mystery novel belongs to the genre of old murders reconsidered and the question of who did what to whom and why is teasingly left unresolved.
